Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical technology, and in particular to an operating mechanism and an automatic transfer switch. Background Technology

[0002] Automatic transfer switches (ATSEs) are primarily used to automatically switch between mains and backup power to ensure power continuity. Their core function is to quickly disconnect the mains power circuit and connect the backup power when a mains power failure (such as a power outage or abnormal voltage) is detected; and to automatically or manually switch back to the mains power when the mains power is restored. ATSEs are widely used in hospitals, data centers, industrial facilities, and other locations with extremely high power reliability requirements.

[0003] Because ATSE equipment requires bidirectional opening / closing, the operating mechanism must be able to operate in both directions, and the force required for opening / closing in both directions must be consistent. For example, the operating mechanism needs to be able to drive the handle to reciprocate between the normally closed position and the standby closed position. Some switches use the forward and reverse rotation of a motor to achieve the forward and reverse movement of the operating mechanism, but the motor's response is relatively slow. Therefore, existing ATSE technologies typically use electromagnets as the drive mechanism to achieve rapid action. To achieve the reversing action of the operating mechanism, two electromagnets are usually used for separate driving.

[0004] The above solution has the following drawbacks: the manufacturing cost of electromagnets is high, using dual electromagnets will increase the cost of switching equipment, and since it is necessary to reserve installation space for two electromagnets and connect both electromagnets to the operating handle through a linkage mechanism, it occupies a large space and the assembly process is complicated, which is not conducive to the miniaturization of the equipment.

[0005] Therefore, there is an urgent need for an operating mechanism and an automatic transfer switch to solve the above-mentioned problems in the existing technology. Utility Model Content

[0040] And / or,

[0041] The first guide hole extends in an arc shape, a V shape, or a U shape.

[0042] On the other hand, an automatic transfer switch is provided, including a housing and an operating mechanism for the automatic transfer switch as described above, the operating mechanism being disposed in the housing.

[0043] The beneficial effects of this utility model are:

[0044] This invention provides an operating mechanism for an automatic transfer switch. The rotating shaft assembly can reciprocate between a first closed position and a second closed position to switch the operating state of the automatic transfer switch. By providing a first guide hole on the bracket, and making the middle reversing position of the first guide hole further away from the drive assembly than its first and second ends, an opening towards the drive assembly is formed between the first and second ends of the first guide hole. When the electromagnetic mechanism has not yet generated a magnetic force on the moving iron core, the transmission assembly is located in the middle reversing position. When the rotating shaft assembly needs to switch positions, the electromagnetic mechanism generates a magnetic attraction force on the moving iron core, causing the moving iron core to pull the transmission assembly from the middle reversing position towards the first or second end of the first guide hole under the magnetic attraction force of the electromagnetic mechanism. This, in turn, drives the rotating shaft assembly to rotate towards the first or second closed position, achieving position switching and thus switching the operating state of the automatic transfer switch. This operating mechanism requires only one drive assembly, and bidirectional movement of the operating mechanism can be achieved by making the transmission assembly move in both directions. It offers high reliability, low cost, small space occupation, and simplified assembly process.

[0045] Because the intermediate reversing position is farther from the drive assembly than the first and second ends of the first guide hole, the transmission assembly is subjected to the pulling force of the moving iron core when it moves towards the two ends of the first guide hole, rather than the pushing force of the moving iron core. Compared with the method of using an electromagnetic mechanism to repel the moving iron core and push the transmission assembly further away, the method of using an electromagnetic mechanism to magnetically attract the moving iron core and use the moving iron core to provide the pulling force to move the transmission assembly, thereby achieving the switching between the first and second closing positions, is technically easier to implement and structurally simpler. It can effectively reduce the difficulty of assembling and coordinating the electromagnetic mechanism and the moving iron core, reduce production costs and improve production efficiency. Moreover, the solution of using the moving iron core to provide the pulling force to achieve the switching of the closing position has higher reliability and a relatively lower failure rate in switch products, thus improving the overall competitiveness of the product.

[0046] This utility model also provides an automatic transfer switch. Because it includes the above-mentioned operating mechanism, when switching between the first closing state and the second closing state, only one drive component is needed, which can effectively reduce production costs and facilitate the miniaturization of the switch. Furthermore, due to the structural arrangement of the first guide hole, the electromagnetic mechanism of the drive component magnetically attracts the moving iron core, causing the moving iron core to pull the transmission component to achieve the switching of the closing state. This reduces technical difficulty, simplifies product structure, simplifies assembly process, and improves reliability. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0079] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0080] like Figure 1 and Figure 2 As shown, this embodiment provides an operating mechanism for an automatic transfer switch, which can realize bidirectional movement of the operating mechanism with only one drive component 1. It has high reliability, low cost, small space occupation, and simplifies the assembly process.

