Description

Technical Field

[0001] The present disclosure relates to a charging port device, a charging method and a vehicle, and belongs to the technical field of charging of electric vehicles. Background Art

[0002] To accommodate both fast and slow charging needs, electric vehicles currently often use a dual-charging port design arranged side by side. To protect the charging ports, a cover is provided. Existing cover structures mostly come in two types. One is to provide a separate cover for each charging port, forming a split structure. Users need to manually identify the charging type and operate the two covers separately to insert the charging gun for charging. The operation steps are cumbersome, especially in fast charging scenarios, which affects the efficiency of use. The other is to use an integral cover, which can be fully opened or closed to simultaneously expose or shield the two charging ports. However, this design leaves the unused charging port completely exposed when one of the charging ports is in use, making it susceptible to intrusion by rain, dust, etc., posing a safety hazard. Summary of the Invention

[0003] In order to solve the above-mentioned technical problems of traditional charging ports, the present disclosure proposes a charging port device, a charging method and a vehicle, which can provide reliable protection for unused charging ports while ensuring operational convenience and can also realize intelligent charging.

[0004] Specifically, the first aspect of the present disclosure proposes a charging port device for an electric vehicle, comprising: a charging port portion, the charging port portion having a first charging port and a second charging port arranged side by side; a cover portion, the cover portion being slidably arranged above the charging port portion, and the cover body of the cover portion being integrally formed with an opening portion and a covering portion, the opening portion having a size that completely exposes at least the larger one of the first charging port and the second charging port, and the covering portion having a size that completely covers at least the larger one of the first charging port and the second charging port; and a driving portion, the driving portion driving the cover portion to slide relative to the charging port portion so that the cover portion switches between a first position and a second position, wherein, in the first position, the first charging port is completely exposed through the opening portion and the second charging port is completely covered by the covering portion, and in the second position, the first charging port is completely covered by the covering portion and the second charging port is completely exposed through the opening portion.

[0005] According to the charging port device with the above configuration, the opening portion and the covering portion are integrated in a single cover portion. Compared with the design of the dual charging ports being respectively configured with independent cover bodies in the prior art, the number of movable parts is effectively reduced and the overall structure is simplified. The cover portion can be automatically controlled by the driving portion and can realize the switching between the first position and the second position by a simple sliding operation, replacing the manual operation of the cover body. It not only improves the convenience of operation, but also ensures the smoothness and position accuracy of the sliding process of the cover portion through controllable driving force, and reliably realizes the effect of "when one charging port is in use, the other charging port is in a completely shielded state" in an intelligent manner, effectively preventing the unused charging port from being exposed to the external environment and the risk of foreign matter intrusion, electric shock, etc., while simplifying the structure, taking into account the safety, reliability and automation during the use of the dual charging ports.

[0006] Preferably, the charging port device of the first aspect further includes: a guiding mechanism, wherein the guiding mechanism includes a guide rail provided on one of the charging port portion and the cover portion and a slider provided on the other thereof, wherein the guide rail and the slider cooperate with each other and can slide relative to each other, thereby guiding the sliding of the cover portion relative to the charging port portion.

[0007] According to the charging port device with the above configuration, the guide mechanism composed of the guide rail and the slider can constrain the sliding trajectory of the cover relative to the charging port, effectively limit the lateral deviation and shaking of the cover during the sliding process, ensure that the cover always moves smoothly in the preset direction, and avoid the sliding jam or stagnation caused by the deviation of the cover body. Moreover, by using this guide mechanism, the contact friction of the cover during sliding mainly exists in the guide rail and the slider, which reduces the contact friction area of ​​the cover during sliding, reduces the sliding resistance, and enables the cover to achieve position switching more smoothly under the action of the drive unit, reducing energy loss during the driving process. In addition, the structural combination of the guide rail and the slider can also disperse the external force such as vehicle vibration on the cover, avoid external force directly acting on the connection position between the cover body and the drive unit, thereby reducing the risk of component deformation or damage, and ensuring the reliability and stability of the long-term sliding movement of the cover.

