The mounting base 2 is penetrated with a plurality of vehicle body mounting fixing holes 24 for screws to pass through to connect the mounting base 2 to the vehicle body; the mounting base 2 is penetrated with a center hole 21 along the thickness direction, one end of the rotating base 3 passes through the center hole 21, the rotating base 3 is rotatably connected to the mounting base 2, and a screen connecting bracket 7 is provided on one side of the rotating base 3 passing through the center hole 21, and the screen connecting bracket 7 is connected to the vehicle-mounted central control entertainment screen 1.
[0032] Reference Figure 1 , Figure 2 and Figure 3 Two limiting grooves 22 are formed through the mounting base 2 along the thickness direction. The two limiting grooves 22 are symmetrically arranged about the axis of the center hole 21. The limiting grooves 22 are formed along the rotation direction of the rotating base 3. Two connecting pieces 33 are integrally formed on the side wall of the rotating base 3 corresponding to the limiting grooves 22. A connecting column 34 is integrally formed on the surface of the connecting piece 33 facing the limiting groove 22. The connecting column 34 passes through the limiting groove 22 and is fixed to the screen connecting bracket 7 by welding to drive the screen connecting bracket 7 and the entertainment screen 1 to rotate.
[0033] Reference Figure 2 and Figure 3A convex ring 23 is integrally formed around the center hole 21, and two clips 35 are integrally formed on the side wall of the rotating base 3. The end of the clip 35 away from the rotating base 3 is bent toward the convex ring 23, and the inner wall of the bent part of the clip 35 abuts against the outer wall of the convex ring 23, thereby ensuring the stability of the rotating base 3 when it rotates relative to the mounting base 2.
[0034] Reference Figure 1 , Figure 3 and Figure 4 A driving cavity 31 is provided at one end of the rotating base 3 away from the mounting base 2, and a rotating nut 5 is coaxially arranged in the driving cavity 31; the motor bracket 6 is connected to the side of the mounting base 2 away from the entertainment screen 1 by welding, and the motor bracket 6 is frame-shaped and nested in the outside of the rotating base 3. Two arc blocks 63 are integrally formed on the side of the motor bracket 6 facing the driving cavity 31. The arc block 63 takes the rotation axis of the rotating base 3 as the axis, and the arc block 63 is against the inner wall of the driving cavity 31 to improve the stability of the rotating base 3 during rotation; a through hole 61 is provided on the side of the motor bracket 6 facing the driving cavity 31, and the through hole 61 is coaxially arranged with the driving cavity 31. One end of the transmission screw 4 passes through the through hole 61 and is inserted into the driving cavity 31, and the rotating nut 5 is threadedly connected to the outer wall of the transmission screw 4, and a gear 41 is provided at the other end of the transmission screw 4 for meshing with the gear 41 on the motor output shaft for transmission.
[0035] Reference Figure 2 and Figure 3 The two limiting rods 51 are integrally formed with the side wall of the rotating nut 5, and the two limiting rods 51 are symmetrically arranged about the rotating nut 5. The side wall of the rotating base 3 is penetrated with a rotating base track groove 32 for the limiting rod 51 to pass through. The rotating base track groove 32 is arc-shaped and extends from the mounting base 2 toward the direction of the motor bracket 6; the side wall of the motor bracket 6 facing the limiting rod 51 is penetrated with a motor bracket track groove 62, and one end of the limiting rod 51 passing through the motor bracket track groove 62 is connected to the limiting block 52 by welding, and the limiting block 52 cannot pass through the motor bracket track groove 62, thereby being able to limit the rotating nut 5 when the transmission screw 4 rotates, so that the rotating nut 5 can move on the transmission screw 4, and the rotating base 3 is driven to rotate through the abutment relationship between the limiting rod 51 and the inner wall of the rotating base track groove 32. In this embodiment, both ends of the rotating base track groove 32 are provided with linear grooves 321 to achieve self-locking during 90° rotation and improve the fault tolerance of the motor.
[0036] The implementation principle of the rotating structure of a vehicle-mounted central control entertainment screen in an embodiment of the present application is as follows: when the motor drives the transmission screw 4 to rotate, the transmission screw 4 is threadedly matched with the rotating nut 5, and the limiting rod 51 is restricted by the motor bracket trajectory groove 62, so that the rotating nut 5 can move along the transmission screw 4, and at the same time, the limiting rod 51 moves along the motor bracket trajectory groove 62. Since the rotating base trajectory groove 32 is an arc groove, the rotating base 3 is driven to rotate through the abutment between the limiting rod 51 and the inner wall of the rotating base trajectory groove 32, so that the rotating base 3 can drive the entertainment screen 1 to rotate.
[0037] 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.
