Description

Technical Field

[0001] This application relates to the technical field of electrical switches, and in particular, to a push-button switch. Background Art

[0002] A push-button switch is a commonly used switching device. The push-button switch includes a button, a base, and an internal circuit structure. The internal circuit structure is installed in the base, and the button is pivotally connected to the base so as to be able to reciprocally rotate between a first position and a second position relative to the base. When the button moves to the first position or the second position, it can conduct or disconnect the circuit that triggers the internal circuit structure, thereby realizing the switching function. For example, when the button moves to the open position, the internal circuit of the switch is turned on, so that the target electrical device controlled by the switch is in the powered-on state; when the button moves to the closed position, the internal circuit of the switch is turned off, so that the target electrical device controlled by the switch is in the powered-off state.

[0003] In the related art, the base includes a main body and a mounting frame. The mounting frame contacts and is fixedly connected to the mounting wall. The button is pivotally connected to the main body but is surrounded by the mounting frame. During installation, first connect the mounting frame to the mounting wall, and then pivotally connect the button and the main body. Since the button is surrounded by the mounting frame, this structure makes it inconvenient to connect the button and the main body. Summary of the Utility Model

[0004] To solve the above technical problems, an embodiment of this application provides a push-button switch, which can solve the above technical problems.

[0005] This application provides a push-button switch. The push-button switch includes a base and a button. The base is used to connect to a mounting wall. The button includes a connecting portion, and the connecting portion and the base are pivotally connected around a preset axis. The button reciprocally rotates around the preset axis relative to the base between a first position and a second position to realize the switching function. Wherein, the button and the base are distributed along a preset direction, the preset direction is perpendicular to a virtual plane, the virtual plane is parallel to the preset axis, and the orthographic projection of the base on the virtual plane falls within the orthographic projection range of the button when it is in the first position on the virtual plane.

[0006] Based on the above push-button switch, since the orthographic projection of the base on the virtual plane falls within the orthographic projection range of the button when it is in the first position on the virtual plane, it can be known that in the direction perpendicular to the preset direction, the size of the button is larger than that of the base, and the button is located outside the base and is not surrounded by the base. Moreover, since the button can pivotally connect between the first position and the second position relative to the base, there must be a gap between the button and the base. Then, when the button is installed on the base, it can be observed through this gap. Also, because the button is located outside the base and is not surrounded by the base, it is convenient to apply an external force to the button, thus facilitating the installation of the button on the base. Additionally, when the push-button switch is fixed to the installation wall, the button can block the base. The base can be fixedly connected to the installation wall, and the button is located outside the installation wall and can cover the base and the groove. Moreover, when the user looks at the installation wall, only the button can be seen, thus presenting an effect that the button floats on the installation wall, enriching the user's experience.

[0007] Optionally, the push-button switch includes a first clamping structure, and the base and the button are clamped through the first clamping structure. In this way, the base and the button can be connected together by clamping, which is convenient for installing the button on the base.

[0008] Optionally, the connecting portion includes ear plates. The number of the ear plates is two and they are distributed along the extending direction of the preset axis. The first clamping structure includes a circular hole and a first opening provided on the ear plate, and the first opening is communicated with the circular hole. The first clamping structure further includes a rotating shaft provided on the base. The rotating shaft is a cylinder, and the outer diameter of the rotating shaft is larger than the inner diameter of the first opening. The ear plate can undergo elastic deformation to expand the inner diameter of the first opening so that the rotating shaft can be inserted into the circular hole through the first opening. Moreover, the axis of the circular hole is parallel to the preset axis, and the axis of the rotating shaft coincides with the preset axis. In this way, it is convenient to insert the rotating shaft into the circular hole by using the elastic deformation of the ear plate to achieve the pivotal connection between the connecting portion of the button and the base.

