Description

[Technical Field]

[0001] The present invention relates to a vehicle lighting device. [Background technology]

[0002] Vehicle lighting devices have been known as turn signal devices that are provided on motorcycles from the side of the vehicle body toward the outside in the vehicle width direction. A vehicle lighting device includes, for example, a substrate having a light emitter mounted on one surface and a housing that houses the substrate. An opening is formed in the front of the housing. A lens is provided to close the opening. The substrate is positioned so that the light emitter faces the opening.

[0003] Furthermore, some vehicle lighting devices of this type have a direct connector provided within the housing. The direct connector is for electrically connecting the circuit board and the external connector. The direct connector is disposed closer to the vehicle body of the housing. The direct connector has a terminal insertion hole formed along the vehicle width direction. Terminals extend from the circuit board toward the vehicle body along the surface direction of the circuit board. The terminals are inserted into the terminal insertion hole of the direct connector. The terminals extending from the circuit board are then electrically connected to the external connector via the direct connector. This eliminates the need to route the external connector deep into the housing to connect the external connector to the circuit board. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6673795 Summary of the Invention [Problem to be solved by the invention]

[0005] When assembling the vehicle lighting device described above, the board is inserted into the housing from the opening toward the rear. At the same time, the terminals of the board must be inserted into the terminal insertion holes of the direct connector, which are aligned along the vehicle width direction. This makes it difficult to assemble the board into the housing, which reduces the ease of assembly of the vehicle lighting device.

[0006] For example, if the diameter of the terminal insertion hole of the direct connector is made larger in order to improve the ease of assembling the board to the housing, dust and other particles can easily enter the housing through the terminal insertion hole. Furthermore, the larger the diameter of the terminal insertion hole, the more difficult it is to seal the terminal insertion hole. This poses a problem of poor sealing ability between the vehicle lighting device and the outside.

[0007] SUMMARY OF THE INVENTION The present invention provides a vehicle lighting device that can improve assembly efficiency and sealing performance from the outside. [Means for solving the problem]

[0008] In order to solve the above problems, the vehicle lighting device of the present invention comprises a substrate having an illuminant mounted on one surface and having terminals to which an external connector is connected, a housing for accommodating the substrate, a cover having terminal insertion holes into which the terminals are inserted and receiving the external connector from one end face opposite to the insertion direction of the terminals and connecting the terminals to the external connector, and a sealing member, wherein the terminals extend in a direction intersecting the normal direction of the one face, the housing has an opening for exposing the one face, and a cover insertion hole formed therein through which the cover can be inserted toward the terminals, and a partition portion for separating the side on which the substrate is located from the side on which the external connector is located, and the sealing member ensures sealing between the one end face of the cover and the external connector, and between the cover and the cover insertion hole. [Effects of the Invention]

[0009] According to the present invention, the assembly efficiency of the vehicle lamp device can be improved, and the sealing performance from the outside can also be improved. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] Next, an embodiment of the present invention will be described with reference to the drawings.

[0012] <Vehicle lighting device> Fig. 1 is a horizontal cross-sectional view of a vehicle lighting device 1 provided on the left side of a vehicle body 101. Fig. 2 is a perspective view of the vehicle lighting device 1 of Fig. 1 as viewed from the right. The vehicle lighting device 1 is, for example, a so-called blinker device attached to both front sides of a body 101 of a motorcycle 100. The vehicle lighting devices 1 provided on both sides of the body 101 are symmetrical with respect to the body 101 and have the same configuration. Therefore, in the following explanation, only the vehicle lighting device 1 provided on the left side of the body 101 will be explained.

[0013] In the following description, the width direction of the body 101 may be referred to as the left-right direction. The forward direction in the traveling direction of the motorcycle 100 will be simply referred to as the front, and the backward direction in the traveling direction will be simply referred to as the rear. The up-down direction in the direction of gravity will be simply referred to as the up-down direction. In the following drawings, the forward direction is indicated by an arrow FR, the left side (outside in the vehicle width direction) is indicated by an arrow LH, and the upward direction is indicated by an arrow UP.

[0014] As shown in FIGS. 1 and 2, a vehicle lighting device 1 includes a housing 2, and a substrate 3, a cover 4, and a seal member 5 housed in the housing 2.

[0015] <Housing> The housing 2 is made of, for example, resin. The housing 2 is integrally formed with a box-shaped housing main body 6 having an opening 6a formed in the front and a fixing part 7 attached to the right end of the housing main body 6 for fixing the vehicle lamp device 1 to the vehicle body 101.

