Description

Technical Field

[0001] This utility model relates to the field of outdoor car charging pile technology, specifically an outdoor car charging pile with a water-blocking structure. Background Technology

[0002] With the increasing popularity of new energy vehicles, outdoor car charging stations need to withstand complex environments such as rain, snow, salt spray, and high and low temperature cycles over long periods. The quality of their water-blocking performance directly determines the safety and lifespan of the equipment. Existing outdoor car charging stations generally adopt a passive comprehensive water-blocking method, with silicone sealing rings and water-blocking strips used to reinforce the seal at the seams of the outer shell, water-blocking covers for the charging interface, and drainage holes at the bottom to drain accumulated water. However, during operation, outdoor car charging stations generate more heat internally, which needs to be released. Existing outdoor car charging stations use louvers on the casing to allow fans to draw in air and blow it onto the heating module. However, these louvers have openings that connect to the inside of the casing. In rainy, snowy, or windy weather, the water-blocking performance of the louvers in traditional outdoor car charging stations will decrease, failing to prevent rainwater from entering the casing. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an outdoor car charging pile with a water-blocking structure, thereby solving the problem mentioned in the background art that the casing of outdoor car charging piles does not have a water-blocking structure and has poor water resistance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an outdoor car charging pile with a water-blocking structure, including a housing, wherein the housing is provided with louvers for air to enter the housing and fan blades in the louvers, and a fan for drawing in air is provided in the housing corresponding to the fan blade position, the fan blades including a first limiting part, a second limiting part and a guiding part, the first limiting part for blocking rainwater entering the housing along the guiding part, the second limiting part for blocking rainwater outside the housing, and the guiding part for guiding the rainwater blocked by the first limiting part to drain out of the housing, one end of the guiding part being connected to the first limiting part and the other end being connected to the second limiting part, and a channel is formed between two adjacent fan blades.

[0005] As a further improvement of this utility model, a number of vertical bars are evenly distributed on the upward-facing side wall of the guide part. One end of each vertical bar is connected to the first limiting part, and the other end is connected to the second limiting part. A guide groove is formed between two adjacent vertical bars.

[0006] As a further improvement of this utility model, the surface of the vertical rail is a smooth surface, and the inner wall of the guide groove is also a smooth surface.

[0007] As a further improvement of this utility model, the first limiting part is L-shaped and has a notch, which can be used to block some dust from entering the chassis.

[0008] As a further improvement of this utility model, the second limiting part is arranged at the same horizontal line as the outer side wall of the chassis.

[0009] As a further improvement of this utility model, the louvers are rotatably connected to the housing via a rotating shaft, and the louvers and the housing are detachable.

[0010] Compared with existing technologies, this utility model provides an outdoor car charging pile with a water-blocking structure, which has the following advantages: Through the coordinated design of the first limiting part, the second limiting part, and the guide part of the fan blades, it achieves double water blocking and efficient drainage, adapting to rainy outdoor environments. The first limiting part blocks rainwater entering the casing along the guide part, while the second limiting part directly blocks rainwater outside the casing, precisely avoiding the intrusion path of rainwater with this double barrier. The guide part not only connects the two limiting parts to form a complete water-blocking structure but also promptly drains the rainwater blocked by the first limiting part, preventing water accumulation. Simultaneously, the channel formed by adjacent fan blades, in conjunction with the fan, ensures normal airflow into the casing for heat dissipation, with water blocking and heat dissipation functions not interfering with each other. This structure is simple and compatible with existing casing louvers, eliminating the need for additional complex water-blocking components. It is highly practical, effectively protecting the internal components of the charging pile, extending its outdoor service life, and reducing maintenance costs. Attached Figure Description

[0015] As shown in the figure, to achieve the above-mentioned objective, this utility model provides an outdoor car charging pile with a water-blocking structure, including a housing 1. The housing 1 is provided with louvers 2 for air to enter the housing 1 and fan blades 3 in the louvers 2. A fan 4 for drawing in air is provided in the housing 1 corresponding to the fan blades 3. The fan blades 3 include a first limiting part 5, a second limiting part 6, and a guiding part 7. The first limiting part 5 is used to block rainwater entering the housing 1 along the guiding part 7. The second limiting part 6 is used to block rainwater outside the housing 1. The guiding part 7 is provided to guide the rainwater blocked by the first limiting part 5 to drain out of the housing 1. One end of the guiding part 7 is connected to the first limiting part 5, and the other end is connected to the second limiting part 6. A channel 8 is formed between two adjacent fan blades 3.

[0016] In implementation, this solution includes a chassis 1, which serves as the mounting carrier for the entire charging pile and houses the internal electrical components. Louvers 2 are machined on the side wall of chassis 1, and several fan blades 3 are installed within the louvers 2. The louvers 2 allow external air to enter the chassis 1, aiding in ventilation and heat dissipation. Inside chassis 1, a fan 4 is fixedly installed corresponding to the fan blades 3. A conventional axial flow fan 4 can be used. During operation, it generates suction, drawing external air into the chassis 1 through the channels 8 between the fan blades 3 to dissipate heat from the electrical components. The fan blades 3 are the core water-blocking components. Each fan blade 3 is integrally formed with a first limiting part 5, a second limiting part 6, and a guide part 7. All three can be made of the same metal material, resulting in a stable structure and good waterproof performance. The first limiting part 5 is fixedly connected to one end of the guide part 7, and the other end of the guide part 7 is connected to the second limiting part 6, forming a complete fan blade 3 body. Air channels 8 are formed between adjacent fan blades 3. The first limiting part 5 primarily blocks rainwater attempting to enter the chassis 1 along the guide part 7, reducing the probability of rainwater inflow. The second limiting part 6 blocks rainwater from outside the chassis 1, reducing the possibility of splashing onto the inside of the fan blades 3. The guide part 7 is inclined and has a drainage structure, which can guide the rainwater blocked by the first limiting part 5 to the outside of the chassis 1, preventing accumulation. The entire structure does not require many additional components, and achieves both water blocking and ventilation functions through the fan blades 3 themselves, making it convenient to operate and highly practical.

