Description

Technical Field

[0001] The utility model relates to the technical field of optoelectronic devices, in particular to a watch display screen cover. Background Art

[0002] The watch display cover is a component that covers the watch display. Its main function is to protect the display as a barrier to prevent scratches and wear, avoid friction damage during daily contact, and prevent dust and moisture from entering, isolating and protecting the internal display components. The second function is to optimize optical performance, reduce external light reflection, and make the screen content clearer and easier to read under various lighting conditions. Some covers have anti-glare coatings to reduce interference from strong light. The third function is exterior decoration. Through various surface treatments such as mirror and frosted finishes, different visual effects are created to match the overall style of the watch, thereby enhancing the watch's beauty and texture.

[0003] Existing technologies include the utility model with publication number CN219349365U, which discloses a watch touch screen cover, including a touch screen cover body installed inside a shell, the touch screen cover body consisting of a touch screen body and a cover body, the touch screen body is arranged on the rear surface of the cover body, and a locking mechanism is provided at the locking position between the cover body and the shell, the locking mechanism consisting of a locking assembly, a limiting assembly, and a connecting assembly; the designed locking mechanism is used to improve the installation between the original touch screen cover body and the shell, and is fixed by colloid adhesion. Since the viscosity of the colloid will decrease after long-term use of the watch, the locking and limiting structure is added to the original fixation of the touch screen cover body and the shell. While ensuring the convenience of operation, the connection stability between the two is increased, which plays a role of secondary reinforcement and ensures the stability of the watch during use.

[0004] Currently, most watches are assembled through a snap-fit ​​structure of glue and bolts. When disassembling and maintaining, the operation is cumbersome, which increases the difficulty of installing and maintaining the display cover, and is not conducive to the normal use of the display cover.
