[0002] A dual power automatic transfer switch is a device that can reliably switch between two power sources. It consists of one or more transfer switch appliances and other necessary appliances, and is used to detect power circuits and automatically switch one or more load circuits from one power source to another.

[0003] In some prior arts, a V-shaped groove is provided to realize the switching between the normal power supply position and the standby power supply position. Such a design has the problem of a long switching stroke, which leads to a long switching time.

[0004] In summary, there is currently a lack of a switching structure to improve or partially improve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to overcome the defects of the prior art and provide a transmission push plate of a dual power switch, which improves the problem of long switching stroke by changing the position of the rotating shaft by adopting an arc waist hole.

[0037] Example 1

[0038] In view of the above-mentioned problems, this embodiment provides a push plate structure for a three-stage dual power conversion switch, see Figure 1 and Figure 2 , the structure includes:

[0039] The first plate body 1 has a first arc-shaped waist hole.

[0040] The common rotating shaft 2 cooperates with the first arc-shaped waist hole and abuts against the inner wall of the first arc-shaped waist hole.

[0041] The second plate body 3 has a second arc-shaped waist hole, and the inner wall of the second arc-shaped waist hole is abutted. With the perpendicular midline of the line connecting the first arc-shaped waist hole and the second arc-shaped waist hole as a reference, the first plate body 1 and the second plate body 3 are symmetrically arranged, and the cross-sections of the first arc-shaped waist hole and the second arc-shaped waist hole are symmetrical. And the relative positions of the first plate body 1 and the second plate body 3 are fixed.

[0042] The spare rotating shaft 4 cooperates with the second arc-shaped waist hole, and the cross sections of the common rotating shaft 2 and the spare rotating shaft 4 are both circular.

[0043] By adopting the above design, Figure 1 Take the first plate body 1 in the example, when it is installed on the mechanism, the first plate body 1 is forced to do linear motion. When pushed to the right, the common rotating shaft 2 installed in the arc groove is pushed, and the inner circle of the arc curve pushes the common rotating shaft 2 to do counterclockwise motion. With very little force, the connecting rod can be pushed to rotate, and the rotational motion is very flexible to convert the linear motion and the linear motion to the rotational motion. When pushed to the left, the common rotating shaft 2 installed in the arc groove is pushed, and the outer circle of the arc curve pushes the common rotating shaft 2 to do clockwise motion, and the connecting rod can be pushed to rotate with very little force.

[0044] See also Figure 3 , Figure 4 and Figure 5 , by pushing the plate body to realize the rotation of the shaft, and then realize the subsequent opening and closing functions, the first plate body 1 and the second plate body 3 are L-shaped, see Figure 2 An electromagnet 5 and a return spring 6 are arranged between the first plate body 1 and the extension section of the second plate body 3 , and a return spring 6 is arranged between the second plate body 3 and the electromagnet 5 and between the first plate body 1 and the electromagnet 5 .

[0045] Through the above arrangement, the first plate 1 and the second plate 3 can be driven inward by stimulating the electromagnet 5, thereby changing the position of the rotating shaft and realizing the state switching of the common switch and the standby switch. After the electromagnet 5 loses power, the reset spring 6 can be used to return to its original position.

[0046] When the first plate body 1 moves, the common rotating shaft 2 is rotated to realize the movement in the first arc-shaped waist hole. When the second plate body 3 moves, the spare rotating shaft 4 is rotated to realize the movement in the second arc-shaped waist hole.

[0047] This structure uses a push plate to drive the common and standby positions. The common power supply and the standby power supply are driven separately. Two symmetrical independent plates are used, including a push plate for the common power supply and a plate for the standby power supply. The plate shape is L-shaped.

[0048] The principle of converting linear motion into rotational motion is as follows: the plate is driven by an electromagnet to perform linear motion, and the push groove on the plate adopts an arc curve structure to drive the rotating shaft to rotate. The arc curve motion increases the torque of the rotating shaft and reduces the resistance to linear motion. Compared with straight grooves and inclined grooves, the same force can be used to push the plate's linear motion to output the force to rotational motion, and the force of the arc curve is much greater.

[0049] Example 2

[0050] Based on Example 1, see Figure 6 This embodiment provides a push plate structure for a two-stage dual power conversion switch. Compared with the first embodiment, the difference of this embodiment is that the first plate body 1 and the second plate body 3 are integrally formed.

[0051] See also Figure 7 , Figure 8 and Fig. 9 In this embodiment, the first plate body 1 and the second plate body 3 are directly connected.

[0052] In the two-stage switch, the push plates of the normal power supply and the standby power supply are composed of a whole, and the push plate is U-shaped.

[0053] Since the design of the plate in the two-stage switch allows the common power supply and the backup power supply to move simultaneously, compared with the V-groove, the force loss during the conversion process is smaller and the conversion stroke is much shorter, so the conversion time is very fast. Taking the two-stage switch as an example, the conversion time of the general V-groove is about 70ms, while the conversion time of the push plate can be within 20ms.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements 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.
