Fig. 1 is a schematic front view of a vehicle lamp 10 according to an embodiment. Fig. 2 is a schematic view showing a horizontal cross section of a line a-a of the vehicle lamp 10 shown in fig. 1.

The vehicle lamp 10 is a vehicle headlamp device having a pair of headlamp units disposed on the left and right sides in front of a vehicle. Since the pair of headlamp units have a substantially bilaterally symmetric structure and substantially the same structure, fig. 1 and 2 show the vehicle lamp positioned on the left side as viewed from the front of the vehicle. Thus, in fig. 1 and 2, the left side is located on the outside in the vehicle width direction, and the right side is located on the inside in the vehicle width direction.

The vehicle lamp 10 includes: a lamp body 12 having a front surface opening 13; and a front surface cover 14 mounted on the lamp body 12 so as to cover the front surface opening 13. The lamp body 12 is configured to be attachable to a vehicle body, and the front cover 14 is attached to the vehicle body via the lamp body 12. The lamp body 12 and the front cover 14 constitute a lamp housing, and an internal space of the lamp housing is formed as a lamp chamber 16. The lamp body 12 is formed of, for example, a resin material. The front surface opening 13 is open to the vehicle front side. The front cover 14 is made of a light-transmitting resin, glass, or the like.

The vehicle lamp 10 includes a movable lamp unit 18 and a fixed lamp unit 20, and the movable lamp unit 18 and the fixed lamp unit 20 are disposed in the lamp chamber 16. As one example, the movable light unit 18 functions as a head light and the fixed light unit 20 functions as a width light and/or daytime running light or as other identification lights. As a non-limiting example, the movable lamp unit 18 is disposed on the outside in the vehicle width direction, and the fixed lamp unit 20 is disposed on the inside in the vehicle width direction.

The movable lamp unit 18 is supported by the lamp body 12 so as to be movable relative to the lamp body 12. Specifically, for example, the movable lamp unit 18 is supported by the lamp body 12 so as to be swingable with respect to the lamp body 12, and the optical axis is adjusted. The fixed lamp unit 20 is fixedly supported with respect to the lamp body 12. Thus, the fixed lamp unit 20 does not move relative to the lamp body 12.

As shown in fig. 2, the vehicle lamp 10 includes: a bracket 22 disposed in front of the lamp body 12; and a wire harness 24 mounted to the bracket 22. The movable lamp unit 18 and the fixed lamp unit 20 are adjacent to each other and disposed in front of the bracket 22.

The holder 22 has: a front surface 22a facing the front surface cover 14 side; and a rear surface 22b facing the lamp body 12 side. A part (for example, the outer half in the vehicle width direction) of the bracket 22 is located behind the movable lamp unit 18, and another part (the inner half in the vehicle width direction) of the bracket 22 is located behind the fixed lamp unit 20. The rear surface 22b of the holder 22 is opposed to the back of the lamp body 12. The holder 22 is formed of, for example, a resin material. The support 22 may also be referred to as a wiring support or body side support.

The holder 22 may be a partition plate that divides the lamp chamber 16 into a rear space 40 and a front space 42. The rear space 40 is the area between the bracket 22 and the lamp body 12. The rear space 40 may accommodate a majority of the wiring harness 24. The front space 42 is a region between the bracket 22 and the front cover 14, and the movable lamp unit 18 and the fixed lamp unit 20 are arranged.

Although details are described later, the wire harness 24 is provided on the rear surface 22b of the bracket 22 behind the movable lamp unit 18, and extends from the rear surface 22b of the bracket 22 to the front surface 22a behind the fixed lamp unit 20. The bracket 22 has an opening 23 located behind the fixed lamp unit 20. The wire harness 24 is arranged on the rear surface 22b of the bracket 22, and is guided from the rear surface 22b of the bracket 22 to the front surface 22a through the opening portion 23. Hereinafter, the harness 24 is sometimes referred to as the 1 st harness 24 for distinction from other harnesses.

