Vehicle (vehicle)
The vehicle to which the vehicle door (hereinafter, appropriately referred to as "door 1") of the present invention is applied may be any vehicle provided with a door 1 having an inner panel 2 and an outer panel 3, and the form, type, and the like of the vehicle are not particularly limited. A door opening (not shown) for opening and closing the door 1 is formed in the vehicle body, for example.
Hereinafter, a door 1 disposed on a side portion of a rear side of a right vehicle body will be described as an example of the door 1.
Vehicle door
As shown in fig. 1, the door 1 is not particularly limited in form as long as it is a door provided with an inner panel 2 and an outer panel 3 (see fig. 5) disposed outside the vehicle of the inner panel 2. That is, the door 1 may be a side door disposed on a side surface of the vehicle body or a tail door disposed on a rear surface of the vehicle body as long as the door is opened and closed at a door opening (not shown) of the vehicle body. The door 1 may be a hinged door, a sliding door, a gull wing door, or the like. Hereinafter, as an example of the vehicle door 1, a hinged back door having a back hinge and disposed on a side portion of a right side of a vehicle body of a rear seat will be described.
The door 1 mainly includes: an inner panel 2; an outer panel 3 (see fig. 5); a skin reinforcement 4 provided on the vehicle interior side of the outer panel 3; a hinge member 5; a lower reinforcing member 6; a window glass 9; a liner not shown; and electric components such as a window device, a door lock device, and a wire harness.
< inner Panel >)
As shown in fig. 1, the inner panel 2 is a door body constituting a skeleton of the door 1. The inner panel 2 is formed of a rolled steel plate formed into a substantially quadrangular shape. The inner panel 2 has: openings 2a, 2b; a speaker setting hole 2c; an outer panel adhesive sheet 2d and a clip mounting sheet 2q (see fig. 2) protruding from the edge of the opening 2a; and a window frame portion 2s.
As shown in fig. 2, the outer peripheral edge portion of the inner panel 2 is attached to the peripheral edge portion of the outer panel 3 (see fig. 5) by hemming and welding with the skin reinforcement 4 and the lower reinforcement member 6 interposed therebetween. The inner panel 2 is connected to a center pillar (not shown) by a pair of upper and lower hinge members 5 attached to the front end portion side so as to be openable and closable. The rear end portion side of the inner panel 2 can be kept in a door closed state by a door lock device (not shown).
As shown in fig. 1, the openings 2a and 2b are work holes for performing an assembly operation for assembling built-in components such as electric components built in a hollow portion formed between the inner panel 2 and the outer panel 3, or weight-saving holes for weight reduction. A skin reinforcement 4 (see fig. 2) is provided on the vehicle outside of the openings 2a, 2b so as to overlap.
The opening 2a is, for example, a hole for performing an operation of attaching a power window device (not shown) or a wire harness. The opening 2a is formed, for example, at a position on the front side of the inner panel 2. The opening 2a has a side edge 2k extending in the up-down direction and a lower edge 2m extending in the front-back direction from the lower end of the side edge 2k (see fig. 3). An outer panel adhesive sheet 2d (cut-up portion 2 e) and a clip setting sheet 2q are formed to protrude from the lower edge 2 m.
The opening 2b is, for example, a hole for performing an operation of attaching a door lock actuator (not shown). The opening 2b is formed at a position on the rear side of the inner panel 2.
The speaker installation hole 2c is a hole to which a speaker (not shown) is attached. The speaker is mounted to the speaker mounting hole 2c with a vibration-proof sealing material (not shown), for example. A speaker arrangement hole 2c is formed in a front lower portion of the inner panel 2.
As shown in fig. 3 or 5, the outer panel adhesive sheet 2d is a protruding sheet formed to protrude from the edge of the opening 2a of the inner panel 2 toward the outer panel 3. The outer panel adhesive sheet 2d has a cut-and-raised portion 2e extending from the edge of the opening 2a toward the outer panel 3, and an adhesive surface 2f formed by bending the tip end portion of the cut-and-raised portion 2e along the outer panel 3. The outer panel adhesive sheet 2d is formed so that the width gradually becomes narrower in a range from the base end portion to the tip end portion. The outer panel adhesive sheet 2d is formed by bending an inverted L-shaped protruding sheet protruding from the flat inner panel 2 arranged to face the outer panel 3 so as to be raised in the direction of the outer panel 3.
The cut-and-raised portion 2e is a portion extending from the flat surface of the inner panel 2 to the flat surface of the outer panel 3 in the outer panel adhesive sheet 2 d. The cut-and-raised portion 2e extends from the edge of the opening 2a obliquely toward the outer panel 3. A pair of reinforcing bodies 2h extending toward an adhesion surface 2f adhering from the inner panel 2 to the outer panel 3 at the base end of the cut-and-raised portion 2e are formed in the cut-and-raised portion 2 e.
