Description

[Technical Field]

[0001] The present disclosure relates to an in-vehicle bracket for mounting an in-vehicle device to a mounting panel. [Background technology]

[0002] In-vehicle devices such as an in-vehicle camera for an electronic rearview mirror, an in-vehicle camera for a backing monitor, and a nozzle for cleaning the camera are attached to a vehicle by an in-vehicle bracket. One example of the in-vehicle bracket includes a plastic part and an elastomer part (see, for example, Patent Document 1).

[0003] The plastic part has a lidded cylindrical shape with a lid and a flange. The lid and flange each have a through-hole. The vehicle-mounted camera is inserted into the through-hole of the lid and fastened to the lid with a fastening screw. The plastic part is releasably fixed to the vehicle body sheet metal by a mounting claw inserted into the through-hole of the flange.

[0004] The elastomer portion is molded integrally with the flange portion so as to fill the gap between the mounting claw and the inner wall that defines the through-hole in the flange portion. The elastomer portion fills the gap between the flange portion and the vehicle body sheet metal on the outer periphery of the plastic portion. The elastomer portion prevents water from entering through the through-hole in the flange portion and through the gap between the flange portion and the vehicle body sheet metal.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-35693 Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned vehicle-mounted bracket secures the vehicle-mounted camera to the cover of the plastic part with screws. Because the plastic part and the vehicle-mounted camera are fastened together with fastening screws, gaps exist between the fastening screws and the plastic part, between the plastic part and the vehicle-mounted camera, and between the vehicle-mounted camera and the fastening screws. The gaps between the plastic part and the vehicle-mounted camera are more likely to allow water to penetrate through the gaps than gaps filled in the elastomer part. Therefore, there is still room for improvement in the sealing performance of the vehicle-mounted bracket, which is located between the vehicle body sheet metal and the vehicle-mounted equipment. [Means for solving the problem]

[0007] According to one aspect of the present disclosure, an in-vehicle bracket for mounting an in-vehicle device to a mounting panel of a vehicle includes a bracket main body and a sealing portion made of a soft material and integral with the bracket main body. The bracket main body includes a flange with a mounting portion configured to mount the in-vehicle device, and a leg extending from the flange, the leg having a fastening portion configured to be mounted to the mounting panel. The sealing portion includes: a water-stopping portion configured to cover the flange and extend around the flange to seal off water between the flange and the mounting panel; and a crimping portion having a mounting hole for mounting the in-vehicle device to the mounting portion, the crimping portion being configured to seal off water between the flange and the in-vehicle device around the mounting hole.

[0008] According to the above configuration, the vehicle-mounted bracket is interposed between the mounting panel and the vehicle-mounted device. The water-stopping portion of the vehicle-mounted bracket seals off water between the flange and the mounting panel. The mounting hole of the vehicle-mounted bracket allows the vehicle-mounted device to be mounted to the bracket main body. The mounting hole of the vehicle-mounted bracket is also positioned in the seal portion so that the seal portion seals off water between the flange and the vehicle-mounted device. In this way, the seal portion formed integrally with the bracket main body seals off water between the flange and the mounting panel and between the flange and the vehicle-mounted device. In particular, the seal portion seals off water between the flange and the vehicle-mounted device, improving the sealing performance of the vehicle-mounted bracket.

[0009] In the vehicle-mounted bracket, the sealing portion may be formed integrally with the crimping portion and the water-stopping portion. With this configuration, a gap is less likely to form between the bracket main body and the sealing portion. This improves the sealing performance between the bracket main body and the sealing portion. Furthermore, the vehicle-mounted bracket is easier to handle than when the bracket main body is a separate member from the sealing portion. Furthermore, because the portion with the mounting hole and the water-stopping portion are integrated, the vehicle-mounted bracket is even easier to handle.

[0010] In the vehicle-mounted bracket, the crimping portion may be disposed around the entire periphery of the mounting hole and protrude so as to be crimped to the vehicle-mounted device. With this configuration, the crimping portion improves watertightness between the vehicle-mounted device and the flange portion.

