The switch is an electric device for turning on and off a circuit, and the purpose of turning on or off the circuit is achieved by pressing a button of the switch to rotate the button.

In the switch that correlation technique provided, the direct lock of button is in the top of transition piece, and the lower part and the bullet subassembly of transition piece are connected, and the bullet subassembly acts on the wane on, like this, can drive the transition piece and rotate thereupon when the button is pressed and rotates, and pivoted transition piece and then drive the bullet subassembly and stir the wane for movable contact on the wane contacts or separates with the stationary contact on the terminal subassembly, realizes circuit switch-on or disconnection.

However, in the related art, if the rotation axis of the button is consistent with the rotation axis of the transition piece, if the rocker is moved to the proper position by the elastic component, the rotation stroke of the button needs to be large enough, which increases the depth of the fixing frame and further increases the thickness of the switch.

It can be seen that, on the premise of ensuring that the rocker is pushed to the proper position by the elastic component, it is necessary to reduce the rotation stroke of the button, so that the small-stroke rotation of the button is converted into the large-stroke rotation of the transition piece, which is of great significance to the lightness and thinness of the switch.

The embodiment of the utility model provides a switch, as shown in figure 1 and figure 2, this switch includes: the device comprises a fixed frame 1, a middle frame component 2, a button 3, a pressing piece 4, a switch functional component 5, a transition piece 6 and a support piece 7; wherein, center subassembly 2 encloses the outside of locating mount 1, and casting die 4, switch functional unit 5 all are located mount 1 inside, and the top of transition piece 6 and the upper portion swing joint of casting die 4, the lower part of transition piece 6 runs through casting die 4 and acts on switch functional unit 5. The supporting piece 7 is hinged with the top of the pressing piece 4, the button 3 is connected with the supporting piece 7, and the button 3 is buckled on the top of the middle frame component 2.

With the push button 3, the push button 3 has two pressing sides, one of which always tilts up when the switch is in the off state (conversely, when the switch is in the on state, the pressing side is pressed to droop), and the other of which of the push button 3 tilts down when the switch is in the off state (conversely, when the switch is in the on state, the pressing side correspondingly moves to tilt up). When the switch needs to be switched between the off state and the on state, the push button 3 may be pushed on the push side that is tilted upward.

Since the supporting member 7 is hinged to the top of the pressing member 4, the button 3 is connected to the supporting member 7, so that when the switch needs to be switched from the off state to the on state, the button 3 can be rotated by pressing the pressing side of the button 3, which is tilted upward, and the supporting member 7 rotates relative to the pressing member 4, so that the button 3 rotates together.

In particular, the button 3 is also in abutment with the transition piece 6, so that the transition piece 6 can be driven in rotation by the button 3, and the centre of the rotation trajectory of the transition piece 6 is located above the centre of the rotation trajectory of the button 3, i.e. the axis of rotation of the transition piece 6 is a virtual axis of rotation located above the axis of rotation of the button 3. The button 3 is contacted with the transition piece 6, so that the button 3 can act on the transition piece 6 to rotate the transition piece, and the rotating transition piece 6 directly acts on the switch functional component 5, so that the switch functional component 5 is switched from an off state to an on state, and the switch from the off state to the on state is completed.

The embodiment of the utility model provides a switch, button 3-transition 6 contact in proper order and drive, and this makes the turned angle of button 3 and transition 6 the same to, the pressing force of button 3 directly transmits to transition 6, makes the atress of transition 6 more direct, and the conduction of pressing force is more stable. In particular, by locating the center of the rotation track of the transition piece 6 above the center of the rotation track of the push button 3, the rotation stroke of the transition piece 6 must be greater than that of the push button 3 when the rotation angles of the transition piece 6 and the push button 3 are the same.

It is visible, the embodiment of the utility model provides a switch when reducing button 3's rotation stroke, still can make transition piece 6 obtain great rotation stroke to make the bullet subassembly stir the wane and target in place, and then can realize that button 3's little stroke rotates the switching to transition piece 6's big stroke pivoted. The embodiment of the utility model provides a switch is guaranteeing under the prerequisite that the wane swing targets in place, has effectively reduced the stroke of pressing of button 3, and this is favorable to the frivolousization and the compactification development of switch. In addition, by making the turning stroke of the button 3 designed to be smaller, it is also advantageous to improve the pressing feeling, and to improve the flatness and the beauty when installed on the wall surface.

