[0021] The specific implementation of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown, the manual rotating screen bracket structure includes a fixed bracket 2 for connecting to the vehicle body and a rotating bracket 4 for fixing the display screen. The rotating bracket and the fixed bracket are rotatably connected through a rotating main shaft 6. A bushing 3 is provided on the rotating bracket, and a group of damping plates 5 that can increase or decrease the damping size are provided in the bushing. The rotating main shaft and the group of damping plates are interference fit.

[0023] A limiting structure for limiting the rotation angle is provided between the rotating bracket and the fixed bracket; preferably, the limiting structure includes an arc-shaped limiting groove provided on the fixed bracket and a limiting pin provided on the rotating bracket, and the end of the limiting pin is located in the limiting groove.

[0024] Furthermore, both the fixed bracket and the rotating bracket are provided with a rotation matching plane, and the limiting structure is arranged at the matching plane, so that the operation is stable and reliable.

[0025] The rotating main shaft and the fixed bracket are fixedly connected, and the damping plate and the rotating main shaft are both metal structures; a protrusion is provided on the outer edge of the damping plate, and a groove adapted to the protrusion is provided in the bushing.

[0026] The manual rotating screen bracket of the utility model has a reasonable structural design, the damping torque can be adjusted according to demand, the damping torque is stable, and the attenuation during the life cycle is less than 15%; the damping plate and the bushing structure are integrated, the structure is compact, the space is small, and it is easy to arrange and install.

[0029] A bushing is fixed on each of the fixed bracket and the rotating bracket. The two bushings are made of wear-resistant material and are used for the direct contact surface of the two brackets; the damping plate is fixed in the hole of the rotating bracket and cannot rotate with the optional bracket; the damping plate is assembled on the rotating spindle through an interference fit, and the rotating spindle passes through the rotating bracket and the fixed bracket; the fixing screw 1 is locked on the rotating spindle (there is a threaded hole on the spindle), so that the two brackets are connected through the rotating spindle, and the spindle is connected to the fixed bracket together.

[0030] When the swivel bracket rotates, the damping plate and the rotating spindle rotate to provide sufficient rotational torque. By adjusting the number of damping plates, the torque of the entire optional mechanism can be adjusted. The damping plates and the optional spindle are both made of wear-resistant metal to ensure the stability of the damping. The rotation angle of this mechanism can be set by using the upper limit pin on the swivel bracket and the limit slot on the fixed bracket.
