Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more specifically, to an automotive headlight lens adjustment structure, an automotive headlight, and an automotive. Background Technology

[0002] With the development of automotive lighting, the use of multi-lens systems has become increasingly widespread, enabling headlights to evolve from traditional single low beams and single high beams to dual low beams or dual high beams, resulting in richer display effects. Currently, automotive lenses are generally fixedly mounted on the headlight housing. When multiple lenses are used, assembly errors exist between them, and the fixed lenses cannot be adjusted, which can easily lead to dark spots in the light, poor illumination, and even affect driving safety. Summary of the Invention

[0003] The present invention aims to solve the technical problem of poor lighting effect of existing automotive multi-lens lamps.

[0004] On one hand, the present invention proposes an automotive headlight lens adjustment structure, including at least two lens brackets and corresponding first adjustment components. The lens brackets are used to install lenses, and the first adjustment components are correspondingly arranged with the lens brackets. The first adjustment components include three ball head screws, one end of which is connected to the corresponding lens bracket, and the other end of which is used to connect to the headlight housing. The three ball head screws are arranged in a triangle, and at least two of the three ball head screws are fine-tuning ball head screws, which are used to rotate to drive the lens bracket to rotate relative to the headlight housing.

[0005] The automotive headlight lens adjustment structure of this invention has a lens mounted on a lens bracket, which is then mounted on the headlight housing via a first adjustment component. Since the three ball-head screws of the first adjustment component are located at the three vertices of a triangle, and at least two are fine-tuning ball-head screws, when one of the fine-tuning ball-head screws is rotated, it rotates in and out relative to the headlight housing. The other two ball-head screws are fixed rotation points, and the line connecting these two fixed rotation points (i.e., one side of the triangle) forms the rotation axis. One end of the lens bracket rotates around this rotation axis in a first direction. Similarly, when adjusting the other fine-tuning ball-head screw, the lens bracket rotates around the line connecting the other two ball-head screws in a second direction. The rotation axes of the first and second directions are different, meaning they do not coincide. This allows for fine-tuning of the rotation of a single lens bracket and its corresponding lens in different directions. With one lens stationary, adjusting the other lenses sequentially using the above method ensures that the optical center points of all lenses are aligned, improving illumination, resolving dark spots, and compensating for assembly errors of multiple lenses.

[0006] Optionally, the three ball head screws are a first fine-tuning ball head screw, a second fine-tuning ball head screw, and a fixed ball head screw, wherein the first fine-tuning ball head screw, the second fine-tuning ball head screw, and the fixed ball head screw are arranged in a right-angled triangle, and the fixed ball head screw is located at the right-angle vertex;

[0007] When the first fine-tuning ball head screw is rotated, the line connecting the second fine-tuning ball head screw and the fixed ball head screw forms a first rotation axis, and the lens bracket rotates around the first rotation axis in a first direction. When the second fine-tuning ball head screw is rotated, the line connecting the first fine-tuning ball head screw and the fixed ball head screw forms a second rotation axis, and the lens bracket rotates around the second rotation axis in a second direction. The first direction is perpendicular to the second direction.

[0008] Optionally, the automotive headlight lens adjustment structure further includes a second adjustment component, wherein each of the first adjustment components is used to be mounted on the headlight housing via the same second adjustment component.

[0009] Optionally, the second adjustment component includes a first sliding bracket and a second sliding bracket disposed opposite to each other. The first sliding bracket and the second sliding bracket are slidably connected to the headlight housing. The first fine-tuning ball head screw is connected to the first sliding bracket, and the second fine-tuning ball head screw is connected to the second sliding bracket.

[0010] When the first sliding bracket slides relative to the headlight housing, all the lens brackets rotate around the second fine-tuning ball head screw and the fixed ball head screw in the first direction; when the second sliding bracket slides relative to the headlight housing, all the lens brackets rotate around the first fine-tuning ball head screw and the fixed ball head screw in the second direction.

[0011] Optionally, the second adjustment assembly further includes an adjustment screw, one end of which is connected to the first sliding bracket or the second sliding bracket. The first sliding bracket or the second sliding bracket is provided with a limiting block, and the headlight housing is provided with a limiting groove adapted to the limiting block. The limiting groove extends along the length direction of the adjustment screw, and the limiting block is placed in the limiting groove. When the adjustment screw rotates, the first sliding bracket or the second sliding bracket is used to slide relative to the headlight housing through the limiting block and the limiting groove.

[0012] Optionally, the end of the adjusting screw away from the first sliding bracket or the second sliding bracket is used to extend out of the headlight housing.

[0013] Optionally, the first fine-tuning ball head screw is provided with a limiting piece along the circumferential direction, and the first sliding bracket is provided with a baffle, the baffle being used to abut against the limiting piece.

