[0008] Problems to be solved by the invention

[0009] However, the technology described in Patent Document 1 has no mechanical fastening parts such as bolts and clips, and therefore has low reliability. In addition, the rear end of the roof side molding is bonded to the rear fender panel and is difficult to remove. Furthermore, there is a problem that thermal expansion is not considered when the roof side molding is made of synthetic resin.

[0010] Furthermore, in the technology described in the above-mentioned Patent Document 2, since the anti-lifting claws provided on the pillar cover are inserted into the adhesive fixing the windshield to the front pillar and fixed, when the pillar cover is extended rearward to cover the roof side rails, the anti-lifting claws need to be inserted into the adhesive on the upper part of the roof side rails which is difficult for the operator to see, and there is a possibility that the workability may be deteriorated.

[0011] The present invention has been made in view of the above circumstances, and an object of the present invention is to easily and reliably mount a long pillar outer trim covering a front pillar and a roof side rail.

The installation structure of the outer decoration is characterized in that the outer edge of the pillar outer decoration in the vehicle width direction is fastened to the front pillar and the roof side rail by a mechanical fastening mechanism with the help of a retaining member that holds a door glass sealing rubber that abuts against the door glass.

[0014] In addition, the second scheme of the present invention provides an installation structure for a pillar outer decoration, which is characterized in that, based on the first scheme, a glass retaining component is fixed to the inner edge of the pillar outer decoration in the vehicle width direction, forming a space for inserting the edge of the roof glass, and a guide component is fixed to the edge of the roof glass to guide the insertion into the space.

[0015] A third aspect of the present invention provides a pillar outer trim mounting structure, which is based on the first aspect and is characterized in that the pillar outer trim is connected to the front pillar by a fastener.

[0016] In addition, the fourth scheme of the present invention provides an installation structure for a pillar outer decoration, which is characterized in that, based on the first scheme, a sealing rubber component is fixed to the inner end of the pillar outer decoration in the vehicle width direction, and the sealing rubber component has a first lip extending outward in the vehicle width direction and abutting against the windshield or the roof glass.

[0017] A fifth aspect of the present invention provides a pillar outer trim mounting structure according to the second aspect, wherein a cover abutting against the guide member is fitted to an inner end in the vehicle width direction of the glass holding member.

[0018] In addition, the sixth scheme of the present invention provides an installation structure for an outer pillar decoration, which is characterized in that, based on the fourth scheme, the sealing rubber component is a Y-shaped cross-section that branches from the second lip portion into two branches, namely, a fixed portion and the first lip portion, the fixed portion is bonded to the outer pillar decoration, and the first lip portion and the second lip portion abut against the windshield.

[0019] In addition, the seventh scheme of the present invention provides an installation structure for a pillar outer decoration, which is characterized in that, based on the first scheme, the pillar outer decoration uses a sealing component arranged along the door glass sealing rubber to seal between the front pillar and the roof side rail, and the drainage passage divided between the door glass sealing rubber and the sealing component has drainage outlets at the front end of the front pillar and the rear end of the roof side rail.

[0020] According to an eighth aspect of the present invention, there is provided a pillar outer garnish mounting structure, which is characterized in that, in addition to the first aspect, the pillar outer garnish has a wall thickness that gradually decreases from an inner edge toward an outer edge in a vehicle width direction.

[0021] It should be noted that the front pillar upper member 12 of the embodiment corresponds to the front pillar of the present invention, the front door 16 and the rear door 17 of the embodiment correspond to the frameless door of the present invention, and the bolt 25 of the embodiment corresponds to the mechanical fastening mechanism of the present invention.

[0022] Effects of the Invention

[0023] According to the first aspect of the present invention, the pillar outer decoration is installed along the front pillar sandwiched by the door glass and the windshield of the frameless door and the roof side rails sandwiched by the door glass and the roof glass. The outer edge of the pillar outer decoration in the vehicle width direction is fastened to the front pillar and the roof side rails by a mechanical fastening mechanism by means of a retainer that holds the door glass sealing rubber that abuts against the door glass, so that not only the long pillar outer decoration bent at the boundary between the front pillar and the roof side rail can be easily and reliably fixed, but also the pillar outer decoration can be thinned and lightened by reinforcing the rigidity of the pillar outer decoration with the rigidity of the retainer, and the door glass sealing rubber can be reliably supported by the retainer to improve the sealing performance of the pillar outer decoration.

