[0043] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0044] This application provides a mobile charging device. Figure 1 is a side view of the mobile charging device provided in this application, Figure 2 is a side view of the mobile charging device providing charging for a vehicle provided in this application, and Figure 3 is a top view of the mobile charging device providing charging for a vehicle provided in this application. As shown in Figures 1-3, the mobile charging device includes a device body 110, a suspension system 120, and a moving system 130.

[0045] One end of the suspension system 120 is fixedly connected to the bottom of the device body 110, and the other end of the suspension system 120 is connected to the moving system 130. The width d1 of the device body 110 is greater than the width d2 of the vehicle to be charged.

[0046] The main body 110 of the device includes a charging device 1101 and a control system 1102. The mobile system 130 is communicatively connected to the control system 1102. The mobile system 130 is used to move the mobile charging device. When the control system 1102 receives a charging demand signal from a vehicle to be charged, it obtains the location of the vehicle to be charged and controls the mobile charging device to move to the location of the vehicle to be charged through the mobile system 130 and straddle the vehicle to be charged. The control system 1102 is also used to control the connection between the charging device 1101 and the charging interface of the vehicle to be charged.

[0047] As shown in Figures 2 and 3, the black dashed line in Figure 3 represents the outline of the mobile charging device, and it also shows the vehicle to be charged, the suspension system 120, and the moving system 130 through the device body 110, illustrating the positional relationship between the mobile charging device and the vehicle to be charged. The width d1 of the device body 110 is set greater than the width d2 of the vehicle to be charged, allowing the mobile charging device to straddle the vehicle. This eliminates the limitations of parking space spacing, avoids occupying additional parking area, and does not hinder the normal exit of the vehicle to be charged or surrounding vehicles, greatly improving charging convenience. The moving system 130 can be a wheel structure, a tracked structure, or other types of mobile devices. The type of mobile charging device can be a mobile charging vehicle. The device body 110 can be the vehicle's body, the suspension system 120 can be the vehicle's suspension, and the moving system 130 can be the vehicle's wheels. The design and manufacture of the device body 110, suspension system 120, and moving system 130 meet vehicle manufacturing requirements, ensuring their strength and stability can support the entire vehicle, enabling the vehicle to charge while moving.

[0048] For example, referring to Figure 1, the main body 110 of the device includes a charging device 1101 and a control system 1102. The charging device 1101 can be a battery device capable of charging the vehicle to be charged. The control system 1102 can control the movement of the mobile charging device and control the charging device 1101 to connect to the vehicle to be charged, thereby realizing automatic charging of the vehicle to be charged. During use, the vehicle to be charged can send a charging demand signal to the control system 1102. The charging demand signal can be sent through the vehicle's infotainment system or through the user's mobile phone. When the control system 1102 receives the charging demand signal from the vehicle to be charged, it can obtain the location of the vehicle to be charged and control the mobile charging device to move to the location of the vehicle to be charged through the mobile system 130, and place it over the vehicle to be charged. This ensures that the mobile charging device does not occupy parking spaces around the vehicle to be charged and does not affect the normal entry and exit of the vehicle to be charged and surrounding vehicles, thereby greatly improving the convenience of charging. The control system 1102 is also used to control the connection between the charging device 1101 and the charging interface of the vehicle to be charged, so that users can enjoy automatic charging service without manually connecting the charging cable, simply by sending a charging demand signal. During the charging process using this mobile charging device, users do not need to find fixed charging stations; the mobile charging device can autonomously move to the vehicle's location to charge, greatly improving the user experience. Furthermore, there is no need to queue for charging stations, improving vehicle charging efficiency and convenience, significantly enhancing the user's charging experience. In addition, using the mobile charging device of this application eliminates the need to install fixed charging stations for each parking space, saving on parking lot construction and maintenance costs.