The 1 st connector 24a of the 1 st wire harness 24 is connected to the connector of the 2 nd wire harness 26. The 2 nd wire harness 26 connects the 1 st wire harness 24 with an external electronic device 27 that controls the vehicle lighting 10. The external electronic device 27 is disposed outside the lamp chamber 16. The external electronic device 27 is, for example, a lamp ECU, and is disposed outside the bottom of the lamp body 12.

In addition, the bracket 22 has a connector retaining structure 28. The connector holding structure 28 is configured to hold both connectors at predetermined positions when the connectors of the harnesses (for example, the 1 st connector 24a of the 1 st harness 24) are regularly fitted with the counterpart connector (for example, the connector of the 2 nd harness 26), and to be located at positions deviated from the predetermined positions when the connectors are half fitted. Details of the connector 28 are described later.

The vehicle lamp 10 further includes a blower 30 provided in the bracket 22. The blower 30 has an outlet 30a at the front surface 22a of the bracket 22. The bracket 22 includes a flow straightening plate 32 formed at least in part around the outlet port 30a so that the air flow blown out from the outlet port 30a is directed toward the movable lamp unit 18. Details of the rectifying plate 32 are also described later in detail.

Fig. 3 and 4 are schematic perspective views showing the holder 22 according to the embodiment. Fig. 3 shows a front surface 22a of the bracket 22, and fig. 4 shows a rear surface 22b of the bracket 22.

In addition to the blower 30, several devices, such as a leveling actuator 34,

internal electronics

36a, 36b, are provided on the rear surface 22b of the bracket 22. The blower 30 and the leveling actuator 34 are disposed on the bracket 22 at positions rearward of the movable lamp unit 18. The blower 30 is located below the bracket 22 and the leveling actuator 34 is located above the bracket 22. The

internal electronics

36a, 36b are mounted to the rear surface 22b of the bracket 22 at a location where the rear of the fixed light unit 20 is located. When the bracket 22 is attached to the lamp body 12, the blower 30, the leveling actuator 34, and the internal

electronic devices

36a and 36b are supported by the bracket 22 and are disposed in the rear space 40 between the bracket 22 and the lamp body 12.

The leveling actuator 34 includes a leveling shaft 38, and the leveling shaft 38 extends forward of the bracket 22 from the leveling actuator 34. The leveling shaft 38 can be advanced and retracted by driving the leveling actuator 34. The internal

electronic devices

36a and 36b are, for example, control circuit boards for controlling the stationary lamp unit 20. At least one of the internal

electronic devices

36a, 36b may be configured to control the movable lamp unit 18, and may be a sensor, a camera, or another electronic device.

Fig. 3 and 4 show the bracket 22 and the 1 st wire harness 24. The 1 st harness 24 includes a plurality of connectors 24a to 24 g. The 1 st harness 24 extends from the 1 st connector 24a, branches into a plurality of electric wires on the way, and the other connectors 24b to 24g are provided at the ends of the electric wires.

The 1 st connector 24a, the 2 nd connector 24b, and the 3 rd connector 24c are arranged on the front surface 22a side of the holder 22. As described above, the 1 st connector 24a is connected to the 2 nd wire harness 26. The 2 nd connector 24b is provided for connecting the 1 st wire harness 24 to the movable lamp unit 18. The 3 rd connector 24c is provided for connecting the 1 st wire harness 24 to the stationary lamp unit 20.

The 4 th, 5 th, 6 th, and 7

th connectors

24d, 24e, 24f, and 24g are arranged on the rear surface 22b side of the holder 22. The 4 th connector 24d is connected to the blower 30 and the 5 th connector 24e is connected to the leveling actuator 34. The 6 th connector 24f is connected to the internal electronic device 36a, and the 7 th connector 24g is connected to the internal electronic device 36 b.

The 1 st wire harness 24 has a plurality of electric wire clamps 44 spaced apart from each other and arranged along the electric wires, and these electric wire clamps 44 are fixed to the rear surface 22b side of the bracket 22.

