Description

Technical Field

[0001] The utility model relates to the technical field of power supply waterproofing, in particular to a waterproof structure of an outdoor power supply interface. Background Art

[0002] The waterproof structure of the outdoor power interface means that the power interface used in the outdoor environment has a certain waterproof performance to protect the power interface from moisture intrusion and corrosion, to ensure that the outdoor power interface can still work normally under severe weather conditions, and to avoid moisture intrusion causing electrical failures, short circuits or other safety problems.

[0003] According to the publication number CN217158779U, a power interface waterproof device includes a power port and a charging port. A waterproof rubber pad is provided on the outer wall of the power port. The waterproof rubber pad is provided with a through hole that matches the power port. The through hole fits tightly with the power port. The utility model cooperates with the waterproof rubber pad and the dust cover to avoid the need to install two rubber pads during the production process to respectively provide waterproof and dustproof effects for the casing and the power cord, thus saving high costs. Moreover, the waterproof rubber pad and the dust cover are hinged through a hinge seat and are not easy to lose. By combining the above references, it is found that the existing outdoor power interface waterproof structure has at least the following problems:

[0004] 1. The power interface is usually equipped with a waterproof and dustproof cover, but some covers only cover the power interface. Especially when used outdoors, it is difficult to achieve complete waterproof and dustproof effects with just a cover, because there may be tiny gaps or gaps at the connection between the cover and the interface, which may cause moisture or impurities to penetrate;

[0005] 2. When the waterproof cover is used outdoors, due to the large temperature difference outdoors, high temperature may cause the material to soften, while low temperature may cause the material to become brittle. These factors may cause the cover to deform, thereby reducing its waterproof performance. In addition, a humid environment will also make the cover prone to corrosion, which will affect its service life and reduce the sealing effect of the power interface. Utility Model Content

[0006] The purpose of the utility model is to provide a waterproof structure of an outdoor power interface to solve the problems of the waterproof structure of the outdoor power interface proposed in the above background technology during use.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A waterproof structure for an outdoor power interface, comprising:

[0009] The protective shell is the waterproof structure of the outdoor power interface;

[0010] A charging port and an activity slot, both of which are provided on the outer surface of the protective shell;

[0011] The movable groove comprises a cover plate, a sealing ring and a protrusion;

[0012] A sealing frame fixed inside the charging port;

[0013] The cover plate is composed of an inner plate, a temperature-resistant layer and an anti-corrosion layer.

[0014] Preferably, the protective shell further comprises:

[0015] A water diversion trough is provided on both sides of the protective shell;

[0016] A rotating shaft, which is rotatably disposed inside the movable groove, and the cover plate is fixed to the outer surface of the rotating shaft;

[0017] The torsion spring is sleeved on both sides of the outer surface of the rotating shaft.

[0018] Preferably, the protective shell further comprises:

[0019] The protrusion is fixed on the outer surface of the cover plate;

[0020] The temperature-resistant layer is wrapped around the outer surface of the inner plate;

[0021] The anti-corrosion layer is applied on the outside of the temperature-resistant layer.

[0022] Preferably, the protective shell further comprises:

[0023] The torsion springs are provided in two groups, and the two ends of the torsion springs are respectively fixedly connected to the inner wall of the movable groove and the two sides of the cover plate.

[0024] Preferably, the protective shell further comprises:

[0025] The protrusions are arranged in multiple groups, and the protrusions are arranged at equal distances from top to bottom or from left to right.

[0026] Preferably, the protective shell further comprises:

[0027] The sealing ring is fixedly arranged on the bottom of the cover plate, and the sealing ring is inserted into the sealing frame.

[0028] Preferably, the protective shell further comprises:

[0029] The temperature-resistant layer is made of carbon fiber composite material, which is a lightweight, high-strength, high-rigidity, and high-heat-resistant material that can maintain stable performance in a high-temperature environment. At the same time, the carbon fiber composite material also has good low-temperature resistance and can still maintain good strength and rigidity in a low-temperature environment.

[0030] The embodiment of the utility model provides a waterproof structure of an outdoor power interface, which has the following beneficial effects:

[0031] 1. By setting a sealing frame, a sealing ring and a protrusion, when people do not need to plug in the charging connector, the sealing ring will be stuck in the inside of the sealing frame, thereby completely isolating the charging port from the outside. This design ensures the sealing of the charging port. At the same time, when external water droplets splash, they come into contact with the protrusion, forming a tiny groove, making it difficult for water droplets to stay on the surface of the cover, but flow down along the protrusion, effectively preventing moisture from entering the charging port, protecting the safe operation of the charging equipment, reducing the probability of gaps, and improving the sealing safety of the charging port.

