Description

Technical Field

[0001] This disclosure relates to external components for vehicles. Background Technology

[0002] Vehicles such as automobiles are equipped with radar devices that transmit and receive electromagnetic waves, such as millimeter waves, used to detect objects outside the vehicle. The radar device sends these electromagnetic waves outwards and receives the reflected waves (reflected waves) that are reflected back after hitting objects outside the vehicle. The radar device detects objects outside the vehicle by transmitting and receiving these electromagnetic waves. To make the radar device less visible from outside the vehicle, it is advisable to install an external component, such as a vehicle emblem, in front of the radar device in the direction of electromagnetic wave transmission.

[0003] The aforementioned exterior component for a vehicle includes a cover and a housing located in front of a radar device in the direction of electromagnetic wave transmission. The cover and housing are formed of a material capable of allowing the electromagnetic waves to pass through. The housing is a component that covers the surface of the cover facing the radar device. The cover includes a decorative section for enhancing the aesthetics of the vehicle's exterior component. As such a vehicle exterior component, a known luminous emblem illuminates the decorative section of the cover to make it glow in order to improve its aesthetics.

[0004] Japanese Patent Application Publication No. 2011-93378 describes an embodiment 1 in which a plate-shaped light guide is disposed on the rear side of the cover of a vehicle exterior component (illuminated vehicle emblem), i.e., on the radar device side, and a substrate having a light-emitting portion for irradiating light toward the light guide is disposed on the outer edge of the light guide. In this case, light incident from the light-emitting portion onto the light guide diffuses within the light guide, thereby causing the entire light guide to illuminate. As a result, the decorative portion of the cover receives light from the light guide and illuminates uniformly.

[0005] Furthermore, Embodiment 2 of the aforementioned publication describes a substrate with a light-emitting portion disposed on the rear side of the cover of the vehicle exterior component (illuminated emblem) and outside the transmission range of electromagnetic waves transmitted from the radar device, and light from the light-emitting portion is directly irradiated toward the decorative portion of the cover. The substrate with the light-emitting portion is disposed as described above to prevent electromagnetic waves transmitted from the radar device from passing through. In this case, the light guide as in Embodiment 1 of the aforementioned publication can be omitted, thus simplifying the structure of the vehicle exterior component.

[0006] If a light guide is disposed on the rear side of the vehicle exterior component as in Embodiment 1 of the above-described publication, electromagnetic waves transmitted from the radar device pass through the light guide. Even if the light guide is made of a material that allows electromagnetic waves to pass through, the transmittance of electromagnetic waves in the vehicle exterior component reduces the amount of attenuation of electromagnetic waves transmitted from the radar device when passing through the aforementioned light guide.

[0007] Furthermore, as in Embodiment 2 of the aforementioned publication, omitting the light guide can suppress the reduction in electromagnetic wave transmittance in the vehicle exterior component. In this case, it is necessary to arrange the light-emitting part outside the transmission range of the electromagnetic waves transmitted from the radar device, and to point the light-emitting part in a manner that directs the light from the light-emitting part toward the decorative part of the cover. When light is irradiated from the light-emitting part toward the decorative part of the cover, the light from the light-emitting part is deflected in the irradiation direction relative to the decorative part, making it difficult to make the decorative part of the cover emit light uniformly. In addition, in order to make the light-emitting part point the light from the light-emitting part toward the decorative part of the cover, it is possible to adopt a flexible structure for the substrate having the light-emitting part and to bend the substrate so that the light from the light-emitting part is pointed in the manner described above. However, flexible substrates are expensive, thus increasing the manufacturing cost of the vehicle exterior component. Summary of the Invention

[0008] One aspect of this disclosure relates to an exterior component for a vehicle, comprising a cover and a housing located in front of a radar device mounted on the vehicle in the direction of electromagnetic wave transmission. The housing covers the surface of the cover on the side facing the radar device, and the decorative portion is made to emit light by illuminating a decorative portion of the cover with light from a light-emitting portion disposed inside the housing. In the vehicle exterior component, a flat substrate is disposed inside the housing, and the light-emitting portion is provided on the substrate. The substrate is disposed outside the electromagnetic wave transmission range, and a lens is disposed inside the housing, which reflects the light from the light-emitting portion toward the decorative portion.

[0020] Figure 12 This is a cross-sectional view showing other examples of external components used in vehicles. Detailed Implementation

[0021] The following is for reference Figures 1-10 One embodiment of an external component for a vehicle will be described.

