Description

Technical Field

[0001] The utility model relates to a water surface cleaning robot with an anti-collision function, belonging to the technical field of smart home. Background Art

[0002] In recent years, pool cleaning robots have become a popular industry, and various types of pool cleaning robots have emerged. Among them, the most widely used robots include water surface cleaning robots floating on the pool surface for collecting floating garbage such as fallen leaves. Since the water surface cleaning robot is prone to hitting the pool wall during movement, anti-collision wheels need to be provided.

[0003] As disclosed in the patent with the publication number CN117513278A, the anti-collision structures adopted by most water surface cleaning robots on the market at present have certain limitations. When these devices collide with the pool wall during operation, most of the impact force will be directly transmitted to the central axis and the main body of the machine through the anti-collision wheels. This design may not only cause damage to the anti-collision wheels, the central axis and even the entire machine body, but also the anti-collision effect is not satisfactory, thus shortening the service life of the relevant components and the whole machine. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems existing in the prior art and provide a water surface cleaning robot with an anti-collision function, so as to achieve effective anti-collision of the machine body and extend the service life of the product.

[0005] To solve the above technical problems, a water surface cleaning robot with an anti-collision function of the utility model includes a machine body. A garbage box is provided in the middle of the machine body. Floating boxes are provided on both sides of the machine body. Anti-collision wheels are assembled on the outer edge of the floating boxes, and a plurality of grooves are evenly distributed on the outer ring of the anti-collision wheels.

[0006] Further, the floating box is provided with a notch recessed inward. The anti-collision wheel is arranged in the notch through a central axis bracket, and a rubber ring is sleeved on the central axis of the anti-collision wheel.

[0007] Further, at least 1 / 4 of the anti-collision wheel extends out of the floating box.

[0008] Further, both ends of the central axis bracket are provided with folding ears. A through hole is provided in the middle of the folding ears. The folding ears abut against the limiting plates extending inward of the floating box, and the fastening screws pass through the through holes and are screwed between the limiting plates.

[0009] Further, the ratio of the width of the groove to the diameter of the anti-collision wheel is 1 / 2 - 1 / 4.

[0010] Furthermore, the upper and lower ends of the central shaft of the anti-collision wheel are respectively provided with reduced diameter ring grooves, the rubber ring is sleeved on the reduced diameter ring grooves and clamps the central shaft between the central shaft bracket and the limiting plate.

[0011] Furthermore, the anti-collision wheels are arranged at the corners of the machine body.

[0012] Furthermore, the ratio of the groove width to the anti-collision wheel diameter is 3.3 / 8.

[0013] Compared with the prior art, the present invention has achieved the following beneficial effects: 1. The central shaft and the machine body are elastically connected through a rubber ring, which greatly increases the service life of the anti-collision wheel, the central shaft and the machine body, and greatly increases the service life of the product.

[0014] 2. Adding an anti-collision wheel on the left and right rear sides of the machine body can effectively prevent the machine body from collision and increase the service life of the product; it can effectively help the machine body to get out of trouble when turning, making right-angle turns or in narrow spaces, thereby improving the product's cleaning efficiency and cleaning coverage.

[0015] 3. The contour surface where the anti-collision wheel contacts the obstacle is made into a uniformly distributed small groove shape, which effectively reduces the rolling speed of the anti-collision wheel after hitting the obstacle, thereby effectively reducing the inertia of the machine body's rotation, reducing the impact force of the machine body, and extending the service life of the product.

[0024] In the following description of the present utility model, the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating that the device must have a specific orientation.

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model.

