Description

Technical Field

[0001] This utility model relates to the field of switch button technology, and more specifically, to a switch button with multiple triggering modes. Background Technology

[0002] In the current field of button technology, the traditional implementation of multi-function buttons mainly relies on two types: push rods or rocker buttons. They have certain characteristics in terms of function triggering, but they also have obvious limitations.

[0003] From a functional triggering perspective, both push-button and rocker buttons can achieve two functions using a single button structure. Taking common electronic devices as an example, on some small remote controls, a push-button might switch channels and adjust volume by pushing it forward or backward; while a rocker button on some simple electrical switches can control the device's on / off state and switch between different modes by pressing it up and down or tossing it left and right. This design, where a single button achieves dual functions, improves operational efficiency and space utilization to some extent. However, when it's necessary to further expand the button's functionality, the traditional design reveals serious shortcomings. Due to the inherent characteristics of its structure, adding new functions necessitates increasing the number of buttons. Utility Model Content

[0004] This specification provides a multi-trigger type switch button to overcome at least one technical problem existing in related technologies.

[0005] According to the embodiments of this specification, a multi-trigger switch button is provided, including: The device comprises a button, an upper shell, a silicone pad, a printed circuit board assembly, and a lower shell; wherein, the upper shell has a button mounting hole, the button is embedded in the button mounting hole, and the button can move relative to the upper shell in the vertical direction; the main body of the upper shell is a square structure, and its lower part has an internal space for accommodating the silicone pad and the printed circuit board assembly, the printed circuit board assembly being located below the silicone pad; The upper end of the silicone pad is provided with multiple sets of protruding silicone keys, each set of silicone keys is distributed on both sides of the silicone pad, and each set of silicone keys corresponds to an independent circuit contact on the printed circuit board assembly. Silicone key extrusion plates are integrally provided on both sides of the bottom of the key. The button is connected to the corresponding rotating part of the upper shell through the rotating shafts on both sides to form a rotating pair. When the button is rotated, the silicone key extrusion plate on either side extrudes the silicone key on the corresponding side, triggering the silicone key on that side to conduct with the corresponding circuit contact on the printed circuit board assembly. The lower shell is detachably connected to the upper shell.

[0006] In some optional embodiments, the upper end of the silicone pad is provided with a protruding first silicone key, a second silicone key, a third silicone key and a fourth silicone key, wherein the first silicone key and the second silicone key are located on one side, and the third silicone key and the fourth silicone key are located on the other side; A first silicone key extrusion plate is integrally provided on the bottom of the first side of the button, and a second silicone key extrusion plate is integrally provided on the bottom of the second side of the button opposite to the first side. The first silicone key extrusion plate and the second silicone key extrusion plate are used to extrude two silicone keys on the corresponding sides, respectively.

[0007] In some alternative embodiments, along the downward pressing direction of the button, the travel of the silicone key is less than the limiting travel of the lower end of the rotating shaft mating part on the button.

[0008] In some alternative implementations, the button and the silicone pad have a preset pre-pressure amount in the vertical direction.

[0009] In some optional embodiments, the button includes a button cap, a first pivot is integrally provided at the bottom center of the third side of the button cap, and a second pivot is integrally provided at the bottom center of the fourth side opposite to the third side. The rotating shaft mating part includes a first rotating shaft mounting hole and a second rotating shaft mounting hole, wherein the first rotating shaft mounting hole is used to accommodate the first rotating shaft, and the second rotating shaft mounting hole is used to accommodate the second rotating shaft.

[0010] In some alternative embodiments, the lower shell and the upper shell are assembled by a snap-fit ​​structure.

[0011] In some optional embodiments, a plurality of first screw posts are provided on both sides of the upper end of the silicone pad, and screw holes are provided on the printed circuit board assembly at positions corresponding to the first screw posts. Second screw posts are provided in the lower housing at positions corresponding to the screw holes on the printed circuit board assembly. The first screw posts, screw holes and second screw posts at corresponding positions are tightened by screws.

[0012] In some alternative implementations, the button is made of engineering plastic, and the top of the button is integrally provided with ribs.

[0013] In some optional embodiments, a first protrusion is integrally provided at the middle position of the side end of the first silicone key extrusion plate, and a second protrusion is integrally provided at the middle position of the side end of the second silicone key extrusion plate. The upper shell has a first protrusion limiting groove near the first protrusion and a second protrusion limiting groove near the second protrusion. The first protrusion limiting groove abuts against the first protrusion when the button is rotated to a predetermined angle in a first direction, thereby limiting the rotation range of the button in the first direction. The second protrusion limiting groove abuts against the second protrusion when the button is rotated to a predetermined angle in a second direction, thereby limiting the rotation range of the button in the second direction.

