[0048] In all of the examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as a limitation on the scope of the exemplary embodiments. Thus, other examples of the exemplary embodiments can have different values.

[0049] It should be noted that like reference numerals and letters refer to like items throughout the accompanying drawings, and as a result, further discussion of such items is unnecessary in subsequent drawings.

[0050] Reference Figures 1 to 4The embodiment of the present application provides a charging port cover structure which can be used for charging a battery pack in a vehicle, and the charging port cover structure comprises:

[0051] An outer cover 1 is provided with a first magnetic assembly 11, and the outer cover 1 is configured to be rotatably connected with a seat plate, so as to realize opening and closing of the charging port by the outer cover 1. For example, a charging port is arranged on a side wall panel of the vehicle, and when the electric vehicle does not need to be charged, the outer cover 1 is arranged on 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 opened from the charging port after being rotated on the seat plate, so that the charging port is in an open state, so that the charging gun charges the battery pack of the electric vehicle through the charging port 3.

[0052] The first magnetic assembly 11 is configured to be combined with an inner cover of the charging port, so as to realize separation of the inner cover and the charging port during opening of the charging port by the outer cover 1. For example, when one or more charging ports are arranged in the charging port, a magnet or a magnetic conductor such as an iron block can be arranged on the inner cover of each charging port. The first magnetic assembly 11 can be matched with the magnet or the magnetic conductor on the inner cover, so as to combine the outer cover 1 and the inner cover together, so as to realize synchronous separation of the inner cover and the charging port during opening of the charging port by the outer cover 1, thereby avoiding manual operation of the inner cover by a user when the electric vehicle is charged, improving convenience of the charging port cover structure during charging operation. The process of charging the electric vehicle is simplified, and the charging experience of the user is improved.

[0053] Optionally, the first magnetic assembly 11 is an electromagnet.

[0054] Specifically, the first magnetic assembly 11 can include an iron core 111 and a coil 112. In the case that the outer cover 1 is in a closed state, no current flows in the coil 112, so that opening of the outer cover 1 will not pull the inner cover out of the charging port. In the case that the outer cover 1 is switched from the closed state to an open state, current can flow in the coil 112, and the iron core 111 is matched with a magnetic part on the inner cover in a magnetic attraction mode. After the outer cover 1 is combined with the inner cover, the inner cover can be pulled out of the charging port by the outer cover 1 when the outer cover 1 is opened, so as to ensure synchronous opening of the inner cover and the outer cover 1.

[0055] Optionally, referring to Figure 1 and Figure 2 An outer cover protrusion 10 is arranged on the outer cover 1, the outer cover protrusion 10 is provided with a first recess, and the first magnetic assembly 11 is arranged in the first recess.

[0056] Specifically, the first recess on the outer cover protrusion 10 can have an opening facing the inner cover, and the first magnetic component 11 is embedded in the first recess. The first recess can limit the first magnetic component 11 with its circumferential sidewall to ensure the stability of the arrangement of the first magnetic component 11 in the first recess. In addition, when multiple first magnetic components 11 are arranged, multiple first recesses can also be arranged, and each first magnetic component 11 is embedded in one first recess.

[0057] Referring to Figure 2 , the application also provides a charging port structure, which comprises the charging port cover structure, and further comprises:

[0058] The seat plate 6 and the at least one inner cover 2; the outer cover 1 is rotatably connected with the seat plate 6, and 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.

[0059] When the outer cover 1 is switched from the closed state to the open state, the first magnetic component 11 is combined with the inner cover 2 to separate the inner cover 2 from the charging port 3.

[0060] Specifically, the inner cover 2 can be provided with a magnet or a magnetic conductor such as an iron block, and the first magnetic component 11 can cooperate with the magnet or the magnetic conductor on the inner cover 2 to combine the outer cover 1 and the inner cover 2 together, so as to simultaneously realize the separation of the inner cover 2 from the charging port 3 in the process of opening the charging port by the outer cover 1, thereby avoiding the manual operation of the inner cover 2 by the user when charging the electric vehicle and improving the convenience of the charging port structure during the charging operation. Simplify the process of charging the electric vehicle and improve the charging experience of the user.

[0061] Optionally, referring to Figure 1 and Figure 2 , the inner cover 2 is provided with a second magnetic component 21;

[0062] When the outer cover 1 is switched from the closed state to the open state, the first magnetic component 11 is magnetically attracted to the second magnetic component 21 to separate the inner cover 2 from the charging port 3.