Fig. 5(a) to 5(c) are schematic diagrams for explaining the connector holding structure 28 according to the embodiment. The connector retaining structure 28 includes a protrusion or a recess formed in a surface (e.g., the front surface 22a or the rear surface 22b) of the bracket 22. The connector retaining structure 28 is set to the following shape: these connectors are held at predetermined positions when 2 connectors connected to each other are normally fitted. The connector holding structure 28 is configured such that the 2 connectors are located at positions deviated from predetermined positions when the connection is incomplete (so-called half-fitting). In other words, the shape and size of the connector holding structure 28 are set such that when the connection of 2 connectors is incomplete, the combination of the two connectors will not be received into the connector holding structure 28.

In fig. 5(a), a state is shown in which 2 connectors (for example, the 1 st connector 24a of the 1 st wire harness 24 and the counterpart connector 26a of the 2 nd wire harness 26) are normally fitted, and thus the 1 st wire harness 24 and the 2 nd wire harness 26 are completely connected. One of the 2 connectors is a male connector, and the other is a female connector. One of the connectors, for example, the 1 st connector 24a has a mounting portion 46, and is fixed to the holder 22 by the mounting portion 46. The mounting portion 46 defines a reference position 48. In order to facilitate the connection of the 2 connectors, the mounting portion 46 is configured such that the fixed connector can move slightly relative to the bracket 22.

As shown in fig. 5(a), the connector holding structure 28 has a connector holding projection 50 formed on the surface of the holder 22. The distance P represents a distance from the reference position 48 to the connector holding projection 50, and the distance Q represents a distance from the reference position 48 to the end surface 52 of the mating connector 26a when 2 connectors are normally fitted. Here, the electric wires extend from the end face 52. The connector retention structure 28 is designed such that the distance P is equal to the distance Q. That is, the connector holding projection 50 is formed on the surface of the holder 22 in such a manner that the distance P is equal to the distance Q. Thus, when the 2 connectors are mated together, the connectors are just received into the connector retention structure 28.

However, as shown in fig. 5(b), when 2 connectors are not tightly connected, the distance R from the reference position 48 to the end surface 52 of the mating connector 26a is longer than the distance Q. Thus, the distance R is longer than the distance P. Therefore, the joint of the 2 connectors is prevented by the connector holding projection 50 and is not received in the connector holding structure 28. In this way, the 2 connectors in the half-fitted state are deviated from the connector holding structure 28. The worker can easily confirm the half fitting of the connector by visual observation. In this case, the operator can reconnect the connector and fit it in a standard manner.

As shown in fig. 5(c), the connector holding structure 28 may also have a connector holding recess 53 formed in the surface of the holder 22. For example, one end of the connector holding recess 53 may be used as the reference position 48. Likewise, the connector holding structure 28 (i.e., the shape and size of the connector holding recess 53) may also be designed such that: the distance P from the reference position 48 to the other end of the connector holding recess 53 is equal to the distance Q corresponding to the length of 2 connectors to be fit regularly.

Such connector holding structures 28 are not limited to a specific 2 connectors, and may be provided on the front surface 22a and/or the rear surface 22b of the holder 22 for any 2 connectors. Alternatively, the connector holding structure 28 may be provided on an arbitrary wall surface or an arbitrary surface of a component in the vehicle lamp 10, if necessary.

Fig. 6 is a schematic view showing a vertical cross section of the vehicle lamp 10 shown in fig. 1 along line B-B. Referring to fig. 6, the rectifying plate 32 is further explained.

As shown in fig. 6, the movable lamp unit 18 includes a plurality of sub-assemblies (18a to 18 c). The plurality of subassemblies are fixed in position relative to one another. As a non-limiting example, the movable lamp unit 18 includes 3 sub-assemblies, hereinafter also referred to as a 1 st sub-assembly 18a, a 2 nd sub-assembly 18b, and a 3 rd sub-assembly 18c, which are arranged in a stepped manner. That is, the uppermost 1 st subassembly 18a is disposed at the rearmost, and the lowermost 3 rd subassembly 18c is disposed at the foremost.

Each subassembly includes a light emitting element mounting portion 54 having a heat radiating portion 56. Each subassembly includes a light source 58 and at least one optical component (e.g., a reflector 60 and a projection lens 62).

