Abstract
The utility model relates to a foldable tricycle driven by a rider; after the tricycle is folded, the tricycle has small volume, simple manufacture for resetting structure, and adjustable resetting force. A front wheel, a tricycle frame assembly, a seat assembly and a back wheel assembly constitute the single-person back and seat type foldable tricycle. The front section beam of the tricycle frame assembly is hinged with a back section beam; the seat cushion of the seat assembly is hinged with a backrest; the seat sleeve of the seat assembly is hinged with the back section beam. A resetting spring between a back axle frame and the back section beam is two tension resetting springs which are symmetrically installed between the back axle frame and the back section beam through two groups of regulating screw rods, regulating nuts and blocking nuts.
Description
The utility model belongs to the wheel car that rider drives.
For ease of carrying with the level of comfort when improving rider and riding, separate several Foldable tricycles that continued on the foreign literature; Japan has then produced several tilting three-wheel vehicles.These Foldable tricycle volume after folding are still bigger; It is complicated that the tilting three-wheel vehicle then exists resetting structure to make, the shortcoming that reset force is not easy to regulate.
For providing a kind of volume after folding little, the resetting structure manufacturing is simple, and the adjustable folding tricycle of reset force proposes the utility model.
The utility model is made up of front-wheel, frame assembly, seat assembly and rear wheel assembly, frame assembly has the folding hinge of the tight mechanism with lock of leading portion beam, back segment beam and hinged leading portion beam and back segment beam, the hinge line of centers of folding hinge and the axis of front and rear sections beam are the space parallel line, and the distance between two lines is equal to or greater than the diameter of front and rear sections beam; Front-wheel is installed on the leading portion beam of frame assembly, and seat assembly is installed on the back segment beam of frame assembly.Seat assembly has an end and is hinged on the back segment beam, and the other end is enclosed within the seat sleeve pipe on the seat standpipe that seat is installed.The slideway shelf of band slideway is housed on the seat sleeve pipe, and damper spring is installed between seat sleeve pipe and the back segment beam through upper and lower drift bolt, unclamps that drift bolt can move in the slideway of slideway shelf on the jam nut, and seat is made up of seat cushion that is hinged and backrest; Rear wheel assembly has the middle part and constitutes swing bonded assembly flute profile rear axle support with the back segment beam, left and right symmetry is equipped with the retracing spring of band adjusting screw(rod) between flute profile rear axle support and the back segment beam, end at the flute profile rear axle support is equipped with driven wheel assembly, at its other end initiatively wheel assembly is housed, the chain baffle plate is equipped with in the drive sprocket both sides of wheels after initiatively.
Owing to the utlity model has three folding points, make the utility model volume after folding little, resetting structure of the present utility model adopts general extension spring, make simple, retracing spring has the screw rod of adjusting, is convenient to the adjusting of reset force, thereby reaches the utility model purpose.

Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model is made up of front-wheel 1, frame assembly 2, seat assembly 3 and rear wheel assembly 4, frame assembly 2 has the folding hinge 8 of the with lock tight mechanism 7 of leading portion beam 5, back segment beam 6 and hinged leading portion beam 5 and back segment beam 6, hinge 9 line of centerss of folding hinge 8 and the axis of leading portion beam 5 back segment beams 6 are the space parallel line, distance between two lines is equal to or greater than the diameter of front and rear sections beam 5,6, front-wheel 1 is installed on the leading portion beam 5, and seat assembly 3 is installed on the back segment beam 6; Seat assembly has an end and is hinged on the back segment beam 6, the other end is enclosed within the seat sleeve pipe 12 on the seat standpipe 11 that seat 10 is installed, the slideway shelf 14 of band stepped appearance slideway 13 is housed on the seat sleeve pipe 12, last drift bolt 16 and the following drift bolt 17 of damper spring 15 in being through stepped appearance slideway 13 is installed between seat sleeve pipe 12 and the back segment beam 6, the jam nut 18 that can lock, unclamp is housed on the last drift bolt 16, unclamp jam nut 18, last drift bolt 16 can move in stepped appearance slideway 13, and the other end of damper spring 15 is through drift bolt 16 is hinged with the back segment beam down; Seat 10 is made up of the seat cushion 20 and the backrest 21 that are hinged in hinge 19; The oscillating axle 22 that rear wheel assembly 4 has middle part and back segment beam 6 constitutes the flute profile rear axle support 24 of swinging auxiliary connections 23, left and right symmetry is equipped with the stretching retracing spring 27,28 of band adjusting screw(rod) 25,26 between flute profile rear axle support 24 and the back segment beam 6, setting nut 29,30 and locknut 31,32 are contained in respectively on the adjusting screw(rod) 25,26, driven wheel assembly 35 and wheel assembly 36 initiatively are housed respectively in the end 33,34 of flute profile rear axle support 24, chain baffle plate 38,39 are housed in the both sides of the sprocket wheel 37 of active wheel assembly 36.
In the time will carrying the utility model, the catch gear 7 that unclamps folding hinge 8 promotes leading portion beam 5, it is rotated, until closing up with back segment beam 6 with the direction that back segment beam 6 closes up around hinge 9 courts; Unclamp jam nut 18, and make drift bolt 16 slide into the upper end of stepped appearance slideway from the lower end of stepped appearance slideway 13 along stepped appearance slideway 13, meanwhile damper spring 15 swing and seat sleeve pipe 12 is swung around closing the direction of disturbing with the hinge court of back segment beam 6 with back segment beam 6 outwardly around following drift bolt 16, until close up locking jam nut 18 with back segment beam 6; Promote backrest 21 it is rotated with the direction that seat cushion 20 closes up around hinge 19 courts, until closing up with seat cushion 20.
