Description

Technical Field

[0001] This invention relates to the field of electrical switch technology, and in particular to a transmission structure, switch, and socket. Background Technology

[0002] A switch is a type of electrical switch used to control the opening and closing of a circuit. Traditional switches consist of a button, a lever, and a terminal assembly. Turning the button drives the lever to swing, thus opening or closing the circuit in the terminal assembly.

[0003] However, in traditional technology, the button needs to be rotated at a large angle for the lever to swing a sufficient range of space to allow different terminals in the terminal assembly to be connected to the circuit, which is not convenient for achieving small-angle rotation of the button in the switch. Summary of the Invention

[0004] Therefore, it is necessary to provide a transmission structure, switch, and socket to address the problem of how to make a switch on or off by rotating a button only a small angle.

[0005] A transmission structure is provided for transmitting the rotation of a button to a terminal assembly to achieve circuit on / off control. The transmission structure includes a front transition member and a rear transition member. The front transition member is connected to the button. Both the front and rear transition members are rotatably connected to a bracket. The end of the front transition member away from the button is connected to the rear transition member to pry the rear transition member to rotate. The end of the rear transition member away from the front transition member is connected to the terminal assembly. When the rear transition member rotates, it drives the terminal assembly to operate to achieve circuit on / off control.

[0006] Along the extending direction of the rear transition member, the distance from the contact point between the rear transition member and the front transition member to the rotation axis of the rear transition member is less than the distance from the contact point between the rear transition member and the terminal assembly to the rotation axis of the rear transition member.

[0007] In one embodiment, the front transition member has a first cavity, one end of the rear transition member extends into the first cavity and abuts against the cavity wall of the first cavity. When the front transition member rotates, the cavity wall of the first cavity pushes the rear transition member to rotate. There is a gap between the upper part of the rear transition member and the cavity wall of the first cavity.

[0008] In one embodiment, the rear transition member includes a rod and a limiting body connected to the outer peripheral wall of the rod. The rod is inserted into the first cavity and abuts against the cavity wall of the first cavity. The limiting body extends along the axial direction of the rod towards the front transition member to form a barrier. The barrier surrounds the front transition member. At two extreme positions during the rotation of the front transition member, the front transition member abuts against the limiting body and / or the barrier.

[0009] In one embodiment, the transmission structure further includes a first elastic element located within the first cavity. The first elastic element elastically abuts against the bottom wall of the first cavity and the rear transition member. The first cavity extends along the front axis, and the rear transition member extends along the rear axis. When the front axis and the rear axis coincide, the first elastic element has a maximum compression.

[0010] In one embodiment, the transmission structure further includes a second elastic member. The rear transition member has a second cavity with an opening facing the terminal assembly. The second elastic member is disposed in the second cavity and elastically abuts against the bottom wall of the second cavity and the terminal assembly. The second cavity extends along the rear axis. When the front axis is parallel to the rear axis, the second elastic member has a maximum compression.

[0011] In one embodiment, the front transition member includes an open position, a middle position, and a closed position, wherein when in the open position, the front axis and the rear axis intersect at a first intersection point;

[0012] When in the closed position, the front axis and the rear axis intersect at the second intersection point;

[0013] When in the middle position, the front axis coincides with the rear axis, and the first intersection point and the second intersection point are located on both sides of the front axis and the rear axis.

[0014] In one embodiment, the front transition member includes a first pivot for rotatable connection with the bracket, the first pivot being located on the front transition member closer to the button relative to the rear transition member.

[0015] A switch, comprising:

[0016] support;

[0017] A button and a terminal assembly, wherein the button is rotatably connected to the bracket, and the terminal assembly is disposed within the bracket;

[0018] As described in any of the above embodiments, the transmission structure is connected between the button and the terminal assembly to transmit the movement of the button to the terminal assembly.

[0019] In one embodiment, the terminal assembly includes a rocker arm, a first terminal, and a second terminal. The first terminal and the second terminal are disposed on the bracket. One side of the rocker arm is connected to a rear transition member, and the other side of the rocker arm is rotatably disposed on the bracket. When the rear transition member rotates, it drives the rocker arm to rotate, and the rocker arm rotates to contact the first terminal and the second terminal respectively, thereby realizing the circuit switching; and / or

[0020] The rear transition piece has a first slot on the side near the rocker arm, and the rocker arm extends into the first slot and abuts against the wall of the first slot.

[0021] A socket comprising a switch as described in the above embodiments.

