The working principle of the brake clutch device during power-off braking is as follows: when the adjustment disc 31 is in the active state, the locking portion 35 and the locking portion 36 are not locked with each other. The working principle at this time is as follows:

in order to facilitate the description of the working principle of the brake clutch device, the invention is added with working principle diagrams, namely, figures 4 and 5; in addition, the two engagement portions 17 are subdivided into a first engagement portion 24 and a second engagement portion 25 for the sake of easy distinction.

When the external motor drives the first rotating disk 11 to rotate forward, the first fixing column 18 rotates along with the first rotating disk and presses the second connecting part 25, so that the second rotating disk 13 is driven to rotate, and at the moment, as shown in fig. 7, the second connecting part 25 is in a movable state; at the same time, the spring pushes the first engagement portion 24 toward the first fixed post 18, so that the first engagement portion 24 locks the second rotary disk 13 and the third rotary disk 16, and the third rotary disk 16 is rotated simultaneously.

When the external motor is suddenly powered off and stops rotating, the first rotating disk 11 and the first fixed column 18 stop moving, the second rotating disk 13 continues to rotate in the forward direction under the action of inertia, namely, the second rotating disk rotates clockwise, but the first fixed column has anticlockwise relative motion relative to the second rotating disk 13, at this time, the first fixed column 18 pushes the first connecting part 24, the first connecting part 24 is enabled to be in an active state, as shown in fig. 8, and meanwhile, the spring pushes the second connecting part 25 to move towards the first fixed column 18, so that the first connecting part 24 locks the second rotating disk 13 and the third rotating disk 16. The power-off self-locking function is realized.

In addition, the invention can also arrange a reset driving mechanism on the first fixing column 18, the reset driving mechanism is provided with two output ends which respectively push the first connecting part 24 and the second connecting part 25, and the first connecting part 24 and the second connecting part 25 can be in a movable state by controlling the reset driving mechanism, thereby realizing the clutch of the device.

When the external motor drives the first rotary disk 11 to rotate reversely, the working principle is similar to that when the first rotary disk 11 rotates reversely, and it should be understood by those skilled in the art that detailed description is omitted here.

In the present invention, in the initial state, the first engaging portion 24 and the second engaging portion 25 are under the action of the first fixing post 18, and the first engaging portion 24 and the second engaging portion 25 are not in pressure contact with the third rotating disc 16, so that the third rotating disc 16 can drive the rotating shaft 22 to move freely. Once the external drive rotates the first rotary disk 11, the rotary shaft 22 can only follow the corresponding movement of the external drive according to the above working principle.

When the clutch function is realized, the adjusting disc 31 is rotated by a certain angle, and when the adjusting disc 31 is in a locked state, i.e. the fastening portion 35 is fastened with the fastening portion 36, the adjusting disc 31 drives the rotating portion 27 to synchronously rotate by a certain angle, so that the cam portion 26 drives the first fastening portion 24 and the second fastening portion 25 to be away from the first fastening post 18, respectively, and the clutch function is realized at this time.

It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the inventive concept thereof, and these changes and modifications can be made without departing from the spirit and scope of the invention.
