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 damped silent switch. 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] Currently, common silent switches in daily life, such as multi-control switches or double-way reversing switches, typically reduce noise during operation by arranging elastic buffer structures, such as rubber pads, at the contact points between the operating button and the panel or pressure plate. This mitigates the structural impact during switch operation, thereby reducing the noise generated during operation.

[0004] However, due to the limitations of the elastic buffer components such as rubber pads used in the existing silent switches and the structure of the supporting components, the structural buffering and corresponding noise reduction effects achieved by the existing silent switch component structure are not ideal, resulting in poor overall silent performance of the silent switch, which in turn has an adverse effect on the quietness of the corresponding working environment.

[0005] In view of this, how to optimize the component structure of the switching device and reduce the noise generated by the cooperation of the components during the switching operation, so as to make its operation quieter, 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 damped silent switch, which produces less noise when the components work together during the switching operation, making the operation of the damped silent switch quieter.

[0007] To solve the above-mentioned technical problems, this utility model provides a damped silent switch, including a panel, a button located at the front of the panel, and an electrical box located at the rear of the panel. 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 gap-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 with the button 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] The electrical box has a damping groove on its side wall, and a damping shaft that can rotate about its own axis is inserted into the damping groove. The damping shaft and the damping groove are in frictional engagement along the circumference of the damping shaft. A linkage latch is linked to the outer wall of the damping shaft and extends into the trigger groove. The middle of the linkage latch is recessed and has a linkage slot for the top of the silver dot rocker to be inserted. The two outer walls of the silver dot rocker can abut against the two inner walls of the linkage slot, so that the silver dot rocker drives the damping shaft to swing about its own axis.

[0010] Preferably, a damping ring is detachably and coaxially sleeved on the outer periphery of the damping shaft. The damping ring is linked with the damping shaft in the circumferential direction, and the damping ring protrudes radially from the outer peripheral wall of the damping shaft. The outer wall of the damping ring is in contact with the inner wall of the damping groove and is rubbed and adapted in the circumferential direction.

[0011] Preferably, the damping ring is axially sleeved on the outer peripheral wall of the top and / or bottom of the damping shaft.

[0012] Preferably, a positioning blind hole is recessed on the bottom inner wall of the electrical box, the bottom end of the damping shaft is inserted into the positioning blind hole, and the damping shaft is rotatably engaged with the positioning blind hole.

[0013] Preferably, the bottom end of the damping shaft is linked to a positioning end head embedded in the positioning blind hole, the positioning end head is rotatably engaged with the positioning blind hole, and the positioning end head is detachably adapted to the damping shaft.

[0014] Preferably, the positioning blind hole is a spherical hole, and the positioning end is a spherical end that is concentrically arranged with the positioning blind hole and rotatably adapted.

[0015] Preferably, a positioning ring groove is recessed on the outer peripheral wall of the damping shaft, and the damping ring is coaxially embedded in the positioning ring groove.

[0016] Preferably, a linkage lug is connected between the outer wall of the damping shaft and the linkage platen, the width of the linkage lug increases from top to bottom, and the linkage platen is linked to the lower end outer wall of the linkage lug.

[0017] Preferably, the linkage slot is a U-shaped slot with its opening facing the silver dot rocker.

[0018] Preferably, the bottom inner wall of the electrical box is provided with an anti-slip pad layer that contacts and rolls with the reference side axis.