[0022] In the aforementioned transmission structure, the rotational motion of the button is transmitted to the terminal assembly via the front and rear transition members. The rear transition member is rotatably connected to the bracket, and both ends of the rear transition member are connected to the front transition member and the terminal assembly, respectively. Thus, the rear transition member forms a simple lever. Since the distance from the contact point between the rear and front transition members to the rotation axis of the rear transition member is less than the distance from the contact point between the rear and terminal assembly to the rotation axis of the rear transition member, the connection point between the front and rear transition members can drive a larger displacement at the connection point between the rear transition member and the terminal assembly with a relatively small displacement. In other words, the rear transition member amplifies the displacement of the front transition member away from the button. With this configuration, for the same distance the connection point between the rear transition member and the terminal assembly moves, the button can rotate at a relatively small angle.

[0038] See Figure 1 and Figure 2 Figure 1 shows a schematic diagram of the switch from one side of an embodiment of the present invention. Figure 2 for Figure 1 An exploded view of the switch is shown. An embodiment of the present invention provides a switch 10 including a button 200, a terminal assembly 300, a bracket 400, and a transmission structure 100. The button 200 is rotatably connected to the bracket 400, and the terminal is disposed within the bracket 400. The transmission structure 100 is connected between the button 200 and the terminal assembly 300 to transmit the rotational movement of the button 200 on the bracket 400 to the terminal assembly 300. The button 200 transmits its movement to the terminal assembly 300 through the transmission structure 100, enabling small-angle control of the circuit opening and closing of the terminal assembly 300.

[0039] Please see Figures 2 to 4In one embodiment, the transmission structure 100 includes a front transition member 110 and a rear transition member 120. The front transition member 110 is used to connect with the button 200, and both the front transition member 110 and the rear transition member 120 are rotatably connected to the bracket 400. The end of the front transition member 110 away from the button 200 is connected to the rear transition member 120 to pry the rear transition member 120 to rotate, and the end of the rear transition member 120 away from the front transition member 110 is used to connect with the terminal assembly 300. That is, both ends of the front transition member 110 are connected to the button 200 and the rear transition member 120 respectively; both ends of the rear transition member 120 are connected to the front transition member 110 and the terminal assembly 300 respectively, and the front transition member 110 and the rear transition member 120 are sequentially connected end-to-end between the button 200 and the terminal assembly 300.

[0040] When the rear transition piece 120 rotates, it drives the terminal assembly 300 to operate to realize the circuit switching. That is, the front transition piece 110 and the rear transition piece 120 transmit the movement of the button 200 to the terminal assembly 300 so that the terminal assembly 300 operates accordingly to realize the circuit switching control.

[0041] Combination Figure 4 Along the extending direction of the rear transition member 120, the distance from the contact point between the rear transition member 120 and the front transition member 110 to the rotation axis of the rear transition member 120 is less than the distance from the contact point between the rear transition member 120 and the terminal assembly 300 to the rotation axis of the rear transition member 120.

[0042] In the aforementioned transmission structure 100, the rotational motion of the button 200 is transmitted to the terminal assembly 300 via the front transition member 110 and the rear transition member 120. The rear transition member 120 is rotatably connected to the bracket 400, and both ends of the rear transition member 120 are connected to the front transition member 110 and the terminal assembly 300, respectively. Thus, the rear transition member 120 forms a simple lever. The front transition member 110 applies a force to the rear transition member 120 through contact to drive the rear transition member 120 to rotate; similarly, the rear transition member 120 applies a force to the terminal assembly 300 through contact to drive the terminal assembly 300 to move. Therefore, the distance from the contact point between the rear transition member 120 and the front transition member 110 to the rotation axis of the rear transition member 120 is set to be less than the distance from the contact point between the rear transition member 120 and the terminal assembly 300 to the rotation axis of the rear transition member 120. This allows the contact point between the front transition member 110 and the rear transition member 120 to drive a larger displacement between the contact point between the rear transition member 120 and the terminal assembly 300 with a relatively small displacement in space. In other words, the rear transition member 120 can amplify the displacement of the end of the front transition member 110 away from the button 200. With this configuration, the button 200 can rotate at a relatively small angle, driving the terminal assembly 300 to have the same or greater range of motion.

[0043] It is understandable that for a lever structure with different lengths on both sides of the fulcrum, the displacement of the free end of the longer lever is greater than the displacement of the free end of the shorter lever when it rotates through a certain angle.

