Embodiment Construction

[0029] like Figure 1-3As shown, the headlamp 1 of the present invention includes a housing 2 and an internal mechanism 3 . The internal mechanism 3 includes: a main frame 12; a low beam 14 suspended on the main frame 12 through a rotating hinge, and the low beam also has a lens group 16; a high beam 18 directly installed on the main frame 12, the high beam The light lamp also has a lens group 20; and first and second trimmers 4 and 6 fixed to the housing 2 in a substantially horizontal direction for suspending the main frame 12. The first trimmer 4 includes: a co-point trimming unit 22 fixed on the shell 2; a screw rod 24 engaged in the co-point trimming unit 22 and whose front end is a suspension head; and fixed on the main frame 12 to carry the suspension head. Suspension seat 26. The suspension head at the front end of the screw rod 24 forms a ball head, and a spherical socket is formed in the suspension seat 26, so that the ball head and the spherical socket form a free...

Abstract

The invention discloses a head light and a method for controlling deflection of illumination direction thereof. The head light comprises a casing, a first trimmer, a second trimmer, a main frame, a dipped head light, a far reaching light, a first linear drive motor and a microprocessing unit, wherein the first trimmer and the second trimmer are fixed on the casing along the same horizontal line; the main frame is pivoted to the first trimmer and the second trimmer so as to be hung in the shell, the dipped head light is pivoted on the main frame, the far reaching light is fixedly arranged on the main frame, the linear drive motor is fixed on the casing, comprises a first output shaft coupled to the main frame, and pushes the main frame to rotate around the center line formed by connecting points of the first trimmer and the second trimmer as well as the main frame through the telescopic motion of the first output; and the microprocessing unit is electrically connected to the first linear drive motor to control the first linear drive motor. The invention also discloses a method for controlling the deflection of illumination direction of the head light.

Description

technical field [0001] The invention relates to a vehicle headlight, in particular to a headlight whose illumination direction can be deflected, and a control method for the deflection of the illumination direction. Background technique [0002] In order to enable the driver to see the objects ahead more clearly to increase driving safety, the lighting direction of the headlights of the vehicle usually needs to be adjusted according to the driving state of the vehicle. At present, there are many kinds of headlights including left-right and up-down power rotation actuators on the market, which realize the rotation of the lighting direction of the headlights in different ways. These rotary actuators include: a gear chain transmission mechanism, a worm gear mechanism or a link mechanism (for example, a flexible link mechanism) and the like. In order to enable these rotary actuators to effectively implement the rotary action, these mechanisms are required to provide functions s...
