Description

Technical Field

[0001] This invention relates to the field of bicycle handlebars, and more particularly to an integrated handlebar with internal cable routing. Background Technology

[0002] Handlebars, as an important control component of two-wheeled vehicles such as bicycles, e-bikes, and e-scooters, typically require accessories such as brake levers, throttles, and display / control switches, and are connected to the braking mechanism via brake cables (including mechanical cables or hydraulic hoses). In existing products, the common handlebar structure is a separate combination of horizontal handlebars and vertical stem. The brake lever is usually clamped to the outside of the horizontal handlebars using a clamp, and the brake cable is usually led out from the brake lever and then runs along the outside of the handlebars or the frame, and is then secured with cable ties or clips.

[0003] While the aforementioned external wiring solution is intuitive to install, it still has several shortcomings in actual use: First, the brake cable is exposed and easily pulled, scratched, or squeezed by external forces, leading to wear on the outer sheath, damage to the wire core, or oil pipe bending and leakage, affecting braking reliability and service life; Second, external wiring often requires multiple fixing points, resulting in more assembly steps, and the exposed wiring harness will disrupt the overall integrity and simplicity of the vehicle's appearance, which does not conform to the current trend of "internal wiring and concealed design" in vehicles; Third, the connection between the brake lever and the wiring is usually a stress-concentrated area, and the exposed connector is more susceptible to impact, causing loosening, leakage, or connector damage, resulting in higher maintenance costs in the later stages.

[0004] To improve appearance and protect wiring harnesses, some products attempt to introduce wiring harnesses into the handlebars or seat tubes. However, since handlebars and seat tubes are mostly separate structures, the wiring hole positions need to be precisely matched with the accessory installation positions. At the same time, the structural rigidity and coaxiality / angle consistency of the joints are greatly affected by processing and assembly, and the assembly precision requirements are high. Once the positioning is off, problems such as uneven wiring, interference and wear between the wiring harness and the hole wall, or instability of the brake lever mounting surface may occur.

[0005] Therefore, it is necessary to provide a new integrated handlebar with internal cable routing to solve the above-mentioned technical problems. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention provides an integrated handlebar with internal cable routing, which solves the problem that since the handlebar and the seat tube are mostly separate structures, the cable routing hole positions need to be precisely matched with the accessory installation positions. Once the positioning is deviated, problems such as uneven cable routing, interference and wear between the cable harness and the hole wall, or unstable brake lever mounting surface will occur.

[0007] The integrated handlebar with internal cable routing provided by the present invention includes a horizontal handlebar and a vertical handlebar, which are arranged in a T-shape. Two pairs of semi-ring plates are symmetrically arranged on the horizontal handlebar, and each pair of semi-ring plates is detachably connected by high-strength bolts. A protective plate is fixed to the bottom of the semi-ring plate, and the protective plate has threaded holes for fixing the brake lever with bolts. A cable pass-through hole is opened on the horizontal handlebar near the protective plate, and the brake cable passes through the cable pass-through hole from inside the horizontal handlebar and connects to the brake lever. The vertical handlebars consist of an integrally formed inclined portion and a vertical portion, with an obtuse angle between them. Both the horizontal handlebars and the vertical handlebars are hollow inside and interconnected.

[0008] In a preferred embodiment, a first adjusting pipe is connected to the bottom of the upright portion, and a second adjusting pipe is provided on one side of the first adjusting pipe; The first adjusting tube has sliders fixed on both sides, and the second adjusting tube has a groove on its inner wall, with the sliders slidably connected to the groove.

[0009] In a preferred embodiment, fastening screws are provided on both sides of the second adjusting tube. The fastening screws are inserted into the second adjusting tube and extend to the surface of the first adjusting tube. By applying a pre-tightening force to the fastening screws, the first adjusting tube and the second adjusting tube can be fixed together.

[0010] In a preferred embodiment, both the first adjustment tube and the second adjustment tube are hollow structures and communicate with the hollow cavity of the vertical handlebar, so that the brake cable can be threaded through the vertical handlebar and the first / second adjustment tube.

[0011] In a preferred embodiment, a wear-resistant sheath or a rounded transition structure is provided at the opening of the threading hole to reduce friction and wear between the brake cable and the wall of the threading hole.

[0012] In a preferred embodiment, the guard plate forms an outwardly extending protective edge or shield at the location where the brake lever and brake cable connect, to provide collision protection and protection against direct splashing of mud and water to the brake lever and cable connection.

[0013] The beneficial effects of this invention are: 1. The brake cable runs through the inside of the horizontal handlebar and connects to the brake lever through a cable hole, so that the main cable segment is hidden in the hollow cavity of the handlebar / stem tube, reducing the exposed length and the risk of damage from external forces such as scratches and pulls, thereby extending the service life of the cable harness.

