[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] It should be noted that all directional indications in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0049] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] In the related art, there is a technical problem that the cover is not tightly sealed. The embodiment of the present application provides a charging cover assembly and a vehicle, which can at least solve the technical problem of the cover not being tightly sealed to a certain extent.

[0052] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0053] like Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 6 and Figure 7 As shown, the charging port cover assembly 100 includes a cover 110 , a base 120 , a connecting rod assembly 130 , a driving assembly 150 and at least two locking assemblies 140 .

[0054] The base 120 has a charging hole 120a for avoiding the charging interface.

[0055] When the charging port cover assembly 100 is used, the base 120 is fixedly connected to the vehicle body. The charging interface is an interface for electrically connecting to the charging gun when the vehicle is charging. The charging interface is exposed to the outside through the charging via 120a. When charging is required, the user plugs the charging gun into the charging interface to charge the vehicle. The structure of the charging interface is known to those skilled in the art, and its structure is diverse and is not limited in this application. The size and shape of the charging via 120a are related to the size and shape of the charging interface. The user can adaptively design the charging via 120a according to the charging interface, which is not limited in this application. In some embodiments, the base 120 includes a base body 122 and a base cover 123, the base cover 123 is detachably connected to the base body 122, and the base cover 123 and the base body 122 are enclosed to form an installation cavity, and the drive assembly 150 is disposed in the installation cavity.

[0056] The connecting rod assembly 130 is rotatably connected to both the cover 110 and the base 120 .

[0057] One side of the connecting rod assembly 130 is rotatably connected to the cover 110, and the other side is rotatably connected to the base 120. When the connecting rod assembly 130 rotates, the connecting rod assembly 130 can drive the cover 110 to rotate, so that the cover 110 moves relative to the base 120, and the cover 110 can switch between a closed state that shields the charging hole 120a and an open state that opens the charging hole 120a.

[0058] When the cover 110 is in the closed state, the cover 110 shields the charging interface to prevent the charging interface from being exposed to the outside and causing damage. When the cover 110 is in the open state, the inner charging interface is exposed to facilitate the user to insert the charging gun into the charging interface to charge the vehicle. It is easy to understand that in the closed state, the cover 110 can completely shield the base 120 to shield the charging interface, and in the closed state, the cover 110 can contact the base 120 and fit tightly to prevent external rain, dust, etc. from entering the base 120 through the gap between the cover 110 and the base 120, causing damage to the charging interface, etc.

[0059] The locking assembly 140 is mounted on the base 120 , and at least two locking assemblies 140 are spaced apart in the X direction and / or the Z direction.

[0060] At least two locking assemblies 140 are provided, and the locking assemblies 140 are movably mounted on the base 120, so that the locking assemblies 140 can move relative to the base 120, so that the locking assemblies 140 have a locked state in which they are connected to the cover 110 to lock the cover 110, and an unlocked state in which they are separated from the cover 110 to unlock the cover 110. The at least two locking assemblies 140 can be spaced apart in the X direction, can be spaced apart in the Z direction, or can be spaced apart in both the X direction and the Z direction.

[0061] The driving assembly 150 is installed on the base 120, and is used to drive the connecting rod assembly 130 and the locking assembly 140 to move, so that the cover 110 switches between a covered state covering the charging hole 120a and an open state opening the charging hole 120a, and switches at least two locking assemblies 140 between a locked state in which both are connected to the cover 110 to lock the cover 110 and an unlocked state in which both are separated from the cover 110 to unlock the cover 110; wherein, when the cover 110 is in the open state, the locking assembly 140 is in the unlocked state, and when the cover 110 is in the covered state, the locking assembly 140 is in the locked state.

[0062] The driving assembly 150 drives the connecting rod assembly 130 to move, and drives the multiple locking assemblies 140 to move. When the driving assembly 150 drives the connecting rod assembly 130, the connecting rod assembly 130 can drive the mouth cover 110 to move, so that the mouth cover 110 moves relative to the base 120, and then the mouth cover 110 can be in a closed state or in an open state. When the driving assembly 150 drives the locking assembly 140, the locking assembly 140 can move relative to the mouth cover 110, and then the locking assembly 140 can be in a locked state connected to the mouth cover 110 or an unlocked state separated from the mouth cover 110.

