The height of the device body 110 can also be less than the maximum height of the vehicle to be charged, but greater than the height of the front and rear of the vehicle to be charged, so that the mobile charging device can straddle the front or rear of the vehicle to be charged to charge the vehicle to be charged, and also will not occupy additional parking areas. The width d1 of the device body 110 is greater than the width d2 of the vehicle to be charged, but the width d1 of the device body 110 should not exceed the maximum width of the parking space in the parking lot where the vehicle to be charged is located, so as to avoid occupying additional parking spaces and not affecting the normal exit of the vehicle to be charged and surrounding vehicles from the parking space, thereby greatly improving the convenience of charging.

In addition, by using the mobile charging device of the embodiment of the present invention, there is no need to install a fixed charging pile for each parking space, thus saving the construction and maintenance costs of the parking lot.

[0049] In order to further improve the charging convenience of a vehicle, the embodiment of the present invention provides another mobile charging device.

Figure 4 As shown, the charging device 1102 includes a battery 1102a and a charging gun 1102b.

[0050] The battery 1102a is electrically connected to the charging gun 1102b, the mobile system 130 and the control system 1101 respectively. The battery 1102a is arranged in the device body 110, and the charging gun 1102b is arranged outside the device body 110;

[0051] The storage battery 1102a is used to supply power to the charging gun 1102b, the mobile system 130 and the control system 1101, and the charging gun 1102b is used to connect to the charging interface of the vehicle to be charged.

[0052] Specifically, the battery 1102a stores electrical energy, which can be used to power the charging gun 1102b, the mobile system 130, and the control system 1101. In addition, other electrical devices in the mobile charging device can also be powered by the battery 1102a. The charging gun 1102b can be connected to the charging port of the vehicle to be charged. After the charging gun 1102b is connected to the charging port of the vehicle to be charged, the vehicle to be charged can be charged.

[0053] Optional, such as Figure 4 As shown, the mobile charging device also includes a mechanical arm 140 and a visual recognition device 150; the visual recognition device 150 is arranged on the mechanical arm 140, and the mechanical arm 140 is installed on the device body 110; the mechanical arm 140 is used to grab the charging gun 1102b.

[0054] The visual recognition device 150 is communicatively connected to the control system 1101, and the visual recognition device 150 is used to collect image information of the surrounding area of ​​the robotic arm 140 and send it to the control system 1101; wherein the image information of the surrounding area of ​​the robotic arm 140 includes image information of the charging interface of the vehicle to be charged; the control system 1101 is communicatively connected to the robotic arm 140, and the control system 1101 is also used to control the robotic arm 140 to grab the charging gun 1102b and connect it to the charging interface of the vehicle to be charged according to the image information of the surrounding area of ​​the robotic arm 140 when the mobile charging device is at the location of the vehicle to be charged.

[0055] The control system 1102 is also used to monitor the charging status of the vehicle to be charged. After the charging of the vehicle to be charged is completed, the robotic arm 140 is controlled to grab the charging gun 1102b based on the image information of the area around the robotic arm 140, so that the charging gun 1102b is disconnected from the charging interface of the vehicle to be charged.

[0056] Among them, the visual recognition device 150 can be a camera, through which image information of the surrounding area of ​​the robotic arm 140 can be collected, and the control system 1102 can extract image information of the charging interface of the vehicle to be charged from the image information of the surrounding area of ​​the robotic arm 140, and determine the position of the charging interface according to the image information of the charging interface, so that the robotic arm 140 can accurately find the charging interface of the vehicle to be charged and connect it.

[0057] Specifically, the control system 1101 is communicated with the robotic arm 140. When the control system 1101 moves the charging device to the location of the vehicle to be charged, the robotic arm 140 is controlled to grab the charging gun 1102b and connect it to the charging interface of the vehicle to be charged according to the image information of the surrounding area of ​​the robotic arm 140, so that the user does not need to manually connect the charging cable, but only needs to send a charging demand signal to enjoy the automatic charging service.

[0058] Optionally, the robot arm 140 and the charging gun 1102b are integrally arranged.

[0059] Specifically, the charging gun 1102b is arranged at the end of the mechanical arm 140, so that the mechanical arm 140 can directly control the position of the charging gun 1102b, and the mechanical arm 140 can directly connect and control the connection and extraction of the charging gun 1102b.

[0060] It should be noted that the mobile charging device of the embodiment of the present invention automatically moves within the venue through the control system 1101, and goes to the corresponding position according to the charging demand signal of the vehicle to be charged. After arriving, the mobile charging device stably straddles the vehicle to be charged. Then, the mechanical arm 140 is hung from the device body 110 of the mobile charging device. The mechanical arm 140 accurately finds the charging interface of the vehicle to be charged and connects through the visual recognition function of the visual recognition device 150, and starts automatic charging. During the charging process, the control system 1101 monitors the charging status of the vehicle to be charged in real time to ensure safety and stability. After charging is completed, the mechanical arm 140 is automatically retracted, and the mobile charging device moves to the next charging demand position or standby area. The mobile charging device of the embodiment of the present invention can move autonomously to the vehicle position for charging, and is not limited by the spacing between parking spaces, which greatly improves the user experience, the charging efficiency of the vehicle, and the convenience of vehicle charging.

