Description

Technical Field

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

[0002] Motorcycle brake levers are crucial control components on motorcycles, used to control the vehicle's braking system. Current motorcycle brake lever designs typically incorporate an adjustment mechanism between the brake lever and the grip to accommodate different riders' needs. For example, a toggle cap on top of the brake lever allows adjustment of the distance between the brake lever and the grip. While this design addresses the inconvenience for riders with different hand sizes to some extent, it still has significant shortcomings.

[0003] In practical use, due to the exposed surface of the handlebar knob and the lack of an effective locking design, it is easily displaced by accidental touches from the rider's fingers or vibrations from bumpy roads, thus changing the distance between the brake lever and the grip. This unintentional adjustment can interfere with the rider's operation, affecting driving stability and safety. Furthermore, existing adjustment mechanisms often lack intuitive prompts when indicating the adjustment angle, requiring riders to try multiple times to find the appropriate position, increasing the complexity of adjustment. Therefore, this paper researches and improves upon existing problems, providing a span-adjustable motorcycle handlebar to solve current issues, aiming to address both the problem and enhance practicality. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art or related technologies.

[0005] This utility model relates to an adjustable span motorcycle brake lever, specifically designed to solve the adjustment error problem caused by accidental touch or vibration in existing brake lever adjustments, and to improve the convenience and stability of the adjustment process. This utility model significantly enhances the accuracy and safety of motorcycle brake lever adjustment by improving the design of the torsion cap adjustment structure and limiting components.

[0006] This utility model includes a brake lever and a torsion cap adjustment structure for adjusting the distance between the brake lever and the grip, specifically including the following technical features: Locking function design: The top of the brake lever is provided with a torsion cap, the top of which is fixedly connected to the brake lever via a fixing component. The fixing component includes a boss, positioning holes, and a positioning rod. The boss is fixedly connected to the top of the brake lever, and multiple positioning holes are evenly distributed on its top. The positioning rod passes through the second through hole on the top of the torsion cap, with its bottom end inserted into the positioning hole. The movement direction of the positioning rod is controlled by a limiting component. When the brake lever is adjusted to the desired position, the positioning rod locks in the corresponding positioning hole, fixing the position of the torsion cap and preventing the position of the torsion cap from shifting due to accidental contact or vibration.

[0007] Intuitive adjustment marking design: The top of the boss is equipped with a label indicating the rotation angle of the toggle cap. The label corresponds one-to-one with the positioning hole, so that the driver can intuitively identify each adjustment position when adjusting, and can accurately adjust to the desired position without repeated attempts.

[0008] Elastic locking mechanism design: The limiting part includes a fixed frame, a pushing block, and an elastic block. The fixed frame is located at the top of the torsion cap and has a first through hole. The pushing block and the positioning rod are inserted into the first through hole. The elastic block is sleeved on the middle of the positioning rod, and one end of it is fixed to the inner wall of the fixed frame. Through the restoring force of the elastic block on the pushing block, the positioning rod is quickly locked after adjustment, ensuring operational stability.

[0009] Limiting structure design: A limiting groove is formed on the inner wall of one side of the second through hole, and a limiting slider is fixedly connected to one side of the positioning rod. The limiting slider is embedded in the limiting groove, which effectively prevents the positioning rod from rotating randomly during movement, further improving the stability of the limiting component.

[0010] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the relative angle between the brake lever and the towing disc is flexibly adjusted through the screw sleeve block and lead screw adjustment design, thereby making the span of the motorcycle handlebars adjustable to meet the personalized needs of different drivers for the handlebar position. At the same time, the screw thread adjustment method effectively prevents slippage and improves the stability of the angle between the brake lever and the towing disc.

[0011] 2. In this utility model, the design of the rotary scale groove on the surface of the lead screw corresponds to the indexing lock constructed by the locking slot hole, making the span adjustment process more intuitive. The driver can quickly and accurately adjust to the required position, improving the ease of use. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0015] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0016] The following is in conjunction with the appendix Figures 1-5 This invention describes an adjustable span motorcycle handlebar provided by some embodiments of the present invention.

[0017] like Figures 1 to 5 As shown, this utility model provides an adjustable span motorcycle brake lever, including a brake seat 100, a brake lever 200, and an adjustment guide rod 300. Specifically, it includes: a brake seat 100, a brake lever 200, and an adjustment guide rod 300. One end of the brake lever 200 is rotatably connected to a traction disc 210, which is rotatably mounted on the inner side of the brake seat 100. The surface of the traction disc 210 is provided with a pull hole 211 and a locking groove hole 212. The adjustment guide rod 300 includes a linkage lug 310 and a threaded sleeve block 320, which are rotatably mounted on the surfaces of the traction disc 210 and the brake lever 200, respectively, and a lead screw 330, which is rotatably mounted on one end of the linkage lug 310. The threaded sleeve block 320 is threaded onto the surface of the lead screw 330. The surface of the lead screw 330 is provided with a rotating wheel 340. One side of the brake seat 100 is threadedly mounted with an adjustment knob sleeve 120. A fixing ring 110 is fixedly connected to the surface of the brake seat 100, which is used to fix the brake seat 100 to the surface of the motorcycle handlebar.

