The working principle of the brake clutch device during power-off braking is as follows: wherein, when the adjusting disc 31 is in an active state, that is, there is no engagement between the buckle portion 35 and the groove portion 36 . Here's how it works:

Among them, in order to facilitate the description of the working principle of the brake clutch device, the present invention has additional working principle diagrams, namely Fig. 4 and Fig. 5; in addition, the two connecting parts 17 are subdivided into the first connecting part 24 and the second connecting part 24 for the convenience of distinction. Two connecting parts 25 .

When the external motor drives the first rotating disk 11 to rotate in the forward direction, the first fixed column 18 follows and rotates and squeezes the second connecting part 25, thereby driving the second rotating disk 13 to rotate. At this time, as shown in FIG. 7, the first The two engaging parts 25 are in an active state; at the same time, the spring pushes the first engaging part 24 to move towards the first fixed column 18, so that the first engaging part 24 locks the second rotating disk 13 and the third rotating disk 16, thus When the third rotating disc 16 rotates synchronously.

When the external motor suddenly loses power and stops rotating, the first rotating disk 11 and the first fixed column 18 stop moving, and the second rotating disk 13 continues to rotate in the forward direction under the action of inertia. The column has a counterclockwise relative movement with respect to the second rotating disk 13, at this time the first fixed column 18 pushes the first joint part 24, and makes the first joint part 24 in an active state, as shown in Figure 8, while the spring pushes The second engaging portion 25 moves toward the first fixing column 18 , so that the first engaging portion 24 locks the second rotating disk 13 and the third rotating disk 16 . Realized the function of power failure self-locking.

In addition, the present invention can also be provided with a reset drive mechanism on the first fixed column 18. The reset drive mechanism has two output ends that push the first engagement portion 24 and the second engagement portion 25 respectively. By controlling the reset drive mechanism, the first Both the first connecting part 24 and the second connecting part 25 are in an active state, thereby realizing the clutch of the device.

When the external motor drives the first rotating disk 11 to rotate in the reverse direction, the working principle is similar to that of the first rotating disk 11 rotating in the reverse direction. Those skilled in the art should understand that, and will not go into details here.

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

When realizing the clutch function, turn the adjustment dial 31 to a certain angle, and make the adjustment dial 31 in the locked state, that is, the engagement between the buckle part 35 and the groove part 36, at this time the adjustment dial 31 drives the rotating part 27 to rotate synchronously At a certain angle, the cam portion 26 drives the first engaging portion 24 and the second driving portion 25 away from the first fixing column 18 respectively, and the clutch function is realized at this time.

For those skilled in the art, without departing from the inventive concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention.
