Description

The present invention relates to a vehicular panel for transmitting information to the outside of a vehicle, and more particularly to a vehicular light emitting panel that can clearly display information by including a light emitting element.

Conventionally, as a means for transmitting information to the outside of the vehicle, there is no choice but to use existing equipment such as headlamps, winker lamps, hazard lamps, or horns, and by lighting or ringing these for a short time, They expressed their appreciation and requests for other vehicles.
However, recently, due to the increase in traffic volume and the development of road network, the frequency of traffic congestion, lane change, overtaking, etc. is increasing, and there is a tendency for the drivers to be bothered frequently. Under such circumstances, the lighting of short lamps as described above is clearly insufficient to clearly convey one's intention to the other party.
Therefore, in recent years, in order to clearly transmit more information to the outside of the vehicle, a technique of display means capable of displaying characters and the like has been developed, and some ideas have been already disclosed in relation to this. ..

However, in the device disclosed in Patent Document 1, a large number of light emitting elements are attached to the surface of the substrate by using, for example, an adhesive to form a character display, so that only one type of information can be operated at a time. I can't reach my hands. Therefore, the cost-effectiveness is good when there is only one scene to transmit the character display, etc., but if you try to prepare multiple types of character display to support various scenes, the cost will increase. There is a risk.
Further, since the vehicular sign display device according to the present invention is specifically attached to an arbitrary position on the outer surface of the vehicle by using a suction plate made of synthetic resin, it is possible to prevent rain, snowfall, wind pressure during traveling, Vibration may cause it to fall onto the road and be lost.

Next, in the device disclosed in Patent Document 2, specifically, since the vehicle thank-you display device is attached to the inner surface of the rear window using two suction suspension bodies, the device according to Patent Document 1 is disclosed. Like, it is unlikely to fall on the road and be lost. However, since the thanks display is swingably attached to the inner surface of the rear window of the vehicle via the suction suspension body, the thanks display swings strongly when the vehicle body vibrates strongly on bad roads. As a result, it may drop or collide with the rear window, resulting in damage to the thank-you display.

The present invention has been made in response to such a conventional situation, and is capable of reliably transmitting information to the outside of the vehicle, and further, it is possible to enhance the cost-effectiveness by limiting the function. It is also an object of the present invention to provide a vehicular light-emitting panel that can appropriately realize a driver's desired usage and prevent loss or damage by making it possible to select a configuration that is multifunctional and easy to use. ..

In order to achieve the above-mentioned object, the first invention comprises a panel installed inside a vehicle for transmitting information to the outside of the vehicle, the panel being provided on a flat base body and the base body. A light-emitting element that causes a light-emitting region to appear on the surface of the light-emitting device is provided, and the surface is characterized in that inscriptions representing information are formed.
In devising such a structure, as a combination of the base and the light emitting element, for example, a light guide plate or an electronic bulletin board can be considered. In addition to the LED element, an organic EL element is used as the light emitting element.

Further, in the first invention, the light emitting area that appears on the surface of the panel may be written, or the non-light emitting area other than the light emitting area on the surface may be written.
Therefore, for example, when a light guide plate is used, a light emitting region appears on the entire surface thereof. Therefore, when a non-light emitting region is formed on this light emitting region, this non-light emitting region is described. On the other hand, when the electronic bulletin board is used, the light emitting area or the non-light emitting area appearing on this surface is described. Further, the notation can be changed to a plurality of types, and may be limited to one type and not changed.
In the invention of the above configuration, since the notation is visually recognized by utilizing at least the light emitting area, the notation is clearly recognized from the outside of the vehicle regardless of day and night or the weather.
Further, by selecting the combination of the base and the light emitting element and changing or not changing the notation, the vehicle light emitting panel having various configurations is manufactured.

