Resistive touch screen device with buffer protection

Abstract

This utility model discloses a resistive touchscreen device with buffer protection, relating to the technical field of resistive touchscreen devices, including a connecting frame, a connecting structure, and a buffer structure. First, a fixing block is aligned with the opening of the connecting frame and pushed into the opening. During this process, the connecting plate gradually approaches the fixing frame as the fixing block moves, eventually fully embedding into the recess. Simultaneously, the raised buttons on the top and bottom of the connecting plate compress the springs due to pressure from the inner wall of the recess. When the connecting plate is fully inserted into the recess, the raised buttons are no longer compressed and pop outwards under the elastic action of the springs, precisely locking into the corresponding slots on the fixing frame. This completes the fixing of the fixing block and the connecting structure, thereby achieving a stable connection between the resistive touchscreen body and the connecting structure. Pressing the raised button causes its compressed spring to disengage from the slot, pulling the connecting block pulls the connecting plate out of the recess, allowing the fixing block and the resistive touchscreen body to be removed from the opening.

Description

Technical Field

[0001] This utility model relates to the technical field of resistive touch screen devices, specifically a resistive touch screen device with buffer protection. Background Technology

[0002] A resistive touchscreen device is a touch-sensitive device that uses pressing the screen to bring two internal conductive films into contact, thereby enabling signal transmission and input of operation commands. Its core consists of a touch layer, a conductive layer, a base layer, and a driving circuit. It is characterized by low cost, strong compatibility, and operability using various objects such as pens or fingers. This device is primarily used for human-computer interaction, allowing users to perform clicks, swipes, and inputs by touching the screen, replacing traditional physical buttons and simplifying the operation process. Due to these practical characteristics, resistive touchscreen devices have a wide range of applications in various fields. Specifically, in industrial control, its wear-resistant and environmentally adaptable properties make it commonly used in the control panels of CNC machine tools and industrial displays, facilitating quick command input by operators on the production floor. In consumer electronics, initially limited by cost and technological maturity, portable devices such as mobile phones, MP3 players, and electronic dictionaries often adopted this type of touchscreen, meeting the public's demand for simple touch operation. In medical equipment, its precise touch response is compatible with the parameter adjustment interfaces of devices such as electrocardiographs and ultrasound diagnostic instruments, meeting the precise operation requirements in medical scenarios. In commercial equipment… In the field of equipment, resistive touch screen devices are widely used in self-service terminals such as ATMs, self-service ticketing machines, and POS cash registers, facilitating users to complete inquiries and payments independently. Furthermore, resistive touch screen devices also occupy a certain market share in smart home control panels and automotive central control screens due to their stable performance. However, existing resistive touch screen devices have several drawbacks. Firstly, in high-frequency use scenarios such as industrial and commercial applications, touch screen devices are often subjected to external impacts such as equipment handling and tool collisions, leading to screen cracks, conductive layer peeling, and touch malfunctions. Secondly, during transportation, consumer electronics and medical equipment are prone to friction and wear between the screen corners and the outer casing if subjected to bumps and vibrations, affecting the device's appearance and lifespan. Thirdly, existing touch screens and mounting frames are mostly rigidly connected, lacking shock absorption and buffering designs. Once subjected to external forces, the impact is directly transmitted to the screen body, easily causing hardware damage and potentially leading to chain reactions such as industrial production interruptions and medical operation delays, increasing equipment maintenance costs and usage risks. Therefore, those skilled in the art have provided resistive touch screen devices with buffer protection to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a resistive touchscreen device with buffer protection to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A resistive touch screen device with buffer protection includes a connecting frame, a connecting structure, and a buffer structure. The connecting frame has an opening on one side and a connecting groove on the other side of the opening. Two sliding grooves are provided at the two edges of one side of the inner wall of the connecting groove. The connecting structure is slidably connected in the sliding groove. The buffer structure is fixedly connected to the inner walls on both sides of the opening.

[0005] As a further embodiment of this utility model: the connecting structure includes a connecting block, a connecting plate, and a raised button. Two slides corresponding to the slide groove are fixedly connected to one side of the connecting block, and the slides are slidably connected to the slide groove. A connecting plate is fixedly connected to the middle of one side of the connecting block, and the top and bottom of the connecting plate are movably connected to the raised button by springs.

