As shown in fig. 1, 2 and 3, the lifting mechanism in this embodiment includes a driving rack 5, a driven rack 6 and a reversing gear 7, where the driving rack 5 and the reversing gear 7 are vertically arranged in parallel, the top end of the driving rack 5 is fixed on the bottom surface of the pressing plate 2, one end of a fixed shaft 8 of the reversing gear 7 is fixed on the side wall of the housing 1, the other end faces the cover 10, the driven rack 6 is arranged on the housing 1 in a sliding manner up and down, the reversing gear 7 is respectively meshed with the driving rack 5 and the driven rack 6, the hook 3 is arranged on the driven rack 6, the pressing plate 2 is in an initial state of the fastening mechanism when not pressed, and in the initial state, the lower end of the driving rack 5 in this embodiment is meshed with the reversing gear 7, and the upper end of the reversing gear 7 is meshed with the reversing gear 7. In this embodiment, since the reversing gear 7 is disposed between the driving rack 5 and the driven rack 6, the moving directions of the driving rack 5 and the driven rack 6 are always opposite, so that it is ensured that the hook 3 moves upward along with the driven rack 6 after the pressing plate 2 is pressed, and it is ensured that the pressing plate 2 moves downward after the pressing plate 2 is released by the reset spring 9 after the pressing plate 2 is lifted and reset.
As shown in fig. 1 and 4, the back of the driving rack 5 is propped against the stiffening beam 21, the top end of the stiffening beam 21 is integrated with the pressing plate 2, the stiffening beam 21 increases the stability of the driving rack 5, as shown in fig. 6, a guide convex plate 23 is arranged on the surface of the stiffening beam 21 adjacent to the shell 1, as shown in fig. 1 and 4, a guide groove 22 with an open bottom end is arranged on the side wall of the shell 1, the guide groove 22 is formed by two vertically arranged plate bodies, the guide convex plate 23 is inserted into the guide groove 22, so that the stiffening beam 21 is limited and guided by the guide groove 22, the stiffening beam 21 runs more stably, and further, the driving rack 5 is prevented from shaking to influence the meshing transmission of the reversing gear 7.

As shown in fig. 1, 2 and 3, a return spring 9 is disposed between the pressing plate 2 and the housing 1 in this embodiment, specifically, a horizontal return plate 16 is disposed in the housing 1, as shown in fig. 1 and 3, the return plate 16 may be an inverted L-shaped, a vertical plate 162 forming an inverted L-shape is connected with the housing 1 by means of screws or adhesion, as shown in fig. 1 and 2, a lower connecting post 18 is disposed on the upper surface of the vertical plate 162 forming an inverted L-shape, an upper connecting post 17 is disposed on the bottom surface of the pressing plate 2, and the upper and lower ends of the return spring 9 are respectively fixed on the upper and lower connecting posts 17 and 18, so that when the pressing of the pressing plate 2 is released, the pressing plate 2 is sprung upward under the action of the return spring 9 to return. Two return springs 9 are symmetrically arranged on the vertical plate 162.
As shown in fig. 1 and 6, the left and right ends of the pressing plate 2 in the present embodiment extend outwards to form a shoulder 11, and the shoulder 11 is lower than the top surface of the pressing plate 2 and is located below the top plate of the housing 1, so that the pressing plate 2 is disposed on the top of the housing 1, and the pressing plate 2 is prevented from being separated from the housing 1 when rebound and rising under the action of the return spring 9.
The working process comprises the following steps:
when the battery converter is installed, as shown in fig. 1, 2 and 3, the pressing plate 2 is pressed down, the driving rack 5 moves downwards along with the pressing plate 2 to drive the reversing gear 7 to rotate, then the reversing gear 7 drives the driven rack 6 to move upwards, the clamping hook 3 on the driven rack 6 moves upwards along with the reversing gear 6 to be horizontally aligned with a clamping groove formed in the shell of the battery, meanwhile, the shell 1 is pushed to move towards the shell of the battery, so that a contact pin arranged on the battery converter is matched with a jack formed in the shell of the battery, the battery converter is electrically connected with the battery, the battery converter is contacted with the shell of the battery, the clamping hook 3 is inserted into the clamping groove, then the pressing plate 2 is released, the pressing plate 2 is sprung upwards to reset under the action of the reset spring 9, the driving rack 5 moves backwards along with the pressing plate 2 to rotate reversely to enable the driven rack 6 to descend, and finally the clamping hook 3 descends to hook the edge of the clamping groove;
when the battery converter is pulled out, as shown in fig. 1, 2 and 3, the pressing plate 2 is pressed down, the driven rack 6 is driven to move upwards by the driving rack 5 through the reversing gear 7, so that the clamping hook 3 moves upwards again to be opposite to the bayonet, the battery converter is pulled out outwards at the same time, the clamping hook 3 comes out from the bayonet, the pressing plate 2 is loosened, the pressing plate 2 is reset to drive the clamping hook 3 to descend to restore to the initial state, and the separation of the battery converter and the battery is completed.
