A charging port system 100 for electric vehicles is provided according to an embodiment of the present disclosure. Referring to Figure 1, the charging port system The system 100 includes: a charging port (not shown in Figure 1) and a charging port cover 120. The charging port cover 120 is used to close or open the charging port. The charging port cover 120 includes an inner cover 121 and an outer cover 122. , the inner cover 121 is located at the charging port, and the outer cover 122 is located outside the inner cover 121; the charging port cover 120 also includes a driving device 130, and the driving device 130 is used to drive the The charging port cover 120 moves between an open position and a closed position; the driving device 130 is configured to first move the outer cover 122 from the closed position to the open position, and then drive the inner cover 121 to move from the closed position. to the open position.

It should be noted that the charging port system 100 of the embodiment of the present disclosure can not only be applied to new energy electric vehicles, but also can be applied to various types of vehicles such as electric motorcycles and electric mopeds. The specific description of electric vehicles in this disclosure is There are no restrictions on types.

In the solution of the embodiment of the present disclosure, an inner cover 121 and an outer cover 122 are arranged sequentially from the inside to the outside on the charging port of the electric vehicle, and a driving device 130 is provided for the inner cover 121 and the outer cover 122. The driving device 130 can The switches of the inner cover 121 and the outer cover 122 are automatically controlled.

Among them, the inner cover 121 can protect the charging port. The outer cover 122 can protect the inner cover 121 and also protect the charging port.

In related technologies, the charging port cover on an electric vehicle is usually opened by pressing the charging port cover actuator after unlocking the vehicle or manually opening the outer cover. The inner cover also needs to be manually pulled out before charging can begin. This process It requires human beings to actively operate the opening action twice (ie, opening the outer cover and the inner cover), and the entire operation process is relatively cumbersome and complicated.

The solution of the disclosed embodiment is that when the charging port needs to be opened, the driving device 130 can control the outer cover 122 to automatically open first, and then control the inner cover 121 to automatically open. The outer cover 122 and the inner cover 121 are designed to be linked. In this way, the charging port can be opened through automated control. It can be seen that in the solution of the present disclosure, the opening of the charging port can be driven and controlled by the driving device 130, and there is no need for manual manual opening actions. The entire operation process is highly automated and simple.

In the charging port system of the embodiment of the present disclosure, when the charging port needs to be closed, the inner cover 121 and the outer cover 122 can also be automatically closed through the driving device 130, and the user does not need to manually operate the inner cover 121 and the outer cover 122 during the entire process. , the inner cover 121 and the outer cover 122 can be closed in conjunction with each other through the driving device 130 .

According to embodiments of the present disclosure, through the above technical solution, the manual operation steps of controlling the switch of the charging port on the electric vehicle can be simplified, and the linked opening and/or opening of the inner cover 121 and the outer cover 122 on the charging port can be realized through automated control. It is closed, and the user does not need to manually touch the inner cover and outer cover during the opening and closing process of the charging port, which can improve the user's human-computer interaction experience.

In some examples of the present disclosure, referring to FIG. 1 , the driving device 130 includes a first driving device 131 and a second driving device 132 , the outer cover 122 is connected to the first driving device 131 , and the inner cover 121 Connected to the second driving device 132 .

Among them, the first driving device 131 is a device that drives the outer cover 122 to move to perform an opening or closing action. The second driving device 132 is a device that drives the inner cover 121 to move to perform an opening or closing action.

For example, the first driving device 131 and the second driving device 132 may be motors.

Specifically, referring to FIG. 1 , the first driving device 131 can be controlled to perform work through the controller 110 provided in the charging port system, and the first driving device 131 can be used to drive the outer cover 122 to perform the opening action. After the outer cover 122 is opened, the above-mentioned controller 110 can continue to control the second driving device 132 to perform work, and the second driving device 132 can drive the inner cover 121 to perform the opening action. That is to say, after the outer cover 122 is opened, the inner cover 121 can be opened immediately, forming a linkage opening mode of the outer cover 122 and the inner cover 121. When the outer cover 122 and the inner cover 121 are all opened, the charging port is open. state.

After the charging port is opened, external charging equipment such as a charging plug is inserted into the charging port to charge the electric vehicle and provide energy. After charging is completed, if the charging port needs to be closed, the embodiment of the present disclosure is designed to control the inner cover 121 to close first through the second driving device 132, and then control the outer cover 122 to close through the first driving device 131.

When the inner cover 121 and the outer cover 122 are closed, the charging port is in a closed state, which can protect the charging port.

