Specific embodiments thereof have been shown by way of example in the drawings and will herein be described in more detail. These drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments.

Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

Orientation terms such as "upper", "lower", "side", etc. in the embodiments of the present invention are generally based on the relative relationships of orientations shown in fig. 1 and 2, and are used merely to more clearly describe structures and relationships between structures, and are not intended to describe absolute orientations. The orientation may change when the product is placed in different orientations, e.g. "up", "down" may be interchanged.

In the embodiment of the invention, the position of the button in the switch is defined as upper or top, the position of the functional module is defined as lower or bottom, and the rotation of the button and the rotating piece is defined as rotating along the vertical direction, so that the movable contact block moves along the downward direction until the movable contact contacts the stationary contact, or the movable contact block moves along the upward direction until the movable contact is far away from the stationary contact. When a direction perpendicular to the vertical direction is defined as a horizontal direction, for example, when the switch includes an N-pole functional module and an L-pole functional module, the N-pole functional module and the L-pole functional module are sequentially distributed along the horizontal direction.

Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meaning as commonly understood by those of ordinary skill in the art, and both the moving contact and the stationary contact referred to in the embodiments of the present invention may be regarded as silver points known in the art. In order to make the technical scheme and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail with reference to the accompanying drawings.

However, for the current rocker switch, there are at least the following technical problems:

(1) In order to make the pin assembly slide on the rocker smoothly, the pressure between the pin assembly and the rocker needs to be set to be small, which makes the contact resistance between the moving contact and the static contact relatively large, and thus makes the bearing current of the rocker switch small, for example, the maximum bearing current of a common rocker switch is 16A.

(2) In the turn-on process of the rocker switch, the movable contact and the static contact collide quickly, the quick collision of the movable contact and the static contact can generate bouncing, arc discharge is generated, and the movable contact and the static contact are burnt out easily. In addition, the fast collision of moving and static contacts makes the wane can produce the spring, because the incoming wire terminal supporting piece on the incoming wire terminal subassembly supports the wane, and the jump of wane can make the support department separation of both like this, and then produces and draws the arc, this burns out the incoming wire terminal supporting piece easily.

(3) In the disconnection process of the rocker switch, the transition piece drives the marble component on the rocker to slide on the rocker, when the marble component is scratched through the center of the rocker, the rocker starts to turn over, the turning force of the rocker is changed from small to large, the contact pressure between the movable contact and the static contact is slowly changed into small in the process, the separation of the movable contact and the static contact is not rapid, arc discharge is easy to occur, and the movable contact and the static contact are easy to burn out.

In particular, the embodiment of the invention provides a switch aiming at the bouncing problem generated during the rapid collision of a movable contact and a stationary contact. Fig. 1 illustrates a combined view of the switch, fig. 2 illustrates a sectional view of the switch, and fig. 3 and fig. 4 illustrate partial structural schematic views of the switch with the housing 1 removed, respectively. As shown in fig. 1 to 4, the switch includes: the multifunctional electric power device comprises a shell 1, a button 2, a supporting body 3 positioned in the shell 1, a transmission module 01, a functional module 7 and a torsion spring 8, wherein the functional module 7 comprises a movable contact block 71 with a movable contact 710 and a fixed contact 730 matched with the movable contact 710, the switch is turned on when the movable contact 710 moves to be in contact with the fixed contact 730, and conversely, the switch is turned off when the movable contact 710 moves to be separated from the fixed contact 730.

The button 2 is hinged to the housing 1, the transmission module 01 is movably connected to the support body 3, the button 2 is further connected to the movable contact block 71 through the transmission module 01, and the transmission module 01 is configured to convert rotation of the button 2 into rotation of the movable contact block 71, so that the movable contact 710 approaches to or departs from the stationary contact 730.

That is, the push button 2 is pressed to rotate, so that the movable contact block 71 moves correspondingly through the transmission module 01, and the movable contact 710 on the movable contact block 71 approaches to or moves away from the stationary contact 730, so that the switch is turned on or off.

As shown in fig. 3 or fig. 4, the torsion spring member 8 is disposed between the transmission module 01 and the movable contact block 71, and the torsion spring member 8 is configured to apply a pressure to the end portion of the movable contact block 71 where the movable contact 710 is located, toward the stationary contact 730.

According to the switch provided by the embodiment of the invention, the torsion spring 8 is arranged, and the torsion spring 8 can apply pressure to the end part of the movable contact 710 of the movable contact block 71, which is close to the fixed contact 730, so that the movable contact block 71 rotates locally under the action of the torsion spring 8, and the switch has at least the following advantages: the spring problem existing when the movable contact and the static contact are contacted is reduced, the contact pressure between the movable contact 710 and the static contact 730 can be increased, the movable contact 710 and the static contact 730 are quickly disconnected, the movable contact 710 and the static contact 730 are enabled to collide with each other in the front, and the deflection is prevented. The advantages are improved contact effect of moving and static contacts, increased load current and optimized on-off performance.