[0044] Specifically, in combination Figure 4 Taking the extension direction of the rear transition member 120 as M, the contact point between the front transition member 110 and the rear transition member 120 as point E, the contact point between the rear transition member 120 and the terminal assembly 300 as point H, and the rotation axis of the rear transition member 120 as O as an example, the explanation will be based on this. The distance from the contact point between the rear transition member 120 and the front transition member 110 to the rotation axis of the rear transition member 120 is L1; the distance from the contact point between the rear transition member 120 and the terminal assembly 300 to the rotation axis of the rear transition member 120 is L2. Figure 4 As shown, L1 is smaller than L2, so button 200 can rotate at a relatively small angle, and drive terminal assembly 300 has the same or greater range of motion.

[0045] Please see Figure 2 In one embodiment, the front transition member 110 includes a first rotating shaft 112, which is rotatably connected to the bracket 400. Specifically, the first rotating shaft 112 can be rotatably connected to the first connecting portion 411. The first rotating shaft 112 is located on the front transition member 110 closer to the button 200 than the rear transition member 120. Similarly to the above embodiment, setting the position of the first rotating shaft 112 closer to the button 200 allows the button 200 to rotate through a small angle, resulting in a relatively large displacement at the connection between the front transition member 110 and the rear transition member 120. The bracket 400 is provided with the first connecting portion 411, and the first rotating shaft 112 is rotatably connected to the first connecting portion 411 to allow the entire bracket 400 to rotate relative to it via the first connecting portion 411.

[0046] Please continue reading. Figure 2 In one embodiment, the rear transition member 120 includes a second rotating shaft 125, which is rotatably connected to the bracket 400. The bracket 400 includes a second connecting portion 421, and the second rotating shaft 125 is rotatably connected to the second connecting portion 421 to allow overall rotation relative to the bracket 400 via the second connecting portion 421. Figure 4 It is understandable that the rotation axis of the rear transition piece 120 is the central axis of the second rotating shaft 125.

[0047] Please see Figure 3 and Figure 5In one embodiment, a first cavity 111 is formed within the front transition member 110, and one end of the rear transition member 120 extends into the first cavity 111 and abuts against the cavity wall of the first cavity 111. When the front transition member 110 rotates, the cavity wall of the first cavity 111 pushes the rear transition member 120 to rotate. With this configuration, when the front transition member 110 rotates under the drive of the button 200, the cavity wall of the first cavity 111 can push the rear transition member 120 to rotate, thereby realizing the transmission of motion from the front transition member 110 to the rear transition member 120.

[0048] There is a gap between the upper part of the rear transition member 120 and the cavity wall of the first cavity 111 to avoid the rear transition member 120 and the cavity wall of the first cavity 111 being too tightly fitted, which would prevent the rear transition member 120 and the front transition member 110 from moving relative to each other. Specifically, the rear transition member 120 can be inserted into the first cavity 111 with a gap and abut against the cavity wall of the first cavity 111 when the front transition member 110 rotates.

[0049] Please see Figure 5 In one embodiment, the rear transition member 120 includes a rod 122 and a limiting body 123 connected to the outer peripheral wall of the rod 122. The rod 122 is inserted into the first cavity 111 and abuts against the cavity wall of the first cavity 111. The limiting body 123 extends axially along the rod 122 toward the front transition member 110 to form a barrier 124. The barrier 124 surrounds the front transition member 110, and at two extreme positions during the rotation of the front transition member 110, the front transition member 110 abuts against the limiting body 123 and / or the barrier 124. This arrangement can limit the rotation angle of the front transition member 110 to prevent the rod 122 from disengaging from the first cavity 111 due to excessive rotation angle.

[0050] In some embodiments, the limiting body 123 and the enclosure 124 may not be provided. By reasonably adjusting the size of the cavity wall of the first cavity 111 and the size of the insertion rod 122 extending into the first cavity 111, the outer surface of the insertion rod 122 can be used to limit the rotation of the front transition member 110, thereby preventing the insertion rod 122 from coming out of the first cavity 111.

[0051] Of course, in some embodiments, the rotation angle of the button 200 can also be limited to restrict the rotation of the front transition member 110.

[0052] Please see Figure 2In one embodiment, the bracket 400 includes a front seat 410 and a rear seat 420 connected to the front seat 410. The button 200 and the front transition member 110 are both rotatably connected to the front seat 410, and the button 200 and the front transition member 110 are coaxially rotatably connected, thus enabling more synchronized rotation between the button 200 and the front transition member 110. The rear transition member 120 is rotatably connected to the rear seat 420, which is hollow, and the terminal assembly 300 is disposed within the rear seat 420. The aforementioned coaxial rotatable connection means that the rotation axis of the button 200 coincides with the rotation axis of the front transition member 110.

