Detailed Description

The technical aspects of the embodiments of the present invention will be described in detail and fully with reference to the accompanying drawings, in which the embodiments of the present invention are shown and described, and it is to be understood that the embodiments described are only some embodiments of the present invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and to simplify the description, but do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", may explicitly or implicitly include one or more of the described features. In the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Referring to fig. 1, 2, 3, 4 and 5, in order to provide a first embodiment of the present invention, a mobile robot, such as a floor sweeper, a floor cleaner or a floor washer, is generally assembled from a base 10 and a cover plate 20, wherein the base 10 is installed with a driving unit (not shown), a functional unit (not shown), a sensing unit and a circuit board 60, and the driving unit, the functional unit and the sensing unit can be controlled by the circuit board 60, so as to autonomously complete a corresponding work task.

Referring to fig. 3, in order to avoid damage to the laser radar 30 caused by external obstacles and living objects, a cover 50 is further installed at the opening 21, an accommodating cavity 51 is formed in the cover 50, and a plurality of transmitting ports 52 are formed on the peripheral wall of the cover 50. The laser radar 30 is installed in the accommodating cavity 51, a laser transmitter and a laser receiver are arranged on the laser radar, light emitted by the laser transmitter is reflected back by obstacles in the working environment after being emitted through the emitting port 52 and is received by the laser receiver through the emitting port 52, and therefore the distance between the obstacles is obtained. After the laser radar 30 is mounted on the housing 50, a certain gap 22 is generally formed between the laser radar 30 and the housing in order to ensure that the laser radar 30 can perform an effective rotation movement, and at this time, the transmitting opening 52 and the gap 22 form a passage for water or dust from the outside, so that the circuit board 60 is easily exposed to external contaminants (such as water or dust). In this embodiment, a sealing member 40 is further disposed at the opening 21, and the sealing member 40 is fixed to the cover 50 or the cover plate 20 through a connecting member 44 to artificially block the passage, so that the sealing member 40 blocks the external contaminants.

Further, the sealing member 40 is a plastic sheet commonly used at present, which has low manufacturing cost and molding requirement, and also has excellent sealing performance. The outer edge 41 of the sealing member 40 is formed with a plurality of through holes 42 spaced apart from each other, and a connecting member 44 is inserted through the through holes 42 to fix the sealing member 40 to the cover plate 20. In the present invention, the connecting member 44 is a screw. Preferably, the middle portion 45 of the sealing member 40 is recessed downward relative to the edge 41, so that an inclined surface 46 is formed between the edge 41 and the middle portion 45, and the inclined surface 46 and the middle portion 45 form a recessed area 43, on one hand, the recessed area 43 can avoid the laser radar 30, so that the laser radar 30 has a larger installation space, and on the other hand, external pollutants can be gathered in the recessed area 43 through the inclined surface 46, so that the external pollutants are prevented from entering the inside of the main body through a connection gap between the sealing member 43 and the cover plate 20, and the sealing effect can be effectively improved.

Referring to fig. 3, 6 and 7, in accordance with the second embodiment of the present invention, the sealing member 40 may not completely prevent dust or water from entering the main body, and the sealing member 40 may be damaged or damaged due to installation problems, so that external contaminants may still enter the main body through the opening, thereby damaging the circuit board 60. In order to avoid the similar situation, a protective cover 70 is covered on the circuit board 60, and the protective cover 70 can provide secondary protection for the circuit board 60, so that the protection effect for the circuit board 60 is greatly improved. The shape of the protective cover 70 matches with the shape of the circuit board 60 and the electrical components, so that the protective cover 70 can be well matched with the circuit board 60, and the protective cover 70 is fixed on the circuit board 60 or the base 10 through screws. Further, a water guiding groove (not shown) is formed on the protective cover 70, and the water guiding groove forms an inclined surface to improve water guiding efficiency, and the water guiding groove guides water away from the protective cover 70 and flows out through an outlet (not shown) formed on the mobile robot.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