For example, as shown in fig. 5, the movable contact block 71 includes a first connection section 711, a hinge section 712 and a second connection section 713 sequentially connected, the first connection section 711 is electrically connected to the incoming line terminal assembly 72 of the functional module 7, further, as can be seen in fig. 6, the hinge section 712 is connected to the first connection portion 41 of the transmission module 01 through a pin 91 (such that the hinge section 712 can rotate relative to the first connection portion 41), and a movable contact 710 is disposed on a bottom wall of one end of the second connection section 713 away from the hinge section 712.

As shown in fig. 6, the torsion spring member 8 includes: a spring body 81, and a first arm 82 and a second arm 83 connected to both sides of the spring body 81, respectively; the spring body 81 is connected to the first connecting portion 41, the first arm 82 abuts on a wall of the rotor 4 adjacent to the first connecting portion 41, and the second arm 83 abuts on a top wall of the second connecting section 713, so that the second connecting section 713 provided with the movable contact 710 is depressed. The above arrangement of the torsion spring member 8 is advantageous in that the torsion spring member 8 is kept in a compressed state all the time.

In some implementations, as shown in fig. 6, the first connection portion 41 includes: two hinge blocks 411 are symmetrically arranged, and a containing cavity is arranged between the two hinge blocks 411. The hinge section 712 is connected with the two hinge blocks 411 in the accommodating cavity through a pin shaft 91; the spring body 81 is located at the hinge block 411 or the pin 91.

The spring body 81 may be disposed on the hinge block 411 or on the pin 91, so that the first arm 82 and the second arm 83 can be pressed when the hinge segment 712 rotates, so that the torsion spring 8 is compressed or stretched appropriately.

In some examples, as shown in fig. 6, the hinge block 411 includes a hinge portion 4111 and a boss portion 4112, and the boss portion 4112 is connected with the hinge portion 4111 in the housing cavity. The hinge section 712 is located between the two shaft housing portions 4112, and the pin 91 may penetrate through both the two hinge blocks 411 and the hinge section 712, or may only penetrate through the hinge section 712, and both ends of the hinge section are located in the shaft housing portions 4112, so that the movable contact block 71 and the first connection portion 41 may be hinged.

It will be appreciated that the hinge portion 4111, the shaft housing portion 4112 and the hinge segment 712 of the movable contact block 71 have shaft holes sequentially communicated with each other, and the pin shaft 91 penetrates the shaft holes so that the hinge segment 712 can rotate in the receiving chamber. The spring body 81 is sleeved on the at least one shaft housing 4112, and the first arm 82 abuts against the stop wall 4001 of the accommodating cavity facing the shaft housing 4112.

The spring body 81 may be sleeved on only one shaft sleeve portion 4112, or the spring body 81 may be sleeved on both shaft sleeve portions 4112, and the spring body 81 is provided on both shaft sleeve portions 4112 at the same time, so that the pressure of the torsion spring member 8 on the movable contact block 71 is more balanced, and the spring body 81 is provided on both shaft sleeve portions 4112 as described in the following example:

as shown in fig. 7, the spring body 81 includes: a first spring body 811 and a second spring body 812 which are arranged opposite to each other and independent of each other; the first arm 82 includes: a first abutting arm 821 and a second abutting arm 822 which are arranged opposite to each other and independent from each other; the second arm portion 83 includes: a first side arm segment 831, an abutment arm segment 832 and a second side arm segment 833 connected in sequence.

The first abutting arm 821 and the first side arm section 831 are respectively connected to both sides of the first spring body 811, and the second abutting arm 822 and the second side arm section 833 are respectively connected to both sides of the second spring body 812; as can be seen from fig. 6, the first spring body 811 and the second spring body 812 are respectively sleeved on the shaft sleeve portion 4112, the first abutting arm 821 and the second abutting arm 822 are both abutted against the stop wall 4001 and located at two sides of the hinge section 712, the first side arm section 831 and the second side arm section 833 are respectively located at two sides of the second connecting section 713, and the abutting arm section 832 is abutted against the top wall of the second connecting section 713.

The torsion spring member 8 of the above-described structural arrangement may be formed by bending a wire having high elasticity, the first abutting arm 821 and the second abutting arm 822 of which are in a single rod shape and symmetrically abut against the stopper wall 4001, and the second arm 83 of which is in a U-shaped rod shape and surrounds three sides of the second connecting section 713 and abuts against the top wall of the second connecting section 713.

In the embodiment of the invention, the torsion spring member 8 is always in a compressed state, when the switch is in an on state, the torsion spring member 8 is in a first compressed state, and when the switch is in an off state, the torsion spring member 8 is in a second compressed state, and the compression degree corresponding to the second compressed state is smaller than that corresponding to the first compressed state.

