Description
Technical Field
[0001] The present invention relates to a thin switch with a stroke amplification function, belonging to the technical field of electrical accessories. Background Art
[0002] At present, wall switches have been widely used in people's daily lives. Existing wall switches often adopt a rocker switch structure. The rocker switch includes a rocker and a panel. Users can turn on or off the rocker switch by pressing the rocker. However, after the rocker switch is turned on or off, one end of the two ends of the rocker will tilt and protrude. The tilted end has a tilting angle relative to the panel. When the size of the rocker switch needs to be increased, since the tilting angle of the rocker remains unchanged, the sizes of both ends of the rocker also need to be increased, resulting in an increase in the overall thickness of the rocker switch, and the size of the protruding part of the rocker switch relative to the wall surface is relatively large, affecting the aesthetics of the rocker switch. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a thin switch with a stroke amplification function to make the switch more aesthetic.
[0004] To solve the above technical problem, the thin switch with a stroke amplification function of the present invention includes a switch board and a bottom box. One end of the switch board is rotatably connected to the bottom box, and the other end is a free end. A pressing mechanism for pressing to control the on / off of the switch is provided in the bottom box. A lever is provided between the switch board and the bottom box. The lever includes a pressing end and an abutting end respectively located at both ends of the lever and a central axis located between the pressing end and the abutting end. The central axis is rotatably connected to the switch board. The central axis and the switch board are connected to form a first fulcrum. The abutting end contacts the bottom box to form a second fulcrum. The pressing end contacts the pressing mechanism. The free end is pressed to drive the first fulcrum to move along the pressing direction, and the pressing end rotates along the second fulcrum to press the pressing mechanism to control the on / off of the switch.
[0005] After adopting the above structure, first of all, the switch includes a switch board and a bottom box. One end of the switch board is rotatably connected to the bottom box, and the other end is a free end, so that the free end of the switch board can rotate relative to the bottom box. A pressing mechanism for pressing to control the on / off of the switch is provided in the bottom box. The pressing mechanism is a device that is easy for those skilled in the art to think of, such as a push-button switch, etc., so that the user can control the on / off of the switch by pressing. A lever is provided between the switch board and the bottom box. The lever includes a pressing end and an abutting end respectively located at both ends of the lever and a middle shaft located between the pressing end and the abutting end. The middle shaft is rotatably connected to the switch board, so that the pressing end and the abutting end can rotate relative to each other through the middle shaft and rotate relative to the switch board through the middle shaft. The middle shaft is connected to the switch board to form a first fulcrum, and the abutting end contacts the bottom box to form a second fulcrum. The first fulcrum refers to the rotation center of the middle shaft relative to the switch board, and the second fulcrum refers to the point where the abutting end contacts the bottom box. The pressing end contacts the pressing mechanism. The free end is pressed to drive the first fulcrum to move along the pressing direction. The pressing end rotates along the second fulcrum to press the pressing mechanism to control the on / off of the switch, that is, the pressing end can rotate relative to the abutting end and press the pressing mechanism, so that the lever can apply a force to the pressing mechanism, and the pressing end can rotate relative to the abutting end to press the pressing mechanism to achieve stroke amplification.
[0006] Secondly, in the prior art, when the size of the rocker switch needs to be increased, the sizes of both ends of the rocker also need to be increased, resulting in a relatively large size of the protruding part of the rocker switch relative to the wall surface, which affects the aesthetics of the rocker switch. Adopting the above structure, the user controls the on / off of the switch by pressing the free end of the switch board. When the size of the switch needs to be increased, since the lever can achieve stroke amplification, there is no need to increase the size of the switch board. At the same time, when the size of the lever is increased to increase the amplification multiple of the stroke, since the lever is located between the bottom box and the switch board, only the bottom box needs to be buried deeper in the wall, and there is no need to increase the thickness of the switch board, so that the size of the protruding part of the switch relative to the wall surface does not need to be changed, making the switch more beautiful. At the same time, the switch board can be used as an outer shielding shell of the switch to shield the internal structure of the switch, making the switch more beautiful.
