[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0028] In order to solve the problem that in the prior art, after the middle frame 1 structure is assembled during product transportation, the fixation between the film 3 and the middle frame 1 is not stable enough, resulting in easy friction between the surface of the film 3 and adjacent components, which causes the film 3 to be scratched or worn, the present utility model discloses a display film fixing structure. Refer to Figures 1 to 5, the display diaphragm fixing structure includes: a middle frame 1, a diaphragm 3, and a fixing member 2. The middle frame 1 is provided with a first through hole 14. The middle frame 1 is further provided with a film placement groove 16 for accommodating the edge of the diaphragm 3. The first through hole 14 communicates with the film placement groove 16. The edge of the diaphragm 3 is provided with a second through hole 31. The fixing member 2 sequentially passes through the first through hole 14 and the second through hole 31. In display products, especially in ultra-thin display products with large screen sizes, due to the installation method of inserting the diaphragm 3 between the middle frame 1 in the prior art, this unstable connection method causes the diaphragm 3 to have a relatively large relative movement with the components on the front panel of the display, especially the protective glass, during product transportation, and it will be scratched or worn during mutual friction, resulting in product defects and ultimately affecting the user experience. Therefore, the display diaphragm fixing structure proposed by the present utility model is needed to solve this problem. By providing a specially designed film placement groove 16 on the inner side surface 12 of the middle frame 1, it can accommodate the edge of the diaphragm 3, ensuring that the diaphragm 3 is limited within the film placement groove 16 at each of its edges, and guaranteeing that the diaphragm 3 has a fixed relative position during use. The middle frame 1 is provided with a first through hole 14. Through the first through hole 14, the fixing member 2 can pass through the middle frame 1 and then through the second through hole 31 provided on the diaphragm 3 to provide the necessary fixing force and support. The fixing member 2 realizes serial fixation by passing through the first through hole 14 and the second through hole 31, enhancing the structural stability between the diaphragm 3 and the middle frame 1, improving the fixing effect of the diaphragm 3, and enhancing the transportation safety.

[0029] Compared with the prior art, in the display diaphragm fixing structure of the present utility model, by providing a first through hole 14 on the middle frame 1 and a second through hole 31 on the edge of the diaphragm 3, and using the fixing member 2 to sequentially pass through the first through hole 14 and the second through hole 31, a relatively stable structural relationship is formed between the diaphragm 3 and the middle frame 1, thereby restricting the sliding of the diaphragm 3 and making it less likely for the surface of the diaphragm 3 to rub against adjacent components, thus alleviating the problem of the diaphragm 3 being scratched or worn.

[0030] In one embodiment, referring to Figure 1 and Figure 2 , the middle frame 1 further includes a fixing hole 15. The fixing hole 15 communicates with the film placement groove 16 and is arranged opposite to the first through hole 14 on both sides of the film placement groove 16. The fixing member 2 is inserted into the fixing hole 15. In order to enable the fixing member 2 to be stably fixed to the middle frame 1, the fixing hole 15 is provided. To achieve the preset function of the fixing hole 15, the fixing hole 15 needs to communicate with the film placement groove 16 and be arranged opposite to the first through hole 14 on both sides of the film placement groove 16, so that the fixing member 2 not only passes through the first through hole 14 and the second through hole 31 of the diaphragm 3, but also is inserted into the fixing hole 15 of the middle frame 1. The fixing hole 15 is symmetrically arranged with the first through hole 14, increasing the support points of the fixing member 2, further strengthening the fixing effect of the diaphragm 3 and also further improving the overall structural stability of the insertion of the fixing member 2.

[0031] Further, the fixing hole 15 and the fixing member 2 are in interference fit. Refer to Figure 1 and Figure 2 . The interference fit between the fixing member 2 and the fixing block can ensure the stable connection between the diaphragm 3 and the display housing, preventing loosening or falling off. At the same time, this fixing method can also increase the structural stability of the entire display device. In particular, the size of the fixing hole 15 farther away from the film placement groove 16 is smaller, and such a design can make the fixing member 2 more stable when installed under a certain insertion force and not easily loosen. On this basis, the shape and material of the fixing member 2 can be reasonably selected so that the fixing member 2 can be easily disassembled when maintenance is required, facilitating the maintenance and replacement of the diaphragm 3.

