Description

Technical Field

[0001] This invention relates to automotive lighting technology, and more particularly to an adjustable headlight for vehicles. Background Technology

[0002] Motorcycles are popular due to their long-distance riding capability, ease of use, and ability to reach areas inaccessible by cars. However, motorcycle headlights require adjustable beam angles to suit different riders. While current motorcycle headlights do offer angle adjustment, their design lacks a limiting mechanism, making them prone to accidental activation during riding. This can cause the headlight beam angle to shift, affecting the rider's ability to drive at night and potentially leading to accidents. Summary of the Invention

[0003] To address the shortcomings of the existing technology, this invention proposes an adjustable headlight for vehicles.

[0004] The technical solution of this invention is implemented as follows:

[0005] An adjustable headlight for vehicles, characterized in that it comprises:

[0006] An adjusting assembly includes a housing with an internally hollowed-out chamber. The chamber contains a first rotating component, a second rotating component, and an adjusting component. The adjusting component is positioned in the middle of the first rotating component and extends out of the chamber from one end of the housing. A limiting area is formed between the first and second rotating components. The first rotating component has symmetrically arranged first and second limiting grooves, and the second rotating component has a third limiting groove. The adjusting component consists of an adjusting part, an adjusting rod, and a limiting block. The limiting block is flush with the first, second, and third limiting grooves. The diameter of the adjusting part is larger than the diameter of the adjusting rod, and the adjusting part is located outside the housing. The second rotating component consists of a rotating end and a rotating rod. The third limiting groove is located on the rotating end. The rotating rod extends out of the chamber, and an adjusting end is located on one end of the rotating rod extending out of the chamber. A first spring is fitted onto the rotating rod, with one end contacting the rotating end and the other end contacting the inner wall of the chamber.

[0007] A drive assembly includes a base, a hinge, a hinge seat, a pusher, and a rotating component. The hinge seat is mounted on the base, which has a first positioning block and a second positioning block. The middle of the hinge is hinged to the hinge seat via a first hinge rod, and its lower end is hinged to one end of the pusher via a second hinge rod. The upper end of the hinge is tangentially in contact with a rotating rod. The pusher is positioned between the first and second positioning blocks, and its end away from the hinge has a movable hole with multiple limiting rods on its inner wall. One end of the rotating component is disposed within the movable hole, and its end with the movable hole has multiple sliding grooves that mate with the limiting rods. The rotating component also has a helical portion.

[0008] The lamp holder assembly includes a rotating shaft, a helical gear, and symmetrical fixing blocks. The rotating shaft is mounted on the fixing blocks, and the helical gear is mounted on one end of the rotating shaft. The helical gear meshes with a helical segment. A mounting block is provided on the rotating shaft, and a lampshade is provided on the mounting block.

[0009] Push the adjusting component to compress the first spring, then rotate the adjusting component to keep the limiting block engaged with the second limiting groove. Rotate the adjusting component to keep the upper end of the adjusting end from rotating, while the lower end pulls the pushing component. The component moves within the sliding groove through the limiting rod, keeping the rotating component rotating. The rotating component drives the helical gear to rotate, adjusting the illumination angle of the lampshade located on the rotating shaft.

[0010] In this invention, the housing is composed of an upper cover and a lower cover. The outer wall of the upper cover is provided with multiple elastic arms, and the elastic arms are provided with undercut portions. The outer wall of the lower cover is provided with an undercut groove that cooperates with the undercut portions. The inner walls of the upper cover and the lower cover are provided with limiting arc blocks. The outer wall of the first rotating member is provided with an annular groove, and the annular groove is installed in cooperation with the limiting arc block.

[0011] In this invention, the first rotating member has a through hole in the middle, and the first rotating member has a first plane and a first inclined plane on one end near the second rotating member. The first limiting groove is disposed on the first plane, and the second limiting groove is disposed on the second plane.

[0012] In this invention, the second rotating member is provided with a second plane and a second inclined plane, the third limiting groove is provided on the second plane, the maximum distance between the first plane and the second plane is H1, the maximum distance between the first inclined plane and the second inclined plane is H2, and H1 < H2.

