Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described:

[0019] In the existing research, the spring mechanism can achieve the static balance of the mechanism system, that is, by adding auxiliary links and springs, the sum of the gravitational potential energy and elastic potential energy of the entire system remains unchanged, so that the mechanism system can maintain balance at any position , so it is also called a static balance mechanism. like figure 2 The spring mechanism shown, in the environment of 1g gravity on the ground, when mgr m When = kar (not counting the mass of the auxiliary connecting rod), at any angular position The vertical upward force F=mg that particle A is subjected to just cancels the gravity of particle A. Therefore, the static balance technology based on the spring mechanism is often used in the rehabilitation training of the lower limbs / arms or in simulating the microgravity environment on the g...

Abstract

The invention provides a gravity increase technology based on a spring mechanism. A core spring mechanism comprises a double-parallelogram mechanism, an upper limb connecting frame and a zero-elongation spring mechanism. A human body is fixedly connected with a framework through a bondage, the double-parallelogram mechanism is used for supplying the four-freedom-degree human body space walking range and providing the effect of a downward force; the upper limb connecting frame is used for fixing upper limbs of the human body and providing three rotation freedom degrees; and the zero-elongation spring mechanism is constant in pulling force along the vertical direction, and the gravity potential energy of the human body is increased through the elastic potential energy of the zero-elongation spring mechanism. Due to the adoption of the gravity increase technology, the gravity of the human body can be increased, and the contact force between the human body and the ground can be increased, so that an astronaut can move like on the surface of the earth under the micro-gravity environment, a resistance training method can be provided for the astronauts, or the sick and wounded can be passively rehabilitated.

Description

technical field [0001] The invention relates to a gravity increasing technology, in particular to a mechanism for increasing gravitational potential energy through elastic potential energy by using a spring mechanism. The utility model can be used not only for walking exercise of astronauts in outer space, but also for rehabilitation training of wounded and sick people. Background technique [0002] With the continuous deepening of my country's manned spaceflight project and the establishment of space laboratories, more astronauts will need to travel between the earth and space laboratories in the future to realize the rotation of space laboratories. However, the microgravity environment of the space laboratory is different from the ground environment familiar to humans. Long-term exposure to the microgravity environment will cause adaptive changes such as osteoporosis, skeletal muscle atrophy, and cardiovascular dysfunction, that is, space adaptation syndrome. These change...
