The invention discloses a vehicle-mounted ceiling television transmission device which comprises a ceiling, an LED screen and a pair of transmission hinge sets. The transmission hinge set comprises a gearbox, a first motor, a hinge part and a movable piece. The gearbox is fixed on the ceiling, and the first motor is in meshed connection with the gearbox through a transmission gear; the hinging part comprises a gear shaft, an elastic piece and a fastening piece; one end of the gear shaft is meshed with the gearbox; the movable sheet comprises a first fixed sheet and a second fixed sheet which are perpendicular to each other; the first fixing sheet is connected with the LED screen; the second fixing sheet is sleeved on the gear shaft; the elastic piece is located between the second fixing piece and the fastening piece, and the fastening piece is used for pressing the second fixing piece on the gear shaft. According to the invention, the fastening piece and the elastic piece are pressed, and the friction force between the elastic piece and the movable piece is adjusted to be greater than the gravity of the LED screen, so that the LED screen can be manually adjusted and can be maintained at any angle, and the effect of manually adjusting the angle is realized.

    本发明公开一种车载吸顶电视传动装置,包括顶棚、LED屏幕以及一对传动铰链组;传动铰链组包括变速箱、第一马达、铰接部与活动片;变速箱固定于顶棚上,第一马达通过传动齿轮与变速箱啮合连接;铰接部包括齿轮轴、弹性件与紧固件;齿轮轴的一端与变速箱啮合;活动片包括相垂直的第一固定片与第二固定片;第一固定片与LED屏幕连接;第二固定片套设于齿轮轴上;弹性件位于第二固定片与紧固件之间,紧固件用于将第二固定片压合在齿轮轴上。本发明通过紧固件与弹性件来压合,通过调节弹性件与活动片的摩擦力,使该摩擦力大于LED屏幕的自身重力,从而可手动调节LED屏幕并使该屏幕可维持在任意角度,实现了手动调节角度的效果。
