[0002] The backlight glue frame of the backlight is used to protect the backlight components and LCD. The backlight glue frame is made of glue and is easily affected by temperature and expands and contracts due to heat, which can cause looseness or cracks between the LCD and the glue frame. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a backlight glue frame.

[0004] The purpose of this utility model is achieved through the following technical solutions:

[0005] A backlight adhesive frame comprises: a base plate and an annular frame, wherein the annular frame extends from the periphery of the base plate along its thickness direction, the annular frame surrounds the periphery of the base plate to form an installation cavity, and the annular frame is provided with an anti-shrinkage groove along the extension direction.

[0006] In one embodiment, the number of the anti-shrinkage grooves is six.

[0007] In one embodiment, the depth of the anti-shrinkage groove is 0.5 cm.

[0008] In one embodiment, the edge of the bottom plate is aligned with the edge of the annular frame.

[0009] In one of the embodiments, a side of the annular frame close to the installation cavity is provided with an avoidance groove.

[0010] In one embodiment, there are four avoidance grooves, which are respectively arranged around the annular frame.

[0011] In one embodiment, the annular frame is perpendicular to the bottom plate.

[0015] Compared with the prior art, the utility model has at least the following advantages:

[0016] The backlight glue frame of the utility model is provided with a bottom plate and an annular frame connected around the bottom plate, and the bottom plate and the annular frame are both made of rubber. Rubber has a significant effect of thermal expansion and contraction, so an anti-shrinkage groove is opened on the annular frame. When the temperature changes, since there is no glue in the anti-shrinkage groove, the degree of thermal expansion and contraction of the annular frame is reduced, thereby avoiding a large change in the size of the installation cavity in the backlight glue frame, thereby ensuring that the LCD is firmly embedded in the installation cavity.

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a backlight adhesive frame for mounting a backlight and an LCD, and protecting the backlight and the LCD. Figure 1 and Figure 2 , including: a bottom plate 10 and an annular frame 20 connected to the bottom plate 10, and the bottom plate 10 and the annular frame 20 are both made of rubber. Rubber has a significant effect of expansion and contraction when heated and cold, so an anti-shrinkage groove 30 is provided on the annular frame 20. When the temperature changes, since there is no glue in the anti-shrinkage groove 30, the degree of thermal expansion and contraction of the annular frame 20 is reduced, thereby avoiding a large change in the size of the mounting cavity 40 in the backlight glue frame, thereby ensuring that the LCD is firmly embedded in the mounting cavity 40. Specifically, the annular frame 20 extends from the bottom plate 10 along its thickness direction, and the annular frame 20 is surrounded by the bottom plate 10 to form the mounting cavity 40, and the annular frame 20 is provided with an anti-shrinkage groove 30 along the extension direction.

[0024] Among them, the annular frame 20 includes four short boards, which are enclosed on the edges of the four right-angled sides of the bottom plate 10. The top surface of each short board is provided with an anti-shrinkage groove 30, and the bottom surface is connected to the right-angled side of the bottom plate 10. The side edges of the four short boards are connected in sequence to form an annular frame.

[0025] In one embodiment, see Figure 1 The anti-shrinkage grooves 30 are set to six, two anti-shrinkage grooves 30 form a group, and one group of anti-shrinkage grooves 30 is set on three sides of the annular frame 20. And the anti-shrinkage grooves 30 are set to an elliptical structure. Preferably, the depth of the anti-shrinkage grooves 30 is 0.5 cm.

[0026] Furthermore, the annular frame 20 is perpendicular to the bottom plate 10 .

[0027] Furthermore, the edge of the bottom plate 10 is aligned with the edge of the annular frame 20, so that the bottom plate 10 and the annular frame 20 are smoothly connected, and waste of materials is avoided, and sufficient space is provided to install the LCD and backlight, etc. In addition, a side of the annular frame 20 close to the installation cavity 40 is provided with an avoidance groove 50, and the setting of the avoidance groove 50 facilitates the removal of the LCD in the installation cavity 40, improves the removal efficiency, and the shape of the avoidance groove 50 is a quarter of a sphere. Among them, there are four avoidance grooves 50, which are respectively arranged around the annular frame 20, making it more convenient to remove the LCD.

[0028] In another embodiment, the depth of the anti-shrinkage groove 30 is less than the height of the annular frame 20, and the anti-shrinkage groove 30 does not penetrate the annular frame 20. When the backlight plastic frame is subjected to a lateral collision, the annular frame 20 can provide a certain support to protect the LCD in the installation cavity 40. Furthermore, the bottom plate 10 has the same thickness as the annular frame 20, so that the annular frame 20 can provide a certain support for the LCD in the installation cavity 40. In addition, the bottom plate 10 is a rectangular parallelepiped structure, which fits the shape of the LCD, giving users an ultimate viewing experience.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
