Fig. 1 shows an embodiment of the floor-finishing robot of the invention, comprising a frame 10, 4 trowel disc mechanisms 20, 4 oscillating drive mechanisms 30 and a rotary drive mechanism 40. Wherein, 4 wipe set of mechanism 20 and be the square array setting in frame 10, 4 swing actuating mechanism 30 set up on frame 10 to with 4 wipe set of mechanism 20 drive connection respectively, rotary driving mechanism 40 and 4 wipe set of mechanism 20 drive connection respectively. In the use process, the swing driving mechanism 30 drives the swabbing mechanism 20 to swing, and the rotary driving mechanism 40 drives the swabbing mechanism 20 to rotate.

By applying the technical scheme of the invention, the angles between the 4 plastering plate mechanisms 20 and the ground can be respectively changed, so that the operation of the ground plastering robot has higher motion flexibility compared with the prior double-disc ground plastering robot, and the plastering effect is better than that of the prior double-disc ground plastering robot.

Before explaining the advantages of the floor-finishing robot of the present invention, reference may be made to the patent application with publication number CN 110158964 a regarding the motion principle of the double-disc floor-finishing robot. The floor finishing robot adopting the invention has the following specific advantages:

as shown in fig. 3, the floor finishing robot of the present embodiment may move in a traceless walking mode, in which the 2 troweling mechanisms 20 controlling the first side a1 of the 4 sides of the square array are disposed at an angle with respect to the floor, the 2 troweling mechanisms 20 controlling the second side a2 of the 4 sides of the square array are disposed in parallel with respect to the floor, and the 2 troweling mechanisms 20 of the first side a1 drive the 2 troweling mechanisms 20 of the second side a2 to move toward the front side of the first side a 1. In this movement mode, although the concrete floor can be smoothed when the 2 troweling mechanisms 20 of the first side a1 travel with the floor-smoothing robot, the edge of the 2 troweling mechanisms 20 of the first side a1 easily leaves a certain trace of work on the floor because the 2 troweling mechanisms 20 of the first side a1 have a certain angle with the floor. At this time, the second work of the 2 plastering plate mechanisms 20 on the second side a2 can remove the work traces left on the ground by the 2 plastering plate mechanisms 20 on the first side a1, thereby playing the role of walking without traces and improving the plastering effect.

In fig. 3, the first side a1 is the upper side of the 4 sides in the square array, and the second side a2 is the lower side of the 4 sides in the square array, so that the floor finishing robot can travel upward. As another alternative embodiment, the first side a1 may be the left side of the 4 sides in the square array, and the second side a2 may be the right side of the 4 sides in the square array, which may enable the floor-finishing robot to walk to the left. Similarly, the floor-finishing robot can walk to the right and walk downwards according to the difference defined by the first side a1 and the second side a2, so that the floor-finishing robot has higher motion flexibility.

As shown in fig. 4, the floor finishing robot of the present embodiment may adopt a four-wheel drive walking mode, in which the 2 troweling mechanisms 20 controlling the first side a1 of the 4 sides of the square array are disposed at an angle with respect to the floor, the 2 troweling mechanisms 20 controlling the second side a2 of the 4 sides of the square array are disposed at an angle with respect to the floor, and the 2 troweling mechanisms 20 of the first side a1 and the 2 troweling mechanisms 20 of the second side a2 are moved toward the front side of the first side a1 together. In this movement mode, the 2 troweling mechanisms 20 on the first side a1 and the 2 troweling mechanisms 20 on the second side a2 can drive the floor surface troweling robot to move towards the front side of the first side a1 together, and when the floor surface troweling robot is driven to move, the driving force is increased, and the operation power of the floor surface troweling robot is increased. Although the traveling power of the floor surface finishing robot is increased in this mode, the floor surface is also marked with some traveling traces as in the case of the double-disc floor surface finishing robot, but since the 2 troweling plate mechanisms 20 of the second side a2 correspond to the secondary construction of the double-disc floor surface finishing robot, the problem of the traveling traces is improved as compared with the double-disc floor surface finishing robot.

In fig. 4, in the four-wheel drive traveling mode, the first side a1 is the upper side of the 4 sides in the square array, and the second side a2 is the lower side of the 4 sides in the square array, so that the floor finishing robot can travel upward. As another alternative embodiment, in the four-wheel drive walking mode, the first side a1 may be the left side of the 4 sides in the square array, and the second side a2 may be the right side of the 4 sides in the square array, which may enable the floor-finishing robot to walk to the left. Similarly, the floor plastering robot can realize walking towards the right and walking towards the lower according to the difference defined by the first side a1 and the second side a2 in the four-wheel drive walking mode, so that the floor plastering robot has higher motion flexibility.