[0063] It is easy to understand that when the cover 110 is in the closed state, the locking assembly 140 is in the locked state and connected to the cover 110, locking the cover 110 to ensure that the cover 110 remains in the closed state and will not be opened due to vibration during the driving process of the vehicle. When the cover 110 is in the open state, the locking assembly 140 is in the unlocked state and separated from the cover 110 to ensure that the cover 110 can be opened smoothly under the action of the driving assembly 150. In other words, the locking assembly 140 locks the cover 110 after the cover 110 is closed, and the cover 110 is opened under the action of the driving assembly 150 after the locking assembly 140 is unlocked.

[0064] The charging port cover assembly 100 ensures the stability of the cover 110 in the locked state by distributing multiple locking components 140 in the X direction and / or the Z direction at intervals, which helps to reduce the amount of warping of the cover 110 in the locked state, so that the cover 110 fits tightly on the base 120, thereby ensuring the sealing performance between the cover 110 and the base 120, reducing the impact of external rain, dust, etc. on the inner wall charging interface, thereby improving the safety of the charging interface. The charging port cover assembly 100 drives the connecting rod assembly 130 and multiple locking components 140 to move at the same time through the driving component 150, which simplifies the structure of the charging port cover assembly 100 and helps to reduce the production cost of the charging port cover assembly 100.

[0065] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the driving assembly 150 includes a driving element 151, a first transmission unit 152, a first output member 153, and a second transmission unit 155. The driving element 151 is mounted on the base 120; the first fixed end 1521 of the first transmission unit 152 is connected to the output end of the driving element 151, and the driving element 151 drives the first transmission unit 152 to rotate; the first output member 153 is slidably connected to the base 120, and is power-coupled with the first free end 1522 of the first transmission unit 152, so that when the first transmission unit 152 rotates around the first rotation direction, it slides along the first direction to drive the locking assembly 140 to move; the second transmission unit 155 is rotatably connected to the base 120, and is rotatably connected to the second free end 1523 of the first transmission unit 152, so that when the first transmission unit 152 rotates around the second rotation direction, it drives the connecting rod assembly 130 to move, and the first rotation direction and the second rotation direction are opposite.

[0066] The driving element 151 outputs torque or outputs rotational power. The driving element 151 can be a motor, etc. The output end of the driving element 151 is used to be connected to the first fixed end 1521 of the first transmission unit 152 to drive the first transmission unit 152 to rotate. When the first transmission unit 152 rotates around the first rotation direction, the first free end 1522 of the first transmission unit 152 will drive the first output member 153 to slide along the first direction, so that the first output member 153 drives the locking assembly 140 to move, so that the locking assembly 140 unlocks the cover 110 or locks the cover 110. When the first transmission unit 152 rotates around the second rotation direction, the second free end 1522 of the first transmission unit 152 will drive the second transmission unit 155 to rotate around the base 120, so that the cover 110 moves, so that the cover 110 covers the charging hole 120a or opens the charging hole 120a.

[0067] In some embodiments, the driving assembly 150 also includes a reset member 154, which acts on the base 120 and the first output member 153, and is used to drive the first output member 153 to slide along the second direction during the rotation of the first transmission unit 152 around the second rotation direction, and the first direction and the second direction are opposite.

[0068] One side of the reset member 154 acts on the base 120, and the other side acts on the first output member 153. The reset member 154 is used to reset the first output member 153. Specifically, during the rotation of the first transmission unit 152 around a second rotation direction opposite to the first rotation direction, the first transmission unit 152 will not drive the first output member 153 to continue to slide along the first direction. The first output member 153 will slide along the second direction opposite to the first direction under the action of the reset member 154, so that the first output member 153 is reset to the position before being driven by the first output member 153, thereby driving the locking assembly 140 to reset to unlock the cover 110 or lock the cover 110.

