The detection assembly 1 can be an infrared detection assembly, an ultrasonic detection assembly, a laser detection assembly, a visual detection assembly and the like.

The detection assembly 1 is arranged on the movable mechanism 22, and the driving mechanism 21 drives the movable mechanism 22 to stretch and retract so as to drive the detection assembly 1 to stretch and retract. Wherein, as shown in fig. 1, through will actuating mechanism 21 sets up the side of moving mechanism 22, will actuating mechanism 21 sets up moving mechanism 22's side, actuating mechanism 21 drives from the side moving mechanism 22 is flexible, makes actuating mechanism 21 with moving mechanism 22's partial structure coincides in the direction of height, thereby reduces telescopic component 2's height is convenient for thin the overall structure of machine of sweeping the floor makes the machine of sweeping the floor conveniently get into low space and cleans.

Specifically, as shown in fig. 2, a support rod 3 is provided between the drive mechanism 21 and the movable mechanism 22, and the support rod 3 is horizontally provided between the drive mechanism 21 and the movable mechanism 22. The driving mechanism 21 comprises an electric driver 4 and a lifting cylinder 23, the top of the lifting cylinder 23 is provided with an oblique section end surface 24, and the bottom of the lifting cylinder 23 is connected with a driving shaft of the electric driver 4; the movable mechanism 22 comprises a telescopic column 25, and the detection assembly 1 is arranged on the telescopic end face of the telescopic column 25. One end of the support rod 3 is fixedly arranged on the telescopic column 25, and the other end of the support rod 3 is a free end which is movably arranged on the inclined section end surface 24. The electric drive 4 may be a motor such as a dc motor, an ac motor, or a servo motor.

In this embodiment, the truncated end surface 24 supports the telescopic column 25 through the support rod 3, the electric actuator 4 drives the lifting cylinder 23 to rotate, so that the lifting cylinder 23 rotates around the longitudinal central axis thereof, and the free end of the support rod 3 is movably arranged on the truncated end surface 24 of the lifting cylinder 23, so that the support rod 3 can lift the movable mechanism 22 due to the change of the longitudinal height of the truncated end surface 24, thereby realizing the telescopic motion of the detection assembly 1.

Through inciting somebody to action actuating mechanism 21 sets up the side of movable mechanism 22 to the supporting rod 3 that adopts the level to set up realizes the transmission, reduces actuating mechanism 21 with longitudinal interval between the movable mechanism 22, thereby reduces the longitudinal length of flexible subassembly 2, the overall structure of thinization machine of sweeping the floor of being convenient for, just choose for use electric drive 4 is as the power supply, and occupation space is little, conveniently sweeps the distribution inner space of machine.

Further, the moving mechanism 22 further comprises a guide pillar 26, the guide pillar 26 is provided with a guide groove 27, the side wall of the telescopic column 25 is provided with a convex edge 28, and the convex edge 28 is connected with the guide groove 27. Specifically, as shown in fig. 3 and 4, the guide post 26 is provided with the guide groove 27, the side wall of the telescopic post 25 is provided with the convex edge 28 for connecting with the guide groove 27, and the telescopic post 25 can keep linear motion by matching the convex edge 28 with the guide groove 27, and simultaneously, the telescopic post 25 is prevented from rotating. Further, the number of the guide support columns 26 is at least two, the two guide support columns 26 are vertically arranged on two sides of the telescopic column 25 in a pairwise symmetrical mode, the number of the convex edges 28 is the same as that of the guide support columns 26, and by arranging the two or more guide support columns 26, the structure is reasonable, and the guide capacity of the guide support columns to the telescopic column 25 is enhanced.

Further, rolling bodies are provided between the guide groove 27 and the raised edge 28. Since the support rod 3 is horizontally disposed between the driving mechanism 21 and the movable mechanism 22, when the support rod 3 moves up and down the telescopic column 25 due to the change in the longitudinal height of the truncated end surface 24, the support rod 3 applies a tangential component force and a vertical support force to the telescopic column 25, and the tangential component force increases the friction between the flange 28 and the guide groove 27, which results in the unsmooth extension and retraction of the detecting unit 1. Therefore, rolling elements such as pulleys and balls are arranged between the guide groove 27 and the convex edge 28, rolling friction is adopted to replace sliding friction, and the detection assembly 1 can stretch smoothly on the premise of reducing the longitudinal length of the telescopic assembly 2.

Preferably, as shown in fig. 4, a sliding base 29 is disposed in the guide groove 27, the sliding base 29 slides along the length direction of the guide groove 27, the sliding base 29 is provided with a plurality of pulleys 30 contacting with the guide groove 27 on the outer wall thereof, the sliding base 29 is further provided with a connecting groove 31, and the convex edge 28 is connected with the connecting groove 31 in a matching manner.

Further, the lifting cylinder 23 is a hollow structure, the lifting cylinder 23 includes a bottom end surface to which the electric driver 4 is connected, and a side wall for supporting the support rod 3. Adopt hollow cylinder as lift cylinder 23, through the lateral wall supporting bearing pole 3 reduces the weight of lift cylinder 23 adopts low-power electric drive 4 can satisfy the drive demand, consequently electric drive 4 can be miniaturized, further reduces telescopic machanism 3's vertical thickness does benefit to the structure thinization of machine of sweeping the floor, and reduces occupation space, is convenient for other subassemblies to distribute the residual space.

Further, the free end of the support rod 3 is provided with a roller 32. Since the support rod 3 is horizontally disposed between the drive mechanism 21 and the movable mechanism 22, and the support rod 3 is easily bent and deformed by a frictional force in a tangential direction when the support rod 3 is moved up and down the telescopic column 25 due to a change in the longitudinal height of the truncated end surface 24, the truncated end surface 24 is movably disposed at a free end of the support rod 3 in a rolling manner by providing the roller 32 at the free end of the support rod 3, so that friction between the support rod 3 and the truncated end surface 24 is reduced, and the force applied to the support rod 3 is reduced.

Preferably, when the support rod 3 is located at the lowest end of the truncated end surface 24, the outer end surface of the detection assembly 1 is flush with the outer end surface of the sweeper. When the supporting rod 3 is located at the lowest end of the truncated end face 24, the detection assembly 1 is just completely retracted into the sweeper, so that a vacant longitudinal space is avoided, and the longitudinal length of the telescopic assembly 2 is reasonably reduced.

Preferably, the stroke of the detection assembly 1 in the vertical direction relative to the sweeper is H, wherein H is more than or equal to 0mm and less than or equal to 70 mm.
