Description

Technical Field

[0001] The utility model relates to the technical field of a test bench for a vehicle-mounted head-up display device, in particular to a test bench for a vehicle-mounted head-up display device. Background Art

[0002] As we all know, HUD modules are currently widely installed in cars for augmented reality and are widely used in smart driving cars. As part of the driving assistance module, the car's speed, mileage, ACC, LDW and other driving assistance information can be projected onto the glass, making it easier for drivers to understand the vehicle's driving status information while giving the driver an immersive driving experience. Before the HUD module is installed in the car, it must undergo rigorous preliminary R&D testing of various indicators such as chromaticity, brightness, ghosting, distortion, field of view, binocular parallax, MTF, etc. The test principle is to use a glass positioning fixture (with adjustable inclination) to simulate the car's front windshield, light up the HUD module, and use different optical test pictures to test different optical test items, thereby verifying various indicators of the HUD module.

[0003] The existing test bench for vehicle-mounted head-up display devices is not compatible with front windshields of different widths and different car models, and does not have the automatic glass centering effect, which makes it inconvenient to use. Therefore, we propose a test bench for vehicle-mounted head-up display devices to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-3The utility model provides a test bench for a vehicle-mounted head-up display device, including a HUD optical test bench 1. The HUD optical test bench 1 is provided with several bolt mounting holes, so that the HUD optical test bench 1 is convenient for fixing its other components. Several glass tilt adjustment devices 2 are provided at the rear of the top of the HUD optical test bench 1. A glass centering adjustment device 3 is provided at the middle of the top of the HUD optical test bench 1. The glass centering adjustment device 3 includes two sliding adjustment seats, each of which is provided with a sliding block, and each sliding block is slidably matched with the sliding adjustment seat. A rotating motor pull block is provided in the middle of the two sliding adjustment seats, and the left and right ends of the rotating motor pull block are respectively connected to each sliding block, so that the glass centering adjustment device 3 is convenient for positioning the glass. A positioning support seat 4 is provided at the top front of the HUD optical test bench 1. A HUD calibration device 5 is provided at the front end of the HUD optical test bench 1.
