Description

[Technical Field]

[0001] The present invention relates to a vehicle-mounted component and a vehicle lamp. [Background technology]

[0002] For example, a vehicle lamp mounted on a vehicle has a structure in which components such as a light source, inner lens, reflector, extension, and bracket are arranged inside a lamp body made up of a housing with an opening at the front and an outer lens that covers the opening of the housing, and these components are attached to the inside of the lamp body (see, for example, Patent Document 1 below).

[0003] Specifically, Patent Document 1 below describes a light guide that is attached to a reflector, and that emits light by reflecting light incident on an entrance surface at a longitudinal end along the longitudinal direction while totally reflecting the light, at a cut surface formed on the back surface, and emitting the reflected light forward from an exit surface formed on the front surface.The light guide is attached to the reflector by having an attachment rib protruding toward the back surface and engaging a hook or hook formed in the attachment rib with a hook or hook hole formed in the reflector.

In the drawings used in the following description, the dimensions of the components may be shown at different scales to make them easier to see, and the dimensional ratios of the components may not necessarily be the same as in reality.

[0012] As one embodiment of the present invention, a vehicle lamp 100 including a vehicle-mounted component 1 shown in, for example, FIGS. 1 to 6 will be described.

[0013] FIG. 1 is a front view showing a vehicle lamp 100 equipped with a vehicle-mounted component 1. FIG. 2 is a perspective view of the vehicle-mounted component 1. FIG. 3 is an exploded perspective view of the vehicle-mounted component 1. FIG. 4 is a top view of the vehicle-mounted component 1. FIG. 5 is a cross-sectional view of the vehicle-mounted component 1 taken along line AA shown in FIG. 4. FIG. 6 is a cross-sectional view of the vehicle-mounted component 1 taken along line BB shown in FIG. 4.

[0014] In addition, in the drawings shown below, an XYZ Cartesian coordinate system is set up, with the X-axis direction representing the front-to-rear direction (length direction) of the vehicle lighting fixture 100, the Y-axis direction representing the left-to-right direction (width direction) of the vehicle lighting fixture 100, and the Z-axis direction representing the up-to-down direction (height direction) of the vehicle lighting fixture 100.

[0015] 1, the present embodiment of the vehicle lamp 100 is a front combination lamp mounted on both corners of the front end of a vehicle, for example. In this embodiment, the vehicle lamp 100 mounted on the corner on the right front end will be illustrated and described.

[0016] The vehicle lamp 100 of this embodiment includes a lamp unit 102 arranged inside a lamp body 101 and a distance image sensor 103 mounted on the front side of the lamp body 101.

[0017] The lamp body 101 is composed of a housing with an opening at the front and a transparent outer lens that covers the opening of the housing. The shape of the lamp body 101 can be changed as needed to suit the design of the vehicle.

[0018] The lighting unit 102 has a low beam lamp 104 that emits a low beam toward the front of the vehicle, a high beam lamp 105 that emits a high beam toward the front of the vehicle, a position lamp 106 that emits white light, and a turn lamp 107 that flashes with orange light.

[0019] In the vehicle lighting device 100 of this embodiment, a low beam lamp 104 located on the inside in the vehicle width direction and a high beam lamp 105 located on the outside in the vehicle width direction are arranged side by side in the vehicle width direction. In addition, a position lamp 106 and a turn lamp 107 are arranged side by side in the vehicle width direction above and outside the high beam lamp 105 in the vehicle width direction. The distance image sensor 103 is arranged below and outside the high beam lamp 105 in the vehicle width direction.

[0020] The vehicle lighting device 100 is not necessarily limited to this configuration, and the arrangement and shape of the lamps 104 to 107 and the distance image sensor 103 can be changed as appropriate to suit the design of the vehicle.

[0021] In addition to the above-mentioned lamp unit 102, components such as extensions and brackets are arranged inside the lamp body 101, and these components are attached to the inside of the lamp body 101 to form the above-mentioned front combination lamp.

[0022] The distance image sensor 103 constitutes the vehicle-mounted component 1 of this embodiment as shown in, for example, FIGS.

[0023] Specifically, this vehicle-mounted component 1 has a housing 4 composed of a case 2 having an opening 2a on the front side and a cover lens 3 that closes the opening 2a of the case 2, and has a configuration in which a sensor unit 5 that employs a method such as LiDAR (Light Detection And Ranging) or TOF (Time of Flight) is arranged inside this housing 4.

[0024] The housing 4 is attached integrally with the outer lens, with the case 2 embedded in a recess provided in the outer lens on the front side of the lamp body 101 shown in Fig. 1. The cover lens 3 is also positioned so as to be flush with the front side of the outer lens.

[0025] In the vehicle-mounted component 1, a cover lens 3, which is a second member, is detachably attached to the front side of a case 2, which is a first member. This makes it possible to replace a sensor unit 5, which is a replaceable part arranged inside a housing 4.

