Specific embodiment

The purpose of this utility model, advantage and feature, will carry out figure by the non-limitative illustration of preferred embodiment below Show and explain.These embodiments are only the prominent examples using technical solutions of the utility model, all to take equivalent or wait Effect conversion and the technical scheme that formed, all fall within this utility model it is claimed within the scope of.

This utility model discloses a kind of reverse tricycle, 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.Headstock is provided with the main support 9 generally perpendicularly Support tube 13 and cushion rod 94, are provided with medicated cushion 95 on the cushion rod 94.Headstock support tube 13 is provided with headstock 1, the car 1 includes tap handle 11 and brake 12.The headstock support tube 13 is substantially vertical with the main support 9, and props up with the master Frame 9 is relatively fixed.Certainly, when the tricycle is foldable style, the headstock support tube 13 can also with the main support 9 It is folded against.The headstock support tube 13 be used to supporting headstock 1 and in which also slip be provided with telescoping tube 16, and rotationally set There is steering tube 14, the telescoping tube 16 is fixed or unclamped with the steering tube 14 by securing member 18.The top of the telescoping tube 16 Hold leading handle 11.Like the prior art, the tap handle 11 rotates and the steering tube 14 can be driven to rotate.It is described The bottom of steering tube 14 is provided with a swivel plate 15.The steering tube 14 and the combination of swivel plate 15 form rotation of the present utility model Actuator.

Link-type is provided between the T-shaped support 96 and front-wheel 92 and turns 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 a pivot 23, and the pivot 23 is arranged on described T-shaped On frame 96.

Specifically, with reference to shown in Fig. 4 and Fig. 5, the driving piece 22 includes the first pivot hole 221, and the pivot 23 is 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 pass 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 opposite side of the pull bar 21 of the symmetrical setting is on same connector 24.The connector 24 To be 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 it is 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 be 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 technologies for being formed Scheme, all falls within protection domain of the present utility model.
