Description
Technical Field
[0001] This utility model relates to the technical field of bus stop advertising display screens, specifically an advertising display screen for bus stops. Background Technology
[0002] In modern bus shelters, electronic displays have become standard equipment. They display real-time arrival times and route information for various buses. Passengers can simply stand under the shelter to clearly see the location and estimated arrival time of their bus, eliminating the need to anxiously look around. This precise information display greatly saves passengers' time and makes travel planning more relaxed. In addition, when no one is standing in front of the electronic display to inquire about information, the display can automatically switch to advertising mode to play advertisements.
[0003] Bus stop electronic displays operate for extended periods, thus requiring effective heat dissipation. Most existing displays rely on cooling fans, which are less effective in summer, hindering stable operation. Therefore, to further improve heat dissipation in summer, this paper proposes an advertising display screen for bus stops. Utility Model Content

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.

The housing component 1 includes a housing body 101, an installation compartment 102, a transparent window 103, an inspection door 104, and a concave heat exchange compartment 105.
[0034] The installation compartment 102 is formed in the middle of the outer shell body 101 and extends through the front and rear ends of the outer shell body 101. The transparent window 103 and the maintenance door 104 are respectively installed on the inner side of the front end and the inner side of the rear end of the installation compartment 102. The maintenance door 104 is movably connected to the outer shell body 101 through a hinge.
[0035] The concave heat exchange chamber 105 is formed inside the mounting chamber 102 and distributed on the outside of the mounting chamber 102. The concave heat exchange chamber 105 penetrates the top of the outer shell body 101.
[0036] An active heat dissipation component 2 is installed on the inspection door 104. The active heat dissipation component 2 is used to perform daily heat dissipation operation on the electronic display screen 5.
[0037] An auxiliary heat dissipation component 3 is provided inside the concave heat exchange chamber 105 and on the top of the outer shell body 101. The auxiliary heat dissipation component 3 uses rainwater to provide auxiliary heat dissipation for the interior of the installation chamber 102.
[0038] The bottom of the outer shell 101 is also provided with a water replenishment component 4 that extends into the concave heat exchange chamber 105. The water replenishment component 4 is used to replenish water to the inside of the concave heat exchange chamber 105 when there is insufficient rainwater.
[0039] The auxiliary heat dissipation component 3 includes concave heat dissipation fins 301, a water receiving basin 302, and a filter screen 303;
[0040] The water receiving hopper 302 is fixed to the top of the outer shell body 101, the filter screen cover 303 is fixed to the top of the water receiving hopper 302, and the inner side of the water receiving hopper 302 is connected to the inner side of the concave heat exchange chamber 105.
[0041] Concave heat dissipation fins 301 are distributed inside the concave heat exchange chamber 105 and extend through to the inside of the mounting chamber 102;
[0042] The water collection hopper 302 and filter screen 303 are used to collect and filter rainwater. The rainwater enters the concave heat exchange chamber 105 and exchanges heat with the air inside the installation chamber 102 through the concave heat dissipation fins 301.
[0043] Multiple concave heat dissipation fins 301 are evenly arranged along the horizontal longitudinal direction, and the bottom of the concave heat dissipation fins 301 does not contact the bottom of the inner wall of the concave heat exchange chamber 105.
[0044] The active cooling component 2 includes louvers 201, a cooling fan 202, and a filter 203;
[0045] The inner cavity of the louver 201 and the filter 203 is installed inside the inspection door 104, and the louver 201 is distributed above the filter 203;
[0046] The cooling fan 202 is installed at one end of the access door 104 near the inside of the installation compartment 102 and aligned with the position of the louver 201.
[0047] The cooling fan 202 operates to exhaust hot air inside the mounting chamber 102 through the louvers 201, and the filter 203 is used to filter the air entering the mounting chamber 102.
[0048] In this embodiment: When this advertising display screen is in use, the electronic display screen 5 can display the arrival time and route information of each bus in real time. When no one is standing at the front of the outer shell 101, the electronic display screen 5 automatically switches to the advertising playback mode. It should be noted that the above functions are conventional functions of existing bus stop display screens and have been widely used in the field of bus stops. Therefore, they will not be described in detail here.
[0049] The electronic display screen 5 generates a lot of heat when it is running, which will raise the internal temperature of the mounting chamber 102. When the temperature sensor inside the mounting chamber 102 detects that the temperature exceeds the set temperature, it controls the start of the cooling fan 202. The cooling fan 202 exhausts the hot air inside the mounting chamber 102 through the louvers 201, and the outside air enters the mounting chamber 102 after being filtered by the filter 203. This process is repeated to achieve the internal cooling operation of the mounting chamber 102.
[0050] In addition, when it rains, rainwater that comes into contact with the filter screen 303 can be filtered by the filter screen 303 and enter the water receiving hopper 302, and eventually flow into the concave heat exchange chamber 105 for collection. When the electronic display screen 5 is running, the hot air inside the mounting chamber 102 can exchange heat with the water inside the concave heat exchange chamber 105 through the concave heat dissipation fins 301, thereby achieving an auxiliary cooling effect. This function is very suitable for heat dissipation in summer and can provide good conditions for the electronic display screen 5 to maintain stable operation in summer.

[0052] The water inlet pipe 401 is buried below ground and extends from the bottom of the mounting foot of the outer shell 101 to the inside of the outer shell 101. The solenoid valve 402 is distributed inside the mounting foot of the outer shell 101 and fixed at the top of the water inlet pipe 401. The output end of the solenoid valve 402 extends into the concave heat exchange chamber 105.
[0053] A liquid level sensor is installed inside the concave heat exchange chamber 105, and the solenoid valve 402 and the liquid level sensor are electrically connected to the controller installed inside the installation chamber 102 via wires.
[0054] In this embodiment: the water level inside the concave heat exchange chamber 105 can be monitored by a liquid level sensor. When the weather is hot and there is too little water inside the concave heat exchange chamber 105 to achieve a good auxiliary heat dissipation effect, the solenoid valve 402 is opened by controlling it. At this time, supplementary water can be delivered into the concave heat exchange chamber 105 through the water inlet pipe 401, so as to keep the concave heat dissipation fins 301 in good heat dissipation effect.
[0055] It should be noted that the water supplied by the inlet pipe 401 to the concave heat exchange chamber 105 can be recycled water, for example, by connecting the inlet pipe 401 to a nearby recycled water network.

[0057] The outer walls of the main body 101 are formed with guide grooves 107 on both sides. The top of the guide grooves 107 is connected to both ends of the overflow port 106. The guide grooves 107 extend to the bottom of the mounting feet of the main body 101 and are inclined towards the rear end of the main body 101.
[0058] In this embodiment: when encountering heavy rain, if too much rainwater is collected inside the concave heat exchange chamber 105 and the water level reaches the height of the overflow port 106, the excess rainwater can be discharged through the overflow port 106 and flow downward along the trajectory of the guide channel 107, and flow to the road surface in the direction of the rear end of the outer shell 101.