As shown in fig. 5, the floor finishing robot of this embodiment may adopt a traceless rotation mode, in the traceless rotation mode, the 2 roulette mechanisms 20 controlling the first diagonal c1 in the 2 diagonals of the square array are disposed at an angle with respect to the ground, the 2 roulette mechanisms 20 controlling the second diagonal c2 in the 2 diagonals of the square array are disposed in parallel with respect to the ground, and the 2 roulette mechanisms 20 of the first diagonal c1 drive the 2 roulette mechanisms 20 of the second diagonal c2 to rotate clockwise or counterclockwise. When the traditional double-disc type floor polishing robot rotates, because 2 disc cleaning mechanisms still have certain angles relative to a horizontal plane, certain working marks can be easily left on the floor by the edge of the disc cleaning mechanism. By adopting the technical scheme of the embodiment, the 2 troweling mechanisms 20 of the first diagonal c1 are arranged at an angle relative to the ground, so that the ground polishing robot can be driven to rotate, and the 2 troweling mechanisms 20 of the second diagonal c2 are arranged in parallel relative to the ground, so that the leveling traces left on the ground by the 2 troweling mechanisms 20 of the first diagonal c1 can be eliminated, and the effect of seamless rotation is achieved. More preferably, the floor plastering robot should rotate around the center of the first diagonal line c1, so as to achieve better effect of eliminating the rotation mark.

In the above-described embodiment, the first diagonal line c1 may be defined as a diagonal line at the position shown in the drawing, or may be defined as a diagonal line at another position in the drawing as another alternative embodiment.

As shown in fig. 6, the floor finishing robot of the present embodiment may adopt a four-wheel drive rotation mode, in which 2 of the roulette mechanisms 20 controlling the first diagonal line c1 of the 2 diagonal lines of the square array are disposed at an angle with respect to the ground, and 2 of the roulette mechanisms 20 controlling the second diagonal line c2 of the 2 diagonal lines of the square array are disposed at an angle with respect to the ground, so that the 2 of the roulette mechanisms 20 of the first diagonal line c1 and the 2 of the roulette mechanisms 20 of the second diagonal line c2 rotate together clockwise or counterclockwise. In the four-wheel drive rotation mode, the 2 swabbing mechanisms 20 of the first diagonal line c1 and the 2 swabbing mechanisms 20 of the second diagonal line c2 can both act on the ground, so that the driving force is improved, and the running power of the ground surface trowelling robot is improved. Although the rotation power of the floor surface finishing robot is increased in this mode, the floor surface is also marked with some walking traces as in the case of the double-disc floor surface finishing robot, but since the 2 troweling plate mechanisms 20 of the second diagonal line c2 correspond to the secondary construction of the double-disc floor surface finishing robot, the problem of the rotation traces is improved as compared with the double-disc floor surface finishing robot.

In the technical solution of the present invention, in order to achieve higher movement flexibility of the floor surface troweling robot, the 4 troweling plate mechanisms 20 are mechanisms with the same structure or slightly different structures.

Preferably, in the technical solution of the present embodiment, the radius of gyration of each trowel mechanism 20 is equal, so as to achieve higher motion flexibility of the floor-finishing robot.

In the technical solution of this embodiment, as shown in fig. 1 and fig. 2, there are 4 rotation driving mechanisms 40, and 1 rotation driving mechanism 40 is correspondingly connected to 1 spatula mechanism 20 in a driving manner, so that the 4 rotation driving mechanisms 40 can be controlled to realize relatively independent clockwise rotation or counterclockwise rotation according to different motion requirements. Thereby accommodating the movement of the first side a1 and the second side a2 based on different definitions in the traceless walking mode and the four-wheel drive walking mode described above. Preferably, in the present embodiment, the rotary drive mechanism 40 is directly attached to the spatula mechanism 20.

As another optional embodiment not shown in the drawings, there are two rotary driving mechanisms 40, and 1 rotary driving mechanism 40 is in driving connection with 2 plastering plate mechanisms 20, and the other 1 rotary driving mechanism 40 is in driving connection with the other 2 plastering plate mechanisms 20. This embodiment is slightly inferior to the above embodiment in terms of the movement flexibility of the floor finishing robot, but the cost is reduced compared to the above embodiment. In addition, as other alternative embodiments, 1 rotation driving mechanism 40 is also possible, which falls within the scope of the present invention.

It should be noted that, for a specific implementation of the swing driving mechanism 30 for driving the aforementioned swabbing mechanism 20 to swing, reference may be made to the patent application with application publication No. CN 212534968U, and since the protection direction mainly related to the present invention does not relate to how to drive the swabbing mechanism 20 to swing, but relates to a higher motion flexibility and a better light wiping effect of the floor surface finishing robot with the 4-swabbing mechanism, how to implement the swinging of the swabbing mechanism 20 is not described in detail herein.

