Users need to press a specific area on the outer panel of the cover to trigger a mechanical switch on the inner base to open or close the cover.

[0030] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely a part of the embodiments of this application, and not all of the embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein. Based on the embodiments of this application described herein, all other embodiments obtained by those skilled in the art without inventive effort should fall within the protection scope of this application.

[0031] like Figure 1 As shown, this application embodiment provides a charging port cover 100 for an electric vehicle. The charging port cover 100 is provided with a cover switch module 110. The housing of the cover switch module 110 includes a first sensor 111, a second sensor 112, and a processor 113 electrically connected to the first sensor 111 and the second sensor 112. The first sensor 111 generates a first signal when it is touched; the second sensor 112 generates a second signal when the first sensor 111 is slid-touched; the processor 113 determines a touch signal based on the first signal, determines a sliding direction signal based on the second signal, and generates a control signal when the touch signal satisfies a first opening condition and the sliding direction signal satisfies a second opening condition, so as to automatically open the charging port cover 100.

[0032] According to an embodiment of this application, a charging port cover 100 for an electric vehicle includes a cover switch module 110. A first sensor 111 and a second sensor 112 are mounted on the cover switch module 110, generating a first signal and a second signal respectively when touched. The first signal reflects the user's touch behavior, i.e., whether the first sensor 111 is touched. Generally, touching the first sensor 111 generates a first signal (the specific type of the first signal depends on the type of the first sensor, as described in the following examples); not touching the first sensor 111 does not generate a first signal. The second signal reflects the user's sliding touch behavior (the specific type of the second signal depends on the type of the second sensor, as described in the following examples), and generates a sliding direction signal based on it. That is, a sliding direction signal is only generated when the user performs a sliding touch; unintentional touches by the user are generally considered point touches and do not generate a sliding direction signal. The processor 113 in the cover switch module 110 determines the touch signal based on the first signal and the sliding direction signal based on the second signal. The processor 113 will control the charging port cover to open only when both of these conditions are met. Therefore, the charging port cover 100 in this application can recognize the user's touch gestures and will only open when the touch and the sliding direction meet the conditions, which improves the accuracy of recognition, avoids accidental opening of the cover and enhances the interactivity with the user.

[0033] For example, the first sensor 111 includes at least two touch-sensitive strips, each of which generates a capacitance value when touched (the first signal mentioned above is the capacitance value in this example), and the touch signal is the sum of the capacitance values ​​generated by the at least two touch-sensitive strips. The first opening condition includes: the sum of the capacitance values ​​generated by the at least two touch-sensitive strips is greater than or equal to a preset threshold.

[0034] Multiple touch-sensitive strips are placed at designated locations. Each capacitance reading indicates that the corresponding touch-sensitive strip has been touched. For a preset threshold, if the number of touch-sensitive strips is N and the capacitance value is X, the preset threshold can be set to be greater than (N-1)*X and less than or equal to N*X. When the sum of the generated capacitance values ​​is greater than or equal to this preset threshold, it indicates that all touch-sensitive strips have been touched, the touch gesture is at the correct designated location, and the first opening condition is met.

[0035] For example, the above-mentioned at least two touch-sensitive strips are arranged in a preset direction, and the first sensor 112 unit includes an acceleration sensor disposed on one of the touch-sensitive strips.

[0036] The accelerometer sequentially generates touch position coordinates (the second signal mentioned earlier is the touch position coordinate in this example) when each touch-sensitive strip is touched. The sliding direction signal is the absolute value of the difference between each touch position coordinate and a reference coordinate, which is the position coordinate of the accelerometer. The second opening condition includes: the trend of the absolute value of the difference between the touch position coordinates of each touch-sensitive strip arranged in a preset direction and the reference coordinate is related to the preset direction.

[0037] An accelerometer is placed on a designated touch-sensitive strip. After touching and swiping across a touch-sensitive strip, corresponding coordinates are generated. The difference between these coordinates and the reference coordinates reflects the position information of the touch-sensitive strip. When the trend of the coordinate difference generated along the gesture swipe direction is associated with a preset direction, the second opening condition is met. For example, the preset direction is from the first touch-sensitive strip to the second touch-sensitive strip. An accelerometer is placed on the first touch-sensitive strip. If a touch first passes through the first touch-sensitive strip, a coordinate difference based on this strip is obtained. Passing through the next touch-sensitive strip yields a coordinate difference based on that strip. Because the two coordinates are further away from the reference coordinates, the trend of the coordinate difference gradually increases, associating with the preset direction and meeting the second opening condition. Conversely, if the trend gradually decreases, it is not associated with the preset direction and the second opening condition is not met.

