Description

Technical Field

[0001] The present invention relates to a door hinge mounting member for a side outer panel of a vehicle, and more particularly to a door hinge mounting member for a side outer panel that can structurally ensure rigidity and prevent damage. Background Art

[0002] Due to the recent diverse demands of customers, a variety of vehicles are being produced in small quantities. Therefore, it has become increasingly difficult to apply side outer panels made of steel and requiring excessive initial mold investment costs to vehicle bodies.

[0003] Therefore, as an alternative to steel side outer panels, side outer panels made of composite materials and having lower initial mold investment costs are being studied.

[0004] However, side outer panels made of composite materials have problems in that they are insufficient in rigidity compared to side outer panels made of steel materials, and portions of the side outer panels where stress is concentrated (eg, door hinge mounting members where door hinges are mounted) are easily damaged.

[0005] The information contained in this Background of the Invention section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgment or any form of suggestion that this information forms the prior art already known to a person skilled in the art. Summary of the Invention

[0006] Various aspects of the present invention are directed to providing a door hinge mounting member for a side outer panel of a vehicle, which is configured to be formed of a material requiring lower initial investment cost than steel and ensure the same level of rigidity as a case of using steel.

[0007] Therefore, various aspects of the present invention provide a door hinge mounting member for a side outer panel of a vehicle, which includes: a mounting plate portion on which a door hinge is mounted; and a variable plate portion, which is integrally formed at an edge portion of the mounting plate portion, extends along the circumference of the mounting plate portion, and gradually decreases in thickness toward a direction away from the edge portion in the mounting plate portion.

[0008] The door hinge mountings for the side outer panels have the following features.

[0009] The variable plate portion may include: an upper variable portion having a thickness that decreases upward; a lower variable portion that is arranged below the upper variable portion and has a thickness that decreases downward; a front variable portion that extends from the front end portion of the upper variable portion and the front end portion of the lower variable portion and has a thickness that decreases forward; and a rear variable portion that extends from the rear end portion of the upper variable portion and the rear end portion of the lower variable portion and has a thickness that decreases rearward.

[0010] The mounting plate portion may be a flat plate having a uniform thickness throughout.

[0011] An outer surface of the variable plate portion may be flat relative to an outer surface of the mounting plate portion, and an inner surface of the variable plate portion may be inclined relative to an inner surface of the mounting plate portion.

[0012] The mounting plate portion may include at least one hinge fastening hole for mounting a door hinge and at least one position adjusting protrusion for adjusting a position of the at least one hinge fastening hole.

[0013] At least one position adjustment boss may be assembled to at least one position adjustment hole formed in the side outer reinforcement, and the side outer reinforcement may be a plate member coupled with the side outer panel.

[0014] At least one spacer may be disposed in at least one hinge fastening hole of the mounting plate portion, and at least one door hinge mounted on an outer surface of the mounting plate portion may be spaced apart from the outer surface of the mounting plate portion by the at least one spacer. The door hinge may be mounted to the mounting plate portion using a hinge mounting bolt passing through the hinge fastening hole.

[0015] At least one spacer may include: a flat spacer outer plate portion, which is arranged on the outer surface of the mounting plate portion; a flat spacer inner plate portion, which is arranged on the inner surface of the mounting plate portion; and a cylindrical spacer central plate portion, which extends from the inner periphery of the spacer inner plate portion to the inner periphery of the spacer outer plate portion and is arranged to pass through multiple hinge fastening holes.

[0016] The variable plate portion may include a plurality of beads spaced apart along a circumference thereof, and the beads may protrude from an inner surface of the variable plate portion.

[0017] The door hinge mounting may be part of a side outer panel, and the side outer panel including the door hinge mounting may be formed from a plastic composite material.

[0018] According to the means for solving the above-mentioned problems, various aspects of the present invention provide the following main effects.

[0019] First, the door hinge mounting member of the side outer panel adopts a variable thickness structure to prevent the reduction in rigidity caused by the plastic composite material of the side outer panel.