[0008] Preferably, in the charging port device of the first aspect, a drainage groove is integrated inside the guide rail, so that water entering the inside of the guide rail is led out to the outside through the drainage groove.

[0009] According to the charging port device with the above configuration, the drainage groove is used. Even when water or other liquids accidentally enter the inner side of the guide rail, the drainage groove can collect and guide the liquid to the outside, avoiding the liquid from being retained in the fitting gap between the guide rail and the slider, avoiding accumulated water and increasing the sliding resistance of the cover, and effectively avoiding the risk of liquid seeping into the charging port and causing circuit short circuit or poor contact, thereby improving the reliability of the device in humid or rainy environments.

[0010] Preferably, the charging port device of the first aspect further includes: an annular outer sealing portion, which is arranged on the periphery of the cover body of the cover portion, and is attached between the cover body and the panel of the charging port portion and seals; and / or an inner sealing portion, which is arranged on the covering portion of the cover portion, and includes a first sealing portion arranged on one side of the opening portion and a second sealing portion arranged on the other side of the opening portion, when the cover portion is in the first position, the second sealing portion faces the covered second charging port to seal the second charging port, and when the cover portion is in the second position, the first sealing portion faces the covered first charging port to seal the first charging port.

[0011] According to the charging port device with the above configuration, the waterproof and dustproof performance can be further improved by providing a sealing part. The annular outer sealing part is fitted between the periphery of the cover body and the charging port panel, which can effectively prevent external water, dust and other impurities from invading the interior of the device through the gap between the cover and the panel, forming a first sealing barrier; the inner sealing part can fit with an unused charging port regardless of whether the cover is in the first position or the second position, ensuring that the unused charging port is always in a closed state, preventing water and dust from directly contacting the conductive components inside the charging port, and reducing the risk of short circuits and poor contact caused by impurity intrusion. The outer sealing part and the inner sealing part form a multi-level protection from the overall gap to the local charging port, significantly improving the waterproof and dustproof performance of the device, and ensuring the safety and durability of the charging port in complex environments.

[0012] Preferably, in the charging port device of the first aspect, the driving portion includes: a motor; and a transmission mechanism connected between the motor and the cover portion, the transmission mechanism converts the rotational driving force of the motor into a sliding driving force of the cover portion and transmits it to the cover portion.

[0013] According to the charging port device having the above configuration, the drive unit uses a motor as a power source, capable of providing a stable and controllable rotational driving force. This allows the sliding speed and travel of the cover to be precisely controlled by the motor's output parameters, such as speed and direction of rotation. This ensures the positioning accuracy of the cover when switching between the first and second positions, avoiding excessive slippage or misalignment. The transmission mechanism converts the rotational motion into the sliding driving force required by the cover, achieving precise conversion of power forms and ensuring that the cover can slide smoothly along a preset trajectory. Furthermore, the transmission mechanism can adjust the power transmission efficiency to match the motor's output torque with the driving force required for the cover to slide, resulting in a smoother sliding motion of the cover.

[0014] Preferably, in the charging port device of the first aspect, a first locking portion is activated when the cover reaches the first position to lock the cover relative to the charging port; and a second locking portion is activated when the cover reaches the second position to lock the cover relative to the charging port.

[0015] According to the charging port device with the above configuration, the first locking portion and the second locking portion can be used to fix the cover at the target position, effectively preventing the cover from being displaced in the non-operating state, avoiding exposure of the charging port or sealing failure due to displacement of the cover, and preventing the alignment deviation between the opening and the charging port from affecting the normal insertion of the charging gun, thereby significantly improving the structural stability and functional reliability of the device in both use and non-use states.

