[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 4 The utility model provides a protective device for an electric vehicle charging port, comprising a charging cover 1, a cover plate 2 is opened and closed on the charging cover 1, a protective cover 3 is fixedly connected to the inner wall of the charging cover 1 away from the cover plate 2, the protective cover 3 is arranged outside the charging port, and a plug 4 is clamped on the inner wall of the protective cover 3 close to the cover plate 2;

[0024] A plurality of protective covers 5 are arranged on the inner wall of the charging housing 1 away from the cover plate 2, and two adjacent protective covers 5 are slidably connected. One end of the innermost protective cover 5 away from the cover plate 2 is fixedly connected to the inner wall of the charging housing 1, and the innermost protective cover 5 is wound around the outside of the protective cover 3.

[0025] The charging cover 1 is fixedly embedded in the body of the electric vehicle, and the cover 2 is connected to the body of the electric vehicle (the cover 2 is rotatably connected to the body, and a locking structure is provided between the cover 2 and the body, which is a prior art and will not be described in detail here). When not charging, the cover 2 is closed to cover the charging cover 1. When charging is required, the cover 2 is opened and the plug 4 is removed to expose the charging port for charging;

[0026] In this embodiment, the protective cover 3 and the plug 4 are both made of rubber material, and there is an interference fit between the two, thereby achieving a tight connection and improving the sealing of the connection;

[0027] When not charging, the cover plate 2 covers the charging cover 1, and the plug 4 is inserted into the protective cover 3, thereby forming a double protection for the charging port, improving the protection effect of the charging port; and when the plug 4 is damaged, it can be replaced at any time, which is convenient and easy to use; when charging, the charging gun is connected to the charging port, and the multi-layer protective cover 5 is stretched out in sequence, so that the protective cover 5 is set outside the charging gun, and the connection between the charging port and the charging gun is protected, reducing the impact of rainwater on charging and improving charging safety. The utility model can effectively protect the charging port by setting the protective cover 3, the plug 4 and the multi-layer protective cover 5, reducing the impact of external sand, dust and rainwater on the charging port.

[0028] Further optimized solution, multiple flexible connecting belts 6 are fixedly connected to the outer wall of the outermost protective cover 5, and the other end of the flexible connecting belt 6 is detachably connected to the inner wall of the innermost protective cover 5. When the flexible connecting belt 6 is connected to the inner wall of the innermost protective cover 5, the end surfaces of the multiple protective covers 5 close to the cover plate 2 are flush;

[0029] A plurality of first magnetic plates 7 are fixedly connected to the inner wall of the innermost protective cover 5, and a second magnetic plate 8 is fixedly connected to one end of the flexible connecting belt 6 away from the outermost protective cover 5, and the first magnetic plates 7 and the second magnetic plates 8 are magnetically connected;

[0030] An inclination angle is set between the protective cover 5 and the ground, and the end of the protective cover 5 away from the inner wall of the charging cover shell 1 is inclined toward the ground; the protective cover 5 is made of rubber, and the size of the protective cover 5 is larger than the size of the charging gun, so that the cover is conveniently arranged outside the charging gun, and the protective cover 5 is inclined toward the ground, so that rainwater can drip onto the ground along the protective cover 5;

[0031] When not charging, the flexible connecting belt 6 bypasses the middle layer of the protective cover 5, so that the first magnetic plate 7 is magnetically connected to the second magnetic plate 8, thereby limiting the storage of multiple protective covers 5 to facilitate the closing of the cover 2; when charging, if there is an invasion of rain, the second magnetic plate 8 is removed from the first magnetic plate 7, and then the multiple protective covers 5 are released one by one, so that their covers are located outside the charging gun, preventing rainwater from directly contacting the connection between the charging gun and the charging port, thereby improving charging safety.

[0032] According to a further optimization scheme, a plurality of slide grooves 9 are provided on the outer wall of the protective cover 5 , a plurality of sliders 10 are fixedly connected to the inner wall of the protective cover 5 , and the sliders 10 on the protective cover 5 are slidably connected to the slide grooves 9 on the adjacent protective cover 5 .

[0033] Further optimizing the solution, one end of the plug 4 is fixedly connected to the limit plate 11, and when the plug 4 is inserted into the protective cover 3, the limit plate 11 contacts the end surface of the protective cover 3;

[0034] A handle 12 is fixedly connected to one end of the limiting plate 11 away from the plug 4;

[0035] A connecting ring 13 is fixedly connected to the handle 12 and the inner wall of the charging housing 1 away from the cover plate 2, and a connecting rope 14 is fixedly connected between the two connecting rings 13;

[0036] When charging, after the plug 4 is removed, the connecting rope 14 provided can prevent the plug 4 from being lost; the connecting rope 14 is tied to the connecting ring 13, and when the plug 4 needs to be replaced, the connecting rope 14 is directly loosened and a new plug 4 is replaced, thereby improving the convenience of use.
