[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] The following will refer to Figure 1 and Figure 2 The utility model is described in detail in conjunction with the embodiments.

[0041] like Figure 1 and Figure 2 As shown, the fuel filler cap assembly 100 according to the embodiment of the utility model includes a fuel filler cap 10, a moving part 20, a prompting part 30 and a switch part 40. The fuel filler cap 10 is used to cover the fuel filler port of the fuel tank; the moving part 20 is arranged on the fuel filler cap 10, and the moving part 20 is configured to be able to move along a set direction when the internal pressure of the fuel tank changes; the prompting part 30 and the switch part 40 are electrically connected, and the prompting part 30 and the switch part 40 are arranged on the fuel filler cap 10. When the internal pressure of the fuel tank is greater than a preset value, the moving part 20 triggers the switch part 40 so that the prompting part 30 sends a prompt message; when the internal pressure of the fuel tank is less than a preset value, the moving part 20 is separated from the switch part 40 so that the prompting part 30 stops sending the prompt message.

[0042] Specifically, the fuel filler cap 10 is used to cover the fuel filler opening of the fuel tank; for example, the fuel filler cap 10 can be threadedly connected to the fuel filler opening of the fuel tank and a sealing ring is provided to seal the gap between the fuel filler cap 10 and the fuel filler opening.

[0043] The moving member 20 is provided on the fuel filler cap 10, and the moving member 20 is configured to move in a set direction when the internal pressure of the fuel tank changes; for example, when the internal pressure of the fuel tank increases, the moving member 20 moves in a direction away from the fuel filler cap, and when the internal pressure of the fuel tank decreases, the moving member 20 moves in a direction close to the fuel filler cap. The fuel filler cap 10 may be provided with a guide portion 1010 so that the moving member 20 is not easy to deviate from the set direction during the movement, and the set direction may be the axial direction of the fuel filler cap.

[0044] The prompting member 30 is electrically connected to the switch member 40. When the switch member 40 is in a disconnected state, the power source 50 cannot supply power to the prompting member 30, and the prompting member 30 cannot send out a prompt message. When the switch member 40 is in a connected state, the power source 50 can supply power to the prompting member 30, so that the prompting member 30 can send out a prompt message. The switch member 40 can be a micro switch, etc., so that the switch member 40 can be triggered after the moving member 20 moves to a certain position. After the moving member 20 leaves a certain position, the moving member 20 separates from the switch member 40, and the switch member 40 switches to a disconnected state.

[0045] The prompting member 30 and the switch member 40 are provided on the fuel filler cap 10. For example, the prompting member 30 can be provided on the side of the fuel filler cap 10 directly facing the user, for example, on the end surface of the fuel filler cap 10 facing away from the fuel filler port, so that the user can directly observe the prompting member 30. The fuel filler cap 10 can be provided with a mounting hole for facilitating the installation of the prompting member 30, or the position where the prompting member 30 is provided on the fuel filler cap 10 is a light-transmitting portion, so that the user can observe the prompting member 30 provided inside the fuel filler cap 10.

[0046] The switch component 40 is arranged on the fuel filler cap 10 instead of the moving component 20, that is, the switch component 40 does not move with the movement of the moving component 20, and the position of the switch component 40 is fixed, so that the switch component 40 has good working stability and low failure rate, thereby making the prompt component 30 of the present application have better working stability, lower failure rate and longer service life. At the same time, compared with setting two parts respectively fixed on the moving component 20 and the fuel filler cap 10, the switch component 40 of the present application is a component, which can be directly fixed on the fuel filler cap 10, which is less difficult to arrange, has fewer assembly steps, and requires lower arrangement accuracy.

[0047] When the internal pressure of the fuel tank is greater than the preset value, the moving part 20 triggers the switch part 40 so that the switch part 40 can conduct the power supply 50 and the prompt part 30, so that the prompt part 30 sends a prompt message, so that the user can directly know from the prompt message sent by the prompt part 30 that the internal pressure of the fuel tank is still relatively large, and the fuel filler cap 10 and the fuel filler port cannot be separated, and the pressure relief needs to be continued; when the internal pressure of the fuel tank is less than the preset value, the moving part 20 is separated from the switch part 40, so that the moving part 20 cannot continue to trigger the switch part 40, the power supply 50 and the prompt part 30 are no longer conducted, and the prompt part 30 stops sending prompt messages, so that the user can directly know that the pressure relief has been completed and can directly separate the fuel filler cap 10 and the fuel filler port. Therefore, the user does not need to repeatedly rotate the fuel filler cap 10 to confirm whether the pressure relief is completed and whether the fuel filler cap 10 and the fuel filler port can be separated. Therefore, the fuel filler cap 10 of the present application is more convenient to use.

