Description

Technical Field

[0001] This utility model belongs to the field of charging pile technology, specifically relating to a waterproof vent device and a charging pile equipped with the vent device. Background Technology

[0002] With the popularization of new energy vehicles, charging piles, as an important supporting facility, have seen rapid industry development, and various charging products have matured. In the design and use of charging piles, product quality and safety are receiving increasing attention. To ensure the normal operation of charging piles and prevent malfunctions caused by internal overheating, charging piles are typically equipped with vents to promote air circulation and achieve heat dissipation.

[0003] However, during rain, rainwater can easily enter the charging station through the vents, leading to a series of safety hazards and equipment malfunctions. Once water enters the charging station, it can easily cause a short circuit, resulting in circuit failure and, in severe cases, even an explosion, causing personal injury and property damage. Therefore, vents are usually equipped with rainwater-blocking devices. Currently, most mainstream charging stations have IPX4 waterproof ratings for their vents, which can prevent splashing water from any direction from entering the charging station and can block ordinary rainwater.

[0004] However, in rainy regions such as Southeast Asia, heavy rainstorms are frequent and intense, with higher rainfall per unit time. Charging stations exposed to a humid environment for extended periods not only increase the risk of rainwater entering through vents, but also mean that IPX4-rated vents cannot withstand the high-intensity water flow and large volume of water from storms, causing damage, performance degradation, and even affecting the normal operation of the equipment.

[0005] Therefore, it is very important to improve the waterproof capability of the charging pile's air vent device. Utility Model Content

[0053] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0054] Example 1:

[0055] This embodiment provides a waterproof vent device suitable for installation at the ventilation opening of a charging pile, which can dissipate heat while preventing external water from entering the charging pile;

[0056] In this embodiment, the airflow direction of the waterproof vent device is horizontal, and the height direction of the waterproof vent device is parallel to the vertical direction.

[0057] like Figure 1 and Figure 2 As shown, the waterproof vent device includes: a waterproof vent assembly 1 and an inner waterproof drainage assembly 3;

[0058] The inner waterproof drainage component 3 is installed on the waterproof vent component 1, together forming a double-layer louvered waterproof structure; when the waterproof vent device is working, the airflow passes sequentially through the inner waterproof drainage component 3 and the waterproof vent component 1 and is discharged to the outside of the charging pile. Figure 2 (The airflow moves from right to left);

[0059] Specifically, the waterproof vent assembly 1 includes: a first housing and multiple blades;

[0060] Multiple blades are arranged at one end of the first outer shell near the inner waterproof and drainage component 3, and are evenly spaced along the height direction of the first outer shell; each blade is inclined downward, that is, the end of the blade away from the inner waterproof and drainage component 3 is lower than the end of the blade near the inner waterproof and drainage component 3.

[0061] The first outer shell has a drain outlet 101 at one end near the inner waterproof and drainage component 3; the drain outlet 101 is located below the bottommost blade;

[0062] The bottom surface 102 of the first outer shell can be either a horizontal surface or an inclined surface. When the bottom surface 102 of the first outer shell is an inclined surface, the end of it that is away from the inner waterproof and drainage component 3 is lower than the end that is close to the inner waterproof and drainage component 3. The inclined surface can drain the liquid and prevent water from accumulating inside the first outer shell.

[0063] The waterproof vent assembly 1 forms the first waterproof structure of the waterproof vent device;

[0064] The inner waterproof and drainage component 3 includes: a second outer shell and multiple water-repellent plates 301;

[0065] The second housing is mounted on the first housing; as an example, the waterproof vent device also includes: a sealing gasket 4; the sealing gasket 4 is disposed at the junction of the second housing and the first housing, thereby improving the sealing performance between the inner waterproof drainage component 3 and the vent component 1;

[0066] Multiple water-blocking plates 301 are disposed at the end of the second outer shell away from the waterproof vent assembly 1 (parallel to the height direction of the second outer shell) and are evenly spaced along the height direction of the second outer shell; each water-blocking plate 301 is inclined downward, that is, the end of the water-blocking plate 301 near the waterproof vent assembly 1 is lower than the end of the water-blocking plate 301 away from the waterproof vent assembly 1; as an example, each water-blocking plate 301 is a bent structure, thereby improving the structural strength of the water-blocking plate 301; each water-blocking plate 301 is integrally formed from plate A and plate B, one end of plate B is connected to the end of the second outer shell away from the waterproof vent assembly 1, and the other end is connected to plate A; the junction of plate A and plate B forms an angle, constituting a bent structure; let the angle formed by plate A and the height direction of the second outer shell be angle a, and the angle formed by plate B and the height direction of the second outer shell be angle b; angle b is 30° to 45°; angle a is less than angle b and the difference is not less than 5°.

