Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0049] In the description of the present application, unless otherwise specifically stated and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements.

[0052] Dual power transfer switch is a device capable of automatic or manual switching between normal power (also known as main power) and standby power. When the normal power is abnormal (such as power failure, voltage or frequency exceeding the set range, etc.), the transfer switch disconnects the normal power and switches to the standby power to supply power to the load. When the normal power returns to normal, the transfer switch disconnects the standby power and switches back to the normal power to supply power to the load. The above switching operation is completed by the operating mechanism inside the dual power transfer switch.

[0053] The existing operating mechanism has many parts and a complex structure (for example, a combination of various complex sheet metal formed parts or a combination of various complex injection molded parts), resulting in high manufacturing cost of the operating mechanism. Therefore, it is an urgent problem in the field to provide a simple structure operating mechanism for reliable switching of dual power.

[0054] In order to solve or improve the above technical problems, as shown in Figure 2 and Figure 3 , the first aspect, the embodiments of the present application provide an operating mechanism 100, which relates to the field of low-voltage electrical apparatus and is mainly applied to a dual power transfer switch for switching of dual power.

[0055] As shown in Figure 4 , Figure 14 and Figure 12 , the operating mechanism 100 provided by the embodiments includes a first mounting member 111, a dialing assembly 120, a second mounting member 112, a transmission assembly and an elastic assembly.

[0056] The first mounting member 111 is provided with a first straight hole 1111 and a second straight hole 1112, and is provided with a first arc hole 1113 and a second arc hole 1114. The dialing assembly 120 comprises a dial 121, a first dialing claw 122 and a second dialing claw 123. The dial 121 is rotatably arranged relative to the first mounting member 111. The first dialing claw 122 is provided with a first sliding part 1221 penetrating the first straight hole 1111. The second dialing claw 123 is provided with a second sliding part 1231 penetrating the second straight hole 1112. The dial 121 is used to rotate in a first direction x or a second direction y, so as to drive the first dialing claw 122 and the second dialing claw 123 to move. The first direction x and the second direction y are opposite. The second mounting member 112 is connected with the first mounting member 111, and is provided with a third arc hole 1121 and a fourth arc hole 1122. The transmission assembly comprises a first driving member 131, a second driving member 132, a first driven member 133 and a second driven member 134. The first driving member 131 penetrates the first arc hole 1113 and is movably connected with the first dialing claw 122. The second driving member 132 penetrates the second arc hole 1114 and is movably connected with the second dialing claw 123. The first driven member 133 penetrates the third arc hole 1121. The second driven member 134 penetrates the fourth arc hole 1122. The elastic assembly comprises a first elastic member 1411 and a second elastic member 1412. The first elastic member 1411 is connected with the first driving member 131 and the first driven member 133 respectively. The second elastic member 1412 is connected with the second driving member 132 and the second driven member 134 respectively.

[0057] It should be noted that "the dial 121 is rotatably arranged relative to the first mounting member 111" can be understood as that the dial 121 can rotate relative to the first mounting member 111. Specifically, the dial 121 can rotate in the first direction x or the second direction y. The dial 121 can be driven to rotate relative to the first mounting member 111 in an electric manner or a manual manner. The "straight hole" can be understood as that the extension track of the hole is a straight line. The "arc hole" can be understood as that the extension direction of the hole is an arc line.

[0058] Exemplarily, the first elastic member 1411 and / or the second elastic member 1412 can be a torsion spring, a cylindrical spring, a spring sheet, an elastic arm or the like, which is not limited specifically herein.

[0059] It can be understood that the operating mechanism 100 provided by the embodiment reduces the number of complex components by opening the straight hole and the arc hole, and links and cooperates with the dial 121, the dialing claw, the driving member and the driven member, so as to realize the conversion of the dual power supply in a simpler structure, thereby having a lower manufacturing cost. Specifically, the conversion principle of the dual power supply is as follows:

