Description

Technical Field

[0001] This utility model relates to the field of motor vehicle structure technology, specifically to an angle-adjustable motorcycle handlebar. Background Technology

[0002] With the widespread use of motorcycles in urban transportation and personalized travel, their handling performance and riding comfort have become key indicators of user concern. As a crucial component of the motorcycle's control system, the handlebars directly affect the rider's operating posture and handling stability. Traditional motorcycle handlebars generally adopt a fixed structure, meaning the handlebars are fixed to the frame by bolts or welding. This structure is simple, has low manufacturing costs, and is widely used in ordinary two-wheeled vehicles.

[0003] In some technical solutions, to achieve a certain range of angle adjustment, some handlebars are designed with a rotating shaft or a geared sprocket structure at the mounting point, and the angle is adjusted by manually tightening or loosening bolts. However, this type of structure has the following obvious problems:

[0004] The adjustment precision is low, and the angle control is unstable. The mechanical limit method, which relies on manual operation, is easily affected by installation errors, wear, or impact, causing the handlebars to loosen or shift during use, which is detrimental to safe driving.

[0005] The lack of an angle adjustment feedback mechanism is a significant drawback. Most current technologies lack effective angle detection and display systems, leaving users unable to clearly determine the handlebar's current angle. Adjustments rely heavily on experience, impacting operational accuracy and user experience.

[0006] In conclusion, existing motorcycle handlebars still have significant limitations in terms of structural design, adjustment precision, ergonomics, and intelligent interaction. There is an urgent need for an improved handlebar structure that combines structural innovation with intelligent control to meet users' multiple needs for driving comfort, safety, and a sense of technology. Utility Model Content

[0007] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0008] Therefore, the technical solution adopted by this utility model is as follows: an angle-adjustable motorcycle handlebar, comprising: a fixed base, a handlebar stem, and a bushing. The bushing is fixedly installed on the surface of the fixed base, and a drive motor is fixedly installed on the surface of the fixed base. A worm gear ring located inside the bushing is fixedly sleeved on the surface of the handlebar stem. The worm gear ring and a first worm are rotatably installed inside the bushing, and the bottom end of the first worm is fixedly connected to the output end of the fixed base. The first worm engages with the surface of the worm gear ring for transmission, and a second worm engages with the surface of the worm gear ring for transmission. The two ends of the handlebar extend horizontally, and a continuous curved transition section is provided in the middle to form a stepped lifting structure. This structure can achieve flexible adjustment of the overall angle without affecting the grip feel, improving driving comfort and handling flexibility.

[0009] In one possible implementation, the first worm and the second worm are symmetrically arranged on the upper and lower sides of the worm gear ring, and mesh with the upper and lower sides of the worm gear ring respectively. The surfaces of both the first and second worms are provided with worm sleeves that mesh with the surface of the worm gear ring. This symmetrically arranged double worm structure enhances the stability and balance of handlebar rotation control, avoiding uneven wear and rotation.

[0010] In one possible implementation, the surface of the second worm is provided with worm ridges that mesh with two worm gears on the surface of the second worm, and the helical directions of the two worm ridges are opposite. This structural design allows for a more compact fit in the rotational directions, applies mutually counteracting torques to the worm gear ring drive, and ensures better positioning accuracy and anti-interference capability of the handlebar during adjustment.

[0011] In one possible implementation, the handlebar is a one-piece curved structure, and the handlebar extends through the surface of the axle housing. This structure improves the overall strength and structural stability of the handlebar, reduces machining steps at the connection points, and facilitates assembly and maintenance.

[0012] In one possible implementation, the surface of the mounting base is provided with a touch switch, and the surface of the handlebar is provided with a limiting protrusion. During the rotation of the handlebar, the contact between the limiting protrusion and the touch switch is used to detect the rotation angle of the handlebar. Providing a limiting feedback signal through physical detection improves the reliability of position judgment during handlebar angle adjustment and simplifies the design of the electronic feedback system.

[0013] In one possible implementation, the drive motor is a stepper motor or a servo motor, and its forward and reverse directions are controlled by a controller to achieve precise adjustment of the handlebar angle. This drive solution has the advantages of fast response and high precision, which helps to realize automated and intelligent handlebar angle adjustment functions.

[0014] In one possible implementation, a display component is embedded in the top surface of the axle housing to display the rotation angle of the handlebar in real time. This visual interface provides feedback to the user on the current handlebar angle, improving the interactive experience and adjustment accuracy, and enhancing the user-friendliness of the human-computer interaction.