[0016] Preferably, in the charging port device of the first aspect, the first locking part and the second locking part are constructed in the following manner: Method 1: a locking hole is provided on the cover, an electromagnetic latch and a spring are provided on the panel of the charging port, when the electromagnetic latch is energized, it overcomes the elastic force of the spring and extends from the panel and is inserted into the locking hole to lock, when the power is off, the spring resets to make the electromagnetic latch disengage from the locking hole to unlock; or Method 2: a pair of electromagnets are provided on the cover and the panel, when the power is on, opposite poles attract each other to lock, and when the power is off, the magnetic force disappears to unlock; or Method 3: an electromagnet is provided on one of the cover and the panel and a metal sheet is provided on the other, when the power is on, the electromagnet attracts the metal sheet to lock, and when the power is off, the magnetic force disappears to unlock.

[0017] According to the charging port device with the above configuration, the first locking part and the second locking part can be constructed in three different ways according to needs, ensuring that the cover is reliably fixed when it reaches the first position or the second position. These three methods can all be automatically controlled by electromagnetic means, forming a linkage with the action of the driving part, and can be quickly released when the position of the cover needs to be switched, ensuring smooth execution of the sliding action, thereby improving the locking reliability while taking into account the convenience of operation and the durability of the structure.

[0018] Preferably, the charging port device of the first aspect further includes: a charging type acquisition unit, which acquires whether the charging type to be performed by the charging port device is the first charging type using the first charging port or the second charging type using the second charging port, and the cover switches between the first position and the second position based on the charging type acquired by the charging type acquisition unit.

[0019] According to the charging port device with the above configuration, by configuring the charging type acquisition part, it can automatically identify whether the upcoming charging type is the first charging type or the second charging type, and drive the cover to accurately switch between the first position and the second position accordingly, which significantly improves the intelligence level and operation convenience of the device. It eliminates the need for the user to manually determine the charging type and operate the cover. Instead, the position switching is completed by automatically acquiring the charging type information and directly linking the cover, which reduces the user's operating steps and effectively improves the charging efficiency and usage experience.

[0020] The second aspect of the present disclosure provides a charging method using the charging port device described in the first aspect, including: receiving a signal about the charging type; in response to the signal, the driving part of the charging port device operates so that the cover is in a first position or a second position corresponding to the charging type; and receiving an external charging device through the exposed first charging port or the second charging port to achieve charging.

[0021] A third aspect of the present disclosure provides a vehicle, comprising the charging port device according to the first aspect.

[0022] The charging method of the second aspect and the vehicle of the third aspect of the present disclosure can also achieve the technical effects of the first aspect mentioned above accordingly due to the adoption of the charging port device of the first aspect, significantly improving the overall intelligent experience and utilization efficiency of electric vehicle charging, and improving the customer satisfaction and competitiveness of the vehicle.

[0061] Hereinafter, the technical solutions of the present invention will be more clearly explained by describing specific embodiments of the present invention with reference to the accompanying drawings.

[0062] It should be noted that the drawings in the present invention are merely schematic diagrams for the purpose of clearly illustrating the parts related to the solutions of the present invention, and do not show some non-essential parts that may exist. Therefore, these drawings should not be understood as limiting the present invention, and they may differ from the actual structure when used. In addition, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", etc. that may appear in the following description to indicate direction or position are for the purpose of convenience of explanation and are not restrictive. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0063] <First embodiment>

[0064] Figures 1-9 A charging port device 1 according to a first embodiment of the present disclosure is shown.

[0065] First, refer to Figure 1 and Figure 2 The charging port portion 10 of the charging port device of this embodiment is described, wherein: Figure 1 is a schematic plan view of the charging port portion 10 of the charging port device 1 of this embodiment; Figure 2 yes Figure 1 AA cross-sectional view.

[0066] like Figure 1 and Figure 2As shown, the charging port portion 10 is provided on the body of a charging vehicle or a hybrid vehicle, for example, to receive power from an external charging device, such as a charging gun of a charging pile, so as to charge. The charging port portion 10 has a first charging port 12 and a second charging port 13 arranged side by side, which are respectively recessed from the panel 11. In this embodiment, the first charging port 12 is described as a DC charging port suitable for fast charging, and the second charging port 13 is described as an AC charging port suitable for ordinary charging. Terminals are provided inside the first charging port 12 and the second charging port 13, which can cooperate with and conduct with the matching terminals of the corresponding charging guns to receive power.

