Description

  The present invention relates to a vehicle-mounted headlight device that illuminates a road or the like to ensure driver visibility, and a vehicle-mounted headlight device that incorporates a cleaning mechanism.

  A headlamp is indispensable for a vehicle, but the headlamp mounted on the vehicle directly receives mud and dust that the preceding vehicle jumps up. For this reason, it is easy to get dirty, and the illuminance may decrease during traveling. In particular, when driving on a muddy road immediately after the rain, the illuminance decreases rapidly due to the large amount of mud soaring. An abrupt decrease in illuminance during night driving causes a serious obstacle to safe driving.

  Conventionally, various techniques for preventing a decrease in illuminance due to dirt on the headlamp during traveling have been proposed. For example, there are techniques disclosed in Patent Documents 1 to 4.

  As shown in FIG. 19, Patent Document 1 is a technique in which a wiper driving device is disposed in the vicinity of a headlamp, and the front lens and cover surface dirt of the headlamp are swept away by the wiper.

  Patent Document 2 is a technique for cleaning a glass surface by disposing a nozzle on the lower front side of a headlamp glass surface mounted in front of an automobile and spraying a cleaning liquid sprayed from the nozzle onto the glass surface (Patent Patent Document 2). Reference 2 Fig. 2).

  Patent Document 3 is a technique related to the retractable headlight shown in FIG. 20, and a first irradiation position standing on the upper surface of a front part such as a bonnet or a fender, and a second irradiation position stored therein. It is characterized in that it can be switched to In this technology, a headlamp (headlight) is used upright at night, and it is used as a passing light while being stored around the front during the daytime. According to this technology, since the headlamp does not protrude outside the vehicle during the daytime, the design of the vehicle is improved, and the driving resistance can be reduced and the dirt can be reduced.

  Patent Document 4 is a technique obtained by improving Patent Document 3 described above. A headlight that can be moved between a standing state and a retracted state and a rear part of the headlight that can be deployed toward the rear of the vehicle body. And an air inlet provided near the top of the headlight for introducing air into the airbag. According to this technique, even when the headlight is in an upright state, air resistance and lift acting on the vehicle can be reduced.

Japanese Utility Model Publication No. 3-118152 JP-A 64-67450 JP-A-57-182538 JP-A-6-122342

  Each of the above conventional techniques has the following problems. The techniques of Patent Documents 1 and 2 are techniques for cleaning a conventional headlight, and a wiper for cleaning the headlight and the nozzle itself become factors that increase air resistance. Further, the wiper or the like harms the vehicle design and becomes an element that restricts the degree of freedom of the vehicle design (see FIG. 19).

  The technique of Patent Document 3 improves the design of the appearance of the vehicle when the headlight is stored inside the vehicle. However, when the headlight is used (at night), it is necessary to project the light to the outer surface of the vehicle. Therefore, the headlight that projects in the case of a personal accident may seriously damage the human body, which causes a safety problem. There is also a problem that air resistance increases during night driving.

  Although the technique of Patent Document 4 can reduce the air resistance of the lamp projected on the outer surface of the vehicle to some extent, the problem remains that the projected headlamp may seriously damage the human body in the case of a personal injury.

  The present invention solves the above-mentioned problems. It is an object of the present invention to provide a vehicle mounted headlight device that does not increase air resistance, does not cause a projection that damages the human body, does not reduce illuminance due to dirt, and does not restrict the degree of freedom in external design of the vehicle front surface. It is to provide.

  A first invention for solving the above-described problem is a vehicle-mounted head device accommodated inside an outer surface of a vehicle body, and includes a head body incorporating a light emitting element, and a front surface of the head body. A vehicle body element member having one or more light projecting holes positioned in front and the headlight reversibly moved to a position where light emitted from the light emitting element is projected outside the vehicle from the light projecting holes or And a drive section that rotates.

  In this configuration, a light projection hole for projecting light to the outside of the vehicle is provided in the vehicle element member, a heading device is disposed behind the vehicle element member, and the light emitting element is positioned at a position that matches the light projection hole only during lighting. Is adopted. According to this configuration, the main part is accommodated inside the outer surface of the vehicle body, and only the light projection hole exists on the outer surface. The light projecting holes to be present on the outer surface of the vehicle need only be much smaller than the size (outer peripheral frame) of the conventional headlight. Therefore, the degree of freedom in designing the front of the vehicle is greatly increased. Further, the light projection hole does not cause the headlight to protrude from the vehicle body when it is lit, unlike the retractable headlight, but it simply allows light to pass therethrough.

  Therefore, according to the present invention, unlike the retractable headlight, there is no possibility that the running resistance increases at the time of lighting or the protrusion that damages the human body in the case of a personal accident is formed, so that there is no risk of harming the safety. Further, in the present invention, since a headlight having a light emitting element is housed inside the vehicle behind the light projection hole, mud that soars from the road like a conventional headlight provided on the outer surface of the vehicle. Less illuminance reduction due to adhesion.

  Further, according to the above configuration, only when the light is turned on at night or the like, the position of the light emitting element only needs to be matched with the light projection hole, so that dirt when not turned on does not cause a decrease in illuminance. Furthermore, by projecting the same color as the front of the vehicle (the surface of the vehicle component) on the portion that can be seen from the projection hole when not lit, that is, the front part of the front body located behind the projection hole. The presence of holes can be reduced, and the design of the vehicle can be improved.

  Furthermore, according to the above configuration, the vehicle mounting can change the projection angle in multiple stages by providing a plurality of light projection holes and / or providing a plurality of light emitting elements with different optical axis inclinations. A headlight device can be realized.

  Here, the “rotation” in the above configuration means a movement that moves circularly or elliptically in the forward and reverse directions, and “movement” means a movement other than the rotation. The “header” means a device that illuminates the front including the light source, and is used in the widest sense including a headlight, a headlamp, a lamp, a headlamp, and the like.

