Limiting bolts 405 are installed inside the limiting holes 404, and the top of the limiting bolts 405 is a rubber head. The rubber head is nested in the top of the limiting bolts 405, and the diameter of the rubber head is larger than the diameter of the limiting hole 404 and protrudes above the limiting hole 404.

[0029] The telescopic assembly 4 also includes an electric push rod 402 installed on the rear end of the panel 403. The rear end of the electric push rod 402 is bolted to the inside of the TV cabinet 1. The telescopic end of the electric push rod 402 is fixedly connected to the panel 403. A protective side plate 406 is provided on the inner side of the electric push rod 402, and a cooling fan is installed on the protective side plate 406. The protective side plate 406, the panel 403, and the base 401 form a drawer structure. The cooling fan is used to dissipate heat from the laser TV host. The cooling fan on one side of the protective side plate 406 is used for air intake, and the cooling fan on the other side of the protective side plate 406 is used for air exhaust. A guide rail is installed between the bottom of the base 401 and the TV cabinet 1 to guide the telescopic movement of the base 401.

[0030] By adopting the above technical solution, the bottom thread of the limiting bolt 405 is connected to a nut, which is located below the limiting hole 404. After the laser TV host is placed inside the base 401, multiple limiting bolts 405 are installed around the laser TV host. The rubber head of the limiting bolt 405 is in contact with the side surface of the laser TV host. The laser TV host is limited and fixed by the multiple limiting bolts 405. When it is needed, the electric push rod 402 can push the surface panel 403 forward. The surface panel 403 can drive the base 401 to move, and drive the laser TV host to move outward. The multiple limiting bolts 405 can limit and fix the laser TV host, preventing the host from moving due to slight vibration or external force. Since multiple limiting holes 404 are provided, laser TV hosts of different sizes can be adapted.

[0031] Specifically, such as Figure 4 and Figure 5 As shown, the cover plate assembly 3 includes an upper cover plate 301 that is slidably installed on the top end face of the TV cabinet 1. A telescopic rod 309 is fixed to the bottom of the upper cover plate 301, and a return spring 310 is sleeved on the outside of the telescopic rod 309. A transmission rack 306 is fixed to the bottom of the telescopic rod 309, and an electromagnet 308 is provided on the side of the telescopic rod 309. The electromagnet 308 is bonded and fixed to the transmission rack 306.

[0032] The lower part of the transmission rack 306 is meshed with an output gear 304, and the power output end of the stepper motor 305 is fixed to the side of the output gear 304. The left and right sides of the upper cover plate 301 are provided with side support plates 302 fixed inside the TV cabinet 1. The stepper motor 305 is installed on the side of one of the side support plates 302 by bolts.

[0033] An iron block 307 is magnetically attracted above the electromagnet 308. The iron block 307 is attached to the bottom of the upper cover plate 301. Two guide grooves 303 are provided.

[0034] By adopting the above technical solution, when the laser TV host is in use, the electromagnet 308 is energized, and the electromagnet 308 and the iron block 307 attract each other, which can drive the upper cover plate 301 to move downwards and drive the telescopic rod 309 to extend and retract. At the same time, the return spring 310 extends and retracts. After the upper cover plate 301 is lowered, it can be located inside the top plate of the TV cabinet 1. After the stepper motor 305 is started, it can drive the output gear 304 to rotate. The output gear 304 can drive the transmission rack 306 to move along the axial direction of the guide groove 303 through tooth meshing. The transmission rack 306 can... The telescopic rod 309 drives the upper cover plate 301 to move backward and retract into the TV cabinet 1. A guide block that is fixedly connected to the electromagnet 308 and the telescopic rod 309 is slidably installed inside the guide groove 303 on the other side. The guide block on the other side slides inside the guide groove 303. With the outward movement of the base 401, after the upper cover plate 301 retracts, unobstructed projection is achieved. Through the set cover plate assembly 3, under the action of the electromagnet 308 and the telescopic rod 309, the upper cover plate 301 can be driven to descend and retract into the TV cabinet 1 to achieve unobstructed projection.

[0035] Working principle: When the laser TV host is in use, the electromagnet 308 is energized, and the electromagnet 308 and the iron block 307 attract each other, which can drive the upper cover plate 301 to move downwards and drive the telescopic rod 309 to extend and retract. At the same time, the return spring 310 extends and retracts. After the upper cover plate 301 is lowered, it can be located inside the top plate of the TV cabinet 1. After the stepper motor 305 is started, it can drive the output gear 304 to rotate. The output gear 304 can drive the transmission rack 306 to move along the axial direction of the guide groove 303 through tooth meshing. The transmission rack 306 can drive the upper cover plate 301 to move backward through the telescopic rod 309 and retract into the interior of the TV cabinet 1. A guide block fixedly connected to the electromagnet 308 and the telescopic rod 309 is slidably installed inside the guide groove 303 on the other side. The guide block on the other side slides inside the guide groove 303. The electric push rod 402 can push the surface panel 403 to move forward. The surface panel 403 can drive the base 401 to move, which in turn drives the laser TV host to move outward. After the upper cover plate 301 retracts, unobstructed projection is achieved.