[0014] In some optional embodiments, the rotational movement of the button includes rotation in a clockwise direction and a counterclockwise direction; wherein, when the button rotates clockwise, the silicone button pressing plate on its first side presses the silicone button on the corresponding side of the middle region of the silicone pad, triggering the circuit contact corresponding to the silicone button on that corresponding side to conduct, thereby realizing a first function; when the button rotates counterclockwise, the silicone button pressing plate on its second side presses the silicone button on the other corresponding side of the middle region of the silicone pad, triggering the circuit contact corresponding to the silicone button on that other corresponding side to conduct, thereby realizing a second function; When the button is pressed down, multiple sets of protruding silicone keys are squeezed simultaneously, triggering the circuit contacts corresponding to all silicone keys to conduct, thus realizing the third function.

[0015] The technical solution of this application has several significant technical advantages, as detailed below: 1. The technical solution of this application realizes three triggering modes on a single button, effectively overcoming the drawback of needing to increase the number of buttons to expand the functions of traditional push rods or rocker buttons. Within a limited space, the button can trigger different functions by pushing it left and right, and can also achieve other functions such as circuit conduction by pressing it down, improving space utilization and avoiding the problems of crowded hardware layout and increased overall switch size caused by adding buttons, making the internal structure of the device more compact and concise.

[0016] 2. The pre-pressed pressure between the button and the silicone pad provides clear tactile feedback to the user without affecting the normal movement of the button. When the user presses or rotates the button, they can clearly feel the appropriate resistance and elasticity, making the operation more layered and accurate, and improving the convenience and comfort of the user.

[0017] 3. The upper and lower shells utilize a snap-fit ​​structure and screws to secure the silicone pads and printed circuit board assemblies, creating a robust overall frame. This ensures that the components maintain stable relative positions even under vibration, impact, or frequent operation, effectively preventing displacement or loosening. Furthermore, the design of the mating parts between the pivots on both sides of the buttons and the pivot of the upper shell, along with the limiting structure of the protrusions and limiting grooves, guarantees the smoothness and accuracy of button rotation. This prevents damage to the internal structure from excessive rotation or shaking, extending product lifespan and reducing maintenance costs.

[0018] 4. During button press operation, the design of the protruding limiting groove and the upper shell's limiting stroke ensures that when subjected to large external forces, the force is reasonably distributed, preventing it from being entirely applied to the printed circuit board assembly and effectively protecting the circuit components from damage. The design of multiple silicone buttons on the silicone pad allows the function to be activated by just one silicone button, improving the fault tolerance and stability of function triggering, reducing the risk of functional failure due to the malfunction of a single silicone button, and ensuring stable operation of the switch button under various environmental and usage conditions, maintaining the normal operation of the equipment.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0026] Currently, multi-function buttons are mainly implemented using push rods or rocker buttons, such as... Figure 1 and Figure 2 As shown, both types of switches can use a single button structure to trigger two functions. However, to add other functions, the only way is to increase the number of buttons. The push-button assembly typically involves pivots on both sides of the button, which, after mating with a matching component (the "matching component" refers to the part that cooperates with the push-button during assembly), enable rotation. However, the drawback of this structure is that the button cannot move up and down.

[0027] This application provides a multi-trigger switch button that can simultaneously provide vertical travel while allowing for button rotation, thereby increasing the button's functionality per unit area.

Figure 13 right Figure 3 The diagram illustrates the application scenarios of the multi-trigger switch buttons provided in the diagram.

[0029] The switch button includes a button 1, an upper shell 2, a silicone pad 3, a printed circuit board assembly 4, and a lower shell 5. The upper shell 2 has a button mounting hole 205, in which the button 1 is embedded. The button 1 can move relative to the upper shell 2 in the vertical direction. The upper shell 2 has a square structure, with an internal space at its lower part to accommodate the silicone pad 3 and the printed circuit board assembly 4, which is located below the silicone pad 3. The upper end of the silicone pad 3 has multiple sets of protruding silicone keys, distributed on both sides of the central area of ​​the silicone pad 3, and each set of silicone keys corresponds to an independent circuit contact on the printed circuit board assembly 4. Silicone key pressing plates are integrally formed on both sides of the bottom of the button 1. The button 1 forms a rotating pair by engaging with the corresponding rotating shaft parts of the upper shell 2 via rotating shafts on both sides. When the button 1 rotates, the silicone key pressing plate on either side presses the corresponding silicone key, triggering the silicone key on that side to conduct with the corresponding circuit contact on the printed circuit board assembly 4. The lower shell 5 is detachably connected to the upper shell 2. The lower shell 5 is used to protect the internal structure and provide an installation interface. It is detachably connected to the upper shell 2. The detachable connection design makes it easy to repair, replace or upgrade the internal components of the switch button. When it is necessary to inspect or repair the internal silicone pad 3, printed circuit board assembly 4, etc., the lower shell 5 can be easily separated from the upper shell 2 and reconnected after the operation is completed.

