Description

Technical Field

[0001] This application relates to the field of bicycle technology, and in particular to a bicycle handlebar and a bicycle. Background Technology

[0002] As the core component connecting the bicycle fork and wheels, the handlebars play a dual crucial role in riding: they are both the primary support point for the rider's body and the central hub for controlling the vehicle's direction. While riding, riders can dynamically adjust the bicycle's balance in real time by slightly tilting the handlebars left or right, maintaining an upright riding posture, and confidently navigating bumpy roads, curves, and other complex terrains. This significantly reduces the risk of tipping over and dramatically improves the accuracy and safety of the riding trajectory. The structural design of the handlebars has a decisive impact on the riding experience, directly affecting comfort, handling responsiveness, and riding safety.

[0003] Currently, bicycle handlebar manufacturing generally employs an integrated welding process between the stem and handlebars. While this traditional connection method ensures initial structural strength, it has a significant drawback—it cannot achieve detachable separation of the stem and handlebars. If the handlebars are damaged due to collisions, wear, or other reasons, even if only the handlebars or stem are faulty, the entire handlebar assembly must be disassembled and replaced. This not only increases repair costs but also wastes spare parts, thus requiring improvement. Utility Model Content

[0004] To facilitate the replacement of handlebar components and reduce maintenance costs, this application provides a bicycle handlebar.

[0005] Firstly, the bicycle handlebar provided in this application adopts the following technical solution: A bicycle handlebar includes a stem, handlebars, and fasteners. The stem includes a fork tube connector and a cross tube connector connected to each other. The fork tube connector is used to connect to the bicycle fork tube. Slots are provided at both ends of the cross tube. Two handlebars are provided, and the two handlebars are respectively inserted into the two slots. The handlebars are locked to the cross tubes by the fasteners.

[0006] By adopting the above technical solution, the stem connects to the bicycle's fork tube, and the handlebars are used by the user to grip and control the bicycle's direction. When the stem or handlebars are damaged, the fasteners can be loosened first, and then the handlebars can be pulled out of the stem's slot to separate the stem and handlebars. The corresponding parts can then be replaced, and after replacement, the stem and handlebars can be re-secured together using the fasteners. This eliminates the need to replace the entire handlebars, reducing maintenance costs.

[0007] Preferably, the fastener is a fastening bolt or a fastening screw.

[0008] By adopting the above technical solution, the fastening bolts or screws are all detachable parts. The stem and handlebars are fixed by screwing, while ensuring that the stem and handlebars are detachable.

[0009] Preferably, the inner wall of the slot is provided with a plurality of first ridges, each of the first ridges being distributed in a ring; one end of the handlebar is provided with a plurality of second ridges, each of the second ridges being distributed in a ring, and the second ridges engaging between two adjacent first ridges.

[0010] By adopting the above technical solution, when connecting the handlebars and the crossbar, align the end of the handlebar with the first ridge, then gradually insert it into the slot, and finally lock it in place using fasteners. The first and second ridges cooperate with each other to increase the contact area between the handlebars and the crossbar, thereby improving the stability of the connection between the handlebars and the crossbar.

[0011] Preferably, the handlebar includes an integrally connected straight tube section and a curved tube section, the second ridge is provided on the straight tube section, and the straight tube section is connected to the horizontal tube section.

[0012] By adopting the above technical solution, both the straight section and the curved section can be used for the user's hands to support it, and the user can place their hands on the straight section or the curved section as needed.

[0013] Preferably, the fork tube connection portion has a shaft hole, a vertical opening, and a mounting hole. The shaft hole is for the fork tube to pass through, the vertical opening communicates with the shaft hole, and the mounting hole communicates with the vertical opening and is used for bolt connection.

[0014] By adopting the above technical solution, when it is necessary to install the handlebars, first pass the fork tube through the shaft hole on the fork tube connector, and then use a bolt to pass through the vertical opening and screw it into the mounting hole to fix the fork tube and the fork tube connector.

[0015] Preferably, the fork tube connection portion is further provided with a recessed groove, the recessed groove being close to the axle hole, and the recessed groove being used to engage with the bicycle frame.

[0016] By adopting the above technical solution, the groove can be snapped onto the bicycle frame, increasing the contact area between the fork tube connection and the bicycle, improving the stability of the handlebar installation, and making the connection between the handlebar and the front end more secure.

[0017] Preferably, the outer surfaces of the stem and handlebars are coated with a paint layer.

[0018] By adopting the above technical solutions, the paint layer includes, but is not limited to, amino paint, acrylic paint, and epoxy resin paint. On the one hand, the paint layer can provide a wide variety of colors and gloss levels, giving the handlebars different appearances, thereby meeting the aesthetic needs of different users and making the vehicle look more beautiful and stylish overall.

[0019] On the other hand, the paint layer can form a protective film on the surface of the handlebar, isolating the metal from the outside air and moisture, greatly slowing down the corrosion rate of the metal and extending the service life of the handlebar.

[0020] Secondly, this application also provides a bicycle with a handlebar comprising all the structures described above.

[0021] In summary, this application includes at least one of the following beneficial technical effects: (1) By separating the handlebars into a stem and a handlebar, when the stem or handlebar is damaged, the fasteners can be loosened first, and then the handlebar can be pulled out of the stem slot to separate the stem and handlebar. Then the corresponding parts can be replaced, and the stem and handlebar can be fixed together again using fasteners. In this way, it is not necessary to replace the entire handlebar, thus reducing maintenance costs.

