Description

[0001] This application claims priority to Chinese Patent Application No. 202520190448.8, filed on February 6, 2025, with the Chinese Patent Office, entitled "A Button Structure and Electronic Device Accessory", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the technical field of accessories for electronic devices, and particularly to a button structure and electronic device accessories. Background Technology

[0003] Currently, smartphones and other electronic devices are typically controlled via touchscreens. Touchscreen operation requires unlocking the screen, which involves several steps. To make certain operations more convenient for users, such as adjusting volume and turning the phone on or off, mechanical buttons are usually located on the side of the phone for users to press and control the corresponding functions. Compared to unlocking the screen first, users can press the mechanical buttons to operate the corresponding functions with a single click, which is more efficient and faster. For users using protective cases, case manufacturers also include buttons on the cases that can move along the thickness of the case. These buttons correspond to the mechanical buttons on the phone, allowing users to press the button on the case to trigger and control the phone.

[0004] With the continuous development of technology, mobile phone buttons have integrated more and more functions. In addition to pressing operations, touch operations have also been integrated into the buttons. This makes the button structure on existing protective cases no longer suitable for mobile phone buttons.

[0005] Therefore, it is necessary to improve the existing button structure to solve the above problems. Utility Model Content

[0006] This application discloses a button structure, including:

[0007] The device includes a main body, a conductive component, and a deformable component. The main body includes a top surface and a bottom surface. The main body has a through hole that extends through the main body along its thickness direction. The conductive component includes a first conductive part, a second conductive part, and a third conductive part. The first conductive part is located on the top surface, the second conductive part is located in the through hole, and the third conductive part is located on the bottom surface. The deformable component is connected to one side of the bottom surface and covers the third conductive part.

[0008] Compared with the prior art, this application has at least the following beneficial effects:

[0009] The button structure provided by this utility model includes a main body, a conductive component, and a deformable component. The main body includes a top surface and a bottom surface, wherein the top surface is for user operation, and the bottom surface is the surface that contacts the touch button of the electronic device. By providing a through hole in the main body, the conductive component can electrically connect the top and bottom surfaces. A first conductive part is provided on the top surface, and a third conductive part is provided on the bottom surface. Compared with the prior art where the conductive part is only provided in the through hole, the provision of the first and third conductive parts increases the contact area between the conductive component and the user's finger and the touch button of the electronic device, thereby effectively improving the sensitivity of electrical signal transmission. The button structure can more accurately and quickly transmit the user's operation commands to the touch button of the electronic device, enabling the electronic device to respond to the corresponding function. Simultaneously, the deformable component covers the third conductive part, protecting it from direct contact with the touch button of the phone, preventing scratches, and isolating it from the air, preventing oxidation and reduced conductivity.

[0035] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0036] See Figures 1-3 This application provides a button structure that can be used on electronic device accessories, such as protective cases. These protective cases are used to cover and protect electronic devices, such as mobile phones and tablets. The button structure corresponds to the touch button settings of the electronic device. The button structure includes a main body 1, a conductive member 2, and a deformable member 3. The main body includes a top surface 1a and a bottom surface 1b. The main body 1 has a through hole 11 extending through the body along its thickness direction. The conductive member 2 includes a first conductive part 21, a second conductive part 22, and a third conductive part 23. The first conductive part 21 is located on the top surface 1a, the second conductive part 22 is located within the through hole, and the third conductive part is located on the bottom surface 1b. The deformable member 3 is connected to one side of the bottom surface 1b of the main body 1.

