Description

  The present invention relates to a vehicular lamp and an assembling method thereof.

  In vehicles (automobiles), it is necessary to show other traffic (vehicles or pedestrians) to turn right or left or change course. And, as the irradiation light does not interfere with other traffic, the standard of visual recognition in terms of the color, brightness, etc. of the lamp (being able to see from all positions within the specified range) Is stipulated.

  For example, in the direction indicators provided on both sides of the vehicle, lighting can be confirmed in the daytime from a distance of 30 m, and the irradiation beam does not interfere with other traffic. Has been. Further, the direction indicator provided on both side surfaces includes a horizontal plane including a horizontal line O1 passing through the center of the direction indicator 100 ′ and orthogonal to the traveling direction of the vehicle, as shown in FIG. A vertical plane parallel to the traveling direction of the vehicle, including the plane of 15 degrees (α) above and 15 degrees (α) below, and the center of the direction indicator 100 ′, as shown in FIG. 10B. Plane O2 which is behind the center of the direction indicator 100 ′ and a plane of 5 degrees (β) outside the direction indicator 100 ′ and a plane which is 60 degrees (γ) outside the direction indicator 100 ′. It can be seen from all positions in the range surrounded by.

  By the way, since the door mirror device provided on both sides of the vehicle is at a moderate height from the road surface, it is easy to see from other traffic such as oncoming vehicles and pedestrians. Conventionally, focusing on this advantage of high visibility, a door mirror device having a turn indicator function that lights when a vehicle turns right or left or changes its course is known. An application for a vehicular lamp has been filed (see Patent Document 1).

  A vehicular lamp is mounted on a housing of a door mirror device, and includes a flexible board on which a predetermined number of light emitters (LEDs) are attached, a reflector for fixing the flexible board, and a base member for fixing the reflector. And a cover member for protecting the light emitter. In a conventional lamp, an operator pushes and attaches the light emitter of the flexible substrate into the concave groove portion of the reflector with a finger, and then attaches the reflector in this state to the base member.

Recently, the reflector has become narrower from a design point of view. For this reason, it is difficult for the operator to push the flexible substrate into the concave groove portion of the reflector with a finger. In addition, there is a problem that accurate positioning is difficult only by pushing the light-emitting body of the flexible substrate into the concave groove portion of the reflector, and it is easily displaced due to vibration of the traveling vehicle.

Thereafter, a reflector is attached to the base member so that the light emitter is exposed from an opening provided in the reflector, and then a cover member is integrally attached to the base member so as to cover the reflector. It is characterized by.

  In a conventional vehicle lamp, a flexible substrate on which a light emitter is surface-mounted is attached to a reflector, and the reflector in this state is attached to a base member. However, in the vehicular lamp according to the present invention, the flexible board on which the light emitter is surface-mounted is attached to the base member, and then the reflector is attached to the base member. That is, an attachment portion formed by projecting an end portion of the hard plate attached to the surface facing the light emitting body mounted on the flexible substrate in a direction intersecting the longitudinal direction of the flexible substrate is provided on the base member. It is attached to the mounting part. Since the portion of the base member where the mounting portion is provided is open, and there is no need to push the flexible substrate into the narrow concave groove portion of the reflector as in the prior art, the assemblability is improved and the base member Therefore, the flexible substrate can be reliably positioned. In particular, even if the width of the concave groove portion of the reflector is narrow from the viewpoint of design, the flexible substrate can be attached to the base member without hindrance. Furthermore, since the hard plate is large, the heat dissipation effect is improved and the life of the light emitter is extended.

Specifically, the attached portion includes first and second protrusions that are fixed integrally with the base member and are disposed to face each other with a predetermined gap therebetween.
The attachment portion is inserted into the gap between the first and second protrusions and is held between them.

The first or second protrusion is provided with a guide rail portion for guiding insertion of the attachment portion,
The guide rail portion may be provided so as to stand vertically or obliquely with respect to the bottom surface portion of the base member.

