Switching device and operating method

Abstract

This invention discloses a switch actuator and its operating method, belonging to the technical field of power systems. The actuator employs a drive mechanism to move a toggle mechanism, which is at least partially located within a movable slot, with its width less than the width of the slot. The toggle mechanism abuts against the inner wall of the movable slot and has an open and closed position. In use, when the drive mechanism is in the first moving position, and the first trigger engages with the first sensing element, the toggle mechanism is in the closed position. Simultaneously, the first sensing element controls the drive mechanism to return to the second moving position, allowing the toggle mechanism to move towards the open position. The drive mechanism in the second moving position does not affect manual operation of the toggle mechanism, enabling operation of the toggle mechanism in both electric and manual modes.

Description

Technical Field

[0001] This invention belongs to the technical field of power systems, specifically relating to a switch execution device and its operation method. Background Technology

[0002] Electrical cabinets are generally equipped with switches. Existing switches are typically operated in either electric or manual mode. In electric mode, an actuator controls the opening and closing of the switch, but manual operation is not possible. In manual mode, the switch does not require an actuator, but an operator must be physically present on-site to operate it. Compared to electric mode, manual mode is less convenient and cannot provide timely management of the existing power system.

[0003] However, in electric mode, when a short circuit or fault occurs in the power system, the switch will be unable to switch between opening and closing; therefore, the existing actuators still have considerable room for improvement. Summary of the Invention

[0025] In the fourth moving position, the second end of the maintenance and protection mechanism is located inside the housing;

[0026] In the fifth moving position, the second end of the maintenance and protection mechanism is located outside the housing, and the actuating mechanism is moved from the closed position to the open position by the maintenance and protection mechanism.

When the locking ring is outside the housing, the first shielding plate is used to shield the first strip groove.

[0038] The present invention also proposes an operation method for a switch actuator, comprising the following steps:

[0039] Step 1: Start the drive mechanism. The drive mechanism moves from the second moving position to the first moving position to push the toggle mechanism from the open position to the closed position. The first trigger senses the first sensor, and the first sensor controls the drive mechanism to move from the first moving position to the second moving position.

[0040] Step 2: Start the drive mechanism. The drive mechanism moves from the second moving position to the third moving position to push the toggle mechanism from the closed position to the open position. The first trigger senses the second sensor, and the second sensor controls the drive mechanism to move from the third moving position to the second moving position.

[0041] The technical solution provided by this invention has the following advantages and effects:

[0042] A drive mechanism moves the actuating mechanism, which is at least partially located within a movable slot, with its width less than the slot's width. The actuating mechanism abuts against the inner wall of the slot and has both a disengaged and engaged position. In use, when the drive mechanism is in its first moving position, the actuating mechanism is engaged when the first trigger engages with the first sensor. Simultaneously, the first sensor controls the drive mechanism to return to its second moving position, allowing the actuating mechanism to move towards the disengaged direction. The second moving position does not impede manual operation of the actuating mechanism, enabling operation in both electric and manual modes. When the drive mechanism moves to its third moving position, the actuating mechanism is disengaged when the first trigger engages with the second sensor. Simultaneously, the second sensor controls the drive mechanism to return to its second moving position, allowing the actuating mechanism to move towards the engaged direction. The second moving position also does not impede manual operation of the actuating mechanism, enabling operation in both electric and manual modes. This switch actuator has both electric and manual modes, which are independent of each other. The "closed" position indicates that the switch is closed, and the "open" position indicates that the switch is open, thus enabling the switch to perform opening or closing operations. In this switch actuator, regardless of how the drive mechanism moves the toggle mechanism, it will eventually return to the second moving position, satisfying the requirement for manual operation. Furthermore, the first and second sensors respectively cooperate with the first trigger to identify the state and position of the toggle mechanism, thereby monitoring the switch status. Therefore, compared with existing electric switch actuators, this device has a significantly superior technological advantage. Attached Figure Description

[0066] To facilitate understanding of the present invention, specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings.