[0067] Because the charging port portion 10 has two charging ports, a first charging port 12 and a second charging port 13, if one of the charging ports is in use and the other is unused, if the unused charging port is exposed to rain or dust, there is a high risk of a short circuit. The prior art circumvents this risk by providing a flap that is manually opened and closed. However, the flap operation steps in the prior art are cumbersome and affect efficiency.

[0068] The charging port device 1 of this embodiment is provided with Figure 3 and Figure 4 The cover 20 shown can provide reliable protection for unused charging ports while ensuring convenient operation, and can also achieve intelligent charging.

[0069] The cover 20 of the charging port device 1 is a sliding cover that is slidably positioned above the charging port 10. The cover body 21 of the cover 20 integrally forms an opening 22 and a covering portion 23. The opening 22 is sized to fully expose at least the larger of the first and second charging ports 12, 13 (in this embodiment, the first charging port 12, which serves as a DC charging port), while the covering portion is sized to fully cover at least the larger of the first and second charging ports 12, 13. By utilizing a single sliding cover to form the cover 20, the charging port can be opened and closed by sliding, eliminating the need for additional rotation or flipping space required by traditional flip covers, thus saving installation space.

[0070] In order to enable the cover 20 of the charging port device 1 to automatically slide without manual operation, Figure 5As shown in FIG. 1 , the charging port device 1 further includes a drive unit 30 disposed between the charging port 10 and the cover 20. In this embodiment, the drive unit 30 includes a motor 31 and a transmission mechanism 32 connected between the motor 31 and the cover 20. The transmission mechanism 32 converts the rotational drive force of the motor 31 into a sliding drive force for the cover 20 and transmits it to the cover 20. The motor 31 may be a built-in micro-stepping motor with a certain waterproof rating, such as IP67.

[0071] By driving the driving unit 30, the cover 20 slides relative to the charging port 10, so that the cover 20 can Figure 5 The first position and Figure 7 Switches between the second positions shown. Figure 5 In the first position shown, the first charging port 12 is completely exposed through the opening 22 and the second charging port 13 is completely covered by the cover 23. Figure 7 In the second position shown, the first charging port 12 is completely covered by the cover 23, and the second charging port 13 is fully exposed through the opening 22. Because the dimensions of the opening 22 and the cover 23 are based on the larger of the first and second charging ports 12, 13, the required charging port is fully exposed and unused charging ports are fully covered in both the first and second positions, allowing a single cover to universally accommodate dual charging ports of different specifications.

[0072] The transmission mechanism 32 may be a worm gear, a gear rack, a lead screw nut, a conveyor belt, etc. A reduction gear may also be provided on the transmission path.

[0073] The drive unit 30 uses the motor 31 as a power source to provide a stable and controllable rotational driving force, so that the sliding speed and stroke of the cover 20 can be accurately controlled by the output parameters of the motor 31, such as the speed and direction, thereby ensuring the positioning accuracy of the cover 20 when switching between the first position and the second position, and avoiding excessive slippage or failure to reach the position. The rotational motion of the motor 31 is converted into the sliding driving force required by the cover 20 through the transmission mechanism 32, which can achieve accurate conversion of the power form and ensure that the cover 20 can slide smoothly along the preset trajectory. In addition, the transmission mechanism 32 can also adjust the power transmission efficiency (for example, by adjusting the gear ratio) to match the output torque of the motor 31 with the driving force required for the sliding of the cover 20, so that the sliding motion of the cover 20 is smoother.

