Outer frame of backlight module unit

Abstract

The invention discloses an outer frame of a backlight module, comprising a first frame and a second frame. The first frame is provided with a first edgefold and a first opening. The first edgefold has a bottom edge, a first hook and a second hook. The first opening is concavely arranged to the inside of the first edgefold from the bottom edge. The first hook and the second hook extend towards the bottom edge and extend into the first opening. The second frame is provided with a second edgefold and a second opening arranged on the second edgefold. The second edgefold has a lock portion above the second opening. The lock portion has a top wall, a first side wall and a second side wall. The first side wall and the second side wall are arranged oppositely and extend upwards from the second edgefold. The top wall is connected with the first side wall and the second side wall and arranged above the second opening. The first hook and the second hook are respectively matched with the first side wall and the second side wall.

Description

【Technical field】 [0001] The invention relates to an outer frame of a backlight module, in particular to an outer frame of a detachable backlight module. 【Background technique】 [0002] The outer frame of the backlight module usually includes a plastic frame and a back plate, and the plastic frame of the back light module outer frame and the back plate are processed to form an engaging structure that can be buckled with each other. In this way, the back light module can be fixed internal materials. Therefore, whether the design of the outer frame of the backlight module is easy to assemble and disassemble and whether the fixing method is good will seriously affect the yield rate of finished products and the production speed. [0003] The outer frame of the existing backlight module is mostly designed as an external hook-type positioning. figure 1 shows a three-dimensional structure schematic diagram of an existing outer snap-hook type plastic frame and a backplane engaging...

Problems solved by technology

[0005] In addition, in order to ensure that the entire clamping structure is compact and fit in place, the hook-type clamping structure often designs the matching size of the hook on the backplane and the square hole of the plastic frame to be relatively compact, which will make it very difficult for the operator to disassemble. The entire engaging structure needs to be raised, which increases the complexity of the operation and is easy to cause fatigue to the operator. If the operation is not careful, it will cause the optical film (Film) of the display to shift up and down or collide and scratch the screen. Reduce production line yield and increase manufacturing costs
