Description

[0002] As switches gradually develop towards ultra-thin, flat and simple directions, flat self-resetting push switches (referred to as push switches) come into being.

[0003] Purely flat means that the button of the push switch is always parallel to the wall or table on which the push switch is installed when moving along the pressing direction, and basically does not tilt relative to the wall. Self-resetting means that after the force of pressing the button is cancelled, the button automatically resets to the initial state under the action of the reset mechanism inside the push switch.

[0044] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0045] The disclosed embodiments relate to a pressing mechanism of a push switch, which is specifically a flat self-resetting push switch, referred to as a push switch. Flat means that the button of the push switch is always parallel to the wall or desktop on which the push switch is installed when moving along the pressing direction, and basically does not tilt relative to the wall. Self-resetting means that after the force of pressing the button is cancelled, the button automatically resets to the initial state under the action of the reset mechanism inside the push switch.

[0046] At present, how to achieve pure flat movement of the button of the push switch is the research direction that technicians in this field are committed to. For example, the current idea of ​​achieving pure flatness of the push switch is to concentrate the force of the driving reset mechanism in the middle position of the button, because only when the button is pressed in the middle position, the button will not be easily tilted, thus achieving pure flatness. However, when the user presses the button, he or she may not press in the middle position of the button, but generally presses at the edge of the button. In this case, multiple driving arms need to be arranged under the button to transmit the user's pressing force to the middle position of the button through multiple driving arms, and then trigger the reset mechanism.

[0047] However, the above-mentioned push switch is generally implemented by a large number of driving arms, such as four driving arms, which are distributed on the button in a cross-diagonal manner to transmit the force at various positions on the button to the intersection position. The structure of this push switch is relatively complex.

[0048] This embodiment provides a pressing mechanism with a simple structure. When a user presses a button, the button is not likely to flip over, thus achieving pure flat movement.

[0049] The pressing mechanism can be applied to a mechanical switch, for example, a contact switch in a mechanical switch, or an electronic switch. This embodiment does not limit the application scenario of the pressing mechanism, and the accompanying drawings take the application in a mechanical switch as an example.

[0050] like Figure 1 As shown in FIG. 1 , it is a schematic diagram of the structure of the push switch. Figure 2 As shown in FIG. 1 , it is a schematic diagram of the explosion structure of the push switch. Figures 3 to 5 The figures are schematic diagrams of the hidden base assembly 300 of the push switch. Figure 3 The schematic diagram is that the button of the push switch is in the initial position and the push switch is in the disconnected state. Figure 4 The schematic diagram is that the button of the push switch is pressed to the bottom and the push switch is in the on state. Figure 5 The schematic diagram shows that the button of the push switch is reset to the initial position and the push switch is in the on state.

[0051] refer to Figure 2 As shown, the push switch includes a push mechanism 100, a reset mechanism 200, a base assembly 300 and a switch module 400, wherein the base assembly 300 includes a base 301 and a pressure plate 302, wherein the base 301 is a box-shaped structure without a cover, and the pressure plate 302 is covered and fixed on the base 301. Of course, the base 301 and the pressure plate 302 can also be integrally formed.

[0052] refer to Figures 3 to 5 As shown, the switch module 400 includes a transition piece 401, a moving touch plate 402, two stationary touch plates 403, a first terminal 404 and a second terminal 405, wherein the moving touch plate 402 is connected to the transition piece 401, one of the two stationary touch plates 403 is connected to the first terminal 404, and the other stationary touch plate 403 is connected to the second terminal 405, and the transition piece 401 rotates and swings left and right, driving the moving touch plate 402 to connect or disconnect with one of the stationary touch plates 403, so as to exercise the on and off functions of the push switch.

[0053] like Figure 3 And refer to Figure 1 As shown, the switch modules 400 are all assembled in the chamber formed by the base 301 and the pressure plate 302 , and the transition piece 401 can rotate and swing relative to the base 301 and the pressure plate 302 .

[0054] The reset mechanism 200 may be located in the base 301 or not, but the reset mechanism 200 is located between the transition piece 401 and the pressing mechanism 100. For example, the reset mechanism 200 is located between the transition piece 401 and the button 1, so that when the button 1 is pressed, the reset mechanism 200 can drive the transition piece 401 to swing.

[0055] refer to Figure 1As shown, the pressing mechanism 100 covers and is assembled on the base assembly 300, for example, the partition plate 4 of the pressing mechanism 100 is engaged with the pressing plate 302 of the base assembly 300. The pressing mechanism 100 also abuts against the reset mechanism 200, for example, the button 1 of the pressing mechanism 100 abuts against the reset mechanism 200.

