[0006] [Problems to be solved by the invention]

[0007] However, the placement of the annular reinforcement member in a location where strength and rigidity are not required increases the weight and cost of the opening and closing member. Furthermore, the mounting of the annular reinforcement member on the inner side of the vehicle body requires consideration of positioning and dimensional errors, resulting in poor productivity.

[0008] An object of the present invention is to provide an opening and closing member capable of reducing weight and cost while ensuring the strength and rigidity required for the opening and closing member.

[0009] [Methods of solving the problem]

[0010] (1) The opening and closing component of the present invention is the following opening and closing component (for example, the tailgate 1 described later), which is composed of an outer panel arranged on the outer side of the vehicle body (for example, the outer panel 11 described later) and a reinforcing component arranged on the inner side of the vehicle body of the aforementioned outer panel to form a window frame (for example, the window frame 10 described later) spanning all four sides, and is installed to a rear opening portion (for example, the rear opening portion 101 described later) of a vehicle body (for example, the vehicle body 100 described later) via a pair of hinges (for example, the hinge 102 described later) so as to be openable and closable, wherein: the aforementioned reinforcing component has a closed cross-section portion (for example, the closed cross-section portion 23 described later), and the closed cross-section portion is formed by the outer reinforcing component arranged on the outer side of the vehicle body (for example, the outer panel 11 described later The side reinforcement member 21) and the inner reinforcement member arranged on the inner side of the vehicle body (for example, the inner reinforcement member 22 described later) are formed; the aforementioned closed cross-section portion has, on both sides in the width direction of the vehicle body: a pair of front and rear closed cross-section portions (for example, the front and rear closed cross-section portions 231 described later), which extend in the front and rear directions of the vehicle body; and, a pair of inclined closed cross-section portions (for example, the inclined closed cross-section portion 232 described later), which extend obliquely from the end portions on the front side of the vehicle body of the aforementioned pair of front and rear closed cross-section portions (for example, the end portions 231a described later) toward the inner side in the width direction of the vehicle body; and, an open cross-section portion (for example, the open cross-section portion 24 described later) is respectively provided between the aforementioned pair of hinges and the aforementioned pair of front and rear closed cross-section portions.

[0011] (2) In the opening and closing member described in (1), the open cross-section portion may be arranged to span between the inner end portions (for example, the inner end portions 232a described later) of the pair of inclined closed cross-section portions in the vehicle body width direction.

[0012] (3) In the opening and closing parts described in (1) or (2) above, the pair of inclined closed cross-section portions may extend from the ends of the pair of front and rear closed cross-section portions on the front side of the vehicle body until they approach a portion where the window frame extends linearly along the width direction of the vehicle body on the front side of the vehicle body (for example, the front end portion 10c).

[0013] (4) In the opening and closing parts described in (1) or (2) above, a middle panel (for example, the middle panel 12 described later) may be provided on the inner side of the vehicle body at the rear side of the vehicle body of the aforementioned outer panel, and a portion of the aforementioned middle panel (for example, the end portion 12a described later) may be provided at a corner portion (for example, the corner portion 10e) at the rear side of the vehicle body of the aforementioned window frame.

[0014] (5) In the opening and closing parts described in (1) or (2) above, a buffer part (for example, the buffer part 3 described later) may be provided on the outer side of the width direction of the vehicle body of the pair of front and rear closed cross-section parts corresponding to the corner parts of the window frame on the rear side of the vehicle body, so as to abut against the side of the vehicle body when the rear opening part is closed.

[0015] (6) In the opening and closing member described in (1) or (2), the pair of hinges may be mounted on an end portion of the inner reinforcing member on the front side of the vehicle body (for example, an end portion 22a described later).

[0016] [Effects of the Invention]

[0017] According to the above (1), in addition to ensuring strength and rigidity by attaching a pair of hinges to the vehicle body, the opening and closing member can also ensure strength and rigidity by utilizing the closed cross-section formed by the front and rear closed cross-sections and the inclined closed cross-section. Therefore, while ensuring the required strength and rigidity of the opening and closing member, the increase in weight and cost of the opening and closing member can be suppressed by providing the open cross-section.