[0067] The second housing is provided with a water baffle 302 at the end away from the waterproof vent assembly 1; the water baffle 302 is located below the bottom water baffle 301; the top of the water baffle 302 is higher than the top of the drain 101, forming a barrel effect, so that the liquid inside the second housing is discharged through the drain 101.

[0068] The bottom surface 303 of the second housing can be either a horizontal surface or an inclined surface; when the bottom surface 303 of the second housing is an inclined surface, the end of it near the waterproof vent assembly 1 is lower than the end away from the waterproof vent assembly 1, and the inclined surface forms a drainage for liquid to prevent water from accumulating inside the second housing.

[0069] The bottom surface 303 of the second outer shell, the drain outlet 101 and the bottom surface 102 of the first outer shell form a drain channel, through which the liquid inside the second outer shell is discharged to the outside of the waterproof vent device.

[0070] As an example, the waterproof vent device further includes: one or more fans 2;

[0071] The blower 2 is installed at one end of the first outer shell near the inner waterproof and drainage component 3, and is enclosed within the second outer shell; multiple blowers 2 are evenly spaced along the height direction of the first outer shell; the end of the first outer shell near the inner waterproof and drainage component 1 is provided with several through holes that correspond one-to-one with the blowers and are coaxial; the airflow direction of the blower 2 is opposite to the water flow direction, thereby blocking the water flow from entering; at the same time, the air inlet end of the blower 2 ( Figure 2 (middle right) and air outlet ( Figure 2 The pressure difference between the middle and left sides can prevent water from flowing back from the air outlet into the interior of the fan 2, so that the fan 2 can form another waterproof structure between the inner waterproof drainage component 3 and the waterproof air outlet component 1, which is a double-layer louvered waterproof structure, further improving the waterproof effect; in this embodiment, the fan 2 is preferably an IP68 axial flow fan, which can avoid damage to the fan 2 when it is immersed in water in heavy rain, thereby improving the overall stability of the waterproof air outlet device;

[0072] When the inner waterproof drainage component is preferably an IPX4 louver and the fan is an IP68 axial flow fan, the protection level of the waterproof air outlet device can reach IPX5, which can withstand higher water flow and stronger water flow impact.

[0073] Working principle:

[0074] When rainwater passes through the waterproof vent assembly 1, the downward-sloping blades can block some of the rainwater while reducing the impact force of the rainwater passing through the waterproof vent assembly 1.

[0075] When rainwater enters the inner waterproof and drainage component 3, the downward-sloping water baffle 301 can effectively block the rainwater, and the rainwater flows along the water baffle 301 to the bottom of the second shell.

[0076] Water at the bottom of the second housing flows out along the bottom surface 303 of the second housing, the drain outlet 101 and the bottom surface 102 of the first housing, thereby effectively improving the waterproof capability of the air vent device.

[0077] Based on this, the fan 2 blows the internal airflow outward, which not only achieves heat dissipation, but also forms a waterproof structure between the double-layer louvered waterproof structure, which can prevent rainwater from entering the inner waterproof drainage component 3, further improving the waterproof capability of the air outlet device.

[0078] Example 2:

[0079] This embodiment provides a charging pile, wherein the air vent of the charging pile is provided with a waterproof air vent device as described in Embodiment 1, thereby improving the waterproof capability of the charging pile and preventing water from entering the interior of the charging pile.

[0080] Specifically, the waterproof air vent assembly 1 is installed at the air vent of the waterproof air vent device, and the inner waterproof drainage assembly 3 is located inside the electrical equipment.

[0081] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
