Description

Technical Field

[0001] The utility model relates to the field of charging stations, and particularly relates to a charging station. Background Technique

[0002] With the popularization of electric vehicles and other electric devices, the demand for charging stations is increasing day by day. A charging station not only needs to provide efficient and safe charging services, but also needs to have the ability to operate stably under various environmental conditions. In order to ensure the normal operation of the internal components of the charging station, especially to avoid short-circuit problems caused by pollutants such as dust and moisture, the design of the housing of the charging station is particularly important.

[0003] The traditional charging station housing design often adopts a simple closed structure. Although it can block the entry of external pollutants to a certain extent, during long-term operation, due to changes in environmental factors such as temperature and humidity, and factors such as the heat generated by the internal components of the housing, the temperature inside the housing often rises, affecting the life and performance of the components. To solve this problem, some charging stations adopt active heat dissipation methods such as cooling fans, but these methods not only increase the complexity and cost of the equipment, but also may cause new problems due to the failure of components such as fans. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a charging station, aiming to solve the technical problems.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A charging station according to an embodiment of the utility model includes a housing. An installation cavity is provided inside the housing. An air inlet channel one is provided on the side wall of the housing. A one-way valve one is fixed to the inner wall of the air inlet channel one. Above the one-way valve one, a one-way valve two is slidably connected to the inner wall of the air inlet channel one. A piston rod for driving it to reciprocate vertically is fixed to the top of the one-way valve two. Above the one-way valve two, a connection channel horizontally arranged and communicating with the installation cavity is provided. When the device is not in use, the inside of the installation cavity is not communicated with the outside of the housing, reducing the possibility of short circuit of the components inside the installation cavity due to pollution.

[0007] As a preferred technical solution of the utility model, the one-way valve one includes a mounting plate one fixed to the inner wall of the installation cavity. A vertically arranged air inlet through hole one penetrates through the bottom of the mounting plate one. A cover plate one is rotatably connected to the top of the mounting plate one. A connection block one is fixed to the top of the cover plate one. An arc-shaped telescopic rod is fixedly installed between the inner wall of the installation cavity and the connection block one. A compression spring one is installed between the fixed end of the arc-shaped telescopic rod and the connection block one. When the piston rod drives the one-way valve two to move upward, the one-way valve two closes, the cover plate one flips, and the air inlet through hole one intakes air.

[0008] As a preferred technical solution of the present utility model, the second one-way valve includes a second mounting plate slidably connected to the inner wall of the mounting cavity. A fixed bridge is fixed to the top of the second mounting plate. The fixed bridge is a four-claw structure. The top of the fixed bridge is fixedly connected to the bottom of the piston rod. A second compression spring is fixed to the inner wall of the top of the fixed bridge. A plug cap is fixed to the bottom of the second compression spring. An air inlet passage two is provided at the top of the second mounting plate and is located directly below the plug cap. The plug cap is trapezoidal and seals the top of the air inlet passage two. When the piston rod drives the second one-way valve to move downward, the first one-way valve closes, the plug cap moves upward, the second compression spring contracts, and the air inlet passage two admits air.

[0009] As a preferred technical solution of the present utility model, a cavity is provided above the air inlet passage one and is located inside the housing. A reciprocating wire cylinder is fixed inside the cavity. A connecting block is slidably connected to the guide groove on the outer wall of the reciprocating wire cylinder. The connecting block is fixed to the side wall of the top of the piston rod.

[0010] As a preferred technical solution of the present utility model, the bottom of the air inlet passage one is inclined downward. A filter screen is provided at the bottom opening of the mounting cavity. The inner wall of the mounting cavity away from the air inlet passage one is provided with an air outlet passage communicating with the outside of the housing. A third one-way valve is fixed inside the air outlet passage. The gas that enters the mounting cavity through the air inlet passage one for heat exchange is moved to the outside of the housing after passing through the third one-way valve in the air outlet passage.

[0011] As a preferred technical solution of the present utility model, a storage groove is provided on the front end face of the housing. An operation panel is fixed to the inner wall of the storage groove. A charging gun is inserted into the storage groove. A storage hook is fixed to the inner wall of the storage groove. It is convenient for users to operate and convenient to charge electrical components such as the vehicle to be charged.

[0012] As a preferred technical solution of the present utility model, a horizontally arranged flow equalizing plate is fixed inside the mounting cavity. One end of the flow equalizing plate is inserted into the connecting channel. It shunts the airflow entering the mounting cavity.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Improve safety: When the device is not in use, through the unique one-way valve design, it is ensured that the inside of the mounting cavity is not connected to the outside of the housing, effectively preventing pollutants such as dust and water vapor from entering the mounting cavity, greatly reducing the risk of short circuit of internal components due to pollution, and improving the overall safety and stability of the charging station.

[0015] Intelligent ventilation adjustment: Through the coordinated action of the second one-way valve driven by the piston rod and the first one-way valve, intelligent control of the air inlet passage is realized. When ventilation and heat dissipation are required, the piston rod drives it to move downward or upward, respectively opening or closing the corresponding air inlet passage, ensuring necessary air circulation while avoiding unnecessary energy loss and intrusion of external pollutants.