[0018] In this embodiment, locking slots 212 are evenly distributed circumferentially on the outer periphery of the connecting shaft between the brake lever 200 and the brake seat 100. A spring pin is provided on the inner side of the brake lever 200 to abut against the surface of the locking slots 212. The relative position of the brake lever 200 and the traction disc 210 is locked after adjustment by the contact between the spring pin and the different locking slots 212. The connecting shaft between the linkage lug 310 and the surface of the traction disc 210 is coaxial with the connecting shaft between the traction disc 210 and the brake seat 100. A pull-tab hole 211 is used for connecting the brake cable, and the inner side of the adjusting knob sleeve 120 is provided for the brake cable to pass through.

[0019] In this embodiment, the lead screw 330 rotates perpendicular to the surface of the linkage lug 310, and the linkage lug 310, the threaded sleeve block 320, and the lead screw 330 are located on the same line. The threaded sleeve block 320 is threaded and threaded onto the surface of the lead screw 330. The adjusting guide rod 300 is radially arranged along the rotation direction of the traction disc 210 and is located in the same plane as the traction disc 210. The surface of the rotating wheel 340 is provided with graduated grooves, and the graduated grooves are evenly arranged circumferentially on the outer periphery of the rotating wheel 340.

[0020] One end of the brake lever 200 is rotatably connected to the brake seat 100 via a traction disc 210. The traction disc 210 is rotatably mounted on the inner side of the brake seat 100, and its surface is provided with several pull holes 211 and locking slots 212. The adjusting guide rod 300 includes a linkage lug 310 and a threaded sleeve block 320 respectively rotatably mounted on the surfaces of the traction disc 210 and the brake lever 200. The threaded sleeve block 320 is threaded onto the surface of the lead screw 330, and the surface of the lead screw 330 is provided with a rotating wheel 340. An adjusting knob sleeve 120 is threadedly mounted on one side of the brake seat 100, and a fixing ring 110 is fixedly connected to the surface of the brake seat 100 for fixing the brake seat 100 to the surface of the motorcycle handlebars.

[0021] In this embodiment, rotating the lead screw 330 causes the threaded sleeve 320 to engage with its thread, thereby changing the relative angle between the brake lever 200 and the traction disc 210, thus achieving the span adjustment function. The surface of the rotating wheel 340 is provided with graduated grooves, which, together with the locking hole 212, form an indexing mark, making the adjustment process intuitive and convenient. Simultaneously, the locking design of the locking hole 212, combined with the spring pin structure, can quickly lock the relative position of the brake lever 200 and the traction disc 210 after the span is adjusted, ensuring stability after adjustment.

[0022] Furthermore, the adjustment structure design of the adjusting guide rod 300 is optimized to make it suitable for a wider range of span adjustments, such as... Figure 3 As shown.

[0023] The linkage lug 310 is coaxially mounted with the traction disc 210 via a connecting shaft and is arranged perpendicularly to the lead screw 330, forming a more compact spatial layout. The screw sleeve block 320 is arranged radially along the rotation direction of the traction disc 210 and is located in the same plane as the traction disc 210 and the adjusting guide rod 300. By optimizing the structural arrangement of the adjusting guide rod 300, the adjusting components are made more compact and suitable for motorcycle handlebar structures of various sizes.

[0024] Specifically, the lead screw 330 rotates to engage the threaded sleeve 320, causing a change in the relative position between the brake lever 200 and the traction disc 210. Simultaneously, the pull-out hole 211, used to connect the brake cable, passes through the inner side of the adjusting knob sleeve 120, making the connection of the brake cable more stable and reliable. These improvements further enhance the compactness and practicality of the structure.

[0025] Furthermore, based on the above scheme, the design of the locking mechanism has been further optimized to improve the safety of the adjustment process.

[0026] The locking slots 212 are evenly distributed on the outer periphery of the connecting shaft between the traction disc 210 and the brake lever 200, and the inner side of the brake lever 200 is provided with a spring pin that abuts against the surfaces of the different locking slots 212 to achieve a quick locking function after adjustment. By increasing the number of locking points, the locking effect at different positions is ensured to be consistent, avoiding loosening or positional shift after adjustment.

[0027] Furthermore, during the adjustment process, the scale groove of the lead screw 330 engages with the raised indexing lock to form a clear visual identifier, allowing the driver to quickly identify the adjustment range and intuitively judge the adjustment result.