The light emitting element mounting portion 54 provides a support surface for supporting the light source 58, and is formed integrally with the heat radiating portion 56. The heat radiating section 56 includes a plurality of heat radiating fans extending rearward from the light emitting element mounting section 54. The heat radiation fans may be parallel to the vertical plane. The light emitting element mounting portion 54 and the heat radiating portion 56 also function as a heat radiating member for radiating heat generated by the light source 58, and are also referred to as a heat sink. The light emitting element mounting portion 54 and the heat radiating portion 56 are formed of a metal material having high thermal conductivity, such as aluminum or an aluminum alloy, and are manufactured by, for example, die casting. The light emitting element mounting portion 54 is configured to support the reflector 60 and the projection lens 62.

The light source 58 includes a semiconductor light emitting element 58a such as a Light Emitting Diode (LED) and a substrate 58b supporting the semiconductor light emitting element 58 a. The substrate 58b is a heat conductive insulating substrate formed of ceramic or the like. An electrode (not shown) for transmitting power to the semiconductor light emitting element 58a is formed on the substrate 58 b. The light source 58 is mounted on the light emitting element mounting portion 54 in a state where the light emitting surface of the semiconductor light emitting element 58a faces upward of the vehicle and the irradiation axis of the semiconductor light emitting element 58a extends substantially in the vertical direction of the vehicle.

The reflector 60 is disposed above the light source 58 to reflect the light emitted from the light source 58 toward the projection lens 62. The reflector 60 is a reflecting member, and the inner surface thereof facing the light source 58 is formed as a reflecting surface, and the reflecting surface is formed by a part of a surface of revolution ellipse, for example. In addition, the projection lens 62 is disposed in front of the light source 58 to project the reflected light from the reflector 60 toward the front of the lamp. As an example, the projection lens 62 is a plano-convex aspherical lens whose front side surface is a convex surface and rear side surface is a flat surface, and is formed of a transparent resin material.

The movable lamp unit 18 is not limited to the above-described specific example, and other known configurations may be appropriately employed.

As described above, the blower 30 is provided on the bracket 22 and behind the movable lamp unit 18. The blower 30 has an air outlet 30a on the front surface 22a of the bracket 22, and an air inlet 30b on the rear surface 22b of the bracket 22. Accordingly, the air inlet 30b sucks air from the rear space 40, and the air outlet 30a blows out air into the front space 42. The blower 30 may be, for example, an axial fan, or a thin fan attached to a blower attachment hole of the bracket 22. Blower 30 is disposed at substantially the same height as that of subassembly 3 c, and outlet 30a is located behind subassembly 3 c.

The flow straightening plate 32 is provided below the outlet 30a along the periphery of the outlet 30 a. The flow rectification plate 32 is provided across, for example, 1/2 to 1/4 in the entire circumference of the blow-out port 30 a. The current plate 32 is formed integrally with the bracket 22 as a part of the bracket 22, and extends forward from the front surface 22a of the bracket 22. The current plate 32 is located below the movable lamp unit 18, i.e., below the 3 rd sub-assembly 18c, and is located near the bottom of the lamp body 12, since it is located below the blower 30. In order to suppress the flow of air passing between the lower surface of the current plate 32 and the lamp body 12, the gap between the current plate 32 and the bottom of the lamp body 12 is preferably as small as possible (for example, 5mm or less). Since the outlet 30a is circular, the flow straightening plate 32 may have another shape such as a flat plate, although it is cylindrically curved.

An opening 64 for promoting circulation of air by the blower 30 is provided above the blower 30 in the holder 22. Air can flow from the front space 42 to the rear space 40 through the opening 64.

As shown in fig. 6, blower 30 generates an air flow 66 (indicated by solid arrows) within lamp chamber 16. The air flow 66 is sent out from the outlet 30a of the blower 30 to the front space 42. Since the flow rectification plate 32 is provided below the blow-out port 30a, the flow toward the lower side of the flow rectification plate 32 is suppressed, and the airflow 66 flows forward and upward. The air flow 66 is blown to the heat radiating portions 56 of the subassemblies (18a to 18 c). The air flow 66 passes near the heat radiating portion 56 while exchanging heat with the heat radiating portion 56, and takes heat from the heat radiating portion 56.

