In order to make the technical solutions and advantages of the present invention clearer, the following will make a detailed description of embodiments of the present invention with reference to the accompanying drawings.

The switch is common electric current on-off device, and at present, the switch is usually designed for wane formula or pendulum piece formula, and in these two types of switches, the transition piece all passes through compression spring and connects drive structure to the realization dials wanes or pendulum piece.

However, the dialing performance of the known rocker switch or swing switch is limited, for example, the rocker switch is easy to generate an arc phenomenon when dialing, the swing switch is easy to generate a virtual position when dialing, and the assembling process of the rocker switch or swing switch is slightly complicated.

In order to solve the technical problem existing in the related art, the embodiment of the present invention provides a switch, as shown in fig. 1 to fig. 3, the switch including: panel 1, base 2, transition component 3, movable contact component 4 and stationary contact component 5.

As shown in fig. 3, the movable contact assembly 4 includes: the spring plate 41, the wiring terminal 42 connected and fixed in the middle of the spring plate 41, and the movable contact 43 connected and fixed in the end of the spring plate 41; the movable contact assembly 4 and the stationary contact assembly 5 are both located inside the base 2, and the movable contact 43 corresponds to the stationary contact 50 on the stationary contact assembly 5.

The panel 1 can be pressed and rotated relative to the base 2, and the transition component 3 is connected to the panel 1 and hinged to the base 2; the transition component 3 comprises a driving rib 300, and the transition component 3 can be pressed by the panel 1 to rotate so as to deform the corresponding position of the elastic sheet 41 through the driving rib 300, so that the movable contact 43 is contacted with or separated from the fixed contact 50.

As can be seen from fig. 3 and 4, two opposite sides of the base 2 are respectively provided with the first positioning structures 201, two opposite sides of the transition assembly 3 are respectively provided with the second positioning structures 301, at least one of the first positioning structures 201 and the second positioning structures 301 has elasticity, and one of the first positioning structures 201 and the second positioning structures 301 has a first positioning position 601, a driving position 602, and a second positioning position 603, which are sequentially distributed from top to bottom.

When the switch is in the on-state or the off-state, the second positioning structure 301 and the corresponding first positioning structure 201 on one side of the transition member 3 are positioned with respect to each other by the first positioning location 601, and the second positioning structure 301 and the corresponding first positioning structure 201 on the other side of the transition member 3 are positioned with respect to each other by the second positioning location 603.

When the switch is switched between the on state and the off state, the second positioning structures 301 on both sides of the transition assembly 3 can be pressed against the corresponding first positioning structures 201 by the driving positions 602.

The embodiment of the utility model provides a switch has made following improvement for traditional rocker switch and pendulum piece switch at least:

firstly, a movable contact assembly 4 with an improved structure is used, wherein the terminal 42 is fixed at the middle part of the elastic sheet 41, the movable contact 43 is fixed at the end part of the elastic sheet 41, and the part of the elastic sheet 41 between the terminal 42 and the movable contact 43 is pressed by the driving rib 300 to be elastically deformed, so that the position change of the movable contact 43 is realized, and the movable contact 43 is contacted with or separated from the fixed contact 50.

With the wane switch the transition piece must drive the wane swing in order to realize the position change of movable contact to and with the position change that the transition piece must drive the balance swing in order to realize the movable contact in the balance swing switch compare, the embodiment of the utility model provides a this operation mode of movable contact subassembly 4, because terminal linkage segment 411 fixed connection is in shell fragment 41, in movable contact 43 position change in-process, binding post 42 and movable contact 43 electric connection all the time, can not have the arc problem that draws that the wane switch arouses because of the wane is beated, also can not have the balance swing switch to dial the virtual bit problem because of balance swing arousing, and then make the utility model provides a dial the performance and dial the feeling of beating of switch and all can promote. Moreover, this also facilitates the design of the transition member 3 and the spring 41 with a small longitudinal dimension, which facilitates the design of the switch as ultra-thin.

