It is provided with side marker light 5 near the end in the vehicle-width direction in lamp house.
As it is shown in figure 1, be provided with extension 10 (resin component) in lamp house, from the point of view of light fixture face side, it makes distance light
Cover under the state that the projecting lens 3a of lamp unit 3, the projecting lens 4a of dipped beam lamp unit 4 and side marker light 5 are exposed
Lamp body 1.Extension 10 is by crystallinity such as PBT (polybutylene terephthalate (PBT)) or PET (polyethylene terephthalate)
The resin component of resin formation.
Extension 10 includes: pattern plane 10a exposed at light fixture front side；And the side contrary with this pattern plane 10a,
Non-pattern plane 10b (with reference to Fig. 2) can not seen from light fixture front.It is formed smooth in pattern plane 10a and there is reflecting feel
Minute surface portion 20 and the relatively low texture portion 21 of gloss.Texture portion 21 is formed as minute asperities face, by making light irregular reference present Asia
Light sensation.Texture portion 21 also such as is able to the microspike by stippled shape and micro-valleys is constituted, and can also be by a side
Constitute to the small ridge shape thing extended and flute profile thing.Additionally, in the present embodiment, pattern plane 10a of extension 10 is substantially
Whole region is formed as minute surface portion 20, and the part in pattern plane 10a is formed with texture portion 21.It addition, as in figure 2 it is shown, non-
Pattern plane 10b is provided with the flank 22 extended towards the region do not exposed in light fixture front.
As shown in Figure 1 and Figure 2, extension 10 includes bottom surface sections 11 and rake 12.Bottom surface sections 11 makes dipped beam lamp unit 4
Projecting lens 4a and the projecting lens 3a of distance light lamp unit 3, side marker light 5 expose.Rake 12 surrounds bottom surface sections 11,
Extend towards front from its outer rim.It addition, be provided with the first cylindrical portion 13 and the second cylindrical portion 14 in bottom surface sections 11, it wraps respectively
Enclose the projecting lens 3a of distance light the lamp unit 3 and projecting lens 4a of dipped beam lamp unit 4, and from bottom surface sections 11 towards front
Prominent.Pattern plane 10a of this first cylindrical portion 13 and the second cylindrical portion 14 is from projecting lens 3a, 4a expanding inclining towards front
Inclined-plane.
First texture portion 21a is formed generally rectangular at multiple positions of pattern plane 10a of the second cylindrical portion 14.?
In the case of light fixture front is observed, above-mentioned multiple first texture portion 21a are configured to the optical axis relative to dipped beam lamp unit 4
Extend radially.It addition, above-mentioned multiple first texture portion 21a is divided into radial by multiple minute surface portions 20.
It addition, the second texture portion 21b is arranged in the rake 12 of frame-shaped is positioned at the first cylindrical portion 13 and the second cylinder
The part in the region of the lower section in portion 14.This second texture portion 21b extends along vehicle-width direction, is formed banding.Second
The surface roughness of texture portion 21b is different from the surface roughness of the first texture portion 21a, presents different from the first texture portion 21a
Outward appearance.
So, in the lamps apparatus for vehicle of present embodiment, by making minute surface portion in pattern plane 10a of extension 10
20 and first texture portion 21a and the second texture portion 21b be mixed, improve the aesthetic property of lamps apparatus for vehicle.Additionally,
In explanation described later, in the case of distinguishing the first texture portion 21a and the second texture portion 21b the most especially, referred to as texture portion
21。
(mechanism of production that texture is uneven)
In the lamps apparatus for vehicle constituted as described above, if produce texture in texture portion 21 uneven, then damage car
With the aesthetic property of light fixture, so being unsafty.Generally, texture portion 21 is to be molded at extension 10 resin such as grade
During molding, formed by the minute asperities being arranged at mould is needed on resin.Now, if forming texture portion 21
Time desired minute asperities be not transferred, then there is the situation of the irregular reference that will not produce light in texture portion 21 equably.
