Technical Field

The present subject matter relates generally to vehicles. The present subject matter relates particularly, but not exclusively, to vehicle charging ports in three-wheeled vehicles.

Background

Three-wheeled motor vehicles are an important tool for public transportation and cargo transportation in developing countries. In rural and urban areas, it is widely used as a point-to-point vehicle, also known as an automated human powered vehicle. In general, motor vehicles have a driver's compartment in the front and a passenger loading compartment or platform in the rear. For passenger vehicles, the rear compartment includes a passenger seat. The vehicle may have one or more energy sources, such as a lithium ion main battery and an auxiliary battery that power the vehicle. The driver operates the vehicle from the first compartment. A driver seat is provided in the front compartment so that the driver operates the vehicle in a sitting position. Suspension structures for three-wheeled vehicles often employ independent trailing arms with rear suspension systems to support the vehicle body on two rear wheel assemblies. Furthermore, a storage compartment provided behind the rear seat of the vehicle provides space for storage of cargo. In some vehicles, the rear of the vehicle has a trailer storage space in the form of a cabin to carry cargo.

Detailed Description

Over the years, the transportation related technology has undergone tremendous revolution, such that current focus has been on manufacturing efficiency and costs, including material costs, assembly costs, inventory handling costs, and the like. At the same time, there is a need in the industry for stronger, smaller, economically advantageous vehicles that consume less power. The vehicle driven by the power storage device is just eco-friendly, and accords with the green and environment-friendly advocates of various organizations. These vehicles may be two-wheeled, three-wheeled or four-wheeled, depending on the consumer's requirements, and have a variety of applications.

In the automotive industry, electric vehicles are introduced to control air pollution caused by vehicles driven by IC engines. Currently, electric vehicles are classified into two types, namely, pure electric vehicles and extended range electric vehicles (also referred to as hybrid vehicles). A hybrid vehicle has a main electric drive with an associated energy storage device and an internal combustion engine coupled to an electric motor/generator.

In recent years, hybrid vehicles and electric vehicles have become quite popular due to the high oil prices of pure gasoline fuel-consuming vehicles and their impact on the environment. Hybrid vehicles have become an intermediate choice for consumers who wish to reduce fuel consumption while increasing their allowable travel distance, particularly in comparison to electric-only vehicles (EVs). In the market of most developing and less developed countries, low cost tricycles are often used as a common public or cargo transportation vehicle. For a passenger layout, the rear of the vehicle is configured with a passenger seating compartment, while for a cargo transporter, the rear has a loading trailer platform layout to carry cargo. Unlike conventional four-wheeled vehicles, three-wheeled vehicles are a compact, lightweight and economical means of transportation.

Typically, such multi-track vehicles have a steering axis arranged centrally along a longitudinal mid-plane of the vehicle, with the rider being coaxially seated in the same mid-plane. Such vehicles are typically powered by IC engines, and electrification of mass transit vehicles is important to reduce emissions. Any significant changes or modifications to the vehicle to accommodate different powertrains for a given product are undesirable due to adverse effects on manufacturing complexity, vehicle model, logistics, supply chain challenges, and cost. Manufacturers often prefer platform product solutions where the basic structure of the vehicle may be generic among the powertrain types used. This provides the manufacturer with great flexibility to be able to operate with different powertrains, such as IC engines or hybrid systems, on different markets, different models, etc. of standardized product platforms, but depending on the specific requirements.

DC powered electric vehicles use different types of batteries, but all of these batteries need to be charged from time to time in order to run the vehicle again after the battery is discharged. The battery in the vehicle may be charged by an off-board charger that supplies DC power to the vehicle battery and communicates with the vehicle controller to determine the amount of voltage and current required to power the battery. The off-board charger is disposed outside the body of the vehicle, for example, in a charging station that can provide different levels of power to charge the batteries of different vehicles depending on the load. The charging process of off-board systems can be very cumbersome because many times the vehicle may run out of power and the vicinity may not have a charging station, which can lead to the vehicle being stuck in the middle of the road. The in-vehicle charger unit overcomes the problems associated with off-vehicle chargers. With an on-board charger, the vehicle may be connected to any electrically available charging point, including the home, and thus not rely on the public infrastructure of charging stations with off-board charging capabilities.

However, in order to provide additional components, such as an on-board charger, in a compact vehicle, such as a closed three-wheeled vehicle, it is necessary to provide a charging port that can charge an energy storage device, such as a battery, in an easy, convenient and quick access location, while ensuring protection from environmental damage, tamper resistance, and dust and mud resistance. The charging port should be located where it is easy to access the charging port while also ensuring that the charging port is not in direct contact with any external environmental factors. Moreover, the charging port undergoes the process of plugging and unplugging the charging plug of the charging station, so the charging port needs to be installed in a manner that does not fall off, or to remain protected from any direct impact on the body of the vehicle that would damage the charging port. Accordingly, there is a need for an improved charge port layout scheme for a three-wheeled vehicle that overcomes all of the above-described problems, is capable of designing a compact vehicle layout, and overcomes the problems associated with known techniques.

