[0034] The following is combined with Figure 1-9 This application is described in further detail.
[0035] The embodiment of the present application discloses a vehicle-mounted rear entertainment screen with an integrated mechanism for flipping and moving forward and backward. Figure 1 , Figure 2 and Figure 3 , including a guide rail 1, in which a driving slider 2 and a rear slider 3 are slidably connected, the driving slider 2 is driven by a single motor, and the single motor drives the flexible shaft, so that the driving slider 2 can slide along the length direction of the guide rail 1; a limit connecting rod 4 is arranged between the driving slider 2 and the rear slider 3, the limit connecting rod 4 includes a main body 41 and an extended end 42, the main body 41 is arranged at one end close to the driving slider 2, a limit slot 21 is provided on the surface of the driving slider 2, and a limit block 411 is arranged at one end of the main body 41 close to the limit slot 21, and the limit block 411 is pressed into the limit slot 21, thereby pushing the limit connecting rod 4 to slide.
[0036] Reference Figure 2 and Figure 3The extended end 42 is slidably connected in the body 41, and the other end of the extended end 42 is rotatably connected to the rear slider 3. When the driving slider 2 slides, it will drive the limit link 4 and the rear slider 3 to slide together; the outer wall of the driving slider 2 is provided with a first rotating pin 22, and the outer wall of the rear slider 3 is provided with a second rotating pin 31. The first rotating pin 22 is rotatably connected to a screen bracket 5 for installing an entertainment screen, and the second rotating pin 31 is rotatably connected to a rotating arm 6, and one end of the rotating arm 6 away from the second rotating pin 31 is rotatably connected to the side wall of the screen bracket 5.
[0037] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 A positioning block 7 is provided in the guide rail 1. The positioning block 7 is located in the movement direction of the driving slider 2. A limiting groove 71 is provided on the bottom wall of the positioning block 7. The height of the top wall of the limiting block 411 is higher than the height of the bottom wall of the positioning block 7. In the process of the limiting link 4 sliding with the driving slider 2, the limiting block 411 will enter the limiting groove 71. Since the positioning block 7 is fixed, the continued movement of the limiting link 4 and the rear slider 3 will be limited, and the protrusion will also be separated from the limiting groove 21 and continue to move against the bottom wall of the limiting link 4. In the process of the driving slider 2 continuing to move, the screen bracket 5 and the rotating arm 6 will rotate toward each other, thereby realizing the flipping of the entertainment screen. In this embodiment, the extension end 42 is rotatably connected to the second rotating pin 31 to prevent the limiting link 4 from breaking due to deformation.
[0038] Reference Figure 1 and Figure 2 When the driving slider 2 moves to the side wall of the rear slider 3, the screen bracket 5 rotates to the maximum amplitude. At this time, the driving slider 2 continues to move, which will drive the rear slider 3 and the extension end 42 to continue to move along the length direction of the guide rail 1. An elastic member 43 is arranged on the outer wall of the main body 41. In this embodiment, the elastic member 43 adopts a spring. The elastic member 43 is arranged along the length direction of the main body 41. One end of the elastic member 43 is connected to the main body 41, and the other end is connected to the extension end 42 to provide elastic force after the extension end 42 moves relative to the main body 41, so as to facilitate the subsequent resetting of the extension end 42; a limiting tube 44 is also provided on the outer wall of the main body 41, and the limiting tube 44 is sleeved on the outside of the elastic member 43 to prevent the elastic member 43 from offsetting, resulting in the problem that the extension end 42 and the main body 41 cannot be reset.
[0039] Reference Figure 2 and Figure 3 A reset torsion spring 8 is sleeved around the peripheral wall of the second rotating pin 31. One end of the reset torsion spring 8 is connected to the guide rail 1 by gluing, and the other end of the reset torsion spring is connected to the second rotating pin 31 by gluing. The reset torsion spring 8 provides elastic potential energy so that the rotating arm 6 can be reset.
[0040] Reference Figure 2 , Figure 6, Figure 7 , Figure 8 and Fig. 9 A limiter 9 is also provided on the second rotating pin 31, and a bracket 91 is provided at one end of the limiter 9 to support the rear end of the screen bracket 5. A hook ear 92 is provided at one end of the bracket 91 to abut against the side wall of the rear end of the screen bracket 5 to maintain the stability of the screen bracket 5; a tongue edge 93 is provided on the limiter 9, and a stabilizing groove 11 for the tongue edge 93 to abut against is provided on the guide rail 1. When the entertainment screen is not opened, the tongue edge 93 is embedded in the stabilizing groove 11. At this time, the hook ear 92 will abut against the side wall of the rear end of the screen bracket 5 to ensure that the screen bracket 5 maintains stability in the unopened state.
[0041] The implementation principle of the integrated flipping and forward and backward moving mechanism of the vehicle rear entertainment screen in the embodiment of the present application is as follows: the motor drives the flexible shaft to make the driving slider 2 slide in the guide rail 1, and the driving slider 2 drives the limiting connecting rod 4 and the rear slider 3 to move together through the limiting card slot 21 and the limiting block 411, thereby driving the entertainment screen fixed on the screen bracket 5 to move forward and backward; when the limiting block 411 moves to the positioning block 7, the limiting block 411 will be pressed into the limiting groove 71 of the positioning block 7, thereby making it impossible for the limiting connecting rod 4 and the rear slider 3 to continue to move with the driving slider 2. In the process of the driving slider 2 continuing to move, the first rotating pin 22 and the second rotating pin 31, the screen bracket 5 and the rotating arm 6 will rotate towards each other, thereby realizing the flipping of the screen bracket 5 and the entertainment screen installed on the screen bracket 5; after the screen bracket 5 completes the flipping, the driving slider 2 continues to move, thereby driving the rear slider 3 and the extension end 42 to move relative to the main body 41, thereby adjusting the distance of the entertainment screen; the mechanism of the present application does not need to adopt multiple motors, only one motor is needed to drive the driving slider 2 to slide along the length direction of the guide rail 1 to complete the movement and flipping of the entertainment screen, the structure is simple, can effectively save the space in the car, reduce the cost, and has high practicality and economic benefits.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
