Example one

The embodiment relates to a vehicle oil supply structure, which comprises at least two oil tanks 1 in the whole structure, wherein each oil tank 1 is arranged in a vehicle, each oil tank 1 is respectively provided with a corresponding fuel pump 4, and simultaneously, each oil tank 1 is also respectively provided with an oil supply pipeline. In addition, the vehicle fuel supply structure of the present embodiment further includes a switching valve 3, the switching valve 3 is connected to the fuel supply lines of the fuel tanks 1, and is connected to the fuel inlet line of the engine 2, and the fuel inlet line is selectively communicated with the fuel supply line of one of the fuel tanks 1 through the switching valve 3.

With the above structure, in the vehicle fuel supply structure of the present embodiment, the fuel pumps 4 are respectively disposed at the fuel tanks 1, and the fuel supply pipelines are switched by the switching valve 3, so that the fuel inlet pipeline of the engine 2 can be communicated with the fuel supply pipeline of one of the fuel tanks 1, thereby achieving the purpose of independently supplying fuel by using different fuel tanks 1, and improving the reliability of the vehicle.

Based on the overall design as described above, as a preferred exemplary structure, as shown in fig. 1, in the present embodiment, the number of the tanks 1 is set to two, and one of them is exemplified as the main tank 101 and the other is exemplified as the sub-tank 102.

Note that, as shown in fig. 1, as one of the embodiments, when an oil supply line is provided only at each oil tank 1 and an oil supply line is provided only at the engine 2. In the preferred embodiment, a check valve, not shown, is also provided in the fuel supply line of each fuel tank 1 to prevent the occurrence of mixed flow between the main and sub-tanks. In addition to the check valve disposed on the oil supply line, the present embodiment may further include a check valve disposed on the oil inlet line of the engine to ensure the stability of the oil supply to the engine 2.

In specific implementation, the check valve described above can be implemented by adopting a valve structure with one-way flow characteristics, which is conventional in the art. In addition, it should be noted that, for the situation that only oil supply pipelines are arranged at the oil tanks 1 and only oil inlet pipelines are arranged at the engine 2, when in specific use, the vehicle oil supply system generally works in the existing oil supply on demand mode, that is, the engine ECU obtains the oil inlet amount required by the engine 2 according to the load of the whole vehicle, and then controls the fuel pump 4 in the working state to supply oil according to the corresponding flow.

In this embodiment, in addition to the above-mentioned case that only the oil supply line is provided at each oil tank 1 and only the oil inlet line is provided for the engine 2, as another embodiment, as shown in fig. 2, further, each oil tank 1 is provided with an oil return line, the engine 2 is also provided with an oil outlet line, and the switching valve 3 is also connected to the oil outlet line and each oil return line, and the oil outlet line can be selectively connected to one of the oil return lines through the switching valve 3.

At this time, it should be noted that, at the same time, the oil return line connected to the oil outlet line of the engine 2 and the oil supply line connected to the oil inlet line of the engine 2 belong to the same oil tank 1. In addition, in the specific implementation, referring to fig. 3 to 5, the supply and return lines on the main oil tank 101 are a main oil tank supply pipe 1011 and a main oil tank return pipe 1012, respectively, the supply and return lines on the auxiliary oil tank 102 are an auxiliary oil tank outlet pipe 1021 and an auxiliary oil tank return pipe 1022, respectively, and the supply and return lines of the engine 2 are an engine inlet pipe 201 and an engine outlet pipe 202, respectively.

The main tank 101 is also provided with a main tank vent pipe 1013, a main tank filler pipe 1014, and a main tank filler return pipe 1015, and the sub-tank 102 is also provided with a sub-tank vent pipe 1023, a sub-tank filler pipe 1024, and a sub-tank filler return pipe 1025. In addition, a fuel filter 5 is provided in the oil inlet and outlet lines of the engine 2 to stabilize the operation of the engine 2. In this case, the fuel filter 5 is generally disposed on the engine intake pipe. The fuel filter 5 functions to remove solid impurities such as iron oxide and dust contained in the fuel and prevent the fuel system from being clogged. Mechanical wear is reduced, stable operation of the engine 2 is ensured, and vehicle reliability is improved.