[0017] As an improved specific implementation, a plurality of vertical bars 9 are evenly distributed on the upward-facing side wall of the guide part 7. One end of the vertical bar 9 is connected to the first limiting part 5, and the other end is connected to the second limiting part 6. A guide groove 10 is formed between two adjacent vertical bars 9.

[0018] In this design, several vertical bars 9 are evenly distributed on the upward-facing side wall of the guide section 7. The number of bars 9 can be reasonably set according to the length of the guide section 7, ensuring uniform spacing as much as possible. One end of each bar 9 is fixedly connected to the first limiting part 5, which can be integrally formed with the guide section 7, and the other end is connected to the second limiting part 6, so that the three form a stable whole. A guide groove 10 is naturally formed between adjacent bars 9, and the extension direction of the guide groove 10 is basically consistent with the drainage direction of the guide section 7. When the first limiting part 5 blocks the rainwater flowing along the guide section 7, the rainwater can flow into the guide groove 10. Guided by the guide groove 10, it can be discharged from the casing 1 more accurately and quickly, reducing rainwater overflow and further improving the water-blocking effect. At the same time, the bars 9 can enhance the structural strength of the guide section 7, reduce the probability of deformation caused by outdoor wind and rain erosion, and extend the service life of the fan blade 3.

[0019] As an improved specific implementation, the surface of the vertical bar 9 is a smooth surface, and the inner wall of the guide groove 10 is also a smooth surface.

[0020] In this implementation, the outer surface of the vertical rail 9 is polished to a smooth surface to minimize protrusions and depressions, reducing the probability of rainwater accumulation. Simultaneously, the inner wall of the guide channel 10 undergoes the same polishing process to ensure no obvious burrs or rough surfaces, reducing rainwater flow resistance and allowing rainwater to drain more smoothly from the casing 1, further improving water-blocking efficiency. Furthermore, the smooth surface facilitates subsequent cleaning and maintenance, and to some extent prevents dust and debris from adhering to the surface of the vertical rail 9 and the inner wall of the guide channel 10, reducing the impact of blockage in the guide channel 10 on rainwater drainage and helping to ensure the long-term stable operation of the charging pile.

[0021] As an improved specific embodiment, the first limiting part 5 is L-shaped and has a notch 11, which can be used to block some dust from entering the casing 1.

[0022] In implementation, the first limiting part 5 has an L-shaped structure, which can be formed by bending metal sheets, resulting in a simple and relatively stable structure. The L-shaped first limiting part 5 has a notch 11 facing outwards from the casing 1, with the opening direction opposite to the air inlet direction. When the fan 4 draws in external air, the air enters through the channel 8 between adjacent fan blades 3. Some dust in the air will impact the notch 11 under the action of airflow, and the notch 11 can block the dust to a certain extent, reducing the amount of dust entering the casing 1 and lowering the risk of dust adhering to electrical components and affecting their working performance. At the same time, the L-shaped structure can further enhance the water-blocking effect. When rainwater flows along the guide part 7, it will be blocked by the L-shaped limiting surface, making it difficult for it to enter the interior of the casing 1.

[0023] As an improved specific embodiment, the second limiting part 6 is arranged at the same horizontal line as the outer side wall of the chassis 1.

[0024] During implementation, this solution adjusts the second limiting part 6 to the same horizontal line as the outer wall of the casing 1, making the outer surface of the second limiting part 6 roughly flush with the outer wall of the casing 1, reducing protrusions and depressions. During installation, shims can be placed at the connection between the fan blade 3 and the casing 1, or the tightness of the connecting bolts can be adjusted to ensure flatness as much as possible. This design reduces the accumulation of rainwater and dust on the protruding second limiting part 6, and also reduces the probability of water accumulation due to depressions, thus reducing rainwater buildup and improving water resistance. Furthermore, the flush design makes the charging pile more aesthetically pleasing and facilitates the installation and removal of the louvers 2, making operation convenient.

[0025] As an improved specific implementation, the louver 2 and the housing 1 are rotatably connected by a rotating shaft 12, and the louver 2 and the housing 1 are detachable.

[0026] This solution offers two implementation methods: First, the louvers 2 and the housing 1 are rotatably connected via a rotating shaft 12. The rotating shaft 12, made of stainless steel, is fixedly installed on the sides of the housing 1 corresponding to the louvers 2. The louvers 2 have shaft holes on both sides, allowing the louvers 2 to rotate and open / close. The louvers 2 are also detachable; one end of the rotating shaft 12 has a latch that engages with the side wall of the housing 1. To disassemble, press the latch to release it from the side wall, allowing the louvers 2 to be removed for easy maintenance. Second, the rotating shaft 12 is bolted to the housing 1, with both ends detachably connected to the side wall of the housing 1. The louvers 2 have matching bushings on both sides, which fit onto the rotating shaft 12 to allow rotation. To disassemble, simply unscrew the bolts to remove the rotating shaft 12 and the louvers 2, making the operation convenient.

All technical solutions falling within the scope of this utility model's concept are within its protection scope.
