Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority to Korean Patent Application No. 10-2023-0079885, filed on Jun. 21, 2023, which is hereby incorporated by reference in its entirety. Technical Field

[0003] The present invention relates to a door module plate for a vehicle, and more particularly, to a door module plate for a vehicle capable of ensuring structural rigidity and improving safety and reliability. Background Art

[0004] In recent years, as the importance of environmental issues has become increasingly prominent, the use of environmentally friendly materials has been required in various ways. In the field of vehicles, the use of recycled materials such as recycled plastics is increasing.

[0005] However, since recycled plastic is processed by applying heat thereto, it is difficult to ensure sufficient physical properties such as mechanical strength. For current reasons, it is difficult to actively use recycled plastic for vehicle parts because the mechanical strength of these parts needs to reach a predetermined level or higher to ensure the safety of passengers.

[0006] Ordinary door templates for vehicles are manufactured by using a material made by mixing polymer resin and short glass fiber reinforced composite polypropylene (PP-SGF) material (reinforced by glass fiber) to improve mechanical strength. If the main material of the door template is changed to recycled plastic, it is difficult to ensure that the door template has sufficient mechanical strength.

[0007] Therefore, various studies have been conducted recently to manufacture door panels using environmentally friendly recycled materials while ensuring mechanical strength, but the research results are still insufficient. Therefore, it is necessary to develop a technology that can manufacture door panels using environmentally friendly recycled materials while ensuring mechanical strength.

[0008] 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 constitutes the prior art already known to a person skilled in the art.

[0042] Reference will now be made in detail to various embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments of the present invention, it should be understood that this specification is not intended to limit the present invention to those exemplary embodiments of the present invention. On the other hand, the present invention is intended to cover not only the exemplary embodiments of the present invention, but also various alternatives, variants, equivalents and other embodiments that may be included within the spirit and scope of the present invention as defined by the appended claims.

[0043] Hereinafter, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0044] However, the technical spirit of the present invention is not limited to the various exemplary embodiments described herein, and can also be implemented in various different forms. At least one constituent element in the exemplary embodiments of the present invention can be selectively combined and replaced so as to be used within the scope of the technical spirit of the present invention.

The meanings of commonly used terms (such as terms defined in dictionaries) may be interpreted in light of the contextual meanings of the relevant technology.

[0046] Furthermore, the terms used in the exemplary embodiments of the present invention are for explaining the embodiments rather than for limiting the present invention.

[0047] In the present specification, unless otherwise specified, a singular form may also include a plural form. The expression "at least one (or one or more) of A, B and C" may include one or more of all combinations of A, B and C.

[0048] Furthermore, terms such as first, second, A, B, (a), and (b) may be used to describe constituent elements of exemplary embodiments of the present invention.

[0049] These terms are used only to distinguish one constituent element from another constituent element, and the nature, order or sequence of the constituent elements is not limited by these terms.

[0050] In addition, when a constituent element is described as being “connected,” “coupled” or “attached” to another constituent element, the one constituent element may be directly connected, coupled or attached to the other constituent element or connected, coupled or attached to the other constituent element with another constituent element interposed therebetween.

[0051] In addition, the expression "one component is disposed or arranged above (upper) or below (lower) another component" includes not only the case where the two components are directly in contact with each other, but also the case where one or more other components are disposed or arranged between the two components. The expression "above (upper) or below (lower)" may refer to a downward direction as well as an upward direction based on one component.

[0052] refer to Figures 1 to 7 A door template 10 for a vehicle includes: a plate body 100, which is arranged to correspond to a door of the vehicle; a mounting portion 110, which is arranged at an edge portion of the plate body 100 and fastened to a fastening member; an edge groove 120, which is arranged at an edge portion of the plate body 100; and a reinforcing rib 130, which protrudes integrally from an inner surface of the edge groove 120.

[0053] This is to ensure the structural rigidity of the door template 10 for the vehicle and to improve the safety and reliability of the door template 10 .

[0054] That is, the main material of the door template can be changed to recycled plastic, which is an environmentally friendly material. However, since the recycled plastic is processed by applying heat thereto, it is difficult to ensure sufficient physical properties (such as mechanical strength). For this reason, it is difficult to ensure that the door template has sufficient mechanical strength.

