In the application, when the charger is pulled out after charging is completed, since the charging interface piece 4 is arranged to be telescopic at the mounting port 2, the force of the charger on the charging interface piece 4 can drive the charging interface piece 4 to move from the inside of the mounting carrier 1 to the outside, the cover driving unit is in transmission connection with the charging interface piece 4 and the cover 3, when the charging interface piece 4 moves from the inside of the mounting carrier 1, the cover driving unit applies a force to the cover 3 in the closing direction, so that the closing of the cover 3 after the charger is pulled out is realized, and the closing of the charging interface to avoid foreign matter from entering is realized.

[0042] In addition, the closing of the cover 3 is automatically performed, in other words, the closing of the cover 3 can be realized as long as the charging interface piece 4 is pulled out, and it can be seen that the charging interface device provided by the specific embodiment of the application has high convenience, thereby greatly improving the use experience of the passenger.

[0044] It can be understood by those skilled in the art that, in addition to the sliding opening and closing mode described above, the cover 3 can also adopt a rotating opening and closing mode, but the sliding opening and closing mode can be used on the automobile seat to arrange the cover 3 in the mounting carrier 1, thereby saving space, and the various opening and closing modes of the cover 3 described above all belong to the protection scope of the application.

[0045] As shown in FIGS. 1, 2 and 3, the charging interface device comprises a mounting carrier 1, a charging interface piece 4 and a cover 3. Figure 3 and Figure 4 As shown in FIGS. 1, 2 and 3, the charging interface device comprises a mounting carrier 1, a charging interface piece 4 and a cover 3.

[0046] In some embodiments, the cover driving unit comprises a slide structure 5, on which a first slide rail 51 and a second slide rail 52 are formed, the extending directions of the first slide rail 51 and the second slide rail 52 are perpendicular to each other, the first slide rail 51 is arranged in the horizontal part of the mounting carrier 1, and the second slide rail 52 is arranged on the left side of the vertical part of the mounting carrier 1.

[0047] Specifically, the first slide rail 51 extends in the front-rear direction, a through hole is formed in the first slide rail 51, the through hole is communicated with the mounting port 2 in the up-down direction, the cover 3 is in sliding cooperation with the first slide rail 51, the cover 3 can slide forward to cover the through hole and the mounting port 2, the cover 3 can slide backward to open the through hole and the mounting port 2, the position where the cover 3 completely covers the mounting port 2 is the closed position, and the position where the cover 3 completely opens the mounting port 2 is the open position; the second slide rail 52 extends in the up-down direction and is communicated with the through hole and the mounting port 2, the charging interface 4 is in sliding cooperation with the second slide rail 52, and the charging interface 4 can slide upward under the pulling force generated by the charger to extend out of the mounting port 2.

[0048] Further, the first slide rail 51 is a groove-shaped member, a sliding groove with its notch facing upward is formed in the groove-shaped member, the cover 3 is in sliding cooperation with the sliding groove, and a through hole is formed in the left end of the lower bottom wall of the groove-shaped member; the second slide rail 52 is a tubular member, a sliding channel penetrating in the up-down direction is formed in the tubular member, the upper end of the tubular member is communicated with the through hole and the mounting port 2, and the charging interface 4 is inserted into the lower end of the sliding channel and exposed outside the lower end of the second slide rail 52, so as to facilitate the electrical connection between the lower end of the charging interface 4 and the charging element.

[0049] Preferably, the slide structure further comprises a connecting part, which integrally connects the lower bottom wall of the first slide rail 51 and the right tubular wall of the second slide rail 52, so as to integrally connect the first slide rail 51 and the second slide rail 52, thereby reducing the number of components of the charging interface device and facilitating the assembly of the charging interface device. Moreover, the connecting part is fixedly installed with the vertical part of the mounting carrier 1, thereby strengthening the connection between the slide structure and the mounting carrier 1.

[0050] As shown in the drawings, Figures 5 to 8 In some embodiments, the cover driving unit comprises a push-pull mechanism 6, which is in driving cooperation with the cover 3, and is arranged on the side of the cover 3 along the opening direction, i.e. at the rear of the cover 3.

[0051] Specifically, the push-pull mechanism 6, i.e. Push-Push mechanism, comprises a locked state and an unlocked state, and the cover 3 includes an opening position, a closing position and a switching position in the process of sliding in the front-rear direction.