[0014] 2. The vertical handlebars consist of an integrally molded inclined section and a vertical section, reducing the accumulation of assembly errors caused by split splicing and multi-segment connections, making the overall rigidity and fatigue resistance more stable, while reducing the accuracy requirements for installation alignment and angle calibration.

[0015] 3. The semi-ring plate and high-strength bolts enable detachable clamping, and the threaded holes on the guard plate allow the bolts to fix the brake lever. This ensures clamping strength while improving assembly efficiency and facilitating later disassembly and maintenance.

[0016] 4. Easy height / position adjustment and reliable locking: The bottom of the upright part is equipped with a first adjustment tube and a second adjustment tube. The slider and the guide groove cooperate and are locked with the fastening screw. The position can be adjusted within a certain range and relative rotation or loosening can be prevented, improving riding adaptability and usage stability. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 ,in Figure 1 A perspective view of the main structure of the integrated handlebar with internal cable routing provided by the present invention; Figure 2 for Figure 1 A magnified structural diagram of A is shown below; Figure 3 for Figure 1 A schematic diagram of the enlarged structure of B shown; Figure 4 A plan view of the main structure of the integrated handlebar with internal cable routing provided by the present invention; Figure 5 This is a schematic diagram of the fastening screw provided by the present invention.

[0021] In the specific implementation process, such as Figures 1-5 As shown, the present invention provides an integrated handlebar with internal cable routing, comprising a horizontal handlebar 1 and a vertical handlebar 2, which are arranged in a T-shape. Both the horizontal handlebar 1 and the vertical handlebar 2 are hollow and interconnected, forming an internal cable routing channel for arranging brake cables. The vertical handlebar 2 includes an integrally formed inclined portion 8 and a vertical portion 9, with an obtuse angle between the inclined portion 8 and the vertical portion 9 to meet the requirements of vehicle handling posture and structural transition strength. In a preferred embodiment, the horizontal handlebar 1 and the vertical handlebar 2 can be formed by bending / welding or forging metal tubing (such as aluminum alloy) and then machining, or they can be integrally cast or molded from carbon fiber composite materials to achieve a balance between weight, strength, and cost.

[0022] like Figure 1 As shown, two pairs of semi-ring plates 3 are symmetrically arranged on the horizontal handlebar 1. Each pair of semi-ring plates 3 is detachably connected by high-strength bolts 4, so that when each pair of semi-ring plates 3 is closed, it forms a clamping structure for the horizontal handlebar 1. A guard plate 5 is fixedly installed at the bottom of the semi-ring plate 3. The guard plate 5 has threaded holes 6. The brake lever can be securely installed by the bolts engaging with the threaded holes 6, making the brake lever installation position easier to position and the overall structure more compact. To achieve internal cable routing, a cable hole 7 is opened on the horizontal handlebar 1 near the guard plate 5. The brake cable is guided along the internal channel of the horizontal handlebar 1 to the cable hole 7 and then led out from the cable hole 7 to connect with the brake lever, thus hiding most of the brake cable segment inside the handlebar, reducing exposed wear and external damage.

[0023] In a preferred embodiment, the opening of the cable hole 7 can be provided with a rounded transition or a wear-resistant sleeve (such as a rubber ring / nylon bushing) to reduce the wear caused by the brake cable rubbing against the hole wall under long-term vibration; the guard plate 5 can form a partial shield at the connection between the brake lever and the cable routing, reducing the probability of foreign objects directly impacting the connector, and further protecting the brake lever and the cable routing connection.

[0024] like Figure 1-5As shown, a first adjusting tube 10 is connected to the bottom of the upright section 9, and a second adjusting tube 11 is provided on one side of the first adjusting tube 10. Slider blocks 12 are fixed to both sides of the first adjusting tube 10. A groove 13 matching the slider 12 is formed on the inner wall of the second adjusting tube 11. The slider 12 and the groove 13 are slidably connected, thus providing guidance and limiting during adjustment, and restricting the relative rotation between the first adjusting tube 10 and the second adjusting tube 11. Fastening screws 14 are provided on both sides of the second adjusting tube 11. The fastening screws 14 are inserted into the second adjusting tube 11 and extend to the surface of the first adjusting tube 10. By applying a pre-tightening force to the fastening screws 14, the first adjusting tube 10 and the second adjusting tube 11 are reliably fixed together. In a preferred embodiment, the first adjusting tube 10 and the second adjusting tube 11 can also be configured as a hollow structure and communicate with the interior of the vertical handlebar 2, allowing the brake cable to continue to be arranged concealed in the vertical direction and connected to the frame or braking mechanism (it can be led out from the bottom of the head tube depending on the overall vehicle structure), further reducing the exposed length and improving the appearance consistency.

Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
