Description

Technical Field

[0001] This utility model belongs to the technical field of automotive optical testing equipment. Specifically, this utility model relates to a secondary reflector adjustment device for a HUD testing platform. Background Technology

[0002] HUD (Head-Up Display) technology originated in the military field, initially used in aircraft. It projects important flight information such as altitude, speed, and heading onto the windshield through optical reflection, allowing pilots to maintain a level line of sight and observe information on the instrument panel, avoiding frequent head-up and down movements that could distract them. In recent years, HUD technology has gradually entered the automotive field. Similar in concept to aircraft HUDs, automotive HUDs can project essential driving information, such as navigation, messages, WeChat, and phone calls, onto the windshield, allowing drivers to see important information without looking down. In HUD testing platforms, the angle adjustment of the secondary reflector is crucial for optical path calibration.

[0003] Chinese Patent (Publication No.: 207817310U) discloses a HUD optical path imaging inspection device, comprising: a simulation device simulating a windshield, a first guide rail opposite to the simulation device, an optical engine device for setting an optical engine, an imaging mirror device for imaging, and at least one reflector device for reflecting the optical path; wherein, the optical engine device, the imaging mirror device, and the reflector device are provided with detachable and fixable assembly / disassembly components to the guide rail; the optical engine device, the imaging mirror device, and the reflector device are provided with a first adjustment mechanism for adjusting their own height; the reflector device and the simulation device are provided with a second adjustment mechanism for adjusting their own angle. However, this patent requires tools to disassemble the rotating shaft, and the operation is cumbersome when replacing the reflector or performing maintenance. Utility Model Content

[0004] This utility model is designed to solve the above-mentioned problems and aims to provide a secondary reflector adjustment device for a HUD test platform that allows for convenient replacement and adjustment of the secondary reflector. To achieve the above objective, the technical solution adopted by this utility model is as follows: a secondary reflector adjustment device for a HUD test platform, comprising a primary reflector 1 and a secondary reflector 2, and a base. The primary reflector is mounted on the base, which is provided with a fixing structure and an angle adjustment structure. The secondary reflector is mounted on the fixing structure and the angle adjustment structure.

[0005] The fixed structure includes a support base, which is mounted on a base. Permanent magnets are arranged on both sides of the secondary reflector. The permanent magnets are connected to a magnetically attracted rotating shaft, which cooperates with the support base.

[0006] The support base includes a first support plate, one end of which is provided with a rotating shaft groove, and the magnetic rotating shaft is located in the rotating shaft groove.

[0007] The angle adjustment structure includes a second support plate, which is mounted on a base. A threaded seat is connected to the second support plate, and a screw is disposed within the threaded seat. An abutment block is disposed on the secondary reflector, and the screw is connected to the abutment block.

[0008] A rotating handle is provided at one end of the screw.

[0009] The base is provided with a fixed seat, the fixed seat is provided with a sliding groove, and the first-stage radiation mirror is provided with a sliding plate, which cooperates with the sliding groove.

[0010] The fixed base includes a third support plate, which is connected to the base. A connecting plate is connected to the third support plate, and a sliding groove is provided on the connecting plate. Bolts are provided on the connecting plate and are connected to the sliding plate.

[0011] The base is provided with a fourth support plate and a fifth support plate, and a wind baffle is provided between the fourth support plate and the fifth support plate.

[0012] The base includes a base plate, on which threaded mounting holes are provided at equal intervals.

[0013] The technical advantages of this invention are as follows: the magnetic swivel is attracted to the swivel groove, allowing the secondary reflector to be directly removed by overcoming magnetic force, facilitating the replacement of the secondary reflector and simplifying maintenance. It enables tool-free, quick assembly and disassembly of the secondary reflector; the magnetic swivel also serves as a connecting component, allowing the secondary reflector to be rotatably connected to the support base, facilitating angle adjustment.

[0014] When adjusting the angle of the secondary reflector, rotating the screw generates axial movement, which pushes the abutment block. The movement of the abutment block causes the secondary reflector to rotate around the magnetic axis, thereby adjusting the angle of the secondary reflector around the magnetic axis. An angle adjustment within a range of ±3° is achieved. The screw is threadedly connected to the threaded seat, and the self-locking function of the threaded connection ensures stable position after adjustment. Attached Figure Description

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0025] like Figures 1-7As shown, a secondary reflector adjustment device for a HUD testing platform includes a primary reflector 1 and a secondary reflector 2, and a base 3. The primary reflector 1 is mounted on the base 3, which is equipped with a fixing structure 4 and an angle adjustment structure 5. The secondary reflector 2 is mounted on the fixing structure 4 and the angle adjustment structure 5. The primary reflector 1 acts as the first reflector, working with the secondary reflector 2 to complete the transmission of light and the projection of the image. The base 3 serves as the basic support structure for the entire adjustment device, supporting all other components and providing a stable mounting platform. The fixing structure 4 is used to connect the secondary reflector 2 and also allows for easy replacement. The angle adjustment structure 5 can adjust the angle of the secondary reflector 2 to improve the projection effect.

