Abstract

The invention provides a space bicycle used in space travel. The space bicycle is composed of a base, a stand column, suspension arms, a suspension arm support, a seat, pedal driving devices, a transmission and speed variation device and the like. The pedal driving devices drive the suspension arm support to rotate around a wheel axle, the suspension arm support drives the suspension arms to rotate to generate inertial centrifugal force, the suspension arms are gradually unfolded outwards under the action of the inertial centrifugal force, and therefore artificial gravity is applied to the human body. The space bicycle saves energy, protects the environment, is small in occupied space, is simple and convenient to operate, achieves the effect that physical exercise and artificial gravity practice are carried out at the same time, can effectively and comprehensively resist against a weightlessness effect, and improves exercise efficiency.

Description

Space bicycle

Technical field

The present invention relates to a kind of can simultaneously having sports and the space bicycle of artificial gravity training.

Background technology

Weightlessness during space travel can cause that adaptive change appears in each system of human body, comprises cardiovascular dysfunction, muscular atrophy and bone loss etc., threatens spacefarer's health and safety.In the counterplan of taking at present, physical training is the most the most frequently used counter measure.Bicycle ergometer is a kind of exercise method of extensive use in space travel, bicycle ergometer is a kind of device that can step that is similar to bicycle type, by bicycle ergometer, is trained and can be alleviated cardiovascular dysfunction and the muscular atrophy that weightlessness causes.And in long duration space flight, set up the most effective comprehensive measure that artificial gravity environment is considered to resist weightlessness effect, can fundamentally eliminate weightless adverse effect.But, in view of the particularity of space flight environment and the restriction in space, still in space station, be not equipped with so far artificial gravity equipment.The artificial gravity equipment that research and development are adapted at applying in space travel is very necessary.

Summary of the invention

The object of this invention is to provide a kind of can simultaneously having sports and the space bicycle of artificial gravity training of being suitable for applying on space station.

The technical solution used in the present invention is: space bicycle is partly comprised of base, column, arm, arm support, seat, foot drive device, transmission and speed change gear etc., by foot drive device, drive arm support to rotate around wheel shaft, arm support drives arm to rotate and produces centrifugal inertial force, arm abduction gradually under the effect of centrifugal inertial force, thus make human body be subject to artificial gravity effect.

The invention has the beneficial effects as follows: spacefarer utilizes space bicycle to perform physical exercise in space travel, realized and in physical training, carried out artificial gravity training, effective all-out confrontation weightlessness effect, tempers efficiency higher, and effect is more obvious.Space bicycle relies on manpower to drive, and energy-conserving and environment-protective, occupy little space, easy and simple to handle.

In figure, 1. arm support, 2. gear, 3. transmission and speed change gear, 4. wheel shaft, 5. arm, 6. support, 7. display, 8. brake handle, 9. handrail, 10. seat, 11. supports, 12. foot drive device, 13. pedals, 14. columns, 15. bases.

The specific embodiment

As shown in Figure 1, space bicycle is partly comprised of base 15, column 14, arm 5, arm support 1, seat 10, foot drive device 12, transmission and speed change gear 3 etc.Two arms 5 are cylindric rigid structure, and the upper end of arm 5 is arranged on the two ends of arm support 1 by bearing, and arm 5 can abduction.Arm support 1 is rectangular-shaped rigid structure, and the bottom center of arm support 1 is connected with wheel shaft 4 by gear 2, and arm support 1 can rotate around wheel shaft 4, and wheel shaft 4 is fixed on the top of column 14.Column 14 is cylindric rigid structure, and lower end is fixed on base 15.Two foot drive device 12 are separately fixed at the lower end of arm 5, each foot drive device 12 connects two pedals 13, foot drive device 12 is connected with one end of transmission and speed change gear 3 by chain, transmission and speed change gear 3 are fixed in arm support, and the other end of transmission and speed change gear 3 is connected with gear 2.The chair back end of two seats 10 is fastenedly connected the top, side at arm 5 by support 6 respectively, and the seat end of seat 10 is fastenedly connected the bottom, side at arm 5 by support 11 respectively, and handrail 9 is connected by being fastenedly connected with seat 10.Four brake handles 8 are arranged on respectively the both sides, middle part of two arms 5, are connected, for retarding braking by steel wire with the brake lining on wheel shaft 4.Two displays 7 are separately fixed at the middle and upper part of two arm 5 sides, for showing the rotating speed of arm 5.

During use, one or two trainees sit up straight on seat 10 and with safety belt and fix, both hands are held respectively brake handle 8, both feet are placed on pedal 13 and firmly step, and by foot drive device 12, drive arm support 1 to rotate around wheel shaft 4, and arm support 1 drives arm 5 to rotate, increase along with rotating speed, arm 5 abduction gradually under the effect of centrifugal inertial force, thus make trainee be subject to artificial gravity effect, tempered again lower limb muscles simultaneously.Rotating speed is shown to trainee by display 7.
