Under the combined force of the first spring TH04 and the first reset spring CT1.3, the first linkage part LG01.1 moves from the second limit end GG05.2.1b to the first limit end GG05.2.1a. At this time, the angle between the center connecting line AA of the first linkage part LG01.1 and the second linkage part LG01.2 of the connecting rod LG01 and the second groove section GG05.2.2 is greater than 90 degrees and less than 180 degrees. Please refer to Fig.14 , the elastic force Fj acting on the first linkage part LG01.1 is also much greater than the elastic force Ft of the first spring TH04. Fj and Ft are decomposed along the direction of the second slot section GG05.2.2. The component F of Fj downward along the second slot section GG05.2.2 (i.e., toward the third limit end GG05.2.3a of the third slot section GG05.2.3) is much greater than the component F′ of Ft upward along the second slot section GG05.2.2. Therefore, Fig.15 As shown, the first linkage portion LG01.1 will slide downward along the second groove section GG05.2.2 until it contacts the third limit end GG05.2.3a.

[0124] like Fig.16 As shown, in Fig.15 On the basis of , the first electromagnet CT1 is energized, and the first iron core CT1.2 overcomes the thrust of the first return spring CT1.3 and retracts to the left. The first iron core CT1.2 drives the connecting rod LG01 to move, so that the first linkage part LG01.1 moves from the third limit end GG05.2.3a to the fourth limit end GG05.2.3b. Fig.17 As shown, the first electromagnet CT1 remains energized, and the first iron core CT1.2 continues to pull the connecting rod LG01; at the same time, the connecting rod LG01 pulls the first lever GG05 at the fourth limit end GG05.2.3b by the first linkage part LG01.1 abutting against the first pull rod. Fig.17 The first lever GG05 is rotated clockwise to a maximum angle position. At this time, the first lever GG05 is locked at the maximum angle position by other structures.

[0125] like Fig.18 As shown, in Fig.17On the basis of this, the first electromagnet CT1 is de-energized, and the first iron core CT1.2 is pushed out to the right and reset under the action of the first reset spring CT1.3. Under the combined force of the first spring TH04 and the first reset spring CT1.3, the first linkage part LG01.1 moves from the fourth limit end GG05.2.3b to the third limit end GG05.2.3a. At this time, the angle between the center connecting line AA of the first linkage part LG01.1 and the second linkage part LG01.2 of the connecting rod LG01 and the second groove section GG05.2.2 is greater than 90 degrees and less than 180 degrees. Please refer to Fig.19 , the elastic force Fj acting on the first linkage part LG01.1 is also much greater than the elastic force Ft of the first spring TH04. Fj and Ft are decomposed along the direction of the second slot section GG05.2.2. The upward component F of Fj along the second slot section GG05.2.2 (i.e., the direction toward the first limit end GG05.2.1a of the third slot section GG05.2.3) is much greater than the downward component F′ of Ft along the second slot section GG05.2.2. Therefore, Fig.10 As shown, the first linkage portion LG01.1 will slide upward along the second groove section GG05.2.2 until it contacts the first limit end GG05.2.1a.

[0126] Figure 10-Figure 18 The process in the process is repeated and circulated, and the first iron core CT1.2 that completes the unidirectional movement makes the first lever GG05 rotate back and forth clockwise and counterclockwise, thereby driving the central axis ZXZ to rotate back and forth.

[0127] [Energy storage flip structure]

[0128] The energy storage mechanism includes a flip lever GG01, a first flip plate B02, and a flip spring. The flip spring connects the first flip plate B02 and the flip lever GG01. In this embodiment, there are two flip springs, namely, a first flip spring TH01 and a second flip spring TH01′. It can be understood that on the basis of ensuring that the functions of the first flip plate B02 and the flip lever GG01 remain unchanged, the number of flip springs in some optional embodiments can be less or more.

[0129] like Fig. 20As shown, the first flip plate B02 includes a first flip plate mounting portion B02.1 in the middle position. The first flip plate B02 is fixed to the fifth section ZXZ.5 of the central axis ZXZ through the first flip plate mounting portion B02.1, so that the first flip plate B02 can rotate synchronously with the central axis ZXZ. Optionally, the cross section of the fifth section ZXZ.5 of the central axis ZXZ is non-circular, and the first flip plate mounting portion B02.1 is a through hole with the same shape as the cross section of the fifth section ZXZ.5, so that the fifth section ZXZ.5 can pass through the first flip mounting portion and drive the first flip plate B02 to rotate synchronously when rotating. The first flip plate B02 is provided with a first flip spring fixing portion B02.2 and a second flip spring fixing portion B02.3 on opposite sides of the first flip plate mounting portion B02.1.

