During high-speed rotation, the grass-cutting rope can generate corresponding cutting force. The grass-cutting rope is set in the winding component, which is set in the base. The base is installed on the second mounting plate. The base is driven by a motor to rotate, which can drive the grass-cutting rope to rotate around the central axis. The grass-cutting rope can generate the power to cut grass. The first mounting plate and the second mounting plate are stacked and installed. The components installed on each mounting plate are different. The motor is installed on the side of the first mounting plate away from the ground, and the grass-cutting rope is installed on the side of the second mounting plate closer to the ground. The protective component is circumferentially set on part of the edge of the second mounting plate, such as half of the edge of the second mounting plate, and the protective component can be set close to the side of the machine body.

[0058] In this embodiment, a mounting plate is provided in the grass-cutting module 8 with grass-cutting function to prevent the motor from colliding with other objects, thereby ensuring normal operation. At the same time, a protective component is provided and can be placed around the edges of the second mounting plate and the first mounting plate to prevent small objects generated by grass cutting from heading towards the user, thereby avoiding safety hazards.

[0059] like Figure 7 As shown in the figure, a garden robot 11 disclosed in this application includes a mowing module 8 and a front end 13. The front end 13 is provided with a collision strip 14. The mowing module 8 is connected to the front end 13.

[0060] Among them, the front 13 of the garden robot 11 can be connected to the body through a detachable structure. The front 13 can be fixedly connected to the rear of the body through the mounting structure 9. The mounting structure 9 and the collision strip 14 are provided on the front 13 (the collision strip 14 can be set at the position of the front 13 in the forward direction, while the mounting structure 9 is set at one side of the front 13). The grass cutting module 8 is protruding relative to the body and the front 13, which is beneficial for the grass cutting module 8 to cut the grass in the boundary area.

[0061] In this embodiment, a collision strip 14 and a mounting structure 9 can be installed together at the front of the vehicle head 13. After the garden robot 11 has a slight collision with the obstacle via the collision strip 14, the controller controls the garden robot 11 to stop moving. When the garden robot 11 has a large collision with the obstacle, the mounting structure 9 detaches, and the controller controls the garden robot 11 to stop moving. Both structures can prevent the garden robot 11 from continuing to collide with the obstacle, thereby protecting the equipment.