The structure of the components in the switch is further exemplarily described below:

in some examples, as shown in fig. 3, the button 3 includes: the button comprises a button body 30, a first driving block 31, a second driving block 32 and a connecting block 33, wherein the first driving block 31, the connecting block 33 and the second driving block 32 are sequentially connected with different positions at the bottom of the button body 30, and the first driving block 31 and the second driving block 32 are oppositely arranged, so that the first driving block 31 and the second driving block 32 are positioned at two opposite sides of the button body 30.

The first driving block 31 abuts one end of the top of the transition piece 6 and the second driving block 32 abuts the other end of the top of the transition piece 6. The connecting piece 33 is connected to the support 7 so that a connection is formed between the push button 3 and the support 7.

As can be seen from fig. 4, one of the first and second driving blocks 31 and 32 is close to the tilted-up side of the push button 3, and the other is close to the tilted-down side of the push button 3. By arranging the first and second driving blocks 31 and 32 on the button 3 in opposition, one of the first and second driving blocks 31 and 32 will drive a top end of the transition piece 6 when the button 3 is pressed for rotation, so that the transition piece 6 rotates, so that the pressing force of the button 3 can be transmitted more directly to the transition piece 6, and the transmission of the pressing force is more stable.

In the rotating process of the transition piece 6, two end parts of the top of the transition piece 6, which are abutted against the first driving block 31 and the second driving block 32, are just positioned on the arc where the rotating track of the top of the transition piece 6 is positioned, and finally, the circle center of the rotating track of the transition piece 6 is positioned above the circle center of the rotating track of the button 3.

In the embodiment of the present invention, as shown in fig. 5, the transition piece 6 includes: a transition piece body 60, a first drive block 61 and a second drive block 62; the first and second transmission blocks 61 and 62 are connected to opposite ends of the transition piece body 60, respectively.

The structure of the transition piece 6 is improved relative to the related art, and the improvement point is that a first transmission block 61 and a second transmission block 62 are additionally arranged, wherein the end part of the first transmission block 61 far away from the transition piece body 60 is provided with a first track shaft 610, and the end part of the second transmission block 62 far away from the transition piece body 60 is provided with a second track shaft 620; the top wall of the first trajectory shaft 610 abuts against the first driving block 31, and the top wall of the second trajectory shaft 620 abuts against the second driving block 32, so that the transition piece 6 can be driven to rotate by the button 3.

First orbit axle 610 and second orbit axle 620 are the cylinder to, the axis perpendicular to of cylinder the embodiment of the utility model provides an upper and lower direction. For example, when the switch is switched from the off state to the on state, the first driving block 31 is driven to drive the first trajectory shaft 610 against the first driving block, so that the transition piece 6 rotates in the counterclockwise direction; conversely, when the switch is switched from the on state to the off state, the second driving block 32 is driven to abut against the second trajectory shaft 620, so that the transition piece 6 rotates clockwise.

The first track shaft 610 and the second track shaft 620 are arranged at the two ends of the top of the transition piece body 60 to be matched with the supporting piece 7, so that smoothness of the transition piece 6 when the transition piece is driven to rotate is improved.

Further, as shown in fig. 3, the first driving block 31 and the second driving block 32 have the same structure, and each includes a connection section 311, and a plurality of driving sections 312 connected to the connection section 311; the plurality of driving segments 312 are arranged at intervals along a length direction of the connection segment 311, wherein the length direction of the connection segment 311 is the same as the length direction of the first trajectory axis 610 and the second trajectory axis 620.

