[0008] In one embodiment, the housing has a limiting portion protruding from the edge of the key through hole, and the limiting portion abuts against the outer periphery of the support section.

[0009] In one embodiment, the deformation cavity is located on the side of the support section away from the pressing section. The deformation cavity includes a first cavity segment and a second cavity segment. The second cavity segment is located on the side of the first cavity segment away from the pressing position. The cross-sectional area of ​​the first cavity segment gradually decreases in the direction from the support section to the pressing section.

[0010] In one embodiment, the voltage stabilizing structure is connected to the second cavity segment.

[0037] This application proposes a button.

[0038] Please see Figure 1 and Figure 5 In one embodiment of this application, the button 10 includes a pressing part 100 and a pressure stabilizing structure 170 disposed on the pressing part 100. The top of the pressing part 100 has a pressing position 140, and the bottom of the pressing part 100 is provided with a deformation cavity 130. The deformation cavity 130 is connected to the external space of the pressing part 100 through the pressure stabilizing structure 170.

[0039] Specifically, the pressing position 140 at the top of the pressing part 100 is the part that the user directly contacts and applies force to. The deformation cavity 130 is located at the bottom of the pressing part 100. By applying pressure to the pressing position 140, the deformation cavity 130 deforms, thereby realizing the pressing operation of the button 10.

[0040] The voltage stabilizing structure 170 connects the deformation cavity 130 to the external space of the pressing part 100. The voltage stabilizing structure 170 can be a perforated structure communicating with the deformation cavity 130. This perforated structure can be directly processed during the forming of the pressing part 100, thereby simplifying the processing flow and improving processing efficiency. Furthermore, by providing the voltage stabilizing structure 170 as a perforated structure in the pressing part 100, it avoids the need for opening holes in the circuit board 300, thereby increasing the density of electronic components and circuit distribution on the circuit board 300, making wiring on the circuit board 300 more convenient and the design simpler. The voltage stabilizing structure 170 can also be a pipe structure communicating with the deformation cavity 130, specifically a pipe inserted into the deformation cavity 130. The setting of the pressure stabilizing structure 170 helps to balance the air pressure inside and outside the deformation cavity 130, avoids the vacuum effect or air resistance caused by rapid pressing or releasing, effectively avoids the insufficient elasticity of the pressing part 100 after pressing down, thereby improving the rebound effect of the button 10 and ensuring the smooth operation of the button 10.

[0041] The technical solution of this application sets up a pressure stabilizing structure 170, which allows the deformation cavity 130 to communicate with the external space of the pressing part 100 through the pressure stabilizing structure 170. When the pressure applied to the pressing part 140 is removed, the air pressure in the deformation cavity 130 can be balanced with the external space of the pressing part 100, and the deformation cavity 130 can quickly recover its deformation. This prevents the pressing part 100 from failing to rebound properly due to the pressure in the deformation cavity 130 being lower than the external air pressure. This improves the rebound effect of the button 10.

[0042] In one implementation, please refer to Figure 1 and Figure 5 The voltage stabilizing structure 170 includes a first voltage stabilizing part and a second voltage stabilizing part that are connected to each other. The end of the first voltage stabilizing part away from the second voltage stabilizing part is connected to the deformation cavity, and the end of the second voltage stabilizing part away from the first voltage stabilizing part is connected to the external space of the pressing part.

[0043] The pressure stabilizing structure 170 can be a perforated structure formed by the pressing part 100, with the first pressure stabilizing part and the second pressure stabilizing part being two perforated sections respectively; the pressure stabilizing structure 170 can also be a tubular structure passing through the pressing part 100, with the first pressure stabilizing part and the second pressure stabilizing part being two tubular sections respectively; the pressure stabilizing structure 170 can also be a combination of a tubular structure and a perforated structure. Specifically, the perforated structure formed by the pressing part 100 has two openings, with at least one opening having a tubular structure. When only one opening has a tubular structure, the tubular structure can be located inside the deformation cavity 130 or in the external space of the pressing part 100. In this case, one of the first pressure stabilizing part and the second pressure stabilizing part is a perforated structure, and the other is a tubular structure. When both openings have tubular structures, one tubular structure is located inside the deformation cavity 130, and the other tubular structure is located in the external space of the pressing part 100. In this case, both the first pressure stabilizing part and the second pressure stabilizing part are tubular structures.

