(overall structure)
The lamps apparatus for vehicle of embodiments of the present invention is described with reference to Fig. 1, Fig. 2 below.
Fig. 1 is the stereogram of the lamps apparatus for vehicle of embodiments of the present invention.As shown in Figure 1, lamps apparatus for vehicle comprises: have the lamp body 1 at the peristome of light fixture front openings; Shell 2 with formed of transparent resin.Shell 2 is configured to from the peristome of front sealed light body 1.Between lamp body 1 and shell 2, be formed with lamp house.
In lamp house, dispose: the distance light lamp unit 3 that can irradiate distance light; With the dipped beam lamp unit 4 that can irradiate dipped beam.Fig. 2 is the vertical cross-section diagram of the lamps apparatus for vehicle of the section that comprises dipped beam lamp unit.As shown in Figure 2, dipped beam lamp unit 4 is projection type lamp units.Dipped beam lamp unit 4 comprises light source 4b, the projecting lens 4a, the speculum 4c etc. that are made up of LED etc.In addition, distance light lamp unit 3 (with reference to Fig. 1) also similarly forms with dipped beam lamp unit 4.In addition, as shown in Figure 1, near the end of the vehicle-width direction in lamp house, be provided with side marker light 5.
As shown in Figure 1, in lamp house, be provided with extension 10 (resin component), from light fixture face side, it makes to cover lamp body 1 the projecting lens 4a of the projecting lens 3a of distance light lamp unit 3, dipped beam lamp unit 4 and state that side marker light 5 is exposed.Extension 10 is the resin components that formed by crystalline resins such as PBT (polybutylene terephthalate (PBT)) or PET (polyethylene terephthalate).
Extension 10 comprises: the pattern plane 10a exposing at light fixture front side; With the non-pattern plane 10b (with reference to a Fig. 2) side, that can not from light fixture front see contrary with this pattern plane 10a.Be formed with smoothly and have minute surface portion 20 and the lower texture portion 21 of gloss of reflecting feel at pattern plane 10a.Texture portion 21 is formed as small male and fomale(M&F), by making light irregular reference present sub-light sensation.Texture portion 21 for example also can be made up of the microspike of stippled shape and small recess, and also can be made up of the small ridge shape thing and the flute profile thing that extend to a direction.In addition, in the present embodiment, the roughly whole region of the pattern plane 10a of extension 10 is formed as minute surface portion 20, is formed with texture portion 21 in a part of pattern plane 10a.In addition, as shown in Figure 2, be provided with the flank 22 extending towards the region of not exposing in light fixture front at non-pattern plane 10b.
As shown in Figure 1 and Figure 2, extension 10 comprises bottom surface sections 11 and rake 12.Bottom surface sections 11 is exposed the projecting lens 4a of dipped beam lamp unit 4 and the projecting lens 3a of distance light lamp unit 3, side marker light 5.Rake 12 surrounds bottom surface sections 11, extends towards front from its outer rim.In addition, be provided with the first cylindrical portion 13 and the second cylindrical portion 14 in bottom surface sections 11, it surrounds respectively the projecting lens 3a of distance light lamp unit 3 and the projecting lens 4a of dipped beam lamp unit 4, and outstanding towards front from bottom surface sections 11.The pattern plane 10a of this first cylindrical portion 13 and the second cylindrical portion 14 is the inclined plane from projecting lens 3a, 4a towards front hole enlargement.
The first 21a of texture portion is formed roughly rectangle at multiple positions of the pattern plane 10a of the second cylindrical portion 14.In the situation that observing from light fixture is positive, above-mentioned multiple the first 21a of texture portion are configured to be radiated entends with respect to the optical axis of dipped beam lamp unit 4.In addition, above-mentioned multiple the first 21a of texture portion is divided into radial by multiple minute surface portion 20.
