[0006] [Problems to be Solved by the Invention]

[0007] When the opening and closing member is operated, a load is applied via the cover member. However, the cover member is made of rubber having elasticity, and thus there is a problem that the strength and rigidity with respect to the load in the opening direction and the closing direction applied to the opening and closing member are insufficient.

[0008] An object of the present application is to provide an opening and closing member which can improve the strength and rigidity with respect to the load in the opening direction and the closing direction applied to the opening and closing member.

[0009] [Technical Means for Solving the Problems]

[0010] (1) An opening and closing member (for example, a tailgate 1 described later) which has an outer panel (for example, an outer panel 11 described later) on the outside of a vehicle body and which opens and closes a rear opening portion (for example, a rear opening portion 101 described later) of the vehicle body (for example, a vehicle body 100 described later) by operating an operation portion (for example, an operation portion 2 described later) provided at a rear end portion (for example, a rear end portion la described later), wherein a bracket member (for example, a bracket member 3 described later) is provided on the inside of the operation portion, the bracket member has a bracket member body (for example, a bracket member body 31 described later) which extends in the vehicle body front-rear direction and a vertical wall portion (for example, a rear side vertical wall portion 33 described later) which extends in the vehicle body up-down direction at an end portion (for example, a rear end portion 31b described later) of at least either one of the vehicle body front-rear direction of the bracket member body, and the vertical wall portion is fixed to the inside of the outer panel.

[0011] (2) The opening and closing member according to the above (1), wherein the bracket member can have a first rib member (e.g., the first rib member 34 described later) that connects the bracket member body and the longitudinal wall portion in an inclined manner at at least one end portion (e.g., the end portions 31c and 31d described later) in the vehicle width direction.

[0012] (3) The opening and closing member according to the above (1) or (2), wherein an inner panel (e.g., the inner panel 13 described later) can be provided inside the outer panel, the bracket member is disposed between the outer panel and the inner panel, the longitudinal wall portion has a front-side longitudinal wall portion (e.g., the front-side longitudinal wall portion 32 described later) that extends downward of the vehicle body at a front end portion of the bracket member body and a rear-side longitudinal wall portion that extends upward of the vehicle body at a rear end portion of the bracket member body, and the front-side longitudinal wall portion is fixed to the inner panel and the rear-side longitudinal wall portion is fixed to the outer panel.

[0013] (4) The opening and closing member according to the above (1) or (2), wherein the bracket member body can have a first opening portion (e.g., the first opening portion 35 described later) in which a door opening switch (e.g., the door opening switch 200 described later) that automatically opens the opening and closing member is provided.

[0014] (5) The opening and closing member according to the above (4), wherein the bracket member body can have a second opening portion (e.g., the second opening portion 36 described later) in which a camera (e.g., the camera 300 described later) is provided.

[0015] (6) The opening and closing member according to the above (5), wherein the first opening portion and the second opening portion can be disposed side by side in the vehicle width direction, and the bracket member body has a second rib member (e.g., the second rib member 37 described later) that extends in the vehicle front-rear direction between the first opening portion and the second opening portion.

[0016] [Effects of the Invention]

[0017] According to the above (1), by providing the longitudinal wall portion that extends in the vehicle up-down direction at at least the rear end portion of the bracket member in the vehicle front-rear direction, the surface of the longitudinal wall portion can receive the operation load applied to the operation portion during the opening and closing operation, and the strength and rigidity of the opening and closing member against the operation load can be improved. Since the longitudinal wall portion is fixed to the inner side of the outer panel, the strength against the load applied to the opening and closing member via the outer panel in the opening direction and the closing direction of the opening and closing member can be improved.

[0018] According to the (2), by providing the first rib member that connects the bracket member body and the longitudinal wall portion obliquely in the bracket member, it is possible to improve the strength and rigidity against the force in the twisting direction applied to the bracket member when the opening and closing member is operated and when the bracket member is attached. Therefore, it is possible to further improve the strength and rigidity of the opening and closing member.

