Description

Technical Field

[0001] The utility model relates to the technical field of backlight modules, in particular to a fixing structure for a vehicle-mounted backlight module. Background Technique

[0002] At present, the lower iron frame of the die-cast backlight module is usually adopted. This is because the die-casting injects the molten metal into the mold under high pressure and cools and forms. It can integrally form the backlight lower iron frame and the external installation housing, making the structural stability higher.

[0003] In the related art, the backlight film of the conventional backlight module is fixed by double-sided adhesion on the light guide plate. The border of the corresponding display module is relatively wide in this way. However, for a display module with a narrow border, in order to ensure the viscosity of the double-sided adhesion, the double-sided adhesion will be relatively wide, and then the double-sided adhesion is too close to the viewing area of the display module, so that the display module may have a bright line situation. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a fixing structure for a vehicle-mounted backlight module, which can ensure the stable fixing of the backlight film while ensuring the normal display of the display module.

[0007] The width of the convex platform is smaller than the width of the receiving groove.

[0008] A groove is opened on the housing.

[0009] The backlight assembly includes an FPC board, and the FPC board is arranged in the groove.

[0010] A chamfered portion is arranged at the bottom of the receiving groove.

[0011] A support arm is further arranged on the housing, and the support arm is connected to the convex block.

[0012] A clamping groove is further opened on the housing.

[0013] A limiting groove is further opened on the housing.

[0014] The length of the glue body is the same as the length of the convex platform.

[0015] A holding groove is also formed on the outer shell.

[0016] Compared with the prior art, the present utility model has at least the following advantages:

[0017] The boss is a part where the backlight film extends. Then, a receiving groove is formed on the bump of the outer shell, and the fixing position of the boss is extended to the receiving groove, thereby lengthening the distance from the adhesive colloid to the viewing area and avoiding the possible occurrence of bright lines in the display module.