The reinforcement 2h is formed of a pair of grooves recessed at appropriate intervals along the direction in which the cut-and-raised portion 2e extends. The reinforcement body 2h is formed in a circular arc (substantially semicircular shape) in cross section. Therefore, the cut-and-raised portion 2e is reinforced by the reinforcement body 2h, and functions as a stay for maintaining the interval between the inner panel 2 and the outer panel 3.
As shown in fig. 3 or 5, the adhesive surface 2f is a surface that is adhered to the vehicle interior surface of the outer panel 3 by the adhesive a. The bonding surface 2f is formed in a substantially trapezoidal shape. An elliptical reinforcing rib 2g extending along the upper and lower bottoms of the substantially trapezoidal bonding surface 2f is formed at the center of the bonding surface 2f.
The reinforcing rib 2g is formed of a groove-like depression recessed in the bonding surface 2f. The entire periphery of the rib 2g is located in the bonding surface 2f. In other words, a (bonding) surface exists between the entire periphery of the rib 2g and the periphery of the bonding surface 2f. The reinforcing rib 2g is filled with an adhesive a (filler) for bonding the outer panel 3 and the bonding surface 2f. Therefore, the reinforcing ribs 2g function to fill the grooves of the adhesive a and to reinforce the adhesive surface 2f so as to be hard to bend. As shown in fig. 5, the reinforcing rib 2g is provided between extension lines of the pair of reinforcing bodies 2h in a side view.
The adhesive a is made of an adhesive sealing material such as a glue sealing agent (adhesive sealer) or a hot melt adhesive.
As shown in fig. 4, a portion where the boundary line L1 between the peripheral edge 2a1 of the opening 2a and the cut-up portion 2e is located is curved in a concave-convex shape matching the shape of the reinforcement 2h formed in the shape of a groove. An enlarged portion 2j that is enlarged outward (toward the opening portion 2a side) from the side edge 2e1 of the cut-and-raised portion 2e is formed in the connecting portion 2i between the cut-and-raised portion 2e and the peripheral edge 2a1 of the opening portion 2 a.
The enlarged portion 2j is a portion formed on the opening portion 2a side of the boundary line L1 and the extension line L2 of the side edge 2e1 of the cut-up portion 2 e. The enlarged portion 2j is formed at a corner portion 2n between the side edge 2e1 and the side edge 2k of the cut-and-raised portion 2e, and at a corner portion 2n between the side edge 2e1 and the lower edge 2m of the cut-and-raised portion 2 e. That is, the enlarged portions 2j are formed at both front and rear end portions of the cut-and-raised portion 2e, and the opening ends of the opening portions 2a of the enlarged portions 2j are formed in a state of drawing a smooth curve. Therefore, the enlarged portion 2j functions to make stress less concentrated on the corner portion 2n of the side edge 2e1 by being formed on the corner portion 2n of the side edge 2e1 of the cut-and-raised portion 2 e.
As shown in fig. 2, the clip installation piece 2q is, for example, a protruding piece having a hole such as the clip installation hole 2r, and the clip installation hole 2r is provided for attaching a clip (not shown) for holding a member such as a wire harness. The clip setting piece 2q is formed protruding from the edge of the opening 2 a.
As shown in fig. 1, the window frame 2s is a window frame in which the window glass 9 is disposed so as to be able to be lifted and lowered.
< outer Panel >)

The lower reinforcing member 6 is formed by press forming a steel plate.
The lower lateral reinforcement portion 61, the lower longitudinal reinforcement portion 62, and the lower front reinforcement portion 63 are formed of members that are reinforced by forming the reinforcement rib portions 61a, 62a, and 63a that are formed in the center in the width direction in cross section into a substantially hat shape that bulges toward the outer panel 3 side.

Effect of action
The vehicle door 1 according to the present embodiment is basically configured as described above, and the operational effects of the vehicle door 1 will be described next.
As shown in fig. 3, 4, or 5, a vehicle door 1 (vehicle door) of the present invention includes an inner panel 2, and an outer panel 3 disposed on the vehicle outer side of the inner panel 2, the inner panel 2 including: an opening 2a; a cut-and-raised portion 2e extending from the edge of the opening portion 2a toward the outer panel 3 side; an adhesive surface 2f formed by bending the tip of the cut-and-raised portion 2e and adhered to the outer panel 3, and a closed concave-shaped reinforcing rib 2g formed on the adhesive surface 2f.
Here, the "closed concave-shaped bead 2g" means a configuration in which the entire periphery of the bead 2g is located within the bonding surface 2f, in other words, a configuration in which a (bonding) surface is present between the entire periphery of the bead 2g and the periphery of the bonding surface 2f.
