Description

TECHNICAL FIELD

[0001] The application relates to the technical field of charging piles, and in particular to a charging pile heat dissipation structure and an automobile charging pile. BACKGROUND

[0002] The charging pile is similar in function to a refueling machine in a gas station, can be fixed to the ground or a wall, is installed in a public building and a residential parking lot or a charging station, and can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected with an alternating current power grid, and the output end is provided with a charging plug for charging electric vehicles.

[0003] Referring to Chinese patent CN 116788079 B, a charging pile heat dissipation structure and an automobile charging pile are disclosed. The application completes heat dissipation of the internal structure of the charging pile through the air conveying assembly. The air conveying assembly is provided in two, air can be input into the charging pile from both sides to accelerate the heat dissipation speed and reduce the heat dissipation time. When the charging pile does not need to be cooled, the cover plate covers the heat dissipation port to avoid damage to the internal structure of the charging pile. In addition, the support frame pulls the cover plate up through the traction piece to avoid the obstruction of the cover plate preventing air from being conveyed into the charging pile.

[0004] However, the above and similar technical solutions still have some problems in actual use.

[0005] 1. In the operation process of the heat dissipation system, although directly introducing ambient air as the cooling medium can realize an effective heat exchange process, this method also brings the risk of wet air (i.e., air containing a high water content) penetrating into the heat dissipation system. In the long term, the accumulation of wet air may cause the internal components of the controller to be corroded and electrically short-circuited, thereby significantly threatening the service life of the controller. In addition, the traditional fixed-direction fan blowing mode has limitations in the comprehensiveness and efficiency of heat exchange, and it is difficult to achieve the optimal state of the performance of the heat dissipation system, thereby limiting the improvement of the overall heat dissipation effect.

[0006] 2. The charging column lacks necessary protection mechanisms in the design aspect, so that it is easily eroded by rain for a long time when exposed in an outdoor environment, thereby causing physical damage or electrical system failure. In addition, due to the lack of dustproof measures, dust is easy to deposit and accumulate on the surface of the charging column, which not only affects the normal operation state and heat dissipation performance of the equipment, but also may pose a potential threat to the long-term stable operation of the equipment. More seriously, in the case of fire and other emergencies, since the charging column lacks effective fire blocking structure design, the flame and heat may quickly spread to the adjacent area, thereby aggravating the severity of the disaster and posing a major risk to public safety.

[0007] 3. As an important component of external charging devices, charging cables have a relatively fragile physical structure and are easily damaged by various external factors. Especially during long-term and frequent use, charging cables are frequently in contact with the ground and dragged. This physical friction greatly accelerates the aging and damage process. This not only affects the charging efficiency and safety of the charging cable, but also increases the risk of short circuits due to line damage, posing a potential threat to the safety and stability of the charging process. Therefore, strengthening the physical protection and durability design of charging cables is particularly important. Summary of the Invention

[0045] Example 2:

[0046] Based on Example 1, referring to Figure 4 and Figure 6A car charging station includes a protective mechanism 5 connected to the main body 1 of the charging station. The protective mechanism 5 includes an electric push rod 54, which is installed inside the main body 1. A second pulley 55 is installed at the telescopic end of the electric push rod 54, and a pull rope 56 is wound around the second pulley 55. A top plate 51 is installed at the top of the main body 1. A counterweight ring 53 is slidably sleeved on the outer wall of the main body 1. A fireproof cloth 52 is installed between the counterweight ring 53 and the top plate 51. Both ends of the pull rope 56 are fixed to the counterweight ring 53, thereby protecting against rain and dust and isolating oxygen in case of fire, thus playing a fire-extinguishing role.

[0047] In this invention, the outer wall of the fireproof cloth 52 is coated with waterproof paint, and the fireproof cloth 52 is corrugated, which facilitates the folding up of the fireproof cloth 52.

[0048] In this invention, two pairs of third pulleys 57 are installed at the top of the charging column body 1, and the two ends of the pull rope 56 are respectively wrapped around the two pairs of third pulleys 57, thereby facilitating the guidance of the pull rope 56 and reducing wear.

