JP5084040B2 - LIGHTING DEVICE FOR VEHICLE AND VEHICLE SEAT - Google Patents

Description

  The present invention relates to a vehicular illumination device that can illuminate a driver's feet and the like around a vehicular seat at night and the like, and a vehicular seat including the same.

  Conventionally, in vehicles such as automobiles, various lighting devices have been proposed for the purpose of improving the visibility of the driver's feet. For example, each pedal such as an accelerator pedal, a brake pedal, and a clutch pedal is used as a driver. For the purpose of easily recognizing, a pedal cover in which a light emitter such as an LED is embedded is mounted on each pedal.

  However, mounting a pedal cover including such a light emitter individually for each pedal increases the number of parts of the entire lighting device and complicates the structure. In general, the area (irradiation position, irradiation area, etc.) that the driver needs to illuminate differs between driving and getting on / off, so it is sufficient to simply illuminate the operating pedal as described above. It may be difficult to achieve foot lighting.

Therefore, for example, an illumination device as described in Patent Document 1 has been proposed. As shown in FIG. 11, the illumination device 100 includes a light source unit (not shown), and emission ports 102 and 103 provided below the instrument panel 101 on the driver's seat side to emit illumination light from the light source unit. An operation capable of switching the projection position between a first position where the pedals 104 to 106 project illumination light and a second position where the pedals 104 to 106 project illumination light behind the pedals 104 to 106. A knob 108 is provided.

FIG. 7 is an explanatory view showing an example, and FIG. 7 is a perspective view showing an operation of the vehicular lighting device according to the first embodiment of the present invention.

  1 and 2 show a vehicle seat S according to an embodiment of the present invention. The vehicle seat S is a fixed (or slidable) seat used for a driver's seat of a vehicle such as a passenger car (may be a passenger seat or a rear seat), and the vehicle lighting device 10 of the present invention is a seat portion. It is installed on the front side of the sheet S1. In addition, the code | symbol L in FIG. 1 shows the illumination area | region where the illumination light from a light source is projected by the vehicle illuminating device 10. FIG.

  This vehicular lighting device 10 illuminates the vicinity of a foot or the like, and is an opening portion of a space (hereinafter referred to as a storage chamber R) serving as a storage case for small items provided on the front foot side of the seat S1. The rotary plate door 20 having a function as a lid for opening and closing the opening is provided with a light source unit 30 and a hinge mechanism 40 between the rotary plate door 20 and the storage chamber R. (See FIG. 3). In the embodiment of the present invention, a case where a gap is formed between the rotary plate / door 20 and the bottom wall of the storage chamber R will be described. However, the space has substantially the same volume as the space forming the storage chamber R. The rotating plate door 20 may occupy the storage chamber R during the closing operation. Further, the rotary plate / door 20 may close the opening without any gap, or a slight gap between the opening and the opening (the small object accommodated in the accommodation chamber R is not separated from the accommodation chamber R). May be closed in a state where there is a gap.

  As shown in FIGS. 3 and 4, the rotary plate door 20 is centered on a rotation shaft 41, which will be described later, with respect to the storage chamber R in order to open and close the storage chamber R provided in the lower front part of the seat seat S <b> 1. It is installed so that rotation is possible. Further, the rotating plate door 20 is rotated, and specifically, opened and pulled out from the standing state shown in FIG.

  Further, as shown in FIG. 3, the rotating plate door 20 has a back cover so that the LED 31 that is a light source of the light source unit 30 to be described later can be easily removed and replaced with a new one when a failure occurs. 21 is detachably installed. The rotary plate / door 20 is provided with a lock hole 20A, which will be described later, and a knob 20B for an operator to hold and rotate the rotary plate / door 20.

  As shown in FIG. 1, the light source unit 30 of the present embodiment illuminates a front space near the foot of the seat S using a vehicle battery as a power source B (see FIG. 5). The part 30 is installed in a lamp house (not shown) provided inside the rotary plate door 20.

