Description

Technical Field

[0001] This utility model relates to the field of touch screen device protection technology, and in particular to an edge protection structure for touch screen devices. Background Technology

[0002] A touchscreen, also known as a touch panel, is a sensor-type liquid crystal display device that can receive input signals from 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] However, in the existing technology, the corners of existing touch screen devices are usually quite fragile and are easily damaged by impacts. When using them, protective covers are usually put on the outside of the touch screen device to protect the corners. However, existing protective covers are usually wrap-around designs. Although they can effectively protect the corners of the touch screen device, they also reduce the heat dissipation of the device, causing the device to overheat and affecting its use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide an edge protection structure for touchscreen devices.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an edge protection structure for touch screen devices, comprising: a touch screen device body, wherein a protective component is provided on the outer side of the touch screen device body, the protective component comprising two first frames, four connecting frames and two second frames, the four connecting frames being fixedly installed on the upper and lower sides of the two first frames respectively, two elastic sheets being fixedly installed on one side of each of the four connecting frames, and a limit block being fixedly installed on one side of each elastic sheet, wherein a multi-level buffer structure is provided on the inner side of the two first frames and the two second frames.

[0006] In a preferred embodiment, two slots are provided on both sides of the two second frames, and a limiting groove is formed on one side of each slot, with the slot and the limiting groove being connected.

[0007] In a preferred embodiment, one side of the limiting block is designed with an arc-shaped surface, and the limiting groove is adaptively matched with the limiting block.

[0008] In a preferred embodiment, the first frame, the connecting frame, and the second frame are all made of engineering plastics. The cross-sections of the first frame, the connecting frame, and the second frame are U-shaped. The first frame, the connecting frame, and the second frame are positioned to cover the edge of the touch screen device body.

[0009] In a preferred embodiment, the multi-level buffer structure includes a plurality of micro springs, which are respectively fixedly installed on the inner sides of the two first frames and the two second frames, and a buffer pad is fixedly installed on one end of each of the micro springs.

[0010] In a preferred embodiment, rubber connecting layers are fixedly installed on both sides of the interior of the two first frames and the two second frames, and flexible contact layers are fixedly installed on one side of the two rubber connecting layers. Several energy-absorbing blocks are fixedly installed between the two first frames and the two second frames and the four buffer pads, and the cross-section of the several energy-absorbing blocks is designed in a honeycomb structure.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. This utility model fixes the two second frames to one of the first frames by inserting the limiting block into the slot, causing the elastic sheet to deform elastically and move the limiting block into the limiting groove. Then, the other first frame is connected to the other side of the two second frames to complete the installation. The operation is simple and convenient. The non-enclosed design can effectively protect the touch screen device body and reduce contact with the touch screen device body, ensuring that the heat dissipation of the touch screen device body is not affected, thus improving the practicality of the structure.

[0013] 2. Through the multi-level buffer structure, when the touch screen device is impacted, its edges will contact the buffer pads inside the first and second frames for initial buffering. Then, several micro springs will undergo elastic deformation to absorb some energy, thus completing the second level of buffering. Finally, several energy-absorbing blocks will undergo plastic deformation to compress the pores and further dissipate energy, thereby completing the multi-level buffering operation. This effectively reduces the impact force when the touch screen device is impacted, avoids damage to the edges of the touch screen device due to excessive impact force, and improves the performance of the structure.

[0021] 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.

[0022] Example 1

[0023] like Figure 1-3 As shown, this utility model provides a technical solution: an edge protection structure for a touchscreen device, comprising: a touchscreen device body 11, a protective component 2 disposed on the outer side of the touchscreen device body 11, the protective component 2 including two first frames 21, four connecting frames 22 and two second frames 23, the four connecting frames 22 being fixedly installed on the upper and lower sides of the two first frames 21 respectively, two elastic pieces 24 being fixedly installed on one side of each of the four connecting frames 22, and limit blocks 25 being fixedly installed on one side of each elastic piece 24, and the inner sides of the two first frames 21 and the two second frames 23 being provided with There is a multi-level buffer structure 3. Two slots 26 are opened on both sides of the two second frames 23. A limiting groove 27 is formed on one side of each slot 26. The slot 26 and the limiting groove 27 are connected. One side of the limiting block 25 is designed with an arc surface. The limiting groove 27 and the limiting block 25 are adapted to each other. The first frame 21, the connecting frame 22 and the second frame 23 are all made of engineering plastic. The cross-section of the first frame 21, the connecting frame 22 and the second frame 23 is designed with a U-shape. The first frame 21, the connecting frame 22 and the second frame 23 are set to cover the edge of the touch screen device body 11.

