Three-section pressure type automobile ventilation device

Abstract

The invention relates to a three-stage pressure type automobile ventilation device, which comprises an outer cylinder, a turbofan and an inner cylinder placed inside the outer cylinder; the turbofan can slide left and right on the outer cylinder and is placed on the right side of the inner cylinder; There is a tension spring, and the two ends of the tension spring are respectively connected with the outer cylinder and the turbofan; the inner cylinder is rotatably mounted on the outer cylinder and can slide left and right, and there are multiple fan blades on the inner cylinder; there are multiple windshields on the outer cylinder There is a slider on the outer cylinder, a straight rod on the slider, a spiral cam groove on the straight rod, a cam push rod on the air outlet baffle, a cam push rod placed in the cam groove, and a cam push rod on the outer cylinder. There is an air outlet; there is a push rod on the slider, and the right end of the push rod is connected to the turbofan through a spring; there is a fixed cylinder inside the outer cylinder, and the fixed cylinder and the outer cylinder are connected by multiple connecting plates. The left end of the drum is in contact with the drum, and the fixed drum has a pressure spring in contact with the left end of the drum; there are multiple radial rods on the drum, and there are multiple spiral cam grooves on the fixed drum, and the radial rods are placed in the cam grooves. There are longitudinal baffles on the radial rods.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle air conditioning equipment, 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 consumption ...
