Description

[Technical Field]

[0001] The present invention relates to an exterior part for a vehicle. [Background technology]

[0002] Patent Document 1 describes an electromagnetic wave transparent cover that is placed in front of a radar device. This electromagnetic wave transparent cover includes a resin cover base material, a heater film that is placed adjacent to the rear surface of the cover base material, and a connector that is joined to the heater film.

[0003] The cover base material is integrally formed with the heater film and the connector by inserting the heater film and the connector. The connector has a resin connector housing to which a connector of a device (hereinafter referred to as a mating connector) for supplying power to the heater film is connected.

[0004] In such an electromagnetic wave transmission cover, a portion of the connector housing is embedded in the cover base material, thereby supporting the connector on the cover base material. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-67011 Summary of the Invention [Problem to be solved by the invention]

[0006] In conventional vehicle exterior accessories having such heater films, when a mating connector is connected to a connector housing, a load is applied to the connector housing, for example, along the axial or circumferential direction of the connector housing. At this time, stress caused by the load is concentrated at the interface between the connector housing and the cover base material. As a result, the connector may peel off from the cover base material. [Means for solving the problem]

[0007] Various aspects of vehicle exterior accessories for solving the above problems will be described below. [Embodiment 1] A vehicle exterior accessory comprising: a resin sheet base material; a heater portion held by the sheet base material and having a heater wire that generates heat when electricity is passed through it; a resin connector portion joined to the sheet base material; and a resin base material into which the heater portion and the connector portion are inserted and molded integrally with the heater portion and the connector portion, wherein the connector portion has a cylindrical housing that is open at one end and embedded at the other end in the base material, and when the direction along the axis of the housing is defined as the axial direction of the housing, the portion of the housing that is embedded in the base material is provided with a protrusion that protrudes from the outer peripheral surface of the housing and has one and the other end faces in the axial direction joined to the base material.

[0008] According to the above configuration, a protrusion is provided on the portion of the housing that is embedded in the substrate (hereinafter referred to as the embedded portion). Furthermore, both end faces of the protrusion in the axial direction are joined to the substrate. Therefore, the stress acting in the axial direction on the interface between the embedded portion and the substrate is dispersed by providing the protrusion. This makes it difficult for the housing to peel off from the substrate when a load is applied to the housing along the axial direction. Therefore, it is possible to prevent the connector portion from peeling off from the substrate.

[0009] [Embodiment 2] When the circumferential direction of the housing is simply defined as the circumferential direction, the protrusion is a flange portion that extends over the entire housing in the circumferential direction.

[0010] With this configuration, the area of the interface between the base material and both end faces of the protrusion in the axial direction of the housing is increased compared to when the protrusion is provided on a portion of the housing in the circumferential direction. This allows the stress acting in the axial direction to be more dispersed at the interface between the embedded portion and the base material. This further reduces the risk of the connector portion peeling off from the base material.

[0011] [Embodiment 3] The vehicle exterior part according to [Embodiment 2], wherein the flange portion has a flange portion main body extending over the entire housing in the circumferential direction, and an uneven portion provided as a recess or protrusion on a portion of the flange portion main body, and the end face of the uneven portion in the circumferential direction is joined to the base material.

[0012] When a mating connector is connected to a housing, if stress acts in the circumferential direction on the interface between the flange portion of the housing and the substrate, the flange portion may peel off from the substrate. According to the above configuration, the flange portion is provided with the uneven portion. Therefore, the stress acting in the circumferential direction is dispersed by the circumferential interface between the uneven portion and the substrate. This makes it difficult for the flange portion to peel off from the substrate. Therefore, peeling of the connector from the substrate can be further suppressed.

[0013] [Aspect 4] The vehicle exterior accessory according to any one of [Aspect 1] to [Aspect 3], further comprising a terminal portion electrically connected to the heater wire, the connector portion being integrally connected to the other end of the housing and having a terminal holding portion that holds the terminal portion, the terminal holding portion being bonded to the base material.

[0014] When a mating connector is connected to the housing, if stress due to a load applied to the housing is concentrated at the interface between the terminal holder and the substrate, the terminal holder may peel off from the substrate. In this case, the stress acts on the terminal and heater wire via the terminal holder, which may cause the heater wire to break or cracks to form at the connection between the heater wire and the terminal.

