Abstract

The invention provides a portable bicycle capable of being folded for multiple times. The portable bicycle consists of a handle transverse tube and handle vertical tube folding device, a handle vertical tube and front vertical tube folding device, a front vertical tube and a front fork tube folding device, a crossbeam connection locking device, a bicycle vertical tube rotating and locking device, a pedal crank rotating device and other more than 40 parts. By virtue of the mutual matching of the six folding mechanisms, the size of the foldable bicycle which is folded is smaller than that of similar foldable bicycles which are folded, three 14'-type bicycles can be placed in a car trunk, and two 16'-type bicycles can be placed in the car trunk.

Description

But the portable bicycle of multiple folding
One, technical field
The present invention relates to a kind of folding bicycle, but a kind of portable bicycle of multiple folding particularly.
Two, background technology
The current folded bicycle of seeing on the market is that two-fold is that trailing wheel is together with the front-wheel folding cutter mostly, and handlebar together with handle riser refolding to the centre of front and back wheel, so folding, although the length of car load has been dwindled, but the width after car load is folding has been thickeied, and how much not little volume is, if the material of folded bicycle is irony, heavier again after folding, so answer little, the lightweight purpose of volume with regard to the out of reach folded bicycle.And but the portable bicycle of the present invention's multiple folding is for being six folding, transverse tube with handle riser is collapsible and can 90-degree rotation, after 90 degree are folding, at handle riser and front standpipe pipe place, can fold back again, make a transverse tube and crossbeam overlapping, the width of car load after folding is less by 1/3rd than two-fold like this.Because front standpipe and front fork tube junction are provided with folding device, so front-wheel can rotate 70 degree backward, by the front-wheel folding in the snap ring below the bend pipe cant beam, car load length is just short by 1/3rd like this, on this basis at axis place trailing wheel toward front-wheel direction refolding once, car load length is just further dwindled so, time foldingly more than has in this way just finally reached the real little purpose of volume.As for weight and material, relation is arranged, if the present invention adopts approximately 8.5 kilograms of magnesium aluminum alloy complete vehicle weights, if adopt carbon fiber also with regard to the 4-5 kilogram weight.
Three, summary of the invention
But the portable bicycle of the present invention's multiple folding, mainly contain following parts and form on it; 1, automatic pressure-adjusting miniature inflating pump for bicycle (detailed content separately has patent application).2, bicycle handlebar horizontal tube rotation and latching device (patent application is separately arranged).3, handle riser and front device for folding stem.4, front standpipe and front fork tube folding rotary device.5, crossbeam folding rotary device.6, seat tube rotation and latching device.7, pedal crank rotation and latching device.In foregoing 1 and 2 be Mini-size inflation pump and transverse tube rotation and latching device all separately had to patent application, and this repeats no more.Below beam-folding device, seat tube rotation and latching device and pedal crank slewing arrangement are described below aspect 26S Proteasome Structure and Function:
1, the function of bicycle handlebar horizontal tube rotation and latching device is: at handle riser with in the middle of transverse tube, hand over the head place to install one and make can become flexible the special device that can screw to transverse tube, when advancing, bicycle just will be transferred to orthogonal state to transverse tube and handle riser, be also horizontality and then the manual bolts handle is screwed and makes it keep firm state, and in the time bicycle will being folded, just manual bolts is unscrewed and simultaneously will be the transverse tube 90-degree rotation, make it parallel with handle riser, and then handle riser and front device for folding stem are opened, now transverse tube is just folded into to the position parallel with crossbeam with handle riser simultaneously, in this way folding just avoided folding closing up of front and back wheel to increase the drawback of car load width because of therebetween one handlebar afterwards.
2, the function of handle riser and front device for folding stem is: by this device by handle riser with handle riser, be connected press transverse tube in the lump 90 degree to make it parallel with crossbeam backward, dwindled the width after car load folds.
3, front standpipe and front fork tube folding device, be that front wheel folding backward is laminated in snap ring preset under the bend pipe cant beam and fixes, and car load length has just shortened 1/3rd like this.
4, the position of beam-folding device is to receive the middle place of the car load length of poststack at front-wheel, when trailing wheel is folding, just make front and back wheel be closed up forward like this, the car load length of take after guaranteeing to fold is minimum, this folding device adopts two thimble connector, one sleeve pipe is together with the crossbeam solid welding, and process a slotted eye at blank area, and partly weld a T connector at another set of adaptor union, when T connector is folding, T connector inserts in the slotted eye of docking sleeve pipe, and then rotate an angle, now car load will dock sleeve pipe locking firmly, because the sleeve pipe that T connector is arranged and beam are so that the whole crossbeam that is threaded is very firm after being connected, as long as and the sleeve rotating that will be welded with T connector when opening during to former insertion state can open.
5, seat tube rotation and latching device, this device be with beam-folding device on a vertical line, when car load need to fold, beam-folding device is unclamped, bias on seat tube rotation and latching device is compressed to spanner to oppositely pulling simultaneously, spring in the rotary connection axle is also just pulled the tooth form engagement to unclamp, now seat tube just can rotate freely, coordinate beam-folding device just trailing wheel and front-wheel can be closed up, if open vehicle body as long as the bias compression spanner that vehicle frame is responsible on slewing arrangement compresses to contrarotation, whole vehicle body is just in aggregates securely, folded bicycle just returns to riding condition.6, pedal crank slewing arrangement, exactly the pedal crank in folded bicycle left side is made to fork-join rotatable folding type crank, this inboard crank adopts the bearing pin crotch to connect, when the needs car load is folding, in advance the crank lower end is rotated inward to an angle, just guarantee when front and back wheel is closed up that like this its spacing is minimum, also just reach folding after the volume width of car load width after more folding than folded bicycle of the same type be minimum purpose, the device effect after folding is also ideal.
