[0101] For details, please refer to Figures 1 to 35 The embodiment of the present application provides an electric operation structure, including a first side plate ZCB, a central axis ZXZ, a flip lever GG01, an electric drive device and a transmission mechanism. The flip lever GG01 is rotatably mounted on the central axis ZXZ, and the flip lever GG01 is configured to drive the transfer switch to operate. The flip lever GG01 has a double-off position, corresponding to the transfer switch being in an open state. The electric drive device is mounted on the first side plate ZCB. The transmission mechanism is connected to the electric drive device and the flip lever GG01, and the transmission mechanism is configured to lock the flip lever GG01 in the double-off position and unlock the flip lever GG01 from the double-off position under the action of the electric drive device.

[0102] In this embodiment, the flip lever is rotatably mounted on the central axis, and the state of the transfer switch can be switched by the rotation of the flip lever. The electric drive device drives the transmission mechanism to move, and then the action of the transmission mechanism drives the flip lever to be locked in the double open position, so that the transfer switch can be locked in the open state. Alternatively, the action of the transmission mechanism drives the flip lever to be unlocked from the double open position, so that the transfer switch can be closed. In this way, the electric drive flip lever is locked or unlocked in the double open position.

[0103] It can be understood that the flip lever GG01 can rotate a certain angle along the central axis ZXZ. When the flip lever GG01 is at its maximum counterclockwise rotation angle position, corresponding to the flip lever GG01 being in the common side power supply closing position, the conversion switch is in the common side power supply closing state. When the flip lever GG01 is at its maximum clockwise rotation angle position, corresponding to the flip lever GG01 being in the standby side power supply closing position, the conversion switch is in the standby side power supply closing state. When the flip lever GG01 is between the maximum clockwise rotation angle position and the maximum counterclockwise rotation angle position, corresponding to the flip lever GG01 being in the double open position, the conversion switch is in the open state.

[0104] Among them, Fig. 27 The direction indicated by the arrow in the figure is the clockwise direction in the embodiments of the present application, and the opposite direction is the counterclockwise direction. The following embodiments define the clockwise direction and the counterclockwise direction in this direction. Figure 1 As shown, a spatial rectangular coordinate system is established, and the X-axis, Y-axis and Z-axis are determined. The rotation direction is subsequently described based on the orientation of the coordinate system.

[0105] The transmission mechanism and the electric drive device are used to lock the flip lever GG01 in the double open position, so that the transfer switch is locked in the open state. The transmission mechanism and the electric drive device are also used to unlock the flip lever GG01 from the double open position, so that the flip lever GG01 can be switched from the double open position to the common side power supply closing position or the standby side power supply closing position, so that the transfer switch can be in the common side power supply closing state or the standby side power supply closing state.

[0106] In some embodiments, the transmission mechanism includes a second bracket ZJ02. The second bracket ZJ02 is rotatably mounted on the first side plate ZCB, and the second bracket ZJ02 is configured with a bracket limiting axis Z23, which is configured to lock the flip lever GG01 in the double-open position and unlock the flip lever GG01 from the double-open position under the action of the electric drive device.

[0107] It can be understood that by rotatably mounting the second bracket ZJ02 on the first side plate ZCB, the second bracket ZJ02 can lock the position of the flip lever GG01 or unlock the position of the flip lever GG01. Specifically, the second bracket ZJ02 can have a first rotation position and a second rotation position. In the first rotation position, the bracket limit axis Z23 of the second bracket ZJ02 locks the flip lever GG01 in the double position. In the second rotation position, the bracket limit axis Z23 of the second bracket ZJ02 is away from the flip lever GG01 to unlock the position of the flip lever GG01.

[0108] like Fig.12As shown, the second bracket ZJ02 is provided with a bracket reset portion ZJ02.3, the first side plate ZCB is provided with a second spring mounting shaft Z06a, and the two ends of the second spring TH03a are respectively connected to the bracket reset portion ZJ02.3 and the second spring mounting shaft Z06a. When the second bracket ZJ02 locks the flip lever GG01 to the double-open position, the second spring TH03a is in a stretched state or an initial state. So that after the second bracket ZJ02 rotates, the second spring TH03a can provide the second bracket ZJ02 with a pulling force for rotation reset.

[0109] In some embodiments, the transmission mechanism further comprises a second lever GG07. The second lever GG07 is rotatably mounted on the first side plate ZCB, and the second lever GG07 is used to abut against the flip lever limit axis Z13 of the flip lever GG01 to lock the flip lever GG01 in the double position, wherein the bracket limit axis Z23 is suitable for abutting against the second lever GG07 to lock the position of the second lever GG07.

[0110] The flip lever GG01 is locked or unlocked in the double split position by the second lever GG07. When the second bracket ZJ02 is in the first rotation position, the bracket limit axis Z23 abuts against the second lever GG07 to lock the position of the second lever GG07. After the position of the second lever GG07 is locked, the second lever GG07 abuts against the flip lever limit axis Z13 of the flip lever GG01, and the second lever GG07 can lock the position of the flip lever GG01 to achieve locking the flip lever GG01 in the double split position. When the second bracket ZJ02 is in the second rotation position, the bracket limit axis Z23 is away from the second lever GG07, so that the second lever GG07 is in a freely rotatable state. Based on the free rotation of the second lever GG07, the second lever GG07 will not limit the movement of the flip lever limit axis Z13 of the flip lever GG01, so that the position of the flip lever GG01 can be rotated, so as to achieve unlocking the flip lever GG01 from the double split position.

[0111] The transmission mechanism also includes a first bracket ZJ01. The first bracket ZJ01 is mounted on the first side plate ZCB, the first bracket ZJ01 is configured with a fourth slot ZJ01.3, the second lever GG07 is rotatably mounted on the first side plate ZCB or the first bracket ZJ01, the second bracket ZJ02 is rotatably mounted on the first bracket ZJ01, the bracket limit axis Z23 is passed through the fourth slot ZJ01.3, and the portion of the bracket limit axis Z23 passing through the fourth slot ZJ01.3 is configured to abut against the second lever GG07 to lock the position of the second lever GG07.

