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.But 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, short, the folding rear overall compact of a kind of folding time is provided, takes 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 bicycle of four connecting rods, comprise can be longitudinal folding vehicle frame, this vehicle frame comprises head tube, front-axle beam, central sill, seat pipe, linkage pull rod and is arranged at the lower deck carline of front-axle beam, central sill below, and this head tube, lower deck carline, central sill and front-axle beam are articulated and connected successively and form first four linkage rod group; This front-axle beam, central sill, seat pipe and linkage pull rod are articulated and connected successively and form second four linkage rod group; Each hinge horizontally set, the axis of this hinge and the projection of rear wheel rotation axis in horizontal surface have angle.
The two monolateral folding bicycle frames of four connecting rods of the technical program are made up of two group of four linkage rod group, head tube, lower deck carline, central sill and front-axle beam are articulated and connected successively and form first four linkage rod group, and front-axle beam, central sill, seat pipe and linkage pull rod are articulated and connected successively and form second four linkage rod group.And the hinge horizontally set of each hinged place, and the axis of hinge and the projection of rear wheel rotation axis in horizontal surface have angle, in folding process, form dislocation, folding rear front-wheel and trailing wheel are staggered, and front-wheel wheel axis and rear wheel rotation axis overlap substantially, make vehicle frame be able to carry out in himself plane longitudinal folding.When folding, only seat pipe need be pressed to central sill, because seat Guan Jiyu central sill is hinged, also be connected with front-axle beam by linkage pull rod simultaneously, front-axle beam and central sill are hinged, therefore while pressure after seat pipe, under the pulling of linkage pull rod, front-axle beam and central sill are mutually drawn close folding (longitudinal folding) thereby are completed the folding of car load.Bicycle after folding, front-wheel and trailing wheel stagger mutually, and 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 the pipe link of this first connecting portion below therein, and 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, is 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 pipe link are hinged, and the other end and the second connecting portion are hinged; This linkage pull rod one end and the 4th connecting portion are hinged, and the other end and the 5th connecting portion are hinged; One end of described seat pipe is articulated with the 3rd connecting portion.It is straight rectangular shaft-like that front-axle beam, central sill and pipe link are all, and lower deck carline is inverted U-shaped shape, and an end and first connecting portion of front-axle 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, is provided with this hinge phase heteropleural the latching device that front-axle beam and central sill are locked mutually.One end of front-axle beam and an end of central sill are hinged, its hinged place and the both sides up and down that front-axle beam and the mutual blocking device of central sill are separately positioned on to central sill or front-axle beam, and hinged place is arranged on upside, and blocking device is arranged on downside; Or hinged place arranges and downside, blocking device is arranged on upside.Only blocking device need be opened, can fold; After whole car opened, buckle blocking device rideable.
Therein in an embodiment, vehicle frame also comprise the monolateral front fork that is sheathed in head tube and with the integrated monolateral back vent of central sill, described monolateral front fork and monolateral back vent heteropleural arrange.Monolateral front fork and monolateral back vent are all monolateral suspension, and when car load is folded, monolateral front fork and monolateral back vent are symmetrical set, and overall compact is taken up an area space and further dwindled.
In an embodiment, chain wheel one side is installed as drive side take vehicle frame therein, its opposite side is non-drive side, and described monolateral front fork is arranged at non-drive side.Monolateral front fork is arranged at the opposite side corresponding with the drive side such as chain wheel or Pulley, is able to balancing torque.
In an embodiment, vehicle frame also comprises the Five-way tube of horizontally set therein, and described Five-way tube and central sill are fixedly connected.
In an embodiment, on described central sill, be provided with fabricated section therein, this fabricated section one end and Five-way tube are fixedly connected, and 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 in described head tube.
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 linkage rod group, head tube, lower deck carline, central sill and front-axle beam are articulated and connected successively and form first four linkage rod group, and front-axle beam, central sill, seat pipe and linkage pull rod are articulated and connected successively and form second four linkage rod group.And the hinge horizontally set of each hinged place, and the axis of hinge and the projection of rear wheel rotation axis in horizontal surface have angle, in folding process, form dislocation, folding rear front-wheel and trailing wheel are staggered, and front-wheel wheel axis and rear wheel rotation axis overlap substantially, make vehicle frame be able to carry out in himself plane longitudinal folding.When folding, only seat pipe need be pressed to central sill, because seat Guan Jiyu central sill is hinged, also be connected with front-axle beam by linkage pull rod simultaneously, front-axle beam and central sill are hinged, therefore while pressure after seat pipe, under the pulling of linkage pull rod, front-axle beam and central sill are mutually drawn close folding (longitudinal folding) thereby are completed the folding of car load.Bicycle after folding, front-wheel and trailing wheel stagger mutually, and 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.
