Automobile auxiliary lamp capable of free rotation

Abstract

The invention provides a vehicle auxiliary lamp which can rotate freely, comprising a casing, a central processing unit, a light-emitting component, a power unit, a photo-detector, two limiting elements and an interlocking unit. Wherein, the interlocking element is arranged via two semi-gears on the shaft lever of steering wheel and meshed with driving gear to transfer the connection of said shaft lever; when the shaft lever rotates, the current value of variable resistor of interlocking element can increase with the rotated angle of shaft lever, while its voltage value is transmitted to the central processing unit which can judge and process said voltage signal to be transmitted to the power unit, then the power unit can synchronously rotate the light-emitting component with the shaft lever of steering wheel. The invention can be adjusted according to the angle change of steering wheel, which also has limiting elements to make a feedback signal judgment on the limits of left-right over angle or revolution angle after the free rotation of shading part of light-emitting component.

Description

Technical field [0001] The invention relates to a vehicle auxiliary lamp which can be rotated freely, in particular to a vehicle auxiliary lamp which can rotate a light-emitting element synchronously after the shaft of a steering wheel is rotated. Background technique [0002] In the driving safety of automobiles, in addition to observing the traffic rules, if drivers can master some safe driving essentials, the safety of travel will be greatly increased. [0003] Driving at night is often when the driver’s line of sight is the worst when the driver is driving. The most important thing is when the vehicle is moving, and the illumination angle of the headlight is fixed. For example, when driving on a curved road or a mountain road with poor conditions, The driver’s line of sight is more limited; or even when many drivers face multiple bends and the angle of up and downhill is too large, the blind spot of the visual range caused by the blind angle of the visual range, at this time,...

Problems solved by technology

[0003] Driving at night is often the time when the driver’s vision is the worst. The most important thing is that when the vehicle is driving, the angle of illumination of the headlights is fixed. For example, when driving on a curved road or on a mountain road with poor conditions, its The driver's line of sight is more limited; or it is the dead angle of the visual range caused by many drivers when they face many bends and the angle of uphill and downhill is too large. At this time, even if the lighting equipment with high brightness is used, it cannot be completely eliminated. this omission

[0004] Commonly used active steering headlights, their main feature is that they can steer themselves along with the direction of the vehicle, and their main function is to improve the angle of illumination of the headlights when the vehicle is turning, thereby improving the lighting effect of the corner and effectively reducing the risk of driving at night The projection angle of its active steering headlights will be adjusted with the angle of the steering wheel controlled by the driver. At the same time, the rotation direction of the lights is almost the same as the steering angle of the vehicle, and depending on the situation, the maximum rotation range of the headlights can be up to 1 2 degrees; and the main disadvantage of its composition is: the active steering headlight is integrated with the headlight of the vehicle, so its rotation angle is limited, and its cost is also high

[0005] It can be seen that the purchase cost of the above-mentioned commonly used items will still cause a lot of burden on the user, which is not a good design and needs to be improved urgently.
