Description

Technical Field

[0001] The present invention relates to the field of electrical devices, and in particular to a switch. Background Art

[0002] A switch is an electrical device used to connect and disconnect a circuit. The switch is turned by pressing the panel to connect or disconnect the circuit.

[0003] In switches provided by related technologies, a panel snaps directly onto the top of a transition piece, which is hinged to a pressure plate. A pin assembly is connected to the bottom of the transition piece. When the panel is pressed and rotated, it drives the transition piece to rotate around the pressure plate. The rotating transition piece, in turn, drives the pin assembly to move the seesaw, causing the moving contact on the seesaw to contact or separate from the stationary contact, thereby turning the switch on or off.

[0004] However, in the related art, if the pin assembly is to fully move the rocker, the rotation stroke of the panel must be large enough, which results in a heavier feel when the switch is turned. Summary of the Invention

[0014] In some possible implementations, the track groove includes a first track groove wall abutting against the slider, the first track groove wall including: an upward movement amplitude control section and two swing amplitude control sections, the two swing amplitude control sections being symmetrically arranged on both sides of the upward movement amplitude control section;

[0015] The upward movement amplitude control section is used to control the upward translation distance of the transition piece;

[0016] The swing amplitude control section is used to control the swing amplitude at the swing starting position and the swing ending position of the transition piece.

[0017] In some possible implementations, the track groove further includes a second track groove wall, and the second track groove wall cooperates with the first track groove wall, so that the track groove is a closed groove.

[0018] In some possible implementations, the wall of the slider that contacts the wall of the first track groove is arc-shaped.

[0019] In some possible implementations, the toggle slot includes two toggle slot side walls that are arranged opposite to each other, and the toggle slot side walls are arranged in a vertical plane;

[0020] The movable connecting block has two arc-shaped side portions that are arranged opposite to each other, and the arc-shaped side portions respectively abut against the corresponding side walls of the toggle slot.

[0021] In some possible implementations, the fixing member further has a rotation groove, and the transition member further has a limit block;

[0022] The limit block is located in the rotation groove, and the rotation groove is used to limit the position of the virtual rotation axis, so that the transition piece rotates around the virtual rotation axis and allows the limit block to move up and down.

[0023] In some possible implementations, the rotation groove includes oppositely arranged rotation groove side walls, and both of the rotation groove side walls are arc-shaped and convex toward each other;

[0024] The wall of the limiting block in contact with the side wall of the rotation groove is arranged in a vertical plane.

[0025] In some possible implementations, the slider is located below the virtual rotation axis.

[0026] In some possible implementations, the track groove includes a first track groove wall abutting against the slider, the first track groove wall including: an upward movement amplitude control section and two swing amplitude control sections, the two swing amplitude control sections being symmetrically arranged on both sides of the upward movement amplitude control section;

[0027] The upward movement amplitude control section is in an arc-shaped convex shape, and the swing amplitude control section is in an arc-shaped concave shape.

[0028] In some possible implementations, the slider is located at a lower portion of the transition piece;

[0034] The solution provided by the embodiment of the present invention has at least the following effects:

[0035] The switch provided by the embodiments of the present invention differs from conventional shaft-constrained transition pieces by innovatively utilizing a track-constrained transition piece. During the dialing process of this switch, pressing the panel causes the dialing slot to drive the movable connecting block to rotate, thereby causing the transition piece to rotate as a whole. Because the slider provided on the transition piece is guided by the track slot and can move up and down, the transition piece can also move up and down as a whole during the rotation process. As a result, the upward movement of the transition piece during rotation reduces the compression of the spring of the ball assembly, thereby reducing the compression force on the spring during the dialing process and lowering the amount of spring compression, thereby reducing the switch dialing force. Furthermore, by adjusting the positions of the starting and ending points of the track defined by the track slot, the position of the transition piece at the starting and ending points of its swing is controlled, allowing the transition piece to maintain a desired swing amplitude when the switch is stationary. This increases the amount of spring compression when the switch is stationary, ensuring sufficient contact pressure between the moving and stationary contacts and enhancing the electrical performance of the switch.

[0063] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0064] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0065] The directional terms used in the embodiments of the present invention, such as "upper," "lower," and "side," are based on the assembled state of the switch. These directional terms are used only to more clearly describe the relationship between structures and are not intended to describe absolute directions. Specifically, the direction where the switch panel is located is referred to as "upper" or "top," while the direction where the switch's functional module is located is referred to as "lower" or "bottom."

