[0017] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0018] Please refer to the attached Figure 1 The embodiment of the present application provides a rubber frame structure, including a rubber frame body 100, the rubber frame body 100 is formed with a mounting cavity, the inner wall of the rubber frame body 100 is provided with a rectangular card slot 130, the card slot 130 extends to the top surface of the rubber frame body 100 to form an opening portion 133, the card slot 130 includes a first groove wall surface 131 arranged away from the mounting cavity and two second groove wall surfaces 132 adjacent to the first groove wall surface 131, wherein an end of at least one second groove wall surface 132 close to the opening portion 133 is inclined toward the direction of the other second groove wall surface 132.

[0019] In this embodiment, the frame structure includes a frame body 110 and a circumferential side wall portion 120, wherein the circumferential side wall portion 120 is disposed on the frame body 110 and surrounds the frame body 110. The frame body 110 and the circumferential side wall portion 120 together form an installation cavity for installing components such as a light guide plate, a diffuser, and a light assembly.

[0020] The circumferential side wall portion 120 is provided with a rectangular card slot 130, and the card slot 130 extends to the top surface of the plastic frame body 100 to form an opening portion 133. The card slot 130 includes a first slot wall surface 131 arranged away from the installation cavity and two second slot wall surfaces 132 adjacent to the first slot wall surface 131. At least one end of the second slot wall surface 132 close to the opening portion 133 is inclined toward the direction of the other second slot wall surface 132. Such an arrangement can expand the width of the card slot 130 entrance, so that the protruding structure of the light guide plate can be easily and conveniently inserted into the card slot 130, thereby improving the work efficiency of assembling the light guide plate to the plastic frame structure.

[0021] Please refer to the attached Figure 2 In some embodiments of the present application, the ends of the two second groove walls 132 close to the opening 133 are inclined toward each other. Such an arrangement can further expand the width of the entrance of the card slot 130, so that the protruding structure of the light guide plate can be more easily and conveniently inserted into the card slot 130. At the same time, while further expanding the width of the entrance of the card slot 130, it can also prevent the inclined angle of the inclined end 1321 of any second groove wall 132 from being too large.

[0022] The inclined angle of the inclined end 1321 of the second groove wall surface 132 may be 5-15°, which is not limited in the present application.

[0023] In some embodiments of the present application, the frame body 100 includes a frame body 110 and a circumferential side wall portion 120 arranged around the frame body 110, and the card slot 130 is arranged in the circumferential side wall portion 120, wherein the distance between the inclined end of the two groove wall surfaces and the frame body 110 is different.

[0024] In this embodiment, the distance between the inclined end of the two groove walls and the frame body 110 is different, that is, there is a height difference between the inclined ends 1321 of the two second groove walls 132. This arrangement allows the part of the second groove wall 132 corresponding to the above-mentioned height difference to guide the insertion of the protruding structure, further improving the ease with which the protruding structure of the light guide plate is inserted into the slot 130.

[0025] The inclined angles of the inclined ends 1321 of the two second groove walls 132 are the same or different. Preferably, the inclined angles of the inclined ends 1321 of the two second groove walls 132 are different, which can reduce the difficulty of processing the slot 130 .

[0026] Of course, in other embodiments, the heights of the inclined ends 1321 of the two second groove walls 132 may be the same.

[0027] Please refer to the attached Figure 3In some embodiments of the present application, the glue frame body 100 includes a circumferential side wall portion 120 arranged around the installation cavity, the card slot 130 is arranged on the circumferential side wall portion 120, and the first groove wall surface 131 is provided with a glue injection hole 140, and the glue injection hole 140 extends from one end away from the installation cavity to the outer wall surface of the circumferential side wall portion 120.

[0028] In this embodiment, by providing the above-mentioned glue injection hole 140 , glue can be injected into the card slot 130 through the glue injection hole 140 to fill the gap between the protruding structure and the card slot 130 and make the two bonded together.

[0029] It should be understood that the glue injected into the glue injection hole 140 may be a washable glue to facilitate the subsequent disassembly of the light guide plate.

[0030] In some embodiments of the present application, the glue injection hole 140 is curved. Such a configuration can increase the bonding area between the glue and the glue frame, and can also reduce the light transmitted from the light guide plate through the glue injection hole 140 .

[0031] Of course, in order to avoid the problem of light transmission through the glue injection hole 140 , a light-shielding tape may be adhered to one end of the glue injection hole 140 located on the outer wall surface of the circumferential side wall portion 120 .

[0032] In some embodiments of the present application, the first groove wall 131 and the two groove walls are provided with a glue introduction groove 150, wherein the glue introduction groove 150 located on the first groove wall 131 is respectively connected with the glue introduction groove 150 located on the two groove walls, and the glue introduction groove 150 located on the first groove wall 131 is connected with the glue injection hole 140. Such a configuration can enable the glue injected through the glue injection hole 140 to be better filled into the first groove wall 131 and the assembly gap between the two groove walls and the protruding structure.

[0033] The embodiment of the present application further provides a liquid crystal module, comprising the plastic frame structure in the above embodiment.
