Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] See also Figure 1-Figure 4 The present application provides a housing purge assembly including a fixing mechanism 100 and a purge mechanism 200 .

[0031] See also Figure 1 , 2 and 3, the fixing mechanism 100 includes a bracket 110, a fixing plate 120, an elastic member 130, a clamping plate 140 and a shell 150, the fixing plate 120 is tiltedly arranged on one side of the bracket 110, the elastic member 130 is installed on one side of the fixing plate 120, the clamping plate 140 is arranged on the top of the elastic member 130, and the shell 150 abuts against the inner side of the clamping plate 140.

[0032] In this embodiment, the elastic member 130 includes a fixed rod 131, a spring 132 and a slider 133. The fixed plate 120 is provided with a groove 121. The fixed rod 131 is arranged in the groove 121. The spring 132 is sleeved on the surface of the fixed rod 131. The slider 133 is slidably sleeved on the surface of the fixed rod 131 and abuts against the spring 132. The clamping plate 140 is fixedly connected to the slider 133. By setting the fixed rod 131, the spring 132 and the slider 133, in the absence of external force, the spring 132 elastically recovers and pushes the slider 133 to slide along the fixed rod 131. The slider 133 drives the clamping plate 140 to move, and the clamping plates 140 in the two elastic members 130 are close to each other to clamp the shell 150.

[0033] In a specific embodiment, the clamp 140 is L-shaped, and the open end of the shell 150 is overlapped in the L-shaped clamp 140. By designing the clamp 140 into an L-shape, the open end of the shell 150 can abut against the protruding part, thereby preventing the shell 150 from slipping, and the length of the protruding part is less than the wall thickness of the shell 150.

[0034] In a specific embodiment, every two splints 140 are symmetrically arranged, and a bevel is provided at the end of the splint 140. By providing the bevel at the end of the splint 140, when the shell 150 is inserted, the shell 150 squeezes the bevel, causing the splint 140 to slide to both sides.

[0035] See also Figure 1 , 2 4, the blowing mechanism 200 includes a driving member 210, a cleaning brush 240 and an air blowing pipe 250, the driving member 210 is arranged in the bracket 110, the bottom end of the cleaning brush 240 is fixedly connected to the driving member 210 and the bristle end extends into the shell 150, and the air blowing pipe 250 is arranged on one side of the driving member 210 and faces the shell 150.

[0036] In this embodiment, the driving member 210 includes a threaded rod 211, a driving motor 212 and a moving block 213. The threaded rod 211 is rotatably arranged in the bracket 110, the driving motor 212 is installed on the outside of the bracket 110 and is transmission-connected to the threaded rod 211, the moving block 213 is threadedly sleeved on the surface of the threaded rod 211, and the cleaning brush 240 is fixedly connected to the moving block 213. By setting the threaded rod 211, the driving motor 212 and the moving block 213, the driving motor 212 is started, the driving motor 212 drives the threaded rod 211 to rotate, the threaded rod 211 thread transmission drives the moving block 213 to move, and the moving block 213 drives the cleaning brush 240 to move to clean the inner wall of the shell 150, effectively cleaning the adhered dust and impurities. The driving motor 212 can be a servo motor, which can be adjusted to drive the threaded rod 211 to rotate forward and reverse so that the moving block 213 moves back and forth. The specific principle is conventional technology and will not be described in detail here.

[0037] In a specific implementation, a guide rod 160 is provided in the bracket 110, and the bracket 110 is slidably sleeved on the surface of the guide rod 160. The guide rod 160 is provided to guide the moving block 213 to move linearly to prevent the moving block 213 from rotating during the thread transmission process.

[0038] In this embodiment, the air blowing pipe 250 includes an air guide pipe 251 and a blowing head 252. The air guide pipe 251 is installed on the moving block 213. The blowing head 252 is arranged on one side of the moving block 213 and is connected to the air guide pipe 251. The blowing head 252 opens toward the shell 150. By setting the air guide pipe 251 and the blowing head 252, the air guide pipe 251 is connected to an external ventilation device, and the guide gas is blown out from the blowing head 252 to blow and remove dust from the shell 150.

[0039] The utility model further provides a battery shell cleaning device including the above-mentioned shell purge assembly.

[0040] The working principle of the shell purge assembly and battery shell cleaning device is as follows: when in use, the shell 150 is slid against the fixed plate 120, so that the open end of the shell 150 is pressed against the inclined surface, so that the clamping plate 140 slides to both sides, thereby inserting the shell 150 between the two clamping plates 140. In the absence of external force, the spring 132 elastically recovers and pushes the slider 133 to slide along the fixed rod 131. The slider 133 drives the clamping plate 140 to move, and the clamping plates 140 in the two elastic members 130 are close to each other to clamp the shell 150. At the same time, the shell 150 is sleeved on the cleaning brush 240, and the drive is started. The motor 212 drives the threaded rod 211 to rotate, and the threaded transmission of the threaded rod 211 drives the moving block 213 to move, and the moving block 213 drives the cleaning brush 240 to move to clean the inner wall of the shell 150, effectively cleaning the adhered dust and impurities, and the air guide pipe 251 is connected to the external ventilation equipment, and the guide gas is blown out from the blowing head 252 to blow and remove dust from the shell 150. The inclined fixed plate 120 can make the cleaned dust fall out of the shell 150, thereby facilitating the fixing of the shell 150 in place, and the cleaning effect is also greatly improved.

[0041] It should be noted that the specific model and specifications of the drive motor 212 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0042] The power supply and principle of the driving motor 212 are clear to those skilled in the art and will not be described in detail here.

[0043] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
