[0005] [Patent Document 1] JP 2022-114858 A Summary of the Invention [Problem to be solved by the invention]

[0006] In such vehicle exterior parts, when the supply and interruption of power to the heater seat is repeated, the socket part and the frame part undergo repeated thermal expansion and contraction. At this time, since the socket part and the frame part are made of resin materials with different linear expansion coefficients, stress is concentrated on either the socket part or the frame part. As a result, there is a risk that the one of the parts will be deformed.

[0007] An object of the present invention is to provide an exterior part for a vehicle that can suppress deformation of parts. [Means for solving the problem]

[0008] Various aspects of vehicle exterior parts for solving the above problems will be described below. [Aspect 1] An exterior part for a vehicle comprising a main body and a heater provided on the main body for heating the main body, the main body comprising a resin base material and a frame extending along an outer periphery of the base material and formed of a resin material having a different linear expansion coefficient from the base material, the base material comprising a base material main body and an outer protrusion protruding from the outer periphery of the base material main body, and when the protruding direction of the outer protrusion is defined as the protruding direction, The frame portion includes a frame main body and an inner protruding portion protruding from the frame main body in the protruding direction and embedded in the outer protruding portion, the heater section includes a heater body covering the base body, an extension section extending from the heater body and disposed between an inner surface of the outer protrusion section and an outer surface of the inner protrusion section, and a connector pin electrically connected to the extension section and protruding beyond the extension section in the protruding direction, the inner protrusion includes a base and a support protrusion that protrudes from the base along the connector pin and supports the connector pin; The inner surface of the outer protrusion and the outer surface of the base are provided with projections and recesses that engage with each other.

[0009] According to the above configuration, when the supply and interruption of power to the heater section is repeated, the outer protrusion and the inner protrusion undergo repeated thermal expansion and contraction. At this time, the uneven shapes on the inner surface of the outer protrusion and the outer surface of the base of the inner protrusion engage with each other, dispersing stress acting on the inner and outer surfaces. This prevents stress from concentrating on parts of the inner and outer surfaces. Therefore, deformation of the vehicle exterior part components can be suppressed.

[0010] [Aspect 2] The vehicle exterior part according to [Aspect 1], wherein the uneven shape is composed of a plurality of recesses and a plurality of protrusions that engage with the plurality of recesses. According to the above configuration, since the concave and convex shapes consisting of the multiple concave and convex portions are engaged with each other, the stress acting on the inner surface of the outer protrusion and the outer surface of the inner protrusion is further dispersed. This further prevents the stress from concentrating on a part of the inner surface and the outer surface. Therefore, the deformation of the parts of the vehicle exterior part can be further suppressed.

[0011] [Aspect 3] The vehicle exterior part according to [Aspect 2], wherein the base is a rectangular plate having long sides in the protruding direction, and the recesses are provided on a pair of side surfaces of the outer surface of the base along the long sides and are arranged at intervals from each other in the protruding direction.

[0012] According to the above configuration, when the base of the inner protrusion is a rectangular plate having a long side in the protruding direction, the inner protrusion is likely to thermally expand and contract along the protruding direction. In this regard, according to the above configuration, the multiple recesses are provided on a pair of side surfaces of the base and are arranged at intervals from each other in the protruding direction. Therefore, the stress acting on the inner surface of the outer protrusion and the outer surface of the inner protrusion due to the thermal expansion and thermal contraction is suitably distributed by the uneven shape consisting of the multiple recesses and multiple protrusions. Therefore, deformation of the parts of the vehicle exterior part can be suitably suppressed.

[0013] [Aspect 4] The vehicle exterior part according to [Aspect 3], wherein the distance between the multiple recesses is smaller than the length of the recesses in the protruding direction. As described above, when a plurality of recesses are provided on the pair of side surfaces of the outer surface of the base at intervals in the protruding direction, if the length of the base in the protruding direction is constant, the number of recesses decreases as the interval increases. As a result, the stress acting on the inner surface of the outer protruding portion and the outer surface of the inner protruding portion becomes less likely to be dispersed. In this regard, according to the above configuration, the interval between the plurality of recesses is smaller than the length of the recesses in the protruding direction. Therefore, it is possible to suppress the stress from becoming less likely to be dispersed. Effect of the Invention

[0014] According to the present invention, deformation of parts of vehicle exterior accessories can be suppressed. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, one embodiment of a vehicle exterior accessory will be described with reference to Figures 1 to 6. In this embodiment, the present invention is embodied as an emblem that is attached to the front of a vehicle. Hereinafter, the front and rear in the longitudinal direction of the vehicle will be simply referred to as the front and rear, and the top and bottom in the vertical direction of the vehicle when the vehicle is positioned on a horizontal plane will be simply referred to as the top and bottom.

