Description

Technical Field

[0001] This application relates to the field of energy replenishment hatch technology, and more specifically, to a hatch module for energy replenishment, a hatch module opening control method, and a vehicle. Background Technology

[0002] When various vehicles (such as cars, ships, and aircraft) perform energy replenishment operations (such as refueling, charging, and gas filling), they typically need to expose the energy replenishment port to the external environment through an externally operable cover module. This type of cover module generally includes a base shell fixed to the vehicle body and a cover that can be opened and closed relative to the base shell. The ease and reliability of its opening and closing mechanism directly affects the user experience and safety of the replenishment operation.

[0003] With the development of sensor interaction technology, more and more lid modules are beginning to adopt non-contact or inductive triggering to replace the traditional purely mechanical opening method.

[0004] Taking the automotive field as an example, by detecting changes in the electric field caused by a human body approaching or touching the cover using capacitive electrodes arranged in the cover area, automatic opening or pre-unlocking of the cover can be achieved, improving operational convenience. However, this single capacitive acquisition detection mechanism has obvious environmental adaptability defects: when rainwater, car wash foam, mud splashes, or other conductive liquids adhere to the cover surface, the liquid will also change the electric field distribution on the electrode surface, causing the sensor to be unable to distinguish between human touch and liquid adhesion, thus resulting in false triggering. This problem is particularly prominent in environments subjected to high-pressure washing, heavy rain splashes, or humidity, seriously affecting the reliability of the cover opening and closing function.

[0005] Furthermore, from the perspective of structural layout and waterproof design, existing sensor controller solutions often face the technical contradiction of separating dry and wet zones. Specifically, to achieve effective capacitive proximity detection, electrodes often need to be placed on the outer surface of the cover or near the surface of the wet zone; while the controller body and power supply and communication lines usually need to be placed in the dry zone inside the base housing. This means that the sensor signal lines must pass through the moving parts of the cover or the dry-wet boundary area, which not only increases the complexity of the sealing design and undermines the integrity of independent protection for the dry and wet zones, but also makes the electrical connections on the moving parts prone to wear, aging, or sealing failure under long-term reciprocating motion and vibration, reducing the durability of the system. Summary of the Invention

[0006] This application provides a cover module for energy replenishment, a cover module opening control method, and a vehicle. The cover module centrally arranges the capacitor's sensing electrode and the induction coil within the recessed cavity of the base shell, ensuring all active electronic components requiring power and signal processing are in a protected dry environment. Only a passive metal layer is placed on the connecting parts that move with the cover, completely eliminating the need for electrical wiring between moving parts and the fixed controller, as required in traditional solutions. This fundamentally avoids problems such as wire wear, aging, and sealing failure caused by reciprocating motion, vibration, and environmental corrosion, significantly improving structural reliability. Long-term durability; Simultaneously, utilizing a non-contact connection method where the metal layer and induction coil are arranged opposite each other with a gap in the closed state, when the lid is subjected to external force, the connector causes relative displacement of the metal layer, resulting in a change in the sensing signal. This achieves the detection of the lid's force state without relying on contact pressure sensors. Combined with the recognition of external conductor proximity or touch by the capacitive acquisition electrode, a composite judgment basis of capacitive proximity and force deformation is formed. This effectively distinguishes between valid human touch and unexpected interference such as rain splashes, liquid adhesion, and foreign object contact, significantly improving the accuracy of trigger recognition and environmental immunity. Specifically: The first aspect of this application provides a cap module for energy replenishment, the cap module comprising: The base shell has a cavity, and the bottom of the cavity is provided with an energy supply port. The cover is movably disposed at the cavity opening position via a connector, and is used to open or close the cavity. The connector is provided with a metal layer. The capacitive sensing electrode is located inside the cavity and is used to detect the approach or touch of an external conductor. An induction coil is located inside the cavity; When the lid is closed, the metal layer is opposite to the induction coil with a gap between them. When the lid is subjected to external force, the connector can also drive the metal layer to move relative to the induction coil, so that the induction coil generates a change in the induction signal.

