Abstract

The invention discloses a two-wheel electric bicycle which mainly comprises a bicycle body and standardized parts, wherein the bicycle body mainly comprises a frame, a battery case, a controller case, a chain cover, a front decorating plate, a rear decorating plate, a hanger panel, a protective pad and the like. The frame mainly comprises a head tube, an upper tube, a lower tube, a vertical tube, a loop lug, a bottom fork, a bottom fork axle tube, a vertical fork, a fork joint strip, a fork branch tube, a hanger branch tube, a hanger main tube and the like, wherein the lower tube includes a front lower tube and a rear lower tube, the frame and hangers are assembled and welded into a whole, the upper tube and the vertical fork are integrated into a coherent arc arch, the vertical tube spans over the middle upper part of the upper tube, and the rear lower tube, the bottom fork and the hanger branch tube are connected into a whole by an axis which is a tangent. The controller case is arranged behind the battery case, the battery case and the controller case are arranged in a space defined by the upper tube, the rear lower tube, the loop lug, the bottom fork and the vertical fork, the battery case is arranged at the middle part of the bicycle, and the battery case can be conveniently screwed (put) in or screwed (taken) out from the side of the frame just by rotating the battery case around a positioning arc surface at the lower part of the bicycle. All plastic parts are wrapped in a frame metal piece with a frame structure.

Description

technical field [0001] The invention relates to a novel two-wheel electric bicycle, in particular to a two-wheel electric bicycle adopting a new vehicle body, a novel battery box pick-and-place method and a positioning structure. Background technique [0002] At present, there are many varieties and types of known electric bicycles, each of which has many advantages, but also has some shortcomings. The car is now a mainstream model in the market, but it increases the load on the rear wheels and requires an additional positioning mechanism for the guide plate. The battery box must be lifted very high when taking and placing the battery box. The part is easily damaged, etc. Contents of the invention [0003] In order to overcome the deficiencies of the existing electric bicycles, the invention provides an electric bicycle, which adopts a novel vehicle body, a novel battery box pick-and-place method and a positioning structure. The battery box is in the middle of the car, a...
