[0072] Specifically, the switch device includes a moving contact (not shown), which rotates to have a normal closing position, a double opening position and a standby closing position, and the double opening position is located between the normal closing position and the standby closing position. In the normal closing position, the moving contact can be in contact with the static contact on the normal side to achieve the connection of the normal power circuit; in the standby closing position, the moving contact can be in contact with the static contact on the standby side to achieve the connection of the standby power circuit; in the double opening position, the moving contact is separated from the static contacts on both sides, so that the normal power circuit and the standby power circuit are disconnected. The switch device is a prior art, and its specific structure will not be described in detail in this application.

[0073] Specifically, the switch operating device includes a bracket 100, a transmission shaft 200, a transmission assembly 300, an operating assembly 400 and a reversing member 500. The transmission shaft 200 is connected to the bracket 100, and the transmission shaft 200 is used to connect the moving contact.

[0076] In this embodiment, the switching arrangement of the switching member 500 between the first gear and the second gear is used to guide the sliding member 310, so that the sliding member 310 can slide between the initial position and the first limit position or between the initial position and the second limit position, thereby realizing the switching of the moving contact between the common closing position and the double opening position, or the switching of the moving contact between the spare closing position and the double opening position. That is, when the switching member 500 is in the first gear, the moving contact cannot be switched to the spare closing position; when it is in the second gear, the moving contact cannot be switched to the common closing position, thereby making the moving contact reliably parked at the double opening position, which is safe and stable, and has a simple structure and is easy to operate. In addition, the switch operating device is composed of a bracket 100, a transmission shaft 200, a transmission assembly 300, an operating assembly 400 and a switching member 500, with fewer parts, which effectively improves the product assembly efficiency, reduces the product production cost, and reduces the product size.

In this embodiment, the reversing drive assembly 600 can be set to realize automatic switching of the reversing member 500 between the first gear and the second gear, thereby facilitating control.

[0106] Specifically, the reversing member 500 includes a first side surface 501 and a second side surface 502 that are set at an angle. In the first gear position, the first side surface 501 can guide the sliding member 310 to slide between the initial position and the first limit position; in the second gear position, the second side surface 502 can guide the sliding member 310 to slide between the initial position and the second limit position. The first side surface 501 and the second side surface 502 are rounded to prevent the sliding member 310 from being scratched. In this embodiment, Fig.11 As shown, in the first gear, when the sliding member 310 slides from the initial position to the first limit position, the sliding member 310 first slides under the guidance of the guide hole 321 until it contacts the first side surface 501, and then the sliding member 310 slides toward the second end of the first guide groove portion 1111 under the guidance of the first side surface 501, and finally the sliding member 310 contacts the side wall of the first guide groove portion 1111, and slides toward the second end of the first guide groove portion 1111 under the guidance of the side wall of the first guide groove portion 1111. In the second gear position, during the sliding process of the sliding member 310 from the initial position to the second limit position, the sliding member 310 first slides under the guidance of the guide hole 321 until it contacts the second side surface 502, and then the sliding member 310 slides toward the second end of the second guide groove portion 1112 under the guidance of the second side surface 502, and finally the sliding member 310 contacts the side wall of the second guide groove portion 1112, and slides toward the second end of the second guide groove portion 1112 under the guidance of the side wall of the second guide groove portion 1112.

[0107] For example, the switching member 500 is connected to the bracket 100 in a rotational or sliding manner, that is, the switching drive assembly 600 drives the switching member 500 to rotate or slide relative to the bracket 100, and the structure is simple and compact. Specifically, the switching member 500 is connected to the side plate portion 1102 of the mounting plate 110 in a rotational or sliding manner.

[0108] Exemplarily, the first end of the switching member 500 is provided with a first side surface 501 and a second side surface 502 , the middle section of the switching member 500 is rotatably connected to the side plate portion 1102 , and the second end of the switching member 500 is connected to the switching drive assembly 600 .

[0109] In a feasible implementation, a positioning member 510 is provided on the switching member 500, and a positioning hole 112 is provided on the bracket 100 for the positioning member 510 to pass through, and the switching member 500 is limited to the first gear position or the second gear position by the positioning member 510 abutting against the side wall of the positioning hole 112. Among them, the positioning hole 112 can be provided on the side plate portion 1102. For example, the positioning hole 112 can be a circular hole, and the positioning member 510 can include a cylindrical portion passing through the positioning hole 112, and the diameter of the positioning hole 112 is larger than the diameter of the cylindrical portion, so as to facilitate processing and assembly.