[0030] In the technical solution of this application embodiment, the rotating shafts on both sides of the button 1 form a rotating pair with the upper shell 2, such as... Figure 13 As shown, when a horizontal thrust is applied to button 1 in a certain direction, according to the rotational law of rigid bodies, this thrust will generate a torque relative to the axis of rotation. For example, if the thrust is applied to the upper edge of button 1 and perpendicular to the line connecting the axis of rotation and that edge, according to the principle that torque equals force multiplied by the lever arm, a torque will be generated that causes button 1 to rotate around the axis of rotation, thereby driving button 1 to rotate. The constraint of the upper shell 2 on the axis of rotation and the restriction of the overall space of button 1 effectively prevent button 1 from displacing in other directions or moving irregularly when subjected to a horizontal thrust, ensuring that it rotates stably around the axis of rotation, thereby achieving the corresponding function triggering and a good operating feel.

[0031] Meanwhile, the upper end of the silicone pad 3 is provided with multiple sets of protruding silicone keys, each set distributed on both sides of the silicone pad 3. Each set of silicone keys corresponds to an independent circuit contact on the printed circuit board assembly 4. When button 1 is pressed down, each of these protruding silicone keys is pressed simultaneously. Due to the elasticity of the silicone keys, after being deformed by button 1, they come into contact with the printed circuit board assembly 4 below. The printed circuit board assembly 4 is provided with circuit contacts corresponding to the silicone keys. After the silicone keys deform, they come into contact with these contacts, thereby changing the circuit state, completing circuit conduction, realizing signal transmission, and triggering corresponding circuit functions, such as device confirmation, start-up, and other operations.

[0032] In this application's technical solution, button 1 integrates both rotation and pressing functions. It is connected to the upper shell's rotating shaft via two side pivots, allowing it to rotate around the pivot. Simultaneously, the button can slide vertically. That is, button 1 can be triggered by rotation (clockwise and counterclockwise rotation) and by pressing. Specifically, the user can push button 1 back and forth, causing it to rotate around the pivot. The bottom pressing plate then presses down on the corresponding silicone button, triggering the circuitry of the printed circuit board (e.g., switching functions). Alternatively, the user can press button 1, causing all the silicone buttons to simultaneously contact the printed circuit board contacts, triggering the corresponding function (e.g., confirming an operation).

[0033] To ensure the stability and reliability of button 1 during rotation, the diameter and length of the rotating shafts on both sides of button 1, as well as the dimensions of the mating parts of the upper shell 2 that accommodate the rotating shafts, require precise design and strict tolerance control during the design phase. For example, a reasonable clearance fit can be adopted; if the rotating shaft diameter is designed to be 5mm, the corresponding hole diameter in the upper shell 2 can be controlled between 5.05mm and 5.1mm. This ensures both the flexibility of the rotating shaft's rotation and a relatively stable connection, preventing wobbling or jamming during rotation due to dimensional deviations.

[0034] This application's technical solution implements three triggering methods on a single button, effectively overcoming the drawback of traditional push-button or rocker button functions requiring an increase in the number of buttons for expansion. Within a limited space, the button can trigger different functions by pushing left and right, and can also achieve other functions such as circuit conduction by pressing down, improving space utilization and avoiding the problems of crowded hardware layout and increased overall switch size caused by adding buttons, making the internal structure of the device more compact and concise.

[0035] In an optional embodiment, the upper end of the silicone pad 3 is provided with a protruding first silicone key 302, a second silicone key 303, a third silicone key 304, and a fourth silicone key 305, wherein the first silicone key 302 and the second silicone key 303 are located on one side, and the third silicone key 304 and the fourth silicone key 305 are located on the other side; a first silicone key extrusion plate 104 is integrally provided on the bottom of the first side of the button 1, and a second silicone key extrusion plate is integrally provided on the bottom of the second side of the button 1 opposite to the first side; the first silicone key extrusion plate 104 and the second silicone key extrusion plate are respectively used to extrude the two silicone keys on the corresponding sides.

