Summary of the Invention

Problems to be Solved by the Invention

[0004] In such a movable-side lamp, when the pair of side wall parts of the outer lens are formed so as to approach each other as they extend in the lamp chamber direction, the inner lens may interfere with the side wall parts of the outer lens when the inner lens is attached to the outer lens from the back of the outer lens. In order to prevent such interference, it was necessary to make the longitudinal dimension of the inner lens shorter than the dimension between the pair of side wall parts of the outer lens.

[0005] By the way, when a resin part such as an extension is larger than the opening of the outer lens, it is difficult to arrange the resin part inside the outer lens. Also, when a force is applied to the resin part so as to bend it, it is difficult to perform the operation of arranging the resin part at the target position.

[Figure 8] Figure 8 is a top view of the outer lens and inner lens, showing how the inner lens is inserted into the outer lens. [Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described below with reference to the drawings. For the sake of clarity, configurations having the same reference numerals as those already described will be omitted from the description of the embodiments.

[0012] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, arrow U indicates the upward direction of the illustrated structure. Arrow D indicates the downward direction of the illustrated structure. Arrow F indicates the forward direction of the illustrated structure. Arrow B indicates the backward direction of the illustrated structure. Arrow R indicates the rightward direction of the illustrated structure. Arrow L indicates the leftward direction of the illustrated structure. These directions are relative directions set for the vehicle lamp 1 shown in FIG. 1, and the irradiation direction of the light of the vehicle lamp 1 is taken as the forward direction.

[0013] FIG. 1 is an exploded perspective view of the vehicle lamp 1 according to the present embodiment. As shown in FIG. 1, the vehicle lamp 1 includes a housing 10, a reflector 20, an inner lens 30, an extension 40 (resin part), an outer lens 50, and a light source unit 60. The illustrated vehicle lamp 1 functions as a DRL (Daytime Running Lamp) and is used together with other high beam units, low beam units, etc. Further, the vehicle lamp 1 of the present disclosure as a DRL may be arranged inside a common casing with other high beam units and low beam units and may be configured to be mounted on the vehicle together with the casing.

[0014] The illustrated vehicle lamp 1 has an elongated shape in the left - right direction. The housing 10 is a component formed of a non - light - transmissive resin. The housing 10 is open at the front. The housing 10 forms a lamp chamber together with the outer lens 50. The reflector 20, the inner lens 30, the extension 40, and the light source unit 60 are arranged inside the lamp chamber.

[0015] The outer lens 50 transmits the light emitted from the light source unit 60 to the front of the lamp. The outer lens 50 is attached to the housing 10 so as to close the opening of the housing 10.

[0016] The light source unit 60 is provided at the left and right ends of the housing 10. The light source unit 60 is provided respectively to the left and right of the inner lens 30. The light source unit 60 causes light to be incident on each of the left and right ends of the inner lens 30 in the left - right direction.

[0017] The inner lens 30 is a component formed of a translucent resin that extends in the left - right direction. The inner lens 30 emits light forward and backward while guiding the light emitted from the light source unit 60 in the left - right direction.

[0018] The inner lens 30 has a first main plane portion 31 that extends in the left - right and up - down directions, a first contact piece 32, and a second contact piece 33. The first contact piece 32 and the second contact piece 33 are provided at a plurality of locations along the left - right direction respectively. The first main plane portion 31 is a flat plane whose dimension in the left - right direction is longer than the dimension in the up - down direction. Thus, the inner lens 30 can bend such that the left and right ends are displaced in the front - rear direction respectively.

[0019] The reflector 20 is a member that extends in the left - right direction. The reflector 20 is provided behind the inner lens 30. The reflector 20 has a reflecting surface that extends in the left - right and up - down directions. The reflector 20 reflects the light emitted rearward from the inner lens 30 forward.

[0020] The extension 40 is a component formed of an opaque resin that extends in the left - right direction. The extension 40 is a component for preventing at least a part of the lamp chamber from being seen from the front of the lamp fixture. The illustrated extension 40 covers a part of the inner lens 30 so that a part of the inner lens 30 is not visible from the outside. The extension 40 is provided in front of the inner lens 30 and behind the outer lens 50.

[0021] The extension 40 comprises a second main planar portion 41 extending in the left-right and front-back directions, a third contact piece 42, and a screw-fastening piece 43. The third contact piece 42 and the screw-fastening piece 43 are provided at multiple locations along the left-right direction. The second main planar portion 41 is a flattened plane whose left-right dimension is longer than its front-back dimension. This allows the extension 40 to flex so that its left-right ends are displaced in the up-down direction.