[0015] In this regard, with the above-described configuration, stress due to a load applied to the housing is dispersed by the protruding portion of the housing, making it difficult for the terminal holder to peel off from the substrate. In other words, the terminal holder can be maintained in an optimal state supported by the substrate. This makes it difficult for the stress to act on the terminal and heater wire via the terminal holder. This prevents breakage of the heater wire and cracks from occurring at the connection between the heater wire and the terminal.

[0016] [Embodiment 5] The vehicle exterior part according to [Embodiment 4], wherein the terminal holding portion has a rib that protrudes toward the base material and is embedded in the base material. According to the above configuration, the ribs of the terminal holder are embedded in the substrate. Therefore, even if stress due to a load applied to the housing acts on the interface between the terminal holder and the substrate, the stress is dispersed at the interface between the ribs and the substrate. This makes it difficult for the terminal holder to peel off from the substrate. As a result, the terminal holder of the connector can be more suitably maintained in a state where it is supported by the substrate. Therefore, peeling of the connector from the substrate can be further suppressed. [Effects of the Invention]

[0017] According to the present invention, it is possible to prevent the connector from peeling off from the substrate. [Brief explanation of the drawings]

[0019] An embodiment of a vehicle exterior accessory will be described below with reference to Figures 1 to 7. In this embodiment, the present invention is embodied as an electromagnetic wave transmission cover 12 provided at the front of a vehicle 10.

[0020] In the following description, the fore-and-aft direction of the vehicle 10 will be simply referred to as the fore-and-aft direction L, and the front and rear in the fore-and-aft direction L will be simply referred to as the front and rear. The width direction of the vehicle 10 will be simply referred to as the vehicle width direction W. The up-and-down direction of the vehicle 10 when the vehicle 10 is positioned on a horizontal plane will be simply referred to as the up-and-down direction H, and the upper and lower sides in the up-and-down direction H will be simply referred to as the upper and lower sides.

[0021] 1 to 3, a radar device 11 is disposed at the front of a vehicle 10 as an on-board sensor that transmits and receives electromagnetic waves to detect objects outside the vehicle. The radar device 11 transmits electromagnetic waves having a wavelength of 1 mm to 10 mm and a frequency of 30 GHz to 300 GHz, so-called millimeter waves. In this embodiment, the transmission direction of the millimeter waves from the radar device 11 coincides with the longitudinal direction L.

[0022] In front of the radar device 11, an electromagnetic wave transparent cover 12 (hereinafter simply referred to as the cover 12) is arranged. The cover 12 constitutes part of the outer shell of the vehicle 10 at the front of the vehicle 10, and includes a base material 20, a heater portion 30, a pair of terminal portions 40, and a connector portion 50.

[0023] Each component will be described in detail below. <Base material 20> As shown in FIG. 3, the base material 20 is made of a resin material and has millimeter wave transparency.

[0024] Examples of resin materials for forming the substrate 20 include polyolefin resins such as polyethylene (PE) and polypropylene (PP), acrylic resins such as acrylonitrile-butadiene-styrene copolymer (ABS) resin, acrylonitrile-ethylene-styrene copolymer (AES) resin, acrylonitrile-styrene-acrylate copolymer (ASA) resin, and polymethyl methacrylate resin (PMMA), and thermoplastic resins such as polycarbonate (PC). Two or more of the above resin materials may also be used in combination. In this embodiment, the substrate 20 is formed from ABS resin.

[0025] As shown in Figures 1 to 3, the base material 20 has a cover body 21, an extension 22 that partially extends from the edge 21e of the cover body 21, and a frame 23 that extends along the edges 21e, 22e of the cover body 21 and the extension 22.

[0026] (Cover body 21) The cover body 21 is a main component of the cover 12, and is formed in the shape of a rectangular plate having a pair of long sides aligned in the up-down direction H and a pair of short sides aligned in the vehicle width direction W in a front view (see FIG. 1). In this embodiment, the cover body 21 is disposed at the frontmost position of the cover 12 so as to be perpendicular to the front-to-rear direction L (see FIG. 3).

