[0026] ​The utility model provides a shielding cover, comprising a bracket body 1 arranged on a circuit board and a cover body 2 for closing the bracket body 1; the bracket body 1 comprises a surrounding plate 11 arranged on all sides and an annular structure 12 arranged on the top of the surrounding plate 11, the surrounding plate 11 is provided with a first through hole 111, and the annular structure 12 is provided with a second through hole 121; the cover body 2 is provided with a hook structure 21 that cooperates with the first through hole 111, the hook structure 21 is arranged perpendicular to the cover body 2, and the cover body 2 is also provided with a buckle structure 22 for inserting into the second through hole 121 during installation.

[0027] Specifically, the design of the bracket body 1 and the cover body 2 makes the installation and removal process easier. Furthermore, the hook structure 21 and the buckle structure 22 in this embodiment can easily connect the cover body 2 to the bracket body 1, and the cover body 2 can be quickly opened to maintain or replace the internal electronic equipment such as the circuit board when necessary. At the same time, since the hook structure 21 and the buckle structure 22 are a compact design, the space can be effectively utilized and will not take up too much extra space, which is particularly beneficial for application scenarios with limited space.

[0028] In this embodiment, undercut grooves 221 are provided on both sides of the buckle structure 22, and the undercut grooves 221 abut against the edge of the second through hole 121. The design of the undercut grooves 221 enables the buckle structure 22 to abut against the edge of the second through hole 121 on the bracket body 1, thereby providing additional support and stability. When the cover body 2 is installed on the bracket body 1, the abutment between the undercut grooves 221 and the edge of the hole can ensure the accuracy of the position of the cover body 2 and prevent movement or loosening during use.

[0029] In one embodiment, the hook-shaped structure 21 includes an abutment sheet 211, which is a sheet-shaped structure. The abutment sheet 211 elastically abuts against the enclosure 11, and the end of the abutment sheet 211 is provided with a hook portion 212 for extending into the first through hole 111. The abutment sheet 211 elastically abuts against the enclosure 11, so that the hook-shaped structure 21 can be firmly connected to the enclosure 11, ensuring the firmness of the connection, reducing the looseness or movement that may occur during use, and thus improving the stability of the shielding cover. In addition, since the hook-shaped structure 21 is elastic and the end of the hook-shaped structure 21 is provided with a hook portion 212 for extending into the first through hole 111, during installation, it is only necessary to insert the hook portion 212 into the first through hole 111 to complete the connection. This saves time and labor costs, making the installation process more convenient.

[0030] In another embodiment, the hook structure 21 includes a bending piece 213, the bending piece 213 elastically abuts against the enclosure 11, and the end of the bending piece 213 is provided with a bending portion 214 for extending into the first through hole 111, and the bending direction of the bending portion 214 is opposite to the bending direction of the bending piece 213. The bending piece 213 clings to the surface of the enclosure 11 through its elastic properties, ensuring a firm connection with the enclosure 11, enhancing the firmness of the connection, and reducing possible loosening or movement during use. In addition, the end of the bending piece 213 is provided with a bending portion 214, and the design of the bending portion 214 enables it to extend into the first through hole 111 to achieve connection with the bracket body 1. Compared with the hook portion 212, the design of the bending portion 214 is more flexible and adaptable, and can better adapt to holes of different shapes and sizes.

[0031] In another embodiment, a plurality of the first through holes 111 are provided, and the number of the hook-shaped structures 21 corresponds to the number of the first through holes 111, and the hook-shaped structures 21 are located at the edge of the cover body 2.

[0032] Further, in this embodiment, the hook structure 21 includes an abutting piece 211 and a bending piece 213. The abutting piece 211 is a sheet-like structure. The abutting piece 211 elastically abuts against the enclosure 11, and the end of the abutting piece 211 is provided with a hook portion 212 for extending into the first through hole 111. The bending piece 213 elastically abuts against the enclosure 11, and the end of the bending piece 213 is provided with a bending portion 214 for extending into the first through hole 111, and the bending direction of the bending portion 214 is opposite to the bending direction of the bending piece 213.

[0033] In this embodiment, a plurality of the second through holes 121 are provided, and the number of the buckle structures 22 corresponds to the number of the second through holes 121.

[0034] In this embodiment, the cover body 2 is also provided with a plurality of convex bumps 23, which are used to provide a supporting force away from the installation direction of the cover body 2. The distribution of the convex bumps 23 is designed to evenly cover the entire interface of the cover body 2, thereby ensuring that the pressure applied during connection is evenly distributed, which helps to reduce local stress concentration and improve the stability and reliability of the connection.

[0035] In this embodiment, a positioning block 24 is vertically extended on the cover body 2, and a first positioning hole 241 for a positioning pin to pass through is formed on the positioning block 24, and a second positioning hole 112 corresponding to the first positioning hole 241 is formed on the enclosure 11.

[0036] The above are only alternative embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present utility model under the inventive concept of the present utility model, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present utility model.
