Description

Technical Field

[0001] This utility model relates to the technical field of HUD testing equipment, specifically to a HUD high temperature resistance and strong light resistance testing equipment. Background Technology

[0002] A head-up display (HUD), also known as a head-up display device, works by projecting important driving information, such as vehicle status information and real-time intersection views, onto a projection medium, such as a windshield or a specially designed screen, through a designed optical path. This assists driving by preventing drivers from looking down at instrument panels or other driver assistance devices, thus avoiding safety hazards and increasing driving safety.

[0003] In practical applications, cars are frequently parked outdoors, resulting in high interior temperatures; especially in hot summers, interior temperatures can sometimes exceed 70°C. Furthermore, vehicles are exposed to direct sunlight, meaning HUD products often operate under high temperatures and intense light. Therefore, before shipping HUD products, their high-temperature and high-light resistance must be tested to ensure continued operation under these conditions. Current technology lacks equipment capable of simultaneously testing these properties, typically requiring multiple devices for testing. This necessitates repeated product transfers and clamping, leading to low testing efficiency and impacting overall HUD production efficiency. Utility Model Content

[0004] To address some or all of the problems existing in the prior art, this utility model provides a HUD high temperature and strong light resistance testing device, including a machine base and a controller. The machine base is equipped with a baking oven, and the baking oven contains a product fixture for mounting the HUD product to be tested. The HUD product on the product fixture is electrically connected to the controller. The upper surface of the baking oven is provided with a transparent contoured glass, which is aligned with the product fixture. A solar simulator is located above the baking oven, with its light outlet positioned directly above the contoured glass. The solar simulator and the baking oven are electrically connected to the controller.

[0005] As a further improvement of this utility model, the baking oven is provided with an opening and closing door, one end of which is hinged to the baking oven, and the other end is detachably connected to the baking oven.

[0006] As a further improvement of this utility model, the baking oven is provided with a lifting adjustment mechanism, and the product clamp is connected to the output end of the lifting adjustment mechanism. The lifting adjustment mechanism is used to drive the product clamp to move up and down, thereby aligning the HUD product on the product clamp with the contoured glass or the opening and closing door.

[0007] As a further improvement of this utility model, the lifting adjustment mechanism includes a fixed base, which is connected to the baking oven. The fixed base is provided with a rotatable adjusting screw, and a lifting slider is sleeved on the adjusting screw. The product clamp is connected to the lifting slider.

[0008] As a further improvement of this utility model, the lifting adjustment mechanism further includes an adjustment handwheel and a reducer. The reducer is connected to the fixed base, the adjustment handwheel is connected to the input end of the reducer, and the adjustment screw is connected to the output end of the reducer.

[0009] As a further improvement of this utility model, the fixed base is provided with a plurality of guide rods, and the product clamp is provided with guide sleeves at corresponding positions of the guide rods.

[0021] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, a high-temperature and high-light resistance testing device for HUDs includes a machine base 1 and a controller 2. A baking oven 3 is fixedly installed on the machine base 1. The baking oven 3 can be any existing heating oven 3, and its specific structure is not limited in this invention. A product fixture 4 is provided inside the baking oven 3. The product fixture 4 is used to mount the HUD product to be tested. The HUD product on the product fixture 4 can be electrically connected to the controller 2; thus, the controller 2 can control the operation of the HUD product on the product fixture 4 and acquire various parameters of the HUD product during operation, including but not limited to voltage, current, and other signals. A transparent contoured glass 5 is installed on the upper surface of the baking oven 3, and the contoured glass 5 is aligned with the product fixture 4. The contoured glass 5 can capture the windshield of the car after the HUD is installed in the vehicle, thereby allowing the HUD product to be tested in a simulated vehicle environment, improving testing accuracy. A solar simulator 6 is installed above the baking oven 3. The light outlet of the solar simulator 6 is located directly above the contoured glass 5. The solar simulator 6 and the baking oven 3 are electrically connected to the controller 2. The solar simulator 6 is used to emit simulated sunlight, thereby enabling the indoor testing of the HUD product's resistance to strong light. The solar simulator 6 can be any existing type, and its specific structure is not limited in this invention.

[0024] In practical use, the HUD product is installed on the product fixture 4 and electrically connected to the controller 2 via a wiring harness. Then, the controller 2 controls the baking oven 3 and the solar simulator 6 to work. The baking oven 3 heats the HUD product on the product fixture 4, and the light emitted by the solar simulator 6 passes through the contoured glass 5 and shines on the HUD product. After that, the controller 2 can control the HUD product to work. Because the HUD product is electrically connected to the controller 2, the controller 2 can obtain various parameter information such as the voltage and current of the HUD product when it starts working or when it is working. Thus, it can determine whether the HUD product is working and whether the working parameters are normal, so as to complete the test process of the HUD product's high temperature resistance and strong light resistance.

