Referring to fig. 1 to 6, an embodiment of the present invention provides a switch activation structure, which includes a movable element 100, an activation element 200, and a structural element 300. When the switch starting structure is used, the movable element 100 can be moved by pressing or the like, the movable element 100 can drive the starting element 200 to move, and the starting element 200 can drive the structural element 300 to move when moving, so that the electrical structure 310 arranged on the starting element 200 is opened or closed, and the switch is turned on or turned off.

As shown in fig. 1-3, one of the movable element 100 and the starting element 200 is provided with at least two abutting structures 400, and the other of the movable element 100 and the starting element 200 is provided with at least two pressing structures 500. The number of the pressing structures 500 is equal to the number of the abutting structures 400, and the pressing structures correspond to the abutting structures one by one. As shown in fig. 5 and 6, when the movable element 100 is located at the first position, each pressing structure 500 is abutted against the corresponding abutting structure 400 to drive the structural element 300 to move to the open position.

For example, in some embodiments, the moveable member 100 is provided with the pressing structure 500 and the activation member 200 is provided with the interference structure 400. When the movable member 100 is located at the first position, the abutting structure 400 abuts against the pressing structure 500.

For another example, in other embodiments, the moveable element 100 is provided with the abutting structure 400, and the starting device 200 is provided with the pressing structure 500, and when the moveable element 100 is located at the first position, the abutting structure 400 abuts against the pressing structure 500.

Through the above arrangement, when the moving part 100 moves to the first position, each pressing structure 500 of the moving part 100 is all inconsistent with the corresponding conflict structure 400, so that the starting part 200 has at least two action points stressed when moving, the instantaneous speed of the starting part 200 is accelerated, the starting part 200 can be driven quickly, and further the structure 300 moves to the corresponding position, the electrical structure 310 of the structure 300 changes state quickly, and the electric arc generated when the electrical structure 310 changes state is reduced. That is, when the movable element 100 moves to the first position, each interference structure 400 of the starting element 200 is pressed by the corresponding pressing structure 500, and the pressing force is multiplied compared to the conventional method, so as to have a higher instantaneous speed.

The movable element 100 is connected to the starting element 200, and the movable element 100 and the starting element 200 rotate coaxially. In some embodiments, the activation member 200 is provided with a rotation protrusion 210, the mover 100 is provided with a receiving hole 110, and the rotation protrusion 210 is located in the receiving hole 110. The axis of the rotating protrusion 210 is the rotating axis of the movable element 100 and the actuating element 200.

The side of the starting member 200 away from the moving member 100 is provided with a mounting portion 220, and the mounting portion 220 is provided with a mounting groove 221. Portions of the structural member 300 are received in the mounting grooves 221. In some embodiments, the mounting groove 221 is provided with a resilient member 222, such as a spring. The spring is positioned in the mounting groove 221, and the structural member 300 is received in the spring. One end of the structural member 300 away from the mounting groove 221 is used for movably connecting with a switch or a socket. That is, the structure member 300 can rotate along an end thereof away from the mounting groove 221 as a rotation axis. The structure 300 is provided with an electrical structure 310, which electrical structure 310 may be selected from the prior art.

When the movable element 100 moves to the first position under the action of an external force, the movable element 100 drives the starting element 200 to move, and when the starting element 200 moves, the structural element 300 located in the mounting groove 221 is driven to rotate, so that the state of the electrical structure 310 is changed.

The cross-sectional shape of the actuator 200 may be similar to Ω as shown in fig. 5 and 6, may be similar to straight line, or may have another shape. The shape may be axisymmetric or non-axisymmetric. The shape of the actuator 200 can be adjusted according to the actual situation.

The following description will take an example in which the movable member 100 is provided with the pressing structure 500, and the activation member 200 is provided with the interference structure 400.

In some embodiments, the pressing structure 500 includes a central pressing structure 510 and at least one edge pressing structure 520. Center pressing structure 510 is disposed in the middle of moveable member 100, and each edge pressing structure 520 is disposed in a position away from the centerline of moveable member 100. Correspondingly, the interference structure 400 includes a central interference structure 410 and at least one edge interference structure 420. Wherein the central interference structure 410 is located at the middle of the actuating member 200, and the edge interference structures 420 are all disposed at positions of the actuating member 200 away from the central line.

When the movable member 100 is located at the first position, the central abutting structure 410 abuts against the central pressing structure 510, and the edge pressing structures 520 abut against the corresponding edge abutting structures 420.

It should be noted that there may be a gap between the central interference structure 410 and the central pressing structure 510, or the interference state may be maintained all the time. The edge interference structure 420 and the edge pressing structure 520 may have a gap therebetween, or may always maintain an interference state.

That is, when the movable element 100 is in the first position, the central abutting structure 410 abuts against the central pressing structure 510; when the movable member 100 is located at the second position (the electrical structure 310 of the structural member 300 is driven to the other state), the central abutting structure 410 and the central pressing structure 510 may abut or have a gap. When the central abutting structure 410 and the central pressing structure 510 always maintain the abutting position, the time for the moving member 100 to drive the starting member 200 to move can be reduced, and the electric arc can be effectively reduced. Similarly, when mover 100 is in the first position, edge interference structure 420 interferes with edge pressing structure 520; when the movable member 100 is located at the second position, the edge abutting structure 420 and the edge pressing structure 520 may abut or have a gap.