  The light source unit 30 includes an LED (light emitting diode) 31 that is a light source, a reflecting mirror 32 installed around the LED 31, and a transparent cover 33, and is lit by a micro switch 34. When the LED 31 is rotated and opened from the seat S1 by rotating the rotating plate / door 20, the micro switch 34 is turned on and turned on, and when the LED 31 is closed and stored, the micro switch 34 is turned off and turned off.

  In the present embodiment, the LED 31 is turned on / off by the micro switch 34 configured to be turned on / off in conjunction with the opening / closing operation of the rotating plate / door 20. You may comprise so that it may light in response to lighting operation, a small lamp, the lighting operation of a room light, or the opening operation of a vehicle door. With this configuration, an automatic lighting operation can be performed, which is convenient for nighttime with luggage.

  As shown in FIGS. 1 and 6, the LED 31 that is the light source of the present embodiment has a configuration in which a plurality (three in the present embodiment) of LEDs 31 are arranged in an array in the horizontal direction. In this case, in the present embodiment, the reflecting mirror 32 is installed around the LED 31 as the light source and a desired irradiation pattern is set. However, the present invention is not particularly limited to this. For example, as shown in FIGS. 6 (A) and 6 (B), in a state where they are connected to each other or spaced apart from each other by a predetermined distance, a light projecting lens such as a collimator lens 35 is installed on each optical axis of the LED 31 in parallel. Light may be formed.

  The hinge mechanism 40 can change the irradiation direction by changing the tilt angle of the rotary plate / door 20, and in this embodiment, as shown in FIG. 3, it rotates integrally with the rotary plate / door 20. The rotating shaft 41, a pressing member 42 that contacts a part of the outer peripheral surface of the rotating shaft 41, a compression spring 43 that biases the pressing member 42 with an elastic force, and the pressing member 42 are slidable. A substantially box-shaped guide member 44 whose one end face is opened to accommodate the compression spring 43, a pin 45 fixed from the rotating plate / door 20, and a rotational angle of the rotating plate / door 20. In order to restrict the range, an arc-shaped restricting groove 46 that is provided on the side wall of the storage chamber R and into which the pin 45 enters is provided.

  The rotating shaft 41 is made of an appropriate material having a large coefficient of friction and good wear resistance, for example, an appropriate resin material, and is formed in a substantially D-shaped cross section having a flat surface 41A in part. 20 and is rotatably supported by a bearing 47 provided on a side wall in the storage chamber R. That is, the rotating shaft 41 is contact-pressed by the pressing member 42 when the storage chamber R is closed by the rotating plate / door 20, that is, when the rotating plate / door 20 is upright as shown in FIG. The rotating plate door 20 is fixedly arranged so that the outer periphery of the portion to be formed becomes a flat surface 41A. The rotating shaft 41 is subjected to, for example, embossing or matte finishing in order to increase the holding force when the friction coefficient is increased and the rotating plate / door 20 is temporarily held at a desired inclination angle. You may do it.

  The pressing member 42 is also formed of an appropriate material having a large friction coefficient similar to that of the rotating shaft 41 and good wear resistance, for example, an appropriate resin material.

  Since the spring force of the compression spring 43 increases in accordance with the amount of compression, the rotary plate door 20 stands vertically (hereinafter referred to as a “closed state”. This state is also referred to as a “locked state”. The amount of compression is the smallest and the spring force is small, but the closed state (locked state) is maintained when the above-mentioned micro switch 34 enters the lock hole 20A. On the other hand, the rotating plate / door 20 and the rotating shaft 41 integral with the rotating plate / door 20 are rotated by a predetermined angle or more and tilted by a predetermined angle or more toward the horizontal (horizontal) direction (hereinafter referred to as “open state”). Then, the rotating shaft 41 comes out of contact (locked) with the flat surface 41, and the pressing member 42 comes into contact with the circumferential surface, so that it moves backward compared to the closed state (see FIG. 4). As a result, the compression spring 43 is compressed, and the inclination angle of the rotating shaft 41 at that time can be maintained with an increasing spring force.

