[0006] Technical Problem to be Solved by the Invention

[0007] However, in the opening / closing body for a vehicle of Patent Document 1, a long inner panel reinforcing member is provided between the main surface portion and the side surface portion in the vertical direction. That is, the long inner panel reinforcing member extends from the main surface portion in the vertical direction and is fixed to the side surface portion, and is disposed on both sides of the latch reinforcing member. As a result, in order to ensure the rigidity of the latch mounting portion, the inner panel reinforcing member is enlarged. As a result, the weight of the opening / closing body for a vehicle increases.

[0008] The technical problem of the present disclosure is to provide an opening / closing body for a vehicle that can ensure the rigidity of the latch mounting portion while achieving weight reduction of the reinforcing member.

[0009] Technical Solution for Solving the Technical Problem

[0010] The opening / closing body for a vehicle according to the present disclosure is an opening / closing body for a vehicle that is mounted on an opening of a vehicle and opens and closes the opening. The opening / closing body for a vehicle includes an outer panel, an inner panel, a hinge, a latch, and a reinforcing member. The outer panel forms an outer cover. The inner panel is disposed opposite to the outer panel. The hinge is provided at a base end portion on the rotation center side of the opening / closing body for a vehicle and connects the opening / closing body for a vehicle to the vehicle body. The reinforcing member reinforces the inner panel. The inner panel has a main surface portion, a peripheral surface portion, and a reinforcing rib portion. The main surface portion extends opposite to the outer panel. The peripheral surface portion extends from the outer peripheral edge of the main surface portion toward the outer panel and is formed with a latch mounting portion for mounting the latch. The reinforcing rib portion is formed to bulge on the main surface portion and extends from the base end portion side of the opening / closing body for a vehicle toward the latch mounting portion. The reinforcing member includes a plate-shaped first reinforcing member and a long-strip-shaped second reinforcing member. The plate-shaped first reinforcing member is joined so as to overlap with the latch mounting portion. The long-strip-shaped second reinforcing member is disposed in a diagonal bracing shape between the main surface portion and the latch mounting portion.

[0011] According to this opening / closing body for a vehicle, the rigidity of the main surface portion of the inner panel is improved by the reinforcing rib portion. The long-strip-shaped second reinforcing member is fixed to the reinforcing rib portion and the first reinforcing member and is disposed in a diagonal bracing shape between the main surface portion and the latch mounting portion. Thereby, an opening / closing body for a vehicle can be provided that can ensure the rigidity of the latch mounting portion while achieving weight reduction of the reinforcing member.

[0012] Alternatively, the second reinforcing member may extend along the extending direction of the reinforcing rib portion.

[0013] According to this structure, since the second reinforcing member extends along the reinforcing rib portion and extends to the latch mounting portion, the latch mounting portion is supported in a straight line shape by the reinforcing rib portion and the second reinforcing member. Thereby, the rigidity of the latch mounting portion can be ensured while reducing the weight of the reinforcing member.

[0014] Alternatively, the second reinforcing member may be formed such that the width in the thickness direction of the opening / closing body for a vehicle increases toward the first reinforcing member.

[0015] According to this structure, since the second reinforcing member increases toward the first reinforcing member, the second reinforcing member easily functions as a diagonal brace between the latch mounting portion and the main surface portion. Thereby, it is easy to ensure the rigidity of the latch mounting portion.

[0016] Alternatively, the vehicle opening / closing body may be a tailgate that uses the upper end portion of the vehicle opening / closing body as a base end portion and the lower end portion of the vehicle opening / closing body as a swing end portion, and opens and closes the opening at the rear of the vehicle body up and down. Alternatively, the latch mounting portion may be formed at the center in the vehicle width direction of the peripheral surface portion on the swing end portion side of the vehicle opening / closing body. Alternatively, a pair of reinforcing rib portions may be provided sandwiching the latch mounting portion in the vehicle width direction. Alternatively, a pair of second reinforcing members may be provided sandwiching the latch mounting portion in the vehicle width direction, and the reinforcing rib portions and the first reinforcing member may be connected to the left and right sides in the vehicle width direction of the latch, respectively.

[0017] According to this structure, the load applied to the latch mounting portion can be transmitted to a pair of reinforcing rib portions and reinforcing members arranged in the vehicle width direction. Thereby, it is easy to ensure the rigidity of the latch mounting portion.

