[0004] [Patent Document 1] JP 2009-90725 A Summary of the Invention [Problem to be solved by the invention]
[0005] It is conceivable to modify the structure of the luggage door in Patent Document 1 to form a slanted wall extending upward and forward of the vehicle at the lower part of the luggage outer panel upper, join the tip of the slanted wall to the extension, and apply a sealer to the boundary between them. In this case, the sealer application area is invisible unless you look closely, so although the design of the vehicle is improved, it becomes difficult to apply the sealer to the desired location.
[0006] An object of the present invention is to make it possible to apply sealer to a desired sealer application area in a luggage door structure in which the sealer application area between the luggage outer panel upper and the extension cannot be confirmed without looking inside. [Means for solving the problem]
[0007] The luggage door of the vehicle of the present invention comprises a luggage outer panel upper covering the upper part of the luggage compartment at the rear of the vehicle and having a slanted wall portion formed at its lower part extending forward and upward of the vehicle, a luggage outer panel lower covering the lower part of the luggage compartment at the rear of the vehicle and having an upper end located further forward of the vehicle than the slanted wall portion of the luggage outer panel upper, and an extension having a front end connected to the upper end of the luggage outer panel lower and a rear end joined to the underside of the slanted wall portion of the luggage outer panel upper or a portion extending therefrom towards the front of the vehicle, wherein the tip of the rear end of the extension is a guide portion bent downward, and the space extending in the vehicle width direction between the guide portion of the extension and the underside of the slanted wall portion of the luggage outer panel upper is a sealant application portion.
[0008] The luggage door of the vehicle according to the present invention may further include a camera disposed below the extension and attached to the extension. Effect of the Invention
[0009] According to the present invention, the sealer can be applied from the sealer tool while the sealer tool is moved in the vehicle width direction against the guide portion of the extension, so that the sealer can be applied to the desired sealer application portion.

[0011] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The configuration described below is an example for the purpose of explanation, and can be appropriately changed according to the specifications of the vehicle, etc. The same elements in all the drawings are given the same reference numerals, and duplicated explanations will be omitted.
[0012] In the following description, unless otherwise specified, terms indicating directions and orientations such as front, rear, left, right, up, down, etc., refer to directions and orientations related to the vehicle. In each drawing, the arrow FR points forward, the arrow UP points upward, and the arrow LH points leftward.
[0013] Fig. 1 is a perspective view showing a luggage door 12 of a vehicle 10, without showing the detailed panel shape and camera 80 (see Fig. 2) shown in Figs. 2 and 3. As shown in Fig. 1, the luggage door 12 is formed into an L-shaped cross section as a whole, and covers the opening of a luggage compartment located at the rear of the vehicle body. The luggage door 12 is attached to the vehicle body so as to be rotatable about an axis above and in front of the luggage compartment, and the opening of the luggage compartment is opened and closed by the luggage door 12.
[0014] The luggage door 12 includes a luggage outer panel upper 16, a luggage outer panel lower 17, and an extension 18 (see FIG. 2). Hereinafter, the luggage outer panel upper 16 will be referred to as the outer panel upper 16, and the luggage outer panel lower 17 will be referred to as the outer panel lower 17.
[0015] The upper outer panel 16 is an exterior plate that covers the upper part of the luggage compartment and the rear part of the upper part of the luggage compartment. The upper outer panel 16 is made of aluminum, for example, and is press-formed into an L-shaped cross section. The lower outer panel 17 is an exterior plate that covers the rear part of the lower part of the luggage compartment. The lower outer panel 17 is made of aluminum, for example, and its lower edge is located above the bumper when the luggage door 12 is closed.
[0016] Tail lamps 84L, 84R are disposed at both ends in the vehicle width direction between the outer panel upper 16 and the outer panel lower 17 at the rear of the luggage door 12. A characteristic portion of this embodiment is the portion between the two tail lamps 84L, 84R.
[0017] Fig. 2 is a cross-sectional view taken along line AA in Fig. 1, showing a cross-section at approximately the center in the vehicle width direction of the rear part of the luggage door 12. Fig. 3 is a cross-sectional view taken along line BB in Fig. 1, showing a cross-section on the left side of line AA at the rear part of the luggage door 12. Note that a cross-section on the right side of line AA at the rear part of the luggage door 12 (a cross-section at a position symmetrical in the vehicle width direction with respect to line BB with respect to line AA) also has a shape similar to the cross-section shown in Fig. 3. Figs. 2 and 3 show a door structure 14 according to this embodiment.
