[0001] Cross-reference to related applications

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0092255, filed on Jul. 17, 2023, the disclosure of which is incorporated herein by reference in its entirety. Technical Field

[0003] The invention relates to a vehicle bumper and a manufacturing method thereof. Background Art

[0004] The bumper mounted on the vehicle is a component that absorbs impact in a collision event, and the bumper is provided at the front or rear of the vehicle in the longitudinal direction of the vehicle. Recent bumpers are manufactured by a long fiber injection (LFI) process, and in this case, the bumper may include a panel unit exposed to the outside of the vehicle and a reinforcement member combined with the panel unit and reinforcing the rigidity of the panel unit.

[0005] The above-mentioned bumper is formed so that one reinforcement is connected to one panel unit. Therefore, compared with the injection molding, pressing, spraying and post-processing processes for manufacturing recent bumpers, recent bumpers are subjected to vacuum forming, foaming and post-processing, so the manufacturing cost or the cost of using a mold may be reduced, but the post-processing cost is relatively high. In addition, since recent bumpers are formed so that a panel unit and a reinforcement are manufactured and then combined, there is a problem in that the difficulty of manufacturing and assembling each component increases. Therefore, in addition to connecting a plurality of panel units into one panel unit using a reinforcement, the demand for a process for increasing the rigidity of a plurality of panel units is increasing. Summary of the invention

[0006] An object of the present invention is to provide an improved vehicle bumper and a method for manufacturing the same, in which a plurality of panel units can be connected by a reinforcement member.

[0007] According to one aspect of the present invention, a vehicle bumper is provided, comprising: a panel unit, including a first panel forming a main protection area and a second panel connected to the first panel and forming an additional protection area at one side of the main protection area; and a reinforcement panel, which is arranged on non-exposed surfaces of the first panel and the second panel and fixes the first panel and the second panel to each other.

[0008] The first panel may include a first covering portion and a first connecting portion, and the second panel may include a second covering portion and a second connecting portion, wherein the reinforced panel may include: a first reinforcing portion, which is arranged on a non-exposed surface of the first covering portion; a second reinforcing portion, which is arranged on a non-exposed surface of the second covering portion; and a connecting portion, which connects the first reinforcing portion and the second reinforcing portion and surrounds the first connecting portion of the first panel and the second connecting portion of the second panel.

[0009] Non-exposed surfaces of the first and second panels may be coated with a reinforcing panel in the form of a mixture of polyurethane and long glass fibers, and then the reinforcing panel is foamed and formed in a space between the first and second panels and a mold disposed on the first and second panels.

[0010] The first panel may further include a first bent portion having a shape bent from an end of the first coupling portion and covering a region where the first coupling portion of the first panel and the second coupling portion of the second panel contact each other.

[0011] The second panel may further include a second bent portion having a shape bent from an end of the second coupling portion and covering a region where the first coupling portion of the first panel and the second coupling portion of the second panel contact each other.

[0012] The vehicle bumper may further include a blocking member disposed at ends of the first coupling portion of the first panel and the second coupling portion of the second panel and covering a gap between the ends of the first coupling portion of the first panel and the second coupling portion of the second panel.

[0013] The blocking member may be disposed between the first coupling portion of the first panel and the connecting portion of the reinforcement panel and between the second coupling portion of the second panel and the connecting portion of the reinforcement panel.

[0014] In addition, a method for manufacturing a vehicle bumper may include: placing a first panel and a second panel in a first mold; covering the first panel and the second panel with a reinforcing panel in the form of a mixture; and forming the reinforcing panel by pressing the first panel and the second panel covered with the mixture using a second mold.

[0015] Placing the first panel and the second panel in the first mold may include a process of arranging a blocking member on the first panel and the second panel located in the first mold. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Hereinafter, a vehicle bumper and a method of manufacturing the same will be described in detail with reference to the accompanying drawings, but the same reference numerals will be given to the same or corresponding components regardless of the reference numerals, and a repeated description thereof will be omitted.

[0032] Figure 1 is a rear perspective view of a vehicle bumper according to an embodiment of the present invention, Figure 2 is an exploded perspective view of a vehicle bumper according to an embodiment of the present invention, and Figure 3 It is a cross-sectional view of a vehicle bumper.