It is therefore an object of the present invention to provide charging port installation and positioning in a three-wheeled vehicle that overcomes the above-mentioned problems. The present invention provides a charging port mounted in one or more locations in a three-wheeled vehicle that is easily accessible for charging an energy storage device, such as a battery. In one embodiment, the charging port is mounted on at least one housing panel of a cabin assembly of the vehicle by a charger stand. By providing the charging port on at least one housing panel of the cabin assembly, it is possible to arrange the charging port closer to an energy charging device such as a battery, which is generally mounted at the rear of the vehicle, such as under the passenger seat of the vehicle, and to a frame member of the chassis of the vehicle, thereby reducing the harness length, improving the convenience of coupling the charger, and eliminating harness loss. Incorporating the charger stand enables the charging port to be mounted on the housing panel while providing protection against any shock, for example during an accident or tipping of the vehicle. The charger stand is fixedly mounted on the at least one housing panel and then the charging port is securely arranged on the charger stand such that the charger stand both provides support for the charging port and maintains the charging port away from direct contact of the housing panel with the charging port, which helps to prevent any damage that may occur due to any undesired impact suffered by the housing panel.

Another embodiment of the invention provides a configuration of a charging port on at least one housing panel of a cabin assembly of a vehicle, wherein the housing panels include a right hand side housing panel, a left hand side housing panel, and a rear housing panel. The right hand side housing panel, the left hand side housing panel and the rear housing panel form a cabin assembly that encloses the vehicle from three directions to provide protection against environmental factors such as wind, dust and water. The charging port is mounted on an inner surface of the cabin assembly.

Yet another embodiment of the present invention provides a configuration of the charging port on the housing panel of the cabin assembly by a charger stand. The charger stand includes a charging port mounting surface having the contour of a circular hollow disk (although this should not be considered as the only limitation). The charger stand accommodates the charging port, and a charging port mounting surface of the charger stand is complementary to the shape of the charging port. Further, the charging port mounting surface is fixedly supported on a pair of attachment plates. The charging port mounting surface forms a charger stand along with the attachment plate. The charging port mounting surface is arranged substantially perpendicular to the attachment plate such that the charging port mounting surface is parallel to the surface of the right-hand side housing panel (housing panel). A base member fixedly attached to the attachment plate. The bottom member of the charger stand provides the necessary support for the charging plug or gun and also enhances the charger stand by providing support from the bottom to the charging port, which prevents the charging port from being displaced from its intended position due to the continued plugging of the charging plug connected to the charging station.

Another embodiment of the present subject matter provides an opening or cutout made in the housing panel. The diameter of the charging port mounting surface is substantially equal to the width of the opening. The width of the opening is sufficient to allow insertion of the charging plug from the outside so as to connect the charging plug led out from the charging station into the charging port. It is necessary to keep the charging port away from direct contact with dust or water molecules, and therefore an access device such as a hinged door is provided on the opening of the housing panel. Further, a door lock may be provided for the access device to limit unauthorized access to the charging port.

Yet another embodiment of the present subject matter provides for the construction of the charging port on the charger stand through the adapter plate. The adapter plate forms part of the charging port. The adapter plate is provided with one or more perforations allowing one or more fasteners to enable the charging port to be mounted on the charging port mounting surface of the charger stand. The adapter plate is complementary to the shape of the charging port mounting surface of the charger stand to eliminate the effect of vibration on mounting the charging port on the charger stand and to eliminate the shock caused by the insertion and extraction of the charging port from the charging station.

Fig. 1 and 1a show side and rear views of a motor vehicle (100), fig. 2 is a perspective view of a frame structure of the motor vehicle according to an embodiment of the present subject matter. In one embodiment, a frame structure (200) of a motor vehicle includes three cabins. The front compartment comprises a head pipe (201), a main pipe (206), a driver seat assembly (104), and a pair of LH side frame members (205) and RH side frame members (202), wherein the head pipe (201) mounts a handle assembly (106) of the motor vehicle and is capable of steering a front wheel (101), the main pipe (206) connects the head pipe (201) and the center frame member (203), and the driver seat assembly (104) is accommodated on top of the center frame member (203). The motor vehicle further comprises a pair of rear wheels (102) and a front fender (103) arranged above the front wheels (101). A CNG cylinder or the like is housed in a housing area (110) below the operator's seat assembly (104). In one embodiment, the frame structure (200) further includes a middle compartment including a passenger seat assembly (108) consisting of a seat base bottom and a backrest, a passenger barrier (107) to restrict entry/exit of a passenger into/from the three-wheeled vehicle in only one direction, a connecting bridge member (204) to which the passenger seat can be mounted. Further, in one embodiment, the frame structure further comprises a rear compartment accommodating a cabin assembly (109) extending circumferentially around said rear compartment and a power unit, such as an engine (111), which power unit together with the transmission unit is arranged to be placed substantially at the rear side of the motor vehicle (fig. 1 a). In another embodiment shown in fig. 2a, the motor is disposed in a motor mounting area (216) between a pair of rear wheels (102).

