Description

[Technical Field]

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

[0002] Patent Document 1 describes a millimeter-wave transparent cover for a vehicle that is placed in front of a millimeter-wave radar device. This millimeter-wave transparent cover includes a cover base material, a heater film, and a connector. The cover base material forms the front surface of the millimeter-wave transparent cover.

[0003] The heater film is disposed adjacent to the rear portion of the cover substrate. The heater film includes a film substrate and a heat generating portion provided on the front surface of the film substrate and generating heat when energized. Both ends of the heat generating portion protrude from the film substrate.

[0004] The connector includes a connector housing and a pair of terminals assembled to the connector housing. The terminals include a rectangular rod-shaped base and a plate-shaped extension that bends and extends from the front end of the base. The base is inserted into the connector housing. The extension is soldered to a portion of the heat generating part that protrudes from the film substrate. The joint between the extension and the heat generating part is covered with a cover substrate via the solder. [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] However, in conventional vehicle exterior accessories including such millimeter wave transmitting covers, the connector housing, which is relatively large, protrudes rearward from the cover base, which poses a problem of the vehicle exterior accessory being large in size. [Means for solving the problem]

[0007] Various aspects of vehicle exterior accessories for solving the above problems will be described below. [Aspect 1] A vehicle exterior accessory comprising a resin base material, a heater sheet that heats the base material, and a wire harness that supplies power to the heater sheet, wherein the heater sheet comprises a resin sheet base material that is laminated on the inner surface of the base material and forms part of the inner surface of the vehicle exterior accessory, a heater wire that is disposed between the sheet base material and generates heat when electricity is passed through it, and a conductive plate material formed of a conductive material, wherein the sheet base material has a through-hole that penetrates the sheet base material in the thickness direction and through which the conductive plate material is inserted, and an end of the heater wire is electrically connected to the outer surface of the conductive plate material, and the electric wires of the wire harness are electrically connected to the inner surface of the conductive plate material.

[0008] According to the above configuration, the heater wire generates heat when power is supplied from the wire harness via the conductive plate. Therefore, compared to conventional vehicle exterior accessories that use a connector as a means for supplying power to the heater wire, the vehicle exterior accessory does not need to be provided with a relatively large connector housing, and therefore the vehicle exterior accessory is less likely to become large in size. Therefore, the vehicle exterior accessory can be made smaller in size.

[0009] Furthermore, when the heater wire and the wire harness are directly joined, stress acting on the wire harness tends to concentrate at the connection point between the heater wire and the wire harness. In this case, there is a risk of the heater wire, which has a smaller diameter than the wire harness, breaking. In this regard, with the above-described configuration, the heater wire and the wire harness are electrically connected via the conductive plate. This makes it difficult for the above-described stress to act on the heater wire. Therefore, breakage of the heater wire can be suppressed.

[0010] Furthermore, with the above configuration, since a flexible wire harness can be used, there are fewer restrictions on the arrangement of the end of the heater wire and the conductive plate material, thereby improving the degree of freedom in designing vehicle exterior accessories.

[0011] [Aspect 2] The vehicle exterior accessory according to [Aspect 1], wherein the outer surface of the sheet substrate is bonded to the inner surface of the substrate with the heater wire sandwiched therebetween. When laminating a sheet substrate of a heater sheet onto a substrate, it is possible to injection mold the substrate using the heater sheet as an insert member. However, this method presents the following problem. Specifically, the heater wire disposed between the sheet substrate and the substrate comes into close contact with the inner surface of the substrate when the substrate is molded. In this case, when the molten resin is cooled and solidified during the injection molding process, the portion of the substrate that is in close contact with the heater wire cools and solidifies faster than other portions due to heat absorption by the heater wire. This results in a difference in the amount of thermal shrinkage between the portion of the substrate that is in close contact with the heater wire and the other portions. As a result, there is a risk of sink marks occurring on the outer surface of the substrate at positions corresponding to the portions of the substrate that are in close contact with the heater wire.

[0012] In this regard, according to the above-described configuration, the vehicle exterior part is manufactured by bonding the sheet substrate, which is molded separately from the substrate, to the inner surface of the substrate with the heater wire sandwiched therebetween. Therefore, the sink marks described above do not occur on the outer surface of the substrate due to insert molding. Therefore, it is possible to prevent the appearance of the substrate, and therefore the appearance of the vehicle exterior part, from being impaired.

[0013] [Aspect 3] The vehicle exterior accessory according to [Aspect 1] or [Aspect 2], further comprising a sealant formed by applying a resin material to the connection points between the inner surface of the conductive plate and the electric wires of the wire harness, the sealant sealing the connection points, the sealant constituting a part of the inner surface of the vehicle exterior accessory together with the sheet base material.

