Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicles, and particularly to a lighting module adjusting mechanism and a vehicle headlamp. Background Art
[0002] With the development of vehicle headlamp lighting technology, more and more vehicle manufacturers require diverse functions for headlamps, and the functions of high and low beams are required to be integrated with the signal lamp system as much as possible. Therefore, it poses a major challenge to the adjustment requirements of high and low beam modules.
[0003] In addition, smaller-sized vehicle headlamp lighting is an important direction for the future development of vehicle headlamps. It is required to arrange multiple lighting function areas within a smaller diameter range. For example, multiple reflecting bowls with auxiliary high and low beam functions are arranged along the circumference of a small-sized and ultra-narrow module. This makes multiple high-power functions concentrated in a small space, resulting in a gradual reduction in the space requirement behind the high and low beam modules and a gradual increase in the space requirement for the adjusting mechanism. At the same time, the requirement for accuracy in short-distance adjustment also needs to be ensured.
[0004] For the commonly used three-point adjusting mechanism, there are relatively large space limitation requirements. The Z-direction spacing of its adjusting screws determines the adjustment accuracy and the pitch of the screws. In an ultra-narrow module, it is difficult to increase the Z-direction adjustment spacing, which poses relatively high requirements and restrictive conditions on the pitch of the screws. Therefore, free arrangement cannot be achieved within the limited space, resulting in a relatively large space occupied by the relevant module adjusting mechanism. Moreover, the commonly used three-point adjustment requires matching ball head screws and related ball head bayonets for locking and matching. There are many and complex parts, the production and manufacturing costs are high, the assembly process is complex and time-consuming, and there is also great uncertainty about the reliability of the adjustment function. At the same time, the multi-layer adjustment scheme for matrix-type small-sized and ultra-narrow modules is complex. After multi-layer transmission, the processing accuracy of each layer is relatively high, and the adjustment is extremely cumbersome during production and use, and the overall weight of the parts is increased. Summary of the Invention
[0005] In view of this, the present application provides a lighting module adjusting mechanism and a vehicle headlamp. By adopting a sliding adjustment mode, the number of related parts is effectively reduced, the part strength is better solved, the complexity is reduced, the space requirement for adjustment is reduced, and at the same time, the position and angle of the sliding adjustment part can be flexibly arranged based on the space requirement, meeting the requirements of efficient utilization of lighting module parts and stepless adjustment in a small space.

DETAILED DESCRIPTION
[0036] The present application provides a lighting module adjustment mechanism and a vehicle headlight. By adopting a sliding adjustment mode, the number of related parts required is effectively reduced, and the strength of the parts is better solved and the complexity is reduced, thereby reducing the adjustment space requirement. At the same time, the position and angle of the sliding adjustment part can be flexibly arranged based on space requirements, so as to achieve efficient utilization of lighting module parts and infinite adjustment requirements in a small space.
[0037] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0038] The lighting module adjustment mechanism in the prior art includes a lighting module body, a fixed end, a horizontal ball head adjustment part and a vertical ball head adjustment part. The angle adjustment of the lighting module body in the horizontal and vertical directions is achieved by adjusting the horizontal ball head adjustment part and the vertical ball head adjustment part respectively.
[0039] like Figures 1 - 6As shown, the lighting module adjustment mechanism provided by the present application includes:
[0040] The lighting module main body;
[0041] The fixed end 6, fixedly connecting the bracket and the lighting module main body;
[0042] The ball head adjustment part 7, fixedly connecting the bracket and the lighting module main body, and capable of adjusting the angle of the lighting module main body in the horizontal direction;
[0043] The sliding adjustment part 8, including a sliding mechanism, a connecting structure, and a ball head screw 5;
[0044] The sliding mechanism includes a first sliding part and a second sliding part that are slidably connected. The first sliding part is connected to a certain part of the lighting module main body, such as a radiator, an internal support skeleton, or other module structures; the second sliding part is connected to the ball head part of the ball head screw 5 through the connecting structure, and the ball head screw 5 is connected to the bracket through a nut. Adjusting the position of the ball head screw 5 relative to the nut can make the second sliding part slide relative to the first sliding part and can adjust the angle of the lighting module main body in the vertical direction.