[0009] Optionally, the base includes a base body and a bracket. The bracket includes a cylinder and a flange. The cylinder is sleeved outside the base body and is connected to the base body. The flange is connected to one end of the cylinder close to the button. A connecting hole is provided on the flange, and the connecting hole is used for connecting with the installation wall. In this way, the base can be conveniently fixed to the installation wall through the connecting hole, and the flange can be made to fit with the installation wall to stably fix the base to the installation wall.

[0010] Optionally, the push-button switch includes a second clamping structure and a third clamping structure, both of which are disposed between the base and the bracket to connect the base and the bracket; the second clamping structure and the third clamping structure jointly restrict the bracket from moving away from the bracket in a preset direction. In this way, through the restriction of the two clamping structures, the bracket and the base can be stably connected together.

[0011] Optionally, the second clamping structure includes a second opening, a tongue plate, and a first protrusion provided on the tongue plate; the second opening is provided at one end of the cylinder body away from the flange, and the opening direction of the second opening faces away from the button; the tongue plate is provided on the base, and one side of the first protrusion away from the flange has an inclined surface, and there is an acute angle between the inclined surface and the preset direction; the cylinder body surrounds the tongue plate, and the first protrusion is inserted into the second opening. In this way, by inserting the first protrusion into the second opening, the base can be prevented from moving away from the bracket along the preset direction and along the direction towards the second opening.

[0012] Optionally, the third clamping structure includes a third opening and a second protrusion, the second protrusion is provided on the outer surface of the base, the third opening is provided at one end of the cylinder body close to the flange and penetrates the flange, and the second protrusion is inserted into the third opening. In this way, by inserting the second protrusion into the second opening, the base can be prevented from moving away from the bracket along the preset direction and along the direction towards the third opening.

[0013] Optionally, the bracket further includes a first surrounding member and a second surrounding member, the first surrounding member is connected between the flange and the second surrounding member, the second surrounding member surrounds the first surrounding member, and the first surrounding member surrounds the flange; the distance between the second surrounding member and the flange in the preset direction is equal to the width dimension of the first surrounding member in the preset direction. In this way, the user can conveniently apply an external force to the second surrounding member during installation, so as to conveniently adjust the position of the base on the installation wall.

[0014] Optionally, the button includes a convex plate, the number of the convex plates is multiple and they are connected end to end in sequence to form a ring-shaped protrusion, and the ring-shaped protrusion surrounds the connecting portion. In this way, the ring-shaped protrusion can strengthen the structural strength of the button, and when looking at the push-button switch from a direction parallel to the virtual plane, the ring-shaped protrusion can cover the connecting portion, thereby helping to improve the aesthetic effect and the floating effect.

[0015] Optionally, the push-button switch further includes an elastic member disposed on the base; during the process of the button pivoting from the first position to the second position, the elastic member is pressed against the base by the button and compressed, and the compressed energy released by the elastic member can drive the button to pivot from the second position to the first position. In this way, the automatic rebound of the button can be realized by using the elastic member.

[0016] Optionally, the push-button switch further includes a hook and a stop portion, one of the hook and the stop portion is disposed on the base, and the other is disposed on the inner surface of the button; when the button is in the first position, the elastic member applies a force to the button along a preset direction and away from the base, and the hook is pressed against the stop portion under the action of this force; during the process of the button moving from the first position towards the second position, the hook moves away from the stop portion. In this way, when no external force acts on the button, the button can be jointly acted on by the elastic member, the hook and the stop portion to remain in the first position.

[0017] Optionally, the base includes a receiving hole, the stop portion is disposed in the receiving hole, and the hook extends into the receiving hole to be limited by the stop portion. In this way, the gap between the button and the base in the preset direction when the button is in the first position can be reduced, and the floating effect can be improved.

[0018] Optionally, the button includes a pressing protrusion disposed on the inner surface, and the pressing protrusion is used to press the elastic member. In this way, by providing the pressing protrusion, the length dimension of the elastic member in the preset direction can be reduced, and the probability that the elastic member is distorted and thus difficult to recover its deformation can be reduced.

In this way, the cover shell can conduct the acting force between the button and the elastic member, and can reduce the probability that the elastic member is distorted and thus difficult to recover its deformation.