[0018] Alternatively, the pair of reinforcing rib portions may be respectively inclined and extended downward and toward the center in the vehicle width direction from the vicinity of the side end portions on both sides in the vehicle width direction of the main surface portion toward the latch mounting portion.

[0019] According to this structure, the surface rigidity of the main surface portion can be effectively improved by the pair of reinforcing rib portions, and the load input via the latch can be released to the side end portion side where the transmission efficiency to the main surface portion is relatively high.

[0020] Alternatively, the upper portion of the main surface portion may be a window frame portion that forms a glass opening for mounting a rear window. Alternatively, third reinforcing members may be provided along the glass opening at the lower portions of the window frame portions on the left and right sides in the vehicle width direction of the glass opening. Alternatively, the reinforcing rib portions may be extended from the position overlapping with the third reinforcing members toward the latch mounting portion.

[0021] According to this structure, since the reinforcing rib portions are extended in a manner of connecting the third reinforcing members and the latch mounting portion, the load input via the latch can be released to the third reinforcing members that strengthen the lower portion of the window frame. Thereby, the load input via the latch can be released more effectively and reliably.

[0022] Alternatively, the reinforcing rib portion may have a pair of side surfaces erected from the main surface portion in a cross-sectional view cutting the long side direction and a top surface connecting between the pair of side surfaces. The second reinforcing member may have a first extended surface portion extending along the main surface portion in a cross-sectional view and a second extended surface portion extending in the thickness direction of the vehicle opening / closing body. Alternatively, at the other end of the second reinforcing member, the first extended surface portion is joined to the top surface, and the second extended surface portion is joined to the side surface, so that the other end of the second reinforcing member is fixed to the reinforcing rib portion.

[0023] According to this structure, the load input via the latch is reliably transmitted to the reinforcing rib. Thereby, both the second reinforcing member and the reinforcing rib portion bear the load input via the latch. As a result, it is easy to make the reinforcing member lightweight.

[0031] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. It should be noted that, in the following description, the front-rear direction of the vehicle in the drawings is denoted as Q, and the front is denoted as F. In addition, the vehicle width direction in the drawings is denoted as P, and the right side as viewed from the rear of the vehicle is denoted as R. Further, the up-down direction of the vehicle in the drawings is denoted as G, and the upper side is denoted as U.

[0032] As Figure 1 and Figure 2 shown, the vehicle opening / closing body 1 of the present disclosure is installed in an opening of a vehicle (for example, a rear opening C) and opens and closes the opening. The vehicle opening / closing body 1 includes an inner panel 2, an outer panel 4 (see Figure 2 ), a latch 8, a latch reinforcement member (an example of a first reinforcing member) 8b, a hinge 10, a second reinforcing member 14, a left side reinforcement member (an example of a third reinforcing member) 16a, and a right side reinforcement member (an example of a third reinforcing member) 16b.

[0033] The latch reinforcement member 8b, the second reinforcing member 14, the left side reinforcement member 16a, and the right side reinforcement member 16b are members for reinforcing the inner panel 2. It should be noted that, Figure 1This is a view of the state in which the outer panel 4 constituting the exterior cover of the vehicle is removed. In the present embodiment, the vehicle opening / closing body 1 is a tailgate that is vertically swingably mounted on the rear opening C of the vehicle via a hinge 10. In the vehicle opening / closing body 1, the inner panel 2 and the outer panel 4 are arranged to face each other, and the edge portions of the inner panel 2 and the outer panel 4 are joined to form a hollow shape. Therefore, the thickness direction of the tailgate coincides with the front-rear direction Q of the vehicle.

[0034] The inner panel 2 has a main surface portion 6, a peripheral surface portion 7, and a reinforcing rib portion 12. The main surface portion 6, the latch mounting portion 8a, the hinge mounting portion 10a, and the reinforcing rib portion 12 of the inner panel 2 are formed by stamping a metal plate. The outer panel 4 may be a known outer panel that is arranged to face the inner panel 2, and the description thereof is omitted.

[0035] The main surface portion 6 faces the outer panel 4 in the front-rear direction Q and extends in the vertical direction G. The main surface portion 6 has a substantially rectangular shape, and an outer peripheral edge 9 is formed around the main surface portion 6.