[0013] In this invention, the adjusting end is provided with a protrusion, and the center line of the protrusion does not coincide with the center line of the rotating rod.

[0014] In this invention, the adjusting end is further provided with a notch, the upper end of the hinge end forms a mating part, and the mating part is provided with a notch that mates with the notch.

[0015] In this invention, the pusher is composed of a first rod, a second rod, and an annular body for connecting the first rod and the second rod. An installation area is formed in the middle of the annular body. A second spring is provided in the installation area. One end of the second spring contacts the inner wall of the installation area, and the other end contacts the hinge seat. The first rod is located between the first positioning block and the second positioning block. The second rod is hinged to the lower end of the hinge.

[0016] In this invention, the diameter of the limiting rod is smaller than the width of the sliding groove, and the bottom surface of the limiting rod does not contact the bottom surface of the sliding groove.

[0017] In this invention, the inner diameter of the movable hole is larger than the outer diameter of the rotating component.

[0018] In this invention, the sliding groove is composed of a straight segment and a spiral segment, and the straight segment and the spiral segment are connected by an arc segment.

[0019] The adjustable headlight for vehicles according to this invention has the following advantages: The adjustable headlight uses a mechanical structure to adjust the beam angle. Before adjustment, the adjustment component can be disconnected from the drive component, preventing accidental activation during driving and thus avoiding changes in the beam angle. When adjustment is needed, simply push the adjustment component to compress the first spring, rotate the adjustment component 180°, and then release the external force. This maintains contact between the adjustment end and the hinge in the drive component, allowing rotation of the adjustment component to adjust the beam angle. Its structure is stable, adjustment is convenient, and accidental activation is avoided, improving the ease of headlight angle adjustment. Attached Figure Description

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0035] like Figures 1 to 13 As shown, this adjustable headlight for vehicles includes an adjustment assembly 1, a drive assembly 2, and a lamp holder assembly 3. The adjustment assembly 1 controls the movement of the drive assembly 2, changing the position of the pusher 4 in the drive assembly 2, so that the pusher 4 drives the rotating member 5, which in turn drives the helical gear 6 in the lamp holder assembly 3 to rotate, thereby causing the rotating shaft 7 to rotate and causing the lamp body inside the lamp cover 8 to change the illumination angle.

[0036] The adjusting assembly 1 includes a housing 9, the interior of which is hollowed out to form an active chamber 10. The housing 9 consists of an upper cover 11 and a lower cover 12. The outer wall of the upper cover 11 has multiple elastic arms 13, each with a buckle 14. The outer wall of the lower cover 12 has a buckle groove 15 that mates with the buckle 14. Limiting arc blocks 16 are provided on the inner walls of the upper cover 11 and the lower cover 12. The outer wall of the first rotating component 17 has an annular groove 18, which mates with the limiting arc blocks 16.

[0037] Furthermore, through holes 19 are provided at both ends of the upper cover 11 and the lower cover 12 to facilitate the installation of the adjusting component 20 and the second rotating component 21.

[0038] During installation, first install the first spring 22, the first rotating member 17, the second rotating member 21, and the adjusting member 20 into the lower cover 12, and then install the upper cover 11 onto the lower cover 12, so that the positions of the first rotating member 17, the second rotating member 21, and the adjusting member 20 are defined.

[0039] The activity chamber 10 is provided with a first rotating component 17, a second rotating component 21 and an adjusting component 20. The adjusting component 20 is located in the middle of the first rotating component 17 and extends out of the activity chamber 10 from one end of the housing 9. A limiting area 23 is formed between the first rotating component 17 and the second rotating component 21.

[0040] The first rotating member 17 has a through hole 24 in the middle. The first rotating member 17 has a first plane 25 and a first inclined plane 26 on one end near the second rotating member 21. The first limiting groove 27 is provided on the first plane 25, and the second limiting groove 28 is provided on the second plane 29.

