Description

Technical Field

[0001] This invention relates to the field of power switches, and more particularly to a two-position automatic transfer switch operating structure and transfer switch. Background Technology

[0002] Automatic transfer switches are common low-voltage electrical appliances, often used in important power distribution applications. They are used to switch between two power sources, ensuring a rapid switch to the backup power source when the primary power source fails, thus guaranteeing normal power supply to the load. The two-position automatic transfer switch operating structure is an important component of automatic transfer switch electrical appliances, and these appliances generally have both automatic and manual switching functions.

[0003] Currently, in existing technologies, traditional automatic transfer switches often employ a two-position automatic transfer switch operating structure with a main and backup circuit. During rotation, the direction of rotation of the contact assembly driven by the two-position automatic transfer switch operating structure is usually not on the same plane as the direction of rotation of the contact assembly system driven by the output shaft of the two-position automatic transfer switch operating structure; one rotates longitudinally, and the other rotates laterally. Therefore, gear or cam transmission is often used in two-position automatic transfer switch operating structures to change the direction of the output shaft. The gear or cam transmission method in two-position automatic transfer switch operating structures suffers from problems such as complex operating mechanisms, numerous parts, and high production costs. Furthermore, the complexity of the operating mechanism requires greater force for operation, making manual operation inconvenient. Summary of the Invention

[0027] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0028] like Figure 1 The diagram illustrates an operating structure for a two-position automatic transfer switch according to this embodiment, used to achieve automatic or manual switching of the main / backup circuit. This operating structure may include a support mechanism, a main / backup circuit switching mechanism, a first electromagnetic drive mechanism 8, and a second electromagnetic drive mechanism 10. The main / backup circuit switching mechanism is rotatably mounted on the support mechanism and connected to the moving contact assembly of the switch, used to drive the moving contact assembly on the two-position automatic transfer switch to perform main / backup switching. The first electromagnetic drive mechanism 8 and the second electromagnetic drive mechanism 10 are symmetrically mounted on both sides of the support mechanism, providing driving force when the main / backup circuit switching mechanism performs main / backup circuit switching, thereby achieving automatic switching of the main / backup circuit.

[0029] like Figure 2 , Figure 3As shown, in some embodiments, the support mechanism may include two support plates 1; the two support plates 1 are symmetrically arranged facing each other from the sides, and each support plate 1 has several threaded holes, for example, three, arranged in a triangle on the support plate 1; wherein, two threaded holes are located on the lower part of the support plate 1, and one threaded hole is located on the upper part of the support plate 1. It should be noted that the threaded holes penetrate the support plate 1 along the thickness direction, and the two support plates 1 are connected by screws. It should also be noted that the main / backup switching mechanism is installed between the two support plates 1, so there is a certain accommodating space between the connected two support plates 1 to accommodate the main / backup switching mechanism.

[0030] Furthermore, in some embodiments, the support plate 1 may include a first sub-support plate 1J and a second sub-support plate 1k; the support plate 1 may be integrally formed, or the first sub-support plate 1J and the second sub-support plate 1k may be connected by a fixed connection.

[0031] The first sub-support plate 1J may be a square plate, but is not limited to a square plate; the first sub-support plate 1J may include a first through hole 1m. The first through hole 1m penetrates the first sub-support plate 1J along the thickness direction of the first sub-support plate 1J.

[0032] The first through hole 1m is located above the first sub-support plate 1J.

[0033] The second sub-support plate 1k is fixedly connected to the first sub-support plate 1J by welding. The connection end between the second sub-support plate 1k and the first sub-support plate 1J adopts an inward folding design, making the second sub-support plate 1k approximately L-shaped. The support plate 1 is fixedly connected to the first electromagnetic drive mechanism 8 or the second electromagnetic drive mechanism 10 through the inward folding part. The connection method can be a threaded connection, but is not limited to a threaded connection.