[0112] The first bracket ZJ01 is used to rotatably mount the second bracket ZJ02. The first bracket ZJ01 is fixedly mounted on the first side plate ZCB, thereby realizing the rotatable connection between the second bracket ZJ02 and the first side plate ZCB. Fig.11 As shown, the first bracket ZJ01 may be constructed with a plurality of side panel mounting parts ZJ01.1, and the plurality of side panel mounting parts ZJ01.1 are respectively connected to the fifth lever mounting axis Z24 of the first side panel ZCB to realize the fixed installation between the first bracket ZJ01 and the first side panel ZCB. The first bracket ZJ01 is also constructed with a first bracket mounting part ZJ01.2, and the first bracket mounting part ZJ01.2 cooperates with the second bracket mounting part ZJ02.2 of the second bracket ZJ02 to rotatably install the second bracket ZJ02. Among them, the fourth notch ZJ01.3 on the first bracket ZJ01 is arc-shaped, and the center of the fourth notch ZJ01.3 corresponds to the first bracket mounting part ZJ01.2, so that the bracket limiting axis Z23 on the second bracket ZJ02 can take the first bracket mounting part ZJ01.2 as the center and slide along the fourth notch ZJ01.3. The curvature of the fourth notch ZJ01.3 is selected based on actual needs to ensure that when the first bracket ZJ01 is in the first rotation position, the bracket limit axis Z23 abuts against the second lever GG07, and when the first bracket ZJ01 is in the second rotation position, the bracket limit axis Z23 is away from the second lever GG07.

[0113] like Fig.11 and Fig.12 As shown, based on the second bracket ZJ02 being rotatably installed on the inner side of the first bracket ZJ01, the bracket limiting axis Z23 of the second bracket ZJ02 is passed through the fourth slot ZJ01.3 of the first bracket ZJ01 so that the bracket limiting axis Z23 can abut against the second lever GG07, so as to realize the position locking of the second lever GG07 through the bracket limiting axis Z23.

[0114] In some embodiments, the electric drive device is a second electromagnet CT2, and the second electromagnet CT2 includes a second yoke CT2.1, a second return spring CT2.3 and a second iron core CT2.2. The second yoke CT2.1 is configured with a second mounting cavity, and a second telescopic opening communicating with the second mounting cavity is configured on the side of the second yoke CT2.1 facing the second bracket ZJ02. The second return spring CT2.3 is disposed in the second mounting cavity. The second iron core CT2.2 is disposed in the second mounting cavity, one end of the second iron core CT2.2 is connected to the second return spring CT2.3, and the other end of the second iron core CT2.2 passes through the second mounting cavity from the second telescopic opening, wherein the second iron core CT2.2 is suitable for being driven by an external force to move in the direction of the second bracket ZJ02 to drive the second bracket ZJ02 to rotate, and the second iron core CT2.2 is suitable for being driven by the second return spring CT2.3 to move in the direction of the second mounting cavity.

[0115] like Fig.14 As shown, the second magnetic yoke CT2.1 serves as the outer frame of the second electromagnet CT2. A second mounting cavity is constructed in the second magnetic yoke CT2.1, so that the second reset spring CT2.3 and the second iron core CT2.2 can be installed in the second mounting cavity. Among them, the second iron core CT2.2 can move toward the direction of the second bracket ZJ02 when the power is turned on, so as to abut against the bracket linkage part ZJ02.1 of the second bracket ZJ02, so as to drive the second bracket ZJ02 to rotate. The second iron core CT2.2 can move toward the direction of the second mounting cavity when the power is turned off, so as to be retracted into the second mounting cavity. At the same time, the second bracket ZJ02 resumes rotation under the action of the second spring TH03a.

[0116] Among them, based on the structural design of the second electromagnet CT2, the electric control of unlocking in the double-open position can be realized, making the unlocking operation at the double-open position simpler and more reliable. At the same time, based on the second electromagnet CT2, the flip lever GG01 can be locked and unlocked in the area between the common side power closing position and the standby side power closing position, thereby making the flip lever GG01 have a double-open position, which can avoid misoperation and prevent the flip lever GG01 from directly switching from the common side power closing position to the standby side power closing position, or prevent the flip lever GG01 from directly switching from the standby side power closing position to the common side power closing position, thereby improving the stability and safety of the state switching process.

[0117] In some embodiments, the electric drive device further includes a second spring TH03a. The second spring TH03a is connected between the second bracket ZJ02 and the first side plate ZCB, and the second spring TH03a is configured to drive the second bracket ZJ02 to rotate and reset.

[0118] It is understandable that the movement of the second iron core CT2.2 can drive the second bracket ZJ02 to rotate, thereby unlocking the flip lever GG01 from the double-open position. After unlocking, in order to achieve subsequent reuse, the second bracket ZJ02 needs to be able to rotate and reset to the initial state. Therefore, the second bracket ZJ02 and the first side plate ZCB are connected by the second spring TH03a, so that after the force of the second iron core CT2.2 on the second bracket ZJ02 is removed, the second bracket ZJ02 can be rotated and reset.

[0119] Based on the above structure, it is possible to lock the flip lever GG01 in the double-open position or unlock the flip lever GG01 from the double-open position during the electric driving process. The details are as follows:

[0120] like Fig.30 a and Fig.30As shown in FIG. 2 , when the transfer switch is in the state of closing the power supply on the common side, the flip lever GG01 is in the maximum angle position of its counterclockwise rotation, and the flip lever limit axis Z13 is in contact with the second stopper GG07.2. At this time, the second lever GG07 is in the maximum angle position of its clockwise rotation, and the fourth stopper GG07.4 is located on the left side of the bracket limit axis Z23. Due to the action of the second spring TH03a, the second bracket ZJ02 is positioned at the maximum angle position of its counterclockwise rotation. The second iron core CT2.2 retracts into the second mounting cavity under the action of the second reset spring CT2.3, so that the second iron core CT2.2 is away from the second bracket ZJ02.