[0067] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0068] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0069] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0070] like Figures 1 to 7As shown, a switch actuator 100 includes: a housing 1, an actuator module 2, and a sensor 13 mounted on the housing 1. The sensor 13 includes a first sensing element 131 and a second sensing element 132. The actuator module 2 includes a toggle mechanism 30 and a drive mechanism 21. The drive mechanism 21 is electrically connected to the first sensing element 131 and the second sensing element 132, respectively. The drive mechanism 21 is movably disposed within the housing 1 and has a movable slot 251 for the toggle mechanism 30 to move. The toggle mechanism 30 is at least partially located in the movable slot. The actuating mechanism 30 is located within the slot 251, and its width is less than that of the movable slot 251. The actuating mechanism 30 has a first trigger 31, and the driving mechanism 21 has a first moving position, a second moving position, and a third moving position. At the first moving position, the first trigger 31 cooperates with the first sensor 131 to move the driving mechanism 21 from the first moving position to the second moving position. At the third moving position, the first trigger 31 cooperates with the second sensor 132 to move the driving mechanism 21 from the third moving position to the second moving position. A drive mechanism 21 is used to move the actuating mechanism 30. The actuating mechanism 30 is at least partially located within the movable groove 251, and the width of the actuating mechanism 30 is smaller than the width of the movable groove 251. The actuating mechanism 30 is used to abut against the inner wall of the movable groove 251. The actuating mechanism 30 has a split position and a closed position. In use, when the drive mechanism 21 is in the first moving position and the first trigger 31 cooperates with the first sensor 131, the actuating mechanism 30 is in the closed position. At the same time, the first sensor 131 will control the drive mechanism 21 to return to the second moving position. The actuating mechanism 30 can move towards the split position. The drive mechanism 21 in the second moving position does not affect the manual operation of the actuating mechanism 30, so that the actuating mechanism 30 can be operated in either electric or manual mode.

[0071] When the drive mechanism 21 moves to the third moving position, the first trigger 31 cooperates with the second sensor 132, and the toggle mechanism 30 is in the open position. At the same time, the second sensor 132 controls the drive mechanism 21 to return to the second moving position, and the toggle mechanism 30 can move towards the closed position. The drive mechanism 21 in the second moving position will not affect the manual operation of the toggle mechanism 30. The toggle mechanism can be operated in both electric and manual modes, realizing that the switch actuator 100 has both electric and manual modes. Moreover, the electric mode and the manual mode are independent of each other. The closed position indicates that the switch is closed, and the open position indicates that the switch is open, thereby enabling the switch to perform opening or closing operations. In this switch actuator 100, no matter how the drive mechanism 21 pushes the toggle mechanism 30 to move, it will eventually return to the second moving position, thus satisfying the manual operation of the switch actuator 100. Moreover, the first sensor 131 and the second sensor 132 respectively cooperate with the first trigger 31 to identify the state position of the toggle mechanism 30, thereby monitoring the switch state. Therefore, compared with the existing electric switch actuator 100, this device has a far superior technical effect.

[0072] In the second moving position, the drive mechanism 21 enables the actuating mechanism 30 to have a moving path toward the open or closed position. For example... Figure 1 and Figure 4 As shown, the drive mechanism 21 also has a second trigger 254, and the sensor 13 also has a third sensor 133. The third sensor 133 is electrically connected to the drive mechanism 21. In the second moving position, the second trigger 254 and the third sensor 133 are inductively engaged. When the second trigger 254 and the third sensor 133 are inductively engaged, the third sensor 133 will control the drive mechanism 21 to stop working, so that the drive mechanism 21 is stationary in the second moving position, preventing the drive mechanism 21 from moving back and forth between the first moving position and the third moving position. At this time, regardless of the position of the actuating mechanism 30 in the movable slot 251, it has a moving path toward the split or joined position. Specifically, the outer wall of the actuating mechanism 30 away from the split position contacts the inner wall of the movable groove 251, so the driving mechanism 21 cannot interfere with the actuating mechanism 30 moving toward the split position within the movable groove 251; and / or, the outer wall of the actuating mechanism 30 away from the closed position contacts the inner wall of the movable groove 251, so the driving mechanism 21 cannot interfere with the actuating mechanism 30 moving toward the closed position within the movable groove 251, thereby enabling the driving mechanism 21 to achieve a movement path of the actuating mechanism 30 toward either the split or closed position in the second moving position.

