An unmanned aerial vehicle air-drop grenade assembly comprises a grenade body and an outer shell, a parachute bag is arranged on the upper side of the outer shell, and a supporting base, a vertical baffle, an elastic plug and a triggering mechanism composed of a U-shaped bracket and a swing arm are arranged in the outer shell. An inverted-truncated-cone-shaped guide base is arranged at the bottom of the outer shell and connected with the outer shell through bolts and nuts, and two connecting rods are arranged on the guide base and hinged to the U-shaped bracket. During use, the parachute is thrown after nuts are removed, and the parachute is unfolded and stably falls. When touching the ground, the guide base firstly touches the ground, the outer shell continues to move downwards, the connecting rod pushes the swing arm to rotate upwards, the safety pin and the elastic plug are sequentially pulled out, and instant protection releasing and detonation are achieved. The assembly can keep the grenade in the air non-insurance-releasing state, improves the throwing safety, is stable and reliable in structure, and is suitable for unmanned aerial vehicle air-drop combat.

A disclosed field expedient munition mechanism includes an outer adapter sleeve housing and an inner sliding nose member. The outer adapter sleeve housing includes a proximal end and a distal end. The proximal end includes a mounting interface configured to mount the outer adapter sleeve housing to the aerosol container around the nozzle. The inner sliding nose member is configured to slide within the distal end of the outer adapter sleeve housing. The inner sliding nose member is configured to displace the nozzle of the aerosol container when pushed into the distal end of the outer adapter sleeve housing. A dispersion path is included from the nozzle to out of the field expedient munition mechanism. Wherein, when the inner sliding nose member is pushed into the distal end of the outer adapter sleeve housing, the inner sliding nose member displaces the nozzle of the aerosol container.

The application provides an intelligent hand grenade and a security method thereof. The security method comprises the following steps: setting a theftproof device of the intelligent hand grenade to start, collecting motion information of the intelligent hand grenade, calculating the motion information of the intelligent hand grenade, judging whether the motion state of the intelligent hand grenade is in a stolen state, and locking a fuse device of the intelligent hand grenade when the motion state of the intelligent hand grenade is in the stolen state. The security method can improve the transportation safety of the hand grenade and prevent the hand grenade from being lost and used for dangerous purposes.