[0063] Specifically, referring to Figure 1 and Figure 2The inner cover 2 is detachably connected to the charging port 3, and the second magnetic assembly 21 is arranged on one side of the inner cover 2 close to the outer cover 1. For example, the inner cover 2 is clamped on the charging port 3 through interference fit, so that the inner cover 2 seals the charging port 3, and when the second magnetic assembly 21 is attracted to the first magnetic assembly 11, the outer cover 1 drives the inner cover 2 to be removed from the charging port 3, so as to separate the inner cover 2 from the charging port 3.

[0064] Referring to Figure 2 When the outer cover 1 is switched from the closed state to the open state, the first magnetic assembly 11 is magnetically attracted to the second magnetic assembly 21. Specifically, the coil in the first magnetic assembly 11 is energized, and the electromagnetic action generated by the first magnetic assembly 11 attracts the second magnetic assembly 21. The outer cover 1 can drive the inner cover 2 to separate from the charging port 3 under the cooperation of the first magnetic assembly 11 and the second magnetic assembly 21, so as to automatically and synchronously open the inner cover 2 with the outer cover 1. This avoids manual operation of the inner cover 2 by the user when charging the electric vehicle, improves the convenience of the charging port structure during charging operation, simplifies the charging process of the electric vehicle, and improves the charging experience of the user.

[0065] In addition, referring to Figure 2 The outer cover 1 can include an outer plate 12 and a connecting plate 13 fixedly connected to each other, such as clamped or welded to each other. The outer plate 12 is directly exposed to the outside, and the first magnetic assembly 11 can be arranged on the inner side of the connecting plate 13, so as to ensure the magnetic attraction between the first magnetic assembly 11 and the second magnetic assembly 21.

[0066] The charging port structure provided by the embodiment of the application includes an outer cover 1, an inner cover 2 and a charging port 3. The inner side of the outer cover 1 is provided with a first magnetic assembly 11. The outer cover 1 is configured to be openably connected to the charging port. The inner cover 2 is detachably connected to the charging port 3. The inner cover 2 is provided with a second magnetic assembly 21 on one side close to the outer cover 1. When the outer cover 1 is switched from the closed state to the open state, the first magnetic assembly 11 is magnetically attracted to the second magnetic assembly 21. The electromagnetic action generated by the first magnetic assembly 11 attracts the second magnetic assembly 21. The outer cover 1 can drive the inner cover 2 to separate from the charging port 3 under the cooperation of the first magnetic assembly 11 and the second magnetic assembly 21, so as to synchronously open the inner cover 2 with the outer cover 1. This avoids manual operation of the inner cover 2 by the user when charging the electric vehicle, simplifies the operation process of the charging port structure during charging, and improves the charging experience of the user.

[0067] Optionally, the first magnetic assembly 11 and the second magnetic assembly 21 are correspondingly arranged.

[0068] Specifically, in the case that the outer cover 1 is in the closed state, the first magnetic assembly 11 and the second magnetic assembly 21 can be opposite, at this time, there is no mutual magnetic attraction or the mutual magnetic attraction is small between the first magnetic assembly 11 and the second magnetic assembly 21, and the opening of the outer cover 1 will not pull the inner cover out of the charging port; in the case that the outer cover 1 is switched from the closed state to the open state, the first magnetic assembly 11 can be connected with current, the magnetic attraction force is generated between the first magnetic assembly 11 and the second magnetic assembly 21, the relative position between the first magnetic assembly 11 and the second magnetic assembly 21 can be kept fixed under the magnetic attraction of the first magnetic assembly 11 and the second magnetic assembly 21, and the inner cover 2 can be pulled out of the charging port 3 by the outer cover 1 after the outer cover 1 and the inner cover 2 are combined, which ensures that the inner cover 2 is opened synchronously with the outer cover 1.

[0069] Optionally, the first magnetic assembly 11 is an electromagnet, and the second magnetic assembly 21 is a permanent magnet.

[0070] In the case that the outer cover 1 is switched from the closed state to the open state, the electromagnet and the permanent magnet are magnetically connected.

[0071] Referring to Figure 1 , the first magnetic assembly 11 can include an iron core 111 and a coil 112, the second magnetic assembly 21 is a permanent magnet, the iron core 111 is opposite to the permanent magnet, and the coil 112 is wound on the iron core 111;

[0072] In the case that the outer cover 1 is switched from the closed state to the open state, current is connected in the coil 112, so that the polarity of the opposite ends of the iron core 111 and the permanent magnet is opposite.