[0044] In one implementation, please refer to Figure 6 and Figure 7 The pressing part 100 has a mounting surface 160, which is located on the side opposite to the pressing position 140. The first pressure stabilizing part and the second pressure stabilizing part are both connected to the mounting surface 160.

[0045] The top of the pressing part 100 is the pressing position 140, and the opposite bottom is the mounting surface 160, used for connection or installation with other components (such as the circuit board 300 or other support structures). When the first and second pressure stabilizing parts are configured as perforated structures, the walls of the holes of the first and second pressure stabilizing parts are connected to the mounting surface 160. That is, the pressure stabilizing structure 170 is recessed from the mounting surface 160. Compared with the design that requires precise drilling through the entire pressing part 100, the recessed method from the mounting surface 160 is easier to manufacture and process, reduces the complexity of the production process, helps to reduce costs and improve production efficiency. At the same time, it also makes it easier to remove the pressing part 100 after it is formed in the mold during production, which is convenient for operation. When the first and second pressure stabilizing parts are configured as tubular structures, the walls of the first and second pressure stabilizing parts are connected to the mounting surface 160.

[0046] In other embodiments, the first voltage stabilizer and the second voltage stabilizer may be connected to the inner and outer peripheral walls of the deformation cavity 130, respectively, and have a gap between them and the mounting surface 160.

[0047] In one implementation, please refer to Figures 1 to 3The pressing part 100 includes a support section 120 and a pressing section 110 connected to each other. The pressing position 140 is located in the pressing section 110. The support section 120 is located on the side of the pressing section 110 away from the pressing position 140 and forms a stepped surface 150 with the pressing section 110. The button 10 also includes a housing 200. The housing 200 has a button through hole 210 corresponding to the pressing part 100. The stepped surface 150 abuts against the edge of the button through hole 210. A part of the pressing part 100 extends out of the button through hole 210.

[0048] The pressing part 100 includes a support section 120 and a pressing section 110. The outer peripheral surface of the support section 120 protrudes from the outer peripheral surface of the pressing section 110, so that the support section 120 has a stepped surface 150 on the side facing the pressing section 110. The housing 200 and the circuit board 300 enclose a mounting cavity, in which the pressing section 110 protrudes from the key through hole 210 for easy pressing operation; the support section 120 is installed in the mounting cavity, and the stepped surface 150 abuts against the edge of the key through hole 210. This not only provides positioning for the pressing part 100 during installation, but also reduces the possibility of the pressing part 100 loosening or shifting, making the button 10 more stable after installation and less prone to shaking, thus ensuring the overall structural stability of the button 10. The matching design of the stepped surface 150 and the edge of the key through hole 210 simplifies the installation process of the button 10, reduces assembly difficulty, and improves production efficiency. At the same time, it also prevents dust and other debris from entering the mounting cavity from around the key via 210 and affecting the performance of the circuit board 300.

[0049] In other embodiments, the pressing portion 100 may also have a uniform outer diameter in its extending direction, i.e., the cross-sectional areas of the support section 120 and the pressing section 110 in a plane perpendicular to their distribution direction are the same.

[0050] In one implementation, please refer to Figure 1 , Figure 3 and Figure 4 The outer casing 200 has a limiting part 220 protruding at the edge of the button through hole 210, and the limiting part 220 abuts against the outer periphery of the support section 120.

[0051] By abutting the limiting part 220 against the outer periphery of the support section 120, the non-axial movement of the pressing part 100 can be effectively restricted, greatly reducing the lateral displacement or tilting that may occur during operation, making the operation of the button 10 smoother and more reliable. The limiting part 220 effectively restricts the non-axial movement of the button 10, which helps to improve the accuracy of the button 10's trigger action, reduce the possibility of accidental touch, and ensure that each press accurately completes its intended function. The presence of the limiting part 220 can also play a certain guiding role, helping to quickly and accurately position the pressing part 100 during assembly, simplifying the installation process. The limiting part 220 can be annular, and depending on the shape of the outer periphery of the support section 120, it can be cylindrical or polygonal annular, with the limiting part 220 sleeved on the outer periphery of the support section 120; the limiting part 220 can also be L-shaped, limiting the support section 120 in at least two directions. In embodiments where multiple pressing parts 100 are provided, only one limiting part 220 may be provided, or each button through hole 210 may have a limiting part 220 corresponding to each support segment 120. Under the action of the limiting part 220, it is less likely for adjacent pressing parts 100 to experience linkage, thus reducing the probability of accidental triggering.

