Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic bus stop sign technology, and in particular relates to an electronic bus stop sign. Background Technology
[0002] Electronic bus stop signs are an important component of modern urban public transportation systems. Using GPS positioning and communication technology, they display real-time bus arrival information. These signs not only provide arrival times but also offer multimedia video playback and real-time video monitoring, enhancing the passenger waiting experience. Furthermore, they can display weather forecasts, news, and other convenient information, making bus stops more intelligent and user-friendly. The application of electronic bus stop signs demonstrates the technological advancements and humanistic care in urban traffic management.
[0003] In traditional bus stop designs, electronic signs are typically used to provide passengers with real-time bus information. However, electronic signs generally suffer from poor heat dissipation; prolonged operation of the internal displays can lead to heat buildup, affecting the normal operation of the displays, extending the equipment's lifespan, and increasing maintenance costs. Utility Model Content
[0004] The purpose of this invention is to provide an electronic bus stop sign to solve common problems such as poor heat dissipation of electronic bus stop signs.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: it includes an outer shell and two glass doors. The top of the inner side of the outer shell is provided with a lighting lamp. An electronic display screen and a paper display board are respectively provided on the inner side of the two glass doors. The electronic display screen and the paper display board are both connected to the outer shell through a bracket. A cooling radiator is provided between the electronic display screen and the paper display board. Cooling frames are provided on both sides of the outer shell and are connected by screws. Heat sinks are provided in both cooling frames.
[0006] Furthermore, the radiator includes a water tank with several heat-conducting holes running through it. Several heat-conducting rods are provided on both sides of the water tank and connected by a sealing element. A water pump is provided at the top of the water tank, and the input end of the water pump is inserted into the inside of the water tank. A support frame is provided at the bottom of the water tank, and the support frame is connected to the water tank and the outer shell by screws.
[0007] Furthermore, the heat sink includes a heat dissipation trough, and several heat dissipation fins are installed on the side of the heat dissipation trough. The heat dissipation trough is connected to the outer casing by screws.
[0008] Furthermore, the water pump output end is provided with a first tee pipe, and the two ends of the first tee pipe are respectively connected to the upper part of the heat dissipation water tank on both sides through pipe fittings.
[0009] Furthermore, a second tee pipe is provided below the first tee pipe, and the right-angle head of the second tee pipe is connected to the water tank. The two ends of the second tee pipe are respectively connected to the lower part of the heat dissipation water tank on both sides through pipe fittings.
[0010] Furthermore, dustproof nets are provided on both sides of the cooling frame and connected by buckles.
[0011] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: This invention employs a radiator, heat sink, and coolant circulation system to effectively solve the problem of heat buildup during long-term operation of electronic bus stop signs. The coolant in the water tank absorbs the heat generated by the electronic display screen, and then a water pump and T-pipe circulate the coolant to a cooling water tank for further dissipation. This significantly improves heat dissipation efficiency, ensures the normal operation of the electronic display screen, and prevents equipment failure due to overheating. Attached Figure Description

Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0015] Combination Figs. 1 to 4The electronic bus stop sign shown includes an outer casing 1 and two glass doors 2. An inner top light 11 is provided on the inner side of the outer casing 1. An electronic display screen 3 and a paper display board 4 are respectively provided on the inner side of the two glass doors 2. The electronic display screen 3 and the paper display board 4 are both connected to the outer casing 1 by a bracket. A cooling radiator 5 is provided between the electronic display screen 3 and the paper display board 4. Cooling frames 6 are provided on both sides of the outer casing 1 and are connected by screws. Heat sinks 7 are provided in both cooling frames 6.
[0016] The radiator 5 includes a water tank 51 with several heat-conducting holes 52. When hot air passes through the heat-conducting holes 52, the heat is transferred to the coolant in the water tank 51 to improve the heat absorption efficiency. Several heat-conducting rods 53 are provided on both sides of the water tank 51 and connected by a sealing element to facilitate the transfer of heat from the outside of the water tank 51 to the coolant through the heat-conducting rods 53. A water pump 54 is provided on the top of the water tank 51 and the input end of the water pump 54 is inserted into the inside of the water tank 51 for circulating the coolant. A support frame 55 is provided at the bottom of the water tank 51 and is connected to the water tank 51 and the outer shell 1 by screws.
[0017] The heat sink 7 includes a heat sink 71, in which the coolant circulates between the heat sink 71 and the water tank 51 to absorb and dissipate heat from the bus stop sign. Several heat dissipation fins 72 are installed on the side of the heat sink 71 to increase the heat dissipation area and improve the heat dissipation efficiency. The heat sink 71 is connected to the outer casing 1 by screws.
[0018] The output end of the water pump 54 is provided with a first tee pipe 56. The two ends of the first tee pipe 56 are connected to the upper part of the heat dissipation water tanks 71 on both sides through pipe fittings. The water pump 54 delivers the hotter coolant in the upper part of the water tank to the heat dissipation water tank 71 through the first tee pipe 56 for heat dissipation. The cooled coolant sinks to the lower part of the heat dissipation water tank 71.
[0019] Below the first tee pipe 56, there is a second tee pipe 57. The right-angle head of the second tee pipe 57 is connected to the water tank 51. Both ends of the second tee pipe 57 are connected to the lower part of the heat dissipation water tanks 71 on both sides through pipe fittings. The coolant that has completed the cooling returns to the water tank 51 through the second tee pipe 57.
[0020] Dustproof nets are provided on both sides of the cooling frame 6 and connected by buckles to prevent dust from entering the device while also allowing airflow to pass through and carry away the heat from the heat sink 72.
[0021] Working principle: When this utility model is in use, the electronic display screen 3 generates heat during operation. When hot air passes through the heat conduction hole 52, the heat is transferred to the coolant in the water tank 51. At the same time, the heat conduction rod 53 conducts the heat outside the water tank 51 to the coolant. After the hot coolant rises, the water pump 54 transports the hotter coolant in the upper part of the water tank to the heat dissipation tank 71 through the first three-way pipe 56. The coolant is then dissipated through the heat dissipation fins 72. After cooling, the coolant sinks to the lower part of the heat dissipation tank 71 and returns to the water tank 51 through the second three-way pipe 57. This prevents dust from entering the device and also allows airflow to pass through and carry away the heat from the heat dissipation fins 72.