[0130] like Fig.21 As shown, the flip lever GG01 includes a flip lever mounting hole GG01.1 in the middle position. The flip lever GG01 is installed on the fourth section ZXZ.4 of the central axis ZXZ located between the first side plate ZCB and the second side plate YCB through the flip lever mounting hole GG01.1, so that the flip lever GG01 can rotate around the central axis ZXZ, and the rotation of the flip lever GG01 and the central axis ZXZ is relatively independent. The flip lever GG01 has two arms extending outward from opposite sides of the flip lever mounting hole GG01.1. The ends of the two arms are respectively provided with a first flip spring mounting portion GG01.2 and a second flip spring mounting portion GG01.3. The first flip spring mounting portion GG01.2 corresponds to the first flip spring fixing portion B02.2 of the first flip plate B02, and is respectively used to fix the two ends of the first flip spring TH01. The second flip spring mounting portion GG01.3 corresponds to the second flip spring fixing portion B02.3 of the first flip plate B02, and is used to fix the two ends of the second flip spring TH01'. The flip lever GG01 is provided with a flip lever limiting axis Z13 on the side facing the first side plate ZCB. Figure 3 As shown, the first side plate ZCB is provided with a first notch ZCB.2 to accommodate the flip lever limit axis Z13. When the flip lever GG01 rotates, the flip lever limit axis Z13 passes through the first notch ZCB.2 and moves in the first notch ZCB.2. The flip lever GG01 is provided with a flip lever protrusion Z12 on the side facing the second side plate YCB. Figure 5As shown, a second notch YCB.2 is provided on the second side plate YCB to accommodate the development lever protrusion. When the flip lever GG01 rotates, the flip lever protrusion Z12 passes through the second notch YCB.2 and moves in the second notch YCB.2. Optionally, the number of the flip lever protrusion Z12 and the second notch YCB.2 are both two, the two flip lever protrusions Z12 are symmetrically arranged relative to the flip lever mounting hole GG01.1, and the two second notches YCB.2 are symmetrically arranged relative to the second through hole YCB.1.

[0131] like Fig. 22 As shown, the second flip plate B04 includes a second flip plate mounting portion B04.1 in the middle position. The second flip plate B04 is fixed to the second section ZXZ.2 of the center axis ZXZ by the second flip plate mounting portion B04.1, so that the second flip plate B04 can rotate synchronously with the center axis ZXZ. Optionally, the cross-section of the second section ZXZ.2 of the center axis ZXZ is non-circular, and the second flip plate mounting portion B04.1 is a through hole of the same shape as the cross-section of the second section ZXZ.2, so that the second section ZXZ.2 can pass through the second flip plate mounting portion B04.1 and drive the second flip plate B04 to rotate synchronously when rotating. The second flip plate B04 is provided with a first flip limit portion B04.2 and a second flip limit portion B04.3 along the circumferential direction on the outer side of the second flip plate mounting portion B04.1. The first flip limit portion B04.2 and the second flip limit portion B04.3 are radial protrusions. As shown Figure 5 As shown, a second flip plate limiting axis Z10 is provided on the front of the second side plate YCB. The second flip plate limiting axis Z10 is located between the first flip limiting portion B04.2 and the second flip limiting portion B04.3 in the circumferential direction. When the second flip plate B04 rotates with the central axis ZXZ, the second flip plate limiting axis Z10 limits the maximum counterclockwise and clockwise rotation positions of the second flip plate B04 and the central axis ZXZ by abutting against the first flip limiting portion B04.2 and the second flip limiting portion B04.3. Optionally, the number of the second flip plate limiting axis Z10 is two and they are symmetrically arranged relative to the second through hole YCB.1; the number of the first flip limiting portion B04.2 and the second flip limiting portion B04.3 are also two respectively, the two first flip limiting portions B04.2 are symmetrically arranged relative to the second flip plate mounting portion B04.1, and the two second flip limiting portions B04.3 are symmetrically arranged relative to the second flip plate mounting portion B04.1.

[0132] Please refer to Fig.23 , from the perspective of the back side of the second side plate YCB, the flip lever GG01 is located between the first flip limit axis Z03 and the second flip limit axis Z03' in the circumferential direction. Fig.23The switching switch in (a) is in the state of closing the power supply on the common side. Since there is an angle between the line connecting the first flip spring fixing part B02.2 and the second flip spring fixing part B02.3 and the line connecting the first flip spring mounting part GG01.2 and the second flip spring mounting part GG01.3, and 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′ both exert elastic force on the first flip plate B02 and the flip lever GG01, and this elastic force makes the first flip plate B02 and the flip lever GG01 tend to rotate in the opposite clockwise direction. Fig.23 From the perspective of (a), the flip lever GG01 is against the first flip limit axis Z03 on the back of the second side plate YCB under the action of elastic force, and the flip lever GG01 is in the maximum position of counterclockwise rotation, that is, the first rotation position. At the same time, the first flip plate B02 has a tendency to rotate clockwise, such as Fig.23 As shown in (b), the first flip plate B02 is connected to the second flip plate B04 through the central axis ZXZ, so that the second flip plate B04 also has a tendency to rotate clockwise, and the first flip limit portion B04.2 of the second flip plate B04 abuts against the second flip plate limit axis Z10 on the front side of the second side plate YCB, and the first flip plate B02 and the second flip plate B04 are at the maximum position of clockwise rotation (with Fig.23 From the perspective of the front of the second side plate YCB in (c), the first flip plate B02 and the second flip plate B04 are in the maximum position of counterclockwise rotation), that is, the first flip plate B02 and the second flip plate B04 are in the first flip position and the third flip position, respectively.

