Some embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

First embodiment

Referring to fig. 1 and 2, the present embodiment discloses a switch, which includes a housing 10, a frame 20, a terminal assembly 50, a button assembly 60, a transition assembly and a swing assembly 70.

The housing 10 is primarily intended for housing the terminal assembly 50, the button assembly 60, the transition assembly and the swing assembly 70. The housing 10 includes a first portion 11 and a second portion 12 connected to each other, the first portion 11 and the second portion 12 each have a hollow, uncapped box shape, and the cross-sectional area of the first portion 11 is larger than that of the second portion 12, the first portion 11 has a first opening and a first wall 110 opposite to each other, the second portion 12 has a second opening and a second wall 120 opposite to each other, the portion of the second portion 12 having the second opening is integrally connected to the first wall 110 of the first portion 11, and the second opening penetrates into the inner cavity of the first portion 11, so that the inner cavity of the first portion 11 and the inner cavity of the second portion 12 are communicated.

When the swing link 71 is mounted on a wall, a desk or the like, the second portion 12 is sunk into the member, and the first portion 11 is exposed from the surface of the member. The frame 20 is sleeved outside the first part 11 of the shell 10, so that the attractive effect is achieved. A terminal assembly 50 is secured within the second portion 12 of the housing 10 for electrical supply line connection.

Referring to fig. 3, the transition assembly includes a pressing plate 30 and a transition piece 40, the pressing plate 30 is fixedly connected to the first portion 11 of the housing 10 by a buckle, and the pressing plate 30 has a pressing portion extending into the second portion 12, and the pressing portion presses the terminal assembly 50.

The transition piece 40 is rotatably connected to the pressing plate 30 and is capable of swinging between a first dialing position and a second dialing position along a first rotation direction a and a second rotation direction B relative to the pressing plate 30, wherein a direction from the first dialing position to the second dialing position is the first rotation direction a, a direction from the second dialing position to the first dialing position is the second rotation direction B, and the first rotation direction a and the second rotation direction B are opposite.

Specifically, the transition piece 40 includes a button connection portion 41 and a swing link connection portion 42 that are vertically connected, a middle portion of the button connection portion 41 is rotatably connected to the pressing plate 30, and the swing link connection portion 42 passes through the pressing plate 30 to extend into the inner cavity of the second portion 12 of the housing 10, so that the swing link connection portion 42 is rotatably fitted with respect to the pressing plate 30.

The swing link connection portion 42 has a transition cavity 420, the transition cavity 420 penetrates to one end of the swing link connection portion 42 facing the second wall 120 of the second portion 12, a swing spring 422 and a push rod 421 are disposed in the transition cavity 420, and the swing spring 422 is sleeved outside the push rod 421.

The swinging assembly 70 may be a swinging rod type or a tilting type, for example, the swinging assembly 70 includes a swinging rod 71 and a movable contact 72 disposed on the swinging rod 71, one end of the swinging rod 71 abuts against the second wall 120 of the second portion 12 of the housing 10, and the other end extends into the transition cavity 420 of the swinging rod connecting portion 42 to be inserted into the swinging spring 422.

The button assembly 60 is mounted on the button connection portion 41 of the transition piece 40 through a buckle, so, when the switch is turned on and off, the button assembly 60 is pressed to drive the transition piece 40 to swing in a first rotation direction A or a second rotation direction B relative to the pressing plate 30, then the swinging spring 422 in the transition cavity 420 is bent and deformed, the swinging rod 71 is further swung, and the movable contact 72 on the swinging rod 71 is contacted with or separated from the fixed contact 51 on the terminal assembly 50, so that the switch is turned on and off.

In order to eliminate design and process tolerance in the prior art, so as to ensure that the movable contact 72 on the swinging component is fully contacted with the stationary contact 51 on the terminal component 50, avoid ablation phenomenon caused by insufficient contact, and ensure normal power on and performance, the switch adopts an over-travel design, that is, the size of the transitional inner cavity of the swing link connection part 42 of the transition piece 40 is made large, so that a reserved gap is reserved between the swinging spring 422 and the inner wall of the transitional cavity 420, so that the spring is allowed to perform expected bending deformation, and a certain contact pressure between the movable contact 72 and the stationary contact 51 is ensured.

