Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology and relates to a simple light distribution fixture with an adjustment mechanism. Background Technology

[0002] In the field of automotive lighting manufacturing and testing, light distribution fixtures are key equipment, undertaking the important tasks of fixing and positioning vehicle lights or vehicle light modules (such as high and low beam lenses, reflectors, etc.), and assisting in light pattern adjustment and light distribution testing.

[0003] With advancements in automotive lighting technology, modern car lights often employ multi-lens module systems (typically containing 2-4 lenses). To achieve a light pattern distribution that complies with safety regulations (such as cutoff lines, illumination width, and distance), precise adjustment of the relative angles of each module and the spatial angles of the entire system is required.

[0004] However, most current beam distribution fixtures for high and low beam modules are functionally limited, only able to fix the luminaire and lacking angle adjustment capabilities. In luminaire beam distribution testing, the aiming stage can only be compensated for by adjusting the test platform, which significantly reduces testing efficiency. When the luminaire is a multi-lens module system, because existing beam distribution fixtures cannot achieve angle adjustment, two or more adjustment brackets must be installed inside the luminaire to adjust the angle of each module, making the operation cumbersome. A few beam distribution fixtures with adjustment capabilities can achieve angle adjustment, but they require lifting and rotating mechanisms, resulting in a complex overall structure and high cost. Utility Model Content

[0005] The purpose of this invention is to provide a simple light distribution fixture with an adjustment mechanism to solve the problems mentioned in the background art.

[0006] The objective of this utility model is achieved through the following technical solution: A simple light distribution fixture with an adjustment mechanism includes a base, on which a vertical support is fixedly mounted. The vertical support has a first opening for a lamp under test to pass through. The lamp under test is locked onto a product bracket. Several adjustment mechanisms are provided between the vertical support and the product bracket. Each adjustment mechanism includes an adjustment rod, one end of which is detachably and fixedly connected to the vertical support, and the other end of which is threadedly connected to a fisheye bearing. A spherical ball is movably disposed at the fisheye of the fisheye bearing. A slot is provided on the product bracket, and one end of the fisheye bearing and the spherical ball are disposed in the slot and positioned on the product bracket using a connector. The spherical ball is made of steel.

[0007] As a further improvement of one embodiment of the present invention, the vertical support is provided with a through hole for inserting one end of the adjusting rod, and the adjusting rod is locked to the vertical support by a first locking nut.

[0008] As a further improvement of one embodiment of this utility model, the central boss of the adjusting rod is an abutment part, and the threads on the adjusting rod on both sides of the abutment part are positive threads and negative threads, respectively; the first locking nut is connected to the positive thread of the adjusting rod, and the negative thread of the adjusting rod is connected to the second locking nut, which is used to adjust the fisheye bearing in the locking position of the adjusting rod.

[0009] As a further improvement of one embodiment of the present invention, the diameter of the spherical bead is larger than the width of the fisheye bearing, so that both ends of the spherical bead are exposed outside the fisheye bearing, thereby increasing the range of motion between the fisheye bearing and the spherical bead.

[0010] As a further improvement of one embodiment of the present invention, the spherical bead is provided with a positioning hole, the positioning hole passing through the center of the spherical bead; the product bracket is provided with a side hole communicating with the slot; the connector is inserted into the side hole and the positioning hole to position the spherical bead in the slot.

[0011] As a further improvement of one embodiment of this utility model, the connector is a pin or a plug screw. The side hole consists of two sections and is distributed on both sides of the slot; when the connector is a plug screw, the inner section of the side hole is provided with an internal thread structure corresponding to the plug screw.

[0012] As a further improvement of one embodiment of the present utility model, the product bracket has a square structure, and the middle part of the product bracket has a second opening for inserting one end of the lamp to be tested; four slots are provided on the product bracket surrounding the lamp to be tested, and the slots are distributed at the four corners of the product bracket.

[0013] As a further improvement of one embodiment of the present utility model, a plurality of fixing ears are symmetrically arranged between the base and the vertical support, and the fixing ears are respectively locked to the base and the vertical support by bolt assemblies.

