[0026] The charging port assembly 100 according to a first aspect embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the charging port assembly 100 according to the first aspect embodiment of this utility model includes: a charging port box 1, a charging port cover 2, and a linkage mechanism 3. The charging port cover 2 has an open state (open charging port box 1) and a closed state (closed charging port box 1). The linkage mechanism 3 is connected between the charging port box 1 and the charging port cover 2 and is used to rotate the charging port cover 2 to open or close. The charging port box 1 is used to house and accommodate a charging plug that is electrically connected to the vehicle's battery. When charging is required, the charging port cover 2 can be switched to the open state so that the charging gun can be plugged into the charging plug to charge the vehicle's battery. After charging is complete and the charging gun is unplugged, the charging port cover 2 can be switched to the closed state to provide good protection for the internal space of the charging port box 1, preventing dust, rainwater, etc. from contacting the charging plug.

[0028] The connecting rod mechanism 3 comprises a first connecting rod 31, a second connecting rod 32, a third connecting rod 33 and a fourth connecting rod 34, one end of the first connecting rod 31 is rotationally connected with the charging port box 1, one end of the third connecting rod 33 is rotationally connected with the charging port cover and the first connecting rod 31 is rotationally connected with the third connecting rod 33, two ends of the second connecting rod 32 are respectively rotationally connected with the charging port box 1 and the third connecting rod 33, and two ends of the fourth connecting rod 34 are respectively rotationally connected with the charging port cover 2 and the first connecting rod 31.

[0029] That is, the connecting rod mechanism 3 can form a double four connecting rod structure with the charging port box 1 and the charging port cover 2 through the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34, that is, the part of the first connecting rod 31 connected between the charging port box 1 and the third connecting rod 33, the part of the second connecting rod 32 connected between the first connecting rod 31 and the second connecting rod 32 and the part of the charging port box 1 connected between the first connecting rod 31 and the second connecting rod 32 constitute one four connecting rod structure, and the part of the first connecting rod 31 connected between the third connecting rod 33 and the fourth connecting rod 34, the part of the third connecting rod 33 connected between the first connecting rod 31 and the charging port cover 2 and the part of the third connecting rod 33 and the charging port cover 2 connected between the third connecting rod 33 and the fourth connecting rod 34 constitute another four connecting rod structure.

[0030] It can be understood that, since the charging port cover 2 is connected with the charging port box 1 through the double four connecting rod structure, the rotation axis of the charging port cover 2 relative to the charging port box 1 is a virtual axis, in other words, the rotation axis of the charging port cover 2 relative to the charging port box 1 during switching between the open state and the closed state is not a physical axis, therefore, compared with the physical rotation axis, the connecting rod mechanism 3 saves the space occupied by the physical rotation axis, thereby effectively reducing the overall size of the charging port assembly 100, reducing the installation space occupied by the charging port assembly 100, facilitating the arrangement of parts around the charging port assembly 100. In addition, the double four connecting rod structure has simple structure but high transmission stability, thereby reducing the cost of the charging port assembly 100 and improving the stability of the charging port assembly 100.

[0031] According to the charging port assembly 100 of the first aspect of the present application, the connecting rod mechanism 3 can form a double four connecting rod structure with the charging port box 1 and the charging port cover 2 through the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34, thereby saving the space occupied by the physical rotation axis, effectively reducing the overall size of the charging port assembly 100, reducing the installation space occupied by the charging port assembly 100, and facilitating the arrangement of parts around the charging port assembly 100. In addition, the double four connecting rod structure has simple structure but high transmission stability, thereby reducing the cost of the charging port assembly 100 and improving the stability of the charging port assembly 100.

[0032] In some embodiments, the first connecting rod 31 is located between the charging port cover 2 and the second connecting rod 32, the first ends of the first connecting rod 31 and the second connecting rod 32 are rotatably connected to the charging port box 1 and are arranged at intervals, the fourth connecting rod 34 is located on the side of the third connecting rod 33 away from the first end of the first connecting rod 31, the first ends of the third connecting rod 33 and the fourth connecting rod 34 are rotatably connected to the charging port cover 2 and are arranged at intervals, the second ends of the first connecting rod 31 and the second connecting rod 32 are rotatably connected to the second end of the fourth connecting rod 34 and the second end of the third connecting rod 33 respectively, and the middle part of the first connecting rod 31 is rotatably connected to the middle part of the fourth connecting rod 34.