[0018] As shown in Fig. 2, an upper end portion 40 of the outer panel lower 17 is located forward of a lower portion 20 of the outer panel upper 16. The extension 18 is provided between the lower portion 20 of the outer panel upper 16 and the upper end portion 40 of the outer panel lower 17. The extension 18 is an outer plate extending in the vehicle width direction (a direction penetrating the paper surface of Fig. 2) and is made of, for example, aluminum.
[0019] The luggage door is located approximately in the center in the vehicle width direction (the position of line AA in FIG. 1), and is equipped with a camera 80 arranged below the extension 18 as shown in FIG. 2. The camera 80 is arranged on the vehicle body to capture images of the rear of the vehicle. Images captured by the camera 80 are displayed on a display arranged inside the vehicle near the driver's seat. The camera 80 has a claw, and the camera 80 is attached to the extension 18 by inserting the claw into a hole provided in the extension 18 and fixing the claw and its periphery to the extension 18 with an adhesive.
[0020] As shown in FIGS. 2 and 3, an upper end portion 40 of the outer panel lower 17 is joined to a front end portion 50 of the extension 18 by spot welding.
[0021] The lower portion 20 of the outer panel upper 16 is formed with an inclined wall portion 21 extending forward and upward. A front portion 23 extending forward is formed at the tip of the inclined wall portion 21. The front portion 23 is disposed above the rear end portion 52 of the extension 18. The front portion 23 is provided longer on the left side (position of line BB in FIG. 1, FIG. 3) and the right side than at approximately the center in the vehicle width direction (position of line AA in FIG. 1, FIG. 2). As shown in FIG. 3, the left front portion 23 of the outer panel upper 16 is joined to the rear end portion 52 of the extension 18 by spot welding. Although not shown, the right front portion of the outer panel upper 16 is also joined to the rear end portion 52 of the extension 18 by spot welding. The front portion 23 at approximately the center in the vehicle width direction of the outer panel upper 16 may also be joined to the rear end portion 52 of the extension 18. Also, instead of the front portion 23 of the outer panel upper 16, the inclined wall portion 21 of the outer panel upper 16 may be joined to the rear end portion 52 of the extension 18 (the upper portion of the guide portion 56).
[0022] The tip of the rear end 52 of the extension 18 is bent downward to form a guide portion 56. Fig. 4 is an enlarged view of part C in Fig. 2. As shown in Fig. 4, the space extending in the vehicle width direction (the direction penetrating the paper surface of Fig. 4) between the guide portion 56 of the extension 18 and the lower surface 22 of the inclined wall portion 21 of the outer panel upper 16 forms a sealer application portion 72.
[0023] As shown in Figures 2 and 3, the sealer application section 72 is located in a position that cannot be seen unless one looks in from below. The sealer 70 is applied to the sealer application section 72 along the vehicle width direction. The sealer 70 is applied by discharging the sealer 70 from the tip of a nozzle 91 of a sealer tool 90 (see Figure 3), while bringing the tip of the nozzle 91 into contact with the guide section 56 and moving it along the vehicle width direction, as shown in Figure 4. The sealer 70 seals the gap between the outer panel upper 16 and the extension 18, preventing water from entering the inside of the vehicle from the outside through the gap.
[0024] Next, the effects of the door structure 14 of this embodiment will be described.
[0025] In the door structure 14 of this embodiment, the sealer application portion 72 between the outer panel upper 16 and the extension 18 is located in a position that cannot be seen without looking closely, but when assembling the luggage door, a worker can apply the sealer 70 from the tip of the nozzle 91 of the sealer tool 90 while placing the tip of the nozzle 91 against the guide portion 56 of the extension 18. Therefore, the sealer 70 can be applied accurately to the position of the sealer application portion 72.
[0026] Furthermore, according to the door structure 14 of this embodiment, as will be described below, it is possible to obtain advantageous effects in terms of design, extension rigidity, and luggage compartment capacity.
[0027] FIG. 5 is a cross-sectional view showing a door structure 114 according to the first comparative technique, and FIG. 6 is an enlarged view of a portion D in FIG. 5. The door structure 114 employs a step portion 158 instead of the guide portion 56 of the door structure 14 of the present embodiment. As shown in FIG. 5, the step portion 158 is formed at the rear end portion 152 of the extension 118. The front portion 123 of the outer panel upper 116 is in contact with the lower surface of the portion of the extension 118 extending rearward from the step portion 158. The boundary between the portion of the extension 118 extending rearward from the step portion 158 and the front portion 123 of the outer panel upper 116 forms a sealant application portion 172. In the door structure 114 according to the first comparative technique, as shown in FIG. 6, an operator can apply the sealant 70 from the tip of the nozzle 91 of the sealer tool 90 while applying the tip of the nozzle 91 to the step portion 158 of the extension 18.