[0018] According to the above (2), the open cross-section portion is arranged across the inner end portions of a pair of inclined closed cross-section portions in the vehicle body width direction, thereby ensuring the strength and rigidity required for the opening and closing components while utilizing the open cross-section portion to ensure wiring space for components such as harnesses inside the opening and closing components.

[0019] According to the above (3), the strength and rigidity of the corner portion of the window frame on the vehicle body front side, to which stress is easily applied during opening and closing, can be ensured.

[0020] According to the above (4), the strength and rigidity of the corner portion of the window frame on the vehicle body rear side, to which stress is easily applied during opening and closing, can be ensured.

[0021] According to the above (5), by providing a buffer member in the front and rear closed cross-section portions having high strength and rigidity, the strength and rigidity of the corner portion of the window frame on the vehicle body rear side, to which stress is easily applied during opening and closing, can be further ensured.

[0022] According to the above (6), the hinge can be reinforced by attaching the hinge to the inner reinforcing member having high strength and rigidity. Therefore, the opening and closing member can be opened and closed smoothly, and the durability of the mechanism for opening and closing is also improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 As shown, a rear opening 101 is provided at the rear of a vehicle body 100. A tailgate 1 is attached to the rear opening 101 via a pair of hinges 102, 102 so as to be openable and closable.

[0031] In the directions shown in the figure, X1-X2 denote the front-to-back direction of the vehicle body. The X1 direction corresponds to the front of the vehicle body 100, and the X2 direction corresponds to the rear of the vehicle body 100. Y1-Y2 denote the width direction of the vehicle body. When viewing the vehicle body 100 from the rear, the Y1 direction corresponds to the right direction of the vehicle body 100, and the Y2 direction corresponds to the left direction of the vehicle body 100. Z1-Z2 denote the vertical direction of the vehicle body. The Z1 direction corresponds to the upper direction of the vehicle body 100, and the Z2 direction corresponds to the lower direction of the vehicle body 100.

[0032] The tailgate 1 is an opening and closing member for opening and closing the rear opening 101 of the vehicle body 100. Figure 1 and Figure 2 As shown, the tailgate 1 includes a rear end portion 10a that closes the rear end opening 101a of the rear opening 101; a pair of side portions 10b, 10b that extend from both ends of the rear end portion 10a in the vehicle body width direction toward the front of the vehicle body 100; and a front end portion 10c that connects the vehicle body front end portions of the pair of side portions 10b, 10b. The upper portion of the rear end portion 10a, the pair of side portions 10b, 10b, and the front end portion 10c form a window frame 10 that spans the entire perimeter of the tailgate 1. A glass panel G is mounted within the window frame 10.

[0033] like Figures 1 to 3As shown, the tailgate 1 of this embodiment is composed of an outer panel 11, a middle panel 12, and an inner panel 13. The outer panel 11 is a resin panel that constitutes the outer surface of the tailgate 1. The middle panel 12 is a metal component arranged between the outer panel 11 and the inner panel 13, and together with the inner panel 13, constitutes the skeleton of the tailgate 1. The inner panel 13 is a resin panel that constitutes the inner surface of the tailgate 1. The outer panel 11 and the inner panel 13 extend across the rear end 10a, the two side portions 10b, 10b, and the front end 10c of the tailgate 1, and constitute the outer side surface of the vehicle body of the window frame 10. The middle panel 12 is arranged at the rear end 10a of the tailgate 1. Since the outer panel 11 and the inner panel 13 are made of resin panels, the tailgate 1 is lightweight and low-cost.

[0034] The tailgate 1 includes reinforcement members 2, 2 disposed on the vehicle body inner side of an outer panel 11. Specifically, the reinforcement members 2, 2 are disposed between the outer panel 11 and the inner panel 13, respectively, along the window frames 10 of the tailgate 1, which are disposed on both sides in the vehicle body width direction. Because the reinforcement members 2, 2 are substantially symmetrical in the vehicle body width direction, the following description will focus on the structure of one reinforcement member 2.

