Description

Operation structure and dual power supply change-over switch

Technical Field

The present disclosure relates to the electrical field, and in particular, to a dual power transfer switch having an operating structure and including the same.

Background

In some mechanical devices, moving parts are often included, which can typically move between two positions. Depending on the application, it may be necessary to lock the moving part in an intermediate position between the two moving positions. In the electrical field, a dual power Transfer Switch (TSE) is a relatively important electrical device switch for powering important loads to ensure electrical continuity. TSEs generally include moving contacts, categorized by the number of operating positions in which the moving contacts are located, and may be categorized as:

Two-station TSE: a normal position (power on 1), a standby position (power on 2). Three-station TSE: a normal position (power on 1), an off position 0 (bipartite position), a standby position (power on 2), as shown in fig. 1.

In the prior art, for a three-station TSE, a complex mechanism is often required to realize switching between three positions, and particularly three or more active power components are required to trigger different switching actions, so that the operation logic is complex and cumbersome, and the cost is high. Therefore, there is a need for a simple and stable mechanism that allows the moving parts to be switched between different positions while reducing the number of active power components, simplifying the operating logic, and reducing costs.

Disclosure of utility model

An object of the present disclosure is to solve at least the drawbacks of the prior art, and to propose an operating structure comprising an operating structure for a moving part, the moving part being switchable between a first position, a second position and an intermediate position, the intermediate position being located between the first position and the second position, the operating structure comprising a first triggering part which can trigger a first setting movement of the moving part from the intermediate position to the first position; a second trigger portion that triggers a second setting movement of the moving member from the intermediate position to the second position; a third triggering portion that triggers a first reset movement of the moving member from the first position to the intermediate position and a second reset movement of the moving member from the second position to the intermediate position; the device is characterized by further comprising a first power component, wherein the first power component can enable a first execution end to conduct a first action, a second power component can enable a second execution end to conduct a second action, and a transmission assembly, wherein the transmission assembly is matched with the first power component and the second power component, so that at least one of the first triggering part, the second triggering part and the third triggering part can be triggered by the first action and the second action through the transmission assembly. Wherein the first action of the first power component is capable of triggering the first trigger portion through the transmission assembly to achieve a first setting motion only when the moving component is in an intermediate position; the second action of the second power component can trigger the second trigger part through the transmission assembly to realize second setting movement only when the moving component is located at the middle position; when the moving part is positioned at a first position, the second action of the second power part can trigger the third trigger part through the transmission assembly to realize first reset movement; when the moving part is located at the second position, the first action of the first power part can trigger the third trigger part through the transmission assembly to realize second reset movement.

Detailed Description

In order to make the objects, aspects and advantages of the technical solutions of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present disclosure. Unless otherwise indicated, terms used herein have the meaning common in the art. Like reference numerals in the drawings denote like parts.

In the description of the present disclosure, it should be noted that, unless explicitly specified and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the terms in this disclosure will be understood by those of ordinary skill in the art in the specific context.

Fig. 2 shows a schematic perspective view of a portion of a dual power transfer switch according to an embodiment of the present disclosure, it being seen that the operating structure according to the present disclosure comprises only two power components, namely a first power component 21 and a second power component 22, enabling flexible switching of the moving component 10 between three positions by means of a smart mechanical construction, as described in detail below.

Fig. 3a is an enlarged schematic perspective view of the moving part 10 of the part shown in fig. 2 and a triggering system comprising a first triggering part 11, a second triggering part 12 and a third triggering part 13, fig. 3b is a side view of the moving part 10 and the triggering system shown in fig. 3 a. As shown in fig. 3a and 3b, the first trigger portion 11 is disposed opposite the second trigger portion 12, both of which may be of identical external configuration, i.e. may be formed as a generally Z-shaped member comprising a plurality of lever arms. The two are also movable relative to each other to form an openable and closable locking aperture therebetween, which is open and can be used to receive the moving part 10. It should be appreciated that the relative movement of the first trigger portion 11 and the second trigger portion 12 may take a variety of forms, such as translational relative movement, rotational relative movement, and a combination of translational and rotational movement, provided that an openable and closable locking aperture can be formed therebetween, in accordance with the principles of the present disclosure. A linkage mechanism may be provided between the first trigger portion 11 and the second trigger portion 12 to allow simultaneous opposite movement of the two, i.e. either towards each other or away from each other. For example, the first trigger part 11 and the second trigger part 12 are connected together by a three-bar linkage (not shown), so that when the second trigger part 12 is pushed to move upwards, the second trigger part 12 transmits the movement to the first trigger part 11 by the three-bar linkage, the first trigger part 11 is driven to move downwards, and the locking port is opened; similarly, when the second trigger 12 is pushed to move downward, the second trigger 12 transmits the movement to the first trigger 11 through the three links, driving the first trigger 11 to move upward, and the locking port is closed.