The invention also provides a control method of the floor polishing robot, which is used for controlling the floor polishing robot and comprises a traceless walking mode, wherein in the traceless walking mode, 2 plate coating mechanisms 20 of a first side a1 of 4 sides of the square array are controlled to be arranged at an angle relative to the ground, 2 plate coating mechanisms 20 of a second side a2 of the 4 sides of the square array are controlled to be arranged in parallel relative to the ground, and the 2 plate coating mechanisms 20 of the first side a1 drive the 2 plate coating mechanisms 20 of the second side a2 to move towards the front side of the first side a 1. In this movement mode, although the concrete floor can be smoothed when the 2 troweling mechanisms 20 of the first side a1 travel with the floor-smoothing robot, the edge of the 2 troweling mechanisms 20 of the first side a1 easily leaves a certain trace of work on the floor because the 2 troweling mechanisms 20 of the first side a1 have a certain angle with the floor. At this time, the second work of the 2 plastering plate mechanisms 20 on the second side a2 can remove the work traces left on the ground by the 2 plastering plate mechanisms 20 on the first side a1, thereby playing the role of walking without traces and improving the plastering effect.

In fig. 3, the first side a1 is the upper side of the 4 sides in the square array, and the second side a2 is the lower side of the 4 sides in the square array, so that the floor finishing robot can travel upward. As another alternative embodiment, the first side a1 may be the left side of the 4 sides in the square array, and the second side a2 may be the right side of the 4 sides in the square array, which may enable the floor-finishing robot to walk to the left. Similarly, the floor-finishing robot can walk to the right and walk downwards according to the difference defined by the first side a1 and the second side a2, so that the floor-finishing robot has higher motion flexibility.

Specifically, in the non-trace rotation mode in the present embodiment, in the non-trace travel mode, the 2 wiper mechanisms 20 of the first side a1 rotate toward each other, the 2 wiper mechanisms 20 of the first side a1 are inclined toward the relatively close inner side, and the movement direction of the relatively close inner side of the 2 wiper mechanisms 20 of the first side a1 is opposite to the movement direction of the front side of the first side a 1.

As shown in fig. 5, the control method further includes a non-trace rotation mode, in which the 2 roulette mechanisms 20 controlling the first diagonal line c1 of the 2 diagonal lines of the square array are disposed at an angle with respect to the ground, and the 2 roulette mechanisms 20 controlling the second diagonal line c2 of the 2 diagonal lines of the square array are disposed in parallel with respect to the ground, so that the 2 roulette mechanisms 20 of the first diagonal line c1 drive the 2 roulette mechanisms 20 of the second diagonal line c2 to rotate clockwise or counterclockwise. When the traditional double-disc type floor polishing robot rotates, because 2 disc cleaning mechanisms still have certain angles relative to a horizontal plane, certain working marks can be easily left on the floor by the edge of the disc cleaning mechanism. By adopting the technical scheme of the embodiment, the 2 troweling mechanisms 20 of the first diagonal c1 are arranged at an angle relative to the ground, so that the ground polishing robot can be driven to rotate, and the 2 troweling mechanisms 20 of the second diagonal c2 are arranged in parallel relative to the ground, so that the leveling traces left on the ground by the 2 troweling mechanisms 20 of the first diagonal c1 can be eliminated, and the effect of seamless rotation is achieved. More preferably, the floor plastering robot should rotate around the center of the first diagonal line c1, so as to achieve better effect of eliminating the rotation mark.

In the above-described embodiment, the first diagonal line c1 may be defined as a diagonal line at the position shown in the drawing, or may be defined as a diagonal line at another position in the drawing as another alternative embodiment.

Specifically, in the present embodiment, in the traceless rotation mode, the 2 swabbing mechanisms 20 of the first diagonal c1 rotate in opposite directions, and the 2 swabbing mechanisms 20 of the first diagonal c1 are all inclined toward the first end of the first diagonal c1, so that counterclockwise rotation is achieved. In addition, the 2 swabbing mechanisms 20 of the first diagonal c1 can be inclined towards the second end of the first diagonal c1, so as to realize clockwise rotation.