[0041] The second rotating member 21 is provided with a second plane 29 and a second inclined surface 30, and a third limiting groove 31 is provided on the second plane 29. The maximum distance between the first plane 25 and the second plane 29 is H1, and the maximum distance between the first inclined surface 26 and the second inclined surface 30 is H2, where H1 < H2.

[0042] The first rotating member 17 is provided with a first limiting groove 27 and a second limiting groove 28 symmetrically arranged, and the second rotating member 21 is provided with a third limiting groove 31. The adjusting member 20 is composed of an adjusting part 32, an adjusting rod 33 and a limiting block 34. The adjusting part 32 is provided with an indicator block 35 corresponding to the position of the limiting block 34, so that the position reached by the limiting block 34 can be seen from the indicator block 35.

[0043] The limiting block 34 is configured to cooperate with the first limiting groove 27, the second limiting groove 28, and the third limiting groove 31. When the limiting block 34 is in the first limiting groove 27 and the third limiting groove 31, the adjusting end 36 is not in contact with the hinge 37. When the limiting block 34 is in the second limiting groove 28 and the third limiting groove 31, the adjusting end 36 is in contact with the hinge 37. Rotating the adjusting member 20 drives the first rotating member 17 and the second rotating member 21 to rotate, thereby pushing the hinge 37 through the adjusting end 36.

[0044] The diameter of the adjusting part 32 is larger than the diameter of the adjusting rod 33, so that the adjusting part 32 is blocked by the housing 9 and will not enter the movable chamber 10, while also facilitating the rotation of the adjusting member 20. The adjusting part 32 is located outside the housing 9. The second rotating member 21 consists of a rotating end 38 and a rotating rod 39. A third limiting groove 31 is provided on the rotating end 38. The rotating rod 39 extends out of the movable chamber 10, and an adjusting end 36 is provided on one end of the rotating rod 39 extending out of the movable chamber 10. A first spring 22 is sleeved on the rotating rod 39. One end of the first spring 22 contacts the rotating end 38, and the other end contacts the inner wall of the movable chamber 10. A sliding area 67 is formed between the adjusting part 32 and the housing 9.

[0045] A protrusion 40 is provided on the adjusting end 36, and the center line of the protrusion 40 does not coincide with the center line of the rotating rod 39. A notch 41 is also provided on the adjusting end 36, and the upper end of the hinge 37 forms a mating part 43, which has a notch 44 that mates with the notch 41. Figure 13 As shown, when the adjusting end 36 is rotated in the direction of F1, the protrusion 40 on the adjusting end 36 reaches the upper end of the mating part 43, and then pushes the upper end of the hinge 37 to rotate downward, which in turn causes the lower end of the hinge 37 to rotate upward, thereby pushing the pushing member 4 towards the rotating member 5. When the adjusting end 36 is rotated in the direction of F2, the protrusion 40 on the adjusting end 36 reaches the lower end of the mating part 43, and then pushes the upper end of the hinge 37 to rotate upward, which in turn causes the lower end of the hinge 37 to rotate downward, thereby causing the hinge 37 to pull the pushing member 4, causing the pushing member 4 to move away from the rotating member 5. This allows the rotating member 5 to rotate clockwise or counterclockwise, facilitating angle adjustment of the lamp body located on the rotating shaft 7.

[0046] During adjustment, the adjusting member 20 needs to be pushed first so that the adjusting part 32 on the adjusting member 20 contacts the housing 9. Since the position of the first rotating member 17 remains unchanged, the first spring 22 will remain compressed, and the limiting area 23 will increase. Then, the adjusting member 20 is rotated 180°, and the external force applied to the adjusting member 20 is released. Under the elastic force of the first spring 22, the limiting block 34 on the adjusting member 20 is pushed into the second limiting groove 28, thereby reducing the distance between the first rotating member 17 and the second rotating member 21. The second rotating member 21 moves closer to the first rotating member 17, causing the second rotating member 21 to drive the adjusting end 36 towards the housing 9, so that the adjusting end 36 contacts the upper end of the hinge member 37. Before pressing and rotating the adjusting member 20, no matter how the adjusting member 20 is rotated, it will not push the hinge member 37 to rotate, thus preventing accidental activation.