[0069] The reset member 154 may be an elastic member, such as a spring, a torsion spring, etc., which is not limited in the present application. The first output member 153 may move in the second direction or the first direction under the drive of the reset member 154 and the first transmission unit 152, thereby driving the locking assembly 140 to unlock the cover 110 or lock the cover 110. The first transmission unit 152 only participates in one of the unlocking process and the locking process of the locking assembly 140, and the other of the unlocking process and the locking process is realized by the reset member 154. Such a design simplifies the function of the first transmission unit 152, helps to reduce the structural difficulty of the first transmission unit 152, and facilitates the processing of the first transmission unit 152. Moreover, such a design can facilitate the first transmission unit 152 to drive the connecting rod assembly 130 to move at the same time, helps to realize the sequence of first unlocking the cover 110 and then opening the cover 110, and ensures that the cover 110 can be smoothly unlocked and opened, and helps to realize the sequence of first closing the cover 110 and then locking the cover 110, and ensures that the cover 110 can be smoothly closed and locked.

[0070] If the first transmission unit 152 drives the locking assembly 140 to unlock the cover 110 , the reset member 154 drives the locking assembly 140 to lock the cover 110 ; if the first transmission unit 152 drives the locking assembly 140 to lock the cover 110 , the reset member 154 drives the locking assembly 140 to unlock the cover 110 .

[0071] In some embodiments, along the first rotation direction, at least a portion of the first output member 153 is located in front of the first free end 1522 , so that the first output member 153 can slide along the first direction under the push of the first transmission unit 152 .

[0072] Along the first rotation direction of the first transmission unit 152, at least a portion of the first output member 153 is located at the front side of the first free end 1522, so that after the first transmission unit 152 rotates a certain angle along the first rotation direction, it can contact the first output member 153, push the first output member 153 to slide along the first direction, and then the first output member 153 drives the locking assembly 140 to move to unlock the cover 110 or lock the cover 110.

[0073] In some embodiments, when the driving element 151 drives the first transmission unit 152 to rotate around the first rotation direction, the first free end 1522 of the first transmission unit 152 will abut against the first output member 153, and drive the first output member 153 to rotate along the first direction, thereby driving the locking assembly 140 to move, so that the locking assembly 140 is connected to the cover 110 to lock the cover 110. When the driving element 151 drives the first transmission unit 152 to rotate around the second rotation direction, the first output member 153 will slide along the second direction driven by the reset member 154, thereby driving the locking assembly 140 to move, so that the locking assembly 140 is separated from the cover 110 to unlock the cover 110.

[0074] In some embodiments, the reset member 154 is a spring. When the first transmission unit 152 drives the first output member 153 to slide in the first direction, the locking assembly 140 locks the cover 110; when the reset member 154 drives the first output member 153 to slide in the second direction, the locking assembly 140 unlocks the cover 110.

[0075] In these embodiments, under the condition that the first transmission unit 152 rotates around the first rotation direction and contacts the first output member 153, the first transmission unit 152 drives the first output member 153 to slide along the first direction, and the first output member 153 drives the locking assembly 140 to move, so that the locking assembly 140 is connected to the cover 110, and then the cover 110 is locked. In this process, the elastic member is deformed and gradually accumulates energy; under the condition that the first transmission unit 152 rotates around the second rotation direction, the force applied by the reset member 154 to the first transmission unit 152 drives the first output member 153 to slide along the second direction, and the first output member 153 drives the locking assembly 140 to move in the opposite direction, so that the locking assembly 140 is separated from the cover, and then the cover 110 is unlocked.

[0076] In some embodiments, the second transmission unit 155 includes a first connecting rod 1551 and a second connecting rod 1552. The third free end 15511 of the first connecting rod 1551 is rotatably connected to the second free end 1523 of the first transmission unit 152, and the second free end 1523 is disposed between the first fixed end 1521 and the first free end 1522. The fourth free end 15521 of the second connecting rod 1552 is rotatably connected to the fifth free end 15512 of the first connecting rod 1551, and the second fixed end 15522 of the second connecting rod 1552 is rotatably connected to the base and fixedly connected to the connecting rod assembly 130.

[0077] It should be noted that the first fixed end 1521 and the first free end 1522 of the first transmission unit 152 are arranged at intervals, and the second free end 1523 of the first transmission unit 152 is arranged between the first fixed end 1521 and the first free end 1522. With this design, the rotation of the first transmission unit 152 will drive the first connecting rod 1551 to rotate, the rotation of the first connecting rod 1551 will drive the second connecting rod 1552 to rotate, and the rotation of the second connecting rod 1552 will drive the connecting rod assembly 130 to rotate, thereby driving the mouth cover 110 to move, so that the mouth cover 110 is in a closed state or an open state. The connecting rod assembly 130 and the second connecting rod 1552 rotate synchronously, that is, the connecting rod assembly 130 rotates when the second connecting rod 1552 rotates, and the connecting rod assembly 130 does not rotate if the second connecting rod 1552 does not rotate.

