钢球11，位于设置在上盖01的圆柱体壁上的圆孔中；The steel ball 11 is located in the round hole arranged on the cylinder wall of the upper cover 01;
其中，当记忆合金丝06没有通电时，锁紧套02在扭簧(03)与记忆合金丝06共同作用下保持在锁紧位置，钢球11在锁紧套02的作用下，压入设置在拉钉12表面的凹坑中，从而将拉钉12在轴向和圆周方向锁死；Wherein, when the memory alloy wire 06 is not energized, the locking sleeve 02 is kept in the locked position under the joint action of the torsion spring (03) and the memory alloy wire 06, and the steel ball 11 is pressed into the setting under the action of the locking sleeve 02 In the pit on the surface of the pull stud 12, the pull stud 12 is locked axially and circumferentially;
且其中，当给记忆合金丝06通电时，记忆合金丝06达到相变温度后收缩，其收缩力克服扭簧03阻力和摩擦力使锁紧套02围绕上盖01的圆柱体旋转，当设置在锁紧套02上的轴向槽转到钢球11处时，钢球11向外落入锁紧套02的轴向槽内，解除对拉钉12的锁紧，拉钉在压簧09和外力作用下向上脱出，实现解锁。And wherein, when the memory alloy wire 06 is energized, the memory alloy wire 06 shrinks after reaching the phase transition temperature, and its contraction force overcomes the resistance and friction of the torsion spring 03 to make the locking sleeve 02 rotate around the cylinder of the upper cover 01, when set When the axial groove on the locking sleeve 02 turns to the steel ball 11, the steel ball 11 falls into the axial groove of the locking sleeve 02 outwards, releasing the locking of the pull rivet 12, and the pull rivet is locked on the compression spring 09 And under the action of external force, it will come out upwards to realize unlocking.
在一些实施例中，所述解锁机构100还包括紧定螺钉08，其通过壳体05上设置的窗口安装在上盖01的圆柱体壁上设置的螺孔中，并伸入拉钉12上设置的滑槽中，从而确保拉钉12与上盖01之间的导向。In some embodiments, the unlocking mechanism 100 also includes a set screw 08, which is installed in a screw hole provided on the cylindrical wall of the upper cover 01 through a window provided on the housing 05, and extends into the pull stud 12 In the provided chute, the guidance between the pull stud 12 and the upper cover 01 is ensured.
在一些实施例中，所述解锁机构100还包括固定螺钉07，用于通过壳体05的底部设置的孔将解锁机构100安装在卫星上，例如安装在卫星的箱体上。In some embodiments, the unlocking mechanism 100 further includes a fixing screw 07 for installing the unlocking mechanism 100 on a satellite, for example, on a satellite box, through a hole provided at the bottom of the casing 05 .
在一些实施例中，所述解锁机构100还包括螺钉10，用于将导丝套04与上盖01固定在一起。In some embodiments, the unlocking mechanism 100 further includes a screw 10 for fixing the guide wire sleeve 04 and the upper cover 01 together.

所述记忆合金丝06可以通过一开关电路(未示出)与电源连接，从而可以控制对记忆合金丝06的通断电。The memory alloy wire 06 can be connected to a power source through a switch circuit (not shown), so that the power on and off of the memory alloy wire 06 can be controlled.
所述导丝套04的表面设置有螺纹，用于确保记忆合金丝06的螺旋缠绕，这样，当记忆合金丝06通电收缩时，可以在导丝套04内滑动。由于记忆合金丝一端固定，另一端就会移动，从而对锁紧套02产生切向拉力，形成扭矩，使得锁紧套02围绕上盖01的圆柱体旋转，因而使钢球11向外滑脱，从而解锁拉钉12。Threads are provided on the surface of the guide wire sleeve 04 to ensure the helical winding of the memory alloy wire 06, so that when the memory alloy wire 06 is energized and contracted, it can slide in the guide wire sleeve 04. Since one end of the memory alloy wire is fixed, the other end will move, thereby generating a tangential pulling force on the locking sleeve 02 and forming a torque, so that the locking sleeve 02 rotates around the cylinder of the upper cover 01, thus causing the steel ball 11 to slip outward, The pull stud 12 is thus unlocked.
所述上盖01的盖板可通过螺钉固定在壳体05上。The cover plate of the upper cover 01 can be fixed on the housing 05 by screws.