The moving part 10 includes a gear portion, a pivot connection portion, a crank arm portion, etc., but its specific configuration is irrelevant to the main content of the present disclosure, and the gear portion, the pivot connection portion, the crank arm portion, etc. are regarded as one whole that can pivotally move together, i.e., the moving part 10, in the present disclosure. The moving member 10 is switchable relative to the first triggering part 11 and the second triggering part 12 between a first position, a second position and an intermediate position, the intermediate position being located between the first position and the second position. The first position corresponds to being on with a first power source (not shown), the second position corresponds to being on with a second power source (not shown), and the intermediate position corresponds to the double position. The first position is shown as being closer to the position of deflection of the first trigger part 11 (as shown in fig. 10 c), the second position is shown as being closer to the position of deflection of the second trigger part 12 (as shown in fig. 3 b), and the intermediate position is shown as the position of the moving member in the locking opening intermediate the first trigger part 11 and the second trigger part 12, i.e. being sandwiched by the first trigger part 11 and the second trigger part 12 (as shown in fig. 4 a).

The first triggering part 11 may trigger a first setting movement of the moving part 10 from the intermediate position to the first position, and the second triggering part 12 may trigger a second setting movement of the moving part 10 from the intermediate position to the second position. Specifically, as shown in fig. 4a, the moving member 10 is sandwiched by the first trigger 11 and the second trigger 12, and holds the closing spring 14 at the dead point position. When the second triggering part 12 is triggered (i.e., the second triggering part 12 is pushed to rotate in the drawing), the second triggering part 12 rotates counterclockwise and is released from abutment with the moving member 10, and the first triggering part 11 moves toward the second triggering part 12. The moving member 10 is slightly rotated counterclockwise by the pushing of the first trigger 11 so that the closing spring 14 passes over the dead point and is free to release, so that the moving member 10 performs the second setting movement to the second position. It will be appreciated that triggering the first triggering part 11 to cause the movement member 10 to perform the first setting movement to the first position is similar thereto and will not be expanded in detail.

The third triggering portion 13 is capable of triggering a first reset motion of the moving member 10 returning from the first position to the intermediate position and a second reset motion of the moving member 10 returning from the second position to the intermediate position. The opening is performed by means of an opening spring 15, which opening spring 15 releases potential energy when the third triggering part 13 is triggered, driving the moving part 10 back to the neutral position through a series of mechanical structures (not shown) and causing the first triggering part 11 and the second triggering part 12 to clamp the moving part 10. In addition, the third triggering portion 13 further includes an elastic member that gradually returns the third triggering portion 13 to the original state when the triggering of the third triggering portion 13 is completed.

It can be seen that switching the moving member 10 to the first position, the second position and the intermediate position requires triggering three different triggering parts, which typically requires three power members to provide three different triggering actions, but according to the operation structure of the present disclosure, the same function can be achieved by the first power member 21 and the second power member 22.

Fig. 5a shows a schematic view of the first power member 21 mated with the first transmission member 31, and fig. 5b shows an enlarged view of the first actuation end 211 of the first power member 21 in fig. 5a, according to an embodiment of the present disclosure. The first power member 21 and the second power member 22 may be completely identical in construction, and thus only the first power member 21 will be described as an example. The first power component 21 may include a first execution end 211 and may be configured to cause the first execution end 211 to perform a first action and a first return action that is opposite the first action. The first motion and the first return motion may be linear translation, rotational motion, a combination of rotational motion and linear translation, etc., and the power component performing the first motion and the first return motion may be a pneumatic cylinder, a hydraulic cylinder, a motor, a solenoid, etc., or a combination thereof.

