Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of floor sweepers, and particularly relates to a rag bracket capable of reducing the slipping of a floor-sweeping robot during mopping. Background Art
[0002] When a floor-sweeping robot cleans a home environment, a rag plays a role in mopping the floor. The rag is usually made of cloth and needs to be attached to a specific rag bracket to complete the mopping work. And for a good mopping effect, the rag needs to have an interference contact friction with the ground as much as possible over the largest area.
[0003] Due to this rigid requirement above, it forms an obstacle to the floor-sweeping machine during its movement. For example, when on a carpet, crossing a threshold, or crossing obstacles such as slippers, a triangle is formed between the front end / tail end of the floor-sweeping machine and the ground. Since the driving mechanism of the floor-sweeping machine is located in the middle of the floor-sweeping machine, when a triangle is formed, the driving wheels extend out to contact the ground, and the spring force acting on the friction between the driving wheels and the ground decreases. At this time, the driving wheels are prone to slipping, directly causing the floor-sweeping machine to spin in place and unable to move forward. Summary of the Utility Model
[0004] The utility model provides a rag bracket capable of reducing the slipping of a floor-sweeping robot during mopping, which solves the problems in the prior art.
[0005] The technical solution of the utility model is realized as follows:
[0006] A rag bracket capable of reducing the slipping of a floor-sweeping robot during mopping includes a floor-sweeping machine, driving wheels located below the floor-sweeping machine, and a rag bracket is further arranged along the tail end of the floor-sweeping machine. A rag is also attached to the lower end face of the rag bracket;
[0007] The tail end of the rag bracket is integrally provided with an inclined plane facing backward and upward, and an auxiliary member is also installed on the inclined plane;
[0008] When the floor-sweeping machine travels flat, the auxiliary member is in a suspended state and does not contact the floor;
[0009] When the front end of the floor-sweeping machine crosses an obstacle, the auxiliary member at the tail end of the floor-sweeping machine inclines towards the floor and contacts it, the rag is lifted and does not contact the floor, and the driving wheels are ejected to contact the floor.
[0010] Further, the inclined plane is a flat inclined plane or an arc-shaped inclined plane.
[0011] Further, a connecting frame is integrally formed at the tail of the rag bracket, and avoidance positions are also provided at the corresponding positions of the rag, the connecting frame, and the auxiliary member.
[0012] Further, the auxiliary member is an auxiliary wheel.
[0013] Further, a rotating shaft is fixedly and penetratingly arranged at the axis of the auxiliary wheel, and the rotating shaft is movably installed inside the connecting frame.
[0014] Further, the auxiliary member is an auxiliary block.
[0015] Further, the contact surface between the auxiliary block and the floor is arc-shaped.
[0016] Further, a universal wheel is also arranged at the front end of the sweeper, which is used to assist the steering of the sweeper.
[0017] Further, a buckle column and an elastic column are fixedly installed at the upper end of the rag. The buckle column and the elastic column form a complete cylinder. A clamping ring is also formed on the outer periphery of the upper end of the elastic column. A buckle hole is also opened on the lower end surface of the sweeper. The buckle column and the elastic column can be inserted into the buckle hole, and the buckle column and the elastic column are fixed in the buckle hole through the clamping ring.
[0018] After adopting the above technical solution, the beneficial effects of the present utility model are:
[0019] 1. In the present utility model, by providing an auxiliary member, when the sweeper crosses an obstacle, the rag bracket and the rag arranged at its bottom end are lifted and do not contact the floor. At this time, the auxiliary member contacts the floor, reducing the frictional resistance with the floor. And by ejecting the driving wheel to contact the floor, it can help the sweeper turn over the obstacle, thus avoiding the situation of the driving wheel idling.
[0020] 2. In the present utility model, by arranging the auxiliary member on the inclined plane at the rear upper part of the tail of the rag bracket, when the sweeper travels along a plane, the auxiliary member is in a suspended state due to its installation position and does not contact the floor, so that the rag on the sweeper can still contact and rub the floor with the largest area in an interference manner.
