Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in a conventional light-emitting emblem including such a lighting device, the outer lens is fixed to the housing from the viewpoint of water-stopping performance, thereby sealing the space surrounded by the outer lens and the housing. However, in this case, it becomes difficult to replace only the light source when a problem occurs in the light source.

[0006] An object of the present invention is to provide a light-emitting emblem that can maintain water-stopping performance and enables easy replacement of the light source.

Means for Solving the Problems

[0007] The following describes various embodiments of the luminous emblem that address the above-mentioned problems. [Aspect 1] A light-emitting emblem comprising a light source, a housing having an opening that opens toward the outside of the vehicle, and a cover having a transparent portion that transmits visible light and that closes the opening, wherein the light-emitting emblem emits light toward the outside of the vehicle by transmitting light from the light source toward the transparent portion, the housing having a through hole that penetrates the wall of the housing and into which the light source is detachably attached, and when the light source is attached to the through hole, a sealed space is formed that is sealed from the outside by the light source, the housing and the cover.

[0008] With the above configuration, the light source can be removed through the through-hole in the housing. Furthermore, by reattaching the light source to the through-hole and transmitting light from the light source through the translucent section, an illuminated display can be projected outwards from the vehicle. However, if the light source is simply attached to the through-hole, there is a risk of water droplets entering the housing through the gap between the part of the housing wall that constitutes the through-hole and the light source. With the above configuration, when the light source is attached to the through-hole, a sealed space is formed by the light source, housing, and cover, which are sealed from the outside. Therefore, the entry of water droplets into the housing is suppressed. Thus, the light source can be easily replaced while maintaining watertight performance.

[0009] [Aspect 2] The light-emitting emblem according to [Aspect 1], wherein a reflective member is provided between the cover and the housing, covering the light source from the front in the direction of light emission from the light source and reflecting the light, the reflective member is provided with a convex portion that protrudes toward the light source at a position facing the light source in the emission direction and has an inclined surface that is inclined with respect to the optical axis of the light source, and the inner surface of the housing is configured to reflect the light toward the cover.

[0010] When the light source is not illuminated, it may be visible from outside the vehicle through the translucent portion. In this case, the appearance of the illuminated emblem is diminished. In this regard, with the above configuration, the light source is covered by a reflective material from the front. As a result, the light source is less visible from outside the vehicle through the translucent portion. Therefore, the deterioration of the appearance of the illuminated emblem can be suppressed.

[0011] On the other hand, if a member is simply provided to cover the light source from the front in the direction of emission, the light from the light source is blocked by the member, making it difficult to efficiently transmit the light to the transparent part. In this respect, with the above configuration, the light emitted from the light source is reflected by the reflective member. Here, the reflective member is provided with a convex portion having an inclined surface at a position facing the light source in the direction of emission. Therefore, the light is reflected by the inclined surface and diffused outwards from the convex portion. The diffused light is then reflected once or multiple times between the inner surface of the housing and the reflective member before being reflected towards the cover. The light that thus enters the cover is transmitted through the transparent part and illuminated outwards from the vehicle. In other words, an illumination display is made outwards from the vehicle. Therefore, even if a member is provided to cover the light source from the front in the direction of emission, the light from the light source can be efficiently transmitted to the transparent part.

[0012] [Aspect 3] The reflective member is provided on the outer circumference of the convex portion and comprises a projection having an opposing surface that faces the inclined surface in a direction perpendicular to the axial direction of the optical axis, and a hole provided between the convex portion and the projection, and is configured to reflect the light reflected by the inclined surface and incident on the opposing surface of the projection through the hole toward the transmissive portion, as described in [Aspect 2].

[0013] According to the above configuration, some of the light reflected by the inclined surface of the convex portion enters the opposite surface of the protruding portion. The light that enters the opposite surface is reflected through the hole towards the transmissive portion. Therefore, light from the light source can be transmitted to the transmissive portion more efficiently.

