Description

Technical Field

[0001] This utility model relates to the field of headlamp detection technology, specifically a positioning and adjustment device for headlamp detection. Background Technology

[0002] A headlamp is a head-mounted lighting tool primarily used to free up the hands and provide convenient illumination. It is widely used in various scenarios, including but not limited to outdoor activities, industrial applications, medical fields, emergencies, military uses, sports and fitness, and adventure activities. After production, headlamps require brightness testing.

[0003] In existing technologies, after headlamps are manufactured, quality inspectors usually turn on the headlamp switch to observe whether the headlamp lights up normally in order to determine whether the brightness of the headlamp is up to standard. This method can only roughly determine whether the headlamp can light up normally and whether there are obvious defects in brightness. It cannot effectively detect the brightness of the headlamp at different distances. Therefore, we need to propose a positioning and adjustment device for headlamp testing. Utility Model Content

[0020] 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.

[0021] Please see Figures 1-4 This utility model provides a positioning and adjustment device for headlamp detection, including a base plate 1. A light detection target plate 2 is fixedly installed at one end of the base plate 1. A movable plate 3 is slidably connected to the top of the base plate 1. A sliding connection assembly is provided between the movable plate 3 and the base plate 1. The bottom of the movable plate 3 is slidably connected to the top of the base plate 1 through the sliding connection assembly. The sliding connection assembly includes limiting plates 17 fixedly installed on both sides of the bottom of the movable plate 3. A sliding rod 18 is fixedly installed on the inner side of each of the two sets of limiting plates 17. A sliding groove 19 adapted to the sliding rod 18 is opened on both sides of the base plate 1. The surface of the sliding rod 18 is slidably connected to the inner wall of the sliding groove 19.

[0022] By using the sliding connection assembly, the movable plate 3 can be slidably mounted on the top of the base plate 1. When the movable plate 3 moves, it causes the slide rod 18 to slide within the cavity of the slide groove 19. The combined use of the slide rod 18, the slide groove 19, and the limiting plate 17 also limits the movable plate 3, preventing it from slipping off the surface of the base plate 1 during movement. By adjusting the movable plate 3, the user can adjust the distance between the headlamp and the light detection target plate 2, allowing the headlamp's lighting effect to be detected at different distances.

[0023] Preferably, a positioning component for fixing the headlamp to be tested is fixedly installed on the top of the movable plate 3. The positioning component includes a support base 9 fixedly installed on the top of the movable plate 3, a lower positioning frame 10 fixedly installed on the top of the support base 9, an upper positioning frame 11 provided on the top of the lower positioning frame 10, and an elastic connection component provided between the upper positioning frame 11 and the movable plate 3. The upper positioning frame 11 is movably connected to the movable plate 3 through the elastic connection component. The elastic connection component includes two sets of connecting seats 12 fixedly installed on the top of the movable plate 3. Two sets of connecting seats 12 are provided, and the two sets of connecting seats 12 are respectively provided on both sides of the support base 9. Connecting plates 13 are fixedly installed on both sides of the upper positioning frame 11. A tension spring 14 is fixedly installed on the bottom of the connecting plate 13, and the bottom end of the tension spring 14 is fixedly connected to the top of the connecting seat 12.

[0024] By setting the positioning components, the headlamp can be installed and fixed on the top of the movable plate 3. Specifically, the user can pull the upper positioning frame 11 upward and place the headlamp between the upper positioning frame 11 and the lower positioning frame 10. When the upper positioning frame 11 is pulled, the tension spring 14 will be pulled through the connecting plate 13. After the headlamp is placed between the upper positioning frame 11 and the lower positioning frame 10, the user can release the upper positioning frame 11. At this time, the reaction force generated by the tension spring 14 will pull the upper positioning frame 11 downward to press and fix the headlamp on the top of the lower positioning frame 10, thereby achieving the purpose of positioning the headlamp.

[0025] Among them, a guide component for improving the movement stability of the upper positioning seat is also provided between the connecting plate 13 and the connecting seat 12. The guide component includes a guide rod 15 fixedly installed at the bottom of the connecting plate 13, and a guide hole 16 is opened at the top of the connecting seat 12 and at the corresponding position of the guide rod 15. The surface of the guide rod 15 is slidably connected to the inner wall of the guide hole 16.

[0026] By setting the guide component, the stability of the connecting plate 13 movement can be improved, thereby improving the stability of the upper positioning frame 11 movement. When the upper positioning frame 11 moves, it will drive the guide rod 15 to slide in the inner cavity of the guide hole 16 through the connecting plate 13.

[0027] It is worth noting that the top of the movable plate 3 is also equipped with a movable component for adjusting the distance between the headlamp to be tested and the light detection target plate 2. The movable component includes a drive motor 4 fixedly installed on the top of the movable plate 3. A gear 5 is fixedly installed on the output shaft of the drive motor 4. A toothed groove 6 is opened on the top of the base plate 1 at the corresponding position of the gear 5. The bottom of the gear 5 passes through the movable plate 3 and extends to the bottom of the movable plate 3 to mesh with the toothed groove 6.

[0028] By setting up the moving component, the headlamp can be moved to adjust the distance between it and the light detection target plate 2. Specifically, the output shaft of the drive motor 4 will drive the gear 5 to rotate. Since the bottom of the gear 5 meshes with the tooth groove 6, when the gear 5 rotates, it will drive the moving plate 3 to slide on the top of the base plate 1, thereby adjusting the detection position of the headlamp.

[0029] Furthermore, a rotating groove 7 is provided on the surface of the movable plate 3 at the corresponding position of the gear 5. The surface of the gear 5 is rotatably connected to the inner cavity of the rotating groove 7. A support frame 8 is fixedly installed on the top of the movable plate 3 below the drive motor 4. The bottom of the drive motor 4 is fixedly connected to the top of the support frame 8.

[0030] The rotating slot 7 provides space for the gear 5 to rotate, preventing the moving plate 3 from obstructing the normal rotation of the gear 5. The support frame 8 allows the drive motor 4 to be mounted and fixed on the top of the moving plate 3.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
