What is the role of the car ventilation cover plate?
The function of the ventilation cover plate is to provide the air intake required by the air conditioner, prevent the external water of the car from entering the air conditioning intake system, and prevent the entry of external debris of the vehicle. In the daily process of using the car, such as parking for a long time or stopping under the tree, the vent on the ventilation cover plate is easy to be blocked by other debris such as leaves, thus affecting the normal operation of the Longtuner system.
As an important part of the vehicle, the ventilation cover plate plays an indispensable role in integrating the functions of the exhaust intake wiper nozzle assembly. In the previous model, the sink sheet metal is installed under the ventilation cover plate, and the rain can flow directly into the sink through the wiper mounting hole or drainage hole, and then discharge out of the car along the sink, effectively preventing the water from flowing into the body and the body sheet metal structure, which can provide a comfortable internal riding space, and prevent the body sheet metal from being corroded by rain.
In order to solve the above technical problems, the utility model provides a drainage structure of a ventilation cover plate, which comprises a water retaining wall of a ventilation cover plate body, a diversion channel and an air intake surface; The water retaining wall, flow guide trough and air inlet surface are arranged on the ventilation cover plate body, the air inlet surface is connected with the flow guide trough, and the water retaining wall is located between the air inlet surface and the flow guide trough. The two ends of the ventilation cover plate body are provided with connecting plates, and the connecting plates are inclined to one side. The connecting plate avoids interference with the head brace. The diversion channel and the air intake surface are connected on both sides near the body of the ventilation cover plate to form a water outlet.
The drainage structure of the ventilation cover plate also includes a head cover split drainage box and a water outlet connected to a splice of the head cover. The hood seam is the upward seam. The diversion groove is a curved groove. The diversion groove has a Z drop from the middle to both ends, which can ensure the smooth discharge of water and will not cause water accumulation on the ventilation cover body. Because there is no runner sheet metal in the layout requirements, it can not meet the requirements of its drainage performance, and can only drain through the two sides of the ventilation cover plate to improve the market of the new car.
The inlet surface has a step difference from the middle to both sides. The step difference prevents a large amount of water from flowing into the inlet. The inlet surface has a convex part. The convex part has multiple air intakes. The water flowing to the air intake side can be discharged along both sides, reducing the amount of water entering the air intake and avoiding air conditioning failures caused by water intake. The utility model also provides a vehicle which comprises a ventilation cover plate drainage structure mentioned in any of the above. The drainage structure of the ventilation cover plate also includes a drainage box; The drainage box is connected to the water outlet. There are two drainage boxes, two drainage boxes can make the water flow to the front wheel cover side to strengthen the outside of the beam to avoid backflow.
The failure of the vehicle ventilation cover plate may be caused by many reasons, including the failure of the ventilation cover plate, the failure of the air conditioner intake, the failure of the front windshield rubber strip, etc. In view of these faults, corresponding maintenance measures can be taken to solve them.
Ventilation cover plate fault : If the ventilation cover plate is faulty, it may cause loud wind noise.
air conditioning inlet failure : Air conditioning inlet failure is also a possible cause of ventilation cover plate failure. If the air conditioner valve is not switched properly, it may be necessary to disassemble the meter and the warm bellows for repair. The valve switch of the air conditioner is a key component to control the air flow. If the valve switch is faulty, the air conditioner may not produce air or the air volume is insufficient .
Front windshield rubber strip failure : A front windshield rubber strip failure can also cause problems related to ventilation covers.
bulge problem of ventilation cover plate : Bulge problem of ventilation cover plate. You can measure the distance between the middle hole edge of the flow sink and the front windshield edge to determine whether the gap problem causes the deformation of the ventilation cover plate. If the distance exceeds the standard value, it can be solved by reassembling the flow tank and strengthening the support, adjusting the installation of the ventilation cover plate .
Vent cover and front stop deadhesive opening : If the vent cover and front windshield have deadhesive opening problems, first check whether the vehicle is still within the warranty period.
To sum up, the solution to the failure of the vehicle ventilation cover includes checking and repairing the ventilation cover, air conditioning intake, and front windshield rubber strip and other components to ensure that they work properly to avoid failure.