Secondly, the structure of elastic mechanism and its arrangement in the switch have been improved, and two first location structures 201 symmetrical arrangement are in the both sides of base 2, and two second location structures 301 symmetrical arrangement are in the relative both sides of transition subassembly 3, and first location structure 201 and second location structure 301 can become the location each other when the switch is in the steady state to and, can extrude each other when the switch is in the unstability state. At least one of the second positioning structure 301 and the first positioning structure 201 is made resilient to cooperate to form a resilient mechanism, without additionally arranging a resilient member such as a spring.

It will be appreciated that the two resilient means formed by the cooperation of the second locating formation 301 and the first locating formation 201 are located on either side of the transition member 3, one of which is correspondingly located below the upturned side of the panel 1 and the other of which is correspondingly located below the downturned side of the panel 1, both of which are arranged horizontally in the switch.

When the switch is in a stable on-state or off-state, one of the second positioning structures 301 on both sides of the transition member 3 is positioned with respect to the corresponding first positioning structure 201 by the first positioning location 601, and the other is positioned with respect to the corresponding first positioning structure 201 by the second positioning location 603, so that each movable part of the switch is in a stable state.

For example, fig. 3 illustrates that when the normally closed switch is in the on state, the second positioning structure 301 on the left is positioned at the first positioning position 601 of the first positioning structure 201 on the left, and the second positioning structure 301 on the right is positioned at the second positioning position 603 of the first positioning structure 201 on the right.

Fig. 8 illustrates that when the normally closed switch is in the open state, the second positioning structure 301 on the left is positioned at the second positioning position 603 of the first positioning structure 201 on the left, and the second positioning structure 301 on the right is positioned at the first positioning position 601 of the first positioning structure 201 on the right.

When the panel 1 is pressed to drive the transition assembly 3 to rotate, during the rotation of the transition assembly 3, the second positioning structure 301 at the side part thereof is displaced relative to the first positioning structure 201, and the two are abutted by the driving position 602 (see fig. 7, which illustrates that the second positioning structure 301 with elasticity is deformed by being pressed by the driving position 602), and the two are pressed against each other to make the elastic mechanism elastically deformed to generate a resilience force, under the action of which each movable component in the switch is in a destabilizing state. Therefore, as long as the panel 1 is continuously pressed with force, the second positioning structure 301 will rapidly enter the corresponding positioning position of the first positioning structure 201, so as to promote the transition component 3 to rapidly complete dialing, thereby achieving the effect of instant dialing.

All utilize in rocker switch and pendulum piece switch vertically to realize the level or vertically to dial in the spring at switch middle part and compare, the embodiment of the utility model provides an arrange elastic mechanism at the both sides level of switch and realize dialling transition subassembly 3 fast, it is more direct that the mode of should dialling, the virtual position of dialling can not appear, can effectively promote to dial and feel.

In particular, the elastic means formed by the cooperation of the first positioning structure 201 and the second positioning structure 301 are respectively integrated in the base 2 and the transition assembly 3, and no additional elastic member such as a spring is arranged, which not only facilitates the simplification of the structure of the switch, but also facilitates the improvement of the assembly efficiency of the switch.

The first positioning structure 201 and the second positioning structure 301 are positioned relative to each other in a manner including, but not limited to: the accommodation positioning between the groove and the projection, the magnetic connection positioning between the surfaces and the like.

For example, referring to fig. 3 and 4, the first positioning position 601 and the second positioning position 603 are both concave, and the driving position 602 is convex, and the three cooperate to form a wavy or wave-like track groove.

One of the first positioning structure 201 and the second positioning structure 301 has a first positioning position 601, a driving position 602, and a second positioning position 603, and the other can be accommodated in the first positioning position 601 and the second positioning position 603 for positioning and pressed against the driving position 602.

Fig. 3 and 4 illustrate that the first positioning structure 201 has a first positioning position 601, a driving position 602 and a second positioning position 603, and that the second positioning structure 301 is provided in the shape of a projection to be able to be received in the first positioning position 601 and the second positioning position 603 for positioning and pressed against the driving position 602.

Of course, it is also feasible that the first positioning location 601, the driving location 602 and the second positioning location 603 are arranged on the second positioning structure 301, and that the first positioning structure 201 is arranged in a convex shape.