[0066] In the embodiment of the present invention, the “stationary state of the switch” involved includes the energized state and the disconnected state of the switch. In the stationary state, all movable components in the switch are in a stationary state.

[0067] In the rocker switch provided by the related art, if the pin assembly is to move the rocker to the right position, the rotation stroke of the panel must be large enough, which causes the switch to have a heavier dialing feel, affecting the user experience.

[0068] In order to reduce the force of dialing a switch and improve the hand feeling, an embodiment of the present invention provides a switch, as shown in the attached Figure 1 and attached Figure 2 As shown, the switch includes: a panel 1, a fixing member 2, a transition member 3, a ball assembly 5, a housing assembly 4 and a functional module 6; the panel 1 is hinged to the housing assembly 4, and the panel 1 has a toggle slot 10 (see Figure 3 ); The fixing member 2 is fixedly connected to the housing assembly 4, and the fixing member 2 has a track groove 21 (see Figure 4 and Figure 5 ); The transition piece 3 acts on the functional module 6 through the pin assembly 5, and the transition piece 3 has a slider 31 and an active connecting block 32 (see Figure 6 ).

[0069] In particular, the slider 31 is located in the track groove 21 , and the track groove 21 is used to enable the slider 31 to move up and down while rotating.

[0070] The movable connecting block 32 is located in the toggle slot 10 , and the toggle slot 10 is used to toggle the movable connecting block 32 to rotate and allow the movable connecting block 32 to move up and down.

[0071] The “up and down movement” mentioned above refers to movement toward and away from the panel 1 , wherein upward movement is to approach the panel 1 , and downward movement is to move away from the panel 1 .

[0072] Functional module 6 is fixed to fixture 2 and includes at least a seesaw, an incoming terminal assembly, and an outgoing terminal assembly. The incoming terminal assembly includes a support member that is movably connected to the bottom of the seesaw to allow the seesaw to swing. The outgoing terminal assembly includes a static contact that is configured to contact a corresponding moving contact on the seesaw.

[0073] The ball assembly 5 includes a ball 51 and a spring 52. The ball 51 is connected to the transition piece 3 and abuts against the top of the seesaw to drive the seesaw to swing. The spring 52 is located between the ball 51 and the transition piece 3 and is used to reset the ball 51.

[0074] When the user operates the switch to switch between the power-on state and the power-off state, the panel 1 is pressed to rotate. The rotating panel 1 transmits the driving force to the ball assembly 5 through the moving transition piece 3. The ball 51 slides left and right on the seesaw, and then moves the seesaw to swing. The swinging seesaw drives the moving contact to contact or separate with the corresponding static contact, thereby achieving the purpose of switching the current on and off.

[0075] As the pin 51 moves the seesaw, the spring 52 is simultaneously compressed. Research has found that the dialing force of the switch primarily comes from the compression force of the spring 52, which is generated by the constantly changing compression of the spring 52 of the pin assembly 5 during the dialing process. Therefore, by reducing the compression of the spring 52, and thereby reducing the compression force of the spring 52, the dialing force can be effectively reduced. However, simply reducing the compression of the spring 52 will reduce the contact pressure between the moving contact and the static contact on the seesaw when the switch is in the static state, which can lead to increased contact resistance, arcing, and other problems. Therefore, it is necessary to reduce the compression of the spring 52 during the dialing process while ensuring that the moving and static contacts obtain a greater contact pressure.

[0076] The switch provided by the present invention differs from conventional shaft-constrained transition piece 3 by innovatively utilizing a track-constrained transition piece 3. During the dialing process of this switch, pressing the panel 1 causes the toggle slot 10 to drive the movable connecting block 32, causing it to rotate, thereby causing the transition piece 3 to rotate as a whole. Because the slider 31 provided on the transition piece 3 can move up and down under the guidance of the track slot 21, the transition piece 3 can also move up and down as a whole during the rotation process. The upward movement of the transition piece 3 during rotation reduces the compression of the spring 52 of the ball assembly 5, thereby reducing the compression force on the spring 52 during the switch dialing process and reducing the amount of spring 52 compression, thereby reducing the switch dialing force. Furthermore, by adjusting the starting and ending positions of the track defined by the track slot 21, the position of the transition piece 3 at the starting and ending points of its swing is controlled, allowing the transition piece 3 to maintain a desired swing amplitude when the switch is stationary. This increases the amount of spring 52 compression when the switch is stationary, ensuring sufficient contact pressure between the moving and stationary contacts and enhancing the electrical performance of the switch.