[0081] Specifically, see Figure 1 and Figure 2 The automatic transfer switch includes a housing 100 for mounting the operating mechanism. The operating mechanism includes a drive assembly 1, a transmission assembly 2, a rotating shaft assembly 3, and a bracket 5. The drive assembly 1, located within the housing 100, specifically includes a cooperating electromagnetic mechanism 11 and a moving iron core 12. The electromagnetic mechanism 11, specifically an electromagnet, drives the moving iron core 12 to move under magnetic attraction when energized. One end of the moving iron core 12 extends out of the electromagnetic mechanism 11. The first end of the transmission assembly 2 is connected to the end of the moving iron core 12 extending from the electromagnetic mechanism 11, and moves under the drive of the moving iron core 12 of the drive assembly 1. The rotating shaft assembly 3 is rotatably connected to the housing 100 and movably connected to the second end of the transmission assembly 2. The rotating shaft assembly 3 has a first closed position and a second closed position relative to the housing 100, meaning it can reciprocate between these positions to switch the operating state of the automatic transfer switch.

[0082] The bracket 5 is mounted on the housing 100 and has a first guide hole 51. The transmission assembly 2 is slidably inserted through the first guide hole 51. The first guide hole 51 has an intermediate reversing position, which is located between the first end and the second end of the first guide hole 51 and is further away from the drive assembly 1 than the first end and the second end of the first guide hole 51. The moving iron core 12 is used to pull the transmission assembly 2 from the intermediate reversing position to the first end or the second end of the first guide hole 51 under the action of the electromagnetic mechanism 11, and drive the rotating shaft assembly 3 to rotate toward the first closed position or the second closed position.

[0083] By providing a first guide hole 51 on the bracket 5, and making the middle reversing position of the first guide hole 51 farther away from the drive assembly 1 than its first and second ends, an opening facing the drive assembly 1 can be formed between the first and second ends of the first guide hole 51. When the electromagnetic mechanism 11 has not yet generated a magnetic force on the moving iron core 12, the transmission assembly 2 is located in the middle reversing position. When the rotating shaft assembly 3 needs to switch positions, the electromagnetic mechanism 11 generates a magnetic attraction force on the moving iron core 12, causing the moving iron core 12 to pull the transmission assembly 2 from the middle reversing position towards the first or second end of the first guide hole 51 under the magnetic attraction force of the electromagnetic mechanism 11, and driving the rotating shaft assembly 3 to rotate towards the first or second closing position, thereby realizing the position switching and thus enabling the automatic transfer switch to switch working states. This operating mechanism only requires one drive assembly 1, and the bidirectional movement of the operating mechanism can be achieved by making the transmission assembly 2 move in both directions. It has high reliability, low cost, small space occupation, and simplifies the assembly process.

[0084] Because the intermediate reversing position is farther away from the drive assembly 1 than the first and second ends of the first guide hole 51, the transmission assembly 2 is subjected to the pulling force of the moving iron core 12 when it moves towards the two ends of the first guide hole 51, rather than the pushing force of the moving iron core 12. Compared with the method of using the electromagnetic mechanism 11 to repel the moving iron core 12 and push the transmission assembly 2 further away, the method of using the electromagnetic mechanism 11 to magnetically attract the moving iron core 12 and use the moving iron core 12 to provide the pulling force to move the transmission assembly 2, thereby realizing the switching between the first closing position and the second closing position, is easier to implement technically and simpler in structure. It can effectively reduce the assembly and coordination difficulty of the electromagnetic mechanism 11 and the moving iron core 12, reduce production costs and improve production efficiency. Moreover, the scheme of using the moving iron core 12 to provide the pulling force to realize the switching of the closing position has higher reliability and a relatively lower failure rate in switch products, thereby improving the overall competitiveness of the product.

[0085] In some embodiments, the first guide hole 51 extends in an arc shape and opens toward the drive assembly 1, so that the moving iron core 12 can pull the transmission assembly 2 by pulling force only.

[0086] In some other embodiments, the first guide hole 51 extends in a V-shape or a U-shape, and the opening of the first guide hole 51 extending in a V-shape or a U-shape faces the drive assembly 1, so that the moving iron core 12 can pull the transmission assembly 2 only by pulling force.

[0087] It is understandable that the middle reversing position of the first guide hole 51 is the position furthest away from the drive component 1.

