Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted charging and battery swapping technology, specifically to a vehicle-mounted mobile charging and battery swapping system. Background Technology

[0002] With the increasing popularity of new energy vehicles, the construction of charging infrastructure has become crucial. Traditional fixed charging piles suffer from problems such as inflexible layout, long construction period, and high cost, making it difficult to meet the rapidly growing charging demand. The charging difficulty is even more prominent in remote areas, temporary activity venues, and during peak charging demand periods. Vehicle-mounted mobile charging and swapping equipment can provide a flexible, efficient, safe, and universal charging and swapping solution.

[0003] As disclosed in CN112477684B, a vehicle-mounted mobile telescopic track-type charging and swapping device relates to the field of new energy technology, including a chassis, a trolley mechanism, and a battery swapping mechanism. A battery pack base is mounted on the chassis, and a track extending along the length of the chassis is also mounted on the chassis. The trolley mechanism includes a trolley body and a traveling device. The trolley body is movably mounted on the track, and the traveling device is connected to the trolley mechanism, driving the trolley mechanism to move along the track. The battery swapping mechanism is mounted on the trolley mechanism and includes a telescopic device that extends perpendicular to the track and a lifting device mounted on the telescopic device, with a gripper connected to the lifting device. This invention solves the problems of large footprint, required infrastructure, and high cost associated with fixed charging stations. Furthermore, the battery swapping device of this application can be moved to a unified site for centralized management, solving the problems of scattered charging pile distribution and inconvenient maintenance.

[0004] As disclosed in CN214775475U, a vehicle-mounted mobile folding arm charging and swapping device includes an electric vehicle head, a chassis, and a battery swapping mechanism. The chassis is connected to the electric vehicle head; a battery pack base is mounted on the chassis. The battery swapping mechanism includes a folding arm robotic arm and a gripper. The folding arm robotic arm includes a basic arm rotatable around its axis and a foldable arm foldably connected to the basic arm. The basic arm is connected to the chassis, and the gripper is connected to the foldable arm. The vehicle-mounted mobile folding arm charging and swapping device provided in this application mounts the conventionally used battery pack base on the chassis, solving the problems of large footprint, infrastructure requirements, and high costs associated with fixed charging stations, and improving battery swapping efficiency. The charging and swapping device of this application can be moved to a unified site for centralized management, solving the problems of scattered charging pile distribution and inconvenient maintenance.

[0005] However, existing vehicle-mounted mobile charging and battery swapping systems still have the following shortcomings:

[0006] 1. Existing vehicle-mounted mobile charging and swapping systems mostly rely on wheels to directly contact the ground during the charging and swapping process. This results in a limited contact area with the ground, low friction, and affects stability during the charging and swapping process.

[0007] 2. Existing vehicle-mounted mobile charging and swapping systems are inconvenient for adjusting the angle of the battery during swapping, and the stability of the battery during lifting and lowering is poor;

[0008] 3. Existing vehicle-mounted mobile charging and swapping systems have poor versatility because different vehicle models have different battery capacities and sizes, making it inconvenient to adjust the swapping equipment according to the size of the battery.

[0009] Therefore, we propose a vehicle-mounted mobile charging and battery swapping system to address the problems mentioned above. Summary of the Invention

[0010] The purpose of this invention is to provide a vehicle-mounted mobile charging and swapping system to solve the problems mentioned in the background art, where the charging and swapping process is mostly carried out by placing the device directly on the ground via wheels. This results in a limited contact area with the ground, low friction, and affects stability during the charging and swapping process. It is also inconvenient to adjust the angle of the battery during swapping, and the battery's stability during lifting and lowering is poor. Furthermore, since different vehicle models have different battery capacities and sizes, it is inconvenient to adjust the swapping device accordingly based on the battery size, resulting in poor versatility.

[0011] To achieve the above objectives, the present invention provides the following technical solution: a vehicle-mounted mobile charging and swapping system, comprising an AGV trolley and a battery carrier;

[0012] Also includes:

[0013] The AGV is equipped with stabilizing components on both the left and right sides. The stabilizing components include a support plate that flips on the side of the AGV, an anti-slip pad at the lower end of the support plate, a connecting rod fixedly connected to the upper end of the support plate, and a drive component on the AGV.

[0014] The outer side of the battery carrier plate is provided with an auxiliary support side plate that can be telescopically moved and adjusted at equal angles. The auxiliary support side plate is connected to the battery carrier plate through a connecting assembly nested below.

[0017] Preferably, the AGV trolley has fixed plates fixedly connected to both the front and rear sides of its upper end, and a hydraulic cylinder is installed in the middle of the upper end of the AGV trolley. The output end of the hydraulic cylinder is fixedly connected to a drive plate, and the front and rear sides of the lower end of the drive plate are fixedly connected to vertical rods for limiting the position.

[0018] The drive board has balls rolled at equal angles at its upper end, and a speed-reducing stepper motor is installed in the middle of the drive board. The output end of the speed-reducing stepper motor is connected to a support plate fixed at the lower end of the battery carrier board.

