Description

Technical Field

[0001] This utility model relates to the field of PGU display technology, and in particular to a novel PGU display stand. Background Technology

[0002] A head-up display (HUD) projects driving information such as speed, navigation, and external smart devices onto the windshield in front of the driver, allowing the driver to see important driving information without looking down or turning their head, thus enhancing driving safety by reducing the need to shift their gaze. The projection unit (PGU) is the core component of the HUD, responsible for generating the output image. It consists of a light source, optical films, a screen, and other optical components.

[0003] According to the patent application published on the Internet (authorization announcement number: CN221489595U), "A novel PGU display stand, relating to the field of optical display technology, includes a base plate and a display mechanism. The display mechanism is arranged on the outer side of the base plate. The display mechanism includes a support component, a planar reflection component, a curved mirror component, a fixing component, and a clamping component. The support component is arranged at the top of the base plate, the planar reflection component is arranged at the bottom of the support component, and the curved mirror component is arranged at the top of the support component. Through the arrangement of the display mechanism, the PGU unit module is installed and fixed, the drive board is installed, the wiring harness is connected to the PGU unit module, the small curved mirror and the large curved mirror are installed, adjusted, and fixed, the windshield is fixed by the lower clamping block and the upper clamping block, the round rod is inserted into the round hole, the hand screw is tightened, the round rod is fixed, the drive board and the PGU unit module start to work, and the image is projected onto the windshield through the reflection and refraction of the planar reflection mirror, the small curved mirror, and the large curved mirror."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The new PGU display stand lacks the function of adjusting the angle of the display screen during use, which has certain limitations. Although the simple angle flipping method can adjust the angle of the simulated glass to adapt to the simulated display of various car models, the right-angle fixing groove cannot effectively fix the glass during the flipping process because the car glass is generally curved. If the flipping is large and large, it is easy to cause shaking and bumps. Utility Model Content

[0053] See Figures 1 to 8 Based on Embodiments 1 to 3, the lifting mechanism 3 further includes a support block 31, which is fixedly connected to the top of the base plate 1. A first movable arm 32 is rotatably connected to the outside of the support block 31, and a second movable arm 33 is provided on the outside of the first movable arm 32.

A first threaded rod 39 is rotatably connected inside the limit frame 38, and a threaded block 301 is threadedly connected to the outer wall of the first threaded rod 39 to facilitate adjustment of the height of the PGU module display.

[0054] Furthermore, the threaded block 301 is rotatably connected to the inner side of the second movable arm 33, and the threaded block 301 is slidably connected to the inner side of the limiting frame 38, so that the threaded block 301 can move stably.

[0055] Furthermore, a second handwheel is fixedly connected to one end of the first threaded rod 39, and a first handwheel is fixedly connected to one end of the second worm gear 604, which facilitates better control of the rotation of the first threaded rod 39 and the second worm gear 604.

[0056] Furthermore, the second movable arm 33 is rotatably connected to the outer wall of the limiting shaft 36, and the first movable arm 32 is rotatably connected to the outer side of the connecting platform 37, so that the connecting platform 37 can rise stably.

[0057] Working principle: In actual operation, when this device is used, the glass projected by PGU is first inserted into the positioning frame 65, which serves as initial support and limitation. Then, the first handwheel can be turned to rotate the second threaded rod 602. Since the second threaded rod 602 and the U-shaped block 606 are threadedly connected, and the U-shaped block 606 can slide and limit the movement inside the load-bearing plate 605, the rotational motion of the second threaded rod 602 is converted into the linear motion of the U-shaped block 606. The U-shaped block 606 can drive the positioning block 607 to move upward, and the positioning block 607 can block the fixed position. At the opening of the frame 65, the right-angle plate 601 can be inserted into the rectangular opening of the positioning block 607. Simultaneously, when the U-shaped block 606 is raised, it will provide a contraction force to the extrusion cylinder 72, so that the pressure inside the extrusion cylinder 72 is transmitted to the upper balloon 74 and the lower balloon 73 through the pressure pipe 75. When the upper balloon 74 and the lower balloon 73 come into contact with the curved simulated glass, the upper balloon 74 and the lower balloon 73 will slowly expand along the contour surface of the simulated glass, thereby clamping and fixing the edges of the simulated scale without torsional stress, thus preserving the original shape of the simulated glass as much as possible.

[0058] This serves to reinforce and limit the projection, ensuring the stability of the projection glass during the display process. The motor 67 is activated, and its output drives the first worm gear 68 to rotate. The first worm gear 68, through the transmission of the first worm wheel 69, drives the long rod 62 to rotate. The long rod 62, through the side plate 63, drives the support frame 64 to move in a circular motion along the axis of the long rod 62, thereby achieving the purpose of adjusting the angle of the support frame 64. This makes it easier to adapt the projection glass to different usage angles, enhancing the flexibility of the device and facilitating operation by staff. Because the upper and lower balloons 74 and 73 fix the glass, the stability of the glass is maintained even during large-angle flipping changes, thus making the projection more stable and ensuring the stability and safety of the glass.

[0059] The PGU module to be displayed is placed on top of the support platform 51, which serves as an initial support and limit. Then, the telescopic rod 52 can be activated. The telescopic rod 52 can drive the fixing block 53 to slide and limit on the outside of the limiting platform 56. At the same time, the fixing block 53 can drive the positioning plate 55 to move through the short shaft 54, so that the positioning plate 55 can clamp and position the PGU module, thereby achieving the purpose of installing the PGU module. This ensures the stability of the PGU module during the working and display process and enhances the practicality of the device.

[0060] The second handwheel is cranked to rotate the first threaded rod 39. Since the first threaded rod 39 and the threaded block 301 are threadedly connected, and the threaded block 301 can slide and limit the movement inside the limiting frame 38, the rotational motion of the first threaded rod 39 is converted into the linear motion of the threaded block 301. The threaded block 301 can drive the first movable arm 32 to move, thereby adjusting the height of the support platform 51. This makes the device suitable for display environments of different heights, improves the flexibility of operation, and facilitates operation by staff.
