Lifting mechanism of cab side window glass of bulletproof vehicle

Abstract

The invention discloses a high-lifting force lifting mechanism of cab side window glass of a bulletproof vehicle. The lifting mechanism comprises a micro motor, a pedestal, and a speed reducer of a pair of worm wheel and worm which are mutually meshed, wherein the micro motor is fixedly arranged on an outer side of the pedestal; the output shaft of the micro motor is inserted into a side hole of the pedestal; and the worm wheel and the worm are positioned in the inner cavity of the pedestal, and the worm is arranged on the output shaft of the micro motor. The lifting mechanism also comprises a screw rod, a nut, a screw rod sleeve and a joint, wherein the screw rod is fixedly connected with the worm wheel by a coupling band; the nut is screwed to sleeve the screw rod; the screw rod sleeve is sleeved on the peripheral wall of the nut in a tight fit way, and positioned at the upper end of the nut; and the joint is fixedly arranged at the upper end of the screw rod sleeve and connected with the window glass. The lifting mechanism has the advantages of small volume, light weight, simple structure and the like, and can completely meet the lifting requirement of the bulletproof glass.

Description

technical field [0001] The invention relates to a lifting mechanism for a movable window glass of a passenger car, in particular to a lifting mechanism for a side window glass of a driver's cab of a bulletproof vehicle. Background technique [0002] As a special vehicle for financial and security services, the bulletproof cash transport vehicle has very high safety protection requirements. When an ordinary car is converted into a bulletproof car, the side window glass of the driver's cab must be completely refitted, and the original car glass must be replaced with bulletproof glass. Because the original car glass is relatively light, and the weight of the bulletproof glass far exceeds the original car glass, if the glass lifting mechanism of the original car is still used, the overweight bulletproof glass will not be able to be lifted. And if the bulletproof glass is completely fixed on the window frame, it will definitely affect the driver's connection with the outside wor...

AI Technical Summary

Problems solved by technology

Because the original car glass is light, and the weight of the bullet-proof glass is far more than the original car glass, if you still use the glass lifting mechanism of the original car, you will not be able to lift the overweight bullet-proof glass

And if the bulletproof glass is completely fixed on the window frame, it will certainly affect the connection between the driver and the outside world.

Furthermore, due to the lack of indoor air circulation, the driver is prone to driving fatigue when driving.