  According to a second aspect of the invention, in the vehicle mounted headlamp according to the first aspect of the invention, the light projecting hole is an open hole penetrating a vehicle body element member.

  The headlights are installed on the front of the vehicle where the preceding vehicle is most susceptible to mud and dust. The conventional headlamps are covered with a transparent protective member that also serves as part of the outer surface of the vehicle. (See FIG. 19). Therefore, the mud and dust that the preceding vehicle soars adheres to the transparency protection member, and reduces the ability to illuminate the front of the headlamp. However, according to the above configuration, the light projection hole is an open hole penetrating the vehicle body element member, and there is no transparency protecting member on the outer surface of the vehicle, so that the illuminance does not decrease due to dirt.

  In addition, since the floodlight and the rainwater freely pass through the light projection hole formed of the through hole, a cleaning effect on the front surface of the head body by the travel wind and rainwater can be expected. On the other hand, if the projection hole is an open hole, mud or the like that the preceding vehicle soars may reach the front of the front body, which may contaminate the front of the front body. Does not cause a decrease in illumination of the headlight. This is because the vehicle-mounted head device of the present invention employs a method in which the head body is reversibly moved or moved, and the light emitting element and the light projection hole are aligned only during lighting. This is because the soiled part at the time of lighting (daytime) is different from the position at the time of lighting (position of the light emitting element).

  Furthermore, in the above configuration, by providing an appropriate gap between the vehicle element member and the front of the front body, the rate at which mud or the like reaches the front of the front body can be reduced. Dirt on the front of the illuminator can be reduced. From the above, according to the above configuration, it is possible to provide a vehicle-mounted head device that reduces the head function deterioration (decrease in illuminance) due to dirt or the like.

  According to a third aspect of the present invention, in the vehicle mounted headlamp according to the second aspect of the present invention, the front body is a protective member having an emission region that transmits light and a non-emission region that does not transmit light. Is characterized by being covered.

  According to this configuration, when projecting light, it is possible to associate the emission region with the projection hole and turn on the light emitting element, and when not lighting other than this, it is possible to associate the non-emission region with the projection hole. If it does in this way, the fall of the headlight function by mud dirt etc. can be controlled reliably. Further, the presence of the headlight can be prevented from being perceived during non-lighting (daytime) by coloring the non-injection region, applying a pattern, or making the material feeling the same as that of the vehicle element member. In addition, the design and unity of the vehicle exterior can be improved.

  According to a fourth aspect of the present invention, in the vehicular head mounted device according to any one of the first to third aspects of the invention, the driving unit reversibly moves or rotates the head body, thereby The body is positioned at a first position where the optical axis of the light emitted from the light emitting element passes through the light projection hole, or the non-emission area is positioned at a second position facing the light projection hole. Features.

  In this configuration, when the driving unit reversibly moves or rotates the headlight to the “first position”, the optical axis of the light emitted from the light emitting element coincides with the light projection hole. When the light emitting element emits light at this stage, the front of the vehicle is illuminated. On the other hand, when there is no need for lighting such as in the daytime, the driving unit is driven to place the headlight in the “second position”. The “second position” is the position where the light projection hole and the non-irradiated area overlap, and the non-irradiated area can be seen from the light projecting hole, so by applying any design and color to the non-irradiated area, Can be increased.

  Here, the “optical axis” refers to the center line of the bundle of light emitted from the light emitting element, and is used to include an extended line obtained by extending the narrowly defined optical axis in the light traveling direction. In each of the above configurations, for example, a lighting switch provided in the driver's seat of the vehicle is connected to the drive unit and / or the light emitting element. It moves or rotates to “position”, and the issuing element is energized. On the other hand, when the lighting switch is turned off, the system is configured to move or rotate to the “second position” and remain in this position until the lighting switch is turned on next time.

  According to a fifth invention, in the vehicle mounted headlamp according to the fourth invention, the vehicle body element member has two light projecting holes spaced apart from each other, and the head body has the two light projecting holes. A light emitting element for a high beam corresponding to any one of the light emitting elements and a light emitting element corresponding to another light projecting hole, wherein the light projecting light is directed downward from the light emitting element for high beam. A driving unit connected to and fixed to the headlight body, and the front body moves or rotates to correspond to the tip of each light-emitting element. It is made to oppose a light projection hole.

  In this configuration, one is a high beam projection hole for illuminating the far front, and the other is a low beam projection hole for illuminating the front closer to the high beam. The two light emitting elements for the high beam and the low beam corresponding to these two light projection holes are compared with the high light beam at the light projection position (the first position). -The projector light for the projector is arranged so as to incline downward. In addition, the drive unit is configured to move the head body to a position ("first position") where the tip of each light emitting element faces the corresponding light projection hole ("first position"). Thereby, the light emitted from the light emitting element can be projected outside the vehicle (road) through the light projection hole.

  Further, in the vehicle mounted headlamp with this configuration, the two light emitting elements and the two corresponding light projecting holes can be set so as to simultaneously coincide at the same “first position”. Alternatively, the spatial positional relationship may be set so as to individually match at different “first positions”. In the case of the former setting, the energization to the light emitting element is selectively switched to either one at the same “first position”, thereby instantaneously switching between the high beam and the low beam. Can do.

  Further, in this configuration, it is not necessary to dispose the light beam projection hole below the high beam projection hole. The two light projecting holes may be arranged in any of the vertical direction, the horizontal direction (horizontal direction arrangement), and the oblique direction.

  According to a sixth aspect of the present invention, in the vehicle mounted headlamp according to the fifth aspect of the present invention, a spatial positional relationship between the light projecting holes and the light emitting elements indicates that the light emitted from the high beam light emitting elements is light. The light emitted from 0 to 0.2 degrees below the vehicle horizontal reference plane, and the light emitted from the light emitting element for the lobe beam is 0.2 to 5 degrees below the vehicle horizontal reference plane. It is regulated so that it is projected.