[0045] The lighting module adjustment mechanism of the present application adopts a sliding adjustment mode. The first sliding part can be combined with the lighting module main body, such as a radiator, an internal support skeleton, or other module structures, etc., without the need to additionally set up connecting parts, effectively reducing the required number of related parts, and better solving the part strength and reducing the complexity, avoiding the problem of space occupation of the three-point adjustment in the prior art, that is, reducing the required adjustment space; and the sliding adjustment part does not have the requirement of being fixedly set somewhere. It can be set on the radiator, or on the internal support skeleton, or other module structures, as long as the relative sliding and adjustment functions are satisfied. Therefore, the Z-direction adjustment structure, that is, the setting of the sliding adjustment part, can flexibly arrange the position and angle of the sliding adjustment part 8 based on its shaping requirements and the overall space requirements, meeting the requirements of efficient utilization of lighting module parts and stepless adjustment in a small space.
[0046] In a preferred embodiment, as Figures 10 - 12 shown, the first sliding part is the adjustment slide rail 2, and the second sliding part is the adjustment slider 1. The adjustment slider 1 can slide along the length direction of the adjustment slide rail 2.
[0047] Through the sliding method of matching the adjustment slide rail 2 with the adjustment slider 1, a simple, efficient, structurally compact, and stable performance adjustment method is realized; among them, the adjustment slide rail 2 is a straight type. Of course, in necessary cases, a curved slide rail can also be used.
[0048] In a preferred embodiment, as Figures 10 - 12As shown, the adjustment slide rail 2 includes a first rail 21 and a second rail 22. A chute for the adjustment slider 1 to slide is formed between the first rail 21 and the second rail 22. The adjustment slider 1 can slide within the chute and is not prone to lateral displacement.
[0049] In a preferred embodiment, as Figures 10 - 12 shown, the adjustment slider 1 includes a first support portion 11, a second support portion 12 arranged in parallel with each other, and a slide rod portion 13 arranged between the first support portion 11 and the second support portion 12. As Figure 10 shown, the cross-sections of the first support portion 11, the second support portion 12, and the slide rod portion 13 can be H-shaped. In this way, when the slide rod portion 13 is inserted into the chute formed by the first rail 21 and the second rail 22, the first support portion 11 and the second support portion 12 can prevent the adjustment slider 1 from disengaging from both ends of the slide rod portion 13.
[0050] In a preferred embodiment, as Figures 10 - 12 shown, a first support spring piece 111 and a second support spring piece are provided on the lower surface of the first support portion 11. The first support spring piece 111 abuts against the upper surface of the first rail 21, and the second support spring piece abuts against the upper surface of the second rail 22; and / or, a first support protrusion 121 and a second support protrusion are provided on the upper surface of the second support portion 12. The first support protrusion 121 abuts against the lower surface of the first rail 21; the second support protrusion abuts against the lower surface of the second rail 22.
[0051] The first support spring piece 111 and the first support protrusion 121 can make the first support portion 11 and the second support portion 12 fit with the first rail 21, avoiding excessive gaps between the adjustment slide rail 2 and the adjustment slider 1 and causing up-and-down shaking when they slide relative to each other. Among them, the deformation degree of the first support spring piece 111 is larger, and the deformation amount of the first support protrusion 121 is smaller. The two cooperate with each other to ensure a proper fit between the first rail 21 and the adjustment slider 1; similarly, the second support spring piece and the second support protrusion can make the first support portion 11 and the second support portion 12 fit with the second rail 22, avoiding excessive gaps between the adjustment slide rail 2 and the adjustment slider 1 and causing up-and-down shaking when they slide relative to each other. Among them, the deformation degree of the second support spring piece is larger, and the deformation amount of the second support protrusion is smaller. The two cooperate with each other to ensure a proper fit between the second rail 22 and the adjustment slider 1.
