Figure 1 As shown, the charging pile body is equipped with a controller, and the charging pile body is connected to multiple charging sockets (i.e. one to many), and each charging socket can be used to charge multiple electric bicycles at the same time. This charging is also conventional charging, and it usually takes about 6-8 hours to fully charge. Electric vehicle charging piles have fast charging, but there is no mature fast charging product for electric bicycles. Utility Model Content

An air inlet and an air outlet are arranged at the bottom of the shell. The heat dissipation fan is located in the shell.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0021] Embodiments of the present utility model:
[0022] like Figure 1-Figure 3 As shown, the heat dissipation structure of the electric bicycle charging pile includes a housing, a heat dissipation fan 5, and an air duct. The bottom of the housing is provided with an air inlet 21 and an air outlet 22. The heat dissipation fan 5 is located in the housing, and the heat dissipation fan 5 is located at one end of the air duct, and the other end of the air duct is connected to the air outlet 22. The heat dissipation fan 5 is used to dissipate the heat generated during the use of the charging pile.
[0023] The shell is a circular shell, including a front shell 1 and a rear shell 2 that are buckled together. The cable through hole 23, the air inlet 21, and the air outlet 22 are all arranged on the rear shell 2. A circular sealing ring is arranged at the joint between the front shell 1 and the rear shell 2. The front shell 1 and the rear shell 2 are connected by a number of screws. When the front shell 1 and the rear shell 2 are squeezed, the sealing ring is deformed to achieve sealing, so that the shell has waterproof performance. The rear shell 2 is provided with a fixing hole, and the rear shell 2 can be fixed to the wall by using expansion screws.
[0024] A cable hole 23 is provided at the bottom of the rear shell 2 for the cable of the charging gun to pass through, and the air inlet 21 and the air outlet 22 are respectively located on the left and right sides of the cable hole 23. The charging gun (not shown) is used in conjunction with the fast charging socket on the electric bicycle, and the method of use is similar to that of charging an electric car, but different from the traditional method of charging an electric bicycle. With the electric bicycle charging pile of the utility model, a traditional power adapter is no longer required. The electric bicycle charging pile is designed for fast charging of electric bicycles. The utility model mainly relates to the heat dissipation structure part, and the remaining design points are reflected in other patent applications.
[0025] The air inlet 21 and the air outlet 22 are both grid structures including a number of heat dissipation holes, and the highest points of the grid structures are all lower than the center of the shell. While satisfying ventilation and heat dissipation, rainwater is prevented from entering the shell through the heat dissipation holes to avoid damaging the circuit structure therein. The air inlet 21 and the air outlet 22 are symmetrical about the center of the shell, and for the sake of ease of description, they are referred to as grid structures below. The air outlet 22 has an air outlet direction that is obliquely downward and can be staggered from the air inlet direction to improve the heat dissipation effect. In this embodiment, the grid structure is composed of criss-crossed ribs, and the heat dissipation holes are strip holes; in other embodiments, multiple circular heat dissipation holes can also be set.
[0026] Furthermore, the outer side of the grid structure protrudes from the outer peripheral surface of the rear shell 2, and the top of the grid structure forms a water-falling slope 211 at the contact point with the outer peripheral surface of the rear shell 2. When it rains, rainwater flows along the outer peripheral surface of the shell to the water-falling slope 211 and falls to the ground, and is not easy to enter the interior of the shell.
[0027] Furthermore, an arc groove 3 is formed between the side of the grid structure close to the front shell 1 and the front shell 1, that is, the edge of the grid structure does not reach the front end surface of the rear shell 2, and a narrow groove will be formed after the front shell 1 is buckled. Through the design of the arc groove 3, a small amount of rainwater passes through it and flows along the outer peripheral surface of the rear shell 2 to the bottom of the shell, and then falls to the ground, and will not enter the inside of the shell. Therefore, the charging pile shell has good waterproof performance.
[0028] The air duct includes a common channel 41 and several independent channels 42. Each independent channel 42 is connected to one end of the common channel 41, and the other end of the common channel 41 is connected to the air outlet 22. The inner cavity of the common channel 41 is larger than the inner cavity of the independent channel 42. At least one cooling fan 5 is provided in each independent channel 42. The independent channel 42 is configured as a rectangular channel and can be made of a profile. The cooling fan 5 is connected to the independent channel 42 by screws and can be made into a module. The cooling fan 5 can be controlled independently to adjust the heat dissipation intensity according to the use of the charging pile (such as the temperature feedback from the temperature sensor in the shell, or according to parameters such as the continuous charging time).
[0029] The front shell 1 is provided with a mounting opening 11 for mounting a display window, and the display window is used to display data such as charging time and user balance.