[0014] [Aspect 4] The light-emitting emblem according to [Aspect 3], wherein the transparent portion is provided in the central and outer edges of the cover, the wall portion comprises a bottom wall having the through hole, a side wall constituting the opening, and a connecting wall connecting the bottom wall and the side wall, the connecting surface constituting the connecting wall among the inner surfaces is inclined with respect to the optical axis, the reflecting member is configured to reflect the light reflected by the inclined surface and incident on the opposing surface of the protruding portion through the hole toward the transparent portion in the central part, and the housing is configured to reflect the light reflected by the inclined surface and incident on the connecting surface toward the transparent portion in the outer edge.

[0015] According to the above configuration, some of the light reflected by the inclined surface of the protrusion enters the opposite surface of the protrusion. The light that enters the opposite surface is reflected through the hole towards the transparent section provided in the center of the cover. In addition, some of the light reflected by the inclined surface of the protrusion enters the connecting surface of the housing. The light that enters the connecting surface is reflected towards the transparent section provided on the outer edge of the cover. Therefore, light from the light source can be uniformly transmitted through the transparent section of the cover.

[0016] [Aspect 5] The reflective member and the housing are white in color, which reflects the light, as described in any one of [Aspect 2] to [Aspect 4]. According to the above configuration, the reflection efficiency of light from the light source can be increased in the reflective member and housing. Therefore, light from the light source can be transmitted to the transmissive portion more efficiently. [Effects of the Invention]

[0017] According to the present invention, the light source can be easily replaced while maintaining water-stopping performance. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0019] Hereinafter, referring to FIGS. 1 to 5, an embodiment of the light-emitting emblem 13 will be described. In the following, the front and rear in the front-rear direction L of the vehicle 10 where the light-emitting emblem 13 is provided are simply referred to as the front and the rear, respectively. Also, the upper and lower in the vertical direction Z of the vehicle 10 are simply referred to as the upper and the lower, respectively.

[0020] As shown in FIGS. 1 and 2, an exterior panel 11 constituting the front portion 10a of the vehicle 10 is provided with a window portion 12 that opens forward. A light-emitting emblem 13 is attached to the window portion 12.

[0021] The light-emitting emblem 13 emits light and displays it forward, that is, outward of the vehicle 10, and has a light source unit 20, a housing 30, a cover 40, and a reflecting member 50. <00​​​​​​​​​​The case 21 has a disc-shaped base portion 22 and a cylindrical wall portion 23 that protrudes forward from the base portion 22. Inside the cylindrical wall portion 23 is housed a circuit board (not shown) on which one or more light-emitting elements are mounted. For example, light-emitting diodes (LEDs) can be used as the light-emitting elements.

[0024] Multiple claw portions 24 are provided on the outer circumferential surface 23a of the cylindrical wall portion 23. The multiple claw portions 24 are arranged at intervals from each other along the entire circumference of the outer circumferential surface 23a. The heat dissipation section 25 dissipates the heat generated by the light-emitting element to the outside and is connected to the rear end of the case 21 by screws or the like. The heat dissipation section 25 is thermally connected to the circuit board while being electrically insulated.

[0025] The sealing member 26 is formed in an annular shape from an elastic material such as rubber and is attached to the outer circumferential surface 23a of the cylindrical wall portion 23. The sealing member 26 is positioned between the base portion 22 and the plurality of claw portions 24 so as to abut against the base portion 22.

[0026] <Housing 30> As shown in Figures 1 and 2, the housing 30 has an opening 31 that opens toward the front, i.e., outward, of the vehicle 10, and a wall portion 30A that forms the opening 31.

[0027] The wall portion 30A is formed of a resin material in which white light-diffusing particles are dispersed, and is therefore white overall. As the resin material, for example, acrylonitrile-butadiene-styrene copolymer (ABS) resin can be used. As the light-diffusing material, for example, metal oxides such as titanium dioxide and zinc oxide can be used.

[0028] The inner surface 30a of the wall portion 30A forms a reflective surface that reflects visible light (hereinafter simply referred to as light). The wall portion 30A has a bottom wall 32 facing the opening 31 in the front-rear direction L, a side wall 34 that constitutes the opening 31, and a connecting wall 33 that connects the bottom wall 32 and the side wall 34.