[0007] Based on the above structure, one end of the switch board is rotatably connected to the bottom box. When the user presses the free end of the other end of the switch board, the switch board rotates around the end connected to the bottom box and drives the first fulcrum of the lever to move relative to the end where the switch board is connected to the bottom box. The lever drives the pressing end to move and press the pressing mechanism, so that the pressing end can be displaced under the pressing action of the switch board. The abutting end contacts the bottom box to form a second fulcrum, and the pressing end rotates along the second fulcrum to press the pressing mechanism. That is, the bottom box hinders the lever from driving the abutting end to move, and the pressing end can rotate relative to the abutting end and press the pressing mechanism to be displaced, so that the pressing end can be displaced again, thereby realizing stroke amplification, enabling the switch board to control the on / off of the switch without a large displacement, enabling the switch to achieve micro motion control, and at the same time, the size of the protruding part of the switch relative to the wall surface can be smaller, enabling the switch to be a thin switch.
[0008] Based on the above structure, through the stroke amplification of the lever, the switch board can smoothly control the on / off of the switch without a large displacement. When it is necessary to increase the magnification of the switch stroke amplification, the length of the pressing end and / or the length of the abutting end and / or the position of the central axis can be changed to change the distance between the pressing end and the abutting end and the central axis and / or the position where the central axis is connected to the switch board, so that the lever can achieve stroke amplification to adapt to different environments, thereby increasing the applicable range of the switch. At the same time, when the size of the lever increases, the overall thickness of the switch increases. The depth at which the bottom box is embedded in the wall can be changed so that the thickness of the protruding part of the switch relative to the wall surface remains unchanged, thereby optimizing the switch structure and enabling the switch to have a large applicable range while maintaining beauty.
[0009] Preferably, the lever includes a first rod and a second rod, and the first rod intersects with the second rod, and the intersection point is located between the end where the switch board is connected to the bottom box and the free end.
[0010] Preferably, the pressing mechanism includes a pressing piece, a rocker arm that rotates under the pressure of the pressing piece, a moving contact piece and a moving contact. A static contact is provided in the bottom box. The pressing end contacts the pressing piece. The moving contact piece is rotatably connected to the bottom box. Moving contacts are provided at both ends of the moving contact piece. One end of the rocker arm is rotatably connected to the bottom box, and the other end is in contact with the moving contact piece. When the rocker arm rotates, it drives the moving contact piece to rotate relative to the bottom box. When the moving contact piece rotates, it drives the moving contacts at both ends thereof to contact or separate from the static contact.
[0011] Preferably, a first guiding inclined surface is provided on the pressing piece, and a second guiding inclined surface parallel to the first guiding inclined surface is provided on the rocker arm. When the pressing piece moves, it contacts and presses the second guiding inclined surface through the first guiding inclined surface to drive the rocker arm to rotate.
[0012] Preferably, first guiding inclined surfaces are provided at both ends of the pressing member along a direction perpendicular to the pressing direction, and second guiding inclined surfaces are provided at both ends of the rocker arm along a direction perpendicular to the pressing direction.
[0013] Preferably, one end of each first guiding inclined surface is connected to the pressing member, and the other end is the free end of the first inclined surface. One end of each second guiding inclined surface is connected to the rocker arm, and the other end is the free end of the second inclined surface. The distance between the free ends of the first inclined surfaces at both ends of the pressing member is equal to the distance between the free ends of the second inclined surfaces at both ends of the rocker arm.
[0014] Preferably, a return spring for resetting the pressing member is provided in the bottom box, and the direction of elastic deformation of the return spring is the same as the direction of the pressure applied by the pressing end to the pressing member.
