The invention discloses an automobile seat backrest supporting headrest structure, and relates to the field of automobile seat backrests, the automobile seat backrest supporting headrest structure comprises a backrest main body, and the bottom end of the backrest main body is rotatably connected with a seat main body. When a driver or a passenger adjusts the angle of the headrest, the angle of the headrest is adjusted by moving the control block, the control block slides smoothly in the movable hole, the trapezoidal section of the control block gradually increases oblique pressure on the movable rod, stable adjustment is ensured, the movable rod moves upwards to extrude the spring, the spring is compressed to store energy, meanwhile, the inserting block is pushed to leave the locking groove, the swing rod and the linkage rod are unlocked, and after unlocking, the angle of the headrest is adjusted. The swing rod and the linkage rod freely rotate, the headrest angle is easily adjusted to the optimal supporting position, after adjustment is completed, the control block is reset, the spring releases energy to push the movable rod and the insertion block to reset, the insertion block is accurately inserted into the locking groove, the headrest angle is stabilized, the control block is automatically reset in the process, and preparation is made for next adjustment. A locking mechanism ensures that the headrest is stable and does not shake, and riding safety and comfort are improved.
本发明公开了一种汽车座椅靠背支撑头枕结构,涉及汽车座椅靠背领域,包括靠背主体,所述靠背主体底端转动连接有座椅主体。本发明,司机或乘客调整头枕角度时,通过移动控制块实现,控制块在活动孔内顺滑滑动,其梯形切面渐增斜向压力于活动杆,确保调节平稳,活动杆上移挤压弹簧,弹簧压缩储能,同时推动插接块离开锁定槽,解锁摆动杆与联动杆,解锁后,摆动杆与联动杆自由转动,轻松调节头枕角度至最佳支撑位置,调节完成后,控制块复位,弹簧释放能量推动活动杆及插接块复位,插接块精准插入锁定槽,稳固头枕角度,此过程自动复位控制块,为下次调节做准备,锁定机制确保头枕稳定不晃动,提升乘车安全与舒适感。
