Description

一种折叠便携式自行车  Folding portable bicycle
技术领域 Technical field
本发明涉及自行车技术领域， 具体的是一种折叠便携式自行车。 背景技术  The present invention relates to the field of bicycle technology, and in particular to a folding portable bicycle. Background technique
自行车和电动自行车是一种绿色环保的短距离交通工具， 虽然速度较低， 且行驶距 离有限， 但仍然得到大规模应用。 伴随着现代化进程， 人们的活动半径也越来越大， 农 村走向城镇化和城市规模扩大化，汽车、公交车、地铁等快速大容量交通工具越来越多。 美中不足的是， 开车出行， 城市越来越拥堵， 停车越来越困难， 尾气污染越来越严重， 油价也就越来越贵； 坐公交、 地铁出行， 则在家及工作单位与公交、 地铁站之间往往都 有一至几公里的距离， 目前的自行车和电动自行车因为不能随身携带， 如果在两头都骑 自行车， 则其保管存放和防盗是个难题， 有人曾经一年丢好几辆自行车。 如果靠两条腿 走路， 一般需要十几分钟到几十分钟， 劳累不说， 也浪费不少时间； 因此， 人们希望有 自行车或电动自行车能在折叠后随身或随车携带。  Bicycles and electric bicycles are green, short-distance vehicles that, despite their low speed and limited travel distance, are still being used on a large scale. Along with the modernization process, the radius of people's activities is also growing. The rural areas are becoming urbanized and the scale of the city is expanding. There are more and more fast and large-capacity vehicles such as automobiles, buses and subways. The fly in the ointment is that driving by car, the city is getting more and more congested, parking is getting more and more difficult, exhaust pollution is getting more and more serious, oil prices are getting more and more expensive; by bus, subway, home and work units with bus, subway station There are often distances between one and several kilometers. Currently, bicycles and electric bicycles cannot be carried around. If you ride bicycles at both ends, it is a problem to keep and store them. Some people have lost several bicycles a year. If you walk on two legs, it usually takes ten to several minutes. It is a waste of time and too much time; therefore, people want bicycles or electric bicycles to be carried or carried with them after folding.
国内外已经有成百上千项与折叠自行车或者折叠电动自行车相关的专利申请。 概 况起来， 按车架横梁折叠方式可分为两大类， 一种是绕水平轴折叠， 例如欧洲专利技术 A-bike, 是将前后轮之间的距离缩短以利携带， 折叠后的前后长度等于两个轮子的直径 之和， 一般在 50〜70cm 以上； 受折叠后尺寸所限， 轮子直径不能太大， 一般为 8〜10 英寸， 轮小则骑行阻力大。 另一种是目前最常见的横梁绕垂直轴旋转折叠， 如美国专利 Dahon折叠自行车， 为了避免车把（包括刹把）在折叠过程中和折叠后和自行车的车轮、 前叉、 后叉以及可旋转的脚蹬和链轮链条等人力驱动机构打架， 立管折叠器转轴的轴线 相对于水平面前进方向平行， 车把向下翻折后把立的轴线和头管的轴线之间的夹角都小 于 20度， 把横与地平面接***行， 影响了折叠后的尺寸、 规整性， 折叠后前后轮也无 法同轴， 只能用手提携带， 不能拖行； 类似的折叠电动车， 由折叠自行车增加电动装置 而成， 也存在同样的问题， 且因附加电池电机等较重的电动装置， 使得手提携带的难度 更大。 已有折叠自行车或者折叠电动自行车， 或多或少的存在如下缺陷：  There are hundreds of patent applications related to folding bicycles or folding electric bicycles at home and abroad. In summary, according to the frame beam folding method can be divided into two categories, one is folded around the horizontal axis, for example, the European patented technology A-bike, is to shorten the distance between the front and rear wheels to facilitate carrying, the length of the front and rear after folding It is equal to the sum of the diameters of the two wheels, generally 50~70cm or more; the size of the wheel is not too large, usually 8~10 inches, and the riding resistance is large. The other is the most common beam that is rotated around the vertical axis, such as the US patent Dahon folding bicycle, in order to avoid the handlebars (including the brake lever) during folding and folding and the bicycle wheel, fork, rear fork and The rotating pedal and the sprocket chain and other human driving mechanisms are engaged, the axis of the riser shaft of the riser is parallel with respect to the advancement direction of the horizontal plane, and the angle between the axis of the handlebar and the axis of the head tube is folded downward. Less than 20 degrees, the horizontal and horizontal planes are nearly parallel, which affects the size and regularity after folding. The front and rear wheels cannot be coaxial after folding. They can only be carried by hand and cannot be towed; similar folding electric vehicles, by folding bicycles The same problem arises with the addition of electric devices, and the heavier electric devices such as battery motors make it more difficult to carry them. There are already folding bicycles or folding electric bicycles, which have more or less the following defects:
1、 折叠后尺寸偏大， 也不够平整： 具有 12英寸前后轮的折叠车， 折叠后的外形尺 寸， 长 +宽 +高一般都在 1. 5米以上， 所占空间体积在 70L以上， 不利于存放； 平整度差， 携带时容易拖挂自己或他人的衣物， 因而有些城市的地铁或公交， 明文禁止携带折叠自 行车上车。 1. After folding, the size is too large and not flat enough: Folding car with 12-inch front and rear wheels, the folded outer dimensions, length + width + height are generally above 1.5 meters, occupying space above 70L, no Conducive to storage; poor flatness, easy to drag and drop clothes of yourself or others when carrying, so some cities or subways, expressly prohibited to carry folding Driving on the bus.
2、 折叠后不便拖行： 现有铝合金的折叠自行车 /电动自行车， 重量均在 10kg以上， 在折叠后前后轮通常无法同轴同步旋转， 携带时必须整体提起， 很不方便。  2, inconvenient tow after folding: Existing aluminum alloy folding bicycle / electric bicycle, the weight is more than 10kg, after folding, the front and rear wheels are usually not able to rotate coaxially synchronously, it must be lifted when carrying, it is very inconvenient.
