[0059] In all of the examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation on the scope of the application. Thus, other examples of the exemplary embodiments can have different values.

[0060] It should be noted that like reference numerals and characters refer to like items throughout the attached drawings and alternative embodiments thereof, noting that discussion of one item in a drawing does not preclude the further discussion of the same item in another drawing.

[0061] With reference to Figures 1 to 10 The charging port cover structure provided by the embodiments of the present application can be used to charge a battery pack in a vehicle, and the charging port cover structure comprises:

[0062] The outer cover 1 is provided with a driving assembly 11, and the outer cover 1 is configured to be rotatably connected with an external seat plate 6 to realize the opening and closing of the charging port by the outer cover 1. For example, a charging port is arranged on the side wall panel of a vehicle, and when the electric vehicle does not need to be charged, the outer cover 1 covers the charging port, so that the charging port is in a closed state. When the electric vehicle needs to be charged, the outer cover 1 is rotated on the seat plate and then opened from the charging port, so that the charging port is in an open state, so that the charging gun can charge the battery pack of the electric vehicle through the charging port 3.

[0063] With reference to Figure 1 and Figure 2 The connecting piece 4 is in transmission connection with the driving assembly 11, and the connecting piece 4 is configured to move under the driving of the driving assembly 11 and engage with the inner cover of the charging port to realize the separation of the inner cover and the charging port during the opening of the charging port by the outer cover 1.

[0064] Specifically, the charging port cover structure provided by the embodiments of the present application can be applied to flexible opening of the inner cover of the charging port. When the driving assembly 11 drives the connecting piece 4 to move, the connecting piece 4 can engage with the inner cover of the charging port after moving. Since the connecting piece 4 is in transmission connection with the driving assembly 11, the outer cover 1 is combined with the inner cover through the connecting piece 4, so that the movement of the outer cover 1 and the inner cover can be realized synchronously during the opening of the charging port by the outer cover 1, thereby realizing the separation of the inner cover and the charging port, avoiding manual operation of the inner cover by the user when charging the electric vehicle, and improving the convenience of the charging port cover structure during the charging operation.

[0065] Optionally, with reference to Figure 1 and Figure 2 The connecting piece 4 comprises a driven part 41 and a clamping part 42, the driven part 41 is in transmission connection with the driving assembly 11, and the clamping part 42 is configured to be suitable for connecting with the inner cover.

[0066] Specifically, the connecting piece 4 comprises a driven part 41 and a clamping part 42, wherein the driven part 41 is in transmission connection with the driving assembly 11, and the clamping part 42 is configured to be connected with the inner cover. The outer cover 1 is combined with the inner cover through the connecting piece 4, so that the separation of the inner cover and the charging port can be realized synchronously during the opening of the charging port by the outer cover 1, and the user can avoid manually operating the inner cover when charging the electric vehicle, thereby improving the convenience of the charging port cover structure during the charging operation. The process of charging the electric vehicle is simplified, and the charging experience of the user is improved.

[0067] Optionally, referring to Figure 1 , Figure 4 and Figure 5 , the connecting piece 4 has an I-shaped cross section perpendicular to the moving direction thereof.

[0068] Specifically, the driven part 41 at one end of the connecting piece 4 and the clamping part 42 at the other end can be connected through the intermediate connecting segment, and the width dimensions of the driven part 41 and the clamping part 42 can be greater than the width dimension of the connecting segment in the direction perpendicular to the moving direction of the connecting piece 4, so that the connecting piece 4 has an I-shaped structure in the direction perpendicular to the moving direction thereof.

[0069] When the connecting piece 4 is connected with the outer cover 1 and the inner cover, the driven part 41 can be arranged on the side of the outer cover 1 away from the inner cover, and connected with the clamping part 42 through the connecting segment after passing through the outer cover 1, while the clamping part 42 can be clamped in the clamping groove 21 and connected with the driven part 41 after extending out of the clamping groove 21 through the connecting segment. The T-shaped structures are formed between the driven part 41 and the connecting segment and between the clamping part 42 and the connecting segment, which can avoid the driven part 41 from being separated from the outer cover 1 and the clamping part 42 from being separated from the clamping groove 21, thereby ensuring the stability of the connection between the connecting piece 4 and the outer cover 1 and the inner cover.

[0070] Optionally, referring to Figure 5 and Figure 6 , the clamping part 42 is provided with a limiting groove 421.

