The terminology used in the specification herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure.

[0023] In various embodiments, for the purpose of description but not limitation of the present disclosure, the term "connected" used in the patent application specification and claims of the present disclosure is not limited to physical or mechanical connection, but can include electrical connection, whether direct or indirect. "Up", "down", "below", "left", "right", and the like are only used to represent relative positional relationships, which change accordingly when the absolute position of the described object changes.

[0024] Figure 1 is a structural schematic diagram of the battery replacement device. As shown in Figure 1 , the battery replacement device includes a telescopic arm 20, a lifting and taking seat 30, a grabbing piece 40, and a snow clearing mechanism. The telescopic arm 20 can be connected to other components, for example, a rack that can move the telescopic arm 20 in the horizontal direction and the vertical direction, the telescopic arm 20 can be extended or shortened to move the lifting and taking seat 30 at the end along the horizontal direction.

[0025] The lifting and taking seat 30 is used to move the battery pack 10 above the battery pack 10. Specifically, the lifting and taking seat 30 is connected to the grabbing piece 40 through the connecting rope 41, and the grabbing piece 40 can be lifted and moved in the vertical direction under the traction of the connecting rope 41. The grabbing piece 40 is used to dock the battery pack 10, and the battery pack 10 is moved by the lifting and taking seat 30. In order to facilitate the adjustment of the position of the grabbing piece 40, in the present embodiment, the lifting and taking seat 30 is movably connected to the telescopic arm 20 along the telescopic direction of the telescopic arm 20 through a guide rail and sliding block mechanism, which is used to fine adjust the position between the grabbing seat and the battery pack 10.

[0026] Figure 2 is a three-dimensional structural schematic diagram of the snow clearing mechanism. As shown in Figure 2As shown, the snow cleaning mechanism is connected to the grabbing member 40. The snow cleaning mechanism can clean the snow, dust, debris and the like on the top of the battery pack 10 before the grabbing member 40 docks with the battery pack 10, thereby improving the reliability of the grabbing member 40 docking with the battery pack 10 and automatically cleaning the battery pack 10.

[0027] Specifically, the snow cleaning mechanism of the battery pack 10 includes a connecting assembly and a cleaning assembly. The connecting assembly is used to connect the grabbing member 40 and the cleaning assembly, and adjust the position of the cleaning assembly so as to clean the top of the battery pack 10.

[0028] Figure 3 is a side view of the snow cleaning mechanism. As shown in Figure 2 and 3 As shown, the connecting assembly includes a connecting arm 51 and a telescopic rod 50. The connecting arm 51 is used to connect the cleaning assembly, and the telescopic rod 50 is used to swing the connecting arm 51 to adjust the position of the cleaning assembly relative to the battery pack 10.

[0029] Specifically, one end of the connecting arm 51 is rotatably connected to the grabbing member 40 of the battery swapping device, and the other end is connected to the cleaning assembly. In order to improve the swing range of the free end of the connecting arm 51 (the end connected to the cleaning assembly) and the posture of the cleaning assembly docking with the battery pack 10, in this embodiment, the middle part of the connecting arm 51 is bent downward to form a bent part, and generally forms a "C" shape. The telescopic rod 50 can be a pneumatic or hydraulic telescopic rod 50. One end is rotatably connected to the bent part of the connecting arm 51, and the other end is rotatably connected to the grabbing member 40. During operation, the connecting arm 51 is driven to swing through the telescopic action of the telescopic rod 50. In order to improve the connection strength of the cleaning assembly, in this embodiment, the connecting arm 51 and the telescopic rod 50 are a pair. One connecting arm 51 and one telescopic rod 50 are arranged on both sides of the grabbing member 40 in the telescopic direction. The two telescopic rods 50 synchronously drive the connecting arm 51 to swing synchronously. Those skilled in the art understand that the number of telescopic rods 50 can also be one. The telescopic rod 50 synchronously connects two connecting arms 51 to drive a pair of connecting arms 51 to swing synchronously.

[0030] Figure 4 is a structural schematic view of the cleaning assembly. As shown in Figure 4 The cleaning assembly includes a snow sweeping motor 61 and a roller 60. The roller 60 is rotatably connected to the other end of the connecting arm 51. The snow sweeping motor 61 is connected to the roller 60 and is used to drive the roller 60 to rotate.

[0031] The roller 60 includes a roller shaft 601 and a brush 602. The roller shaft 601 is rotatably connected to the connecting arm 51. One end of the brush 602 is connected to the roller shaft 601, and the other end extends in the radial direction. The roller 60 includes a plurality of rows of the brush 602.

[0032] In order to drive the roller 60 to rotate, in the embodiment, the cleaning assembly further comprises a transmission wheel 63 connected to the roller 60 and a transmission belt 62 connected to the snow sweeping motor 61 and the transmission wheel 63. The cleaning assembly further comprises a synchronous shaft 611 connected to the snow sweeping motor 61, rotatably connected to the connecting arm 51 at both ends, and connected to the roller 60 at both ends through the transmission belt 62 and the transmission wheel 63. In this way, the snow sweeping motor 61 drives the roller shaft 601 of the roller 60 to rotate through the synchronous shaft 611, the transmission belt 62 and the transmission wheel 63, and the rolling brush 602 is swung to rotate to beat the top of the battery pack 10, thereby cleaning the top of the battery pack 10.

[0033] In operation, after the telescopic arm 20 moves the grabbing piece 40 to a position close to the battery pack 10, the snow sweeping motor 61 is started, the telescopic rod 50 drives the connecting arm 51 to swing downward, and the roller 60 is moved to the top of the battery pack 10. Then, the lifting piece moves along the telescopic direction of the telescopic arm 20, and the roller 60 is moved by the grabbing piece 40. In the moving process, the roller 60 rotates to beat the top of the battery pack 10, thereby cleaning the snow and other sundries on the top of the battery pack 10. After the cleaning is completed, the telescopic rod 50 is reset, the connecting arm 51 swings upward, and the roller 60 is separated from the battery pack 10; the lifting seat 30 is reset, and the subsequent battery replacement operation is continued.

[0034] The snow cleaning mechanism of the battery pack 10 and the telescopic rod 50 driving the connecting arm 51 to swing to move the roller 60 to the upper part of the battery pack 10 in the above-described battery replacement equipment can drive the roller 60 to rotate to clean the snow on the top of the battery pack 10 by the snow sweeping motor 61. After the cleaning is completed, the telescopic rod 50 swings through the connecting arm 51, so that the roller 60 can be separated from the battery pack 10, and the battery replacement operation is not affected.
