In other words, the first micro switch button 121 and the second micro switch button 131 may be switched-on-triggered or switched-off-triggered. The specific implementation will be described in detail below.
Referring to Figs. 2 and 6, the state indicating module 100 according to the present utility model may further include a transmission assembly, and the transmission assembly may include a first transmission assembly 140 and a second transmission assembly 150.

Each state indicating module 100 can output a set of on and off information of the automatic transfer switching equipment 1.
The specific structure of the state indicating module 100 according to the first embodiment and the second embodiment of the present utility model will be described in detail below with reference to the accompanying drawings.

<First embodiment

Fig. 2 is an exploded perspective view showing the part of the automatic transfer switching equipment 1 and the structure of the state indicating module according to a first embodiment of the present utility model 100, viewed from below. Referring to Fig. 2, the first transmission assembly 140 of the state indicating module 100 according to the first embodiment of the present utility model may include a first pushing rod 141. The first pushing rod 141 extends along the driving direction of the first lower driving rod 202 on the plane of the first lower driving rod 202 (seen more clearly in Figs. 3-5), is linearly movably mounted to the housing 110 in the extending direction, and includes a first protrusion 1411 protruding upward from the rod body of the first pushing rod 141. The end of the first pushing rod 141 adjacent to the first lower driving rod 202 has an arc shape, so that a linear end of the first lower driving rod 202 is convenient to contact with the arc end of the first pushing rod 141, and transmit the linear movement of the lower driving rod 202 to the first pushing rod 141, pushing the first pushing rod 141 to perform linear movement. The first transmission assembly 140 of the state indicating module 100 according to the first embodiment of the present utility model may further include a first oscillating rod 142, which is rotatably mounted to the housing 110 about a rotation axis. The first oscillating rod 142 may include a first actuating portion 1421 extending outward from the rod body of the first oscillating rod 142. The first actuating portion 1421 is configured to actuate the first micro switch button 121 when the first oscillating rod 142 is in the actuating position and to release the first micro switch button 121 when the first oscillating rod 142 is in the initial position. The rotation axis of the first oscillating rod 142 is perpendicular to the extending direction of the first pushing rod 141. The first transmission assembly 140 of the state indicating module 100 according to the first embodiment of the present utility model may further include a first return spring 143 configured to act on the first oscillating rod 142 with a return elastic force. As shown in Fig. 2, the first return spring 143 according to the first embodiment of the present utility model is a torsion spring, and is configured to apply an elastic force to the first oscillating rod 142 to restore it to the initial position.
The structure of the second transmission assembly 150 of the state indicating module 100 according to the first embodiment of the present utility model is similar to that of the first transmission assembly 140, and includes: a second pushing rod 151, which extends along the driving direction of the second upper driving rod 203 on the plane of the second upper driving rod 203, is linearly movably mounted to the housing 110 in the extending direction, and includes a second protrusion 1511 protruding upward from the rod body of the second pushing rod 151; a second oscillating rod 152, which is rotatably mounted to the housing 110 around a rotation axis, and includes a second actuating portion 1521 extending outward from the rod body of the second oscillating rod 152, the rotation axis of the second oscillating rod 152 is perpendicular to the extending direction of the second pushing rod 151; and a second return spring 153, which is configured to act on the second oscillating rod 152 with a return elastic force. It will not be described in detail here.
The principle of the state indicating module 100 according to the first embodiment of the present utility model will be described below with reference to Figs. 3-5.