[0011] In the vehicle-mounted bracket, the water stop portion may be disposed closer to the flange than the fastening portion in the extension direction of the leg. With this configuration, the water stop portion is disposed closer to the flange than the fastening portion, and therefore the water stop portion is more easily pressed against the surface of the mounting panel when the vehicle-mounted bracket is attached to the mounting panel. This improves the sealing performance of the water stop portion between the flange and the mounting panel.

[0012] In the vehicle-mounted bracket, the water blocking portion may include a lip base end portion joined to the bracket main body portion, and a lip tip end portion extending from the lip base end toward the outside of the bracket main body portion. The lip tip end portion may not include a parting line on a surface that contacts the mounting panel, and the boundary between the lip base end portion and the lip tip end portion may include a closed-loop parting line that surrounds the flange portion in a portion that faces the mounting panel.

[0013] According to the above configuration, the surface of the lip tip that comes into contact with the mounting panel does not have a parting line. Therefore, compared to when the lip tip has a parting line, the sealing performance of the watertight portion between the flange and the mounting panel is improved. Furthermore, the boundary between the lip base end and the lip tip is a closed ring-shaped parting line. Therefore, even with an undercut-shaped watertight portion, the lip tip can be demolded by forcibly removing it from a mold that conforms to the contours of the lip tip.

[0014] The vehicle-mounted bracket may have parting lines aligned in a circumferential direction of the flange portion on a portion facing the mounting panel. With the above configuration, even if the watertight portion has an undercut shape, the split mold can slide along the outer shape of the lip base end when the lip base end is released. This allows the lip base end to be manufactured in a way that accommodates the forced removal of the lip tip. This reduces the design load on the lip tip, which requires forced removal.

[0015] In the above-mentioned vehicle-mounted bracket, the water-stopping portion comprises a lip base end portion that joins to the bracket main body portion, and a lip tip end portion that extends from the lip base end toward the outside of the bracket main body portion, and the joint portion between the lip base end and the bracket main body portion may have an uneven shape that is repeated in the circumferential direction of the flange portion.

[0016] According to the above configuration, the area of ​​the joint at the lip base end that comes into contact with the bracket main body increases by the amount of the repeated concave and convex portions at the joint, thereby increasing the strength with which the waterproofing part is joined to the bracket main body.

[0017] In the above-mentioned vehicle-mounted bracket, the leg portion may have a plurality of stoppers lined up in the circumferential direction of the leg, the plurality of stoppers protruding outward from the outer peripheral surface of the leg, and the plurality of stoppers may be configured to determine the relative position of the leg with respect to the surface of the mounting panel, the water-stopping portion may be a lip portion having a lip base end joined to the bracket main body portion and a lip tip end extending from the lip base end toward the outside of the bracket main body portion, the leg portion may have a picking portion provided over the entire circumferential direction of the leg, the picking portion extending to the lip base end, and while the picking portion extends to the lip base end, the plurality of stoppers do not extend to the lip base end, so that the tip of the picking portion is positioned outward from the tips of the plurality of stoppers.

[0018] With the above configuration, because the lip base end is spaced outward from the stopper, the boundary between the lip base end and the leg portion is defined by the convex portion throughout the entire circumferential direction. As a result, the base end of the bending range of the lip portion is defined by the convex portion throughout the entire circumferential direction. Furthermore, when the mounting panel abuts the stopper, the vertical distance between the mounting panel and the lip base end is constant throughout the entire circumferential direction. This reduces circumferential variation in bending stress acting on the lip base end, uniforming the surface pressure acting on the lip tip end in the circumferential direction and reducing partial reductions in surface pressure in the circumferential direction. [Effects of the Invention]

[0019] The vehicle-mounted bracket improves the sealing performance between the mounting panel and the vehicle-mounted equipment. [Brief explanation of the drawings]

