[0042] The locking part is used to lock the filler cap 2. The external pressurized gas entering through the gas channel can push the locking part away from the filler cap 2 to unlock the filler cap 2 and store energy in the first elastic part.

[0043] The energy filler cap locking structure of the present embodiment is provided with a locking portion and a first elastic portion, and a gas channel connected to an external gas source is provided on the filler port seat 1, thereby, the locking portion can be pushed by external pressurized gas entering through the gas channel to unlock the filler cap 2. Compared with the existing structure, the arrangement of other driving devices such as motors can be omitted, which is not only convenient for setting, but also can effectively reduce costs.

[0044] Based on the above design concept, an exemplary structure of the energy filling port cover locking structure of this embodiment is referred to as follows: Figures 1 to 3 The structure of the filler cap 2 can refer to the prior art, and the structure of the filler seat 1 can refer to Figure 1 and Figure 2 As shown in , its overall structure is roughly the same as the prior art. Specifically, the filler seat 1 of this embodiment is provided with a housing cavity 1021, and an air inlet pipe 103 and an air outlet pipe 104 connected to the housing cavity 1021. The above-mentioned gas channel includes the housing cavity 1021, an air inlet channel provided in the air inlet pipe 103, and an air outlet channel provided in the air outlet pipe 104, and the locking portion is slidably provided in the housing cavity 1021.

[0045] In this embodiment, the accommodating cavity 1021, the air inlet pipe 103 and the air outlet pipe 104 are provided on the filling port seat 1, so as to facilitate the arrangement of the locking part and the gas passage. Figure 1 and Figure 2 In the embodiment, the filler seat 1 includes a seat body 101, and a locking seat 102 disposed outside the seat body 101, and the above-mentioned accommodating cavity 1021 is specifically disposed on the locking seat 102. In addition, the structure of the seat body 101 of the embodiment is the same as the existing technology, and there is a passage for the fuel gun or charging gun to pass through. Furthermore, a protective cover is provided at the end of the seat body 101 facing away from the filler cap 2, and in the specific implementation, the specific structure of the filler seat 1 can refer to the existing technology, and will not be described in detail here.

[0046] As a preferred embodiment, Figure 3 As shown in the figure, the locking part of this embodiment includes a locking rod 3 and an abutting plate 4 connected to each other, and the locking rod 3 is used to lock the filler cap 2. The abutting plate 4 abuts against the inner wall of the accommodating cavity 1021 and guides the locking part to slide relative to the filler seat 1. In this embodiment, by providing the abutting plate 4, the locking part can be guided to slide, so as to facilitate accurate reset under the driving of the first elastic part.

[0047] As a specific embodiment, one end of the accommodating cavity 1021 is open, and a cover plate for blocking the open end is provided on the locking seat 102, and the locking rod 3 passes through the cover plate. At the same time, the locking rod 3 abuts against the cover plate, which can not only improve the sealing performance of the communicating part between the accommodating cavity 1021 and the air inlet pipe 103, but also guide the sliding of the locking rod 3. The first elastic member is specifically a spring provided in the accommodating cavity 1021.

[0048] In addition, as a further embodiment, Figure 3 As shown in , a through pressure relief hole 401 is provided on the abutment plate 4. In this embodiment, by providing the pressure relief hole 401 on the abutment plate 4, it is convenient for the pressurized gas to be discharged after the filler cap 2 is unlocked. In this embodiment, in order to realize the locking of the filler cap 2 by the locking part, as a preferred embodiment, an adsorption part is provided between the locking part and the filler cap 2, and the locking part locks the filler cap 2 through the adsorption part. The locking part of this embodiment locks the filler cap 2 through the adsorption part, which has a simple structure and is also convenient for unlocking the filler cap 2.

[0049] Moreover, as a specific embodiment, Figure 3 As shown in , the adsorption part includes a first magnetic part 5 provided on the locking part, and a second magnetic part 6 provided on the filler cap 2. Moreover, when the filler cap 2 covers the filler seat 1, the second magnetic part 6 and the first magnetic part 5 can be adsorbed together. Among them, the first magnetic part 5 is specifically provided at one end of the lock rod 3 close to the filler cap 2, and the first magnetic part 5 and the second magnetic part 6 can specifically adopt conventional magnetic structures such as magnets or magnetic strips in the prior art, and the technology is mature and easy to design and implement.

[0050] It should be noted that, since the filler cap 2 is generally made of metal, the adsorption portion may include only the first magnetic member 5 in addition to the first magnetic member 5 and the second magnetic member 6. That is, in this case, the second magnetic member 6 is not provided on the filler cap 2, and the filler cap 2 can also be adsorbed by the first magnetic member 5. In addition, in addition to locking the filler cap 2 by the adsorption portion, the locking portion may also cover the outer side of the locking rod 3 with an elastic pad. In this case, it is also feasible to utilize the elastic properties of the elastic pad to insert the locking rod 3 into the slot to achieve the locking of the filler cap 2 by the locking portion.