[0016] The housing main body 6 is formed so as to be long in the left-right direction. The periphery of the opening 6a is formed so as to follow the left-right direction, and is formed in an oval shape that is long in the left-right direction when viewed from the front. A mounting groove 6b for mounting a lens (not shown) is formed in the periphery of the opening 6a. The lens (not shown) is provided so as to close the opening 6a. The lens (not shown) is fixed so that its periphery fits into the mounting groove 6b.

[0017] The housing body 6 is also tapered to the left. Therefore, the rear bottom portion 6c of the housing body 6 extends obliquely to be positioned forward as it moves leftward. A plurality of support protrusions 8, 9, 10 (first support protrusion 8, second support protrusion 9, third support protrusion 10) are formed on the bottom portion 6c and protrude toward the opening 6a. The plurality of support protrusions 8, 9, 10 support the board 3.

[0018] Of the multiple support protrusions 8, 9, 10, the first support protrusion 8, which is arranged closer to the fixed portion 7, is formed in a plate shape. The substrate 3 is placed on the first support protrusion 8. The first support protrusion 8 has a slit 8a formed therein into which a pin portion 16 of a terminal 14, which will be described later, is inserted. The second support protrusion 9 and the third support protrusion 10 are arranged to the left of the first support protrusion 8. The second support protrusion 9 and the third support protrusion 10 are arranged in this order toward the left. The second support protrusion 9 and the third support protrusion 10 are formed in a cylindrical shape.

[0019] The substrate 3 is placed on these support protrusions 9, 10. Female threads 9a, 10a are formed at the front ends of the second support protrusion 9 and the third support protrusion 10. The substrate 3 is fastened and fixed onto each of the support protrusions 8 to 10 by tightening bolts (not shown) into the female threads 9a, 10a. The protruding height of each of the support protrusions 8 to 10 gradually decreases so that the substrate 3 is placed along the left-right direction. In other words, the protruding height of the second support protrusion 9 is lower than the protruding height of the first support protrusion 8. The protruding height of the third support protrusion 10 is lower than the protruding height of the second support protrusion 9.

[0020] A partition wall portion 11 is formed on the housing main body 6 to the right of the first support protrusion 8, separating the housing main body 6 and the fixed portion 7. A cylindrical portion 12 is integrally molded in the center of the partition wall portion 11 in the front-to-rear direction. The cylindrical portion 12 extends in the left-to-right direction so that its axial direction is along the left-to-right direction. The cylindrical portion 12 is formed in a slightly square cylindrical shape so that it is slightly longer in the front-to-rear direction when viewed in the left-to-right direction. The cylindrical portion 12 is provided to penetrate the partition wall portion 11. A hole formed by the cylindrical portion 12 functions as a cover insertion hole 12a into which the cover 4 is inserted. This will be described in detail later.

[0021] The partition wall portions 11 are arranged so as to be offset from each other at the front and rear with the cylindrical portion 12 sandwiched therebetween. That is, the rear wall portion 11b of the partition wall portion 11, which is arranged on the rear side of the cylindrical portion 12, is arranged to be offset to the left from the position of the front wall portion 11a, which is arranged on the front side of the cylindrical portion 12. A left side surface 11c of the rear wall portion 11b and a left end portion 12b of the cylindrical portion 12 are positioned on the same plane. A predetermined gap G is formed between the left side surface 11c of the rear wall portion 11b (left end portion 12b of the cylindrical portion 12) and the first support protrusion 8.

[0022] The fixed portion 7 is formed in a cylindrical shape so as to be approximately concentric with the cylindrical portion 12. The fixed portion 7 surrounds the periphery of the cylindrical portion 12. The right end of the fixed portion 7 is fixed to the vehicle body 101. An external connector 102 is exposed inside the fixed portion 7 from the vehicle body 101 side (right end) of the fixed portion 7. The external connector 102 is connected to a battery (not shown) mounted on the vehicle body 101, and supplies power to the vehicle lighting device 1.

[0023] <Substrate> The substrate 3 arranged on each of the support protrusions 8 to 10 is located slightly behind the opening 6a of the housing main body 6. The substrate 3 is formed long in the left-right direction so as to correspond to the shape of the opening 6a. A plurality of light emitters 13 are mounted on the front-facing surface 3a (an example of a surface in the claims) of the substrate 3. Light emitted from these light emitters 13 is irradiated forward via the opening 6a and a lens (not shown).

[0024] A plurality of terminals 14 (for example, two in this embodiment) are mounted on the right end of the rear surface 3b of the substrate 3. The terminals 14 have a connection portion 15 connected to the rear surface 3b of the substrate 3 and a pin portion 16 protruding from the connection portion 15 to the right.