[0035] The reinforcement member 2 is composed of an outer reinforcement member 21 disposed on the outside of the vehicle body and an inner reinforcement member 22 disposed on the inside of the vehicle body. Both the outer reinforcement member 21 and the inner reinforcement member 22 are formed by forming a metal sheet. Regarding the outer and inner sides of the vehicle body, when the tailgate 1 is in the closed position with the rear opening 101, the side farther from the inside of the vehicle body 100 is referred to as the outer side of the vehicle body, and the side closer to the inside of the vehicle body 100 is referred to as the inner side of the vehicle body.

[0036] The outer reinforcement members 21 are respectively arranged at the side portions 10b, 10b of the tailgate 1 corresponding to the two side portions of the window frame 10 in the vehicle body width direction. Figure 2 and Figure 3 As shown, the outer reinforcement member 21 extends in the vehicle front-rear direction along the side portion 10b extending in the vehicle front-rear direction, and is bent into a U-shape at the end portion on the front side of the vehicle body toward the inner side in the vehicle width direction so as to reach the front end portion 10c of the tailgate 1.

[0037] The inner reinforcement member 22 is respectively arranged at the side portions 10b, 10b of the tailgate 1 corresponding to both sides of the window frame 10 in the vehicle body width direction, and overlaps with the outer reinforcement member 21 and is fixed to the outer reinforcement member 21 by welding or the like. Figure 2 and Figure 3As shown, the inner reinforcement member 22, like the outer reinforcement member 21, extends in the vehicle front-rear direction along the side portion 10b extending in the vehicle front-rear direction. At its end on the vehicle front side, it curves into a U-shape toward the inside in the vehicle width direction so as to reach the front end portion 10c of the tailgate 1. On the vehicle front side, the inner reinforcement member 22 is arranged so as to protrude further toward the vehicle front side and inward in the vehicle width direction than the outer reinforcement member 21.

[0038] like Figure 4 As shown, the reinforcement member 2 has a closed cross-section portion 23 formed by the overlap of the outer reinforcement member 21 and the inner reinforcement member 22. The closed cross-section portion 23 forms a closed space, with the outer reinforcement member 21 blocking the upper side of the vehicle body and the inner reinforcement member 22 blocking the lower side of the vehicle body. The outer reinforcement member 21 and the inner reinforcement member 22 extend along the side portion 10b in the vehicle body front-to-back direction and curve inward in the vehicle body width direction at their ends on the front side of the vehicle body. Therefore, the closed cross-section portion 23 also extends along the side portion 10b in the vehicle body front-to-back direction and curves inward in the vehicle body width direction at their ends on the front side of the vehicle body.

[0039] Specifically, the closed cross-section portion 23 includes, on the side portion 10b, a front-rear closed cross-section portion 231 extending in the vehicle body front-rear direction, and an inclined closed cross-section portion 232 extending obliquely inward in the vehicle body width direction from the vehicle body front-side end 231a of the front-rear closed cross-section portion 231. Specifically, the closed cross-section portion 23 is arranged so as to extend from the side portion 10b of the window frame 10 through the vehicle body front-side corner portion 10d of the window frame 10 to the end portion 10c of the front end portion.

[0040] Because the outer reinforcement member 21 is smaller (shorter) than the inner reinforcement member 22, an open cross-section portion 24, which does not include a closed cross-section, is formed between the hinge 102 and the inclined closed cross-section portion 232, closer to the vehicle body front. The open cross-section portion 24 is a portion of the window frame 10 where neither the outer reinforcement member 21 nor the inner reinforcement member 22 exists, or where only the inner reinforcement member 22 exists. In the tailgate 1 of this embodiment, the portion of the inner reinforcement member 22 on the vehicle body front side curves slightly inward in the vehicle body width direction from the corner 10d of the window frame 10 and is interrupted at this curve. Therefore, the open cross-section portion 24 is also located between the vehicle body width direction inner ends 232a, 232a of the pair of inclined closed cross-section portions 232, 232 in the front end portion 10c of the window frame 10.

