Description

Technical Field

[0001] The present application relates to the technical field of low-voltage transfer switches, and in particular to an electric mechanism of a transfer switch and a transfer switch. Background Art

[0002] The opening and closing of the transfer switch is generally achieved by rotating the moving contact. Sometimes an electric mechanism is set in the transfer switch to drive the moving contact. There are many kinds of electric mechanisms. For example, the electric mechanism includes a motor power component. The chip controls the forward or reverse rotation of the motor. The motor transmits power through gears to drive the moving contact to rotate forward or reverse to achieve closing and opening. Also, the electric mechanism uses two electromagnetic mechanisms as power components, and the two electromagnetic mechanisms respectively push the moving contact to move in two opposite directions to achieve opening and closing, etc. The existing ones either require the motor to work with power for a long time, which consumes a lot of energy and is prone to fatigue, or require two power components to work together, and the overall structure is complex and the control circuit is complex.

[0044] By providing a second lever, a locking mechanism and a second electric component, the flip lever can be limited to a third flip position between the first flip position and the second flip position, so that the moving contact can be in a double-open position between the first closing position and the second closing position.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0073] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0074] On the first aspect, the present application provides an electric mechanism of a switching switch, which realizes the forward and reverse rotation of the moving contact through a power mechanism. The overall structure is simple and the control is simple, which can adapt to the development needs of miniaturization of the switching switch. Moreover, the power mechanism only needs to be energized when driving the moving contact to rotate, and there is no need to work with power on for a long time. It has low energy consumption and is not prone to fatigue.

[0075] like Figure 1 As shown, the electric mechanism of the conversion switch includes a first side plate ZCB, a center axis ZXZ, a first lever GG05, a first electric component and a first connecting rod LG01. The center axis ZXZ is rotatably penetrated through the first side plate ZCB, the first lever GG05 is fixedly arranged on the center axis ZXZ, the first electric component is installed on the first side plate ZCB, the first connecting rod LG01 is connected between the output component of the first electric component and the first lever GG05, and the center axis ZXZ is transmission-connected to the moving contact of the conversion switch, so that the output component of the first electric component drives the first lever GG05 and the center axis ZXZ to rotate forward and reversely through the first connecting rod LG01, so that the moving contact can rotate accordingly to switch the switching state of the conversion switch.

[0076] The first side plate ZCB serves as a base for mounting various components. Figure 2 As shown, the first side plate ZCB is provided with a first through hole ZCB.1, and the central axis ZXZ is rotatably disposed through the first through hole ZCB.1.

[0077] The first lever GG05 is fixedly arranged on the central axis ZXZ. Figure 3 As shown, the first lever GG05 is provided with a first lever mounting portion GG05.1, and the first lever mounting portion GG05.1 is a special-shaped hole, such as Figure 4 As shown, the center axis ZXZ includes a special-shaped first section ZXZ.1, and the first lever mounting portion GG05.1 is sleeved on the first section ZXZ.1 to achieve circumferential fixation of the first lever GG05 and the center axis ZXZ, so that the first lever GG05 and the center axis ZXZ can turn synchronously. The connection method between the first lever GG05 and the center axis ZXZ is not limited to this, and other types of connection methods are also included in the inventive concept of the present application, as long as the synchronous turning of the first lever GG05 and the center axis ZXZ can be achieved, for example, the first lever GG05 and the center axis ZXZ are integrally formed, connected by screws, and so on.

[0078] The first electric component can be installed on the first side plate ZCB, or on the housing of the switching switch or other structures on the switching switch, as long as it can be fixed and enable the output component of the first electric component to move along a set path between the initial position and the actuation position.

[0079] For example, the first side plate ZCB is provided on one side of the first through hole ZCB.1. Figure 2 A notch is formed on the left side of the middle part, and the first electric component is embedded in the notch, so that the first electric component is connected to the first side plate ZCB in at least three directions. At the same time, the first side plate ZCB forms a folded mounting plate ZCB.3 on at least one side of the notch to increase the connection area between the first side plate ZCB and the first electric component and improve the stability of the first electric component.

[0080] The first lever GG05 has a first force-bearing portion and a second force-bearing portion respectively located on both sides of the central axis ZXZ, and the first connecting rod LG01 is swingably connected to the output component to selectively cooperate with the first force-bearing portion and the second force-bearing portion.