The second arm 83 applies the elastic potential energy stored by the torsion spring member 8 downward to the second connection section 713 of the movable contact block 71, so that the second connection section 713 of the movable contact block 71 is always heavier relative to the first connection section 711 thereof. When the switch is switched from the off state to the on state, the heavier second connection section 713 facilitates the front collision of the movable contact 710 and the stationary contact 730 and increases the contact pressure between the movable contact 710 and the stationary contact 730.

Further exemplary descriptions of the arrangement of the torsion spring member 8 are provided below, further in connection with the structure of the transmission module 01:

As shown in fig. 1 to fig. 4, the transmission module 01 includes a rotating member 4, a link member 5 and an elastic member 6, and as shown in fig. 2 and fig. 3, the rotating member 4 is movably connected to the supporting body 3, so that the rotating member 4 can rotate with a first end of the rotating member 4 as a rotation shaft 400, and a second end of the rotating member 4 is connected to the movable contact block 71 through a first connection portion 41. The rotating member 4 integrally rotates with its first end as the rotating shaft 400, so that the second end of the rotating member 4 further drives the movable contact block 71 to move up and down, so that the movable contact 710 thereon approaches or moves away from the stationary contact 730.

The first end of the link member 5 is rotatably connected with the first connection position 201 of the button 2, and the second end of the link member 5 is rotatably connected with the second connection portion 42 of the rotating member 4; and, the first end of the elastic member 6 is connected to the second connection location 202 of the button 2, and the second end of the elastic member 6 is connected to the third connection portion 43 of the rotating member 4. The link member 5 and the elastic member 6 can convert the rotation of the push button 2 into the rotation of the rotation member 4, thereby bringing the movable contact 710 on the movable contact block 71 close to or away from the stationary contact 730.

In particular, in the on-state of the switch, the elastic element 6 is in a first stretched state, and the pushbutton 2 is stopped in the closed position by the combined action of the link element 5 and the housing 1. And, in the switch-off state, the elastic member 6 is in the second stretched state, and the push button 2 is stopped at the opening position under the combined action of the link member 5 and the housing 1.

The first stretched state of the elastic member 6 has a greater degree of stretch than the second stretched state, and the degree of stretch may be considered as the total length of the elastic member 6 in each stretched state, i.e., the stretched length. It can be seen that the elastic member 6 has a longer extension in the switch-on state than in the switch-off state.

According to the switch provided by the embodiment of the invention, the rotating piece 4, the connecting rod piece 5 and the elastic piece 6 are arranged between the button 2 and the movable contact block 71, and the button 2 is pressed to rotate between a closing position corresponding to the on state of the switch and a separating position corresponding to the off state of the switch. The rotating button 2 acts on the link member 5 and the elastic member 6 respectively, and drives the rotating member 4 to rotate, so that the movable contact 710 and the stationary contact 730 are finally contacted or separated, and the purpose of switching on or switching off the functional module 7 is achieved. When the switch is in the on state, the elastic member 6 is in the first stretching state, the push button 2 is unbalanced by the stretching action of the elastic member 6 at the closing position, and at this time, the push button 2 is stopped by the link member 5 and the housing 1 to overcome the unbalance, so that the push button 2 is stabilized at the closing position. Since the elastic member 6 is in the first stretching state, the elastic member 6 will press the rotating member 4, and the pressing force directly acts on the moving contact 710 through the rotating member 4, so as to increase the contact pressure between the moving contact 710 and the stationary contact 730, and further reduce the contact resistance between the moving contact 710 and the stationary contact 730, so that the switch provided by the embodiment of the invention can bear larger current.

For example, the load current is at least greater than 16A, and further, the load current of the switch is large enough that the switch can be applied to electrical devices such as kitchen appliances, air conditioners, and the like.

Since the corresponding stretching degree of the elastic member 6 in the switch-on state is greater than that in the switch-off state, when the switch is switched from the switch-on state to the switch-off state, the push button 2 is pressed to rotate towards the switch-off position, the elastic member 6 has a momentary resetting trend and rapidly pulls the rotating member 4 upwards, the rotating member 4 rapidly rotates upwards and drives the movable contact block 71 to rapidly move upwards, and the movable contact 710 and the stationary contact 730 are further rapidly separated, so that the arcing problem of the movable contact 710 and the stationary contact 730 in the switch-off process is effectively avoided.

When the switch is in the off state, the elastic member 6 is in the second stretched state, and the push button 2 is unbalanced by the stretching action of the elastic member 6 at the opening position, and at this time, the push button 2 is stopped by the link member 5 and the housing 1 to overcome the unbalance, so that the push button 2 is stabilized at the opening position.

