Automatic power transfer switching mechanism
First Claim
1. An automatic power transfer switching mechanism for selectively connecting a first power supply or a second power supply to an electrical network, comprising:
- a frame;
a first power switch configured to connect or disconnect the first power supply to the electrical network;
a second power switch configured to connect or disconnect the second power supply to the electrical network;
a push member rotatably disposed on the frame and rotatable with respect to a first axis, wherein the push member comprises a first push portion and a second push portion, and the first axis is located between the first push portion and the second push portion;
a linking mechanism connected to the push member; and
a first driving source connected to the linking mechanism and rotating the push member about the first axis so as to move the first push portion to push the first power switch along a first direction and move the second push portion to push the second power switch along a second direction opposite to the first direction;
wherein the linking mechanism comprises;
a first linking member rotatably connected to the push member;
a second linking member rotatably connected to the first linking member, wherein the first driving source is connected to the second linking member and rotates the second linking member about a second axis so that the first linking member moves the push member to rotate the push member about the first axis; and
wherein the second linking member comprises an eccentric wheel on which the first linking member rotatably holds, a center of the eccentric wheel is spaced from the second axis, and the first driving source rotates the eccentric wheel about the second axis.

Abstract
An automatic power transfer switching mechanism includes several links and a push member. The links move to rotate the push member. The push member has two push portions configured to push two power switches. The push member is rotatable about a first axis located between the two push portions so that when one of the push portion moves forwards, the other push portion moves backwards. Therefore, when one push portion moves forward to push one power switch on, the other push portion moves backwards to simultaneously push the other power switch off. The power transfer can be switched automatically without delay.

-
a frame; a first power switch configured to connect or disconnect the first power supply to the electrical network; a second power switch configured to connect or disconnect the second power supply to the electrical network; a push member rotatably disposed on the frame and rotatable with respect to a first axis, wherein the push member comprises a first push portion and a second push portion, and the first axis is located between the first push portion and the second push portion; a linking mechanism connected to the push member; and a first driving source connected to the linking mechanism and rotating the push member about the first axis so as to move the first push portion to push the first power switch along a first direction and move the second push portion to push the second power switch along a second direction opposite to the first direction; and an indicating member comprising a first indicating end corresponding to the first push portion and a second indicating end corresponding to the second push portion, wherein the indicating member is fixed to the push member so that the indicating member is rotatable about the first axis along with the push member simultaneously;
the first indicating end protrudes from the frame and the second indicating end is hidden in the frame when the first push portion pushes the first power switch to switch the first power supply on;
the second indicating end protrudes from the frame and the first indicating end is hidden in the frame when the second push portion pushes the second power switch to switch the second power supply on.- View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19)
