A power-assisted mechanical leg with a multi-stage energy lock mechanism

Abstract

The invention discloses an assistance type mechanical leg with a multi-stage energy lock mechanism. The mechanical leg comprises a shank fixing plate, a brake cable, a spring, a front foot base plate,elastic pieces, a rear pedal plate, a rear foot base plate, spring teeth, a connecting piece and an ankle fixing plate; one end of the rear foot base plate is connected with the connecting piece, theother end of the connecting piece is connected with the front foot base plate, and a front shoelace is arranged on the side, away from the rear foot base plate, of the upper end of the front foot base plate. Through engaging of the spring teeth and an arc rack, springback in the spring energy storage process can be effectively avoided, through connection of the brake cable, tooth tongues of the spring teeth are pulled by the shank fixing plate to retract into a tooth box at the proper position (starting is about to be carried), and therefore at the proper position (starting is about to be carried), the elastic potential energy of the spring is released; the elastic pieces are inserted into different small holes in the connecting piece, the device can adapt to wearing of different sizes offeet.

Description

technical field [0001] The invention belongs to the field of sports equipment and the technical field of mechanical engineering, and in particular relates to a power-assisted mechanical leg with a multi-stage energy lock mechanism. Background technique [0002] After a long period of evolution and development, the human body has evolved into an extremely energy-efficient system. Even then there is a considerable metabolic cost to walking. Most of the existing exoskeletons are self-powered, and the control system is used for feedback adjustment, but the general size and weight are relatively large, and the power supply is also a problem that cannot be ignored; unpowered exoskeletons can also reduce walking metabolism, but the existing There are very few studies on unpowered exoskeletons. The Massachusetts Institute of Technology redistributes the swing energy of the lower limb joints through springs, which can save walking metabolism with less, and provides new ideas for res...