Referring first to Figure 3, the first power supply and the second power supply are both switched off at this time, so the first upper driving rod 201 and the second lower driving rod 204 are in the driving position, and the first lower driving rod 202 and the second upper driving rod 203 are in the initial position. Since the first pushing rod 141 extends along the driving direction of the first lower driving rod 202 on the plane of the first lower driving rod 202, that is, aligned with the first lower driving rod 202, and the first lower driving rod 202 is in the initial position, the first pushing rod 141 is not pushed and is in the initial position, so that the first oscillating rod 142 and the first actuating portion 1421 thereon are also in the initial position, and thereby the first micro switch button 121 is in the released position, outputting a signal indicating the first power supply is switched off. In the same way, since the second pushing rod 151 extends along the driving direction of the second upper driving rod 203 on the plane of the second upper driving rod 203, that is, aligned with the second upper driving rod 203, and the second upper driving rod 203 is in the initial position, the second pushing rod 151 is not pushed and is in the initial position, so that the second oscillating rod 152 and the second actuating portion 1521 thereon are also in the initial position, and thereby the second micro switch button 131 is in the released position, outputting a signal indicating the second power supply is switched off.
Referring to Fig. 4 from Fig. 3, the first power supply transfers from switched off to switched on at this time, so the first lower driving rod 202 moves from the initial position to the driving position. At the same time, the first lower driving rod 202 contacts and drives the first pushing rod 141 aligned with the first lower driving rod 202 to move linearly, the first protrusion 1411 on the first pushing rod 141 contacts and drives the first oscillating rod 142 to rotate, and the first actuating portion 1421 on the first oscillating rod 142 actuates the first micro switch button 121 to the triggered position where the first micro switch button 121 is depressed, outputting a signal indicating the first power supply is switched on. In addition, since the second power supply is still off and the second upper driving rod 203 is still in the initial position, the second micro switch button 131 is not actuated, outputting a signal indicating the second power supply is switched off.
Referring to Fig. 5 from Fig. 4, the second power supply transfers from switched off to switched on at this time, so the second upper driving rod 203 moves from the initial position to the driving position. At the same time, the second upper driving rod 203 contacts and drives the second pushing rod 151 aligned with the second upper driving rod 203 to move linearly, the second protrusion 1511 on the second pushing rod 151 contacts and drives the second oscillating rod 152 to rotate, and the second actuating portion 1521 on the second oscillating rod 152 actuates the second micro switch button 131 to the triggered position where the second micro switch button 151 is depressed, outputting a signal indicating the second power supply is switched on. In addition, since the first power supply transfers from switched on to switched off, the first lower driving rod 202 moves from the driving position back to the initial position, and the first oscillating rod 142 returns to the initial position under the action of elastic force of the first return spring 143 thereby bringing the first pushing rod 141 to return to the initial position through the first protrusion 1411 where the first micro switch button 121 is released and returns to the released position under the action of its return force, outputting a signal indicating the first power supply is switched off.
Referring back to Fig. 3 from Fig. 5, when the second power supply transfers from switched on to switched off, the second upper driving rod 203 moves from the driving position back to the initial position, and the second oscillating rod 152 returns to the initial position under the action of elastic force of the second return spring 153 thereby bringing the second pushing rod 151 to return to the initial position through the second protrusion 1511 where the second micro switch button 131 is released and returns to the released position under the action of its return force, outputting a signal indicating the second power supply is switched off. In addition, since the first power supply is still off and the first lower driving rod 202 is still in the initial position, the first micro switch button 121 is not actuated, outputting a signal indicating the first power supply is switched off.
Because the first micro switch button 121 is in the released position when the first power supply is switched off, and the first micro switch button 121 is in the triggered position when the first power supply is switched on; the second micro switch button 131 is in the released position when the second power supply is switched off and the second micro switch button 131 is in the triggered position when the second power supply is switched on, the state indicating module 100 according to the first embodiment is switched-on-triggered.