[0019] Compared to the aforementioned background technology, the damped silent switch provided by this utility model, during operation, is operated by the user pressing a button to rotate a silver dot rocker plate around a reference axis. This causes the silver dot rocker plate to rotate from its position matching one set of terminals to its position matching another set of terminals, thereby causing the trigger terminal to act accordingly. This enables the trigger terminal to conduct or separate from the terminals that connect or disconnect the switch circuit, thus realizing the switching operation of the damped silent switch. During this period, when the silver rocker swings around the reference axis in accordance with the button's action, it will first contact and abut against the inner wall of the linkage slot. Then, the silver rocker continues to move, driving the linkage plate to swing synchronously through the abutment transmission between it and the inner wall of the linkage slot. At this time, the damping shaft rotates synchronously on the fixed axis with the linkage plate. Due to the friction fit structure between the damping shaft and the damping groove, the damping shaft will be subject to frictional resistance from the outer wall and the inner wall of the damping groove during its fixed axis rotation, thus slowing down the rotation speed of the damping shaft. In this way, the abutment linkage between the linkage slot and the silver rocker transmits the resistance to the silver rocker, thereby slowing down the swing speed of the silver rocker and allowing it to continue swinging more smoothly until the silver rocker contacts the target terminal on the other side. Therefore, by utilizing the frictional resistance between the damping shaft and the damping groove, the structural impact during the swing of the silver point rocker is effectively mitigated, and a large impact is avoided when the silver point rocker comes into contact with the terminal block. This significantly reduces the noise when the silver point rocker comes into contact with the terminal block, thereby significantly reducing the overall noise when the button and other moving parts of the damped silent switch are triggered, making the operation of the damped silent switch quieter and smoother.

[0020] In another preferred embodiment of this utility model, a damping ring is coaxially sleeved on the outer periphery of the damping shaft. The damping ring is linked to the damping shaft circumferentially, and the damping ring protrudes radially from the outer peripheral wall of the damping shaft. The outer wall of the damping ring is in contact with the inner wall of the damping groove and is rubbed and adapted circumferentially. By linking the damping ring onto the damping shaft and using the damping ring as a direct contact component for rubbing and adapting with the damping groove, wear of the damping shaft caused by direct contact and rubbing and adapting between the main body structure of the damping shaft and the damping groove can be effectively avoided. This effectively ensures the reliability of the main body structure of the damping shaft, improves its operating condition tolerance, and makes the main body structure of the damping shaft more durable.

[0032] The core of this utility model is to provide a damped silent switch, which produces less noise when the components cooperate during the switching operation, making the operation of the damped silent switch quieter.

[0033] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] It should be noted in advance that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing" in this utility model should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Furthermore, in this invention, unless otherwise explicitly specified and limited, the first feature being "on" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0036] In addition, the terms "above," "over," and "on top" for the first feature and the second feature include the first feature being directly above or diagonally above the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "under," and "beneath" for the first feature and the second feature include the first feature being directly below or diagonally below the second feature, or simply indicating that the first feature is at a lower horizontal level than the second feature. The terms "above," "below," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] In specific implementation methods, in conjunction with references Figures 1 to 5 As shown, the damped silent switch provided by this utility model includes a panel 10, a button 101 located at the front of the panel 10, and an electrical box 11 located at the rear of the panel 10. The electrical box 11 is provided with two terminal groups 111. Each terminal group 111 includes 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 gap-fitted to form a trigger groove 113 between the two terminal groups 111.

[0038] 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 with the button 101 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.

[0039] The electrical box 11 has a damping groove 114 on its side wall. A damping shaft 13 that can rotate about its own axis is inserted into the damping groove 114. The damping shaft 13 and the damping groove 114 are in frictional engagement along the circumference of the damping shaft 13. A linkage plate 131 that extends into the trigger groove 113 is linkedly provided on the outer wall of the damping shaft 13. A linkage slot 132 for the top of the silver dot rocker 12 to be inserted is recessed in the middle of the linkage plate 131. The outer walls of the silver dot rocker 12 on both sides can abut against the inner walls of the linkage slot 132 on both sides, so that the silver dot rocker 12 drives the damping shaft to swing about its own axis.

[0040] For ease of understanding, and as a reference, taking a damped silent switch mounted on a wall for controlling the on / off of electrical appliances such as lights as an example, a conventional component arrangement in the industry involves the electrical box 11 being embedded in the switch mounting hole in the wall, while the panel 10 is mounted on the wall surface and aligned with the opening of the switch mounting hole. The panel 10 is typically a frame structure, and the button 101 is correspondingly mounted within this frame structure to connect with the rocker arm 12 and other actuating components inside the electrical box 11. Accordingly, the main extension surface of the panel 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 by referring to this description and will not be repeated here.