[0073] Specifically, in the case that the outer cover 1 is in the closed state, the iron core 111 can be opposite to the permanent magnet, and no current is passed through the coil 112, at this time, the magnetic attraction force between the permanent magnet and the iron core 111 can be set to be small, so that the inner cover 2 cannot be pulled out from the charging port 3; in the case that the outer cover 1 is switched from the closed state to the open state, current can be passed through the coil 112, and the polarity of the iron core 111 opposite to the permanent magnet can increase the magnetic attraction force between the iron core 111 and the permanent magnet, in the case that the iron core 111 and the permanent magnet keep opposite and the position is relatively fixed, the inner cover 2 can be pulled out from the charging port 3 when the outer cover 1 is opened, by using the cooperation of the permanent magnet and the first magnetic component, it is ensured that the inner cover 2 is opened synchronously with the outer cover 1, and the convenience of the charging port structure during charging operation is improved.

[0074] Optionally, the first magnetic component 11 is an electromagnet, and the second magnetic component 21 is a magnetic conductor.

[0075] In the case that the outer cover 1 is switched from the closed state to the open state, the electromagnet is magnetically connected with the magnetic conductor.

[0076] Specifically, the first magnetic component 11 can include an iron core 111 and a coil 112, the second magnetic component 21 is a magnetic conductor, the iron core 111 is opposite to the magnetic conductor, and the coil 112 is wound around the iron core 111.

[0077] In the case that the outer cover 1 is switched from the closed state to the open state, current is passed through the coil 112, so that the iron core 111 is magnetically connected with the magnetic conductor.

[0078] Specifically, the magnetic conductor can be an iron block or a nickel block that can be attracted by a magnet, in the case that the outer cover 1 is in the closed state, the iron core 111 can be opposite to the magnetic conductor, and no current is passed through the coil 112, at this time, there is no interaction force between the magnetic conductor and the iron core 111, that is, at this time, the inner cover 2 cannot be pulled out from the charging port 3; in the case that the outer cover 1 is switched from the closed state to the open state, current can be passed through the coil 112, the iron core 111 and the coil 112 form an electromagnet and generate an electromagnetic field, and the magnetic attraction force between the iron core 111 and the magnetic conductor is generated, in the case that the iron core 111 and the magnetic conductor keep opposite and the position is relatively fixed under the magnetic attraction force between the iron core 111 and the magnetic conductor, the inner cover 2 can be pulled out from the charging port 3 when the outer cover 1 is opened, by using the cooperation of the magnetic conductor and the first magnetic component, it is ensured that the inner cover 2 is automatically opened with the outer cover 1, and the convenience of the charging port structure during charging operation is improved.

[0079] Optionally, the charging port structure further comprises a controller 4 and a rotating shaft 5 connected with each other, the outer cover 1 is connected to the seat plate 6 through the rotating shaft 5, and the first magnetic component 11 is electrically connected with the controller 4.

[0080] The controller 4 is configured to, when the outer cover 1 is switched from the closed state to the open state, control the first magnetic component 11 to be powered to enable the first magnetic component 11 to be magnetically connected with the second magnetic component 21.

[0081] Specifically, the charging port structure can comprise a seat plate 6 as a frame shell, the outer cover 1 can be connected to the seat plate 6 of the charging port through the rotating shaft 5, the controller 4 can also be fixed on the seat plate 6, and the controller 4 has an output end coaxially fixed with the rotating shaft 5. When the vehicle needs to be charged, the controller 4 can drive the rotating shaft 5 to rotate and open the outer cover 1, and the controller 4 can simultaneously power the first magnetic component 11, so that the first magnetic component 11 is magnetically connected with the second magnetic component 21, so that the inner cover 2 can be pulled out of the charging port 3 when the outer cover 1 is opened, and the automatic opening of the inner cover 2 with the outer cover 1 is ensured. 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 in the present application are completely controlled by the controller 4, and the manual mechanical operation of opening the inner cover 2 during charging is avoided.

[0082] In addition, referring to Figure 2 , the charging port 3 is arranged in the seat plate 6, and the edge of the charging port 3 in the seat plate 6 can be provided with a sealing soft rubber 7, which can abut against the sealing soft rubber 7 when the inner cover 2 is clamped on the charging port 3, so as to ensure that the inner cover 2 seals the charging port 3.

[0083] Referring to Figure 2 , the outer edge of the opening for charging on the seat plate 6 can be provided with a seat plate soft rubber 8, which can be tightly attached to the seat plate soft rubber 8 when the outer cover 1 is connected to the seat plate 6 of the charging port through the rotating shaft 5, so as to ensure the sealing property of the outer cover 1 to the charging port.

[0084] Optionally, referring to Figure 1 and Figure 2 , the inner cover 2 comprises a first inner cover 22 and a second inner cover 23, the charging port 3 comprises a first charging port 31 and a second charging port 32, the first inner cover 22 is detachably connected to the first charging port 31, and the second inner cover 23 is detachably connected to the second charging port 32.

