Connected to the control means for inputting the driving information of the vehicle, and when the vehicle driving information is determined by the control means to be in a state of reversing the vehicle, the actuator is driven to The lamp body is developed to a position protruding outside from the position housed in the recess, and the lamp is turned on to irradiate the rear field of view. , Characterized by.

  According to a fourth aspect of the present invention, there is provided a vehicle rear lighting apparatus according to the third aspect, wherein the control means is provided with a lamp switch for turning on / off the lamp by an ON / OFF operation, or a headlamp. A lamp switch that is turned ON / OFF in conjunction with the headlight switch that turns off the light is electrically connected, and it is determined by the control means that the vehicle driving information is in a state of moving the vehicle backward, and the lamp switch is turned ON. The lamp is lit on condition that it is operated.

  According to a fifth aspect of the present invention, there is provided the vehicle rear lighting device according to the third or fourth aspect, wherein an imaging means for photographing a rear view of the vehicle is housed in the vicinity of the lamp of the lamp body, and the vehicle On the condition that the driving information is determined by the control means to be in a state of reversing the vehicle, an image of the rear view of the vehicle by the imaging means that operates simultaneously with the lighting of the lamp is displayed on the monitor device. It is characterized by that.

  A sixth aspect of the present invention relates to the vehicle rear lighting device according to any one of the first to fifth aspects, wherein the lamp body is rotated about an axis in the vehicle width direction in the recess of the upper frame. And the outer surface of the lamp body is substantially the same continuous surface as the outer surface of the upper frame when the lamp body is in a position accommodated in the recess. Features.

  According to the first aspect of the present invention, the recess is formed in the upper frame of the rear door provided on the rear surface of the one-box type vehicle, and the lamp body having the lamp is removably attached to the recess. An actuator provided between the recess and the lamp body, for example, driven by a driving force generated by an electromagnetic solenoid, an electric motor or the like manually operates an operation switch provided on an instrument panel or the like around the driver seat, for example. As a result, the lamp body expands to a position protruding outside from the position housed in the recess, and the lamp is turned on to irradiate the rear view area from the upper frame. Further, by manually operating the operation switch in this state, the lamp body protruding outward can be stored in the recess by driving the actuator.

  For this reason, even in a so-called one-box type vehicle such as a van type passenger car, a wagon car, etc., which is considered to have poor visibility in the rear view, for example, when performing reverse running on a dark road at night, By turning on the lamp with one manual operation of the operation switch, it is illuminated and illuminated so that the condition of the traveling road surface in the reverse direction can be easily seen, so reverse traveling can be realized safely, and other than at night If you want to use a lamp even in a garage, for example in a multilevel parking lot, etc., you can irradiate the rear view in the garage at any time by manually operating the operation switch as needed. It is convenient because you can park safely and open / close the rear door smoothly. In addition, when it is not necessary to turn on the lamp, the lamp body remains housed in the recess, so that various effects can be achieved that the vehicle rear lighting device can be prevented from being tampered with and damaged.

According to the second aspect of the present invention, the image pickup means, for example, a CCD camera or the like for taking an image of the rear field of view of the vehicle is provided at a position close to the lamp of the lamp body having the lamp. Since it is operated in conjunction with the manual operation of the switch or by manual operation of the imaging switch provided separately from the above operation switch, it can be operated when the lamp body projects outward (when deployed). When the switch is turned on and the lamp is turned on, the imaging means captures the rear field of view, or by operating the imaging switch (camera switch) provided in the electric circuit, so that the imaging means is arbitrarily selected only when necessary. The photographed image is also displayed, and the photographed image is displayed on a monitor device provided around the driver's seat.
For this reason, for example, when the vehicle is driven backward at night, not only the backward field of view is illuminated brightly with a lamp, but also the road surface in the backward visual field region is photographed by the imaging means and the image is displayed on the monitor device. Therefore, the driver can operate while visually recognizing the rear view, not only by actually viewing the rear view, but also by looking at the screen displayed on the monitor device. The effect which becomes.

  According to the invention of claim 3, a rear door provided on the rear surface of the one-box type vehicle so as to be opened and closed, a recess formed in the upper frame of the rear vehicle, provided in the recess, A lamp body having a lamp that irradiates the lamp body, an actuator that is provided between the lamp body and the recess, and that operates the lamp body to be freely movable, and an electric circuit that turns on and off the lamp, Control means for inputting driving information, and when the vehicle driving information is determined by the control means to be in a state of reversing the vehicle, the actuator is driven so that the lamp body is In this case, the lamp is turned on to illuminate the rear field of view. By operating the lever in the reverse direction, the operation signal is input to the control means as vehicle driving information in a state of reversing the vehicle, whereby the actuator is driven by the electrical signal output from the control means, and the lamp body Is automatically actuated from the stowed position to the unfolded position that protrudes outward, and the lamp is also automatically lit to illuminate the road surface on which the vehicle is going to run backward. Not only will you be able to see the road surface well, it will notify the people around you in the direction of retreating that the vehicle is retreating and approaching, and it will be possible to realize safe driving at the time of reversing .

