In order to ensure the connection between the battery cover 2 and the housing 1 at each segment and improve the installation stability and the sealing performance between the battery cover 2 and the housing 1, please refer to fig. 1 and 5, in this embodiment, a battery fixing cavity 12 located at the rear side of the cover plate connecting cavity 11 is further formed on the upper end surface of the housing 1, and the battery cover 2 is formed with a cover section 22 covering the battery fixing cavity 12; the fixing structure 3 of the battery cover and the shell further comprises a reinforcing and fixing component 35, wherein the reinforcing and fixing component 35 comprises a reinforcing and positioning part arranged on the lower end face of the battery cover 2 and a reinforcing and matching part arranged on the upper end face of the shell 1; so set up, when battery cover 2 activity extremely when fixed position, consolidate the location portion with consolidate the cooperation portion and mutually support to in the fastening connection from top to bottom battery cover 2 with casing 1, and then guaranteed longer the section 22 is established to the lid also can fastening connection to casing 1.

Further, referring to fig. 1, fig. 3 and fig. 5, in the present embodiment, the reinforcing positioning portion is a reinforcing protrusion 351, the reinforcing protrusion 351 has a vertical connecting section and a horizontal fixing section, the upper end of the vertical connecting section is connected to the lower end surface of the battery cover 2, the horizontal fixing section is formed at the lower end of the vertical connecting section and extends rearward, the reinforcing matching portion is a reinforcing groove 352, the reinforcing groove 352 has a vertical opening groove section and a horizontal matching groove 322 section, the vertical opening groove section penetrates upward to the upper end surface of the housing 1, and the horizontal matching groove 322 section is connected to the lower end of the vertical opening groove section and extends rearward; wherein the lateral fixing section of the reinforcing protrusion 351 is fittingly installed with the lateral fitting groove 322 section of the reinforcing groove 352. So set up, consolidate lug 351's horizontal fixed segment is earlier through vertical opening groove activity extremely the front side opening position of horizontal cooperation groove, then be in battery cover 2 is the adaptation card is gone into under the drive of back activity horizontal cooperation groove, in order to realize the lid is established section 22 and is stabilized the lid and locate battery fixed cavity 12, simple structure, the effect is outstanding.

In other embodiments, the reinforcing protrusion 351 may also be a trapezoidal block, and in the direction from the front to the back, the rear side of the trapezoidal block is disposed obliquely downward, correspondingly, the rear side of the reinforcing groove 352 is disposed obliquely corresponding to the rear side of the trapezoidal block, so that the reinforcing protrusion 351 and the rear side of the reinforcing groove 352 are abutted against each other and matched, and the cover setting section 22 can be stably covered and disposed in the battery fixing cavity 12.

In another embodiment, the reinforcing and positioning portion and the reinforcing and positioning portion may also be opposite magnetic poles that attract each other, and when the battery cover 2 moves to the fixed position, the reinforcing and positioning portion and the reinforcing and positioning portion are located at the position where the attraction force between them is strongest, so that the battery cover 2 and the housing 1 are connected and fastened.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
