DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-12 , the present invention provides the following technical solutions: In order to solve the problems existing in the prior art, the present invention adopts the following technical solutions: a vehicle-mounted mobile charging and swapping system is provided with an AGV trolley 1 and a battery carrier 15, and stabilizing components are provided on the left and right sides of the AGV trolley 1. Auxiliary supporting side panels 18 that can be telescopically adjusted are provided at equal angles on the outer side of the battery carrier 15, and the auxiliary supporting side panels 18 are connected to the battery carrier 15 through mutually nested connecting components below. The connecting components include a fixed cylinder 20 fixed to the lower end of the battery carrier 15 and a movable column 21 inserted in the middle of the fixed cylinder 20. An industrial camera 19 is installed on the outer side of the auxiliary supporting side panel 18, and the auxiliary supporting side panel 18 is fixed above the far end of the movable column 21; like Figure 1 As shown, a charging module is provided on the front side of the AGV trolley 1, and the charging module is integrated with a charging control unit and a charging interface. The charging control unit can intelligently adjust the charging voltage, current and other parameters according to the information fed back by the battery management system of the vehicle to be charged, and realize the switching of various charging modes such as constant current charging and constant voltage charging. The vehicle can be charged through the charging module. When the vehicle needs to be replaced, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, first, according to the vehicle signal and the size of the battery pack, the position of the auxiliary support side plate 18 is adjusted by setting the connecting component, and the fixing ring 27 is pulled to drive the auxiliary rod 24 to slide in the connecting column 23. The auxiliary rod 24 is connected to the positioning plate 26, and the auxiliary rod 24 drives the positioning plate 26 to slide between the connecting column 23. The positioning plate 26 squeezes the spring 25, causing the spring 25 to elastically deform, and the positioning plate 26 is separated from the protrusion 22, thereby releasing the limit between the fixed cylinder 20 and the movable column 21. Then, by pulling the movable column 21, the movable column 21 slides with the fixed cylinder 20, and the movable column 21 drives The connecting column 23 moves inside the fixed cylinder 20, and the movable column 21 drives the auxiliary support side plate 18 to move and adjust the position, thereby adjusting the distance between the auxiliary support side plate 18 and the battery carrier 15 so that the distance between the auxiliary support side plates 18 at the opposite ends is close to the length and width of the battery pack. When the adjustment is completed, the fixing ring 27 is directly loosened. At this time, the spring 25 recovers its elastic deformation, so that the auxiliary rod 24 pushes the positioning plate 26 to engage with the protrusion 22 at the corresponding position, thereby facilitating the limiting of the connection between the fixing cylinder 20 and the fixing of the movable column 21 and the auxiliary support side plate 18. Then the AGV trolley 1 is started by the controller, so that the AGV trolley 1 moves to the bottom of the vehicle battery pack position, and through the setting of the industrial camera 19, the industrial camera 19 is used to capture the image of the battery pack, and the industrial camera 19 is electrically connected to the built-in visual processing unit in the system to process and analyze the image captured by the camera, and can adjust the position of the battery exchange equipment accordingly according to the position of the battery pack. At the same time, according to the position of the battery, the deceleration stepper motor 13 drives the support plate 14 to drive the battery carrier 15 to rotate slowly, and the position of the battery carrier 15 and the auxiliary support side plate 18 is appropriately adjusted to align with the position of the battery pack, and the ball 17 is engaged in the annular groove 16 and rolls in the annular groove 16 at the same time to improve the stability during the rotation process. After the positioning is completed, Figure 1 、 Figure 4 and Figure 5As shown, the left and right sides of the AGV 1 are provided with a stabilizing assembly, which includes a support plate 5 that is flipped on the side of the AGV 1, a non-slip rubber pad 6 provided 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 driving assembly provided on the AGV 1, which is composed of an electric telescopic rod 2 mounted on the left and right sides of the upper end of the AGV 1, a movable block 3 fixed to the output end of the electric telescopic rod 2, a limiting rail 4 provided at the lower end of the movable block 3, and an active sleeve 8 hingedly connected to the outer side 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 movable block 3 and the limiting rail 4, thereby driving the movable block 3 to rotate between the movable block 3 and the active sleeve 8. The active 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 1. The lower end of the support plate 5 together with the non-slip rubber 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 replacement process. Then the hydraulic cylinder 10 is started by the controller, and the hydraulic cylinder 10 drives the driving plate 11 to slowly move upward, and the driving plate 11 drives the vertical rod 12 to slide up and down between the driving plate 11 and 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 manually or through an external mechanical arm device unloads the battery pack. The battery carrier plate 15 and the auxiliary support side plate 18 can support the battery pack. The hydraulic cylinder 10 is retracted downward, so that the battery pack moves downward and is separated from the vehicle body. The stabilizing assembly is retracted, and then the AGV 1 drives the battery pack to move out. After the battery pack is unloaded, 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, thereby completing the battery replacement.
