Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber bicycles, in particular to a carbon fiber bicycle handlebar. Background Art
[0002] As a new type of material, carbon fiber is widely welcomed by people because of its light weight and high strength. It is very common to use carbon fiber materials in products such as bicycle frames and bicycle handlebars.
[0003] The following is a brief introduction to the method for making carbon fiber products (for details, please refer to the patent document with application number: 2021109783153, entitled "A method for making carbon fiber products"), which mainly includes the following steps: S1, making a skeleton core material: making an EPS core material that is compatible with the appearance structure, shape, and size of the product, and putting a nylon air bag on the outside of the EPS core material along the extension direction of the EPS core material;
[0004] S2, rolling and forming: stacking and rolling the carbon fiber cloth on the nylon air bag of the EPS core material in step S1 according to the structure, shape and size of the product, so that the product is initially formed;
[0005] S3, hot forming: the product preliminarily formed in step S2 is placed in the lower mold of the prepared matching forming mold, the air pipe is connected to the nylon air bag, and the nylon air bag is inflated through the air pipe. After the inflation is completed, the shape is fixed, and then the upper mold of the forming mold is buckled on the lower mold, and then the buckled forming mold is placed in the forming furnace to heat and pressurize to form the product;
[0006] S4, dissolving the EPS core material: pouring dichloromethane solvent into the nylon air bag of the product formed in step S3, so that the dichloromethane solvent dissolves the EPS core material in the nylon air bag.
[0007] According to the above-described production method, the obtained carbon fiber product (such as a carbon fiber bicycle handlebar) will have channels inside due to the dissolution of the EPS core material, and since the wall thickness of the carbon fiber is generally small, the remaining channels are generally relatively wide.
[0008] At present, carbon fiber bicycle handlebars usually use these wide channels to hide the brake lines, gear lines and other pipelines. Although on the surface the wide channels can allow the brake lines, gear lines and other pipelines to have a larger activity space, thereby reducing the friction or wear between the pipelines, but there is a problem that is not conducive to production: that is, because the channel is too large, and the threading openings of multiple required outlets have different directions and the threading routes are uncertain, the threading process of the brake lines, gear lines and other pipelines is very inconvenient and easy to make threading errors, resulting in low threading efficiency and reduced production efficiency. Utility Model Content
[0009] The utility model aims to provide a carbon fiber bicycle handlebar to solve the technical problem that the carbon fiber bicycle handlebar in the prior art has a too large channel, and the threading opening directions of multiple required wires are different and the threading routes are uncertain, which makes the threading process of brake wires, gearshift wires and other pipelines very inconvenient and easy to make threading errors, thus resulting in low threading efficiency and reduced production efficiency.

[0011] Furthermore, a curved channel is provided inside the carbon fiber curved handle, and the curved channel is communicated with the main channel.
[0012] Furthermore, the carbon fiber handlebar body, the carbon fiber connector, and the carbon fiber curved handle are integrally formed and connected.
[0013] Furthermore, the curved channel is a curved channel with a circular cross section.
[0014] Furthermore, the upper end of the carbon fiber curved handle is bent and extended toward the upper rear and is connected to the carbon fiber handlebar body, and the lower end of the carbon fiber curved handle is bent and extended toward the lower rear.
[0015] Furthermore, the width of the carbon fiber handlebar body gradually decreases from the middle to the left and right ends.
[0016] Further, the first threading opening is arranged on the lower side wall between the carbon fiber handlebar body and the carbon fiber curved handle, and the opening of the first threading opening faces the carbon fiber curved handle.
[0017] Furthermore, the bottom wall of the middle part of the carbon fiber handlebar body and the bottom wall of the connecting channel are both provided with openings, and the two openings are distributed front and back.
[0018] Furthermore, the rear end of the carbon fiber connector is provided with an axial hole extending in the vertical direction, the second threading opening is located in the front lower part of the axial hole, and the rear side wall of the axial hole is provided with a vertical opening extending in the vertical direction.
[0019] Furthermore, the left side wall of the vertical opening is provided with a plurality of first screw holes distributed up and down, the right side wall of the vertical opening is provided with a vertical hole extending vertically, and the left side wall of the vertical hole is provided with a plurality of second screw holes distributed up and down, and the plurality of first screw holes can be respectively locked with the plurality of second screw holes by screws; the bottom surfaces on the left and right sides of the second threading opening are respectively provided with circular holes.
[0020] In summary, the technical solution of the utility model has the following beneficial effects: the structure design of the utility model is reasonable, (1) by including a carbon fiber handlebar body, the length of the carbon fiber handlebar body extends left and right, the middle part of the carbon fiber handlebar body is provided with a carbon fiber connector extending backward, and the left and right ends of the carbon fiber handlebar body are respectively provided with carbon fiber curved handlebars; so that the carbon fiber connector can be assembled and connected with the head pipe of the carbon fiber bicycle backward, and people can hold the carbon fiber curved handlebars at the left and right ends for control. (2) by providing a main channel inside the carbon fiber handlebar body, and providing a connecting channel inside the carbon fiber connector, the main channel is connected with the connecting channel; so that the wall thickness of the carbon fiber handlebar body and the carbon fiber connector can still be kept small, and the remaining channel can still be kept relatively wide.

(4) The side wall of the carbon fiber wire conduit is integrally formed and connected with the side wall of the main channel and the side wall of the connecting channel; thereby, the carbon fiber wire conduit can be manufactured and formed together with the carbon fiber handlebar body and the carbon fiber connector, thereby improving the strength of the connection. From this analysis, it can be seen that the utility model uses an internally embedded carbon tube (i.e., two carbon fiber wire tubes passing through the main channel and connecting the inside of the channel) so that the brake line, gearshift line and other lines can be quickly and accurately threaded along the carbon fiber wire tube with a moderate width and a straight and smooth inner tube, thereby greatly improving the threading efficiency and production efficiency. At the same time, because the internally embedded wire tube can fit closely with the subsequent brake line and gearshift line, it effectively reduces or even avoids the abnormal noise caused by the traditional brake line, gearshift line and the inner wall of the handlebar, solves the quality concerns and worries of users caused by abnormal noise, and thus improves the competitiveness of the product.
