Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a piano-style control button. Background Technology

[0002] Existing buttons generally lack refined design for tactile feedback, resulting in a lack of responsiveness when pressed and failing to provide a pleasant user experience. Furthermore, their arrangement is often either disordered or a single, uniform layout, making efficient functional integration difficult within limited installation space. They also lack intuitive visual differentiation, increasing the risk of accidental presses during rapid operation. Utility Model Content

[0003] Therefore, it is necessary to provide a piano-style control button to address the problem of the lack of tactile feedback in the control buttons.

[0004] A piano-style control key includes: a housing assembly; multiple first keys arranged adjacent to each other on the housing assembly, with portions of adjacent first keys forming mounting spaces; multiple second keys spaced at intervals on the housing assembly, each second key corresponding to one of the mounting spaces; a circuit board assembly disposed on the housing assembly; and multiple spring-loaded components, portions of which are clamped between the multiple first keys and the circuit board assembly, and other portions of which are clamped between the multiple second keys and the circuit board assembly, and the spring-loaded components are electrically connected to the circuit board assembly.

[0005] The aforementioned design discloses a piano-style control button, employing a combination of multiple first and second buttons. This design not only replicates the classic black and white key layout of a piano but also achieves a compact arrangement through corresponding installation space. It efficiently integrates multiple control buttons within the limited space of the housing components, meeting the multi-level operation needs of appliances or screens. A spring-loaded mechanism forms a stable elastic support between the first and second buttons and the circuit board assembly. Pressing the button allows for a rapid rebound, ensuring quick operation response and simulating the tactile feel of piano keys. Combined with the piano-like sound emitted when the buttons are triggered, this transforms the mundane process of appliance control into a fun and interactive experience, particularly suitable for enhancing user enjoyment in home settings. The corresponding trigger structure between the circuit board assembly and the buttons ensures stable signal transmission with each press, enabling precise control of appliance switching, mode adjustment, or screen interaction. This innovative design, combining musical instrument aesthetics with practical control functions, breaks through the monotonous experience of traditional buttons while also considering the durability and functionality of industrial products.

[0006] In one embodiment, the first button includes a first button body and a first locking block. One end of the first button body contacts the spring-loaded component. The first button body is disposed opposite to the circuit board assembly. There are two first locking blocks, each disposed on the first button body and located away from the end of the first button body that contacts the spring-loaded component. The two first locking blocks are engaged with the housing assembly. Two adjacent first button bodies cooperate to form an installation space. By contacting the spring-loaded component with one end of the first button body and displacing it opposite to the circuit board assembly, when the first button body is pressed, it directly acts on the spring-loaded component, causing it to deform. Simultaneously, it transmits a trigger signal to the circuit board assembly, ensuring that the pressing operation is quickly converted into an electrical signal output, providing a reliable command source for electrical appliance or screen control. The elastic restoring force of the spring-loaded component can also efficiently push the button back to its original position through contact with the first button body, ensuring the continuity of operation. The two first locking blocks, disposed at the end of the first button body away from the spring-loaded component and engaged with the housing assembly, form a stable installation and positioning structure. This locking method not only firmly fixes the first button to the housing assembly, preventing it from shifting or wobbling during pressing or rebounding, but also restricts the button's movement trajectory, ensuring that each press follows a preset direction, thus improving operational accuracy and structural durability. Furthermore, the two adjacent first button bodies work together to form an installation space, demonstrating structural synergy. The installation space corresponds one-to-one with the second button, fully utilizing the gaps between adjacent first buttons to achieve a compact and streamlined button layout. The orderly arrangement of the first and second buttons further replicates the classic black and white key distribution of a piano, laying the foundation for the overall aesthetic presentation and intuitive operational logic.

[0007] In one embodiment, the first button body includes an extension and a button. The button is disposed on the extension, and two first locking blocks are disposed on the extension. The button abuts against the spring-loaded component, and the two adjacent extensions cooperate to form an installation space. By directly abutting the button against the spring-loaded component, it becomes the core contact point for force transmission. This design allows the force of the pressing action to be precisely applied to the spring-loaded component, ensuring that each press stably triggers the deformation of the spring-loaded component. At the same time, the elastic potential energy of the spring-loaded component allows for rapid reset, ensuring sensitive feedback and consistency of button operation and enhancing the tactile feel similar to piano keys. The two first locking blocks on the extension can securely position the entire first button body by engaging with the housing assembly, preventing loosening due to frequent button pressing. More importantly, the adjacent extensions cooperate to form an installation space, providing a suitable basis for the precise embedding of the second button. This makes the layout of the first and second buttons more consistent with the arrangement logic of the black and white keys of a piano, ensuring the compactness of the overall structure and making the button distribution more regular, facilitating users to quickly identify different function buttons.