As shown in fig. 5a, the first power member 21 may be a solenoid structure including a coil cavity and a first actuating end 211, and an elastic member, such as a biasing spring, is installed inside the coil cavity such that the first actuating end 211 is biased away from the coil cavity when the first power member 21 is not energized. When the first power member 21 is energized, an electromagnetic force is generated inside thereof against the spring biasing force such that the first execution end 211 of the first power member 21 performs a first action, i.e. the first execution end 211 performs a linear translation towards the coil cavity of the first power member 21. When the first power member 21 is de-energized, the elastic member in the first power member 21 causes the first power member 21 to perform a first return motion to return to an initial position, i.e., a state away from the coil cavity.

Notably, the operating structure according to the present disclosure may energize only one of the first power member 21 and the second power member 22 at a time to achieve the logical operation as described below.

As shown in fig. 5b, the first actuating end 211 includes a hook portion 2111, a pivot connection hole 2112, and a stop hole 2113. The hook portion 2111 is provided at the first execution end 211 furthest from the free end of the coil cavity, so that when the first power member 21 performs a first action, the hook portion 2111 can engage with a third transmission member (to be described later) to thereby move the third transmission member.

Returning to fig. 5a, the first transmission member 31 has a "7" shape with a longer section being a free end, the first transmission member 31 is fitted to the first execution end 211 of the first power member 21 by a shorter section, for example, the first transmission member 31 is pivotably mounted to the pivot connection hole 2112, and the first transmission member 31 may also be provided with a stopper portion that cooperates with the stopper hole 2113. By the restriction of the limiting hole 2113, the pivotal movement of the first transmission member 31 is limited between a first pivotal position as shown in fig. 5a and a second pivotal position, which may be analogous to fig. 10d (in fig. 10d the second member 32 is pivoted to the second pivotal position). Those skilled in the art will appreciate that the stop holes 2113 may be replaced by other forms such as, but not limited to, a chute, a stop, etc. The pivotable arrangement is such that: when the first power member 21 is caused to perform the first action and the first triggering portion 11 is in contact with the first transmission member 31, the first transmission member 31 may trigger the first triggering portion 11 since the first transmission member 31 is located at the first pivot position abutting the limiting hole 2113; when the first power member 21 performs the first return motion and the first trigger 11 contacts the first transmission member 31, the first transmission member 31 may be pivoted toward the second pivot position, and the first transmission member 31 may pivot away from the first trigger 11.

The first transmission member 31 is further provided with a resilient member biasing the first transmission member 31 in the first pivot position. In this biased position, the first transmission member 31 is held in the first pivot position against the limit hole 2113 when the force applied to the first transmission member 31 is in the same direction as the pivot moment generated by the biasing force of the elastic member against the pivot center of the first transmission member 31. Therefore, when the first power member 21 performs the first action, the first driving member 31 triggers the first triggering portion 11, and the generated force to the first driving member 31 is parallel and opposite to the first action direction, and the direction of the pivoting moment generated by the force is the same as the direction of the pivoting moment generated by the biasing force, as shown in fig. 10 b. In this biased position, when the force applied to the first transmission member 31 is opposite to the pivoting moment generated by the biasing force of the resilient member on the pivot center of the first transmission member 31, e.g. the force is in the same direction as the first action, the first transmission member 31 will pivot against the resilient member towards the second pivot position, which can be analogous to fig. 10d (in fig. 10d the second member 32 is pivoted to the second pivot position) to achieve a pivoting avoidance of the first trigger 11. The construction of the second transmission member 32 and the manner of connection to the second actuating end 221 are exactly the same as described above and will not be repeated here.

Fig. 6 is an enlarged perspective view of the third transmission member 33 in fig. 2, wherein the third transmission member 33 is a rod member having bent sections at both ends, and has a main body section 331, and the length of the main body section 331 is the maximum length of the third transmission member 33. The third transmission member 33 may be a member having two ends completely symmetrical, for example, one end thereof has a first bending section 332 perpendicular to the main body section 331 of the third transmission member 33 and extending from the main body section 331, and a second bending section 333 perpendicular to the first bending section 332 and located at the other end of the first bending section 332, the second bending section 333 being parallel to and opposite to the main body section 331, such that a portion of the main body section 331, the first bending section 332, and the second bending section 333 form an "n" shape.