[0025] This HUD high temperature and strong light resistance testing equipment can simultaneously test the high temperature resistance and strong light resistance of HUD products without the need for transportation and multiple product clamping, thereby improving testing efficiency and thus improving the production efficiency of HUD products.

[0026] The controller 2 can be an existing control device, and the controller 2 has a preset control program integrated in it, such as a PLC control system, etc. This utility model does not limit this.

[0027] To facilitate the installation of the product to be tested into the baking oven 3, an opening and closing door 7 is installed on the baking oven 3. One end of the opening and closing door 7 is hinged to the baking oven 3, and the other end is detachably connected to the baking oven 3. Opening the opening and closing door 7 facilitates the loading and unloading of the product on the product clamp 4; closing the opening and closing door 7 makes the baking oven 3 a closed box, which facilitates the heating of the HUD product to meet the testing requirements.

[0028] The baking oven 3 is equipped with a lifting and adjusting mechanism. The product clamp 4 is connected to the output end of the lifting and adjusting mechanism. The lifting and adjusting mechanism is used to drive the product clamp 4 to move up and down within the baking oven 3, thereby aligning the HUD product on the product clamp 4 with the contoured glass 5 or the opening and closing door 7. When the product clamp 4 is aligned with the contoured glass 5, the light emitted by the solar simulator 6 can illuminate the HUD product; when the product clamp 4 is aligned with the opening and closing door 7, it is convenient to open the opening and closing door 7 to load and unload the HUD product on the product clamp 4. By setting up a lifting and adjusting mechanism, it is convenient to load and unload the HUD product from the product clamp 4, thus improving the convenience of testing.

[0029] The lifting and adjusting assembly includes a fixed base 8, an adjusting handwheel 9, and a reducer 10. The fixed base 8 is fixedly installed inside the baking oven 3 with screws. The reducer 10 is fixedly installed on the fixed base 8. The adjusting handwheel 9 is connected to the input end of the reducer 10. An adjusting screw 11 is installed on the output end of the reducer 10. The adjusting screw 11 and the adjusting handwheel 9 are rotatably limited to the fixed base 8. A lifting slider 12 is sleeved on the adjusting screw 11, and the lifting slider 12 is slidably connected to the adjusting screw 11. The product clamp 4 is fixedly installed on the lifting slider 12. When lifting and adjusting is required, the reducer 10 is driven by rotating the adjusting handwheel 9. The reducer 10 drives the adjusting screw 11 to rotate, which in turn drives the lifting slider 12 to slide up and down on the adjusting screw 11, thereby driving the product clamp 4 to move up and down, achieving the purpose of aligning the HUD product on the product clamp 4 with the contoured glass 5 or the opening and closing door 7.

[0030] To limit and guide the lifting movement of the product clamp 4, four guide rods 13 are installed on the fixed base 8, and the four guide rods 13 are distributed at the four corner positions of the fixed base 8. Guide sleeves 14 are respectively provided on the product clamp 4 at corresponding positions of the guide rods 13. The guide rods 13 pass through the corresponding guide sleeves 14, and the guide rods 13 and guide sleeves 14 are in sliding engagement. During the rotation of the adjusting handwheel 9, the lifting slider 12 moves up and down, driving the product clamp 4 to move. The product clamp 4 causes the guide sleeves 14 to slide on the corresponding guide rods 13. The cooperation of the guide rods 13 and guide sleeves 14 limits and guides the lifting movement of the product clamp 4, improving the stability and accuracy of the adjustment.

[0031] In other embodiments, the number of guide rods 13 can be any other number, and this utility model does not limit this.

[0032] To facilitate the installation of the solar simulator 6, a mounting bracket 15 is provided on one side of the machine base 1, and the solar simulator 6 is fixedly installed on the mounting bracket 15. By setting up the mounting bracket 15, the solar simulator 6 can be installed above the baking oven 3, so that the solar simulator 6 can be fixed directly above the contour glass 5.

[0033] The lower end of the mounting bracket 15 is provided with multiple flexible feet 16. By installing the flexible feet 16, the mounting bracket 15 can be placed stably on the ground or tabletop. At the same time, it increases the friction between the mounting bracket 15 and the ground, prevents sliding and displacement, and improves the stability of use.

[0034] To facilitate the movement and handling of the baking oven 3, multiple casters 17 are installed at the lower end of the machine base 1. The casters 17 allow the machine base 1 to be easily moved, thus facilitating the handling or relocation of the baking oven 3.

[0035] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