The air flow 66 thus cooled by the heat radiating portion 56 is returned to the rear space 40 through the opening portion 64. The blower 30 sucks air in the rear space 40 from the air suction hole 30b, and the air flow 66 is sent out to the front from the blower 30 again.

Thus, the cooling efficiency of the vehicle lamp 10 is improved by providing the current plate 32. Further, since the rectifying plate 32 is formed integrally with the holder 22, the manufacturing cost can be reduced as compared with a case where the rectifying plate 32 is prepared as a separate member.

The arrangement of the rectifying plate 32 is not limited to the lower side of the air outlet 30a, and may be formed in a part of the periphery of the air outlet 30a, such as above or on the side of the air outlet, depending on the positional relationship between the movable lamp unit 18 and the blower 30. If necessary, the flow straightening plate 32 may surround the entire periphery of the outlet port 30 a.

Fig. 7 to 12 are schematic perspective views showing respective steps of the method of manufacturing the vehicle lamp 10 according to the embodiment. First, the lamp body 12 is prepared as shown in fig. 7 and 10. The lamp body 12 is provided with 2 adjustment screws 68 used in adjusting the optical axis of the movable lamp unit 18. The 2 adjusting screws 68 are arranged side by side in the horizontal direction. Further, a bracket 22 (see fig. 3 and 4) to which the 1 st wire harness 24 is attached is prepared. The blower 30, the leveling actuator 34, and the internal

electronic devices

36a and 36b are mounted on the bracket 22, and these components are connected to the 1 st harness 24 in advance.

As shown in fig. 8 and 11, a holder 22 is disposed in front of the lamp body 12. The holder 22 is fixed to the lamp body 12 by an appropriate method such as screwing. In addition, an external electronic device 27 is mounted on the bottom surface of the lamp body 12. The 1 st connector 24a of the 1 st wire harness 24 is connected with the counterpart connector 26a of the 2 nd wire harness 26 extending from the external electronic device 27. The connected 1 st connector 24a and the mating connector 26a are just received into the connector retaining structure 28 on the bracket 22.

Since the bracket 22 fixes the front surface 22a to the lamp body 12 in the forward direction, the 1 st connector 24a of the 1 st wire harness 24 is arranged on the front side of the operator. This facilitates the connection operation between the 1 st connector 24a and the mating connector 26 a. Similarly, since the 2 nd connector 24b and the 3 rd connector 24c are arranged on the near side, the subsequent connection work is easy. Most of the 1 st wire harness 24 including the other connectors (24d to 24g) and the respective devices connected to these connectors in advance are housed between the bracket 22 and the lamp body 12 because they are attached to the rear surface 22b of the bracket 22. Thus, these devices and the wire harness do not hinder the subsequent work.

In addition, 2 adjustment screws 68 of the lamp body 12 are positioned at both sides of the blower 30. The leveling shaft 38 is located above the one of the 2 leveling screws 68 located on the vehicle width direction inner side in the vertical direction of the leveling screw 68.

Next, as shown in fig. 9 and 12, the movable lamp unit 18 is disposed in front of the bracket 22. At this time, the movable lamp unit 18 is supported by the lamp body 12 so as to be supported by 3 support points in total of the 2 adjustment screws 68 and the leveling shaft 38. The leveling actuator 34 can swing the movable lamp unit 18 with respect to the lamp body 12 by moving the leveling shaft 38 forward and backward. The 2 nd connector 24b of the 1 st wire harness 24 is connected to the 3 rd wire harness 70 on the movable lamp unit 18 side.

Next, the fixed lamp unit 20 is disposed in front of the bracket 22 adjacent to the movable lamp unit 18. The fixed lamp unit 20 is fixed to the lamp body 12 by an appropriate method such as screwing. The 1 st wire harness 24 is provided on the rear surface 22b of the bracket 22 behind the movable lamp unit 18, and extends from the rear surface 22b of the bracket 22 to the front surface 22a behind the fixed lamp unit 20. The 3 rd connector 24c of the 1 st wire harness 24 is connected to the wire harness on the side of the fixed lamp unit 20. Then, the front surface cover 14 is mounted on the lamp body 12. As a result, the vehicle lamp 10 is obtained as shown in fig. 1 and 2.