In the embodiment of the present disclosure, the controller 110 may be installed in a vehicle, for example, and the controller 110 may interact with the entire electric vehicle through a CAN line. The controller 110 can be used to control the first driving device 131 and the second driving device 132 to perform work or stop working.

It should be noted that the above-mentioned controller 110 may be a controller of an electric vehicle, or may be a controller provided separately for the charging port system. This is not limited in the embodiment of the present disclosure.

In some examples of the present disclosure, referring to FIG. 1 , the first driving device 131 is configured with a detection module 140 , and the detection module 140 is used to detect the driving state of the outer cover 122 by the first driving device 131 , The charging port system can determine whether the outer cover 122 moves to the open position through the detection module 140 .

Optionally, the detection module 140 may be a Hall sensor, for example.

In the charging port system of the embodiment of the present disclosure, when the charging port needs to be opened, the first driving device 131 first drives the outer cover 122 to open, and during the process of opening the outer cover 122, the Hall sensor can detect the first driving device in real time. The current of 131 is used to obtain the driving state of the outer cover 122 by the first driving device 131, and then the charging port system can determine one of the following two situations:

The first situation: the outer cover 122 moves to the open position, and the outer cover 122 has been opened normally;

The second situation: the outer cover 122 has not moved to the open position, and the outer cover 122 may not have been opened or not fully opened. At this time, it can be considered that the outer cover 122 has not been opened normally.

Since the opening of the outer cover 122 and the inner cover 121 is designed in a linked manner in the solution of the present disclosure, using the detection module 140 to determine whether the outer cover 122 moves to the open position can be a prerequisite for determining whether to open the inner cover 121 . It is also beneficial to realize the linkage control sequence of the outer cover 122 and the inner cover 121.

It can be understood that, after the charging port system determines that the outer cover 122 has been opened normally, it will continue to control the second driving device 132 to operate, and the second driving device 132 drives the inner cover 121 to open. The opening of the outer cover 122 and the inner cover 121 is interlocked.

It should be noted that the outer cover 122 can be moved to the open position, for example, to a position where the outer cover 122 will not block or hinder the opening of the inner cover 121 after being opened. The specific open position can be flexibly set according to needs, and this is not done in this disclosure. limit.

In practical applications, the detection module 140 can be used to realize the linkage triggering effect of the first driving device 131 and the second driving device 132 . The detection module 140 may be, for example, a Hall sensor, which may be installed on the first driving device 131 or connected to the first driving device 131 .

In an embodiment of the present disclosure, the controller 110 in the charging port system can perform the following control method:

The position of the outer cover 122 detected by the detection module 140 is obtained. If the outer cover 122 is in the open position, the second driving device 132 is controlled to operate. That is, the controller 110 in the charging port system first fully opens the outer cover 122 to the open position, and then opens the inner cover 121 .

That is to say, when the detection module 140 detects that the outer cover 122 is opened to the open position, the detection result can be fed back to the controller 110 , and the controller 110 can control the operation only after receiving the result that the outer cover 122 is opened to the open position. The second driving device 132 enters operation to control the inner cover 121 to open.

It can be understood that when the outer cover 122 is opened to the open position, the driving of the outer cover 122 is stopped. At this time, the inner cover 121 can be driven and controlled to open. That is to say, the prerequisite for driving the inner cover 121 to open is that the outer cover 122 has been fully opened under the control of the controller 110 .

When both the outer cover 122 and the inner cover 121 are opened, the charging port can be exposed, so that charging can be performed.

In some examples of the present disclosure, the charging port system, see FIG. 1 , further includes a position switch 150 , the position switch 150 is used to be provided on an electric vehicle, and when the outer cover 122 moves to the closed position, the position switch 150 is triggered. The position switch 150; the charging port system is configured to check whether the outer cover 122 moves to the closed position through the position switch 150.

Optionally, a position switch 150 may be installed in the closed position of the outer cover 122 . The position switch 150 can be used to identify the closing position of the outer cover 122 during the closing process to ensure the gap level difference between the outer cover 122 and the side panel after closing.

Optionally, the position switch 150 can interact with the controller 110 provided on the electric vehicle through a CAN line.

When closing the charging port, both the inner cover 121 and the outer cover 122 need to be closed, but since the outer cover 122 is located at the outermost side, it is particularly important to protect the inner cover 121 and the charging port. Therefore, when closing the charging port, it is necessary to ensure that the outer cover 122 can move to the designated closing position, that is, closed in place.