[0022] Next, the outer lens 50, extension 40, and inner lens 30 will be described in detail using Figure 2. Figure 2 is a longitudinal cross-sectional view of the vehicle light fixture 1. As shown in Figure 2, the outer lens 50 has an opaque portion 51 made of non-transparent resin and a transparent portion 52 made of translucent resin. The transparent portion 52 is located outside (front of) the opaque portion 51. The opaque portion 51 has a window portion 53. The transparent portion 52 blocks at least the window portion 53.

[0023] Each outer lens 50 has a first abutment 54, a second abutment 55, and a third abutment 56, all of which have flat rear surfaces. The first abutment 54 comprises a first abutment surface 54a and a first rib 54b. The second abutment 55 comprises a second abutment surface 55a and a second rib 55b. The second abutment 55 is located further rear than the first abutment 54. The second rib 55b extends further rear than the first rib 54b.

[0024] The third contact piece 42 of the extension 40 is a portion that extends downward from a part of the rear end of the second main planar portion 41. The third contact piece 42 abuts against the first abutment portion 54 of the outer lens 50. This restricts the position of the extension 40 in the front-rear direction relative to the outer lens 50. Although not shown in Figure 2, the screw fastening piece 43 is also a portion that extends downward from a part of the rear end of the second main planar portion 41, similar to the third contact piece 42. The screw fastening piece 43 also abuts against the outer lens 50.

[0025] The third contact piece 42 has a through hole 44 that penetrates in the front-rear direction. The first rib 54b of the outer lens 50 is inserted into the through hole 44 of the third contact piece 42. This restricts the position of the extension 40 in the left-right and up-down directions relative to the outer lens 50.

[0026] The first main flat portion 31 of the inner lens 30 is positioned to face the window portion 53 of the outer lens 50. The first contact piece 32 of the inner lens 30 is a portion that extends upward from a part of the upper end of the first main flat portion 31. The second contact piece 33 is a portion that extends rearward from a part of the lower end of the first main flat portion 31, bends, and extends downward. The first contact piece 32 and the second contact piece 33 each have alignment holes 32a and 33a that penetrate in the front-rear direction.

[0027] The first contact piece 32 of the inner lens 30 abuts against the third abutment portion 56 of the outer lens 50. Also, the second contact piece 33 of the inner lens 30 abuts against the second abutment portion 55 of the outer lens 50. As a result, the position of the inner lens 30 in the front-to-back direction is restricted relative to the outer lens 50. The third rib 56b of the third abutment portion 56 of the outer lens 50 is inserted into the alignment hole 32a of the first contact piece 32 of the inner lens 30. The second rib 55b of the outer lens 50 is inserted into the alignment hole 33a of the second contact piece 33 of the inner lens 30. As a result, the position of the inner lens 30 in the left-to-right and up-to-down directions is restricted relative to the outer lens 50.

[0028] Incidentally, in the vehicle light fixture 1 of this embodiment, as shown in Figure 1, the outer lens 50 has a bowl shape. The outer lens 50 comprises a front portion 57 and a left side portion 58L and a right side portion 58R extending rearward from the front portion 57. The left side portion 58L is inclined to the right toward the rear. The right side portion 58R is inclined to the left toward the rear. Therefore, the outer lens 50 has an internal housing space S (see Figure 2) that is wide in the left-right direction toward the front and narrow in the left-right direction toward the rear.

[0029] Figure 3 shows the outer lens 50, the inner lens 30 and extension 40 housed in the housing space S, and a rear view of the outer lens 50. Figure 2 is a cross-sectional view taken along the line II-II in Figure 3. The outer lens 50 has an opening 59 that opens towards the rear. Here, the left-right length (length along the long axis) of the opening 59 is called the opening length L1, the left-right length of the extension 40 is called the resin length L2, the left-right length of the inner lens 30 is called the lens length L3, and the maximum left-right length of the housing space S of the outer lens 50 is called the housing length L4.

[0030] In the vehicle light fixture 1 of this embodiment, the opening length L1, which is the length in the longitudinal direction of the opening 59 of the outer lens 50, is shorter than the housing length L4, which is the length in the longitudinal direction of the housing space S of the outer lens 50. Also, the resin length L2, which is the length in the longitudinal direction of the extension 40 (resin part), is shorter than the housing length L4 and longer than the opening length L1. In this embodiment, the lens length L3 of the inner lens 30 is also shorter than the housing length L4 and longer than the opening length L1.

