Embodiment

[0053] figure 1 It shows the installation schematic diagram of the hinge structure used for the trunk lid of the automobile in this embodiment. The active force provided by the torsion spring 1 and the reaction force provided by the hinge structure 2 solve the problem that the opening speed of the lid 3 is too fast and the closing force is large. The problem of the case lid 3 is directly bounced to the highest when it is opened, and the purpose of increasing the active force applied to the case lid 3 is not needed when closing.

[0054] Such as figure 2 As shown, the hinge structure 1 of the present embodiment comprises a damping element 201, a hinge holder 202, a hinge arm 204, a connecting plate 203, a damping element 201, the hinge holder 202 is used to connect the trunk of a car, and the hinge arm 204 One end is hinged to the hinge holder 202, and the other end is used to connect the case cover 3 of the trunk of the car. One end of the connecting plate 203 is hinged to t...

Abstract

The invention discloses a hinge structure for an automobile trunk lid and an automobile. The hinge structure comprises a hinge fixing seat, a hinge arm, a connecting plate and a damping element, the hinge fixing seat is used for being connected with a trunk body of an automobile trunk, one end of the hinge arm is hinged to the hinge fixing seat, and the other end of the hinge arm is used for being connected with the trunk lid of the automobile trunk; and one end of the connecting plate is hinged to the hinge arm, the other end of the connecting plate is used for being connected with a torsion spring, a slideway is formed in the hinge fixing seat, one end of the damping element is hinged to the hinge arm, and the other end of the damping element is arranged in the slideway and can slide along the slideway along with movement of the hinge arm. In the opening or closing process of the trunk lid, after the other end of the damping element slides to one end of the slideway, the trunk lid continues a stroke of opening or closing under the action of the torsional spring, and the damping element is stressed to be compressed or stretched to achieve the speed reduction and buffering effects. The damping force generated when the trunk lid is opened to the high position is increased, so that the opening speed is reduced, and meanwhile the problem that the closing force is large is solved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and more specifically relates to a hinge structure for a trunk lid of an automobile and the automobile. Background technique [0002] The trunk of the sedan has a high frequency of use, and the traditional trunk lid uses a torsion spring as the power source for the trunk lid to open. The torsion spring is used as the power source for opening the trunk lid. When opening the trunk lid of the vehicle, it is usually designed to pop up to the middle position and then fully opened by hand. It is inconvenient to use; if the torsion spring force is increased, the luggage If the trunk lid directly pops up to the highest position, it will cause the problems of too fast opening speed of the trunk lid and large closing force of the trunk lid. [0003] Therefore, it is expected to develop a hinge structure and automobile for the trunk lid of a car, so as to achieve the goal of directly springing up to th...
