They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The following is combined with Figure 1-6 The utility model is further described.

[0031] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an adjustable automobile ADB headlight, comprising a lamp housing 1 and a lampshade 2 fixedly connected to the outside of the lamp housing 1, a sealing strip is provided on the outside of the lampshade 2, and the lampshade 2 and the lamp housing 1 are detachably fixedly connected by screws.

[0032] In a specific technical solution, a lamp holder 3 is provided in a lamp housing 1, and the lamp housing 1 and the lamp holder 3 are connected by an angle adjustment mechanism 20, and the lamp holder 3 is adjusted in angle in the lamp housing 1 by the angle adjustment mechanism 20, and a lamp bead 4 is fixedly connected to the lamp holder 3 for emitting light. The lamp bead 4 is in the vehicle system, and the ADB adjustment system (Android Debug Bridge) is used to realize automatic adjustment of the high beam to avoid dazzling other vehicles and pedestrians, and at the same time ensure that the driver has a better field of vision when driving at night;

[0033] ADB composition: The ADB system includes a forward ADB camera, an intelligent high beam enable switch, an intelligent headlight control module, a LIN drive control module on the left and right headlights, an LED high beam group, and communicates with the entire vehicle through the bus to obtain the signals required for the algorithm.

[0034] ADB function: The ADB function is activated when the intelligent light enable switch is turned on. When the high-beam switch signal is valid, the ADB camera collects the angle of the forward or target vehicle and sends it to the intelligent headlamp control module. The intelligent headlamp control module calculates the high-beam lamp group that needs to be turned off through a specific algorithm and sends it to the headlamp LIN drive control module through the LIN bus. The module drives the corresponding lamp beads to light up or turn off.

[0035] The adjustment mechanism 20 includes an articulated assembly 19 and a fixed seat 8. The articulated assembly 19 is used to articulate the lamp holder 3 in the lamp housing 1. The fixed seat 8 is detachably fixed in the lamp housing 1 by screws and is located behind the lamp holder 3. The fixed seat 8 has a universal ball 18 rotatably connected thereto. The universal ball 18 passes through an adjustment rod 5 that is fixedly connected thereto. One end of the adjustment rod 5 is fixedly connected to the lamp holder 3. The fixed seat 8 is also provided with a driving assembly that drives the universal ball 18 to rotate. The universal ball 18 is driven to rotate by the driving assembly, thereby driving the lamp holder 3 and the lamp bead 4 to adjust their angles.

[0036] Specifically, the lamp holder 3 is hinged to the inner side of the lamp housing 1 by the hinge assembly 19, so as to disperse the weight of the lamp holder 3, avoid the weight of the lamp holder 3 being concentrated on one end of the adjustment rod 5, and further improve the service life of the adjustment rod 5. The hinge assembly 19 can be a hinge groove provided on the lamp housing 1 and a hinge column provided on the lamp holder 3, and the hinge column cooperates with the hinge groove to complete the hinge connection; of course, those skilled in the art understand that the hinge assembly 19 can also be a ball screw fixed on the lamp housing 1 and a ball seat fixed on the lamp holder 3, and the ball seat cooperates with the ball screw to complete the hinge connection. The other end of the adjusting rod 5 passes through the universal ball 18 and is rotatably connected to the rotating column 11. A groove 12 is provided on the outside of the rotating column 11, and a rotating shaft 13 is rotatably connected in the groove 12. In the present embodiment, the driving component is an electric push rod 7, and the electric push rod 7 is a micro electric push rod. The electric push rod 7 can also be replaced by other linear motion mechanisms as long as the above functions can be achieved. The piston rod of the electric push rod 7 is rotatably connected to the rotating shaft 13. Specifically, the outside of the slider 9 is fixedly connected to a hinge seat 10, and a pin is rotatably connected in the hinge seat 10, and the tail of the electric push rod 7 is fixedly connected to the pin.

[0037] The above technical solution is explained as follows: when the electric push rod 7 is pushed to work, it drives the universal ball 18 to rotate, so that the angle of the lamp holder 3 and the lamp bead 4 can be adjusted.

[0038] Among them, the fixed seat 8 is a cylindrical structure, and an annular slide rail 6 is fixedly connected to the outside of the fixed seat 8. An inner groove 15 is provided in the annular slide rail 6, and a gear ring 14 is fixedly connected in the inner groove 15. A slider 9 is slidably connected in the annular slide rail 6. A recess is provided in the slider 9, and a gear 17 is rotatably connected in the recess. A motor 16 is also fixedly connected in the recess. The motor 16 is a micro motor 16. The motor 16 drives the gear 17 to rotate. The gear 17 is meshed with the gear ring 14, so that the slider 9 can slide and adjust in the annular slide rail 6, and the driving shaft of the motor 16 is fixedly connected to the gear 17. The tail of the electric push rod 7 is hinged to the outside of the slider 9.

[0039] In order for those skilled in the art to fully understand the technical solution, this embodiment is summarized as follows:

[0040] When in use, the lamp beads 4 can be used to illuminate, and then the ADB adjustment system (Android DebugBridge) can be used to achieve automatic adjustment of the high and low lights;

[0041] If it is necessary to adjust the angle of the lighting, just start the motor 16 to drive the gear 17 to rotate. The gear 17 meshes with the ring gear 14, allowing the slider 9 to slide and adjust in the annular slide rail 6. The slider 9 will also drive the electric push rod 7 to rotate and adjust synchronously. The rotating column 11 will also rotate and adjust on the outside of the adjusting rod 5. For example, when it is adjusted to the right side of the universal ball 18, when the electric push rod 7 is started and extended, it can push the rotating column 11 to drive the adjusting rod 5 to rotate to the left, thereby driving the lamp holder 3 and the lamp bead 4 to rotate to the left to achieve adjustment. By analogy, the angle adjustment of the lamp bead 4 can be completed, which is suitable for different environments.

[0042] The standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the prior art.