[0056] refer to Figures 3 to 5 As shown, when the button 1 is pressed, the button 1 drives the transition piece 401 to swing through the reset mechanism 200 , thereby performing the switch function. When the button 1 is no longer pressed, the button 1 is reset to the initial position under the action of the reset mechanism 200 .

[0057] The above is an introduction to the features of the push switch. The features of the push mechanism 100 will be introduced below.

[0058] like Figure 6 As shown in FIG. 1 , it is an exploded schematic diagram of the pressing mechanism. Figure 7 and Figure 8 FIG. 1 is a schematic diagram of a pressing mechanism, wherein: Figure 7 is a schematic diagram of button 1 in the initial position. Figure 8 This is a diagram showing Button 1 being fully pressed.

[0059] refer to Figure 6 As shown, the pressing mechanism includes a button 1, a first lever 2, a second lever 3 and a partition 4, wherein the button 1 generally includes a cover and four side walls, the first lever 2 and the second lever 3 are both plate-shaped levers, and the partition 4 also has a plate-shaped structure.

[0060] Among them, the first lever 2 and the second lever 3 can both be flat-plate structures, or can be bent plates bent at the fulcrum. This embodiment does not limit the specific shapes of the first lever 2 and the second lever 3. The flat-plate structure is used as an example in the accompanying drawings. The flat-plate structure is conducive to reducing the thickness of the pressing mechanism.

[0061] In one example, reference Figure 6 As shown, the first lever 2 of the plate-like structure has a first end a, a fulcrum O1 and a second end b which are all cylindrical structures. Figure 6 As shown, the first end a, the fulcrum O2 and the second end b of the second lever 3 are also cylindrical structures.

[0062] refer to Figure 7 As shown, the first lever 2 and the second lever 3 are located between the button 1 and the partition 4. For example, the first lever 2 and the second lever 3 are arranged symmetrically between the button 1 and the partition 4.

[0063] The connection relationship among the button 1, the first lever 2, the second lever 3 and the partition 4 is as follows.

[0064] The first end a of the first lever 2 abuts against the first side of the button 1, the first end a of the second lever 3 abuts against the second side of the button 1, the fulcrum O1 of the first lever 2 and the fulcrum O2 of the second lever 3 are both rotatably connected to the partition 4, and the second end b of the first lever 2 and the second end b of the second lever 3 are hinged (such as hinged by a rotational connection).

[0065] The first side and the second side of the button 1 are two opposite sides of the button 1 , for example, the first side is the left side of the button 1 , and the second side is the right side of the button 1 .

[0066] In one example, the first lever 2 abuts against the button 1, which means that the first lever 2 and the button 1 are always in an abutting state. For example, when the button 1 is being pressed and when the button 1 is being reset, the first lever 2 and the button 1 remain in an abutting state.

[0067] Likewise, the second lever 3 abuts against the button 1 , and the second lever 3 and the button 1 are always in an abutting state, including when the button 1 is being pressed and when the button 1 is being reset.

[0068] In one example, because the button 1 is always in contact with the first lever 2 and the second lever 3 , when the button 1 moves in the pressing direction, the first lever 2 and the second lever 3 move along with the button 1 .

[0069] In order to enable the first lever 2 and the second lever having a hinged relationship to move with the button 1, accordingly, the first end a of the first lever 2 can move in a first direction relative to the button 1 (such as translational movement), the fulcrum O1 of the first lever 2 can move in the first direction relative to the partition 4 (such as translational movement), and the second end b of the first lever 2 can move in the second direction relative to the partition 4 (such as translational movement).

[0070] The first direction and the second direction are both parallel to the rotation plane of the first lever 2, and the second direction is the pressing direction. The first direction and the second direction intersect, such as perpendicularly intersecting, but of course they may not be perpendicular. The figure shows a perpendicular example. Figure 7 As shown, the rotation plane is a vertical plane, the second direction is a vertical direction, and the first direction is a horizontal direction.

[0071] Similarly, the first end a of the second lever 3 can move in the first direction relative to the button 1, the fulcrum O2 of the second lever 3 can move in the first direction relative to the partition 4, and the second end b of the second lever 3 can move in the second direction relative to the partition 4.

[0072] In one example, in order to enable the first lever 2 and the second lever 3 to move between the button 1 and the partition 4, and also to enable the button 1 to move in the first direction, accordingly, reference Figure 7As shown, when the button 1 is in the initial position, there is a distance H between it and the partition 4, and the distance H is used to allow the button 1 to move.