[0074] As described above, in the charging port device 1 of the present embodiment, the opening portion 22 and the covering portion 23 are integrated into a single cover portion 20. Compared with the design in the prior art in which two charging ports are respectively equipped with independent flip covers, the number of moving parts is effectively reduced and the overall structure is simplified. The cover portion 20 can be automatically controlled by the driving portion 30 and can achieve switching between the first position and the second position by a simple sliding operation, replacing the manual operation of the cover body. It not only improves the convenience of operation, but also ensures the smoothness and position accuracy of the sliding process of the cover portion 20 through controllable driving force, and reliably realizes the effect of "when one charging port is in use, the other charging port is in a completely shielded state" in an intelligent manner, effectively preventing the unused charging port from being exposed to the external environment and the risk of foreign matter intrusion, electric shock, etc., while simplifying the structure, taking into account the safety, reliability and automation during the use of the dual charging ports.

[0075] like Figure 1 and Figure 9 As shown, in the charging port device 1 of this embodiment, a guide mechanism is also provided. In this embodiment, the guide mechanism includes: two guide grooves provided on the panel 11 of the charging port portion 10, serving as the guide rails 14 of this embodiment; and a ball bearing provided on the cover body 21 of the cover portion 20, serving as the slider 24 of this embodiment. The two guide rails 14 are provided in a manner of sandwiching the first charging port 12 and the second charging port 13, and extend along the sliding direction. The raceway surface of the guide rail 14 can be made of stainless steel, thereby having better support force and wear resistance. The slider 24 is provided at a position corresponding to each guide rail 14, and can be provided in multiple numbers at intervals along the sliding direction. The slider 24 fits in the guide rail 14 and moves along the guide rail 14 to achieve sliding guidance of the cover portion 20 relative to the charging port portion 10.

[0076] The guide mechanism formed by the guide rail (guide groove) 14 and the slider (ball bearing) 24 constrains the sliding trajectory of the cover 20 relative to the charging port 10, effectively limiting lateral deviation and shaking of the cover 20 during sliding, ensuring that the cover 20 always moves smoothly in the preset direction and avoiding sliding jams or stagnation caused by cover body deviation. Furthermore, with this guide mechanism, the contact friction of the cover during sliding mainly occurs through rolling friction between the guide rail 14 and the slider 24. This reduces the contact friction area during sliding of the cover 20 and lowers the sliding resistance, allowing the cover 20 to switch positions more smoothly under the action of the drive unit 30 and reducing energy loss during the driving process. Furthermore, the structural combination of the guide rail 14 and the slider 24 disperses external forces, such as vehicle vibration, on the cover 20, preventing external forces from directly acting on the connection between the cover body 21 and the drive unit 30. This reduces the risk of component deformation or damage and ensures the reliability and stability of the long-term sliding movement of the cover 20.

[0077] Next, the waterproof design further implemented on the charging port device 1 of this embodiment will be described.

[0078] like Figure 4 、 Figure 6 and Figure 8 As shown, in order to further improve the waterproofness (and at the same time improve the dustproofness), the charging port device 1 of this embodiment is configured with a sealing portion 40. The sealing portion 40 includes: an annular outer sealing portion 41, which is provided at the periphery of the cover body 21 of the cover 20, and is attached between the cover body 21 and the panel 11 of the charging port 10 and seals; and an inner sealing portion 42, which is provided at the covering portion 23 of the cover 20, and includes a first sealing portion 43 provided on one side of the opening 22 and a second sealing portion 44 provided on the other side of the opening 22. When the cover 20 is in the first position ( Figure 6 ), the second sealing portion 44 faces the covered second charging port 13 to seal the second charging port 13. When the cover 20 is in the second position ( Figure 8 ), the first sealing portion 43 faces the covered first charging port 12 to seal the first charging port 12.

[0079] The outer sealing portion 41 and the inner sealing portion 42 may be made of TPU (Thermoplastic Polyurethane) material, which has excellent high elasticity and wear resistance.

