Abstract

FIELD: vehicles. SUBSTANCE: invention relates to mechanisms for raising the side window of an armoured vehicle door. A device for emergency closing of a side door window, located between a window regulator and a window bed, comprises a base and a cover forming a device housing. Gas springs are crosswise installed inside the housing, the ends of which are hingedly mounted on the base and the cover of the housing. On the base of the housing, catches are installed on axles, contacting with retainers mounted on the cover of the housing. The catches are connected to each other by a rod. One catch is spring-loaded, and the other is connected to a control cable. EFFECT: increasing the operational safety of an armoured vehicle. 3 cl, 6 dwg

Description

The invention relates to transport equipment, namely to mechanisms for lifting the side window of an armored vehicle door. Armored vehicles use heavy laminated glass. A single pane of glass can weigh between 30 and 80 kg. To quickly raise the heavy armored glass in an emergency (such as a power outage), special mechanisms are installed in the side doors of the vehicle. In the event of a power outage, mechanical side window closing systems must be provided to protect passengers and the driver from potential unlawful actions (e.g., firearms bullets, explosive projectiles entering the vehicle interior, etc.). Therefore, to activate the side window lifting mechanism, an effective control element is required, activated in the event of a power outage. A device for lifting a vehicle side door window is known from the prior art, as shown in patent RU 2216454 C2, information about which was published in the Russian Federation on November 20, 2003. This device comprises two plates made of a shape memory material, one plate with a bending memory, the other with a straightening memory. One plate is attached to a bar that holds the base of the window, and the other plate is attached to the lower part of the vehicle side door body. Two pairs of links with articulated joints are attached to the ends of the plates. By alternately heating the plates, the device allows for repeated raising and lowering of the window. A drawback of this technical solution is that if the vehicle's on-board power supply is lost, the side door window lifting device will be inoperative. Furthermore, the design of the known device is not suitable for lifting heavy armored glass. A window regulator with an emergency opening mechanism for armored vehicles is also known from the prior art, as shown in patent RU 2736663 C1, information about which was published on November 19, 2020, in the Russian Federation. This window regulator consists of a lifting mechanism consisting of four levers, pivotally connected in pairs, with an electric drive based on a ball screw. The lifting mechanism is a double scissor mechanism, the upper levers of which are connected to the glass housing support via sliding bearings, and the lower levers are pivotally connected. One lower lever is attached to the sliding bearing, and the second to the base with a carriage sliding along guides together with the sliding bearing and a locking mechanism that maintains the position of the sliding bearing relative to the carriage using a catch. A gas strut is located on the axis of movement of the carriage and the sliding bearing of the lower lever inside the carriage, acting as an energy accumulator for operating the window regulator in an emergency. This is accomplished by a mechanical release mechanism, which consists of a cable drive with a handle on the door inside the vehicle. This drive is connected to a lever with a cam mechanism. When the handle is turned, the lever pushes a catch that disengages from the carriage, releasing the energy of the gas strut, which moves the sliding support of the lever mechanism with force, allowing the window to be lowered. A disadvantage of this design is that the window lift mechanism does not ensure the window is closed in an emergency, such as if the vehicle's electrical system is de-energized. Closer to the technical essence of the invention is a window regulator for an armored vehicle, shown in patent DE 202005013376 U1 for a utility model, information about which was published on January 26, 2006 in Germany. This window regulator comprises an electric drive mounted on the bed of armored glass, two guide rods secured to the side door panel, coil springs mounted on the guide rods, and a toothed rack located parallel to the guide rods and connected to the electric drive gearbox. When the side door window is opened, power is supplied to the electric drive, and the bed with the glass moves along the guide rods, compressing the coil springs. In the event of an emergency, for example, when the vehicle's on-board network is de-energized, the motor brake of the electric drive is disconnected, as a result of which the bed with the glass moves upward under the tension of the coil springs, closing the side door window of the vehicle. The disadvantage of this design is the high risk of incomplete window closure, as well as the slow closing speed due to the relatively low tension of the coil springs during the final stages of window closure, coupled with the heavy weight of the armored glass. This may increase the risk of bullets from firearms, explosive shells, toxic agents, and the like penetrating the vehicle's interior. The technical problem, the solution of which is ensured by the implementation of the invention, is to ensure the reliable closing of the side door window of an armored vehicle in the event of an emergency (for example, when the on-board network of the vehicle is de-energized). The technical result achieved by the invention consists in