[0029] The bottom wall 32 is disc-shaped with an axis A extending in the front-to-back direction L as its center. A through-hole 35 is provided in the center of the bottom wall 32, into which the light source unit 20 is detachably attached.

[0030] The through-hole 35 penetrates the bottom wall 32 in the front-to-back direction L. The through-hole 35 extends along a virtual circle C centered on axis A and has a plurality of restricting edges 35a that restrict the insertion and removal of the claw portion 24 of the light source unit 20, and a plurality of notches 35b that allow the insertion and removal of the claw portion 24.

[0031] The case 21 and through-hole 35 are configured such that, when the light source unit 20 is in the first position shown in Figure 2, the case 21 can be inserted into and removed from the through-hole 35 by the claw portion 24 and the notch 35b. On the other hand, when the light source unit 20 is in the second position (see Figure 3), rotated by a predetermined angle around axis A from the first position, the case 21 and through-hole 35 are configured such that the case 21 cannot be inserted into and removed from the through-hole 35 by the claw portion 24 and the restricting edge portion 35a. Note that when the light source unit 20 is in the second position, the restricting edge portion 35a and the claw portion 24 are in positions that overlap each other in the front-to-back direction L.

[0032] As shown in Figure 3, a light source unit 20 is mounted in the through-hole 35 so as to emit light toward the front of the vehicle 10. At this time, the optical axis of the light source unit 20 coincides with axis A. Also, as described above, since the light source unit 20 emits light toward the front of the vehicle 10, the direction of light emission from the light source unit 20 is from the rear to the front of the vehicle 10. The front in the direction of light emission coincides with the front of the vehicle 10, and the rear in the same direction of emission coincides with the rear of the vehicle 10.

[0033] With the light source unit 20 installed in the through hole 35, the sealing member 26 is pressed against the portion of the bottom wall 32 that constitutes the through hole 35. The sealing member 26 is pressed against both the above portion and the base portion 22, thereby sealing the space between the through hole 35 and the case 21 of the light source unit 20.

[0034] As shown in Figures 2 and 3, the connecting wall 33 rises forward from the outer peripheral edge of the bottom wall 32 and extends at an inclination with respect to axis A. Accordingly, the connecting surface 33a that constitutes the connecting wall 33 among the inner surface 30a is also inclined with respect to axis A. More specifically, the connecting surface 33a is inclined toward the outer peripheral side as it moves forward in the front-rear direction L.

[0035] The connecting wall 33 is configured to reflect light incident on the connecting surface 33a forward (see Figure 5). The side wall 34 bends forward from the connecting wall 33. The front end 34a of the side wall 34 forms the opening 31.

[0036] <Cover 40> As shown in Figures 2 to 4, the cover 40 is circular in plan view and is welded to the front end 34a of the side wall 34. The cover 40 is welded to the front end 34a all around. In other words, the opening 31 of the housing 30 is closed from the front by the cover 40. As for the welding method, for example, ultrasonic welding, laser welding, hot plate welding, etc. can be used.

[0037] With the light source unit 20 installed in the through hole 35, a sealed space S is formed by the light source unit 20, the housing 30, and the cover 40, which are sealed from the outside (see Figure 3).

[0038] The cover 40 has an inner portion 41 and an outer portion 44 located in front of the inner portion 41. The inner portion 41 is a so-called outer lens and is formed of a transparent material that transmits visible light. As the transparent material, for example, acrylic resins such as polymethyl methacrylate (PMMA) or transparent resins such as polycarbonate (PC) resin can be used. In this embodiment, "transparent" includes not only colorless transparent material but also colored transparent material.

[0039] A first exposed portion 42 and a second exposed portion 43 are integrally formed on the front surface 41a of the inner portion 41 as protruding portions. The second exposed portion 43 is formed on the outer edge of the inner portion 41, that is, on the outer edge of the cover 40, and is located in front of the connecting surface 33a of the connecting wall 33. The first exposed portion 42 is formed in the central part of the inner portion 41, that is, in the central part of the cover 40. Here, the central part of the cover 40 in this embodiment is the part of the cover 40 that is located on axis A side than the second exposed portion 43.

