Abstract

The present invention relates to a mechanical operating assembly for a bistable relay and a bistable relay assembly. The mechanical operating assembly comprises: an actuating mechanism mounted to a bracket, including an actuating member and a first transmitting member which is connected to a paddle, the actuating member is movable between an initial position in which the actuating member is not in contact with the first transmitting member and an actuating position, when the actuating member moves from the initial position to the actuating position, the actuating member contacts the first transmitting member; a reset mechanism mounted to the bracket, including a reset member and a second transmitting member which is in contact with the first transmitting member, the reset member is movable between an initial position and a reset position, the reset member contacts the second transmitting member when moving from the initial position to the reset position.

First claim

The invention claimed is:

1. A mechanical operating assembly for a bistable relay, wherein the mechanical operating assembly comprises:
a bracket being mounted to the bistable relay;
an actuating mechanism being mounted to the bracket, including an actuating member and a first transmitting member, wherein the first transmitting member is connected to a paddle of the bistable relay, and the actuating member is configured to move the first transmitting member when actuated, thereby moving the paddle of the bistable relay, such that the bistable relay is switched from a first state to a second state;
a reset mechanism being mounted to the bracket, including a reset member and a second transmitting member, wherein the second transmitting member is in contact with the first transmitting member, and the reset member is movable between an initial position in which the reset member is not in contact with the second transmitting member, and a reset position, wherein when the reset member moves from the initial position to the reset position, the reset member is configured to contact the second transmitting member, so that the second transmitting member moves correspondingly, and the first transmitting member drives the paddle of the bistable relay to move, such that the bistable relay is switched from the second state to the first state, and wherein after the reset member reaches the reset position, the reset member is configured to be out of contact with the second transmitting member.

2. A mechanical operating assembly according to claim 1 , wherein the actuating member is movable between the initial position in which the actuating member is not in contact with the first transmitting member, and an actuating position, wherein, when the actuating member moves from the initial position to the actuating position, the actuating member is configured to be in contact with the first transmitting member, so that the first transmitting member drives the paddles of the bistable relay to move to switch the bistable relay from the first state to the second state.

3. A mechanical operating assembly according to claim 2 , wherein the first transmitting member is mounted on the bracket in a translation manner, wherein the actuating member includes a first inclined surface, and the first transmitting member includes a second inclined surface, wherein when the actuating member moves from the initial position to the actuating position, the first inclined surface abuts against the second inclined surface and pushes the first transmitting member in a first translation direction to switch the bistable relay from the first state to the second state.

4. A mechanical operating assembly according to claim 3 , wherein the actuating mechanism further includes a first reset spring, which is provided between the actuating member and the bracket, wherein after the actuating member overcomes the elastic force of the first reset spring and moves from the initial position to the actuating position, the actuating member is configured to return to its initial position through the elastic force of the first reset spring.

5. A mechanical operating assembly according to claim 3 , wherein the first transmitting member further includes an indicator, and after the first transmitting member translates in a horizontal direction to switch the bistable relay from the first state to the second state, the indicator is exposed through a window in a housing to indicate that the bistable relay is in the second state, said housing surrounding the bistable relay and the mechanical operating assembly.

6. A mechanical operating assembly according to claim 3 , wherein the reset member includes a first matching member, wherein the second transmitting member is rotatably mounted on the bracket, and includes a second matching member, wherein when the reset member moves from the initial position to the reset position, the first matching member abuts against the second matching member and pushes the second transmitting member to rotate in the first direction, such that the first transmitting member moves in a second translation direction opposite to the first translation direction, causing the bistable relay to switch from the second state to the first state.

7. A mechanical operating assembly according to claim 6 , wherein the first matching member includes a third inclined surface, and when the reset member moves from the initial position to the reset position, the third inclined surface abuts against the second matching member and pushes the second transmitting member to rotate in the first direction.

8. A mechanical operating assembly according to claim 7 , wherein the reset mechanism further includes a second reset spring, which is disposed between the second transmitting member and the bracket; and a third reset spring which is disposed between the reset member and the bracket, wherein when the reset member overcomes the elastic force of the third reset spring and moves from the initial position to the reset position, the second transmitting member overcomes the elastic force of the second reset spring and rotates in the first direction.

9. A mechanical operating assembly according to claim 8 , wherein after the reset member reaches the reset position, the third inclined surface is configured to disengage from abutment with the second matching member, and the second transmitting member is configured to return to its initial position under the action of the second reset spring.

10. A mechanical operating assembly according to claim 9 , wherein the reset mechanism further includes a third reset spring, which is disposed between the reset member and the bracket, wherein after the reset member reaches the reset position, the reset member is configured to return to its initial position through the third reset spring.

11. A mechanical operating assembly according to claim 10 , wherein the first matching member further includes a curved surface opposite to the third inclined surface, wherein during the process that the reset member returns to its initial position through the third reset spring, the second matching member of the second transmitting member moves to the initial position along the curved surface.

12. A mechanical operating assembly according to claim 2 , wherein the first transmitting member is rotatably mounted on the bracket, wherein when the actuating member moves from the initial position to the actuating position, the actuating member is configured to abut against the first transmitting member to rotate the first transmitting member, thereby driving the bistable relay to switch from the first state to the second state.

13. A bistable relay assembly, comprising a bistable relay and the mechanical operating assembly according to claim 1 .