[0020] Second, the door hinge mounting member of the side outer panel can ensure the same level of rigidity as that formed of steel in the related art.

[0021] Third, the mounting plate portion of the door hinge mounting member includes spacers that disperse stress concentrated around the hinge fastening hole of the mounting plate portion by the door hinge, hinge mounting bolts, and hinge mounting nuts, thereby preventing damage due to the stress.

Figure 9 It is along Figure 8Cross-sectional view obtained along line CC.

[0040] As in Figure 1 As shown in FIG, a side outer panel 1 for a vehicle has a door hinge mounting member 10 formed with a hinge fastening hole 111 for mounting a door hinge (see FIG. Figure 8 and Figure 9 3).

[0041] The door hinge 3 is configured to support a pivoting motion for opening / closing a vehicle side door. In the side outer panel 1, the door hinge 3 is installed at two or more locations to support one side door.

[0042] The side outer panel 1 may have a door hinge mounting member 10 at a position where each door hinge 3 is mounted.

[0043] The door hinge mounting member 10 is a part of the side outer panel 1 , and is a portion of the side outer panel 1 to which the door hinge 3 is mounted.

[0044] As in Figure 2 、 Figure 3 and Figure 4 As shown in FIG, a door hinge mounting member 10 is provided in the form of a plate member having a variable thickness in certain areas to increase its rigidity.

[0045] The door hinge mounting member 10 includes a mounting plate portion 110 on which the door hinge 3 is mounted and arranged, and a variable plate portion 120 integrally provided at an edge portion of the mounting plate portion 110 .

[0046] The mounting plate portion 110 includes a plurality of hinge fastening holes 111 for mounting the door hinge 3 and may be formed as a flat plate having a uniform thickness as a whole. For example, the mounting plate portion 110 may be formed as a flat plate having an approximately quadrilateral shape.

[0047] The mounting plate portion 110 may be set to have a thickness thicker than other regions of the side outer panel 1 except for the door hinge mounting member 10. More specifically, the side outer panel 1 may be configured such that the mounting plate portion 110, which is a region surrounded by the variable panel portion 120, is set to be thicker than an outer region of the variable panel portion 120 surrounding the variable panel portion 120.

[0048] The variable plate portion 120 is provided at an edge portion of the mounting plate portion 110 so as to extend in a circumferential direction of the mounting plate portion 110. The variable plate portion 120 seamlessly extends in a circumferential direction of the mounting plate portion 110 so that stress is uniformly applied, and is provided at the edge portion of the mounting plate portion 110 in a ring form.

[0049] The variable plate portion 120 has a thickness that decreases in a direction away from an edge portion of the mounting plate portion 110. That is, the variable plate portion 120 has a thickness that gradually decreases toward the outside of the mounting plate portion 110. In this case, the thickness of the variable plate portion 120 is a thickness in the left-right direction of the vehicle body.

[0050] The thickness of the variable plate portion 120 may decrease at a given ratio according to a distance from an edge portion of the mounting plate portion 110. Therefore, the variable plate portion 120 may include a surface having a given gradient with respect to the mounting plate portion 110.

[0051] Specifically, the variable plate portion 120 may include an upper variable portion 121 , a lower variable portion 122 , a front variable portion 123 , and a rear variable portion 124 .

[0052] The upper variable portion 121 is a portion extending from the upper edge portion of the mounting plate portion 110 and has a thickness in the left-right direction that decreases upward from the upper edge portion of the mounting plate portion 110. The thickness of the upper variable portion 121 may decrease at a ratio set according to the distance from the upper edge portion of the mounting plate portion 110.

[0053] The lower variable portion 122 extends from the lower edge of the mounting plate portion 110 and has a thickness in the left-right direction that decreases downward from the lower edge of the mounting plate portion 110. The thickness of the lower variable portion 122 may decrease at a ratio given by the distance from the lower edge of the mounting plate portion 110. The lower variable portion 122 is disposed below the upper variable portion 121, and the mounting plate portion 110 is disposed between the upper variable portion 121 and the lower variable portion 122.

