Description

Technical Field

[0001] This utility model relates to the field of vehicle light pattern technology, and in particular to a vehicle light pattern adjustment and detection device. Background Technology

[0002] The headlight pattern adjustment test equipment is a professional device for testing, calibrating and adjusting the light pattern parameters of automotive headlights (especially headlights). Its core function is to ensure that the lighting performance of headlights meets safety standards and design requirements, thereby ensuring driving safety. The headlight pattern adjustment test equipment is used during the testing process.

[0003] However, traditional vehicle headlight pattern adjustment testing equipment still has some problems in use. When testing vehicle headlights, they need to be clamped to ensure that they do not move around during the test. Since the two sides of the vehicle headlights have a certain curvature, the traditional clamping structure is prone to loosening when adjusting the angle of the headlights, which affects the test results. Therefore, a vehicle headlight pattern adjustment testing equipment is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle headlight pattern adjustment and testing device to solve the problem that traditional clamping structures are prone to loosening when adjusting the angle of the headlights after clamping them.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vehicle headlight pattern adjustment detection device, including a detection table and a mounting frame;

[0006] The top of the testing station is equipped with a mounting frame, and the top of the mounting frame is equipped with a CMOS image sensor. The front end of the mounting frame is equipped with a control panel. The top of the testing station is provided with a placement platform, and the placement platform is provided with a clamping structure.

[0007] The clamping structure includes a bidirectional screw, which is installed inside the placement platform. Screw sleeves are provided on the outer sides of both ends of the bidirectional screw. A connecting block is installed on the top of the screw sleeve. A fixing rod is installed on one side of the connecting block. A movable sleeve is installed on the outer side of the fixing rod. A clamping plate is fixed on one side of the movable sleeve.

[0012] Preferably, a first gear is mounted on the outer side of the rotating sleeve, a second gear is mounted on one side of the first gear, and a servo motor is mounted on one end of the second gear.

[0013] Preferably, the rotating sleeve is fitted onto the outside of the fixed column, and the rotating sleeve and the fixed column form a movable connection.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating a clamping structure, when clamping the headlight, the screw sleeve and connecting block work together to move two sets of clamping plates to one side and fit them against the sides of the headlight. When the clamping plates fit, they rotate around the outside of the fixing rod according to the shape of one side of the headlight, achieving an adaptive clamping effect, thus making the clamping effect better and more stable.

This rotation of the rotating sleeve outside the fixed column adjusts the angle of the placement platform, indirectly adjusting the angle of the headlight. This makes it easier to detect different light patterns of the headlight at different angles, thus completing the angle adjustment task. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model embodiment provides a vehicle headlight pattern adjustment detection device, such as... Figure 1 - Figure 5 As shown, a vehicle headlight pattern adjustment testing device includes a testing platform 1 and a mounting bracket 2;

[0025] The top of the testing station 1 is equipped with a mounting frame 2, the top of the mounting frame 2 is equipped with a CMOS image sensor 7, the front of the mounting frame 2 is equipped with a control panel 5, the top of the testing station 1 is equipped with a placement platform 3, and the inside of the placement platform 3 is equipped with a clamping structure 4.

[0026] The clamping structure 4 includes a bidirectional screw 401, which is installed inside the placement platform 3. Screw sleeves 402 are provided on the outer sides of both ends of the bidirectional screw 401. A connecting block 403 is installed at the top of the screw sleeve 402. A fixing rod 406 is installed on one side of the connecting block 403. A movable sleeve 405 is installed on the outer side of the fixing rod 406. A clamping plate 404 is fixed on one side of the movable sleeve 405. The movable sleeve 405 is sleeved on the outer side of the fixing rod 406, forming a movable connection with the fixing rod 406. Two sets of screw sleeves 402 are provided, and the two sets of screw sleeves 402 form a threaded connection with the bidirectional screw 401. Two sets of clamping plates 404 are provided, and the two sets of clamping plates 404 are symmetrically distributed at the top of the placement platform 3.

[0027] In a further preferred embodiment of this utility model, such as Figure 1 - Figure 3As shown: When performing beam pattern detection on the vehicle headlight, the headlight is placed on top of the placement platform 3. After placement, the external power supply starts the drive motor, which drives the bidirectional screw 401 to rotate. During rotation, the bidirectional screw 401, through its cooperation with the screw sleeve 402, drives the two sets of connecting blocks 403 to move towards the center position. When the connecting blocks 403 move, they drive the clamping plate 404 to move to one side and fit against both sides of the headlight. When the clamping plate 404 is in contact, it will rotate the movable sleeve 405 outside the fixed rod 406 according to the shape of one side of the headlight, achieving an adaptive clamping effect, thus making the clamping effect better and more stable.

[0028] An angle adjustment structure 6 is provided at the top of the testing table 1. The angle adjustment structure 6 includes a fixed base 601, which is installed at the top of the testing table 1. A fixed column 602 is installed at the top of the fixed base 601. A rotating sleeve 603 is installed on the outside of the fixed column 602. The top of the rotating sleeve 603 is connected to the bottom of the placement table 3. A first gear 604 is installed on the outside of the rotating sleeve 603. A second gear 605 is installed on one side of the first gear 604. A servo motor 606 is installed at one end of the second gear 605. The rotating sleeve 603 is sleeved on the outside of the fixed column 602, and the rotating sleeve 603 and the fixed column 602 are movably connected.

[0029] In a further preferred embodiment of this utility model, such as Figure 4 - Figure 5 As shown: After clamping is completed, the headlight is connected to the power supply and turned on for illumination. At this time, the use of CMOS image sensor 7 allows the light from the headlight to be focused onto the CCD / CMOS chip through the lens. The photosensitive unit pixels on the chip convert the light signal into an electrical signal. The intensity of the electrical signal of different pixels corresponds to the difference in brightness of the light pattern, thereby detecting the light pattern of the headlight. When detecting different angles of the headlight, the servo motor 606 is started to drive the second gear 605 to rotate. During the rotation, the second gear 605 drives the rotating sleeve 603 to rotate through the meshing between the second gear 604 and the first gear 604. This causes the rotating sleeve 603 to rotate outside the fixed column 602 to adjust the angle of the placement platform 3, indirectly adjusting the angle of the headlight, making it more convenient to detect the light pattern of the headlight at different angles, thus completing the angle adjustment work.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