[0036] In this embodiment, the upper end of the silicone pad 3 is provided with four silicone keys, which are symmetrically distributed in two groups. The first group (which may include the first silicone key 302 and the second silicone key 303) may be located on the left side of the silicone pad 3. The second group (which includes the third silicone key 304 and the fourth silicone key 305) may be located on the right side of the silicone pad. After the silicone keys are deformed by pressure, they contact the contacts of the printed circuit board assembly 4 to realize circuit conduction. Each group of silicone keys corresponds to an independent circuit contact on the printed circuit board assembly 4 to achieve functional isolation.

[0037] The rotation triggering principle of button 1 in this embodiment is explained below. The motion transmission path is as follows: the user pushes button 1 → the button rotates around the axis → the extrusion plate moves accordingly → the corresponding silicone key is extruded → the silicone key is compressed and deformed → the trigger circuit function is activated. For example, when button 1 is pushed to the right, the left extrusion plate 104 presses down the first set of silicone keys 302 and 303; when button 1 is pushed to the left, the right extrusion plate presses down the second set of silicone keys 304 and 305.

[0038] In an optional embodiment, along the downward pressing direction of button 1, the travel of the silicone key is less than the limiting travel of the lower end of the rotating shaft mating part on button 1.

[0039] In this embodiment, the travel of the silicone key is specified to be less than the limit travel of the lower end of the rotating shaft mating part on the button 1. The purpose is to ensure that the various components can work in coordination when the button 1 is in normal use, to avoid damage to the internal structure due to excessive pressing of the button, and to ensure the stability and reliability of the switch button function.

[0040] For example, after assembly, the travel of each silicone key in the multiple sets of silicone keys can be 1.5mm along the downward pressing direction of key 1, and the corresponding limiting travel of the lower end of the rotating shaft mating part to key 1 can be 1.6mm. In this example, the travel of the silicone keys in the downward pressing direction of key 1 is 1.5mm. From the perspective of elastic deformation, the silicone key is an elastic component. When it is pressed by an external force, it will undergo elastic deformation. This 1.5mm refers to the deformation along the direction of force under normal operating conditions, from the initial state when the silicone key is not pressed to when it is compressed to its limit position due to external force. For example, when key 1 is pressed with a finger, this force is transmitted to the silicone key through key 1, and the silicone key will begin to compress and deform until its deformation reaches a length of 1.5mm. This is the maximum elastic deformation it can achieve under normal operating conditions. From the perspective of functional triggering, within this 1.5mm travel range, the silicone key can effectively contact the corresponding contacts and other structures on the printed circuit board assembly 4, thereby triggering the corresponding circuit conduction or other functions. In other words, as the silicone key is pressed, it gradually compresses and deforms. When it reaches a certain degree (i.e., the deformation is within a 1.5mm travel range), it can ensure accurate matching with the relevant circuit structure, enabling the switch button to perform pre-set functions such as signal transmission and function activation. Simultaneously, the design of multiple silicone keys on the silicone pad 3 means that only one key needs to be triggered to achieve the function, improving the fault tolerance and stability of function triggering, reducing the risk of functional failure due to the malfunction of individual silicone keys, and ensuring stable operation of the switch button under various environmental and usage conditions, maintaining the normal operation of the equipment. Corresponding to the 1.5mm travel range of the silicone key, the lower end of the rotating shaft mating part can limit the travel range of the button 1 to 1.6mm. This limiting travel range is slightly larger than the travel range of the silicone key, and its purpose is to protect the silicone key and the printed circuit board assembly 4. Figure 5 and Figure 12 As shown, when button 1 is pressed down, after the silicone key completes a 1.5mm travel and triggers the circuit, button 1 still has some leeway. However, when button 1 continues to be pressed down to 1.6mm and reaches the limit travel, the lower end of the structure of the rotating shaft mating part that accommodates the rotating shaft will limit button 1, preventing it from being pressed down excessively. At this time, the force on button 1 will not be entirely transmitted to the printed circuit board assembly 4, but will be partially borne by the structure of the upper shell 2. In this way, even if the user applies a large pressing force during use, it can prevent irreversible damage to the silicone key caused by excessive pressing of button 1, and at the same time prevent button 1 from directly squeezing the printed circuit board assembly 4, thereby protecting the stability of the entire switch button structure and circuit, and ensuring the reliability and service life of the product.

[0041] In an optional embodiment, after assembly, button 1 and silicone pad 3 have a preset pre-pressure amount in the vertical direction.

[0042] In this embodiment, after assembly, button 1 and silicone pad 3 have a preset pre-pressure in the vertical direction, such as 0.2mm. When the device is placed normally or subjected to slight vibration, the pressure generated by the pre-pressure can firmly fix button 1 in its initial position, preventing it from shaking or shifting. Without pre-pressure, button 1 may shift due to vibration, affecting not only the user's operating feel but also potentially causing accidental triggering. Pre-pressure ensures that button 1 always remains in a stable initial position when not subjected to external force.