[0024] In addition, according to the second scheme of the present invention, a glass retaining component that forms a space for inserting the edge of the roof glass is fixed to the inner edge of the pillar outer decoration in the vehicle width direction, and a guide component that guides the insertion into the space is fixed to the edge of the roof glass. Therefore, the assembly operation of the pillar outer decoration to the windshield or the roof glass can be carried out smoothly, and cracking of the edge of the windshield or the roof glass can be prevented.

[0025] Furthermore, according to the third aspect of the present invention, the pillar outer garnish is connected to the front pillar by the fastener, so that the fixing strength of the pillar outer garnish can be further improved.

[0026] According to the fourth aspect of the present invention, a sealing rubber member is fixed to the inner end of the pillar outer decoration in the vehicle width direction, and the sealing rubber member has a first lip portion extending outward in the vehicle width direction and abutting against the windshield or the roof glass, thereby preventing water from entering from the gap between the windshield or the roof glass and the pillar outer decoration, and improving the assembly performance of the pillar outer decoration to the windshield or the roof glass. In particular, the step difference between the windshield and the pillar outer decoration can be reduced at the front pillar portion to reduce air resistance.

[0027] According to the fifth aspect of the present invention, the cover that contacts the guide member is fitted to the inner end of the glass holding member in the vehicle width direction, so that the pillar outer trim can be reliably fixed to the windshield or the roof glass.

[0028] In addition, according to the sixth embodiment of the present invention, the sealing rubber component is a Y-shaped cross-section that is bifurcated from the second lip portion into two branches, namely, a fixed portion and a first lip portion, the fixed portion is bonded to the pillar outer decorative member, and the first lip portion and the second lip portion are in contact with the windshield. Therefore, the reaction force borne by the first lip portion pressed against the windshield causes the second lip portion to be pressed against the windshield, thereby improving the sealing performance of the sealing rubber component.

[0029] In addition, according to the seventh embodiment of the present invention, the pillar outer decoration utilizes a sealing component arranged along the door glass sealing rubber to seal between the front pillar and the roof side rail. Since the drainage passage defined by the door glass sealing rubber and the sealing component has drainage ports at the front end of the front pillar and the rear end of the roof side rail, not only can the door glass sealing rubber and the sealing component be configured as a double layer to reliably prevent water from entering the vehicle cabin, but water that passes through the door glass sealing rubber can also be discharged from the drainage port via the drainage passage defined by the door glass sealing rubber and the sealing component.

[0030] In addition, according to the 8th scheme of the present invention, the wall thickness of the pillar outer decoration gradually decreases from the inner edge to the outer edge in the vehicle width direction, so the air flow from the windshield to the door glass becomes smooth and the air resistance is reduced. Especially on rainy days, raindrops are not easy to adhere to the windshield, which can provide a good field of vision. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] The following is based on Figure 1 to Figure 7 The embodiment of the present invention will be described. It should be noted that the front-rear direction, the left-right direction (vehicle width direction), and the up-down direction in this specification are defined based on the occupant sitting in the driver's seat.

[0064] First Embodiment

[0065] like Figure 1 As shown, the automobile includes a front pillar lower member 11, a front pillar upper member 12, a center pillar 13, and a rear pillar 14. The front pillar upper member 12 extends rearward and upward from the upper end of the front pillar lower member 11, and a roof side rail 15 extends rearward from the upper end of the front pillar upper member 12 and is connected to the upper end of the center pillar 13 and the upper end of the rear pillar 14. A front door 16 as a frameless door is provided in a door opening defined by the front pillar lower member 11, the front pillar upper member 12, the front half of the roof side rail 15, and the center pillar 13, and a rear door 17 as a frameless door is provided in a door opening defined by the center pillar 13, the rear half of the roof side rail 15, and the rear pillar 14. The left and right front pillar upper members 12 are connected by a windshield 18, and the left and right roof side rails 15 are connected by a roof glass 19.

[0066] The outer surfaces of the front pillar upper member 12 and the roof side rail 15 in the vehicle width direction are covered by an integrally formed long pillar outer trim 20. The pillar outer trim 20 is formed by a front pillar portion 20A covering the front pillar upper member 12 and a roof side rail portion 20B covering the roof side rail 15, and is bent into a "ヘ" shape at the boundary between the two. The cross section of the front pillar portion 20A (see Figure 2 ), and the cross section of the roof side rail portion 20B (refer to Figure 3 ) are similar, but the details are different.