[0014] On the other hand, the present invention also proposes an automotive headlight, including a lens, a headlight housing, and the aforementioned automotive headlight lens adjustment structure, wherein the lens is mounted on the headlight housing via the automotive headlight lens adjustment structure. The advantages of this automotive headlight compared to the prior art are the same as those of the aforementioned automotive headlight lens adjustment structure, and will not be repeated here.

[0015] Optionally, the car headlight also includes a plug, and the headlight housing has an adjustment hole at a position corresponding to the fine-tuning ball screw of the car headlight lens adjustment structure, and the plug is installed at the adjustment hole.

[0016] Furthermore, the present invention also proposes an automobile, including the aforementioned headlights. The advantages of this automobile compared to the prior art are the same as those of the aforementioned headlights, and will not be repeated here. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fitting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0028] In addition, it should be noted that in the description of the present invention, terms such as "upper," "lower," "front," and "rear" used to indicate orientation in various embodiments are only for simplifying the description of the positional relationships based on the accompanying drawings and do not mean that the elements and devices referred to must be operated in accordance with the specific orientation and limited operation, method, and structure in the specification. Such directional terms do not constitute a limitation on the present invention.

[0029] This paper establishes a coordinate system XYZ, where the positive direction of the X-axis represents the front and the negative direction of the X-axis represents the back; the positive direction of the Y-axis represents the left and the negative direction of the Y-axis represents the back; the positive direction of the Z-axis represents the top and the negative direction of the Z-axis represents the bottom.

[0030] like Figure 1-3 As shown, this embodiment of the invention provides an automotive headlight lens adjustment structure, including at least two lens supports 1 and at least two first adjustment components 2. The lens supports 1 are used to mount lenses 4. The first adjustment components 2 are correspondingly arranged with the lens supports 1. The first adjustment components 2 include three ball head screws. One end of each ball head screw is connected to the lens support 1, and the other end is used to connect to the headlight housing 5. The three ball head screws are arranged in a triangle, and at least two of the three ball head screws are fine-tuning ball head screws. The fine-tuning ball head screws are used to rotate to drive the lens support 1 to rotate relative to the headlight housing 5.

[0031] In this embodiment, the headlights illuminate forward, which is the direction indicated by the positive X-axis. Figure 7 As shown, lens 4 can be bolted to lens bracket 1, and lens bracket 1 is installed inside headlight housing 5 via first adjustment component 2. The rear end of lens bracket 1 has three mounting holes, the axis of which is in the direction shown by the X-axis. One end of the ball head of ball head screw is inserted into the mounting hole, and the threaded end of ball head screw is screwed into headlight housing 5.

[0032] Rotating the fine-tuning ball head screw, which extends into and out of the headlight housing 5 along the X-axis, exemplarily, one of the three ball head screws is located at the upper end of the lens bracket 1, and the other two are located at the lower end. When the upper ball head screw is the fine-tuning ball head screw, i.e., it can rotate, the upper end of the lens bracket 1 rotates around the two lower ball head screws in the front-back direction. The line connecting the mounting points of the two lower ball head screws, i.e., one side of the triangle, constitutes the rotation axis of the lens bracket 1. The principle is similar when rotating one of the lower ball head screws; it also rotates around the other two ball head screws. Rotating each fine-tuning ball head screw individually allows for the adjustment of a single lens in different directions.

[0033] When there are multiple lenses inside the headlight housing 5, one lens 4 can be kept stationary, and the other lenses 4 can be adjusted in sequence using the adjustment method of a single lens described above. This will make the optical center point of all lenses 4 consistent, improve the lighting effect, solve the problem of dark spots in the lighting, and compensate for the assembly error of multiple lenses.

[0034] Moreover, the adjustment method using a fine-tuning ball head screw is simple and convenient, which can reduce the development requirements of the lens bracket mold and improve the product qualification rate.

[0035] like Figure 2-3 As shown, optionally, the three ball head screws are a first fine-tuning ball head screw 21, a second fine-tuning ball head screw 22, and a fixed ball head screw 23. The first fine-tuning ball head screw 21, the second fine-tuning ball head screw 22, and the fixed ball head screw 23 are arranged in a right-angled triangle, and the fixed ball head screw 23 is located at the right-angle vertex.

[0036] When the first fine-tuning ball head screw 21 is rotated, the line connecting the second fine-tuning ball head screw 22 and the fixed ball head screw 23 forms a first rotation axis, and the lens bracket 1 rotates around the first rotation axis in a first direction. When the second fine-tuning ball head screw 22 is rotated, the line connecting the first fine-tuning ball head screw 21 and the fixed ball head screw 23 forms a second rotation axis, and the lens bracket 1 rotates around the second rotation axis in a second direction. The first direction is perpendicular to the second direction.