As shown in fig. 4, the control method further includes a four-drive traveling mode in which the 2 roulette mechanisms 20 controlling the first side a1 of the 4 sides of the square array are disposed at an angle with respect to the ground, the 2 roulette mechanisms 20 controlling the second side a2 of the 4 sides of the square array are disposed at an angle with respect to the ground, and the 2 roulette mechanisms 20 of the first side a1 and the 2 roulette mechanisms 20 of the second side a2 are moved toward the front side of the first side a1 together. In this movement mode, the 2 troweling mechanisms 20 on the first side a1 and the 2 troweling mechanisms 20 on the second side a2 can drive the floor surface troweling robot to move towards the front side of the first side a1 together, and when the floor surface troweling robot is driven to move, the driving force is increased, and the operation power of the floor surface troweling robot is increased. Although the traveling power of the floor surface finishing robot is increased in this mode, the floor surface is also marked with some traveling traces as in the case of the double-disc floor surface finishing robot, but since the 2 troweling plate mechanisms 20 of the second side a2 correspond to the secondary construction of the double-disc floor surface finishing robot, the problem of the traveling traces is improved as compared with the double-disc floor surface finishing robot.

In fig. 4, in the four-wheel drive traveling mode, the first side a1 is the upper side of the 4 sides in the square array, and the second side a2 is the lower side of the 4 sides in the square array, so that the floor finishing robot can travel upward. As another alternative embodiment, in the four-wheel drive walking mode, the first side a1 may be the left side of the 4 sides in the square array, and the second side a2 may be the right side of the 4 sides in the square array, which may enable the floor-finishing robot to walk to the left. Similarly, the floor plastering robot can realize walking towards the right and walking towards the lower according to the difference defined by the first side a1 and the second side a2 in the four-wheel drive walking mode, so that the floor plastering robot has higher motion flexibility.

Specifically, in the embodiment, as shown in fig. 4, in the four-wheel drive traveling mode, the 2 wiper mechanisms 20 of the first side a1 rotate toward each other, the 2 wiper mechanisms 20 of the first side a1 are inclined toward the relatively close inner side, and the movement direction of the relatively close inner side of the 2 wiper mechanisms 20 of the first side a1 is opposite to the movement direction of the front side of the first side a 1. At the same time, the 2 swabbing mechanisms 20 of the second side a2 rotate towards each other, the 2 swabbing mechanisms 20 of the second side a2 incline towards the relatively close inner side, and the movement direction of the relatively close inner side of the 2 swabbing mechanisms 20 of the second side a2 is opposite to the movement direction of the front side of the second side a 2. Therefore, the ground finishing robot can walk under four drives.

As shown in fig. 6, the control method further includes a four-wheel drive rotation mode, in which 2 of the roulette mechanisms 20 controlling the first diagonal line c1 of the 2 diagonal lines of the square array are disposed at an angle with respect to the ground, and 2 of the roulette mechanisms 20 controlling the second diagonal line c2 of the 2 diagonal lines of the square array are disposed at an angle with respect to the ground, so that the 2 of the roulette mechanisms 20 of the first diagonal line c1 and the 2 of the roulette mechanisms 20 of the second diagonal line c2 are rotated clockwise or counterclockwise together. In the four-wheel drive rotation mode, the 2 swabbing mechanisms 20 of the first diagonal line c1 and the 2 swabbing mechanisms 20 of the second diagonal line c2 can both act on the ground, so that the driving force is improved, and the running power of the ground surface trowelling robot is improved. Although the rotation power of the floor surface finishing robot is increased in this mode, the floor surface is also marked with some walking traces as in the case of the double-disc floor surface finishing robot, but since the 2 troweling plate mechanisms 20 of the second diagonal line c2 correspond to the secondary construction of the double-disc floor surface finishing robot, the problem of the rotation traces is improved as compared with the double-disc floor surface finishing robot.

Specifically, in the technical solution of the present embodiment, as shown in fig. 6, in the four-wheel drive rotation mode, 2 swabbing mechanisms 20 of the first diagonal line c1 rotate oppositely, 2 swabbing mechanisms 20 of the second diagonal line c2 rotate oppositely, 2 swabbing mechanisms 20 of the first diagonal line c1 are all inclined towards the first end of the first diagonal line c1, and 2 swabbing mechanisms 20 of the second diagonal line c2 are all inclined towards the first end of the first diagonal line c1, so that the counterclockwise rotation under the four-wheel drive is realized. In addition, it is also possible to incline the 2 swashplate mechanisms 20 of the first diagonal c1 to the second end of the first diagonal c1, and incline the 2 swashplate mechanisms 20 of the second diagonal c2 to the second end of the first diagonal c1, thereby achieving clockwise rotation under four-wheel drive.

The relative arrangement of the components and steps, the numerical expressions and numerical values set forth in these embodiments do not limit the scope of the present invention unless specifically stated otherwise. Meanwhile, it should be understood that the sizes of the respective portions shown in the drawings are not drawn in an actual proportional relationship for the convenience of description. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate. In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