[0025] The pin portion 16 has a pin support portion 16a that forms the base end on the connection portion 15 side, and a pin main body 16b that extends rightward from the pin support portion 16a along the left-right direction. The surface 3a of the substrate 3 and the terminal 14 (pin portion 16) extend in the same direction. In other words, the terminal 14 (pin portion 16) extends in a direction that intersects with the normal direction of the surface 3a of the substrate 3. The pin support portion 16a is inserted into the slit 8a of the first support protrusion 8. The pin main body 16b then protrudes rightward through the first support protrusion 8. The pin main body 16b faces the inside of the cylindrical portion 12.

[0026] <Cover> Fig. 3 is an exploded perspective view of the cover 4 and the seal member 5 as seen from the left, and Fig. 4 is an exploded perspective view of the cover 4 and the seal member 5 as seen from the right. As shown in Figures 2 to 4, the cover 4 is made of, for example, resin. The cover 4 is a block body formed so that it can be inserted into the cylindrical portion 12 from the right and fitted thereto. The outer shape of the cover 4 is formed in a slightly rectangular shape that is slightly longer in the front-to-rear direction when viewed from the left-to-right direction so as to correspond to the shape of the hole (cover insertion hole 12a) in the cylindrical portion 12. Such a cover 4 is inserted into the cylindrical portion 12. In other words, the hole in the cylindrical portion 12 functions as the cover insertion hole 12a into which the cover 4 is inserted.

[0027] A connector insertion recess 17 is formed in most of the center of a right end surface (an example of an end surface in the claims) 4a of the cover 4 when viewed from the left and right. An external connector 102 is fitted into the connector insertion recess 17. A plurality of (for example, two in this embodiment) terminal insertion holes 18 are formed in the left end surface 4b of the cover 4, penetrating in the left-right direction. The diameter of the terminal insertion holes 18 is slightly larger than the shaft diameter of the pin body 16b. The terminal insertion holes 18 communicate with the left side of the cover 4 and the connector insertion recess 17.

[0028] The terminal insertion hole 18 is disposed at a position corresponding to the pin body 16b when the cover 4 is inserted into the cylindrical portion 12. When the cover 4 is inserted into the cylindrical portion 12, the pin body 16b is inserted into the terminal insertion hole 18. The tip of the pin body 16b protrudes into the connector insertion recess 17 of the cover 4. A countersunk portion 18a is formed on the left end surface 4b of the cover 4 at a location corresponding to the terminal insertion hole 18. The countersunk portion 18a functions as a guide when inserting the pin body 16b into the terminal insertion hole 18 of the cover 4.

[0029] A recess 19 is formed on the lower surface 4c of the outer circumferential surface of the cover 4, extending from the left end surface 4b to a point slightly short of the right end surface 4a. A tongue portion 20 is formed on the right side of this recess 19 and extending leftward. The tongue portion 20 is formed so as to be elastically deformable in the vertical direction. A claw portion 21 is integrally formed on the lower surface 20a at the tip (left end) of the tongue portion 20.

[0030] When the cover 4 is inserted into the cylindrical portion 12, the tongue portion 20 and the claw portion 21 are pushed up and elastically deformed. When the claw portion 21 passes through the cylindrical portion 12, a restoring force acts on the tongue portion 20, and the claw portion 21 engages with the left end portion 12b of the cylindrical portion 12. In other words, the tongue portion 20 and the claw portion 21 serve to fix the cover 4 to the cylindrical portion 12 by snap-fitting.

[0031] Two round rod-shaped engagement protrusions 22 that protrude to the right are integrally molded on the right end surface 4a of the cover 4, on both the front and rear sides of the connector insertion recess 17. A return portion 23 is integrally molded at the tip of the engagement protrusion 22. The return portion 23 is formed in a disk shape with a diameter larger than the shaft diameter of the engagement protrusion 22. The return portion 23 is also formed in a smooth tapered shape that tapers toward the right. The engagement protrusions 22 and the return portion 23 are intended to integrate the cover 4 and the seal member 5.

[0032] <Sealing material> The sealing member 5 is made of a compressible elastic material. For example, the sealing member 5 is made of rubber or the like. However, the sealing member 5 is not limited to this, and any compressible elastic material having sealing properties may be used. A porous material may also be used as the sealing member 5.

