In the present embodiment, it is preferable that: when the battery pack is used, the battery pack is placed and the air cylinder 2 is started to drive the base 301, the shell 302, the first sliding block 401, the wedge block 404, the gear 405, the short rod 501, the third sliding block 601 and the plug 8 to synchronously move towards the direction of the battery pack; in the moving process, the effective positioning of the plug 8 and the socket in the horizontal direction can be realized through the matching of structures such as the inclined plane of the wedge block 404, the left side and the right side of the socket, the second spring 402, the shell 302 and the like; after the horizontal positioning of the plug 8 is finished, with the continuous movement of the action of the cylinder 2, the second rack 602 and the third slider 601 are driven to slide out of the shell 302 through the matching of the structures such as the convex connecting rod 503, the surface of the battery pack, the first rack 506 and the gear 405, the third slider 601 drives the guide rod 603 to move synchronously, so that the guide rod 603 moves to be attached to the corresponding baffle 304, and at the moment, the plug 8 is driven to move synchronously through the matching of the structures such as the inclined plane of the third slider 601, the upper side and the lower side of the socket, the shell 302 and the base 301, and the like, so that the effective positioning in the vertical direction of the socket is realized; then, the wedge-shaped block 404 is abutted against the surface of the battery pack and matched with the workbench 1 to realize effective positioning of the battery pack in the front-back direction, and at the moment, the plug 8 can be accurately inserted into the socket and the test is started.
After the test is finished, the air cylinder 2 drives the base 301, the shell 302, the plug 8 and the baffle 304 to reset, and the wedge-shaped block 404 and the connecting rod 503 still abut against the surface of the battery pack under the action of the third spring 403, so that a part of power is provided for the quick separation of the socket and the plug 8; the baffle 304 drives the third slider 601 and the second rack 602 to move synchronously through the guide rod 603, the second rack 602 drives the first rack 506 to move towards the direction far away from the housing 302 through the gear 405, the first rack 506 drives the connecting rod 503 to rotate towards the direction far away from the housing 302 (i.e. towards the battery pack) through the cooperation of the structures such as the second slider 505, the crank 504, the torsion spring 502 and the short rod 501, and the like, so that the reverse pushing force to the battery pack is increased, and the socket can be separated from the plug 8 more quickly; after the plug 8 is separated from the socket, with the continued movement of the housing 302, the baffle 304, the guide rod 603 and the third slider 601, the third spring 403 has been restored to the original state, at this time, the first slider 401, the gear 405, the wedge-shaped block 404, the groove 406, the short rod 501 and the link 503 start to be reset, at this time, the first rack 506, the gear 405 and the second rack 602 keep moving synchronously, and the second rack 602 drives the third slider 601 and the guide rod 603 to retract into the housing 302 to complete the reset.
In the second embodiment, although the wedge-shaped block 404 and the link 503 are abutted against the surface of the battery pack to provide a reverse thrust for the separation of the plug 8 and the socket in the later period, the reverse thrust is based on the elastic supporting force of the third spring 403, the thrust is limited, the burden on the third spring 403 is large, and certain use limitation exists. Compared with the second embodiment, through the matching of the structures of the shell 302, the baffle 304, the guide rod 603, the first rack 506 and the like, in the resetting process after the test is finished, the connecting rod 503 can be driven to rotate towards the battery pack, so that the end part of the connecting rod 503, which is far away from the short rod 501, extrudes the surface of the battery pack, increases the reverse pushing force on the battery pack, and is matched with the wedge-shaped block 404 and the third spring 403, so that the socket can be separated from the plug 8 more quickly, the stable separation of the plug 8 and the socket is further ensured, the acting force on the third spring 403 is also reduced, and the service life of the third spring 403 is prolonged; meanwhile, the reset strokes of the connecting rod 503 and the crank 504 are better utilized, the overall functionality of the transmission assembly 5 is improved, and the applicability is stronger.
The working principle of the invention is as follows: when the battery pack is used, the battery pack is placed on the workbench 1, the socket on the battery pack is opposite to the plug 8, and then the cylinder 2 is started to drive the base 301, the first sliding block 401, the wedge-shaped block 404, the gear 405, the short rod 501, the third sliding block 601 and the plug 8 to synchronously move towards the direction of the battery pack; in the moving process, the effective positioning of the plug 8 and the socket in the horizontal direction can be realized through the matching of structures such as the inclined plane of the wedge block 404, the left side and the right side of the socket, the second spring 402, the shell 302 and the like; after the horizontal positioning of the plug 8 is finished, the plug 8 is driven to synchronously move along with the continuous movement of the action of the cylinder 2 through the matching of the structures such as the convex connecting rod 503, the surface of the battery pack, the first rack 506 and the gear 405 to drive the second rack 602, the third slider 601 and the guide rod 603 to move towards the direction far away from the shell 302 until the guide rod 603 is attached to the corresponding baffle 304, and at the moment, through the matching of the structures such as the inclined plane of the third slider 601, the upper side and the lower side of the socket, the shell 302 and the base 301, the plug 8 is driven to synchronously move to realize the effective positioning with the socket in the vertical direction; then, the wedge-shaped block 404 is abutted against the surface of the battery pack and matched with the workbench 1, so that the effective positioning in the front-back direction of the battery pack can be realized, and at the moment, the plug 8 can be accurately inserted into the socket and the test is started.
After the test is finished, the air cylinder 2 drives the base 301, the shell 302, the partition plate 7 and the plug 8 to move in advance, and under the action of the third spring 403, the wedge-shaped block 404 and the connecting rod 503 still abut against the surface of the battery pack to provide a part of power for the quick separation of the socket and the plug 8; the baffle 304 drives the third slider 601 and the second rack 602 to move synchronously through the guide rod 603, and the second rack 602 drives the connecting rod 503 to rotate towards the battery pack to extrude the battery pack through the matching of the gear 405, the first rack 506, the second slider 505, the crank 504 and other structures, so that the reverse pushing force to the battery pack is increased, and the socket can be separated from the plug 8 more quickly; after the plug 8 is separated from the socket, with the continued movement of the housing 302, the baffle 304, the guide rod 603 and the third slider 601, the third spring 403 has been restored to the original state, so that the first slider 401, the gear 405, the wedge-shaped block 404, the short rod 501, the connecting rod 503, the first rack 506, the gear 405, the second rack 602, the third slider 601 and the guide rod 603 complete the reset, and then the housing 302 also automatically resets under the action of the first spring 303, so that the whole set of test work of the battery pack is completed, and the test work is repeated.
