[0033] The battery replacement cabinet with cleaning function of the battery replacement trolley in the utility model embodiment, when the battery replacement trolley 400 enters and exits the battery access port 110 of the battery replacement cabinet body 100, the blower 220 of the wind knife device 200 starts, and the high-pressure gas sprayed through the wind knife air outlet 231 blows off the impurities such as dust, silt and snow water on the surface of the battery replacement trolley 400, so that the cleaning function of the battery replacement trolley 400 can be realized, and the taking, transporting and grabbing of the battery by the battery replacement trolley 400 in the battery replacement process can be ensured to be carried out smoothly. ​

[0034] In order to adjust the distance between the air outlet 231 of the air knife 230 and the battery swap trolley 400 in the height direction to adapt to battery swap trolleys 400 of different heights, in some embodiments of the utility model, the connecting pipeline 240 can be vertically telescopic, one end of which is fixedly connected with the air outlet of the air blower 220, and the other end is a telescopic end 241 which is fixedly connected with the air inlet 232 of the air knife 230. Correspondingly, the air knife device 200 further comprises a telescopic driving mechanism 250 for driving the connecting pipeline 240 to move up and down to drive the air knife 230 to vertically ascend and descend, thereby adjusting the height of the air knife 230 and further adjusting the distance between the air outlet 231 and the battery swap trolley 400.

[0035] Specifically, the connecting pipeline can be a telescopic corrugated pipe or a multi-layer sleeve structure which is sequentially and movably sleeved, which can not be specifically limited here.

[0036] The telescopic driving mechanism 250 can comprise a telescopic power component 251, a vertical sliding guide assembly 252 and a connecting component 253.

[0037] The telescopic power component 251 provides power for the up-and-down telescoping of the connecting pipeline and is fixedly arranged on the fixed frame 210.

[0038] The connecting component 253 is a movable part which can move up and down, the output end of the telescopic power component 251 is connected with the connecting component 253, and the connecting component 253 is connected with the telescopic end 241 of the connecting pipeline 240. The telescopic power component 251 drives the connecting component 253 to ascend and descend, drives the telescopic end 241 of the connecting pipeline 240 to ascend and descend, drives the connecting pipeline 240 to telescope, and further drives the air knife 230 to vertically ascend and descend, thereby adjusting the height of the air knife 230 and changing the height position of the air outlet 231.

[0039] The vertical sliding guide assembly 252 guides the ascending and descending of the connecting component 253 to make the ascending and descending movement stable and reliable, and further make the ascending and descending movement of the air knife 230 stable and reliable. The vertical sliding guide assembly 252 comprises a fixed part and a sliding part, the fixed part is fixedly arranged on the fixed frame 210, and the sliding part is fixedly arranged on the connecting component 253, and the sliding part and the fixed part are slidingly guided in the vertical direction.

[0040] Specifically, the telescopic power component 251 can be an electric cylinder, an air cylinder, an oil cylinder or a ball screw, and the vertical sliding guide assembly 252 can be a sliding rail and sliding block assembly, which can not be specifically limited here.

[0041] Due to the large length of the air outlet 231 of the air knife 230, the size of the air knife 230 in the length direction of the air outlet 231 is large, in order to further improve the stability and reliability of the lifting movement of the air knife 230, in some embodiments of the utility model, the connecting component 253 is a horizontally extending beam, as shown in Figure 5 and Figure 6 , the extension direction of the connecting component 253 is parallel to the length direction of the air outlet 231 of the air knife 230, and the vertical sliding guide assembly 252 is provided at both ends of the connecting component 253 respectively, and the lifting movement of the connecting component 253 is guided at least at two places, so that the operation is more stable, and shaking or even jamming is avoided, so that the lifting adjustment of the air knife 230 is more stable and reliable.

[0042] In some embodiments of the utility model, as shown in Figure 2 , the air knife device 200 is located at the middle position above the battery access 110, and the length direction of the air outlet 231 of the air knife 230 is parallel to the width direction of the battery access 110, so that the air outlet of the air knife 230 can be concentrated on the battery access 110, and the utilization rate of the air outlet of the air knife 230 and the cleaning effect on the battery access 110 are improved.

[0043] In some embodiments of the utility model, as shown in Figures 1 to 3 , Figure 5 and Figure 6 , the air outlet 231 of the air knife 230 is provided with a brush 233, the brush 233 is located between the battery access 110 and the air outlet 231 of the air knife 230, and the extension direction of the brush 233 is parallel to the length direction of the air outlet 231 of the air knife 230; the height position of the bottom edge of the brush 233 is lower than the height position of the air outlet 231 of the air knife 230, and lower than the upper edge position of the battery access 110. In the process that the high-pressure gas sprayed from the air outlet 231 of the air knife 230 of the air knife device 200 blows off the impurities such as dust, silt and snow water on the surface of the battery swap car 400, the brush 233 can also contact the surface of the battery swap car 400 to assist in sweeping off the impurities on the surface of the battery swap car 400, and the cleaning effect on the battery swap car 400 is further improved.

[0044] In some embodiments of the utility model, as shown in Figures 1 to 4 , the entire air knife device 200 is fixed on the outer side of the battery access 110 of the battery swap cabinet body side plate through the fixing frame 210, and forms an integral structure with the battery swap cabinet body 100. The battery access 110 of the battery swap cabinet body side plate serves as the mounting support component of the air knife device 200, and no additional mounting support component is needed, which is helpful to reduce the space occupation and reduce the cost.

[0045] As shown in Figure 5 and Figure 6As shown, the fixed frame 210 of the air knife device 200 is a rectangular frame structure, including a plurality of horizontal beams and vertical beams connected as a whole, to ensure structural strength on the basis of as light as possible. The air blower 220 is fixedly connected to the plurality of horizontal beams of the fixed frame 210 through a connecting frame 260, and can be reliably connected through multiple screw fastening connections.

[0046] Further, the air outlet 231 of the air knife 230 is inclined outward relative to the battery access port 110 side plate of the battery swap cabinet body, as shown in Figure 3 , that is, the air knife 230 blows air downward (the air outlet direction is shown by arrow II in Figure 3 ), and the downward air blowing is decomposed into horizontal air blowing and vertical downward air blowing. When acting on the surface of the battery swap trolley 400, the inclined downward air blowing can quickly and completely blow off the impurities on the surface of the battery swap trolley 400, compared with the pure vertical downward air blowing.

[0047] In some embodiments of the present application, as shown in Figure 4 , the battery access port 110 side plate of the battery swap cabinet body is also provided with a rain cover 300, and the rain cover 300 is arranged above the air knife device 200. The rain cover 300 can prevent rain, snow and dust from affecting the air knife device 200, and can protect the air knife device 200, ensuring the reliable operation of the air knife device 200.
