Description

Technical Field

[0001] The utility model relates to the technical field of backlight components, in particular to a backlight component structure. Background Art

[0002] In the era of rapid development of the Internet, the communication between individuals and society is becoming more and more frequent, and the mature medium of tablet computers is becoming more and more popular among consumers. The development, design and update of the LCM touch module, a key component of its structural hardware, are also becoming faster and faster, and the design requirements of the backlight as an indispensable component are becoming more and more stringent. The conventional backlight structure includes components such as a plastic iron integrated frame, FPC, LED, and light guide plate. It is a common design that the outer wall of the plastic iron frame of the backlight assembly is provided with a groove, and its purpose is to increase space to meet the narrow frame design of the tablet. In the past, the plastic iron frame was only provided with a groove on the outer wall, and the inner wall of the plastic iron frame was a straight edge design. Therefore, the side wall of the light guide plate was also a straight edge design. Under this structural setting, the width of the groove on the outer wall of the plastic iron frame is limited. If the width of the groove on the outer wall of the plastic iron frame is increased, it is easy to cause the outer wall of the plastic iron frame to be too thin and break, and the structural stability is poor; in addition, since the side wall of the light guide plate and the inner wall of the plastic iron frame are both set with straight edges, when the light guide plate is squeezed by the inner wall of the plastic iron frame, it is easy to be squeezed and damaged. Summary of the invention

[0003] The utility model provides a backlight component structure in view of the problems of the prior art. The structure is novel and the design is ingenious. A sufficient space basis is provided for the layout of the camera holes and the structure is reliable. Moreover, since the inner boss and the integrated iron-gluer frame are formed integrally, the structure is stable and the integrated iron-gluer frame will not be broken due to being too thin due to the large width of the outer groove. Direct contact between the inner boss of the integrated iron-gluer frame and the side of the light guide plate during assembly and production is avoided, so that the impact force generated by the contact can be avoided and the light guide plate can be damaged, thereby improving the reliability and stability of the structure.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a backlight component structure, which includes a rubber-iron integrated frame and a light guide plate, the outer side wall of the rubber-iron integrated frame is provided with an outer groove, the inner side wall of the rubber-iron integrated frame is provided with an inner boss, the outer side wall of the light guide plate is provided with an avoidance groove, the outer groove is provided corresponding to the inner boss, and the inner boss is located in the avoidance groove.

[0006] Wherein, the width of the outer groove is 0.4-0.5 mm.

[0007] Wherein, the depth of the outer groove is 1.4-1.6 mm.

[0008] Wherein, the width of the inner boss is 0.2-0.3 mm.

[0009] The integrated iron-plastic frame comprises an outer iron frame and an inner plastic frame, the outer groove is arranged on the outer wall of the outer iron frame, and the inner boss is arranged on the inner wall of the inner plastic frame.

[0010] Wherein, the outer iron frame and the inner plastic frame are integrally injection-molded.

[0011] Beneficial effects of the utility model:

[0012] The utility model has a novel structure and ingenious design. Under the above-mentioned setting, since an inner boss is formed on the inner wall of the rubber-iron integrated frame, the structural width of the outer groove formed on the outer wall of the rubber-iron integrated frame is wider than the width of the outer groove formed by the straight-edge structure of the inner wall of the traditional rubber-iron integrated frame, thereby providing an accommodation space. In the outer groove of the embodiment of the present application, a sufficient space basis is provided for the layout of the camera hole, and the structure is reliable. Moreover, since the inner boss and the rubber-iron integrated frame are formed integrally, the structural stability is strong, and the rubber-iron integrated frame will not be broken due to being too thin due to the large width of the outer groove. In addition, an avoidance groove is provided on the light guide plate at a position corresponding to the inner boss between the light guide plate and the inner wall of the rubber-iron integrated frame, and a gap is formed between the avoidance groove and the inner boss to avoid direct contact between the inner boss of the rubber-iron integrated frame and the side of the light guide plate during assembly and production, thereby avoiding damage to the light guide plate caused by the impact force generated by the contact, thereby improving the structural reliability and stability.