[0133] exist Fig.23 (a), if the first lever GG05 and the central axis ZXZ are linked to rotate counterclockwise (such as Figure 10-12 The first flip plate B02 and the second flip plate B04 also rotate counterclockwise at the same time. During the rotation of the first flip plate B02, the first flip plate B02 gradually compresses the first flip spring TH01 and the second flip spring TH01′, and the first flip spring TH01 and the second flip spring TH01′ begin to store energy. Fig.24As shown, when the line B-Bn connecting the contact point between the first flip plate B02 and the first flip spring TH01 (i.e., the first flip spring fixing part B02.2) and the contact point between the first flip spring TH01 and the flip lever GG01 (i.e., the first flip spring mounting part GG01.2) coincides with the center line CC of the flip lever GG01, the first flip spring TH01 is compressed to the maximum position, and at the same time, the line B'-B'n connecting the contact point between the first flip plate B02 and the second flip spring TH01' (i.e., the second flip spring fixing part B02.3) and the contact point between the second flip spring TH01' and the flip lever GG01 (i.e., the second flip spring mounting part GG01.3) coincides with the center line CC of the flip lever GG01, and the second flip spring TH01' is compressed to the maximum position. At this time, the first flip spring TH01 and the second flip spring TH01' will not apply a rotational force to the first flip plate B02 and the flip lever GG01, and the energy storage mechanism is in a dead point position.

[0134] like Fig.25 As shown, in Fig.24 On the basis of the counterclockwise rotation of the central axis ZXZ, the first flip spring TH01 and the second flip spring TH01′ rotate past the dead point and begin to release the stored energy, prompting the flip lever GG01 to rotate clockwise, thereby disconnecting the power supply on the common side. It can be understood that the first flip spring TH01 and the second flip spring TH01′ also make the first flip plate B02 have a tendency to rotate counterclockwise. Fig.26 As shown, the central axis ZXZ continues to rotate counterclockwise until the second flip limit portion B04.3 of the second flip plate B04 abuts against the second flip plate limit axis Z10, and the first flip plate B02 and the second flip plate B04 are at the maximum position of counterclockwise rotation (if Fig.26 (b) From the perspective of the front of the second side plate YCB, the second flip plate B04 is at the maximum position of clockwise rotation), that is, the first flip plate B02 and the second flip plate B04 are respectively at the second flip position and the fourth flip position; if the flip lever GG01 continues to rotate clockwise until it abuts against the second flip limit axis Z03', the backup side power supply is closed. At this time, the flip lever GG01 is at the maximum position of clockwise rotation, that is, at the second rotation position.

[0135] exist Fig.26 On the basis that the switching switch of the backup side power supply is closed, if the first lever GG05 and the central axis ZXZ are linked to rotate clockwise (such as Figure 15-17The first flip plate B02 and the second flip plate B04 also rotate clockwise at the same time. During the rotation of the first flip plate B02, the first flip plate B02 gradually compresses the first flip spring TH01 and the second flip spring TH01′, and the first flip spring TH01 and the second flip spring TH01′ begin to store energy. Fig. 27 As shown, when the line B-Bn connecting the contact point between the first flip plate B02 and the first flip spring TH01 (i.e., the first flip spring fixing part B02.2) and the contact point between the first flip spring TH01 and the flip lever GG01 (i.e., the first flip spring mounting part GG01.2) coincides with the center line CC of the flip lever GG01, the first flip spring TH01 is compressed to the maximum position, and at the same time, the line B'-B'n connecting the contact point between the first flip plate B02 and the second flip spring TH01' (i.e., the second flip spring fixing part B02.3) and the contact point between the second flip spring TH01' and the flip lever GG01 (i.e., the second flip spring mounting part GG01.3) coincides with the center line CC of the flip lever GG01, and the second flip spring TH01' is compressed to the maximum position. At this time, the first flip spring TH01 and the second flip spring TH01' will not apply a rotational force to the first flip plate B02 and the flip lever GG01, and the energy storage mechanism is in a dead point position.

[0136] exist Fig. 27 On the basis of the central axis ZXZ continues to rotate clockwise, the first flip spring TH01 and the second flip spring TH01′ rotate past the dead point and begin to release the stored energy, prompting the flip lever GG01 to rotate counterclockwise, thereby disconnecting the backup side power supply. It can be understood that the first flip spring TH01 and the second flip spring TH01′ also make the first flip plate B02 have a tendency to rotate clockwise. Fig.23 As shown, the central axis ZXZ continues to rotate clockwise until the first flip limit portion B04.2 of the second flip plate B04 abuts against the second flip plate limit axis Z10, and the first flip plate B02 and the second flip plate B04 are at the maximum position of clockwise rotation (if Fig.23 (b) From the perspective of the front of the second side plate YCB, the second flip plate B04 is at the maximum position of counterclockwise rotation), that is, the first flip plate B02 and the second flip plate B04 are at the first flip position and the third flip position respectively; if the flip lever GG01 continues to rotate counterclockwise until it abuts against the first flip limit axis Z03, the power supply on the common side is closed. At this time, the flip lever GG01 is at the maximum position of counterclockwise rotation, that is, at the first rotation position.

[0137] In this embodiment, the reciprocating rotation of the flip lever GG01 between the first rotation position and the third rotation position is achieved by the reciprocating rotation of the first flip plate B02 between the first flip position and the second flip position and the reciprocating rotation of the second flip plate B04 between the third flip position and the fourth flip position.

[0138] [Locking and unlocking of the dual position]

[0139] Fig.28 It is a schematic diagram of the structure of the second electromagnet CT2 in the embodiment of the present application. The second electromagnet CT2 includes a second yoke CT2.1, a second iron core CT2.2, and a second return spring CT2.3. The second electromagnet CT2 is fixed to the first side plate ZCB through the second yoke CT2.1. The second iron core CT2.2 is connected to the second return spring CT2.3, the second return spring CT2.3 is located inside the second yoke CT2.1, and the second iron core CT2.2 partially penetrates the second yoke CT2.1. When the second electromagnet CT2 is powered off, the second iron core CT2.2 retracts relatively under the elastic force of the second return spring CT2.3. When the second electromagnet CT2 is powered on, the second iron core CT2.2 overcomes the elastic force of the second return spring CT2.3 under the action of magnetic force, thereby being relatively ejected. It can be understood that in other optional embodiments, the second electromagnet CT2 can be replaced by a second drive mechanism, and the second drive mechanism can be other mechanisms that realize the function of linear reciprocating movement, such as an electric telescopic rod.