[0034] The second sub-support plate 1k may include a first support post 1a, a first limiting post 1d, a second limiting post 1f, a third limiting post 1b, a fourth limiting post 1h, a first coupling post 1c, a second coupling post 1g, and a third coupling post 1e. The first support post 1a, the first limiting post 1d, the second limiting post 1f, the third limiting post 1b, the fourth limiting post 1h, the first coupling post 1c, and the second coupling post 1g all extend outward along the thickness direction of the support plate 1; the third coupling post 1e extends inward along the thickness direction of the support plate 1. In this embodiment, the first support column 1a is located at the middle position of the second sub-support plate 1k; the first limiting column 1d is located above the support plate 1 and close to the first electromagnetic drive mechanism 8; the second limiting column 1f is symmetrically arranged with the first limiting column 1d; the third limiting column 1b is located close to the first electromagnetic drive mechanism 8; the fourth limiting column 1h is symmetrically arranged with the third limiting column 1b; the first coupling column 1c is located close to the first electromagnetic drive mechanism 8; the second coupling column 1g is symmetrically arranged with the first coupling column 1c close to the second electromagnetic drive mechanism 10; and the third coupling column 1e is located above the second sub-support plate 1k.

[0035] like Figure 2As shown, in some embodiments, the main / backup switching mechanism may include a first rotating shaft 4, a first bracket 5, a first connecting assembly, a rocker arm 3, an elastic component, an operating bracket 2, a first transmission assembly 9, and a second transmission assembly 11. The first rotating shaft 4 is rotatably mounted on a support mechanism and extends one end out of the support mechanism, used to drive the switch contacts to switch between the main and backup circuits. The first bracket 5 is fixedly mounted on the first rotating shaft 4, used to drive the first rotating shaft 4 to rotate. The first connecting assembly is slidably connected to the first bracket 5, used to drive the first bracket 5 and the rocker arm 3 to rotate. One end of the rocker arm 3 is rotatably mounted on the support mechanism, and the other end of the rocker arm 3 is rotatably mounted on the first connecting assembly, used to generate varying pressure to press the first connecting assembly. One end of the elastic component is connected to the operating bracket 2, and the other end of the elastic component is connected to the first connecting assembly, to generate a pulling force acting on the first connecting assembly. The operating bracket 2 is rotatably mounted on the support mechanism and is located between the first limiting post 1d and the second limiting post 1f. One end of the first transmission component 9 is connected to the first electromagnetic drive mechanism 8, and the other end of the first transmission component 9 is rotatably connected to the operating bracket 2. After the first electromagnetic drive mechanism 8 provides driving force, the first transmission component 9 transmits the driving force to the operating bracket 2, causing the operating bracket 2 to rotate. One end of the second transmission component 11 is connected to the second electromagnetic drive mechanism 10, and the other end of the second transmission component 11 is rotatably connected to the operating bracket 2. After the second electromagnetic drive mechanism 10 provides driving force, the second transmission component 11 transmits the driving force to the operating bracket 2, causing the operating bracket 2 to rotate. It should be noted that the first electromagnetic drive mechanism 8 and the second electromagnetic drive mechanism 10 are symmetrically arranged. Therefore, when the first electromagnetic drive mechanism 8 generates driving force, the direction of rotation of the operating bracket 2 is opposite to the direction of rotation of the operating bracket 2 when the second electromagnetic drive mechanism 10 generates driving force. In addition, the first electromagnetic drive mechanism 8 and the second electromagnetic drive mechanism 10 cannot provide driving force to the operating bracket 2 simultaneously.

[0036] Specifically, one end of the first rotating shaft 4 is rotatably mounted on the first through hole 1m of a support plate 1, and the other end of the first rotating shaft 4 passes through the first through hole 1m of another support plate 1 and extends out of the support plate 1. The switch contact is mounted on the end of the first rotating shaft 4 that extends out of the support plate 1 so as to drive the switch contact to switch between the main and backup circuits when the first rotating shaft 4 rotates; wherein, the first rotating shaft 4 may be a square shaft, but is not limited to a square shaft.

[0037] The first connecting assembly may include a second rotating shaft 6; the second rotating shaft 6 is slidably mounted on the first bracket 5. It should be noted that the second rotating shaft 6 slides on the first bracket 5 in the radial direction along the first rotating shaft 4.

