Expansion and retraction device, bulletproof panel device, control methods and unmanned vehicle

Abstract

The invention relates to an expansion and retraction device, a bulletproof panel device, control methods and an unmanned vehicle. The expansion and retraction device comprises a telescopic supportingrod mechanism and a sliding mechanism, wherein the sliding mechanism comprises a fixed part at the bottom and a movable part at the top; the movable part moves back and forth relative to the fixed part; the upper end of the movable part is connected to the lower end of a to-be-expanded-and-retracted piece; the telescopic supporting rod mechanism is arranged beside the sliding mechanism; the telescopic supporting rod mechanism comprises telescopic rod pieces; and the rod pieces are connected to the upper end of the to-be-expanded-and-retracted piece. According to the expansion and retraction device, the bulletproof panel device, the control methods and the unmanned vehicle, bulletproof panels can be flexibly placed and quickly retracted and expanded so as to easily achieve automatic controlon the unmanned vehicle and enhance flexibility and protection capability.

Description

technical field [0001] The invention relates to the technical field of military and police bulletproof equipment manufacturing, in particular to a retractable device, a bulletproof panel device and an unmanned vehicle equipped with the device. Background technique [0002] Urban combat is increasingly becoming an important combat style for the army and special police in the future. Due to the lack of armored vehicle protection, foot combatants are extremely vulnerable to enemy light weapons, explosive devices and roadside bombs and cause serious casualties. Therefore, combat individual / single police Wear helmets, bulletproof vests and other protective equipment. However, limited by the load capacity of the human body, on the one hand, bulky personal protective equipment will seriously affect the mobility of individual soldiers. On the other hand, it can only provide certain ballistic protection for limited parts such as the head and torso. There are still a large number of p...

AI Technical Summary

Problems solved by technology

However, limited by the load capacity of the human body, on the one hand, bulky personal protective equipment will seriously affect the mobility of individual soldiers. On the other hand, it can only provide certain ballistic protection for limited parts such as the head and torso. There are still a large number of parts directly exposed to bullets, Explosive Fragmentation and Shockwave Threats

Although traditional bulletproof shields can provide protection for individual soldiers / police officers, due to inherent shortcomings such as heavy weight and difficulty in carrying, it is difficult to be widely used in rapidly changing tactical environments
