Hereinafter, details of the in-steering wheel display device according to the present invention will be described based on an embodiment shown in the drawings.
[0026]
(1st Embodiment)
1 to 3 show a first embodiment of the present invention. FIG. 1A is a front view of a steering wheel 1, FIG. 1B is a cross-sectional view taken along line AA of FIG. 3A is an enlarged sectional view showing details of the design unit 6, FIG. 3A is a front view of the steering wheel 1 showing a display state of the steering rotation information when the vehicle is turned left, and FIG. FIG. 3 is a front view of the steering wheel 1 showing a display state of rotation information.
[0027]
As shown in FIGS. 1A and 1B, a steering wheel 1 on which a display device A1 in a steering wheel is mounted is fixed to an upper end of a steering shaft (not shown) and fixed to a steering shaft (not shown). And a circular wheel main body 3 fixed to the tip of the three-way support rod 2.
[0028]
The wheel body 3 has an elliptical cylindrical cross section and is disposed on the lower half of the circular shape, and the opaque resin member 4 is disposed on the upper half of the circular shape and fixed to both ends of the opaque resin member 4. And a light transmitting member 5 formed.
[0029]
On the surface of the opaque resin member 4, a design such as woodgrain or silver tone is applied by printing or the like. The light transmitting member 5 is composed of two layers: a transparent resin layer 5a made of a polycarbonate material disposed on the outer surface side and a transparent resin layer 5b made of a polycarbonate material disposed on the inner surface side. A design section 6 described below is provided on the inner surface of 5b.
[0030]
A cylindrical iron core 7 is built in the wheel body 3, and an LED substrate 8 is fixed to the iron core 7. The LED substrate 8 has an arc shape and is fixed at an internal position of the light transmitting member 5. A large number of light emitting diodes 9a to 9k, which are display devices, are provided on the driver-side surface of the LED substrate 8.
[0031]
A large number of light emitting diodes 9a to 9k are arranged at an interval in the left-right direction about the center position above the steering wheel 1 located at the neutral position. The plurality of light emitting diodes 9a to 9k are selectively driven by a control unit (not shown), and the control unit (not shown) is driven to turn on in conjunction with the rotation of the steering wheel 1, and the current steering is performed. The number of light emitting diodes 9a to 9k corresponding to the amount of rotation of the wheel 1 is turned on.
[0032]
Further, a black opaque resin 10 is filled in the internal space of the light transmitting member 5 and on the side of the LED substrate 8 opposite to the light emitting diodes 9a to 9k. The opaque resin 10 is for ensuring the grip strength of the light transmitting member 5 and for making the inside of the light transmitting member 5 inconspicuous by external light.
[0033]
As shown in detail in FIG. 2, the design unit 6 includes a light shielding region S1 that blocks light from the light emitting diodes 9a to 9k, and a light transmitting region S2 that transmits light from the light emitting diodes 9a to 9k. These are alternately arranged at fine intervals. A print layer 17 is provided in the light shielding region S1, and the print layer 17 reflects a light in a design print layer 17a having a woodgrain or silver tone design in order from the driver side. It is composed of a white white printed layer 17b and a black printed layer 17c that absorbs and blocks light, and the design printed layer 17a is adhered to the printing transparent resin layer 5b.
[0034]
The printing layer 17 is provided by directly printing on the printing transparent resin layer 5b, or by attaching a printed sheet to the printing resin layer 5b. The design of the design print layer 17a is generally the same as the design of the opaque resin member 4 of the wheel body 3 described above. Nothing is arranged in the light transmission area S2 so that light is transmitted by the air layer.
[0035]
In the above configuration, when the steering wheel 1 is positioned in the straight traveling direction during driving, none of the light emitting diodes 9a to 9k is driven to be lit. In such a situation, the external light is partially reflected and partially absorbed by the design print layer 17a, and the light transmitted through the design print layer 17a is reflected by the white print layer 17b, whereby the design of the design print layer 17a is reduced. Looks prominent. In other words, the entire wheel body 3 appears to the driver as one designed with wood grain, silver, or the like.
[0036]
In this state, as shown in FIG. 3A, when the steering wheel 1 is rotated leftward L, a large number of light emitting diodes 9a to 9k are displaced in the leftward rotation direction together with the wheel body 3, and the steering wheel is rotated.

When even one of the light emitting diodes 9a to 9kc is driven to be lit in this way, of the irradiation light from the light emitting diodes 9a to 9k, the light that has entered the light shielding region S1 is blocked by the black print layer 17c. Therefore, the light does not enter the design print layer 17a, so that the design of the design print layer 17a cannot be seen. Since the light that has entered the light transmitting area S2 is transmitted to the surface side of the light transmitting member 5, the driver does not see the upper half of the wheel body 3 designed as wood grain, silver, or the like. Light emitting diodes 9a to 9k can be seen. When rotating in the left direction L, the light emitting diodes 9a to 9k are lit on the left side of the wheel body 3, and when rotating in the right direction R, the light emitting diodes 9a to 9k are lit on the right side of the wheel body 3. In addition, the number of light emitting diodes 9a to 9k corresponding to the rotation amount of the steering wheel 1 is turned on, so that the turning direction and the rotation amount at the time of cornering are displayed on the steering wheel 1.

Furthermore, since the light emitting diodes 9a to 9k cannot be seen from the interior of the vehicle by the design layer, the appearance is not impaired.
[0041]
In the first embodiment, the rotation information of the steering wheel 1 is the rotation direction and the rotation amount, and the light emitting diodes 9a to 9k located on the rotation side of the steering wheel 1 are turned on to indicate the rotation direction. Since the number of light emitting diodes 9a to 9k corresponding to the amount of rotation of 1 is turned on to indicate the amount of rotation, not only the rotation direction of the steering wheel 1 but also the magnitude of the amount of rotation can be recognized, so that more complete driver assistance information can be obtained.

For example, the configuration is such that rotation information of the steering wheel 1 is analyzed from map information of a back monitor (not shown) or navigation (not shown), and the light emitting diodes 9a to 9k are driven based on the analysis information. Then, since the rotation information of the steering wheel 1 is displayed based on the back monitor and the map information of the navigation, an accurate steering operation can be easily performed.
[0044]
When both the rotation information of the steering wheel 1 to be performed next and the current rotation information of the steering wheel 1 are displayed together, it is preferable that both display states be different from each other in order to distinguish them. For example, the blinking display is performed at the time of the next rotation information of the steering wheel 1, and the lighting display is always performed at the time of the current rotation information of the steering wheel 1.
[0045]
In the first embodiment, since the design portion 6 is provided on the inner surface of the light-transmitting member 5, even if the driver grips the wheel body 3 of the steering wheel 1 for many years, the design portion 6 may be worn or peeled off. I can't.
