Description

Technical Field

[0002] With the rapid development of the new energy vehicle industry, the number and usage frequency of charging piles are constantly increasing, making the protection of charging interfaces increasingly prominent. Existing charging interface protection devices generally adopt simple protective cover structures, which have many shortcomings in practical use. Traditional protective covers often use a single-layer structure design, resulting in poor sealing performance and susceptibility to rainwater and dust corrosion; the opening and closing mechanisms of the protective covers are simple in design, easily becoming loose or deformed after a period of use; the connection method between the protective cover and the charging pile is limited, making maintenance and replacement inconvenient; and improper selection of sealing materials for the protective devices leads to aging and damage after frequent use. These problems seriously affect the safety and lifespan of charging equipment, especially in harsh outdoor environments. Existing technological solutions mainly focus on increasing the thickness of the protective cover and improving the material of the sealing strip, but these improvements have limited effectiveness and fail to fundamentally solve the problems of poor protective performance and short service life.

[0042] The following is a specific application scenario of this utility model: The integrated charging interface protection device for charging piles of this utility model adopts the following specific structural design: The protective shell is made of 304 stainless steel, with a wall thickness of 2.5 mm, in a cylindrical structure, 180 mm high and 120 mm in diameter. The fixed base is made of aluminum alloy, including an 8 mm thick base plate and a 60 mm high support frame, with 8 mounting holes of 10 mm diameter evenly arranged on the base plate. The swing baffle is made of ABS engineering plastic, in a 120-degree fan shape, 4 mm thick, with a 3 mm wide nitrile rubber sealing strip embedded in the arc edge. The sliding guide rail is made of 304 stainless steel profile, with a T-shaped cross-section, a guide rail body width of 15 mm, a height of 25 mm, an internal groove width of 8 mm, and a 0.8 mm thick polytetrafluoroethylene anti-friction strip inlaid on the inner wall of the groove. The protective cover is injection molded from PC material, with a thickness of 3 mm, honeycomb reinforcing ribs on the inner side with a height of 2 mm, a grid spacing of 10 mm, and an anti-slip texture depth of 0.5 mm on the outer surface. Both the sealing ring and gasket are made of nitrile rubber with a Shore hardness of 60, with cross-sectional diameters of 3 mm and 4 mm respectively. The drive linkage is made of 304 stainless steel with a diameter of 6 mm, and nylon reinforcing sleeves with an outer diameter of 12 mm are fitted at both hinge points. The limiting block and limiting groove are made using precision casting technology, and the opening angle of the limiting groove is 130 degrees to ensure that the swing baffle's range of motion is within a safe range. All metal fasteners are made of 304 stainless steel, and the main bolts are M8 specification. The specific dimensional parameters in this embodiment are determined based on the size of common charging interfaces and can be appropriately adjusted according to actual application requirements. The overall device weight is controlled within 2.5 kg to ensure the convenience of daily operation. This embodiment fully considers the coordination of various components, emphasizes weather resistance and wear resistance in material selection, and stresses stability and reliability in structural design, fully meeting the requirements for use in outdoor environments.

[0043] Specifically, the principle of this utility model is as follows: Through innovative structural design and material selection, this utility model enhances the protective effect of the charging interface from multiple aspects. First, the basic structure combining a protective shell and a fixed base provides a stable installation foundation. Second, the smooth opening and closing of the protective cover is achieved through the cooperation of a swing baffle and a sliding guide rail. Third, a multi-seal structure design, including the combined application of sealing rings, sealing gaskets, and rubber sealing strips, forms a complete sealing system. Finally, the linkage mechanism design enables the swing baffle and the protective cover to open in tandem. In terms of material selection, the stress characteristics and operating environment of each component are fully considered, and materials with good wear resistance and weather resistance are selected to ensure that the device maintains good performance during long-term use. The overall design follows mechanical and ergonomic principles, providing a convenient operating experience while ensuring protective effectiveness.

[0044] In use, first securely install the base onto the charging station through the mounting holes, ensuring the protective shell aligns with the charging interface. When the charging interface is needed, the user holds the anti-slip textured area on the outer surface of the protective cover and pushes it upwards along the sliding guide rail. The movement of the protective cover drives the swing baffle to rotate around its axis to the open position. Simultaneously, a limit mechanism controls the opening angle of the swing baffle to prevent excessive rotation. After charging is complete, pull the protective cover downwards. Under the action of the drive rod, the swing baffle automatically returns to the closed position. Multiple sealing structures work together to ensure reliable protection of the charging interface. For routine maintenance, the protective shell and base can be separated by removing the bolts for easy cleaning of the internal structure or replacement of seals.