[0038] like Figure 4As shown, in some embodiments, the first bracket 5 may include a first connecting plate 5a, a second connecting plate 5b, and a third connecting plate 5c; both the first connecting plate 5a and the second connecting plate 5b are elongated elliptical in shape. One end of the first connecting plate 5a can be fixedly connected to the first rotating shaft 4. Specifically, the connection end of the first connecting plate 5a and the first rotating shaft 4 may be provided with a square hole penetrating the first connecting plate 5a along the thickness direction of the first connecting plate 5a. The first connecting plate 5a is fitted onto the first rotating shaft 4 through the square hole, and the first connecting plate 5a and the first rotating shaft 4 are fixedly connected by welding. The other end of the first connecting plate 5a is provided with an oblong hole penetrating the first connecting plate 5a along the thickness direction of the first connecting plate 5a. The width of the oblong hole is slightly larger than the outer diameter of the second rotating shaft 6, and the length of the oblong hole is larger than the outer diameter of the second rotating shaft 6, so that the second rotating shaft 6 has sliding space along the length direction of the first connecting plate 5a. The second connecting plate 5b is arranged parallel to the first connecting plate 5a. One end of the second connecting plate 5b is fixedly connected to the first rotating shaft 4 using the same connection method as the first connecting plate 5a. The other end of the second connecting plate 5b is provided with an oblong hole of the same size and position as the one on the first connecting plate 5a. The oblong hole is designed to meet the requirement of the second rotating shaft 6 sliding radially along the first rotating shaft 4. The third connecting plate 5c is a square plate. One end of the third connecting plate 5c is connected to the first connecting plate 5a sleeved on the first rotating shaft 4, and the other end of the third connecting plate 5c is connected to the second connecting plate 5b sleeved on the first rotating shaft 4. The third connecting plate 5c is fixedly connected to the first rotating shaft 4, thus making the connection between the first connecting plate 5a, the second connecting plate 5b, and the first rotating shaft 4 more secure. The second rotating shaft 6, the first connecting plate 5a, the second connecting plate 5b, and the third connecting plate 5c are all located within the accommodating space between the two symmetrically arranged support plates 1. The second rotating shaft 6 is arranged parallel to the first rotating shaft 4. One end of the second rotating shaft 6 is slidably installed in the waist-shaped hole of the first connecting plate 5a, and the other end of the second rotating shaft 6 is slidably installed in the waist-shaped hole of the second connecting plate 5b, so that the second rotating shaft 6 can slide radially along the first rotating shaft 4 on both the first connecting plate 5a and the second connecting plate 5b.

[0039] Furthermore, in another embodiment, the first bracket 5 may be configured as a cubic block, one end of which is fixedly connected to the first rotating shaft 4, and the other end of which may be provided with a waist-shaped hole that penetrates the cubic block, through which the second rotating shaft 6 is slidably installed in the cubic block along the radial direction of the first rotating shaft 4.

[0040] like Figure 2As shown, in some embodiments, the rocker arm 3 is an oblong plate; however, it is not limited to an oblong plate, for example, it can be a square plate. One end of the rocker arm 3 is rotatably mounted inside the support plate 1, and the other end of the rocker arm 3 is rotatably connected to one end of the second rotating shaft 6. Specifically, two rocker arms 3 can be provided; one rocker arm 3 is rotatably mounted at one end of the second rotating shaft 6, and the other end of the rocker arm 3 is rotatably coupled to a third coupling post 1e on the support plate 1 near the rocker arm 3; the other rocker arm 3 is rotatably mounted at the other end of the second rotating shaft 6, and the other end of the rocker arm 3 is rotatably coupled to a third coupling post 1e on the support plate 1 near the rocker arm 3.

[0041] Furthermore, in another embodiment, the first connecting component may include a first connecting post and a second connecting post; one end of the first connecting post is slidably mounted on a waist-shaped hole on the first connecting plate 5a, and the other end of the first connecting post is rotatably connected to one end of the rocker arm 3 near the first connecting post; one end of the second connecting post is slidably mounted on a waist-shaped hole on the second connecting plate 5b, and the other end of the second connecting post is rotatably connected to one end of the rocker arm 3 near the second connecting post.

[0042] Furthermore, in another embodiment, positioning pins can be added to both ends of the second rotating shaft 6. The positioning pins are installed on the outside of the rocker arm 3 and abut against the rocker arm 3 to prevent the rocker arm 3 from moving away from the second rotating shaft 6 during rotation.

[0043] like Figure 1 As shown, in some embodiments, the elastic component may include several tension springs 7, for example, two. The two tension springs 7 may be arranged in parallel. One end of the tension spring 7 is connected to the second rotating shaft 6, and the other end of the tension spring 7 is connected to the operating bracket 2.