In this way, the bonding surface 2f of the cut-and-raised portion 2e is formed with the closed concave-shaped reinforcing rib 2g to enhance rigidity, and deformation of the bonding surface 2f can be suppressed. Further, the bonding surface 2f having the concave rib 2g is formed by bonding the outer panel 3 in a state where the rib 2g is closed, so that the strength can be improved. Therefore, even when a force is applied during opening and closing of the door, the adhesive surface 2f can prevent the adhesive surface 2f from bending with the rib 2g as a starting point.
As shown in fig. 5, the reinforcing rib 2g is filled with an adhesive a (filler) for bonding the outer panel 3 and the bonding surface 2f.
Thus, the adhesive a is filled in the rib 2g, and the adhesive a can be held by the concave portion of the rib 2g, so that it is possible to prevent adhesion to an undesired position (other than the rib 2 g) and concentration of stress at the position. The adhesive a can adhere to the reinforcing ribs 2g of the adhesion surface 2f, which are the portions where the rigidity is improved, and thus can more reliably prevent the deformation of the adhesion surface 2f.
As shown in fig. 5, the cut-and-raised portion 2e has a pair of reinforcing members 2h extending from the inner panel 2 toward the outer panel 3, and the bead 2g is formed between extension lines of the pair of reinforcing members 2h.
By this, the reinforcing rib 2g is formed between the extension lines of the pair of reinforcing bodies 2h, whereby both sides of the reinforcing rib 2g where the stress is concentrated can be reinforced and supported by the reinforcing bodies 2h. Therefore, the pair of reinforcement members 2h can prevent the deformation of the adhesion surface 2f and the cut-and-raised portion 2e, and can more reliably support the stress at the time of opening and closing the door by the inner panel 2.
As shown in fig. 4, a boundary L1 between the peripheral edge 2a1 of the opening 2a and the cut-up portion 2e is formed in a concave-convex shape matching the shape of the reinforcement 2h.
As a result, the portion where the boundary line L1 is located is reinforced by forming the concave-convex shape, and therefore, compared to a case where the cut-and-raised portion 2e is bent in a straight line, the cut-and-raised portion 2e can be made difficult to bend starting from the boundary line L1 due to stress at the time of opening and closing the door.
Further, an enlarged portion 2j that is enlarged outward from the side edge 2e1 of the cut-and-raised portion 2e is formed in the connecting portion 2i between the cut-and-raised portion 2e and the peripheral edge 2a1 of the opening portion 2 a.
Thereby, the enlarged portion 2j can prevent stress from concentrating on the corner portion 2n between the side edge 2e1 of the cut-and-raised portion 2e and the peripheral edge 2a1 of the opening portion 2a, and thus can suppress deformation of the cut-and-raised portion 2 e.
The opening 2a shown in fig. 4 has a side edge 2k extending in the vertical direction and a lower edge 2m extending in the front-rear direction from the lower end of the side edge 2k, a cut-and-raised portion 2e is formed at the lower edge 2m, and an enlarged portion 2j extends to a corner portion 2n between the side edge 2k and the lower edge 2 m.
Thus, the door 1 can prevent the interference of the lift glass by providing the cut-and-raised portion 2e at the lower edge 2m of the opening portion 2 a. In addition, the inner panel 2 can improve the formability of the inner panel 2 by connecting the enlarged portion 2j to the corner portion 2n between the side edge 2k and the lower edge 2m of the opening 2 a. Further, since the inner panel 2 can transmit stress at the time of opening and closing the door to the side edge 2k of the opening 2a, deformation can be prevented more reliably.
As shown in fig. 2, intermediate contact portions 42b and 43b are arranged so as to overlap each other in the thickness direction of the door of the opening portion 2a, and the intermediate contact portions 42b and 43b are formed in the skin reinforcement 4 extending in the front-rear direction from the front end portion to the rear end portion of the inner panel 2, and the intermediate contact portions 42b and 43b are bonded to the outer panel 3 by the adhesive a.
Here, the "thickness direction of the door" is the "vehicle width (left-right) direction" in the case of the side door, and the "front-rear direction" in the case of the tail door.
Thus, for example, when a load is applied to the cut-and-raised portion 2e extending from the edge of the opening 2a to the outer panel 3 or the bonding surface 2f through the outer panel 3, the load is also applied to the intermediate contact portions 42b and 43b in the vicinity of the bonding surface 2f and dispersed. Therefore, when a load in the vehicle width direction is applied to the outer panel 3, the load applied from the outer panel 3 to the adhesion surface 2f and the cut-and-raised portion 2e can be reduced.