[0026] The case 2 has a bottom wall portion 2b that forms the back side of the housing 4, an outer peripheral wall portion 2c that rises forward from around the bottom wall portion 2b, and an inner peripheral wall portion 2d that rises forward from the inside of the outer peripheral wall portion 2c, and is formed into a roughly rectangular box shape overall, with the front end portion of the inner peripheral wall portion 2d opening as an opening 2a.

[0027] The cover lens 3 has a top wall portion 3a that forms the front side of the housing 4, and a peripheral wall portion 3b that rises from the periphery of the top wall portion 3a toward the rear side, and is formed in a generally rectangular lid shape overall.

[0028] The housing 4 is configured such that the peripheral wall portion 3b of the cover lens 3 is fitted between the outer peripheral wall portion 2c and the inner peripheral wall portion 2d of the case 2, thereby causing the cover lens 3 to close the opening 2a of the case 2.

[0029] The vehicle-mounted component 1 of this embodiment has a first locking portion 7 provided on a first opposing portion 6 facing the cover lens 3 of the case 2, and a second locking portion 9 provided on a second opposing portion 8 of the cover lens 3 facing the case 2, and has a hook-fastening structure in which the first locking portion 7 and the second locking portion 9 are locked together, thereby providing an attachment structure in which the cover lens 3 is attached to the front side of the case 2.

[0030] In the vehicle-mounted component 1 of this embodiment, two hook fastening structures are provided on the upper sides of the case 2 and the cover lens 3, which are symmetrical to each other.

[0031] In the vehicle-mounted component 1 of this embodiment, the hook fastening structures can be provided not only on the upper sides of the case 2 and the cover lens 3 but also on the lower sides and both left and right side surfaces of the case 2 and the cover lens 3, as necessary. In addition, the number and intervals at which the hook fastening structures are arranged can also be changed as appropriate.

[0032] The first opposing portion 6 has a flat plate shape and is disposed with a gap S between it and the upper outer peripheral wall portion 2c of the case 2. The first opposing portion 6 is formed integrally with the case 2 via a connecting portion 2e that connects the end portion on the rear side and the upper outer peripheral wall portion 2c.

[0033] A plurality of first locking portions 7 (two in this embodiment) are provided side by side in the longitudinal direction (vehicle width direction) of the first opposing portion 6. In this embodiment, the first locking portions 7 are configured by claw portions (locking protrusions) protruding from the surface (lower surface) of the first opposing portion 6 that faces the second opposing portion 8.

[0034] The first opposing portion 6 has a pair of first notches 10 located on both sides of the first engaging portion 7, an elastic piece 11 located between the pair of first notches 10, a second notch 12 located on the base end side of the elastic piece 11, a pair of third notches 13 located on both sides of the second notch 12 and outside the pair of first notches 10, and a pair of fourth notches 14 located outside the pair of third notches 13.

[0035] Of these, the pair of first notches 10 and the pair of fourth notches 14 are formed so as to cut out the first opposing portion 6 from the end on the rear side toward the front side, while the second notch 12 and the pair of third notches 13 are formed so as to cut out the first opposing portion 6 from the end on the front side toward the rear side.

[0036] As a result, a serpentine portion 6a is formed in the first opposing portion 6, which serpentines between the pair of first notches 10 and the pair of fourth notches 14 and the second notch 12 and the pair of third notches 13.

[0037] The elastic piece 11 is formed by a portion that protrudes toward the rear side from between the pair of first cutout portions 10. This allows the elastic piece 11 to form a flexible portion that can be elastically displaced toward the opposite side (upward) from the side facing the second facing portion 8. The first locking portion 7 is provided at a position facing the second locking portion 9 on the tip side of the elastic piece 11.

[0038] The second opposing portion 8 has a flat plate shape and is provided so as to protrude rearward from the outside of the peripheral wall portion 3b. The second opposing portion 8 is provided so as to be able to enter the gap S between the first opposing portion 6 and the front side of the case 2. The second opposing portion 8 is also able to penetrate the gap S and protrude rearward beyond the end of the first opposing portion 6 on the rear side. Therefore, the connecting portions 2e of the first opposing portion 6 are provided on both sides of the second opposing portion 8.

[0039] Furthermore, the width W2 of the second opposing portion 8 is larger than the width W1 of the elastic piece 11, and the width W2 of the second opposing portion 8 is smaller than the width W3 of the meandering portion 6a of the first opposing portion 6.

[0040] A plurality of second locking portions 9 (two in this embodiment) are arranged side by side in the longitudinal direction (vehicle width direction) of the second opposing portion 8. In this embodiment, the second locking portions 9 are configured as hole portions (locking recesses) penetrating the surface (upper surface) of the second opposing portion 8 facing the first opposing portion 6. Note that the locking recesses are not limited to the above-mentioned hole portions, and may be holes formed by recessing the surface (upper surface) of the second opposing portion 8 facing the first opposing portion 6.