[0121] like Fig.31 a and Fig.31 As shown in FIG. 2 , when the transfer switch starts to open from the common side power supply, the flip lever GG01 will rotate clockwise, and the flip lever limit axis Z13 will gradually move away from the second stopper GG07.2 and abut against the first stopper GG07.1. When the flip lever GG01 rotates to the double-off position, it still has a tendency to continue to rotate clockwise, and the second lever GG07 has a tendency to rotate counterclockwise. At this time, the third stopper GG07.3 abuts against the bracket limit axis Z23, and the flip lever GG01 is locked in the double-off position.

[0122] like Fig.32 a to Fig.32 c, after the second electromagnet CT2 is energized, the second iron core CT2.2 can move toward the second bracket ZJ02, and the second iron core CT2.2 can abut against the second bracket ZJ02 and drive the second bracket ZJ02 to rotate clockwise. At this time, the bracket limit axis Z23 gradually moves away from the third stopper GG07.3, and the second lever GG07 is released from the limit.

[0123] like Fig.33 a and Fig.33 As shown in FIG. 2 b, after the second lever GG07 is released from the limit, the flip lever GG01 rotates clockwise to the standby side power supply closing position, corresponding to the counterclockwise rotation of the second lever GG07, and the second lever GG07 is finally located at the maximum angle position of its counterclockwise rotation. After the second electromagnet CT2 is powered off, the second iron core CT2.2 will be retracted into the second installation cavity under the action of the second reset spring CT2.3. Due to the action of the second spring TH03a, the second bracket ZJ02 is reset and positioned at the maximum angle position of its counterclockwise rotation. At this time, the third stopper GG07.3 is located on the right side of the bracket limit axis Z23.

[0124] From the above process, it can be known that the flip lever GG01 can be switched from the common side power on position to the double off position by electric drive, and locked in the double off position, and then switched to the standby side power on position after unlocking from the double off position. This is to achieve the switching of the transfer switch from the common side on state to the double off state, and then to the standby side on state. If it is necessary to complete the switching from the common side power on position to the double off position, and then switch from the double off position back to the common side power on position, the first electromagnet CT1 is energized.

[0125] like Fig.33 a and Fig.33 As shown in FIG. 2 b, when the transfer switch is in the standby power supply closing state, the flip lever GG01 is in its maximum clockwise rotation angle position, and the flip lever limit axis Z13 is in contact with the first stopper GG07.1. At this time, the second lever GG07 is in its maximum counterclockwise rotation angle position, and the third stopper GG07.3 is located on the right side of the bracket limit axis Z23. Due to the action of the second spring TH03a, the second bracket ZJ02 is positioned at its maximum counterclockwise rotation angle position. The second iron core CT2.2 retracts into the second mounting cavity under the action of the second reset spring CT2.3, so that the second iron core CT2.2 is away from the second bracket ZJ02.

[0126] like Fig.34 a to Fig.34 As shown in FIG. 3 , when the transfer switch starts to open from the backup power supply, the flip lever GG01 will rotate counterclockwise, and the flip lever limit axis Z13 will gradually move away from the first stop GG07.1 and abut against the second stop GG07.2. When the flip lever GG01 rotates to the double-off position, it still has a tendency to continue to rotate counterclockwise, and makes the second lever GG07 have a tendency to rotate clockwise. At this time, the third stop GG07.3 abuts against the bracket limit axis Z23, and the flip lever GG01 is locked in the double-off position.

[0127] like Fig.35 a and Fig.35 As shown in FIG. 2 , after the second electromagnet CT2 is energized, the second iron core CT2.2 can move toward the second bracket ZJ02, and the second iron core CT2.2 abuts against the second bracket ZJ02 and drives the second bracket ZJ02 to rotate clockwise. At this time, the bracket limit axis Z23 gradually moves away from the third stopper GG07.3, and the second lever GG07 is released from the limit.

[0128] like Fig.30 a and Fig.30As shown in FIG. 2 , after the second lever GG07 is released from the limit, the flip lever GG01 rotates counterclockwise to the power-on position on the common side, corresponding to the clockwise rotation of the second lever GG07, and the second lever GG07 is finally located at the maximum angle position of its clockwise rotation. After the second electromagnet CT2 is powered off, the second iron core CT2.2 will be retracted into the second installation cavity under the action of the second reset spring CT2.3. Due to the action of the second spring TH03a, the second bracket ZJ02 is reset and positioned at the maximum angle position of its counterclockwise rotation, and the third stopper GG07.3 is located on the left side of the bracket limit axis Z23.

[0129] From the above process, it can be known that the flip lever GG01 can be switched from the standby side power supply closing position to the double open position by electric drive, and locked in the double open position, and then switched to the common side power supply closing position after unlocking from the double open position. This is to achieve the switching of the transfer switch from the standby side closing state to the double open state, and then to the common side closing state. If you need to complete the switching from the standby side power supply closing position to the double open position, and then switch from the double position back to the standby side power supply closing position, just energize the first electromagnet CT1.

[0130] In some embodiments, the electric operation structure further includes a first lever GG05, a connecting rod LG01 and a first electromagnet CT1. The first lever GG05 is connected to the central axis ZXZ and drives the central axis ZXZ to rotate. The first lever GG05 is configured with a third slot GG05.2, and the two ends of the third slot GG05.2 are respectively configured with a first slot section GG05.2.1 and a third slot section GG05.2.3. The opposite sides of the connecting rod LG01 are respectively configured with a first linkage part LG01.1 and a second linkage part LG01.2, and the first linkage part LG01.1 is slidably mounted on the third slot GG05.2. The first electromagnet CT1 is rotatably connected to the second linkage part LG01.2, and is used to drive the connecting rod LG01 to move, so that the first linkage part LG01.1 acts on the first slot section GG05.2.1 or the third slot section GG05.2.3 to drive the first lever GG05 to rotate.

[0131] like Figure 8 As shown, the first lever GG05 is provided with a mounting portion GG05.1, which is a non-circular structure, and is connected to the first section ZXZ.1 of the central axis ZXZ. The two are engaged with each other, so that the first lever GG05 and the central axis ZXZ do not slide relative to each other, so that the central axis ZXZ can be driven to rotate by the rotation of the first lever GG05.