Then, light is caused to reflect strongly along specific direction, owing to there is difference in reflectivity between the texture portion 21 of surrounding normal
Reason, it is possible to see the candy strip of the deep or light strip differed.This candy strip not wanted to see that is referred to as texture not
All.
Therefore, the inventors discovered that texture is not all based on following mechanism and produces.Fig. 3 is to represent prolonging comparative example
The schematic diagram of the formed in mould situation in exhibition portion 10.
Generally, extension 10 resin such as grade is made by mould molding.When mould molding, in order to make to be injected into mould
After fluid resin in the cavity of tool 30 solidifies and cooled down by resin, resin produces thermal contraction.Owing to extension 10 is formed
Plate-shaped member, so the size of surface direction (left and right directions in figure) is bigger than the size of thickness direction.Therefore, on resin relatively
Big contractility acts on surface direction.
During above-mentioned mould molding, there is resin portion ground and adhere to the situation (figure on mould 30 surface strongly
Middle region A).If a part of temperature of such as mould 30 is relatively low, then there are the feelings that resin is bonded to the low-temperature region of mould 30
Condition.Or, if the resin that flow velocity is higher near inlet is suppressed in the surface of mould 30, then a part for resin is the most relatively
Adhere to by force the surface of mould 30.Particularly, the texture transfer section 31 being made up of the minute asperities forming texture portion 21 and tree
The contact area of fat is relatively big, the easy set of resin.Therefore, easily produce resin in texture transfer section 31 and adhere to the feelings of mould 30
Condition.
During resin cooling meat in cavity, resin is pulled to the portion's displacement adhering to mould 30 surface strongly
Dynamic.If resin is the most mobile, then the protuberance of the texture transfer section 31 of the protuberance 21s in the texture portion 21 formed and mould 30
31a contacts and deforms.As a result of which it is, as it is shown on figure 3, the protuberance 21s being pulled side forms the state of inclination.So to
The multiple protuberance 21s the formation of inclined ground make light reflect along specific direction.As a result of which it is, the protuberance 21s tilted
To produce the texture that is made up of the candy strip of strip uneven in region.
Particularly, be as noted previously, as texture portion 21 and be easily adhered the texture transfer section 31 in mould 30, thus resin with
Assemble mobile centered by texture portion 21.In this case, centered by the region that texture portion 21 produces to adhere to mould 30
The texture of concentric circles uneven.Owing to the texture inequality of concentric circles is the most obvious, so compromising extension 10 greatly
Outward appearance.If unequally shunk additionally, resin is overall because of the temperature deviation of mould 30 etc., then protuberance 21s is in each contraction
Measure in different regions and deform at different angles.In this case, in the region that each amount of contraction is different, light is to specific
Direction is reflected, and the texture producing strip on the whole is uneven.
Additionally, due to texture inequality is to produce because the small protuberance 21s in texture portion 21 deforms, so at mirror
Even if face 20 produces the movement of resin, texture also will not be produced uneven.This is because in the minute surface portion 20 with smooth surface,
Even if resin contacts and moves its surface with mould 30 and also will not deform.
(effect of flank)
Therefore, the present inventor by the rate of cooling to resin, in mould with certain pressure keep the pressure of resin, tree
The conditions of molding such as fat injection moulding speed in mould carry out various change and test, it is desirable to find the bar that suppression texture is uneven
Part.But, even if condition of molding to be carried out various setting, also could not effectively suppress the generation that texture is uneven.Therefore, the present invention
People does not changes condition of molding but is ground the structure of the surface shrinkage in extension 10 additional suppression texture portion 21
Study carefully.
Fig. 4 is observe the extension 10 shown in Fig. 1 from the normal direction pattern being arranged at the second cylindrical portion 14 with having an X-rayed
The enlarged drawing of a part of face 10a.In the diagram, non-pattern plane 10b institute at the back side as pattern plane 10a is represented by dashed line
The flank 22 formed.