[0019] Preferably, the vertical rod and the fixed plate form an up-and-down sliding structure.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figures 1-12 The present invention provides the following technical solution:

[0045] To address the problems existing in the prior art, the present invention provides a vehicle-mounted mobile charging and swapping system, comprising an AGV trolley 1 and a battery carrier plate 15. Stabilizing components are provided on both the left and right sides of the AGV trolley 1. An auxiliary support side plate 18 capable of telescopic movement and adjustment is provided at equal angles on the outer side of the battery carrier plate 15. The auxiliary support side plate 18 is connected to the battery carrier plate 15 through a connecting component nested below. The connecting component includes a fixed cylinder 20 fixed at the lower end of the battery carrier plate 15 and a movable column 21 inserted into the middle of the fixed cylinder 20. An industrial camera 19 is installed on the outer side of the auxiliary support side plate 18, and the auxiliary support side plate 18 is fixed above the far end of the movable column 21.

[0046] like Figure 1 As shown, the AGV trolley 1 has a charging module on its front side, which integrates a charging control unit and a charging interface. The charging control unit can intelligently adjust parameters such as charging voltage and current based on information from the battery management system of the vehicle being charged, enabling switching between various charging modes such as constant current charging and constant voltage charging. The charging module can charge the vehicle. When a battery swap is needed, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, firstly, based on the vehicle signal and the size of the battery pack, the position of the auxiliary support side plate 18 is adjusted through the setting of the connecting components. Pulling the fixing ring 27 causes the auxiliary rod 24 to slide in the connecting column 23. The auxiliary rod 24 is connected to the positioning plate 26. The auxiliary rod 24 causes the positioning plate 26 to slide between the connecting column 23. The positioning plate 26 compresses the spring 25, causing the spring 25 to undergo elastic deformation. The positioning plate 26 disengages from the protrusion 22, thereby releasing the limit between the fixing cylinder 20 and the movable column 21. Then, by pulling the movable column 21, the movable column 21 slides between the fixed cylinder 20 and the fixed cylinder 20. The movable column 21 drives... The connecting column 23 moves inside the fixed cylinder 20, and the movable column 21 moves and adjusts the position of the auxiliary support side plate 18 to adjust the distance between the auxiliary support side plate 18 and the battery carrier plate 15 so that the distance between the two opposing auxiliary support side plates 18 is close to the length and width of the battery pack. After the adjustment is completed, the fixing ring 27 is released directly. At this time, the spring 25 returns to its elastic deformation, which causes the auxiliary rod 24 to push the positioning plate 26 to engage with the corresponding protrusion 22, thereby facilitating the limiting of the connection column 23 and the fixed cylinder 20, and fixing the movable column 21 and the auxiliary support side plate 18.

[0047] Then, the AGV trolley 1 is started by the controller, moving it to a position below the battery pack. The industrial camera 19, electrically connected to the built-in vision processing unit, captures images of the battery pack. The camera analyzes the images and adjusts the position of the battery swapping equipment accordingly based on the battery pack's location. Simultaneously, the deceleration stepper motor 13 drives the support plate 14 to slowly rotate the battery carrier plate 15, adjusting the positions of the battery carrier plate 15 and the auxiliary support side plate 18 to align with the battery pack. The ball bearings 17 engage in the annular groove 16 and roll within it, improving stability during rotation. After positioning, as shown... Figure 1 , Figure 4 and Figure 5 As shown, stabilizing components are installed on both the left and right sides of the AGV trolley 1. The stabilizing components include a support plate 5 that flips on the side of the AGV trolley 1, an anti-slip pad 6 located at the lower end of the support plate 5, a connecting rod 7 fixedly connected to the upper end of the support plate 5, and a drive component installed on the AGV trolley 1. The drive component consists of an electric telescopic rod 2 installed on the left and right sides of the upper end of the AGV trolley 1, a movable block 3 fixed to the output end of the electric telescopic rod 2, a limiting rail 4 located at the lower end of the movable block 3, and a movable sleeve 8 hinged to the outside of the movable block 3. The electric telescopic rod 2 is started by the controller, and the electric telescopic rod 2 pushes the movable block 3 to slide between the limiting rail 4, thereby driving the movable block 3 to rotate between the movable sleeve 8. The movable sleeve 8 drives the outer surface of the connecting rod 7 to slide, thereby driving the support plate 5 to flip on both sides of the AGV trolley 1. The lower end of the support plate 5, together with the anti-slip pad 6, is placed on the ground, which can support the equipment, increase the contact area and friction between the equipment and the ground, and improve the stability during the battery swapping process.

[0048] Then, the hydraulic cylinder 10 is activated by the controller. The hydraulic cylinder 10 drives the drive plate 11 to move slowly upward. The drive plate 11 drives the vertical rod 12 to slide up and down with the fixed plate 9, thereby improving the stability of the battery carrier plate 15 during the lifting process. The battery carrier plate 15, together with the auxiliary support side plate 18, moves upward to support the battery pack. Then, the staff can manually or through an external robotic arm device remove the battery pack. The battery pack can be supported by the battery carrier plate 15 and the auxiliary support side plate 18. The hydraulic cylinder 10 retracts downward, causing the battery pack to move downward and detach from the vehicle body. The stabilizing component is retracted, and then the AGV trolley 1 moves the battery pack out. After removal and unloading, the fully charged battery pack is placed on the upper end of the battery carrier plate 15 and the auxiliary support side plate 18. The above operation is repeated to position and install the fully charged battery pack to complete the battery swap.