[0048] The prompt member 30 can send out a prompt message, and the prompt message sent out by the prompt member 30 may be a light signal, a sound signal, a vibration signal, or after the prompt member 30 is triggered, the size of the prompt member 30 may change (for example, the prompt member 30 may be a small telescopic rod, which extends when powered on and shortens when powered off), so that the user can judge the relationship between the internal pressure of the fuel tank and the preset value based on the size change of the prompt member 30.

[0049] According to the fuel filler cap assembly 100 of the embodiment of the utility model, by setting a prompt member 30, the prompt member 30 will send a prompt message when the internal pressure of the fuel tank is greater than a preset value, and will stop sending the prompt message when the internal pressure of the fuel tank is less than the preset value, so that the user can judge whether the fuel tank pressure relief is completed by observing whether the prompt member 30 sends a prompt message, without repeatedly rotating the fuel filler cap 10 to confirm whether the pressure relief is completed, which is more convenient to use; at the same time, the present application sets a moving member 20 and a switch member 40, and the moving member 20 can trigger the switch member 40 or separate from the switch member 40 by moving along the set direction. The switch member 40 is directly arranged on the fuel filler cap 10 instead of on the moving member 20. The position of the switch member 40 is fixed and arranged on the fuel filler cap 10. Therefore, the prompt member 30 of the present application has better working stability, lower failure rate, longer service life, lower layout difficulty, fewer assembly steps, and lower layout accuracy requirements.

[0050] According to some embodiments of the present invention, the fuel filler cap assembly 100 further includes a power source 50 . The power source 50 is disposed on the fuel filler cap 10 . The power source 50 is electrically connected to the prompting member 30 to supply power to the prompting member 30 .

[0051] For example, the power source 50 is a mobile power source provided on the fuel filler cap 10, and the mobile power source is directly used to power the prompting member 30, and the mobile power source can be replaced. Figure 1 and Figure 2As shown, the power supply 50 includes a first wireless power supply coil 501 and a second wireless power supply coil 502. The first wireless power supply coil 501 is provided on the fuel filler cap 10 and is electrically connected to the prompting member 30 for supplying power to the prompting member 30. The second wireless power supply coil 502 is used for wireless induction power supply to the first wireless power supply coil 501. The second wireless power supply coil 502 is connected to an external power supply, and the external power supply supplies power to the second wireless power supply coil 502. For example, the external power supply can be a vehicle-mounted power supply. The external power supply supplies power to the second wireless power supply coil 502. The changing current in the second wireless power supply coil 502 will generate a changing magnetic field. The changing magnetic field reaches the first wireless power supply coil 501. The first wireless power supply coil 501 will induce an electromotive force in the changing magnetic field according to Faraday's law of electromagnetic induction, thereby generating a current to supply power to the prompting member 30.

[0052] In other embodiments, the power source 50 may not be disposed on the fuel filler cap 10. For example, the power source 50 is the original power source of the vehicle, and the prompt element 30 and the switch element 40 are electrically connected to an external power source via wires.

[0053] In the embodiment where the power supply 50 includes a first wireless power supply coil 501 and a second wireless power supply coil 502, the first wireless power supply coil 501 is arranged on the fuel filler cap 10 and is electrically connected to the prompt member 30 for supplying power to the prompt member 30, and the second wireless power supply coil 502 is used to wirelessly inductively supply power to the first wireless power supply coil 501, the second wireless power supply coil 502 is not arranged on the fuel filler cap 10, the second wireless power supply coil 502 is connected to an external power supply, and the external power supply supplies power to the second wireless power supply coil 502, so that the second wireless power supply coil 502 can supply power to the first wireless power supply coil 501, so that the first wireless power supply coil 501 supplies power to the prompt member 30.

