The technical solution of the utility model is like this: a kind of trailing wheel reversing three-wheel vehicle, it is made up of frame part 35, drive element 37, commutation parts 34, brake part 36 and seat 33, drive element 37 is equipped with in frame part 35 front portions, frame part 35 postmedians are equipped with commutation parts 34, seat 33 is equipped with in frame part 35 back upper places, and brake part 36 is equipped with at frame part 35 middle parts.Described drive element 37 is made up of front-wheel 11, left threading 14, left axle sleeve 12, right threading 31, right axle sleeve 32, front wheel spindle 13, described left threading 14, left axle sleeve 12, front-wheel 11, right axle sleeve 32, right threading 31 are contained on the front wheel spindle 13 successively, and are fixedly connected on respectively by left axle sleeve 12, right axle sleeve 32 on the front fork 15 of frame part 35.Described frame part 35 is formed one-piece construction by front fork 15, crossbeam 17, seat frame 24, axle sleeve 26, and crossbeam 17 front ends are welded with front fork 15, and crossbeam 17 rear portions are welded with seat frame 24, and axle sleeve 26 is welded on the rearward end of crossbeam 17.Described brake part 36 by car stop 16, brake crank 18 forms, car is stopped and 16 is fixed on the described front fork 15, brake crank 18 is hinged on the left joystick 19, brake crank 18 is stopped by cable wire and car and 16 is connected.Described commutation parts 34 are made up of left joystick 19, left connecting rod 20, tailstock 23, rotating shaft 25, left rear wheel 21, left back wheel shaft 22, right back wheel shaft 27, off hind wheel 28, right joystick 30, right connecting rod 29, described left and right joystick 19,30 lower hinge are on crossbeam 17, flexibly connect by left and right connecting rod 20,29 between left and right joystick 19,30 lower ends and the tailstock 23, left rear wheel 21 is fixed on tailstock 23 left parts by left back wheel shaft 22, and off hind wheel 28 is fixed on tailstock 23 right parts by right back wheel shaft 27.Seat 33 is fixed by bolts on the described seat support 24.
Because the axle sleeve 26 of frame part 35 is to be enclosed within the rotating shaft 25 of commutation parts 34, current back promoted left and right joystick at 19,30 o'clock, drove left and right connecting rod 20,29 and seesawed, thereby make tailstock 23 left and right swings realize the purpose of commutation.When needing brake, the just stretchy cable wire of brake crank 18 of holding with a firm grip, 16 realization brakes thereby the pulling car is stopped.
Compared with prior art, the utlity model has following beneficial effect:
1, exterior design novelty is completely free of the design concept of common three-wheel vehicle, gives a kind of modish, leading sensation of people, is a kind of not only practicality but also later-model structure design.
2, owing to be that control lever and user's distance can be adjusted, and is particularly suitable for the child and uses by the commutation of joystick control trailing wheel.
3, consider safety factor, the seat of this three-wheel vehicle is overhead near especially, and the people sits onboard, and the center of gravity of car is very low, and the spacing between two trailing wheels is very wide again, so the degree of stability of three-wheel is big especially, guarantees that three-wheel vehicle can not overturn.It is a kind of toy for children of novelty, is again a kind of foolproof children's health and fitness facilities.