  Here, the “vehicle horizontal reference plane” refers to a plane parallel to a plane including the center point of all the wheels that support the vehicle (hereinafter referred to as a vehicle horizontal plane) and including the center point of the light projection hole.

  According to a seventh aspect of the present invention, in the vehicle mounted headlamp according to the fourth aspect of the invention, the vehicle element member is provided below the high beam projection hole and the high beam projection hole. One or more lobe beam projection holes, the head body has one light emitting element, and a rear end portion of the head body is connected and fixed to the drive unit. The front portion of the imaginary line connecting the movable center point of the rear end portion to the center point of the area of the front surface with the rear end portion as a base end by the driving unit is tilted vertically with respect to the movable center point. By moving the body, the tip side of the light emitting element is made to face the high beam projection hole or the low beam projection hole.

  In this configuration, the rear end portion of the head body is used as the base end, and the head body is moved up and down so that the head body is inclined. When the front of the head is tilted downward, the light emitting element disposed inside the head is also tilted downward. Therefore, when a plurality of light projecting holes are arranged on the locus that the light emitting element tip extension line traces the vehicle element member by this movement, the higher light projecting hole functions as a high beam light projecting hole. A light projecting hole provided at a low position functions as a light projecting hole for a beam. Therefore, for example, if three light projection holes are provided, three light projections of a high beam, a middle beam, and a beam can be formed. That is, according to this configuration, it is possible to realize a vehicle-mounted head device that can change the inclination of head light in multiple stages with a simple structure.

  According to an eighth aspect, in the vehicle mounted headlamp according to the seventh aspect, an inclination angle of the imaginary line is -0.2 to -5 degrees.

  With this configuration, for example, the inclination angle of the high beam with respect to the vehicle horizontal reference plane is set to zero, and the inclination of the low beam with respect to the vehicle horizontal reference plane is set in multiple steps within a range of -0.2 to -5 degrees. Set to. Accordingly, for example, when traveling on an uphill, traveling on a downhill, or traveling on an urban area, it is possible to appropriately select the angle of the projection light.

  According to a ninth invention, in the vehicle-mounted head device according to any one of the first to third inventions, the vehicle element member has one or more light projecting holes, and the head body includes: It has a light emitting element with a variable mechanism that changes the inclination of the light emitting element itself, and when the driving unit rotates the light emitting element with the variable mechanism to a position corresponding to the light projection hole. In some cases, the optical axis of the light emitting element with the variable mechanism is restricted to a specific light projection angle.

  According to a tenth aspect, in the vehicle mounted headlamp according to any one of the first to ninth aspects, the light-emitting element includes a semiconductor laser.

  The semiconductor laser is excellent in luminous efficiency, can obtain a larger luminous intensity with less electric power, and has good light directivity. Therefore, a light-emitting element having a semiconductor laser is advantageous in that the head body can be made compact and energy-saving, and the projection hole can be made small.

  The light emitting element having the semiconductor laser in this configuration may be any light emitting element having a semiconductor laser as a light source, and does not mean one having a single physical semiconductor laser. It may have a large number of semiconductor laser groups.

  In addition, the light emitting element having the semiconductor laser in this configuration is provided with a diffusion layer for diffusing the light emitted from the semiconductor laser in front of the semiconductor laser in order to increase the head area. preferable.

  Here, in the case of a light emitting element composed of a semiconductor laser group or a light emitting element provided with a light scattering layer, the “optical axis” is a line connecting the area center points in the cross section perpendicular to the traveling direction of the emitted light beam. .

  An eleventh aspect of the present invention is the vehicle mounted headlamp according to any of the first to tenth aspects of the present invention, in the vicinity of the front surface of the headlight and at a position that does not interfere with the light projection from the light projection hole. A cleaning member for cleaning the front surface of the head body is disposed.

  A twelfth aspect of the invention is the vehicle mounted headlamp according to the eleventh aspect of the invention, in which the cleaning member uses a movement when the headlight moves or pivots to move the front face of the headlight. It is a member that wipes off and / or wipes off dirt, and is arranged on the inner side surface of the vehicle member so as to be in contact with the front face of the front body.

  In a series of the present invention, the headlight is moved or rotated reversibly so that the light emitting element and the light projecting hole are aligned at any time, and the light emitted from the light emitting element is projected from the light projecting hole to the outside of the vehicle. Adopts a configuration that shines. Therefore, when a cleaning member for cleaning the front surface of the head body is disposed in the vicinity of the front surface of the head body and at a position that does not interfere with the light projection from the light projection hole, each time the head body moves or rotates. It is possible to automatically clean the front of the head.

  A thirteenth aspect of the invention is the vehicle mounted headlamp according to the eleventh aspect of the invention, wherein the cleaning member is a fluid jet that blows cleaning liquid and / or compressed air onto the front face of the head. .

  In this configuration, a fluid ejection port that is a part of an apparatus including a fluid ejection machine is disposed in the vicinity of the front surface of the head body. When cleaning fluid and / or compressed air is ejected from the fluid ejection port and sprayed onto the front surface of the head body, the cleaning effect is enhanced.

  Here, as the wiping and / or wipe-off member in the above configuration, for example, a brush, a sponge, a cloth, a cotton cloth, a liquid sprayer spout, an air spout spout, a wiper, an ultrasonic irradiator, etc. The “fluid ejection port for spraying the cleaning liquid and / or the compressed air on the front surface of the head body” is an aspect of the scraping member. These members can be used in combination. For example, the cleaning effect can be further enhanced by combining different elements such as a brush and a liquid sprayer nozzle.

  According to the present invention, it is possible to realize a vehicle mounted headlight device that does not increase air resistance, does not cause a projection that damages the human body, does not reduce illuminance due to dirt, and does not restrict the degree of freedom in the appearance design of the front surface of the vehicle. be able to.

  In addition, according to the present invention, a vehicle-mounted head device that automatically cleans the front surface of the head body (injection region and non-injection region) each time switching between lighting and non-lighting with a simple mechanism is realized. be able to. Since the cleaning member according to the present invention is not disposed outside the vehicle like the wiper according to the prior art, it does not impair the vehicle design, safety, and running performance.

