In order to realize the low cost, higher safety and larger irradiation range of the ADB + AFS function, a new combined installation mode is adopted. The main parts and the mounting mode are as follows:

as shown in fig. 3, the most important components of the ADB + AFS function are: the device comprises an ADB module assembly 3, an auxiliary high beam and low beam lamp module assembly 4, a stepping motor 6, a rotating support 7, a metal holding support 8, an ADB module fixing support 9, a lower half rotating mechanism 10 and an upper half rotating mechanism 11. The ADB module fixing support 9 is connected and assembled with the ADB module assembly 3, and the ADB module fixing support 9 is used for installing the ADB module assembly 3 and integrating the ADB module assembly 3 on the rotating support 7 through the connection and assembly relation of the ADB module fixing support 9 and the rotating support 7. The rotating bracket 7 is connected and assembled with the ADB module fixing bracket 9 on one hand, and is also connected and assembled with the metal holding bracket 8 on the other hand, the rotating bracket 7 is connected and assembled with the stepping motor 6 fixed on the metal holding bracket 8 on the other hand, and the rotating bracket 7 can rotate through the operation of the ball head of the stepping motor 6, so that the AFS function of the whole set of module disclosed by the invention is realized. Besides the above-mentioned relation of assembly and connection with the rotating bracket 7, the metal holding bracket 8 is also connected with the car lamp housing or other assembly parts connected to the car lamp housing, so that the whole set of modular module system is mounted and connected with the car lamp housing or integrated into the whole car lamp. Among them, a plan view of the lower half rotary mechanism 10 in fig. 3 is shown in fig. 4, a sectional view B-B in the plan view 4 is shown in fig. 5, and an exploded view of the upper half rotary mechanism 11 in fig. 3 is shown in fig. 6. The assembly relationship of the components is as follows:

the ADB module fixing bracket 9 is a part of the ADB module assembly 3, and is assembled and produced on a standardized and shared module production line. The stepping motor 6, the rotating bracket 7, the metal holding bracket 8, the lower half rotating mechanism 10 and the upper half rotating mechanism 11 belong to one part of the rotating structure sub-assembly 5, and are assembled and produced on a common module production line. After the ADB module subassembly 3 is assembled on the standardized common module manufacturing line and the ADB module subassembly 3 is assembled with the ADB module fixing bracket 9, it is mounted on the rotary structure subassembly 5 by 4 self-tapping screws St4 × 16. The auxiliary high beam and low beam module subassembly 4 is mounted on the rotary structure subassembly 5 by 4 self-tapping screws St4 × 16 after the assembly on the module production line. The main mounting modes of the lower half rotating mechanism 10 and the upper half rotating mechanism 11 on the rotating structure sub-assembly 5 are as follows:

the rotating mechanism mainly comprises an upper half part and a lower half part:

the top half mounting structure is shown in the top half swivel mechanism 11 of fig. 3, and the exploded view thereof is shown in fig. 6. The torsion spring 15 and the ball bearing 14 are firstly installed on the rotating bracket 7 and are locked by the bearing fixing screw 16, and the series of steps are completed. The finished rotary structural subassembly 5 is placed on the metal holding bracket 8, and the bearing bracket 13 is pressed against the metal holding bracket 8 and simultaneously locked by 2 machine-tooth screws 12.

The mounting structure of the lower part is shown in figure 4-a plan view of the lower part rotating mechanism. The mounting structure of the lower half is substantially similar to the mounting structure of the upper half. The rotating pin 17 and the ball bearing 14 are firstly installed on the rotating bracket 7, and are locked by the bearing fixing screw 16. After the series of steps is completed, the completed rotating structural sub-assembly 5 is placed on the metal holding bracket 8, and the bearing bracket 13 is pressed against the metal holding bracket 8 while being locked with 2 machine-tooth screws 12. The sleeve ball socket 18 is connected with the rotating pin 17 and the stepping motor 6.

Wherein: the stepping motor 6 is a source of force generation, the ball head seat 18 plays a good transition role for force transmission, the serial number 17-the rotating pin 17 plays a transition role for converting transverse pulling force into force rotating leftwards and rightwards, the ball bearing 16 plays a role in more smooth rotation for reducing friction force for rotation, and the torsion spring 15 provides restoring force for rotation, so that the rotation is more reliable.

The special rotation angles can be realized through the rotation mechanisms at the upper part and the lower part, the common AFS rotation angles in the market are inward 7.5 degrees and outward 15 degrees, and a schematic diagram of the common AFS rotation angles is shown in FIG. 7. However, the rotation angle of the module of this time is different from the normal one, the rotation angle is 12 degrees inward and 12 degrees outward, and the diagram of the rotation angle of the special AFS is shown in fig. 8. The transmission of force and the rotation are achieved as follows:

purely mechanical pushing means. The stepping motor 6 can stretch back and forth after receiving an electric signal, the ball head seat 18 is driven to form a pulling force in the stretching process, the ball head seat 18 transmits the pulling force to the rotating pin 17 and then converts the pulling force into a rotating force to transmit the rotating force to the rotating bracket 7, and the rotating bracket 7 drives the rotating part to rotate together. The manner of transmission of force and rotation for this is shown in fig. 9.

In order to make the whole module more stable when rotating, a metal holding bracket 8, a stepping motor 6 with larger thrust and a thicker torsion spring 15 are used. While at the time of design the center of gravity of the rotating part is as close as possible to the axis of rotation. Because the weight of the rotating part of the whole module reaches more than 1.2kg, the weight has certain difficulty and challenge to the vibration test of the whole module, and the aluminum alloy metal bracket is adopted through a plurality of times of simulation experiments. Meanwhile, as the total weight of the rotating part exceeds 1.2kg, in order to realize more stability and reliability in the AFS function, a larger stepping motor is adopted to provide larger back-and-forth pushing and pulling force, namely, a PL25 motor which can provide 25N thrust is changed into a PL35 motor which can provide 50N thrust. The use of a thicker torsion spring provides a greater restoring force, from a typical 1.0mm diameter spring to a 1.2mm diameter spring, where the restoring force can be increased from 1N m to 2N m, with a greater torque to make the turn back and forth more stable.

In order to reduce the investment in the production line and the design costs, an ADB module fixing bracket 9 is used. The ADB module fixing bracket 9 is an important component part in the ADB module component assembly 3, and the integrated installation and detection can be realized on a standard shared module production line by using the component, so that the production and design cost is reduced. Then, the ADB mold sub-assembly 3 is mounted on the rotary structure sub-assembly 5 by 4 screws in another production line which can be shared.
