Summary of the Invention

Problems to be Solved by the Invention

[0004] Here, in the above vehicle lighting device, in the second light emitting unit, for example, by reducing the number of LEDs, it is possible to contribute to the reduction of the number of parts. However, when the number of LEDs in the second light emitting unit is reduced, the illumination range of the light irradiated from the second light source LED becomes narrow, and there is a possibility that illumination unevenness or the like occurs in the second lens. In this case, by arranging the second light source LED on the back side (the other side) in the depth direction with respect to the second lens and setting the distance in the depth direction between the second light source LED and the second lens to be long, the diffusion range of the light expands, and the illumination unevenness can be improved. However, in this case, the dimension in the depth direction in the second light emitting unit becomes large, which may interfere with the layout of the power receiving and supplying unit or the like.

[0005] Taking the above facts into consideration, the present invention provides a vehicle lighting device that can suppress an increase in size in the depth direction. [Means for solving the problem]

[0006] One or more embodiments of the present invention are vehicle lighting devices for illuminating an energy receiving section of a vehicle, comprising: a light source that emits emitted light toward one side in the depth direction of the energy receiving section; and a light guide lens provided on one side of the light source in the depth direction, wherein the light guide lens comprises: a first lens portion provided on one side of the light source in the depth direction and into which light emitted from the light source is received; and a second lens portion that extends around the energy receiving section when viewed from the depth direction and includes an illumination section that illuminates the energy receiving section, and guides the light received by the first lens portion to the illumination section, wherein in a cross-sectional view taken from the direction of extension of the illumination section, the first lens portion extends in the depth direction and the second lens portion extends in a direction intersecting the direction of extension of the first lens portion. [Effects of the Invention]

[0007] According to one or more embodiments of the present invention, it is possible to suppress an increase in body size in the depth direction. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] The vehicle lighting device 10 according to this embodiment will be described below with reference to the drawings. As shown in Figure 1, the vehicle lighting device 10 is applied to the energy receiving unit 50 of a vehicle (automobile). The arrows UP, FR, and RH shown in the drawings as appropriate indicate the upper, front, and right sides of the vehicle lighting device 10 and the energy receiving unit 50, respectively. The front-to-back direction of the energy receiving unit 50 coincides with the depth direction of the energy receiving unit 50.

[0010] As shown in Figures 1 to 3, the energy receiving unit 50 is located on the side of the rear of the vehicle. The energy receiving unit 50 has a base 52, which is located inside a panel opening (not shown) formed in the outer panel of the vehicle. The base 52 is provided with a lid (not shown) that opens and closes the panel opening. By opening the lid, the base 52 is exposed to the outside of the vehicle through the panel opening.

[0011] The base 52 is formed in a concave shape that opens to the front, and the thickness direction of the bottom wall of the base 52 coincides with the front-to-rear direction of the energy receiving section 50. An exposed hole 52A is formed through the bottom wall of the base 52, and the exposed hole 52A is formed in a substantially rectangular shape with the left-to-right direction as its longitudinal direction. The energy receiving section 50 has a charging inlet 54 (which is broadly understood as an element of the receiving section). The charging inlet 54 is located on the rear side of the bottom wall of the base 52 and is exposed to the front through the exposed hole 52A. Energy is supplied to the vehicle when a charger connector (not shown) is connected to the charging inlet 54.

[0012] (Regarding the vehicle lighting device 10) As shown in Figures 1 to 4, the vehicle lighting device 10 is configured as a lighting device that illuminates the area around the charging inlet 54. The vehicle lighting device 10 includes a cover 20, a substrate 30, and a light guide lens 40.

[0013] (Cover 20) The cover 20 is made of a material that does not transmit light (in this embodiment, a resin material) and is positioned on the rear side of the bottom wall of the base 52. The cover 20 is formed in a substantially rectangular ring shape when viewed from the front-rear direction, and in a cross-sectional view when viewed from the circumferential direction, it is formed in a concave shape that opens to the front. Specifically, the cover 20 is composed of a bottom wall 21 with the front-rear direction as the thickness direction, an outer circumferential wall 22 extending forward from the outer periphery of the bottom wall 21, and an inner circumferential wall 23 extending forward from the inner circumferential part of the bottom wall 21. Fixing pieces 24 (see Figure 4) are provided at the four corners of the outer circumferential wall 22. The fixing pieces 24 are fixed to the vehicle by fixing screws (not shown).