  Thereby, the operator can press the attachment portion of the flexible substrate against the guide rail portion and insert it into the gap between the first and second protrusions in a form of sliding obliquely, so that the attachment operation is easy.

  In addition, at least one of the first and second protrusions is elastically deformed by contacting the mounting portion inserted into the gap, and elastically restored in a state where the mounting portion is inserted into the gap. A locking portion that locks the mounting portion and prevents the mounting portion from being detached or displaced can be provided.

  When the attachment portion is inserted into the gap between the first and second protrusions, the locking portion provided on at least one of them is elastically deformed by coming into contact with the attachment portion. And this latching | locking part is elastically restored in the state in which the attachment part was inserted, and latches with an attachment part. Thereby, it is prevented that a mounting part slips out or shifts.

  Moreover, the pressing part for pressing the flexible substrate attached to the said base member toward the said base member is provided in the surface part facing the said base member in the said reflector.

  The flexible substrate attached to the base member is pressed by a pressing portion provided on the reflector. Thereby, a flexible substrate is hold | maintained more reliably at a base member.

It is. The housing 2 has a vessel shape (conical container shape) as a whole, and can be integrally formed of, for example, a plastic material, and a window portion 3 is formed at a predetermined location. ing. The lamp 1 is mounted so as to be exposed to the outside corresponding to the window 3, and in this state, a light emitter (described later) of the lamp 1 blinks, lights up, etc., and functions as a direction indicator or the like. The traffic will show a left or right turn or a change of course.

  The lamp 1 of the present embodiment will be described. 4 is an exploded perspective view of the vehicular lamp 1 of the present embodiment, FIG. 5A is a plan view of the flexible substrate 4, and FIG. 5B is a side view of the same. As shown in FIG. 4, the lamp 1 includes a flexible substrate 4 having a strip shape, a base member 5 to which the flexible substrate 4 is attached and held, and a flexible substrate 4 attached to the base member 5. A reflector 6 for housing the flexible substrate 4 and a cover member 7 attached to the reflector 6 are provided.

  First, the flexible substrate 4 will be described. As shown in FIGS. 4 and 5, the flexible substrate 4 includes a thin belt-like substrate body 8 and four light emitters (LEDs 9, 10, 11, and 4) fixed to one surface (surface) of the substrate body 8. 12), the first to third back plates 13, 14, and 15 fixed to the other surface (back surface) of the substrate body 8 at the portions of the LEDs 9 to 12, and the LEDs 9 to 12 are supplied with power. Two lead wires 16 and a connector 17 are provided. In the flexible substrate 4 of this embodiment, the two LEDs 9 and 10 and the first back plate 13 are fixed to the front end portion of the substrate body 8, and the one LED 11 and the second LED 11 are attached to the central portion of the substrate body 8 in the longitudinal direction. The back plate 14 is fixed, and one LED 12 and the third back plate 15 are fixed to the rear end.

  The substrate body 8 is a copper-clad plate with excellent flexibility using polyimide, polyester or the like as a base film, which is patterned and coated with an insulating film or a liquid resist. A glass cloth base epoxy resin, a glass cloth base BT resin, or the like can be selected. Each of the LEDs 9 to 12 is a surface-mounted LED (SMD LED), and is mounted by means such as soldering in a form of being connected to a wiring pattern printed on the flexible substrate 4. Two LEDs 9 and 10 are fixed in parallel to the front end of the substrate body 8 in order to satisfy the legal light quantity.

  Each of the back plates 13 to 15 is attached to the substrate body 8 by an attaching means such as a double-sided tape. Each of the back plates 13 to 15 is only required to be harder than at least the flexible substrate body 8, and is made of a metal material such as copper, silver, gold, aluminum, nickel, platinum, palladium, or an inorganic material (non-metallic material) such as ceramic. Etc. There is no particular limitation. However, it is desirable to use a glass epoxy substrate (having good workability) to which a metal with high heat dissipation such as copper is attached, or aluminum (or aluminum alloy) that is inexpensive and has good heat dissipation. In this embodiment, since a glass epoxy substrate with copper attached on one side is used, temperature rise due to heat generation of each LED 9-12 can be suppressed, luminance deterioration is reduced, and each LED 9-12 is extended in life. Can be achieved.