[0052] The cover 3 moves from the closed position to the switching position and acts on the push-pull mechanism 6 to switch the push-pull mechanism 6 from the unlocked state to the locked state, realize the connection locking with the cover 3, and thus lock the cover 3 in the open position. When switched from the unlocked state to the locked state, the push-pull mechanism 6 will exert a forward pushing force on the cover 3, so that the cover 3 moves from the switching position back to the open position.

[0053] The cover 3 moves from the open position to the switching position and acts on the push-pull mechanism 6 to switch the push-pull mechanism 6 from the locked state to the unlocked state, realize the disconnection locking with the cover 3, and when switched from the locked state to the unlocked state, the push-pull mechanism 6 will exert a forward pushing force on the cover 3, so that the cover 3 moves from the switching position back to the closed position.

[0054] The push-pull mechanism 6 is internally provided with an elastic reset member. When the push-pull mechanism 6 is switched from the unlocked state to the locked state, the elastic reset member will be compressed by the cover 3. After being switched from the locked state to the unlocked state, the elastic reset member will exert a forward pushing force on the cover 3. The elastic reset member can be a spring, a torsion spring, rubber or other elastic member.

[0055] Further, the cover driving unit further comprises a transmission assembly 7 which is in transmission connection with the charging interface member 4 and the cover 3. The upward movement of the charging interface member 4 when the charger is pulled out of the charging interface member 4 is a driving action. The occurrence of the driving action is converted by the transmission assembly 7 into an opening action force exerted on the cover 3 in the opening direction, i.e. pushing the cover 3 to move backward to switch the push-pull mechanism 6 from the locked state to the unlocked state.

[0056] It should be noted that the specific structure of the push-pull mechanism 6 is well known to those skilled in the art and does not belong to the core of the present application. Therefore, it will not be described here. The push-pull mechanism 6 can be a common push-pull lock, and a lock tongue structure corresponding to the push-pull lock is provided on the cover 3.

[0057] In addition to using the push-pull mechanism 6 to lock and unlock the cover 3, a movable bolt and a spring can also be used. Specifically, the cover 3 moves backward to continuously compress the spring until it reaches the open position. The movable bolt automatically falls into the bolt hole on the cover 3 to fix the cover 3 in the open position. The movable bolt is in transmission connection with the charging interface member 4 through the transmission assembly 7. When the charging interface member 4 moves upward, the movable bolt is separated from the bolt hole to separate from the cover 3. At this time, the spring is elongated to push the cover 3 back to the closed position. Those skilled in the art can understand that in addition to the above two ways, other mechanisms that can be in transmission connection with the charging interface member 4 and can realize the reset of the cover 3 can also be used.

[0058] Preferably, the cover driving unit further comprises an elastic extension member 8, which can exert a downward force on the charging interface member 4 to reset after the charging interface member 4 is moved upward out of the installation opening 2, so as to avoid interference with the sliding of the cover 3 to the closed position, thereby improving the reliability of the charging interface device. The elastic extension member 8 can be a spring, rubber or other elastic component.

[0059] Specifically, the elastic extension member 8 is arranged in the installation carrier 1 and extends along the extension direction of the second sliding rail 52, the front side wall of the second sliding rail 52 is provided with an upper connecting plate 9, the front side wall of the lower end of the charging interface member 4 is provided with a lower connecting plate 10, the upper connecting plate 9 and the lower connecting plate 10 are arranged in parallel and spaced apart in the up-down direction, the upper end of the elastic extension member 8 is fixedly connected to the upper connecting plate 9, and the lower end of the elastic extension member 8 is fixedly connected to the lower connecting plate 10.

[0060] Further, the charging interface member 4 includes an initial position, an upward terminal position and a downward terminal position in the process of sliding in the up-down direction, the upward terminal position is the highest position reached by the charging interface member 4 being lifted by the charger, and the downward terminal position is the lowest position reached by the charging interface member 4 being pressed by the charger. The charging interface member 4 is in the initial position, and the elastic extension member 8 is in the original length; in the process of moving the charging interface member 4 from the initial position to the upward terminal position, the lower connecting plate 10 is driven upward by the charging interface member 4 to compress the elastic extension member 8, and after the charging interface member 4 reaches the upward terminal position, the elastic extension member 8 exerts a downward pulling force on the charging interface member 4 to reset; in the process of moving the charging interface member 4 from the initial position to the downward terminal position, the lower connecting plate 10 is driven downward by the charging interface member 4 to lengthen the elastic extension member 8, and after the charging interface member 4 reaches the downward terminal position, the elastic extension member 8 exerts an upward pulling force on the charging interface member 4 to reset.