[0032] In one embodiment, refer to Figure 1 and Figure 2 . A limiting groove 17 is provided at one end of the first through hole 14 away from the film placement groove 16, and a stop protrusion 22 is provided on the fixing member 2, and the stop protrusion 22 is arranged in the limiting groove 17. On the middle frame 1, a limiting groove 17 is provided at one end of the first through hole 14 away from the film placement groove 16. The function of the limiting groove 17 is to limit the depth of the downward insertion of the fixing member 2, preventing the fixing member 2 from being over-inserted during installation and being difficult to pull out during subsequent maintenance, thereby ensuring the convenience of the fixing member 2 during installation and disassembly, so that the user can operate more easily when maintaining or replacing the diaphragm 3. The fixing member 2 is provided with a stop protrusion 22, and the stop protrusion 22 can be arranged in cooperation with the limiting groove 17. When the fixing member 2 is inserted into the fixing hole 15, the stop protrusion 22 can be embedded in the limiting groove 17, thereby forming a mechanical lock and further enhancing the connection stability between the fixing member 2 and the middle frame 1. This embodiment not only improves the safety and stability of the fixing of the diaphragm 3, but also optimizes the durability of the overall structure.

[0033] In one embodiment, refer to Figure 1 、 Figure 2 and Figure 4, the limiting grooves 17 are provided with convenient-taking grooves 18 on both sides along the length direction of the film-placement groove 16. In the actual use process, it is found that it is not easy for tools to intervene when disassembling and assembling the fixing member 2. If a tool is forcibly inserted around the stop protrusion 22 for disassembly and assembly, the frame body is easily damaged, and seriously, abnormal protrusions may even appear on the visible surface 11, resulting in the inability to reinstall the front panel of the display. Therefore, the convenient-taking grooves 18 are provided. The limiting grooves 17 are provided with convenient-taking grooves 18 on both sides along the length direction of the film-placement groove 16. These convenient-taking grooves 18 enable tools to be used more conveniently or manual operations to be carried out when installing or disassembling the fixing member 2, facilitating maintenance and assembly production. Further, the existence of the convenient-taking grooves 18 also enables maintenance personnel to access the fixing member 2 more easily. Especially when disassembly or adjustment is required, the fixing member 2 can be quickly located and operated, reducing the complexity of the operation. In the automated production process, the convenient-taking grooves 18 also provide space for the manipulator clamp to pick up the fixing member 2 for insertion operations, enabling the manipulator clamp to grasp the fixing member 2 more stably, and thus carrying out placement, improving the assembly speed and reducing the failure probability.

[0034] Further, referring to Figure 1 and Figure 4 , the convenient-taking groove 18 is provided with a convenient-taking inclined surface 181, and the convenient-taking inclined surface 181 is arranged away from the limiting groove 17. The convenient-taking groove 18 is provided with a convenient-taking inclined surface 181, and this inclined surface is arranged away from the limiting groove 17. This design enables users to easily slide the tool into the convenient-taking groove 18 by using the inclination angle of the inclined surface when operating the fixing member 2, enhancing the convenience of disassembly. The existence of the convenient-taking inclined surface 181 makes the picking and placing of the fixing member 2 smoother, and users can complete the operation without excessive force, thereby reducing the risk of damage caused by improper operation.

