Description

Technical Field

[0001] The utility model relates to the technical field of radar interactive projection, in particular to a radar interactive projection system. Background Art

[0002] The radar interactive projection system integrates the display system and the main control system, and is equipped with a sensing module to realize interactive operation. It can support interactive touch operation by multiple people. The radar interactive projection system requires the cooperation of projection equipment for imaging interaction, among which the projection optical lens is a very important device for imaging interaction.

[0003] As shown in the application document with the prior art publication number CN219958057U, it includes a shell, the inner side of which is fixedly connected with a projection lens for radar interactive projection imaging, and the outer side of which is fixedly connected with an action shell for collision protection of the projection lens. By fixing the projection lens on the outside of the shell, it is avoided that the projection lens moves and is misaligned to affect the projection imaging effect, and the structure of the projection device is simplified. The gear rotates outside the gear plate so that the slide seat slides inside the action shell, which improves the service life of the projection lens in the radar interactive projection system. The electric telescopic rod is extended so that the cotton layer plate and the projection lens surface are elastically in contact. The rotation of the coil shaft causes the water shell to rotate and the centrifugal internal cleaning liquid flows into the cotton layer plate through the micropores. The rotation of the cotton layer plate causes the cleaning liquid to be evenly applied to the surface of the transparent lens, ensuring that the dust on the surface of the projection lens is fully cleaned, and improving the cleanliness of the projection lens.

[0004] However, the above technical solution requires the cooperation of gears and toothed plates to achieve displacement. The electric telescopic rod sets the cotton layer plate on the outside of the projection lens, and then the magnetic ring and the coil shaft are rotated to clean the surface of the projection lens. The complex technical structure leads to high cost, and it occupies a large space and is not convenient for transportation and carrying. Utility Model Content