[0041] During specific equipment operation, the user presses button 101 to drive the silver dot rocker 12 to rotate around the reference side axis 121, thereby causing 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 act 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 damped silent switch. During this period, when the silver dot rocker 12 swings around the reference side axis 121 along with the action of the button 101, it will first contact and abut against the inner wall of the linkage slot 132. Then, the silver dot rocker 12 continues to move, so as to drive the linkage plate 131 to swing synchronously through the abutting transmission between it and the inner wall of the linkage slot 132. At this time, the damping shaft 13 rotates synchronously with the linkage plate 131. Due to the friction fit structure between the damping shaft 13 and the damping groove 114, the damping shaft 13 will be subject to frictional resistance from the outer wall of its outer wall and the inner wall of the damping groove 114 during the fixed-axis rotation, thus slowing down the rotation speed of the damping shaft 13. Thus, by utilizing the abutting linkage fit between the linkage slot 132 and the silver dot rocker 12, the resistance is transmitted to the silver dot rocker 12, thereby slowing down the swing speed of the silver dot rocker 12, so that it can continue to swing more smoothly until the silver dot rocker 12 contacts the target terminal 112 on the other side. Therefore, by utilizing the frictional resistance between the damping shaft 13 and the damping groove 114, the structural impact during the swing of the silver dot rocker 12 is effectively mitigated, and a large impact is avoided when the silver dot rocker 12 contacts the terminal block 112. This significantly reduces the noise when the silver dot rocker 12 contacts the terminal block 112, thereby significantly reducing the overall noise when the action components such as the button 101 of the damped silent switch are triggered, making the operation of the damped silent switch quieter and smoother.

[0042] It is easy to understand that, as shown in the figure, the damped silent switch in this solution can be a multi-control damped silent switch, a dual-channel reversing damped silent switch, or any other damped silent switch that uses a swing mechanism similar to the silver dot rocker 12 in this solution as the switch trigger component. Depending on the specific type of damped silent switch it can be adapted to, 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, any component that can adapt to the assembly structure of the damping shaft 13 and the linkage plate 131 in this solution, and meets the actual application requirements of the damped silent switch, is acceptable.

[0043] Accordingly, the linkage connection between button 101 and the silver dot rocker 12 can be achieved through a drive spring 102 connecting button 101 and silver dot rocker 12, as shown in the figure, in conjunction with a linkage connector 123 protruding from the top of silver dot rocker 12. Alternatively, it can be achieved through other transmission components. This solution does not involve a radical modification of the linkage connection structure between button 101 and silver dot rocker 12; therefore, the technical details here can be directly referred to conventional arrangements in the field. In principle, any arrangement that can meet the practical application needs of the damped silent switch is acceptable.

[0044] Specifically, a damping ring 133 is coaxially sleeved on the outer periphery of the damping shaft 13. The damping ring 133 is linked to the damping shaft 13 circumferentially, and the damping ring 133 protrudes radially from the outer peripheral wall of the damping shaft 13. The outer wall of the damping ring 133 is in contact with the inner wall of the damping groove 114 and is rubbed together circumferentially. By linking the damping ring 133 onto the damping shaft 13 and using the damping ring 133 as a direct contact component for rubbing together with the damping groove 114, wear of the damping shaft 13 caused by direct contact and rubbing between the main body structure of the damping shaft 13 and the damping groove 114 can be effectively avoided. This effectively ensures the reliability of the main body structure of the damping shaft 13, improves its operating condition tolerance, and makes the main body structure of the damping shaft 13 more durable.

