Air exchange structure capable of opening and closing air outlet automatically

Abstract

The invention discloses an air exchange structure capable of opening and closing an air outlet automatically. The air exchange structure is composed of a top cover (1), a water blocking ring (2), a middle ring assembly (3), a rotating cover assembly (4), a fan assembly (5) and an air outlet opening and closing assembly (6). The water blocking ring (2) and the middle ring assembly (3) are arranged between the top cover (1) and the rotating cover assembly (4). The top cover (1) and the rotating cover assembly (4) are closely combined through sealing glue and a screw. The fan assembly (5) is fixed in the middle ring assembly (3). The air exchange structure is characterized in that the air outlet opening and closing assembly (6) is fixed to the top cover (1) and located on the lower side of the fan assembly (5) and corresponds to the outer edge of a blade on the fan assembly (5). According to the air exchange structure, the position of the air outlet is greatly heightened, the area of the air outlet is great, and use under various working conditions can be met. When a vehicle stops running, the air outlet is automatically closed through electronic control, and key parts in the vehicle can be well protected.

Description

technical field [0001] The invention relates to the technical field of accessories for automobile sunroofs, in particular to a ventilation structure capable of opening and closing an air outlet by itself. Background technique [0002] The safety windshield is one of the important parts of the car. All kinds of passenger cars in my country generally have a safety windshield on the top of the vehicle, which can be used as an emergency exit in an emergency and can increase the convection between the air inside the car and the outside air. But the electric strong wind ventilating fan in the existing safety windshield for vehicles generally has the following problems in use: 1. the position of the air outlet is low, the area is small, the loss of air volume per unit time is large, and the total ventilation volume is small; Make the temperature inside the car rise, generate a high temperature alarm, seriously affect the normal driving of the vehicle. 2. When the vehicle is drivin...

AI Technical Summary

Problems solved by technology

But the electric strong wind ventilating fan in the existing safety windshield for vehicles generally has the following problems in use: 1. the position of the air outlet is low, the area is small, the loss of air volume per unit time is large, and the total ventilation volume is small; Make the temperature inside the car rise, generate a high temperature alarm, and seriously affect the normal driving of the vehicle

2. When the vehicle is driving in rainy days, it is easy to leak rain and wind, which will affect the work of the electrical components in the car

3. When the vehicle stops running, snowflakes, leaves and other debris can easily enter the vehicle through the air vent, causing damage to the core components of the vehicle
