In summary, comparing fig. 4 and fig. 10, and as shown in fig. 7 and fig. 8, the working principle of the present embodiment is as follows:
in an initial state, that is, in a state without external force, in which the unlocking button 42 is not actively forced, the unlocking button 42 is pressed outwards by the second spring 43, and the adjusting rod 41 and the unlocking button 42 are fixedly connected, so that the adjusting rod 41 also moves outwards, and therefore, the reduced diameter part 411 which is arranged at the inner side of the adjusting rod 41, that is, far from the unlocking button 42, simultaneously contacts with the locking member 31, and because the reduced diameter part 411 is small in diameter, the bottom ends of the locking member 31 have a rotation space, and therefore, the top ends of the two locking members 31 simultaneously rotate outwards under the action of the first spring 32, so that the clamping protrusion 311 exceeds the shell 1 and is inserted into the mounting cavity 11;
when the battery pack 2 is inserted, the upper end face of the clamping protrusion 311 is an inclined plane, so that the pressure of the battery pack 2 to the clamping protrusion 311 can separate out a component force in the horizontal direction, thereby driving the top end of the locking piece 31 to rotate inwards, so that the battery pack 2 can be smoothly inserted into the mounting cavity 11, and when the battery pack 2 is completely inserted into the mounting cavity 11, the clamping protrusion 311 can be reinserted into the clamping groove 21 on the battery pack 2 under the action of the first spring 32, and the lower end face of the clamping protrusion 311 is a horizontal plane, and the inner wall face of the lower end of the clamping groove 21 is a horizontal plane, so that the clamping protrusion 311 only receives a horizontal upward acting force, and the clamping protrusion 311 cannot move under the limiting action of the rotating shaft 312, thereby realizing the clamping of the battery pack 2;
when the battery pack 2 is to be taken out, the unlocking button 42 is manually pressed, so that the adjusting lever 41 moves inwards along with the unlocking button 42, the contact position of the locking member 31 and the adjusting lever 41 is stably moved from the reduced diameter part 411 to the expanded diameter part 412 through the connecting part 413, and the expanded diameter part 412 has a larger diameter relative to the reduced diameter part 411, so that the bottom end of the locking member 31 is outwards pushed, namely the top end of the locking member 31 is inwards rotated, at the moment, the first spring 32 is compressed, the clamping protrusion 311 returns to the inside of the shell 1, and therefore, the matching with the clamping groove 21 is disconnected, and the battery pack 2 enters an unlocking state;
when the battery pack 2 is taken out, the unlocking button 42 returns under the action of the second spring 43 after the user releases his hand, the contact position between the adjusting lever 41 and the locking member 31 returns to the diameter-reduced portion 411, and at this time, the clamping protrusion 311 is inserted into the mounting cavity 11 under the action of the first spring 32, so as to be ready for the next clamping with the battery pack 2.
Further, in the present embodiment, the stopper 313 is provided on the locking member 31, and the stopper 313 is adapted to cooperate with the housing 1 to limit the range of outward rotation of the top end of the locking member 31, and the above structure is used to effectively limit the rotation range of the locking member 31 and force the adjusting lever 41 together, thereby improving balance and service life.
Further, in this embodiment, the bottom end of the locking member 31 has a trapezoid structure that gradually becomes smaller from top to bottom. Since the bottom end of the locker 31 is rotated outward by the enlarged diameter portion 412 in use, the above-described structure can effectively prevent the bottom end of the locker 31 from being inserted into the mounting chamber 11 beyond the housing 1 and thus hinder the removal of the battery pack 2.
It should be noted that, in the present embodiment, the axis of the adjusting assembly 4 is perpendicular to the horizontal plane of the limiting assembly 3. That is, as shown in fig. 7, the adjusting component 4 is perpendicular to the axis of the limiting component 3, but not in the same direction, if the adjusting rod 41 needs to pass through between the two locking pieces 31 in the same direction, the first springs 32 cannot be arranged between the two locking pieces 31, and two first springs 32 need to be separately arranged, so that the synchronism and the stability are easily affected.
Further, as shown in fig. 3 and 9, the bottom end of the installation cavity 11 is provided with an ejector structure 5, and the ejector structure 5 is adapted to drive the battery pack 2 to move upward.
In this embodiment, the specific structure of the pop-up structure 5 is: the pop-up structure 5 includes a support block 51 and a third spring 52, the support block 51 being abutted against the bottom end of the battery pack 2 inserted into the mounting chamber 11, and the third spring 52 being disposed between the support block 51 and the housing 1 and adapted to drive the support block 51 to move upward. When entering the unblock state, if not remove battery package 2, in case loose one's hand, joint protruding 311 still can automatic chucking battery package 2, so just need carry and draw battery package 2 when holding release button 42, it is comparatively troublesome, and above-mentioned structure just plays the effect of automatic pop-up, when the unblock state, battery package 2 can oneself upwards move under the effect of pop-up structure 5 to realize the dislocation of chucking protruding and joint groove 21, prevent reentrant locking state, convenience of customers takes off battery package 2.
