[0025] The horizontal adjustment component 3 is installed on the support frame 2 and is used to adjust the angle of the projector body 1. The horizontal adjustment component 3 includes a mounting frame 31, a hydraulic cylinder 32 and a connecting seat 33. The mounting frame 31 is welded to the two side positions of the support column 22. The hydraulic cylinder 32 is vertically installed on the mounting frame 31. Connecting seats 33 are installed on both sides of the bottom surface of the rotating plate 23. A horizontal slide groove is provided on the connecting seat 33. The output end of the hydraulic cylinder 32 is connected to a driving column, and the driving column is slidably connected in the horizontal slide groove. A pressure supply mechanism 34 for controlling the hydraulic cylinder 32 is installed on the mounting frame 31; the pressure supply mechanism 34 is used to supply or extract hydraulic oil into or out of the hydraulic cylinder 32, so that the output end of the hydraulic cylinder 32 extends or retracts, thereby driving the rotating plate 23 to rotate.
[0026] The pressure supply mechanism 34 includes a piston cylinder 341, a driving rod 342 and a piston 343. The piston cylinder 341 is mounted on the mounting frame 31. The driving rod 342 is slidably connected to the piston cylinder 341. The driving rod 342 is located inside the piston cylinder 341 and one end is connected to the piston 343. The other end of the driving rod 342 is connected to the driving frame 46. One end of the piston cylinder 341 is connected to the oil delivery hole of the hydraulic cylinder 32 through an oil pipe. Figure 6 As shown, the left end cavity of the piston cylinder 341 is filled with hydraulic oil, and the movement of the piston 343 can squeeze or suck the hydraulic oil.
[0027] A driving component 4 is also installed on the support frame 2. The driving component 4 can adjust the angle of the projector body 1 by driving the horizontal adjustment component 3 by gravity, and keep the projector body 1 in a horizontal state. The driving component 4 includes a driving arm 41, a counterweight 42 and a support bracket 43.

Both ends of the rack 44 are connected to a driving frame 46, and the driving frame 46 is connected to the input end of the pressure supply mechanism 34; under the action of gravity, the counterweight 42 always keeps the driving arm 41 in a vertical state. When the base plate 21 is placed on an inclined plane, the driving arm 41 rotates a certain angle on the support column 22 to drive the pressure supply mechanism 34.
[0028] A dust cleaning component 5 is installed on the projector body 1 and the support frame 2. The dust cleaning component 5 is used to clean dust on the surface of the lens glass 11 on the projector body 1.

During the deviation correction process of the projector body 1, the lens glass 11 can be cleaned at the same time, or the lens glass 11 can be quickly cleaned by manually pressing both sides of the projector body 1.
[0029] The working process of the present invention is as follows:
[0030] When the naked-eye 3D projector is placed on a plane that is inclined relative to the horizontal plane, the counterweight block 42 drives the driving arm 41 to rotate under the action of gravity, so that the driving arm 41 drives the gear 45 to rotate, and the gear 45 drives the rack 44 to slide to the side lower than the horizontal plane. The rack 44 drives the pressure supply mechanism 34 on this side through the driving frame 46 to supply hydraulic oil to the corresponding hydraulic cylinder 32, so that the hydraulic cylinder 32 on this side lifts one end of the rotating plate 23, and the hydraulic cylinder 32 on the other side of the support column 22 draws oil and retracts until the rotating plate 23 is in a horizontal state, thereby realizing the automatic deviation correction operation of the projector body 1.
[0031] During the sliding of the rack 44, the driving frame 46 also drives the air cylinder 52 to operate. The air cylinder 52 transports air to the air distributor block 51 and blows air out through the air holes on the air distributor block 51 to clean the dust on the surface of the lens glass 11. When there is a lot of dust on the surface of the lens glass 11, the cleaning component 5 can also be operated by reciprocatingly pressing the two sides of the projector body 1 to achieve a better cleaning effect. The operation is convenient and quick.