[0014] A first fitting groove 22A, which opens to the front, is formed on the front end surface (tip surface) of the outer peripheral wall 22 in the middle portion in the thickness direction. The first fitting groove 22A extends along the circumferential direction of the outer peripheral wall 22 and is formed around the entire circumference of the outer peripheral wall 22. A second fitting groove 23A, which opens to the front, is formed on the front end surface (tip surface) of the inner peripheral wall 23 in the middle portion in the thickness direction. The second fitting groove 23A extends along the circumferential direction of the inner peripheral wall 23 and is formed around the entire circumference of the inner peripheral wall 23. The portion of the inner peripheral wall 23 inside the second fitting groove 23A at the front end (the portion opposite to the outer peripheral wall 22 relative to the second fitting groove 23A) protrudes forward from the second fitting groove 23A at the front end of the inner peripheral wall 23.

[0015] A cover-side flange portion 25 is formed at the tip of the inner peripheral wall 23, protruding toward the exposed hole 52A side (radially inward) of the base 52. The cover-side flange portion 25 extends along the circumferential direction of the inner peripheral wall 23 and is formed around the entire circumference of the inner peripheral wall 23. As a result, a cover hole 25A is formed on the inside of the cover-side flange portion 25. The cover hole 25A is similar in shape to the exposed hole 52A, and the size of the cover hole 25A is set so that, when viewed from the front, the cover hole 25A is positioned outside the exposed hole 52A.

[0016] A sealing member 26 is integrally provided on the edge of the cover hole 25A in the cover-side flange portion 25. The sealing member 26 is made of an elastic material such as rubber or elastomer. The sealing member 26 is formed in a substantially L-shape in cross-section so as to cover the rear surface of the cover-side flange portion 25 and the inner circumferential surface of the cover hole 25A. The sealing member 26 extends in the circumferential direction of the cover hole 25A and is formed around the entire circumference of the cover hole 25A. The sealing member 26 is provided with a sealing portion 26A that protrudes to the rear. The sealing portion 26A extends around the entire circumference of the sealing member 26. The tip of the sealing portion 26A abuts against the charging inlet 54 and undergoes elastic deformation (compression deformation). As a result, the space between the charging inlet 54 and the cover-side flange portion 25 is sealed by the sealing member 26.

[0017] (Regarding the substrate 30) The substrate 30 has its front - rear direction as the plate - thickness direction and is formed in a substantially rectangular - annular shape. The substrate 30 is housed inside the cover 20 and is fixed to the cover 20 at a position not shown. A plurality of light sources 32 are provided on the outer peripheral portion of the front surface of the substrate 30, and the light sources 32 are LEDs. The light sources 32 are arranged side by side at a predetermined interval in the circumferential direction of the substrate 30. The light sources 32 are configured to emit the emitted light forward.

[0018] (Regarding the light - guiding lens 40) As also shown in FIG. 5, the light - guiding lens 40 is made of a resin material capable of transmitting light. The light - guiding lens 40 guides the light emitted by the light source 32 around the charging inlet 54 to illuminate the periphery of the charging inlet 54. The light - guiding lens 40 includes a light - emitting - side lens portion 41 as the second lens portion, a light - incident - side lens portion 42 as the first lens portion, and a reflecting portion 43.

[0019] The light - emitting - side lens portion 41 is formed in a substantially rectangular - plate shape with its front - rear direction as the plate - thickness direction. The outer shape of the light - emitting - side lens portion 41 is formed to be similar to the outer shape of the outer peripheral wall 22 of the cover 20. The light - emitting - side lens portion 41 is disposed between the cover 20 and the bottom wall of the base 52, and the size of the light - emitting - side lens portion 41 is set such that, when viewed from the front, the light - emitting - side lens portion 41 is disposed inside the outer peripheral wall 22 of the cover 20. A lens hole 41A is formed through the light - emitting - side lens portion 41. The lens hole 41A is similar in shape to the exposed hole 52A of the base 52, and the size of the lens hole 41A is set such that, when viewed from the front, the edge portion of the lens hole 41A is exposed from the exposed hole 52A. And the edge portion of the lens hole 41A exposed from the exposed hole 52A serves as the illumination portion 41B. Thereby, when viewed from the front, the illumination portion 41B is arranged to surround the charging inlet 54.