[0021] (First embodiment) A vehicle-mounted bracket according to a first embodiment will be described with reference to FIGS. [Vehicle bracket] As shown in Figure 1, the vehicle-mounted bracket includes a bracket main body 11 made of hard resin and a seal portion 21 made of soft material. The vehicle-mounted bracket is configured such that the bracket main body 11 and seal portion 21 are integrally formed. The vehicle-mounted bracket may be a two-color molded product in which the bracket main body 11 and seal portion 21 are integrally formed, or may be an insert-molded product in which the seal portion 21 is molded into the bracket main body 11. The vehicle-mounted bracket may also be a pressure-molded product in which the seal portion 21 is heat-bonded to the bracket main body 11.

[0022] An example of the hard resin forming the bracket body 11 is at least one selected from the group consisting of polybutylene terephthalate (PBT), polyamide (PA), and polyoxymethylene (POM). The hard resin may be a glass fiber reinforced resin containing glass fibers.

[0023] The soft material forming the seal portion 21 may be a thermoplastic elastomer, ethylene propylene rubber (EPDM), or silicone rubber that is softer than the constituent material of the bracket main body 11. An example of the thermoplastic elastomer is at least one selected from the group consisting of ester-based elastomers, amide-based elastomers, olefin-based elastomers, styrene-based elastomers, and vinyl chloride-based elastomers.

[0024] [Bracket body 11] The bracket main body 11 includes a flange 11A (see FIG. 3) and a leg 12. The bracket main body 11 includes a fastening portion 13 and a stopper 18 (see FIGS. 4 and 5) on the leg 12. The bracket main body 11 includes a first mounting portion 14 and a second mounting portion 15 on the flange 11A.

[0025] The leg portion 12 has a rectangular cylindrical shape. The leg portion 12 has a plurality of fastening portions 13, and each fastening portion 13 has two stoppers 18 (see Figure 4). The fastening portions 13 have a claw-like shape that protrudes outward from the leg portion 12. The fastening portions 13 have a cantilever shape that can bend within the tube of the leg portion 12. The leg portion 12 that is inserted into the mounting panel 31 of the vehicle bends the fastening portion 13 so that the leg portion 12 passes through the insertion hole of the mounting panel 31. The fastening portion 13 has a slope (see Figure 5) at the tip of the cantilever that protrudes more outward from the leg portion 12 as it approaches the tip of the leg portion 12.

[0026] The stoppers 18 are distributed around the circumferential direction of the leg 12. The stoppers 18 are protrusions that protrude outward from the outer peripheral surface of the leg 12. The stoppers 18 are arranged closer to the flange 11A than the fastening portions 13 in the direction in which the leg 12 extends. A gap corresponding to the thickness of the mounting panel 31 is formed between the stoppers 18 and the inclined surfaces of the fastening portions 13 in the direction in which the leg 12 extends. When the leg 12 is inserted into the mounting panel 31, the stoppers 18 abut against the surface of the mounting panel 31. The inclined surfaces of the fastening portions 13 that are inserted through the insertion holes of the mounting panel 31 press the back surface of the mounting panel 31 toward the stoppers 18 while restoring the bending of the fastening portions 13. This positions the leg 12 on the mounting panel 31.

[0027] Flange portion 11A has a plate shape that protrudes toward the inside of leg portion 12. The front surface of flange portion 11A faces camera cleaning nozzle 33 and in-vehicle camera 34. The back surface of flange portion 11A is the surface opposite to the front surface of flange portion 11A and faces the inside of leg portion 12.

[0028] The first mounting portion 14 is disposed on the surface of the flange portion 11A. The first mounting portion 14 has a plate shape that borders the first insertion hole 14H. The first insertion hole 14H penetrates the flange portion 11A of the bracket main body 11. A camera cleaning nozzle 33 (see FIG. 2), which is an example of an in-vehicle device, is inserted through the first insertion hole 14H. The first mounting portion 14 is exposed to the outside of the in-vehicle bracket from the seal portion 21. The camera cleaning nozzle 33 is attached to the first mounting portion 14. The camera cleaning nozzle 33 is positioned on the first mounting portion 14 by a locking claw or the like of the camera cleaning nozzle 33.

