Description

Technical Field

[0001] This specification discloses a rear structure of a vehicle. Background Art

[0002] The rear windshield washer is a device for spraying washing liquid onto the rear tailgate glass of the vehicle. A washing hose is connected to the rear windshield washer, and washing liquid is supplied to the rear windshield washer via the washing hose.

[0003] Conventionally, the washer hose has been arranged along the rear pillar, which is a pillar located at the boundary between the back and the side of the vehicle. Conventionally, the rear hose extends from the washer hose to the rear pillar, extends along the rear pillar toward the lower side of the vehicle, and then further extends toward the front of the vehicle.

[0004] However, in a vehicle, a charging unit is sometimes arranged near the rear wheel. For example, in the case of an electric vehicle (hereinafter referred to as "BEV") and a plug-in hybrid electric vehicle (hereinafter referred to as "PHEV"), a charging unit is mounted to receive power from the outside. The charging unit is arranged between the rear end column and the middle column located on the front side compared to the rear end column. On the other hand, a charging unit is not mounted in a gasoline engine vehicle and a hybrid electric vehicle (hereinafter referred to as "HEV"). Summary of the invention

[0005] Here, as described above, the conventional washer hose extends downward along the rear end column and then extends toward the front of the vehicle. In such a case, when a charging unit is mounted on the vehicle, in order to prevent the washer hose from interfering with the charging unit, its path needs to be changed. As a result, the path of the washer hose will be different depending on whether the charging unit is present, and even the type of washer hose used in the layout will be different depending on whether the charging unit is present. As a result, the number of parts that need to be managed at the manufacturing site will increase, making it complicated.

[0006] Therefore, it is considered to arrange the washer hose along the middle pillar instead of the rear pillar. However, there are components such as the trim plate clamp used to install the trim plate on the vehicle body and the curtain airbag around the middle pillar. Therefore, if the washer hose is arranged only along the middle pillar, there is a possibility that the washer hose will interfere with the trim plate clamp or other components or the washer hose will be blocked.

[0007] In addition, Japanese Patent Application Laid-Open No. 2004-123064 discloses that a drain hose is passed through a C-pillar. However, Japanese Patent Application Laid-Open No. 2004-123064 does not make any study on preventing interference with components as described above.

[0008] Therefore, in this specification, a vehicle rear structure capable of more appropriately arranging a washer hose is disclosed.

[0009] The vehicle rear structure disclosed in the present specification is characterized in that it comprises: a rear end pillar, which is located at the boundary between the side and rear sides of the vehicle; an intermediate pillar, which is located on the front side compared to the rear end pillar with the corner window glass in between; a washer hose, which guides the washer fluid to the rear windshield washer, and after extending from the rear windshield washer to the upper part of the intermediate pillar, bends toward the lower side of the vehicle and extends toward the lower side of the vehicle along the intermediate pillar; one or more hose clamps, which are connected to the intermediate pillar and hold the washer hose, and the one or more hose clamps respectively include: a coupling portion, which is connected to the intermediate pillar; a connecting portion, which extends from the coupling portion toward the rear side of the vehicle; and a holding portion, which holds the washer hose at the end of the connecting portion, and the washer hose is divided into an upstream hose and a downstream hose before and after the bending portion, and the upstream hose and the downstream hose are connected by a substantially L-shaped joint.

[0010] By providing a joint at the curved portion of the washer hose, the washer hose around the curved portion is effectively prevented from swinging. Furthermore, interference between the washer hose and other components and even blockage of the washer hose and the occurrence of abnormal sounds can be effectively prevented. In addition, since the retaining portion of the hose clamp is located closer to the rear side of the vehicle than the coupling portion, interference between the washer hose and the decorative panel clamp can be effectively prevented even if the hose clamp is coupled to the vicinity of the decorative panel clamp. Furthermore, blockage of the washer hose can be effectively prevented. As a result, according to the above-mentioned structure, the washer hose can be arranged more appropriately.

[0011] In this case, the structure may be as follows, namely, one or more decorative panel clamps are installed on the intermediate column, the one or more hose clamps include a first hose clamp and a second hose clamp located at the lower side of the vehicle compared to the first hose clamp, and a straight line connecting a retaining portion of the first hose clamp and a retaining portion of the second hose clamp is offset toward the rear side of the vehicle compared to the one or more decorative panel clamps.

[0012] By adopting such a structure, interference between the washer hose and the trim panel clamp and clogging of the washer hose can be effectively prevented.

[0013] In this case, the structure may be as follows: the one or more decorative panel clamps include a first decorative panel clamp and a second decorative panel clamp located on the lower side of the vehicle compared to the first decorative panel clamp; the first hose clamp is arranged at a position closer to the first decorative panel clamp than the second hose clamp, and the second hose clamp is arranged at a position closer to the second decorative panel clamp than the first hose clamp.

