Embodiment 1

[0031] Such as Figure 1-8 As shown, the external scrolling display device for the driving status of the vehicle includes a power supply unit, a display unit, a graphics processing unit and a detection input unit. The detection input unit receives the electrical signal sent by the vehicle control system, converts it into a digital signal, and transmits it to the graphics processing unit. The unit performs graphics segmentation and drive processing, and the graphics processing unit transmits the output digital pulse signal to the display unit, so that the display unit sends out corresponding warning graphics, and the power supply unit is connected to the vehicle power supply through a power converter. The power converter stably reduces the 18-32 volt DC voltage of the vehicle to the voltage required by the device to supply each power-consuming part, and the step-down method adopts a DC inverter method.

[0032] The graphics processing unit is driven by a single-chip microcomput...

Embodiment 2

[0036] Such as Figure 9 As shown, the external scrolling display device for the driving state of the vehicle also includes a light sensor connected to the power supply unit for detecting ambient light to control the brightness of the LED display. Other structures are with embodiment 1.

Embodiment 3

[0038] Such as Figure 10 As shown, the external scrolling display device for vehicle driving status also includes an audible and visual alarm unit connected to the auxiliary interface of the display device for prompting drivers and pedestrians; the audible and visual alarm unit is a buzzer. Other structures are with embodiment 1.

[0039] Such as Figure 11 As shown, the display screen of the present invention is installed on the front and rear sides of the vehicle, and the quantity can be determined according to the size of the vehicle. For example, one can be installed at the front and rear lights of electric vehicles (bicycles need to install one at the front and rear after the original car circuit system is installed), cars can have two symmetrical installations at the front and rear lights (headlights and brake lights), buses, and large trucks Large vehicles such as school buses, engineering vehicles, etc. can be installed four or more at the front and rear, and can al...

Abstract

The invention discloses a vehicle running state external scrolling display device. The vehicle running state external scrolling display device comprises a power source unit, a display unit, a graphics processing unit and a detection input unit. The vehicle running state external scrolling display device is characterized in that the detection input unit receives an electric signal sent by a vehicle control system, converts the electric signal into a digital signal and transmits the digital signal to the graphics processing unit so that graphics dividing and driving processing can be conducted; the graphics processing unit transmits the output digital pulse signal to the display unit, so that the display unit sends corresponding caution graphics; and the power source unit is connected with a vehicle-mounted power source through a power converter. The vehicle running state external scrolling display device has the beneficial effects that the running state, direction and speed of a vehicle can be clearly expressed through changing of different scrolling speeds, scrolling directions and scrolling colors of running state scrolling display lamps installed outside the front portion and the rear portion of the vehicle, and accordingly other people can easily know about the running state of the vehicle and correctly respond in the first time.

Description

technical field [0001] The invention relates to a vehicle display device, in particular to an external rolling display device of a vehicle running state, and belongs to the technical field of automobile lighting. Background technique [0002] In the design of existing car lights, taking headlights as an example, they are mainly used to provide driving light illumination, and usually have the function of switching between far and near lights. The function of the existing headlights is only used for driving lighting, and does not have other lighting effects. Similarly, the existing direction lights only have the function of warning the turning direction, and the brake lights only have the function of warning the brakes. The above-mentioned headlights, direction lights or brake lights only have a single lighting mode and function, and their product competitiveness is relatively poor, and their use is relatively monotonous and unchanged. Therefore, the applicant in this case b...
