All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

Wherein, the orientation of the surface cover of the switch is used as an 'up' or a 'top', and the orientation of the base of the switch is used as a 'down' or a 'bottom'.

With the reset switch provided by the related art, the driving mechanism thereof transmits driving forces from the face cover based on the end portions of the two driving blocks, respectively, which easily causes uneven force application, thereby failing in a frequently used state and affecting the hand feeling.

Aiming at the technical problems existing in the related art, the embodiment of the invention provides a switch, as shown in the accompanying drawings 1-3, which comprises: the face cover 1, the middle frame assembly 2, the base assembly 3, the switch module 4 and the transmission module, wherein the transmission module comprises a driving mechanism 5. The surface cover 1, the middle frame assembly 2 and the base assembly 3 are sequentially connected to form a containing space in a matching way, and the surface cover 1 can perform pressing motion relative to the middle frame assembly 2. The switch module 4 and the transmission module are both located in the above-mentioned accommodation space, and the transmission module is located between the face cover 1 and the switch module 4.

With further reference to fig. 4, the driving mechanism 5 includes a first driving block 51 and a second driving block 52 which are symmetrically arranged, a first end of the first driving block 51 is hinged to a first end of the second driving block 52, and a first end of at least one of the first driving block 51 and the second driving block 52 has a driving portion 501.

The switch is configured such that the first driving block 51 and the second driving block 52 can be driven to move in conjunction by pressing the face cover 1, and further the switch module 4 is directly or indirectly triggered by the driving part 501, and the driving mechanism 5 and the face cover 1 are configured to be reset together after the face cover 1 is canceled.

The switch according to the embodiment of the invention adopts the driving mechanism 5 with improved structural arrangement, the first driving block 51 and the second driving block 52 in the driving mechanism 5 are connected in a linkage manner through a hinged connection, the driving part 501 is arranged at the hinged end of the first driving block and the second driving block, and the driving part 501 transmits the driving force from the face cover 1 to the switch module 4 to trigger the switch, so that the switch is turned on or turned off. Compared with the prior art, the driving mechanism is based on the fact that the driving force from the face cover is transmitted by the end portions of the two driving blocks which are arranged at intervals, and the driving mechanism enables the first driving block 51 and the second driving block 52 to be arranged in a linkage mode. The force applied by the driving mechanism 5 is more balanced, and the force applied by the driving mechanism 5 is more balanced, so that the operation reliability and the hand feeling of the switch are improved.

The driving mechanism 5 according to the embodiment of the present invention is applicable not only to mechanical switches but also to electronic switches. Fig. 1-15 only illustrate the relevant arrangement of the mechanical switch, for which reference is made to the structural arrangement of the drive mechanism 5 in the electronic switch, the embodiment of the invention not being illustrated in the drawings.

For mechanical switches, in some examples, the drive mechanism 5 indirectly triggers the switch module 4 via its drive 501, for example, a reset mechanism 6 may be further arranged in the switch, which reset mechanism 6 is not only capable of transmitting the drive force of the drive 501 to the switch module 4 as a transmission mechanism, but also serves to reset the drive mechanism 5 and the cover 1. The movement of the cover 1 in the mechanical switch may be a rotation.

For electronic switches, in some examples, the drive mechanism 5 directly activates the switch module 4 through its drive 501. In the electronic switch, the switch module 4 adopts an electronic switch, and the electronic switch has elasticity, and one example is that the reset of the face cover 1 and the driving mechanism 5 is promoted by virtue of the elasticity of the electronic switch. Another example is to further provide an elastic reset structure in the switch, for example, a first elastic reset structure is provided for the cover 1, and the first elastic reset structure is used for resetting the cover 1 and further driving the driving mechanism 5 to be reset together. And/or a second elastic reset structure is arranged for the driving mechanism 5, and the first elastic reset structure is used for resetting the driving mechanism 5 so as to drive the face cover 1 to be reset together. The movement of the cover 1 in the electronic switch may be translational in the pressing direction.

The following takes a mechanical switch as an example, and the arrangement of each component is described with reference to the related drawings.

Referring to fig. 1-3, the transmission module further includes a reset mechanism 6, the cover 1, the driving mechanism 5, the reset mechanism 6, and the switch module 4 are sequentially arranged along a direction perpendicular to the cover 1, and the driving portion 501 abuts against the reset mechanism 6. Wherein, the driving mechanism 5 and the reset mechanism 6 are movably arranged in the accommodating space of the switch. The switch is configured such that the first driving block 51 and the second driving block 52 can be driven to move in a linkage manner by pressing the surface cover 1, and then the driving part 501 drives the reset mechanism 6 to move to the state that the switch module 4 can be toggled, and after the surface cover 1 is cancelled, the reset mechanism 6 resets and drives the driving mechanism 5 to reset together with the surface cover 1.

