Referring to fig. 1 to 4, the present embodiment provides a clutch mechanism, which includes a rotating shaft 10, a clutch plate 20, a locking plate 30, a first torsion spring 40 and a first elastic member 50 respectively sleeved on the rotating shaft 10, wherein, the clutch plate 20 and the locking plate 30 are fixedly connected with the rotating shaft 10, the first torsion spring 40 is positioned between the clutch plate 20 and the locking plate 30, one end of the first torsion spring 40 is used for being connected with the energy storage plate 60 of the remote power-off device, the other end is used for being connected with the bracket 210 of the remote power-off device, one side of the clutch plate 20 far away from the locking plate 30 is provided with a first sliding part 21, the first sliding part 21 is used for being in sliding connection with a second sliding part 61 on the energy storage plate 60, so as to drive the energy storage disc 60 to rotate, the first elastic element 50 is used for driving the first sliding part 21 to slide in the second sliding part 61, so that the first sliding part 21 is reset, the locking plate 30 rotates to drive the limit locking device 220 of the remote power-off device to lock or disengage the energy storage plate 60.

Wherein, one end of the first torsion spring 40 is used for being connected with the energy storage plate 60 of the remote power-off device, and the other end is used for being connected with the bracket 210 of the remote power-off device. Thus, when the energy storage plate 60 rotates in a first direction relative to the bracket 210, the first torsion spring 40 stores energy; when the energy storage plate 60 rotates relative to the bracket 210 in the second direction (the second direction is opposite to the first direction), the first torsion spring 40 releases the stored energy.

The first elastic member 50 is provided to provide a restoring force to the locking plate 30 and the clutch plate 20 after the stored energy of the first torsion spring 40 is released, so that the locking plate 30 and the clutch plate 20 can restore to the original positions.

For example, in the present embodiment, the first elastic member 50 may be a second torsion spring, one end of which is used for being fixedly connected with the bracket 210, and the other end of which is used for being slidably connected with the bracket 210 through the locking plate 30. Thus, when the locking plate 30 rotates in the first direction relative to the bracket 210, the second torsion spring also stores energy; when the locking plate 30 rotates in the second direction relative to the bracket 210, the second torsion spring also releases the stored energy.

In other embodiments, one end of the first elastic member 50 may be connected to the first sliding portion 21, and the other end may be connected to one end of the first torsion spring 40 connected to the energy storage plate 60. Specifically, the first elastic member 50 may be disposed at a position and in a manner that a person skilled in the art can set itself, as long as it can provide a restoring force for the locking plate 30 and the clutch plate 20 after the stored energy of the first torsion spring 40 is released, so that the locking plate 30 and the clutch plate 20 can restore to the initial positions.

The working principle of the clutch mechanism provided by the embodiment is as follows:

in the initial state: the limiting lock catch 220 is abutted against the lock catch disc 30 of the remote power-off device, and the limiting lock catch 220 locks the energy storage disc 60;

in the energy storage state: when the rotating shaft 10 is rotated, the latch plate 30 is separated from the limit latch 220 of the remote power-off device, so that the limit latch 220 loses the limit on the energy storage plate 60; when the first sliding portion 21 of the clutch plate 20 slides from one end of the second sliding portion 61 of the energy storage plate 60 to the other end, the clutch plate 20 drives the energy storage plate 60 to rotate synchronously with the rotating shaft 10, so that the first torsion spring 40 stores energy.

In the energy storage release state: the energy storage plate 60 rotates to the initial position under the action of the first torsion spring 40, and the clutch plate 20 and the locking plate 30 also rotate to the initial position under the action of the first elastic member 50, so as to lock the energy storage plate 60.

In conclusion, the clutch mechanism provided by the embodiment can ensure that the energy storage disc 60 is smoothly separated from the locked state to perform energy storage operation, so that the normal work blockage caused by the blockage of the energy storage disc 60 of the remote power-off device is prevented.

