[0017] The present invention provides a fixing assembly 100 .

[0018] See also Figures 1 to 3 In one embodiment of the present invention, the fixing assembly 100 is applied to a display device, which includes a display panel 3. The fixing assembly 100 includes: a frame 1 and a frame 2. The frame 1 and the frame 2 are detachably connected, and the frame 2 is used to install and fix the display panel 3.

[0019] In one embodiment, the frame 1 is the foundational component of the entire mounting assembly 100. The frame 1 is primarily used to secure the frame 2 and display panel 3. The frame 1 is typically made of high-strength aluminum alloy or stainless steel. These materials offer high strength, strong wear resistance, lightness, and ease of cleaning, making them convenient for operators. The frame 1 can be a frame structure with four frames 2, or a frame structure with three frames 2, including an upper frame 2 and left and right frames 2. Each frame 2 can be integrally formed by welding, or multiple independent frames 2 can be provided.

[0020] In one embodiment, the core function of the display panel 3 is to protect the display device, while providing a corresponding touch control panel and an interface that allows light to pass through. This panel is usually made of a highly transparent material, such as glass or transparent materials such as polymethyl methacrylate, to ensure that the user can clearly see the image or text on the display screen, while also being able to perform touch-screen control of the display device.

It combines display technology and transparent characteristics to provide users with a novel interactive experience that can transmit visual information without blocking the line of sight, thereby improving space utilization efficiency and design aesthetics.

[0021] In this embodiment, the frame 2 is mainly used to fix the display panel 3. The number of frames 2 is consistent with the number of sides of the frame 1, and there are generally three or four frames. The frame 2 is generally made of high-strength aluminum alloy or plastic material, and is light and durable. One end of the frame 2 is connected to the frame 1 by a detachable connection method such as bolts or snaps, and the other end is connected to the display panel 3 by gluing. Generally, VHB glue can be used, which is an acrylic foam tape with high bonding strength, or a two-liquid mixed hardening glue (AB glue) can be used. The glue has the characteristics of high bonding strength and good sealing, and can effectively protect structures such as display devices. AB glue has high transparency and strong bonding properties, which is conducive to the assembly and use of the display panel 3.

[0022] The technical solution of this utility model provides a frame 1, with a frame 2 detachably connected to the frame 1 via bolts or snaps. The display panel 3 is bonded to the frame 2 using AB glue and VHB glue, further enhancing the flexibility and adaptability of the structure. The detachable frame 2 design allows maintenance personnel to more quickly replace or maintain the display panel 3, reducing the need to disassemble the entire device. The bonding method between the frame 2 and the display panel 3 reduces the risk of damage to the display panel 3 during the disassembly process. This design allows users to quickly replace or repair the display panel 3, helping to maintain the durability and long-term reliability of commercial display TVs.

[0023] In the embodiment of the present utility model, as Figure 1 As shown, the frame 1 is provided with a fixing groove 1 a , and the frame 2 is snap-fitted and located in the fixing groove 1 a .

[0024] In one embodiment of the present invention, a fixing groove 1a is formed in the frame 1 to accommodate and secure the corresponding frame 2. The design of the fixing groove 1a takes into account the size and shape of the frame 2, ensuring that the frame 2 can be accurately snapped into the groove and stably positioned therein. The fixing groove 1a can be formed during the manufacturing process of the frame 1 through methods such as machining, casting, or injection molding. The size and shape of the fixing groove 1a are designed based on the precise dimensions of the frame 2 to ensure that the frame 2 can be smoothly snapped into and retained within the groove. The snap-fit ​​stop design of the frame 2 is designed to ensure that the frame 2 is correctly positioned within the fixing groove 1a, preventing it from shifting during installation or use. During installation, the frame 2 is first aligned with the entrance of the fixing groove 1a and then pushed in manually or mechanically until the snap-fit ​​stop of the frame 2 contacts the retaining structure within the fixing groove 1a, thereby achieving a stable fixation. This design allows for quick installation and removal of the frame 2 while maintaining structural stability and reliability.

[0025] In the embodiment of the present utility model, as Figure 1 As shown, the cross-sectional area of ​​the fixing groove 1 a gradually decreases along the direction facing away from the display panel 3 , and the outer wall of the frame 2 abuts against the inner wall of the fixing groove 1 a .