However, since the button assembly 60 is directly and fixedly connected to the button connection portion 41 of the transition piece 40, the swinging angles of the button assembly 60 and the transition piece 40 are the same, so that when the user presses the button assembly 60, because a larger idle stroke exists in the reserved gap, a virtual position exists between the button assembly 60 and the housing 10, the button assembly 60 floats, the button assembly 60 cannot be completely reset after being dialed, uneven positions exist for a plurality of buttons, the standard requirements of enterprises are not met, the overall appearance of a switch product is not influenced, a larger gap exists between the button assembly 60 and the first portion 11 of the housing 10, and in the process of dialing the button assembly 60 by the user, as an action point of the swinging spring 422 to the transition piece 40 through the ejector rod 421 is in the middle, the swinging spring 422 does not have an action force for swinging the transition piece 40, so that the user has a clamping phenomenon when dialing the button assembly 60, and the user experience is seriously influenced.

In order to ameliorate the above-described drawbacks, therefore, in the present embodiment, the transition assembly further includes an elastic member 80, and in combination with fig. 3 and 4, the elastic member 80 is disposed between the pressing plate 30 and the button connecting portion 41 of the transition member 40 for causing the transition member 40 to have a tendency to swing in the first rotation direction a or the second rotation direction B, that is, the elastic member 80 can assist the transition member 40 to swing to the second dialing position when the transition member 40 swings in the first rotation direction a, and the elastic member 80 can assist the transition member 40 to swing to the first dialing position when the transition member swings in the second rotation direction B.

In this way, when the user dials the button assembly 60 to drive the transition piece 40 to swing along the first rotation direction a or the second rotation direction B, the transition piece 40 can be pushed to swing to the second dialing position along the first rotation direction a or swing to the first dialing position along the second rotation direction B by the elastic action of the elastic piece 80 between the pressing plate 30 and the transition piece 40, so that the button assembly 60 fixed on the transition piece 40 can be smoothly dialed in place, the clamping phenomenon is eliminated, and the transition piece 40 can accurately reach the first dialing position or the second dialing position by the elastic action of the elastic piece 80 on the transition piece 40, so that the virtual position between the button assembly 60 and the casing 10 is eliminated, the button is prevented from floating, the multi-position buttons can not have height differences, and the appearance quality of the switch product is ensured.

In this embodiment, the elastic member 80 is specifically disposed between one end of the button connecting portion 41 and the pressing plate 30, so that the force arm between the acting point of the elastic member 80 on the button connecting portion 41 and the rotation axis of the button connecting portion 41 is larger, and thus under the condition that the elastic acting force of the elastic member 80 is fixed, the bending moment of the button connecting portion 41 received by the elastic member 80 is larger, the button connecting portion is easier to swing, and is easier to abut against the housing 10, and the virtual position is eliminated.

Specifically, referring to fig. 5, the platen 30 is provided with a long groove 31 and a through hole 32, the depth direction of the long groove 31 is the same as the thickness direction of the platen 30, and the through hole 32 penetrates the middle of the groove bottom of the long groove 31.

The middle part on the side wall of the long groove 31 in the groove width direction is rotatably connected with the middle part of the button connecting part 41, the elastic piece 80 is arranged between the end part of the button connecting part 41 and the end wall of the long groove 31 in the groove length direction, the swinging rod connecting part 42 passes through the perforation 32 to extend into the second part 12 of the shell 10 so as to allow the swinging rod 71 to extend into the transition cavity 420, and thus the long groove 31 is arranged on the pressing plate 30 to accommodate the button connecting part 41, thereby reducing the overall height of the button connecting part 41 and the pressing plate 30, further reducing the overall height of a switch product, and enabling the overall structure to be more compact.

