Detailed description of the invention
As shown in the figure, a kind of folded bicycle pull and push vehicle frame, comprise front bend pipe 1, back elbow 2 and motor 3, described front bend pipe 1 and back elbow 2 suitable, back elbow 2 inserts front bend pipe 1, described front bend pipe 1 arranges roller shutter cover 17, motor shaft 4 is connected with winding wheel 5, winding wheel 5 connects the front-end and back-end of back elbow 2 respectively by spiral 7, described winding wheel 5 arranges centre circle barrier 6, centre circle baffle 6 arranges the gear teeth 12, bearing pin 13 one end falls into wheel between cog, the other end falls into the shrinkage pool 14 set by back elbow 2, the split of described winding wheel 5 is set to two and half wheels, the side be connected with back elbow 2 front end forms one and half together with centre circle baffle 6 and takes turns and should half take turns and be fixedly connected with motor shaft 4, the side be connected with back elbow 2 rear end forms second half and takes turns and should half take turns and be provided with torsion spring 15 and be connected with motor shaft, described bearing pin 13 arranges spring 16, centre circle baffle 6 is circular, the described gear teeth 12 are uniformly distributed in the border of centre circle baffle, and the described gear teeth 12 press anticlockwise direction setting, the both sides of centre circle barrier 6 arrange spiral attachment point 8 respectively, the winding direction of both sides spiral 7 is contrary, the front end of described front bend pipe 1 arranges a sliding block 9, sliding block 9 is connected by spiral 7 with winding wheel 5, described front bend pipe 1 and back elbow 2 are plugged in together, form an overall bend pipe, described front bend pipe 1 connects front and arranges front-wheel 10, described back elbow 2 arranges trailing wheel 11.
During deployed condition, pull roller shutter to overlap 17 and make it slide on the bend pipe of entirety, slide into the seam of front bend pipe 1 and back elbow 2, the sense of outward appearance one is strong.
Centre circle barrier 6 can be divided into two winding wheel 5, and side spiral 7 is responsible for pulling reeve stroke, and opposite side spiral 7 is responsible for pulling retract stroke, make a clear distinction between good and evil, unlikely random line, twisted wire and beat mix; The attachment point 8 of both sides spiral, on same winding wheel wheel shaft, need not set up two-wheeled separately, saves accessory and also improves efficiency.
Sliding block 9 is in reeve stroke, and what be forced to moves to depths in front bend pipe 1 with back elbow 2; When deployment is desired, spiral 7 pulls sliding block 9 return, sliding block 9 again initiatively force back elbow 2 also together return.
Bearing pin 13 is set for the locking at deployed condition back elbow 2, bearing pin 13 insert shrinkage pool 14 stop back elbow 2 travel forward insert before bend pipe 1, alleviate motor 3 burden, added double insurance to back elbow 2.
The split of described winding wheel 5 is set to two and half wheels, the side be connected with back elbow rear end forms second half and takes turns and should half take turns and be provided with torsion spring 15, realize the delay effect of substep action, first locked by the rotating opening bearing pin 13 of the gear teeth 12 be fixedly connected with motor shaft 4 after motor 3 works, what connected by torsion spring 15 partly takes turns rotation work again, pull pulling and pushing of back elbow 2, this time difference achieves coaxially goes up the two and half substep actions taken turns.
Bearing pin 13 comprises an axle, and its two ends can around axle relative motion, and described bearing pin 13 arranges spring 16, for locking from released state self-return.
When vehicle is finished using and is needed stored collapsed, starter motor 3 power supply, motor shaft 4 rotates forward, winding wheel 5 is driven to rotate forward, the gear teeth 12 rotate, stir bearing pin 13 to move around axle, deviate from from shrinkage pool 14, back elbow 2 unlocks, because arrange the relation of torsion spring 15, now only there is the deformation of certain limit in torsion spring 15, second half is taken turns and not yet rotates, when motor shaft 4 is rotated further, second half is taken turns and is also driven to rotate, the spiral connecting back elbow 2 rear end is coiled on winding wheel 5, constantly tighten up, distance between winding wheel 5 and back elbow 2 rear end is constantly reduced, pull back elbow 2 constantly bend pipe 1 inside insertion forward accordingly, now sliding block 9 is positioned at the front end of back elbow 2, constantly headed in front bend pipe 1 inside, described winding wheel 5 arranges centre circle barrier 6, the both sides of centre circle barrier 6 arrange spiral attachment point 8 respectively, the winding direction of both sides spiral 7 is contrary, while the spiral 7 of bend pipe 2 rear end is constantly wrapped in and winding wheel is constantly shortened upon connection, spiral that be fixed on centre circle barrier 6 opposite side attachment point, that connect back elbow 2 front end is constantly loosened, and attachment point 8 is constantly lengthened with the distance of back elbow 2 front end sliding block 9.When folding putting in place, motor 3 arranges power-off according to predetermined stroke and stops operating.
When needing from folded state to launch, starter motor 3 power supply again, motor shaft 4 starts reversion according to predetermined set, winding wheel 5 is driven to reverse, the spiral connecting back elbow 2 front end sliding block 9 is coiled on winding wheel 5, constantly tighten up, distance between winding wheel 5 and back elbow 2 front end is constantly reduced, pull back elbow 2 constantly to home position return accordingly, same, be fixed on centre circle barrier 6 opposite side attachment point, the spiral connecting back elbow 2 rear end is constantly loosened, when launching to put in place, motor 3 arranges power-off according to predetermined stroke and stops operating, bearing pin 13 springs into shrinkage pool under the action of the spring 16 again, automatically reset, the relative position of locking back elbow 2, vehicle frame completes expansion.
Described front bend pipe 1 connects front and arranges front-wheel 10, and described back elbow 2 arranges trailing wheel 11, when folding putting in place, trailing wheel 11 fits in the side of front-wheel 10, forms stable floor-type support structure simultaneously, realizes folding rear standing support, and contractive effect is good, retraction volume is less.
It may be noted that; above-mentioned embodiment is only the utility model preferred embodiment; for those skilled in the art, under the prerequisite meeting utility model works principle, any equivalent or similar replacement all falls into protection domain of the present utility model.