In addition, the second 21b of texture portion is arranged on a part that is positioned at the region of the below of the first cylindrical portion 13 and the second cylindrical portion 14 in the rake 12 of frame shape.This second texture 21b of portion extends along vehicle-width direction, is formed band shape.The surface roughness of the second 21b of texture portion is different from the surface roughness of the first 21a of texture portion, presents the outward appearance different from the first 21a of texture portion.
Like this, in the lamps apparatus for vehicle of present embodiment, exist by making minute surface portion 20 and the first 21a of texture portion and the second 21b of texture portion mix in the pattern plane 10a of extension 10, improved the aesthetic property of lamps apparatus for vehicle.In addition, in explanation described later, in the situation that not distinguishing the first 21a of texture portion and the second 21b of texture portion especially, referred to as texture portion 21.
(mechanism of production of texture inequality)
In the lamps apparatus for vehicle forming as described above, if produce texture inequality in texture portion 21, damage the aesthetic property of lamps apparatus for vehicle, so be unsafty.Conventionally, texture portion 21 is in the time of extension 10 injection mo(u)lding such as resin such as grade, by the small concavo-convex resin that is needed on that is arranged at mould is formed.Now, if forming desired small be not concavo-convexly transferred when texture portion 21, exist in texture portion 21 and can not produce equably the situation of the irregular reference of light.So, cause light to reflect strongly along specific direction, due to and the texture portion 21 of surrounding normal between there is difference in reflectivity, so can see the candy strip of the deep or light strip differing.This is not thought to the candy strip of seeing is called texture inequality.
Therefore, the inventor finds that texture inequality produces based on following mechanism.Fig. 3 is the schematic diagram representing the extension of comparative example 10 formed in mould situations.
Conventionally, extension 10 resins such as grade are made by mould molding.In the time of mould molding, in order to make to be injected into the aqueous resin solidification in the cavity of mould 30, after resin is cooling, resin produces thermal contraction.Because extension 10 is formed plate-shaped member, so the size of surface direction (left and right directions in figure) is larger than the size of thickness direction.Therefore, on resin, larger convergent force acts on surface direction.
During above-mentioned mould molding, there is resin partly and adhere to strongly the situation (region A in figure) on mould 30 surfaces.If a part of temperature of for example mould 30 is lower, exist resin to be bonded to the situation of the low-temperature region of mould 30.Or if near the resin that flow velocity is higher inlet is suppressed in the surface of mould 30, a part for resin just adheres to the surface of mould 30 strongly.Particularly, larger with the contact area of resin by the small concavo-convex texture transfer section forming 31 that forms texture portion 21, the easy set of resin.Therefore, adhere to the situation of mould 30 at the easy generation resin of texture transfer section 31.
When the cooling contraction of resin in cavity, resin is being pulled to the position that adheres to strongly mould 30 surfaces and is moving.If resin is so mobile, the protuberance 21s in the texture portion 21 that formed contacts and deforms with the protuberance 31a of the texture transfer section 31 of mould 30.Consequently, as shown in Figure 3, the protuberance 21s that is pulled a side forms the state of inclination.So towards inclined multiple protuberance 21s of forming light is reflected along specific direction.Consequently, the region of the protuberance 21s of inclination produces the texture inequality being made up of the candy strip of strip.
Particularly, as mentioned above, due to the texture transfer section 31 that texture portion 21 easily adheres to mould 30, so assembling centered by texture portion 21, moves resin.In this case, the texture inequality of the concentric circles centered by texture portion 21 produces to adhere to the region of mould 30.Because the texture inequality of concentric circles is very obvious, so damaged greatly the outward appearance of extension 10.In addition, if resin entirety because of temperature deviation of mould 30 etc. unequal shrink, protuberance 21s in the different region of each amount of contraction with different angular distortion.In this case, in the different region of each amount of contraction, light reflects to specific direction, produces on the whole the texture inequality of strip.
In addition, because texture inequality is to produce because the small protuberance 21s of texture portion 21 deforms, so even if the movement that produces resin in minute surface portion 20 can not produce texture inequality yet.This is because have the minute surface portion 20 of smooth surface, also can not deform even if resin contacts and move its surface with mould 30.