[0026] In this embodiment, the fixing groove 1a is designed to extend along the direction facing away from the display panel 3, and the cross-sectional area of ​​the fixing groove 1a gradually decreases from one end of the frame 1 close to the display panel to the other end. This design allows the fixing groove 1a to have a larger opening on the side close to the display panel 3, which facilitates the insertion of the frame 2, while gradually narrowing on the side away from the display panel 3 to fit more closely with the frame 2. The outer wall of the frame 2 and the inner wall of the fixing groove 1a are designed to abut against each other, ensuring that the frame 2 is stably positioned in the fixing groove 1a, while allowing the frame 2 to be pushed in or pulled out along the extension direction of the fixing groove 1a when necessary, to achieve a detachable connection with the frame 1. This gradually shrinking design of the fixing groove 1a can be achieved through manufacturing processes such as CNC machining or injection molding. The insertion of the frame 2 can be completed manually, ensuring that the outer wall of the frame 2 fits tightly with the inner wall of the fixing groove 1a, thereby providing the required structural stability and sealing performance.

[0027] In the embodiment of the present utility model, as Figure 1 and Figure 3 As shown, the frame 2 is screwed to the frame body 1 so that the frame 2 and the frame body 1 are connected and fixed.

[0028] In this embodiment, the frame 2 is provided with at least one connection hole. These connection holes are provided to enable a removable connection between the frame 2 and the frame 1. The connection hole can be circular, square, oval, or any other shape suitable for fasteners such as bolts or screws. The connection hole ensures that the frame 2 can be accurately aligned and secured to the frame 1. The connection hole can be formed by methods such as machining, laser cutting, stamping, or injection molding. The size and shape of the connection hole should match the fastener used, leaving a certain clearance to ensure smooth insertion and securement. In addition, the edges of the connection hole can be designed to be smooth or chamfered to reduce wear on the fastener during installation and improve the overall aesthetics of the structure. After the frame 2 is inserted into the fixing slot 1a, the fastener passes through the connection hole and aligns with the corresponding hole in the frame 1. It is then tightened or snapped into place, achieving a stable connection between the frame 2 and the frame 1. This design not only provides a quick and reliable connection method but also facilitates future maintenance and replacement, thereby enhancing the practicality and flexibility of the fixing assembly 100.

[0029] In the embodiment of the present utility model, as Figure 2 As shown, the frame 1 is a three-section structure, and the fixing assembly 100 includes three frames 2 , each of which is detachably connected to one section of the frame 1 .

[0030] In the present invention, the frame 1 adopts a three-section structural design, which makes it easy for users to disassemble the frame 1 to meet different maintenance needs. The fixing assembly 100 includes three independent frames 2, each frame 2 corresponds to a section of the frame 1, and is detachably connected to the section of the frame 1, which can be a bolt connection or a snap connection. In specific implementation, each frame 2 can be designed to have a connection structure that matches the corresponding section of the frame 1, for example, it can be designed with grooves and flanges, or adopt mechanical connection methods such as bolts, nuts, snaps, mortise and tenon structures. These connection structures allow the frame 2 to be quickly installed or disassembled when needed without the need for complicated tools or processes. Through this design, the frame 1 can be disassembled according to actual needs, and the frame 2 of the fixing assembly 100 is easy to install and disassemble, while providing a high degree of adaptability and flexibility.

[0031] In the embodiment of the present utility model, as Figure 1 and Figure 3 As shown, the frame 2 is provided with a first glue groove 2a and a second glue groove 2b. Both the first glue groove 2a and the second glue groove 2b are located on the side of the frame 2 facing the display panel 3. The first glue groove 2a and the second glue groove 2b are used to accommodate different types of adhesives.

[0032] In one embodiment, the frame 2 is designed to include a first glue groove 2a and a second glue groove 2b, and the first glue groove 2a and the second glue groove 2b are respectively used for bonding and fixing two types of glue, VHB glue and AB glue, to the display panel 3. Both glue grooves are located on the inner side of the frame 2, that is, the side facing the display panel 3, to ensure that the adhesive can form a uniform and continuous bonding layer between the frame 2 and the display panel 3. The glue grooves are evenly distributed along the length direction of the frame 2. The design of the glue grooves should take into account the fluidity of the adhesive and the bonding strength after curing to ensure that the adhesive can be fully filled in the glue grooves and is not easy to overflow. VHB glue has the characteristics of high bonding strength and good sealing, and can effectively protect structures such as display devices; AB glue has high transparency and strong bonding performance, and can quickly solidify, which is conducive to rapid assembly. By using two different glues at the same time, the effect of rapid solidification and high connection strength is achieved.

[0033] In the embodiment of the present utility model, as Figure 1 and Figure 3 As shown, the first glue groove 2a is located at one end of the frame 2 close to the outer wall of the frame body 1, and the width of the first glue groove 2a is wider than the second glue groove 2b.