[0040] The outer portion 44 has a light-shielding portion 45 that blocks light and a light-transmitting portion 46 that is surrounded by the light-shielding portion 45 and has visible light transmittance. In this embodiment, the portion of the outer portion 44 other than the light-transmitting portion 46 is made up of the light-shielding portion 45.

[0041] The central portion 45a of the light-shielding portion 45 is formed from a mixed material, such as a resin material like PC resin, and a black pigment like carbon black. The outer edge portion 45b of the light-shielding portion 45 is formed by applying a light-shielding coating or plating to the surface of a base material, such as a resin material like PC resin or ABS resin. The outer edge portion 45b covers the welded portion between the front end 34a of the side wall 34 and the inner portion 41 from the front.

[0042] The permeable portion 46 is a communication hole that connects the inside and outside of the outer portion 44. The transparent portion 46 exposes a first exposed portion 42 towards the front of the vehicle 10 at the central part of the cover 40. The transparent portion 46 also exposes a second exposed portion 43 towards the front of the vehicle 10 at the outer edge of the cover 40. The design surface 13a of the luminous emblem 13 is formed by the first exposed portion 42 and the second exposed portion 43 exposed forward by the transparent portion 46 and the light-shielding portion 45.

[0043] As shown in Figure 4, the first exposed portion 42 and the second exposed portion 43 correspond to the pattern area 14 of the design surface 13a, which displays a logo or other pattern facing the front of the vehicle 10. Specifically, the first exposed portion 42 corresponds to the central portion 14a of the pattern area 14, which displays characters, symbols, etc. The second exposed portion 43 corresponds to the outer edge portion 14b of the pattern area 14, which extends in an annular shape along the outer edge of the cover 40. The light-shielding portion 45 corresponds to the background area 15 of the design surface 13a, excluding the pattern area 14. The luminous emblem 13 is configured so that the pattern area 14 is visible from the front when the light source unit 20 is not illuminated.

[0044] <Reflective material 50> As shown in Figures 2 and 3, the reflective member 50 is disc-shaped in plan view and is provided between the cover 40 and the housing 30. The reflective member 50 covers the light source unit 20 from the front when the light source unit 20 is attached to the through hole 35.

[0045] The reflective member 50 is formed from a resin material in which white light-diffusing particles are dispersed, and is white overall. For example, ABS resin can be used as the resin material. For example, metal oxides such as titanium dioxide and zinc oxide can be used as the light-diffusing material.

[0046] The reflective member 50 has a protrusion 51 and an extended portion 53 that extends outward from the protrusion 51 integrally formed thereon. The protrusion 51 is conical in shape with axis A as its center, and protrudes toward the light source unit 20 when the light source unit 20 is attached to the through hole 35. In other words, the protrusion 51 faces the light source unit 20 in the front-rear direction L.

[0047] The protrusion 51 has an inclined surface 52 that is inclined with respect to axis A. The extended portion 53 has a projection 54 that protrudes to the rear and a hole 55 that penetrates the extended portion 53 integrally formed thereon.

[0048] In this embodiment, the protruding portion 54 is provided below the convex portion 51 in the vertical direction Z. The protruding portion 54 has an opposing surface 54a that faces the inclined surface 52 in the vertical direction Z, which is an orthogonal direction perpendicular to the front-rear direction L. The opposing surface 54a is inclined so that it approaches the convex portion 51 in the vertical direction Z as it moves towards the rear. In this embodiment, the vertical direction Z corresponds to an orthogonal direction perpendicular to the axial direction of the optical axis according to the present invention.

[0049] The hole 55 is located between the convex portion 51 and the protruding portion 54 in the vertical direction Z. The protruding portion 54 extends in a bent manner from the edge of the extended portion 53 that constitutes the hole 55. As shown in Figure 5, the reflective member 50 is configured to reflect light that has been reflected by the inclined surface 52 and incident on the opposing surface 54a of the protruding portion 54, through the hole 55 toward the first exposed portion 42 and the transparent portion 46.

[0050] Next, the operation of this embodiment will be described. As shown in Figure 2, the worker inserts the case 21 of the light source unit 20 into the through hole 35 from the rear in the first position in order to assemble the light source unit 20 into the housing 30. At this time, the notch 35b allows the claw portion 24 to pass through. This allows the case 21 to pass through the through hole 35.

