mopping robot

Abstract

The present invention belongs to the field of household electrical appliances, and particularly relates to a mopping robot comprising a mopping machine and a base station. The mopping machine is provided with tires, and the base station has a running surface for the mopping machine to enter the base station. The tire tread is provided with a plurality of first ribs, spaced circumferentially along the tire; the running surface is provided with a plurality of second ribs, spaced sequentially along the mopping machine's travel direction, with grooves for the first ribs to be inserted into the running surface formed between adjacent second ribs. When the mopping robot is moving, the first ribs on the tire fall between the second ribs on the running surface. The rotation of the tire causes the first ribs to directly act on the second ribs on the running surface, thereby converting the friction between the tire and the running surface into thrust, propelling the mopping machine into the base station. This significantly improves the reliability of the mopping machine entering the base station, thereby enhancing the mopping machine's anti-slip performance.

Among them, mopping robots are one of the intelligent household appliances. Mopping robots can automatically complete cleaning work, greatly reducing people's work in home cleaning.

[0003] The existing mopping robot includes a mopping machine and a base station. After completing a period of cleaning work, the mopping machine returns to the base station, and the base station automatically cleans the wiping cloth on the mopping machine, thereby solving the trouble of people manually cleaning the wiping cloth. During the mopping process, the mopping machine needs to return to the base station to clean the wiping cloth. When the mopping machine enters and exits the base station, water or detergent on the wiping cloth will drip onto the walking surface of the mopping robot entering the base station, making the walking surface extremely slippery. As a result, when the mopping machine moves on the walking surface, the tires of the mopping machine will slip and it will be unable to enter the base station smoothly. Summary of the Invention

[0013] The tire has a symmetry plane perpendicular to the axial direction of the tire. The first inclined section and the second inclined section are respectively arranged on both sides of the symmetry plane and extend obliquely towards each other in a direction away from the symmetry plane.

[0014] Optionally, the distance between the first straight line segment and the second straight line segment is greater than or equal to the width of the second rib.

When the walking surface is wet and slippery, the first rib falls into the groove, so that the tire of the mopping robot will not slip, and then it can smoothly enter the base station.

Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0032] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0033] like Figures 1 to 6 As shown, in one embodiment of the present invention, a mopping robot is provided, including a mopping machine 10 and a base station 20, wherein a wiping cloth is provided at the bottom of the mopping machine 10, and when the mopping machine 10 moves, the wiping cloth contacts the ground, thereby wiping the ground and completing the mopping function; in addition, when the wiping cloth needs to be cleaned, the mopping machine 10 will return to the base station 20, and the cleaning component in the base station 20 will clean the wiping cloth. After cleaning, the mopping machine 10 moves out of the base station 20 and continues to mop the ground.

[0034] Specifically, the mopping machine 10 is provided with a tire 11, and the mopping machine 10 is provided with a walking wheel hub. The tire 11 is installed on the walking wheel hub. By driving the rotation of the walking wheel roller, the tire 11 is driven to rotate, thereby realizing the walking function. Among them, tires 11 are provided on the left and right sides of the bottom of the mopping machine 10, so that both sides of the mopping machine 10 have supporting walking power, and the walking of the mopping machine 10 is more stable and reliable.

[0035] Furthermore, the base station 20 has a walking surface 21 for the mopping machine 10 to enter the base station 20. Figure 1 、 Figure 4 and Figure 5 As shown, the walking surface 21 is set on the bottom plate 22 of the base station 20; a plurality of first ribs 111 are provided on the tread of the tire 11, and the first ribs 111 are arranged at intervals along the circumference of the tire 11; the walking surface 21 is provided with a plurality of second ribs 211, and the second ribs 211 are arranged in sequence at intervals along the walking direction of the mopping machine 10, and a groove 212 for inserting the first rib 111 is formed between two adjacent second ribs 211.

[0036] In the mopping robot of the embodiment of the present application, when the wiping cloth needs to be cleaned, the mopping robot 10 enters the base station 20 along the walking surface 21. During this process, the first rib 111 on the tire 11 falls between two adjacent second ribs 211 on the walking surface 21, that is, the first rib 111 falls into the groove 212 on the walking surface 21. In this way, the tire 11 rotates, causing the first rib 111 to squeeze the second rib 211, that is, the first rib 112 directly acts on the second rib 211 of the walking surface 21, thereby converting the friction between the tire 11 and the walking surface 21 into thrust, pushing the mopping robot 10 into the base station 20, greatly improving the reliability of the mopping robot 10 entering the base station 20, that is, improving the anti-slip performance of the mopping robot 10. When the walking surface 21 is slippery, the first rib 111 falls into the groove 212, so that the tire 11 of the mopping robot 10 will not slip, and then smoothly enter the base station 20.

