Specifically, the main housing 21 includes a lower cover 214 and an upper cover 212 that are fastened to each other, and the fastened upper cover 212 and lower cover 214 together form a main accommodating cavity 216 for accommodating components of the cleaning device 100. It is understood that the specific shapes of the lower cover 214 and the upper cover 212 are not limited, in some embodiments, the cross-sections of the lower cover 214 and the upper cover 212 are substantially circular, and in other embodiments, the cross-sections of the lower cover 214 and the upper cover 212 may also be square.
Further, the lower cover 214 is provided with a first mounting groove 2141 and a second mounting groove spaced apart from each other along the first direction, the first mounting groove 2141 is communicated with the main accommodating cavity 216 and the external environment for installing the front driving wheel assembly 23, and the second mounting groove is communicated with the main accommodating cavity and the external environment for installing the rear traveling wheel assembly. Moreover, the first mounting groove 2141 and the second mounting groove are respectively located on two sides of the center point of the lower cover 214, so the orthographic projections of the front driving wheel set 23 and the rear driving wheel set on the main housing 21 are respectively located on two sides of the center point of the main housing 21.
In this way, the front driving wheel set 23 and the rear road wheel set are respectively mounted on the front half part and the rear half part of the main housing 21, thereby forming a front driving mode. During the traveling of the cleaning device 100, the front half portion provided with the front driving wheel group 23 is always positioned in front of the rear half portion provided with the rear traveling wheel group. It can be understood that the specific opening positions of the first mounting groove 2141 and the second mounting groove can be set according to the shape and structure of the main housing 21, so as to meet the requirements of flexibility and obstacle crossing performance of the cleaning device 100.
The front drive wheel set 23 includes two actively rotating front drive wheels 232. Specifically, the lower cover 214 is provided with two first mounting grooves 2141 spaced apart from each other along a second direction perpendicular to the first direction, the two front driving wheels 232 are mounted to the main accommodating cavity 216 at intervals along the second direction, and extend out of the main accommodating cavity 216 through the first mounting grooves 2141 to contact with the placement plane.
Each front driving wheel 232 comprises a driving unit 2323 and a front driving wheel main body 2321 installed on the driving unit 2323, the driving unit 2323 is accommodated in the main accommodating cavity 216, a part of the front driving wheel main body 2321 passes through the first installation groove 2141 and extends out of the main housing 21 to contact with the ground, and the driving unit 2323 is used for driving the front driving wheel main body 2321 to rotate so as to realize the traveling function of the cleaning device 100. In this way, the front drive wheel body 2321 actively rotates to actively ride over an obstacle by being driven by the drive unit 2323, and is hard to be caught by the obstacle.
In some embodiments, the distance B between the edge of the outer side of the front drive wheel body 2321 and the inner wall of the side of the upper cover 212 facing the lower cover 214 is a preset safety distance B1. Preferably, the preset safety distance B1 is 0.5mm to 1.0 mm. In this way, the cleaning apparatus 100 has a greater obstacle-surmounting capability by maximizing the use of the space in the main housing 21 and having a larger diameter D while ensuring smooth rotation of the front drive wheel 232. The diameter D of the front driving wheel 232 is a-B-C, a represents the maximum distance of the upper cover 212 from the lying plane, and C represents the thickness of the upper cover 212.
The rear road wheel set comprises a rear road wheel 25 which is provided with no power unit and is driven to rotate. Specifically, in the second direction, one second mounting groove is located between two first mounting grooves 2141, and the rear road wheels 25 are partially received in the main housing 21 and partially extend out of the main housing 21 from the second mounting groove to contact the ground. Specifically, in some embodiments, the rear road wheels 25 are universal wheels with variable rotation directions, and the rear road wheels 25 are appropriately set to have a larger diameter to prevent the rear road wheels 25 from being too small to affect the overall obstacle crossing capability of the cleaning device 100.
Thus, in the direction of the interval between the two front driving wheels 232, the rear traveling wheels 25 are located between the two front driving wheels 232, and the rear traveling wheels 25 can rotate around different directions under the driving of the front driving wheels 232 so as to enable the cleaning device 100 to smoothly travel.
In the cleaning device 100, the walking power is from the front driving wheel 232 which rotates actively, and the front driving wheel 232 makes full use of the space of the main accommodating cavity 216 and has a larger diameter, so that the cleaning device 100 has higher power and stronger obstacle crossing capability, thereby having higher adaptability to different terrains and environments and better cleaning effect.