[0033] In one specific example, the charging port cover 2 comprises an outer panel 21 and a cover body 22 arranged on the inner side of the outer panel 21, and the outer panel 21 and the cover body 22 are connected by clamping connection, so that the connection structure between the outer panel 21 and the cover body 22 can be simplified, the assembly and disassembly difficulty of the outer panel 21 and the cover body 22 is reduced, and the assembly efficiency of the charging port cover 2 is improved and the difficulty of later maintenance or replacement is reduced.

[0034] According to some embodiments of the present application, the rotation axes of the first connecting rod 31 and the second connecting rod 32 relative to the charging port box 1 are the first axis 13 and the second axis 14 respectively, the straight line perpendicular to the first axis 13 and intersecting the first axis 13 and the second axis 14 is the first straight line 6, the rotation axes of the third connecting rod 33 and the fourth connecting rod 34 relative to the charging port cover 2 are the third axis 23 and the fourth axis 24 respectively, the straight line perpendicular to the third axis 23 and intersecting the third axis 23 and the fourth axis 24 is the second straight line 7, and the rotation axis of the charging port cover relative to the charging port box is parallel to the first axis 13, the second axis 14, the third axis 23 and the fourth axis 24, and passes through the intersection point of the first straight line 6 and the second straight line 7. Therefore, the smooth rotation of the multiple rotation connection points of the connecting rod mechanism 3 can be better ensured, so that the connecting rod mechanism 3 can stably drive the charging port cover 2 to switch between the open state and the closed state.

[0035] According to some embodiments of the present application, the second connecting rod 32 is one or a plurality arranged along the length direction of the third connecting rod 33. That is, the second connecting rod 32 can be provided with only one, so that the structural complexity of the connecting rod mechanism 3 can be better simplified, and the cost is also lower; the second connecting rod 32 can also be provided with a plurality arranged along the length direction of the third connecting rod 33, so that the stability of the expansion or folding of the connecting rod mechanism 3 can be improved through the plurality of second connecting rods 32. Therefore, the number of the second connecting rod 32 can be flexibly adjusted according to the use requirement, which is not specifically limited here.

[0036] According to some embodiments of the present utility model, the fourth connecting rod is one or multiple arranged along the length direction of the first connecting rod 31. That is, the fourth connecting rod 34 can be provided with only one, so that the structure complexity of the connecting rod mechanism 3 can be better simplified, and the cost is also lower. The fourth connecting rod 34 can also be provided with multiple arranged along the length direction of the first connecting rod 31, so that the stability of the connecting rod mechanism 3 unfolding or folding can be improved through the multiple fourth connecting rods 34. Therefore, the number of the fourth connecting rod 34 can be flexibly adjusted according to the use requirement, which is not specifically limited here.

[0037] According to some embodiments of the present utility model, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 together form a double parallelogram four connecting rod structure with the charging port box 1 and the charging port cover 2. That is, the first connecting rod 31 and the second connecting rod 32 are arranged in parallel and spaced apart with the second straight line 7, the third connecting rod 33 and the fourth connecting rod 34 are arranged in parallel and spaced apart with the first straight line 6, the first axis 13 and the second axis 14 are arranged in parallel and spaced apart, the first straight line 6 is perpendicular to the first axis 13 and the second axis 14 at the same time, the third axis 23 and the fourth axis 24 are arranged in parallel and spaced apart, and the second straight line 7 is perpendicular to the third axis 23 and the fourth axis 24 at the same time.

[0038] Specifically, the part of the first connecting rod 31 connected between the charging port box 1 and the third connecting rod 33, the part of the second connecting rod 32 connected between the first connecting rod 31 and the third connecting rod 33, and the part of the charging port box 1 connected between the first connecting rod 31 and the second connecting rod 32 constitute one parallelogram four connecting rod structure, and the part of the first connecting rod 31 connected between the third connecting rod 33 and the fourth connecting rod 34, the part of the third connecting rod 33 connected between the first connecting rod 31 and the charging port cover 2, and the part of the third connecting rod 33 and the charging port cover 2 connected between the third connecting rod 33 and the fourth connecting rod 34 constitute another parallelogram four connecting rod structure. Therefore, by forming a double parallelogram four connecting rod structure with the charging port box 1 and the charging port cover 2, the difficulty of controlling the movement trajectory of the charging port cover 2 relative to the charging port box 1 can be reduced, so as to more accurately control the movement trajectory of the charging port cover 2 relative to the charging port box 1, and the design difficulty of the connecting rod mechanism 3 is reduced.