[0014] According to the above configuration, the sealing material that constitutes a part of the inner surface of the vehicle exterior part is formed into a thin film, which prevents the sealing material, and therefore the vehicle exterior part, from increasing in size in the thickness direction compared to when the sealing material is formed by injection molding a resin material, for example. [Effects of the Invention]

[0015] According to the present invention, the size of a vehicle exterior accessory can be reduced. [Brief explanation of the drawings]

[0017] An embodiment of a vehicle exterior accessory will be described below with reference to Figures 1 to 6. In this embodiment, the present invention is embodied as an electromagnetic wave transparent cover 12 attached to the front of a vehicle 10. In the following description, the fore-and-aft direction of the vehicle 10 will be simply referred to as the fore-and-aft direction, and the front and rear in the fore-and-aft direction will be simply referred to as the front and rear.

[0018] <Electromagnetic wave transparent cover 12> As shown in Figures 1 and 2, a radar device 11 and an electromagnetic wave transparent cover 12 are provided at the front of a vehicle 10. The radar device 11 is 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 front-to-rear direction.

[0019] The electromagnetic wave transparent cover 12 is disposed in front of the radar device 11. The electromagnetic wave transparent cover 12 is disposed in a position perpendicular to the front-rear direction. Here, in this embodiment, the front-rear direction of the electromagnetic wave transparent cover 12 corresponds to the outside-inside direction of the vehicle 10. Furthermore, the "front" and "forward" of each part of the electromagnetic wave transparent cover 12 correspond to the "outside" and "outward" of the vehicle 10, and the "rear" and "rearward" of each part correspond to the "inside" and "inward" of the vehicle 10.

[0020] The electromagnetic wave transmission cover 12 includes a main body 12A having a cover substrate 20 and a heater sheet 30, a wire harness 50, and a sealing material . Each component will be described in detail below.

[0021] (Cover substrate 20) As shown in FIGS. 1 and 2, the cover substrate 20 is a component that constitutes part of the outer shell of the vehicle 10 at the front of the vehicle 10. The cover substrate 20 corresponds to the substrate according to the present invention. The cover substrate 20 is a flat plate having a thickness in the front-to-rear direction, and has a front surface 20a and a rear surface 20b. The front surface 20a of the cover substrate 20 constitutes the front surface of the electromagnetic wave transmission cover 12, i.e., the design surface of the electromagnetic wave transmission cover 12. From the viewpoint of improving design, it is preferable that a colored layer (not shown) formed of a resin material having a dispersed colorant or a paint containing a color pigment is provided on the front surface 20a. In this case, for example, by matching the color of the colored layer with the color of the colored layer of the surrounding exterior members, a unified appearance can be achieved at the front of the vehicle 10.

[0022] The cover substrate 20 is made of a resin material that is electromagnetically transparent (millimeter wave transparent). Examples of resin materials that can be used to form the cover substrate 20 include polypropylene (PP), polycarbonate (PC), acrylic resins such as polymethyl methacrylate resin (PMMA), acrylonitrile-butadiene-styrene copolymer (ABS) resin, acrylonitrile-ethylene-styrene copolymer (AES) resin, and acrylonitrile-styrene-acrylate copolymer (ASA) resin. Two or more of the above resin materials may also be used in combination. In this embodiment, the cover substrate 20 is made of PP.

[0023] (Heater Sheet 30) As shown in FIGS. 1 and 2, the heater sheet 30 includes a sheet substrate 31 and a conductive portion 33. The sheet substrate 31 is a thin plate having a thickness in the front-rear direction and has a front surface 31a and a rear surface 31b. That is, the front-rear direction in this embodiment corresponds to the thickness direction of the sheet substrate in the present invention. The sheet substrate 31 is laminated on the rear surface 20b of the cover substrate 20. Specifically, the front surface 31a of the sheet substrate 31 is adhered to the rear surface 20b of the cover substrate 20 via an adhesive layer 40 (see FIG. 2). Any adhesive can be used to form the adhesive layer 40 as long as it does not significantly reduce the electromagnetic wave transparency (millimeter wave transparency) of the electromagnetic wave transmission cover 12. In this embodiment, an optically clear resin (OCR) is used as the adhesive to form the adhesive layer 40. The rear surface 31b of the sheet substrate 31 mainly constitutes the rear surface of the electromagnetic wave transmission cover 12. The sheet substrate 31 has through-holes 32. The through-holes 32 penetrate the seat base material 31 in the front-rear direction. In this embodiment, two through-holes 32 are provided in a portion of the seat base material 31 that is located on the lower side in the vertical direction of the vehicle 10 (the vertical direction in FIG. 1) and on one side in the vehicle width direction (the left side in the horizontal direction in FIG. 1). The pair of through-holes 32 are aligned with a gap between them in the vehicle width direction.

