Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, and in particular to a touch screen with a protective structure. Background Technology

[0002] A touchscreen, also known as a touch panel, is a sensor-based liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the haptic feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. As a latest computer input device, the touchscreen is currently the simplest, most convenient, and most natural way for humans to interact with computers.

[0003] Currently, touchscreens are typically placed on desktops or workbenches during use. However, when a touchscreen is bumped or accidentally impacted, it is very easy for it to fall off the desktop or workbench to the ground. Although the surface of the touchscreen is usually covered with a tempered glass film to prevent the screen from breaking, if the corner of the touchscreen contacts the ground first, the small contact area between the corner and the ground will generate higher local pressure, which will directly lead to the screen breaking. Utility Model Content

[0004] The main purpose of this invention is to provide a touch screen with a protective structure, which aims to reduce the risk of the touch screen breaking when it is dropped from a height.

[0005] To achieve the above objectives, this utility model proposes a touch screen with a protective structure, including a housing and protective blocks at the four corners of the housing. The thickness of the protective blocks is greater than the thickness of the housing, and each protective block has an accommodating groove inside. The four corners of the housing are respectively located inside the corresponding accommodating grooves. One side of each protective block is connected to a fixing plate through an extension component. The fixing plate is located on the back of the housing, and there is a gap between the fixing plate and the back of the housing.

[0006] In one possible implementation, the extension assembly includes an extension plate disposed at the corner of the fixed plate, a connecting plate whose one end is fixedly connected to the protective block, and an elastic member. The extension plate is fixedly connected to the fixed plate, and a sliding groove is provided inside the extension plate. The other end of the connecting plate is slidably connected to the inner wall of the sliding groove. One end of the elastic member abuts against the side of the sliding groove away from the fixed plate, and the other end of the elastic member is fixedly connected to the connecting plate.

[0007] In one possible implementation, a guide rod is fixedly connected inside the groove, the elastic element is sleeved on the outer surface of the guide rod, and one side of the connecting plate is slidably connected to the guide rod.

[0008] In one possible implementation, the guide rod has a square cross-section, and shock-absorbing pads are provided on both sides of the inner wall of the receiving groove.

[0009] In one possible implementation, the fixing plate is provided with a plurality of heat dissipation grooves.

[0010] In one possible implementation, the connecting plate includes a fixed part and a movable part that are fixedly connected to the protective block. One side of the movable part is slidably connected to the inner wall of the slide groove. The fixed part is provided with a sliding block on the side near the movable part. The movable part is provided with a sliding groove on the side near the sliding block. The sliding block is slidably connected to the inner wall of the sliding groove. The movable part is provided with a fixing component for fixing the sliding block.

[0011] In one possible implementation, the fixing component includes a fixing bolt and a washer. One side of the sliding groove is provided with a fixing groove. One side of the fixing bolt is threadedly connected to the sliding block. The diameter of the fixing bolt is smaller than the width of the fixing groove. The washer is provided with the outer surface of the movable part, and the bolt head of the fixing bolt abuts against the washer.

[0012] The technical solution of this utility model incorporates a protective block. When the touchscreen is dropped, the protective block contacts the ground first, dispersing the impact force and reducing localized pressure at the corners, thereby lowering the risk of the screen shattering due to impact. Simultaneously, the design of the protective block being thicker than the casing ensures that in the event of an accidental drop, the protective block will preferentially contact the ground, further reducing the risk of screen breakage. Furthermore, the gap between the fixing plate and the back of the casing facilitates airflow, thereby improving the touchscreen's heat dissipation. Attached Figure Description

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] Example 1:

[0023] refer to Figure 1-4 This embodiment proposes a touchscreen with a protective structure, including a housing 1 and protective blocks 101 at the four corners of the housing 1. The thickness of the protective blocks 101 is greater than the thickness of the housing 1. The protective blocks 101 can be made of silicone, which has high elasticity and flexibility, and can absorb impact energy through deformation, thereby reducing the impact on the touchscreen. In addition, silicone has good insulation properties and will not affect the internal circuitry of the touchscreen or adversely affect its performance. Simultaneously, shock-absorbing pads 109 can be provided on the inner walls of both sides of the receiving groove 102. The shock-absorbing pads 109 can buffer and absorb shocks between the housing 1 and the protective blocks 101, reducing the transmission of vibrations caused by collisions to the touchscreen and lowering the risk of screen damage.

[0024] Each protective block 101 has an internal receiving groove 102. The four corners of the housing 1 are respectively located inside the corresponding receiving groove 102. One side of each protective block 101 is connected to a fixing plate 103 through an extension component. The fixing plate 103 is located on the back of the housing 1, and there is a gap between the fixing plate 103 and the back of the housing 1. The gap allows for air circulation to facilitate heat dissipation of the touch screen.

[0025] To improve heat dissipation, several heat dissipation slots 110 are provided on the fixed plate 103 to dissipate the heat generated by the touch screen during operation, thereby avoiding the impact of heat accumulation on the performance and lifespan of the touch screen and improving the reliability and stability of the touch screen.

