The invention relates to the field of pressing unlocking mechanisms, in particular to a heat knife unlocking mechanism, an installation method and a satellite. The hot knife unlocking mechanism comprises a first device used for being fixedly connected with a first component; the second device is used for being fixedly connected with a second component; the rope is wound outside the first device and the second device and locks the first device and the second device; and the hot knife assembly is slidably connected with the first device, abuts against the inner side of the rope and is used for heating and fusing the rope. The first component and the second component are locked through rope locking. By means of the first device, the hot knife assembly can slide on the first device, the hot knife assembly can move outwards from the inner side of the rope, the rope is heated and fused to achieve unlocking, impact force is small in the unlocking process, the rope is fused from inside to outside, the fused surface of the rope can be more tidy, and the service life of the rope is prolonged. Unlocking lagging caused by expansion of the fusing face of the rope is effectively avoided, the unlocking process is smoother, and the heat knife unlocking mechanism has higher safety.

    本公开涉及压紧解锁机构领域,具体涉及热刀解锁机构、安装方法及卫星。热刀解锁机构包括:第一装置,用于与第一部件固定连接;第二装置,用于与第二部件固定连接;绳索,缠绕于第一装置与第二装置外,锁紧第一装置与第二装置;热刀组件,与第一装置滑动连接,抵接于绳索内侧,用于加热熔断绳索。本公开通过绳索锁紧实现对第一部件及第二部件的锁紧。能够使热刀组件在第一装置上滑动,使热刀组件能够由绳索的内侧向外移动,加热并熔断绳索实现解锁,在解锁的过程中冲击力较小,且由内向外熔断绳索,能够使绳索的熔断面更加整齐,有效避免出现绳索熔断面膨胀的情况导致的解锁卡顿,使解锁过程更加流畅,使热刀解锁机构有更高的安全性。