[0060] As Figure 16 , Figure 17 and Figure 8As shown, when the normal power supply is abnormal, the dial 121 is rotated in the second direction y to drive the first pawl 122 to move in the direction close to the second pawl 123 under the guidance of the first straight hole 1111, thereby driving the first driving part 131 to move in the direction close to the second driving part 132 under the guidance of the first arc hole 1113, and further driving the first driven part 133 to move in the direction close to the second driven part 134 under the guidance of the third arc hole 1121 through the first elastic part 1411, so as to realize that the first driven part 133 drives the movable contact on the side of the normal power supply to open, and as the dial 121 is further rotated in the second direction y, the second pawl 123 is driven to move in the direction away from the first pawl 122 under the guidance of the second straight hole 1112, thereby driving the second driving part 132 to move in the direction away from the first driving part 131 under the guidance of the second arc hole 1114, and further driving the second driven part 134 to move in the direction away from the first driven part 133 under the guidance of the fourth arc hole 1122 through the second elastic part 1412, so as to realize that the second driven part 134 drives the movable contact on the side of the standby power supply to close, thereby switching to the standby power supply to supply power to the load.

[0061] As shown in Figure 14 , Figure 15 and Figure 10 , when the normal power supply returns to normal, the dial 121 is rotated in the first direction x to drive the second pawl 123 to move in the direction close to the first pawl 122 under the guidance of the second straight hole 1112, thereby driving the second driving part 132 to move in the direction close to the first driving part 131 under the guidance of the second arc hole 1114, and further driving the second driven part 134 to move in the direction close to the first driven part 133 under the guidance of the fourth arc hole 1122 through the second elastic part 1412, so as to realize that the second driven part 134 drives the movable contact on the side of the standby power supply to open, and as the dial 121 is further rotated in the first direction x, the first pawl 122 is driven to move in the direction away from the second pawl 123 under the guidance of the first straight hole 1111, thereby driving the first driving part 131 to move in the direction away from the second driving part 132 under the guidance of the third arc hole 1121, and further driving the first driven part 133 to move in the direction away from the second driven part 134 under the guidance of the third arc hole 1121 through the first elastic part 1411, so as to realize that the first driven part 133 drives the movable contact on the side of the normal power supply to close, thereby switching back to the normal power supply to supply power to the load.

[0062] It should be noted that the operating mechanism 100 has a double-split state between the standby closing state and the normal closing state, i.e., the normal power supply is open and the standby power supply is open, as shown in Figure 4 , at this time, neither the normal power supply nor the standby power supply supplies power to the load.

[0063] As shown in Figure 4 the third straight hole 1222 of the first pawl 122 is perpendicular to the extension direction of the first straight hole 1111, the extension direction of the fourth straight hole 1232 of the second pawl 123 is perpendicular to the extension direction of the second straight hole 1112, the second mounting member 112 is provided with a fifth arc hole 1123 and a sixth arc hole 1124 symmetrically distributed, the first driving member 131 is respectively threaded through the third straight hole 1222, the first arc hole 1113 and the fifth arc hole 1123, and the second driving member 132 is respectively threaded through the fourth straight hole 1232, the second arc hole 1114 and the sixth arc hole 1124.

[0064] It can be understood that the fifth arc hole 1123 can further provide a guiding effect for the first driving member 131, so that the first driving member 131 can move more stably along the set trajectory, the sixth arc hole 1124 can further provide a guiding effect for the second driving member 132, so that the second driving member 132 can move more stably along the set trajectory, so as to realize reliable conversion of dual power supply. The third straight hole 1222 is used for threading the first driving member 131, so that the first driving member 131 is movably connected with the first pawl 122, and the fourth straight hole 1232 is used for threading the second driving member 132, so that the second driving member 132 is movably connected with the second pawl 123, so as to improve the situation that the driving member and the pawl are structurally interfered with each other due to different movement trajectories of the pawl and the driving member (the pawl moves linearly along the straight hole, and the driving member moves along the arc hole).

[0065] Of course, for the above-mentioned embodiment, the driving member can also be provided with a sliding block, and the pawl can be provided with a guide rail slidingly matched with the sliding block, so that the sliding direction of the sliding block relative to the guide rail is perpendicular to the extension direction of the straight hole, and the situation that the driving member and the pawl are structurally interfered with each other can also be improved, and the mode of movably connecting the driving member and the pawl is not limited here.

