[0002] Patent CN201910772202.0 discloses a grounding switch operating cabinet provided with an electric operating device, including a cabinet body. An earthing switch and an earthing operating shaft are arranged in the cabinet body. One end of the earthing operating shaft is arranged in the cabinet body and connected to the earthing switch for controlling the earthing switch to close or separate. The other end is provided with an operating part for manual operation. An electric operating device is arranged on the earthing operating shaft. The electric operating device includes a driving element, a transmission mechanism and a clutch mechanism. The clutch mechanism has a first state in which the driving element drives the earthing operating shaft to act through the transmission mechanism when closed, and a second state in which the driving element cannot drive the earthing operating shaft when separated during manual operation.

When the clutch member swings to both ends of the placement groove respectively, the distance from the pointed tip near the middle of the placement groove to the center of the output member is greater than the distance from the pointed tip near the end of the placement groove to the center of the output member.

Detailed implementation manners

[0041] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] It should be noted that all the expressions using "first" and "second" in the embodiments of the present invention are used to distinguish two entities or parameters with the same name but different, so "first" and "second" are only for the convenience of expression and should not be construed as a limitation on the embodiments of the present invention. This will not be elaborated one by one in the subsequent embodiments.

[0043] The terms of direction and position mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only with reference to the direction or position of the accompanying drawings. Therefore, the terms of direction and position used are for explaining and understanding the present invention, rather than a limitation on the protection scope of the present invention.

[0044] Such as Figure 1 , an electric operating device includes an electric drive element 3, a mechanism box 6 and an automatic in-place mechanical clutch device. The electric drive element 3 is installed outside the mechanism box 6, and the automatic in-place mechanical clutch device is installed inside the mechanism box 6.

[0045] Such as Figure 2 shown, the automatic in-place mechanical clutch device includes an output member 1, an input wheel 2, a clutch member 4, and an in-place action ring 5.

[0046] Among them, the structure of the output member 1 is as Figure 3As shown, it has a rotating shaft perforation 103 at the center. A through hole is provided on the mechanism box 6 corresponding to the rotating shaft perforation 103 for the operating rotating shaft to pass through to form a circumferential linkage. When the output member 1 rotates, it directly drives the cooperating operating rotating shaft to rotate for opening and closing. It has an opening position and a closing position, and an installation groove 101 is provided on its outer periphery; the structure of the input wheel 2 is as Figure 4 shown. Its outer periphery is a turbine structure and meshes with a worm 7 connected to the output shaft of the electric drive element 3 to form a transmission, enabling it to perform a closing rotation in the closing direction and a tripping rotation in the tripping direction when the electric drive element 3 operates. A mating ring 204 protrudes from one end of its inner periphery. Two first mating grooves 201 are formed on the inner periphery of the mating ring 204. The positions of the two first mating grooves 201 correspond to the positions of the installation groove 101 when the output member 1 is in the opening position and the closing position. The two ends of each first mating groove 201 are respectively a first engaging surface 202 in a planar shape and a first separating action surface 203 in a rounded corner structure; the first separating action surfaces 203 of the two first mating grooves 201 are located on the closer side; the structure of the clutch member 4 is as Figure 5 shown. It has a rectangular clutch body 401. Its two sides are second engaging surfaces 402 in a planar shape and the upper ends of both sides are pointed tips 403 in a rounded corner shape. A limiting block 405 is provided at the upper end of the back surface of the clutch body 401, and the upper end surface of the limiting block 405 is a third separating action surface 406 in a cylindrical surface shape.