  In addition, according to the present invention, it is possible to realize a heading device that can change the inclination of headlight in multiple steps with a simple structure having one light emitting element. Therefore, according to the present invention, it is possible to provide a vehicle-mounted head device that allows the driver to arbitrarily select an appropriate beam suitable for the road condition.

<First Embodiment>

  The first embodiment will be described with reference to FIGS. FIG. 1 is a front external view of a vehicle (100) incorporating a vehicle-mounted headlamp according to the present invention. In FIG. 1, reference numeral 1 denotes a hood cover. In this example, the hood cover is a vehicle element member.

  Reference numerals 2 and 3 are projection holes, reference numeral 2 is a high beam projection hole, and reference numeral 3 is a low beam projection hole. The pair of light projecting holes includes through holes formed in a bonnet cover (vehicle element member 1) covering the front surface of the vehicle 100.

  Two light projecting portions 101, 102 including a pair of light projecting holes 2, 3 including through holes are provided on the left and right sides of the front surface of the vehicle 100. In the bonnet (behind the light projection holes 2 and 3), there are a head body that is a main body portion of the head device that projects light onto the light projecting sections 101 and 102, and a drive unit that drives the head body. Stored.

  FIG. 2 is a schematic cross-sectional view of the headlight device taken along a plane passing through the center point of the light projection holes 2 and 3 of the light projecting unit 102. Each element of the headlamp will be described with reference to FIG. In FIG. 2, reference numeral 4 denotes a headlight, reference numeral 5 denotes a high beam light emitting element, and reference numeral 6 denotes a low beam light emitting element. The head body 4 is a container for incorporating a light emitting element, but if necessary in relation to the light emitting element, the inner surface may be a reflecting mirror or filled with an inert gas.

  The light-emitting elements 5 and 6 in this embodiment are configured to include a semiconductor laser element as a light source and a diffusion layer disposed on the tip side thereof. The light-emitting elements 5 and 6 themselves are lit by a support member (not shown). It is fixed in the body 4. Examples of the support member include, but are not limited to, a bridge member in which both ends (foot portions) are fixed to the wall surface of the headlight 4 and the light emitting element is fixed and supported at the center portion.

  Reference numeral 8 denotes a drive unit including a drive motor, and the head body 4 is fixed to the drive unit 8 via the rear end portion 7 so as to be rotatable.

  FIG. 3 is a schematic front view of the head body 4 as viewed from the front. A protective member 9 is disposed on the front surface of the headlamp 4. The protective member 9 has emission regions 10 and 10 (light transmission portions) that transmit light emitted from the tip of the light emitting element, and a non-emission region 11 that is the remaining portion. The protection member 9 is made of, for example, a transparent plastic, and the non-injection region 11 is colored to give a texture similar to that of the surface of the vehicle element member 1 (bonnet cover), for example. This reduces the presence of the projection holes 2 and 3 when not projecting, and improves the aesthetic appearance of the front surface of the vehicle.

  The front body 4 and the drive unit 8 are only required to be fixed to the vehicle while being accommodated in the hood of the vehicle 100, and there are no particular restrictions on the fixing method. Further, although the front body 4 does not necessarily require a cover, it may be stored in a storage container 12 that covers the entire front body as shown in FIG.

  FIG. 4 is a schematic cross-sectional view showing a state in which the head device is covered with the storage container 12. As shown in FIG. 4, the storage container 12 is preferably provided with a hole 13 for escaping traveling wind, water, dust, and the like entering from the light projection hole to the outside of the vehicle. The material of the storage container 12 is preferably plastic or aluminum because of its light weight. Further, the method for fixing the storage container 12 is not particularly limited as long as it can be safely and stably supported and fixed inside the bonnet.

  Next, the spatial positional relationship between the light emitting element 5 for the high beam and the light emitting element 6 for the low beam, which are constituent elements of the headlight 4, and the light projection holes 2 and 3 will be described. Here, the high beam is light that illuminates the farther front, and the low beam is light that illuminates the front closer to the high beam. Since a vehicle traveling on a general road requires downward light that does not dazzle the driver of the oncoming vehicle, this requirement is taken into account when setting the inclination of the light emitting element 6 for the lobe. .

  In the first embodiment, two light projecting holes 2 and 3 that are separated in the vertical direction are provided in a hood cover that is a vehicle body element member. Further, in relation to these light projecting holes 2 and 3, the head body 4 has its center of rotation (rotation axis) higher than the light projecting hole 2, and the front surface of the head body 4 is always projected. The optical holes 2 and 3 are positioned and arranged so as to be rotated in a state of facing each other. Further, the light emitting elements 5 and 6 inside the head body 4 are arranged on one imaginary straight line extending from the rotation center point of the front surface of the head body to the outer periphery (one radial line in the case of a circle). The light emitting tips are aligned and positioned so that the distance between the two light emitting tips corresponds to the light projecting holes 2 and 3.

  Furthermore, when the light emitting elements 5 and 6 are aligned with the light projecting holes 2 and 3 (this position is the “first position” at which the light from the light emitting elements can be projected), for high beam use. The optical axis 110 of the projection light from the light emitting element 5 is 0 to −0.2 degrees with respect to the vehicle horizontal reference plane, and the optical axis 111 of the projection light from the light emitting element 6 for the lobe is the vehicle horizontal reference. The inclination of each light emitting element is adjusted so as to be −0.2 to −5 degrees, preferably −0.5 to −1 degrees with respect to the surface, and is fixed inside the headlamp 4.

  With such a structure, when the head body 4 is rotated around the rotation axis, the light emitting element 5 for the high beam and the light emitting element 6 for the lobe disposed inside the head body 4 Are simultaneously aligned with each of the projection holes 2 and 3.

