[0002] The shell structure of a projector refers to the covering and protective part of the projector's exterior, which is usually made up of a variety of materials and components. It is designed to protect the projector's internal components while providing an aesthetically pleasing appearance and necessary heat dissipation functions.

[0003] For example, publication number CN114280878A discloses a projector, including an optical machine module and a housing; the optical machine module includes an optical machine and a mounting bracket fixed to the bottom of the optical machine, two opposite inner side walls of the housing are respectively provided with fixing grooves, and two opposite edges of the mounting bracket are respectively inserted into the two fixing grooves; the top of the optical machine and the top of the housing are fixedly connected by a first locking member. The projector provided by the present invention has a simple structure, and is convenient and fast to assemble various components, and is firmly assembled.

[0025] like Figure 1-10 As shown, the dustproof mechanism includes a movable chamber 60, which is opened on one side of the inner wall of the shell 20.

Through the double protection of the dustproof net 61 and the dustproof baffle 46, the driving belt 55 slides in the movable cavity 60 and compresses or stretches the third spring 59, so that the driving belt 55 can slide smoothly in the movable cavity 60, thereby greatly reducing the impact of dust entry on the projector.

[0027] like Figure 1-10As shown, the support mechanism includes a rotating plate 2, which is movably arranged on the upper surface of the frame 1, and support rods 3 are symmetrically fixedly arranged on both sides of the upper surface of the rotating plate 2.

Then the connecting plate 24 is pulled outward, and the connecting plate 24 drives the baffle 21 to flip and unfold through the slider 23. When the projector is damaged or malfunctions, the projector can be quickly disassembled. When installing, repeat the above operation to insert the positioning block 27 into the groove 25 for positioning. The disassembly and assembly are convenient and easy to use.

[0030] like Figure 1-10 As shown, a projector includes a projector housing structure.

[0031] Working principle: When in use, all parts are in the initial horizontal state. The main body of the device is portable and movable by lifting the lifting rod 33. When the device is placed in the designated delivery area, the lifting rod 33 is pushed downward. The lifting rod 33 drives the driving gear 41 to rotate through the rectangular rack 34. The driving gear 41 drives the movable rod 36 to rotate through the connecting shaft 40, the second rotating shaft 38, the first transmission belt 39, and the first rotating shaft 37. The movable rod 36 drives the second bevel gear 44 and the third bevel gear 47 to rotate through the first bevel gear 43. The second bevel gear 44 drives the dust baffle 46 to flip upward more than 180 degrees through the second rotating rod 45. When in use, the dust baffle 46 flips upward to open. When not in use, the dust baffle 46 seals the housing 20. During dust prevention, the third bevel gear 47 drives the fourth bevel gear 49 to rotate through the connecting rod 48, and the fourth bevel gear 49 drives the third rotating rod 50 to rotate through the fifth bevel gear 51. The third rotating rod 50 rotates through the first driven gear 52, the third rotating shaft 53, the second transmission belt 54, the fourth rotating rod 56, the fourth rotating shaft 57 and the second driven gear 58. Under the synchronous action of the first driven gear 52 and the second driven gear 58, the driving belt 55 is driven to move from top to bottom, so that the dustproof net 61 moves to block the projector. Through the dual protection of the dustproof net 61 and the dustproof baffle 46, the driving belt 55 slides in the moving cavity 60 and compresses or stretches the third spring 59, so that the driving belt 55 can slide smoothly in the moving cavity 60, greatly reducing the impact of dust entry on the projector. When adjusting the angle, the first motor 8 drives the first screw rod 9 to rotate, the first screw rod 9 drives the first moving block 10 to move up and down, the first moving block 10 drives the movable plate 13 to deflect up and down in the fixed block 12 through the first coupling shaft 11, and the movable plate 13 drives the housing 20 to adjust the angle up and down through the first rotating rod 19, the second motor 14 drives the second screw rod 15 to rotate, the second screw rod 15 drives the second moving block 16 to move horizontally, the second moving block 16 drives the housing 20 to adjust the horizontal angle horizontally through the second coupling shaft 17 and the support rod 18, so as to adjust the angle of the projector in multiple directions, which is more flexible and convenient to use; When the shell 20 is adjusted at multiple angles, the support plate 7 always abuts against the lower surface of the shell 20. As the height of the shell 20 rises and falls, the support plate 7 is pressed downward, and the support plate 7 drives the guide block 6 to slide in the first guide rod 5 and compress the first spring 701. The support plate 7 changes with the angle of the shell 20, and the second coupling shaft 17 always adjusts the angle to fit the bottom of the shell 20. The rotating setting of the rotating plate 2 makes the support mechanism always change with the adjustment of the angle of the shell 20, thereby ensuring the stability of the angle adjustment of the projector. During disassembly and maintenance, the push-pull rod 28 is pulled outward, and the push-pull rod 28 drives the positioning block 27 to move outward and compresses the second spring 29, so that the positioning block 27 is away from the groove 25, and then the connecting plate 24 is pulled outward, and the connecting plate 24 drives the baffle 21 to flip and unfold through the slider 23. When the projector is damaged or malfunctions, the projector can be quickly disassembled to facilitate subsequent inspection and maintenance.