[0022] Figure 1 The illuminated car emblem 12 is shown as an exterior component for a vehicle. Figure 2 Showing the view from the direction of arrow 2-2 Figure 1 The illuminated car emblem 12 is in a certain state. As an illuminated car emblem 12, it is envisioned to have a structure that is embedded in an opening formed in the exterior panel of a vehicle such as a car. Examples of such exterior panels include: panels without vents such as bumpers, panels with vents such as grilles, and decorative panels such as trim panels.

[0023] like Figure 2As shown, a radar device 11 is installed in a vehicle. The radar device 11 transmits millimeter waves, which are electromagnetic waves, outwards and receives the reflected millimeter waves, i.e., the reflected waves, which are reflected back after hitting objects outside the vehicle. The radar device 11 detects objects outside the vehicle by transmitting and receiving these millimeter waves. The transmission range of the millimeter waves of the radar device 11 is, for example... Figure 2 The area indicated by the double-dotted line L1. The aforementioned luminous vehicle emblem 12 is positioned forward of the vehicle's radar device 11 in the direction of millimeter wave transmission. Figure 2 To the left. As a result, the luminous emblem 12 makes the radar device 11 less visible from outside the vehicle.

[0024] <Summary of Illuminated Car Emblem 12>

[0025] The illuminated emblem 12 includes a cover 13 and a housing 14 located in front of the radar device 11 in the direction of millimeter wave transmission. The cover 13 and housing 14 are formed of a material capable of transmitting electromagnetic waves such as millimeter waves. The housing 14 is positioned opposite the side of the cover 13 closest to the radar device 11. Figure 2 Cover the right side of the surface.

[0026] The cover 13 includes a decorative portion 15 and a frame portion 16. The decorative portion 15 is a component used to enhance the appearance of the luminous emblem 12, and is formed of a substrate 17, a light diffusion layer 18, and a decorative layer 19. The substrate 17 is formed of resin in a sheet shape. The substrate 17 allows millimeter waves to pass through and allows visible light to pass through. The aforementioned frame portion 16, made of resin, is fused to the outer edge of the substrate 17. The frame portion 16 is a component for mounting the housing 14 and extends in a ring shape along the outer edge of the substrate 17.

[0027] Figure 3 The cross-section of the decorative portion 15 of the cover 13 and its surrounding area is shown in enlarged form. The rear surface of the substrate 17 of the decorative portion 15 is shown... Figure 3 A light diffusion layer 18 is formed on the right surface of the substrate 17. The light diffusion layer 18 allows millimeter waves to pass through. Furthermore, the light diffusion layer 18 allows incident light to pass through and diffuse. On the front surface of the substrate 17... Figure 3 A decorative layer 19 that allows millimeter waves to pass through is formed on the left surface of the cover. The front surface of the substrate 17 and the decorative layer 19 are covered by a transparent layer 27 made of transparent resin or the like. A hard coating 28 for protection is formed on the front surface of the transparent layer 27. The transparent layer 27 and the hard coating 28 allow millimeter waves to pass through and also allow visible light to pass through. Therefore, the decorative part 15 of the cover 13 can be seen from outside the vehicle through the transparent layer 27 and the hard coating 28.

[0028] Figure 2The housing 14 shown is formed of a material such as resin that allows millimeter waves to pass through. The housing 14 includes a flange 21 and a protrusion 22. The flange 21 protrudes toward the frame 16 of the cover 13 at a position corresponding to the outer edge of the cover 13, i.e., the frame portion 16. Similar to the frame portion 16 of the cover 13, the flange 21 extends in a ring along the outer edge of the cover 13. Furthermore, by mounting the flange 21 to the frame portion 16, the housing 14 is positioned to cover the surface of the cover 13 on the side closest to the radar device 11. The protrusion 22 is located at a portion of the housing 14 closer to the center of the cover 13 than the flange 21. The protrusion 22 is formed by bending the aforementioned portion of the housing 14 (the portion closer to the center of the cover 13 than the flange 21) toward the cover 13. By forming this protrusion 22 on the housing 14, the distance between the cover 13 and the housing 14 in the luminous emblem 12 can be shortened; therefore, the size of the luminous emblem 12 can be reduced to a smaller size.