As can be seen from fig. 3 and 4, when the switch is in the on state or the off state, one of the second positioning structures 301 on both sides of the transition assembly 3 is located at the first positioning position 601 (see fig. 4 and 6) of the corresponding first positioning structure 201, and the other is located at the second positioning position 603 (see fig. 4 and 5) of the corresponding first positioning structure 201.

When the switch is switched from the on-state to the off-state, the two second positioning structures 301 on both sides of the transition assembly 3 can be pressed against the respective drive positions 602 of the first positioning structures 201 (see fig. 7).

Referring to fig. 4, the base 2 has fixing blocks 202 at both sides thereof, respectively, and the first positioning structure 201 is formed on a wall of the fixing block 202 facing the second positioning structure 301. The first positioning structure 201 has the first positioning position 601, the driving position 602, and the second positioning position 603. Accordingly, the second positioning structure 301 is provided in a convex shape to be fittingly received in the first positioning position 601 and the second positioning position 603 and to be capable of abutting the driving position 602.

By providing the fixing block 202 on the base 2, the first positioning structure 201 having a certain track is formed thereon, and the fixing block 202 has a certain strength, which can improve the structural stability of the first positioning structure 201 and prevent the first positioning position 601, the driving position 602, and the second positioning position 603 from being deformed in shape.

For example, the fixing block 202 is a rectangular block with a simple structure and is convenient for molding, and the first positioning structure 201 is formed on a rectangular wall of the second positioning structure 301.

In some implementations, referring to fig. 4, 5, and 6, the second positioning structure 301 is an elastic block and the fixed block 202 is a rigid block.

Thus, it is very advantageous to improve the structural stability of the first positioning structure 201, and when the second positioning structure 301 abuts against the driving position 602 of the first positioning structure 201 of the fixed block 202, the fixed block 202 is not deformed, and the second positioning structure 301 is elastically deformed, so that the transition component 3, the panel 1, and the like are in a destabilizing state.

The second positioning structure 301 may be made elastic by modifying its structure and/or material, may be made elastic in various ways, such as by modifying its structure to have a deformable cavity, or may be made elastic, for example.

Referring to fig. 5 and 6, the second positioning structure 301 has a first deformation cavity 3010 to make the second positioning structure 301 elastic.

The first deformation cavity 3010 is designed to at least enable a wall of the second positioning structure 301 facing the first positioning structure 201 to deform when an external force is applied, the first deformation cavity 3010 may be formed in the second positioning structure 301 in various ways, for example, in the form of a blind hole or a through hole, and the axial direction of the first deformation cavity 3010 may be along the horizontal direction or the vertical direction, as long as it is ensured that the wall of the second positioning structure 301 facing the first positioning structure 201 is a closed wall.

Fig. 9 illustrates that the first deformation cavity 3010 is a through hole penetrating through both ends of the second positioning structure 301, and the axial direction of the first deformation cavity 3010 is along the horizontal direction, the second positioning structure 301 with this structure type has the advantages of easy molding preparation, good deformation effect, and the like.

In some examples, as shown in fig. 10, a reinforcing block 203 is further disposed on the base 2, and the reinforcing block 203 is connected between a wall of the fixing block 202 facing away from the second positioning structure 301 and a side wall of the base 2, for example, the reinforcing block 203 may be a rectangular rod, a triangular rod, a trapezoidal block, or the like, and by providing the reinforcing block 203, the arrangement strength and the structural stability of the fixing block 202 in the base 2 can be further improved.

In some examples, the fixing block 202 and the optional reinforcing block 203 are integrally formed on the base 2.

In some implementations, referring to fig. 12 and 13, the second positioning structure 301 is a rigid block and the fixed block 202 is an elastic block. Thus, when the second positioning structure 301 abuts against the driving position 602 of the first positioning structure 201 of the fixed block 202, the fixed block 202 is elastically deformed, and the second positioning structure 301 is not deformed, so that the transition assembly 3, the panel 1, and the like are in a destabilized state.

The elasticity may be imparted by modifying the structure and/or material of the fixing block 202, for example, by modifying the structure to have a deformable cavity, or by using an elastic material.

