Armored car window fastening structure with explosion preventing and buffering functions and fastening method

Abstract

An armored vehicle window fastening structure having a blast-proof cushioning function and a fastening method for the structure, comprising a mounting frame body (1) and a transparent window (2) fixedly mounted onto an armored vehicle main body (5) via the mounting frame body (1). The mounting frame body (1) has formed a first mounting groove (10). A side of the transparent window (2) is inserted into the first mounting groove (10). A circular frame body (3) is joined at the side of the transparent window (2). The frame body (3) and the first mounting groove (10) have formed therebetween mounting structures that match with each other. The frame body (3) comprises a pressing component (31) and a fastening component (32). The pressing component (31) and the transparent window (2) work in tandem to press onto the fastening component (32) to generate a prestress, thereby fastening the transparent window (2). The fastening structure is of high strength and widely applicable.

Description

technical field [0001] The invention relates to various armored vehicles in the field of national defense construction, in particular to a fastening structure and a fastening method for a transparent window of an armored vehicle with an explosion-proof buffer function. Background technique [0002] Armored vehicles are generally a general term for armored military or police vehicles. In order to adapt to the characteristics of modern warfare, as well as the needs of combating terrorist activities and maintaining social order, the development of various military, police and civilian armored vehicles has made great progress in recent years, such as armored personnel carriers, armored anti-riot vehicles, Armored Cash Carrier, etc. The characteristic of an armored vehicle is that it has a high degree of off-road mobility, and has a certain degree of protection and firepower. Therefore, the windshield and side windows of the vehicle must also have corresponding protection capabi...

AI Technical Summary

Problems solved by technology

In this installation method, the window is not integrated with the armored vehicle, and the window is basically in a free state. Once it is subjected to the impact load of an explosion outside the vehicle or a bullet, although the window will not be completely broken into small particles like tempered glass, it will be partially broken into small particles. It is broken and deformed in the impact direction under the action of the impact and remains intact under the action of the internal colloid, but the overall bending deformation of the form is bound to occur, and at this time the outer dimension of the form will be smaller than the inner diameter of the frame

Therefore, the window may escape from the frame as a whole and fly into the car, causing casualties to the people in the car, and cannot play its due protective effect.

Although the RET holding value of the form (glass weight after explosion impact / glass weight before explosion impact) is larger than ordinary glass, it is always less than 1 and cannot be guaranteed to be equal to 1

[0004] In order to reduce the impact of the above-mentioned defects on the safety of the occupants in the car, the area of ​​the window is usually reduced during design, or the width of the ribs on both sides of the window is increased. As a result, the vision of the driver and other people in the car is simultaneously reduced. Small, which brings inconvenience to the driving of the vehicle and the observation of the people in the vehicle

[0005] In addition, because the window and the vehicle are not integrated, there is a gap between the two. When the vehicle is exploded or violently shaken, a rigid collision will inevitably occur between the window, which is a brittle material, and the rigid frame, causing the window It first appears stress concentration or even cracks and loses its protective effect

[0006] The above-mentioned installation method and structure of the transparent window of the armored vehicle still have certain defects, and there are no targeted solutions and technical solutions. Therefore, related safety hazards always exist, and it has become a major problem that has always plagued relevant technical personnel.

[0007] However, with the progress of the times, the application of armored vehicles in national defense and other fields has become more and more common, but the core technology that can effectively improve the security and convenience of the fastening support structure of the transparent window of armored vehicles has not yet been resolved.

For such important issues that affect national defense construction and the safety of people's lives and properties, there is currently no reasonable solution, and the present invention fills the gap in this field