[0132] The third slot GG05.2 of the first lever GG05 is arranged along its length direction, and the first slot section GG05.2.1 and the third slot section GG05.2.3 are arranged at both ends of the third slot GG05.2 and are respectively located on opposite sides of the axis of the first electromagnet CT1. Among them, the first slot section GG05.2.1 and the third slot section GG05.2.3 both extend in the direction of the first electromagnet CT1, so that the first slot section GG05.2.1 and the third slot section GG05.2.3 can both have a certain length. The first linkage part LG01.1 can slide in the third slot GG05.2 and then abut against the first slot section GG05.2.1, and based on the external force, the first linkage part LG01.1 abuts against the end of the first slot section GG05.2.1 close to the first electromagnet CT1 or the end away from the first electromagnet CT1. Therefore, based on the arrangement of the third notch GG05.2, after the first electromagnet CT1 drives the connecting rod LG01 to swing, the connecting rod LG01 can drive the first lever GG05 to rotate reciprocatingly clockwise and counterclockwise.

[0133] The first electromagnet CT1 is used as a driving component for the reciprocating rotation of the first lever GG05. It drives the first iron core CT1.2 inside the driver to move by powering on, and it drives the first reset spring CT1.3 to reset the first iron core CT1.2 by powering off. The first iron core CT1.2 is connected to the second linkage part LG01.2, thereby realizing the driving of the connecting rod LG01 by the first electromagnet CT1.

[0134] It can be seen that only one first electromagnet CT1 can be provided, and the unidirectional reciprocating motion of the first electromagnet CT1 can be used to drive the first lever GG05 to rotate clockwise (forward) and counterclockwise (reverse), so as to realize the forward and reverse rotation of the central axis ZXZ. In the related art, two electromagnets are usually used to realize the forward and reverse rotation of the central axis ZXZ, one electromagnet is used to realize the forward rotation, and the other electromagnet is used to realize the reverse rotation. In this embodiment, only one first electromagnet CT1 is used to realize the forward and reverse rotation of the central axis ZXZ, which can save one electromagnet, thereby reducing the production cost.

[0135] At the same time, since the central axis ZXZ is driven to rotate forward and reverse only by a first electromagnet CT1 in cooperation with mechanical transmission, and since the stability of mechanical transmission is greater than the stability of electronic control transmission, the reliability of the operating mechanism can be improved and misoperation can be well prevented.

[0136] like Fig. 9As shown, the connecting rod LG01 has two plates arranged opposite to each other, and the two plates are connected by a connecting shaft. A second linkage part LG01.2 is formed at one end of each of the two plates, so as to be rotatably connected to the first electromagnet CT1 through the second linkage part LG01.2. The other ends of the two plates rotate the first linkage part LG01.1 between the two plates, so that the first linkage part LG01.1 is slidably arranged in the third notch GG05.2, and based on the limit of the two plates, the first linkage part LG01.1 is prevented from falling off from the third notch GG05.2.

[0137] In some embodiments, the first electromagnet CT1 includes a first yoke CT1.1, a first return spring CT1.3 and a first iron core CT1.2. The first yoke CT1.1 is configured with a first mounting cavity, and a first telescopic opening communicating with the first mounting cavity is configured on the side of the first yoke CT1.1 facing the connecting rod LG01. The first return spring CT1.3 is disposed in the first mounting cavity. The first iron core CT1.2 is disposed in the first mounting cavity, one end of the first iron core CT1.2 is connected to the first return spring CT1.3, and the other end of the first iron core CT1.2 passes through the first mounting cavity from the first telescopic opening and is rotatably connected to the second linkage part LG01.2, wherein the first iron core CT1.2 is suitable for being driven by the first return spring CT1.3 to move in the direction of the second linkage part LG01.2, and the first iron core CT1.2 is suitable for being driven by an external force to move in the direction of the first mounting cavity.

[0138] It can be understood that the first magnetic yoke CT1.1 is fixedly mounted on the first side plate ZCB, the first magnetic yoke CT1.1 is an outer frame, and a first installation cavity is constructed in the first magnetic yoke CT1.1, so that the first reset spring CT1.3 and the first iron core CT1.2 can be installed in the first installation cavity. Among them, the first iron core CT1.2 can be moved toward the direction of the first installation cavity when the power is on, so that the first iron core CT1.2 can be retracted into the first installation cavity. The first iron core CT1.2 can be moved toward the direction of the second linkage part LG01.2 when the power is off, so that it can drive the second linkage part LG01.2 to swing. And the second linkage part LG01.2 is restored to rotation under the action of the first reset spring CT1.3 and the first spring TH04.

[0139] In some embodiments, the first iron core CT1.2 is connected to the first spring TH04 at the portion passing through the first telescopic opening, and the other end of the first spring TH04 is connected to the first spring mounting axis Z18 of the connecting rod LG01. The force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04.

[0140] The force value Fj of the first return spring CT1.3 refers to the force of the first return spring CT1.3 on the connecting rod LG01, and the force value Ft of the first spring TH04 refers to the force of the first spring TH04 on the connecting rod LG01.

[0141] The first iron core CT1.2 passes through the first telescopic opening and is structured with a first spring mounting position CT1.2.2 and a first magnet linkage position CT1.2.1. The first spring mounting position CT1.2.2 is used to connect the first spring TH04, and the first magnet linkage position CT1.2.1 is used to rotate the second linkage part LG01.2 of the connecting rod LG01. The first magnet linkage position CT1.2.1 is arranged close to the first lever GG05, and the first spring mounting position CT1.2.2 is arranged away from the first lever GG05, so that the distance between the first spring mounting position CT1.2.2 and the first lever GG05 is greater than the distance between the first magnet linkage position CT1.2.1 and the first lever GG05.

