Problems solved by technology

[0002] As the first choice of transportation for people to travel, cars have become more and more popular, and people have higher and higher requirements for the comfort and economy of cars. The quality of the sealing will affect the noise insulation effect of the car cabin, the economy of the car HVAC system, the comfort of the occupants and the infiltration of external air during the driving process of the car. The existing testing equipment can only complete three kinds of measurements. For some tests in the experiment, there is no equipment that can simultaneously complete the three tests. In these three tests, the maximum and minimum values ​​of the measured air volume data are very different. In the prior art, flow ducts or Sensors such as anemometers measure air flow, and the flow measurement range cannot be finely adjusted, resulting in excessive errors, unable to provide accurate data, and the degree of automation is low, and the mobility is poor

Abstract

Disclosed is a sealing device for an automobile cabin and HVAC air-vent air quantity and air door. The sealing device relates to the fields of automobile detection, automobile HVAC air-vent detection and air-flow control. The sealing device includes a test fixture (1), a first connecting air duct (2), a multi-nozzle air-chamber air channel (3), a second connecting air duct (4) and a frequency-conversion fan (5). The test fixture (1) is connected with the multi-nozzle air-chamber air channel (3) through the first connecting air duct (2); and the multi-nozzle air-chamber air channel (3) is connected with the frequency-conversion fan (5) through the second connecting air duct (4). A testing device with a function of three-test measurement is proposed so that cost is reduced. Parts capable of adjusting flow range are used so that measurement precision is improved and data proof for automobile quality improvement is provided and thus automation degree and mobility of the device is improved and convenience is provided to the device for switch among different space environments.

Description

Technical field: [0001] The invention relates to the fields of automobile detection, automobile HVAC air outlet detection and air fluid control, in particular to an automobile cockpit, an HVAC air outlet air volume and a sealing device for an air door.