[0140] Fig.29 It is a structural schematic diagram of the first bracket ZJ01 in the embodiment of the present application. The first bracket ZJ01 includes a side panel mounting portion ZJ01.1, a first bracket mounting portion ZJ01.2, a fourth notch ZJ01.3, and a second lever mounting axis Z22. The first bracket ZJ01 is mounted on the first bracket mounting axis Z04 of the first side panel ZCB through the side panel mounting portion ZJ01.1. Specifically, the side panel mounting portion ZJ01.1 may have a plurality of through holes, and the number of the first bracket mounting axis Z04 corresponds to the number of through holes of the side panel mounting portion ZJ01.1. The second lever mounting axis Z22 is located on the side of the first bracket ZJ01 facing the first side panel ZCB.

[0141] Fig.30It is a schematic diagram of the structure of the second bracket ZJ02 in the embodiment of the present application. The second bracket ZJ02 includes a second bracket mounting portion ZJ02.2, a bracket linkage portion ZJ02.1, a bracket reset portion ZJ02.3, and a bracket limit axis Z23. The second bracket ZJ02 is rotatably mounted on the first bracket mounting portion ZJ01.2 of the first bracket ZJ01 through the second bracket mounting portion ZJ02.2. Specifically, the second bracket mounting portion ZJ02.2 and the first bracket mounting portion ZJ01.2 are both through holes, and the two are aligned and passed through by the rotating shaft. The bracket linkage portion ZJ02.1 is aligned with the second iron core CT2.2 of the second electromagnet CT2, and after the second iron core CT2.2 is ejected, the second bracket ZJ02 rotates around the rotating axis relative to the first bracket ZJ01. Figure 1 and Figure 3 As shown, a second spring mounting shaft Z06a is provided on the first side plate ZCB. One end of the second spring TH03a is fixed on the second spring mounting shaft Z06a, and the other end is fixed on the bracket reset portion ZJ02.3, so that the second bracket ZJ02 has a tendency to reset and rotate to the initial position after rotation. The bracket limit shaft Z23 is located in the fourth notch ZJ01.3 of the first bracket ZJ01. During the rotation of the second bracket ZJ02, the bracket limit shaft Z23 moves in the fourth notch ZJ01.3, so that the fourth notch ZJ01.3 limits the rotation range of the second bracket ZJ02.

[0142] Fig.31 : is a schematic diagram of the structure of the second lever GG07 in the embodiment of the present application. The second lever GG07 includes a second lever mounting portion GG07.5, a first stop portion GG07.1, a second stop portion GG07.2, a third stop portion GG07.3, and a fourth stop portion GG07.4. The second lever GG07 can be mounted on the second lever mounting axis Z22 of the first bracket ZJ01 through the second lever mounting portion GG07.5, so that the second lever GG07 can rotate relative to the second lever mounting axis Z22 between the first bracket ZJ01 and the first side plate ZCB. In some optional embodiments, the second lever mounting axis Z22 can also be located on the first side plate ZCB. The second lever GG07 extends outward from the second lever mounting portion GG07.5 to form three arms, which are Y-shaped as a whole. Two of the arms have a first stop portion GG07.1 and a second stop portion GG07.2, respectively. The tipping lever limit axis Z13 passes through the first notch ZCB.2 and is located between the first stop GG07.1 and the second stop GG07.2. The other arm is provided with a third stop GG07.3 and a fourth stop GG07.4 on both sides.

[0143] like Fig.32 As shown in (a), when the transfer switch is in the state of closing the power supply on the common side, the flip lever GG01 is moved by the first flip limit axis Z03 ( Fig.32The second lever GG07 is at its maximum clockwise rotation angle, and the fourth stopper GG07.4 is located on the left side of the bracket limit axis Z23 (with the bracket limit axis Z23 being the left side). Fig.32 (b) The second lever GG07 is at the maximum angular position of counterclockwise rotation, and the fourth stopper GG07.4 is located on the right side of the bracket limit axis Z23). The second electromagnet CT2 is powered off, and the second iron core CT2.2 is retracted under the action of the second reset spring CT2.3 and does not contact the bracket linkage part ZJ02.1. The second bracket ZJ02 is reset to its maximum angular position of counterclockwise rotation under the action of the second spring TH03a.

[0144] like Fig.33 (a) and Fig.33 As shown in (b), Fig.32 (a) The transfer switch is opened on the common side, the central axis ZXZ rotates counterclockwise, and the flip lever GG01 rotates clockwise. The flip lever limit axis Z13 is separated from the contact with the second stopper GG07.2 of the second lever GG07 and moves leftward in the first notch ZCB.2 (to Fig.33 (c) shows that the flip lever limit axis Z13 moves to the right, and then gradually moves to contact the first stop GG07.1. At this time, the energy storage mechanism has passed the dead point position, and the flip lever GG01 still has a tendency to continue to rotate clockwise. Fig.33 (c) shows that the flip lever limit axis Z13 makes the second lever GG07 tend to rotate clockwise. Since the second bracket ZJ02 is reset at this time, the bracket limit axis Z23 is in the limit position, and the second lever GG07 is limited by the contact between the fourth stopper GG07.4 and the bracket limit axis Z23, and cannot rotate clockwise, so the flip lever GG01 is also limited. Fig.33 As shown in (c), at this time, the flip lever GG01 is limited to the middle position between the two maximum angle positions of counterclockwise and clockwise rotation. The transfer switch is in a state where both the common side and the standby side are opened at the same time, that is, the double-open state.