[0028] However, in the case of the door structure 114 according to the first comparative technique, as shown in Fig. 5, the position of the part of the extension 118 to which the camera 80 is attached is lowered by the step 158, so that the amount of projection (L21) of the camera 80 from the lower end 126 of the outer panel upper 116 becomes large. In this case, there is a risk that the appearance of the rear of the vehicle will be deteriorated.
[0029] 2, the door structure 14 according to this embodiment has no step, so the position of the portion of the extension 18 to which the camera 80 is attached does not drop, and it is possible to reduce the amount of protrusion (L2) of the camera 80 from the lower end 26 of the outer panel upper 16. Therefore, the door structure 14 according to this embodiment can improve the design compared to the door structure 114 according to the first comparative technique.
[0030] In addition, in the door structure 114 (see FIG. 5) according to the first comparative technique, the step height of the step portion 158 cannot be increased in order to reduce the protrusion amount (L21) of the camera 80. On the other hand, in the door structure 14 (see FIG. 2) according to the present embodiment, the tip of the guide portion 56 is extended downward to easily increase the vertical length (height) of the guide portion 56. By increasing the vertical length of the guide portion 56, the second moment of area of the rear end portion 52 of the extension 18 can be improved, and distortion of the rear end portion 52 of the extension 18 can be suppressed. Therefore, the positional deviation of the camera 80 attached to the extension 18 can be suppressed. In addition, since the displacement of the rear end portion 52 of the extension 18 is suppressed, uneven application of the sealer 70 and breakage of the sealer 70 can be suppressed. In this way, the door structure 14 according to the present embodiment can increase the rigidity of the extension 18 compared to the door structure 114 according to the first comparative technique.
[0031] 7 is a cross-sectional view showing a door structure 214 according to the second comparative technique. In the door structure 214, compared to the door structure 114 according to the first comparative technique (see FIG. 5), the inclined wall portion 221 of the outer panel upper 216 is made longer and the rear end portion 252 of the extension 218 is moved upward (in the U direction) to reduce the amount (L22) of the camera 80 protruding from the lower end portion 226 of the outer panel upper 216.
[0032] However, in the door structure 214 according to the second comparative technique, the rear end 252 of the extension 218 moves upward (in the U direction) and also moves forward at the same time. This is because, due to limitations imposed by press molding, it is difficult to reduce the angle θ (inner angle) of the inclined wall portion 221 of the outer panel upper 216, and the rear end 252 of the extension 218 moves in a direction (FU direction) along the inclined wall portion 221 that extends at a relatively large angle θ. Therefore, in the door structure 214 according to the second comparative technique, the length L12 in the front-rear direction becomes long.
[0033] In this way, when the length L12 in the front-rear direction is long, the following two problems arise. The first problem is that the luggage space that spreads forward from the front end 250 of the extension 218 becomes narrower. The second problem is that the distance L32 from the lower end 226 of the outer panel upper 216 to the surface on which the license plate is attached (the rear side surface of the outer panel lower 17) becomes long. If the distance L32 is long, there is a possibility that the aesthetics will be poor. (A shorter distance L32 will create a neater look in terms of design.)
[0034] On the other hand, the door structure 14 according to this embodiment (see FIG. 2) does not have a longer length L1 in the front-rear direction than the door structure 214 according to the second comparative technique, and therefore the luggage space that spreads forward from the front end 50 of the extension 18 can be kept wide. In other words, the luggage capacity can be maintained. Also, the door structure 14 according to this embodiment can keep the distance L3 from the lower end 26 of the outer panel upper 16 to the surface on which the license plate is attached (the rear side surface of the outer panel lower 17) shorter than the door structure 214 according to the second comparative technique.
[0035] 8 shows the door structure 14 according to this embodiment (lower side of FIG. 8) and the door structure 214 according to the second comparative technique (upper side of FIG. 8) side by side. It can be seen from the drawing that the door structure 14 according to this embodiment is shorter in the front-rear direction by the length DF than the door structure 214 according to the second comparative technique.
[0036] Next, a modified example will be described. In the door structure 14 of the embodiment described above, as shown in FIG. 2, the upper end 40 of the outer panel lower 17 and the front end 50 of the extension 18 are joined by welding. However, the outer panel lower 17 and the extension 18 may be an integral panel. That is, it is sufficient that the upper end 40 of the outer panel lower 17 and the front end 50 of the extension 18 are joined. In this specification, "joined" refers to separate members being joined together, or being integrated without being joined.
[0037] Furthermore, in the door structure 14 of the embodiment described above, the camera 80 is attached to the extension 18, but something other than the camera 80 (for example, various sensors) may be attached to the extension 18. [Explanation of symbols]