[0054] The front variable portion 123 is a portion extending from the front edge portion of the mounting plate portion 110, and has a thickness in the left-right direction that decreases forward from the front edge portion of the mounting plate portion 110. The thickness of the front variable portion 123 may decrease at a given ratio according to the distance from the front edge portion of the mounting plate portion 110. The front variable portion 123 may be integrally connected to the front end portion of the upper variable portion 121 and the front end portion of the lower variable portion 122, and extend from the front end portion of the upper variable portion 121 to the front end portion of the lower variable portion 122.

[0055] The rear variable portion 124 extends from the rear edge of the mounting plate portion 110 and has a thickness in the left-right direction that decreases rearward from the rear edge of the mounting plate portion 110. The thickness of the rear variable portion 124 may decrease at a given ratio according to the distance from the rear edge of the mounting plate portion 110. The rear variable portion 124 may be integrally connected to the rear end portions of the upper variable portion 121 and the lower variable portion 122, and extend from the rear end portions of the upper variable portion 121 and the lower variable portion 122. The rear variable portion 124 is disposed rearward of the front variable portion 123, with the mounting plate portion 110 disposed between the rear variable portion 124 and the front variable portion 123.

[0056] The upper variable portion 121 and the lower variable portion 122, as well as the front variable portion 123 and the rear variable portion 124, may have the same thickness so that stress is uniformly applied by the door hinge 3 supporting the vehicle side door, and the thickness of these variable portions may be reduced at the same ratio. The side door is coupled to the mounting plate portion 110 via the door hinge 3.

[0057] To ensure the aesthetic appearance of the side outer panel 1, the variable panel portion 120 configured as described above may have an outer surface that extends flatly without an inclination from the outer surface of the mounting panel portion 110, and an inner surface that extends at a given inclination from the inner surface of the mounting panel portion 110. That is, the outer surface of the variable panel portion 120 may be flat relative to the outer surface of the mounting panel portion 110, while the inner surface of the variable panel portion 120 may be inclined relative to the inner surface of the mounting panel portion 110.

[0058] Here, the outer surface of the variable plate portion 120 is the surface of the variable plate portion 120 facing the outside of the vehicle body, and the inner surface of the variable plate portion 120 is the surface of the variable plate portion 120 facing the inside of the vehicle body. Similarly, the outer surface of the mounting plate portion 110 is the surface of the mounting plate portion 110 facing the outside of the vehicle body, and the inner surface of the mounting plate portion 110 is the surface of the mounting plate portion 110 facing the inside of the vehicle body.

[0059] Furthermore, in order to further increase the rigidity of the door hinge mount 10 , the variable plate portion 120 may include a plurality of variable beads 125 .

[0060] The beads 125 may protrude from the inner surface of the variable plate portion 120 and be spaced apart along the circumference of the variable plate portion 120. The beads 125 may protrude from the inclined inner surface of the variable plate portion 120 and extend up to the same height as the inner surface of the mounting plate portion 110.

[0061] The beads 125 may be selectively provided on one side of the variable plate portion 120. For example, as in Figure 2As shown in , the bead 125 can be integrally provided on the front variable portion 123 and arranged along its upper and lower directions. When the bead 125 protrudes from the front variable portion 123, the bead 125 can extend from the edge portion of the mounting plate portion 110 to the curved surface 20 of the side outer panel 1.

[0062] The curved surface 20 is a portion of the side outer panel 1 and is provided in front of the door hinge mounting member 10. The curved surface 20 is a panel portion provided perpendicular to the mounting plate portion 110. The curved surface 20 may be provided close to or adjacent to a front edge portion of the front variable portion 123.

[0063] Therefore, the case in which the bead 125 is provided at the front variable portion 123 of the variable plate part 120 and extends up to the curved surface 20 to be connected to the curved surface 20 may more effectively increase the rigidity of the door hinge mount 10 than other cases.