[0088] For example, the first closing position is the normal closing position, and the second closing position is the standby closing position. The automatic transfer switch is used to automatically switch between the main power supply and the standby power supply to ensure power supply continuity. When a main power supply fault is detected (such as power outage, abnormal voltage, etc.), it can quickly disconnect the main power supply circuit and connect the standby power supply. The rotating shaft assembly 3 is connected to the contact system. When the rotating shaft assembly 3 is in the first closing position, the automatic transfer switch is in the first closing state of connecting the main power supply, and the normal contact of the contact system is closed. When the rotating shaft assembly 3 is in the second closing position, the automatic transfer switch is in the second closing state of connecting the standby power supply, and the standby contact of the contact system is closed.

[0089] Combination Figure 3 and Figure 4 The operating mechanism also includes a reversing assembly 4. The reversing assembly 4 is connected to the rotating shaft assembly 3 and can move under the drive of the rotating shaft assembly 3. When the rotating shaft assembly 3 is in the first closed position, the reversing assembly 4 stops on one side of the transmission assembly 2 along the first direction; when the rotating shaft assembly 3 is in the second closed position, the reversing assembly 4 stops on one side of the transmission assembly 2 along the second direction. The first direction is the direction in which the rotating shaft assembly 3 rotates towards the first closed position, and the second direction is the direction in which the rotating shaft assembly 3 rotates towards the second closed position. That is, the transmission assembly 2 is used to drive the rotating shaft assembly 3 to rotate in the first direction towards the first closed position or to drive the rotating shaft assembly 3 to rotate in the second direction towards the second closed position under the drive of the drive assembly 1; the first direction and the second direction are opposite.

[0090] The operating mechanism of the automatic transfer switch provided in this embodiment, when the rotating shaft assembly 3 is in the first closed position, the reversing assembly 4 stops at one side of the transmission assembly 2 along the first direction. When the drive assembly 1 is activated, it drives the rotating shaft assembly 3 to rotate through the transmission assembly 2. At this time, due to the stopping effect of the reversing assembly 4, the transmission assembly 2 cannot drive the rotating shaft assembly 3 to rotate along the first direction, but can only rotate along the second direction towards the second closed position, so that the rotating shaft assembly 3 can be smoothly switched to the second closed position. When the rotating shaft assembly 3 is in the second closed position, the reversing assembly 4 moves to the position where it stops at one side of the transmission assembly 2 along the second direction under the drive of the rotating shaft assembly 3. At this time, when the drive assembly 1 is activated, it drives the rotating shaft assembly 3 to rotate through the transmission assembly 2. Due to the stopping effect of the reversing assembly 4, the transmission assembly 2 cannot drive the rotating shaft assembly 3 to rotate along the second direction, but can only rotate along the first direction towards the first closed position, so that the rotating shaft assembly 3 can be smoothly switched to the first closed position. In this operating mechanism, by setting a reversing component 4 and using the stopping effect of the reversing component 4, the transmission component 2 can drive the rotating shaft component 3 to rotate in different directions in the first closing position and the second closing position, so as to realize the switching between the first closing position and the second closing position. Moreover, by setting the reversing component 4, the operating mechanism only needs one drive component 1 to realize the bidirectional movement of the operating mechanism, which has high reliability, low cost, small space occupation, and simplifies the assembly process.

[0091] See Figure 3 and Figure 4 The rotating shaft assembly 3 is provided with a first mating part 311 and a second mating part 312. The second end of the transmission assembly 2 is movable relative to the rotating shaft assembly 3 between the first mating part 311 and the second mating part 312, and the transmission assembly 2 is detachably abutted against the first mating part 311 and the second mating part 312 respectively. When abutting, it can drive the rotating shaft assembly 3 to rotate towards two closing positions respectively through the cooperation with the first mating part 311 and the second mating part 312. For example, after the transmission assembly 2 moves to abut against the first mating part 311, it drives the rotating shaft assembly 3 to rotate towards the second closing position in the second direction; after the transmission assembly 2 moves to abut against the second mating part 312, it drives the rotating shaft assembly 3 to rotate towards the first closing position in the first direction.

