Description

Technical Field

[0001] This application relates to the field of control electrical components technology, specifically to a button structure. Background Technology

[0002] Currently, many products and devices, such as mobile phones, laptops, cars, and digital display instruments, inevitably need to be equipped with buttons for various operations, and these buttons are often used in conjunction with panels and transparent sheets.

[0003] In existing technologies, buttons are typically fixed using a panel and a transparent sheet. The panel has a through hole to expose the active end of the button, making it easy for the operator to press the button and thus touch the circuit board located below the transparent sheet.

[0004] However, the stability of button placement on the panel and transparent sheet in the existing technology is poor, and the buttons are easy to remove from the panel. Utility Model Content

[0005] This application provides a button structure to improve the stability of the button setting on the panel and transparent sheet, and reduce the possibility of the button being removed from the panel.

[0006] To achieve the above objectives, this application provides a button structure, including a panel, a button, and a transparent sheet. The panel has a through hole. The button includes a connecting portion and a pressing portion, the pressing portion having an actuating end and a contact end disposed opposite to each other. The connecting portion is located on one side of the panel, and the actuating end passes through the through hole to the other side of the panel. The transparent sheet is disposed on the panel, and the connecting portion is clamped between the transparent sheet and the panel. A limiting post is provided on the side of the transparent sheet near the panel, and a limiting hole cooperating with the limiting post is provided on the connecting portion. The transparent sheet also has a clearance hole corresponding to the pressing portion, so that when the actuating end is pressed, the contact end passes through the clearance hole to make contact with the circuit board.

[0007] When using the above technical solution, the connecting part is located between the transparent sheet and the panel when connecting the transparent sheet and the panel, and the connecting part is clamped between the transparent sheet and the panel. This allows for the precise positioning and installation of the buttons, preventing them from becoming loose or misaligned during use. Furthermore, the buttons can be installed between the transparent sheet and the panel directly when connecting them, eliminating the need for additional connecting structures. This simplifies the button installation process and makes operation more convenient.

[0008] Furthermore, a limiting post is provided on the side of the transparent sheet near the panel, and a limiting hole is provided on the connecting part to cooperate with the limiting post.

[0009] During installation, aligning the limiting post with the limiting hole facilitates the positioning and installation of the transparent panel and buttons, simplifying the assembly process and improving efficiency. Furthermore, it enhances the positional accuracy between the buttons and the transparent panel, ensuring precise positioning of the transparent panel, buttons, and panel during connection, thereby improving overall assembly quality.

[0010] After the transparent sheet is connected to the panel, the limiting post and the limiting hole cooperate, and the limiting post is inserted into the limiting hole to form a stable mechanical connection. This improves the stability of the button placement between the panel and the transparent sheet, and reduces the possibility of the button being removed from the panel. It also prevents relative movement between the button and the transparent sheet during use, reduces the impact of external impacts and vibrations on the button structure, and thus improves the overall durability of the button structure.

[0011] In one possible implementation, there are multiple pressing parts, and the multiple pressing parts and connecting parts are integrally formed.

[0012] When the above technical solution is adopted, there are multiple pressing parts. By integrating multiple pressing parts into a connecting part, the number of independent parts is reduced, the spatial layout is optimized, and the spatial efficiency, functional density and operational reliability of the buttons are improved.

[0013] The pressing part and the connecting part are integrally formed, meaning that the button is formed in one process during the manufacturing process.

[0014] This reduces stress concentration issues associated with bolted or welded connections, ensuring higher dimensional accuracy and consistency, and enhancing the structural strength of the buttons. Furthermore, the elimination of machining requirements during button fabrication reduces material usage and waste. Additionally, the integrated structure minimizes connection points, lowering the risk of failures due to loose connections, corrosion, or fatigue, and improving fatigue resistance. Moreover, it reduces the number of parts and assembly steps, simplifying the operational process.

[0015] Furthermore, the pressing part and the connecting part are integrally molded, and there will be no gap between the pressing part and the connecting part, which can reduce the possibility of liquids, dust and other substances entering the inside of the button.

[0016] In one possible implementation, a support portion is provided on the side of the transparent sheet near the panel, which is used to support the connection position of two adjacent pressing portions.

[0017] When the above technical solution is adopted, when the operator presses one of the pressing parts, causing the pressing part to deform and move towards the transparent sheet, the support column can be supported at the connection position of two adjacent pressing parts to prevent the other pressing parts from moving towards the transparent sheet synchronously with the pressed pressing part, thus avoiding deformation of other pressing parts and preventing accidental contact with other contacts on the circuit board.

