The present invention relates to the technical field of a vehicular lamp in which a light source board and a control board are attached to a lamp housing by thermal caulking.

In vehicle lighting equipment such as Howemount stop lamps, a light source board on which a light source is mounted and a control board that controls turning on and off the light source are attached to the lamp housing. There is a structure in which the light is transmitted through a cover (cover lens) and irradiated to the outside (for example, see Patent Document 1). In Patent Document 1, a light source board is provided as a light emitting element mounting section, and a control board is provided as a control circuit section.

Some of these vehicle lamps include a light source board and a control board that are attached to a mounting portion of a lamp housing by thermal caulking. In this case, an insertion hole is formed in the light source board and the control board, a crimping pin is provided in the mounting part, and the crimping jig applies heat and pressure to the crimping pin while the crimping pin is inserted into the insertion hole. The light source board and the control board are attached to the attachment part by deforming the tip of the caulking pin.

Japanese Patent Application Publication No. 2019-153494

By the way, in the installation process of attaching the light source board and control board to the mounting part of the lamp housing by heat caulking, the light source board and control board are usually attached to the mounting part using crimping jigs at multiple locations, so the installation process is difficult. If the number of locations increases, the number of caulking operations will increase accordingly, and the work in the attachment process will take time, which may reduce work efficiency.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to improve workability in the process of attaching a light source board and a control board to a lamp housing by thermal caulking.

First, the vehicular lamp according to the present invention includes a lamp housing having a mounting base, a light source board on which a light source is mounted, and a control board that controls turning on and off the light source, and the lamp housing has the mounting base. A first attachment part and a second attachment part are provided which protrude from the base in opposite directions and to which the light source board and the control board are respectively attached by thermal caulking, and the first attachment part and the second attachment part are provided. They are located on the same straight line.

As a result, the light source board and the control board are simultaneously pressed from opposite directions to the first mounting part and the second mounting part, which protrude from the mounting base in opposite directions and are located on the same straight line. It becomes possible to attach to the first attachment part and the second attachment part, respectively.

Second, the first mounting portion has a first base protrusion continuous to the mounting base and a first caulking pin protruding from a distal end surface of the first base protrusion, and The mounting part has a second base protrusion continuous to the mounting base and a second caulking pin protruding from the distal end surface of the second base protrusion, and the first mounting part A first reinforcing rib protruding from the outer circumferential surface of the base protrusion is provided, and a second reinforcing rib protruding from the outer circumferential surface of the second base protrusion is provided at the second attachment part. is desirable.

As a result, the strength of the first base protrusion and the second base protrusion is increased by the first reinforcing rib and the second reinforcing rib, respectively. The first attachment part and the second attachment part are not easily deformed when they are pressed against each other and thermally caulked.

Thirdly, the lamp housing is formed of a resin material, and a plurality of the first reinforcing ribs and the second reinforcing ribs are provided spaced apart from each other in the circumferential direction, and a position of the first reinforcing rib in the circumferential direction is provided. It is desirable that the position of the reinforcing rib and the position of the second reinforcing rib in the circumferential direction are different from each other.

This suppresses the occurrence of sink marks on the mounting base during molding of the lamp housing.

Fourthly, a first heat sink having a first insertion hole into which the first caulking pin is inserted and attached to the first mounting portion in contact with the light source board; It is desirable that a second heat dissipation plate is provided, which has a second insertion hole into which the heat dissipation plate is inserted, and is attached to the second attachment part in contact with the control board.

As a result, when the crimping jig is pressed against the first crimping pin to perform thermal crimping, the first heat sink is attached to the first mounting part in addition to the light source board at the same time, and the crimping jig is pressed against the second crimping pin. When the jig is pressed and thermal caulking is performed, the second heat sink is attached to the second attachment part in addition to the control board at the same time.

Fifth, it is desirable that the first heat sink and the second heat sink be located on opposite sides of the mounting base.

As a result, the heat emitted from the first heat sink and the second heat sink when the light source is driven by the on/off control of the control board is separated by the mounting base, and is unlikely to affect the driving states of the light source and the control board.