[0015] Preferably, the pressing member includes a pressing plate and a slider. The pressing plate is in contact with the pressing end, and the slider is in contact with the rocker arm. The slider slides relative to the pressing plate along a direction perpendicular to the pressure applied by the pressing end to the pressing member, and a sliding spring for resetting the slider is provided in the bottom box.
[0016] Preferably, the pressing mechanism is a push-button switch.
[0017] Preferably, the bottom box includes a mounting bracket. A buckle is provided on the switch board, and a cylindrical protrusion for engaging with the buckle is provided on the mounting bracket. The switch board rotates relative to the cylindrical protrusion through the buckle to achieve relative rotation with the bottom box.

[0027] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without making creative efforts all fall within the protection scope of the present invention.
[0028] In the following description, terms such as "inner", "outer", "upper", "lower", "left", "right", etc., indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. It is only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be construed as a limitation to the present invention.
[0029] Embodiment 1:
[0030] As Figures 1 to 7 shown, the preferred structure of the thin switch with a stroke amplification function in this embodiment includes a switch board 1 and a bottom box 2. One end of the switch board 1 is rotatably connected to the bottom box 2, and the other end is a free end. A pressing mechanism for pressing to control the on / off of the switch is provided in the bottom box 2. A lever 3 is provided between the switch board 1 and the bottom box 2. The lever 3 includes a pressing end 4 and an abutting end 5 respectively located at both ends of the lever 3 and a central axis 6 located between the pressing end 4 and the abutting end 5. The central axis 6 is rotatably connected to the switch board 1. The central axis 6 is connected to the switch board 1 to form a first fulcrum. The abutting end 5 contacts the bottom box 2 to form a second fulcrum. The pressing end 4 contacts the pressing mechanism. The free end is pressed to drive the first fulcrum to move along the pressing direction. The pressing end 4 rotates along the second fulcrum to press the pressing mechanism to control the on / off of the switch.
[0031] After adopting the above structure, first of all, the switch includes a switch board 1 and a bottom box 2. One end of the switch board 1 is rotatably connected to the bottom box 2, and the other end is a free end, so that the free end of the switch board 1 can rotate relative to the bottom box 2. A pressing mechanism for pressing to control the on / off of the switch is provided in the bottom box 2. The pressing mechanism is a device that is easy for those skilled in the art to think of, such as a push-button switch, etc., so that the user can control the on / off of the switch by pressing. A lever 3 is provided between the switch board 1 and the bottom box 2. The lever 3 includes a pressing end 4 and an abutting end 5 located at both ends of the lever 3 and a central axis 6 located between the pressing end 4 and the abutting end 5. The central axis 6 is rotatably connected to the switch board 1, so that the pressing end 4 and the abutting end 5 can rotate relative to each other through the central axis 6 and rotate relative to the switch board 1 through the central axis 6. The central axis 6 is connected to the switch board 1 to form a first fulcrum, and the abutting end 5 contacts the bottom box 2 to form a second fulcrum. The first fulcrum refers to the rotation center of the central axis 6 relative to the switch board 1, and the second fulcrum refers to the point where the abutting end 5 contacts the bottom box 2. The pressing end 4 contacts the pressing mechanism. The free end is pressed to drive the first fulcrum to move along the pressing direction. The pressing end 4 rotates along the second fulcrum to press the pressing mechanism to control the on / off of the switch, that is, the pressing end 4 can rotate relative to the abutting end 5 and press the pressing mechanism, so that the lever 3 can apply a force to the pressing mechanism, so that the pressing end 4 can rotate relative to the abutting end 5 to press the pressing mechanism to achieve stroke amplification.