[0044] Furthermore, the elastic component can also be an elastic rubber ring, with one end of the elastic rubber ring connected to the operating bracket 2 and the other end of the elastic rubber ring connected to the second rotating shaft 6; of course, the elastic component can also be other tension components, such as a rubber band, with a hook at each end of the rubber band, one end of which is connected to the operating bracket 2 and the other end of which is connected to the second rotating shaft 6.

[0045] Furthermore, in another embodiment, the number of tension springs 7 may be set to other quantities, such as three, depending on the application.

[0046] like Figure 1 , Figure 2 As shown, in some embodiments, the operating bracket 2 may include a frame 2a and an operating handle 2b; the operating handle 2b is disposed above the frame 2a. The frame 2a is rotatably mounted on two support plates 1.

[0047] Specifically, the frame 2a may be roughly arch-shaped, but is not limited to an arch shape. The frame 2a may include a top plate and side plates; the top plate may be a square plate, with a through groove 2c extending through the top plate along its thickness direction, and a crossbar 2d intersecting the through groove 2c. Several through grooves 2c may be provided, for example, two; the through grooves 2c may be square grooves, but are not limited to square grooves; the through grooves 2c are arranged parallel to each other on the top plate. The width of the through groove 2c is much smaller than the width of the top plate, and the length of the through groove 2c is less than the length of the top plate. The crossbar 2d is column-shaped, but is not limited to column-shaped; there may be two crossbars 2d, the axial length of which is greater than the width of the square groove, and the crossbar 2d intersects the through groove 2c perpendicularly along its width direction. A crossbar 2d is provided on each through slot 2c, dividing each through slot 2c into two halves. A tension spring 7 enters from one half of the slot and exits from the other half, thus connecting the tension spring 7 to the operating bracket 2. It should be noted that the arrangement of the through slot 2c and the crossbar 2d must ensure that the tension spring 7 can also rotate in the same direction as the operating bracket 2 during rotation. It should be noted that "rotation in the same direction" means that as the operating bracket 2 drives the tension spring 7 to rotate, the rotation direction of the tension spring 7 is consistent with the rotation direction of the operating bracket 2.

[0048] The operating handle 2b is cylindrical, but not limited to cylindrical. It can be positioned between two square slots. When manual switching between the main and backup circuits is required, the operating handle 2b drives the operating bracket 2 to rotate, which in turn drives the first rotating shaft 4 to rotate in the same direction, thus achieving the switching between the main and backup circuits. The operating handle 2b is directly mounted on the frame 2a, eliminating the need for a separate operating handle 2b and avoiding the problem of easy loss associated with traditional two-position automatic switch operating handles 2b.

[0049] Several side plates can be provided, for example, two. These side plates are symmetrically arranged on both sides of the top plate and parallel to the support plate 1. The side plates can be approximately square in shape and are connected to the top plate by welding. Each side plate has symmetrically arranged protrusions along its length, and each protrusion extends outward along the thickness of the side plate, providing a fourth coupling post 2f. The operating bracket 2 is rotatably coupled to the two support plates 1 through the fourth coupling post 2f. Furthermore, a second through hole 2e is provided below the side plate along its thickness. This second through hole 2e can be approximately Ω-shaped, and the operating bracket 2 is rotatably mounted on the first support post 1a through the second through hole 2e. It should be noted that the diameter of the second through hole 2e is slightly larger than the diameter of the first support post 1a, and the opening size at the open end is smaller than the diameter of the first support post 1a.