(effect of flank)
Therefore, the pressure, resin that the inventor keeps resin by the cooling velocity to resin, in mould with certain pressure carries out various changes to conditions of molding such as the injection moulding speed in mould tests, and wants to find to suppress the condition of texture inequality.But, even condition of molding is carried out to various settings, also could not effectively suppress the generation of texture inequality.Therefore, the inventor does not change condition of molding but the structure shrinking on the additional surface that suppresses texture portion 21 of extension 10 is studied.
Fig. 4 has an X-rayed from normal direction the enlarged drawing of observing a part of the pattern plane 10a that is arranged at the second cylindrical portion 14 of the extension 10 shown in Fig. 1.In Fig. 4, the flank 22 that the non-pattern plane 10b dotting at the back side as pattern plane 10a forms.
As shown in Figure 4, be formed with the first 21a of texture portion at the pattern plane 10a of the second cylindrical portion 14 of extension 10, it is rectangle, and is radially and extends with respect to the optical axis of dipped beam lamp unit 4.In addition, in the non-pattern plane 10b of the second cylindrical portion 14, near the outer rim of the region 21t (region, the back side of the first 21a of texture portion) corresponding with this first texture 21a of portion, be provided with flank 22.More specifically, flank 22, along the outer rim of the first 21a of texture portion, is formed linearity.In addition, the region 21t that this flank 22 clips non-pattern plane 10b is relative, is arranged on the position of relative this region 21t symmetry.
Utilize Fig. 5, the manufacture method of extension 10 of first 21a of texture portion with the manufacture method of having applied present embodiment is described.Fig. 5 is that the V-V alignment of Fig. 4 is looked sectional view, the stress that arrow F1, the F2 in figure applies resin while being illustrated in extension 10 moulding.In addition, in Fig. 5, exaggerated texture transfer section 41 small concavo-convex of mould, described greatlyr than in fact.
First, prepare to there is bed die 40 and the mold 50 by the small concavo-convex texture transfer section 41 forming.On mold 50, near the outer rim in the region relative with the texture transfer section 41 of bed die 40, be provided with the flank formation recess 51 that is used to form flank 22.Then, bed die 40 and mold 50 are combined, form cavity C.Material resin is circulated into the inside of formed cavity C, and makes resin cooling curing make extension 10.In addition,, if the inlet (cast gate) of resin is set at flank formation recess 51, in the residual gate vestiges of flank 22 that can not impact the outward appearance of extension 10, institute thinks preferably.
As shown in Figure 5, in the time that resin is cooling, form texture portion 21 by texture transfer section 41, form recess 51 form flank 22 by flank, they are integrally formed as extension 10.At the non-pattern plane 10b of extension 10, the region 21t corresponding with the first 21a of texture portion clipped by pair of ribs 22.Thus, act on the compression stress F1 of resin when cooling, produce reaction force F2 by pair of ribs 22.In addition, pair of ribs 22 is supported securely by the sidewall 53 that is clipped in mold 50 therebetween.Therefore, flank 22 can not be out of shape because of compression stress F1.
Therefore, even if act on as illustrated compressive F1, resin integral surface is shunk, flank 22 also can produce reaction force F2 and hinder the movement of texture portion 21.Thus, compression stress F1 is offset by reaction force F2, and the protuberance of texture portion 21 can not produce the distortion of the movement that is accompanied by resin.Therefore,, according to the extension 10 of the lamps apparatus for vehicle of present embodiment, by flank 22 being set at non-pattern plane 10b, can suppress the generation of texture inequality.In addition, surface shrink refer to towards with the contraction of the perpendicular direction (left and right directions of Fig. 5) of the wall thickness direction of extension 10.
Particularly, according to the extension 10 of the lamps apparatus for vehicle of present embodiment, as shown in Figure 4, pair of ribs 22 arranges symmetrically with respect to the region 21t corresponding with texture portion 21, and region 21t is clipped by pair of ribs 22.Thus, even if a part for texture portion 21 adheres to mould, and compression force makes it to tractive centered by texture portion 21 in resin, and pair of ribs 22 also can produce reaction force from its each side respectively.Thus, can suppress in whole texture portion 21 generation of texture inequality.
