At this time, the first protective plate and the second protective plate are unfolded, the first protective net frame is attached to the first protective plate, and the second protective net frame is attached to the second protective plate. The front glass of the cab can be protected. In combination with the existing protective top cover, the driver's safety is greatly improved, and the driver has a certain field of vision for driving (low speed driving). When away from the dangerous mining area, the second protective plate is inserted into the first protective plate, and the second protective net frame overlaps with the first protective net frame and swings upward, which will not affect the driver's field of vision and can travel at high speed.

[0013] 2. The impact-resistant structure of the mine car cab is characterized by the second protective plate being inserted into the first protective plate, and the second protective net frame being overlapped with the first protective net frame (with the gap reduced). When the driver is resting, it can play a certain role in reducing light.