[0050] like Figure 1 , Figure 2As shown, in some embodiments, the first transmission assembly 9 may include two first connecting rods 9a, two first sub-connecting rods 9c, and a first connecting shaft 9b. The first connecting shaft 9b passes through the first electromagnetic drive mechanism 8, and its two ends are located on both sides of the first electromagnetic mechanism. The two first connecting rods 9a are symmetrically arranged on both sides of the support mechanism, and the two first connecting rods 9a are installed in the same way. Specifically, the first connecting rod 9a is installed between the first limiting post 1d and the third limiting post 1b, and is parallel to the support plate 1. The first limiting post 1d limits the movement of the first connecting rod 9a. One end of the two first connecting rods 9a is symmetrically connected to both ends of the first connecting shaft 9b, and the other end of the two first connecting rods 9a is rotatably connected to one end of the first sub-connecting rod 9c. The middle position of the first connecting rod 9a is rotatably coupled to the outside of the support plate 1 through the first coupling post 1c, so that the first connecting rod 9a acts as a fulcrum to drive the first sub-connecting rod 9c to rotate during rotation. Two first sub-links 9c are symmetrically arranged on both sides of the support mechanism. The two first sub-links 9c are installed in the same way. Specifically, the other end of the first sub-link 9c is provided with an oblong hole. Through the oblong hole, the first sub-link 9c can be rotatably coupled to the fourth coupling column 2f on the operating bracket 2 and on the side close to the first electromagnetic drive mechanism 8.

[0051] like Figure 1 , Figure 2 As shown, in some embodiments, the second transmission assembly 11 may include two second connecting rods 11a, two second sub-connecting rods 11b, and a second connecting shaft 11c. The second connecting shaft 11c passes through the second electromagnetic drive mechanism 10, and its two ends are located on both sides of the second electromagnetic mechanism. The two second connecting rods 11a are symmetrically arranged on both sides of the support mechanism, and the two second connecting rods 11a are installed in the same way. Specifically, the second connecting rod 11a is installed between the second limiting post 1f and the fourth limiting post 1h, and is parallel to the support plate 1. One end of the second connecting rod 11a is connected to one end of the second connecting shaft 11c, and the other end of the second connecting rod 11a is rotatably connected to the second sub-connecting rod 11b. The middle position of the second connecting rod 11a is rotatably coupled to the outside of the support plate 1 through the second coupling post 1g, so that the second connecting rod 11a acts as a fulcrum to drive the second sub-connecting rod 11b to rotate during rotation. The two second sub-links 11b are installed in the same way. Specifically, the other end of the second sub-link 11b is provided with an oblong hole, through which the second sub-link 11b can be rotatably coupled to the fourth coupling column 2f on the operating bracket 2 and near the side of the second electromagnetic drive mechanism 10. In this embodiment, the first link 9a, the first sub-link 9c, the second link 11a, and the second sub-link 11b are all installed on the outside of the two support plates 1; of course, the first link 9a, the first sub-link 9c, the second link 11a, and the second sub-link 11b can also be installed on the inside of the two support plates 1. It should be noted that the first link 9a and the first sub-link 9c need to be installed on the same side; the second link 11a and the second sub-link 11b also need to be installed on the same side.

[0052] like Figure 1 , Figure 2 As shown, in some embodiments, the first electromagnetic drive mechanism 8 may include a first electromagnetic drive bracket 8a, a first spring 8b, a first electromagnetic coil, a first moving iron core 8c, and a first stationary iron core. One end of the first spring 8b is fixedly mounted on the first electromagnetic drive bracket 8a, and the other end of the first spring 8b extends upward along the central axis of the first spring 8b, providing power to reset the first moving iron core 8c after the first electromagnetic coil is de-energized. The first electromagnetic coil is installed between the first moving iron core 8c and the first stationary iron core, providing driving force for the attraction between the first moving iron core 8c and the first stationary iron core. The first moving iron core 8c is movably inserted into the first spring 8b along the central axis of the first spring 8b. The first stationary iron core and the first moving iron core 8c are arranged vertically opposite each other.

[0053] Specifically, the first electromagnetic drive bracket 8a can be roughly arch-shaped. The first electromagnetic drive bracket 8a can be formed in one piece, or it can be composed of several top plates and several side plates. There can be one top plate, with a through-hole along its thickness direction. The diameter of the third through-hole must allow the first moving iron core 8c to pass through, and must be smaller than the outer diameter of the first spring 8b. There can be two side plates, positioned opposite each other on either side of the top plate. Furthermore, the lower side of the side plates adopts an outward folding design, making the side plates L-shaped, and the first electromagnetic drive bracket 8a is fixed by the outward folding portion.

[0054] One end of the first spring 8b is fixedly installed above the top plate of the first electromagnetic drive bracket 8a; it should be noted that the first spring 8b must be installed coaxially with the third through hole during installation.