[0018] In one possible implementation, a first recess is provided on the connecting part on the side of the button away from the transparent sheet, and the first recess is arranged circumferentially along the pressing part.

[0019] When the above technical solution is adopted, the setting of the first recessed part makes the pressing part and the connecting part have a deformation area, which makes it easy for the pressing part to move relative to the connecting part, making the button easier to press and improving the feel.

[0020] Meanwhile, the first recess can be understood as a chamfer set at the connection position of the pressing part and the connecting part. When external force is applied to the pressing part, it can disperse the stress between the pressing part and the connecting part, which can improve the service life of the button.

[0021] In one possible implementation, the panel is provided with a first protrusion that mates with the first recess.

[0022] When the above technical solution is adopted, when the connecting part is clamped between the transparent sheet and the panel, the first recessed part and the first protruding part cooperate to make the button and the panel fit tightly together, thereby improving the stability of the button setting between the transparent sheet and the panel.

[0023] At the same time, the first recessed part and the first protruding part cooperate to improve the sealing between the panel and the connecting part, effectively preventing water, dust and other substances from entering the product containing the button structure through the connection between the button and the panel.

[0024] In one possible implementation, the button structure further includes a sealing ring that mates with the first recess and is located between the panel and the pressing part.

[0025] When the above technical solution is adopted, when the connecting part is clamped between the transparent sheet and the panel, the sealing ring is located between the panel and the pressing part, and the sealing ring cooperates with the first recessed part, which can improve the sealing between the panel and the connecting part and effectively prevent water, dust and other substances from entering the product containing the button structure provided in the embodiments of this application through the connection between the button and the panel.

[0026] In addition, in specific implementation, the first protrusion or sealing ring can be used in conjunction with the first recess, which is convenient to select according to the actual situation.

[0027] In one possible implementation, on the side of the button near the transparent sheet, along the circumference of the pressing part, there is one of a second recess and a second protrusion that cooperate with each other, and the transparent sheet is provided with the other of the second recess and the second protrusion.

[0028] When the above technical solution is adopted, when the connecting part is clamped between the transparent sheet and the panel, the second recess and the second protrusion cooperate to further make the button and the panel fit tightly together, thereby improving the stability of the button setting between the transparent sheet and the panel.

[0029] At the same time, the second recess and the second protrusion work together to improve the sealing between the panel and the connecting part, effectively preventing water, dust and other substances from entering the product containing the button structure through the connection between the button and the panel.

[0030] In one possible implementation, a third protrusion is provided on the side of the transparent sheet near the panel, the third protrusion surrounds the connecting part, and the third protrusion abuts against the panel.

[0031] When the above technical solution is adopted, the third protrusion can effectively prevent water, dust, etc. from entering the product containing the button structure provided in the embodiments of this application through the buttons. At the same time, it can also prevent water, dust, and other foreign objects from entering the buttons through the display port and causing contamination or even damage to the circuit board.

[0032] In one possible implementation, one end of the limiting post passes through the limiting hole and presses against the panel.

[0033] When the above technical solution is adopted, the limiting post provides additional physical support for the transparent sheet and the button, which can improve the stability of the button between the transparent sheet and the panel, so as to ensure the normal operation of the button.

[0034] In one possible implementation, a distinguishing mark is provided between two adjacent pressing parts.

[0035] When using the above technical solution, the setting of distinguishing marks can not only improve the accuracy of user operation, but also enhance the aesthetics of the buttons and the user experience. Attached Figure Description

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0051] The directional terms appearing in the following description refer to the directions shown in the figures and are not intended to limit the specific structure of this application.

Therefore, they should not be construed as limitations on this application.

[0052] Furthermore, the terms "first," "second," etc., in the specification and claims of this application or in the aforementioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0053] In the description of this application, unless otherwise stated, "multiple" means two or more (including two), and similarly, "multiple groups" means two or more (including two groups).

[0054] Please refer to Figures 1 to 3 As shown, this application embodiment provides a button structure, which includes a panel 1, a button 2 and a transparent sheet 3, with a through hole 11 on the panel 1.

[0055] In practice, button 2 can be made of silicone, which allows it to deform to a certain extent under external force. When the external force disappears, button 2 can return to its original shape.

