DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0019] The directions and positions mentioned in the present invention, such as up, down, front, back, left, right, inside, outside, top, bottom, side, etc., are only directions or positions with reference to the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but are not intended to limit the scope of protection of the present invention.

[0020] like Figure 1 An electric operating device includes an electric drive element 3, a mechanism box 6 and an automatic mechanical clutch device, wherein the electric drive element 3 is installed outside the mechanism box 6, and the automatic mechanical clutch device is installed inside the mechanism box 6.

[0021] like Figure 2 As shown, the automatic in-position mechanical clutch device includes an output member 1, an input wheel 2, a clutch member 4, and an in-position action ring 5.

[0022] Among them, the structure of the output element 1 is as follows Figure 3 As shown, the center of the output wheel 100 has a shaft through hole 103, and the mechanism box 6 has a through hole corresponding to the shaft through hole 103, for the operating shaft to pass through to form a circumferential linkage. When the output member 1 rotates, it directly drives the matched operating shaft to rotate to open and close the switch, and has an opening position and a closing position. The outer periphery of the output wheel 100 has a placement groove 101; the structure of the input wheel 2 is as shown in FIG. Figure 4As shown, its outer periphery is a turbine structure, which meshes with the worm 7 connected to the output shaft of the electric drive element 3 to form a transmission, so that it can perform a closing rotation in the closing direction and an opening rotation in the opening direction under the action of the electric drive element 3. One end of its inner periphery is convex to form a matching ring 204. Two first matching grooves 201 are formed on the inner periphery of the matching ring 204. The positions of the two first matching grooves 201 correspond to the positions of the placement grooves 101 when the output element 1 is in the opening position and the closing position. The two ends of the first matching groove 201 are respectively a first plane joint surface 202 and a first separation action surface 203 with a rounded structure; the first separation action surfaces 203 of the two first matching grooves 201 are located on the side close to each other; the structure of the clutch member 4 is as shown in FIG. Figure 5 As shown, a clutch body 401 is provided with a rectangular shape, and two sides thereof are planar second engaging surfaces 402 and two upper ends are rounded tips 403. The clutch body 401 has a limit block 405 at the upper end of the back side, and the upper end surface of the limit block 405 is a cylindrical third separation action surface 406.

[0023] like Figure 7 As shown, the clutch member 4 is arranged in the placement groove 101 and can move radially relative to the output member 1, with a first position where the outer end extends into the first matching groove 201 to make the output member 1 engage with the input wheel 2 and a second position where the output member 1 slides inward to separate from the input wheel 2, and also has a position between the first position and the second position. An elastic acting member 9 is arranged in the placement groove 101, and the elastic acting member 9 exerts a force on the clutch member 4 in the direction from the second position to the first position, so that the clutch member 4 maintains the first position in a normal state, and the first engaging surface 202 is in contact with the first engaging surface 203. The second engagement surface 402 of the clutch 4 at the first position cooperates to form a one-way linkage between the input wheel 2 and the clutch 4, so that the one-way rotation of the input wheel 2 can drive the synchronous rotation of the output member 1. The first separation action surface 203 cooperates with the tip 403 of the clutch 4 at the first position to form a force tending to the second position with the clutch 4 at the first position, so that the one-way rotation of the output member 1 in the opposite direction can drive the clutch 4 to move to the second position, thereby disengaging from the free rotation in the opposite direction of the input wheel 2, and does not drive the input wheel 2, so as to achieve the purpose of clutching. At the same time, the placement groove 101 is a fan-shaped structure, and the clutch 4 can swing at a certain angle relative to the output member 1 in the placement groove 101. When the clutch 4 swings to the two 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, so that the third position of the clutch 4 is as follows Figure 7 As shown, one tip 403 of the clutch member 4 is located in the first matching groove 201 and the other tip 403 is located outside the first matching groove 201 .

[0024] like Figure 6As shown, the in-place action ring 5 is integrally formed on the inner wall of the mechanism box 6, and the inner wall of the in-place action ring 5 is provided with an arc-shaped second matching groove 501, as shown in FIG. Figure 8 As shown, the in-position action ring 5 is sleeved outside the output member 1, the input wheel 2 is adapted to the outer periphery of the in-position action ring 5 and sleeved outside the in-position action ring 5, the matching ring 204 is located outside one axial end of the in-position action ring 5, and the outer end of the clutch member 4 is matched with the inner periphery of the in-position action ring 5 and the inner periphery of the matching ring 204 at the same time. Specifically, the clutch body 401 of the clutch member 4 is located in the matching ring 204, and the limit block 405 of the clutch member 4 is located in the second matching groove 501. The second separation action surface 502 is provided at both ends of the second matching groove 501. The second separation action surface 502 cooperates with the clutch member 4 located in the first position to form a force tending to the second position direction with the clutch member 4 located in the first position; Figure 7 In the structure shown, when the input wheel 2 and the output member 1 further rotate clockwise, the second separation action surface 502 cooperates with the third separation action surface 406 of the clutch member 4 located at the first position, pressing down the clutch member 4 to move it to the third position.