[0054] By providing the first wireless power supply coil 501 and the second wireless power supply coil 502, on the one hand, the reminder member 30 provided on the fuel filler cap 10 does not need to be connected to the external power supply through a wire, and the fuel filler cap 10 can be replaced as a separate component, which is conducive to reducing the difficulty of replacement and maintenance of the fuel filler cap 10, and is not prone to the problem of wire aging and damage; on the other hand, there is no need to consider the problem of regular replacement when the power source 50 is a battery. The second wireless power supply coil 502 can supply power to the first wireless power supply coil 501 for a long time, which is more convenient to use and the probability of the reminder member 30 being unable to be used due to lack of power supply is reduced.

[0055] According to some embodiments of the present invention, reference can be made to Figure 1 and Figure 2As shown, the power supply 50 includes a first wireless power supply coil 501, a second wireless power supply coil 502 and a battery 503. The battery 503 is connected to the prompt member 30 to supply power to the prompt member 30. The battery 503 is also used to be connected to the first wireless power supply coil 501 to store the electric energy provided by the second wireless power supply coil 502 to the first wireless power supply coil 501.

[0056] After the second wireless power supply coil 502 supplies power to the first wireless power supply coil 501, the first wireless power supply coil 501 will supply power to the battery 503, so that the battery 503 stores part of the electrical energy. When the second wireless power supply coil 502 does not stably supply power to the first wireless power supply coil 501, at this time, the battery 503 can supply power to the prompt member 30 for a short time, so that the prompt member 30 can stably send out prompt information. The setting of the battery 503 can increase the voltage stability of the prompt member 30, that is, the voltage applied to the two ends of the prompt member 30 is maintained at a relatively stable voltage level, so that the prompt member 30 can send out prompt information more continuously and stably.

[0057] According to some embodiments of the present invention, reference can be made to Figure 1 and Figure 2 As shown, the power supply 50 further includes a capacitor 504 , which is connected in parallel with the prompting member 30 and in series with the first wireless power supply coil 501 .

[0058] A capacitor 504 is set. After the second wireless power supply coil 502 supplies power to the first wireless power supply coil 501, the first wireless power supply coil 501 will supply power to the capacitor 504, so that the capacitor 504 stores part of the electrical energy. When the second wireless power supply coil 502 fails to stably supply power to the first wireless power supply coil 501, at this time, the capacitor 504 can supply power to the prompt member 30 for a short time, so that the prompt member 30 can stably send out prompt information, thereby improving the working stability of the prompt member 30.

[0059] According to some embodiments of the utility model, the power supply 50 also includes a battery 503 and a capacitor 504. The battery 503 is connected to the prompt member 30 for supplying power to the prompt member 30. The battery 503 is also used to be connected to the first wireless power supply coil 501 to store the electrical energy provided by the first wireless power supply coil 501; the capacitor 504 is connected in parallel with the prompt member 30 and in series with the first wireless power supply coil 501.

[0060] After the second wireless power supply coil 502 supplies power to the first wireless power supply coil 501, the first wireless power supply coil 501 supplies power to the capacitor 504 and the battery 503, so that the capacitor 504 and the battery 503 store some electric energy. When the second wireless power supply coil 502 does not stably supply power to the first wireless power supply coil 501, at this time, the capacitor 504 and the battery 503 can supply power to the prompt member 30, so that the prompt member 30 can stably send out prompt information, thereby improving the working stability of the prompt member 30. The simultaneous provision of the capacitor 504 and the battery 503 can further improve the working stability of the prompt member 30.

[0061] According to some embodiments of the present invention, reference can be made to Figure 1 and Figure 2 As shown, the fuel filler cap 10 includes a first accommodation space 101 and a second accommodation space 102 arranged axially and a through hole 103 connecting the first accommodation space 101 and the second accommodation space 102; for example, the inner space of the end of the fuel filler cap 10 away from the fuel filler port is formed as the second accommodation space 102, and the second accommodation space 102 is usually arranged with fewer parts, so it is easy to arrange the switch member 40 and the prompt member 30 in the second accommodation space 102. The through hole 103 can be gap-matched with the trigger part 202, or the size of the through hole 103 is much larger than the size of the trigger part 202 perpendicular to the set direction, all of which should be within the protection scope of this application.

[0062] The movable member 20 includes a movable body 201 and a trigger part 202. The movable body 201 is arranged in the first accommodating space 101, the switch member 40 and the prompt member 30 are arranged in the second accommodating space 102, and the trigger part 202 is penetrated through the through hole 103. The movable body 201 is configured to be movable along a set direction when the internal pressure of the oil tank changes to drive the trigger part 202 to move between a first position range and a second position range. In the first position range, the trigger part 202 triggers the switch member 40 to make the prompt member 30 send out a prompt message; in the second position range, the trigger part 202 is separated from the switch member 40 to make the prompt member 30 stop sending out the prompt message.