[0007] In the above technical solution, the capacitor acquisition electrode extends along the inner side of the cavity opening edge.

[0008] In the above technical solution, the capacitor acquisition electrode includes a copper wire arranged around the inside of the cavity opening.

[0009] In the above technical solution, the cap module also includes: The circuit board assembly is located inside the cavity. The connector has a moving plane during the movement of the cover. The circuit board assembly has a mounting surface parallel to the moving plane of the connector. The induction coil is located on the mounting surface of the circuit board assembly and is electrically connected to the circuit board assembly.

[0010] In the above technical solution, the circuit board assembly is used to collect the capacitance change signal value of the capacitor acquisition electrode and the induction signal change value of the induction coil, and to determine whether the cover has been effectively triggered based on the capacitance change signal value and the induction signal change value, so as to output the corresponding control signal.

[0011] In the above technical solution, the connector includes a rotating shaft and a cantilever connected to the rotating shaft, the cover is supported by the cantilever, and the metal layer is disposed on the cantilever.

[0012] In the above technical solution, the metal layer is a thin metal sheet attached to the surface of the connector or a conductive plating layer formed on the surface of the connector.

[0013] A second aspect of this application provides an opening control method for a cover module, applied to the aforementioned cover module. The opening control method includes: Acquire the capacitance change signal value of the capacitor acquisition electrode and the induced signal change value of the induction coil; Based on the changes in capacitance and sensing signals, determine whether the cover has been effectively triggered. When a valid trigger is detected, the control panel opens.

[0014] In the above technical solution, the determination of whether a valid trigger exists based on the capacitance change signal value and the induced signal change value includes: Determine whether the capacitance change signal value reaches the first preset threshold. When the capacitance change signal reaches the first preset threshold, collect and determine whether the sensing signal change value reaches the second preset threshold. When the sensing signal change value reaches the second preset threshold, determine that the cover has a valid trigger. Conversely, if the cover is not triggered, it is determined that there is an invalid trigger.

[0015] A third aspect of the embodiments of this application provides a means of transportation. The vehicle includes the vehicle body and the aforementioned hatch module. The hatch module is installed on the vehicle body, and the energy supply port is used to connect the interior of the vehicle body with external energy supply equipment. or The vehicle uses the opening control method of the aforementioned cover module.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In this embodiment, the cap module centrally arranges the capacitor's acquisition electrode and the induction coil inside the recessed cavity of the base shell. This ensures that all active electronic components requiring power and signal processing are in a protected dry environment, while only a passive metal layer is placed on the connector that moves with the cap. This completely eliminates the need for electrical wiring between the moving parts and the fixed controller, as required in traditional solutions. This fundamentally avoids problems such as wire wear, aging, and sealing failure caused by reciprocating motion, vibration, and environmental corrosion, significantly improving structural reliability and long-term durability. Simultaneously, the metal layer and the induction coil... The coils are arranged in a non-contact manner with a gap between them when they are in the off state. When the cover is subjected to an external force, the connector causes the metal layer to move relative to each other, which causes a change in the sensing signal. This allows the detection of the force state of the cover without relying on a contact pressure sensor. Combined with the recognition of the proximity or touch of an external conductor by the capacitive acquisition electrode, a composite judgment basis of capacitive proximity and force deformation is formed. This can effectively distinguish between valid human touch and unexpected interference such as rain splash, liquid adhesion, and foreign object contact, which greatly improves the accuracy of trigger recognition and the ability to resist environmental interference.

[0025] Example like Figures 1-4 As shown, this application embodiment provides a cover module for energy replenishment. The cover module can be installed on the body of a vehicle (such as a car, ship, aircraft, etc.) to cover or expose the energy replenishment port (such as a charging port, refueling port, etc.) of the vehicle body, and realizes automatic opening control of the cover 10 through sensor interaction.