[0080] The charging port device 1 of this embodiment further enhances its waterproof and dustproof performance by providing a sealing portion 40. The annular outer sealing portion 41, which fits between the periphery of the cover body 21 and the panel 11 of the charging port 10, effectively blocks external impurities such as water and dust from entering the device through the gap between the cover 20 and the panel 11, forming a primary sealing barrier. The inner sealing portion 42, whether the cover 20 is in the first or second position, fits against an unused charging port, ensuring that the unused charging port remains sealed. This prevents water and dust from directly contacting the conductive components within the charging port and reduces the risk of short circuits and poor contact caused by impurities. The outer and inner sealing portions 41 and 42 form a multi-layered protection system, extending from the overall gap to the localized charging port, significantly enhancing the device's waterproof and dustproof performance and ensuring the safety and durability of the charging port device 1 in complex environments.

[0081] In addition to the sealing portion 40, the charging port device 1 of this embodiment may also integrate a drainage groove (not shown) inside the guide rail 14, allowing liquids entering the guide rail 14 to be drained to the outside through the drainage groove. Therefore, even if water or other liquids accidentally enter the guide rail 14, the drainage groove can collect and direct the liquid to the outside, preventing the liquid from being retained in the clearance between the guide rail and the slider, preventing water accumulation from increasing the sliding resistance of the cover, and effectively preventing the risk of liquid seeping into the charging port and causing circuit shorts or poor contact, thereby improving the reliability of the device in humid or rainy environments.

[0082] The charging port device 1 of this embodiment is also provided with a first locking portion and a second locking portion. The first locking portion is activated when the cover 20 reaches the first position, locking the cover 20 relative to the charging port 10; the second locking portion is activated when the cover 20 reaches the second position, locking the cover 20 relative to the charging port 10. Utilizing the first and second locking portions, the cover 20 can be fixed in the target position, effectively preventing displacement of the cover 20 when not in operation. This not only avoids exposure of the charging port or sealing failure caused by displacement of the cover 20, but also prevents misalignment between the opening 22 and the charging port from affecting the normal insertion of the charging gun, significantly improving the structural stability and functional reliability of the device in both use and non-use states.

[0083] Specifically, such as Figure 1 、 Figure 3 、 Figure 5 and Figure 7 As shown, an electromagnetic latch 53 is provided on the panel 11 of the charging port 10, and a spring (not shown) is sleeved on the outside of the electromagnetic latch 53 or fixed to the electromagnetic latch 53 at one end. Two holes, namely a first locking hole 51 and a second locking hole 52, are provided on the cover body 21 of the cover 20. When not powered, the electromagnetic latch 53 is accommodated in the receiving groove of the panel 11 and the spring (not shown) is in a free state. At this time, due to the accommodated state of the electromagnetic latch 53 (not extending from the panel 11), it does not interfere with the sliding movement of the cover 20. On the other hand, when the cover 20 slides into place, for example, it slides to Figure 5 In the first position shown, the first locking hole 51 is in a position aligned with and overlapped with the electromagnetic latch 53. The electromagnetic latch 53 is energized and, under electromagnetic action, overcomes the elastic force of the spring and extends from the panel 11 and inserts into the first locking hole 51 to lock. The cover 20 is restricted and cannot move in the sliding direction. Similarly, when the cover 20 slides into place, for example, Figure 7 In the second position shown, the second locking hole 52 is in a position aligned and overlapping with the electromagnetic latch 53. The electromagnetic latch 53 is energized so that it overcomes the elastic force of the spring under the action of the electromagnetic force and extends from the panel 11 and is inserted into the second locking hole 52 to lock it. The cover 20 is limited and cannot move in the sliding direction.

[0084] When the cover 20 needs to be slid, the electromagnetic latch 53 is de-energized, and the elastic restoring force of the spring causes the electromagnetic latch 53 to disengage from the first locking hole 51 or the second locking hole 52 to unlock the cover 20, and the cover 20 becomes able to slide again.

