Description

Docking connector assembly for electric vehicle charging device {DOCKING CONNECTOR ASSEMBLY FOR ELECTRIC VEHICLE CHARGING APPARATUS}

The present invention relates to a docking connector assembly including a structure for electrical connection between devices, and more specifically, to a docking connector assembly for an electric vehicle charging device to compensate for minute position errors between devices.

Electric vehicle (EV) is a future convergence technology that is receiving interest and investment from governments and companies around the world along with the global green growth policy. Accordingly, the automobile industry is rapidly changing the market demand axis from conventional oil-based vehicles to electric vehicles.

As the demand for electric vehicles increases, not only the technology for building infrastructure (charging devices, power supply networks, etc.) for smooth use of electric vehicles, but also recently methods and technologies for charging multiple electric vehicles have been developed.

Generally, in the case of a conventional electric vehicle charging system, an electric vehicle charger is provided in a part of a space where a vehicle can be parked, such as an underground parking lot, and a person who wants to charge the vehicle parks at a place where the electric vehicle charger is provided and charges the electric vehicle. It is operated in this form.

However, parking spaces where electric vehicle chargers can be installed are quite limited and the cost of building infrastructure to install electric vehicle chargers is quite large, so the demand for chargers is explosively increasing due to the increase in the number of electric vehicles. To solve these problems, demand for mobile charging devices has recently been increasing.

Meanwhile, a separate connector may be provided to couple the mobile charging device directly with the electric vehicle or to couple the mobile charging device with the stationary charging device. The connector can serve as an electrical/physical bridge that transfers power from the battery contained in the mobile charging device to the stationary charging device and the electric vehicle. However, not only is the size and weight of the mobile charging device quite large, but also the amount of power supplied per hour through the connector is quite large, so if the connector is not coupled properly, breakdowns and fires may occur. The connectors developed to date have had the problem of being difficult to commercialize due to the high incidence of mating defects when a slight positional error occurs between the mobile charging device and the electric vehicle/stationary charging device.

The present invention relates to a connector assembly developed to solve the above problems, and provides a connector assembly capable of electrical/physical coupling without problems even if some positional error occurs when docking the connector.

1 shows an exemplary diagram of a system schematically showing a docking connector assembly related to an embodiment of the present invention.

As shown in FIG. 1, the docking connector assembly 1000 of the present invention may include a first connector 100 and a second connector 200. According to the embodiment, the first connector 100 may be provided on a moving body, and the second connector 200 may be provided on a moving body or a fixed body. For example, the mobile object may be a charging cart 100a, and the fixed object may mean an electric vehicle or a separate charging device. The charging cart 100a may be provided with a first connector 100, and the electric vehicle may be provided with a second connector 200. The detailed description of the device provided with each of the above-described first and second connectors is merely an example, and the present invention is not limited thereto.

According to one embodiment of the present invention, the charging cart 100a may include a charging module for charging an electric vehicle. According to an embodiment, an electric vehicle may mean a vehicle that moves by generating driving force through a battery engine. An electric vehicle may refer to a vehicle that can be driven without an internal combustion engine by driving an electric motor using only electric energy supplied from a charged battery cell as a power source. Electric vehicles can be eco-friendly vehicles that do not use fossil fuels and do not emit carbon dioxide or nitrogen oxides when driving. The charging cart 100a is provided with a connector (i.e., first connector) that is electrically connected to a charging port (e.g., charging connector) of the electric vehicle, and can supply power to the electric vehicle through the connector.

In an embodiment, the charging cart 100a may be provided to be movable so that it can be shared and used by multiple users within a parking space. Since the Chungcheon cart 100a includes a traveling unit, it may be able to move within a parking space where a plurality of vehicles are parked. For example, users can park their electric car in a specific area within the parking space, move the charging cart (100a) to the location where their electric car is parked, and connect the first connector of the charging cart (100a) to the electric car. By supplying power, charging of the electric vehicle can be performed.