[0066] As shown in Figure 5 and Figure 5 to Figure 7 in an embodiment, the first sliding part 1221 includes a plurality of first sliding shafts 12211 arranged at intervals, each first sliding shaft 12211 is threaded through the first straight hole 1111, and the second sliding part 1231 includes a plurality of second sliding shafts 12311 arranged at intervals, each second sliding shaft 12311 is threaded through the second straight hole 1112, so as to limit the rotation of the first pawl 122 and the second pawl 123 relative to the first mounting member 111, so that the pawl moves linearly relative to the first mounting member 111 along the extension direction of the straight hole.

[0067] In another embodiment, the first sliding part 1221 is a first strip-shaped sliding block penetrating the first straight hole 1111, and the second sliding part 1231 is a second strip-shaped sliding block penetrating the second straight hole 1112, which can also limit the rotation of the first pawl 122 and the second pawl 123 relative to the first mounting member 111, so that the pawls only move linearly relative to the first mounting member 111 along the extension direction of the straight hole.

[0068] As shown in the drawings, Figure 2 In one embodiment, the dial 121 comprises a rotating part 1211 and a pushing part 1212 connected together, the first pawl 122 is provided with two first force receiving parts 1224 spaced apart from each other and a first groove 1223 between the two first force receiving parts 1224, and the second pawl 123 is provided with two second force receiving parts 1234 spaced apart from each other and a second groove 1233 between the two second force receiving parts 1234.

[0069] It can be understood that, taking the side of the commonly used power supply as an example, when the rotating part 1211 rotates in the first direction x, the pushing part 1212 abuts against the first force receiving part 1224 on the side of the first pawl 122 away from the second pawl 123 along the first groove 1223, thereby driving the first pawl 122 to move in the direction away from the second pawl 123 under the guidance of the first straight hole 1111, and finally causing the first driven member 133 to drive the movable contact of the side of the commonly used power supply to close; in the case that the commonly used power supply is closed, when the rotating part 1211 rotates in the second direction y, the pushing part 1212 abuts against the first force receiving part 1224 on the side of the first pawl 122 close to the second pawl 123 along the first groove 1223, thereby driving the first pawl 122 to move in the direction close to the second pawl 123 under the guidance of the first straight hole 1111, and finally causing the first driven member 133 to drive the movable contact of the side of the commonly used power supply to open. The closing and opening of the side of the standby power supply are the same as the above, and thus will not be described here.

[0070] As shown in the drawings, Figure 5 and Figure 14 In one embodiment, the operating mechanism 100 further comprises a linkage assembly 150, the linkage assembly 150 comprising a first linkage 151, a second linkage 152, a third linkage 153, and a fourth linkage 154, one end of the first linkage 151 being rotationally connected with the first driving member 131, the other end of the first linkage 151 being rotationally connected with one end of the second linkage 152, the other end of the second linkage 152 being rotationally connected with the first driven member 133, one end of the third linkage 153 being rotationally connected with the second driving member 132, the other end of the third linkage 153 being rotationally connected with one end of the fourth linkage 154, and the other end of the fourth linkage 154 being rotationally connected with the second driven member 134.

[0071] Understandably, the linkage assembly 150 limits the movement trajectories of the driving and driven components, enabling the operating mechanism 100 to reliably switch between dual power supplies. The specific principle is as follows:

[0072] For the side with the commonly used power supply, such as Figure 15 As shown, when the first active member 131 is driven by the first pawl 122 to move to a certain position in a direction away from the second active member 132, the first elastic member 1411 stretches and stores energy; this state is the pre-closing of the normal power supply. Figure 16 As shown, as the first active member 131 continues to move until the first elastic member 1411 is stretched to a certain extent, the first driven member 133 is instantly driven from the end of the third arc-shaped hole 1121 near the fourth arc-shaped hole 1122 by the first elastic member 1411 to the end of the third arc-shaped hole 1121 away from the fourth arc-shaped hole 1122, thus completing the closing of the normal power supply.

