Description

Headlights that automatically correct the projection angle

The present invention relates to a headlight that automatically corrects a projection angle, and is particularly suitable for a two-wheeled vehicle such as a locomotive or a bicycle, or other vehicle having a tilting steering lamp.

Vehicles for two-wheeled vehicles, such as locomotives or electric bicycles or bicycles, are equipped with a headlight to provide safe lighting at night or in the dark, but conventional headlights are fixedly mounted directly in front of the vehicle. Whether the car is turning or tilting, the lights can only be projected in a single fixed direction. It is impossible to maneuver and change with the difference in the environment, position or angle of the car body, especially when the car passes through the turning road. The projection direction is only biased to one side, and it cannot be corrected to change its projection direction or angle with the turning of the road and the inclination of the vehicle body. Therefore, the light cannot be accurately projected to the inner lane of the turn or the center of the road, and the illumination area will change due to the angle. However, it is narrowed, resulting in insufficient illumination and unclear sight, and the danger is relatively increased, making it difficult to provide safe lighting.

To this end, the applicant filed an invention patent application with the aid of No. 095147012 "Auxiliary device for automatically correcting the projection angle of the headlights", and was awarded the invention No. I312848, but the applicant's previous case was for the traditional bulb type structure. The headlights are improved, and they are not suitable for LED junctions. The vehicle headlights, developed by the applicant, are designed to provide a combination of traditional bulb-type headlights and LED headlights, with automatic correction of the projection angle.

The main purpose of the present invention is to provide a headlight that can automatically correct a projection angle, comprising a lamp body, a fixed bottom plate, a lamp holder and a driving motor, such as a headlight of an LED type structure. The system includes a heat dissipation module base, an LED bracket and an LED lighting component, and the fixed bottom plate is locked at the rear end of the LED lamp body, and the headlight fixing seat is adapted to be coupled to the LED lamp body and the driving motor, and cooperates with The horizontal sensor and a controller can instantly detect and transmit the steering data of the headlights when the headlights of the locomotive are turned, so as to automatically change the projection direction of the headlights by a controller command driving the motor, so that the LED headlights are turning The best forward projection angle can be maintained at any time while traveling, providing sufficient illumination to enhance ride safety.

A second object of the present invention is to provide a headlight that can automatically correct a projection angle, and can automatically adjust the optimal forward projection angle of the modified headlight with the steering of the locomotive head and the roll of the vehicle body. The optimal level of projection angle allows the headlights to yaw and correct the projection direction and angle with the turning of the road and the roll of the body, so that the light of the headlight can be completely projected to the inner lane or the center of the road, providing better performance. Lighting vision, greatly improving driving safety.

The 21 series is disposed at the central position, and the eccentric design of the drive shaft 41 of the drive motor 4 is combined, and an offset angle is generated between the drive shaft 41 and the axis of the fixed bottom plate 2', thereby rotating the drive shaft 41. At this time, the fixed bottom plate 2' and the entire headlight can be simultaneously rotated and biased toward a specific side (left side or right side) to solve and automatically correct the projection offset occurring when the body roll is performed.

Similarly, the detection of the body roll and the transmission of the data (angle) are also configured by the level sensor 5 and the controller 6, and when the body is tilted, the detection is performed at any time, and the headlights are automatically corrected. The offset angle of the projection enables the headlight to maintain an optimal forward and optimal horizontal projection angle while traveling, providing a better illumination field of view and increasing vehicle safety.

As shown in the twenty-second and twenty-third figures, it is a schematic diagram showing the projection state of the present invention in the straight direction of the vehicle, the projection surface A1 is completely projected on the ground; and the twenty-fourth and twenty-fifth As shown in the figure, it shows The present invention is a schematic diagram of the projection state of the vehicle during cornering. Although the projection surface A2 has turned, it can still maintain a complete projection on the ground; in the embodiments of the first to eighth embodiments of the present invention, the above-mentioned progressive effects are obtained.

As shown in the twenty-sixth and twenty-seventh drawings, the display shows the hair The projection diagram of the vehicle when it is in the eccentric state at the same time when the vehicle is in the state of roll and turn, the projection surface A3 has turned and is tilted, but still can completely maintain the projection on the ground, that is, the projection surface A3 does not With the roll of the vehicle body, it is narrowed into a narrow and narrow shape; as in the embodiment shown in the fifteenth to twenty-first embodiments of the present invention, the axial collar 21' of the fixed bottom plate 2' is The eccentric design is adopted, so that when the drive shaft 41 rotates, the fixed bottom plate 2' and the entire headlight can be simultaneously rotated and biased toward a specific side (left side or right side), thereby having the double advancement effect as described above.

As shown in the twenty-eighth and twenty-ninth figures, the projection diagram of the conventional headlight B is in the state of roll and turn at the same time, and the conventional headlight B is projected because of the roll of the vehicle body. The projection of the surface B1 may cause a deviation phenomenon, so that the projection surface B1 becomes narrower, that is, the light actually projected on the ground has been narrowed and narrowed, and the projection direction is inconsistent with the turning direction of the headlight B, and when turning The light cannot be widely projected to the inner lane or the center of the road, nor can it turn in parallel with the headlight B, so the vision is poor and the safety is not good.