According to a fourth aspect of the present invention, the control means is electrically connected to a lamp switch that controls turning on / off of the lamp by an ON / OFF operation, and the vehicle driving information is in a state in which the vehicle is moved backward by the control means. Since the lamp is lit on the condition that the lamp switch is turned on, the lamp switch is turned on manually by the driver's judgment even when the vehicle is driven backward. By operating, the lamp body is unfolded and the lamp is lit. Conversely, when the surroundings are bright, such as during the daytime, the lamp body should not be unfolded by not operating the lamp switch. In addition, unnecessary power loss is suppressed by preventing the lamp from being turned on carelessly. Even after the lamp switch is turned on once (during reverse operation), the lamp switch can be turned off in the middle to turn off the lit lamp in a timely manner and store the lamp body. The passenger (mainly the driver) can selectively turn the lamp on and off, which has a useful advantage.
Further, the lamp switch may be configured as a lamp switch that is turned on and off in conjunction with the headlamp switch that controls turning on and off of the headlamp (vehicle width lamp). As a result, when the headlamp is turned on, the surroundings are often in a dark state. Therefore, in such a case, when the vehicle is moved backward, the rear illumination device is also turned on at the same time so that the vehicle can be moved backward safely.

  According to the fifth aspect of the present invention, the imaging means for photographing the rear view of the vehicle is housed at a position close to the lamp of the lamp body, and the vehicle driving information is in a state where the vehicle is moved backward by the control means. Since the image of the vehicle rear view by the image pickup means that operates simultaneously with the lighting of the lamp is displayed on the monitor device on the condition that it is determined that the lamp body is When the surrounding environment is dark, such as at night, the rear field of view illuminated by the lamp is captured by the imaging means, for example, on the monitor panel installed on the instrument panel of the cab, etc. Projected. For this reason, the driver can not only directly view the rear field of view, but also can perform a driving operation while looking at the image displayed on the monitor device, and has the effect of being able to drive backward more safely.

  According to the invention described in claim 6, when the lamp body is provided in the recess of the upper frame so as to rotate about the axis in the vehicle width direction, and the lamp body is in a position accommodated in the recess. Since the outer surface of the lamp body is substantially the same continuous surface as the outer surface of the upper frame, the lamp body can be rotated in a recess of the upper frame with a simple structure so that the lamp unit can be moved freely. When the lamp protrudes from the recessed portion to the storage position, the outer surface of the lamp body is substantially continuous with the outer surface of the upper frame of the rear door. It has the effect of preventing theft and accidents from being removed.

  The best mode for carrying out the present invention will be described in detail with reference to the drawings.

  A vehicle rear lighting apparatus according to a first embodiment corresponding to claims 1, 2 and 7 will be described with reference to FIGS. That is, FIG. 1 is a schematic external perspective view showing the position of a rear lighting device provided behind a one-box type vehicle, and FIGS. 2 and 3 are longitudinal directions of a rear door 20 (hereinafter referred to as “tailgate”). FIG. 2 is a longitudinal sectional view for explaining an outline of the assembled state of the vehicle rear lighting device, cut in a longitudinal section along the central axis, and a lamp unit body 10 which is a main component of the vehicle rear lighting device is a one-box type vehicle rear door 20.

  The upper frame 21 located at the upper edge of the rear window glass 24 is provided with an opening edge (flange) 25 that is opened to receive the vehicle rear lighting device 10, and thereby the lamp unit body 10 of the vehicle rear lighting device is arranged. A recess 26 is formed for storage.

As shown in FIG. 5, the lamp body 11 has a waterproof structure that prevents the intrusion of rainwater, and the bottom plate 12 a of the casing 12 is attached with the lamp 13 and a CCD camera 50 that is an imaging means in the vicinity of the lamp 13. . The lamp 13 and the CCD camera 50 are electrically connected to an electric circuit 40 shown in FIG. For example, the harness 14 for the lamp 13 (see FIGS. 6 and 7) is connected to the lamp 13 through the waterproof grommet 14 a. Similarly, a harness (not shown) for the CCD camera 50 is also penetrated by a waterproof grommet and connected to the electric circuit 40.
The lamp body 11 has pins 11a protruding on both the left and right sides of the casing 12, and the pins 11a have a rectangular frame portion 16a and open toward the rear of the vehicle. It is pivotally supported so as to rotate.

