[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-95059 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology of Patent Document 1, if the component precision and assembly precision of the door trim and the B-pillar of the vehicle body are low, there is a possibility that the door trim may fall off.

[0005] In view of the above problems, the present invention has an object to provide a vehicle side door in which the door trim is more completely prevented from falling off the inner panel. [Means for solving the problem]

[0006] In order to solve the above problems, a representative configuration of the present invention is a vehicle side door having an outer panel facing the outside of the vehicle, the vehicle side door further comprising an inner panel overlapping the inner side of the outer panel in the vehicle width direction and bending at its rear end toward the outer panel to form a rear end of the vehicle side door, a door trim arranged on the inner side of the inner panel in the vehicle width direction, an extension protruding from the rear end of the door trim and bending outward in the vehicle width direction to overlap with the rear end, and a fixing member penetrating the extension and the rear end in the fore-and-aft direction of the vehicle and fixing the extension to the rear end. Effect of the Invention

[0007] According to the present invention, it is possible to provide a vehicle side door in which the door trim is more completely prevented from falling off the inner panel. [Brief description of the drawings]

[0008] [Figure 1] 1 is a perspective view of a vehicle side door according to an embodiment of the present invention; [Diagram 2] 2 is a cross-sectional view of a portion of the vehicle side door and the seat in FIG. 1, viewed from above. [Diagram 3] 3 is a partially enlarged cross-sectional view of the vehicle side door of FIG. 2. [Figure 4] 2 is a cross-sectional view of the vehicle side door of FIG. 1 as viewed from the rear side. [Diagram 5] FIG. 2 is a rear view of the vehicle side door of FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] One embodiment of the present invention is a vehicle side door comprising an outer panel facing the outside of the vehicle, the vehicle side door further comprising an inner panel overlapping the inner side of the outer panel in the vehicle width direction and bending at its rear end toward the outer panel to form a rear end of the vehicle side door, a door trim arranged on the inner side of the inner panel in the vehicle width direction, an extension protruding from the rear end of the door trim and bending outward in the vehicle width direction to overlap with the rear end, and a fixing member penetrating the extension and the rear end in the fore-and-aft direction of the vehicle and fixing the extension to the rear end.

[0010] According to the present invention, the fixing member penetrates the extension and the rear end of the vehicle side door in the deformation direction of the outer panel and the inner panel when the vehicle side door is hit, i.e., in the vehicle front-rear direction intersecting the vehicle width direction, thereby fixing the door trim to the inner panel. Therefore, the door trim is prevented from moving in the vehicle width direction relative to the inner panel. As a result, the door trim is more thoroughly prevented from falling off the inner panel.

[0011] The vehicle side door further includes a first recess formed in the outer panel and recessed inward in the vehicle width direction for accommodating an outside handle, and a second recess formed in the door trim and recessed outward in the vehicle width direction, the first recess and the second recess being arranged so as to overlap at least partially when viewed from the vehicle width direction, and the fixing member fixes the extension portion to the rear end portion above the deepest position of the second recess.

[0012] According to the above configuration, the fixing member fixes the extension to the rear end of the side door above the deepest position of the second recess. Therefore, when the second recess of the door trim is pressed against the first recess of the outer panel, the door trim is deformed while the upper end of the door trim rotates outward in the vehicle width direction around an imaginary line extending in the vehicle front-rear direction from the penetration position of the fixing member. In this case, the upper part of the door trim moves away from the occupant. As a result, the possibility of the door trim hitting the occupant is reduced.

[0013] The vehicle side door may further include a third recess formed on the inner edge of the rear end in the vehicle width direction and recessed toward the front of the vehicle, and an extension portion is fixed to the rear end by a fixing member inside the third recess, and the third recess may have a depth sufficient to accommodate the extension portion and the fixing member.

