The invention discloses an electric headrest folding mechanism which comprises a mounting support and a headrest support, and linear sliding grooves and curve sliding grooves are formed in the left side wall and the right side wall of the mounting support; each curve sliding groove comprises an arc-shaped guiding section and a straight buffering section, the arc-shaped buffering sections are close to the linear sliding grooves, cross rods are arranged in the curve sliding grooves in the left side wall and the right side wall of the mounting support in a penetrating mode, sliding pieces are arranged in the linear sliding grooves in the left side wall and the right side wall of the mounting support in a penetrating mode, and the sliding pieces are driven by a motor to move. A connecting rod is hinged between the cross rod and the sliding piece; the headrest support is connected with the transverse rod, and the transverse rod moves in the curve sliding groove and can drive the headrest support to be folded. The headrest folding mechanism has the advantages that the structure is simple, manufacturing is convenient, concentric rotation is adopted in the headrest folding mechanism, and the shape adaptability is high; the curve sliding groove can enable the headrest to be locked stably, the impact resistance is high, the structure is compact, the size is small, platformization is easy to achieve, and the mechanism universality is high.

    本发明公开了一种电动头枕翻折机构,包括安装支架和头枕支架,其中在所述安装支架的左右两侧壁上均设置有直线滑槽和曲线滑槽;所述曲线滑槽包括弧形导向段和平直缓冲段,其中弧形缓冲段靠近直线滑槽,在安装支架的左右两侧壁的曲线滑槽内穿设有横杆,在所述安装支架的左右两侧壁的直线滑槽内穿设有滑动件,所述滑动件通过电机驱动移动,在所述横杆和滑动件之间铰接有连杆;所述头枕支架与所述横杆连接,所述横杆在曲线滑槽内移动能够带动头枕支架翻折。本发明的有益效果:结构简单,制造方便,该头枕折叠机构采用同心旋转,造型适应性高;其中的曲线滑槽可使头枕锁止稳定,抗冲击能力强,结构紧凑体积小,易于实现平台化,机构通用性强。
