Description

Technical Field

[0001] This invention belongs to the field of automotive technology. Specifically, this invention relates to a charging port assembly and a vehicle. Background Technology

[0002] Currently, there are significant differences in charging interface standards in the international market. The European Union mandates the implementation of the Combined Charging System 2 (CCS2) standard, which sets out technical requirements for the mechanical structure dimensions, electrical connection methods, communication protocols, and safety protection levels of charging interfaces that differ from the domestic GB / T standard.

[0003] Existing electric vehicle charging port technology has the following shortcomings:

[0004] Insufficient standard compatibility: If domestic automakers directly use the GB / T standard charging port in their exported models, it will be incompatible with European public charging facilities, requiring additional adapters, increasing user costs and reducing charging convenience.

[0005] Low functional integration: Traditional charging ports only meet basic power transmission functions and lack real-time visual feedback on charging status (such as charging progress and fault diagnosis) and intelligent interaction capabilities, making it difficult to meet users' personalized needs and improve the product competitiveness of automobiles.

[0006] This invention provides a charging port assembly, particularly concerning how to improve functional integration. Summary of the Invention

[0007] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention provides a charging port assembly, the purpose of which is to improve functional integration.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a charging port assembly, including a charging port unit and a charging breathing light. The charging port unit includes a mounting panel and a charging port assembly. The charging port assembly and the charging breathing light are disposed on the mounting panel. The charging port assembly integrates an AC charging port and a DC charging port. The charging breathing light is configured to output corresponding light signals to indicate different charging states.

[0009] The charging breathing light has a low-voltage interface at the rear of the mounting panel, from which a low-voltage wiring harness is connected to the body controller; the charging breathing light is controlled by the body controller.

[0013] During the charging and heating process, the charging indicator light remains illuminated in yellow.

[0014] In the event of a charging malfunction, the charging indicator light will remain illuminated in red for a duration of T minutes before turning off. The light will then re-enter the charging illumination state once the vehicle is unlocked again.

[0015] While charging, the charging indicator dynamically adjusts the flashing frequency of the green light according to the current battery SOC value.

[0016] When in charging reservation waiting status, the charging indicator light flashes yellow;

[0017] When charging is complete, and the battery level reaches 100% or a preset threshold while the charging gun remains connected, the charging indicator light remains continuously lit in green.

[0018] The flashing frequency of the charging breathing light when it flashes dark blue is set to 60±1 times / min.

[0019] The provision that, during charging, the charging indicator dynamically adjusts the flashing frequency of the green light according to the current battery SOC value includes:

[0020] When the SOC value is less than 20%, the flashing frequency is 20±1 times / min;

[0021] When the SOC value is between 20% and 80%, the flicker frequency is 15 ± 1 times / min;

[0026] An ambient light sensor is configured to detect ambient light intensity and transmit the signal to the control unit of the charging breathing light;

[0027] An automatic dimming module is communicatively connected to the ambient light sensor and the control unit, and is configured to dynamically adjust the brightness of the charging breathing light according to the ambient light intensity, wherein the ambient light intensity and the brightness of the charging breathing light are positively correlated.

[0028] The charging port unit also includes a dust cover for mounting onto the charging port assembly. The dust cover includes an AC dust cover and a DC dust cover connected to each other. The AC dust cover and the DC dust cover are used to cover the AC charging port and the DC charging port, respectively.

[0029] The charging port assembly also includes an outer trim panel, which is configured to completely cover the edge contour, bolt mounting points and connection gaps of the charging port assembly when closed, so that the outer surface of the charging port assembly forms a continuous and flat visual effect.

[0030] The present invention also provides a vehicle including the aforementioned charging port assembly.

[0031] The charging port assembly of the present invention has the following beneficial effects:

[0032] 1. The charging port assembly integrates an AC charging port and a DC charging port that comply with the EU CCS2 standard, forming a charging port that complies with European standards;

[0033] 2. An outer trim panel component has been added to cover the bolt fixing points, making the charging port present a flat, unified look for the customer, resulting in a more aesthetically pleasing and streamlined appearance;

[0034] 3. Positioning design has been added to both the front and back of the charging port to avoid matching errors with the vehicle body and exterior trim;

[0035] 4. The charging port component is designed on a platform and can meet the needs of different project structures and scenarios by matching different charging port flange panels and lighting modules, which greatly reduces the development cost and cycle of the project.

[0036] 5. It features a long charging breathing light with a corresponding charging breathing strategy. The breathing effect is displayed during charging to indicate the charging status to the user, thus improving the functional integration. Attached Figure Description

[0070] Example

[0071] Firstly, such as Figures 1 to 6 As shown, this embodiment of the invention provides a charging port assembly 1, including an outer trim panel 6, a charging port unit, and a charging breathing light 13. The charging port unit includes a mounting panel 8 and a charging port assembly 9. The charging port assembly 9 and the charging breathing light 13 are disposed on the mounting panel 8. The charging port assembly 9 integrates an AC charging port and a DC charging port that conform to the EU CCS2 standard. The charging breathing light 13 is configured to output corresponding light signals to indicate different charging states.