[0061] In some embodiments, the transmission assembly 7 comprises a first rotating rod 71 and a second rotating rod 72, wherein the first rotating rod 71 is in transmission connection with the charging interface member 4, the second rotating rod 72 is in transmission connection with the cover 3, and the first rotating rod 71 and the second rotating rod 72 are in transmission connection. The upward sliding of the charging interface member 4 drives the first rotating rod 71 to rotate, the rotation of the first rotating rod 71 drives the second rotating rod 72 to rotate, and the rotation of the second rotating rod 72 drives the cover 3 to slide backward.

[0062] Specifically, the first rotating rod 71 comprises a first disc part 711 and a first connecting rod part 712 extending along the radial direction of the first disc part 711, and the second rotating rod 72 comprises a second disc part 721 and a second connecting rod part 722 extending along the radial direction of the second disc part 721; the diameter of the first disc part 711 is the same as the diameter of the second disc part 721, the first disc part 711 and the second disc part 721 are coaxial and arranged in parallel and spaced apart along the axial direction, and the second disc part 721 is located between the first disc part 711 and the vertical part of the mounting carrier 1 along the axial direction; the second disc part 721 is provided with an arc-shaped hole 723 extending along the rotation direction of the second disc part 721; the transmission assembly 7 further comprises a first pivot rod 73 and a second pivot rod 74 arranged in parallel and spaced apart, the axial length of the first pivot rod 73 is greater than the axial length of the second pivot rod 74, one end of the first pivot rod 73 and the second pivot rod 74 is fixedly connected with the mounting carrier 1, the other end of the second pivot rod 74 is pivotally connected with the second disc part 721, the central axis of the second pivot rod 74 coincides with the central axis of the second disc part 721, and the other end of the first pivot rod 73 passes through the arc-shaped hole 723 and is pivotally connected with the first disc part 711.

[0063] During the rotation of the second disc part 721, the arc-shaped hole 723 slides relative to the first pivot rod 73, thereby avoiding the interference of the rotation of the second disc part 721 by the first pivot rod 73; the first connecting rod part 712 is in transmission connection with the charging interface 4, and the second connecting rod part 722 is in transmission connection with the cover 3; the first disc part 711 is provided with a first stop point protrusion 713, and the second disc part 721 is provided with a second stop point protrusion 724, the second stop point protrusion 724 and the first stop point protrusion 713 are located at the axial end faces of the second disc part 721 and the first disc part 711, respectively; the first stop point protrusion 713 and the second stop point protrusion 724 extend along the axial direction and towards each other, and the sum of the axial length of the first stop point protrusion 713 and the axial length of the second stop point protrusion 724 is greater than the axial spacing between the first disc part 711 and the second disc part 721.

[0064] Further, the axial direction of the first disc part 711 and the second disc part 721 is the left-right direction, the first disc part 711 is located at the left side of the second disc part 721, and the second disc part 721 is located at the left side of the vertical part of the mounting carrier 1. The transmission assembly 7 further comprises a first pivot rod 73 and a second pivot rod 74, both of which extend along the left-right direction, and the first pivot rod 73 and the second pivot rod 74 are arranged in the front-rear direction, the axial length of the first pivot rod 73 is greater than the axial length of the second pivot rod 74; the right end of the first pivot rod 73 and the right end of the second pivot rod 74 are connected with the connecting part of the slide structure 5, the left end of the second pivot rod 74 is pivotally connected with the second disc part 721, and the center axis of the second pivot rod 74 coincides with the center axis of the second disc part 721, and the left end of the first pivot rod 73 passes through the arc-shaped hole 723 and is pivotally connected with the first disc part 711.