[0047] As Figure 7As shown, the clutch member 4 is disposed within the placement groove 101 and is radially movable relative to the output member 1. It has a first position where the outer end extends into the first mating groove 201 to engage the output member 1 with the input wheel 2, and a second position where it slides inward to disengage the output member 1 from the input wheel 2. Additionally, there is a position between the first and second positions. An elastic member 9 is provided within the placement groove 101, and the elastic member 9 exerts a force on the clutch member 4 in the direction from the second position towards the first position, causing the clutch member 4 to maintain the first position under normal conditions. The first mating surface 202 cooperates with the second mating surface 402 of the clutch member 4 in the first position to form a one-way linkage between the input wheel 2 and the clutch member 4, enabling the one-way rotation of the input wheel 2 to drive the synchronous rotation of the output member 1. The first separating surface 203 cooperates with the tip 403 of the clutch member 4 in the first position to exert a force on the clutch member 4 in the direction towards the second position, such that the reverse one-way rotation of the output member 1 can drive the clutch member 4 to move to the second position, thereby disengaging from the input wheel 2 and rotating freely in the reverse direction without driving the input wheel 2, achieving the purpose of disengagement. At the same time, the placement groove 101 is of a fan-shaped structure, and the clutch member 4 can swing relative to the output member 1 by a certain angle within the placement groove 101. When the clutch member 4 swings to both ends of the placement groove 101 respectively, the distance from the tip 403 near the middle of the placement groove 101 to the center of the output member 1 is greater than the distance from the tip 403 near the end of the placement groove 101 to the center of the output member 1, forming the third position of the clutch member 4, as Figure 7 shown, one tip 403 of the clutch member 4 is located within the first mating groove 201 and the other tip 403 is located outside the first mating groove 201.

[0048] As Figure 6 shown, the in-place action ring 5 is integrally formed on the inner wall of the mechanism box 6. An arc-shaped second mating groove 501 is provided on the inner wall of the in-place action ring 5. As Figure 8 shown, the in-place action ring 5 is sleeved outside the output member 1. The input wheel 2 is adapted to the outer periphery of the in-place action ring 5 and is sleeved outside the in-place action ring 5. The mating ring 204 is located outside one axial end of the in-place action ring 5. The outer end of the clutch member 4 is simultaneously in contact with the inner periphery of the in-place action ring 5 and the inner periphery of the mating ring 204. Specifically, the clutch body 401 of the clutch member 4 is located within the mating ring 204, and the limiting block 405 of the clutch member 4 is located within the second mating groove 501. Second separating surfaces 502 are provided at both ends of the second mating groove 501, and the second separating surfaces 502 cooperate with the clutch member 4 in the first position to exert a force on the clutch member 4 in the first position in the direction towards the second position; Figure 7 In the structure shown, when the input wheel 2 and the output member 1 further rotate in the clockwise direction, when the second separating surface 502 cooperates with the third separating surface 406 of the clutch member 4 in the first position, the clutch member 4 is pressed down to move it to the third position.

[0049] While the two first engagement surfaces 202 cooperate with the two tips 403 respectively, the clutch member 4 swings left and right to both ends of the placement groove 101 in the placement groove 101. When the clutch member 4 swings to one end of the placement groove 101, the distances from the upper tips 403 on both sides of its two ends to the center of the output member 1 are different. As Figure 7 shown, when the clutch member 4 swings to the left end of the placement groove 101, the distance from the tip 403 at the upper end of the left end of the clutch member 4 to the center is less than the distance from the tip 403 at the upper end of the right end of the clutch member 4 to the center. When the second separation action surface 502 cooperates with the third separation action surface 406 of the clutch member 4 in the first position and presses the clutch member 4 down to the third position, the tip 403 at the upper end of the left end of the clutch member 4 enters the placement groove 101 and the tip 403 at the upper end of the right end of the clutch member 4 protrudes relative to the placement groove 101. Conversely, when the clutch member 4 swings to the right end of the placement groove 101, the distance from the tip 403 at the upper end of the right end of the clutch member 4 to the center is less than the distance from the tip 403 at the upper end of the left end of the clutch member 4 to the center.

[0050] Specifically, the first separation action surface 203 and the second separation action surface 502 are smooth curved surfaces to reduce resistance.