[0033] The seal member 5 is formed in a slightly square annular shape that is slightly longer in the front-rear direction when viewed from the left-right direction so as to correspond to the shape of the right end surface 4a of the cover 4. The seal member 5 covers the right end surface 4a of the cover 4. The outer shape of the seal member 5 is formed to be slightly larger than the shape of the cover insertion hole 12a of the cylindrical portion 12.

[0034] An engagement hole 24 is formed in the seal member 5 at a position corresponding to the engagement protrusion 22. The cover 4 and the seal member 5 are integrated by press-fitting the engagement protrusion 22 into this engagement hole 24. When the cover 4 and the seal member 5 are assembled together, a return portion 23 at the tip of the engagement protrusion 22 protrudes from the right end surface 5a of the seal member 5. The return portion 23 prevents the seal member 5 from coming off the engagement protrusion 22.

[0035] <Method for assembling a vehicle lighting device> Next, a method for assembling the vehicle lighting device 1 will be described with reference to FIGS. Fig. 5 is an explanatory diagram of assembling the substrate 3 to the housing 2. Fig. 5 corresponds to Fig. 1. The vehicle lighting device 1 can be assembled before assembling the housing 2 to the vehicle body 101. However, for convenience, the following description will be given assuming that the housing 2 is already assembled to the vehicle body 101.

[0036] As shown in Fig. 5, first, the board 3 is assembled to the housing 2. At this time, the cover 4 and the seal member 5 are not attached to the terminals 14 of the board 3. In this state, with the surface 3a of the board 3 facing forward, the board 3 is inserted into the housing main body 6 through the opening 6a of the housing main body 6. At this time, the board 3 is inserted into the housing main body 6 while inserting the pin bodies 16b of the terminals 14 obliquely into the cylindrical portion 12 (see the arrow in Fig. 5).

[0037] At this time, the cover 4 and the seal member 5 are not attached to the cover insertion hole 12a of the cylindrical portion 12. Therefore, the cover insertion hole 12a of the cylindrical portion 12 is in a wide open state. As a result, the pin body 16b of the terminal 14 can be easily inserted obliquely with respect to the axial direction (left-right direction) of the cylindrical portion 12. The posture of the substrate 3 is changed while inserting the pin body 16b of the terminal 14 into the cylindrical portion 12, and the substrate 3 is placed on each of the support protrusions 8 to 10. Then, the substrate 3 is fastened and fixed onto each of the support protrusions 8 to 10 with bolts (not shown).

[0038] Next, the cover 4 and the seal member 5 are inserted into the cover insertion hole 12a of the cylindrical portion 12 from the right side of the cylindrical portion 12. At this time, the engaging protrusion 22 of the cover 4 is press-fitted into the engaging hole 24 of the seal member 5 in advance to integrate the cover 4 and the seal member 5. Then, of the integrated cover 4 and seal member 5, the cover 4 side is inserted toward the cylindrical portion 12. Then, the pin body 16b is inserted into the terminal insertion hole 18 of the cover 4. A counterbore portion 18a is formed on the left end surface 4b of the cover 4, and this counterbore portion 18a serves as a guide to adjust the position of the pin body 16b and the terminal insertion hole 18. Therefore, the pin body 16b is easily inserted into the terminal insertion hole 18 of the cover 4.

[0039] Thereafter, the cover 4 is inserted into the cover insertion hole 12a until the cover 4 is snap-fitted to the cylindrical portion 12. At this time, the seal member 5 is inserted into the cover insertion hole 12a together with the cover 4. Because the outer shape of the seal member 5 is formed to be slightly larger than the shape of the cover insertion hole 12a of the cylindrical portion 12, the seal member 5 is inserted into the cover insertion hole 12a in a state where it is slightly compressed and deformed radially inward. As a result, the inner circumferential surface of the cover insertion hole 12a and the outer circumferential surface of the seal member 5 are tightly attached to each other.

[0040] When the cover 4 is snap-fitted to the cylindrical portion 12, assembly of the vehicle lamp device 1 is completed. Here, the cover 4 only has a terminal insertion hole 18 that is slightly larger than the shaft diameter of the pin body 16b, so that sealing is ensured between the housing body 6 side and the fixed portion 7 side of the housing 2 via the cover 4. In addition, sealing member 5 ensures sealing between the cover insertion hole 12a and the cover 4.

[0041] After the assembly of the vehicle lighting device 1 is completed, the external connector 102 is inserted into the connector insertion recess 17 of the cover 4 via the seal member 5. The pin body 16b protrudes into the connector insertion recess 17 of the cover 4, and the pin body 16b and the external connector 102 are connected. This allows power to be supplied to the vehicle lighting device 1.

