Three-section pressure type automobile ventilating device

Abstract

The invention relates to a three-section pressure type automobile ventilating device. The three-section pressure type automobile ventilating device comprises an outer barrel, a turbofan capable of sliding left and right on the inner side of the outer barrel and an inner barrel placed on the left side of the turbofan, a tension spring is arranged on the outer barrel, and two ends of the tension spring are separately connected to the outer barrel and the turbofan; the inner barrel is rotatably mounted on the outer barrel and can slide left and right on the inner side of the outer barrel, a plurality of fan blades are arranged on the inner barrel, an arc-shaped baffle plate capable of sliding left and right is arranged on the outer barrel, a plurality of first air outlets are formed in the arc-shaped baffle plate, and a plurality of second air outlets are formed in the outer barrel; a straight rod capable of sliding left and right is arranged on the outer barrel, the left end of the straight rod is connected to the arc-shaped baffle plate, and the right end of the straight rod is connected to the turbofan trough a spring; a fixed barrel placed on the left side of the inner barrel is arranged on the inner side of the outer barrel, the fixed barrel and the outer barrel are connected through a plurality of connecting plates, a rotary drum which can slide and rotate and is in contactwith the inner barrel is arranged on the fixed barrel, and a horizontal pressure spring in contact with the rotary drum is arranged on the fixed barrel; and a plurality of radial rods are arranged onthe rotary drum, a plurality of spiral cam grooves are formed in the fixed barrel, the radial rods are placed in the cam grooves, and longitudinal baffle plates are arranged on the radial rods.

Description

technical field [0001] The invention relates to the technical field of air-conditioning equipment for new energy vehicles, in particular to a three-stage pressure type vehicle ventilation device. Background technique [0002] During the use of the car, the lighting, alarm, air-conditioning and other systems inside the car need to rely on electricity to operate normally. Among them, the air-conditioning system consumes a large proportion of power. In order to reduce fuel consumption and extend the mileage, you can choose to turn off the air-conditioning, Internal lighting and other non-essential electrical equipment to achieve the purpose of energy saving; [0003] However, during high-speed driving, due to the fast flow of air outside the car, if the air conditioner is turned off and the windows are opened for ventilation and cooling, the wind noise will increase, and the resistance formed after the air flows through the window into the car will further increase fuel consump...