In some examples, the driving portion 501 abuts against a middle region of an end of the reset mechanism 6 facing the face cover 1, and the other end of the reset mechanism 6 facing away from the face cover 1 is used to toggle the switch module 4. Wherein the term "central region" referred to herein refers to a non-edge region of the reset mechanism 6, which is not limited to the region where the center line of the corresponding end of the reset mechanism 6 is located, but may also include other side regions located at a distance on both sides of the center line thereof.

In the related art, the force application position of the driving mechanism in the active state to the reset mechanism is at the edge of the reset mechanism, so that the reset mechanism is unbalanced in stress, is easy to fail in the frequent use state, and affects the hand feeling. The embodiment of the invention enables the driving part 501 to be abutted against the middle area of one end of the reset mechanism 6, and aims to balance the force applied by the driving part 501 to the reset mechanism 6, so that the problem that one side is applied with larger force and the other side is applied with smaller force is avoided, and the technical problem in the related art is solved.

According to the switch provided by the embodiment of the invention, the driving mechanism 5 and the reset mechanism 6 are matched, the pressing surface cover 1 drives the first driving block 51 and the second driving block 52 to move in a linkage manner, and the reset mechanism 6 is driven by the driving part 501 to move until the switch module 4 can be toggled, so that the switch is turned on or off. After the pressing of the cover 1 is canceled, the reset mechanism 6 resets and drives the driving mechanism 5 to reset together with the cover 1, which enables the switch to be designed as a flat switch, thereby reducing the thickness thereof and improving the aesthetic feeling. By providing the driving part 501 at the first end of the first driving block 51 and/or the second driving block 52, the driving part 501 is used to apply force to the end of the reset mechanism 6, which makes the stress of the reset mechanism 6 more balanced, thereby improving the operation reliability and the hand feeling of the switch. Through making the first end of first drive piece 51 and the first end of second drive piece 52 articulated mutually, both can coordinated motion under the pressing drive of panel, this does benefit to and can realize effectual pressing drive in a plurality of positions of panel homoenergetic, promotes the use convenience of switch, promotes user experience.

As for the cover 1, it may also be called a key or a button, and in the embodiment of the present invention, the cover 1 plays a role of a button+a panel, and on one hand, the cover 1 can be pressed to rotate so as to switch the switch between an on state and an off state. On the other hand, the face cover 1 is used to give the switch a surface appearance, giving the switch an aesthetic appearance.

In the embodiment of the present invention, the cover 1 may be designed to be in a flat state, i.e., there is no one-sided tilting.

For the base assembly 3, which is used to provide the accommodating cavity and further accommodate other components such as the switch module 4, as shown in fig. 2-3, for example, the base assembly 3 at least includes a base 32, further, the base assembly 3 may further include a pressing plate 31, for example, fig. 3 illustrates that the base assembly 3 includes both the base 32 and the pressing plate 31, the pressing plate 31 is connected to the base 32 and covers the top of the accommodating cavity of the base 32, and the pressing plate 31 is used to support other components such as the switch module 4 so as to enable them to be stably assembled.

As for the switch module 4, which provides an electrical switching function as a functional module of a switch, for example, as shown in fig. 2 to 3, there is illustrated a switch module 4 adapted for a rocker switch, which includes a transition piece 41, a pin assembly 42, a rocker piece 43, an incoming terminal assembly 44 and an outgoing terminal assembly 45, and the assembly between these components may refer to a rocker switch known at present, and will not be described herein. Wherein the switch module 4 is toggled by the reset mechanism 6 through its transition piece 41.

For the driving mechanism 5, in the embodiment of the present invention, the driving mechanism 5 includes a first driving block 51 and a second driving block 52 which are symmetrically arranged, and the first ends of the first driving block 51 and the second driving block 52 may be directly hinged, or may be indirectly hinged through other structural members.

One example is by providing mating hinge structures at the first end of the first drive block 51 and the first end of the second drive block 52, respectively, to achieve direct articulation of the two. Another example is to provide a movable joint between the first end of the first driving block 51 and the first end of the second driving block 52, and the movable joint is hinged to the first end and the second end respectively, so as to realize indirect hinging of the first driving block and the second driving block. For example, the movable joint may be a shaft, and holes may be provided at the first end of the first driving block 51 and the first end of the second driving block 52, respectively, and the shaft may be hinged to the holes of the first driving block and the second driving block, respectively.

The first driving block 51 and the second driving block 52 are directly hinged, and the structure is simple, the space occupation rate is low, and the like. The mating relationship between the first drive block 51 and the second drive block 52 is further described below by way of example in connection with the direct articulation of the two.