[0072] Specifically, the charging port assembly 1 serves as a connection unit between the charging pile and the vehicle. Its main function is to charge the entire vehicle through the charging port assembly 1 when the vehicle plug of the charging pile is connected to the charging port unit. The charging port unit, as the most important component, is also the matching base for the exterior trim panel 6 and the charging breathing light 13.

[0073] like Figures 1 to 6 As shown, in this embodiment of the invention, the mounting panel 8 is fixedly mounted on the vehicle side panel 2 by mounting bolts 3. The mounting panel 8 has a rectangular structure with dimensions of 193*160mm. The four corners of the rectangular mounting panel 8 are chamfered, and four mounting holes with a diameter of 7mm are designed on the four corners for the mounting bolts 3 to pass through. The charging port assembly 9 is assembled to the vehicle side panel 2 of the electric vehicle through four fixing points on the mounting panel 8, thereby fixing it to the electric vehicle. At the same time, a first positioning pin 4 is added to the upper and lower parts of the middle side of the four fixing points on the back of the mounting panel 8. The first positioning pin 4 is used to position with the vehicle side panel 2 to reduce matching errors.

[0074] like Figures 1 to 6 As shown, in this embodiment of the invention, the charging port assembly 1 further includes an outer trim panel 6. The outer trim panel 6 is configured to completely cover the edge contour, bolt mounting points, and connection gaps of the charging port assembly 9 when closed, creating a continuous and flat visual effect on the outer surface of the charging port assembly 1. A boss is provided on the mounting panel 8 to match the outer trim panel 6. One boss is provided, and four mounting holes are distributed around the outer perimeter of the boss. After the outer trim panel 6 is installed, it can conceal the bolt fixing points and the boss, resulting in a more aesthetically pleasing appearance. Two positioning slots are provided on the mounting panel 8 to match the second positioning pin 7 provided on the outer trim panel 6. These slots can be used for positioning during the installation of the outer trim panel 6, reducing installation deviation between the mounting panel 8 and the outer trim panel 6.

[0075] like Figures 1 to 6 As shown, in this embodiment of the invention, a connecting post 10 is provided on the boss, and a receiving hole for accommodating the charging port assembly 9 is provided at the center of the boss. The charging port assembly 9 includes a charging bracket, and an AC charging port and a DC charging port are mounted on the charging bracket. The charging bracket is fixedly connected to the connecting post 10 by bolts. The connecting post 10 is provided with bolt holes, and the axis of the connecting post 10 is parallel to the axis of the mounting hole. The length of the connecting post 10 is 52mm. A total of 4 connecting posts 10 are provided, and the 4 connecting posts 10 are distributed in a rectangular shape.

[0076] In this embodiment of the invention, the AC charging port and DC charging port are structurally designed according to the European standard CCS2. The DC charging port refers to a port that can support a charging current of 80A or more, while the AC charging port is mainly a port with a charging current of less than 32A. The front end of the AC charging port is connected to the AC charging gun, and the rear end is connected to the on-board charger. It is used to input AC power from the AC charging pile to the on-board charger, which then converts the AC power to charge the power battery. The front end of the DC charging port is connected to the DC charging gun, and the rear end is directly connected to the power battery of the electric vehicle. It is used to directly output DC power from the DC charging pile to the power battery for charging.

[0077] like Figure 4 As shown in this embodiment of the invention, the charging port assembly 9 is also equipped with an electronic lock 11. During vehicle charging, the electronic lock 11 can lock the connection between the vehicle plug and the charging port assembly 1, ensuring that the charging gun cannot be unplugged during charging, preventing accidental disconnection during charging, and providing anti-theft protection. An emergency pull rope 12 is designed at the tail of the electronic lock 11. In case of locking, the lock can be unlocked by pulling the emergency pull rope 12, preventing the user from being unable to unplug the charging gun after charging is complete.

[0078] like Figure 2 and Figure 5As shown, in this embodiment of the invention, the charging port unit further includes a dust cover 14 for mounting onto the charging port assembly 9. The dust cover 14 serves to prevent dust and water damage and is made of PA66 plastic as the base material. A pull cord 17 is provided on the dust cover 14, with the other end of the pull cord 17 fixedly connected to the mounting panel 8. The dust cover 14 includes an AC dustproof part 15 and a DC dustproof part 16 connected to each other, which respectively cover the AC charging port and the DC charging port. When not charging, the dust cover 14 is mounted on the charging port; when charging, the corresponding dust cover 14 is removed.

[0079] In this embodiment of the invention, the charging breathing light 13 has a low-voltage interface at the rear of the mounting panel 8, and a low-voltage wiring harness is led out from the rear to connect to the body controller; the breathing light is controlled by 5 PWM waves, and the charging breathing light 13 is controlled by the body controller.