[0081] When the output component moves toward the actuating position, the first connecting rod LG01 cooperates with one of the first force-bearing part and the second force-bearing part and applies a force to drive the central axis ZXZ to rotate forward or reversely; when the output component resets toward the initial position, the first connecting rod LG01 is driven to swing to cooperate with the other of the first force-bearing part and the second force-bearing part.

[0082] That is to say, the moving contact provided in the embodiment of the present application has a first closing position and a second closing position, and the electric mechanism has a first closing process of driving the moving contact to move toward the second closing position, and a second closing process of moving toward the first closing position.

[0083] When the moving contact (not shown in the figure) is in the first closing position, Figure 1 As shown, at this time, the first lever GG05 is parked on one side of the central axis ZXZ, the output component is in the initial position, and the first connecting rod LG01 is matched with the first force-bearing part of the first lever GG05. Figure 5 and Figure 6 As shown, if the output component moves from the initial position to the actuating position, a force will be applied to the first force-bearing part with which it is matched at this time through the first connecting rod LG01, thereby driving the first lever GG05 and the center axis ZXZ to rotate forward (counterclockwise in the figure), so that the moving contact switches to the second closing position.

[0084] After the moving contact switches to the second closing position, the output component returns to the initial position. Figure 7 , Figure 8 and Fig. 9 As shown, at this time, the first lever GG05 is parked on the other side of the central axis ZXZ, the first lever GG05 remains stationary, and the first connecting rod LG01 swings to the second force-bearing part, completing the first closing process.

[0085] If the second closing process is required, the moving contact is switched from the second closing position to the first closing position, such as Fig. 9As shown, since the first lever GG05 is parked on the other side of the central axis ZXZ, the output component is in the initial position, and the first connecting rod LG01 is matched with the second force-bearing part of the first lever GG05. Fig.10 and Fig.11 As shown, if the output component moves from the initial position to the actuating position, a force will be applied to the second force-bearing part with which it is matched at this time through the first connecting rod LG01, thereby driving the first lever GG05 and the center axis ZXZ to rotate in the opposite clockwise direction in the figure, so that the moving contact switches to the first closing position.

[0086] After the moving contact is switched to the first closing position, Fig.12 and Fig.13 As shown, the first lever GG05 is docked on one side of the central axis ZXZ again, and the output component returns to the initial position. The first lever GG05 remains stationary, and the first connecting rod LG01 swings to the second force-bearing part and returns to Figure 1 Status shown.

[0087] The setting path of the output component of the first electric component is along a straight line direction, the straight line direction of the setting path is perpendicular to the axial direction of the central axis ZXZ, and the first force-bearing part and the second force-bearing part are located on both sides of the setting path. Therefore, the first connecting rod LG01 swings on both sides of the setting path relative to the output component, and cooperates with the first force-bearing part or the second force-bearing part on both sides of the setting path, so that when the output component moves toward the actuation position along the setting path, it can drive the first lever GG05 and the central axis ZXZ to rotate forward or reversely.

[0088] Optionally, the output component of the first electric component is relatively close to the central axis ZXZ in the initial position, and relatively far from the central axis ZXZ in the actuating position. That is, when the output component moves toward the actuating position, the first lever GG05 is pulled by the first connecting rod LG01; when the output component is reset toward the initial position, the first connecting rod LG01 swings to the other side of the set path to reach the other of the first force-bearing part and the second force-bearing part.

[0089] In some embodiments, in combination Figure 1 and Fig.14As shown, the first electric component is the first electromagnet CT1, and the first electromagnet CT1 includes a first iron core CT1.2, a first magnetic yoke CT1.1 and a first return spring CT1.3. The first magnetic yoke CT1.1 is fixedly arranged on the first side plate ZCB, the first iron core CT1.2 is an output component, the first iron core CT1.2 is movably arranged on the first magnetic yoke CT1.1 along a set path, the first iron core CT1.2 is close to the central axis ZXZ in the initial position and away from the central axis ZXZ in the actuating position, and the first return spring CT1.3 is arranged between the first magnetic yoke CT1.1 and the first iron core CT1.2 to provide the first iron core CT1.2 with an elastic force to return to the initial position.

