The invention provides an automobile seat headrest circuit plug-in structure which comprises a headrest rod, a fixed guide sleeve fixed on a backrest framework and a headrest guide sleeve mounted in the fixed guide sleeve, a headrest rod connecting terminal is mounted at a bottom end opening of the headrest rod, a first magnetic ring and a first circuit contact are arranged on the headrest rod connecting terminal, and a second magnetic ring and a second circuit contact are arranged on the headrest rod connecting terminal. The plug is fixed below the fixed guide sleeve in a magnetic attraction mode and located on the advancing route of the headrest rod, a second magnetic ring and a second circuit contact are arranged on the plug, and when the headrest rod is inserted into the headrest guide sleeve and located at the using position, the first magnetic ring is connected with the second magnetic ring in a magnetic attraction mode, and the first circuit contact is in contact with the second circuit contact. When the height of the headrest rod is adjusted up and down within the use position range, the plug is separated from the fixed guide sleeve, and the headrest rod can drive the plug to move up and down together. The device is simple in structure and small in size, and rapid power-on and power-off of a headrest circuit and a seat circuit can be achieved when the headrest rods are disassembled and assembled.
本发明提出了一种汽车座椅头枕电路插接结构,包括头枕杆、固定于靠背骨架上的固定导套和安装于固定导套内的头枕导套,头枕杆连接端子安装于头枕杆的底端开口处,头枕杆连接端子上设有第一磁环和第一电路触点,插头磁吸固定于固定导套下方,且位于头枕杆的行进路线上,插头上设有第二磁环和第二电路触点,当头枕杆插入头枕导套内,并处于使用位置时,第一磁环与第二磁环磁吸相接,第一电路触点与第二电路触点接触,使得头枕杆连接端子与插头处于电路连通状态,当头枕杆在使用位置范围内进行上下高度调节时,插头与固定导套分离,头枕杆能带动插头一同上下移动。本发明结构简单,体积较小,在头枕杆拆装时能实现头枕电路与座椅电路的快速通断电。
