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 flexible speed-reducing 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 components, 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 silent switch 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 flexible speed-reducing silent switch, which produces less noise when the components work together during the switching operation, making the operation of the flexible speed-reducing silent switch quieter.

[0007] To solve the above-mentioned technical problems, this utility model provides a flexible speed reduction silent switch, including a panel, a button located at the front of the panel, an electrical box located at the rear of the panel, and a pressure plate installed between the panel 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 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 to the button through a drive arm 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 buffer is fixedly provided in the middle of the pressure plate. The bottom end of the buffer has two buffer arms that can abut against the top of the silver point rocker and elastically deform along the swing direction of the silver point rocker. The two buffer arms are symmetrically arranged on both sides of the silver point rocker along the swing direction of the silver point rocker.

[0010] Preferably, the buffer further includes a positioning seat fixedly connected to the middle of the pressure plate, the buffer arm is connected to the bottom of the positioning seat, and the two buffer arms are fitted with a gap to form a positioning groove for the silver dot rocker to be inserted.

[0011] Along the swing direction of the silver dot rocker, the width of the positioning groove is greater than the thickness of the silver dot rocker.

[0012] Preferably, the buffer arm includes a buffer stop bar and a deformation segment, the deformation segment being connected between the top end of the buffer stop bar and the bottom end of the positioning seat, and the deformation segment being able to elastically deform along the swing direction of the silver dot rocker.

[0013] Preferably, the deformation segment is a U-shaped arc plate with its opening facing the silver dot rocker, the positioning seat and the buffer strip are respectively connected to the two ends of the opening of the deformation segment, and the distance between the two buffer strips decreases from the end away from the silver dot rocker to the end close to the silver dot rocker.

[0014] Preferably, the bottom of the pressure plate is recessed with a positioning hole, and the positioning seat is fixedly inserted into the positioning hole in a direction perpendicular to the reference side axis.

[0015] Preferably, a positioning bracket is provided on the inner wall of the positioning hole opening, and the free end of the positioning bracket abuts against the outer wall of the positioning seat;

[0016] A positioning latch protrudes from the outer wall of the positioning seat. The positioning platform is located between the positioning latch and the silver dot rocker plate, and the end face of the positioning latch facing the silver dot rocker plate abuts against the end face of the positioning platform facing away from the silver dot rocker plate.

[0017] Preferably, the thickness of the positioning tongue increases from the end furthest from the positioning platform to the end closest to the positioning platform.

[0018] Preferably, the positioning seat is a U-shaped arc plate with its opening facing the silver dot rocker, and the two buffer arms are respectively connected to the two ends of the opening of the positioning seat.

[0019] Preferably, the buffer is a one-piece molded part.

[0020] Preferably, the buffer is a plastic part.

[0021] Compared to the aforementioned background technology, the flexible speed-reducing silent switch provided by this utility model, during operation, is operated by the user pressing a button to drive the silver dot rocker plate to rotate around the reference side axis via the drive arm assembly. This causes the silver dot rocker plate to rotate from the position that matches one set of terminal blocks to the position that matches another set of terminal blocks, thereby causing 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 flexible speed-reducing silent switch. During this period, when the silver rocker swings around the reference axis with the action of the button, it will first contact and abut against the buffer arm that is closer to the target terminal among the two buffer arms. Then, the silver rocker continues to swing with the action of the button and the drive arm assembly. At this time, the buffer arm is subjected to the abutting pressure from the silver rocker and undergoes moderate elastic deformation. At the same time, it slowly moves in the same direction as the swing of the silver rocker. Since the elastic deformation of the buffer arm provides elastic resistance to the silver rocker in the opposite direction of its swing, the buffer arm can be used to form a moderate structural buffer and jamming on the silver rocker, and effectively slow down the swing rate of the silver rocker, so that the silver rocker can continue to swing more smoothly until the silver rocker contacts the target terminal. Therefore, by utilizing the elastic resistance generated by the buffer arm itself when it is compressed and undergoes elastic deformation after contacting the silver point rocker, the structural impact during the swing of the silver point rocker is effectively mitigated, and large impacts are avoided when the silver point rocker contacts the terminal block. This significantly reduces the noise when the silver point rocker contacts the terminal block, and consequently significantly reduces the overall noise when the button and other moving parts of the elastic speed reduction silent switch are triggered, making the operation of the elastic speed reduction silent switch quieter and smoother.

