Integrated middle pipe of electric bicycle and hydraulic forming method

Abstract

The invention relates to an integrated middle pipe of an electric bicycle and a hydraulic forming method. The middle pipe is connected with a charging seat pipe, the middle pipe and the charging seatpipe are machined and integrally formed through a hydraulic method, the charging seat pipe is integrally formed at the lower end of the middle pipe, and the middle pipe and the charging seat pipe arehollow; the charging seat pipe is at least provided with a flat side face used for forming a mounting part of a charging base, and the mounting part comprises a settling plate and an inserting interface; and the settling plate is formed by sinking towards the interior of the charging seat pipe of the middle part of the flat side face, the settling plate is provided with a mounting position for fixing the charging base, and the inserting interface is formed in the middle of the settling plate to allow the charging base to be exposed outside. The charging base and the middle pipe of the electricbicycle are integrally formed by adopting the method of hydraulic machining after improving is conducted, a charging base mounting structure is formed on the charging seat pipe, welding is not required, and manpower, material resources and the cost are reduced.

Description

technical field [0001] The invention relates to a middle tube structure of an electric bicycle. Background technique [0002] Usually the electric bicycle charging stand is set on the upper left side of the down tube or the lower side of the down tube. Because there are many holes in the down tube, the charging stand and other holes are easy to break, which is not conducive to the strength and appearance. Some existing electric bicycles will The installation structure of the charging stand is fixed on the middle tube by welding, which increases accessories and process steps, and also affects the appearance of the car body, so there is a need for improvement. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved middle tube of an electric bicycle and a corresponding processing method. [0004] The technical solution adopted by the present invention to solve the technical problem is: an integrated middle tub...