  The front end portion of the first back plate 13 protrudes from the front end portion of the substrate body 8, and the width W1 thereof is slightly longer than the width W of the substrate body 8, so that the width direction (of the substrate body 8 of the substrate body 8) is increased. The first attachment portion 13a is attached to the base member 5 and extends in a direction perpendicular to the longitudinal direction. A cutout portion 18 is provided at the center portion in the width direction of the first attachment portion 13a to prevent displacement in the width direction when the first attachment portion 13a is attached to the base member 5. The width of the notch 18 is wider on the entrance side than on the back side. The second and third back plates 14 and 15 are substantially T-shaped, the widths W2 and W3 of the front end portions thereof are longer than the width W of the substrate body 8, and project from the substrate body 8 in the width direction. A second mounting portion 14a and a third mounting portion 15a are formed respectively.

  The flexible substrate 4 is formed symmetrically with respect to a center line (not shown) in the longitudinal direction. For this reason, it can be used as a common part for the left and right door mirror devices 100 in the vehicle C (see FIG. 1). Thereby, the number of parts of the whole door mirror device 100 in one vehicle C decreases, and the manufacturing cost can be suppressed.

  Next, the base member 5 will be described. 6 is a perspective view of the front portion of the flexible substrate 4 and the base member 5, FIG. 7A is a side view of the first attached portion 21 of the base member 5, and FIG. 6B is a state where the flexible substrate 4 is attached. It is a perspective view of the front part of base member 5 of. As shown in FIGS. 4 and 6, the base member 5 is formed of a thermoplastic resin such as ABS resin or ASA resin, and follows the shape of the housing 2 (see FIG. 2) constituting the vehicle door mirror device 100. It has a curved shape. The base member 5 is formed over substantially the entire area thereof, and is formed so as to protrude from a storage recess 19 for storing the flexible substrate 4 and a bottom surface portion 20 of the storage recess 19. The first to third attached portions 21, 22, and 23 into which the attachment portions 13a to 15a of the third back plates 13 to 15 are inserted are provided.

  The first attached portion 21 provided at the front end portion of the base member 5 includes a front projection 24 (first projection) and a rear projection 25 (second projection) disposed to face the front projection 24. And. The front protrusion 24 has a pair of L-shaped plate portions 26 erected at a predetermined interval in the width direction of the base member 5, and trapezoidal displacement prevention erected substantially at an intermediate position therebetween. The board part 27 and the connection board part 28 which connects those front side parts are provided. The thickness of the slip prevention plate portion 27 is slightly smaller than the inner width of the cutout portion 18 of the attachment portion 13a of the first back plate 13. Further, the rear protrusion 25 includes a pair of triangular plates 29 disposed between the displacement prevention plate 27 and the L-shaped plate 26 so as to sandwich the displacement prevention plate 27 of the front protrusion 24, and And a connecting plate portion 30 for connecting the rear side portions. A long guide rail portion 31 having a semicircular cross section is fixed to the upper surfaces of the pair of triangular plate portions 29. Thus, a gap 32 is formed between the front protrusion 24 and the rear protrusion 25 in which the attachment portion 13a of the first back plate 13 of the flexible substrate 4 is inserted (inserted).