[0077] It can be seen that the switch provided by the embodiment of the present invention ensures that the transition piece 3 translates upward while rotating through the cooperation of the track groove 21 and the toggle groove 10, thereby reducing the compression of the spring 52 during the toggle process and thereby reducing the toggle force.

[0078] The following is an exemplary description of the cooperation between the track groove 21 and the slider 31:

[0079] See also Figure 7 The track groove 21 is provided on the fixing part 2, and its position is fixed to constrain the movement of the slider 31 therein, thereby controlling the swinging track of the transition part 3, so that the transition part 3 moves up and down while rotating, thereby achieving the purpose of reducing the compression amount of the spring 52 during the swinging process of the transition part 3.

[0080] In some examples, such as the attached Figure 7As shown, the fixing member 2 has a receiving cavity 23, which is used to accommodate the transition member 3. A through hole of a certain shape can be set on the wall of the receiving cavity 23 at the position corresponding to the slider 31. The through hole serves as a track groove 21. For example, a track groove 21 is respectively set on the two opposite side walls of the receiving cavity 23.

[0081] Understandably, for a rocker switch, as the panel 1 is pressed, the switch remains stationary in the initial stages of the press due to deformation of the plastic components and the overcoming of gaps between components. This occurs until the force applied to the panel 1 reaches the dialing point, at which point the switch transitions from a stationary state to a moving state. At this point, the transition piece 3 begins to swing, its corresponding position becoming the swinging start point, and the spring 52 of the ball assembly 5 begins to compress. As the dialing force continues to increase until it reaches its peak, the transition piece 3 swings to its swinging end point, completing the rocker's flip and instantly returning the spring 52 to its original position.

[0082] In some examples, such as the attached Figure 8 As shown, the track groove 21 includes a first track groove wall 211 abutting against the slider 31 , and the first track groove wall 211 includes: an upward movement amplitude control section 2111 and two swing amplitude control sections 2112 , and the two swing amplitude control sections 2112 are symmetrically arranged on both sides of the upward movement amplitude control section 2111 .

[0083] The two ends of the upward movement amplitude control section 2111 are respectively connected to two swing amplitude control sections 2112. The upward movement amplitude control section 2111 is used to control the upward translation distance of the transition piece 3. The swing amplitude control section 2112 is used to control the swing amplitude of the transition piece 3 at the swing starting position and the swing end position.

[0084] The structure of the track groove 21 is set in this way, so that the compression force of the spring 52 remains unchanged when the switch is in a static state, and the pressure during the dialing process is reduced.

[0085] The upward movement distance of the slider 31 is determined by adjusting the longitudinal height of the upward movement amplitude control section 2111 , and the starting position and the end position of the upward sliding movement are determined by adjusting the arc length of the upward movement amplitude control section 2111 .

[0086] It can be understood that the slider 31 moves up and down along one side of the upward amplitude control section 2111 to the highest point, so that the reduction value of the compression amount of the spring 52 also reaches the maximum. Then, the slider 31 moves downward from the highest point along the other side of the upward amplitude control section 2111 to its lowest point, and the compression amount of the spring 52 gradually increases, so as to increase the contact pressure between the moving and static contacts when the switch is in a static state.

[0087] The swing track of the slider 31 can be located below the virtual axis or above it. For example, when the swing track of the slider 31 is located below the virtual axis, in this case, see Figure 8 The first track groove wall 211 is the lower wall of the track groove 21, the upward movement amplitude control section 2111 is an arc-shaped convex shape, and the swing amplitude control section 2112 is an arc-shaped concave shape. Among them, the upward movement amplitude control section 2111 is located above the swing amplitude control section 2112.

[0088] For example, when the swing track of the slider 31 is located above the virtual axis, in this case, see Figure 11 The first track groove wall 211 is the upper wall of the track groove 21, the upward movement amplitude control section 2111 is an arc-shaped convex shape, the swing amplitude control section 2112 is also an arc-shaped convex shape, and the upward movement amplitude control section 2111 is convexly arranged above the swing amplitude control section 2112.