[0073] For the backup power supply side, such as Figure 17 As shown, when the second active member 132 is driven by the second pawl 123 to move to a certain position in a direction away from the first active member 131, the second elastic member 1412 stretches and stores energy; this state is the pre-closing of the backup power supply. Figure 2 As shown, as the second active member 132 continues to move until the second elastic member 1412 is stretched to a certain extent, the second driven member 134 is instantly driven from the end of the fourth arc-shaped hole 1122 that is close to the third arc-shaped hole 1121 to the end of the fourth arc-shaped hole 1122 that is far away from the third arc-shaped hole 1121 by the second elastic member 1412, thus completing the closing of the backup power supply.

[0074] like Figure 3 , Figure 11 and Figure 2As shown, further, the operating mechanism 100 further comprises a third mounting member 142 and a fourth mounting member 143, the second mounting member 112 is arranged between the first mounting member 111 and the third mounting member 142 at intervals, the third mounting member 142 is arranged between the second mounting member 112 and the fourth mounting member 143 at intervals, the dial assembly 120 is located on the side of the first mounting member 111 away from the second mounting member 112, the connecting rod assembly 150 is located between the second mounting member 112 and the third mounting member 142, each of the first driving member 131, the second driving member 132, the first driven member 133 and the second driven member 134 is movably connected with the third mounting member 142 and the fourth mounting member 143 respectively, the first elastic member 1411 and the second elastic member 1412 are both provided with a plurality of elastic members, among the plurality of first elastic members 1411, a part of the first elastic members 1411 are located between the first mounting member 111 and the second mounting member 112, and the other part of the first elastic members 1411 are located between the third mounting member 142 and the fourth mounting member 143; among the plurality of second elastic members 1412, a part of the second elastic members 1412 are located between the first mounting member 111 and the second mounting member 112, and the other part of the second elastic members 1412 are located between the third mounting member 142 and the fourth mounting member 143.

[0075] Exemplarily, the way that the driving member and the driven member are movably connected with the mounting member can be that: arc-shaped holes are provided on the third mounting member 142 and the fourth mounting member 143 for penetrating the driving member and the driven member, of course, each of the first driving member 131, the second driving member 132, the first driven member 133 and the second driven member 134 can be connected with the first mounting member 111 and the second mounting member 112 through springs to realize the movable connection, which is not specifically limited here.

[0076] It can be understood that, by providing a plurality of first elastic members 1411 and a plurality of second elastic members 1412, the common action of the plurality of first elastic members 1411 can more stably drive the first driven member 133 to move, and the common action of the plurality of second elastic members 1412 can more stably drive the second driven member 134 to move, so that the operating mechanism 100 can more reliably perform the conversion of the dual power supply.

[0077] As shown in Figure 3 and Figure 1 to Figure 3 , still further, at least one of the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143 is in a plate structure, and the operating mechanism 100 further comprises at least two connecting members 144, each of the connecting members 144 is connected to the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143 respectively.

[0078] It can be understood that configuring at least one of the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143 as a plate-shaped structure can reduce the volume and the external size of the operating mechanism 100, facilitate the miniaturization and lightweight design of the operating mechanism 100, and reduce the manufacturing cost of the operating mechanism 100.

[0079] As shown in Figure 10 and Figure 3 In one embodiment, the operating mechanism 100 further includes a third mounting member 142, a fourth mounting member 143, a manual assembly 160 and an electric assembly 170. The second mounting member 112 is arranged between the first mounting member 111 and the third mounting member 142, and the third mounting member 142 is arranged between the second mounting member 112 and the fourth mounting member 143. The manual assembly 160 includes a rotating member 161 and a holding member 162 connected with each other, and the rotating member 161 is rotatably connected with the third mounting member 142 and the fourth mounting member 143. The electric assembly 170 includes a driving member 171 and a connecting shaft 172 connected with each other, and the driving member 171 is arranged on the first mounting member 111 and used to drive the connecting shaft 172 to rotate. The connecting shaft 172 is rotatably arranged on the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143, and the connecting shaft 172 is connected with the dial 121 and the rotating member 161 and used to drive the dial 121 and the rotating member 161 to synchronously rotate along the first direction x or the second direction y.

[0080] It should be noted that the connecting shaft 172 is rotatably arranged on the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143, which means that the connecting shaft 172 can rotate relative to the first mounting member 111, the second mounting member 112, the third mounting member 142 and the fourth mounting member 143. For example, a connecting hole can be arranged on the mounting member and gap-fitted with the connecting shaft 172, or a clearance can be arranged to avoid the connecting shaft 172.