  As shown in FIG. 7A, the inner width L of the gap 32 is slightly larger than the thickness t of the attachment portion 13 a of the first back plate 13. The first back plate 13 of the flexible substrate 4 is guided by the guide rail portion 31 fixed to the pair of triangular plate portions 29 and inserted into the gap 32. As shown in FIG. 7B, the attachment portion 13a of the first back plate 13 enters the notch portion 26a of the pair of L-shaped plate portions 26 and is restricted from moving in the front-rear direction. Further, when the first back plate 13 is inserted to the deepest part of the gap 32, the notch portion 18 of the first back plate 13 is fitted to the shift prevention plate portion 27. Since the notch width on the inlet side of the notch portion 18 of the first back plate 13 is wider than the depth side, the operation of fitting the notch portion 18 to the slip prevention portion 25 is easy. Thereby, the 1st backplate 13 inserted in the clearance gap 32 is restrained in the width direction, and becomes difficult to shift | deviate in the width direction. As a result, movement of the flexible substrate 4 in the front-rear direction and the left-right direction (width direction) in the first back plate 13 is restricted, and the first back plate 13 is held by the first attached portion 22. In order to securely hold the first back plate 13 inserted into the gap 32 of the first attached portion 22, the notch lengths L and L ′ of the notch portions 26a in the pair of L-shaped plate portions 26 are set to the back side. Gradually (continuously), and the notch length L ′ at the deepest portion is made shorter than the thickness of the mounting portion 13a of the first back plate 13 (that is, L> t> L ′). Is desirable. Thereby, when the attachment part 13a of the first back plate 13 is inserted to the deepest part of the gap 32, the first back plate 13 is held by the notch portions 26a of the pair of L-shaped plate parts 26 by a frictional force, It will be in the retaining state.

  Since the 2nd and 3rd to-be-attached parts 22 and 23 are substantially the same shape, only the 2nd to-be-attached part 22 is demonstrated in this specification. As shown in FIGS. 4 and 6, the second attached portion 22 is substantially L-shaped in plan view, and is symmetrical with respect to a center line (not shown) in the longitudinal direction of the base member 5. In this manner, the pair of support plate portions 33 (first protrusions) fixed to the bottom surface portion 20 and the front wall portion 33a of the pair of support plate portions 33 are arranged to face each other with a predetermined interval (gap 34). And a support wall 35 (second protrusion). Like the first attached portion 21, a pair of guide rail portions 36 having a semicircular cross section and an elongated shape are provided on the front wall portion of the support wall portion 35 with a predetermined interval in the width direction of the base member 5. Is fixed.

  Also in the second mounted portion 22, the second back plate 14 of the flexible substrate 4 is guided by the pair of guide rail portions 36 and inserted into the gap 34, similarly to the first mounted portion 21. At this time, the attachment portion 14 a of the second back plate 14 is restrained in the front-rear direction and the left-right direction (width direction) by the pair of support plate portions 33. As a result, the movement of the flexible substrate 4 in the front-rear direction and the left-right direction on the second back plate 14 is restricted, and the second back plate 14 is held by the second attached portion 23.

  As shown in FIG. 7B, when the first and second back plates 13 and 14 of the flexible substrate 4 are attached to the first and second attached portions 21 and 22, the substrate body 8 is Due to its own weight, the upper surface of the connecting plate portion 30 of the first attached portion 21, the upper surface of the support wall portion 35 of the second attached portion 22, and the bottom portion 20 of the storage recess 19 of the base member 5 are arranged.

  As shown in FIG. 4, a through hole 37 for passing the lead wire 16 of the flexible substrate 4 and an engaging claw 38 (described later) of the reflector 6 are engaged with the rear end portion of the housing recess 19 of the base member 5. A locking hole 39 for stopping is provided. When the corresponding back plates 13 to 15 of the flexible substrate 4 are inserted and attached to the attached portions 21 to 23 of the base member 5, the lead wires 22 pass through the through holes 37 and are external to the base member 5. To be issued. The connector 17 is attached to the through hole 37. In addition, brackets 41 and 42 provided with through holes for screws (not shown) for fixing the base member 5 to the housing 2 of the door mirror device 100 are provided on the side wall portion of the base member 5. .