[0052] In one implementation, please refer to Figure 5 The deformation cavity 130 is located on the side of the support section 120 away from the pressing section 110. The deformation cavity 130 includes a first cavity section 131 and a second cavity section 132. The second cavity section 132 is located on the side of the first cavity section 131 away from the pressing position 140. The cross-sectional area of ​​the first cavity section 131 gradually decreases in the direction from the support section 120 to the pressing section 110.

[0053] The cross-sectional area of ​​the first cavity 131 gradually decreases from the support section 120 to the pressing section 110. When the user presses the pressing part 100, the first cavity 131 is more easily deformed, and the support section 120 and the pressing section 110 can be pressed down smoothly, allowing the pressing part 100 to be pressed smoothly and with less effort, thereby improving the convenience of pressing the button 10. The second cavity 132 is located on the side of the first cavity 131 away from the pressing position 140, and is used to guide and accommodate the conductive element 400, ensuring its correct movement during the operation of the button 10. Initially, the conductive element 400 can be completely located within the first cavity 131, or partially located within the first cavity 131 and partially located within the second cavity 132. The conductive element 400 has a certain distance from the contact point of the circuit board 300, which is provided by the second cavity 132. When the support section 120 and the pressing section 110 are pressed down, the first cavity section 131 deforms. Under the pressure of the support section 120 and the pressing section 110, the conductive element 400 also travels in the second cavity section 132 and abuts against the contact of the circuit board 300. After the force of the pressing position 140 disappears, the first cavity section 131 recovers its deformation, the support section 120 and the pressing section 110 rebound, the conductive element 400 returns to its initial position along the movement path, and the pressing part 100 returns to its initial state.

[0054] In other embodiments, the cross-sectional area of ​​the first cavity 131 is the same in the direction from the support section 120 to the pressing section 110.

[0055] In one implementation, please refer to Figure 5 The voltage stabilizing structure 170 is connected to the second cavity section 132.

[0056] When the pressing part 100 is deformed by force, the deformation of the second cavity 132 is small or almost non-existent, which can effectively reduce the risk of blockage of the pressure stabilizing structure 170 caused by the deformation of the pressing part 100. As a result, the air in the second cavity 132 can be smoothly discharged or drawn in through the pressure stabilizing structure 170 to balance the internal and external air pressure. The pressing part 100 can react more quickly after the user applies pressure and can also return to its original shape more quickly when the pressure is released, thereby improving the response speed and overall performance of the button 10.

[0057] In other embodiments, the voltage regulator 170 is connected to the first cavity 131; or the voltage regulator 170 is partially connected to the first cavity 131 and partially connected to the second cavity 132.

[0058] In one implementation, please refer to Figure 5 and Figure 8 The pressing section 110 has a uniform outer diameter in the direction from the support section 120 to the pressing section 110.

[0059] The pressing section 110 maintains a consistent outer diameter from its connection with the support section 120 to the top pressing position 140. This consistency ensures that the pressing section 110 has the same dimensions and structural strength throughout its entire length. The uniform outer diameter design is relatively simple, easy to process and produce, reducing manufacturing costs and improving production efficiency. Furthermore, the higher consistency of the pressing section 110 makes it easier to inspect and verify, thus facilitating quality control. In addition, the uniform outer diameter of the pressing section 110 means a more even material distribution, reducing the risk of stress concentration, especially in high-frequency use scenarios, and better resisting wear and deformation, thereby extending the service life of the button 10.

[0060] In another implementation, please refer to Figure 9 The pressing section 110 includes a contact section 111 and a transition section 112 connected to each other. The transition section 112 is located between the contact section 111 and the support section 120. The cross-sectional area of ​​the transition section 112 gradually decreases in the direction from the support section 120 to the pressing section 110.

[0061] The contact segment 111 is the part that the user directly interacts with, and the pressing position 140 is located on top of the contact segment 111. A transition segment 112 is located between the contact segment 111 and the support segment 120, with a gradually decreasing cross-sectional area, which helps to distribute the force applied to the contact segment 111 to the support segment 120 and the deformation cavity 130. The presence of the transition segment 112 enhances the reliability of the connection between the contact segment 111 and the support segment 120, reduces the risk of breakage between the pressing segment 110 and the support segment 120, thereby increasing the overall strength and stability of the button 10 structure. The length, shape, and number of transition segments 112 can be adjusted according to specific application requirements so that the button 10 can be adapted to various devices. Depending on different product requirements, the number of transition segments 112 can be one or more.

