[0002] Electric vehicles are vehicles that use onboard power sources to drive their wheels with electric motors and meet all road traffic and safety regulations. Compared to gasoline-powered vehicles, electric vehicles have a smaller environmental impact and can replace the use of non-renewable gasoline. As electric vehicles become increasingly popular, the demand for charging stations is also increasing. Among them, wall-mounted charging stations are widely used due to their small size and minimal footprint.
[0003] Existing wall-mounted DC charging piles for new energy vehicles integrate a large number of components, causing the power module inside the charging pile to heat up during use. This reduces the heat dissipation efficiency of the electronic components inside the equipment, making them prone to aging and short circuits. In addition, the leakage protection switch inside the equipment requires maintenance by personnel over a long period of time. This involves disassembly and assembly by rotating bolts and nuts, which reduces the efficiency of disassembly and assembly and increases the workload of personnel. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a wall-mounted DC charging pile for new energy vehicles, which has the advantages of high heat dissipation efficiency and easy disassembly and assembly of leakage protection switches, thus solving the problems mentioned in the background technology.

[0006] As a preferred technical solution of this utility model: the outer wall of the leakage protection switch is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the fixing rod.
[0007] As a preferred technical solution of this utility model: the number of the locking blocks is several, and the outer walls of the several locking blocks are engaged with the outer walls of the fixing rod.
[0008] As a preferred technical solution of this utility model: heat dissipation windows are fixedly installed on the outer wall of the pile body, and two heat dissipation windows are distributed on the two outer walls of the pile body.
[0009] As a preferred technical solution of this utility model: the power module is electrically connected to the fan, the leakage protection switch and the display screen respectively, and the fan is located above the top of the through hole.
[0010] As a preferred technical solution of this utility model: an input line port is fixedly installed at the bottom of the pile body, and an output line port is fixedly provided at the bottom of the pile body.
[0011] As a preferred technical solution of this utility model: a partition is fixedly installed on the inner wall of the pile body, and the inner wall of the partition has a plurality of round holes.
[0012] As a preferred technical solution of this utility model: an electrical module is fixedly installed on the outer wall of the partition, and the partition separates the power module from the electrical module.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This wall-mounted DC charging pile for new energy vehicles uses a fan located above the through-hole. The power module is connected to the power supply and transmits an electrical signal to the fan, causing the fan to rotate and generate airflow. This airflow dissipates the heat from the inner wall of the pile through the through-hole, thereby improving the heat dissipation efficiency of the equipment. Several circular holes are opened on the inner wall of the partition. When the fan dissipates heat, it passes through these holes to achieve uniform heat dissipation, improving the practicality of the equipment. In this way, the heat generated by the power module during operation can be prevented from being directly conducted to the outer wall of the electrical module, avoiding high-temperature damage.
[0015] 2. This wall-mounted DC charging pile for new energy vehicles, by rotating the box door, uses external force to drive the leakage current protection switch to slide on the outer wall of the fixed rod, so that the leakage current protection switch is positioned on the outer wall of the fixed rod. The outer walls of several locking blocks overlap with the outer walls of the fixed rod. When the leakage current protection switch slides to a certain position on the outer wall of the fixed rod, external force is used to press the leakage current protection switch, so that the leakage current protection switch drives the locking blocks to engage on the outer wall of the fixed rod, achieving quick installation.

[0023] Please see Figures 1-5 A wall-mounted DC charging pile for new energy vehicles includes a pile body 1, an antenna 2 fixedly installed on the outer wall of the pile body 1, a door 10 installed on the outer wall of the pile body 1, a display screen 6 fixedly installed on the outer wall of the door 10, a door lock 4 fixedly installed on the outer wall of the door 10, a card swiping area 5 fixedly installed on the outer wall of the door 10, a bracket 12 fixedly installed on the inner wall of the pile body 1, a fan 11 fixedly installed on the inner wall of the bracket 12, a through hole 13 opened at the bottom of the pile body 1, a fixing rod 15 fixedly installed on the inner wall of the pile body 1, a leakage current protection switch 14 installed on the inner wall of the fixing rod 15, a locking block 16 fixedly installed on the outer wall of the leakage current protection switch 14, a charging gun socket 9 fixedly installed on one side of the outer wall of the pile body 1, a power module 18 fixedly installed on the inner wall of the pile body 1, and an emergency stop button 3 fixedly installed on the outer wall of the pile body 1.
[0024] In the above structure, the installation of a leakage protection switch 14 in the equipment prevents electric shock when the electrical equipment on the inner wall of the pile body 1 experiences a leakage fault. It also has overload and short circuit protection functions and can be used to protect the line or power supply module from overload and short circuit.