[0051] In addition, to further improve the use effect, as a preferred embodiment, the filler cap 2 is hinged on the filler seat 1. At the same time, a second elastic part is provided between the filler cap 2 and the filler seat 1, and the second elastic part is used to drive the unlocked filler cap 2 to flip open. The second elastic part is specifically a torsion spring provided on the rotating shaft of the filler cap 2. In this embodiment, by providing the second elastic part, the unlocked filler cap 2 is facilitated to open automatically, which can improve the convenience of use.

[0052] The energy filling port cover locking structure of this embodiment adopts the above structure, and the filling port cover 2 can be opened without using a driving device such as a motor, so the setting of the driving device can be omitted, which is beneficial to reducing the processing cost and facilitating the layout. In addition, the mechanical structure is more reliable than the traditional electric method to realize the opening and closing of the filling port.

[0053] Embodiment 2

[0054] This embodiment relates to a vehicle, which is provided with the energy filling port cover locking structure as in the first embodiment. And, as a further embodiment, Figure 4 As shown in , the vehicle of this embodiment is provided with a fuel filler cap assembly M and a charging port cap assembly N, and both the fuel filler cap assembly M and the charging port cap assembly N are provided with an energy filler cap locking structure as in the first embodiment.

[0055] In addition, similar to the prior art, the vehicle of this embodiment also uses a fuel leakage diagnosis module when performing fuel evaporation emission diagnosis, and the fuel leakage diagnosis module is specifically composed of an air pump 8, a solenoid valve 7 and a heating circuit. The air pump 8 can actively pump air into the fuel tank system to pressurize it, and by feeding back its own pump current, it is used for corresponding leakage diagnosis.

[0056] Based on this, as a further implementation, the vehicle of this embodiment is provided with a solenoid valve 7 connected to the body control module, and the solenoid valve 7 has a first communication port 701, a second communication port 702 selectively connected to the first communication port 701, and a third communication port 703 arranged in a one-to-one correspondence with the gas channel. Among them, the first communication port 701 is connected to the air pump 8 of the fuel tank leakage diagnosis module of the vehicle, the second communication port 702 is connected to the carbon canister 9 on the vehicle, and the third communication port 703 is connected to the gas channel.

[0057] As a specific embodiment, Figure 3 As shown in , the structures of the fuel filler cap assembly M and the charging port cap assembly N of this embodiment are roughly the same, and there are two third connecting ports 703 arranged in a one-to-one correspondence with the two. Moreover, one of the third connecting ports 703 is connected to the gas channel of the fuel filler cap assembly M, and the other third connecting port 703 is connected to the gas channel of the charging port cap assembly N. It should be mentioned here that in addition to providing the above-mentioned energy filler cap locking structure on both the fuel filler cap assembly M and the charging port cap assembly N, the above-mentioned energy filler cap locking structure can also be provided on only one of the two. Moreover, it can be understood that the energy filler cap locking structure can be used not only for the hybrid vehicle model of this embodiment, but also for traditional fuel vehicles or new energy electric vehicles.

[0058] Combination Figure 3 and Figure 4As shown in the figure, the opening and closing process of the filler cap 2 is described by taking the fuel filler cap assembly M as an example, and the opening and closing process of the charging port cap can be referred to below and will not be repeated here. Specifically, when the vehicle of this embodiment performs fuel leakage diagnosis, the first connecting port 701 and the second connecting port 702 of the solenoid valve 7 are connected, and then the air pump 8 of the fuel leakage diagnosis module is started. For a closed fuel tank system, its pressure will gradually increase, and the corresponding pump current will also gradually increase, so as to determine whether there is a leak in the system.

[0059] When controlling the opening and closing of the fuel filler cap, first press the opening switch (usually located on the dashboard, refer to the prior art) to transmit the refueling signal demand to the body control module and the engine control unit. Then, the engine control unit sends a fuel tank pressure relief command to the fuel tank cut-off valve to release the internal pressure of the fuel tank. When the internal pressure of the fuel tank reaches equilibrium, the body control module controls the solenoid valve 7 to connect the first connecting port 701 and the third connecting port 703 connected to the gas channel of the fuel filler cap assembly M. Subsequently, the body control module controls the air pump 8 to start, pumping air into the gas channel of the fuel filler cap assembly M to increase the internal air pressure.

[0060] At this time, the locking part compresses the spring and moves downward with the help of the gas pressure in the gas channel, so that the first magnetic part 5 on the locking rod 3 is separated from the second magnetic part 6 on the filler cap 2. The filler cap 2 automatically opens under the action of the torsion spring. When the locking rod 3 moves downward, the air pump 8 is controlled to stop working, and the pressurized gas in the gas channel passes through the pressure relief hole 401 and the air outlet and enters the carbon canister 9 for storage. At the same time, the locking part is reset to the initial position under the pushing action of the spring. After refueling is completed, press the filler cap 2 to make the second magnetic part 6 and the first magnetic part 5 attract each other, and the locking part locks the filler cap 2.

[0061] The vehicle of this embodiment adopts the above structure, so that it is not necessary to set a driving device such as a motor on the fuel filler cap assembly M and the charging port cap assembly N, which can reduce the number of driving devices and reduce costs. In addition, the mechanical structure is more advantageous than the traditional electric method to realize the opening and closing of the fuel filler cap 2, which can improve the reliability of the vehicle.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