[0142] The first return spring CT1.3 is in a contracted state, and can provide a thrust to the connecting rod LG01 through the first iron core CT1.2 to move toward the first lever GG05. The first spring TH04 is in a stretched state, and provides a pulling force to the connecting rod LG01 to move away from the first lever GG05. Since the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04, the force of the first return spring CT1.3 on the connecting rod LG01 can be greater than the force of the first spring TH04 on the connecting rod LG01, so as to cooperate with the arrangement of the third notch GG05.2 of the first lever GG05, so as to realize the reciprocating clockwise and counterclockwise rotation of the first lever GG05.

[0143] like Fig.19 and Fig.24As shown, the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04, including: when the first iron core CT1.2 is retracted into the first installation cavity, the elastic force Fj applied by the first return spring CT1.3 to the connecting rod LG01 is greater than the elastic force Ft applied by the first spring TH04 to the connecting rod LG01. And / or, when the first return spring CT1.3 and the first spring TH04 drive the first linkage part LG01.1 to switch from abutting the first approaching end GG05.2.1b to abutting the first remote end GG05.2.1a, the elastic force Fj applied by the first return spring CT1.3 to the connecting rod LG01 is still greater than the elastic force Ft applied by the first spring TH04 to the connecting rod LG01. And / or, after the first return spring CT1.3 and the first spring TH04 drive the first linkage part LG01.1 to switch from abutting the second close end GG05.2.3b to abutting the second far end GG05.2.3a, the elastic force Fj applied by the first return spring CT1.3 to the connecting rod LG01 is still greater than the elastic force Ft applied by the first spring TH04 to the connecting rod LG01. And / or, the elastic force Fj applied by the first return spring CT1.3 to the connecting rod LG01 is greater than the elastic force Ft applied by the first spring TH04 to the connecting rod LG01 in any state.

[0144] In some embodiments, the first slot segment GG05.2.1 has a first close end GG05.2.1b recessed toward the first iron core CT1.2 and a first far end GG05.2.1a away from the first iron core CT1.2. When the first return spring CT1.3 and the first spring TH04 drive the first linkage part LG01.1 to switch from abutting the first close end GG05.2.1b to abutting the first far end GG05.2.1a, an angle A is formed between the line connecting the first linkage part LG01.1 and the second linkage part LG01.2 and the third slot GG05.2, wherein 90°<A<180°.

[0145] It can be understood that, since 90°<A<180°, and the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04, if the force Fj and Ft are decomposed along the extension direction of the third notch GG05.2, there will be a resultant force downward along the extension direction of the third notch GG05.2. Thus, the first linkage part LG01.1 of the connecting rod LG01 can slide downward along the third notch GG05.2.

[0146] In some embodiments, the third slot segment GG05.2.3 has a second proximal end GG05.2.3b recessed toward the first iron core CT1.2 and a second distal end GG05.2.3a distal to the first iron core CT1.2. When the first return spring CT1.3 and the first spring TH04 drive the first linkage part LG01.1 to switch from abutting the second proximal end GG05.2.3b to abutting the second distal end GG05.2.3a, an angle B is formed between the line connecting the first linkage part LG01.1 and the second linkage part LG01.2 and the third slot GG05.2, wherein 90°<B<180°.

[0147] It can be understood that, since 90°<B<180°, and the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04, if the force Fj and Ft are decomposed along the extension direction of the third notch GG05.2, there will be a combined force upward along the extension direction of the third notch GG05.2. Thus, the first linkage part LG01.1 of the connecting rod LG01 can slide upward along the third notch GG05.2.

[0148] Based on the above structure, the first lever GG05 can be driven to rotate forward and reverse. The details are as follows:

[0149] like Fig.15 As shown, when the transfer switch is in the state of closing the power supply on the common side, the first lever GG05 is driven to be at the maximum angle position of its clockwise rotation. Due to the action of the first return spring CT1.3, the first iron core CT1.2 is located at the maximum movement stroke position in the direction of the second linkage part LG01.2. The first iron core CT1.2 drives the connecting rod LG01 to make the first linkage part LG01.1 located in the first groove section GG05.2.1. At the same time, under the action of the first spring TH04, the first linkage part LG01.1 will abut against the first remote end GG05.2.1a.

[0150] like Fig.16 As shown, when the first electromagnet CT1 is energized, the first iron core CT1.2 moves toward the first mounting cavity, causing the connecting rod LG01 to move to the left. Due to the action of the first spring TH04, the first linkage part LG01.1 switches from abutting the first distal end GG05.2.1a to abutting the first proximal end GG05.2.1b. Fig.17 As shown, when the first iron core CT1.2 continues to move toward the first installation cavity, the connecting rod LG01 can rotate the first lever GG05 counterclockwise, and the first lever GG05 finally rotates to its maximum counterclockwise rotation angle position.

[0151] like Fig.18As shown, when the first iron core CT1.2 moves to the maximum movement forming position in the first installation cavity, the first lever GG05 rotates to its maximum counterclockwise rotation angle position and is locked in this position. At this time, the first electromagnet CT1 is powered off, and the first iron core CT1.2 is reset in the direction of the second linkage part LG01.2 under the action of the first reset spring CT1.3. At the same time, under the joint action of the first spring TH04, the first linkage part LG01.1 switches from abutting the first distal end GG05.2.1b to abutting the first proximal end GG05.2.1a. At this time, the line connecting the first linkage part LG01.1 and the second linkage part LG01.2 forms an angle A with the third notch GG05.2.

[0152] like Fig.19 As shown in the figure, since 90°<A<180°, and the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04. Along the extension direction of the third notch GG05.2, the force of the first return spring CT1.3 on the connecting rod LG01 will be much greater than the force of the first spring TH04 on the connecting rod LG01. As a result, the first linkage part LG01.1 of the connecting rod LG01 slides downward along the third notch GG05.2. Fig. 20 As shown, after the first linkage portion LG01.1 of the connecting rod LG01 slides downward along the third notch GG05.2, it will eventually abut against the second distal end GG05.2.3a of the third groove section GG05.2.3.

