The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0025] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0026] The following describes a charging port assembly 100 according to an embodiment of the first aspect of the present invention with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the charging port assembly 100 according to the first embodiment of the present invention includes: a charging port box 1, a charging port cover 2 and a connecting rod mechanism 3. The charging port cover 2 has an open state for opening the charging port box 1 and a closed state for closing the charging port box 1. The connecting rod mechanism 3 is connected between the charging port box 1 and the charging port cover 2, and is used to rotate and drive the charging port cover 2 to open or close. Among them, the charging port box 1 is used to install and accommodate a charging plug electrically connected to the battery of the vehicle. When charging is required, the charging port cover 2 can be switched to an open state so that the charging gun can be plugged into the charging plug to charge the battery of the vehicle; when charging is completed and the charging gun is unplugged, the charging port cover 2 can be switched to a closed state to provide good protection for the internal space of the charging port box 1 and prevent dust, rain, etc. from contacting the charging plug.

[0028] The connecting rod mechanism 3 includes 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 rotatably connected to the charging port box 1, one end of the third connecting rod 33 is rotatably connected to the charging port cover and the first connecting rod 31 is rotatably connected to the third connecting rod 33, both ends of the second connecting rod 32 are rotatably connected to the charging port box 1 and the third connecting rod 33 respectively, and both ends of the fourth connecting rod 34 are rotatably connected to the charging port cover 2 and the first connecting rod 31 respectively.

[0029] That is to say, the connecting rod mechanism 3 can form a double four-bar structure together 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 second connecting rod 32, the part of the third connecting rod 33 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 of the four-bar structures, and the part of the first connecting rod 33 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, the third connecting rod 33 and the part of the charging port cover 2 connected between the third connecting rod 33 and the fourth connecting rod 34 constitute another four-bar structure.

[0030] It is understandable that, since the charging port cover 2 is connected to the charging port box 1 through a double four-bar linkage 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 the 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, and facilitating the arrangement of components around the charging port assembly 100. In addition, the double four-bar linkage structure has a 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 embodiment of the present invention, the connecting rod mechanism 3 can form a double four-link 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 eliminating the space occupied by the physical rotating shaft, thereby 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 components around the charging port assembly 100. In addition, the double four-link structure has a 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 link 31 is located between the charging port cover 2 and the second link 32, the first ends of the first link 31 and the second link 32 are rotatably connected to the charging port box 1 and are spaced apart, the fourth link 34 is located on the side of the third link 33 away from the first end of the first link 31, the first ends of the third link 33 and the fourth link 34 are rotatably connected to the charging port cover 2 and are spaced apart, the second ends of the first link 31 and the second link 32 are rotatably connected to the second end of the fourth link 34 and the second end of the third link 33 respectively, and the middle part of the first link 31 is rotatably connected to the middle part of the fourth link 34.

[0033] In a specific example, the charging port cover 2 includes an outer trim panel 21 and a cover body 22 arranged on the inner side of the outer trim panel 21. The outer trim panel 21 and the cover body 22 are snap-connected, which can simplify the connection structure between the outer trim panel 21 and the cover body 22 and reduce the difficulty of assembling and disassembling the outer trim panel 21 and the cover body 22, which is beneficial to improving the assembly efficiency of the charging port cover 2 and reducing the difficulty of later maintenance or replacement.

[0034] According to some embodiments of the present invention, 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, and 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, and 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. 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 of the first straight line 6 and the second straight line 7. Thus, the smooth rotation of the multiple rotation connection points of the connecting rod mechanism 3 can be better guaranteed, 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 invention, the second connecting rod 32 is one or multiple second connecting rods 32 arranged along the length direction of the third connecting rod 33. That is, only one second connecting rod 32 can be provided, so that the structural complexity of the connecting rod mechanism 3 can be simplified well, and the cost is also low; multiple second connecting rods 32 can also be provided along the length direction of the third connecting rod 33, so that the stability of the connecting rod mechanism 3 when unfolded or folded can be improved by multiple second connecting rods 32. Therefore, the number of second connecting rods 32 can be flexibly adjusted according to the use requirements, and no specific limitation is made here.