[0092] Specifically, Figure 3 The diagram shown is of the rotating shaft assembly 3 in the first closed position. Figure 4 This diagram shows the shaft assembly 3 in the second closed position. It should be noted that... Figure 3 and Figure 4The dashed line structure represents a schematic diagram of the second end of the transmission assembly 2 in both closing positions. When the shaft assembly 3 is in the first closing position, the reversing assembly 4 stops between the second mating part 312 and the second end of the transmission assembly 2. Therefore, due to the stopping effect of the reversing assembly 4, the transmission assembly 2 cannot pass over the reversing assembly 4 to engage with the second mating part 312. It can only move to the position of the first mating part 311 under the drive of the drive assembly 1, and drive the shaft assembly 3 to rotate towards the second closing position by abutting against the first mating part 311. When the shaft assembly 3 is in the second closing position, the reversing assembly 4 stops between the first mating part 311 and the transmission assembly 2. Therefore, due to the stopping effect of the reversing assembly 4, the transmission assembly 2 cannot pass over the reversing assembly 4 to engage with the first mating part 311. It can only move to the position of the second mating part 312 under the drive of the drive assembly 1, and drive the shaft assembly 3 to rotate towards the first closing position by abutting against the second mating part 312.

[0093] like Figure 1 and Figure 2 As shown, the transmission assembly 2 includes a first connecting rod 21 and a transmission shaft 22. The two ends of the first connecting rod 21 are rotatably connected to one end of the moving iron core 12 extending from the electromagnetic mechanism 11 and the transmission shaft 22, respectively. In this embodiment, the first guide hole 51 extends in an arc shape with the rotation axis of the rotating shaft assembly 3 as its center. The end of the transmission shaft 22 away from the first connecting rod 21 is the second end of the transmission assembly 2, which is slidably fitted into the first guide hole 51 and separably abuts against the first mating part 311 and the second mating part 312 on the rotating shaft assembly 3. When the rotating shaft assembly 3 is in the first closed position and the second closed position, the reversing assembly 4 is used to stop the transmission shaft 22, so that the transmission shaft 22 can only move to the position of the first mating part 311 or the position of the second mating part 312.

[0094] The moving iron core 12, the first connecting rod 21, the transmission shaft 22 and the bracket 5 constitute a four-bar linkage mechanism. When the moving iron core 12 moves under the drive of the electromagnetic mechanism 11, it can pull the first connecting rod 21 to move. The first connecting rod 21 then drives the transmission shaft 22 to slide along the first guide hole 51 and abut against the first mating part 311 or the second mating part 312, so that the transmission is stable and reliable.

[0095] See Figure 3 and Figure 4The rotating shaft assembly 3 is provided with a second guide hole 31, which extends in an arc shape around the rotation axis of the rotating shaft assembly 3. The drive shaft 22 is slidably engaged with the second guide hole 31. The first mating part 311 and the second mating part 312 are the hole walls at both ends of the second guide hole 31, respectively. Specifically, the drive shaft 22 is approximately perpendicular to the first connecting rod 21, passes through the first guide hole 51 and extends into the second guide hole 31, and is slidably engaged with both the first guide hole 51 and the second guide hole 31. When the drive shaft 22 slides within the second guide hole 31 under the drive of the first connecting rod 21, it can slide to abut against the hole wall at the first end of the second guide hole 31 (i.e., the first mating part 311) or slide to abut against the hole wall at the second end of the second guide hole 31 (i.e., the second mating part 312).

[0096] See Figure 3 When the drive shaft 22 slides in the second direction within the second guide hole 31, it can abut against the first mating part 311; see also Figure 4 When the drive shaft 22 slides in the second guide hole 31 along the first direction, it can abut against the second mating part 312.

[0097] In this embodiment, see Figure 1 The transmission assembly 2 also includes a first elastic element 23. One end of the first elastic element 23 is connected to the bracket 5 or the housing 100, and the other end is connected to the transmission shaft 22. During the sliding of the transmission shaft 22 along the second guide hole 31, the first elastic element 23 can be elastically deformed. When the rotating shaft assembly 3 is in the first closed position and the second closed position, the first elastic element 23 is collinear with the first connecting rod 21 and has a first length, such as... Figure 10 and Figure 13 As shown, the drive shaft 22 is in its initial position, separated from both the first mating part 311 and the second mating part 312; Figure 3 and Figure 4 The position of the drive shaft 22, indicated by the dashed line, is the initial position, at which point there is a gap between the drive shaft 22 and both the first mating part 311 and the second mating part 312. When the drive shaft 22 moves to abut against the first mating part 311 and the second mating part 312, the first elastic member 23 is in a stretched state and has a second length; wherein the second length is greater than the first length.

