Airbag type self-adaptive treadmill

Abstract

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.

Description

technical field [0001] The invention relates to fitness equipment, in particular to an airbag type self-adaptive treadmill. Background technique [0002] Studies have shown that running on cement and asphalt roads requires the body to bear a weight equivalent to three times its body weight, which is a great load on the knees. And using a treadmill can effectively reduce a certain amount of stress. Traditional treadmills mainly use shock-absorbing pads or springs for shock absorption. Shock absorbing pads are mostly made of rubber, and the rubber itself cannot be made too soft, so it is too weak to absorb the pressure on the knee. Because spring shock absorption is rigid, all rigid materials have a disadvantage, that is, abnormal noise is produced, which can achieve shock absorption, but also produces noise. Therefore, developing a treadmill treadmill that can adaptively adjust the hardness of the running board and has no noise has become an urgent problem to be solved by ...
