Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures and electrical switch control equipment, and in particular to a silent switch device. Background Technology

[0002] In recent years, with the continuous improvement of living standards, people's demands for the quality of their daily living or working environments have also been increasing, especially the demand for a quiet environment at home or in the office, hoping to avoid being disturbed when resting, sleeping, or focusing on work. As a common lighting and electrical control device in home or office environments, the quietness of switch devices during operation is increasingly attracting users' attention.

[0003] In everyday life, common switching devices such as multi-control switches or double-way reversing switches typically use a rocker arm as the trigger mechanism. This rocker arm's trigger terminal contacts or disconnects from a fixed terminal at a corresponding position. Correspondingly, current industry practices for reducing noise during switch operation typically involve incorporating a mechanism within the switch to provide resistance to the rocker arm's rotation. This mitigates the structural impact when the rocker arm contacts the fixed terminal during operation, thereby reducing noise generated during silent switch operation.

[0004] However, although the existing noise reduction methods mentioned above can meet the basic noise reduction requirements of the switching device, their obstructing effect on the action of the triggering mechanism such as the silver point rocker will directly affect the matching effect when the terminals on the silver point rocker contact the corresponding fixed terminals, reduce the contact force between the terminals, and cause insufficient or even poor contact between the terminals on the silver point rocker and the corresponding fixed terminals. This results in the overall switching operation of the corresponding switching device being inadequate, affecting the control accuracy and working reliability of the switching device.

[0005] In view of this, how to optimize the component structure of the silent switch device, so as to reduce the noise generated by the cooperation of the components during its switching operation and ensure sufficient contact between its terminals, is an important technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to provide a silent switch device that produces less noise when its components work together during the switching operation, and whose terminals can make full contact and reliably connect.

[0007] To solve the above-mentioned technical problems, this utility model provides a silent switch device, including a fixed frame, a button located at the front of the fixed frame, an electrical box located at the rear of the fixed frame, and a pressure plate installed between the fixed frame and the electrical box. The electrical box is provided with two terminal groups, each of which includes at least one terminal. The two terminal groups are symmetrically arranged along the extension direction of the bottom inner wall of the electrical box and are clearance-fitted to form a trigger groove between the two terminal groups.

[0008] A silver dot rocker is provided in the trigger slot. The bottom edge of the silver dot rocker abuts against the bottom inner wall of the electrical box to form a reference side axis. The top of the silver dot rocker is linked to the button through a buffer transmission assembly so that the silver dot rocker can swing back and forth around the reference side axis. The top of the silver dot rocker is also provided with a trigger terminal that can contact and cooperate with the wiring terminal.

[0009] A transmission slot runs through the middle of the pressure plate. The buffer transmission assembly includes a transmission frame inserted into the transmission slot and a damping frame inserted into the transmission frame. A drive spring is also inserted into the middle of the transmission frame. The top end of the drive spring is fixedly connected to the transmission frame, and the bottom end of the drive spring is linked to the top end of the silver dot rocker. A damping spring is inserted into the middle of the damping frame. The top end of the damping spring is fixed to the damping frame, and the bottom end of the damping spring is linked to the top end of the silver dot rocker.

[0010] The top end of the transmission frame is hinged to the pressure plate, the top end of the damping frame is hinged to the transmission frame, and the axes of the hinge shafts of the transmission frame, the damping frame, and the reference side shaft are parallel to each other.

[0011] Preferably, the transmission slot is provided with a buffer beam extending axially along the reference side axis. There are two buffer beams, which are symmetrically arranged on both sides of the transmission frame along the axis perpendicular to the reference side axis. Buffer arms are provided on the top two sides of the transmission frame respectively along the axis perpendicular to the reference side axis. The free end of the buffer arm can be aligned and abutted against the buffer beam to make the buffer arm elastically deform.

[0012] Preferably, the free end of the buffer arm has a bent retainer that can fit against the outer circumferential surface of the buffer beam.

[0013] Preferably, there are at least four buffer arms, and each buffer arm array is arranged on the outer peripheral wall of the transmission frame.