[0037] In this embodiment, the lens holder 1 can be roughly square, with the three ball head screws located at three vertices. The first fine-tuning ball head screw 21 and the fixed ball head screw 23 are spaced apart along the Y-axis, and the second fine-tuning ball head screw 22 and the fixed ball head screw 23 are spaced apart along the Z-axis. The first fine-tuning ball head screw 21 can be located to the right of the fixed ball head screw 23, and the second fine-tuning ball head screw 22 can be located above the fixed ball head screw 23.

[0038] The fixed ball head screw 23 does not rotate and can serve as a rotation support point. When the first fine-tuning ball head screw 21 rotates relative to the headlight housing 5, it drives the right end of the lens bracket 1 to rotate from right to left around the second fine-tuning ball head screw 22 and the fixed ball head screw 23 at the left end of the lens bracket 1. When the second fine-tuning ball head screw 22 rotates relative to the headlight housing 5, it drives the upper end of the lens bracket 1 to rotate from top to bottom relative to the first fine-tuning ball head screw 21 and the fixed ball head screw 23 at the lower end of the lens bracket 1. In this way, the lens 4 can be rotated and adjusted in the up, down, left, and right directions.

[0039] It should be noted that the first rotation axis is along the direction shown by the Z-axis, and the first direction is the direction of the rotation arc around the Z-axis; the second rotation axis is along the direction shown by the Y-axis, and the second direction is the direction of the rotation arc around the Y-axis.

[0040] like Figure 1 As shown, optionally, the automotive headlight lens adjustment structure further includes a second adjustment component 3, and each of the first adjustment components 2 is used to be mounted on the headlight housing 5 via the same second adjustment component 3.

[0041] In this embodiment, based on the adjustment of a single lens 4 driven by the first adjustment component 2, each first adjustment component 2 is mounted on the same second adjustment component 3, so that all lenses 4 can be adjusted together by the second adjustment component 3 to meet the adjustment needs of different occasions.

[0042] like Figure 2-3 As shown in Figures 5-6, optionally, the second adjustment component 3 includes a first sliding bracket 31 and a second sliding bracket 32 ​​disposed opposite to each other. The first sliding bracket 31 and the second sliding bracket 32 ​​are slidably connected to the headlight housing 5. The first fine-tuning ball head screw 21 is connected to the first sliding bracket 31, and the second fine-tuning ball head screw 22 is connected to the second sliding bracket 32.

[0043] When the first sliding bracket 31 slides relative to the headlight housing 5, all the lens brackets 1 rotate around the second fine-tuning ball head screw 22 and the fixed ball head screw 23 in the first direction. When the second sliding bracket 32 ​​slides relative to the headlight housing 5, all the lens brackets 1 rotate around the first fine-tuning ball head screw 21 and the fixed ball head screw 23 in the second direction.

[0044] In this embodiment, the first sliding bracket 31 and the second sliding bracket 32 ​​are arranged along the Y-axis, with the second sliding bracket 32 ​​positioned above the first sliding bracket 31. The distance between the first sliding bracket 31 and the second sliding bracket 32 ​​depends on the distance between the fixing ball head screw 23 and the second fine-tuning ball head screw 22. The first sliding bracket 31 and the second sliding bracket 32 ​​can be irregularly shaped, designed according to the installation position of the lens 4. Figure 1 As shown, the two lenses are positioned one in front of the other, and the first sliding bracket 31 and the second sliding bracket 32 ​​can be provided with stepped mounting surfaces along the front-back direction.

[0045] Here, the fixed ball head screws 23 of each of the first adjustment components 2 are fixedly connected to the headlight housing 5, and the first fine-tuning ball head screws 21 are installed on the first sliding bracket 31. When the first fine-tuning ball head screw 21 is located to the right of the fixed ball head screw 23, and the first sliding bracket 31 slides relative to the headlight housing 5 in the front-back direction, the second fine-tuning ball head screw 22 and the fixed ball head screw 23 of each of the first adjustment components 2 serve as rotation points, and all the lens brackets 1 rotate around the straight line connecting these two points.

[0046] The second fine-tuning ball head screw 22 of each of the first adjustment components 2 is installed on the second sliding bracket 32. When the second fine-tuning ball head screw 22 is located above the fixed ball head screw 23 and the second sliding bracket 32 ​​slides relative to the headlight housing 5 in the front-back direction, the first fine-tuning ball head screw 21 and the fixed ball head screw 23 of each of the first adjustment components 2 serve as rotation points, and all the lens brackets 1 rotate around the straight line connecting the two points.