As described above, the majority of the 1 st wire harness 24 is mounted on the rear surface 22b of the bracket 22. When the bracket 22 is mounted to the lamp body 12, a portion of the 1 st wire harness 24 mounted to the rear surface 22b of the bracket 22 is accommodated in the rear space 40 between the bracket 22 and the lamp body 12. The 1 st wire harness 24 is guided from the rear surface 22b of the bracket 22 through the opening portion 23 to the front surface 22 a. The remaining portion of the 1 st harness 24 including the 1 st connector 24a, the 2 nd connector 24b, and the 3 rd connector 24c is disposed in the front space 42. However, the remaining portion of the 1 st wire harness 24 is disposed behind the fixed lamp unit 20, and therefore, is disposed outside the movable range of the movable lamp unit 18.

The movable lamp unit 18 and the fixed lamp unit 20 are connected to an external electronic device 27 via a 1 st wire harness 24 and a 2 nd wire harness 26. Similarly, the devices such as the blower 30 provided in the rack 22 are also connected to the external electronic device 27 via the 1 st harness 24 and the 2 nd harness 26. Thereby, the vehicle lamp 10 can be supplied with power via the external electronic device 27 and controlled by the external electronic device 27.

As described above, according to the vehicle lamp 10 according to the embodiment, the 1 st wire harness 24 is provided on the rear surface 22b of the bracket 22 behind the movable lamp unit 18, and extends from the rear surface 22b of the bracket 22 to the front surface 22a behind the fixed lamp unit 20. Therefore, the 1 st wire harness 24 can be arranged by the bracket 22 so as to avoid the movable range of the movable lamp unit 18. Therefore, the risk of damage or disconnection of the 1 st wire harness 24 due to interference between the movable lamp unit 18 and the 1 st wire harness 24 can be reduced, and the 1 st wire harness 24 can be protected.

The 3 rd wire harness 70 is arranged between the movable lamp unit 18 and the bracket 22. In this way, a part of the wiring may be arranged around the movable lamp unit 18. However, according to the present embodiment, since the other wires such as the 1 st harness 24 are arranged so as to avoid the movable range of the movable lamp unit 18, the wires arranged around the movable lamp unit 18 can be limited to the minimum necessary. By arranging the wiring in this manner, the risk of damage or disconnection of the wiring due to interference that may occur between the wiring and the movable lamp unit can be reduced, and the wiring in the vehicle lamp 10 can be protected.

In addition, the connector holding structure 28 is configured to hold both connectors at predetermined positions when the connectors of the wire harness are regularly fitted with the counterpart connectors, and to be located at positions deviated from the predetermined positions when both connectors are half fitted. Thus, the half fitting can be easily found and corrected at once during the connection operation of the connector. Therefore, a dedicated process for inspecting the half-fitted product can be omitted from the manufacturing process of the vehicle lamp 10. This can contribute to reduction in manufacturing cost of the vehicular lamp 10.

The bracket 22 includes a flow straightening plate 32 formed at least in part around the outlet port 30a so that the air flow blown out from the outlet port 30a is directed toward the movable lamp unit 18. This suppresses a local circulating flow that may occur at a position very close to the blower 30, and increases the air flow toward the movable lamp unit 18 and the fixed lamp unit 20, thereby improving the cooling efficiency of the vehicle lamp 10.

The present invention is not limited to the above-described embodiments and modifications, and may be combined with the embodiments and modifications, or further modified by various design changes based on the knowledge of those skilled in the art, and the embodiments and modifications to which such combinations or further modifications are applied are also included in the scope of the present invention. The new embodiments resulting from the combination of the above-described embodiment, modification example, and modification below have the respective effects of the combined embodiment, modification example, and further modification.

The above-described embodiment has been described taking the vehicle lamp 10 as an example of the vehicle headlamp apparatus, but the present invention is not limited to this. The wiring support bracket according to the embodiment is not limited to being applied to a headlamp, and can be applied to other vehicle lamps such as a tail lamp, a turn signal lamp, and a brake lamp.