  Also, an actuator 17 is provided between the side wall of the casing 12 and the storage box 16 so that the front and rear ends thereof are rotatably supported. The actuator 17 is electrically connected to the electric circuit 40, and when the electromagnetic solenoid is excited or demagnetized, the rod 17a is expanded and contracted, whereby the lamp body 11 is moved from the housed state shown in FIG. As shown in FIG. 4, the motor is driven to rotate (deploy) counterclockwise.

  Further, a return spring 18 is stretched between the casing 12 and the storage box 16, and the lamp body 11 is always spring-loaded so as to be biased to a position where it is stored in the storage box 16 as shown in FIG. 6. It is energized.

  Thus, the frame portion 16a is joined by the flange portion formed in the opening of the storage box 16, and the lamp body 11 is stored in the storage box 16 so as to be rotatable via the pin 11a, and the lamp body 11 and the storage box 16 are stored. An integral lamp unit body 10 having a waterproof structure in which an actuator 17 and a return spring 18 are attached between the two and a waterproof structure such that a grommet or a soft synthetic resin material is appropriately coated on a joining portion of a member or the like. That is, the main part of the vehicle rear lighting device is formed. In the lamp unit body 10, a recess 10a is formed as a space that allows the lamp body 11 to rotate around the pin 11a.

  A method of attaching the lamp unit body 10 in which the lamp body 11 is integrated into the storage box 16 to the recess 26 of the upper frame 21 will be described. 2 and 3, the flange 10b of the lamp unit body 10 is aligned with the opening edge 25 of the upper frame 21, and the bolt 10c attached to the back of the storage box 16 is passed through the bolt hole 26b of the recess 26, The lamp unit body 10 is positioned and fixed in the recess 26 simply by tightening with the nut 26c. In this case, of course, an appropriate waterproofing member (not shown) such as a weather strip is interposed between the opening edge 25 and the flange 10b of the lamp unit body 10, and rainwater is inadvertently disposed in the internal space of the upper frame 21. Prevents intrusion. In this way, when the lamp unit body 10 is attached to the recess 26 formed in the central portion of the upper frame 21, as shown in FIGS. 3 and 4, the outer surface of the rear surface of the lamp body 11 is the tailgate 20 or the upper part. It is formed so as to exhibit a surface continuous with the outer surface of the frame 21.

  Next, the configuration of the electric circuit 40 of the vehicle rear lighting device will be described with reference to FIG. The electric circuit 40 is electrically connected to a battery 41, an operation switch 42 as a lamp switch, an actuator 17, a lamp 13, a CCD camera 50, and a monitor device 51 that displays an image taken by the CCD camera 50. The operation switch 42 can be turned on and off by manual operation. When the operation switch 42 is turned on, the current of the battery 41 is supplied to the lamp 13, the actuator 17, the CCD camera 50, and the monitor device 51. Yes.

  The operation of the first embodiment will be described. First, as shown in FIG. 1, when the vehicle is driven backward at night, the operation switch 42 is turned ON by manual operation. Then, the current of the battery 41 is energized to the lamp 13, the actuator 17 and the CCD camera 50. In the actuator 17, an electromagnetic solenoid (not shown) is excited, and the rod 17a extends. Then, as shown in FIG. 6, the lamp body 11 housed in the recess 10 a of the housing box 16 rotates the pin 11 a at the center of rotation while resisting the spring force of the return spring 18 as indicated by the arrow in FIG. 7. As shown in FIG.

  Thus, from the lamp body 11 deployed at the maximum opening degree, the light of the lit lamp 13 irradiates the rear view and illuminates the rear traveling road surface brightly. In addition, the CCD camera 50 captures the brightly illuminated road surface, and the captured image is displayed on the monitor device 51. In this state, the driver can visually check the rear view and see the screen of the monitor device 51, and can check the traveling road surface in the backward direction that is brightly illuminated. Will be able to do.

  On the other hand, when the reverse operation is finished, the operation switch 42 is turned OFF to interrupt the current from the battery 41. As a result, the operation of the lamp 13, the actuator 17, the CCD camera 50, and the monitor device 51 is stopped, and the lamp body 11 is housed in the recess 10a and closes the frame portion 16a, as shown in FIG. .

