DETAILED DESCRIPTION

[0022] like Figures 1 to 7 As shown, the utility model relates to a film and television playback device, including a car seat 1, a seat rod 2 is fixedly sleeved in an upper hole of the car seat 1, a bracket 3 is clamped on the outer wall of the seat rod 2, and protective mechanisms 4 are arranged on both sides of the bracket 3; the protective mechanism 4 includes a trigger unit 5 and a deflation unit 6; a placement unit 7 is arranged on one side of the bracket 3; the protective mechanism 4 includes an ejection slot 401, the ejection slots 401 are respectively opened on both sides of the car seat 1, and air bags 402 are respectively arranged inside the two ejection slots 401, a connecting plate 403 is clamped on the inner wall of each ejection slot 401, and a decomposition slot 403a is opened on one side of the connecting plate 403.

[0023] In the embodiment of the utility model, the trigger unit 5 includes a mixing cylinder 501, the mixing cylinder 501 is fixedly connected to the other side of the bracket 3, the inner wall of the mixing cylinder 501 is fixedly sleeved with a partition 501a, the inner wall of the partition 501a is clamped with a mixing disk 502, and a plurality of iron balls 502a are arranged in the mixing disk 502. The side surface of the mixing cylinder 501 is symmetrically structured and fixedly connected with an air delivery pipe 503, and the air delivery pipe 503 is fixedly connected with the air bag 402. The deflation unit 6 includes a through hole 601, and the through hole 601 Opened on both sides of the bracket 3, the inner wall of the through hole 601 is fixedly sleeved with a protective ring 602, the inner wall of the protective ring 602 is fixedly connected with a support plate 603, the inner wall of the support plate 603 is movably sleeved with a spring 604, the inner wall of the protective ring 602 is fixedly sleeved with an annular disk 605, the inner wall of the annular disk 605 is clamped with a rubber disk 606, one side of the rubber disk 606 is fixedly connected with a button 607 and the button 607 is movably sleeved inside the protective ring 602. When a car collides while driving, the car will be hit. The inertia generated causes the iron ball 502a in the mixing disk 502 to collide forward, exerting a thrust on the mixing disk 502, causing the mixing disk 502 to pop out from the partition 501a, causing a chemical mixing reaction to generate gas in the mixing cylinder 501, and the generated gas flows into the airbag 402 from the gas pipe 503. During the expansion of the airbag 402, the pressure of the airbag 402 in the ejection slot 401 increases, causing the connecting plate 403 to pop out through the decomposition slot 403a and decompose. 402 also pops out and is ejected onto the display 8, which can protect the head of the rear seat passenger. After protecting the passenger's head, the air in the car is reduced due to the ejection of the airbag 402. By pressing the protective ring 602 inside the protective ring 602, the rubber disk 606 is ejected from the annular disk 605, and the annular disk 605 is ejected into the support plate 603. Since the protective ring 602 is fixedly connected to the airbag 402, the gas in the airbag 402 is completely discharged to the outside, thereby increasing the oxygen in the air in the car.

[0024] In an embodiment of the utility model, the placement unit 7 includes a slide groove 701, which is opened on one side of the bracket 3. A tension spring 702 is movably sleeved in the slide groove 701, and one end of the tension spring 702 is fixedly connected to a baffle 703. A display 8 is provided on one side of the bracket 3. When the rear seat passengers need to use the display 8 while the car is driving, they pull the baffle 703 upward to increase the placement space, and then place the display 8 in the bracket 3. Through the elastic deformation function of the tension spring 702 itself, the baffle 703 pushes the display 8, so that the display 8 can be fixed on the bracket 3.

[0025] Working principle: This embodiment provides a video playback device. When the rear seat passenger needs to use the display 8 while the car is driving, he first pulls the baffle 703 upward to increase the placement space, and then puts the display 8 in the bracket 3. Through the elastic deformation function of the tension spring 702 itself, the baffle 703 pushes the display 8, and the display 8 can be fixed on the bracket 3. When the car collides while driving, the inertia generated by the car when it is hit makes the iron ball 502a in the mixing disk 502 collide forward, pushing the mixing disk 502, so that the mixing disk 502 pops out from the partition 501a, so that the chemical mixture in the mixing cylinder 501 generates gas, and the generated gas is discharged from the gas pipe 503. The air flows into the airbag 402. During the expansion of the airbag 402, the pressure of the airbag 402 in the ejection slot 401 increases, causing the connecting plate 403 to eject outward through the decomposition slot 403a and decompose. The airbag 402 is also ejected and ejected onto the display 8, which can protect the heads of the rear seat passengers. After protecting the heads of the passengers, the air in the car is reduced due to the ejection of the airbag 402. By pressing the protective ring 602 inside the protective ring 602, the rubber disk 606 is ejected from the annular disk 605, and the annular disk 605 is ejected into the support plate 603. Since the protective ring 602 is fixedly connected to the airbag 402, the gas in the airbag 402 is completely discharged to the outside, thereby increasing the oxygen in the air in the car.

[0026] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