[0030] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0031] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application.

[0032] Refer to Figures 1 to 3, this application provides a push-button switch 1, which includes a base 10 and a button 20. Among them, the base 10 is used to connect to the installation wall, and the button 20 includes a connecting portion 21, and the connecting portion 21 and the base 10 are pivotally connected around a preset axis R. In this way, the button 20 reciprocally rotates around the preset axis R relative to the base 10 between a first position and a second position to achieve the switch function. Among them, the button 20 and the base 10 are distributed along a preset direction X, the preset direction X is perpendicular to a virtual plane Y, and this virtual plane Y is parallel to the preset axis R. The orthographic projection of the base 10 on the virtual plane Y falls within the range of the orthographic projection of the button 20 on the virtual plane Y when the button 20 is in the first position. In other words, in any direction perpendicular to the preset direction X, the width dimension of the button 20 is greater than the width dimension of the base 10. Therefore, when looking from the direction of the button 20 towards the base 10, the base 10 can be covered by the button 20.

[0033] Obviously, based on the above technical solution, since the orthographic projection of the base 10 on the virtual plane Y falls within the range of the orthographic projection of the button 20 on the virtual plane Y when the button 20 is in the first position, it can be known that in the direction perpendicular to the preset direction X, the size of the button 20 is greater than the size of the base 10, and the button 20 is located outside the base 10 and is not surrounded by the base 10. And, since the button 20 can be pivotally connected between the first position and the second position relative to the base, there must be a gap between the button 20 and the base 10. Then, when the button 20 is installed on the base 10, it can be observed through this gap. Also, since the button 20 is located outside the base 10 and is not surrounded by the base 10, it is convenient to apply an external force to the button, thus facilitating the installation of the button on the base. In addition, when the push-button switch is fixed on the installation wall, the base can be fixedly connected to the installation wall, and the button is located outside the installation wall and can cover the base and the groove. Moreover, when the user looks at the installation wall, the button 20 can block the base 10, thus presenting an effect that the button floats on the installation wall, enriching the user's experience.

[0034] Among them, the installation wall can be made of reinforced concrete, or can be made of composite materials, or can be made of wood, which is not limited in this application.

[0035] To facilitate the installation of the button 20 on the base 10, the push-button switch 1 includes a first clamping structure, and the base 10 and the button 20 are clamped through the first clamping structure.

[0036] In one embodiment, refer to Figure 3 and Figure 4The connecting portion 21 includes two ear plates 211, which are distributed along the extension direction of the preset axis R. The first clamping structure includes a circular hole 212 and a first opening provided on the ear plate 211, and the first opening is connected to the circular hole 212. The first clamping structure also includes a rotating shaft 14 provided on the base 10. The rotating shaft 14 is a cylinder, and the outer diameter of the rotating shaft 14 is larger than the inner diameter of the first opening. The ear plate 211 can undergo elastic deformation to expand the inner diameter of the first opening so that the rotating shaft 14 can be inserted into the circular hole 212 through the first opening. In addition, the axis of the circular hole 212 is parallel to the preset axis R, and the axis of the rotating shaft 14 coincides with the preset axis R. In this way, with the first opening aligned with the rotating shaft 14, an external force can be applied to the button 20 along the predetermined direction X. As the rotating shaft 14 presses against the lugs 211 on either side of the first opening, the lugs 211 undergo slight elastic deformation, thereby expanding the first opening, thereby allowing the rotating shaft 14 to enter the circular hole 212 from the first opening. After the rotating shaft 14 enters the circular hole 212 from the first opening, the lugs 211 recover their deformation, and the first opening shrinks, thereby preventing the lugs 211 from detaching from the rotating shaft 14. This facilitates the coupling portion 21 and the base 10 to be snapped together, achieving a pivotal connection between the two.

