[0045] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application clearer, the present application will be further described in detail below in conjunction with the drawings and a plurality of exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the protection scope of the present application.

[0046] Figure 1 An example of a charging port 1 of a vehicle and a corresponding charging cover device is schematically shown. As Figure 1 shown, the charging port 1 of a vehicle, in particular of an electric vehicle, can have two charging ports, namely a first charging port 11 and a second charging port 12. The first charging port 11 and the second charging port 12 are, for example, a direct current charging port and an alternating current charging port, respectively. The direct current charging port is generally used for direct current fast charging at a dedicated charging station, and the alternating current charging port is, for example, used for alternating current slow charging at a domestic voltage. The first charging port 11 and the second charging port 12 are arranged adjacent to each other. In Figure 1 particular, they are schematically arranged one after the other in a front-rear direction of the vehicle, but it is also conceivable that the first charging port 11 and the second charging port 12 are arranged adjacent to each other in a top-bottom direction or in another direction.

[0047] In order to protect the charging port 1, a charging cover device is provided. The charging cover device comprises an outer cover 2 and an inner cover 3. In order to make the design of the charging port area compact, as Figure 1 shown, there is sometimes one common inner cover 3 for both charging ports. The inner cover 3 is movable between a first position, in which the first charging port 11 of the charging port 1 is covered, and a second position, in which the second charging port 12 of the charging port 1 is covered.

[0048] In the present application, the charging cover device further comprises a linkage mechanism, in the linkage state of which a movement of the opening of the outer cover 2 is transmitted to the inner cover 3 via the linkage mechanism, so that the inner cover 3 is moved from one of the first position and the second position to the other of the first position and the second position. Thereby, the inner cover 3 is opened substantially synchronously with the outer cover 2 and a complex drive for the inner cover 3 is dispensed with.

[0049] According to one exemplary embodiment, the linkage mechanism comprises a first linkage mechanism 41 for moving the inner cover 3 from the first position to the second position and / or a second linkage mechanism 42 for moving the inner cover 3 from the second position to the first position. Here, for the sake of clarity, the first linkage mechanism 41 and the second linkage mechanism 42 are shown separately. That is, Figure 1 and Figure 2 respectively. That is, Figure 1 An example of the first linkage mechanism 41 is schematically shown, Figure 2One example of a second linkage 42 is schematically shown. But it is clear that the charging cover arrangement of the present application can comprise both a first linkage 41 and a second linkage 42 or can comprise only one linkage.

[0050] According to one exemplary embodiment, the linkage comprises a gear transmission, a link transmission, a cam transmission, a traction cable transmission, a chain transmission and / or a belt transmission.

[0051] In Figure 1 and Figure 2 the first linkage 41 and the second linkage 42 are exemplarily a traction cable transmission. As Figure 1 is shown, the first linkage 41 can be used to directly pull the inner cover 3 when the outer cover 2 is opened. As Figure 2 is shown, the second linkage 42 comprises a pulley 421 for diverting a traction cable 422 in order to move the inner cover 3 in the opposite direction.

[0052] Figure 3 Another example of a first linkage 41 is schematically shown. Here, the first linkage 41 is exemplarily a gear transmission. The opening of the outer cover 2 can for example cause an input shaft provided on the outer cover 2 to rotate, the input shaft carrying an input gear 44 which moves the inner cover 3, for example via a transmission gear 45 and / or a rack 47. Figure 4 Another example of a second linkage 42 is schematically shown. Since the second linkage 42 moves the inner cover 3 in the opposite direction, the second linkage 42 here exemplarily comprises one more second transmission gear 46 than the first linkage 41, but can also comprise one less gear. The skilled person can also envisage similar variants, for example the presence of more transmission gears, or the second linkage differs from the first linkage by an odd number of gears.