The main body section 331 of the third transmission member 33 is pivotally mounted on the mounting portion such that the second bending section 333 is capable of rotational movement with the length of the first bending section 332 as a radius and a portion of the main body section 331 as a rotational axis for triggering the third triggering portion 13. Furthermore, the third transmission member 33 is also translatable both in a first direction parallel to the rotational axis of the third transmission member 33, i.e. in fig. 2 and 6 it is shown that the third transmission member 33 is translatable both upwards and downwards. Still further, the third transmission member 33 further includes a first limiting lug 334 and a second limiting lug 335, and the first limiting lug 334 and the second limiting lug 335 may abut against the mounting portion to limit the movement range of the third transmission member 33 in the first direction.

Fig. 7 illustrates a schematic perspective view of a moving part mated with an indicator according to an embodiment of the present disclosure. The operating structure further comprises an indicator 4, the indicator 4 being connectable with the moving part 10 to form a swinging guide mechanism, such that movement of the moving part 10 can bring the indicator 4 into swinging motion, and the swinging motion is only within a fixed angular range. Specifically, as shown in fig. 7, a fixed protrusion 101 is provided on the moving member 10, a slide groove 41 is provided at one end of the indicator 4, and the protrusion 101 is slidably provided in the slide groove 41, so that when the moving member 10 is rotated to a different position, the protrusion 101 drives the indicator 4 to pivot and the protrusion 101 moves correspondingly in the slide groove 41. As shown in fig. 8a-8c, the moving part 10 (partially shown) of fig. 7 is in a mated state with the indicator 4 in a different position, wherein fig. 8a shows the moving part 10 in a first position and, correspondingly, the chute 41 of the indicator 4 in a lowermost swing position; fig. 8b shows the moving part 10 in the neutral position and, correspondingly, the runner 41 of the indicator 4 in the neutral swing position; fig. 8c shows the moving part 10 in the second position and, correspondingly, the chute 41 of the indicator 4 in the uppermost swing position.

The indicator 4 may also comprise a plurality of indication marks, for example three, fixed to the end of the indicator opposite to the chute 41. In addition, the operation structure may further include an indication window, and when the indication member 4 is at different swing positions with the moving member 10 being at different positions, a corresponding one of the plurality of indication marks faces the indication window to indicate the position where the moving member 10 is in the current state.

Furthermore, according to one embodiment of the present disclosure, as shown in fig. 9, the indicator 4 is connected to the third transmission member 33, specifically, the first and second limit lugs 334 and 335 connected to the third transmission member 33, respectively, through two spring connections, such that when the indicator 4 swings up and down with the movement of the movement member 10, the third transmission member 33 is brought into translational movement in the above-mentioned first direction by the two springs.

Specifically, when the moving member 10 is located at the first position, the indicator 4 drives the third transmission member 33 to a position capable of being engaged with the second execution end 221, specifically, the first bending section 332 of the third transmission member 33 is engaged with the hook portion 2111 of the second execution end 221, as shown in fig. 10d, the hook portion 2111 can drive the third transmission member 33 to pivot, and further, the second bending section 333 of the third transmission member 33 can trigger the third trigger portion 13; when the moving member 10 is located at the second position, the driving indicator 4 drives the third transmission member 33 to a position where it can engage with the first execution end 211, not shown, but conceivable with reference to the above-described case where the moving member 10 is located at the first position; when the movement part 10 is in the intermediate position, the entrainer 4 entrains the third transmission part 33 to the intermediate position, as shown in fig. 10a, so that neither the first execution end 211 nor the first execution end 221 can engage with the third transmission part 33. This arrangement facilitates the operation logic process as described later, so that the third trigger portion 13 can be triggered by the third transmission member 33 only when the moving member 10 is located at the first position or the second position, preventing the moving member 10 from being triggered to reset when it is located at the intermediate position, that is, the switching-off mechanism performs the "space-division" operation corresponding to the moving contact being located at the double-division position, causing mechanical damage, and preventing the simultaneous triggering of one of the first trigger portion 11 or the second trigger portion 12 and the third trigger portion 13, so that the reset motion is performed immediately after the setting motion, that is, the switching-off immediately after the switching-on.

