The invention relates to the technical field of vehicle seats, in particular to a crank sliding block self-locking mechanism and an electric rotating seat self-locking device. The slider-crank self-locking mechanism comprises a base body, a sliding body, a slider-crank mechanism and an adjusting mechanism, and the base body is fixedly arranged; the sliding body is in sliding connection with the base body; the crank sliding block mechanism comprises a sliding block, a connecting rod and a crank, the connecting rod is connected with the sliding body, the connecting rod is a reducing connecting rod, the crank is connected with the base body, and the sliding block is arranged between the sliding body and the base body; the adjusting mechanism is used for adjusting the length of the variable-diameter connecting rod, and when the sliding body slides to a set position, the crank sliding block mechanism is located at a dead point position. The connecting rod of the crank sliding block mechanism is arranged to be the variable-diameter connecting rod, reducing of the connecting rod in the rotating process is achieved, and therefore when the base sliding body slides to the set position, the connecting rod is not prone to falling off; the crank sliding block mechanism is located at the dead point position, self-locking is achieved, the self-locking position is flexible, and applicability is better.

    本发明涉及车辆座椅技术领域,特别涉及一种曲柄滑块自锁机构和电动旋转座椅自锁装置。曲柄滑块自锁机构包括基体、滑动体、曲柄滑块机构和调整机构,基体固定设置;滑动体与基体滑动连接;曲柄滑块机构包括滑块、连杆和曲柄,连杆与滑动体连接,连杆为变径连杆,曲柄与基体连接,滑块设置在滑动体与基体之间;调整机构用于调整变径连杆长度,且当滑动体滑动至设定位置时,曲柄滑块机构处于死点位置,本发明通过将曲柄滑块机构的连杆设置为变径连杆,实现连杆在转动过程中的变径,从而能够实现座滑动体滑动至设定位置时,曲柄滑块机构处于死点位置,实现自锁,自锁位置灵活,适用性更好。
