[0033] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, the sweeping robot according to an embodiment of the present invention includes a chassis 100, on which a track groove 110 is provided for the swinging of a mop tray assembly (not shown in the figure). A transmission assembly 200 adapted to the track groove 110 for providing power to the mop tray assembly is connected in the track groove 110. It also includes a dust cover 300, which is disposed at the bottom of the chassis 100. The dust cover 300 has a connecting hole 310 and is rotatably connected to the transmission assembly 200 through the connecting hole 310. When the transmission assembly 200 moves in the track groove 110, the dust cover 300 covers the gap in the track groove 110.

[0034] In practical use, by setting a dust cover 300 that moves with the transmission component 200, the dust cover 300 can cover the gaps in the track groove 110 without affecting the movement of the transmission component 200, thus preventing dust and debris from easily entering the machine through the track groove 110. Traditional robotic vacuum cleaners often use fixed covers or completely open structures. The former restricts the movement range of the mop tray, while the latter cannot effectively prevent dust from entering. This embodiment organically combines the dust cover 300 with the transmission component 200. The dust cover 300 is not just a simple cover, but also an important component of the motion system. When the robotic vacuum cleaner is working in complex floor environments, such as encountering obstacles like carpet edges or thresholds, the dust cover 300 can automatically adjust its position with the movement of the transmission component 200, always maintaining a smooth transition with the lower surface of the chassis 100, avoiding the creation of new jamming points or dust accumulation areas. This design ensures that the machine maintains stable sealing performance during long-term use, significantly reducing the failure rate caused by dust accumulation.

[0035] refer to Figure 3 As shown, it should be noted that in this embodiment, the track groove 110 is an arc-shaped groove with a width of 8mm-20mm. Of course, the contour of the track groove 110 can also be formed by combining multiple curves with different radii of curvature. Meanwhile, the transmission component 200 and the mop disc component are both commonly used technical solutions in the field of robotic vacuum cleaners, and their specific structures and principles will not be elaborated here. For ease of explanation, the transmission component 200 includes a transmission shaft, and the connecting hole 310 is connected to the transmission shaft hole in a shaft-like fit.

[0036] refer to Figure 2 As shown in Figure 3, in some specific embodiments of this utility model, it may also have the following additional technical features: a limiting post 120 is connected to the bottom of the chassis 100, and a limiting hole 320 is provided on the dust cover 300, the limiting hole 320 being axially connected to the limiting post 120. Specifically, the limiting hole 320 is an oblong hole. Preferably, see reference... Figure 3 As shown, the center of the limiting hole 320 (point B in the figure) does not coincide with the center of the track groove 110 (point A in the figure). At this time, the dust cover 300 and the wiping tray assembly can be rotatably or relatively movable together, so that the outward swing and inward retraction of the wiping tray assembly will drive the dust cover 300 to move outward. Within the entire range of outward swing and inward retraction, the dust cover 300 can completely block the movement track hole of the wiping tray assembly. The design of the limiting hole 320 and the limiting post 120 ensures the stability of the dust cover 300 during movement and prevents it from unnecessary deviation or shaking. At the same time, the waist-shaped hole and the arc trajectory of the track groove 110 form a precise fit, so that the dust cover 300 can move smoothly along the predetermined path under the drive of the transmission component 200. The non-coincidence of the center of the limiting hole 320 and the center of the track groove 110 creates a unique movement trajectory, which allows the dust cover 300 to better cover different parts of the track groove 110 during movement. Especially when the mop tray assembly is in the extreme position, it can still maintain an effective sealing effect. At the same time, it can also effectively reduce the size of the dust cover 300, which is more conducive to the overall spatial layout of the robot vacuum cleaner.