According to one embodiment, the charging cart 100a may be an electric cart that can be moved with electric assistance to reduce the force for movement, that is, the user's labor. In general, a cart for charging an electric vehicle may be provided with a somewhat high weight (e.g., about 700 kg) as it is constructed through a combination of a charging module (e.g., an energy storage device) and electronic elements for the same. In this case, a lot of force may be required for the user to move the cart to the location where the user's vehicle is parked. In particular, if there is an uphill road, downhill road, or speed bump on the movement path of the charging cart 100a, more user force may be required to move the charging cart 100a, so movement of the cart 100a may be required. Control can be difficult. If there is difficulty in controlling the movement of the charging cart 100a, it may cause stability problems. For example, in a situation where the user is leading the charging cart 100a and moving downhill, if the user's body (e.g., hand) holding the charging cart 100a is separated, the charging cart 100a If sensing information related to a stop cannot be detected immediately, it can cause serious stability problems.

The charging cart (100a) of the present invention can assist the movement of the charging cart (100a) by detecting the user's operating intention through various sensor modules. For example, when a user wants to move the charging cart 100a to charge his or her electric vehicle, the user's intention to move the charging cart 100a is determined through various sensors provided on the charging cart 100a ( For example, it is possible to determine whether the cart is being pushed or stopped, etc., and to provide power to the charging cart 100a in response to this, thereby controlling the movement of the charging cart 100a with a small amount of force.

In a further embodiment, the charging cart 100a may include an automated robot cart that identifies the location of a parked electric vehicle, approaches the location of the identified electric vehicle, and performs charging. In this case, the user can transmit a signal calling the charging cart 100a to a server (e.g., automated robot management server, parking lot management server, etc.) using a user terminal (e.g., smartphone, tablet, PDA, laptop, etc.). there is.

For example, a parking lot may be divided into a plurality of parking areas, and a smart tag (eg, NFC tag) matching the plurality of parking areas may be provided (eg, attached to a pillar). The user can transmit a signal to call the charging cart 100a to the server by selecting the NFC tag located in the parking area of the electric vehicle using the user terminal.

Meanwhile, the server may have a parking lot mapped based on a drawing of the building. The server can specify the parking area for the electric vehicle in the mapped parking lot according to the signal received from the user terminal, and can transmit a control command to the charging cart 100a to move the charging cart 100a to the specified parking area. there is. According to this process, the charging cart 100a of the present invention can move from the waiting position to the electric vehicle parking area through autonomous driving. Additionally, the charging cart 100a can identify the location of the charging connector of the electric vehicle, dock the first connector 100 to the identified charging connector, and then charge the electric vehicle. For example, the charging cart 100a of the present invention may be equipped with a short-distance position sensor, and the short-distance position sensor can sense the position of a charging connector (eg, a second connector) in the vicinity of the electric vehicle. The charging cart of the present invention can charge an electric vehicle through a process of transferring electric energy from an electric energy storage device to the electric car.

According to one embodiment of the present invention, the charging cart 100a can move to the charging station after completing charging the electric vehicle. For example, the charging cart 100a may be moved to the charging station based on force applied from the user (eg, force for manipulating the cart) or through a traveling signal (eg, return signal) received from the server. Here, the charging station may refer to an area for charging electric energy in the electric energy storage device of the charging cart 100a. As the charging cart 100a supplies electric energy to the electric vehicle, the electric energy stored in the electric energy storage device of the charging cart 100a may be consumed, and the consumed electric energy can be recharged through a charging device provided at the charging station. It can be. In other words, the charging station may mean an area for charging the charging cart 100a, which moves to a location where the electric vehicle is parked and performs charging.

According to one embodiment of the present invention, the second connector 200 may be provided in the charging device 200a. The charging device 200a in the present invention may include a battery charging device related to an electric vehicle or a charging device provided in a charging station for charging the charging cart 100a. Depending on the embodiment, the second connector 200 may be a charging connector related to an electric vehicle or may include a charging connector related to a charging device provided in a charging station. Charging stations are a concept that includes both fixed and mobile types.

In other words, docking (or connection) between the first connector 100 and the second connector 200 in the present invention involves connecting the charging cart 100a and the electric vehicle for charging the electric vehicle and charging the charging cart 100a. And it may be related to the connection between the charging cart 100a and the charging device 200a for power transmission.

