[0002] With the continuous advancement of modern technology, the application scope of display components is becoming increasingly wide, covering many fields such as computers, mobile phones, in-vehicle equipment, ultrasonic instruments, and patient monitors.

[0003] Currently, the industry typically employs the following common methods when connecting and fixing display components to products. One method involves applying double-sided tape, quick-drying adhesive, or hot melt adhesive around the glass of the display component, directly adhering the component to the housing. This method is relatively simple and can achieve a certain degree of connection between the display component and the housing.

[0004] However, existing connection and fixing methods have significant shortcomings. Using adhesive bonding not only makes repairs difficult, potentially requiring the replacement of both the display component and the housing, but also carries the risk of the display component detaching if the adhesive fails. Adhesive bonding also makes disassembling the display component difficult, increasing repair costs, and can lead to problems such as adhesive failure, overflow, and whitening, while also limiting the design of the housing structure.

[0005] In conclusion, how to prevent the screen from detaching when the adhesive fails is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

This application discloses a display component connection and fixing structure.

[0044] The core of this utility model is to provide a display component connection and fixing structure.

[0045] Please refer to Figure 1 and Figure 2 .

[0046] The display component connection and fixing structure provided by this utility model includes a fixing frame 2 and a housing 4. Multiple fixing frames 2 are arranged around the back plate of the display component 1. The multiple fixing frames 2 are glued to the back plate of the display component 1. A first limiting structure is provided between the fixing frame 2 and the side of the display component 1 so that the fixing frame 2 is positioned on the side of the display component 1. The display component 1 is embedded in the housing 4. A second limiting structure is provided between the housing 4 and the fixing frame 2 so that the fixing frame 2 is positioned in the housing 4.

[0047] Specifically, an installation space is formed inside the housing 4, and the display component 1 is embedded in the installation space. Multiple fixing brackets 2 are provided at the connection between the inner wall of the housing 4 and the display component. The fixing brackets 2 can be arranged in a circumferential manner. One side of the fixing bracket 2 is bonded to the back plate of the display component 1, and the other side of the fixing bracket 2 is fixed to the side of the display component 1 perpendicular to the plane of the display component 1 by a first limiting structure. The other side of the fixing bracket 2 is fixed to the surface of the housing 4 by a second limiting structure. Thus, the display component 1 and the housing 4 are indirectly fixed by means of the fixing brackets 2, the first limiting structure and the second limiting structure. The first limiting structure and the second limiting structure form an interlocking structure.

[0048] The aforementioned display component connection and fixing structure includes a first limiting structure and a second limiting structure. The interlocking structure formed between the two can effectively fix the housing 4, the fixing frame 2 and the display component 1, thereby effectively preventing the display component 1 from falling off when the adhesive fails.

[0049] The display component connection and fixing structure provided by this utility model will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0050] In one specific implementation, reference is made to... Figure 3 and Figure 4 The first limiting structure includes a first limiting hole 202, a limiting frame 102, and a limiting pin 3. The first limiting hole 202 is formed on the fixing frame 2. The limiting frame 102 is disposed on the back plate of the display component 1 and extends to the side away from the back plate. The limiting frame 102 is provided with a second limiting hole corresponding to the first limiting hole 202. The limiting pin 3 is threadedly connected to the first limiting hole 202 and the second limiting hole to restrict the movement of the display component 1 in the first direction.

[0051] Specifically, the fixing frame 2 has an irregular shape and its main body is a frame structure. The first limiting hole 202 is located on the side of the fixing frame 2 near the display component 1, where the side of the display component 1 is the limiting frame 102. The glass screen 101 is mounted on the limiting frame 102, and the two together constitute the main structure of the display component 1. The second limiting hole is coaxially arranged with the first limiting hole 202, but the second limiting hole is opened on the limiting frame 102. The limiting pin 3 passes through the first limiting hole 202 and the second limiting hole in sequence to fix the fixing frame 2 and the display component 1. The fixing pin 3 can be fixed with the first limiting hole 202 and the second limiting hole by means of threaded engagement or interference fit. The limiting pin 3 can be completely located inside the housing 4, so that the housing 4 does not need to be processed. Under the action of the limiting pin 3, if the fixing frame 2 and the display component 1 become detached, the limiting pin 3 can effectively prevent the display component 1 from delaminating in the first direction (specific direction as shown in the figure). Figure 3 (As shown, and will not be explained further) This movement prevents the display component 1 from detaching if the adhesive fails. Furthermore, the mounting bracket 2 is not subject to the assembly force of the retaining pin 3, reducing the assembly stress on the display component 1, decreasing the stress on the adhesive, and lowering the risk of adhesive failure.