Next, in the second invention, in the first invention, the panel is a light guide plate in which the light emitting element is disposed on one end surface of the base, and the notation is a non-light emitting element that shields the light emitted by the light emitting element. It is a characteristic material.
In the invention of such a configuration, as the notation of the non-luminous material, for example, a seal body attached to the outer surface of the diffusion surface of the light guide plate, a character or a figure by the paint applied to the outer surface can be considered. ..
In the device having the above-described configuration, in addition to the operation of the first device, the light emitted from the light emitting element is blocked by the inscription, and the inscription can be visually recognized. Moreover, although the notation by the seal body and the paint cannot be changed in real time, for example, by replacing the seal body of a plurality of types in which characters representing different information are written or repainting the paint, Can convey information.

Subsequently, a third invention is characterized in that, in the first, the panel is an electronic bulletin board in which a plurality of light emitting elements are arranged in a matrix on a base.
In the invention of such a configuration, the notation is formed by each position where a plurality of light emitting elements emit light and each emission intensity level. Depending on its configuration, the electronic bulletin board may display only one type of notation registered in advance unchangeable, or may change and display any one of a plurality of types of notation by a switch operation. Therefore, it becomes possible to select different usage modes with one unit.
In the device having the above-described configuration, in addition to the operation of the first device, the notation can be visually recognized by controlling the light emitting position of the light emitting element. When the notation can be changed in real time, most necessary information can be transmitted at an appropriate timing.

Furthermore, a fourth aspect of the present invention is any one of the first to third aspects of the present invention, further comprising mounting means for holding the panel in a non-pivotable manner, and the mounting means is fixed to a position other than the surface of the base body. At the same time, it is characterized in that it is attached to the inner surface of the window of the vehicle or the inner wall surface of the vehicle close to this inner surface.
In the invention of such a structure, the attachment means for holding the panel in a non-pivotable manner means that the panel is placed at a fixed position with respect to the window so that the panel does not sway even by vibration during traveling. It is a fixed member.
Therefore, as the attachment means, for example, by fixing the base body by suction or adhesive so as to be in contact with the inner surface of the window, it is fixed to the suction member or the adhesive member that holds the base body, the frame portion of the window, or the inner wall surface of the vehicle. A combination of a frame body and a fastener provided on the frame body and supporting the base body is conceivable.
In the device having such a structure, in addition to the operation of the device described in any one of the first to third aspects, the panel is fixed at a fixed position with respect to the window through the attaching means, so that the panel is strong. Oscillation is prevented. Therefore, the panel itself is prevented from inducing the drop or the like.

According to the first invention, the notation is clearly recognized from the outside of the vehicle regardless of day or night or the weather, so that the information can be reliably transmitted to the outside of the vehicle. In addition, by selecting the combination of the base and the light-emitting element, or by making the notation changeable or not changeable, the structure that can limit the function and increase the cost-effectiveness, or make it multi-functional and easy to use Since the configuration to be obtained can be selected, the driver's desired usage can be appropriately realized.

According to the second invention, in addition to the effect of the first invention, the notation can be visually recognized only by causing the light emitting element to emit light, so that the configuration is relatively simple and the operation during driving is easy. Further, when it is sufficient to transmit limited information, there is an advantage that it can be manufactured at low cost.

According to the third invention, in addition to the effect of the first or second invention, the configuration of the electronic bulletin board can be changed, so that various information can be transmitted by one device.
Further, in the case where the notation can be changed in real time, the most necessary information can be transmitted at an appropriate timing, so that, for example, the effect of alleviating dissatisfaction with other vehicles can be exerted, and the occurrence of flapping operation can be suppressed.

According to the fourth invention, in addition to the effect of any one of the first to third inventions, it is possible to prevent the panel from swinging strongly or inducing its fall, etc. In addition to being able to transmit information to the driver in a stable manner, the product life of the original length can be exhibited.

It is an arrow sectional view at the time of seeing, and (c) is a B direction arrow view in (a). (A) is a front view of a vehicular light emitting panel according to a second modification of the first embodiment, and (b) is a usage state diagram of the vehicular light emitting panel. (A) is a block diagram of a vehicle light emitting panel according to a second embodiment, and (b) is a block diagram of a vehicle light emitting panel according to a modified example of the second embodiment.