[0036] According to some embodiments of the present invention, the fourth connecting rod is one or multiple fourth connecting rods arranged along the length direction of the first connecting rod 31. That is, only one fourth connecting rod 34 can be provided, so that the structural complexity of the connecting rod mechanism 3 can be simplified well, and the cost is also low; the fourth connecting rod 34 can also be arranged in multiple fourth connecting rods 34 arranged in the length direction of the first connecting rod 31, so that the stability of the connecting rod mechanism 3 when unfolded or folded can be improved by multiple fourth connecting rods 34. Therefore, the number of the fourth connecting rod 34 can be flexibly adjusted according to the use requirements, and no specific limitation is made here.

[0037] According to some embodiments of the present invention, the first connecting rod 31, the second connecting rod 32, the third connecting rod 33, the fourth connecting rod 34, the charging port box 1 and the charging port cover 2 form a double parallelogram four-bar structure. That is, the first connecting rod 31 is arranged parallel and spaced with the second connecting rod 32 and the second straight line 7, the third connecting rod 33 is arranged parallel and spaced with the fourth connecting rod 34 and the first straight line 6, the first axis 13 and the second axis 14 are arranged parallel and spaced, 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 parallel and spaced, 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 portion of the first link 31 connected between the charging port box 1 and the third link 33, the second link 32, the portion of the third link 33 connected between the first link 31 and the second link 32, and the portion of the charging port box 1 connected between the first link 31 and the second link 32 constitute one of the parallelogram four-bar structures, and the portion of the first link 33 connected between the third link 33 and the fourth link 34, the portion of the third link 33 connected between the first link 31 and the charging port cover 2, and the portion of the third link 33 and the charging port cover 2 connected between the third link 33 and the fourth link 34 constitute another parallelogram four-bar structure. Therefore, by forming a double parallelogram four-bar structure with the link mechanism 3, the charging port box 1, and the charging port cover 2, the difficulty of controlling the motion trajectory of the charging port cover 2 relative to the charging port box 1 can be reduced, so as to more accurately control the motion trajectory of the charging port cover 2 relative to the charging port box 1, which is conducive to reducing the design difficulty of the link mechanism 3.

[0039] In addition, if 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. Among them, since the intersection point P does not exist in the physical structure, it is not restricted by the structure. Therefore, the position of the intersection point P can be adjusted by adjusting the connection position of the first connecting rod 31 and the second connecting rod 32 with the charging port box 1 and the connection position of the third connecting rod 33 and the fourth connecting rod 34 with the charging port cover 2. For example, when the charging port cover 2 is switched from the closed state to the open state and rotated outward and forward to open, the intersection point P can be set at the front side and the outer side of the charging port cover 2, which can reduce the distance from the intersection point P to the charging port cover 2, that is, reduce 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.

[0040] In a specific example, the length of the second connecting rod 32 is less than that of the first connecting rod 31, and the length of the fourth connecting rod 34 is less than that of the third connecting rod 33. When the charging port cover 2 is in a closed state, the first connecting rod 31 and the second connecting rod 32 are approximately perpendicular to the axial direction of the accommodating cavity 11, and in the direction from the second connecting rod 32 toward the charging port cover 2, the third connecting rod 33 and the fourth connecting rod 34 extend obliquely toward the direction close to the first end of the first connecting rod 31. When the charging port cover 2 is in an open state, the first connecting rod 31 and the second connecting rod 32 are approximately perpendicular to the axial direction of the accommodating cavity 11, and in the direction from the second connecting rod 32 toward the charging port cover 2, the third connecting rod 33 and the fourth connecting rod 34 extend obliquely toward the direction away from the first end of the first connecting rod 31. The axial direction of the accommodating cavity 11 here refers to the direction of the charging plug.