[0008] In one embodiment, the first button further includes a first positioning member, which is disposed on the button body and abuts against the housing assembly through the circuit board assembly. By disposing the first positioning member on the button and abutting against the housing assembly through the circuit board assembly, the movement trajectory of the button can be constrained. When the user presses the button, the first positioning member passes through the circuit board assembly along its own axis, forming a stable support point with the housing assembly, effectively preventing the button from shifting or tilting laterally due to uneven force, ensuring that the button always acts accurately on the rebound member in a preset direction, further improving the accuracy and consistency of the pressing operation, and ensuring that each trigger can stably correspond to the signal output area of ​​the circuit board assembly. Moreover, it strengthens the connection between the button, the housing assembly, and the circuit board assembly. The portion of the first positioning member passing through the circuit board assembly can form a gap fit with the circuit board assembly, which does not affect the normal movement of the button, but also limits the shaking of the circuit board assembly to a certain extent, so that the three form a stable whole that restrains each other, reducing the risk of functional failure due to component loosening after long-term use, and extending the service life of the piano-style control button.

[0009] In one embodiment, the cross-sectional area of ​​the extension is smaller than that of the button. This structural design, where the extension's cross-sectional area is smaller than the button's, lays the foundation for creating an installation space to accommodate the second button. Its slim structure reduces the space occupied between adjacent extensions, ensuring dimensional accuracy of the installation space, allowing for a tighter fit between the second button and the installation space, preventing loosening or misalignment, and simultaneously making the overall button layout more compact, integrating more function buttons within a limited housing assembly.

[0010] In one embodiment, the extension and the button are integrally formed. By integrally forming the extension and the button, the connection gap between the extension and the button is eliminated, making them a seamless whole that can more evenly withstand the impact force during pressing. When the pressing force is transmitted from the button to the extension, there is no stress concentration due to weak points at the joint, effectively avoiding potential breakage and loosening problems after long-term use, and significantly improving the durability of the first button body.

[0011] In one embodiment, the second button includes a second button body, a second locking block, and a second positioning member. One end of the second button body contacts the spring-loaded component. The second button body is disposed opposite to the circuit board assembly and located in the mounting space. The second positioning member is disposed on the button body and near the contact end between the second button body and the spring-loaded component. The second positioning member passes through the circuit board assembly and abuts against the housing assembly. There are two second locking blocks, each disposed on the button body and away from the end of the second button body that contacts the spring-loaded component. The two second locking blocks are engaged with the housing assembly. By having one end of the second button body contact the spring-loaded component and being disposed opposite to the circuit board assembly, a complete force transmission and signal triggering path is constructed. Its layout within the mounting space forms a staggered arrangement similar to the black and white keys of a piano with the first button, which not only makes full use of the space of the housing assembly but also makes the button distribution more regular, facilitating users to quickly identify different functional areas. When the second button is pressed, the force causes the spring-loaded component to deform, simultaneously triggering a signal response from the circuit board assembly, enabling precise control of the appliance or screen. The elastic restoring force of the spring-loaded component then pushes the button back to its original position, ensuring continuous operation. Two second locking blocks are located at the end furthest from the spring-loaded component and are engaged with the housing assembly, forming a stable end-fixing structure. This design effectively limits the displacement of the second button, preventing excessive shaking or detachment during pressing or rebound. Combined with lateral limiting of the installation space, this ensures precise positioning of the second button, improving long-term structural stability. The second positioning component passes through the circuit board assembly and abuts against the housing assembly, further enhancing the button's motion guidance and ensuring that the pressing trajectory of the second button remains straight, avoiding skewness or jamming. This allows each press to precisely target the corresponding area of ​​the spring-loaded component and the circuit board assembly, reducing signal triggering errors.