Fig. 6 is an exploded perspective view showing the part of the power automatic transfer switch and the structure of the state indicating module 100 according to a second embodiment of the present utility model, viewed from below. Referring to Fig. 6, the first transmission assembly 140 of the state indicating module 100 according to the second embodiment of the present utility model may include a first pushing rod 141. The first pushing rod 141 extends along the driving direction of the second lower driving rod 204 on the plane of the second lower driving rod 204 (seen more clearly in Figs. 7-9) and linearly movably mounted to the housing 110 in the extending direction. The end of the first pushing rod 141 adjacent to the first lower driving rod 202 has an arc shape, so that the linear end of the first lower driving rod 202 is convenient to contact with the arc end of the first pushing rod 141, and transmit the linear movement of the first lower driving rod 202 to the first pushing rod 141, pushing the first pushing rod 141 to perform linear movement. The first pushing rod 141 includes a first protrusion 1411 protruding downward from the rod body of the first pushing rod 141, and the first protrusion 1411 includes a slope surface. The first transmission assembly 140 of the state indicating module 100 according to the second embodiment of the present utility model may further include a first sliding member 144 that is linearly movably mounted to the housing 110 in the up and down direction. The first sliding member 144 includes a slope surface that cooperates with the slope surface of the first protrusion 1411 of the first pushing rod 141, so that the linear movement of the first pushing rod 141 in its extension direction can be converted into the linear movement of the first sliding member 144 in the up and down direction. The first sliding member 144 further includes a first actuating portion 1421 configured to actuate the first micro switch button 121. The first transmission assembly 140 of the state indicating module 100 according to the second embodiment of the present utility model may further include a first return spring 143 configured to act on the first pushing rod 141 with a return elastic force. As shown in Fig. 6, the first return spring 143 according to the second embodiment of the present utility model is a compressed spring and is configured to apply an elastic force to the first pushing rod 141 to restore it to the initial position.
The structure of the second transmission assembly 150 of the state indicating module 100 according to the second embodiment of the present utility model is similar to that of the first transmission assembly 140, and includes: a second pushing rod 151 extending along a driving direction of the first upper driving rod 201 on a plane of the first upper driving rod 201, linearly movably mounted to the housing 110 in the extending direction, and including a second protrusion 1511 downwardly protruding from the rod body of the first pushing rod 141, the second protrusion 1511 including a slope surface; a second sliding member 154 linearly movably mounted to the housing 110 in the up and down direction, including an slope surface cooperating with the slope surface of the second protrusion 1511 so that the linear movement of the second pushing rod 151 in its extending direction can be converted to a linear movement of the second sliding member 1554 in the up and down direction, and further including a second actuating portion 1521 configured to actuate the second micro switch button 131; and a second return spring 153 configured to act a return elastic force on the second pushing rod 151. It will not be described in detail here.
It should be noted that, compared with the first embodiment, the relative position of the first transmission assembly 140 and the second transmission assembly 150 according to the second embodiment is opposite, and relative position of the first micro switch assembly 120 and the second transmission assembly 130 according to the second embodiment is also opposite.
The principle of the state indicating module 100 according to the second embodiment of the present utility model will be described below with reference to Figs. 7-9.
Referring first to Figure 7, the first power supply and the second power supply are both switched off at this time, so the first upper driving rod 201 and the second lower driving rod 204 are in the driving position, and the first lower driving rod 202 and the second upper driving rod 203 are in the initial position. Since the first pushing rod 141 extends along the driving direction of the second lower driving rod 204 on the plane of the second lower driving rod 204, that is, aligned with the second lower driving rod 204, and the second lower driving rod 204 is in the driving position, the first pushing rod 141 is pushed to the actuating position, so that the first sliding member 144 is pushed by the first pushing rod 141 to move downwardly to the actuating position through the cooperation of the slope surface of the first protrusion 1411 and the slope surface of the first sliding member 144, the first actuating portion 1421 of the first sliding member 144 is also in the actuating position, and thereby the first micro switch button 121 is in the triggering position, outputting a signal indicating the first power supply is switched off. In the same way, since the second pushing rod 151 extends along the driving direction of the first upper driving rod 201 on the plane of the first upper driving rod 201, that is, aligned with the first upper driving rod 201, and the first upper driving rod 201 is in the actuating position, the second pushing rod 151 is pushed to the actuating position, so that the second sliding member 154 is pushed by the second pushing rod 151 to move downwardly to the actuating position through the cooperation of the slope surface of the second protrusion 1511 and the slope surface of the second sliding member 154, the second actuating portion 1521 of the second sliding member 154 is also in the actuating position, and thereby the second micro switch button 131 is in the triggering position, outputting a signal indicating the second power supply is switched off.