[0031] Due to these dimensional relationships, the extension 40 is longer than the opening 59, making it difficult to fit it into the storage space S as is. Therefore, in this disclosure, the vehicle light fixture 1 is manufactured by inserting the extension 40 into the outer lens 50 using the manufacturing method described below.

[0032] Figure 4 is a rear view of the process of inserting the extension 40 into the outer lens 50. The front of the page is the rear, and the back of the page is the front. As mentioned above, an opening 59 is provided at the rear of the outer lens 50. The extension 40 can also bend so that both ends in the left-right direction are displaced in the up-down direction. First, the worker bends the extension 40 on the outside of the outer lens 50 so that both ends in the left-right direction are displaced above the center so that the extension 40 can pass through the opening 59. In this state, the extension 40 is passed through the opening 59.

[0033] After passing the extension 40 over the outer lens 50 in this bent state, the worker inserts it while positioning it using the third contact piece 42 of the extension 40 and the first abutment portion 54 of the outer lens 50. Figure 5 is an enlarged view showing the third contact piece 42 of the extension 40 and the first abutment portion 54 of the outer lens 50.

[0034] As shown in Figure 5, the third contact piece 42 of the extension 40 is aligned with the first abutment portion 54 of the outer lens 50, and the extension 40 is then moved forward to insert the first rib 54b of the outer lens 50 into the through hole 44 of the third contact piece 42 and insert it to a predetermined position in the housing space S. Once the extension 40 has been inserted forward until the third contact piece 42 of the extension 40 abuts against the first abutment surface 54a of the outer lens 50, the worker releases the extension 40 to release its flex. In other words, the extension 40 (resin part) is flexed, and the third contact piece 42 (first positioning portion) of the extension 40 is in contact with the first contact piece 32 (second positioning portion) of the outer lens 50 while the extension 40 is inserted into the housing space S of the outer lens 50.

[0035] As described above, according to this disclosure, the extension 40 (resin part) can be inserted into the housing space S of the outer lens 50 while being positioned, making it easy to place the extension 40 in the desired position on the outer lens 50. Although it is difficult to make fine adjustments to the position of the extension 40 because the worker is bending the extension 40, it can be easily placed in the desired position by moving the extension 40 so that the third contact piece 42 searches for the first rib 54b. For this reason, even though there is a work step of bending the extension 40, it is easy to place the extension 40 in the desired position.

[0036] Alternatively, after positioning the extension 40 in the desired location within the outer lens 50, the extension 40 may be fixed in the front-to-back position to the outer lens 50 by screwing a screw into the screw fastening piece 43 from the rear up to the outer lens 50.

[0037] Furthermore, in this embodiment, the position of the extension 40 in the intersecting left-right direction (first direction) and up-down direction (second direction) is determined by the contact between the through hole 44 (first positioning part) of the third contact piece 42 of the extension 40 and the first rib 54b (second positioning part) of the first abutment part 54 of the outer lens 50. In addition, the position in the front-rear direction (third direction) is determined by screwing the extension 40 to the outer lens 50. In this way, the position of the extension 40 on the outer lens 50 can be determined.

[0038] Figure 6 is a perspective view of the first abutment portion 54 of the outer lens 50, viewed from diagonally above and behind. As shown in Figure 6, the rear surface of the outer lens 50 is provided with a recess 70 that is recessed toward the front, and the first abutment portion 54 is provided in the recess 70. The recess 70 has a rear surface 71 and a pair of side surfaces 72. The rear surface 71 of the recess 70 is provided with a first rib 54b that is elongated in the left-right direction and protrudes toward the rear. The rear surface 71 of the recess 70 is further provided with a first abutment surface 54a that is elongated in the up-down direction and protrudes toward the rear. This first abutment surface 54a has a shorter protruding length than the first rib 54b, and the first abutment surface 54a is located in front of the rear end of the first rib 54b. The side surfaces of the recess 70 are composed of a pair of tapered portions 73 that are provided so as to sandwich the first rib 54b. The pair of tapered portions 73 are inclined so that the distance between them widens toward the rear.

[0039] Figure 7 is a perspective view showing the third contact piece 42 of the extension 40 abutting against the first abutment portion 54 of the outer lens 50. As shown in Figure 7, the third contact piece 42 is a plate-shaped portion that includes a portion extending downward from the rear end of the second main planar portion 41. A through-hole 44 is provided in this third contact piece 42, which penetrates in the front-to-back direction and extends in the left-to-right direction.