[0029] Figure 4 An enlarged cross-section of the portion of the protrusion 22 of the housing 14 facing the cover 13 is shown. (See image from...) Figure 4 As is known, a white layer 23 is formed in the portion of the protrusion 22 facing the cover 13. This white layer 23 reflects and diffuses incident light. The reflection of light incident on the white layer 23 by the white layer 23 is preferably total internal reflection. Furthermore, the white layer 23 does not necessarily have to appear white due to the incident light; it can simply function as a diffusion layer to diffuse the incident light. The protrusion 22 and the white layer 23 allow millimeter waves to pass through.

[0030] Figure 2 The illuminated emblem 12 shown is a component that illuminates the decorative portion 15 of the cover 13 by irradiating it with light. Inside the housing 14, a flat substrate 25 is disposed between the flange 21 and the protrusion 22, and a light-emitting portion 24 is provided on the substrate 25. The light-emitting portion 24 is a component for irradiating light onto the decorative portion 15 of the cover 13, and may be, for example, an LED. The decorative portion 15 is illuminated by light from the light-emitting portion 24. The substrate 25 on which the light-emitting portion 24 is provided does not easily allow millimeter waves to pass through; therefore, it extends in a ring shape outside the millimeter wave transmission range of the radar device 11, in a manner that surrounds the transmission range. The light-emitting portions 24 are arranged at predetermined intervals along the ring-shaped substrate 25.

[0031] The aforementioned flat substrate 25 is disposed between the flange 21 and the protrusion 22 inside the cover 13, and extends in a ring shape at this location. Therefore, the direction in which the substrate 25 points, in other words, the direction of light irradiation from the light-emitting part 24, is substantially the same as the direction of millimeter wave transmission in the radar device 11. As a result, it is difficult to allow light from the light-emitting part 24 of the substrate 25 to irradiate the decorative part 15 of the cover 13 from between the flange 21 and the protrusion 22. To solve this problem, a lens 26 is disposed inside the housing 14 between the flange 21 and the protrusion 22, and in the direction of millimeter wave transmission of the radar device 11, forward of the light-emitting part 24. The lens 26 is used to reflect the light from the light-emitting part 24 towards the decorative part 15.

[0032] <Angles and dimensions of various positions of the illuminated car emblem 12>

[0033] Figure 5 The coordinate graph shows the attenuation of millimeter waves transmitted and received by radar device 11 as they pass through the protrusion 22 of housing 14. The horizontal axis of the graph is the angle of the portion of protrusion 22 facing the cover 13; more specifically, it is the angle of that portion relative to the transmission direction of the millimeter waves from radar device 11. Figure 2 The tilt angle formed by the planes orthogonal to the single-dot dashed line. The attenuation of the millimeter wave, represented by the vertical axis of the above coordinate graph, is as follows relative to the increase of the aforementioned tilt angle: Figure 5 The tilt angle becomes smaller as shown by the solid line. Furthermore, it is advisable to set the tilt angle of the illuminated logo 12 to, for example, 1° or more, preferably 3° or more. In addition, the upper limit of the tilt angle is determined by design factors such as the size of the illuminated logo 12. The tilt angle is smaller than the upper limit.

[0034] Figure 6 The coordinate graph shows the attenuation of millimeter waves transmitted and received by radar device 11 as they pass through the protrusion 22 of housing 14 and cover 13. The horizontal axis of the graph is the distance between the center of cover 13 and the center of protrusion 22 of housing 14. The attenuation of the millimeter waves, represented by the vertical axis of the graph, relative to the change in this distance is as follows: Figure 6 The change is as shown by the solid line. (As from...) Figure 6 As is known, there exists a value among the aforementioned distances that minimizes the attenuation of the millimeter wave. Compared to this value, the shorter the distance, the greater the attenuation of the millimeter wave; conversely, the longer the distance, the greater the attenuation of the millimeter wave. The distance at which the attenuation of the millimeter wave is minimized is an integer multiple of half the wavelength of the millimeter wave. Furthermore, the aforementioned distance of the luminous car emblem 12 adopts a value within a predetermined range, including the value that minimizes the attenuation of the millimeter wave.

[0035] Figure 7The coordinate graph shows the attenuation of millimeter waves transmitted and received by radar device 11 after passing through the protrusion 22 and cover 13 of housing 14. This attenuation of the millimeter waves is caused by the millimeter waves transmitted from radar device 11 hitting the flange 21 and being reflected to a certain extent. That is, because the millimeter waves hitting the flange 21 and being reflected approach each other, interference occurs between the millimeter waves in front of the luminous emblem 12 in the direction of transmission of the millimeter waves from radar device 11. This interference between the millimeter waves causes attenuation of the millimeter waves after passing through the protrusion 22 and cover 13 of housing 14.

