A train collision self-turning safety table comprises a table top, guiding sliding blocks, supporting rib plates, a mechanism installation base, a torsional spring, table top locking and positioning keys and a buffer spring. The mechanism installation base is installed on a wall beside a train seat. The two supporting rib plates are installed on the mechanism installation base in parallel. The table top is installed on the two supporting rib plates. The guiding sliding blocks, the torsional spring and the buffer spring are installed below the table top and fix the table top. The seven table top locking and positioning keys are uniformly and fixedly installed on a panel of the mechanism installation base in an arc shape. The train collision self-turning safety table can buffer the collision between a passenger and the table top when a train accident happens, and therefore the response time for the passenger to conduct self-protection actively is prolonged. Through turning of the self-turning table, the contact form between the passenger and the table is changed from line contact to surface contact, and the contact area between the passenger and the table is greatly increased; and according to the Newton's laws, the pressure borne by the passenger can be effectively decreased, and the passive safety of the passenger is improved.
