The present invention relates to the technical field related to projection display, and specifically relates to a ring-curtain type 360° panoramic holographic projection display device, which includes a projection display body, a clamping frame slidingly connected to the surface of a connecting seat, and a gear sleeve glued on the surface of a light guide mirror. The surface of the gear sleeve is meshed with gears, the surface of the filter liquid capsule is extruded with a filter, the surface of the filter is glued with a connecting plate, the connecting plate is slidably connected to the surface of the threaded rod, and the third motor is screwed to the inner wall of the projection mirror. The beneficial effect is: when processing the projected content, the third motor is adjusted counterclockwise to separate the filter from the filter liquid capsule, and the filter liquid capsule remains in an opaque state. At this time, the projected content can be processed, and it is adjusted clockwise during use The third motor, the filter lens is squeezed on the surface of the filter liquid capsule, so that the filter liquid capsule presents a light-transmitting state, which improves the definition of projection, thereby ensuring the quality of use of the holographic projector, and is suitable for promotion.

The invention discloses a projection device with peripheral wireless connection, relates to the technical field of projection devices, and solves the problem that the existing projection devices do not have the function of adjusting the angle and inclination, so it is laborious to manually adjust these projection devices and the work efficiency is low. Not high and very troublesome. A projection device with peripheral wireless connection, including an inclination adjustment device and an angle adjustment device; the inclination adjustment device is fixedly connected to one side of a support rod on a base; the angle adjustment device is movably connected in a mounting groove inside the base. The projector of this device is fixed on the top of the support plate. When adjusting the angle and inclination of the projector, the personnel do not need to move the projector to adjust, but adjust the projector through the inclination adjustment device and the angle adjustment device. Simple and convenient, improve work efficiency.

The invention relates to a vehicle-mounted projection device, which is used for being installed in the interior of a vehicle interior ceiling provided with an installation opening, and includes a flipping component, a rotating component, a projection device and a projection controller. The flipping component includes a flipping shaft and a first motor, and the flipping shaft It is used to transversely penetrate the installation opening, and the two ends of the turning shaft are respectively used for rotatable connection with the interior ceiling on both sides of the installation opening. The first motor is used to drive the turning shaft to rotate; the rotating assembly includes a rotating shaft and a second motor. The motor is fixedly connected with the flipping shaft, and the rotating shaft is rotatably connected with the output shaft of the second motor; the projection device is fixedly connected with the rotating shaft; the projection controller is electrically connected with the first motor and the second motor respectively, and is used to control the operation of the first motor so as to drive the projection device to turn over to the outside of the installation opening, and to control the operation of the second motor to drive the projection device to rotate. The in-vehicle projection device embodying the present invention can have both in-vehicle projection and out-vehicle projection functions.

The invention discloses a rotating lens and projection equipment, belonging to the technical field of lenses. The present invention proposes a rotating lens, which includes a lens front group, a rotating prism group, and a lens rear group, which sequentially pass through the lens front group, rotating prism group, and lens rear group along the light propagation direction; the lens front group, lens The rear group is mainly used for imaging and magnification; the rotating prism group is used for changing the direction of outgoing light. The rotating lens of the present invention can change the direction of outgoing light, and the projection device using the rotating lens of the present invention can change the projection angle and picture position without changing the placement method, such as projecting on side walls and ceiling walls. The system of the invention is simple, easy to use and reliable in performance.
