Description

Technical Field

[0001] This utility model relates to the field of capacitive screens, specifically a capacitive screen structure that is easy to install. Background Technology

[0002] Capacitive touchscreens are a mainstream touchscreen technology based on the principle of human body electric field sensing. They achieve positioning by changing the capacitance distribution of the screen when a conductive object touches it. The mainstream technology uses mutual capacitance mode to support multi-touch. Its core structure consists of protective glass, ITO conductive layer, insulating layer and substrate. It has the advantages of high sensitivity, high light transmittance and durability, and is widely used in consumer electronics, automotive systems, commercial equipment, industrial control and other fields.

[0003] A search revealed that publication number CN216084133U discloses "A Direct-Mounted Capacitive Screen Mounting Structure and Intelligent Interactive Device," which describes a frameless design with a first and second limiting surface for supporting the capacitive screen and pressing the optical film. This reduces the types and number of components in the device, thereby lowering the installation difficulty. Furthermore, this embodiment uses the second limiting surface to directly press and fix the optical film instead of the existing frame, preventing the optical film from detaching due to frame warping during transport. Based on the technical content in the aforementioned comparative documents, currently, capacitive screens are typically bonded to the mounting frame using double-sided adhesive or glass glue. However, this method has a problem: after bonding, external clamps are needed to hold and fix the screen in place, and the next processing step can only proceed after the double-sided adhesive or glass glue has dried and firmly bonded. This waiting time is typically 12-24 hours, which undoubtedly reduces the ease of installation for capacitive screens. Therefore, the inventor urgently needs to design a capacitive screen assembly that is easy to install, thereby improving the installation efficiency of capacitive screens. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a convenient capacitive screen structure to solve the technical problem that capacitive screens and mounting frames are mostly bonded with double-sided adhesive or glass glue, requiring clamps to hold them in place and wait 12-24 hours for air drying before subsequent processing, which seriously affects the convenience and efficiency of installation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conveniently installed capacitive screen structure, including a back frame, a snap-fit ​​assembly for supporting the installation of the capacitive screen is installed on one side of the back frame, the snap-fit ​​assembly includes a mounting part, a side plate is bent on one side of the mounting part, a snap-fit ​​part is formed on the upper side of the side plate near the capacitive screen, a support foot is bent at the lower end of the snap-fit ​​part, an abutting end is bent below the support foot, an abutting groove is formed between the mounting part and the side plate, the abutting end abuts against the abutting groove, a pressing part is bent on the other side of the mounting part, a support part is bent above the pressing part, and one side of the support part overlaps with the support foot; The edge of the capacitive screen overlaps the support and engages with the snap-fit ​​part.

[0006] By adopting the above technical solution, the capacitive screen can be directly attached to the support and fixed with the snap-fit ​​part without waiting for the adhesive to dry, which greatly shortens the installation cycle and improves the ease of installation of the capacitive screen. The mounting part, side plate, snap-fit ​​part, support foot, and abutment end of the snap-fit ​​component form a mutually cooperating structure through bending. The abutment end abuts against the abutment groove, and the support part overlaps with the support foot, forming multi-dimensional support and limiting, ensuring that the capacitive screen is accurately and stably positioned after installation, avoiding the displacement problem that may occur in traditional installation.

[0007] Furthermore, the mounting part is bolted to the back frame.

[0008] By adopting the above technical solutions, it is ensured that the snap-fit ​​components will not loosen or shift during long-term use or transportation, thereby ensuring the installation stability of the capacitive screen. The detachability of the bolt connection also provides convenience for later maintenance. When it is necessary to inspect or replace the snap-fit ​​components or the capacitive screen, the components can be separated simply by removing the bolts. The operation is simple and convenient, without damaging the back frame or snap-fit ​​components.

[0009] Furthermore, an optical film is bolted to the inner side of the back frame, the pressing part abuts against the optical film, and foam is provided between the pressing part and the optical film.

[0010] By adopting the above technical solution, the fixing effect is further enhanced, replacing the method of relying on the middle frame to press in the existing technology. This effectively avoids the problem of optical film jumping off due to the warping of the middle frame, and ensures the performance of the optical film.

[0011] Furthermore, the capacitive screen and the support are bonded together with double-sided adhesive.

[0012] By adopting the above technical solution, double-sided adhesive can fill the tiny gaps between the capacitive screen and the support, making the two adhere more tightly. Combined with the snap-fit ​​fixing of the snap-fit ​​part, it greatly improves the stability of the capacitive screen installation and ensures that the capacitive screen can maintain its position stability even after long-term use or slight vibration.

[0013] Furthermore, a baffle plate is bent on one side of the back frame, and the baffle plate abuts against the abutment groove to cover the mounting components.

[0014] By adopting the above technical solution, the mounting components and related connection structures of the snap-fit ​​assembly can be effectively shielded, preventing these components from being directly exposed to the external environment. This prevents dust, impurities, moisture, etc. from entering the interior and causing corrosion, pollution, or damage to the mounting components, thereby protecting the integrity and stability of the internal structure and extending the service life of the entire capacitive screen structure. The shielding effect of the shielding plate can also reduce the interference of external factors on the mounting components, ensuring that the snap-fit ​​effect and connection stability of the snap-fit ​​assembly are not affected.

