3. The connection mechanism of claim 1, further comprising:
the first elastic piece is arranged in the first accommodating cavity (11), and the ejector rod (31) is coated by the first elastic piece.
4. The connection mechanism of claim 1, further comprising:
the second elastic piece is arranged in the first accommodating cavity (11), one end of the second elastic piece is connected with the supporting seat, and the other end of the second elastic piece is connected with the driving assembly (33).
5. The connecting mechanism according to claim 1, wherein the clamping piece (2) is provided with a mounting hole,
the clamping piece (2) penetrates through the mounting hole through the rotating shaft to be connected with the inner wall of the second accommodating cavity (12).
6. The connection mechanism according to claim 1, wherein the drive assembly 33 comprises a drive post (332) and a force plate (333),
the driving column (332) is connected with the force application plate (333), and the force application plate (333) is connected with the inner wall of the first accommodating cavity (11).
7. A vehicle comprising the connecting mechanism according to any one of claims 1 to 6,
a vehicle body connecting piece, which comprises a bulge, wherein the bulge is arranged at the clamping interface,
the driving assembly (33) can drive the first supporting seat (32) to move upwards relative to the first accommodating cavity (11) so as to drive the ejector rod (31) to enter the second accommodating cavity (12) through the through hole, and the ejector rod (31) extrudes the clamping piece (2) when entering the second accommodating cavity (12), so that the clamping piece (2) at least partially stretches out of the clamping interface to hook the bulge so as to prevent the vehicle body connecting piece and the connecting structure from moving relatively;
the driving assembly (33) can also drive the first supporting seat (32) to move downwards relative to the first accommodating cavity (11) so as to drive the ejector rod (31) to penetrate through the through Kong Tuihui and the first accommodating cavity (11), and the ejector rod (31) releases the extrusion of the clamping piece (2) when retreating from the first accommodating cavity (11), so that the clamping piece (2) is accommodated in the second accommodating cavity (12) so as to allow the vehicle body connecting piece and the connecting structure to move relatively.