[0078] Since the first fixed end 1521 and the second fixed end 15522 only rotate and do not move, the distance between the first fixed end 1521 and the second fixed end 15522 is unchanged, and the third free end 15511 of the first connecting rod 1551 will, under the action of the first transmission unit 152, make a circular motion with the second free end 1523 as the center and the distance between the second free end 1523 and the first fixed end 1521 as the radius. In this way, the second connecting rod 1552 does not rotate when the first connecting rod 1551 rotates, and the first connecting rod 1551 and the second connecting rod 1552 can rotate together.

[0079] That is to say, due to the mutual cooperation between the first link 1551, the second link 1552 and the first transmission unit 152, the first link 1551 and the second link 1552 are configured such that: before the locking assembly 140 is in the unlocked state, when the first transmission unit 152 rotates along the second rotation direction, the first link 1551 rotates following the first transmission unit 152, but the second link 1552 does not rotate; after the locking assembly 140 is in the unlocked state, when the first transmission unit 152 rotates along the second rotation direction, the first link 1551 and the second link 1552 rotate. 552 both rotate with the first transmission unit 152 so that the cover 110 opens the charging hole 120a; before the cover 110 is in the covering state, when the first transmission unit 152 rotates along the first rotation direction, the first connecting rod 1551 and the third connecting rod both rotate with the first transmission unit 152 so that the cover 110 covers the charging hole 120a; after the cover 110 is in the covering state, when the first transmission unit 152 rotates along the first rotation direction, the first connecting rod 1551 rotates with the first transmission unit 152, but the second connecting rod 1552 does not rotate.

[0080] When the first transmission unit 152 rotates around the second rotation direction, driving the first connecting rod 1551 to rotate, but the second connecting rod 1552 does not rotate, the connecting rod assembly 130 does not rotate, and the cover 110 does not move. At this time, the reset member 154 drives the first output member 153 to move, and then drives the locking assembly 140 to move to unlock the cover 110; and when the cover 110 is unlocked, the second connecting rod 1552 will rotate with the first connecting rod 1551, thereby driving the cover 110 to move, so that the cover 110 is opened. The function of the cover 110 not moving before the cover 110 is unlocked is realized, and the cover 110 is prevented from interfering when the locking assembly 140 is unlocked.

[0081] When the first transmission unit 152 rotates around the first direction, driving the first connecting rod 1551 and the second connecting rod 1552 to rotate together, the mouth cover 110 moves and gradually closes. At this time, the first transmission unit 152 is not in contact with the first output member 153, and the locking assembly 140 is in an unlocked state; when the mouth cover 110 is in the closed state, the first transmission unit 152 continues to rotate around the first direction, driving the first connecting rod 1551 to rotate, and the second connecting rod 1552 will not continue to rotate. The first transmission unit 152 drives the first output member 153 to rotate along the first direction, thereby driving the locking assembly 140 to lock the mouth cover 110, realizing the function that before the mouth cover 110 is closed, the locking assembly 140 does not act, and after the mouth cover 110 is closed, the locking assembly 140 acts again to lock the mouth cover 110.

[0082] In some embodiments, when the cover 110 is to be opened, the first transmission unit 152 rotates in the second rotation direction. When the first transmission unit 152 rotates 17° in the second rotation direction, the locking assembly 140 is separated from the cover 110, and the locking assembly 140 is in an unlocked state. After the first transmission unit 152 rotates more than 17° in the second rotation direction, the second connecting rod 1552 rotates following the first connecting rod 1551, so that the cover 110 gradually opens. When it rotates to 137°, the cover 110 is fully opened and in an open state.

[0083] In some embodiments, when the cover 110 is in the closed state, the line connecting the fourth free end 15521 and the second fixed end 15522 forms an acute angle with the line connecting the first fixed end 1521 and the second fixed end 15522. When the cover 110 is in the open state, the line connecting the fourth free end 15521 and the second fixed end 15522 forms an obtuse angle with the line connecting the first fixed end 1521 and the second fixed end 15522.

