Abstract

FIELD: vehicles. SUBSTANCE: invention relates to mechanisms for raising and lowering a side window of an armoured vehicle door. A window regulator comprises a rhombic linkage mechanism having a lead screw with a nut mounted in the rhombic linkage mechanism along its diagonal. One end of the lead screw is connected to an electric drive. a bed for an armoured window is attached to an upper part of the rhombic linkage mechanism by means of a support bracket. Gas springs are installed on both sides of the rhombic linkage mechanism. a lower end of each gas spring is fixed on an armour plate of the side door of the vehicle. An upper end of each gas spring is attached to the bed for the armoured window. EFFECT: increasing reliability of the window regulator and enabling use of an armoured window of greater mass. 2 cl, 8 dwg

Description

The invention relates to transport equipment, namely to mechanisms for raising and lowering 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. Special mechanisms, which can be installed in the vehicle doors, are used to raise and lower the armored glass. A prior art vehicle window regulator is disclosed in patent CN 208344222 U for a utility model, information on which was published on January 8, 2019, in the People's Republic of China. This window regulator comprises a diamond-shaped linkage mechanism formed by two pairs of pivotally connected levers. The lower lever of each pair is pivotally connected to a mounting bracket via a lower axial rod, and the upper lever of each pair is pivotally connected to a support bracket via an upper axial rod. To operate the linkage mechanism, the window regulator design includes chain cables driven by an electric motor. The first chain cable passes through the upper and lower axial rods, and the second chain cable passes through side rods that pivotally connect the upper and lower levers of each pair. The output shaft of the electric motor is connected to a transmission shaft containing two electromagnetic clutches. The chain cables are connected to the window lift motor via pulleys mounted on the transmission shaft. Additionally, a gas spring is pivotally mounted between the upper and lower arms of adjacent pairs. The drawback of this technical solution is that, with a large window weight, there is a risk of failure of the gas spring integrated into the linkage due to excessive load, which can lead to window lift failure. Furthermore, a design with chain cables and electromagnetic clutches does not provide sufficient force to raise and lower laminated armored glass. This design also suffers from low reliability due to stretching and deformation of the chain components. Closer to the technical essence of the invention is the window lift for a vehicle shown in the patent RU 221066 U1 for a utility model, information about which was published on October 17, 2023, in the Russian Federation. This window regulator comprises a diamond-shaped lever mechanism with a lead screw and nut mounted diagonally within the lever mechanism. One end of the lead screw is connected to the electric drive. The armored glass bed is secured to the upper part of the lever mechanism using a support bracket. A disadvantage of this window regulator design is the high current load on the electric motor when using heavy armored glass, which can lead to failure of the window regulator motor. The technical problem, the solution of which is provided by the implementation of the invention, is the excessive load on the electric window lifter drive when using armored glass of large mass: high current load on the electric motor and high wear of the worm gear pair of the reducer. The technical result achieved by the invention consists in increasing the reliability of the operation of a window lift for the door of an armored vehicle, as well as in ensuring the possibility of using armored glass of greater mass. The solution to the specified technical problem and the achievement of a technical result are ensured by the fact that in a window lifter for a vehicle, containing a diamond-shaped lever mechanism, having a lead screw with a nut, installed in the diamond-shaped lever mechanism along its diagonal, one of the ends of the lead screw is connected to an electric drive, on the upper part of the diamond-shaped lever mechanism, with the help of a support bracket, a bed of armored glass is secured, on one or both sides of the diamond-shaped lever mechanism, at least one gas spring is installed, the lower end of each gas spring is secured to the armor plate of the side door of the vehicle, and the upper end of each gas spring is attached to the bed of armored glass. By installing at least one gas spring on one or both sides of the diamond-shaped lever mechanism, the lower end of which is secured to the armor plate of the side door of the vehicle, and the upper end of which is secured to the bed of the armored glass, the reliability of the operation of the window lift for the door of the armored vehicle is increased, and the possibility of using armored glass of greater mass is also ensured. The ends of each gas spring are attached to the armor plate and the armored glass bed using brackets, bolted or welded.