[0062] In one implementation, please refer to Figure 2 , Figure 8 and Figure 9 The shape of the pressing position 140 is circular, near-circular, polygonal, or near-polygonal.

[0063] The shape of the pressure point 140 can be circular or near-circular. A near-circular shape is a slightly modified circle, retaining rounded edges but deviating slightly from a perfect circular outline in some areas. Circular or near-circular shapes lack sharp corners, reducing the possibility of accidental presses and conforming more closely to the natural curves of the fingers, providing a more comfortable pressing experience. The shape of the pressure point 140 can also be polygonal, such as regular polygons like triangles, squares, and pentagons, or irregular or polygonal shapes. A near-polygonal shape is close to a polygon but with rounded corners or other subtle variations. Polygonal or near-polygonal shapes are visually more eye-catching, helping to distinguish different function keys, conveying more information through their geometric characteristics, and improving operational efficiency.

[0064] In one embodiment, the pressing part 100 is made of an elastic material.

[0065] The pressing part 100 is made of a material with high elasticity and resilience, such as silicone, rubber, or other synthetic elastomers. These elastic materials can deform under external force, and once the force is removed, they quickly return to their original shape, which is beneficial for the deformation and recovery of the deformation cavity 130. The elastic material provides good tactile feedback and reduces finger fatigue. The elastic material also has good wear resistance and anti-aging properties, helping to extend the lifespan of the button 10. Even after numerous pressing cycles, the elastic pressing part 100 is not prone to permanent deformation or damage.

[0066] In other embodiments, the pressing part 100 may also be made of materials such as metal or plastic.

[0067] In one implementation, please refer to Figure 5 The pressing part 100 is configured as an integral molding.

[0068] The one-piece molding eliminates potential weak points caused by the connection of multiple components (support section 120, pressing section 110, first cavity section 131, and second cavity section 132), improving the overall strength and stability of the pressing part 100 and making it more resistant to external impacts and wear from long-term use. The absence of seams or connection points also reduces the risk of material fatigue leading to cracks or fractures, thereby extending the service life of the pressing part 100. Furthermore, the one-piece molding of the pressing part 100 results in high reliability, requires no maintenance, and has low maintenance costs. In addition, the one-piece molding of the pressing part 100 greatly simplifies the production process, reduces assembly steps and time, thereby lowering production costs and improving production efficiency.

[0069] Furthermore, the multiple pressing parts 100 are integrally formed. The integrated design of the multiple pressing parts 100 makes the pressing parts 100 independent from the outer shell 200 and the circuit board 300, which can avoid the impact of vibration on the whole machine during transportation and reduce product maintenance costs.

[0070] In other embodiments, the pressing part 100 may also be provided separately.

[0071] In one implementation, please refer to Figure 5 The pressing part 100 is integrally molded from an elastic material, which not only simplifies the production process of the pressing part 100, but also improves the service life of the pressing part 100.

[0072] In one implementation, please refer to Figure 6 and Figure 7 The pressing part 100 also includes a conductive element 400, which is disposed in the deformation cavity 130.

[0073] The conductive element 400 is disposed within the deformation cavity 130 and is typically used to connect or disconnect circuits. When the pressing part 100 is subjected to force, causing the deformation cavity 130 to deform, it pushes the conductive element 400 inside to contact the contacts on the circuit board 300. When the force on the pressing part 100 is removed and the deformation cavity 130 returns to its original deformation, the conductive element 400 inside separates from the contacts on the circuit board 300, thereby realizing the switching function triggered by the button 10. The conductive element 400 is located within the deformation cavity 130, which protects the conductive element 400 from external environmental influences while ensuring the accuracy and stability of the button 10's operation.

[0074] In one implementation, please refer to Figure 6 and Figure 7 The deformation cavity 130 contains at least two conductive elements 400.

[0075] At least two conductive elements 400 are housed within a deformation cavity 130. These conductive elements 400 can operate independently or collaboratively. The presence of multiple conductive elements 400 increases the probability of the pressing part 100 triggering the circuit board 300 to conduct. Even if one conductive element 400 malfunctions (such as surface oxidation or contamination), the other conductive elements 400 can still ensure normal circuit operation, improving overall contact reliability and stability. Furthermore, the load on the pressing part 140 is distributed across multiple conductive elements 400, reducing the pressure and wear on each individual conductive element 400, thereby extending the lifespan of the entire button 10. In addition, the design of at least two conductive elements 400 allows the spacing of the conductive elements 400 to be adjusted according to the circuit layout of the circuit board 300, adapting to various circuit shapes of the circuit board 300 and offering strong practicality.