[0067] like Figure 1 to Figure 3 As shown, the pillar outer garnish 20 made of glass fiber reinforced thermosetting resin is manufactured by, for example, the SMC method, and has a constant arc-shaped cross-section from the front end to the rear end thereof, and its wall thickness gradually becomes thinner as it goes from the inner end in the vehicle width direction to the outer end in the vehicle width direction. At the front pillar portion 20A along the front pillar upper member 12, the inner end in the vehicle width direction of the pillar outer garnish 20 faces the windshield 18, and the outer end in the vehicle width direction faces the door glass 21 of the front door 16. On the other hand, at the roof side rail portion 20B along the roof side rail 15, the inner end in the vehicle width direction of the pillar outer garnish 20 faces the roof glass 19, and the outer end in the vehicle width direction faces the door glass 21 of the front door 16 or the door glass 22 of the rear door 17.

[0068] like Figure 2 , Figure 3 and Figure 7 As shown, the metal retaining member 23 used to install the pillar outer decoration member 20 on the front pillar upper member 12 and the roof side rail 15 is a long member with a U-shaped cross-section having an upper wall 23a, a bottom wall 23b and a lower wall 23c, and the upper wall 23a is fixed to the outer end of the pillar outer decoration member 20 in the vehicle width direction using an adhesive 24.

[0069] In addition, a plurality of bolt holes are formed in the bottom wall 23b of the retainer 23, one bolt hole located at the curved portion of the boundary between the front pillar upper member 12 and the roof side rail 15 is a circular hole 23d serving as a reference hole, and the other bolt holes are long holes 23e extending in the front-rear direction. The retainer 23 is fastened to the front pillar upper member 12 and the roof side rail 15 by bolts 25 penetrating the circular hole 23d and the long hole 23e.

[0070] like Figure 1 and Figure 6 As shown in FIG. 1 , a flange 20a is protruded from the front end of the pillar outer garnish 20, and a bolt hole 20b having a larger diameter than the round hole 23d and the long hole 23e of the retainer 23 is formed on the flange 20a. The front end of the pillar outer garnish 20 is fastened to the lower end of the front pillar upper member 12 by a bolt 26 passing through the bolt hole 20b. In addition, an end wall 20c is provided at the rear end of the pillar outer garnish 20, and the rear end of the pillar outer garnish 20 is fastened to the rear end of the roof side rail 15 by a bolt 27 passing through the bolt hole 20d formed in the end wall 20c. At this time, the bolt 27 has a cylindrical guide portion 27c longer than the wall thickness of the end wall 20c between the head portion 27a and the shaft portion 27b, and the guide portion 27c is fitted into the bolt hole 20d of the pillar outer garnish 20 in a manner that allows for forward and backward sliding.

[0071] like Figure 2 to Figure 4 As shown, a door glass sealing rubber 28 is provided inside a retaining member 23 bonded to a pillar outer decorative member 20, and a door glass sealing rubber 29 is provided at the outer ends in the vehicle width direction of the front pillar upper member 12 and the roof side rail 15. The door glass sealing rubbers 28 and 29 abut against the upper ends of the door glasses 21 and 22 of the front door 16 and the rear door 17 to perform a sealing function.

[0072] The front pillar portion 20A of the pillar outer trim 20 is not only fixed to the retainer 23 using the adhesive 24, but is also fixed to the front pillar upper member 12 (see FIG. 1 ) using a planar fastener 30 disposed at an inner side in the vehicle width direction relative to the adhesive 24. Figure 2 ).

[0073] In the pillar outer garnish 20, a foam seal 31 is applied in a linear shape along the inner side of the retainer 23 in the vehicle width direction, and the space between the front pillar upper member 12 and the roof side rail 15 is sealed by the foam seal 31. As a result, a drainage passage 32 is formed between the retainer 23 and the foam seal 31 along the longitudinal direction of the pillar outer garnish 20, and the drainage passage 32 communicates with the outside at drainage ports 33 and 34 at the front and rear ends.

[0074] The outer edges of the windshield 18 and the roof glass 19 in the vehicle width direction are fixed to the front pillar upper member 12 or the roof side rail 15 using an adhesive 35. At this time, the adhesive 35 is blocked by a rubber seal 36 to prevent leakage to the central transparent portion of the windshield 18 and the roof glass 19.

[0075] The sealing rubber component 37 with a Y-shaped cross-section arranged at the inner end of the pillar outer decoration 20 in the vehicle width direction includes a second lip portion 37a and a fixing portion 37b and a first lip portion 37c that are bifurcated from the second lip portion 37a. The fixing portion 37b is bonded to the pillar outer decoration 20 using an adhesive 38, and the first lip portion 37c and the second lip portion 37a abut against the windshield 18 or the roof glass 19.

