Abstract:
1. A foldable treadmill, comprising: a bracket, a platform, a lifting device, a folding frame, a motor, a linear actuator, and a control board, wherein: the bracket comprises two supporting sticks, two tracks with each track being arranged at a side of a respective one of the two supporting sticks adjacent to the platform, and a rear linkage with two ends respectively connected with the two supporting sticks; the platform is arranged above the bracket and comprises a base frame, a running board arranged on the base frame; and a belt moving around the running board; the lifting device comprises a rod connected with the bracket, and two pull members respectively arranged at two ends of the rod; the folding frame is arranged between the bracket and the platform, and comprises two bars and a link bar, in which the link bar has two ends respectively connected with the two bars, and a middle portion of each bar respectively connects with the two pull members of the lifting device, and wherein a front end of each of the two bars is used as a pivotal point to rotate the folding frame, and a rear end of each of the two bars has a wheel respectively placed in the two tracks; the motor is arranged near to a front end of the platform for providing driving force; the linear actuator is horizontally laid on the rear linkage, a first end of the linear actuator has a lifting tube connected with the link bar of the folding frame, whereby the linear actuator is configured to drive the lifting tube to move toward the link bar, so as to push the link bar of the folding frame, and thus cause the wheel to move forward, so as to raise the lifting device, and thus raise the front end of the platform, and whereby when the lifting tube is driven toward the linear actuator, the wheel will be pulled backward, and thus lower the front end of the platform; and the control board is arranged at a side of the front end of the treadmill and arranged at an opposite side of the motor.