[0014] According to the above configuration, the third recess has a depth that allows the extension and the fixing member to fit in. Therefore, the fixing member fits in the third recess. Therefore, if the fixing member protrudes toward the rear of the vehicle, it would be necessary to move the B-pillar facing the fixing member further inward, which would cause a problem of narrowing the vehicle interior space. However, this problem is suppressed. EXAMPLES

[0015] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The dimensions, materials, and other specific values ​​shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified.

[0016] FIG. 1 is a perspective view of a vehicle side door 100 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the vehicle side door 100 and a part of a seat 200 in FIG. 1, viewed from above. In FIG. 1 and all other drawings, the front of the vehicle in the vehicle longitudinal direction is indicated by an arrow F (Forward), the rear of the vehicle is indicated by an arrow B (Backward), the inside in the vehicle width direction is indicated by an arrow I (Inner), the outside in the vehicle width direction is indicated by an arrow O (Outer), the top in the vertical direction is indicated by an arrow U (Upward), and the bottom is indicated by an arrow D (Downward). In addition, the following description will be given assuming that the vehicle is an automobile. However, the present invention is not limited to this, and the vehicle may be another type of vehicle.

[0017] As shown in FIG. 1, the vehicle side door 100 is a right side door of the vehicle, and includes an outer panel 101, an inner panel 102, and a door trim 103.

[0018] The outer panel 101 shown in Fig. 1 is a panel that faces the outside of the vehicle. As shown in Fig. 2, a first recess 101a is formed in the outer panel 101. The first recess 101a is recessed toward the inside (left side) in the vehicle width direction. The first recess 101a houses an outside handle 105. The presence of the first recess 101a ensures operability of the outside handle 105.

[0019] The inner panel 102 shown in FIG. 1 is a panel that overlaps the inner side (left side) of the outer panel 101 in the vehicle width direction. As shown in FIG. 2, the inner panel 102 has a side plate portion 102a, a rear end portion 102b, and a mounting plate portion 102c. A hole 102d is formed in the side plate portion 102a. A second recess 103a of a door trim 103 described later is inserted through the hole 102d. The rear end portion 102b is bent toward the outer panel 101 on the outer side (right side) in the vehicle width direction at the rear end of the side plate portion 102a to form a rear end portion 102b of the vehicle side door 100. The rear end portion 102b faces toward the rear of the vehicle. The mounting plate portion 102c is continuous with the outer side (right side) in the vehicle width direction of the rear end portion 102b, and is attached to the back surface of the outer panel 101. The mounting plate portion 102c is attached to the rear surface of the outer panel 101 by caulking or welding.

[0020] 1 is an interior material disposed on the inner side (left side) in the vehicle width direction of the inner panel 102. The door trim 103 is provided with a second recess 103a, a door handle attachment opening 103b, and an armrest 107.

[0021] As shown in Fig. 2, the second recess 103a is recessed toward the outer side (right side) in the vehicle width direction. The depth D2 of the second recess 103a is set deeper than the depth D1 of the first recess 101a. Regarding the inclination angle of the second recess 103a with respect to the vehicle front-rear direction, the inclination angle of the rear inclined surface 103a1 on the rear side of the vehicle is formed to be steeper, and the inclination angle of the front inclined surface 103a2 on the front side of the vehicle is formed to be gentler. The second recess 103a is formed so that the occupant can easily use the armrest 107 by placing their upper arms therein.

[0022] As shown in Fig. 1, a door handle 108 is attached to the door handle attachment opening 103b. The door handle 108 is for unlocking the vehicle side door 100. The armrest 107 protrudes inward (left side) in the vehicle width direction below the second recess 103a. The armrest 107 is a portion on which an occupant rests his / her arm.

[0023] 2, a seat 200 is disposed on the inner side (left side) in the vehicle width direction of the vehicle side door 100 and the B-pillar 600. A side airbag 110 is housed in an upper portion 201 of the seat 200.