In addition,, if form flank 22 at the back side of texture portion 21, there is the situation in the region generating texture inequality corresponding with flank 22 of pattern plane 10a.Therefore, as shown in Figure 4, flank 22 is preferably arranged on and the outer rim of the region 21t corresponding with texture portion 21 separates the outside of predetermined distance and the region corresponding with minute surface portion 20.As mentioned above, even if this is because minute surface portion 20 follows movement cooling and that produce resin, also can not exert an influence to its surface.In addition, the thickness of extension 10 that is preferably formed with the position of texture portion 21 is larger, sets greatlyr from the interval of the outer rim of the region 21t corresponding with texture portion 21.
In addition, the thickness t of flank 22 (with reference to Fig. 5) is preferably 0.2mm above and is to be formed with below the thickness T of extension 10 at the position of texture portion 21.If the thickness of flank 22 is less than 0.2mm, can not bear compression stress F1 by flank 22.In addition, if be greater than the thickness T of extension 10, in the time of mould molding, the position corresponding with flank 22 at pattern plane 10a produces shrink mark, can not form the extension 10 that aesthetic property is good.
In addition, as mentioned above, flank 22 produces the reaction force F2 with respect to compression stress F1 in the time that resin is cooling.Therefore,, if take out extension 10 at the incomplete setting up period of resin from mould 40,50, there is the situation of flank 22 to the curving contrary with the action direction of compression stress F1.But, because flank 22 is arranged on non-pattern plane 10b mono-side of not exposing in light fixture front, so the aesthetic property of lamps apparatus for vehicle can not reduce because of bending flank 22.
In addition, the crystalline resin that is larger 10/1000~20/1000 by molding shrinkage in extension 10 forms, because resin easily shrinks, so easily produce texture inequality.But, as the extension 10 of the lamps apparatus for vehicle of present embodiment, by flank 22 is formed on to non-pattern plane 10b, can effectively suppress the generation of texture inequality.In addition, if use crystalline resin, the viscosity of resin is lower, so extension 10 can form thinlyyer.
In addition, be formed as small male and fomale(M&F) that surface roughness Ra (arithmetic mean surface roughness) is 1~200 μ m in texture portion 21, when produce texture when uneven texture inequality seem dressed to eh nines.Therefore,, in prior art, in the design of the surface roughness of texture portion 21, there is restriction.But, according to the extension 10 of the lamps apparatus for vehicle of present embodiment, be difficult to produce because texture is uneven, so there will not be the restriction in this design.Therefore, can carry out diversified design to extension 10.In addition, if be set as above-mentioned surface roughness, can obtain the small concavo-convex texture portion 21 that transfer printing is good and aesthetic property is good of texture portion 21.The surface roughness Ra of texture portion 21 is preferably 1~100 μ m, and more preferably Ra is 5~50 μ m.
In addition, preferably flank 22 vertically arranges with non-pattern plane 10b, and flank 22 is supported reliably by the sidewall 53 of mold 50.
(the second texture portion)
In addition, the shape of the flank 22 of inhibition texture inequality and formation position are not limited to above-mentioned example.Fig. 6 is the figure same with Fig. 4, and near the second 21b of texture portion that a part for the rake in extension 10 12 is formed, amplification represents.
As shown in Figure 2 and Figure 6, the flank 22 that is arranged near of the second 21b of texture portion is arranged on the dorsal part of minute surface portion 20, and this minute surface portion 20 is positioned at the light fixture front side of the second 21b of texture portion.This flank 22 is formed in the linearity that the direction vertical with the bearing of trend of the second 21b of texture portion extended, and is formed with multiple along the bearing of trend of the second 21b of texture portion.Because the compression stress F1 of the face direction playing a role when extension 10 moulding is born by multiple flanks 22, so also can suppress the generation of texture inequality by such flank 22.
