The outer cover 6 is provided with a first position-limiting portion 6B, in this embodiment, the position-limiting portion 612 is a protrusion (shown by a dotted line in fig. 12) disposed on the inner side of the outer cover 6, the housing 1 is provided with a second position-limiting portion 15 matched with the first position-limiting portion 6B, in this embodiment, the second position-limiting portion 15 is a protrusion disposed at the end of the wheel cover portion 13. The outer cover 6 can also be provided with a position switch 7, and the shell 1 is provided with a contact rod 16 matched with the position switch 7. When the cleaning robot 100 is lifted, the position switch 7 is triggered by the touch bar 16, and the first position-limiting portion 6B also abuts against the second position-limiting portion 15, so as to prevent the housing 1 from continuing to rotate toward the outside of the housing 6.
In the embodiment of the present invention, the housing 6 includes a housing upper shell 61 and a housing lower shell 62, and the rotating shaft portion 14 is installed on one side of the housing lower shell 62. The housing upper shell 61 and the housing lower shell 62 may be fixedly connected by a threaded fastener or by a snap. The housing upper case 61 is provided with a recess 613 on the outer side, the micro switch 7 is mounted on the recess 613, and a window 614 for the touch rod 16 to touch the micro switch 7 is opened on one side of the recess 613.
Since the housing 1 is pivoted to the housing 6, the housing 1 can rotate inwardly or outwardly around the housing 6, so that the wheels 4 can rotate around the housing 6 (within the range defined by the first limit portion 6B), and the spring 5 provides elastic force all the time during the rotation of the housing 1. When the driving wheel module 110 is disposed at the bottom of the cleaning robot 100, the position switch 7 and the motor 2 are electrically connected to a control system of the cleaning robot 100. Under the action of the self gravity of the cleaning robot 100, the wheels 4 are moved into the housing 6 by the reaction force of the ground, the feeler lever 16 is separated from the position switch 7, and the wheel cover part 13 separates the wheels 4 from the housing 6, so that the wheels 4 do not rub against the housing 6 when rotating. In such a case, the cleaning robot 100 normally operates; when the cleaning robot 100 encounters an emergency, for example, when the cleaning robot 100 is lifted up by a person, the wheels 4 are ejected outwards under the elastic force of the springs 5, the trolley 16 touches the position switch 7, and the control system of the cleaning robot 100 can obtain a signal from the position switch 7, so as to control the driving wheel module 110 to stop working, thereby facilitating the user to operate or carry the cleaning robot 100.
Figure 16 is a simple schematic view of the projection P1 on the ground when the brush 22 is rotated and the projection P2 of the wheel 4 on the ground. As can be seen in fig. 1, the brush 22 is arranged adjacent to the wheel 4 such that the projection P1 of the brush 22 on the ground when rotated has an overlap P12 with the projection P2 of the wheel 4 on the ground (see fig. 16).
As shown in fig. 17, when the cleaning robot 100 is placed on the ground, the wheels 4 retract into the housing 6 under the gravity of the cleaning robot 100, and the brush 22 rotates without touching the wheels 4, thereby ensuring that the brush 22 does not touch the wheels 4 when the cleaning robot 100 travels on the ground.
As shown in fig. 18, when the cleaning robot 100 is lifted, the wheels 4 protrude further to the outside of the housing 6 by the elastic force of the spring 5, in this case, if the brush 22 rotates, the brush 22 may contact the wheels 4, and therefore, the rotation of the brush 22 needs to be controlled to be stopped to prevent the brush 22 from contacting the wheels 4.
