Description

Technical Field

[0001] This utility model relates to the field of special vehicle armor protection and electromagnetic compatibility technology, specifically a protective plate for the air conditioning vents in the driver's cab that meets the requirements of electromagnetic shielding and bulletproofing. Background Technology

[0002] In the existing technological field, the air conditioning openings in the driver's cab have two major drawbacks: the lack of structural consideration for bulletproof functionality and the absence of effective electromagnetic sealing measures. These shortcomings prevent the simultaneous fulfillment of the combined requirements of bulletproofing, high electromagnetic shielding, and sealing. To meet the stealth and electromagnetic compatibility requirements of modern electronic warfare, the driver's cab must also possess excellent electromagnetic shielding performance, forming a complete "Faraday cage" to prevent external electromagnetic signal intrusion or internal signal leakage.

[0003] Therefore, protective plates are often installed at the air conditioning openings. However, most of the previous protective plates had louvers for ventilation, which made it difficult to achieve the purpose of shielding signals and avoid external electromagnetic interference. This, in turn, affected the transmission of signals inside the driver's cab and the control of various circuits, resulting in poor shielding effect.

[0004] Now, a new type of protective plate for the air conditioning vents in the driver's cab that meets the requirements of electromagnetic shielding and bulletproofing is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a protective plate for the air conditioning vents in the driver's cab that meets the requirements of electromagnetic shielding and bulletproofing, so as to solve the problem of poor protection effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective plate for the air conditioning vents in a driver's cab that meets the requirements for electromagnetic shielding and bulletproofing, comprising a top plate, side plates respectively provided at the front and rear ends of the bottom of the top plate, a rear plate provided on the left side of the bottom of the top plate, and a front plate provided on the right side of the bottom of the top plate, wherein a slot is provided inside the front plate, and a louver 19 is movably installed between the front and rear ends inside the slot, two sets of clip frames are fixed on the right side of the inner wall of the front and rear side plates, and a slot is provided between the clip frames on both sides, and a sleeve plate is longitudinally inserted and fixed between the front and rear slots, and a metal wire shielding mesh is fixed in the sleeve plate.