A first driving block 31 and a second driving block 32 are disposed on the button body 30 at positions corresponding to both ends of the top of the transition piece 6, and illustratively, as shown in fig. 3, the connecting section 311 has a flat plate shape, the top end of the connecting section 311 is vertically connected to a corresponding position on the bottom wall of the button body 30, the driving sections 312 have a flat plate shape, the top ends of the plurality of driving sections 312 are vertically connected to a corresponding position on the bottom wall of the button body 30, and the side end of each driving section is vertically connected to a surface of the connecting section 311 facing the support member 7.

The plurality of driving segments 312 are uniformly arranged at intervals along the length direction of the connecting segment 311, so that the plurality of driving segments 312 can offset different positions on the first track shaft 610 or the second track shaft 620, and the driving effect is improved. Meanwhile, the above design of the plurality of driving sections 312 also functions as a reinforcing rib, which is beneficial to improving the strength of the button 3.

For example, the first trajectory axis 610 may have two ends of the first trajectory axis 610 along the length direction thereof respectively abutted against one driving segment 312, and other portions of the first trajectory axis 610 may be abutted against a plurality of, for example, two, three, four or more driving segments 312.

Further, as shown in fig. 3, the bottom end of the driving section 312 has an arc-shaped groove 3120, the arc of the arc-shaped groove 3120 is the same as the arc of the first trajectory shaft 610 and the second trajectory shaft 620 (the arc length direction of the arc-shaped groove 3120 is the same as the rotation direction of the first trajectory shaft 610 or the second trajectory shaft 620), and the driving section 312 is fit against the first trajectory shaft 610 or the second trajectory shaft 620 through the arc-shaped groove 3120.

The arc-shaped slot 3120 is used for accommodating and guiding the rotation of the corresponding track shaft, which makes the rotation driving process of the button 3 to the transition piece 6 more efficient and smooth.

For the transmission block arranged with the track shaft, in some examples, the first transmission block 61 and the second transmission block 62 have the same structure, and the length of the first transmission block 61 and the second transmission block 62 gradually increases from the end of the transmission block connected with the transition piece body 60 to the end of the transmission block arranged with the track shaft; the length directions of the first transmission block 61 and the second transmission block 62 are the same as the length directions of the first track shaft 610 and the second track shaft 620.

That is, first transmission piece 61 and second transmission piece 62 all are similar to trapezoidal shape, and wherein, the end connection of the minimum length of first transmission piece 61 and second transmission piece 62 and transition piece body 60, first orbit axle 610 and second orbit axle 620 have been arranged respectively to the maximum length one end of first transmission piece 61 and second transmission piece 62, and this makes the structure of first transmission piece 61 and second transmission piece 62 more stable, and does benefit to the stability and the reliability of the rotation process of orbit axle.

In order to further optimize the above effect, the ends of the first and second transmission blocks 61 and 62 having the maximum length have a certain width in a direction perpendicular to the length direction of the above-mentioned transmission blocks.

As shown in fig. 5, the length of the first trace shaft 610 is greater than the maximum length of the first transmission block 61, and the length of the second trace shaft 620 is greater than the maximum length of the second transmission block 62, so that both ends of the trace shaft protrude from both ends of the corresponding transmission blocks, respectively, so as to enable both ends of the trace shaft to be inserted into corresponding positions on the pressing member 4, so that the trace shaft can rotate relative to the pressing member 4.

In some implementations, as shown in fig. 6, the compression element 4 includes: the pressing member comprises a pressing member body 40, a through hole 41 and four track grooves 42, wherein the through hole 41 is positioned in the middle of the pressing member body 40, two track grooves 42 are positioned at two ends of a first side of the pressing member body 40, and the other two track grooves 42 are positioned at two ends of a second side, opposite to the first side, of the pressing member body 40. The lower portion of the transition piece body 60 passes through the hole 41 to facilitate the action on the switch function 5, and the other portion of the transition piece body 60 is located above the pressing piece 4.

As shown in fig. 7, two ends of the first trace shaft 610 are respectively located in the two trace grooves 42 at corresponding positions, and two ends of the second trace shaft 620 are respectively located in the two trace grooves 42 at corresponding positions; the trajectory groove 42 is configured to guide the movement of the first trajectory shaft 610 and the second trajectory shaft 620, and to restrain the first trajectory shaft 610 and the second trajectory shaft 620 to the pressing member 4.

