The invention discloses an electronic actuator for adjusting an automobile headrest, and the electronic actuator comprises a driving assembly which comprises a driving part, a first transmission part, a second transmission part and a driving screw rod, and one end of the driving screw rod is connected to a seat; a connecting groove is formed in the upper shell; a placement groove and a containing part are formed in the lower shell, the interior of the placement groove is used for fixing the driving assembly and is combined with the connecting groove to form a sealing cavity, the driving end of the driving part is connected with the first transmission part and is connected with the second transmission part through the first transmission part, and the second transmission part is connected with the driving lead screw in a sleeving mode. The headrest connected with the lower shell is driven to ascend and descend in the vertical direction, the containing parts are arranged on the inner walls of the two sides of the lower shell, and the two ends of the first transmission part are connected into the corresponding containing parts through oil bearings respectively. The power torque is increased, the smoothness of the headrest during lifting is improved, and the situation that the headrest is difficult to drive due to the fact that the headrest pressing resistance of the head is large is avoided.

    本发明公开了一种调节汽车头枕的电子执行器,包括:驱动组件,驱动组件包括驱动部、第一传递部、第二传递部和驱动丝杆,驱动丝杆的一端连接在座椅上;上壳体,上壳体内开设有连接槽;下壳体,下壳体内开设有放置槽和容纳部,放置槽内用于固定驱动组件并和连接槽结合形成密封腔,驱动部的驱动端连接第一传递部,并通过第一传递部连接第二传递部,第二传递部套接驱动丝杆,在对接后,驱动连接下壳体的头枕在竖直方向升降,容纳部设置在下壳体两侧内壁上,第一传递部的两端通过含油轴承分别连接在对应的容纳部内。提升动力力矩,提升头枕在升降时的流畅性,避免头枕因为头部的枕压阻力较大,导致驱动困难。