[0012] In one embodiment, the spring mechanism includes a spring base and a spring body. The spring base is disposed on the housing assembly, and the spring body is disposed on the spring base. The spring body contacts the first button and the second button. By fixing the spring base to the housing assembly, serving as the basic support structure for the entire spring mechanism, its stable installation ensures that the spring body will not shift or wobble when subjected to force deformation. This fixing method provides a rigid fulcrum for the spring body, ensuring that the elastic deformation of the spring body is always within a preset range. This avoids unstable spring force due to loosening of the spring base, thereby ensuring consistent reset effect after each press of the first and second buttons, enhancing the regularity and predictability of operation. The spring body directly contacts the first and second buttons and is the core component for realizing the spring function. When a button is pressed, the spring body undergoes elastic deformation under force, converting the mechanical energy of the press into elastic potential energy; after the button is released, the elastic potential energy is released, pushing the button to quickly reset.

[0013] In one embodiment, the housing assembly includes a housing body and a fixing component. The fixing component is disposed on the housing body, and portions of the first button and the second button are disposed on the fixing component, abutting against the housing body. The circuit board assembly is disposed on the housing body. By placing the circuit board assembly on the housing body, a stable mounting platform is provided for the circuit board assembly, ensuring that it will not shift due to vibration or external force during long-term use, thereby guaranteeing the stability of signal transmission between the button and the circuit board. Simultaneously, the abutting between the housing body and portions of the first and second buttons forms an auxiliary limiting structure, preventing excessive tilting or detachment of the buttons during pressing, further improving operational reliability. The fixing component, disposed on the housing body, provides precise positioning specifically for the installation requirements of the first and second buttons. Its partial structural cooperation with the buttons not only secures the key force points of the buttons through a snap-fit ​​mechanism but also provides necessary space for button movement.

[0014] In one embodiment, the housing body includes a bottom shell and side shells. The side shells are disposed on and surround the bottom shell, the fixing component is disposed on the bottom shell, portions of the first button and the second button abut against the bottom shell, and the circuit board assembly is disposed on the bottom shell. By utilizing the bottom shell, its flat surface provides a stable mounting reference for the circuit board assembly, ensuring the accuracy of circuit component arrangement and the stability of signal transmission. After the fixing component is installed on the bottom shell, the rigid support of the bottom shell enhances the positioning effect of the buttons, preventing button displacement due to loose foundation. Furthermore, the abutting structure between the bottom shell and the buttons, combined with the limiting effect of the fixing component, creates a three-dimensional protective space around the bottom shell, enclosing the fixing component and circuit board assembly, among other core components. This surrounding structure effectively prevents the intrusion of external dust, liquids, or foreign objects, protecting internal components from contamination or impact damage.

[0015] In one embodiment, the fixing assembly includes a fixing base plate and fixing members. The fixing base plate is disposed on the housing body, and the number of fixing members is twice the number of the first button and the second button. Multiple fixing members are disposed on the fixing base plate, and portions of the first button and the second button are engaged with the fixing members. The fixing base plate, mounted on the bottom shell, serves as the load-bearing foundation for the fixing members. Its flat surface provides a uniform installation reference for the multiple fixing members, ensuring that the height and spacing of all fixing members remain consistent, laying the foundation for the neat arrangement of the buttons. Simultaneously, the fixing base plate connects the dispersed fixing members into a whole, enhancing the rigidity of the fixing structure and preventing individual fixing members from deforming due to excessive force, thus improving the long-term fixing effect on the buttons. The number of fixing members is twice the number of the first button and the second button; this paired arrangement allows for symmetrical clamping of individual buttons from both sides. This symmetrical clamping structure reduces the installation position error of the buttons, ensuring that the pressing trajectory of each button remains consistent, reducing operational stuttering or signal triggering errors caused by positioning deviations.

[0016] In one embodiment, the system further includes magnetic components and a connecting housing. Multiple magnetic components are disposed on the housing assembly and located on the side of the housing assembly away from the circuit board assembly. The connecting housing is disposed on the housing assembly and magnetically connected to the multiple magnetic components. The connecting housing is used for connection to an external structure. By placing multiple magnetic components on the side of the housing assembly away from the circuit board assembly, a stable magnetic connection is formed with the connecting housing. This connection method eliminates the need for complex mechanical clips or screws. Simply fixing the connecting housing to the external structure allows for quick assembly of the housing assembly and the external structure, facilitating subsequent disassembly and maintenance. The tightness of the magnetic adsorption ensures a secure connection, preventing separation due to vibration or collision during use. It also reduces component wear associated with traditional connection methods, extending the overall structure's service life.

