Referring to fig. 1 to 10, in an embodiment of the present invention, a protective case includes:

the battery compartment 300 and the battery cover provided in example two; the battery compartment body 300 is provided with a second hook structure 310 which is matched with the first hook structure 137; the first hook structure 137 is mated with the second hook structure 310. In this embodiment, two symmetrical second hook structures 310 are provided to mate with a pair of first hook structures 137 on the battery cover; the second hook-shaped structure 310 is similar to the first hook-shaped structure 137 in shape and also comprises a connecting block and a trapezoidal protrusion formed by vertically stretching a right trapezoid, the lower surface of the trapezoidal protrusion is a long bottom side surface, the upper surface of the trapezoidal protrusion is a short bottom side surface, a right-angle waist surface is attached to the top end of the left surface or the right surface of the connecting block, the trapezoidal protrusion of the second hook-shaped structure 310 on the right side is arranged on the top of the left surface of the connecting block and protrudes towards the first end 131 of the corresponding sliding piece 130, the trapezoidal protrusion of the second hook-shaped structure 310 on the left side is arranged on the right side of the top of the connecting block and protrudes towards the first end 131 of the corresponding sliding piece 130, and when in cooperation, the upper surface of the trapezoidal protrusion 137.1 of the first hook-shaped structure 137 is attached to the lower surface of the trapezoidal protrusion of the second hook-shaped structure 310; in order to reduce the reset resistance of the spring, the length of the trapezoidal protrusion of the second hook-shaped structure 310 in the front-back direction is set to be greater than that of the corresponding connecting block in the front-back direction, and the trapezoidal protrusion of the second hook-shaped structure 310 is partially suspended and extended backwards, so that a certain interval exists between the connecting block 137.2 of the first hook-shaped structure 137 and the connecting block of the second hook-shaped structure 310 in the front-back direction, and the contact friction in the matching process can be avoided, thereby reducing the reset resistance.

The battery cover is disassembled: during installation, the battery cover can be aligned with the battery compartment body 300, the inclined surface of the trapezoidal protrusion 137.1 of the first hook-shaped structure 137 is attached to the inclined surface of the trapezoidal protrusion of the second hook-shaped structure 310, then the battery cover is pressed towards the battery compartment body 300, pressing force is transmitted to the first hook-shaped structure 137 through the second hook-shaped structure 310, the pressing force acts on the inclined surface of the trapezoidal protrusion 137.1 of the first hook-shaped structure 137 to generate component force in the stretching direction, so that the spring is compressed, the first hook-shaped structure 137 exits from the matching position, meanwhile, the second hook-shaped structure 310 enters the matching position under the action of the pressing force, at the moment, the pressing force applied to the first hook-shaped structure 137 disappears, the spring resets, and the first hook-shaped structure 137 is pushed to return to the matching position to be matched with the second hook-shaped structure 310, and installation is completed; pressing force can be applied to the two sliding parts 130 at the same time to drive the two sliding parts 130 to approach each other, the first hook-shaped structure 137 exits from the matching position, the covering side of the battery cover is correspondingly attached to the battery compartment body 300 while pressing is kept, the second hook-shaped structure 310 enters the matching position, then pressing on the sliding parts 130 is released, and the first hook-shaped structure 137 returns to the matching position to be matched with the second hook-shaped structure 310 under the action of the restoring elastic force of the spring to complete installation; when the battery is disassembled, pressing force is applied to the two sliding members 130 at the same time to drive the two sliding members 130 to approach each other, and when the sliding members 130 reach the maximum sliding distance, the battery cover is lifted outwards, and is separated from the battery compartment body 300, so that the disassembly is completed.

It introduces to have gone on in detail above the interlocking subassembly, battery cover and protective housing that the utility model provides, to the general technical personnel in this field, according to the utility model discloses the thought of embodiment all has the change part on concrete implementation and application scope, to sum up, this specification content should not be understood as the restriction of the utility model.