[0153] like Fig.21 As shown, the first electromagnet CT1 is energized again, and the first iron core CT1.2 moves toward the first installation cavity, causing the connecting rod LG01 to move to the left. Due to the action of the first spring TH04, the first linkage part LG01.1 switches from abutting the second distal end GG05.2.3a to abutting the second proximal end GG05.2.3b. Fig. 22 As shown, when the first iron core CT1.2 continues to move toward the first installation cavity, the connecting rod LG01 can rotate the first lever GG05 clockwise, and the first lever GG05 finally rotates to its maximum clockwise rotation angle position.

[0154] like Fig.23As shown, when the first iron core CT1.2 moves to the maximum movement stroke position in the direction of the second linkage part LG01.2, the first lever GG05 rotates to the maximum angle position of its clockwise rotation and is positioned at this position. At this time, the first electromagnet CT1 is powered off, and the first iron core CT1.2 is reset in the direction of the second linkage part LG01.2 under the action of the first reset spring CT1.3. At the same time, under the joint action of the first spring TH04, the first linkage part LG01.1 switches from abutting the second far end GG05.2.3b to abutting the second close end GG05.2.3a. At this time, the line connecting the first linkage part LG01.1 and the second linkage part LG01.2 forms an angle B with the third notch GG05.2.

[0155] like Fig.24 As shown in the figure, since 90°<B<180°, and the force value Fj of the first return spring CT1.3 is greater than the force value Ft of the first spring TH04. Along the extension direction of the third notch GG05.2, the force of the first return spring CT1.3 on the connecting rod LG01 will be much greater than the force of the first spring TH04 on the connecting rod LG01. As a result, the first linkage part LG01.1 of the connecting rod LG01 slides upward along the third notch GG05.2. Fig.15 As shown, after the first linkage portion LG01.1 of the connecting rod LG01 slides upward along the third notch GG05.2, it will eventually abut against the first distal end GG05.2.1a of the first groove section GG05.2.1.

[0156] From the above process, it can be known that the first lever GG05 can be driven to rotate clockwise or counterclockwise by controlling the power on and off of the first electromagnet CT1, so that the unidirectional motion of the first iron core CT1.2 can be converted into the reciprocating clockwise and counterclockwise rotation of the first lever GG05.

[0157] Since the center axis ZXZ is controlled by the first lever GG05, the center axis ZXZ can reciprocate clockwise and counterclockwise.

[0158] In some embodiments, the electric operation structure further includes a first flip plate B02. The first flip plate B02 is mounted on the central axis ZXZ and rotates with the central axis ZXZ, and a first mounting assembly is disposed on the first flip plate B02. A second mounting assembly is configured on the flip lever GG01, wherein a spring assembly is connected between the first mounting assembly and the second mounting assembly, and the spring assembly is configured to drive the flip lever GG01 to rotate along the central axis ZXZ.

[0159] The first flip plate B02 is mounted on the central axis ZXZ and rotated along with the central axis ZXZ. When the first lever GG05 drives the central axis ZXZ to rotate, the central axis ZXZ can drive the first flip plate B02 to rotate. Figure 5As shown, a first flip plate mounting portion B02.1 is constructed in the middle of the first flip plate B02. The first flip plate mounting portion B02.1 is a non-circular structure, which can be mounted on the fifth segment ZXZ.5 of the central axis ZXZ.

[0160] A spring assembly is connected between the first mounting assembly and the second mounting assembly of the first flip plate B02. The spring assembly can be compressed and continuously store energy based on the rotation of the first flip plate B02. When the first flip plate B02 rotates to a certain extent to release energy of the spring assembly, the spring assembly will drive the flip lever GG01 to flip, so that the flip lever GG01 switches its position.

[0161] Therefore, the flip lever GG01 can be driven to rotate from the normal side power closing position to the double open position or the standby side power closing position by rotating the center axis ZXZ; the flip lever GG01 can also be driven to rotate from the standby side power closing position to the double open position or the normal side power closing position; the flip lever GG01 can also be driven to rotate from the double open position to the normal side power closing position or the standby side power closing position.

[0162] In some embodiments, when the first mounting component, the second mounting component and the center axis ZXZ are in the same straight line, the flip lever GG01 is in a dead point position maintaining a stationary state, wherein the center axis ZXZ is suitable for driving the first flip plate B02 to rotate so that the flip lever GG01 passes the dead point position, and after passing the dead point position, the flip lever GG01 is driven to rotate by the spring assembly.

[0163] It can be understood that when the first flip plate B02 is driven to rotate by the central axis ZXZ, when the first flip plate B02 rotates to a specific position, the first mounting assembly, the second mounting assembly and the central axis ZXZ will be in the same straight line. At this time, the flip lever GG01 is in a balanced state, the flip lever GG01 remains stationary and the position is defined as the dead point position of the flip lever GG01.

[0164] When the flip lever GG01 is at the dead point, the central axis ZXZ continues to rotate, and the rotation of the central axis ZXZ drives the first flip plate B02 to rotate, thereby breaking the force balance of the flip lever GG01. At this time, the spring assembly can release the elastic force formed by its own compression, thereby driving the flip lever GG01 to rotate.

[0165] In some embodiments, the first mounting assembly includes a first flip spring fixing portion B02.2 and a second flip spring fixing portion B02.3 spaced apart on the first flip plate B02, the second mounting assembly includes a first flip spring mounting portion GG01.2 and a second flip spring mounting portion GG01.3 constructed on both sides of the flip lever GG01, and the spring assembly includes a first flip spring TH01 and a second flip spring TH01'. The first flip plate B02 is located between the first flip spring mounting portion GG01.2 and the second flip spring mounting portion GG01.3, the first flip spring TH01 is connected between the first flip spring mounting portion GG01.2 and the first flip spring fixing portion B02.2, the second flip spring TH01' is connected between the second flip spring mounting portion GG01.3 and the second flip spring fixing portion B02.3, and the first flip spring TH01 and the second flip spring TH01' are configured to drive the flip lever GG01 to rotate along the central axis ZXZ.