[0038] Now combine Figures 2 to 4 A more detailed description of the charging port cover's structure.

[0039] like Figure 2 and Figure 3 The diagram shown is a structural schematic of the charging port cover in an embodiment of this application. The charging port cover includes a base plate 4, an outer plate 2, and a connecting plate 3, wherein the connecting plate 3 connects the outer plate 2 and the base plate 4. A port switch module is disposed in the interlayer between the outer plate 2 and the connecting plate 3. When the charging port cover is opened, the outer plate 2 is in an open state relative to the base plate 4. Exemplarily, the base plate 4 is fixedly mounted on the body 1 of the electric vehicle.

[0040] like Figure 4 The diagram shown is a structural schematic of the lid switch module 5 in this embodiment. The lid switch module 5 has a metal base 501 and a printed circuit board 502 mounted on the metal base inside its housing. A first sensor, a second sensor, and a processor are integrated on the printed circuit board. Exemplarily, the printed circuit board 502 is a PCB board, and the first sensor includes three touch-sensitive strips 503 arranged sequentially on the printed circuit board, with the touch-sensitive strips 503 positioned along a preset direction.

[0041] For example, the touch-sensitive strip 503 includes a first sensing strip, a second sensing strip, and a third sensing strip arranged from left to right, with an acceleration sensor disposed on the first sensing strip.

[0042] The second opening condition includes: the absolute values ​​of the differences between the touch position coordinates corresponding to the first, second, and third sensor strips and the reference coordinates, which increase sequentially.

[0043] When opening the lid by touch, the user needs to touch the first sensor strip, the second sensor strip, and the third sensor strip in sequence to open the lid.

[0044] For example, the capacitance values ​​generated by the first, second, and third sensor strips are all X. A preset threshold can be set to be greater than 2X and less than or equal to 3X. When the user first touches the first sensor strip, it generates a first capacitance value. Similarly, the second and third sensor strips generate second and third capacitance values ​​after being touched. The processor obtains the first to third capacitance values ​​and calculates their sum. If the sum is greater than or equal to the preset threshold, the first touch condition is met. If all three sensor strips are not fully touched, the generated capacitance value will definitely be less than the preset threshold, and the first opening condition will not be met.

[0045] Because the accelerometer is located on the first sensor strip, when the touch process occurs, the user slides sequentially across the first to third sensor strips in a preset direction. During this slide, coordinate values ​​related to the first to third sensor strips will appear sequentially. The absolute value of the difference between these coordinate values ​​and the reference coordinates will increase sequentially, satisfying the second opening condition. The cover can then be opened successfully if both the first and second opening conditions are met. If the sliding direction is reversed, the absolute value of the difference between the coordinate values ​​related to the first to third sensor strips and the reference coordinates will decrease sequentially, failing to satisfy the second opening condition, and the cover cannot be opened.

[0046] For example, the first sensor includes a first sensing strip, a second sensing strip, and a third sensing strip arranged from left to right, with an acceleration sensor disposed on the third sensing strip. The second opening condition includes: the absolute values ​​of the differences between the touch position coordinates corresponding to the first, second, and third sensing strips and the reference coordinates decrease sequentially.

[0047] The preset threshold can be set to be greater than 2X and less than or equal to -3X. The preset direction is from the first sensor strip to the third sensor strip. When the user touches the first sensor strip, it generates a first capacitance value. Similarly, after the second and third sensor strips are touched, they generate second and third capacitance values, respectively. The processor obtains the first to third capacitance values ​​and calculates their sum. If the sum of these three capacitance values ​​is greater than or equal to the preset threshold, the first touch condition is met. If all three sensor strips are not completely touched, the generated capacitance value will definitely be less than the preset threshold, and the first opening condition will not be met.

[0048] Because the accelerometer is located on the third sensor strip, during the touch process, when sliding along the preset direction from the first to the third sensor strip, coordinate values ​​related to the first to third sensor strips will appear sequentially during the sliding. Therefore, with the accelerometer on the third sensor strip, the accelerometer gradually approaches the reference coordinates from the first to the third sensor strip, resulting in smaller and smaller coordinate differences. If the absolute value of the difference between the coordinate values ​​and the reference coordinates decreases sequentially during the sliding process, it indicates that the sliding direction is from the first to the third sensor strip and gradually approaches the reference coordinates, satisfying the second opening condition. The cover can be opened smoothly based on satisfying both the first and second opening conditions. If the sliding direction is reversed, the absolute value of the difference between the coordinate values ​​related to the first to the third sensor strips and the reference coordinates increases sequentially, failing to satisfy the second opening condition, and the cover cannot be opened.