[0084] like Fig.10 As shown, in some embodiments, the connecting rod assembly 130 includes an active connecting rod 131 and a driven connecting rod 132, one side of the active connecting rod 131 is rotatably connected to the mouth cover 110, and the other side is fixedly connected to the second fixed end 15522 of the second connecting rod 1552; one side of the driven connecting rod 132 is rotatably connected to the mouth cover 110, and the other side is also rotatably connected to the base 120.

[0085] The active link 131 is fixedly connected to the second fixed end 15522, so the active link 131 can rotate with the second link 1552, thereby driving the mouth cover 110 to rotate, and the driven link 132 moves with the movement of the mouth cover 110. The setting of the driven link 132 ensures the stability of the movement of the mouth cover 110. In order to ensure the stability of the rotation of the active link 131, the side of the active link 131 fixedly connected to the second fixed end 15522 can also be rotatably connected to the base 120. The number of active links 131 and driven links 132 can be one or more, which is not limited in this application.

[0086] The locking components 140 may be provided in two, three, four, etc., which is not limited in the present application. When multiple locking components 140 are provided, the structures of the locking components 140 may be different or the same.

[0087] like Figure 5 and Figure 6As shown, in some embodiments, two locking assemblies 140 are provided, wherein one locking assembly 140 is connected to the mouth cover 110 by rotation, and the other locking assembly 140 is connected to the mouth cover by translation; both locking assemblies 140 are provided beside one side where the active connecting rod 131 is rotationally connected to the mouth cover 110, and the two locking assemblies 140 are spaced apart in the Z direction.

[0088] like Figure 6 As shown, that is, when the mouth cover 110 is in the closed state, the two locking assemblies 140 are both located near the side where the active connecting rod 131 is rotatably connected to the mouth cover 110, and the two locking assemblies 140 are both connected to the area where the mouth cover 110 is rotatably connected to the active connecting rod. And one of the locking assemblies 140 is arranged in the upper area, and the other locking assembly 140 is arranged in the lower area.

[0089] The active link 131 rotates to drive the flap 110 to move, and the flap 110 drives the driven link 132 to rotate. Therefore, the movement of the active link 131 determines whether the flap 110 moves. The stability of the position of the area where the flap 110 and the active link 131 are rotatably connected affects the overall stability of the flap 110 and the warping amount of the flap 110 to a certain extent. In these embodiments, the locking components 140 are arranged in an upper and lower interval, and are arranged on the side where the active link 131 and the flap 110 are rotatably connected, which ensures the stability and accuracy of the area where the flap 110 and the active link 131 are rotatably connected when the flap 110 is closed, helps to reduce the warping amount of the flap 110 when the flap 110 is closed, and ensures that the flap 110 is tightly closed.

[0090] The locking assembly 140 is connected to the mouth cover 110 in a translational manner, which means that the part of the locking assembly 140 connected to the mouth cover 110 is connected to the mouth cover 110 in a translational manner. The locking assembly 140 is connected to the mouth cover 110 in a rotational manner, which means that the part of the locking assembly 140 connected to the mouth cover 110 is connected to the mouth cover 110 in a rotational manner. The two locking assemblies 140 are connected to the mouth cover 110 in different movement modes, which can form a firm lock on the mouth cover 110 and improve the stability of the mouth cover 110 in the closed state.

[0091] like Figure 5As shown, in some embodiments, the locking assembly 140 connected to the cover 110 in a rotational manner may include a first gear 141, a first rotating shaft 142, and a first locking tongue 143. The first gear 141 and the first locking tongue 143 are both fixedly connected to the first rotating shaft 142, the first rotating shaft 142 is rotatably connected to the base 120, the first output member 153 includes a first rack portion 1531, and the first gear 141 is meshed with the first rack portion 1531; the cover 110 is provided with a first slot 110a, and in the locked state, the first locking tongue 143 is located in the first slot 110a.

