Description

Technical Field

[0001] The utility model relates to the field of display screen accessories, in particular to a backlight structure for preventing the backlight from loosening. Background Art

[0002] With the continuous development of LCM displays, customers have increasingly higher requirements for the mechanical properties of products. Impact resistance tests are added on top of conventional drop tests and vibration tests. This places more stringent requirements on the matching structure inside the display. For example, the backlight cannot be loose at all, because the backlight not only provides light source for the LCD but also is an important carrier of structural strength. Against this background, a glue-iron frame matching structure that prevents backlight loosening was born.

[0003] The conventional design placed a back frame positioning slot at the bottom of the plastic frame, with the back frame positioned within it. This single-pair design caused the plastic frame to loosen when subjected to outward force. However, conventional LCM displays masked this loosening by applying adhesive around both the plastic and metal frames. With the changing market environment, LCM displays face stringent cost requirements, and eliminating adhesive has become a key cost-reduction measure. Therefore, how to ensure a good fit between the plastic and metal frames without adhesive, thus preventing loosening, became a new research topic. Utility Model Content

[0005] The technical solution adopted to solve the technical problem raised by the utility model is as follows: the backlight structure of the utility model for preventing the backlight from loosening includes a plastic frame, a display module, a back frame and a backlight module, the back frame is connected to the bottom of the plastic frame, a backlight module mounting groove is provided in the back frame, the backlight module is located in the backlight module mounting groove, a display module mounting groove is opened on the top of the plastic frame, the display module is located in the display module mounting groove, a back frame positioning groove is provided at the bottom of the plastic frame, the back frame is located in the back frame positioning groove, the back frame is clamped with the back frame positioning frame, the top surface of the back frame is fitted with the bottom surface of the back frame positioning groove, vertical plug-in plates are provided around the bottom of the plastic frame, and the vertical plug-in plates are located on the inner side of the back frame side wall.

[0006] The technical solutions that further define the utility model include:

[0007] A back frame buckle is provided on the outer side of the back frame side wall, and a back frame clamping groove is provided on the side wall of the back frame positioning groove to cooperate with the back frame buckle.

[0008] The side walls of the back frame are provided with outwardly protruding plug-in plate positioning grooves corresponding to the vertical plug-in plates.

[0009] Through the above technical scheme, the beneficial effects of the utility model are as follows: the bottom of the rubber frame of the backlight structure of the utility model that prevents the backlight from loosening is provided with a back frame positioning groove, the back frame is located in the back frame positioning groove, the back frame and the back frame positioning frame are clamped, the top surface of the back frame is fitted with the bottom surface of the back frame positioning groove, and vertical plug-in plates are provided around the bottom of the rubber frame, and the vertical plug-in plates are located on the inner side of the back frame side wall. Therefore, when the rubber frame is subjected to force, the vertical plug-in plates around it are inserted into the inner side of the back frame side wall, thereby preventing the rubber frame from turning outward, and at the same time reducing the process of attaching the edging glue, thereby playing a role in reducing costs and increasing efficiency.

[0014] The structure of the present invention is further described below with reference to the accompanying drawings.

[0015] Reference Figures 1 to 4The backlight structure for preventing backlight loosening of the present invention includes a plastic frame 1, a display module, a back frame 2, and a backlight module. The back frame is connected to the bottom of the plastic frame. A backlight module mounting groove is provided in the back frame. The backlight module is located in the backlight module mounting groove. A display module mounting groove 11 is provided at the top of the plastic frame 1. The display module is located in the display module mounting groove. A back frame positioning groove 12 is provided at the bottom of the plastic frame. The back frame is located in the back frame positioning groove. The back frame and the back frame positioning frame are clamped together. In this embodiment, a back frame buckle 21 is provided on the outer side of the side wall of the back frame 2. A back frame clamping groove 121 that cooperates with the back frame buckle is provided on the side wall of the back frame positioning groove 12. When the back frame is placed in the back frame positioning groove, the back frame buckle is engaged with the back frame clamping groove, and the back frame and the plastic frame are clamped together. The top surface 22 of the back frame fits in with the bottom surface 122 of the back frame positioning groove, so that the back frame provides stable support for the rubber frame. Vertical plug-in plates 13 are provided around the bottom of the rubber frame 1, and the vertical plug-in plates are located on the inner side of the side wall of the back frame. Therefore, when the rubber frame is subjected to force, the vertical plug-in plates on all sides are inserted into the inner side of the back frame side wall, thereby preventing the rubber frame from turning outward, and at the same time reducing the process of attaching the edging glue, playing a role in reducing costs and increasing efficiency. In this embodiment, the side wall of the back frame is provided with a protruding plug-in plate positioning groove corresponding to the vertical plug-in plate. Vertical plug-in plates and plug-in plate positioning grooves are provided at the four corners of the back frame, so that the back frame and the rubber frame are firmly positioned. This prevents the rubber frame from turning outward, and at the same time reduces the process of attaching the edging glue, playing a role in reducing costs and increasing efficiency.

[0016] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of the present invention.