[0022] In another preferred embodiment of this utility model, the buffer further includes a positioning seat fixedly connected to the middle of the pressure plate, and the buffer arm is connected to the bottom of the positioning seat. The two buffer arms are fitted with a gap to form a positioning groove for the silver dot rocker to be inserted. Along the swing direction of the silver dot rocker, the width of the positioning groove is greater than the thickness of the silver dot rocker. The positioning seat, as an assembly part directly connected to the pressure plate, provides sufficient and reliable structural support and a positioning foundation for the entire buffer, preventing structural loosening or misalignment due to force on the buffer arm during use, and ensuring the fitting accuracy between the buffer arm and the silver dot rocker. Based on this, the positioning groove can form a pre-alignment fit with the silver dot rocker, ensuring that the silver dot rocker is always within the positioning groove after the assembly is in place. At this time, the outer wall of the buffer arm facing the silver dot rocker is the inner wall of the positioning groove. During the movement of the silver dot rocker, it contacts and abuts against the inner wall of the positioning groove, thereby forming a structural buffer for the silver dot rocker through the elastic deformation of the buffer arm. Furthermore, the width of the positioning groove is greater than the thickness of the silver dot rocker, which ensures that there is a suitable structural clearance between the silver dot rocker and the side wall of the positioning groove. This allows the silver dot rocker to swing from one terminal to the other without contacting the buffer arm in the initial swing path, thus ensuring a smoother and more fluid feel when pressing the button of the elastic speed reduction silent switch. After the silver dot rocker continues to swing until it comes into contact with the buffer arm near the other terminal, it forms a buffer and resistance to the swing of the silver dot rocker, thereby reducing the structural impact when the silver dot rocker swings to the target terminal and making the operation of the switching device quieter and gentler.

[0035] The core of this utility model is to provide a flexible speed-reducing silent switch. During the switching operation of this flexible speed-reducing silent switch, the noise generated when the components cooperate is small, making the operation of the flexible speed-reducing silent switch relatively quiet.

[0036] 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.

[0037] 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.

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.

[0040] In specific implementation methods, in conjunction with references Figures 1 to 5 As shown, the flexible speed-reducing silent switch provided by this utility model includes a panel 10, a button 101 located at the front of the panel 10, an electrical box 11 located at the rear of the panel 10, and a pressure plate 13 installed between the panel 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 gap-fitted to form a trigger groove 113 between the two terminal groups 111.

[0041] 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 the drive arm assembly 102 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.

[0042] A buffer 14 is fixedly provided in the middle of the pressure plate 13. Two buffer arms 141 protrude from the bottom end of the buffer 14 and can abut against the top of the silver point rocker 12 and elastically deform along the swing direction of the silver point rocker 12. The two buffer arms 141 are symmetrically arranged on both sides of the silver point rocker 12 along the swing direction of the silver point rocker 12.

[0043] For ease of understanding, and as a reference, taking a flexible speed-reducing silent switch installed on a wall to control the opening or closing of electrical appliances such as lights as an example, the electrical box 11 is embedded in the switch mounting hole on the wall; the pressure plate 13 is aligned and fastened in the mounting hole, and the pressure plate 13 can be a frame structure or a regular or irregular plate structure; the panel 10 is installed on the wall surface and aligned on the pressure plate 13, and the panel 10 is usually a frame structure; the button 101 is installed in the frame structure of the panel 10; the drive arm assembly 102 usually includes a drive arm body 103 with a hollow structure and a drive spring 104 inserted into the cavity of the drive arm body 103. The drive arm body 103 passes through the middle of the pressure plate 13 so as to be linked and connected with the button 101 and the rocker arm 12 and other moving parts inside the electrical box 11; the buffer 14 is arranged on one side of the drive arm assembly 102. Accordingly, the main extension surface of panel 10, the bottom inner wall of electrical box 11, and the wall surface are parallel to each other. Unless otherwise specified, the descriptions of the relative positions and arrangement directions of components in the rest of this document can be understood by referring to the corresponding descriptions here, and will not be repeated here.