According to the present invention, a crimping jig is simultaneously pressed from opposite directions to the first mounting part and the second mounting part, which are protruded from the mounting base in opposite directions and positioned on the same straight line, and the light source board is attached to the light source board. Since the control board can be attached to the mounting base, the working time in the mounting process can be shortened, and the workability in the mounting process in which the light source board and the control board are attached to the lamp housing by thermal caulking can be improved.

A power supply connector 38 is connected to the front surface of the control board 35.

Below, a procedure for assembling the vehicle lamp 1 configured as described above will be explained.

First, the first caulking pins 15, 15, 15 of the first mounting portions 11, 11, 11 in the case body 5 are inserted into the first insertion holes 26a, 26a, 26a of the first heat sink 25, respectively. The second caulking pins 18, 18, 18 of the second mounting portions 12, 12, 12 in the case body 5 are inserted into the second insertion holes 30a, 30a, 30a of the second heat dissipation plate 29, respectively, and the first heat dissipation The plate 25 and the second heat sink 29 are supported by the first mounting portions 11, 11, 11 and the second mounting portions 12, 12, 12, respectively.

Next, the first caulking pins 15, 15, 15 of the first mounting parts 11, 11, 11 are inserted into the first mounting holes 34a, 34a, 34a of the light source board 34, respectively, and the second The second caulking pins 18, 18, 18 of the second attachment parts 12, 12, 12 are inserted into the attachment holes 35a, 35a, 35a, respectively, and the light source board 34 and the control board 35 are inserted into the first attachment parts 11, 11, respectively. , 11 and second mounting portions 12, 12, 12.

Note that the light source board 34 is bonded in advance to the placement surface portion 26 of the first heat sink 25 with a thermally conductive adhesive, and the control board 35 is bonded in advance to the placement surface portion 26 of the first heat sink 25 with a thermally conductive adhesive. It may be bonded to the surface portion 30. In this case, the first caulking pins 15, 15, 15 are inserted into the first insertion holes 26a, 26a, 26a and the first mounting holes 34a, 34a, 34a, respectively, and the second insertion holes 30a, 30a, 30a and the second mounting holes 35a, 35a, 35a, respectively, by inserting the second caulking pins 18, 18, 18, the first heat sink 25 and the light source board 34 are attached to the first mounting portions 11, 11, 11, and the second heat sink 29 and control board 35 are supported by the second mounting parts 12, 12, 12.

By bonding the light source board 34 and the control board 35 to the first heat sink 25 and the second heat sink 29 in advance in this way, the light source board 34 and the first heat sink 25 can be attached to the first mounting portion 11, 11, 11 at the same time, and the control board 35 and the second heat sink 29 can be simultaneously supported by the second mounting parts 12, 12, 12. Therefore, it is possible to shorten the working time and reduce the number of working steps in the assembly work of the vehicle lamp 1.

The first heat sink 25 and the light source board 34 are supported by the first mounting parts 11, 11, 11, and the second heat sink 29 and the control board 35 are supported by the second mounting parts 12, 12, 12. In this state, the connection board 36 is inserted and arranged in the third arrangement space 5c formed between the partition surface section 10 and the other side surface section 9.

Thermal crimping is performed by a first crimping jig 50 and a second crimping jig 60. The first crimping jig 50 applies heat and pressure to the first crimping pin 15 of the first mounting portion 11, and the tip of the first crimping pin 15 is deformed, thereby forming the first heat sink. 25 and the light source board 34 are attached to the first attachment part 11. In addition, the second crimping jig 60 applies heat and pressure to the second crimping pin 18 of the second attachment part 12, and the tip of the second crimping pin 18 is deformed, so that the second crimping pin 18 is heated and pressurized. A heat sink 29 and a control board 35 are attached to the second attachment part 12.

