  These conventional techniques have a problem that the installation area of the solar cell depends on the size of the device, and a sufficient amount of power generation cannot be obtained. In addition, since the display unit is small compared to the device size, there is a problem that if more information can be displayed, images and characters become smaller and difficult to see. On the contrary, when the display screen is enlarged with these prior art devices, the more the solar cell is installed so that the amount of received light can be increased, the more difficult it is to see the screen due to the influence of sunlight.

  Then, an object of this invention is to provide the vehicle-mounted information display apparatus which can receive sufficient quantity of sunlight, and a screen display does not become difficult to see.

An information display device of the present invention made to achieve the above object is an in-vehicle electronic device configured to be installed on a dashboard so that a driver can visually recognize a display unit at least from the front. It also has a configuration.

  According to this information display device, the solar panel is in the above-described rotational support state by the awning member being pivotally supported by the main body case via the side surface portion. Moreover, since a sunshade member can also prevent that sunlight injects into a display part from the side by a side part, it can make a screen easier to see.

The information display device including the awning member may further include the following configuration.
(5) The left and right side portions have a tapered shape that decreases in height from the rear end to the front end.

  In the information display device of the present invention, it is desirable to enlarge the upper surface portion of the sunshade member on which the solar panel is to be installed. In such a case, it is possible to suppress an impression that the side surface portion is obstructive while giving strength to the bending moment due to the weight of the upper surface portion in a balanced manner.

Moreover, the information display apparatus provided with these awning members may further include the following configuration.
(6) The sunshade member is provided with an inclination holding function capable of rotating the front end side of the upper surface portion in the swing-up direction and capable of holding the state of being swung up to a predetermined angle.

  For example, a screw can be attached to the rotation support portion so that the screw can be tightened in a state where the rotation support portion is rotated to a desired angle, or a rotation support portion provided with a latch mechanism is used to adjust the inclination angle in a predetermined angle unit. It can be realized by various modes such as being configured so that it can be changed and held. By providing this (6) tilt holding function, the sunshade can be used by rotating the sunshade member at an angle that does not interfere with driving, exhibits a sufficient sunshade effect, and is easily exposed to sunlight. It becomes convenient.

Furthermore, the information display device provided with at least an awning member may further include the following configuration.

FIG. 9 is a longitudinal sectional view of a modified example.

  Hereinafter, specific examples will be described in detail with reference to the drawings as embodiments of the present invention.

  As Example 1, an information display device 1 that is an in-vehicle electronic device for monitoring and displaying speed control information will be described. As shown in FIG. 1, the information display device 1 includes a liquid crystal display panel 11 on the front surface, and a main body case 10 having an L-shaped longitudinal section in which a battery housing portion 12 projects rearward from a lower back portion. And a solar panel 31 installed so as to project forward from the upper part of the main body case 10, and a rechargeable battery 32 for charging the power generated by the solar panel 31 is stored in the battery storage unit 12. The power from the rechargeable battery 32 can be used as a power source for various displays.

  The solar panel 31 is installed on the upper surface portion 21 of the sunshade member 20 that is rotatably supported on the upper portion of the main body case 10. The awning member 20 is formed of a U-shaped cross-section with a side portion 22, 22 extending downward from the left and right of the upper surface portion 21, and the main body case via the rear end sides of the left and right side portions 22, 22. 10 is supported and fixed by a support member 23 so as to be rotatable. Further, the left and right side surface portions 22 and 22 have a tapered shape that decreases in height from the rear end portion toward the front end, and in the present embodiment, has a substantially right triangle shape in a side view.

  A bracket 51 for installing the information display device 1 on the dashboard is attached to the bottom surface of the case body 10. The information display device 1 can be installed at a desired position on the dashboard by an appropriate method such as sticking with a double-sided tape through the bracket 51.

  As shown in FIG. 1D, the upper surface portion 21 of the awning member 20 is provided with a rectangular recess 24 that is installed so that the solar panel 31 is fitted therein. The recess 24 occupies an almost entire area of the upper surface portion 21 of the sunshade member 20 and has a structure in which a solar panel 31 having substantially the same area as the upper surface portion 21 can be installed.

  As shown in FIGS. 2 (A) and 2 (B), the sunshade member 20 can rotate in either the direction in which the front end side of the upper surface portion 21 is swung up or the direction in which it is swung down with the support member 23 as the center of rotation. Thus, the tilt angle of the upper surface portion 21 can be maintained while being swung up or down to a desired angle. Such an inclination holding function can be realized by fixing the fit between the support member 23 and the main body case 10. It is also possible to provide a latch mechanism inside, or to provide a mechanism in which the support member 23 has a screw structure, is loosened to change the tilt angle, and is tightened to hold the tilt angle.

  In the present embodiment, when the vertical distance L2 from the rotation center of the sunshade member 20 to the upper surface is swung up to the maximum vertically upward, an open space is formed between the rear end of the battery storage portion 12 and the distance S1. The distance is used (see FIG. 2A). Further, the length L1 in the front-rear direction of the upper surface portion 21 of the sunshade member 20 is parallel to the front surface of the liquid crystal display panel 11 when the front end is swung down to the maximum, and the front surface of the panel 51 can be covered. The length is such that the position is raised by a distance S2 (see FIG. 2B).

  Further, as shown in FIG. 1D, the main body case 10 has a first substrate 41 provided with an electronic circuit for displaying information via the liquid crystal display panel 11, and a patch for the radar module. A second substrate 42 on which the antenna is installed on the back side is installed with a space in the front-rear direction in a vertically placed state. Further, a GPS module is installed on any one of the substrates 41 and 42, and the liquid crystal display panel 11 is installed on the basis of information acquired through the GPS module and the radar module and information stored in the electronic circuit. On the other hand, it is a device that displays information for monitoring the speed control.