[0166] It can be understood that the first flip spring fixing portion B02.2 and the second flip spring fixing portion B02.3 are symmetrically distributed along the axis of the first flip plate B02. The first flip spring TH01 and the second flip spring TH01' are symmetrically connected to the two sides of the first flip plate B02. The first flip spring mounting portion GG01.2 and the second flip spring mounting portion GG01.3 are symmetrically arranged on both sides of the length direction of the flip lever GG01. When the center axis ZXZ drives the first flip plate B02 to rotate, the first flip spring TH01 and the second flip spring TH01' are synchronously compressed and store energy synchronously. At the dead point position, the compression of the first flip spring TH01 and the second flip spring TH01' is the largest. When the center axis ZXZ is further rotated to drive the first flip plate B02 to rotate, the first flip spring TH01 and the second flip spring TH01' can release the elastic force formed by their own compression, thereby driving the flip lever GG01 to rotate.

[0167] like Figure 7 As shown, the flip lever GG01 includes two plates arranged opposite to each other, and the two ends of the two plates in the length direction are connected by the first flip spring mounting part GG01.2 and the second flip spring mounting part GG01.3 respectively. The middle of the two plates is respectively configured with a flip lever mounting hole GG01.1, and the fourth section ZXZ.4 of the central axis ZXZ is rotatably connected through the flip lever mounting hole GG01.1. The flip lever limit axis Z13 is set on the plate close to the first side plate ZCB.

[0168] In some embodiments, when the first flip spring installation part GG01.2, the first flip spring fixing part B02.2, the second flip spring fixing part B02.3 and the second flip spring installation part GG01.3 are located in the same straight line, the flip lever GG01 is at a dead point position. The central axis ZXZ is suitable for driving the first flip plate B02 to rotate so that the flip lever GG01 passes the dead point position, and after passing the dead point position, the first flip spring TH01 and the second flip spring TH01' drive the flip lever GG01 to rotate.

[0169] It can be understood that, in the process of driving the first flip plate B02 to rotate through the central axis ZXZ, when the first flip plate B02 rotates to a specific position, the first flip spring mounting portion GG01.2, the first flip spring fixing portion B02.2, the second flip spring fixing portion B02.3 and the second flip spring mounting portion GG01.3 will be in the same straight line, and the axes of the first flip spring TH01, the second flip spring TH01' and the flip lever GG01 will also be on the straight line. At this time, the force on the flip lever GG01 is in a balanced state, making it in a dead point position. Then continue to rotate the central axis ZXZ to break the force balance of the flip lever GG01. At this time, the first flip spring TH01 and the second flip spring TH01' can release the elastic force formed by their own compression, thereby driving the flip lever GG01 to rotate.

[0170] In some embodiments, the flip lever GG01 also has a common side power supply closing position and a standby side power supply closing position, corresponding to the switching switch being in the common side power supply closing state and the standby side power supply closing state. The aforementioned double split position is located between the common side power supply closing position and the standby side power supply closing position. The first side plate ZCB is spaced apart with a first flip limit axis Z03 and a second flip limit axis Z03', and the flip lever GG01 is located between the first flip limit axis Z03 and the second flip limit axis Z03', wherein the flip lever GG01 is suitable for abutting against the first flip limit axis Z03 to position it at the common side power supply closing position, and the flip lever GG01 is suitable for abutting against the second flip limit axis Z03' to position it at the standby side power supply closing position.

[0171] The first flip limit axis Z03 is used to limit the flip lever GG01 to its maximum counterclockwise rotation angle position, so that the flip lever GG01 is positioned at the common side power switch-on position. The second flip limit axis Z03' is used to limit the flip lever GG01 to its maximum clockwise rotation angle position, so that the flip lever GG01 is positioned at the standby side power switch-on position.

[0172] The first flip limit axis Z03 and the second flip limit axis Z03' can be set to two. The two first flip limit axes Z03 respectively abut the side surfaces at the upper and lower ends of the flip lever GG01 to limit the flip lever GG01 at its maximum counterclockwise rotation angle position. The two second flip limit axes Z03' respectively abut the side surfaces at the upper and lower ends of the flip lever GG01 to limit the flip lever GG01 at its maximum clockwise rotation angle position.

[0173] Regardless of the position of the flip lever GG01, the first flip spring TH01 and the second flip spring TH01' are in a compressed state. Therefore, when the flip lever GG01 is located at the normal side power closing position or the standby side power closing position, the first flip spring TH01 and the second flip spring TH01' can also provide the flip lever GG01 with a force toward the first flip limit axis Z03 or the second flip limit axis Z03', so that the flip lever GG01 can be positioned at the normal side power closing position or the standby side power closing position.

[0174] In some embodiments, the switching device further includes a second flip plate B04 and a second side plate YCB. The second flip plate B04 is mounted on the central axis ZXZ and rotates with the central axis ZXZ. The second flip plate B04 is configured with a first flip limiter B04.2 and a second flip limiter B04.3 arranged at intervals. The second side plate YCB is configured with a second flip plate limiter axis Z10, which is configured to abut against the first flip limiter B04.2 or the second flip limiter B04.3 to position the second flip plate B04.

[0175] It can be understood that when the second flip plate limit axis Z10 abuts against the first flip limit part B04.2 or the second flip limit part B04.3, the position of the second flip plate B04 is locked by the second flip plate limit axis Z10. At this time, the second flip plate B04 cannot continue to rotate along the current rotation direction, so that the center axis ZXZ cannot continue to rotate along the current rotation direction. When the first flip spring TH01 and the second flip spring TH01' release energy, the first flip spring TH01 and the second flip spring TH01' can only drive the flip lever GG01 to rotate to make the first flip spring TH01 and the second flip spring TH01' extend, thereby realizing the flip lever GG01 abutting against the first flip limit axis Z03 or the second flip limit axis Z03', so that the flip lever GG01 can be positioned at the normal side power closing position or the standby side power closing position.

[0176] The second flip plate B04 is mounted on the central axis ZXZ and rotated along with the central axis ZXZ. When the first lever GG05 drives the central axis ZXZ to rotate, the central axis ZXZ can drive the second flip plate B04 to rotate. Figure 6As shown, a second flip plate mounting portion B04.1 is constructed in the middle of the first flip plate B02. The second flip plate mounting portion B04.1 is a non-circular structure, which can be mounted on the mounting portion ZXZ.2 of the central axis ZXZ.