Generally, in order to charge an electric vehicle through the charging cart 100a related to a mobile charging device, a separate connector for electrical connection may be required. That is, the connector (e.g., first connector) provided in the charging cart 100a is connected to the charging device (e.g., energy storage device or battery) of the electric vehicle and can serve as an electrical/physical bridge to transfer electrical energy. . In the process of transmitting electrical energy through a connector, if the connection of the connector is incomplete, there is a risk of safety hazards such as breakdown and fire. In this case, since the amount of power supplied per hour through the connector is quite large, a significant risk to stability may occur. For example, if a slight positional error occurs between the charging cart 100a and the electric vehicle charging device 200a, a malfunction or fire may occur due to poor coupling, which may result in material and human damage.

In order to prevent the above problems from occurring, the present invention provides a docking connector that improves electrical/physical bonding by correcting positional errors even when positional errors between the two devices occur during the docking process of the connector for charging. Assembly can be provided. A description of the specific structural features, configuration, and effects of the docking connector assembly of the present invention will be described below with reference to FIGS. 2 to 8.

Figure 2 is an exemplary diagram illustrating a coupling process of a first connector and a second connector included in a docking connector assembly related to an embodiment of the present invention. Figure 3 shows an exemplary view of a first connector related to an embodiment of the present invention as viewed from the side. Figure 4 shows an exemplary view of a second connector related to an embodiment of the present invention viewed from various directions. Figure 5 shows an exemplary view of a second connector related to an embodiment of the present invention viewed from one direction. Figure 6 shows an exemplary diagram for explaining the coupling process of the first connector and the second connector related to an embodiment of the present invention. Figure 7 is an exemplary diagram illustrating a first spring part and a second spring part provided in a second connector related to an embodiment of the present invention. Figure 8 is an exemplary diagram showing that the position of the second connector related to an embodiment of the present invention can be adjusted in multiple directions.

According to one embodiment of the present invention, the docking connector assembly 1000 is composed of a first connector 100 and a second connector 200, as shown in FIG. 2, and the first connector 100 and the second The connector 200 corresponds to a coupling assembly that can be electrically and physically coupled. In one embodiment, the first connector 100 may be provided on a movable body, and the second connector 200 may be provided on either a movable body or a fixed body. However, the second connector 400 is often installed on fixtures such as fixed charging devices and pillars.

For example, the first connector 100 is provided on the charging cart 100a that is moved to charge the electric vehicle, and the second connector 200 is provided on the electric vehicle connected to the charging cart 100a for charging the electric vehicle. It can be. For another example, the first connector 100 is provided on a charging cart 100a that is moved for charging an electric vehicle, and the second connector 200 is provided on a charging station for charging the charging cart 100a. It may also be provided in the device 200a. The detailed description of the device provided with each of the above-described first and second connectors is only an example, and the present invention is not limited thereto. In an embodiment, the first connector 100 and the second connector 200 may be docked (or connected) for charging an electric vehicle, and as the first connector 100 and the second connector 200 are connected, The electrical energy stored in the charging cart 100a is transferred to the electric vehicle, so that the charging device for the electric vehicle can be charged. That is, the transfer of electrical energy may be possible through the connection between each connector.

According to one embodiment of the present invention, the first connector 100 may be provided to be movable, such as protruding outward from the charging cart 100a. According to an embodiment, the docking terminal (eg, first docking terminal) of the first connector 100 that is physically/electrically connected to another device and transmits electrical energy may need to be protected from external shock or foreign substances. Accordingly, when not in use (e.g., when not connected to the second connector for charging), it is located in a protected position through the external surface, and when in use (e.g., when connected to the second connector for charging) It may protrude and be connected to the second connector 200.

Specifically, referring to FIG. 3 , the first connector 100 may include a first moving part 110, a motor 120, and a docking part 130. The motor 120 can generate driving force, and the first moving unit 110 serves to control the position of the docking unit 130 based on the driving force generated by the motor.

According to one embodiment, the motor 120 refers to equipment that converts electrical energy into mechanical energy by using the force received by a current-carrying conductor in a magnetic field, and is characterized by generating a driving force through the generated mechanical energy. can do. Meanwhile, in addition to motors, other types of power transmission devices, such as hydraulic cylinders, may be used.

