Description

Technical Field

[0001] This application relates to the field of bicycle technology, and in particular to a racing bicycle front end crossing structure. Background Technology

[0002] Racing bicycles typically have braking and shifting systems. Braking systems are usually driven by steel cables encased in tubing that runs through the front and rear of the bicycle; or they can be driven by hydraulic fluid, which is transmitted through hoses running through the front and rear of the bicycle. Shifting systems are usually driven by steel cables encased in tubing that runs through the front and rear of the bicycle; or they can be driven by electrical signals, which are transmitted through wires running through the bicycle.

[0003] In order to achieve lower wind resistance and a cleaner appearance, modern racing bicycles typically design the braking system and gear system cables or wires to be completely hidden inside the handlebars and frame.

[0004] However, when athletes travel to competitions, they need to load their bicycles into special transport cases for transport. These cases often require the handlebar system to be disassembled and folded and secured to the frame for storage. In this case, the cable routing system's conduit can significantly hinder the disassembly and folding of the handlebars, and may even prevent proper storage within the transport case. Therefore, further improvements are warranted. Utility Model Content

[0005] To facilitate athletes in folding and storing their bicycles by removing the handlebars when taking them out, this application provides a racing bicycle handlebar crossing structure.

[0006] The technical solution for the racing bicycle front end crossing structure provided in this application is as follows:

[0007] A cable guide structure for a racing bicycle includes a cable guide seat installed between the handlebar stem and the head tube of the frame. The cable guide seat is sleeved on the fork tube, and its top is detachably connected to the bottom of the handlebar stem. A cable outlet is provided at the bottom of the handlebar, and the cable outlet is located on the front side of the handlebar stem. A cable inlet is formed inside the cable guide seat and is connected to the inside of the head tube. A cover plate is formed at the front end of the cable guide seat, extending to the cable outlet. The cover plate seals the cable outlet, and a cable routing cavity is formed between the cover plate and the handlebar, extending from the cable outlet to the cable inlet.

[0008] By adopting the above technical solution, the cable routing of the bicycle is as follows: the cable inside the handlebars is led out from the cable exit point, then laid along the cable routing cavity formed between the cover plate and the handlebars to the cable guide, and finally introduced into the head tube through the cable inlet inside the cable guide for internal routing. At this time, because the position of the cable exit point in the handlebars is moved forward to the front side of the handlebar stem, sufficient cable length can be reserved between the cable exit point in the handlebars and the cable inlet in the cable guide. This allows athletes to easily remove the handlebars for folding and storage when carrying the bicycle for competitions. Furthermore, in actual use, the cover plate can conceal this part of the cable routing, improving the overall aesthetics of the bicycle and reducing the wind resistance caused by exposed cables.

[0009] Optionally, the bottom of the handlebar is formed with a concave cable routing groove, and the cable routing groove extends from the cable outlet to the cable inlet; the cover plate is fitted to seal the cable routing groove to form a cable routing cavity, and the cover plate and the handlebar are smoothly transitioned.

[0010] By adopting the above technical solution, the cable routing channel is placed inside the handlebar, and the cover plate and handlebar are designed to have a smooth transition between them. This not only makes the cable routing structure between the cable outlet and the cable inlet as small as possible, but also effectively reduces the wind resistance coefficient at this location.

[0011] Optionally, a retaining post is formed inside the cover plate portion, and when the cover plate portion is sealed to the wiring groove, the retaining post is fastened to the inner wall of the wiring groove.

[0012] By adopting the above technical solution, after the cover plate is sealed in the cable tray, the locking post is fastened to the inner wall of the cable tray to achieve a locking seal of the cover plate, which facilitates the assembly or disassembly of the cover plate and the handlebar.

[0013] Optionally, the inner walls of the cable tray are inwardly tapering arc surfaces, and the locking posts are arranged on the left and right sides of the cover plate, with the locking posts on both sides forming an inward V-shape.

[0014] By adopting the above technical solution, during the handlebar installation process, as the handlebar is inserted, the cover plate gradually seals the cable routing groove. During this process, the inward-pointing locking posts on both sides smoothly engage with the inner wall of the cable routing groove, ensuring the cover plate is stably sealed within it. Furthermore, this inward-pointing locking post design facilitates assembly and disassembly for athletes.

[0015] Optionally, the top of the cable guide is countersunk, and the bottom of the handlebar stem is pluggably inserted into the top of the cable guide.

[0016] By adopting the above technical solution, a plug-in connection between the handlebar stem and the cable guide can be achieved, which facilitates subsequent disassembly or assembly.

[0017] Optionally, the cover plate portion and the inlet port have an arc-shaped transition.

[0018] By adopting the above technical solution, the area between the cover plate and the inlet is designed to have an arc-shaped transition, which facilitates the routing of cables inside the cable cavity and prevents the cables from being scratched and worn during use.

