[0022] refer to Figure 1 、 Figure 3 as well as Figure 8 A motor 4 for controlling the rotation of the threaded rod 9 is fixedly installed on one side of the protective box 1. The fixed rod 10 and the protective box 1 are fixedly connected, the sixth rotating shaft 45 and the fixed plate 23 are rotatably connected, the upper part of the universal shaft 43 and the fixed plate 23 are rotatably connected, the lower part of the universal shaft 43 and the movable seat 11 are rotatably connected, the seventh rotating shaft 46 and the movable seat 11 are rotatably connected, and the third rack 39 and the movable seat 11 are slidingly connected.

[0023] refer to Figure 1 as well as Figure 2A sensor 47 is provided on one side of the TV body 2, a controller 48 for controlling the power on of the TV body 2 is provided on the upper part of the protective box 1, a bracket 3 is provided on the lower part of the TV body 2, and a second gear 18 is rotatably connected to one side of the movable seat 11. The second gear 18 is fixedly connected to the first connecting rod 17. A slide groove 16 is opened inside the protective box 1, and the first connecting rod 17 and the slide groove 16 are slidably connected.

[0025] refer to Figure 1 as well as Figure 3 The side of the movable seat 11 away from the detection camera 15 is fixedly connected to the first rack 13, the first rack 13 is meshed with the first gear 12, the first gear 12 is fixedly connected to the first rotating shaft 5, the first rotating shaft 5 and the protective box 1 are rotationally connected, the first rotating shaft 5 passes through the protective box 1 and extends to the upper part of the protective box 1.

[0026] refer to Figure 1 as well as Figure 3 The first rotating shaft 5 is connected to the first belt 6, and the first belt 6 is connected to the second rotating shaft 7 on the side away from the first rotating shaft 5. The second rotating shaft 7 is rotationally connected to the protective box 1, and the second rotating shaft 7 is fixedly connected to the protective door 8.

[0027] In this embodiment, when the TV body 2 is turned on and the sensor 47 does not detect anyone in the viewing area for a few minutes, the motor 4 fixedly installed on one side of the protective box 1 will start, causing the threaded rod 9 set at its output end to rotate. The rotation of the threaded rod 9 will cause the threaded movable seat 11 to slide on the sliding fixed rod 10 toward the protective door 8. When the movable seat 11 moves, it will drive the fixedly connected first rack 13 to move together. The first rack 13 will cause the meshing first gear 12 to drive the first rotating shaft 5 to rotate. The rotation of the first rotating shaft 5 will cause the transmission-connected first belt 6 to drive the second rotating shaft 7 to rotate. The rotation of the second rotating shaft 7 will drive the fixedly connected protective door 8 to flip, that is, it will eventually open the protective door 8, so that the detection camera 15 can move to the outside of the protective box 1 for detection. When the moving seat 11 moves toward the protective door 8, the first connecting rod 17 fixedly connected to the second gear 18 will slide first in the horizontal part of the slide groove 16. At this time, the first connecting rod 17 and the second gear 18 will not rotate. When the detection camera 15 moves out of the protective box 1, the baffle 22 fixedly connected to the inside of the protective box 1 will block the third rack 39 slidingly connected to the inside of the moving seat 11 when the moving seat 11 continues to move. That is, under the action of the baffle 22, the third rack 39 will move toward the second spring 40 and compress the second spring 40. Finally, the third rack 39 will move toward the second spring 40 and compress the second spring 40. The three racks 39 rotate the meshing fourth gear 41. The rotation of the fourth gear 41 rotates the fixed seventh rotating shaft 46. The rotation of the seventh rotating shaft 46 drives the universal shaft 43 to rotate via the third belt 42. The rotation of the universal shaft 43 drives the sixth rotating shaft 45 to rotate via the fourth belt 44 connected to the upper part of the universal shaft 43. That is, at this time, the sixth rotating shaft 45 drives the rotating base 24 to rotate one circle, which makes the detection camera 15 fixedly connected to the upper part of the rotating base 24 rotate one circle, so as to facilitate the detection of the surroundings of the room. When the detection camera 15 rotates one circle, continuing to move the moving seat 11 will cause the first connecting rod 17 to slide into the inclined part of the slide groove 16. At this time, the first connecting rod 17 will drive the fixedly connected second gear 18 to rotate. The rotation of the second gear 18 will cause the meshingly connected second rack 21 to slide inside the moving seat 11. The sliding of the second rack 21 will cause the meshingly connected third gear 19 to rotate, and the third gear 19 will cause the fixedly connected third rotating shaft 20 to rotate. The rotation of the third rotating shaft 20 will drive the fixedly connected fixing plate 23 to tilt downward, which is convenient for tilting the angle of the detection camera 15 downward, so as to facilitate detection under the TV body 2 and prevent people from being under the TV body 2 and turning off the TV body 2. When no people are detected by the rotation of the detection camera 15 and the tilt detection of the detection camera 15, the controller 48 arranged on the upper part of the TV body 2 will disconnect the power supply of the TV body 2, so that the TV body 2 is closed automatically, which is convenient for improving detection accuracy and energy saving effect.

