Description

Technical Field

[0001] The present application relates to the technical field of charging equipment, and in particular to a waterproof window and a charging pile. Background Art

[0002] With the rapid development of the electric vehicle industry, charging piles, as critical infrastructure supporting EVs, are attracting increasing attention for their performance and user experience. Charging piles are often installed outdoors and must withstand a variety of complex and changeable weather conditions, such as wind, rain, snow, and hail. In such circumstances, the protective design of charging piles becomes crucial. Venetian blinds, as a key component of charging piles, not only dissipate heat but also play a vital role in ensuring stable operation and enhancing the user experience.

[0003] However, the charging pile blinds that are widely used at present usually adopt a single-layer structure. The protective performance of single-layer blinds is limited, which can easily cause external impurities such as rainwater and dust to invade the interior of the charging pile, thereby affecting the normal operation of the equipment, increasing the risk of equipment failure, and even causing potential safety hazards.

[0007] Optionally, the exterior shutter is provided with a plurality of first blades in sequence along the vertical direction, the first blades are S-shaped blades, and the plurality of S-shaped blades are linked end to end.

[0008] Optionally, the S-shaped blade has a first bend portion and a second bend portion, the opening of the first bend portion faces away from the inner shutter, the opening of the second bend portion faces the inner shutter, and the vertical projections of the first bend portion and the second bend portion of two adjacent S-shaped blades overlap.

[0009] Optionally, the inner shutter is provided with a plurality of second blades at intervals along the vertical direction, and the second blades are arranged obliquely downward in a direction from the inner shutter to the outer shutter.

[0012] Optionally, at least one layer of protective net is provided between the outer shutter and the inner shutter.

[0013] Another aspect of an embodiment of the present application provides a charging pile, comprising a pile body having an air inlet and any one of the above-mentioned waterproof windows, wherein the waterproof window is installed at the air inlet.

[0014] Optionally, the charging pile further includes a fan, which is located between the inner blinds and the outer blinds of the waterproof window.

[0016] The beneficial effects of this application include:

[0017] This application provides a waterproof window and charging pile, comprising an outer blind, an inner blind, and a water guide trough. The outer blind and the inner blind are arranged horizontally with intervals between them. The intervals between the outer blind and the inner blind ensure that the outer blind is primarily responsible for shielding the majority of rainwater and dust, preventing large amounts of water and dust from entering the interior. The inner blind further enhances the protective function, improving the overall protection performance and ensuring that the remaining small amount of water and dust cannot pass through, thereby achieving a waterproof rating of IP55 and achieving more efficient multi-layered protection. In addition, the bottom of the inner blind is designed to be slightly higher than the bottom of the outer blind. This vertical height difference serves to guide water and dust, effectively controlling the flow of water and dust passing through the inner blind and directing them from the bottom of the inner blind to the bottom of the outer blind through the water guide trough, preventing water and dust from being trapped in the internal structure of the charging pile. This not only prevents the accumulation and retention of water and dust, but also reduces the risk of charging pile failure caused by excessive moisture and dust.

[0018] Overall, this waterproof window design significantly enhances the overall protection level through optimized structural connections and rational water flow guidance. It prevents most external moisture and dust from entering the charging pile. The coordinated operation of the internal and external louvers and the drainage function of the water guide trough ensure the long-term safe operation of the charging pile, significantly reducing the risk of malfunctions and safety hazards caused by rain, dust, and other factors.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application as claimed, but merely represents selected embodiments of the present application. It should be noted that, unless there is a conflict, the various features of the embodiments of the present application may be combined with each other, and the combined embodiments are still within the scope of protection of the present application.

[0028] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended only to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not necessarily mean that a component must be absolutely horizontal or overhanging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0031] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0032] In one aspect of the embodiments of the present application, a waterproof window is provided, which can be applied to a charging pile, such as Figure 1 As shown, the waterproof window comprises an outer louver 10, an inner louver 20, and a water guide trough 30. The outer louver 10 and the inner louver 20 are horizontally spaced apart at the air inlet of the charging station. Through their rational structural connection and arrangement, this waterproof window exhibits excellent waterproof performance, making it suitable for outdoor environments, especially those facing inclement weather conditions. The outer louver 10 and the inner louver 20 are horizontally spaced apart, forming a multi-layered protection system that effectively prevents rainwater from entering the equipment.

[0033] Specifically, the staggered arrangement of the outer and inner louvers 10 and 20 ensures that the outer louvers 10 primarily shield the interior from the majority of rain and dust, preventing significant amounts of water and dust from entering. The inner louvers 20 further enhance this protection, improving overall performance and preventing any remaining moisture and dust from entering. This ensures a waterproof rating of IP55, achieving a more efficient, multi-layered approach.