[0081] For example, the driving member 171 can be a device capable of outputting torque, such as a motor or a motor, which is not limited here.

[0082] It can be understood that the synchronous rotation of the dial 121 and the rotating member 161 along the first direction x or the second direction y can be driven by the driving member 171, or can be driven by the holding member 162, so that the conversion process of the dual power supply can be automatically or manually completed.

[0083] As shown in Figure 18 to Figure 20 and Figure 9As shown, further, the operating mechanism 100 further comprises an on-off assembly and an indicating member 180, the on-off assembly is arranged on the first mounting member 111 or the second mounting member 112, and comprises a first micro switch 145 and a second micro switch 146, the first micro switch 145 and the second micro switch 146 are respectively electrically connected with the driving member 171. The indicating member 180 is slidingly connected with at least one of the first mounting member 111 and the second mounting member 112, the indicating member 180 is located between the first micro switch 145 and the second micro switch 146, the first driven member 133 is connected with the indicating member 180, and can drive the indicating member 180 to trigger the first micro switch 145 when the dial 121 rotates along the first direction x, the second driven member 134 is connected with the indicating member 180, and can drive the indicating member 180 to trigger the second micro switch 146 when the dial 121 rotates along the second direction y.

[0084] It can be understood that, based on the design of the above structure, the user can judge the working state of the operating mechanism 100 by observing the moving position of the indicating member 180, at the same time, the indicating member 180 can trigger the first micro switch 145 and the second micro switch 146 electrically connected with the driving member 171 when moving, thereby realizing the mechanical and electrical linkage, the specific process is as follows:

[0085] As shown in Figure 18 and Figure 13 , in the process of converting the operating mechanism 100 to the normally closed state, the driving member 171 drives the connecting shaft 172 to make the dial 121 and the rotating member 161 rotate synchronously along the first direction x, so that the first driven member 133 drives the indicating member 180 to move along the direction close to the first micro switch 145, until the first micro switch 145 is triggered, thereby disconnecting the power supply of the driving member 171 (i.e. disconnecting the power supply of the normally used power supply to the driving member 171), and the position of the indicating member 180 indicates that the operating mechanism 100 is in the normally closed state; as shown in Figure 20 and Figure 18 to Figure 20 , in the process of converting the operating mechanism 100 to the standby closed state, the driving member 171 drives the connecting shaft 172 to make the dial 121 and the rotating member 161 rotate synchronously along the second direction y, so that the second driven member 134 drives the indicating member 180 to move along the direction close to the second micro switch 146, until the second micro switch 146 is triggered, thereby disconnecting the power supply of the driving member 171 (i.e. disconnecting the power supply of the standby power supply to the driving member 171).

[0086] As shown in Figure 18Further, as shown, the indicating member 180 is provided with a third force receiving portion 181, a fourth force receiving portion 182, and a fifth force receiving portion 183, the fifth force receiving portion 183 being arranged between the third force receiving portion 181 and the fourth force receiving portion 182, the third force receiving portion 181 and the fifth force receiving portion 183 having a third groove 184 therebetween, and the fourth force receiving portion 182 and the fifth force receiving portion 183 having a fourth groove 185 therebetween; when the indicating member 180 moves in a direction to trigger the first micro switch 145, the first follower 133 can abut the third force receiving portion 181 from the fifth force receiving portion 183 along the third groove 184, and the second follower 134 can slide out of the fourth groove 185 and abut the fourth force receiving portion 182; when the indicating member 180 moves in a direction to trigger the second micro switch 146, the second follower 134 can abut the fourth force receiving portion 182 from the fifth force receiving portion 183 along the fourth groove 185, and the first follower 133 can slide out of the third groove 184 and abut the third force receiving portion 181.

