[0004] The purpose of this invention is to provide a stepped light guide plate for a keyboard backlight module to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stepped light guide plate for a keyboard backlight module, comprising a mounting frame and a light guide plate body. The mounting frame has a bearing groove on its inner sidewall, and the light guide plate body is slidably inserted into the bearing groove. One end of the mounting frame is fixedly connected to two symmetrically arranged shafts, and one end of each shaft is fixedly connected to a swing plate. One end of the swing plate is provided with a traction plate, and the swing plate and the traction plate are hinged together by multiple torsion spring shafts. The bottom of the traction plate is fixedly connected to a positioning plate, and the positioning plate is inserted into the bearing groove and abuts against the light guide plate body.

[0006] As a preferred embodiment of this utility model, a stop rod is slidably inserted into the other end of the swing plate, and the mounting frame is provided with stop grooves corresponding to the stop rod on both outer walls of the shaft.

[0007] As a preferred embodiment of this invention, the plurality of torsion spring shafts are equidistant from each other.

[0008] In a preferred embodiment of this invention, one end of the bearing groove is connected to the mounting frame.

[0009] As a preferred embodiment of this utility model, one end of the stop rod is fixedly connected to an anti-detachment block, and a spring is sleeved on the stop rod, with both ends of the spring fixedly connected to the anti-detachment block and the swing plate, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This keyboard backlight module uses a stepped light guide plate. By flipping the traction plate, the torsion spring shaft rotates, causing the positioning plate to detach from the bearing groove. Then, the rotating swing plate rotates around the shaft, placing the positioning plate outside the bearing groove. Subsequently, the light guide plate body is inserted into the bearing groove on the mounting frame. Then, the swing plate is rotated in the opposite direction, so that the positioning plate is on one side of the light guide plate body. The rotational torque of the torsion spring shaft causes the positioning plate to snap into the outside of the light guide plate body, thus fixing the light guide plate body. This utility model facilitates the easy installation and removal of the light guide plate, and the installation and removal process does not require the use of tools, which speeds up the disassembly efficiency of the device and improves the functionality of the device.