As shown in Figure 4, pattern plane 10a in the second cylindrical portion 14 of extension 10 is formed with the first texture portion 21a, its in
Rectangle, radially extends relative to the optical axis of dipped beam lamp unit 4.It addition, in the non-pattern plane of the second cylindrical portion 14
Arrange near the outer rim of region 21t (rear surface regions of the first texture portion 21a) corresponding with this first texture portion 21a in 10b
There is flank 22.More specifically, flank 22, along the outer rim of the first texture portion 21a, is formed linearity.It addition, this flank
22 clip the region 21t of non-pattern plane 10b relatively, are arranged on relatively symmetrical for this region 21t position.
Utilize Fig. 5, the system to the extension 10 of the first texture portion 21a with the manufacture method applying present embodiment
The method of making illustrates.Fig. 5 is that the V-V alignment of Fig. 4 regards sectional view, and arrow F1, the F2 in figure represents when extension 10 molding
The stress that resin is applied.Additionally, in Figure 5, exaggerate the minute asperities of the texture transfer section 41 of mould, describe than reality
Upper big.
First, lower mold 40 and the mold 50 with the texture transfer section 41 being made up of minute asperities is prepared.In upper mold
On tool 50, near the outer rim in the region relative with the texture transfer section 41 of lower mold 40, it is provided with the rib for forming flank 22
Portion forms recess 51.Then, lower mold 40 and mold 50 are combined, form cavity C.Material resin is circulated into institute's shape
The inside of the cavity C become, and make resin cooling and solidifying make extension 10.If arranged additionally, form recess 51 at flank
The inlet (cast gate) of resin, then will not remain gate vestiges to the flank 22 that the outward appearance of extension 10 impacts, so
For preferably.
As it is shown in figure 5, when resin cools down, form texture portion 21 by texture transfer section 41, form recess by flank
51 form flank 22, and they are integrally formed as extension 10.In non-pattern plane 10b of extension 10, with the first texture portion 21a
Corresponding region 21t is clipped by pair of ribs 22.Compression stress F1 of resin is acted on, by a pair rib during accordingly, for cooling
Portion 22 produces counteracting force F2.Additionally, pair of ribs 22 is supported securely by the sidewall 53 of mold 50 sandwiched therebetween.Cause
This, flank 22 will not deform because of compression stress F1.
Therefore, even if effect compressive F1 makes resin integral surface shrink as illustrated, flank 22 also can produce
Counteracting force F2 hinders the movement in texture portion 21.Thus, compression stress F1 is reacted power F2 and offsets, and the protuberance in texture portion 21 is not
The deformation of the movement along with resin can be produced.Therefore, according to the extension 10 of the lamps apparatus for vehicle of present embodiment, by
Non-pattern plane 10b arranges flank 22, it is possible to the generation that suppression texture is uneven.Additionally, surface shrinkage refer to towards with extension 10
The contraction in perpendicular direction (left and right directions of Fig. 5), wall thickness direction.
Particularly, according to the extension 10 of the lamps apparatus for vehicle of present embodiment, as shown in Figure 4, pair of ribs 22 is relative
Being symmetrically arranged in the region 21t corresponding with texture portion 21, region 21t is clipped by pair of ribs 22.Thus, though texture portion
The part of 21 adheres to mould, and compression force makes it to tractive, pair of ribs centered by texture portion 21 in resin
22 also are able to produce respectively counteracting force from its each side.Thereby, it is possible to suppress the generation of texture inequality in whole texture portion 21.
If additionally, form flank 22 at the back side in texture portion 21, then exist in pattern plane 10a is corresponding with flank 22
Region in produce the situation that texture is uneven.Therefore, as shown in Figure 4, flank 22 is preferably provided at and corresponding with texture portion 21
The outer rim of region 21t separate the outside of predetermined distance and the region corresponding with minute surface portion 20.As it has been described above, this is because mirror
Even if face 20 produces the movement of resin with cooling, also its surface will not be produced impact.Additionally, it is preferred that be formed with texture
The thickness of the extension 10 at the position in portion 21 is the biggest, from and the interval of outer rim of the corresponding region 21t in texture portion 21 be set to
The biggest.