[0045] If necessary, the damping ring 133 currently assembled on the damping shaft 13 can be removed to replace it with a damping ring 133 of different outer diameter and / or different outer wall friction coefficient. Replacing it with a damping ring 133 of larger outer diameter and / or larger outer wall friction coefficient increases the radial pressure of the fit between the damping ring 133 and the damping groove 114, thereby increasing the frictional resistance between the damping ring 133 and the damping groove 114 during rotation, further enhancing the buffering effect on the swing of the silver point rocker 12. Conversely, replacing it with a damping ring 133 of smaller outer diameter and / or smaller outer wall friction coefficient reduces the radial pressure of the fit between the damping ring 133 and the damping groove 114, thereby reducing the frictional resistance between the damping ring 133 and the damping groove 114 during rotation, appropriately reducing the resistance on the swing of the silver point rocker 12 and preventing damage to the silver point rocker 12.

[0046] Generally, the damping ring 133 is made of plastic material, but it can also be made of rubber or other engineering materials according to the actual working conditions. In principle, it should be easy to process and low in cost, so as to reduce the processing difficulty and overall application cost of the component with damping silent switch.

[0047] Specifically, the damping ring 133 is axially sleeved on the outer peripheral wall of the top and / or bottom of the damping shaft 13. Positioning the damping ring 133 near the top and bottom ends of the damping shaft 13 saves assembly space in the middle of the damping shaft 13, providing more ample assembly space for the linkage table 131. Furthermore, as a friction component that directly contacts the damping groove 114, arranging the damping ring 133 closer to the ends of the top and bottom of the damping shaft 13 further optimizes the stress distribution at the mating point between the damping shaft 13 and the damping ring 133 during rotation. This results in a more uniform force distribution on the main structure of the damping shaft 13 during rotation, leading to a smoother and more stable rotation process.

[0048] Based on this, a positioning blind hole 115 is recessed on the bottom inner wall of the electrical box 11. The bottom end of the damping shaft 13 is inserted into the positioning blind hole 115, and the damping shaft 13 is rotatably engaged with the positioning blind hole 115. Through the insertion engagement between the bottom end of the damping shaft 13 and the positioning blind hole 115, the positioning blind hole 115 can form a circumferential limit on the damping shaft 13, so as to prevent the damping shaft 13 from becoming loose or misaligned at the current position during rotation, thereby ensuring the rotation tracking and action stability of the damping shaft 13, so as to make the switching operation of the damped silent switch more precise and smooth.

[0049] More specifically, the bottom end of the damping shaft 13 is linked to a positioning end 134 embedded in the positioning blind hole 115. The positioning end 134 is rotatably engaged with the positioning blind hole 115, and the positioning end 134 is detachably adapted to the damping shaft 13. This positioning end 134 can be detachably connected to the bottom end of the damping shaft 13 so that when the positioning end 134 wears out after frequent use, it can be removed from the main structure of the damping shaft 13 and replaced with a new positioning end 134 in a timely manner. This ensures that the rotational engagement between the damping shaft 13 and the positioning blind hole 115 remains smooth and efficient, thereby making the switching operation of the damped silent switch smoother and more fluid.

[0050] Furthermore, in practical applications, the positioning blind hole 115 can be a spherical hole, and the positioning end 134 can be a spherical end arranged concentrically with and rotatably adapted to the positioning blind hole 115. Thus, by utilizing the spherical fitting structure between the spherical end and the spherical hole, the rotational fit between the positioning end 134 and the positioning blind hole 115 can be further optimized, making the rotation of the positioning end 134 within the positioning blind hole 115 smoother and more fluid. This, in turn, optimizes the fixed-axis rotation efficiency of the damping shaft 13, thereby making the operation of the damped silent switch smoother and more efficient.

