[0063] The utility model will be described below with a preferred embodiment, and in conjunction with the drawings more clearly and completely.

[0064] The embodiment provides a battery swap station, which is used for replacing the battery of an electric vehicle, and the battery swap station comprises a battery swap device, and the battery swap device is used for transporting and disassembling a battery pack.

[0065] As Figures 1 to 3As shown, the embodiment provides a battery replacement device for carrying and replacing the battery pack of an electric vehicle, which comprises a base plate 110, a vehicle connecting plate 120 and a sliding support 150. The base plate 110 is located on the upward side of the battery replacement device. The vehicle connecting plate 120 is used to connect the electric vehicle, and can move in the vertical direction of the moving direction of the battery replacement device to adapt to the position of the electric vehicle. The sliding support 150 is arranged on the base plate 110 close to the side of the vehicle connecting plate 120 away from the center of the battery replacement device, and the sliding support 150 and the vehicle connecting plate 120 are slidingly supported.

[0066] The vehicle connecting plate 120 is arranged on the base plate 110 and can move in the vertical direction of the moving direction of the battery replacement device. In this way, the adjustment in multiple directions can be realized by cooperating with the movement of the battery replacement device itself, so as to better align with the electric vehicle. The vehicle connecting plate 120 is driven by two first driving motors 122 arranged on the base plate 110 of the battery replacement device.

[0067] As shown in Figure 2 , Figure 3 , the vehicle connecting plate 120 is provided with a positioning column 121 for cooperating with the vehicle, and the sliding support 150 is arranged close to the positioning column 121. The positioning column 121 is the main force bearing structure, and arranging the sliding support 150 near the positioning column 121 can better realize its supporting effect and prevent deformation.

[0068] When replacing the battery, the battery replacement device can realize the adjustment in four directions of front, back, left and right by the movement of itself and the movement of the vehicle connecting plate 120 to align with the electric vehicle. The vehicle connecting plate 120 needs to be connected with the vehicle, and the end thereof is easy to be bent under stress during the connection. By arranging the sliding support 150 to support between the base plate 110 and the vehicle connecting plate 120, effective support can be provided to prevent the deformation of the vehicle connecting plate 120. At the same time, the sliding support 150 and the vehicle connecting plate 120 are slidingly connected, which supports while not affecting the movement of the vehicle connecting plate 120.

[0069] The battery replacement device comprises a plurality of sliding supports 150. As shown in Figure 4 , two sliding supports 150 are arranged on the base plate 110 in the embodiment, and the two sliding supports 150 are arranged at the left and right ends of the vehicle connecting plate 120 respectively, which can improve the supporting effect.

[0070] As shown in Figure 4 , Figure 5As shown, the sliding support 150 includes a support part 151 and a sliding part 152, the support part 151 is fixed with the base plate 110, and the sliding part 152 is detachably arranged above the support part 151, and the support part 151 is fixed with the vehicle connecting plate 120 through the sliding part 152. The strength of the support part 151 is greater than that of the sliding part 152, and the surface smoothness of the sliding part 152 is greater than that of the support part 151.

[0071] The sliding support 150 is arranged in two parts, so that the two parts only need to select the required materials according to their functions, and the support part 151 itself only plays a supporting role, so it only needs to select a material with high strength, without considering the surface smoothness and wear resistance. The sliding part 152 only plays the role of a sliding base, and only needs to ensure smoothness and wear resistance, without considering strength. This can reduce the requirements for the physical properties of the material of the sliding support 150, thereby reducing costs. In addition, the sliding part 152 is a consumable part, and the detachable connection facilitates maintenance and replacement.

[0072] As shown in Figure 5 , the edges of the support part 151 extend upwards and around the vehicle connecting plate 120 to form a receiving groove 154, and the vehicle connecting plate 120 passes through the receiving groove 154. By arranging the receiving groove 154, the connecting plate can be guided and limited to a certain extent to prevent it from shaking and moving in directions other than its movement direction, thereby improving stability. The receiving grooves 154 on both sides of the vehicle connecting plate 120 are arranged towards each other, and the vehicle connecting plate 120 is limited therein. Further improve the limiting effect.

