Detailed Description
The present invention will be further described with reference to the drawings and examples, but the present invention is not limited to the examples, and all similar structures and similar variations using the present invention shall fall within the scope of the present invention. The use of the directions of up, down, front, rear, left, right, etc. in the present invention is only for convenience of description and does not limit the technical solution of the present invention.
Example 1
As shown in fig. 1, fig. 2 and fig. 3, the vehicle-mounted display device of the present invention includes a vehicle-mounted control unit, an electronic paper display 1, a wireless communication device 2 and a power supply 3, wherein the vehicle-mounted control unit includes a control module 4, the control module 4 is connected to a signal output terminal of the wireless communication device 2, a signal output terminal of the control module 4 is connected to a signal input terminal of the electronic paper display 1, and power supply terminals of the control module 4, the wireless communication device 2 and the electronic paper display 1 are connected to the power supply 3.
Further, the wireless communication device 2 is a bluetooth module or a 4G communication module.
Further, the control module 4 and the electronic paper display 1 are disposed in the same housing.
Specifically, the vehicle-mounted control unit, the electronic paper display 1, the wireless communication device 2, the power supply 3, the control module 4, the bluetooth module, the 4G communication module, and the like in this embodiment all adopt known schemes in the prior art, and those skilled in the art will understand that details are not described herein.
The working principle of the embodiment is as follows: when the vehicle is started, power is supplied to the Bluetooth module and the electronic paper display 1, the mobile phone is connected with the vehicle-mounted control unit through the Bluetooth module, the electronic display reads the mobile phone of a driver or relevant edited information through a control module 4 of the vehicle-mounted control unit (such as Carplay), and at the moment, the electronic paper display 1 displays the mobile phone number of the connected person or displays the information edited by the driver through the mobile phone. After the driver stops and leaves, the electronic paper display 1 keeps displaying the original mobile phone number or the edited information of the driver until the next vehicle starts.
The display principle of the electronic paper display 1 is to control the movement of the colored electronic capsule by changing the polarity of the electrodes to realize the display function, and the greatest advantages are that: 1. the display can still keep original display content for a long time after power failure, 2, the visibility is high under sunlight, 3, the display belongs to flexible display, can be bent at will, and is very thin and convenient to mount. The electronic paper display 1 is mainly responsible for displaying information transmitted by the wireless communication device 2, such as a bluetooth module.
The bluetooth module is used only by way of example, the utility model is not limited to use of the bluetooth module, and other mobile devices can be connected in other ways to acquire the mobile phone number of the driver or the edited information, and the bluetooth module is mainly used for connecting with the mobile phone and transmitting the related information on the mobile phone.
The vehicle-mounted display device is convenient to install and use, solves the problem that information on paper cannot be changed at any time and quickly in the prior art, can display and update the mobile phone number of a driver or the information edited by the driver in time when the driver or others drive a vehicle, and is very simple and convenient to update.
