Technical Field

[0001] This utility model relates to the field of road sign technology, and in particular to an electronic road sign. Background Technology

[0002] The electronic bus route sign mainly consists of an LED dot-matrix display screen, a control module, a drive module, and a communication port. In use, the content to be displayed is first programmed into a computer, then sent to the route sign via a dedicated communication controller. The sign then automatically displays the user-edited content. The entire process is convenient and fast. Located on the center of both sides of the bus, it achieves redundant display in multiple positions.

[0003] In existing technology, electronic bus route signs are usually installed at both ends of the bus and on the side of the bus that is the same as the boarding and alighting doors, so that passengers can see the bus route information when waiting for the bus and getting on and off the bus. However, since the bus body is usually long, when multiple buses are queuing to enter the station, the bus route signs located between the buses in front and behind can be blocked, which can make it difficult for passengers in front of and behind the bus to see them in time, resulting in passengers not being able to board the bus in time and affecting their travel. In addition, the display screen is usually fixed to the route sign plate with multiple bolts. Once the display screen malfunctions and needs to be disassembled and repaired, many bolts need to be removed and installed, making disassembly and maintenance cumbersome. Utility Model Content

[0029] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0030] like Figure 1-6 As shown, this embodiment includes a concave frame 1 and a road sign plate 2. The road sign plate 2 is disposed inside the concave frame 1. The road sign plate 2 has display openings 27 on both the front and back. Each display opening 27 is equipped with a display screen 3. The bottom right end of the concave frame 1 has a mounting groove 4. An AC motor 5 is fixed in the mounting groove 4. The power end of the AC motor 5 is connected to a drive shaft 6. The lower right side of the road sign plate 2 is fixed to the upper end of the drive shaft 6.

[0031] By installing the electronic road sign on the side of the bus, and with a display screen 3 installed at both the front and rear of the road sign panel 2, the drive shaft 6 is rotated forward by the operation of the AC motor 5, which facilitates the quick and easy unfolding of the road sign panel 2. This allows the two display screens 3 to correspond to the front and rear of the bus, respectively, enabling passengers to view the electronic road sign in a timely and intuitive manner, thus ensuring their normal travel.

[0032] like Figure 1 , 6 As shown, in this embodiment, a proximity switch 23 is fixed on the inner right wall of the concave frame 1, and a proximity plate 24 corresponding to the proximity switch 23 is connected to the front right side of the road sign plate 2. The proximity switch 23 is connected to a warning light 25 located outside the concave frame 1 via a wire.

[0033] Furthermore, when the road sign plate 2 is unfolded, it will cause the approach plate 24 to move closer to the proximity switch 23. At this time, the proximity switch 23 senses the activation of the approach plate 24. With the warning light 25 installed in the cab and set to be electrically connected to the proximity switch 23 via a wire, the warning light 25 will light up in the cab. If the driver forgets to put away the road sign plate 2, the warning light 25 will remind the driver to avoid the road sign plate 2 being continuously unfolded during driving, thereby reducing safety hazards.

[0034] like Figure 6 , 9 As shown, in this embodiment, a magnet block 21 is fixed on the left side of the inner rear wall of the concave frame 1, and a magnet piece 22 is magnetically attracted to the front of the magnet block 21. The magnet piece 22 is connected to the back of the road sign board 2.

[0035] When the road sign 2 needs to be retracted into the concave frame 1, the AC motor 5 drives the drive shaft 6 to reverse and reset. Therefore, the drive shaft 6 will retract the road sign 2 into the concave frame 1. At the same time, the proximity plate 24 moves away from the proximity switch 23, and the proximity switch 23 controls the warning light 25 to turn off. This indicates that the road sign 2 has been retracted, so as to prevent the road sign 2 from being continuously unfolded during the journey, thereby reducing safety hazards. When the road sign 2 is retracted into the concave frame 1, the magnet 21 will attract the magnetic iron sheet 22, thus preventing the road sign 2 from being accidentally unfolded during the bus's journey.

[0036] like Figure 2-9As shown, in this embodiment, a lower insert plate 7 is fixed to the lower end of each display screen 3. A slot 12 matching the lower insert plate 7 is opened at the bottom of each display opening 27. Lower latching assemblies are provided on both the left and right sides of the lower insert plate 7. Each lower latching assembly includes a lower spring telescopic rod 9 and a lower locking ball 10. Lower contraction grooves 8 are opened on both the left and right sides of the lower insert plate 7. One end of each lower spring telescopic rod 9 is fixed in the lower contraction groove 8, and each lower locking ball 10 is connected to the other end of the lower spring telescopic rod 9. Lower arc-shaped locking grooves 11 are opened on the left and right ends of the inner wall of the slot 12. The lower locking ball 10 engages with the lower arc-shaped locking groove 11. A connecting block 20 is fixed on both the left and right sides of the bottom of the slot 12. The lower end of the lower insert plate 7 has a left... Both sides of the right side have a docking groove 19, and the docking block 20 is interference-fitted with the docking groove 19. The upper end of the display screen 3 is fixed with an upper insert plate 14. The front and rear parts of the road sign board 2 are opened with an insertion port 13 that communicates with the adjacent display port 27. The upper insert plate 14 is provided with upper buckle assemblies on both the left and right sides. The upper buckle assembly includes an upper spring telescopic rod 16 and an upper locking ball 17. The upper insert plate 14 is opened with an upper shrinkage groove 15 on both the left and right sides. One end of the upper spring telescopic rod 16 is fixed in the adjacent upper shrinkage groove 15, and the upper locking ball 17 is fixed in the other end of the upper spring telescopic rod 16. The inner wall of the insertion port 13 is opened with an upper arc-shaped locking groove 18 on both the left and right sides. The upper locking ball 17 is engaged with the upper arc-shaped locking groove 18.

[0037] When the display screen 3 is installed into the display opening 27 of the road sign board 2, the lower insert plate 7 is simultaneously inserted into the lower slot 12, and the trapezoidal connecting block 20 is connected into the connecting groove 19. Since the connecting block 20 and the connecting groove 19 are interference-fitted, the display screen 3 is prevented from wobbling left and right. Moreover, the lower locking ball 10 is locked into the lower arc-shaped locking groove 11 by the elastic force of the lower spring telescopic rod 9, and the upper locking ball 17 is locked into the upper arc-shaped locking groove 18 by the elastic force of the upper spring telescopic rod 16, which helps to prevent the display screen 3 from loosening. Therefore, the display screen 3 is locked and fixed by the lower locking assembly and the upper locking assembly, eliminating the traditional bolt fixing method, making the installation convenient and quick.

[0038] like Figure 2 , 3 As shown in this embodiment, a pull ring 26 is fixed to the middle of the upper end of the road sign plate 2.

[0039] When the display screen 3 needs to be disassembled for maintenance, pull the display screen 3 upwards using the pull ring 26. During this process, the lower locking ball 10 will compress the lower spring telescopic rod 9 and move the lower locking ball 10 out of the lower arc-shaped locking groove 11. At the same time, the upper locking ball 17 will compress the upper spring telescopic rod 16 and move the upper locking ball 17 out of the upper arc-shaped locking groove 18. Simultaneously, the docking block 20 moves out of the docking groove 19. Then, the upper insert plate 14, the display screen 3, and the lower insert plate 7 move upwards and sequentially move out of the insertion port 13, thereby facilitating convenient and quick disassembly and maintenance of the display screen 3.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementations of this utility model. In addition, other implementations are also included. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