[0015] The beneficial effects achieved by this utility model are as follows:

[0016] 1. In this utility model, the handlebar is an integrally formed curved rod structure. The stepped geometric transition achieves an ergonomic grip posture. The grip posture can be adjusted during deflection. It adopts a worm gear ring and double worm meshing structure. The drive motor drives the worm to rotate, which can achieve stable adjustment of the motorcycle handlebar angle. It not only has high transmission efficiency, but also a smooth and reliable adjustment process, avoiding the low precision and jamming problems caused by traditional mechanical limit methods.

[0017] 2. In this utility model, by setting a physical cooperation structure between the limiting protrusion and the touch switch, the real-time detection of the handlebar angle position is realized, which effectively simplifies the angle feedback system, reduces manufacturing and maintenance costs, and sets a display component on the top of the axle box to provide real-time feedback on the current handlebar angle information, improves the human-computer interaction, and allows users to obtain information more intuitively and accurately during the adjustment process, thereby improving the user experience.

[0026] 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.

[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0028] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an angle-adjustable motorcycle handlebar.

[0029] Combination Figures 1-5 As shown, the present invention provides an angle-adjustable motorcycle handlebar, including a fixed base 100, a handlebar 200, and an axle box 300.

[0030] The mounting base 100 is the basic structure for mounting and supporting the handlebar assembly. It is installed on the motorcycle's front fork or handlebars, and a drive motor 110 is fixedly mounted on its surface. The output end of the drive motor 110 is connected to the first worm gear 320 to provide the power source for angle adjustment. The drive motor 110 can be a stepper motor or a servo motor, which performs forward and reverse rotation under the control of a controller, thereby driving the worm gear system to rotate and achieve precise adjustment of the handlebar angle.

[0031] The axle box 300 is a structural component used to install the transmission assembly and limit the rotation path of the handlebars. It is fixedly installed on the upper surface of the mounting base 100, and a worm gear ring 310, a first worm 320, and a second worm 330 are rotatably mounted inside it. The worm gear ring 310 is fixedly sleeved on the outer surface of the handlebar 200, so that when the worm gear ring 310 rotates, it can drive the handlebar 200 to rotate synchronously, thereby realizing the function of adjusting the handlebar angle.

[0032] The bottom end of the first worm 320 is fixedly connected to the output end of the fixed base 100, and is used to transmit the rotational torque generated by the drive motor 110 to the worm gear ring 310. The surface of the first worm 320 is provided with a worm sleeve, which meshes with the surface of the worm gear ring 310 to drive the worm gear ring 310 to rotate.

[0033] The surfaces of the second worm 330 and the worm ring 310 are also in a meshing transmission relationship to enhance transmission stability. The second worm 330 and the first worm 320 are symmetrically arranged on the upper and lower sides of the worm ring 310. Both worms have worm sleeves on their surfaces, which mesh with the surface of the worm ring 310 to form a bidirectional meshing transmission structure.

[0034] Furthermore, such as Figure 3 and Figure 4As shown, the surface of the second worm 330 is provided with two worm ridges, which mesh with the worm wheels on the corresponding worm gear ring 310 for transmission. The helical directions of the two worm ridges are opposite, forming a symmetrical meshing structure, which is beneficial to the torque balance and meshing anti-interference performance during transmission.

[0035] like Figure 1 , Figure 2 As shown, the handlebar 200 is a one-piece curved structure extending in the left-right direction. Both ends extend horizontally, and the middle section features a stepped, geometrically curved transition to enhance the naturalness and comfort of the rider's grip. The handlebar 200 extends through the surface of the axle housing 300, meaning it is fixed to the worm gear ring 310 and protrudes from both sides of the axle housing 300.

[0036] like Figure 2 As shown, to detect the handlebar rotation angle, a touch switch is provided on the surface of the mounting base 100, and a limit protrusion 210 is provided on the surface of the handlebar 200. When the handlebar 200 rotates with the worm gear ring 310, the limit protrusion 210 will touch the touch switch within a certain angle range, thereby outputting a position signal to determine the current rotation angle of the handlebar. This physical limit feedback method does not require a complex circuit structure and is simple and reliable.

[0037] like Figure 3 As shown, a display component is embedded in the top surface of the axle housing 300 to display the rotation angle of the handlebar 200 in real time. This display component can be a common electronic display device such as an LCD screen or an LED digital tube to provide visual feedback on the angle information, making it easier for users to observe the current handlebar posture and achieve more precise adjustment operations.

[0038] Through the coordinated operation of the above structures, this utility model can achieve continuous adjustment of the motorcycle handlebar angle, with the advantages of stable structure, precise adjustment and clear feedback. It is suitable for various riding posture requirements and effectively improves driving safety and comfort.
