Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile with efficient heat dissipation in rainy days. Background Technique

[0002] A charging pile refers to a charging device that provides energy replenishment for electric vehicles. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations. It can charge various models of electric vehicles according to different voltage levels.

[0003] In the prior art, the content of a Chinese utility model with the publication number: CN219360860U, a fast charging, efficient heat dissipation and energy-saving charging pile, includes a heat dissipation component. The heat dissipation component includes fan blades, a housing, a protection plate, an intake fan, a servo motor, a turntable, a fan, and an exhaust pipe. When the plug on the side of the charging gun is pulled out during user charging, the induction switch will automatically turn on and energize the heat dissipation component. After the heat dissipation component is energized, the servo motor automatically starts to drive the turntable to rotate, thereby driving the fan blades and the two fans on the upper part to rotate. The hot air dissipated inside the housing is blown upward by the fans and the fan blades, and the external fresh air is inhaled into the housing through the intake fan. After the hot air rises, the hot air is inhaled into the exhaust pipe by the exhaust fan and discharged. According to the principle of hot air rising, the discharged hot air is effectively prevented from being inhaled again by the bottom intake fan, improving the heat dissipation efficiency, thereby preventing damage to internal electronic components caused by excessive temperature and improving the service life of the charging pile.

[0004] Although the above technical solution speeds up the air flow rate through the principle of hot air rising for heat dissipation, during the long-term heat dissipation use of the charging pile, a large amount of dust will be adsorbed into the charging pile. The dust will affect the service life of the charging pile. At the same time, in rainy days, humid air will enter the interior of the charging pile, which will cause damage to the charging pile. Therefore, we need to propose a charging pile with efficient heat dissipation in rainy days. Content of the Utility Model

[0005] The purpose of the utility model is to provide a charging pile with efficient heat dissipation in rainy days, which is convenient for filtering the air introduced into the charging pile to avoid dust entering the charging pile and damaging electronic components. At the same time, it is convenient to clean the dust on the filtering structure, improve the air circulation efficiency, ensure the heat dissipation effect of the charging pile, and is convenient for drying the humid air in rainy weather, improving the dryness of the air, thereby reducing the impact on the charging pile during air circulation and heat dissipation, so as to solve the problems raised in the above background technique.

Detailed Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, the utility model provides a technical solution: a rain - day efficient heat - dissipating charging pile, including a charging pile body 1. Air inlet holes 11 are opened at both lower ends of the charging pile body 1. One end of the air inlet hole 11 located outside the charging pile body 1 is communicated with an air inlet cover 2, and one end of the air inlet hole 11 located on the inner wall of the charging pile body 1 is communicated with a diversion cover 6. Semiconductor refrigerators 7 are arranged on both sides of the inner cavity of the diversion cover 6. A cleaning mechanism 8 and a filter screen 10 are installed in the inner cavity of the air inlet cover 2. Charging guns 4 are installed on both sides of the charging pile body 1 adjacent to the two air inlet holes 11;

[0023] The cleaning mechanism 8 includes a cleaning component and a gas guide plate 811 installed on the cleaning component. Multiple jet nozzles 812 are arranged on one side of the gas guide plate 811. The other side of the gas guide plate 811 is communicated with a gas guide hose 810. The air inlet end of the gas guide hose 810 penetrates through the diversion cover 6 and is communicated with an air pipe 89. The air inlet end of the air pipe 89 is communicated with the air outlet end of an air pump 88.

[0024] The cleaning component includes a driving motor 81 and a reciprocating lead screw 84. The output shaft of the driving motor 81 is in transmission connection with a rotating shaft 82. One end of the rotating shaft 82 is fixedly connected with a driving gear 83. One end of the reciprocating lead screw 84 penetrates through the air inlet cover 2 and is fixedly connected with a driven gear 85 meshing with the driving gear 83. The other end of the reciprocating lead screw 84 is in threaded connection with a moving plate 87 for installing the gas guide plate 811. By driving the driven gear 85 through the driving gear 83, the reciprocating lead screw 84 drives the moving plate 87 to move reciprocally, so as to blow the dust on the filter screen 10 by the jet nozzles 812.

[0025] A guide rod 86 for guiding the sliding of the moving plate 87 is fixedly connected to the inner cavity of the air inlet cover 2. The guide rod 86 is arranged parallel to the reciprocating lead screw 84. The plane formed by the reciprocating lead screw 84 and the guide rod 86 is arranged parallel to the filter screen 10. The reciprocating lead screw 84 facilitates driving the moving plate 87 to move reciprocally, and the guide rod 86 improves the stability of the reciprocating movement of the moving plate 87.

[0026] Multiple anti - impurity grid bars 9 are arranged at the air inlet end of the air inlet cover 2. The multiple anti - impurity grid bars 9 are arranged at equal intervals. A protective cover 3 is arranged on one side of the air inlet cover 2. The protective cover 3 facilitates waterproofing of the driving gear 83 and the driven gear 85, avoiding rain erosion and reducing the service life.

[0027] The air pump 88 is installed at the bottom of the charging pile body 1. The air pump 88 is arranged directly below the diversion cover 6. An upward air hole 61 is opened on the upper surface of the diversion cover 6. The upward air hole 61 on the diversion cover 6 facilitates upward diversion of the dried and dust - removed air, so as to discharge the heat in the charging pile body 1 by the rising of hot air.

[0028] A rain shield 5 is installed on the upper surface of the charging pile body 1. A rectangular groove 51 is formed on the lower surface of the rain shield 5. A support plate 52 and multiple groups of support blocks 53 are fixedly connected to the bottom of the rectangular groove 51, which improves the installation stability of the rain shield through the support plate 52 and the support blocks 53.

[0029] Multiple groups of air outlet holes 12 communicating with the rectangular groove 51 are formed on the upper surface of the charging pile body 1. The cross-section of the rectangular groove 51 is larger than that of the upper surface of the charging pile body 1. The air blown out of the air outlet holes 12 is conveniently diverted through the rectangular hole, so that the discharged heat dries the surface of the charging pile body 1.

[0030] During use, a suction fan (not shown in the figure) is arranged in the diversion cover 6 to introduce external air into the charging pile body 1 through the filter net 10. The anti-impurity grid bars 9 prevent large-particle impurities from entering, and the filter net 10 prevents dust from entering the inside of the charging pile body 1 and affecting the electronic devices. When the air passes through the filter net 10 and then passes through the diversion cover 6, the semiconductor refrigerator 7 controls the dried air to enter the charging pile body 1 through the upper air flow holes 61, thus facilitating the diversion of the dried air. The dried air cools and dissipates heat inside the charging pile body 1, and the dried air discharges the heat inside the charging pile body 1 through the air outlet holes 12. Furthermore, through the arrangement of the rectangular groove 51, the air flow blows on the outer surface of the charging pile body 1, thus facilitating the drying of the surface of the charging pile body 1, avoiding the surface of the charging pile body 1 being wet on rainy days, and improving the safety of use. When cleaning the filter net 10, the driving motor 81 drives the driving gear 83 to engage with the driven gear 85 on the reciprocating lead screw 84, so as to drive the moving plate 87 to reciprocate along the guide rod 86 through the reciprocating lead screw 84. At the same time, the air pump 88 is started, so that the compressed gas blows the dust on the filter net 10 out through the paint spraying ports on the air guide plate 811, thus improving the cleaning efficiency of the filter net 10, ensuring the air circulation efficiency, and improving the heat dissipation efficiency of the charging pile body 1.