[0056] The transparent sheet 3 is made of a transparent material. For example, the material of the transparent sheet 3 can be plastic. Of course, the materials of the button 2 and the transparent sheet 3 are only illustrative examples and are not intended to be specific limitations. The material of the panel 1 is also not specifically limited here.

[0057] In practice, a circuit board is provided on the side of the transparent sheet 3 away from the panel 1, and the contacts on the circuit board correspond to the buttons 2. When button 2 is pressed, the contacts on the circuit board are touched, thereby realizing the corresponding function.

[0058] In addition, a display screen is provided on the side of the transparent sheet 3 that is away from the panel 1.

[0059] like Figure 1 and Figure 4 As shown, a display port 12 is also provided on the panel 1. The display port 12 corresponds to the display screen so that the operator can observe the content displayed on the display screen through the display port 12 and the position of the transparent sheet 3 corresponding to the display port 12.

[0060] The shape of the display port 12 matches the shape of the display screen, and is not specifically limited here. For example, the shape of the display port 12 can be circular, polygonal, or other shapes. In the embodiments provided in this application, such as... Figure 1 and Figure 4 As shown, the shape of the display port 12 is rectangular.

[0061] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The button 2 includes a connecting part 21 and a pressing part 22. The four peripheral edges of the pressing part 22 are connected to the connecting part 21. The pressing part 22 has an action end and a contact end that are arranged opposite to each other.

[0062] In practice, the operator can press the action end, which will cause the button 2 to deform to a certain extent, causing the contact end to move closer to the circuit board and make contact with the corresponding contact point on the circuit board, thereby realizing the corresponding function.

[0063] When the external force disappears, the contact end moves away from the circuit board, allowing button 2 to return to its original state.

[0064] Combination Figure 2 , Figure 5 and Figure 6 As shown, the pressing part 22 includes an action part 222 and a contact part 223, with the contact part 223 disposed on the action part 222. The four periphery of the action part 222 is connected to the connecting part 21. The side of the action part 222 away from the transparent sheet 3 protrudes from the surface of the connecting part 21, and this side is the action end. The side of the contact part 223 away from the action part 222 is the contact end. Furthermore, a groove is provided on the side of the action part 222 near the transparent sheet 3, creating an action space between the action part 222 and the transparent sheet 3. This allows the action part 222 to move the contact part 223 closer to the transparent sheet 3 when an external force is applied to it, thereby bringing the contact part 223 into contact with the circuit board.

[0065] One end of the contact portion 223 is disposed on the groove wall of the groove. The connection method between the contact portion 223 and the function portion 222 is not specifically limited here. For example, the contact portion 223 can be fixedly disposed on the function portion 222 by means of welding, bonding or other methods.

[0066] The structure of the contact portion 223 can be a cylindrical structure, a block structure, etc., but it is not limited to these in practice.

[0067] The through hole 11 on panel 1 can correspond to the functional portion 222, and the shape of the through hole 11 matches the shape of the functional portion 222. For example, when the functional portion 222 is circular, the through hole 11 can also be circular. In the embodiment provided in this application, the functional portion 222 is a rectangular structure, and the shape of the through hole 11 is also rectangular.

[0068] Combination Figures 1 to 3 As shown, the connecting part 21 is located on one side of the panel 1, and the working end passes through the through hole 11 to the other side of the panel 1. The transparent sheet 3 is disposed on the panel 1, and the connecting part 21 is clamped between the transparent sheet 3 and the panel 1.

[0069] It should be noted that the size of the through hole 11 is smaller than the size of the connecting part 21, so as to ensure that the functional end can pass through the through hole 11 and prevent the connecting part 21 from passing through the through hole 11, thereby realizing that the connecting part 21 is located on one side of the panel 1 and the functional end is located on the other side of the panel 1. Furthermore, the connecting part 21 is positioned between the transparent sheet 3 and the panel 1.

[0070] The connection method between the transparent sheet 3 and the panel 1 is not specifically limited here, but shall be subject to the actual situation. For example, the transparent sheet 3 and the panel 1 can be connected together by means of screws, rivets, snap-fits, etc.

[0071] In the embodiments provided in this application, the transparent sheet 3 and the panel 1 are connected together by welding. Thus, the weld seam serves as a seal, reducing the possibility of foreign objects entering the product containing the button structure through the button structure in harsh environments such as rain spills, splashes, and high dust levels.