When the switch is switched from the off state to the on state, the button 2 is pressed to rotate towards the on position and stretch the elastic piece 6 again, meanwhile, the connecting rod piece 5 pushes the rotating piece 4 to move downwards, in the process, the stretched elastic piece 6 acts on the rotating piece 4 in a reaction mode, the rotating piece 4 drives the movable contact block 71 to move downwards rapidly, the movable contact 710 and the fixed contact 730 are in rapid contact, under the pushing action of the stretched elastic piece 6, the movable contact 710 and the fixed contact 730 cannot bounce even in rapid collision, and further the arcing problem of the movable contact 710 and the fixed contact 730 in the on process is effectively avoided.

In summary, according to the switch provided by the embodiment of the invention, the rotating member 4, the link member 5 and the elastic member 6 are arranged between the button 2 and the movable contact block 71, and the rotating button 2 drives the rotating member 4 to rotate through the link member 5 and the elastic member 6, so that the movable contact 710 and the stationary contact 730 are contacted or separated. Since the elastic member 6 is always in a stretched state when the switch is turned on and off, it is not only beneficial to increasing the contact pressure between the movable contact 710 and the stationary contact 730 and remarkably improving the load current of the switch, but also beneficial to quickly separating the movable contact 710 from the stationary contact 730 during the switch off process, so as to avoid arcing, and beneficial to quickly colliding the movable contact 710 and the stationary contact 730 during the switch on process without bouncing, and further improving the arcing problem.

The switch provided by the embodiment of the invention has the advantages of high bearing current, rapid breaking between the movable contact 710 and the fixed contact 730, avoiding the arcing problem, long service life and the like, and also has the advantages of fewer parts, simple structure and assembly, high transmission efficiency and the like.

The switch provided by the embodiment of the invention can be a single-pole switch or a bipolar switch, and the bipolar switch can simultaneously switch on or off a live wire and a zero wire. In order to enable the forces applied by the elastic member 6 and the link member 5 in the switch to be kept in an equilibrium state, the switch provided by the embodiment of the present invention may be designed as a bipolar switch, and the following exemplary descriptions are respectively given for each component involved in the bipolar switch and the assembly relationship thereof:

As shown in fig. 9, the rotating member 4 includes: the body portion 40, the two first connecting portions 41, the two second connecting portions 42, and the third connecting portion 43 are rotated. Wherein, the first end of the rotating body part 40 is used as a rotating shaft 400 to be lapped on the supporting body 3; the second end of the rotating body portion 40 is connected with two first connecting portions 41 and a third connecting portion 43 at the same time, and the two first connecting portions 41 are symmetrically distributed on two sides of the third connecting portion 43. Two second connection portions 42 are connected to the top wall of the rotating body portion 40, and the two second connection portions 42 are disposed opposite to each other on two sides of the rotating body portion 40. The movable contact block 71 comprises an N-pole movable contact block 71 and an L-pole movable contact block 71 which are symmetrically arranged, wherein the N-pole movable contact block 71 is connected with one of the first connecting parts 41, and the L-pole movable contact block 71 is connected with the other first connecting part 41.

Through making two first connecting portions 41 and two second connecting portions 42 equipartition place the second end of rotating member 4, utilize first connecting portion 41 to connect elastic component 6, utilize two second connecting portions 42 to connect N utmost point movable contact piece 71 and L utmost point movable contact piece 71, in this way, the effort of elastic component 6 in tensile state will more directly high-efficiently transmit to N utmost point movable contact piece 71 and L utmost point movable contact piece 71 through rotating member 4 for movable contact 710 and stationary contact 730 break and obtain bigger contact pressure fast.

Furthermore, the third connection portion 43 is arranged centrally between the two first connection portions 41, and the elastic member 6 is arranged centrally in the switch such that the forces it exerts on the N-pole movable contact block 71 and the L-pole movable contact block 71 are balanced. By arranging the two second connection portions 42 on the top wall of the rotating body portion 40 between the both ends, not only the pulling and pushing of the rotating member 4 by the link member 5 can be ensured, but also the support can be applied to the entirety of the rotating member 4 and the push button 2 to keep the positions of both in the switch-on state and the switch-off state stable.

Further by way of example, as shown in fig. 10, the rotating body portion 40 includes an N-pole connecting portion 401, an intermediate connecting portion 402, and an L-pole connecting portion 403 connected in this order, wherein both sides of the intermediate connecting portion 402 form a gap cavity 404 with the N-pole connecting portion 401 and the L-pole connecting portion 403, respectively.

The N pole connecting part 401 and the L pole connecting part 403 have the same structure, the second ends of the N pole connecting part 401 and the L pole connecting part 403 are respectively connected with a first connecting part 41, and the middle parts of the N pole connecting part and the L pole connecting part are respectively connected with a second connecting part 42; a third connection portion 43 is connected to a second end of the intermediate connection portion 402; the rotation shaft 400 is commonly provided by first ends of an N-pole connection portion 401, an intermediate connection portion 402, and an L-pole connection portion 403.

