[0001] The present invention relates to the field of biosafety protection technology and equipment technology, and in particular to a vehicle-mounted expandable mobile biosafety laboratory. Background Art

[0002] A biosafety laboratory, also known as a biological laboratory, is a place for conducting experiments related to biological sciences. As the requirements for quality control become increasingly stringent, the demand for a constant temperature and humidity environment is increasing, and the scope of application is becoming wider and wider. With the gradual development of the times, in order to achieve emergency operations, vehicle-mounted mobile biological laboratories are gradually developed, which are convenient for field testing and use, thereby improving the timeliness of use.