[0036] The peripheral surface portion 7 extends from the outer peripheral edge 9 toward the outer panel 4 in the front-rear direction Q. A latch mounting portion 8a for mounting a latch 8 is formed on the peripheral surface portion 7. The peripheral surface portion 7 includes a lower end portion (an example of a swing end portion) 7a, an upper end portion (an example of a base end portion) 7b, a left end portion (an example of a side end portion) 7c, and a right end portion (an example of a side end portion) 7d. The left end portion 7c is located on the left side in the vehicle width direction P. The right end portion 7d is located on the right side in the vehicle width direction P.

[0037] Below the upper end portion 7b at the upper part of the main surface portion 6, a window frame portion 6a for forming a glass opening for mounting a rear window is provided. At the lower parts of the window frame portions 6a on the left and right sides in the vehicle width direction P of the glass opening of the main surface portion 6, a pair of left and right side portion reinforcing members 16a and 16b for strengthening the main surface portion 6 are provided. The left side portion reinforcing member 16a and the right side portion reinforcing member 16b are formed by joining a plate-shaped metal plate from the upper part of the main surface portion 6. The left side portion reinforcing member 16a extends from the left end portion 7c toward the central portion 6c in the vehicle width direction P of the main surface portion 6. The right side portion reinforcing member 16b extends from the right end portion 7d toward the central portion 6c in the vehicle width direction P of the main surface portion 6.

[0038] The latch mounting portion 8a is formed at the lower end portion 7a of the peripheral surface portion 7. A latch 8 that engages with a striker C1 provided at the periphery of the rear opening C of the vehicle is mounted on the latch mounting portion 8a. As Figure 3 shown, a latch opening 8d through which the latch 8 is inserted is provided in the latch mounting portion 8a. The latch mounting portion 8a is subjected to loads due to the vibration of the vehicle and the opening and closing of the vehicle opening / closing body 1. Therefore, in the present embodiment, a latch reinforcing member 8b for strengthening the periphery of the latch opening 8d is provided in the latch mounting portion 8a.

[0039] AsFigure 1 As shown, the latch mounting portion 8a is provided at the center portion 6c in the vehicle width direction P of the circumferential surface portion 7. In the present embodiment, as Figure 2 shown, a circumferential surface bottom surface 7f extending from the lower end edge 9a of the main surface portion 6 toward the outer panel 4 is formed. At the center portion 6c in the vehicle width direction P of the circumferential surface bottom surface 7f, the latch mounting portion 8a is formed by joining a latch reinforcing member 8b. More specifically, the latch reinforcing member 8b is formed by matching the shape of a metal plate-like member with the circumferential surface bottom surface 7f. The latch reinforcing member 8b is overlapped and joined with the upper surface of the center portion 6c in the vehicle width direction P of the circumferential surface bottom surface 7f, thereby strengthening the periphery of the latch opening 8d of the circumferential surface bottom surface 7f. This strengthened portion becomes the latch mounting portion 8a.

[0040] As Figure 1 shown, the hinge 10 is mounted on a hinge mounting portion 10a formed at the upper end portion 7b of the vehicle opening / closing body 1, connects the vehicle opening / closing body 1 to the vehicle body, and pivotally supports the vehicle opening / closing body 1 on the rear opening C. A pair of hinge mounting portions 10a are provided at intervals in the vehicle width direction P with the center portion 6c interposed therebetween. In the present embodiment, the upper end portion 7b on which the hinge 10 is mounted becomes the base end portion on the rotation center side of the vehicle opening / closing body 1, and the lower end portion 7a disposed on the opposite side in the vertical direction G with respect to the upper end portion 7b across the main surface portion 6 functions as a swing end portion of the swing. Thereby, the vehicle opening / closing body 1 swings up and down to open and close the rear opening C of the vehicle.

[0041] The reinforcing rib portion 12 is formed to bulge on the main surface portion 6 and extends from the upper end portion 6b side of the vehicle opening / closing body 1 toward the latch mounting portion 8a. In the present embodiment, the reinforcing rib portion 12 is formed to be recessed on the main surface portion 6 in a direction away from the outer panel 4. The reinforcing rib portion 12 has a left reinforcing rib portion 12a and a right reinforcing rib portion 12b that are disposed at intervals in the vehicle width direction P with the center portion 6c interposed therebetween. The reinforcing rib portion 12 is formed, for example, by stamping to bulge and be recessed on the main surface portion 6 in a direction away from the outer panel 4. As Figure 3 shown, the left reinforcing rib portion 12a and the right reinforcing rib portion 12b each have a top surface 12c that extends obliquely along the main surface portion 6 and a pair of side surfaces 12d that extend from the top surface 12c to the main surface portion 6. More specifically, the pair of side surfaces 12d are erected from the main surface portion 6 in a cross-sectional view taken in the longitudinal direction of the reinforcing rib portion 12 (see Figure 5 ). The top surface 12c connects between the pair of side surfaces 12d.

