[0143] Compared with the top brush anti-falling structure in the first embodiment, the top blowing anti-falling structure in the second embodiment can bear a larger load.

[0144] From the above description, it can be seen that the above-mentioned embodiments of the present application achieve the following technical effects:

[0145] In the anti-falling mechanism suitable for the preset mechanism 60 provided by the present application, the preset mechanism 60 is used to be connected with the second end of the transmission piece 90, so that the transmission piece 90 drives the preset mechanism 60 to move along the vertical direction; wherein the transmission piece 90 has oppositely arranged first and second ends, and the first end of the transmission piece 90 is used to be connected with the driving assembly 80, so that the driving assembly 80 drives the preset mechanism 60 to move along the vertical direction through the transmission piece 90.

[0146] The anti-falling mechanism comprises a fixed frame 10 and a locking piece 20, and the fixed frame 10 is provided with a plurality of locking matching portions 11 distributed along the vertical direction.

[0147] The locking member 20, the preset mechanism 60 and the second end of the transmission member 90 are connected with each other; the locking member 20 has a normal state and a locking state.

[0148] When the first end and the second end of the transmission member 90 are not broken, the locking member 20 is in the normal state, and the locking member 20 is not locked with each locking matching part 11, so that the locking member 20 moves along with the transmission member 90 in the vertical direction.

[0149] When the first end and the second end of the transmission member 90 are broken, the locking member 20 and the preset mechanism 60 fall down together, and at this time, the locking member 20 changes from the normal state to the locking state, so that the locking member 20 is locked with one of the locking matching parts 11, thereby preventing the preset mechanism 60 from continuing to fall down through the locking of the locking member 20 and the one of the locking matching parts 11.

[0150] The anti-falling mechanism of the present application is a pure mechanical structure, which can prevent the top brushing mechanism and the top blowing mechanism from falling down accidentally, thereby avoiding damage to the vehicle caused by the accidental falling of the top brushing mechanism or the top blowing mechanism. In addition, the mechanical anti-falling structure can eliminate the hidden danger of electrical faults.
