In the description of the present application, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present application and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present application.

Referring to fig. 1 to 4, and fig. 8, the present application provides a push-button switch including:

the base 10, the base 10 is used for connecting with the bottom box;

The key body 20, one of the key body 20 and the base 10 comprises a first clamping part 21, the other comprises a second clamping part 11, and the second clamping part 11 and the first clamping part 21 are pivotally clamped together so that the key body 20 can pivot around a first axis L1 relative to the base 10;

Wherein, the first clamping portion 21 includes a clamping groove 211, a notch of the clamping groove 211 faces the second clamping portion 11, the second clamping portion 11 includes a clamping body 111, and when the second clamping portion 11 and the first clamping portion 21 are clamped together, the clamping body 111 is accommodated in the clamping groove 211;

The depth dimension of the clamping groove 211 is greater than the length dimension of the clamping body 111, so that after the base 10 is deformed to cause the first clamping portion 21 to move in a direction away from the key body 20, the clamping body 111 can still be accommodated in the clamping groove 211.

Here, the depth dimension of the engaging groove 211 refers to the distance between the groove bottom and the notch of the engaging groove 211, and the length dimension of the engaging body 111 refers to the length of the engaging body 111 in the distribution direction of the groove bottom and the notch of the engaging groove 211 in a state where the engaging body 111 extends into the engaging groove 211.

In addition, the bottom box is installed on the installation wall body and is used for installing the key switch. That is, the push switch is directly connected with the bottom box, and the bottom box is directly connected with the installation wall. The mounting wall may be reinforced concrete, composite, or wooden, as the application is not limited.

Based on this technical scheme, the depth of the clamping groove 211 can allow the base 10 to deform, so long as the distance that the first clamping portion 21 moves towards the direction away from the key body 20 due to deformation is within the range allowed by the depth dimension of the clamping groove 211, the clamping body 111 can be ensured to be still located in the clamping groove 211, so that the first clamping portion 21 and the second clamping portion 11 can still be stably clamped together, that is, the key body 20 is stably and pivotally connected to the base 10, and shaking of the key body 20 is avoided.

Specifically, referring to fig. 2, in one possible embodiment, the first clamping portion 21 further includes a stop protrusion 212, the stop protrusion 212 is located on an inner surface of the clamping groove 211, an inner diameter of the clamping groove 211 at the stop protrusion 212 is smaller than an outer diameter of the clamping body 111 to prevent the clamping body 111 from being separated from the clamping groove 211, and a distance between the stop protrusion 212 and a bottom of the clamping groove 211 is greater than a length dimension of the clamping body 111. In this way, the blocking protrusion 212 can be used to limit the blocking body 111 in the blocking slot 211, the blocking body 111 can pivot in the blocking slot 211, and when the base 10 is deformed to cause the first blocking portion 21 to be far away from the key body 20, the blocking protrusion 212 can move towards the blocking protrusion 212 in the blocking slot 211.

In one example, referring to fig. 2, the clamping groove 211 includes a first arc surface 2111 and two side surfaces 2112, the two side surfaces 2112 being parallel and spaced apart on opposite sides of the first arc surface 2111, the two side surfaces 2112 being tangential to the first arc surface 2111; the clamping body 111 includes a second arcuate surface 1110, the second arcuate surface 1110 faces the first arcuate surface 2111, and the curvature of the second arcuate surface 1110 and the first arcuate surface 2111 are the same. In this way, the second arc surface 1110 of the clamping body 111 can be in shape-matched contact with the first arc surface 2111 of the clamping groove 211, so that the space in the clamping groove 211 can be fully utilized, and the moving distance of the clamping body 111 in the clamping groove 211 can be increased, so as to better adapt to the deformation of the base 10. Further, since the two side surfaces 2112 are parallel, the engaging body 111 can smoothly move toward the notch of the engaging groove 211, and the rotational resistance of the engaging body 111 at any position within the engaging groove 211 is the same.

It should be appreciated that the curvature of the second arcuate surface 1110 and the first arcuate surface 2111 are the same, including both being identical or substantially identical. This also falls within approximately the same range, as there is a slight difference in the degree of curvature of the two due to the need for assembly. For example, the curvature of the second arcuate surface 1110 on the clamping body 111 may be slightly less than the curvature of the first arcuate surface 2111 on the clamping slot 211.

In one example, referring to fig. 3 and 5, the clamping body 111 is a cylinder with an axis parallel to the first axis L1. In this way, the key body 20 can be made to pivot stably about the first axis L1.

In one possible embodiment, referring to fig. 3 and 5, the second clamping portion 11 further includes a blocking body 112, where the blocking body 112 is connected to the clamping body 111 and is located on a side of the clamping body 111 away from the first clamping portion 21, and when the clamping body 111 is located in the clamping groove 211, a portion of the blocking body 112 extends out of the clamping groove 211 to limit the pivot angle of the key body 20. Thus, based on this technical solution, the rotation range of the clamping body 111 can be controlled more conveniently, thereby controlling the rotation range of the key body 20.

In one possible embodiment, referring to fig. 3 and 4, the base 10 further includes a first through hole 12, the clamping body 111 is located in the first through hole 12, opposite ends of the clamping body 111 in the axial direction thereof are respectively connected with the inner wall of the first through hole 12, the first clamping portion 21 is inserted into the first through hole 12, and the clamping body 111 is inserted into the clamping groove 211. In this way, the first engaging portion 21 can be hidden in the first through hole 12, not only having a beautifying effect on the appearance of the key switch, but also reducing the external dimension of the key switch in the axial direction of the first through hole 12. Here, the axial direction of the engaging body 111 is substantially perpendicular to the inner wall surface of the first through hole 12 or substantially perpendicular to the axial direction of the second through hole 12.