The rotating shaft 10 may be used to drive the clutch plate 20 and the locking plate 30 to rotate. In order to facilitate the rotation of the rotating shaft 10, in this embodiment, the clutch mechanism further includes a handle 11 sleeved and fixedly connected to one end of the rotating shaft 10. Therefore, the rotating shaft 10 can be driven to rotate only by operating the handle 11, the operation is convenient, and the practicability is stronger.

When the first elastic element 50 is a second torsion spring, further, please refer to fig. 8 in combination, the clutch mechanism provided in this embodiment further includes a sleeve 70, the sleeve 70 is sleeved on the rotating shaft 10 and located between the clutch disc 20 and the locking disc 30, the sleeve 70 includes a cylinder 71 and a stopping portion 72 disposed on an outer peripheral wall of the cylinder 71, the stopping portion 72 is used for dividing the cylinder 71 into a first sub-cylinder 73 and a second sub-cylinder 74 which are connected to each other, the first torsion spring 40 is sleeved on the outer peripheral wall of the first sub-cylinder 73, and the second torsion spring is sleeved on the outer peripheral wall of the second sub-cylinder 74. Thus, the first torsion spring 40 and the second torsion spring can be respectively sleeved on the first sub-cylinder 73 and the second sub-cylinder 74, so as to prevent the first torsion spring 40 and the second torsion spring from influencing each other.

Specifically, in the present embodiment, the stopper 72 is an annular partition plate that is provided around the outer circumferential wall of the cylinder 71. Of course, in another embodiment, the stopping portions 72 may be two partition plates oppositely disposed on the outer circumferential wall of the cylinder 71.

In the embodiment, referring to fig. 6, the latch plate 30 includes a first body 31 sleeved on the rotating shaft 10, a first push rod 32 and a second push rod 33 extending from the first body 31 in a direction away from the rotating shaft 10, the first push rod 32 is used for pushing the limiting latch 220, and the second push rod 33 is used for driving the energy storage latch 230 of the remote power-off device, so that the energy storage latch 230 limits the energy storage plate 60.

Specifically, in the initial state, the limit latch 220 of the remote power-off device abuts against the first push rod 32, so that the limit latch 220 locks the energy storage disk 60; when the rotating shaft 10 rotates in the first direction, the first push rod 32 disengages from the limiting lock catch 220, and the energy storage disc 60 loses the limitation of the limiting lock catch 220; the rotating shaft 10 continues to rotate along the first direction, the energy storage disc 60 rotates along with the clutch disc 20, the energy storage disc 60 rotates to the right position, and the second push rod 33 can be used for driving the energy storage latch 230 of the remote power-off device, so that the energy storage latch 230 is driven to limit the energy storage disc 60.

The application also provides a remote power-off device, which comprises the clutch mechanism, a linkage rod 260, a support 210, an energy storage disc 60, a limiting lock catch 220, an energy storage lock catch 230 and a guide mechanism 240, wherein a first sliding part 21 of the clutch mechanism is in sliding connection with a second sliding part 61 of the energy storage disc 60, the support 210 is arranged on the rotating shaft 10 in a penetrating manner and is positioned on one surface of the lock catch disc 30, which is far away from the energy storage disc 60, the limiting lock catch 220 and the energy storage lock catch 230 are respectively hinged on two opposite sides of the support 210, the limiting lock catch 220 abuts against the lock catch disc 30, so that one end, which is far away from the lock catch disc 30, of the limiting lock catch 220 locks the energy storage disc 60, and the guide mechanism 240 is not in contact with the energy; the energy storage disc 60 is connected with one end of the linkage 260, and the other end of the linkage 260 is used for connecting the clutch switch.

When the rotating shaft 10 is rotated in the forward direction, the locking disc 30 can be separated from the limiting lock catch 220, the clutch disc 20 drives the energy storage disc 60 to rotate, the locking disc 30 pushes one end of the guide mechanism 240, and the energy storage lock catch 230 abuts against the guide mechanism 240, so that one end of the energy storage lock catch 230, which is far away from the bracket 210, limits the energy storage disc 60; when the rotating shaft 10 is rotated reversely, the energy storage latch 230 locks the energy storage disc 60, and the latch disc 30 pushes one end of the guide mechanism 240 to disengage from the guide mechanism 240.