[0044] During specific equipment operation, the user presses button 101 to drive the silver dot rocker 12 to rotate around the reference side shaft 121 via the drive arm assembly 102. This causes the silver dot rocker 12 to rotate from its position matching one set of terminal blocks 111 to its position matching another set of terminal blocks 111, thereby driving the trigger terminal 122 to move accordingly. This enables the trigger terminal 122 to conduct or separate from the terminal block 112 that connects or disconnects the switch circuit, thus realizing the switching operation of the elastic speed reduction silent switch. During this period, when the silver dot rocker 12 swings around the reference side axis 121 with the action of the button 101, it will first contact and abut against the buffer arm 141 that is closer to the target terminal 112. Then, the silver dot rocker 12 continues to swing with the action of the button 101 and the drive arm assembly 102. At this time, the buffer arm 141 is subjected to the abutting pressure from the silver dot rocker 12 and undergoes moderate elastic deformation. At the same time, it slowly moves in the same direction as the swing of the silver dot rocker 12. Since the elastic deformation of the buffer arm 141 provides elastic resistance to the silver dot rocker 12 in the opposite direction of its swing, the buffer arm 141 can be used to form a moderate structural buffer and jamming on the silver dot rocker 12 and effectively slow down the swing rate of the silver dot rocker 12, so that the silver dot rocker 12 can continue to swing more smoothly until the silver dot rocker 12 contacts the target terminal 112. Therefore, by utilizing the elastic resistance generated by the buffer arm 141 itself when it is compressed and undergoes elastic deformation after contacting the silver dot rocker 12, the structural impact during the swinging process of the silver dot rocker 12 is effectively mitigated, and a large impact is avoided 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, and further significantly reduces the overall noise when the button 101 and other moving parts of the elastic speed reduction silent switch are activated, so that the operation of the elastic speed reduction silent switch is quieter and smoother.

[0045] It is easy to understand that, as shown in the figure, the flexible speed-reducing silent switch in this solution can be a multi-control flexible speed-reducing silent switch, a dual-channel reversing flexible speed-reducing silent switch, or other flexible speed-reducing silent switches 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 flexible speed-reducing silent switch, 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 and linkage components such as the linkage plate in this solution, and meets the actual application needs of the flexible speed-reducing silent switch, is acceptable.

[0046] Accordingly, the linkage connection between button 101 and the silver dot rocker 12 can be achieved through a drive spring 104 located in the inner cavity of the drive arm body 103 and connected between button 101 and silver dot rocker 12, as shown in the figure, in conjunction with a linkage connector 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 actual application needs of the elastic speed-reducing silent switch is acceptable.

[0047] Specifically, the buffer 14 also includes a positioning seat 142 fixedly connected to the middle of the pressure plate 13, a buffer arm 141 connected to the bottom of the positioning seat 142, and the two buffer arms 141 are fitted with a gap to form a positioning groove 143 for the silver dot rocker 12 to be inserted; along the swing direction of the silver dot rocker 12, the width of the positioning groove 143 is greater than the thickness of the silver dot rocker 12.

[0048] As an assembly part directly connected to the pressure plate 13, the positioning seat 142 provides sufficient and reliable structural support and positioning foundation for the entire buffer 14, preventing structural loosening or misalignment of the buffer arm 141 due to stress during use, and ensuring the fitting accuracy between the buffer arm 141 and the silver dot rocker 12. Based on this, the positioning groove 143 can form a pre-alignment fit with the silver dot rocker 12, ensuring that the silver dot rocker 12 remains within the positioning groove 143 after assembly. At this time, the outer wall of the buffer arm 141 facing the silver dot rocker 12 is the inner wall of the positioning groove 143. During the movement of the silver dot rocker 12, it contacts and abuts against the inner wall of the positioning groove 143, thus providing structural cushioning for the silver dot rocker 12 through the elastic deformation of the buffer arm 141.