[0034] Secondly, the bottom of the inner louver 20 is designed to be slightly higher than the bottom of the outer louver 10. This vertical height difference guides water and dust, effectively controlling the flow of water and dust through the inner louver 20 and directing them through the water guide trough 30 from the bottom of the inner louver 20 to the bottom of the outer louver 10, preventing them from being trapped within the internal structure. This not only prevents the accumulation and retention of water and dust, but also reduces the risk of charging pile failures caused by excessive moisture and dust.

[0035] It should be understood that the introduction of the water channel 30 is crucial. Within the entire waterproofing system, the water channel 30 effectively directs water flow to the exterior. The connection between the inner and outer Venetian blinds 20, 10, is achieved through the water channel 30, which not only ensures smooth water drainage but also enhances the overall system's protective capabilities. This rational water flow guidance design ensures that the entire waterproof window system simultaneously meets the requirements for efficient operation in terms of both waterproofing and heat dissipation.

[0036] Overall, this waterproof window design significantly enhances the overall protection level through optimized structural connections and a rational water flow path. It prevents most external moisture and dust from entering the charging pile. The coordinated operation of the internal and external louvers 10 and the drainage function of the water channel 30 ensure the long-term safe operation of the charging pile, significantly reducing malfunctions and safety risks caused by rain, dust, and other factors.

[0037] Optionally, the exterior shutter 10 is provided with a plurality of first blades 11 in a vertical direction, wherein the first blades 11 are S-shaped blades, and the plurality of S-shaped blades are interlocked end to end. This design is not only beautiful but also has good functionality, especially in terms of waterproofing, dustproofing and air circulation.

[0038] Specifically, if Figure 2 As shown, the interlocking S-shaped blades allow each blade to fit tightly together, forming a continuous and seamless protective barrier. Compared to traditional straight or flat blades, the S-shaped structure offers a more complex geometry, making it difficult for foreign matter such as water and dust to enter the charging pile through the gaps between the S-shaped blades. The tight connection between the S-shaped blades also reduces the risk of water leakage, improving the protective performance of the entire shutter system and effectively reducing the impact of the external environment on the charging pile interior.

[0039] Secondly, the S-shaped blade design not only provides excellent protection but also excels in air circulation. The S-shaped curve allows air to flow freely between the blades, maintaining good ventilation and heat dissipation while preventing the intrusion of external impurities such as rainwater and dust. Because the S-shaped blades form multiple curved surfaces, water droplets slide down along the curved surfaces when they contact the blades, reducing the possibility of rainwater accumulating on the blade surface and further enhancing the waterproof effect.

[0040] Furthermore, the end-to-end S-shaped blade connection method can also enhance the overall structural strength. The multiple S-shaped blades arranged in sequence can not only ensure the overall stability of the exterior shutter 10, but also enable it to maintain its elasticity in the event of strong winds or impacts, thereby increasing its wind resistance.

[0041] Overall, the interlocking structure of the S-shaped blades can not only improve the overall protection level of the blinds, but also significantly improve the wind resistance and waterproofness of the blinds, ensuring that the charging pile can maintain normal operation under various severe weather conditions and extending the service life of the charging pile.

[0042] Optionally, the S-shaped blade has a first bend 111 and a second bend 112. The opening of the first bend 111 faces away from the inner louver 20, and the opening of the second bend 112 faces the inner louver 20. The vertical projections of the first bend 111 and the second bend 112 of two adjacent S-shaped blades overlap. This structural design can effectively block rain and dust from the outside while providing a certain air circulation path inside.

[0043] Specifically, if Figure 2 As shown, the opening of the first bend 111 faces the external environment. When rainwater contacts the blade, it flows downward along the curve of the first bend 111. At the same time, the opening of the second bend 112 faces away from the external environment and forms a curved guide path. After passing through the first bend 111, the water droplets slide along the back of the second bend 112 and eventually reach the first bend 111 of the next S-shaped blade. The opening of the first bend 111 and the back of the second bend 112 form a natural water flow path, effectively guiding rainwater by utilizing the curved structure of the blade. Because the S-shaped blades are arranged in multiple layers in the vertical direction, water droplets slide through the bends between each layer, avoiding the possibility of water droplets being retained or directly penetrating the gaps between the blades. Ultimately, the water droplets smoothly reach the bottom end of the external blind 10 along the multi-level conduction path, preventing water from entering the interior of the charging pile. This can not only ensure the long-term stable operation of the charging pile, but also reduce potential damage and corrosion problems caused by accumulated water. At the same time, this design also has a good self-cleaning effect, because the water flow will naturally carry away dust and impurities on the surface of the blade during the sliding process, further enhancing the protection effect.