[0033] refer to Figures 1 to 3 , a vehicle bumper 1 according to an embodiment of the present invention may include a panel unit 100 and a reinforcement panel 200 .

[0034] Since the panel unit 100 is a component of the vehicle body forming the exterior of the vehicle, the panel unit 100 may be disposed at the front of the hood or at the rear of the trunk in the longitudinal direction of the vehicle (direction from the passenger compartment to the engine compartment). The panel unit 100 may include a first panel 120 and a second panel 140.

[0035] The first panel 120 may form a main protection zone that absorbs impact from a collision. The second panel 140 may form an additional protection zone on one side (lower side) of the main protection zone. The first panel 120 and the second panel 140 may be coupled to each other.

[0036] The first panel 120 may include a first covering portion 122 and a first coupling portion 124 .

[0037] The first covering portion 122 may be a main portion of the first panel 120. The first coupling portion 124 is provided on a portion of an edge region of the first covering portion 122, and the first coupling portion 124 may protrude from a non-exposed surface (hereinafter referred to as a "first non-exposed surface") of the first covering portion 122. Here, the first non-exposed surface 120a may be a surface that is not exposed to the outside of the vehicle in a state where the first panel 120 is coupled to the vehicle body. That is, in a state where the first panel 120 is coupled to the vehicle body, the first coupling portion 124 may be provided to face the inside of the vehicle from the first covering portion 122.

[0038] The second panel 140 may include a second covering portion 142 and a second coupling portion 144 .

[0039] The second covering portion 142 may be a main component of the second panel 140. The second covering portion 142 may extend from the first covering portion 122 of the first panel 120 to form a protection area. The second coupling portion 144 is disposed on a portion of an edge region of the second covering portion 142, and the second coupling portion 144 may protrude from a non-exposed surface (hereinafter referred to as "second non-exposed surface 140a") of the second covering portion 142. Here, the second non-exposed surface 140a may be a surface that is not exposed to the outside of the vehicle in a state where the second panel 140 is coupled to the vehicle body. That is, in a state where the second panel 140 is coupled to the vehicle body, the second coupling portion 144 may be disposed to face the inside of the vehicle from the second covering portion 142.

[0040] In this embodiment, the panel unit 100 includes the first panel 120 and the second panel 140, but is not limited thereto, and the panel unit 100 may be composed of two or more panels coupled to each other.

[0041] like Figure 3As shown, when the second panel 140 is coupled to the first panel 120, the second coupling portion 144 can maintain a contact state with the first coupling portion 124. At this time, the lengths of the first coupling portion 124 and the second coupling portion 144 can be the same, and the lengths of the first coupling portion 124 and the second coupling portion 144 can be 10 mm or more, but are not limited thereto. The lengths of the first coupling portion 124 and the second coupling portion 144 can be 10 mm or less. In this way, since the contact between the first coupling portion 124 and the second coupling portion 144 strengthens the connection between the first panel 120 and the second panel 140, while not exposing the connection structure to the outside, this method can be a configuration for improving the design of the panel unit 100.

[0042] The reinforcing panel 200 may be disposed on non-exposed surfaces (first non-exposed surface 120a and second non-exposed surface 140a) of the first panel 120 and the second panel 140. The reinforcing panel 200 may fix the first panel 120 and the second panel 140 to each other. The reinforcing panel 200 may include a first reinforcing portion 220, a second reinforcing portion 240, and a connecting portion 260.

[0043] The first reinforcement portion 220 may be disposed on a non-exposed surface of the first covering portion 122. The thickness of the first reinforcement portion 220 may correspond to the thickness of the first covering portion 122 of the first panel 120, but is not limited thereto. The first reinforcement portion 220 may be coupled to the first non-exposed surface 120a of the first covering portion 122 of the first panel 120 to increase the rigidity of the first panel 120. The shape of the first reinforcement portion 220 may be set to correspond to the shape of the first panel 120, but is not limited thereto.

[0044] The second reinforcing portion 240 may be disposed on the non-exposed surface of the second covering portion 142. The thickness of the second reinforcing portion 240 may correspond to the thickness of the second covering portion 142 of the second panel 140, but is not limited thereto. The second reinforcing portion 240 may be spaced apart from the first reinforcing portion using a connecting portion 260 interposed between the second reinforcing portion and the first reinforcing portion 220. The second reinforcing portion 240 may be coupled to the second non-exposed surface 140a of the second covering portion 142 of the second panel 140 to increase the rigidity of the second panel 140. The shape of the second reinforcing portion 240 may be set to correspond to the shape of the second panel 140, but is not limited thereto.