[0024] Fig. 3 is a partially enlarged cross-sectional view of the vehicle side door 100 in Fig. 2. A configuration in which the door trim 103 is fixed to the inner panel 102 by a fixing member 104 at the rear end of the vehicle side door 100 will be described in detail with reference to Fig. 3.

[0025] First, the inner panel 102 will be described. As shown in FIG. 3, the inner panel 102 has a rear end 102b. Here, the rear end 102b is the portion from point m1 to point m2 in FIG. 3. A third recess 102p is formed in this rear end 102b. The third recess 102p is recessed toward the front of the vehicle. The third recess 102p is formed with a depth H that accommodates an extension 103q and a head 104a of a fixing member 104, which will be described later. A hole 102q is formed in the bottom of the third recess 102p.

[0026] Next, the door trim 103 will be described. The door trim 103 includes an inner wall portion 103c and a step portion 103p, which are continuous with the second recess 103a. The inner wall portion 103c is a wall portion that protrudes toward the inside (left side) in the vehicle width direction. The step portion 103p is a portion that bends from the rear of the inner wall portion 103c toward the outside (right side) in the vehicle width direction and bends toward the rear of the vehicle along the inner panel 102 from the middle. The step portion 103p has an extension portion 103q on the outside (right side) in the vehicle width direction. The step portion 103p faces the B-pillar 600. The B-pillar 600 is disposed between the step portion 103p and the side airbag 110 (see FIG. 1).

[0027] The extension 103q is a portion that protrudes from the rear end of the step portion 103p of the door trim 103 and bends outward (to the right) in the vehicle width direction to overlap the rear end portion 102b. The extension 103q is fixed to the rear end portion 102b of the inner panel 102. A hole 103r is formed in the extension 103q. The extension 103q is disposed forward of the side airbag 110 in the vehicle. The extension 103q faces the B-pillar 600. Note that, in this embodiment, the extension 103q is a portion that is part of the door trim 103 and is molded from the same resin as the door trim 103, but it may be separate from the door trim 103 and molded from a resin or metal different from that of the door trim 103.

[0028] Next, the configuration of the fixing member 104 will be described. The fixing member 104 is a member that penetrates the extension 103q and the rear end 102b in the vehicle front-rear direction and fixes the extension 103q to the rear end 102b. In this embodiment, a clip is used as the fixing member 104, but other means may be used. The fixing member 104 has a head 104a and a leg 104b. In this embodiment, the leg 104b of the fixing member 104 faces almost toward the front of the vehicle. The leg 104b is passed through a hole 103r of the door trim 103 and a hole 102q of the inner panel 102. The head 104a of the fixing member 104, the extension 103q of the door trim 103, and the rear end 102b of the inner panel 102 are arranged in this order from the rear side of the vehicle.

[0029] FIG. 4 is a cross-sectional view of the vehicle side door 100 of FIG. 1 as viewed from the rear side. For convenience of explanation, FIG. 4 also shows the position of the fixing member 104. As shown in FIG. 4, the first recess 101a and the second recess 103a are arranged so that they at least partially overlap when viewed from the vehicle width direction. The fixing member 104 is arranged above the deepest position a of the second recess 103a. The fixing member 104 is arranged on the inner side (left side) of the second recess 103a in the vehicle width direction. The second recess 103a is recessed between positions y1 and y2 in the vertical direction. If the half position of the second recess 103a in the up-down direction is defined as the half position b (=(y1+y2) / 2), the fixing member 104 is arranged at the half position b in the second recess 103a. The fixing member 104 is arranged above the armrest 107.

[0030] FIG. 5 is a rear view of the vehicle side door 100 of FIG. 1. As shown in FIG. 5, the third recess 102p is formed on the inner edge of the rear end 102b in the vehicle width direction and opens toward the inner side (left side) in the vehicle width direction. Here, we return to the explanation of FIG. 3. As shown in FIG. 3, the third recess 102p is recessed toward the front of the vehicle to a depth that accommodates the extension 103q and the fixing member 104. Inside the third recess 102p, the extension 103q is fixed to the rear end 102b of the inner panel 102 by the fixing member 104. Note that the door trim 103 is fastened to the inner panel 102 by another clip (not shown) at a location other than the location of the fixing member 104 described above.