  The light projecting holes 2 and 3 are usually provided at a height of about 1 m from the tire contact surface, and the distance between the pair of light projecting holes is 1 to 2 cm. The shape of the projection hole is usually a circle or an ellipse having a diameter of about 2 to 4 cm, but may be a square or a polygon. If the shape of the projection hole is an ellipse in the vertical direction, the angle of the projection light that illuminates the ground can be easily changed.

  Here, in the first embodiment, the light projection hole is formed in the bonnet cover, but the present invention is not limited to this. Any part that is convenient for headlighting and that has a marginal space that can accommodate the headlight and the drive unit inside the vehicle may be used. In the first embodiment, the upper hole is the high beam projection hole 2 and the lower hole is the low beam projection hole 3, but the present invention is not limited to this. It may be upside down, and a pair of light projecting holes may be arranged in the left-right direction. However, in order to change the relationship between the pair of holes and the type of beam, it is necessary to adjust the spatial positional relationship of each element in relation to the optical axis of the light emitting element incorporated in the headlight.

  FIG. 5 shows a vehicle external view and an enlarged perspective view when a pair of light projecting holes are provided in the left-right direction. The enlarged perspective view of FIG. 5 shows the positional relationship between the light projecting holes 2 and 3 on the outside of the vehicle and the pair of light emitting elements on the inside of the vehicle. FIG. Illuminates. In FIG. 5, a broken line ◯ indicating the light projecting unit 102 represents the outline of the front surface of the head body 4 accommodated in the hood.

  Next, a method for driving the headlamp will be described with reference to FIGS. FIG. 2A shows a non-lighting state in which the non-emission region 11 is opposed to the pair of projection holes 2 and 3 (this position corresponds to a “second position”). In the first embodiment, the non-injection region 11 has the same color (or texture) as the color of the outer surface of the bonnet cover. As a result, the light projecting holes 2 and 3 when not lit melt into the color of the hood cover. Thus, the design of the vehicle is not harmed by the presence of the projection hole.

  FIG. 2B shows a state in which the emission regions 10 and 10 face the pair of light projection holes 2 and 3 (a state at the “first position”), and this state is a lightable state. Here, the driving motor in the driving unit 8 is connected to a power source (not shown), and the light emitting elements 5 and 6 are connected to a vehicle power source (for example, a storage battery) by a lead wire passing through the rear end portion 7. (Not shown). And the lighting switch which controls electricity supply to these is provided in the driver's seat of the vehicle 100. FIG. There are three lighting switches, for example, lighting OFF, high beam ON, and low beam ON.

  For example, when the headlight 4 is in the state shown in FIG. 2A, when the driver turns on the high beam lighting switch, the driving motor changes the state from FIG. 2A to FIG. 2B. The head body 4 is rotated to the state. At the same time or simultaneously with the ON state, the high beam light emitting element 5 is turned on and the high beam is projected forward of the vehicle.

  When the headlight 4 is in the state shown in FIG. 2A, the same operation is performed when the lobe switch is turned on, and the lobe is projected forward of the vehicle. (FIG. 2c).

  On the other hand, when either the high beam switch or the low beam switch is in the ON state (when the head body 4 is in the state shown in FIG. 2B or 2C), the high beam ← → When the beam is switched, only the beam is switched immediately. Further, when the lighting switch is turned off in either the high beam ON state or the low beam ON state, the energization to the light emitting elements 5 and 6 is released and the head body 4 rotates. Thus, the state returns to the state of FIG.

  The rotation angle when the lighting switch is turned on and off is, for example, 180 degrees and is rotated in one direction. However, the rotation angle only needs to be able to completely exchange the positions of the lighting region 10 and the non-lighting region 11, and does not need to be 180 degrees. For example, the rotation angle between the “first position” and the “second position” is set to 90 degrees, and the “first position” and the “second position” are switched by rotation of 90 degrees in the forward / reverse direction. You may do it.

  As described above, in the first embodiment, two light projecting holes are provided in the vehicle element member (bonnet cover), and the light emitting element for the high beam and the light emitting element for the low beam are referred to as the “first light emitting element”. The structure was made to match at the same time in “position”. Therefore, when traveling at night, it is preferable to appropriately switch between the high beam and the low beam while the head body 4 is stopped at the first position. On the other hand, during daytime running, in principle, it is stopped at the “second position” where the non-emission area 11 is positioned in the light projection holes 2 and 3. Here, as described above, the non-injection area 11 has the same color as that of the hood cover, so that the appearance design in the daytime when the vehicle appearance can be clearly seen can be harmed by the presence of the projection hole. Absent. In addition, since the non-emission area 11 is a portion that does not project light, dirt on the front surface of the front body during daytime running does not cause a reduction in the headlight function.

  The light projecting holes 2 and 3 may be covered with a light transmissive member. Further, the switching mode of the lighting switch may be appropriately determined. For example, lighting OFF, high beam ON, low beam ON, high beam & low beam ON may be used. The strength may be changed in multiple stages.

Second Embodiment
The second embodiment is different from the first embodiment in that a cleaning member for cleaning the front surface of the head body 4 is disposed in the vicinity of the head body 4 in the bonnet. This is the same as in the first embodiment.

  A second embodiment will be described based on FIGS. FIG. 6 is a schematic cross-sectional view when the head device mounted on the vehicle is cut along a plane including the centers of the light projection holes 2 and 3 of the light projecting unit 102 as in the case of the first embodiment. In the figure, reference numeral 14 denotes a brush which is a cleaning member. The brush 14 is fixed to the inner surface of the hood cover (vehicle element member 1) so as to be able to contact the front surface 9 of the head body.

  Reference numerals 15 to 19 denote a cleaning mechanism having a fluid ejector. The cleaning mechanism in the second embodiment is a jet outlet 15 (cleaning member) for ejecting a cleaning liquid, a transport tube 16 for transporting the cleaning liquid, and a cleaning liquid. A fluid ejector 17 (injection pump) and a storage tank 18 for storing a cleaning liquid 19 are configured. The fluid ejector 17 is connected to a cleaning liquid injection button (not shown) provided in the driver's seat of the vehicle 100. When the cleaning liquid injection button is turned on, the cleaning liquid is supplied from the jet port 15 to the front body front surface 9. It comes to be ejected toward.