[0051] As shown in Figure 3, as the case 21 is inserted into the through hole 35, the sealing member 26 elastically deforms by pressing against both the portion of the bottom wall 32 that constitutes the through hole 35 and the base portion 22. This seals the space between the through hole 35 and the case 21 of the light source unit 20.

[0052] Subsequently, the light source unit 20 is rotated from the first position shown in Figure 2 to a second position (see Figure 3) by a predetermined angle around axis A. At this time, the restricting edge 35a and the claw portion 24 are in positions that overlap each other in the front-rear direction L. Therefore, the restricting edge 35a and the claw portion 24 prevent the case 21 from coming out of the through hole 35 toward the rear. As a result, the light source unit 20 is assembled into the housing 30 with the space between the through hole 35 and the light source unit 20 sealed (end of operation 1).

[0053] Furthermore, if a malfunction occurs in the light-emitting element or the circuit board on which the light-emitting element is mounted, requiring replacement of the light source unit 20, the worker performs the reverse operation of operation 1 described above. This removes the light source unit 20 from the through-hole 35 of the housing 30.

[0054] Next, the effects of this embodiment will be described. (1) The housing 30 has a through hole 35 that penetrates the wall portion 30A and into which the light source unit 20 is detachably attached. When the light source unit 20 is attached to the through hole 35, a sealed space S is formed by the light source unit 20, the housing 30, and the cover 40, which is sealed from the outside.

[0055] This configuration produces the effects described above. As a result, the light source unit 20 can be removed from the through-hole 35 of the housing 30. Furthermore, by reattaching the light source unit 20 to the through-hole 35 and transmitting light from the light source unit 20 through the transmissive section 46, the pattern area 14 can be illuminated and displayed facing forward of the vehicle 10.

[0056] If the light source unit 20 is simply attached to the through hole 35, there is a risk that water droplets may enter the inside of the housing 30 through the gap between the portion of the wall 30A of the housing 30 that constitutes the through hole 35 and the light source unit 20. In this respect, with the above configuration, when the light source unit 20 is attached to the through hole 35, a sealed space S is formed by the light source unit 20, the housing 30, and the cover 40, which are sealed from the outside. Therefore, the entry of water droplets into the housing 30 is suppressed. Thus, the light source unit 20 can be easily replaced while maintaining watertight performance.

[0057] (2) Between the cover 40 and the housing 30, a reflective member 50 is provided that covers the light source unit 20 from the front and reflects light. When the light source unit 20 is not illuminated, it may be visible from the front of the vehicle 10 through the translucent portion 46. In this case, the appearance of the luminous emblem 13 is diminished. In this regard, with the above configuration, the light source unit 20 is covered by the reflective member 50 from the front. As a result, the light source unit 20 is less visible from the front of the vehicle 10 through the translucent portion 46. Therefore, the deterioration of the appearance of the luminous emblem 13 can be suppressed.

[0058] (3) The reflective member 50 is provided with a convex portion 51 that protrudes toward the light source unit 20 at a position facing the light source unit 20 in the front-rear direction L and has an inclined surface 52 that is inclined with respect to the axis A. The inner surface 30a of the housing 30 is configured to reflect light toward the cover 40.

[0059] If a member is simply provided to cover the light source unit 20 from the front, the light from the light source unit 20 will be blocked by the member, making it difficult to efficiently transmit the light to the transparent portion 46. In this regard, with the above configuration, as shown in Figure 5, the light emitted from the light source unit 20 is reflected by the reflective member 50. Here, the reflective member 50 is provided with a convex portion 51 having an inclined surface 52 at a position facing the light source unit 20 in the front-rear direction L. Therefore, the light is reflected by the inclined surface 52 and diffused around the convex portion 51 towards the outer circumference of the convex portion 51. The diffused light is then reflected once or multiple times between the inner surface 30a of the housing 30 and the reflective member 50 before being reflected towards the cover 40. The light that thus enters the cover 40 passes through the transparent portion 46 and is irradiated toward the front of the vehicle 10. That is, the pattern area 14 is illuminated toward the front of the vehicle 10. Therefore, even if a member is provided to cover the light source unit 20 from the front, light from the light source unit 20 can be efficiently transmitted to the transparent section 46.

