Described single-wheel pedestal is provided with seat, comprise seat board and feet on the described seat, described feet one end is coupling on the single-wheel pedestal, the other end of feet and described seat board rear end snap together, described seat board front end and described single-wheel pedestal are coupling together, and described collapsible inhibiting device is connected with the seat board front end by strut bar.
The both sides of described single-wheel pedestal are provided with backplate.
Compared with prior art, advantage of the present utility model is that when collapsible inhibiting device is opened two take turns pedestal and spider of single-wheel pedestal formation, but this moment, three-wheel vehicle was a motoring condition, and the three-wheel vehicle texture ratio is more firm.When collapsible inhibiting device was folding, single-wheel pedestal and tressel closed up, and have reduced the volume of three-wheel vehicle.Push hard a side of tressel this moment, detent mechanism on the tressel is shifted out from second knock hole, this moment, tressel rotated with the single-wheel pedestal, when the detent mechanism on the tressel moves to first knock hole, the single-wheel pedestal is in tressel folds into the right angle frame of secondary pedestal and main pedestal formation, the single-wheel pedestal has been done the rotation of 90 degree, wheel on the single-wheel this moment pedestal has also been done the rotation of 90 degree, wheel on the single-wheel pedestal has effectively utilized the space between two wheels of two-wheel pedestal between two wheels on the two-wheel pedestal.Body frame structure for automotive of the present utility model is firm, and the three-wheel vehicle volume is little, very convenient to carry after two-stage is folding simultaneously.
Loose pin falls in the knock hole in the effect of spring, and tressel and brace panel are fixed, and in the time of external force effect loose pin, loose pin can move between second knock hole and first knock hole.
After stretcher was holded up, circular shaft rotated 90 degree, made circular shaft drive positioning strip and rotated 90 degree, positioning strip is embedded in the positioning groove, thereby plays the effect of the rotation of restriction direction lever.Three-wheel vehicle after folding fully can work as the trailer or the go-cart of baggage container and be used, and after direction lever was fixed, it was more convenient to evade luggage.
When needs are folding with seat, seat board and feet to be thrown off, seat board and feet just can fold, and the volume of three-wheel vehicle is further reduced.