Further, according to one embodiment of the invention, a pair of rear frame members (214) extend upwardly from the left-hand side frame member (205) and the right-hand side frame member (202) and further extend horizontally to the rear of the vehicle (100). The pair of rear frame members (214) includes a left frame member (213) and a right frame member (212) that extend horizontally to the rear of the vehicle. The left (213) and right (212) frame members are connected by a plurality of connecting bridges arranged longitudinally (210, 211) and transversely (204, 208, 209), ensuring a rigid attachment of the frame members. Furthermore, in one embodiment, a harness (cable) routing/guiding bracket (not shown) is mounted on a laterally arranged connection bridge (209). In an alternative embodiment, the wire harness guide brackets can be welded to a vertical structural member that is connected to a laterally arranged connection bridge (209). Typically, in three-wheeled electric vehicles, multiple bundles of cables are routed between subsystems. The harness guide bracket ensures better guidance and prevents the harness from being damaged by interfering with adjacent components of the vehicle.

The pair of rear frame members (214) provide housing members for various electrical components, such as controllers, motors, and the like. The controller (215) shown in fig. 2a is mounted with a mounting bracket assembly (217) located between the pair of rear frame members (214), between the pair of connecting bridges (204, 208) (as shown in fig. 2 a), and below the passenger seat assembly (108). According to one aspect of the invention, the interface surface of the controller (215) faces upwards, ensuring easy assembly and easy access of the connection lines. The area above the controller is covered with a first metal sheet or cover (219) (as shown in fig. 2 b). Further, the metal sheet or cover is provided with a top opening (as shown in fig. 2 b) with a locking mechanism (220). When the passenger seat (108) is removed, the locking mechanism (220) is accessible from the top of the first sheet metal or cover (219), ensuring limited and authorized access to the controller, and also ensuring easy access to the controller during maintenance. According to another aspect of the present invention, electrical components such as controllers, motors, etc. are placed between the pair of rear frame assemblies (214) and parallel to each other, thereby reducing the length of electrical wires required to route and connect each component. The reduction in wire length also ensures a reduction in voltage drop and avoids undesirable bending of the wire, thereby improving the efficiency of the electrical component.

According to one embodiment of the invention, an energy storage device (218) (shown in FIG. 2 a) is mounted in front of the connection bridges (204) or at least partially overlaps any one of the connection bridges. The connecting bridge (204) is arranged transversely to the vehicle. The energy storage device (218) is mounted with a mounting bracket (207) having an L-shaped profile, which is arranged vertically downward with respect to the connecting bridge (204) and is accommodated under the passenger seat (108). The mounting bracket (207) is integrally attached to the front of the connection bridge (204) and accommodates the auxiliary energy storage device (218) therein, ensuring that the energy storage device is mounted to the front of the connection bridge without extending outwardly from the passenger seat in a front-to-rear direction. This configuration also ensures that the installed energy storage device does not interfere with the legs of the occupant and thus does not compromise the comfort of the user. According to one embodiment, the energy storage device may be located below the operator's seat. According to one embodiment, the energy storage device in the form of a battery array is arranged using support columns, clamps and base plates, which allows for easy replacement of the batteries compared to top mounting.

Fig. 3a shows a top view of the vehicle (200). A charging unit (600) for charging an energy source, such as a battery, is disclosed. The connection bridge member (204) capable of mounting the driver's backrest also enables mounting of the charging unit (600). The charging unit (600) may be installed to face in a direction opposite to a face of the passenger seat. The passenger seat is located on a front side of the connection bridge member (204) facing a front of the vehicle (100) when viewed from the top, and the charging unit (600) is mounted on a rear side of the connection bridge member (204) facing a rear of the vehicle (100) when viewed from the top. Further, the controller (215) is located near the charging unit (600) and the charging port (800). The charging unit (600) may be mounted on either the left hand side or the right hand side of the controller (215) and such proximity to the controller (215) and the energy storage device (218) reduces the length of the harness.