[0073] To further improve the sensing effect of the first trigger 31 with either the first sensor 131 or the second sensor 132, such as... Figure 1 and Figure 4As shown, the first moving position, the second moving position, and the third moving position are all in the first direction, and the second moving position is located between the first moving position and the third moving position. This simplifies the driving mechanism 21 by making the first moving position, the second moving position, and the third moving position all in the same direction. In implementing both electric and manual modes of the switch actuator 100, the structure of the switch actuator 100 is simplified as much as possible, making the switch actuator 100 more compact. The first trigger 31 includes a fourth sensing element 264 and a fifth sensing element 271. The fourth sensing element 264 is disposed facing the first sensing element 131, and the fifth sensing element 271 is disposed facing the second sensing element 132. In the first moving position, the fourth sensing element 264 and the first sensing element 131 are inductively engaged; in the third moving position, the fifth sensing element 271 and the second sensing element 132 are inductively engaged. By positioning the fourth sensor 264 closer to the first sensor 131 and the fifth sensor 271 closer to the second sensor 132, when the toggle mechanism 30 moves to the position of the first sensor 131, the fourth sensor 264 first engages with the first sensor 131, enhancing the sensing effect between the first trigger 31 and the first sensor 131. When the toggle mechanism 30 moves to the position of the second sensor 132, the fifth sensor 271 first engages with the second sensor 132, further enhancing the sensing effect between the first trigger 31 and the second sensor 132.

[0074] To further enable the first trigger 31 and the second trigger 254 to cooperate with the sensor 13, the following additional features are used: the first sensor 131 and the third sensor 133 are both infrared sensors, the second sensor 132 is a Hall sensor; the fourth sensor 264 and the second trigger 254 are both blocking blocks, the fifth sensor 271 is a magnet, and / or the first sensor 131 and the third sensor 133 are both blocking blocks, the fourth sensor 264 and the second trigger 254 are both infrared sensors; the second sensor 132 is a magnet, and the fifth sensor 271 is a Hall sensor. When the blocking block moves to the position of the first sensor 131 or the second sensor 132, the blocking block will block the light from the infrared sensor, thereby causing the infrared sensor to generate different electrical signals, thus controlling the movement direction and operating status of the drive mechanism 21. When the toggle mechanism 30 moves to the third moving position, the magnet and the Hall sensor generate a Hall effect, thereby generating an electrical signal. This electrical signal is used to control the drive mechanism 21 to move to the second moving position, and at the same time, it transmits the position status signal of the toggle mechanism 30, so that the switch actuator 100 monitors the status position of the toggle mechanism 30 in electric mode.

[0075] In this embodiment, when the switch moves from the closed position to the open position, the switch is driven by the toggle mechanism 30 to travel halfway. The switch will trip in advance. At this time, the switch moves from the closed position to the open position, and the switch will drive the toggle mechanism 30 to the open position. At this time, the magnet and the Hall element are sensed, thereby controlling the drive mechanism 21 to move to the second movement position in advance before reaching the third movement position, reducing the movement stroke of the drive mechanism 21 and saving the power consumption of the drive mechanism 21.

[0076] In this embodiment, the Hall sensor is mainly suitable for isolating and converting complex signals such as AC, DC, and pulse. Utilizing the Hall effect principle, the converted signal can be directly acquired and received by various acquisition devices such as AD converters, DSPs, PLCs, and secondary instruments. It features fast response time, wide current measurement range, high accuracy, strong overload capacity, good linearity, and strong anti-interference capability. Therefore, the Hall sensor is used to improve the stability of the switching actuator 100. In an infrared sensor, under normal conditions, the infrared sensor emits infrared signals to its surroundings. If there are obstacles (obstructions) nearby, the obstacles will reflect part of the infrared signal back to the sensor's receiving tube. After receiving the reflected signal, the infrared sensor generates a corresponding voltage signal. The output signal of the infrared sensor depends on the state of the returned infrared signal, i.e., the signal strength and reflection angle.