[0087] It can be understood that, based on the design of the above structure, the indicating member 180 has a protection function in addition to indicating the working state of the operating mechanism 100 and cooperating with the first micro switch 145 and the second micro switch 146, which is as follows:

[0088] As shown in FIG. 6, in the process of the operating mechanism 100 converting to the normally closed state, the indicating member 180 moves in a direction to trigger the first micro switch 145, the first follower 133 abuts the third force receiving portion 181 from the fifth force receiving portion 183 along the third groove 184, and the second follower 134 can slide out of the fourth groove 185 and abut the fourth force receiving portion 182, so that the second follower 134 cannot convert from the standby open state to the closed state, achieving the protection function. Figure 20 As shown in FIG. 7, in the process of the operating mechanism 100 converting to the standby closed state, the indicating member 180 moves in a direction to trigger the second micro switch 146, the second follower 134 abuts the fourth force receiving portion 182 from the fifth force receiving portion 183 along the fourth groove 185, and the first follower 133 can slide out of the third groove 184 and abut the third force receiving portion 181, so that the first follower 133 cannot convert from the normally open state to the closed state, achieving the protection function. Figure 19 As shown in FIG. 7, in the process of the operating mechanism 100 converting to the standby closed state, the indicating member 180 moves in a direction to trigger the second micro switch 146, the second follower 134 abuts the fourth force receiving portion 182 from the fifth force receiving portion 183 along the fourth groove 185, and the first follower 133 can slide out of the third groove 184 and abut the third force receiving portion 181, so that the first follower 133 cannot convert from the normally open state to the closed state, achieving the protection function. Figure 3 As shown in FIG. 8, when the operating mechanism 100 is in the double open state, the first follower 133 and the second follower 134 abut the fifth force receiving portion 183 respectively, at this time the indicating member 180 does not trigger the first micro switch 145 or the second micro switch 146.

[0089] As shown in FIG. 6, in the process of the operating mechanism 100 converting to the normally closed state, the indicating member 180 moves in a direction to trigger the first micro switch 145, the first follower 133 abuts the third force receiving portion 181 from the fifth force receiving portion 183 along the third groove 184, and the second follower 134 can slide out of the fourth groove 185 and abut the fourth force receiving portion 182, so that the second follower 134 cannot convert from the standby open state to the closed state, achieving the protection function. ​As shown, further, the second mounting member 112 is provided with a fifth straight hole 1125, and the indicating member 180 is provided with a third sliding portion 186 penetrating through the fifth straight hole 1125, so as to realize the sliding connection between the indicating member 180 and the second mounting member 112, so that the indicating member 180 can move in the direction of triggering the first micro switch 145 or in the direction of triggering the second micro switch 146. Of course, a sliding block can also be arranged on the indicating member 180, and a guide rail in sliding cooperation with the sliding block is arranged on the second mounting member 112, and the sliding connection between the indicating member 180 and the second mounting member 112 can also be realized, and the structure of the sliding connection is not specifically limited herein.

[0090] In summary, the working principle of the operating mechanism 100 provided in the embodiment is as follows:

[0091] When the common power supply is abnormal, the driving member 171 drives the connecting shaft 172 to rotate in the second direction y, driving the dial 121 and the rotating member 161 to rotate in the second direction y synchronously, the dialing part 1212 abuts against the first stress part 1224 on the side of the first pawl 122 close to the second pawl 123 along the first groove 1223, driving the first pawl 122 to move in the direction close to the second pawl 123 under the guidance of the first straight hole 1111, so that the first driving member 131 moves in the direction close to the second driving member 132 under the guidance of the first arc-shaped hole 1113 and the fifth arc-shaped hole 1123, to drive the first driven member 133 to move in the direction close to the second driven member 134 under the guidance of the third arc-shaped hole 1121 through the first elastic member 1411, so as to realize that the first driven member 133 drives the movable contact on the side of the common power supply to open; as the dial 121 continues to rotate in the second direction y, the dialing part 1212 slides out of the first groove 1223 and is located between the first pawl 122 and the second pawl 123, at this time, the operating mechanism 100 is in a double-opening state, that is, the common power supply is opened, and the standby power supply is opened; as the dial 121 further rotates in the second direction y, the dialing part 1212 slides into the second groove 1233 and abuts against the second stress part 1234 on the side of the second pawl 123 away from the first pawl 122 along the second groove 1233, driving the second pawl 123 to move in the direction away from the first pawl 122 under the guidance of the second straight hole 1112, so that the second driving member 132 moves in the direction away from the first driving member 131 under the guidance of the second arc-shaped hole 1114 and the sixth arc-shaped hole 1124, to drive the second driven member 134 to move in the direction away from the first driven member 133 under the guidance of the fourth arc-shaped hole 1122 through the second elastic member 1412, when the second driving member 132 moves to a certain position, the second elastic member 1412 is stretched to store energy, and this state is the pre-closing of the standby power supply; after the second driving member 132 further moves so that the second elastic member 1412 is stretched to a certain extent, the second driven member 134 is instantaneously driven by the second elastic member 1412 from one end of the fourth arc-shaped hole 1122 close to the third arc-shaped hole 1121 to the other end of the fourth arc-shaped hole 1122 away from the third arc-shaped hole 1121, completing the closing of the standby power supply; at this time, the indicating member 180 triggers the second micro switch 146 to disconnect the power supply of the driving member 171 by the standby power supply, and the position of the indicating member 180 indicates that the operating mechanism 100 is in a standby closing state, and at the same time, the first driven member 133 slides out of the third groove 184 and abuts against the third stress part 181, realizing the protection function.

