Embodiment Construction

[0027] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0028] Such as figure 1 As shown, the car seat is equipped with an electric headrest adjustment mechanism according to a preferred embodiment of the present invention, and the headrest moves from a high position to a middle position and then to a low position sequentially by means of the electric headrest adjustment mechanism. The electric headrest adjustment mechanism includes a drive assembly 1, a bracket assembly 2 and a screw rod 3, wherein the drive assembly 1 is fixedly connected to the backrest frame, and the bracket assembly 2 is fixedly connected to the headrest guide rod, with The screw rod 3 of the longitudinal axis V is connected between the drive assembly 1 and the support assembly 2 so that the drive assembly 1 drives the movement of the support assembly 2 along the longitudinal axis V, thereby driving the adjustment of the headrest. ...

Abstract

The invention relates to an electric headrest adjusting mechanism. The mechanism comprises a driving assembly is fixedly connected to a backrest, a support assembly fixedly connected to a headrest, and a lead screw provided with a longitudinal shaft. The lead screw is connected between the driving assembly and the supporting assembly so as to drive the supporting assembly to move along the longitudinal axis through the driving assembly. The supporting assembly comprises a cross beam fixedly connected to the headrest and further comprises a first nut installed in the cross beam through a damping structure, and the lead screw is matched with the first nut to achieve linear motion of the first nut along the longitudinal axis. According to the electric headrest adjusting mechanism, by means ofthe damping structure, the lead screw is installed in a floating mode, shock absorption and energy absorption can be achieved, and the situation that in the prior art, the lead screw is clamped and stagnated can be avoided. Moreover, according to the electric headrest adjusting mechanism, the number of parts is small, and the structure is simple.

Description

technical field [0001] The present invention relates to a car seat, and more particularly relates to an electric headrest adjustment mechanism. Background technique [0002] Car seats with electrically adjustable head restraints are known. Usually, the seat back is fixed with a motor for driving the screw mandrel to rotate, and the nut fixedly connected to the headrest is sleeved on the screw mandrel to realize the up and down adjustment of the headrest by driving the nut up and down on the screw mandrel. Practice has shown that the existing corresponding adjustment mechanism is prone to the phenomenon of screw rod sticking. Contents of the invention [0003] In order to solve the situation that the screw rod is stuck in the adjustment mechanism in the prior art, the present invention provides an electric headrest adjustment mechanism. [0004] The electric headrest adjustment mechanism of the present invention includes a drive assembly fixedly connected to the backrest,...