[0085] Accordingly, in this embodiment, the first locking portion formed by the first locking hole 51 and the electromagnetic latch 53 and the second locking portion formed by the second locking hole 52 and the electromagnetic latch 53 can fix the cover 20 at the target position, effectively preventing the cover 20 from being displaced in the non-operating state, avoiding exposure of the charging port or sealing failure due to displacement of the cover 20, and preventing the alignment deviation between the opening 22 and the charging port from affecting the normal insertion of the charging gun, thereby significantly improving the structural stability and functional reliability of the device in both use and non-use states.

[0086] Continue to see Figure 1 、 Figure 5 and Figure 7 In the charging port device 1 of this embodiment, a camera 60 is provided on the panel 11 of the charging port portion 10, serving as an example of a charging type detection unit. Camera 60 uses image recognition to determine whether an external charging device, such as a charging gun, is using the first charging type (DC charging in this embodiment) using the first charging port 12 or the second charging type (AC charging in this embodiment) using the second charging port 13. The cover 20 can switch between the first and second positions based on the charging type detected by camera 60.

[0087] Therefore, by configuring a charging type acquisition unit such as a camera 60, it is possible to automatically identify whether the upcoming charging type is the first charging type or the second charging type, and accordingly drive the cover 20 to accurately switch between the first position and the second position, thereby significantly improving the intelligence and operational convenience of the device. The user does not need to manually determine the charging type and operate the cover, but instead automatically obtains the charging type information to directly link the cover to complete the position switching, reducing the user's operating steps and effectively improving the charging efficiency and user experience.

[0088] The configuration of the charging port device 1 according to the first embodiment has been described above with reference to the accompanying drawings. Figure 5-Figure 8 Briefly describe its working scenario.

[0089] When the user intends to charge the vehicle, he or she takes the charging gun and opens the cover of the charging port. At this point, the system recognizes that the cover is open and immediately sends a command to the camera 60 on the charging port unit 10 to enable the camera 60 to identify the type of charging gun. After receiving the charging type information, the system determines whether the target charging port is currently exposed and usable. If the target charging port is in a usable state, no action is taken. If the target charging port is covered and unusable, the drive unit 30 immediately responds, the motor 31 starts, and the transmission mechanism 32 converts the rotational power into a sliding drive force for the cover 20. At the same time, the guide rail 14 of the guide mechanism cooperates with the slider 24 to constrain the cover to slide smoothly along the preset trajectory.

[0090] For example, when the camera 60 identifies that the type of charging gun is a DC charging gun for fast charging, if the system determines that the first charging port 12 is covered and unusable (for example, Figure 8 The cover 20 is in the second position as shown in the figure), at this time, the electromagnetic latch 53 immediately responds to the power off and escapes from the state of being locked with the second locking hole 52, and the cover 20 resumes its sliding ability; at the same time, the driving part 30 immediately responds and activates the cover 20 to slide, so that the cover 20 is Figure 7 、 Figure 8 The second position shown in FIG. 1 is moved to the left until the opening 22 is in the first position above the first charging port 12 and the first charging port 12 is completely exposed. Figure 5 、 Figure 6 At the same time, the cover 23 covers the second charging port 13, and the second sealing portion 44 is located above the second charging port 13 to seal the second charging port 13. The electromagnetic latch 53 is energized and inserted into the first locking hole 51, re-securing the cover 20 relative to the charging port 10. The user can then insert the charging gun into the first charging port 12 for charging.

[0091] The above description describes the cover 20 from Figure 7 、 Figure 8 The second position of Figure 5 、 Figure 6 In the case of sliding from the first position, the cover 20 Figure 5 、 Figure 6 The first position of Figure 7 、 Figure 8 The situation of the second position slipping is similar and will not be repeated here.

[0092] Also, see Figure 1 In order to prevent the camera 60 from being unable to automatically identify the charging type when an unexpected malfunction occurs, a switch button 61 is further provided on the panel 11 of the charging port 10. The user can operate the switch button 61 to automatically switch the cover 20 between the first position and the second position.