[0045] The connection part 260 may be disposed between the first reinforcement part 220 and the second reinforcement part 240. The connection part 260 may be connected to the first reinforcement part 220 and the second reinforcement part 240 to connect the first reinforcement part 220 and the second reinforcement part 240. Figure 3As shown, the thickness of the connection portion 260 may correspond to the thickness of each of the first coupling portion 124 of the first panel 120 and the second coupling portion 144 of the second panel 140 , but is not limited thereto.

[0046] The connecting portion 260 may surround the first coupling portion 124 of the first panel 120 and the second coupling portion 144 of the second panel 140. More specifically, the connecting portion 260 is connected to the first reinforcing portion 220 and the second reinforcing portion 240, and since the connecting portion 260 has a similar The connection portion 260 may be shaped like a first reinforcing portion 220 and may press the first reinforcing portion 220 toward the second reinforcing portion 240 and press the second reinforcing portion 240 toward the first reinforcing portion 220. That is, the connection portion 260 may be used as a clamp to increase the bonding force between the first panel 120 and the second panel 140.

[0047] The non-exposed surfaces of the first panel 120 and the second panel 140 may be coated with a reinforcing panel 200 in the form of a mixture of polyurethane and long glass fibers, and then the reinforcing panel 200 is foamed and formed in a space between the first panel 120, the second panel 140, and a mold disposed on the first panel 120 and the second panel 140. The thickness of the reinforcing panel 200 formed in this manner may be in the range of 2 mm to 3 mm, but is not limited thereto, and the thickness of the reinforcing panel may be varied according to the thickness of the first panel 120 and the second panel 140.

[0048] Therefore, the reinforcing panel 200 is formed to be in close contact with the first panel 120 and the second panel 140, while corresponding to the shape of the first panel 120 and the second panel 140 in the coupled state. That is, the reinforcing panel 200 can reduce the need for components (such as existing beams) for reinforcing the rigidity of the first panel 120 and the second panel 140. Therefore, the reinforcing panel 200 ensures the space between the vehicle bumper 1 and the components facing the vehicle bumper 1, and can also reduce the weight of the panel unit 100. Therefore, the vehicle weight reduction can be achieved by reinforcing the panel 200. In addition, since the reinforcing panel 200 increases the rigidity of the panel unit 100 on the non-exposed surface of the panel unit 100, the degree of freedom of vehicle design can be improved.

[0049] In the above, the reinforcement panel 200 has been exemplified as being provided on the first panel 120 and the second panel 140, but is not limited thereto, and the reinforcement panel 200 may be applied to various components constituting the exterior of the vehicle. For example, the reinforcement panel 200 may be provided on the non-exposed surface of the fender, on the non-exposed surface of the hood, on the non-exposed surface of the trunk, and on the non-exposed surface of the door. That is, the reinforcement panel 200 may be applied to any component forming the exterior of the vehicle to increase the rigidity of the component forming the exterior of the vehicle.

[0050] Hereinafter, the bent portion will be described.

[0051] Figure 4A is a view showing a first curved portion, and Figure 4B is a view showing a second bent portion.

[0052] refer to Figure 4A , the first panel 120 may further include a first bent portion 126. The first bent portion 126 may be provided on the first coupling portion 124 of the first panel 120. The first bent portion 126 may have a shape bent from an end portion of the first coupling portion 124. In this case, a bending direction of the first bent portion 126 may correspond to a direction from the first panel 120 toward the second panel 140. Therefore, when the first coupling portion 124 of the first panel 120 and the second coupling portion 144 of the second panel 140 are coupled, the first bent portion 126 is provided outside the end portion of the second coupling portion 144.

[0053] That is, the first bent portion 126 may cover the area where the first coupling portion 124 contacts the second coupling portion 144. More specifically, the first bent portion 126 may cover the gap formed between the first coupling portion 124 and the second coupling portion 144. That is, when the first panel 120 and the second panel 140 are coated with the mixture of polyurethane and long glass fibers described above, the first bent portion 126 may prevent the mixture from flowing into the gap formed by the first coupling portion 124 and the second coupling portion 144.

