[0003] [Patent Document 1] Japanese Patent Publication No. 2023-89593 [Patent Document 2] Japanese Patent Publication No. 2022-32457 [Patent Document 3] JP 2019-14425 A Summary of the Invention [Problem to be solved by the invention]

[0004] In resin parts, high precision may be required for the dimensions or shape of the end portions of the resin parts due to design, safety, and other factors. For example, in the case of the pillar garnish described above, high precision may be required for the upper end portion of the pillar garnish in order to reduce the gap or step between the pillar garnish and the ceiling material. The present disclosure provides a resin part having an end portion formed with high precision.

[0005] A resin member according to one embodiment of the present disclosure is a resin member fastened to a structure by a fastening member, and comprises: a front wall facing the structure and extending in a first direction and a second direction intersecting the first direction; a first side wall protruding from the front wall toward the structure and extending in the first direction and a third direction intersecting the first and second directions; a base protruding from the front wall toward the structure and positioned spaced apart from a first end of the front wall in the first direction and spaced apart from the first side wall in the second direction, for holding the fastening member; and a first reinforcing piece protruding from the first side wall to face the front wall and connecting the base and the first side wall, wherein a portion of the first reinforcing piece is connected to the first side wall and is positioned closer to the first end than the base in the first direction. [Effects of the Invention]

[0006] According to the present disclosure, it is possible to provide a resin member having an end portion formed with high precision. [Brief explanation of the drawings]

[0007] [Figure 1] Schematic diagram showing the right side of the vehicle cabin [Figure 2] Cross-sectional view showing the AA section of Figure 1 [Figure 3] FIG. 1 is a perspective view showing a resin member; [Figure 4] FIG. 1 is a perspective view showing a resin member; DETAILED DESCRIPTION OF THE INVENTION

[0008] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings.

[0009] 1, a vehicle C includes a front pillar garnish 20a that covers the front pillar 10a, a center pillar garnish 20b that covers the center pillar 10b, a rear pillar garnish 20c that covers the rear pillar 10c, and a ceiling material 20d that covers the roof panel. In this embodiment, the front pillar garnish 20a, the center pillar garnish 20b, and the rear pillar garnish 20c are all resin members manufactured by injection molding.

[0010] The rear pillar garnish 20c is fastened to the rear pillar 10c (an example of a structure) via a clip 30c (an example of a fastening member). In this embodiment, the rear pillar garnish 20c will be described in detail, but the present invention is also applicable to the front pillar garnish 20a and the center pillar garnish 20b.

[0011] The rear pillar 10c extends along a first direction a. The rear pillar garnish 20c also extends along the first direction a and has a first end 24 that contacts the ceiling material 20d and a second end 25 on the opposite side.

[0012] As shown in FIG. 2, the rear pillar garnish 20c includes a front wall 21 facing the rear pillar 10c, a first side wall 22 protruding from the front wall 21 toward the rear pillar 10c, and a second side wall 23 protruding from the front wall 21 toward the rear pillar 10c and facing the first side wall 22. The front wall 21 is a plate-shaped member extending in a first direction a and a second direction b. The first side wall 22 is a plate-shaped member extending in the first direction a and a third direction c. The second side wall 23 is a plate-shaped member extending in the first direction a and a third direction c. The second direction b is a direction intersecting the first direction a. The third direction c is a direction intersecting the first direction a and the second direction b.

[0013] The rear pillar garnish 20c further includes a base 40 that holds the clip 30c. The base 40 protrudes from the front wall 21 toward the rear pillar 10c. The base 40 holds the clip 30c by various appropriate methods. In this embodiment, the base 40 has a base plate 41 that faces the rear pillar 10c and the front wall 21, and legs 42 that are provided between the front wall 21 and the base plate 41. The base plate 41 has a clip hole 41h that receives the base 31 of the clip 30c. The base 40 holds the clip 30c by receiving the base 31 of the clip 30c in the clip hole 41h. The head 32 of the clip 30c is fixed to the rear pillar 10c by, for example, a snap fit.

[0014] The rear pillar garnish 20c further includes a first reinforcing piece 51 facing the front wall 21. The first reinforcing piece 51 protrudes from the first side wall 22 and connects the base 40 and the first side wall 22 together.

[0015] The rear pillar garnish 20c may be formed of a thermoplastic resin, such as polypropylene (PP), ABS resin, polyethylene (PE), polystyrene (PS), acrylic resin, polycarbonate (PC), polyamide, polyethylene terephthalate (PET), or modified polyphenylene ether (PPE).

[0016] The shapes and positional relationship of the base 40 and the first reinforcing piece 51 will be described below with reference to FIGS.