[0076] In addition, the roof side rail portion 20B of the pillar outer trim 20 (see Figure 3 and Figure 5 ), a plurality of glass holding members 39 formed of a metal plate bent into a crank shape are bonded to the vicinity of the sealing rubber member 37 of the pillar outer trim 20 using an adhesive 40, and a cover 41 formed of a synthetic resin with a U-shaped cross section is fitted to the top end of these glass holding members 39. On the other hand, a plurality of guide members 42 formed of a metal plate bent into an L shape are bonded to the outer end in the vehicle width direction of the roof glass 19 fitted between the sealing rubber member 37 of the pillar outer trim 20 and the cover 41 using an adhesive 43. The length W2 of the glass holding member 39 and the cover 41 in the front-rear direction is set shorter than the length W1 of the guide member 42 in the front-rear direction.

[0077] like Figure 1 As shown, a camera 44 for photographing the rear of the vehicle body is provided at the front upper portion of the outer surface in the vehicle width direction of the front door 16 .

[0078] Next, the operation of the embodiment of the present invention having the above-described configuration will be described.

[0079] A retainer 23 for retaining door glass seal rubbers 28 that abut against door glasses 21 and 22 of the front door 16 and the rear door 17 is bonded along the outer edge of the long pillar outer garnish 20 covering the front pillar upper member 12 and the roof side rail 15 in the vehicle width direction, and the retainer 23 is fastened to the front pillar upper member 12 and the roof side rail 15 by bolts 25, so that the long pillar outer garnish 20 can be easily and reliably fixed to the front pillar upper member 12 and the roof side rail 15. At this time, the pillar outer garnish 20 is connected to the front pillar upper member 12 by the planar fastener 30 in addition to the bolts 25, so that not only the fixing strength of the pillar outer garnish 20 can be further improved, but also the step difference between the windshield 18 and the pillar outer garnish 20 can be reduced to reduce air resistance.

[0080] Furthermore, by reinforcing the rigidity of the long pillar outer garnish 20 with the rigidity of the retainer 23, not only can the pillar outer garnish 20 be thinner and lighter, but the retainer 23 can also reliably support the door glass seal rubber 28 to improve the sealing performance of the pillar outer garnish 20. In particular, since the pillar outer garnish 20 is made of synthetic resin and the metal retainer 23 is bonded to the pillar outer garnish 20, it is possible to achieve further weight reduction, improved productivity, and improved design freedom compared to the case where both the pillar outer garnish 20 and the retainer 23 are made of metal.

[0081] In addition, when the long pillar outer decoration 20 is made of synthetic resin, although the dimensional error during manufacturing and the thermal expansion / contraction caused by temperature changes cannot be ignored, the retaining member 23 bonded to the pillar outer decoration 20 is formed with a circular hole 23d at a position corresponding to the curved portion of the boundary between the front pillar upper member 12 and the roof side rail 15, and a long hole 23e long in the front-to-back direction is formed at a position corresponding to the front pillar upper member 12 and the roof side rail 15. Therefore, the pillar outer decoration 20 can be positioned with high accuracy relative to the front pillar upper member 12 and the roof side rail 15. At the same time, even if the length of the pillar outer decoration 20 including the retaining member 23 changes due to dimensional error or thermal expansion / contraction, the change in length can be absorbed by the gap between the bolt 25 and the long hole 23e, and the pillar outer decoration 20 can be reliably fixed.

[0082] In addition, the influence of dimensional errors during the manufacture of the pillar outer decoration 20 and thermal expansion / contraction caused by temperature changes are significant at the front end of the curved portion of the front pillar upper component 12 away from the boundary between it and the roof side rail 15, but the front end of the outer decoration 20 is fastened to the lower end of the front pillar upper component 12 by means of bolts 26 passing through bolt holes 20b having a larger diameter than the circular holes 23d and the long holes 23e of the retaining member 23. Therefore, even if the length of the pillar outer decoration 20 changes due to dimensional errors and thermal expansion / contraction, its length change can be absorbed to prevent the pillar outer decoration 20 from floating up.

[0083] In addition, the rear end of the pillar outer decoration 20 is fastened to the rear end of the roof side rail 15 by means of bolts 27 arranged in the front-to-rear direction, but the bolt hole 20d of the pillar outer decoration 20 and the cylindrical guide portion 27c formed between the head 27a and the shaft portion 27b of the bolt 27 are engaged in a manner that allows free sliding back and forth. Therefore, even if the length of the pillar outer decoration 20 changes due to dimensional error, thermal expansion / thermal contraction, its length change can be absorbed to prevent the pillar outer decoration 20 from floating up.

