[0087] Figure 5 2 is a schematic structural diagram of the front side of the second side plate YCB (i.e., the side of the second side plate YCB facing away from the first side plate ZCB) in the embodiment of the present application. Figure 4 and Figure 5 As shown, the back side of the first side plate ZCB (i.e., the side of the first side plate ZCB facing the second side plate YCB) is fixedly provided with a first flip limit axis Z03 and a second flip limit axis Z03', etc., and a through hole is provided at a corresponding position on the second side plate YCB. The first side plate ZCB and the second side plate YCB are fixed together back to back by the aforementioned axis and through hole.

[0088] Figure 6 : is a schematic diagram of the structure of the central axis ZXZ in the embodiment of the present application. The central axis ZXZ is a stepped axis, which includes the first section ZXZ.1, the fifth section ZXZ.5, the fourth section ZXZ.4, the second section ZXZ.2, and the third section ZXZ.3 in the axial direction. The cross-sectional dimensions between two adjacent sections change to form a shaft shoulder. Figure 3-Figure 5 As shown, the first side plate ZCB is provided with a first through hole ZCB.1, and the second side plate YCB is provided with a second through hole YCB.1. The central axis ZXZ is located between the first side plate ZCB and the second side plate YCB. Specifically, the first section ZXZ.1 of the central axis ZXZ passes through the first through hole ZCB.1, and the second section ZXZ.2 passes through the second through hole YCB.1.

[0089] like Figure 7 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 flip lever GG01 is provided with a flip lever protrusion Z12 on the surface facing the second side plate YCB, and accordingly, as shown Figure 5 As 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.

[0090] Please refer to Figure 8, from the perspective of the back side of the first side plate ZCB, the flip lever GG01 is located between the first flip limit axis Z03 and the second flip limit axis Z03' in the circumferential direction. Optionally, the number of the first flip limit axis Z03 is two, and they are symmetrically arranged along the central axis ZXZ. The number of the second flip limit axis Z03' is two, and they are symmetrically arranged along the central axis ZXZ. Figure 8 From the perspective of , the flip lever GG01 is at the maximum position of counterclockwise rotation (i.e., the first rotation position), and the two arms of the flip lever GG01 respectively abut against the two first flip limit axes Z03. When the flip lever GG01 is at the maximum position of clockwise rotation (i.e., the third rotation position), the two arms of the flip lever GG01 respectively abut against the two second flip limit axes Z03'. The flip lever GG01 also has a second rotation position located between the first rotation position and the third rotation position.

[0091] [Gear transmission]

[0092] Fig. 9 It 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 Figure 7 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.

[0093] Fig.10 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 5As shown, a second gear mounting shaft Z09 is provided on the second side plate YCB. The second gear mounting part 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 the second tooth CL2.2 meshing with the first tooth CL1.3. The second gear linkage part 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 first static contact at the common side power supply end, and a second static contact at the standby side power supply end. The second gear CL2 controls the moving contact to contact with the first static contact at the common side power supply end, contact with the second static contact at the standby side power supply end, and separate from both static contacts, thereby realizing the common side power supply closing state, the standby side power supply closing state, and the double-split state respectively.

[0094] like Fig.11 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.11 The 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 first static contact of the common side power supply terminal, and the common side power supply is closed.

[0095] like Fig.12 As shown, when the switch is in the double split state, flip lever GG01 ( Fig.12 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.

[0096] like Fig.13 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.13 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 CL2.3, and the moving contact contacts the second static contact of the backup side power supply terminal, and the backup side power supply is closed.

[0097] 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, which can reduce the force on each part of the conversion switch during the three-state conversion process, thereby improving the product life.

[0098] [Switch position display]

[0099] Fig.14 It is a schematic diagram of the structure of the indicator ZSJ01 in the embodiment of the present application. The indicator ZSJ01 includes an indicator mounting portion ZSJ01.1, an indicator trigger portion ZSJ01.2, an indicator portion ZSJ01.3, an indicator reset portion ZSJ01.4, and an indicator limit portion ZSJ01.5.

The indicator portion ZSJ01.3 is located at the end of the side where the indicator mounting portion ZSJ01.1 is located. The indicator limit portion ZSJ01.5 is located at the corner of the L-shape. The indicator trigger portion ZSJ01.2 is located at the end of the other side of the L-shape. The indicator ZSJ01 is resettable and rotatable on the first side plate ZCB. Specifically, as Figure 4 As shown, the back of the first side plate ZCB is provided with an indicator mounting shaft Z28 and a ninth spring mounting shaft Z06d. The indicator mounting portion ZSJ01.1 is sleeved on the indicator mounting shaft Z28, so that the indicator ZSJ01 can rotate around the indicator mounting shaft Z28. One end of the ninth spring TH06 is fixed on the ninth spring mounting shaft Z06d, and the other end is fixed on the indicator reset portion ZSJ01.4, so that the indicator ZSJ01 has a tendency to reset after rotation. Fig.15 As shown, the indicator part ZSJ01.3 protrudes from the first side panel ZCB to provide a better display effect. The indicator part ZSJ01.3 has an outer surface, and the projection of the outer surface in the rotation plane of the indicator ZSJ01 extends circumferentially. Specifically, the projection can be completely extended circumferentially, that is, the outer surface is an arc-shaped surface; the projection can also have a component extending in the circumferential direction, in which case the outer surface can be the circumscribed surface of a polyhedron, etc. The first indicator mark, the second indicator mark, and the third indicator mark are sequentially arranged along the circumferential direction on the outer surface, so that the indicator mark displayed to the outside is switched with different rotation angles. As an optional embodiment, the first indicator mark, the second indicator mark, and the third indicator mark can be "I", "O", and "II", respectively.

[0100] like Fig.16 As shown, from the perspective of the back of the first side plate, when the transfer switch is in the state of closing the power supply on the common side, the flip lever GG01 is in the first rotation position ( Fig.16 The arm of the flip lever GG01 extending outward from the flip lever mounting hole GG01.1 serves as the flip lever actuating portion GG01.4. The flip lever actuating portion GG01.4 abuts against the indicator actuating portion ZSJ01.2, so that the indicator ZSJ01 rotates counterclockwise to the maximum angle position. At this time, the indicator ZSJ01.3 displays the first indication mark "I" to indicate that the power supply of the common side is closed.

[0101] like Fig.17 As shown, when the conversion switch is in the double split state, the flip lever GG01 is in the second rotation position ( Fig.17 The flip lever actuating part GG01.4 abuts against the indicator actuating part ZSJ01.2, so that the indicator ZSJ01 rotates counterclockwise to the middle position. At this time, the indicator ZSJ01.3 displays the second indicator mark "O" to indicate the double split state.

[0102] like Fig.18 As shown, when the transfer switch is in the standby side power supply closed state, the flip lever GG01 is in the third rotation position ( Fig.18 The flip lever actuating part GG01.4 avoids the indicator actuating part ZSJ01.2, so that the indicator ZSJ01 is reset under the action of the ninth spring TH06. At this time, the indicator limit part ZSJ01.5 abuts against the first flip limit axis Z03, and the indicator ZSJ01 is at its maximum clockwise rotation angle position. The indicator part ZSJ01.3 displays the second indicator mark "II" to indicate that the backup side power supply is closed.