[0063] By providing a trigger portion 202 on the movable member 20, the trigger portion 202 follows the movement of the movable member 20 to trigger the switch member 40 located in the second accommodating space 102 or is separated from the switch member 40. In this way, the structure of the entire fuel filler cap 10 is simpler and the arrangement difficulty of the switch member 40 and the trigger portion 202 is lower.

[0064] According to some embodiments of the present invention, reference can be made to Figure 1 and Figure 2As shown, the fuel filler cap 10 includes a first shell 104 and a second shell 105. The first shell 104 is used to connect with the fuel filler port of the fuel tank. The first shell 104 is provided with a fixed ratchet 106. The fixed ratchet 106 can rotate synchronously with the first shell 104. The first shell 104 is provided with a connecting channel 1041. The connecting channel 1041 is connected to the oil storage chamber of the fuel tank and an elastic membrane layer 1042 is provided in the connecting channel 1041.

[0065] The second shell 105 is connected to the first shell 104, and the second shell 105 includes a handle portion 107. The second shell 105 is provided with a floating ratchet 108 and a floating member 109. The floating ratchet 108 can rotate synchronously with the second shell 105. One end of the floating member 109 is in contact with the elastic membrane layer 1042. The elastic membrane layer 1042 can be deformed under the action of the pressure in the oil storage chamber to drive the floating member 109 to move along a set direction. The floating member 109 is penetrated by the fixed ratchet 106 and the other end is connected to the floating ratchet 108. The floating ratchet 108 is a movable body 201; in the first position range, the floating ratchet 108 and the fixed ratchet 106 are separated from each other; in the second position range, the floating ratchet 108 and the fixed ratchet 106 are plug-fitted.

[0066] Specifically, a stopper is provided between the second housing 105 and the first housing 104 to limit the relative position of the first housing 104 and the second housing 105 in the axial direction, so that the first housing 104 will not be axially disengaged from the second housing 105. The second housing 105 has a guide portion 1010, which is used to guide the movement of the floating ratchet 108.

[0067] You can refer to Figure 1 As shown, during normal use of the fuel tank or before the fuel tank is depressurized, the elastic membrane layer 1042 bulges outward and abuts against the floating member 109, so that the floating member 109 abuts against the floating ratchet 108, the floating ratchet 108 and the fixed ratchet 106 are separated from each other, and the trigger part 202 is in the first position range. The trigger part 202 can trigger the switch part 40 to turn on the power supply 50 and the prompt part 30, and the prompt part 30 can send a prompt message. At this time, when the second shell 105 is rotated, the second shell 105 will idle relative to the first shell 104, and the fuel port cannot be separated from the fuel cap 10.

[0068] As the pressure relief process proceeds, the expansion degree of the elastic membrane layer 1042 gradually decreases, and the floating member 109 gradually moves in a set direction and close to the first shell 104 under the action of gravity or the elastic force of the elastic member; when the elastic membrane layer 1042 returns to a certain state (see Figure 2As shown in the figure, the floating ratchet 108 and the fixed ratchet 106 are plugged together. At this time, the trigger part 202 moves to the second position range and separates from the switch part 40, the prompt part 30 and the power supply 50 are no longer connected, and the prompt part 30 no longer sends out prompt information. Since the floating ratchet 108 and the fixed ratchet 106 are plugged together, the user can rotate the second shell 105 through the handle 107, thereby driving the first shell 104 to rotate, so that the fuel filler cap 10 and the fuel filler port are separated. When the pressure relief is not completed, the second shell 105 in the present application will idle relative to the first shell 104, and the fuel filler cap 10 cannot be separated from the fuel filler port, which is safer to use.

[0069] According to some embodiments of the present invention, the first wireless power supply coil 501 is disposed on the second housing 105. Since the first housing 104 needs to rotate relative to the second housing 105, and the prompting member 30 is disposed on the second housing 105, the first wireless power supply coil 501 is disposed on the second housing 105, and the first wireless power supply coil 501 can rotate synchronously with the prompting member 30, and the first wireless power supply coil 501 and the prompting member 30 can be directly connected by a wire, which is conducive to simplifying the structure.

