The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
The invention will be illustrated in the following with different embodiments. It should be noted that the elements described in the following embodiments may be implemented in hardware (e.g., circuitry or machinery), or implemented in combination with software (e.g., a program written in a processor). In addition, in the following embodiments, the car is taken as an example, but the car may be replaced by other devices that need to be charged. In addition, two light emitting elements are described below, but the number of light emitting elements may be other.
Fig. 1 is a schematic diagram of a charging system according to an embodiment of the invention. FIG. 1 shows a plurality of parked cars C _1, C _2, C _3, and C _ 4. In the following embodiment, only the car C _1 is used for illustration, but the cars C _2, C _3, and C _4 may all adopt the same mechanism. The car C _1 is provided with a guiding device 101 thereunder, and the guiding device 101 comprises light emitting elements L _1 and L _ 2. The charging device 100 moves to the charging position according to the light emitting states of the light emitting elements L _1 and L _2 to charge the vehicle C _ 1. How the charging device 100 charges the automobile C _1 according to the light emitting states of the light emitting elements L _1, L _2 will be described below in different embodiments.
Fig. 2 to 6 are schematic diagrams illustrating operations of a charging system according to an embodiment of the invention. As shown in fig. 2, in an embodiment, the charging device 100 includes a front camera R _1 and a top camera R _ 2. The step of moving the charging device 100 to the charging position of the vehicle according to the light emitting states of the light emitting elements L _1 and L _2 comprises: the front camera R _1 is moved to a temporary position (as shown in FIG. 2) according to the positions of the light emitting elements L _1 and L _ 2; then, the upper camera R _2 is moved from the temporary position to the charging position (as shown in fig. 3) according to the lighting pattern of the light emitting elements L _1 and L _ 2. The light emitting pattern of the light emitting elements L _1, L _2 may comprise at least one of the following information: the arrangement of the light emitting elements, the shape of the light emitting elements themselves, or the frequency of light emission. Specifically, the charging device 100 determines the approximate positions of the light emitting elements L _1 and L _2 based on the positions of the light emitted by the light emitting elements L _1 and L _2 through the front camera R _1, and moves the approximate positions as temporary positions. Then, the upper camera R _2 is used to finely adjust the temporary position as a charging position according to the arrangement of the light emitting devices, the shape of the light emitting devices themselves or the light emitting frequency. In one embodiment, the temporary position is not fine-tuned, but is directly used as the charging position. In other words, the present embodiment can directly determine whether the charging device 100 is at the proper position according to the position images of the light emitting elements L _1 and L _2 captured by the upper camera R _2 for performing the subsequent charging operation.
In addition, in an embodiment, the charging device 100 further determines the electric quantity of the vehicle according to the light emitting patterns of the light emitting elements L _1 and L _ 2. As shown in fig. 4, when the light emitting frequencies of the light emitting elements L _1 and L _2 are high (i.e. continuous light emission), it indicates that the electric quantity of the vehicle C _1 is sufficient, whereas when the light emitting frequencies of the light emitting elements L _1 and L _2 are low, it indicates that the electric quantity of the vehicle C _1 is low. However, fig. 4 is only an example, and does not show that the light emitting patterns of the light emitting devices L _1 and L _2 can only be shown as fig. 4.
The light emitting pattern of the light emitting element can be used to transmit information other than electrical quantity. In one embodiment, the light pattern is used as identification information for a vehicle. Referring to fig. 1 and 5, as shown in fig. 5, the light emitting pattern of the light emitting device in the vehicle C _1 is stopped for a period of time after three consecutive short light emissions, the light emitting pattern of the light emitting device in the vehicle C _2 is stopped for a period of time after one long light emission, and the light emitting pattern of the light emitting device in the vehicle C _3 is formed by alternating long light emission and short light emission. In this way, the charging device 100 can accurately determine which vehicle needs to be charged. However, as mentioned above, the light-emitting pattern may also refer to the arrangement of the light-emitting devices, the shape of the light-emitting devices themselves, and the charging device 100 can determine which vehicle needs to be charged accordingly.
In one embodiment, the charging device can obtain the power information by means other than the light pattern. For example, the charging device may receive the charge amount information or the identification information from the vehicle through wireless communication such as RF (radio frequency).