[0077] To enable the switch actuator 100 to further control the closing and opening of the switch. For example... Figures 1 to 4 As shown, the second moving position is the initial position of the drive mechanism 21. The toggle mechanism 30 is in the initial position and has an open state and an closed state. The toggle mechanism 30 is used to connect or clamp the switch (not shown in the figure). When the drive mechanism 21 is in the first moving position, the toggle mechanism 30 is in the closed state, and the toggle mechanism 30 drives the switch to close. When the drive mechanism 21 is in the third moving position, the toggle mechanism 30 is in the open state, and the toggle mechanism 30 drives the switch to open, thereby further controlling the closing and opening of the switch.

[0078] To enable the drive mechanism 21 to switch back and forth between the first moving position, the second moving position, and the third moving position. For example... Figures 3 to 6As shown, the drive mechanism 21 includes a drive member 211, a drive block 25, and a lead screw 212. The drive member 211 is installed inside the housing 1, and the lead screw 212 is installed on the output end of the drive member 211 and extends along a first direction. The drive block 25 is at least partially sleeved on the lead screw 212 and threadedly engaged with it. The housing 1 has a guide rail 24 that slides with the drive block 25. The drive member 211 rotates, causing the lead screw 212 to rotate. The drive block 25 has an internal thread, and the drive block 25 is threadedly engaged with the lead screw 212. Since the drive block 25 slides with the guide rail 24, the guide rail 24 restricts the direction of movement of the drive block 25. The drive block 25 cannot rotate with the lead screw 212. During the rotation of the lead screw 212, friction is generated between the drive block 25 and the lead screw 212, causing the drive block 25 to move back and forth when the lead screw 212 rotates. The drive unit 211 drives the lead screw 212 to rotate clockwise or counterclockwise, causing the lead screw 212 to move the drive block 25 from the first moving position to the second moving position or from the third moving position to the second moving position. The guide rail 24 makes the drive block 25 move stably in the first direction, thereby allowing the drive mechanism 21 to switch back and forth between the first moving position, the second moving position and the third moving position.

[0079] In this embodiment, the outer casing 1 also includes a first circuit board 14, on which the first sensor 131, the second sensor 132, and the third sensor 133 are mounted. The driving component 211 is a servo motor, and the terminals of the servo motor are located on the first circuit board 14, thereby enabling the first sensor 131, the second sensor 132, and the third sensor 133 to be electrically connected to the driving component 211. The outer casing 1 includes a housing 11 and a mounting base 12. The housing 11 is mounted on the mounting base 12, forming a mounting cavity between the housing 11 and the mounting base 12. The first circuit board 14 is mounted on the mounting base 12 and located within the mounting cavity. The guide rail 24 and the driving component 211 are also mounted on the mounting base 12 and located within the mounting cavity.

[0080] To further improve the structural compactness of the drive mechanism 21, such as... Figure 5 and Figure 6As shown, the drive block 25 includes a first moving block 255 and a second moving block 256. The first moving block 255 and the second moving block 256 are an integral structure. The second moving block 256 is disposed at the first end of the first moving block 255 and is sleeved on the lead screw 212 and threadedly engaged with the lead screw 212. The second moving block 256 is used to transmit power and change the transmission direction of power. A second trigger 254 is installed at the second end of the first moving block 255. The second trigger 254 is used to sense and cooperate with the third sensor 133. After the drive block 25 moves a certain distance, the second trigger 254 senses the third sensor 133, thereby controlling the drive member 211 to stop rotating, so that the drive block 25 is stationary at the second moving position. A movable groove 251 is disposed on the first moving block 255 and extends from the top of the first moving block 255 to the bottom of the first moving block 255. The movable groove 251 extends along a first direction. The movable slot 251 is set in the first movable block 255, so that during the movement of the first movable block 255, the inner wall of the first movable block 255 abuts against the outer wall of the actuating mechanism 30. In electric mode, it drives the actuating mechanism 30 to move from the open position to the closed position and from the closed position to the open position. Figure 5 and Figure 6 It can be seen that the first moving block 255 occupies a small space and drives the actuating mechanism 30 to move. It can also meet the sliding cooperation between the first moving block 255 and the guide rail 24, further improving the structural compactness of the drive mechanism 21.

[0081] To further restrict the movement direction of the drive block 25, such as Figure 5 and Figure 6 As shown, the guide rail 24 has a first guide groove 241 and a second guide groove 242, which are arranged opposite to each other and extend along a first direction. The bottom of the first moving block 255 has a first guide block 252 that slides with the first guide groove 241 and a second guide block 253 that slides with the second guide groove 242. By sliding the first guide block 252 with the first guide groove 241 and the second guide block 253 with the second guide groove 242, the guide rail 24 restricts the movement direction of the driving block 25, causing the driving block 25 to move along the first direction.

