[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1-2A coil spring powered trunk lid 5 comprises: a gooseneck hinge 4, the first end of which is fixedly connected to the gooseneck hinge 4; a hinge mounting base 3, which is fixedly mounted on the vehicle body, and the second end of which is hinged to the hinge mounting base 3; and a damping mechanism, the second end of which is also connected to the hinge mounting base 3 via the damping mechanism. On the basis of a general gooseneck hinge 4, a coil spring 2 is used as the power source of the hinge. The coil spring 2 has the characteristics of simple manufacture, light weight and low cost, and can be installed on the hinge and supplied as an assembly. The assembly is installed on the vehicle, which effectively saves the man-hours of the OEM, improves the production rhythm, and can effectively avoid the problems of abnormal noise, oil leakage and air leakage.
