Technical Field
[0001] The utility model relates to the technical field of mobile phone button protective covers, and particularly relates to a touch-sensitive mobile phone button protective cover. Background Art
[0002] A mobile phone case is an ornament for protecting or decorating the appearance of a mobile phone.
[0003] With the rapid development of the technology level, the industry of technology beauty emerges as a new industry. Fashionable IT brands develop diversely along with the diversified development of the market. With the increase in mobile phone brands and functions, mobile phone cases are diversified according to texture, including PC cases, leather, silicone, fabric, hard plastic, leather cases, metal tempered glass cases, soft plastic, flannelette, silk, etc. Mobile phone cases not only make your mobile phone a scenery as an ornament, but also can protect the mobile phone from being dropped, scratched, watered and shocked.
[0004] Existing mobile phone cases generally cover the side buttons of the mobile phone. However, with the replacement of mobile phones, more and more side buttons of mobile phones adopt capacitive touch buttons to realize interaction with the mobile phone through touch. The material of the existing mobile phone cases in the contact part with the mobile phone buttons is the same as that of the mobile phone cases, which will prevent users from interacting with the capacitive touch buttons. Content of the Utility Model
[0005] Aiming at the deficiencies of the prior art, the utility model provides a touch-sensitive mobile phone button protective cover, which has the advantages of protecting the buttons and triggering the touch buttons at the same time, and solves the problem that the existing mobile phone cases cannot trigger the touch buttons.
[0006] The purpose of the utility model is achieved through the following technical solutions:
[0007] A touch-sensitive mobile phone button protective case, comprising a mobile phone body and a button protective case. A touch button is provided on the mobile phone body. The touch button can use the capacitance of the human body as a signal source. When the human body contacts the touch button, the mobile phone body can be triggered to perform a preset behavior. The button protective case completely covers the touch button, isolating the touch button from the outside world, protecting the touch button, and preventing the touch button from being scratched, liquid-entering, etc., effectively extending the service life of the touch button. A touch layer for human contact is provided on the top surface of the button protective case. The touch layer is attached to the top surface of the touch button. When the touch layer contacts the human body, a capacitance signal source that can be recognized by the touch button can be formed with the human body. When the touch button receives the signal source, the mobile phone body can perform a preset behavior. While protecting the touch button, the functionality of the touch button is not damaged, and the user can still normally operate the touch button through the button protective case. The button protective case is also provided with a positioning member, which can assist each component to be accurately formed and installed during production. An opening is provided in the middle of the positioning member, and an insulating sleeve is wrapped outside the positioning member, effectively isolating the capacitance signal generated when the human body contacts other places outside the touch layer from being recognized by the touch button, preventing accidental touch. The middle of the insulating sleeve is hollowed out to form a placement groove one for placing the touch layer. The touch layer is divided into an insulating layer and a conductive layer, and the insulating layer is located on the conductive layer.
[0008] In one embodiment, the positioning member is provided with a positioning ring body, which can provide a supporting force for the insulating sleeve wrapped outside it, so that the insulating sleeve will not deform when the user touches and presses. Positioning wings are provided at the front and rear ends of the positioning ring body, which are convenient for the device to calibrate the positioning member. A convex ring one extending outward is provided at the bottom of the positioning ring body. The bottom surface of the convex ring one is flat, which can prevent the bottom of the positioning ring body from cutting the insulating sleeve when the user presses the button protective case. The connection between the convex ring one and the positioning ring body adopts a smooth transition and has no angular design to avoid cutting the insulating sleeve. The cross section of the convex ring one and the positioning ring body is in an L shape. A fixing member for fixing the conductive layer is also provided in the placement groove one.
[0009] In one embodiment, the fixing member is a convex ring two extending from the middle of the inner wall of the placement groove one. The space surrounded by the convex ring two forms a placement groove two, and the conductive layer is placed in the placement groove two. The placement groove two can limit the movement direction of the conductive layer.
[0010] In one embodiment, a groove is provided on the back surface of the convex ring two, making the thickness of the connection between the convex ring two and the placement groove one thinner, making the convex ring two easier to deform, that is, the touch layer is easier to be pressed. The shape of the placement groove two is a geometric reduction of the shape of the placement groove one.
