Description

Technical Field

[0001] This utility model belongs to the field of fixture technology, specifically relating to a light metering fixture for a vehicle headlight module. Background Technology

[0002] Light measurement of automotive headlight modules is a crucial testing step to ensure the safety and performance of automotive lighting systems. By measuring aspects such as brightness, beam distribution, color temperature, and uniformity, it is possible to ensure that the headlights can provide adequate visibility under various conditions and avoid interfering with other drivers. This requires fixing the headlight module in a fixture for light measurement.

[0003] The existing light metering fixtures for automotive headlight modules lack accurate standard positioning and only achieve fixation. They cannot achieve the same six degrees of freedom as the entire headlight. Due to the deviation between the fixture and the actual installation position of the headlight module, there is an error in the headlight testing and actual use. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a light metering fixture for automotive headlight modules. The specific technical solution is as follows:

[0005] A light metering fixture for a vehicle headlight module includes a large plate and a quick clamp mounted on the large plate. A bracket for increasing height is installed between the large plate and the quick clamp. A central hole is formed in the middle of the large plate. A first limiting hole and three second limiting holes are formed on the surface of the large plate. A square limiting post is fixed in the first limiting hole by bolts. A circular limiting post, a first circular limiting post, and a second circular limiting post are respectively fixed in the three second limiting holes by bolts. The square limiting post, the circular limiting post, the first circular limiting post, and the second circular limiting post are used to support the vehicle headlight module. A pressure adjusting component is installed at the clamping end of the quick clamp, and a rubber pressure head for clamping the vehicle headlight module is installed at the telescopic end of the pressure adjusting component.

[0006] Preferably, the upper end of the square limiting post is inserted into the square hole of the headlight module, and the upper end of the circular limiting post is inserted into the circular hole of the headlight module. The upper ends of the first circular limiting post and the second circular limiting post are in contact with the lower surface of the headlight module.

[0007] Preferably, the pressure regulating component includes an externally threaded sleeve installed in a hole in the clamping end of the quick clamp. Both ends of the externally threaded sleeve are screwed with nuts. A washer is also sleeved on the outside of the externally threaded sleeve, and the washer is located between the nuts and the clamping end of the quick clamp. An adjusting rod is movably installed inside the externally threaded sleeve. A retaining ring is fixed inside the externally threaded sleeve on the adjusting rod. A spring is installed between the retaining ring and the externally threaded sleeve, and the spring is sleeved on the outside of the adjusting rod.

[0008] Preferably, the lower end of the adjusting rod is fixed to the rubber pressure head, and the lower part of the rubber pressure head is provided with a buffer cavity for deformation, and a buffer plate is fixed inside the buffer cavity.

[0009] Preferably, a first limiting hole and three second limiting holes are arranged in a rectangular pattern, and a circular limiting post is installed in a second limiting hole diagonally opposite to the first limiting hole by bolts. The first circular limiting post and the second circular limiting post are installed in two other second limiting holes by bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The headlight module is supported by square, circular, first, and second circular limiting posts mounted on the surface of the large plate. After support, the headlight module is clamped by quick clamps. The square, circular, first, and second circular limiting posts work together, and the quick clamps restrict six degrees of freedom of the headlight module, ensuring a tight fit between the large plate and the headlight module. This facilitates the simulation of the six degrees of freedom of the actual headlight module installation for light metering and light distribution, solving the problem of inaccurate standard positioning of tooling fixtures in existing technologies. The light metering fixture is designed from the installation angle of the headlight module, restoring the installation positioning relationship of the headlight module and improving the rationality of the light distribution angle and positioning. The rationality of the light distribution angle and positioning logic is achieved without adding too many positioning points. The pressure regulating component installed at the clamping end of the quick clamp, and the rubber pressure head installed at the telescopic end of the pressure regulating component, facilitate the adjustment of the clamping position of the rubber pressure head, making it easy for the rubber pressure head to clamp and fix headlight modules of different thicknesses.

[0012] 2. The upper end of the square limiting post is inserted into the square hole of the headlight module, and the upper end of the round limiting post is inserted into the round hole of the headlight module. The upper ends of the first round limiting post and the second round limiting post are in contact with the lower surface of the headlight module. This allows the square limiting post, the round limiting post, the first round limiting post and the second round limiting post to restore the installation positioning relationship of the headlight module and improve the light distribution angle and positioning rationality.

[0019] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-5 This embodiment provides the following technical solution: a light metering fixture for a vehicle headlight module, including a large plate 1 and a quick clamp 3 set on the large plate 1. A bracket 2 for increasing height is installed between the large plate 1 and the quick clamp 3. A central hole 11 is opened in the middle of the large plate 1. A first limiting hole 4 and three second limiting holes 5 are opened on the surface of the large plate 1. A square limiting post 6 is fixed in the first limiting hole 4 by bolts. A circular limiting post 7, a first circular limiting post 8 and a second circular limiting post 9 are respectively fixed in the three second limiting holes 5 by bolts. The square limiting post 6, the circular limiting post 7, the first circular limiting post 8 and the second circular limiting post 9 are used to support the vehicle headlight module 10. A pressure adjusting component 12 is installed at the clamping end of the quick clamp 3. A rubber pressure head 13 for clamping the vehicle headlight module 10 is installed at the telescopic end of the pressure adjusting component 12.

