The walking wheel described in the utility model comprises a large wheel and a small wheel, and the small wheel is nested in the large wheel.

The bottom of the front side of the chassis of the utility model is an inclined surface with a slope.

A pressure sensor is installed between the bearing described in the utility model and the bearing gland.

Universal wheels are arranged below the front side of the chassis of the utility model.

The chassis of the utility model is provided with a handle, a battery compartment for placing batteries and a charging metal point.

Compared with the prior art, the utility model has the following beneficial effects: 1. It is provided with a collision signal processing device that can automatically avoid obstacles. Press the micro switch, after the circuit control board receives the signal, it will give the walking motor an instruction to avoid obstacles. After the external force of the collision disappears, the push plate will return to its original position under the action of the elastic component; 2. The axle of the walking wheel is located in the bearing , the bearing is fixed on the chassis with a bearing gland, which can reduce the impact force generated by the ground bumps on the running wheel during operation, and achieve an anti-seismic effect. A pressure sensor can also be installed between the bearing and the bearing gland for detection The pressure of the walking wheels on the machine is used to detect whether the machine is suspended in the air; 3. The bottom of the front side of the chassis is an inclined surface with a slope, which can effectively reduce the resistance caused by uneven ground or excessive grass growth during the travel process; 4. The travel motor and travel wheels are installed on the rear side of the chassis, and the front side of the chassis is equipped with universal wheels, which are driven by the rear wheels, which can reduce the resistance encountered by the mower during the turning process; 5. The travel wheels are nested by each other. Composed of a large wheel and a small wheel, the large wheel can be disassembled from the small wheel. If the large wheel is removed for mowing, the height of the mowing will change, which can realize the adjustment of the mowing height.

Detailed ways

Referring to FIGS. 1 to 3 , this embodiment includes a chassis 10 , a traveling motor and a mowing motor, and there is no sloped surface below the front side of the chassis 10 . Two road wheels 11 are symmetrically installed on the bottom of the rear side of the chassis 10, and a universal wheel 14 is installed on the front side of the chassis 10. The wheel shaft 12 of the road wheels 11 is located in two bearings (not shown in the figure), and the bearings pass through the bearing gland 3 fixed on the chassis 10. Traveling motor (not shown in the figure) is fixed on chassis 10 rear side below by traveling motor gland 4, and transmission gear 1 is installed on the output shaft of traveling motor, and transmission gear 2 is installed on the axle 12 of walking wheel 11, two transmission gears Realize the power output by belt transmission between them, and the traveling motor drives the traveling wheel 11 to rotate. A collision signal processing device is also installed on the chassis 10, and the device includes a push plate 8 positioned at the front side of the chassis 10, four micro switches 7 and a circuit control board 19, the micro switches 7 are connected with the circuit control board 19, and the push plate 8 can move along the chassis 10. The chassis 10 is provided with a chassis tension spring fixed column 17, and the push plate 8 is provided with a push plate tension spring fixed column 16. An elastic part is connected between the two tension spring fixed columns. Spring 9, micro switch 7 can be pressed down after push plate 8 moves certain distance. Mowing motor (not shown in the figure) is installed on the mowing motor mounting hole 15 places on the chassis 10, and is fixed on the chassis 10 by flange 5, and flange 5 can be 1 according to the number of mowing motors. ~3. The rear side of the chassis 10 is provided with a handle 6 to facilitate the handling of the machine, the chassis 10 is provided with a battery compartment 18 for placing batteries, and the front side of the chassis 10 is provided with a charging metal point 13 for charging.

Referring to Fig. 4, the traveling wheel 11 includes a large wheel 20 and a small wheel 21, the small wheel 21 is nested in the large wheel 20, and the large wheel 20 can be disassembled from the small wheel 21 to adjust the mowing height.

In addition, the elastic component can also be a component that can achieve the same effect, such as an elastic steel sheet. A pressure sensor can also be installed between the bearing and the bearing gland 3, which is used to detect the pressure of the road wheels to the machine, to detect whether the machine is suspended, and further improve performance.

When the lawn mower is walking, if an obstacle is encountered, the obstacle will give the push plate 8 an external force, and the push plate 8 will move in the direction of the force. When the stroke reaches a certain distance, the micro switch 7 will be pressed and opened, and the circuit control board 19 will be activated. signal, the circuit control board 19 gives the walking motor an instruction to avoid obstacles, thereby realizing avoiding obstacles. Because there is extension spring 9 to pull between chassis extension spring fixed post 17 and push plate extension spring fixed post 16, when the collision external force disappears, that is, there is no obstacle in the walking direction, push pedal 8 recovers the position before the collision.