In some examples, as shown in fig. 10, a first end of the rotating body portion 40, which is the rotating shaft 400, is at an angle of more than 90 ° and less than 180 ° with respect to the other portions of the rotating body portion 40, for example, 110 °, 115 °, 120 °, 125 °, 130 °, and the like. In this way, the first end of the rotating body portion 40 is arranged obliquely with respect to the other portions of the rotating body portion 40, so that the rotation of the rotating member 4 is smoother and interference with the supporting body 3 can be avoided.

As shown in fig. 3, when the switch is in the on state, the other portion of the rotating body portion 40 than the first end is disposed horizontally, and the first end of the rotating body portion 40 is disposed tilted upward with respect to the other portion.

As described above, each first connecting portion 41 includes two hinge blocks 411, one end of each hinge block 411 is connected to the second end of the rotating body portion 40, a receiving cavity is formed between the two hinge blocks 411, an end of the receiving cavity away from the stopper wall 4001 has an opening through which the second connecting section 713 of the torsion spring member 8 protrudes to the outside of the receiving cavity.

The side wall of the second end of the rotating body portion 40 of the rotating member 4, which is located inside the accommodating cavity, serves as the above-mentioned stop wall 4001, and further, the top wall of the second end of the rotating body portion 40, which is located between the two hinge blocks 411, is provided with a groove 4003, and the groove 4003 is used for accommodating the end portion of the first arm portion 82, so that not only is the installation of the torsion spring member 8 facilitated, but also during the switching-on process of the switch, the stop wall 4001 presses the first arm portion 82 to rotate, and the groove 4003 accommodates the end portion of the first arm portion 82, which is beneficial for the torsion spring member 8 to be rapidly compressed.

As shown in fig. 5, the movable contact block 71 includes a first connection section 711, a hinge section 712, and a second connection section 713 connected in sequence; the hinge section 712 is connected with the first connecting portion 41 in the accommodating cavity through the pin 91; the first connecting section 711 extends to the lower part of the rotating body part 40 through the accommodating cavity on the first connecting part 41, and the first connecting section 711 is electrically connected with the wire inlet terminal assembly 72 of the functional module 7; the second connection section 713 extends to the outside of the rotating body part 40 through the accommodation cavity on the first connection part 41, and a movable contact 710 is provided on a bottom wall of one end of the second connection section 713 located outside the rotating body part 40.

When the switch is switched from the on state to the off state, the movable contact 710 is separated from the stationary contact 730, at this time, the second connection section 713 provided with the movable contact 710 is rotated downward by a certain angle (i.e., partially rotated) under the reset action of the torsion spring member 8, and since the first connection section 711 extends below the rotating body portion 40, the top wall of the first connection section 711 abuts against the bottom wall at the corresponding position of the rotating body portion 40, thereby playing a limiting role, and the torsion spring member 8 can be prevented from being completely reset, so that the torsion spring member 8 is still in the second compressed state in the off state of the switch.

Further, as shown in fig. 8, in the switch-on state, a gap H is provided between the top wall of the first connection section 711 and the bottom wall at the corresponding position of the rotating body portion 40, the gap H allowing the movable contact 71 to have a set rotational margin.

By the arrangement, even if the silver points of the switch are ablated during normal use, the movable contact block 71 can adaptively keep close to the fixed contact 730 based on the gap, so that normal contact and stable pressure between the movable contact 710 and the fixed contact 730 are maintained, the switch is ensured to be stably turned on, soft spring rather than hard spring of the movable contact 710 and the fixed contact 730 is facilitated, the contact loss speed of the contacts is reduced, and the service life of the contacts is prolonged.

In some examples, the gap is 0.3mm to 0.5mm in size, e.g., 0.3mm, 0.35mm, 0.4mm, 0.45mm, etc.

The connection between the second connection portion 42 and the link member 5 is exemplarily described below:

as shown in fig. 10, the second connection portion 42 includes: the first end of the limiting block 421 is connected with the top wall of the rotating body part 40, and the second end of the limiting block 421 is located above the rotating body part 40, so that a rotating groove 422 with a side opening 4220 is formed between the limiting block 421 and the rotating body part 40; the second connection portion 42 is configured to allow the second end of the link member 5 to enter the rotation groove 422 through the side opening 4220 and rotate the second end of the link member 5 within the rotation groove 422.

Through forming the rotation groove 422 between stopper 421 and rotating body portion 40, the second end of connecting rod piece 5 can carry out corresponding rotation along with the rotation of button 2 in rotation groove 422, simultaneously, connecting rod piece 5 still can pull up stopper 421 or push away rotating body portion 40 when rotating, and then drive and rotate piece 4 and rotate. In addition, the side opening 4220 facilitates assembly of the link member 5 therein.

As described above, the rotating body portion 40 includes the N-pole connecting portion 401, the intermediate connecting portion 402, and the L-pole connecting portion 403, which are connected in this order, and the two second connecting portions 42 each include: the stopper 421 and the rotation groove 422, wherein a first end of one stopper 421 is connected with the top wall of the N-pole connecting portion 401, and a second end thereof is located above the N-pole connecting portion 401, and a first end of the other stopper 421 is connected with the top wall of the L-pole connecting portion 403, and a second end thereof is located above the L-pole connecting portion 403.