[0073] As shown in Figure 5 , in this embodiment, one side of the support part 151 extends outward to form an extension part 153, and the sliding part 152 is arranged on the extension part 153. In other embodiments, the sliding part 152 can also be arranged at other positions, such as being arranged in the receiving groove 154.

[0074] As shown in Figure 1 , Figure 4 , the battery swap device further includes a battery pack connecting plate, the battery pack connecting plate is used for connecting and carrying the battery pack, and the battery pack connecting plate can move independently along the movement direction of the vehicle connecting plate 120. The battery connecting plate includes an upper layer plate 1301 and a lower layer plate 1302 arranged in two parts but fixed with each other, and the upper layer plate 1301 and the lower layer plate 1302 can also move independently, the lower layer plate 1302 is connected with the second driving motor 131 and can drive the upper layer plate 1301 to move synchronously under the driving of the second driving motor 131. The upper layer plate 1301 is used to carry the battery pack.

[0075] The vehicle connecting plate 120 is disposed between the upper plate 1301 and the lower plate 1302. The sliding support 150 is disposed at the same height as the lower plate 1302, and both are directly disposed on the base plate 110. Therefore, the sliding support 150 is disposed on the battery pack connecting plate, mainly outside the maximum stroke of the lower plate 1302.

[0076] The sliding support 150 is positioned outside the travel range of the battery pack connecting plate, so that the sliding support 150 will not interfere with the movement of the battery pack connecting plate. Therefore, the sliding support 150 and the battery pack connecting plate can be set at the same height without being staggered in height, which can reduce the overall height of the battery swapping equipment.

[0077] like Figure 1 , Figure 6 and Figure 7 As shown, the battery swapping equipment also includes an auxiliary support 140, which is installed on the equipment and supports the battery pack. The auxiliary support 140 is higher than the battery pack connecting plate and can retract to match the height of the connecting plate. The auxiliary support 140 includes a flexible contact end 141, a telescopic column 142, and a buffer 143. The flexible contact end 141 is located at the top of the auxiliary support 140 and can be made of plastic, possessing a certain degree of flexibility to avoid damaging the battery pack. The telescopic column 142 supports the flexible contact end 141 and can extend and retract. The buffer 143 is connected to the telescopic column 142 and can accumulate potential energy when the telescopic column 142 retracts. The buffer 143 can be a spring that retracts to cushion the impact when the battery pack is lowered. The auxiliary support 140 is fixed to the base plate 110 via a base 144.

[0078] When the battery pack is placed, it first contacts the auxiliary support 140, causing the auxiliary support 140 to retract until it rests on the battery pack connecting plate. This process reduces the direct impact force on the battery pack, providing a cushioning effect and preventing damage. Furthermore, the buffer 143 has a certain degree of adaptive extension and retraction. When the battery pack is placed on the battery swapping equipment, multiple auxiliary supports 140 can adaptively adjust according to the battery pack's position, providing leveling and support.

[0079] like Figure 7 As shown, the flexible contact end 141 has a through hole running vertically through it, and the telescopic column 142 has a connecting end 147 and a main body. The connecting end 147 is located at the top of the main body and is used to extend into the through hole for fixation. The connecting end 147 is provided with a threaded hole. After the connecting end 147 extends into the through hole, a screw 145 is used from the top of the flexible contact end 141, passing through the through hole and fixing it to the threaded hole on the connecting end 147.

[0080] Through the structure, the connection strength of the flexible contact end 141 and the telescopic column 142 can be greater, and the defect that all shearing forces are concentrated on the contact surface of the two when they are connected to cause easy bending and fracture can be avoided. The through connection enables the shearing forces to be distributed axially, and the strength is greater.

[0081] As shown in Figure 7 The diameter of the connecting end 147 is smaller than the main body, the connecting position of the connecting end 147 and the main body forms a stepped portion, and the auxiliary support 140 further comprises a gasket 146 arranged on the stepped portion to support the flexible contact end 141 and the telescopic column 142. One end of the buffer 143 abuts against the base plate 110, and the other end abuts against the gasket 146. Through the structure, the radial contact area is further increased by using the stepped portion gasket 146 to share the shearing forces radially.