[0092] When the normal power supply is restored, the driving member 171 drives the connecting shaft 172 to rotate in the first direction x, thereby driving the dial 121 and the rotating member 161 to rotate in the first direction x synchronously, the driving part 1212 abuts against the second force receiving part 1234 on the side of the second pawl 123 close to the first pawl 122 along the second groove 1233, thereby driving the second pawl 123 to move in the direction close to the first pawl 122 under the guidance of the second straight hole 1112, driving the second driving member 132 to move in the direction close to the first driving member 131 under the guidance of the second arc-shaped hole 1114 and the sixth arc-shaped hole 1124, thereby driving the second driven member 134 to move in the direction close to the first driven member 133 under the guidance of the fourth arc-shaped hole 1122 through the second elastic member 1412, and realizing that the second driven member 134 drives the movable contact on the side of the standby power supply to open; as the dial 121 continues to rotate in the first direction x, the driving part 1212 slides out of the second groove 1233 and is located between the first pawl 122 and the second pawl 123, at this time, the operating mechanism 100 is in a double-opening state, that is, the normal power supply is opened, and the standby power supply is opened; as the dial 121 further rotates in the first direction x, the driving part 1212 slides into the first groove 1223 and abuts against the first force receiving part 1224 on the side of the first pawl 122 away from the second pawl 123 along the first groove 1223, thereby driving the first pawl 122 to move in the direction away from the second pawl 123 under the guidance of the first straight hole 1111, driving the first driving member 131 to move in the direction away from the second driving member 132 under the guidance of the first arc-shaped hole 1113 and the fifth arc-shaped hole 1123, thereby driving the first driven member 133 to move in the direction away from the second driven member 134 under the guidance of the third arc-shaped hole 1121 through the first elastic member 1411, and when the first driving member 131 moves to a certain position, the first elastic member 1411 is stretched to store energy, this state is the pre-closing of the normal power supply, after the first driving member 131 further moves to a certain extent, the first driven member 133 is instantaneously driven by the first elastic member 1411 from one end of the third arc-shaped hole 1121 close to the fourth arc-shaped hole 1122 to the other end of the third arc-shaped hole 1121 away from the fourth arc-shaped hole 1122, thereby completing the closing of the normal power supply, at this time, the indicating member 180 triggers the first micro switch 145 to disconnect the power supply of the driving member 171, and the position of the indicating member 180 indicates that the operating mechanism 100 is in the normal closing state, and at the same time, the second driven member 134 slides out of the fourth groove 185 and abuts against the fourth force receiving part 182, thereby realizing the protection function.

[0093] In a second aspect, the embodiments of the present application provide a dual power transfer switch, which comprises the operating mechanism 100 in any of the embodiments of the first aspect, the first driven rod is connected with the movable contact on the side of the normal power supply, for realizing the closing and opening of the normal power supply, and the second driven rod is connected with the movable contact on the side of the standby power supply, for realizing the closing and opening of the standby power supply.

[0094] It can be understood that, since the dual power transfer switch provided by the embodiment has the operating mechanism 100 in any embodiment of the first aspect, all the advantages of the operating mechanism 100 are also possessed, and thus will not be repeated here.