[0015] Furthermore, when disassembling the capacitive screen, the side plate is bent, and the side plate deforms with respect to the mounting part, causing the edge of the capacitive screen to detach from the snap-fit ​​part.

[0016] By adopting the above technical solution, when it is necessary to disassemble the capacitive screen, simply bend the side plate manually to deform the side plate and the mounting part, thereby allowing the edge of the capacitive screen to detach from the snap-fit ​​part. There is no need to use complex tools such as screwdrivers and wrenches, which greatly reduces the difficulty and time cost of disassembly operations and facilitates the later maintenance of the capacitive screen. This convenient disassembly method is especially suitable for scenarios that require frequent maintenance and significantly improves maintenance efficiency.

[0017] Furthermore, a limiting plate is bent between the mounting part and the side plate, and a connecting plate is bent below the supporting leg, with the connecting plate overlapping the limiting plate.

[0018] By adopting the above technical solution, a second implementation method is provided to ensure that the support foot always maintains a stable support state, thereby ensuring the snap-fit ​​effect of the snap-fit ​​part on the capacitive screen and avoiding the capacitive screen from loosening or falling off due to the displacement of the support foot, which significantly enhances the structural stability and load-bearing capacity of the snap-fit ​​component.

[0019] In summary, the present invention has the following main advantages: 1. This utility model achieves convenient installation of capacitive screen through the cooperation of back frame and snap-fit ​​component. The capacitive screen is attached to the support part and snap-fitted to the snap-fit ​​part. Double-sided tape is used for auxiliary fixation. It does not require the long drying time of traditional double-sided tape or glass glue, nor does it require external fixing clips, which greatly improves the installation efficiency. 2. In this utility model, the capacitive screen can be detached from the snap-fit ​​part by bending the side plate to deform it, without the need for complicated tools, thus avoiding damage to the parts and improving the convenience of maintenance.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Example 1:

[0023] A convenient capacitive touchscreen structure, such as Figure 1-3 As shown, the back frame 2 is included. A snap-fit ​​assembly 4 for supporting the installation of the capacitive screen 1 is installed on one side of the back frame 2. The snap-fit ​​assembly 4 includes a mounting part 401. A side plate 404 is bent on one side of the mounting part 401. A snap-fit ​​part 405 is formed on the upper side of the side plate 404 near the capacitive screen 1. A support foot 406 is bent at the lower end of the snap-fit ​​part 405. An abutting end 407 is bent below the support foot 406. An abutting groove 408 is formed between the mounting part 401 and the side plate 404. The abutting end 407 abuts against the abutting groove 408. A pressing part 402 is bent on the other side of the mounting part 401. A support part 403 is bent above the pressing part 402. One side of the support part 403 overlaps with the support foot 406. The edge of the capacitive screen 1 overlaps the support part 403 and is engaged with the snap-fit ​​part 405.

[0024] The capacitive screen 1 can be directly attached to the support part 403 and snapped into place by the snap-fit ​​part 405, eliminating the need to wait for the adhesive to dry, greatly shortening the installation cycle and improving the ease of installation of the capacitive screen 1. The mounting part 401, side plate 404, snap-fit ​​part 405, support foot 406, and abutment end 407 of the snap-fit ​​assembly 4 form a mutually cooperating structure through bending. The abutment end 407 abuts against the abutment groove 408, and the support part 403 overlaps with the support foot 406, forming multi-dimensional support and limiting, ensuring that the capacitive screen 1 is accurately and stably positioned after installation, avoiding the displacement problems that may occur in traditional installation. At the same time, this integrated snap-fit ​​setting reduces the use of additional fixing parts, simplifies the installation steps, and can be completed without professional personnel, lowering the installation threshold.

[0025] See Figure 1 , Figure 2 The mounting part 401 is bolted to the back frame 2 to ensure that the snap-fit ​​component 4 will not loosen or shift during long-term use or transportation, thereby ensuring the installation stability of the capacitive screen 1. The detachability of the bolt connection also provides convenience for later maintenance. When it is necessary to inspect or replace the snap-fit ​​component 4 or the capacitive screen 1, the components can be separated simply by removing the bolts. The operation is simple and convenient, without damaging the back frame 2 or the snap-fit ​​component 4. At the same time, the bolt connection has strong versatility and can be adapted to back frames 2 and snap-fit ​​components 4 of different specifications, reducing the adaptation difficulty in the manufacturing process. Moreover, the tightening force of the bolts can be adjusted as needed, and the connection strength can be adjusted according to the actual use scenario.

[0026] See Figure 1 , Figure 2 An optical diaphragm 3 is bolted to the inner side of the back frame 2. The pressing part 402 abuts against the optical diaphragm 3, and a foam 6 is placed between the pressing part 402 and the optical diaphragm 3 to further enhance the fixing effect. This replaces the method of relying on the middle frame for clamping in the prior art, effectively avoiding the problem of the optical diaphragm 3 jumping off due to the warping of the middle frame, and ensuring the performance of the optical diaphragm 3. At the same time, the foam 6 placed between the pressing part 402 and the optical diaphragm 3 plays a good role in buffering and protection. The foam 6 is soft and can relieve the pressure of the pressing part 402 on the optical diaphragm 3, avoid hard contact that may cause scratches on the surface of the optical diaphragm 3 or damage to the internal structure, and extend the service life of the optical diaphragm 3.

