DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] As Figure 1-2 shown, an automatically leveling low beam lamp module of the present utility model includes a mounting bracket 1 provided in a lamp socket. The mounting bracket 1 has an L-shaped structure. The lens assembly 8 is connected to the upper end of the mounting bracket 1 through a positioning bracket 7 to form an integrated structure. A light source positioning seat 4 is provided between the lens assembly 8 and the mounting bracket 1. The lower end of the light source positioning seat 4 is installed on the mounting bracket 1 through a gyro leveling seat 3. A gyroscope and a motor are provided in the gyro leveling seat 3. The upper end of the light source positioning seat 4 is rotatably connected to the positioning bracket 7 through a connecting block 6;

[0020] The light source positioning base 4 is fixed to the output end of the gyroscope leveling base 3 through the flange connecting sleeve 31. An elastic block 2 is provided at the connection between the gyroscope leveling base 3 and the mounting bracket 1. A light source board 9 is installed on one side of the light source positioning base 4. The gyroscope leveling base 3 is used to adjust the angle between the light source board 9 and the horizontal plane. A reflector 5 is provided outside the light source board 9. An LED lamp bead 91 is provided in the middle of the light source board 9 (see Figure 3 ). One end of the reflector 5 facing the lens assembly 8 forms a light outlet 51. Integral heat sinks 41 are evenly provided at the bottom of the light source positioning base 4 and on the side away from the light source board 9;

[0021] In the middle of the side of the connecting block 6 facing the lens assembly 8, there is a guide sleeve 61. The cross-section of the guide sleeve 61 is in a semi-circular ring shape. One end of the positioning bracket 7 close to the lens assembly 8 extends radially above the connecting block 6 to form a connecting plate 71. The connecting plate 71 is in a fan-shaped structure. A semi-circular ring-shaped guide groove 72 is machined on the bottom surface of the connecting plate 71 (see Figure 4 ). The guide sleeve 61 is inserted into the guide groove 72 in a matching manner. The central axis of the guide sleeve 61 coincides with the central axis of the output shaft of the gyroscope leveling base 3. The positions of the connecting block 6 and the connecting plate 71 are both set to avoid the reflector 5.

[0022] This structure adopts a double-positioning structure. One end of the light source positioning base with the light source board is installed on the bracket through the gyroscope leveling base, and the other end is rotatably connected to the positioning bracket through the connecting block. The structure is stable. The angle of the light source board is automatically adjusted by the gyroscope leveling base to achieve automatic leveling of the irradiation area, avoid the irradiation blind area caused by the vehicle body tilt, improve driving safety. During leveling, the guide sleeve on the connecting block rotates relative to the guide groove on the connecting plate for guiding, and the center of the light source positioning base is not easily offset, ensuring the leveling accuracy. The overall structure is simple and the installation is convenient.

[0023] During specific use, for the convenience of understanding the present invention, it is described in combination with the attached drawings:

[0024] The gyroscope leveling base is mainly used to adjust the angle between the light source board and the horizontal plane, so that the light source board on the light source positioning base is parallel to the horizontal plane. The reflector is located above the light source board, and the light output direction is the due front of the vehicle. During driving, when the vehicle body tilts to the left or right, the entire mounting bracket tilts synchronously with the vehicle body. After the gyroscope feeds back the tilt amount to the control system, the control system drives the motor to rotate, and the motor drives the entire light source positioning base to deflect in the opposite direction of the tilt direction, so that the area irradiated by the light always remains parallel to the road surface, and the irradiation range of the light on the road surface does not change.

[0025] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