(the first variation)
Fig. 7 is the part enlarged drawing of the extension 10 of the lamps apparatus for vehicle of the first variation of present embodiment.In the present embodiment, be formed with minute surface portion 20 two kind texture portion 21c, the 21ds different with surface roughness at pattern plane 10a.Two kinds of 21c of texture portion, 21d are adjacent to respectively to be formed, and is provided with flank 22 at the back side of its boundary portion 16 (non-pattern plane 10b).Like this, in the case of the outward appearance different 21c of texture portion, 21d are adjacent to form, even produce texture inequality in its boundary portion 16, be also difficult to be found out.Therefore, also can be at the region division flank 22 of the corresponding non-pattern plane 10b of the boundary portion 16 of multiple texture 21c of portion, the 21d different from outward appearance.
In addition, in the example depicted in fig. 7, flank 22 is set to the region corresponding with the 21c of texture portion, 21d of non-pattern plane 10b to surround.Thus, for the compression stress F1 that resin is acted on to resin to tractive centered by the 21c of texture portion, 21d, can reaction force F2 be played a role from whole directions by flank 22.Thus, can effectively suppress the whole texture 21c of portion, 21d and produce texture inequality.
(the second variation)
In the above-described embodiment, the example of enumerating the texture portion 21 of essentially rectangular is illustrated, but the invention is not restricted to this example.Fig. 8 is the part enlarged drawing of the extension 10 of the lamps apparatus for vehicle of the second variation of the present invention.The 21e of texture portion of the extension 10 shown in Fig. 8 is formed substantially elliptical, and flank 22 arranges along the gabarit shape of the 21e of this texture portion.No matter flank 22 by setting like this along the shape of the 21e of texture portion, design the 21e of texture portion of which kind of shape, can both suppress the generation of texture inequality.
In addition, as shown in the figure, flank 22 can be not form in the mode of the gabarit shape of surrounding continuously the region corresponding with the 21e of texture portion yet, but forms in the mode of interrupted encirclement.Even so form flank 22, also can suppress the generation of texture inequality.
(the 3rd variation)
In addition, in the above-described embodiment, be set forth in the example that is provided with texture portion 21 on the same face and be illustrated, but the invention is not restricted to this example.Fig. 9 is the part amplification stereogram of the extension 10 of the lamps apparatus for vehicle of the 3rd variation of present embodiment.
In the extension 10 of the lamps apparatus for vehicle of the 3rd variation shown in Fig. 9, pattern plane 10a is made up of two faces that intersect at bend 17.Form respectively the 21f of texture portion, 21g at two pattern plane 10a that so connect by bend 17, also can flank 22 be set in the non-pattern plane 10b of bend 17 side.This be due to, be difficult to see near the bend 17 of pattern plane 10a from outside, even unobvious in this region generating texture inequality yet.In addition,, in this variation, enumerated using the mountain valley side of bend 17 as pattern plane 10a and the example of flank 22 has been set in mountain peak side, but also can flank 22 be set using the mountain peak side of bend 17 as pattern plane 10a and in mountain valley side.
In addition, in this variation, do not clip the 21f of texture portion, 21g flank is set, and be only provided with flank 22 at an avris of the 21f of texture portion, 21g.Even so form the generation that flank 22 also can suppress texture inequality.In this case, in the time of mould molding, by the compression stress F1 because of cooling generation, the 21f of texture portion, 21g entirety are moved to flank 22, on the whole texture 21f of portion, 21g, the protuberance 21s of the 21f of texture portion, 21g deforms.Therefore, due to protuberance, 21s similarly deforms, so the protuberance 21s after distortion can not be seen as texture inequality.
Above, enumerate embodiment and first~three variation and described the present invention, but the invention is not restricted to above-mentioned example.For example, in above-mentioned example, although adopt flank 22 at the position that suppresses texture inequality, as long as the convergent force generation reaction force can be for mould molding time just can replace flank 22 with projection or protuberance.
