[0040] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0041] Please refer to Figure 1-Figure 6 The elastic seesaw 100 and the seesaw switch 1000 provided in the embodiment of the utility model can solve the above-mentioned problems, which will be described in detail below.

[0042] refer to Figure 1-Figure 3 The elastic seesaw 100 is used for a seesaw switch 1000, and the elastic seesaw 100 includes an elastic frame 110, a first contact 120, and a second contact 130; wherein the elastic frame 110 includes a first bent plate 111 and a second bent plate 112, and the first bent plate 111 and the second bent plate 112 enclose a hollow cavity 115, the first contact 120 is arranged on the first bent plate 111, and the second contact 130 is arranged on the second bent plate 112.

[0043] A driving fitting portion 116 is formed at one connection point between the first bent plate 111 and the second bent plate 112 , and a supporting portion 117 is formed at the other connection point. The supporting portion 117 is used to abut against the supporting member 300 , and the driving fitting portion 116 is used to abut against the pressing member 200 .

[0044] During operation, the elastic seesaw 100 can compress the hollow cavity 115 when subjected to external force, so that the first curved plate 111 and the second curved plate 112 are deformed and move. The first curved plate 111 and the second curved plate 112 are in an enclosed structure, which can withstand greater extrusion force and have a longer service life, thereby improving the on-off performance of the switch.

[0045] In addition, the first bent plate 111 and the second bent plate 112 can be made symmetrical about the line connecting the driving mating portion 116 to the supporting portion 117 ; the first contact 120 and the second contact 130 can also be made symmetrical about the line connecting the driving mating portion 116 to the supporting portion 117 .

[0046] When the driving mating portion 116 is subjected to an external force, the hollow cavity 115 can be compressed, and the first curved plate 111 and the second curved plate 112 can be driven to rotate with the contact position between the supporting portion 117 and the supporting member 300 as the fulcrum. Because the first curved plate 111 and the second curved plate 112 are symmetrical, the first contact point 120 and the second contact point 130 are symmetrical, the elastic deformation of the entire elastic frame 110 can be made more uniform, the contact stability of the two contacts is improved, and the on-off performance of the switch is improved.

[0047] It is worth noting that the first bent plate 111 and the second bent plate 112 may be an integrally formed bending structure, or may be formed into the elastic frame 110 by bonding or welding, and the specific forming method is not limited.

[0048] refer to Figure 3 In order to prevent the first bent plate 111 and the second bent plate 112 from breaking when elastic deformation occurs, the corners of the first bent plate 111 and the second bent plate 112 can be made arc-shaped to avoid cracks at the edges during the deformation process; at the same time, the first bent plate 111 and the second bent plate 112 can also have a better elastic potential energy storage effect.

[0049] Of course, under the premise that the first bent plate 111 and the second bent plate 112 have sufficient elasticity and toughness, there can also be edges and corners at the corners of the two, and there is no limitation on whether they are acute angles, right angles or obtuse angles.

[0050] refer to Figure 4 The first bent plate 111 defines a first mounting hole 1111, and the second bent plate 112 defines a second mounting hole 1121. The first mounting hole 1111 and the second mounting hole 1121 are symmetrical about a line connecting the driving mating portion 116 to the supporting portion 117. The first contact 120 is disposed in the first mounting hole 1111, and the second contact 130 is disposed in the second mounting hole 1121.

[0051] In the above technical solution, the first mounting hole 1111 and the second mounting hole 1121 are provided to facilitate the installation and accommodation of the first contact 120 and the second contact 130. When the contact is damaged and needs to be repaired or replaced, the contact can be directly taken out from the mounting hole, thereby improving the convenience of disassembly and assembly.

[0052] In this embodiment, the cross-sectional shapes of the first mounting hole 1111 and the second mounting hole 1121 are both circular; of course, in other embodiments of the present invention, the cross-sectional shapes of the first mounting hole 1111 and the second mounting hole 1121 can also be rectangular, triangular, prismatic, elliptical or other shapes, and the specific cross-sectional shapes are not limited.