[0089] Combine Figure 8 and Figure 10 , the motion trajectory of the slider 31 on the first track groove wall 211 is exemplarily described in the case where the swing trajectory of the slider 31 is located below the virtual rotation axis:

[0090] The lower part of the slider 31 overlaps the first track groove wall 211, wherein the swing amplitude control section 2112 is a concave arc, and the swing amplitude control section 2112 is used to control the swing amplitude of the transition piece 3 at the swing starting position and the swing ending position to ensure that the compression amount of the spring 52 is large enough at the swing starting position and the swing ending position, so that there is sufficient contact pressure between the moving contact and the static contact.

[0091] The upward movement amplitude control section 2111 is an upward convex arc, and is used to control the upward translation distance of the transition piece 3 during the swinging process. In addition, the upward movement amplitude control section 2111 is located between the two swinging amplitude control sections 2112.

[0092] Then, combined Figure 10 It can be seen that the slider 31 moves from the swing amplitude control section 2112 on one side along the side of the upward amplitude control section 2111. When it moves to the highest point, the upward distance of the slider 31 reaches the maximum, and the compression of the spring 52 reaches the minimum. Then, the slider 31 moves downward from the highest point along the other side of the upward amplitude control section 2111 until it enters the swing amplitude control section 2112 on the other side. The compression of the spring 52 gradually increases. When the transition piece 3 reaches the end position of the swing, due to the constraint of the swing amplitude control section 2112, the compression of the spring 52 increases to the target value to maintain a sufficiently large contact pressure between the moving and static contacts.

[0093] In some examples, when the switch is in a static state, the compression amount of the spring 52 of the pin assembly 5 is expected to be a target value, which can be comparable to the compression amount of the spring 52 of a traditional rocker switch in a static state, for example, the target value can be the same.

[0094] Further, see Figure 8 The track groove 21 further includes a second track groove wall 212 , which cooperates with the first track groove wall 211 , so that the track groove 21 is a closed groove.

[0095] The second track groove wall 212 is positioned opposite to the first track groove wall 211. For example, when the swing track of the slider 31 is located below the virtual rotation axis, the first track groove wall 211 is the lower wall of the track groove 21, and the second track groove wall 212 is the upper wall of the track groove 21.

[0096] In this way, the upper portion of the slider 31 abuts against the second track groove wall 212 , and the shape of the second track groove wall 212 is the same as the motion track of the upper surface of the slider 31 .

[0097] It can be seen that the second track groove wall 212 is adapted to be connected with the first track groove wall 211 to form a closed track groove 21 , which is conducive to improving the constraint effect of the track groove 21 on the slider 31 and ensuring that the slider 31 moves completely according to the set track.

[0098] In some examples, the slider 31 is loosely fitted with the track groove 21, and the wall of the slider 31 that contacts the first track groove wall 211 is arc-shaped. For example, the lower surface of the slider 31 can be an arc-shaped surface, and further, the upper surface of the slider 31 can also be an arc-shaped surface.

[0099] For example, Figure 6 The slider 31 is exemplified as a cylindrical block. Further, in order to facilitate the assembly of the slider 31 into the track groove 21 , a chamfered structure may be provided at the free end of the slider 31 to guide the assembly of the slider 31 into the hole.

[0100] By designing the structure of the slider 31 as described above, the movement of the slider 31 in the track groove 21 is facilitated to be smoother.

[0101] In some implementations, such as the attached Figure 4 and attached Figure 5 As shown, the fixing member 2 also has a rotation groove 22. Figure 6 As shown, the transition piece 3 also has a limit block 33; the limit block 33 is located in the rotation groove 22, and the rotation groove 22 is used to limit the position of the virtual rotation axis, so that the transition piece 3 rotates around the virtual rotation axis and allows the limit block 33 to move up and down.

[0102] The rotation groove 22 is used to limit the position of the virtual axis of rotation, so that the transition piece 3 rotates around the virtual axis of rotation, thereby enhancing the limiting effect on the transition piece 3 and preventing the transition piece 3 from offsetting during the rotation process, thereby being able to control the swing amplitude of the transition piece 3 to reach the target threshold.

