Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of motorcycle, especially a motorcycle headlamp. BACKGROUND

[0002] With the continuous development of modern transportation tools, the driving safety and comfort of motorcycles are attracting more and more attention. As an important part of night driving, the performance of motorcycle headlamps directly affects the driver's field of view and driving safety. Traditional motorcycle headlamps usually adopt a fixed-angle design, whether it is a halogen lamp, an LED lamp, or a xenon lamp, the illumination range is usually limited to the area directly in front of the vehicle. However, when the motorcycle is turning, going uphill or downhill, or tilting, the body angle will change accordingly, and the fixed-angle headlamp design often cannot fully illuminate the actual required field of view of the driver, resulting in an increase in the blind area, thus increasing the risk of accidents.

[0003] Currently, some high-end cars have been equipped with adaptive front-lighting systems (AFS), which can adjust the beam angle according to the turning direction, speed, and inclination angle of the vehicle, etc. to provide more accurate lighting. However, in the motorcycle field, due to the light body, large dynamic changes, and space and cost limitations, similar technologies have not been widely used. Especially for the unique tilting steering mode of motorcycles, there is currently a lack of technology that can compensate for the illumination range in real time according to the body inclination angle. When driving on a curve, due to the body tilt, the beam of the traditional headlamp cannot effectively cover the inside area of the curve, resulting in limited field of view for the driver, greatly increasing the safety hazards of night driving.

[0004] Therefore, there is an urgent need for a headlamp that can dynamically adjust the light compensation according to the body angle of the motorcycle. This technology not only improves the lighting effect at night and in complex road conditions, but also provides a safer driving experience for the driver, filling the gap in the current motorcycle headlamp technology.

[0005] In order to solve the above problems, the Chinese invention patent with application number CN202211050014.5 proposes a motorcycle lighting lamp control system, which comprises: a headlamp, a vehicle body and a lampshade, the lampshade is fixedly connected with the front end of the vehicle body, the headlamp is fixed in the lampshade, further comprising: a compensation lamp, a warning lamp, a gyroscope and a controller, the compensation lamp is rotatably connected with the vehicle body, the warning lamp is fixed on the vehicle body, the gyroscope and the controller are located on the vehicle body, the gyroscope is used for measuring the inclination angle of the vehicle body and the ground surface, and transmitting the detected inclination angle signal to the controller, the controller is used for receiving the inclination angle signal, analyzing and judging the inclination angle, controlling the compensation lamp to rotate and emit compensation light, and controlling the warning lamp to emit warning. But the gyroscope of this application needs to be installed on the vehicle body, which will cause large workload during installation, and different structures of motorcycles have different technical requirements for technicians, so the labor consumption will be large.

DETAILED DESCRIPTION

[0024] The technical scheme of the utility model will be further specifically explained below through examples and in combination with the drawings.

[0025] Example:

[0026] With the continuous development of modern transportation, the driving safety and comfort of motorcycles are attracting more and more attention. As an important part of night driving, the performance of motorcycle headlamps is directly related to the driver's field of view and driving safety. Traditional motorcycle headlamps usually adopt a fixed angle design, whether halogen, LED or xenon, their illumination range is usually limited to the area directly in front of the vehicle. However, when the motorcycle is turning, climbing or tilting, the body angle will change accordingly, and the fixed angle of the headlamp design often cannot fully illuminate the actual field of view required by the driver, resulting in an increase in the blind area, thereby increasing the risk of accidents.

[0027] Currently, some high-end cars have been equipped with adaptive front-lighting systems (AFS), which can adjust the beam angle according to the turning direction, speed and inclination of the vehicle, etc. to provide more accurate lighting. However, in the motorcycle field, due to the light body, large dynamic changes, and space and cost restrictions, similar technology has not been widely used. Especially for the unique tilting steering mode of motorcycles, there is currently a lack of technology that can compensate for the illumination range in real time according to the body inclination. When driving on a curve, due to the body tilt, the light beam of the traditional headlamp cannot effectively cover the inside area of the curve, resulting in limited visibility for the driver, greatly increasing the safety hazards of night driving.

[0028] Therefore, there is an urgent need for a headlamp that can dynamically adjust the light according to the angle of the motorcycle body. This technology not only improves the lighting effect under night and complex road conditions, but also provides a safer driving experience for the driver, filling the gap in current motorcycle headlamp technology.

