Outer frame of backlight module unit

Abstract

The invention discloses an outer frame of a backlight model, comprising an upper frame and a backing plate; wherein, the upper frame is provided with a first upper frame side, two second upper frame sides and two pivotal parts, and the two second upper frame sides are mutually parallel and vertical to the first upper frame side; the two pivotal parts are respectively arranged at the two second upper frame sides. The backing plate is provided with a first backing plate side, two second backing plate sides and two coupling parts, wherein, the two second backing plate sides are mutually parallel and vertical to the first backing plate side, and the two coupling parts are respectively arranged at the two backing plate sides. The two pivotal parts of the upper frame and the two coupling parts of the backing plate are corresponding to each other and connected with each other to form two pivot structures.

Description

【Technical field】 [0001] The present invention relates to an outer frame of a backlight module, in particular to an outer frame structure of a detachable backlight module. 【Background technique】 [0002] Backlight modules are usually used in liquid crystal displays to provide light sources for them. The outer frame of the backlight module is usually interlocked with the upper frame and the back plate to fix the components installed inside the outer frame. During the assembly process, it is unavoidable to need to rework and rework to open the frame. Therefore, whether the design of the assembly structure of the backlight module frame is easy to assemble and disassemble will seriously affect the finished product yield and production speed. [0003] The assembly structure of the frame of the traditional backlight module is mostly designed as a hook-type positioning, wherein a considerable number of hooks are used. figure 1 2 shows a three-dimensional schematic diagram of the ...

Problems solved by technology

[0004] For the hook-type assembly structure mentioned above, in order to ensure the compactness of the whole structure and fit in place, the fit size of the hook and the square hole is often designed to be relatively compact, which will make it very difficult for the operator to disassemble, and the entire backlight module needs to be lifted. High, which increases the complexity of the operation and is easy to cause fatigue to the operator. If the operation is careless, it will cause the optical film (Optic Films) of the display to shift up and down or collide with scratches and other adverse consequences, thereby reducing the yield of the production line and increasing the manufacturing capacity. cost
