Foldable electric straight-beam bicycle with built-in batteries mounted in front-back split mode

Abstract

A foldable electric straight-beam bicycle with built-in batteries mounted in a front-back split mode is characterized in that a front frame cross beam 5 and a rear frame cross beam 11 are connected through a folding part 7 to form an integral frame cross beam, and the integral frame cross beam is parallel to the ground and is used for facilitating firmness and attractive appearance of a bicycle body. The central portion of the folding part 7 is hollow, a front battery 6 is mounted into the inside of the front frame cross beam 5 through the hollow portion of the folding part 7, and a rear battery 10 is mounted into the inside of the rear frame cross beam 11 through the hollow portion of the folding part 7. Due to the fact that the length of the rear frame cross beam is greater than that of the front frame cross beam and is about 2 times of the length of the front frame cross beam, and compared with an oblique-beam bicycle, the space for the batteries is increased by about 3 times, but the volume and the weight are not increased much and a riding journey is remarkably prolonged. The electric bicycle can be mounted into a luggage bag to be carried on the back after being folded, can be carried to a bus, can be ridden for a very-long-distance journey by means of the bus and facilitates environmental protection and road smoothness.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to a straight-beam folding electric bicycle with built-in batteries in front and back. Background technique [0002] With the strengthening of the importance of environmental protection, cities are in urgent need to reduce the emission of harmful gases, and the carbon monoxide, carbon dioxide, nitrogen oxides and organic waste gas emitted by cars have become the most serious pollution sources. In order to reduce urban smog and reduce air pollution Many cities have adopted measures to limit the number of cars traveling. Electric bicycles are clean energy, especially emerging batteries such as lithium batteries, fuel cells, and batteries combined with zinc or aluminum + air are more environmentally friendly. Electric bicycles are light and fast, and compared with cars, they do not block traffic roads, so There is a broad space for development; but the electric bicycles currently on the market a...