Referring to Fig. 8 from Fig. 7, the first power supply transfers from switched off to switched on at this time, so the second lower driving rod 204 moves from the driving position back to the initial position. The first pushing rod 141 returns to the initial position under the action of the elastic force of the first return spring 143, and the first micro switch button 121 and the first sliding member 144 return to the released position and the initial position respectively under the action of the return force of the first micro switch button 121, outputting a signal indicating the first power supply is switched on. In addition, since the second power supply is still off and the first upper driving rod 201 is still in the driving position, the second micro switch button 131 is still actuated and is in the triggered position, outputting a signal indicating the second power supply is switched off.
Referring to Fig. 9 from Fig. 8, the second power supply transfers from switched off to switched on at this time, so the first upper driving rod 201 moves from the driving position back to the initial position. The second pushing rod 151 returns to the initial position under the action of the elastic force of the second return spring 153, and the second micro switch button 131 and the second sliding member 154 return to the released position and the initial position respectively under the action of the return force of the second micro switch button 131, outputting a signal indicating the second power supply is switched on. In addition, since the first power supply transfers from switched on to switched off, the second lower driving rod 204 moves from the initial position to the driving position, and the second lower driving rod 204 contacts and drives the first pushing rod 141 aligned with the second lower driving rod 204 to perform a linear movement, so that the first sliding member 144 is pushed by the first pushing rod 141 to move downwardly to the actuating position through the cooperation of the slope surface of the first protrusion 1411 and the slope surface of the first sliding member 144, and the first actuating portion 1421 of the first sliding member 144 presses down the first micro switch button 121 to the triggered position, outputting a signal indicating the first power supply is switched off.
Referring back to Fig. 7 from Fig. 9, the second power supply transfers from switched on to switched off, the first upper driving rod 201 moves from the initial position to the driving position, and the first upper driving rod 201 contacts and drives the second pushing rod 151 aligned with the first upper driving rod 201 to perform a linear movement, so that the second sliding member 154 is pushed by the second pushing rod 151 to move downwardly to the actuating position through the cooperation of the slope surface of the second protrusion 1511 and the slope surface of the second sliding member 154, and the second actuating portion 1521 of the second sliding member 154 presses down the second micro switch button 131 to the triggered position, outputting a signal indicating the second power supply is switched off. In addition, since the first power supply is still off and the second lower driving rod 204 is still in the driving position, the first micro switch button 121 is still actuated and is in the triggered position, outputting a signal indicating the first power supply is switched off.
Because the first micro switch button 121 is in the triggered position when the first power supply is switched off, and the first micro switch button 121 is in the released position when the first power supply is switched on; the second micro switch button 131 is in the triggered position when the second power supply is switched off and the second micro switch button 131 is in the released position when the second power supply is switched on, the state indicating module 100 according to the second embodiment is switched-off-triggered.
The micro switch of the state indicating module 100 according to the present utility model is arranged in the state indicating module 100, which is convenient for installation and maintenance. And it is possible to provide one or more state indicating modules 100 in an expandable manner according to customer needs, thereby outputting one or more states indicating module signal. The state indicating module is small in size, easy to be installed and wired, and can be switched-on-triggered or switched-off-triggered according to the characteristics of the mechanism.
The exemplary implementation of the state indicating module 100 proposed by the present utility model is described in detail above with reference to the preferred embodiments. However, those skilled in the art can understand that variations and modifications can be made to the specific embodiments above without departing from the concept of the present utility model and various technical features and structures proposed by the utility model can be combined without going beyond the scope of the utility model.