According to one embodiment, the first moving unit 110 may receive power generated from a motor (or power transmission device) and control the movement of the docking unit 130 based on the power. More specifically, the first moving part 110 is capable of moving on the first guide rail 111 by the power generated from the first guide rail 111 and the motor 120 provided along the longitudinal direction corresponding to a specific axis. It may include a first movable body 112. As shown in FIG. 3, the first movable body 112 can move on the first guide rail 111 by the driving force of the motor 120. Here, the movement radius of the first movable body 112 on the first guide rail 111 may be limited through the first movement limit surface 111-1 and the second movement limit surface 111-2. . That is, the first movable body 112 can be moved on the first guide rail 111 between the first movement restriction surface 111-1 and the second movement restriction surface 111-2 by the driving force of the motor. there is.

According to one embodiment, the docking unit 130 is a docking terminal (e.g., a first docking terminal) directly connected to a docking terminal (e.g., a second docking terminal) of the charging device 200a related to a mobile or fixed body. may include. If the docking terminal of the docking unit 130 is exposed to the outside, there is a risk of electric shock occurring, so it needs to be safely protected when not in use. That is, the docking unit 130 of the present invention may be allowed to move in one axis direction depending on whether it is used or not. For example, the docking unit 130 may be moved to a first position where it protrudes, or may be moved to a second position where it is protected inward.

Specifically, the docking unit 130 may be provided connected to the first movable body 112, as shown in FIG. 3. Accordingly, it can be moved together with the movement of the first movable body 112. Specifically, as the first movable body 112 moves in the direction of the first movement limit surface 111-1 on the first guide rail 111 by the driving force of the motor 120, the docking unit 130 is externally moved. It can be moved to the first position where it protrudes. That is, when it is intended to connect the first docking terminal 132 of the first connector 100 with the second connector 200, the first moving body 112 is moved to the first movement limit surface by the driving force of the motor 120. It can be moved in the (111-1) direction, and the docking portion 130 connected to the first movable body 112 is moved together and protrudes outward, thereby enabling connection with the second connector 200. In one example, when charging is completed through connection between the first connector 100 and the second connector 200, the first moving body 112 is connected to the second movement limit surface 111- 2) direction, and accordingly, the docking unit 130 connected to the first movable body 112 moves together and can be moved to a second position protected inside the first connector 100.

The docking unit 130 including the first docking terminal 132 is usually located in a second position protected by the exterior of the first connector 100, but when it is intended to be combined with the second connector 200, It may move according to the movement of the first movable body 112 based on the driving force of the motor and protrude outward from the first connector 100. That is, as the docking unit 130 is provided through a mechanism that can move in one axis direction (eg, the y-axis direction in FIG. 2), stability problems that may occur when not in use can be prevented. In other words, when not in use (e.g., when not connected to the second connector for charging), the docking unit 130 is located in the second position protected by the exterior of the first connector 100, thereby preventing various types of damage, such as electric shock or device damage. The first docking terminal can be protected from accidents.

According to one embodiment, the docking unit 130 may include a docking guide 131. The docking guide 131 may guide the coupling position so that the first docking terminal 132 is coupled to one position of the second connector 200. For example, since the connection between each connector is based on high-voltage electrical energy transfer, accurate connection is required, and it must be robust even after accurate connection and even when external shock occurs. The second connector 200 may include a central hole 232-1a through which the docking guide 131 passes, and the docking guide 131 is positioned around the central hole 232-1a. A guide hole 232-1 may be provided to guide movement in the -1a) direction. The docking guide 131 can easily penetrate the central hole 232-1a through the guide hole 232-1, thereby improving convenience. In addition, when coupling each connector, the docking guide 131 of the first connector 100 penetrates the center hole 232-1a of the second connector 200, thereby protecting the coupling between each connector from external shock. can do. For a specific example, referring to FIG. 6, as the two docking guides 131 are inserted to penetrate each of the two central holes 232-1a, the first docking terminal 132 provided between each docking guide ) may be combined with the second docking terminal (232-2). In this case, a docking guide 131 may be provided by being inserted into the central hole 232-1a in the upper and lower directions of the coupled docking terminals, respectively. Accordingly, the coupling fixing force is improved, and when an external shock occurs, the generated shock is dispersed and the shock directly applied to the coupled docking terminals is reduced, thereby improving stability. That is, the docking guide 131 provided in the docking unit 130 facilitates coupling between each connector, and after coupling, the effect of strengthening the coupling between connectors can be provided.