[0029] The second mounting portion 15 is disposed on the surface of the flange portion 11A. The second mounting portion 15 has a plate shape that borders the second insertion hole 15H. The second insertion hole 15H penetrates the flange portion 11A of the bracket main body 11. An in-vehicle camera 34 (see FIG. 2), which is an example of an in-vehicle device, is inserted through the second insertion hole 15H. The second mounting portion 15 is exposed to the outside of the in-vehicle bracket from the seal portion 21. The in-vehicle camera 34 is mounted to the second mounting portion 15. The in-vehicle camera 34 is positioned on the second mounting portion 15 by a locking claw of the in-vehicle camera 34 or the like.

[0030] [Seal part 21] 1, the seal portion 21 has a shape that covers the surface of the flange portion 11A and extends around the flange portion 11A. The seal portion 21 includes a lip portion 22, which is an example of a watertight portion, and a main body seal portion 23.

[0031] The lip portion 22 is a tongue-shaped body having an undercut shape. The lip portion 22 surrounds the leg portion 12 over the entire circumferential direction of the leg portion 12. The lip portion 22 protrudes from the outer peripheral surface of the leg portion 12 toward the outside of the leg portion 12 and in a direction inclined with respect to the extension direction of the leg portion 12.

[0032] The body seal portion 23 covers the flange portion 11A so as to frame the entire periphery of the first mounting portion 14 and the entire periphery of the second mounting portion 15. The body seal portion 23 includes a first crimp portion 234 and a second crimp portion 235.

[0033] The first crimping portion 234 protrudes outward from the main body seal portion 23 in the thickness direction of the main body seal portion 23. The first crimping portion 234 is a protrusion that borders the first mounting portion 14. The first crimping portion 234 is an opening edge that borders the entire periphery of the first mounting hole that penetrates the main body seal portion 23. The first mounting hole defined by the first crimping portion 234 exposes the first mounting portion 14 from the seal portion 21.

[0034] 2, the amount of protrusion of the first crimping portion 234 is set so that, when the camera cleaning nozzle 33 is positioned on the first attachment portion 14, the first crimping portion 234 is crushed and crimped by the camera cleaning nozzle 33 in the protruding direction of the first crimping portion 234. As a result, the first crimping portion 234 seals off water between the camera cleaning nozzle 33 and the flange portion 11A of the bracket main body 11.

[0035] Returning to FIG. 1 , the second crimping portion 235 protrudes outward from the main body seal portion 23 in the thickness direction of the main body seal portion 23. The second crimping portion 235 is a protrusion that borders the second mounting portion 15. The second crimping portion 235 is an opening edge that borders the entire periphery of the second mounting hole that penetrates the main body seal portion 23. The second mounting hole defined by the second crimping portion 235 exposes the second mounting portion 15 from the seal portion 21.

[0036] 2, the amount of protrusion of the second crimping portion 235 is set so that, when the vehicle-mounted camera 34 is positioned on the second attachment portion 15, the second crimping portion 235 is crushed and crimped by the vehicle-mounted camera 34 in the protruding direction of the second crimping portion 235. As a result, the second crimping portion 235 seals off water between the vehicle-mounted camera 34 and the flange portion 11A of the bracket main body 11.

[0037] [Lip part 22] Fig. 3 shows a planar structure of the vehicle-mounted bracket as viewed from a viewpoint opposite the back surface of flange portion 11A. Fig. 4 shows a portion 221 of lip portion 22 as viewed from a viewpoint opposite the back surface of flange portion 11A. That is, Fig. 4 shows an enlarged view of the portion of lip portion 22 that faces mounting panel 31.