[0035] In an embodiment, referring to Figure 1 、 Figure 2 and Figure 3, the fixing member 2 is further provided with a first plate member 21 that sequentially passes through the first through hole 14 and the second through hole 31 and is fixed to the fixing hole 15. The stop bump 22 includes a second plate member 23 and a third plate member 24. The second plate member 23 is connected to the first plate member 21 and is bent at a right angle along the connection, and the third plate member 24 is connected to the second plate member 23 and is bent in the opposite direction along the connection. For the convenience of production, the fixing member 2 is designed as a sheet metal part. The fixing member 2 includes a first plate member 21 that sequentially passes through the first through hole 14 and the second through hole 31 and is fixed in the fixing hole 15, ensuring the tight combination of the fixing member 2 and the diaphragm 3 and enhancing the stability of the overall structure. The stop bump 22 on the fixing member 2 includes a second plate member 23 and a third plate member 24. The second plate member 23 is connected to the first plate member 21 and is bent at a right angle along the connection, and the third plate member 24 is connected to the second plate member 23 and is bent in the opposite direction along the connection. This design of reverse bending can further enhance the supporting force of the fixing member 2, making the fixing member 2 not easily deformed. The structural design of this embodiment makes it more convenient to install and disassemble the fixing member 2. The user can complete the replacement of the diaphragm 3 through simple operations without sacrificing the fixing strength and safety.

[0036] Further, referring to Figure 1 , Figure 2 and Figure 3 , a gap area 25 is provided between the second plate member 23 and the third plate member 24. The gap area 25 is used for inserting a tool for disassembling the fixing member 2. During actual assembly and disassembly, the design of the gap area 25 provides a convenient space for inserting a tool to assemble and disassemble the fixing member 2. The design of the gap area 25 reduces the operation difficulty during assembly and maintenance and improves work efficiency. During assembly and maintenance, the fixing member 2 can be quickly and conveniently disassembled and replaced. In some cases, by providing the gap area 25 between the second plate member 23 and the third plate member 24, it can also avoid direct damage to the middle frame 1 and other structures when using the tool, thus ensuring the product quality.

[0037] In an embodiment, an outer layer is further wrapped on the fixing member 2. The outer layer is close to the second through hole, and the outer layer is made of an elastic material. In actual use, it is found that when the hole wall of the second through hole 31 comes into contact with the fixing member 2, during the transportation and use of the display, the micro-collisions caused by vibration or relative movement may damage the diaphragm 3. Allowing this situation to exist for a long time may cause the diaphragm 3 to crack and appear cracks, resulting in quality problems of the display. It may also cause micro-debris to be generated on the diaphragm 3 due to micro-collisions, affecting the display effect of the display or being inhaled by people and damaging the human body. To solve this technical problem, the fixing member 2 is subjected to a rubber coating treatment, and after the rubber coating treatment, an outer layer is formed on the outer surface of the fixing member 2. The material of the outer layer is an elastic material, which can play a buffering role to a certain extent, so that the micro-collisions between the diaphragm 3 and the fixing member 2 are reduced due to the existence of the elastic outer layer, thereby reducing the risk of the diaphragm 3 cracking or generating micro-debris due to micro-collisions. Further, by subjecting the fixing member 2 to a rubber coating treatment to wrap the outer layer thereon, when the fixing member 2 is a sheet metal part, the outer layer can also prevent the fixing member 2 from rusting and extend the service life of the fixing member 2.

[0038] In an embodiment, the first through hole 14 is arranged close to the front panel of the display, and the fixing hole 15 is arranged close to the back housing of the display. The first through hole 14 is arranged on the visible surface 11, and the fixing hole 15 is arranged on the back surface 13. In the actual production process, since the front panel is usually a glass panel, which is usually one of the last assembled components of the display, in order to facilitate the operation of manual or mechanical means, the visible surface 11 is always arranged upward during the assembly of the display. Therefore, arranging the first through hole 14 on the visible surface 11 simplifies the assembly process during the assembly of the display, improving the assembly efficiency and accuracy. Further, according to the layout of the fixing hole 15 and the first through hole 14 set in this embodiment, the display diaphragm fixing structure is also more visually tidy, avoiding excessive exposed structures and enhancing the overall aesthetics.

[0039] The present utility model also provides a display device, including the above-mentioned display diaphragm fixing structure. The design of this display device fully integrates the display diaphragm fixing structure, ensuring a firm connection between the diaphragm 3 and the middle frame 1, preventing the diaphragm 3 from rubbing against adjacent components, especially the front panel, and improving the display effect and durability.

[0040] The above are only the specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claims.