Further, the groove wall of the rotation groove 422 on the opposite side to the side opening 4220 thereof is in the shape of a circular arc for guiding the rotation of the second end of the link member 5, and in some examples, the groove wall in the shape of a circular arc may be formed inside the first end of the stopper 421. With this arrangement, it is advantageous to make the rotation process of the link member 5 more efficient and smooth.

In some examples, the stopper 421 is arranged obliquely such that the longitudinal dimension of the rotation groove 422 gradually increases in a direction approaching the side opening 4220, i.e., the rotation groove 422 is grooved obliquely upward.

For example, the first end of the stopper 421 is a circular arc surface, the bottom wall of the other portion of the stopper 421 except the first end thereof is an inclined surface, the top wall of the rotating body portion 40 is a plane, and the distance between the bottom wall of the stopper 421 and the top wall of the rotating body portion 40 gradually increases from the first end of the stopper 421 to the second end of the stopper 421, so as to gradually increase the longitudinal dimension of the rotating slot 422 along the direction approaching the side opening 4220. By the above arrangement, the side opening 4220 is maximized in size, which facilitates the fitting of the link member 5 into the rotation groove 422.

The following will exemplify the mode of action between the rotating member 4 and the link member 5, in conjunction with the structure of the link member 5:

in some implementations, as can be seen in connection with fig. 11, the link member 5 includes: a first shaft section 51, a first side support section 52, a second shaft section 53, and a second side support section 54 connected in sequence; as can be seen from fig. 12, both sides of the first shaft section 51 are rotatably connected to a first connection position 201, respectively; both sides of the second shaft section 53 are rotatably connected to a second connecting portion 42, respectively.

The link member 5 has a rectangular frame-like structure, so that the rotational force of the push button 2 can be more uniformly and efficiently applied to the rotary member 4.

The first connection locations 201 on the push button 2 are designed to be hole-shaped, and in some examples, two first connection locations 201 are symmetrically arranged on both sides of the push button 2. In other examples, the first connection bit 201 is arranged only as one, and both ends thereof extend to both sides of the button 2, respectively, for example, the first connection bit 201 is in a long through-hole shape.

In some examples, the first shaft section 51 may be a complete rod (not shown), in which case the first connection location 201 on the button 2 is a partially open hole, the bottom of which is provided with a bottom opening through which the first shaft section 51 enters into the first connection location 201.

In some examples, as shown in fig. 11, the first shaft section 51 has a notch 510, and the portions of the first shaft section 51 located at both sides of the notch 510 are connected to the first connection locations 201, so that the portions of the first shaft section 51 located at both sides of the notch 510 are rotatably connected to one first connection location 201 when the first connection locations 201 are symmetrically arranged. For example, a notch 510 is provided at a middle position of the first shaft section 51 such that the first shaft section 51 includes two parts located at both sides of the notch 510. In this case, the first connection locations 201 on the button 2 may be closed holes, and of course, one or both of the first connection locations 201 may be partially open holes.

When the assembly is carried out, the end, close to the notch 510, of the first shaft section 51 is inserted into the corresponding first connecting position 201.

The first shaft section 51 and the second shaft section 53 are both cylindrical, and the first side support section 52 and the second side support section 54 may be cylindrical structures, or may be other rod-shaped structures, such as rectangular rod bodies. In some examples, the first shaft section 51 has a notch 510, and is bent by a cylindrical metal rod to form the link member 5.

In connection with the link member 5 of the above-described structure, the manner in which the link member 5 acts on the rotary member 4 will be exemplarily described:

as shown in fig. 4, during the opening process of the switch, the button 2 is pressed to rotate, the link member 5 rotates along with it and the second shaft section 53 thereof rotates upward along the rotation groove 422, and the stopper 421 is pulled upward, so that the rotating member 4 rotates upward until the button 2 rotates to the opening position, and the distance that the rotating member 4 rotates upward reaches the maximum. At this time, the first shaft section 51 of the link member 5 pulls down the push button 2, the second shaft section 53 pulls up the rotary member 4, and the push button 2 reaches a position balance at the opening position by the pull-down action of the link member 5.

Although the elastic member 6 in the extended state tends to unbalance the push button 2, a stopper is provided on the housing 1 to stop the push button 2 so as to cancel the unbalance, thereby ensuring that the push button 2 is stabilized in the opening position. In the switch-off state, the vertical distance between the first and second shaft sections 51, 53 of the link member 5 is minimized, both of which apply more force to the push button 2 and the rotary member 4 in the horizontal direction, and in some examples, the tilt directions of the first and second side support sections 52, 54 of the link member 5 are made substantially parallel to the tilt direction of the button body 21.