[0055] In contrast, according to the exemplary embodiment of the present invention, the reinforcing rib 130 is integrally provided on the inner surface of the groove 120. Therefore, it is possible to obtain advantageous effects of ensuring the structural rigidity of the door template 10 and improving the safety and reliability of the door template 10.

[0056] According to the exemplary embodiment of the present invention, even if the main material of the door template 10 is changed to recycled plastic, which is an environmentally friendly material, the edge portion of the door template 10 (on which the sealing member 200 is accommodated) can be ensured to have sufficient mechanical strength. Therefore, the advantageous effects of reducing manufacturing costs and improving manufacturing efficiency of the door template 10 can be obtained.

[0057] The plate body 100 is disposed to correspond to a door of a vehicle. The plate body 100 and an inner panel 300 for a vehicle door (eg, an inner panel made of a metal material) together constitute a door template 10 for a vehicle.

[0058] For example, the plate body 100 may be provided to have an approximately quadrilateral plate shape corresponding to a vehicle door.

[0059] The plate body 100 may include a plurality of mounting slots 140 for mounting accessories of a vehicle door.

[0060] The number of mounting slots 140, the positions of mounting slots 140, and the types of accessories installed in mounting slots 140 can be variously changed according to the required conditions and design specifications. The present invention is not restricted or limited by the number of mounting slots 140, the positions of mounting slots 140, and the types of accessories installed in mounting slots 140.

[0061] For example, various types of accessories such as a motor, a speaker, and a window regulator for moving a window glass upward or downward may be installed in the mounting groove 140 .

[0062] refer to Figures 2 to 6 , the mounting portion 110 is provided at an edge portion of the board body 100 so that a fastening member for fastening the board body 100 and the inner panel 300 is fastened to the mounting portion 110 .

[0063] The mounting portion 110 defines a space in which a fastening member for fastening the board body 100 to the inner board 300 is arranged. For example, the mounting portion 110 may protrude from the front surface of the board body 100 and include a fastening hole (or fastening groove) to which a fastening bolt is fastened.

[0064] The mounting portion 110 may be provided as a plurality of mounting portions 110 spaced apart from each other along an outer edge portion of the board body 100 to increase a coupling force (fastening force) between the board body 100 and the inner panel 300 .

[0065] The number of mounting portions 110 and the spacing distance between mounting portions 110 may be variously changed according to required conditions and design specifications. The present invention is not restricted or limited by the number of mounting portions 110 and the spacing distance between mounting portions 110.

[0066] According to an exemplary embodiment of the present invention, the mounting portions 110 may be spaced apart from each other at a predetermined spacing distance along the outer edge portion of the board body 100. According to an exemplary embodiment of the present invention, a plurality of mounting portions may be spaced apart from each other at irregular spacing distances along the outer edge portion of the board body.

[0067] For reference, when the number of mounting portions 110 increases, the sealing between the plate body 100 and the inner plate 300 may be improved. However, if the number of mounting portions 110 increases too much, the manufacturing efficiency is inevitably reduced and the manufacturing time is increased. Therefore, the number of mounting portions 110 and the spacing distance between the mounting portions 110 may be set according to the sealing and manufacturing efficiency. For example, the mounting portions 110 may be provided on the central portion and the edge portion of the plate body 100 so as to be spaced apart from each other.

[0068] According to an exemplary embodiment of the present invention, a spacing distance L between adjacent mounting portions 110 may be defined as 100 mm to 250 mm.

[0069] That is, when the spacing distance L between adjacent mounting portions 110 is shorter than 100 mm or longer than 250 mm, the coupling force (fastening force) applied by the fastening member gradually decreases toward the center portion between the adjacent mounting portions 110. For this reason, the inner panel 300 and the plate body 100 may be separated from each other. If the plate body 100 and the inner panel 300 are separated from each other at the center portion between the adjacent mounting portions 110, water leakage may occur, which may cause defects in the door template for the vehicle. Therefore, the spacing distance L between the adjacent mounting portions 110 may be defined as 100 mm to 250 mm.

