AI Technical Summary

Technical Problem

The lack of positioning reference during the assembly process of COF structure circular screen leads to a high risk of assembly deviation. In addition, the connection and debugging board needs to be installed inside the equipment, which occupies a lot of space, making installation difficult, especially in situations with limited space.

Method used

Design a circular screen self-locking structure, including a plastic shell and a snap-fit ​​structure. The plastic shell wraps around the COF structure circular screen and has a groove on the side near the screen to adhere it firmly. The snap-fit ​​structure can move slightly and be embedded in the device shell to provide positioning and self-locking functions. The device shell is slightly larger than the plastic shell to ensure accurate positioning.

Benefits of technology

It achieves a stable connection of COF structure circular screens, avoids assembly deviations, improves assembly accuracy and efficiency, saves internal space of equipment, facilitates the installation of debugging boards, and enhances product applicability.

Abstract

The utility model relates to a kind of round screen self-locking structure, including round screen whole and equipment shell;Round screen whole is composed of COF structure round screen, plastic shell and debugging board.Liquid crystal is wrapped COF structure round screen by plastic shell side wrapping screen, and the recess for sticking firm COF structure round screen is provided in the wire arrangement position and is hollowed out;There is movable arch-like buckle outside, and the side of buckle close to screen has ridge, and the other side is smooth;Far from screen side is equipped with the structure of locking debugging board;Equipment shell hollow size is slightly larger than the actual size of plastic shell (except buckle position);When assembling, positioning is carried out through buckle, buckle is embedded in equipment shell, and equipment shell is clamped on ridge to realize self-locking;The structure solves the problem that COF structure round screen installation has no positioning reference and is easy to install deviation, and debugging board is difficult to install when in the limit of equipment internal space, with the advantages of accurate assembly, strong space adaptability etc.