[0055] The first moving iron core 8c is cylindrical and is movably inserted into the first spring 8b along the central axis of the first spring 8b. A fourth through hole is provided at the end of the first moving iron core 8c away from the first stationary iron core, and the central axis of the fourth through hole intersects perpendicularly with the central axis of the first moving iron core 8c. The first connecting shaft 9b is inserted into the fourth through hole. It should be noted that the axial length of the first connecting shaft 9b is greater than the outer diameter of the first spring 8b, so that the first connecting shaft 9b can overlap the extension end of the first spring 8b, so as to ensure that the first moving iron core 8c can compress the first spring 8b through the first connecting shaft 9b during the attraction process with the first stationary iron core.

[0056] The first stationary iron core is fixedly installed on the first electromagnetic drive bracket 8a and is positioned opposite to the first moving iron core 8c to ensure that the first stationary iron core and the first moving iron core 8c can be attracted together when the first electromagnetic coil is energized.

[0057] like Figure 1 , Figure 2As shown, in some embodiments, the second electromagnetic drive mechanism 10 may include a second electromagnetic drive bracket 10a, a second spring 10b, a second electromagnetic coil, a second moving iron core 10c, and a second stationary iron core. One end of the second spring 10b is fixedly mounted on the second electromagnetic drive bracket 10a, and the other end of the second spring 10b extends upward along the central axis of the second spring 10b, providing power to reset the second moving iron core 10c after the second electromagnetic coil is de-energized. The second electromagnetic coil is installed between the second moving iron core 10c and the second stationary iron core, providing driving force for the attraction between the second moving iron core 10c and the second stationary iron core. The second moving iron core 10c is movably inserted into the second spring 10b along the central axis of the second spring 10b. The second stationary iron core and the second moving iron core 10c are arranged vertically opposite each other.

[0058] Specifically, the second electromagnetic drive bracket 10a can be roughly arch-shaped. The second electromagnetic drive bracket 10a can be formed in one piece, or it can be composed of several top plates and several side plates. There can be one top plate, with a fifth through hole extending through the top plate along its thickness direction. The diameter of the fifth through hole must allow the second moving iron core 10c to pass through, and must be smaller than the outer diameter of the second spring 10b. There can be two side plates, positioned opposite each other on either side of the top plate. Furthermore, the lower side of the side plates adopts an outward fold design, making the side plates outward L-shaped, and the second electromagnetic drive bracket 10a is fixed through the outward fold.

[0059] One end of the second spring 10b is fixedly installed above the top plate of the second electromagnetic drive bracket 10a; it should be noted that the first spring 8b must be installed coaxially with the fifth through hole during installation.

[0060] The second moving iron core 10c is cylindrical and is movably inserted into the second spring 10b along the central axis of the second spring 10b. A sixth through hole is provided at the end of the second moving iron core 10c away from the second stationary iron core, and the central axis of the sixth through hole intersects perpendicularly with the central axis of the second moving iron core 10c. The second connecting shaft 11c is inserted into the sixth through hole. It should be noted that the axial length of the second connecting shaft 11c is greater than the outer diameter of the second spring 10b, so that the second connecting shaft 10b can overlap the extension end of the second spring 10b, so as to ensure that the second moving iron core 10c can compress the second spring 10b through the second connecting shaft 11c during the attraction process with the second stationary iron core.

[0061] The second stationary iron core is fixedly installed on the second electromagnetic drive bracket 10a and is positioned vertically opposite to the second moving iron core 10c to ensure that the second stationary iron core and the second moving iron core 10c can be attracted together when the second electromagnetic coil is energized.

[0062] like Figure 2As shown, the two-position automatic transfer switch structure of the present invention is assembled as follows: First, the first bracket 5 and the first rotating shaft 4 are installed. After installation, the second rotating shaft 6 is installed on the first bracket 5, and the two rocker arms 3 are installed at both ends of the second rotating shaft 6. The assembled components are installed between the two support plates 1, wherein one end of the first rotating shaft 4 extends into a support plate 1 along the thickness direction of the support plate 1. Then, the two rocker arms 3 are rotatably installed on the inner side of the corresponding support plates 1. After installation, one end of the tension spring 7 is connected to the second rotating shaft 6, and the other end of the tension spring 7 is connected to the operating bracket 2. Then, the operating bracket 2 is installed on the two support plates 1. Finally, one side of the two support plates 1 is connected to the first electromagnetic drive mechanism 8 through the first transmission assembly 9, and the other side of the two support plates 1 is connected to the second electromagnetic drive mechanism 10 through the second transmission assembly 11. The two ends of the two support plates 1 are respectively fixedly installed on the first electromagnetic drive mechanism 8 and the second electromagnetic drive mechanism 10.

