electronic device

technical field

The utility model relates to an electronic device; specifically, the utility model relates to an electronic device which uses a special spring sheet structure to engage the outer frame.

Background technique

Most of the design focus of general monitors is mainly on narrowing the front side and thinning the side, as well as the appearance and texture of the front and side.

The front frame of the display is mainly designed with side lock screws (hooks) or back lock screws. In order to beautify the lock hole, it may be covered with a decorative piece. The back panel is exposed as an exterior. Basically, the fixing method will affect the appearance, and must also take into account the appearance, reliability, and reworkability. If you want to avoid screw exposure, the design of using hooks or adhesives must also consider the size and reliability. Even if it is assembled It is firm and sticky enough, and the heavy industrial performance encountered in mass production is also a major factor affecting product design.

The frame (front frame or rubber frame) is designed with hooks alone, as long as the gap is properly designed, it can be locked quite firmly, but it may encounter some problems in heavy work. For example, the tightness of the card is usually equal to the difficulty of removal, and the hooks of the same frame must be released at the same time to disassemble, if they are released separately, they will still be stuck back. Another problem is the structure of the hook structure. During the disassembly process, due to external force, it may be deformed and then permanently deformed. Therefore, the reworkability is not good, and the heavy-duty products may be damaged and cannot be reused. Furthermore, many fixing methods in the backlight module need to be fixed by individual structures, such as optical films, diffusion plates, etc., but due to the influence of thinning and narrowing, it is limited to accommodate too complicated structures.
