Description

Technical Field

[0001] This utility model relates to the field of HUD detection technology, and in particular to a HUD virtual image position detection bracket with adjustable tilt angle. Background Technology

[0002] HUD, as a display device that projects important information into the driver's line of sight, has been widely used in the automotive, aviation and other fields. In the research and development and production of HUD, the detection of its virtual image position is a key link to ensure product performance, and the detection bracket is an important auxiliary device to realize this detection process.

[0003] Currently, HUD virtual image position detection brackets on the market have many shortcomings in use. Most brackets have a fixed structure, making it difficult to flexibly and accurately adjust the tilt angle of the HUD module. When different models or different detection requirements of HUD modules need to be tested, different brackets are often required, which is not only cumbersome to operate, but also increases the testing cost.

[0004] In addition, some adjustable brackets have a limited range of adjustment methods, either only adjusting the tilt angle of the HUD module or only adjusting the spacing of the brackets, failing to achieve dual adjustment. Moreover, the adjustment process of these brackets is not smooth enough, and they are prone to jamming or shaking, resulting in unstable position of the HUD module, which in turn affects the detection accuracy of the virtual image position. At the same time, their adaptability is poor, making it difficult to meet diverse detection needs and bringing many inconveniences to the HUD detection work.

[0005] Therefore, developing a HUD virtual image position detection bracket that can achieve dual adjustment of the HUD module tilt angle and bracket spacing, and is simple to operate, stable in adjustment, and highly adaptable has become an urgent problem to be solved by those skilled in the art.

It is simple and convenient to operate, and the adjustment process is stable and controllable. It can adapt to different models of HUD modules with different detection requirements, effectively improve the accuracy and efficiency of HUD virtual image position detection, reduce detection costs, and solve the problems of inconvenient adjustment, poor adaptability, and low detection accuracy of existing detection brackets.

[0007] An adjustable tilt angle HUD virtual image position detection bracket according to an embodiment of the present invention includes a base, a mounting bracket, and a support plate. A guide rail is horizontally fixedly installed on the top of the base. Sliding brackets are symmetrically and movably installed on both sides inside the guide rail. A mounting bracket is movably installed on the top of the sliding brackets via a hinge. An adjustment seat is fixedly installed on the top of the base and in the center of the front side of the guide rail. A slider is movably installed inside the adjustment seat. A rotating shaft is provided on both the front and rear outer walls of the support plate. The rear side of the support plate is movably connected to the top of the slider via the rotating shaft. A bracket is movably installed on the front end of the support plate via the rotating shaft. A connecting seat is fixedly installed on the rear side of the bracket. Movable plates are symmetrically installed on both sides inside the connecting seat. The outer ends of the two sets of movable plates are respectively fixedly connected to two sets of sliding brackets.

[0008] Furthermore, a first lead screw is rotatably mounted in the center of the adjusting seat, and a first screw hole is opened through the slider. The first lead screw passes through the first screw hole and forms a transmission pair.

[0009] Furthermore, a second lead screw is rotatably mounted in the center of the guide rail, and a second screw hole is provided through the sliding bracket. The second lead screw passes through the second screw hole and forms a transmission pair.

[0010] Furthermore, supports are symmetrically fixedly installed at both ends of the top rear side of the base, and a display panel is fixedly installed on the inner side of the supports.

[0011] Furthermore, the mounting bracket has elongated mounting holes on both sides inside, and the HUD module can be installed on the top of the mounting bracket by bolts through the elongated mounting holes.

[0012] Furthermore, a rotating wheel is fixedly installed at the front end of the first lead screw and outside the adjusting seat.

[0013] Furthermore, a crank handle is fixedly installed at one end of the second lead screw, located outside the guide rail.

[0014] Furthermore, the display panel is detachably connected to the support by bolts, and the surface of the display panel is covered with an anti-glare film to prevent external light from interfering with the observation of the virtual image.

[0015] Furthermore, the connecting seat has an internal cavity that is adapted to the movable plate.

[0016] Furthermore, the threads at both ends of the second lead screw rotate in opposite directions, and the second screw holes in the two sets of sliding brackets are respectively adapted to the threads at both ends of the second lead screw.