[0039] In addition, as Figure 2As shown, the straight line perpendicular to the first straight line 6 and the second straight line 7 and passing through the intersection point P of the first straight line 6 and the second straight line 7 is the axis of rotation of the charging port cover 2 relative to the charging port box 1. Wherein, since the intersection point P does not exist in the entity structure, it is not limited by the structure, therefore, the position of the intersection point P can be adjusted by adjusting the connection positions of the first connecting rod 31 and the second connecting rod 32 with the charging port box 1 and the connection positions of the third connecting rod 33 and the fourth connecting rod 34 with the charging port cover 2, such as when the charging port cover 2 is switched from the closed state to the open state and is rotated outward and forward to open, the intersection point P can be set on the front side and the outer side of the charging port cover 2, and the distance of the intersection point P to the charging port cover 2 can be reduced, that is, the distance between the rotation axis of the charging port cover 2 relative to the charging port box 1 and the charging port cover 2 is reduced.

[0040] In one specific example, the length of the second connecting rod 32 is less than the length of the first connecting rod 31, and the length of the fourth connecting rod 34 is less than the length of the third connecting rod 33, when the charging port cover 2 is in the closed state, the first connecting rod 31 and the second connecting rod 32 are substantially perpendicular to the axial direction of the accommodation cavity 11, in the direction of the second connecting rod 32 towards the charging port cover 2, the third connecting rod 33 and the fourth connecting rod 34 extend obliquely towards the direction close to the first end of the first connecting rod 31. When the charging port cover 2 is in the open state, the first connecting rod 31 and the second connecting rod 32 are substantially perpendicular to the position parallel to the axial direction of the accommodation cavity 11, in the direction of the second connecting rod 32 towards the charging port cover 2, the third connecting rod 33 and the fourth connecting rod 34 extend obliquely towards the direction away from the first end of the first connecting rod 31. Wherein, here the axial direction of the accommodation cavity 11 refers to the direction of the charging plug.

[0041] According to some embodiments of the present application, the connection positions of the first connecting rod 31 and the third connecting rod 33, the charging port box 1 and the fourth connecting rod 34 are respectively the first hinge position 35, the second hinge position 36 and the third hinge position 37, in the length direction of the first connecting rod 31, the distance between the first hinge position 35 and the second hinge position 36 is greater than the distance between the first hinge position 35 and the third hinge position 37. Wherein, it can be understood that on the basis of keeping the length of the first connecting rod 31 unchanged, the greater the distance between the first hinge position 35 and the second hinge position 36, the greater the distance between the charging port cover 2 and the charging port box 1 in the axial direction of the accommodation cavity 11 when the charging port cover 2 is switched to the open state. Therefore, the distance between the charging port cover 2 and the charging port box 1 in the axial direction of the accommodation cavity 11 in the open state can be increased, thereby preventing the charging port cover 2 from contacting the metal structure around the charging port box 1 on the basis of controlling the overall length of the first connecting rod 31, to improve the reliability of the charging port cover 2 switching between the open state and the closed state.

[0042] According to some embodiments of the utility model, the connecting positions of third connecting rod 33 and first connecting rod 31, charging port cover 2 and second connecting rod 32 are first hinged position 35, fourth hinged position 38 and fifth hinged position 39 respectively, and the distance between first hinged position 35 and fourth hinged position 38 is greater than the distance between first hinged position 35 and fifth hinged position 39 in the length direction of third connecting rod 33. Among them, it can be understood that the greater the distance between first hinged position 35 and fourth hinged position 38, the greater the interval between charging port cover 2 and charging plug located in accommodating cavity 11 in the radial direction of accommodating cavity 11 when the charging port is switched to the open state. Therefore, by increasing the distance between first hinged position 35 and fourth hinged position 38, the distance between charging port cover 2 and charging plug in the radial direction of accommodating cavity 11 in the open state can be increased, so that charging port cover 2 can be prevented from shielding charging plug on the front side of charging plug, and charging gun and charging plug can be conveniently plugged and connected.