[0020] The light-receiving lens portion 42 is formed in a substantially rectangular cylindrical shape with the front-to-back direction as its axis, and extends to the rear from the outer circumference of the light-emitting lens portion 41. That is, in a cross-sectional view taken from the extending direction of the illumination portion 41B (circumferential direction of the lens hole 41A), the extending direction of the light-emitting lens portion 41 and the extending direction of the light-receiving lens portion 42 intersect. The rear part of the light-receiving lens portion 42 is located inside the cover 20 and adjacent to the front side of the substrate 30. Specifically, the light-receiving lens portion 42 is positioned in front of the light source 32. Multiple recesses 42A are formed on the rear end surface of the light-receiving lens portion 42 at positions corresponding to the light source 32. The recesses 42A are formed in a concave shape that opens to the rear, and the light source 32 is positioned within the recesses 42A. As a result, light emitted from the light source 32 to the front is received by the light-receiving lens portion 42.

[0021] Furthermore, in a cross-sectional view of the light-receiving lens portion 42 from the circumferential direction, the length of the light-emitting lens portion 41 (length in the direction perpendicular to the front-to-back direction) is set to be longer than the length of the light-receiving lens portion 42 (length in the front-to-back direction). In this embodiment, the length of the light-emitting lens portion 41 is set to be more than twice the length of the light-receiving lens portion 42.

[0022] The reflective portion 43 is formed on the outer circumferential surface of the light-emitting lens portion 41. The reflective portion 43 is an inclined surface that slopes toward the lens hole 41A side (illumination portion 41B side) as it approaches the front when viewed from the circumferential direction of the light-emitting lens portion 41, and is formed around the entire circumference of the outer circumferential portion of the light-emitting lens portion 41. As a result, the reflective portion 43 is positioned in front of the light-receiving lens portion 42. The width dimension of the reflective portion 43 is set to be larger than the width dimension (plate thickness dimension) of the light-receiving lens portion 42. Therefore, the light BM (see Figure 3) emitted from the light source 32 enters the light-receiving lens portion 42, and the light BM that enters the light-receiving lens portion 42 is reflected by the reflective portion 43 in a direction perpendicular to the front-to-back direction. Specifically, the light BM is reflected toward the illumination portion 41B side by the reflective portion 43. The light BM reflected by the reflecting section 43 is then guided by the light-emitting lens section 41 and emitted from the illumination section 41B. As a result, the area around the charging inlet 54 is illuminated by the illumination section 41B.

[0023] A lens-side flange portion 44 is integrally formed at the front end of the light-receiving lens portion 42. The lens-side flange portion 44 extends from the light-receiving lens portion 42 toward the opposite side of the lens hole 41A, extends along the circumferential direction of the light-receiving lens portion 42, and is formed around the entire circumference of the light-receiving lens portion 42. The lens-side flange portion 44 is positioned adjacent to the front side of the outer peripheral wall 22 of the cover 20. A first fitting portion 44A is integrally formed on the lens-side flange portion 44. The first fitting portion 44A protrudes to the rear from the lens-side flange portion 44, is formed as a rib extending in the circumferential direction of the lens-side flange portion 44, and is formed around the entire circumference of the lens-side flange portion 44. The first fitting portion 44A is fitted into the first fitting groove 22A of the cover 20.