[0044] In addition, the bends of two adjacent S-shaped blades overlap in projection in the vertical direction. This overlapping structure ensures that a barrier that provides both protection and ventilation can be formed between the two blades. The overlapping manner of the first bend 111 and the second bend 112 can increase the sealing between the blades, preventing external impurities such as rainwater and dust from passing through easily. At the same time, a channel for air circulation is reserved in the gap to ensure that the necessary heat dissipation and ventilation functions can be obtained inside the equipment. Moreover, since the projections of the bends in the vertical direction overlap with each other, the air will not be blown directly into the interior when passing through the gap, but will be guided by the curved design of the blades, gradually reducing the flow rate, thereby better achieving the effect of heat dissipation and ventilation.

[0045] During implementation, the molding and installation of the S-shaped blades requires precise manufacturing and alignment of each bend. High-precision mold manufacturing techniques ensure the geometrical consistency and dimensions of each first bend 111 and second bend 112. Each S-shaped blade is attached to the exterior window frame via a mechanical clip or other fastening device, ensuring proper alignment and overlap of adjacent S-shaped blade bends during installation, thus forming a continuous vertical protective barrier.

[0046] To sum up, the first and second bent portions 112 of the S-shaped blade can significantly improve the waterproof and dustproof performance of the waterproof window through precise structural design and overlapping connection, while also enhancing the heat dissipation and wind resistance of the waterproof window, thereby effectively ensuring the long-term stable operation of the charging pile in complex environments.

[0047] Optionally, the inner shutter 20 is provided with a plurality of second blades 21 spaced apart in the vertical direction, and the second blades 21 are arranged obliquely downward along the direction of the inner shutter 20 toward the outer shutter 10, so as to form an effective water flow guiding system, ensuring that even a small amount of rainwater passing through the S-shaped blades can slide down smoothly and be discharged, further preventing it from entering the interior of the charging pile.

[0048] Specifically, if Figure 3As shown, each second blade 21 is secured to the inner window frame at a predetermined angle using mechanical clips or other fixing devices, ensuring that water droplets can smoothly slide down to the bottom. This structural design not only ensures the stability of the second blade 21 but also allows it to maintain its tilt angle even when subjected to external pressure. The second blade 21 is tilted from the inner shutter 20 toward the outer shutter 10, allowing rainwater to slide outward along the inclined surface after passing through the S-shaped blades and contacting the second blade 21. This process increases the flow rate of rainwater and reduces its retention time, thereby reducing the risk of rainwater entering the charging station. As water droplets slide, influenced by the tilt angle, they flow smoothly along the second blade 21, ultimately reaching the bottom of the inner shutter 20. Furthermore, the water guide trough 30 is connected to the bottom of the inner shutter 20, forming a clear water flow channel, ensuring that water droplets are efficiently guided to the bottom of the outer shutter 10 and ultimately discharged to the external environment.

[0049] It should be noted that the inner window frame of the inner shutter 20 and the outer window frame of the outer shutter 10 can be connected by a housing 50. This housing 50 firmly secures the two layers of shutters together, forming a complete, enclosed structure that better protects against the ingress of rain, dust, and other contaminants. Sealing strips or waterproof adhesive tape are typically used at the ends of the housing 50 connecting the inner and outer window frames to further strengthen the tight connection between the housing 50 and the shutters and prevent water leakage caused by any minor gaps.

[0050] In summary, the design of the second blade 21 further enhances the IP rating of the inner louver 20, bringing it to the IP55 standard. The inclined surface of the second blade 21 effectively guides rainwater that has passed through the S-shaped blades to the bottom of the inner louver 20, where it flows through the water guide trough 30 toward the outer louver 10. This design not only prevents rainwater accumulation but also significantly reduces potential damage to the charging pile caused by moisture, ensuring safe and reliable operation in all weather conditions.

[0051] Optionally, the side wall of the water trough body 30 close to the outer shutter 10 has a first opening 32, and the water flow formed by the inner shutter 20 is sequentially conducted to the bottom end of the outer shutter 10 through the notch 31 and the first opening 32 of the water trough body 30.

[0052] Specifically, if Figure 4As shown, the second blades 21 of the inner louver 20 are tilted to guide the water downward. The notch 31 of the water trough 30 allows the water introduced from the inner louver 20 to enter the trough 30 smoothly. The sidewall of the trough 30, close to the outer louver 10, is provided with a first opening 32. The first opening 32 is connected to the bottom of the outer louver 10 through a precise connection, forming a water channel, ensuring that the water continues to move downward and flows to the bottom of the outer louver 10, where it is discharged to the external environment. The design of the water trough 30 ensures that water does not accumulate inside the charging pile, reducing the risk of water droplet retention and equipment corrosion.

[0053] The inclination angle and dimensions of the water channel body 30, the opening angle of the notch 31, and the position of the first opening 32 all require precise design and manufacturing to ensure smooth and continuous water flow through each part. Furthermore, the connection between the water channel body 30 and the outer blind 10 must be seamlessly fitted to form a complete water channel.

