Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device screen technology, specifically to a shockproof adjustable screen assembly. Background Technology
[0002] In the field of electronic devices, the screen assembly, as a core component, directly affects the display effect, user experience, and reliability of the device. Currently, most traditional screen assemblies adopt a fixed assembly method, that is, the inner display screen and the outer touch screen are directly fixed to the frame using adhesives, clips, or screws. This assembly method has obvious shortcomings: on the one hand, due to tolerances in the manufacturing and assembly process, it is difficult to achieve precise alignment between the screen and the frame, which can easily lead to problems such as screen display area misalignment and uneven bezel width, seriously affecting the product appearance and user experience; on the other hand, when the device is subjected to external impacts (such as drops or squeezing), the rigidly connected screen assembly lacks an effective cushioning mechanism, and the inner display screen and the outer touch screen are easily damaged due to stress concentration, resulting in a shortened product lifespan. In addition, when assembly errors occur, it is difficult to adjust the position of the fixedly assembled screen assembly, often requiring the entire screen assembly to be disassembled and reinstalled, which is not only difficult to repair but also costly.
[0003] As electronic devices become thinner, lighter, and more reliable, the market demands higher precision in screen assembly and improved shock absorption. Therefore, there is an urgent need for a screen assembly structure that can achieve precise screen positioning while also providing good shock resistance, in order to address the problems existing in current technologies.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1-2 In this embodiment of the utility model, a shockproof adjustable screen assembly is applicable to various electronic display devices such as mobile phones, tablets, and vehicle central control screens.
[0027] The shockproof adjustable screen assembly mainly includes an inner display screen 1, an outer touch screen 2, a frame 3, and a ribbon cable 4. The inner display screen 1 is composed of a substrate layer, a display function layer, and a polarizer layer stacked sequentially, used to display image information; the outer touch screen 2 covers the inner display screen 1 and is connected by an optical adhesive layer to realize touch operation sensing and to fix the outer touch screen 2 and the inner display screen 1, thereby facilitating the installation of the outer touch screen 2 and the inner display screen 1 in the frame 3; the frame 3 is made of plastic or metal and is used to support and fix the inner display screen 1 and the outer touch screen 2; the ribbon cable 4 connects the inner display screen 1, the outer touch screen 2, and an external control module (such as a PCB motherboard) to transmit image signals, touch signals, and power.
[0028] The core of this utility model lies in the adjustable snap-fit structure and elastic filling layer 5 provided between the frame 3 and the inner display screen 1 and the outer touch screen 2. The adjustable snap-fit structure includes a groove 6 opened along the inner wall of the frame 3, and a slider 7 extending from the edge of the substrate layer (such as a glass substrate, thus giving the slider 7 structure a certain rigidity) of the inner display screen 1. The slider 7 slides in conjunction with the groove 6, that is, the slider 7 and the groove 6 form a sliding pair. By the linear sliding of the slider 7 in the groove 6, the position of the inner display screen 1 and the outer touch screen 2 in the frame 3 can be finely adjusted, thereby effectively compensating for manufacturing and assembly tolerances.
[0029] To fix the adjusted screen position, the bottom of the slide groove 6 is provided with an elongated threaded hole 8, and the corresponding position of the slider 7 is provided with a through hole 9. After the screen position is adjusted, the slider 7 is fixed in the slide groove 6 by screwing through the through hole 9 and screwing it into the elongated threaded hole 8, thereby achieving precise positioning of the screen assembly.
[0030] The elastic filler layer 5 adopts a discontinuous structure, consisting of multiple elastic filler segments surrounding the contact surface between the frame 3 and the screen. The filler segments are made of elastic materials such as polyurethane foam or silicone, and fill the gap between the frame 3 and the screen after the screen assembly is assembled. When the device is subjected to external impact, the elastic filler segments absorb energy through deformation, preventing damage to the inner display screen 1 and the outer touch screen 2 due to stress concentration.
[0031] The elastic filler segment is embedded into the gap during screen installation. The polyurethane foam or silicone material has good elasticity and compressibility. After the screen is installed, the elastic filler segment will be compressed by 15%-25% under the pressure of the screen and frame 3. Thanks to the material's own resilience, it tightly adheres to the surfaces of the screen and frame 3, thus achieving seamless filling. When the device is subjected to external impact, the elastic filler segment absorbs energy through deformation, preventing damage to the inner display screen 1 and the outer touch screen 2 due to stress concentration. Alternatively, during embedding, it can be further secured using double-sided adhesive or other bonding methods.
[0032] In the actual assembly process, the outer touch screen 2 is first adhered to the inner display screen 1 using an optical adhesive layer, forming the screen assembly. Because the optical adhesive layer has a certain degree of fluidity before curing, minor adjustments can be made between the outer touch screen 2 and the inner display screen 1 to ensure their alignment accuracy. Next, the slider 7 on the edge of the inner display screen 1 is aligned with the groove 6 of the frame 3 and inserted, then slid along the groove 6 to adjust the position of the screen assembly within the frame 3 until the display area is centered and the border is uniform. After confirming the position is correct, connecting screws are passed through the through-hole 9 of the slider 7 and tightened into the elongated threaded hole 8 at the bottom of the groove 6. Finally, an elastic filler section is inserted into the gap between the frame 3 and the screen assembly, using its elasticity to fill the gap and provide cushioning protection, completing the assembly of the screen assembly.
[0033] In summary, through the above structural design, the screen assembly of this utility model has the following advantages:
[0034] Adjustability: Through the cooperation of slider 7 and slide groove 6, the positions of the inner display screen 1 and the outer touch screen 2 can be finely adjusted during the assembly process, effectively solving problems such as display area offset and uneven bezel width caused by manufacturing tolerances.
[0035] Shock absorption and cushioning: The elastic filling layer 5 can effectively absorb external impact, reduce stress concentration and damage to the inner display screen 1 and the outer touch screen 2, and improve the impact resistance of the screen assembly.
[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