[0016] Efficient heat dissipation design: The bottom of the first intake channel is inclined downward. Cooperating with the filter screen at the bottom of the installation cavity, it can effectively prevent debris from entering and guide the air flow to enter smoothly. The one-way valve three in the air outlet channel ensures that the gas after heat exchange can be discharged smoothly, improving the heat dissipation efficiency. In addition, the design of the flow equalizing plate further optimizes the air flow distribution, making the temperature in the installation cavity more uniform and extending the service life of the internal components.

[0017] Convenient operation and maintenance: The operation panel and charging gun storage design on the front end face of the housing not only facilitate the operation of the user, but also provide a convenient charging gun storage solution, reducing the time for searching and organizing the charging gun and improving the charging efficiency. At the same time, this design also facilitates the daily maintenance and inspection of the charging station.

[0018] Compact structure and comprehensive functions: Through the ingenious structural design, the present invention integrates multiple functions into a compact housing, which not only saves space, but also realizes multiple functions such as efficient heat dissipation, safety protection and convenient operation, and has high practical value and market promotion potential.

[0033] Embodiment 1

[0034] As Figures 1-4As shown in the figure, the utility model provides a charging station, which includes a housing 10. A storage slot is provided on the front end face of the housing 10. An operation panel 11 is fixed on the inner wall of the storage slot. A charging gun 12 is inserted into the storage slot. A storage hook 13 is fixed on the inner wall of the storage slot. An installation cavity 20 is provided inside the housing 10. An air inlet channel one 30 is provided on the side wall of the housing 10. A one-way valve one 40 is fixed on the inner wall of the air inlet channel one 30. Above the one-way valve one 40, there is a one-way valve two 50 slidably connected to the inner wall of the air inlet channel one 30. The top of the one-way valve two 50 is fixed with a piston rod 60 that drives it to reciprocate vertically. Above the one-way valve two 50, there is a horizontally arranged connection channel 32 that communicates with the installation cavity 20. The one-way valve one 40 includes a mounting plate one 41 fixed on the inner wall of the installation cavity 20. A vertically arranged air inlet through hole one 42 penetrates through the bottom of the mounting plate one 41. The top of the mounting plate one 41 is rotatably connected with a cover plate one 43. A connecting block one 44 is fixed on the top of the cover plate one 43. An arc-shaped telescopic rod 45 is fixedly installed between the inner wall of the installation cavity 20 and the connecting block one 44. A compression spring one 46 is installed between the fixed end of the arc-shaped telescopic rod 45 and the connecting block one 44. When the piston rod 60 drives the one-way valve two 50 to move upward, the one-way valve two 50 closes, the cover plate one 43 flips, and the air inlet through hole one 42 intakes air. The one-way valve two 50 includes a mounting plate two 51 slidably connected to the inner wall of the installation cavity 20. A fixed bridge 52 is fixed on the top of the mounting plate two 51. The fixed bridge 52 is a four-claw structure. The top of the fixed bridge 52 is fixedly connected to the bottom of the piston rod 60. A compression spring two 53 is fixed on the inner wall of the top of the fixed bridge 52. The bottom of the compression spring two 53 is fixed with a plug cap 54. An air inlet channel two is provided on the top of the mounting plate two 51 and is located directly below the plug cap 54. The plug cap 54 is trapezoidal and blocks the top of the air inlet channel two. When the piston rod 60 drives the one-way valve two 50 to move downward, the one-way valve one 40 closes, the plug cap 54 moves upward, the compression spring two 53 contracts, and the air inlet channel two intakes air. When the device is not in use, the inside of the installation cavity 20 is not communicated with the outside of the housing 10, reducing the possibility of short circuit of the components inside the installation cavity 20 due to pollution, facilitating the operation of the user, and facilitating the charging of electrical components such as the vehicle to be charged.

[0035] Specifically, above the air inlet channel one 30, there is a cavity located inside the housing 10. A reciprocating wire cylinder 61 is fixed in the cavity. A connecting block is slidably connected in the guiding groove on the outer wall of the reciprocating wire cylinder 61.

[0036] Specifically, the bottom of the air inlet channel one 30 is inclined downward. A filter screen 31 is provided at the bottom opening of the installation cavity 20. On the inner wall of the installation cavity 20 away from the air inlet channel one 30, there is an air outlet channel communicating with the outside of the housing 10. A one-way valve three is fixed in the air outlet channel. The gas that enters the installation cavity 20 through the air inlet channel one 30 for heat exchange moves to the outside of the housing 10 after passing through the one-way valve three in the air outlet channel.

[0037] Specifically, a horizontally arranged flow equalizing plate 21 is fixed inside the installation cavity 20, and one end of the flow equalizing plate 21 is inserted into the connection channel 32 to divide the airflow entering the installation cavity 20.

[0038] In summary, when the charging station is not in use, the cover plate 43 of the one-way valve 40 and the plug cap 54 of the one-way valve 50 are both in a closed state, ensuring that the inside of the installation cavity 20 is not communicated with the outside of the housing 10.

[0039] When heat dissipation is required, the reciprocating wire cylinder 61 drives the piston rod 60 to move downward, driving the one-way valve 50 to move downward and the plug cap 54 to move upward, opening the second intake channel. External air enters the installation cavity 20 through the first intake channel 30 and the second intake channel for heat exchange.

[0040] The gas after heat exchange is discharged outside the housing 10 through the one-way valve 3 in the air outlet channel.
