Abstract

The invention provides an artificial limb device with a terrain recognition function. The artificial limb device comprises a knee joint motor assembly, an ankle joint motor assembly, a connecting rod assembly, a controller, a depth camera 18 and a sensor assembly. The knee joint motor assembly is connected with one end of the connecting rod assembly, the other end of the connecting rod assembly is connected with the ankle joint motor assembly, the knee joint motor assembly is provided with the artificial limb socket connector 1, the artificial limb socket connector 1 is connected with an external device, the sensor assembly is connected with the ankle joint motor assembly, and the depth camera 18 is connected with the controller. The controller is connected with the knee joint motor assembly and the ankle joint motor assembly; the depth camera 18 can output topographic conditions to the controller, and the controller can control the knee joint motor assembly and the ankle joint motor assembly to rotate. According to the invention, the depth camera is adopted to obtain topographic data, and the controller synthesizes the current topographic type to obtain the technical means of the optimal control strategy, so as to meet the use requirements of various different topographies.

Description

technical field [0001] The invention relates to the field of lower limb powered prosthetics, in particular to a prosthetic device with terrain recognition function, especially a height-adjustable knee-ankle dual-motor powered prosthetic device with terrain recognition function. Background technique [0002] According to the results of the second national sample survey of disabled persons released by the State Council in December 2006, the proportion of disabled persons in my country's total population is 6.34%, and the number of lower limb amputations is about 1.58 million. In the past five years, due to factors such as diseases, traffic accidents, industrial injuries, and natural disasters, the number of thigh amputations has increased year by year, which has greatly increased the burden on society. With the continuous improvement of the people's economy and living standards, the ability of the disabled to pay is also increasing. The demand for prosthetics is no longer limi...