[0017] <Emblem 12> 1 and 2, a radar device 90 that transmits and receives electromagnetic waves is mounted on a vehicle front portion 10. The radar device 90 transmits electromagnetic waves with wavelengths of 1 mm to 10 mm and frequencies of 30 GHz to 300 GHz, so-called millimeter waves, toward the front of the vehicle.

[0018] An emblem 12 that covers the radar device 90 from the front and is millimeter wave transparent is attached to a portion 11 that constitutes the outer shell of a front portion 10 of the vehicle. The front surface of the emblem 12 constitutes a design surface 12a. For ease of explanation, hereinafter, the design surface 12a side may be referred to as the front side, and the opposite side to the design surface 12a may be referred to as the back side.

[0019] The emblem 12 comprises a decorative main body portion 20 and a heater portion 60 provided on the decorative main body portion 20 for heating the decorative main body portion 20. Each component will be described in detail below.

[0020] <Decorative main body 20> As shown in FIGS. 2 and 3, the decorative main body 20 includes a base material 21, a transparent resin layer 30, a decorative layer 40, and a frame portion 50. The base material 21 is a substrate, and the transparent resin layer 30 is a decorative layer.

[0021] <Base material 21> The base material 21 is formed of a resin material and is colored. Examples of the resin material that can be used include polycarbonate (PC) resin, AES (acrylonitrile-ethylene-styrene copolymer) resin, ASA (acrylonitrile-styrene-acrylate copolymer) resin, and polymer alloys of PC resin and ABS (acrylonitrile-butadiene-styrene copolymer) resin. In this embodiment, the base material 21 is formed of PC resin.

[0022] The substrate 21 includes a substrate main body 22 and an outer protruding portion 24 that protrudes from the outer periphery of the substrate main body 22 . The base body 22 constitutes the back surface 20b of the decorative body portion 20. A protrusion 23 that protrudes forward is formed on the front surface 22a of the base body 22. The protrusion 23 is provided at a position corresponding to the pattern region 13 of the emblem 12 (see FIG. 2). The pattern region 13 is composed of a letter portion 14 of "A" and an annular portion 15 that extends along the outer edge of the design surface 12a of the emblem 12. The portion of the front surface 22a other than the protrusion 23 corresponds to a background region 16 that is the portion other than the pattern region 13 of the emblem 12.

[0023] The outer protrusion 24 is bent and extends toward the rear surface side from the outer peripheral edge of the substrate body 22. In the following description, the direction in which the outer protrusion 24 protrudes will be referred to as the protruding direction. The outer protrusion 24 has a socket portion 25 and an intermediate portion 27 located between the base body 22 and the socket portion 25 .

[0024] The socket portion 25 is a portion into which the plug portion B of the device A for supplying power, shown by the two-dot chain line in Fig. 3, is inserted and removed, and has a recess 26 that opens toward the rear. By inserting the plug portion B into the recess 26 of the socket portion 25, the heater portion 60 is electrically connected to the device A.

[0025] The intermediate portion 27 is formed with a window portion 28 that opens downward. <Transparent resin layer 30> As shown in FIGS. 2 and 3, the transparent resin layer 30 covers the surface 22a of the base material main body 22 from the front, and constitutes the surface 20a of the decorative main body portion 20.

[0026] The transparent resin layer 30 is transparently formed from a resin material. As the resin material, for example, a transparent resin such as PC resin or PMMA (polymethyl methacrylate) resin can be used. In this embodiment, it is formed from PC resin. Note that "transparent" in this embodiment includes colored transparency (colored transparency) as well as colorless transparency.

[0027] <Decorative layer 40> 3, the decorative layer 40 is disposed between the substrate body 22 and the transparent resin layer 30. The decorative layer 40 has millimeter wave transparency. The decorative layer 40 is formed by combining a colored decorative layer having a dark color such as black or blue, and a shiny decorative layer made of a metal material such as indium (In).

[0028] <Frame part 50> The frame 50 is colored and made of a resin material. More specifically, the frame 50 is black and made of a mixed material obtained by mixing a resin material with a black pigment such as carbon black. As the resin material, AES resin (linear expansion coefficient: 0.85) is used, which has a larger linear expansion coefficient than the PC resin (linear expansion coefficient: 0.7) that forms the base material 21.