[0032] 2. By setting a heat-resistant layer and an anti-corrosion layer, the heat-resistant layer is made of carbon fiber composite materials, which has high strength, high rigidity and high heat resistance, and can ensure the stable performance of the cover in an external high-temperature environment. At the same time, the carbon fiber composite material also has good low-temperature resistance, ensuring that the cover will not become brittle or crack in an external low-temperature environment. The anti-corrosion layer uses waterproof coating, which has good water resistance and corrosion resistance, and can effectively prevent the cover from being damaged by moisture and corrosive media. The combination of these structures can extend the service life of the cover and improve its reliability, thereby ensuring the normal use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0040] Example: Figure 1 As shown, a waterproof structure of an outdoor power interface includes: a protective shell 1, which is the main body of the waterproof structure of the outdoor power interface. The protective shell 1 can effectively prevent moisture from penetrating into the interior of the power interface by adopting waterproof design and materials, so as to avoid moisture from damaging the internal circuits and components of the interface and ensure the normal operation of the power interface. A water diversion groove 2 is opened on both sides of the protective shell 1 to divert rainwater to both sides to avoid rainwater from entering the interior of the power interface, thereby ensuring the normal operation of the interface. A cover plate 3 is fixed on the outer surface of the rotating shaft 7. The cover plate 3 closes the entire charging port 5, which can effectively prevent dust, dirt, liquid, etc. from entering the internal space of the charging port 5, so as to avoid moisture from damaging the internal circuits and components of the interface and ensure the safety of the power interface. A protrusion 4 is fixed on the outer surface of the cover plate 3. The protrusion 4 can change the behavior of water droplets on the surface, making it difficult for them to stay on a flat surface. By forming tiny grooves or changing surface tension, water droplets will flow down along the protrusion 4 structure instead of staying on the cover plate 3.

[0041] like Figure 2 and Figure 3 As shown, the movable groove 6 and the charging port 5 are both opened on the outer surface of the protective shell 1, and the movable groove 6 is located above the charging port 5. The movable groove 6 facilitates the rotation space of the rotating shaft 7. The charging port 5 is connected to the interface of the power supply device. The protective shell 1 plays a role in protecting the equipment in the outdoor environment, and can resist the erosion of the equipment by the external environment such as wind, sand, rain, dust, etc. The charging port 5 is arranged inside the protective shell 1, which can avoid the charging port 5 from being directly exposed to the external environment, and reduce the risk of damage or corrosion of the charging port 5 by external factors.

[0042] like Figure 4As shown, it includes: the cover plate 3 is composed of an inner plate 13, a heat-resistant layer 11 and an anti-corrosion layer 12. The inner plate 13 is the main load-bearing component of the cover plate 3, which provides structural stability and strength. The heat-resistant layer 11 is wrapped on the surface of the inner plate 13, and the anti-corrosion layer 12 is applied to the outside of the heat-resistant layer 11. The heat-resistant layer 11 is made of carbon fiber composite material. The density of carbon fiber composite material is lighter than that of traditional metal materials such as steel, which can effectively reduce the weight of the entire structure. The carbon fiber composite material has good heat resistance, can maintain stable performance in a high temperature environment, and is not easy to deform. The carbon fiber composite material also has good low-temperature resistance, can still maintain good strength and rigidity in a low temperature environment, and is not easy to become brittle. The anti-corrosion layer 12 is made of materials such as polymers and acrylic acid, which has good water resistance, can effectively block moisture penetration, and prevent corrosive media from entering the surface of the protected object, thereby extending the service life of the protected object. The anti-corrosion layer 12 material has good adhesion to the surface of the protected object and is not easy to peel off or fall off, ensuring the durability and stability of the anti-corrosion layer. The two groups are used together to improve the service life of the cover plate 3.

[0043] Working principle: personnel connect the device to the outdoor power interface and install it. When charging is needed, the cover plate 3 is rotated from the inside of the charging port 5 through the rotating shaft 7, and its torsion spring 9 is twisted. Then the personnel inserts the plug into the charging port 5. When not in use, the cover plate 3 re-seals the charging port 5 under the reset of the torsion spring 9, and its sealing ring 10 is stuck in the sealing frame 8 to improve the sealing of the charging port 5. At the same time, when it rains outdoors, raindrops flow along the water diversion groove 2 to the two sides of the structure. The protrusion 4 can change the behavior of water droplets on the surface, making it difficult for them to stay on the flat surface. By forming tiny grooves or changing the surface tension, water droplets will flow along the protrusion 4 structure and will not stay on the cover plate 3. The inner plate of the cover plate 3 is wrapped by the heat-resistant layer 11, which can ensure the stability of the cover plate 3 in high or low temperature outdoor environments. Secondly, the anti-corrosion layer 12 has good water resistance and corrosion resistance, which can effectively prevent the cover plate 3 from being damaged by moisture and corrosive media, thereby extending the service life of the cover plate 3.

[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