[0014] Preferably, the lower part of the transmission frame has a transmission sleeve, the drive spring is inserted into the transmission sleeve, and the bottom end of the drive spring extends out of the bottom end of the transmission sleeve;

[0015] The lower part of the damping frame has a damping sleeve, the damping spring is inserted into the damping sleeve, and the bottom end of the damping spring extends out of the bottom end of the damping sleeve.

[0016] Preferably, the top end of the drive spring is linked to the top end of the transmission sleeve, and the top end of the damping spring is linked to the top end of the damping sleeve.

[0017] Preferably, the top of the silver dot rocker is provided with a transmission latch and a damping latch. The transmission latch engages and is linked with the bottom end of the drive spring, and the damping latch engages and is linked with the bottom end of the damping spring.

[0018] Preferably, the trigger terminal is located in the middle of the damping head.

[0019] Preferably, the inner cavity of the transmission frame is provided with an inner support plate extending along an axis perpendicular to the reference side axis in the middle. The two ends of the inner support plate are respectively fixedly connected to the inner wall of the transmission frame to divide the inner cavity of the transmission frame into a transmission cavity located on one side of the inner support plate and a damping cavity located on the other side of the inner support plate. The transmission sleeve is installed in the transmission cavity, and the damping frame is hingedly installed in the damping cavity.

[0020] Preferably, a cushioning pad that abuts against the button is provided on the front wall of the fixing frame.

[0021] Compared to the aforementioned background technology, the silent switch device provided by this utility model, during operation, is operated by the user pressing a button to drive the silver dot rocker to rotate around the reference side axis through the buffer transmission component. This causes the silver dot rocker to rotate from the position that matches one set of terminal blocks to the position that matches another set of terminal blocks, thereby driving the trigger terminal to act accordingly. This realizes the conduction triggering or separation between the trigger terminal and the terminal block that connects or disconnects the switch circuit, thus realizing the switching operation of the silent switch device. During this period, when the button is pressed down to rotate the transmission frame around its hinge axis to the target side, causing the silver dot rocker to swing around the reference edge axis to the terminal block on the target side, the top of the drive spring swings synchronously with the rotation of the transmission frame. This causes the middle of the drive spring to arch in the opposite direction of the swing direction of the top of the drive spring due to pressure. Simultaneously, the bottom of the drive spring drives the silver dot rocker to begin rotating around the reference edge axis. At this time, the damping spring is not yet under structural pressure and therefore remains in a naturally extended state. Afterwards, the transmission frame continues to be compressed and rotates until it drives the damping frame to rotate synchronously around its own hinge axis, causing the top of the damping spring to swing synchronously with the damping frame. This causes the middle of the damping spring to arch in the opposite direction of the swing direction of the drive spring due to pressure. The top of the rocker arches upwards in the opposite direction of its swing direction. The elastic deformation of the damping spring creates a gradually increasing elastic resistance to overcome the driving force provided by the drive spring. This slows down the swing rate of the rocker by linking the bottom of the damping spring with the top of the rocker. Then, the elastic deformation of the drive spring reaches its maximum amplitude and passes the dead point. At this time, the driving force applied by the drive spring to the rocker is greater than the resistance applied by the damping spring. This causes the rocker to swing to the target side, so that the trigger terminal at the top of the rocker can fully contact and reliably connect with the wiring terminal on the target side, completing the contact switching and realizing the switching operation of the switching circuit. At this time, both the damping spring and the drive spring return to their natural extended state. Therefore, by utilizing the elastic resistance generated by the deformation of the damping spring under compression, a moderate hindrance is created to the swing process of the silver-point rocker, effectively mitigating the structural impact during the swing process and preventing large impacts when the silver-point rocker contacts the terminal block. This significantly reduces the noise when the silver-point rocker contacts the terminal block, thereby significantly reducing the overall noise when the button and other moving parts of the silent switch device are activated, making the operation of the silent switch device quieter and smoother. At the same time, the driving force generated by the re-expansion of the drive spring after passing the dead point position overcomes the resistance generated by the deformation of the damping spring, driving the silver-point rocker to swing smoothly to the target position. This ensures that the trigger terminal can make full and reliable contact with the terminal block at the target position, achieving reliable conduction of the corresponding terminal circuit. This effectively avoids the occurrence of poor terminal contact and fully guarantees the operating accuracy of the silent switch device, ensuring smooth switching and reliable connection of the switching circuit.