[0006] As a further embodiment of this utility model: the buffer structure includes a buffer plate, a rubber plate, a damping spring, and a sliding frame. The rubber plate is fixedly connected to one side of the buffer plate, and two sliding frames are fixedly connected to the side of the buffer plate away from the rubber plate. The inner walls of the sliding frames are all fixedly connected to damping springs.

[0007] As a further improvement of this utility model: two sliding grooves are provided on the inner walls of both sides of the opening, which correspond to the sliding frames on the buffer structure, and the sliding grooves are slidably connected to the sliding frames, and the damping spring is fixedly connected to the inner wall of the opening on the side away from the sliding frames.

[0008] As a further improvement of this utility model: a fixing block is embedded in the opening, and a resistive touch screen body is fixedly connected to one side of the fixing block. Protective corners are fixedly connected to the four corners of the resistive touch screen body.

[0009] As a further improvement of this utility model, the fixing block is fixedly connected to two edges on the side away from the resistive touch screen body.

[0010] As a further improvement of this utility model: two mounting plates are fixedly connected to the top and bottom of the connecting frame, and each mounting plate is provided with mounting holes.

[0011] As a further improvement of this utility model: a groove corresponding to the connecting plate on the connecting structure is provided in the middle of one side of the fixing frame, and the groove is embedded in the connecting plate. A slot corresponding to the raised button is provided on both sides of the groove on the fixing frame, and the slot is snapped in place with the raised button.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In use, first, align the fixing block with the opening of the connecting frame, and push the fixing block horizontally into the opening. During this process, the connecting plate of the connecting structure gradually moves closer to the fixing frame as the fixing block moves, and finally fully embeds into the groove on one side of the fixing frame. At the same time, the raised buttons on the top and bottom of the connecting plate are compressed by the inner wall of the groove, compressing the springs. When the connecting plate is fully inserted into the groove, the raised buttons are no longer compressed and pop out under the elastic action of the spring, accurately locking into the slots on the fixing frame corresponding to the raised buttons. This completes the fixing of the fixing block and the connecting structure. Then, through the fixing relationship between the fixing block and the resistive touch screen body, a stable connection between the resistive touch screen body and the connecting structure is achieved. To disassemble, simply press the raised button to disengage its compressed spring from the slot, pull the connecting block to pull the connecting plate out of the groove, and the fixing block and the resistive touch screen body can be removed from the opening. 2. The protective corners are fixed at the four corners of the resistive touch screen body to prevent the touch screen body from colliding with the opening edge of the connecting frame during assembly, which would cause the corners to break. During transportation, the corners are protected from wear caused by bumps and friction with other objects. In daily use, the corners are protected from direct impact from external objects, which could cause cracks or deformation. The protective corners of the touch screen body are protected in all directions. 3. When the resistive touchscreen is subjected to an external impact, the impact force first acts on the surface of the touchscreen body, and then is transmitted to the fixed block through the connection between the touchscreen body and the fixed block. After being subjected to force, the fixed block applies pressure to the buffer structure on both sides of the opening. The rubber plate in the buffer structure first contacts the fixed block and absorbs part of the impact force through its own elastic deformation. At the same time, under the action of pressure, the buffer plate drives the sliding frame to move along the sliding groove on the inner wall of the opening, which compresses the damping spring in the sliding frame. The damping spring further absorbs and consumes the remaining impact force through elastic deformation, thereby greatly reducing the direct effect of the impact force on the resistive touchscreen body and preventing the touchscreen body from being damaged due to excessive force.

[0020] 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.

