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
The present invention relates to automobile component and connect, be specifically related to a kind of automobile front hood hinge.
Background technology
Automobile front hood hinge is a core component of realizing that front shroud opens and closes, and the switching performance of front shroud hinge directly influences the switching performance of front shroud, and the connected mode of conventional hinge riveted joint at present is referring to Fig. 1.Be directly with positive hinge and hinge with the flat head rivet riveted joint that presses, the evagination table top of riveted joint back front shroud hinge hinge contacts with positive hinge formation face, because the surface of negative and positive hinge does not generally process, the same, rough with the raw material surface, when riveting in addition, the distortion of flat head rivet hand-power forms flange face, the direct contact with the negative and positive hinge compresses, and flat head rivet is subjected to radially chap of axial force, overstocks with the negative and positive hinge pin aperture to contact.The front shroud hinge that this kind riveted syndeton opens and closes when moving, negative and positive hinge face and face mutual friction mutually, and flat head rivet axial plane and the friction of negative and positive hinge pin aperture face mutual extrusion being prone to the motion unlatching and having some setbacks, the friction abnormal sound; Show as the front shroud switching and have some setbacks in actual entrucking and use, user's operating physical force is overweight, friction of motion abnormal sound etc.Based on the present situation of this problem and market demand raising, the structure of front shroud hinge is badly in need of optimizing and is improved.
Summary of the invention
The purpose of this invention is to provide a kind of automobile front hood hinge, solve present automobile front hood hinge and open and close and have some setbacks, switching power is big and open and close the problem of friction abnormal sound.
A kind of automobile front hood hinge of the present invention comprises positive hinge and connected hinge, it is characterized in that: the rivet that connects positive hinge and hinge is a step rivet, and one section diameter of this step rivet is bigger, and one section diameter is less; One self-lubricating lining is located in the pin-and-hole of hinge, and the step section that the diameter of step rivet is bigger cooperates with the self-lubricating lining, and the pin-and-hole of the step Duan Yuyang hinge that the diameter of step rivet is less cooperates.
Described a kind of automobile front hood hinge, the pin-and-hole diameter of its described hinge and the external diameter basically identical of self-lubricating lining, and the flange and the hinge at self-lubricating lining two ends are close to.The self-lubricating lining uses installs the plug installation, and with flange plug flange, it is connected with hinge.
Described a kind of automobile front hood hinge, the diameter of the step section that the diameter of its described step rivet is bigger is less than or equal to self-lubricating lining internal diameter, to guarantee the smooth and easy flexible of motion; The diameter of the step section that the diameter of step rivet is less and the diameter basically identical of positive hinge pin aperture.The pin-and-hole of the step Duan Yuyang hinge that the diameter of step rivet is less adopts the basic shaft system interference fits.
Described a kind of automobile front hood hinge, the length of the step section that the diameter of its described step rivet is bigger is more than or equal to the thickness of self-lubricating lining two ends flange and the thickness sum of hinge, to guarantee between riveted joint positive hinge in back and the self-lubricating lining not mutual extrusion.
The present invention compares with prior art and has the following advantages: by increasing a self-lubricating lining, make it to be connected with hinge, with the step rivet yin, yang hinge is riveted together again, thereby makes the yin, yang hinge flexible and smooth and easy in motion process, do not produce the friction abnormal sound.It is dumb to have solved the motion of conventional hinge syndeton, has some setbacks and the abnormal sound phenomenon.
Description of drawings
Fig. 1 is an overall schematic of the present invention.
Fig. 2 is the sectional view that the present invention rivets the position.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Referring to a kind of automobile front hood hinge illustrated in figures 1 and 2, its rivet that connects positive hinge 1 and hinge 2 is a step rivet 4, and one section diameter of this step rivet is bigger, and one section diameter is less; One self-lubricating lining 3 is located in the pin-and-hole of hinge 2, and the step section that the diameter of step rivet 4 is bigger cooperates with self-lubricating lining 3, and the pin-and-hole of the step Duan Yuyang hinge 1 that the diameter of step rivet 4 is less cooperates.
The work plane of self-lubricating lining plays following two effects, and the first, during relative motion, the work plane of self-lubricating lining contacts with positive hinge, reduces the friction of motion resistance, prevents the abnormal sound that rubs between positive hinge and the hinge.The second, when the step rivet rotated, self-lubricating lining work plane directly contacted with step rivet flange face 4-3, reduces the friction of motion resistance, prevents the abnormal sound that rubs.
The pin-and-hole diameter of described hinge 2 and the external diameter basically identical of self-lubricating lining, and the flange at self-lubricating lining two ends and hinge 2 are close to.
The diameter of the step section that the diameter of described step rivet 4 is bigger is less than or equal to self-lubricating lining internal diameter, to guarantee the smooth and easy flexible of motion; The diameter of the step section that the diameter of step rivet 4 is less and the diameter basically identical of positive hinge pin aperture.
The length of the step section that the diameter of described step rivet 4 is bigger is more than or equal to the thickness of self-lubricating lining two ends flange and the thickness sum of hinge, to guarantee between riveted joint positive hinge in back and the self-lubricating lining not mutual extrusion.
During assembling, press-fiting self-lubricating lining 3 with the installation plug earlier is set in the pin-and-hole of hinge 2, re-use the flange plug and carry out flange, then, the hinge that installs the self-lubricating lining is connected with positive hinge 1 usefulness step rivet 4, regulate the squeeze riveter parameter, press, carry out the check of front shroud hinge dimensions and the flexible smooth and easy check of moving at last.The characteristics of this kind hinge arrangement are between the negative and positive hinge it is not the face face contact of traditional structure, but positive hinge contacts with 4-1, the 4-2 face of step rivet, assembling self-lubricating lining and flange on the hinge, the self-lubricating lining separates the negative and positive hinge, when the negative and positive hinge relatively rotates, contact with the lining work plane.Thereby less frictional resistance makes the switching motion smooth and easy, has no abnormal sound.