[0098] That is, during the movement of the drive shaft 22 to abut against the first mating part 311 and the second mating part 312, the first elastic element 23 is stretched to store energy. When the drive shaft 22 continues to drive the rotating shaft assembly 3 to rotate towards the first or second closing position through the abutment action with the first mating part 311 and the second mating part 312, the first elastic element 23 continues to be stretched until the rotating shaft assembly 3 rotates to the corresponding closing position. At this time, the first elastic element 23 and the first connecting rod 21 are set at an angle. When the electromagnet is de-energized, the moving iron core 12 is no longer magnetically attracted, and the first elastic element 23 releases its elastic potential energy to pull the moving iron core 12 back to its original position through the drive shaft 22 and the first connecting rod 21 until the first elastic element 23 and the first connecting rod 21 are collinear. Under the elastic force of the first elastic element 23, the drive shaft 22 is stabilized in the initial position.

[0099] For example, the first elastic element 23 is a spring, one end of which is hooked to the bracket 5 and the other end is hooked to the drive shaft 22.

[0100] In some embodiments, such as Figure 7 and Figure 8 As shown, the bracket 5 is provided with a slot 52 communicating with the first guide hole 51. When the drive shaft 22 is in the initial position, it engages with the slot 52 and abuts against the groove wall of the slot 52 under the action of the first elastic member 23. When the electromagnet is de-energized, the drive shaft 22 can slide along the first guide hole 51 under the elastic force of the first elastic member 23 until it is engaged in the slot 52, so that the drive shaft 22 is stably held in the initial position and will not move arbitrarily. When the electromagnet is energized again, the drive shaft 22 can be driven by the moving iron core 12 to slide towards the first mating part 311 or the second mating part 312. That is, when the drive shaft 22 is in the position engaged with the slot 52, it is located in the middle reversing position of the first guide hole 51.

[0101] In this embodiment, the orthographic projection of the reversing component 4 on the plane where the rotating shaft component 3 is located can at least partially overlap with the second guide hole 31, so as to stop the transmission shaft 22 located in the second guide hole 31.

[0102] like Figure 1 and Figure 2 As shown, the bracket 5, which is fixedly connected to the housing 100, includes a cover plate. The cover plate is spaced apart from the bottom plate of the housing 100. The cover plate is supported on the bottom plate of the housing 100 by legs, and the legs are threaded to the housing 100 by screws or other fasteners. The rotating shaft assembly 3 is rotatably connected to the bottom plate of the housing 100. The cover plate of the bracket 5 covers the rotating shaft assembly 3. The reversing assembly 4 is located between the bracket 5 and the rotating shaft assembly 3. The moving iron core 12 and the first connecting rod 21 are located on the side of the cover plate facing away from the rotating shaft assembly 3. The drive shaft 22 passes through the first guide hole 51 and extends into the second guide hole 31.

[0103] Combination Figure 3 and Figure 4 The bracket 5 is provided with a first limiting part 53 and a second limiting part 54 at intervals on the side facing the rotating shaft assembly 3. The reversing assembly 4 is movably located between the first limiting part 53 and the second limiting part 54 and can be detachably abutted against the first limiting part 53 and the second limiting part 54.

[0104] Specifically, such as Figure 3 As shown, when the shaft assembly 3 is in the first closed position, the reversing assembly 4 abuts against the first limiting part 53, and at this time the reversing assembly 4 stops the transmission shaft 22 in the initial position by stopping it on the side opposite to the first limiting part 53. Figure 3 The structure shown by the dashed line is the drive shaft 22 in the initial position. At this time, since the reversing component 4 is in contact with the first limiting part 53 and cannot move, it can play a stable and reliable stopping role on the drive shaft 22, so that the drive shaft 22 can only slide along the second direction to the first mating part 311, thereby causing the rotating shaft assembly 3 to rotate toward the second closing position.

[0105] like Figure 4 As shown, when the shaft assembly 3 is in the second closed position, the reversing assembly 4 abuts against the second limiting part 54 and stops the transmission shaft 22 in the initial position by stopping it on the side opposite to the second limiting part 54. Figure 4 The structure shown by the dashed line is the drive shaft 22 in the initial position. At this time, since the reversing component 4 is in contact with the second limiting part 54 and cannot move, it can play a stable and reliable stopping role on the drive shaft 22, so that the drive shaft 22 can only slide along the first direction to the second mating part 312, thereby causing the rotating shaft assembly 3 to rotate toward the first closed position.

[0106] In this embodiment, see Figure 2 , Figure 3 as well as Figure 4 The reversing assembly 4 includes a reversing member 41 and a second elastic member 42. The reversing member 41 is coaxially rotatably connected to the shaft assembly 3, meaning that the reversing member 41 is rotatably connected to the shaft assembly 3 and has the same rotation axis as the shaft assembly 3. One end of the second elastic member 42 is connected to the shaft assembly 3, and the other end is connected to the first end of the reversing member 41. The second end of the reversing member 41 is used to stop the drive shaft 22 of the transmission assembly 2. The rotation center of the reversing member 41 is located between the first end and the second end of the reversing member 41. When the reversing member 41 rotates, its first end and the second end swing relative to the rotation center. Under the elastic force of the second elastic member 42, the reversing member 41 can be separated and abut against the first limiting part 53 or the second limiting part 54, thereby achieving the stopping effect on the drive shaft 22.