[0011] In one of the embodiments, the size of the insulating layer is a proportional reduction of the shape of the placement groove one, that is, a gap is provided between the outer wall of the insulating layer and the inner wall of the placement groove one, that is, the insulating layer and the insulating sleeve are not directly connected, and the insulating layer can be pressed more easily. The size of the conductive layer is the same as the shape of the placement groove two, and the two can fit better. The cross-section of the insulating layer and the conductive layer after being fitted together is T-shaped, which effectively reduces the weight of the conductive layer and makes the weight of the key protection cover lower. The side wall of the conductive layer is fixedly connected to the inner wall of the placement groove two, and the two are not easy to separate.
[0012] In one of the embodiments, the insulating layer is made of glass, and the conductive layer is made of metallic copper. Copper is a soft metal, easier to process and shape, and has good conductivity. The insulating layer is a glass sheet, the conductive layer is a copper sheet, and the insulating sleeve is made of silicone, so that the convex ring 2 has a better reset ability. When the user is not pressing the touch layer, the convex ring 2 can carry the copper sheet and the glass sheet to reset.
[0013] In one of the embodiments, the outer wall of the insulating sleeve is also connected to a mobile phone cover, and when the mobile phone cover is put on the mobile phone body, the key protection cover is just put on the touch key.
[0014] Beneficial Effects
[0015] The key protection cover can completely cover the touch key to isolate it from the outside world, effectively prolonging the life of the touch key. A touch layer is provided. When the user's fingertips touch the touch layer, the touch key 3 can be triggered, and the mobile phone body 1 can perform a preset operation. While protecting the touch key, the function of the touch key will not be impaired. A positioning piece is provided. During processing, the positioning piece has a positioning effect, which is convenient for making the key protection cover. When in use, the positioning ring in the positioning piece can play a supporting role. When the customer presses the key protection cover, the downward pressure is evenly distributed to the touch key, so that the force is evenly applied. It has the advantages of good protection effect, simple and quick installation, and good triggering effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment
[0036] As Figures 1 to 12, A sensitive mobile phone button protective case, including a mobile phone body 1 and a button protective case 2. There is a touch button 3 on the mobile phone body 1. The touch button 3 can use the capacitance of the human body as a signal source. When the human body contacts the touch button 3, it can trigger the mobile phone body 1 to perform a preset behavior. The specific principle is that when the user's finger touches the insulating layer on the touch button 3, since the finger has conductivity, a capacitor will be formed between the finger and the conductive layer through the insulating layer. The existence of this capacitor will cause the charge distribution on the conductive layer to change, thereby changing the original electric field distribution. The circuit inside the touch button 3 will detect this change in capacitance value and convert it into an electrical signal for processing. The mobile phone body 1 can perform corresponding operations according to the signal fed back by the touch button 3. For example, when the touch button 3 of iPhone 16 is touched, it will trigger the camera shooting effect, and the touch button 3 can be regarded as a shutter button. The button protective case 2 can completely cover the touch button 3, isolating the touch button 3 from the outside world and forming protection for the touch button 3. There is a touch layer 4 for human contact on the top surface of the button protective case 2. The touch layer 4 is attached to the top surface of the touch button 3. When the touch layer 4 contacts the human body, it can form a capacitance signal source that can be recognized by the touch button 3. When the touch button 3 receives the signal source, it can make the mobile phone body 1 perform a preset behavior. When in use, just correctly put the mobile phone case with the button protective case 2 on the mobile phone body 1, then the button protective case 2 will also cover the touch button 3. When it is necessary to touch the touch button 3, simply touch the touch layer 4 directly to complete the interaction with the touch button 3. The button protective case 2 is also provided with a positioning member 5. There is a slot 6 in the middle of the positioning member 5. The positioning member 5 is covered with an insulating sleeve 7. The middle of the insulating sleeve 7 is hollowed out to form a placement groove 8 for placing the touch layer 4. The touch layer 4 is divided into an insulating layer 9 and a conductive layer 10. The insulating layer 9 is located on the conductive layer 10.
[0037] Preferably, the positioning member 5 is provided with a positioning ring body 11. There are positioning wings 12 at the front and rear ends of the positioning ring body 11. There is an outwardly extending convex ring 13 at the bottom of the positioning ring body 11. The bottom surface of the convex ring 13 is flat. The connection between the convex ring 13 and the positioning ring body 11 is smoothly transitioned. The cross-section of the convex ring 13 and the positioning ring body 11 is in an L shape. There is also a fixing member for fixing the conductive layer 10 in the placement groove 8.