[0082] To further improve the sensing efficiency of the first sensor 131 and the second sensor 132, such as... Figure 5 and Figure 6As shown, the actuating mechanism 30 includes a handle assembly 26 and a moving assembly 27. One end of the handle assembly 26 passes through the movable slot 251 and is mounted on the moving assembly 27. The height direction of the handle assembly 26 intersects with the first direction. The fourth sensor 264 of the first trigger 31 is mounted on the handle assembly 26. By mounting the handle assembly 26 on the moving assembly 27, it is convenient for the handle assembly 26 to manually control the movement of the moving assembly 27, thereby realizing the opening or closing of the actuating mechanism 30. Since the height direction of the handle assembly 26 intersects with the first direction, the fourth sensor 264 can be mounted at any position in the height direction of the handle assembly 26. This allows the fourth sensor 264 and the first sensor 131 to be set on the same horizontal line, thereby improving the sensing efficiency of the fourth sensor 264 and the first sensor 131.

[0083] In addition, the guide rail 24 also has a third guide groove 243, which is located between the first guide groove 241 and the second guide groove 242. The moving component 27 is located at the bottom of the drive block 25, and the moving component 27 slides in cooperation with the third guide groove 243. The fifth sensor 271 of the first trigger 31 is disposed on the moving component 27. When the drive mechanism 21 is in the third moving position, the fifth sensor 271 is exposed relative to the drive block 25. The third guide groove 243 is used to limit the moving direction of the moving component 27 and improve the stability of the moving component 27 when it moves. The fifth sensor 271 is disposed on the moving component 27 and moves with the moving component 27. When the drive mechanism 21 is in the third moving position, the fifth sensor 271 is exposed relative to the drive block 25, which prevents the drive block 25 from blocking the fifth sensor 271 from sensing the second sensor 132 and improves the sensing efficiency between the fifth sensor 271 and the second sensor 132.

[0084] To facilitate the mounting of the switch actuator 100 above the switch and to control the switch. For example... Figure 2 and Figure 7As shown, the moving assembly 27 includes a moving plate 271, a first clamping rod 272, and a second clamping rod 273. A handle assembly 26 and a fifth sensor 271 are mounted on the top of the moving plate 271. The upper surface of the moving plate 271 has a mounting groove 274, in which the handle assembly 26 is mounted. The first clamping rod 272 is mounted on the bottom of the moving plate 271, and a clamping position 22 is formed between the first clamping rod 272 and the second clamping rod 273. The clamping position 22 is used to place the switch, so that the switch is located between the first clamping rod 272 and the second clamping rod 273. During the movement of the moving assembly 27, the switch will be moved, so that the switch can open or close. Moreover, this configuration allows the switch actuator 100 to be installed without interrupting the power supply to the switch. The switch and the switch actuator 100 have minimal or no structural connection, but the switch actuator 100 can be used to control the switch after startup. Therefore, the switch actuator 100 is easy to install, making it suitable for power system upgrades.

[0085] In addition, the handle assembly 26 includes a handle sleeve 261 and a handle rod 263. The handle sleeve 261 has a slot 262, and the handle rod 263 has a locking block 265. The handle sleeve 261 is fitted over the handle rod 263, and the slot 262 engages with the locking block 265. The handle sleeve 261 has multiple indentations on its outer surface. The handle sleeve 261 is made of insulating material to improve the safety of operating the handle assembly 26. The indentations are used to increase the friction with the fingers, making it easier to operate the handle assembly 26.