[0071] Specifically, the driving assembly 11 drives the connecting piece 4 to move through the driven part 41, so that when the clamping part 42 is clamped with the clamping groove 21, the clamping part 42 can be clamped with the clamping groove 21 after sliding into the clamping groove 21, while when the clamping groove 21 has openings at both ends, the clamping part 42 may have a problem of being unable to be clamped with the clamping groove 21 after sliding into the clamping groove 21. The limiting groove 421 can limit the clamping part 42 after the clamping part 42 slides into the clamping groove 21 and reaches the predetermined position for clamping with the clamping groove 21, so as to ensure the accuracy and stability of the clamping position of the clamping part 42 and the clamping groove 21.

[0072] Optionally, referring toFigure 1 and Figure 2 The outer cover 1 comprises a connecting plate 13, and a guide 14 is arranged on the connecting plate 13, and the driven part 41 cooperates with the guide 14 to guide the connecting piece 4.

[0073] Specifically, when the driving assembly 11 on the outer cover 1 drives the driven part 41 to move, in order to ensure the stability of the cooperation between the driving assembly 11 and the driven part 41, the driven part 41 can be slidably connected with the guide 14 in the outer cover 1, and the guide 14 can provide a certain sliding track for the driven part 41, thereby ensuring the stability of the sliding of the driven part 41 relative to the guide 14.

[0074] In addition, referring to Figure 3 The outer cover 1 can comprise an outer plate 12 and a connecting plate 13 which are fixedly connected with each other, such as being clamped with each other or being welded with each other. The outer plate 12 is directly exposed to the outside, and the driving assembly 11 can be arranged on the connecting plate 13, thereby ensuring the connection of the outer cover 1 with the inner cover 2 through the connecting piece 4. The connecting plate 13 is provided with a groove structure, and the driving assembly and the like are arranged in the groove. The outer plate 12 and the groove structure of the connecting plate 13 cooperate to form a cavity structure, and the outer plate can seal the cavity, thereby better protecting the driving assembly and the like from being damaged by external foreign matters.

[0075] Optionally, the guide 14 comprises a first guide and a second guide which are arranged side by side, and the driven part 41 is slidably arranged between the first guide and the second guide.

[0076] Specifically, the side-by-side arrangement of the first guide and the second guide provides the guide 14 with a double-track sliding track, and the driven part 41 can be clamped between the first guide and the second guide during sliding, thereby preventing the driven part 41 from deviating from the first guide and the second guide and ensuring the accuracy of the sliding direction of the driven part 41.

[0077] Optionally, referring to Figure 9 and Figure 10 The first guide comprises two guide rails which are arranged at intervals along the sliding direction of the driven part 41, and the driven part 41 slides along the two guide rails.

[0078] Specifically, the two guide rails can extend in the same direction, so that when the driven part 41 slides along the two guide rails, the driven part 41 can be in sliding fit with any one of the guide rails. When a plurality of inner covers are arranged in the charging port, one guide rail can correspond to one inner cover, so that when the driven part 41 is in sliding fit with one guide rail, the corresponding inner cover and the charging port can be separated, improving the flexibility of the charging port cover structure for opening different inner covers.

[0079] In addition, the second guide can have the same structure as the first guide, for example, the second guide includes two guide rails arranged at intervals along the sliding direction of the driven part 41, and the driven part 41 slides along the two guide rails.

[0080] Optionally, referring to Figure 4 and Figure 5 , the driven part 41 is a rack, and the guide rails are arranged on the bottom plate of the connecting plate 13, i.e. the guide rails are arranged on the bottom of the groove formed on the connecting plate 13, and the guide rails are provided with a first limiting part away from the bottom plate, and the rack is arranged between the first limiting part and the bottom plate to limit the rack away from the bottom plate.

[0081] Specifically, when the driven part 41 is in sliding fit with the guide rail, in order to avoid the driven part 41 from falling off the guide rail, a first limiting part can be arranged on the side of the guide rail away from the bottom plate, which can be an edge structure on the side of the guide rail away from the bottom plate. The edge structure of the first limiting part limits the driven part 41 on the guide rail, avoiding the rack moving away from the bottom plate, and ensuring the stability of the sliding fit between the driven part 41 and the guide rail.

[0082] Optionally, referring to Figures 2 to 4 , the driving assembly 11 includes a motor 111 and a second gear 112 connected to the output shaft of the motor 111, and the second gear 112 is in transmission connection with the rack.