As shown in fig. 4 to 6, the driving portion 501 is provided at a first end of one of the first driving block 51 and the second driving block 52, and the driving portion 501 has a shaft hole 5011. The first end of the other of the first driving block 51 and the second driving block 52 is provided with a first rotation shaft portion 502, and the first rotation shaft portion 502 is hinged to the driving portion 501 through a shaft hole 5011.

By arranging the driving part 501 in one of the first driving block 51 and the second driving block 52 and arranging the first rotating shaft part 502 in the other one of the first driving block 51 and the second driving block 52, the shaft hole 5011 is arranged in the driving part 501 to be hinged with the first rotating shaft part 502, so that the driving part 501 bears the functions of a hinging structure and a driving structure at the same time, the functions are diversified, the internal arrangement of the switch is simplified, and the light and thin design of the switch is facilitated.

For example, the number of driving parts 501 may be one or more, and the driving parts 501 are located at the middle position of the first end of the second driving block 52. For example, fig. 5 illustrates that one shaft hole portion 507, a driving portion 501, and another shaft hole portion 507 are sequentially arranged at intervals along the first end of the second driving block 52. The shaft hole 507 may have the same configuration as the driving unit 501, and the driving unit 501 may act on the reset mechanism 6, so that the shaft hole 507 does not contact the reset mechanism 6, but functions to connect the shaft hole 5011 to the first rotation shaft 502.

The number of the first rotating shafts 502 and the positions thereof may be adaptively designed according to the arrangement of the driving portions 501 and the shaft hole portions 507, for example, fig. 6 illustrates that the first end of the first driving block 51 is provided in two discontinuous portions, one rotating shaft is provided on each side of each portion, that is, four rotating shafts in total, and each portion of the first end of the first driving block 51 correspondingly extends into a gap cavity between the adjacent driving portion 501 and the shaft hole portion 507 and is respectively connected with the corresponding shaft hole 5011 through two rotating shafts.

In some examples, in order to make the driving of the reset mechanism 6 by the driving portion 501 smoother and more labor-saving, thereby improving the feel, the surface of the driving portion 501 in contact with the reset mechanism 6 may be provided in a circular arc shape, for example, referring to fig. 5, and the driving portion 501 may be provided in a cylindrical shape.

In some examples, to optimize the above effect and to increase the driving force of the driving portion 501 on the reset mechanism 6, a protruding feature may also be arranged on the driving portion 501, with which the driving portion 501 acts on the reset mechanism 6.

In the embodiment of the present invention, the first driving block 51 and the second driving block 52 are symmetrically arranged with respect to the center line of the cover 1, wherein the center line of the cover 1 refers to the center line between the first side and the second side of the cover 1, and the center of the center line is the center point of the switch, and the distribution directions of the first side and the second side of the cover 1 are the same as the distribution directions of the first driving block 51 and the second driving block 52.

In some examples, as shown in fig. 2 and 3, the middle frame assembly 2 includes a panel frame 21, and further referring to fig. 7, a first positioning structure 211 and a second positioning structure 212 are symmetrically arranged at both sides of the panel frame 21.

As can be seen in fig. 3, the second end of the first driving block 51 is movably overlapped with the first side portion of the panel frame 21 and is positioned by the first positioning structure 211, such that the second end of the first driving block 51 translates along a direction parallel to the panel cover 1 while rotating. The second end of the second driving block 52 is movably overlapped with the second side portion of the panel frame 21 and is positioned by the second positioning structure 212, so that the second end of the second driving block 52 translates in a direction parallel to the face cover 1 while rotating.

Illustratively, the second end of the first driving block 51 and the second end of the second driving block 52 may be provided in a shaft shape, and the second end of the first driving block 51 and the second end of the second driving block 52 may be referred to as the second shaft portion 503, so that the rotation process thereof is smoother.

The positioning manner of the first positioning structure 211 between the second ends of the first driving blocks 51 may be achieved by a groove-block positioning structure, that is, one of the first positioning structure 211 and the second ends of the first driving blocks 51 may be provided with a positioning groove, and the other one is provided with a positioning block, which extends into the positioning groove and achieves positioning based on the groove wall of the positioning groove.

For example, fig. 3 illustrates that two convex-shaped first positioning structures 211 are arranged at one side of the panel frame 21, and a positioning groove is provided in each first positioning structure 211, and two sides of the second end of the first driving block 51 are respectively provided as positioning blocks.

It will be appreciated that the two sides of the second end of the first driving block 51 are also provided with avoidance grooves at the same time, so as to avoid the outer wall of the convex-shaped first positioning structure 211.

The positioning manner between the second positioning structure 212 and the second end of the second driving block 52 may refer to the positioning manner between the first positioning structure 211 and the second end of the first driving block 51, which is not described herein.