[0103] For example, after moving upward to the extreme position, the transition piece 3 will return to its original position downward. The rotation slot 22 cooperates with the limit block 33 to further ensure that the transition piece 3 maintains the desired swing amplitude when the switch is in a static state, so that the compression amount of the spring 52 in the static state of the switch is increased, ensuring that sufficient contact pressure is maintained between the moving contact and the static contact.

[0104] It can be seen that the switch provided in the embodiment of the present invention provides three tracks through the track groove 21, the toggle groove 10 and the rotation groove 22. These three tracks ensure that the transition piece 3 translates upward while rotating, thereby reducing the compression amount of the spring 52 during the toggle process, thereby achieving the purpose of reducing the dialing force.

[0105] The following is an exemplary description of the cooperation between the rotation groove 22 and the limit block 33:

[0106] As attached Figure 5 As shown, the rotation groove 22 is provided on the fixing member 2 at a position corresponding to the limit block 33. The center of the rotation groove 22 coincides with the center of the rotation axis of the virtual rotation axis. The rotation groove 22 limits the position of the virtual rotation axis of the transition member 3 to be fixed, so as to constrain the transition member 3 to move along the swing direction on both sides (for example, Figure 1 on the left and right sides of the image).

[0107] During the swinging process of the transition piece 3, the limit block 33 is constrained by the rotation groove 22 to rotate and move up and down. The rotation groove 22 cooperates with the limit block 33, and the track groove 21 cooperates with the slider 31, so that the movement form of the transition piece 3 is rotation with the virtual axis as the rotation center.

[0108] It can be understood that the position of the virtual rotation axis is fixed, and the position of the actual rotation axis corresponding to the transition piece 3 is constantly changing during the swinging process. In this way, the actual rotation axis of the transition piece 3 is constantly changing to coincide with the virtual rotation axis. The position of the virtual rotation axis is limited by the rotating groove 22, so that the swinging trajectory of the transition piece 3 is easier to be limited, ensuring that the swinging trajectory of the transition piece 3 is consistent with the constraint direction of the trajectory groove 21.

[0109] In some examples, such as the attached Figure 7 As shown, the rotation groove 22 includes two oppositely arranged rotation groove side walls 220, both of which are arc-shaped and bulge toward each other. The wall of the limit block 33 that contacts the rotation groove side walls 220 is arranged in a vertical plane.

[0110] In some examples, such as the attached Figure 7 As shown, the fixing member 2 has a receiving cavity 23, which is used to accommodate the transition member 3. Two support blocks 24 can be symmetrically arranged on the wall of the receiving cavity 23 at the position corresponding to each limit block 33. The cavity between the two support blocks 24 serves as a rotation groove 22, and the above-mentioned rotation groove side walls 220 are provided on the walls of the two support blocks 24 facing each other.

[0111] It can be understood that the center of the horizontal line connecting the two support blocks 24 is the center of the virtual rotation axis.

[0112] For example, when the swing trajectory of the slider 31 is located below the virtual rotation axis, the rotation groove sidewall 220 is disposed on the upper portion of the corresponding inner sidewall of the support block 24 .

[0113] In some examples, a rotation groove 22 is respectively provided at the top of two opposite side walls of the accommodating cavity 23 of the fixing member 2 .

[0114] When the limit block 33 rotates and moves up and down with the transition piece 3, the side wall of the limit block 33 abuts against the side wall 220 of the rotation groove. The arc-shaped side wall 220 of the rotation groove and the planar side wall of the limit block 33 cooperate with each other, so that the rotation groove 22 effectively constrains the swing amplitude of the transition piece 3, and at the same time is beneficial to the smooth movement of the limit block 33.

[0115] In the embodiment of the present invention, the volumes of the rotation groove 22 and the limit block 33 can be designed to be larger to obtain a better restraining effect and to increase the fatigue life of the respective components.

[0116] The following is an exemplary description of the cooperation between the toggle slot 10 and the movable connecting block 32:

[0117] See also Figure 3 The toggle groove 10 accommodates the movable connecting block 32 and uses its sidewall to toggle the movable connecting block 32 to rotate. Therefore, the design of the toggle groove 10 must meet the requirements of toggling the movable connecting block 32 to rotate it and allowing the movable connecting block 32 to move up and down during the rotation process. The upward movement distance of the movable connecting block 32 in the toggle groove 10 is the same as the upward movement distance of the slider 31 in the track groove 21.