[0054] Optionally, the water guide trough body 30 is arranged in a stepped downward direction from the inner shutter 20 to the outer shutter 10 .

[0055] Specifically, the trough body 30 is screwed or welded to the inner window frame at one end and to the outer window frame at the other. Each step maintains a tight connection with its adjacent components. This stepped design prevents excessive tilt angles, allowing water to flow freely between each level of the trough body 30, ultimately reaching the bottom of the outer blind 10. This structural connection is not only stable and reliable, but also effectively prevents water leakage and seepage. After rainwater passes through the inner blind 20, it gradually slides downward along the stepped structure of the trough body 30. Due to the stepped design of the trough body 30, the water flow is naturally guided to the notch 31 of the next level at each level, ultimately converging at the lowest point and draining out through the bottom of the outer blind 10. The key to the stepped design is to control the speed and direction of the water flow, preventing rainwater from stagnating or backflowing in the trough body 30, thereby ensuring the smooth operation of the entire system.

[0056] It should be noted that the height difference of each step must be appropriately designed based on water flow and drainage speed to ensure that water flows gradually downward between levels. The connection points between the trough body 30 and the blinds must also be rigorously sealed to prevent leakage during water flow. Furthermore, during installation, the steps of the trough body 30 must be seamlessly connected to form a complete water flow guidance system.

[0057] Optionally, at least one protective net 40 is provided between the outer and inner louvers 10, 20. This design effectively enhances the overall protection of the device by adding a physical barrier. The net 40 not only acts as an insect screen, preventing dust, flying insects, and other external contaminants from entering the charging pile, but also further optimizes water flow management, enhancing the system's waterproofing.

[0058] Specifically, if Figure 5 As shown, the protective net 40 serves as a multifunctional barrier, which plays a dual protective role based on the physical properties of airflow and droplets. First, the protective net 40 blocks small particles such as flying insects and dust from entering the interior of the charging pile through a fine mesh structure. This process not only keeps the interior of the equipment clean, but also reduces the frequency of maintenance. Secondly, the protective net 40 can disperse the small amount of rainwater entering from the external blinds 10 and evenly divide it into small droplets. When the water droplets pass through the grid, the larger water flow is divided into multiple small droplets. These small droplets have lower mass and kinetic energy, and are therefore more susceptible to the influence of gravity and friction, thereby slowing down the speed of the water flow.

[0059] It should be noted that the material of protective mesh 40 is typically a weather-resistant metal mesh or high-strength fiber mesh. This material effectively blocks flying insects and dust while remaining durable even under prolonged exposure to outdoor conditions. Furthermore, the mesh size should be fine enough to effectively block external contaminants, but not too dense to prevent airflow. During device operation, protective mesh 40 not only provides effective protection but also does not negatively impact the device's heat dissipation performance.

[0060] Another aspect of the present invention provides a charging pile, comprising a pile body having an air inlet and any of the above-mentioned waterproof windows, the waterproof window being mounted at the air inlet. Since the charging pile employs the above-mentioned waterproof window, it also has the same beneficial effects as the waterproof window, and thus will not be further described here.

[0061] Optionally, the charging pile also includes a fan located between the inner and outer louvers 20 and 10 of the waterproof window. The waterproof window, mounted at the air inlet, effectively prevents rain and dust from entering. The fan, located between the inner and outer louvers 10, provides efficient heat dissipation through air circulation. This design not only elevates the charging pile's protection level to IP55, extending its lifespan, but also ensures its stability and reliability in extreme weather conditions.

[0062] Optionally, the waterproof window includes two layers of protective nets 40 , which are respectively arranged on opposite sides of the fan.

[0063] Specifically, the waterproof window's two layers of protective nets 40 are installed on the outside and inside of the fan, respectively. The inner layer of the protective net 40 is located between the inner louvers 20 and the fan, while the outer layer of the protective net 40 is located between the outer louvers 10 of the waterproof window and the fan. These two layers of protective nets 40 are firmly connected to the inner and outer window frames, ensuring they remain stable during long-term outdoor operation. The outer layer of the protective net 40 primarily intercepts rainwater, dust, and flying insects. Its fine mesh structure disperses water droplets and solid particles in the air, preventing them from directly entering the fan. The inner layer of the protective net 40 provides further protection. In the event that the outer layer of the net fails to completely intercept, the inner layer of the protective net 40 acts as a second barrier to ensure the cleanliness and safety of the equipment's interior.

[0064] The installation of the inner and outer protective nets 40 requires precise alignment to ensure a tight and seamless connection between the nets 40, the blinds, and the fan. The outer net 40 is typically made of a high-strength, corrosion-resistant material to withstand long-term outdoor exposure to wind and rain. The inner net 40 is constructed of lightweight metal or a weather-resistant synthetic material, focusing on ventilation and durability.

[0065] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