A vehicle light emitting panel according to a first embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG. 1A is a front view of the vehicle light emitting panel according to the first embodiment, and FIG. 1B is a cross-sectional view taken along the line AA in FIG. 1A.
As shown in FIGS. 1A and 1B, a vehicle light emitting panel 1 according to the first embodiment includes a panel 2 installed inside a vehicle for transmitting information to the outside of the vehicle. , And mounting means 8 for holding the panel 2 in a non-pivotable manner.
Among them, the panel 2 includes a rectangular flat plate-shaped base body 3, a holding frame 4 having a U-shaped cross section and capable of holding the upper end surface 3 a of the base body 3, and the inside of the holding frame 4. The light emitting element 5 is provided along the upper end surface 3a by being housed in the 4a.
Further, on the surface 3b of the base body 3, the notation 6 representing desired information is formed. Specifically, the series of characters “under high-speed learning” that compose this notation 6 is a seal body that is made of a non-luminous material that blocks the light emitted by the light emitting element 5 and has an adhesive layer on the back surface. And is adhered to the surface 3b of the substrate 3 via this adhesive layer. However, the notation 6 may be formed by a paint applied to the surface 3b other than the seal body.
Further, the panel 2 is provided with a plug receiving port 7 for inserting the insertion plug P at the tip of the cable connected to the cigar socket, on the upper end surface 4b of the one end 4c of the holding frame 4.

More specifically, the panel 2 is a light guide plate in which the three light emitting elements 5 are housed in the inside 4a of the holding frame 4 and arranged at equal intervals along the upper end surface 3a of the base body 3. For example, the width W is about 50 cm, the height H is about 10 cm, and the thickness T is about 0.3 cm. Among these, the light emitting element 5 is an LED module in which six white LED elements are arranged in series on a strip-shaped substrate at intervals.
The base 3 is made of acrylic resin and has a general light guide plate configuration including a reflection sheet 3c and a diffusion sheet 3d. Therefore, the light emitted from the light emitting element 5 is emitted toward the diffusion sheet 3d after being reflected by the reflection sheet 3c. That is, the diffusion sheet 3d serves as the surface 3b of the base body 3.
Therefore, when the power supply from the cigar socket is started, the three light emitting elements 5 cause the light emitting region R of substantially uniform brightness to appear over the entire surface 3b of the base body 3. On the other hand, since the light from the light emitting region R is blocked by the notation 6 attached to the front surface 3b, the notation 6 is visible. On the contrary, since the light emitting region R does not appear when the power supply is cut off, the notation 6 becomes difficult to visually recognize.
In addition, by providing a switch (not shown) that can start or cut off the power supply from the cigar socket at a desired timing in the middle of the cable connected to the cigar socket, the timing of energizing the panel 2 Can be controlled easily.

Further, the upper end surface 4b of the holding frame 4 is provided with mounting means 8, 8 near the both ends 4c, 4c for holding the panel 2 in a non-pivotable manner. The mounting means 8 is composed of a resin suction cup 8a and a metal screw body 8b for fixing the suction cup 8a to the upper end surface 4b of the holding frame 4. Further, the suction cup 8a is provided with a substantially cylindrical base portion 8c on its protruding surface.
Therefore, in the mounting means 8, the screw body 8b is screwed and fixed to a place other than the surface 3b of the base body 3, for example, the upper end surface 4b of the holding frame 4, and the suction cup 8a is mounted to the inner surface of the window of the vehicle. As a result, the surface 3b of the base 3 faces the inner surface of the vehicle window.
In this way, since the holding frame 4 and the suction cup 8a are connected to each other via the screw body 8b so that they cannot swing, the panel 2 is also held so that it cannot swing with respect to the window. When the suction cup 8a is attached to the window, the suction surface 8d of the suction cup 8a becomes substantially parallel to the surface 3b of the base body 3 so that the surface 3b becomes substantially parallel to the inner surface of the window. The panel 2 is held in the.

