An installation groove is formed in the middle of the top of the mounting seat. A driving motor is fixedly installed inside the installation groove. A transmission component is provided at the output end of the driving motor. Pad feet are fixedly installed at both ends of the bottom of the bottom plate. Universal wheels are provided above the four avoidance grooves. The transmission component is in transmission connection with the four universal wheels. When the driving motor operates, power is output to the four universal wheels through the transmission component, so that the four universal wheels extend outwards and move down to the ground to support the main body of the holographic imaging device.

[0007] Preferably, the transmission component includes a driving bevel gear fixedly installed at the output end of the driving motor. A driven bevel gear is meshed and connected to one side of the surface of the driving bevel gear. A rotating rod is fixedly installed in the middle of the driven bevel gear. Threaded rods are fixedly installed at both ends of the rotating rod. Positioning seats are rotatably installed at the ends of the two threaded rods away from each other. The bottoms of the two positioning seats are fixedly connected to the top of the mounting seat.

[0008] Preferably, threaded sleeves are threadedly connected to the surfaces of the threaded rods. Limit blocks are fixedly installed at the bottoms of the two threaded sleeves through connection blocks. Limit grooves are formed on both sides of the top of the mounting seat. The two limit blocks are slidably installed inside the two limit grooves.

[0009] Preferably, moving beams are fixedly installed on both sides of the threaded sleeves through support arms. Rectangular sleeves are fixedly installed at both ends of the two moving beams. Sliding sleeves are fixedly installed through support rods in the middle of the bottoms of the two moving beams. Slide rods are inserted into the two sliding sleeves. One ends of the two slide rods close to each other are fixedly connected to both sides of the mounting seat. The other ends of the two slide rods away from each other are fixedly connected to the upper part of the bottom plate through support frames.

[0010] Preferably, rectangular rods are movably inserted into the rectangular sleeves. Universal wheels are rotatably installed at the bottoms of the four rectangular rods. Strip-shaped grooves are formed on one side of the four rectangular sleeves close to the mounting seat. Connecting arms are fixedly installed on the upper parts of the four rectangular rods on the side close to the strip-shaped grooves. The four connecting arms are respectively installed inside the four strip-shaped grooves. And the ends of the four connecting arms away from the rectangular rods all extend outside the strip-shaped grooves and are all fixedly installed with vertical rack teeth.

[0011] Preferably, a limiting sleeve is fixedly installed on one side of the rectangular sleeve away from the driving motor through a connecting rod, and a limiting rod is inserted between the interiors of two limiting sleeves on the same side. Both ends of the two limiting rods are fixedly connected to the inner walls on both sides of the holographic imaging device body through mounting strips.

[0012] Preferably, sliders are fixedly installed on the upper parts on both sides of the four rectangular rods, and sliding grooves are formed on the inner walls on both sides of the four rectangular sleeves. The sliders are respectively slidably installed inside the corresponding sliding grooves.

[0013] Preferably, a tooth column is meshed and connected to the lower part on one side of the vertical rack. Both ends of the four tooth columns are rotationally connected to the four rectangular sleeves through a rotating frame. A horizontal rack is meshed and connected to the lower part of the tooth column. Both ends of the bottoms of the four horizontal racks are fixedly connected to the upper part of the bottom plate through a fixing rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) During operation, since an edge computing unit is provided inside the computer, which is equipped with an AI chip, and is combined with the microphone array, voice recognition chip, high-definition camera, depth sensor, environment sensor, and biological sensor provided on the holographic imaging device body, real-time processing of multi-modal data of the digital human is realized;

[0016] When it is necessary to move the position of the holographic imaging device body, the operator starts the driving motor to drive the driving bevel gear to rotate. The driving bevel gear drives the rotating rod to rotate through the driven bevel gear. When the rotating rod rotates, it drives the two threaded rods to rotate along the two positioning seats. Since the two threaded rods have opposite directions, when the two threaded rods rotate, they will drive the two threaded sleeves to move away from each other. When the threaded sleeves move, they both drive the limiting blocks to slide inside the limiting grooves through the connecting blocks, increasing the stability when the two threaded sleeves move;

[0017] (2) When the two threaded sleeves move, they both push the two moving beams to move away from each other through the support arms. When the two moving beams move, they both drive the sliding sleeves to slide along the surface of the sliding rods through the support rods, increasing the stability when the two moving beams move. When the two moving beams move away from each other, they drive the four universal wheels to translate and extend outward through the four rectangular sleeves and the four rectangular rods. When the four rectangular sleeves translate, they both drive the limiting sleeves to slide along the surface of the limiting rods through the connecting rods, improving the stability when the four rectangular sleeves move;

[0018] When the four rectangular sleeves move outward, they drive the tooth columns to move through the rotating frames, and through the cooperation of the four horizontal racks, the four tooth columns rotate along the rotating frames. When the tooth columns rotate, they drive the connecting arms to move downward along the inside of the strip-shaped grooves through the vertical racks. When the connecting arms move downward, they drive the rectangular rods to move downward along the inside of the rectangular sleeves. When the rectangular rods move, they drive the sliders to slide along the inside of the sliding grooves, improving the stability of the downward movement of the rectangular rods. When the rectangular rods move downward, they drive the four universal wheels to move downward to contact the ground and lift the entire device, enabling the operator to push the holographic imaging device main body to drive the four universal wheels to roll, thus conveniently moving the device to a different position;

[0019] (3) This digital human multi-modal interactive holographic imaging device is very convenient to move to a different position without manual handling, thus reducing the labor intensity and improving the work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