[0024] In this embodiment, the outer surfaces of both the first frame 21 and the second frame 23 are designed with anti-slip textures. The anti-slip textures are formed by laser engraving into a dot matrix pattern, which can effectively enhance the friction between the hand and the device during use and prevent slippage. The elastic sheet 24 is made of elastic material and can bend when the limiting block 25 is inserted into the slot 26. Then, when the limiting block 25 moves to one side of the limiting groove 27, the elastic sheet 24 elastically changes and returns to its original position, thereby moving the limiting block 25 into the limiting groove 27 to complete the locking operation. This ensures the reliability of the fixation and makes disassembly very convenient. The inclined surface design of the limiting block 25 makes it easier to insert the limiting block 25 into the slot 26 without the need for manual fine-tuning. The limiting block 25 can be inserted into the slot 26 simply by following its inclined surface.

[0025] Example 2

[0026] like Figure 1 , 4 As shown in Figure 5, the multi-level buffer structure 3 includes several micro springs 31, which are fixedly installed on the inner sides of the two first frames 21 and the two second frames 23 respectively. A buffer pad 32 is fixedly installed at one end of each micro spring 31. Rubber connecting layers 34 are fixedly installed on both sides of the inner sides of the two first frames 21 and the two second frames 23. A flexible contact layer 35 is fixedly installed on one side of each of the two rubber connecting layers 34. Several energy-absorbing blocks 33 are fixedly installed between the two first frames 21 and the two second frames 23 and the four buffer pads 32 respectively. The cross-section of the energy-absorbing blocks 33 is designed in a honeycomb structure.

[0027] In this embodiment, the plurality of miniature springs 31 are preferably conical helical springs made of stainless steel. They are arranged in a certain array in the reserved cavities inside the first frame 21 and the second frame 23. The energy-absorbing blocks 33 are filled between the plurality of miniature springs 31. The energy-absorbing blocks 33 are made of closed-cell aluminum foam with a porosity of 70% to 80% or polymer materials with high energy absorption efficiency. When impacted, the miniature springs 31 first undergo elastic deformation to absorb part of the energy. Then, the energy-absorbing blocks 33 further dissipate energy through their own plastic deformation or pore compression, thereby achieving multi-level buffering to effectively protect the touch screen device body 11, reduce the force generated when the touch screen device body 11 is impacted, and avoid damage to the touch screen device body 11. The flexible contact layer 35 is made of liquid silicone and combined with the first frame 21 and the second frame 23 to ensure seamlessness and non-detachment, achieving a balance between soft contact and structural strength.

[0028] Working principle:

[0029] like Figure 1-5As shown, during use, the two second frames 23 are respectively clipped onto the upper and lower sides of the touch screen device body 11. The second frames 23 on the upper and lower sides of one of the first frames 21 are aligned with one side of the two second frames 23. Then, the limiting block 25 is inserted into the slot 26. When the limiting block 25 is inserted to the bottom of the slot 26, the elastic piece 24 will undergo elastic deformation to drive the limiting block 25 to move into the limiting groove 27, thereby fixing the two second frames 23 to one of the first frames 21. Then, the other first frame 21 is connected to the other side of the two second frames 23 to complete the installation. When disassembling, simply press the limiting block 25 through the limiting groove 27 to release the limiting of the second frame 23 and the connecting frame 22. The operation is simple and convenient. The non-enclosed design can effectively protect the touch screen device body 11 and reduce contact with the touch screen device body 11, ensuring that the heat dissipation of the touch screen device body 11 is not affected, thus improving the practicality of the structure.

[0030] When the touch screen device body 11 is impacted, the edge of the touch screen device body 11 will contact the buffer pad 32 on the inner side of the first frame 21 and the second frame 23 for initial buffering. Then, through the elastic deformation of several micro springs 31, some energy is absorbed to complete the secondary buffering. Finally, through the plastic deformation of several energy-absorbing blocks 33, the pores are compressed to further dissipate energy, thereby completing the multi-stage buffering operation. This effectively reduces the impact force when the touch screen device body 11 is impacted, avoids damage to the edge of the touch screen device body 11 due to excessive impact force, and improves the performance of the structure.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
