Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a charging pile for passenger station vehicles. Background Technology

[0002] With the rapid development of the new energy vehicle industry and the continuous advancement of electrification transformation in the public transportation sector, the demand for supporting charging facilities at passenger stations, as urban transportation hubs, is increasing day by day. In order to adapt to the centralized and high-frequency charging characteristics of passenger vehicles and improve the operational efficiency and service capabilities of stations, building intelligent and highly reliable charging infrastructure has become a key link in the green development of passenger transportation. According to CN214492576U, a charging pile with heat dissipation and anti-theft functions is disclosed. This technology discloses a technical solution including "a charging pile body and a base; the base has vents arranged in a rectangular array on both the front and rear sides, a wireless transceiver module is fixed inside the lower side of the base, and grounding screws are threaded through the left and right ends of the base; the charging pile body is inserted into the upper end of the base at its lower end, vents are provided on both the front and rear sides of the upper end of the charging pile body, vents are arranged in a linear array on the lower side of the charging pile body, a fan is fixed on the lower side of the charging pile body, the fan is located directly below the vents, and side shells are fixed on both the left and right sides of the charging pile body". It has the technical effects of "ventilating the inside of the charging pile and avoiding direct sunlight, thereby dissipating heat from the charging pile, and also preventing the grounding screws from being pulled out after the charging pile is installed, thus preventing the charging pile from being stolen". During long-term use, existing outdoor charging piles at passenger stations are prone to dust accumulation because their heat dissipation and ventilation structures are directly connected to the external environment. Suspended particulate matter such as dust and willow catkins can easily penetrate into the equipment with natural airflow and adhere to the surfaces of circuit boards and power components. At the same time, moisture and condensation in outdoor rain and snow can also easily seep in through the heat dissipation channels, mixing with the accumulated dust to form conductive dirt. This gradually leads to problems such as decreased insulation performance of components, oxidation of contact points, and local short circuits, ultimately resulting in reduced stability and shortened lifespan of the charging piles under complex outdoor conditions. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this utility model provides a charging pile for passenger station vehicles. By simultaneously opening and closing multiple louvers, it enhances heat dissipation and ensures safety during charging, and provides dust and moisture protection when idle, thereby improving the reliability, protection, and service life of the equipment in outdoor environments.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle charging pile for passenger stations, comprising a base, on which a charging pile is mounted for vehicle charging, the charging pile comprising: The main component includes a charging terminal fixed to the upper part of the base, with a first side door hinged to the left end of the charging terminal; The adjustment assembly includes a frame fixed to the inner wall of the first side door. Several louvers are arranged equidistantly inside the frame, and the two ends of the louvers are rotatably mounted to the inner walls of the two ends of the frame. A shaft frame is fixed in the middle of the inner wall of the louvers, and a bushing is pivotally connected to the shaft frame. The same connecting rod is installed between several bushings. A first mounting bracket is fixed to one end of the frame. A servo motor is installed on the outer wall of the first mounting bracket and is used to drive one of the louvers to rotate.

[0005] Preferably, the adjustment assembly further includes a knob bolt threaded onto the bushing and used to secure the bushing to the connecting rod.

[0006] Preferably, the adjustment assembly further includes a second mounting bracket fixed to one end of the frame. The second mounting bracket has an arc-shaped groove inside. One end of a louver is fixed with a swing arm, and the other end of the swing arm is rotatably mounted with a pulley and located inside the arc-shaped groove.

[0007] Preferably, the adjustment assembly further includes an outer side plate fixed inside the frame at the outer end, the outer side plate having a plurality of louvered holes inside, and a dustproof net installed inside the outer side plate.

[0008] Preferably, the main component further includes a second side door hinged to the right end of the charging terminal, and a plurality of cooling fans are installed on the inner wall of the second side door.

[0009] Preferably, the outer side plate and the dustproof net are provided with mounting holes at the four corners inside, and are fixed with bolts. Beneficial effects

[0010] This utility model provides a vehicle charging station. Compared with the prior art, it has the following advantages: 1. The servo motor drives one of the louvers to rotate. The rotation of the louver is transmitted to the connecting rod through a bushing fixed on its shaft. Since all louvers are connected to the same connecting rod through their respective bushings, the single rotation output of the servo motor is synchronously transmitted to all louvers, thereby achieving uniform adjustment of the opening and closing angle of all louvers. When the charging pile is charging and generates a lot of heat, the louvers open to enhance ventilation and heat dissipation, ensuring that the internal components of the charging terminal are maintained at a safe temperature. When the charging pile is idle, the louvers close to effectively block the entry of external dust, moisture and other foreign objects, improving the long-term operational reliability, protection level and service life of the charging pile in the complex environment of outdoor passenger stations.

[0011] 2. When it is necessary to adjust the initial angle of the louvers or to perform system calibration and maintenance, the knob bolt can be loosened to allow the bushing to rotate or slide freely on the connecting rod, thereby independently adjusting the angle position of the louvers; after adjusting to the target position, tighten the knob bolt, and the tightening force generated at its end will press the bushing and connecting rod together and fix them in place.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0015] Please see Figure 1 - Figure 5 This utility model provides a technical solution: a vehicle charging pile for a passenger station, including a base 1, on which a charging pile 2 is installed for vehicle charging, the charging pile 2 including: The main component 21 includes a charging terminal 211 fixed to the upper end of the base 1, and a first side door 212 is hinged to the left end of the charging terminal 211. The adjustment assembly 22 includes a frame 221 fixed to the inner wall of the first side door 212. Several louvers 222 are arranged equidistantly inside the frame 221, and the two ends of the louvers 222 are rotatably mounted to the inner walls of the two ends of the frame 221. A shaft frame 223 is fixed in the middle of the inner wall of the louvers 222, and a bushing 224 is pivotally connected to the shaft frame 223. The same connecting rod 225 is installed between the several bushings 224. A first mounting bracket 227 is fixed to one end of the frame 221. A servo motor 228 is installed on the outer wall of the first mounting bracket 227 and is used to drive one of the louvers 222 to rotate.

