Description

Technical Field

[0001] This utility model relates to the field of automotive injection molded parts, and in particular to an exhaust window assembly structure for an automotive luggage compartment. Background Technology

[0002] Luggage compartments are becoming increasingly indispensable in buses. These are hollow compartments used to store passenger luggage, increasing the bus's luggage capacity and making the passenger area more spacious and convenient for loading luggage. Currently, bus luggage compartment doors are large. When closing the last luggage compartment door while other doors are closed, a large amount of air is brought in, causing an increase in cabin pressure. This increased pressure exerts a reaction force on the door, resulting in it not closing properly or locking securely.

[0003] Publication (Announcement) No.: CN212950046U An exhaust window for a sealed luggage compartment in a passenger vehicle, characterized in that it includes a base and a cover plate rotatably disposed on the left side of the base. The beneficial effect of this utility model is that when the luggage compartment door is closed, the drive assembly is activated to move the cover plate, allowing the air inside the luggage compartment to circulate with the outside air through the exhaust port. This avoids an increase in the air pressure inside the compartment when the luggage compartment door is closed, and prevents the air pressure inside the compartment from generating a reaction force on the door, thereby preventing the door from not closing tightly or locking securely.

[0004] In the prior art, the pneumatic control structure includes a drive assembly 5 comprising a drive cylinder 7 fixedly mounted on the right side of the base 1, a fixed column 8 fixedly mounted on the base 1, and a hollow rotating shaft 9 rotatably sleeved on the fixed column 8. A mounting plate 10 is fixedly mounted on the hollow rotating shaft 9, and a push plate 11 is fixedly mounted above the mounting plate 10. The piston rod at the output end of the drive cylinder 7 is located directly behind the push plate 11. A push column 12 is fixedly mounted below the mounting plate 10, and a push plate is fixedly mounted on the right side of the cover plate 2. 13. The push plate 13 is connected to the push column 12 in contact. The push plate 13 is located to the left of the push column 12. When the cover needs to be opened, the drive cylinder is activated to ventilate, the piston rod of the drive cylinder moves, pushing the push plate to move. The push plate drives the mounting plate to move, the mounting plate drives the hollow rotating shaft to rotate on the fixed column, the hollow rotating shaft drives the push column to rotate, the rotating column drives the push plate to move, and the push plate drives the cover to move, opening the cover and facilitating the air circulation between the baggage compartment and the outside air through the exhaust port. However, the air pressure of the existing pneumatic structure is difficult to control, which can easily cause the opening angle of the window to be too large, further leading to damage to the components.