[0021] Example 1 Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment provides a resistive touchscreen device with buffer protection, including a connecting frame 3, a connecting structure 5, and a buffer structure 6. The connecting frame 3 has an opening 13 on one side, and a connecting groove 12 on the other side. Two sliding grooves 11 are formed at each of the two edges of the inner wall of the connecting groove 12, and the connecting structure 5 is slidably connected within the sliding grooves 11. The buffer structure 6 is fixedly connected to the inner walls on both sides of the opening 13. Two sliding grooves 14 are formed on the inner walls on both sides of the opening 13, corresponding to the sliding frames 64 on the buffer structure 6, and the sliding grooves 14 are slidably connected to the sliding frames 64. A damping spring 63 is fixedly connected to the inner wall of the opening 13 on the side away from the sliding frames 64. A fixing block 7 is embedded in the opening 13, and a resistive touchscreen body 1 is fixedly connected to one side of the fixing block 7. Protective corner protectors 2 are fixedly connected to the four corners of the resistive touchscreen body 1, preventing the resistive touchscreen body 1 from colliding with the edges of the opening 13 of the connecting frame 3 during assembly, thus preventing corner damage. During transportation, the corners are protected from wear caused by bumps and friction with other objects. In daily use, the corners are protected from direct impacts from external objects, preventing cracks or deformation. The corners of the resistive touch screen body 1 are protected in all directions. The fixing block 7 is fixedly connected to two edges on the side away from the resistive touch screen body 1. The top and bottom of the connecting frame 3 are fixedly connected to two mounting plates 4, and each mounting plate 4 has a mounting hole 15. The middle of one side of the fixing frame 8 has a groove 9 corresponding to the connecting plate 52 on the connecting structure 5, and the groove 9 is embedded in the connecting plate 52. The fixing frame 8 and the groove 9 on both sides have slots 10 corresponding to the raised button 53, and the slots 10 are snapped into the raised button 53. The fixing block 7 is aligned with the opening 13 of the connecting frame 3 and pushed horizontally into the opening 13. During this process, the connecting plate 52 of the connecting structure 5 gradually moves closer to the fixing frame 8 as the fixing block 7 moves, and finally is completely embedded in the groove 9 on one side of the fixing frame 8.

[0022] Example 2 Reference Figure 1-6This embodiment is based on the previous embodiment, but differs in that the connecting structure 5 includes a connecting block 51, a connecting plate 52, and a raised button 53. Two slides corresponding to the slide groove 11 are fixedly connected to one side of the connecting block 51, and the slides are slidably connected to the slide groove 11. The connecting plate 52 is fixedly connected to the middle of one side of the connecting block 51. The raised button 53 is movably connected to the top and bottom of the connecting plate 52 by springs. During the process of the connecting plate 52 being inserted into the groove 9, the raised button 53 will compress the spring due to the pressure of the inner wall of the groove 9. When the connecting plate 52 is fully inserted into the groove 9, the raised button 53 is no longer compressed and pops outward under the elastic action of the spring, precisely locking into the slot 10 on the fixing bracket 8 corresponding to the raised button 53. This completes the fixing of the fixing block 7 and the connecting structure 5. Furthermore, through the fixing relationship between the fixing block 7 and the resistive touch screen body 1, a stable connection between the resistive touch screen body 1 and the connecting structure 5 is achieved. During disassembly, simply press the raised button 53 to disengage its compression spring from the slot 10, pull the connecting block 51 to drive the connecting plate 52 out of the groove 9, and the fixed block 52 can be removed. The fixed block 7 and the resistive touchscreen body 1 are removed from the opening 13. The buffer structure 6 includes a buffer plate 61, a rubber plate 62, a damping spring 63, and a sliding frame 64. The rubber plate 62 is fixedly connected to one side of the buffer plate 61, and two sliding frames 64 are fixedly connected to the side of the buffer plate 61 away from the rubber plate 62. The inner wall of each sliding frame 64 is fixedly connected to a damping spring 63. When the resistive touchscreen body 1 is subjected to an external impact, the impact force first acts on the surface of the resistive touchscreen body 1, and then is transmitted to the fixed block 7 through the connection between the resistive touchscreen body 1 and the fixed block 7. After being subjected to force, the fixed block 7 applies pressure to the buffer structures 6 on both sides of the opening 13. The rubber plate 62 in the buffer structure 6 first contacts the fixed block 7 and absorbs part of the impact force through its own elastic deformation. At the same time, under the action of pressure, the buffer plate 61 drives the sliding frame 64 to move along the sliding groove 14 on the inner wall of the opening 13, so that the damping spring 63 in the sliding frame 64 is compressed. The damping spring 63 further absorbs and consumes the remaining impact force through elastic deformation, thereby greatly reducing the direct impact of the buffer impact force on the resistive touch screen body 1 and preventing the body from being damaged due to excessive force.