In a possible embodiment, referring to fig. 3 and 4, the base 10 further includes a first connection portion 13, and the first connection portion 13 is configured to connect with the bottom case. In this way, the base 10 may be fixed on the bottom case, and then the key body 20 and the base 10 are pivotally connected together through the first clamping portion 21 and the second clamping portion 11.

In one example, referring to fig. 3 and 4, the first connection part 13 includes a second through hole 131 provided on the base 10, and an axial direction of the second through hole 131 and a depth direction of the bottom case are the same. Here, the depth direction of the bottom case means a direction substantially perpendicular to the installation wall surface, and the bottom case is fixed to the installation wall surface in a direction substantially perpendicular to the installation wall surface. In actual use, the fastener may be connected to the bottom case after passing through the second through hole 131, so that the base 10 may be fixed to the bottom case. In this case, the base 10 is deformed toward the switch fixing wall, so that the first clamping portion 21 and the second clamping portion 11 are separated, but the clamping body 111 can still be accommodated in the clamping groove 211 due to the large depth dimension of the clamping groove 211, and the key body 20 can still be stably clamped with the base 10. Wherein the axial direction of the second through hole 131 is the same as the axial direction of the first through hole 12.

In one example, the first connection portion 13 includes two second through holes 131. In this way, the base 10 can be firmly fixed to the bottom case through the two second through holes 131, and the shape of the portion of the base 10 located between the two second through holes 131 is stabilized.

In one example, the number of the second clamping portions 11 is two, and the two second through holes 131 are located between the two second clamping portions 11. In the case that the base 10 is firmly fixed on the bottom case, the two second through holes 131 are located between the two second clamping portions 11, which is beneficial to ensuring that the first clamping portion 21 and the second clamping portion 11 are stably clamped together. Wherein, the two first clamping parts 21 and the two second through holes 131 are distributed at intervals along a straight line.

In one possible implementation, referring to fig. 6 and 7, the key body 20 further includes a first driving leg 22 and a second driving leg 23, and the key body 20 includes an open position and a closed position in a path pivoting about the first axis L1, the first driving leg 22 and the second driving leg 23 being spaced apart on both sides of the first axis L1; the push-button switch further comprises a movable contact piece 40 and a swinging piece 30, wherein the movable contact piece 40 is pivotally connected with the base 10, and the movable contact piece 40 comprises a closed position and an open position on a pivot path; the swinging member 30 includes a main body 33, a first bracket 31 and a second bracket 32, the first bracket 31 and the second bracket 32 are connected at opposite sides of the main body 33, one end of the main body 33 is pivotally connected with the second connecting portion 13 around the second axis L2, the other end of the main body 33 is connected with the movable contact piece 40, the main body 33 is located between the first driving leg 22 and the second driving leg 23, the first driving leg 22 is connected with the first bracket 31, and the second driving leg 23 is connected with the second bracket 32; during the movement of the key body 20 from the closed position to the open position, at least one of the first driving leg 22 and the second driving leg 23 drives the swinging member 30 to pivot about the second axis L2, and the swinging member 30 can drive the movable contact 40 to move from the open position to the closed position during the pivoting; during the movement of the key body 20 from the open position to the closed position, at least one of the first driving leg 22 and the second driving leg 23 drives the swinging member 30 to pivot about the second axis L2, and the swinging member 30 can drive the movable contact 40 to move from the closed position to the open position during the pivoting.

Based on the above technical solution, when the key body 20 pivots relative to the base 10, the first driving leg 22 and the second driving leg 23 can drive the main body 33 to pivot or swing around the second axis L2, and then the main body 33 can drive the movable contact 40 to pivot relative to the base 10, so as to achieve the purpose of opening or closing.

It should be clear that, when the key body 20 is in the closed position (i.e. the OFF position), the movable contact 40 is in the open position, and at this time, the movable contact 40 is not connected to the corresponding conductive circuit.

When the key body 20 is located at the open position (i.e. ON position), the movable contact 40 is located at the closed position, and at this time, the movable contact 40 is connected to the corresponding conductive circuit.

In one example, the first drive leg 22 and the first bracket 31 may be snapped together and the second drive leg 23 and the second bracket 32 may be snapped together.

In another example, the first drive leg 22 and the first bracket 31 may be in an abutting relationship and the second drive leg 23 and the second bracket 32 may be in an abutting relationship. For example, the first driving leg 22 corresponds to the first bracket 31, the first driving leg 22 being pressed against the first bracket 31 to pivot the main body 33 about the second axis L2 during movement of the key body 20 toward the open position, and the second driving leg 23 being pressed against the second bracket 32 to pivot the main body 33 about the second axis L2 during movement of the key body 20 toward the closed position.

In addition, referring to fig. 6 and 7, the push button switch further includes an elastic member 50 and a slider 60, a blind hole is formed in the main body 33, the elastic member 50 is located in the blind hole, both ends of the elastic member are respectively connected to the main body 33 and the slider 60, and the slider 60 can slide along an axial direction of the blind hole. When the main body 33 rotates around the second axis L2, the sliding member 60 rotates around the second axis L2 along with the main body 33, and the elastic member 50 always applies an elastic force to the sliding member 60 toward the movable contact 40, so as to ensure that the movable contact 40 can be driven to rotate by the sliding member 60.