In the embodiment of the present invention, since the first driving block 51 and the second driving block 52 are hinged, the two driving blocks can be linked, on the basis of which, the second end of the first driving block 51 translates along the direction parallel to the face cover 1 while rotating, and the second end of the second driving block 52 translates along the direction parallel to the face cover 1 while rotating. In this way, the interlocking movement of the first driving block 51 and the second driving block 52 can be ensured.

For the linked movement of the first driving block 51 and the second driving block 52, referring to fig. 4, when the second ends of the first driving block 51 and the second driving block 52, i.e., the second rotating shaft portion 503, move in the horizontal direction parallel to the face cover 1 while rotating, the first ends of the first driving block 51 and the second driving block 52 can be made to move in the vertical direction perpendicular to the face cover 1, i.e., move upward or downward, in synchronization, thereby driving the driving portion 501 to move up and down. Alternatively, when the first ends of the first and second driving blocks 51 and 52 are moved in the vertical direction perpendicular to the face cover 1, the second ends of the first and second driving blocks 51 and 52, that is, the second rotation shaft portions 503 can be made to move in the horizontal direction parallel to the face cover 1 while rotating.

Fig. 4 illustrates the respective movement states of the drive mechanism 5 in the pressed state and the reset state of the face cover 1. When the face cover 1 is pressed downwards, the first ends of the first driving block 51 and the second driving block 52 drive the driving part 501 to translate downwards while rotating, and further drive the reset mechanism 6, and at the same time, the second ends of the first driving block 51 and the second driving block 52 translate towards the horizontal direction away from the driving part 501 while rotating. When the cover 1 is reset upwards, the first ends of the first driving block 51 and the second driving block 52 drive the driving part 501 to translate upwards while rotating, and at the same time, the second ends of the first driving block 51 and the second driving block 52 translate towards the horizontal direction close to the driving part 501 while rotating.

It can be seen that through the above arrangement of the first driving block 51 and the second driving block 52, linkage of the two can be realized, so that no matter which position of the pressing surface cover 1 is used, effective driving of the driving mechanism 5 can be realized, the function of controllable switch at any position of the panel is realized, usability of the switch is remarkably improved, and user experience is improved.

In some implementations, the first positioning structure 211 and the second positioning structure 212 are further configured to enable the central axis of the driving part 501 to always coincide with the central axis of the face cover 1; and/or, the middle area of the panel frame 21 is provided with a third positioning structure 213, and the third positioning structure 213 positions the first end of the first driving block 51 and the first end of the second driving block 52, so that the central axis of the driving part 501 always coincides with the central axis of the face cover 1.

By the above arrangement, the center axis of the driving part 501 always coincides with the center axis of the cover 1, which can ensure not only effective linkage between the first driving block 51 and the second driving block 52, but also that the point of application of force to the reset mechanism 6 by the driving part 501 of the driving mechanism 5 is always in the center area of the reset mechanism 6, ensuring the force balance of the reset mechanism 6.

It can be appreciated that, when the cover 1 is in the natural state, the central axis of the driving portion 501, the central axis of the cover 1, and the central axis of the reset mechanism 6 coincide.

In order to realize that the central axis of the driving part 501 always coincides with the central axis of the surface cover 1, the second ends of the moving first driving block 51 and second driving block 52 can be limited in the horizontal direction by using the groove walls of the positioning grooves corresponding to the first positioning structure 211 and the second positioning structure 212 respectively, so that the second ends of the first driving block 51 and the second driving block 52 can be synchronously stopped at the limit position of horizontal movement during movement, and the central axis of the driving part 501 always coincides with the central axis of the surface cover 1.

As mentioned above, the two sides of the second ends of the first driving block 51 and the second driving block 52 are also provided with the avoidance grooves simultaneously to avoid the outer walls of the first positioning structure 211 and the second positioning structure 212 in the form of convex blocks.

It is not to be excluded that the groove wall of the avoidance groove may be used to stop the outer wall of the first positioning structure 211 or the second positioning structure 212, so that the second end of the first driving block 51 and the second end of the second driving block 52 are synchronously stopped at the limit position of horizontal movement during movement, and it is ensured that the central axis of the driving part 501 always coincides with the central axis of the face cover 1.

As for the third positioning structures 213, referring to fig. 7, two third positioning structures 213 may be symmetrically arranged at a middle region of the panel frame 21, and the third positioning structures 213 may include a support plate and a stopper groove opened on the support plate. Correspondingly, the side portion of the first end of at least one of the first driving block 51 and the second driving block 52 is further provided with a positioning shaft 506, for example, the positioning shaft 506 may be connected to the outer side of the shaft hole 507 facing away from the driving portion 501, so that the positioning shaft 506 is further accommodated in the positioning groove of the third positioning structure 213, and thus the central axis of the driving portion 501 always coincides with the central axis of the face cover 1.