[0027] (Extending part 22) The extension portion 22 is bent from the edge portion 21e of the cover portion main body 21 and extends rearward. The extending portion 22 is inclined with respect to the front-rear direction L. Specifically, the extending portion 22 is inclined so as to slope downward as it extends rearward (see FIG. 3).

[0028] For ease of explanation, one side (front and downward side) in the thickness direction of the extension portion 22 will be referred to as the front, and the other side (rear and upward side) will be referred to as the rear. (Frame 23) As shown in FIGS. 1 to 3, the frame portion 23 is provided over the entire edge portions 21e, 22e of the cover main body 21 and the extension portion 22. As shown in FIGS.

[0029] The portion of the frame portion 23 surrounding the extension portion 22 is composed of a first wall portion 24 connected to the rear end of the extension portion 22 and a pair of second wall portions 25 connected to both ends of the extension portion 22 in the vehicle width direction W.

[0030] <Heater section 30> 1 to 3, the heater section 30 heats the cover section main body 21, and includes a sheet base material 31 joined to the rear surface 20b of the base material 20, and a heater wire 35 that generates heat when energized. The heater section 30 as a whole is millimeter wave transparent.

[0031] (sheet substrate 31) 3, the sheet substrate 31 is formed into a sheet shape from a resin material. Examples of resin materials that can be used to form the sheet substrate 31 include the same resin materials as those exemplified for the substrate 20. From the viewpoint of adhesion to the substrate 20, it is preferable that the resin material for the sheet substrate 31 be the same as that for the substrate 20. In this embodiment, the sheet substrate 31 is formed from ABS resin.

[0032] A main portion of the sheet base material 31 is joined to the cover body 21. On the other hand, a part of the sheet base material 31 (hereinafter referred to as the sheet extension portion 32) extends along the extension portion 22. Two openings 33 and 34 are formed in the sheet extension portion 32. The openings 33 and 34 are arranged at an interval from each other in the direction in which the sheet extension portion 32 extends.

[0033] (heater wire 35) The heater wire 35 is formed of a resistance wire, that is, a conductive wire such as a nichrome wire, which is generally considered to have a high electrical resistance.

[0034] 3, the heater wire 35 is embedded in the front surface 31f of the sheet substrate 31 and held by the sheet substrate 31. The heater wire 35 is wired in a predetermined wiring pattern on the front surface 31f. In this embodiment, as shown in FIG. 1, the heater wire 35 is wired in a wiring pattern having a plurality of straight portions 35a extending parallel to one another and a plurality of connecting portions 35b connecting ends of adjacent straight portions 35a.

[0035] 2 and 3, both end portions 36 of the heater wire 35 in the extending direction are wired to the seat extending portion 32. The both end portions 36 are spaced apart in the vehicle width direction W and extend parallel to each other along the extending portion 22.

[0036] <Terminal section 40> 2 and 3, the pair of terminal portions 40 are formed in the same shape and made of a conductive material such as metal. Therefore, hereinafter, only one of the terminal portions 40 will be described, and a description of the other terminal portion 40 will be omitted.

[0037] The terminal portion 40 has a first connection portion 41 extending along the extension portion 22, and a second connection portion 43 bending from the rear end of the first connection portion 41 and extending rearward along the front-rear direction L (see FIG. 3).

[0038] The first connection portion 41 is disposed in front of the sheet extension portion 32. A front portion 41a of the first connection portion 41 is electrically connected to the end portion 36 of the heater wire 35. The front portion 41a and the end portion 36 are joined from the rear using a well-known method, such as fusing, soldering, or pressure welding such as crimping. The joint between the front portion 41a and the end portion 36 is exposed to the rear through the opening 33 of the sheet extension portion 32.

[0039] A communication hole 42 that communicates with the opening 34 is provided in the rear portion 41b of the first connecting portion 41 at a position corresponding to the opening 34. A connector of the device 13 (hereinafter referred to as a mating connector 14) for supplying power to the heater wire 35 is electrically connected to the second connection portion 43 (see FIG. 3).

