The working principle of the utility model is:

When folding ride, ride is in unfolded state, and ride front foot group 3 is in front, joint front foot connector 272 Opposite ground is fixing piece, starts being folded by single hand group 14, presses hand handle group 1 forward, and lower handle pipe 12 moves downward, and lock pin is pushed to push away Block 276 moves downward, and compresses joint spring 278, band movable joint lock pin 277 is from the sealed position 274 in guide groove end to guide groove 273 It sets, continues to rotate upper handle pipe 11 forward, joint lock pin 277 is moved to the front end of guide groove 273, and joint hand handle connector 275 pushes away Movable joint seating attachment couplings 279 fold group of seats 2 downwards together with hand handle group 1, post-tensioning carrying handle 511, and carrying handle 511 drives carrying handle Locking block 533 moves back, and is detached from locking block card slot 5331 and soldering pin 532, tension spring 534 is changed into tensional state from stationary state Process, lift carrying handle 511, the hinge of the composition of iron plate 531 connected with the rear foot by side food basket pipe 513, by ride rear foot group 4 to 3 direction of front foot group folds, i.e. realization bi-directional foldable folds；

When folding ride, ride is in unfolded state, and ride front wheels 3 press hand handle group 1, together at rear backward Above-mentioned working principle can also fold ride；

When ride to be unfolded, start being folded by single hand group 14, group 1, lower handle pipe 12 is pulled up upward handle, is drawn Pendulum lock pin pushing block 276 moves upwards, and joint spring 278 is driven to stretch, thus with movable joint lock pin 277 from the front end of guide groove 273 It moves backward, until continuing to rotate upper handle pipe 11 forward, making joint hand handle connector when sealed 274 position of position in guide groove end Group of seats 2 is unfolded backward together with hand handle group 1 in 275 pulling joint seating attachment couplings 279, pulls back rear foot group 4 and drives carrying handle 511 move downward, and tension spring 534 becomes stationary state process from tensional state dress at this time, and tension spring 534 pulls carrying handle locking block 533 It moves forward, when locking block card slot 5331 engages with soldering pin 532, food basket group 5 is in horizontal development state；

When ride expansion, seat fixing seat 241 is fixing piece relative to ground, starts backrest adjustment group 222, backrest tune Whole group 222 makes 2412 compression reseting spring 2414 of backrest tapered end and is detached from backrest regulation stall by tensing backrest bracing wire 223, to Preceding promotion backing tube 221 drives seat tubes 2413 to move backward, and seat guide channel plate 2411 is fixed on 2413 lateral surface of seat tubes On, seat tubes 2413 drive seat guide channel plate 2411 to move backward relative to seat fixing seat 241, adjust the angle of backing tube 221 Degree, while realizing that seat steadily moves backward, backing tube 221 is pushed backward, drives seat tubes 2413 to move forward, seat tubes 2413 drive seat guide channel plate 2411 to move forward relative to seat fixing seat 241, adjust the angle of backing tube 221, while seat Position is steady mobile forward；

When ride brakes, spin brake pedal 431 drives brake pipe 432 and brake jacking block 433 to rotate, brake Jacking block 433 is moved outward by the slope driving brake sliding block 433 on brake sliding block 434, and brake sliding block 433 compresses brake lever Spring 437, brake lever spring 437 push brake lever 435 that the effect of return spring 436 is overcome to move outward, are inserted into rear-wheel 411 The hole of cooperation, to play the role of brake；

When braking state to be released pushes ride mobile, direction spin brake pedal 431 contrary to the above drives brake Pipe 432 and the brake direction contrary to the above of jacking block 433 rotate, and push brake lever 435 inwardly under the action of return spring 436 Movement achievees the effect that release braking state, brake lever 435 overcomes brake lever spring to be detached from the hole of the cooperation of rear-wheel 411 437 effect pushes brake sliding block 434.

It is obvious to a person skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and And without departing substantially from the spirit or essential attributes of the utility model, it can realize that this is practical new in other specific forms Type.Therefore, in all respects, the present embodiments are to be considered as illustrative and not restrictive, this is practical new The range of type is indicated by the appended claims rather than the foregoing description, it is intended that containing for the equivalent requirements of the claims will be fallen in All changes in justice and range are embraced therein.It should not treat any reference in the claims as limiting Related claim.
