Description

本発明は、車両用前照灯に関する。   The present invention relates to a vehicle headlamp.

従来、自動車用ヘッドランプなどの車両用前照灯として、光源であるバルブからの光をリフレクタで反射させて車両前方へ照射するものが知られている。   2. Description of the Related Art Conventionally, a vehicle headlamp such as an automobile headlamp is known that irradiates light from a bulb, which is a light source, with a reflector and irradiates the vehicle front.

この種の車両用前照灯では、図７に示すように、バルブ１００がリフレクタ１０１のバルブ挿入孔に後方から挿入され、スプリング１０２によって後方からリフレクタ１０１の後面に押圧されることによって、バルブ１００とリフレクタ１０１とが固定されている（例えば、特許文献１参照）。スプリング１０２は、バルブ１００と当接する部分を挟む両端のうちの一方がリフレクタ１０１に取り付けられ、他方である先端がリフレクタ１０１の係止壁１０１ａに係止されることによって、弾性的にバルブ１００を押圧している。   In this type of vehicle headlamp, as shown in FIG. 7, the valve 100 is inserted into the valve insertion hole of the reflector 101 from the rear and is pressed against the rear surface of the reflector 101 from the rear by the spring 102. And the reflector 101 are fixed (see, for example, Patent Document 1). One end of the spring 102 that sandwiches the portion in contact with the valve 100 is attached to the reflector 101, and the other end is locked to the locking wall 101a of the reflector 101, so that the valve 100 is elastically pressed. Pressing.

特開２００３−８６００８号公報JP 2003-86008 A

しかしながら、リフレクタ１０１は一般に樹脂製であるため、図８（ａ），（ｂ）に示すように、スプリング１０２をリフレクタ１０１の係止壁１０１ａに係止するときに、係止壁１０１ａの角部Ｌがスプリング１０２によって削られてしまうことがあった。この削り屑がリフレクタ１０１の前面に回り込んで反射面１０１ｂに付着してしまうと、外観を損なうばかりか、当該削り屑が光路を遮って配光に影響を及ぼす恐れがある。   However, since the reflector 101 is generally made of resin, as shown in FIGS. 8A and 8B, when the spring 102 is locked to the locking wall 101a of the reflector 101, the corner portion of the locking wall 101a is used. L may be scraped off by the spring 102. If the shavings wrap around the front surface of the reflector 101 and adhere to the reflecting surface 101b, the appearance may be impaired, and the shavings may block the optical path and affect the light distribution.

特に、リフレクタ１０１を射出成形によって成形する場合には、反射面１０１ｂ側の成形型Ｍ１と後面側の成形型Ｍ２とを合わせてキャビティーを構成するため、成形型Ｍ１と成形型Ｍ２との合わせ面跡であるパーティングラインＰＬ（図８（ａ）に太線で図示）が係止壁１０１ａの角部Ｌ近傍に形成される。すると、パーティングラインＰＬ上にはバリが生じるため、当該バリを上述の削り屑として削り落としやすくなってしまう。更に、反射面１０１ｂにアルミ蒸着を施す場合には、バリが蒸着膜を被膜されて大きくなるため、削り屑としてバリが削り落とされて反射面１０１ｂに付着してしまうと、上述の不具合が顕著なものとなってしまう。   In particular, when the reflector 101 is molded by injection molding, the mold M1 on the reflective surface 101b side and the mold M2 on the rear surface side are combined to form a cavity, so that the mold M1 and the mold M2 are aligned. A parting line PL (shown by a bold line in FIG. 8A) that is a surface trace is formed in the vicinity of the corner portion L of the locking wall 101a. Then, since burrs are generated on the parting line PL, the burrs are easily scraped off as the above-mentioned shavings. Further, when aluminum deposition is performed on the reflective surface 101b, since the burrs are coated with a vapor deposition film, the burrs are removed as shavings and adhere to the reflective surface 101b. It will become something.

本発明は、上記事情を鑑みてなされたもので、スプリングの係止時にリフレクタが削られることを防止した車両用前照灯の提供を課題とする。   This invention is made | formed in view of the said situation, and makes it a subject to provide the vehicle headlamp which prevented that a reflector was shaved at the time of latching of a spring.