It will be appreciated that the stop slot of the third positioning structure 213, the positioning shaft 506, and the central axis of the driving part 501 coincide.

The following describes the working principle of the switch according to the embodiment of the present invention, in which the panel is controllable at any position, with reference to fig. 8 to 10. The side of the cover 1 corresponding to the first driving block 51 is defined as a first side, and the side of the cover 1 corresponding to the second driving block 52 is defined as a second side. Wherein, the face cover 1 can be rotatably connected with corresponding buckling positions on the panel frame 21 of the middle frame assembly 2 through the buckling buckles 12 on the face cover 1, so as to realize the rotation of the face cover 1 relative to the middle frame assembly 2.

For example, as shown in fig. 8, the second side of the face cover 1 is pressed, and the face cover 1 is pressed and rotated around the fastening point of the first side as a rotation axis. The second side of the cover 1 is pressed to rotate downward, and thereby drives the second driving block 52 to rotate about its second end (shaft-like) as a rotation shaft, and drives the driving part 501 to move downward while rotating. Since the second positioning structure 212 and/or the third positioning structure 213 define that the central axis of the driving portion 501 always coincides with the central axis of the cover 1, the second end of the second driving block 52 translates away from the central axis of the cover 1 while rotating (see fig. 9). Since the second driving block 52 is hinged with the first driving block 51, the first driving block 51 is interlocked with the second driving block 52 while the second driving block 52 is moved. The driving part 501 moves downward and drives the reset mechanism 6, so that the reset mechanism 6 toggles the switch module 4 to switch on or off, for example, to switch the switch to an on state (see fig. 10).

After the switch is turned on, the cover 1 is not pressed any more, and then the reset mechanism 6 resets and drives the driving part 501 to reset upwards, so that the driving mechanism 5 resets to the initial state, and the driving mechanism 5 in the reset motion drives the cover 1 to reset to the natural state, that is, the flat state.

When it is necessary to switch the switch from the on state to the off state, the cover 1 is pressed again, for example, the second side of the cover 1 is pressed again, and the reset mechanism 6 toggles the switch module 4 again to switch the switch to the off state according to the same principle as described above.

Based on the similar operation principle, the first side of the surface cover 1 is pressed, the movement of the first driving block 51 refers to the movement of the second driving block 52, and finally the first driving block and the second driving block are linked to drive the reset mechanism 6 to toggle the switch module 4, so as to realize the switching of the switch state.

If the middle position of the surface cover 1 is pressed, the surface cover 1 moves downwards in a horizontal state, so that the surface cover 1 drives the first driving block 51 and the second driving block 52 simultaneously, the driving part 501 moves downwards to drive the reset mechanism 6, and the reset mechanism 6 toggles the switch module 4 to realize the switch state switching.

It can be seen that by the above arrangement of the first driving block 51 and the second driving block 52, it is achieved that any position on the pressing surface cover 1 can control the on-off of the switch.

In some implementations, as shown in fig. 7, the first side position of the panel frame 21 and the second side position of the panel frame 21 have support protrusions 214, respectively, and the support protrusions 214 are configured to overlap the second ends of the first and second driving blocks 51 and 52.

The support protrusions 214 may be continuous integral ribs or may be discontinuous bumps, for example, FIG. 7 illustrates support protrusions 214 arranged in a plurality of spaced apart bumps. The supporting protrusions 214 may slightly protrude from the surface of the panel frame 21, and for example, the protrusion height of the supporting protrusions 214 may be 1mm to 5mm.

The shape of the landing surface of the support protrusions 214 can be a variety of shapes including, but not limited to: rectangular, circular, oval, etc. For example, fig. 7 illustrates that the overlapping surface of the support protrusion 214 is a rectangular surface.

By providing the supporting protrusions 214, not only the second ends of the first and second driving blocks 51 and 52 can be supported, but also the friction between the panel frame 21 and the driving blocks can be reduced, thereby improving the service life of the switch.

In some implementations, as shown in fig. 5-6, the surfaces of the first driving block 51 and the second driving block 52 facing the face cover 1 are provided with arched surfaces 504, and by the design of the arched surfaces 504, the rigidity of the first driving block 51 and the second driving block 52 can be enhanced, so that the first driving block 51 and the second driving block 52 are not easy to deform under stress, the driving stroke is not reduced due to deformation, and the switching function is not effective, and meanwhile, the driving hand feeling of the face cover 1 is improved.

In the embodiment of the present invention, the cover 1 may directly drive the top surfaces of the first driving block 51 and the second driving block 52 through the bottom surfaces thereof, or may indirectly drive the first driving block 51 and the second driving block 52 through other structures.

