Description

Technical Field

[0001] This utility model relates to the field of touch panel light shielding technology, and in particular to a light shielding unit for a touch panel. Background Technology

[0002] Touchpad shading issues typically refer to situations where the touchpad becomes inaccurate or unusable due to ambient light. Applying a light-shielding film to the surface or internal components of the touchpad can achieve the shading effect by reflecting and absorbing light.

[0003] The above-mentioned and existing technologies have the following drawbacks: In the actual disassembly process of the light-shielding plate, due to the high adhesiveness of the adhesive layer, the surface of the light-shielding plate will be damaged when other instruments are used to disassemble the light-shielding plate, resulting in changes in the performance of the light-shielding plate.

[0004] Therefore, a light-shielding unit for a touchpad is proposed. Utility Model Content

[0005] The purpose of this invention is to address the drawback that the surface of the light shield is damaged when it is disassembled using other instruments due to the high adhesiveness of the adhesive layer, which leads to changes in the performance of the light shield. Therefore, a light shielding unit for a touch panel is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a light-shielding unit for a touch panel, comprising a light-emitting plate, an adhesive layer mounted on the surface of the light-emitting plate, a light-shielding plate mounted on the surface of the adhesive layer, a light-transmitting hole on the surface of the light-shielding plate, and a convenient device on the surface of the light-shielding plate, the convenient device comprising a groove, the groove being formed on the surface of the light-shielding plate, two limiting grooves being formed on the surface of the groove, a slider being slidably connected to the surface of each of the two limiting grooves, a limiting strip being fixedly connected to the surface of the slider, a pull strap being fixedly connected to the surface of the limiting strip, the pull strap being slidably connected to the groove, and a frosted layer being formed on the surface of the pull strap, the frosted layer being slidably connected to the groove.

[0007] The effect achieved by the above-mentioned components is as follows: by setting up a convenient device, the light shield can be easily separated from the adhesive layer on the light-emitting plate by utilizing the cooperation between the groove, limiting groove, sliding strip, limiting strip, pull strap and frosted layer. This avoids damage to the surface of the light shield caused by the high adhesiveness of the adhesive layer when using other tools to disassemble the light shield, which would lead to changes in the performance of the light shield. This improves the convenience of disassembling the light shield and further enhances the protective effect of the light shield.

[0008] Preferably, an auxiliary belt, which is a rubber belt, is fixedly connected to the surface of the pull belt.

[0009] The effect achieved by the above components is as follows: when the pull strap is pulled away from the sunshade, the pull strap will drive the auxiliary strap to move. At this time, the rubber auxiliary strap can increase the friction between the fingers and the pull strap.

[0010] Preferably, the surface of the auxiliary belt is provided with a plurality of protrusions, and the plurality of protrusions are evenly distributed on the surface of the auxiliary belt.

[0011] The effect achieved by the above components is that when you press your finger against the protrusions on the auxiliary strap, the protrusions increase the friction between your finger and the auxiliary strap.

[0012] Preferably, the surface of the groove has rounded corners.

[0013] The effect achieved by the above components is that the pull strap will slide out from the rounded corner of the groove, at which point the rounded corner allows the pull strap to slide out of the groove easily.

[0014] Preferably, the surface of the slide bar is rotatably connected with a ball bearing, and the ball bearing is slidably connected to the limiting groove.

[0015] The effect achieved by the above components is that the slider will drive the ball to slide along the surface of the limiting groove, and at this time the ball can reduce the friction between the slider and the limiting groove.

[0016] Preferably, the surface of the pull strap is fixedly connected with three pointed cones, and the cross-section of each of the three pointed cones is triangular.

[0017] The effect achieved by the above components is that the pull strap will cause the pointed cone to detach from the light shield, at which point the pointed cone can limit the position of the pull strap in the groove.

[0018] Preferably, the surface of the pointed cone is fixedly connected with barbs.

[0019] The effect achieved by the above components is that the pointed cone will cause the barbs to detach from the light shield, and at this time the barbs can increase the friction between the pointed cone and the light shield.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, by setting up a convenient device, the light shield can be easily detached from the adhesive layer on the light-emitting plate by utilizing the cooperation between the groove, the limiting groove, the sliding strip, the limiting strip, the pull strap and the frosted layer. This avoids the damage to the surface of the light shield caused by the high adhesiveness of the adhesive layer when using other instruments to disassemble the light shield, which would lead to changes in the performance of the light shield. This improves the convenience of disassembling the light shield and further enhances the protective effect of the light shield. Attached Figure Description

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] like Figures 1-5 As shown, this utility model provides a light-shielding unit for a touch panel, including a light-emitting plate 1, an adhesive layer 2 installed on the surface of the light-emitting plate 1, a light-shielding plate 3 installed on the surface of the adhesive layer 2, a light-transmitting hole 4 opened on the surface of the light-shielding plate 3, and a convenient device 5 provided on the surface of the light-shielding plate 3.