[0049] The length of the main body 110 can be greater than the length of the vehicle to be charged, to increase the energy storage capacity of the charging device 1101 within the main body 110, or it can be less than the length of the vehicle to reduce the overall size of the mobile charging device, thus adapting to more application scenarios; no limitation is imposed here. The height of the main body 110 can be greater than the maximum height of the vehicle to be charged, ensuring that the mobile charging device can straddle the vehicle to charge it without occupying additional parking space or affecting the normal exit of the vehicle to be charged and surrounding vehicles. The height of the main 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, allowing the mobile charging device to straddle the front or rear of the vehicle to charge it, again without occupying additional parking space. The width d1 of the main body 110 is greater than the width d2 of the vehicle to be charged, but the width d1 of the main body 110 should not exceed the maximum width of the parking space in the parking lot where the vehicle to be charged is located, to avoid occupying additional parking spaces and to ensure that the normal exit of the vehicle to be charged and surrounding vehicles is not affected, thus greatly improving the convenience of charging.

[0050] This application provides a mobile charging device, which includes a main body, a suspension system, and a moving system. One end of the suspension system is fixedly connected to the bottom of the main body, and the other end is connected to the moving system. The width of the main body is greater than the width of the vehicle to be charged, allowing the mobile charging device to straddle the vehicle. The main body contains a charging device and a control system, and the moving system is communicatively connected to the control system. The moving system is used to move the mobile charging device. When the control system receives a charging request signal from the vehicle to be charged, it obtains the location of the vehicle and controls the mobile charging device to move to the location of the vehicle and straddle it. This allows the mobile charging device to be unrestricted by parking space spacing, without occupying additional parking area, and without affecting the normal exit of the vehicle and surrounding vehicles. The control system can also control the connection between the charging device and the charging interface of the vehicle. During the charging process, users do not need to find a fixed charging station; the mobile charging device can autonomously move to the vehicle's location to charge, greatly improving the user experience. Furthermore, it eliminates the need to queue for charging stations, improving charging efficiency and convenience, and significantly enhancing the user's charging experience. Furthermore, using the mobile charging device of this application embodiment eliminates the need to install fixed charging piles for each parking space, saving on parking lot construction and maintenance costs.

[0051] To further improve the convenience of vehicle charging, this application provides another mobile charging device. Figure 4 is a schematic diagram of the structure of another mobile charging device provided in this application. As shown in Figure 4, the charging device 1102 includes a battery 1102a and a charging gun 1102b.

[0052] The storage battery 1102a is electrically connected to the charging gun 1102b, the mobile system 130 and the control system 1101 respectively. The storage battery 1102a is installed inside the equipment body 110, and the charging gun 1102b is installed outside the equipment body 110.

[0053] Battery 1102a is used to power charging gun 1102b, mobile system 130 and control system 1101, and charging gun 1102b is used to connect to the charging interface of the vehicle to be charged.

[0054] For example, the battery 1102a stores electrical energy, which can power the charging gun 1102b, the mobile system 130, and the control system 1101. In addition, other electrical devices in the mobile charging equipment 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, it can charge the vehicle.

[0055] Optionally, as shown in Figure 4, the mobile charging device also includes a robotic arm 140 and a visual recognition device 150; the visual recognition device 150 is mounted on the robotic arm 140, and the robotic arm 140 is mounted on the main body 110 of the device; the robotic arm 140 is used to grasp the charging gun 1102b.

[0056] The visual recognition device 150 is communicatively connected to the control system 1101. The visual recognition device 150 is used to collect image information of the area surrounding the robotic arm 140 and send it to the control system 1101. The image information of the area surrounding 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. The control system 1101 is also used to control the robotic arm 140 to grasp the charging gun 1102b and connect it to the charging interface of the vehicle to be charged when the mobile charging device moves to the location of the vehicle to be charged, based on the image information of the area surrounding the robotic arm 140.

[0057] The control system 1102 is also used to monitor the charging status of the vehicle to be charged. After the vehicle to be charged is fully charged, the control system 1102 controls the robotic arm 140 to grab the charging gun 1102b based on the image information of the area surrounding the robotic arm 140, so that the charging gun 1102b is disconnected from the charging interface of the vehicle to be charged.

[0058] The visual recognition device 150 can be a camera. The visual recognition device 150 can collect image information of the area surrounding the robotic arm 140. The control system 1102 can extract the image information of the charging interface of the vehicle to be charged from the image information of the area surrounding the robotic arm 140, and determine the position of the charging interface based on 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 to it.

[0059] For example, the control system 1101 is communicatively connected to the robotic arm 140. When the mobile charging device moves to the location of the vehicle to be charged, the control system 1101 controls the robotic arm 140 to grab the charging gun 1102b and connect it to the charging interface of the vehicle to be charged based on the image information of the area surrounding the robotic arm 140. This allows the user to enjoy automatic charging service without having to manually connect the charging cable, simply by sending a charging demand signal.

