Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1 to 8This utility model provides a technical solution: a charging port structure for an electric vehicle, including an electric vehicle frame 101. A charging port body 102 is provided on the end side of the electric vehicle frame 101. The charging port body 102 is electrically connected to a lithium battery installed inside the electric vehicle frame 101 via wires. An mounting ring 105 is installed on the outer surface of the charging port body 102 through an annular groove. A spring sheet 103 is integrally provided on one side of the mounting ring 105. A sealing protective cover 104 is provided at the end of the spring sheet 103. A magnetic ring 108 is glued and fixed to the bottom of the inner side of the sealing protective cover 104 with strong adhesive. The inner side of the charging port body 102... A magnetic ring 106 is glued to the bottom and the edge of the upper surface with strong adhesive. Limiting grooves 107 are formed on both sides of the charging port body 102. When the charging port body 102 is used after charging, the spring sheet 103 and the reinforcing elastic sheet 1031 will cause the sealing cover 104 to automatically close on the surface of the charging port body 102. After closing, the magnetic ring 108 and the magnetic ring 106 will be attracted and fixed, which facilitates sealing and dust and water protection. After the charger plug is inserted into the charging port body 102, the magnetic ring 108 and the magnetic ring 106 at the bottom of the charging port body 102 are vertically inserted for charging.

[0027] An anti-collision protection mechanism is provided at the edge of the charging port body 102 on the upper surface of the electric vehicle frame 101. The anti-collision protection mechanism includes an anti-collision protection component provided at the edge of the charging port body 102. A rotating mounting component is provided on the inner surface of the anti-collision protection component, and a fixing component is provided at the bottom of the inner part of the anti-collision protection component. After the charging port body 102 is installed, the anti-collision protection mechanism will protect the edge of the charging port body 102 from collision, making it less likely to be damaged.

[0028] In order to facilitate the installation of anti-collision protection at the edge of the charging port body 102 using the anti-collision protection component, in this embodiment, preferably, the anti-collision protection component includes an anti-collision mounting iron ring 1021 located on the upper surface of the electric vehicle frame 101 at the edge of the charging port body 102. The outer surface of the anti-collision mounting iron ring 1021 is glued and fixed with a buffer rubber ring 1022. The anti-collision mounting iron ring 1021 can be installed at the edge of the charging port body 102 for anti-collision protection, and buffered by the buffer rubber ring 1022.

[0029] To facilitate the closed installation of the anti-collision mounting ring 1021 via a rotating mounting assembly, in this embodiment, preferably, the rotating mounting assembly includes an internally threaded ring 1024 integrally disposed at the edge of the inner surface of the anti-collision mounting ring 1021, and an externally threaded structure 1023 formed at the bottom edge of the charging port body 102. The externally threaded structure 1023 matches the internally threaded structure of the internally threaded ring 1024, and the anti-collision mounting ring 1021 can be installed by rotating the externally threaded structure 1023 and the internally threaded ring 1024, thus facilitating the installation and use of the anti-collision mounting ring 1021.

[0030] In order to facilitate the screw to be inserted and fixed by the fixing component, in this embodiment, preferably, the fixing component includes a mounting hole 1025 opened at the bottom edge of the inner side of the anti-collision mounting ring 1021, and the mounting hole 1025 and the inner bottom side of the anti-collision mounting ring 1021 are integral structures. After the anti-collision mounting ring 1021 is rotated and installed, the screw can be inserted into the electric vehicle frame 101 through the mounting hole 1025 for reinforcement.

[0031] The inner surface of the bottom end of the spring sheet 103 is provided with a reinforcing elastic mechanism. The reinforcing elastic mechanism includes a reinforcing elastic component provided on the inner bottom end surface of the spring sheet 103. The surface of the reinforcing elastic component is provided with a snap-fit ​​mounting component. During installation and use, the reinforcing elastic mechanism can automatically and elastically close the spring sheet 103 to effectively seal and prevent dust and water.