  Of course, even when it is not at night or when the vehicle does not run backward, by arbitrarily turning on the operation switch 42, the lamp body 11 is unfolded, the lamp 13 is turned on, and the CCD camera 51 is operated. Since the situation around the tailgate 20 can be displayed on the monitor screen or brightened, it is also possible to facilitate loading and unloading of luggage when the vehicle is stopped.

  According to the first embodiment, when the vehicle is traveling backward on a dark road at night, the state of the traveling road surface in the backward direction is changed by turning on the lamp 13 by one manual operation of the operation switch 42. Irradiating and illuminating so that it can be easily seen, it is possible to safely implement reverse travel. In addition, since an image captured by the CCD camera 50 is displayed on the monitor device 51, the rear view can be confirmed more reliably by looking at the monitor device 51. Furthermore, even in the case other than at night, for example, in a garage, a multi-story parking lot, etc., by manually operating the operation switch 42 as necessary, the lamp 13 whose rear view in the garage is lit at any time. And the image display by the monitor device 51 by the CCD camera 50 allow smooth parking in the garage or smooth loading and unloading work by opening the rear door. Furthermore, when it is not necessary to turn on the lamp, the lamp body 11 remains housed in the recess 10a, so that it is possible to avoid damage caused by mischief of the vehicle rear lighting device. When the vehicle rear lighting device is not used, the lamp body 11 is housed in the recess 10a. At this time, the outer surface of the lamp body 11 is continuous with the outer surface of the tailgate 20 and the upper frame 21 thereof. Since the surface is formed, the running resistance can be suppressed, and the appearance can be improved by the smart appearance.

In the first embodiment, the CCD camera 50 is configured to be turned ON / OFF in conjunction with the ON / OFF operation of the operation switch 42. However, as in the modification shown in FIG. A dedicated camera switch 52 for turning the CCD camera 50 on and off may be provided. According to such a modification, when it is not necessary to monitor the image captured by the CCD camera, the camera switch 52 may be turned off manually.
In the first embodiment, the CCD camera 50 is provided. Needless to say, however, the CCD camera 50 may be omitted.

  Next, a second embodiment corresponding to the third and subsequent claims will be described. That is, the second embodiment is different from the first embodiment in that the lamp 13 of the lamp body 11 and the CCD camera 50 are manually controlled by the operation switch 42 in the first embodiment. The second embodiment is different from the first embodiment in that these controls can be automatically performed by a control means to be described later, and the other configurations are substantially the same. In the following description, only differences in configuration will be described, and the same reference numerals are used for the same members, and detailed descriptions thereof will be omitted.

As shown in FIG. 10, the electric circuit 40 according to the second embodiment is provided with a control unit 60 that is a control unit that is electrically connected to the battery 41. The control unit 60 includes
An ignition signal output from the ignition sensor to indicate whether the engine is in an operating state, a shift lever signal output from the shift position sensor to indicate whether the shift position of the transmission is in the reverse position (reverse), and a parking sensor Vehicle driving information such as a parking signal indicating whether or not the parking brake is being operated is input as a control signal. Further, an output signal based on the control signal is output from the control unit 60 to a control target device such as a lamp (lamp device) 13 and an actuator 17 so that the control target device is controlled by the output signal. Is formed.

  The operation of the vehicle rear lighting device in the second embodiment will be described based on the control flowchart of FIG. In step S1, whether or not the engine is in a driving state is checked based on the presence or absence of an ignition signal. If it is determined that the vehicle is in a state where the vehicle can run, whether or not the parking brake is operating in step S2. Whether there is a parking signal is determined. If it is determined that the parking brake is released and the vehicle is in a movable state, the process proceeds to step S3. In step S3, it is determined based on the shift lever signal whether or not the shift operation is performed to the reverse position where the reverse travel is possible. In step S3, a signal for lighting the lamp 13 is output from the control unit 60, and the lamp is lit (step S4). At the same time, a drive signal is output from the control unit 60 to the actuator 17, the rod 17a extends, and the lamp body 11 rotates and expands (see step S5, FIG. 7). In this way, the lamp 13 in the lamp body 11 that is automatically opened can automatically illuminate and illuminate the road surface in the reverse direction to be reversely operated, and the driver can perform reverse operation at night or the like. It will be safe and reliable.

Further, in step S6, when the control unit 60 that has detected the shift lever signal is in a neutral position other than reverse and a forward shift position, or a shift position (forward position) other than the reverse and neutral positions. If you decide,
The lamp 13 is automatically turned off (step S7), and the lamp body 11 is housed in the recess 10a and closed (step S8). If NO is determined in steps S1, S2, and S3, the process proceeds to step S9, the actuator 17 is not driven, and the lamp 13 is not lit.