Further, a charging port (800) is connected to the charging unit (600) for charging an energy storage device (218), such as a battery. A charging port (800) is mounted on the cabin assembly (109). The cabin assembly (109) includes one or more housing panels, such as a right-hand housing panel (109 a), a left-hand housing panel (109 b), and a rear housing panel (109 c). The charging port (800) is mounted on at least one housing panel of the cabin assembly (109). The charging port (800) is connected to a charging unit (600) to provide AC power, the charging unit being a vehicle-mounted charging unit (800) to convert the AC power to DC power for transmission to a battery for charging.

Fig. 4a shows a side view of the vehicle (100). In order to protect the charging port (800), an access device (801) is provided. The access device (801) prevents any exposure to environmental factors such as dust or water and keeps the charging port (800) from any damage.

Fig. 4b shows a side view of the vehicle (100) to depict an embodiment in which the charging port (800) is mounted beneath the operator's seat assembly (104) and the power storage housing area (110).

Fig. 5 shows a left hand side housing panel (109 b), which may also be the right hand side housing panel (109 a) of the cabin assembly (109). The charging port (800) includes a socket body (808) and an adapter plate (802). To mount the charging port (800) on a housing panel such as a right-hand side housing panel (109 a); a charger stand (804) is provided. Since the charging port (800) is directly mounted on the case panel, the charging port (800) is easily damaged by impact to the charging port (800). Thus, the charging port (800) is mounted on the housing panel by the charger stand (804). The charger stand (804) includes a charging port mounting surface (804 b) having a circular hollow disk profile, although the profile is not a limitation, as the charger stand (804) accommodates the charging port (800) and the charger stand (804) is complementary to the shape of the charging port (800). Further, the charging port mounting surface (804 b) is fixedly supported on a pair of attachment plates (804 a). The charging port mounting surface (804 b) forms a charger stand (804) along with the attachment plate (804 a). The charging port mounting surface (804 b) is arranged substantially perpendicular to the attachment plate (804 a) such that the charging port mounting surface (804 b) is parallel to the surface of the left hand side housing panel (109 b) (including other housing panels of the cabin assembly). Further, the length of the attachment plate (804 a) is substantially equal to the length of the charging port (800). The charging port mounting surface (804 b) is arranged at a predetermined distance from the housing panels (109 a, 109b, 109 c).

The charging port (800) is fixedly connected to the right-hand side housing panel (109 a). An opening (805) is made in the right-hand side housing panel (109 a) by cutting the left-hand side housing panel (109 b a). The diameter of the charging port mounting surface (804 b) is substantially equal to the width of the opening (805). The width of the opening (805) is sufficient to allow insertion of the charging plug from the outside so as to connect the charging plug into the charging port (800). It is necessary to keep the charging port (800) away from direct contact with dust or water molecules, and therefore an access device (801), such as a hinged door, is provided on the opening (805) of the left hand side housing panel (109 b). The access device (801) may further be provided with a door lock (807) to limit unauthorized access to the charging port (800). The charging port (800) is mounted on the charger stand (804) through the adapter plate (802). The adapter plate (802) forms part of the charging port (800). The adapter plate (802) is provided with one or more perforations allowing one or more fasteners (806) to enable the charging port (800) to be mounted on the charging port mounting surface (804 b) of the charger stand (804). The adapter plate (802) is complementary to the shape of the charging port mounting surface (804 b) of the charger stand (804) to eliminate the effect of vibration on the mounting of the charging port (800) on the charger stand (806) and to eliminate the impact caused by the insertion and extraction of the charging port (800) from the charging station.

A charging port (800) is provided on a housing panel of a cabin assembly (109), which facilitates charging a battery located at the rear of a vehicle (100), and also reduces the distance between the battery and the charging port (800), thereby reducing the harness length. If the charging port (800) is mounted on the left hand side housing panel (109 b), the battery may be located near the left hand side housing panel 109 b. Similarly, if the charging port (800) is mounted on the right-hand side housing panel (109 a), the battery may be located near the right-hand side housing panel (109 b).

Fig. 5a shows an enlarged view of a charger stand (804) with a bottom member (803). The base member (803) provides support for the charging port (800) and the charging plug from the charging station. When the plug-in process of the charging port (800) is performed, the charging port (800) moves in the up-down direction, which causes loosening of the charging port (800) with time. Thus, the bottom member (803) incorporated in the charger stand (804) can eliminate such unnecessary movement and prevent any damage to the installation of the charging port (800). Fig. 6 shows an exploded view of the charging port (800) mounted on the charger stand (804) from a top view. The charging port axis (LL ') is substantially perpendicular to the plane axis (PP'). The charger stand (804) is also arranged on the housing panel perpendicular to the plane axis (PP'). The plane axis (PP') is an axis substantially parallel to the surface of the housing panel. The charging port axis (LL') passes through the center of the charging port (800).