[0037] In one possible embodiment, reference Figure 3 and Figure 4 The base 10 includes a base 11 and a bracket 12. The bracket 12 includes a cylinder 121 and a flange 122. The cylinder 121 is sleeved outside the base 11 and connected to the base 11. The flange 122 is connected to the end of the cylinder 121 near the button 20. A connecting hole 1220 is provided on the flange 122, and the connecting hole 1220 is used to connect to the installation wall. In this way, when the base 10 is fixed to the installation wall, the preset direction X is roughly perpendicular to the wall, so the base 10 can be conveniently fixed to the installation wall through the connecting hole 1220, and the flange 122 and the installation wall can also be fit together to enable the base 10 to be stably fixed to the installation wall. Specifically, the fastener can be connected to the installation wall after passing through the connecting hole 1220. The fastener can be a screw, a bolt or an expansion nail.

[0038] In one example, the connection portion 21 of the button 20 may be pivotally connected to the base 11 around a preset axis R. For example, the rotation shaft 14 is disposed on the base 11 , and the ear plate 211 is pivotally connected to the rotation shaft 14 .

[0039] Among them, the cylinder body 121 and the base body 11 can be connected in a snap - fit manner. For example, in one embodiment, the push - button switch 1 further includes a second snap - fit structure and a third snap - fit structure. Both the second snap - fit structure and the third snap - fit structure are disposed between the base body 11 and the bracket 12 to connect the base body 11 and the bracket 12. The second snap - fit structure and the third snap - fit structure jointly restrict the base body 11 from moving away from the bracket 12 along the preset direction X. In this way, through the restriction of the two snap - fit structures, the bracket 12 and the base 10 can be stably connected together. For example, the preset direction X can be Figure 2 the up - down direction shown in the figure, where the second snap - fit structure can be used to restrict the base body 11 from moving away from the bracket 12 along the direction from bottom to top, and the third snap - fit structure can be used to restrict the base body 11 from moving away from the bracket 12 along the direction from top to bottom.

[0040] Specifically, referring to Figures 3 to 5 , the second snap - fit structure includes a second opening 1211, a tongue plate 111, and a first protrusion 112 provided on the tongue plate 111. The second opening 1211 is provided at one end of the cylinder body 121 away from the flange 122, and the opening direction of the second opening 1211 faces away from the flange 122. The tongue plate 111 is provided on the base body 11. One side of the first protrusion 112 facing away from the flange 122 has an inclined surface 1120, and there is an acute - angle between the inclined surface 1120 and the preset direction X. The cylinder body 121 surrounds the tongue plate 111, and the first protrusion 112 is inserted into the second opening 1211. Among them, the tongue plate 111 can be deformed, and the inclined surface 1120 can guide the first protrusion 112 to be inserted into the second opening 1211 when the tongue plate 111 can be deformed. In the case of adopting this technical solution, by inserting the first protrusion 112 into the second opening 1211, the base body 11 can be prevented from moving away from the bracket 12 along the preset direction X and along the direction towards the second opening 1211. For example, the preset direction X can be Figure 2 the up - down direction shown in the figure. By inserting the first protrusion 112 into the second opening 1211, the base body 11 can be restricted from moving away from the bracket 12 along the direction from bottom to top.

[0041] Referring to Figures 3 to 5 , the third snap - fit structure includes a third opening 1212 and a second protrusion 113. The second protrusion 113 is provided on the outer surface of the base body 11. The third opening 1212 is provided at one end of the cylinder body 121 close to the flange 122 and penetrates the flange 122, and the second protrusion 113 is inserted into the third opening 1212. In the case of adopting this technical solution, by inserting the second protrusion 113 into the second opening 1211, the base body 11 can be prevented from moving away from the bracket 12 along the preset direction X and along the direction towards the third opening 1212. For example, the preset direction X can be Figure 2In the up-down direction of the illustration, by inserting the second protrusion 113 into the third opening 1212, the base body 11 can be restricted from moving away from the bracket 12 in the up-down direction.