[0093] <Second embodiment>

[0094] Figure 10 The second embodiment of the present disclosure is shown in FIG. The second embodiment is substantially the same as the first embodiment, with the only difference being the arrangement of the guide mechanism.

[0095] In the second embodiment, as Figure 10 As shown, the guide rail 14 is changed from a guide groove to a roughly T-shaped guide protrusion, and sliders 24 composed of balls are provided on both sides.

[0096] The guide mechanism of the second embodiment can also achieve the same technical effects as the first embodiment, and because the balls are basically not exposed to the outside compared to the first embodiment, the reliability is higher.

[0097] <Third embodiment>

[0098] The third embodiment of the present disclosure provides a charging method for a charging port device 1, including: step S101, receiving a signal about the charging type; step S102, in response to the signal, the driving unit 30 of the charging port device 1 operates so that the cover 20 is in a first position or a second position corresponding to the charging type; and step S103, receiving an external charging device through the exposed first charging port 12 or the second charging port 13 to achieve charging.

[0099] The charging method of the third embodiment significantly improves the overall intelligent charging experience and efficiency of electric vehicles, and improves customer satisfaction and competitiveness of the vehicles.

[0100] <Fourth embodiment>

[0101] A fourth embodiment of the present disclosure provides a vehicle including the charging port device 1 described in the first embodiment.

[0102] The vehicle of this embodiment can also achieve the various corresponding technical effects of the above-mentioned first embodiment, so that while ensuring operational convenience, it can provide reliable protection for unused charging ports and can also realize intelligent charging, thereby improving the customer satisfaction and competitiveness of the vehicle.

[0103] <Other embodiments>

[0104] In the above embodiment, the first locking portion and the second locking portion are described by taking the example of providing an electromagnetic latch and two locking holes, but this is not restrictive. For example, the number and position of the electromagnetic latch are not limited to the first embodiment, and can be configured as multiple, and can be configured in other positions. The first locking portion and the second locking portion can also be configured in the form of electromagnets, for example, a pair of electromagnets provided on the cover and the panel, the pair of electromagnets generates a magnetic force when power is applied so that the cover is attracted and locked to the panel, and the magnetic force disappears when power is removed, thereby releasing the lock between the cover and the panel; or, for example, an electromagnet provided on one of the cover and the panel, and a metal sheet provided on the other, the electromagnet generates a magnetic force when power is applied and attracts the metal sheet so that the cover is locked to the panel, and the magnetic force disappears when power is removed, thereby releasing the lock between the cover and the panel.

[0105] In other words, as long as the first and second locking parts can be automatically controlled by electromagnetic means and linked to the operation of the drive unit, they can be quickly released when the cover position needs to be switched to ensure smooth sliding. Utilizing such first and second locking parts improves locking reliability while also balancing operational convenience and structural durability.

[0106] In the above embodiment, the charging type acquisition unit is described using a camera as an example, but this is not restrictive. The charging type acquisition unit can also be a Hall sensor, a photoelectric sensor, a Bluetooth interaction module, etc. The Hall sensor can distinguish the charging type by detecting the magnetic field characteristics of the charging gun based on the Hall effect. The photoelectric sensor can identify the charging gun characteristics and distinguish the charging type according to the "on-off state" or "intensity change" of the light signal by emitting a light signal (such as infrared light) and receiving reflected / transmitted light. The Bluetooth interaction module can realize information interaction between the charging gun and the vehicle through Bluetooth wireless communication, and directly obtain the type data of the charging gun. For example, when the vehicle detects that the charging gun is unplugged, the charging type of the unplugged charging gun can be directly obtained.

[0107] In addition, in the above embodiment, the first charging port is described as a DC charging port, and the second charging port is described as an AC charging port. However, the first charging port may be an AC charging port, and the second charging port may be a DC charging port.

[0108] The above specific embodiments do not limit the scope of protection of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may occur depending on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention are intended to be included within the scope of protection of the present invention.
