The application firstly provides a vehicle-mounted projection screen based on mechanical contraction, and the vehicle-mounted projection screen can be arranged on vehicles such as automobiles and trains and can also be applied to various small spaces with projection requirements. As shown in fig. 1 and 5, the vehicle-mounted projection screen 10 includes: a first slide 11, a projection screen 20, a screen support 21, a first support 22 and a first drive assembly (not shown).

The projection screen 20 is fixed on the screen support 21; one end of the first bracket 22 is rotatably connected with the first connecting part 211 of the screen bracket 21, and the other end (the end is rotatably provided with a pulley) of the first bracket 22 is slidably connected with the first slide rail 11; the first driving assembly is connected to the first connection portion 211 of the screen support 21, and the first driving assembly is used for applying a tensile force to the screen support 21 to lift and lower the projection screen 20.

Specifically, the first sliding rail 11 is disposed on a mounting surface of the vehicle-mounted projection screen 10, the mounting surface may be, but is not limited to, a top surface of a vehicle, the first sliding rail 11 is mounted on the mounting surface, and one end of the first bracket 22 is provided with a pulley that is matched with the first sliding rail 11, so that the first bracket 22 can slide on the first sliding rail 11. The projection screen 20 may be, but not limited to, a light hard projection screen, the hard projection screen 20 is not easy to shake during the vehicle walking process, the area of the hard projection screen is smaller than that of the projection screen, the imaging effect is better, and the hard projection screen is not easy to be influenced by the external light conditions.

In order to improve the projection experience in the vehicle, the projection screen 20 is fixed on the screen support 21, and the projection screen 20 is lifted and lowered through the combination of the first support 22, the first driving assembly and the screen support 21. The first bracket 22, the first driving assembly and the screen bracket 21 can be arranged on the top surface of the vehicle, as shown in fig. 2, when the vehicle does not need projection, the first bracket 22, the projection screen 20 and the screen bracket 21 can be stored in the lifting box on the roof of the vehicle through the first driving assembly in a mechanical contraction mode, so that excessive space in the vehicle is not occupied, the storage is convenient, and the use experience of a user is improved.

When the vehicle-mounted projection screen 10 is started, a user can control the lifting of the vehicle-mounted projection screen 10 by controlling the first driving component. Because first drive assembly rotates with first connecting portion 211 of screen support 21 and is connected, when the user applyed the pulling force to first drive assembly, can drive first support 22 and slide on first slide 11, first support 22 applys the pulling force to screen support 21 through first connecting portion 211 to drive screen support 21 and go up and down. Since the projection screen 20 has its own weight, the screen support 21 is subjected to gravity and tensile force. When the gravity of the screen support 21 is greater than the pulling force, the screen support 21 moves downwards, the vehicle-mounted projection screen 10 is gradually unfolded, and when the pulling force and the gravity of the screen support 21 are balanced, the screen support 21 and the projection screen 20 can be fixed, so that a user can perform subsequent operations such as projection, shadow watching and the like on the projection screen 20. When the pulling force of the screen bracket 21 is greater than the gravity, the screen bracket 21 moves upwards, the vehicle-mounted projection screen 10 gradually contracts, and the vehicle-mounted projection screen 10 can be stored in a lifting box on the roof.

In the present embodiment, the in-vehicle projection screen 10 includes a first slide 11, a projection screen 20, a screen support 21, a first support 22, and a first driving assembly. The projection screen 20 is fixed on the screen support 21; one end of the first bracket 22 is rotatably connected with the first connecting part 211 of the screen bracket 21, and the other end of the first bracket 22 is slidably connected with the first slideway 11; the first driving assembly is connected to the first connection portion 211 of the screen bracket 21, and the first driving assembly is used to apply a tensile force to the screen bracket 21 to accomplish the elevation of the projection screen 20. The vehicle-mounted projection screen 10 is characterized in that the projection screen 20 is mounted on the roof of a vehicle in a mechanical shrinkage mode through the cooperation of the support, the driving assembly, the slide rail and other assemblies, the device is stable in structure, the projection screen 20 is not prone to shaking, and projection experience is effectively improved.