[0090] In some embodiments, a guide rail is provided on the first lever GG05, and the first force-bearing portion and the second force-bearing portion are located at two ends of the guide rail; Fig.15 As shown, the first connecting rod LG01 includes a first linkage part LG01.1 and a second linkage part LG01.2. The first connecting rod LG01 is swingably connected to the output component through the second linkage part LG01.2. The first linkage part LG01.1 is slidably connected to the guide rail to selectively cooperate with the first force-bearing part and the second force-bearing part.

[0091] In some embodiments, Figure 3 As shown, the guide rail is the second slot section GG05.2.2 formed on the first lever GG05, the first force-bearing part is the first slot section GG05.2.1 formed on the first lever GG05, the second force-bearing part is the third slot section GG05.2.3 formed on the first lever GG05, and the first slot section GG05.2.1 and the third slot section GG05.2.3 are connected at both ends of the second slot section GG05.2.2. That is, the first slot section GG05.2.1, the second slot section GG05.2.2 and the third slot section GG05.2.3 are sequentially connected to form the third slide groove GG05.2, and the first linkage part LG01.1 slides along the third slide groove GG05.2, thereby entering the first slot section GG05.2.1 to pull the first lever GG05 to rotate forward, or entering the third slot section GG05.2.3 to pull the first lever GG05 to rotate reversely. The first linkage part LG01.1 is a roller or a wheel arranged on the first connecting rod LG01. In other embodiments, the guide rail can also be other structures, for example, the guide rail is a slide bar arranged on the first lever GG05, the first force-bearing part and the second force-bearing part are arranged at both ends of the slide bar, and the first linkage part LG01.1 can be a sleeve structure that can slide on the slide bar.

[0092] When the first linkage part LG01.1 cooperates with the first force-bearing part and the output component is reset toward the initial position, Figure 7 and Figure 8As shown, the first linkage part LG01.1 is located at the first force-bearing part, and the angle between the center line of the first linkage part LG01.1 and the second linkage part LG01.2 and the second slot section GG05.2.2 is obtuse. At this time, the center line of the first linkage part LG01.1 and the second linkage part LG01.2 forms an acute angle with the extension line of the second slot section GG05.2.2 toward the first force-bearing part. This makes the force Fj provided by the output part to the first linkage part LG01.1 be decomposed into a component force along the second slot section GG05.2.2 and toward the second force-bearing part when the output part is reset to the initial position, so that the first linkage part LG01.1 moves from the first force-bearing part along the second slot section GG05.2.2 to the second force-bearing part, so that the electric component can act on the second force-bearing part and pull the first lever GG05 to rotate in the opposite direction when it works next time.

[0093] Similarly, when the first linkage part LG01.1 cooperates with the second force-bearing part and the output component is reset toward the initial position, as shown in FIG. Fig.12 and Fig.13 As shown, the first linkage part LG01.1 is located at the second force-bearing part, and the center line of the first linkage part LG01.1 and the second linkage part LG01.2 forms an obtuse angle with the second slot section GG05.2.2. At this time, the center line of the first linkage part LG01.1 and the second linkage part LG01.2 forms an acute angle with the extension line of the second slot section GG05.2.2 toward the second force-bearing part. This makes the force Fj provided by the output component to the first linkage part LG01.1 be decomposed into a component force along the second slot section GG05.2.2 and toward the first force-bearing part when the output component is reset to the initial position, so that the first linkage part LG01.1 moves from the second force-bearing part along the second slot section GG05.2.2 to the first force-bearing part, so that the electric component can act on the first force-bearing part and pull the first lever GG05 to rotate in the positive direction when it works next time.

[0094] In the embodiment of the present application, an obtuse angle is an angle greater than 90° and less than 180°, and an acute angle is an angle greater than 0° and less than 90°.

[0095] Specifically, the first groove section GG05.2.1 includes a first limit end GG05.2.1a and a second limit end GG05.2.1b, the third groove section GG05.2.3 includes a third limit end GG05.2.3a and a fourth limit end GG05.2.3b, the first limit end GG05.2.1a is connected to one end of the second groove section GG05.2.2, and the third limit end GG05.2.3a is connected to the other end of the second groove section GG05.2.2.