[0014] By setting such a structure, the washer hose is constrained near the decorative panel clamp, thereby preventing the washer hose from swinging near the decorative panel clamp, and as a result, interference between the washer hose and the decorative panel clamp and even blockage of the washer hose can be effectively prevented.

[0015] Furthermore, the following structure may be adopted, namely, the rear end of the connection portion of the first hose clamp is bent toward the first trim panel clamp, and the rear end of the connection portion of the second hose clamp is bent toward the second trim panel clamp.

[0016] By setting such a structure, the washer hose is restrained closer to the decorative panel clamp. Therefore, the washer hose can be prevented from swinging near the decorative panel clamp. As a result, interference between the washer hose and the decorative panel clamp and even blockage of the washer hose can be effectively prevented.

[0017] In addition, the structure may be configured as follows, that is, a curtain airbag is also provided, the curtain airbag passes through the upper portion of the middle pillar and extends in the front-rear direction of the vehicle, the upper corner of the corner window glass is an acute angle, the washer hose is arranged on the lower side of the vehicle with respect to the curtain airbag, and the washer hose is bent at an acute angle or approximately 90 degrees in a manner along the upper corner of the corner window glass.

[0018] By adopting such a structure, it is possible to more effectively prevent the washer hose from interfering with other components (for example, a curtain airbag, etc.).

[0019] According to the vehicle rear structure disclosed in this specification, the washer hose can be arranged more appropriately. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Features, advantages, and technical and industrial significance of exemplary embodiments of the present invention will be described below with reference to the accompanying drawings, in which like symbols represent like elements, and in which:

[0021] Figure 1 A schematic diagram of the rear of the vehicle.

[0022] Figure 2 This is a view of the C-pillar and its surroundings as viewed from the cabin side.

[0023] Figure 3 It is a schematic diagram of the rear part of the vehicle of the comparative example. DETAILED DESCRIPTION

[0024] Hereinafter, the vehicle rear structure will be described with reference to the drawings. Figure 1 is a side view of the rear of the vehicle. Figure 2 1 is a diagram of the vicinity of the C-pillar 22 viewed from the side of the vehicle compartment. In each of the figures, Fr, Up, and Out respectively represent the front, the top, and the outer side in the vehicle width direction of the vehicle 10. In addition, a resin panel called a decorative panel is usually installed on the inner side of the vehicle 10, but in Figure 2 The decorative panel is omitted in the illustration.

[0025] like Figure 1 As shown, the vehicle 10 has a C-pillar 22 and a D-pillar 20. The D-pillar 20 is a frame member extending in the vertical direction of the vehicle at the boundary between the back and the side of the vehicle 10. The D-pillar 20 is equivalent to a "rear end pillar". The C-pillar 22 is a pillar located on the front side of the vehicle with the corner window glass 16 in between compared to the D-pillar 20. The C-pillar 22 is equivalent to a "middle pillar". The rear door 14 is arranged on the front side of the C-pillar 22. Therefore, it can also be said that the C-pillar 22 is sandwiched by the corner window glass 16 and the rear door 14.

[0026] A curtain airbag 52 is installed near the ceiling in the vehicle. The curtain airbag 52 is an airbag that deploys like a curtain covering the side window glass 15 to protect the occupant when an impact occurs. Before use, the curtain airbag 52 is folded into a substantially rod shape and installed at the boundary line between the side of the vehicle and the ceiling, that is, the ceiling line.

[0027] A rear fender panel 30 is disposed below the C-pillar 22 and the D-pillar 20. A wheel arch is formed at a lower portion of the rear fender panel 30, and a rear tire 32 is disposed in the wheel arch.

[0028] In the case of a vehicle 10 that requires external charging, such as a BEV or a PHEV, a charging unit 36 ​​is disposed on the vehicle width direction inner side of the rear fender 30. On the other hand, in the case of a vehicle 10 that does not require external charging, such as a gasoline engine vehicle or an HEV that cannot be externally charged, the charging unit 36 ​​is not mounted on the vehicle 10.

[0029] A rear door glass 12 is disposed at the back of the vehicle 10. A rear windshield washer 40 is disposed above the rear door glass 12 to spray washing liquid toward the rear door glass 12. Figure 1 The rear windshield washer 40 is illustrated as being away from the rear side of the vehicle 10, but the actual rear windshield washer 40 is installed on the rear side of the vehicle 10. Figure 1 In the figure, for ease of viewing, the rear windshield washer 40 is shown in a larger scale than in reality relative to the vehicle 10 .