[0060] (4) The reflective member 50 is provided on the outer circumference of the convex portion 51 and includes a projection 54 having an opposing surface 54a that faces the inclined surface 52 in the vertical direction Z, and a hole 55 provided between the convex portion 51 and the projection 54.

[0061] With this configuration, some of the light reflected by the inclined surface 52 of the convex portion 51 is incident on the opposing surface 54a of the protruding portion 54. The light incident on the opposing surface 54a is reflected through the hole 55 toward the transmissive portion 46. Therefore, light from the light source unit 20 can be transmitted to the transmissive portion 46 more efficiently.

[0062] (5) The transparent portion 46 is provided in the central and outer edges of the cover 40. The wall portion 30A comprises a bottom wall 32 having a through hole 35, a side wall 34 forming an opening 31, and a connecting wall 33 connecting the bottom wall 32 and the side wall 34. The connecting surface 33a is inclined with respect to axis A. The reflective member 50 is configured to reflect light that has been reflected by the inclined surface 52 and incident on the opposing surface 54a of the protrusion 54, through the hole 55 toward the transparent portion 46 in the central part. The housing 30 is configured to reflect light that has been reflected by the inclined surface 52 and incident on the connecting surface 33a toward the transparent portion 46 at the outer edge.

[0063] With this configuration, as shown in Figure 5, a portion of the light reflected by the inclined surface 52 of the protrusion 51 enters the opposing surface 54a of the projection 54. The light that enters the opposing surface 54a is reflected through the hole 55 toward the transparent portion 46 provided in the center of the cover 40. In addition, a portion of the light reflected by the inclined surface 52 of the protrusion 51 enters the connecting surface 33a of the housing 30. The light that enters the connecting surface 33a is reflected toward the front of the connecting surface 33a, i.e., toward the transparent portion 46 provided on the outer edge of the cover 40. The light reflected toward the transparent portion 46 of the cover 40 in this way is uniformly transmitted through the transparent portion 46 via the first exposed portion 42 and the second exposed portion 43, and is irradiated toward the front of the vehicle 10. Therefore, light from the light source unit 20 can be uniformly transmitted through the transparent portion 46 of the cover 40.

[0064] (6) The reflective member 50 and the housing 30 are white in color so as to reflect light. With this configuration, the reflecting member 50 and the housing 30 can increase the reflection efficiency of light from the light source unit 20. Therefore, light from the light source unit 20 can be transmitted to the transmissive section 46 more efficiently.

[0065] <Example of changes> This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically.

[0066] The reflective member 50 is not limited to being formed from a resin material in which white light-diffusing particles are dispersed, as illustrated in this embodiment. The reflective member 50 may be formed, for example, by applying a coating film in which white light-diffusing particles are dispersed to the surface of a substrate made of a resin material.

[0067] The reflective member 50 is not limited to being made of a resin material, but may also be made of a metal material. The housing 30 is not limited to being formed from a resin material in which white light-diffusing particles are dispersed, as illustrated in this embodiment. For example, it may be formed by applying a coating film in which white light-diffusing particles are dispersed to the inner surface of a wall made of resin material.

[0068] The housing 30 and the reflective member 50 do not have to be white. The light-shielding portion 45 may be formed entirely from a mixed material obtained by mixing a resin material such as PC resin with a black pigment such as carbon black. Alternatively, it may be formed by applying a light-shielding coating or plating to the surface of a base material formed entirely from a resin material such as PC resin or ABS resin.

[0069] The connecting surface 33a is not limited to being inclined with respect to axis A, but may also be a concave surface that curves with respect to axis A, for example. The protruding portion 54 and the hole portion 55 are not limited to being located below the convex portion 51 in the vertical direction Z as illustrated in this embodiment, and their arrangement may be changed as appropriate. In that case, it is sufficient that the light incident on the opposing surface 54a is reflected through the hole portion 55 toward the first exposed portion 42 and the transmissive portion 46.