Referring to fig. 5 and 6, the fixing block 202 has a second deformation chamber 2020 to make the fixing block 202 elastic.

The second deformation cavity 2020 is designed such that the wall of the fixing block 202 facing the second positioning structure 301 (i.e. the wall of the first positioning structure 201) is not deformed, but the wall can perform a compression movement in a direction away from the second positioning structure 301 and a reset movement in a direction close to the second positioning structure 301, so that the wall of the first positioning structure 201 can have a sufficient strength to prevent the first positioning position 601, the driving position 602 and the second positioning position 603 from deforming in shape while ensuring the elasticity of the fixing block 202.

The second deforming cavity 2020 may be formed in the fixing block 202 in various ways, for example, in the form of a blind hole or a through hole, and the axial direction of the second deforming cavity 2020 may be in the horizontal direction or in the vertical direction, as long as it is ensured that the wall where the first positioning structure 201 is located is a closed wall.

Fig. 12 illustrates that the second deformation cavity 2020 is a through hole penetrating through both ends of the fixed block 202, and the axial direction of the second deformation cavity 2020 is along the vertical direction, the fixed block 202 with this structure type is easy to mold and prepare on the base 2, and the deformation effect is good.

As shown in fig. 12, the fixing block 202 includes a first rigid wall 2021, a first flexible wall 2023, a second rigid wall 2022 and a second flexible wall 2024 connected end to end in sequence, the four walls enclose to form a second deformation cavity 2020, and the first positioning structure 201 is formed on a surface of the second rigid wall 2022 facing the second positioning structure 301.

The first rigid wall 2021 and the second rigid wall 2022 are rigid walls, which do not deform when subjected to an external force, and the first flexible wall 2023 and the second flexible wall 2024 are flexible walls, which deform when subjected to an external force, so that the position of the wall of the first positioning structure 201 can be changed.

For the second positioning structure 301 and the first positioning structure 201 mentioned in the above implementation manners, in some implementation manners, one of the first positioning structure 201 and the second positioning structure 301 has a first positioning position 601, a driving position 602, and a second positioning position 603, both the first positioning position 601 and the second positioning position 603 are arc-shaped grooves, and the driving position 602 is an arc-shaped protrusion; one of the first positioning structure 201 and the second positioning structure 301 is a protrusion having a circular arc-shaped wall.

Fig. 9 shows that the first positioning structure 201 has a first positioning location 601 in the form of a circular arc-shaped groove, a driving location 602 in the form of a circular arc-shaped projection and a second positioning location 603 in the form of a circular arc-shaped groove, and that the second positioning structure 301 is a projection with a circular arc-shaped wall. As can be further seen from fig. 10, the first positioning position 601 and the second positioning position 603 are in the shape of an inward concave arc, and the driving position 602 is in the shape of an outward convex arc.

As a typical example, the second positioning structure 301 is a cylindrical block, and the first positioning position 601 and the second positioning position 603 are both arc-shaped grooves adapted to the arc of the second positioning structure 301.

By the arrangement, the second positioning structure 301 moves along the first positioning structure 201 more smoothly and rapidly, which is more beneficial to improving the dialing hand feeling of the switch.

For the movable contact assembly 4 involved in the switch provided by the embodiment of the present invention, referring to fig. 13, it exemplifies the structure of the elastic sheet 41, as shown in fig. 13, the elastic sheet 41 includes: a terminal connection section 411, two spring sections 412, one or two contact connection sections 413. First ends of the two elastic segments 412 are respectively connected to two opposite ends of the terminal connection segment 411, so that the two elastic segments 412 are located at two sides of the terminal connection segment 411.

When the number of the contact connecting segments 413 is one, the second end of one of the elastic segments 412 may be connected to the contact connecting segment 413 to adapt to a single-control switch; and, when the number of the contact connecting sections 413 is two, the second ends of the two elastic sections 412 may be connected to one contact connecting section 413, respectively, to accommodate the dual-control switch.

