Detailed Description

The specific structure of the present utility model will be described in detail with reference to fig. 1 to 5. The floor cleaning machine comprises a cleaning machine main body 1, wherein an electric cabinet 5 is arranged on the upper side of the cleaning machine main body 1; a wireless/limited communication module is arranged in the electric cabinet 5 and is electrically connected with the hand-held remote controller; and further, the remote control operation of the cleaning machine is realized through the mutual communication between the wireless or wired communication module and the handheld remote controller. Meanwhile, the camera or radar device is further arranged on the cleaner body 1 so as to realize autonomous navigation of the device and facilitate full-automatic operation of the cleaning machine.

The upper side of the cleaner body 1 is also provided with a water tank 2, the top of the water tank 2 is provided with a water filling port 3, and the front side of the water tank 2, which corresponds to the cleaning head 11, is also provided with a spray head 4. Therefore, water or cleaning liquid is injected into the water tank 2 through the water injection port 3, and the cleaning liquid is sprayed to the ground to be cleaned by utilizing the spray head 4 positioned at the same end with the cleaning head 11, so that the aim of assisting cleaning is fulfilled.

Four groups of travelling wheels are arranged on the lower side of the cleaner body 1, and the four groups of travelling wheels are divided into two groups of cleaning end travelling wheels 7 positioned on one side where the cleaning head 11 is arranged and two groups of non-cleaning end travelling wheels 6 positioned on the other side; and, each group of non-cleaning end travelling wheels 6 and cleaning end travelling wheels 7 are respectively provided with an independent travelling motor 8, and the travelling motors 8 are also respectively connected with the lower side of the cleaner body 1 through connecting frames (as shown in fig. 1). According to specific use needs, the travelling wheels can adopt Mecanum wheels, omni wheels or common wheels so as to realize the travelling and steering of the cleaning machine. For example: when the Mecanum wheel is used, the cleaning machine is driven to run straight through the same-speed rotation of the four groups of running motors 8, and the cleaning machine is driven to turn by utilizing the differential rotation of the groups of running motors 8 on different sides; the transverse movement of the cleaning machine is realized by the reverse constant-speed rotation of the traveling motor 8 of the two groups of cleaning end traveling wheels 7 and the traveling motor 8 of the two groups of non-cleaning end traveling wheels 6.

The design principle of the Mecanum wheel is that rollers which are arranged at an angle of 45 degrees with the axle center are arranged in an outer ring of the wheel to contact with the ground, and when the Mecanum wheel rotates, friction force can generate a reverse thrust which is 45 degrees with the axle, and the reverse thrust can be divided into a longitudinal vector and a transverse vector. The whole floor cleaning machine is driven by two pairs of Mecanum wheels with mirror image arrangement of rollers, each wheel can generate corresponding vectors, and the resultant force of the vectors determines the final activity state of the vehicle body; by adjusting the independent steering and rotating speed of each wheel, the whole vehicle body can move forwards, transversely move, incline, rotate and the combination thereof.

The cleaner body 1 has a cleaning head 11 at one end, the cleaning head 11 is provided at the end of the cleaner body 1 so as to be swingable up and down, and a cleaning head tip 12 is provided at a portion of the cleaning head 11 which contacts the floor surface. The cleaning head end 12 can be a brush or a rag, or a scraper made of flexible materials, so as to improve the friction between the cleaning head 11 and the floor, clean the floor by using the cleaning head end 12 with cleaning function, and facilitate the cleaning and replacement of the cleaning head end 12. At the same time, after the cleaning head 11 has been swung down, the cleaning head end 12 can be pressed against the floor 14 and a certain contact pressure can be ensured. Further, in the cleaning state of the cleaning machine, the cleaning head 11 is swung down, the cleaning head tip 12 is pressed against the floor 14, and the floor is cleaned in a sliding and translating manner as the cleaning machine travels. Moreover, in the moving state of the cleaning machine, the cleaning head 11 is lifted upward to disengage the cleaning head tip 12 from the floor 14, so that the walking of the cleaning machine and the adjustment of the position angle are facilitated. In addition, depending on the particular application requirements, the cleaning end road wheels 7 may be lifted off the floor (as shown in fig. 5) in order to ensure pressure between the cleaning head tip 12 and the floor 14; at this point, about half of the total cleaning machine weight is pressed against the cleaning head 11 and the cleaning head end 12, thereby ensuring that sufficient friction is created between the cleaning head end 12 and the floor 14 during movement of the cleaning machine to promote cleaning.

