Description

Vehicle head display device

This creation is about a vehicle head-up display device, especially a device that integrates driving information, navigation information, reversing information, and information such as Bluetooth communication on the display.

The car head-up display is mounted on the dashboard of the car to project driving information onto the windshield of the car in front of the driver's seat, and can directly fall into the line of sight in front of the driver, allowing the driver to look directly while driving. The speed of driving or other driving information, without having to look up or bow down to change the line of sight, to improve the safety of driving, and is very popular with drivers.

However, there are too many traffic signals today, such as navigation, driving information, reversing information and telephone call information, etc., so many different information display devices are often placed on the car, which not only takes up space but also increases the cost of purchasing for consumers. .

In view of the above needs, the creator is constantly developing and improving, and research and development A signal for collecting driving information, navigation information, reversing information, and information such as Bluetooth communication is integrated into a display, so that the vehicle head-up display device has a plurality of signal display functions, mainly by a display device installed in the vehicle. The display device receives the driving computer (including driving information such as speed limit, overspeed detection, reversing information, such as reversing radar, etc.) and the car audio and video host (signal processing reception), via the signal decoder, and then It is processed by the car audio and video host, and finally transmitted to the display, and the signals are transmitted to the windshield.

The reason is that in order to achieve the above objectives, the main purpose of this creation is to integrate the signals of driving computer signals and car audio and video mainframes into the display to enhance and provide better information display to meet the needs of users.

Another purpose of this creation is to provide a multi-signal display to enhance the function of the vehicle head-up display device. It is possible to save the purchase cost and not occupy the space of the vehicle without having to purchase a display with a plurality of different signals. Car head-up display device.

In order to enable your review board to further understand the practical effects of this creation, the following detailed description of the preferred embodiment with the drawings is as follows: Please refer to the first and second figures. This creation is mainly installed by one. The display device 2 of the in-vehicle 1 receives the signals of the driving computer 3 and the car audio and video host 4, respectively, via the signal decoder 5, and then through the car audio and video host 4, and finally to the display 6, and Each signal is transmitted and projected onto the windshield 11, wherein the driving computer 3 includes driving information 31 (speed limit, overspeed detection, etc.), reversing information 32, etc. (such as reversing radar, etc.), and the signal decoder 5 and the car audio and video host 4 transfer each other; the car audio and video host 4, the package navigation 41, the Bluetooth module 42 and the data transmission protocol 43, after receiving various information signals, using transmission lines or Bluetooth, etc. Display 6; The display 6 includes a displayable screen 61 and receives signals transmitted from the car audio and video main unit 4, and can be projected onto the windshield 11 by the display screen 61.

If yes, the driving computer 3 detects each signal, decodes it by the signal decoder 5, processes it through the car audio and video host 4, and then transmits it to the display 6, which can be projected on the windshield 11 for driving reference. The display screen is mainly based on the display direction indicator pin, speed limit, speed and display section, and the caller ID reversing information will be displayed and adjusted according to the current situation; the following is a description of the creation example: Please refer to the figure shown in the third figure for the creation of the original (initial screen); please refer to the figure shown in the fourth picture, that is, the creation of the general driving state (ie, speed, speed warning, speed camera warning, etc.) It has navigation function, compass and other display functions, and the reversing information can also have warning symbols. The tire pressure detection and lane offset are also detected and displayed to remind the driver in all directions. The created Bluetooth module is displayed on the display (projected on the windshield), and the display of the caller-free device can be realized without looking at the mobile phone, which is more practical and convenient to use.

Please refer to the figure shown in the fifth figure. When the navigation destination is not entered during driving, the navigation message will display the “now road name” display. Otherwise, if you enter the navigation to set the destination, the road name will be The display screen of "Road junction road name" is displayed.

Moreover, the display screen 61 of the present invention is an LCD panel, and the panel can be directly viewed directly.

The above-mentioned creations are specific embodiments of the present invention, but the present invention is not limited thereto, that is, the simple equivalent changes and modifications made according to the scope of the novel application and the contents of the specification can be covered in the following patent scope of the present invention.