[0042] As Figure 1As shown, the rib portion 12 extends from a position different from the lower end portion 7a of the peripheral surface portion 7 toward the latch mounting portion 8a. In the present embodiment, the rib portion 12 is disposed between the lower end portion 7a and the upper end portion 7b, and extends from the side end portion located on the vehicle width direction P side of the main surface portion 6 toward the central portion 6c. More specifically, a pair of rib portions 12 extend obliquely downward and toward the center of the vehicle width direction P from near the left end portion 7c and the right end portion 7d of the peripheral surface portion 7 on both sides in the vehicle width direction P of the main surface portion 6 toward the latch mounting portion 8a. That is, the left rib portion 12a formed on the left side portion of the main surface portion 6 extends from the left side portion reinforcing member 16a toward the central portion 6c, and extends obliquely downward toward the latch mounting portion 8a. The right rib portion 12b formed on the right side portion of the main surface portion 6 extends from the right side portion reinforcing member 16b toward the central portion 6c, and extends obliquely downward toward the latch mounting portion 8a. The left rib portion 12a and the right rib portion 12b are formed in a bilaterally symmetric shape with the central portion 6c interposed therebetween. As Figure 1 and Figure 3 shown, the left rib portion 12a extends to a position overlapping with the left side portion reinforcing member 16a in the front-rear direction Q, and is joined to the left side portion reinforcing member 16a. Similarly, the right rib portion 12b extends to a position overlapping with the right side portion reinforcing member 16b in the front-rear direction Q, and is joined to the right side portion reinforcing member 16b.

[0043] As Figure 1 shown, a pair of second reinforcing members 14 are provided sandwiching the latch mounting portion 8a in the vehicle width direction P. The pair of second reinforcing members 14 connect the rib portion 12 and the latch reinforcing member 8b on the left and right sides in the vehicle width direction P of the latch 8, respectively. More specifically, the second reinforcing member 14 extends from the rib portion 12 along the extending direction of the rib portion 12 to the latch mounting portion 8a, and is fixed to the rib portion 12 and the latch mounting portion 8a. Accordingly, the second reinforcing member 14 is disposed in a diagonal bracing shape between the rib portion 12 and the latch mounting portion 8a.

[0044] The second reinforcing member 14 is in a long strip shape, and has a left second reinforcing member 14a and a right second reinforcing member 14b disposed at intervals in the vehicle width direction P with the central portion 6c interposed therebetween. In the present embodiment, as Figure 3As shown, the second reinforcing member 14 extends linearly along the extending direction of the rib portion 12. The left second reinforcing member 14a and the right second reinforcing member 14b are fixed to the fixing surface 8c of the latch reinforcing member 8b by joining or fastening at the end portions on the side of the latch reinforcing member 8b (in this embodiment, the lower end, an example of one end), and this fixing surface 8c is joined to the latch mounting portion 8a. More specifically, the left second reinforcing member 14a and the right second reinforcing member 14b extend downward from the rib portion 12 toward the latch mounting portion 8a, respectively. In addition, the left second reinforcing member 14a and the right second reinforcing member 14b extend obliquely along the inclination of the rib portion 12 toward the center portion 6c in the vehicle width direction P. The end portions of the left second reinforcing member 14a and the right second reinforcing member 14b on the side of the rib portion 12 (in this embodiment, the upper end, an example of the other end) are fixed to the linear left rib portion 12a and right rib portion 12b by joining or fastening.