It should be noted that, first, the structure of the clutch mechanism and the beneficial effects thereof have been described and illustrated in detail in the foregoing, and therefore, are not described herein again.

Second, the limit latch 220 and the energy storage latch 230 are hinged to two opposite sides of the bracket 210 by pins, respectively.

Thus, when in the initial state: referring to fig. 1 again, the limiting latch 220 abuts against the latch plate 30, and one end of the limiting latch 220 away from the bracket 210 limits and locks the energy storage plate 60, at this time, the energy storage plate 60 cannot rotate, and the clutch switch cannot be pulled.

In the energy storage state: referring to fig. 2 again, when the rotating shaft 10 rotates in the forward direction (i.e., clockwise), the locking plate 30 and the clutch plate 20 rotate along with the rotating shaft 10, the locking plate 30 is disengaged from the limiting lock 220, and the limiting lock 220 rotates on one side of the bracket 210, so that the energy storage plate 60 is unlocked; when the rotating shaft 10 continues to rotate along the first direction, the clutch disc 20 drives the energy storage disc 60 to rotate, and the first torsion spring 40 stores energy; when the locking disc 30 rotates a certain angle, the locking disc 30 pushes the guiding mechanism 240 at this time, so that the guiding mechanism 240 moves to a position, and the energy storage locking 230 contacts with the guiding mechanism 240 and abuts against the surface of the guiding mechanism 240; when the rotating shaft 10 stops rotating, the stored energy of the first torsion spring 40 is released, and the rotating shaft 10 rotates in the reverse direction (i.e. counterclockwise), but due to the existence of the energy storage latch 230, the energy storage disc 60 is locked by the energy storage latch 230, and due to the sliding relationship between the energy storage disc 60 and the clutch mechanism, the clutch disc 20 and the latch disc 30 rotate by themselves by a certain angle to enable one end of the latch disc 30, which is previously abutted against the pushing guide mechanism 240, to be disengaged from the guide mechanism 240.

Upon receiving a power down signal: the guide mechanism 240 is separated from the energy storage lock catch 230 in a butting manner, the energy storage lock catch 230 is rotated and reset on one side of the support 210, then the energy storage disc 60 loses the limitation of the energy storage lock catch 230, the energy storage disc 60 is unlocked, the energy storage of the first torsion spring 40 is released, the energy storage disc 60 rotates under the action of the first torsion spring 40, the linkage rod 260 is pulled, and the isolating switch is pulled by the linkage rod 260 to switch off the circuit; after the energy storage disc 60 rotates to the position, the locking disc 30 pushes the limiting locking buckle 220 to rotate to enter a limiting locking state, the energy storage disc 60 is locked by one end, far away from the support 210, of the limiting locking buckle 220, and at the moment, the linkage rod 260 cannot pull the energy storage disc 60 to rotate.

Further, referring to fig. 11, the guiding mechanism 240 includes a second body 241 disposed on a surface of the bracket 210 away from the locking plate 30, an accommodating cavity 2411 disposed on the second body 241, and a guiding flange 242 connected to the second body 241, wherein one end of the energy storage locking device 230 close to the bracket 210 can pass through the bracket 210 and extend into the accommodating cavity 2411 of the second body 241, and the guiding flange 242 is slidably connected to the first sliding groove 211 of the bracket 210 and extends out of the first sliding groove 211; when the rotating shaft 10 is rotated in the forward direction, the locking disc 30 pushes the guiding flange 242 to move the guiding mechanism 240, so that the energy storage locking device 230 is separated from the accommodating cavity 2411, the energy storage locking device 230 abuts against the surface of the second body 241, and the energy storage locking device 230 is away from the end-limiting energy storage disc 60 of the bracket 210.