[0022] In another preferred embodiment of this utility model, the transmission groove is provided with a buffer beam extending axially along the reference side axis. There are two buffer beams, symmetrically arranged on both sides of the transmission frame along an axis perpendicular to the reference side axis. Buffer arms protrude from the top two sides of the transmission frame along an axis perpendicular to the reference side axis. The free ends of the buffer arms can align and abut against the buffer beams, causing elastic deformation. When the transmission frame rotates towards the target side under pressure from the button, the buffer arm closer to the target side contacts the buffer beam closer to the target side. As the transmission frame continues to rotate, a contacting force is formed between the contacting buffer arm and the buffer beam. At this time, the buffer arm undergoes moderate elastic deformation under force to alleviate the structural impact during the rotation of the transmission frame, further reducing the rotation speed of the transmission frame and simultaneously slowing down the swing speed of the silver dot rocker. This further hinders the swing process of the silver dot rocker, further reducing the structural impact and noise when the trigger terminal on the silver dot rocker contacts the wiring terminal on the target side, making the operation of the silent switch device quieter and smoother. Once the silver dot rocker arm has swung into position, the transmission frame is relieved of stress. At this point, the buffer arm and the buffer beam are no longer in contact, and the buffer arm elastically resets and returns to its natural extended state. Attached Figure Description

[0040] In specific implementation methods, such as Figure 1 As shown, the silent switch device provided by this utility model includes a fixing frame 10, a button 101 located at the front of the fixing frame 10, an electrical box 11 located at the rear of the fixing frame 10, and a pressure plate 13 installed between the fixing frame 10 and the electrical box 11. The electrical box 11 is provided with two terminal groups 111, each terminal group 111 including at least one terminal 112. The two terminal groups 111 are symmetrically arranged along the extension direction of the bottom inner wall of the electrical box 11 and are clearance-fitted to form a trigger groove 113 between the two terminal groups 111. A silver dot rocker 12 is provided in the trigger slot 113. The bottom edge of the silver dot rocker 12 abuts against the bottom inner wall of the electrical box 11 to form a reference side axis 121. The top of the silver dot rocker 12 is linked to the button 101 through a buffer transmission assembly so that the silver dot rocker 12 can swing back and forth around the reference side axis 121. The top of the silver dot rocker 12 is also provided with a trigger terminal 122 that can contact and cooperate with the wiring terminal 112.

[0041] A transmission slot 131 runs through the middle of the pressure plate 13, combined with... Figure 2 As shown, the buffer transmission assembly includes a transmission frame 14 inserted into the transmission slot 131 and a damping frame 15 inserted into the transmission frame 14. A drive spring 141 is also inserted in the middle of the transmission frame 14. The top end of the drive spring 141 is fixedly connected to the transmission frame 14, and the bottom end of the drive spring 141 is linked to the top end of the silver dot rocker 12. A damping spring 151 is inserted in the middle of the damping frame 15. The top end of the damping spring 151 is fixed to the damping frame 15, and the bottom end of the damping spring 151 is linked to the top end of the silver dot rocker 12. The top end of the transmission frame 14 is hinged to the pressure plate 13, and the top end of the damping frame 15 is hinged to the transmission frame 14. The axes of the hinge pins of the transmission frame 14, the damping frame 15, and the reference side shaft 121 are parallel to each other.