[0076] In other embodiments, only one conductive element 400 may be provided inside the deformation cavity 130. The side of the single conductive element 400 that contacts the contact point of the circuit board 300 has a large area in order to improve the triggering efficiency.

[0077] In one implementation, please refer to Figure 6 The conductive component 400 is configured as carbon black particles, and the outer surface of the carbon black particles is provided with a conductive layer.

[0078] Carbon black is a powdery substance composed of carbon elements, possessing high electrical conductivity and good chemical stability. Using carbon black granules as the base material for the conductive component 400 in button 10 allows for the connection or disconnection of circuits using its conductivity. A conductive layer is applied to the outer surface of the carbon black granules, further enhancing their conductivity. This conductive layer can be made of metal (such as silver, copper, etc.) or other conductive materials, or it can be a conductive adhesive coated on the outer surface of the carbon black granules to ensure conductivity efficiency. The combination of carbon black granules and a conductive layer not only enhances conductivity but also improves the overall chemical stability and wear resistance of the material. The material and thickness of the conductive layer can be adjusted according to specific needs to adapt to different electrical requirements. As a relatively economical raw material, carbon black, combined with its high efficiency, allows the conductive component 400 to achieve high performance while controlling manufacturing costs. Furthermore, using granular carbon black granules instead of a solid material also helps save resources.

[0079] In other embodiments, the conductive element 400 may also be made directly from a conductive material (such as silver, copper, etc.).

[0080] In one implementation, please refer to Figure 6 and Figure 7 The deformation cavity 130 contains at least two carbon black particles, and the outer surface of the carbon black particles is provided with a conductive layer. This reduces the manufacturing cost of the pressing part 100 and improves the reliability of the contact between the pressing part 100 and the circuit board 300.

[0081] In one implementation, please refer to Figure 6 and Figure 7 The pressing part 100 is provided with multiple parts, and the deformation cavities 130 of two adjacent pressing parts 100 are connected by a pressure stabilizing structure 170.

[0082] The button 10 includes multiple pressing portions 100, each with its own deformation cavity 130. At least one deformation cavity 130 of a pressing portion 100 is directly connected to the outside via a pressure stabilizing structure 170, and the deformation cavities 130 of adjacent pressing portions 100 are also interconnected via the pressure stabilizing structure 170. This allows air to flow freely between the deformation cavities 130 of each pressing portion 100, helping to balance the air pressure changes within the entire button 10 structure. The interconnected design of the pressure stabilizing structures 170 accelerates the speed of air inflow and outflow, and the pressure changes within the deformation cavities 130 of each pressing portion 100 can be distributed and processed through multiple paths, thereby accelerating the pressing and rebound speed of the button 10 and improving the overall response speed.

[0083] In one implementation, please refer to Figure 6 and Figure 7 The voltage stabilizing structure 170 includes a first voltage stabilizing structure 171 and a second voltage stabilizing structure 172. Each pair of adjacent pressing parts 100 are connected through the first voltage stabilizing structure 171. Among the multiple pressing parts 100, the pressing parts 100 located on the side are connected to the external space of the button 10 through the second voltage stabilizing structure 172. The cross-sectional area of ​​the second voltage stabilizing structure 172 is less than or equal to the cross-sectional area of ​​the first voltage stabilizing structure 171.

[0084] The multiple pressing parts 100 in the button 10 are arranged neatly in a certain row and column order, which helps with a compact design and facilitates user identification and operation. The smaller cross-sectional area of ​​the second voltage stabilizing structure 172 reduces the entry of dust and foreign objects into the deformation cavity 130, thus contaminating the conductive component 400 and ensuring the conductivity of the conductive component 400. This also reduces the probability of accidental touches (where a press operation is performed but there is no response) of the conductive component 400. The larger design of the first voltage stabilizing structure 171 helps control the airflow, allowing more air to enter and exit through the first voltage stabilizing structure 171. This allows for a faster and more effective balance of air pressure changes within the entire button 10 structure, reducing operating resistance and ensuring smoother operation of the button 10.

[0085] In other embodiments, the cross-sectional area of ​​the second voltage regulator 172 may also be larger than the cross-sectional area of ​​the first voltage regulator 171.

[0086] This application also proposes an electronic device, which includes a button 10. The specific structure of the button 10 is as described in the above embodiments. Since this electronic device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