In some implementations, as shown in fig. 5-6, the first and second drive blocks 51, 52 have first drive protrusions 505 on the surfaces facing the face cover 1; as shown in fig. 11, the cover 1 has a second driving protrusion 11 at a corresponding position, and the second driving protrusion 11 is used to abut against the first driving protrusion 505 to facilitate driving of the cover 1 to the driving mechanism 5.

The first driving protrusion 505 and the second driving protrusion 11 may have the same or different structures, and may have a continuous integral rib or a discontinuous plurality of bumps, for example, the first driving protrusion 505 and the second driving protrusion 11 are each provided to include two or more bumps arranged at intervals.

Further, the bump structures corresponding to the first driving bump 505 and the bump structures corresponding to the second driving bump 11 may be the same or different, for example, fig. 5 illustrates that the bump corresponding to the first driving bump 505 is a circular arc bump, and fig. 11 illustrates that the bump corresponding to the second driving bump 11 is a cross bump.

The first drive protrusions 505 are slightly protruding from the top surface of the drive block and the second drive protrusions 11 are slightly protruding from the bottom surface of the face cover 1, for example, their protrusion heights may be 1mm-5mm.

By providing the first drive projection 505 and the second drive projection 11, the drive of the cover 1 to the drive mechanism 5 is facilitated, while this is particularly advantageous for reducing the pressing stroke of the cover 1 and for lifting the movement stroke of the drive mechanism 5.

In some examples, the first drive protrusion 505 on the first drive block 51 is disposed proximate to the second end of the first drive block 51. And, a first driving protrusion 505 on the second driving block 52 is provided at a position near the second end of the second driving block 52.

For example, the first drive block 51 has a distance from the first end of the first drive protrusion 505 to the first end of the first drive block 51 that is greater than a distance from the first drive protrusion 505 to the second end of the first drive block 51. The arrangement of the first driving protrusion 505 on the second driving block 52 is the same as that described above, and will not be repeated here. This arrangement is particularly advantageous for converting a small stroke of the cover 1 into a large stroke of the drive mechanism 5.

Referring to fig. 12, where O is a rotation axis where the second end of the second driving block 52 is located, O 'is a rotation position of the face cover 1, a is a first driving protrusion 505 of the second driving block 52, a' is a movement position lowest point of the first driving protrusion 505 of the second driving block 52, B is a movement position lowest point of the driving portion 501, C is a center point of the face cover 1 corresponding to the driving portion 501, C 'is a movement position lowest point of a center point of the face cover 1 corresponding to the driving portion 501, D is a position of the second driving protrusion 11 of the face cover 1, and D' is a movement position lowest point of the second driving protrusion 11 of the face cover 1.

Since A is a point on OB, it is apparent that the distance AA 'traveled by the first drive protrusion 505 < the distance BB' traveled by the drive portion 501; since C is a point on O ' D, it is apparent that the travel distance CC ' of the point C < the travel distance DD ' of the second drive projection 11 of the face cover 1; since the second driving protrusion 11 pushes the first driving protrusion 505 of the second driving block 52, the running distance DD 'of the second driving protrusion 11=the running distance AA' of the first driving protrusion 505.

Based on the above, it can be seen that the running distance CC 'of the center point C of the cover 1 is less than the running distance BB' of the driving part 501, which proves that the structural arrangement of the driving mechanism 5 provided by the embodiment of the present invention can realize the conversion of the small stroke of the cover 1 into the large stroke of the driving mechanism 5 and further into the large stroke of the reset mechanism 6. This is favorable to reducing the thickness of switch, makes the switch more slim, promotes switch feel and technological sense.

In some implementations, as shown in fig. 13-14, the reset mechanism 6 includes: the first movable body 61, the second movable body 62, the first elastic body 63, and the second elastic body 64. The first movable body 61 is movably connected to the second movable body 62 and is used for toggling the switch module 4, and the first movable body 61 is configured to be movable relative to the second movable body 62 in a direction parallel to the face cover 1 and movable with the second movable body 62 in a direction perpendicular to the face cover 1. The second movable body 62 is directly or indirectly movably connected to the base assembly 3 and abuts against the driving portion 501, and the second movable body 62 is configured to be movable in a direction perpendicular to the face cover 1 under the driving of the driving portion 501. The first elastic body 63 is used for resetting the first movable body 61 in a direction parallel to the face cover 1; the second elastic body 64 is used to reset the second movable body 62 in the direction perpendicular to the face cover 1.

When the cover 1 is pressed, the driving mechanism 5 drives the second movable body 62 downward through the driving part 501 to move downward, and the second movable body 62 moving downward drives the first movable body 61 to move downward along with the second movable body, so that the first movable body 61 moves to be capable of toggling the switch module 4, and since the toggling direction of the switch module 4 is generally along the left-right direction, the first movable body 61 moves in the direction parallel to the cover 1 along with the switch module 4 (i.e. moves left-right) during toggling.