[0026] The cover module includes a base shell (not shown in the figure), a cover 10, a capacitor acquisition electrode 40, an induction coil 60, and a circuit board assembly 70.

[0027] The base shell has a recessed cavity, and an energy supply port is located at the bottom of the cavity. The base shell can be fixed to the vehicle's body sheet metal by means of fasteners or snap-fit ​​structures, so that the energy supply port is connected to the energy storage device inside the vehicle (such as a battery pack, fuel tank, etc.). The cavity opening faces the outside of the vehicle body, and a dry and wet boundary is formed between the inside of the cavity opening and the inside of the vehicle body. The inner wall surface and bottom area of ​​the cavity constitute the dry area, while the outer side of the cavity opening and the outer surface of the cover 10 are exposed to the external environment, constituting the wet area.

[0028] The cover 10 is movably disposed at the opening of the cavity via a connector, for opening or closing the cavity. In this embodiment, the connector includes a rotating shaft 20 and a cantilever 30 connected to the rotating shaft 20. The cover 10 is supported by the cantilever 30, which is rotatably connected to the base housing via the rotating shaft 20, allowing the cover 10 to perform a flipping opening and closing action around the rotating shaft 20. When the cover 10 is in the closed state, the cover 10 covers the opening of the cavity; when the cover 10 is in the open state, the cover 10 flips around the rotating shaft 20, exposing the energy supply port to the outside.

[0029] A metal layer 50 is provided on the connector. In this embodiment, the metal layer 50 is a thin metal sheet attached to the surface of the cantilever 30 or a conductive plating layer formed on the surface of the cantilever 30. The metal layer 50 is a passive metal layer, that is, the metal layer 50 is not electrically connected to any detection circuit or control circuit, and is only used as a passive target for electromagnetic induction. This passive design eliminates the need for any electrical wiring on the connector and the movable parts of the cover 10, completely avoiding cable connection and sealing issues between the movable parts and the fixed base.

[0030] The capacitive sensing electrode 40 is located inside the cavity, specifically extending along the inner edge of the cavity opening. In this embodiment, the capacitive sensing electrode 40 includes a copper wire (or copper foil trace) surrounding the inner edge of the cavity opening. The capacitive sensing electrode 40 is used to detect the approach or touch of an external conductor. When an external conductor (such as a human finger) approaches or adheres to the outer surface of the cover 10, a coupling capacitor is formed between the conductor and the capacitive sensing electrode 40 through the dielectric of the cover 10, causing a change in capacitance, thereby achieving proximity or touch detection.

[0031] The induction coil 60 is disposed inside the cavity. In this embodiment, the cover module also includes a circuit board assembly 70, which is disposed on the inner wall of the cavity. The circuit board assembly 70 has a mounting surface, and the induction coil 60 is disposed on the mounting surface of the circuit board assembly 70 and electrically connected to the circuit board assembly 70. The mounting surface of the circuit board assembly 70 is parallel to the plane of motion of the connector during the movement of the cover 10, so that the induction coil 60 and the metal layer 50 can form a stable parallel relative arrangement when the cover 10 is in the closed state.

[0032] Specifically, when the lid 10 is closed, the metal layer 50 and the induction coil 60 are opposite each other with a gap between them. The metal layer 50 and the induction coil 60 do not need to contact each other, forming a non-contact electromagnetic coupling structure. When the lid 10 is subjected to an external force, the connector (cantilever 30) can cause the metal layer 50 to displace relative to the induction coil 60, thereby changing the electromagnetic coupling state between them and causing the induction coil 60 to generate a change in the induced signal. This change in the induced signal is positively correlated with the degree of force on the surface of the lid 10 and the amount of displacement of the metal layer 50, thus enabling the detection of the force state of the lid 10 without contact or electrical connection.