Next, a usage state of the vehicle light emitting panel according to the first embodiment will be described with reference to FIG. FIG. 2 is a use state diagram of the vehicle light emitting panel according to the first embodiment. The constituent elements shown in FIG. 1 are designated by the same reference numerals in FIG. 2 and their description is omitted.
As shown in FIG. 2, in the light emitting panel 1 for a vehicle, the panel 2 is adsorbed and fixed to the inner surface of the rear window 51 of the vehicle 50, for example, via the attachment means 8 to thereby fix the panel 2 on the surface 3b of the base body 3. The notation 6 including the attached characters and symbols is clearly visible from the outside of the vehicle 50 when the light emitting region R appears.
Since the rear window 51 in FIG. 2 is attached so that its surface is substantially along the vertical direction, the surface 3b is also arranged along the substantially vertical direction, and the notation 6 can be easily visually recognized.
However, since the front surface 3b is held substantially parallel to the inner surface of the rear window 51 when the suction cup 8a is adsorbed to the rear window 51, even in the case of the rear window tilted from the substantially vertical direction toward the horizontal direction. , It becomes the same state. At this time, since the panel 2 is in a state of approaching the inner surface of the rear window, the notation 6 does not move backward toward the interior of the vehicle 50. Therefore, also in this case, the notation 6 can be clearly seen from the outside of the vehicle.

In the vehicle light-emitting panel 1 having the above-described configuration, the notation 6 made of the non-light-emitting material is visually recognized by setting the light-emitting region R as the background, and therefore the notation 6 is clearly indicated from the outside of the vehicle 50 regardless of day or night or the weather. Is recognized. In addition, since the notation 6 is made of a seal body and cannot be changed in real time, if it is possible to continuously transmit one type of information only in a specific scene, even if it cannot be changed in real time. There is no inconvenience. However, even in such a case, for example, a plurality of types of information can be transmitted depending on the scene by replacing a plurality of types of seal bodies in which characters representing different information are written.

As described above, according to the vehicle light emitting panel 1, since the notation 6 is clearly recognized from the outside of the vehicle 50, information can be reliably transmitted to the outside of the vehicle 50. Further, by fixing the notation 6 to one type, it is possible to limit the function and enhance the cost effectiveness. On the other hand, since the notation 6 can be selected from a plurality of types and can be re-attached, the vehicle light emitting panel 1 can appropriately realize the usage desired by the driver.
Further, when the notation 6 shown in FIG. 1 is applied to the vehicular light emitting panel 1, the vehicular light emitting panel 1 is always attached to the rear window of the training vehicle, and while the training vehicle is traveling on the highway. Among them, the usage method of supplying power to the light emitting element 5 is preferable. According to this usage method, the driver of the following vehicle approaching at high speed can be alerted promptly. Therefore, the driver of the following vehicle can be prevented from approaching the training vehicle abnormally, and the training vehicle can be easily overtaken, so that the safety of both vehicles can be ensured.

When the notation 6 shown in FIG. 2 is applied, the vehicle light-emitting panel 1 is always attached to the rear window of a general vehicle, and the vehicle is desired while traveling on a highway or a general road. It is preferable that the light emitting element 5 be supplied with electric power at the timing of (1) to cause another vehicle to recognize the notation 6.
Therefore, for example, when the driver gives up the course, the gratitude can be immediately transmitted, which can be expected to contribute to the prevention of the “flapping driving” which is a particular problem.
According to the vehicular light-emitting panel 1, the notation 6 can be visually recognized only by causing the light-emitting element 5 to emit light, and thus the operation during driving is easy. Therefore, in terms of operation, there is no concern that safety during traveling will be impaired.