[0029] As shown in FIG. 3, the frame portion 50 includes a frame main body 51 extending along the outer peripheral edge of the base material 21, and an inner protruding portion 52 protruding from the frame main body 51 in the protruding direction. The frame body 51 extends in an annular shape along the outer peripheries of both the substrate body 22 and the transparent resin layer 30 (see FIG. 2).

[0030] The inner protrusion 52 extends toward the rear surface side along the protruding direction and is embedded inside the outer protrusion 24 . As shown in FIG. 4, the inner protruding portion 52 includes a base portion 53, a pair of support projections 54 protruding from the base portion 53, and a plurality of recesses 55.

[0031] The base 53 is in the form of a rectangular plate having long sides in the protruding direction. In the following description, the direction extending parallel to the short sides is referred to as the width direction of the base 53 (the left-right direction in FIG. 4). The pair of support protrusions 54 are provided on a surface along the short side of the outer surface 53a of the base 53, i.e., on the surface 53b on the rearmost side in the protruding direction. The pair of support protrusions 54 extend in the protruding direction. The pair of support protrusions 54 are arranged with a gap between them in the width direction.

[0032] The plurality of recesses 55 are semi-circular in plan view. The bottom surface of each recess 55 is concave and curved with respect to the protruding direction. The plurality of recesses 55 are respectively provided on a pair of side surfaces 53c along the long side of the outer surface 53a of the base 53. In the present embodiment, three recesses 55 are provided on each side surface 53c. The recesses 55 are arranged side by side at intervals in the protruding direction. The length L1 of the interval between the plurality of recesses 55 is smaller than the length L2 of the recess 55 in the protruding direction. Specifically, the length L1 is preferably set to 1.3 mm or less (0 mm < L1 ≤ 1.3 mm). Further, the depth D of the recess 55 in the width direction is preferably set to 0.5 mm or more (D ≥ 0.5 mm).

[0033] Note that, at positions corresponding to the recesses 55 on the inner surface 24a of the outer protruding portion 24, a plurality of engaging convex portions 29 that engage with the recesses 55 are formed. Note that the plurality of engaging convex portions 29 correspond to the convex portions according to the present invention. Further, the uneven shape in the present invention is constituted by the plurality of recesses 55 and the plurality of engaging convex portions 29.

[0034] <Heater portion 60> As shown in FIGS. 3, 5, and 6, the heater portion 60 includes a sheet base material 61 and two heater wires 62, 63.

[0035] The sheet base material 61 is formed of a transparent resin material such as a PC resin. Each heater wire 62, 63 is formed of a metal material that generates heat when energized, and is wired on the back surface of the sheet base material 61.

[0036] The heater portion 60 includes a heater main body 64, an extension portion 65, and a connector pin 69. The heater main body 64 covers the front surface 20a of the decoration main body portion 20 and constitutes the design surface 12a of the emblem 12 (see FIG. 3). That is, the heater main body 64 covers the base material main body 22 from the front.

[0037] In the heater main body 64, the heater wires 62, 63 are wired in different wiring patterns from each other (see FIG. 5). As shown in FIGS. 3 and 6, the extension 65 is bent from the outer periphery of the heater body 64 and extends to the rear surface side in the protruding direction.

[0038] The extending portion 65 has an exposed portion 66 and a buried portion 67 . The exposed portion 66 extends from the outer periphery of the heater body 64 along the transparent resin layer 30 and the frame body 51 .

[0039] The embedded portion 67 extends further from the exposed portion 66 toward the rear surface side and is embedded between the inner surface 24 a of the outer protrusion 24 and the outer surface 53 a of the base portion 53 of the inner protrusion 52 . The embedded portion 67 has two openings 68 formed at positions corresponding to the window portion 28 to expose the heater wires 62, 63 downward from the window portion 28. The two openings 68 are spaced apart from each other in the width direction (the left-right direction in FIG. 6).

[0040] Of the heater wires 62, 63, the end portions 62a, 63a that are wired to the embedded portion 67 are electrically connected to a connector pin 69 that extends in the protruding direction. More specifically, the end portions 62a, 63a are joined to the connector pin 69 by soldering within an opening 68. Figures 3 and 6 show a joint 80 that is made of a solder alloy and formed by soldering. Note that the above-mentioned joining may be performed by adhesion using a conductive adhesive, welding, crimping, or other pressure welding other than soldering.

