Description

Technical Field

[0001] This application relates to the field of vehicle screen technology, and in particular to a vehicle screen mechanism and vehicle. Background Technology

[0002] In-vehicle screens are screens installed inside vehicles to display information and images. With the continuous improvement of the level of intelligence in automobiles, in-vehicle displays have become an indispensable feature in modern car cockpits.

[0003] The announcement number CN214467716U discloses a vehicle screen bracket, which includes two clamping blocks, a connecting block and a first screw. The clamping blocks clamp the headrest bracket, the two clamping blocks are connected by the first screw, the connecting block is connected to the clamping blocks, and the screen is connected and fixed to the connecting block.

[0004] During use, the aforementioned vehicle screen bracket has the display screen bolted to it, limiting its position and making it difficult to hide when not in use, resulting in poor flexibility. Summary of the Invention

[0005] To address the issues of limited screen placement due to bolted connections to vehicle screen brackets, difficulty in hiding the screen when not in use, and poor flexibility, this application provides a vehicle screen mechanism with the following technical solution: It includes a bracket with a sliding groove. A matching connector is slidably connected within the groove. A mounting bracket is rotatably connected to the connector. The screen is mounted on the mounting bracket.

[0021] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0022] This application discloses an in-vehicle screen mechanism.

[0023] Reference Figure 1 and Figure 2 The system includes a bracket 1 with two opposing sliding grooves 2. Connectors matching the dimensions of the grooves 2 are slidably connected within each groove 2. A mounting bracket 3 is rotatably connected between the two connectors. A display screen 4 is bolted to the mounting bracket 3. The bracket 1 is equipped with a drive device for driving the connectors to slide along the grooves 2. In this embodiment, the grooves 2 can be designed as arc-shaped according to the shape of the vehicle interior panel, or they can be designed as inclined according to actual conditions. The connectors include a rotating sleeve 17 slidably connected within the grooves 2. A rotating shaft 18 is fixedly connected to the mounting bracket 3, and the rotating shaft 18 is rotatably connected to the inner edge of the rotating sleeve 17.

[0024] Therefore, by starting the drive unit, the connecting piece slides along the slide groove 2. During the movement of the connecting piece, the mounting bracket 3 and the display screen 4 on the mounting bracket 3 move synchronously, thereby changing the position of the display screen 4. This allows for a hidden display screen 4, meaning that when needed, the display screen 4 can be extended out of the interior panel to a designated position, and when not in use, the display screen 4 can be retracted into the interior panel, thus improving the flexibility of the display screen 4's position.

[0025] Reference Figure 3 and Figure 4 The drive unit includes a lead screw 5 rotatably connected to a bracket 1. A bushing is installed between the bracket 1 and the lead screw 5. The lead screw 5 passes through the bushing and is rotatably connected to it. The bushing can compensate for the gap between the bracket 1 and the lead screw 5, ensuring smoother and more precise relative movement between them, and helping to reduce instability caused by excessive gap. In addition, the bushing is usually made of wear-resistant material, which can reduce the direct friction between the lead screw 5 and the bracket 1 during rotation, extending the service life of the bracket 1 and the lead screw 5.

[0026] Reference Figure 3 and Figure 4The lead screw 5 is threadedly connected to a nut 6 that matches its size. A connecting bracket 7 is mounted on the nut 6, and a mounting bracket 3 is rotatably connected to the connecting bracket 7. A drive unit for driving the lead screw 5 to rotate is mounted on the bracket 1. The drive unit includes a drive motor 8 mounted on the bracket 1. A worm gear 9 is provided at the output end of the drive motor 8. A worm wheel 10 that matches the size of the worm gear 9 is fixedly sleeved on the end of the lead screw 5 facing the drive motor 8. The worm wheel 10 and the worm gear 9 mesh with each other. The worm wheel 10 and worm gear 9 transmission structure is relatively compact and occupies little space, making it widely used in limited installation space. It is suitable for occasions requiring high transmission ratios and compact structures, such as automotive interiors. In this embodiment, a protective cover is mounted on the bracket 1. The drive motor 8, worm wheel 10, and worm gear 9 are all located inside the protective cover. The protective cover protects the components inside the cover and reduces the possibility of external impurities or components affecting the stable operation of the drive unit.

[0027] Therefore, starting the drive motor 8 causes the worm 9 at the output end of the drive motor 8 to rotate. Since the worm 9 and the worm wheel 10 mesh with each other, the worm 9 drives the worm wheel 10 to rotate during the movement. The worm wheel 10 drives the lead screw 5 to rotate, thereby causing the nut 6 and the connecting frame 7 connected to the nut 6 to slide along the length direction of the lead screw 5. During the movement, the connecting frame 7 drives the rotating shaft 18 on the mounting frame 3 to slide along the slide groove 2, thereby driving the display screen 4 on the mounting frame 3 to move.

[0028] Reference Figure 3 and Figure 4 A cover plate 15 is bolted to the bracket 1. The cover plate 15 blocks impurities and debris. A stabilizing seat 16 is bolted to the surface of the cover plate 15 facing the lead screw 5. The end of the lead screw 5 away from the worm gear 10 is rotatably connected to the stabilizing seat 16. The stabilizing seat 16 supports the lead screw 5, reduces the possibility of positional deviation during the rotation of the lead screw 5, and improves the stability of the rotation of the lead screw 5.

[0029] Reference Figure 3 and Figure 4The bracket 1 has two guide posts 11 arranged parallel to the lead screw 5, with the lead screw 5 located between the two guide posts 11. Several mounting bolts 14 pass through the bracket 1. The outer edge of each guide post 11 has threaded grooves matching the dimensions of the mounting bolts 14. The ends of the mounting bolts 14 facing the guide post 11 are threaded into these threaded grooves. Operators can remove the guide posts 11 from the bracket 1 by unscrewing the bolts, enabling detachment and greater flexibility. The connecting frame 7 has guide grooves 12 that match the two guide posts 11. The guide posts 11 slide within the guide grooves 12, limiting their position and ensuring the connecting frame 7 can only slide along the direction of the guide posts 11, thus improving stability during movement. In this embodiment, a washer ring 13 is installed on the wall of the guide groove 12. The guide post 11 slides within the inner edge of the washer ring 13. The washer ring 13 reduces direct friction between the guide post 11 and the guide groove 12, reducing wear and extending service life.

[0030] The implementation principle of this application embodiment is as follows: The drive motor 8 is started, causing the worm 9 at the output end of the drive motor 8 to rotate. Since the worm 9 and worm wheel 10 mesh with each other, the worm 9 drives the worm wheel 10 to rotate during its movement. The worm wheel 10 drives the lead screw 5 to rotate, thereby causing the nut 6 and the connecting frame 7 connected to the nut 6 to slide along the length of the lead screw 5. During the movement, the connecting frame 7 drives the rotating shaft 18 on the mounting frame 3 to slide along the slide groove 2, causing the display screen 4 on the mounting frame 3 to change position. When the rotating shaft 18 and the rotating sleeve 17 move towards the end closer to the stable seat 16, the mounting frame 3 gradually moves upward with the movement of the connecting frame 7, lifting the display screen 4 out of the interior panel. When the rotating shaft 18 and the rotating sleeve 17 move towards the end of the worm wheel 10, the mounting frame 3 gradually moves downward with the movement of the connecting frame 7, retracting the display screen 4 back into the interior panel. This application can achieve a hidden display screen 4, that is, when in use, the display screen 4 extends out of the interior panel to a designated position, and when not in use, the display screen 4 can be retracted into the interior panel, improving the flexibility of the display screen 4's position.