[0084] In addition, the thickness of the pillar outer garnish 20 gradually decreases from the inner edge to the outer edge in the vehicle width direction, so the air flow from the windshield 18 to the door glass 21 of the front door 16 becomes smooth and the air resistance is reduced. In particular, on rainy days, raindrops are less likely to adhere to the windshield 18, which can provide a good field of vision. In addition, since the pillar outer garnish 20 is made of thermosetting resin reinforced with glass fiber, the thermal expansion coefficient of the pillar outer garnish 20 can be suppressed to a minimum, and thermal expansion can be easily dealt with.

[0085] Furthermore, in order to assemble the pillar outer decoration 20 to the roof glass 19, the outer end portion of the roof glass 19 in the vehicle width direction needs to be fitted into the space between the sealing rubber component 37 and the glass retaining component 39 provided at the inner end portion of the pillar outer decoration 20 in the vehicle width direction. However, since a guide component 42 with an L-shaped cross-section is provided at the outer end portion of the roof glass 19 in the vehicle width direction, the above-mentioned assembly operation can be carried out smoothly and cracking of the edge of the roof glass 19 can be prevented.

[0086] At this time, since the cover 41 that contacts the guide member 42 is fitted to the inner end of the glass holding member 39 in the vehicle width direction, the pillar outer decoration 20 can be reliably fixed to the roof glass 19. In addition, since the length W2 of the glass holding member 39 in the front-rear direction is shorter than the length W1 of the guide member 42 in the front-rear direction, it is not necessary to strictly position the pillar outer decoration 20 relative to the roof glass 19, and the assembly work of the pillar outer decoration 20 becomes easy.

[0087] In addition, a sealing rubber component 37 for sealing between the windshield 18 and the roof glass 19 is fixed to the inner edge of the pillar outer decoration 20 in the vehicle width direction. The sealing rubber component 37 has a first lip portion 37c extending from the inner side to the outer side in the vehicle width direction and abutting against the windshield 18 and the roof glass 19. Therefore, when the pillar outer decoration 20 is assembled to the windshield 18 and the roof glass 19, the first lip portion 37c can be used as a guide to smoothly assemble the pillar outer decoration 20. Moreover, the first lip portion 37c is configured in a manner that does not increase the step difference between the windshield 18 and the roof glass 19 and the pillar outer decoration 20, thereby reducing air resistance.

[0088] In particular, the camera 44 for photographing the rear of the vehicle body is arranged outside the front door 16 in the vehicle width direction, so that air can flow smoothly from the windshield 18 to the door glass 21, and raindrops are difficult to adhere to the camera 44, thereby ensuring the camera performance of the camera 44.

[0089] In addition, the sealing rubber component 37 has a Y-shaped cross-section that is bifurcated from the second lip portion 37a into two branches, namely a fixed portion 37b and a first lip portion 37c. The fixed portion 37b is bonded to the pillar outer decoration 20, and the first lip portion 37c and the second lip portion 37a are in contact with the windshield 18 and the roof glass 19. Therefore, the reaction force borne by the first lip portion 37c pressed against the windshield and the roof glass 19 can press the second lip portion 37a against the windshield 18 and the roof glass 19, thereby improving the sealing performance of the sealing rubber component 37.

[0090] In addition, in the pillar outer trim 20, the front pillar upper member 12 and the roof side rail 15 are sealed by the foam seal 31 arranged along the door glass seal rubber 28, and the drainage passage 32 defined between the door glass seal rubber 28 and the foam seal 31 has drainage ports 33 and 34 at the front end of the front pillar upper member 12 and the rear end of the roof side rail 15. Therefore, not only can the door glass seal rubber 28 and the foam seal 31 be configured as a double layer to reliably prevent water from entering the vehicle cabin, but also the water passing through the door glass seal rubber 28 can be discharged from the drainage ports 33 and 34 via the drainage passage 32 defined between the door glass seal rubber 28 and the foam seal 31.

[0091] As mentioned above, although embodiment of this invention was described, this invention can make various design changes in the range which does not deviate from the summary.

[0092] For example, the mechanical fastening mechanism of the present invention is not limited to the bolts 25 of the embodiment, and may be another type of mechanical fastening mechanism such as a clip.
