Description

Multi-functional slide plate folding bicycle

Technical field

The utility model relates to a kind of multi-functional slide plate folding bicycle.

Background technology

Bicycle is a walking-replacing tool in earlier stage, and is simple in structure, function is dull.Nowadays bicycle has promoted into leisure and converter tools, so folding bicycle and Kickboard Scooter are come out one after another.Closely similar structure and function are arranged between bicycle and the Kickboard Scooter, but in the product on the market, both respectively are one, thereby function is still dull, and has caused the waste of resource

The utility model content

The purpose of this utility model is to overcome the above-mentioned time limit, and a kind of multi-functional slide plate folding bicycle is provided.

In order to achieve the above object, wheels before and after the utility model comprises, connect before and after between the wheels vehicle frame main beam, with preceding wheels bonded assembly handlebar, sit bag frame and chain drum group with back wheels bonded assembly; Be connected with foot-operated group on the chain drum group; Handlebar is provided with handle; Be provided with folder on handlebar, handle and the vehicle frame main beam; The vehicle frame main beam front end is provided with stretcher; Be connected by fork between back wheels and the chain drum group; Sit the bag frame and be provided with strut bar.

The utility model is 0 °～170 ° according to the pivot angle scope of the fork of right, and preferable range is 80 °～130 °.

Flexibly connect by rotating shaft between strut bar of the present utility model and the seat bag frame.

Owing to adopted such scheme, fork of the present utility model can be swung the chain drum group to the back upper place, and fix by strut bar, therefore have Kickboard Scooter and bicycle function in use, realize that a car has the difunctional of two kinds of cars, the enjoyment that both can enjoy slide plate also can be enjoyed the bicycle function of riding instead of walk.More apparent its unique function when child learns bicycle especially can be tempered its sense of equilibrium and is not easy to fall down when slide plate, when the sense of equilibrium can enter riding of bicycle on top of.In addition, it is many-sided folding to have implemented handle, handlebar, vehicle frame main beam etc. aspect folding, make the shared space of car after folding than Regular Bicycle after folding shared space littler.

The specific embodiment

As shown in fig. 1, the structural similitude of structure of the present utility model and bicycle, preceding wheels 8 are connected by vehicle frame main beam 9 between the wheels 17 with the back.Preceding wheels are captiveed joint with handlebar 20, and the handlebar interlude is provided with folder 18, and the top is connecting handle 21.The front end of vehicle frame main beam is provided with stretcher 10, and folder 19 is set, then connecting by midway location approximately and sitting bag frame 22, sit bag frame top and fixing seat bag 23, the angle of sitting between bag frame and the vehicle frame main beam rear is set with supporting seat 11, the position of sitting interlude on the bag frame is provided with strut bar rotating shaft 13, and this place rearward connects the strut bar that can swing 14.Also be arranged with fork rotating shaft 16 on the axle center of back wheels 17, it is connected with fork 15, and the other end of fork is connected with the axle center of chain drum group 12, and this place is also connecting foot-operated group 24.

As shown in Fig. 1 and Fig. 2, fork drives the chain drum group, can swing between supporting seat 11 and strut bar 14, and the scope of angle α is 0 °～170 ° between fork and the horizontal surface, and its preferable range is 15～130 °.

As shown in Fig. 3, Fig. 4 and Fig. 5, the folder on the utility model handle is three rotating shaft folder, and base 4 is provided with front rotary shaft 6, right spindle 7, left rotary shaft 5, and left and right sides rotating shaft is connected with the handle cross bar 1 of the right and left respectively.Be arranged with cover 2 on the axle of front rotary shaft, the folding of cover another side is by 3 controls of quick detach group.

Principle of work of the present utility model:

One. bicycle function and Kickboard Scooter function conversion:

Fig. 1: when the chain drum group was placed on the supporting seat, the utility model was to use as bicycle.

Fig. 2: remove the spacing and restriction insurance in below of strut bar 14, can make it to rotatablely move as circumference around rotating shaft 13, to the top spacing stop and carrying out spacing and the restriction insurance fixing; After removing the spacing of 11 pairs of forks 15 of supporting seat and restriction insurance, force in fork 15 and upwards make circular movement in the rear around fork rotating shaft 16, move to the rear and stop after spacing; At this moment, and remove the top restriction insurance of strut bar 14 and spacing, it makes circular movement around rotating shaft 13 to make member, to the below spacing stop and carrying out spacing and the restriction insurance fixing, play prevent chain drum group 12 and fork 15 to the front lower place rotatablely move spacing.This moment, the bicycle functions of use changed the functions of use of Kickboard Scooter into.

Otherwise, be the bicycle function then by the Kickboard Scooter functional shift.

Two. folding:

1. handle is folding:

Unclamp the handle of quick detach group 3 among Fig. 5, rotation quick detach group 3, releasing is to the insurance limit function of cover 2 and base 4, pass through the rotation of front rotary shaft 6 then, realize that rotation separately breaks away from action, promptly cover 22 separately breaks away from base 4, and quick detach group quick detach secondary insurance pivot pin gets loose, remove the rotary stopper of 2 pairs of handle cross bars 1 of cover, become the state of Fig. 6 and Fig. 7; Be rotated down cross bar 1 by left and right sides rotating shaft 5 and 7 again, realize the folding of handle cross handle.

2. vehicle frame is folding:

Fig. 9: open the doubling that rotation girder folder 19 is realized front and back wheels 8,17.

3. handlebar is folding:

Figure 10: open rotation handlebar folder 18 and realize handlebars and folding vehicle frame doubling, make handlebar and vehicle frame main beam 9 and be close together.

At this moment, finish whole folding processes of bicycle function.When opening, implement the counteragent of above folding process.