[0054] Therefore, the first bent portion 126 can prevent the increase of the gap between the first panel 120 and the second panel 140, and can prevent the functions of the panel unit 100 (such as impact absorption and foreign matter prevention) from being deteriorated. In addition, the first bent portion 126 can prevent the beauty of the design of the panel unit 100 from being affected due to the mixture flowing to the exposed surfaces of the first panel 120 and the second panel 140.

[0055] refer to Figure 4B , the second panel 140 may further include a second bent portion 146. The second bent portion 146 may be provided on the second coupling portion 144 of the second panel 140. The second bent portion 146 may have a shape bent from an end portion of the second coupling portion 144. In this case, a bending direction of the second bent portion 146 may correspond to a direction from the second panel 140 toward the first panel 120. Therefore, when the first coupling portion 124 of the first panel 120 and the second coupling portion 144 of the second panel 140 are coupled, the second bent portion 146 may be provided outside the end portion of the first coupling portion 124.

[0056] That is, the second bent portion 146 may cover the area where the first coupling portion 124 contacts the second coupling portion 144. More specifically, the second bent portion 146 may cover the gap formed between the first coupling portion 124 and the second coupling portion 144. Since the effect of the second bent portion is the same as that of the first bent portion 126, its description is omitted.

[0057] Hereinafter, the blocking member 300 will be described.

[0058] Figure 5 is a view showing blocking members provided on the first panel and the second panel.

[0059] refer to Figure 5 , the vehicle bumper 1 may further include a blocking member 300. The blocking member 300 may be disposed at an end of the first coupling portion 124 of the first panel 120 and an end of the second coupling portion 144 of the second panel 140. The blocking member 300 may close a gap between the first coupling portion 124 of the first panel 120 and the second coupling portion 144 of the second panel 140. The blocking member 300 may be coupled to the first panel 120 and the second panel 140 before coating the first panel 120 and the second panel 140 with a mixture of polyurethane and long glass fibers. Therefore, the blocking member 300 may prevent the coating mixture from flowing into the gap between the first coupling portion 124 and the second coupling portion 144.

[0060] like Figure 5 As shown, the barrier member 300 may be a strip of rubber material. In this case, the strip may have The truncated structure may have a shaped cross-section and may have a length along a direction in which the first coupling portion 124 and the second coupling portion 144 are provided.

[0061] That is, the strip-type blocking member 300 may be disposed between the first coupling portion 124 of the first panel 120 and the connection portion 260 of the reinforcement panel 200 and between the second coupling portion 144 of the second panel 140 and the connection portion 260 of the reinforcement panel 200. Therefore, when the reinforcement panel is formed on the non-exposed sides of the first and second panels 120 and 140, the blocking member 300 is fixed by the reinforcement panel 200, so that the holding time of the holding force of the blocking member 300 clamping the first and second panels 120 and 140 is increased, so that the coupling state between the first and second panels 120 and 140 can be firmly maintained.

[0062] The blocking member 300 may be a single-sided tape having adhesiveness. The single-sided tape type blocking member 300 may be formed in the same manner as the strip type blocking member 300. The shape surrounds the end of the first coupling portion 124 , and the adhesive surface may close the surface of the gap formed between the first coupling portion 124 and the second coupling portion 144 .

[0063] The blocking member 300 may be a staple. The staple-type blocking member 300 may pass through one of the first coupling portion 124 and the second coupling portion 144 and then pass through the other to fix the first coupling portion 124 and the second coupling portion 144 to each other. Since the staple pulls the first coupling portion 124 and the second coupling portion 144 toward each other, the gap formed between the first coupling portion 124 and the second coupling portion 144 may not be widened.

[0064] The blocking member 300 may be a clip. The clip-type blocking member 300 may have a cross-sectional shape corresponding to the strip-type blocking member 300, and the length of the clip-type blocking member may be shorter than the length of the strip-type blocking member 300. A plurality of clip-type blocking members 300 may be spaced apart from each other on the first coupling portion 124 and the second coupling portion 144 coupled to each other.

