Embodiment approach

[0053] refer to Figure 8 Shown is another embodiment of the automatic lawn mower 20a of the present invention, the automatic lawn mower 20a has a similar structure to the automatic lawn mower 20 in the first embodiment, the difference is that the automatic lawn mower 20a has four wheels. For the convenience of expressing the same structure, the same number is used to indicate and will not be repeated. The robot mower 20a includes a plurality of sensors 7' disposed on the front housing 1a, a pair of front wheels 5a, 5b are supported under the front housing 1a of the robot mower 20a, and a pair of rear wheels 3a, 3b is provided below the rear case 1c. Wherein a pair of front wheels 5a, 5b adopt universal wheels, and a pair of rear wheels 3a, 3b are driven steering wheels, which are driven by a drive motor 4 to rotate. When the obstacle detection device detects an obstacle, the control device controls one of the electromagnetic clutches to energize and disconnect the coupling...

Abstract

The invention relates to self-driven equipment, in particular to an automatic mower with drive and control systems. The automatic mower comprises a shell, wheels supporting the shell, a driving device arranged on the shell and used for controlling the automatic mower to move, a cutting device, obstacle detection devices and a control device, wherein the control device is connected with the driving device and the obstacle detection devices and is used for controlling the driving device to move the automatic mower when the obstacle detection devices receive the information indicating existence of obstacles; and the driving device comprises a driving motor which drives one or two of a pair of parallel wheels in an operable manner. The automatic mower has the advantages of low cost and light weight and is efficient and energy-saving.

Description

technical field [0001] The invention relates to a self-driving device, in particular to an automatic lawn mower with a driving and control system. Background technique [0002] Common automatic lawn mowers on the market usually have a pair of driving rear wheels and a pair of supporting front wheels. Corresponding to the drive speed of the rear wheels. When the automatic lawn mower moves straight ahead on the ground, the speeds of the two driving rear wheels are the same. When the automatic lawn mower encounters an obstacle in the process of moving forward, the detection device transmits the detected obstacle signal to the control mechanism , the control mechanism judges and executes the steering of the automatic lawn mower. During the turning process of the automatic lawn mower, the driving speeds of the two driving rear wheels are different. When the automatic lawn mower turns to the left, the driving speed of the left rear wheel is smaller than the driving speed of the ...