[0042] Based on the above-mentioned second clamping structure and third clamping structure, when assembling the base body 11 and the bracket 12 together, the base body 11 can be moved from the side where the flange 122 is located towards the cylinder body 121, and the base body 11 is inserted into the cylinder body 121. During this insertion process, since the second opening 1211 is located at one end of the cylinder body 121 away from the flange 122, and the side of the first protrusion 112 facing away from the flange 122 has an inclined surface 1120, therefore, the inclined surface 1120 of the first protrusion 112 first contacts the cylinder body 121 of the bracket 12. As the base body 11 moves towards the cylinder body 121, under the guidance of the inclined surface 1120, the tongue plate 111 is squeezed by the cylinder body 121 and deformed inward, thereby allowing the first protrusion 112 to enter the cylinder body 121. When the first protrusion 112 encounters the second opening 1211, the tongue plate 111 resumes deformation, and the first protrusion 112 is inserted into the second opening 1211. At the same time, as the base body 11 moves towards the cylinder body 121, the second protrusion 113 can also be correspondingly inserted into the third opening 1212. Through size design, when the first protrusion 112 is inserted into the second opening 1211, the second protrusion 113 can abut against the bottom wall of the third opening 1212, that is, the second protrusion 113 has occupied all the space of the third opening 1212, so that the base body 11 and the bracket 12 can be stably connected together.

[0043] In one example, the push-button switch 1 further includes a circuit structure. When the button 20 is pressed by an external force and pivots from the first position to the second position, it can trigger the circuit structure to achieve conduction disconnection or conduction connection of the circuit structure. When there is no external force, the button 20 can be held at the first position. Refer to Figure 5 and Figure 6 , the base body 11 may include a housing 114 and a housing cover 115. The housing 114 includes a bottom plate and side plates. The housing cover 115 is connected to the side plates to enclose a receiving cavity with the housing 114. The receiving cavity can be used to accommodate the circuit structure. Two fourth openings 1140 may be provided on the side plates of the housing 114. The part of the side plate between the two fourth openings 1140 forms a tongue plate 111. The second protrusion 113 is located on the outer surface of the side plate.

[0044] In a possible embodiment, refer to Figures 3 to 5, the bracket 12 further includes a first surrounding member 123 and a second surrounding member 124. The first surrounding member 123 is connected between the flange 122 and the second surrounding member 124. The second surrounding member 124 surrounds the first surrounding member 123, and the first surrounding member 123 surrounds the flange 122. The spacing between the second surrounding member 124 and the flange 122 in the preset direction X is equal to the width dimension of the first surrounding member 123 in the preset direction X. In this way, when the base 10 is fixed to the installation wall, the flange 122 can contact the installation wall, and there is a spacing between the second surrounding member 124 and the installation wall, and this spacing is approximately equal to the width dimension of the first surrounding member 123 in the preset direction X. Therefore, the user can conveniently apply an external force to the second surrounding member 124 during installation to adjust the position of the base 10 on the installation wall. Since both the first surrounding member 123 and the second surrounding member 124 are covered by the button 20 in the preset direction X, the first surrounding member 123 and the second surrounding member 124 also help to improve the floating effect of the button 20 relative to the installation wall.

[0045] In a possible embodiment, referring to Figure 3 , the button 20 includes a convex plate 22. The number of convex plates 22 is multiple and they are sequentially connected end to end to form a ring-shaped protrusion, and the ring-shaped protrusion surrounds the connecting portion 21 therein. In this way, the ring-shaped protrusion can play a role in strengthening the structural strength of the button 20, and when looking at the button 20 type switch from a direction parallel to the virtual plane Y, the ring-shaped protrusion can play a role in covering the connecting portion 21, thereby helping to improve the aesthetic effect and the floating effect.

[0046] In an example, the orthographic projection of the first surrounding member 123 in the virtual plane Y can surround the orthographic projection of the ring-shaped protrusion in the virtual plane Y. That is, the outer diameter dimension of the ring-shaped protrusion is smaller than the inner diameter dimension of the first surrounding member 123, and the first surrounding member 123 can be sleeved outside the ring-shaped protrusion. In this way, in the preset direction X, the ring-shaped protrusion and the first surrounding member 123 can jointly play a role in covering the connecting portion 21, thereby helping to improve the aesthetic effect and the floating effect.