[0037] Let's take a protective case as an example. Figure 17As shown, when the above-mentioned button structure is installed on the protective shell, the protective shell is fitted onto the electronic device so that the button structure corresponds to the position of the touch button on the electronic device. When the user touches the top surface 1a, the microcurrent on the user's finger is transmitted to the second conductive part 22 through the first conductive part 21, and then to the third conductive part 23 through the second conductive part 22. Since the third conductive part 23 is in contact with the touch button on the electronic device, the microcurrent is transmitted to the touch button through the third conductive part 23. After the sensor inside the touch button receives the microcurrent signal, it will respond to the signal and operate the electronic device to trigger the corresponding function. By setting the first conductive part 21 and the third conductive part 23, the contact area between the user's finger and the conductive part 2, as well as the contact area between the conductive part 2 and the touch button of the electronic device, is effectively increased, improving the sensitivity of signal transmission when the user performs touch operation and the sensitivity of the touch button of the electronic device to signal reception, thus optimizing the user experience. Meanwhile, the third conductive part 23 is covered by the deformable part 3, which can protect the third conductive part 23. On the one hand, it prevents it from directly contacting the touch button of the mobile phone and scratching the touch button of the mobile phone. On the other hand, it can isolate the third conductive part 23 from the air and prevent its conductivity from decreasing after oxidation.

[0038] In some embodiments, see Figure 4 The main body also includes a side surface 1c located between the top surface 1a and the bottom surface 1b. The side surface 1c has a first protrusion 12. The deformable component 3 includes a first part 31 and a second part 32. The first part 31 is connected to one side of the bottom surface 1b of the main body 1, and the second part 32 extends away from the side surface 1c, so that a groove 13 is formed between the first protrusion 12 and the second part 32. The button structure is connected to the protective shell through the groove 13. Specifically, as shown... Figure 17 As shown, a through hole 51 can be made in the protective shell 5. The button structure is installed in the through hole 51 and is engaged with the side wall of the through hole 51 by the slot 13. See reference. Figure 18 When the button structure is installed on the protective case, the second part 32 abuts against the side wall of the through hole on the protective case. Since the second part 32 is made of a soft material, it has a certain degree of elasticity and deformation capability. Therefore, the abutment will make the first part 31 of the button structure closely adhere to the surface of the phone's touch button, that is, the first part 31 is always in contact with the phone's touch button. When using the phone, the user only needs to touch the main body 1 with their finger to make electrical contact between the finger and the touch button to operate the phone. It is not necessary to press the main body 1 to make the first part 31 contact the touch button.

[0039] In some embodiments, the first protrusion 12 is an annular structure, circumferentially arranged on the side 1c of the main body. The second part 32 is also an annular structure, circumferentially arranged on the side 1c of the main body. The annular structure ensures that the slot 13 is circular overall, resulting in a more secure connection between the button structure and the protective shell, preventing detachment. In other embodiments, the first protrusion 12 may not be a single annular structure, but rather multiple protrusions arranged circumferentially on the main body 1. Similarly, multiple second parts 32 are also arranged circumferentially on the main body 1. This arrangement also ensures a stable connection between the button structure and the protective shell, preventing the button structure from detaching during use.

[0040] In some embodiments, see Figure 4 and Figure 5 The first part 31 includes a main body 311 and a surrounding part 312 protruding from the main body 311. The main body 311 and the surrounding part 312 together form a mounting groove 313. A part of the main body 1 is installed in the mounting groove 313, and the surrounding part 312 surrounds the side 1c of the main body 1. The first part 31 can be made of a flexible material such as silicone, which has a certain degree of deformation and elasticity. The first part 31 is integrally formed with the main body 1 through processes such as injection molding to enclose a part of the main body 1. The surrounding part 312 increases the connection area between the main body 1 and the first part 31, making them less likely to separate after integral molding and ensuring a strong connection. In other embodiments, the first part 31 and the main body 1 can also be connected without injection molding, for example, by adhesive, snap-fit, or other methods. Since the third conductive part 23 is located on the bottom surface 1b of the main body 1, when the first part 31 is connected to the main body 1, it also covers the third conductive part 23. That is, the third conductive part 23 is located between the main body 1 and the first part 31. The first part 31 can protect the third conductive part 23, preventing it from directly contacting the touch button of the mobile phone and scratching it. On the other hand, it can isolate the third conductive part 23 from the air, preventing its conductivity from decreasing after oxidation. Furthermore, when the button structure contacts the touch button of the mobile phone, a capacitor structure is formed between the third conductive part 23, the first part 31, and the touch button of the mobile phone. The third conductive part 23 and the touch button of the mobile phone act as two conductors close to each other, while the first part 31 is a non-conductive insulating medium sandwiched between them. The formation of the capacitor structure allows the microcurrent of the human body to still be conducted to the touch buttons of the mobile phone. However, when the thickness of the first part 31 is too thick, for example, greater than 0.5mm, the transmission of electrical signals will be unstable, which will cause problems such as unresponsive touch operation and slow mobile phone response. Therefore, the thickness of the first part 31 should be less than or equal to 0.5mm to ensure stable transmission of electrical signals.