[0110] In this embodiment, continue to refer to Figure 1 , Figure 3 , Fig. 9 and Fig.10As shown, the reversing drive assembly 600 includes a second coil 610, a second moving iron core 620 and a second elastic member 630. The second coil 610 is arranged on the bracket 100; the second moving iron core 620 is penetrated by the second coil 610, the second moving iron core 620 is connected to the reversing member 500, and the second coil 610 obtains electrical energy to move the second moving iron core 620 toward the second coil 610; the second elastic member 630 is arranged between the second coil 610 and the second moving iron core 620, and the second elastic member 630 makes the sliding member 310 always have a tendency to move away from the second coil 610. For example, when the second coil 610 is powered, the second moving iron core 620 moves toward the second coil 610, thereby driving the commutator 500 to switch from the first gear to the second gear; when the second coil 610 is powered off, the second elastic member 630 moves the second moving iron core 620 away from the second coil 610, thereby driving the commutator 500 to switch from the second gear to the first gear, thereby realizing automatic control of the commutator 500 and effectively ensuring the compact structure of the switch operating device and reducing the product size. In addition, when the second coil 610 is powered off, under the action of the second elastic member 630, the commutator 500 remains in the first gear, and pressing the second end of the commutator 500 can move the second moving iron core 620 toward the second coil 610, so that the commutator 500 switches to the second gear, thereby realizing manual operation. In this embodiment, when the second coil 610 loses power, after the sliding member 310 slides out of the initial position, it first contacts the switching member 500, and the switching member 500 is squeezed by the sliding member 310 to move a certain distance or rotate a certain angle toward the second gear position, and the second elastic member 630 is deformed; when the sliding member 310 is separated from the switching member 500 and contacts the side plate of the first guide groove portion 1111, the switching member 500 returns to the first gear position under the action of the second elastic member 630. Therefore, without operating the second coil 610, the sliding member 310 can be directly switched to the first limit position through the operating assembly 400.

[0111] Exemplarily, the second coil 610 may be fixed on the bottom plate portion 1101 of the mounting plate 110 .

[0112] Exemplarily, the second end of the commutator 500 is connected to the second moving iron core 620. Specifically, a U-shaped frame 520 is provided at the second end of the commutator 500, and the second moving iron core 620 is located in the U-shaped frame 520. The commutation drive assembly 600 also includes a third connecting shaft, and the third connecting shaft is passed through the two side plates of the U-shaped frame 520 and the second moving iron core 620. Among them, the two side plates of the U-shaped frame 520 are respectively provided with a first through hole (not shown) for the third connecting shaft to pass through, and the end of the second moving iron core 620 is provided with a second through hole (not shown) for the third connecting shaft to pass through, and a gap is formed between at least one of the first through hole and the second through hole and the third connecting shaft to prevent jamming.

[0113] Exemplarily, the second elastic member 630 may be a spring. Specifically, a first stopper 621 is provided at the end of the second moving iron core 620, and the second elastic member 630 may be sleeved on the second moving iron core 620, and a first end of the second elastic member 630 abuts against the first stopper 621, and a second end of the second elastic member 630 abuts against the second coil 610.

[0114] In this embodiment, refer to Figure 1 , Figure 3 and Fig.12 As shown, the switch operating device further includes a locking member 700 disposed on the bracket 100, and the locking member 700 is movable relative to the bracket 100 and has an upper locking position and an unlocking position. In the upper locking position, the locking member 700 can be engaged with the operating component 400 to limit the sliding member 310 to the first limit position or the second limit position; in the unlocking position, the locking member 700 can be separated from the operating component 400. In this embodiment, the setting of the locking member 700 can effectively prevent the switch device from being disconnected, so as to ensure the continuous connection of the common power circuit or the backup power circuit.

[0115] It can be understood that when the locking member 700 is in the upper locking position and the first coil 420 is energized, the first moving iron core 430 can drive the sliding member 310 to slide from the initial position to the first limit position or the second limit position through the pull rod 410; when the first coil 420 is de-energized, the first elastic member 440 can drive the sliding member 310 to slide from the first limit position or the second limit position to the initial position.