[0096] The second groove section GG05.2.2 includes two side walls arranged opposite to each other along its own width direction, the end wall of the first limit end GG05.2.1a and the end wall of the third limit end GG05.2.3a are connected to the two ends of one side wall of the second groove section GG05.2.2, for example, the two ends of the side wall of the second groove section GG05.2.2 relatively far away from the output component, the end wall of the second limit end GG05.2.1b and the end wall of the fourth limit end GG05.2.3b are connected to the two ends of the other side wall of the second groove section GG05.2.2, for example, the two ends of the side wall of the second groove section GG05.2.2 relatively close to the output component.

[0097] When the output component moves toward the actuating position, the first linkage part LG01.1 applies a force to the second limit end GG05.2.1b or the fourth limit end GG05.2.3b, that is, the first linkage part LG01.1 is against the end wall of the second limit end GG05.2.1b or the end wall of the fourth limit end GG05.2.3b to pull the first lever GG05.

[0098] Optionally, the second limit end GG05.2.1b and the fourth limit end GG05.2.3b extend toward the direction where the output component is located, that is, the end wall of the second limit end GG05.2.1b and the end wall of the fourth limit end GG05.2.3b are recessed relative to the side wall of the second groove section GG05.2.2 to form a recess, so that when the output component moves toward the actuating position, it first drives the first linkage part LG01.1 into the recess where the second limit end GG05.2.1b and the fourth limit end GG05.2.3b are located, and then pulls the first lever GG05 to prevent the first linkage part LG01.1 from accidentally sliding along the second groove section GG05.2.2, thereby ensuring that the mechanical structure moves stably and in place.

[0099] Optionally, the angles between the first slot section GG05.2.1 and the third slot section GG05.2.3 and the second slot section GG05.2.2 are acute angles, that is, the second limit end GG05.2.1b extends toward the direction where the output component is located and deviates toward the fourth limit end GG05.2.3b, so that when the output component moves toward the actuating position, if the first linkage part LG01.1 is matched with the first slot section GG05.2.1 at this time, even if the first linkage part LG01.1 has a tendency to slide toward the second slot section GG05.2.2, it can be ensured that the first linkage part LG01.1 can enter the second limit end GG05.2.1b. Similarly, the fourth limit end GG05.2.3b extends toward the direction where the output component is located and is biased toward the second limit end GG05.2.1b, so that when the output component moves toward the actuating position, if the first linkage part LG01.1 is matched with the third groove section GG05.2.3 at this time, even if the first linkage part LG01.1 has a tendency to slide toward the second groove section GG05.2.2, it can be ensured that the first linkage part LG01.1 can enter the fourth limit end GG05.2.3b.

[0100] When the output component is reset toward the initial position, the first linkage part LG01.1 abuts against one of the first limit end GG05.2.1a and the third limit end GG05.2.3a, and slides toward the other of the first limit end GG05.2.1a and the third limit end GG05.2.3a. That is, as mentioned above, when the first linkage part LG01.1 cooperates with the first force-bearing part, and the output component is reset toward the initial position, Figure 7 and Figure 8 As shown, the first linkage part LG01.1 is located at the first force-bearing part, and the angle between the center line of the first linkage part LG01.1 and the second linkage part LG01.2 and the second groove section GG05.2.2 is obtuse. Specifically, the first linkage part LG01.1 is abutted against the first limit end GG05.2.1a, and the center line of the first linkage part LG01.1 and the second linkage part LG01.2 and the line between the first limit end GG05.2.1a and the second limit end GG05.2.1b are obtuse; or, when the first linkage part LG01.1 cooperates with the second force-bearing part and the output component is reset to the initial position, as shown Fig.12 and Fig.13 As shown, the first linkage part LG01.1 is located at the second force-bearing part, and the angle between the center line of the first linkage part LG01.1 and the second linkage part LG01.2 and the second groove section GG05.2.2 forms an obtuse angle. Specifically, the first linkage part LG01.1 is abutted against the second limit end GG05.2.1b, and the center line of the first linkage part LG01.1 and the second linkage part LG01.2 and the line between the second limit end GG05.2.1b and the first limit end GG05.2.1a form an obtuse angle.