  Reference numeral 19 represents cleaning water stored in the storage tank 18.

  FIG. 7 is a front external view of a vehicle on which the vehicle mounted heading device according to the second embodiment is mounted. The enlarged perspective view shown on the left side of the drawing is a plan perspective view showing the positional relationship between the light projection holes 2, 3, the front of the head body, and the brush 14. A broken line ◯ in the enlarged perspective view shows the outline of the head body, FIG. 7A shows a non-lighting state, and FIG. 7B shows a lighting state. In the enlarged perspective view of FIG. 7A, the light emitting elements 5 and 6 are not drawn, but the light emitting elements 5 and 6 are present in the back of the brush 14.

  The lighting / non-lighting operation of the headlight device according to the second embodiment is the same as that described in the first embodiment. When the lighting switch is OFF, the state shown in FIG. 6A is obtained. When the lobby lighting switch is turned ON, the state shown in FIG. 6B is obtained. That is, each time the lighting switch is turned ON / OFF, the head body 4 rotates and the head body front surface 9 moves. At this time, the brush 14 arranged in contact with the head body front surface 9 is used for the head head. Dirt on the front surface of the body (both irradiation region 10 and non-irradiation region 11 which are the tip portions of light emitting elements 5 and 6) is cleaned.

  Further, when the driving vehicle turns on the cleaning liquid ejection button, the cleaning liquid is ejected from the ejection port 15 and the front body 9 is cleaned with the cleaning liquid. In addition, the cleaning liquid can be ejected in synchronization with ON / OFF of the lighting switch, and in this way, the brush cleaning effect is further enhanced.

  In the above description, the brush is used as a member for wiping and / or wiping off the front surface of the head. However, a sponge, cloth, cotton, paper, or a driven wiper can be used instead of the brush. In the above description, the cleaning liquid is jetted and cleaned. However, a compressed air may be jetted instead of the cleaning liquid.

  Further, since the conventional vehicle is provided with a cleaning liquid supply mechanism (a cleaning liquid ejector, a cleaning liquid tank, etc.) for supplying a cleaning liquid for cleaning the windshield, the cleaning liquid ejector and the cleaning liquid tank provided in the conventional vehicle are stored in the above-described storage. The tank 18 and the cleaning liquid 19 may be used together.

  Moreover, although the example of element arrangement shown in FIGS. 6 and 7 in which the brush 14 is positioned on the upper side is shown above, the arrangement of each element depends on the vehicle height, the mounting position of the light projection hole, and the storage space in the bonnet. It may be set appropriately in consideration of the circumstances. For example, as shown in FIGS. 8A and 8B, a pair of light projecting holes 2 and 3 are provided at a position higher than the rotation center axis of the head body 4, and a cleaning member (brush 14, jet nozzle 15) is provided. May be arranged at a position lower than the rotation center axis of the head body 4.

  In the vehicle-mounted headlamp shown in FIG. 8, when the headlight 4 is rotated and the pair of light emitting elements 5 and 6 located inside thereof is positioned above, the “first position”). In this position, it is possible to project light outside the vehicle. In addition, the inner light emitting element functions as the lobe light emitting element 6, and the outer light emitting element functions as the high beam light emitting element 5.

  Further, since the front surface of the headlight does not necessarily have to be flush, it may have a shape in which the tip of the light emitting element protrudes as shown in FIG. The brush 14) can also be provided with a pair of light projecting holes on the side.

<Third Embodiment>
The third embodiment relates to a vehicle-mounted head device that switches between a lighting state and a non-lighting state by linearly moving the head body in the vertical direction using a rack and pinion device. A third embodiment will be described with reference to FIGS. The third embodiment is substantially the same as the second embodiment except that the head body is reciprocated in the linear direction in the vertical direction. Therefore, members similar to those in the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

  FIG. 11 is a schematic cross-sectional view when cut along a plane including the optical axis direction line and a mounting hole of the rack and pinion device, where (a) is a non-lighting state and (b) is a roaming non-lighting state. Indicates. In FIG. 11, reference numerals 41 and 42 denote a high beam head body and a low beam head body incorporating one light emitting element, and a semiconductor laser is used as a light source of the light emitting element. ing.

  Reference numeral 20 is a rack gear, and 21 is a pinion gear that moves the rack gear. Two mounting holes for attaching the head bodies 41 and 42 are provided on the upper end side of the rack gear 20, and the high beam head body and the low beam head body are attached to the mounting holes, The light emitting elements of these headlights can be energized.

  FIG. 12 is a diagram showing an outline of the rack and pinion device, and is a schematic cross-sectional view in a direction orthogonal to the linear motion direction of the rack gear. In this figure, reference numeral 22 denotes a motor that rotates the pinion gear 21 in the forward and reverse directions, reference numeral 23 denotes a motor support that supports the motor 21, and reference numeral 25 denotes a vehicle body member constituting the vehicle 100 (one of the vehicle bodies). ), 24 is a rack vehicle body fixing member that supports and fixes the rack gear 20 to the vehicle body member 25.

  As shown in FIGS. 11 (a) and 11 (b), a brush 14 and a cleaning liquid jet port 15 are disposed above the light projection hole 2.3, and a series for ejecting the cleaning liquid from the jet port 15 to the periphery thereof. (Transport tube 16, fluid ejector 17, cleaning liquid tank 18) are arranged.

  Further, the surface of the rack gear 20 on the vehicle element member 1 side (the surface that can be seen from the light projection hole when not lit) is given the same color as the bonnet cover. The surface to which this color is applied functions in the same manner as the non-irradiated region in the first embodiment.

