Description

Technical Field

[0001] This utility model relates to a touch screen, specifically a touch screen with protective functions. Background Technology

[0002] A touch screen is a sensory liquid crystal display device that can receive input signals such as touch. When a graphic button on the screen is touched, the tactile 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 screen.

[0003] Existing touchscreens typically lack protective devices around their bezels. This means that when a touchscreen is dropped or impacted by an external object, it can only rely on a protective glass layer attached to its surface for protection. This protective glass is prone to cracking under pressure, rendering the entire touchscreen unusable. Therefore, the protective effect of existing touchscreens is relatively poor. Utility Model Content

[0004] The purpose of this invention is to provide a touch screen with protective function. When it falls or is impacted by an external object, the protruding point will be subjected to force first and then drive the inner extension strip to sink, squeezing the main body and causing multiple soft sac seats to protrude upward and play a buffering role, thereby achieving a good protective function.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a touch screen with protective function, comprising a housing and a screen body disposed on the housing, a protective mechanism disposed between the housing and the screen body, the protective mechanism comprising a sandwich frame and a protective strip fixed on the sandwich frame, the sandwich frame being a hollow cavity structure, a pressure-bearing component and an airbag disposed within the cavity of the sandwich frame, the pressure-bearing component comprising an inner extension strip, on which a plurality of equally spaced protrusions are fixed, the plurality of protrusions sliding through the protective strip, the airbag comprising a main body, on which a plurality of equally spaced soft bladder seats are disposed, and the main body communicating with the soft bladder seats, the protrusions and the soft bladder seats all protruding from the upper end face of the protective strip.

[0006] Preferably, the housing includes a base plate and a protective shell fixed to the base plate. The protective shell has a U-shaped design, and the interlayer frame and protective strip are both located on the inner side of the protective shell.

[0007] Preferably, both the screen body and the interlayer frame are mounted on top of the protective shell, with the interlayer frame located on the outside of the screen body.

[0008] Preferably, there are four sets of protective mechanisms, and the four sets of protective mechanisms are set on the four sides of the screen body.

[0009] Preferably, the main capsule is fixedly bonded to the lower end face of the inner extension strip, and the main capsule is a hollow cavity structure.

[0010] Preferably, the cavity of the main capsule is filled with an inert gas, and the gas pressure inside the main capsule is slightly greater than one standard atmosphere; specifically, it can be 1.02 times or 1.05 times one standard atmosphere.

[0011] Preferably, the inner extension strip has multiple gaps, and multiple soft bladder seats pass through the multiple gaps respectively.

[0012] Preferably, the height values ​​of the protrusion, the soft pad, and the screen body decrease sequentially; this allows the protrusion to come into contact with external objects first, thus bearing the pressure first, while both the protrusion and the soft pad can protect the screen body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, by setting a protective mechanism on the outside of the screen body, with the protrusion in the protective mechanism being higher than the surface of the screen body, when the touch screen falls, the screen body will not come into contact with the external object first, but rather a certain protrusion will come into contact with the external object first. After the protrusion is subjected to force, the inner extension strip will sink, squeezing the main body and causing multiple soft pouches to protrude upward. Since the soft pouches are soft, they can both buffer the pressure and protrude from the surface of the screen body, thus providing good protection. Attached Figure Description

[0022] Please see Figures 1 to 4 The present invention provides an embodiment of a touch screen with protective function, including a housing 1 and a screen body 2 disposed on the housing 1. The housing 1 includes a base plate 11 and a protective shell 12 fixed on the base plate 11. The protective shell 12 is designed in the shape of a square. A protective mechanism 3 is provided between the housing 1 and the screen body 2. A total of four sets of protective mechanisms 3 are provided, and the four sets of protective mechanisms 3 are disposed on the four sides of the frame of the screen body 2.

[0023] The protective mechanism 3 includes a sandwich frame 31 and a protective strip 32 fixed on the sandwich frame 31. The screen body 2 and the sandwich frame 31 are both installed above the protective shell 12. The sandwich frame 31 and the protective strip 32 are both located on the inner side of the protective shell 12. The sandwich frame 31 is located on the outer side of the screen body 2. The sandwich frame 31 is a hollow cavity structure. A pressure-bearing component 33 and an airbag 34 are provided in the cavity of the sandwich frame 31. The pressure-bearing component 33 includes an inner extension strip 331. Multiple protrusions 332 are fixed on the inner extension strip 331 and are evenly distributed. The multiple protrusions 332 slide through the protective strip 32. Multiple gaps 333 are provided on the inner extension strip 331.

[0024] The airbag 34 includes a main body 341, on which multiple equally spaced soft capsule seats 342 are disposed, and the main body 341 communicates with the soft capsule seats 342. The multiple soft capsule seats 342 pass through multiple gaps 333 respectively. The main body 341 is fixedly bonded to the lower end face of the inner extension strip 331, and the main body 341 is a hollow cavity structure. An inert gas is disposed inside the cavity of the main body 341, and the gas inside the main body 341... The pressure value is slightly greater than that of a standard atmosphere, specifically 1.02 or 1.05 times that of a standard atmosphere. Both the protrusion 332 and the soft bladder 342 protrude from the upper surface of the protective strip 32. The height values ​​of the protrusion 332, the soft bladder 342 and the screen body 2 decrease sequentially, so that the protrusion 332 can come into contact with external objects first and thus bear the pressure first. At the same time, both the protrusion 332 and the soft bladder 342 can protect the screen body 2.

[0025] In the event of accidental drop or impact from an external object during use, the multiple protrusions 332 on the outer side of the screen body 2 will first come into contact with the external object. Under the pressure of the external object, the protrusions 332 will contract into the cavity of the interlayer frame 31, allowing the inner extension strip 331 to apply pressure to the main bladder 341. The gas inside the main bladder 341 will extend into the multiple soft bladder seats 342, causing the soft bladder seats 342 to protrude outward, thereby providing a buffering and protective effect for the screen body 2.

[0026] 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 illustrative 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