[0070] [Table 1]

[0071] Spacing distance between mounting parts 110 (mm) Separation interval (mm) 135.77 2 140.31 2 188.13 2.5 192.71 3 202.57 3 203.3 3 217.31 3 225.25 3 226.92 3.5 239.11 3.5

[0072] For reference, Table 1 shows the separation interval of the inner plate 300 from the plate body 100 relative to the spacing distance between adjacent mounting portions 110 according to an embodiment of the present invention. For example, the plate body 100 may have a width of 801.9 mm and a height of 533.57 mm. A total of ten mounting portions 110 may be provided along the peripheral edge. Referring to Table 1, it can be seen that as the distance between the mounting portions 110 increases, the separation interval also tends to increase.

[0073] In the exemplary embodiment of the present invention shown and described above, an embodiment in which the spacing distance between adjacent mounting portions 110 is defined as 100 mm to 250 mm has been described. However, the spacing distance between adjacent mounting portions 110 may vary according to the overall size of the board body 100. The present invention is not restricted or limited by the spacing distance.

[0074] The edge groove 120 is provided at an edge portion (eg, the outermost edge portion) of the plate body 100 to define a space in which the sealing member 200 (eg, sealing foam) is inserted and fixed.

[0075] According to an exemplary embodiment of the present invention, the edge groove 120 may be provided between the adjacent mounting portions 110 (a spacing distance portion defined between the adjacent mounting portions).

[0076] The edge groove 120 may be continuously disposed between adjacent mounting portions 110 to have an approximately continuous band shape along the edge portion of the plate body 100. According to another exemplary embodiment of the present invention, a plurality of edge grooves may be disposed between adjacent mounting portions and spaced apart from each other.

[0077] According to an exemplary embodiment of the present invention, a door template 10 for a vehicle may include a sealing member 200 accommodated (installed) in an edge groove 120 .

[0078] The sealing member 200 is used to seal the gap between the plate body 100 and the inner plate 300. The present invention is not restricted or limited by the material and properties of the sealing member 200.

[0079] For example, a typical sealing foam may be used as the sealing member 200 .

[0080] According to an exemplary embodiment of the present invention, the depth D of the edge groove 120 may be defined as 2.0 mm or less, and the width W of the edge groove 120 may be defined as 6.0 mm or less.

[0081] That is, the depth D and the width W of the edge groove 120 may be increased in proportion to the size of the plate body 100 and the diameter of the sealing member 200. However, when the depth D and the width W of the edge groove 120 are out of range (when the depth of the edge groove is greater than 2.0 mm and the width W of the edge groove is greater than 6.0 mm), the mechanical strength of the edge portion of the plate body 100 may be reduced, and the effect of improving the sealing property by increasing the diameter of the sealing member 200 is not high. Therefore, the depth D of the edge groove 120 may be limited to 2.0 mm or less, and the width W of the edge groove 120 may be limited to 6.0 mm or less.

[0082] For reference, the size of the sealing member 200 is slightly larger than the size of the edge groove 120. When the sealing member 200 is fixedly inserted into the edge groove 120, the elasticity of the sealing member 200 can press the inner panel 300 and the panel body 100 and seal the portion between the inner panel 300 and the panel body 100, thereby providing sealing for the door template 10 for a vehicle and effectively preventing water leakage.

[0083] The reinforcement rib 130 integrally protrudes from the inner surface of the edge groove 120 .

[0084] The reinforcement rib 130 integrally protrudes from the bottom surface of the edge groove 120 facing the inner panel 300 .

[0085] As described above, in the exemplary embodiment of the present invention, the reinforcing rib 130 is provided on the inner surface of the edge groove 120. Therefore, the mechanical strength of the edge portion of the plate body 100 can be enhanced (improved) by squeezing (additionally compressing) the sealing member 200 between the inner plate 300 and the plate body 100, and the sealing performance of the sealing member 200 can be improved.

[0086] That is, the reinforcing rib 130 protruding from the inner surface of the edge groove 120 can press the sealing member 200, thereby reducing the separation interval between the inner plate 300 and the plate body 100. By increasing the pressing force on the sealing member 200 at the central portion between the adjacent mounting portions 110, the separation interval can be effectively eliminated.

