Description

Technical Field

[0001] This utility model relates to the field of bicycle manufacturing, and in particular to a segmented 3D printed carbon fiber and titanium alloy combined road bike aero handlebar. Background Technology

[0002] Since its inception, the bicycle has been a popular and convenient mode of transportation. In recent years, with the growing popularity of low-carbon and environmentally friendly lifestyles, bicycles have become an indispensable part of almost every household. Especially with the support and promotion of high-end enthusiasts, titanium alloy bicycles have become a rising star in the domestic bicycle industry. As a high-end product in the bicycle industry, titanium alloy bicycles have consistently maintained high popularity. However, consumers are no longer just looking for bicycle frames; their demand for titanium alloy bicycle handlebars is also increasing.

[0003] While titanium alloy bicycles and accessories are highly sought after, manufacturing titanium alloy bicycle frames and accessories is not as simple as that of bicycle frames made with traditional materials. This is because titanium alloy has high hardness, and current processing technology struggles to create lightweight and aesthetically pleasing hollow structures while maintaining component strength. However, in the high-end bicycle market, especially for titanium alloy drop handlebars, consumers have a strong desire for a more aesthetically pleasing, integrated, and easier-to-manufacture titanium alloy drop handlebar. 3D printing can perfectly break down the current manufacturing barriers in the titanium alloy bicycle industry. Therefore, a segmented 3D-printed road bike aerodynamic drop handlebar combining carbon fiber and titanium alloy has emerged, characterized by its cross-material, cross-industry, and innovative nature. Utility Model Content

[0004] The purpose of this invention is to provide a segmented 3D-printed carbon fiber and titanium alloy combined pneumatic handlebar for road bikes, in order to solve the problems mentioned in the background art.

The titanium alloy pneumatic handlebar center connector has integrally formed reinforcing connectors on both sides. The left side of the titanium alloy pneumatic handlebar center connector is connected to the carbon fiber pneumatic left bend connector via the reinforcing connector, and the right side of the titanium alloy pneumatic handlebar center connector is connected to the carbon fiber pneumatic right bend connector via the reinforcing connector. A cable channel is provided at the center of the rear end of the titanium alloy pneumatic handlebar center connector, through which the brake cable can be threaded into the titanium alloy pneumatic handlebar center connector and the carbon fiber pneumatic bend connectors on both sides, and connected to the handlebar brake.

[0006] Preferably, the plug-in reinforcing joint has a 10mm butt-joint reinforcing joint, which allows the carbon fiber pneumatic left bend pipe joint and the carbon fiber pneumatic right bend pipe joint on both sides to be inserted into the plug-in reinforcing joint and bonded to the joint, and the bonding edges are ground after bonding.

[0007] Preferably, the titanium alloy pneumatic handle center connector, carbon fiber pneumatic left bend connector, and carbon fiber pneumatic right bend connector all adopt a flat shape to achieve a pneumatic effect, while maintaining a thin wall thickness, low weight, and improved aesthetics without affecting strength.

[0008] The beneficial effects of this utility model are: This utility model is reasonably designed, fills the gap in the field of carbon fiber and titanium alloy pneumatic handlebars, and can replace the bending process and bonding positioning fixtures in the traditional titanium alloy handlebar manufacturing process, and replace the overall mold forming in the traditional carbon fiber handlebar manufacturing process, greatly reducing the difficulty of manufacturing and processing.

[0011] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-3As shown, a segmented 3D-printed road bike pneumatic handlebar combining carbon fiber and titanium alloy includes a titanium alloy pneumatic handlebar center connector 1, a plug-in reinforcing connector 2, a carbon fiber pneumatic left bend tube connector 3, a carbon fiber pneumatic right bend tube connector 4, and a cable groove 5. The titanium alloy pneumatic handlebar center connector 1 has plug-in reinforcing connectors 2 integrally formed on both its left and right sides. The left side of the titanium alloy pneumatic handlebar center connector 1 is connected to the carbon fiber pneumatic left bend tube connector 3 via the plug-in reinforcing connector 2, and the right side of the titanium alloy pneumatic handlebar center connector 1 is connected to the carbon fiber pneumatic right bend tube connector 4 via the plug-in reinforcing connector 2. A cable groove 5 is provided at the center of the rear end of the titanium alloy pneumatic handlebar center connector 1, through which the brake cable can be threaded into the titanium alloy pneumatic handlebar center connector 1 and the carbon fiber pneumatic bend tube connectors on both sides, and connected to the handlebar brake. The plug-in reinforcing connector 3 has a 10mm butt-joint reinforcement connector, which allows the carbon fiber pneumatic left-hand bend connector 3 and carbon fiber pneumatic right-hand bend connector 4 on both sides to be inserted into the plug-in reinforcing connector 2 and bonded to the connector.