[0014] The above technical solution has the following advantages: by adjusting the position between the pull rod and the fisheye bearing and the position between the pull rod and the vertical support, the pitch angle, horizontal angle and forward and backward translation of the lamp under test can be adjusted. And by relying on the movable connection between the fisheye bearing and the ball bearing, the deflection angle of the lamp under test can be finely adjusted. The angle adjustment of the lamp under test can be achieved efficiently and conveniently. Attached Figure Description

Example

[0027] See Figures 1-6 As shown, a simple light distribution fixture with an adjustment mechanism is designed to provide an efficient, convenient, and structurally simple solution for light distribution testing of automotive lamps.

[0028] This simple light distribution fixture mainly consists of a base 1, a vertical support 2, a lamp under test 3, a product bracket 5, and adjustment mechanisms 6, 7, and 8. The base 1 provides a stable support foundation for the entire fixture, ensuring that it will not shake during testing, thus guaranteeing the accuracy of the test results. The vertical support 2 is fixedly mounted on the base 1 and has a first opening 21 for the lamp under test 3 to pass through, facilitating the installation and positioning of the lamp under test 3.

[0029] The lamp under test 3 is locked onto its inherent product bracket 5. The product bracket 5 acts as a bridge connecting the lamp under test 3 to the adjustment mechanisms 6, 7, and 8, transmitting the adjustment force. The adjustment mechanisms 6, 7, and 8 have the same structure; for ease of description, adjustment mechanism 6 will be used as an example. Adjustment mechanism 6 includes an adjustment rod 61. One end of the adjustment rod 61 is detachably and fixedly connected to the vertical bracket 2, and the other end is threadedly connected to the fisheye bearing 63. This threaded connection allows for flexible adjustment of the relative position between the adjustment rod 61 and the fisheye bearing 63. A spherical ball 65 is movably disposed at the fisheye of the fisheye bearing 63. The product bracket 5 has a slot 51, and one end of the fisheye bearing 63 and the spherical ball 65 are disposed within the slot 51 and positioned on the product bracket 5 by a connector 66. The spherical ball 65 is made of steel ball material, possessing good wear resistance and stability.

[0030] In practical use, by adjusting the position between the pull rod 61 and the fisheye bearing 63, and by adjusting the position between the pull rod 61 and the vertical support 2, the pitch angle, horizontal angle, and forward and backward translation of the lamp under test 3 can be adjusted. Furthermore, relying on the movable connection between the fisheye bearing 63 and the spherical ball 65, the deflection angle of the lamp under test 3 can also be finely adjusted, thereby meeting the light distribution testing requirements of different types of automotive lamps.

[0031] Specifically, the vertical bracket 2 is provided with a through hole for inserting one end of the adjusting rod 61. The size of this through hole is adapted to the outer diameter of the adjusting rod 61, ensuring that the adjusting rod 61 can be smoothly inserted without significant shaking or displacement during the insertion process, providing a stable foundation for subsequent adjustment operations. The adjusting rod 61 and the vertical bracket 2 are locked together by a first locking nut 62.

[0032] Combination Figure 5 As shown, the adjusting rod 61 has a boss in the middle as a contact part 611, which plays a key positioning role during adjustment. The adjusting rods 61 on both sides of the contact part 61 are respectively machined with positive and negative threads. The first locking nut 62 is tightly connected to the positive thread of the adjusting rod 61. By rotating the first locking nut 62, it can be moved along the positive thread, thereby reliably locking the adjusting rod 61 to the vertical support 2 and preventing the adjusting rod 61 from loosening during testing.

[0033] The reverse thread of the adjusting rod 61 is connected to the second locking nut 64. The main function of the second locking nut 64 is to adjust the locking position of the fisheye bearing 63 on the adjusting rod 61. By rotating the second locking nut 64, it moves on the reverse thread, thereby changing the relative position of the fisheye bearing 63 and the adjusting rod 61, achieving precise adjustment of the position of the fisheye bearing 63 to meet the diverse needs of angle adjustment during light distribution testing of different lamps.

[0034] In this embodiment, the diameter of the spherical bead 65 is designed to be larger than the width of the fisheye bearing 63. This size design allows both ends of the spherical bead 65 to be exposed outside the fisheye bearing 63, thereby effectively increasing the range of motion between the fisheye bearing 63 and the spherical bead 65. When fine-tuning the deflection angle of the lamp under test, the larger range of motion allows for a more flexible and precise adjustment process, meeting the needs of different lamps for fine angle adjustments during light distribution testing.