[0036] Figure 7 The horizontal axis of the coordinate graph represents the angle of flange 21 in housing 14, specifically the angle of flange 21 relative to... Figure 2 The angle of inclination formed by the single-dotted line is shown. The attenuation of the millimeter wave, as shown on the vertical axis of the above coordinate graph, is as follows relative to the increase in the angle of flange 21. Figure 7 The angle of the flange 21 decreases as shown by the solid line. This is because, on the one hand, if the angle of the flange 21 is small, the millimeter waves reflected by the flange 21 tend to travel in close proximity to each other, thus easily causing interference between the millimeter waves. On the other hand, if the angle of the flange 21 is large, it suppresses the situation where the millimeter waves reflected by the flange 21 travel in close proximity to each other, thus making it less likely for millimeter waves to interfere with each other.

[0037] The angle of the flange 21 in the illuminated logo 12 can be set to, for example, 1° or more, preferably 3° or more. Furthermore, the upper limit of the angle of the flange 21 is determined by design factors such as the size of the illuminated logo 12. The angle of the flange 21 is smaller than the aforementioned upper limit. Additionally, Figure 7 In the case where the angle of flange 21 is between 0° and 5°, the attenuation of the millimeter wave remains unchanged. This is because the attenuation includes the aforementioned attenuation of the luminous logo 12. Figure 5 The tilt angle shown Figure 6 The distances shown and those described later Figure 8 The influence of the distance shown. Excluding these influences, when the angle of flange 21 is 0° to 5°, the larger the angle, the smaller the aforementioned attenuation gradually becomes.

[0038] Figure 8 The coordinate graph also shows the attenuation of millimeter waves transmitted and received by radar device 11 as they pass through the protrusion 22 and cover 13 of housing 14. The horizontal axis of this coordinate graph represents the transmission range of the millimeter waves of radar device 11. Figure 2 The distance between the area indicated by the double-dotted line L1 and the substrate 25 arranged to enclose that area. The attenuation of the millimeter wave, as shown on the vertical axis of the graph, corresponds to the reduction in this distance. Figure 8 It becomes smaller as shown by the solid line. Furthermore, the aforementioned distance of the illuminated car emblem 12 is set to be greater than... Figure 8 The attenuation of the millimeter wave, indicated by the solid line, is a predetermined level value.

[0039] <Lens 26>

[0040] like Figure 9 As shown, lens 26 is located in front of the light-emitting part 24 in the millimeter wave transmission direction of radar device 11. Figure 9 To the left. Light from the light-emitting part 24 shines in front of the radar device 11 in the millimeter wave transmission direction, i.e., towards the cover 13. A reflecting surface 29 and a refractive surface 30 are formed on the lens 26. The reflecting surface 29 is used to reflect the light from the light-emitting part 24 towards the decorative part 15 of the cover 13. The refractive surface 30 is used to refract the light reflected by the reflecting surface 29 so that the light avoids the angle near the flange 21 in the protrusion 22. In addition, Figure 9 The dashed arrows in the diagram indicate the path of light from the light-emitting unit 24.

[0041] Figure 10 The dashed arrow indicates that no formation was formed on lens 26. Figure 9 In this case, the path of light traveling from the light-emitting part 24 is determined by the refractive surface 30. If a protrusion 22 is formed on the housing 14 to reduce the size of the luminous emblem 12, the light from the light-emitting part 24 is reflected by the reflecting surface 29 of the lens 26 and then blocked by the corner of the protrusion 22 near the flange 21. As a result, less light reaches the decorative part 15 of the cover 13. However, if a refractive surface 30 is formed on the lens 26... Figure 9 With such a refractive surface 30, the light reflected by the reflective surface 29 is refracted through the refractive surface 30, thus suppressing the situation where the light is blocked by the aforementioned angle of the protrusion 22.

[0042] Next, the effects of the luminous car emblem 12 in this embodiment will be explained.