The operation of the moving part 10 for the first setting movement to the first position and for the first resetting movement back to the intermediate position is described in detail below in connection with fig. 10a-10 d. The second setting movement and the second resetting movement are similar thereto, as will be understood and imagined from the following description.

Fig. 10a shows the moving part 10 in the neutral position and the third transmission part 33 in the neutral position, which corresponds to the double position. In this state, the first triggering part 11 and the second triggering part 12 are in the open position, and are separated from each other, so that the first transmission part 31 and the second transmission part 32 can be driven by the corresponding first power part 21 and second power part to trigger the corresponding first triggering part 11 and second triggering part 12. However, due to the length of the third transmission member 33, both the first and second execution ends 211 and 221 are driven by the corresponding first and second power members 21 and 22, but cannot be engaged with the third transmission member 33, which is shown in fig. 10a as having a gap between both ends of the third transmission member 33 and the ends of the first and second transmission members 31 and 32, respectively, as shown by the dotted lines in fig. 10 a. The indicator 4 can then indicate via an indicator window (not shown) that the moving part 10 is in the neutral position, i.e. corresponds to the bisecting position.

Fig. 10b shows that the first power member 21 is energized to perform the first action, driving the first transmission member 31 to trigger the first trigger portion 11, so that the moving member 10 performs the first setting movement from the intermediate position to the first position, and the moving member 10 swings the indicator 4, and the indicator 4 swings the third transmission member 33 upward, so that the second execution end 221 can be engaged with the third transmission member 33, and the first execution end 211 cannot be engaged with the third transmission member 33.

Fig. 10c shows that both the first triggering part 11 and the second triggering part 12 are close to each other in a fully closed position such that the first transmission member 31 and the second transmission member 32 cannot trigger the corresponding first triggering part 11 and second triggering part 12, and in fig. 10c, it is shown that the ends of the first transmission member 31 and the second transmission member 32 have a gap with the ends of the first triggering part 11 and the second triggering part 12, respectively, which gap is shown as a dotted line in fig. 10 c. In this state, the moving member 10 is completely at the first position, and the first power member 21 is deenergized to perform the first return operation and return to the initial position.

Fig. 10d shows that the second power component 22 is electrified to perform the second action, the second execution end 221 drives the third transmission component 33 to pivot, so as to trigger the third trigger portion 13, so as to trigger the moving component 10 to perform the first reset motion, and the first trigger portion 11 and the second trigger portion 12 perform corresponding motions so as to realize the re-clamping of the moving component between the two. Movement of the second trigger 12 causes the pivoting of the second transmission member 32 to be avoided so that no mechanical impact damage occurs.

Next, when the second power member 22 is powered down to perform the second return motion and returns to the initial position, since the third trigger portion 13 has an elastic member (not shown), the elastic member gradually returns the third trigger portion 13 and the third transmission member 33 to the original state during the second return motion performed by the second execution end 221. The complete return of the moving part 10 to the intermediate position brings the indicator 4 back to the original position and thus the third transmission part 33 back to the intermediate position, i.e. the operating structure and the moving part 10 return to the state shown in fig. 10 a.

As can be seen from the above process, when the moving member 10 is in the intermediate position, the first power member 21 is energized to set the moving member 10 to the first position, and the second power member 22 is energized to reset the moving member 10 to the intermediate position; similarly, when the moving member 10 is in the neutral position, energizing the second power member 22 sets the moving member 10 to the second position, and energizing the first power member 21 resets the moving member 10 to the neutral position. Only one of the first power member 21 and the second power member 22 is energized at a time. According to the operation structure disclosed by the invention, the triggering parts of the three triggering parts are controlled by two coils through ingenious mechanical structure, the manufacturing production cost is reduced, and the operation control is simple. In addition, "air separation" can be prevented, mechanical damage is avoided, and simultaneous triggering of one of the first triggering part 11 or the second triggering part 12 and the third triggering part 13 is prevented, so that a reset motion is performed immediately after a setting motion is caused, that is, a situation corresponding to an immediate opening after a closing motion is caused.