At this time, the first crimping pin 15 is pressurized by the first crimping jig 50, and the second crimping pin 18 is pressurized by the second crimping jig 60. Since the mounting portions 12 of are located on the same straight line, by using the first crimping jig 50 and the second crimping jig 60 at the same time, the second crimping jig 60 becomes the first crimping jig. The first crimping jig 50 also functions as a receiving jig for the pressure applied by the second crimping jig 60. Therefore, the first crimping jig 50 and the second crimping jig 60 apply appropriate pressure to the first crimping pin 15 and the second crimping pin 18, respectively, and without using a dedicated receiving jig. It becomes possible to perform thermal caulking.

The first heat sink 25 and light source board 34 were attached to the first attachment parts 11, 11, 11, and the second heat sink 29 and control board 35 were attached to the second attachment parts 12, 12, 12. In this state, the connector 38 connected to the control board 35 is positioned corresponding to the insertion hole 21b of the front base 21. Further, the first heat sink 25 and the light source board 34 are arranged in the first arrangement space 5a, the second heat sink 29 and the control board 35 are arranged in the second arrangement space 5b, and the first heat sink 25 The light source board 34, the second heat sink 29, and the control board 35 are located on opposite sides of the mounting base 8.

Next, the locking claws 19a, 19a of the locking pieces 19, 19 of the case body 5 are respectively locked to the opening edges of the locking holes 21a, 21a of the cover body 6, so that the case body 5 and the cover body 6 are combined. A lamp housing 2 is constructed. The case body 5 and the cover body 6 are fixed by the mounting screw 70 being inserted into the screw insertion hole 20a of the cover base 20 and screwed into the threaded portion 8a of the mounting base 8 (see FIG. 1).

Subsequently, engagement protrusions 9a, 9a provided on the side surfaces 9, 9 of the case body 5, respectively, are formed at the opening edges of the engagement holes 24a, 24a formed in the coupling surfaces 24, 24 of the cover lens 3, respectively. By being engaged, the cover lens 3 is coupled to the lamp housing 2, and the assembly of the vehicle lamp 1 is completed.

In the vehicle lamp 1, before the case body 5 and the cover body 6 are combined, the cover lens 3 is first combined with the case body 5, and then the case body 5 and the cover body 6 are combined. The assembly of the vehicular lamp 1 may then be completed.

With the vehicle light 1 assembled and attached to the vehicle body as described above, the power cable is connected to the connector 38 through the insertion hole 21a of the front base 21. When a driving current is supplied from a power supply circuit (not shown) to the wiring board 33 via the power cable and the connector 38, the light sources 37, 37, . . . are brought into a state where light can be emitted.

The light sources 37, 37, ... are controlled to turn on and off by the control board 35, and when light is emitted from the light sources 37, 37, ..., the emitted light passes through the cover lens 3 and is directed backward. irradiated. At this time, the light is diffused by the lens steps 24a, 24a, . . . of the cover lens 3, and the light is irradiated.

When the light sources 37, 37 are driven, heat is generated from the light source board 34, the light sources 37, 37, . . . , and the control board 35. The heat generated in the light source board 34 and the light sources 37, 37, ... is transmitted to the first heat sink 25 and released from the first heat sink 25, and the heat generated in the control board 35 is transferred to the second heat sink 29 and is emitted from the second heat sink 29. The heat released from the first heat sink 25 and the second heat sink 29 is released to the outside of the lamp housing 2 from the heat sink holes 20b, 20b, . . . formed in the cover base 20 of the lamp housing 2. .

As described above, in the vehicle lamp 1, the lamp housing 2 has a first mounting part 11 and a second mounting part 11, which protrude from the mounting base 8 in opposite directions and to which the light source board 34 and the control board 35 are respectively attached by thermal caulking. Two attachment parts 12 are provided, and the first attachment part 11 and the second attachment part 12 are located on the same straight line.

Therefore, the first crimping jig 50 and the second crimping jig 60 are used for the first mounting part 11 and the second mounting part 12, which project from the mounting base 8 in opposite directions and are located on the same straight line. It becomes possible to attach the light source board 11 and the control board 12 to the mounting base 8 by pressing them simultaneously from opposite directions. Thereby, the working time in the mounting process of attaching the light source board 34 and the control board 35 to the lamp housing 2 by thermal caulking is shortened, and the workability in the mounting process can be improved.