[0083] Specifically, when the driving assembly 11 is actuated and drives the driven part 41 to move, the motor 111 can drive the second gear 112 to rotate through the output end after starting. Since the second gear 112 is in meshing engagement with the driven part 41, the second gear 112 can drive the driven part 41 to move when rotating, and further drive the entire connecting piece 4 to move. Moreover, by adjusting the rotating direction of the second gear 112, the direction of the movement of the driven part 41 can also be controlled, so as to realize the clamping and separation of the clamping part 42 and the clamping groove 21, and ensure the automatic and synchronous opening of the inner cover 2 with the outer cover 1.

[0084] In addition, the driving assembly 11 can also be a screw structure connected to the motor, and the screw is in cooperation with the driven part 41. When the motor drives the screw to rotate, the driven part 41 can also be driven to move.

[0085] Optionally, the charging port cover structure further comprises at least one first gear, which is arranged on the first limiting portion and in transmission connection with the rack.

[0086] Specifically, when the driven portion 41 slides on the guide rail, as the rack structure of the driven portion 41 is long, in order to avoid the driven portion 41 from being deviated during the sliding process, a first gear can be arranged on the first limiting portion, and the first limiting portion is in transmission connection with the rack, so as to balance the stability of both ends of the driven portion 41 during the movement, as shown in the figure, and at the same time, the movement of the rack away from the bottom plate can also be limited. Figure 10

[0087] Optionally, the first gear is two, and the two first gears are arranged on both sides of the second gear 112 respectively.

[0088] Specifically, when the second gear 112 drives the driven portion 41 to move, as the action of the second gear 112 is rotation but not movement, it makes the driven portion 41 close to or away from the second gear 112 during the movement. In order to avoid the driven portion 41 from being warped or deviated and other problems when the second gear 112 is in engagement with the end portion of the driven portion 41, two first gears can be arranged on both sides of the second gear 112 respectively, so as to ensure that the driven portion 41 is always in cooperation with two gears, and the stability of the movement of the driven portion 41 is ensured.

[0089] Optionally, a through hole is arranged on the connecting plate 13, and the connecting piece 4 further comprises an intermediate segment connecting the driven portion 41 and the clamping portion 42.

[0090] The intermediate segment is arranged in the through hole, and the driven portion 41 and the clamping portion 42 are arranged on both sides of the connecting plate 13 respectively.

[0091] Specifically, when the connecting piece 4 is connected with the outer cover 1 and the inner cover, the driven portion 41 can be arranged on the outer side of the connecting plate 13, and is connected with the clamping portion 42 through the connecting segment after penetrating through the connecting plate 13, while the clamping portion 42 can be clamped in the clamping groove 21 and connected with the driven portion 41 after extending out of the clamping groove 21 through the connecting segment. When the driven portion 41 and the clamping portion 42 are arranged on both sides of the connecting plate 13 respectively, the driven portion 41 can be prevented from being separated from the connecting plate 13, and the clamping portion 42 can be prevented from being separated from the clamping groove 21, so as to ensure the stability of the connection between the connecting piece 4 and the connecting plate 13.

[0092] The embodiment of the present application further provides a charging port structure, which comprises the charging port cover structure, and further comprises a seat plate 6 and at least one inner cover 2.

[0093] ​The seat plate 6 is provided with a charging port 3 corresponding to the charging end of the vehicle; the inner cover 2 is detachably connected with the charging port 3;

[0094] The outer cover 1 is rotatably connected with the seat plate 6, and when the outer cover 1 is switched from the closed state to the open state, the driving assembly 11 drives the connecting piece 4 to move so as to make the connecting piece 4 engage with the inner cover 2, and the outer cover 1 drives the inner cover 2 to move to realize the separation of the inner cover 2 from the charging port 3.

[0095] Specifically, referring to Figures 1 to 3 , the inner cover 2 is detachably connected to the charging port 3, and the side of the inner cover 2 close to the outer cover 1 is provided with a clamping groove 21; for example, the inner cover 2 is clamped on the charging port 3 through interference fit, so as to form a seal of the inner cover 2 on the charging port 3.

[0096] Referring to Figure 4 , one end of the connecting piece 4 forms a driven part 41 matched with the driving assembly 11, and the other end of the connecting piece 4 forms a clamping part 42 matched with the clamping groove 21; when the driving assembly 11 acts, the driven part 41 can be driven to move, and the clamping part 42 will also be driven to move towards the clamping groove 21 while the whole connecting piece 4 moves, so as to realize the clamping and matching of the clamping part 42 and the clamping groove 21, and then realize that the outer cover 1 drives the inner cover 2 to be taken off from the charging port 3 through the connecting piece 4.