The reflector is an injection-molded product molded using two molds that individually form the front surface and the rear surface of the reflector,
The locking wall is
The front is exposed to the front of the reflector,
An intersecting line between the chamfered surface and the end surface coincides with a parting line corresponding to a mating surface of the two molds.

請求項１に記載の発明によれば、リフレクタが、バルブ挿入孔の近傍に、前面でスプリングの一端と当接して当該スプリングの一端を係止する係止壁を有し、スプリングの一端が、係止壁に係止されるときに係止壁の端面上を通過してから当該係止壁の前面に当接し、この係止壁には、前面と端面との角部に面取りが施されているので、スプリングの一端を係止壁の前面に回り込ませるときに、当該スプリングの一端と係止壁との接触を回避することができる。したがって、スプリングを係止壁に係止するときにリフレクタが削られることを防止できる。   According to the first aspect of the present invention, the reflector has a locking wall in contact with one end of the spring on the front surface and locking one end of the spring in the vicinity of the valve insertion hole, and one end of the spring is When it is locked to the locking wall, it passes over the end surface of the locking wall and then comes into contact with the front surface of the locking wall. The locking wall is chamfered at the corners of the front surface and the end surface. Therefore, when one end of the spring is turned around the front surface of the locking wall, contact between the one end of the spring and the locking wall can be avoided. Therefore, it is possible to prevent the reflector from being scraped when the spring is locked to the locking wall.

請求項２に記載の発明によれば、リフレクタが当該リフレクタの前面と後面とを個別に形成する２つの成形型を用いて成形される射出成形品であり、係止壁の前面がリフレクタの前方へ露出しており、係止壁の面取りがされた面と端面との交線が２つの成形型の合わせ面に対応したパーティングラインと一致しているので、係止壁の前面の角部にパーティングラインが形成されていた従来に比べ、パーティングライン上に生じたバリをスプリングで削り落としにくくすることができるうえに、パーティングラインが相対的に後方へ移動しているためにバリが落ちたとしても前面には回りこみにくく、配光への悪影響等の発生を抑制することができる。   According to the second aspect of the present invention, the reflector is an injection-molded product that is molded using two molds that individually form the front surface and the rear surface of the reflector, and the front surface of the locking wall is the front of the reflector. Since the intersection line between the chamfered surface and the end surface of the locking wall is aligned with the parting line corresponding to the mating surface of the two molds, the corner of the front surface of the locking wall Compared to the conventional case where the parting line is formed, the burr generated on the parting line can be made harder to scrape off with a spring, and the parting line moves relatively backward. Even if the light falls, it is difficult to go around the front surface, and the occurrence of adverse effects on the light distribution can be suppressed.

以下、本発明の実施形態について、図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１は、本実施形態における車両用前照灯１の側断面図であり、図２は、車両用前照灯１の後部の斜視図である。
図１に示すように、車両用前照灯１は、前面が開口したハウジング２と、ハウジング２の前面開口を覆うように配置された透光レンズ３とを備えている。これらハウジング２と透光レンズ３とで形成される灯室内には、樹脂製のリフレクタ４が収容されている。 FIG. 1 is a side sectional view of a vehicular headlamp 1 in the present embodiment, and FIG. 2 is a perspective view of a rear portion of the vehicular headlamp 1.
As shown in FIG. 1, the vehicle headlamp 1 includes a housing 2 whose front surface is open, and a translucent lens 3 arranged so as to cover the front opening of the housing 2. A resin reflector 4 is accommodated in the lamp chamber formed by the housing 2 and the translucent lens 3.