[0024] The sheet base material 31 is made of a resin material that is electromagnetically transmissive (millimeter wave transmissive). The resin material for the sheet base material 31 may be the same as the resin material exemplified for the cover base material 20. In this embodiment, the sheet base material 31 is made of PP.

[0025] As shown in FIGS. 1 and 2, the conductive portion 33 includes a heater wire 34 that generates heat when energized and a conductive plate material 35. The heater wire 34 is disposed between the front surface 31a of the seat substrate 31 and the rear surface 20b of the cover substrate 20. The heater wire 34 is approximately half-embedded in the front surface 31a of the seat substrate 31 and wired in a predetermined wiring pattern along the front surface 31a. In this embodiment, the heater wire 34 is wired in a wiring pattern having a plurality of straight portions 34a extending parallel to each other in the vertical direction of the vehicle 10 and a plurality of connecting portions 34b connecting the ends of the straight portions 34a adjacent to each other in the vehicle width direction (see FIG. 1). Both end portions 34c of the heater wire 34 in the extension direction are wired at positions overlapping the pair of through-holes 32 in the front-rear direction. The pair of end portions 34c extend parallel to each other in the vertical direction.

[0026] The heater wire 34 is formed of a resistance wire, i.e., a conductor generally having a high electrical resistance. Examples of conductive materials for the conductor include pure metals such as silver and copper, alloys such as nickel-chromium alloys (nichrome) and iron-chromium alloys, and materials in which a metal coating is formed on the surface of a base material by plating. In this embodiment, the heater wire 34 is formed of a nichrome wire.

[0027] As shown in FIGS. 1 and 2, the conductive plate 35 is a thin plate having a thickness in the front-rear direction and has a front surface 35a and a rear surface 35b. One conductive plate 35 is inserted into each of the pair of through holes 32. In this embodiment, the conductive plate 35 is press-fit into each of the through holes 32. When inserted into the through holes 32, the rear surface 35b of each conductive plate 35 is flush with the rear surface 31b of the sheet substrate 31 (see FIG. 2). The pair of conductive plates 35 have the same configuration. Therefore, hereinafter, only one conductive plate 35 (the left side in the left-right direction in FIG. 1) will be described, and a description of the other conductive plate 35 (the right side in the left-right direction in FIG. 1) will be omitted. An end 34c of the heater wire 34 is joined to the front surface 35a of the conductive plate 35. Methods for joining the end 34c to the front surface 35a include, for example, fusing, soldering, and bonding using a conductive adhesive. In this embodiment, the end 34c is joined to the front surface 35a by fusing, so that the end 34c of the heater wire 34 is electrically connected to the front surface 35a.

[0028] The conductive plate 35 is made of a conductive material. The conductive material may be the same as the conductive material exemplified for the heater wire 34. In this embodiment, the conductive plate 35 is made of a plate-shaped metal base material having a tin (Sn) plating layer formed on the surface thereof by plating.

[0029] (Wire harness 50, sealing material 70) As shown in FIGS. 1 and 2 , the wire harness 50 is a member for supplying power to the heater wire 34 of the heated seat 30. The electric wires 51 of the wire harness 50 are joined to the rear surface 35b of each conductive plate 35. Methods for joining the electric wires 51 to the rear surface 35b include, for example, fusing, soldering, and bonding using a conductive adhesive. In this embodiment, the electric wires 51 of the wire harness 50 are made of a solder alloy and are joined to the rear surface 35b by a joint 60 formed by soldering. This electrically connects the electric wires 51 of the wire harness 50 to the rear surface 35b. The wire harness 50 extends downward from the connection point in the up-down direction of the vehicle 10.

[0030] A thin-film sealing material 70 that seals the connection points between the conductive plate material 35 and the electric wires 51 of the wire harness 50 is provided. The sealing material 70 collectively covers from the rear the pair of joints 60, the rear surfaces 35b of the pair of conductive plate materials 35, and the peripheral portions 32a (see FIG. 2) of the pair of through-holes 32 on the rear surface 31b of the sheet base material 31. The sealing material 70, together with the rear surface 31b of the sheet base material 31, constitutes the rear surface of the electromagnetic wave transmission cover 12.