[0017] The base 40 is spaced apart from the first end 24 of the front wall 21 in the first direction a. As described above, the first end 24 is in contact with the ceiling material 20d. This prevents the base 40 from interfering with the ceiling material 20d. The base 40 is also spaced apart from the first side wall 22 in the second direction b. This allows the base 40 to be positioned in a balanced manner at a midpoint between the first side wall 22 and the second side wall 23.

[0018] The legs 42 of the base 40 support the base plate 41 of the base 40 at an appropriate position in the third direction c. The legs 42 include a first wall 42a facing the first side wall 22, a second wall 42b facing the first wall 42a, and a third wall 42c connected between the first wall 42a and the second wall 42b. The legs 42 have a first opening 43 that opens toward the first end 24 in the first direction a. The first opening 43 is defined by the front wall 21, the base plate 41, the first wall 42a, the second wall 42b, and the third wall 42c. As shown in FIG. 2, the first opening 43 provides a space for accommodating the base 31 of the clip 30c.

[0019] The base 40 further has a support wall 44. The support wall 44 is a plate piece provided inside the base 40, i.e., inside the first opening 43. In this embodiment, the support wall 44 is disposed between the front wall 21 and the base plate 41 and is parallel to the front wall 21. As shown in FIG. 2 , the support wall 44 is located at approximately the same position as the first reinforcing piece 51 in the third direction c, and is connected to the first wall 42 a, the second wall 42 b, and the third wall 42 c. The support wall 44 increases the strength of the base 40.

[0020] The first reinforcing piece 51 includes a first portion 51a and a second portion 51b connected to the first portion 51a. In FIGS. 3 and 4, the boundary between the first portion 51a and the second portion 51b is indicated by a dashed line. The first portion 51a is located at the same position as the base 40 in the first direction a and is connected between the first side wall 22 and the first wall 42a of the base 40. The second portion 51b is connected to the first side wall 22 and is located closer to the first end portion 24 than the base 40 in the first direction a. The first reinforcing piece 51 includes the second portion 51b, and extends close to the first end portion 24. As a result, the first reinforcing piece 51 reinforces the vicinity of the first end portion 24 of the rear pillar garnish 20c and improves the precision (e.g., dimensional precision and shape precision) of the first end portion 24 of the rear pillar garnish 20c. For example, the first reinforcing piece 51 suppresses deformation of the portion of the first side wall 22 on the first end 24 side in a direction away from the base 40. As described above, the first end 24 is in contact with the ceiling material 20d. By improving the precision of the first end 24, the gap or step between the rear pillar garnish 20c and the ceiling material 20d is reduced, improving the design.

[0021] 1, the rear pillar garnish 20c is substantially rectangular in front view and has four corners c1, c2, c3, and c4. The rear pillar garnish 20c is particularly susceptible to deformation at the acute corner c1. In this embodiment, the first reinforcing piece 51 reinforces the vicinity of the first end 24 of the rear pillar garnish 20c, thereby suppressing deformation of the corner c1 and reducing the gap or step between the rear pillar garnish 20c and the ceiling material 20d.

[0022] The first reinforcing piece 51 is disposed at a height H from the front wall 21. In this embodiment, the first reinforcing piece 51 and the front wall 21 form a second opening 53. Like the first opening 43, the second opening 53 opens toward the first end 24 in the first direction a. The first opening 43 can be formed using a slide mold that can slide along the first direction a during injection molding. Because the second opening 53 opens in the same direction as the first opening 43, the above-mentioned slide mold can be used to form the second opening 53.

[0023] The first reinforcing piece 51 has a width W in the second direction b. The width W may be constant regardless of the position in the first direction a, or may vary depending on the position in the first direction a. In this embodiment, the width W of the first portion 51a is constant regardless of the position in the first direction a, and the width W of the second portion 51b becomes smaller as it approaches the first end 24. This prevents the first reinforcing piece 51 from interfering with the ceiling material 20d.

[0024] The first reinforcing piece 51 may be parallel to the front wall 21 or may be inclined relative to the front wall 21. In other words, the height H may be constant regardless of the position in the first direction a, or may vary depending on the position in the first direction a. In this embodiment, the height H increases as it approaches the first end 24 in the first direction a. This ensures the draft angle of the slide mold.

[0025] 4, in this embodiment, the rear pillar garnish 20c further includes a vertical wall 52 connected between the front wall 21 and the first reinforcing piece 51. More specifically, the vertical wall 52 is connected to an end 51c of the first reinforcing piece 51 on the opposite side from the first end 24 in the first direction a. The vertical wall 52 reinforces the first reinforcing piece 51.