[0045] Figure 4 The second reinforcing member 14 shown is the left second reinforcing member 14a. It should be noted that in this embodiment, since the right second reinforcing member 14b has a left - right symmetric shape with the left second reinforcing member 14a, the description thereof is omitted. As Figure 4 shown, the left second reinforcing member 14a has a first extending and disposing surface 14c, a second extending and disposing surface 14d, a mounting surface 14e, and an anti - rotation member 14f. The first extending and disposing surface 14c extends along the main surface portion 6. The second extending and disposing surface 14d extends in the thickness direction of the outer panel 4 toward the vehicle opening / closing body 1. The mounting surface 14e extends along the latch reinforcing member 8b. The mounting surface 14e is fixed to the fixing surface 8c by joining or fastening, and this fixing surface 8c is recess - formed in the latch reinforcing member 8b. The anti - rotation member 14f extends in the vehicle width direction P from the first extending and disposing surface 14c and contacts the main surface portion 6, thereby preventing the left second reinforcing member 14a from rotating in the up - down direction G.

[0046] The first extending and disposing surface 14c extends along the top surface 12c of the rib portion 12. Figure 5 is a cross - sectional view taken in the longitudinal direction of the left rib portion 12a and the left second reinforcing member 14a, cutting the end portion of the left second reinforcing member 14a on the side of the rib portion 12. Figure 5 shows the fixing state of the left rib portion 12a and the left second reinforcing member 14a. As Figure 5 shown, the first extending and disposing surface 14c of the left second reinforcing member 14a is fixed by joining or fastening to the top surface 12c of the rib portion 12 at the end portion of the left second reinforcing member 14a on the side of the rib portion 12.

[0047] As Figure 4 and Figure 5As shown, the second extended installation surface 14d extends along the side surface 12d of the reinforcing rib portion 12, forming an L-shaped configuration with the first extended installation surface 14c. The second extended installation surface 14d of the left second reinforcing member 14a is joined to the side surface 12d of the reinforcing rib portion 12 at the end portion of the left second reinforcing member 14a on the side of the reinforcing rib portion 12. The second reinforcing member 14 is formed such that the width in the thickness direction of the vehicle opening / closing body 1 (the front-rear direction Q in the present embodiment) increases as it approaches the latch reinforcement 8b. In the present embodiment, the area of the second extended installation surface 14d increases as it approaches the latch reinforcement 8b. That is, the second extended installation surface 14d has a substantially triangular shape in which the length in the direction extending toward the outer panel 4 increases as it approaches the lower side. The substantially triangular base of the second extended installation surface 14d is connected to the installation surface 14e. In this way, the second extended installation surface 14d functions as a brace between the first extended installation surface 14c and the installation surface 14e by being connected to the first extended installation surface 14c and the installation surface 14e. In addition, since the left second reinforcing member 14a is fixed to the main surface portion 6 and the latch mounting portion 8a, the left second reinforcing member 14a functions as a brace for the main surface portion 6 and the latch mounting portion 8a.

[0048] In this way, by forming the second reinforcing member 14 and the reinforcing rib portion 12 in a straight line and connecting the latch mounting portion 8a, the left side portion reinforcement 16a, and the right side portion reinforcement 16b in a straight line, the latch mounting portion 8a is pressed by both the reinforcing rib portion 12 and the second reinforcing member 14. As a result, the surface rigidity of the main surface portion 6 can be effectively improved by the pair of reinforcing rib portions 12. In addition, the load input via the latch 8 has a higher rigidity in the main surface portion 6 than in other portions and is released toward the side end portion where the load is transmitted more effectively. As a result, compared with the case where the second reinforcing member 14 is disposed on both sides in the vehicle width direction P with the latch mounting portion 8a interposed therebetween as in the tailgate of Patent Document 1, the second reinforcing member 14 can be reduced. Therefore, the second reinforcing member 14 can be made lightweight while ensuring rigidity. In addition, by configuring the vehicle opening / closing body 1 in this way, the load applied to the latch mounting portion 8a can be borne by both the reinforcing rib portion 12 and the second reinforcing member 14 and transmitted to the left side portion reinforcement 16a and the right side portion reinforcement 16b. As a result, the load input via the latch 8 can be released to the side end portion more effectively and reliably. In addition, since the second reinforcing member 14 functions as a brace, it is easy to ensure the rigidity of the latch mounting portion 8a. As a result, all the reinforcing members for reinforcing the inner panel 2 including the latch reinforcement 8b, the second reinforcing member 14, the left side portion reinforcement 16a, and the right side portion reinforcement 16b can be easily made lightweight.

[0049] As described above, according to the present disclosure, a vehicle opening / closing body 1 can be provided that can ensure the rigidity of the latch mounting portion 8a while achieving lightweight.