[0118] In the embodiment of the present invention, the volumes of the toggle slot 10 and the movable connecting block 32 can be designed to be larger to obtain a better driving effect and to increase the fatigue life of the respective components.

[0119] In some examples, such as the attached Figure 9 As shown, the toggle slot 10 includes two oppositely arranged toggle slot side walls 101, which are arranged in a vertical plane; the movable connecting block 32 has two oppositely arranged arc-shaped side portions 320, which respectively abut against the corresponding toggle slot side walls 101.

[0120] By using the planar structure of the toggle slot side wall 101 to drive the arc-shaped side portion 320 of the movable connection block 32, the movable connection block 32 can be quickly toggled to rotate, and the planar structure of the toggle slot side wall 101 is also conducive to guiding the movable connection block 32 to move up and down therein.

[0121] In some examples, such as the attached Figure 9 As shown, two paddles 11 are symmetrically arranged at the middle position of the panel 1 , the cavity between the two paddles 11 serves as the toggle slot 10 , and the walls of the two paddles 11 facing each other serve as the toggle slot side walls 101 .

[0122] Furthermore, as attached Figure 9 As shown, a hinge block 12 with an axial hole is provided at each side of the panel 1, and a rotating shaft is provided at the corresponding position on the shell assembly 4. The rotating shaft is located in the axial hole of the hinge block 12, thereby realizing the rotation of the panel 1 relative to the shell assembly 4.

[0123] In some examples, such as the attached Figure 1 and attached Figure 2 As shown, the shell assembly 4 includes: a cover 41 and a base 42. The cover 41 is snapped onto the top of the base 42. The two are connected to form a accommodating space. The panel 1 is hinged to the cover 41. The fixing part 2, the transition part 3, the ball assembly 5, the shell assembly 4 and the functional module 6 are located in the accommodating space formed by the cover 41 and the base 42.

[0124] It can be understood that the positions of the track groove 21 , the toggle groove 10 and the rotation groove 22 can be determined according to the positions of the slider 31 , the movable connection block 32 and the limit block 33 on the transition piece 3 .

[0125] In some examples, the slider 31 and the movable connection block 32 are arranged at intervals along the axial direction of the transition piece 3 . For example, one of the sliders 31 and the movable connection block 32 is arranged at the upper end of the transition piece 3 , and the other is arranged at the lower end of the transition piece 3 .

[0126] Since the transition piece 3 moves in a full circle around the virtual axis, the movement trajectory of the slider 31 can be located below the virtual axis, or the movement trajectory of the slider 31 can be located above the virtual axis. Both of the above can achieve the purpose of reducing the switch dialing force. The following are exemplary explanations:

[0127] In some examples, the slider 31 is located below the virtual axis. Figure 8The upward movement amplitude control section 2111 is in an arc-shaped convex shape, and the swing amplitude control section 2112 is in an arc-shaped concave shape. The upward movement amplitude control section 2111 and the swing amplitude control section 2112 are smoothly connected and the upward movement amplitude control section 2111 is located above the swing amplitude control section 2112.

[0128] Further, based on this example, an exemplary structure of the transition piece 3 can be seen in Figure 6 The slider 31 is located at the lower part of the transition piece 3, the movable connecting block 32 is located at the upper part of the transition piece 3, and the limit block 33 is located on the movable connecting block 32 or at the part of the transition piece 3 between its upper and lower ends.

[0129] The transition piece 3 includes a swing arm 30, and an assembly hole for accommodating the ball assembly 5 is provided on the swing arm 30. Figure 6 The example shows a movable connecting block 32 connected to the upper end of the swing arm 30, two limit blocks 33 connected to opposite sides of the movable connecting block 32, and two sliders 31 connected to opposite sides of the lower end of the swing arm 30. The two arc-shaped side portions 320 of the movable connecting block 32 are located on opposite sides along a first direction, and the two limit blocks 33 are located on opposite sides of the movable connecting block 32 along a second direction. The distribution direction of the two limit blocks 33 is the same as the distribution direction of the two sliders 31.