[0026] The fixing structure 4 includes a support base 41, which is mounted on the base 3. Permanent magnets 401 are arranged on both sides of the secondary reflector 2, and each permanent magnet 401 is connected to a magnetically attached rotating shaft 402. The magnetically attached rotating shaft 402 engages with the support base 41. The support base 41 is fixedly connected to the base 3 and has grooves that engage with the magnetically attached rotating shaft 402. By arranging permanent magnets 401 on both sides of the secondary reflector 2 and connecting them to the magnetically attached rotating shaft 402, the permanent magnets 401 and the magnetically attached rotating shaft 402 are attracted to the support base 41, thus fixing the secondary reflector 2 and facilitating easy replacement and maintenance. The permanent magnets 401 provide magnetic force, enabling tool-free quick assembly and disassembly of the secondary reflector 2 in conjunction with the support base 41. The magnetically attached rotating shaft 402 serves as a connecting component, allowing the secondary reflector 2 to rotate on the support base 41 for easy angle adjustment.

[0027] The support base 41 includes a first support plate 411, one end of which is provided with a pivot groove 412, and a magnetic pivot 402 is located in the pivot groove 412. The first support plate 411 is fixedly connected to the base 3. The pivot groove 412 has an open structure at one end, and the magnetic pivot 402 can be placed in the pivot groove 412. When removing it, the secondary reflector 2 can be directly removed by overcoming the magnetic force, which is convenient for use.

[0028] The angle adjustment structure 5 includes a second support plate 501, which is mounted on the base 3. A threaded seat 502 is connected to the second support plate 501, and a screw 503 is installed inside the threaded seat 502. An abutment block 504 is installed on the secondary reflector 2, and the screw 503 is connected to the abutment block 504. The second support plate 501 supports the threaded seat 502, which provides the foundation for the threaded connection of the screw 503. The screw 503 passes through the threaded seat 502 and connects to the abutment block 504. The threaded connection allows for axial movement control of the screw 503. The screw 503 is connected to the abutment block 504, which is connected to one side of the secondary reflector 2. In use, the screw 503 rotates to generate axial movement, pushing the abutment block 504. The movement of the abutment block 504 causes the secondary reflector 2 to rotate around the magnetic shaft 402, thereby achieving angle adjustment of the secondary reflector 2 around the magnetic shaft 402. Angle adjustment within a range of ±3° is achieved. The screw 503 is threadedly connected to the threaded seat 502, and the self-locking function of the threaded connection ensures that the position is stable after adjustment.

[0029] A rotating handle 6 is provided at one end of the screw 503. The rotating handle 6 is connected to the screw 503. The operator can manually rotate the rotating handle 6 to drive the screw 503 to rotate, which facilitates the rotation of the screw 503 and makes it easy to use.

[0030] A fixed seat 7 is provided on the base 3, and a sliding groove 701 is provided on the fixed seat 7. A sliding plate 101 is provided on the primary reflector 1, and the sliding plate 101 cooperates with the sliding groove 701. The sliding groove 701 is a T-shaped sliding groove. When the position of the primary reflector 1 needs to be adjusted, the sliding plate 101 can move within the sliding groove 701 to adjust the position of the primary reflector 1. This allows for the adjustment of the position of the primary reflector 1 on the base 3, adapting to the horizontal or vertical installation requirements of primary reflectors 1 of different sizes.

[0031] The fixed base 7 includes a third support plate 702, which is connected to the base 3. A connecting plate 703 is connected to the third support plate 702. A sliding groove 701 is provided on the connecting plate 703. The connecting plate 703 is provided with bolts 704, which are connected to the sliding plate 101. The third support plate 702 is connected to the base plate 304 of the base 3. The third support plate 702 is used to connect the connecting plate 703. The third support plate 702 and the connecting plate 703 are in an L-shaped structure. The sliding groove 701 is opened on the connecting plate 703. The sliding plate 101 has a row of threaded grooves. The bolts 704 pass through the connecting plate 703 and connect to the sliding plate 101. This allows the first-stage reflector 1 to be fixed after adjustment, preventing movement.

[0032] The base 3 is provided with a fourth support plate 301 and a fifth support plate 302, and a wind deflector 303 is provided between the fourth support plate 301 and the fifth support plate 302. The fourth support plate 301 and the fifth support plate 302 are used to fix the wind deflector 303. The fourth support plate 301 is a fixed plate, and the fifth support plate 302 is a telescopic plate, which facilitates the adjustment of the wind deflector 303. The wind deflector 303 blocks wind and dust, and can also block external interference light to a certain extent.

[0033] The base 3 includes a base plate 304, on which threaded mounting holes 305 are provided at equal intervals. The base plate 304 is used to fix the entire device. The threaded mounting holes 305 are M4 mounting holes, which are arranged in a 10×10 matrix layout at a certain interval, compatible with commercially available optical component brackets (such as Thorlabs standard parts). Filter brackets or sensor fixtures can be quickly installed with bolts without the need for additional machining of adapter parts.

[0034] The role and effect of the embodiments

[0035] The magnetic hinge 402 is attached to the hinge groove 412, allowing the secondary reflector 2 to be directly removed by overcoming magnetic force, facilitating replacement and maintenance. This enables tool-free quick assembly and disassembly of the secondary reflector 2. The magnetic hinge 402 also serves as a connecting component, allowing the secondary reflector 2 to be rotatably connected to the support base 41, facilitating angle adjustment.

[0036] When adjusting the angle of the secondary reflector 2, rotating the screw 503 causes axial movement, which pushes the abutment block 504. The movement of the abutment block 504 causes the secondary reflector 2 to rotate around the magnetic shaft 402, thereby achieving angle adjustment of the secondary reflector 2 around the magnetic shaft 402. Angle adjustment within a range of ±3° is achieved. The screw 503 is threadedly connected to the threaded seat 502, and the self-locking function of the threaded connection ensures stable position after adjustment.
