The specific embodiment
The present invention is described in detail according to illustrated embodiment below.Fig. 1 and Fig. 2 schematically show the state of making uniform of cowl lamp lens 1 and car body 10, and Fig. 1 is a front view, and Fig. 2 is the partial sectional view of Fig. 1.Particularly, the structure that relates to a kind of like this cowl lamp lens: it forms as the structure that covers a plurality of light fixtures, on car body, be provided with and be equipped with the lamp installation portion that is set as bigger peristome etc., described thus lamp installation portion becomes the concavo-convex curved surface that has along the complexity of car body design, described cowl lamp lens also must have complicated shape for consistent with described curved surface, thereby forms relatively difficulty.
Here, in Fig. 1, represent with following example: between the lamp installation portion 11 that described cowl lamp lens 1 and car body 10 for example are provided with as peristome, be provided with the gap S that is set at certain intervals, the adjustment in described gap is to be undertaken by the installation site of adjusting described cowl lamp lens 1 with respect to car body 10, yet the actual conditions that exist in reality are: because the maximization of described cowl lamp lens 1, contraction during because of moulding etc. makes the shape of peripheral edge portion produce difference with respect to the shape that is arranged on the installing hole portion on the car body 10, thereby causes making uniform very difficulty.
In addition, as shown in Figure 2, near the peripheral edge portion 1b of described cowl lamp lens 1, the housing that is used to install housing 4 is installed shank 2 and is formed from the 1c of back side portion side-prominent, therefore, thicker near the lamp lens surface element 1a corresponding to this part than other parts, become the condition that easy generation is shunk.
So, because of above-mentioned housing shank 2 is installed and on described lamp lens surface element 1a, is produced contraction, so since this contraction and easily and described car body 10 between to produce ladder poor, in addition, because it is dazed and confused that described contraction also makes from the reverberation generation of described lamp lens surface element 1a, comprehensive above reason is felt near the peripheral edge portion 1b of cowl lamp lens 1 beholder, especially it is very insufficient in appearance to make uniform, and the result has caused damaging aesthetic feeling, the product texture of vehicle integral body.
The present invention proposes in view of above-mentioned present situation, near the peripheral edge portion 1b of described cowl lamp lens 1, roughly with the 1c of portion side overleaf housing is set and the position of shank 2 is installed is provided with slot part 3 accordingly.At this moment, described slot part 3 forms apart from the distance of described peripheral edge portion 1b equal substantially.
Like this, described slot part 3 makes the part that is provided with this slot part 3, and the surface area that exposes at the lamp lens surface element 1a of described cowl lamp lens 1 increases, thus can promote moulding the time by the cooling of mould, and can improve degree of being adjacent to mould.Therefore, slot part 3 can reduce the influence that described housing is installed shank 2, prevents to produce contraction in this part.In addition, even producing under the situation of shrinking,, can play the visually unconspicuous effect of being created in of contraction that makes by forming and shrinking the slot part 3 that is similarly concavity.
In addition, by slot part 3 is set near peripheral edge portion 1b, the profile end at peripheral edge portion 1b in the time of can also preventing cowl lamp lens 1 moulding produces contraction like this, and described cowl lamp lens 1 can obtain correct appearance and size, shape.Therefore, easily with the counterpart of the cowl lamp lens 1 installation usefulness that is arranged at car body 10 consistent in shape, the management of making uniform easily.
In addition, shape about described cowl lamp lens 1, can select different shape according to the design of automobile etc., therefore, the housing of the shape of described lamp lens surface element 1a, the shape of peripheral edge portion 1b and the 1c of back side portion is installed position etc. is set can carries out various changes of shank 2.
Therefore, in the present invention, cross sectional shape when the width of the described slot part 3 that is provided with, the degree of depth, formation groove shape etc., as long as the design of setting for by implementing on this cowl lamp lens 1 can obtain effective effect, in addition, the number that is provided with also is not limited to one, though omitted diagram, parallel a plurality of grooves for example can be set.
Here, install on the shank 2 at described housing, usually mainly implement annular knurl in inner face side and add the 2a of the Ministry of worker, produce inharmonious sense to prevent to see the internal structure of light fixture from the outside, vehicles or pedestrians that perhaps prevent to make the opposite from the unnecessary direction of the direct light directive of light source etc. feel dazzling.
As mentioned above, because installing shank 2, described housing extends setting from described lamp lens surface element 1a along the approximate right angle direction, therefore only this housing part that shank 2 is installed becomes thicker and produces and shrink, and described in the present invention slot part 3 is provided with in order to prevent the problems referred to above.Therefore, described slot part 3 is installed the position of shank 2 with respect to described housing is set, and is provided with as the surface of cowl lamp lens 1 and the relation between the back side, thereby can obtains to realize to prevent the effect of the purpose of shrinking effectively.
In addition, when such formation, because the cross sectional shape of described slot part 3 is the concave surface of semicircle shape etc., therefore when in described cowl lamp lens 1, seeing from this slot part 3, the visual angle becomes open in cowl lamp lens 1, and what see from described slot part 3 also is that described annular knurl adds the 2a of the Ministry of worker.In addition, described cowl lamp lens 1 is formed by transparent resins such as Merlon, thereby has high index of refraction, even the face in the outside of shank 2 for example is installed at housing, the inner face reflection can take place also.
Therefore, by slot part 3 is set, the reflection image that cowl lamp lens 1 makes the annular knurl that reflexes to peripheral edge portion 1b add the 2a of the Ministry of worker also can be seen near described peripheral edge portion 1b, make the observer can feel complicated curved shape or depth sense etc., even under the situation that can not fully guarantee the precision of making uniform between each straight line, can not make the observer feel strong inharmonious sense yet.
In addition, cowl lamp lens 1 also overleaf the housing of the 1c of portion near the ladder difference portions 5 that are provided with the shank 2 as shown in Figure 2 are installed.By this ladder difference portion 5, be difficult to the direct transmission back side 1c of portion from the light in cowl lamp lens 1 front.Like this, by this species stage difference portion 5 is set, cowl lamp lens 1 can make the seal member 6 that is encapsulated in housing 4 inside that are inserted with housing installation shank 2 not obvious when inwardly seeing from the front.And this ladder difference portion 5 can make in the bad part of the evaporation of generations such as the end of housing 4 4a or coating state not obvious when the front is seen.
As mentioned above, according to the present invention, first, by be provided with on the cowl lamp lens 1 housing install shank 2 near be the lamp lens surface element 1a side of peripheral edge portion 1b, the slot part 3 that the cross section is roughly semicircle shape is set, can avoid produce shrinking, and can make the shape of periphery 1d of cowl lamp lens 1 correct, thereby make and become easy with making uniform of car body 10 in lamp lens surface element 1a side.
In addition, second, by forming described slot part 3, even there is slight alignment error, the observer also is difficult to visually detect the deviation of projecting height (り looses), thereby can significantly simplify the operation of making uniform, particularly simplify the operation of the difficulties such as adjustment of ladder difference direction, when significantly improving operating efficiency, improve aesthetics.
