Abstract
The invention provides an injection-molded bicycle frame by using a carbon-plastic material. The bicycle frame comprises a frame main body as well as a front fork, a seat stay, a left chain stay and a right chain stay which are integrally injected and molded by using the carbon-plastic material, wherein, the frame main body is composed of a left half frame and a right half frame which are respectively and integrally prepared from the carbon-plastic material in the injection molding mode. In the invention, the bicycle frame is produced by a new carbon-fiber injection molding process, wherein, the frame body is divided into the left and right parts which are respectively prepared in the injection molding mode, which belongs to original innovation of the manufacturing technology in the carbon-fiber bicycle industry, provides an effective and feasible process for large-scale and efficient production of carbon-fiber bicycles and realizes successful application of cladding and granulating and injection molding processes to production of the bicycle frame. The process has the advantages of accelerating popularization of the carbon-fiber bicycles in China with low fabrication cost so that the bicycles become popular commodities, promoting development of the carbon-fiber bicycle industry in China and providing rich experience for development of subsequent carbon-fiber products.
Description
Technical field
The present invention relates to a kind of carbon fiber bicycle, the cycle frame of particularly a kind of carbon moulding material injection mo(u)lding.
Background technology
It is main that existing manufacturing carbon fiber bicycle support is stuck with paste technology with hand mostly; This technology is compiled into cloth → resin prepreg stain → air-dry → cutting → roll → solidify → polish → application by carbon fiber wire; Operation is numerous and diverse, and production efficiency is extremely low, cost is high, and product can not be recycled.
Summary of the invention
The technical matters that the present invention will solve is the deficiency to prior art, has proposed the cycle frame of the carbon moulding material injection mo(u)lding that a kind of production efficiency is high, cost is low.
The technical matters that the present invention will solve realizes through following technical scheme; The cycle frame of a kind of carbon moulding material injection mo(u)lding; Be characterized in: the front fork, Seat stay, the left lower fork in back and bottom right, the back fork that comprise main body of vehicle frame and adopt the moulding of carbon moulding material integral molded plastic; Main body of vehicle frame comprises upper beam, a pipe, underbeam, seat pipe and central siphon bottom bracket assembly, and the two ends up and down of head pipe are provided with a pipe clamp circle, and the upper end of seat pipe is provided with a pipe clamp circle; Said main body of vehicle frame is combined by left semi-frame and right semi-frame; A left side semi-frame and right semi-frame be respectively by the moulding of carbon moulding material integral molded plastic, be provided with between left semi-frame and the right semi-frame fastening that cooperatively interacts along and captive joint through the binding bolt that is provided with at interval and to be integral, manage in before in the head pipe of main body of vehicle frame, being provided with; In the seat pipe of main body of vehicle frame, be provided with pipe in the back; The left lower fork in back, back bottom right fork are connected through colluding claw assembly respectively with between the Seat stay, be provided with the pipe fork between the seat pipe of Seat stay and main body of vehicle frame and be connected external member, the central siphon bottom bracket assembly be provided with after left lower fork, after the bottom right pitch the grafting angle that joins respectively.
The technical matters that the present invention will solve can also realize that further the central axis hole of central siphon bottom bracket assembly is provided with left and right inserts that left inserts and left semi-frame are injection molded into integral piece through following technical scheme, right inserts and right semi-frame are injection molded into integral piece.
The present invention compared with prior art; Adopting the carbon fiber injection molding process to produce cycle rack is a kind of new manufacturing process; Main body of vehicle frame branch left and right sides two parts injection mo(u)lding respectively belong to initiative; Be the once innovation of carbon fiber bicycle industry production technology,, high efficiency production extensive to carbon fiber bicycle provides a kind of effective, feasible technology, also is to coat granulation, the successful Application of Shooting Technique on cycle rack is produced.The application of this technology, the cost cost is low, with accelerating popularizing of China's carbon fiber bicycle, makes it to become staple commodities, promotes the development of domestic carbon fiber bicycle industry, for the exploitation of the follow-up goods of carbon fiber provides rich experience.