[0030] The rear windshield washer 40 is connected to the washer hose 42. Figure 1 Although the washer hose 42 is illustrated by a thick solid line in FIG. 8 , the actual washer hose 42 is arranged in a gap space between the vehicle body and the trim panel, that is, in a place that cannot be visually confirmed from the outside.

[0031] The washer hose 42 connects a washer liquid tank (not shown) disposed at the front portion of the vehicle to the rear windshield washer 40 . The washer liquid is supplied to the rear windshield washer 40 through the washer hose 42 .

[0032] according to Figure 1 It can be clearly understood that in this example, the washer hose 42 bends toward the lower side of the vehicle after extending from the rear windshield washer 40 to the upper portion of the C-pillar 22, and extends toward the lower side of the vehicle along the C-pillar 22. Furthermore, the washer hose 42 bends toward the front of the vehicle after extending from the C-pillar 22 to the vicinity of the lower end of the rear fender 30, and extends toward the front of the vehicle along the door sill 28.

[0033] The reason why the washer hose 42 is arranged along the C-pillar 22 in this manner will be described in comparison with the technology of the comparative example. Figure 3 FIG. 1 is a schematic diagram of the rear portion of a vehicle 10* of a comparative example. Figure 3 As shown in FIG. 1 , in the vehicle 10 * of the comparative example, the washer hose 42 * extends downward not along the C-pillar 22 but along the D-pillar 20 . Also, the washer hose 42 reaching the rear fender 30 extends toward the front of the vehicle.

[0034] Here, as described above, in the case of a vehicle that needs external charging, a charging unit 36 ​​is disposed on the side of the rear fender 30. In this case, the washer hose 42* avoids the path of the charging unit 36 ​​so as not to interfere with the charging unit 36. Figure 3 The layout is carried out along the path shown by the thick solid line.

[0035] On the other hand, in the case of the vehicle 10 that does not require external charging, there is no charging unit 36 ​​around the rear fender 30. In this case, the washer hose 42* is arranged in a path such that the path length is shortened. Specifically, the washer hose 42 is arranged in a path such that it crosses the rear fender 30 diagonally, that is, Figure 3 The arrangement is carried out along the path shown by the dotted line.

[0036] That is, in the structure of the comparative example, the arrangement path of the washer hose 42* differs depending on whether the charging unit 36 ​​is present. As a result, the type of the washer hose 42* and the type of the mounting component used differ depending on whether the charging unit 36 ​​is present. In this case, a variety of washer hoses 42* and mounting components need to be prepared at the manufacturing site of the vehicle 10*, which increases the burden of component management at the manufacturing site.

[0037] On the other hand, in this case, as mentioned above, and if Figure 1 As shown, the washer hose 42 is arranged at the C-pillar 22 instead of the D-pillar 20. In this case, the path of the washer hose 42 does not change depending on the presence or absence of the charging unit 36. Therefore, the same type of washer hose 42 and mounting parts can be used regardless of the presence or absence of the charging unit 36. As a result, according to this example, the burden of parts management at the manufacturing site can be reduced.

[0038] However, around the C-pillar 22, there are a trim panel clamp 50 for mounting the trim panel on the vehicle body, a curtain airbag 52, etc. If the washer hose 42 interferes with these components, it may be blocked and the washer fluid may not flow properly. Therefore, in this example, a dedicated hose clamp and a joint are used to mount the washer hose 42 on the vehicle body around the C-pillar 22. Figure 2 to explain.

[0039] like Figure 2 As shown in FIG. 1 , the C-pillar 22 is sandwiched between the corner window glass 16 and the door opening 17. In addition, the upper end of the C-pillar 22 is connected to the ceiling line 26 that constitutes the boundary between the side and ceiling of the vehicle 10. Figure 2 In FIG. 1 , the dark-ink hatching shows the vehicle body including the C-pillar 22. In addition, the dark-ink hatching area shows the flange portion for joining the inner panel and the outer panel constituting the vehicle body.

[0040] The curtain airbag 52 is installed on the inner surface of the vehicle body along the ceiling line 26. In addition, the C-pillar 22 is provided with decorative plate clamps 50f and 50s for mounting the decorative plate on the vehicle body. In the following, when the two decorative plate clamps 50f and 50s are not distinguished, they are simply referred to as "decorative plate clamps 50". The same applies to other components.

[0041] The decorative plate clamp 50 is, for example, mounted on the inner side (i.e., the non-designed side) of the decorative plate. When the decorative plate is mounted on the vehicle body, the worker mounts the decorative plate from the inner side so that the decorative plate clamp 50 is engaged with the engaging hole claw formed on the vehicle body. Figure 2Press the front side of the paper toward the vehicle body. Figure 2 In the figure, the decorative plate is not shown, and only the head of the decorative plate clamp 50 engaged with the coupling hole claw is shown. In this example, the first decorative plate clamp 50f is installed on the upper part of the C-pillar 22, and the second decorative plate clamp 50s is installed on the lower part of the C-pillar 22.