[0060] Optionally, the robotic arm 140 and the charging gun 1102b can be integrated into one unit.

[0061] For example, the charging gun 1102b is disposed at the end of the robotic arm 140, thereby allowing the robotic arm 140 to directly control the position of the charging gun 1102b. The robotic arm 140 can directly connect to and control the connection and disconnection of the charging gun 1102b. Currently, in the above embodiment, the robotic arm 140 and the charging gun 1102b can be separately disposed, thereby facilitating manual disconnection of the charging gun 1102b by the user.

[0062] In this embodiment, the mobile charging device moves automatically within the site via a control system 1101, proceeding to the corresponding location based on the charging demand signal of the vehicle to be charged. Upon arrival, the mobile charging device stably straddles the vehicle. Then, a robotic arm 140 descends from the main body 110 of the mobile charging device. The robotic arm 140 accurately locates and connects to the charging port of the vehicle using the visual recognition function of the visual recognition device 150, initiating automatic charging. During the charging process, the control system 1101 monitors the charging status of the vehicle in real time to ensure safety and stability. After charging is complete, the robotic arm 140 automatically retracts, and the mobile charging device moves to the next charging demand location or a waiting area. This embodiment of the mobile charging device can autonomously move to the vehicle's location for charging, without being limited by parking space spacing, greatly improving user experience, charging efficiency, and convenience.

[0063] 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 moving next to the vehicle to be charged, so that the chassis height of the main body of the equipment 110 is higher than the height of the vehicle to be charged.

[0064] For example, the height of the suspension system 120 is adjustable, thus accommodating vehicles of different heights for charging. This allows the mobile charging device to be used with different vehicle models, such as sedans, SUVs, and trucks, improving its versatility. Furthermore, by lowering the height of the suspension system 120, the overall height of the mobile charging device is reduced, facilitating its placement and transportation and saving space. When the control system 1101 moves to the side of the vehicle to be charged, it simultaneously acquires the vehicle's height information and controls the suspension system 120 to rise, ensuring the chassis height of the device body 110 is higher than the height of the vehicle. This allows the mobile charging device to straddle the vehicle and charge it.

[0065] Optionally, the height of the suspension system 120 is fixed, and the chassis height of the main body of the equipment 110 is higher than the height of the vehicle to be charged.

[0066] For example, the height of the suspension system 120 is fixed, which can improve the overall structural strength of the mobile charging device. The height of the suspension system 120 can make 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 vehicle to be charged and charge the vehicle.

[0067] Optionally, the mobile system 120 includes two tracks, which are connected to both sides of the equipment body 110 via the suspension system 120.

[0068] For example, the mobile charging device moves via two tracks, giving it a certain degree of off-road capability and high stability for use in challenging terrains. The distance between the two tracks should be greater than the width of the vehicle being charged, allowing the mobile charging device to straddle the vehicle and charge it.

[0069] Optionally, the mobility system 120 includes at least four wheels, and the suspension system 120 includes at least four suspension arms, with each wheel mounted to one end of a suspension arm and the other end of the suspension arm mounted to the equipment body 110.

[0070] For example, the mobile system 120 includes at least four suspension arms, with each wheel mounted to one end of a suspension arm and the other end of the suspension arm mounted to the device body 110. The mobile charging device moves via these at least four wheels. For example, referring to FIG3, when the mobile system 120 has four suspension arms and includes four wheels, the four wheels are respectively mounted to one end of each suspension arm, and the four wheels are respectively connected to both sides of the device body 110 via the four suspension arms. The distance between two opposite wheels should be less than the width of the vehicle to be charged, so that the mobile charging device can straddle the vehicle to be charged and charge it. This allows the mobile charging device to be unrestricted by parking space spacing, not occupy additional parking area, and not affect the normal exit of the vehicle to be charged and surrounding vehicles from the parking space.

[0071] Optionally, the wheel track between the two opposing wheels is adjustable, and the control system is also used to ensure that the wheel track is greater than the width of the vehicle to be charged when moving next to it.

