Description

Technical Field

[0001] This utility model relates to the field of charging pile technology, specifically a modularly assembled electric vehicle charging pile. Background Technology

[0002] Traditional electric vehicle charging stations are mostly integrated structures, with various functional components (such as charging gun storage, card reader, and power supply elements) installed separately and connected in a complex manner. During installation, each component needs to be fixed and debugged individually, and later, if a component is damaged, the entire system needs to be disassembled and repaired, resulting in low maintenance efficiency and high costs. The internal wiring of the power supply system is messy, lacking an orderly layout and supporting structure. Transformers and protection components are prone to circuit failure due to vibration or poor contact. Furthermore, the integration of leakage protection and circuit on / off control functions is low, posing safety hazards. The layout of the operation interface and functional areas is unreasonable. The card reader area and charging gun storage position are often at an inconvenient height, affecting ease of use. There is a lack of real-time data monitoring devices, making it difficult to intuitively grasp the charging status. Utility Model Content

[0003] The purpose of this utility model is to solve the problems of traditional electric vehicle charging piles, which have a modular assembly structure, resulting in low installation and maintenance efficiency and high cost due to the complex connection of functional components, messy power supply system lines and low integration of protection functions, posing safety hazards.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] A modularly assembled electric vehicle charging station includes a carrier box. The front of the carrier box has an opening and closing assembly. Charging gun storage units are located on the lower left and right sides of the carrier box. Card-swiping unit assemblies are located on the upper left and right sides of the carrier box, above the charging gun storage units. A rain cover is provided on the top of the carrier box. A base is provided on the bottom of the carrier box. Ventilation holes are provided on the rear side of the carrier box. A power supply assembly is located inside the carrier box. An internal data display is located at the outer outlet on the upper inner side of the carrier box. The power supply assembly includes a support pad, a conduit, a transformer, an air module, a leakage current device (RCD), and a power source. The transformer, air module, and RCD are all supported by the support pad, and all are connected to the conduit.

[0006] Furthermore, the opening and closing assembly includes a front cover door and an advertising space. The front cover door and the advertising space are located on the front side of the carrier box. The advertising space is located on the front side of the front cover door. In the opening and closing assembly on the front side of the carrier box, the front cover door can be opened for maintenance of the internal components.

[0007] Furthermore, the charging gun storage unit includes a storage cavity, a charging gun assembly, and a cavity buckle. The storage cavity is located on both sides of the carrier box, and the inner end of the cavity buckle is fixedly connected to the outer wall of the carrier box. After the user connects the charging gun body to the electric vehicle charging interface, the charging pile automatically starts the charging program: the power supply component transmits the processed current to the charging gun assembly through the line pipe to power the electric vehicle.

[0008] Furthermore, the inner end of the charging gun assembly is inserted into the inner side of the storage cavity, and the bottom end of the charging gun assembly is snapped into the inner side of the cavity buckle. When charging is complete, the user removes the charging gun body, inserts it back into the storage cavity, and fastens the cavity buckle to complete the reset.

[0009] Furthermore, the charging gun assembly includes a charging gun body and a temperature monitoring display. The temperature monitoring display is located on the top side of the charging gun body. The temperature monitoring display continuously monitors the temperature of the charging gun body. If the temperature exceeds a safe threshold, it will activate the air module through an internal circuit to suspend charging and prevent overheating damage.

[0010] Furthermore, the card swiping unit assembly includes a card swiping display and a card swiping sensor. The card swiping sensor is located at the bottom of the card swiping display, and the back of the card swiping display is located at both ends of the outer side of the carrier box. When charging is complete, the card swiping display displays information such as charging amount and duration.

[0011] Furthermore, the support pad is fixedly connected to the inner wall of the carrier box. The wiring conduit, the transformer, the air module, the leakage current protector, and the power supply are all located inside the carrier box. The power supply is located at the bottom inner side of the carrier box. The leakage current protector and the air module in the power supply assembly are restored to standby status, waiting for the next charging operation.

[0012] Compared with the prior art, this utility model provides a modularly assembled electric vehicle charging station, which has the following advantages:

[0013] This modularly assembled electric vehicle charging station integrates modular structures such as opening and closing components, charging gun storage units, and card swiping units. Each component has a clear division of labor and is easy to connect, facilitating installation and subsequent maintenance and replacement. In the power supply components, the transformer, air module, and leakage protector supported by the support pad are connected in an orderly manner through conduit, forming a safe and stable power supply system in conjunction with the power supply. The leakage protector can prevent leakage risks in real time, and the air module ensures that the circuit connection and disconnection are controllable, improving charging safety. The internal data display can monitor charging data in real time. The vertical layout of the card swiping unit and charging gun storage unit conforms to ergonomic operating habits, improving the overall practicality, safety, and operation and maintenance efficiency of the charging station, making it suitable for various outdoor charging scenarios.

The inner end of the charging gun assembly 32 is inserted into the inner side of the storage cavity 31, and the bottom end of the charging gun assembly 32 is snapped into the inner side of the cavity buckle 33. The charging gun assembly 32 includes a charging gun body 321 and a temperature monitoring device. Display 322, temperature monitoring display 322 is set on the top side of charging gun body 321. The user takes out the charging gun assembly 32 from the charging gun storage unit 3 on both sides of the carrier box 1 - opens the cavity buckle 33, and pulls the charging gun body 321 out of the storage cavity 31. At this time, the temperature monitoring display 322 on the top side of the charging gun body 321 is activated and displays the gun body temperature in real time. When charging is complete, the user pulls out the charging gun body 321, inserts it back into the storage cavity 31 and fastens the cavity buckle 33 to complete the reset.

