Embodiment Construction

[0029] figure 1 An electric bicycle frame 1 according to the invention is shown, which is produced by joining together two corresponding plastic housing halves 2 , 3 . The electric bicycle frame 1 has a receptacle 12 for the handlebar 4 , a receptacle 13 for the pedal support 5 and a receptacle 14 for the driver's seat 6 . The handlebar 4, the pedal support 5 and the driver's seat 5 are only on the figure 1 shown in . A resiliently configurable rear structure 60 , shown in dashed lines, is fastened to the electric bicycle frame and serves to accommodate the (not shown) rear wheel of the electric bicycle. The two housing halves 2 , 3 consist of a fiber-reinforced thermoplastic containing semiaromatic polyamide. The joining together of the two housing halves 2 , 3 forms an inner cavity 7 which accommodates the battery 30 of the electric bicycle, the electric motor 40 and the pedal support 5 . The joining of the plastic housing halves 2 , 3 also enables the battery 30 , the e...

Abstract

The invention relates to a method for manufacturing pedelec frames with plastics. The invention relates to a method for manufacturing a plastic pedelec frame (1) by, preferably integrally, joining two matching plastic half-shells (2, 3), said pedelec frame (1) being provided with receptacles (12, 13, 14) for a handlebar (4), a bottom bracket (5) and preferably a seat (6). The two plastic half-shells (2, 3) are made from a fiber-reinforced thermoplastic material containing a partially aromatic polyamide, using an injection molding process. The invention also relates to a pedelec frame (1) manufactured by said method.

Description

technical field [0001] The invention relates to a method for producing an electric bicycle frame (Pedelec-Rahmen), in which two plastic housing halves are joined together and connected to one another, preferably in a materially bonded manner. An electric bicycle differs from a normal bicycle by having an additional electric motor, a battery element for the motor's drive and usually control electronics for the motor. In practice, e-bike frames are usually manufactured from aluminum. Background technique [0002] Compared with ordinary bicycles, electric bicycles are characterized in that they must additionally be equipped with an electric motor and at least one battery element. To support the e-bike drive, the electric motor can be switched on by the driver. Furthermore, electric bicycles usually contain control electronics which measure the applied force or speed and activate or switch off the motor when a certain value is reached. The additional elements of the electric ...
