The invention discloses a supporting device of an automobile headrest. The supporting device comprises a connecting frame and a pillow frame, the pillow frame is arranged on the connecting frame; a locking mechanism and a pillow frame resetting mechanism are arranged on the connecting frame; a transmission mechanism, a roller and a resetting mechanism of the roller are arranged on the connecting frame; a pull rope is wound on the circumference of the roller; one end of the pull rope is connected with the roller; the other end of the pull rope extends out of the connecting frame; one end of thetransmission mechanism is in linkage with the roller, the other end of the transmission mechanism is in linkage with the locking mechanism, when one end of the pull rope extending out of the connecting frame is pulled, the roller is driven by the pull rope to rotate, the roller can drive the locking mechanism to unlock the pillow frame through the transmission mechanism, and when no pull force isapplied on the pull rope, the resetting mechanism of the roller drives the roller to reversely rotate and reset. The supporting device has the advantages that the pull rope is prevented from being directly connected with a headrest rotation triggering structure, the joint of the pull rope and the pull rope tension transmission structure is stressed evenly, damage is not likely to happen, the service life is long, and therefore the service life of the supporting device is prolonged.
一种汽车头枕的支撑装置,包括连接架和枕架,枕架设置在连接架上,在连接架上设置有锁定机构以及枕架复位机构,在连接架上设置有传动机构、滚轮以及滚轮的复位机构,拉绳卷绕在滚轮的圆周上,拉绳的一端与滚轮相连接,拉绳的另一端伸出连接架,传动机构的一端与滚轮相联动,传动机构的另一端与锁定机构相联动,当拉动伸出连接架的拉绳一端时,拉绳拉动滚轮旋转,滚轮经传动机构带动锁定机构解锁枕架,当拉绳上无拉力时,滚轮的复位机构驱动滚轮反向旋转复位。本发明的优点在于:避免了拉绳与头枕转动触发结构直接相连接,使拉绳与拉绳拉力传动结构的连接处受力均匀,不易损坏,使用寿命长,从而延长本支撑装置的使用寿命。