[0025] When the two first engagement surfaces 202 are respectively engaged with the two tips 403, the clutch member 4 is swung left and right in the placement groove 101 to the two ends of the placement groove 101. When the clutch member 4 is swung to one end of the placement groove 101, the distances from the tips 403 at both ends to the center of the output member 1 are different. Figure 7 As shown, when the clutch 4 swings to the left end of the placement groove 101, the distance from the tip 403 of the upper left end of the clutch 4 to the center is smaller than the distance from the tip 403 of the upper right end of the clutch 4 to the center. When the second separation action surface 502 cooperates with the third separation action surface 406 of the clutch 4 located at the first position to press the clutch 4 to the third position, the tip 403 of the upper left end of the clutch 4 enters the placement groove 101 and the tip 403 of the upper right end of the clutch 4 protrudes compared to the placement groove 101. Conversely, when the clutch 4 swings to the right end of the placement groove 101, the distance from the tip 403 of the upper right end of the clutch 4 to the center is smaller than the distance from the tip 403 of the upper left end of the clutch 4 to the center.

[0026] Specifically, the first separation action surface 203 and the second separation action surface 502 are smooth curved surfaces to reduce resistance.

[0027] The action process of the automatic mechanical clutch device of this embodiment is as follows: Figure 9-12 As shown, Fig. 9The figure shows the reverse close to the separation state, the clutch 4 cooperates with the first matching 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 4 abuts against the second separation action surface 502 at the right end of the second matching groove 501 to press the clutch 4 to the third position, at this time, the input wheel 2 rotates clockwise again, and cannot continue to drive the output member 1 to rotate, ensuring that the output member 1 that has rotated to the position cannot be further rotated clockwise under the drive of the input wheel 2; conversely, Fig. 9 When the input wheel 2 in the middle rotates counterclockwise, the upper tip 403 of the right side of the clutch 4 acts on the first separation action surface 203 of the first matching groove 201 at the left end of the input wheel 2, so that the outer end of the clutch 4 can leave the first matching groove 201 at the left end of the input wheel 2 to the second position, until it enters the first matching groove 201 at the right end of the input wheel 2, and rotates to Fig.10 The reverse position shown is ready for engagement. Fig.10 When the input wheel 2 shown in the figure rotates counterclockwise again, the first engaging surface 202 of the first matching groove 201 at the right end of the input wheel 2 cooperates with the right side surface of the clutch member 4, which can drive the clutch member 4 and the output member 1 to rotate counterclockwise to Fig.11 As shown in the positive approaching separation state position, when the input wheel 2 drives the output member 1 to rotate counterclockwise, the third separation action surface 406 of the clutch member 4 abuts against the second separation action surface 502 at the left end of the second matching groove 501 to press the clutch member 4 to the third position. Fig.11 The input wheel 2 in the middle rotates counterclockwise again, and cannot continue to drive the output member 1 to rotate, ensuring that the output member 1 that has been rotated to the right position cannot further rotate counterclockwise under the drive of the input wheel 2; conversely, Fig.11 When the input wheel 2 in the embodiment rotates clockwise, the left upper end tip 403 of the clutch 4 acts on the first separation action surface 203 of the first matching groove 201 at the right end of the input wheel 2, so that the outer end of the clutch 4 can leave the first matching groove 201 at the right end of the input wheel 2 to the second position, until it enters the first matching groove 201 at the left end of the input wheel 2, and rotates to Fig.12 The positive position shown is ready for engagement. Continue to turn clockwise to Fig. 9 The reverse approach position is shown.

[0028] In this embodiment, the positioning action ring 5 is provided to form an automatic positioning mechanical protection for the clutch device, thereby preventing the output member 1 from driving the operating shaft to rotate excessively, thereby causing an electric operation failure.

[0029] like Figure 7 , Figure 8As shown, the elastic acting member 9 is a compression spring, a limiting column 102 cooperating with the elastic acting member 9 is provided at the bottom of the placement groove 101, and a limiting groove 404 cooperating with the elastic acting member 9 is provided at the bottom of the clutch member 4.

[0030] The positioning ring 5 and the mechanism box 6 are integrally formed, 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 positioning ring 5, with a simple and compact structure and convenient assembly.

[0031] In this embodiment, the output shaft of the electric drive element 3 is connected to a worm 7, the outer periphery of the input wheel 2 is a turbine structure, the worm 7 is meshed and driven with the input wheel 2, and both ends of the worm 7 are limited on the mechanism box 6, the structure is simple and compact, and the assembly is convenient. The electric drive element 3 and the input wheel 2 can also be driven by a variable speed gear as needed.

[0032] Fig.13 This is a specific structure in which the electric operating device of this embodiment is applied to a grounding switch. The grounding shaft 8 serves as an operating shaft and extends into the shaft through-hole 103 of the output member 1. It can be electrically operated through a clutch device and can also be manually operated.

[0033] The electric operating device of this embodiment can also be used in conjunction with other switches that require manual or electric operation.

[0034] A person skilled in the art can understand that all or part of the steps in the above-mentioned embodiment method can be completed by instructing related hardware through a program, and the program can be stored in a computer-readable storage medium, such as ROM / RAM, disk, CD-ROM, etc.

[0035] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
