Detailed description of the invention
Fig. 1 is the schematic diagram of the backdoor hinge of automobile according to an embodiment of the invention.Composition graphs 2 to Fig. 6, the backdoor hinge for automobile of the present embodiment comprises hinge base 10, bolt 20 and wedge metal ring 30, hinge base 10 has installing hole 11, bolt 20 is located in the installing hole 11 of hinge base 10, between the bar portion of bolt 20 and installing hole 11, there is radial clearance, wedge metal ring 30 is stamped in the radial clearance between the bar portion of bolt 20 and installing hole 11 by drop stamping technique, and wedge metal ring 30, hinge base 10 and bolt 20 are combined as a whole formula structure.
Show in Fig. 4 between the bar portion of bolt 20 and installing hole 11 and there is radial clearance A, by the radial clearance punching press wedge metal ring 30 between bolt 20 and hinge base 10, wedge metal ring 30 is blocked above-mentioned radial clearance, fundamentally avoids rainwater and flow into vehicle body from backdoor hinge.
It should be noted that, the temperature of drop stamping technique is generally 500 DEG C to 800 DEG C, and the technological temperature of drop stamping technique can make the inner surface of the external surface of wedge metal ring and installing hole 11 melt but not reach the stage making all the other material melts.The temperature of drop stamping technique also needs to change according to concrete material, can adjust within the specific limits.Integral structure cools again the morphosis being formed and do not have obvious border after referring to the contact portion material melts of two kinds of structures, wedge metal ring 30, hinge base 10 and bolt 20 are combined as a whole formula structure, refer to and form the structure not having obvious border after melting between wedge metal ring 30 and hinge base 10 and between wedge metal ring 30 and bolt 20, just can not leak after there is no gap like this.
As shown in Figure 2, the installed surface that the head of bolt 20 contacts with hinge base 10 is plane.Joint between the head of such bolt 20 and hinge base is more steady, to help when carrying out 30 drop stamping of wedge metal ring, and can the correct installation site of determination bolt 20 effectively.
See Fig. 3 and Fig. 5, wedge metal ring 30 is the outer rear flank reaching hinge base 10 in the bar portion of bolt from the inner side of hinge base 10 through installing hole 11, install to the bar portion of bolt from the outside of hinge base 10 with the sharp attitude cover towards installing hole 11 of the wedge of wedge metal ring 30, be then stamped in the radial clearance between the bar portion of bolt 20 and installing hole 11 by drop stamping technique.
The hinge base of the present embodiment is identical with existing selection with bolt, and wedge metal ring ring material is that intensity is less but the metal that plasticity is strong, so in the present embodiment, wedge metal ring 30 is made up of mild steel.As shown in Figure 6, the hinge base 10 of backdoor hinge is provided with pad 40, page plate 50, axle sleeve 60 and axle 70.
Present invention also offers a kind of embodiment of assembly method of the backdoor hinge for automobile, can be obtained the backdoor hinge of above-described embodiment by the assembly method of the present embodiment, see Fig. 7, this assembly method comprises the following steps:
S1: bolt 20 is worn in the installing hole 11 of hinge base 10, bar portion and installing hole 11 diameter of bolt 20 have radial clearance;
S2: by wedge metal ring 30 by the radial clearance between drop stamping technique punching press to the bar portion and the installing hole 11 of hinge base 10 of bolt 20, thus wedge metal ring 30, hinge base 10 and bolt 20 are combined as a whole formula structure.
By the backdoor hinge that this assembly method obtains, by the radial clearance punching press wedge metal ring 30 between bolt 20 and hinge base 10, wedge metal ring 30 is blocked above-mentioned radial clearance, fundamentally avoids rainwater and flow into vehicle body from backdoor hinge.
It should be noted that, the temperature of drop stamping technique is generally 500 DEG C to 800 DEG C, and the technological temperature of drop stamping technique can make the inner surface of the external surface of wedge metal ring and installing hole 11 melt but not reach the stage making all the other material melts.The temperature of drop stamping technique also needs to change according to concrete material, can adjust within the specific limits.Integral structure cools again the morphosis being formed and do not have obvious border after referring to the contact portion material melts of two kinds of structures, wedge metal ring 30, hinge base 10 and bolt 20 are combined as a whole formula structure, refer to and form the structure not having obvious border after melting between wedge metal ring 30 and hinge base 10 and between wedge metal ring 30 and bolt 20, just can not leak after there is no gap like this.
Preferably, the installed surface that the head of bolt 20 contacts with hinge base 10 is plane.Joint between the head of such bolt 20 and hinge base is more steady, to help when carrying out 30 drop stamping of wedge metal ring, and can the correct installation site of determination bolt 20 effectively.
Wedge metal ring 30 is the outer rear flank reaching hinge base 10 in the bar portion of bolt from the inner side of hinge base 10 through installing hole 11, install to the bar portion of bolt from the outside of hinge base 10 with the sharp attitude cover towards installing hole 11 of the wedge of wedge metal ring 30, be then stamped in the radial clearance between the bar portion of bolt 20 and installing hole 11 by drop stamping technique.
The hinge base of the present embodiment is identical with existing selection with bolt, and wedge metal ring ring material is that intensity is less but the metal that plasticity is strong, so in the present embodiment, wedge metal ring 30 is made up of mild steel.
The assembly method of the present embodiment is further comprising the steps of:
Pad 40, page plate 50, axle sleeve 60 and axle 70 are installed on hinge base 10.
It should be noted that, above-mentioned step pad 40, page plate 50, axle sleeve 60 and axle 70 are installed on hinge base 10, belong to mounting technology well known to those skilled in the art, part also belongs to part of the prior art, so repeat no more herein.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present invention is illustrate and described herein detailed, but, without departing from the spirit and scope of the present invention, still can directly determine or derive other modification many or amendment of meeting the principle of the invention according to content disclosed by the invention.Therefore, scope of the present invention should be understood and regard as and cover all these other modification or amendments.
