The invention relates to an automobile armrest hinge assembly. Comprising a hinge lower support, a hinge upper rotating arm, a hinge shaft, a first damper cover plate, a second damper cover plate and a shaft sleeve, wherein the hinge shaft is connected with the hinge lower support and the hinge upper rotating arm; the first damper cover plate and the second damper cover plate are arranged on the hinge shaft and on the two sides of the hinge lower support; the shaft sleeve is arranged between the hinge lower support and the hinge shaft; the hinge upper rotating arm is in interference rotating connection with a straight knurling area on the hinge shaft, an upper shaft hole of the shaft sleeve is in interference and friction fit with the hinge shaft, the shaft sleeve is in transition fit connection with the hinge lower support, and the first damper cover plate is arranged on the hinge lower support. And the rotating resistance between the hinge shaft and the hinge upper rotating arm is smaller than the resistance between the hinge shaft and the shaft sleeve. Compared with the prior art, the hinge is simple in structure and capable of being produced in batches, and the purpose that the rotating arm on the hinge can be fixed at any position when the rotating arm rotates to be opened and closed is achieved.