[0040] The terminal portion 40 is formed, for example, by punching a metal plate into a predetermined shape and then bending the same. <Connector part 50> 3 to 5, the connector portion 50 is made of an electrically insulating resin material. In this embodiment, the connector portion 50 is made of AES resin.

[0041] The connector section 50 has a terminal holding section 51 that fixes the terminal section 40 to the heater section 30, and a housing 59 into which the mating connector 14 is inserted and removed. (Terminal holding part 51) The terminal holding portion 51 holds the terminal portion 40 and is joined to the sheet extension portion 32 of the sheet base material 31 .

[0042] The terminal holding portion 51 has a front holding portion 52 and a rear holding portion 54 that is disposed on the opposite side of the front holding portion 52 with respect to the sheet extension portion 32 and the terminal portion 40 . The front holding portion 52 is in the form of a plate that extends along the extension portion 22 and in the vehicle width direction W.

[0043] The rear portions 41b of the pair of first connecting portions 41 are embedded in the rear surface 52b of the front holding portion 52. 3 and 4, a rear surface 52b of the front holding portion 52 is formed with a plurality of protrusions 53 to be inserted into the pair of communication holes 42. In this embodiment, two protrusions 53 are inserted into one communication hole 42 and engaged with the inner surface of the communication hole 42. This prevents the terminal portion 40 from being misaligned with the terminal holding portion 51.

[0044] The portion of the rear surface 52b of the front holding portion 52 that does not overlap with the pair of first connecting portions 41 is joined to the front surface 32f of the seat extension portion 32. 2 and 3, the front holding portion 52, the front portions 41a of the pair of first connection portions 41, and the portions of the front surface 32f of the seat extension portion 32 that do not overlap with the front holding portion 52 and the pair of first connection portions 41 are all covered from the front by the extension portion 22. Here, the front holding portion 52 and the seat extension portion 32 are each joined to the extension portion 22 at their interfaces.

[0045] As shown in FIGS. 3 to 6, the rear holding portion 54 is in the form of a plate that extends along the extending portion 22 and in the vehicle width direction W. A surface of the front surface 54f of the rear retaining portion 54 corresponding to the central portion 54A in the vehicle width direction W is joined to the rear surface 32b of the seat extension portion 32 (see FIG. 3). Further, a surface of the front surface 54f corresponding to portions extending from the central portion 54A to both sides in the vehicle width direction W (hereinafter referred to as side portions 54B) is joined to the extension portion 22 (see FIG. 6).

[0046] As shown in FIGS. 3 and 4, the rear holding portion 54 is formed with two windows 55 and 56 that penetrate the rear holding portion 54 in the plate thickness direction. The window portion 55 surrounds the pair of openings 33 collectively, and exposes the joint between the end 36 of the heater wire 35 and the front portion 41a of the first connection portion 41 to the rear.

[0047] The window portion 56 surrounds the pair of openings 34 collectively. A water-stopping member (not shown) is attached to the windows 55 and 56 to prevent water from entering the interior of the windows 55 and 56. Such a water-stopping member is formed by filling the windows 55 and 56 with a resin material, for example.

[0048] As shown in FIG. 2, the pair of side portions 54B extend from the central portion 54A to the pair of second wall portions 25 and are joined to the inner surfaces of the second wall portions 25. As shown in FIGS. 4 to 6, the rear holding portion 54 has a first rib 57 protruding from the rear surface 54b and a second rib 58 protruding from the front surface 54f.

[0049] The first ribs 57 are provided adjacent to each other on both sides of the window portions 55, 56 in the vehicle width direction W (see FIG. 4). The second ribs 58 are formed one on each side opposite the pair of first ribs 57 in the plate thickness direction of the rear retaining portion 54. The pair of second ribs 58 are embedded in the extending portion 22 (see FIG. 6). More specifically, both end faces 58a of the pair of second ribs 58 in the front-rear direction L and both end faces 58b of the pair of second ribs 58 in the vehicle width direction W are joined to the extending portion 22.

[0050] (Housing 59) 2 to 5, the housing 59 is cylindrical and has a recess 59a that opens rearward, and is integrally connected to the rear end of the terminal holding portion 51. When the mating connector 14 is inserted into the recess 59a, the device 13 is electrically connected to the second connection portion 43 of the terminal portion 40 extending into the recess 59a, and ultimately to the heater portion 30 (see FIG. 3). In this embodiment, the axial direction of the housing 59 coincides with the front-rear direction L.

