Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. An automobile headrest with an electric adjusting lug plate is shown in figure 1 and comprises a front cover 1 and a rear cover 2, wherein the front cover 1 comprises a middle cover 15, lug plates 16 which are connected in a rotating mode are arranged on two sides of the middle cover 15, a front concave portion 17 is arranged on the front side of the rear cover 2, and a sliding block mechanism 18 capable of driving the lug plates 16 to overturn is arranged in the front concave portion 17. The utility model discloses it is fixed with the back of car seat with the back lid during the installation.

As shown in fig. 2, the contents of another part of the slider mechanism 18 symmetrically distributed about the front motor 20 are omitted for enlarging the details of the drawing. The slider mechanism 18 include the mounting panel 19 of U type, be fixed with leading motor 20 on the mounting panel 19, be equipped with second lead screw 21 on the leading motor 20, the screw thread turning at second lead screw 21 both ends is opposite, the both sides of mounting panel 19 all are equipped with slide rail 22, the top of slide rail 22 is equipped with the runing rest 23 who fixes mutually with auricle 16, be equipped with between runing rest 23 and the slide rail 22 with one section threaded connection's of second lead screw 21 slider 24, be equipped with application of force pole 25 between runing rest 23 and the slider 24, the both ends of application of force pole 25 all are articulated with runing rest 23 and slider 24 respectively through the rivet, runing rest 23 passes through connecting rod 26 and slide rail 22 rotation connection.