[0070] In some embodiments, the first wireless power supply coil 501 is arranged at the part of the second shell 105 close to the first shell 104, and the second wireless power supply coil 502 is arranged radially outside the first shell 104. In this way, the distance between the first wireless power supply coil 501 and the second wireless power supply coil 502 is shorter, which is conducive to achieving more efficient energy transfer.

[0071] In some embodiments, the first wireless power supply coil 501 and the second wireless power supply coil 502 are coaxially arranged, so that the energy transfer efficiency between the first wireless power supply coil 501 and the second wireless power supply coil 502 is higher.

[0072] According to some embodiments of the present invention, the reminder member 30 includes one or more of an acoustic reminder device, an optical reminder device, a tactile reminder device, and a mechanical moving component.

[0073] The acoustic reminder device can emit a reminder sound, which can be a language reminder sound, for example, "pressure relief is complete", or a "beep" sound can be emitted to achieve the purpose of reminder. The optical reminder device can emit light or present a certain pattern to indicate that the pressure relief is complete.

The mechanical moving component can change position under electric drive to remind the user. The reminder member 30 in the present application can be a combination of one or more of the above-mentioned devices, and is not specifically limited here.

[0074] A second aspect of the utility model is to provide a fuel system.

[0075] The fuel system according to the embodiment of the utility model includes a fuel tank and a fuel filler cap assembly 100 according to the embodiment of the utility model.

[0076] The fuel system according to the embodiment of the second aspect of the utility model comprises a fuel tank and a fuel filler cap assembly 100 according to the embodiment of the first aspect of the utility model. Since the fuel tank of the second embodiment of the utility model includes the fuel filler cap assembly 100 of the first embodiment of the utility model, the fuel system of the second embodiment of the utility model includes at least the following advantages: by setting the prompt member 30, the prompt member 30 will issue a prompt message when the internal pressure of the fuel tank is greater than a preset value, and will stop issuing the prompt message when the internal pressure of the fuel tank is less than the preset value, so that the user can judge whether the fuel tank pressure relief is completed by observing whether the prompt member 30 issues a prompt message, without repeatedly rotating the fuel filler cap 10 to confirm whether the pressure relief is completed, which is more convenient to use; at the same time, the present application sets a moving member 20 and a switch member 40, and the moving member 20 can trigger the switch member 40 or separate from the switch member 40 by moving along the set direction. The switch member 40 is directly arranged on the fuel filler cap 10 instead of on the moving member 20. The position of the switch member 40 is fixed and arranged on the fuel filler cap 10. Therefore, the prompt member 30 of the present application has better working stability, lower failure rate, longer service life, lower layout difficulty, fewer assembly steps, and lower layout accuracy requirements.

[0077] According to some embodiments of the utility model, the fuel filler cap assembly 100 includes a power supply 50 for supplying power to the prompt member 30, the power supply 50 includes a first wireless power supply coil 501 and a second wireless power supply coil 502, the first wireless power supply coil 501 is arranged on the fuel filler cap 10; the fuel tank includes a fuel filler pipe, the second wireless power supply coil 502 is arranged at the end of the fuel filler pipe for connecting to the fuel filler cap 10, and the second wireless power supply coil 502 is used to wirelessly inductively power the first wireless power supply coil 501 when the fuel system's fueling switch is turned on.

[0078] Among them, the second wireless power supply coil 502 is arranged at the end of the fuel pipe for connecting to the fuel filler cap 10, so that the distance between the second wireless power supply coil 502 and the first wireless power supply coil 501 is short, which is conducive to efficient energy transfer between the second wireless power supply coil 502 and the first wireless power supply coil 501.

[0079] The second wireless power supply coil 502 is used to wirelessly inductively power the first wireless power supply coil 501 when the refueling switch of the fuel system is turned on. It should be noted that when the refueling switch of the fuel system is turned on, the fuel tank FTIV (fuel tank isolation valve) in the fuel system will begin to depressurize the oil storage chamber of the fuel tank. At the same time, the vehicle begins to power the second wireless power supply coil 502 so that the second wireless power supply coil 502 can wirelessly power the first wireless power supply coil 501, that is, the second wireless power supply coil 502 is only powered when the refueling switch is turned on and the pressure relief begins to refuel the fuel tank after the pressure relief is completed. In this way, the consumption of electric energy can be reduced.

[0080] In some optional embodiments, the fuel tank may be a high-pressure fuel tank used in a plug-in hybrid electric vehicle (PHEV).
