Claims (10)

1. A switching mechanism, comprising:

The mounting seat is provided with a mounting cavity, an outlet communicated with the mounting cavity and an inlet communicated with the mounting cavity;

The rotary switch comprises a rotary body and a switch body, wherein the rotary body is rotatably installed on the installation seat, the outlet of the installation seat faces towards the rotary body, the outlet of the installation seat faces away from the rotary body, the rotary body and the switch body have corresponding multiple states, and the rotary body rotates to enable the switch body to be switched between the multiple states;

The limiting piece is arranged in the mounting cavity;

At least one elastic member mounted to the mounting cavity; and

The sealing cover piece is arranged on the mounting seat to seal the inlet, one end of the elastic piece is abutted to the sealing cover piece, the other end of the elastic piece is abutted to the limiting piece, and the limiting piece stretches out of the outlet under the action of the elastic piece to be abutted to the rotating body.

2. The switch mechanism of claim 1, wherein the mounting base comprises a base body providing the mounting cavity and a first bracket protruding from the base body to form the inlet, and the cover member covers the first bracket to block the inlet and abuts against the elastic member.

3. The switch mechanism of claim 2, wherein the cover member includes an abutment portion and a connection portion, the connection portion is fixedly connected to the abutment portion, the first bracket includes a clamping frame body, the connection portion is clamped to the clamping frame body, and the abutment portion seals the inlet and abuts against the elastic member.

4. The switch mechanism of claim 3, wherein the cover further comprises a guide portion fixedly connected to the abutting portion, the guide portion and the connecting portion being located on the same side of the abutting portion, the first bracket includes a mating portion provided to the clamping frame body, and the mating portion extends from an end of the first bracket relatively far from the seat body toward the seat body;

When the sealing cover piece is covered on the first bracket, the guide part slides along the matching part to guide the connecting part to be clamped on the first bracket.

5. The switch mechanism of claim 3, wherein the cover further comprises a positioning portion, the positioning portion is located on a side of the abutting portion facing the first bracket, the first bracket further comprises a limiting portion disposed at an end of the clamping frame opposite to the base, and the positioning portion is clamped to the limiting portion.

6. The switch mechanism according to any one of claims 2 to 5, wherein the rotating body is provided with a convex portion and a concave portion, the convex portion and the concave portion respectively abut against the stopper when the rotating body rotates, the switch body has a first state and a second state, the stopper abuts against the convex portion when the switch body is in the first state, and the stopper abuts against the concave portion when the switch body is in the second state.

7. The switch mechanism of claim 2, further comprising a support table and a key switch, wherein the base is rotatably connected to the support table, and the key switch is fixedly connected to the support table, and when the rotating body is pressed, the rotating body drives the base to rotate, so that the base touches the key switch.

8. The switch mechanism of claim 7, further comprising a force-transmitting member and a triggering member, wherein the force-transmitting member is rotatably connected to the supporting table, the force-transmitting member has two ends far away from each other, the two ends of the force-transmitting member respectively abut against the base and the triggering member, the triggering member is slidably connected to the supporting table, a side of the triggering member relatively far away from the force-transmitting member abuts against the key switch, and the base rotates and drives the force-transmitting member to rotate, so that the triggering member triggers the key switch.

9. The switch mechanism of claim 8, wherein the housing defines a limiting slot, the limiting slot being located on a side of the housing opposite the force-transmitting member, and an end of the force-transmitting member opposite the housing being located within the limiting slot.

10. The switch mechanism as claimed in claim 9, wherein a relief slope is provided at an end of the force-transmitting member relatively close to the base, the relief slope facing toward a side of the limit groove relatively away from the support table, and a gap is always provided between the relief slope and the base when the force-transmitting member rotates.
