Description

Technical Field

[0001] The invention relates to a resin vehicle structure integrally formed of resin and used for the interior or exterior of a vehicle.

Background Art

[0002] In recent years, various resin vehicle structures integrally formed of resin have been used for some of the interior and exterior parts of vehicles. For example, in some recent vehicles, a so-called knee airbag for protecting a driver's knee during a vehicle collision is provided below the steering column, and the knee airbag is housed in a resin vehicle structure disposed below the steering column.

[0003] The resin vehicle structure housing the knee airbag is integrally formed almost entirely of black. And the knee airbag is generally housed in the resin vehicle structure with a shiny silver hook made of metal or the like locked to an attachment hole (an attachment hole provided on the upper surface facing the steering column) of the resin vehicle structure. In some vehicles, the steering column (steering) can be adjusted forward and backward and up and down so that the driver can easily operate it. When the driver moves the steering forward or upward, the end of the hook protruding from the attachment hole of the resin vehicle structure may be visible to the driver. When the end of the shiny silver hook is visible on a part of the resin vehicle structure that is entirely black, it is very conspicuous and the appearance is not good. Therefore, it is desired to shield the end of the hook from being visible to the driver.

[0004] For example, Patent Document 1 discloses a knee protection airbag device in which the end of the hook is concealed from view of the driver in an airbag cover made of synthetic resin (corresponding to a resin structure for a vehicle) that houses a knee airbag. As shown in Comparative Example 1 described later, the airbag cover has a design panel portion positioned in front of the driver's knee so as to be exposed into the vehicle interior, a connecting wall portion provided so as to extend forward from the back surface of the design panel portion, and a shielding portion provided above the connecting wall portion parallel to the connecting wall portion so as to shield the hook protruding from the mounting hole of the connecting wall portion. The rear end of the connecting wall portion and the rear end of the shielding portion are connected to the back surface of the design panel portion, and the design panel portion, the connecting wall portion and the shielding portion are integrally molded.

[0005] Furthermore, Patent Document 1 describes, as another example of the shielding portion of an airbag cover, an airbag cover in which the shielding portion is not parallel to the connecting wall portion, but extends diagonally upward and forward from a position behind the mounting hole of the connecting wall portion, as shown in [Comparative Example 2] described later. The design panel portion, the connecting wall portion, and the shielding portion are integrally molded. [Prior art documents] [Patent Documents]

[0006] [Patent Document 1] Patent No. 6806021 [Overview of the project] [Problems that the invention aims to solve]

[0007] The airbag cover described in Patent Document 1, in which the connecting wall portion and the shielding portion are parallel (the airbag retainer shown in [Comparative Example 1] described later), requires a draft angle in the direction of removing the mold when manufacturing an integrally molded resin product using a mold. As described later, this results in the thickness of the front end of the shielding portion becoming thinner than the minimum manufacturing thickness, making manufacturing difficult. If the thickness of the front end of the shielding portion is made thicker than the minimum manufacturing thickness to avoid this, the thickness of the connection portion between the shielding portion and the design panel portion becomes very thick due to the effect of the draft angle, which can cause so-called "resin sink marks" and result in multiple "indentations" on the driver's side (design surface) of the design panel portion, potentially resulting in an unsightly appearance. To avoid both of these, the mold for the shielding portion must be separated, which increases the number of molds and necessitates the additional step of removing the increased number of molds, which is undesirable.

[0008] Furthermore, in the airbag cover described in Patent Document 1, which has a shielding portion extending diagonally upward from the middle of the connecting portion (the airbag retainer shown in [Comparative Example 2] described later), as described later, the mold must be separated in order to form the shielding portion, and the direction in which the separated mold is withdrawn must be in a direction along the shielding portion. For this reason, the number of molds increases, and the process of withdrawing the increased number of molds must also be added, which is undesirable.