[0053] According to one exemplary embodiment, the movement of the inner cover 3 between the first position and the second position comprises a pivoting movement and / or a translational movement. In Figure 1 and Figure 2 the movement of the inner cover 3 between the first position and the second position is exemplarily a translational movement. Here, the charging cover arrangement comprises for example a guide rail for the inner cover 3 to translate between the first position and the second position, and the linkage comprises a guide provided on the inner cover 3 for cooperating with the guide rail.

[0054] According to an exemplary embodiment, the first linkage 41 comprises a first guide portion 410, the second linkage 42 comprises a second guide portion 420, the first guide portion 410 and the second guide portion 420 are located at opposite sides of the inner cover 3, the guide rail comprises a first guide rail 51 for the first guide portion 410 and a second guide rail 52 for the second guide portion 420, the first guide portion 410 is configured to slide and / or roll on the first guide rail 51, and the second guide portion 420 is configured to slide and / or roll on the second guide rail 52. The first guide portion 410 and the second guide portion 420 comprise, for example, rollers and / or sliders.

[0055] According to an exemplary embodiment, the opening movement of the outer cover 2 comprises a pivoting movement and / or a translational movement. In Figure 1 and Figure 2 , the opening movement of the outer cover 2 is exemplarily a pivoting movement, for example, as illustrated, the outer cover 2 is flipped open to the right.

[0056] According to an exemplary embodiment, the charging cover device comprises a controller, the controller is configured to receive a position signal and a control signal, and control the linkage according to the position signal and the control signal, the position signal contains information about whether the inner cover 3 is actually in the first position or the second position, and the control signal contains information about whether the inner cover 3 is expected to be in the first position or the second position. For example, if the inner cover 3 is actually in the first position, but is expected to be in the second position, the controller can control the first linkage 41 to be in the linkage state, while the second linkage 42 is in the disengaged state, so that when the outer cover 2 is opened, the inner cover 3 will be moved from the first position to the second position via the first linkage 41. If the inner cover 3 is actually in the second position, but is expected to be in the first position, the opposite is true. If the actual position of the inner cover 3 is consistent with the expected position, the first linkage 41 and the second linkage 42 are both in the disengaged state.

[0057] According to an exemplary embodiment, the charging cover device comprises a sensor, the sensor is configured to sense whether the inner cover 3 is in the first position and / or the second position. It is conceivable that the sensor can only be used to sense whether the inner cover 3 is in one of the first position and the second position, and if the sensor is not in that position, the controller automatically determines that the inner cover 3 is in the other of the first position and the second position. Alternatively, a sensor can also be provided for each of the first position and the second position. The sensor, for example, involves a contact sensor or an optical sensor.

[0058] According to an exemplary embodiment, as shown in Figure 1 and Figure 2 , the charging cover device comprises a first limit portion 61 for preventing the inner cover 3 from exceeding the first position and / or a second limit portion 62 for preventing the inner cover 3 from exceeding the second position.

[0059] According to an exemplary embodiment, as shown inFigure 1 and Figure 2 As shown in Fig. 1, the linkage mechanism comprises a coupling device for achieving a coupled state of the linkage mechanism by coupling and a decoupled state of the linkage mechanism by decoupling, in which the opening movement of the outer cover 2 does not influence the inner cover 3 via the linkage mechanism. The coupling device comprises in particular a first coupling device 431 for the first linkage mechanism 41 and / or a second coupling device 432 for the second linkage mechanism 42. It is conceivable that the coupling device is in the decoupled state in the natural state or without an external influence and that the coupling device is brought into the coupled state only by a specific external influence. The controller is in particular for controlling the first coupling device 431 and / or the second coupling device 432 such that the inner cover 3 is in the desired position of the first position and the second position at least after the opening of the outer cover 2.