[0087] The reinforcing rib 130 may have various structures and shapes according to required conditions and design specifications. The present invention is not restricted or limited by the structure and shape of the reinforcing rib 130.

[0088] According to an exemplary embodiment of the present invention, the reinforcing rib 130 may be integrated with the plate body 100 and include an outer peripheral surface having a curvature.

[0089] In the exemplary embodiment of the present invention, the height H of the reinforcing rib 130 is lower than the height of the plate body 100 .

[0090] In an exemplary embodiment of the present invention, the height of the reinforcing rib 130 is lower than the height D of the edge groove 120 .

[0091] According to an exemplary embodiment of the present invention, when the plate body 100 is formed (eg, by extrusion), the reinforcing rib 130 may be integrally formed with the plate body 100 together with the edge groove 120 .

[0092] As described above, in the exemplary embodiment of the present invention, the plate body 100 and the reinforcing rib 130 are formed together through a single process (extrusion). Therefore, a separate process for forming the reinforcing rib 130 can be omitted. Therefore, the advantageous effects of simplifying the manufacturing method and improving the manufacturing efficiency can be obtained.

[0093] Furthermore, according to an exemplary embodiment of the present invention, a reinforcing rib 130 may be provided on an inner surface of the edge groove 120 to reinforce (improve) the mechanical strength of the edge portion of the plate body 100 .

[0094] According to an exemplary embodiment of the present invention, the reinforcement rib 130 may satisfy Expression 1 and Expression 2 below.

[0095] [Expression 1]

[0096] 0.26D <H<0.85D

[0097] [Expression 2]

[0098] H∝L

[0099] Here, H represents the height of the reinforcing rib 130 , D represents the depth of the groove 120 , and L represents the spacing distance between adjacent mounting portions 110 .

[0100] According to an exemplary embodiment of the present invention, the height H of the reinforcement rib 130 may be defined as 0.5 mm to 1.5 mm.

[0101] The height H of the reinforcing rib 130 is determined in the range of (0.5 mm to 1.5 mm), and the height may vary according to Expression 1 within the depth range of the edge groove 120 .

[0102] For reference, the height H of the reinforcing rib 130 may be obtained from an experiment in which the height is changed according to the depth D of the edge groove 120 .

[0103] According to an exemplary embodiment of the present invention, the height H of the reinforcing rib 130 may be defined as an end portion of a spacing distance portion defined between adjacent mounting portions 110 (see FIG. Figure 6 E) to the center of the spacing distance section (see Figure 6 C) direction (H2>H1).

[0104] In addition, according to an exemplary embodiment of the present invention, the width W of the reinforcing rib 130 may be defined as an end portion of a spacing distance portion defined between adjacent mounting portions 110 (see FIG. Figure 6 E) to the center of the spacing distance section (see Figure 6 It gradually increases in the direction of C).

[0105] According to Expression 2, the height H of the reinforcing rib 130 may increase as the distance between the mounting portions 110 increases. The height H of the reinforcing rib 130 may increase to about 85% of the maximum depth of the edge groove 120.

[0106] In an exemplary embodiment of the present invention, the reinforcing rib 130 may press the sealing member 200 (a sealing member pressing between the inner panel and the panel body) to seal a portion between the panel body 100 and the inner panel 300 .

[0107] This is based on the fact that when the spacing distance between adjacent mounting portions 110 increases, the separation between the plate body 100 and the inner panel 300 also increases when fastening the plate body 100 and the inner panel 300. As the fastening force applied by the mounting portions 110 decreases, separation may occur at the center portion between adjacent mounting portions 110.

[0108] However, according to the exemplary embodiment of the present invention, the height and width of the reinforcing rib 130 gradually increase in a direction from one end portion of the spacing distance portion defined between the adjacent mounting portions 110 to the central portion of the spacing distance portion, so that the reinforcing rib 130 defines the highest height and the maximum width at the central portion between the adjacent mounting portions 110. Therefore, the sealing member 200 can be squeezed to the maximum extent at the portion where the separation increases, thereby effectively preventing water leakage caused by the separation between the plate body 100 and the inner plate 300.