[0101] In some embodiments, Figure 1 As shown, the electric mechanism further includes a first spring TH04, and two ends of the first spring TH04 are respectively connected to the output component and the first connecting rod LG01, so that the first connecting rod LG01 has a tendency to maintain a current swing position. By setting the first spring TH04, the first connecting rod LG01 can not only swing relative to the output component, but also has a certain stability. Therefore, when the output component moves toward the actuating position, the first linkage part LG01.1 can be pressed against the second limit end GG05.2.1b or the fourth limit end GG05.2.3b under the action of the first spring TH04; and when the output component returns to the initial position, the first linkage part LG01.1 can leave the second limit end GG05.2.1b and press against the first limit end GG05.2.1a under the action of the first spring TH04, so as to have a tendency to slide along the second groove section GG05.2.2 toward the third limit end GG05.2.3a, or leave the fourth limit end GG05.2.3b and press against the third limit end GG05.2.3a, so as to have a tendency to slide along the second groove section GG05.2.2 toward the first limit end GG05.2.1a.

[0102] Specifically, combined Figure 1 , Fig.14 and Fig.15 As shown, the output component has a first connection position CT1.2.1, and the first connecting rod LG01 is connected to the first connection position CT1.2.1 of the output component through the second linkage part LG01.2. Optionally, the first connection position CT1.2.1 is a mounting hole, the second linkage part LG01.2 is a corresponding mounting hole set on the first connecting rod LG01, and the second linkage part LG01.2 and the first connection position CT1.2.1 are connected by a rotating shaft passing through both. In other embodiments, the second linkage part LG01.2 and the first connection position CT1.2.1 can also be one of the mounting hole and the other of the rotating shaft.

[0103] The output component is also provided with a second connecting position CT1.2.2, and the first connecting rod LG01 is provided with a third connecting position Z18. One end of the first spring TH04 is connected to the second connecting position CT1.2.2, and the other end of the first spring TH04 is connected to the third connecting position Z18, wherein the second connecting position CT1.2.2 and the third connecting position Z18 are respectively located on both sides of the first connecting position CT1.2.1, so that no matter which side of the output component the first connecting rod LG01 swings to, the first spring TH04 provides a pulling force to the first connecting rod LG01 to stabilize it on the current side.

[0104] The second connection position CT1.2.2 may be a shaft or a hole provided on the output component, and the third connection position Z18 may be a shaft or a hole provided on the first connecting rod LG01.

[0105] In the embodiment of the present application, the second connection position CT1.2.2 is an axis set on the output component, and the second connection position CT1.2.2 is set on the side of the output component away from the first side plate ZCB; the third connection position Z18 is an axis set on the first connecting rod LG01, and the third connection position Z18 is set on the side of the first connecting rod LG01 away from the first side plate ZCB and away from the first linkage part LG01.1, thereby avoiding interference between the first spring TH04 and components such as the output component, the first connecting rod LG01, the first lever GG05 and the first side plate ZCB, thereby ensuring stability.

[0106] When the output component is reset toward the initial position, the first link LG01 is driven to overcome the elastic force of the first spring TH04 and swing.

[0107] In the embodiment where the first electric component is the first electromagnet CT1, the force for the output component, i.e. the first iron core CT1.2, to return to the initial position is provided by the first return spring CT1.3, and the elastic force of the first return spring CT1.3 is greater than the elastic force of the first spring TH04. Figure 7 and Fig.12 As shown, when the output component is reset to the initial position, the first return spring CT1.3 provides a force Fj to the first linkage part LG01.1 through the output component, and the first spring TH04 provides a force Ft to the first linkage part LG01.1. The direction of Ft is opposite to that of Fj. By configuring the first return spring CT1.3 to have an elastic force greater than the elastic force of the first spring TH04, the component force of Fj along the second groove section GG05.2.2 can overcome the reaction force of the first spring TH04 in this direction, thereby achieving the purpose of driving the first linkage part LG01.1 to slide along the second groove section GG05.2.2.

[0108] In some embodiments, the structure of the first connecting rod LG01 is configured to also include a first supporting rod and a second supporting rod, the first supporting rod and the second supporting rod are arranged at intervals along the axial direction of the central axis ZXZ and are respectively located on both sides of the first lever GG05, one end of the first supporting rod and the second supporting rod are connected through the first linkage part LG01.1, and the connection between the first connecting rod LG01 and the first lever GG05 is more stable and has better mechanical properties. Optionally, the other ends of the first supporting rod and the second supporting rod are connected by rivets, screws or other anchors, so that the other ends of the first supporting rod and the second supporting rod are not easy to open relative to each other, ensuring that the second linkage part LG01.2 is stably connected to the output component.