[0019] According to the (3), the bracket member is fixed to the outer panel of the opening and closing member and the inner panel different from the outer panel, respectively, and thus it is possible to disperse the operation load applied to the bracket member when the operation portion of the opening and closing member is operated to the outer panel and the inner panel. Therefore, stress due to the operation load is not concentrated on the bracket member, and the durability of the bracket member and the operation portion is improved.

[0020] According to the (4), by providing the door open switch at the first opening portion of the bracket member body, it is possible to improve the strength and rigidity against the load applied to the door open switch when the opening and closing member is operated.

[0021] According to the (5), by providing the second opening portion for attaching the camera at the bracket member body, it is possible to reinforce the camera attachment portion with the bracket member. Other parts for reinforcing the camera attachment portion are not needed, and thus the number of parts can be reduced.

[0022] According to the (6), it is possible to suppress the decrease in the strength and rigidity due to the provision of the first opening portion and the second opening portion at the bracket member body with the second rib member. BRIEF DESCRIPTION OF DRAWINGS

[0028] Hereinafter, embodiments of the present application will be described in detail with reference to the drawings. As shown in Figure 1 , the rear portion of a vehicle body 100 has a rear opening portion 101. A tailgate 1 is attached to the rear opening portion 101 so as to be openable and closable.

[0029] Further, among the directions shown in the drawings, X1-X2 indicates the front-rear direction of the vehicle body 100. The X1 direction is the front of the vehicle body 100, and the X2 direction is the rear of the vehicle body 100. Y1-Y2 indicates the vehicle width direction of the vehicle body 100. When the vehicle body 100 is viewed from the rear, the Y1 direction is the right of the vehicle body 100, and the Y2 direction is the left of the vehicle body 100. Z1-Z2 indicates the up-down direction of the vehicle body 100. The Z1 direction is the upper side of the vehicle body 100, and the Z2 direction is the lower side of the vehicle body 100.

[0030] The tailgate 1 is an opening and closing member that opens and closes the rear opening portion 101 of the vehicle body 100. As shown in Figure 2 , the tailgate 1 has a rear end portion 1a that closes the rear end opening portion 101a of the rear opening portion 101, a pair of side portions 1b, 1b that extend from both ends in the vehicle width direction of the rear end portion 1a toward the front of the vehicle body 100, and a glass panel 1c that is installed across the rear end portion 1a and the pair of side portions 1b, 1b. The pair of side portions 1b, 1b and the glass panel 1c close the upper surface opening portion 101b of the rear opening portion 101.

[0031] As shown in Figure 2 , the tailgate 1 of the present embodiment is composed of an outer panel 11, a middle panel 12, and an inner panel 13. The outer panel 11 is a resin-made panel that constitutes the outer side surface of the tailgate 1. The middle panel 12 is a metal-made member that is disposed between the outer panel 11 and the inner panel 13 and constitutes the skeleton of the tailgate 1 together with the inner panel 13. The inner panel 13 is a resin-made panel that constitutes the inner side surface of the tailgate 1. The outer panel 11 and the middle panel 12 extend across the rear end portion 1a and the pair of side portions 1b, 1b of the tailgate 1. Since the outer panel 11 and the inner panel 13 use resin-made panels, the weight of this tailgate 1 is light. Further, Figure 2 The portion of the outer panel 11 that is disposed at the rear end portion 1a of the tailgate 1 is indicated by being broken away in the middle.

[0032] As shown in Figure 1 and Figure 3 , at the rear end portion 1a of the tailgate 1, an operation portion 2 for opening and closing operation of the tailgate 1 is provided. The operation portion 2 is formed between the outer panel 11 and the middle panel 12 by providing a step wall portion 21 that extends in the vehicle front-rear direction on the outer panel 11 that is disposed at the rear end portion 1a of the tailgate 1. As shown in Figure 3 , the step wall portion 21 faces the lower side of the vehicle body. Further, Figure 3 The illustration of the middle panel 12 is omitted in the middle.

