[0025] The far and near beam shape adjustment device of the automobile headlamp of the present invention includes a fixed bracket 1, an adjusted component 2 and an adjustment mechanism 3. The fixed bracket 1 is fixedly connected to the low beam unit, and the adjusted component 2 is fixedly connected to the remote The light unit adjusts the relative position of the brightest point of the high-beam unit with respect to the low-beam shape through the adjustment of the adjusted components by the adjustment mechanism, and then adjusts the angle between the fixed bracket and the lamp body to realize the high-beam shape and the near-beam shape. Synchronous adjustment of light shape.
[0026] Such as Figure 2 ~ Figure 3 As shown, 1a is a fixed ball head, 1b is an elastic waist groove, 2a is a cylindrical inner hole, 2b is a guide post, 2c is an adjusting rod, and 3a is a through hole.
[0027] One end of the adjusted component 2 is fixedly provided with an adjusting rod 2c, the adjusting rod 2c is inclined upwardly 15-20 degrees with respect to the horizontal plane, and the other end of the adjusted component 2 is fixedly provided with a guide post 2b on both sides, two guides A fixed ball head 1a is fixedly arranged between the posts 2b. One end of the fixed bracket 1 and the adjusted component 2 is provided with an elastic waist slot 1b that cooperates with the guide posts 2b, and a matching ball head 1a is provided between the two elastic waist slots 1b. Cylindrical inner hole 2a. The ends of the two guide posts 2b are respectively located in the corresponding elastic waist grooves 1b, and the two elastic waist grooves 1b respectively clamp the two guide posts 2b to limit the rotational deviation of the adjusted component 2 along the cylindrical inner hole 2a . The fixed ball head 1a is located in the cylindrical inner hole 2a to limit the radial deviation of the adjusted component 2 along the cylindrical inner hole 2a.
[0028] The cylindrical inner hole 2a cooperates with the fixed ball head 1a to limit the radial offset of the adjusted component. The adjusted component can be adjusted with the axial direction of the guide column as the rotation axis through the cooperation of the guide post 2b and the elastic waist groove 1b. Rotation within 3 degrees up and down. The guide post 2b cooperates with the elastic waist hole slot 1b to limit the rotational deviation of the adjusted component. The adjusted component can be rotated around the cylindrical inner hole 2a through the cooperation of the cylindrical inner hole 2a and the fixed ball head 1a. The axis rotates within 3 degrees of left and right.
[0029] The adjustment mechanism 3 is an up, down, left, and right adjustment mechanism. One side of the adjustment mechanism is provided with a through hole 3a that is matched with the adjustment rod 2c. The end of the adjustment rod and the through hole is spherical, and the adjustment rod 2c The spherical end is inserted into the through hole 3a. The through hole 3a is a cylindrical through hole. The adjusting rod 2c is adjusted by the adjusting mechanism 3 to drive the adjusted component to the axial and cylindrical inner hole of the guide column. The axial direction of 2a is that the rotating shaft rotates up, down, left and right relative to the fixed bracket.
[0030] Such as Figure 4 ~ Figure 6 As shown, the up, down, left and right adjustment mechanism in this embodiment is a screw-driven two-way adjustment mechanism. Among them, 4 is the slider, 5 is the gear, 6 is the left and right adjustment screw, 7 is the rack structure, 8 is the sliding groove, 9 is the upper and lower adjustment screw, 9a is the groove, 10 is the first circlip, 11 is the second Circlip, 12 is a semi-thread structure.
[0031] The screw-driven two-way adjustment mechanism includes a sliding block 4 provided with a cavity, a gear 5, left and right adjustment screws 6 and up and down adjustment screws 9. A rack structure 7 meshing with one side of the gear 5 is provided in the cavity of the sliding block, and the other side of the gear 5 meshes with the left and right adjustment screws 6, and the left and right adjustment screws 6 pass through the second circlip 11 It is fixed with the slider 4, and at the same time, the left and right adjustment screws 6 can rotate in the axial direction. The through hole 3a is arranged in the center of the gear 5. Through the cooperation of the through hole 3a and the adjusting rod 2c, the left and right adjustment screws 6 are adjusted in the forward or reverse direction, and the drive gear rolls left and right along the rack structure, and the gear rolls left and right. During the process, the adjusting rod 2c is driven to move to realize the left and right adjustment of the adjusted component 2 relative to the fixed bracket 1.
[0032] The fixing bracket 1 is provided with a sliding groove 8, and the sliding groove 8 is arranged in the sliding groove 8. The sliding groove 8 is an open box-shaped sliding groove, and a semi-threaded structure 12 is provided on one side of the sliding block 4. The half-thread structure and the upper and lower adjusting screw 9 arranged on the same side of the slider 4 form a thread pair. The upper and lower adjusting screw 9 is fixed to the slider 4 by the first circlip 10, and the groove 9a on the head of the upper and lower adjusting screw 9 is locked into the The upper edge of the sliding groove 8 fixes the upper and lower adjusting screw 9 relative to the sliding groove 8 in its axial direction. Through the cooperation of the through hole 3a and the adjusting rod 2c, the upper and lower adjusting screw 9 is adjusted forward or backward to drive the slider 4. The gear 5 and the left and right adjustment screws 6 move up and down in the chute 8. When the gear 5 moves up and down, the adjustment rod 2c is moved to realize the up and down adjustment of the adjusted component 2 relative to the fixed bracket 1.
[0033] In other embodiments, the up, down, left, and right adjustment mechanism may not adopt a screw drive mode, as long as the up, down, left, and right adjustment can be achieved.
[0034] The success of the present invention lies in the use of the cylindrical inner hole 2a to cooperate with the fixed ball head 1a and the cooperation of the two elastic waist grooves 1b and the two guide posts 2b to form the adjusted component 2 in the axial direction of the cylindrical inner hole 2a and The axial rotation shafts of the two cylindrical guide posts 2b are adjusted by the adjustment mechanism 3 to the adjustment rod 2c to realize the up, down, left and right adjustment of the adjusted component 2 relative to the fixed support 1.
[0035] The present invention has a compact structure. At the same time, the low beam unit is fixed to the fixed bracket 1, and the high beam unit is fixed to the adjusted component 2. After adjusting the position of the brightest light of the high beam unit with respect to the low beam shape through the adjustment mechanism 3, Then, by adjusting the angle between the fixing bracket 1 and the lamp body, the synchronous adjustment of the high beam shape and the low beam shape is realized. It solves the problem of the existing adjusting device because the high beam unit and the low beam unit belong to different brackets and adjustment systems, so the space size is large, and when the illumination angle of the low beam unit is adjusted, the brightest point of the high beam illumination light shape will deviate from the low beam The problem of light shape.