[0041] A water stopper 70 is provided in the window 28 to prevent water from entering the joint between the end portions 62a, 63a and the connector pin 69. The water stopper 70 is formed by filling the window 28 with a resin material, for example.

[0042] 3, 4 and 6, this embodiment is provided with two connector pins 69. The connector pins 69 are arranged at intervals from each other in the width direction (the left-right direction in FIG. 6).

[0043] The connector pin 69 has a flat plate portion 69a and a rod-shaped portion 69b extending from the flat plate portion 69a toward the rear surface side in the protruding direction. The flat portion 69 a is embedded between the outer protrusion 24 and the inner protrusion 52 .

[0044] The rod-shaped portion 69b protrudes further toward the back surface side than the extending portion 65 in the protruding direction. A base end of the rod-shaped portion 69b is supported by the supporting protrusion . A tip end of the rod-shaped portion 69b is disposed within the recess .

[0045] Next, the operation of this embodiment will be described. When the supply and interruption of power to the heater portion 60 is repeated, the outer protrusion 24 and the inner protrusion 52 repeatedly undergo thermal expansion and thermal contraction. At this time, the multiple engaging protrusions 29 and multiple recesses 55 provided on the inner surface 24a of the outer protrusion 24 and the outer surface 53a of the base portion 53 of the inner protrusion 52 engage with each other, dispersing stress acting on the inner surface 24a and the outer surface 53a. This prevents stress from concentrating on parts of the inner surface 24a and the outer surface 53a.

[0046] Next, the effects of this embodiment will be described. (1) The inner surface 24a of the outer protrusion 24 and the outer surface 53a of the base 53 are provided with the engaging protrusions 29 and the recesses 55 as recesses and protrusions that engage with each other.

[0047] This configuration provides the above-mentioned advantages, and therefore deformation of the components of the emblem 12 can be suppressed. (2) The uneven shape is constituted by a plurality of recesses 55 and a plurality of engaging protrusions 29 that engage with the plurality of recesses 55 .

[0048] With this configuration, the concave and convex shapes consisting of the multiple concave portions 55 and the multiple engaging convex portions 29 engage with each other, so that the stress acting on the inner surface 24a of the outer protrusion 24 and the outer surface 53a of the base 53 of the inner protrusion 52 is further dispersed. This further prevents stress from concentrating on parts of the inner surface 24a and the outer surface 53a. Therefore, deformation of the parts of the emblem 12 can be further suppressed.

[0049] (3) The base 53 is a rectangular plate having a long side in the protruding direction. The recesses 55 are provided on a pair of side surfaces 53c of the outer surface 53a of the base 53 along the long side, and are arranged at intervals from each other in the protruding direction.

[0050] When the base 53 of the inner protrusion 52 is a rectangular plate having a long side in the protrusion direction, the inner protrusion 52 is likely to thermally expand and contract along the protrusion direction. In this regard, according to the above configuration, the multiple recesses 55 are provided on a pair of side surfaces 53c of the base 53 and are arranged at intervals from each other in the protrusion direction. Therefore, the stress acting on the inner surface 24a of the outer protrusion 24 and the outer surface 53a of the base 53 of the inner protrusion 52 due to the thermal expansion and thermal contraction is suitably distributed by the uneven shape consisting of the multiple recesses 55 and the multiple engaging protrusions 29. Therefore, deformation of the parts of the emblem 12 can be suitably suppressed.

[0051] (4) The distance L1 between the adjacent recesses 55 is smaller than the length L2 of each recess 55 in the protruding direction. As described above, when the plurality of recesses 55 are provided on the pair of side surfaces 53c of the outer surface 53a of the base 53 at intervals in the protruding direction, if the length of the base 53 in the protruding direction is constant, the number of recesses 55 decreases as the interval increases. As a result, the stress acting on the inner surface 24a of the outer protruding portion 24 and the outer surface 53a of the base 53 of the inner protruding portion 52 becomes less likely to be dispersed. In this regard, according to the above configuration, the length L1 of the interval between the plurality of recesses 55 is smaller than the length L2 of the recesses 55 in the protruding direction. Therefore, it is possible to suppress the stress from becoming less likely to be dispersed.

[0052] <Example of change> This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

[0053] The number of heater wires in the heater portion 60 is not limited to two as exemplified in this embodiment, but may be one, or three or more. In this case, the wiring form of the heater wires is not limited to that exemplified in FIG. 5 in this embodiment, but may be changed as appropriate according to the specifications of the emblem 12.