[0043] (1) Inside the housing 14 and outside the transmission range of the millimeter waves generated by the radar device 11, a flat substrate 25 with a light-emitting portion 24 is provided, extending in a ring shape to surround the transmission range. Even if the light-emitting portion 24 is not pointing towards the decorative portion 15 of the cover 13, the light from the light-emitting portion 24 is reflected by the reflective surface 29 of the lens 26 and irradiates the decorative portion 15 of the cover 13. As a result, the decorative portion 15 of the cover 13 emits light. Therefore, it is not necessary to use an expensive, flexible substrate 25 to achieve the purpose of making the light-emitting portion 24 point towards the decorative portion 15 in order to irradiate the decorative portion 15 with light from the light-emitting portion 24. As a result, the manufacturing cost of the luminous emblem 12 can be kept low. In other words, the decorative portion 15 of the cover 13 of the luminous emblem 12 can be made luminous at a low cost.

[0044] (2) Even without arranging a conventional light guide between the decorative part 15 of the cover 13 and the radar device 11, light from the light-emitting part 24 can be irradiated onto the decorative part 15 of the cover 13 to make the decorative part 15 glow. In this case, the millimeter wave transmittance of the luminous emblem 12 can be suppressed along with the reduction of this transmittance, corresponding to the situation where the millimeter wave transmitted from the radar device 11 does not pass through the aforementioned light guide. Moreover, the size of the luminous emblem 12 can be reduced accordingly, so that the aforementioned light guide is not required.

[0045] (3) A substrate 25 with a light-emitting portion 24 is disposed between the flange 21 and the protrusion 22 inside the housing 14. Light from the light-emitting portion 24 is reflected toward the decorative portion 15 of the cover 13 by the reflecting surface 29 of the lens 26 disposed between the flange 21 and the protrusion 22 inside the housing 14. The situation where the reflected light is blocked by the corner of the protrusion 22 of the housing 14 is suppressed because the light is refracted by the refractive surface 30 of the lens 26 in a way that avoids the corner of the protrusion 22. Therefore, it is possible to suppress the situation where less light from the light-emitting portion 24 reaches the decorative portion 15 of the cover 13.

[0046] (4) If light from the light-emitting part 24 shines on the decorative part 15 of the cover 13, the light is incident on the light-diffusing layer 18 of the decorative part 15. The light-diffusing layer 18 appears to emit light because it allows the incident light to pass through and diffuse. As a result, the appearance of the decorative part 15 can be further improved.

[0047] (5) Light from the light-emitting part 24 incident on the light diffusion layer 18 of the decorative part 15 of the cover 13 is reflected to some extent by the light diffusion layer 18 and sent to the protrusion 22 side of the housing 14, and then reaches the white layer 23 of the protrusion 22 of the housing 14. Light incident on the white layer 23 is reflected to some extent by the white layer 23 and sent to the light diffusion layer 18 of the decorative part 15 of the cover 13. Thus, the light is reflected multiple times between the light diffusion layer 18 and the white layer 23, thereby enabling the decorative part 15 of the cover 13 to emit light uniformly.

[0048] Furthermore, the above-described embodiments can also be modified as follows. The above-described embodiments and the following modifications can be combined and implemented within the scope of technical non-contradiction.

[0049] It can also be like... Figure 11 As shown, the light diffusion layer 18 is formed on the front surface of the substrate 17. Figure 11 The left surface. In this case, a decorative layer 19 is formed on the front surface of the light diffusion layer 18, and the front surface of the light diffusion layer 18 and the decorative layer 19 are covered by a transparent layer 27.

[0050] • The reflection of light incident on the white layer 23 by the white layer 23 does not necessarily have to be total internal reflection.

[0051] Alternatively, one of the light diffusion layer 18 and the white layer 23 can be omitted, or both can be omitted.

[0052] Alternatively, the refractive surface 30 of the lens 26 may be omitted depending on the shape of the protrusion 22 of the housing 14.

[0053] Alternatively, the radar device 11 can transmit and receive electromagnetic waves other than millimeter waves, such as infrared or laser.

[0054] • As an exterior component for vehicles, an example is an illuminated emblem 12 embedded in an opening of an exterior panel, but it could also be, for example, an luminous emblem 12 made of an exterior panel. Figure 12 The cover 13 of the illuminated car emblem 12 shown is integrated with the exterior panel 31, thereby making the exterior panel 31 an exterior component for a vehicle. Examples of exterior panels 31 used in this case, which are exterior components for vehicles, include panels without vents such as bumpers, panels with vents such as grilles, and decorative panels such as trim panels.

[0055] • Alternatively, the installation position of the vehicle exterior accessories relative to the vehicle can be any position among the front, side, and rear of the vehicle.