[0086] To facilitate the maintenance of the power system. For example... Figure 1 , Figure 9 and Figure 10As shown, the switch actuator 100 also includes a maintenance and protection mechanism 5, which is movably disposed within the housing 1. The first end of the maintenance and protection mechanism 5 is used to abut against the toggle mechanism 30, and the second end of the maintenance and protection mechanism 5 has a fourth moving position and a fifth moving position. In the fourth moving position, the second end of the maintenance and protection mechanism 5 is located inside the housing 1; in the fifth moving position, the second end of the maintenance and protection mechanism 5 is located outside the housing 1, and the toggle mechanism 30 is moved from the closed position to the open position by the maintenance and protection mechanism 5. In the fourth moving position, the maintenance and protection mechanism 5 is concealed within the housing 1 to prevent it from being exposed and to avoid being affected or damaged by the external environment. In the fifth moving position, the second end of the maintenance and protection mechanism 5 is located outside the housing 1, and the toggle mechanism 30 is moved from the closed position to the open position by the maintenance and protection mechanism 5. The power system is suitable for maintenance only when the toggle mechanism 30 is in the open position. Since the switch is in the open position when it is in the open position, the power system is in a safe state, which is suitable for operator maintenance and greatly improves the safety of the operator. When in use, it is only necessary to fix the second end of the maintenance protection mechanism 5 to the outside of the housing 1, so that the toggle mechanism 30 is in the open position and the corresponding switch is also in the open state.

[0087] To ensure that the maintenance and protection mechanism 5 can be quickly restored to its original state after repair. Figures 9 to 13 As shown, the maintenance and protection mechanism 5 includes a movable part 511, a push rod 513, a reset part 52, and a bracket 7. The bracket 7 has a second strip groove 71 for the actuation mechanism 30 to move. The first end of the movable part 511 is connected to the first end of the push rod 513 through a fixing pin 512. The second end of the movable part 511 has a locking ring 5111. The push rod 513 is movably installed in the bracket 7. The second end of the push rod 513 is used to abut against the actuation mechanism 30. When maintenance is required, the locking ring 5111 can be pulled out from the housing 1 using a tool. The moving part 511 moves the actuating mechanism 30 from the engaged position to the disengaged position via the push rod 513. The first end of the reset part 52 is mounted on the push rod 513, and the second end of the reset part 52 abuts against the inner wall of the bracket 7. When the locking ring 5111 is outside the outer shell 1, the reset part 52 is squeezed by the bracket 7 and the push rod 513. After maintenance is completed, the lock 55 is opened. Without external force on the locking ring 5111, the push rod 513 is driven to its original position by the reaction force of the reset part 52, which in turn drives the moving part 511 to quickly return to its original position, thereby moving the locking ring 5111 into the outer shell 1. At this time, the maintenance protection mechanism 5 returns to its original state, improving the convenience of the maintenance protection mechanism 5.

[0088] To stop the drive unit 211 from operating during maintenance and to protect the drive unit 211. For example... Figure 10As shown, the outer casing 1 has a switch 4, which is electrically connected to the drive mechanism 21. The moving part 511 has a push block 5112. When the locking ring 5111 is outside the outer casing 1, the push block 5112 abuts against the switch 4. After the push block 5112 abuts against the switch 4, the switch 4 sends an electrical signal to the drive part 211 of the drive mechanism 21, causing the drive part 211 to stop operating. When the locking ring 5111 is locked by the lock 55 (the padlock can only be inspected when the circuit is open), if someone accidentally issues a closing operation command, the switch actuator 100 will still perform the closing action. However, since the switch actuator 100 has been locked by the maintenance protection mechanism 5, the drive part 211 cannot rotate and can only continuously stall. Over time, this will cause damage to the drive part 211, rendering the entire switch actuator 100 ineffective. Therefore, a switch 4 is provided. When the locking ring 5111 moves out of the housing 1, the push block 5112 triggers the switch 4, the circuit is cut off, and the drive component 211 is disconnected, thus protecting the drive component 211. In this embodiment, the bracket 7 is installed inside the housing 1, and the bracket 7 has a second circuit board 6. The switch 4 is installed on the second circuit board 6 and is used to electrically connect with the drive component 211 to control the start or stop of the drive component 211.

[0089] To lock the locking ring 5111 in the state outside the housing 1. For example... Figure 18 As shown, the maintenance and protection mechanism 5 also has a lock 55, which cooperates with the locking ring 5111, and at least a portion of the lock 55 is used to abut against the outer wall of the housing 1. This lock 55 is used to lock the locking ring 5111, keeping the locking ring 5111 stable outside the housing 1 and preventing it from being pulled back into the housing 1 by the reaction force of the reset member 52, thereby locking the locking ring 5111 in the state outside the housing 1.