[0109] In a second aspect, an embodiment of the present application provides a transfer switch, the transfer switch comprising a moving contact and the electric mechanism described in any one of the first aspects.

[0110] The moving contact has a first closing position and a second closing position.

[0111] In some embodiments, the transfer switch is used to control the switch states of the two power supplies, the first closing position is the position for connecting the first power supply, and the second closing position is the position for connecting the second power supply. For example, the first power supply is a normal power supply, and the second power supply is a backup power supply.

[0112] In other embodiments, the transfer switch is used to control the switch state of a power source, the first closing position is a position for connecting the first power source, and the second closing position is a position for disconnecting the first power source.

[0113] The central axis ZXZ of the aforementioned electric mechanism is transmission-connected to the moving contact, and the central axis ZXZ can rotate in the forward and reverse directions to drive the moving contact to move between the first closing position and the second closing position, thereby switching the switching state of the transfer switch.

[0114] In some embodiments, the switch further comprises a flip structure. Optionally, the flip structure is arranged on a side of the first side plate ZCB away from the electric component to prevent the flip structure from interfering with the electric component, the first lever GG05, the first connecting rod LG01, etc.

[0115] The flip structure includes a flip lever GG01, a flip spring TH01 and a first transmission member B02. The flip lever GG01 is rotatably arranged on the center axis ZXZ, the first transmission member B02 is fixedly arranged on the center axis ZXZ, and the two ends of the flip spring TH01 are respectively connected to the flip lever GG01 and the first transmission member B02.

[0116] The flip spring TH01 is configured to first store energy when the central axis ZXZ rotates, and then release the elastic potential energy to drive the flip lever GG01 to rotate rapidly in the opposite direction.

[0117] The central axis ZXZ is connected to the moving contact through the flip lever GG01. Specifically, the flip lever GG01 has a first rotation position and a second rotation position. When the flip lever GG01 is in the first rotation position, the moving contact is located in the first closing position; when the flip lever GG01 is in the second rotation position, the moving contact is located in the second closing position. The connection between the flip lever GG01 and the moving contact can be that the moving contact is directly set on the flip lever GG01, and the moving contact is connected to the flip lever GG01 through a connecting rod LG01 assembly or a gear assembly.

[0118] The first side plate ZCB is provided with a first flip limit axis Z03 and a second flip limit axis Z03', which are located on the rotation path of the flip lever GG01. The flip lever GG01 is abutted against the first flip limit axis Z03 to be positioned in the first rotation position, and the flip lever GG01 is abutted against the second flip limit axis Z03' to be positioned in the second rotation position.

[0119] like Figure 4 As shown, the central axis ZXZ includes a cylindrical fourth section ZXZ.4 and a shaped fifth section ZXZ.5. The fourth section ZXZ.4 and the fifth section ZXZ.5 are located on the side of the first side plate ZCB away from the first lever GG05.

[0120] like Fig.16 As shown, the flip lever GG01 is arranged in the fourth section ZXZ.4 so that the flip lever GG01 can rotate relative to the central axis ZXZ. The first transmission member B02 is arranged in the fifth section ZXZ.5 so that the first transmission member B02 is circumferentially fixed relative to the central axis ZXZ, thereby achieving synchronous rotation.

[0121] The flip lever GG01 is provided with a flip spring mounting part GG01.2, the first transmission part B02 is provided with a flip spring fixing part B02.2, the two ends of the flip spring TH01 are respectively connected to the flip spring mounting part GG01.2 and the flip spring fixing part B02.2, and when the center axis ZXZ rotates, the flip spring fixing part B02.2 is driven to rotate between the flip spring mounting part GG01.2 and the center axis ZXZ.

[0122] The flip spring mounting part GG01.2 and the center axis ZXZ have a first connecting line Bn-B, which is on the center line of the flip lever GG01, that is, the first connecting line Bn-B coincides with the geometric center line CC of the flip lever GG01 passing through the center axis ZXZ.