[0072] When connecting the transparent sheet 3 and the panel 1, the connecting part 21 is located between the transparent sheet 3 and the panel 1, and the connecting part 21 is clamped between the transparent sheet 3 and the panel 1. This allows for the positioning and installation of the button 2, preventing it from becoming loose or misaligned during use. Furthermore, when connecting the transparent sheet 3 and the panel 1, the button 2 can be installed between them without the need for an additional connecting structure, simplifying the button installation process and making it more convenient.

[0073] Moreover, combined Figure 1 and Figure 7 As shown, a limiting post 31 is provided on the side of the transparent sheet 3 near the panel 1, and a limiting hole 211 that cooperates with the limiting post 31 is provided on the connecting part 21.

[0074] During installation, aligning the limiting post 31 with the limiting hole 211 facilitates the positioning and installation of the transparent sheet 3 and the button 2, simplifying the assembly process and improving assembly efficiency. Furthermore, it enhances the positional accuracy between the button 2 and the transparent sheet 3, ensuring precise positioning of the transparent sheet 3, button 2, and panel 1 during connection, thereby improving the overall assembly quality.

[0075] After the transparent sheet 3 is connected to the panel 1, the limiting post 31 cooperates with the limiting hole 211, and the limiting post 31 is inserted into the limiting hole 211, which can form a stable mechanical connection, improve the stability of the button 2 between the panel 1 and the transparent sheet 3, and reduce the possibility of the button 2 being removed from the panel 1. It can also prevent the button 2 and the transparent sheet 3 from moving relative to each other during use, reduce the impact of external impacts and vibrations on the button structure, and thus improve the overall durability of the button structure.

[0076] In practice, the number of limit posts 31 is not specifically limited here. For example, the number of limit posts 31 can be one, two, three, four or more.

[0077] In practice, the number of limiting posts 31 is required to be multiple. When the number of limiting posts 31 is multiple, the multiple limiting posts 31 are distributed or symmetrically arranged to facilitate the positioning of the button 2 and the transparent sheet 3, and to improve the stability of the button 2 between the transparent sheet 3 and the panel 1.

[0078] The limiting post 31 can be set on the transparent sheet 3 by welding, bonding, threaded connection, etc., but it is not limited to these methods in practice.

[0079] In addition, combined Figure 1 , Figure 2 and Figure 7 As shown, the transparent sheet 3 also has a clearance hole 32 corresponding to the pressing part 22, so that when the pressing end is applied, the contact end passes through the clearance hole 32 to press and contact the circuit board.

[0080] The active end is located on the side of panel 1 away from the transparent sheet 3, and the contact end is positioned opposite the active end. When the operator presses the active end, the button 2 deforms, and the contact end moves towards the circuit board, allowing it to pass through the clearance hole 32 and contact the circuit board.

[0081] In one possible implementation, refer to Figure 2 and Figure 5 There are multiple pressing parts 22, and the multiple pressing parts 22 and the connecting parts 21 are integrally formed.

[0082] Thus, there are multiple pressing parts 22. By integrating multiple pressing parts 22 onto a single connecting part 21, the number of independent components is reduced, the spatial layout is optimized, and the space efficiency, functional density, and operational reliability of the button 2 are improved.

[0083] Multiple pressing parts 22 and connecting parts 21 are integrally formed, that is, the button 2 is formed in one process during the manufacturing process.

[0084] This reduces stress concentration issues associated with bolted or welded connections, ensuring higher dimensional accuracy and consistency, and enhancing the structural strength of button 2. Furthermore, the elimination of machining requirements for button 2 reduces material usage and waste. The integrated structure also minimizes connection points, lowering the risk of failures due to loose connections, corrosion, or fatigue, and improving fatigue resistance. Additionally, it reduces the number of parts and assembly steps for button 2, simplifying the operation process.

[0085] Furthermore, the pressing part 22 and the connecting part 21 are integrally formed, and there is no gap between the pressing part 22 and the connecting part 21, which can reduce the possibility of liquids, dust and other substances entering the inside of the button 2.

[0086] In practice, the number of pressing parts 22 can be two, three, four, or more, and there is no specific limitation here. The arrangement of multiple pressing parts 22 is also not specific.

[0087] In the embodiments provided in this application, such as Figure 2 , Figure 5 as well as Figure 6 As shown, there are four pressing parts 22, and each of the four pressing parts 22 corresponds to one connecting part 21. The four pressing parts 22 are arranged sequentially in one direction.

[0088] When there are multiple pressing parts 22, each pressing part 22 corresponds to one through hole 11, such as... Figure 1 As shown. The shape of the through hole 11 matches the plurality of pressing parts 22.