  Next, the reflector 6 will be described. FIG. 8 is a bottom view of the reflector 6. The reflector 6 is made of metal, resin, ceramic, or the like. In consideration of the design of the door mirror device 100, for example, a resin material subjected to vapor deposition, gloss coating, plating, or the like, or a metal material such as aluminum having a mirror finish can be used. As shown in FIG. 4, the reflector 6 is curved corresponding to the curved state of the base member 5. Locking claws 38 that can be elastically deformed are provided on both side surfaces of the reflector 6. In the reflector 6, openings 43, 44, 45 for exposing them to the outside are provided at positions corresponding to the LEDs 9 to 12 of the flexible substrate 4. Further, as shown in FIG. 8, on the back surface of the reflector 6, protrusions 46, 47, 48 for pressing the flexible substrate 4 attached to the base member 5 toward the base member 5 are provided. Each is provided in two rows.

  The reflector 6 is housed and attached in the housing recess 19 of the base member 5 to which the flexible substrate 4 is attached. At this time, each LED 9-12 of the flexible substrate 4 is arrange | positioned in the part of the opening parts 43-45 of the corresponding reflector 6. FIG. Thereby, light emission of each LED9-12 is irradiated outside through the corresponding opening parts 43-45. Further, the locking claw 38 of the reflector 6 that is elastically deformed by contacting the wall surface of the housing recess 19 of the base member 5 enters the locking hole 39 of the corresponding base member 5 and is elastically restored. As a result, the reflector 6 can be prevented from being pulled out. Further, the protrusions 46 to 48 of the reflector 6 press the flexible substrate 4 attached to the base member 5. Thereby, the displacement of the flexible substrate 4 is prevented.

  Next, the cover member 7 will be described. As shown in FIG. 4, a cover member 7 is attached to the reflector 6. The cover member 7 is formed of, for example, a transparent or translucent thermoplastic resin such as polymethyl methacrylate (PMMA), polycarbonate (PC), polypropylene (PP), or ABS resin, and the vehicle door mirror device 100 (housing 2). A curved shape that follows the shape of A lens portion 49 is provided on the surface side of the cover member 7. Light emitted from each of the LEDs 9 to 12 is irradiated to the outside through the lens portion 49 of the cover member 7. The lens portion 49 covers the openings 43 to 45 of the reflector 6 to protect the exposed LEDs 9 to 12 and improve the design of the door mirror device 100.

  A method for assembling the lamp 1 of this embodiment will be described. In the lamp 1 of the present embodiment, the flexible substrate 4 is first attached to the base member 5. As shown in FIG. 4 and FIG. 7A, the first back plate 13 of the flexible substrate 4 is attached to the first attached portion 21 of the base member 5. That is, the bottom surface of the first back plate 13 attached to the substrate body 8 of the flexible substrate 4 is directed to the guide rail portion 31 fixed to the upper surfaces of the pair of triangular plate portions 29 of the first attached portion 21, As it is, it is slid downward (bottom surface portion 20 of the housing recess 19 of the base member 5). Since the guide rail portion 31 is disposed obliquely with respect to the bottom surface portion 20 of the storage recess 19 of the base member 5, the operation of sliding the first back plate 13 is easy. In addition, since the inner width of the storage recess 19 of the base member 5 is much wider than the width of the operator's finger, it is easy for the operator to apply the bottom surface of the first back plate 13 to the guide rail portion 31. is there. When the first back plate 13 is slid, the cutout portion 18 is fitted into the shift prevention portion 27 of the front projection 24. Since the notch width on the inlet side of the notch portion 18 is wider than that on the back side, the operation of fitting the slip prevention portion 27 is easy.

  As shown in FIG. 7B, the mounting portion 13 a of the first back plate 13 inserted to the deepest portion of the gap 32 of the first mounted portion 21 is guided to the pair of L-shaped plate portions 26. While being sandwiched by the rail portion 31 and being displaced in the front-rear direction, it is restricted from moving in the width direction by the shift prevention plate portion 27. And it hold | maintains by the frictional force which acts between the notch parts 26a of a pair of L-shaped board part 26. FIG. At this time, since it is only the portion of the attachment portion 13a of the first back plate 13 that is restricted by the pair of L-shaped plate portions 26 in the front-rear direction, there is no possibility that the substrate body 8 is damaged.