[0021] 3. In the present utility model, by providing a buckle column and an elastic column, it is convenient to be fixedly installed in the buckle hole, which is convenient for the disassembly of the rag bracket and the rag. Description of the Drawings

Detailed implementation mode
[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0035] Embodiment 1: As Figure 1-10 shown, a rag holder that can reduce the slipping of the floor mopping of a floor sweeping robot includes a floor sweeper 10, a driving wheel 13 located below the floor sweeper 10 for driving the floor sweeper 10 to move forward or backward, and a rag holder 11 is further provided along the tail end of the floor sweeper 10. A rag 12 is also attached to the lower end face of the rag holder 11;
[0036] The end of the rag support 11 is also integrally provided with an inclined surface 11a that slopes backward and upward, and an auxiliary member is also installed on the inclined surface 11a;
[0037] When the floor sweeper 10 travels flat, the auxiliary member is in a suspended state and does not contact the floor;
[0038] The inclined surface 11a is a flat inclined surface or an inclined arc surface;
[0039] An elastic member (not shown in the figure) is also provided inside the floor sweeper 10. The driving wheel 13 and the elastic member cooperate with each other, and the elastic member can drive the driving wheel 13 downward to contact the floor; a universal wheel 14 is also rotatably provided at the front end of the floor sweeper 10; the auxiliary member at the end of the rag support 11 inclines toward the floor and contacts it. Among them, the cooperation between the driving wheel 13 and the elastic member is a structure in an existing floor sweeper, so it will not be described in detail in the specification and the accompanying drawings of the specification;
[0040] As Figure 1-3 shown, when the floor sweeper 10 crosses an obstacle on the floor, the universal wheel 14 at the front end of the floor sweeper 10 first contacts the obstacle at this time, and the rag support 11 at the tail of the floor sweeper 10 together with the rag 12 is lifted to the state as Figure 3 shown. At this time, the rag 12 does not contact the floor, reducing the friction between the floor sweeper 10 and the floor. When the floor sweeper 10 is lifted, the elastic member forces the driving wheel 13 to contact the floor downward. Since the friction resistance between the front floor sweeper 10 and the floor is reduced, the driving wheel 13 can easily drive the floor sweeper 10 to cross the obstacle, avoiding the phenomenon of idling;
[0041] Among them, as Figure 5-6 shown, a connecting frame 112 is integrally formed at the tail of the rag support 11. The rag 12 is also provided with a relief position 121 at the corresponding position of the connecting frame 112 and the auxiliary member. The auxiliary member is an auxiliary wheel 111, and a rotating shaft 113 is fixedly penetrated through the center of the auxiliary wheel 111, and the rotating shaft 113 is movably installed inside the connecting frame 112;
[0042] When the floor sweeper 10 moves on a flat floor, the auxiliary wheel 111 does not contact the floor, avoiding affecting the movement of the floor sweeper 10 in the normal state. When the floor sweeper 10 crosses an obstacle, the front end of the floor sweeper 10 is lifted. At this time, the auxiliary wheel 111 at the tail of the rag support 11 contacts the floor, and through the sliding of the auxiliary wheel 111, it is convenient for the floor sweeper 10 to cross the obstacle forward;
[0043] Embodiment 2: As Figure 7 shown, the difference from Embodiment 1 is that the auxiliary member is an auxiliary block 114; the contact surface between the auxiliary block 114 and the floor is arc-shaped;
[0044] Embodiment 3: The difference from Embodiment 1 and Embodiment 2 is that, as Figure 8-9 shown, a snap post 122 and an elastic post 123 are also fixedly installed at the upper end of the cleaning cloth 12. The snap post 122 and the elastic post 123 can form a complete cylinder. A snap ring is further formed on the outer periphery of the upper end of the elastic post 123. A snap hole 101 is also formed on the lower end surface of the floor sweeper 10. The snap post 122 and the elastic post 123 can be inserted into the snap hole 101. The snap post 122 and the elastic post 123 inserted into the snap hole 101 are forced to close into a cylinder. Since the elastic post 123 has an outward elastic resistance and a snap ring is also provided on the elastic post 123, the elastic post 123 and the snap post 122 can be fixed in the snap hole 101. And by pressing the elastic post 123 to make a fine-tuning deformation towards the snap post 122, the elastic post 123 and the snap post 122 can be taken out from the snap hole 101, which is convenient for removing the cleaning cloth bracket 11 and the cleaning cloth 12 from the floor sweeper 10.
[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