Further, the first mounting portion 11 has a first base protrusion 13 continuous to the mounting base 8 and a first caulking pin 15 protruding from the distal end surface of the first base protrusion 13. The mounting part 12 has a second base protrusion 16 that is continuous with the mounting base 8 and a second caulking pin 18 that protrudes from the distal end surface of the second base protrusion 16. A first reinforcing rib 14 protruding from the outer circumferential surface of the first base protrusion 13 is provided, and a second reinforcing rib 17 protruding from the outer circumferential surface of the second base protrusion 16 is provided on the second mounting portion 12. is provided.

Therefore, since the strength of the first base protrusion 13 and the second base protrusion 16 is increased by the first reinforcing rib 14 and the second reinforcing rib 17, respectively, the first crimping pin 15 and the second crimping pin 18 When heat crimping is performed by pressing the first crimping jig 50 and the second crimping jig 60 against each other, the first attachment part 11 and the second attachment part 12 are hardly deformed. Thereby, a stable attachment state of the light source board 34 and the control board 35 to the first attachment part 11 and the second attachment part 12 can be ensured.

Furthermore, the lamp housing 2 is formed of a resin material, and a plurality of first reinforcing ribs 14 and second reinforcing ribs 17 are provided spaced apart from each other in the circumferential direction. The position of the second reinforcing rib 17 in the circumferential direction is different from that of the second reinforcing rib 17 in the circumferential direction.

Therefore, since the occurrence of sink marks on the mounting base 8 during molding of the lamp housing 2 is suppressed, it is possible to improve the molding accuracy of the lamp housing 2, and also to prevent the light sources 37, 37, . . . An appropriate light distribution state can be ensured by improving positional accuracy.

Furthermore, the first heat dissipation plate 25 has a first insertion hole 26a into which the first crimping pin 15 is inserted, and is attached to the first mounting portion 11 in contact with the light source board 34, and a second crimping pin. A second heat dissipation plate 29 is provided, which has a second insertion hole 30a through which the heat sink 18 is inserted, and is attached to the second attachment portion 12 in contact with the control board 35.

Therefore, when the first crimping jig 50 is pressed against the first crimping pin 15 to perform thermal crimping, the first heat sink 25 is attached to the first mounting portion 11 in addition to the light source board 34 at the same time. When the second crimping jig 60 is pressed against the second crimping pin 18 to perform thermal crimping, the second heat sink 29 is attached to the second mounting portion 12 in addition to the control board 35 at the same time. As a result, there is no need to perform the mounting work of the light source board 34 and the control board 35 and the mounting work of the first heat sink 25 and the second heat sink 29 separately, and it is possible to improve workability in the mounting work. can.

In addition, the first heat sink 25 and the second heat sink 29 are located on opposite sides of the mounting base 8.

Therefore, when the light sources 37, 37, . , 37, . . . and the driving state of the control board 35 is hardly affected, so that a stable driving state of the light sources 37, 37, . . . can be ensured.

In the above-described assembly work of the vehicle lamp 1, the same number of first crimping jigs 50 and second crimping jigs 60 as the number of first mounting parts 11 and second mounting parts 12 are used. Good too. For example, if three first mounting parts 11, 11, 11 and second mounting parts 12, 12, 12 are provided as described above, three first crimping jigs are provided. Using the first crimping jigs 50, 50, 50 and the second crimping jigs 60, 60, 60, the first crimping jigs are applied to the first mounting parts 11, 11, 11 and the second mounting parts 12, 12, 12, respectively. Heating and pressurization are performed simultaneously by the tools 50, 50, 50 and the second crimping jigs 60, 60, 60.

By performing such work, the work time in the installation process of attaching the light source board 34 and the control board 35 to the lamp housing 2 by thermal caulking can be significantly shortened, and the workability in the installation process can be further improved. .