[0053] refer to Figure 5 The first contact 120 includes a first fixing portion 121 and a first conducting portion 122 connected to each other, the first fixing portion 121 is accommodated in the first mounting hole 1111, and the cross-sectional size of the first conducting portion 122 is larger than the cross-sectional size of the first conducting portion 122; the second contact 130 includes a second fixing portion 131 and a second conducting portion 132 connected to each other, the second fixing portion 131 is accommodated in the second mounting hole 1121, and the cross-sectional size of the second conducting portion 132 is larger than the cross-sectional size of the second conducting portion 132.

[0054] In the above technical solution, by providing the first conducting part 122 and the second conducting part 132 with larger cross-sectional dimensions, the contact area of ​​the contact point can be increased, thereby improving the contact stability.

[0055] In this embodiment, the cross-sectional shapes of the first fixing portion 121 and the second fixing portion 131 are adapted to the cross-sectional shapes of the first mounting hole 1111 and the second mounting hole 1121 and are both circular. When the cross-sectional shapes of the first mounting hole 1111 and the second mounting hole 1121 are adjusted, the cross-sectional shapes of the first fixing portion 121 and the second fixing portion 131 can be adaptively adjusted.

[0056] Specifically, the first fixing portion 121 and the first mounting hole 1111, and the second fixing portion 131 and the second mounting hole 1121 may be interference fit; the first fixing portion 121 and the first mounting hole 1111, and the second fixing portion 131 and the second mounting hole 1121 may be connected by a snap fit; the first fixing portion 121 and the first mounting hole 1111, and the second fixing portion 131 and the second mounting hole 1121 may be connected by a threaded connection, that is, the outer walls of the first fixing portion 121 and the second fixing portion 131 are provided with external threads, and the inner walls of the first mounting hole 1111 and the second mounting hole 1121 are provided with internal threads.

[0057] In this embodiment, the cross-sectional shape of the first conduction portion 122 and the second conduction portion 132 is also circular; of course, in other embodiments of the present invention, the cross-sectional shape of the first conduction portion 122 and the second conduction portion 132 can also be other shapes such as rectangle, triangle, prism, ellipse, etc., and the specific cross-sectional shape is not limited.

[0058] refer to Figure 3When the first bent plate 111 and the second bent plate 112 are deformed, in order to prevent the contact points from being affected and deformed, the thickness of the first fixed portion 121 and the first conductive portion 122 can be made greater than the thickness of the first bent plate 111, and the thickness of the second fixed portion 131 and the second conductive portion 132 can be made greater than the thickness of the second bent plate 112, thereby ensuring that the first contact 120 and the second contact 130 have sufficient structural strength to avoid deformation along with the first bent plate 111 and the second bent plate 112 when subjected to external force during the contact process.

[0059] refer to Figure 3 One of the connections between the first bent plate 111 and the second bent plate 112 extends toward the direction close to the hollow cavity 115 to form a driving mating portion 116, and the driving mating portion 116 is in an arc shape toward the support member 300, so that the driving mating portion 116 is a recessed structure on the elastic frame 110, and the recessed direction is consistent with the direction from the pressing member 200 to the support member 300, so that the driving mating portion 116 can better resist the pressing member 200 to drive the elastic frame 110 to rotate.

[0060] One of the connections between the first bent plate 111 and the second bent plate 112 extends in a direction away from the hollow cavity 115 to form a supporting portion 117, so that the supporting portion 117 is a protruding structure on the elastic frame 110, so that the supporting portion 117 can better support the support member 300 during the rotation of the elastic frame 110.

[0061] In addition, the support portion 117 has a double-layer structure and is formed by overlapping the end of the first bent plate 111 and the end of the second bent plate 112, that is, the first bent plate 111 and the second bent plate 112 are single-layer structures in other parts, so that the structural thickness of the support portion 117 is thicker, which can ensure that the support portion 117 has sufficient structural strength to support the support member 300.