[0123] When the first transmission member B02 rotates in the positive direction (for example, counterclockwise) along with the central axis ZXZ, the flip spring fixing portion B02.2 rotates from one side of the first connecting line to the other side. Fig.17 As shown, the flip lever GG01 is located at the first rotation position, and the flip spring fixing part B02.2 is gradually compressed and stores elastic potential energy in the process of rotating counterclockwise close to the first connecting line. When the flip spring fixing part B02.2 is located on the first connecting line, the elastic potential energy of the flip spring TH01 is the largest, and the elastic force of the flip spring TH01 is along the first connecting line. The flip spring TH01 is at a compressed dead point position; at this time, if the central axis ZXZ continues to rotate counterclockwise, as shown in FIG. Fig.18 As shown, the flip spring fixing part B02.2 passes the dead point position, the flip spring TH01 releases elastic potential energy, and the flip spring TH01 generates a rightward component force along the tangent direction of its rotation path on the flip lever GG01, prompting the flip lever GG01 to rotate clockwise, that is, the flip lever GG01 rotates in the opposite direction relative to the first transmission member B02. Fig.19As shown, under the action of the flip spring TH01, the flip lever GG01 is opposite to the first transmission member B02 and rotates clockwise to the second rotation position, and the rotation speed of the flip lever GG01 under the actuation of the flip spring TH01 is faster than that of the flip lever GG01 directly driven by the central axis ZXZ, and the moving contact quickly switches to the second closing position, which can reduce the probability of arcing. At the same time, the flip lever GG01 abuts against the second flip limit axis Z03', so that it is fixed at the second rotation position, so that the moving contact remains in the second closing position.

[0124] Similarly, when the moving contact needs to be switched from the second closing position to the first closing position, the center axis ZXZ rotates in the opposite direction, for example, clockwise, the first transmission member B02 rotates in the opposite direction along with the center axis ZXZ, and the flip spring fixing portion B02.2 rotates from the other side of the first connecting line to one side, such as Fig. 20 As shown, the flip lever GG01 is located in the second rotation position, and the flip spring fixing part B02.2 is gradually compressed and stores elastic potential energy in the process of rotating clockwise close to the first connecting line. When the flip spring fixing part B02.2 is located on the first connecting line, the elastic potential energy of the flip spring TH01 is the largest, and the elastic force of the flip spring TH01 is along the first connecting line, and the flip spring TH01 is in a compressed dead point position; at this time, if the center axis ZXZ continues to rotate clockwise, the flip spring fixing part B02.2 will pass the dead point position and release the elastic potential energy, and the flip spring TH01 generates a left component force on the flip lever GG01 along the tangential direction of its rotation path, prompting the flip lever GG01 to rotate counterclockwise, that is, the flip lever GG01 rotates in the opposite direction relative to the first transmission member B02. Under the action of the flip spring TH01, the flip lever GG01 rotates counterclockwise toward the first rotation position in the opposite direction of the first transmission member B02, and the rotation speed is faster than that of the flip lever GG01 directly driven by the central axis ZXZ. The moving contact quickly switches to the first closing position, which can reduce the probability of arcing. Fig.16 In the state shown, the flip lever GG01 abuts against the first flip limit axis Z03, thereby being fixed in the first rotation position, so that the moving contact is maintained in the first closing position.

[0125] In some embodiments, the moving contact further has a double-open position, which is located between the first closing position and the second closing position. Fig.21 As shown, the flip lever GG01 also has a third rotation position for positioning the moving contact at the double-open position, and the third rotation position is located between the first rotation position and the second rotation position.

[0126] The conversion switch also includes a second lever GG07, a locking mechanism, and a second electric component. The second lever GG07 is movably arranged on the rotation path of the flip lever GG01, and the locking mechanism is used to lock the second lever GG07 on the rotation path of the flip lever GG01, so that the second lever GG07 can limit the flip lever GG01 to the third rotation position, so that the flip lever GG01 can only rotate between the first rotation position and the third rotation position, or can only rotate between the second rotation position and the third rotation position.

[0127] The second electric component is used to drive the locking mechanism to unlock the second lever GG07 to release the restriction of the second lever GG07 on the flip lever GG01, so that the flip lever GG01 can pass through the third rotation position to reach the first rotation position or the second rotation position.