[0092] The first gear 141 and the first locking tongue 143 are both fixed on the first rotating shaft 142, and the first rotating shaft 142 is rotatably connected to the base 120, so the first gear 141, the first locking tongue 143 and the first rotating shaft 142 rotate synchronously. The first output member 153 has a first rack portion 1531, and the first rack portion 1531 is meshed with the first gear 141 to form a gear rack structure. When the first output member 153 slides along the first direction or the second direction, it drives the first gear 141 to rotate toward the first slot 110a or away from the first slot 110a, so that the locking tongue is located in the first slot 110a to connect with the cover 110 to lock the cover 110, or the locking tongue is located outside the first slot 110a to separate from the cover 110 to unlock the cover 110.

[0093] In some embodiments, when the first output member 153 slides along the first direction driven by the first transmission unit 152, the first output member 153 drives the first locking tongue 143 to rotate toward the first slot 110a, so that the first locking tongue 143 is located in the first slot 110a; when the first output member 153 slides along the second direction under the action of the reset member 154, the first output member 153 drives the first locking tongue 143 to rotate in the direction away from the first slot 110a, so that the first locking tongue 143 is located outside the first slot 110a.

[0094] The structures of the first locking tongue 143 and the first locking slot 110 a are various and are not limited in the present application.

[0095] like Figure 6As shown, in some embodiments, the locking assembly 140 connected to the cover 110 in a translational manner may include a second gear 145, a second rotating shaft 146, a third gear 147, and a second locking tongue 148. The second gear 145 and the third gear 147 are respectively fixed to the two sides of the second rotating shaft 146, the second rotating shaft 146 is rotatably connected to the base 120, the first output member 153 also includes a second rack portion 1532 fixedly connected to the first rack portion 1531, and the second gear 145 is meshed with the second rack portion 1532; the second locking tongue 148 has a third rack portion 1481, and the second locking tongue 148 is slidably connected to the base 120, and the third gear 147 is meshed with the third rack portion 1481; the cover 110 has a second slot 110b, and in the locked state, the second locking tongue 148 is located in the second slot 110b.

[0096] The second gear 145 and the third gear 147 are respectively fixed to the two sides of the second rotating shaft 146, so the second gear 145, the third gear 147 and the second rotating shaft 146 rotate synchronously. The second rack portion 1532 of the first output member 153 meshes with the second gear 145, so that a gear rack structure is formed between the second rack portion 1532 and the second gear 145. When the first output member 153 slides along the first direction or the second direction, it drives the second gear 145 to rotate clockwise or counterclockwise, thereby driving the third gear 147 to rotate. The second locking tongue 148 has a third rack portion 1481, and the third rack portion 1481 is meshed with the third gear 147 to form a gear rack structure. Therefore, when the third gear 147 rotates, it drives the second locking tongue 148 to slide. Specifically, it drives the second locking tongue 148 to move toward the second card slot 110b so that the second locking tongue 148 is located in the second card slot 110b to lock the cover 110, or drives the second locking tongue 148 to move in a direction away from the second card slot 110b so that the second locking tongue 148 is located outside the second card slot 110b to unlock the cover 110.

[0097] In some embodiments, when the first output member 153 slides along the first direction driven by the first transmission unit 152, the first output member 153 drives the second locking tongue 148 to move toward the second slot 110b, so that the second locking tongue 148 is located in the second slot 110b; when the first output member 153 slides along the second direction under the action of the reset member 154, the first output member 153 drives the second locking tongue 148 to rotate in the direction away from the second slot 110b, so that the second locking tongue 148 is gradually located outside the second slot 110b.

[0098] like Figure 5In some of the illustrated embodiments, the first output member 153 also includes a J-shaped resisting portion 1533 fixedly connected to the second rack portion 1532, the first rack portion 1531 and the second rack portion 1532 are arranged back to back, and along the first direction, the first rack portion 1531, the second rack portion 1532 and the resisting portion 1533 are arranged in sequence, and during the rotation of the first transmission unit 152 around the first rotation direction, the first free end 1522 can be located in the resisting portion 1533 and contact the resisting portion 1533.