[0009] The present invention was conceived in view of these points, and aims to provide a vehicle resin structure that is integrally molded from resin and used for the interior or exterior of a vehicle, wherein a shielding portion that appropriately shields a part to be shielded where shielding is desired is integrally molded, and there is no need to increase the number of molds or processes when integrally molding the vehicle resin structure. [Means for solving the problem]

[0010] To solve the above problems, the first invention is a resin structure for vehicles that is integrally molded from resin and used for the interior or exterior of a vehicle. The invention comprises: a front panel positioned to be exposed inside or outside the vehicle and having a flange surface on a part of its edge that extends in the opposite direction to the exposure direction, which is the direction of exposure; a shielded panel positioned on the side of the front panel that is the opposite direction to the exposure direction, extending in the opposite direction to the exposure direction so as to be substantially parallel to the flange surface, and having a shielded portion to be shielded; a shielding panel positioned on the side of the front panel that is the opposite direction to the exposure direction, extending in the opposite direction to the exposure direction so as to be substantially parallel to the shielded panel so as to cover at least the shielded portion; and a connecting panel positioned on the side of the front panel that is the opposite direction to the exposure direction, and positioned at a predetermined distance from the back surface of the front panel which is the side of the front panel that is the opposite direction to the exposure direction, and connecting the shielded panel and the shielding panel. Furthermore, the shielding panel is connected to the back surface of the front panel, and the panel to be shielded is connected to the shielding panel by the connecting panel without being mounted on the back surface of the front panel, thus forming a resin structure for vehicles.

[0011] Next, the second invention is a resin structure for a vehicle according to the first invention, wherein the shielding panel has a first panel from the connection portion with the back surface of the front panel to the connection portion with the connecting panel, and a second panel from the connection portion with the connecting panel to the edge on the side opposite to the exposure direction. The second panel is formed to become thinner as it moves away from the front panel, and the first panel is formed to become thicker as it moves away from the front panel. [Effects of the Invention]

[0012] According to the first invention, a shielding panel, positioned substantially parallel to the shielded panel so as to cover the portion to be shielded in the shielded panel, is connected to the back surface of the front panel. Furthermore, a shielded panel having a portion to be shielded is connected to the shielding panel by a connecting panel that is located away from the back surface of the front panel and faces it, without being connected to the back surface of the front panel. With this configuration, as will be described later, the thickness of the tip of the shielding panel can be made thicker than the minimum manufacturing thickness, and the occurrence of "resin sink marks" can be avoided, allowing for the proper manufacture of a one-piece molded resin product without increasing the number of molds or processes.

[0013] According to the second invention, it is possible to more reliably avoid the occurrence of so-called "resin sink marks" on the surface of the front panel that is exposed to the interior or exterior of the vehicle, and to more reliably make the thickness of the tip of the shielding panel thicker than the minimum manufacturing thickness.

Mode for Carrying Out the Invention

[0015] Hereinafter, the resin structure for a vehicle of the present invention will be described with reference to the drawings. When the X-axis, Y-axis, and Z-axis are shown in the drawings, the X-axis, Y-axis, and Z-axis are perpendicular to each other. The X-axis direction indicates the direction in which the front panel 10 (see FIG. 1) is exposed to the interior of the vehicle (when the resin structure for the vehicle is an interior part) or the outside of the vehicle (when the resin structure for the vehicle is an exterior part), and is a substantially horizontal direction. The Y-axis direction indicates a direction perpendicular to the X-axis direction and is a substantially horizontal direction. The Z-axis direction indicates the direction upward toward the vertical. Also, the X-axis direction indicates the exposure direction of the front panel 10. However, when the V-axis is shown in the drawing, the V-axis direction indicates the direction opposite to the X-axis direction and indicates the non-exposure direction. Hereinafter, the X-axis direction will be referred to as the "exposure direction X", and the V-axis direction will be referred to as the "non-exposure direction V".

[0016] Hereinafter, as an example of the resin structure for a vehicle, an airbag retainer 1 that is disposed below the steering column in the vehicle interior and houses a knee airbag that protects the driver's knees during a vehicle collision will be described as an example.

[0017] <Appearance and overall structure of airbag retainer 1 (FIGS. 1 and 2)> As shown in FIGS. 1 and 2, the airbag retainer 1 has a front panel 10, a shielded panel 20, a shielding panel 30, a connection panel 40, a lower panel 50, etc. Also, as shown by the two-dot chain line in FIG. 2, the knee airbag 80 is housed between the shielded panel 20 and the lower panel 50, and a hook 81 made of metal or the like is locked to the mounting hole 23 of the shielded panel 20, and a hook 82 made of metal or the like is locked to the mounting hole 53 of the lower panel 50. Also, as shown in FIG. 4, the airbag retainer 1 is disposed in the vehicle interior below the steering column 90 and in front of the driver's knees.