[0033] In this embodiment, the capacitor sensing electrode 40, the induction coil 60, and the circuit board assembly 70 are all located inside the recess of the base shell, i.e., completely within the dry area; while the cover 10, the connector, and the metal layer 50 are located outside the cavity opening, i.e., within the wet area or the dry-wet interface region. Since the metal layer 50 is a passive structure and requires no electrical connection, the cover module achieves a layout where all active electronic components and electrical traces are completely within the dry area, with zero traces on moving parts, maintaining reliable sensing and triggering functions without compromising the dry-wet area separation design.

[0034] This embodiment further illustrates how the cover module effectively distinguishes between valid human touch and unexpected external interference such as hail or rain by fusing the dual-channel signals of the capacitor acquisition electrode 40 and the induction coil 60, thereby avoiding accidental opening.

[0035] Detection characteristics of the capacitor sampling electrode 40: The capacitor sampling electrode 40 operates based on the principle of electric field coupling between a conductor and an electrode. When an external conductor approaches or adheres to the outer surface of the cover 10, a coupling capacitor is formed between the conductor and the capacitor sampling electrode 40 through the dielectric of the cover 10, causing a change in capacitance. As a large-mass conductor, the human body, when touching the outer surface of the cover 10, can form an effective electric field coupling with the capacitor sampling electrode 40 in a localized area, resulting in a significant change in capacitance. However, hailstones are mainly composed of solid ice, which is an insulating medium with extremely low conductivity. Even if hailstones fall and briefly adhere to the outer surface of the cover 10, they cannot form conductor-electrode coupling with the capacitor sampling electrode 40. Furthermore, their limited volume has a negligible effect on the overall electric field distribution of the capacitor sampling electrode 40, therefore, the capacitance value hardly changes significantly. In contrast, rainwater is a conductive liquid containing electrolyte ions. When rainwater hits or adheres to the outer surface of the cover 10, it easily forms a continuous conductive liquid film on the surface of the cover 10. This liquid film, as a large-area conductor, forms a coupling capacitor with the capacitor collection electrode 40 through the cover plate medium of the cover 10. Therefore, even if the rainwater is not touched by a human body, it will still cause a relatively significant change in the capacitance value.

[0036] Detection characteristics of induction coil 60: Induction coil 60 operates based on the principle of electromagnetic induction. When the cover 10 is closed, the metal layer 50 and induction coil 60 are arranged opposite each other with a gap, forming a non-contact electromagnetic coupling structure. When the cover 10 is subjected to an external force, the connector causes the metal layer 50 to displace relative to the induction coil 60, thereby changing the electromagnetic coupling state between them. This causes the induction coil 60 to generate a change in the induced signal, which is positively correlated with the degree of mechanical deformation of the cover 10. When hail falls on the outer surface of the cover 10, the instantaneous impact force generated by the hail is large enough to cause significant mechanical deformation of the cover 10 and the connector. The relative displacement between the metal layer 50 and the induction coil 60 is significant, thus the induction coil 60 will generate a large change in the induced signal. However, when rainwater hits or flows on the outer surface of the cover 10, the impact force and continuous pressure generated by the rainwater are very small, and hardly any identifiable mechanical deformation is caused to the cover 10 and the connector. The relative displacement between the metal layer 50 and the induction coil 60 is negligible, so the change in the induction signal of the induction coil 60 is very small.

[0037] Dual threshold intersection judgment logic: Based on the physical characteristics differences of the two detection channels mentioned above, the circuit board assembly 70 in this embodiment achieves accurate trigger recognition through dual threshold intersection judgment.

[0038] When hail falls, although the induction coil 60 channel produces a significant signal change due to large mechanical deformation, the capacitance acquisition electrode 40 channel has almost no capacitance change due to the insulating properties of hail, and does not reach the first preset threshold. Therefore, the system determines that it is not an effective trigger and does not open the cover 10.