[0049] For example, based on the above method, the accelerometer can also be set on the second sensing strip, with the reference coordinate located on the second sensing strip. When the cover is opened by a touch gesture, the user slides sequentially from the first sensing strip to the third sensing strip in a preset direction, gradually approaching and then moving away from the reference coordinate. The change in coordinate difference is reflected in the following: during the sliding process, the absolute value of the difference between the touch position coordinates corresponding to the first, second, and third sensing strips and the reference coordinate first decreases and then increases, thus satisfying the second opening condition; otherwise, the second opening condition is not satisfied.

[0050] For example, the processor includes a first control unit and a second control unit, wherein the first control unit is configured to determine a touch signal based on a first signal and a sliding direction signal based on a second signal. The second control unit is configured to generate a control signal to automatically open the charging port cover when the touch signal satisfies a first opening condition and the sliding direction signal satisfies a second opening condition.

[0051] For example, the charging port cover also includes a register for storing a first signal and a second signal. When the touch signal does not meet the first opening condition or the sliding direction signal does not meet the second opening condition, the processor sends an indication signal to the register, causing the register to delete the first and second signals. For example, the charging port cover also has a closing button; when the closing button is triggered, the charging port cover automatically closes.

[0052] like Figure 5 The diagram shows a flowchart of the charging port cover opening based on touch gestures in an embodiment of this application. After the initialization of the gesture trend recognition process is completed, the current recognition process begins. First, the first control unit detects whether the user's finger touches the outer panel in a designated area, that is, whether the first opening condition is met. If the condition is met, the process of sliding to open the port cover begins. The second control unit detects whether the sliding direction of the touch gesture meets the second opening condition. If it is met, the port cover opens, and the gesture recognition process ends. If it is not met, the port cover does not open, the gesture recognition process ends, and the registered data is deleted for initialization, waiting for the next touch gesture recognition.

[0053] According to an embodiment of this application, a charging port cover for an electric vehicle includes a cover switch module. The cover switch module has a first sensor and a second sensor, which generate a first signal and a second signal respectively when touched. The first signal reflects the user's touch action, i.e., whether the first sensor has been touched. Generally, touching the first sensor generates the first signal; not touching it does not generate the first signal. The second signal reflects the user's sliding touch action and generates a sliding direction signal. That is, a sliding direction signal is only generated when the user performs a sliding touch; unintentional touches are generally point touches and do not generate a sliding direction signal. The processor in the cover switch module determines the touch signal based on the first signal and the sliding direction signal based on the second signal. The processor only controls the charging port cover to open when both signals meet certain conditions. Therefore, the charging port cover in this application can recognize the user's touch gestures and only opens when a touch is performed and the sliding direction meets the conditions, improving recognition accuracy, preventing accidental opening of the cover, and enhancing user interactivity.

[0054] like Figure 6As shown in the figure, this application embodiment also provides a control system for a charging port cover of an electric vehicle. The control system includes a charging port cover, a domain controller 7 electrically connected to the charging port cover, and an execution unit 6. Wherein: the charging port cover is the charging port cover described above according to the embodiment of this application. After the processor of the charging port cover generates a control signal, it sends the control signal to the domain controller 7. The domain controller 7 sends an opening command to the execution unit 6 based on the control signal. The execution unit 6 opens the charging port cover based on the opening command, and the outer cover plate 2 on the charging port cover opens.

[0055] For example, the aforementioned cover closing button is connected to the execution component. When the cover closing button is triggered, a signal is sent to the execution component, and the execution component controls the charging port cover to close.

[0056] This application also discloses an electric vehicle, which is equipped with the above-mentioned control system for the charging port cover of the electric vehicle. The control system for the charging port cover is used to control the opening of the charging port cover on the electric vehicle.