[0042] For ease of understanding and as a reference, taking a silent switch device installed on a wall to control the on / off state of electrical appliances such as lights as an example, the electrical box 11 is embedded in the switch mounting hole in the wall; the pressure plate 13 is aligned and fastened into the mounting hole; the pressure plate 13 can be a frame structure or a regular or irregular plate structure; and the mounting bracket 10 is installed on the wall surface and aligned with the pressure plate 13; the mounting bracket 10 is usually a frame structure. The button 101 is correspondingly installed within the frame structure of the mounting bracket 10. If a... Figure 1 The rocker-type button 101 shown is hinged to the mounting bracket 10 at its center; if a push-button type button 101 is used, it can be installed inside the mounting bracket 10. Correspondingly, the main extension surface of the mounting bracket 10, the bottom inner wall of the electrical box 11, and the wall surface are parallel to each other. Unless otherwise specified, descriptions of the relative positions and arrangement directions of components in the rest of this document can be understood in accordance with the corresponding descriptions here, and will not be repeated here.

[0043] During specific equipment operation, the user presses button 101 to drive the silver dot rocker 12 to rotate around the reference side shaft 121 through the buffer transmission component. This causes the silver dot rocker 12 to rotate from the position that matches one set of terminal blocks 111 to the position that matches another set of terminal blocks 111. This causes the trigger terminal 122 to move accordingly, realizing the conduction triggering or separation between the trigger terminal 122 and the terminal block 112 that connects or disconnects the switch circuit, thereby realizing the switching operation of the silent switch device. During this period, when button 101 is pressed down to drive transmission frame 14 to rotate around its hinge axis towards the target side, thereby causing silver dot rocker 12 to swing around reference side axis 121 toward the terminal 112 on the target side, the top of drive spring 141 swings synchronously with the rotation of transmission frame 14. This causes the middle part of drive spring 141 to arch in the opposite direction of the swing direction of the top of drive spring 141 due to pressure. At the same time, the bottom of drive spring 141 drives silver dot rocker 12 to start rotating around reference side axis 121. At this time, damping spring 151 has not yet been subjected to structural pressure and therefore remains in a naturally extended state. Afterwards, transmission frame 14 continues to be compressed and continues to rotate until it drives damping frame 15 to rotate synchronously around its own hinge axis and causes the top of damping spring 151 to swing synchronously with damping frame 15. This causes the middle part of damping spring 151 to arch in the opposite direction of the swing direction of drive spring 141 due to pressure. The top of 141 arches upwards in the opposite direction of its swing direction. The elastic deformation of the damping spring 151 forms an increasing elastic resistance to overcome the driving force provided by the drive spring 141. This slows down the swing rate of the silver point rocker 12 through the linkage between the bottom of the damping spring 151 and the top of the silver point rocker 12. Then, the elastic deformation of the drive spring 141 reaches its maximum amplitude and passes the dead point position. At this time, the driving force applied by the drive spring 141 to the silver point rocker 12 is greater than the resistance applied by the damping spring 151 to the silver point rocker 12. This causes the silver point rocker 12 to swing to the target side so that the trigger terminal 122 at the top of the silver point rocker 12 can fully contact and reliably connect with the wiring terminal 112 on the target side, completing the contact switching and realizing the switching operation of the switching circuit. At this time, both the damping spring 151 and the drive spring 141 return to their natural extended state.

[0044] Therefore, by utilizing the elastic resistance generated by the compression deformation of the damping spring 151, a moderate hindrance is formed on the swing process of the silver dot rocker 12, effectively mitigating the structural impact during the swing process of the silver dot rocker 12 and avoiding large impacts when the silver dot rocker 12 contacts the terminal 112. This significantly reduces the noise when the silver dot rocker 12 contacts the terminal 112, thereby significantly reducing the overall noise when the button 101 and other moving parts of the silent switch device are activated, making the operation of the silent switch device quieter and smoother. At the same time, the driving force generated by the re-expansion of the drive spring 141 after passing the dead point position overcomes the resistance generated by the deformation of the damping spring 151, and drives the silver dot rocker 12 to swing smoothly to the target position, so that the trigger terminal 122 can make full and reliable contact with the terminal 112 at the target position, thereby achieving reliable conduction of the corresponding terminal circuit, effectively avoiding the occurrence of poor terminal contact, and fully ensuring the control accuracy of the silent switch device, ensuring smooth switching and reliable connection of the switch circuit.