[0019] Optionally, the bottom of the cover plate and the wire guide seat have an arc transition shape.

[0020] By adopting the above technical solution, the bottom of the cover plate and the cable guide are designed to have a rounded transition to form a streamlined shape, which not only improves the overall aesthetics but also reduces wind resistance during riding.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The cable exit point in the handlebars has been moved forward to the front of the handlebar stem, allowing sufficient cable length between the exit point and the cable inlet in the cable guide. This allows riders to easily fold and store the bicycle by using this pre-existing cable routing when traveling for competitions. Furthermore, the cover plate can conceal this cable routing during actual use, improving the overall aesthetics of the bicycle and reducing wind resistance caused by exposed cables.

[0023] 2. The cable routing channel is placed inside the handlebar, and the cover plate and handlebar are designed to have a smooth transition between them. This can effectively minimize the cable routing structure between the cable outlet and the cable inlet, and also effectively reduce the wind resistance coefficient at this location.

[0024] 3. During handlebar installation, as the handlebars are inserted, the cover plate gradually seals the cable routing groove. During this process, the inward-pointing locking posts on both sides smoothly engage with the inner wall of the cable routing groove, securing the cover plate firmly in place. This inward-pointing locking post design also facilitates assembly and disassembly for the athlete. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a racing bicycle front end crossing structure.

[0034] Reference Figure 1 and Figure 2 A cable guide structure for a racing bicycle includes a cable guide 5 installed between the handlebar stem 2 in the handlebar 1 and the head tube 4 in the frame 3. The cable guide 5 is sleeved on the fork tube 6, and the bottom of the handlebar stem 2 is pluggably connected to the top of the cable guide 5.

[0035] Reference Figures 3-5 The bottom of the handlebar 1 has a cable outlet 7, which is located on the front side of the handlebar stem 2. The forward distance of the cable outlet 7 can be designed according to the installation depth of the handlebar stem 2 in the handlebar 1. Correspondingly, the cable guide 5 has a cable inlet 8 formed inside. The cable inlet 8 is located on the side close to the cable outlet 7 and is connected to the inside of the head tube 4, so that the cable in the handlebar 1 can be led out through the cable outlet 7, and then laid along the cable routing cavity formed between the cover plate 9 and the handlebar 1 into the cable guide 5. Finally, it is introduced into the head tube 4 through the cable inlet 8 in the cable guide 5 for internal cable routing.

[0036] Reference Figures 3-5 In this embodiment, the bottom of the handlebar 1 is formed with a concave cable routing groove 10, which extends from the cable outlet 7 to the cable inlet 8. Correspondingly, the front end of the cable holder 5 is formed with an upwardly curved duckbill-shaped cover plate 9, which extends to the cable outlet 7 and fits to seal the cable routing groove 10 to form a cable routing cavity. The cover plate 9 is used to hide this part of the cable, which not only improves the overall aesthetics of the vehicle body, but also reduces the wind resistance caused by exposed cables.

[0037] Reference Figures 3-5Specifically, in this embodiment, the top of the cable guide 5 is countersunk, and the bottom of the handlebar stem 2 can be plugged into the top of the cable guide 5. The left and right inner walls of the cable tray 10 are inwardly tapering arc surfaces. Correspondingly, the cover plate 9 has locking posts 11 formed inside. The locking posts 11 are arranged on the left and right sides of the cover plate 9, and the locking posts 11 on both sides are inwardly shaped. When the cover plate 9 is sealed on the cable tray 10, the locking posts 11 on both sides are respectively fastened to the inner walls of the cable tray 10, so as to fasten the cover plate 9 to the cable tray 10 of the handlebar 1.

[0038] Reference Figures 3-5 In this embodiment, the cover plate 9 and the handlebar 1 have a smooth transition, which effectively minimizes the cable routing structure between the cable outlet 7 and the cable inlet 8, while also effectively reducing the wind resistance coefficient at this location. The arc-shaped transition between the cover plate 9 and the cable inlet 8 facilitates cable routing within the cable cavity and prevents cable abrasion during use. The bottom of the cover plate 9 and the cable guide 5 have a rounded transition to form a streamlined shape, which improves the overall aesthetics and reduces wind resistance during riding.

[0039] The implementation principle is as follows: the cable outlet 7 in the handlebar 1 is moved forward to the front of the handlebar stem 2, so that a sufficient length of cable can be reserved between the cable outlet 7 in the handlebar 1 and the cable inlet 8 in the cable guide 5. This allows athletes to easily remove the handlebar 1 for folding and storage when carrying the bicycle for competitions. Simultaneously, in actual use, the cover plate 9 can conceal this part of the cable routing, improving the overall aesthetics of the bicycle and reducing the wind resistance caused by exposed cables.

[0040] 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.