[0049] In this invention, a pair of pads 58 are installed at the top of the charging column body 1, and the top plate 51 is fixedly connected to the pads 58. The top plate 51 is installed at the top of the charging column body 1 through the pair of pads 58, thereby facilitating the fixation of the top plate 51.

[0050] Example 3:

[0051] Based on Example 2, referring to Figure 2 and Figure 3 A car charging station is provided, wherein the bottom end of the charging station body 1 is connected to an extension mechanism 2, the extension mechanism 2 includes an electric scissor-type telescopic frame 22, the bottom end of the charging station body 1 is equipped with the electric scissor-type telescopic frame 22, the end of the electric scissor-type telescopic frame 22 is equipped with a closing plate 21, mounting plates 25 are rotatably connected to the two rotating shafts on both sides of the electric scissor-type telescopic frame 22, the mounting plates 25 are equipped with first pulleys 23, and the mounting plates 25 are threaded with knobs 24 above the first pulleys 23. The charging station body 1 is equipped with a charging cable 26, the charging cable 26 is wound in an "S" shape around multiple first pulleys 23, the closing plate 21 is equipped with a bracket 27, and the plug end of the charging cable 26 is inserted into the bracket 27, thereby avoiding friction and dragging of the charging cable 26 with the ground and extending its lifespan.

[0052] Working principle: Controller 4 is used for power control. When supplying power to the car, controller 4 generates heat, activating the first fan 31 and the second fan 32. The second fan 32 creates negative pressure inside the air duct 33, filtering the air through the adsorption bag 35 at one end of the air duct 33 to remove moisture. External air is drawn in and blown towards the back of controller 4, thus dissipating heat. The hot air inside the charging column body 1 is drawn outward by the first fan 31. The hot air passes through the adsorption bag 35 at one end of the first fan 31, thus expelling the moisture inside the adsorption bag 35, drying the adsorption bag 35, and facilitating circulation. Motor 7 is then activated, driving the second gear 8 to rotate. This drives the internal gear 36 to rotate, which in turn drives the mesh ring 37 to rotate, thereby causing the adsorption bag 35 inside the slot 38 on the mesh ring 37 to rotate. This continuously causes the adsorption bag 35 to switch back and forth between the two air outlets 34, thus achieving the purpose of filtering moisture and preventing water vapor from entering the charging column body 1 and damaging the controller 4. When the internal gear 36 rotates, it drives the first gear 67 to rotate, which in turn drives the control rod 65 to swing back and forth through the sliding column 66. The control rod 65 drives the connecting rod 63 to swing back and forth, which in turn drives the air guide plate 62 to swing back and forth through the fixed rod 64. This continuously switches the air blown out by the second fan 32, thereby increasing the airflow and improving the heat dissipation effect of the controller 4.

[0053] When not in use, the electric push rod 54 is activated, and the telescopic end of the electric push rod 54 extends, pushing the second pulley 55 upward, thereby releasing the pull rope 56. The direction of the pull rope 56 is changed by the third pulley 57, and under the action of the counterweight ring 53, the fireproof cloth 52 is pulled open, thereby protecting the charging column body 1. The fireproof cloth 52 is coated with waterproof paint to prevent rainwater from entering the interior of the charging column body 1. When the car is charging, if the charging column body 1 is damaged and the controller 4 catches fire, the pull rope 56 will be burned off, thereby releasing the counterweight ring 53 and opening the fireproof cloth 52, thereby preventing external oxygen from entering the interior of the charging column body 1, thus playing a role in extinguishing the fire and preventing the fire from spreading.

[0054] When the car needs charging, the electric scissor lift 22 is activated, which pushes out the closing plate 21. The electric scissor lift 22 opens, and the charging cable 26 is wound around the first pulley 23, thus effectively preventing the charging cable 26 from dragging on the ground. The knob 24 is turned out to facilitate the installation of the charging cable 26. The plug of the charging cable 26 is suspended on the bracket 27 for easy access, effectively preventing damage to the charging cable 26 and thus improving the service life of the charging cable 26.

[0055] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
