Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to an integrated lightweight handlebar and bicycle. Background Technology

[0002] The drop handlebars allow riders to grip the handlebars in multiple different positions, facilitating changes in riding posture and aiding in long-distance riding. At the same time, the drop handlebars also cause the rider to lean forward, which can increase riding speed.

[0003] Currently, most road bike handlebars use round tubes. Ordinary round tube handlebars have a simple and strong structure, but they have a large frontal area. Also, if a cable-driven hydraulic converter is installed, it must be installed externally, which is not aesthetically pleasing and also increases wind resistance. Therefore, aerodynamic handlebars with a smaller frontal area and lower wind resistance are gradually gaining popularity. However, to ensure the structural stability of aerodynamic handlebars, it is usually necessary to increase the width in the frontal direction and the thickness of the tube wall to ensure structural stability, which further increases the weight. Moreover, ordinary aerodynamic handlebars cannot effectively conceal the installation of the cable-driven hydraulic converter, and the cable and hydraulic hose routing paths are inevitably exposed, creating safety hazards and further reducing aesthetics.

[0004] Therefore, we have proposed an integrated lightweight handlebar and bicycle. Utility Model Content

[0005] This application provides an integrated lightweight handlebar and bicycle to at least solve the problems of the prior art where ordinary round tube handlebars can only be assembled with exposed hydraulic converter pumps, which is not aesthetically pleasing and has greater wind resistance; and the heavy weight of aerodynamic handlebars makes it impossible to properly conceal the hydraulic converter pump, inevitably resulting in exposed cable and oil pipe routing paths, creating safety hazards and further degrading the appearance.

[0007] The main handle is integrally formed and includes at least a main body, a handlebar portion vertically disposed in the middle of one side of the main body, and two auxiliary handlebar connecting portions respectively formed at the two free ends of the main body. The lower end of the main body has an open cavity and an assembly cavity located in the middle of the open cavity and communicating with the handlebar portion.

[0008] There are two auxiliary handles, which are curved handles and are respectively fixed to the two auxiliary handle connection parts;

[0009] Two bottom covers are fitted together at the bottom of the open cavity and located on both sides of the assembly cavity.

[0010] The two bottom covers cooperate with the main body to form a flat, arc-shaped handle air-breaking surface.

[0011] Optionally, each of the two handle portions has a threading hole connected to the open cavity.

[0012] Optionally, the inner wall of the open cavity is integrally formed with a plurality of reinforcing protrusions in a honeycomb structure.

[0013] Optionally, the inner wall of the open cavity is further integrally formed with a plurality of reinforcing ribs radially arranged from the handle portion as the origin.

[0014] Optionally, the handle portion is provided with a handle hole connected to the assembly cavity.

[0015] Optionally, the outer wall surface of the auxiliary handle connecting portion is formed with a plurality of assembly steps, and the auxiliary handle is sleeved on the auxiliary handle connecting portion and is deformed by external force to be fixed on the auxiliary handle connecting portion.

[0016] Optionally, a wire pulling oil pressure up pump is installed in the assembly cavity, and the wire pulling oil pressure up pump has two wire driving ends respectively facing the two auxiliary handle connecting portions, and at least one oil outlet end facing the handle hole.

[0017] Optionally, a brake handle is further included, which is fixed on the auxiliary handle and connected with a pulling wire, and the other end of the pulling wire enters the open cavity along the threading hole and is connected with the wire driving end of the wire pulling oil pressure up pump.

[0018] In a second aspect, the application provides a bicycle, which includes a frame, and the frame has a handle tube, and the handle tube is provided with the integrated lightweight handle of the first aspect.

[0019] Compared with the related art, the integrated lightweight handle and the bicycle provided by the application have at least the following technical effects:

[0020] By forming the assembly cavity and the open cavity at the lower part of the main handle, the reinforcing protrusions in a honeycomb structure and the reinforcing ribs radially arranged are formed on the inner wall of the open cavity, the structural strength of the main handle is effectively strengthened, and finally the open cavity is closed by the bottom cover to form an internal hollow structure, which further reduces the weight of the handle, so that the lightweight handle with high structural strength and beautiful appearance is realized; and the pulling wire connected with the brake handle enters the open cavity along the threading hole and is connected with the wire driving end of the wire pulling oil pressure up pump, which realizes the hidden installation of the brake pulling wire, the oil pipe can also be hidden in the assembly cavity and extended into the handle hole, so that it directly enters the inside of the frame when the bicycle is assembled, realizes the hidden layout, and the pulling wire and the oil pipe are not exposed, which is more tidy and beautiful, and does not increase the resistance of the windward surface.