[0085] Specifically, the first magnetic assembly 11 comprises a first electromagnetic assembly and a second electromagnetic assembly, the inner cover 2 comprises a first inner cover 22 and a second inner cover 23, the second magnetic assembly 21 comprises a first magnetic piece arranged on the first inner cover 22 and a second magnetic piece arranged on the second inner cover 23, the charging port 3 comprises a first charging port 31 and a second charging port 32, the first inner cover 22 is detachably connected to the first charging port 31, and the second inner cover 23 is detachably connected to the second charging port 32.

[0086] In the case of charging through the first charging port 31, the controller 4 charges the first coil in the first electromagnetic assembly to make the first electromagnetic assembly and the first magnetic piece magnetically attract, and the first inner cover 22 is separated from the first charging port 31.

[0087] In the case of charging through the second charging port 32, the controller 4 charges the second coil in the second electromagnetic assembly to make the second electromagnetic assembly and the second magnetic piece magnetically attract, and the second inner cover 23 is separated from the second charging port 32.

[0088] Specifically, the first electromagnetic assembly can comprise a first iron core and a first coil wound on the first iron core, and the second electromagnetic assembly can comprise a second iron core and a second coil wound on the second iron core, and the first coil and the second coil can be electrically connected to the controller 4.

[0089] In the case that the outer cover 1 is in the closed state, the first iron core can be opposite to the first magnetic piece, and the second iron core can be opposite to the second magnetic piece, at this time, the first coil and the second coil can not be electrified; in the case that the outer cover 1 is switched from the closed state to the open state, the controller 4 can select one of the first coil and the second coil to be electrified according to the type of charging required, thereby opening one of the first inner cover 22 and the second inner cover 23, while the other is still connected to the charging port.

[0090] 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 4 can send a fast charging signal. For example, the controller 4 identifies that the fast charging gun is close to the charging port, that is, in the case of charging through the first charging port 31, the controller 4 can charge the first coil in the first electromagnetic assembly and not charge the second coil, so that the first electromagnetic assembly is magnetically attracted to the first magnetic part, the first inner cover 22 is removed from the first charging port 31, so that the charging gun charges the battery pack through the first charging port 31, and at the same time, the second inner cover 23 is connected to the second charging port 32, avoiding external impurities entering the second charging port 32. When the vehicle needs to be slow charged, that is, in the case of charging through the second charging port 32, the controller 4 charges the second coil in the second electromagnetic assembly and not charges the first coil, so that the second electromagnetic assembly is magnetically attracted to the second magnetic part, the second inner cover 23 is removed from the second charging port 32, so that the charging gun charges the battery pack through the second charging port 32, and at the same time, the first inner cover 22 is connected to the first charging port 31, avoiding external impurities entering the first charging port 31.

[0091] In addition, the first inner cover 22 can be connected to the first charging port 31 by interference fit, and the second inner cover 23 can be connected to the second charging port 32 by interference fit, so as to ensure the sealing performance of the first charging port 31 and the second charging port 32 when they are closed.

[0092] Optionally, the charging power of the charging terminal of the first charging port 31 is greater than or equal to 40KW, and the charging power of the charging terminal of the second charging port 32 ranges from 3KW to 10KW.

[0093] 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 set 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 40KW or even higher, so as to reduce the waiting time of the user when 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 3KW or 7KW, so that the user can charge the battery pack at home through the charging port structure, avoiding going to the charging station to charge.

[0094] Optionally, the controller 4 is provided with a charging gun sensor, and the charging gun sensor is used to sense the type of the charging gun.

[0095] Specifically, the controller 4 can identify the type of the charging gun through the charging gun sensor. For example, the charging gun sensor can be a magnetic field sensor, which can convert various magnetic fields and their changes into electrical signals, so that the controller 4 can identify the size of the induced magnetic field generated by the coil in different charging guns through the magnetic field sensor, and then achieve the purpose of identifying the type of the charging gun. After automatically identifying the charging gun, the controller 4 can transmit the identification induction signal of the charging gun to the control chip on the vehicle, and the control chip sends a command to the controller 4 to open the first inner cover 22 or the second inner cover 23, thereby realizing the selective opening of the first charging port 31 and the second charging port 32, and ensuring the flexibility of opening the first charging port 31 and the second charging port 32.

[0096] Optionally, referring to Figure 1 and Figure 4 , the inner cover 2 is provided with an inner cover protrusion 9 on the side close to the outer cover 1, the inner cover protrusion 9 is provided with a second groove with an opening facing the outer cover 1, and the second magnetic component 21 is embedded in the second groove.
