The invention provides an automobile safety belt pre-tightening end sheet and an automobile. The pre-tightening end sheet comprises a steel wire rope, an elastic sheet clamping base, a piston connecting rod and a steel pipe, wherein the elastic sheet clamping base is sleeved on the piston connecting rod, clamping jaws are arranged in the circumferential direction of the elastic sheet clamping baseand can elastically deform in the radial direction of the elastic piece clamping base, the piston connecting rod sleeves the steel wire rope and can drive the steel wire rope to move in the cavity ofthe steel pipe so as to achieve the pre-tightening action, a clamping groove is formed in the inner wall of the steel pipe, the elastic sheet clamping base can move along with the piston connecting rod, and the clamping jaw is clamped in the clamping groove, so that the movement of the piston connecting rod in a single direction is limited. According to the scheme, machining is convenient, assembling is easy, practicability is high, reliability is high, high axial force resistance is achieved, the locking performance of the pre-tightening end sheet is improved, and then the safe driving performance of an automobile is improved.

    发明提供一种汽车安全带预紧端片及汽车,该预紧端片包括钢丝绳、弹片卡座、活塞连杆以及钢管;弹片卡座套设于活塞连杆上;弹片卡座的周向上设有卡爪,卡爪能够沿弹片卡座的径向发生弹性形变;活塞连杆套设于钢丝绳上,并能够带动钢丝绳在钢管的腔体内移动,从而实现预紧动作;钢管的内壁上设有卡槽;弹片卡座能够随活塞连杆一起移动,并使卡爪卡接在卡槽内,从而限制活塞连杆在单一方向的移动;本发明提供的方案,加工方便、装配简单、实用性强、可靠性高,具有很强的抗轴向力能力,同时提高预紧端片的锁止性能,进而提高汽车安全驾驶性能。