[0042] As described above, the washer hose 42 is arranged so as to extend from the rear windshield washer 40 along the ceiling line 26 to the upper portion of the C-pillar 22 and then extend toward the lower portion of the vehicle along the C-pillar 22. Figure 2 The washer hose 42 is bent at an acute angle or about 90 degrees in the vicinity of the upper corner in a manner along the upper corner of the corner window glass 16. At the bent portion, if the shape of the washer hose 42 is not restrained, the washer hose 42 may swing and interfere with the curtain airbag 52, or the washer hose 42 may be bent and blocked.

[0043] Therefore, in this example, the washer hose 42 is divided into an upstream hose 44u and a downstream hose 44d at the front and rear of the bend. In addition, the upstream hose 44u is a hose arranged along the C-pillar 22, and the downstream hose 44d is a hose arranged along the ceiling line 26. The two hoses 44u and 44d are connected by a roughly L-shaped joint 46. The joint 46 is made of a hard resin or the like, and is a conduit component having an L-shaped passage. By configuring the joint 46 at the bend, the washer hose 42 around the bend is effectively prevented from swinging. In addition, by setting it as such a structure, the washer hose 42 at the bend is effectively prevented from being blocked.

[0044] The upstream hose 44u is mounted on the surface of the C-pillar 22 on the vehicle interior side through a plurality of hose clamps 60f and 60s. Here, the installation of the washer hose 42 to the vehicle body is implemented before the decorative panel is installed to the vehicle body. Therefore, if a part of the washer hose 42 is located near the coupling hole of the decorative panel, the washer hose 42 may be pressed and blocked by the decorative panel clamp 50. On the other hand, considering the width of the C-pillar 22, the coupling position of the hose clamp 60 cannot be greatly separated from the coupling position of the decorative panel clamp 50 in the vehicle front-rear direction. Therefore, in this example, the shape of the hose clamp 60 for mounting the washer hose 42 on the C-pillar 22 is studied.

[0045] Specifically, the hose clamp 60 includes a coupling portion 62, a connecting portion 64, and a retaining portion 66. The coupling portion 62 is a portion that includes a protrusion that engages with a coupling hole claw formed on the C-pillar 22 and is coupled to the C-pillar 22. The coupling portion 62 of the first hose clamp 60f is coupled to a position that is close to the lower side of the first decorative plate clamp 50f and closer to the first decorative plate clamp 50f than the second hose clamp 60s. The coupling portion 62 of the second hose clamp 60s is coupled to a position that is close to the upper side of the second decorative plate clamp 50s and closer to the second decorative plate clamp 50s than the first hose clamp 60f. Furthermore, the coupling portions of the two decorative plate clamps 50 and the coupling portions 62 of the two hose clamps 60 are arranged roughly in a straight line.

[0046] The connecting portion 64 is a part connecting the connecting portion 62 and the holding portion 66. The connecting portion 64 extends from the connecting portion 62 toward the vehicle rear side. In addition, the distal end of the connecting portion 64 is bent toward the vehicle vertical direction, in other words, toward the direction approaching the nearest trim plate clip 50.

[0047] The retaining portion 66 is a portion that retains the washer hose 42. Such a retaining portion 66 is, for example, a cylindrical object through which the washer hose 42 is inserted, or a clamp that clamps the washer hose 42. Here, as described above, since the connecting portion 64 extends from the coupling portion 62 to the rear side of the vehicle, the retaining portion 66 is offset to the rear side of the vehicle relative to the coupling portion 62. As a result, the straight line L2 connecting the two retaining portions 66 is offset to the rear side of the vehicle relative to the straight line L1 connecting the two decorative plate clamps 50. Thus, interference between the washer hose 42 and the decorative plate clamp 50 and blockage of the washer hose 42 can be effectively prevented.

[0048] In addition, if the holding portion 66 of the hose clamp 60 is far away from the trim clamp 50, the portion of the washer hose 42 not restrained by the holding portion 66 may swing and interfere with the trim clamp 50. Therefore, it is required that the holding portion 66 does not move far away from the trim clamp 50. Therefore, in this example, the hose clamp 60 is coupled to the vicinity of the trim clamp 50, and further, the end of the connecting portion 64 is bent so as to approach the nearest trim clamp 50. Thus, the washer hose 42 swinging near the trim clamp 50 and even the washer hose 42 being blocked by the trim clamp 50 can be effectively prevented.

[0049] In addition, the above-described structure is an example, and as long as the structure described in the first technical solution of the summary of the invention is provided, it can be appropriately changed. For example, the number and shape of the hose clamp 60 can also be appropriately changed.
