The invention relates to a four-direction electric adjusting headrest structure and a using method thereof. The four-direction electric adjusting headrest structure comprises a front shell and a rear cover which are arranged front and back, a guide mechanism moving front and back is arranged between the front shell and the rear cover, a containing space is formed between the front shell and the rear cover, an insertion pipe penetrates into the containing space from bottom to top, and a lifting base is slidably installed on the insertion pipe located in the containing space; the lifting base is fixedly connected with the rear cover; a transmission mechanism is mounted in the lifting base; the front shell is fixedly provided with a transverse rack backwards penetrating through the lifting base, and further comprises a longitudinal rack fixedly connected with the insertion pipe; the transmission mechanism comprises a first gear and a second gear which are coaxially arranged, the first gear is meshed with the longitudinal rack, and the second gear is meshed with the transverse rack; the first gear rotates to move up and down relative to the longitudinal rack meshed with the first gear, and the transmission mechanism and the lifting base drive the rear cover and the front shell to move up and down; and the second gear rotates to enable the transverse rack meshed with the second gear to move back and forth to pull the front shell to move back and forth. Therefore, up-down and front-back four-direction adjustment of the headrest is achieved, layout is optimized, and use is convenient and reliable.

    本发明涉及一种四向电动调整头枕结构及其使用方法,包括前后布置的前壳和后盖,其间设置前后移动的导向机构,前壳和后盖之间构成容纳空间,从下向上穿至容纳空间内安装插管,位于容纳空间内的插管上滑动安装升降座,升降座与后盖固接,升降座内安装传动机构;前壳上固装向后贯穿升降座的横向齿条,还包括与插管固连的纵向齿条;传动机构中包括同轴设置的齿轮一和齿轮二,齿轮一与纵向齿条啮合,齿轮二与横向齿条啮合;齿轮一转动使其相对于与其啮合的纵向齿条上下移动,传动机构、升降座带动后盖、前壳上下移动;齿轮二转动使得与其啮合的横向齿条前后移动,拉动前壳前后移;从而实现了头枕的上下、前后四向调节,布局优化,使用方便可靠。