[0099] The first rack portion 1531 and the second rack portion 1532 are disposed opposite to each other, that is, the first rack portion 1531 faces opposite directions. Figure 5 As shown, in some embodiments, the first rack portion 1531 is arranged toward the side close to the mouth cover 110, and the second rack portion 1532 is arranged toward the side away from the mouth cover 110. The first rack portion 1531 and the second rack portion 1532 are arranged opposite to each other, so that the second gear 145 and the first gear 141 are located on both sides of the first output member 153, which can avoid interference between the second gear 145 and the first gear 141, and ensure the stable operation of the second gear 145 and the first gear 141. The blocking portion 1533 is J-shaped. When the first transmission unit 152 rotates around the first rotation direction, the first free end 1522 can rotate into the blocking portion 1533 and abut against the blocking portion 1533, thereby driving the first output member 153 to slide along the first direction. When the first transmission unit 152 rotates around the second rotation direction, the first free end 1522 can rotate out of the blocking portion 1533 and be located outside the blocking portion 1533, thereby ensuring that the reset member 154 drives the first output member 153 to slide along the second direction.

[0100] like Figure 5 , Fig. 9 and Fig.11 As shown, in some embodiments, the first transmission unit 152 has a first abutment portion 1524 and a second abutment portion 1525, the base 120 is provided with a base abutment portion 121, and the charging port cover assembly 100 also includes a limit member 160, which is installed on the base 120. In the open state, the first abutment portion 1524 contacts the base abutment portion 121, and in the closed state, 1522 contacts the limit member 160.

[0101] When the first transmission unit 152 rotates along the second rotation direction until the first abutting portion 1524 contacts the base abutting portion 121 , the cover 110 is in an open state, and the first transmission unit 152 cannot continue to rotate along the second rotation direction due to the abutment of the base abutting portion 121 .

[0102] When the first transmission unit 152 rotates along the first rotation direction until the second abutting portion 1525 contacts the limiting member 160 , the cover 110 is in a closed state, and the first transmission unit 152 cannot continue to rotate along the first rotation direction due to the abutment of the limiting member 160 .

[0103] The working principle of the charging port cover assembly 100 is introduced as follows:

[0104] If the cover 110 is opened: the driving element 151 drives the first transmission unit 152 to rotate along the second rotation direction, the first transmission unit 152 drives the first connecting rod 1551 to rotate, but the second connecting rod 1552 does not rotate, and the first output member 153 will move along the second direction under the action of the restoring force of the reset member 154. When the first output member 153 moves along the second direction, it drives the first gear 141 and the second gear 145 to rotate, thereby driving the first locking tongue 143 to extend out of the first slot 110a, and driving the second locking tongue 148 to extend out of the second slot 110b; as the first transmission unit 152 continues to rotate along the second rotation direction, the first transmission unit 152 not only drives the first connecting rod 1551 to rotate but also drives the second connecting rod 1552 to rotate, thereby driving the active connecting rod 131 to rotate, so that the cover 110 rotates to be opened until the cover 110 is completely opened. After the first abutting portion 1524 contacts the base abutting portion 121 , the first transmission unit 152 cannot continue to rotate along the second rotation direction due to the abutting effect of the base abutting portion 121 .

[0105] If the opening cover 110 is closed: the driving element 151 drives the first transmission unit 152 to rotate along the first rotation direction, the first transmission unit 152 drives the first connecting rod 1551 and the second connecting rod 1552 to rotate, and the second connecting rod 1552 drives the active connecting rod 131 to rotate, thereby driving the opening cover 110 to close; after the opening cover 110 is closed, as the first transmission unit 152 continues to rotate along the first rotation direction, the second connecting rod 1552 will no longer rotate, and the other side of the first transmission unit 152 will contact the first output member 153 and drive the first output member 153 to slide along the first direction, the reset member 154 gradually deforms and stores energy, and the first transmission unit 152 slides along the first direction, which will drive the first gear 141 and the second gear 145 to rotate, so that the first locking tongue 143 extends into the first card slot 110a, and drives the second locking tongue 148 to extend into the second card slot 110b, until the opening cover 110 is locked. After the second abutting portion 1525 contacts the limiting member 160 , the first transmission unit 152 will not be able to continue to rotate along the first rotation direction under the abutting action of the limiting member 160 .

[0106] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, including the above-mentioned charging port cover assembly 100. Since the vehicle includes the above-mentioned charging port cover assembly 100, it naturally has all the beneficial effects of the charging port cover assembly 100, which will not be described in detail here.
