Description

Technical Field

[0001] This utility model relates to the field of touch display device technology, and in particular to a high wear-resistant touch display component. Background Technology

[0002] With the development of information technology, touch display devices, such as interactive whiteboards, conference tablets, and all-in-one kiosks, have been widely used in education, commerce, public services, and many other fields. The core interaction method of these devices relies on users directly touching, writing, and wiping the screen surface with their fingers or styluses.

[0003] However, it is precisely this high frequency of physical contact that makes the screen surface an extremely vulnerable component. Long-term friction and scratching inevitably leave scratches, wear down the protective coating, and even lead to permanent stains. This damage not only severely affects display clarity and color reproduction, reducing the user's visual experience, but in some cases may also interfere with the accuracy of the touch sensor, affecting the normal use of the device.

[0004] Currently, although some high-end devices use high-hardness glass to improve the screen's scratch resistance, this does not fundamentally solve the problem. On the one hand, high-hardness glass is expensive and can still be damaged when faced with particles that are harder; on the other hand, once the screen suffers irreversible wear, the entire display module usually needs to be replaced, which is not only complex to repair but also extremely expensive, greatly increasing the long-term ownership cost of the device.

[0005] Therefore, this invention proposes a highly wear-resistant touch display component to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems of easy wear and tear on the screen surface, short service life and high maintenance cost of existing touch display components, this utility model aims to provide a highly wear-resistant touch display component with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a high wear-resistant touch display component, including: an outer bracket, an inner bracket, and a touch screen fixedly connected to the inner bracket; as well as a fixing box, a worm gear, a fixed axis, a rocker arm, a worm wheel, a gear, a rack, a screen protector, and a magnet.

[0008] The component consists of a detachable screen protection structure formed by a screen protector and magnets, and a complete lifting transmission mechanism consisting of a rocker arm, worm gear, worm wheel, fixed shaft, gears and racks.

[0009] Furthermore, the inner bracket is slidably connected to the outer bracket, the fixed box is fixedly connected to the outer bracket, the worm and the fixed shaft are rotatably connected inside the fixed box, the rocker arm is fixedly connected to one end of the worm that extends out of the fixed box, the worm wheel and the gear are fixedly connected to the fixed shaft, the worm wheel meshes with the worm, the rack is fixedly connected to one side of the inner bracket and meshes with the gear, and the screen protector is detachably adsorbed onto the surface of the touch screen by magnets set on itself and the touch screen.

[0010] Preferably, both the worm gear and the gear are fixed to the surface of the fixed shaft.

[0011] Preferably, the worm gear is rotatably arranged by penetrating the wall of the fixed box.

[0012] Preferably, both the touch screen and the protective film have grooves on both sides, and the magnet is fixed in the groove to achieve embedded installation of the magnet and ensure the flatness of the bonding surface.

[0013] Preferably, a handle is fixedly connected to the bottom surface of the screen protector to facilitate the user in removing or installing the screen protector.

[0014] Preferably, the high wear-resistant touch display component further includes a base, and the outer bracket is fixedly connected to the upper surface of the base to form a stable overall support frame.

[0015] Preferably, the bottom surface of the base is fixedly connected with casters to facilitate the movement of the entire device; further, the number of casters is four, evenly distributed on the bottom surface of the base, to provide stable and flexible movement support.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that touch screens are easily scratched and worn during use, resulting in short service life and high maintenance costs, by setting a protective film that can be magnetically attached to the surface of the touch screen. It achieves the technical effect of concentrating wear on the replaceable protective film, effectively protecting the touch screen body, and significantly improving the wear resistance and maintainability of the components.

[0018] 2. This utility model solves the problem of fixed height of existing touch display devices, which cannot adapt to users of different heights and diverse application scenarios, by setting up a lifting transmission system that links a rocker arm, a worm gear mechanism, and a gear rack mechanism. It achieves the technical effect of allowing users to easily adjust the screen height according to their needs, and using the self-locking characteristics of the worm gear to ensure stable and reliable position after adjustment, thereby improving the human-computer interaction friendliness and safety of the device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Example:

[0026] Please refer to Figures 1 to 3 This utility model provides a highly wear-resistant touch display component, which aims to solve the problems of existing touch display devices having easily worn screens and fixed heights, making them unable to adapt to different usage scenarios.

[0027] like Figure 1 As shown, the high wear-resistant touch display assembly includes a base 1, an outer bracket 2 fixedly connected to the upper surface of the base 1, an inner bracket 10 slidably connected to the outer bracket 2, and a touch screen 11 fixedly connected to the upper part of the inner bracket 10. The assembly achieves the lifting and lowering of the inner bracket 10 relative to the outer bracket 2 by setting a height adjustment mechanism, and achieves wear-resistant protection for the touch screen 11 by setting a screen protection mechanism.

[0028] like Figure 1 and Figure 2As shown, the height adjustment mechanism includes a fixed box 3 fixedly connected to the outer bracket 2. A worm 5 and a fixed shaft 7 are rotatably connected inside the fixed box 3. One end of the worm 5 passes through the fixed box 3 and is fixedly connected to a rocker arm 4. A worm wheel 6 and a gear 8 that mesh with the worm 5 are fixedly connected to the fixed shaft 7. A rack 9 that meshes with the gear 8 is fixedly connected to one side of the inner bracket 10. By shaking the rocker arm 4, power is transmitted to the rack 9 via the worm 5, worm wheel 6, fixed shaft 7, and gear 8, thereby driving the inner bracket 10 and the touch screen 11 to move up and down.

[0029] like Figure 1 and Figure 3 As shown, the screen protection mechanism includes a screen protector 12 and a magnet 13 disposed on the screen protector 12 and the touch screen 11. The screen protector 12 is detachably attached to the display surface of the touch screen 11 by the magnetic force of the magnet 13. A grip 14 for easy removal and placement is also fixedly connected to the bottom surface of the screen protector 12.