In addition, in above-mentioned example, enumerated the surface of resinous speculum is directly illustrated as the example of pattern plane 10a, but the pattern plane 10a that also can form possessing minute surface portion 20 and texture portion 21 implements metal evaporation processing, improves reflecting feel.
In addition, in above-mentioned example, be illustrated as an example of extension 10 example as resin component, but the present invention can be applied to the resin component that is configured in the surrounding of light source and forms texture portion 21 at pattern plane 10a conventionally, that is, and interior lens or outer lens, speculum, lamp body etc.For example, in the lamps apparatus for vehicle of parabola shaped optical system, the luminous intensity distribution of speculum is not being had to contributive region division texture portion.Or, in the situation that the inner surface that makes lamp body exposes in light fixture front, in the pattern plane of lamp body, texture portion is set.In this case, by the region division flank 22 not exposing in light fixture front, can suppress texture portion and produce texture inequality.
In addition, for the uneven flank 22 producing of inhibition texture like this, also can make it have as the function of ribs 22 of rigidity of strengthening extension 10.Or, in the situation that extension 10 being fixed on to lamp body 1 with bolt, also the convex portion of bearing bolt can be arranged on to the non-pattern plane 10b of extension 10, make this convex portion as the uneven restraining outburst of texture portion performance function.In addition also can make in projections such as the pins using in the time that extension 10 is positioned lamp body 1 as the uneven restraining outburst of texture portion performance function.Adopt such structure, without being formed for respectively suppressing texture inequality, for fixing extension 10, for locating the flank 22 of each purposes such as extension 10, can simplify the structure of extension 10.
In addition, the inside in the region corresponding with texture portion 21 in non-pattern plane 10b, also can arrange the reinforcement protuberance of extension 10.This protuberance is used for suppressing texture inequality, sets littlely than the flank 22 of the outer rim setting in the region corresponding with texture portion 21.In the case of by intra-zone corresponding with texture portion 21 in strengthening being arranged on non-pattern plane 10b with protuberance, likely because this reinforcement produces shrink mark with protuberance in texture portion 21, or produce texture inequality.But, if in non-pattern plane 10b the outer rim in the region corresponding with this texture portion 21 arrange than strengthen with protuberance large for suppressing the flank 22 of texture inequality, can make the distortion of resin concentrate near of flank 22.Thus, even because strengthening producing shrink mark or texture inequality with protuberance, also can suppress outward appearance deteriorated of extension 10.In addition, intra-zone that also can be corresponding with texture portion 21 in non-pattern plane 10b arranges fixing with protuberance or location protuberance, replaces reinforcement protuberance.
In addition,, from the outstanding length I (with reference to Fig. 5) of the non-pattern plane 10b of flank 22, as long as can bear the convergent force of resin, its length is not particularly limited.For example, in the case of flank 22 is had the function of strengthening purposes, fixed-purpose, location purposes, can determine its outstanding length I according to their purposes.
In addition,, in the 3rd variation, be illustrated even if enumerated the example of region division flank 22 corresponding with generation texture inequality also inconspicuous bend 17b in non-pattern plane 10b, but the invention is not restricted to this.For example, in the case of being formed with across stage portion same texture portion 21, region division flank 22 that also can be corresponding with stage portion in non-pattern plane 10b.This be due to, unobvious even if stage portion produces texture inequality yet.Like this, even if also can being arranged on, flank 22 produces also non-pattern plane 10b mono-side in inconspicuous region of texture inequality.
In addition, in the above description, enumerated the example that applies the present invention to headlight for automobile and be illustrated, but the present invention also can be applied to Vehicular marker lamp, vehicle interior lamp.
In addition, the lamps apparatus for vehicle of present embodiment can either be applied to 4 vehicles of taking turns, and also can be applied to 3 and take turns or 2 vehicles of taking turns.
In addition, the application is the Japanese patent application (Patent 2011-256958) proposing based on November 25th, 2011, and its content is incorporated into as reference.
