DETAILED DESCRIPTION

[0022] In order to make the technical problems to be solved by the present application, technical solutions and beneficial technical effects more clearly understood, the present application will be further described in detail below with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the principles of the present application, but not to limit the protection scope of the present application.

[0023] Figure 1 A schematic view of an electric vehicle according to an exemplary embodiment of the present application is shown. As shown, the electric vehicle comprises a charging port cover structure 100. Figure 1

[0024] The charging port cover structure 100 can comprise a base body, inner covers and an outer cover. The base body can comprise at least one charging port, and correspondingly at least one inner cover can be provided to be rotatably connected to the base body to cover the at least one charging port respectively. The outer cover is located outside the at least one inner cover and can be rotatably connected to the vehicle body of the electric vehicle.

[0025] Figure 2 A schematic view of a charging port cover structure 100 according to an exemplary embodiment of the present application is shown, wherein the base body 1 of the charging port cover structure 100 comprises two charging ports, i.e. a first charging port 11 and a second charging port 12, arranged side by side for example. Herein, the first charging port 11 is a direct current charging port in particular, and the second charging port 12 is an alternating current charging port in particular. Correspondingly, the charging port cover structure 100 comprises a first inner cover 21 and a second inner cover 22. The first inner cover 21 is used to cover the first charging port 11 on the inner side respectively, and the second inner cover 22 is used to cover the second charging port 12 on the inner side respectively. The charging port cover structure 100 further comprises an outer cover 3, which is located outside the first inner cover 21 and the second inner cover 22 away from the charging ports. That is, when both the inner and outer covers are closed, the base body 1, the first inner cover 21 and the second inner cover 22, and the outer cover 3 are sequentially arranged from the inside to the outside with respect to the vehicle body.

[0026] In particular, the at least one inner cover, i.e. the first inner cover 21 and / or the second inner cover 22, can comprise a display screen for displaying charging related information. Preferably, both the first inner cover and the second inner cover can comprise a display screen.

[0027] Figure 3 A schematic view of an inner cover of a charging port cover structure according to an exemplary embodiment of the present application is shown. Figure 4 A schematic view of an inner cover of a charging port cover structure according to an exemplary embodiment of the present application is shown. Figure 3 A schematic view of the internal structure of a charging port cover structure according to an exemplary embodiment of the present application is shown. As shown, Figure 3 and Figure 4 ​As shown, in this embodiment, the first inner cover 21 comprises a first display screen 211, and the second inner cover 22 comprises a second display screen 221.

[0028] In the prior art, there is a scheme of arranging a display screen on a base body. However, in this scheme, the display screen will occupy the area on the base body, which limits the further miniaturization design of the base body. In comparison, according to the present application, the integration of the display screen into the inner cover can allow the further miniaturization design of the charging port cover structure, and is conducive to realizing a compact structure.

[0029] There is also a scheme of arranging a display screen on an outer cover in the prior art. However, such a scheme is not conducive to the display screen as a precision electronic device on the one hand because the outer cover faces the outside of the vehicle, and environmental factors are not conducive to the display screen. On the other hand, if the display screen is arranged on the inner side of the outer cover, the user needs to observe the display screen on the inner surface of the outer cover when the outer cover is in an open state. Since the user's line of sight direction is facing the inner cover and the charging port when performing a charging operation (such as inserting a charging gun), the open outer cover deviates from the user's line of sight direction. Therefore, in comparison, according to the present application, the integration of the display screen into the inner cover can not only protect the inner cover and the display screen through the outer cover, but also facilitate the user to observe the charging related information displayed on the display screen due to the closer distance between the inner cover and the charging port.

[0030] Preferably, the display screens 211, 221 are oriented and embedded in the inner covers 21, 22 with their display surfaces facing outward. In this way, the charging related information can be presented to the user through the display screens when the inner covers are in a closed state (i.e., covering the corresponding charging port). This can be done without opening the inner covers.

[0031] In particular, the display screen 211, 221 of one of the first inner cover 21 and the second inner cover 22 can display the charging related information corresponding to the one when the other of the first inner cover 21 and the second inner cover 22 is in an open state. For example, when the first inner cover 21 is opened to perform a direct current charging operation, the second inner cover 22 can always remain in a closed state, and the display screen 221 of the second inner cover 22 can display the charging related information associated with the direct current charging operation. In this way, the user can conveniently observe the display screen to obtain the charging related information without adjusting the line of sight direction, especially during the gun insertion operation.

[0032] Preferably, the lateral extension range (in Figure 3 shown in a broken oblique section line) of the display screens 211, 221 can be at least half of the lateral extension range of the corresponding inner covers 21, 22. That is, a large area display screen can be integrated in the inner cover, so as to arrange a larger display area in the limited space of the charging port cover structure. In this way, the charging related information can be presented in a multi-form and user-friendly manner.

