Description

The Electrical Bicycle vehicle frame

Technical field

The present invention relates to a kind of novel two-wheeled electric bicycle vehicle frame, especially adopt the novel two-wheeled electric bicycle vehicle frame of going up pipe, chain stay.

Background technology

At present, known Electrical Bicycle vehicle frame kind, type are a lot, and these cars all have many advantages separately; But also come with some shortcomings separately, for example: unreasonable structure, stress raisers are bigger; Strength at repeated alternation is lower, the inconvenience of getting on or off the bus, and the part adapted is inharmonious etc.

Summary of the invention

In order to overcome the deficiency of existing Electrical Bicycle frame, the present invention provides a kind of Electrical Bicycle vehicle frame, and this vehicle frame adopts later-model upper and lower pipe, chain stay, integral type clothes hanger structure.

The technical solution adopted for the present invention to solve the technical problems is: novel vehicle frame by the head pipe, down pipe, go up pipe, standpipe, center tap, preceding chain stay, back chain stay, upright fork, fork-join sheet, battery case guide plate, battery case base plate, clothes hanger foreleg, clothes hanger back leg, clothes hanger housing, bracket base, chain stay bridge tube, the upright bridge tube etc. pitched constitutes.The spindle axis of following pipe, preceding chain stay, clothes hanger back leg is continuous in, tangent the bowl type.The outstanding arch section in clothes hanger foreleg top can be carried automobile-used, and clothes hanger foreleg rear portion is connected with the clothes hanger housing, the lower end is connected with upright fork, and its spindle axis is parallel with standpipe.Adopting down, curved arc shape is managed down, go up pipe, preceding chain stay; Last pipe front end with down the pipe postmedian is connected, the upper end is connected with the standpipe middle part, in down the rear portion is connected with center tap, on manage upper surface and manage upper surface down, that the standpipe front surface is similar to coherent slyness is tangent, back chain stay front end is connected with preceding chain stay, the rear end is connected with the fork-join sheet; The rear end of following pipe is connected with the battery case base plate; Under manage the rear end and leave release part, center tap is positioned at the upper back of pipe down, bracket base is positioned at pipe posterior end down; The chain stay bridge tube is positioned at battery case base plate rear end, battery case guide plate lower end, and upright fork bridge tube is positioned at rear portion on the battery case guide plate.

The invention has the beneficial effects as follows, created later-model body frame structure for automotive.Last pipe upper surface and following pipe upper surface, standpipe front surface be approximate to link up slick and sly tangently, has improved strained condition, has reduced stress concentration, and the car load strength at repeated alternation is effectively improved.Simultaneously, the anterior space of last pipe and pipe top down, standpipe is bigger, and following pipe is lower, make get on or off the bus more convenient.Adopt forward and backward chain stay combined bottom fork structure, the spindle axis of preceding chain stay, clothes hanger leg is continuous, tangent, has improved the rear portion rigidity.The battery case base plate is connected with following pipe rear end, and the battery case base plate is connected with chain stay bridge tube and upright fork bridge tube with guide plate, has improved car load intensity and rigidity.Bracket base is positioned at pipe posterior end down, and is succinct, reliable.Manage the release part that the rear end is left down, can make things convenient for, smooth brake cable and the electric wire of deriving.The rear end of following pipe is connected with the battery case base plate, reinforcement each other.

This vehicle frame novelty, uniqueness, coordination, lucid and lively, smooth, attractive in appearance, generous, structural strength is high, in light weight, the life-span long, it is comfortable, easy to use to ride, and has distinct novelty, significant practicality, outstanding creativeness.