[0040] When an operator attempts to align the third contact piece 42 with the first abutment portion 54, the tapered portion 73 of the outer lens 50 guides the third contact piece 42 of the extension 40, and the first rib 54b is guided into the through hole 44. In other words, the tapered portion 73 is inclined to contact the side surface of the third contact piece 42 of the extension 40 and guide the through hole 44 (slit) toward the first rib 54b of the outer lens 50.

[0041] In other words, in this embodiment, as shown in Figures 2 and 6, The first positioning portion (third contact piece 42) of the extension 40 is a plate-shaped portion with a slit (through hole 44) provided therein. The second positioning portion (first abutment portion 54) of the outer lens 50 is, A rib portion (first rib 54b) that can be inserted into the slit, It has a pair of tapered portions 73 provided so as to sandwich the rib portion, The tapered portion 73 is inclined to contact the side surface of the plate-like portion and guide the slit of the first positioning portion toward the rib portion.

[0042] Furthermore, the first abutment surface 54a of the first abutment portion 54 of the outer lens 50 makes surface contact with the third abutment piece 42 of the extension 40. As a result, the first abutment surface 54a prevents the extension 40 from advancing any further forward (in the height direction of the rib portion). In other words, in the vehicle lighting device 1 of this embodiment, The second positioning portion (first abutment portion 54) may further have a surface contact portion (first abutment surface 54a) that contacts the plate-shaped portion (third abutment piece 42) of the extension 40 to restrict the position of the extension 40 in the height direction of the rib portion.

[0043] Figure 8 is a top view of the outer lens 50 and inner lens 30, showing how the inner lens 30 is inserted into the outer lens 50. After positioning the extension 40 on the outer lens 50 as described above, the inner lens 30 may be positioned on the outer lens 50 as follows.

[0044] As shown in Figure 3, the lens length L3 of the inner lens 30 is also longer than the opening length L1 of the outer lens 50. Therefore, the inner lens 30 is inserted into the outer lens 50 while being bent. As mentioned above, the outer lens 50 bends so that both ends in the left-right direction are displaced in the front-rear direction relative to the center. Therefore, as shown in Figure 8, the worker bends the inner lens 30 so that both ends in the left-right direction are displaced forward of the center on the outside (rear) of the outer lens 50.

[0045] In this state, the worker passes the inner lens 30 through the opening of the outer lens 50 to release the deflection. Then, the second contact piece 33 of the inner lens 30 is brought into contact with the second abutment portion 55 of the outer lens 50 to perform positioning. The positioning by the second contact piece 33 and the second abutment portion 55 is the same as the positioning by the third contact piece 42 of the extension 40 and the first abutment portion 54 of the outer lens 50 described above, so the explanation is omitted.

[0046] As shown in Figure 2, the first contact piece 32 of the inner lens 30 abuts against the third abutment portion 56 of the outer lens 50. The first contact piece 32 and the third abutment portion 56 are located above the window portion 53. The inner lens 30 abuts against the outer lens 50 both above and below the first main plane portion 31. Since the inner lens 30 is a member that is longer in the vertical direction than the extension 40, it is preferable that it abuts against the outer lens 50 at two positions separated in the vertical direction in this manner. Furthermore, the first contact piece 32 of the inner lens 30 may be fixed to the third abutment portion 56 of the outer lens 50 by heat crimping, and the second contact piece 33 of the inner lens 30 may also be fixed to the second abutment portion 55 of the outer lens 50 by heat crimping.

[0047] The first main planar portion 31 of the inner lens 30 often forms a lens surface and is often configured as a portion that extends in the left-right and up-down directions. Therefore, the inner lens 30 flexes in the front-back direction. In contrast, the extension 40 is configured to flex in the up-down direction. Since the flexing of a member tends to result in insufficient rigidity in that direction, in this embodiment, the extension 40 and the inner lens 30 are combined in such a way that they complement each other's rigidity. It is preferable that even if the flexing directions of the extension 40 and the inner lens 30 are different, the positioning direction (the direction in which the rib portion extends) is the same. This is because it makes insertion work and fixing work such as screwing and heat riveting easier.

[0048] While embodiments of this disclosure have been described above, it goes without saying that the technical scope of this disclosure should not be interpreted restrictively by the description of these embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications to the embodiments are possible within the scope of the invention described in the claims. The technical scope of this disclosure should be determined based on the scope of the invention described in the claims and the scope of its equivalents.

[0049] The shapes of the extension 40 and outer lens 50 are not limited to those shown in this disclosure. It goes without saying that the number of contact pieces and abutment portions is not limited to those shown. [Explanation of Symbols]