[0107] See Figure 3When the rotating shaft assembly 3 is in the first closed position, the second elastic element 42, the first end of the reversing element 41, and the rotation center of the reversing element 41 are in a non-collinear state. At this time, the reversing element 41 can abut against the first limiting part 53 under the elastic force of the second elastic element 42. During the process of driving the rotating shaft assembly 3 to rotate to the first closed position, the transmission shaft 22 abuts against the second mating part 312, such as... Figure 3 The drive shaft 22, shown by the solid line, reaches the first closed position. The first elastic element 23 releases its elastic potential energy to reset the drive shaft 22 to its initial position. During this process, the drive shaft 22 contacts and slides along the side of the reversing element 41 facing the first limiting part 53, passing the reversing element 41 and reaching the side of the reversing element 41 facing away from the first limiting part 53. Afterwards, due to the stop of the reversing element 41, the drive shaft 22 cannot move towards the position of the second mating part 312.

[0108] When the drive shaft 22 abuts against the first mating part 311 to drive the rotating shaft assembly 3 to rotate in the second direction toward the second closing position, the rotating shaft assembly 3 drives the reversing member 41 and the second elastic member 42 to rotate synchronously, so that the reversing member 41 separates from the first limiting part 53 and gradually approaches the second limiting part 54 until the reversing member 41 contacts the second limiting part 54. Then, as the rotating shaft assembly 3 rotates, the reversing member 41 is blocked by the second limiting part 54, causing the second elastic member 42 to be stretched and store energy. When the rotating shaft assembly 3 reaches the second closing position, the second elastic member 42, the first end of the reversing member 41, and the rotation center of the reversing member 41 are in a non-collinear state. Under the elastic force of the second elastic member 42, the reversing member 41 abuts against the second limiting part 54. Figure 4 The state shown.

[0109] During the process of driving the rotating shaft assembly 3 to rotate to the second closed position, the drive shaft 22 abuts against the first mating part 311, such as... Figure 4 The drive shaft 22, shown by the solid line, reaches the second closed position. The first elastic element 23 releases its elastic potential energy to reset the drive shaft 22 to its initial position. During this process, the drive shaft 22 contacts and slides along the side of the reversing element 41 facing the second limiting part 54, passing the reversing element 41 and reaching the side of the reversing element 41 facing away from the second limiting part 54. Afterwards, due to the stop of the reversing element 41, the drive shaft 22 cannot move towards the position of the first mating part 311.

[0110] See Figure 1 , Figure 2 and Figure 3The reversing component 41 is rotatably connected between the bracket 5 and the rotating shaft assembly 3 via the mounting shaft 43. A fixing post 32 is provided on the rotating shaft assembly 3, spaced apart from the rotation center of the rotating shaft assembly 3 and located on the side of the rotation center away from the second guide hole 31. One end of the second elastic element 42 is hooked onto the fixing post 32, and a hook hole is provided at the first end of the reversing component 41, with the other end of the second elastic element 42 hooked into the hook hole.

[0111] For example, the second elastic element 42 is a spring.

[0112] like Figure 3 and Figure 4 As shown, the second end of the reversing member 41 is provided with a first stop surface 411 facing away from the first limiting part 53 and a second stop surface 412 facing away from the second limiting part 54. The first stop surface 411 and the second stop surface 412 are connected at an included angle. The transmission assembly 2 can slide along one of the first stop surface 411 and the second stop surface 412 until it engages with the other stop surface. Specifically, the first stop surface 411 and the second stop surface 412 are connected at an included angle so that the second end of the reversing member 41 forms a sharp angle structure, which can guide the sliding of the transmission shaft 22. Figure 3 Taking the illustrated state as an example, when the drive shaft 22 moves towards its initial position under the elastic force of the first elastic member 23, the drive shaft 22 slides along the second stop surface 412. Since there is a gap between the reversing member 41 and the second limiting part 54, it can adaptably rotate in the direction of the second limiting part 54 under the sliding and pressing action of the drive shaft 22, without obstructing the drive shaft 22. This allows the drive shaft 22 to smoothly pass over the reversing member 41 and reach its initial position, and then, under the action of the first elastic member 23, it is engaged in the slot 52 on the bracket 5. At this time, the first stop surface 411 of the reversing member 41 stops between the drive shaft 22 and the second mating part 312.

