Show and explain.These embodiments are only the prominent examples for applying technical solutions of the utility model, all take equivalent or wait
Effect conversion and the technical scheme that formed, all fall within this utility model claimed within the scope of.
This utility model discloses a kind of tricycle with two front wheels, as shown in Figure 1, Figure 2 and Figure 3, including main support 9
And respectively positioned at two front-wheels 92 and a trailing wheel 93 of both sides before and after the main support 9, the front end of the main support 9 is provided with
T-shaped support 96, the both sides of the T-shaped support 96 are respectively symmetrically two front-wheels 92 of setting.Generally perpendicularly set on the main support 9
There are headstock support tube 13 and cushion rod 94, medicated cushion 95 is installed on the cushion rod 94.Headstock support tube 13 is provided with headstock 1,
The headstock 1 includes tap handle 11 and brake 12.The headstock support tube 13 is substantially vertical with the main support 9, and with institute
State main support 9 to be relatively fixed.Certainly, when the tricycle is foldable style, the headstock support tube 13 and the main support 9
Can also be folded against.The headstock support tube 13 is used for supporting headstock 1 and also slip is provided with telescoping tube 16 in which, and can turn
Steering tube 14 is provided with dynamicly, and the telescoping tube 16 is fixed with the steering tube 14 or unclamped by securing member 18.The telescoping tube
The leading handle 11 in 16 top.Like the prior art, the tap handle 11 is rotated and can drive 14 turns of the steering tube
Dynamic.The bottom of the steering tube 14 is provided with a swivel plate 15.It is new that the steering tube 14 and the combination of swivel plate 15 form this practicality
The rotary drive of type.
Link-type being provided between the T-shaped support 96 and front-wheel 92 and turning to bindiny mechanism, the steering bindiny mechanism includes
The rotary drive and the pull bar 21 of the symmetrical setting driven by the rotary drive, the one of two pull bars 21
End is individually fixed on a driving piece 22, and the driving piece 22 includes that a pivot 23, the pivot 23 are arranged on described T-shaped
On frame 96.
Specifically, in conjunction with shown in Fig. 4 and Fig. 5, the driving piece 22 includes that the first pivot hole 221, the pivot 23 are passed through
First pivot hole 221 is simultaneously located on the T-shaped support 96；The driving piece 22 also includes the second pivot hole 222, front axle
17 through second pivot hole 222 and penetrate to front-wheel 92 and make the front-wheel around 17 rotation of front axle；The driving piece 22 is also
Including the 3rd pivot hole 223, the pull bar 21 is articulated with the 3rd pivot hole 223.The driving piece 22 includes two the
One pivot hole 221, the T-shaped support 96 are located between described two first pivot holes 221, second pivot hole 222 and the
Three pivot holes 223 are located at the same side of the axis X formed by described two first pivot holes 221.
The driving piece 22 also includes the first fixing hole 224, for fixing front wheel brake part 19；The driving piece 22 is also wrapped
The second fixing hole 225 is included, for fixing front wheel guard 20.
The equal pivot of the opposite side of the pull bar 21 of the symmetrical setting is on same connector 24.The connector 24
For being mutually inserted symmetrical two halves formula structure together, the opposite side difference pivot of the pull bar 21 of the symmetrical setting exists
In the wherein half of the two halves formula structure；The two halves formula structure is plugged in together by a round pin 25；The rotary drive
Swivel plate 15 be erected on the connector 24, the two ends of the round pin 25 are stretched in the swivel plate 15.
As shown in Fig. 2 the pull bar 21 is less than the pull bar with one end and ground level of 24 pivot of the connector
The 21 one end and ground level with driving 22 pivot of piece, both have height difference H.When the rotation of the tap handle 11 can
During driving the steering tube 14 to rotate, the swivel plate 15 is rotated simultaneously.Due to the swivel plate 15 relative with connector 24
Fixed, axis of the connector 24 substantially also around the steering tube 14 is rotated, and then is pulled or promoted positioned at the connection
The pull bar 21 of 24 both sides of part.By taking Fig. 4 as an example, when tricycle needs, the pull bar 21 in figure promotes front-wheel 92 to rotate, specifically
, when pull bar 21 is subject to thrust, as the reason of pivot 23, the driving piece 22 also receive thrust, make driving 22 meeting of piece
Rotate counterclockwise along figure around axis X.As second pivot hole 222 and the 3rd pivot hole 223 are located at the axis X
The same side, i.e. front-wheel 92 can produce left-hand rotation.Likewise, another front-wheel 92 also can be in the pulling force infralevoversion of another pull bar 21.
In this moment, as there is the reason of certain frictional force and height difference H on wheel and ground, wheel, can first to the left when turning left
Incline, make turn inside diameter more smooth.It is same principle and opposite effect power that vehicle is turned right, and will not be described here.
Battery carrier 91 is additionally provided with the main support 9, allows tricycle of the present utility model to become electro-tricycle.
Certainly, in other embodiments, the folding stand can also connect the front-wheel mechanism and trailing wheel of ordinary bicycle
Mechanism forms ordinary bicycle.
This utility model still has numerous embodiments, all employing equivalents or equivalent transformation and all technology for being formed
Scheme, all falls within protection domain of the present utility model.
