Description

Technical Field

[0001] This utility model relates to the field of motorcycle handlebar technology, specifically to a reinforced handlebar. Background Technology

[0002] Motorcycles, as a flexible and convenient means of transportation, play an indispensable role in people's daily travel, sports and entertainment, and logistics. The handlebars, as the core component of the motorcycle's control system, are in direct contact with the rider's hands and bear the crucial task of controlling the motorcycle's direction and speed, as well as transmitting various operational commands. Their performance not only affects the comfort and convenience of riding but also plays a decisive role in the motorcycle's safety.

[0003] From an overall structural perspective, handlebars typically consist of a bend section and handlebars at both ends of the bend section. Most handlebars employ simple splicing or welding processes, with the bend section and handlebars directly mechanically joined using bolts, nuts, or other fasteners, or directly welded together. This design can, to a certain extent, meet the basic needs of daily motorcycle riding, ensuring the normal function of the handlebars under normal use and light load conditions. However, during high-speed riding, encountering bumpy roads or emergency braking, the spliced ​​joints may loosen due to the fasteners, easily causing relative displacement between components and affecting the handlebar's control precision. Furthermore, welded joints, under long-term alternating stress, are prone to welding fatigue cracks. As these cracks propagate, they may eventually lead to fracture, posing a significant safety hazard to the rider. Utility Model Content

[0004] The present invention aims to provide a reinforced handlebar to enhance the strength of the connection between the handlebar bend and the handlebar.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A reinforced bicycle handlebar includes a bend section and handlebars at both ends of the bend section. The bend section and handlebars are connected by a coaxial sleeve. The end of the bend section is provided with a mounting groove that mates with the outer surface of the sleeve. The end of the handlebar is mates with the inner surface of the sleeve. The bend section, sleeve, and handlebars are provided with coaxial pin holes that penetrate radially. The pins pass through the pin holes to axially fix the bend section, sleeve, and handlebars.

[0006] The principles and advantages of this scheme are: 1. Insert the sleeve into the mounting groove of the elbow section and insert the retaining block into the groove. Then insert the end of the handlebar into the sleeve and connect the internal spline with the external spline. Finally, drill the pin hole and insert the pin, then weld and grind. This distributed installation method is simple and easy to master. Welding the two ends of the pin to the pin hole further enhances the connection's strength. Grinding away the weld spatter not only makes the handlebar more aesthetically pleasing but also eliminates potential safety hazards such as scratches to the user.

[0007] 2. Drilling the pin hole after the elbow section, sleeve and handle are connected can ensure that the pin hole is machined in one go after the elbow section, sleeve and handle are completely aligned. This avoids the cumulative error caused by separate machining, ensures the coaxiality of the hole position, and allows the pin to be easily installed and achieve the best fixing effect.

[0008] 3. A sleeve was added. As an independent reinforcing component, the sleeve is used for transitional connection in the traditional rod-to-rod connection, which increases the cross-sectional area and moment of inertia at the connection. Furthermore, the elbow section, sleeve and handle are connected in sequence, which reduces the problem of easy breakage in rod-to-rod connections, avoids stress concentration at the connection, and fundamentally improves the structural strength of the connection.

[0009] 4. Using pins to connect the elbow section, sleeve, and handlebars simultaneously can effectively prevent the elbow section and handlebars from moving in the axial direction and rotating relative to each other in the circumferential direction. This avoids the loosening of components under huge tensile and compressive loads, and the reliability is far higher than that of designs that rely solely on friction connection. It ensures the firmness of the connection between the various components of the handlebar from multiple dimensions.

[0010] Preferably, as an improvement, the mounting groove and the sleeve are interference fit, and the sleeve and the handle are also interference fit.

[0011] Technical effects: The above-mentioned configuration in this solution utilizes the elastic deformation between components through interference fit, providing a large preload and static friction force for the entire connecting body. This reduces gaps caused by loose connections, lowers the possibility of stress concentration, improves the overall structural stability of the handlebars, and extends their service life.

[0012] Preferably, as an improvement, the depth of the mounting groove matches the length of the sleeve.