[0052] It should be noted that the limiting pin 3 can be a metal wire, screw, threaded pin, unthreaded pin, optical shaft, etc. When a screw is selected, its head shape can be cross-shaped, slotted, etc., to facilitate installation and disassembly using tools.

[0053] Furthermore, an installation channel is formed on the fixing frame 2 at the first limiting hole 202, and a first abutting plate and a second abutting plate are respectively provided on both sides of the installation channel, and the first abutting plate and the second abutting plate abut against the outer periphery of the limiting nail 3 respectively.

[0054] Specifically, the installation channel is a semi-through channel used to accommodate the limiting pin 3, and its shape can be circular or square. A first abutment plate and a second abutment plate (i.e., the abutment plates on the upper and lower sides of the limiting pin 3 in the figure) are respectively located on both sides of the installation channel. The first and second abutment plates are flat structures made of the same material as the fixing frame 2. They abut against the outer periphery of the limiting pin, further restricting the movement of the limiting pin 3 and guiding it during insertion.

[0055] Optionally, two first limiting holes 202 are provided on the same fixing frame 2, and they are arranged opposite to each other on both sides of the fixing frame 2.

[0056] Specifically, there are two first limiting holes 202 on the same fixed frame 2, which are arranged opposite to each other on both sides of the fixed frame 2. This can more stably restrict the movement of the display component 1 and further improve the stability of the device.

[0057] Based on any of the above embodiments, refer to Figure 4 The housing 4 is provided with a limiting inner frame 403 that cooperates with the limiting frame 102 to restrict the movement of the display component 1 in a third direction.

[0058] Specifically, the inner limiting frame 403 is disposed within the housing 4 and cooperates with the limiting frame 102. Its structure is a concave frame structure used to limit the movement of the display component 1 in the third direction. The inner limiting frame 403 and the limiting frame 102 clamp the fixing bracket 2 between them, thereby effectively limiting the movement of the limiting component 1 in the third direction.

[0059] Based on any of the above embodiments, refer to Figure 2 The second limiting structure includes a threaded hole, a through hole, and a fixing screw 5. The threaded hole is opened on the fixing bracket 2; the through hole is opened on the housing 4, and the through hole and the threaded hole are matched; the fixing screw 5 passes through the through hole and is threadedly connected to the threaded hole, so that the fixing bracket 2 is fixed in the housing 4.

[0060] Specifically, the threaded hole and the through hole are correspondingly set, and the fixing screw 2 passes through the through hole and the threaded hole in sequence, and is threadedly connected to the threaded hole, thereby fixing the housing 4 and the fixing frame 2, and indirectly fixing the housing 4 and the display component 1. When the display component 1 and the fixing frame 2 are debonded, since there is a first limiting structure between the fixing frame 2 and the display component 1, it works in conjunction with the second limiting structure to realize the interlocking structure between the fixing frame 2 and the display component 1, thereby preventing the display component 1 from falling off after debonding.

[0061] Optionally, a total of six sets of second limiting structures are provided, which are respectively provided on three adjacent sides of the housing 4, and two sets of second limiting structures are provided on each side.

[0062] Specifically, to further improve the stability between the housing 4 and the display component 1, a total of six fixing brackets 2 are provided, and a total of six sets of corresponding second limiting structures are also provided, thereby effectively achieving stable fixing between the housing 4 and the display component 1.

[0063] Furthermore, a recessed hole is formed in the housing 4 at the fixing screw 5, and the end of the fixing screw 5 is embedded in the recessed hole so that the surface end of the fixing screw 5 is lower than the surface of the housing 4.

[0064] Specifically, the housing 4 has a recessed hole at the fixing screw 5. The recessed hole is a concave hole in which the end of the fixing screw 5 is embedded, so that the surface end of the fixing screw 5 is lower than the surface of the housing 4. This can prevent the fixing screw 5 from protruding and affecting the overall aesthetics and use.