[0072] For example, the wheelbase of the two opposing wheels is adjustable. By controlling the wheelbase through a control system, the mobile charging device can be positioned over vehicles of different widths, eliminating parking space limitations. Furthermore, the adjustable wheelbase allows the mobile charging device to be used with various vehicle models, such as sedans, SUVs, and trucks, improving its versatility. Additionally, by making the wheelbase adjustable, the overall width of the mobile charging device is reduced when the wheelbase is decreased, facilitating placement and transportation and saving space.

[0073] Optionally, the wheel track between the two opposite wheels is fixed and is greater than the width of the vehicle to be charged.

[0074] For example, a fixed wheelbase between two opposing wheels can improve the overall structural strength of the mobile charging device, and the wheelbase is greater than the width of the vehicle to be charged, so that the mobile charging device can straddle the vehicle to be charged and charge the vehicle, making the mobile charging device not limited by the distance between parking spaces.

[0075] In this embodiment, the suspension system 120 and the main body 110 of the mobile charging device are designed and manufactured to meet requirements, ensuring their strength and stability can support the entire mobile charging device and meet the height requirements of crossing vehicles. An advanced charging device 1102 and an intelligent control system 1101 are integrated within the main body 110. The charging device 1102 has efficient charging capabilities and safety protection functions, while the control system 1101 can achieve automatic navigation, positioning, and charging control. An automatic charging robotic arm 140 is designed and manufactured. The robotic arm 140 should have high-precision visual recognition and positioning capabilities and a reliable connection mechanism, enabling it to quickly and accurately dock with charging interfaces of different electric vehicles. Additionally, a charging demand signal receiving device can be installed at the location of the mobile charging device. When a vehicle needs charging, the signal is received by the charging demand signal receiving device and transmitted to the control system 1101 of the mobile charging device, allowing the mobile charging device to autonomously move to the location of the vehicle. During field testing, 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, each part is optimized and improved to ensure that the vehicles to be charged can operate reliably in various real-world scenarios.

[0076] Furthermore, the mobile charging device in this embodiment combines a high chassis design with an ultra-high suspension, enabling it to stably straddle the vehicle to be charged and achieve automatic charging, which is key to solving the problem of charging convenience. The design of the automatic charging robotic arm 140, and the positioning of the charging port of the vehicle to be charged by the vision recognition device 150 with high-precision vision recognition, are the core technologies for achieving automatic charging. The main body 110 of the mobile charging device integrates an advanced charging device 1102 and an intelligent control system 1101, which can improve charging efficiency and stability.

[0077] The mobile charging device of this application embodiment has the following advantages: 1. Improved charging convenience: Users do not need to find fixed charging piles; the mobile charging device can autonomously move to the location of the vehicle to be charged, greatly improving the user experience; 2. Improved charging efficiency: The automatic charging process requires no manual intervention, saving time and improving charging efficiency; 3. Reduced costs: There is no need to install fixed charging piles for each parking space, saving parking lot construction and maintenance costs; 4. Simple operation: Users do not need to manually connect the charging cable; they only need to send a charging demand signal to enjoy automatic charging service. Furthermore, mobile charging devices in related technologies are bulky, and if the parking space spacing is small, they cannot charge cars. The mobile charging device of this application embodiment does not occupy additional parking space, solving the problem in related technologies where electric vehicle charging piles can only charge electric vehicles parked in pre-set locations, and where gasoline and electric vehicles cannot be parked together. It allows electric and gasoline vehicles to share the same parking space.

[0078] This application provides a mobile charging device. During the charging process, the mobile charging device eliminates the need for users to find fixed charging stations; it can autonomously move to the vehicle's location to charge, significantly improving the user experience. Furthermore, it eliminates the need to queue for charging stations, increasing charging efficiency and convenience, thus greatly enhancing the user's charging experience. In addition, using the mobile charging device of this application eliminates the need to install fixed charging stations for each parking space, saving on parking lot construction and maintenance costs.

[0079] This application also provides a control method for a mobile charging device. The control method is applied to the mobile charging device in any embodiment of this application. Figure 5 is a flowchart of a control method for a mobile charging device provided in an embodiment of this application. As shown in Figure 5, the control method includes:

[0080] S110. Upon receiving a charging request signal from a vehicle to be charged, obtain the location of the vehicle to be charged.