[0051] 2, 3, and 7, a portion of the housing 59 including its front end is embedded in the first wall portion 24. Hereinafter, the portion of the housing 59 embedded in the first wall portion 24 will be described as an embedded portion 60.

[0052] As shown in FIGS. 2 to 7, the embedded portion 60 is provided with a flange portion 61 that protrudes from the outer peripheral surface 59b of the housing 59. The flange portion 61 has a flange portion main body 62 that extends over the entire housing 59 in the circumferential direction C of the housing 59 , and a protrusion 63 that is provided on the flange portion main body 62 in a protruding manner.

[0053] As shown in FIGS. 2, 3, and 7, both end surfaces of the flange portion main body 62 in the front-rear direction L (hereinafter referred to as the front surface 62f and the rear surface 62b) are joined to the first wall portion 24. Also, a radial end surface 62a of the flange portion main body 62 is joined to the first wall portion 24 (see FIG. 3). The rear ends of the pair of first ribs 57 and the rear ends of the pair of side portions 54B are connected to the flange portion main body 62. This reinforces the flange portion main body 62. The rear ends of the pair of first ribs 57 and the rear ends of the pair of side portions 54B each form a part of the embedded portion 60. That is, the end surfaces in the circumferential direction C of the rear ends of the pair of first ribs 57 and the rear ends of the pair of side portions 54B are joined to the first wall portion 24.

[0054] The protrusions 63 protrude from the front surface 62f of the flange portion main body 62. In the present embodiment, two protrusions 63 are provided between the pair of first ribs 57. Both end surfaces 63a of each protrusion 63 in the circumferential direction C are joined to the first wall portion 24.

[0055] The cover 12 of the above-described embodiment is formed integrally, for example, by joining the terminal portion 40 and the connector portion 50 to the heater portion 30, and then inserting the heater portion 30, the terminal portion 40, and the connector portion 50 into a mold and insert molding the base material 20.

[0056] <Operation of this embodiment> Next, the operation of this embodiment will be described. An embedded portion 60 of the housing 59 that is embedded in the first wall portion 24 of the base material 20 is provided with a flange portion 61 as a protruding portion. A front surface 62f and a rear surface 62b of the flange portion main body 62 in the front-rear direction L are joined to the first wall portion 24. Therefore, the stress acting in the front-rear direction L on the interface between the embedded portion 60 and the base material 20 is dispersed by providing the flange portion 61. This makes it difficult for the housing 59 to peel off from the base material 20 when a load is applied to the housing 59 in the front-rear direction L.

[0057] <Effects of this embodiment> Next, the effects of this embodiment will be described. (1) The cover 12 includes a resin sheet base material 31, a heater section 30 having a heater wire 35, a resin connector section 50 joined to the sheet base material 31, and a resin base material 20 into which the heater section 30 and the connector section 50 are inserted and integrally molded with the heater section 30 and the connector section 50. The connector section 50 has a cylindrical housing 59 having one end open and the other end embedded in the first wall section 24 of the base material 20. The embedded section 60 is provided with a flange section 61 as a protruding section that protrudes from an outer peripheral surface 59b of the housing 59 and has a front surface 62f and a rear surface 62b in the front-rear direction L joined to the first wall section 24.

[0058] This configuration provides the above-mentioned effects, and therefore, the connector portion 50 can be prevented from peeling off from the base material 20. (2) The protrusion is a flange portion 61 having a flange portion main body 62 that extends over the entire housing 59 in the circumferential direction C.

[0059] With this configuration, the area of the interface between the front surface 62f and the rear surface 62b of the flange portion main body 62 and the first wall portion 24 of the base material 20 in the front-rear direction L is increased compared to when a protrusion is provided on a portion of the housing 59 in the circumferential direction C. This allows the stress acting on the interface between the embedded portion 60 and the base material 20 in the front-rear direction L to be more dispersed. This further reduces the risk of the connector portion 50 peeling off from the base material 20.