Next, the configuration of the vehicle light emitting panel according to the first modified example of the first embodiment will be described with reference to FIG. FIG. 3A and FIG. 3B are enlarged views in which a part of the vehicular light emitting panel according to the first modified example of the first embodiment is enlarged and are taken along line AA in FIG. FIG. 3C is a cross-sectional view taken along the line when viewed from the same direction, and FIG. 3C is a view taken in the direction B in FIG. 3A. The components shown in FIGS. 1 and 2 are designated by the same reference numerals in FIG. 3, and the description thereof will be omitted.
As shown in FIGS. 3( a) to 3 (c ), a vehicle light emitting panel 1 ′ according to a first modification of the first embodiment is a mounting means that constitutes the vehicle light emitting panel 1 according to the first embodiment. Instead of 8, 8, attachment means 8', 8'are provided.
The attaching means 8'is a suction cup 8a, a support 8e arranged on the upper end surface 4b of the holding frame 4 and fixed to the upper end surface 4b via a screw body 8b, and a substantially square column provided on the protruding surface of the suction cup 8a. It is composed of a screw body 8f for fixing the shaped base portion 8c' so as to be tiltable with respect to the support body 8e. The configuration of the vehicle light emitting panel 1 ′ other than this is the same as the configuration of the vehicle light emitting panel 1 according to the first embodiment.

In the vehicle light-emitting panel 1 ′ having the above configuration, the suction cup 8 a is inclined to the holding frame 4 via the support body 8 e and the screw body 8 f so that the suction cup 8 a can be inclined upward from the horizontal (see white arrow). And is tiltably connected. Therefore, the panel 2 is also held so as to be tiltable with respect to the window. The tilting angle of the suction cup 8a can be freely adjusted by tightening and loosening the screw body 8f.
Therefore, according to the vehicle light emitting panel 1 ′, the panel 2 can be held by adjusting the inclination angle of the surface 3 b of the base body 3. Therefore, for example, when the vehicle light emitting panel 1 according to the first embodiment is attached to the rear window that is strongly inclined in the horizontal direction, the notation 6 appears to be reduced in the vertical direction, which may be rather difficult to read. .. On the other hand, according to the vehicular light-emitting panel 1 ′, there is no such possibility, and the meaning of the notation 6 can be understood at a glance. Other functions and effects of the vehicle light emitting panel 1 ′ are similar to those of the vehicle light emitting panel 1 according to the first embodiment.

Next, the configuration of the vehicle light emitting panel according to the second modified example of the first embodiment will be described with reference to FIG. FIG. 4A is a front view of a vehicle light emitting panel according to a second modification of the first embodiment, and FIG. 4B is a usage state diagram of the vehicle light emitting panel. The components shown in FIGS. 1 and 3 are designated by the same reference numerals in FIG. 4, and the description thereof will be omitted.
As shown in FIGS. 4A and 4B, the vehicle light emitting panel 9 according to the second modified example of the first embodiment includes mounting means 11 instead of the mounting means 8, 8.
This attachment means 11 includes substantially L-shaped metal frame bodies 12 and 12, U-shaped hooks 13 and 13, connection bolts 14 that connect the frame bodies 12 and 12 to the U-shaped hooks 13 and 13, respectively. 14 and fixing bolts 15 and 15 for fixing the vehicle light emitting panel 9 to the frames 12 and 12.

Next, the frame 12 is composed of one straight line portion 12a and the other straight line portion 12b orthogonal to the one straight line portion 12a. Of these, the other linear portions 12b and 12b each have a U-shaped cross section, and the base 10 can be housed therein. Further, the U-shaped hook 13 is connected to the one straight portion 12 a and is attached to the inner wall surface of the vehicle 50 which is close to the inner surface of the rear window 51. Further, the connecting bolt 14 connects the one straight portion 12a and the U-shaped hook 13, and the fixing bolt 15 fixes the base 10 of the vehicle light emitting panel 9 to the other straight portion 12b.