[0090] To prevent the moving part 511 from directly impacting the bracket 7 during reset. Figures 9 to 13 As shown, the reset component 52 is a spring, which is sleeved on the outside of the push rod 513, and the end of the spring near the moving component 511 abuts against the inner wall of the bracket 7; the maintenance protection mechanism 5 has an anti-collision pad 514, which is installed on the outer wall of the moving component 511 and away from the second end of the push rod 513. When the locking ring 5111 is located inside the housing 1, this anti-collision pad 514 is used to abut against the bracket 7. Since the moving component 511 is subjected to the force of the spring, when it moves from outside the housing 1 to inside the housing 1, the moving component 511 will gain acceleration. In order to avoid the push rod 513 from hitting the bracket 7, the anti-collision pad 514 can buffer the push rod 513 and prevent the push rod 513 from directly hitting the bracket 7. The anti-collision pad 514 is made of silicone rubber. The moving component 511 directly hits the anti-collision pad 514 instead of the fixed bracket 7, thus achieving the function of buffering or noise reduction.

[0091] To facilitate the movement of the locking ring 5111 outside the housing 1. For example... Figure 9 , Figure 11, Figure 12 as well as Figure 18 As shown, the maintenance and protection mechanism 5 also includes a pushing component 54. A first strip-shaped groove 15 is provided on the top of the housing 1, extending along a first direction. The first end of the pushing component 54 is located inside the housing 1 and mounted on the push rod 513. The second end of the pushing component 54 passes through the first strip-shaped groove 15 and extends outside the housing 1. Pushing the pushing component 54 at the top of the housing 1 moves it along the first strip-shaped groove 15, acting on the push rod 513. This causes the push rod 513 to move the locking ring 5111 of the moving member 511 outside the housing 1. This arrangement improves the convenience of removing the locking ring 5111.

[0092] To facilitate the installation of component 54. For example... Figures 13 to 15 As shown, the pushing assembly 54 includes a locking plate 541 and a pushing part 542. The maintenance and protection mechanism 5 also has an abutment plate 53. The first end of the abutment plate 53 is mounted on the second end of the push rod 513, and the second end of the abutment plate 53 is mounted on the locking plate 541 and abuts against the actuating mechanism 30. The top of the locking plate 541 is detachably connected to the pushing part 542. The push rod 513 is fixed to the locking plate 541 by the abutment plate 53. The abutment plate 53 abuts against the actuating mechanism 30, increasing the contact area between the push rod 513 and the actuating mechanism 30. The pushing part 542 pushes the abutment plate 53 to move the actuating mechanism 30 to the position and pushes the locking ring 5111 of the moving part 511 to the outside of the housing 1. The top of the locking plate 541 is detachably connected to the pushing part 542, making the installation and removal of the pushing part 542 and the locking plate 541 more convenient.

[0093] To improve the connection stability between the pusher 542 and the locking plate 541. For example... Figures 15 to 17 As shown, the pushing part 542 includes a protrusion 5423 and a latch 5424. At least a portion of the protrusion 5423 passes through the first strip groove 15 and is located outside the housing 1. The latch 5424 is installed on the bottom of the protrusion 5423. A mounting position 543 is formed between the upper end face of the latch 5424 and the bottom of the protrusion 5423. The engaging plate 541 is ridge-shaped and at least a portion of the engaging plate 541 is located within the mounting position 543, abutting against the latch 5424 and the protrusion 5423 respectively. By at least a portion of the engaging plate 541 being disposed on the mounting position 543 and abutting against the latch 5424 and the protrusion 5423 respectively, the latch 5424 and the protrusion 5423 lock the engaging plate 541 in place, thereby improving the connection stability between the pushing part 542 and the engaging plate 541. In this embodiment, the buckle 5424 can be made of an elastic material to facilitate the disassembly and installation of the locking plate 541; moreover, the protrusion 5423 at least partially passes through the first strip groove 15, making the protrusion 5423 exposed, improving the convenience of the finger to act on the pushing part 542, and facilitating the manual operation of the pushing part 542 to push the locking plate 541 to move.