The pressing plate 30 is provided with a connecting lug 33 on each side of the long groove 31 in the width direction, and the button connecting part 41 is rotatably connected to the connecting lug 33 by a hinge shaft.

The end of the button connection portion 41 and/or the end wall of the long groove 31 of the pressing plate 30 are provided with attachment portions, and the elastic member 80 is a tubular spring or the like, and the end of the elastic member 80 is connected to the attachment portions.

The end of the elastic member 80 is abutted against the mounting portion, so that a raised rib portion is provided on the mounting portion, and the elastic member 80 is sleeved outside the rib portion, so that the elastic member 80 is prevented from falling off.

Specifically, referring to fig. 6, the mounting portion connected to the end of the button connection portion 41 is a transitional mounting portion 411, the transitional mounting portion 411 and the button connection portion 41 are in an integral structure, the rib portion provided on the transitional mounting portion 411 is a transitional rib portion 410, the transitional rib portion 410 is formed by criss-cross rib plates, and one end of the elastic member 80 abuts against the transitional mounting portion 411 and is sleeved outside the transitional rib portion 410.

The mounting portion provided on the end wall of the long groove 31 of the pressing plate 30 is a pressing plate mounting portion 34, the pressing plate mounting portion 34 corresponds to the end of the button connecting portion 41, the rib portion on the pressing plate mounting portion 34 is a fixing rib portion 342, and the other end of the elastic member 80 abuts against the pressing plate mounting portion 34 and is sleeved outside the fixing rib portion 342.

Specifically, with continued reference to fig. 4 and 5, the platen mounting portion 34 is integrally connected to the end wall of the long slot 31 so as to be fixed relative to the platen 30, a mounting hole 340 is provided on a surface of the platen mounting portion 34 facing the button connecting portion 41, a hole length direction of the mounting hole 340 is the same as a slot length direction of the long slot 31, the mounting hole 340 is a blind hole, the elastic member 80 extends into the mounting hole 340, thereby realizing mounting of the elastic member 80, and the fixing rib portion 342 is provided at a hole bottom of the mounting hole 340.

Of course, since one end of the elastic member 80 is sleeved on the transition rib portion 410, when the button connecting portion 41 swings, one end of the elastic member 80 swings relative to the other end of the elastic member, if the inner diameter of the mounting hole 340 is only slightly larger than the outer diameter of the elastic member 80, the portion of the elastic member 80 exposed out of the mounting hole 340 bends along with the swinging of the button connecting portion 41, so that the direction of the pushing force applied by the elastic member 80 to the button connecting portion 41 changes and the force becomes smaller, so that in order to prevent the elastic member 80 from bending at the portion of the aperture of the mounting hole 340 as much as possible, the aperture of the mounting hole 340 needs to be made larger than the outer diameter of the elastic member 80, for example, the inner diameter of the mounting hole 340 is gradually reduced along the direction from the aperture to the bottom of the mounting hole, so that the inner wall of the mounting hole 340 and the elastic member 80 can have a sufficient gap, so that the elastic force applied by the elastic member 80 to the transition member 40 can swing along with the swinging of the button connecting portion 41, so that the direction of the elastic member 80 can be correspondingly changed, and the transition member 40 is prevented from bending along with the first rotation direction a or the second rotation direction B of the elastic member 80.

In addition, in order to avoid excessive bending of the two end positions of the elastic member 80, the two rib parts, namely, the transition rib part 410 and the fixing rib part 342, are respectively provided with a reducing structure, the two opposite ends of the rib part in the protruding direction thereof are respectively provided with a first end and a second end, the outer diameter of the first end is larger than that of the second end, the first end is connected with the mounting part, namely, the first end of the transition rib part 410 is connected with the transition mounting part 411, the first end of the fixing rib part 342 is connected with the pressing plate mounting part 34, namely, the outer diameter of the transition rib part 410 gradually decreases along the end, which is connected with the transition member 40, to the end far from the transition member 40, and the outer diameter of the fixing rib part 342 also gradually decreases along the hole bottom to the hole opening direction of the mounting hole 340.