[0042] When the external connector 102 is inserted into the connector insertion recess 17 of the cover 4, the seal member 5 is interposed between the cover 4 and the external connector 102. The periphery between the cover 4 and the external connector 102 is covered by the seal member 5. In this state, the seal member 5 is slightly compressed by the right end face 4a of the cover 4 and the external connector 102. Therefore, the seal member 5 ensures sufficient sealing between the cover 4 and the external connector 102.

[0043] The external connector 102 is formed to avoid interference with the return portion 23 when it is attached to the connector insertion recess 17 of the cover 4. This prevents the return portion 23 formed on the engagement projection 22 of the cover 4 from interfering with close contact between the external connector 102 and the seal member 5.

[0044] As described above, the vehicle lighting device 1 includes the cover 4 and the seal member 5 in addition to the housing 2. The housing 2 includes a partition wall portion 11 that separates the housing main body 6, in which the circuit board is disposed, from the fixed portion 7, in which the external connector 102 is disposed, and a cover insertion hole 12a formed in the partition wall portion 11. The cover 4 includes a terminal insertion hole 18 into which the terminal 14 (pin body 16b) is inserted. After the terminal 14 (pin body 16b) is inserted into the cover insertion hole 12a, the cover 4 is inserted into the cover insertion hole 12a from the vehicle body 101 side. The terminal 14 and the external connector 102 are connected via the cover 4. This allows the cover insertion hole 12a to be formed sufficiently large, making it easy to insert the terminal 14 (pin body 16b) into the cover insertion hole 12a. This improves the ease of assembly of the vehicle lighting device 1.

[0045] The diameter of the terminal insertion hole 18 in the cover 4 can be large enough to insert the pin body 16b of the terminal 14. In other words, the diameter of the terminal insertion hole 18 can be made slightly larger than the shaft diameter of the pin body 16b. This makes it difficult for dust to enter the housing body 6 from the terminal insertion hole 18 in the cover 4. Furthermore, the seal member 5 ensures a seal between the cover insertion hole 12a and the cover 4. Furthermore, the seal member 5 ensures a seal between the cover insertion hole 12a and the cover 4.

[0046] By providing the engaging projections 22 on the cover 4 and forming the engaging holes 24 in the seal member 5, the cover 4 and the seal member 5 can be easily integrated together. This makes it possible to simultaneously assemble the cover 4 and the seal member 5 to the housing 2. This further improves the ease of assembly of the vehicle lamp device 1. A return portion 23 is integrally formed at the tip of the engaging projection 22. Therefore, the return portion 23 can prevent the seal member 5 from coming off the engaging projection 22, and the cover 4 and the seal member 5 can be reliably integrated.

[0047] When forming the cover insertion hole 12a in the partition wall 11, the cylindrical portion 12 is integrally molded with the partition wall 11. The cover 4, the seal member 5, and the external connector 102 are inserted into this cylindrical portion 12. This makes it easy to fix the cover 4, the seal member 5, and the external connector 102 to the housing 2. Furthermore, the ease of assembling the cover 4 and the seal member 5 to the housing 2 can be improved.

[0048] Since this improves the assembly ease of vehicle lighting devices 1, it will be possible to contribute to Goal 9 of the United Nations-led Sustainable Development Goals (SDGs), which is to "Build resilient infrastructure, promote inclusive and sustainable industrialization, and foster innovation." In addition, the sealing performance between the inside and outside of the housing main body 6 in the vehicle lighting device 1 can be improved, which stabilizes the quality of the vehicle lighting device 1 and makes it possible to contribute to Goal 7 of the United Nations-led Sustainable Development Goals (SDGs), which is to "Ensure access to affordable, reliable, sustainable, and modern energy for all."

[0049] The present invention is not limited to the above-described embodiment, and includes various modifications to the above-described embodiment without departing from the spirit of the present invention. For example, in the above embodiment, the vehicle lighting device 1 is described as being provided on a motorcycle 100. However, the present invention is not limited to this, and the vehicle lighting device 1 can be used on various vehicles such as four-wheeled motor vehicles.

[0050] In the above embodiment, the cover 4 and the seal member 5 are integrated together by forming the engaging protrusions 22 on the cover 4 and forming the engaging holes 24 in the seal member 5 to receive (press-fit) the engaging protrusions 22. However, this is not limiting, and the engaging protrusions 22 may be formed on the seal member 5 and the engaging holes 24 may be formed on the cover 4. Furthermore, it is sufficient that the cover 4 and the seal member 5 are integrated together; for example, the cover 4 and the seal member 5 may be molded in two colors. [Explanation of symbols]