[0037] In some specific embodiments of this utility model, it may also have the following additional technical features: the outline of the dust shield 300 includes a first arc 301, a second arc 302, a first rounded arc 303, a straight line 304, and a second rounded arc 305 connected end to end in sequence. Specifically, the connecting hole 310 is located near the connection between the first arc 301 and the second arc 302. This composite curve outline design allows the dust shield 300 to cover the track groove 110 area to the maximum extent, while avoiding interference with other components on the chassis 100. The curvature of the first arc 301 matches the arc shape of the track groove 110, ensuring minimal gap between the dust cover 300 and the edge of the track groove 110 during movement. The second arc 302 coordinates with the outer contour of the chassis 100, making the overall structure more compact. The design of the first rounded corner arc 303 and the third rounded corner arc avoids sharp corners, which not only improves structural strength but also prevents deformation or damage caused by stress concentration during movement. The straight line segment 304 provides necessary structural support for the dust cover 300, ensuring its shape stability during long-term use. The selection of the connection hole 310 position is mainly for fitting the design of the cloth tray assembly, allowing the cloth tray assembly to be closer to the edge of the chassis 100, thus contacting more areas, while maintaining force balance of the dust cover 300 during movement, reducing unnecessary vibration and noise.

[0038] Furthermore, the first arc 301 and the second arc 302 have the same radius, and the centers of the first arc 301 and the second arc 302 are symmetrically arranged about the central axis of the straight line 304. This symmetrical design makes the dust cover 300 more evenly stressed during movement, avoiding vibration problems caused by uneven mass distribution. It also allows the dust cover 300 to maintain a stable posture during movement, preventing unnecessary torsional deformation. The connecting hole 310 is located at the junction of the two arcs, which is precisely the center of mass area of ​​the dust cover 300. This layout allows the transmission component 200 to drive the dust cover 300 with only a small torque, reducing the load on the transmission component 200.

[0039] In some specific embodiments of this utility model, it may also have the following additional technical features: the distance between the center of the limiting hole 320 and the center of the connecting hole 310 is 25mm-35mm.

[0040] In some specific embodiments of this utility model, it may also have the following additional technical features: the bottom of the chassis 100 is raised upward to form a movable plane 130, and a stepped surface 140 is provided between the movable plane 130 and the bottom of the chassis 100. The dust cover 300 is movably disposed on the movable plane 130. Specifically, the limiting post 120 is connected to the movable plane 130. More specifically, the stepped surface 140 is recessed inward to form a groove 141 that matches the contour of the dust cover 300. The clearance formed by the groove 141 allows for better adaptation to the size of the dust cover 300, while reducing interference during movement. The raised height of the movable plane 130 provides sufficient movement space for the dust cover 300 without reducing the internal space of the entire machine and causing a crowded internal layout. The design of the stepped surface 140 not only serves a positioning function but also enhances the structural rigidity of the chassis 100. The fit between the groove 141 and the contour of the dust cover 300 ensures stability during movement, preventing increased resistance due to excessively small gaps or compromised sealing performance due to excessively large gaps. The vertical and horizontal surfaces of the stepped surface 140 are rounded, a design that avoids stress concentration and improves the durability of the chassis 100. The depth of the groove 141 matches the thickness of the dust cover 300, ensuring that the dust cover 300 remains flush with the movable surface 130 after installation. This flush structure ensures the flatness of the lower surface of the chassis 100, preventing jamming when crossing thresholds or carpets. The edge of the groove 141 features a guide slope, which guides the dust cover 300 into precise positioning during assembly.

[0041] In some specific embodiments of this utility model, it may also have the following additional technical features: there are two track grooves 110 respectively connected to the chassis 100, two transmission components 200 are adapted to each other, and two dust cover plates 300 are adapted to each other. Among the various devices on the market, most sweeping robots have dual rotating mops for wiping the floor, so this embodiment is used to adapt to this type of model.

[0042] In some specific embodiments of this utility model, it may also have the following additional technical features: the dust cover 300 is made of a high molecular composite material with excellent wear resistance and self-lubrication, such as polytetrafluoroethylene or polyethylene, etc. These materials have a low coefficient of friction and good dimensional stability, ensuring that the motion accuracy will not be affected by wear during long-term use.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.

[0044] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