[0018] The front panel 10 is positioned to be exposed to the interior of the vehicle, and has a flange surface 11 extending in the opposite direction V from exposure on a portion of its edge (in this case, the upper edge). A break groove 13 is formed on the back surface 12 of the front panel 10, which is the side of the front panel 10 that is opposite to the exposure direction V. When the knee airbag 80 is deployed, the break groove ruptures due to the inflation of the knee airbag, creating a window in the front panel 10, and the knee airbag pops out.

[0019] The shielded panel 20 is positioned on the side of the front panel 10 opposite to the exposure direction V, and extends from the back side of the front panel 10 toward the exposure direction V, substantially parallel to the flange surface 11. The shielded panel 20 also has a shielded portion 24 that is to be shielded. In this case, the hook 81, which is engaged with the mounting hole 23 and protrudes from the mounting hole 23, corresponds to the shielded portion 24. The shielded panel 20 is part of a one-piece molded resin product and is almost entirely black, but the hook 81 is made of a glossy silver metal or the like, which is very conspicuous to the driver and does not look good.

[0020] The shielding panel 30 is positioned on the side of the front panel 10 that is not exposed in the direction V, and extends from the back side of the front panel 10 toward the direction not exposed so as to be substantially parallel to the shielded panel 20, so as to cover at least the shielded portion 24.

[0021] The connecting panel 40 is positioned on the side of the front panel 10 that is not exposed (V) and is positioned opposite the back surface 12 of the front panel at a predetermined distance L1, connecting the panel to be shielded 20 and the shielding panel 30.

[0022] As shown in Figure 2, the exposed-direction tip 21 of the shielded panel 20, which is the tip on the side facing the exposure direction X, is connected to the connecting panel 40 without being connected to the back surface 12 of the front panel, and is connected to the shielded panel 30 via the connecting panel 40. In other words, the edge of the connecting panel 40 on the side facing the flange surface 11 is connected to the shielded panel 30 midway from the exposed-direction tip 31 toward the opposite-exposure direction V, and the edge of the connecting panel 40 on the side facing the flange surface 11 is connected to the exposed-direction tip 21 of the shielded panel 20. The exposed-direction tip 31 of the shielded panel 30, which is the tip on the side facing the exposure direction X, is connected to the back surface 12 of the front panel.

[0023] Furthermore, as shown in Figure 2, the shielding panel 30 has a first panel 30A from the connection point with the back surface 12 of the front panel to the connection point with the connecting panel 40, and a second panel 30B from the connection point with the connecting panel 40 to the edge on the side opposite to the exposure direction V (the front end 32 in the opposite direction to the exposure direction). The second panel 30B is formed to gradually become thinner as it moves away from the front panel 10, with thickness T3 > thickness T4 in Figure 2. The first panel 30A is also formed to gradually become thicker as it moves away from the front panel 10, with thickness T1 < thickness T2 in Figure 2. For example, thicknesses T1 and T4 are approximately 1.0 [mm], and thicknesses T2 and T3 are approximately 2.0 [mm].

[0024] The lower panel 50 is positioned on the side of the front panel 10 opposite to the exposure direction V, and extends from the back of the front panel 10 toward the opposite exposure direction V, substantially parallel to the shielded panel 20. The exposed end 51 of the lower panel 50, which is the end on the side of the exposure direction X, is connected to the back surface 12 of the front panel. The lower panel 50 also has mounting holes 53 into which the hooks 82 of the knee airbag 80 are secured.

[0025] <Example of a mold used for integrally molding the airbag retainer 1 (Figure 3)> Figure 3 shows examples of molds A1 to A4 used when integrally molding the airbag retainer 1 with resin, and examples of the pulping directions A2H to A4H for each mold A2 to A4. In Figure 3, gaps are intentionally shown between the airbag retainer 1 and each mold, and between adjacent molds, to make it easier to distinguish between the airbag retainer 1, which is an integrally molded resin product, and each mold A1 to A4.