It addition, the thickness t (with reference to Fig. 5) of flank 22 is preferably more than 0.2mm and is the position being formed with texture portion 21
Below the thickness T of extension 10.If the thickness of flank 22 is less than 0.2mm, then can not be born compression stress F1 by flank 22.Separately
Outward, if greater than the thickness T of extension 10, then when mould molding at the position product corresponding with flank 22 of pattern plane 10a
Raw shrink mark, it is impossible to form the extension 10 that aesthetic property is good.
Additionally, as it has been described above, flank 22 produces the counteracting force F2 relative to compression stress F1 when resin cools down.Therefore,
If taking out extension 10 from mould 40,50 during resin is not fully cured, then there is flank 22 to the work with compression stress F1
Situation with curving in opposite direction.But, owing to flank 22 is arranged on non-pattern plane 10b do not exposed in light fixture front
Side, so the aesthetic property of lamps apparatus for vehicle will not reduce because of the flank 22 of bending.
It addition, extension 10 by molding shrinkage be bigger 10/1000～20/1000 crystalline resin formed
In the case of, because resin easily shrinks, so it is uneven easily to produce texture.But, such as the lamps apparatus for vehicle of present embodiment
Extension 10 is such, by flank 22 is formed at non-pattern plane 10b, it is possible to the generation that suppression texture is uneven effectively.It addition,
If use crystalline resin, then the viscosity of resin is relatively low, so extension 10 can be formed relatively thin.
It addition, being formed as surface roughness Ra (arithmetic mean surface roughness) in texture portion 21 is the small of 1～200 μm
In the case of male and fomale(M&F), when producing texture inequality, texture inequality seems dressed to eh nines.Therefore, in prior art, at texture
Restriction is occurred in that in the design of the surface roughness in portion 21.But, according to the extension 10 of the lamps apparatus for vehicle of present embodiment,
Owing to texture inequality is difficult to produce, so the restriction not had in this design.Therefore, it is possible to extension 10 is carried out multiple
Various design.It addition, if set to above-mentioned surface roughness, then the transferability of the minute asperities in texture portion 21 can be obtained
Good and that aesthetic property is good texture portion 21.The surface roughness Ra in texture portion 21 is preferably 1～100 μm, more preferably Ra be 5～
50μm。
Additionally, it is preferred that flank 22 is vertically arranged with non-pattern plane 10b so that flank 22 can by the sidewall 53 of mold 50
By ground supporting.
(the second texture portion)
Additionally, the shape of the flank 22 of suppression texture inequality and forming position are not limited to above-mentioned example.Fig. 6 is same with Fig. 4
The figure of sample, near a second texture portion 21b part for the rake 12 in extension 10 formed, amplification represents.
As shown in Figure 2 and Figure 6, the flank 22 of the vicinity being arranged at the second texture portion 21b is arranged on the dorsal part in minute surface portion 20,
This minute surface portion 20 is positioned at the light fixture front side of the second texture portion 21b.This flank 22 be formed with the prolonging of the second texture portion 21b
Stretch the linearity that vertical direction, direction extends, and be formed multiple along the bearing of trend of the second texture portion 21b.Due to
Compression stress F1 in the direction, face played a role during extension 10 molding is born by multiple flanks 22, so by such flank 22
It also is able to the generation suppressing texture uneven.
