The invention relates to an electric headrest front-back adjusting device, a seat and a model car. The electric headrest front-back adjusting device comprises a rack, a gear, a rack and a headrest mounting plate. The gear is configured to be rotatably arranged on the rack; the rack is meshed with the gear, and the rack is driven by the gear to do linear motion; the headrest mounting plate is connected with the rack, and the headrest mounting plate is driven by the rack to do linear motion. The gear is meshed with the rack to drive the headrest mounting plate to do linear motion, the structure is simple, the connecting modes of a plurality of parts are few, and therefore the requirement for machining and mounting precision is low, and the stability of front-back adjustment of the headrest can be guaranteed.
本发明涉及一种电动头枕前后调节装置、座椅及模型车,电动头枕前后调节装置包括机架、齿轮、齿条和头枕安装板;齿轮被配置为可旋转的设置于所述机架上;齿条啮合所述齿轮,在所述齿轮的带动下,所述齿条做直线运动;头枕安装板连接所述齿条,在所述齿条的带动下,所述头枕安装板做直线运动。本发明通过齿轮啮合齿条带动头枕安装板做直线运动,结构简单,多个零件之间的连接方式较少,因而对加工和安装精度要求较低,能够保证头枕前后调节的稳定性。