[0113] Furthermore, a first limiting surface 413 and a second limiting surface 414 are respectively provided on opposite sides of the reversing member 41. The first limiting surface 413 is connected to the first stop surface 411, and the second limiting surface 414 is connected to the second stop surface 412. The first limiting surface 413 is used to detachably abut against the second limiting part 54, and the second limiting surface 414 is used to detachably abut against the first limiting part 53. Along the direction close to the first stop surface 411 and the second stop surface 412, the distance between the first limiting surface 413 and the second limiting surface 414 gradually decreases, so that the reversing member 41 is generally conical in shape and has a smoother shape. Moreover, this arrangement allows the limiting surfaces and the corresponding limiting parts to maintain a sufficient distance when not abutting, thus providing enough space for the reversing member 41 to adaptably rotate in the direction of the corresponding limiting part under the sliding compression action of the drive shaft 22.

[0114] like Figure 2As shown, in this embodiment, the operating mechanism further includes a retractable energy storage component 6, and the rotating shaft assembly 3 is provided with a connecting portion 33 spaced apart from its own rotation center; both ends of the energy storage component 6 are rotatably engaged with the housing 100 and the connecting portion 33, respectively; combined with Figure 3 , Figure 4 , Figure 9 as well as Figure 12 As shown, when the shaft assembly 3 is in the first closed position and the second closed position, the energy storage component 6 has a third length. The shaft assembly 3 also has an energy storage position located between the first closed position and the second closed position. When the shaft assembly 3 rotates between the first closed position and the second closed position, it must pass through the energy storage position. When the shaft assembly 3 is in the energy storage position, the rotation center of the shaft assembly 3 and the rotation centers of both ends of the energy storage component 6 are collinear, and the energy storage component 6 is in a compressed state and has a fourth length; wherein, the fourth length is less than the third length.

[0115] That is, when the rotating shaft assembly 3 rotates toward the first closing position or the second closing position, the energy storage component 6 is compressed from the third length to the fourth length, and then reset from the fourth length to the third length. Since the energy storage component 6 releases elastic potential energy after being compressed to the fourth length, the rotating shaft assembly 3 can be driven to quickly reach the first closing position or the second closing position under the elastic force of the energy storage component 6.

[0116] In this embodiment, the energy storage component 6 in the first closing position and the second closing position is symmetrical to the energy storage component 6 in the energy storage position, and the rotating shaft component 3 in the first closing position and the second closing position is symmetrical to the rotating shaft component 3 in the energy storage position.

[0117] Specifically, such as Figure 6 As shown, the energy storage component 6 includes a second link 61, a third link 62, and a third elastic member 63. The second link 61 is rotatably engaged with the housing 100, and the third link 62 is rotatably engaged with the connecting part 33. The third elastic member 63 is sleeved on the second link 61 and the third link 62. Both the second link 61 and the third link 62 are provided with a stop block 611 that abuts against the third elastic member 63. The compression limit of the third elastic member 63 is located between the stop blocks 611 of the second link 61 and the third link 62, so that the second link 61 and the third link 62 can move towards each other and away from each other.

[0118] Furthermore, combined Figure 6 and Figure 9The inner wall of the housing 100 is recessed with a rotating groove. The second connecting rod 61 is rotatably abutted against the rotating groove under the elastic force of the third elastic member 63. The third connecting rod 62 is rotatably connected to the connecting part 33 via a rotating shaft. The second connecting rod 61 and the third connecting rod 62 are arranged crosswise, and corresponding insertion ports 612 are provided on both of them, so that the second connecting rod 61 and the third connecting rod 62 can be inserted into each other through the insertion ports 612, so that they can avoid each other when moving towards each other, and at the same time increase the degree of compression of the energy storage component 6.

[0119] like Figure 2 and Figure 5 As shown, the operating mechanism also includes an operating handle 7. The operating handle 7 includes a rotating part 71 and an operating lever 72 disposed on the rotating part 71. The rotating part 71 is rotatably connected to the housing 100, and the operating lever 72 extends at least partially out of the housing 100. The rotating shaft assembly 3 and the rotating part 71 are geared together. Specifically, the rotating shaft assembly 3 is provided with a first gear 34, and the rotating part 71 of the operating handle 7 is provided with a second gear 711 that meshes with the first gear 34. When either the rotating shaft assembly 3 or the operating handle 7 rotates, the other can rotate synchronously through the meshing action between the first gear 34 and the second gear 711. The portion of the operating lever 72 extending out of the housing 100 provides an indicator for the operator, indicating whether the automatic transfer switch is currently in the first closed position or the second closed position.