[0038] As shown in FIG. 3, the lip portion 22 includes a joining portion 25 , a first parting line 26 , and a second parting line 27 . The joint 25 is a portion of the lip portion 22 that is joined to the leg portion 12. The joint 25 has an uneven shape that is repeated in the circumferential direction of the flange 11A. The outer peripheral surface of the leg portion 12 has recesses that are repeated in the circumferential direction of the flange 11A. The joint 25 is a boundary between the lip portion 22 and the outer peripheral surface of the leg portion 12 that includes the recesses. The joint 25 is a portion of the soft material that makes up the lip portion 22 that comes into contact with the hard resin that makes up the leg portion 12. When forming the lip portion 22, part of the lip portion 22 is embedded in the recesses of the leg portion 12, thereby forming the uneven shape of the joint 25. The uneven shape of the joint 25 may be evenly distributed in the circumferential direction of the lip portion 22.

[0039] As a result, the contact area of ​​joint 25 of lip portion 22 with bracket main body 11 is increased by the amount of repetition of the uneven shape. Joint 25 of lip portion 22 also increases the strength with which lip portion 22 is joined to bracket main body 11, preventing lip portion 22 from peeling off from bracket main body 11.

[0040] First parting line 26 has a closed ring shape that extends around the entire circumference of lip portion 22. First parting line 26 is a step formed by dividing the mold used to form lip portion 22. Second parting line 27 has a straight line that extends in the radial direction of lip portion 22. Second parting line 27 is also a step formed by dividing the mold used to form lip portion 22.

[0041] 4, the lip portion 22 has a lip tip portion 22T and a lip base portion 22B. The lip tip portion 22T is a portion of the lip portion 22 closer to the tip of the lip portion 22 than the first parting line 26. The lip base portion 22B is a portion of the lip portion 22 closer to the base of the lip portion 22 than the first parting line 26 and includes a joint portion 25. The first parting line 26 is the boundary between the lip tip portion 22T and the lip base portion 22B.

[0042] The lip tip portion 22T does not have a parting line on the surface that comes into contact with the mounting panel 31. The lip tip portion 22T that does not have a parting line has a smooth surface 22TS that continues in the circumferential direction of the lip portion 22 on the surface that comes into contact with the mounting panel 31. The portion of the smooth surface 22TS that comes into contact with the lip base end portion 22B has a smooth convex surface that gently protrudes toward the main body seal portion 23 side of the lip portion 22 (see Figure 5).

[0043] The second parting lines 27 are arranged only at the lip base end 22B. The second parting lines 27 are arranged within the convex portions that are adjacent to the fastening portion 13 in the circumferential direction of the leg portion 12 among the convex portions that make up the concave-convex shape of the joint portion 25. Two second parting lines 27 are arranged per fastening portion 13 so as to sandwich the fastening portion 13 in the circumferential direction of the leg portion 12. The leg portion 12 does not have a stopper 18 between the fastening portion 13 and the second parting lines 27 in the circumferential direction of the leg portion 12. The set of two second parting lines 27 per fastening portion 13 is sandwiched between the stoppers 18 in the circumferential direction of the leg portion 12 (see FIG. 3).

[0044] The lip base end 22B, which has multiple second parting lines 27, allows for the use of a separate mold slide for molding the lip base end 22B. The separate mold for molding the second parting lines 27 is a mold for molding the fastening portion 13 in the leg portion 12. The protrusion amount of the convex portions that make up the uneven shape of the joint portion 25 is approximately equal to the minimum width of the lip base end 22B. The width of the lip base end 22B is the length of the lip base end 22B in a direction perpendicular to the circumferential direction of the lip portion 22.

[0045] As shown in Figure 5, the mounting panel 31 with the leg 12 inserted therein abuts the stopper 18 against the surface of the mounting panel 31. The slope of the fastening portion 13 passed through the insertion hole in the mounting panel 31 presses the back surface of the mounting panel 31 toward the stopper 18, thereby positioning the leg 12 on the mounting panel 31. The vehicle-mounted bracket with the leg 12 positioned thereon brings the lip tip 22T into contact with the surface of the mounting panel 31. The lip tip 22T in contact with the surface of the mounting panel 31 bends along the surface of the mounting panel 31 by the amount that it is pushed up against the surface of the mounting panel 31.