[0031] The sealing material 70 is formed by applying a well-known resin material used in potting treatment, such as epoxy resin, acrylic resin, urethane resin, or silicone resin, to the connection points.

[0032] <Method of manufacturing the electromagnetic wave transmission cover 12> 3 to 6, a method for manufacturing the electromagnetic wave transmission cover 12 will be described. The electromagnetic wave transmission cover 12 is formed by sequentially undergoing a step of pressing in the conductive plate material 35, a step of drawing the heater wire 34, a step of adhering the heater sheet 30, and a step of joining the wire harness 50.

[0033] 3, a sheet substrate 31 previously formed into a predetermined shape is punched out, and a pair of through holes 32 is formed using means such as laser cutting. Thereafter, a conductive plate material 35, which is a plate-shaped metal substrate having a tin plating layer (not shown) formed by plating, is press-fitted into each of the pair of through holes 32 (this is the press-fitting step of the conductive plate material 35).

[0034] Next, as shown in Fig. 4, the sheet substrate 31 is fixed to a jig 81 of a drawing device 80, and then the drawing head 82 is vibrated to embed and adhere the heater wire 34 to the front surface 31a. As a result, the heater wire 34 is laid out so as to be drawn on the front surface 31a in the predetermined pattern shown in Fig. 1 (this is the step of drawing the heater wire 34). Then, each of the end portions 34c of the heater wire 34 is joined to the front surface 35a of each conductive plate 35 by fusing, thereby obtaining the heater sheet 30.

[0035] 5, OCR is applied to the rear surface 20b of the cover substrate 20, which has been formed into a predetermined shape in advance, and the front surface 31a of the sheet substrate 31 is adhered to the rear surface 20b, thereby joining the cover substrate 20 and the heater sheet 30. This results in a main body 12A in which the heater wire 34 is disposed between the cover substrate 20 and the sheet substrate 31 (this is the step of adhering the heater sheet 30).

[0036] 6, the electric wires 51 of the wire harness 50 are joined by soldering to the rear surfaces 35b of the respective conductive plates 35 exposed rearward in the main body 12A (this is the joining step of the wire harness 50). Then, as shown in Fig. 2, a sealant 70 is applied to a portion of the rear surface 31b of the sheet base material 31 including the pair of joints 60, the rear surfaces 35b of the pair of conductive plates 35, and the peripheral portions 32a of the pair of through-holes 32. This results in an electromagnetic wave transparent cover 12 in which the connection portions between the rear surfaces 35b of the conductive plates 35 and the electric wires 51 of the wire harness 50 are sealed with the sealant 70.

[0037] <Actions and Effects of This Embodiment> (1) The electromagnetic wave transparent cover 12 includes a resin cover base material 20, a heater sheet 30 that heats the cover base material 20, and a wire harness 50 that supplies power to the heater sheet 30. The heater sheet 30 includes a resin sheet base material 31 that is laminated on the rear surface 20b of the cover base material 20 and primarily constitutes the rear surface of the electromagnetic wave transparent cover 12, a heater wire 34 that is disposed between the sheet base material 31 and the cover base material 20, and a conductive plate material 35. The sheet base material 31 has a pair of through holes 32 that penetrate in the front-rear direction and through which the conductive plate material 35 is inserted. An end 34c of the heater wire 34 is electrically connected to the front surface 35a of each conductive plate material 35. An electric wire 51 of the wire harness 50 is electrically connected to the rear surface 35b of each conductive plate material 35.

[0038] With this configuration, power is supplied to the heater wire 34 from the wire harness 50 via the conductive plate 35, causing the heater wire 34 to generate heat. Therefore, compared to conventional electromagnetic wave transparent covers that use a connector as a means for supplying power to the heater wire 34, there is no need to provide a relatively large connector housing, and the size of the electromagnetic wave transparent cover 12 is therefore less likely to be large. Therefore, the size of the electromagnetic wave transparent cover 12 can be made smaller.

[0039] Furthermore, when the heater wire 34 and the wire harness 50 are directly joined, stress acting on the wire harness 50 tends to concentrate at the connection point between the heater wire 34 and the wire harness 50. In this case, there is a risk of the heater wire 34, which has a smaller diameter than the wire harness 50, breaking. In this regard, with the above-described configuration, the heater wire 34 and the wire harness 50 are electrically connected via the conductive plate 35. This makes it difficult for the above-described stress to act on the heater wire 34. Therefore, breakage of the heater wire 34 can be suppressed.