[0041] In some embodiments, see Figure 13 and Figure 14 In the embodiment shown in the figure, the perimeter portion 312 and the second portion 32 are spaced apart, and a portion of the slot 13 is formed between them. From the overall structure, the arrangement of the main body portion 311, the perimeter portion 312, and the second portion 32 is more compact, which can reduce the thickness of the deformable part 3 to a certain extent. In other embodiments, such as Figure 4 and Figure 5 As shown, the second part 32 and the surrounding part 312 are not spaced apart, but are connected to the end of the surrounding part 312 away from the main part 311.

[0042] In some embodiments, see Figures 4-6 The deformable component 3 also includes a third part 33, which protrudes from the bottom of the mounting groove 313. A recessed portion 14 is recessed on the bottom surface 1b of the main body 1, communicating with the through hole 11. The third part 33 is inserted into the recessed portion 14. Typically, the main body 1 is made of a rigid material, while the deformable component 3 is usually made of a soft material, making it relatively lightweight. Through a nested connection, the connection strength between the deformable component 3 and the main body 1 can be enhanced, and the overall weight of the button structure can be reduced to some extent. In other embodiments, such as... Figure 13 As shown, instead of providing a recessed portion 14 on the bottom surface 1b of the main body 1, the third portion 33 can be inserted into the through hole 11, and the second conductive portion 22 can cover the inner wall of the through hole 11. In this way, the third portion 33 can cover the second conductive portion 22, effectively isolating the second conductive portion from the air and preventing the second conductive portion 22 from oxidizing and affecting its conductivity.

[0043] In some embodiments, see Figure 7 and Figure 12 The area of ​​the opening of the through hole 11 on the top surface 1a of the main body 1 is smaller than the area of ​​the opening of the through hole 11 on one side of the bottom surface 1b. The opening on the bottom surface 1b can be on the bottom surface 1b or on the bottom of the recess 14. In this embodiment, the second conductive part 22 is attached to the sidewall of the through hole 11 using laser engraving technology. By making the opening on the bottom surface 1b wider, the laser engraving machine can complete the laser engraving in one go from the opening on the bottom surface 1b without having to flip the main body 1 over midway. If the openings on the top surface 1a and the bottom surface 1b are the same size, the laser engraving machine can only engrave half the depth of the through hole 11 from the opening on one side; the other half requires flipping the main body 1 over before laser engraving. Further, see [link to documentation]. Figure 12Along the direction from the top surface 1a to the bottom surface 1b, that is, along the thickness direction of the main body 1, the cross-sectional area of ​​the through hole 11 gradually increases. Here, "cross-section" refers to the surface formed by cutting the main body 1 along a direction perpendicular to its thickness. Alternatively, it can be understood that the diameter of the through hole 11 gradually increases along the direction from the top surface 1a to the bottom surface 1b. This design is more conducive to laser engraving machine processing and can effectively improve production efficiency.