[0089] It should also be noted that when there are multiple pressing parts 22, there can be multiple clearance holes 32, and each clearance hole 32 can correspond one-to-one with a pressing part 22. Of course, in practice, one clearance hole 32 can also correspond to multiple pressing parts 22; no specific limitation is made here, and the actual situation shall prevail.

[0090] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 7 A support portion 33 is provided on the side of the transparent sheet 3 near the panel 1. The support portion 33 is used to support the connection position of two adjacent pressing portions 22.

[0091] Thus, when an operator presses one of the pressing parts 22, causing the pressing part 22 to deform and move towards the transparent sheet 3, the support column can support the connection position of two adjacent pressing parts 22 to prevent the other pressing parts 22 from moving towards the transparent sheet 3 in sync with the pressed pressing part 22, thereby preventing other pressing parts 22 from deforming and thus avoiding accidental contact with other contacts on the circuit board.

[0092] In specific implementation, a support part 33 is provided between each pair of adjacent pressing parts 22. Figure 5 and Figure 7 As shown, when there are four pressing parts 22, and the four pressing parts 22 are arranged sequentially in one direction, and the four pressing parts 22 correspond to four clearance holes 32 respectively, there are three support parts 33. The arrangement direction of the three support parts 33 is the same as the arrangement direction of the pressing parts 22, and a support part 33 is provided between each pair of adjacent clearance holes 32.

[0093] The method by which the support portion 33 is disposed on the transparent sheet 3 is not specifically limited here. For example, the support portion 33 can be disposed on the transparent sheet 3 by means of bonding, welding, etc. Of course, it is not limited to this in practice.

[0094] As one possible implementation, refer to Figure 2 , Figure 3 and Figure 5 As shown, on the side of button 2 away from transparent sheet 3, a first recess 212 is provided on the connecting part 21, and the first recess 212 is arranged circumferentially along the pressing part 22.

[0095] Thus, the first recessed portion 212 creates a deformation area between the pressing portion 22 and the connecting portion 21, making it easier for the pressing portion 22 to move relative to the connecting portion 21, thereby making the button 2 easier to press and improving the feel.

[0096] Meanwhile, the first recess 212 can be understood as a chamfer provided at the connection position between the pressing part 22 and the connecting part 21. When an external force is applied to the pressing part 22, it can disperse the stress between the pressing part 22 and the connecting part 21, thereby improving the service life of the button 2.

[0097] In practice, the first recessed portion 212 can be formed when the pressing portion 22 and the connecting portion 21 are integrally formed.

[0098] It should be noted that when a connecting part 21 is provided with multiple pressing parts 22, it is assumed that the multiple pressing parts 22 form a pressing part 22 group, and the first recessed part 212 corresponds to the outer periphery of the pressing part 22 group.

[0099] like Figure 5As shown, in the embodiments provided in this application, one connecting part 21 corresponds to four pressing parts 22, and when the four pressing parts 22 are arranged sequentially in one direction, the first recessed part 212 is disposed on the outer periphery of the four pressing parts 22.

[0100] As an example, combined Figure 3 and Figure 4 As shown, panel 1 is provided with a first protrusion 13 that cooperates with the first recess 212.

[0101] In this case, when the connecting part 21 is clamped between the transparent sheet 3 and the panel 1, the first recessed part 212 cooperates with the first protruding part 13, which can make the button 2 fit tightly with the panel 1, and improve the stability of the button 2 between the transparent sheet 3 and the panel 1.

[0102] Meanwhile, the first recessed portion 212 cooperates with the first protruding portion 13 to improve the sealing between the panel 1 and the connecting portion 21, effectively preventing water, dust and other substances from entering the product containing the button structure provided in this application embodiment through the connection between the button 2 and the panel 1.

[0103] In practice, the first protrusion 13 can be fixedly mounted on the panel 1 by welding, snap-fitting, or other methods. Of course, in actual operation, the panel 1 can also be integrally formed, and the first protrusion 13 can be formed together with the panel 1.

[0104] As another example, the button structure provided in this application embodiment also includes a sealing ring, which cooperates with the first recess 212 and is located between the panel 1 and the pressing part 22.

[0105] In this case, when the connecting part 21 is clamped between the transparent sheet 3 and the panel 1, the sealing ring is located between the panel 1 and the pressing part 22, and the sealing ring cooperates with the first recessed part 212, which can improve the sealing between the panel 1 and the connecting part 21, and effectively prevent water, dust and other substances from entering the product containing the button structure provided in the embodiment of this application through the connection between the button 2 and the panel 1.