[0041] In the vehicle-mounted component 1 of this embodiment having the above-described configuration, when the cover lens 3 closes the opening 2a of the case 2, the second opposing portion 8 enters the gap S between the first opposing portion 6 and the cover lens 3 from the front side of the case 2, and the first locking portion 7 and the second locking portion 9 are locked to each other. This allows the cover lens 3 to be attached to the front side of the case 2.

[0042] On the other hand, in the vehicle-mounted component 1 of this embodiment, the engagement between the first engaging portion 7 and the second engaging portion 9 is released by elastically displacing (flexibly deforming) the elastic piece 11 from the front side of the case 2 toward the opposite side (upward) from the side facing the second opposing portion 8. This allows the cover lens 3 to be removed from the front side of the case 2.

[0043] As described above, in the vehicle-mounted component 1 of this embodiment, by providing the serpentine portion 6a formed by the first to fourth notches 10, 12, 13, and 14 in the first opposing portion 6 described above, it is possible to ensure an elastic displacement amount (flexural deformation amount) of the elastic piece 11 sufficient to release the engagement state between the first engagement portion 7 and the second engagement portion 9.

[0044] Furthermore, in the vehicle-mounted component 1 of this embodiment, even from the front side of the case 2, it is possible to make it easier for the elastic piece 11 to be elastically displaced (flexibly deformed) from the base end side of the elastic piece 11 where the above-mentioned second cutout portion 12 is located toward the opposite side (upper side) from the side facing the second opposing portion 8 through the gap S between the first opposing portion 6 and the second opposing portion 8.

[0045] Therefore, in the vehicle-mounted component 1 of this embodiment, the first locking portion 7 provided on the first opposing portion 6 and the second locking portion provided on the second opposing portion 8 are locked to each other, so that in an attachment structure in which the cover lens 3 is attached to the front side of the case 2, the locked state between the first locking portion 7 and the second locking portion 9 can be released from the front side of the case 2, and the cover lens 3 can be easily removed from the case 2.

[0046] Furthermore, in the vehicle-mounted component 1 of this embodiment, it is possible to prevent plastic deformation and breakage of the elastic piece 11 even when the cover lens 3 is repeatedly attached to and detached from the case 2. That is, by providing the serpentine portion 6a in the first opposing portion 6 described above, it is possible to make the amount of elastic displacement (amount of deflection deformation) of the elastic piece 11 required to release the locked state between the first locking portion 7 and the second locking portion 9 smaller than the amount of displacement of the elastic piece 11 when a yield stress (plastic deformation) is applied to the elastic piece 11.

[0047] The present invention is not necessarily limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, in the mounting structure of the vehicle-mounted component 1, the locking protrusions such as the claws constituting the first locking portion 7 described above are configured to lock into the locking recesses such as holes or holes constituting the second locking portion 9, but the opposite configuration, i.e., the locking protrusions such as the claws constituting the second locking portion 9 are formed in the locking recesses such as holes or holes constituting the first locking portion 7, may also be used as long as the first locking portion 7 and the second locking portion 9 are configured to be able to lock into each other.

[0048] Furthermore, in the mounting structure for the vehicle-mounted component 1, the serpentine portion 6a is formed between the pair of first notches 10 and the pair of fourth notches 14 and the second notches 12 and the pair of third notches 13. On the other hand, it is also possible to omit the pair of fourth notches 14 and form the serpentine portion 6a between the pair of first notches 10 and the second notches 12 and the pair of third notches 13, while ensuring the elastic displacement amount (flexural deformation amount) of the elastic piece 11 necessary to release the locked state between the first locking portion 7 and the second locking portion 9, or to omit the pair of third notches 13 and the pair of fourth notches 14 and form the serpentine portion 6a between the pair of first notches 10 and the second notches 12.

[0049] Furthermore, in the mounting structure of the vehicle-mounted component 1, two symmetrical serpentine portions 6a are provided on both the left and right sides of the first opposing portion 6 described above, but these serpentine portions 6a may also form serpentine portions that are continuous with each other.

[0050] Furthermore, the above-described vehicle-mounted component 1 exemplifies a configuration in which the cover lens 3, which is the second component, is detachably attached to the front side of the case 2, which is the first component. Meanwhile, the present invention can be widely applied to vehicle-mounted components that include a first component and a second component mounted on a vehicle, and in which the second component is detachably attached to the front side of the first component. For example, examples of combinations of the first component and the second component include a bracket and an inner lens, an inner lens and an extension, and a housing and an outer lens.

[0051] Furthermore, the vehicle mounted component 1 is configured to include the above-mentioned sensor unit 5 as a replaceable component, but the replaceable component is not particularly limited, and it is also possible to configure the component to include a light source such as a lamp as a replaceable component.

[0052] Furthermore, the vehicle-mounted components to which the present invention is applied are not limited to those mounted on the front side of the vehicle, such as the front combination lamp described above, but may also be those mounted on the rear side of the vehicle, such as rear combination lamps.