[0033] On the inner side of the operation portion 2, a bracket member 3 composed of a metal member such as iron or aluminum is provided. In detail, the bracket member 3 is disposed between the outer panel 11 and the middle panel 12 of the operation portion 2 of the tailgate 1. As shown in Figure 4As shown, the bracket component 3 has: a bracket component body 31; and longitudinal wall portions, which are respectively disposed at the ends of the bracket component body 31 in the front-rear direction of the vehicle body and extend in the vertical direction of the vehicle body.

[0034] The bracket component body 31 has a length in the longitudinal direction of the vehicle body that is longer than the length of the stepped wall portion 21 of the operation section 2 in the longitudinal direction of the vehicle body, and is formed into a transversely elongated plate shape that is wider in the width direction of the vehicle body than its length. The bracket component body 31 spans the outer panel 11 and the middle panel 12, and is arranged with its short side along the longitudinal direction of the vehicle body.

[0035] like Figures 3 to 5 As shown, the longitudinal wall portion of this embodiment includes: a front longitudinal wall portion 32 integrally provided at the front end portion 31a of the bracket member body 31; and a rear longitudinal wall portion 33 integrally provided at the rear end portion 31b of the bracket member body 31. The front longitudinal wall portion 32 extends downward from the front end portion 31a of the bracket member body 31 with the same width as the bracket member body 31. The rear longitudinal wall portion 33 extends upward from the rear end portion 31b of the bracket member body 31 with the same width as the bracket member body 31. At both ends of the front longitudinal wall portion 32 in the vehicle width direction, protruding wall portions 321, 321 protruding forward of the vehicle body are respectively formed.

[0036] At both ends of the front longitudinal wall portion 32 in the vehicle width direction, there is a pair of protruding wall portions 321, 321 that protrude forward toward the vehicle body. The bracket component 3 is fixed to the inside of the operating part 2 by means of these pair of protruding wall portions 321, 321 and the rear longitudinal wall portion 33.

[0037] In detail, such as Figure 2 As shown, the middle panel 12 has openings 12a and 12a at positions corresponding to the protruding wall portions 321 and 321 of the bracket component 3. The protruding wall portions 321 and 321 of the front longitudinal wall portion 32 pass through the openings 12a and 12a of the middle panel 12 and abut against the inner panel 13, as shown. Figure 3 As shown, it is fixed to the surface 13a of the inner panel 13 using fixing components 322 such as adhesives and double-sided tape. Furthermore, the rear longitudinal wall portion 33 of the bracket component 3 abuts against the outer panel 11 from the inside of the operating portion 2, as shown. Figure 3 As shown, it is fixed to the inner surface 11a of the outer panel 11 using a fixing component 331 such as adhesive or double-sided tape. In addition, the surface between the protruding wall portions 321, 321 in the front longitudinal wall portion 32 can also be fixed to the middle panel 12 using double-sided tape or the like.

[0038] Thus, the bracket component 3 includes: a bracket component body 31 extending along the longitudinal direction of the vehicle body; and a front longitudinal wall portion 32 and a rear longitudinal wall portion 33, which extend in the vertical direction of the vehicle body from the front end 31a and the rear end 31b of the bracket component body 31 in the longitudinal direction of the vehicle body; and at least the rear longitudinal wall portion 33 is fixed to the inner side of the outer panel 11. The rear longitudinal wall portion 33 extends in the vertical direction of the vehicle body, thus allowing the surface of the rear longitudinal wall portion 33 to bear the operating load applied to the operating part 2 during opening and closing operations, thereby improving the strength and rigidity of the tailgate 1 against the operating load. Since at least the rear longitudinal wall portion 33 is fixed to the inner surface 11a of the outer panel 11, the strength against the load applied to the tailgate 1 via the outer panel 11 in the opening and closing directions of the tailgate 1 is improved. Furthermore, the longitudinal wall portion provided on the bracket component 3 may also be only the rear longitudinal wall portion 33.