[0043] Meanwhile, the pre-pressure design significantly improves the user's tactile feedback. Specifically, when the user presses button 1, the pre-pressure provides initial resistance, offering clear feedback and allowing the user to clearly perceive that the button has been pressed. Simultaneously, as the button is pressed further, the elasticity of the silicone pad 3 gradually comes into play, further enhancing the tactile feel and making the operation more layered and comfortable. For example, in button operation on electronic devices, this improved feel helps users more accurately control the pressure applied and judge the result, thus enhancing the user experience.

[0044] In the optional embodiment technical solutions, such as Figure 7 and Figure 8 As shown, button 1 may include button cap 101. A first pivot 103 is integrally provided at the bottom center of the third side of button cap 101, and a second pivot is integrally provided at the bottom center of the fourth side opposite to the third side (the second pivot is not shown due to the angle of the schematic diagram). The pivot mating part may include a first pivot mounting hole 201 and a second pivot mounting hole 202, wherein the first pivot mounting hole 201 is used to accommodate the first pivot 103, and the second pivot mounting hole 202 is used to accommodate the second pivot.

[0045] In this embodiment, button 1 is mainly composed of button cap 101. In the structural design of button cap 101, a first rotating shaft 103 and a second rotating shaft are integrally formed at the middle of the bottom of the third side and the middle of the bottom of the opposite fourth side, respectively. This symmetrical integral arrangement ensures the stability of the connection between the rotating shaft and button cap 101. The one-piece molding process makes the rotating shaft and button cap 101 a single unit, reducing weak points caused by splicing, and enabling it to withstand various stresses experienced by the button during frequent operation, preventing the rotating shaft from detaching from or loosening from the button cap. The symmetrical distribution of the two rotating shafts at the bottom provides a stable support point for the rotation of button 1, ensuring the balance of the button during rotation.

[0046] Meanwhile, the upper shell 2 has a pivot fitting part corresponding to the pivot of button 1, which includes a first pivot mounting hole 201 and a second pivot mounting hole 202. The first pivot mounting hole 201 can precisely accommodate the first pivot 103, and the second pivot mounting hole 202 is used to accommodate the second pivot. The size and shape of these mounting holes are adapted to the corresponding pivot height. In terms of size, a clearance fit is usually adopted. For example, if the diameter of the first pivot 103 is designed to be 3mm, the diameter of the first pivot mounting hole 201 may be set between 3.05-3.1mm, which can ensure that the first pivot 103 can rotate flexibly in the hole, and also ensure that the connection has a certain degree of stability to avoid excessive shaking.

[0047] During the assembly of the switch button, the first rotating shaft 103 of button 1 is aligned with the first rotating shaft mounting hole 201 of the upper shell 2, and the second rotating shaft is aligned with the second rotating shaft mounting hole 202. Then, button 1 is installed onto the upper shell 2. After assembly, button 1 can rotate around the first rotating shaft 103 and the second rotating shaft, constrained by the first rotating shaft mounting hole 201 and the second rotating shaft mounting hole 202. When the user applies external force to button 1, such as pushing button cap 101 back and forth, button 1 will rotate around these two rotating shafts, thereby driving the silicone key extrusion plate at the bottom of the button to extrude the silicone key on the silicone pad 3, realizing multiple triggering functions of the switch button.

[0048] In an optional embodiment, the lower shell 5 and the upper shell 2 can be assembled using a snap-fit ​​structure.

[0049] In this embodiment, matching snap-fit ​​components are provided at the edges of the upper shell 2 and the lower shell 5. Along the contour of the upper shell 2, protruding snaps are distributed; these snaps can be hook-shaped, wedge-shaped, etc., and possess a certain degree of elasticity, allowing them to deform under stress. Correspondingly, the lower shell 5 has grooves on its edge that precisely match the shape and position of the snaps on the upper shell 2. The size and shape of these grooves match the snaps to ensure smooth engagement. For example, the width tolerance between the snaps and the grooves needs to be controlled within a small range to ensure a tight fit.

[0050] During assembly, align the upper shell 2 and lower shell 5 in the correct orientation, ensuring the latches of the upper shell 2 are aligned with the slots of the lower shell 5. Then, gradually move the upper shell 2 closer to the lower shell 5. When the latches contact the edge of the slots, they will elastically deform due to increased pressure. This deformation allows the latches to slide smoothly into the slots. Once fully inserted, the latches return to their initial shape and lock securely in place, thus firmly connecting the upper shell 2 and lower shell 5 together. This process is simple, requires no additional tools, and effectively improves production efficiency while reducing assembly costs.

