<p>A vehicle tailgate comprises a supporting frame (22) and a bearing platform. The bearing platform is connected to the supporting frame (22). The bearing platform comprises a primary bearing platform (211) and a secondary bearing platform (212) connected to the primary bearing platform (211) by a first torsion spring (28), and the free angle of the first torsion spring (28) is in the range of 90 degrees plus or minus 3 degrees. While the primary bearing platform (211) is open, the first torsion spring (28) is in energy-storage situation to supply part of power for closing the primary bearing platform (211), thus reducing labor intensity during manually closing. While the primary bearing platform (211) is closed, the first torsion spring (28) is still in energy-storage situation to supply part of power for opening the primary bearing platform (211), thus saving more effort and reducing labor intensity during manually opening. In the modification process, the vehicle tailgate with aforesaid structure employs the torsion spring, cost of which is far below that of installing an oil cylinder, thus lowering cost.</p> |