The first elastic body 63 is used to reset the first movable body 61 in a direction parallel to the face cover 1 after the pressing of the face cover 1 is canceled; the second elastic body 64 is used for enabling the second movable body 62 to move upwards in a reset mode, and meanwhile, driving the first movable body 61 to move upwards in a reset mode. Finally, the reset mechanism 6 is reset to the initial state.

Illustratively, as shown in fig. 13, two sets of first toggle portions 610 are symmetrically arranged on both sides of the end portion of the first movable body 61; the switch module 4 comprises a transition piece 41, two groups of second poking parts 410 which are symmetrically arranged are arranged on two sides of the end part of the transition piece 41, and the second poking parts 410 are in one-to-one correspondence with the first poking parts 610.

One side of the two groups of first poking parts 610 facing each other is respectively provided with a first poking surface 6100 which is obliquely arranged; the sides of the two groups of second poking parts 410, which are away from each other, are respectively provided with second poking surfaces 4100 which are obliquely arranged; the first toggle surface 6100 is configured to abut against the corresponding second toggle surface 4100, so as to toggle the second toggle portion 410 by the first toggle portion 610.

When the face cover 1 is in a natural state, the first stirring part 610 and the corresponding second stirring part 410 are provided with a space; when the face cover 1 is in a pressed state, one group of first poking parts 610 can poke one group of second poking parts 410 positioned on the same side, and the other group of first poking parts 610 can move into a clearance cavity accommodated between the two groups of second poking parts 410.

As shown in the first left-hand state diagram of fig. 15, when the cover 1 is in the natural state, the reset mechanism 6 is also in the natural state, and a certain distance exists between the reset mechanism 6 and the transition piece 41 in the vertical direction.

It will be appreciated that when the switch is in either the on or off state, one of the two sets of second toggle portions 410 on its transition piece 41 is in the uppermost position and the other is in the lowermost position. When the state of the switch needs to be switched, the transition piece 41 is shifted to rotate, so that the second shifting part 410 at the highest position rotates to the lowest position, and the other second shifting part 410 at the lowest position correspondingly rotates to the highest position, thereby completing shifting of the transition piece 41.

The manner in which the reset mechanism 6 is moved to effect transition piece 41 will be described below in connection with fig. 15.

When the cover 1 is in the pressed state, the reset mechanism 6 moves downward by a certain distance under the driving of the driving mechanism 5, and the first toggle portion 610 located at the left toggles the second toggle surface 4100 of the second toggle portion 410 located at the left by virtue of the first toggle surface 6100 thereof (see the second state diagram from the left in fig. 15).

The second stirring portion 410 is stirred to enable the transition piece 41 to rotate along the anticlockwise direction (see a third state diagram from the left side of fig. 15), as the reset mechanism 6 continues to descend, the first stirring portion 610 at the left side is always abutted against the second stirring portion 410 at the left side to realize mutual driving of the two (the first stirring portion 610 drives the second stirring portion 410 to rotate anticlockwise, meanwhile, the second stirring portion 410 drives the first stirring portion 610 to translate leftwards), until the transition piece 41 moves to the right (see a fourth state diagram from the left side of fig. 15), stirring is completed, and state switching of the switch module 4 is realized. At this time, the first striking part 610 located at the right side moves into the gap cavity accommodated between the two sets of second striking parts 410, i.e., the first striking part 610 located at the right side is located at the inner side of the second striking part 410 located at the right side.

After the pressing of the cover 1 is released, the first elastic body 63 drives the first movable body 61 to reset upwards and then drives the second movable body 62 to reset upwards together, and the second elastic body 64 drives the second movable body 62 to reset leftwards, so that the reset mechanism 6 is reset to a natural state.

In the resetting process, since the first striking part 610 on the left side is located at the outer side of the second striking part 410 on the left side and the first striking part 610 on the right side is located at the inner side of the second striking part 410 on the right side, the first striking part 610 can freely move upward without interfering with the transition piece 41, that is, the resetting process of the resetting mechanism 6, the driving mechanism 5 and the face cover 1 does not affect the on-off state of the switch module 4.

When the cover 1 is pressed again, since the transition piece 41 has been rotated counterclockwise to make the position of the second stirring portion 410 on the right side slightly higher, at this time, the reset mechanism 6 uses the first stirring portion 610 on the right side to stir the second stirring portion 410 on the right side, and the stirring process is similar to the above, which will not be described again, and finally, the transition piece 41 is moved clockwise to complete another stirring, so as to realize the state switching of the switch module 4 again.

Regarding the arrangement of the first elastic body 63 and the second elastic body 64 in the switch, reference is made to the following explanation.

