Description

Technical Field

[0001] This utility model belongs to the field of head-up display technology and relates to a semi-universal simple HUD verification stand. Background Technology

[0002] As an important display device in the automotive field, HUD (Head-Up Display) requires bench demonstrations or on-vehicle verification after the prototype is assembled in the early stages of development to test its structural and optical design effects. This is a key step in the HUD development process.

[0003] In existing technologies, verification of HUD prototypes typically requires either designing a dedicated demonstration stand for a specific HUD model or conducting vehicle-mounted verification. When using a dedicated stand design, all components, including the base and support, must be redesigned based on the structural parameters, installation dimensions, and windshield characteristics of each HUD model. This involves not only designing a large number of parts but also individually prototyping and manufacturing each designed part. Vehicle-mounted verification, on the other hand, requires waiting for the vehicle to be assembled, and any adjustments to the HUD's structure during verification must be coordinated with the overall vehicle workflow, making the process cumbersome.

[0004] The above verification methods have obvious drawbacks: on the one hand, the design and prototyping of dedicated test benches, as well as the waiting and coordination for vehicle-mounted verification, all consume a lot of time, resulting in a significant extension of the overall HUD development cycle; on the other hand, the design, prototyping, and supporting costs of dedicated parts during vehicle-mounted verification are high, which greatly increases the economic cost of HUD development and is not conducive to the rapid iteration and cost control of HUD products. Utility Model Content

The light reflected from the prototype 5 is displayed through the windshield 4 to simulate the light path of the vehicle.

[0027] Furthermore, the first bracket 2 has an integrally formed extension block 201 in the middle of its inner side, and the extension block 201 has an adjustment hole 202.

The countersunk screw holes 401 are used to be screwed into the front screw hole 1001 and the rear screw hole 1101 respectively.

[0030] By simulating the actual optical path environment of a vehicle, the optical performance and structural adaptability of the HUD prototype can be quickly tested. The prototype 5 (HUD) is installed on the universal base 1. When it is working, the display light emitted by it will be projected onto the windshield 4 according to the preset optical path. The optical characteristics (such as transmittance and reflectivity) and installation angle of the windshield 4 are matched with the windshield parameters of the target vehicle model, which can accurately reproduce the actual display effect of the HUD on the vehicle. By observing the display image on the windshield 4 (such as sharpness, distortion rate, and display position deviation), it can be directly determined whether the optical design of the prototype 5 meets the standards.

[0031] By testing the stability of the connection between the prototype 5 and the first bracket 2 and the second bracket 3, and the assembly of the windshield 4 with the first front arm 6, the first rear arm 7, the second front arm 8 and the second rear arm 9, including the use of the first positioning hole 203 to engage with the first front positioning pin 601 and the first rear positioning pin 701 to ensure the assembly accuracy of the first front positioning pin 601 and the first rear positioning pin 701, and the use of the second positioning hole 302 to engage with the second front positioning pin 801 and the second rear positioning pin 901 to ensure the assembly accuracy of the second front positioning pin 801 and the second rear positioning pin 901, the structural adaptability of the HUD can be verified, and the core performance verification can be completed without waiting for the whole vehicle assembly.

[0032] Compared to existing technologies that require designing a dedicated test bench for each HUD or waiting for vehicle assembly before verification, this HUD verification test bench utilizes a customized combination of universal components and the first front arm 6, first rear arm 7, second front arm 8, and second rear arm 9. Only four small first front arms 6, first rear arms 7, second front arms 8, and second rear arms 9 need to be designed for different HUD windshield angles and installation positions. This shortens the overall verification preparation cycle, reduces costs, facilitates easy disassembly and replacement, and improves efficiency. By replacing the first front arms 6, first rear arms 7, second front arms 8, and second rear arms 9 with different lengths and tilt angles, it can adapt to various types of vehicle HUD prototypes (such as monocular HUDs and binocular HUDs), as well as windshield angles (12-25 degrees) for different vehicle models, without requiring a redesign of the universal base 1 and the first bracket 2 and second bracket 3.

[0033] The windshield 4 can be customized according to the optical parameters (such as refractive index and coating characteristics) of the target vehicle's windshield. The simulated display effect is ≥95% consistent with the actual vehicle state. It can accurately judge the core performance indicators of HUD such as clarity, distortion, and field of view, avoiding the problem of passing bench verification but failing on the vehicle.

[0034] In summary, this utility model provides a semi-universal simplified HUD verification stand. Depending on the different types of windshields 4 and the prototype 5 to be tested, the structure of the first front arm 6, the first rear arm 7, the second front arm 8, and the second rear arm 9 can be designed each time. The universal base 1, the first bracket 2, and the second bracket 3 are universal components that can be directly adapted, which greatly reduces the time for design, processing, installation, testing, and adjustment of the whole machine, effectively reduces costs, and improves the verification efficiency of HUD.

Other specific embodiments of this utility model that can be conceived by those skilled in the art without creative effort will also fall within the protection scope of this utility model.