[0038] By adopting the above technical solution, during production, the positioning member 5 is placed in the mold, and silicone is poured in. After the silicone solidifies, the insulating sleeve 7 is formed and exactly completely wraps the positioning member 5. At this time, the touch layer 4 can be installed in the placement groove 8. When pressing the touch layer 4, the convex ring 13 can evenly distribute the pressure at its bottom, preventing the bottom of the positioning ring body 11 from cutting the insulating sleeve 7.
[0039] Preferably, the fixing member is a second convex ring 14 extending from the middle of the inner wall of the first placing groove 8. The space surrounded by the second convex ring 14 forms a second placing groove 15, and the conductive layer 10 is placed in the second placing groove 15.
[0040] By adopting the above technical solution, the second convex ring 14 is used to limit the moving direction of the touch layer 4. At the same time, the second convex ring 14 has the ability to reset. When the user stops pressing the touch layer 4, the second convex ring 14 can carry the touch layer 4 to reset together.
[0041] Preferably, a groove 16 is provided on the back surface of the second convex ring 14, so that the thickness of the connection between the second convex ring 14 and the first placing groove 8 becomes thinner. The shape of the second placing groove 15 is a scaled-down shape of the first placing groove 8.
[0042] By adopting the above technical solution, when pressing the touch layer 4, since the groove 16 makes the thickness of the connection between the second convex ring 14 and the first placing groove 8 thinner, the touch layer 4 is more easily pressed down, and the groove 16 also becomes the space for the second convex ring 14 to deform during the downward pressing process.
[0043] Preferably, the size of the insulating layer 9 is a scaled-down shape of the first placing groove 8, that is, there is a gap between the outer wall of the insulating layer 9 and the inner wall of the first placing groove 8. The size of the conductive layer 10 is the same as the shape of the second placing groove 15. The cross-section of the insulating layer 9 and the conductive layer 10 after fitting is in a T shape, and the side wall of the conductive layer 10 is fixedly connected to the inner wall of the second placing groove 15.
[0044] By adopting the above technical solution, the insulating layer 9 is not directly connected to the insulating sleeve 7. When pressing the touch layer 4, the insulating layer 9 is not affected by the insulating sleeve 7. Only the second convex ring 14 generates resistance, making the touch layer 4 more easily pressed down. When no longer affected by the downward pressure of the user's fingertip, the second convex ring 14 can carry the touch layer 4 to reset. Specifically, the second convex ring 14 carries the conductive layer 10 to reset, and the conductive layer 10 is attached to the insulating layer 9. Because the insulating layer 9 also resets, the insulating layer 9 and the conductive layer 10 can be attached by glue. The glue forms a glue ring along the right-angle area formed at the connection surface of the two to attach the two, and the second convex ring 14 and the conductive layer 10 are also attached by glue.
[0045] Preferably, the material of the insulating layer 9 is glass, the material of the conductive layer 10 is copper, the insulating layer 9 is a glass sheet, the conductive layer 10 is a copper sheet, and the material of the insulating sleeve 7 is silicone.
[0046] By adopting the above technical solution, glass is an inorganic non-metallic material with good insulation properties, so it is suitable as the insulation layer 9. Copper is a soft metal, which is easier to process and has good conductivity, so it is suitable as the conductive layer 10. Silicone has excellent electrical insulation properties and good flexibility, and has a reset effect, so that the insulating sleeve 7 can not only insulate, but also assist in resetting the touch layer 4.
[0047] Preferably, the outer wall of the insulating sleeve 7 is also connected to a mobile phone sleeve.
[0048] By adopting the above technical solution, the insulating sleeve 7 is connected to the mobile phone case and is arranged on the side wall of the mobile phone case. The mobile phone case can also be made of silicone material, that is, the mobile phone case can be formed at the same time as the insulating sleeve 7. After the mobile phone case is put on the mobile phone body 1, while protecting the mobile phone, it can also interact with the touch button 3 through the key protection cover 2.
[0049] Working principle: Put the mobile phone case on the mobile phone body 1 so that the button protection cover 2 can completely cover the touch button 3, so that the touch button 3 is isolated from the outside world, thereby protecting the touch button 3. A touch layer 4 for human contact is provided on the top surface of the button protection cover 2. The touch layer 4 is in contact with the top surface of the touch button 3. When the user touches the touch layer 4 with a finger, the human body and the touch layer 4 form a capacitive signal source that can be recognized by the touch button 3. When the touch button 3 receives the signal source, the mobile phone body 1 can perform a preset behavior.
[0050] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