[0025] like Figure 4 As shown, a card reader assembly 4 is provided on the upper left and right sides of the outer side of the carrier box 1. The card reader assembly 4 is located above the charging gun storage unit 3. The card reader assembly 4 includes a card reader display 41 and a card reader sensor 42.

The operation of the card reader assembly 4 on the upper outer side of the carrier box 1 is as follows: when the charging card is placed close to the card reader sensor 42, the card reader display 41 displays information such as the card balance and charging mode, thus completing the identity verification and charging parameter confirmation.

[0026] like Figure 1 As shown, a rain cover 5 is provided at the top of the carrier box 1, a base 6 is provided at the bottom of the carrier box 1, and a heat dissipation hole 7 is provided at the rear side of the carrier box 1. The base 6 at the bottom of the carrier box 1 ensures that the equipment is placed stably. The rain cover 5 at the top and the heat dissipation hole 7 at the rear side play the roles of rain protection and internal heat dissipation, respectively, ensuring that the internal components operate normally in the outdoor environment.

[0027] Example 2:

[0028] like Figure 5 and Figure 6As shown, the power supply component 8 is installed inside the carrier box 1. The power supply component 8 includes a support pad 81, a conduit 82, a transformer 83, an air module 84, a leakage current protector 85, and a power supply 86. The transformer 83, the air module 84, and the leakage current protector 85 are all supported by the support pad 81. The transformer 83, the air module 84, the leakage current protector 85, and the power supply 86 are all connected to the conduit 82. The support pad 81 is fixedly connected to the inner wall of the carrier box 1. The conduit 82, the transformer 83, the air module 84, the leakage current protector 85, and the power supply 86 are all located inside the carrier box 1. The power supply 86 is located at the bottom inner side of the carrier box 1. The charging pile is connected to the power supply component 8 inside the carrier box 1: the power supply 86 is connected to the external power grid through the conduit 82. The current passes sequentially through the leakage current protector 85 (which monitors leakage in real time and immediately cuts off the power when leakage occurs), the air module 84 (which controls the circuit on and off), and the transformer 83 (which converts the mains power into a voltage suitable for charging), providing safe and stable power for the entire device.

[0029] like Figure 1 As shown, an inner data display 9 is installed at the outer outlet of the upper inner side of the carrier box 1. During the charging process, the inner data display 9 (located at the outer outlet of the upper inner side of the carrier box 1) displays the total charging amount, current voltage, current and other core data in real time, so that maintenance personnel can monitor the operating status of the equipment.

[0030] Working principle: such as Figures 1-6 As shown, the equipment is started and prepared: The charging pile is powered by the power supply component 8 inside the carrier box 1: the power supply 86 is connected to the external power grid through the line pipe 82, and the current passes through the leakage protection device 85 (which monitors leakage in real time and cuts off the power immediately when leakage occurs), the air module 84 (which controls the circuit on and off), and the transformer 83 (which converts the mains power into a voltage suitable for charging) in sequence, providing safe and stable power for the entire equipment; the base 6 at the bottom of the carrier box 1 ensures that the equipment is placed stably, and the rain cover 5 at the top and the heat dissipation hole 7 at the rear play the roles of rain protection and internal heat dissipation, respectively, to ensure that the internal components operate normally in the outdoor environment;

[0031] User interaction and charging initiation: When a user needs to charge, they first operate the card swiping unit component 4 on the upper outer side of the carrier box 1: place the charging card close to the card swiping sensor 42, and the card display 41 will display information such as the card balance and charging mode, completing identity verification and charging parameter confirmation; then, the user takes out the charging gun component 32 from the charging gun storage unit 3 on both sides of the carrier box 1 - open the cavity buckle 33, and pull the charging gun body 321 out of the storage cavity 31. At this time, the temperature monitoring display 322 on the top side of the charging gun body 321 is activated, displaying the gun body temperature in real time (to avoid charging failure due to high temperature);

[0032] Charging Process and Monitoring: After the user connects the charging gun 321 to the electric vehicle charging interface, the charging pile automatically starts the charging program: the power supply component 8 transmits the processed current to the charging gun component 32 through the line pipe 82 to power the electric vehicle; during the charging process, the inner data display 9 (located at the upper outlet inside the carrier box 1) displays the total charging amount, current voltage, current and other core data in real time, allowing maintenance personnel to monitor the equipment's operating status; the temperature monitoring display 322 continuously monitors the temperature of the charging gun 321. If the temperature exceeds the safety threshold, it will trigger the air module 84 through the internal circuit to stop charging to prevent overheating damage;

[0033] Charging Completion and Device Reset: When charging is complete (or the user actively terminates charging via the card reader component 4), the card reader display 41 shows information such as charging amount and duration. The user removes the charging gun body 321, inserts it back into the storage cavity 31, and fastens the cavity buckle 33 to complete the reset. At this time, the leakage protector 85 and air module 84 in the power supply component 8 return to standby mode, waiting for the next charging operation. In the opening and closing component 2 on the front side of the carrier box 1, the front cover door 21 can be opened for internal component maintenance, and the advertising space 22 can display charging instructions or business information to improve the practicality of the device.