[0026] By setting up the protective block 101, when the touch screen is dropped, the protective block 101 will first contact the ground, disperse the impact force, reduce the local pressure at the corners, and thus reduce the risk of the screen breaking due to landing on the corners.

[0027] Furthermore, the extension assembly includes an extension plate 104 disposed at the corner of the fixed plate 103, a connecting plate 105 fixedly connected at one end to the protective block 101, and an elastic member 106. The extension plate 104 is fixedly connected to the fixed plate 103, and a sliding groove 107 is provided inside the extension plate 104. The other end of the connecting plate 105 is slidably connected to the inner wall of the sliding groove 107. One end of the elastic member 106 abuts against the side of the sliding groove 107 away from the fixed plate 103, and the other end of the elastic member 106 is fixedly connected to the connecting plate 105.

[0028] By providing an extension plate 104, a connecting plate 105, and an elastic element 106, the protective block 101 can adapt to touch screen housings 1 of different sizes to a certain extent, thereby expanding its applicability.

[0029] When the housing 1 is placed in the receiving groove 102 inside each protective block 101, since the elastic element 106 always has the ability to recover its deformation, it will continuously push the connecting plate 105 to move towards the fixing plate 103, thereby making the connection between the protective block 101 and the housing 1 tighter and reducing the possibility that the protective block 101 will detach from the housing 1 when the touch screen falls to the ground.

[0030] Furthermore, a guide rod 108 is fixedly connected inside the slide groove 107, and an elastic element 106 is sleeved on the outer surface of the guide rod 108. One side of the connecting plate 105 is slidably connected to the guide rod 108. The guide rod 108 restricts the movement direction of the connecting plate 105, allowing one end to slide stably in the slide groove 107, preventing it from shifting or misaligning during movement. This ensures the reliability and stability of the extension assembly, and also ensures that the elastic element 106 is subjected to uniform force, thereby extending the service life of the elastic element 106.

[0031] Secondly, the cross-section of the guide rod 108 is designed to be square, which can better prevent the connecting plate 105 from rotating during sliding and further enhance the stability of the structure.

[0032] Example 2:

[0033] Based on Example 1, and referring to Figure 4-5In this embodiment, to broaden the applicability of the protective block 101, the connecting plate 105 is improved. Specifically, the connecting plate 105 includes a fixed part 1051 and a movable part 1052 that are fixedly connected to the protective block 101. One side of the movable part 1052 is slidably connected to the inner wall of the slide groove 107. A sliding block 2 is provided on the side of the fixed part 1051 near the movable part 1052. A sliding groove 201 is provided on the side of the movable part 1052 near the sliding block 2. The sliding block 2 is slidably connected to the inner wall of the sliding groove 201. A fixing component for fixing the sliding block 2 is provided on the movable part 1052.

[0034] The connecting plate 105 is divided into a fixed part 1051 and a movable part 1052. Through the cooperation of the sliding block 2 and the sliding groove 201, and the setting of the fixing components, the length and angle of the connecting plate 105 can be further adjusted, so as to better adapt to touch screen housings 1 of different sizes. This avoids the problem of excessive compression of the elastic element 106 by the connecting plate 105 when the user adapts to a larger size touch screen housing 1, which would lead to damage to the elastic element 106.

[0035] When a user needs to protect the four corners of the large touchscreen housing 1, they can loosen the fixing components and then pull the protective block 101. The protective block 101 moves the movable part 1052, which in turn moves the sliding block 2 within the sliding groove 201. After adjusting to the appropriate position, the user can use the fixing components to fix the sliding block 2, and then insert the four corners of the touchscreen housing 1 into the corresponding receiving grooves 102. Since the elastic element 106 always has the force to restore its deformation, it will continuously push the movable part 1052 to move in the opposite direction, thereby clamping the touchscreen housing 1.

[0036] Specifically, the fixing component includes a fixing bolt 202 and a washer 203. A fixing groove 204 is provided on one side of the sliding groove 201. One side of the fixing bolt 202 is threadedly connected to the sliding block 2. The diameter of the fixing bolt 202 is smaller than the width of the fixing groove 204. The washer 203 is provided on the outer surface of the movable part 1052, and the bolt head of the fixing bolt 202 abuts against the washer 203.

[0037] When the length of the connecting plate 105 needs to be adjusted, the user can use a tool to loosen the fixing bolt 202, causing the side of the fixing bolt 202 to disengage from the surface of the movable part 1052. Then, the user can pull the protective block 101 to the appropriate position. After adjusting to the appropriate position, the user can use a tool to tighten the fixing bolt 202, making the side of the bolt head of the fixing bolt 202 contact the side of the movable part 1052, thus fixing the position of the sliding block 2 through friction.

[0038] The diameter of the fixing bolt 202 is designed to be smaller than the width of the fixing groove 204. This is to allow users to adjust the length of the connecting plate 105 without completely unscrewing the fixing bolt 202; they only need to disengage the bolt head from the side of the movable part 1052. This allows the sliding block 2 to move the loosened fixing bolt 202 within the fixing groove 204. Simultaneously, this design utilizes the principle of friction to fix the sliding block 2, enabling the fixing assembly to hold the sliding block 2 at any position within the fixing groove 204, thereby further expanding its applicability.