[0033] For example, in some embodiments, with reference to Figure 3 and Figure 4 The inner cover 21, 22 can include a receiving recess for receiving the display screen 211, 221 and a bezel portion circumferentially surrounding the receiving recess, and a pivot structure for rotatably connecting the inner cover to the base body can be connected to one side of the bezel portion. The bezel portion can be deflected toward the base body relative to the receiving recess to be able to contact the base body to achieve coverage of the charging port. In the lateral extension range of the inner cover, for example, from the outer surface of the inner cover shown, the width of the bezel portion can be as small as possible while meeting the structural strength requirements. Thus, the size of the receiving recess and the display screen received therein can be enlarged. Figure 3

[0034] In addition, in some embodiments, the inner cover can not have the above-mentioned bezel portion, i.e., the display screen can almost extend to the entire inner cover. At this time, the display screen can be a curved screen in particular, which can also provide display function on the circumferential side of the inner cover.

[0035] The above-mentioned display screen 211, 221 can be any suitable screen type. In particular, the display screen 211, 221 can be a liquid crystal screen.

[0036] Optionally, with reference to Figure 4 The inner cover 21, 22 can further include a transparent protective layer 212, 222 arranged on the outer side of the display screen 211, 221. In particular, the transparent protective layer 212, 222 can define the outer surface of the inner cover 21, 22. By means of the transparent protective layer, the display screen can be prevented from being scratched and the visual effect of the display screen can not be affected, in addition, the display screen 211, 221 can also be provided with structural strength. Exemplarily, the transparent protective layer is formed of tempered glass or transparent plastic. Additionally or alternatively, the inner cover 21, 22 can further include a circuit board 213, 223 arranged on the inner side of the display screen 211, 221. Thus, the display state of the display screen 211, 221 can be controlled by controlling the working state of the circuit board. At this time, the circuit board and the display screen can be embedded in the inner cover as a display assembly. Here, the outer side of the display screen can be the side thereof facing the outside of the vehicle body, and the inner side of the display screen can be the side thereof facing the inside of the vehicle body.

[0037] ​Preferably, the inner cover 21, 22 can comprise a transparent protective layer 212, 222, a display screen 211, 221 and a circuit board 213, 223 arranged in a stack from outside to inside along the thickness direction thereof. In particular, the outer surface of the inner cover can be defined by the transparent protective layer, and the inner surface of the inner cover can be defined by the circuit board. That is, the assembly consisting of the transparent protective layer, the display screen and the circuit board can itself serve as the inner cover, thereby achieving coverage of the charging port. Alternatively, the inner cover can have a receiving recess with a bottom, i.e. the circuit board is attached to the bottom of the receiving recess to provide protection for the circuit board. Figure 5 The inner surface of the bottom is shown in a grid hatch.

[0038] Optionally, the inner cover 21, 22 can further comprise a pressure sensing unit, by means of which the inner cover 21 is configured to be able to touch open and close and / or stop the charging operation. For example, the pressure sensing unit can be arranged between the transparent protective layer 212, 222 and the display screen 211, 221. By adjusting the size and arrangement position of the pressure sensing unit, the touch function can be provided at the desired position of the inner cover 21, 22. For example, the touch function can be provided throughout the range of the display screen, or alternatively, the touch function can be provided locally on the display screen. In this way, the inner cover can be opened and closed and / or the charging operation can be stopped by one-key touch. In addition, the touch area for controlling the opening and closing of the inner cover can be arranged separately from the touch area for controlling the stopping of the charging operation.

[0039] In order to achieve the relative rotation connection of the inner cover to the base body, a pivot structure can be used. Referring to Figure 3 , the first inner cover 21 can be connected to the base body 1 through a first pivot structure 231, and the second inner cover 22 can be connected to the base body 1 through a second pivot structure 232. Preferably, the first pivot structure 231 and the second pivot structure 232 can be located between the first charging port 11 and the second charging port 12 arranged side by side. Further, the pivot axes defined by the first pivot structure 231 and the second pivot structure 232 can be collinear. For example, the first pivot structure 231 and the second pivot structure 232 can comprise the same pivot shaft, and the first inner cover 21 and the second inner cover 22 can be arranged in a space position offset manner to be jointly sleeved on the common pivot shaft. In this way, a particularly compact base body design and charging port cover structure design can be achieved. At the other side of the charging port opposite to the pivot shaft, a locking structure for locking the corresponding inner cover is provided on the base body 1. By means of the locking structure, the locking and unlocking of the inner cover can be achieved, thereby making the inner cover in a closed state or an open state.