[0017] In one embodiment, the connecting housing includes a connecting housing body and connectors. The connecting housing body is disposed on the housing assembly and magnetically connected to a plurality of magnetic components. The plurality of connectors are disposed on the connecting housing body and are used for connection to an external structure. The precise adsorption and engagement of the connecting housing body with the plurality of magnetic components ensures the stability of the connection to the housing assembly. The structural design of the connecting housing body can be adapted to the distribution of the magnetic components, enhancing the magnetic adsorption force through large-area contact and preventing loosening due to uneven local force. The multiple connectors disposed on the connecting housing body realize the connection function with the external structure. Attached Figure Description

[0036] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0038] The piano-style control buttons of some embodiments of this utility model are described below with reference to the accompanying drawings.

[0039] Example

[0040] like Figures 1 to 10As shown, this embodiment discloses a piano-style control button, including: a housing assembly 1; multiple first buttons 2, which are arranged adjacently on the housing assembly 1, with portions of the adjacent first buttons 2 cooperating to form mounting spaces 201; multiple second buttons 3, which are arranged spaced apart on the housing assembly 1, with each of the multiple second buttons 3 corresponding to one of the mounting spaces 201; a circuit board assembly 4, which is disposed on the housing assembly 1; and multiple spring-loaded elements 5, with portions of each spring-loaded element 5 correspondingly sandwiched between the multiple first buttons 2 and the circuit board assembly 4, and other portions of each spring-loaded element 5 correspondingly sandwiched between the multiple second buttons 3 and the circuit board assembly 4, and the multiple spring-loaded elements 5 being electrically connected to the circuit board assembly 4.

[0041] This application discloses a piano-style control button, employing a combination design of multiple first buttons 2 and multiple second buttons 3. This design not only replicates the classic black and white key layout of a piano but also achieves a compact layout through the corresponding fit of the installation space 201. Multiple control buttons are efficiently integrated within the limited space of the housing component 1, meeting the multi-level operation needs of appliances or screens. The spring-loaded component 5 forms a stable elastic support between the first buttons 2, second buttons 3, and the circuit board component 4. When pressed, it quickly pushes the buttons back to their original position, ensuring rapid operation response and simulating the tactile feel of piano keys. Combined with the piano tone emitted when the buttons are triggered, this transforms the tedious process of controlling appliances into a fun and interactive experience, especially suitable for enhancing user enjoyment in home settings. The corresponding trigger structure between the circuit board component 4 and the buttons ensures stable signal transmission with each press, enabling precise control of appliance switching, mode adjustment, or screen interaction. This innovative design, combining musical instrument aesthetics with practical control functions, breaks through the monotonous experience of traditional buttons while also considering the durability and functionality of industrial products.

[0042] like Figure 1 , Figure 3 , Figure 7 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first button 2 includes a first button body 21 and a first locking block 22. One end of the first button body 21 contacts the spring-loaded member 5. The first button body 21 is disposed opposite to the circuit board assembly 4. There are two first locking blocks 22, which are disposed on the first button body 21 and located away from the end of the first button body 21 that contacts the spring-loaded member 5. The two first locking blocks 22 are locked in the housing assembly 1. Two adjacent first button bodies 21 cooperate to form an installation space 201. By contacting one end of the first button body 21 with the spring-loaded member 5 and being disposed opposite to the circuit board assembly 4, when the first button body 21 is pressed, it can directly act on the spring-loaded member 5 to deform it, and at the same time transmit a trigger signal to the circuit board assembly 4, ensuring that the pressing operation is quickly converted into an electrical signal output, providing a reliable command source for electrical appliances or screen control. The elastic restoring force of the spring-loaded member 5 can also efficiently push the button to reset through contact with the first button body 21, ensuring the continuity of operation. Two first locking blocks 22 are located at the end of the first key body 31 furthest from the return element 5 and are engaged with the housing assembly 1, forming a stable installation and positioning structure. This engaging method not only firmly fixes the first key body 21 to the housing assembly 1, preventing it from shifting or shaking during pressing or rebounding, but also restricts the movement trajectory of the key, ensuring that each press is performed in a preset direction, thus improving the accuracy of operation and the durability of the structure. In addition, the two adjacent first key bodies 21 cooperate to form an installation space 201, a design that reflects the synergy of the structure. The installation space 201 and the second key 3 are matched one-to-one, which not only makes full use of the gap between adjacent first keys 2, achieving a compact and efficient key layout, but also, through the orderly arrangement of the first keys 2 and the second keys 3, further replicates the classic distribution of the black and white keys of a piano, laying the foundation for the aesthetic presentation of the overall structure and the intuitiveness of the operating logic.