In the embodiment of the present invention, it is desirable that, while the transition piece 6 rotates, the first track shaft 610 and the second track shaft 620 are located on the arc where the rotation track of the top of the transition piece 6 is located, so that the design of the track groove 42 at least conforms to the rotation track of the first track shaft 610 and the second track shaft 620, thereby effectively creating a virtual rotation axis for the transition piece 6.

In addition, at the same time, since the transition piece body 60 penetrates through the through hole 41 on the pressing piece 4, the transition piece 6 also has a tendency to be separated from the pressing piece 4 in the up-down direction while rotating, and therefore, the track groove 42 is also designed to be capable of limiting the first track shaft 610 and the second track shaft 620 in the up-down direction at the rotation limit position.

It can be seen that through the design of the track groove 42, it is ensured that the first track shaft 610 and the second track shaft 620 on the transition piece 6 not only can stably and controllably move along the track groove 42, but also can be limited by the track groove 42, so that the transition piece 6 cannot be separated from the pressing piece 4 all the time in the moving process, which is beneficial to ensuring that the rotating process of the transition piece 6 is not only stable and controllable, but also is rapid and efficient, and the triggering hand feeling is improved.

For example, as shown in fig. 6, the track groove 42 includes a first groove wall 421 and a second groove wall 422, and the first groove wall 421 and the second groove wall 422 are connected end to form a closed track groove 42. The first groove wall 421 is configured to abut against a lower portion of the first trajectory axis 610 or the second trajectory axis 620, and the second groove wall 422 is configured to abut against an upper portion of the first trajectory axis 610 or the second trajectory axis 620.

The first groove wall 421 and the second groove wall 422 can not only guide the rotation of the track shaft, but also limit the track shaft.

By way of example with further reference to fig. 7, when the button 3 is pressed to rotate the transition piece 6 counterclockwise, both ends of the first trajectory shaft 610 rotate along the first groove walls 421 of the corresponding trajectory grooves 42, and at the same time, both ends of the second trajectory shaft 620 rotate against the second groove walls 422 of the corresponding trajectory grooves 42, so that the transition piece 6 can smoothly rotate counterclockwise to a desired limit position (see the upper half of fig. 7). When the button 3 is pressed to rotate the transition piece 6 clockwise, both ends of the second trajectory shaft 620 rotate along the first groove walls 421 of the corresponding trajectory grooves 42, and at the same time, both ends of the first trajectory shaft 610 rotate to abut against the second groove walls 422 of the corresponding trajectory grooves 42, so that the transition piece 6 can smoothly rotate clockwise to a desired limit position (see the lower half in fig. 7).

Each of the trace grooves 42 may be formed by, as shown in fig. 6, the pressing member body 40 including a pressing plate portion 401, two first side surrounding portions 402, two second side surrounding portions 403, and four arc-shaped ribs 404; the two first side surrounding parts 402 are respectively connected with the opposite first side and second side of the pressing plate part 401; two second skirt portions 403 are connected to the third and fourth opposing sides of the platen portion 401, respectively. A gap is formed between any adjacent first side surrounding part 402 and second side surrounding part 403, the arc-shaped rib 404 is positioned at the gap, two open ends of the arc-shaped rib 404 are connected with one end of the corresponding first side surrounding part 402, and the back of the arc-shaped rib 404 is connected with one end of the corresponding second side surrounding part 403; the inner wall of the arc rib 404 forms a second groove wall 422 and the end wall of the first side skirt portion 402 forms a first groove wall 421. That is, the track groove 42 is formed by fitting the arc rib 404 and the first skirt portion 402.

In some examples, the compression plate portion 401, the two first side surrounding portions 402, the two second side surrounding portions 403, and the four arc ribs 404 are integrally formed to obtain the compression element body 40, in which case, an end portion of the second side surrounding portion 403 may be punched, so that the end portion of the second side surrounding portion 403 is punched to form the arc ribs 404, and the track groove 42 is formed between the first side surrounding portion 402 and the second side surrounding portion 403.
