Description

Technical Field

[0001] This utility model relates to a wide range of applications, specifically a large-size ultra-thin electronic bus stop sign. Background Technology

[0002] Ultra-thin electronic bus stop signs are products that apply electronic display technology to public transportation stations, commercial billboards, and other fields. Currently, most electronic bus stop signs on the market are quite thick and heavy, resulting in low space utilization, high screen heat generation, and poor heat dissipation. Furthermore, existing electronic bus stop signs often use gas struts for their access doors. This installation not only increases the maintenance costs of the gas struts but also limits the opening angle of the door, especially towards the top where space becomes increasingly limited, making installation more difficult.

[0029] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0030] Please see Figures 1-2 A large-size ultra-thin electronic bus stop sign includes a main body 1, a first inspection door 10, a second inspection door 13, a screen 19, and an electrical installation area. The bottom of the main body 1 is provided with a mounting base 2, which adopts a double-base fixing plate structure with reinforcing ribs between the double-base fixing plates. The front side of the main body 1 is provided with a front panel 3, the top of the main body 1 is provided with a lifting lug 5, the upper parts of both sides of the main body 1 are provided with speaker holes 6, and the lower part of the speaker holes 6 is provided with a light strip 7. The upper part of the front panel 3 is provided with a first camera 4. The first inspection door 10 is located on the rear side of the main body 1, and the second inspection door 13 is located below the first inspection door 10 and is installed on the main body 1.

[0031] like Figures 1-4 As shown, the upper part of the first inspection door 10 is provided with an exhaust louver 15, and the first inspection door 10 is provided with a rear panel 17. The rear panel 17 is fixed to the first inspection door 10 by waterproof bolts. A waterproof strip is provided between the first inspection door 10 and the rear panel 17. Waterproof installation measures, such as sealing rings, are also adopted between the main body 1 and the first inspection door 10.

[0032] An exhaust fan 8 is provided on the rear side of the exhaust louver 15, and a second camera 14 is provided on the rear panel 17 below the exhaust fan 8. A blank area 9 is reserved on the rear panel 17 for displaying screen content.

[0033] See figure Figure 2 , Figure 5 , Figure 6 , Figure 7The second inspection door 13 is provided with an air inlet louver 16. A baffle 12 is provided on the rear side of the air inlet louver 16 and is inclined upward. An air inlet filter cotton 11 is also provided between the baffle 12 and the air inlet louver 16. An air inlet fan 21 is provided on the baffle 12. The baffle 12 can be used to fix the air inlet fan 21 and the air inlet filter cotton 11. In this embodiment, the air inlet filter cotton 11 is G4 filter cotton.

[0034] Both the first inspection door 10 and the second inspection door 13 are equipped with access control devices, so that the number of times the electronic bus stop sign is opened for normal maintenance will be recorded.

[0035] Both the intake fan 21 and the exhaust fan 8 are inclined. In this embodiment, in order to achieve the best performance, the inlet fan 21 and the exhaust fan 8 are inclined at an angle of 45°. Five exhaust fans 8 are fixed on the top of the first maintenance door 10, and the airflow at the inlet and outlet is completely separated to achieve the function of hot and cold air separation. Hot airflow will not flow back into the electronic bus stop sign. When maintenance is required, the fan and the maintenance door are opened together, making replacement and maintenance very convenient.

[0036] like Figure 2 As shown, the screen 19 is located in the middle of the main body 1, and the electrical installation area is below the screen 19. The screen 19 is installed in the main body 1 by the screen fixing member 20. An LED strip screen 18 is provided above the screen 19. The LED strip screen 18 is used to display short information, such as station name or floor information.

[0037] Hinges 26 are provided on both the screen 19 and the main body 1 on the side of the electrical installation area. The first inspection door 10 and the second inspection door 13 are both installed on the main body 1 through the hinges 26, so that the first inspection door 10 and the second inspection door 13 can be opened in a side-opening manner, which not only facilitates installation and maintenance, but also reduces manufacturing costs. In this embodiment, the hinge is a CL138 hinge, and the hinge 26 is installed in a hidden manner, which makes the overall appearance of the product more integrated.

[0038] See Figure 2 , Figure 8 and Figure 9 The electrical installation area includes an air switch 25, a surge protector 24, a DC power supply 23, a cable tray 22, a motherboard (including a central controller, etc.), and a hard drive, etc. In addition, the electronic bus stop sign also houses electronic components such as a temperature sensor, access control system, water immersion sensor, speaker, and 4G router; see reference... Figure 8-9 After the power supply is connected to the air switch 25, surge protector 24 and electricity meter, the switching power supply is connected to convert AC 220V to DC 24V and DC 12V to the central controller, which are then connected to the screen 19, intake fan 21, exhaust fan 8, access control, temperature sensor, water immersion sensor, power amplifier, front and rear cameras, 4G router, etc.

[0039] In this embodiment, as Figure 10 As shown, the electronic bus stop sign has reached a minimum thickness of 100mm, with the screen occupying 43mm and a 13mm space reserved in front of the screen for heat dissipation; screen 19 is a 55-inch LCD screen.

[0040] During normal operation, the screen displays a pre-defined image after power is connected. A temperature sensor monitors temperature changes in real time, and the fan activates when the temperature exceeds 40°C. The camera monitors the area within its field of view in real time and uploads the data to the cloud and stores it on the hard drive. If the water immersion sensor detects water entering, it will issue a warning and cut off the power based on the water level. When maintenance personnel open the access door, the access control sensor will also trigger an alarm and upload alarm information and monitoring video.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