[0031] The following section will explain the specific design and function of its convenient device 5.

[0032] like Figures 2-5As shown, the convenient device 5 includes a groove 501, which is formed on the surface of the light-shielding plate 3. Two limiting grooves 502 are formed on the surface of the groove 501. Sliding strips 503 are slidably connected to the surfaces of both limiting grooves 502. Limiting strips 504 are fixedly connected to the surfaces of the sliding strips 503. A pull strap 505 is fixedly connected to the surface of the limiting strips 504. The pull strap 505 is slidably connected to the groove 501. A frosted layer 506 is provided on the surface of the pull strap 505, and the frosted layer 506 is slidably connected to the groove 501. An auxiliary strap 507, made of rubber, is fixedly connected to the surface of the light-shielding plate 3. Pulling the strap 505 away from the light-shielding plate 3 causes the auxiliary strap 507 to move. The rubber material of the auxiliary strap 507 increases the friction between the finger and the strap 505. The surface of the auxiliary strap 507 has several raised dots 508 evenly distributed. Pressing a finger against the raised dots 508 causes them to... To increase the friction between the finger and the auxiliary strap 507, the surface of the groove 501 is provided with a rounded corner 509. The pull strap 505 will slide out from the rounded corner 509 on the groove 501. At this time, the rounded corner 509 facilitates the pull strap 505 to slide out of the groove 501. A ball bearing 510 is rotatably connected to the surface of the slide bar 503. The ball bearing 510 is slidably connected to the limiting groove 502. The slide bar 503 will drive the ball bearing 510 to slide along the surface of the limiting groove 502. At this time, the ball bearing 510 can reduce the friction between the slide bar 503 and the limiting groove 502. The friction between the grooves 502 is due to the fact that the surface of the pull strap 505 is fixedly connected to three pointed cones 511, the cross-section of which is triangular. The pull strap 505 will cause the pointed cones 511 to separate from the light shield 3. At this time, the pointed cones 511 can limit the position of the pull strap 505 in the groove 501. The surface of the pointed cones 511 is fixedly connected to barbs 512. The pointed cones 511 will cause the barbs 512 to separate from the light shield 3. At this time, the barbs 512 can increase the friction between the pointed cones 511 and the light shield 3.

[0033] The overall working principle is as follows: when it is necessary to separate the light-shielding plate 3 from the adhesive layer 2 on the light-emitting plate 1, you can press the protrusion 508 on the auxiliary tape 507 with your finger and then pull the tape 505 away from the light-shielding plate 3. At this time, the protrusion 508 can increase the friction between the finger and the auxiliary tape 507. At the same time, the rubber auxiliary tape 507 can increase the friction between the finger and the tape 505. Then the tape 505 will drive the limiting strip 504 along the surface of the groove 501 along the surface of the limiting groove 502. As the belt slides, the pull belt 505 drives the slide bar 503 to slide along the surface of the limiting groove 502. Then, the slide bar 503 drives the ball bearing 510 to slide along the surface of the limiting groove 502. At this time, the ball bearing 510 reduces the friction between the slide bar 503 and the limiting groove 502. Then, the pull belt 505 drives the frosted layer 506 to slide along the surface of the groove 501. Simultaneously, the pull belt 505 slides out from the rounded corner 509 on the groove 501. The rounded corner 509 facilitates the pull belt 505's exit from the groove. The pull strap 505 slides out of the groove 501, and then the pull strap 505 will cause the pointed cone 511 to disengage from the light shield 3. At this time, the pointed cone 511 can limit the position of the pull strap 505 in the groove 501. At the same time, the pointed cone 511 will cause the barb 512 to disengage from the light shield 3. At this time, the barb 512 can increase the friction between the pointed cone 511 and the light shield 3. Then, when the limiting strip 504 abuts against the limiting groove 502, the pull strap 505 can be pulled upward. At this time, the pull strap 505 will cause the light shield 3 to detach from the adhesive layer 2 on the light-emitting plate 1. By setting up a convenient device 5, the light shield 3 can be easily detached from the adhesive layer 2 on the light-emitting plate 1 through the cooperation between the groove 501, the limiting groove 502, the sliding strip 503, the limiting strip 504, the pull strap 505, and the frosted layer 506. This avoids damage to the surface of the light shield 3 caused by the high stickiness of the adhesive layer 2 when using other tools to disassemble the light shield 3, which would lead to changes in the performance of the light shield 3. This improves the convenience of disassembling the light shield 3 and further enhances the protective effect of the light shield 3.

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.