[0026] 4, in this embodiment, the third wall 42c of the base 40 has a first exhaust port 42h. The first exhaust port 42h exhausts moisture and dust from the first opening 43 and prevents moisture and dust from accumulating within the first opening 43. Similarly, in this embodiment, the vertical wall 52 has a second exhaust port 52h. The second exhaust port 52h exhausts moisture and dust from the second opening 53 and prevents moisture and dust from accumulating within the second opening 53.

[0027] 3 and 4, in this embodiment, the rear pillar garnish 20c further includes a plurality of reinforcing pieces that protrude toward the rear pillar 10c to increase the strength of the rear pillar garnish 20c. The reinforcing pieces include a second reinforcing piece 61, a third reinforcing piece 62, a fourth reinforcing piece 63, and a fifth reinforcing piece 64.

[0028] The second reinforcing piece 61 protrudes from the first reinforcing piece 51 (more specifically, the first portion 51a) toward the rear pillar 10c. The second reinforcing piece 61 is connected to the base 40 and the first side wall 22. The second reinforcing piece 61 reinforces the rear pillar garnish 20c, further increasing the precision of the first end portion 24 of the rear pillar garnish 20c.

[0029] The third reinforcing piece 62 protrudes from the first reinforcing piece 51 (more specifically, the second portion 51b) toward the rear pillar 10c. The third reinforcing piece 62 is connected to the first side wall 22. The third reinforcing piece 62 is disposed between the first end portion 24 and the second reinforcing piece 61 in the first direction a. In other words, the third reinforcing piece 62 is positioned closer to the first end portion 24 than the second reinforcing piece 61. The third reinforcing piece 62 reinforces the area closer to the first end portion 24 of the rear pillar garnish 20c than the second reinforcing piece 61, thereby further improving the precision of the first end portion 24 of the rear pillar garnish 20c.

[0030] As described above, in this embodiment, the rear pillar garnish 20c (an example of a resin member) is fastened to the rear pillar 10c (an example of a structural body) by a clip 30c (an example of a fastening member). The rear pillar garnish 20c includes a front wall 21, a first side wall 22, a base 40, and a first reinforcing piece 51. The front wall 21 faces the rear pillar 10c and extends in a first direction a and a second direction b. The second direction b is a direction intersecting the first direction a. The first side wall 22 protrudes from the front wall 21 toward the rear pillar 10c and extends in the first direction a and a third direction c. The third direction c is a direction intersecting the first direction a and the second direction b. The base 40 protrudes from the front wall 21 toward the rear pillar 10c and is positioned away from the first end 24 of the front wall 21 in the first direction a and away from the first side wall 22 in the second direction b, and holds the clip 30c. The first reinforcing piece 51 protrudes from the first side wall 22 to face the front wall 21 and connects the base 40 to the first side wall 22. A second portion 51b, which is a part of the first reinforcing piece 51, is connected to the first side wall 22 and is located closer to the first end 24 than the base 40 in the first direction a. The second portion 51b of the first reinforcing piece 51 reinforces the vicinity of the first end 24 of the rear pillar garnish 20c, thereby improving the precision of the first end 24 of the rear pillar garnish 20c.

[0031] The base 40 may have a base plate 41 facing the front wall 21, and legs 42 provided between the front wall 21 and the base plate 41. The legs 42 may have a first opening 43 that opens toward the first end 24 in the first direction a. A second opening 53 that opens toward the first end 24 may be formed by the front wall 21 and the first reinforcing piece 51. The second opening 53 opens in the same direction as the first opening 43, so the slide mold used to form the first opening 43 can be used to form the second opening 53.

[0032] The rear pillar garnish 20c may further include a second reinforcing piece 61 that protrudes from the first reinforcing piece 51 toward the rear pillar 10c and connects the base 40 and the first side wall 22. The second reinforcing piece 61 reinforces the rear pillar garnish 20c, further increasing the precision of the first end 24 of the rear pillar garnish 20c.

[0033] The rear pillar garnish 20c may further include a third reinforcing piece 62 that protrudes from the first reinforcing piece 51 toward the rear pillar 10c, is disposed between the first end portion 24 and the second reinforcing piece 61 in the first direction a, and is connected to the first side wall 22. The third reinforcing piece 62 reinforces the area closer to the first end portion 24 of the rear pillar garnish 20c than the second reinforcing piece 61, thereby further improving the precision of the first end portion 24 of the rear pillar garnish 20c.

[0034] Although the present disclosure has been described above with reference to the embodiment, it should be understood that the present disclosure is not limited to the above embodiment and various modifications are possible without departing from the spirit of the invention. In particular, the multiple modifications described in this specification can be combined as desired.

[0035] In the above embodiment, the rear pillar garnish 20c is given as an example of a resin member, but the technology of the present disclosure is not limited to this and can be applied to any resin member that requires high precision in size or shape. [Explanation of symbols]