[0016] In this embodiment, the output of the servo motor 228 drives one of the louvers 222 to rotate. The rotational motion of the louver 222 is transmitted to the connecting rod 225 through the bushing 224 fixed on its shaft frame 223. Since all the louvers 222 are connected to the same connecting rod 225 through their respective bushings 224, the single rotational output of the servo motor 228 is synchronously transmitted to all the louvers 222, thereby achieving uniform adjustment of the opening and closing angle of all the louvers 222. When the charging pile 2 is charging and generates a lot of heat, the louvers 222 open to enhance ventilation and heat dissipation, ensuring that the internal components of the charging terminal 211 are maintained at a safe temperature. When the charging pile is idle, the louvers 222 are closed to effectively block the entry of external dust, moisture and other foreign objects, improving the long-term operational reliability, protection level and service life of the charging pile 2 in the complex environment of the outdoor passenger station.

[0017] Specifically, the adjustment assembly 22 also includes a knob bolt 226 threaded onto the bushing 224 and used to secure the bushing 224 to the connecting rod 225.

[0018] In this embodiment, when it is necessary to adjust the initial angle of the louver 222 or to perform system calibration and maintenance, the knob bolt 226 can be loosened so that the bushing 224 can rotate or slide freely on the connecting rod 225, thereby independently adjusting the angle position of the louver 222; after adjusting to the target position, the knob bolt 226 is tightened, and the fastening force generated at its end presses the bushing 224 and the connecting rod 225 together and fixes them.

[0019] Specifically, the adjustment component 22 also includes a second mounting bracket 229 fixed to one end of the frame 221. The second mounting bracket 229 has an arc-shaped slide groove 2210 inside. One end of a louver 222 is fixed with a swing arm 2211, and the other end of the swing arm 2211 is rotatably mounted with a pulley 2212 and located inside the arc-shaped slide groove 2210.

[0020] In this embodiment, when the louver 222 rotates, the swing arm 2211 fixed to one end of the louver 222 swings accordingly, causing the pulley 2212 at its end to roll along the arc-shaped groove 2210 on the second mounting frame 229; thereby guiding and constraining the rotation of the louver 222.

[0021] Specifically, the adjustment component 22 also includes an outer side plate 2213 fixed inside the outer end of the frame 221. The outer side plate 2213 has several louvered holes 2214 inside and a dustproof net 2215 installed inside the outer side plate 2213.

[0022] In this embodiment, when the louvered plate 222 is turned on for heat dissipation, the louvered holes 2214 on the outer plate 2213 guide the cooling airflow in at a specific angle, while effectively blocking most of the splashing rainwater and larger foreign objects through physical shielding; subsequently, when the airflow passes through the inner dustproof net 2215, its dense mesh structure can further intercept fine suspended particles such as dust and willow catkins.

[0023] Specifically, the main component 21 also includes a second side door 213 hinged to the right end of the charging terminal 211, and a number of cooling fans 214 are installed on the inner wall of the second side door 213.

[0024] In this embodiment, when the charging pile 2 is operating at high power or when the ambient temperature is high, causing internal heat to accumulate, the cooling fan 214 can drive airflow, working in conjunction with the natural ventilation formed by the regulating component 22 to quickly dissipate the heat generated by the core power components inside the charging terminal 211.

[0025] Specifically, mounting holes are provided at the four corners of the outer side panel 2213 and the dustproof net 2215, and they are fixed with bolts.

[0026] In this embodiment, the dustproof net 2215, which needs to be cleaned or replaced regularly, can be disassembled and installed.

[0027] The working principle and usage process of this utility model are as follows: First, when the vehicle starts charging, the charging terminal 211 enters a high-power operation state, and the internal components generate a lot of heat. At this time, the cooling fan 214 forces the internal air to flow. At the same time, the output end of the servo motor 228 drives one of the louvers 222 to rotate. The rotational motion of the louver 222 is transmitted to the connecting rod 225 through the bushing 224 fixed on its shaft frame 223. Since all the louvers 222 are connected to the same connecting rod 225 through their respective bushings 224, the single rotational output of the servo motor 228 is synchronously transmitted to all the louvers 222, thereby realizing the opening of all the louvers 222. External cooling air then passes sequentially through the louvers 2214 with a specific angle on the outer side panel 2213 and the dust filter 2215 on the inner side. After the louvers 2214 block most of the rainwater and larger foreign objects, and the dust filter 2215 filters fine dust particles, the clean cooling airflow enters the equipment and works in conjunction with the forced airflow formed by the cooling fan 214 to efficiently dissipate the accumulated heat and ensure that the equipment temperature remains stable within a safe range. When charging is finished or the device enters standby mode, the servo motor 228 runs in reverse, driving the louver 222 to close synchronously. The tightly closed louver 222 prevents the intrusion of external dust, moisture and foreign objects.
