Currently, most headrest displays on the market are either fixed or electrically flip-up. However, fixed headrest displays have a fixed angle after installation and cannot be changed, affecting the user's viewing experience. Electrically flip-up headrest displays are expensive, have a risk of failure, and are difficult to maintain and costly to repair. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the existing technology and provide a vehicle display screen rotation device. The rotation shaft is inserted into the damping housing, and the resistance to the rotation shaft is adjusted by adjusting the number of damping plates, so that the vehicle display screen can be turned manually by rotating the rotation shaft, thus meeting different damping force requirements.

[0004] This utility model provides a vehicle-mounted display screen rotation device, including a fixed bracket, a damping assembly, and a rotating shaft; the damping assembly includes a damping housing and a plurality of damping plates; the damping housing is fixed to the fixed bracket; the damping housing has a through-hole for mounting, and the plurality of damping plates are detachably disposed in the through-hole; the rotating shaft is rotatably disposed in the through-hole, and both ends of the rotating shaft extend outside the through-hole and are used to fix it to the vehicle-mounted display screen; the damping plates abut against the rotating shaft.

[0005] This utility model embodiment provides a vehicle-mounted display screen rotation device. A fixed bracket is used to fix the device to the vehicle's mounting structure. A damping housing is fixed to the fixed bracket, and a through-hole is provided in the damping housing. The rotating shaft rotatably passes through the through-hole. When the rotating shaft rotates within the through-hole, it needs to overcome the friction of the damping plates. Therefore, the vehicle-mounted display screen can only be rotated manually. Several damping plates are detachably disposed in the through-hole. The resistance to the rotating shaft can be adjusted by removing the damping plates, thereby adjusting the number of damping plates according to the weight of different vehicle-mounted displays until the condition that the vehicle-mounted display screen will rotate only when manual force is applied is met. Both ends of the rotating shaft extend outside the through-hole and are used to fix it to the vehicle-mounted display screen. In this utility model embodiment, the rotating shaft is inserted into the damping housing, and the resistance to the rotating shaft is adjusted by adjusting the number of damping plates, so that the vehicle-mounted display screen can be rotated only when the rotating shaft is manually rotated, satisfying different damping force requirements.

[0006] Furthermore, a plurality of the damping plates are arranged side by side along the axial direction of the rotation shaft. The damping plates are detachably arranged to provide frictional force when the rotation shaft rotates, and the direction of the frictional force remains unchanged even after the number of damping plates is changed.

[0007] Furthermore, the damping housing has an assembly opening on its side that communicates with the mounting through hole, and the assembly opening extends axially along the rotating shaft; the damping plate is detachably disposed in the assembly opening; an arc-shaped clamping arm is provided on the side of the damping plate facing the rotating shaft, and the clamping arm and the inner wall of the damping housing form a clamping space surrounding the rotating shaft, and the clamping arm abuts against the rotating shaft; the damping plate has an engaging part on the side away from the rotating shaft that engages with the assembly opening.

The clamping arm and the inner wall of the damping housing form a clamping space surrounding the rotating shaft. The clamping arm abuts against the rotating shaft, so that the clamping arm can generate frictional force on the rotating shaft during rotation. The side of the damping plate away from the rotating shaft is provided with a locking part that engages with the assembly opening, so that the damping plate is firmly installed in the damping housing.

[0008] Furthermore, the damping housing includes an outer shell and an inner shell; the outer shell is fixed to the fixing bracket, and the inner shell extends into the outer shell; the inner shell has a through-hole. The outer shell is fixed to the fixing bracket, and the inner shell extends into the outer shell. The outer shell can be replaced according to different vehicle models.

The limiting notch is disposed at at least one end of the damping housing, the limiting notch extending axially along the rotation shaft, and the angle limiting member is disposed on the shaft at a position corresponding to the limiting notch, the angle limiting member having a protruding rotating portion located within the limiting notch; when the rotation shaft rotates, the rotating portion follows the rotation shaft and moves within the limiting notch, the limiting notch extending axially along the rotation shaft, and stops rotating when the rotating portion follows the rotation shaft to one end of the limiting notch.

[0011] Furthermore, one end of the rotating shaft has a shaving surface along its axial direction; the angle limiting member has a shaving fit hole extending through the rotating shaft along its axial direction, the angle limiting member engaging with the shaving surface through the shaving fit hole and being engaged with the rotating shaft. The shaving surface at one end of the rotating shaft forms a stepped structure with the rest of the rotating shaft, and the shaving fit hole extending through the rotating shaft allows the angle limiting member to engage with the shaving surface through the shaving fit hole and be engaged with the rotating shaft. This stepped structure prevents the rotating shaft from moving.

[0012] Furthermore, the vehicle-mounted display screen rotation device also includes a connecting bracket for fixing to the vehicle-mounted display screen; the connecting bracket is fixed to both ends of the rotating shaft extending outside the mounting through hole. The connecting bracket is fixed to both ends of the rotating shaft extending outside the mounting through hole, allowing the rotating shaft to be connected to the vehicle-mounted display screen to drive the vehicle-mounted display screen to rotate.
