The invention relates to a mounting structure and a control method of a hand brake travel switch, the mounting structure comprises a trapezoidal threaded screw rod, a brake cable pull rod head, a lever, a cam and a travel switch, one end of the trapezoidal threaded screw rod is provided with a bevel gear, the bevel gear is provided with a sliding block, one side of the sliding block is provided with a first limiting bolt, one end of the lever sleeves the first limiting bolt, and the other end of the lever sleeves the second limiting bolt. The cam mechanism is used for connecting the hand braking mechanism and the travel switch and controlling the travel switch to be turned on and turned off, meanwhile, it is guaranteed that the compression amount of a rotating arm of the travel switch is not too large, the service life of the travel switch is guaranteed, the space of a vehicle body is fully utilized for structural layout, and the interference problem is solved. On the premise that the service life of the travel switch is guaranteed, a cam structure is used for connecting the hand braking mechanism and the travel switch, so that the mechanical action of hand braking is converted into an air pressure signal, and the air pressure signal is input into a braking indicator.