The outer cover 122 can be moved to the closed position after the outer cover 122 is closed. The outer surface of the outer cover 122 is flush with the outer surface of the electric vehicle body, and the outer cover 122 does not protrude from the surface of the vehicle body.

The position switch 150 is introduced into the charging port system of the embodiment of the present disclosure, and the position switch 150 can be set at the closed position of the outer cover 122 . In this way, when the outer cover 122 is driven by the first driving device 131 to perform the closing action and moves to the closing position, the position switch 150 can be triggered.

If the position switch 150 is not triggered after the outer cover 122 performs the closing action, it means that the outer cover 122 has not moved to the closed position. In this case, the controller 110 in the charging port system can control the outer cover 122 to perform the closing action again until the outer cover 122 moves to the closed position.

That is to say, the charging port system 100 can determine whether the outer cover 122 moves to the closed position after closing based on the signal fed back by the position switch 150, thereby ensuring that the charging port is completely closed. When the outer cover 122 does not move to the closed position, the outer cover 122 needs to be controlled to be closed again until the outer cover 122 can be adjusted to move to the closed position and the outer cover 122 is completely closed. The disclosed charging port system can ensure that the charging port is completely closed to avoid exposure of the charging port.

After controlling the outer cover 122 to be in an open state, the method further includes: determining the closed position of the outer cover 122 based on the position signal detected by the position switch 150 , wherein the position signal carries position information when the outer cover 122 is in the closed position.

Among them, the position switch 150 and the controller 110 can interact through signals to ensure that the outer cover 122 can accurately move to the closed position during the closing process of the charging port, that is, it can ensure that the outer cover 122 can be completely closed without cocked.

If the position switch 150 is not triggered by the outer cover 122 after the outer cover 122 completes the closing action, it means that the outer cover 122 has not moved to the closed position at this time. Then, the controller 110 can control the outer cover 122 to close again until the outer cover 122 moves to the closed position and is closed in place. During this process, the controller 110 can also control to generate an alarm through a meter or a vehicle-mounted speaker to remind the user that the outer cover 122 has not moved to the closed position normally and that corresponding processing needs to be performed. In this way, the person driving the vehicle can intuitively understand the switching status of the charging port.

In some examples of the present disclosure, the charging port system is configured to calibrate the detection module 140 according to the triggering state of the position switch 150 . When the charging port cover 120 is repeatedly opened and closed, the detection module 140 may cause counting errors and signal reference position misalignment. If this phenomenon occurs, the charging port system or the on-board computer cannot accurately determine whether the outer cover 122 has accurately moved to the open position and the closed position through the detection module 140 . In the technical solution equipped with the position switch 150, whether the position switch 150 is triggered can accurately identify whether the outer cover 122 has moved to the closed position. Accordingly, the charging port system can calibrate and reset the reference position or zero position of the detection module 140 according to the position switch 150 . Therefore, the calibrated signal of the detection module 140 can accurately reflect the movement of the outer cover 122 to the open position.

As mentioned above, the detection module 140 can detect whether the outer cover 122 moves to the open position. There are many forms of feedback signals that can be actually used. For example, a Hall sensor can be used to measure the rotation of the first driving device 131. Real-time monitoring; or, use the driving current of the first driving device 131 as a feedback signal to determine whether the first driving device 131 is stalled, etc.

Optionally, the detection module 140 may be configured with a preset signal. This preset signal represents that the outer cover 122 has moved to the open position, and the accurate preset signal can be obtained by actually testing the movement of the outer cover 122 and stored in the system and on-board computer. After determining that the outer cover 122 has moved to the open position, the controller 110 of the charging port system can stop the first driving device 131 and trigger the second driving device 132 to drive the inner cover 121 to move to the open position. In this way, it can be accurately determined whether the outer cover 122 reaches the open position, thereby providing reliability for the accurate linkage of the inner cover 121 and the outer cover 122 .

The movement linkage control of the outer cover 122 and the inner cover 121 can also be realized by monitoring the driving current of the first driving device 131 and the second driving device 132 .

In a specific embodiment, referring to Figure 2, the controller 110 in the charging port system can detect the current driving current I1 of the first driving device 131, if it is lower than a first set threshold (the first set threshold can be, for example When the value is the locked-rotor threshold of the motor), it means that the outer cover 122 can move normally, and the outer cover 122 can be controlled to open to the open position. After the outer cover 122 is opened to the open position, the charging port system can control the opening of the inner cover 121 , that is, steps S210 to S220.

