After the first magnetic element 6 and the second magnetic element 7 are connected with the metal sheet 9, the first magnetic element 6 and the second magnetic element 7 mounted in the first hole 51 can realize the limit of the metal sheet 9 in the height direction due to the magnetic attraction effect of the first magnetic element 6 and the second magnetic element 7, and meanwhile, the metal sheet 9 can also realize the limit of the metal sheet 9 in the front-rear direction of the first magnetic element 6 and the second magnetic element 7. The structure of the scram button 5 can be more stable through the cooperation between the first magnetic piece 6 and the second magnetic piece 7 and the metal sheet 9, and the structure of the scram button 5 is further simplified without additionally considering the fixation of the metal sheet 9.

Further, the diameter of the second hole 91 is smaller than that of the first hole 51, so when the first magnetic element 6 and the second magnetic element 7 are inserted into the corresponding first hole 51 and connected to the corresponding second hole 91, the contact area between the second hole 91 and the first magnetic element 6 and the second magnetic element 7 is smaller, and the magnetic attraction force is also relatively smaller, so that the first magnetic element 6 and the second magnetic element 7 are easier to be taken down from the emergency stop button 5 by a user, and the user experience is improved.

It should be noted that, because the sizes and types of the magnets selected by the first magnetic member 6 and the second magnetic member 7 are many, and the magnetic field strengths are different, in other embodiments, the detection plane of the hall sensor 8 may be located above the horizontal plane where the center line of the first magnetic member 6 is located in the height direction of the intelligent mower 100, and it may be guaranteed that pressing or pulling the emergency stop button 5 can trigger the intelligent mower 100 to perform emergency braking, so that the detection plane of the hall sensor 8 is located above the horizontal plane where the center line of the second magnetic member 7 is located.

The present utility model is not limited to the above-described embodiments. Those of ordinary skill in the art will readily appreciate that many other alternatives to the intelligent mower of the present utility model are possible without departing from the principles and scope of the present utility model. The protection scope of the present utility model is subject to the claims.