[0097] When the outer cover 1 is switched from the closed state to the open state, the driving assembly 11 drives the connecting piece 4 to move through the driven part 41, and the clamping part 42 is clamped with the clamping groove 21, that is, the driven part 41 at one end of the connecting piece 4 is connected to the outer cover 1, and the clamping part 42 at the other end of the connecting piece 4 is connected to the inner cover 2, so that the outer cover 1 drives the inner cover 2 to be taken off from the charging port 3 through the connecting piece 4 during the opening process, realizes that the inner cover 2 is automatically and synchronously opened with the outer cover 1, avoids that the user manually operates the inner cover 2 when charging the electric vehicle, improves the convenience of the charging port structure during the charging operation, simplifies the process of charging the electric vehicle, and improves the charging experience of the user.

One end of the connecting piece 4 is formed with a driven part 41 matched with the driving assembly 11, and the other end of the connecting piece 4 is formed with a clamping part 42 matched with the clamping groove 21. When the outer cover 1 is switched from the closed state to the open state, the driving assembly 11 drives the connecting piece 4 to move through the driven part 41, and the clamping part 42 is clamped with the clamping groove 21, so that the outer cover 1 drives the inner cover 2 to separate from the charging port 3 through the connecting piece 4, the synchronous opening of the inner cover 2 with the outer cover 1 is realized, the user manually operates the inner cover 2 when charging by using the charging port structure is avoided, the operation process of the charging port structure during charging is simplified, and the charging experience of the user is improved.

[0102] In addition, in order to prevent the limiting protrusion structure 22 from hindering the sliding of the clamping portion 42 in the clamping slot 21 when the clamping portion 42 and the clamping slot 21 are not clamped to the predetermined position, a sliding groove can be provided on the limiting groove 421. The limiting groove 421 is a groove provided in the middle of the sliding groove, such as Figure 5 shown.

[0103] Alternatively, see Figure 7 and Figure 8 The limiting protrusion structure 22 includes a sleeve 221, an elastic member 222 and a protrusion 223. The sleeve 221 is fixed in the inner cover 2, and the elastic member 222 is arranged in the sleeve 221. The first end of the protrusion 223 is connected to the elastic member 222, and the second end of the protrusion 223 extends from the through hole of the sleeve 221 and protrudes from the inner wall surface of the slot 21.

[0104] Specifically, the sleeve 221 can be a cylindrical structure with one side open, the elastic member 222 is disposed within the sleeve 221, and the protrusion 223 can be a T-shaped structure. The first end of the protrusion 223 is connected to the elastic member 222 and is confined within the sleeve 221. The second end of the protrusion 223 extends from a through hole on one side of the sleeve 221 and extends into the slot 21. The portion of the protrusion 223 extending into the slot 21 can be hemispherical. When the clamping portion 42 and the slot 21 are clamped to a predetermined position, the protrusion 223 can be clamped into the limiting groove 421 to limit the clamping portion 42 and the slot 21, thereby improving the positional accuracy and stability of the clamping portion 42 and the slot 21.

[0105] The limiting protrusion structure 22 may also be merely a fixed protrusion fixed on the card slot 21 , which can also ensure the stability of the card connection between the clamping portion 42 and the card slot 21 when the fixed protrusion and the limiting slot 421 are nested.

[0106] Alternatively, see Figure 7 and Figure 8 The edge of the through hole of the sleeve 221 forms a second limiting portion, and the protrusion 223 is provided with a limiting boss. The limiting boss is located in the sleeve 221 and cooperates with the second limiting portion.

[0107] It can be understood that the limiting groove 421 is a concave spherical structure, and the protrusion 223 is a spherical protrusion adapted to the spherical structure; further, the card slot 21 is a groove structure adapted to the lower half of the "I"-shaped structure, and the spherical protrusion at least partially protrudes from the bottom of the groove structure; it can be understood that when the clamping portion and the card slot 21 are in the engaged state, the groove structure can enable the card slot 21 to better receive the force exerted by the clamping portion on it to keep it away from the charging port.

