The invention discloses a force limiting device of a lock catch. The force limiting device comprises a support, a mandrel, a torsion bar and a connecting rope. The support is fixed to a vehicle body component, the two ends of the mandrel are rotatably supported on the support, the torsion bar is coaxially arranged in the mandrel and comprises a first part fixed to the support and a second part capable of synchronously rotating with the mandrel, the connecting rope is used for connecting the lock catch and the mandrel, and a hook assembly is arranged on the mandrel; the connecting rope comprises a first folding end and two linear sections extending out of the first folding end, the first folding end is fixed to the hook assembly, and the two linear sections extend out of the interior of the first folding end to be fixedly connected with the lock catch after being wound around the peripheral face of the mandrel. Large-area machining of the mandrel is not needed, a connecting piece does not need to be arranged on the connecting rope in advance, and the problems that in the prior art, the structure between the mandrel and the steel wire rope is complex, and machining difficulty is high are solved.

    本发明公开了一种锁扣的限力装置,包括支架、芯轴、扭力杆和连接绳;支架固定在车身部件上,芯轴两端被可旋转地支撑在支架上,扭力杆同轴地设置于芯轴内部,且扭力杆包括被固定在支架的第一部分和可与芯轴同步旋转的第二部分,连接绳用于连接锁扣和芯轴,芯轴上设置有钩组件;连接绳包括第一对折端和从第一对折端伸出的两线型段,第一对折端固定在钩组件上,且两线型段缠绕于芯轴的外周面后从第一对折端内部伸出与锁扣固定连接。本发明无需对芯轴进行大面积加工,也无需在连接绳上预设连接件,解决了现有技术中芯轴和钢丝绳之间结构复杂,加工难度高的问题。