The connection terminal 42 is fixedly connected through the terminal connection section 411 located at the middle of the elastic piece 41, and the movable contact 43 is fixedly connected through the contact connection sections 413 located at both ends of the elastic piece 41, so that the elastic section 412 located between the connection terminal 42 and the movable contact 43 is pressed by the driving rib 300, the elastic section 412 can be elastically deformed, and then the position of the movable contact 43 is driven to move, so that the movable contact 43 and the stationary contact 50 are contacted or separated.

In some examples, a high-elasticity metal sheet is used, and the spring plate 41 of an integrated structure is formed by performing operations such as stamping, bending, cutting and the like on the high-elasticity metal sheet. For example, the metal sheet may be a copper sheet, which enables the spring plate 41 to have excellent elasticity, electrical conductivity and thermal conductivity.

In some examples, the elastic section 412 and the terminal connection section 411 have an included angle therebetween in a range of 120 ° to 180 °, for example, this includes but is not limited to: 120 °, 130 °, 140 °, 150 °, 170 °, 180 °, etc.

When the included angle between the elastic section 412 and the terminal connection section 411 is less than 180 ° and greater than or equal to 120 °, the elastic section 412 is obliquely disposed above the terminal connection section 411. In this way, the elastic section 412 is more easily driven to elastically deform, and can obtain a larger elastic potential energy when deforming.

In other examples, referring to fig. 14, the contact connecting section 413 includes: a connecting guide segment 4131 and a connecting contact segment 4132, the guide segment 4131 being obliquely arranged with respect to the resilient segment 412 such that the connecting contact segment 4132 is located above or below the resilient segment 412.

The guide segment 4131 may be disposed obliquely downward or obliquely upward with respect to the resilient segment 412, and by obliquely disposing the guide segment 4131, the connection contact segment 4132 is located above or below the resilient segment 412.

For example, for a normally closed switch, the movable contact 43 is located below the elastic section 412, and for a normally open switch, the movable contact 43 is located above the elastic section 412, and the above orientation of the movable contact 43 is arranged.

In some examples, with the connecting contact section 4132 arranged in the horizontal direction, and thus the movable contact 43 also arranged horizontally accordingly, when the stationary contact 50 in the switch is also arranged horizontally, the movable contact 43 and the stationary contact 50 can be brought into complete surface-to-surface contact, the contact area is increased, and a larger contact pressure is obtained.

The elastic segments 412 may be elongated with uniform width or elongated with non-uniform width. The length direction of the spring 41 refers to the distribution direction from the contact connecting section 413 to the terminal connecting section 411; the width direction of the spring plate 41 refers to a direction perpendicular to the length direction thereof and extending in a horizontal plane.

In some examples, the resilient segments 412 are not uniform in width, as shown in fig. 9, the resilient segments 412 include: and a first resilient segment 4121 and a second resilient segment 4122 connected, wherein an end of the first resilient segment 4121 remote from the second resilient segment 4122 is connected to the terminal connection segment 411, and an end of the second resilient segment 4122 remote from the first resilient segment 4121 is connected to the contact connection segment 413. From the terminal connection section 411 to the second resilient section 4122, the width of the first resilient section 4121 is gradually reduced, and the minimum width of the first resilient section 4121 is equal to the width of the second resilient section 4122.

By making the width of the first resilient section 4121 longer at a position close to the terminal connection section 411 and gradually smaller in a direction away from the terminal connection section 411, it is possible to improve fatigue resistance between the resilient section 412 and the terminal connection section 411. This is because, the position of the terminal connection section 411 is fixed, the elastic section 412 is frequently deformed and displaced with respect to the terminal connection section 411, and the unrecoverable hard deformation is prevented from occurring by increasing the width at that position to accommodate the frequent displacement of the elastic section 412. By making the width of the second resilient segment 4122 equal to the minimum width of the first resilient segment 4121, this facilitates to increase the resilient deformability of the second resilient segment 4122 to have a higher amount of deformation.

For the connection terminal 42, it is connected to the terminal connection section 411 of the elastic sheet 41, and the connection mode between the two includes but is not limited to: welding, joint, riveting etc., wherein, modes such as joint, riveting are all dismantled easily, do benefit to the assembly process who simplifies binding post 42 and are convenient for maintain or change. For example, the connection terminal 42 is clamped to the terminal connection section 411.