[0043] like Figure 3 , Figure 7 , Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the first button body 21 includes an extension member 211 and a button 212. The button 212 is disposed on the extension member 211, and two first locking blocks 22 are disposed on the extension member 211. The button 212 abuts against the spring member 5, and the two adjacent extension members 211 cooperate to form an installation space 201. By directly abutting the button 212 against the spring member 5, it becomes the core contact point for force transmission. This design allows the force of the pressing action to be accurately applied to the spring member 5, ensuring that the deformation of the spring member 5 is stably triggered each time it is pressed. At the same time, the elastic potential energy of the spring member 5 is used to quickly reset, ensuring the sensitive feedback and consistency of the button 212 operation and enhancing the pressing feel similar to piano keys. The two first locking blocks 22 disposed on the extension member 211 can securely position the entire first button body 21 by engaging with the housing assembly 1, preventing loosening due to frequent button pressing. More importantly, the adjacent extension pieces 211 cooperate to form an installation space 201, providing a suitable basis for the precise embedding of the second button 3. This makes the layout of the first button 2 and the second button 3 more in line with the arrangement logic of the black and white keys of a piano, ensuring the compactness of the overall structure and making the button distribution more regular, which makes it easier for users to quickly identify different function buttons.

[0044] like Figure 7 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first button 2 also includes a first positioning member 23, which is disposed on the button 212 of the first button body 21, and the first positioning member 23 passes through the circuit board assembly 4 and abuts against the housing assembly 1. By disposing the first positioning member 23 on the button 212 and passing through the circuit board assembly 4 and abutting against the housing assembly 1, the movement trajectory of the button 212 can be constrained. When the user presses the button 212, the first positioning member 23 passes through the circuit board assembly 4 along its own axis and forms a stable support point with the housing assembly 1, effectively preventing the button from shifting or tilting laterally due to uneven force, ensuring that the button 212 always acts accurately on the rebound member 5 in a preset direction, further improving the accuracy and consistency of the pressing operation, and ensuring that each trigger can stably correspond to the signal output area of ​​the circuit board assembly 4. Moreover, it strengthens the connection between the button 212 and the housing assembly 1 and the circuit board assembly 4. The portion of the first positioning member 23 that passes through the circuit board assembly 4 can form a clearance fit with the circuit board assembly 4, which not only does not affect the normal operation of the button 212, but also restricts the shaking of the circuit board assembly 4 to a certain extent, so that the three form a stable whole that restrains each other, reducing the risk of functional failure due to loose parts after long-term use and extending the service life of the piano-style control buttons.

[0045] like Figure 8 and Figure 9As shown, in addition to the features of the above embodiments, this embodiment further specifies that the cross-sectional area of ​​the extension member 211 is smaller than the cross-sectional area of ​​the button 212. By utilizing the structural design that the cross-sectional area of ​​the extension member 211 is smaller than that of the button 212, a foundation is laid for forming the mounting space 201 to accommodate the second button 3. Its slender structure reduces the occupation of the gap between adjacent extension members 211, ensuring the dimensional accuracy of the mounting space, making the fit between the second button 3 and the mounting space 201 tighter, avoiding loosening or misalignment, and at the same time making the overall button layout more compact, integrating more function buttons within the limited housing assembly 1.

[0046] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the extension member 211 and the button 212 are integrally formed. By integrally forming the extension member 211 and the button 212, the connection gap between the extension member 211 and the button 212 is eliminated, making the two form a seamless whole, which can more evenly bear the impact force when pressed. When the pressing force is transmitted from the button 212 to the extension member 211, there will be no stress concentration due to the weak point at the splice, effectively avoiding the breakage and loosening problems that may occur after long-term use, and significantly improving the durability of the first button body 21.

