Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The present application provides an embodiment, a cleaning robot, as shown in fig. 1-4, comprising a housing assembly 1, a cleaning member 2, and a driving assembly 3;

the driving assembly 3 comprises a direct drive motor 31, a transmission piece 32 and an output piece 33 which are sequentially connected, the output piece 33 is connected with the cleaning component 2, and the direct drive motor 31 controls the transmission piece 32 and the output piece 33 to drive the cleaning component 2 to rotate. The cleaning robot in this embodiment transmits power from the transmission member 32 to the output member 33 by the operation of the single direct drive motor 31, and the output member 33 outputs the power to the cleaning member 2, so that the cleaning member 2 is rotated to complete the cleaning work. The direct drive motor 31 of this application replaces traditional gear motor, makes cleaning machines people's drive structure succinct high-efficient, and the noise is few. That is, the cleaning robot of the embodiment uses the direct drive motor 31 by reducing the number of the motors, optimizes the structures of the cleaning part 2 and the driving assembly 3, improves the utilization rate of the inner space of the robot, and reduces the cost.

In this embodiment, the housing assembly 1 of the cleaning robot includes a lower housing 12 and an upper housing 11, the direct drive motor 31 is installed in a cavity formed by the upper housing 11 and the lower housing 12, the direct drive motor 31 is fixedly connected to an inner wall of the housing assembly 1, an output hole 121 is formed in the bottom of the lower housing 12, the direct drive motor 31 penetrates through the output hole 121 to be fixedly connected with the transmission member 32, and then the transmission member 32 is connected with an output member 33 outside the lower housing 12 and the cleaning component 2.

In this embodiment, at least two driving wheels 13 for driving the cleaning robot to move are disposed at the bottom of the lower housing 12. The robot is able to realize walking and steering of the robot based on the adjustment of the speed between the drive wheels 13, i.e., the differential speed. And, the bottom of said lower shell 12 is still equipped with at least one driven wheel 14, this embodiment uses the universal driven wheel 14, correspond to the mounting position of the driving wheel 13, and then support the machine and keep it in the horizontal state.
