Description

Technical Field

[0001] This utility model relates to the technical field of LCD dynamic map display screens, specifically an LCD dynamic map display screen with an electronic ink screen. Background Technology

[0002] Dynamic map displays are a high-tech information display device widely used in rail transit, digital signage, outdoor high-brightness applications, and other fields. The application of dynamic map displays is most widespread in the rail transit field, such as subways and light rails. It can display train arrival information, route maps, transfer information, etc. in real time, providing passengers with convenient travel services. Currently, the dynamic map displays or information displays used in subways, high-speed rails, and buses are all stand-alone LCD displays.

[0003] Currently, existing LCD displays have many advantages, and e-ink displays also have some advantages. However, there is currently no dynamic map product or similar product that combines an LCD screen and an e-ink screen. Traditional LCD products have higher power consumption than e-ink screens. Furthermore, when the backlight or controller of an LCD product malfunctions, the screen will go black, and passengers will not be able to see the content displayed on the screen, which will cause inconvenience to passengers. On the other hand, e-ink screens have a relatively slow update speed, and it is difficult to meet the requirements of vehicles that need to quickly change the image when used alone. Therefore, this application provides an LCD dynamic map display screen with an e-ink screen to meet the needs. Utility Model Content

[0004] The purpose of this invention is to provide an LCD dynamic map display screen with an electronic ink screen to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LCD dynamic map display screen with an electronic ink screen, comprising a mounting shell, a protective glass fixed on one side of the mounting shell, an LCD screen installed inside the mounting shell, a control board installed on the rear side of the LCD screen, fixing slots on both sides of the interior of the mounting shell, an electronic ink screen body installed on both sides of the interior of the mounting shell, fixing buckles fixed on the upper and lower sides of the electronic ink screen body, fixing plates fixed on both sides of the rear of the electronic ink screen body, a connecting cable installed on the rear side of the electronic ink screen body, and a USB plug fixed at one end of the connecting cable.

[0006] Preferably, there are two electronic ink screen bodies, which are symmetrically arranged about the central axis of the LCD screen.

[0007] Preferably, the main body of the electronic ink screen is connected to the mounting shell by a fixing buckle, and the shape of the fixing buckle conforms to the fixing groove.

[0008] Preferably, the USB plug is inserted into one side of the control board, and the USB plug is symmetrically arranged with respect to the central axis of the control board.

[0009] Preferably, the mounting housing is fixed with mounting bases on both rear sides, and bolts pass through the top of the mounting bases.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. This LCD dynamic map display screen with an e-ink screen, through the combined use of an LCD screen, control board, mounting slot, e-ink screen body, fixing buckle and USB plug, allows the dynamic map used in subways, high-speed rails and buses to be displayed on two screens, increasing the display area and enriching the display content. Moreover, the e-ink screen body has very low power consumption, making the device more green and environmentally friendly. When the device's power supply or backlight is abnormal, the e-ink screen body's power-off retention function can still display the last image, avoiding the situation where traditional dynamic maps completely fail to display when abnormalities occur, and ensuring that passengers cannot see relevant information.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3This utility model provides a technical solution: an LCD dynamic map display screen with an e-ink screen, including a mounting shell 1, a protective glass 2 fixed to one side of the mounting shell 1, an LCD screen 3 installed inside the mounting shell 1, a control board 4 installed on the rear side of the LCD screen 3, fixing slots 5 on both sides of the interior of the mounting shell 1, and e-ink screen bodies 6 installed on both sides of the interior of the mounting shell 1. Two e-ink screen bodies 6 are provided, symmetrically arranged around the central axis of the LCD screen 3. By combining the e-ink screen bodies 6 and the LCD screen 3, the dynamic map used in traditional subways, high-speed trains, and buses can be displayed on two screens, increasing the display area and enriching the display content. When the device power supply or backlight is abnormal, the power-off retention function of the e-ink screen body 6 can still display the last image. Fixing buckles 7 are fixed to the top and bottom sides of the e-ink screen body 6. The main body 6 is connected to the mounting shell 1 by a fixing buckle 7. The fixing buckle 7 and the fixing groove 5 are shaped to facilitate the splicing and installation of the e-ink screen main body 6. The installation structure is relatively stable. Fixing plates 8 are fixed on both sides of the rear of the e-ink screen main body 6. A connecting cable 9 is installed on the rear of the e-ink screen main body 6. A USB plug 10 is fixed to one end of the connecting cable 9. The USB plug 10 is inserted into one side of the control board 4. The USB plug 10 is symmetrically arranged with the central axis of the control board 4. When the USB plug 10 is inserted into one side of the control board 4, the control board 4 can send relevant information commands to the information input interface of the e-ink screen main body 6 through the connecting cable 9, thereby controlling the display content of the e-ink screen main body 6. Fixing seats 11 are fixed on both sides of the rear of the mounting shell 1. A bolt 12 passes through the top of the fixing seat 11. The bolt 12 is screwed into the fixing seat 11 through the top of the fixing plate 8 to fix the e-ink screen main body 6.

[0018] Working Principle: When using this LCD dynamic map display screen with an e-ink screen, first connect the external power supply. Then, use the fixing clips 7 to secure the e-ink screen body 6 to both sides inside the mounting housing 1. Simultaneously, screw the bolts 12 through the top of the fixing plate 8 and screw them into the fixing base 11. At the same time, insert the USB plug 10 into one side of the control board 4, so that the control board 4 can send relevant information commands to the information input interface of the e-ink screen body 6 through the connection cable 9, thereby controlling the display content of the e-ink screen body 6. By combining the e-ink screen body 6 and the LCD screen 3, the dynamic map used in subways, high-speed trains, and buses can be displayed on two screens, increasing the display area and making it more convenient for passengers to view. Secondly, when the device power supply or backlight is abnormal, the power-off retention function of the e-ink screen body 6 can still display the last image, avoiding the situation where there is no display at all when a traditional dynamic map malfunctions. Passengers can still see relevant information on the e-ink screen body 6. When not using the device, disconnect the external power supply. This completes the usage process of the LCD dynamic map display screen with an e-ink screen.