The present disclosure proposes another implementation, by means of the interlocking mechanism 5, a function similar to that of the movable third transmission member 33 described above, namely, preventing "air separation" and preventing the situation of opening immediately after closing.

Fig. 11 shows a schematic perspective view of an operating structure and a moving part according to another embodiment of the present disclosure, wherein the operating structure may not comprise an indicator 4 and the third transmission part 33 is only pivotally movable and not translatable in a first direction, which is parallel to the pivot axis of the third transmission part 33. The length of the third transmission member 33 is set such that both the first and second execution ends 211, 221 can be engaged with the third transmission member 33.

Specifically, fig. 12 is an enlarged schematic perspective view of the third transmission member 33 in fig. 11, wherein the third transmission member 33 has a main body section 331, and the length of the main body section 331, that is, the maximum length of the third transmission member 33, and further, both ends of the third transmission member 33 include first bending sections 332 extending from the main body section 331 and perpendicular to the main body section 331, the first bending sections 332 for engagement with the first and second actuating ends 211 and 221, respectively. However, the third transmission member 33 has a second bending section 333 at only one end, the second bending section 333 is perpendicular to the first bending section 332 and is located at the other end of the first bending section 332, and the second bending section 333 is parallel to and opposite to the main body section 331, such that at the end, a portion of the main body section 331, the first bending section 332 and the second bending section 333 form an "n" shape; at the other end, a portion of the body section 331 and the first bend 332 form a "7" shape. This design reduces the footprint of the third transmission member 33, reducing its potential for interference with other components.

Fig. 13 is a schematic view of a portion of an interlock mechanism 5 according to an embodiment of the present disclosure, as shown in fig. 13, the interlock mechanism 5 may be mated with a third trigger portion 13. Furthermore, the interlock mechanism 5 is configured to: when the moving member 10 is located at the intermediate position, in the case where the third trigger portion 13 is continuously triggered, the first trigger portion 11 or the second trigger portion 12 is triggered, and the corresponding first setting movement or second setting movement is normally performed; in the case where the third triggering portion 13 is continuously triggered, when the moving member 10 is set to the first position or the second position, the corresponding first reset motion or the second reset motion is not triggered, and when the triggering of the third triggering portion 13 is disconnected and the third triggering portion 13 is triggered again, the corresponding first reset motion or the second reset motion is triggered.

According to an embodiment of the present disclosure, the interlocking mechanism may include a first interlocking member 51 and a second interlocking member 52. When the third triggering part 13 is triggered, the first interlocking part 51 is triggered, and then the second interlocking part 52 is triggered by the first interlocking part 51, and the second interlocking part 52 triggers a subsequent series of mechanisms (not shown) so that the moving part 10 performs the first resetting movement or the second resetting movement.

Specifically, fig. 13 shows four states in which the interlock mechanism 5 is engaged with the third trigger portion 13. The state i is a state when the moving member is in the first position or the second position, in which the third trigger 13 can be triggered, i.e., the first reset motion or the second reset motion is performed. During the first or second resetting movement, the first interlocking part 51 may move from the state i to the state ii, i.e. to the right with respect to the positioning part 53, due to other parts (not shown) of the interlocking mechanism 5. In this case, when the third triggering part 13 is triggered (rotated down) again (corresponding to the state iii), the third triggering part 13 cannot trigger the first interlocking part 51, and therefore cannot trigger the second interlocking part 52, and further cannot trigger a subsequent series of mechanisms (not shown) through the second interlocking part 52, that is, the operation structure cannot perform the reset operation when the moving part 10 is in the intermediate position under the action of the interlocking mechanism 5, which can avoid the "space division" damage mechanism.

Further, when the third triggering part 13 is continuously triggered (i.e., corresponding to the state iii), the first triggering part 11 or the second triggering part 12 can be triggered, and at this time, the interlocking is released, the first interlocking part 51 is reset leftward with respect to the positioning part 53 so as to be engaged with the third triggering part 13 (i.e., corresponding to the state iv), and since it is blocked by the third triggering part 13, the first interlocking part 51 is not contacted with the second interlocking part 52, that is, an erroneous operation of automatically triggering the first reset motion or the second reset motion does not occur. In this case, the triggering of the third triggering part 13 must be released in order to restore the interlocking mechanism 5 to the state i and thus trigger the first or second resetting movement.