More specifically, the connecting bolt 14 is passed through a circular through hole 14a formed in the straight portion 12a and then screwed into a circular screw hole 14b formed in the U-shaped hook 13. On the other hand, the fixing bolt 15 has circular screw holes 15b and 15b formed in the base body 10 after penetrating through the places where the long through holes 15a and 15a respectively formed in the straight portions 12b and 12b are overlapped with each other. Be screwed into. The configuration of the vehicle light emitting panel 9 is the same as the configuration of the vehicle light emitting panel 1 according to the first embodiment except that the screw holes 15b and 15b are provided.

Here, in order for the vehicle light emitting panel 9 to be held by the mounting means 11, first, the U-shaped hooks 13 and 13 are formed on the upper edge and the roof (not shown) of the pillars (not shown) on both left and right sides which respectively form the inner wall surface. (Not shown), and the through holes 14a, 14a of the linear portions 12a, 12a on one side are further overlapped with the screw holes 14b, 14a of the U-shaped hook 13. Thereafter, the connecting bolts 14 and 14 are respectively inserted into the screw holes 14b and 14a and tightened, so that the mounting means 11 is mounted on the inner wall surface of the vehicle 50.
Then, the through holes 15a, 15a of the straight portions 12b, 12b are superposed on the screw holes 15b, 15b of the base body 10 and the fixing bolts 15, 15 are respectively inserted into the screw holes 15b, 15b and tightened. The vehicle light emitting panel 9 is attached to the attaching means 11. Since the through hole 15a of the straight portion 12b is long, the U-shaped hooks 13 and 13 can be attached to the inner wall surface of the vehicle 50 regardless of the vehicle width of the vehicle 50.

In the vehicle light emitting panel 9 having the above-described configuration, the base body 10 is held by the inner wall surface of the vehicle 50 via the mounting means 11. Therefore, the vehicular light emitting panel 9 is fixed at a position spaced from the inner surface of the rear window 51 by a certain distance, and thus is less likely to be affected by vibration due to opening/closing of the rear window 51. Therefore, even if the rear window 51 is vigorously closed, it is possible to prevent the vehicle light emitting panel 9 from dropping.
Further, as shown in FIG. 4B, the length of one of the linear portions 12a, 12a of the mounting means 11 is designed so that the other linear portion 12b, 12b is located below the lower edge of the rear window 51. By doing so, the other straight portions 12b and 12b can be hidden. Therefore, the appearance when the vehicle light emitting panel 9 is attached is also good. Other functions and effects of the vehicle light emitting panel 9 are similar to those of the vehicle light emitting panel 1 according to the first embodiment.

A vehicle light emitting panel according to a second embodiment of the present invention will be described in detail with reference to FIG. FIG. 5A is a configuration diagram of a vehicle light emitting panel according to the second embodiment, and FIG. 5B is a configuration diagram of a vehicle light emitting panel according to a modified example of the second embodiment. The components shown in FIGS. 1 to 4 are denoted by the same reference numerals in FIG. 5 and their description is omitted.
As shown in FIG. 5( a ), a vehicle light emitting panel 16 according to the second embodiment includes a panel 17 installed inside a vehicle compartment, and mounting means 8 for holding the panel 17 in a non-pivotable manner. 8 (see FIG. 1) is provided with mounting means (not shown).

Among them, the panel 17 has a rectangular flat plate-like base body 18, a plurality of light emitting elements 19 provided on the base body 18 to cause a light emitting region to appear on its surface 18a, and power is supplied to the panel 17 from a cigar socket 20. A plug receiving port 21a into which a plug at the end of the cable 21 is inserted. Specifically, the panel 17 includes a display unit 22 in which a plurality of light emitting elements 19 are arranged in a matrix on the surface 18 a of the substrate 18, and a storage medium 23 that transmits the contents of the notation 6 to the display unit 22. It is an electronic bulletin board provided with a pluggable connector 23a. The display color displayed by the light emitting element 19 is a three-color type, but may be a single-color type or an eight-color type. Further, the storage medium 23 is preferably one having a built-in flash memory such as a USB memory or an SD memory card.
A switch 24 that can start or cut off the power supply from the cigar socket 20 at a desired timing is provided in the middle of the cable 21. Therefore, by turning the switch 24 on and off, the timing of energizing the panel 17 can be easily controlled.