[0051] The operation process of the automatic positioning mechanical clutch device in this embodiment is as Figures 9 - 12 shown. Figure 9 Shown is the reverse approaching and positioning separation state. The clutch member 4 cooperates with the first fitting groove 201 at the left end of the input wheel 2. When the input wheel 2 drives the output member 1 to rotate clockwise, the third separation action surface 406 of the clutch member 4 abuts and cooperates with the second separation action surface 502 at the right end of the second fitting groove 501 to press the clutch member 4 to the third position. At this time, when the input wheel 2 rotates clockwise again, it cannot continue to drive the output member 1 to rotate, ensuring that the output member 1 that has rotated in place cannot be further driven to rotate clockwise by the input wheel 2; conversely, Figure 9 During the counterclockwise rotation of the input wheel 2 in , the upper right tip 403 of the clutch member 4 acts on the first separation action surface 203 of the first fitting groove 201 at the left end of the input wheel 2, so that the outer end of the clutch member 4 can leave the first fitting groove 201 at the left end of the input wheel 2 to the second position until it enters the first fitting groove 201 at the right end of the input wheel 2 and rotates to Figure 10 shown in the reverse positioning and ready-to-engage state. Figure 10 When the input wheel 2 shown in rotates counterclockwise again, the first engagement surface 202 of the first fitting groove 201 at the right end of the input wheel 2 cooperates with the right side surface of the clutch member 4, and can drive the clutch member 4 and the output member 1 to rotate counterclockwise to Figure 11In the forward approaching, in-place and separating state position shown, when the input wheel 2 drives the output member 1 to rotate counterclockwise, the third separating surface 406 of the clutch member 4 abuts and cooperates with the second separating surface 502 at the left end of the second mating groove 501 to press down the clutch member 4 to the third position. At this time Figure 11 when the input wheel 2 in Figure 11 rotates counterclockwise again, it cannot continue to drive the output member 1 to rotate, ensuring that the output member 1 that has rotated in place cannot be further driven by the input wheel 2 to rotate counterclockwise; conversely, Figure 12 when the input wheel 2 in Figure 9 rotates clockwise, the left upper tip 403 of the clutch member 4 acts on the first separating surface 203 of the first mating groove 201 at the right end of the input wheel 2, so that the outer end of the clutch member 4 can leave the first mating groove 201 at the right end of the input wheel 2 to the second position until it enters the first mating groove 201 at the left end of the input wheel 2 and rotates to

[0052] the forward in-place and ready-to-engage state shown in

[0053] As Figure 7 、 Figure 8 shown, the elastic member 9 is a compression spring. A limit post 102 cooperating with the elastic member 9 is provided at the bottom of the placement groove 101, and a limit groove 404 cooperating with the elastic member 9 is provided at the bottom of the clutch member 4.

[0054] The in-place action ring 5 is integrally formed with the mechanism box 6, so that the output member 1, the input wheel 2, and the clutch member 4 are directly assembled into the mechanism box 6 through the in-place action ring 5, with a simple and compact structure and convenient assembly.

[0055] In this embodiment, a worm 7 is connected to the output shaft of the electric drive element 3. The outer circumference of the input wheel 2 is a turbine structure. The worm 7 is in meshing transmission cooperation with the input wheel 2. The two ends of the worm 7 are limited on the mechanism box 6, with a simple and compact structure and convenient assembly. A variable-speed gear transmission can also be adopted between the electric drive element 3 and the input wheel 2 according to needs.

[0056] Figure 13 Shown is a specific structure in which the electric operating device of this embodiment is applied to a grounding switch. The grounding rotating shaft 8 serves as an operating rotating shaft and extends into the rotating shaft through-hole 103 of the output member 1 for electric operation through the clutch device, and manual operation can also be performed.

[0057] The electric operating device of this embodiment can also cooperate with other switches that require manual and electric operation.

[0058] Those of ordinary skill in the art can understand that all or part of the steps in implementing the methods of the above embodiments can be completed by instructing relevant hardware through a program, and the program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, optical disc, etc.

[0059] The above-disclosed are only the preferred embodiments of the present invention, and of course, the scope of the rights of the present invention cannot be limited thereby. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