[0031] Next, a description will be given of how the vehicle side door 100 is affected when the vehicle side door 100 is hit. As shown in Fig. 3, when the outer panel 101 of the vehicle side door 100 receives a load in the direction of the arrow C, the first recess 101a of the outer panel 101 moves in a direction approaching the second recess 103a of the door trim 103. At this time, the extension 103q of the door trim 103 is penetrated by the fixing member 104 together with the rear end 102b of the inner panel 102, and therefore cannot move inward (leftward) in the vehicle width direction unless the fixing member 104 is sheared.

[0032] 4, the door trim 103 rotates such that the upper end of the door trim 103 rotates outward (to the right) in the vehicle width direction around the position of the fixing member 104. Therefore, the upper part of the door trim 103 cannot move inward (to the left) in the vehicle width direction relative to the outer panel 101. This suppresses the phenomenon in which the upper part of the door trim 103 hits the upper part of the seat 200 that accommodates the side airbag 110 and prevents the side airbag 110 from deploying.

[0033] According to the configuration of the embodiment described above, the fixing member 104 penetrates the extension portion 103q and the rear end portion 102b of the inner panel 102 in the deformation direction of the outer panel 101 and the inner panel 102 when the vehicle side door 100 is hit, that is, in the vehicle front-rear direction intersecting the vehicle width direction, thereby fixing the door trim 103 to the inner panel 102. Therefore, the door trim 103 is prevented from moving in the vehicle width direction relative to the inner panel 102. As a result, the door trim 103 is more thoroughly prevented from falling off the inner panel 102. Furthermore, the possibility that the door trim 103 hits an occupant or interferes with the deployment of the side airbag 110 installed on the side of the seat 200 is also reduced. That is, the safety of the occupants is more ensured.

[0034] In addition, the fixing member 104 fixes the extension portion 103q to the rear end portion 102b of the inner panel 102 above the deepest position a of the second recessed portion 103a. Therefore, when the second recessed portion 103a of the door trim 103 is pressed by the first recessed portion 101a of the outer panel 101, the door trim 103 is deformed while the upper end of the door trim 103 rotates outward in the vehicle width direction (to the right) about an imaginary line D (see Figs. 3 and 4) extending from the penetration position of the fixing member 104 in the vehicle front-rear direction. In this case, the upper portion of the door trim 103 moves away from the occupant. As a result, the possibility that the door trim 103 hits the occupant is reduced.

[0035] Additionally, the third recess 102p has a depth H (see FIG. 3) that accommodates the extension 103q and the fixing member 104. Therefore, the fixing member 104 fits within the third recess 102p. If the fixing member 104 protruded rearward of the vehicle, the position of the B-pillar 600 that faces the fixing member 104 would need to be moved further inward, causing a problem of narrowing the vehicle interior space, but this problem is suppressed.

[0036] The third recess 102p is recessed toward the front of the vehicle, thereby improving the rigidity. Therefore, even if the outer panel 101 collides, the extension 103q is prevented from coming off the third recess 102p. In addition, since the extension 103q and the fixing member 104 are accommodated in the third recess 102p, the surrounding vehicle body is not deformed, and a decrease in body strength caused by changing the shape of the B-pillar 600 corresponding to the operation of the vehicle side door 100 can be suppressed.

[0037] Although the preferred embodiment of the present invention has been described above with reference to the accompanying drawings, it goes without saying that the present invention is not limited to the above-described embodiment. It is clear that a person skilled in the art can think of various modifications or alterations within the scope of the claims, and it is understood that these also naturally belong to the technical scope of the present invention.

[0038] Furthermore, the present invention can be implemented by freely combining the inventions described in the claims and examples, regardless of the dependent relationships of the claims. [Industrial Applicability]