[0047] The drive assembly 2 includes a base 45, a hinge 37, a hinge seat 46, a pusher 4, and a rotator 5. The hinge seat 46 is mounted on the base 45, which has a first positioning block 47 and a second positioning block 48. The first positioning block 47 has a first positioning hole 49 in the middle, and the second positioning block 48 has a second positioning hole 50 in the middle.

[0048] In actual use, the second positioning block 48 can be removed, and a third spring 52 can be set on the first rod body 51. One end of the third spring 52 contacts the first positioning block 47, and the other end contacts the ring body 53.

[0049] The middle of the hinge 37 is hinged to the hinge seat 46 via the first hinge rod 54, and the lower end is hinged to one end of the pusher 4 via the second hinge rod 55. The upper end of the hinge 37 is in tangential contact with the rotating rod 39.

[0050] The pusher 4 is positioned between the first positioning block 47 and the second positioning block 48. A movable hole 56 is provided on the end of the pusher 4 away from the hinge 37. The movable hole 56 is located on the first rod body 51, and multiple limiting rods 57 are provided on the inner wall of the movable hole 56. One end of the rotating member 5 is located within the movable hole 56, and the inner diameter of the movable hole 56 is larger than the outer diameter of the rotating member 5. A fixing block 66 can also be provided at the end of the rotating member 5 away from the pusher 4 to support it and improve the stability of the rotating member 5. Multiple sliding grooves 58 that mate with the limiting rods 57 are provided on the end of the rotating member 5 located in the movable hole 56. The rotating member 5 also has a spiral portion 59. The diameter of the limiting rod 57 is smaller than the width of the sliding groove 58, and the bottom surface of the limiting rod 57 does not contact the bottom surface of the sliding groove 58.

[0051] The sliding groove 58 consists of a straight section 60 and a spiral section 61. The straight section 60 and the spiral section 61 are connected by an arc section 62, and the limiting rod 57 is located inside the spiral section 61.

[0052] The pusher 4 consists of a first rod 51, a second rod 63, and an annular body 53 for connecting the first rod 51 and the second rod 63. A mounting area 64 is formed in the middle of the annular body 53. A second spring 65 is provided within the mounting area 64. One end of the second spring 65 contacts the inner wall of the mounting area 64, and the other end contacts the hinge seat 46. The first rod 51 is positioned between the first positioning block 47 and the second positioning block 48. The second rod 63 is hinged to the lower end of the hinge member 37.

[0053] The lamp holder assembly 3 includes a rotating shaft 7, a helical gear 6, and symmetrical fixing blocks 66. The rotating shaft 7 is mounted on the fixing blocks 66, and the helical gear 6 is mounted on one end of the rotating shaft 7. The helical gear 6 meshes with the helical segment 61. The rotating shaft 7 is provided with a mounting block 42, and the mounting block 42 is provided with a lamp cover 8. A lamp body (not shown in the figure) is installed inside the lamp cover 8, and the lamp body can be replaced.

[0054] When the lamp body angle needs to be adjusted, first push the adjusting part 20 to compress the first spring 22, then rotate the adjusting part 20. The rotation angle of the adjusting part 20 is 180°. Remove the applied external force and keep the limiting block 34 engaged with the second limiting groove 28. At this time, the adjusting end 36 is in contact with the upper end of the hinge 37. Then rotate the adjusting part 20, and the adjusting end 36 rotates in the direction of F2. Keep the adjusting end 36 pushing the upper end of the hinge 37 to rotate, while the lower end pulls the pushing part 4. It moves in the sliding groove 58 through the limiting rod 57, keeping the rotating part 5 rotating. The rotating part 5 drives the helical gear 6 to rotate, adjusting the illumination angle of the lamp cover 8 located on the rotating shaft 7.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