With continued reference to fig. 4, the slope tan α of the inclined surface 3420 of the fixing rib 342 connected between the first end and the second end with respect to the protruding direction of the fixing rib 342 is greater than the slope tan β of the axis of the elastic member 80 with respect to the protruding direction of the fixing rib 342, so that the elastic member 80 can change its direction conveniently.

If the transition piece 40 is in the first dialing position as shown in fig. 3 and 4, the elastic piece 80 applies a force F to the button connection 41 ₁ Is oriented obliquely upward and leftward as viewed in FIG. 7, at this time, the push button connection portion 41 receives an upward component force F _{Divide 1} ＝F ₁ ·Sinθ ₁ The component F ₁ The button connecting portion 41 is caused to have a tendency to continue to swing in the second rotation direction B, thereby driving the button assembly 60 to continue to press toward the housing 10 toward the lower left, eliminating the problem of the left virtual position of the button assembly 60. When the user dials the button assembly 60 to drive the transition piece 40 to swing to the second dialing position along the first rotation direction a, the elastic piece 80 applies the force F to the button connection portion 41 ₂ Is oriented obliquely downward and leftward as viewed in FIG. 8, at which the push button connection portion 41 receives a downward component F _{Divide 2} ＝F ₂ ·Sinθ ₂ The component F ₂ The button connecting portion 41 is caused to continuously swing along the first rotation direction a, so that the button assembly 60 is driven to continuously press towards the casing 10 towards the right downward direction, and the problem of the virtual position on the right side of the button assembly 60 is eliminated.

It should be noted that, when the transition piece 40 is located at the center position, the vertical distances from the two ends of the button connection portion 41 to the reference surface are respectively equal, and the axis of the elastic member 80 is equal to the reference surfaceThe test surface is parallel, i.e. the axis of the elastic member 80 is the same as the length direction of the long slot 31, and the center of the transition rib portion 410 and the center of the mounting hole 340 are on the same horizontal line, so that the acting force F of the elastic member 80 on the button connecting portion 41 can be applied when the button assembly 60 is located at the first dialing position ₁ And F ₂ The size and the direction of the button connecting part 41 are the same as much as possible, so that the acting force of the elastic piece 80 on the button connecting part 41 is in the horizontal direction when the button connecting part 41 passes through the center position, and the clamping phenomenon is better eliminated. Moreover, when the button connecting portion 41 is located at the center position, the axis of the elastic member 80 and the rotation axis of the button connecting portion 41 are located at the same level, that is, the axes are located at the same plane, so that when the button connecting portion 41 continues to swing towards the first dialing position or the second dialing position after passing through the center position, the axis of the elastic member 80 also swings along with the swinging of the transition member 40, thereby exerting a force on the transition member 40, so that the power-assisted transition member 40 swings to the first dialing position along the first rotation direction a or the power-assisted transition member 40 swings to the second dialing position along the second rotation direction B, and no virtual position is generated between the button assembly 60 and the housing 10 after the button assembly 60 is dialed to any direction to stop moving.

In addition, since the elastic member 80 swings with the swinging of the transition member 40, the included angle of the axis of the elastic member 80 with respect to the reference surface may vary within a certain range, that is, the same angle as the included angle β of fig. 4, for example, the maximum included angle formed by the axis of the elastic member 80 and the reference surface is 10 to 80 °, preferably 20 to 80 °, and particularly 30 °, 40 ° or 45 ° or the like may be selected.

Of course, in the embodiment shown in fig. 3, the elastic member 80 is provided only between one end of the button connecting portion 41 and one end wall of the elongated slot 31, and in other embodiments, the elastic member 80 may be provided between both ends of the button connecting portion 41 and both end walls of the elongated slot 31, that is, both ends of the button connecting portion 41 are provided with the protruding transition rib portions 410, and the platen mounting portions 34 are integrally connected to both end walls of the elongated slot 31.