[0028] Example 2 refer to Figure 1 、 Figure 4 as well as Figure 6 The first rotating shaft 5 is transmission-connected to the second belt 14, and the second belt 14 is transmission-connected to the fourth rotating shaft 25 on the side away from the first rotating shaft 5. A cleaning mechanism is provided at the lower part of the fourth rotating shaft 25, and the cleaning mechanism includes a disc 26 fixedly connected to the lower part of the fourth rotating shaft 25, and the disc 26 is rotationally connected to the protective box 1. The upper part of the disc 26 is rotationally connected to the ratchet 28, and the ratchet 28 is fixedly connected to the fifth rotating shaft 29. The fifth rotating shaft 29 is rotationally connected to the fixed frame 33, and the fixed frame 33 and the protective box 1 are fixedly connected.

[0029] refer to Figure 6 A pawl 27 is provided on the upper part of the disc 26 , and a torsion spring is provided between the disc 26 and the pawl 27 to always keep the teeth on the ratchet 28 and the pawl 27 in contact with each other.

[0030] refer to Figure 6 as well as Figure 7 The upper part of the fifth rotating shaft 29 is fixedly connected with a cylinder 34, the surface of the cylinder 34 is fixedly connected with a spiral slide 35, the outer sleeve of the cylinder 34 is provided with a lifting sleeve 36, the inner part of the lifting sleeve 36 is fixedly connected with a pin 37, and the pin 37 and the spiral slide 35 are movably connected.

[0031] refer to Figure 6 as well as Figure 7 The lower part of the lifting sleeve 36 is fixedly connected to the first spring 38, and the side of the first spring 38 away from the lifting sleeve 36 is fixedly connected to the fixed frame 33. The upper part of the lifting sleeve 36 is fixedly connected to the cleaning plate 31. The side of the cleaning plate 31 close to the detection camera 15 is provided with multiple cleaning brushes 32 for cleaning the surface of the detection camera 15. The outer sleeve of the lifting sleeve 36 is provided with a limit sleeve 30.

[0032] In this embodiment, when the detection camera 15 is stored inside the protective box 1 after the detection is completed, when the detection camera 15 moves to the cleaning brush 32, the first rack 13 will be meshed with the first gear 12 to make the first rotating shaft 5 rotate in the opposite direction. At this time, the first rotating shaft 5 will drive the fourth rotating shaft 25 to rotate through the second belt 14 connected to the transmission. The rotation of the fourth rotating shaft 25 will cause the lower fixedly connected disc 26 to rotate together, and the disc 26 will cause the upper pawl 27 to rotate. At this time, under the action of the pawl 27 and the ratchet 28, the pawl 27 will push the ratchet 28 to rotate together, that is, the ratchet 28 will drive the fixedly connected fifth rotating shaft 29 to rotate, and the rotation of the fifth rotating shaft 29 will cause the fixedly connected cylinder 34 to rotate. At this time, the pin 37 fixedly connected inside the lifting sleeve 36 is at the lowermost edge of the spiral slideway 35 fixedly connected to the surface of the cylinder 34; When the cylinder 34 drives the spiral slide 35 to rotate slightly, the spiral slide 35 does not block the pin 37. At this time, under the action of the first spring 38 fixedly connected to the lower part of the lifting sleeve 36, the lifting sleeve 36 will move upward rapidly, that is, the lifting sleeve 36 will drive the cleaning plate 31 fixedly connected above to move upward, and the cleaning plate 31 will enable the multiple cleaning brushes 32 set near the side of the detection camera 15 to clean the surface of the detection camera 15. At this time, the detection camera 15 continues to move toward the inside of the protective box 1, and the spiral slide 35 above the cylinder 34 The slide 35 will press the pin 37 downward, and will eventually restore the lifting sleeve 36 to its original position. The first spring 38 will be in a compressed state again. At the same time, the height of the cleaning plate 31 is located below the fixed plate 23 to prevent it from affecting the outward movement of the detection camera 15. When the detection camera 15 moves outward to drive the first rotating shaft 5 to rotate, the ratchet 28 will not be driven to rotate under the action of the pawl 27 and the ratchet 28. That is, the positions of the lifting sleeve 36, the cleaning plate 31 and the cleaning brush 32 remain unchanged, which facilitates the detection camera 15 to move to the outside of the protective box 1 for detection.

[0033] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