[0108] Specifically, the first end of the protrusion 223 is connected to the elastic member 222 and is limited in the sleeve 221, and specifically, the through hole edge of the sleeve 221 forms a second limiting portion, and the limiting boss is located in the sleeve 221, and the circumferential dimension of the limiting boss is located between the internal space of the sleeve 221 and the opening of the through hole, so that the limiting boss is stopped by the second limiting portion in the internal space of the sleeve 221, forming a limiting fit of the limiting boss and the second limiting portion, avoiding the limiting boss from being taken out of the internal space of the sleeve 221.

[0109] Optionally, referring to Figures 3 to 6 , the inner cover 2 includes a first inner cover 23 and a second inner cover 24, and the charging port 3 includes a first charging port 31 and a second charging port 32, the first inner cover 23 is detachably connected to the first charging port 31, and the second inner cover 24 is detachably connected to the second charging port 32.

[0110] The clamping groove 21 includes a first clamping groove 211 arranged on the first inner cover 23 and a second clamping groove 212 arranged on the second inner cover 24.

[0111] The driving assembly 11 drives the connecting piece 4 to move in the first direction, so that the clamping portion 42 is clamped and matched with the first clamping groove 211.

[0112] Alternatively, the driving assembly 11 drives the connecting piece 4 to move in the second direction, so that the clamping portion 42 is clamped and matched with the second clamping groove 212.

[0113] Specifically, the driving assembly 11 can drive the connecting piece 4 to move in the first direction and make the clamping portion 42 clamped and matched with the first clamping groove 211, and the outer cover 1 can take off the first inner cover 23 from the first charging port 31, realizing the separation of the first inner cover 23 and the first charging port 31.

[0114] The driving assembly 11 can drive the connecting piece 4 to move in the second direction and make the clamping portion 42 clamped and matched with the second clamping groove 212, and the outer cover 1 can take off the second inner cover 24 from the second charging port 32, realizing the separation of the second inner cover 24 and the second charging port 32.

[0115] Specifically, in the case that the outer cover 1 is switched from the closed state to the open state, the driving assembly 11 can drive the connection piece 4 to move, and when the clamping portion 42 is clamped with the clamping groove 21, the outer cover 1 drives the inner cover 2 to be removed from the charging port 3 through the connection piece 4, so as to realize the synchronous opening of the inner cover 2 with the outer cover 1. When the charging port 3 includes two charging ports of the first charging port 31 and the second charging port 32, the driving assembly 11 drives the connection piece 4 to move, so as to realize that one of the first charging port 31 and the second charging port 32 is opened, and the other is kept closed.

[0116] Further, in the case that the outer cover is switched from the open state to the closed state, the outer cover can drive the inner cover to move, so as to connect the inner cover with the corresponding charging port.

[0117] In the case that the connection piece 4 moves along the first direction, the first direction can be Figure 6 the left moving direction, and the clamping portion 42 is clamped with the first clamping groove 211, the outer cover 1 drives the first inner cover 23 to be removed from the first charging port 31, so as to charge the battery pack through the first charging port 31, and at the same time, the second inner cover 24 is connected to the second charging port 32, so as to avoid the external impurities from entering into the second charging port 32.

[0118] In the case that the connection piece 4 moves along the second direction, the second direction can be Figure 6 the right moving direction, and the clamping portion 42 is clamped with the second clamping groove 212, the outer cover 1 drives the second inner cover 24 to be removed from the second charging port 32, so as to charge the battery pack through the second charging port 32, and at the same time, the first inner cover 23 is connected to the first charging port 31, so as to avoid the external impurities from entering into the first charging port 31.

[0119] Optionally, the charging port structure further includes a controller, and the controller is used to control the driving assembly 11 to drive the connection piece 4 to move along the first direction or along the second direction.

[0120] Specifically, the charging port 3 includes two charging ports, i.e., a first charging port 31 and a second charging port 32. For example, the first charging port 31 can be a fast charging port, and the second charging port 32 can be a slow charging port. When the vehicle needs to be fast charged, the controller can identify a fast charging signal, such as the controller identifying that a fast charging gun is close to the charging port. At this time, the controller can control the rotating direction of the output end of the motor 111, so that the motor 111 drives the second gear 112 to rotate in the clockwise direction, the connecting piece 4 moves in the first direction, and the outer cover 1 drives the first inner cover 23 to be removed from the first charging port 31. When the vehicle needs to be slow charged, the controller can identify a slow charging signal, such as the controller identifying that a slow charging gun is close to the charging port. At this time, the controller can control the rotating direction of the output end of the motor 111, so that the motor 111 drives the second gear 112 to rotate in the counterclockwise direction, the connecting piece 4 moves in the second direction, and the outer cover 1 drives the second inner cover 24 to be removed from the second charging port 32.