[0037] It should be noted that, see Figure 4 As shown, two groups of second ribs 211 are provided on the walking surface 21, and the two tires 11 enter the base station 20 along the two groups of second ribs 211 respectively. This ensures that both tires 11 of the mopping machine 10 will not slip, thereby smoothly entering the base station 20.

[0038] In another embodiment of the present invention, see Figure 4 and Figure 6 As shown, the spacing L1 between two adjacent second ribs 211 of the mopping robot is greater than or equal to the width L2 of the first rib 111. This allows the first rib 111 to completely fit between the second ribs 211 during travel, making it difficult for the first rib 111 to slip out. This prevents the tire 11 from slipping, allowing the mopping robot 10 to smoothly enter the base station 20.

[0039] In another embodiment of the present invention, see Figure 4 and Figure 6 As shown, the distance L3 between two adjacent first ribs 111 of the mopping robot is greater than or equal to the width L4 of the second rib 211.

[0040] During actual walking, the first rib 111 and the second rib 211 form a mutually interlocking structure, that is, the first rib 111 falls between the two adjacent second ribs 211, and the second rib 211 is also inserted between the two adjacent first ribs 111. In this way, the probability of the tire 11 slipping is small, which greatly improves the reliability of the mopping machine 10 entering the base station 20.

[0041] In another embodiment of the present invention, see Figure 3 and Figure 6As shown, the height H1 of the first rib 111 of the mopping robot is greater than or equal to the height H2 of the second rib 211 .

[0042] During walking, after the first rib 111 falls between two adjacent second ribs 211, under the action of the mopping machine 10's own gravity, the first rib 111 presses against the walking surface 21, thereby increasing the contact area between the tire 11 and the walking surface 21, and then increasing the friction of walking, so that the mopping machine 10 can enter the base station 20 more reliably and more smoothly.

[0043] In another embodiment of the present invention, the first rib 111 of the mopping robot includes a first rib 1111 and a second rib 1112, which are arranged in a discontinuous manner along the circumference of the tire 11. During travel, the first rib 1111 and the second rib 1112 easily deform, increasing the contact area between the tire 11 and the walking surface 21, thereby increasing friction, reducing the probability of tire 11 slipping and improving the reliability of the mopping robot 10 entering the base station 20.

[0044] In another embodiment of the present invention, see Figure 4 As shown, the first rib 1111 of the mopping robot provided includes a first inclined segment 11111 and a first straight segment 11112 connected to each other; the second rib 1112 includes a second inclined segment 11121 and a second straight segment 11122 connected to each other; the first straight segment 11112 and the second straight segment 11122 are both arranged parallel to the axis of the tire 11 and are arranged at intervals along the circumference of the tire 11, and the tire 11 has a symmetry plane perpendicular to the axial direction of the tire 11, and the first inclined segment 11111 and the second inclined segment 11121 are respectively arranged on both sides of the symmetry plane, and extend towards each other in an inclined direction away from the symmetry plane. Specifically, the first rib 1111 and the second rib 1112 are symmetrically arranged in opposite directions about the symmetry plane, so that the two tires 11 on the mopping machine 10 can be used interchangeably, and there is no need to distinguish between the left and right tires 11, which facilitates installation; wherein, the spacing between adjacent first ribs 1111 is the distance between the two adjacent first straight segments 11112 and the second straight segment 11122. In addition, the two adjacent first inclined segments 11111 and the second inclined segments 11121 gradually expand from the middle to both sides, which will not prevent the second rib 211 from embedding into the adjacent first rib 1111.

[0045] Furthermore, the first inclined segment 11111 is connected to the first straight segment 11112, the first straight segment 11112 and the second straight segment 11122 are disconnected, and the second straight segment 11122 is connected to the second inclined segment 11121, so that the first rib 111 presents a continuous-intermittent-continuous state from left to right. When walking, the mopping machine 10 compresses the gap between the first straight segment 11112 and the second straight segment 11122, causing it to deform and increase the ground contact area, thereby increasing the friction of walking and improving the stability of walking.