[0145] like Fig.34 As shown in (a), Fig.33The second electromagnet CT2 is energized on the basis of the second magnetic field. The second iron core CT2.2 is pushed out to the right, contacts the bracket linkage part ZJ02.1 of the second bracket ZJ02 and makes the second bracket ZJ02 rotate clockwise to overcome the elastic force of the second spring TH03a. During the rotation of the second bracket ZJ02, the bracket limit axis Z23 moves downward from the limit position to the avoidance position and disengages from the fourth stop part GG07.4 of the second lever GG07, and the second lever GG07 is released from the limit position. Fig.35 As shown in (a), after the second lever GG07 is released from the limit, the flip lever limit axis Z13 of the flip lever GG01 continues to rotate clockwise to the maximum angle position, and the backup side power supply of the switch is closed. In this process, the flip lever limit axis Z13 contacts the first stopper GG07.1 and drives the second lever GG07 to rotate counterclockwise, so that the second lever GG07 rotates counterclockwise to the maximum angle position. At this time, the second electromagnet CT2 is powered off, as shown in FIG. Fig.35 As shown in (a), the second core CT2.2 retracts to the left, and the second bracket ZJ02 rotates counterclockwise to the maximum angle position under the action of the second spring TH03a. Fig.35 As shown in (b), the bracket limit axis Z23 moves upward from the avoidance position to the limit position, and the third stopper GG07.3 of the second lever GG07 is located on the left side of the bracket limit axis Z23.

[0146] Figure 32-Figure 35 That is, it shows the conversion process of the transfer switch from the common side power supply closing - double opening - standby side power supply closing. It can be understood that if the transfer switch needs to be changed from Fig.33 The double-open state is switched to the common side power supply closing (such as Fig.32 ), it is only necessary to control the first electromagnet CT1 to be energized.

[0147] Fig.35 In (a), the transfer switch is in the standby side power supply closed state. At this time, if the transfer switch is opened on the standby side, the center axis ZXZ rotates clockwise and the flip lever GG01 rotates counterclockwise. Fig.36 As shown in (a), the tipping lever limit axis Z13 is out of contact with the first stopper GG07.1 of the second lever GG07 and moves rightward in the first notch ZCB.2 (to Fig.36 (c) shows that the flip lever limit axis Z13 moves to the left, and then gradually moves to contact the second stopper GG07.2. At this time, the energy storage mechanism has passed the dead point position, and the flip lever GG01 still has a tendency to continue to rotate counterclockwise. Fig.36(c) shows that the flip lever limit axis Z13 makes the second lever GG07 tend to rotate counterclockwise. Since the second bracket ZJ02 is reset at this time, the bracket limit axis Z23 is in the limit position, and the second lever GG07 is limited by the contact between the third stopper GG07.3 and the bracket limit axis Z23, and cannot rotate counterclockwise, so the flip lever GG01 is also limited. Fig.36 As shown in (b), at this time, the flip lever GG01 is limited to the middle position between the two maximum angle positions of counterclockwise and clockwise rotation. The transfer switch is in a state where both the common side and the standby side are opened at the same time, that is, the double-open state.

[0148] like Fig.37 As shown in (a), Fig.36 The second electromagnet CT2 is energized on the basis of . The second iron core CT2.2 is pushed out to the right, contacts the bracket linkage part ZJ02.1 of the second bracket ZJ02 and makes the second bracket ZJ02 rotate clockwise to overcome the elastic force of the second spring TH03a. During the rotation of the second bracket ZJ02, the bracket limit axis Z23 moves downward from the limit position to the avoidance position and disengages from the third stop part GG07.3 of the second lever GG07, and the second lever GG07 is released from the limit position. Fig.32 As shown in (a), after the second lever GG07 is released from the limit, the flip lever GG01 continues to rotate counterclockwise to the maximum angle position, and the power supply on the common side of the conversion switch is closed. In this process, the flip lever limit shaft Z13 contacts the second stopper GG07.2 and drives the second lever GG07 to rotate clockwise, so that the second lever GG07 rotates clockwise to the maximum angle position. At this time, the second electromagnet CT2 is powered off, the second iron core CT2.2 retracts to the left, and the second bracket ZJ02 is reset and rotated counterclockwise to the maximum angle position under the action of the second spring TH03a. Fig.32 As shown in (b), the bracket limit axis Z23 moves upward from the avoidance position to the limit position, and the fourth stopper GG07.4 of the second lever GG07 is located on the right side of the bracket limit axis Z23.

[0149] Figure 35-Figure 37 Then Fig.32 , showing the conversion process of the transfer switch from the backup side power supply closing - double breaking - normal side power supply closing. It can be understood that if the transfer switch needs to be Fig.36 The double-open state is switched to the standby side power supply closing (such as Fig.35 ), it is only necessary to control the first electromagnet CT1 to be energized.