[0013] Technical benefits: The above-mentioned setup ensures that after assembly, the end of the sleeve is flush with the end of the handle, without creating an abrupt step, resulting in a smoother and more aesthetically pleasing product appearance. It also facilitates installation by workers, as the flush alignment of the sleeve end with the handle indicates proper installation, improving installation efficiency and accuracy and reducing potential errors and problems during the installation process.

[0014] Preferably, as an improvement, the bottom of the mounting groove is provided with an annular groove, and the end of the sleeve is provided with an annular locking block that engages with the groove.

[0015] Technical effect: The above-mentioned configuration provides additional axial fixing force compared to interference fit. During long-term use or when subjected to large external impact, the friction may decrease, but the mechanical fit between the block and the slot is not affected by the change in friction and can always maintain a stable axial fixing effect, which greatly enhances the reliability of the connection between the various components of the handlebar.

[0016] Preferably, as an improvement, the inner surface of the sleeve is provided with an internal spline, and the end of the handle is provided with an external spline that mates with the internal spline.

[0017] Technical benefits: With the above-mentioned configuration, the spline can withstand and transmit very large torque, avoiding internal relative rotation of the handlebars during use. Furthermore, the spline anti-rotation is a purely mechanical interlock, resulting in higher reliability and longer lifespan.

[0018] Preferably, as an improvement, the length of the pin is less than the diameter of the bend section.

[0019] Technical effect: The above-mentioned design ensures that the two ends of the pin do not protrude from the handle surface, preventing the protruding parts from scratching the user's clothing or skin. It also provides a foundation for subsequent welding and polishing, resulting in a smooth and seamless connection at the final product, with almost no visible connection marks, thus enhancing the product's aesthetics.

[0025] The following detailed description illustrates the specific implementation method: Example The basics are as follows: Figure 1-4 As shown: A reinforced bicycle handlebar 1 includes a bend section 11 and handlebar supports 12 disposed at both ends of the bend section 11. The bend section 11 and handlebar supports 12 are connected by a coaxially arranged sleeve 3. The bend section 11, sleeve 3, and handlebar supports 12 are coaxially arranged. The end of the bend section 11 is provided with a mounting groove 2 that fits with the outer surface of the sleeve 3. The mounting groove 2 and the sleeve 3 are interference-fitted. The end of the handlebar supports 12 is fitted with the inner surface of the sleeve 3. The sleeve 3 and the handlebar supports 12 are also interference-fitted. The bend section 11, sleeve 3, and handlebar are sequentially sleeved, that is, the sleeve 3 is sleeved on the end of the handlebar supports 12, and the end of the bend section 11 is then sleeved on the sleeve 3. The bend section 11, sleeve 3, and handlebar supports 12 are provided with coaxial pin holes 5 that penetrate radially. The pins 5 pass through the pin holes 5 to axially fix the bend section 11, sleeve 3, and handlebar supports 12, preventing the bend section 11 and handlebar supports 12 from moving circumferentially or rotating relative to each other.

[0026] The depth of the mounting groove 2 matches the length of the sleeve 3, that is, after the sleeve 3 is inserted into the mounting groove 2, it is flush with the end of the handle 12.

[0027] The bottom of the mounting groove 2 is provided with an annular groove 21, and the end of the sleeve 3 is provided with an annular locking block 32 that cooperates with and connects to the groove 21.

[0028] The inner surface of the sleeve 3 is provided with an internal spline 31, and the end of the handle 12 is provided with an external spline 4 that mates with and connects to the internal spline 31.

[0029] The length of pin 5 is less than the diameter of the bend section 11, and both ends of pin 5 are located inside pin 5 holes.

[0030] During actual installation, first insert the sleeve 3 into the mounting groove 2 of the elbow section 11, and also insert the retaining block 32 into the retaining groove 21. Then insert the end of the handle 12 into the sleeve 3, and connect the inner spline 31 with the outer spline 4. After the elbow section 11, sleeve 3 and handle 12 are connected, drill pin 5 holes radially at the connection point, ensuring that the pin 5 holes simultaneously penetrate the elbow section 11, sleeve 3 and handle 12. Then insert the pin 5, ensuring that both ends of the pin 5 are located within the pin 5 holes, i.e., not exceeding the outer surface of the elbow section 11. Then weld the two ends of the pin to the pin 5 holes. After welding, grind along the outer surface of the elbow section 11 to remove the weld scars. The installation is then complete.