[0026] After filling with molten resin in the state shown in Figure 3, and once the resin has cooled and the integral molding of the airbag retainer 1 is complete, the mold A2 is first pulled out along the pulling direction A2H. The second panel 30B of the shielding panel 30 is provided with a draft angle such that thickness T4 < thickness T3, as shown in Figure 2, so it can be easily pulled out. Note that, as shown in Figure 2, the first panel 30A has a thickness T2 > thickness T1, so the second panel 30B can have a thickness T3 of approximately 2.0 [mm] and a thickness T4 of the anti-exposure tip 32 of approximately 1.0 [mm], thereby ensuring a thickness above the minimum manufacturing thickness.

[0027] Next, mold A3 is drawn out along the drawing direction A3H. As shown in Figure 3, due to mold A3 and the drawing direction of mold A3, there is no need to provide a draft angle to the first panel 30A, so as shown in Figure 2, thickness T2 > thickness T1. Thickness T1 is, for example, about 1.0 [mm], and is a thickness that makes it difficult for so-called "resin sink marks" to occur at the connection point 10S in Figure 3 when the resin cools. If "resin sink marks" occur, multiple "indentations" are formed on the surface (design surface) on the exposed direction X side of the front panel 10, resulting in an unsightly appearance, but by setting the thickness T1 to about 1.0 [mm], the occurrence of such "resin sink marks" can be prevented. Note that there is no need to provide a draft angle to the first panel 30A, so thickness T1 to thickness T2 can be kept constant, or thickness T2 < thickness T1, but it is preferable to set thickness T2 > thickness T1 in order to ensure rigidity.

[0028] Furthermore, if the thickness T3 (see Figure 2) of the second panel 30B on the side closer to the first panel 30A is to be approximately 2.0 [mm], then it is preferable to set the thickness T2 (see Figure 2) of the first panel 30A on the side closer to the second panel 30B to be approximately 2.0 [mm]. Also, as can be seen from Figure 3, there is no need to provide a draft angle for the connecting panel 40 and the shielded panel 20, so they are set to an appropriate free thickness. A draft angle is set in the mounting hole 23 of the shielded panel 20 to pull out the mold A3.

[0029] Next, the integrally molded airbag retainer 1 can be removed by pulling out the mold A4 along the pulling direction A4H. Also, as can be seen in Figure 3, there is no need to provide a draft angle for the lower panel 50, so it is set to an appropriate free thickness. However, a draft angle is set in the mounting hole 53 of the lower panel 50 for pulling out the mold A4.

[0030] As described above, the number of molds and the direction of mold extraction when manufacturing the airbag retainer 1 as a single-piece molded resin product are the same as those for the conventional airbag retainer 801 described later. Therefore, a shielding panel can be added without increasing the number of molds or processes. Furthermore, when the airbag activates and inflates and presses against the shielded panel 20, the connecting panel 40 functions as a rib, increasing rigidity, so that the pressure of the inflated airbag is concentrated on the front panel 10. As a result, the pressure of the inflated airbag is not unnecessarily dispersed, but appropriately ruptures the rupture groove 13 of the front panel 10, and the airbag can properly protect the driver's knees.

[0031] As shown in Figure 4, the shielding panel 30 effectively prevents the driver from seeing the shielded portion 24 of the shielded panel 20 below the steering column 90.

[0032] <Appearance and overall structure of conventional airbag retainer 801 (Figures 11, 12)> Next, the appearance and overall structure of the conventional airbag retainer 801 will be described using Figures 11 and 12. The airbag retainer 801 shown in Figures 11 and 12 differs from the airbag retainer 1 shown in Figures 1 and 2 in that the shielding panel 30 and the connecting panel 40 are omitted, and the shielded panel 20 is connected to the back surface 812 of the front panel. Note that the front panel 810 is the same as the front panel 10, and the lower panel 850 is the same as the lower panel 50, so their explanation will be omitted.