  In almost the same manner, the second back plate 14 is attached to the second attached portion 22. In the case of the second back plate 14, the pair of support plate portions 33 restricts the second back plate 14 from shifting in the front-rear direction and the width direction. Further, since the space between the pair of support plate portions 33 is open, there is no possibility that the substrate body 8 is damaged. The third back plate 15 is attached to the third attached portion 23 in exactly the same manner.

  As shown in FIG. 4, the reflector 6 is attached to the base member 5 to which the flexible substrate 4 is attached. The reflector 6 is held in a retaining state by the locking claw 38 entering the locking hole 39 of the storage recess 19 of the base member 5 and being locked. At this time, the protrusions 46 to 48 of the reflector 6 press the flexible substrate 4. For this reason, the displacement of the flexible substrate 4 is further effectively prevented.

  And the cover member 7 is attached to the reflector 6, and each opening part 43-45 of the reflector 6 is covered. The lamp 1 assembled in this way is attached to the housing 2 of the door mirror device 100 (see FIG. 3).

  A modification of the lamp 1 according to the above embodiment will be described. As shown in FIG. 9A, the concave portions 51 are provided at two locations on the mounting portion 13 a of the first back plate 13 of the flexible substrate 4, and the pair of L-shaped first mounting portions 21 of the base member 5. A convex portion 52 (locking portion) is provided in the notch portion 26 a of the plate-like plate portion 26. When the mounting portion 13a of the first back plate 13 is inserted into the gap 32 of the first mounted portion 21, the convex portion 52 is elastically deformed, and when the mounting portion 13a reaches the deepest portion of the gap, the convex portion 52 is It fits into the recess 51 (see FIG. 7B). Thereby, the shift | offset | difference of the flexible substrate 4 becomes still smaller. Similar concave portions 51 and convex portions 52 may be provided on the mounting portions 14 a and 15 a of the first and third back plates 14 and 15 and the corresponding second and third mounted portions 22 and 23.

  Next, another modified example will be described. As shown in FIG. 10A, the first attached portion 21 may be provided perpendicular to the bottom surface portion 20 of the base member 5. Further, in order to prevent the first back plate 13 sandwiched between the front projection 24 and the rear projection 25 of the first attached portion 21, an upright wall 53 adjacent to the rear projection 25 is provided. A claw body 54 that projects toward the front wall portion 53 may be provided at the upper end portion. As shown in FIG. 10B, when the first back plate 13 is inserted into the gap 32 of the attached portion 21, the claw body 54 of the standing wall portion 53 is pressed and the standing wall portion 53 is elastically deformed. Entry into the gap 32. When the first back plate 13 reaches the deepest portion of the gap 32, the claw body 54 is elastically restored and is locked to the shoulder portion 13 b of the first back plate 13. Thereby, the 1st backplate 13 is hold | maintained at the to-be-attached part 21 in the retaining state. In this way, the attached portions 21 and 22 may be provided perpendicular to the bottom surface portion 20 of the base member 5.

  As described above, in the conventional lamp, the flexible substrate is first attached to the reflector, and then the reflector is attached to the base member. On the other hand, in the lamp 1 of the present embodiment, the flexible substrate 4 is first attached to the base member 5, and then the reflector 6 and the cover member 7 are attached. For this reason, the operator only needs to attach the flexible substrate 4 to the base member 5 in the open state, and does not need to put the finger in the narrow reflector 6 and attach the flexible substrate 4. Thereby, even if the width | variety of the reflector 6 becomes narrow from a design viewpoint, the lamp 1 can be assembled in a state where the flexible substrate 4 is accurately positioned on the base member 5 without being affected by the width. Also, the number of parts does not change. And since the back plates 13-15 become large by the part which provided the attachment parts 13a-15a in each backplate 13-15, the heat dissipation effect is also improved.