[0046] In another embodiment of the present invention, see Figure 4 and Figure 6 As shown, the spacing L5 between the first straight segment 11112 and the second straight segment 11122 of the provided mopping robot is greater than or equal to the width L4 of the second rib 211. This allows the second rib 211 to be inserted between the first straight segment 11112 and the second straight segment 11122. As the tire 11 rotates, the second rib 211 directly contacts the first straight segment 11112 or the second straight segment 11122, generating thrust that propels the mopping robot 10 forward, thereby increasing the reliability of the mopping robot 10 entering the base station 20.

[0047] In another embodiment of the present invention, see Figure 4 and Figure 6 As shown, when the second rib 211 of the provided mopping robot is inserted into the first straight segment 11112 and the second straight segment 11122, the second rib 211 is located between the first inclined segment 11111 and the second inclined segment 11121. This allows the second rib 211 to be fully inserted between the first rib 1111 and the second rib 1112. As a result, when the tire 11 rotates, the second rib 211 directly contacts the first and second ribs 1111 and 1112, generating thrust that propels the mopping robot 10 forward and improving the reliability of the mopping robot 10 entering the base station 20. Specifically, the second rib 211 is short and can be fully inserted into the gap formed by the first straight segment 11112, the second straight segment 11122, the first inclined segment 11111, and the second inclined segment 11121.

[0048] In another embodiment of the present invention, see Figure 3 As shown, the tire 11 of the provided mopping robot is provided with a plurality of through-holes 112 spaced apart along the circumference of the tire 11, with the axes of the through-holes 112 parallel to the axis of the tire 11. As the tire 11 rotates and moves, under the force of the mopping robot 10 itself, the tire 11 deforms at the through-holes 112, thereby increasing the deformation of the tire 11, increasing the contact area between the mopping robot 10 and the ground or walking surface 21, and increasing friction, thereby improving the anti-slip performance of the mopping robot 10 and enabling the mopping robot 10 to smoothly enter the base station 20.

[0049] In another embodiment of the present invention, the through hole 112 of the mopping robot is located between the first straight segment 11112 and the second straight segment 11122; specifically, during the rotation and walking process of the tire 11, the structural strength between the first straight segment 11112 and the second straight segment 11122 is weak, and under the action of the gravity of the mopping machine 10 itself, the first straight segment 11112 and the second straight segment 11122 are more likely to deform, so that the contact area between the ground and the first rib 1111 is larger, the friction is greater, and the walking reliability of the mopping machine 10 is better; in addition, when the first straight segment 11112 is in front and the second straight segment 11122 is in the back, when the first straight segment 11112 is deformed in contact with the ground, it will affect the second straight segment 11122, causing the second straight segment 11122 to deform before contacting the ground, thereby increasing the friction between the mopping machine 10 and the ground, improving the anti-slip ability of the mopping machine 10, and the walking reliability.

[0050] In another embodiment of the present invention, the mopping robot is provided such that, in the radial direction of the tire 11, the through hole 112 is located on the inner side of the first rib 111; and in the circumferential direction of the tire 11, the through hole 112 is located between two adjacent first ribs 111. During the rotational movement of the tire 11, the structural strength between the two adjacent first ribs 111 is weak, and the two adjacent first ribs 111 are more easily deformed under the weight of the mopping robot 10. This increases the contact area between the ground and the first ribs 111, increases the friction, and improves the reliability of the mopping robot 10. Furthermore, when the front first rib 111 deforms upon contact with the ground, it affects the rear first rib 111, causing it to deform before contacting the ground. This increases the friction between the mopping robot 10 and the ground, improving the anti-slip capability and the reliability of the mopping robot 10.

[0051] Specifically, a through hole 112 is provided between the first straight segment 11112 and the second straight segment 11122, or a through hole 112 is provided between two adjacent first ribs 111, or a through hole 112 is provided between the first straight segment 11112 and the second straight segment 11122 and between two adjacent first ribs 111; the specific setting can be set according to production and is not limited here.

[0052] In another embodiment of the present invention, see Figure 1 、 Figure 5 and Figure 6As shown, the mopping robot base station 20 has an entrance for the mopping machine 10. A running surface 21 extends downwardly and obliquely from the lower edge of the entrance toward the outside of the base station 20 until it contacts the ground. Specifically, the mopping machine 10 enters the base station 20 along the inclined running surface 21, making it easier for the mopping machine 10 to cross a certain height and enter the base station 20, making entry into the base station 20 much simpler.

[0053] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