[0109] According to an exemplary embodiment of the present invention, the reinforcing rib 130 is formed to include an outer surface (peripheral surface) having a curvature. Therefore, the outer surface of the reinforcing rib 130 includes the above-mentioned curvature, so it is possible to obtain the advantageous effect of preventing the sealing member 200 from being damaged when the sealing member 200 is squeezed and more effectively suppressing the possibility of water leakage.

[0110] For example, the outer surface of the reinforcing rib 130 may be provided in an approximately semicircular shape having a radius of curvature of 0.5R to 10R. Alternatively, the reinforcing rib 130 may be provided in a trapezoidal shape including a curved edge portion, or in other shapes.

[0111] As described above, the reinforcing rib 130 may be disposed inside the edge groove 120 to increase the mechanical strength of the board body 100 .

[0112] According to an exemplary embodiment of the present invention, the board body 100 may be made of recycled plastic (recycled plastic is used as a main material).

[0113] However, when the board body 100 includes recycled plastic, the mechanical strength of the board body 100 may be reduced. Since the fastening member is fastened to the mounting portion 110 provided at the edge portion of the board body 100, the edge portion of the board body 100 may be easily damaged due to the concentration of stress applied when fastening the fastening member.

[0114] On the contrary, according to the exemplary embodiment of the present invention, the reinforcing rib 130 is provided on the inner surface of the edge groove 120 (the edge groove 120 is provided at the edge portion of the plate body 100), so that it is possible to increase the mechanical strength of the edge portion of the plate body 100. Therefore, it is possible to obtain the following advantageous effect: the deformation and damage of the edge portion of the plate body 100 caused by the concentration of stress applied when tightening the tightening member are minimized.

[0115] The reinforcement ribs 130 may be continuously disposed on the inner surface of the edge groove 120 along the longitudinal direction of the edge groove 120 .

[0116] According to the exemplary embodiment of the present invention, the height H and the width W of the reinforcing rib 130 increase toward the central portion between the mounting portions 110. Therefore, an advantageous effect of more effectively improving the mechanical strength of the portion where the mechanical strength is greatly reduced (the central portion between the mounting portions where the mechanical strength is low) can be obtained.

[0117] According to an exemplary embodiment of the present invention, the edge groove 120 may be provided so as not to overlap with the mounting portion 110 .

[0118] In other words, the reinforcement rib 130 may not be provided on the mounting portion 110 .

[0119] As described above, according to the exemplary embodiment of the present invention, the reinforcing rib 130 is not provided on the mounting portion 110. Therefore, the mechanical strength of a portion of the board body 100 (a portion between adjacent mounting portions 110) where the mechanical strength is relatively low can be concentratedly enhanced.

[0120] According to an exemplary embodiment of the present invention, the board body 100 may include 35 wt % or less of glass fiber.

[0121] Generally, short glass fiber reinforced composite polypropylene (PP-SGF) or long glass fiber reinforced composite polypropylene (PP-LGF) is mainly used as a reinforcing material to improve the mechanical strength of the formwork for a vehicle. In an exemplary embodiment of the present invention, long glass fiber reinforced composite polypropylene (PP-LGF) containing 70 wt% or less of glass fiber is selected and used as a reinforcing material for the plate body 100. Therefore, even if the plate body 100 is formed of recycled plastic as a main material, it can be ensured that the plate body 100 has sufficient mechanical strength.

[0122] According to an exemplary embodiment of the present invention, a panel body 100 may be stacked on an inner panel 300 made of metal to form a door template 10 for a vehicle.

[0123] Furthermore, according to the exemplary embodiment of the present invention, a structural change is implemented such that the edge groove 120 is provided at the edge portion of the plate body 100, and the reinforcing rib 130 is provided inside the edge groove 120, so that the sealing performance of the sealing member 200 can be improved. In addition, the reinforcing rib 130 is formed to include a maximum height and a maximum width at a portion (a central portion between adjacent mounting portions 110) where the mechanical strength of the plate body 100 is reduced, so that the mechanical strength of the plate body 100 can be increased. Therefore, even if recycled plastic is used as a main material, the door template 10 for a vehicle that maintains safety and reliability can be manufactured.

