Description
Technical field
The present invention relates to transportation equipment technical field, particularly relate to a kind of two monolateral folding bicycle of four connecting rods.
Background technology
Folding bicycle is in the market because of little, the easy to carry favor that is day by day subject to people of parking space.Existing folding bicycle is all generally that folding fastener is set on vehicle frame, thus by bicycle to folding up. ButBe that this laterally folded mode makes folding time long, the folding space of taking up an area is afterwards large, compact not.
Summary of the invention
Based on this, be necessary for prior art defect, provide short, the folding rear entirety of a kind of folding time tightGather, take up an area the little two monolateral folding bicycles of four connecting rods in space.
Its technical scheme is as follows.
A kind of two monolateral folding bicycles of four connecting rods, comprise can be longitudinal folding vehicle frame, this vehicle frame comprise head tube,Front-axle beam, central sill, seat pipe, linkage pull rod and be arranged at the lower deck carline of front-axle beam, central sill below, this head tube,Lower deck carline, central sill and front-axle beam are articulated and connected successively and form first four connection rod set; This front-axle beam, central sill, seatPipe and linkage pull rod are articulated and connected successively and form second four connection rod set; Each hinge horizontally set, this hingeAxis and the projection of rear wheel rotation axis in horizontal plane have angle.
The two monolateral folding bicycle frames of four connecting rods of the technical program are made up of two group of four connection rod set, head tube, underBackbar, central sill and front-axle beam are articulated and connected successively and form first four connection rod set, front-axle beam, central sill, seat pipe andLinkage pull rod is articulated and connected successively and forms second four connection rod set. And the hinge horizontally set of each hinged place,And the axis of hinge and the projection of rear wheel rotation axis in horizontal plane have angle, in folding process,Form dislocation, make folding after front-wheel and trailing wheel stagger, and front-wheel wheel axis and rear wheel rotation axis substantially heavyClose, make vehicle frame be able to carry out in himself plane longitudinal folding. When folding, in only seat pipe need being pressed toBeam, because seat Guan Jiyu central sill is hinged, is also connected with front-axle beam by linkage pull rod simultaneously, front-axle beam and central sillBe hinged, while therefore pressure after seat pipe, under the pulling of linkage pull rod, front-axle beam and central sill are drawn close folding mutuallyFolded (longitudinal folding) thus complete the folding of car load. Bicycle after folding, front-wheel and trailing wheel stagger mutually,The wheel axis of two-wheeled is located along the same line substantially. Front-axle beam and central sill are mutually folding, can effectively save space,While folding, only seat pipe need be pressed to trailing wheel simultaneously, convenient and swift.
In an embodiment, described head tube is provided with the first connecting portion and is arranged at this first connecting portion thereinThe connecting rod of below, central sill is provided with the second connecting portion and the 3rd connecting portion, and front-axle beam is provided with the 4th connecting portion,On seat pipe, be provided with the 5th connecting portion; This front-axle beam one end and the first connecting portion are hinged, and the other end and central sill are hinged;This lower deck carline one end and connecting rod are hinged, and the other end and the second connecting portion are hinged; This linkage pull rod one endBe hinged with the 4th connecting portion, the other end and the 5th connecting portion are hinged; One end of described seat pipe is articulated with theThree connecting portions. It is straight rectangular shaft-like that front-axle beam, central sill and connecting rod are all, and lower deck carline is inverted U-shaped shape, frontOne end and first connecting portion of beam are hinged, and an end of the other end and central sill is hinged.
In an embodiment, the hinge of the hinged place of described front-axle beam and central sill is arranged at a side of central sill therein,Be provided with this hinge phase heteropleural the locking device that front-axle beam and central sill are locked mutually. One end of front-axle beam with inOne end of beam is hinged, its hinged place with front-axle beam and the mutual locking device of central sill are separately positioned on central sill orThe both sides up and down of front-axle beam, hinged place is arranged on upside, and locking device is arranged on downside; Or, hinged placeArrange and downside, locking device is arranged on upside. Only locking device need be opened, can fold; WhenAfter whole car opened, buckle locking device rideable.
Therein in an embodiment, vehicle frame also comprise the monolateral front fork that is sheathed in head tube and with central sill oneThe monolateral back vent of moulding, described monolateral front fork and monolateral back vent heteropleural arrange. Monolateral front fork and monolateral back vent are allBe monolateral suspension, when car load is folded, monolateral front fork and monolateral back vent are symmetrical set, and entirety is tightGather, take up an area space and further dwindle.
In an embodiment, chain wheel one side is installed as driving side taking vehicle frame therein, its opposite side is non-drivingSide, described monolateral front fork is arranged at non-drive side. Monolateral front fork is arranged at and the driving side such as chain wheel or belt pulleyCorresponding opposite side, is able to trimming moment.
In an embodiment, vehicle frame also comprises the Five-way tube of horizontally set, described Five-way tube and central sill thereinBe fixedly connected.
In an embodiment, on described central sill, be provided with installed part therein, this installed part one end and Five-way tubeBe fixedly connected, the other end arranges the 3rd connecting portion.
In an embodiment, vehicle frame also comprises folding vertical tube therein, and described folding vertical tube is arranged at described headGuan Shang.
Advantage to technical solution of the present invention or principle describe below.
The two monolateral folding bicycle frames of four connecting rods of the technical program are made up of two group of four connection rod set, head tube, underBackbar, central sill and front-axle beam are articulated and connected successively and form first four connection rod set, front-axle beam, central sill, seat pipe andLinkage pull rod is articulated and connected successively and forms second four connection rod set. And the hinge horizontally set of each hinged place,And the axis of hinge and the projection of rear wheel rotation axis in horizontal plane have angle, in folding process,Form dislocation, make folding after front-wheel and trailing wheel stagger, and front-wheel wheel axis and rear wheel rotation axis substantially heavyClose, make vehicle frame be able to carry out in himself plane longitudinal folding. When folding, in only seat pipe need being pressed toBeam, because seat Guan Jiyu central sill is hinged, is also connected with front-axle beam by linkage pull rod simultaneously, front-axle beam and central sillBe hinged, while therefore pressure after seat pipe, under the pulling of linkage pull rod, front-axle beam and central sill are drawn close folding mutuallyFolded (longitudinal folding) thus complete the folding of car load.
