For flywheel 30, the centre of front-wheel 2 is arranged in the flywheel；Second driving mechanism further includes steel wire 29, the steel wire 29
One end is connect with the top of arc-shaped plate 20, and the other end of the steel wire 29 is connect with the flywheel 30；29 1, the steel wire
Divide and is wound on the arc groove.One reset spring is installed on the flywheel.When user is driven using the second driving mechanism
When tricycle moves ahead, user pulls back rocker arm by hand handle, and rocker arm drives arc-shaped plate 20 to move, and then is wound on arc groove
On steel wire drive flywheel turns, and then drive front-wheel rotate forward, then reset spring resets rocker arm, then proceedes to pull
Rocker motion.
Wherein, return spring 28 is provided in the connecting shaft at rocker arm interconnecting piece both ends, 28 sets of return spring connect in rocker arm
So that it is convenient to which rocker arm resets in the cylindrical shaft at portion both ends.Specifically, the effect of setting reset spring is in order to without using shaking
In the case that arm is driven, the state for making rocker arm be kept upright always, when using the second driving mechanism drive when, user to
The back lower place pulls rocker arm, and when then rocker arm restores upright, due to the setting of reset spring, when rocker arm restores upright, user makes
Power is smaller, even if user does not exert oneself, rocker arm can also self-resetting.I.e. rocker arm is that the principle of lever laborious to use is transported
Dynamic.
Wherein, the first fixing piece and the second fixing piece, the first fixing piece and the second fixing piece are provided on pivot link 12
The both sides of tricycle this body support frame 1 are set, and the shortest distance apart from tricycle this body support frame 1 is equal；First drive link
One end is fixedly connected with the first fixing piece；The other end of first drive link is provided with the first annulus 21, and the first annulus 21 is arranged
On the first U-shaped connector；Second drive link one end is fixedly connected with the second fixing piece；The other end of second drive link is set
It is equipped with the second annulus 22, the second annulus 22 is set on the second U-shaped connector.
Wherein, described this body support frame of tricycle 1 further includes seat 25, the seat 25 it is height-adjustable.
Wherein, backrest 26 is provided on the seat 25, the backrest 26 is set as arc according to body mechanics；It is described to lean on
Back 26 it is height-adjustable.
Wherein, this body support frame of tricycle 1 further includes loading frame, and loading frame is arranged between two rear-wheels 3.
Wherein, the first foot pedal 7 includes the first bottom plate, and the heel place of trampling of the first bottom plate is provided with the first heel and tramples
Plate, the first heel pedal and the first bottom plate are in 15 degree to 30 degree of angle；It is set between first heel pedal and the first bottom plate
It is equipped with spring；Second foot pedal includes the second bottom plate, and the heel place of trampling of the second bottom plate is provided with crus secunda with pedal, and second
Heel pedal and the second bottom plate are in 15 degree to 30 degree of angle；Crus secunda is with being provided with bullet between pedal and the second bottom plate
Spring.In this way be arranged foot pedal, ride the tricycle when, forefoot is easier to make power.
When being ridden instead of walk using tricycle of the invention or body-building, user can step on the of the first driving mechanism by foot
Both one and/or second motion of foot, it can also be moved by pulling the rocker arm 19 of dynamic second driving mechanism, or using
In conjunction with mode move.Two kinds of motion modes of tricycle are told about separately below.
When stepping on first and/or the second motion of foot of the first driving mechanism by foot, user can step on first simultaneously
Foot pedal 7 and the second foot pedal, can also step in the first foot pedal 7 and the second foot pedal one drive tricycle to advance,
Accordingly even when the only convenient people of one leg can also ride tricycle of the invention, when forefoot firmly step on the first foot pedal 7 and/
Or when the second foot pedal, driving pivot link 12 rotates down certain angle, when the first foot pedal 7 and/or the second foot pedal are multiple
When position, pivot link 12 resets simultaneously, and then successively drives in the first active connecting rod 13 and the second active connecting rod 16, first
Between connecting rod 14 and the second middle brace rod 17, the first driven connecting rod 15 and the second driven 18 front and back of connecting rod it is reciprocal, due to
First U-shaped connector/second U-shaped connector one end is fixedly connected with the middle position of preceding sprocket wheel 9, the other end and tricycle ontology
Bracket 1 is rotatablely connected, therefore with the first driven 18 front-rear reciprocation movement of connecting rod of driven connecting rod 15/ second, the first U-shaped connects
Fitting/second U-shaped connector circumferentially moves, and then preceding sprocket wheel 9 is driven to rotate, the intermediate position of two rear-wheels 3 of tricycle
It is connected by support shaft and the intermediate position of rear sprocket wheel 10, when sprocket wheel 10 rotates after driving because of sprocket wheel 9 before this, rear sprocket wheel 10 band in turn
Dynamic two rear-wheels 3 of tricycle rotate, and then entire tricycle is driven to advance.
It should be noted that the first foot pedal 7 of the invention, the second foot pedal step on flowing mode stepping on similar to sewing machine
Plate, i.e. the first foot pedal 7, the second foot pedal can be trampled with forefoot forward downward, can also be trampled with heel to the back lower place,
And then move reciprocatingly, centrifugal movement partially is done with spring (with spring section) before making the first drive link, increases front and back
The quick movement resetted.
When using this driving method, user by riding the tricycle, can take exercise user waist,
Muscle, joint, the ligament at the positions such as abdomen, neck, back, foot, ankle etc..
When rocker arm 19 by pulling dynamic second driving mechanism is moved, user pulls back rocker arm 19, drives circle
Arc panel movement, and then the steel wire 29 being wound on arc groove is driven to move, steel wire 29 drives flywheel 30 to rotate, and then before front-wheel 2
Into, it is successively reciprocal in this way to move rocker arm 19 backward, then reset, front-wheel 2 just goes ahead rotation, this driving method,
It can be used the only convenient people of hand always.
Using this kind of driving method, user by riding the tricycle, can take exercise the waist of user, abdomen, neck,
Muscle, joint, the ligament at the positions such as back, hand, arm etc..
In addition, double drive health care tricycle of the invention is especially suitable since the elderly is not suitable for significantly moving
Physical fitness of old man is closed to use.
As described above, double drive health care tricycle of the invention moves tricycle by way of double drive, into
And achieving the effect that body-building, and tricycle disabled person of the invention can also be easy to ride, use scope is wider.
It should be understood that above-mentioned specific embodiment of the invention is used only for exemplary illustration or explains of the invention
Principle, but not to limit the present invention.Therefore, that is done without departing from the spirit and scope of the present invention is any
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.In addition, appended claims purport of the present invention
Covering the whole variations fallen into attached claim scope and boundary or this range and the equivalent form on boundary and is repairing
Change example.