In the embodiment of the present invention, the number of the first elastic bodies 63 may be one or more, and the first elastic bodies 63 may be used to reset the first movable body 61 in a direction parallel to the face cover 1, that is, the first elastic bodies 63 may be sufficient to provide elastic force to the first movable body 61 in the horizontal direction.

For example, fig. 14 illustrates that the return mechanism 6 is symmetrically arranged with two first elastic bodies 63, and the first elastic bodies 63 may be compression springs. The second movable body 62 is provided with a first receiving groove 621, and the first receiving groove 621 is configured to be able to receive the main body portion of the first movable body 61 and allow it to move in the horizontal direction. Two second accommodating grooves 622 are symmetrically arranged on two sides of the second movable body 62, two third accommodating grooves 611 are symmetrically arranged on the wall of the first movable body 61, and the second accommodating grooves 622 and the corresponding third accommodating grooves 611 are matched to form elastomer accommodating grooves.

A part of the first elastic body 63 is located in the second accommodating groove 622, the other part is located in the third accommodating groove 611, and two ends of the first elastic body 63 are respectively abutted against the corresponding groove walls. In this way, when the first movable body 61 moves in the horizontal direction, the first elastic body 63 is compressed, thereby storing elastic potential energy to facilitate the return of the first movable body 61 in the first direction, and the first elastic bodies 63 are symmetrically arranged in two so that the return driving force to the first movable body 61 is more balanced, preventing the return mechanism 6 from failing.

In the embodiment of the present invention, the number of the second elastic bodies 64 may be one or more, and the second elastic bodies 64 may be used to reset the second movable body 62 in the direction perpendicular to the face cover 1, that is, the second elastic bodies 64 may be sufficient to provide elastic force to the second movable body 62 in the vertical direction.

For example, fig. 14 illustrates that the return mechanism 6 is symmetrically arranged with two second elastic bodies 64, and the second elastic bodies 64 may be compression springs. The two second elastic bodies 64 are arranged along the diagonal direction of the second movable body 62, so that the reset driving force of the second movable body 62 is more balanced on the premise of reducing the number of the second elastic bodies 64, and the reset mechanism 6 is prevented from being disabled.

The upper end of the second elastic body 64 abuts against or is connected to the second movable body 62, and the lower end of the second elastic body 64 abuts against or is connected to the base assembly 3 or a housing body 65 described below. Further, the second elastic body 64 may be positioned by a shaft or a sleeve.

In some implementations, as shown in fig. 13, the reset mechanism 6 further includes: the accommodating body 65, the accommodating body 65 is fixed in the base assembly 3, and the accommodating body 65 is used for accommodating the second movable body 62 and positioning the second movable body 62 in a direction parallel to the face cover 1.

The accommodating body 65 may be fixed in the pressing plate 31 of the base assembly 3 by a snap connection, or a screw connection, etc., and the accommodating body 65 provides an accommodating cavity to accommodate the second movable body 62 and the second elastic body 64.

One example is to limit the second movable body 62 by using the inner wall of the cavity of the accommodating body 65, and another example is to limit the second movable body 62 by providing a limiting shaft in the cavity of the accommodating body 65 and providing a limiting hole in the wall of the second movable body 62 to accommodate the limiting shaft. Eventually, the second movable body 62 can move only in the direction perpendicular to the face cover 1, but cannot move in the direction parallel to the face cover 1.

As described above, the two second elastic bodies 64 are arranged along one diagonal direction of the second movable body 62, and the two limiting holes may be arranged along the other diagonal direction of the second movable body 62, and the limiting shafts are provided at the corresponding positions in the cavity of the accommodating body 65, so as to achieve the purpose of satisfying various functions while simplifying the structural arrangement of the reset mechanism 6.

In some implementations, a resilient return member may be further arranged for the drive mechanism 5, for example, a return spring is provided below the first drive block 51 and the second drive block 52, thereby increasing the return force of the drive mechanism 5.

In some implementations, a resilient return member may be further disposed with respect to the cover plate, for example, another return spring may be disposed under the cover plate to increase the return force of the cover plate. In addition, as mentioned above, the driving mechanism 5 is arranged on the panel frame 21, and in other examples, it is also possible to arrange the driving mechanism 5 on the pressing plate 31.

In summary, the switch provided by the embodiment of the invention has at least the following advantages based on the design: the realization has pure flat outward appearance, reduces the stroke of pressing, makes the feel more near electronic switch, promotes the feel and realizes the switch slimming, can operate the switch in the optional position of face lid, and convenience of customers uses, promotes user experience.

In embodiments of the present invention, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. The term "plurality" refers to two or more, unless explicitly defined otherwise.

The foregoing description is only for the convenience of those skilled in the art to understand the technical solution of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
