Double-layer bulletproof air inlet grille, air inlet grille assembly and automobile

Abstract

The invention discloses a double-layer bulletproof air inlet grille which comprises an outer frame located at an air inlet of a front cover. The front end of the outer frame is fixedly connected witha fixed grille with a fixed blade inclination angle, the rear end of the outer frame is connected with a movable grille with an adjustable blade inclination angle, and linkage mechanisms capable of enabling blades of the movable grille to rotate together relative to the outer frame are fixedly arranged on the two sides of the blades of the movable grille. The invention further provides an air inlet grille assembly based on the double-layer bulletproof air inlet grille and an automobile. The air inlet grille assembly further comprises an operation device located in a cab, and a connecting rod mechanism for converting the reciprocating motion of an operating rod in a gear shifting channel into the reciprocating motion of a linkage rod is further connected between the operation device and thelinkage rod. The fixed grille mainly prevents bullets from directly penetrating through the grille blades, and the movable grille can intercept secondary bounce and splash debris by adjusting the blade inclination angle, and therefore the safety of the bulletproof automobile is ensured; and meanwhile, a driver can adjust the blade inclination angle of the movable grille according to actual conditions to realize different protection levels.

Description

technical field [0001] The invention relates to the technical field of automobile safety protection, in particular to a double-layer bulletproof air inlet grille, an air inlet grille assembly and an automobile. Background technique [0002] For protective vehicles, there is a problem that the bulletproof design of the air inlet and exhaust port is difficult, and it is difficult to balance the tightness of the bulletproof design and the smoothness of ventilation. At present, most of the air intakes of protective vehicles at home and abroad use fixed-slope grilles. This type of structure has overlapping blade projections within a certain angle range, which can reduce the probability of direct bullet leakage from the grille, but it cannot ensure the air intake performance of the grille. And anti-secondary ricochets. [0003] Chinese patent CN204136765U discloses a bulletproof air intake grille on the front cover. By setting a linkage mechanism on the back of the grille blades,...

AI Technical Summary

Problems solved by technology

Although this grille solves the contradiction between air intake performance and bulletproof performance to a certain extent, there is a risk that the parts behind the grille will be hit by blade splashes and the bulletproof will fail, and the angle of the blades cannot be adjusted when the vehicle is driving or encounters an emergency. Free adjustment, long preparation time for blade adjustment, difficult operation, unable to adapt to the needs of rapid modern combat, etc.
