Description

Technical Field

[0001] This utility model relates to a smart digital screen, specifically a smart digital screen. Background Technology

[0002] Road signs are common road signage devices. Their purpose is to help drivers identify roads and avoid taking the wrong turn while driving.

[0003] Currently, road signs with LED displays are common in urban areas (such as Chinese patent, publication number: CN105741692A, which discloses a photovoltaic LED backlit road sign light). Compared with traditional road signs, electronic road signs are more eye-catching, especially during long drives, and are more likely to attract the driver's attention so that the driver can obtain road information in a timely manner.

[0004] In existing technologies, including the aforementioned patents, highways rarely feature road signs with LED displays; they still rely on traditional, outdated signs. With the increasing need for highway maintenance and widening, a common approach to ensure normal traffic flow is to divide the road in half, constructing one half and leaving the other half untouched. To prevent accidents, construction sections are fenced off and additional warning signs are added. While daytime visibility is acceptable, at night it relies entirely on the reflection of vehicle headlights, making it less effective than road signs with LED displays, which are more likely to attract drivers' attention.

Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-6 As shown, a digital smart screen includes an aluminum mounting frame 1 and a display module 2 and an audio speaker 3, which are respectively fixedly installed in mounting slots opened vertically along the aluminum mounting frame 1.

[0036] Display module 2 includes LED display light modules 21 arranged in a matrix.

[0037] Specifically, in this embodiment, the control circuit board can be mounted on the aluminum mounting frame 1. The control circuit board integrates a storage module, a PLC processor, a USB interface module, or a network transmission module. It can be connected via USB to the USB interface module to input characters to be displayed by the display module 2, or remotely controlled via the network transmission module to input characters to be displayed by the display module 2. The entire device can be powered by a photovoltaic panel or directly connected to a 220V AC power supply. The aforementioned electronic components and control programs are common knowledge to those skilled in the art and therefore will not be described in detail.

[0038] Furthermore, the aluminum mounting frame 1 is composed of several aluminum sheet metal components, including an outer frame and a central crossbar. The crossbar divides the interior of the outer frame into an installation station for the display module 2 and an installation station for the speaker 3. The input terminals of both the display module 2 and the speaker 3 are connected to the control circuit board.

[0039] In the above technology, the display module 2 displays the prompt text and flashes the screen at a predetermined frequency, and the sound 3 plays the announcement. The combination of the two provides a prompt, thereby increasing the reminder effect.

[0040] Secondly, the display module 2 is composed of several LED display light modules 21 arranged in a matrix. Therefore, compared with a whole screen, only the damaged LED display light modules 21 need to be replaced, and the maintenance cost in the later stage is relatively low.

[0041] As a further embodiment of this utility model, combined with Figures 1-3 It is known that the embodiment also includes an outer frame 4 and a back plate 5, and a baffle plate 42 is fixedly provided on the front of the outer frame 4;

[0042] A positioning rod 421 is symmetrically fixed on the baffle 42, and an installation hole for inserting the positioning rod 421 is opened on the aluminum mounting frame 1.

[0043] The back plate 5 is fixedly installed on the port of the outer frame 4 on the side opposite to the baffle plate 42, and the aluminum mounting frame 1 is fixed by the positioning screws passing through it and the screw holes on the end face of the positioning rod 421.

[0044] Specifically, the aluminum mounting frame 1 is pushed into the outer frame 4 by the positioning rod 421 inserted into the mounting hole, causing the aluminum mounting frame 1 to abut against the baffle 42. Then, the back plate 5 is pushed into the port on the back of the outer frame 4. Then, the positioning screws cooperate with the positioning rod 421, and the positioning screws are inserted through the through holes opened diagonally on the back of the outer frame 4 and into the screw mounting holes inside the outer frame 4 to fix it, thus achieving the fixation of the back plate 5.

[0045] Furthermore, a fixing rod 43 is welded onto the outer frame 4. The digital smart screen can be fixedly installed by using expansion screws to attach it to the fixing rod 43.

[0046] As a further embodiment of this utility model, combined with Figures 1-3 As can be seen, the display module 2 also includes a wiring board 22, which has mounting holes 23 for mounting each LED display module 21. Furthermore, wiring terminals 231 symmetrically arranged with respect to each mounting hole 23 are fixedly mounted on one side of the wiring board 22. Additionally, a plug-in portion 211 is fixedly mounted on the LED display module 21, and the plug-in portion 211 has plug ports for inserting the wiring terminals 231.

[0047] Specifically, in combination Figure 4 and Figure 6 As can be seen, the terminal 231 in the embodiment includes a terminal post 232 disposed on its end face, and the terminal post 232 is connected to a retaining spring 233 disposed inside the terminal 231. Furthermore, in the default state of the retaining spring 233, the terminal post 232 is positioned at its maximum exposed length within the terminal 231.

[0048] When the LED display module 21 is Figure 4 When inserted downwards from the indicated position, terminal 231 enters the mounting hole 23, and then is inserted into the plug-in port. At this time, the terminal post 232 abuts against the spring in the plug-in port. The terminal post 232 is then compressed and retracted into terminal 231. In this embodiment, the two symmetrically arranged springs are connected to the live wire and neutral wire of the LED display module 21, respectively.

[0049] As another embodiment further provided by this utility model, combined with Figures 1-3 It can be seen that the wiring board 22 has guide posts 24 symmetrically arranged with respect to the mounting holes 23 on one side opposite to the terminal block 231. Secondly, the plug-in part 211 extends to the outer wall of the wiring board 22 on the side opposite to the terminal block 231 and has a U-shaped groove 212 that is at the same level as the end face of the guide post 24.

[0050] Furthermore, the above embodiments also include C-shaped positioning plates 25, which are inserted into the guide post 24 and the U-shaped groove 212 to fix the insertion part 211.

[0051] Specifically, in the above embodiment, a rubber sleeve 251 is slidably disposed on the C-shaped positioning plate 25, which is in a plug-in engagement with the guide post 24. The rubber sleeve 251 is a PP elastic rubber part with a wall thickness of 0.2-0.4 cm. After the terminal 231 is plugged into the plug port on the plug-in part 211, the loop 212 of the terminal 231 is at the same level as the end face of the guide post 24. At this time, the C-shaped positioning plate 25 made of rigid polyethylene plastic is inserted into the loop 212, and then the rubber sleeve 251 is pressed, so that the rubber sleeve 251 is fitted onto the guide post 24.

[0052] Combination Figure 5 It is understood that each plug part 211 in the embodiment needs to be limited by two C-shaped positioning plates 25 inserted into the groove 212 to prevent the plug part 211 from falling out of the mounting hole 23.

[0053] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