[0029] In order to solve the above problems, the utility model provides a motorcycle headlamp, aiming at improving the lighting effect of motorcycle in different driving environment, especially when the vehicle is turning, tilting or driving on uneven road, through the function of automatic light compensation, to ensure that the driver can clearly observe the changes of the road and the surrounding environment in front, thereby improving the safety of night driving, including circuit board 11 and headlamp mounting bracket 3, circuit board 11 is equipped with six-axis rotation sensor 12, which is used for real-time sensing the angle change of motorcycle body. This six-axis rotation sensor 12 can accurately monitor the three-dimensional space motion state of the motorcycle during driving, including the inclination angle, turning angle and acceleration of the vehicle, etc. Through these high-precision sensing data, the device can quickly adjust the illumination direction and brightness of the headlamp according to the state of the body, thereby realizing the function of automatic light compensation. The headlamp mounting bracket 3 is also provided with a headlamp group, and the six-axis rotation sensor 12 and the headlamp group are electrically connected, so as to dynamically adjust according to the real-time data transmitted by the six-axis rotation sensor 12.

[0030] The front light group comprises a left light group 4 and a right light group 5 arranged symmetrically. This symmetrical design can well match the body structure of the motorcycle and the lighting needs. When the vehicle is tilted to the left or right, the brightness and irradiation range of the left light group 4 or the right light group 5 is adjusted respectively to ensure that the light can accurately cover the driver's blind area.

[0031] Specifically, the left light group 4 comprises a plurality of rectangular left front lights arranged from bottom to top. These left front lights are arranged in order from bottom to top. Such arrangement can accurately provide light compensation for the left side view when the motorcycle is tilted by lighting different height left front lights. Similarly, the right light group 5 comprises a plurality of rectangular right front lights arranged from bottom to top. These right front lights are also arranged in order from bottom to top. When the motorcycle is tilted to the right, the design of the right light group 5 can provide corresponding light compensation effect for the right side view by lighting different right front lights.

[0032] In addition, in order to further improve the lighting effect and overall performance of the motorcycle front light, the middle of the left light group 4 and the right light group 5 is also provided with a front light low beam lens 6 in the shape of a rounded equilateral triangle, and the left front light and the right front light are arranged along the two waists of the front light low beam lens. The design of the front light low beam lens 6 aims to optimize the lighting effect in front, ensuring that the driver can still obtain stable, uniform and bright front lighting in the straight driving state of the vehicle. The low beam lens can effectively reduce the scattering and loss of light, thereby improving the utilization efficiency of light and avoiding the problem of glare to the drivers of oncoming vehicles.

[0033] The lower part of the front light group and the front light low beam lens 6 is also provided with a rectangular front light high beam lens 7. The overall structure aims to meet the multifunctional needs of the vehicle lighting system. As an important part of the vehicle, the design of the front light group not only needs to meet the basic lighting function, but also needs to consider the aesthetics, durability and convenience of installation. The front light low beam lens 6 is mainly used to provide the near distance lighting function of the vehicle when driving at night. Its light beam distribution range is wide, which can effectively cover the near distance area in front of the vehicle, ensuring that the driver has a clear observation of the road conditions. Below the low beam lens, the front light high beam lens 7 is specially arranged, which mainly provides long distance lighting support for the vehicle. The high beam lens focuses light beams and projects them to a farther road surface, so that the driver can clearly see the obstacles or road conditions in the distance in the absence of oncoming traffic or in a relatively open road environment, thereby further improving the safety of driving.

[0034] The front light mounting bracket 3 is also provided with an arc-shaped front night light lampshade 8, a V-shaped front night light left lampshade 9 and a V-shaped front night light right lampshade 10. These lampshades are designed to protect the internal structure of the front night light from external environmental influences such as rain, dust or other particulate matter. In addition, the material of the lampshades is usually polycarbonate material with high light transmittance, and the surface is specially hardened, which has strong wear resistance and ultraviolet resistance, thereby prolonging the service life of the lampshade and ensuring the transmission effect of the light.

[0035] The circuit board 11 and the front light mounting bracket 3 are connected by several hexagonal screws. This design not only provides reliable mechanical strength, but also facilitates subsequent disassembly and maintenance. The hexagonal screws in the utility model are usually made of stainless steel or other corrosion-resistant materials to adapt to the use conditions of vehicles exposed to external environments for a long time.

[0036] The side of the circuit board 11 away from the front light mounting bracket 3 is sequentially provided with a front light socket and a front light rear shell 1 with a circular groove. The front light socket is a fixed component of the front light source, and its design needs to meet the requirement of accurate positioning to ensure that the light source can accurately cooperate with the reflector and lens to achieve the best optical effect. The material of the socket is usually high-temperature resistant plastic or ceramic material to ensure that it will not deform or be damaged in a long-term high-temperature working environment. The front light rear shell 1 is the external protective structure of the entire front light group, which can provide comprehensive protection for the internal optical and electronic elements. The design of the rear shell needs to consider the air tightness and heat dissipation, usually made of aluminum alloy or other metal materials, and the heat dissipation fins or ventilation holes are designed at the key positions to ensure the normal working temperature of the front light group.