[0046] At this time, the relative position of the leg portion 12 with respect to the surface of the mounting panel 31 is determined in advance by the fastening portion 13 and the stopper 18. Furthermore, the relative position of the lip tip portion 22T with respect to the surface of the mounting panel 31 is determined in advance by the relative position of the stopper 18 with respect to the lip tip portion 22T. Then, the contact portion 22W, which is the portion of the lip tip portion 22T that comes into contact with the surface of the mounting panel 31, is determined in advance by the relative position of the stopper 18 with respect to the lip tip portion 22T. As a result, the lip tip portion 22T seals off water between the mounting panel 31 and the bracket main body 11. And, since the contact portion 22W of the lip portion 22 is predetermined by the relative position of the stopper 18 with respect to the lip tip portion 22T, the reproducibility of water sealing by the lip tip portion 22T is improved.

[0047] As shown in FIG. 5, the leg portion 12 has a pick-up portion 19. The pick-up portion 19 is provided over the entire circumferential direction of the leg portion 12. The pick-up portion 19 is a portion of the leg portion 12 that protrudes outward. The pick-up portion 19 has a slope that contacts the main body seal portion 23. The slope of the pick-up portion 19 is inclined with respect to the extension direction of the leg portion 12. The pick-up portion 19 extends to the lip base end portion 22B. In the first embodiment, the stopper 18 also extends to the lip base end portion 22B.

[0048] [Formation of lip portion 22] As shown in Figure 6, the vehicle-mounted bracket is manufactured by two-color molding using a hard material and a soft material. The molding die for the vehicle-mounted bracket includes a main body die 51, multiple lip base end dies 52, a main body seal part die 53, and one lip tip end die 54.

[0049] The main body mold 51 molds the inner surfaces of the leg portions 12 of the bracket main body 11 and the inner surface of the flange portion 11A. The lip base end mold 52 molds the outer surfaces of the leg portions 12 of the bracket main body 11 and the structure of the lip base end portion 22B that faces the mounting panel 31. The main body seal mold 53 molds the outer surfaces of the flange portion 11A of the bracket main body 11 and the outer surface of the main body seal portion 23. The lip tip mold 54 molds the entire lip tip portion 22T.

[0050] As shown in FIG. 7, when the vehicle-mounted bracket is demolded, first, the body seal mold 53 and the lip tip mold 54 are separated from the vehicle-mounted bracket along the extension direction of the leg 12. At this time, the lip tip 22T of the lip 22 is forcibly ejected from the lip tip mold 54. As a result, the lip tip 22T is molded without a parting line on the surface that contacts the mounting panel 31. A first parting line 26 is formed as the boundary between the lip tip 22T and the lip base end 22B. The portion of the smooth surface 22TS that contacts the lip base end 22B is formed as a smooth, convex surface that gently protrudes toward the body seal 23 side of the lip 22. The lip tip mold 54 that forcibly ejects the lip tip 22T bends the lip tip 22T while lifting it in the extension direction of the leg 12.

[0051] 8, to release the vehicle-mounted bracket from the mold, the multiple lip base end molds 52 are then separated from the vehicle-mounted bracket along the radial direction of the leg portion 12. As a result, the fastening portion 13 and the stopper 18 are molded by separate lip base end molds 52, along with the lip base end 22B having the second parting line 27 on the surface that contacts the mounting panel 31. In addition, the lip base end 22B is joined to the bracket main body 11 via the joint 25 having an uneven shape. Then, the lip portion 22 having the first parting line 26 and the second parting line 27 is molded together with the bracket main body 11.