[0040] Furthermore, with the above configuration, a flexible wire harness 50 can be used, which reduces restrictions on the arrangement of the end 34c of the heater wire 34 and the conductive plate material 35. This improves the design freedom of the electromagnetic wave transmission cover 12.

[0041] (2) The front surface 31a of the sheet substrate 31 is adhered to the rear surface 20b of the cover substrate 20 with the heater wire 34 sandwiched therebetween. When laminating the sheet substrate 31 of the heater sheet 30 onto the cover substrate 20, it is conceivable to injection-molde the cover substrate 20 using the heater sheet 30 as an insert member. However, this method presents the following problem. Specifically, the heater wire 34 disposed between the sheet substrate 31 and the cover substrate 20 comes into close contact with the rear surface 20b of the cover substrate 20 when the cover substrate 20 is molded. In this case, when the molten resin is cooled and solidified in the injection molding process, the portion of the cover substrate 20 that is in close contact with the heater wire 34 cools and solidifies faster than the other portions due to heat absorption by the heater wire 34. This results in a difference in the amount of thermal shrinkage between the portion of the cover substrate 20 that is in close contact with the heater wire 34 and the other portions. As a result, there is a risk of sink marks occurring on the front surface 20a of the cover substrate 20 at a position corresponding to the portion of the cover substrate 20 that is in close contact with the heater wire 34.

[0042] In this regard, according to the above configuration, the electromagnetic wave transparent cover 12 is manufactured by adhering the sheet base material 31, which is molded separately from the cover base material 20, to the rear surface 20b of the cover base material 20 with the heater wire 34 sandwiched between them. Therefore, the above-mentioned sink marks do not occur on the front surface 20a of the cover base material 20 due to insert molding. Therefore, it is possible to prevent the appearance of the cover base material 20, and therefore the appearance of the electromagnetic wave transparent cover 12, from being impaired.

[0043] (3) The electromagnetic wave transmitting cover 12 further includes a sealing material 70 that is formed by applying a resin material to the connection points between the rear surface 35b of the conductive plate 35 and the electric wires 51 of the wire harness 50. The sealing material 70, together with the sheet base material 31, constitutes a part of the rear surface of the electromagnetic wave transmitting cover 12.

[0044] According to this configuration, the sealing material 70 that constitutes part of the rear surface of the electromagnetic wave transmission cover 12 is formed in a thin film shape. Therefore, compared to when a sealing material is formed by injection molding a resin material, for example, it is possible to prevent the sealing material 70, and therefore the electromagnetic wave transmission cover 12, from becoming larger in size in the front-to-rear direction.

[0045] <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.

[0046] The sealing material 70 is not limited to being formed by potting a resin material as exemplified in this embodiment. For example, as long as it does not cover the entire rear surface 31b of the sheet base material 31 from behind, the sealing material may be formed by injection molding using an insert member formed by integrating the main body 12A and the wire harness 50.

[0047] In this embodiment, the joining process of the wire harness 50 and the forming process of the sealant 70 are performed after the bonding process of the heater sheet 30, but they may be performed before the bonding process. In other words, the heater sheet 30, wire harness 50, and sealant 70 integrated together may be bonded to the cover base material 20 via the adhesive layer 40.

[0048] The rear surface 35b of the conductive plate 35 does not have to be flush with the rear surface 31b of the sheet base material 31. That is, the rear surface 35b of the conductive plate 35 may be located in front of the rear surface 31b, or the rear surface 35b may be located behind the rear surface 31b.

[0049] The electromagnetic wave transparent cover 12 is not limited to one in which the cover base material 20 and the heater sheet 30 are bonded via the adhesive layer 40. For example, the electromagnetic wave transparent cover 12 may be one in which the cover base material 20 and the heater sheet 30 are bonded by injection molding the cover base material 20 using the heater sheet 30 as an insert member.

[0050] The radar device 11 is not limited to one that transmits and receives millimeter waves as illustrated in this embodiment, but may be one that transmits and receives near-infrared rays, for example. In this case, the electromagnetic wave-transmitting cover 12 as a whole only needs to be transparent to near-infrared rays.

[0051] The vehicle exterior accessory according to the present invention is not limited to one that constitutes the outer shell of the vehicle 10 at the front of the vehicle 10, and may be disposed in any position as appropriate as long as it is disposed in front of the radar device 11 in the transmission direction of the electromagnetic waves from the radar device 11. In this case, the vehicle exterior accessory may be, for example, one that constitutes the outer shell of the rear of the vehicle 10, such as a rear bumper, or one that constitutes the outer shell of the side of the vehicle 10, such as a side garnish.