[0128] Specifically, Figure 1 As shown, a flip lever limit axis Z13 is also provided on the flip lever GG01, and a first slot ZCB.2 is also provided on the first side plate ZCB. The first slot ZCB.2 is constructed as an arc slot extending circumferentially around the center axis ZXZ. When the flip lever GG01 moves between the first rotation position and the second rotation position, the flip lever limit axis Z13 moves between the two ends of the first slot ZCB.2.

[0129] There are various structures of the second lever GG07. For example, in some embodiments, the second lever GG07 is configured as a blocking component arranged in the middle position of the first slot ZCB.2, and the locking mechanism is used to limit the second lever GG07 from leaving the first slot ZCB.2. The second electric component is used to drive the locking mechanism to move so that the second lever GG07 can leave the first slot ZCB.2 and avoid the flip lever GG01.

[0130] In some embodiments of the present application, Fig. 22 As shown, the second lever GG07 is Y-shaped, one end of the second lever GG07 is configured with a first stopper GG07.1 and a second stopper GG07.2 arranged at intervals, and the other end of the second lever GG07 is configured with a third stopper GG07.3. Fig.23 Shown and Fig.24 As shown, the second lever GG07 is arranged on the first side plate ZCB or the first bracket ZJ01 through a rotating shaft, so that the first stop portion GG07.1 and the second stop portion GG07.2 of the second lever GG07 can swing at the first slot ZCB.2, and the third stop portion GG07.3 cooperates with the locking mechanism to lock the second lever GG07 in the current position, thereby limiting the swing of the second lever GG07, so that the first stop portion GG07.1 or the second stop portion GG07.2 is located in the middle position of the first slot ZCB.2.

[0131] like Fig.23 As shown in the figure, the second lever GG07 is locked by the locking mechanism, the first stopper GG07.1 is located in the middle of the first slot ZCB.2, and the second stopper GG07.2 is located at the right end of the first slot ZCB.2. When the flip lever GG01 is located in the first rotation position, the flip lever limit axis Z13 is located at the right end of the first slot ZCB.2. When the flip lever GG01 rotates toward the second closing position driven by the flip spring TH01, the flip lever limit axis Z13 is limited to the middle of the first slot ZCB.2, as shown in the figure. Fig.24 As shown, the flip lever GG01 is positioned in the third rotation position under the action of the flip spring TH01 and the first stop GG07.1.

[0132] The locking mechanism includes a first bracket ZJ01, a second bracket ZJ02 and a second spring TH03a. The first bracket ZJ01 is fixedly arranged on the first side plate ZCB, and the first bracket ZJ01 is provided with a fourth slot ZJ01.3, which is an arc slot extending roughly in the up and down direction. The left side of the second bracket ZJ02 is rotatably connected to the first bracket ZJ01, and the second spring TH03a is connected between the right side of the second bracket ZJ02 and the first side plate ZCB. The second bracket ZJ02 is provided with a bracket limit shaft Z23, and the bracket limit shaft Z23 is slidably penetrated in the fourth slot ZJ01.3, wherein the second spring TH03a has a tendency to rotate the second bracket ZJ02 upward, so that the bracket limit shaft Z23 is located at the upper end of the fourth slot ZJ01.3, and cooperates with the third stopper GG07.3 to lock the second lever GG07.

[0133] The second electric component includes a second electromagnet CT2. When the second electromagnet CT2 is energized, it pushes the second bracket ZJ02 to overcome the elastic force of the second spring TH03a and rotate downward, so that the bracket limit axis Z23 slides down along the fourth slot ZJ01.3 and leaves the third stop portion GG07.3 to release the lock on the second lever GG07.

[0134] After the second lever GG07 is unlocked, the flip lever GG01 moves toward the second rotation position under the action of the flip spring TH01, and the flip lever limit axis Z13 pushes the second lever GG07 to swing toward the right side of the first notch ZCB.2. Fig.25 and Fig.26 As shown, the second electromagnet CT2 is powered off, the second bracket ZJ02 rotates upward under the action of the second spring TH03a, and the bracket limit axis Z23 returns to the upper end of the fourth slot ZJ01.3, re-engages with the third stopper GG07.3 and locks the second lever GG07.

[0135] Similarly, after the second lever GG07 is re-locked, the flip lever GG01 is restricted from moving between the second rotation position and the third rotation position. If the second lever GG07 is unlocked by the second electromagnet CT2, the flip lever GG01 can reach the first rotation position again through the third rotation position.