[0053] Please see Figure 3 , Figure 6 and Figure 7 In one embodiment, button 200 includes an open position, a middle position, and a closed position. When button 200 is in the open position, terminal assembly 300 is open; when button 200 is in the closed position, terminal assembly 300 is closed. Figure 3 Button 200 is in the open position. Figure 6 Button 200 is in the middle position as shown. Figure 7 The button 200 shown is in the off position.

[0054] Accordingly, the front transition member 110 includes an open position, a middle position, and a closed position corresponding to the button 200. When the front transition member 110 is in the open position, the terminal assembly 300 is open; when the front transition member 110 is in the closed position, the terminal assembly 300 is closed. Figure 3 The front transition piece 110 shown is in the open position. Figure 6 The front transition piece 110 shown is in the middle position. Figure 7 The front transition piece 110 shown is in the closed position.

[0055] Please see Figure 2 and combined Figures 3 to 7 In one embodiment, the transmission structure 100 includes a first elastic member 130 located within a first cavity 111. The first elastic member 130 elastically abuts against the bottom wall of the first cavity 111 and the rear transition member 120, meaning the first elastic member 130 is in a compressed state within the first cavity 111. The first cavity 111 extends along a front axis, and the rear transition member 120 extends along a rear axis. In other words, the distance from the point of contact between the rear transition member 120 and the front transition member 110 to the rotation axis of the rear transition member 120 is less than the distance from the point of contact between the rear transition member 120 and the terminal assembly 300 to the rotation axis of the rear transition member 120.

[0056] When the front and rear axes coincide, the first elastic element 130 has its maximum compression. For structures with elastic properties, the greater the deformation, the greater the elastic restoring force; that is, the greater the contact force exerted by the first elastic element 130 on the front transition element 110 and the rear transition element 120. (See front axis diagram.) Figures 3 to 7 Center mark K; see rear axis. Figures 3 to 7 The standard number is M.

[0057] It is understandable that the compression of the first elastic element 130 is related to the size of the rear transition element 120 extending into the first cavity 111. The larger the size of the rear transition element 120 extending into the first cavity 111, the greater the compression of the first elastic element 130; conversely, the smaller the size, the smaller the compression. During the rotation of the front transition element 110 and the rear transition element 120, the first elastic element 130 has the maximum compression when the front axis coincides with the rear axis. At this time, the compression of the first elastic element 130 decreases regardless of which side the front transition element 110 rotates to. In other words, when the front axis coincides with the rear axis, the elastic restoring force of the first elastic element 130 can assist in pushing the front transition element 110 to rotate regardless of which side the front transition element 110 rotates to.

[0058] Conversely, the first elastic element 130 has the maximum compression when the front axis and the rear axis coincide. That is to say, during the rotation of the front transition element 110, no matter which side of the front transition element 110 rotates in the direction that makes the front axis and the rear axis coincide, the elastic force of the first elastic element 130 will act as a resistance to the rotation of the front transition element 110.

[0059] Please continue reading. Figure 3 , Figure 6 and Figure 7 In one embodiment, the function of the first elastic member 130 is explained with reference to the specific position of the front transition member 110. In the open position, the front axis and the rear axis intersect at a first intersection point. In the closed position, the front axis and the rear axis intersect at a second intersection point. In the intermediate position, the front axis and the rear axis coincide, and the first intersection point and the second intersection point are located on opposite sides of the front and rear axes. The axis where the front and rear axes coincide is defined as the reference axis. As the front transition member 110 rotates from the open position to the closed position, the first intersection point gradually approaches the reference axis. At this time, the compression of the first elastic member 130 gradually increases, and its elastic force also gradually increases, acting as a resistance to the rotation of the front transition member 110. Until the front transition member 110 reaches the intermediate position, the first intersection point falls onto the reference axis, and the compression of the first elastic member 130 reaches its maximum. As the front transition member 110 continues to rotate, when the first intersection point crosses the reference axis and becomes the second intersection point, the compression of the first elastic member 130 gradually decreases, and its elastic force acts as a driving force to rotate the front transition member 110. The same principle applies when rotating from the closed position to the open position, so I won't go into details.

[0060] This design serves two purposes: firstly, it prevents the button 200 from rotating due to accidental touches; secondly, it facilitates the quick switching of the button 200 and the front transition piece 110 from the middle position to the open or closed position.