The cleaning head 11 is of a strip-shaped structure, and swing arms 10 are respectively arranged at two ends of the strip-shaped cleaning head 11; the lower end of the swing arm 10 is connected to the cleaning head 11, and the upper end of the swing arm 10 is connected to the driving end of the swing driving device provided at the lower side of the cleaner body 1. The swing driving device can adopt a swing motor 9, the swing motor 9 is connected with the lower side of the end part of the cleaner body 1 through a motor connecting frame 13, and the output end of the swing motor 9 is connected with the upper end of a swing arm 10. It is understood that the swing motor 9 may be a direct-driven torque motor or a gear motor with a speed reducer, or a general rotary motor or a linear motor may be used. The swing motor 9 is used for realizing the up-and-down swing of the swing arm 10, so that the long-strip-shaped cleaning head 11 is driven to lift or swing down, the action range of the swing arm 10 is ensured, the tail end 12 of the cleaning head 11 can swing down and contact the ground 14, and can lift and leave the ground 14, so that the moving state and the cleaning state of the cleaning machine can be switched. Meanwhile, the swing driving device can also adopt an electromagnetic adsorption mechanism, and can realize adsorption or release of the swing arm 10 by powering on or powering off, so that the up-and-down swing of the swing arm 10 is controlled by the electromagnetic adsorption mechanism.

When the floor cleaning machine is used, firstly, the swing motor 9 drives the swing arm 10 to swing upwards, so that the cleaning head 11 and the cleaning head tail end 12 thereon are lifted upwards and separated from the floor 14 (as shown in fig. 1 and 2), at this time, the non-cleaning end travelling wheel 6 and the cleaning end travelling wheel 7 which are arranged at the lower side of the cleaning machine body 1 in front and back are contacted with the floor 14, namely: the cleaning machine is in a mobile state. In addition, since the cleaning head end 12 in the moving state does not contact the floor, the cleaning machine can flexibly adjust its own position and posture angle, thereby swinging the cleaning head end 12 downward in the most reasonable position and angle state and opening the cleaning state. When cleaning of the floor is required, the swing motor 9 drives the swing arm 10 to swing downwards, thereby swinging the cleaning head 11 down and pressing the cleaning head end 12 against the floor 14.

Then, the cleaning machine in a cleaning state (the cleaning head tip 12 of the lower swing is in contact with the floor 14) performs walking by the driving of the walking wheels on the cleaning machine body 1, so that the floor is cleaned in a sliding and translating manner by the cleaning head tip 12 having a cleaning function. It can be understood that when the front cleaning end traveling wheel 7 is lifted off the floor 14, the cleaning machine is driven by the two sets of non-cleaning end traveling wheels 6 contacting the floor 14 at the rear end of the cleaning machine body 1 (as shown in fig. 5). In the process of machine cleaning and walking, the spray head 4 arranged at the front side of the water tank 2 can be used for spraying cleaning liquid to the ground to be cleaned, so as to achieve the aim of assisting cleaning. Meanwhile, in the cleaning state, if the cleaning machine encounters obstacles such as walls and furniture, the cleaning machine can be switched back to a moving state, and the position and posture of a vehicle body or the direction change of the vehicle body are adjusted by utilizing the flexible movement and steering capability of the Mecanum wheels, so that ground dirt is erased from different angles. And, since only one forward side of the cleaner head end 12 contacts dirt, no secondary pollution is caused to the floor surface which has been cleaned.

In addition, in the cleaning process, if the cleaned floor is met or the floor which is not cleaned originally is cleaned, the cleaning head 11 can be lifted and switched to a moving state, so that secondary pollution to the cleaned floor is avoided, and the cleaning efficiency is improved. In addition, if the ground surface of the small local area only has dirt to be cleaned, the ground surface can be cleaned by moving the ground surface to the area, and the ground surface leaves the area in a moving state after the cleaning is finished, so that the influence on other ground surfaces which do not need to be cleaned can be avoided, and the cleaning efficiency is further improved. If the cleaning machine encounters a tough dirt which cannot be cleaned once, the cleaning machine can be switched to a moving state again, and then is switched to a cleaning state again and moves forward for cleaning, so that the cleaning machine can clean reciprocally. Finally, when various garbage and dirt are erased and collected together, the cleaning machine can push the garbage and dirt into the garbage container such as a dustpan, a dustpan and the like in a cleaning state.