[0094] In this embodiment, as Figure 16 As shown, the abutment plate 53 has a first connecting hole 531 and a second connecting hole 532. The first connecting hole 531 is used for one end of the push rod 513 to pass through, so that the abutment plate 53 is fixed to the push rod 513 by fasteners. The locking plate 541 includes a first connecting plate 5411, a second connecting plate 5412, and a ridge 5413. The first connecting plate 5411, the second connecting plate 5412, and the ridge 5413 are an integral structure. The first connecting plate 5411 and the second connecting plate 5412 are arranged perpendicularly. The first connecting plate 5411 abuts against the abutment plate 53, increasing the force-bearing area of ​​the abutment plate 53, making it easier for the locking plate 541 to apply force to the abutment plate 53, and also improving the structural compactness of the locking plate 541 and the abutment plate 53, reducing the space occupied by the pushing assembly 54. The first connecting plate 5411 has a third connecting hole 5414 corresponding to the second connecting hole 532. Both the second connecting hole 532 and the third connecting hole 5414 are for fasteners to pass through, so that the abutment plate 53 is fixed to the first connecting plate 5411. The ridge 5413 is used to engage with the mounting position 543.

[0095] To prevent dust or debris from falling into the casing 1. Figure 17 and Figure 18 As shown, the pushing part 542 also includes a first baffle plate 5421 and a second baffle plate 5422. When the engaging plate 541 is in the mounting position 543, a first locking position 544 is formed between the engaging plate 541 and the bottom of one side of the protrusion 5423, and a second locking position is formed between the engaging plate 541 and the bottom of the other side of the protrusion 5423. The first baffle plate 5421 is installed in the first locking position 544, and the second baffle plate 5422 is installed in the second locking position, which improves the compactness of the pushing assembly 54 structure and simultaneously ensures that the first baffle plate 5421 and the second baffle plate 5422 are locked together by the engaging plate 541 and the protrusion 5423. Furthermore, the first baffle plate 5421 and the second baffle plate 5422 are located on both sides of the protrusion 5423, and move back and forth with the protrusion 5423, so that no matter what position the protrusion 5423 is in, there is always a first baffle plate 5421 or a second baffle plate 5422 located in the first strip groove 15. The first baffle plate 5421 or the second baffle plate 5422 extends along the first direction. When the locking ring 5111 is inside the housing 1, the second baffle plate 5422 is used to block the first strip groove 15. When the switch actuator 100 is in the closed position, the second baffle plate 5422 prevents dust or debris from falling into the housing 1. When the locking ring 5111 is outside the housing 1, the first baffle plate 5421 is used to block the first strip groove 15. When the switch actuator 100 is in the open position, the first baffle plate 5421 prevents dust or debris from falling into the housing 1.

[0096] like Figure 1As shown, the present invention also proposes an operation method for a switch actuator 100, comprising the following steps:

[0097] Step 1: Start the drive mechanism 21. The drive mechanism 21 moves from the second moving position to the first moving position to push the toggle mechanism 30 from the open position to the closed position. The first trigger 31 senses the first sensor 131, and the first sensor 131 controls the drive mechanism 21 to move from the first moving position to the second moving position.

[0098] Step 2: Start the drive mechanism 21. The drive mechanism 21 moves from the second moving position to the third moving position to push the toggle mechanism 30 from the closed position to the open position. The first trigger 31 senses the second sensor 132, and the second sensor 132 controls the drive mechanism 21 to move from the third moving position to the second moving position.

[0099] Through the above operating method, after the toggle mechanism 30 is engaged, the drive mechanism 21 moves from the first moving position to the second moving position, providing space for manual operation of the toggle mechanism 30; after the toggle mechanism 30 is disengaged, the drive mechanism 21 moves from the third moving position to the second moving position, providing space for manual operation of the toggle mechanism 30. This achieves independence between manual and electric operation. No matter how the drive mechanism 21 pushes the toggle mechanism 30, it will eventually return to the second moving position, thus satisfying the requirement for manual operation of the switch actuator 100. Furthermore, the first sensor 131 and the second sensor 132 respectively cooperate with the first trigger 31 to identify the state position of the toggle mechanism 30, thereby monitoring the switch state.

[0100] The above embodiments are not an exhaustive list based on the present invention, and there may be many other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