Specifically, the charging port system controls the operation of the second driving device 132 and obtains the driving current of the second driving device 132 when the second driving device 132 is operating. Subsequently, it can be determined based on the driving current whether the inner cover 121 has been opened, that is, whether it is in the open position.

Optionally, the first driving device 131 is an outer cover driving motor, and the second driving device 132 is an inner cover driving motor. In this way, automatic switching of the charging port can be realized.

In the embodiment of the present disclosure, the controller 110 of the charging port system can also be used to control the second driving device 132 to perform work or stop working.

In the embodiment of the present disclosure, a driving current threshold can be set for the second driving device 132, that is, the above-mentioned second set threshold I20.

It should be noted that the second set threshold I20 may be close to or equal to the stall threshold of the second driving device 132 (in order to distinguish the stall threshold of the first drive device, here it is also the second stall threshold). Usually the second set threshold I20 does not exceed the stall threshold to protect the second driving device 132 .

In a specific embodiment, when the second driving device 132 is working, the driving current I2 in its current working state can be detected by the controller 110 of the charging port system, see step S230 in FIG. 2 .

After the controller 110 obtains the current driving current I2 of the second driving device 132, execute:

Step S240: When the driving current I2 of the second driving device 132 reaches the second set threshold I20, control the inner cover 121 to move to the open position.

As mentioned above, the second set threshold I20 may be close to but not exceed the blocking threshold of the second driving device 132, This can be used as a basis for the controller 110 to determine whether the inner cover 121 has been opened.

When the controller 110 of the charging port system detects that the driving current of the second driving device 132 in the working state reaches the second set threshold I20, it indicates that the inner cover 121 driven by the second driving device 132 has moved to the open position and can no longer be opened. Continue the movement, that is, the inner cover 121 has been completely opened. At this time, the controller 110 needs to control the second driving device 132 to stop, and the second driving device 132 stops driving the inner cover 121 to continue opening.

That is to say, when the controller 110 detects that the inner cover 121 has been completely opened, it controls the second driving device 132 to stop working, thereby stopping further opening of the inner cover 121 .

Among them, in order to prevent damage to the second driving device 132 and affect the service life of the second driving device 130, the second set threshold I20 is designed to be close to but not exceeding the rotor blocking threshold of the second driving device 132.

When the controller 110 detects that the current driving current I2 of the second driving device 132 is lower than the above-mentioned second set threshold I20, it may indicate that the inner cover 121 has not been opened at this time or has only been partially opened. In this case down, the inner cover 121 can be continued to be driven to open.

After the inner cover 121 is also opened, both the outer cover 122 and the inner cover 121 of the charging port cover 120 are in the open position. Optionally, the charging port system can maintain the charging port in an open position for a certain period of time.

In a specific embodiment, when the controller 110 of the charging port system determines that the inner cover 121 has not moved to the open position and the driving current of the second driving device 132 continues to be lower than the second set threshold I20, the controller 110 can pass The vehicle's instrument or car audio generates an alarm message to remind the user that the inner cover 121 of the current charging port cover 120 cannot move to the open position normally.

According to the embodiments of the present disclosure, through the above technical solutions, the human operation steps can be simplified, and the design of the inner cover 121 and the outer cover 122 of the charging port cover 120 of the electric vehicle can be automatically opened in an electronic manner, because no user is required in the whole process. Manually touching the charging port cover 120 can avoid dirt, which can improve the user's experience and interaction with the electric vehicle. Moreover, since the driving current is reasonably adjusted during the drive control of the outer cover 122 of the charging port cover 120, the outer cover 122 can be controlled to achieve safe opening. It is also relatively simple to determine whether the inner cover 121 has been opened.

Optionally, as mentioned above, when the first driving device 131 is working, the driving current I1 in the current working state can be detected by the controller 110 . As for the first set threshold I10, it may be the locked-rotor threshold of the first driving device 131 (which is a motor) (which may be called the first locked-rotor threshold).

When the controller 110 of the charging port system detects that the driving current of the first driving device 131 in the working state reaches the above-mentioned first set threshold (that is, the first locked-rotor threshold), it indicates that the first driving device 131 When driving the outer cover 122 to perform the opening operation, the outer cover 122 may encounter obstacles. For example, the outer cover 122 is blocked by an external object or is stuck, causing the outer cover 122 to fail to open normally. At this time, the controller 110 needs to control the first driving device 131 to stop, and the opening operation of the outer cover 122 is stopped.
