One kind of plantar force measurement device

The present invention discloses a plantar force measuring device comprising a load mechanism and the transmission mechanism. Transmission through speed motor drives the driving force shaft, main power shaft on which is fixed by the first and second torsion spring torsion torque transmitted to the front left and right pedal drum pedal before drum, controlling motor speed to controlling the velocity of the left pedal and the right pedal. Left and right pedal pedal symmetrical parallel installation, rear left and right rear roller pedal drum pedal is located on the same axis. Dynamometer through the left pedal and roller bearings under and in front of the pressure sensor mounted on the rear portion of the left and right foot pressure and shear measurements on the right pedal. It is measured by the movement of displacement and walking on the measuring device, and then study plantar force under different circumstances gait. Simple measuring device structure, main power input shaft torque to achieve front left and right pedals rotation of the drum, to avoid the interference of external input force, improve the measurement accuracy of the plantar force.