[0043] According to some embodiments of the utility model, a limiting portion 12 is formed on charging port box 1, limiting portion 12 is located on the side of first connecting rod 31 away from second connecting rod 32, and limiting portion 12 abuts against first connecting rod 31 in the open state. Therefore, the limiting position of charging port cover 2 when moving towards the open state can be better limited by limiting portion 12, so that the over-movement of charging port cover 2 and the contact with other surrounding parts can be avoided.

[0044] According to some embodiments of the utility model, charging port box 1 is formed with an accommodating cavity 11 for accommodating charging plug, and connecting rod mechanism 3 is accommodated in accommodating cavity 11 in the closed state. That is, when charging port cover 2 closes charging port box 1, connecting rod mechanism 3 and charging plug can share accommodating cavity 11. Therefore, connecting rod mechanism 3 can make full use of the space in accommodating cavity 11 for installing charging plug to be accommodated, and the accommodation space separately arranged for multi-connecting rod is saved, so that the space occupied by connecting rod mechanism 3 can be reduced to reduce the overall size of charging port assembly 100.

[0045] According to some embodiments of the utility model, in the open state, charging port cover 2 is located on the outer peripheral side of charging port box 1. That is, when charging port cover 2 is in the open state, it is arranged along the radial direction of accommodating cavity 11 with charging port box 1, so that the charging plug in charging port box 1 can be prevented from being shielded by charging port cover 2, and the plug-in connection of charging gun and charging plug can be facilitated.

[0046] According to some embodiments of the present application, the charging port assembly 100 further comprises a driving motor 4, which is configured to drive the first connecting rod 31 or the second connecting rod 32 to rotate relative to the charging port box 1. Therefore, the driving motor 4 can drive the first connecting rod 31 and the second connecting rod 32 to rotate forward or reverse, and drive the connecting rod mechanism 3 to move to switch the charging port cover 2 between the open state and the closed state, which can improve the intelligent level of switching the charging port cover 2 between the open state and the closed state.

[0047] In one specific example, the charging port assembly 100 further comprises a switch button 5 electrically connected to the driving motor 4, so that the user can control the switch button 5 to switch the charging port cover 2 between the open state and the closed state.

[0048] According to some embodiments of the present application, the output shaft of the driving motor 4 is connected to the first end of the first connecting rod 31. That is, the first connecting rod 31 is a driving rod, and the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are all follow-up rods, and the driving motor 4 drives the connecting rod mechanism 3 through the first connecting rod 31. Compared with the second connecting rod 32, the first connecting rod 31 is longer and closer to the charging port cover 2. Therefore, driving the first connecting rod 31 through the driving motor 4 to drive the connecting rod mechanism 3 to move can reduce the power consumption of the driving motor 4, and at the same time can improve the stability of the connecting rod mechanism 3.

[0049] Specifically, when the charging port cover 2 is switched from the closed state to the open state, the output shaft of the driving motor 4 rotates forward, driving the first connecting rod 31 to rotate counterclockwise around the hinge position of the first connecting rod 31 and the charging port box 1, and synchronously driving the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 to follow, until the charging port cover 2 is in the open state; when the charging port cover 2 is switched from the open state to the closed state, the output of the driving motor 4 is reversed, driving the first connecting rod 31 to rotate clockwise around the hinge position of the first connecting rod 31 and the charging port box 1, and synchronously driving the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 to follow, until the charging port cover 2 is in the closed state.

[0050] The vehicle according to the second aspect of the present application will be described below with reference to the accompanying drawings.

[0051] The vehicle according to the second aspect of the present application comprises a charging port assembly 100.

[0052] According to the second aspect of the utility model, the vehicle, the connecting rod mechanism 3 can form a double four connecting rod structure with the charging port box 1 and the charging port cover 2 through the first connecting rod 31, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34, the space occupied by the physical rotating shaft is saved, thereby effectively reducing the overall size of the charging port assembly 100, reducing the installation space occupied by the charging port assembly 100, facilitating the arrangement of parts around the charging port assembly 100. In addition, the double four connecting rod structure is simple in structure but high in transmission stability, thereby reducing the cost of the charging port assembly 100 and improving the stability of the charging port assembly 100.