[0063] The two-stage automatic transfer switch structure of the present invention can be divided into two main and backup circuit switching modes during operation: one is manual switching of the main and backup circuits; the other is automatic switching of the main and backup circuits.

[0064] When manually switching between the main circuit and the standby circuit: Manually move the switch 13 towards the main circuit side. The switch 13 transmits driving force to the operating bracket 2, causing the operating bracket 2 to pull the tension spring 7 to generate tension on the second rotating shaft 6. As the operating bracket 2 continues to rotate, the tension gradually increases. The tension spring 7 stores energy in the stretched state. When the operating bracket 2 rotates to a certain position, the tension is greater than the pressing force of the rocker arm 3 on the second rotating shaft 6. The tension spring 7 starts to drive the second rotating shaft 6 to rotate. The second rotating shaft 6 drives the first bracket and the rocker arm 3 to rotate. The first bracket drives the first rotating shaft 4 to rotate in the same direction as the operating bracket 2. At the same time, the second rotating shaft 6 slides radially on the first bracket along the first rotating shaft 4. At this time, the tension and pressing forces continue to change. When rotating towards the main circuit side, when the pressing force is greater than the tension, the first rotating shaft 4 continues to rotate to the closed position. The pressing force of the rocker arm 3 presses the first rotating shaft 4 into the main circuit closed position. At this time, the switching is completed. It should be noted that when switching to the backup circuit is required, the switch 13 is flipped on the backup circuit side; at this time, the movement process of the two-position automatic transfer switch structure is the same as the movement process when switching to the main circuit, and will not be described again here.

[0065] like Figures 5-8As shown, when automatically switching between the main circuit and the backup circuit, the first electromagnetic drive mechanism 8 is installed on the main circuit side, and the second electromagnetic drive mechanism 10 is installed on the backup circuit side. Specifically, when the first electromagnetic drive mechanism 8 switches, the first electromagnetic coil in the first electromagnetic drive mechanism 8 is energized to generate magnetic force, causing the first moving iron core 8c to attract the first stationary iron core. The first moving iron core 8c moves downward along the central axis of the first spring 8b. During the movement, the first spring 8b is pressed down through the first connecting shaft 9b. At the same time, the operating bracket 2 is driven to rotate towards the main circuit side. The operating bracket 2 pulls the tension spring 7 to generate tension on the second rotating shaft 6. As the operating bracket 2 continues to rotate, the tension gradually increases. The tension spring 7 stores energy in the stretched state. When the operating bracket 2 rotates to a certain position... When the tension force exceeds the pressing force of the rocker arm 3 on the second rotating shaft 6, the tension spring 7 begins to drive the second rotating shaft 6 to rotate. The second rotating shaft 6 drives the first bracket and the rocker arm 3 to rotate. The first bracket drives the first rotating shaft 4 to rotate in the same direction as the operating bracket 2. At the same time, the second rotating shaft 6 slides radially along the first rotating shaft 4 on the first bracket. At this time, the tension and pressing forces continue to change. When rotating towards the main circuit side, the pressing force changes to be greater than the tension force. The first rotating shaft 4 continues to rotate to the closing position. After the closing position, the pressing force is greater than the tension force. The pressing force of the rocker arm 3 presses the first rotating shaft 4 into the main circuit closing position. At this time, the switching is completed. When switching to the backup circuit, the first electromagnetic coil is de-energized, the first spring 8b releases energy, and drives the first moving iron core 8c to reset via the first connecting shaft 9b. At this time, the second electromagnetic coil is energized to generate electromagnetic force, causing the second moving iron core 10c to attract the second stationary iron core. The second moving iron core 10c moves downward along the central axis of the second spring 10b. During the movement, it presses down on the second spring 10b via the second connecting shaft 11c. Simultaneously, it drives the operating bracket 2 to rotate towards the backup circuit side. The operating bracket 2 pulls the tension spring 7 to generate tension on the second rotating shaft 6. When the operating bracket 2 rotates to a certain position, the tension... When the pressing force of the rocker arm 3 on the second rotating shaft 6 is greater than the pressing force of the rocker arm 3, the tension spring 7 begins to drive the second rotating shaft 6 to rotate. The second rotating shaft 6 drives the first bracket and the rocker arm 3 to rotate. The first bracket drives the first rotating shaft 4 to rotate in the same direction as the operating bracket 2. At the same time, the second rotating shaft 6 slides radially along the first rotating shaft 4 on the first bracket. At this time, the tension and pressing forces continue to change. When rotating towards the main circuit side, the pressing force changes to be greater than the tension force, and the first rotating shaft 4 continues to rotate to the closed position. After the closed position, the pressing force is greater than the tension force, and the pressing force of the rocker arm 3 presses the first rotating shaft 4 into the main circuit closed position. At this time, the switching is completed. It should be noted that the first electromagnetic drive mechanism 8 and the second electromagnetic drive mechanism 10 have the same structure. The first electromagnetic drive mechanism 8 can also be used on the standby circuit switching side, and the second electromagnetic drive mechanism 10 can also be used on the main circuit switching side. In addition, the rotation direction when the second electromagnetic drive mechanism 10 is energized and drives the operating bracket 2 to rotate is opposite to the rotation direction when the first electromagnetic drive mechanism 8 is energized and drives the operating bracket 2 to rotate.The first rotating shaft 4 rotates in the same direction as the operating bracket 2 during rotation, eliminating the need for reversing direction and significantly reducing parts and production costs. Simultaneously, the co-rotation reduces operating force. It should be noted that the "co-rotation" of the first rotating shaft 4 and the operating bracket 2 is not a fixed direction, but rather depends on the rotation direction of the operating bracket 2. It can rotate clockwise or counterclockwise; that is, when the operating bracket 2 rotates clockwise, the first rotating shaft 4 rotates clockwise, and when the operating bracket 2 rotates counterclockwise, the first rotating shaft 4 rotates counterclockwise.