(the first variation)
Fig. 7 is the magnified partial view of the extension 10 of the lamps apparatus for vehicle of the first variation of present embodiment.In this reality
Execute in mode, be formed with, in pattern plane 10a, two kinds of texture portions 21c, 21d that minute surface portion 20 is different with surface roughness.Two kinds of stricture of vaginas
Reason portion 21c, 21d are adjacent to be formed respectively, and the back side (non-pattern plane 10b) of its boundary portion 16 is provided with flank 22.So,
In the case of texture portion 21c, 21d that outward appearance is different is adjacent to be formed, even if it is uneven, also to produce texture in its boundary portion 16
It is difficult to be seen.Accordingly it is also possible at the corresponding non-pattern of the boundary portion 16 of different from outward appearance multiple texture portion 21c, 21d
The region of face 10b arranges flank 22.
It addition, in the example depicted in fig. 7, flank 22 be arranged to by non-pattern plane 10b with texture portion 21c, 21d phase
Corresponding region surrounds.The compression stress of resin is acted on to tractive centered by texture portion 21c, 21d accordingly, for by resin
F1, it is possible to make counteracting force F2 play a role from whole directions by flank 22.Thereby, it is possible to effectively suppress whole texture portion
It is uneven that 21c, 21d produce texture.
(the second variation)
In the above-described embodiment, the example enumerating substantially rectangular texture portion 21 is illustrated, but the present invention is not
It is limited to this example.Fig. 8 is the magnified partial view of the extension 10 of the lamps apparatus for vehicle of second variation of the present invention.Shown in Fig. 8
The texture portion 21e of extension 10 is formed substantially elliptical, and flank 22 is arranged along the outline shape of this texture portion 21e.Logical
Cross the flank 22 being arranged such the shape along texture portion 21e, no matter design the texture portion 21e of which kind of shape, can suppress
The generation that texture is uneven.
It addition, as it can be seen, flank 22 can not also be to surround the outer profile in the region corresponding with texture portion 21e continuously
The mode of shape is formed, but is formed in the way of interrupted encirclement.Even so flank 22 is formed, it is also possible to suppression texture is uneven
Generation.
(the 3rd variation)
It addition, in the above-described embodiment, it is set forth on the same face and is provided with the example in texture portion 21 and is illustrated, but
It is to the invention is not restricted to this example.Fig. 9 is that the part of the extension 10 of the lamps apparatus for vehicle of the 3rd variation of present embodiment is put
Big axonometric chart.
In the extension 10 of the lamps apparatus for vehicle of the 3rd variation shown in Fig. 9, pattern plane 10a is handed over by bending section 17
Two faces of fork are constituted.The feelings of texture portion 21f, 21g are formed respectively in two pattern plane 10a connected thus by bending section 17
Under condition, it is also possible in the non-pattern plane 10b side of bending section 17, flank 22 is set.This is because, be difficult to externally visibly pattern
Near the bending section 17 of face 10a, even if producing texture inequality the most in this region.Additionally, in this variation, enumerate
Using the side, mountain valley of bending section 17 as pattern plane 10a the example that arranges flank 22 in side, mountain peak, but can also be with bending
The side, mountain peak in portion 17 arranges flank 22 as pattern plane 10a and in side, mountain valley.
It addition, in this variation, do not clip texture portion 21f, 21g to arrange flank, and only at texture portion 21f, 21g
An avris be provided with flank 22.Even so the generation that flank 22 also is able to suppress texture uneven is formed.In this case,
When mould molding, by compression stress F1 produced because of cooling, texture portion 21f, 21g entirety is made to move to flank 22, whole
The protuberance 21s of 21f, 21g upper texture portion of texture portion 21f, 21g deforms.Accordingly, because protuberance 21s similarly deforms,
So the protuberance 21s after Bian Xing will not be seen as texture inequality.
Above, list embodiment and first～the 3rd variation describe the present invention, but the present invention is not
It is limited to above-mentioned example.The most in the examples described above, although have employed flank 22 at the position that suppression texture is uneven, but as long as energy
Enough for contractility generation counteracting force during mould molding, it is possible to use projection or protuberance to replace flank 22.