[0033] The shielded panel 820 is positioned substantially parallel to the flange surface 811, and its exposed-direction tip 821, which is the edge on the exposed-direction X side, is connected to the back surface 812 of the front panel. The mounting holes 823 are the same as those of the shielded panel 20, and the shielded portion 824, to which the hook 881 of the knee airbag 880 is locked and shielding is desired, is the same as the shielded portion 24 to which shielding is desired.

[0034] Conventional airbag retainers 801 lack a panel equivalent to the shielding panel 30, so as shown in Figure 14, the shielded portion 824 may be visible to the driver, which is undesirable due to its poor appearance.

[0035] <Example of a mold used for integral molding of a conventional airbag retainer 801 (Figure 13)> Figure 13 shows examples of molds G1 to G4 for integral molding of a conventional airbag retainer 801 using resin, and examples of the pulping directions G2H to G4H for each mold G2 to G4. In Figure 13, gaps are intentionally left between the airbag retainer 801 and each mold, and between adjacent molds, to make it easier to distinguish the airbag retainer 801, which is an integrally molded resin product, from each mold G1 to G4.

[0036] As shown in Figure 13, the number of molds G1 to G4 is the same as the number of molds A1 to A4 shown in Figure 3. Also, the withdrawal directions G2H to G4H of molds G2 to G4 shown in Figure 13 are the same as the withdrawal directions A2H to A4H of molds A2 to A4 shown in Figure 3. Therefore, the airbag retainer 1 of this embodiment has a shielding portion (shielding panel 30) integrally molded to appropriately shield the shielded portion 24 where shielding is desired, and there is no need to increase the number of molds or processes when integrally molding the vehicle resin structure (airbag retainer 1).

[0037] <[Comparative Example 1] Airbag retainer 101 (Figure 5) and an example of a mold used for integral molding (Figure 6)> Next, using Figure 5, an example of the airbag retainer 101 of [Comparative Example 1] will be described in relation to the airbag retainer 1 of this embodiment shown in Figures 2 and 3. The airbag retainer 101 of [Comparative Example 1] differs from the airbag retainer 1 in that the connecting panel 40 is omitted and the shielded panel 120 is connected to the back surface 112 of the front panel, and the shielding panel 130 gradually thins from the exposed end 131 to the non-exposed end 132 due to the effect of the draft angle. A hook 181 is engaged in the mounting hole 123 of the shielded panel 120, and there is a shielded portion 124 that is to be shielded, and the shielding panel 130 shields the shielded portion 124 so that it is not visible to the driver.

[0038] Figure 6 shows examples of molds B1 to B4 and examples of the withdrawal directions B2H to B4H for each mold when integrally molding the airbag retainer 101 of [Comparative Example 1] shown in Figure 5 with resin. In Figure 6, gaps are intentionally left between the airbag retainer 101 and each mold, and between adjacent molds, to make it easier to distinguish the airbag retainer 101, which is an integrally molded resin product, from each mold B1 to B4.

[0039] The shielding panel 130 must have a draft angle to allow the mold B2 to be removed, so the thickness T5 must be greater than the thickness T6. If the thickness T5 of the shielding panel 130 at the connection point 110S shown in Figure 6 is made thicker than necessary, so-called "resin sink marks" will occur, resulting in multiple "indentations" on the surface (design surface) of the front panel 110.

[0040] If thickness T5 is set to a thickness that prevents "resin shrinkage," the thickness T6, which is reduced by the draft angle, falls below the minimum manufacturing thickness, making it difficult to achieve. If thickness T6 is made thicker than the minimum manufacturing thickness, the thickness T6, which is increased by the draft angle, becomes excessively thick, resulting in "resin shrinkage" and an undesirable appearance. To avoid both of these problems, in order to eliminate the need for a draft angle for the shielding panel 130, the mold (B5) indicated by the dotted line must be separated from mold B2, and the mold (B5) must be drawn out in the drawing direction (B5H). In this case, the number of molds increases, and the process of drawing out the increased number of molds must also be added, which is undesirable.