[0027] As Figures 1 to 4 shown, the present utility model provides a water surface cleaning robot with an anti-collision function, including a body 1. A garbage box 2 is provided in the middle of the body 1. Floating boxes 3 are provided on both sides of the body 1. Anti-collision wheels 4 are assembled on the outer edges of the floating boxes 3. A plurality of grooves 41 are evenly distributed on the outer ring of the anti-collision wheels 4. The floating box 3 is provided with a notch 31 that is recessed inward. The anti-collision wheels 4 are arranged in the notch 31 through a central axis bracket 7. A rubber ring 6 is sleeved on the central axis 5 of the anti-collision wheels 4. At least 1 / 4 of the anti-collision wheels 4 extends out of the floating box 3. The anti-collision wheels 4 are arranged at the corners of the body 1. The ratio of the width of the groove 41 to the diameter of the anti-collision wheel 4 is 3.3 / 8.

[0028] As Figure 5 and Figure 6 shown, both ends of the central axis bracket 7 are provided with folded ears 71. A through hole 72 is provided in the middle of the folded ears 71. The folded ears 71 are abutted against the limiting plates 32 extending inward of the floating box 3. The fastening screws 8 pass through the through holes 72 and are screwed between the limiting plates 32.

[0029] Reduced-diameter annular grooves 51 are respectively provided at the upper and lower ends of the central axis 5 of the anti-collision wheels 4. The rubber ring is sleeved at the reduced-diameter annular grooves and clamps the central axis 5 between the central axis bracket 7 and the limiting plate 32.

[0030] Through continuous exploration and proofing tests, the utility model breaks the common technology of the existing anti-collision structure that only rigidly connects the anti-collision component. By setting an anti-collision component structure with two rubber rings, it can effectively buffer the impact force, have a good anti-collision effect, and extend the service life of the anti-collision wheel 4, the center shaft 5, and the body 1; a reduced diameter ring groove 51 is added to each end of the cylindrical surface of the center shaft 5 and a rubber ring is installed to fix the center shaft 5 on the floating box 3 with a center shaft bracket 7; when the body 1 collides with an obstacle, the obstacle usually collides with the anti-collision wheel 4 of the anti-collision component, and the anti-collision wheel 4 transmits the force to the center shaft 5. Since the rubber ring on the center shaft 5 has sufficient elastic deformation, the anti-collision wheel 4 and the center shaft 5 can be easily shifted, resulting in the impact force being effectively buffered, and effectively avoiding impact damage; the structure is simple, practical, and ingeniously conceived.

[0031] The utility model adds an anti-collision component on the left rear side and the right rear side of the body 1; when the body 1 is turning, making a right-angle bend or in a narrow space, the left rear side or the right rear side will encounter an obstacle, and the anti-collision wheel 4 on the left rear side or the right rear side will rotate accordingly to enable the body 1 to avoid the obstacle, thereby effectively preventing the body 1 from being trapped. At the same time, the good and smooth movement performance of the body 1 improves the cleaning efficiency of the product, and the flexible movement performance of the body 1 in a narrow space enables the product to have a higher cleaning coverage rate.

[0032] The utility model features uniformly distributed small grooves 41 on the contoured surface of the anti-collision wheel 4 where it contacts an obstacle. When the anti-collision wheel 4 strikes an obstacle and begins rolling, the uniformly distributed small grooves 41 on the contoured surface cause the wheel 4 to briefly and intermittently stop rolling, significantly reducing its rolling speed. This effectively reduces the inertia of the machine body 1, minimizing the impact force on the machine body 1 and extending the service life of the machine body 1. The ratio of the width of the small grooves 41 on the contoured surface of the anti-collision wheel 4 to the diameter of the central axis 5 is 3.3 / 8, ensuring that the anti-collision wheel 4 continues to roll intermittently after striking an obstacle. Field testing has shown that the product meets intermittent rolling requirements under actual operating conditions.

[0033] The above description is only a preferred embodiment of the present invention, which shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It does not limit the scope of patent protection of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. In addition to the above embodiments, the present invention may have other implementation methods without departing from the spirit and scope of the present invention. The present invention may also have various changes and improvements. Any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the attached claims and their equivalents. The technical features not described in the present invention can be achieved by or using existing technologies, and will not be described here.