[0047] like Figure 1 , Figure 3 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the second button 3 includes a second button body 31, a second locking block 32, and a second positioning member 33. One end of the second button body 31 contacts the spring-loaded member 5. The second button body 31 is disposed opposite to the circuit board assembly 4 and is located at the mounting space 201. The second positioning member 33 is disposed on the button body 31 and close to the contact end between the second button body 31 and the spring-loaded member 5. The second positioning member 33 passes through the circuit board assembly 4 and abuts against the housing assembly 1. There are two second locking blocks 32, which are disposed on the button body 31 and away from the end of the second button body 31 that contacts the spring-loaded member 5. The two second locking blocks 32 are locked in the housing assembly 1. By having one end of the second button body 31 contact the spring-loaded member 5 and be disposed opposite to the circuit board assembly 4, a complete force transmission and signal triggering path is constructed. Its layout within the installation space 201, together with the first button 2, forms a staggered arrangement similar to the black and white keys of a piano. This fully utilizes the space of the housing assembly 1 and makes the button distribution more regular, facilitating quick identification of different functional areas by the user. When the second button body 31 is pressed, the force pushes the return element 5 to deform, simultaneously triggering a signal response from the circuit board assembly 4, enabling precise control of the appliance or screen. The elastic restoring force of the return element 5 pushes the body back to its original position, ensuring continuous operation. Two second locking blocks 32 are located at the end furthest from the return element 5 and are engaged with the housing assembly 1, forming a stable end fixing structure. This design effectively limits the displacement of the second button body 31, preventing excessive shaking or detachment during pressing or rebound. Combined with the lateral limiting of the installation space 201, this ensures the second button 3 maintains precise positioning, improving the structural stability for long-term use. The second positioning element 33 passes through the circuit board assembly 4 and abuts against the housing assembly 1, further enhancing the motion guidance of the button and ensuring that the pressing trajectory of the second button body 31 always remains straight, avoiding skewness or jamming, so that each press can accurately act on the corresponding area of ​​the rebound element 5 and the circuit board assembly 4, reducing signal triggering errors.

[0048] like Figure 3 and Figure 5As shown, in addition to the features of the above embodiments, this embodiment further defines the following: the spring-loaded component 5 includes a spring-loaded base 51 and a spring-loaded body 52. ​​The spring-loaded base 51 is disposed on the housing assembly 1, and the spring-loaded body 52 is disposed on the spring-loaded base 51. The spring-loaded body 52 is in contact with the first button 2 and the second button 3. By fixing the spring-loaded base 51 to the housing assembly 1 as the basic support structure of the entire spring-loaded component 5, its stable installation method ensures that the spring-loaded body 52 will not shift or shake when subjected to force deformation. This fixing method provides a rigid fulcrum for the spring-loaded body 52, so that the elastic deformation of the spring-loaded body 52 is always within a preset range, avoiding unstable spring force due to loosening of the spring-loaded base 51, thereby ensuring that the reset effect of the first button 2 and the second button 3 is consistent after each press, and enhancing the regularity and predictability of operation. The spring-loaded body 52 is in direct contact with the first button 2 and the second button 3, and is the core component for realizing the spring-loaded function. When the button is pressed, the rebound body 52 undergoes elastic deformation under force, converting the mechanical energy of the press into elastic potential energy; after the button is released, the elastic potential energy is released, pushing the button to quickly reset.

[0049] like Figure 1 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing assembly 1 includes a housing body 11 and a fixing assembly 12. The fixing assembly 12 is disposed on the housing body 11, and portions of the first button 2 and the second button 3 are disposed on the fixing assembly 12, with portions of the first button 2 and the second button 3 abutting against the housing body 11. The circuit board assembly 4 is disposed on the housing body 11. By disposing of the circuit board assembly 4 on the housing body 11, a stable mounting platform is provided for the circuit board assembly 4, ensuring that it will not shift due to vibration or external force during long-term use, thereby ensuring the stability of signal transmission between the button and the circuit board. At the same time, the abutting between the housing body 11 and portions of the first button 2 and the second button 3 forms an auxiliary limiting structure, preventing the buttons from tilting excessively or falling off during pressing, further improving the reliability of operation. The fixing assembly 12 is disposed on the housing body 11 and provides precise positioning specifically for the installation requirements of the first button 2 and the second button 3. Its partial structure cooperates with the buttons, both fixing the key force points of the buttons through a snap-fit ​​method and reserving the necessary space for the buttons to move.