[0051] The snap-fit ​​structure provides a stable overall frame for the switch button 1. During daily use, whether it's the force generated by rotating or pressing the button, or external vibrations or impacts, the overall structure formed by the snap-fit ​​connection between the upper and lower shells effectively disperses these forces, preventing components from loosening or being damaged due to excessive localized stress. Furthermore, the snap-fit ​​structure also offers a degree of detachability. If it's necessary to repair or replace internal components of the switch button, such as the silicone pad 3 or the printed circuit board assembly 4, the upper and lower shells can be easily separated by applying appropriate external force to disengage the snap-fit ​​from the slot, facilitating subsequent maintenance.

[0052] In the optional embodiment technical solutions, such as Figure 10 As shown, several first screw posts 301 can be provided on both sides of the upper end of the silicone pad 3, correspondingly, as... Figure 11 As shown, a screw hole 401 is provided on the printed circuit board assembly 4 at a position corresponding to the first screw post 301, and a second screw post 501 is provided inside the lower housing 5 at a position corresponding to the screw hole 401 on the printed circuit board assembly 4 (e.g., ...). Figure 3 As shown in the figure, the first screw post 301, the screw hole 401 and the second screw post 501 in the corresponding positions are tightened by the screw 6.

[0053] In this example, the silicone pad 3, printed circuit board assembly 4, and lower shell 5 are securely assembled by connecting them with screws 6. During the assembly of the switch button, the screws 6 are passed sequentially through the first screw post 301 of the silicone pad 3, the screw hole 401 of the printed circuit board assembly 4, and finally screwed into the second screw post 501 of the lower shell 5. By tightening the screws 6, the silicone pad 3, printed circuit board assembly 4, and lower shell 5 are tightly fixed together. This connection method provides stable physical support for the entire switch button structure. On the one hand, it ensures that the position of the printed circuit board assembly 4 is fixed, preventing displacement due to vibration, external force, or other factors during use, thereby ensuring the stability of the circuit connection and preventing problems such as poor circuit contact caused by displacement of the printed circuit board assembly 4, which would affect the normal function of the switch button. On the other hand, it also ensures that the silicone pad 3 can be stably positioned in the corresponding position, ensuring the precise fit between the silicone pad and the button 1, and ensuring that the silicone pad can be properly triggered during button operation, realizing the multiple triggering functions of the switch button.

[0054] In the optional embodiment technical solutions, such as Figure 7 As shown, button 1 can be made of engineering plastic, and a rib 102 is integrally provided on the top of button 1.

[0055] Engineering plastics possess high mechanical strength, enabling them to withstand the pressure and friction from frequent operation, preventing damage such as cracking and deformation of the buttons during long-term use and effectively extending their lifespan. For example, even under repeated pressing and pushing operations, the engineering plastic button 1 maintains a stable structure. Engineering plastics also have excellent insulation properties, preventing short circuits and other circuit failures caused by the conductivity of button 1, ensuring the electrical safety of the equipment. Furthermore, engineering plastics have excellent molding and processing properties, allowing for the fabrication of complex and high-precision buttons through processes such as injection molding, meeting the structural requirements for precise fit between button 1 and other components, such as the upper shell 2 and the silicone pad 3.

[0056] Meanwhile, the integrated rib 102 on the top of button 1 enhances the user experience. Specifically, when the user presses the button, the rib 102 provides a comfortable and stable point of force for the fingers. For example, when pushing button 1 to perform the forward and backward push function, the fingers can exert force more effectively, reducing operational errors caused by uneven force application, making the operation smoother and more precise. The rib 102 also increases the surface area and friction of the top of button 1, further preventing fingers from slipping during operation, ensuring that each user operation is accurately transmitted to button 1, and improving the reliability of button 1 operation.

[0057] In the optional embodiment technical solutions, such as Figure 7 As shown, a first protrusion 105 is integrally provided at the middle position of the first silicone key extrusion plate 104 side end, and a second protrusion is integrally provided at the middle position of the second silicone key extrusion plate side end; as Figure 8 As shown, the upper shell 2 has a first protrusion limiting groove 203 near the first protrusion 105, and a second protrusion limiting groove 204 near the second protrusion. The first protrusion limiting groove 203 abuts against the first protrusion 105 when the button 1 rotates to a predetermined angle in the first direction, thereby limiting the rotation amplitude of the button 1 in the first direction. The second protrusion limiting groove 204 abuts against the second protrusion when the button 1 rotates to a predetermined angle in the second direction (e.g.,...). Figure 6 As shown), this limits the rotation range of button 1 in the second direction.

