Description

  The present invention relates to a side turn lamp device mounted on a door mirror of a vehicle.

  There is a vehicle (for example, an automobile) in which a side turn lamp device is mounted on a door mirror (see, for example, Patent Document 1). When a side turn lamp device is mounted on a door mirror, the luminous intensity, emission angle, etc. of the lamp are stipulated by laws and regulations. That is, as shown in FIG. 6, a straight line L1 inclined outward by a predetermined angle θ1 (5 degrees in the law) with respect to the straight line L along the longitudinal direction of the vehicle, and a predetermined angle θ2 (in accordance with the law) from the straight line L1. In the region surrounded by the straight line L2 inclined by 55 degrees (outside oblique rear region V), it is determined that light should be emitted at a predetermined luminous intensity (0.6 cd or more according to the law).

  In the conventional side turn lamp device 200 ′ of the door mirror 100 ′, a light source is attached to the inside of the door mirror 100 ′, a portion of the housing cover 51 that is irradiated with light from the light source is cut out, and a separate cover body 52 is provided at the opening. Is placed. The cover body 52 is made of a transparent member for efficiently transmitting light from the light source. For this reason, the light source is visually recognized from the outside, and the appearance is not good. Further, the colors and textures of the housing cover 51 and the cover body 52 are greatly different, and it has been found at a glance that the side turn lamp device 200 'is mounted on the door mirror 100', which lacks novelty. In FIG. 6, reference numeral 53 denotes a mirror.

In addition, in order to ensure the luminous intensity of the emitted light, it is necessary to arrange a large number of light sources or use a high-power light source, which may increase the cost and expend the battery.

  In view of the above problems, an object of the present invention is to provide a side-turn lamp device for a door mirror that emits light in an unprecedented form and that can suppress high power of a light source.

Means and effects for solving the problems

The present invention for solving the above problems is as follows.
A side turn lamp device mounted on a door mirror of a vehicle,
A light source built in the door mirror to irradiate light,
A part of the door mirror attached to the vehicle is provided in a portion from the side surface corresponding to the side of the vehicle to the front of the vehicle, and transmits a part of the light emitted from the light source to the outside of the door mirror. A translucent part that has been subjected to a half mirror process for reflecting the back of the vehicle,
Of the light reflected by the half mirror processing surface, disposed at a predetermined angle with respect to the front-rear direction of the vehicle, it is disposed inside the door mirror so as to face the half mirror processing surface of the translucent part. A reflector for re-reflecting the light traveling toward the region other than the outer oblique rear region and guiding it to the half mirror processing surface,
The light irradiated from the light source and reflected by the half mirror processing surface toward a region other than the diagonally rear outer region of the vehicle is reciprocated at least once between the reflector and the half mirror processing surface of the translucent portion. It is characterized in that it is guided to the outer oblique rear region while being reflected.

  The present invention is configured as described above, and the light emitted from the light source is reflected back and forth one or more times between the reflector and the half mirror processing surface of the translucent part, and is guided to the obliquely rearward outer region of the vehicle. It is burned. Here, since the translucent part is the half mirror processing surface, the translucent part can be formed directly on the case body. In other words, since it is possible to prevent a third party from recognizing that the side mirror is provided on the door mirror, it is possible to improve the aesthetics of the door mirror. Further, since the light emitted from the light source is guided while being repeatedly reflected, attenuation of the amount of light when reflected by the half mirror processing surface can be minimized, and it is not necessary to increase the power of the light source.

  The translucent part is preferably provided integrally with the case body of the door mirror so that the boundary line of the translucent part is difficult to visually recognize when the light source is turned off.

  As a result, when the side turn lamp device is activated, a third party feels that a part of the case body of the door mirror suddenly emits light, so that it is possible to emit light in an unprecedented and novel form.

And the opening is provided in the part from the outer side surface part of the vehicle in the case body of the door mirror in a state attached to the vehicle to the front,
The translucent part may be provided in a cover body arranged in the opening.

  In this case, high power of the light source can be suppressed, and an effect that the light source can be attached to an existing door mirror is exhibited.

  The light source may be disposed between the half mirror processing surface of the translucent part and the reflector so as to irradiate both the half mirror processing surface and the reflector.

  By arranging the light source in this way, the light irradiated from the light source that is not directed to the half mirror processing surface can be reflected by the reflector and can be directed to the half mirror processing surface. Thereby, attenuation of light quantity can be suppressed most effectively.

  The half mirror processing surface is preferably formed on the inner peripheral surface of the light transmitting portion. This half-mirror treated surface can be formed by setting a film that has been subjected to a half-mirror treatment, for example, in a mold and simultaneously molding with a case body (film insert molding), or by pre-molding a film that has been preformed by vacuum molding or the like It is formed by insert molding inside. Moreover, when the said half mirror process surface is formed in the outer peripheral surface of the said translucent part, it is desirable for the outer peripheral surface of the said translucent part to perform the surface treatment for protecting the said half mirror process surface .