[0047] like Figure 2-3As shown, optionally, the second adjustment component 3 further includes an adjustment screw 33, one end of which is connected to the first sliding bracket 31 or the second sliding bracket 32. The first sliding bracket 31 or the second sliding bracket 32 ​​is provided with a limiting block 34, and the headlight housing 5 is provided with a limiting groove 51 adapted to the limiting block 34. The limiting groove 51 extends along the length direction of the adjustment screw 33, and the limiting block 34 is placed in the limiting groove 51. When the adjustment screw 33 rotates, the first sliding bracket 31 or the second sliding bracket 32 ​​is used to slide relative to the headlight housing 5 through the limiting block 34 and the limiting groove 51.

[0048] In this embodiment, the adjusting screw 33 is arranged along the X-axis direction, and one screw can be provided on each of the first sliding bracket 31 and the second sliding bracket 32, respectively, for adjusting the first sliding bracket 31 and the second sliding bracket 32.

[0049] Taking the adjustment screw 33 on the first sliding bracket 31 as an example, the adjustment screw 33 is threadedly connected to the first sliding bracket 31. The first limiting groove can be a U-shaped groove that extends along the X-axis. When the adjustment screw 33 is rotated, the first sliding bracket 31 tends to rotate relative to the headlight housing 5. Due to the limiting effect of the limiting block 34 of the first sliding bracket 31 and the limiting groove 51 on the headlight housing 5, the first sliding bracket 31 cannot rotate relative to the headlight housing 5 and can only move along the X-axis.

[0050] Optionally, one end of the adjusting screw 33 away from the first sliding bracket 31 or the second sliding bracket 32 ​​is used to extend out of the headlight housing 5.

[0051] In this embodiment, the front end of the adjusting screw 33 is connected to the first sliding bracket 31 or the second sliding bracket 32, and the rear end of the adjusting screw 33 can extend out from the headlight housing 5, so as to facilitate rotating the adjusting screw 33 outside the headlight to adjust the position of the lens 4.

[0052] The rotation drive of the adjusting screw 33 can be operated manually or by a rotation drive mechanism.

[0053] like Figure 3 , 5 As shown, optionally, the first fine-tuning ball head screw 21 is provided with a limiting piece 211 along the circumferential direction, and the first sliding bracket 31 is provided with a baffle 311. The baffle 311 is used to abut against the limiting piece 211, and the first fine-tuning ball head screw 21 is used to limit the adjustment stroke of the lens 4 through the limiting piece 211 and the baffle 311.

[0054] In this embodiment, the limiting piece 211 can be hexagonal, circular, square, etc. The front end of the first sliding bracket 31 extends forward to form an L-shaped baffle 311. The L-shaped baffle includes a first connecting piece arranged along the X-axis and a second connecting piece arranged along the Y-axis. The limiting piece 211 is located between the second connecting piece and the front end of the first sliding bracket 31, and at a preset distance from both. This preset distance is the length by which the first fine-tuning ball screw 21 rotates in and out along the X-axis. The preset distance can be 2-2.5mm.

[0055] When the first fine-tuning ball screw 21 is rotated until the limiting piece 211 abuts against the stop piece 311, the rotation stops. This prevents the first fine-tuning ball screw 21 from being rotated too much, causing the lens 4 to be completely misaligned and resulting in adjustment failure, thus achieving control over the adjustment stroke of the lens 4.

[0056] Of course, in some other embodiments, the adjustment stroke of the second fine-tuning ball screw 22 can also be limited in the same way.

[0057] like Figure 1 , 2 As shown in Figure 4, another embodiment of the present invention also provides an automotive headlight, including a lens 4, a headlight housing 5, and the aforementioned automotive headlight lens adjustment structure. The lens 4 is mounted on the headlight housing 5 via the automotive headlight lens adjustment structure. The advantages of this embodiment compared to the prior art are the same as those of the aforementioned automotive headlight lens adjustment structure, and will not be repeated here.

[0058] Optionally, the car headlight also includes a plug 6, and the headlight housing 5 has an adjustment hole at a position corresponding to the fine-tuning ball screw of the car headlight lens adjustment structure, and the plug 6 is installed at the adjustment hole.

[0059] In this embodiment, the adjustment hole is located at the rear end of the headlight housing 5. When it is necessary to adjust a certain lens 4, the corresponding plug 6 is unscrewed, and a tool is inserted into the headlight housing 5 through the adjustment hole to rotate the fine-tuning ball head screw, so as to achieve fine-tuning of the position of the lens 4 outside the lamp, avoiding the impact on the production cycle due to the inability to adjust outside the production line.

[0060] Another embodiment of the present invention provides an automobile, including the aforementioned automobile headlight. The advantages of this embodiment compared to the prior art are the same as those of the aforementioned automobile headlight, and will not be repeated here.

[0061] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