As shown in fig. 3, during the turning-on of the switch, the push button 2 is pressed to rotate, the link member 5 rotates therewith and the second shaft section 53 thereof rotates downward along the rotation groove 422, and the rotating member 4 is pressed downward until the push button 2 rotates to the closing position, and the downward rotation distance of the rotating member 4 reaches the maximum. At this time, the first shaft section 51 of the link member 5 pushes the push button 2, the second shaft section 53 pushes the rotary member 4 down, and the push button 2 reaches a position balance at the closing position under the pull-down action of the link member 5.

Although the elastic member 6 in the extended state tends to unbalance the push button 2, the other first stopper 101 is disposed on the housing 1 to stop the push button 2 so as to cancel the unbalance, thereby ensuring that the push button 2 is stabilized in the closing position. In the switch-on state, the vertical distance between the first and second shaft sections 51, 53 of the link member 5 is maximized, both of which apply more force to the push button 2 and the rotary member 4 in the vertical direction, and in some examples, the first and second side support sections 52, 54 of the link member 5 are made substantially perpendicular to the button body 21.

The following is an exemplary description of some applicable button 2 configurations:

in some implementations, as shown in fig. 13, the button 2 includes: the button comprises a button main body 21 and a cover body 22, wherein the button main body 21 is hinged to the shell 1, and the cover body 22 is buckled on the button main body 21 and is exposed in a button through hole 110 formed in the top wall of the shell 1; the first connection locations 201 and the second connection locations 202 are uniformly distributed on the button body 21.

The area of the button body 21 at the button via hole 110 may be designed to be smaller, and the area of the cover 22 at the button via hole 110 may be designed to be larger, so as to enlarge the pressing area, thereby achieving a more labor-saving pressing effect, and further facilitating the beautification of the appearance of the button 2.

In application, the button main body 21 is driven to synchronously rotate by pressing the cover body 22.

In some examples, as shown in fig. 13, the button body 21 includes: a button main body portion 211 and an ear plate portion 212, the upper end of the ear plate portion 212 being connected to the lower end of the button main body portion 211, a second connection position 202 being arranged at the bottom center position of the button main body portion 211; the lower end of the ear plate portion 212 is arranged with a first connection site 201.

The second connecting position 202 is arranged at the central position of the button main body part 211, the two first connecting positions 201 are arranged at the lug plate part 212 below the button main body part 211, the distance between the second connecting position 202 and the rotating piece 4 is larger, the elastic piece 6 can be designed to be longer, the stretching effect of the elastic piece 6 is improved, the distance between the first connecting position 201 and the rotating piece 4 is smaller, the connecting rod piece 5 can be designed to be shorter, the transmission effect of the connecting rod piece 5 is improved, and the transmission is more direct, smooth and efficient.

In addition, it can be appreciated that the elastic member 6 is farther from the rotation shaft 400 of the rotation member 4 with respect to the link member 5, which makes the telescopic stroke of the elastic member 6 larger than the rotation stroke of the link member 5 (accordingly, the latter stage of the rotation stroke of the rotation member 4 comes mainly from the elastic member 6), so that the length of the elastic member 6 is larger than the length of the link member 5, and it is also possible to adapt to this condition.

In some examples, as shown in fig. 13, the number of the ear plate portions 212 is two, the two ear plate portions 212 are respectively located at opposite sides of the button main body portion 211, an upper end of each ear plate portion 212 is connected to a lower end of a corresponding side of the button main body portion 211, and one first connection site 201 is disposed at a lower end of each ear plate portion 212.

It is of course also possible to design the ear plate 212 as a unitary structure, for example, the lower end of the ear plate 212 being a hollow shaft body, the cavity of which serves as the first connection point 201.

In some examples, as shown in fig. 13, the cover 22 includes a first side wall portion 221, a first pressing portion 222, a second pressing portion 223, and a second side wall portion 224 connected in sequence; the first pressing portion 222 and the second pressing portion 223 are disposed obliquely with respect to each other, and the first pressing portion 222 and the second pressing portion 223 are engaged with the button main body portion 211.

Illustratively, the top wall of the button body 211 includes two pressing portions inclined relative to each other, the first pressing portion 222 overlapping one of the pressing portions in a surface-to-surface contact manner, and the second pressing portion 223 overlapping the other pressing portion in a surface-to-surface contact manner, so that the pressing operation of the cover 22 is completely equivalent to the pressing operation of the button body 211.

The first side wall 221 is located below the first pressing portion 222 and connected to one side of the button main body 211; the second side wall portion 224 is located below the second pressing portion 223 and connected to the other side of the button main body portion 211. For example, the two side wall portions are connected by clamping, so as to realize the assembly of the cover 22 on the button main body 21.

