Embodiment Construction

[0011] Below in conjunction with accompanying drawing, the utility model is further described.

[0012] see figure 1 and figure 2 A kind of car front cover hinge shown, its rivet connecting male hinge 1 and female hinge 2 is a step rivet 4, and one section diameter of this step rivet is larger, and one section diameter is smaller; A self-lubricating bushing 3 is arranged on the female In the pin hole of the hinge 2, the stage with a larger diameter of the step rivet 4 cooperates with the self-lubricating bush 3, and the stage with a smaller diameter of the step rivet 4 cooperates with the pin hole of the male hinge 1.

[0013] The working surface of the self-lubricating bush has the following two functions. First, when the male hinge and the female hinge are in relative motion, the working surface of the self-lubricating bush is in contact with the male hinge, reducing the frictional resistance of the movement and preventing abnormal friction noise. . Second, when the step...

Abstract

The invention discloses an automobile front cover hinge, which comprises a male hinge and a female hinge connected with the male hinge, and is characterized in that: a rivet which connects the male hinge with the female hinge is a stepped rivet; the stepped rivet is provided with a larger-diameter section and a smaller-diameter section; a self-lubricating bush is arranged in a pin hole of the female hinge; the larger-diameter stepped section of the stepped rivet is matched with the self-lubricating bush; and the smaller-diameter stepped section of the stepped rivet is matched with a pin hole of the male hinge. The self-lubricating bush is arranged and connected with the female hinge in a matched mode, and the female hinge and the male hinge are riveted together by the stepped rivet, so that the female hinge and the male hinge flexibly and smoothly move and do not generate friction and abnormal noise, and the problems of inflexible and unsmooth movement and abnormal noise of the conventional hinge connecting device are solved.

Description

technical field [0001] The invention relates to the connection of automobile parts, in particular to an automobile front cover hinge. Background technique [0002] The hinge of the front hood of the automobile is the core component to realize the opening and closing of the front hood. The opening and closing performance of the front hood hinge directly affects the opening and closing performance of the front hood. At present, the traditional hinge riveting connection method can be found in figure 1 . The male hinge and the female hinge are directly riveted with flat head rivets. After riveting, the outer convex table of the female hinge of the front cover hinge is in surface contact with the male hinge. Since the surface of the male and female hinges is generally not processed, it is the same as the surface of the raw material, and the surface is not smooth. , In addition, when riveting, the flat-head rivet is deformed by hand to form a flange surface, which is directly in ...
