Abstract

The utility model discloses a single-arm overturning or telescopic foldable bicycle, which comprise a front frame and a back frame connected with a front wheel and a back wheel, wherein the front and back frames are front and back frameworks which are transversely arranged; the front and back frameworks are connected by using a lockable rotating joint; the axle center of the rotating joint is parallel to revolving shafts of the front and back wheels; or the front and back frames are front and back frameworks which are arranged horizontally and transversely; corresponding framework pipes between the front and back frameworks are connected in a lockable telescopic insertion way; the front framework is a single-side framework, and the back framework is a double-side framework; or both the front and the back frameworks are single-side frameworks; or the front framework is a double-side framework, and the back framework is a single-side framework. Due to the adoption of the single-arm overturning or telescopic foldable bicycle, the front framework and/or the back framework are set as single-side frameworks under the condition of ensuring sufficient support stiffness, the weight of the foldable bicycle is further reduced, production cost is lowered, and convenience is brought to riding and carrying.

Description

Single arm type upset or telescopic folding car

(1) technical field:

The utility model relates to folded vehicle, particularly a kind of single arm type upset or telescopic folding car.

(2) background technology:

To the weak point of original side fold type folding car, the applicant has applied for " upset or fold concertina-wise car " patent of invention, has proposed a kind of collapsed compact; Volume is minimum and can stablize implementation; And simple in structure, folding very light and handy, quick and easy with expansion process, portable folded bicycle; Comprise the forward and backward vehicle frame that connects forward and backward wheel; Said forward and backward vehicle frame is bilateral horizontal forward and backward framework, is connected by the rotary joint that can lock between the said forward and backward framework, and the axis parallel of said rotary joint is in the turning cylinder of forward and backward wheel; Perhaps said forward and backward vehicle frame is the horizontal forward and backward framework of bilateral level, and the corresponding frame pipe between the said forward and backward framework adopts the flexible insertion that can lock to connect.

Find in the practice that the forward and backward vehicle frame of frame-type is not the most brief form, guaranteeing that forward and backward vehicle frame also can further be simplified to single arm type under enough hard conditions.

(3) utility model content:

The purpose of the utility model has provided a kind of single arm type upset or telescopic folding car of non-complete bilateral framed structure.

Can realize the single arm type upset or the telescopic folding car of above-mentioned purpose; Comprise the forward and backward vehicle frame that connects forward and backward wheel; Said forward and backward vehicle frame is horizontal front baffle and rear frame; Connected by the rotary joint that can lock between the said forward and backward framework, the axis parallel of said rotary joint is in the turning cylinder of forward and backward wheel, and perhaps said forward and backward vehicle frame is the horizontal forward and backward framework of level; Corresponding frame pipe between the said forward and backward framework adopts the flexible insertion that can lock to connect, and different is that front baffle and/or rear frame are monolateral framework.

The utility model has following several kinds of versions:

1, said front baffle is monolateral framework, and said rear frame is bilateral framework.

Said front baffle is that monolateral framework is put on a left side, or front baffle is that monolateral framework is put on the right side.

2, said front baffle is monolateral framework, and said rear frame also is monolateral framework.

Said front baffle and rear frame are the monolateral framework of homonymy, or front baffle and rear frame are the monolateral framework of offside.

3, said front baffle is bilateral framework, and said rear frame is monolateral framework.

Said rear frame is that monolateral framework is put on a left side, or rear frame is that monolateral framework is put on the right side.

Said monolateral framework should guarantee enough rigidity of support.

The advantage of the utility model:

Upset of the utility model single arm type or telescopic folding car are guaranteeing have under the condition of enough rigidity of support, and front baffle and/or rear frame are set to monolateral framework, have further alleviated the weight of folded bicycle, have reduced productive costs, are convenient to more ride and carry.

(5) specific embodiment:

Be described further below in conjunction with the technical scheme of accompanying drawing the utility model:

Upset of the utility model single arm type or telescopic folding car comprise the forward and

backward vehicle frame

3,4 that connects forward and backward

wheel

1,2; Front vehicle frame 3 connects the turning cylinder of front vehicle wheel 1 through the front fork of barre 8 (collapsible in the A point); Be equipped with on the barre 8 to the folding left and right handle 9 of the body of rod, vehicle seat 5 lock onto on the bar cover 10 through seat bar 6 plug-in mountings, and seat bar cover 10 is installed on the front vehicle frame 3; Back seat 7 rotation locks are on seat bar 6; Forward and backward vehicle frame 3, the folding and two kinds of versions of telescopic folding of upset are arranged between 4, existing upset folding structure mode with forward and backward single-wheel introduces, and is as shown in Figure 1.

Said forward and backward

vehicle frame

3,4 is horizontal front baffle of level and rear frame; Connect by the rotary joint that can lock (B point) between the said forward and backward framework; The axis parallel of said rotary joint (B point) is in the turning cylinder of forward and backward