[0080] In this embodiment of the invention, the charging breathing light 13 is used to indicate the current charging status, which includes charging preparation status (including charging gun or discharging gun), charging heating status, charging in progress status, charging reservation waiting status, charging completed status, and charging failure status.

[0081] In this embodiment of the invention, the light signal indication of the charging breathing light 13 includes:

[0082] When charging is ready, the charging indicator light 13 flashes in dark blue.

[0083] During the charging and heating process, the charging breathing light 13 remains illuminated in yellow.

[0084] In the event of a charging malfunction, the charging breathing light 13 will remain illuminated in red for a duration of T minutes before turning off, and will re-enter the charging lighting state after the vehicle is disarmed again.

[0085] While charging, the charging breathing light 13 dynamically adjusts the flashing frequency of the green light according to the current battery SOC value.

[0086] When in charging reservation waiting state, the charging breathing light 13 flashes yellow;

[0087] When charging is complete, and the battery level reaches 100% or a preset threshold while the charging gun remains connected, the charging breathing light 13 will remain continuously lit in green.

[0088] In this embodiment of the invention, the flashing frequency of the charging breathing light 13 when flashing in deep blue is set to 60±1 times / min.

[0089] In this embodiment of the invention, when charging is in progress, the charging breathing light 13 dynamically adjusts the flashing frequency of the green light according to the current battery SOC value, including:

[0090] When the SOC value is less than 20%, the flashing frequency is 20±1 times / min;

[0091] When the SOC value is between 20% and 80%, the flicker frequency is 15 ± 1 times / min;

[0092] When the SOC value is between 80% and 95%, the flicker frequency is 12 ± 1 times / min;

[0093] When the SOC value is greater than 95%, the charging breathing light 13 will remain lit in green.

[0094] In this embodiment of the invention, the flashing frequency of the charging breathing light 13 when it flashes yellow is set to 20±1 times / min.

[0095] In this embodiment of the invention, the mounting panel 8 is further provided with:

[0096] An ambient light sensor is configured to detect the ambient light intensity and transmit the signal to the control unit of the charging breathing light 13;

[0097] An automatic dimming module is communicatively connected to the ambient light sensor and the control unit of the charging breathing light 13, and is configured to dynamically adjust the brightness of the charging breathing light 13 according to the ambient light intensity, wherein the ambient light intensity and the brightness of the charging breathing light 13 are positively correlated.

[0098] In this embodiment of the invention, the charging breathing light 13 includes components such as an LED light source module, a light guide plate, and a light-transmitting mask. The LED light source module includes LED beads of at least three colors. The light guide plate is disposed above the LED light source module to uniformly diffuse the light emitted by the LED beads. The light-transmitting mask covers the light guide plate and has a frosted finish to improve light uniformity. The control unit of the charging breathing light 13 is communicatively connected to the vehicle body controller, and the control unit is configured to control the light emission mode of the LED light source module based on the received SOC value and charging status signal.

[0099] An ambient light sensor mounted on mounting panel 8 detects the ambient light intensity in real time and converts the light signal into an electrical signal. The raw signal output by the ambient light sensor is preprocessed and transmitted to the control unit of the charging breathing light 13 in digital signal form. The control unit has a preset correspondence between light intensity and breathing light brightness, following the principle that the higher the ambient light intensity, the brighter the charging breathing light 13; and the lower the light intensity, the lower the brightness. The detected light intensity value is mapped to the corresponding brightness control signal (such as PWM duty cycle) through a linear or nonlinear algorithm (such as a piecewise function), driving the LED light source module to adjust the luminous power. The automatic dimming module can send brightness adjustment commands to the LED light source module. The automatic dimming module dynamically adjusts the brightness according to real-time data, avoiding display abnormalities caused by sudden changes in ambient light, improving display stability, enhancing the prompting effect, and ensuring accurate indication of the charging status to the user.

[0100] In this embodiment of the invention, the light-transmitting mask of the rechargeable breathing light 13 is made of UV-resistant PC material. The outer surface of the light-transmitting mask is coated with a hydrophobic nano-coating with a thickness of 5-10 μm. The surface tension of the hydrophobic nano-coating is less than 20 mN / m, which makes water droplets form a high contact angle on the coating surface, exhibiting a superhydrophobic state. This prevents rainwater, car wash water and other liquids from seeping into the interior of the lamp, protecting precision electronic components from short circuits or corrosion. Moreover, the nano-coating can resist the aging effect of environmental factors such as ultraviolet (UV) radiation and ozone on the light-transmitting mask, improving its service life.

[0101] Secondly, the present invention also provides a vehicle including a charging port assembly 1 with the above-described structure. The vehicle is an electric vehicle, and this charging port assembly 1 can be referred to... Figures 1 to 6 Further details will not be elaborated here.