[0120] This embodiment also provides an automatic transfer switch, including a housing 100 and an operating mechanism for the automatic transfer switch as described above, the operating mechanism being disposed in the housing 100.

[0121] Because this automatic transfer switch includes the aforementioned operating mechanism, it exhibits high reliability when switching between the first and second closing states. Furthermore, the requirement of only one drive mechanism effectively reduces production costs and simplifies assembly processes, facilitating miniaturization of the switch. Moreover, the structural design of the first guide hole 51 allows the electromagnetic mechanism 11 of the drive assembly 1 to magnetically attract the moving iron core 12, which in turn pulls the transmission assembly 2 to achieve the closing state switching. This reduces technical complexity, simplifies product structure, streamlines assembly processes, and improves reliability.

[0122] The working process of the automatic transfer switch operating mechanism provided in this embodiment is roughly as follows:

[0123] 1) Electric switching process:

[0124] like Figure 10 As shown, the automatic transfer switch is in the first closed state, the rotating shaft assembly 3 is in the first closed position, the drive shaft 22 is locked in the slot 52 under the pulling force of the first elastic member 23, and the first connecting rod 21 is collinear with the first elastic member 23. The reversing member 41 of the reversing assembly 4 is stopped between the drive shaft 22 and the second mating part 312.

[0125] When the electromagnetic mechanism 11 is energized, the moving iron core 12 is pulled back into the electromagnetic mechanism 11. Simultaneously, the first connecting rod 21 drives the transmission shaft 22 to slide along the first guide hole 51 and the second guide hole 31, stretching the first elastic element 23. At this time, due to the blocking effect of the reversing element 41, the transmission shaft 22 can only slide towards the first mating part 311 in the second direction. When it abuts against the first mating part 311, it drives the rotating shaft assembly 3 to rotate in the second direction. During this process, the rotating shaft assembly 3 compresses the energy storage component 6. After the rotating shaft assembly 3 passes the energy storage position, the energy storage component 6 releases its elastic potential energy to drive the rotating shaft assembly 3 to quickly reach the second closing position. Figure 11 and Figure 12 As shown, at this instant, the drive shaft 22 is still in contact with the first mating part 311. Then, the electromagnetic mechanism 11 is de-energized, and under the elastic force of the first elastic element 23, the drive shaft 22 moves along the first direction until it is engaged in the slot 52 on the bracket 5, and is in a position as shown. Figure 13 The state shown.

[0126] When Figure 13 When the electromagnetic mechanism 11 in the second closed state is energized, it drives the transmission shaft 22 to move through the moving iron core 12 and stretches the first elastic member 23. At this time, due to the blocking effect of the reversing member 41, the transmission shaft 22 can only slide along the first direction toward the second mating part 312. When it comes into contact with the second mating part 312, it drives the rotating shaft assembly 3 to rotate along the first direction toward the first closed position. Similarly, in the latter half of the movement of the rotating shaft assembly 3, the energy storage component 6 releases potential energy to drive the rotating shaft assembly 3 to quickly reach the first closed position, such as... Figure 8 and Figure 9 As shown, at this instant, the drive shaft 22 is still in contact with the second mating part 312. Afterwards, the electromagnetic mechanism 11 is de-energized, and under the elastic force of the first elastic element 23, the drive shaft 22 moves along the second direction until it is engaged in the slot 52 on the bracket 5, and is in a position as shown. Figure 10 The state shown.

[0127] During the rotation of the shaft assembly 3, the operating handle 7 is driven to switch positions synchronously through gear engagement, and under the action of the energy storage component 6, the shaft assembly 3 can be stably maintained in the first closing position or the second closing position.

[0128] 2) Manual switching process:

[0129] For example Figure 10 and Figure 13The automatic transfer switch shown, in both closed states, rotates the operating handle 7 to drive the rotating shaft assembly 3 to rotate. The rotating shaft assembly 3 drives the reversing assembly 4 to move, causing the reversing member 41 to change direction, switching it from a position abutting one of the first limiting part 53 and the second limiting part 54 to a position abutting the other, so that the reversing member 41 can stop on the corresponding side of the drive shaft 22. During the rotation of the rotating shaft assembly 3, the energy storage assembly 6 is compressed. After the rotating shaft assembly 3 passes the energy storage position, the energy storage assembly 6 releases potential energy to drive the rotating shaft assembly 3 to rotate rapidly to the first closed position or the second closed position, and can stably maintain the first closed position or the second closed position under the action of the energy storage assembly 6.