[0130] By arranging the limit block 33 on the movable connecting block 32, the limit block 33 is positioned as high as possible and close to the panel 1. This means that the position of the virtual rotation axis of the transition piece 3 is also as close as possible to the panel 1. This is conducive to amplifying the swing angle of the panel 1, so that the small stroke of the panel 1 is converted into a large stroke of the transition piece 3, thereby reducing the thickness of the switch. The switch provided in the embodiment of the present invention can be designed as an ultra-thin switch. In this way, the switch provided in the embodiment of the present invention has both ultra-thinness and a lighter dialing feel.

[0131] It can be seen that the switch provided by the embodiment of the present invention can effectively reduce the pressing stroke of the panel 1 while ensuring a lighter feel when switching, which is conducive to the lightweight and compact development of the switch, and improves the flatness and aesthetics of the switch when installed on the wall.

[0132] In other examples, the slider 31 is located above the virtual rotation axis. In combination with this example, for the track groove 21, the track groove 21 includes: a first track groove wall 211 abutting against the slider 31, the first track groove wall 211 includes: an upward movement amplitude control section 2111 and two swing amplitude control sections 2112, and the two swing amplitude control sections 2112 are symmetrically arranged on both sides of the upward movement amplitude control section 2111.

[0133] The first track groove wall 211 is located at the upper part of the track groove 21 , and its upward movement amplitude control section 2111 is an arc-shaped protrusion, and the swing amplitude control section 2112 is also an arc-shaped protrusion, and the upward movement amplitude control section 2111 is protruded above the swing amplitude control section 2112 .

[0134] Further, for this example, see Figure 11 As shown in the swinging trajectory, for the transition piece 3, the slider 31 can be located at the upper part of the transition piece 3, the movable connecting block 32 can be located at the lower part of the transition piece 3, and the limit block 33 can be located on the movable connecting block 32 or at the part of the transition piece 3 between its upper and lower ends.

[0135] When the slider 31 is located above the virtual axis, the swinging principle of the transition member 3 is substantially the same as when the slider 31 is located below the virtual axis. The following describes the operation of the switch provided by the embodiment of the present invention in accordance with the case where the slider 31 is located below the virtual axis.

[0136] As attached Figure 6 As shown, the slider 31 is located below the virtual shaft. Specifically, the slider 31 is located at the upper end of the transition piece 3, the movable connecting block 32 is located at the upper end of the transition piece 3, and the limit block 33 is located on the movable connecting block 32. Figure 8 As shown, the upward movement amplitude control section 2111 of the first track groove wall 211 of the track groove 21 is an arc-shaped convex shape, and the swing amplitude control section 2112 is an arc-shaped concave shape. The upward movement amplitude control section 2111 and the swing amplitude control section 2112 are smoothly transitioned and connected, and the upward movement amplitude control section 2111 is located above the swing amplitude control section 2112.

[0137] Combine Figure 10 The swing trajectory shown in FIG. 1 and the movement process of the switch provided by the embodiment of the present invention are as follows:

[0138] Pressing the panel 1 causes it to rotate. The panel 1 utilizes its toggle slot 10 to toggle the movable connecting block 32 on the transition piece 3, causing the transition piece 3 to move. Simultaneously, the transition piece 3 moves within the track slot 21 located on the fixed piece 2 via the slider 31. The track slot 21 constrains the slider 31 of the transition piece 3, while the rotation slot 22 constrains the limit block 33 of the transition piece 3, thereby fixing the motion of the transition piece 3. Ultimately, the slider 31 slides along the track slot 21 and rotates about the virtual axis. Finally, the moving transition piece 3 acts on the seesaw of the functional module 6 via the ball assembly 5, achieving the on / off function of the switch.

[0139] Among them, when the toggle groove 10 drives the transition piece 3 to rotate, the slider 31 is constrained by the track groove 21 on the fixed piece 2, so that the transition piece 3 rotates around the virtual axis defined by the rotation groove 22, and the transition piece 3 moves upward as a whole during the rotation process, which includes: the slider 31 moves upward along the track groove 21, the movable connecting block 32 moves upward along the toggle groove 10, and the limit block 33 moves upward along the rotation groove 22 until the transition piece 3 moves upward to the highest point.