[0121] The controller can be arranged in the outer cover 1. The controller is provided with a charging gun sensor, such as a magnetic field sensor, which is used to sense the charging power of the charging gun. That is, compared with the conventional scheme of opening the outer cover by using an actuator, the opening and closing of the outer cover 1 of the present application is completely controlled by the controller, and the manual mechanical operation of opening the inner cover 2 during the charging process is avoided.

[0122] Optionally, the charging power of the charging terminal of the first charging port 31 is greater than or equal to 40 KW, and the charging power of the charging terminal of the second charging port 32 ranges from 3 KW to 10 KW.

[0123] Specifically, in order to meet the charging needs of different users, the first charging port 31 and the second charging port 32 can be respectively arranged as charging ports with different charging powers. For example, the first charging port 31 can be a high-power direct-current fast charging port, and the charging power of the charging terminal of the first charging port 31 can reach 40 KW or even higher, so as to reduce the waiting time of the user during charging. The second charging port 32 can be a low-power alternating-current slow charging port, and the charging power of the charging terminal of the second charging port 32 can be 3 KW or 7 KW, so that the user can charge the battery pack at home through the charging port structure, avoiding the user going to the charging station to charge.

[0124] Optionally, the inner cover 2 is in interference fit with the charging port 3. Specifically, the inner cover 2 can be clamped on the charging port 3 through interference fit. On the one hand, the interference fit can ensure that the inner cover 2 seals the charging port 3, and on the other hand, the interference fit can improve the stability of the inner cover 2 arranged on the charging port 3, avoiding the inner cover 2 from falling off the charging port 3.

[0125] The embodiment of the present application provides a vehicle, which comprises a battery pack and the charging port structure.

[0126] Specifically, the charging port 3 of the charging port structure can be electrically connected with the battery pack.

[0127] Specifically, referring to Figure 3 , the vehicle is provided with a charging port on a side wall panel 5, an outer cover 1 of the charging port structure is openably connected to the charging port, an inner cover 2 is detachably connected to the charging port 3, and a clamping groove 21 is arranged on one side of the inner cover 2 close to the outer cover 1. One end of a connecting piece 4 forms a driven part 41 engaged with the driving assembly 11, and the other end of the connecting piece 4 forms a clamping part 42 clamped with the clamping groove 21. When the outer cover 1 is switched from the closed state to the open state, the driving assembly 11 drives the connecting piece 4 to move through the driven part 41, and the clamping part 42 is clamped with the clamping groove 21, so that the outer cover 1 drives the inner cover 2 to separate from the charging port 3 through the connecting piece 4, the synchronous opening of the inner cover 2 with the outer cover 1 is realized, manual operation of the inner cover 2 by a user when the charging port structure is used for charging is avoided, the operation process of the vehicle when charging is simplified, and the charging experience of the user is improved.

[0132] Optionally, the step of controlling the first inner cover or the second inner cover to open according to the charging gun type comprises the following steps:

[0133] the charging gun type is a first charging gun matched with the first charging port;

[0134] controlling a driving assembly to drive the connecting piece to move in a first direction, so that the connecting piece is engaged with the first inner cover, and then when the outer cover is opened, the first inner cover is separated from the first charging port;

[0135] Alternatively, the charging gun type is a second charging gun matched with the second charging port;

[0136] The control driving assembly drives the connecting piece to move in a second direction to engage the connecting piece with the second inner cover, so that the second inner cover is separated from the second charging port when the outer cover is opened.

[0137] Specifically, the first charging port is provided with a first charging terminal, and the charging gun type matched with the first charging port can be that the charging gun is matched with the first charging terminal in the first charging port or that the charging gun is matched with the shape of the first charging port; the second charging port is provided with a second charging terminal, and the charging gun type matched with the second charging port can be that the charging gun is matched with the second charging terminal in the second charging port or that the charging gun is matched with the shape of the second charging port.

[0138] The opening method of the inner cover in the charging port cover structure can open the first inner cover or the second inner cover according to the charging gun type, so as to selectively open the first charging port and the second charging port and ensure the convenience of charging the vehicle through the first charging port and the second charging port.
