Description

Technical Field

[0001] The utility model relates to the technical field of in-vehicle ceiling screens, in particular to an angle control structure for an in-vehicle ceiling screen. Background Art

[0002] An in-vehicle ceiling screen is the latest product for realizing information interaction between people and the vehicle inside the vehicle. The ceiling screen is connected to the host controller inside the vehicle through a wire harness. The main function realized is to transmit the level state of the closed screen to the host module of the vehicle when the ceiling screen is closed. Then, after the host receives the hard wire signal for closing the screen, it turns off the backlight and display screen of the ceiling screen.

[0003] However, most of the existing ceiling screens do not have an angle sensor, resulting in the inability to accurately control the opening angle of the ceiling screen. Some sensors also use the Hall method. For example, a Chinese utility model patent with an authorized announcement number of CN220391161U discloses a closing and opening control system for an in-vehicle ceiling screen, including a host controller inside the vehicle and a ceiling screen assembly. The ceiling screen assembly includes a main board and a display screen that can be flipped and opened relative to the main board. A magnet is provided on the display screen, and a Hall sensor capable of receiving the magnetic field intensity value is provided at the corresponding position of the main board. An MCU module capable of calculating and processing the magnetic field intensity value is also provided inside the main board. The induction distance between the magnet and the Hall sensor changes with the flipping of the display screen, so that the magnetic field intensity value received by the Hall sensor is variable.

[0004] The above method of cooperating and sensing through the Hall sensor to change the angle of the ceiling screen and realize the rotation of the ceiling screen, but using the Hall method results in not only a complex overall structure of the ceiling screen but also a complex circuit design, and at the same time increases the cost.