[0017] The beneficial effects of this utility model are: In this invention, rotating the wheel drives the first lead screw to rotate. Utilizing the transmission pair structure between the lead screw and the slider, the slider can be driven to move linearly. Furthermore, through the linkage of the support plate, bracket, connecting seat, and movable plate, the tilt angle of the HUD module can be flexibly adjusted. Rotating the crank drives the second lead screw to rotate. With the cooperation of the oppositely helical threads at both ends and the sliding bracket, the two sets of sliding brackets can move towards or away from each other, precisely adjusting the spacing. This dual adjustment method is simple to operate, the adjustment process is smooth and controllable, and it can meet the needs of different models of HUD modules with different testing requirements, exhibiting extremely high adaptability.

[0024] like Figure 1-4 As shown, this utility model discloses an adjustable tilt angle HUD virtual image position detection bracket, including a base 1, a mounting bracket 4, and a support plate 13. A guide rail 2 is horizontally fixedly installed on the top of the base 1. Sliding brackets 3 are symmetrically and movably installed on both sides inside the guide rail 2. A mounting bracket 4 is movably installed on the top of the sliding bracket 3 via a hinge. An adjustment seat 11 is fixedly installed on the top of the base 1 and in the center of the front side of the guide rail 2. A slider 12 is movably installed inside the adjustment seat 11. A rotating shaft 16 is provided on both the front and rear outer walls of the support plate 13. The rear side of the support plate 13 is movably connected to the top of the slider 12 via the rotating shaft. A bracket 8 is movably installed on the front end of the support plate 13 via the rotating shaft 16. A connecting seat 6 is fixedly installed on the rear side of the bracket 8. Movable plates 7 are symmetrically installed on both sides inside the connecting seat 6. The outer ends of the two sets of movable plates 7 are respectively fixedly connected to two sets of sliding brackets 3.

[0025] This application discloses an adjustable tilt angle HUD virtual image position detection bracket. In use, the HUD module is first installed on top of the mounting bracket 4 using bolts through the elongated mounting holes 5 on both sides inside the mounting bracket 4. The elongated mounting holes 5 allow for easy adjustment of the HUD module's installation position to meet different detection needs. After the HUD module is installed, the virtual image it generates is displayed on the display panel 19 on the rear top of the base 1. The display panel 19 is detachably connected to the support 18 by bolts and its surface is covered with an anti-glare film to prevent external light from interfering with the observation of the virtual image, ensuring that the inspection personnel can clearly observe the virtual image.

[0026] When the tilt angle of the HUD module needs to be adjusted, the rotating wheel 20 on the outer side of the adjustment seat 11 can be rotated. The rotating wheel 20 drives the first lead screw 15 to rotate. Since the first lead screw 15 passes through the first screw hole 17 inside the slider 12 and forms a transmission pair, the rotation of the first lead screw 15 will cause the slider 12 to move linearly within the adjustment seat 11. When the slider 12 moves, it drives the support plate 13 to move through the rotating shaft on the rear side of the support plate 13. The front end of the support plate 13 is movably connected to the bracket 8 through the rotating shaft 16, thereby driving the bracket 8 and the connecting seat 6 to move. The connecting seat 6 has a receiving cavity that matches the movable plate 7. The outer end of the movable plate 7 is fixedly connected to the sliding bracket 3. Therefore, the movement of the connecting seat 6 can cause the movable plate 7 to extend and retract within the receiving cavity, while simultaneously driving the sliding bracket 3 to rotate around the hinge connected to the mounting bracket 4 as the fulcrum, thereby realizing the adjustment of the tilt angle of the HUD module.

