Description

Scooter voluntarily

Technical field

The utility model belongs to self-propelling vehicle, particularly a kind of four-bar mechanism, gear-driven scooter voluntarily.

Technical background

At present, bicycle, motor bike remain one of main vehicle of trip, but completely are trouble in densely populated part car, are subjected to using restriction; Wear roller skate, step on slide plate and navigate between dormitory, dining room, each classroom having occurred the student in the campus,, saved the time, avoided the problem of bicycle parking difficulty so that finish the distance of 1～2Km; Roller skate, slide plate are only formed by axle and pulley simple combination, the Power train that does not have similar bicycle, go with people's leg power rationally, actv. is delivered on the driving wheel, not only improve speed but also save the strength, therefore roller skate, slide plate all can not be popularized as the vehicle, also do not see the scooter that contains similar bicycle power driving mechanism at present.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of small and exquisite nimble short distance traffic instrument scooter voluntarily is provided.

The technical scheme that the utility model technical solution problem adopts is: scooter mainly is made up of frame, leather sheath, preceding steamboat, gear, back bull wheel etc. voluntarily, is characterized in the frame front upper place soleaeform leather sheath being housed fixedly, and the front lower place is installed one and rotated steamboat; Central rack is movably installed with pedal, and the pedal left end is equipped with two torsion springs by pedal shaft and frame hinge joint on pedal shaft, by torsion spring pedal is upwards propped up, and brake rubber block is equipped with on the right top of pedal; Central rack bottom surface installation pendulum gear, left end is by pendulum gear wheel shaft and frame hinge joint, and it is hinged that upper right side passes through pole axle and pole and pedal; Frame, pedal, pole, pendulum gear constitute four-bar mechanism; The frame back lower place is by two bull wheels of bull wheel axle mounting, and bull wheel and steamboat are formed the slip wheels; On big wheel shaft, be connected with the overriding clutch inner ring by key, clutch outer is a gear, between gear and the big wheel shaft roller is housed, and between the scarce end face of roller and pedestal spring is housed, back-up ring and circlip are equipped with in the roller two ends, gear and the one-way driving mechanism of putting gear mesh formation power.

The beneficial effects of the utility model are: 1, the utility model is gently little, nimble, cooperate with leg can be higher excessively terraced bank, realize to turn, turn to; 2, simple in structure, cost is low, and is easy to carry, do not deposit difficult problem; 3, have sports and recreation effect concurrently, the big internal institution that suitable personnel concentrate uses; 4, effectively utilized people's walking, the upper and lower Wave energy when running, trample action meets the basic function of leg, can advance lastingly, can replace the big vehicle such as bicycle, motor bike in short distance.

The specific embodiment

Embodiment: with reference to accompanying

drawing

1,3,4, scooter mainly is made up of frame 1, leather sheath 2, pedal 5, pendulum gear 7, pole 8, bull wheel 12, steamboat 20 etc. voluntarily, in frame 1 front upper place leather sheath 2 is housed fixedly, leather sheath 2 is made calceoloid, makes footmuff enter the back and clamps automatically.A steamboat 20 that rotates is flexibly installed in the front lower place of frame 1, and steamboat 20 outsides are provided with steamboat cover 19, and steamboat 20 is installed in by antifriction-bearing box 21 on the steamboat axle 22 of captiveing joint with frame 1, and is fixing with nut 23.A pedal 5 is installed at the middle part of frame 1, and pedal 5 right-hand members are top-loaded with brake rubber block 10, and pedal 5 left ends can rotate up and down flexibly by pedal shaft 3 and frame 1 hinge joint, and torsion spring 4 is housed pedal 5 is upwards propped up.Pendulum gear 7 is installed in bottom surface, frame 1 middle part, and pendulum gear 7 left ends are hinged with frame 1 by pendulum gear wheel shaft 6, can rotate flexibly, and upper right side is hinged with pedal 5 by pole 8, pole axle 9.Frame 1, pedal 5, pole 8, pendulum gear 7 are formed four-bar mechanism.It is power wheel that two bull wheels 12 are installed in frame 1 back lower place, and power wheel can be made conter clockwise by working direction and rotate flexibly under the effect of overriding clutch.Bull wheel 12 is installed on the big wheel shaft 17, and big wheel shaft 17 is installed on the frame 1 by antifriction-bearing box 21, can rotate flexibly; Bull wheel 12 is loaded on big wheel shaft 17 two ends by wheel key 26 and connecting plate 24, and connecting plate 24 usefulness screws 27 and nut 28 are fixed on the disc of bull wheel 12, and big wheel shaft 17 two ends are fixing with connecting plate 24 with nut 25.Seal ring 29 and packing seal 30 are equipped with in antifriction-bearing box 21 both sides of bull wheel 12 inboards, and the outer rim of bull wheel 12 is equipped with bull wheel cover 11.Overriding clutch is connected with big wheel shaft 17 by key 14, clutch outer is a gear 13, and

gear

13 and 7 engagements of pendulum gear are equipped with roller 15 between gear 13 and the big wheel shaft 17, between the scarce end face of roller 15 and pedestal 18 spring 16 is housed, back-up ring 31, circlip 32 are equipped with in roller 15 two ends.

With reference to accompanying drawing 8, overriding clutch also can select the type of band ratchet 33 and ratchet 34.

Scooter is easy to use voluntarily, during use with footmuff in leather sheath 2, during with the downward pedal 5 of heel, this power is delivered to overriding clutch through pendulum gear 7, gear 13, again by clutch transmits to big gear wheel 12, big gear wheel 12 is rotated counterclockwise, carry out gliding motility.During heel lift, pedal 5 resets under the effect of torsion spring 4, and bull wheel 12 can not relatively rotate the clws that overriding clutch is made wide-angle, and scooter also can adopt the mode of roller skate, sliding slide plate to slide simultaneously voluntarily.