  As apparent from FIGS. 11 and 12, in the vehicle mounted headlamp according to the third embodiment, when the rack gear 20 moves to the “first position” below due to the rotation of the pinion gear, The optical axes of the light emitted from the bodies 41 and 42 coincide with the light projection holes 2 and 3. At this position, current is supplied to one of the light emitting elements (not shown) in the headlights 41 and 42, and the high beam or the low beam is projected outside the vehicle.

  On the other hand, when the lamp is not lit, the pinion gear is rotated in the reverse direction to move the rack gear 20 to the upper “second position”. The front surface of the front body is cleaned by the brush 14 that is in contact with the front surface of the front body at every vertical movement. Further, the front surface of the head body is cleaned with a cleaning liquid sprayed as necessary.

  In the first and second embodiments, the high-beam light-emitting element and the low-beam light-emitting element are incorporated in one headlight. In the third embodiment, one light-emitting element is provided. Two small headlights are used. The reason for this is that in the first and second embodiments in which the spatial position of the light emitting element is changed by the rotation of the head body, it is reasonable to rotationally drive one head body incorporating two light emitting elements. On the other hand, in the case of a method in which the position of the light emitting element is changed by a linear reciprocating motion in the vertical direction, there is no inconvenience even if two individual heads are arranged.

  However, the lighting state can also be obtained by linearly moving one head body (for example, the head body 4 in FIG. 6) incorporating the light emitting element for high beam and the light emitting element for low beam in the upper limit direction. You can change the position of the non-lighting state. In the present specification, the head body and the light emitting element are distinguished from each other. However, in the case of the third embodiment, the head body may be the light emitting element itself.

<Fourth embodiment>
The fourth embodiment relates to a vehicle-mounted head device that projects a high beam and a low beam with a single light emitting element by tilting the front end side of the light emitting element. A heading device according to a fourth embodiment will be described with reference to FIGS.

  In this embodiment, one light emitting element 26 is provided in the headlight 43, and the vehicle body element member 1 has a high beam projection hole 2 and a low beam projection that are spaced apart in the vertical direction. A hole 3 is provided. In this embodiment, the head body 43 is attached to the drive motor 8 in a state in which the rotation shaft 29 is tilted forward with respect to the vehicle horizontal plane, and the head body 43 is rotated. By matching one light emitting element with the high beam projection hole 2 and the low beam projection hole 3, the high beam and the low beam are selectively projected.

  Based on FIGS. 13-15, the detail of the vehicle-mounted headlamp apparatus concerning 4th Embodiment is demonstrated. FIG. 13A shows a state in which the light emitting element 26 in the headlight 43 is located at a position matching the high beam projection hole 2. In the state of FIG. 13A, the light emitting hole 2 and the light emitting element 26 are arranged so that the light of the light emitting element 26 can pass through the light projecting hole 2 and the optical axis of the light emitting element 26 is inclined downward by 0 to 0.2 degrees. The spatial positions of the light emitting element and the head body 26 are determined and arranged.

  FIG. 13B shows a state in which the headlight 43 is located at a position that matches the beam projection hole 3. In the state shown in FIG. 13B, the light projecting hole 2 and the light emitting element so that the light from the light emitting element 26 can pass through the light projecting hole 3 and the optical axis of the light emitting element 26 is inclined downward by 0.2 to 5 degrees. 26 and the spatial positions of the light emitting element and the head body 26 are adjusted and arranged in advance.

  Since both of FIGS. 13A and 13B are positions where light can be projected, the “first position”, that is, the “first position” where the optical axis of the light emitted from the light emitting element passes through the light projecting hole. There are two “positions of 1”.

  FIG. 14A is a schematic cross-sectional view showing a state where the light emitting element 26 is located at a position where it does not match any of the light projecting holes 2 and 3, that is, at a “second position”. In this figure, since the light emitting element 26 exists in the back of the cross section, the light emitting element 26 is drawn with a broken line. FIG. 14B is an enlarged perspective view around the light projection hole when viewed from the front of the vehicle (the outer surface side of the vehicle element member 1).

  As shown in FIG. 14 (b), the light emitting element 26 is located at a position not visible from the light projecting holes 2 and 3 (next to the light projecting holes 2 and 3), which is the same as described in the first embodiment. The non-emission area is located at a position that matches the projection holes 2 and 3. Reference numeral 43 represents the contour of the headlight 43.

  FIG. 15 is a diagram for explaining the principle of the fourth embodiment. Based on FIG. 15, the relationship between the rotation of the head body 43 and the inclination of the light emitting element 26 will be described. In FIG. 15, reference numeral 27 denotes an optical axis extension line of the high beam, reference numeral 29 denotes a front body rotation axis, reference numeral 28 denotes a low beam optical axis extension line, and θ denotes the front body rotation axis and the high beam. It is an angle with the optical axis extension line or the beam optical axis extension line.

  In the fourth embodiment, as shown in FIGS. 13 to 14, the light projecting holes 2 and 3 are arranged apart from each other in the vertical direction, and the light projecting hole 2 disposed on the upper side functions as a light projecting hole for a beam. The light projecting hole 3 arranged on the lower side is set to function as a light beam projecting hole. When the light emitting element 26 comes to the top, the tip of the light emitting element and the high beam projection hole 2 coincide with each other, and when the light emitting element 26 comes to the lowest position, it coincides with the low beam projection hole 3. It is configured as follows. The vehicle-mounted head device according to the fourth embodiment having this structure is configured as follows, for example.

  The rear end portion of the front body 43 is connected and fixed to the drive motor 8 so that the rotation axis of the front body 43 is inclined by θ with respect to the vehicle horizontal plane 30. Under this condition, when the head body is rotated and the light emitting element 26 is positioned at the uppermost position, the optical axis (27) of the light emitting element 26 is α (preferably 0 to 0.2 degree) with respect to the vehicle horizontal plane 30. Thus, the light projection hole 2 is provided at a position where the optical axis extension line 27 passes.