[0124] The door template 10 for a vehicle according to an exemplary embodiment of the present invention includes a plate body 100 made of recycled plastic. However, the mechanical strength of the door template 10 may be the same as that of a door template including a plate body made of non-recycled plastic (polypropylene (PP)).

[0125] Hereinafter, a method of manufacturing a door template for a vehicle according to an exemplary embodiment of the present invention will be described.

[0126] Figure 7 A flowchart is provided to illustrate a method of manufacturing a door template for a vehicle according to an exemplary embodiment of the present invention.

[0127] refer to Figure 7 , a method for manufacturing a door template for a vehicle according to an exemplary embodiment of the present invention includes: (a) preparing a molten resin by adding a reinforcing material to a main material containing recycled plastic; and (b) manufacturing a plate body 100 including a reinforcing rib 130 by molding the molten resin.

[0128] First, a reinforcing material is added to a main material including recycled plastic to provide a molten resin (S100).

[0132] Table 2 shows the change values ​​of the tensile strength and elongation of the plate body 100 formed by adding recycled plastic (recycled PP) to the main material (polypropylene (PP)). Referring to Table 2, it can be seen that in Manufacturing Examples 2 to 6, the tensile strength and elongation decrease as the amount of recycled PP added increases, so there is a problem with the rigidity of the plate body 100 compared to Manufacturing Example 1 without recycled plastic. Therefore, a reinforcing material can be added to solve this problem.

[0133] According to an exemplary embodiment of the present invention, the molten resin can be provided by adding 20 wt% of glass fiber as a reinforcing material to 80 wt% of a main material containing 10 wt% of recycled plastic (recycled PP) and 70 wt% of polypropylene. The molten resin can be provided by adding 33 wt% of long glass fiber reinforced composite polypropylene (e.g., PP-LGF60 (GF 60 wt%, PP 40 wt%)) containing 70 wt% or less of glass fiber as a reinforcing agent to 67 wt% of a main material containing 10 wt% of recycled plastic (recycled PP) and 57 wt% of polypropylene.

[0134] Next, the plate body 100 including the reinforcement ribs 130 is manufactured by molding the molten resin ( S200 ).

[0135] In the step S200 of manufacturing the board body 100 , the edge groove 120 and the reinforcement rib 130 may be integrated into the board body 100 .

[0136] For reference, the outer peripheral surface of the reinforcement rib 130 may include a curvature, and the height H may be determined according to Expression 1 and Expression 2 below.

[0137] [Expression 1]

[0138] 0.26D <H<0.85D

[0139] [Expression 2]

[0140] H∝L

[0141] In Expression 1 and Expression 2, H represents the height of the reinforcing rib 130 , D represents the depth of the groove 120 , and L represents the spacing distance between adjacent mounting portions 110 .

[0142] According to an exemplary embodiment of the present invention, the method of manufacturing a door template for a vehicle may further include attaching a sealing member 200 fixedly inserted into the edge groove 120 after manufacturing the panel body 100 .

[0143] For reference, the reinforcing rib 130 is integrally formed with the plate body 100 such that an outer peripheral surface thereof includes a curvature, so that the reinforcing rib 130 can effectively press the sealing member 200 without damaging the sealing member 200 .

[0144] In addition, according to the exemplary embodiment of the present invention, based on Expression 1 and Expression 2, the height of the reinforcing rib 130 is determined according to the depth of the edge groove 120, so that the mechanical strength of the plate body 100 can be enhanced. In addition, the reinforcing rib 130 of the plate body 100 coupled to the inner panel 300 can press the sealing member 200 to prevent the separation of the plate body 100 from the inner panel 300, thereby more effectively preventing (suppressing) water leakage from the door template.

[0145] According to the exemplary embodiments of the present invention described above, advantageous effects of ensuring the structural rigidity of the door template and improving the safety and reliability of the door template can be obtained.

[0146] According to the exemplary embodiment of the present invention, it is possible to obtain an advantageous effect of improving the mechanical strength of the edge portion of the door template accommodating the sealing member.

[0147] Furthermore, according to the exemplary embodiment of the present invention, an advantageous effect of improving the sealing performance can be obtained.

[0148] Furthermore, according to the exemplary embodiments of the present invention, advantageous effects of reducing costs and improving marketability can be obtained.