[0060] According to one exemplary embodiment, as shown in Fig. 1, the coupling device comprises a solenoid for generating a magnetic attraction when energized, whereby the coupling device is coupled, and for generating no magnetic attraction when de-energized, whereby the coupling device is decoupled. Here, the first coupling device 431 comprises a first solenoid 433 for the first linkage mechanism 41 and the second coupling device 432 comprises a second solenoid 434 for the second linkage mechanism 42. Figure 1 and Figure 2 As shown in Fig. 1, the coupling device comprises a solenoid for generating a magnetic attraction when energized, whereby the coupling device is coupled, and for generating no magnetic attraction when de-energized, whereby the coupling device is decoupled. Here, the first coupling device 431 comprises a first solenoid 433 for the first linkage mechanism 41 and the second coupling device 432 comprises a second solenoid 434 for the second linkage mechanism 42.

[0061] According to one exemplary embodiment, the coupling device comprises a negative pressure generator for generating a negative pressure attraction when in operation, whereby the coupling device is coupled, and for generating no negative pressure attraction when switched off, whereby the coupling device is decoupled.

[0062] According to one exemplary embodiment, the coupling device comprises a drive 435 for generating a movement, by which the coupling device is coupled and / or decoupled. Here, the coupling device can comprise in addition for example a return spring for decoupling and / or coupling the coupling device against the drive 435.

[0063] Figure 5 One example of a coupling device comprising a drive 435 is schematically shown in Fig. 1. As shown in Fig. 1, the coupling device comprises a first coupling element 481 and a second coupling element 482, such as two toothed wheels. The drive 435 can move the first coupling element 481, for example, such that the first coupling element 481 is coupled and / or decoupled with the second coupling element 482. In Fig. 1, the coupling device is decoupled or the first coupling element 481 is decoupled with the second coupling element 482. Figure 5 Figure 5 In Fig. 1, the coupling device is decoupled or the first coupling element 481 is decoupled with the second coupling element 482. Figure 6 The coupled state of the coupling device of Fig. 1 is schematically shown in Fig. 2. Here, the first coupling element 481 is coupled with the second coupling element 482. Figure 5

[0064] ​​Figure 7 Another example of a coupling device including a driver 435 is illustrated schematically. Figure 7 As shown, the coupling device includes a first coupling element 481, a second coupling element 482, and a reel 437. The reel 437 is connected to the first coupling element 481 and the second coupling element 482, for example, via a rope 436 (or a traction rope). Figure 7 In this case, the rope 436 is loose, so there is no motion coupling or decoupling between the first coupling element 481 and the second coupling element 482. Figure 8 Schematic illustration Figure 7 The coupling state of the coupling device. The coil 437 is pressed by the driver 435 (not shown). Figure 7 After rotating counterclockwise as shown, the rope 436 is taut, at which point there is motion coupling between the first coupling element 481 and the second coupling element 482. Alternatively, it can be imagined that the second coupling element 482 does not exist, and the coil 437 itself constitutes a coupling element that can couple and / or decouple from the first coupling element 482.

[0065] Besides the four coupling devices mentioned above, other implementations of coupling devices can be envisioned. These will not be exhaustively listed here.

[0066] The accompanying drawings are for illustrative purposes only, and therefore all components are shown in a simplified manner. The shape, size, number, and orientation of the components depicted in the drawings should not be considered as mandatory limitations. Those skilled in the art will readily conceive of various conventional variations in the shape, size, number, and orientation of the components, such as changing from a circle to a square, or from one to two, etc. In the drawings, the outer cover is exemplaryly located on the right side, and thus closer to the second charging port; the description in the specific embodiments is at least partially based on this. However, those skilled in the art will understand that if the outer cover were located on the left side and closer to the first charging port, the solution or elements of this application would undergo adaptive changes. Although the example only shows the outer cover pivoting while the inner cover translates, those skilled in the art will recognize that the basic idea of ​​this application can also be achieved through adaptive changes to the specific embodiments shown in the drawings, whether the outer cover is translated or pivoted and translated, or the inner cover is pivoted or pivoted and translated.

[0067] Although specific embodiments of this application are described in detail herein, they are given for illustrative purposes only and should not be construed as limiting the scope of this application. Various substitutions, modifications, and alterations can be conceived without departing from the spirit and scope of this application.