[0058] In this embodiment, a first protrusion 105 is integrally formed at the middle position of the side end of the first silicone key extrusion plate 104, and a second protrusion at the corresponding position of the second silicone key extrusion plate are integrally formed with the extrusion plate. During the rotation of the key 1, the protrusion moves synchronously with the extrusion plate. Taking the first protrusion 105 as an example, when the key 1 rotates in the first direction, the movement trajectory of the first protrusion 105 reflects the rotation process of the key. Its contact with the upper shell 2 determines whether the rotation is restricted, thereby effectively preventing component collision, damage or functional abnormality caused by excessive rotation, and ensuring that the key operates at a safe angle.

[0059] like Figure 9 As shown, the first protrusion limiting groove 203 on the upper shell 2 is located near the first protrusion 105, and the second protrusion limiting groove 204 is located near the second protrusion, thereby ensuring accurate contact with the limiting position when the button 1 is rotated to a predetermined angle. In this design, the shape and size of the limiting groove must be strictly matched with the protrusion; the width can be slightly larger than the diameter of the protrusion, and the depth is moderate, thus ensuring that the protrusion can smoothly enter and achieve the limiting position while avoiding excessive looseness or tightness that would affect the smoothness of rotation. Figure 6 As shown, when button 1 is pushed along the X direction to trigger a specific function, button 1 will rotate around the two pivots. Within the normal operating range, the rotation of button 1 can accurately cause the silicone key extrusion plate at the bottom to press the corresponding silicone key, thus triggering the function. However, if the user applies too much force, causing the rotation angle of button 1 to exceed the predetermined angle, the protrusion on the left will abut against the bottom of the corresponding limiting groove. At this time, due to the blocking effect of the bottom of the limiting groove, the button 1 can be effectively prevented from rotating further, limiting the rotation range of button 1 to a safe range. Thus, this structural design can ensure that button 1 will not damage the printed circuit board assembly 4 when subjected to a large pushing force.

[0060] In real-world scenarios, when button 1 is subjected to a large pushing force, without a limiting structure, button 1 may rotate excessively. Excessive rotation could cause the structure at the bottom of button 1 to collide with the printed circuit board assembly 4, or cause the silicone pad 3 and other components to shift, indirectly damaging the printed circuit board assembly 4. For example, excessive rotation could cause excessive compression or misalignment between the silicone button and the circuit contacts on the printed circuit board assembly 4, affecting the stability of the circuit connection and potentially damaging circuit components. The limiting groove and the protrusion abut against each other, promptly limiting the rotation of button 1 when it approaches an angle that could cause damage, preventing unnecessary contact and collision between button 1 and the printed circuit board assembly 4. This protects the integrity and normal function of the printed circuit board assembly 4, ensuring the stable operation of the entire switch button system.

[0061] In this application's technical solution, the rotational movement of the button 1 includes rotation in both clockwise and counterclockwise directions. When the button 1 rotates clockwise, its first side silicone key pressing plate presses the silicone key on the corresponding side of the central region of the silicone pad 3, triggering the circuit contact corresponding to that silicone key to conduct, thus achieving a first function. When the button 1 rotates counterclockwise, its second side silicone key pressing plate presses the silicone key on the other corresponding side of the central region of the silicone pad 3, triggering the circuit contact corresponding to that other corresponding silicone key to conduct, thus achieving a second function. When the button 1 is pressed downwards, multiple sets of protruding silicone keys are simultaneously pressed, triggering the circuit contact corresponding to all silicone keys to conduct, thus achieving a third function.

[0062] In this design, when button 1 is rotated clockwise, the silicone key pressing plate on its bottom first side will move accordingly. Taking a real product as an example, such as on some multi-functional remote controls, this clockwise rotation might be set to switch to the next channel. During operation, the user gently pushes button 1 with their finger to rotate it clockwise, causing button 1 to rotate around the pivots on both sides. Since the silicone key pressing plate on the bottom first side of button 1 is an integral structure with button 1, the pressing plate rotates along with button 1. At this time, the pressing plate presses down on the silicone key on the corresponding side of the middle area of ​​the silicone pad 3. Taking the example of four silicone keys symmetrically distributed in two groups at the upper end of the silicone pad 3, assuming the first silicone key 302 and the second silicone key 303 are located on the corresponding side, these two silicone keys will be compressed. The silicone keys themselves are elastic and will deform elastically after being compressed, thus contacting and conducting with the corresponding circuit contacts on the printed circuit board assembly 4. After the circuit is connected, the corresponding electrical signal is transmitted, thereby realizing the first function, such as channel switching. This design allows users to easily perform specific functions through a simple clockwise rotation, making the operation intuitive and efficient.