[0057] The electric vehicle and charging port cover control system of this application embodiment are provided with a first sensor and a second sensor on the cover switch module, which generate a first signal and a second signal respectively when touched. The first signal reflects the user's touch situation, i.e., whether the first sensor has been touched. Generally, the first signal is generated when the first sensor is touched; no first signal is generated when the first sensor is not touched. The second signal reflects the user's sliding touch situation and generates a sliding direction signal based on it. That is, a sliding direction signal can only be generated when the user makes a sliding touch; unintentional touches by the user are generally point touches and cannot generate a sliding direction signal. The processor in the cover switch module is used to determine the touch signal based on the first signal and the sliding direction signal based on the second signal. The processor will control the charging port cover to open only when both of these meet certain conditions. Therefore, the charging port cover in this application can recognize the user's touch gesture and will only open when a touch is made and the sliding direction also meets the conditions, improving the accuracy of recognition, avoiding accidental opening of the cover, and enhancing the interactivity with the user.

[0058] like Figure 7 As shown, this application embodiment also provides an automatic opening method for the charging port cover of an electric vehicle. This method can be executed by the processor of the charging port cover of the electric vehicle according to the embodiment of this application described above. Its operation has been described in detail above, and for the sake of brevity, the details will not be repeated here, only some main operations will be described. Figure 7 As shown, the method may include the following steps:

[0059] S710: Obtain the first signal output by the first sensor on the charging port cover. The first signal is generated when the first sensor is touched.

[0060] S720: Obtain the second signal output by the second sensor on the charging port cover. The second signal is generated by the second sensor when the first sensor is slid-touched.

[0061] S730: Determine a touch signal based on a first signal, determine a sliding direction signal based on a second signal, and generate a control signal when the touch signal meets the first opening condition and the sliding direction signal meets the second opening condition, so as to automatically open the charging port cover.

[0062] For example, the first sensor includes at least two touch-sensitive strips, each of which generates a capacitance value when touched; the touch signal is the sum of the capacitance values ​​generated by the at least two touch-sensitive strips; the first opening condition includes: the sum of the capacitance values ​​generated by the at least two touch-sensitive strips is greater than or equal to a preset threshold.

[0063] For example, at least two touch-sensitive strips are arranged in a preset direction, and the second sensor unit includes an accelerometer disposed on one of the touch-sensitive strips. The accelerometer sequentially generates touch position coordinates when each touch-sensitive strip is touched. The sliding direction signal is the absolute value of the difference between each touch position coordinate and a reference coordinate, which is the position coordinate of the accelerometer.

[0064] The second opening condition includes: the absolute value of the difference between the touch position coordinates of each touch sensor strip arranged in a preset direction and the reference coordinates, and the trend of the change of the absolute value of the difference is related to the preset direction.

[0065] When both the first and second opening conditions are met, the processor generates a control signal to open the charging port cover, thus achieving effective control of the charging port cover.

[0066] like Figure 8 As shown in the figure, this application embodiment also provides a control method for a charging port cover of an electric vehicle, which is executed by a control system of the charging port cover. The control system includes a charging port cover, a domain controller electrically connected to the charging port cover, and an execution component. The charging port cover is the charging port cover described above. The method includes:

[0067] After the processor of the S810 charging port cover generates the control signal, it sends the control signal to the domain controller.

[0068] The S820 and the domain controller send an open cover command to the actuator based on the control signal, and the actuator opens the charging port cover based on the open cover command.

[0069] For example, the processor of the charging port cover generates a control signal, including: a first sensor of the charging port cover generating a first signal when touched; a second sensor of the charging port cover generating a second signal when the first sensor is slidably touched; the processor determining a touch signal based on the first signal, determining a sliding direction signal based on the second signal, and generating a control signal when the touch signal satisfies a first opening condition and the sliding direction signal satisfies a second opening condition.

[0070] The automatic opening method and control method for the charging port cover of an electric vehicle according to embodiments of this application include a first sensor and a second sensor in the cover switch module, which generate a first signal and a second signal respectively when touched. The first signal reflects the user's touch situation, i.e., whether the first sensor has been touched. Generally, the first signal is generated when the first sensor is touched; otherwise, it is not generated. The second signal reflects the user's sliding touch situation and generates a sliding direction signal. That is, a sliding direction signal is only generated when the user performs a sliding touch; unintentional touches by the user are generally point touches and do not generate a sliding direction signal. The processor in the cover switch module determines the touch signal based on the first signal and the sliding direction signal based on the second signal. The processor controls the charging port cover to open only when both meet certain conditions. Therefore, the charging port cover in this application can recognize the user's touch gesture and will only open when a touch is performed and the sliding direction meets the conditions, improving the accuracy of recognition, avoiding accidental opening of the cover, and enhancing user interactivity.