[0045] It is easy to understand that, as shown in the figure, the silent switch device in this solution can be a multi-control switch device, a dual-way reversing switch device, or other switch devices that use a swing mechanism similar to the silver dot rocker 12 in this solution as the switch position triggering component. Depending on the specific type of the switch device, the wiring terminal 112 in this solution can be a fixed silver dot terminal, a saddle-shaped terminal, or other types of terminal structure components. In principle, anything that can adapt to the assembly structure of the components in this solution and meet the actual application needs of the silent switch device is acceptable.

[0046] Specifically, combined Figure 3As shown, the transmission slot 131 is provided with a buffer beam 132 extending axially along the reference side shaft 121. There are two buffer beams 132, which are symmetrically arranged on both sides of the transmission frame 14 in a direction perpendicular to the axis of the reference side shaft 121. Buffer arms 142 are provided on the top two sides of the transmission frame 14 respectively in a direction perpendicular to the axis of the reference side shaft 121. The free ends of the buffer arms 142 can be aligned and abutted against the buffer beams 132 so that the buffer arms 142 can undergo elastic deformation. When the transmission frame 14 rotates towards the target side under pressure from the button 101, the buffer arm 142 near the target side contacts the buffer beam 132 near the target side. As the transmission frame 14 continues to rotate, a contact force is formed between the contacting buffer arm 142 and the buffer beam 132. At this time, the buffer arm 142 undergoes moderate elastic deformation under force to alleviate the structural impact during the rotation of the transmission frame 14, further reducing the rotation speed of the transmission frame 14, and simultaneously slowing down the swing speed of the silver dot rocker 12. This further hinders the swing process of the silver dot rocker 12, further reducing the structural impact and noise when the trigger terminal 122 on the silver dot rocker 12 contacts the wiring terminal 112 on the target side, making the operation of the silent switch device quieter and smoother. After the silver dot rocker 12 swings to its position, the transmission frame 14 is relieved of stress. At this time, the contact between the buffer arm 142 and the buffer beam 132 is released, and the buffer arm 142 elastically resets and returns to its natural extended state.

[0047] More specifically, the free end of the buffer arm 142 has a bent retainer 143 that can fit against the outer peripheral surface of the buffer beam 132. As the part of the buffer arm 142 that directly contacts the buffer beam 132, the bent retainer 143 can effectively optimize the structural fit between the buffer arm 142 and the buffer beam 132 and the stress distribution during contact, so as to make the buffer arm 142 more stress-resistant and the overall component structure more reliable.

[0048] Generally, if the buffer beam 132 is a cylindrical structure, the outer wall of the bent bracket 143 that can contact and fit with the buffer beam 132 is a concave arc surface; if the buffer beam 132 is a polygonal prism, the outer wall of the bent bracket 143 that can contact and fit with the buffer beam 132 is a concave polygonal surface. In this way, it can be ensured that the bent bracket 143 and the buffer beam 132 are fully fitted to form a reliable surface contact, thereby optimizing the corresponding stress transmission effect.

[0049] Furthermore, in practical applications, there are at least four buffer arms 142, and each buffer arm 142 is arranged in an array on the outer peripheral wall of the transmission frame 14. Typically, the top structure of the transmission frame 14 has a roughly rectangular cross-section as shown in the figure. In this way, the buffer arms 142 can be arranged at the respective apex corners of the top structure of the transmission frame 14, so as to ensure that the two sides of the transmission frame 14 form a symmetrical assembly structure with double buffer arms 142. This makes the contact stress and support structure more balanced and stable when the transmission frame 14 rotates to either side, and avoids structural imbalance or misalignment of the transmission frame 14 and its related mating parts during operation.

[0050] On the other hand, the lower part of the transmission frame 14 has a transmission sleeve 144, in which the drive spring 141 is inserted, and the bottom end of the drive spring 141 extends out of the bottom end of the transmission sleeve 144. The transmission sleeve 144 can provide appropriate structural protection for the drive spring 141 and provide lateral and circumferential limits for the drive spring 141, so as to prevent the middle part of the drive spring 141 from arching excessively when the drive spring 141 undergoes elastic deformation under force, which would cause the drive spring 141 to loosen or misalign from the assembly position. This avoids structural failure or abnormal operation of the drive spring 141 and ensures the transmission adaptation effect between the drive spring 141 and the silver dot rocker 12 and other linkage components.