[0030] To solve the above-mentioned technical problems, the high wear-resistant touch display component achieves stable height adjustment of the touch screen 11 through an integrated mechanical transmission mechanism, and the components of the mechanism form a precise structural fit and connection relationship.

[0031] Please refer to the following carefully. Figure 1 and Figure 2 The fixed box 3 is fixedly connected to the upper part of the outer bracket 2, and its interior provides installation space and protection for the transmission components. The worm 5 penetrates the wall of the fixed box 3 and is rotatably connected inside the fixed box 3. One end of the worm 5 extends out of the fixed box 3 and is fixedly connected to the rocker arm 4. The fixed shaft 7 is rotatably connected inside the fixed box 3, and the surface of the fixed shaft 7 is fixedly connected to the worm wheel 6 and the gear 8. The worm wheel 6 meshes with the worm 5, and the gear 8 meshes with the rack 9 fixed on one side of the inner bracket 10. When the rocker arm 4 is rocked, the rocker arm 4 drives the worm 5 to rotate, and the worm 5 drives the worm wheel 6 through meshing transmission. The worm gear 6 and the gear 8 are both fixed to the fixed shaft 7. Therefore, the rotation of the worm gear 6 will drive the gear 8 to rotate synchronously through the fixed shaft 7. The rotating gear 8 will then drive the rack 9 to produce a linear motion in the up and down direction through meshing. The inner bracket 10, which is fixedly connected to the rack 9, will rise and fall synchronously, thereby driving the touch screen 11 fixed on it to achieve height adjustment. The worm gear transmission structure here ensures the smoothness of the adjustment process, and by utilizing its self-locking characteristic, the touch screen 11 can reliably maintain its position after being adjusted to any height, and will not slide down due to its own gravity.

[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0033] As a preferred implementation method, please refer to Figure 2In order to achieve reliable synchronous transmission, both the worm gear 6 and the gear 8 are fixedly connected to the surface of the fixed shaft 7. This coaxial fixed connection ensures that the rotation of the worm gear 6 can drive the gear 8 to rotate synchronously at the same angular velocity.

[0034] As a preferred embodiment, the worm 5 is rotatably mounted through the wall of the fixed box 3, with one end inside the fixed box 3 meshing with the worm wheel 6, and the other end extending out of the fixed box 3 and connected to the rocker arm 4. This arrangement not only realizes the transmission of external operating force to the internal transmission mechanism, but also uses the closed structure of the fixed box 3 to protect the internal worm gear meshing pair.

[0035] As a preferred implementation method, please refer to Figure 3 In order to achieve a stable installation of the magnet 13, grooves are provided on both sides of the touch screen 11 and the screen protector 12. The magnet 13 is fixed in the corresponding groove. By embedding the magnet 13 into the groove, the surface of the magnet 13 can be flush with the side wall of the groove, ensuring the flatness of the screen protector 12 and the touch screen 11 when they are attached.

[0036] As a preferred embodiment, in order to facilitate the installation and removal of the screen protector 12 by the user, a handle 14 is fixedly connected to the bottom surface of the screen protector 12, and the user can conveniently operate the screen protector 12 by gripping the handle 14.

[0037] As a preferred implementation method, please refer to Figure 1 In order to enable the entire device to move and provide stable support, the component also includes a base 1, and an outer bracket 2 is fixedly connected to the upper surface of the base 1 to form the support frame of the entire device; furthermore, the bottom surface of the base 1 is fixedly connected with casters, so that the entire device can move freely; more specifically, there are four casters, which are evenly distributed at the four corners of the bottom surface of the base 1, providing stable and flexible movement support for the device.

[0038] Working principle: When the height of the touch screen 11 needs to be adjusted, the operator manually cranks the rocker arm 4. The rocker arm 4 drives the worm gear 5 to rotate. Since the worm gear 5 and the worm wheel 6 mesh with each other, the rotation of the worm gear 5 will drive the worm wheel 6 to rotate. Since the worm wheel 6 and the gear 8 are both fixedly connected to the fixed shaft 7, the fixed shaft 7 rotates synchronously with the worm wheel 6 and drives the gear 8 to rotate. The rotating gear 8 meshes with the rack 9 fixed on the inner bracket 10, converting the rotational motion into linear motion, thereby driving the rack 9 to drive the inner bracket 10 to slide up and down along the guide of the outer bracket 2. Since the touch screen 11 is fixed to the inner bracket 10, the height of the touch screen 11 can be smoothly adjusted. After the rocker arm 4 is stopped, the transmission pair of the worm gear 5 and the worm wheel 6, due to its self-locking characteristic, can prevent the inner bracket 10 from sliding down under the gravity of the touch screen 11, ensuring reliable locking of the position.

[0039] When the touchscreen 11 needs protection, the user can hold the grip 14 of the screen protector 12 and bring the screen protector 12 close to the surface of the touchscreen 11. At this time, the magnets 13 fixed on the screen protector 12 and the touchscreen 11 will attract each other due to magnetic force, thereby firmly and flatly adhering the screen protector 12 to the surface of the touchscreen 11. Touching, writing, scratching and other operations in daily use all act on the surface of the screen protector 12, effectively protecting the touchscreen 11 body underneath from wear and tear. When the screen protector 12 is severely worn or needs cleaning, the user can also hold the grip 14 and apply a pulling force to overcome the adsorption force of the magnets 13, so that the screen protector 12 can be easily removed for replacement or cleaning.

[0040] When the entire device needs to be moved, the casters on the bottom of the base 1 allow the entire component to be easily pushed to different positions, improving the device's adaptability to different scenarios.

[0041] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