[0032] Secondly, in the prior art, when the size of the rocker switch needs to be increased, the sizes of both ends of the rocker also need to be increased, which leads to a relatively large size of the protruding part of the rocker switch relative to the wall, affecting the aesthetics of the rocker switch. Adopting the above structure, the user controls the on / off of the switch by pressing the free end of the switch board 1. When the size of the switch needs to be increased, since the lever 3 can achieve stroke amplification, there is no need to increase the size of the switch board 1. At the same time, when the size of the lever 3 is increased to increase the amplification factor of the stroke, since the lever 3 is located between the bottom box 2 and the switch board 1, it only needs to bury the bottom box 2 deeper in the wall without increasing the thickness of the switch board 1, so that the size of the protruding part of the switch relative to the wall does not need to be changed, making the switch more beautiful. At the same time, the switch board 1 can be used as an outer shielding shell of the switch to shield the internal structure of the switch, making the switch more beautiful.
[0033] Based on the above structure, one end of the switch board 1 is rotatably connected to the bottom box 2. When the user presses the free end of the other end of the switch board 1, the switch board 1 rotates around the end connected to the bottom box 2 and drives the first fulcrum of the lever 3 to move relative to the end where the switch board 1 is connected to the bottom box 2. The lever 3 drives the pressing end 4 to move and press the pressing mechanism, so that the pressing end 4 can be displaced under the pressing action of the switch board 1. The abutting end 5 contacts the bottom box 2 to form a second fulcrum. The pressing end 4 rotates along the second fulcrum to press the pressing mechanism, that is, the bottom box 2 hinders the lever 3 from driving the abutting end 5 to move. The pressing end 4 can rotate relative to the abutting end 5 and press the pressing mechanism to be displaced, so that the pressing end 4 can be displaced again, thereby realizing stroke amplification, so that the switch board 1 does not need a large displacement to control the on-off of the switch, so that the switch can realize micro motion control. At the same time, the size of the protruding part of the switch relative to the wall surface can be smaller, so that the switch can be a thin switch.
[0034] Based on the above structure, through the stroke amplification of the lever 3, the switch board 1 can smoothly control the on-off of the switch without a large displacement. When it is necessary to increase the magnification of the switch stroke amplification, the length of the pressing end 4 and / or the length of the abutting end 5 and / or the position of the central axis 6 can be changed to change the distance between the pressing end 4 and the abutting end 5 and the central axis 6 and / or the position where the central axis 6 is connected to the switch board 1, so that the lever 3 can realize stroke amplification to adapt to different environments, thereby increasing the applicable range of the switch. At the same time, when the size of the lever 3 increases, the overall thickness of the switch increases. The depth at which the bottom box 2 is embedded in the wall can be changed so that the thickness of the protruding part of the switch relative to the wall surface remains unchanged, thereby optimizing the switch structure and enabling the switch to have a large applicable range while maintaining beauty.
[0035] Wherein, the contact between the pressing end 4 and the pressing mechanism means that the pressing end 4 is always in contact with the pressing mechanism, that is, when pressing or not pressing, the pressing end 4 is in contact with the pressing mechanism.
[0036] In addition, when pressing, the pressing end 4 rotates relative to the abutting end 5 to press the pressing mechanism, while the abutting end 5 slides on the surface in contact with the bottom box 2. The surface of the abutting end 5 in contact with the bottom box 2 can be parallel to the switch board 1 or not parallel, as long as the pressing end 4 can rotate along the second fulcrum to press the pressing mechanism.
[0037] In order to enable the pressing end 4 to rotate relative to the abutting end 5 to press the pressing mechanism, in this embodiment, it is preferred that the lever 3 includes a first rod and a second rod. The first rod and the second rod intersect, and the intersection point is located between the end where the switch board 1 is connected to the bottom box 2 and the free end. That is, the included angle between the first rod and the second rod can be an acute angle, a right angle or an obtuse angle. It only needs to ensure that the pressing end 4 can rotate along the second fulcrum to press the pressing mechanism. The first rod and the second rod are connected by a central axis 6, and the central axis 6 is located at the intersection position of the first rod and the second rod.