[0049] Furthermore, the width of the positioning groove 143 is greater than the thickness of the silver dot rocker 12, which ensures that there is a suitable structural clearance between the silver dot rocker 12 and the side wall of the positioning groove 143. This allows the silver dot rocker 12 to swing from one terminal 112 to the other terminal 112 without contacting the buffer arm 141 in the initial swing path. This ensures a smoother and more fluid feel when the button 101 of the elastic speed reduction silent switch is pressed. After the silver dot rocker 12 continues to swing until it comes into contact with the buffer arm 141 near the other terminal 112, it forms a buffer and resistance to the swing of the silver dot rocker 12, thereby reducing the structural impact when the silver dot rocker 12 swings to the target terminal 112, making the operation of the switching device quieter and gentler.

[0050] Generally, the buffer 14 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 component processing difficulty and overall application cost of the elastic speed reduction silent switch.

[0051] More specifically, the buffer arm 141 includes a buffer stop 144 and a deformation section 145. The deformation section 145 is connected between the top end of the buffer stop 144 and the bottom end of the positioning seat 142, and the deformation section 145 can elastically deform along the swing direction of the silver dot rocker 12. Thus, the deformation section 145 is used as the main elastic deformation part of the buffer arm 141 to optimize the overall structural strength and stress distribution of the buffer arm 141. Generally, the buffer stop 144 can also be made of an elastic material with a certain elastic deformation capacity to further improve the structural impact resistance of the buffer arm 141 and its buffering and damping effect on the silver dot rocker 12, thereby further reducing or even avoiding noise generated during the operation of the silver dot rocker 12, so as to make the operation of the elastic deceleration silent switch quieter.

[0052] Based on this, the deformation section 145 is a U-shaped arc plate with its opening facing the silver dot rocker plate 12. The positioning seat 142 and the buffer strip 144 are respectively connected to the two ends of the opening of the deformation section 145, and the distance between the two buffer strips 144 decreases from the end away from the silver dot rocker plate 12 to the end closer to the silver dot rocker plate 12. The variable-pitch fit structure formed between the two buffer strips 144 can optimize the contact angle between the buffer strip 144 and the silver dot rocker plate 12, so that the stress distribution when the buffer strip 144 and the silver dot rocker plate 12 abuts is more uniform and reliable. In addition, the inclined buffer strip 144 can better adapt to the U-shaped extension structure of the deformation section 145 itself, making the connection structure between the buffer strip 144 and the deformation section 145 more regular and compact, and thus optimizing the stress resistance of the buffer member 14.

[0053] Furthermore, a positioning hole 131 is recessed at the bottom of the pressure plate 13, and the positioning seat 142 is fixedly inserted into the positioning hole 131 along a direction perpendicular to the reference side axis 121. The positioning hole 131 can provide stable structural limit and appropriate structural support for the positioning seat 142 to ensure the overall structural strength and fitting accuracy of the buffer 14 during operation. Arranging the positioning hole 131 at the bottom of the pressure plate 13 helps to optimize the utilization rate of the internal assembly space and the component assembly integration of the flexible speed reduction silent switch, so as to make the overall assembly mechanism of the flexible speed reduction silent switch more compact and reliable.

[0054] Furthermore, a positioning platform 132 protrudes from the inner wall of the positioning hole 131, and the free end of the positioning platform 132 abuts against the outer wall of the positioning seat 142. A positioning tongue 146 protrudes from the outer wall of the positioning seat 142, and the positioning platform 132 is located between the positioning tongue 146 and the silver dot rocker plate 12, with the end face of the positioning tongue 146 facing the silver dot rocker plate 12 abutting against the end face of the positioning platform 132 facing away from the silver dot rocker plate 12. The mating structure of the free end of the positioning platform 132 abutting against the outer wall of the positioning seat 142 forms radial and circumferential limiting of the positioning seat 142; the end face abutting mating between the positioning tongue 146 and the positioning platform 132 forms axial limiting of the positioning seat 142. This further improves the assembly strength between the positioning seat 142 and the positioning hole 131, ensuring the structural stability of the buffer 14 during the operation of the switch device. This optimizes the matching accuracy between the buffer 14 and the silver dot rocker 12, and makes the buffer resistance transmission of the buffer 14 to the silver dot rocker 12 more stable and reliable, thus further optimizing the quietness of the switch operation.