[0073] So, reference Figure 7 and Figure 8 As shown, button 1 is switching from the initial position to being fully pressed, for example, referring to Figure 7 As shown, the button 1 is in the initial position. When the first side of the button 1 is pressed, that is, when the button 1 is in position A, the first end a of the first lever 2 moves downward with the button 1, and according to the lever principle, the second end b of the first lever 2 moves upward. Since the second end b of the first lever 2 and the second end b of the second lever 3 are hinged, the second end b of the second lever 3 and the second end b of the first lever 2 move upward synchronously. The second end b of the second lever 3 moves upward, and according to the lever principle, the first end a of the second lever 3 moves downward. The first end a of the second lever 3 abuts against the second side of the button 1, so the button 1 also moves downward on the second side. Therefore, referring to Figure 7 As shown, when the button 1 is pressed at position A of the button 1 , the button 1 also moves at position B and moves synchronously with position A.

[0074] It can be seen that when the first side of the button 1 is pressed, the second side of the button 1 will also move downward synchronously under the action of the first lever 2 and the second lever 3. It can be seen that when any position of the button 1 is pressed, as long as the movement of the first lever 2 is triggered, the second lever 3 will be linked, or as long as the movement of the second lever 3 is triggered, the first lever 2 will be linked. Once the first lever 2 and the second lever 3 are linked, the force on the button 1 will be uniform, and each position of the button 1 will move upward or downward as a whole, thereby realizing the pure flat movement of the button 1.

[0075] The pure flat movement of the button 1 in this embodiment does not transmit the force at any point to the middle position of the button 1, but makes the various positions of the button 1 evenly stressed through the first lever 2 and the second lever 3, thereby achieving a truly pure flat effect.

[0076] In addition, the plate-like structure of the first lever 2 and the second lever 3 increases the contact area between the first lever 2 and the button 1, as well as the contact area between the second lever 3 and the button 1, which is conducive to realizing that pressing any position of the button 1 can trigger the movement of the first lever 2 and the second lever 3, thereby realizing the full-area pressing of the button 1. The full-area pressing means that pressing any position of the button 1 can realize the switch function.

[0077] In one example, the pressing mechanism directly drives the reset mechanism 200 via the button 1 , and accordingly, the button 1 abuts against the top of the reset mechanism 200 .

[0078] For example, Fig. 9As shown, it is a schematic diagram of the structure of the button 1. The button 1 has a rib 13 on the inner surface facing the partition 4. Figure 6 As shown, the first lever 2 , the second lever 3 and the partition 4 all have openings, and the rib 13 of the button 1 passes through the first opening 22 of the first lever 2 , the second opening 31 of the second lever 3 and the third opening 46 of the partition 4 , and abuts against the reset mechanism 200 .

[0079] In another example, the rib 13 can also be set on the reset mechanism 200. Then, the rib on the top of the reset mechanism 200 passes through the first opening 22 of the first lever 2, the second opening 31 of the second lever 3 and the third opening 46 of the partition 4, and abuts against the inner surface of the button 1.

[0080] In another example, the inner surface of the button 1 and the top of the reset mechanism 200 both have ribs, and the ribs of the button 1 and the ribs of the reset mechanism 200 pass through the first opening 22 of the first lever 2, the second opening 31 of the second lever 3 and the third opening 46 of the partition 4, and abut against each other.

[0081] In this embodiment, the convex rib is set on the inner surface of the button 1 as an example. Fig. 9 As shown, the rib 13 can be arranged on the inner surface of the button 1 and at the center thereof.

[0082] Then, reference Figure 6 As shown, a third opening 46 for the convex rib 13 to pass through is opened in the central area of ​​the partition 4, a first opening 22 is opened at a position close to the second end b of the first lever 2, and a second opening 31 is opened at a position close to the second end b of the second lever 3. After the first lever 2 and the second lever 3 are hinged, the first opening 22 of the first lever 2 and the second opening 31 of the second lever 3 form a closed opening equivalent to the third opening 46 for the convex rib 13 to pass through.

[0083] As described above, the first end a of the first lever 2 abuts against the first side of the button 1, and the first end a of the second lever 3 abuts against the second side of the button 1. In one example, the abutment can be achieved through a snap-fit ​​structure. For example, the first end a of the first lever 2 abuts against the inner surface of the button 1 on the first side of the button 1 through a snap-fit ​​structure, and the snap-fit ​​structure can also enable the first end a of the first lever 2 to move relative to the button 1 in the first direction, but restrict the movement in the second direction (i.e., in the second direction, the first end of the first lever 2 and the button 1 move synchronously). Similarly, the first end a of the second lever 3 abuts against the inner surface of the button 1 on the second side of the button 1 through a snap-fit ​​structure, and the snap-fit ​​structure can also enable the first end a of the second lever 3 to move relative to the button 1 in the first direction, but restrict the movement in the second direction (i.e., in the second direction, the first end of the second lever 3 and the button 1 move synchronously).