Fig. 6 is a schematic diagram illustrating that the charging device preferentially charges the vehicle with a small amount of power. As shown in fig. 6, after the charging device 100 obtains the power information through the light emitting patterns of the light emitting elements L _1 and L _2 or other manners, it preferentially charges the vehicle C _1 with less power. Therefore, when a plurality of automobiles need to be charged, the automobiles with less electric quantity can be charged preferentially, so that each automobile can be ensured to run normally.
Fig. 7 is a schematic diagram of a guiding device according to an embodiment of the invention. As shown in fig. 7, the guiding device 700 includes a cover 701. When the vehicle is in a normal mode (e.g., the vehicle is in a driving state), the cover 701 is in a closed state, so that the light emitting devices L _1 and L _2 or other devices (such as a light emitting device controller) of the guiding device 701 are not polluted by dust or sewage while the vehicle is driving. When the vehicle is in a standby mode (for example, the vehicle is not in a start state), the cover 701 is in an open state, so that the charging device can detect the light emitted by the light emitting elements L _1 and L _ 2. In one embodiment, the vehicle includes a button that determines whether the cover 701 is opened or closed.
As mentioned above, the car can be replaced by other electronic devices, so the foregoing embodiments of fig. 1 to 6 can be briefly described as follows: a charging system, comprising: a charging device (e.g., charging device 100 of fig. 1-3); and a guiding device including at least one light emitting element (e.g., light emitting elements L _1 and L _2 in fig. 2 to 3) disposed in at least one target device (e.g., vehicle C _1 in fig. 1 to 3). Wherein the charging device moves to a charging position according to a light emitting state (e.g., a light emitting position, a light emitting pattern) of the light emitting element to charge the target device.
The light emitting element is not limited to be provided on the target device, and may be provided on the charging device. Fig. 8 is a schematic diagram of a charging system according to another embodiment of the invention. As shown in fig. 8, the light emitting elements L _1 and L _2 are disposed on the charging device 800 instead of in the guiding device 801 of the vehicle C _ 1. In this embodiment, the guiding device 801 moves the charging device 800 to the charging position according to the light emitting states of the light emitting elements L _1 and L _2 to charge the vehicle. In detail, the guiding device determines the position of the charging device according to the light emitting positions or light emitting patterns of the light emitting elements L _1 and L _2, and moves the charging device 800 to the charging position according to the determined position.
In this embodiment, a variety of methods can be used to communicate between the guiding device and the charging device 800. For example, the guiding device may communicate with the charging device 800 by wireless communication. Also, in this embodiment, the charging device 800 may also receive the power information from the vehicle through wireless communication, and the guiding device may use the structure with the cover shown in fig. 7.
As mentioned above, the car can be replaced by other devices, so the embodiment of fig. 8 can be briefly described as follows: a charging device (e.g., 800) comprising at least one light emitting element; and a guiding device (e.g., 801) disposed within a target device. The guiding device moves the charging device to the charging position according to the light-emitting state of the light-emitting element to charge the target device.
According to the embodiments of fig. 1 to 6, a charging method can be obtained, which can be applied to the charging system shown in fig. 1, the method comprising: detecting the light-emitting state of the light-emitting element; and moving the charging device to a charging position according to the light-emitting state to charge the target device. According to the embodiment of fig. 8, a charging method can be obtained, which can be applied to the charging system shown in fig. 8, the method comprising: detecting the light-emitting state of the light-emitting element; and enabling the guiding device to move the charging device to the charging position according to the light-emitting state of the light-emitting element so as to charge the target device. The detailed steps of the two charging methods are already described in the embodiments, and therefore are not described herein again.
According to the embodiment, the charger can automatically charge the target device, and can preferentially charge the target device with low electric quantity, thereby solving the problem of difficult charging in the prior art.
It should be noted that the above-mentioned charging method may be a wireless charging method, that is, when the charging device moves to a proper position, the charging device may not physically contact with the target device, but directly charge the target device in a wireless manner. Furthermore, the charging device itself may be wired to a fixed power source (e.g., to the mains), but may also itself have a power source (e.g., a battery) without a wired connection to an external power source. In addition, the charging device can also be wirelessly charged with an external power supply, so that the flexibility of the charging device can be improved, and the charging device cannot be clamped by the wire rod in the moving process.
The above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made in accordance with the claims of the present invention should be covered by the present invention.