[0106] In addition, in specific implementation, the first protrusion 13 or the sealing ring can be used in conjunction with the first recess 212, which is convenient to select according to the actual situation.

[0107] In practice, the structure of the sealing ring matches the structure of the first recess 212. The sealing ring can be welded or bonded to the panel 1.

[0108] As one possible implementation method, combined with Figure 1 , Figure 6 and Figure 7As shown, on the side of button 2 near transparent sheet 3, along the circumference of pressing part 22, one of a second recess 221 and a second protrusion 34 is provided, which cooperate with each other, and the other of the second recess 221 and the second protrusion 34 is provided on transparent sheet 3.

[0109] Thus, when the connecting part 21 is clamped between the transparent sheet 3 and the panel 1, the second recess 221 and the second protrusion 34 cooperate to further ensure that the button 2 and the panel 1 fit tightly together, thereby improving the stability of the button 2 between the transparent sheet 3 and the panel 1.

[0110] At the same time, the second recess 221 and the second protrusion 34 cooperate to improve the sealing between the panel 1 and the connecting part 21, effectively preventing water, dust and other substances from entering the product containing the button structure through the connection between the button 2 and the panel 1.

[0111] At this time, when the connecting part 21 is clamped between the transparent sheet 3 and the panel 1, the first protrusion 13 and the first recess 212 cooperate, and the second recess 221 and the second protrusion 34 cooperate to form two lines of defense, which enhances the stability of the button 2 between the transparent sheet 3 and the panel 1, and improves the sealing between the panel 1 and the connecting part 21.

[0112] In a specific implementation, a second recessed portion 221 can be provided circumferentially on the pressing portion 22, and correspondingly, a second protruding portion 34 can be provided on the transparent sheet 3. Alternatively, a second protruding portion 34 can be provided circumferentially on the pressing portion 22, and correspondingly, a second recessed portion 221 can be provided on the transparent sheet 3. No specific limitation is made here; the actual situation shall prevail.

[0113] In the embodiments provided in this application, such as Figure 6 As shown, a second recess 221 is provided circumferentially in the pressing part 22. For example... Figure 1 , Figure 3 and Figure 7 As shown, a second protrusion 34 is provided on the transparent sheet 3.

[0114] In actual processing, both button 2 and transparent sheet 3 can be integrally formed. When integrally forming button 2, a second recessed portion 221 can be formed, and when integrally forming transparent sheet 3, a second protruding portion 34 can be formed.

[0115] In some embodiments, such as Figure 7 As shown, a third protrusion 35 is provided on the side of the transparent sheet 3 near the panel 1. The third protrusion 35 surrounds the connecting part 21 and abuts against the panel 1.

[0116] At this time, the third protrusion 35 effectively prevents water, dust, and other contaminants from entering the product containing the button structure provided in this embodiment through the button 2. Simultaneously, it also prevents water, dust, and other foreign objects from entering the button 2 through the display port 12, thus preventing contamination or even damage to the circuit board.

[0117] In practice, when welding panel 1 and transparent sheet 3, the weld can extend along the length of the third protrusion 35 to facilitate operation.

[0118] As an alternative, one end of the limiting post 31 passes through the limiting hole 211 and is pressed against the panel 1.

[0119] Thus, the limiting post 31 provides additional physical support for the transparent sheet 3 and the button 2, which can improve the stability of the button 2 between the transparent sheet 3 and the panel 1, so as to ensure the normal operation of the button 2.

[0120] like Figure 5 As shown, a distinguishing mark 23 is provided between two adjacent pressing parts 22.

[0121] The setting of the distinguishing mark 23 not only improves the accuracy of user operation, but also enhances the aesthetics and user experience of button 2.

[0122] In practice, the distinguishing mark 23 can be an icon, symbol, or text label, or it can be a groove, etc. The specific form of the distinguishing mark 23 is not specifically limited here, and shall be subject to the actual situation.

[0123] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, "connection" or "joining" in mechanical structures can refer to a physical connection, such as a fixed connection, for example, a connection fixed by a partition, such as a connection fixed by screws, bolts, or other partitions; a physical connection can also be a detachable connection, such as a snap-fit ​​or interlocking connection; a physical connection can also be an integral connection, such as a connection formed by welding, bonding, or integral molding. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