[0050] like Figure 5 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further defines: the housing body 11 includes a bottom shell 111 and a side shell 112. The side shell 112 is disposed on and surrounds the bottom shell 111. The fixing component 12 is disposed on the bottom shell 111. The first button 2 and the second button 3 partially abut against the bottom shell 111. The circuit board assembly 4 is disposed on the bottom shell 111. By utilizing the bottom shell 111, its flat surface provides a stable mounting reference for the circuit board assembly 4, ensuring the layout accuracy of circuit components and the stability of signal transmission. After the fixing component 12 is installed on the bottom shell 111, the rigid support of the bottom shell 111 can enhance the positioning effect of the buttons and prevent the buttons from shifting due to loose foundation. In addition, the abutting structure between the bottom shell 111 and the buttons, together with the limiting function of the fixing component 12, creates a three-dimensional protective space around the bottom shell 111, enclosing the fixing component 12 and the circuit board assembly 4 and other core components on the bottom shell 111. This wraparound structure effectively blocks external dust, liquids, or foreign objects from entering, protecting internal components from contamination or impact damage.

[0051] like Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further defines: the fixing component 12 includes a fixing base plate 121 and fixing members 122. The fixing base plate 121 is disposed on the housing body 11. The number of fixing members 122 is twice the number of the first button 2 and the second button 3. Multiple fixing members 122 are disposed on the fixing base plate 121, and parts of the first button 2 and the second button 3 are engaged with the fixing members 122. The fixing base plate 121 is installed on the bottom shell 111, serving as the bearing base for the fixing members 122. Its flat surface provides a uniform installation reference for the multiple fixing members 122, ensuring that the height and spacing of all fixing members 122 are consistent, laying the foundation for the neat arrangement of the buttons. At the same time, the fixing base plate 121 connects the dispersed fixing members 122 into a whole, enhancing the rigidity of the fixing structure, preventing individual fixing members 122 from deforming due to excessive force, and improving the long-term fixing effect of the buttons. The number of fixing members 122 is twice the number of the first button 2 and the second button 3. This paired arrangement can form a symmetrical clamping of individual buttons from both sides. This symmetrical clamping structure reduces the installation position error of the buttons, ensuring that the pressing trajectory of each button is consistent and reducing operation lag or signal triggering errors caused by positioning deviation.

[0052] like Figure 2 , Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further includes: a magnetic component 6 and a connecting housing 7. The magnetic component 6 is multiple, disposed on the housing assembly 1 and located on the side of the housing assembly 1 away from the circuit board assembly 4. The connecting housing 7 is disposed on the housing assembly 1 and magnetically connected to the multiple magnetic components 6. The connecting housing 7 is used for connection to an external structure. By disposing of the multiple magnetic components 6 on the side of the housing assembly 1 away from the circuit board assembly 4, a stable magnetic connection is formed with the connecting housing 7. This connection method eliminates the need for complex mechanical clips or screws. Simply fixing the connecting housing 7 to the external structure allows for quick assembly of the housing assembly 1 and the external structure, facilitating subsequent disassembly and maintenance. The tightness of the magnetic adsorption ensures a secure connection, preventing separation due to vibration or collision during use, while also reducing component wear caused by traditional connection methods and extending the overall structure's service life.

[0053] like Figure 2 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines: the connecting shell 7 includes a connecting shell body 71 and connecting members 72. The connecting shell body 71 is disposed on the shell assembly 1 and magnetically connected to multiple magnetic members 6. Multiple connecting members 72 are disposed on the connecting shell body 71 and are used for connection to external structures. By precisely adsorbing and engaging the connecting shell body 72 with the multiple magnetic members 6, the stability of the connection to the shell assembly 1 is ensured. The structural design of the connecting shell body 72 can adapt to the distribution position of the magnetic members 6, enhancing the magnetic adsorption force through large-area contact and avoiding loosening of the connection due to uneven local force. The multiple connecting members 72 disposed on the connecting shell body 71 realize the connection function with external structures.

[0054] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