[0061] Please continue reading. Figures 2 to 7 In one embodiment, the transmission structure 100 further includes a second elastic member 140. A second cavity 121 with an opening facing the terminal assembly 300 is provided on the rear transition member 120, and the second elastic member 140 is disposed within the second cavity 121. The second elastic member 140 elastically abuts against the bottom wall of the second cavity 121 and the terminal assembly 300. The second cavity 121 extends along the rear axis, and the second elastic member 140 has its maximum compression when the front axis is parallel to the rear axis. It is understood that the second elastic member 140, abutting against the bottom wall of the second cavity 121 and the terminal assembly 300, has a similar function to the first elastic member 130, to prevent the button 200, which rotates at a small angle, from rotating due to accidental touch, and to facilitate the rapid switching of the button 200 and the front transition member 110 from the intermediate position to the open or closed position.

[0062] Specifically, the first elastic element 130 and the second elastic element 140 may be compression springs or other similar elastic bodies.

[0063] Please see Figure 8 In one embodiment, the first terminal 320 and the second terminal 330 can be respectively disposed on the top wall and bottom wall of the rear seat 420. When the rear transition member 120 drives the rocker 310 to rotate, the rocker 310 can contact and electrically connect with the first terminal 320 and the second terminal 330 respectively to achieve a circuit or a circuit break.

[0064] Please see Figure 8 In one embodiment, the rear transition member 120 has a first slot 122a on the side near the rocker arm 310. The rocker arm 310 extends into the first slot 122a and abuts against the wall of the first slot 122a to prevent the rocker arm 310 from separating from the rear transition member 120. One end of the second elastic member 140 abuts against the bottom wall of the second cavity 121, and the other end of the second elastic member 140 may abut against the rocker arm 310.

[0065] In one embodiment, a second slot (not shown in the figure, the same below) is provided on the inner wall of the rear seat 420, and one side of the rocker arm 310 extends into the second slot and abuts against the slot wall. The slot wall restricts the position of the rocker arm 310 away from the rear transition member 120, thus, in conjunction with the first slot 122a and the second elastic member 140, the position of the rocker arm 310 can be stabilized. Of course, the rocker arm 310 can also be connected to the bracket 400 in other ways.

[0066] Please see Figure 2and Figure 8 In one embodiment, the terminal assembly 300 includes a rocker arm 310, a first terminal 320, and a second terminal 330. The first terminal 320 and the second terminal 330 are disposed on a bracket 400, specifically on a rear seat 420. One side of the rocker arm 310 is connected to a rear transition member 120, and the other side of the rocker arm 310 is rotatably disposed on the bracket 400. When the rear transition member 120 rotates, it drives the rocker arm 310 to rotate until it contacts the first terminal 320 and the second terminal 330 respectively, thereby realizing the circuit connection and disconnection.

[0067] Please see Figure 8 In one embodiment, the side of the rocker 310 near the rear transition member 120 is used to contact the first terminal 320 and the second terminal 330. In this way, the space within the bracket 400 can be fully utilized, and the lateral dimension of the rocker 310 can be relatively reduced.

[0068] Please see Figure 8 In one embodiment, the rocker arm 310 includes a contact 312 and a latching portion 311. The latching portion 311 is used to engage with a first latching groove 122a. The contact 312 is used to contact a first terminal 320 and a second terminal 330. The distance between the contact 312 and the wall of the first latching groove 122a is greater than the distance between the latching portion 311 and the wall of the first latching groove 122a. Similar to the lever structure described above, in this case, since the distance between the contact 312 and the wall of the first latching groove 122a is greater than the distance between the latching portion 311 and the wall of the first latching groove 122a, the rocker arm 310 can amplify the displacement of the latching portion 311 to a certain extent, so that the contact 312 has a larger displacement relative to the latching portion 311, in order to meet the requirement of contacting the first terminal 320 or the second terminal 330.

[0069] One embodiment of the present invention also provides a socket. The socket includes the switch 10 described in various embodiments, which can realize the opening and closing of the circuit with a small angle control, so that the socket includes a socket that is open or closed. It should be noted that the socket described in this embodiment includes sockets that are directly installed on fixed structures such as walls, and also includes power strips that can be connected by cables and are movable.

[0070] In one embodiment, a socket may include one or more switches 10. When a socket includes one switch 10, all sockets can be controlled to be open or closed by the switch 10. When a socket includes multiple switches 10, each switch 10 can be configured to correspond one-to-one with a socket, so as to independently control the opening and closing of any one or more sockets.

[0071] Of course, in other embodiments, the switch 10 is not limited to use in a socket; the switch 10 can be used in any device or equipment that has the requirement of circuit opening and closing control.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