In addition, the embodiment further includes a driving mechanism 250, and when the power-off signal is received, the driving mechanism 250 is configured to drive the second body 241, so as to move the second body 241, so that the energy storage latch 230 enters the accommodating cavity 2411 of the second body 241, and then the energy storage latch 230 loses the limitation of the second body 241, and is reset to the initial position, and the energy storage disk 60 is unlocked.

It should be noted that, referring to fig. 7, the energy storage disk 60 in this embodiment should have two outer protrusions (i.e., a first outer protrusion and a second outer protrusion). The first outer convex part is used for limiting and abutting against the limiting lock catch 220, and the second outer convex part is used for limiting and abutting against the energy storage lock catch 230. When the energy storage disc 60 is in the initial position, the first outer convex part is abutted to the limiting lock catch 220 to lock the energy storage disc 60; when the rotating shaft 10 is rotated in the forward direction, the lock catch disc 30 and the limiting lock catch 220 are separated from abutting, and the first outer convex part and the limiting lock catch 220 are unlocked; when the rotating shaft 10 is rotated continuously, the clutch disc 20 drives the energy storage disc 60 to rotate, the second outer convex part of the energy storage disc 60 rotates to one side close to the energy storage latch 230, at this time, the latch disc 30 pushes the guide mechanism 240, the energy storage latch 230 abuts against the guide mechanism 240, the energy storage latch 230 limits the second outer convex part of the energy storage disc 60, and when the rotating shaft 10 is rotated reversely, the energy storage latch 230 abuts against the second outer convex part, so that the energy storage disc 60 is locked.

Further, referring to fig. 9, the limit latch 220 includes a third body 221 and a first baffle 222 connected to each other, an end of the third body 221 away from the first baffle 222 is provided with an arc notch 223, a first inclined surface 224 and a first locking surface 225, the first inclined surface 224 is connected between the arc notch 223 and the first locking surface 225, the first baffle 222 is used for limiting the locking of the energy storage disk 60, and the first locking surface 225 can abut against the lock disk 30.

Thus, the first inclined surface 224 can play a transition role, when the lock catch disc 30 needs to be separated from the limit lock catch 220, the rotating shaft 10 is rotated in the forward direction, the lock catch disc 30 firstly rotates to the first inclined surface 224 and then rotates to the arc-shaped notch 223, so as to be far away from the limit lock catch 220, and then the limit lock catch 220 is rotated and reset; when the locking plate 30 reversely rotates under the action of the first elastic element 50, the locking plate 30 first rotates to the arc-shaped notch 223, and then one side of the locking plate abuts against the first inclined surface 224, so as to push the first inclined surface 224 to rotate the limiting lock 220, and thus the limiting lock 220 abuts against the locking plate 30.

Further, referring to fig. 10, the energy storage latch 230 includes a fourth body 231 and a second baffle 232, the second baffle 232 is used for limiting the energy storage disk 60, a second inclined surface 233 and a second locking surface 234 are disposed at an end of the fourth body 231 away from the second baffle 232, and the second locking surface 234 can abut against the guide mechanism 240.

In the initial state, the end of the fourth body 231 having the second inclined surface 233 is not in contact with the guide mechanism 240; when the energy storage latch 230 needs to limit the rotation of the energy storage disk 60, and the rotating shaft 10 is rotated in the forward direction, the latch disk 30 drives the guide mechanism 240 to move, so that the guide mechanism 240 first pushes the second inclined surface 233 of the energy storage latch 230, and then the energy storage latch 230 rotates, so that the second locking surface 234 of the energy storage latch 230 abuts against the guide mechanism 240; when the energy storage latch 230 needs to unlock the energy storage disk 60, the guide mechanism 240 is driven, so that one end of the guide mechanism 240, which is abutted to the energy storage latch 230, is separated from the guide mechanism 240, at this time, the energy storage latch 230 is reset, and the energy storage disk 60 is unlocked.