リフレクタ４は、前方へ開口する湾曲板状に形成されており、凹状の前面が後述のバルブ５の光を反射させる反射面４ａを構成している。リフレクタ４の略中央には、前後に貫通したバルブ挿入孔４ｂが形成されており、このバルブ挿入孔４ｂには、光源であるバルブ５が挿入されている。バルブ５は、前後方向の中ほどに取付フランジ５１を有しており、バルブ挿入孔４ｂに後面側から挿入され、フィラメント５２を反射面４ａの略焦点に位置させた状態で、取付フランジ５１を介してリフレクタ４に固定されている。より詳しくは、バルブ挿入孔４ｂは後方へ広がる段付き状に形成されており、この段付き部の後面に取付フランジ５１周縁部の前面を当接させた状態で、バルブ５がリフレクタ４に固定されている。   The reflector 4 is formed in a curved plate shape that opens forward, and the concave front surface constitutes a reflection surface 4a that reflects light from a bulb 5 described later. A bulb insertion hole 4b penetrating in the front-rear direction is formed substantially at the center of the reflector 4, and a bulb 5 as a light source is inserted into the bulb insertion hole 4b. The valve 5 has a mounting flange 51 in the middle in the front-rear direction. The mounting flange 51 is inserted in the valve insertion hole 4b from the rear side, and the filament 52 is positioned at a substantially focal point of the reflecting surface 4a. It is being fixed to reflector 4 via. More specifically, the valve insertion hole 4b is formed in a stepped shape extending rearward, and the valve 5 is fixed to the reflector 4 with the front surface of the peripheral edge of the mounting flange 51 in contact with the rear surface of the stepped portion. Has been.

図２に示すように、リフレクタ４の後面には、バルブ５をリフレクタ４に固定するスプリング６が取り付けられている。スプリング６は、棒状の弾性部材を略コ字状に屈曲させて形成されており、折り返し部分に設けられた取付部６１と、一端に設けられたフック部６２とを有している。このうち、取付部６１は、リフレクタ４後面のバルブ挿入孔４ｂの一方の側部（図２の左側部）にネジ７１及び座金７２によって取り付けられている。一方、フック部６２は、後述するように、リフレクタ４後面のバルブ挿入孔４ｂの他方の側部（図２の右側部）に係止される。また、スプリング６の取付部６１とフック部６２との間，及びスプリング６の他端には、取付フランジ５１の後面を押圧する押圧部６３がそれぞれ形成されている。このように、スプリング６は、取付部６１とフック部６２とでバルブ挿入孔４ｂを左右に跨ぐようにリフレクタ４の後面に取り付けられ、２つの押圧部６３，６３でバルブ５の取付フランジ５１の後面を前方へ押圧することにより、バルブ５をリフレクタ４に固定している。   As shown in FIG. 2, a spring 6 that fixes the valve 5 to the reflector 4 is attached to the rear surface of the reflector 4. The spring 6 is formed by bending a rod-shaped elastic member into a substantially U-shape, and has a mounting portion 61 provided at a folded portion and a hook portion 62 provided at one end. Among these, the attachment portion 61 is attached to one side portion (left side portion in FIG. 2) of the valve insertion hole 4 b on the rear surface of the reflector 4 with a screw 71 and a washer 72. On the other hand, the hook 62 is locked to the other side (the right side in FIG. 2) of the valve insertion hole 4b on the rear surface of the reflector 4, as will be described later. Further, a pressing portion 63 that presses the rear surface of the mounting flange 51 is formed between the mounting portion 61 and the hook portion 62 of the spring 6 and the other end of the spring 6. In this way, the spring 6 is attached to the rear surface of the reflector 4 so as to straddle the valve insertion hole 4b with the attachment portion 61 and the hook portion 62, and the two pressing portions 63 and 63 of the attachment flange 51 of the valve 5 are attached. The valve 5 is fixed to the reflector 4 by pressing the rear surface forward.

図３及び図４に示すように、リフレクタ４の後面であってバルブ挿入孔４ｂの近傍には、スプリング６のフック部６２を係止する係止壁４１が、前後方向に略直交する平面内に立設されている。係止壁４１は、バルブ挿入孔４ｂの周壁と一体的に形成されており、前方の空間がバルブ挿入孔４ｂと連通しているとともに当該空間が上方へ開口している。この係止壁４１には、前面と上端面との角部，及び前面と側端面（バルブ挿入孔４ｂの内周面）との角部に、円弧状の面取りＲがそれぞれ施されている。また、係止壁４１の前面は、リフレクタ４の前方へ露出しているとともに、前方へ突出した凸部４１ａを上半部に有している。   As shown in FIGS. 3 and 4, on the rear surface of the reflector 4 and in the vicinity of the valve insertion hole 4b, there is a locking wall 41 for locking the hook portion 62 of the spring 6 in a plane substantially orthogonal to the front-rear direction. Is erected. The locking wall 41 is formed integrally with the peripheral wall of the valve insertion hole 4b. The front space communicates with the valve insertion hole 4b and the space opens upward. The locking wall 41 is provided with arc-shaped chamfers R at the corners between the front surface and the upper end surface and at the corners between the front surface and the side end surface (inner peripheral surface of the valve insertion hole 4b). Further, the front surface of the locking wall 41 is exposed to the front of the reflector 4 and has a convex portion 41a protruding forward in the upper half.

