Under normal conditions, the driving wheel structure 200 can drive the whole driving wheel mechanism 30 to move, and the auxiliary wheel structure 300 can play a role of auxiliary movement. The wheel slip detection structure 400 can detect whether the driving wheel structure 200 slips, and when the driving wheel structure 200 slips, the auxiliary wheel structure 300 can also actively drive the driving wheel mechanism 30, so as to help the driving wheel structure 200 to break away from the slipping situation.

Specifically, as shown in fig. 2, the driving wheel structure 200 may include a main shaft 210 disposed on the frame 100, a main driving roller 220 disposed on the main shaft 210, and a main driving member 230 connected to the main shaft 210. The driving wheel structure 200 can drive the main shaft 210 to rotate under the driving action of the main driving member 230, and can drive the main driving roller 220 to rotate, so as to drive the frame 100 and the whole driving wheel mechanism 30 to move.

That is, one rotation speed sensor may be provided to monitor one main driving roller 220, or a plurality of rotation speed sensors may be provided to monitor a plurality of main driving rollers 220 one-to-one.

In the present embodiment, as shown in fig. 4 to fig. 6, the driving wheel structure 200 may include a main rotating shaft 210 and a main driving roller 220 respectively disposed at two ends of the main rotating shaft 210, and a main driving member 230 is connected to the main rotating shaft 210, and two main driving rollers 220 may be simultaneously driven to rotate by the main driving member 230. Also, the wheel slip detecting structure 400 may include two rotation speed sensors in one-to-one correspondence with the two main drive wheels 220. The two rotation speed sensors can respectively detect whether the two main driving rollers 220 slip or not, and are connected with the switch controller.

In addition, the driving wheel structure 200 may also include a plurality of main shafts 210 and a plurality of main driving rollers 220 connected to the plurality of main shafts 210 (which may be connected in a one-to-one correspondence, or one main shaft 210 may be connected to a plurality of main driving rollers 220 in a corresponding manner). Moreover, one main driving member 230 may be provided, that is, a plurality of main driving rollers 220 may be simultaneously driven by one main driving member 230; in addition, a plurality of main driving members 230 may be provided, i.e., a plurality of main driving rollers 220 may be driven by a plurality of main driving members 230 at the same time. In addition, the driving wheel structure 200 may also include a main shaft 210 and a main driving roller 220 connected to the main shaft 210.

In this embodiment, as shown in fig. 4 to 6, the auxiliary wheel structure 300 may include an auxiliary rotating shaft 310, an auxiliary roller 320 disposed on the auxiliary rotating shaft 310, and an auxiliary driving member 330 connected to the auxiliary rotating shaft 310.

Further, as shown in fig. 4, each of the primary driving member 230 and the secondary driving member 330 may include a driving motor disposed on the rack 100, and a driving transmission structure connected to an output shaft of the driving motor, the driving transmission structure being connected to the primary rotating shaft 210 or the secondary rotating shaft 310, and the driving motor 332 of the secondary driving member 330 being connected to the switch controller. That is, the driving wheel structure 200 and the auxiliary wheel structure 300 have their corresponding driving motors and driving transmission structures, respectively, and independent driving can be realized.

That is, the main driving member 230 may include a first driving motor 232 disposed on the rack 100, and a first driving transmission structure 234 connected to an output shaft of the first driving motor 232, wherein the first driving transmission structure 234 is connected to the main rotating shaft 210. The first driving transmission structure 234 can be driven by the first driving motor 232 to operate, so that the first driving transmission structure 234 drives the main shaft 210 to rotate, thereby driving the main driving roller 220 to rotate.

Similarly, the auxiliary driving member 330 may include a second driving motor 332 disposed on the rack 100, and a second driving transmission structure 334 connected to an output shaft of the second driving motor 332, wherein the second driving transmission structure 334 is connected to the auxiliary rotating shaft 310. The second driving transmission structure 334 is driven by the second driving motor 332 to operate, so that the second driving transmission structure 334 drives the auxiliary rotating shaft 310 to rotate, thereby driving the auxiliary driving roller 320 to rotate.

Further, as shown in fig. 5 to 6, the primary and secondary driving members 230 and 330 may include a common driving motor provided on the rack 100, a first driving transmission structure 234 connecting an output shaft of the driving motor and the primary rotation shaft 210, a clutch mechanism (not shown) connecting the output shaft of the driving motor, and a second driving transmission structure 334 connecting the clutch mechanism and the secondary rotation shaft 310, the clutch mechanism being connected to the switching controller. The driving wheel structure 200 and the auxiliary wheel structure 300 can share the driving motor, and the cost is saved. The first driving transmission structure 234 can be directly driven to work by the driving motor, so that the first driving transmission structure 234 drives the main shaft 210 to rotate, thereby driving the main driving roller 220 to rotate. The switch controller can control the operation of the clutch mechanism to connect or disconnect the output shaft of the driving motor and the second driving transmission structure 334, so that the second driving transmission structure 334 drives the auxiliary rotating shaft 310 to rotate or does not drive the auxiliary rotating shaft 310 to rotate, thereby driving or not driving the auxiliary roller 320 to rotate.

