The invention discloses an
airbag type self-adaptive
treadmill. The
treadmill includes a main bracket, a running board and a controller; an
airbag assembly is arranged between the main bracket and therunning board, the
airbag assembly is installed on the main bracket, and the running board is located above the airbag
assembly; the airbag assembly includes a left air bag, a right air bag and an air guide
pipe, wherein the air guide
pipe is communicated with the left air bag and the right air bag; one side of the right air bag is provided with an air pressure conducting
pipe, the air pressure conducting pipe is connected with one end of a tee joint of the air pressure conducting pipe, the other two ends of the tee joint of the air pressure conducting pipe are connected with an
air pump anda
solenoid valve respectively, the
air pump is connected with the controller through an air-pump wire, the
solenoid valve is connected with the controller through a solenoid-valve wire, and the controller is connected with a
position sensor through a
signal transmission line. Compared with the prior art, the
treadmill has the advantages that by detecting a treadmill
signal, through the operationalanalysis of the controller, the
signal is output for inflation and deflation, the effect of automatically adjusting the softness and
hardness of the running board is achieved, and the treadmill has no
noise.