In an embodiment, the length of the first guide rail 111 may be longer than the length of the docking guide 131. When the docking unit 130 is located in the second protected position on the inside, this may be to prevent the docking guide 131 from being exposed to the outside. That is, since the length of the first guide rail 111 is longer than the length of the docking guide 131, when the docking unit 130 is located in the second position, the docking guide 131 is positioned outside the connector (e.g., may not deviate from an imaginary line extending from the first movement restriction surface.

According to one embodiment, the second connector 200 may be provided in the form of a structure capable of multi-axis movement and rotation for smooth coupling with the first connector 100. Specifically, the second connector 200 can move in more than one axis direction and can be rotatable about any axis. For example, with reference to FIG. 2, the second connector 200 may be provided to be movable in the z-axis direction and the x-axis direction, and may be provided to be rotatable about the z-axis. there is. More specific features related to the second connector 200 will be described later.

According to the embodiment, the second connector 200 may include a fixing part 210, a second moving part 220, and a rotating part 230. In one embodiment, the second connector 200 may include a fixing part 210 provided on one side of the charging device 200a. The fixing part 210 may be provided with a mechanism for adjusting the height of the second docking terminal 232-2.

Specifically, the fixing part 210 may include two supports 211, a fixing rail 212, and a height movable body 213. The fixing part 210 may include two supports 211 provided at regular intervals in the vertical direction. Here, the vertical direction may be related to the z-axis direction in FIG. 2. As shown in FIG. 4, the two supports 211 may be provided in a direction perpendicular to the ground. Additionally, the fixing part 210 may include a fixing rail 212 connecting the two supports. The fixed rail 212 may be provided to be perpendicular to the ground. Additionally, the fixing part 210 may include a height movable body 213 that can move in the vertical direction on the fixing rail. That is, the height movable body 213 can be moved in the up and down directions on the fixed rail.

According to the embodiment, the second moving part 220 and the rotating part 230 may be connected to the fixing part 210. Specifically, the second moving part 220 and the rotating part 230 may be connected to the height movable body 213 of the fixing part 210. Accordingly, the second moving part 220 and the rotating part 230 may be able to adjust their positions in the height direction according to the movement of the height moving body 213. For example, as the height movable body 213 moves downward on the fixed rail 212, the height of the second moving part 220 and the rotating part 230 may be lowered, and the height movable body 213 moves downward on the fixed rail 212. As it moves upward on (212), the height of the second moving part 220 and the rotating part 230 may increase.

This can become possible. For a specific example, when the installation position of the second connector 200 is higher or lower than the installation position of the first connector 100, the height of the rotating part 230 is adjusted by moving the height moving body 213. The position of the docking terminal of each connector can be aligned. In other words, as position correction according to height becomes possible, the stability of the combination can be improved.

In one embodiment, the second connector 200 may include a second moving part 220 connected to the fixing part 210 so as to be movable in the horizontal direction with respect to the fixing part 210.

The rotating body 232 connected through the fixed axis 231-1 related to the z-axis direction may be rotatable based on the z-axis direction of the second fixed body 231. Since the rotating body 232 may be provided with a second docking terminal 232-2 for coupling with the first connector 100, the rotating body 232 is rotatably provided with a second docking terminal ( This may mean that 232-2) is provided to be rotatable in response to the second fixed body 231 (or in relation to the z-axis direction).

That is, the second docking terminal 232-2 of the second connector 200 of the present invention moves with respect to each of the two axes (e.g., x-axis and z-axis) directions for smooth coupling with the first connector 100.

Accordingly, the second moving part 220 and the rotating part 230 may be able to adjust their positions in the height direction according to the movement of the height moving body 213. For example, as the height movable body 213 moves downward on the fixed rail 212, the height of the second moving part 220 and the rotating part 230 may be lowered, and the height movable body 213 moves downward on the fixed rail 212. As it moves upward on (212), the height of the second moving part 220 and the rotating part 230 may increase.