[0052] [effect] As described above, according to the first embodiment, the following effects can be obtained. (1) The lip portion 22 of the seal portion 21 seals water between the flange portion 11A of the bracket main body 11 and the mounting panel 31. The first mounting hole formed in the main body seal portion 23 is positioned in the seal portion 21 so that the seal portion 21 seals water between the flange portion 11A and the camera cleaning nozzle 33. The second mounting hole formed in the main body seal portion 23 is positioned in the seal portion 21 so that the seal portion 21 seals water between the flange portion 11A and the in-vehicle camera 34.

[0053] In this way, the seal portion 21, which is formed integrally with the bracket main body 11, provides a watertight seal between the flange 11A and the mounting panel 31, and between the flange 11A and the on-board equipment. In particular, the seal portion 21 provides a watertight seal between the flange 11A and the on-board equipment, improving the sealing performance of the on-board bracket. Because a single seal portion 21 provides a watertight seal between the flange 11A and the mounting panel 31, and between the flange 11A and the on-board equipment, it is also possible to reduce the number of parts required for watertightness.

[0054] (2) When the seal portion 21 is formed integrally with the bracket main body 11, gaps are less likely to form between the bracket main body 11 and the seal portion 21. This improves the sealing performance between the bracket main body 11 and the seal portion 21. Furthermore, the process of attaching the vehicle-mounted device to the mounting panel 31 via the vehicle-mounted bracket also serves to seal water between the mounting panel 31 and the vehicle-mounted bracket, and between the vehicle-mounted bracket and the vehicle-mounted device. As a result, the vehicle-mounted bracket is easier to handle than when the bracket main body 11 is a separate member from the seal portion 21.

[0055] (3) When the seal portion 21 includes the first crimping portion 234 that protrudes so as to be crimped onto the camera cleaning nozzle 33, the first crimping portion 234 improves the watertightness between the camera cleaning nozzle 33 and the flange portion 11A.

[0056] (4) When the seal portion 21 includes the second crimping portion 235 that protrudes to be crimped onto the vehicle-mounted camera 34, the second crimping portion 235 improves the watertightness between the vehicle-mounted camera 34 and the flange portion 11A.

[0057] (5) When the lip portion 22 is positioned closer to the flange portion 11A than the fastening portion 13, the lip portion 22 is more likely to be pressed against the surface of the mounting panel 31 when the leg portion 12 is attached to the mounting panel 31. This improves the sealing performance of the lip portion 22 between the flange portion 11A and the mounting panel 31.

[0058] (6) When the surface of the lip tip portion 22T that comes into contact with the mounting panel 31 does not have a parting line, the sealing performance of the lip portion 22 between the flange portion 11A and the mounting panel 31 is improved compared to when the lip tip portion 22T has a parting line.

[0059] (7) When the boundary between the lip base end 22B and the lip tip portion 22T is the closed annular first parting line 26, the lip tip portion 22T can be demolded by force, such as by extracting the lip tip portion 22T from a mold that conforms to the outer shape of the lip tip portion 22T.

[0060] (8) When the lip base end 22B has the second parting line 27, the split mold can slide along the outer shape of the lip base end 22B during mold release of the lip base end 22B. This reduces the design load on the lip tip end 22T, which requires forced removal.

[0061] (9) When the joint 25 has an uneven shape that is repeated in the circumferential direction of the flange 11A, the area of ​​the joint 25 that comes into contact with the bracket main body 11 increases. This increases the strength with which the lip portion 22 is joined to the bracket main body 11.

[0062] (Second embodiment) The vehicle-mounted bracket according to the second embodiment will be described with reference to Fig. 9. Description of the configuration common to the vehicle-mounted bracket according to the first embodiment and the vehicle-mounted bracket according to the second embodiment will be omitted.

[0063] The structures of the leg portion 12 and the lip portion 22 may be modified so that the tip of the picking portion 19 is positioned outward from the tip of the stopper 18 and so that a vertical step is provided between the lower surface of the picking portion 19 and the lower surface of the stopper 18. That is, unlike the first embodiment, the stopper 18 does not extend to the lip base end portion 22B. In other words, because the picking portion 19 extends to the lip base end portion 22B while the stopper 18 does not extend to the lip base end portion 22B, the tip of the picking portion 19 is positioned outward from the tip of the stopper 18.