[0065] The blocking member 300 may be a double-sided tape having viscosity. The double-sided tape type blocking member 300 may be disposed on the surface where the first coupling portion 124 and the second coupling portion 144 contact each other. Therefore, when the first panel 120 and the second panel 140 are coated with a mixture of polyurethane and long glass fibers, the double-sided tape type blocking member 300 may prevent the mixture from flowing to the exposed surfaces of the first panel 120 and the second panel 140 through a gap formed between the ends of the first coupling portion 124 and the ends of the second coupling portion 144 coupled to each other.

[0066] In addition, the double-sided tape type barrier member 300 may be provided on the end surfaces of the first coupling portion 124 and the second coupling portion 144 disposed parallel to each other. Thus, the double-sided tape type barrier member 300 may close the gap formed between the ends of the first coupling portion 124 and the second coupling portion 144 coupled to each other.

[0067] In addition, the shape of the blocking member 300 may correspond to the shape of the portion where the first coupling portion 124 and the second coupling portion 144 are coupled to each other. In this case, the blocking member 300 may be made of a rigid material (e.g., plastic). That is, when the shapes of the first coupling portion 124 and the second coupling portion 144 are complex, the gap formed between the end of the first coupling portion 124 and the end of the second coupling portion 144 coupled to each other may be closed by the blocking member 300 having a shape corresponding to the shapes of the first coupling portion 124 and the second coupling portion 144.

[0068] Hereinafter, a process of manufacturing the vehicle bumper 1 will be described.

[0069] Figure 6 is a flow chart showing a method of manufacturing a vehicle bumper, and Figure 7 is a view showing a reinforcement panel provided on a first panel and a second panel.

[0070] refer to Figure 6 and Figure 7 , the method for manufacturing the vehicle bumper 1 may include: placing the first panel 120 and the second panel 140 in a first mold (S100); covering the first panel 120 and the second panel 140 with a reinforcing panel 200 in the form of a mixture (S200); and forming the reinforcing panel 200 by pressing the first panel 120 and the second panel 140 covered with the mixture with a second mold (S300). Here, the reinforcing panel 200 in the form of a mixture may be a composition mixed with polyurethane and long glass fibers.

[0071] like Figure 7 As shown, placing the first panel 120 and the second panel 140 in the first mold (S100) may include the following processes: arranging the first panel 120 in the first mold so that the exposed surface of the first panel 120 faces the first mold; and arranging the second panel 140 in the first mold so that the exposed surface of the second panel 140 faces the first mold.

[0072] Furthermore, covering the first panel 120 and the second panel 140 with the reinforcement panel 200 in the form of the mixture by spraying ( S200 ) may include covering the first non-exposed surface 120 a of the first panel 120 and the second non-exposed surface 140 a of the second panel 140 with the reinforcement panel 200 .

[0073] Furthermore, placing the first and second panels 120 and 140 in the first mold (S100) may include arranging the blocking member 300 on the first and second panels 120 and 140 in the first mold. Depending on the shapes of the first and second panels 120 and 140 or a coating process, the blocking member 300 may be omitted.

[0074] Thus, after the first panel 120 and the second panel 140 cover the mixture, when the second mold presses the first panel 120 and the second panel 140, since the mixture is foamed by the pressing force and the heat generated by the pressing force, the shape of the reinforcing panel 200 can be determined by filling the space formed by the first panel 120, the second panel 140 and the second mold with the mixture. Therefore, the vehicle bumper 1 has a structure in which the reinforcing panel 200 is provided in close contact with the first panel 120 and the second panel 140, and therefore, the reduction of weight and rigid reinforcement can be achieved at the same time through the vehicle bumper 1.

[0075] According to one embodiment, since a plurality of first panels and a second panel in a vehicle bumper are connected by a reinforcing panel, a component for connecting the plurality of panels is not required, thereby reducing manufacturing cost and manufacturing time. In addition, since the vehicle bumper has a simplified configuration consisting of a panel unit and a reinforcing panel, post-processing time can be reduced and cost can be reduced.

[0076] Furthermore, by reinforcing the panel, the vehicle bumper can have excellent rigidity and heat resistance higher than or equal to those of a conventional bumper.

[0077] Although the above description has been given with reference to the embodiments of the present invention, those skilled in the art may make various modifications and alterations to the present invention without departing from the spirit and scope of the present invention described in the appended claims. In addition, it should be understood that the differences associated with these modifications and alterations are included within the scope of the present invention defined by the appended claims.