[0027] See Figure 1 , Figure 2The capacitive screen 1 and the support part 403 are bonded together by double-sided adhesive 5. The double-sided adhesive 5 can fill the tiny gaps between the capacitive screen 1 and the support part 403, making the two fit more tightly. Together with the snap-fit ​​fixation of the snap-fit ​​part 405, it greatly improves the stability of the capacitive screen 1 installation, ensuring that the capacitive screen 1 can maintain its position stability even after long-term use or slight vibration. The adhesive properties of the double-sided adhesive 5 can also play a certain buffering role, reducing the impact of external impact on the capacitive screen 1 and reducing the risk of damage to the capacitive screen 1 due to vibration.

[0028] See Figure 1 , Figure 2 A baffle plate is bent on one side of the back frame 2 and abuts against the abutment groove 408. It is used to cover the mounting components and can effectively cover the mounting components and related connection structures of the snap-fit ​​assembly 4, preventing these components from being directly exposed to the external environment. This prevents dust, impurities, moisture, etc. from entering the interior and causing corrosion, pollution or damage to the mounting components, thereby protecting the integrity and stability of the internal structure and extending the service life of the entire capacitive screen structure. The covering effect of the baffle plate can also reduce the interference of external factors on the mounting components, ensuring that the snap-fit ​​effect and connection stability of the snap-fit ​​assembly 4 are not affected. At the same time, the setting of the baffle plate makes the appearance of the device cleaner and more beautiful, hides the complex internal installation structure, improves the visual quality of the product, and meets the user's aesthetic needs for the appearance of the device.

[0029] See Figure 1 , Figure 2 , Figure 3 When disassembling the capacitive screen 1, the side plate 404 is bent, causing deformation between the side plate 404 and the mounting part 401, thus separating the edge of the capacitive screen 1 from the snap-fit ​​part 405. When it is necessary to disassemble the capacitive screen 1, simply bend the side plate 404 manually to deform the side plate 404 and the mounting part 401, thereby separating the edge of the capacitive screen 1 from the snap-fit ​​part 405. This eliminates the need for complex tools such as screwdrivers and wrenches, greatly reducing the difficulty and time cost of disassembly and facilitating subsequent maintenance of the capacitive screen 1. This convenient disassembly method is especially suitable for scenarios requiring frequent maintenance, significantly improving maintenance efficiency. At the same time, the deformable design of the side plate 404 fully considers the protection of components during disassembly, avoiding the problem of damage to the capacitive screen 1, back frame 2, or snap-fit ​​component 4 caused by the violent disassembly required by traditional adhesive methods, ensuring the reusability of each component and reducing maintenance costs. Example 2:

[0030] See Figure 3A limiting plate 409 is bent between the mounting part 401 and the side plate 404. A connecting plate 410 is bent below the support foot 406. The connecting plate 410 overlaps the limiting plate 409, providing a second implementation form. This ensures that the support foot 406 always maintains a stable support state, thereby ensuring the snap-fit ​​effect of the snap-fit ​​part 405 on the capacitive screen 1. It also prevents the capacitive screen 1 from loosening or falling off due to the displacement of the support foot 406, significantly enhancing the structural stability and load-bearing capacity of the snap-fit ​​assembly 4. At the same time, the overlapping arrangement of the limiting plate 409 and the connecting plate 410 further optimizes the force-bearing structure of the snap-fit ​​assembly 4, making the cooperation between the components tighter and the overall structure more robust. This allows it to better resist vibration and collision during transportation and external force during use, ensuring that the installation accuracy and stability of the capacitive screen 1 remain in good condition for a long time.

[0031] The implementation principle of this embodiment is as follows: First, the optical film 3 is installed inside the back frame 2. Then, the mounting part 401 of the snap-fit ​​assembly 4 is fixed to the back frame 2. The abutting end 407 abuts against the abutting groove 408 formed by the mounting part 401 and the side plate 404. The pressing part 402 and the supporting part 403 bent on the other side of the mounting part 401 are also in place at the same time. The supporting part 403 overlaps with the supporting foot 406. At the same time, the pressing part 402 is abutted and fixed by the foam 6. Then, the edge of the capacitive screen 1 is overlapped on the supporting part 403 and glued with double-sided tape 5. At the same time, it is snapped and fixed with the snap-fit ​​part 405. The shielding plate on one side of the back frame 2 covers the mounting components. During disassembly, bend the side plate 404 to deform it between it and the mounting part 401, so that the edge of the capacitive screen 1 can be separated from the snap-fit ​​part 405, and the disassembly can be completed. In the second embodiment, the limiting plate 409 between the mounting part 401 and the side plate 404 overlaps with the connecting plate 410 below the support foot 406 to enhance stability.