[0022] (2) By setting the first convex groove and the second convex groove, the first convex groove and the second convex groove cooperate with each other to increase the contact area between the handlebar and the cross tube and improve the connection stability between the handlebar and the cross tube.

[0023] (3) By setting a paint layer, the paint layer can improve the aesthetics of the handlebar surface on the one hand, and protect the handlebar on the other hand, thus extending the service life of the handlebar. Attached Figure Description

[0029] In the description of the embodiments of this application, unless otherwise expressly specified and limited, the technical terms "installation," "connection," "joining," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection; a detachable connection; an integral part; or a mechanical connection. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0030] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Without conflict, those skilled in the art can combine and integrate the different embodiments or examples shown in this application, as well as the features of those embodiments or examples.

[0031] This application discloses a bicycle handlebar. (Refer to...) Figures 1 to 3The bicycle handlebars include a stem 1, a handlebar 2, and fasteners 3. The stem 1 and handlebar 2 are made of metal or carbon fiber. In some embodiments, the outer surfaces of both the stem 1 and handlebar 2 are coated with a paint layer (not shown in the figure). The paint layer uses existing conventional technology and may be, but is not limited to, polyurethane resin and epoxy resin. The paint layer is not only an aesthetic "outer garment" for the bicycle handlebars but also a crucial "protective shield" for ensuring vehicle performance. By tightly adhering to the surface of components such as the frame, it forms a physical barrier, isolating moisture, oxygen, and external pollutants, effectively preventing metal corrosion. Simultaneously, the hardness and elasticity of the paint film resist mechanical damage such as scratches and impacts during riding, extending the service life of components. Some special paint layers (such as fluorescent paint and reflective paint) can also improve visibility during nighttime riding, enhancing safety; while personalized coatings (such as gradient colors and brand logos) combine aesthetic value with brand recognition, making the bicycle more personalized and attractive in addition to its practicality.

[0032] The stem 1 includes an integrally connected fork tube connector 11 and cross tube 12. The fork tube connector 11 is used to connect to the bicycle fork tube, and the cross tube is used to connect to the handlebars 2. Both ends of the cross tube 12 have slots 4. In this embodiment, two handlebars 2 are provided, each inserted into one of the two slots 4. The handlebars 2 are locked to the cross tube 12 by fasteners 3. In this embodiment, the fasteners 3 are bolts or screws. The bolts or screws pass through the cross tube 12 and are locked to the handlebars 2, thereby completing the fixation of the handlebars 2 and the cross tube 12.

[0033] Specifically, the handlebar 2 includes an integrally connected straight tube section 21 and curved tube section 22. Both the straight tube section 21 and the curved tube section 22 can be used for the user's hands to support the handlebar. During riding, the user can place their hands on the straight tube section 21 or the curved tube section 22 as needed, thereby improving the riding experience and comfort. The inner wall of the slot 4 is provided with several first raised patterns 5, each first raised pattern 5 arranged in a ring shape. One end of the straight tube section 21 is provided with several second raised patterns 6, also arranged in a ring shape. The second raised patterns 6 engage between adjacent first raised patterns 5, realizing the connection between the straight tube section 21 and the cross tube section 12. The first raised patterns 5 and the second raised patterns 6 cooperate with each other to increase the contact area between the handlebar 2 and the cross tube, thereby improving the connection stability between the handlebar 2 and the cross tube.

[0034] In this embodiment, the fork tube connector 11 has a shaft hole 7, a vertical opening 8, and a mounting hole 9. The shaft hole 7 has a circular cross-section and is used for the fork tube to pass through. The vertical opening 8 and the shaft hole 7 are interconnected, and the mounting hole 9 is interconnected with the vertical opening 8. The mounting hole 9 is used for bolts to pass through and for screwing. When the handlebar needs to be installed, the fork tube is first passed through the shaft hole 7 on the fork tube connector 11, and then a bolt is passed through the vertical opening 8 and screwed onto the mounting hole 9 to fix the fork tube and the fork tube connector 11. There are two mounting holes 9, which are parallel to each other and distributed vertically. Multiple mounting holes 9 allow multiple bolts to pass through, further improving the firmness of the connection between the fork tube connector 11 and the fork tube.

[0035] In addition, the fork tube connector 11 is provided with a recess 10, which is close to the axle hole 7. The recess 10 is used to snap onto the bicycle frame. After the fork tube and the fork tube connector 11 are installed, the recess 10 is snapped onto the bicycle frame. The shape of the recess 10 matches the shape of the corresponding position on the bicycle frame. The presence of the recess 10 increases the contact area between the fork tube connector 11 and the bicycle, improves the stability of the handlebar installation, and makes the connection between the handlebar and the front end more secure.

[0036] The implementation principle of a bicycle handlebar according to an embodiment of this application is as follows: When the stem 1 or handlebar 2 is damaged, the connection between the fork tube and the fork tube connector 11 can be disconnected first. Then, the fastener 3 on the cross tube 12 is loosened, and then external force is applied to overcome friction to pull the handlebar 2 out of the slot 4 of the stem 1, thus separating the stem 1 and the handlebar 2. Finally, the corresponding parts are replaced, and after replacement, the stem 1 and handlebar 2 are fixed together again using the fastener 3 (fastening bolts or fastening screws). In this way, it is not necessary to replace the entire handlebar, realizing the individual replacement of bicycle parts and reducing maintenance costs.

[0037] Based on the above embodiments, this application also provides a bicycle, which includes a bicycle handlebar with all the above-described structures. Since the structure of the handlebar has been discussed in detail above, it will not be repeated here.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