[0065] The specific working principle of the transmission assembly 7 is described below:

[0066] As shown in Figure 5 and Figure 6 , the cover closing state of the transmission assembly 7 corresponds to the charging interface 4 being located at the initial position and the cover 3 being located at the cover closing position, and the cover closing state: the first connecting rod part 712, the first disc part 711, the first stop point protrusion 713, the second connecting rod part 722, the second disc part 721 and the second stop point protrusion 724 are all located at the starting position;

[0067] As shown in Figure 7 and Figure 8 , the cover opening state of the transmission assembly 7 corresponds to the charging interface 4 being located at the initial position and the cover 3 being located at the cover opening position, and the cover opening state: the first connecting rod part 712, the first disc part 711 and the first stop point protrusion 713 are all located at the starting position; the second connecting rod part 722, the second disc part 721 and the second stop point protrusion 724 are all located at the terminal position;

[0068] The driving state of the transmission assembly 7 corresponds to the charging interface 4 being located at the upward terminal position and the cover 3 being located at the switching position, and the driving state: the first connecting rod part 712, the first disc part 711 and the first stop point protrusion 713 are all located at the terminal position; the second connecting rod part 722, the second disc part 721 and the second stop point protrusion 724 are all located at the driving position;

[0069] The movement path of the first stop point protrusion 713 from the initial position to the end position and then to the driving position is a first circular arc with the center of the first pivot rod 73 as the center, and the movement path of the second stop point protrusion 724 from the initial position to the end position is a second circular arc with the center of the second pivot rod 74 as the center. The orthogonal projection of the first circular arc in the plane of the first disc part 711 and the orthogonal projection of the second circular arc in the plane of the first disc part 711 have intersection points. In other words, when the second stop point protrusion 724 is in the end position, the first stop point protrusion 713 can collide with the second stop point protrusion 724 during the rotation from the initial position to the end position and apply a pushing force to make the second stop point protrusion 724 move from the end position to the driving position, thereby driving the cover 3 to slide from the cover opening position to the switching position.

[0070] In fact, the first stop point protrusion 713 and the second stop point protrusion 724 are not a point, but have a certain size, so as to better realize the collision of the first stop point protrusion 713 and the second stop point protrusion 724, thereby improving the reliability of the charging interface device.

[0071] Preferably, the first stop point protrusion 713 extends along the first radial direction of the first disc part 711 and includes a first radial far end and a first radial near end. The radial distance between the first radial far end and the center of the first disc part 711 is greater than the radial distance between the first radial near end and the center of the first disc part 711. The second stop point protrusion 724 extends along the second radial direction of the second disc part 721 and includes a second radial far end and a second radial near end. The radial distance between the second radial far end and the center of the second disc part 721 is greater than the radial distance between the second radial near end and the center of the second disc part 721. The radial distance between the first radial far end and the center of the first disc part 711 is less than the radial distance between the second radial far end and the center of the second disc part 721.

[0072] When the transmission assembly 7 switches from the cover closing state to the cover opening state, the first rotating rod 71 is stationary, the second rotating rod 72 rotates around the second pivot rod 74, and the second stop point protrusion 724 rotates from one side to the other side along the circumference of the first stop point protrusion 713. When the transmission assembly 7 switches from the cover opening state to the driving state, the first rotating rod 71 rotates around the first pivot rod 73, the second rotating rod 72 is stationary, the first stop point protrusion 713 rotates close to the second stop point protrusion 724 and pushes the second stop point protrusion 724 to rotate from the end position to the switching position.

[0073] Preferably, the transmission assembly 7 further comprises a torsional elastic member 75, the extension direction of the torsional elastic member 75 is along the circumference of the second disc part 721, one end of the torsional elastic member 75 is fixed, and the other end is connected with the second disc part 721. The lower part of the cover 3 is provided with a protruding part 31 which abuts against the second connecting rod part 722 and is located behind the second connecting rod part 722.

[0074] Specifically, the torsional elastic member 75 is a torsion spring, one end of the torsion spring is fixedly connected with the connecting part, the other end of the torsion spring is insertedly matched with the second disc part 721, and the second connecting rod part 722 is abuttingly matched with the cover. During the process that the cover 3 moves forward from the open cover position to the closed cover position, the protruding part 31 of the cover 3 pushes the second connecting rod part 722 forward to compress the torsional elastic member 75, and during the process that the cover 3 moves backward from the closed cover position to the open cover position, the torsional elastic member 75 pushes the second disc part 721 to rotate to make the second connecting rod part 722 move backward with the cover 3 and continuously abut.

[0075] Further, the upper portion of the cover 3 is provided with a pushing part 32, and the pushing part 32 is used for manually pushing the cover 3.
