所述电机 83采用无刷直流电机， 其能源由蓄电池 81提供， 并通过电子 控制器控制； 电机上还设有太阳能充电接口 （未图示）， 用于外接太阳能电 池， 如外接薄膜太阳能电池板， 该种电池板具可折叠、 可褶皱而不损坏等 特性， 骑行时可将其折叠收于车架内包 11中； 需要充电时， 只需将其摊开 于太阳光下即可进行充电。 所述电子控制器安装于车把 2内， 用户可直接通 过旋转手把 21控制电机 83， 进而控制车速， 实现无极变速。 The motor 83 adopts a brushless DC motor, the energy source thereof is provided by the battery 81, and is controlled by an electronic controller; the motor is further provided with a solar charging interface (not shown) for external solar cells, such as an external thin film solar panel. The battery panel has the characteristics of being foldable, wrinkle-free and not damaged, and can be folded into the frame 11 when riding; when charging, it can be charged by simply spreading it under the sunlight. . The electronic controller is mounted in the handlebar 2, and the user can directly control the motor 83 by rotating the handlebar 21, thereby controlling the vehicle speed to achieve infinitely variable speed.
本实施例的多功能可折叠便携式自行车， 通过安装驱动机构以电动模 式骑行， 更加有利于用户长途野外旅游。 The multifunctional foldable portable bicycle of the embodiment is mounted in an electric mode by installing a driving mechanism, which is more advantageous for the user to travel long distances in the field.
本发明的多功能可折叠便携式自行车可配备可拆卸 GPS导航仪， 利于 旅行导航功能； 此外还可体现宣传奥运精神： 在前轮上添加可拆卸蓝色圆
圈， 后轮添加可拆卸红色圆圈， 将前轮及后轮分别涂成黄色及绿色， 车架 涂成黑色， 即成为奥运的五环标志， 可利于宣传奥运精神， 提倡运动健身， 绿色出行和低碳出行的理念。 The multifunctional foldable portable bicycle of the invention can be equipped with a detachable GPS navigator, which is beneficial to the travel navigation function; and can also embody the spirit of promoting the Olympics: adding a detachable blue circle on the front wheel Circle, the rear wheel adds a detachable red circle, the front and rear wheels are painted yellow and green respectively, and the frame is painted black, which becomes the Olympic five-ring mark, which can promote the Olympic spirit, promote sports and fitness, green travel and The concept of low carbon travel.
综上所述， 本发明的多功能可折叠便携式自行车， 采用圆形车架及内 外包装置， 时尚美观， 可便于携带小孩及随身物品， 更加方便出行， 折叠 时可将前后轮折叠平行装于车架内， 通过外包将折叠后的自行车容置其中， 提高了外在整体美观性， 及使用支架轮滑动利于推拉， 便于携带； 此外， 本发明可采用自行车模式骑行， 也可通过装设驱动机构以电动车模式骑行， 其驱动机构具自发电功能， 且可用于其它携带的用电设备的紧急充电， 更 加实用方便， 利于长途骑行。 In summary, the multifunctional foldable portable bicycle of the present invention adopts a circular frame and an inner wrapping device, is fashionable and beautiful, can be convenient for carrying children and personal belongings, and is more convenient to travel. When folded, the front and rear wheels can be folded in parallel and mounted in parallel. In the frame, the folded bicycle is accommodated therein by outsourcing, thereby improving the overall aesthetic appearance, and using the bracket wheel sliding to facilitate pushing and pulling, which is convenient to carry; Moreover, the present invention can adopt bicycle mode riding or installation. The driving mechanism is driven in the electric vehicle mode, and the driving mechanism has a self-generating function, and can be used for emergency charging of other portable electrical equipment, which is more practical and convenient, and is advantageous for long-distance riding.
