Problems solved by technology

Due to the large size, although the current folding bicycles can be stored in other means of transportation (such as cars), it is not convenient to carry them around.
In addition, in order to reduce the volume of the folded bicycle, wheels with a very small diameter are often used, which requires high smoothness of the road surface, otherwise the bumps will be serious and the riding will be very tiring

Embodiment 1

[0052] A portable bicycle, comprising a handlebar bar 2, a handlebar vertical bar 3, a handlebar 1, a front frame 5, a front fork 10, a connecting piece, a lower frame 16, a transmission mechanism, a front wheel 11 and a rear wheel 25; the front frame 5 and the front fork 10 are connected through the front axle 9, and the front fork 10 is connected with the underframe 16 through the front pipe 32 and the connector; the front frame 5 is provided with a rear wheel receiving groove 6 from top to bottom , the handlebar jack 14 and the front wheel receiving groove 7; the front wheel receiving groove 28, the cavity 12 and the rear wheel groove 73 are provided through on the described undercarriage 16; side; the rear wheel 25 is installed in the rear wheel groove 73 by the rear axle 26, and the two ends of the rear axle 26 are respectively provided with a flywheel 27; 4 connected, the handlebar cross bar 2 is located between the two handlebar vertical bars 3; it is characterized in t...

Embodiment 2

[0064] A kind of portable bicycle as described in embodiment 1, its difference is:

[0065] see image 3 , a locking key 8 is provided at the front of the front fork 10, and a locking block 36 is provided at the top of the front fork 10. When the front frame 5 is erected, the lower end of the front frame 5 is located between the locking key 8 and the locking block. between blocks 36. The advantage of the design here is that the fixing ability of the front frame 5 and the front fork 10 is enhanced, the safety performance is high, and it is easy to fold and unfold: when it is necessary to ride, the front frame 5 is rotated along the front axle 9 to the stopper 36 position, rotate the lock 8 to the position where it intersects with the front frame 5, so that the locking block 36 generates a pressing force on the front frame 5 so that the front fork 10 and the front frame 5 are fixed; when it needs to be folded During the present invention, the locking center 8 is rotated to a p...

Embodiment 3

[0067] A kind of portable bicycle as described in embodiment 1, its difference is:

[0068] see Figure 4 , 10 and 11, the upper end of the seat post 17 has an inclined end, when the seat post 17 is supported by the seat stay 29, the inclined end of the seat post 17 is horizontally arranged; the vehicle seat 43 includes a seat cushion frame 44 , seat cushion front part 53, seat cushion rear left part 55 and seat cushion rear right part 54, seat cushion frame 44 is connected with the inclined end of seatpost 17 through seat cushion frame shaft 57, seat cushion front part 53, seat cushion The rear left part 55 and the rear right part 54 of the seat cushion are connected with the seat cushion frame 44 through the seat cushion shaft 56 provided on the seat cushion frame 44; The shaft 56 is folded; when opened, the rear right part 54 of the seat cushion and the rear left part 55 of the seat cushion are deployed around the seat cushion axis 56; two arc grooves 68 with the seat cus...

Abstract

The invention relates to a portable bicycle, which is characterized in that a bicycle seat frame is arranged on a lower bicycle frame; the portable bicycle comprises a bicycle seat, a seat rod, a rear upper fork and a rear upper fork frame; the lower end of the seat rod is connected with the front end of a front wheel accommodating groove of the lower bicycle frame through a seat rod shaft; the bicycle seat is arranged at the upper end of the seat rod; the upper end of the rear upper fork is connected with the seat rod through a rear upper fork shaft; the rear upper fork frame is fixedly connected with the rear end of the front wheel accommodating groove on the lower bicycle frame; a front bicycle frame, the seat rod, the lower bicycle frame and the rear upper fork are respectively made of two rectangular parallel flat plates which are arranged symmetrically, so that a front bicycle wheel and a rear bicycle wheel are inserted in a gap between the parallel flat plates when the bicycle body is folded, therefore the volume of the folding bicycle is largely reduced. On the condition of adopting a bicycle wheel with a diameter of 10 inches, the folded size of the portable bicycle disclosed by the invention is 64 cm * 25.4 cm * 9.5 cm; and the portable bicycle has the advantages of light weight, high folding speed and convenience and safety for riding.

Description

technical field [0001] The invention relates to a portable bicycle and belongs to the technical field of folding bicycles. Background technique [0002] Bicycle is currently the most widely used personal transportation. In order to be easy to carry, people have invented various folding bicycles, and the technology adopted is generally folding in half, stretching and the like. Although the folded bicycle is much smaller in size, it is still too big to carry. For example, A-bike, which is currently considered to be the smallest folding bicycle in the world, see http: / / www.a-bike.com.cn, the folded volume is 67 cm x 30 cm x 16 cm (in the case of 6-hour wheels) ; other folding bikes are bulkier. Due to the large size, although the current foldable bicycles can be stored in other vehicles (such as automobiles), they are not convenient to carry around. In addition, in order to reduce the volume of the folded bicycle, wheels with a very small diameter are often used, so that th...