[0064] According to the second embodiment, the following effects can be obtained. Because the lip base end 22B is separated outward from the stopper 18, the boundary between the lip base end 22B and the leg portion 12 is determined by the pick-up portion 19 over the entire circumferential direction, and as a result, the base end of the bending range in the lip portion 22 is determined over the entire circumferential direction by the pick-up portion 19. Furthermore, when the mounting panel 31 abuts against the stopper 18, the distance in the up-and-down direction between the mounting panel 31 and the lip base end 22B is constant over the entire circumferential direction. Therefore, the bending stress acting on the lip base end 22B is prevented from varying over the circumferential direction, the surface pressure acting on the lip tip portion 22T is made uniform over the circumferential direction, and partial reductions in surface pressure over the circumferential direction are prevented.

[0065] [Example of change] The above first and second embodiments can also be modified and implemented as follows. The joint 25 may have a repeated uneven shape not only in the circumferential direction of the flange 11A but also in the extension direction of the leg 12 or in a direction intersecting these directions. The size of the convex portions constituting the uneven shape of the joint 25 and the concave portions arranged on the outer peripheral surface of the leg 12 may be smaller or larger than that of the fastening portion 13.

[0066] The outer peripheral surface of the leg portion 12 may be omitted from the recesses for imparting an uneven shape to the joint portion 25. In this case, the joint portion 25 may be omitted from the uneven shape and have a band shape extending in the circumferential direction of the leg portion 12. Even with this configuration, the effects equivalent to those of (1) to (8) above can be obtained.

[0067] The lip portion 22 may omit the first parting line 26. In this case, the lip tip portion 22T may have a plurality of parting lines aligned in the circumferential direction of the flange portion 11A, similar to the lip base end portion 22B. Even if the lip tip portion 22T has a parting line, the same effects as those of (1) to (6) and (9) above can be obtained.

[0068] The flange 11A may have a bowl shape that covers part of the outer peripheral surface of the leg 12. In this case, the lip 22 that extends around the flange 11A may be disposed on the opposite side of the flange 11A from the fastening portion 13 in the extension direction of the leg 12. As described above, the portion of the mounting panel 31 that the lip 22 contacts is different from the portion of the mounting panel 31 that the fastening portion 13 fastens. Therefore, the relative position of the lip 22 with respect to the fastening portion 13 in the extension direction of the leg 12 can be changed as appropriate depending on the shape of the mounting panel 31. Note that if the mounting panel 31 has a flat shape around the hole into which the leg 12 is inserted, the lip 22 may be disposed closer to the flange 11A than the fastening portion 13. This configuration provides an effect similar to that described in (5) above.

[0069] The first crimping portion 234 may not protrude, and the second crimping portion 235 may not protrude. In this case, the main body seal portion 23 may have a flat shape, or may have a recess around the first mounting hole that is crimped to the camera cleaning nozzle 33, or may have a recess around the second mounting hole that is crimped to the in-vehicle camera 34. The main body seal portion 23 only needs to have a structure that contacts the in-vehicle device attached to the bracket main body 11 so as to seal off water between the in-vehicle device and the flange portion 11A.

[0070] The watertight portion is not limited to the lip portion 22 having the lip base end portion 22B and the lip tip end portion 22T, but may also be a ring-shaped body with a circular cross section that is arranged around the flange portion 11A and has watertightness and elasticity to seal the gap between the flange portion 11A and the mounting panel 31, or a strip-shaped body with a rectangular cross section.

[0071] The mounting hole may expose the flange 11A other than the mounting portion through the mounting hole, thereby assisting in mounting the in-vehicle device to the mounting portion, without exposing the mounting portion from the seal portion 21. The portion of the flange 11A exposed through the mounting hole may function to position the in-vehicle device or as a path for passing the wiring of the in-vehicle device. [Explanation of symbols]