[0024] A partition wall 45 is integrally formed on the rear surface of the light-emitting lens portion 41 in the portion facing the inner peripheral wall 23 of the cover 20 in the front-rear direction. The partition wall 45 is formed in a substantially rectangular frame shape that protrudes rearward from the light-emitting lens portion 41 and is positioned adjacent to the front side of the inner peripheral wall 23. A second fitting portion 45A is integrally formed on the rear end surface of the partition wall 45. The second fitting portion 45A protrudes rearward from the partition wall 45 and is formed in a rib shape that extends in the circumferential direction of the partition wall 45, and is formed around the entire circumference of the partition wall 45. The second fitting portion 45A is fitted into the second fitting groove 23A of the cover 20. As described above, the opening of the cover 20 is closed by the light guide lens 40.

[0025] (Effects and Benefits) Next, the effects and advantages of this embodiment will be described.

[0026] In the vehicle lighting device 10 configured as described above, when the light source 32 emits light, light BM is emitted from the light source 32 toward the front and enters the light-incoming lens portion 42 of the light guide lens 40. The light BM that enters the light-incoming lens portion 42 is reflected by the reflecting portion 43 in a direction perpendicular to the front-to-back direction. Specifically, the reflecting portion 43 reflects the light BM toward the lens hole 41A side of the light guide lens 40. As a result, the light BM is guided to the lighting unit 41B by the light-emitting lens portion 41. Consequently, the lighting unit 41B illuminates the area around the charging inlet 54. Therefore, for example, the position of the charging inlet 54 can be recognized by the lighting unit 41B.

[0027] Here, the light guide lens 40 of the vehicle lighting device 10 is configured to include a light-receiving lens portion 42 provided on the front side of the light source 32, and a light-emitting lens portion 41 that guides the light received by the light-receiving lens portion 42 to the illumination unit 41B. Furthermore, in a cross-sectional view taken from the extending direction of the illumination unit 41B, the light-receiving lens portion 42 extends in the front-rear direction, and the light-emitting lens portion 41 extends in a direction intersecting the front-rear direction. As a result, in a vehicle lighting device 10 having a light source 32 that emits light BM to the front, it is possible to shorten the distance between the light source 32 and the illumination unit 41B in the front-rear direction (the direction of the optical axis of the light source 32) while ensuring the optical path length of light BM in the light guide lens 40.Therefore, it is possible to suppress uneven illumination in the illumination unit 41B while suppressing an increase in the size of the vehicle lighting device 10 in the front-rear direction.

[0028] In other words, for example, if the light source 32 is placed directly behind the illumination unit 41B, the light guide lens 40 is formed in a cylindrical shape with the front-to-back direction as its axis. In such a configuration, if the distance between the light source 32 and the illumination unit 41B in the front-to-back direction is short (if the length of the light guide lens 40 in the front-to-back direction is short), the illumination range of the light BM onto the illumination unit 41B becomes narrower, and uneven illumination may occur in the illumination unit 41B. For this reason, in such a configuration, it is necessary to increase the distance between the light source 32 and the illumination unit 41B in the front-to-back direction to ensure the optical path length of the light BM in the light guide lens 40. In this case, the front-to-back length of the light guide lens 40 becomes longer, and the size of the vehicle lighting device 10 in the front-to-back direction tends to increase.

[0029] In contrast, in the vehicle lighting device 10 of this embodiment, as described above, when viewed from the extending direction of the lighting unit 41B, the light-receiving lens unit 42 extends in the front-rear direction, and the light-emitting lens unit 41 extends in a direction intersecting the front-rear direction. Therefore, while ensuring the optical path length of light BM in the light guide lens 40, the distance between the light source 32 and the lighting unit 41B in the front-rear direction can be shortened.

[0030] Furthermore, the light guide lens 40 is provided with a reflecting section 43, and the light BM that enters the light-incoming lens section 42 is reflected by the reflecting section 43 toward the illumination section 41B. As a result, the direction of the light BM from the light source 32 that is emitted toward the front is changed by the reflecting section 43, and the light BM with the changed direction can be guided toward the illumination section 41B by the light-emitting lens section 41. Therefore, the illumination section 41B can be illuminated well.