[0051] Furthermore, a positioning ring groove 135 is recessed on the outer peripheral wall of the damping shaft 13, and the damping ring 133 is coaxially embedded in the positioning ring groove 135. The positioning ring groove 135 can provide sufficient assembly space and axial structural limit for the damping ring 133, so as to further improve the assembly integration between the damping ring 133 and the main structure of the damping shaft 13, optimize the linkage effect between the damping shaft 13 and the damping ring 133 during rotation, thereby enabling the frictional resistance between the damping ring 133 and the damping groove 114 to be transmitted more smoothly and fully through the damping shaft 13 and the linkage plate 131 to the silver point rocker 12, thereby optimizing the buffering effect on the silver point rocker 12 and making the operation of the damped silent switch quieter and smoother.

[0052] On the other hand, a linkage lug 136 connects the outer wall of the damping shaft 13 and the linkage mounting plate 131. The width of the linkage lug 136 increases from top to bottom, and the linkage mounting plate 131 is linked to the lower outer wall of the linkage lug 136. The variable width structure of the linkage lug 136 itself can further optimize the stress distribution between the damping shaft 13 and the linkage mounting plate 131, thereby providing a more stable structural support for the linkage mounting plate 131 and optimizing the linkage effect between the damping shaft 13 and the linkage mounting plate 131, making the rotation adaptation process of the entire component smoother and more reliable.

[0053] Generally, the linkage slot 132 is a U-shaped slot with its opening facing the silver dot rocker 12. Generally, the linkage slot 132 is arranged on one side of the silver dot rocker 12, and its opening orientation can be consistent with the axial direction of the reference side shaft 121. Of course, the linkage slot 132 can also be arranged above or at the top corner of the silver dot rocker 12. In principle, as long as it can contact and adapt with the end of the silver dot rocker 12 away from the reference side shaft 121, and avoid structural interference with functional components such as the drive spring 102, it is acceptable.

[0054] In addition, an anti-slip pad 116 is provided on the bottom inner wall of the electrical box 11, which contacts and rolls to fit the reference side shaft 121. This anti-slip pad 116 is generally a plastic or rubber pad, but other materials such as engineering plastics can be used as pads or coverings depending on the working conditions and processing costs. Using this anti-slip pad 116 as a mating component that directly contacts the reference side shaft 121 prevents the silver dot rocker 12 from loosening or misaligning during rotation, ensuring the rotational tracking and stability of the silver dot rocker 12, and making the contact and conduction between the trigger terminal 122 and the corresponding wiring terminal 112 more accurate, smooth, and reliable.

[0055] In summary, the damped silent switch provided in this utility model, during its operation, is operated by the user pressing a button to rotate the silver dot rocker plate around a reference axis. This causes the silver dot rocker plate to rotate from its position matching one set of terminals to its position matching another set of terminals, thereby causing the trigger terminal to act accordingly. This enables the trigger terminal to conduct or separate from the terminals that connect or disconnect the switch circuit, thus realizing the switching operation of the damped silent switch. During this period, when the silver rocker swings around the reference axis in accordance with the button's action, it will first contact and abut against the inner wall of the linkage slot. Then, the silver rocker continues to move, driving the linkage plate to swing synchronously through the abutment transmission between it and the inner wall of the linkage slot. At this time, the damping shaft rotates synchronously on the fixed axis with the linkage plate. Due to the friction fit structure between the damping shaft and the damping groove, the damping shaft will be subject to frictional resistance from the outer wall and the inner wall of the damping groove during its fixed axis rotation, thus slowing down the rotation speed of the damping shaft. In this way, the abutment linkage between the linkage slot and the silver rocker transmits the resistance to the silver rocker, thereby slowing down the swing speed of the silver rocker and allowing it to continue swinging more smoothly until the silver rocker contacts the target terminal on the other side. Therefore, by utilizing the frictional resistance between the damping shaft and the damping groove, the structural impact during the swing of the silver point rocker is effectively mitigated, and a large impact is avoided when the silver point rocker comes into contact with the terminal block. This significantly reduces the noise when the silver point rocker comes into contact with the terminal block, thereby significantly reducing the overall noise when the button and other moving parts of the damped silent switch are triggered, making the operation of the damped silent switch quieter and smoother.

Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