[0116] Specifically, the locking member 700 can be engaged with the limiting shaft 460 in the upper locking position. Further specifically, the locking member 700 is located on the side of the support plate 150 facing away from the side plate portion 1102, and the locking member 700 can be engaged with one end of the limiting shaft 460 facing away from the side plate portion 1102, effectively ensuring the compactness of the structure of the switch operating device and reducing the product size.

[0117] In this embodiment, continue to refer to Figure 1 , Figure 3 and Fig.12 As shown, the lock member 700 is connected to a lock driving assembly 800, and the lock driving assembly 800 is used to drive the lock member 700 to switch between the upper locking position and the unlocking position, and can automatically control the switching of the lock member 700 between the upper locking position and the unlocking position.

[0118] Specifically, the lock driving assembly 800 includes a third coil 810, a third moving iron core 820 and a third elastic member 830. The third coil 810 is arranged on the bracket 100; the third moving iron core 820 is passed through the third coil 810, the third moving iron core 820 is connected to the lock member 700, and the third coil 810 obtains electrical energy to move the third moving iron core 820 toward the third coil 810; the third elastic member 830 is arranged between the third coil 810 and the third moving iron core 820, and the third elastic member 830 makes the sliding member 310 always have a tendency to move away from the third coil 810. Exemplarily, the third coil 810 is energized to move the third moving iron core 820 toward the third coil 810, thereby driving the lock member 700 to switch from the upper locking position to the unlocking position. The third coil 810 loses power, and the third elastic member 830 moves the third moving iron core 820 away from the third coil 810, thereby driving the lock member 700 to switch from the unlocking position to the upper locking position, thereby realizing automatic control of the lock member 700 and effectively ensuring the compact structure of the switch operating device and reducing the product size. In addition, when the third coil 810 loses power, under the action of the third elastic member 830, the lock member 700 remains in the upper locking position to prevent the sliding member 310 from moving and prevent the switch device from opening. Pressing the lock member 700 or the third moving iron core 820 can move the third moving iron core 820 toward the third coil 810 to switch the lock member 700 to the unlocking position, thereby realizing manual operation.

[0119] Exemplarily, the third coil 810 may be fixed on the bottom plate portion 1101 of the mounting plate 110 .

[0120] Specifically, the lock member 700 is stepped, including a first step groove 710 and a second step groove 720 arranged in sequence along the first direction. The first step groove 710 is closer to the first coil 420 along the first direction than the second step groove 720. In this embodiment, when the lock member 700 is in the unlocking position and the sliding member 310 is in the initial position, the limiting shaft 460 is placed in the second step groove 720, and the groove wall of the second step groove 720 is against the limiting shaft 460, so that the lock member 700 can be kept in the unlocking position. When the first armature moves toward the first coil 420, the limit shaft 460 moves from the second step groove 720 toward the first step groove 710. When the limit shaft 460 and the first step groove 710 are opposite to each other along the third direction, under the action of the third elastic member 830, the lock member 700 moves from the unlocking position to the locking position, and the limit shaft 460 is placed in the first step groove 710 to form a snap connection to prevent the limit shaft 460 from moving, thereby limiting the sliding member 310 to the first limit position or the second limit position. Figure 1 The c direction in the figure is the third direction, and the third direction may be the height direction of the bracket 100 .

[0121] Exemplarily, the third elastic member 830 may be a spring. Specifically, a second stopper is provided at the end of the third moving iron core 820, and the third elastic member 830 may be sleeved on the third moving iron core 820, and a first end of the third elastic member 830 abuts against the second stopper, and a second end of the third elastic member 830 abuts against the third coil 810.

[0122] In a feasible implementation, the support plate 150 is provided with a second elongated hole 152, and the locking member 700 is provided with a limiting portion 730, which is passed through the second elongated hole 152 to limit the movement of the locking member 700, effectively reduce the impact between the locking member 700 and the limiting shaft 460, and improve the service life of the switch operating device. Exemplarily, the limiting portion 730 can be formed by bending.

[0123] In this embodiment, refer to Figure 1 and Fig.12 As shown, the switch operating device also includes a micro switch 900 arranged on the bracket 100. The locking member 700 can trigger the micro switch 900 in the locked position or the unlocked position.

[0124] Exemplarily, the micro switch 900 is disposed on the support plate 150 and is located between the bottom plate 1101 and the locking member 700 along the third direction. In this embodiment, the locking member 700 triggers the micro switch 900 in the unlocking position, and the locking member 700 is separated from the micro switch 900 in the locking position.