[0084] For example, refer to Figure 7 As shown, the lower surface of the button 1 facing the partition 4 has a first slot 11 at a first side position and a second slot 12 at a second side position, and the notches of the first slot 11 and the second slot 12 are opposite. The first end a of the first lever 2 is located in the first slot 11 and abuts against the slot wall of the first slot 11, and the first end a of the second lever 3 is located in the second slot 12 and abuts against the slot wall of the second slot 12.

[0085] refer to Figure 7 and Figure 8 As shown, the first slot 11 enables the first end a of the first lever 2 and the button 1 to move synchronously in the second direction (i.e., the pressing direction), and enables the first end a of the first lever 2 to move in translation relative to the button 1 in the first direction (i.e., the horizontal direction). The second slot 12 enables the first end a of the second lever 3 and the button 1 to move synchronously in the second direction (i.e., the pressing direction), and enables the first end a of the second lever 3 to move in translation relative to the button 1 in the first direction (i.e., the horizontal direction).

[0086] In one example, reference Fig. 9 As shown, the number of the first card slots 11 can be two, located on the first side of the button 1 and at both ends of the button 1 along the width direction, and the number of the second card slots 12 is also two, located on the second side of the button 1 and at both ends of the button 1 along the width direction.

[0087] In another example, the number of first card slots 11 can be even greater, and multiple first card slots 11 are on the first side of the button 1 and arranged in sequence along the width direction of the button 1, and the number of second card slots 12 is also multiple, and multiple second card slots 12 are on the second side of the button 1 and arranged in sequence along the width direction of the button 1.

[0088] In another example, the number of the first card slot 11 may be one, and the first card slot 11 is in a strip shape, located at the first side of the button 1 and distributed along the width direction of the button 1. The number of the second card slot 12 may also be one, and the second card slot 12 is in a strip shape, located at the second side of the button 1 and distributed along the width direction of the button 1.

[0089] The first side and the second side of the button 1 may be two sides that are opposite to each other along the length direction, and the length direction and the width direction of the button 1 are perpendicular to each other.

[0090] It should be pointed out that the first slot 11 described above can be replaced by a protruding structure, and the first end a of the first lever 2 has a slot, which can also realize that the first end a of the first lever 2 is engaged with the inner surface of the button 1 at the first side of the button 1, so that the first lever 2 and the button 1 can move relative to each other in the first direction and move synchronously in the second direction. Similarly, the second slot 12 described above can be replaced by a protruding structure, and the first end a of the second lever 3 has a slot, which can also realize that the first end a of the second lever 3 is engaged with the inner surface of the button 1 at the second side of the button 1, so that the second lever 3 and the button 1 can move relative to each other in the first direction and move synchronously in the second direction.

[0091] Among them, this embodiment does not limit how the button 1 and the first end of the first lever 2 are abutted, and how the button 1 and the first end of the second lever 3 are abutted. It can be achieved that the button 1 and the first lever 2 can move relative to each other in the first direction and move synchronously in the second direction, and the button 1 and the second lever 3 can move relative to each other in the first direction and move synchronously in the second direction.

[0092] As described above, the fulcrum O1 of the first lever 2 and the fulcrum O2 of the second lever 3 are both rotatably connected to the partition 4. Therefore, the first lever 2 has a rotating structure at the fulcrum O1, and the partition 4 has a rotating structure, so that the first lever 2 is rotatably connected to the partition 4 at the fulcrum O1. Similarly, the second lever 3 has a rotating structure at the fulcrum O2, and the partition 4 has a rotating structure, so that the second lever 3 is rotatably connected to the partition 4 at the fulcrum O2.

[0093] For example, Figure 6 And refer to Figure 7 As shown, the partition 4 has a first side rib 41 and a second side rib 42 that are relatively positioned, the first lever 2 and the second lever 3 are both located between the first side rib 41 and the second side rib 42, and the fulcrum O1 of the first lever 2 is rotationally connected to the first side rib 41 and the second side rib 42, and the fulcrum O2 of the second lever 3 is rotationally connected to the first side rib 41 and the second side rib 42.

[0094] In one example, the first lever 2 has a first rotating shaft at both sides along the width direction and at the fulcrum O1, and the first side rib 41 and the second side rib 42 have a collinear first rotating shaft hole 43, then the first rotating shafts on both sides of the first lever 2 can be assembled in the first rotating shaft hole 43 of the first side rib 41 and the first rotating shaft hole 43 of the second side rib 42. Of course, the first rotating shaft hole can also be set on the first lever 2, and the first rotating shaft is set on the first side rib 41 and the second side rib 42.

