[0032] Reference is made below to Figures 1-5 describe the charging port cover 100 according to an embodiment of the present utility model.

[0033] As Figure 4 and Figure 5 shown, the charging port cover 100 according to an embodiment of the present utility model includes a cover plate 1 and a hinge 2.

[0034] Specifically, as Figure 1 and Figure 2 shown, the hinge 2 includes a rotating part 21 and a connecting part 22. One end of the rotating part 21 is adapted to be connected to the vehicle body, and the other end is connected to the connecting part 22. Preferably, the rotating part 21 and the vehicle body are rotatably connected by a shaft-hole fit. The other end of the rotating part 21 and the connecting part 22 may be a detachable connection connected by a fastener such as a screw, or may be an integrally formed fixed connection. Thus, the rotating part 21 can drive the connecting part 22 to rotate together around the rotation axis at the connection between the connecting part 22 and the vehicle body. The connecting part 22 is detachably connected to the cover plate 1. The cover plate 1 is used to cover the charging port of the vehicle body, and can open or close the charging port of the vehicle body through the hinge 2, protecting the charging socket of the vehicle body and playing a role in decoration and beauty at the same time. The connecting part 22 and the cover plate 1 can be connected by snap connection, which is convenient for assembly and also convenient for disassembly and maintenance.

[0035] Among them, a first mating portion 11 is provided on the surface of the cover plate 1 facing the connecting portion 22, and a second mating portion 3 that mates with the first mating portion 11 is provided on the surface of the connecting portion 22 facing the cover plate 1, which is used to limit the movement of the cover plate 1 in the direction away from the rotating portion 21, playing a role in fixing and positioning the cover plate 1. For example, the first mating portion 11 of the cover plate 1 and the second mating portion 3 of the connecting portion 22 can be convex structures. The second mating portion 3 of the connecting portion 22 has an end face on the side close to the rotating portion 21 that can be fitted with the end face of the first mating portion 11 away from the rotating portion 21. When the end face of the first mating portion 11 away from the rotating portion 21 abuts against the end face of the second mating portion 3 close to the rotating portion 21, the cover plate 1 cannot move in the direction away from the rotating portion 21, playing a role in fixing and positioning the cover plate 1. In addition, the cover plate 1 and the connecting portion 22 have other snap-fit structures that can correspond and cooperate with each other, which are used to limit the movement of the cover plate 1 relative to the connecting portion 22 in other directions except away from the rotating portion 21. The detachable connection between the connecting portion 22 and the cover plate 1 can be realized by the cooperation of the first mating portion 11 and the second mating portion 3 and other snap-fit structures, and the assembly is simple and convenient for disassembly and maintenance.

[0036] Furthermore, as Figure 5 shown, the position on the surface of the connecting portion 22 facing away from the cover plate 1 and opposite to the second mating portion 3 is a complete and hole-free surface, which can effectively avoid the occurrence of water seepage and leakage at the connection, helping to ensure the function and reliability of the charging port cover 100 and increasing the safety of the charging port of the vehicle body. On the other hand, the complete and hole-free surface also improves the appearance delicacy and aesthetics.

[0037] According to the charging port cover 100 of the embodiment of the present invention, by respectively providing a first mating portion 11 and a second mating portion 3 that can cooperate with each other on the surfaces of the cover plate 1 and the connecting portion 22, the movement of the cover plate 1 in the direction away from the rotating portion 21 can be limited, which helps to realize the detachable connection between the connecting portion 22 and the cover plate 1, and the assembly is simple and convenient for disassembly and maintenance. The position on the surface of the connecting portion 22 facing away from the cover plate 1 and opposite to the second mating portion 3 is a complete and hole-free surface, whereby the situation of water leakage at the connecting portion 22 can be effectively avoided, which helps to ensure the function and reliability of the charging port cover 100, increases the safety of the charging port of the vehicle body, and at the same time improves the appearance delicacy and aesthetics.

[0038] In some embodiments of the present invention, as Figure 2 and Figure 3As shown in the figure, the second engaging portion 3 includes an elastic arm 31. One end of the elastic arm 31 is connected to the surface of the connecting portion 22 facing the cover plate 1, and the other end extends toward the rotating portion 21 and is spaced apart from the surface of the connecting portion 22 facing the cover plate 1. Thus, the elastic arm 31 can provide a certain elasticity. When a force is applied to one end of the elastic arm 31 near the rotating portion 21, it can move in a direction closer to or away from the surface of the connecting portion 22. The first engaging portion 11 is adapted to abut against the end face of the elastic arm 31 facing the rotating portion 21, which can ensure the stable cooperation between the cover plate 1 and the connecting portion 22. On the one hand, it can limit the movement of the cover plate 1 in the direction away from the rotating portion 21, playing a role in fixing and positioning the cover plate 1. On the other hand, it can achieve detachable connection. For example, the first engaging portion 11 of the cover plate 1 can be a convex structure, and the end face of the first engaging portion 11 away from the rotating portion 21 can be attached to and abut against the end face of the elastic arm 31 facing the rotating portion 21. At this time, the cover plate 1 cannot move in the direction away from the rotating portion 21, playing a role in fixing and positioning the cover plate 1. When a force is applied to one end of the elastic arm 31 near the rotating portion 21 in the direction closer to the surface of the connecting portion 22, the elastic arm 31 deforms, and one end of the elastic arm 31 near the rotating portion 21 moves in the direction closer to the surface of the connecting portion 22. When the force reaches a certain degree, the portion of the elastic arm 31 abutting against the first engaging portion 11 disengages, thereby realizing the disassembly of the first engaging portion 11 and the second engaging portion 3.