The main tank filler pipe 1014 and the sub tank filler pipe 1024 are connected to the filler opening of the vehicle to be used for filling the two fuel tanks 1, respectively. The main tank vent pipe 1013, the main tank refueling return pipe 1015, the sub tank vent pipe 1023 and the sub tank refueling return pipe 1025 are used to keep the air pressure in each tank 1 in a safe state. The connection mode among the pipelines can refer to the connection mode of the pipelines of the existing vehicle oil supply system, and is not described herein again.

In this embodiment, the main tank oil supply pipe 1011, the main tank oil return pipe 1012, the sub-tank oil outlet pipe 1021, the sub-tank oil return pipe 1022, and the engine oil inlet pipe 201 and the engine oil outlet pipe 202 are all communicated with the switching valve 3. The switching valve 3 is specifically a two-position six-way reversing valve. In addition, as a preferred embodiment, in the above two embodiments, the fuel pump 4 in each fuel tank 1 is also preferably a built-in fuel pump installed in the fuel tank 1.

In addition, it is worth mentioning that the vehicle oil supply structure of the embodiment is particularly suitable for light passenger vehicles, off-road vehicles, pickup trucks and other vehicle types with double oil tanks.

When the vehicle fuel supply structure of the embodiment is used, when the auxiliary fuel tank 102 is needed to supply fuel, the control switch valve 3 is switched to the fuel supply state of the auxiliary fuel tank 102, at this time, the auxiliary fuel tank outlet pipe 1021 can be communicated with the engine inlet pipe 201, the auxiliary fuel tank return pipe 1022 can be communicated with the engine outlet pipe 202, and the fuel pump 4 in the auxiliary fuel tank 102 is correspondingly controlled to be in the working state, so that after the engine 2 is ignited, the fuel pump 4 in the auxiliary fuel tank 102 starts to work, and independent fuel supply can be performed by the auxiliary fuel tank 102.

When the fuel needs to be switched to the main fuel tank 101 for supply, it can be understood that the switching principle is the same as the switching principle to the auxiliary fuel tank 102, and the switching is performed by controlling the switching valve 3 to operate, and the fuel pump 4 in the main fuel tank 101 is controlled to enter the operating state.

Example two

The utility model relates to a vehicle, which is provided with a vehicle oil supply structure in the first embodiment and is also provided with a trigger module 6 and a control module 7.

At this time, as shown in fig. 6, the trigger module 6 of the present embodiment is triggered to output a trigger signal. The control module 7 is connected to the trigger module 6, the switching valve 3, and the fuel pump 4 in each fuel tank 1. And the control module 7 can control the switching valve 3 to execute switching action and select to open the corresponding fuel pump 4 in response to the trigger signal output by the trigger module 6.

In particular, in a full-vehicle arrangement, the triggering module 6 is typically integrated in the host machine of the vehicle and may be generally configured as a physical key, or as a virtual key in the host machine. The physical keys may be arranged on the dashboard and may be implemented using a conventional key structure, and the virtual keys may be virtual keys integrated in a central control display of the vehicle. Thus, by pressing or touching the trigger module 6, which outputs a trigger signal, the trigger module 7 can send a control signal to the switching valve 3 to control the switching valve 3 to perform a switching operation, thereby selecting the main tank 101 or the sub-tank 102 to supply oil.

In the present embodiment, the control module 7 may be, for example, an engine ECU, and may be connected to other components through a vehicle CAN bus. In addition, in use, it is generally possible to set the main engine system of the vehicle to supply fuel from the main fuel tank 101 by default, and it is also possible to set the main engine system of the vehicle to have a memory function so that the main engine of the vehicle can maintain the switched state after the user switches the main fuel tank 101 and the auxiliary fuel tank 102 without automatically switching until the user switches again. When the user resets the vehicle main machine system, the oil supply is restored to the default main oil tank 101.

In addition, it should be noted that, in order to ensure the reliability of the use of the fuel supply structure, in a specific use, for example, when the vehicle power mode is OFF (i.e., the vehicle power is not powered on, and the entire vehicle network is in a sleep state) and the host system is not started, the user cannot operate the host system to switch between the main fuel tank 101 and the auxiliary fuel tank 102. In addition, when the power mode is ON (i.e., the vehicle system is started) and the host system is in the ON state, and the power mode is ON and the engine 2 is in the off state, the user can switch between the main fuel tank 101 and the sub fuel tank 102.