Furthermore, the clutch mechanism may include a clutch actuator disposed on the frame 100, and a clutch actuator connected to the clutch actuator and disposed between the auxiliary rotating shaft 310 and the second driving transmission structure 334. The clutch driver is connected with the switch controller, and when the rotation speed sensor detects that the main driving roller 220 slips, the switch controller can control the clutch driver to work, so that the clutch driver drives the clutch actuator to communicate the auxiliary rotating shaft 310 and the second driving transmission structure 334; when the rotation speed sensor does not detect the slipping of the main driving roller 220, the switch controller does not control the operation of the clutch driver, so that the clutch driver does not drive the clutch actuator to communicate the auxiliary rotating shaft 310 with the second driving transmission structure 334, and thus the auxiliary rotating shaft 310 is disconnected from the second driving transmission structure 334 and does not actively drive the auxiliary roller 32 to rotate. In addition, it should be noted that the clutch actuator and clutch actuator are similar to the clutch in the conventional automobile or other existing equipment, and belong to the prior art, and are not described herein again.

The first drive transmission structure 234 may be one of a gear transmission structure, a sprocket transmission structure, and a pulley transmission structure, and the second drive transmission structure 334 may be one of a gear transmission structure, a sprocket transmission structure, and a pulley transmission structure. In the present embodiment, the first drive transmission structure 234 and the second drive transmission structure 334 can both be provided as gear transmission structures.

In addition, the driving wheel mechanism 30 may include at least one driving wheel structure 200 and at least one auxiliary wheel structure 300 provided on the frame 100. That is, the driving wheel mechanism 30 may include one or more driving wheel structures 200 provided on the frame 100, and may also include one or more auxiliary wheel structures 300 provided on the frame 100.

In this embodiment, as shown in fig. 4 to 6, the driving wheel mechanism 30 may include a driving wheel structure 200 and an auxiliary wheel structure 300 provided on the frame 100. Moreover, the driving wheel structure 200 may include a main shaft 210 rotatably disposed on the frame 100, and two main driving rollers 220 disposed on the main shaft 210; the auxiliary wheel structure 300 may include an auxiliary shaft 310 rotatably disposed on the frame 100, and an auxiliary wheel 320 disposed on the auxiliary shaft 310.

Furthermore, the auxiliary wheel structure 300 may be a universal wheel structure, which can not only rotate but also change the direction of the vehicle, and can change the moving direction of the driving wheel mechanism 30. Specifically, a shaft mounting bracket 340 may be rotatably provided on the frame 100, and the auxiliary rotating shaft 310 may be rotatably installed at the shaft mounting bracket 340, and the auxiliary roller 320 may be installed at the auxiliary rotating shaft 310, so that the auxiliary wheel structure 300 has a universal rotation function.

Example 2

As shown in fig. 7 to 8, the present embodiment provides a cleaning apparatus 10 including an apparatus body 20, and a driving wheel mechanism 30 provided at the bottom of the apparatus body 20. The chassis 100 of the drive wheel mechanism 30 may be attached to the bottom of the apparatus body 20, or may be integrated with the bottom of the apparatus body 20. The surface to be cleaned can be cleaned through the device body 20, dirt such as dust, sundries, stains and the like on the surface to be cleaned can be removed, and the surface to be cleaned can be kept clean. The drive wheel mechanism 30 can drive the apparatus body 20 so that the cleaning apparatus 10 moves on the surface to be cleaned.

When the cleaning device moves on a surface to be cleaned during cleaning, the main driving roller 220 of the driving wheel mechanism 30 may slip when encountering a step or a slippery floor, so that the cleaning device cannot move normally. At this time, when the wheel slip detection structure 400 disposed on the driving wheel mechanism 30 detects that the main driving wheel 220 slips and cannot move normally, the auxiliary driving member 330 of the auxiliary wheel structure 300 can be started, so that the auxiliary driving member 330 actively drives the auxiliary wheel 320 to rotate, and thus the auxiliary driving wheel structure 200 of the auxiliary wheel structure 300 drives and moves the whole driving wheel mechanism 30 together, so as to overcome the problem that the main driving wheel 220 slips and cannot move normally. Therefore, the cleaning device 10 can be ensured to normally move when slipping occurs, the cleaning surface can be normally cleaned, and the cleaning efficiency and the cleaning effect are ensured.

The cleaning device may be a floor sweeping robot, a floor washer, an unmanned floor washer, a vacuum cleaner, or the like.

It is obvious that the above described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the embodiments in the present invention, a person skilled in the art can make changes or changes in other different forms without creative work, and all should belong to the protection scope of the present invention.