  Next, the light projection hole 3 is provided on the optical axis extension line 27 when the light emitting element 26 is positioned at the lowest position by rotating the head body 43. The tilt angle of the optical axis indicates a downward angle with respect to the light traveling direction. Further, the optical axis inclination when the light emitting element 26 is located at the lowest position is preferably 0.2 to 5 degrees (this inclination is β).

  The projection angle of the high beam under the above conditions is [α]. The light beam projection angle is [α + 2θ] (see FIG. 15). Thus, for example, if θ is 0.5 degrees and α is 0 degrees, the high beam projection angle is 0 degrees, and the low beam projection angle is 1.0 degrees.

  As is obvious from the principle of FIG. 15, according to the method according to the fourth embodiment in which the rotation axis is inclined, two or more different inclinations are provided by providing two or more light projecting holes on the movement locus of the light emitting element 26. Can be emitted. For example, if third and fourth light projecting holes are provided on the circumference passing through the center point of the light projecting holes 2 and 3, before the first to fourth steps of inclined light can be emitted. A lighting device can be configured.

  Of course, in this method, a cleaning member can be added.

<Fifth Embodiment>
The fifth embodiment relates to a method of changing the angle of light projection by directly tilting the light emitting element itself in the vertical direction. A heading device according to a fifth embodiment will be described with reference to FIGS.

  FIG. 16 is a schematic cross-sectional view for explaining a method of tilting the light emitting element. As shown in FIG. 16, the light emitting element 31 is disposed in the head body 44. The light emitting element 31 is fixed to the inner wall of the headlight 44 by a movable support shaft 33 as shown in FIG.

  A vertical movable pin 32 is attached to the rear end side of the light emitting element 31. The vertically movable pin 32 is a member that moves the rear end side of the light emitting element 31 in the vertical direction. The movable support shaft 33 is a support shaft that extends from both sides of the light emitting element 31 to the inner wall of the head body 44. The light emitting element 31 has a distal end side that moves forward and backward with the movable support shaft 33 as a center of rotation in accordance with the forward and backward movement of the vertical movable pin 32. It has come to swing.

  The vertically movable pin 32 is not particularly limited as long as it can expand and contract or move in the vertical direction. For example, a mechanism that converts forward / reverse rotation of a small motor into linear motion of forward and backward movement may be used.

  The relationship between the vertical movement of the vertical movable pin 32 and the projection angle will be described. FIG. 16A shows a state in which the high beam (27) is projected. This state is formed when the vertically movable pin 32 is retracted (or shortened). FIG. 16B shows a state in which the beam (28) is projected, and this state is formed when the up and down movable pin 32 moves forward (or extends). In FIG. 16 (b), δ is a difference between the high beam and the low beam projection angle. In the high beam in FIG. 16 (a), the light projection angle with respect to the vehicle horizontal reference plane is set to about 0 to -0.2 degrees, and the light beam projection angle is -0.2 to-. It is set to about 5 degrees.

  Based on Fig.17 (a)-(c), the usage condition in the case of mounting the head apparatus concerning this embodiment in a vehicle is further demonstrated. As shown in FIGS. 17A to 17C, in the fifth embodiment, the light emitting element 31 is directly tilted by the vertically movable pin 32, and the headlight itself (44) is also driven by a drive motor (drive unit). 8), and the structure can be cleaned by the cleaning members 14 and 15 disposed on the front face of the head body. A control system such as a lighting switch not shown in FIGS. 17A to 17C is the same as that of the second embodiment.

  17A to 17C, when the driver turns on the high beam lighting switch, the head body 44 is rotationally driven to the “first position” and the vertically movable pin 32 is retracted (or shortened). ) As a result, the tip of the light emitting element 31 whose tip side is inclined toward the outer peripheral side is located at a position corresponding to the high / low light projecting hole 34. When light is emitted from the light emitting element in this state, a high beam is projected from the high / low light projecting hole 34 (FIG. 17A).

  Next, in the high beam projection state, when the driving vehicle turns on the low beam lighting switch, the up and down movable pin 32 moves forward (or extends), and the front end side of the light emitting element 31 moves from the outer peripheral side to the inner side. Tilt. Thereby, the optical axis of the light emitting element 31 is inclined downward. When light is emitted from the light emitting element in this state, a low beam is projected from the high / low light projecting hole 34 (FIG. 17B).

    Next, when both the high beam lighting switch and the low beam lighting switch are turned off, the head body 44 is rotationally driven to the “second position”, and the non-injection region on the front surface of the head body is driven. Is located at a position corresponding to the high / low light projection hole 34 (FIG. 17C).

  By this rotation of the head body, the front surface of the head body is automatically cleaned by the cleaning member (brush) 14. Further, the front face of the head body is cleaned by the cleaning liquid ejected from the cleaning member (spout port) 15 by the operation of the driver.

  Here, in the above description, an example of two-stage switching between high beam and low beam has been shown. However, in this embodiment, the inclination of the optical axis of the light emitting element 31 is set to advance the vertical movable pin 32. Although it can be continuously changed by the backward movement, when it is desired to change the inclination of the optical axis of the light emitting element 31 greatly (when δ is to be increased), the elliptical high / low throwing projection that is long in the vertical direction is used. The light hole 34 is preferable.

<Sixth Embodiment>
The sixth embodiment relates to a head device that uses a smaller head body than the fifth embodiment and tilts the head body in the vertical direction. FIG. 18 is a schematic cross-sectional view for explaining the main points.

  As shown in FIG. 18, the rear end portion of the headlight body 44 incorporating the light emitting element is connected to the drive unit 35. In this embodiment, the drive unit 35 tilts the front end side of the headlight body in the vertical direction with the rear end side as the base end, so that the optical axis of the light emitting element (not shown) is the high beam projection hole. 2 or a light beam projection hole 3 for a lobe.

  According to the present invention, a vehicle-mounted head device that does not increase air resistance, does not form a projection that damages the human body, does not reduce illuminance due to dirt, and does not restrict the degree of freedom in the appearance design of the front of the vehicle. Can be provided. Therefore, the present invention has high industrial applicability.