[0051] Correspondingly, the lower part of the damping frame 15 has a damping sleeve 152, and the damping spring 151 is inserted into the damping sleeve 152, with the bottom end of the damping spring 151 extending out of the bottom end of the damping sleeve 152. Similar to the function of the transmission sleeve 144 mentioned above, the damping sleeve 152 can provide appropriate structural protection for the damping spring 151 and provide lateral and circumferential limits for the damping spring 151, so as to prevent the middle part of the damping spring 151 from arching excessively when the damping spring 151 undergoes elastic deformation under force, which would cause the damping spring 151 to loosen or misalign from the assembly position. This avoids structural failure or abnormal operation of the damping spring 151 and ensures the transmission adaptation effect between the damping spring 151 and the silver dot rocker 12 and other linkage components.

[0052] Furthermore, the top end of the drive spring 141 is linked to the top end of the transmission sleeve 144, and the top end of the damping spring 151 is linked to the top end of the damping sleeve 152. Generally, the transmission sleeve 144 has a variable inner diameter structure that is narrower at the top and wider at the bottom. Specifically, the inner diameter of the upper inner diameter section of the transmission sleeve 144 is equal to or slightly smaller than the outer diameter of the drive spring 141, so that a suitable interference fit can be formed between the top end of the drive spring 141 and the upper section of the transmission sleeve 144, thereby reliably positioning the top end of the drive spring 141. Of course, auxiliary parts such as locking pins can also be used to reliably lock and fix the top end of the drive spring 141 to the top end of the transmission sleeve 144. In principle, any adaptable structure that can ensure the linkage connection between the top end of the drive spring 141 and the transmission sleeve 144 is acceptable.

[0053] Correspondingly, the damping sleeve 152 can also be a variable inner diameter structure, narrower at the top and wider at the bottom. The inner diameter of the upper inner diameter section of the damping sleeve 152 is equal to or slightly smaller than the outer diameter of the damping spring 151, so that a suitable interference fit can be formed between the top of the damping spring 151 and the upper section of the damping sleeve 152, thereby reliably positioning the top of the damping spring 151. Of course, auxiliary parts such as locking pins can also be used to reliably lock and fix the top of the damping spring 151 to the top of the damping sleeve 152. In principle, any adaptable structure that can ensure the linkage connection between the top of the damping spring 151 and the damping sleeve 152 is acceptable.

[0054] Furthermore, the top of the silver dot rocker 12 is provided with a transmission latch 123 and a damping latch 124. The transmission latch 123 engages and is linked with the bottom end of the drive spring 141, and the damping latch 124 engages and is linked with the bottom end of the damping spring 151. Generally, both the transmission latch 123 and the damping latch 124 have a laterally extending hook structure so as to be inserted laterally into the side gaps of the corresponding springs, achieving a more reliable engagement assembly and ensuring the linkage connection effect between the silver dot rocker 12 and the bottom ends of each spring.

[0055] Based on this, the trigger terminal 122 is located in the middle of the damping head 124, making the trigger terminal 122 closer to the linkage part of the damping spring 151, thereby further optimizing the damping effect of the damping spring 151 on the trigger terminal 122 when it moves with the silver dot rocker 12, making the contact between the trigger terminal 122 and the wiring terminal 112 at the corresponding target position more stable and gentle, so as to make the operation of the silent switch device quieter and smoother.

[0056] In addition, an inner support plate 145 extending along the axis perpendicular to the reference side shaft 121 is provided in the middle of the inner cavity of the transmission frame 14. The two ends of the inner support plate 145 are fixedly connected to the inner wall of the transmission frame 14, so as to divide the inner cavity of the transmission frame 14 into a transmission cavity 146 located on one side of the inner support plate 145 and a damping cavity 147 located on the other side of the inner support plate 145. The transmission sleeve 144 is installed in the transmission cavity 146, and the damping frame 15 is hingedly installed in the damping cavity 147. In this way, the transmission sleeve 144 and the damping frame 15 are placed in different cavities to ensure the independence and smoothness of their respective actions, making the working process of the transmission frame 14, the damping frame 15 and their respective adapter components more stable and efficient.