[0040] Figure 5 A schematic view of the inner cover and the base body of the charging port cover structure according to another exemplary embodiment of the present application is shown; Figure 6 A schematic view of the inner cover and the base body of the charging port cover structure according to another exemplary embodiment of the present application is shown; Figure 5A schematic diagram of the internal structure of the charging port cover shown. Figure 3 and Figure 4 The difference between the illustrated embodiment and the one shown is that, in Figure 5 and Figure 6 In the illustrated embodiment, the first pivot structure 231 may be located on the side of the first charging port 11 away from the second charging port 12, and the second pivot structure 232 may be located on the side of the second charging port 12 away from the first charging port 11. That is, in this embodiment, the first pivot structure 231 and the second pivot structure 232 are respectively arranged on both sides of the first charging port 11 and the second charging port 12 arranged side by side. A locking structure for locking the corresponding inner cover may be provided on the base 1 between the first charging port 11 and the second charging port 12.

[0041] Preferably, in the above two embodiments, such as Figure 4 and Figure 6 As shown, the wiring harnesses of displays 211 and 221 can be constrained by corresponding pivot structures 231 and 232, extending from the corresponding inner covers 21 and 22 to the inner side of the base 1. That is, the wiring harness routing can be constrained by the pivot structure. In a specific example, the pivot structure may be provided with a wiring groove for receiving the wiring harnesses of the displays. The wiring harnesses of circuit boards 213 and 223 may be the same as or bundled with the wiring harnesses of displays 211 and 221. The wiring harnesses include signal lines and power lines.

[0042] Alternatively, in another specific example, the base 1 can be provided with a pin connector that connects to the controller via a wiring harness. Correspondingly, the inner cover can be provided with an adapter connector, through which the display screen and the controller can be electrically connected. This design facilitates the replacement or upgrading of either the display screen or the inner cover.

[0043] Preferably, in some embodiments, the charging port cover structure 100 may further include a microcontroller unit 4 for controlling the displays 211, 221 to display charging-related information. This microcontroller unit 4 may be arranged, in particular, on the side of the base 1 facing the vehicle interior for concealment. That is, extending into the interior of the base 1, the wiring harness may, for example, be connected to the microcontroller unit 4 located inside the base 1.

[0044] Further, in some embodiments, the micro control unit 4 can be communicatively connected to a central information controller CIC and / or a battery management system BMS of the electric vehicle, to be controlled by the CIC and / or the BMS. Thus, the micro control unit 4 can be controlled by the CIC and / or the BMS, based on user instructions and / or vehicle instructions collected from the vehicle side, to control the display state of the display screen 211, 221 by controlling the working state of the circuit board. The connection between the CIC and / or the BMS and the micro control unit 4, and between the micro control unit 4 and the display screen (and the circuit board), can be made, for example, through a LIN bus.

[0045] Optionally, the charging related information can include at least one of welcome information, charging preparation information, charging information, and error and fault reminding information. Figure 7 Exemplary schematic diagrams of display contents of the display screen of the charge port cover structure according to exemplary embodiments of the present application are shown. In the following, various types of charging related information and corresponding forms of presentation are described in conjunction with Figure 7

[0046] The welcome information can be displayed before the charging starts, for example, after the outer cover 3 is opened or before the charging gun is inserted into the charge port. In Figure 7 In (a), a vehicle brand LOGO is schematically shown. The LOGO can be displayed in the display screen as at least a part of the welcome information in a static and / or dynamic (e.g. rotating) manner. In addition, the welcome information can also include textual and / or numerical information indicating the current battery status, such as the text "battery is in a low power state" or "please charge", or the text "power level" coupled with the number "5%" and the like.

[0047] The charging operation can include a charging preparation phase and a charging phase. The charging preparation phase can include a step of confirming the matching and electrical connectivity after the charging gun is physically connected to the charge port. Therefore, the charging preparation information can particularly include information indicating that the current is in the charging preparation phase, the charging preparation progress, and / or the charging preparation phase result (e.g. successful connection). The charging phase refers to the phase from the start of charging to the end of charging, and the charging information can particularly include the charging mode, the charging state parameter, the charging progress, the current power level, and / or the charging phase result (e.g. full charge, charging duration, battery health status, etc.). For example, the charging state parameter can include charging voltage, charging current, cumulative charging amount, and the like. The charging progress can be represented by the charging completion degree or the remaining charging time.

[0048] In Figure 7 ​In the diagram, (b) and (c) schematically illustrate progress bars reflecting the completion status of a stage. (b) includes both the progress bar and numerical values, while (c) adds text information to (b). For example, the text "Communication protocol in progress" could be displayed, along with a combination of a progress bar and numerical values ​​to indicate the charging preparation progress, such as 80% or 5 seconds. This would suggest that the communication protocol is currently in progress and is 80% complete, or that 5 seconds remain until 100% completion. Alternatively, it could be as follows... Figure 7 The (d) diagram illustrates the form, displaying text such as "Waiting to charge", "Charging gun connected", and "Communication connection in progress, estimated time 9 seconds" in different locations.