[0177] The first flip limiter B04.2 and the second flip limiter B04.3 are symmetrically arranged along the axis of the second flip plate B04, so that when the second flip plate B04 is in the fixed rotation position, the first flip limiter B04.2 or the second flip limiter B04.3 can abut against the second flip plate limiter axis Z10 of the second side plate YCB. When the second flip plate limiter axis Z10 abuts against the first flip limiter B04.2, the flip lever GG01 can be positioned at the common side power switch-on position. When the second flip plate limiter axis Z10 abuts against the second flip limiter B04.3, the flip lever GG01 can be positioned at the standby side power switch-on position.

[0178] The center axis ZXZ is arranged between the first side plate ZCB and the second side plate YCB, the first section ZXZ.1 of the center axis ZXZ is connected to the first through hole ZCB.1 of the first side plate ZCB, and the second section ZXZ.2 of the center axis ZXZ is connected to the second through hole YCB.1 of the second side plate YCB.

[0179] Based on the above structure, the flip lever GG01 can be switched between the normal power on position, the standby power on position and the double off position. The details are as follows:

[0180] like Fig.15 and Fig.25 a to Fig.25 As shown in FIG. 3 , when the transfer switch is in the state of closing the power supply on the common side, the flip lever GG01 is limited by the first flip limit axis Z03 and is in the maximum angle position of its counterclockwise rotation. Since the first flip spring TH01 and the second flip spring TH01' are in a compressed state, the first flip spring TH01 and the second flip spring TH01' have a tendency to push the first flip plate B02 to rotate clockwise. The first flip plate B02 also has a tendency to rotate clockwise by linking the second flip plate B04 through the central axis ZXZ. At this time, the first flip limit portion B04.2 of the second flip plate B04 abuts against the second flip plate limit axis Z10 to limit the second flip plate B04.

[0181] like Fig.26As shown, the center axis ZXZ rotates counterclockwise, and the center axis ZXZ will drive the first flip plate B02 and the second flip plate B04 to rotate. During the rotation of the first flip plate B02, it gradually compresses the first flip spring TH01 and the second flip spring TH01', so that the first flip spring TH01 and the second flip spring TH01' continuously store energy. When the first flip spring mounting part GG01.2, the first flip spring fixing part B02.2, the second flip spring fixing part B02.3 and the second flip spring mounting part GG01.3 are located in the same straight line and coincide with the center line of the flip lever GG01, the first flip spring TH01 and the second flip spring TH01' are in the state of maximum compression, and the flip lever GG01 is in the dead point position of maintaining a static state.

[0182] like Fig. 27 As shown, the central axis ZXZ continues to rotate counterclockwise, and the first flip plate B02 rotates and the flip lever GG01 passes the dead point. After passing the dead point, the first flip spring TH01 and the second flip spring TH01' will begin to release the compressed spring force, thereby driving the flip lever GG01 to rotate clockwise, and the flip lever GG01 can rotate to the state where the second flip limit axis Z03' abuts, so that the flip lever GG01 is in the state of the backup side power supply closed. Fig.35 a and Fig.35 As shown in b, since the first flip plate B02 and the second flip plate B04 are fixedly mounted on the central axis ZXZ, the central axis ZXZ and the first flip plate B02 will be locked in the corresponding positions because the second flip limiter B04.3 is limited by the second flip plate limiter axis Z10 of the second side plate YCB, and the flip lever GG01 is limited by the second flip limiter axis Z03' to the maximum angle position of its clockwise rotation. Thus, the stability of the structure is achieved by closing the backup side power supply.

[0183] Please continue reading Fig.28 a and Fig.28 b. When the transfer switch is in the standby power supply closing state, the flip lever GG01 is limited by the second flip limit axis Z03' and is in the maximum angle position of its clockwise rotation. Since the first flip spring TH01 and the second flip spring TH01' are in a compressed state, the first flip spring TH01 and the second flip spring TH01' have a tendency to push the first flip plate B02 to rotate counterclockwise. The first flip plate B02 also has a tendency to rotate counterclockwise by linking the second flip plate B04 through the central axis ZXZ. At this time, the first flip limit portion B04.2 of the second flip plate B04 abuts against the second flip plate limit axis Z10 to limit the second flip plate B04.

[0184] like Fig.29As shown, the central axis ZXZ rotates clockwise, and the central axis ZXZ will drive the first flip plate B02 and the second flip plate B04 to rotate. During the rotation of the first flip plate B02, it gradually compresses the first flip spring TH01 and the second flip spring TH01', so that the first flip spring TH01 and the second flip spring TH01' continuously store energy. When the first flip spring mounting part GG01.2, the first flip spring fixing part B02.2, the second flip spring fixing part B02.3 and the second flip spring mounting part GG01.3 are located in the same straight line and coincide with the center line of the flip lever GG01, the first flip spring TH01 and the second flip spring TH01' are in the state of maximum compression, and the flip lever GG01 is in the dead point position of maintaining a static state.

[0185] like Fig.25 a to Fig.25 c, the central axis ZXZ continues to rotate clockwise, and the first flip plate B02 rotates and the flip lever GG01 passes the dead point. After passing the dead point, the first flip spring TH01 and the second flip spring TH01' will begin to release the compressed spring force, thereby driving the flip lever GG01 to rotate counterclockwise, and the flip lever GG01 can rotate to the state where the first flip limit axis Z03 abuts, so that the flip lever GG01 is in the state of closing the power supply on the common side.

[0186] From the above process, it can be known that the flip lever GG01 can be driven to rotate by the rotation of the central axis ZXZ, so that the flip lever GG01 can be switched between the normal side power on position and the standby side power on position. In conjunction with the aforementioned locking or unlocking of the flip lever GG01 in the double open position, the position switching and position locking of the flip lever GG01 between the normal side power on position, the double open position and the standby side power on position can be achieved.