  Thereby, even if a case body is damaged, it is prevented that a half mirror process surface is damaged, and it becomes difficult to produce attenuation of light quantity.

  Examples of the present invention will be described. 1 is a rear perspective view of the door mirror 100, FIG. 2 is an exploded perspective view of the door mirror 100, and FIG. 3 is a sectional view taken along line XX of FIG.

  As shown in FIGS. 1 to 3, a door mirror 100 is attached to a door mirror attachment portion 1 of a vehicle by a door mirror connecting member 2. On one side of the mortar-shaped door mirror housing 3 constituting the door mirror 100 (the rear side of the door mirror when attached to the vehicle), a mirror 4 and an actuator 5 for adjusting the angle of the mirror 4 are disposed. The side turn lamp device 201 and the housing cover 6 are disposed on the other side (the front side of the door mirror when attached to the vehicle).

  The housing cover 6 is for covering a space portion Q (a portion where the side turn lamp device 201 is disposed) provided in the door mirror housing 3, and the curved surface of the door mirror housing 3 in a state of being attached to the door mirror housing 3. It is curved to be continuous with the shape. A translucent portion 7 capable of transmitting light is provided in a belt-like portion from an end portion P1 on the back side of the door mirror 100 to a substantially central portion P2 on the front side in the housing cover 6. Further, the surface of the housing cover 6 other than the light-transmitting portion 7 is subjected to surface treatment such as matte black coating, making it difficult to transmit light.

  The side turn lamp device 201 of the first embodiment will be described. As shown in FIGS. 2 and 4, the side turn lamp device 201 according to this embodiment includes two light sources (in the case of this embodiment, LEDs 8 and 9), and an LED support portion 10 that supports the LEDs 8 and 9. It has. The LED support portion 10 is curved in an arc shape corresponding to the curved shape of the light transmitting portion 7 in the housing cover 6, and is arranged substantially in parallel at a certain distance from the inner peripheral surface of the housing cover 6. Yes. Stepped portions 11 and 12 are formed at two locations in the middle of the LED support portion 10, and the LEDs 8 and 9 are attached to the stepped portions 11 and 12. The LEDs 8 and 9 are turned on by turning on a vehicle direction indicator switch (not shown). The LED 8 is attached to the stepped portion 11 with its light emitting portion substantially along the left-right direction of the vehicle, and the LED 9 is stepped so that the light emitting portion intersects with the vehicle front-rear direction and toward the rear of the vehicle. It is attached to the part 12. In addition, a reflective surface 13 is formed on the surface of the LED support portion 9 facing the housing cover 6 by depositing a metal layer such as aluminum. That is, in the side turn lamp device 201 of the present embodiment, the LED support portion 10 has a reflector function. 3 and 4, the reflecting surface 13 is indicated by a one-dot chain line. In FIG. 2 and subsequent figures, illustration of a control board and elements for operating the side turn lamp device 201 is omitted.

  As shown in FIG. 3, a half mirror process is performed on the inner peripheral surface of the translucent portion 7 provided in the housing cover 6, and a half mirror process surface 14 is formed in this part. 3 and 4, the half mirror processing surface 14 is indicated by a two-dot chain line. This half mirror processing surface 14 is formed by sticking the film which performed the half mirror process, for example. The half mirror treated surface 14 is prepared by setting a film (not shown) subjected to a half mirror treatment in a molding die and molding it simultaneously with the housing cover 6 (film insert molding), or preliminarily preliminarily by vacuum molding or the like. It is formed by insert-molding the molded film into a mold. In the daytime, since the outside is brighter than the inside of the housing cover 6, the light-transmitting portion 7 viewed from the outside of the housing cover 6 has a mirror shape. For this reason, it is difficult to visually recognize the side turn lamp device 201 from the outside of the housing cover 6, and the housing cover 6 and the translucent part 7 are visually recognized as being painted in the same color when viewed from the outside.

  The operation of the side turn lamp device 201 of this embodiment will be described. As shown in FIG. 4, when the vehicle driver turns on the direction indicator switch of the vehicle, the LEDs 8 and 9 are lit. The light 15 emitted from the LED 8 toward the light transmitting portion 7 of the housing cover 6 is reflected by the light 15 a that is transmitted through the half mirror processing surface 14 of the light transmitting portion 7 and emitted outside the vehicle, and the half mirror processing surface 14. And light 15b. In FIG. 4, the refraction display when the light 15 passes through the half mirror processing surface 14 is omitted.