As described above, according to the second embodiment, when the driver tries to perform the reverse operation, the lamp body 11 is automatically opened by the control unit 60 and the lamp 13 is also turned on, so the vehicle moves backward. The road surface is illuminated, the visibility can be improved, and the reverse operation can be performed safely. Further, when the reverse operation is stopped, the lamp body 11 is automatically closed and the lamp 13 is turned off, which is convenient.
In the second embodiment, a modified example in which the CCD camera 50 is attached can be used, whereby the monitor device 51 can display the rear field of view. In this case, the monitor screen is displayed. As a result, the rear view can be confirmed, and the safety level is increased accordingly.
In FIG. 11, step S4 and step S5, step S7 and step S8 may be reversed in order.

  Next, a third embodiment shown in FIGS. 12 and 13 will be described. In the second embodiment, when the reverse operation is performed, the lamp body 11 is always opened and the lamp 13 is turned on. However, in the third embodiment, even if the reverse operation is performed, The driver can selectively turn the lamp 13 on and off. That is, the third embodiment is different from the second embodiment in that the control unit 60 is provided with a lamp switch (not shown) that can turn on / off the lamp 13 by ON / OFF operation. The difference is that a lamp control signal is inputted, and an output signal as a result controlled by these controlled input signals can be outputted to the CCD camera 50 and the monitor device 51. The lamp switch has the same function as the operation switch 42 in the first embodiment, and is a manual operation switch that allows the driver to selectively turn on / off the lamp 13 at his / her own discretion. That is. When the lamp 13 is turned on, the CCD camera 50 is also ready for photographing in conjunction with it.

  The operation in the vehicle rear lighting device of the third embodiment will be described with reference to FIG. That is, the difference from the second embodiment is that step S3a is added between step S3 and step S4 in FIG. 11, step S4a is added between step S4 and step S5, and step S6 is changed to step S5a. Step S7a is added between step S6 and step S7, and other steps S are the same as those in FIG.

  For this reason, according to the third embodiment, even when the vehicle proceeds backward from step S1 to step S3 and the vehicle is driven backward, when the lamp switch is turned on manually in step S3a, the lamp control is performed. The control unit 60 receives the signal and determines that the lamp switch is ON. As a result, the lamp 13 is turned on (step S4), the CCD camera 50 is operated (step S4a), and the lamp body 11 is developed (step S5). For this reason, the lamp can be turned on and the CCD camera 50 can be operated only when the vehicle is in a state of being driven backwards day and night and the lamp switch is turned on. In other words, in the case of reverse operation in a situation where the surroundings are bright as in the daytime, it is not necessary to illuminate the rear view with the lamp, so the lamp switch is not turned on. As a result, the actuator 17 remains closed at the storage position (step S9), and the lamp 13 is not turned on, so that unnecessary power consumption of the battery can be suppressed. Even after the lamp switch is once turned on, the lamp switch is turned off in the middle (step S5a) to turn off the lit lamp in a timely manner (step S7), and the operation of the CCD camera 50 is also stopped. (S7a). Thus, the driver can selectively control the operation of the lamp 13 and the CCD camera 50, which is convenient.

As described above, the present invention has been described based on each embodiment and modification. However, the specific configuration is not limited to these embodiment and modification, and the scope of the present invention is not deviated. Even if there is a design change, it is included in the present invention.
That is, although the operation switch 42 as the lamp switch in each of the above embodiments has been described as a manual switch that can be arbitrarily turned on and off, instead of this, the headlamp that controls turning on and off of the headlamp is described. It is also possible to configure a lamp switch that is turned on and off in conjunction with the switch. As a result, when the headlamp is turned on, it is turned on because the surrounding conditions are dark. Therefore, if the rear illumination lamp 13 is turned on at the same time when the headlamp is turned on, the backward movement is performed. You can do it safely.

In addition, the CCD camera 50 is used as the imaging unit used in the first embodiment, its modification, the second embodiment, and the third embodiment. A normal video camera may be used.

  In the control flow diagram of FIG. 13, the order of step S4, step S4a, and step S5 may be replaced with step S as appropriate. Similarly, the order of step S7, step S7a, and step S8 may be changed as appropriate.

  In addition, the actuator 17 in each embodiment and each modification uses an electromagnetic solenoid, but instead, a crank arm is provided on the rotating shaft of the electric motor, and this crank arm can be rotated freely. A mode in which the lamp body 11 is rotated around the pin 11a using a coupled crank lever mechanism may be employed.