[0038] In order to enable the pressing mechanism to control the on-off of the switch, in this embodiment, it is preferred that the pressing mechanism includes a pressing member, a rocker arm 10 that rotates under the pressure of the pressing member, a moving contact piece 11, and a moving contact point 12. A static contact point 9 is provided in the bottom box. The pressing end 4 is in contact with the pressing member. The moving contact piece 11 is rotatably connected to the bottom box. Moving contact points 12 are provided at both ends of the moving contact piece 11. One end of the rocker arm 10 is rotatably connected to the bottom box 2, and the other end is in contact with the moving contact piece 11. When the rocker arm 10 rotates, it drives the moving contact piece 11 to rotate relative to the bottom box 2. When the moving contact piece 11 rotates, it drives the moving contact points 12 at both ends thereof to contact or separate from the static contact point 9. With this structure, the rocker arm 10 rotates relative to the bottom box 2 under the pressing force of the pressing member, and when rotating, it drives the moving contact piece 11 to rotate by pressing the moving contact piece 11. When the moving contact piece 11 rotates, it drives the moving contact points 12 at both ends thereof to contact or separate from the static contact point 9 to achieve the on-off of the switch.
[0039] In order to enable the pressing member to press and control the rotation of the rocker arm 10, in this embodiment, it is preferred that a first guiding inclined surface is provided on the pressing member, and a second guiding inclined surface parallel to the first guiding inclined surface is provided on the rocker arm 10. When the pressing member moves, it contacts and presses the second guiding inclined surface through the first guiding inclined surface to drive the rocker arm 10 to rotate. When the first guiding inclined surface on the pressing member presses the second guiding inclined surface on the rocker arm 10, the pressure exerted by the first guiding inclined surface on the second guiding inclined surface can be decomposed into a force along the pressing direction and a force perpendicular to the pressing direction. The first guiding inclined surface receives the reaction force from the second guiding inclined surface along the direction perpendicular to the pressing direction, so that the rocker arm 10 can rotate under the action of the first guiding inclined surface, and the pressing member can move along the direction perpendicular to the pressing direction under the reaction force of the second guiding inclined surface.
[0040] In order to enable the pressing member to control the opening and closing of the switch, in this embodiment, it is preferably provided that both ends of the pressing member along the direction perpendicular to the pressing direction are provided with first guiding inclined surfaces, and both ends of the rocker arm 10 along the direction perpendicular to the pressing direction are provided with second guiding inclined surfaces. The pressing member contacts the second guiding inclined surface at one end of the rocker arm 10 through the first guiding inclined surface at one end thereof to control the rocker arm 10 to rotate forward, thereby controlling the switch to open, and contacts the second guiding inclined surface at the other end of the rocker arm 10 through the first guiding inclined surface at the other end thereof to control the rocker arm 10 to rotate reversely, thereby controlling the switch to close. The forward direction means that the switch can be controlled to open when the rocker arm 10 rotates along this direction, and the reverse rotation means that the switch can be controlled to close when the rocker arm 10 rotates along this direction, so that the pressing member can control the opening and closing of the switch.