[0049] For example, it can be like Figure 7 The schematic representation in (c) uses a progress bar and numerical display of 30%, along with the text "Charging," to indicate that charging is in progress and that 30% of the charging phase has been completed. Alternatively, it can be as follows: Figure 7 As shown in (d), the display screen shows text such as "Charging gun successfully connected, super fast charging in progress", "Charging status normal", and "Estimated to be fully charged in 5 minutes".

[0050] Errors or malfunctions may occur during the charging preparation and charging phases, such as charging gun incompatibility, incorrect charging gun connection, or charging overload. Therefore, when these errors or malfunctions are detected, the following steps can be taken: Figure 7 As shown in (d), error and fault warning messages are displayed in text form on the screen. For example, the text "Error code: Communication failed, please replace the charging gun" is displayed.

[0051] Figure 7 (e) schematically illustrates a virtual button for "one-click charging stop". Users can stop charging with a single touch by touching this virtual button. The virtual button may include prompts such as "Stop charging" or "Press and hold for 3 seconds".

[0052] Preferably, users can customize the specific content and presentation format of charging-related information according to their preferences. Additionally, users can customize the various functional zones of the inner cover display screen, such as the touch area and different display areas for displaying different charging-related information.

[0053] Therefore, through any of the methods described above or any combination thereof, the inner cover with a display screen according to the present invention can have a rich information display function, thereby enhancing the technological feel of the vehicle.

[0054] Figure 8 A flowchart illustrating an exemplary control method for a charging port cover structure according to an exemplary embodiment of the present invention is shown. Figure 8As shown, the control method can include step S1, step S2 and step S3.

[0055] In step S1, in response to the outer cover 3 being opened, the display screens 211, 221 of the inner covers 21, 22 are controlled to enter a standby state or display welcome information. Here, the opening of the outer cover 3 can be detected in a suitable manner, such as detecting that the locking structure for the outer cover 3 switches to an unlocked state, detecting a change in the position of the outer cover 3 through a position sensor or a visual sensor, or detecting that the light intensity becomes stronger through an optical sensor arranged on the inner side of the outer cover 3, etc. The outer cover 3 can be opened by the user or opened by a charging robot. In some cases, the central information controller CIC and / or the battery management system BMS of the vehicle can determine that the outer cover 3 is opened through the information it collects, and in response, send a display screen control instruction to the display screen or the micro control unit to control the display screen to enter a standby state or display welcome information. For example, in response to the outer cover 3 being opened, the micro control unit 4 can be controlled to start working, and at the same time, wake up the display screens 211, 221 of the first inner cover 21 and the second inner cover 22. In particular, the display screens in the two inner covers can be integrated into one whole to display welcome information in coordination.

[0056] In step S2, in response to the inner covers 21, 22 being opened, the display screens 211, 221 are controlled to display charging preparation information and charging information according to the charging operation phase. Similarly, the opening of the inner covers 21, 22 can be detected in the same or similar manner as described above. For example, when the charging gun is inserted into the charging port, the display screen displays charging preparation information, and switches to a display interface of charging information when the charging preparation phase is completed and enters the charging phase. The display interface of the charging information can contain a virtual button for implementing "one-key stop charging". When the charging port cover has the first inner cover 21 and the second inner cover 22, the charging preparation information and the charging information can be displayed based on the opened inner cover. For example, when the first inner cover 21 covering the direct current charging port is opened, the charging preparation information and the charging information related to the direct current charging operation are displayed in the display screen 221 of the second inner cover 22.

[0057] In step S3, in response to a charging stop instruction or the charging gun being pulled out of the charging port 11, 12, the display screens 211, 221 are controlled to return to a standby state or a shutdown state. The charging stop instruction can be, for example, a touch operation of the user on the virtual button for "one-key stop charging", or can be a vehicle instruction, a charging equipment instruction or a user instruction received by the central information controller CIC and / or the battery management system BMS. Thus, energy saving can be achieved.

[0058] Further embodiments of the application also relate to an electric vehicle comprising a charging port cover structure 100 according to any of the application.

[0059] Those skilled in the art can combine and combine the different embodiments or examples described in the specification and the features of the different embodiments or examples without contradiction.

[0060] Although specific implementations of the application have been described herein, they are not to be taken as limitations on the scope of the application. Various changes and modifications can be suggested to one skilled in the art, and it is intended that the application encompass such changes and modifications as fall within the scope of the appended claims.
