Movable environment test chamber for automobile environment wind tunnel laboratory

Abstract

Disclosed is a movable environment test chamber for an automobile environment wind tunnel laboratory. The movable environment test chamber for the automobile environment wind tunnel laboratory comprises an environment test cabin, a temperature and humidity control system, a fresh air system and a tail gas discharge system, wherein a chassis of the environment test cabin is settled into a pit, a floor of the environment test cabin and a floor of the wind tunnel laboratory keep at the same horizontal height, the environment test cabin is supported on two rails arranged in the pit in slide mode, a drive mechanism A is arranged on the chassis of the environment test cabin, a folding seal connection channel and a drive mechanism B are arranged on the position of an exit door of the environment test cabin, one end of the seal connection channel is connected with the periphery of the exit door of the environment test cabin, the other end of the seal connection channel is provided with a free connector which can be connected with the periphery of an entrance door and the exit door of cars of the wind tunnel laboratory, the temperature and humidity control system, the fresh air system and the tail gas discharge system are arranged on a building structure on the exterior of the environment test cabin, and connected with an air inlet, an air outlet and a tail gas discharge pipeline, which are arranged on the environment test cabin, through corresponding pipelines. According to the movable environment test chamber for the automobile environment wind tunnel laboratory, the environment test cabin is directly connected with the wind tunnel laboratory, and a drying chamber is not needed.

Description

technical field [0001] The invention relates to the technical field of automobile environment simulation tests, in particular to a movable environment test chamber used in an automobile environment wind tunnel test chamber. Background technique [0002] The automotive environmental test chamber is an important part of the environmental wind tunnel laboratory. When conducting low-temperature tests, in order to shorten the test preparation time, first put the entire test vehicle into the automotive environmental test chamber for pre-cooling. test. [0003] Using the automotive environmental test chamber can reduce the energy consumption of the environmental wind tunnel test room. At present, the design of the automotive environmental test chamber can be divided into fixed type and air cushion mobile type from the structure. Figure 9 Presented in is the fixed vehicle environmental test chamber. Figure 10 Presented in is the air cushion mobile vehicle environmental test cha...

AI Technical Summary

Problems solved by technology

Since the overall space of the automotive environmental test chamber is relatively compact, and in order not to change the temperature of the prepared test vehicle, the test vehicle cannot be started, so it is necessary to push the test vehicle into and out of the automotive environmental test chamber by manpower, causing the test vehicle to enter and exit the automotive environmental test. very inconvenient

In addition, due to the air cushion type movement, the mobile positioning accuracy of the automotive environmental test chamber is poor, which increases the difficulty of docking with the drying room; the temperature and humidity control system, fresh air system and exhaust emission system of the automotive environmental test chamber are integrated in the automotive environmental test chamber The top of the vehicle environment test chamber is heavier, and it is more laborious to move.

In addition, if the existing fixed automotive environmental test chamber or air cushion mobile automotive environmental test chamber is used, a drying room is set between the environmental test chamber and the automobile wind tunnel test chamber, which leads to the large occupation of the entire environmental wind tunnel test chamber. Building space, and the operating cost of the environmental wind tunnel is also high