[0066] like Figure 9 , Figure 10 As shown, this invention provides a two-position automatic transfer switch, which may include a housing assembly, a two-position automatic transfer switch structure, a moving contact assembly, a main circuit stationary contact assembly, and a backup circuit stationary contact assembly. The two-position automatic transfer switch structure is installed inside the housing assembly; the moving contact assembly is installed on the extension of the first rotating shaft 4; the main circuit stationary contact assembly and the backup circuit stationary contact assembly are installed opposite each other on the housing assembly, and the main circuit contact assembly and the backup circuit stationary contact assembly are located on opposite sides of the first rotating shaft 4, so that when the first rotating shaft 4 drives the moving contact assembly to rotate, it couples with the main circuit stationary contact assembly or the backup circuit stationary contact assembly; specifically, the electromagnetic drive mechanism provides driving force to drive the operating bracket 2 to rotate, the operating bracket 2 drives the first rotating shaft 4 to rotate, and then drives the moving contact assembly to realize the switching of the main and backup power supplies.

A square hole is provided on the upper wall of the first housing 12, and the switch 13 is installed in the square hole on the upper wall of the first housing 12 and extends outward from the first housing 12 along the thickness direction of the upper wall of the first housing 12. The switch 13 is fixedly connected to the operating handle 2b, and the main and backup power supplies are manually switched by means of the switch 13.

[0069] like Figure 10As shown, in some embodiments, the second housing 14 is disposed on the side of the second rotating shaft 6 extending from the first housing 12 and is adjacent to the first housing 12, such that the portion of the first rotating shaft 4 extending from the first housing 12 is located within the second housing 14. The second housing 14 is provided with several connection channels, for example, four; the connection channels are arranged perpendicularly to the first rotating shaft 4. In this embodiment, the main circuit switch contact and the standby circuit switch contact are mounted opposite each other at both ends of the connection channel, and the moving contact assembly is correspondingly mounted on the first rotating shaft 4. The first rotating shaft 4 drives the moving contact assembly to rotate, thereby closing with the main circuit switch contact or the standby circuit switch contact; wherein, an isolation plate is provided between each connection channel. It is understood that the number of connection channels can be expanded according to the actual application.

[0070] It is understood that the above embodiments only illustrate preferred embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention.