[0039] When rainwater hits the capacitor, although the capacitance of the 40 channel of the capacitor acquisition electrode changes significantly due to the formation of a conductive liquid film in the rainwater and reaches the first preset threshold, the signal of the 60 channel of the induction coil changes very little due to the minimal impact of the rainwater and almost no mechanical deformation. It does not reach the second preset threshold. Therefore, the system also determines that it is not an effective trigger and does not open the cover 10.

[0040] Only when a human touches the cover 10, the human body, as a large-mass conductor, causes the capacitance value to change to the first preset threshold. At the same time, the continuous directional force generated by the human hand pressing causes the connector to drive the metal layer 50 to produce a identifiable relative displacement, causing the signal change of the induction coil 60 to reach the second preset threshold. Only when both channels simultaneously meet the threshold conditions can the system determine that it is a valid trigger and execute the opening action of the cover 10.

[0041] Therefore, by identifying conductor properties through the capacitor channel to exclude non-conductor impacts (such as hail), and by identifying the degree of mechanical deformation through the 60-channel induction coil to exclude liquid adhesion without significant pressure (such as rainwater), the intersection judgment of the two channels effectively solves the problem of easy false triggering of a single sensor under complex working conditions, and significantly improves the environmental immunity and triggering reliability of the cap module.

[0042] This embodiment further illustrates the signal acquisition and processing logic of the circuit board assembly 70 for the capacitor acquisition electrode 40 and the induction coil 60.

[0043] In this embodiment, the circuit board assembly 70 includes a data acquisition module and a control module. The data acquisition module is electrically connected to the capacitor acquisition electrode 40 and the induction coil 60, respectively, and is used to acquire the capacitance change signal value of the capacitor acquisition electrode 40 and the induction signal change value of the induction coil 60. The control module is electrically connected to the data acquisition module and is used to determine whether the cover 10 has been effectively triggered based on the capacitance change signal value and the induction signal change value, so as to output a corresponding control signal.

[0044] To reduce system power consumption and simplify the hardware architecture, the acquisition module is configured to collect the capacitance change signal value and the induction signal change value in a time-division multiplexing manner. Specifically, the control module controls the acquisition module to sample the capacitance acquisition electrode 40 in the first time period and sample the induction coil 60 in the second time period. The two time periods are executed alternately to realize the multiplexing acquisition of dual-channel signals by a single acquisition circuit.

[0045] In terms of signal processing, the control module performs difference calculations on the acquired raw signal data within a preset time window. Specifically, the control module calculates the difference between the signal value at the current sampling moment and the historical reference value, and determines whether the difference reaches the corresponding preset threshold. This difference calculation method can effectively eliminate interference caused by factors such as ambient temperature drift and slow changes in the sensor baseline, improving the stability and dynamic response capability of the detection.

[0046] The control module executes the following judgment logic: Acquire the capacitance change signal value of the capacitor acquisition electrode 40 and the induction signal change value of the induction coil 60; Determine whether the capacitance change signal value reaches the first preset threshold; When the capacitance change signal value reaches the first preset threshold, the sensor collects and determines whether the change value of the sensed signal reaches the second preset threshold. When the change value of the sensing signal reaches the second preset threshold, it is determined that the cover 10 has been effectively triggered, and the cover 10 is controlled to open. Conversely, if the capacitance change signal value does not reach the first preset threshold, or the sensing signal change value does not reach the second preset threshold, it is determined that the cover 10 has an invalid trigger, and the cover 10 is not opened.

[0047] In this embodiment, the cover module can be installed on the vehicle body.

[0048] The vehicle includes a vehicle body and a cover module as described in the previous embodiment. The cover module is installed on the vehicle body, and the energy supply port is used to connect the interior of the vehicle body with an external energy supply device. The vehicle can use the cover module opening control method as described in the previous embodiment to realize the sensor-interactive automatic opening of the cover 10.