[0031] Furthermore, the light-receiving lens portion 42 extends rearward from the light-emitting lens portion 41. This further ensures the optical path length of the light BM in the light guide lens 40. In particular, in this embodiment, in a cross-sectional view seen from the circumferential direction of the light-receiving lens portion 42, the length of the light-emitting lens portion 41 is set to be longer than the length of the light-receiving lens portion 42. Therefore, the distance between the light source 32 and the illumination unit 41B in the front-to-back direction can be shortened while effectively increasing the optical path length of the light BM in the light guide lens 40.

[0032] Furthermore, the light guide lens 40 is composed of a light-emitting lens portion 41 and a light-receiving lens portion 42. The light-emitting lens portion 41 is formed in a plate shape with the front-to-back direction as the thickness direction and has a lens hole 41A formed to surround the charging inlet 54. The edge of the lens hole 41A is the illumination portion 41B. The light-receiving lens portion 42 is formed in a substantially rectangular cylindrical shape that extends to the rear from the outer circumference of the light-emitting lens portion 41. Multiple light sources 32 are arranged facing the tip of the light-receiving lens portion 42 in the front-to-back direction and are spaced apart in the circumferential direction of the light-receiving lens portion 42. As a result, the illumination portion 41B can illuminate the area around the charging inlet 54. In addition, since the optical path length of the light BM in the light guide lens 40 is secured, the illumination range of the light BM on the illumination portion 41B can be widened. Therefore, the number of light sources 32 provided on the substrate 30 can be reduced while the illumination unit 41B illuminates the area around the charging inlet 54.

[0033] Furthermore, the cover 20 is formed in a rectangular ring shape when viewed from the front, and in a concave shape that opens to the front when viewed from the circumferential direction. The substrate 30 is housed inside the cover 20, and the opening of the cover 20 is closed by the light guide lens 40. Therefore, the light guide lens 40 can also function as a lid for the cover 20. This makes it possible to ensure waterproofing and dustproofing for the substrate 30 by utilizing the light guide lens 40 to guide light from the light source 32 to the illumination unit 41B.

[0034] Furthermore, the light guide lens 40 has a lens-side flange portion 44 positioned adjacent to the front side of the outer peripheral wall 22 of the cover 20, and the lens-side flange portion 44 has a first fitting portion 44A that fits into a first fitting groove 22A formed on the front end surface of the outer peripheral wall 22. The light guide lens 40 also has a partition wall 45 that protrudes to the rear from the light-emitting lens portion 41, and the tip of the partition wall 45 has a second fitting portion 45A that fits into a second fitting groove 23A formed on the inner peripheral wall 23 of the cover 20. As a result, the joint between the light guide lens 40 and the cover 20 has a so-called labyrinth structure. Therefore, waterproof and dustproof properties for the substrate 30 can be further ensured.

[0035] Furthermore, the cover 20 has a cover-side flange portion 25, and the cover-side flange portion 25 is provided with a sealing member 26 that seals the space between the cover-side flange portion 25 and the charging inlet 54. This prevents liquids such as rainwater from entering the rear side of the base 52 from between the charging inlet 54 and the cover 20.

[0036] (Regarding modified examples of the light guide lens 40) Next, modified examples of the light guide lens 40 will be described using Figures 6(A)-(C) and 7(A)-(C). Figures 6(A)-(C) and 7(A)-(C) show cross-sectional views corresponding to the enlarged cross-sectional view of the left outer circumference of the light guide lens 40 in Figure 3. As shown in Figure 6(A), in Modification 1 of the light guide lens 40, the outer circumference of the light-emitting lens portion 41 is curved in a substantially arc shape toward the rear as it moves radially outward from the lens hole 41A when viewed from the circumferential direction of the lens hole 41A, and is connected to the light-receiving lens portion 42. Specifically, the outer circumference of the light-emitting lens portion 41 is formed in a substantially arc shape that is radially outward and forward from the lens hole 41A. Also, in Modification 1 of the light guide lens 40, the reflective portion 43 is omitted. In the modified example 1 of the light guide lens 40, the light BM (not shown) that enters the light-incoming lens portion 42 is reflected by the side surface of the light-emitting lens portion 41 and guided to the illumination portion 41B.