[0055] Furthermore, the thickness of the positioning tongue 146 increases from the end furthest from the positioning platform 132 to the end closest to the positioning platform 132. This gives the positioning tongue 146 a variable thickness structure that is narrower at the top and wider at the bottom, further optimizing the stress distribution when the positioning tongue 146 abuts against the positioning platform 132, improving the stress resistance and structural strength of the positioning tongue 146, and ensuring the positioning effect of the corresponding positioning seat 142 and the overall assembly stability of the buffer 14.

[0056] In fact, if the buffer 14 is integrated with a positioning tab 146 and a deformation section 145 with a U-shaped arc plate structure, the arc top of the deformation section 145 can abut against the end face of the positioning platform 132 facing the silver dot rocker plate 12. Thus, the arc top of the deformation section 145 and the positioning tab 146 cooperate to abut against the two end faces of the positioning platform 132 respectively, forming a reliable bidirectional clamping of the positioning platform 132. This further improves the assembly strength between the buffer 14 and the positioning hole 131, ensuring that the position of the buffer 14 remains constant during the operation of the device, thereby correspondingly improving the fitting accuracy between the buffer 14 and the silver dot rocker plate 12 and other mating parts.

[0057] Furthermore, the positioning seat 142 is a U-shaped arc plate with its opening facing the silver dot rocker 12, and two buffer arms 141 are respectively connected to the two ends of the opening of the positioning seat 142. Similar to the U-shaped arc plate structure of the deformation section 145 mentioned above, the positioning seat 142 is also a U-shaped arc plate structure, so as to utilize the appropriate opening and closing of the U-shaped arc plate structure itself to form elastic deformation, thereby achieving the corresponding structural buffering effect and providing a stable and reliable elastic force as elastic resistance to the swinging process of the silver dot rocker 12.

[0058] On the other hand, in practical applications, the buffer component 14 is a one-piece molded part. That is, the positioning seat 142, buffer strip 144, deformation section 145, and positioning latch 146 mentioned in the above scheme can all be processed into one-piece structural parts to ensure the overall structural strength of the buffer component 14 and simplify its processing flow. Generally, if the buffer component 14 is made of plastic or engineering plastic, the various parts of the buffer component 14 can be integrally processed and molded through injection molding.

[0059] In summary, the flexible speed-reducing silent switch provided in this utility model, during its operation, is operated by the user pressing a button to drive the silver dot rocker plate to rotate around the reference side axis via the drive arm assembly. This causes the silver dot rocker plate to rotate from the position that matches one set of terminal blocks to the position that matches another set of terminal blocks, thereby causing the trigger terminal to act accordingly. This enables the trigger terminal to conduct or separate from the terminal block that connects or disconnects the switch circuit, thus realizing the switching operation of the flexible speed-reducing silent switch. During this period, when the silver rocker swings around the reference axis with the action of the button, it will first contact and abut against the buffer arm that is closer to the target terminal among the two buffer arms. Then, the silver rocker continues to swing with the action of the button and the drive arm assembly. At this time, the buffer arm is subjected to the abutting pressure from the silver rocker and undergoes moderate elastic deformation. At the same time, it slowly moves in the same direction as the swing of the silver rocker. Since the elastic deformation of the buffer arm provides elastic resistance to the silver rocker in the opposite direction of its swing, the buffer arm can be used to form a moderate structural buffer and jamming on the silver rocker, and effectively slow down the swing rate of the silver rocker, so that the silver rocker can continue to swing more smoothly until the silver rocker contacts the target terminal. Therefore, by utilizing the elastic resistance generated by the buffer arm itself when it is compressed and undergoes elastic deformation after contacting the silver point rocker, the structural impact during the swing of the silver point rocker is effectively mitigated, and large impacts are avoided when the silver point rocker contacts the terminal block. This significantly reduces the noise when the silver point rocker contacts the terminal block, and consequently significantly reduces the overall noise when the button and other moving parts of the elastic speed reduction silent switch are triggered, making the operation of the elastic speed reduction silent switch quieter and smoother.

[0060] The above provides a detailed description of the flexible speed-reducing silent switch provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