[0054] The heater unit 60 may be appropriately arranged as long as the heater body 64 covers the base body 22. For example, in the present embodiment, the heater body 64 of the heater unit 60 covers the front surface 20a of the decorative main body 20 from the front, but the heater body 64 may cover the back surface 20b of the decorative main body 20 from the rear. In this case, the extension 65 may extend from the outer periphery of the heater body 64 through the base 21 and be embedded between the inner surface 24a of the outer protrusion 24 and the outer surface 53a of the base 53 of the inner protrusion 52.

[0055] The length L1 of the interval between the recesses 55 does not have to be smaller than the length L2 of the recesses 55 in the protruding direction as exemplified in this embodiment. For example, L1 may be equal to or greater than L2 (L1≧L2).

[0056] The shape of the recess 55 does not have to be a semicircular shape in plan view as exemplified in this embodiment. For example, the recess 55 may have a shape having a bottom surface and a pair of side surfaces rising from both ends of the bottom surface.

[0057] The shape of the inner protrusion 52 is not limited to that exemplified in this embodiment. For example, the base 53 may be a rectangular plate that is long in the width direction. In this case, the recess 55 may be provided at a position on the surface 53b that does not overlap with the support protrusion 54, and the engaging protrusion 29 that engages with the recess 55 may be provided on the inner surface 24a of the outer protrusion 24.

[0058] With this configuration, the recesses 55 and the engaging protrusions 29 engage with each other, and the support protrusions 54 engage with the inner surface 24a of the outer protrusion 24. That is, the uneven shape formed by the recesses 55 and the engaging protrusions 29 cooperates with the support protrusions 54 to achieve the same effect as that of (3) above. Therefore, deformation of the parts of the emblem 12 can be more effectively suppressed.

[0059] The uneven shape according to the present invention is not limited to that configured by the recess 55 of the inner protrusion 52 and the engaging protrusion 29 of the outer protrusion 24, as exemplified in this embodiment. For example, a recess may be provided on the inner surface 24a of the outer protrusion 24, and a protrusion that engages with the recess may be provided on the outer surface 53a of the base 53 of the inner protrusion 52, separate from the support protrusion 54.

[0060] The number and arrangement of the concave-convex shapes according to the present invention may be changed as appropriate. For example, the concave-convex shapes may be provided over the entire outer surface 53a of the base 53. The vehicle exterior part according to the present invention is not limited to the one in which the base material 21 is made of PC resin and the frame portion 50 is made of a mixed material of AES resin and carbon black as exemplified in this embodiment. The resin materials of the base material 21 and the frame portion 50 may be changed as appropriate as long as they are made of resin materials having different linear expansion coefficients. For example, the base material 21 may be made of AES resin, and the frame portion 50 may be made of a mixed material of PC resin and carbon black.

[0061] The vehicle exterior part according to the present invention is not limited to the emblem 12 exemplified in this embodiment. For example, the present invention can be applied to any vehicle exterior part having a function of decorating the vehicle, such as an ornament, a mark, a grill, or a garnish.

[0062] The vehicle exterior part according to the present invention is not limited to those having the decorative layer 40, and the decorative layer 40 may be omitted. In other words, the present invention is not limited to vehicle exterior parts having a function of decorating the vehicle, but can also be applied to vehicle exterior parts such as bumpers and covers that simply constitute the outer shell of the vehicle.

[0063] The vehicle exterior accessory according to the present invention is not limited to an accessory disposed in front of a radar device 90 that transmits and receives millimeter waves. For example, the present invention can be applied to any vehicle exterior accessory that is incorporated in a vehicle equipped with a device that transmits and receives electromagnetic waves for detecting objects outside the vehicle and has a heater disposed on the surface side of the main body. In this case, the electromagnetic waves transmitted and received by the radar device 90 include infrared rays and the like in addition to millimeter waves.

[0064] The vehicle exterior accessory according to the present invention may be disposed in front of a radar device that transmits and receives electromagnetic waves to detect objects outside the vehicle, and may be disposed in a position where it is appropriate, without being limited to the front part 10 of the vehicle. For example, if the radar device is for rear monitoring, the vehicle exterior accessory is disposed in front of the radar device in the transmission direction of the electromagnetic waves, and at the rear of the vehicle relative to the radar device. The same applies to the case where the radar device is used for front-side monitoring or rear-side monitoring.

[0065] The vehicle exterior accessory according to the present invention may be applied to a vehicle that is not equipped with a radar device that transmits and receives electromagnetic waves to detect objects outside the vehicle. [Explanation of symbols]