[0064] The increased rigidity of the door hinge mount 10 has the advantage of facilitating improved sagging of the side door fastened to the mounting plate portion 110 and preventing later deformation of the door hinge mount 10 .

[0065] Meanwhile, the hinge fastening holes 111 of the mounting plate portion 110 can be arranged in various directions according to the shape of the door hinge 3 mounted on the mounting plate portion 110. For example, the hinge fastening holes 111 can be arranged front to back or up and down in the mounting plate portion 110.

[0066] It is necessary to adjust the position of the hinge fastening hole 111 against the side outer reinforcement 2 coupled to the side outer panel 1 .

[0067] As in Figure 6 As shown in , the side outer panel 1 is coupled to the side outer reinforcement 2 using an adhesive, and it takes about three to four hours for the adhesive to fully harden. During vehicle body assembly, the side outer panel 1 is usually transported to another assembly line before the adhesive is fully hardened.

[0068] Therefore, in order to restrict the position of the hinge fastening holes 111 relative to the side outer reinforcement 2 when the side outer panel 1 is moved during vehicle body assembly, the hinge fastening holes 111 need to be fixed to prevent them from deviating from the designated position during the curing of the adhesive. This is because the side outer reinforcement 2 also has a reinforcement hinge fastening hole 22 for mounting the door hinge 3.

[0069] To fix the position of the hinge fastening hole 111 relative to the side outer reinforcement 2 , or to fix the position of the hinge fastening hole 111 relative to the reinforcement hinge fastening hole 22 of the side outer reinforcement 2 , the mounting plate portion 110 may include a plurality of position adjustment protrusions 112 .

[0070] The position adjustment protrusion 112 may protrude vertically from the inner surface of the mounting plate portion 110. In the case where the mounting plate portion 110 has only one position adjustment protrusion 112, the side outer panel 1 can rotate relative to the side outer reinforcement 2. Therefore, the mounting plate portion 110 may include at least two or more position adjustment protrusions 112 formed thereon.

[0071] As in Figure 7 As shown in FIG, when the side outer panel 1 and the side outer reinforcement 2 are coupled, the position adjustment protrusion 112 is assembled through the plurality of position adjustment holes 21 formed in the side outer reinforcement 2. When coupled with the side outer panel 1, the side outer reinforcement 2 is provided on the inner surface side of the side outer panel 1.

[0072] The side outer reinforcement 2 is a plate member for reinforcing the side outer panel 1 formed of a plastic composite material, and is formed of, for example, a steel material.

[0073] In addition, as in Figure 4 As shown in FIG, the mounting plate portion 110 has a spacer 130 provided in the hinge fastening hole 111, the spacer 130 being formed of a steel material and preventing damage to the mounting plate portion 110.

[0074] When molding the side outer panel 1, the spacer 130 is attached to the mounting plate portion 110 in a manner such that the spacer 130 is assembled into the hinge fastening hole 111. More specifically, the spacer 130 is placed in a mold for injection molding the side outer panel 1, and the side outer panel 1 is molded together with the spacer 130 inserted into the mold. Thus, the spacer 130 can be integrally attached to the hinge fastening hole 111 of the mounting plate portion 110.

[0075] As in Figure 4 and Figure 5 As shown in , each spacer 130 may include a spacer outer plate portion 131 , a spacer inner plate portion 132 , and a spacer central plate portion 133 .

[0076] The spacer outer plate portion 131 may be formed in a flat plate shape and provided in a layered manner on the outer surface of the mounting plate portion 110. The spacer outer plate portion 131 may be formed in an annular flat plate with a hole in the center. The center portion of the spacer outer plate portion 131 may have a hole in the shape of the hinge fastening hole 111.

