Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to a riveting structure for an engine hood hinge. Background Technology

[0002] Traditional hood hinges are made by riveting body panels and hood panels together with pins. Their main function is to connect the body and the hood, ensuring the hood can move between closed and open positions. Because the gap between the body panels and hood panels is small during riveting, there is a risk of product scrapping during subsequent surface treatment. Therefore, improvements are needed. Utility Model Content

[0003] Therefore, it is necessary to provide a hood hinge riveting structure to address the problem that the traditional hood opening and closing hinge has a small gap when riveting the body panels and hood panels, which easily leads to the risk of product scrapping during later surface treatment.

[0004] This utility model provides an engine hood hinge riveting structure, comprising:

[0005] The cover leaf has a first through hole;

[0006] The body panel has a boss on the side near the hood panel, the boss has a second through hole coaxial with the first through hole, and the side away from the hood panel has an inner groove, the depth of which is the same as the height of the boss.

[0007] A pin passes through the first and second through holes, and one end is riveted to the body panel.

[0008] In one embodiment, a bushing is snapped into the first through hole.

[0009] In one embodiment, the bushing includes a washer portion, both ends of which have limiting portions, the outer diameter of which is larger than the diameter of the first through hole.

[0010] In one embodiment, the surface of the limiting part is provided with a V-shaped groove, and the outer wall of the pad ring part has an opening groove, which communicates with the V-shaped groove.

[0011] In one embodiment, the outer diameter of the boss is larger than the outer diameter of the limiting portion.

[0012] In one embodiment, the diameter of the first through hole is larger than the diameter of the second through hole.

[0013] The aforementioned engine hood hinge riveting structure, by adding a boss structure to the body panel of the engine hood opening and closing hinge, creates a certain gap between the hood panel and the body panel after riveting, preventing problems such as electrophoretic paint runs and adhesion during subsequent electroplating and electrophoretic treatments, thereby improving product performance.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this specification belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] The following is combined with Figures 1-4 This invention describes the engine hood hinge riveting structure.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, an engine hood hinge riveting structure includes a hood flap 100, a body flap 200, and a pin 300.

[0028] The cover 100 has a first through hole 110.

[0029] It should be noted that the cover 100 has threaded holes, and the cover 100 is connected to the engine hood with bolts.

[0030] The body panel 200 has a boss 220 on the side near the cover panel 100. The boss 220 has a second through hole 210, which is coaxial with the first through hole 110. The body panel 200 also has an inner groove 230 on the side away from the cover panel 100. The depth of the inner groove 230 is the same as the height of the boss 220.

[0031] It should be noted that the height of the boss 220 is 0.4mm, the gap between the cover leaf 100 and the body leaf 200 at the riveting position is 0.6mm, and the gap at other positions is 1.0mm.

[0032] The pin 300 passes through the first through hole 110 and the second through hole 210, and one end of the pin 300 is riveted to the body panel 200.

[0033] It should be noted that the body panel 200 is fixed to the vehicle body, and the hood panel 100 rotates around the pin 300, thereby realizing the opening and closing action of the engine hood.

[0034] The engine hood hinge riveting structure adds a boss 220 structure to the body panel 200 of the engine hood opening and closing hinge, so that the hood panel 100 and the body panel 200 have a certain gap after riveting, which prevents problems such as electrophoretic paint flow marks and adhesion during subsequent electroplating and electrophoretic treatment, thereby improving product performance.

[0035] In this embodiment, a bushing 400 is snapped into the first through hole 110. The bushing 400 can eliminate the errors generated during the processing of the cover 100 and the pin 300, thereby improving the stability of the riveting structure. At the same time, by adding a bushing 400 into the first through hole 110, the wear generated during the opening and closing process can be reduced, thus improving the service life.

[0036] In this embodiment, see Figure 4 The bushing 400 includes a washer portion 410, and both ends of the washer portion 410 have limiting portions 420. The outer diameter of the limiting portion 420 is larger than the diameter of the first through hole 110.

[0037] The washer ring 410 reduces wear between the pin 300 and the cover 100, and automatically compensates for machining errors between the pin 300 and the cover 100. The limiting part 420 confines the washer ring 410 within the first through hole 110, and also reduces wear between the cover 100 and the body panel 200 during opening and closing.

[0038] In this embodiment, the surface of the limiting part 420 is provided with a V-shaped groove 440, and the outer wall of the pad ring part 410 is provided with an opening groove 430, which communicates with the V-shaped groove 440.

[0039] By opening the slot 430 and the V-groove 440 on the bushing 400, it is convenient to assemble and disassemble the bushing 400, so as to facilitate the replacement of the bushing 400 as needed.

[0040] In this embodiment, the outer diameter of the boss 220 is larger than the outer diameter of the limiting part 420, so that the limiting part 420 near the side of the vehicle body 200 is always in contact with the boss 220, thereby making the limiting part 420 more evenly stressed and improving the service life of the limiting part 420.

[0041] In this embodiment, the diameter of the first through hole 110 is larger than the diameter of the second through hole 210.

[0042] It should be noted that, in order to enable relative rotation between the cover 100 and the body 200, the outer diameter of the end of the pin 300 connected to the cover 100 is larger than the outer diameter of the end connected to the body 200, thereby improving the stability of the connection between the cover 100 and the body 200.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