[0021] In this embodiment, the headlight module 10 is supported by square limiting posts 6, circular limiting posts 7, first circular limiting posts 8, and second circular limiting posts 9 mounted on the surface of the large plate 1. After being supported, the headlight module 10 is clamped by quick clamps 3. The square limiting posts 6, circular limiting posts 7, first circular limiting posts 8, and second circular limiting posts 9, together with the quick clamps 3, restrict six degrees of freedom of the headlight module 10. This ensures a tight fit between the large plate 1 and the headlight module 10, facilitating the simulation of the six degrees of freedom of the actual installation of the headlight module 10 for light measurement and matching. The light metering fixture solves the problem of inaccurate standard positioning of tooling fixtures in the existing technology. It is designed from the installation angle of the car lamp module 10 to restore the installation positioning relationship of the car lamp module 10, improve the rationality of the light distribution angle and positioning, and achieve the rationality of the light distribution angle and positioning logic without adding too many positioning points. The pressure adjusting component 12 installed at the clamping end of the quick clamp 3, and the rubber pressure head 13 installed at the telescopic end of the pressure adjusting component 12, make it easy for the pressure adjusting component 12 to adjust the clamping position of the rubber pressure head 13, so that the rubber pressure head 13 can clamp and fix the car lamp module 10 of different thicknesses.

[0022] In this embodiment, the upper end of the square limiting post 6 is inserted into the square hole of the headlight module 10, the upper end of the round limiting post 7 is inserted into the round hole of the headlight module 10, and the upper ends of the first round limiting post 8 and the second round limiting post 9 are in contact with the lower surface of the headlight module 10.

[0023] In this embodiment, the upper end of the square limiting post 6 is inserted into the square hole of the headlight module 10, and the upper end of the circular limiting post 7 is inserted into the circular hole of the headlight module 10. The upper ends of the first circular limiting post 8 and the second circular limiting post 9 are in contact with the lower surface of the headlight module 10, so that the square limiting post 6, the circular limiting post 7, the first circular limiting post 8 and the second circular limiting post 9 can restore the installation and positioning relationship of the headlight module 10, and improve the light distribution angle and positioning rationality.

[0024] In this embodiment, the pressure regulating component 12 includes an externally threaded sleeve 121 installed in a hole in the clamping end of the quick clamp 3. Both ends of the externally threaded sleeve 121 are screwed with nuts 122. A washer 123 is also sleeved on the outside of the externally threaded sleeve 121, and the washer 123 is located between the nuts 122 and the clamping end of the quick clamp 3. An adjusting rod 124 is movably installed inside the externally threaded sleeve 121. A retaining ring 125 is fixed inside the adjusting rod 124. A spring 126 is installed between the retaining ring 125 and the externally threaded sleeve 121, and the spring 126 is sleeved on the outside of the adjusting rod 124.

[0025] In this embodiment, the pressure regulating component 12, composed of an external threaded sleeve 121, a nut 122, a washer 123, an adjusting rod 124, a retaining ring 125, and a spring 126, is used. The nut 122 screwed onto both ends of the external threaded sleeve 121, and the washer 123 placed between the nut 122 and the clamping end of the quick clamp 3, facilitate the fixing of the external threaded sleeve 121 to the clamping end of the quick clamp 3 by the nut 122 screwed onto both ends. This facilitates the adjustment of the position of the nut 122 at both ends of the external threaded sleeve 121, thereby achieving the purpose of adjusting the position of the rubber pressure head 13. The adjusting rod 124, which is movably installed on the external threaded sleeve 121 through the retaining ring 125 and the spring 126, facilitates the compression of the rubber pressure head 13 installed at the lower end of the adjusting rod 124 by the retaining ring 125 and the spring 126 after it is squeezed. This helps the rubber pressure head 13 maintain its elasticity when compressing the vehicle light module 10.

[0026] In this embodiment, the lower end of the adjusting rod 124 is fixed to the rubber pressure head 13, and the lower part of the rubber pressure head 13 is provided with a buffer cavity 14 for deformation, and a buffer plate 15 is fixed inside the buffer cavity 14.

[0027] In this embodiment, the buffer cavity 14 provided at the lower end of the rubber pressure head 13 and the buffer plate 15 fixed in the buffer cavity 14 enable the lower surface of the rubber pressure head 13 to undergo elastic deformation when it comes into contact with the vehicle light module 10, thereby preventing excessive displacement of the rubber pressure head 13 from damaging the vehicle light module 10.

[0028] In this embodiment, a first limiting hole 4 and three second limiting holes 5 are arranged in a rectangular pattern. A circular limiting post 7 is installed in the second limiting hole 5 diagonally opposite to the first limiting hole 4 by bolts. A first circular limiting post 8 and a second circular limiting post 9 are installed in the other two second limiting holes 5 by bolts.