ON the other hand, when the power mode is ON and the engine 2 is in the start state, it is normally set that the user cannot switch between the main fuel tank 101 and the sub fuel tank 102. In this case, a prompt message such as "turn off the engine and then switch the fuel tank" may be displayed so that the user switches the main fuel tank and the sub fuel tank after turning off the engine.

In the present embodiment, in order to enable a user to know the amounts of oil in the main oil tank 101 and the auxiliary oil tank 102 in real time and to switch the oil tanks 1 in time when the amount of oil in the oil tank 1 is too low, as a preferred embodiment, an oil level detection module 8 is also provided in each oil tank 1. The oil level detection modules 8 in the oil tanks 1 are connected with the control module 7 and used for outputting current oil level signals of the oil tanks 1 to the control module 7, and each oil level detection module 8 can specifically adopt a liquid level sensor.

The present embodiment further provides a display module 9 in the vehicle, which is also connected to the control module 7, on the basis of the oil level detection module 8. At this time, the control module 7 can output a control instruction according to the current oil level signal sent by the oil level detection module 8, and the display module 9 outputs an oil amount prompt message matched with the control instruction so as to remind the user of paying attention to the oil amount in the oil tank 1.

The display module 9 may be a central control display screen or an instrument panel in the vehicle, and as one implementation form, the fuel amount prompt message matched with the control instruction may be, for example, a message indicating how much fuel is in the corresponding fuel tank 1, which means that the fuel amount prompt message identifies the current fuel level in the fuel tank 1. The current oil level of each oil tank 1 is detected by the oil level detection module 8, and the oil quantity information of each oil tank 1 is displayed to a user by the display module 9, so that the user can switch between the main oil tank 101 and the auxiliary oil tank 102 in time according to the oil quantities in the main oil tank and the auxiliary oil tank, and the situation that the vehicle cannot run due to insufficient oil quantity in the oil tank 1 in use is avoided.

Besides displaying the amount of oil, as another implementation form, the oil amount prompt message may also include an oil amount alarm prompt message. At this moment, when oil level detection module 8 detects that the oil level of oil tank 1 at the place is too low, output too little alarm instruction of oil mass to display module 9 through control module 7, display module 9 shows alarm information to remind the user to switch oil tank 1 and switch. It is worth mentioning that the oil quantity alarm threshold value can adopt an oil quantity alarm threshold value of an oil tank in the existing vehicle, and the alarm information displayed by the display module 9 can also adopt an oil quantity alarm form of the existing vehicle.

In the present embodiment, as an implementation form, on the basis of detecting the oil level in the oil tank 1, the user can more intuitively know the cruising range corresponding to the oil amount in the oil tank 1 being used. The display module 9 is also configured to be capable of outputting mileage information matched with the current oil level signal according to a control instruction of the control module 7. That is, the oil level detection module 8 detects the oil level, the oil level signal is transmitted to the control module 7, the control module 7 processes the oil level signal to obtain a vehicle driving range signal matched with the oil level signal, the vehicle driving range signal is transmitted to the display module 9, and the display module 9 displays the driving range signal to a user.

The control module 7 obtains the endurance mileage matched with the current oil level according to the current oil level by adopting related technical means in the prior art. In addition, as a preferred implementation form, the vehicle of this embodiment is further provided with an internet of vehicles module 10 connected to the control module 7, the internet of vehicles module 10 may be generally connected to the control unit 7 through a complete vehicle CAN bus, and the internet of vehicles module 10 may output the oil amount prompt information and the mileage information to the outside, so as to establish connection with an external cloud platform and a mobile phone of a user.

The vehicle accessible trigger module 6 output trigger signal of this embodiment makes control module 7 control diverter valve 3 carry out the oil circuit and switches, can select one of oil tank 1 for carrying out the fuel feeding to can show the oil mass in the oil tank 1 through display module 9, can send the warning when the oil level is low, also can show the continuation of the journey mileage that the oil mass corresponds in the oil tank 1 to the user, simultaneously, this vehicle also can be to user's cell-phone APP message routing, with show oil mass information and continuation of the journey mileage information etc. on user's cell-phone APP. From this, the vehicle of this embodiment can realize the independent fuel feeding of each oil tank 1, and can remind the user in time to carry out the switching of oil tank 1, and it can guarantee the reliability that the vehicle used, and has fine practicality.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