[0027] To adjust the distance between the two sets of sliding brackets 3, the crank 10 on the outside of the guide rail 2 can be rotated. The crank 10 drives the second lead screw 9 to rotate. The threads at both ends of the second lead screw 9 turn in opposite directions, and the second screw holes 14 inside the two sets of sliding brackets 3 are respectively matched with the threads at both ends of the second lead screw 9. Therefore, when the second lead screw 9 rotates, the two sets of sliding brackets 3 will move towards or away from each other, thus adjusting the distance. During the movement of the sliding bracket 3, the part of its bottom that contacts the guide rail 2 is provided with a groove that matches the guide rail 2, and the inner wall of the groove is equipped with a wear-resistant pad, which can reduce the frictional wear between the sliding bracket 3 and the guide rail 2 and extend the service life of the bracket.

[0028] The adjustable tilt angle HUD virtual image position detection bracket described in this application, through the setting of transmission structures such as the first lead screw 15 and the second lead screw 9, can conveniently and accurately adjust the tilt angle of the HUD module and the spacing of the sliding bracket 3 to meet different detection conditions. At the same time, the connection structure of each component is rationally designed, such as the cooperation between the movable plate 7 and the connecting seat 6, and the cooperation between the sliding bracket 3 and the guide rail 2, ensuring the stability and reliability of the bracket's operation and providing good support for HUD virtual image position detection.

[0029] As a preferred example of this application, the hinge includes a fixed page and a movable page. The fixed page is welded and fixed to the top of the sliding bracket 3, and the movable page is bolted to the bottom of the mounting bracket 4. The fixed page and the movable page are rotatably connected by a pin. This hinge structure provides a strong connection and flexible rotation, ensuring stable relative rotation between the sliding bracket 3 and the mounting bracket 4, and ensuring smooth adjustment of the HUD module's tilt angle.

[0030] As a preferred example of this application, rolling bearings are installed at the connection points between the two ends of the first lead screw 15 and the adjusting seat 11. The outer ring of the rolling bearing is interference-fitted with the inner wall of the adjusting seat 11, and the inner ring is interference-fitted with the outer wall of the first lead screw 15. The rolling bearings reduce the friction between the first lead screw 15 and the adjusting seat 11 when the first lead screw 15 rotates, making the rotation of the first lead screw 15 smoother, improving the stability of the slider 12 movement, and thus ensuring the accuracy of the HUD module tilt angle adjustment.

[0031] As a preferred example of this application, the wear-resistant gasket installed on the inner wall of the groove at the bottom of the sliding bracket 3 is made of polytetrafluoroethylene (PTFE). PTFE has excellent wear resistance and a low coefficient of friction, which can further reduce frictional loss between the sliding bracket 3 and the guide rail 2, and it also has good corrosion resistance, which can extend the service life of the gasket.

[0032] As a preferred example of this application, the outer surface of the rotating wheel 20 is provided with anti-slip texture. The anti-slip texture increases the friction between the operator's hand and the rotating wheel 20, making it easier for the operator to rotate the rotating wheel 20 and preventing slippage during rotation, thus making the operation more effortless and reliable.

[0033] As a preferred example of this application, the grip portion of the crank handle 10 is covered with a rubber sleeve, the surface of which has raised anti-slip particles. The rubber sleeve is soft, which can improve the comfort of the operator when gripping the crank handle 10, while the raised anti-slip particles can enhance the anti-slip effect and ensure that the operator is not easily distracted when turning the crank handle 10.

[0034] As a preferred example of this application, the movable plate 7 has a rectangular cross-section. When the movable plate 7 with a rectangular cross-section extends and retracts within the receiving cavity of the connecting seat 6, it will not rotate relative to the other side, thus ensuring the stability of the movement of the sliding bracket 3 and ensuring the smoothness of the HUD module adjustment process.

[0035] As a preferred example of this application, the bottom of the support 18 is fixedly connected to the top of the base 1 by a countersunk bolt, the head of which is recessed into a countersunk hole inside the support 18. This connection method ensures that the bottom of the support 18 fits tightly with the top of the base 1, improving the installation stability of the support 18 and thus ensuring the stability of the display panel 19.

[0036] As a preferred example of this application, both the first lead screw 15 and the second lead screw 9 are made of high-strength alloy steel. High-strength alloy steel has high strength and hardness, can withstand large forces, ensures that the lead screw is not easily deformed during long-term use, extends its service life, and ensures the transmission accuracy of the bracket.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