In the vehicle light-emitting panel 16 having such a configuration, the notation 6 is based on one kind of notation content registered in the storage medium 23 in advance, according to each position where the plurality of light-emitting elements 19 emit light and each light-emission intensity level. It is formed.
Therefore, in the vehicle light emitting panel 16, the notation 6 representing the desired information is displayed on the display unit 22 by changing the notation content registered in the storage medium 23. Further, since the switch 24 can be operated to control the energization timing to the panel 17, the most necessary information can be transmitted to the outside of the vehicle at an appropriate timing. Therefore, according to the vehicle light emitting panel 16, it is possible to exert an effect of alleviating dissatisfaction of the other vehicle, and it is possible to suppress the occurrence of the tilting operation. Other functions and effects of the vehicle light emitting panel 16 are similar to those of the vehicle light emitting panel 1 according to the first embodiment.

Next, as shown in FIG. 5B, the vehicle light emitting panel 25 according to the modified example of the second embodiment includes a panel 26 that is an electronic bulletin board instead of the vehicle light emitting panel 16 according to the second embodiment. ..
In addition to the display unit 22 of the vehicle light-emitting panel 16, the panel 26 has a receiving unit 27 that performs wired communication with the display unit 22 and receives a wireless signal transmitted from the transmitting unit 30 incorporated in the control device 29. A battery 28 for supplying electric power to the panel 26 and a charging port 28a connected to an external power source (not shown) are provided.
It should be noted that the control device 29 may be, for example, a navigation system installed in a vehicle, a smartphone, or the like on which an application for controlling the operation of the panel 26 is installed. Alternatively, blinking intervals of the plurality of light emitting elements 19 forming the display unit 22 are stored in advance. The configuration of the vehicle light emitting panel 25 other than this is the same as the configuration of the vehicle light emitting panel 16 according to the second embodiment.

In the vehicular light-emitting panel 25 having the above configuration, the notation content to be displayed on the panel 26 is selected from the input screen of the navigation system or the like, and a signal corresponding to this notation content is wirelessly transmitted via the transmission unit 30. As a result, the transmitted signal is transmitted to the display unit 22 via the reception unit 27 of the panel 26, and the notation content as selected is displayed on the display unit 22.
Therefore, according to the vehicular light-emitting panel 25, by operating the input screen of the control device 29, it is possible to easily select and display any of the plurality of types of notation 6. Therefore, it becomes possible to transmit different types of information to the outside of the vehicle in real time with one vehicle light emitting panel 25. The other actions and effects of the vehicle light emitting panel 25 are similar to those of the vehicle light emitting panel 16 according to the second embodiment.

The vehicle light emitting panels 1, 9, 16 and 25 according to the present invention are not limited to those shown in the first and second embodiments. For example, in the vehicle light emitting panels 1, 9 and 16, electric power may be supplied from a battery instead of the cigar socket. Further, the vehicle light emitting panels 1 to 25 may be attached to the windows on both sides of the rear seat instead of the rear window 51.
Further, the fixing position of the attachment means 8 is not particularly limited as long as it is a position other than the surface 3b of the base body 3. Then, in the attachment means 11, for example, ratchet hinges are provided in the middle of the one straight line portions 12a, 12a of the frame body 12, respectively, so that the one straight line portions 12a, 12a can be rotated with respect to the U-shaped hooks 13, 13. It may be configured to be movable. In this case, the vehicle light emitting panel 9 can be installed so as to be tiltable with respect to the vertical direction. Therefore, even when the rear window 51 is inclined, the vehicle light emitting panel 9 can be brought closer to the rear window 51, and the visibility of the notation 6 can be improved.