It addition, in the examples described above, the example that the surface of resinous reflecting mirror is directly used as pattern plane 10a is listed
It is illustrated, but pattern plane 10a that can also be formed possessing minute surface portion 20 and texture portion 21 is implemented at metal evaporation
Reason, improves reflecting feel.
It addition, be illustrated as a example by extension 10 as resin component in the examples described above, but the present invention is usual
Can be applied to be arranged in the surrounding of light source and form the resin component in texture portion 21 in pattern plane 10a, i.e. interior lens or pass through inside
Mirror, reflecting mirror, lamp body etc..Such as, in the lamps apparatus for vehicle of parabola shaped optical system, the luminous intensity distribution of reflecting mirror do not had tribute
The region offered arranges texture portion.Or, make the inner surface of lamp body in the case of light fixture front is exposed, in the pattern plane of lamp body
Texture portion is set.In this case, by arranging flank 22 in the region in light fixture front not exposing, it is possible to suppression texture portion
Generation texture is uneven.
It addition, for the flank 22 that so suppression texture inequality produces, it is also possible to make it have as strengthening extension 10
The function of ribs 22 of rigidity.Or, in the case of extension 10 being fixed on lamp body 1 with bolt, it is also possible to will hold
It is arranged on non-pattern plane 10b of extension 10 by the convex portion of bolt, makes this convex portion send out as texture inequality restraining outburst portion
Wave function.In addition it is also possible to make the projections such as the pin used when extension 10 is positioned lamp body 1 dash forward as the suppression of texture inequality
Go out portion's function.Use such structure, it is not necessary to formed respectively and be used for suppressing texture inequality, being used for fixing extension 10, using
Flank 22 in location extension 10 each purposes such as grade, it is possible to simplify the structure of extension 10.
Additionally, the inside in region corresponding with texture portion 21 in non-pattern plane 10b, it is also possible to extension 10 is set
Reinforcement protuberance.This protuberance is used for suppressing texture uneven, is set to than the outer rim in the region corresponding with texture portion 21
The flank 22 arranged is little.Reinforcement protuberance is being arranged on intra-zone corresponding with texture portion 21 in non-pattern plane 10b
In the case of, it is possible to produce shrink mark in texture portion 21 because of this reinforcement protuberance, or it is uneven to produce texture.But, as
The outer rim in the region the most corresponding with this texture portion 21 in non-pattern plane 10b of fruit arranges bigger than reinforcement protuberance for suppressing
The flank 22 that texture is uneven, then can make the deformation of resin concentrate on the vicinity of flank 22.Thus, even if because of reinforcement protuberance
And produce shrink mark or texture inequality, it is also possible to the deterioration of the outward appearance of suppression extension 10.In addition it is also possible in non-pattern plane 10b
In the intra-zone corresponding with texture portion 21 fixing protuberance or location protuberance are set, replace reinforcement with prominent
Portion.
Additionally, from prominent length I (with reference to Fig. 5) of non-pattern plane 10b of flank 22, as long as the contraction of resin can be born
Power, then its length is not particularly limited.Such as make flank 22 have to strengthen the function of purposes, fixed-purpose, location purposes
In the case of, it is possible to determine its prominent length I according to their purposes.
Additionally, in the 3rd variation, even if listing in non-pattern plane 10b the most inconspicuous with generation texture inequality
Region corresponding for bending section 17b arranges the example of flank 22 and is illustrated, but the invention is not restricted to this.Such as across
In the case of stage portion is formed with same texture portion 21, it is also possible to region corresponding with stage portion in non-pattern plane 10b
Flank 22 is set.Even if this is because, stage portion produces texture inequality the most unobtrusively.So, flank 22 can also be arranged shortly
Make the non-pattern plane 10b side in generation texture the most inconspicuous uneven region.
It addition, in the above description, list and apply the present invention to the example of headlight for automobile and be illustrated, but
It is that the present invention can also be applied to Vehicular marker lamp, vehicle interior lamp.