[0052] In a preferred embodiment, as Figures 10 - 12As shown, the connecting structure includes a transition support rib 3 and a locking structure 4 that are connected to each other. The locking structure 4 can be C-shaped or hemispherical and can wrap the spherical head of the ball screw 5. The spherical head of the ball screw 5 is embedded in the locking structure 4 and can rotate relative to the locking structure 4. When adjusting the ball screw 5 relative to the nut, that is, when the ball screw 5 is adjusted left and right, the locking structure 4 can move left and right accordingly and rotate relative to the spherical head.
[0053] One end of the transition support rib 3 is fixedly connected to the locking structure 4, and the other end of the transition support rib 3 is rotatably connected to the lower surface of the second sliding part, which can avoid jamming when the second sliding part slides relative to the first sliding part.
[0054] In a preferred embodiment, as Figures 7 - 9 shown, one end in the length direction of the adjustment slide rail 2 is connected to the radiator of the lighting module main body, and / or a limiting device is provided at the other end in the length direction of the adjustment slide rail 2.
[0055] One end in the length direction of the adjustment slide rail 2 is connected to the radiator, combined with the internal support skeleton or other structures of the lighting module main body, making rational use of space, effectively reducing the required number of related parts, and better solving the part strength and reducing the complexity.
[0056] The limiting device at the other end in the length direction of the adjustment slide rail 2 can prevent the adjustment slider 1 from disengaging along the length direction of the adjustment slide rail 2.
[0057] Specifically, as Figures 7 - 9 shown, the adjustment process of the adjustment slide rail 2 is as follows:
[0058] As Figure 7 shown, the ball screw 5 is in the middle position, and the adjustment slider 1 is in the middle of the adjustment slide rail 2. At this time, the lighting module main body is in the middle position in the vertical direction.
[0059] As Figure 8 shown, the ball screw 5 is adjusted forward, that is, the ball screw 5 approaches the lighting module main body, and the adjustment slider 1 is at the frontmost position of the adjustment slide rail 2 (the position close to the lighting module main body), and the lighting module main body is adjusted upward accordingly.
[0060] As Figure 9 shown, the ball screw 5 is adjusted backward, that is, the ball screw 5 moves away from the lighting module main body, and the adjustment slider 1 is at the rearmost position of the adjustment slide rail 2 (the position far from the lighting module main body), and the lighting module main body is adjusted downward accordingly.
[0061] In a preferred embodiment, as Figures 7 - 9As shown, there is an angle between the adjusting rail 2 and the radiator, that is, the adjusting rail 2 is tilted relative to the surface of the radiator, so that a larger angle adjustment of the adjusting rail 2 can be achieved with a smaller extension and contraction amount of the ball screw 5 relative to the nut, thereby driving a larger angle adjustment of the lighting module.
[0062] In a preferred embodiment, Figure 13 As shown, the adjustment range R of the adjustment rail 2 in the vertical direction satisfies: 0°<R≤60°.
[0063] By adjusting the telescopic amount of the ball screw 5 relative to the nut and transmitting the component of the sliding adjustment part 8, the different design angles of the adjustment rail 2 are matched to achieve adjustment requirements of different precisions. If the adjustment angle is too large, it is necessary to set a longer adapter support rib 3 and a longer telescopic amount of the ball screw 5 relative to the nut. Therefore, in this embodiment, it is appropriate to set the adjustment range R of the adjustment rail 2 in the vertical direction between 0-60 degrees. In this way, the adjustment range of the lighting module body in the vertical direction is also between 0-60 degrees.
[0064] The present application also provides a vehicle headlight, including the above-mentioned lighting module adjustment mechanism, which can more reasonably arrange the space inside the headlight and improve the lighting efficiency of the vehicle headlight.