[0035] Furthermore, the spherical bead 65 is provided with a positioning hole 651, which precisely passes through the center of the spherical bead 65. This design ensures the uniformity of the force on the spherical bead 65 after positioning, and avoids the spherical bead 65 from shifting or being damaged during subsequent use due to uneven force.

[0036] The product bracket 5 has a side hole 52 communicating with the slot 51. During assembly, after the spherical bead 65 is placed into the slot 51 of the product bracket 5, the connector 66 is inserted into the side hole 52 and the positioning hole 651. Through this simple and effective connection method, the spherical bead 65 can be reliably positioned in the slot 51. This structure not only facilitates assembly but also ensures the stability of the spherical bead 65 on the product bracket 5, ensuring that the adjustment function between the spherical bead 65 and the fisheye bearing 63 functions normally during the light distribution test of the lamp.

[0037] In this embodiment, the connector 66 has two feasible equivalent implementations: a pin or a screw. The side hole 52 on the product bracket 5 consists of two sections, respectively distributed on both sides of the slot 51. When a pin is selected as the connector 66, the pin is directly inserted into the two side holes 52 and the positioning hole 651 of the spherical bead 65 to achieve positioning. If a screw is selected as the connector 66, to ensure a stable connection, the inner side hole is provided with an internal thread structure corresponding to the screw. The screw is screwed into the internal thread, passes through the positioning hole 651, and thus reliably positions the spherical bead 65 in the slot 51.

[0038] In this embodiment, the product bracket 5 adopts a square structure, which is simple and stable, and easy to process, manufacture, and install. The middle of the product bracket 5 is provided with a second opening 53 for inserting one end of the lamp 3 to be tested. The size of the second opening 53 is adapted to the outer diameter of the lamp 3 to be tested. The product bracket 5 and the lamp 3 to be tested are locked together with bolts, so that there will be no obvious shaking between them, providing a reliable foundation for subsequent adjustment and testing.

[0039] Four slots 51 are evenly arranged on the product bracket 5 surrounding the lamp under test 3, and these four slots 51 are respectively distributed at the four corners of the product bracket 5. This design allows the adjustment mechanism to be selectively installed at the four corners of the product bracket 5 as needed, ensuring the uniformity and stability of the adjustment when adjusting the angle of the lamp under test 3, and avoiding situations where the lamp under test 3 is tilted or subjected to uneven force due to uneven adjustment.

[0040] A number of fixing ears 4 are symmetrically arranged between the base 1 and the vertical support 2. The number of fixing ears 4 can be determined according to actual needs; four are used in this embodiment. The fixing ears 4 are provided with corresponding mounting holes and are locked to the base 1 and the vertical support 2 respectively by bolt assemblies. This connection method is not only simple in structure but also firmly connected, ensuring that the vertical support 2 is stably fixed on the base 1, providing reliable support for the entire light distribution fixture.

[0041] The simplified light distribution fixture provided by this utility model has unique advantages in adjusting the angle and position of the lamp under test. By adjusting the positional relationship between the adjusting rod and the fisheye bearing in each adjusting mechanism, as well as the position between the adjusting rod and the vertical support, the lamp under test can be flexibly adjusted in multiple dimensions.

[0042] Specifically, combined Figure 4 As shown, when the product under test is being aimed and adjusted, the strokes of adjustment mechanisms 6 and 8 are fixed, and the extension and retraction of the adjustment rod of adjustment mechanism 7 can achieve pitch angle adjustment with Line 1 as the reference axis; when the product under test is being aimed and adjusted, the strokes of adjustment mechanisms 6 and 7 are fixed, and the extension and retraction of the adjustment rod of adjustment mechanism 8 can achieve horizontal angle adjustment with Line 2 as the reference axis; when the product under test is being aimed and adjusted, adjustment mechanisms 6, 7, and 8 can be adjusted by the same extension and retraction amount at the same time to achieve translation adjustment in the forward and backward directions.

[0043] Furthermore, the deflection angle of the lamp under test can be finely adjusted by the movable connection between the fisheye bearing and the spherical ball. The spherical ball rotates flexibly at the fisheye of the fisheye bearing, allowing the lamp under test to deflect within a small range, further improving the adjustment accuracy. This adjustment method is not only simple to operate, but also has a wide adjustment range and high precision, meeting the diverse angle and position requirements of different types of automotive lamps during photometric testing, effectively improving the efficiency and accuracy of photometric testing.