[0077] The spacer inner plate portion 132 may be formed in a flat plate shape and disposed in a layered manner on the inner surface of the mounting plate portion 110. The spacer inner plate portion 132 may be formed as an annular flat plate with a central opening. The central portion of the spacer inner plate portion 132 may have a hole in the shape of the hinge fastening hole 111. The spacer inner plate portion 132 may have the same shape as the spacer outer plate portion 131, and the spacer inner plate portion 132 and the spacer outer plate portion 131 may be symmetrical with respect to the spacer central plate portion 133.

[0078] The spacer central plate portion 133 may be formed into a cylindrical shape extending integrally from the inner periphery of the spacer inner plate portion 132 to the inner periphery of the spacer outer plate portion 131 , and be arranged in the hinge fastening hole 111 in a state where the spacer central plate portion 133 passes through the hinge fastening hole 111 .

[0079] When molding the side outer panel 1, the spacer 130 configured in this manner can be joined and fixed to the mounting plate portion 110. The spacer outer plate portion 131 can be joined and fixed to the outer surface of the mounting plate portion 110 with its inner periphery abutting the hinge fastening hole 111. The spacer inner plate portion 132 can be joined and fixed to the inner surface of the mounting plate portion 110 with its inner periphery abutting the hinge fastening hole 111. The spacer central plate portion 133 can be joined and fixed to the inner periphery of the mounting plate portion 110 around the hinge fastening hole 111.

[0080] In this manner, the spacer 130 is joined to the mounting plate portion 110 in a state where the spacer 130 is assembled to the hinge fastening hole 111 , which makes it possible to prevent damage to the mounting plate portion 110 and ensure sealing performance of the mounting plate portion 110 .

[0081] Without applying the spacer 130 to the mounting plate portion 110 , the mounting plate portion 110 may be easily damaged due to the concentration of stress input through the door hinge 3 (which is formed of a steel material) around the hinge fastening hole 111 .

[0082] As in Figure 9 As shown in the figure, when the door hinge 3 is arranged on the outer surface of the mounting plate part 110, which is separated from the door hinge 3 by the thickness of the spacer outer plate part 131, the spacer 130 supports the door hinge 3 and structurally strengthens the surrounding area of ​​the hinge fastening hole 111 of the mounting plate part 110.

[0083] The spacer 130 prevents the door hinge 3 and the hinge mounting bolt 31 from directly contacting the mounting plate portion 110 , thereby preventing stress input through the door hinge 3 from concentrating around the hinge fastening hole 111 and dispersing stress input through the hinge mounting bolt 31 .

[0084] As in Figure 8and Figure 9 As shown in FIG, the hinge mounting bolt 31 fastens the door hinge 3 to the mounting plate portion 110 together with the hinge mounting nut 32. In a state where the hinge mounting bolt 31 passes through the hinge fastening hole 111, the hinge mounting bolt 31 is fastened by the hinge mounting nut 32 provided on the inner surface side of the mounting plate portion 110.

[0085] Furthermore, the door hinge mounting member 10 ensures sealing performance of the mounting plate portion 110 via the spacer 130. This reduces the cost of corrosion protection for the vehicle body's side inner panel and reduces noise intrusion. Although not shown, the side inner panel is coupled to the side outer panel 1 and is positioned further inward of the vehicle body than the side outer panel 1 and the side outer reinforcement 2.

[0086] As described above, the door hinge mounting member 10 adopts a variable thickness structure to prevent a decrease in rigidity due to its plastic composite material. The door hinge mounting member 10 includes a spacer 130 that disperses stress concentrated around the hinge fastening hole 111 by the door hinge 3, the hinge mounting bolt 31, and the hinge mounting nut 32, thereby preventing damage caused by the stress.

[0087] The side outer panel 1 having the door hinge mounting member 10 is molded from a plastic composite material, which requires a lower initial investment than conventional steel materials. This reduces costs while ensuring the same level of rigidity as a door hinge mounting member formed from a steel side outer panel. Furthermore, the rigidity of the door hinge mounting member 10 is increased compared to a door hinge mounting member having a uniform thickness as a whole without a distinct mounting plate portion and a variable plate portion.