[0041] According to some embodiments of the present invention, the connection positions of the first link 31 and the third link 33, the charging port box 1 and the fourth link 34 are the first hinge position 35, the second hinge position 36 and the third hinge position 37 respectively. In the length direction of the first link 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. It can be understood that, on the basis of the first link 31 remaining unchanged in length, 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 accommodating chamber 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 accommodating chamber 11 in the open state can be increased, so that the charging port cover 2 can be prevented from contacting the sheet metal structure around the charging port box 1 on the basis of controlling the overall length of the first link 31, so as 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 present invention, the connection positions of the third link 33 with the first link 31, the charging port cover 2 and the second link 32 are respectively the first hinge position 35, the fourth hinge position 38 and the fifth hinge position 39. In the length direction of the third link 33, the distance between the first hinge position 35 and the fourth hinge position 38 is greater than the distance between the first hinge position 35 and the fifth hinge position 39. It can be understood that the greater the distance between the first hinge position 35 and the fourth hinge position 38, the greater the radial distance between the charging port cover 2 and the charging plug located in the accommodating cavity 11 when the charging port is switched to the open state. Therefore, by increasing the distance between the first hinge position 35 and the fourth hinge position 38, the radial distance between the charging port cover 2 and the charging plug in the accommodating cavity 11 can be increased when the charging port is in the open state, so as to prevent the charging port cover 2 from blocking the charging plug in front of the charging plug, and facilitate the plug-in connection between the charging gun and the charging plug.

[0043] According to some embodiments of the present invention, a limiting portion 12 is formed on the charging port box 1, and the limiting portion 12 is located on the side of the first connecting rod 31 away from the second connecting rod 32. In the open state, the limiting portion 12 abuts against the first connecting rod 31. Therefore, the limiting portion 12 can better limit the limit position of the charging port cover 2 when it moves toward the open state, thereby preventing the charging port cover 2 from moving excessively and contacting other surrounding components.

[0044] According to some embodiments of the present invention, the charging port box 1 is formed with a receiving cavity 11 for receiving the charging plug, and in the closed state, the connecting rod mechanism 3 is received in the receiving cavity 11. That is, when the charging port cover 2 closes the charging port box 1, the connecting rod mechanism 3 and the charging plug can share the receiving cavity 11. As a result, the connecting rod mechanism 3 can make full use of the space in the receiving cavity 11 for installing the charging plug for storage, eliminating the storage space set separately for the multi-link storage, thereby reducing the space occupied by the connecting rod mechanism 3 to reduce the overall size of the charging port assembly 100.

[0045] According to some embodiments of the present invention, in the open state, the charging port cover 2 is located on the outer peripheral side of the charging port box 1. That is, when the charging port cover 2 is in the open state, it is arranged with the charging port box 1 along the radial direction of the accommodating cavity 11, so that the charging port cover 2 can avoid blocking the charging plug in the charging port box 1, and facilitate the plug-in connection between the charging gun and the charging plug.

[0046] According to some embodiments of the present invention, the charging port assembly 100 further includes: a driving motor 4, which is used 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, drive the connecting rod mechanism 3 to drive the charging port cover 2 to switch between the open state and the closed state, and improve the intelligent level of switching the charging port cover 2 between the open state and the closed state.

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

[0048] According to some embodiments of the present invention, 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, the second connecting rod 32, the third connecting rod 33 and the fourth connecting rod 34 are all follower rods, and the driving motor 4 drives the connecting rod mechanism 3 to move through the first connecting rod 31. Among them, compared with the second connecting rod 32, the length of the first connecting rod 31 is longer and the distance between it and the charging port cover 2 is closer. Therefore, by driving the first connecting rod 31 to drive the connecting rod mechanism 3 to move by the driving motor 4, the power consumption of the driving motor 4 can be reduced, and the stability of the movement of the connecting rod mechanism 3 can be improved.

[0049] Specifically, when controlling the charging port cover 2 to switch from a closed state to an open state, the output shaft of the driving motor 4 rotates forward, driving the first connecting rod 31 to rotate in a counterclockwise direction 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 an open state; when controlling the charging port cover 2 to switch from an open state to a closed state, the output of the driving motor 4 rotates reversely, driving the first connecting rod 31 to rotate in a clockwise direction 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 a closed state.

[0051] A vehicle according to an embodiment of the second aspect of the present invention includes: a charging port assembly 100 .

[0052] According to the vehicle of the second embodiment of the present invention, the link mechanism 3 can form a double four-link structure with the charging port box 1 and the charging port cover 2 through the first link 31, the second link 32, the third link 33 and the fourth link 34, thereby eliminating the space occupied by the physical rotating shaft, thereby 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 components around the charging port assembly 100. In addition, the double four-link structure has a 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.