[0041] <[Comparative Example 2] Airbag retainer 201 (Figure 7) and an example of a mold used for integral molding (Figure 8)> Next, using Figure 7, an example of the airbag retainer 201 of [Comparative Example 2] will be described in relation to the airbag retainer 1 of this embodiment shown in Figures 2 and 3. The airbag retainer 201 of [Comparative Example 2] differs from the airbag retainer 1 in that the connecting panel 40 is omitted and the shielded panel 220 is connected to the back surface 212 of the front panel, and the shielding panel 230 is provided so as to extend diagonally upward from a position in the middle of the shielded panel 220. A hook 281 is engaged with the mounting hole 223 of the shielded panel 220, and there is a shielded portion 224 that is to be shielded, and the shielding panel 230 shields the shielded portion 224 so that it is not visible to the driver.

[0042] Figure 8 shows examples of molds C1 to C5 and examples of the pulping directions C2H to C5H for each mold when integrally molding the airbag retainer 201 of [Comparative Example 2] shown in Figure 7 with resin. In Figure 8, gaps are intentionally left between the airbag retainer 201 and each mold, and between adjacent molds, to make it easier to distinguish the airbag retainer 201, which is an integrally molded resin product, from each mold C1 to C5.

[0043] Since the shielding panel 230 is not substantially parallel to the panel to be shielded 220, it is undesirable because it is necessary to add a mold C5 and then draw out the mold C5 in the drawing direction C5H. Furthermore, since the mold C5 is drawn out in the drawing direction C5H, the extension direction of the flange surface 211 cannot be in the direction of the anti-exposure direction V, but must be in the direction of the drawing direction C5H, which is also undesirable because it restricts the extension direction of the flange surface 211.

[0044] <[Comparative Example 3] Airbag retainer 301 (Figure 9) and an example of a mold used for integral molding (Figure 10)> Next, using Figure 9, an example of the airbag retainer 301 of [Comparative Example 3] will be described in relation to the airbag retainer 1 of this embodiment shown in Figures 2 and 3. The airbag retainer 301 of [Comparative Example 3] differs from the airbag retainer 1 in that the shielded panel 320 is connected to the back surface 312 of the front panel, and the shielding panel 330 is connected to the shielded panel 320 by a connecting panel 340 without being connected to the back surface 312 of the front panel. A hook 381 is engaged in the mounting hole 323 of the shielded panel 320, and there is a shielded portion 324 that is to be shielded, and the shielding panel 330 shields the shielded portion 324 so that it is not visible to the driver.

[0045] Figure 10 shows examples of the molds D1 to D5 and the withdrawal directions D2H to D5H for each mold when integrally molding the airbag retainer 301 of [Comparative Example 3] shown in Figure 9 with resin. In Figure 10, gaps are intentionally left between the airbag retainer 301 and each mold, and between adjacent molds, to make it easier to distinguish the airbag retainer 301, which is an integrally molded resin product, from each mold D1 to D5.

[0046] Although the shielding panel 330 is approximately parallel to the shielded panel 320, the presence of a connecting panel 340 necessitates the addition of a mold D5 and a step of pulling out the mold D5 in the pulling direction D5H, which is undesirable. Furthermore, because the mold D5 is pulled out in the pulling direction D5H, the extension direction of the flange surface 311 cannot be aligned with the anti-exposure direction V, but must be aligned with the pulling direction D5H, which is undesirable as it restricts the extension direction of the flange surface 311.

[0047] The airbag retainer 1, which is a resin structure for vehicles according to the present invention, is not limited to the configuration, structure, shape, appearance, etc., described in this embodiment, and various modifications, additions, and deletions are possible without altering the essence of the present invention.

[0048] In this embodiment, the airbag retainer 1, which is placed inside the passenger compartment as part of the vehicle's interior, was described as an example of a vehicle resin structure. However, the embodiment is not limited to this, and the structure of the vehicle resin structure (airbag retainer 1) described in this embodiment can be applied to various vehicle resin structures that are integrally molded from resin and used for the interior or exterior of a vehicle.

[0049] Furthermore, in the description of this embodiment, the hook 81 of the knee airbag 80 exposed from the airbag retainer 1 was used as an example of the "part to be shielded where shielding is desired," but the "part to be shielded where shielding is desired" is not limited to the hook 81. Also, "shielding" in "part to be shielded where shielding is desired" includes not only "making it invisible to the user" but also "avoiding water exposure," etc., and refers to covering for a purpose.