この係止壁４１に係止されるスプリング６のフック部６２は、より詳細には、押圧部６３から延出してきた先がバルブ挿入孔４ｂの内周側へ上下平面内で折り返されており、その先端が前方へ屈曲されて前後に延在する屈曲部６２ａとなっており、更にその先端がバルブ挿入孔４ｂの外周側へ屈曲された当接部６２ｂとなっている。
このフック部６２を係止壁４１に係止するときには、取付部６１がリフレクタ４に取り付けられた状態において、図５に示すように、フック部６２を前方へ押しつつ下方へ下げることにより、当接部６２ｂが係止壁４１の上端面の上方と凸部４１ａの前方とを通過するとともに、屈曲部６２ａが係止壁４１の側端面の内側を通過して、当接部６２ｂが凸部４１ａの下方まで移動する。こうして、当接部６２ｂが凸部４１ａの下方で係止壁４１の前面と当接することでフック部６２が係止壁４１に係止される。このとき、係止壁４１の角部に面取りＲが施されているので、フック部６２の当接部６２ｂや屈曲部６２ａと係止壁４１との接触を防止することができる。 More specifically, the hook portion 62 of the spring 6 that is locked to the locking wall 41 has its tip extending from the pressing portion 63 folded back in the vertical plane toward the inner peripheral side of the valve insertion hole 4b. The distal end is bent forward and becomes a bent portion 62a extending forward and backward, and the distal end is a contact portion 62b bent toward the outer peripheral side of the valve insertion hole 4b.
When the hook portion 62 is locked to the locking wall 41, as shown in FIG. 5, the hook portion 62 is pushed downward and lowered downward while the mounting portion 61 is attached to the reflector 4. The contact portion 62b passes above the upper end surface of the locking wall 41 and the front of the convex portion 41a, the bent portion 62a passes through the inside of the side end surface of the locking wall 41, and the contact portion 62b is the convex portion. It moves below 41a. Thus, the hook portion 62 is locked to the locking wall 41 by the contact portion 62b contacting the front surface of the locking wall 41 below the convex portion 41a. At this time, since the corner portion of the locking wall 41 is chamfered with R, contact between the locking wall 41 and the contact portion 62b or the bent portion 62a of the hook portion 62 can be prevented.

また、リフレクタ４は、図６（ａ），（ｂ）に示すように、前面の反射面４ａを形成する第１成形型Ｍ１０と、後面を形成する第２成形型Ｍ２０とを用いて成形される射出成形品であり、これら第１成形型Ｍ１０と第２成形型Ｍ２０とを合わせて構成されるキャンバーＣ内に樹脂を充填して成形される。リフレクタ４の成形時における第１成形型Ｍ１０と第２成形型Ｍ２０との合わせ面は、係止壁４１の周辺では、係止壁４１の面取りＲがされた面と上端面及び側端面との交線に沿っている。したがって、第１成形型Ｍ１０と第２成形型Ｍ２０との合わせ面に対応したパーティングラインＰＬは、図４に太線で示すように、係止壁４１の面取りＲがされた面と上端面及び側端面との交線と一致している。   Moreover, the reflector 4 is shape | molded using the 1st shaping | molding die M10 which forms the reflective surface 4a of a front surface, and the 2nd shaping | molding die M20 which forms a rear surface, as shown to Fig.6 (a), (b). This is an injection-molded product, and is molded by filling a resin into a camber C formed by combining the first mold M10 and the second mold M20. When the reflector 4 is molded, the mating surfaces of the first molding die M10 and the second molding die M20 are located around the locking wall 41 between the chamfered surface of the locking wall 41, the upper end surface, and the side end surfaces. Along the line of intersection. Therefore, the parting line PL corresponding to the mating surface of the first molding die M10 and the second molding die M20 has a chamfered surface and an upper end surface of the locking wall 41 as shown by a thick line in FIG. It coincides with the line of intersection with the side end face.