[0034] In one embodiment, the first and second adhesive grooves 2a and 2b of the fixed frame 2 have different widths, with the first adhesive groove 2a being wider than the second adhesive groove 2b to accommodate different types of adhesives. The first adhesive groove 2a is specifically positioned at the end of the frame 2 near the outer wall of the frame 1. This placement allows the first adhesive groove 2a to be closer to the area where the fixing assembly 100 connects to the frame 1, facilitating structural stability. The first adhesive groove 2a is designed to accommodate the width of Very High Bond (VHB) tape, which is known for its fast bonding properties. VHB tape typically has a wider bonding surface, providing stronger adhesion and sealing performance. Therefore, the width of the first adhesive groove 2a must be designed to accommodate the specifications of the VHB tape to ensure that the tape fits completely within the groove. The second adhesive groove 2b is designed to accommodate AB glue, a two-component adhesive typically composed of two chemical substances that undergo a chemical reaction and cure upon mixing. The dimensions of the second adhesive groove 2b are determined based on the viscosity of the AB glue and the desired bonding thickness to ensure that the AB glue evenly fills the groove and achieves a good bond. In this bonding method, the width of the VHB glue is only 6mm, and the width of the AB glue is 2mm. In the TV, the distance between the display area and the outermost edge is only 21mm, achieving a narrow edge of the display area and a borderless appearance of the glass screen2.

[0035] In the embodiment of the present utility model, as Figure 1 and Figure 3 As shown, an anti-overflow groove 2c is provided on the bottom wall of the second glue groove 2b.

[0036] In this embodiment, to ensure the stability of the AB glue in the second glue groove 2b and prevent it from overflowing during the curing process, the bottom wall of the second glue groove 2b is specially designed with an anti-overflow groove 2c. The anti-overflow groove 2c is a series of small grooves or grooves opened along the inner edge of the bottom wall of the glue groove. Its function is to provide an additional holding space when the adhesive fills the glue groove to absorb excess adhesive, thereby preventing the adhesive from overflowing the glue groove boundary during the curing process. The anti-overflow groove 2c can be designed as a continuous groove or small grooves distributed at intervals to adapt to the flow characteristics of different adhesives. The size of the anti-overflow groove 2c, including its depth and width, should be determined according to the size of the glue groove and the viscosity of the adhesive used to ensure that the anti-overflow groove 2c can effectively control the flow of the adhesive and prevent overflow.

[0037] In the embodiment of the present utility model, as Figure 1 As shown, the first glue groove 2a and the second glue groove 2b are both formed by the raised portion of the frame 2 .

[0038] In an embodiment of the present utility model, a raised structure is formed on the material of the frame 2 to enclose and form the first glue groove 2a and the second glue groove 2b, thereby achieving precise accommodation of the adhesive while cleverly maintaining the overall thickness and structural integrity of the frame 2. This design utilizes the characteristics of the material of the frame 2 itself, and forms the required raised portion through processes such as mold pressing, bending or CNC processing, ensuring that the first glue groove 2a is adapted to VHB tape and the second glue groove 2b is adapted to AB glue. During the bonding process, the inner edge of the raised portion forms the bottom of the glue groove, and the original surface of the frame 2 forms the side of the glue groove. No additional material or thinning of the frame 2 is required, thereby ensuring the strength and stability of the frame 2. By accurately filling the adhesive and pressing the display panel 3, an efficient and stable bonding effect is achieved, while simplifying the manufacturing process, improving production efficiency, and enhancing the durability and reliability of the display device.

[0039] The present invention also provides a display device comprising a fixing assembly 100, a backlight assembly, and a display panel 3. The specific structure of the fixing assembly 100 is similar to that of the aforementioned embodiments. Since the present display device utilizes all the technical solutions of all the aforementioned embodiments, it at least possesses all the beneficial effects of the technical solutions of the aforementioned embodiments, and therefore will not be further detailed here. The backlight assembly and the fixing assembly 100 are detachably connected, and the display panel 3 is bonded to the frame 2.

[0040] In one embodiment, the fixing assembly 100 provides a stable and reliable support base for the display device. The fixing assembly 100 is connected to the backlight assembly via a detachable connection, typically using a quick-release snap, bolt connection, or locking mechanism. This allows the backlight assembly to be easily removed and reinstalled when maintenance or replacement is required, without having to replace the entire display device. The backlight assembly is responsible for providing a uniform background light source for the display panel 3 to ensure image brightness and clarity. The detachable design of the backlight assembly not only facilitates maintenance and upgrades, but also allows for the flexible selection of different backlight technologies, such as LED backlight, EL backlight, or other backlight solutions, based on different application requirements. The display panel 3, which serves as the image display portion of the display device, is fixed to the frame 2 by bonding. This bonding typically uses a highly transparent adhesive, such as VHB tape or other types of optical adhesive, to ensure a secure bond between the display panel 3 and the frame 2 without interfering with the display effect. This design allows the display panel 3 to be quickly removed from the display device, facilitating maintenance and servicing by staff.