[0150] [Gear transmission]

[0151] Fig.38It is a schematic diagram of the structure of the first gear CL1 in the embodiment of the present application. The first gear CL1 includes a first gear mounting portion CL1.1, a first gear linkage portion CL1.2, and a first tooth CL1.3. The first gear CL1 is mounted on the third section ZXZ.3 of the center axis ZXZ through the first gear mounting portion CL1.1, so that the first gear CL1 can rotate around the center axis ZXZ, and the rotation of the first gear CL1 and the center axis ZXZ is relatively independent. The first gear linkage portion CL1.2 has a plurality of through holes. Optionally, the number of through holes is two and they are respectively located on both sides of the first gear mounting portion CL1.1. Accordingly, as Fig. 20 As shown, the flip lever protrusion Z12 has the same number of shafts as the through holes of the first gear linkage part CL1.2, as shown in FIG. Figure 5 As shown, the number of the second notches YCB.2 on the second side plate YCB is the same as the number of through holes of the first gear linkage part CL1.2. The first gear linkage part CL1.2 is fixed to the end of the flip lever protrusion Z12 passing through the second notch YCB.2, so that the first gear CL1 is located on the front of the second side plate YCB and can rotate synchronously with the flip lever GG01.

[0152] Fig.39 2 is a schematic diagram of the structure of the second gear CL2 in the embodiment of the present application. The second gear CL2 includes a second gear mounting portion CL2.1, a second tooth CL2.2, and a second gear linkage portion CL2.3. Figure 5 As shown, a second gear mounting shaft Z09 is provided on the second side plate YCB. The second gear mounting portion CL2.1 cooperates with the second gear mounting shaft Z09 so that the second gear CL2 is mounted on the second side plate YCB and can rotate around the second gear mounting shaft Z09. The second gear CL2 realizes linkage with the first gear CL1 by meshing the second tooth CL2.2 with the first tooth CL1.3. The second gear linkage portion CL2.3 links the contact system of the conversion switch through the transmission component to realize the connection and disconnection of the contact system. Optionally, the contact system includes a moving contact, a static contact at the common side power supply end, and a static contact at the standby side power supply end. The second gear CL2 controls the moving contact to contact with the static contact at the common side power supply end, contact with the static contact at the standby side power supply end, and separate from both static contacts by rotating, thereby realizing the common side power supply closing state, the standby side power supply closing state, and the double-split state respectively.

[0153] like Fig.40 As shown, when the transfer switch is in the state of closing the power supply on the common side, from the front view of the second side plate YCB, flip the lever GG01 ( Fig.40The first gear CL1 is in the maximum angular position of its clockwise rotation (not shown). Accordingly, the flip lever GG01 links the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is also in the maximum angular position of its clockwise rotation. The first gear CL1 pulls the second gear CL2 through the first tooth CL1.3, so that the second gear CL2 is in the maximum angular position of its counterclockwise rotation and is fixed. The second gear CL2 activates the contact system of the transfer switch through the second gear linkage part CL2.3, and the moving contact contacts the static contact of the common side power supply end, and the common side power supply is closed.

[0154] like Fig.41 As shown, when the switch is in the double split state, flip lever GG01 ( Fig.41 The first gear CL1 is in the middle position between the two maximum angle positions of counterclockwise and clockwise rotation (not shown). Accordingly, the flip lever GG01 links the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is also in the middle position between the two maximum angle positions of counterclockwise and clockwise rotation. The first gear CL1 pulls the second gear CL2 through the first tooth CL1.3, so that the second gear CL2 is located in the middle position between the two maximum angle positions of counterclockwise and clockwise rotation and is fixed. The second gear CL2 activates the contact system of the transfer switch through the second gear linkage part CL2.3, and the moving contact is separated from the two static contacts to achieve the double-split state.

[0155] like Fig.42 As shown, when the transfer switch is in the standby side power supply closed state, from the front view of the second side plate YCB, flip lever GG01 ( Fig.42 The first gear CL1 is in the maximum angular position of its counterclockwise rotation (not shown). Accordingly, the flip lever GG01 links the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is also in the maximum angular position of its counterclockwise rotation. The first gear CL1 pulls the second gear CL2 through the first tooth CL1.3, so that the second gear CL2 is in the maximum angular position of its clockwise rotation and is fixed. The second gear CL2 activates the contact system of the transfer switch through the second gear linkage part CL2.3, and the moving contact contacts the static contact of the backup side power supply end, and the backup side power supply is closed.

[0156] In this embodiment, after the rotation angle of the flip lever GG01 is amplified by the first gear CL1 and the second gear CL2, the closing and opening angles of the contact system of the conversion switch are finally obtained to be larger, which is beneficial to improve the safety during the power switching process. At the same time, the pitch circle radius of the first gear CL1 is larger than the pitch circle radius of the second gear CL2. When the conversion switch is in the switching state, the rotation speed of the second gear CL2 is higher than the rotation speed of the first gear CL1, which can improve the speed of the switching state. In addition, when the torque applied to the contact system by the second gear CL2 is constant, since the pitch circle radius of the first gear CL1 is larger, the torque output by the flip lever GG01 is smaller, and the force value requirement of the flip spring (the first flip spring TH01 and the second flip spring TH01′) is smaller, which can reduce the force on each part of the conversion switch during the three-state conversion process, thereby improving the product life.

[0157] [Switch position signal acquisition]

[0158] like Fig. 22 As shown, the second flip plate B04 also includes a first flip linkage portion B04.4 protruding outward.

