Theoretical Design
1, transmission mechanism mechanical movement in leg designs
Leg exercise track is relatively simple, and it is about 30 ° that shank, which drives thigh to swing up and down amplitude, the revolution of leg rotation
Axis is in knee position on the upper side.Realization for the track, we plan the mechanical type using crank block originally, but consider
The factors such as noise and jerk, final we are changed to using crank and rocker mechanism, are equally able to achieve function, but relative to crank
Sliding block, rocker device effectively reduce the noise and jerk generated in rotation process.Keep the movement of mechanism more smooth, increases
The strong comfort of leg exercise.
As shown in Figure 6, it is known that rear axle is 320 with a distance from the rotating shaft of leg, i.e. AB=320mm sets the length of rocking bar
For 80mm, i.e. R=80mm, and because the rotation amplitude of leg is 30 °, i.e. α=30 °, and have
AD-AE=2R=160mm ... is 1.
AE=DF-80mm ... 2.,
Then had according to triangle theorem
AD2=AB2+BD2-2AB·BD·COS(105°)……③
AE2=AB2+BE2-2AB·BE·COS(75°)……
1. 2. 3. simultaneous can obtain:
FD=266mm BD=194mm, i.e. length of connecting rod are 266mm, and rocking bar length should be 194mm, and actual graphical is such as
Shown in Fig. 1
2, the mechanical movement of hand transmission mechanism designs
Consider human body practical structures feature, in order to keep our machine more comfortable, practical, we to the rotating shaft of hand into
It has gone change appropriate, rotary axial has been deflected 25 ° to leg on the horizontal level, and upward deflect on perpendicular
25 °, by controlling the shape of steel plate, our axis is mounted on to the angle of needs, as shown in Fig. 2, left-leaning inclined plate and riser it
Between angle, the angle between Right deviation inclined plate and riser be 155 °.
In this way, being easy to the activity in joint, while also ensuring in base when arm " entering water " and the angle on head is smaller
Under the premise of this motion profile is constant, the comfort of movement is improved.
The course of work of this example: people, which lies low, to lie on frame, and both hands hold the slide handle on bar, and both feet are placed on foot prop plate
On, catch slide handle that stock is driven to rotate clockwise around rotating shaft by arm, the rotation of stock passes through driving force universal
Shaft coupling is transmitted in the big sprocket wheel under frame of lying, and big sprocket wheel passes through chain-driving minor sprocket again and rotates, and driving force is transmitted to
Leg crank and rocker mechanism, moves crank and rocker mechanism, realizes leg footwork.Since the big sprocket wheel number of teeth is minor sprocket
3 times, big sprocket wheel rotation is turned around, minor sprocket triple turn, to realize the transmission ratio of hand and foot 1:3.
One embodiment of the present invention has been described in detail above, but the content is only preferable implementation of the invention
Example, should not be considered as limiting the scope of the invention.It is all according to all the changes and improvements made by the present patent application range
Deng should still be within the scope of the patent of the present invention.
