The clamping strip 36 and the notch 37 are arranged in a staggered manner with the lug 33 and the clamping block 34, and can be connected with each other in a partial structure.

The lower surface of the battery cover 2 is provided with a clamping part which is clamped with the clamping strip 36, so that the battery cover 2 is connected with the shell 1. The engaging portion includes a vertical engaging portion 22 extending downward in the circumferential direction and the vertical direction of the battery cover, and a horizontal engaging portion 23 extending horizontally below the vertical engaging portion 22, i.e., outward in the radial direction of the battery cover 2.

The battery cover 2 is firstly placed downwards on the accommodating chamber 3 of the shell 1, at this time, the clamping part is firstly positioned in the gap 37, then the battery cover 2 rotates relative to the shell 1, the clamping part gradually rotates to be clamped with the clamping strip 36, at this time, the horizontal clamping part 23 is clamped below the clamping strip 36, the vertical clamping part 22 is positioned at one side of the clamping strip 36, namely, the clamping strip 36 is clamped between the battery cover 2 and the horizontal clamping part 23, and the vertical clamping part 22 is abutted against the side surface of the clamping strip 36. And, the horizontal clamping part 23 and one side end of the vertical clamping part 22 are also provided with a stopper 24 which is vertically arranged and is perpendicular to both the horizontal clamping part 23 and the vertical clamping part 22, when the battery cover 2 rotates to the locking position, the stopper 24 is just clamped at the end of the clamping strip 36.

The vertical clamping part, the horizontal clamping part and the clamping strip are all arc-shaped structures matched with the edge of the battery cover 2 or the peripheral surface 30. The positioning groove 361 is located at one side end of the card strip 36 close to the notch, and the positioning protrusion 221 is also located at one side of the vertical engaging portion 22 close to the tail end of the rotating card, and in order to facilitate the card-in of the positioning protrusion 221, an arc surface 362 is provided at one end of the card strip 36 close to the notch, which is the starting end of the rotating card-in of the engaging portion relative to the card strip.

Although this enables the rotational engagement of the battery cover 2, the battery cover 2 is unlocked by the reverse rotation. Therefore, a locking structure for locking the battery cover 2 and the housing 1 to each other at a locking position needs to be provided on the housing 1. The locking structure comprises a locking member arranged in the housing 1, as shown in fig. 6 and 7, the locking member is arranged inside the housing 1, and comprises a fixed part 41 fixedly connected with the housing 1, an elastic part 42 connected with the fixed part 41, and a locking part 43 connected with the elastic part 42, the elastic part 42 enables the locking part 43 to have a tendency of always being far away from the fixed part 41, and the elastic part 42 is compressed under the action of external force, so that the locking part 43 can be close to the fixed part 41. The upper surface of the locking portion 43 is also provided with a recess 431. Preferably, the elastic portion 42 is a spring sheet that can be folded or unfolded.

The peripheral surface 30 is provided with an opening 38 near the clip strip 36 to expose the locking portion 43 of the locking member. And preferably, the opening 38 is located on the notch 37, and the elasticity of the elastic part 42 makes the locking part 43 have a tendency to always protrude from the opening 38 to the peripheral surface 30, i.e. to protrude into the accommodating chamber 3. The opening 38 is located outside one end of the card strip 36, the opening 38 and the card strip 36 are arranged at an interval, when the battery cover 2 and the housing 1 rotate to the position, the stop 24 is clamped between the end of the card strip 36 and the opening 38, and the locking part 43 of the locking part 4 extends from the opening 38 and is clamped at one side of the stop 24, namely, outside the clamping part, so as to prevent the battery cover 2 from reversely rotating and being pulled out of the housing 1. That is, at this time, the locking member locks the battery cover 2 with the housing 1.

As shown in fig. 6 and 7, a recess 431 is provided above the housing 1, the driving hole 11 exposes the locking portion 43, and when a tool is inserted into the driving hole 11 and then inserted into the recess 431, the locking portion 43 can be driven downward and retracted from the opening 38, and at this time, the locking member can be retracted to the inner side of the peripheral surface 30 and unlocked, so that the battery cover 2 can be rotated reversely relative to the housing 1 at this time.

Since the locking part 43 is exposed to the peripheral surface 30 all the time, the locking part 43 needs to be driven and retracted in the process of locking the battery cover 2 with respect to the housing 1 under normal conditions, which is inconvenient. Therefore, in order to facilitate the locking process on the battery cover, as shown in fig. 7, the outer end surface of the locking part 43 has a tendency to gradually incline from one side to the other side in the horizontal direction, for example, as shown in fig. 3 and 7, the outer end of the locking part 43 includes a slope 432, the slope 432 inclines from the middle to one of the outer ends, and the other end surface of the end is a flat surface, for example, as shown in fig. 7, the slope 432 inclines from the middle to the left side. In this embodiment, a part of the end surface of the outer end of the locking portion is a flat surface, and the other part is an inclined surface inclined from one side to the other side.

Therefore, as shown in fig. 3, when the battery cover 2 is locked by rotating clockwise relative to the housing 1, the inclined surface can drive the locking part 43 to compress the elastic part 42 along with the rotation of the battery cover 2, and then the locking part 43 can automatically retract into the peripheral surface 30, so that the battery cover 2 can be smoothly screwed in and locked, and after the clamping part passes over the locking part 43, the locking part 43 continues to extend out of the peripheral surface 30 under the action of the elastic part, so as to lock the battery cover 2 with the housing 1, and the inclined surface is arranged so that the battery cover 2 can only rotate in one direction relative to the housing 1, and cannot be screwed out of the accommodating chamber 3 in the opposite direction. That is, as in fig. 3, the locking member can prevent the battery lid 2 from being unscrewed counterclockwise with respect to the housing 1, but does not hinder the clockwise screwing of the battery lid 2 with respect to the housing 1.

As shown in fig. 4 and 6, in order to achieve smoother movement of the locking portion 43 protruding forward from the peripheral surface 30 or retracting inside the peripheral surface 30 without shaking left and right, the inside of the opening 38 is provided with a guide surface 381 surrounding the opening 38, along which the movement of the locking portion 43 protruding and retracting moves. The inner bottom of the opening 38 is in inclined-surface engagement with the bottom of the locking portion 43

In the battery cover locking structure, the battery cover 2 can be automatically locked only by being placed into the opening of the battery chamber 3 of the housing 1 and then rotated, and the battery cover is opened relative to the housing, so that the locking part 43 is driven from the driving hole 11 to retract into the peripheral surface 30 to unlock the battery cover 2 and the housing 1, and the battery cover 2 can be opened relative to the housing 1 by rotating the battery cover 2. The two steps of pressing and rotating are operated simultaneously, so that the operation is simple and convenient, and the battery cover is convenient to disassemble relative to the shell and replace the battery; and the locking is firm, and the connection between the battery and the electric contact plate is ensured.