[0159] Fig.43 : is a schematic diagram of the structure of the sixth lever GG08 in the embodiment of the present application. The sixth lever GG08 is arranged on the front of the second side surface so as to be resettable and rotatable. Specifically, the sixth lever GG08 includes a sixth lever mounting portion GG08.1, a fifth notch GG08.3, a sixth lever reset portion GG08.4, a sixth lever linkage portion GG08.5, and a sixth lever actuating portion GG08.6. Figure 5 As shown, the second side plate YCB is provided with a sixth lever mounting axis Z01a, a sixth lever limiting axis Z01a′, and a seventh spring mounting axis Z02a. The sixth lever mounting portion GG08.1 is sleeved on the sixth lever mounting axis Z01a, so that the sixth lever GG08 can rotate around the sixth lever mounting axis Z01a. The sixth lever limiting axis Z01a′ on the second side plate YCB is located in the fifth notch GG08.3 of the sixth lever GG08, so that the sixth lever GG08 can be limited in rotation range by the sixth lever limiting axis Z01a′ during the rotation process. One end of the seventh spring TH05 is fixed on the seventh spring mounting axis Z02a, and the other end is fixed on the sixth lever resetting portion GG08.4, so that the sixth lever GG08 has a tendency to reset and rotate to the initial position after rotation. The sixth lever touch portion GG08.6 is provided at the end of the sixth lever GG08 away from the sixth lever mounting portion GG08.1. The sixth lever linkage portion GG08.5 is located between the sixth lever mounting portion GG08.1 and the sixth lever actuating portion GG08.6.

[0160] Fig.44: is a schematic diagram of the structure of the signal unit in the embodiment of the present application. The signal unit includes a third bracket ZJ03, a first output element WDKG01, a second output element WDKG02, and a third output element WDKG03. Figure 5 As shown, a third bracket mounting shaft Z27 is provided on the front side of the second side plate YCB. The third bracket ZJ03 is fixed to the second side plate YCB through the third bracket mounting shaft Z27. The third bracket ZJ03 has an arc surface, and the center of the arc surface is the rotation center of the first gear CL1, that is, the center of the center axis ZXZ. The first output element WDKG01, the second output element WDKG02, and the third output element WDKG03 are sequentially arranged on the arc surface. The third output element WDKG03 corresponds to the sixth lever touch part GG08.6. The signal unit outputs a corresponding signal according to the triggering condition of each output element. At least one of the first output element WDKG01, the second output element WDKG02, and the third output element WDKG03 includes a cantilever switch, and each output element is triggered when its own cantilever switch is turned on. Optionally, the cantilever switch of the first output element WDKG01 has a first cantilever WDKG01.1, the cantilever switch of the second output element WDKG02 has a second cantilever WDKG02.1, and the cantilever switch of the third output element WDKG03 has a third cantilever WDKG03.1. It can be understood that at least one of the first output element WDKG01, the second output element WDKG02, and the third output element WDKG03 may include a photoelectric switch, etc., and each output element is triggered when its own photoelectric switch detects that light is blocked or reflected.

[0161] like Fig.38 As shown, the first gear CL1 also has a first gear touch portion CL1.4. The first gear touch portion CL1.4 is located in the rotation plane of the first gear CL1 and protrudes axially outward. Optionally, the first gear CL1 is an incomplete gear, and the first tooth CL1.3 area does not completely cover the entire circumference of the first gear CL1. The first tooth CL1.3 area is fan-shaped, and the first gear touch portion CL1.4 and the first tooth CL1.3 are arranged on opposite sides of the first gear mounting portion CL1.1, so that when the first gear CL1 rotates, the first gear touch portion CL1.4 and the first tooth CL1.3 area can both move circumferentially.

[0162] like Fig.45 As shown, when the transfer switch is in the state of closing the power supply on the common side, from the front view of the second side plate YCB, flip the lever GG01 ( Fig.45The first gear CL1 is located at the maximum angular position of its clockwise rotation, and the central axis ZXZ and the second flip plate B04 are located at the maximum angular position of their respective counterclockwise rotation. The flip lever GG01 is linked to the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is located at the maximum angular position of its own clockwise rotation, that is, the first gear CL1 is located at the first position. At this time, the first gear triggering part CL1.4 contacts the second output element WDKG02, and the second output element WDKG02 is triggered by pressing the second cantilever WDKG02.1 of the second output element WDKG02, so that the signal unit outputs the first switch state signal, indicating that the transfer switch is in the common side power supply closed.

[0163] like Fig.46 As shown, when the transfer switch is in the standby side power supply closed state, from the front view of the second side plate YCB, flip lever GG01 ( Fig.46 The first gear CL1 is located at its maximum counterclockwise rotation angle, i.e., the third position. The first gear actuating part CL1.4 contacts the first output element WDKG01, and the first cantilever WDKG01.1 of the first output element WDKG01 is pressed, thereby triggering the first output element WDKG01, so that the signal unit outputs the second switch state signal, indicating that the transfer switch is in the standby side power supply closed state.