以上の車両用前照灯１によれば、スプリング６のフック部６２を前面で係止する係止壁４１には、前面と上端面との角部，及び前面と側端面との角部に面取りＲが施されているので、スプリング６の当接部６２ｂを係止壁４１の前面に回り込ませるときに、この当接部６２ｂや屈曲部６２ａと係止壁４１との接触を回避することができる。したがって、スプリング６を係止壁４１に係止するときにリフレクタ４が削られることを防止できる。   According to the vehicle headlamp 1 described above, the locking wall 41 that locks the hook portion 62 of the spring 6 at the front surface has corners between the front surface and the upper end surface, and corner portions between the front surface and the side end surface. Since the chamfer R is provided, when the abutting portion 62b of the spring 6 is turned around the front surface of the locking wall 41, contact between the abutting portion 62b or the bent portion 62a and the locking wall 41 is avoided. Can do. Therefore, the reflector 4 can be prevented from being scraped when the spring 6 is locked to the locking wall 41.

また、リフレクタ４が当該リフレクタ４の前面を形成する第１成形型Ｍ１０と後面を形成する第２成形型Ｍ２０とを用いて成形される射出成形品であり、係止壁４１の前面がリフレクタ４の前方へ露出しており、係止壁４１の面取りＲがされた面と上端面及び側端面との交線が第１成形型Ｍ１０と第２成形型Ｍ２０との合わせ面に対応したパーティングラインＰＬと一致しているので、係止壁の前面の角部にパーティングラインが形成されていた従来に比べ、パーティングラインＰＬ上に生じたバリをスプリング６で削り落としにくくすることができるうえに、パーティングラインＰＬが相対的に後方へ移動しているためにバリが落ちたとしても前面には回りこみにくく、配光への悪影響等の発生を抑制することができる。   The reflector 4 is an injection-molded product that is molded by using the first molding die M10 that forms the front surface of the reflector 4 and the second molding die M20 that forms the rear surface, and the front surface of the locking wall 41 is the reflector 4. Parting corresponding to the mating surface of the first molding die M10 and the second molding die M20 is the intersection of the chamfered surface R of the locking wall 41 with the upper end surface and the side end surface. Since it matches the line PL, the burr generated on the parting line PL can be made harder to be scraped off by the spring 6 than in the conventional case where the parting line is formed at the corner of the front surface of the locking wall. In addition, since the parting line PL is moved relatively rearward, even if burrs are dropped, it is difficult for the burr to fall to the front surface, and the occurrence of adverse effects on light distribution can be suppressed.

なお、本発明は上記実施形態に限定して解釈されるべきではなく、適宜変更・改良が可能であることはもちろんである。   It should be noted that the present invention should not be construed as being limited to the above-described embodiment, and of course can be modified or improved as appropriate.

例えば、上記実施形態では、面取りＲは、係止壁４１の前面と上端面との角部，及び前面と側端面との角部にそれぞれ施されることとしたが、スプリング６のフック部６２の係止時において当該フック部６２との接触の恐れのある角部だけに施すこととしてもよい。例えば、フック部６２の係止時にスプリング６の屈曲部６２ａが係止壁４１の側端面よりも大きく内側を通過し、当該屈曲部６２ａと側端面との接触の恐れがない場合には、係止壁４１の前面と上端面との角部だけに面取りＲを施すこととしてもよい。   For example, in the above embodiment, the chamfer R is applied to the corner portion between the front surface and the upper end surface of the locking wall 41 and the corner portion between the front surface and the side end surface, but the hook portion 62 of the spring 6 is used. It is good also as giving only to the corner | angular part with a possibility of a contact with the said hook part 62 at the time of latching. For example, when the hook 62 is locked, the bent portion 62a of the spring 6 passes through the inside larger than the side end surface of the locking wall 41, and there is no fear of contact between the bent portion 62a and the side end surface. It is good also as chamfering R only to the corner | angular part of the front surface of the stop wall 41, and an upper end surface.