  For GPS module installation, as shown in FIG. 2 (C), a horizontal third substrate 43A may be provided at the upper position between the first substrate 41 and the second substrate 42. Good. In this case, some functions of the GPS module may be provided on the second substrate 42. Alternatively, the third substrate 43B may be installed horizontally on the rechargeable battery 32 to include a GPS module. In the present embodiment, when the sunshade member 20 is swung up to the maximum, an open space with a distance S1 is formed between the rear end of the battery housing 12 and the radio wave to the GPS module is not blocked.

  According to the present embodiment, the solar panel 31 is installed on the upper surface portion 21 of the sunshade member 20 provided on the upper portion of the main body case 10 so as to protrude forward from the display panel 11, so that FIG. As shown in FIG. 5, the solar panel 31 having a sufficiently large length L3 in the front-rear direction compared to the depth D1 of the main body case 10 can be provided, and the amount of power generation can be greatly increased. Further, the solar panel 31 and the awning member 20 also serve as a sun visor for the information display device 1, and the display panel 11 is not easily seen by sunlight. As a result, according to the present embodiment, the restrictions on the area of the solar panel are greatly relaxed, and in addition to the increase in power generation by the large area solar panel, a display panel with higher brightness and higher resolution than the conventional one is used. It will not be difficult to see.

  Further, since the rechargeable battery 32 is housed in the battery housing portion 12 protruding rearward from the lower back of the main body case 10, there is a forward tipping moment due to the solar panel 31 protruding forward at the upper part. When the vehicle is balanced, the installation is stable, and the vehicle vibrates as the vehicle travels, or the information display device is accelerated.

  Further, the information display device 1 of the embodiment rotates the solar panel 31 according to the incident angle of the direct sunlight incident through the windshield by setting the inclination angle of the solar panel 31 to a desired angle, and displays The direct sunlight around the part can be appropriately shielded by the solar panel 31 and the awning member 20, and the display can be made easier to see. When not in use, it can be rotated to a position where it does not get in the way.

  In addition, the side portions 22 and 22 of the awning member 20 on which the solar panel 31 is installed can firmly support the rotation of the main body case 10, and sunlight is incident on the display unit from the side. Therefore, it is possible to make the screen easier to see. Moreover, since the left and right side surface portions 22 and 22 have a tapered shape whose height decreases as going from the rear end portion to the front end, the case where the upper surface portion 21 of the awning member 20 is increased in order to increase the power generation amount. The side portions 22 and 22 do not give a disturbing impression while giving strength in a balanced manner against the bending moment due to their own weight.

  In addition, when the awning member 20 is swung up to the maximum, it does not protrude rearward, and when it is swung up to the maximum, it does not hit the dashboard, and it is also possible to reduce the packing form at the time of shipment. Yes. In the state where it is swung down, the front surface of the display panel 11 can be covered, and it also serves as a protective cover for the display panel 11.

  Since the solar panel 31 is on the upper surface, the antenna performance on the back side of the main body is less affected, information on the presence / absence of reception of radar waves can be accurately displayed, and no adverse effect on the original function of the device is caused. In addition, it is not necessary to increase the depth of the main body case 10 in order to secure the area of the solar panel 31, and it can be implemented as a compact device having a large display unit without impairing the radar detection function and the GPS positioning function. Even when a variety of information is displayed on the large display section, it is possible to prevent the corner information display from becoming difficult to see with sunlight. As a result, the luminance of the display unit can be suppressed, power consumption can be suppressed, and ultimately, it can be used only with a solar power source from a solar panel.

  In this embodiment, as shown in FIG. 2C, when the solar panel 31 is horizontal, the main body case 10 and the awning member 20 have the back surfaces 10b and 20b flush with each other. 10 and the lower surface 21a of the upper surface portion 21 of the sunshade member 20 are substantially in contact with each other. The upper and lower portions of the upper part of the main body case 10 have a slightly rounded cross-sectional shape so as to have a structure that can naturally exhibit the tilt holding function when the rotation angle is desired by contact without hindering the rotation operation. It has become. As shown in FIG. 2D, when the upper surface of the main body 10 has an R shape that is substantially concentric with the center of the rotation axis, the rotation operation can be made smoother. In this case, an elastic member such as an elastomer may be provided in the contact portions P1, P2, etc. so that the upper surface of the main body 10 and the lower surface of the upper surface portion 21 of the sunshade member 20 are lightly contacted and held at an angle. As can be seen from the maximum swing-up state in FIG. 2 (A), the rear surface of the upper surface portion 21 of the sunshade member 20 can be further extended rearward in a rotatable configuration. Moreover, you may install a solar panel also in the side parts 22 and 22 of the sunshade member 20. As shown in FIG. In this way, the configuration in which the solar panel is installed so as to extend at least forward with respect to the display unit does not affect the main body structure of the device, so the rear end side is extended further rearward or the left and right widths are increased. By making it larger than the main body case 10, a solar panel with a larger area can be installed.

  As mentioned above, although the Example for implementing this invention was described, this invention is not limited to these, The various change in the range which does not deviate from the summary is possible.

  For example, the battery storage unit 12 may be configured separately from the main body case 10 instead of being integrated with the main body case 10, and may be configured so as to be integrated with the main body case 10 by connector connection when installed in a vehicle, or may be separately installed by cable connection. Absent. Applications can also be applied to car navigation devices and other in-vehicle electronic devices.

  The present invention can be used in in-vehicle electronic devices for automobiles.