[0047] In a possible implementation manner, the push-button switch 1 further includes an elastic member, and the elastic member is arranged on the base 10; during the process of the button 20 pivoting from the first position to the second position, the elastic member is pressed against the base 10 by the button 20 and compressed, and the compressed energy released by the elastic member can drive the button 20 to pivot from the second position to the first position. In this way, the automatic rebound of the button 20 can be realized by using the elastic member.

[0048] Further, referring to Figure 3 and Figure 4The push-button switch 1 further includes a hook 23 and a stopper, one of which is provided on the base 10, and the other on the inner surface of the button 20. When the button 20 is in the first position, the elastic member applies a force to the button 20 in a preset direction X and away from the base 10, and the hook 23 is pressed against the stopper under the action of this force. During the movement of the button 20 from the first position to the second position, the hook 23 moves away from the stopper. In this way, the forces applied by the stopper and the elastic member on the hook 23 are opposite, thereby enabling the button 20 to remain in the first position. It should be understood that the stopper is located on the rotation path of the button 20 from the second position to the first position, so that when the button 20 reaches the first position, the stopper can stop the button 20 from further rotation by stopping the hook 23. In this way, when no external force acts on the button 20, the button 20 can be maintained in the first position by the elastic member, the hook 23 and the stop portion. When the button 20 is pressed by an external force and pivoted from the first position to the second position, it can trigger the circuit structure to achieve circuit disconnection or connection.

[0049] Among them, reference Figure 4 The base 10 includes a receiving hole 13, a stopper disposed within the receiving hole 13, and the hook 23 extends into the receiving hole 13 to be restrained by the stopper. Thus, by disposing the stopper within the receiving hole 13 of the base 10, the gap between the button 20 and the base 10 in the predetermined direction X when the button 20 is in the first position can be reduced, thereby enhancing the floating effect. Consequently, the dimensions of the push-button switch 1 in the predetermined direction X can be reduced. Of course, the gap between the button 20 and the base 10 in the predetermined direction X must be sufficient to allow the button 20 to rotate between the first and second positions.

[0050] In one possible embodiment, reference Figure 3 The button 20 includes a pressing protrusion 24 provided on the inner surface thereof, which is used to press the elastic member. Thus, by providing the pressing protrusion 24, the length of the elastic member in the preset direction X can be reduced, thereby reducing the probability of the elastic member being twisted and thus difficult to recover from deformation.

[0051] In one possible embodiment, reference Figure 4, the push-button switch 1 may further include a housing 30. The housing 30 and the base 10 are slidably connected along a preset direction X. The housing 30 is a cylindrical structure with one end open. The housing 30 covers the elastic member and is connected to the elastic member. The housing 30 abuts against the button 20. In this way, the housing 30 is located between the elastic member and the button 20 and can conduct the acting force between the button 20 and the elastic member. When the elastic member is compressed and deformed by the button 20, the housing 30 can move towards the base 10 following the elastic member. When the elastic member resumes its deformation, the housing 30 can move towards the button 20 following the elastic member. Since the housing 30 and the base 10 are slidably connected along the preset direction X, the housing 30 can compress and deform the elastic member along the preset direction X, reducing the probability that the elastic member is twisted and thus difficult to resume its deformation. Among them, the pressing protrusion 24 of the button 20 can press against the housing 30. The elastic member can be a helical spring.

[0052] As can be seen from the above, when installing the push-button switch 1 provided in the present application, the base 10 can be first fixed to the installation wall through the connection hole 1220 on the flange 122, and then the ear plate 211 of the button 20 and the rotating shaft 14 on the base 10 can be connected together.

[0053] It should be noted that according to the needs of implementation, each component / step described in the embodiments of the present application can be split into more components / steps, or two or more components / steps or partial operations of the components / steps can be combined into new components / steps to achieve the purpose of the embodiments of the present application.