[0025] In a preferred embodiment, the outer wall of the leakage current protection switch 14 is provided with a groove 17, and the inner wall of the groove 17 is slidably connected to the outer wall of the fixing rod 15.
[0026] In the above structure, the inner wall of the slide groove 17 and the outer wall of the fixed rod 15 form a sliding connection. The leakage current protection switch 14 is driven by external force to slide the slide groove 17 on the outer wall of the fixed rod 15, so that the leakage current protection switch 14 and the outer wall of the fixed rod 15 are installed.
[0027] In a preferred embodiment, there are several locking blocks 16, and the outer walls of several locking blocks 16 are engaged with the outer wall of the fixing rod 15.
[0028] In the above structure, the outer walls of several locking blocks 16 overlap with the outer wall of the fixing rod 15. When the leakage protection switch 14 slides to a certain position on the outer wall of the fixing rod 15, the leakage protection switch 14 is pressed by external force, so that the leakage protection switch 14 drives the locking blocks 16 to engage with the outer wall of the fixing rod 15, thereby achieving quick installation.
[0029] In a preferred embodiment, a heat dissipation window 19 is fixedly installed on the outer wall of the pile body 1, and two heat dissipation windows 19 are distributed on the two outer walls of the pile body 1.
[0030] In the above structure, two heat dissipation windows 19 are distributed on both sides of the outer wall of the pile body 1. The two heat dissipation windows 19 are used to achieve ventilation and heat dissipation effect on the inner wall equipment of the pile body 1, thereby improving the practicality of the equipment.
[0031] In a preferred embodiment, the power module 18 is electrically connected to the fan 11, the leakage protection switch 14, and the display screen 6, respectively, with the fan 11 located above the top of the through hole 13.
[0032] In the above structure, the fan 11 is located above the through hole 13. The power supply module 18 is used to connect the power supply and transmit the electrical signal to the fan 11, so that the fan 11 rotates to generate airflow, which discharges the heat of the inner wall of the pile body 1 to the outside through the through hole 13, thereby improving the heat dissipation efficiency of the equipment.
[0033] In a preferred embodiment: an input port 7 is fixedly installed at the bottom of the pile body 1, an output port 8 is fixedly installed at the bottom of the pile body 1, a partition 20 is fixedly installed on the outer wall of the pile body 1, and an electrical connection is formed between the power module 18 and the partition 20.
[0034] In the above structure, the power module 18 controls the microcontroller or digital signal processor. By collecting and processing relevant information of the battery, electric vehicle and charging pile, such as voltage, current and temperature, the operating status and output power of the power module 18 are controlled. According to the current status of the electric vehicle battery and charging needs, the output voltage and current are adjusted, and the operating conditions and safety performance are monitored at the same time.
[0035] In a preferred embodiment: a partition plate 20 is fixedly installed on the inner wall of the pile body 1, and the inner wall of the partition plate 20 has a plurality of round holes.
[0036] In the above structure, several round holes are provided on the inner wall of the partition 20. When the fan 11 exhausts heat through the round holes, uniform heat dissipation is achieved, which improves the practicality of the equipment.
[0037] In a preferred embodiment, an electrical module 21 is fixedly installed on the outer wall of the partition 20, and the partition 20 separates the power module 18 from the electrical module 21.
[0038] In the above structure, the power module 18 and the electrical module 21 are separated by the partition 20, so that the heat generated by the power module 18 during operation can be prevented from being directly conducted to the outer wall of the electrical module 21, thus avoiding high temperature damage.
[0039] Working principle: By rotating the door 10, external force is used to move the leakage current protection switch 14 along the slide rail 17 to slide against the outer wall of the fixed rod 15, thus positioning the leakage current protection switch 14 against the outer wall of the fixed rod 15. Several locking blocks 16 engage with the outer wall of the fixed rod 15. When the leakage current protection switch 14 slides to a certain position on the outer wall of the fixed rod 15, external force is applied to press the leakage current protection switch 14, causing it to engage with the locking blocks 16 against the outer wall of the fixed rod 15, achieving quick installation. The equipment is then connected to the power supply. The fan 11 is located above the through hole 13. The power module 18 is connected to the power supply and transmits an electrical signal to the fan 11, causing the fan 11 to rotate and generate airflow. This airflow dissipates the heat from the inner wall of the pile body 1 through the through hole 13, thereby improving the heat dissipation efficiency of the equipment. Several round holes are provided on the inner wall of the partition 20. When the fan 11 dissipates heat, it passes through the round holes to achieve uniform heat dissipation and improve the practicality of the equipment. Thus, the heat generated by the power module 18 during operation can be prevented from being directly conducted to the outer wall of the electrical module 21, avoiding high-temperature damage.