[0039] Preferably, the width of the portion where the first engaging portion 11 abuts against the end face of the elastic arm 31 facing the rotating portion 21 can be set to about 1.5 millimeters. If the abutting area is too large, it is not conducive to disassembly; if the abutting area is too small, the stability of the cooperation between the first engaging portion 11 and the elastic arm 31 cannot be guaranteed. The width of the portion where the first engaging portion 11 abuts against the elastic arm 31 is moderate, which can not only ensure the stable cooperation between the first engaging portion 11 and the elastic arm 31 but also facilitate disassembly.

[0040] In some embodiments of the present utility model, as Figure 3 shown, an operating portion 32 is provided on the elastic arm 31. The operating portion 32 faces the cover plate 1, which can intuitively indicate the force application area of the elastic arm 31, facilitating the user to disassemble the cover plate 1 through the operating portion 32. The setting of the operating portion 32 can improve the user's convenience and operability.

[0041] In some embodiments of the present utility model, as Figure 3 shown, the operating portion 32 is a rib or a groove provided on the elastic arm 31. The user can apply a force to the elastic arm 31 by using a tool to abut against the rib on the elastic arm 31 or inserting the tool into the groove on the elastic arm 31, which is convenient for the user to apply force and operate, facilitating assembly and disassembly, and improving the user's sense of use.

[0042] In some embodiments of the present utility model, as Figure 3 shown, the operation part 32 is arranged at the free end of the elastic arm 31. When a user applies a force to the operation part 32, it is more convenient for the free end of the elastic arm 31, which is the end close to the rotation part 21, to move towards the direction close to the surface of the connection part 22. When the user disassembles the cover plate 1, there is no need to apply too much force, which saves effort for the user, makes disassembly more convenient and improves the user's convenience of use.

[0043] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, the elastic arm 31 includes a main body part 311 and a convex part 312. One end of the main body part 311 is connected to the surface of the connection part 22 facing the cover plate 1, and the other end extends towards the rotation part 21 and is spaced apart from the surface of the connection part 22 facing the cover plate 1. Thus, the main body part 311 has a certain elasticity. When a force is applied to the end of the main body part 311 close to the rotation part 21, it can move towards the direction close to or away from the surface of the connection part 22. Further, the convex part 312 is arranged at the free end of the main body part 311 and is located on the surface of the main body part 311 facing the cover plate 1, and is used to abut against the first matching part 11. On the one hand, it can increase the area where the elastic arm 31 abuts against the first matching part 11, ensure the stable cooperation between the cover plate 1 and the connection part 22, and further ensure the function of the elastic arm 31 in fixing and limiting the cover plate 1. On the other hand, the convex part 312 of the elastic arm 31 effectively increases the distance and space between the cover plate 1 and the main body part 311, which can provide enough operating space for the user to disassemble the cover plate 1 and is convenient for operation. At the same time, the user can also use a tool to abut against the root of the convex part 312 to apply a force, which improves the convenience of use. At the same time, the user can also use a tool to abut against the root of the convex part 312 to apply a force, which improves the convenience of use.

[0044] In some embodiments of the present utility model, as Figure 2 and Figure 3 shown, the surface of the convex part 312 facing the rotation part 21 is flush with the surface of the main body part 311 facing the rotation part 21, which can ensure the flatness and consistency of the surface of the elastic arm 31 facing the rotation part 21 and is convenient for abutting against the first matching part 11. On the one hand, it can ensure the stable cooperation between the first matching part 11 and the elastic arm 31 and ensure the function of the elastic arm 31 in fixing and limiting the cover plate 1. On the other hand, when a force is applied to the end of the elastic arm 31 close to the rotation part 21, the free end of the elastic arm 31 moves towards the direction close to the surface of the connection part 22. The flat surface of the elastic arm 31 facing the rotation part 21 is beneficial to the separation of the elastic arm 31 from the first matching part 11, making disassembly more labor-saving and convenient.