[0060] (3) The flange portion 61 has a protrusion 63 as an uneven portion protruding from the front surface 62f of the flange portion main body 62. Both end surfaces 63a of the protrusion 63 in the circumferential direction C are joined to the first wall portion 24 of the base material 20.

[0061] When the mating connector 14 is connected to the recess 59a of the housing 59, if stress acts along the circumferential direction C on the interface between the flange portion 61 of the housing 59 and the base material 20, there is a risk that the flange portion 61 will peel off from the base material 20. Here, according to the above configuration, the flange portion 61 is provided with the protrusion 63. Therefore, the interface in the circumferential direction C between the protrusion 63 and the first wall portion 24 of the base material 20 distributes the stress acting in the circumferential direction C. This makes it difficult for the flange portion 61 to peel off from the first wall portion 24 of the base material 20. Therefore, peeling of the connector portion 50 from the base material 20 can be further suppressed.

[0062] (4) The cover 12 further includes a terminal portion 40 that is electrically connected to the heater wire 35. The connector portion 50 is integrally connected to the front end of the housing 59 and has a terminal holding portion 51 that holds the terminal portion 40. The terminal holding portion 51 is joined to the extension portion 22 of the base material 20.

[0063] When the mating connector 14 is connected to the housing 59, if stress due to a load applied to the housing 59 is concentrated at the interface between the terminal holding portion 51 and the substrate 20, the terminal holding portion 51 may peel off from the substrate 20. In this case, the stress acts on the first connecting portion 41 of the terminal portion 40 and the heater wire 35 via the terminal holding portion 51, which may cause a break in the heater wire 35 or a crack in the connection between the end portion 36 of the heater wire 35 and the front portion 41a of the first connecting portion 41.

[0064] In this regard, with the above-described configuration, stress due to a load applied to the housing 59 is dispersed by the flange portion 61 of the housing 59, making it difficult for the terminal holding portion 51 to peel off from the base material 20. In other words, the terminal holding portion 51 can be maintained in an appropriate state supported by the base material 20. This makes it difficult for the stress to act on the first connection portion 41 of the terminal portion 40 and the heater wire 35 via the terminal holding portion 51. This makes it possible to prevent breakage of the heater wire 35 and cracks from occurring in the connection portion between the end portion 36 of the heater wire 35 and the front portion 41a of the first connection portion 41.

[0065] (5) The rear holding portion 54 of the terminal holding portion 51 has the second rib 58 that protrudes toward the extension portion 22 of the base material 20 and is embedded in the extension portion 22 . According to this configuration, the second rib 58 of the rear holding portion 54 is embedded in the extension portion 22. Therefore, even if stress due to a load applied to the housing 59 acts on the interface between the terminal holding portion 51 and the base material 20, the stress is dispersed at the interface between the second rib 58 and the extension portion 22. This makes it difficult for the terminal holding portion 51 to peel off from the base material 20. As a result, the terminal holding portion 51 of the connector portion 50 can be more suitably maintained in a state where it is supported by the base material 20. Therefore, peeling of the connector portion 50 from the base material 20 can be further suppressed.

[0066] (6) The rear ends of the pair of first ribs 57 and the end faces in the circumferential direction C of the rear ends of the pair of side portions 54B are joined to the first wall portion 24. According to this configuration, the stress acting along the circumferential direction C is dispersed by the interfaces in the circumferential direction C between the pair of first ribs 57 and the pair of side portions 54B and the first wall portion 24 of the base material 20. This makes it even more difficult for the flange portion 61 to peel off from the first wall portion 24 of the base material 20.

[0067] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined and implemented within the scope of technical compatibility.

[0068] The number and arrangement of the second ribs 58 are not limited to those exemplified in this embodiment. For example, three or more second ribs 58 may be provided on the terminal holding portion 51, or only one second rib 58 may be provided. Also, the second rib 58 may be provided on the front holding portion 52.

[0069] The second rib 58 may be omitted. The first rib 57 may be omitted. The shape of the terminal holder 51 is not limited to that exemplified in this embodiment. For example, the rear ends of the pair of side portions 54B do not have to be connected to the flange main body 62 and embedded in the first wall portion 24.