[0037] The front light rear shell 1 is provided with a front night light inner cover and an instrument air permeable film. The main function of the front night light inner cover is to provide additional shading and protection for the front night light, and its design needs to be closely matched with the front night light lampshade 8 to ensure effective control of light and optimization of optical effect. The function of the instrument air permeable film is to provide the necessary ventilation function for the front light group. Since the vehicle may produce water vapor or condensation in the internal of the front light group due to temperature difference during operation, the air permeable film allows air to circulate while blocking moisture from entering, thereby effectively avoiding the phenomenon of internal fogging and ensuring the optical performance and service life of the front light group.

[0038] The headlamp mounting bracket 3 is provided with a headlamp cover on the side away from the circuit board 11. The headlamp cover is an important component in the headlamp structure, and its main function is to isolate and protect the various parts inside the headlamp, while also providing fixed points and support for the installation of other components. The headlamp cover is provided with grooves to accommodate the headlamp group, the headlamp low-beam lens 6, the headlamp high-beam lens 7, the headlamp cover 8, the headlamp left cover 9, and the headlamp right cover 10. This multi-groove design not only improves the assembly efficiency of the headlamp, but also ensures the stability and sealing of the installed components. The position and size of each groove are precisely designed to ensure that each component fits perfectly, thereby improving the overall performance of the headlamp.

[0039] The headlamp cover is provided with a headlamp cover 2 on the side away from the headlamp mounting bracket 3. The headlamp cover 2 is located at the outermost layer of the entire headlamp, and its main function is to protect the internal optical components from the external environment, including dust, rain, mud, etc. At the same time, the headlamp cover 2 also has good light transmission performance to ensure that the light source can fully penetrate the cover and provide clear and bright lighting effects. The edge connection between the headlamp cover and the headlamp cover 2 is provided with a headlamp waterproof ring. The function of the headlamp waterproof ring is to seal the entire headlamp assembly to prevent external water, dust, and other impurities from entering the interior of the headlamp, thereby affecting the normal operation of the internal components. The material of the waterproof ring is usually rubber or silicone with high elasticity and weather resistance to ensure that it can maintain good sealing effect in various harsh environments. The edge of the headlamp cover 2 is also provided with a headlamp decorative frame and a headlamp decorative ring. The main function of these decorative structures is to improve the aesthetics of the headlamp, making it better integrated into the overall appearance design of the vehicle. The headlamp decorative frame and decorative ring are usually made of high-quality plastic or metal, and their surfaces are treated with special processes such as electroplating, spraying, polishing, etc., which not only increases the durability of the decorative parts, but also gives the headlamp a more delicate and fashionable appearance. The design style of the decorative frame and decorative ring is usually determined according to the overall styling and positioning of the vehicle, both conforming to the overall design language of the vehicle and fully showing the unique personality of the headlamp.

[0040] Working principle:

[0041] When the vehicle is tilted, in order to ensure the lighting needs and driving safety of the vehicle under different tilt angles, the headlamp system will automatically adjust the lighting state according to the tilt angle, thereby providing more accurate road lighting effect for the driver. When the vehicle tilts to the left by more than 5 degrees, the system will automatically detect this tilt state and quickly start the first left headlamp on the left side, ensuring that the vehicle can provide basic compensation lighting effect in the case of slight left tilt, so that the driver can timely sense the road conditions. If the vehicle continues to tilt to the left to reach 10 degrees or more, it means that the vehicle tilt degree is intensified, at this time the second left headlamp on the left side will also be automatically turned on, working together with the first left headlamp to further strengthen the lighting range of the left side, thereby providing the driver with a clearer view. If the left tilt angle of the vehicle increases to more than 15 degrees, this tilt condition is already a relatively obvious state, the system will automatically turn on the third left headlamp on the left side, which works together with the previous two left headlamps to more comprehensively cover the left side lighting area, further improving the driving safety. When the left tilt angle of the vehicle continues to increase to more than 20 degrees, this is a relatively extreme tilt condition, at this time the system will turn on the fourth left headlamp on the left side, which forms a powerful lighting effect in combination with the previous three lights, maximally compensates the left side view, helps the driver to cope with complex road environment and avoid potential dangers.

[0042] Moreover, the system also considers the right tilt of the vehicle in design and has a completely symmetrical function with the left side. When the vehicle tilts to the right, the lighting logic of the headlamp is completely consistent with the rules on the left side. For example, when the vehicle tilts to the right by more than 5 degrees, the first right headlamp on the right side will be automatically turned on; when the right tilt reaches more than 10 degrees, the second right headlamp on the right side will be turned on; if the right tilt angle reaches more than 15 degrees, the third right headlamp on the right side will be started; and when the right tilt angle reaches more than 20 degrees, the fourth right headlamp on the right side will also be turned on. This symmetrical lighting compensation function ensures that whether the vehicle tilts to the left or to the right, the intelligent light adjustment can provide balanced and efficient lighting support for the driver, greatly improving the driving safety and driving experience. This design fully considers the complexity of the actual driving of the vehicle and provides all-round safety protection for the driver.