[0057] Combination Figure 4 As shown, in practical applications, a buffer pad 102 that abuts and matches the button 101 can also be provided on the front wall of the mounting bracket 10. This allows the button 101 to first contact the buffer pad 102 at the corresponding position when one end of the button 101 is pressed and approaches the mounting bracket 10. The elastic deformation of the buffer pad 102 after being pressed can alleviate the structural impact when the button 101 is pressed. At the same time, it can effectively avoid rigid contact between the button 101 and the mounting bracket 10 and the resulting noise, thereby further optimizing the silent effect of the silent switch device during actual operation and making its operation quieter and smoother.

[0058] Generally, the buffer pad 102 and the buffer arm 142 mentioned in this solution are preferably made of plastic. Of course, they can also be made of rubber or other materials with certain structural support capabilities and moderate elastic deformation capabilities. In principle, any material that can meet the actual operating conditions of the silent switch device is acceptable.

[0059] In summary, the silent switch device provided in this utility model, during its operation, is operated by the user pressing a button to drive the silver dot rocker to rotate around the reference side axis through the buffer transmission component. This causes the silver dot rocker to rotate from the position that matches one set of terminals to the position that matches another set of terminals, thereby driving the trigger terminal to act accordingly. This realizes the conduction triggering or separation between the trigger terminal and the terminal that connects or disconnects the switch circuit, thus realizing the switching operation of the silent switch device. During this period, when the button is pressed down to rotate the transmission frame around its hinge axis to the target side, causing the silver dot rocker to swing around the reference edge axis to the terminal block on the target side, the top of the drive spring swings synchronously with the rotation of the transmission frame. This causes the middle of the drive spring to arch in the opposite direction of the swing direction of the top of the drive spring due to pressure. Simultaneously, the bottom of the drive spring drives the silver dot rocker to begin rotating around the reference edge axis. At this time, the damping spring is not yet under structural pressure and therefore remains in a naturally extended state. Afterwards, the transmission frame continues to be compressed and rotates until it drives the damping frame to rotate synchronously around its own hinge axis, causing the top of the damping spring to swing synchronously with the damping frame. This causes the middle of the damping spring to arch in the opposite direction of the swing direction of the drive spring due to pressure. The top of the rocker arches upwards in the opposite direction of its swing direction. The elastic deformation of the damping spring creates a gradually increasing elastic resistance to overcome the driving force provided by the drive spring. This slows down the swing rate of the rocker by linking the bottom of the damping spring with the top of the rocker. Then, the elastic deformation of the drive spring reaches its maximum amplitude and passes the dead point. At this time, the driving force applied by the drive spring to the rocker is greater than the resistance applied by the damping spring. This causes the rocker to swing to the target side, so that the trigger terminal at the top of the rocker can fully contact and reliably connect with the wiring terminal on the target side, completing the contact switching and realizing the switching operation of the switching circuit. At this time, both the damping spring and the drive spring return to their natural extended state. Therefore, by utilizing the elastic resistance generated by the deformation of the damping spring under compression, a moderate hindrance is created to the swing process of the silver-point rocker, effectively mitigating the structural impact during the swing process and preventing large impacts when the silver-point rocker contacts the terminal block. This significantly reduces the noise when the silver-point rocker contacts the terminal block, thereby significantly reducing the overall noise when the button and other moving parts of the silent switch device are activated, making the operation of the silent switch device quieter and smoother. At the same time, the driving force generated by the re-expansion of the drive spring after passing the dead point position overcomes the resistance generated by the deformation of the damping spring, driving the silver-point rocker to swing smoothly to the target position. This ensures that the trigger terminal can make full and reliable contact with the terminal block at the target position, achieving reliable conduction of the corresponding terminal circuit. This effectively avoids the occurrence of poor terminal contact and fully guarantees the operating accuracy of the silent switch device, ensuring smooth switching and reliable connection of the switching circuit.