[0044] In some embodiments, see Figure 11 , Figure 12 and Figure 15 The through holes 11 include multiple (two or more) arranged at intervals along the length of the main body 1, with adjacent through holes 11 staggered. That is, along the width of the main body 1, one of adjacent through holes 11 is closer to the left side of the main body 1, and the other is closer to the right side of the main body 1. Compared to Figure 2 As shown in the embodiment, multiple through holes 11 are arranged in a straight line along the length of the main body 1. The through holes 11 are staggered, which on the one hand increases the distance between two adjacent through holes 11, that is, increases the thickness of the hole wall, and correspondingly improves the strength of the hole wall; on the other hand, by increasing the distance between two adjacent through holes 11, the distance between the second conductive parts 22 attached to the inner wall of the through hole 11 can be effectively increased. When the user performs a touch operation and current flows through the second conductive parts 22, the electromagnetic interference between two adjacent second conductive parts 22 can be effectively reduced, and the stability of the touch operation can be improved.

[0045] In some embodiments, see Figure 2 and Figure 12 The first conductive part 21 includes multiple (two or more) components, which are spaced apart and insulated from each other along the length of the main body 1. Each first conductive part 21 covers the area surrounding the opening of the through hole 11 on the top surface and extends along the width of the main body 1. By covering the area surrounding the opening of the through hole 11 on the top surface 1a with the first conductive part 21, the connection area between the first conductive part 21 and the second conductive part 22 is increased, ensuring a stable electrical connection between them. Simultaneously, the first conductive part 21 extends along the width of the main body 1, covering as much of the top surface 1a as possible. When the user performs a touch operation, signal transmission can be achieved as long as any area of ​​the top surface 1a is touched, effectively improving the user experience.

[0046] For further information, please refer to [link / reference]. Figure 15In some embodiments, the third conductive part 23 may include multiple (two or more) such parts. These multiple third conductive parts 23 are spaced apart along the length of the main body 1 and insulated from each other. Each third conductive part 23 covers the area surrounding the opening of the through hole 11 on one side of the bottom surface 1b and extends along the width of the main body 1. Similar to the arrangement of the first conductive part 21, by covering the area surrounding the opening of the through hole 11 on the bottom surface 1b with the third conductive part 23, the connection area between the third conductive part 23 and the second conductive part 22 can be increased, ensuring a stable electrical connection between them. Simultaneously, the extension of the third conductive part 23 along the width of the main body 1 further increases the contact area between the third conductive part 23 and the touch buttons of the mobile phone, ensuring stable signal transmission.

[0047] In some embodiments, see Figure 2 , Figure 12 and Figure 15 In some embodiments, the second conductive portion 22 may include multiple portions (two or more), with one second conductive portion 22 covering the inner wall of each through hole 11. By setting the second conductive portion 22 as a conductive layer covering the inner wall of the through hole 11, it is easier to manufacture, as it can be achieved using existing mature laser engraving technology. Furthermore, compared to inserting conductive posts into the through hole 11, the conductive layer design can effectively reduce the amount of conductive material used, lowering costs. Moreover, the conductive layer can stably adhere to the inner wall of the through hole 11 without the risk of detachment, resulting in higher product reliability.

[0048] Furthermore, in some embodiments, the surface of the first conductive part 21 is flush with the top surface 1a of the main body 1, and the surface of the third conductive part 23 is flush with the bottom surface 1b of the main body 1. For example, grooves can be provided on the top surface 1a and the bottom surface 1b of the main body 1, and the first conductive part 21 and the third conductive part 23 can be embedded in the grooves. On the one hand, this can better protect the first conductive layer 21 and the third conductive layer 23 and effectively prevent them from falling off. On the other hand, it can make the top surface 1a and the bottom surface 1b of the main body 1 flatter, which is more conducive to connecting other structures.