[0063] Similar to clockwise rotation, when button 1 is rotated counterclockwise, the silicone key pressing plate on the second side activates. Again, using a remote control as an example, counterclockwise rotation might be used to switch to the previous channel. When the user pushes button 1 counterclockwise, button 1 rotates counterclockwise around its axis, causing the silicone key pressing plate on the second side to rotate. The pressing plate then presses the silicone keys on the other side of the central area of ​​the silicone pad 3, such as the third silicone key 304 and the fourth silicone key 305. After being deformed by the pressure, the silicone keys connect with the corresponding circuit contacts on the printed circuit board assembly 4, generating different electrical signals and thus achieving the second function.

[0064] The situation changes when button 1 is pressed downwards. At this time, the structure at the bottom of button 1 simultaneously compresses multiple sets of protruding silicone keys. For example, in confirmation operation scenarios of some electronic devices, the user needs to press button 1 to confirm the selected option or execute a command. During the pressing process, button 1 moves downwards as a whole, and its bottom applies pressure evenly to all the silicone keys on the silicone pad 3. All the silicone keys simultaneously undergo elastic deformation, connecting with their corresponding circuit contacts on the printed circuit board assembly 4. This comprehensive circuit connection triggers a specific combination of electrical signals, thereby achieving a third function, such as a confirmation operation.

[0065] In summary, the multi-trigger switch button in this application, through its structural design, enables different functions to be triggered by three different operating methods: clockwise rotation, counterclockwise rotation, and downward pressing. This design not only enriches the functionality of a single button but also optimizes the user experience, achieving more functions within a limited space.

[0066] The working principle of this utility model is illustrated below with a complete embodiment: Button 1 forms a rotating pair with the corresponding first rotating shaft mounting holes 201 and second rotating shaft mounting holes 202 on the upper shell 2 via rotating shafts (first rotating shaft 103 and second rotating shaft) on both sides. When the user applies a horizontal external force to button 1, according to the rotational law of rigid bodies, the external force will generate a torque relative to the rotating shaft, causing button 1 to rotate around the rotating shaft. For example, during operation, if the user pushes button 1 forward, button 1 will rotate clockwise around the rotating shaft; if pushed backward, it will rotate counterclockwise. During rotation, the first silicone key pressing plate 104 or the second silicone key pressing plate at the bottom of button 1 will press the two silicone keys at the corresponding positions on the silicone pad 3 as button 1 rotates.

[0067] The upper end of the silicone pad 3 is provided with a first silicone key 302, a second silicone key 303, a third silicone key 304, and a fourth silicone key 305, which are arranged in two groups on both sides. When the button 1 is rotated, the extrusion plate at its bottom will extrude the corresponding silicone key. Taking the first silicone key extrusion plate 104 as an example, when the button 1 is rotated in a certain direction and the first silicone key extrusion plate 104 contacts the first silicone key 302 and the second silicone key 303, it will apply pressure to them, causing the silicone keys to elastically deform, thereby triggering the corresponding function. Since the silicone keys are elastic, they will return to their original shape when the external force is removed. In the vertical direction, the button 1 can move relative to the upper shell 2. When a vertically downward force is applied, the button 1 is pressed down as a whole. At this time, the structure at the bottom of the button 1 will press the four silicone keys simultaneously, making the circuit conductive and realizing the switching function.

[0068] The upper shell 2 has a button mounting hole 205, in which the button 1 is embedded, allowing relative movement in the vertical direction. This design ensures the button 1 has room to move while limiting its movement within a certain range. The lower shell 5 and the upper shell 2 are assembled using a snap-fit ​​structure. This snap-fit ​​structure ensures easy assembly while providing a stable connection, forming a stable overall frame that can withstand the force generated by button operation and external vibrations and impacts. Several first screw posts 301 are provided on both sides of the upper end of the silicone pad 3. The printed circuit board assembly 4 has corresponding screw holes 401, and the lower shell 5 has second screw posts 501. By tightening with screws 6, the position of the silicone pad 3 and the printed circuit board assembly 4 is further fixed, ensuring that there is no displacement during use and guaranteeing the stability of the circuit connection and the accuracy of the fit between the silicone pad and the button 1. After assembly, button 1 and silicone pad 3 have a 0.2mm pre-pressure in the vertical direction. This pre-pressure not only keeps button 1 stable when it is not subjected to external force, preventing shaking and displacement, but also provides a certain resistance and elastic feedback for the operation of button 1, enhancing the operating feel. At the same time, it ensures close contact between the silicone pad and button 1, ensuring reliable triggering of the function.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