  The pin 45 is for limiting the rotation range when the rotary plate / door 20 is rotated from the closed state, in other words, for limiting the inclination angle, and the rotary plate / door 20 is rotated. Then, the inside of the regulation groove 46 provided on the side wall of the storage chamber R moves.

  Therefore, according to the present embodiment, for example, when the operator grasps and rotates the knob 20B from the state of FIG. 3, the rotating plate door 20 is released from the closed state as shown in FIG. Turns on and LED 31 lights up. When the operator grips the knob 20B and closes the rotary plate door 20, the LED is turned off. Thereby, the operation of turning on and off the LED can be easily performed, and the usability is good. A switch for turning on and off the LED can be made large, and a switch for a lighting device having a clean appearance can be realized.

  Then, by rotating the rotating plate / door 20 in an open state with a desired inclination angle within the range of angles allowed by the restriction groove 46, the illumination area is continuously changed steplessly as shown in FIG. Can be made. That is, as the rotation angle is increased (the inclination angle is decreased), the illumination area can be gradually brought closer to the feet. Therefore, for example, when the driver searches for a fallen object or the like, the illumination area can be changed freely and easily.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals to avoid redundant description. FIG. 8 is a block diagram showing a vehicular illumination device according to a second embodiment of the present invention, and FIG. 9 is an explanatory view showing a rotating state of a rotating plate / door provided with the vehicular illumination device. is there.

  This embodiment is different from the first embodiment in that a multi-step tilt operation shown in FIGS. 8 and 9 is used instead of the hinge mechanism 40 having a substantially D-shaped rotation shaft 41 and capable of a stepless continuous tilt operation. The hinge mechanism 50 which performs is provided. In these drawings, the illuminating device 10 having the light source unit is omitted because it has the same configuration as that of the first embodiment.

  8 and 9, the hinge mechanism 50 is provided with a multistage lock member 51 formed on the storage chamber R side and a positive cam groove 52A between the lock member 51 and integrally formed on the storage chamber R side. The eccentric cam 52 and the rotating plate / door 20 are rotated counterclockwise along the three locking grooves 51A and the positive cam groove 52A of the locking member 51 by opening / closing the rotating plate / door 20. With respect to the engaging pin 53 fixed, the rotating shaft 54 fixed to the rotary plate door 20 and rotatably supported by a bearing 59 provided on the side wall of the storage chamber R, and the engaging pin 53 A compression spring 55 provided on the rotary plate door 20 that gives a spring force in a direction approaching the rotary shaft 54, and a rotary plate that is fixed to the end of the compression spring 55 and abuts on the engagement pin 53. Pushing provided on the door 20 The guide groove 57 provided in the rotating plate door 20 that restricts the movement of the material 56, the engaging pin 53, the compression spring 55, and the pressing member 56, the rotating shaft 54, and the rotating plate In order to apply a counterclockwise spring force to the door 20, a torsion spring 58 having a distal end fixed to the rotation shaft 54 and a proximal end fixed to the storage chamber R side is provided.

  The three lock grooves 51A of the lock member 51 have a unique shape that constitutes a one-way structure having a ratchet mechanism in one direction so that the engagement pin 53 only allows counterclockwise rotation. And prevents it from turning counterclockwise.

  As shown in FIG. 8, the compression spring 55 of the present embodiment prevents the torsion spring 58 from rotating when the torsion spring 58 is in a closed state so that the rotating plate door 20 is not released from the closed state by the rotational force of the torsion spring 58. It has an elastic force that pushes the engaging pin 53 toward the rotating shaft 54 with a larger spring force against the force.