  The light 15b reflected by the half mirror processing surface 14 of the translucent part 7 is directed to the LED support part 10 disposed so as to be opposed to the translucent part 7, reflected again by the reflecting surface 13, and directed to the half mirror processing surface 14. . The light is emitted from the translucent part 7 while repeating this. The light 16 emitted from the LED 9 is also emitted along the same path as described above.

  Here, the half mirror processing surface 14 of the translucent unit 7 and the reflecting surface 13 of the LED instruction unit 10 reflect the light 15 and 16 emitted from the LEDs 8 and 9 repeatedly while reflecting the light 15 and 15. , 16 are arranged to guide the vehicle obliquely rearward. For this reason, the lights 15 and 16 emitted from the LEDs 8 and 9 are condensed on the outer oblique rear region V (see FIG. 6) of the vehicle, which is a legal area.

  Further, since the lights 15 and 16 emitted from the LEDs 8 and 9 are guided to the outer oblique rear region V of the vehicle while being reciprocally reflected between the reflecting surface 13 and the half mirror processing surface 14 at least once, the synergistic effect thereof. An effect (repetitive reflection) is produced. As a result, the attenuation of the amount of light when reflected by the half mirror processing surface 14 can be minimized, and it is not necessary to increase the number of LEDs 8 and 9 or increase the power.

  In the side turn lamp device 201 according to the first embodiment, the translucent portion 7 is provided integrally with the housing cover 6 of the door mirror 100 (that is, part thereof). In a normal state (LEDs 8 and 9 are turned off), the boundary line of the light transmitting portion 7 in the housing cover 6 is difficult to visually recognize. For this reason, when the LEDs 8 and 9 are lit, a third party (pedestrian or driver of another vehicle) feels light emission from an unexpected position in the door mirror 100. That is, in a normal state, it is difficult for a third party to recognize the presence of the translucent portion 7 in the housing cover 6, so that the third party feels that a part of the housing cover 6 suddenly emits light. . As a result, with the side turn lamp device 201 of the present embodiment, the translucent portion 7 can be made to emit light in an unprecedented form while securing the aesthetics of the door mirror 100.

  Next, the side turn lamp apparatus 202 of 2nd Example is demonstrated. In the case of the side turn lamp device 201 of the door mirror 100 of the first embodiment, the translucent part 7 is provided in a part of the housing cover 6. However, like the side turn lamp device 202 of the second embodiment shown in FIG. 5, an opening 18 is provided from the side surface of the housing cover 17 to the front side of the door mirror 100 (front side of the vehicle). The cover body 19 that is attached to the LED support 10 by bonding means such as welding may be disposed in the opening 18 of the housing cover 17. The cover body 19 is made of a material having translucency, and the inner peripheral surface thereof is subjected to a half mirror process to form a translucent portion 21. Thereby, the same effect as the side turn lamp apparatus 201 of 1st Example is show | played.

  And in the case of the side turn lamp apparatus 202 of 2nd Example, there exists an advantage that it can mount | wear with the existing door mirror 100. FIG.

  In the case of the side turn lamp devices 201 and 202 of the first and second embodiments described above, half mirror processing is performed on the inner peripheral surfaces of the light transmitting portions 7 and 21. Thereby, the effect that the half mirror processing surface 14 is hard to be damaged is produced. However, half mirror processing may be performed on the outer peripheral surfaces of the light transmitting portions 7 and 21. In this case, since it is not necessary to perform the half mirror process on the inner surface of the housing cover 6, it is easy to fix the housing cover 6 to the door mirror housing 3. Moreover, in order to protect the half mirror processing surface 14, it is desirable to perform surface treatment (for example, coating with a transparent film) on the outer peripheral surfaces of the light transmitting portions 7 and 21 so as not to impair the light transmitting properties.

  In the side turn lamp devices 201 and 202 of each embodiment described in this specification, the reflective surface 13 is formed on the surface of the LED support portion 10 facing the light transmitting portion 7. Thereby, it becomes unnecessary to provide the reflector having the reflecting surface 13 separately from the LED support portion 10. However, a reflector separate from the LED support portion 10 may be arranged, and the reflecting surface 13 may be formed on the reflector.

2 is a rear perspective view of the door mirror 100. FIG. 2 is an exploded perspective view of a door mirror 100. FIG. It is the XX sectional view taken on the line of FIG. It is operation | movement explanatory drawing of the side turn lamp apparatus 201 of 1st Example. It is a disassembled perspective view of the door mirror 100 with which the side turn lamp apparatus 202 of 2nd Example was mounted | worn. In the conventional door mirror 100 ', it is a figure which shows the light emission area | region (back diagonally outer area | region V).