[0039] In this embodiment, the bracket component 3 is disposed between the outer panel 11 and the inner panel 13. The front longitudinal wall portion 32 is fixed to the inner panel 13, and the rear longitudinal wall portion 33 is fixed to the outer panel 11, which is different from the inner panel 13. Therefore, the operating load applied to the bracket component 3 when operating the operating part 2 of the tailgate 1 can be distributed to the outer panel 11 and the inner panel 13, and the stress caused by the operating load will not be concentrated on the bracket component 3. As a result, the durability of the bracket component 3 and the operating part 2 is improved.

[0040] like Figure 4 As shown, the bracket component 3 has first ribs 34 and 34 at both ends 31c and 31d in the width direction of the vehicle body, which obliquely connect the bracket component body 31 and the rear longitudinal wall portion 33. The first ribs 34 and 34 are composed of the following parts: inclined surfaces 341 and 341, which extend obliquely from the upper surface 31e of the bracket component body 31 facing the upper part of the vehicle body to the front surface 33a of the rear longitudinal wall portion 33 facing the front of the vehicle body; and inner surfaces 342 and 342, which block the space between the inner sides of the inclined surfaces 341 and 341 facing each other and the upper surface 31e of the bracket component body 31 and the front surface 33a of the rear longitudinal wall portion 33.

[0041] Thus, the bracket component 3 has first ribs 34, 34 that obliquely connect the bracket component body 31 and the rear longitudinal wall portion 33, thereby improving the strength and rigidity against the torsional force applied to the bracket component 3 when operating the tailgate 1 and installing the bracket component 3. Therefore, the strength and rigidity of the tailgate 1 can be further improved. In addition, the first ribs 34 provided on the bracket component 3 may be provided only at either end 31c or 31d of the bracket component body 31. Moreover, although not shown, the first ribs may also be provided in an oblique manner connecting the bracket component body 31 and the front longitudinal wall portion 32.

[0042] likeFigure 4 As shown, the bracket component body 31 has a first opening 35. The first opening 35 is formed into a horizontally elongated rectangle representing most of the size of the bracket component body 31, and extends through the bracket component body 31. Figure 3 and Figure 5 As shown, a door opening switch 200 is installed in the first opening 35. The door opening switch 200 is a switch for automatically opening the tailgate 1. The door opening switch 200 uses a pair of upper claws 201, 201 and lower claws 202, 202 respectively provided at both ends in the width direction of the vehicle body to clamp the bracket component body 31 from the inside of the first opening 35, thereby holding it in a non-displaced manner within the first opening 35. In this way, by installing the door opening switch 200 in the first opening 35 of the bracket component body 31, the bracket component 3 of this embodiment can improve the strength and rigidity against the load applied to the door opening switch 200 when operating the tailgate 1.

[0043] Furthermore, such as Figure 4 and Figure 5 As shown, the bracket component body 31 has a second opening 36. The second opening 36 is arranged side by side with respect to the first opening 35 along the width direction of the vehicle body. The second opening 36 is smaller than the first opening 35 and extends through the bracket component body 31. A camera 300 for capturing images of the rear of the vehicle body 100 is mounted in the second opening 36. In this way, by providing the second opening 36 for mounting the camera 300 in the bracket component 3, the camera mounting part can be reinforced using the bracket component 3. No other parts are needed to reinforce the camera mounting part, thus reducing the number of parts.

[0044] The bracket component body 31 has a second rib 37 extending along the longitudinal direction of the vehicle body between the first opening 35 and the second opening 36. The second rib 37 is formed by providing a step between the first opening 35 side and the second opening 36 side of the bracket component body 31. Therefore, the second rib 37 can be used to suppress the reduction in strength and rigidity caused by the provision of the first opening 35 and the second opening 36 on the bracket component body 31. In this embodiment, the second opening 36 side is disposed below the vehicle body relative to the first opening 35 side, with the second rib 37 as the boundary; however, the first opening 35 side may also be disposed below the vehicle body relative to the second opening 36 side.