[0041] The reinforcement member 2 having the closed cross-section portion 23 forms a hollow frame in the window frame 10 of the tailgate 1. Therefore, the strength and rigidity of the side portions 10b, 10b and the corner portions 10d, 10d of the window frame 10 of the tailgate 1 are improved. In particular, the front and rear closed cross-section portions 231 have the following effect: the latching mechanism, i.e., the striker 103 (see FIG. 1 ), which is applied to the hinge 102 and the vehicle body 100 provided at the rear end portion 10a when the tailgate 1 is opened and closed. Figure 1 and Figure 3 ) to strengthen the tailgate 1. The inclined closed cross-section portion 232 strengthens the tailgate 1 by counteracting the stress concentration on the corner 10d when the tailgate 1 is opened and closed. Furthermore, in addition to the hollow shape of the reinforcement member 2, the presence of the open cross-section portion 24 between the hinge 102 and the inclined closed cross-section portion 232 ensures the required strength and rigidity of the tailgate 1 while suppressing increases in weight and cost. Since the tailgate 1 is attached to the vehicle body 100 using a pair of hinges 102, 102, the strength and rigidity of the front side of the vehicle body are ensured, eliminating the concern of insufficient strength and rigidity due to the presence of the open cross-section portion 24.

[0042] The open cross-section portion 24 of this embodiment has a portion arranged across the inner end portions 232a, 232a of a pair of inclined closed cross-section portions 232, 232 in the vehicle body width direction. Therefore, while ensuring the strength and rigidity required for the tailgate 1, the open cross-section portion 24 can be used to ensure a wiring space S for components such as wiring harnesses (not shown) inside the window frame 10 of the tailgate 1.

[0043] The inclined closed cross-section portion 232 extends from the front-vehicle-side end 231a of the front-rear closed cross-section portion 231 to near the front end 10c, which is the portion of the window frame 10 extending linearly along the vehicle width on the front side of the vehicle. In other words, the inclined closed cross-section portion 232 is arranged via the corner 10d of the window frame 10 on the front side of the vehicle. This corner 10d is a portion where stress is easily applied when the tailgate 1 is opened and closed, and where strength and rigidity are required. By arranging the inclined closed cross-section portion 232 via the corner 10d of the window frame 10, the strength and rigidity of the corner 10d of the window frame 10, which is easily applied during opening and closing, can be ensured.

[0044] like Figure 2 As shown, a portion of the center panel 12 of the tailgate 1, namely, the two end portions 12a, 12a in the vehicle body width direction, are positioned at the corners 10e, 10e of the window frame 10 on the vehicle body rear side. Since the center panel 12 is made of metal, the corners 10e, 10e are reinforced by the center panel 12. This ensures the strength and rigidity of the corners 10e, 10e of the window frame 10, where stress is most likely to be applied when the tailgate 1 is opened and closed.

[0045] like Figure 6 As shown, a buffer member 3 is provided on the outer side 231b of the vehicle body width direction of the front and rear closed cross-section portion 231 of the tailgate 1 corresponding to the corner portion 10e of the window frame 10 on the vehicle body rear side. The buffer member 3 is formed into a substantially rectangular block made of rubber or the like. The buffer member 3 is provided on both sides of the tailgate 1 in the vehicle body width direction. Figure 7 As shown, the vehicle body 100 is provided with a contact member 104 at a location corresponding to the buffer member 3. The contact member 104 is made of synthetic fiber or the like, and when the tailgate 1 closes the rear opening 101, it contacts the buffer member 3, thereby receiving the load of the tailgate 1 via the buffer member 3. The buffer member 3 mitigates the impact of contact with the contact member 104 on the vehicle body 100.

[0046] The buffer members 3 are located in areas of the window frame 10 of the tailgate 1 where stress is most likely to be applied during opening and closing. Since the buffer members 3 are located in the front and rear closed cross-section portions 231 of the reinforcing member 2, which are highly strong and rigid, the strength and rigidity of the corners 10e, 10e of the window frame 10 on the rear side of the vehicle body, where stress is most likely to be applied during opening and closing, can be further ensured.

[0047] like Figure 5 As shown, a pair of hinges 102, 102, which secure the tailgate 1 to the vehicle body 100, are attached to the vehicle body front-side ends 22a, 22a of the inner reinforcement members 22, 22 of the reinforcement members 2, 2, respectively. Because the metal inner reinforcement members 22, 22 are high in strength and rigidity, attaching the hinges 102, 102 to the inner reinforcement members 22, 22 reinforces the hinges 102, 102. This allows for smooth opening and closing of the tailgate 1, and improves the durability of the opening and closing mechanism.