[0065] Based on any of the above embodiments, refer to Figure 2 A limiting slot 201 is formed on the side of the fixing frame 2 near the inner wall of the housing 4, and a limiting block 401 is provided inside the housing 4 to engage with the limiting slot 201.

[0066] Specifically, the limiting slot 201 is located on the side of the fixing frame 2 near the inner wall of the housing 4. It is a recessed groove, which can be rectangular, trapezoidal, or similar in shape, and is generally made of plastic or metal, such as aluminum alloy, providing a certain degree of strength and wear resistance. The function of the limiting slot 201 is to engage with the limiting block 404 inside the housing 4. An alternative structure could be a protruding buckle that engages with the slot inside the housing 4.

[0067] Based on any of the above embodiments, refer to Figure 3 The housing 4 is provided with a frame 402 around its perimeter, the display component 1 is embedded in the frame 402, and the surface of the display component 1 is lower than the surface of the frame 402.

[0068] Specifically, the frame 402 is disposed around the perimeter of the housing 4, the display component 1 is embedded in the frame 402, and the surface of the display component 1 is lower than the surface of the frame 402. The frame 402 can protect the display component. While restricting the movement of the display component 1 in the first direction, the glass screen 101 of the display component 1 is lower than or flush with the frame 402 of the housing 4. The frame 402 restricts the movement of the display component 1 in the second and third directions.

[0069] Based on any of the above embodiments, please refer to Figure 5 A buffer ring 404 is formed inside the housing 4, and the buffer ring 404 abuts against the bottom of the display component 1; a buffer pad 406 is formed circumferentially inside the housing 4, and the buffer pad 406 abuts against the side wall of the display component.

[0070] Specifically, the buffer ring 404 is formed inside the housing 4 and abuts against the bottom of the display component 1. Its material can be a soft material such as rubber, and it has the function of buffering and shock absorption. The buffer pad 406 is formed circumferentially inside the housing 4 and abuts against the side wall of the display component 1, which also plays a buffering role.

[0071] When the display assembly 1 is assembled with the buffer ring 404 around the housing 4, the bottom surface of the glass screen 101 of the display assembly 1 compresses the buffer ring 404, which serves as a seal. Buffer pads 406 are located on the four sides of the glass screen 101. The included angle 405 of the buffer ring 404 is less than 90°, which reduces the compressive force exerted on the glass screen 101 by the buffer ring 404. Thus, the buffer ring 404 and buffer pads 406 provide cushioning in three directions when the glass screen 101 is dropped or during use. This also enhances sealing, reduces assembly stress, and improves the reliability of the display assembly 1.

[0072] In this embodiment, it should be noted that when the adhesive fails, the housing 4 prevents the fixing frame 2 from moving in the first direction through the fixing screws 5 and the limiting block 401 of the housing 4 and the limiting slot 201 of the fixing frame 2. The first limiting hole 202 of the fixing frame 2 restricts the movement of the display component 1 in the first direction through the limiting pin 3. When the movement of the display component 1 in the first direction is restricted, the glass screen 101 of the display component 1 is lower than or flush with the frame 402 around the housing 4, and the frame 402 restricts the movement of the display component 1 in the second and third directions. The display component 1 can also be restricted to move in the second direction through the limiting pin 3 and the first limiting hole 202 of the fixing frame 2. The display component 1 can also be restricted to move in the third direction through the limiting inner frame 403 of the housing 4 and the limiting frame 102 of the display component 1. This can prevent the display component 1 from falling off when the adhesive fails.

[0073] The implementation principle of the display component connection and fixing structure in this application embodiment is as follows: the fixing frame 2 is glued to the back plate of the display component 1, and then the first limiting structure and the second limiting structure are used for positioning and fixing, thus realizing a stable connection between the display component 1 and the housing 4. This connection method not only facilitates disassembly and maintenance, but also prevents the display component from falling off when the glue fails through the limiting structure. At the same time, the fixing frame 2 has a small structural size and can be adapted to display components of various specifications, reducing the types and costs of fixing frames 2. The setting of the buffer ring 404 and the buffer pad 406 can reduce assembly stress and provide cushioning when the screen is dropped, improving the reliability of the display component. Compared with the prior art, it has significant improvements in connection stability, maintainability, adaptability and cost.

[0074] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0075] The above provides a detailed description of a display component connection and fixing structure provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
