Description

Luggage compartment door hinge buffer structure

Technical Field

The utility model belongs to the technical field of the car, concretely relates to luggage compartment door hinge buffer structure.

Background

The trunk door of the automobile must have the function of stopping at the highest position after being opened so as to be convenient for a user to take and place articles. The function is generally realized by an elastic part connected between a trunk door hinge (generally, a pipe body with a rectangular cross section) and a vehicle body, however, the elastic part releases force quickly, and the trunk door shakes a large amount after being opened to the top, which affects the operation comfort of a user.

The patent document (publication number: CN205499076U) in China discloses a limit buffer structure and a hinge structure of an automobile trunk lid, wherein the buffer structure comprises a rubber block and a mounting bracket, the mounting bracket is provided with a rubber block mounting groove for clamping the rubber block, the rubber block is provided with a hinge mounting groove, and the opening end of the hinge mounting groove is provided with a hook part for supporting a hinge. The buffer block among this technical scheme welds on the automobile body through the installing support, under luggage-boot lid (promptly luggage compartment door) open mode, the hinge inlays and locates buffer structure's hinge mounting groove in, thereby the rubber block takes place elastic deformation and inlays to establish to the hinge and form certain cushioning effect, and hook portion forms limiting displacement to the hinge simultaneously, can make the luggage-boot lid stop at highest position. However, when the hinge moves rapidly, the hinge entering the rubber block mounting groove through the buffer of the hook part still has a faster speed, the deformation of the groove bottom of the rubber block mounting groove caused by the extrusion of the hinge is smaller, the hinge rebounds to the hook part, the hook part is stressed again, the energy of the hinge cannot be fully absorbed, and the problem that the hinge and the vehicle door shake occurs.

Disclosure of Invention

The utility model discloses to the above-mentioned problem that prior art exists, provide a luggage compartment door hinge buffer structure, the utility model aims to solve the technical problem that: how to prevent the luggage compartment door from shaking when opened.