In some examples, the first side wall portion 221 and the corresponding side on the button main body portion 211 are each designed in a flat plate shape, and the second side wall portion 224 and the corresponding side on the button main body portion 211 are each designed in an arc plate shape. As mentioned above, the push button 2 is balanced in position by the link member 5 at both the opening and closing positions, and a first stopper 101 and two second stoppers 102 (see fig. 14) are arranged inside the housing 1 in order to cancel out unbalance of the push button 2 by pulling the push button 2 by the stretched elastic member 6.

As can be seen from fig. 2, when the button 2 is at the closing position, the first stop 101 abuts against one end of the first pressing portion 222 away from the second pressing portion 223, so that the first pressing portion 222 is horizontally disposed in the button via hole 110, and the second pressing portion 223 is located outside the button via hole 110 and is in an upturned state.

As shown in fig. 14, when the button 2 is in the opening position, the second stop block 102 abuts against one side of the two ear plate portions 212 away from the second pressing portion 223, so that the second pressing portion 223 is horizontally disposed in the button via hole 110, and the first pressing portion 222 is located outside the button via hole 110 and is in an upturned state.

In some examples, as shown in fig. 1, the housing 1 includes: a face cover 11, a first side case 12, and a second side case 13; the first side shell 12 and the second side shell 13 are matched and butted to form a cavity with an upper opening; the face cover 11 is connected to the first side case 12 and the second side case 13 to close the upper opening; opposite sides of the button 2 are hinged to the first side case 12 and the second side case 13, respectively, and the face cover 11 has button holes 110 exposing the button 2.

With the above structure of the casing 1, as shown in fig. 2, the first stop 101 is connected to the cover 11 and located at one side of the inside of the button via hole 110, when the button 2 is at the closing position, the first pressing portion 222 is horizontally disposed in the button via hole 110, and the bottom wall of the end of the first pressing portion 222 is horizontally overlapped on the top wall of the first stop 101, so as to counteract the pulling force applied to the button 2 by the elastic member 6.

In combination with the above-described structure of the housing 1, as shown in fig. 14, two second stoppers 102 may be disposed, where the two second stoppers 102 are respectively connected to the first side case 12 and the second side case 13 and located at one side of the inside of the upper opening, and when the button 2 is in the opening position, the ear plate portion 212 rotates in the opening direction until the side wall thereof abuts against the side wall surface of the second stopper 102, so as to counteract the pulling force applied to the button 2 by the elastic member 6.

In some implementations, as shown in fig. 2, the elastic member 6 is a tension spring, a first end of the elastic member 6 is hooked on the second connection location 202 of the button 2, and a second end of the elastic member 6 is hooked on the third connection portion 43 of the rotating member 4.

For example, a support shaft is provided at the bottom of the button main body 211, an annular groove is provided in the middle of the support shaft as the second connection location 202, and the first end of the elastic member 6 is hooked on the annular groove-shaped second connection location 202 (see fig. 13) to achieve stable connection.

The third connecting portion 43 of the rotating member 4 is an ear plate structure protruding above the second end of the rotating body portion 40, and a through hole is formed thereon, so that the second end of the elastic member 6 is hooked in the through hole, and stable connection is achieved.

Based on the above, the supporting body 3 is used for supporting the rotating member 4 and allowing the rotating member 4 to rotate, and in some examples, the supporting body 3 has a limiting mechanism thereon, and the supporting body 3 is configured to allow the rotating member 4 to rotate in a vertical direction and limit the rotating member 4 in a horizontal direction by using the limiting mechanism.

As shown in fig. 15, the support body 3 includes a support body 30 and a support block 31 at a first end of the support body 30, the support block 31 being provided with an open groove 310 having a side opening facing the rotating body portion 40; the limiting mechanism comprises a first limiting rib 301, and the first limiting rib 301 is fixed in an opening groove 310.

As can be seen from fig. 16, a first limiting groove 4002 is provided in the middle of the first end of the rotating body 40, the first end of the rotating body 40 enters the open groove 310 through a side opening, and the bottom wall of the first end of the rotating body 40 is overlapped with the bottom wall of the open groove 310, and the first limiting rib 301 is located in the first limiting groove 4002. The rotating body portion 40 can be lapped on the supporting block 31 to rotate, and the first limiting rib 301 is matched with the first limiting groove 4002, so that the first end of the rotating member 4 can be limited in the horizontal direction, and can only rotate in the vertical direction and cannot be displaced in the horizontal direction.

Further, as shown in fig. 15, the limiting mechanism further includes a first stop block 302, where the first stop block 302 is connected to the top end of the supporting block 31; the first stop block 302 is adapted to stop against the top wall of the first end of the rotatable body portion 40 when the switch is in an off state (see fig. 16).

During the opening of the switch, the first end of the rotating body 40 rotates upwards, and when it rotates in place (i.e. the push button 2 is in the opening position), the first stop block 302 is used to stop against the top wall of the first end of the rotating body 40, preventing the rotating member 4 from rotating excessively.