[0095] Similarly, the second lever 3 has a second rotating shaft at both sides along the width direction and at the fulcrum O2, and the first side rib 41 and the second side rib 42 have a collinear second rotating shaft hole 44, so the second rotating shafts on both sides of the second lever 3 can be assembled in the second rotating shaft hole 44 of the first side rib 41 and the second rotating shaft hole 44 of the second side rib 42. Of course, the second rotating shaft hole can also be set on the second lever 3, and the second rotating shaft is set on the first side rib 41 and the second side rib 42.

[0096] Regardless of whether the shaft hole is arranged on the lever or on the side rib, in order to enable the fulcrum of the lever to move relative to the partition 4 in the first direction (i.e., the horizontal direction), correspondingly, reference Figure 7 As shown, the first rotation shaft hole 43 and the second rotation shaft hole 44 are both bar-shaped holes parallel to the first direction.

[0097] In this way, the first lever 2 rotates at the fulcrum O1 and is accompanied by a translational movement along the first direction, and the second lever 3 rotates at the fulcrum O2 and is accompanied by a translational movement along the first direction.

[0098] It should be noted that the first side rib 41 and the second side rib 42 of the partition 4 also have the function of limiting the movement of the first lever 2 and the second lever 3 along the width direction of the partition 4 .

[0099] As described above, the second end b of the first lever 2 and the partition 4 can move relative to each other in the second direction, but cannot move relative to each other in the first direction. The second end b of the second lever 3 and the partition 4 can also move relative to each other in the second direction, but cannot move relative to each other in the first direction.

[0100] Correspondingly, such as Figure 6 And refer to Figure 7 and Figure 8 As shown, the partition plate 4 has a first limiting structure 45, and the first lever 2 and / or the second lever 3 have a second limiting structure at the second end b. Figure 6 As shown, the first lever 2 has two second limiting structures 21 at the second end b, and the two second limiting structures 21 are located on both sides of the first lever 2 in the width direction.

[0101] Through the cooperation of the first limiting structure 45 and the second limiting structure 21, the second end of the first lever 2 can move relative to the partition 4 in the second direction (ie, the pressing direction), but cannot move relative to the partition 4 in the first direction (ie, the horizontal direction).

[0102] Since the second end b of the first lever 2 and the second end b of the second lever 3 are hinged, the second end b of the first lever 2 and the second end b of the second lever 3 move synchronously.

[0103] In one example, the first limiting structure 45 may be an opening, and the second limiting structure 21 may be a protrusion, for example, Figure 6 As shown, the first limiting structure 45 is a strip hole parallel to the second direction, and the second limiting structure 21 is a cylindrical protrusion. Alternatively, the first limiting structure 45 can also be a slot structure with a slot depth direction parallel to the second direction, and the slot of the slot structure faces the button 1.

[0104] The reason why the movement of the second end of the first lever 2 and the second end of the second lever 3 is limited in the first direction is to prevent the first lever 2 and the second lever 3, which have a hinged relationship, from moving left and right as a whole in the first direction when the button 1 is pressed. Once there is left and right movement, the first end of the first lever 2 and the first end of the second lever 3 will be subjected to uneven force.

[0105] In the disclosed embodiment, the button of the pressing mechanism is assembled with the partition through a first lever and a second lever having a hinged relationship, and the first ends of the first lever and the second lever that are away from each other have the same movement, such as synchronous upward or downward movement. Then, the first end of the first lever is abutted against the first side of the button, and the first end of the second lever is abutted against the second side of the button, so that the first side and the second side of the button can move synchronously relative to each other. Once the first side and the second side of the button move synchronously, the button can be kept parallel to the wall at all times during movement, thereby achieving pure flat movement of the button.

[0106] This embodiment also provides a push switch, which can be an electronic switch or a mechanical switch. Figures 1 to 5 As shown, the push switch includes a switch module 400, a reset mechanism 200, a base assembly 300 and the above-mentioned pressing mechanism 100, the switch module 400 is located in the base assembly 300, the reset mechanism 200 extends into the base assembly 300, and is used to drive the switch module 400 to perform a switch function, the pressing mechanism 100 covers and is assembled on the base assembly 300, and the button 1 of the pressing mechanism 100 abuts against the reset mechanism 200.

[0107] Among them, the characteristics of the push switch can be referred to above and will not be repeated here.

[0108] The above description is only a preferred embodiment of the present disclosure and is not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure should be included in the protection scope of the present disclosure.