[0062] refer to Figure 3 A protrusion 1171 is provided on the support portion 117, and the protrusion 1171 is used to be accommodated in the accommodating hole 320 of the support member 300. The cooperation between the protrusion 1171 and the accommodating hole 320 can prevent the support portion 117 from easily detaching from the support member 300 during the swinging process, thereby improving the swinging stability of the elastic seesaw 100.

[0063] refer to Figure 1-Figure 3The embodiment of the utility model further provides a rocker switch 1000, which includes a pressing member 200, a first terminal 400, a second terminal 500, a supporting member 300 and an elastic rocker 100; wherein the pressing member 200 and the supporting member 300 are respectively abutted against two connection points of the first bent plate 111 and the second bent plate 112, the first terminal 400 is provided with a third contact 410, and the second terminal 500 is provided with a fourth contact 510, and the pressing member 200 is used to drive the first bent plate 111 and the second bent plate 112 to swing with the supporting member 300 as a fulcrum under the action of an external force, so that the first contact 120 contacts the third contact 410, or the second contact 130 contacts the fourth contact 510.

[0064] Specifically, the pressing member 200 abuts against the driving matching portion 116 , and the supporting member 300 abuts against the supporting portion 117 .

[0065] When it is necessary to adjust the on / off state of the rocker switch 1000, the user can apply force to the pressing member 200 so that one side of the pressing member 200 is pressed down and the other side is tilted up. During the movement, the pressing member 200 will drive the elastic rocker 100 to swing, so that the first contact 120 is in contact with the third contact 410, and the second contact 130 is separated from the fourth contact 510; when the other side of the pressing member 200 is pressed, the second contact 130 is in contact with the fourth contact 510, and the first contact 120 is separated from the third contact 410, thereby realizing the on / off state adjustment of the rocker switch 1000.

[0066] It is worth noting that the structures of the third contact 410 and the fourth contact 510 can be similar to those of the first contact 120 and the second contact 130, so that the stability during contact is better. In addition, the support member 300 is always against the support portion 117. When the contacts are in contact, the signal can be transmitted from the outgoing contacts to the elastic frame 110 and then to the support member 300.

[0067] In this embodiment, the pressing member 200 is a T-shaped structure, which includes a pressing portion 210 located on the upper side and a transmission portion 220 located on the lower side, and the transmission portion 220 is used to cooperate with the driving matching portion 116 of the elastic seesaw 100. From the perspective of improving transmission efficiency, the transmission portion 220 is in the shape of a cone head, and the driving matching portion 116 is in the shape of a groove. When the cone head is deflected, the side wall can contact the side wall of the groove to drive the entire elastic seesaw 100 to swing.

[0068] refer to Figure 6 The support member 300 is provided with a recessed portion 310, and the support portion 117 is accommodated in the recessed portion 310 and rotatably cooperates with the recessed portion 310; and the recessed portion 310 is provided with a receiving hole 320, so that the protrusion on the support portion 117 can be accommodated in the receiving hole 320, thereby stably supporting the support portion 117.

[0069] In summary, the elastic seesaw 100 and the seesaw switch 1000 provided by the embodiments of the present invention have at least the following advantages:

[0070] (1) The rocker switch 1000 can utilize the elasticity and toughness of the elastic frame 110 to generate elastic deformation during the activity to store elastic potential energy to realize the on-off action. No spring or ball is required, which can reduce the number of components and thus achieve the purpose of reducing manufacturing cost and maintenance cost.

[0071] (2) The rocker switch 1000 installs the first contact 120 and the second contact 130 on the first bent plate 111 and the second bent plate 112 respectively, so that the contact with the third contact 410 and the fourth contact 510 is non-rigid contact, which can reduce contact bounce and thus improve the on-off performance of the switch.

[0072] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