[0037] As shown in Figure 6(B), in Modification 2 of the light guide lens 40, the light-emitting lens portion 41 is inclined towards the rear as it moves radially outward from the lens hole 41A when viewed from the circumferential direction of the lens hole 41A, and is connected to the front end of the light-receiving lens portion 42. Also, in Modification 2 of the light guide lens 40, the reflective portion 43 is omitted. And, in Modification 2 of the light guide lens 40, similar to Modification 1, the light BM (not shown) that enters the light-receiving lens portion 42 is reflected by the side surface of the light-emitting lens portion 41 and guided to the illumination portion 41B.

[0038] As shown in Figure 6(C), in Modification 3 of the light guide lens 40, an intermediate lens portion 46 is provided between the light-emitting lens portion 41 and the light-receiving lens portion 42, and the light-emitting lens portion 41 and the light-receiving lens portion 42 are connected by the intermediate lens portion 46. When viewed from the circumferential direction of the lens hole 41A, the intermediate lens portion 46 is inclined towards the rear as it moves radially outward from the lens hole 41A. In Modification 3 of the light guide lens 40, the inclined surface of the intermediate lens portion 46 is a reflecting portion 43. In Modification 3 of the light guide lens 40, the light BM (not shown) that enters the light-receiving lens portion 42 is reflected by the reflecting portion 43 towards the light-emitting lens portion 41 and guided to the illumination portion 41B.

[0039] As shown in Figure 7(A), in Modification 4 of the light guide lens 40, the light-emitting lens portion 41 is inclined forward as it moves radially outward from the lens hole 41A when viewed from the circumferential direction of the lens hole 41A, and is connected to the front end of the light-receiving lens portion 42. In Modification 4 of the light guide lens 40, a reflecting portion 43 is formed at the front end of the light-receiving lens portion 42. In Modification 4 of the light guide lens 40, similar to this embodiment, the light BM (not shown) that enters the light-receiving lens portion 42 is reflected by the reflecting portion 43 and guided to the illumination portion 41B.

[0040] As shown in Figure 7(B), in Modification 5 of the light guide lens 40, the light-receiving lens portion 42 extends in a direction that inclins radially inward of the lens hole 41A as it moves from the outer circumference of the light-emitting lens portion 41 toward the rear when viewed from the circumferential direction of the lens hole 41A. In Modification 5 of the light guide lens 40, a reflecting portion 43 is formed at the front end of the light-receiving lens portion 42. In Modification 5 of the light guide lens 40, the light BM (not shown) that enters the light-receiving lens portion 42 is reflected toward the light-emitting lens portion 41 by the side surface of the light-receiving lens portion 42 and the reflecting portion 43, and guided to the illumination portion 41B.

[0041] As shown in Figure 7(C), in Modification 6 of the light guide lens 40, the light-receiving lens portion 42 extends in a direction that inclins radially outward from the lens hole 41A as it moves from the outer circumference of the light-emitting lens portion 41 toward the rear when viewed from the circumferential direction of the lens hole 41A. In Modification 6 of the light guide lens 40, the reflective portion 43 is omitted. In Modification 6 of the light guide lens 40, the light BM (not shown) that enters the light-receiving lens portion 42 is reflected by the sides of the light-receiving lens portion 42 and the light-emitting lens portion 41 and guided to the illumination portion 41B.

[0042] As described above, in the modified versions 1 to 6 of the light guide lens 40, in a cross-sectional view taken from the direction of extension of the illumination section 41B, the light-receiving lens section 42 extends in the front-to-back direction, and the light-emitting lens section 41 extends in a direction intersecting the front-to-back direction. Therefore, while ensuring the optical path length of light BM in the light guide lens 40, the distance between the light source 32 and the illumination section 41B in the front-to-back direction can be shortened. Accordingly, the modified versions 1 to 6 of the light guide lens 40 can achieve the same effects as in this embodiment.

[0043] In this invention, "the light-receiving lens portion 42 extends in the front-rear direction" also includes cases where it extends in a direction inclined with respect to the front-rear direction, as shown in modified examples 5 and 6 of the light guide lens 40.

[0044] Furthermore, the present invention is not limited to the embodiments described above, and various modifications are possible without departing from the spirit of the invention. [Explanation of Symbols]