[0140] When the transition piece 3 translates upward to the highest point, the panel 1 and the components inside the switch are still in an unbalanced state. For example, the panel 1 is pressed and rotated to a horizontal arrangement, and then the panel 1 continues to be pressed and rotated, and the rotating transition piece 3 translates downward from the highest point, which includes: the slider 31 moves downward along the track groove 21, the movable connecting block 32 moves downward along the toggle groove 10, and the limit block 33 moves downward along the rotation groove 22 until the switch is dialed. All components in the switch are in a stable equilibrium state, and the compression amount of the spring 52 increases compared to when the transition piece 3 is at the highest point, and stabilizes at the target value to ensure that there is a desired contact pressure between the moving and static contacts.

[0141] The switch provided by the embodiment of the present invention has at least the following advantages:

[0142] First, the dialing force is reduced by changing the dialing form. This is because the main force during the dialing process of the switch is the compression force of the spring 52, and the compression force of the spring 52 is positively correlated with the compression amount of the spring 52 during the dialing process. The embodiment of the present invention reduces the compression amount of the spring 52 during the dialing process, and further reduces the friction force through the force of the spring 52, thereby achieving the purpose of reducing the dialing force.

[0143] Second, the power-carrying performance in the closed state is maintained. This is because the dialing force is reduced by reducing the compression of the spring 52, which is achieved through the relative movement of the transition piece 3 in the upper and lower positions during the dialing process. This does not change the compression of the spring 52 in the closed static state and the swing amplitude of the transition piece 3. The contact pressure of the moving and static contacts in this state can be guaranteed to ensure good power-carrying performance.

[0144] Third, the swinging process of the transition piece 3 is precisely positioned by built-in components, including the aforementioned slider 31, track groove 21, stop block 33, and rotation groove. In related art, the motion trajectory of the transition piece 3 is an arc around the transition piece 3's rotation axis. However, in the embodiment of the present invention, the motion trajectory of the transition piece 3 is the arc of the motion trajectory of the slider 31. The direction of this arc pointing to the virtual rotation axis is the same as the compression direction of the spring 52. This allows the switch dialing angle to be positioned by each built-in component. In addition, the movable connecting block 32 cooperates with the toggle groove 10 on the button. Compared with the dialing with clearance in related art, the positioning of the built-in component can be accurately transmitted to the panel 1.

[0145] Controlling the swinging process of the transition piece 3 by the above-mentioned built-in components has at least the following advantages:

[0146] (1) The product quality of the switch can be precisely controlled. The related art relies on a limit method such as the panel 1 to control the swing angle of each component inside the switch. Due to the limitation of processing accuracy, there are tolerances and gaps in the components, which will lead to problems such as instability in the assembly of internal functional components. The switch provided by the embodiment of the present invention avoids this problem.

[0147] (2) It can reduce the dialing sound. In the related art, the kinetic energy impact generated by dialing can only rely on the collision of components at the limit position, which produces a loud dialing sound. However, the embodiment of the present invention uses internal components to control the swing process of the transition piece 3. The number of components involved in positioning increases, the kinetic energy is dispersed, and the spring 52 can effectively absorb energy after participation, thereby effectively reducing the dialing sound.

[0148] (3) It can precisely control the dialing angle. When designing a small swing angle switch, which has high requirements for the tilting angle, the related art relies on position limits to position the dialing angle, which is prone to gaps due to tolerances, and thus leads to gaps in the relevant transmission components. This requires interference fit when designing the component dimensions, resulting in deformation of the appearance of the switch products without gaps. The embodiment of the present invention uses built-in components to control the dialing angle, which can achieve integrated angle linkage and avoid gaps.

[0149] (4) Improving the service life of the switch. In the embodiment of the present invention, the force arm at the connection position between the toggle slot 10 of the panel 1 and the movable connecting block 32, as well as the connection position between the rotating slot 22 and the limit block 33 are shorter and the contact pressure is greater, which are the easily worn areas of the transmission components. According to the tribological formula, increasing the wearable volume of the wear area can increase the product life. In the embodiment of the present invention, the volume of the movable connecting block 32 and the rotating slot 22 can be designed to be larger to increase the wearable volume, thereby improving the fatigue life of the relevant components and further improving the service life of the switch.

[0150] (5) The switch of the embodiment of the present invention has greater versatility. By changing the movement and constraint forms of various components in the switch, the switch can adapt to various conditions and has strong versatility.
