Description

Technical Field

[0001] The utility model relates to the technical field of 3D display, in particular to a rotating 180-degree holographic projection display cabinet. Background Art

[0002] Holographic projection is a method of projecting three-dimensional images into space through optical technology. It uses light sources such as lasers or LEDs and transparent media to generate transparent three-dimensional images, and viewers can observe the three-dimensional effect from different angles without the use of special glasses or equipment. Holographic projection technology is based on the principle of light interference. It creates a realistic three-dimensional image that appears to be suspended in the air by dividing the light wave into two parts: the reference wave and the object wave, and cross-interfering them.

[0003] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "rotatable 180-degree holographic projection display cabinet" with the application number "CN201920974250.3". The patent mainly connects the display seat and the support column by buckling with clips. When disassembling, the buckles on both sides need to be pressed inward, and the spring seat at the center automatically lifts the support column, so that the display seat and the support column can be directly separated. After pulling out the four positioning pins on the top of the fixed plate, the display cabinet can be directly lifted to achieve the separation of the display cabinet and the support column. This operation divides the entire display cabinet into three parts, which is convenient for the transportation of the display cabinet. The separation of the display cabinet and the support column allows direct viewing of the motor and the holographic projection lamp, which is convenient for maintenance personnel.

[0004] However, the device lacks movement and lifting functions. The lack of movement will limit the flexibility and usability of the display cabinet, because it cannot be easily moved between different locations or occasions, which may lead to limited use of the display cabinet, especially when the display location needs to be frequently changed or the display cabinet needs to be relocated; secondly, since the height cannot be adjusted, the display content may not match the audience's line of sight, affecting the display effect and viewing experience. If the display cabinet is fixed in one position, it may also cause crowding or inability of the audience to properly view the display content, thereby affecting the overall display effect and audience participation.

[0005] To this end, we propose a rotating 180-degree holographic projection display cabinet. Utility Model Content

[0008] According to the rotating 180-degree holographic projection display cabinet, a plurality of first screw holes are provided at the bottom end of the cabinet body, and a plurality of second screw holes are provided on the upper surface of the universal wheel.

[0009] According to the rotating 180-degree holographic projection display cabinet, the position and size of the first screw hole are consistent with those of the second screw hole, and the universal wheels are respectively installed at the four corners of the cabinet body.

[0010] According to the rotating 180-degree holographic projection display cabinet, a hydraulic pump, an oil tank, and an oil pipe are installed inside the cabinet body. The hydraulic pump is connected to the oil tank through a first oil pipe, and the hydraulic pump is connected to the hydraulic cylinder through a second oil pipe.

[0011] According to the rotating 180-degree holographic projection display cabinet, the hydraulic pump, the hydraulic cylinder, and the motor are all electrically connected to the controller, and the oil tank is filled with hydraulic oil.

[0012] According to the rotating 180-degree holographic projection display cabinet, a roller track is arranged on the upper surface of the support seat, the roller track is in a circular shape, and a roller is movably connected inside the roller track.

[0013] According to the rotating 180-degree holographic projection display cabinet, the first connecting members are evenly distributed around the bottom midpoint of the holographic projector, each of the rollers evenly corresponds to a roller track, and the rollers can rotate freely in the roller track.

[0014] The beneficial effects of the utility model are as follows: the lifting function of the holographic projector is realized through the hydraulic rod, piston rod, hydraulic pump, oil tank, oil pipe and hydraulic oil, so that the height of the projector can be adjusted as needed, so that the projection effect is better in different scenes; the holographic projector can be rotated through the motor and the second connecting piece, so that the direction and angle of the projector can be changed, so that it can be projected to different positions and angles, thereby improving the flexibility and coverage of the projection; the holographic projector can be supported to rotate along the roller track through the first connecting piece, the third connecting piece, the roller and the shaft; this design allows the projector to rotate freely in the horizontal direction, thereby increasing the diversity and adjustability of the projection, and adapting to more projection needs and scenes; the mobile flexibility and stability of the cabinet are increased through the universal wheels, so that it can be easily moved on different grounds, thereby reducing the effort and difficulty of carrying, and improving work efficiency and convenience of operation; the operator can control and adjust the hydraulic system, the motor and the holographic projector through the controller, thereby improving the intelligence and controllability of the equipment.

The universal wheel 2 is made of high-strength engineering plastics or rubber, has good bearing capacity and wear resistance, and is suitable for movement and rotation in different occasions.

[0026] A plurality of first screw holes are formed at the bottom end of the cabinet body 1 , and a plurality of second screw holes are formed on the upper surface of the universal wheel 2 .

[0027] The position and size of the first screw hole are consistent with those of the second screw hole. The universal wheels 2 are respectively installed at the four corners of the cabinet 1. The installation position and number of the universal wheels 2 can be adjusted according to the size and load conditions of the cabinet 1 to ensure the stability and balance of the cabinet during movement and operation.

[0028] A hydraulic pump, an oil tank and an oil pipe are installed inside the cabinet 1. The hydraulic pump is connected to the oil tank through a first oil pipe, and the hydraulic pump is connected to the hydraulic cylinder 5 through a second oil pipe. The hydraulic pump and the hydraulic cylinder 5 use high-quality sealing materials, such as rubber or polyurethane sealing rings, to ensure the stability and sealing of the hydraulic system and reduce the risk of leakage and failure.

[0029] The hydraulic pump, hydraulic cylinder 5 and motor 9 are all electrically connected to the controller 3, and the oil tank is filled with hydraulic oil.

[0030] The upper surface of the support seat 6 is provided with a roller track 11, which is in a circular ring shape. A roller 13 is movably connected inside the roller track 11. The roller track 11 is made of wear-resistant synthetic material or stainless steel to reduce friction and improve rolling efficiency.

[0032] Working principle: First, the hydraulic pump transports the hydraulic oil from the oil tank to the hydraulic cylinder 5 through the oil pipe. The hydraulic cylinder 5 is provided with a piston rod 4. When the hydraulic oil enters the hydraulic cylinder 5, the pressure of the hydraulic oil acts on the piston on the piston rod 4 to make it extend outward. This telescopic movement is transmitted to the holographic projector support seat 6 through the hydraulic rod 4, thereby realizing the vertical lifting of the holographic projector 7. The motor 9 controls the second connecting piece 10 to rotate through the controller 3. The second connecting piece 10 is connected to the holographic projector 7.

The universal wheels 2 at the bottom of the cabinet are fixed to the bottom of the cabinet 1 through threaded connections. These universal wheels 2 have the ability to rotate 360 ​​degrees, so that the cabinet 1 can move freely on the ground. The controller 3 is connected to the hydraulic system, the motor 9 and the holographic projector 7. The controller 3 controls the working state of the hydraulic pump in the hydraulic system by sending instructions, and adjusts the flow of hydraulic oil, thereby achieving height adjustment of the holographic projector 7; at the same time, the controller 3 can also control the speed and direction of the motor 9, as well as the rotation angle of the holographic projector 7, so that the operator can flexibly adjust the working state and projection effect of the equipment.
