The specific embodiment

As shown in Figure 1, a kind of two-player foldable formula tricycle described in the utility model, vehicle body is made up of vehicle frame 1, trailing wheel 2, driving device 3, two vehicle seat 4, the handlebar 5 of common double person bicycle, for increasing the stability of car load, front-wheel adopts the two-wheel parallel construction, affixed and reformulate the vehicle frame front end by steering column jacket 16, U type frame 15, spider 17, U type frame 15, spider 17 all adopt tubing commonly used in the present bicycle manufacture to make and adopt the mode of welding to carry out captive joint; Its steering hardware includes symmetrical two groups of front-wheels 6, steering shaft 8, connecting panel 9, telescopic lever 10, crank 11, front fork 12, front fork axle sleeve 13; Front fork axle sleeve 13 is affixed by galianconism 14 and hinge-type hinge box 7 one sides, hinge-type hinge box 7 opposite sides and vehicle frame front end are affixed, front fork 12 1 ends are installed front-wheel 6, the other end passes 13 formation of front fork axle sleeve and is rotationally connected, after hinge-type hinge box 7 was opened, front-wheel 6 can be respectively to folding 90 ° of proceeds posterolateral; Steering shaft 8, connecting panel 9, telescopic lever 10, the crank 11 that is fixed on the front fork 12 are formed connecting rod steering mechanism, and telescopic lever 10 two ends are movably hinged with connecting panel 9 and crank 11 respectively, and telescopic lever 10 can be locked by clip nut 18.

The running condition of two-player foldable formula tricycle described in the utility model as shown in Figure 2, both sides galianconism 14 forms fixing by hinge-type hinge box 7 locking backs with the vehicle frame front end during use, equicrural triangle distributed before three wheels of whole bicycle were, contact with ground formation face, can not produce easily and topple over, especially under the speed of riding situation slowly very, more can not produce this situation, captive joint with crank 11 by hold-down nut with front fork 12, connecting panel 9 forms connecting rod mechanism by telescopic lever 10 and crank 11, this moment, the length of telescopic lever 10 was locked by clip nut 18, during the handlebar left-right rotation, drive steering shaft 8 and on connecting panel 9 left-right rotation together, thereby connecting panel 9 further throw cranks 11 make front fork 12 drive front-wheels 6 left-right rotation, have realized the function that turns to of this bicycle like this.

The folded state of two-player foldable formula tricycle described in the utility model as shown in Figure 3, bicycle is when folding, cancel the locking of two hinge-type hinge boxes 7 respectively and unclamp clip nut 18 on the telescopic lever 10, and make its drive galianconism 14 and front-wheel 6 form folding to counter-rotating to proceeds posterolateral respectively, two ends pivotally attached telescopic lever 10 corresponding rotations this moment, extension bar withdrawal simultaneously, treat that both sides galianconism 14 revolves when turning 90 degrees backward, clip nut 18 is screwed, the length of locked telescopic lever 10, turn to reason the same during with use, still can realize the function that turns to of front-wheel certain angle this moment, make things convenient for the displacement of car load, the buckle straight-bar 19 that will be adsorbed on the front wheel guard side with magnet 20 in the time of will using when depositing takes off, rotate the back clasp joint on the mudwing of opposite side front-wheel 6 around hinge, form triangle with two telescopic levers 10 and be connected, avoid wheel that random rotation takes place.

The collapsible condensation of two front-wheels of this bicycle changes body shapes, wheel reversing when not using, also reduced width when reducing length over ends of body, reduce and deposit footprint, be convenient to family and pass on and indoor storage, during use by elevator, two front-wheels are opened to both sides, can not topple over easily, meet the notion of environmental protection, make things convenient for people especially friends' person in middle and old age trip or the needs of body-building.
