Description
A Vienna rectifier high-frequency inverter charging pile Technical Field
[0001] This utility model relates to the field of charging pile technology, specifically a Vienna rectifier high-frequency inverter charging pile. Background Technology
[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug for charging electric vehicles. In order to provide stable and efficient power conversion, charging equipment combining Vienna rectification technology and high-frequency inverter technology is used, namely Vienna rectification high-frequency inverter charging piles.
[0003] In actual use, existing charging piles generate heat during operation due to the high-frequency inverter module and Vienna rectifier module. This heat accumulates inside the charging pile's cabinet, and overheating may affect its normal operation and hinder the extension of the equipment's lifespan. In addition, the lack of a protective structure in front of the charging pile makes it susceptible to collisions due to reversing or dark surroundings, resulting in damage to the charging pile and losses for the user. Summary of the Invention
[0004] This invention provides a Vienna rectifier high-frequency inverter charging pile, which has the advantages of convenient and efficient heat dissipation and impact protection, thus solving the problems of slow heat dissipation and lack of protective structure in front of existing charging piles.
[0005] To achieve efficient heat dissipation and impact protection, this utility model provides the following technical solution: a Vienna rectifier high-frequency inverter charging pile, comprising a charging pile body and a heat dissipation door hinged to one side edge of the back of the charging pile body, wherein the surface of the heat dissipation door has an installation opening, and further comprising:
[0006] A heat dissipation assembly is installed inside the mounting port, the heat dissipation assembly including an adjustable speed cooling fan, a PLC controller and a temperature sensor;
[0007] Two sets of anti-collision components are installed on the lower front of the charging pile body. The anti-collision components include a damping hydraulic rod, a buffer spring, a metal plate, a buffer rubber pad, and a reflector.
[0008] As a preferred embodiment of this utility model, the heat dissipation assembly includes an adjustable speed cooling fan fixedly connected inside the mounting port. One side of the adjustable speed cooling fan is electrically connected to a PLC controller via a power cord, and one side of the PLC controller is electrically connected to a temperature sensor via a power cord.
[0009] As a preferred embodiment of this invention, the PLC controller is installed on one side of the heat dissipation door, and the temperature sensor is installed inside the charging pile body.
[0010] As a preferred technical solution of this utility model, the charging pile body is equipped with a Vienna rectifier module and a high-frequency inverter module. The output terminal of the Vienna rectifier module is directly connected to the input terminal of the high-frequency inverter module through a DC bus capacitor.
[0011] As a preferred embodiment of this utility model, the anti-collision component includes two damping hydraulic rods fixedly connected to the lower front of the charging pile body. A buffer spring is sleeved on the surface of the damping hydraulic rod, and a metal plate is fixedly connected to one end of the damping hydraulic rod and the buffer spring.
[0012] As a preferred embodiment of this utility model, a buffer rubber pad is fixedly connected to one side of the metal plate, and a reflector is fixedly connected to one side of the buffer rubber pad.
[0013] As a preferred embodiment of this utility model, a protective frame is welded to the outside of the heat dissipation door, and a dustproof net is fixedly installed on the surface of the protective frame.
[0014] As a preferred technical solution of this utility model, one edge of the charging pile body is fixedly connected to a limiting member, and the limiting member has the charging gun wire of the charging pile body snapped into it.
[0015] Compared with the prior art, this utility model provides a Vienna rectifier high-frequency inverter charging pile, which has the following beneficial effects:
[0016] 1. This Vienna rectifier high-frequency inverter charging pile can automatically activate an adjustable-speed cooling fan by setting up a heat dissipation component, thereby improving heat dissipation efficiency. During use, a temperature sensor monitors the internal temperature of the charging pile. If the temperature exceeds the preset temperature threshold for automatically activating the adjustable-speed cooling fan, the temperature sensor sends a signal to the PLC controller. The PLC controller then controls the adjustable-speed cooling fan to activate, allowing it to dissipate heat from the inside of the charging pile and expel the heat to the outside. This ensures efficient heat dissipation and prevents heat from accumulating inside the charging pile's cabinet. Overheating could affect its normal operation and help extend the equipment's lifespan.
[0017] 2. This Vienna rectifier high-frequency inverter charging pile can be protected by anti-collision components. During use, the damping hydraulic rod has a certain length, separating the charging pile from the vehicle. If it is impacted due to improper operation, the damping hydraulic rod is subjected to external force, the inner rod contracts inward, and the internal piston drives the fluid flow. The resistance generated during the fluid flow slows down the piston's movement, reducing the transmission of impact force from the vehicle. The buffer spring has elastic potential energy, allowing it to return to its original shape after the impact force disappears. Simultaneously, the reflector serves as a warning at night, preventing collisions with the charging pile due to reversing or dark surroundings, thus avoiding damage to the charging pile and losses for the user. This contributes to the protection of the charging pile. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0024] Please refer to Figures 1-4. This utility model discloses a Vienna rectifier high-frequency inverter charging pile, including a charging pile body 1 and a heat dissipation door 2 hinged to one edge of the back of the charging pile body 1. The surface of the heat dissipation door 2 has an installation opening, and it also includes:
[0025] The heat dissipation component 3 is installed inside the installation port. The heat dissipation component 3 includes an adjustable speed cooling fan 301, a PLC controller 302 and a temperature sensor 303.
[0026] Two sets of anti-collision components 4 are installed on the lower front of the charging pile body 1. The anti-collision components 4 include a damping hydraulic rod 401, a buffer spring 402, a metal plate 403, a buffer rubber pad 404, and a reflector 405.