[0164] like Fig.47 As shown, when the transfer switch is switched from the common side power on state to the double open state, the bracket limit axis Z23 is in the limit position, and the flip lever GG01 is limited by the bracket limit axis Z23 and the second lever GG07 (see Fig.33 ), the flip lever GG01 is in the middle position between the two maximum angle positions of counterclockwise and clockwise rotation. Correspondingly, the flip lever GG01 links the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is also in the middle position between its two maximum angle positions of counterclockwise and clockwise rotation, that is, the second position. At this time, the first gear triggering part CL1.4 is not in contact with the first output element WDKG01 and the second output element WDKG02, so that the signal unit outputs the third switch state signal, indicating that the conversion switch is in the double split state. At the same time, Fig.47, the second flip plate B04 is at the maximum angular position of clockwise rotation, i.e., the fourth flip position. Although the flip lever GG01 is limited, the flip lever GG01 and the first gear CL1 still have a tendency to rotate counterclockwise, i.e., the first gear CL1 has a tendency to rotate toward the third position. At the same time, the first flip linkage part B04.4 of the second flip plate B04 abuts against the sixth lever linkage part GG08.5 of the sixth lever GG08 and overcomes the elastic force of the seventh spring TH05, thereby rotating the sixth lever GG08. After the sixth lever GG08 rotates to the maximum angular position relative to the initial position, the sixth lever actuating part GG08.6 contacts the third output element WDKG03, and the third output element WDKG03 is triggered by pressing the third cantilever WDKG03.1 of the third output element WDKG03, so that the signal unit outputs the second position signal, indicating that the central axis ZXZ is at its maximum angular position of clockwise rotation. At this time, if the backup side power supply needs to be closed, the second electromagnet CT2 is energized to move the bracket limit axis Z23 to the avoidance position, release the restriction of the first gear CL1 in the second position, and make the first gear CL1 continue to rotate to the third position to complete the backup side power supply closing. If the normal side power supply needs to be closed, the first electromagnet CT1 is energized to rotate the second flip plate B04 counterclockwise to the third flip position, the first flip plate B02 counterclockwise to the first flip position, and the flip lever GG01 drives the first gear CL1 to rotate clockwise to the first position to complete the normal side power supply closing.

[0165] like Fig.48 As shown, when the transfer switch is switched from the standby power supply closing state to the double opening state, the bracket limit axis Z23 is in the limit position, and the flip lever GG01 is limited by the bracket limit axis Z23 and the second lever GG07 (see Fig.36), the flip lever GG01 is in the middle position between the two maximum angle positions of counterclockwise and clockwise rotation. Accordingly, the flip lever GG01 links the first gear CL1 through the flip lever protrusion Z12, so that the first gear CL1 is also in the middle position between its two maximum angle positions of counterclockwise and clockwise rotation, that is, the second position. At this time, the first gear actuating part CL1.4 is not in contact with the first output element WDKG01 and the second output element WDKG02, so that the signal unit outputs the third switch state signal, indicating that the conversion switch is in the double split state. At the same time, the second flip plate B04 is in the maximum angle position of counterclockwise rotation, that is, the third flip position. Although the flip lever GG01 is limited, the flip lever GG01 links the first gear CL1 and still has a tendency to rotate clockwise, that is, the first gear CL1 has a tendency to rotate toward the first position. At the same time, the first flip linkage part B04.4 of the second flip plate B04 is not in contact with the sixth lever linkage part GG08.5 of the sixth lever GG08, so that the sixth lever GG08 is reset. The sixth lever actuating part GG08.6 is also not in contact with the third output element WDKG03, the third output element WDKG03 is not triggered, and the signal unit outputs the first position signal, indicating that the center axis ZXZ is at its maximum angle position of counterclockwise rotation. At this time, if the common side power supply needs to be closed, the second electromagnet CT2 is energized to move the bracket limit axis Z23 to the avoidance position, release the restriction of the first gear CL1 in the second position, so that the first gear CL1 continues to rotate to the first position, and the common side power supply is closed. If the standby side power supply needs to be closed, the first electromagnet CT1 is energized to rotate the second flip plate B04 clockwise to the fourth flip position, the first flip plate B02 is rotated clockwise to the second flip position, and the flip lever GG01 drives the first gear CL1 to rotate counterclockwise to the third position, completing the standby side power supply.

[0166] like Figure 44-Figure 48 As shown, in this embodiment, the signal unit utilizes the triggering of the second output element WDKG02 and the separation of the first output element WDKG01 to output the first switch state signal, indicating that the conversion switch is in the normal side power supply closing state; utilizes the separation of the second output element WDKG02 and the triggering of the first output element WDKG01 to output the second switch state signal, indicating that the conversion switch is in the standby side power supply closing state; utilizes the simultaneous separation of the second output element WDKG02 and the first output element WDKG01 to output the third switch state signal, indicating that the conversion switch is in the double-split state.

[0167] It is understandable that the signal unit and the first gear triggering part CL1.4 may also have a different structure and / or linkage relationship from that in the aforementioned embodiment, so that the signal unit can output a corresponding switch state signal when the first gear triggering part CL1.4 is in different positions.

[0168] Specifically, the signal unit may include at least two output elements. The first gear triggering part CL1.4 triggers at most one output element of the signal unit when it is in any one of the first position, the second position, and the third position. The signal unit outputs signals corresponding to the three switch states in response to the combination of the triggering states of the at least two output elements.

[0169] Optionally, the first output element WDKG01 and the second output element WDKG02 can be set in any two positions selected from the common side closing position, the standby side closing position, and the double open position, and the signal unit outputs signals corresponding to the three switch states according to the combination of the trigger states of the first output element WDKG01 and the second output element WDKG02.

[0170] Optionally, an output element may be provided at the common side closing position, the standby side closing position, and the double opening position. When the output element at a certain position is triggered, the signal unit outputs a signal corresponding to the three switch states at this position.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