[0041] In order to prevent the second guiding inclined surfaces at both ends of the rocker arm 10 from limiting the first guiding inclined surfaces at both ends of the pressing member and enable the first guiding inclined surfaces at both ends of the pressing member to contact the second guiding inclined surfaces at both ends of the rocker arm 10 to control the rotation of the rocker arm 10, in this embodiment, it is preferably provided that one end of the first guiding inclined surface is connected to the pressing member, and the other end is the free end of the first inclined surface. One end of the second guiding inclined surface is connected to the rocker arm 10, and the other end is the free end of the second inclined surface. The distance between the free ends of the first inclined surfaces at both ends of the pressing member is equal to the distance between the free ends of the second inclined surfaces at both ends of the rocker arm 10. When the first guiding inclined surface at one end of the pressing member contacts the second guiding inclined surface at one end of the rocker arm 10, due to the reaction of the second guiding inclined surface on the first guiding inclined surface, the pressing member moves along this end. At this time, the pressing member displaces in the pressing direction, and the rocker arm 10 does not displace. The first guiding inclined surface at the other end of the pressing member moves together with the pressing member and displaces into the groove between the second guiding inclined surfaces at both ends of the rocker arm 10, thereby preventing the second guiding inclined surfaces at both ends of the arm from limiting the first guiding inclined surfaces at both ends of the pressing member and hindering the movement of the pressing member. When the pressing ends, the pressing member is reset under the action of the sliding spring 14. The distance between the free ends of the first inclined surfaces at both ends of the pressing member being equal to the distance between the free ends of the second inclined surfaces at both ends of the rocker arm 10 enables the other end of the pressing member to contact the second guiding inclined surface at the other end of the rocker arm 10 after resetting to control the rocker arm 10 to rotate reversely, thereby preventing the second guiding inclined surfaces at both ends of the rocker arm 10 from limiting the first guiding inclined surfaces at both ends of the pressing member and enabling the first guiding inclined surfaces at both ends of the pressing member to contact the second guiding inclined surfaces at both ends of the rocker arm 10 to control the rotation of the rocker arm 10.
[0042] In order to enable the pressing member to be reset after being pressed, in this embodiment, it is preferably provided that a reset spring 13 for resetting the pressing member is provided in the bottom box 2. The direction of elastic deformation of the reset spring 13 is the same as the direction of the pressure applied by the pressing end 4 to the pressing member. The pressing member can be reset along the pressing direction through the reset spring 13, so that the pressing member can repeatedly press to control the on-off of the switch, thereby optimizing the structure and enabling the switch to work better.
[0043] In order to optimize the structure of the pressing member, as Figure 5 shown, in this embodiment, it is preferred that the pressing member includes a pressing plate 7 and a slider 8. The pressing plate 7 contacts the pressing end 4, and the slider 8 contacts the rocker arm 10. The slider 8 slides relative to the pressing plate 7 in a direction perpendicular to the pressure applied by the pressing end 4 to the pressing member. A sliding spring 14 for resetting the slider 8 is provided in the bottom case 2. The slider 8 is reset by the sliding spring 14 so that the pressing member can contact the second guiding inclined surfaces at both ends of the rocker arm 10 through the first guiding inclined surfaces at both ends to control the rotation of the rocker arm 10 and further control the on / off of the switch, thereby optimizing the mechanism of the pressing member and enabling the switch to work better.
[0044] In order to optimize the structure of the switch, as Figure 6 and Figure 7 shown, in this embodiment, it is preferred that the bottom case 2 includes a mounting bracket 15. A buckle 16 is provided on the switch board 1, and a cylindrical protrusion 17 for engaging with the buckle 16 is provided on the mounting bracket 15. The switch board 1 rotates relative to the cylindrical protrusion 17 through the buckle 16 to achieve relative rotation with the bottom case 2. The bottom case 2 is encapsulated by the mounting bracket 15, so that the internal structure of the bottom case 2 can be shielded by the mounting bracket 15, thereby making the switch more beautiful. The switch board 1 can be rotatably connected to the bottom case 2 and can also be detachable from the bottom case 2 by engaging the buckle 16 with the cylindrical protrusion 17. When the switch board 1 is damaged, only the switch board 1 needs to be replaced, thereby optimizing the structure of the switch.
[0045] Embodiment 2:
[0046] The difference between this embodiment and Embodiment 1 is that in this embodiment, the pressing mechanism is a push-button switch, and the pressing end presses the push-button switch to achieve the on / off of the switch. The push-button switch refers to a switch that uses a button to push a transmission mechanism to connect or disconnect a moving contact and a static contact and achieve circuit switching. With this structure, the structure is simple and the processing is convenient. This embodiment can also achieve the technical effects of Embodiment 1.
[0047] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