[0045] In some embodiments of the present utility model, as Figure 2 and Figure 3As shown, the surface of the protrusion 312 facing away from the rotating part 21 is inclined towards the cover plate 1 in the direction facing the rotating part 21, so that the first engaging part 11 can slide from the main body part 311 through the inclined surface of the protrusion 312 to the side of the protrusion 312 close to the rotating part 21 under the action of an external force, facilitating the connection and assembly of the cover plate 1 and the hinge 2. For example, when assembling the cover plate 1 and the hinge 2, a force towards the connecting part 22 of the hinge 2 is applied to the cover plate 1, and at the same time, the cover plate 1 is pushed towards the rotating part 21 of the hinge 2. The first engaging part 11 of the cover plate 1 will abut against the main body part 311 of the elastic arm 31, causing the free end of the elastic arm 31 to move in the direction towards the surface close to the connecting part 22. At this time, under the action of the force towards the rotating part 21, the first engaging part 11 of the cover plate 1 will slide from the main body part 311 of the elastic arm 31 to the protrusion 312 and slide to the side of the protrusion 312 close to the rotating part 21 through the inclined surface of the protrusion 312. The first engaging part 11 abuts against the surface of the protrusion 312 facing the rotating part 21, thereby restricting the cover plate 1 from moving away from the rotating part 21, realizing the connection and assembly of the connecting part 22 and the cover plate 1.

[0046] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the second engaging part 3 and the connecting part 22 are an integral part. The second engaging part 3 can be integrally injection-molded with the connecting part 22, reducing the production cost while also simplifying the manufacturing and assembly process of the charging port cover 100.

[0047] The vehicle according to an embodiment of the present utility model will be described below.

[0048] The vehicle according to an embodiment of the present utility model includes the above-mentioned charging port cover 100.

[0049] Specifically, as Figure 1 and Figure 2 shown, the charging port cover 100 of the vehicle includes a cover plate 1 and a hinge 2. The hinge 2 includes a rotating part 21 and a connecting part 22. One end of the rotating part 21 is adapted to be connected to the vehicle body. Preferably, the rotating part 21 is rotatably connected to the vehicle body by a shaft-hole fit. The other end of the rotating part 21 is connected to the connecting part 22. Thus, the rotating part 21 can drive the connecting part 22 to rotate together around the rotation axis at the connection between the connecting part 22 and the vehicle body. The connecting part 22 is detachably connected to the cover plate 1, facilitating assembly and also convenient for disassembly and maintenance. The cover plate 1 is used to cover the charging port of the vehicle body, can open or close the charging port of the vehicle body through the hinge 2, protects the charging socket of the vehicle body while playing a role in decoration and beauty, and at the same time provides a more convenient charging experience for users.

[0050] Among them, a first fitting portion 11 is provided on the surface of the cover plate 1 facing the connecting portion 22, and a second fitting portion 3 that cooperates with the first fitting portion 11 is provided on the surface of the connecting portion 22 facing the cover plate 1, which is used to limit the movement of the cover plate 1 in the direction away from the rotating portion 21 and plays a role in fixing and positioning the cover plate 1. For example, the first fitting portion 11 of the cover plate 1 and the second fitting portion 3 of the connecting portion 22 can be convex structures. The second fitting portion 3 of the connecting portion 22 has an end face on the side close to the rotating portion 21 that can be fitted with the end face of the first fitting portion 11 away from the rotating portion 21. When the end face of the first fitting portion 11 away from the rotating portion 21 abuts against the end face of the second fitting portion 3 close to the rotating portion 21, the cover plate 1 cannot move in the direction away from the rotating portion 21, thus playing a role in fixing and positioning the cover plate 1. In addition, the cover plate 1 and the connecting portion 22 have other snap-fit structures that can cooperate with each other to limit the movement of the cover plate 1 relative to the connecting portion 22 in other directions except away from the rotating portion 21. The detachable connection between the connecting portion 22 and the cover plate 1 can be realized by the cooperation of the first fitting portion 11 and the second fitting portion 3 with other snap-fit structures, which is simple in assembly and convenient for disassembly and maintenance, thereby reducing the assembly and maintenance costs of the vehicle.

[0051] Furthermore, as Figure 5 shown, the position on the surface of the connecting portion 22 facing away from the cover plate 1 and opposite to the second fitting portion 3 is a complete and hole-free surface, which can effectively prevent water seepage and leakage from occurring in the connecting portion 22 of the hinge 2, helps to ensure the function and reliability of the charging port cover 100 of the vehicle, and increases the safety of the charging port of the vehicle. On the other hand, the complete and hole-free surface also improves the appearance delicacy and beauty.

[0052] For the vehicle according to the embodiment of the present invention, by respectively providing a first fitting portion 11 and a second fitting portion 3 that can cooperate with each other on the surfaces of the cover plate 1 and the connecting portion 22 of the charging port cover 100, the movement of the cover plate 1 in the direction away from the rotating portion 21 can be limited, which helps to realize the detachable connection between the connecting portion 22 and the cover plate 1, is simple in assembly and convenient for disassembly and maintenance, thereby reducing the assembly and maintenance costs of the vehicle. The position on the surface of the connecting portion 22 facing away from the cover plate 1 and opposite to the second fitting portion 3 is a complete and hole-free surface, whereby water seepage and leakage in the connecting portion 22 of the hinge 2 can be effectively prevented, which helps to ensure the function and reliability of the charging port cover 100 of the vehicle, and increases the safety of the charging port of the vehicle while also improving the appearance delicacy and beauty.