[0027] Specifically, the heat dissipation component 3 includes an adjustable speed cooling fan 301 fixedly connected inside the mounting port. One side of the adjustable speed cooling fan 301 is electrically connected to a PLC controller 302 via a power cord, and one side of the PLC controller 302 is electrically connected to a temperature sensor 303 via a power cord.
[0028] In this embodiment, during use, the temperature sensor 303 monitors the temperature inside the charging pile. If the temperature is higher than the preset temperature threshold for automatically turning on the adjustable speed cooling fan 301, the temperature sensor 303 sends a signal to the PLC controller 302, which then controls the adjustable speed cooling fan 301 to turn on, allowing the adjustable speed cooling fan 301 to dissipate heat from the inside of the charging pile.
[0029] Specifically, the PLC controller 302 is installed on one side of the heat dissipation door 2, and the temperature sensor 303 is installed inside the charging pile body 1.
[0030] In this embodiment, the temperature sensor 303 monitors the temperature inside the charging pile, and the PLC controller 302 facilitates the monitoring of signals and the issuance of operation commands.
[0031] Specifically, the charging pile body 1 is equipped with a Vienna rectifier module 5 and a high-frequency inverter module 6. The output terminal of the Vienna rectifier module 5 is directly connected to the input terminal of the high-frequency inverter module 6 through a DC bus capacitor.
[0032] In this implementation scheme, the Vienna rectifier module 5 and the high-frequency inverter module 6 are used to efficiently convert electrical energy, ensuring the safety and efficiency of the charging process.
[0033] Specifically, the anti-collision component 4 includes two damping hydraulic rods 401 fixedly connected to the lower front of the charging pile body 1. A buffer spring 402 is sleeved on the surface of the damping hydraulic rod 401. A metal plate 403 is fixedly connected to one end of the damping hydraulic rod 401 and the buffer spring 402. A buffer rubber pad 404 is fixedly connected to one side of the metal plate 403. A reflector 405 is fixedly connected to one side of the buffer rubber pad 404.
[0034] In this implementation scheme, through the setting of the anti-collision component 4, the damping hydraulic rod 401 has a certain length during use, which separates the charging pile from the vehicle at a certain distance. If it is hit by the vehicle due to improper operation, the damping hydraulic rod 401 is subjected to external force, the inner rod contracts inward, and the internal piston drives the fluid to flow. The resistance generated during the fluid flow slows down the speed of the piston movement, thus reducing the transmission of the impact force brought by the vehicle. The buffer spring 402 has elastic potential energy, which allows it to return to its original shape after the impact force disappears. At the same time, the reflector 405 can serve as a warning at night.
[0035] Specifically, a protective frame 7 is welded to the outside of the heat dissipation door 2, and a dustproof net 8 is fixedly installed on the surface of the protective frame 7.
[0036] In this implementation plan, the dustproof net 8 is used to reduce the amount of dust entering the charging pile.
[0037] Specifically, one edge of the charging pile body 1 is fixedly connected to the limiting member 9, and the charging gun wire of the charging pile body 1 is snapped into the limiting member 9.
[0038] In this embodiment, by setting the limiting member 9, the power cord of the charging gun can be locked inside after use to fix it and prevent the charging gun from falling.
[0039] The working principle and usage process of this utility model are as follows: During use, the temperature sensor 303 monitors the internal temperature of the charging pile. If the temperature is higher than the preset temperature threshold for automatically turning on the adjustable speed cooling fan 301, the temperature sensor 303 sends a signal to the PLC controller 302. The PLC controller 302 controls the adjustable speed cooling fan 301 to turn on, allowing the adjustable speed cooling fan 301 to dissipate heat from the inside of the charging pile. The damping hydraulic rod 401 has a certain length, separating the charging pile from the vehicle at a certain distance. If the vehicle is impacted due to improper operation, the damping hydraulic rod 401 is subjected to external force, and the inner rod contracts inward. The internal piston drives the liquid to flow. The resistance generated during the liquid flow slows down the piston's movement speed, reducing the transmission of the impact force from the vehicle. The buffer spring 402 has elastic potential energy, allowing it to return to its original shape after the impact force disappears.
[0040] In summary, this Vienna rectifier high-frequency inverter charging pile, by setting up the heat dissipation component 3, can automatically activate the adjustable speed cooling fan 301, thereby improving heat dissipation efficiency. During use, the temperature sensor 303 monitors the internal temperature of the charging pile. If the temperature exceeds the preset temperature threshold for automatically activating the adjustable speed cooling fan 301, the temperature sensor 303 sends a signal to the PLC controller 302. The PLC controller 302 then controls the adjustable speed cooling fan 301 to activate, allowing it to dissipate heat from the inside of the charging pile and expel the heat to the outside. This ensures efficient heat dissipation, prevents heat from accumulating inside the charging pile's cabinet, and avoids overheating, which could affect its normal operation and help extend the equipment's lifespan.
[0041] By setting up the anti-collision component 4, the Vienna rectifier high-frequency inverter charging pile can be protected. In use, the damping hydraulic rod 401 has a certain length, which separates the charging pile from the vehicle at a certain distance. If it is hit due to improper operation, the damping hydraulic rod 401 is subjected to external force, the inner rod contracts inward, and the internal piston drives the fluid to flow. The resistance generated during the fluid flow slows down the speed of the piston movement, reducing the transmission of the impact force from the vehicle. The buffer spring 402 has elastic potential energy, which allows it to return to its original shape after the impact force disappears. At the same time, the reflector 405 can serve as a warning at night, avoiding collisions with the charging pile due to reversing or dark surroundings, which could damage the charging pile and cause losses to the charging user. This helps to protect the charging pile.