[0061] Optionally, the height of the suspension system 120 is adjustable, and the control system 1101 is also used to control the suspension system 120 to rise when it moves to the side of the vehicle to be charged, so that the chassis height of the device body 110 is higher than the height of the vehicle to be charged.

[0062] Specifically, the height of the suspension system 120 is adjustable, so that it can cope with the charging of vehicles of different heights, so that the mobile charging device can be suitable for vehicles of different models. For example, cars, off-road vehicles and trucks can all be charged using the mobile charging device of the embodiment of the present invention, thereby improving the universality of the mobile charging device. And by lowering the height of the suspension system 120, the overall height of the mobile charging device is reduced, which facilitates the placement and transportation of the mobile charging device and saves placement space. When the control system 1101 moves to the side of the vehicle to be charged, it also synchronously obtains the height information of the vehicle to be charged, controls the suspension system 120 to rise, and makes the chassis height of the device body 110 higher than the height of the vehicle to be charged, so that the mobile charging device can straddle the top of the vehicle to be charged and charge the vehicle to be charged.

[0063] Optionally, the height of the suspension system 120 is fixed, and the chassis height of the device body 110 is higher than the height of the vehicle to be charged.

[0065] Optionally, the moving system 120 includes two tracks, and the two tracks are connected to both sides of the equipment body 110 through the suspension system 120 respectively.

[0066] Specifically, the mobile charging device moves via two tracks, so that the mobile charging device has certain off-road performance and high stability, so that it can be used in special terrains. The distance between the two tracks should be greater than the width of the vehicle to be charged, so that the mobile charging device can straddle the top of the vehicle to be charged and charge the vehicle to be charged.

[0067] Optionally, the mobile system 120 includes at least four wheels, and the suspension system 120 includes at least four suspension arms, each wheel is mounted to one end of the suspension arm, and the other end of the suspension arm is mounted to the device body 110.

Figure 3When the mobile system 120 has four suspension arms and the mobile system 120 includes four wheels, the four wheels are respectively installed at one end of the suspension arms, and the four wheels are respectively connected to the two sides of the device body 110 through the four suspension arms. The distance between two opposite wheels should be smaller than the width of the vehicle to be charged, so that the mobile charging device can straddle the top of the vehicle to be charged to charge the vehicle to be charged, so that the mobile charging device is not limited by the distance between parking spaces, does not occupy additional parking areas, and does not affect the normal exit of the vehicle to be charged and surrounding vehicles from the parking spaces.

[0069] Optionally, the wheelbases of the two opposing wheels are adjustable, and the control system is further used to control the wheelbase to be larger than the width of the vehicle to be charged when the vehicle moves to the side of the vehicle to be charged.

[0070] Specifically, the wheelbase of the two relative wheels is adjustable. The wheelbase of the two relative wheels is controlled by the control system, so that when charging vehicles of different widths, the mobile charging device can straddle the top of the vehicle to be charged, so that the mobile charging device is not limited by the spacing between parking spaces. And the wheelbase of the two relative wheels is adjustable, so that the mobile charging device can be used for vehicles of different models. For example, cars, off-road vehicles and trucks can all be charged using the mobile charging device of the embodiment of the present invention, thereby improving the universality of the mobile charging device. In addition, by setting the wheelbase of the two relative wheels to be adjustable, when the wheelbase is adjusted to a smaller size, the overall width of the mobile charging device is reduced, which facilitates the placement and transportation of the mobile charging device and saves placement space.

[0071] Optionally, the wheelbases of the two opposing wheels are fixed, and the wheelbases are greater than the width of the vehicle to be charged.

[0072] Specifically, the wheelbase of the two opposing wheels is fixed, which can improve the overall structural strength of the mobile charging device, and the wheelbase is larger than the width of the vehicle to be charged, so that the mobile charging device can straddle the top of the vehicle to be charged to charge the vehicle, so that the mobile charging device is not limited by the distance between parking spaces.

The charging device 1102 has efficient charging capability and safety protection function, and the control system 1101 can realize automatic navigation, positioning and charging control. The automatic charging mechanical arm 140 is designed and manufactured. The mechanical arm 140 should have high-precision visual recognition and positioning capabilities and a reliable connection mechanism, and can be quickly and accurately connected with the charging interface of different models of electric vehicles. In addition, a charging demand signal receiving device can also be set in the site where the mobile charging device is located. When the vehicle to be charged sends a charging demand, the signal is received by the charging demand signal receiving device and transmitted to the control system 1101 of the mobile charging device, and the mobile charging device autonomously goes to the location of the vehicle to be charged. When conducting field tests, different types of sites and vehicles to be charged are selected for testing to verify the mobility, charging efficiency, stability and adaptability of the vehicles to be charged. Based on the test results, various parts are optimized and improved to ensure that the vehicles to be charged can operate reliably in various actual scenarios.

[0074] In addition, the mobile charging device of the embodiment of the present invention combines a high chassis design with an ultra-high suspension, so that the mobile charging device can stably straddle the top of the vehicle to be charged to achieve automatic charging, which is the key to solving the problem of charging convenience; the design of the automatic charging mechanical arm 140, and the positioning of the charging port of the vehicle to be charged by a visual recognition device 150 with high-precision visual recognition, is the core technology for achieving automatic charging; the device body 110 of the mobile charging device integrates advanced charging equipment 1102 and an intelligent control system 1101, which can improve charging efficiency and stability.