The operation of the moving part 10 for a first setting movement to the first position and for a first resetting movement back to the intermediate position is described in detail below in connection with fig. 14a-14 d. The second setting movement and the second resetting movement are similar thereto, as will be understood and imagined from the following description.

Fig. 14a shows the moving part 10 in the neutral position and the third transmission part 33 in the neutral position, which corresponds to the double position. In this state, the first and second transmission members 31 and 32 may be driven by the corresponding first and second power members 21 and 22 to trigger the corresponding first and second triggering portions 11 and 12, and the first and second execution ends 211 and 221 may be driven by the corresponding first and second power members 21 and 22 to be engaged with the third transmission member 33.

Fig. 14b shows that the first power component 21 is electrified to perform the first action, the first execution end 211 drives the third transmission component 33 to pivot so as to continuously trigger the third triggering portion 13, and drives the first transmission component 31 to trigger the first triggering portion 11, and it is noted that the continuous triggering of the third triggering portion 13 is before the triggering of the first triggering portion, and the moving component 10 can normally perform the first setting movement from the intermediate position to the first position due to the interlocking mechanism as described above.

Fig. 14c shows that both the first triggering part 11 and the second triggering part 12 are close to each other in a fully closed position such that the first transmission member 31 and the second transmission member 32 cannot trigger the corresponding first triggering part 11 and second triggering part 12, and in fig. 14c, it is shown that the ends of the first transmission member 31 and the second transmission member 32 have a gap with the ends of the first triggering part 11 and the second triggering part 12, respectively, which gap is shown as a dotted line in fig. 14 c. In this state, the moving member 10 is completely at the first position, and the first power member 21 is deenergized to perform the first return operation and return to the initial position. The continued triggering of the third triggering part 13 is interrupted, whereby the moving part 10 is able to perform a first reset movement or a second reset movement when the third triggering part 13 is subsequently triggered again, due to the interlocking mechanism as described above.

Fig. 14d shows that the second power component 22 is electrified to perform the second action, the second execution end 221 drives the third transmission component 33 to pivot, so as to trigger the third trigger portion 13, so that the moving component 10 can be triggered to perform the first reset motion, and the first trigger portion 11 and the second trigger portion 12 perform corresponding motions so as to realize the re-clamping of the moving component 10 between the two. Movement of the second trigger 12 causes the pivoting of the second transmission member 32 to be avoided so that no mechanical impact damage occurs.

Next, when the second power member 22 is powered down to perform the second return motion and returns to the initial position, since the third trigger portion 13 has an elastic member (not shown), the elastic member gradually returns the third trigger portion 13 and the third transmission member 33 to the original state during the second return motion performed by the second execution end 221, and the operating structure and the moving member 10 return to the state shown in fig. 14 a.

According to the operation structure of this embodiment, the structure is more compact, the third transmission member 33 is not required to perform translational movement and the cooperation with the indicator 4 is omitted, the interlocking mechanism is skillfully utilized to realize the "space division" prevention function, mechanical damage is avoided, and the simultaneous triggering of one of the first triggering part 11 or the second triggering part 12 and the third triggering part 13 is prevented, so that the situation that the reset movement is performed immediately after the setting movement is caused, namely, the situation corresponds to the situation that the brake is opened immediately after the brake is closed.

According to the present disclosure, there is also provided a double power transfer switch including the above-described operation structure, wherein the moving part 10 corresponds to a moving contact assembly, a first position corresponds to a position to be turned on with a first power source, a second position corresponds to a position to be turned on with a second power source, an intermediate position corresponds to a double-divided position, a first setting movement and a second setting movement correspond to a first closing movement and a second closing movement, respectively, and a first reset movement and a second reset movement correspond to a first opening movement and a second opening movement, respectively.

According to the dual-power transfer switch disclosed by the invention, the switching operation of the dual-power transfer switch can be controlled only by controlling the power-on sequence of the first power component and the second power component, so that the dual-power transfer switch is convenient to operate, simple in logic and easy to operate.