  When the positive cam groove 52A is further opened from the state shown in FIG. 9 and the rotary plate door 20 is inclined to the maximum open state, the engagement pin 53 falls and thereafter the compression spring 55 resists the rotational force of the torsion spring 58. The distance (radius) between the rotary shaft 54 and the rotating shaft 54 is gradually reduced so that the push-out force returns to the closed position (initial position) shown in FIG.

  Therefore, according to the present embodiment, when the operator grasps the knob 20B and opens and pulls out the rotating plate door 20, the rotating plate door 20 is opened from the closed state shown in FIG. 8 as shown in FIG. Then, the micro switch is turned on and the LED is lit. That is, when the rotary plate door 20 is manually opened and pulled out with an opening force that exceeds the pushing force of the compression spring 55, the engagement pin 53 is in the closed position (initial position), that is, the positive cam groove. It escapes from the rightmost end portion of 52A (that is, the position immediately after the neutral point is exceeded), and rotates counterclockwise along the outer periphery of the lock member 51.

  Then, due to the pushing force of the compression spring 55, the engagement pin 53 is fitted into the first lock groove 51A. Since the rotational force of the torsion spring 58 is set so as not to exceed the pushing force of the compression spring 55, the locking state of the engagement pin 53 in the lock groove 51A is not changed unless the operator further operates in the opening direction. Maintained. Further, the latching function of the lock groove 51 </ b> A prevents the engagement pin 53 from escaping due to the pushing force of the compression spring 55 and returning to the closing direction. As a result, the rotating plate door 20 is kept locked at the first inclination angle. Therefore, the illumination light from the LED (not shown) is projected and illuminated toward an area slightly away from the foot of the seat S1.

  Further, when the operator grasps the knob 20B and opens the rotary plate / door 20, the engaging pin 53 is inserted into the second lock groove 51A. As a result, the rotating plate door 20 is maintained in the locked state at the second inclination angle that is looser than the first inclination angle. Therefore, the illumination light from the LED (not shown) is projected toward the area closer to the foot of the seat S1 than the first illumination area.

  Similarly, when the rotating plate door 20 is further opened, the engagement pin 53 is inserted into the third lock groove 51A, and the illumination light from the LED (not shown) is seated more than the second illumination area. The light is projected toward an area closer to the foot of the partial sheet S1.

  Further, when the rotary plate door 20 is further opened, the engaging pin 53 falls into the positive cam groove 52A and returns to the initial position shown in FIG. 8 by the spring force of the compression spring 55 as described above. Therefore, the rotary plate door 20 also automatically returns to the closed state shown in FIG. As a result, the micro switch 34 returns from the on state to the off state, and the LED is automatically turned off.

Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals to avoid redundant description. FIG. 10 is a perspective view illustrating an illumination state in an automobile having a seat according to the third embodiment of the present invention.

  The seat of this embodiment uses a rotary seat S ′ instead of the fixed (or slidable) seat used in the first embodiment, and a vehicle lighting device 10 is installed on the seat. It is.

  Therefore, according to the present embodiment, for example, when the rotary seat S ′ is rotated and the rotary plate / door is pulled out when getting on and off, the illumination light from the vehicle illumination device 10 is projected in the forward direction of the seat S ′. Can shine. That is, it is possible to project illumination light from the doorway of the vehicle with the door open toward the outside. Accordingly, the feet of passengers waiting outside the vehicle near the door can be brightly illuminated, which is convenient at night.

  Further, in this embodiment, the light source is not only turned on by a drawing operation of the rotating plate / door not shown, but for example, the door is opened and the sheet S ′ is rotated and lowered (the sheet S ′ is pulled out from the door). In other words, the illumination light can be turned on without pulling out the rotating plate door (outward from the door). In that case, unlike the case where the rotating plate / door is pulled out and tilted downward, the rotating plate / door remains upright, so that the outside of the vehicle above the lower direction such as the road surface is lowered. It becomes possible.