[0032] In order to enhance the elasticity of the spring sheet 103 by strengthening the elastic component, and to prevent frequent bending from weakening the elasticity and to ensure effective elastic closure, in this embodiment, preferably, the strengthening elastic component includes a strengthening elastic sheet 1031 disposed at the bottom end of the inner surface of the spring sheet 103. One end surface of the strengthening elastic sheet 1031 contacts the bottom end surface of the charging port body 102. When the strengthening elastic sheet 1031 is installed on the bottom end of the inner surface of the spring sheet 103 and the surface of the charging port body 102, the strengthening elastic sheet 1031 strengthens the elasticity of the spring sheet 103, and always effectively presses and closes for protection.

[0033] To facilitate the installation of the reinforcing elastic sheet 1031 using the snap-fit ​​mounting assembly, in this embodiment, preferably, the snap-fit ​​mounting assembly includes snap-fit ​​balls 1032 integrally disposed at both ends of the outer surface of the reinforcing elastic sheet 1031. The bottom end of the inner surface of the spring sheet 103 and the bottom end of the outer surface of the charging port body 102 are both provided with snap-fit ​​holes 1033 that engage with the snap-fit ​​balls 1032. The end of the reinforcing elastic sheet 1031 can be installed and used with the surface of the spring sheet 103 and the charging port body 102 by snapping the snap-fit ​​balls 1032 into the snap-fit ​​holes 1033.

[0034] The working principle and usage process of this utility model are as follows: When using this type of electric vehicle charging port structure, the charging port body 102 is first installed on the corresponding position on the electric vehicle frame 101. After fixed installation, the anti-collision mounting iron ring 1021 is installed on the outer surface edge of the charging port body 102 through the threaded connection between the external thread structure 1023 and the internal thread ring 1024. Then, the screw is inserted into the corresponding internal thread hole inside the electric vehicle frame 101 through the mounting hole 1025 for fixed installation. Therefore, when the charging port body 102 is installed on the electric vehicle frame 101, when the outer surface of the charging port body 102 is impacted, it directly impacts the surface of the buffer rubber ring 1022 and the anti-collision mounting iron ring 1021. The buffer rubber ring 1022 is deformed to buffer the impact, and the anti-collision mounting iron ring 1021 is used for anti-collision protection. It is not easy to damage the charging port body 102 during impact, ensuring safe installation and use, and improving the convenience of anti-collision protection for the charging port body 102 installed on the electric vehicle frame 101.

[0035] Before use, after the mounting ring 105 is engaged with the outer surface of the charging port body 102, the spring sheet 103 and the sealing cover 104 are again engaged with the reinforcing elastic sheet 1031 by the retaining ball 1032. The two ends of the reinforcing elastic sheet 1031 are respectively engaged with the inner surface of the spring sheet 103 and the outer surface of the charging port body 102, which facilitates the installation of the reinforcing elastic sheet 1031. Therefore, after the charging port body 102 is charged, the spring sheet 103 and the reinforcing elastic sheet 1031 elastically drive the sealing cover 104 to automatically close on the surface of the charging port body 102, and after closing, the second magnet ring 108 and the first magnet ring 106 are attracted. The device is fixed, convenient for sealing and closing, and is dustproof and waterproof. When the elasticity of the spring sheet 103 weakens due to frequent opening and closing, the elasticity is strengthened by the reinforcing elastic sheet 1031, which can still assist in automatic closing and installation. This improves the convenience of closing the charging port body 102 and the spring sheet 103 after installation on the electric vehicle frame 101. During charging, a corresponding magnetic ring 2 108 can be installed at the end edge of the external charger plug, so that after the charger plug is inserted into the inside of the charging port body 102, the magnetic ring 2 108 and the magnetic ring 106 at the bottom inside the charging port body 102 are vertically inserted for charging.