[0049] In some embodiments, such as Figure 11As shown, a protective layer 4 can also be affixed to the top surface of the main body 1, covering the first conductive part 21. The protective layer can be, for example, a glass layer, which not only improves the user's touch operation experience but also effectively protects the first conductive part 21 by covering it from prolonged contact with sweat from fingers, water molecules in the air, etc., preventing oxidation and affecting the transmission of electrical signals. In other embodiments, the protective layer 4 can also be a Mylar layer, which can be adhered to the top surface 1a of the main body 1 using adhesive. The protective layer 4 can also be an ink layer directly coated or printed on the top surface of the main body 1.

[0050] In some embodiments, such as Figure 19 As shown, the first conductive part 21 includes multiple parts. Along the length direction of the main body 1, the main body 1 is divided into multiple conductive regions in 10mm increments. The multiple first conductive parts 21 are spaced apart and insulated from each other along the length direction of the main body 1, and each conductive region has at least two first conductive parts 21. The width of a human finger is approximately 10-20mm. By dividing the main body 1 into multiple conductive regions, with each region having at least two first conductive parts 21, when a user performs a touch operation, regardless of whether the user touches the main body 1 with their finger perpendicular to its length direction, as... Figure 19 As shown on the left, the user touches the main body 1 with their finger in a manner consistent with the length direction of the main body 1, as follows: Figure 19 As shown in the touch mode on the right, no matter where the user's finger is placed on the main body 1, at least two first conductive parts 21 are in contact with the user's finger. At this time, even if one of the first conductive parts 21 fails and cannot transmit current, the other first conductive part 21 can still work normally and transmit current.

[0051] In some embodiments, see Figure 3 , Figure 6 and Figure 7 The bottom surface of the main body 1 is also recessed with a recess 14, which communicates with the through hole 11. The conductive member 2 also includes a fourth conductive part 24, which is located inside the recess 14. One end of the second conductive part 22 is connected to the first conductive part 21, and the other end is connected to the fourth conductive part 24. The end of the fourth conductive part 24 away from the second conductive part 22 is connected to the third conductive part 23. The fourth conductive part 24 can be filled inside the recess 14 or attached to the side wall of the recess 14.

[0052] In some embodiments, such as Figure 8As shown, the fourth conductive part 24 is attached to the side wall of the recessed part 14, and the fourth conductive part 24 includes a first sub-conductive part 24a and a second sub-conductive part 24b. The two ends of the first sub-conductive part 24a are connected to the second conductive part 22 and the third conductive part 23, respectively, and the two ends of the second sub-conductive part 24b are connected to the second conductive part 22 and the third conductive part 23, respectively. The first sub-conductive part 24a and the second sub-conductive part 24b are respectively attached to two opposite side walls of the recessed part 14. This arrangement can ensure the stability of signal transmission. For example, if the first sub-conductive part 24a fails, the second sub-conductive part 24b is unaffected and can continue to transmit signals. Furthermore, a groove can be provided in the side wall of the recessed part 14, and the fourth conductive part 24 is disposed in the groove so that the surface of the fourth conductive part 24 is flush with the surface of the side wall of the recessed part 14. Furthermore, in this embodiment, the third conductive part 23 is also configured as two parts, and the two third conductive parts 23 are respectively bent and connected to the first sub-conductive part 24a and the second sub-conductive part 24b, and attached to the bottom surface 1b of the main body 1.

[0053] In some embodiments, see Figure 7 Along the direction from the top surface 1a to the bottom surface 1b, the cross-sectional area of ​​the recess 14 gradually increases. Here, "cross-section" refers to the surface formed by cutting the main body 1 along a direction perpendicular to its thickness, i.e., from... Figure 7 As shown, the recessed part is roughly trapezoidal in shape, wider at the bottom and narrower at the top. This design is more conducive to laser engraving and can effectively improve production efficiency (for details, please refer to the description of laser engraving technology in the above embodiments, which will not be repeated here).

[0054] The above provides a detailed description of a button structure disclosed in the embodiments of this application. This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand a button structure and its core idea. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
