[0035] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0036] The fuel tank assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0037] like Figure 1-Figure 3 As shown, the oil tank assembly 100 according to one embodiment of the present invention includes: a first oil tank 1 , a second oil tank 2 and a baffle 3 .

[0038] like Figure 1-Figure 3 As shown, the first oil tank 1 has a first accommodating chamber 11 , and the first accommodating chamber 11 is used for storing oil.

[0039] For example, in Figure 1 In the embodiment shown, the first oil tank 1 is a rectangular oil tank, which is easy to manufacture and easy to place hydraulic components on.

[0040] like Figure 1 、 Figure 2 and Figure 4 As shown, the second oil tank 2 is located in the first accommodating chamber 11. The second oil tank 2 has a second accommodating chamber 21. The second oil tank 2 has an opening 22 that connects the first accommodating chamber 11 and the second accommodating chamber 21. Specifically, the second oil tank 2 has a second accommodating chamber 21, which is also used to store oil. The second oil tank 2 is provided with an opening 22. Since the second oil tank 2 is located in the first accommodating chamber 11 of the first oil tank 1, the second accommodating chamber 21 can be connected to the first accommodating chamber 11 through the opening 22, so that the oil in the first oil tank 1 and the oil in the second oil tank 2 can be combined. This arrangement facilitates the mutual circulation of the oil in the first oil tank 1 and the oil in the second oil tank 2. Among them, the volume of the second oil tank 2 is smaller than that of the first oil tank 1.

[0041] like Figure 1-Figure 5 As shown, the baffle 3 is used to open or close the opening 22. Specifically, by providing the baffle 3 at the opening 22, the user can control the baffle 3 to open or close the opening 22. When the baffle 3 is controlled to open the opening 22, the first accommodating chamber 11 and the second accommodating chamber 21 are connected, and the oil in the first fuel tank 1 and the second fuel tank 2 can flow into each other. When the baffle 3 is controlled to close the opening 22, the first accommodating chamber 11 and the second accommodating chamber 21 are disconnected, and the oil in the first fuel tank 1 and the second fuel tank 2 cannot flow into each other. In normal vehicle operation, the opening 22 is in the open state.

[0042] For example, in Figure 1-Figure 3 In the illustrated embodiment, the second fuel tank 2 is a rectangular tank with a relatively small bottom area. The opening 22 is rectangular, and the baffle 3 is also rectangular in shape, with the area of ​​the baffle 3 being larger than that of the opening 22. The opening 22 is sealed with the baffle 3, and equal volumes of oil are added to the first and second fuel tanks 1 and 2, respectively. Because the volume of the second fuel tank 2 is smaller than that of the first fuel tank 1 and the bottom area of ​​the second fuel tank 2 is smaller, the oil level in the second fuel tank 2 will be higher than that in the first fuel tank 1. When the vehicle leaves the factory, the opening 22 can be sealed with the baffle 3, and the oil required for basic driving can be added to the second fuel tank 2, reducing the amount of fuel required for new vehicles and lowering factory costs. When the oil level is low, oil can be added to the second fuel tank 2, allowing the vehicle to continue driving even with less oil.

[0043] According to the fuel tank assembly 100 of an embodiment of the present invention, the second fuel tank 2 is arranged in the first accommodating cavity 11 of the first fuel tank 1, an opening 22 connecting the second accommodating cavity 21 of the second fuel tank 2 and the first accommodating cavity 11 is provided on the second fuel tank 2, and a baffle 3 is provided to open or close the opening 22. When the vehicle leaves the factory, the baffle 3 closes the opening 22, and oil can be added to the second fuel tank 2, thereby reducing the minimum oil filling amount required when the vehicle leaves the factory, thereby greatly reducing costs.

[0044] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the second oil tank 2 is located at the bottom of the first accommodating chamber 11, and the opening 22 is located at the bottom of the second oil tank 2. This arrangement allows the oil at the bottom of the first accommodating chamber 11 and the second accommodating chamber 21 to be fully utilized.

[0045] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the bottom wall of the first accommodating chamber 11 is flush with the bottom wall of the second accommodating chamber 21, and the lower edge of the opening 22 is flush with the bottom wall of the first accommodating chamber 11. This arrangement allows the oil at the bottom of the first accommodating chamber 11 and the second accommodating chamber 21 to flow fully, further improving the utilization of the oil.

[0046] It should be noted that the bottom wall of the first accommodating cavity 11 may not be flush with the bottom wall of the second accommodating cavity 21 , and the lower edge of the opening 22 may not be flush with the bottom wall of the first accommodating cavity 11 .

[0047] According to some embodiments of the present invention, Figure 2-Figure 6As shown, opening 22 is provided on the side wall of second fuel tank 2, and a guide hole 12 is provided on the top wall of first fuel tank 1. Fuel tank assembly 100 also includes a drive rod 31, which extends through guide hole 12. One end of drive rod 31 is connected to baffle 3 and is used to drive baffle 3 to open or close opening 22. Specifically, opening 22 is provided at the lower end of the side wall of second fuel tank 2. One end of drive rod 31 is connected to baffle 3, and the other end extends through guide hole 12 on the bottom wall of first fuel tank 1. A user can drive baffle 3 to close or open opening 22 by moving the guide rod located on the outside of first fuel tank 1. This arrangement is simple in structure and easy to operate.

[0048] For example, in Figure 3 In the illustrated embodiment, when the driving rod 31 moves upward, the opening 22 can be opened, and when the driving rod 31 moves downward, the opening 22 can be closed.

[0049] According to some embodiments of the present invention, Figure 3 As shown, a sealing ring 4 is provided between the driving rod 31 and the guide hole 12. By providing the sealing ring 4, oil leakage can be prevented, thereby improving the sealing performance of the first oil tank 1.

[0050] Optionally, the sealing ring 4 may be a rubber piece.

[0051] According to some embodiments of the present invention, the guide rod and the sealing ring 4 are in an interference fit, so that the guide rod can be limited by friction after moving, thereby fixing the position of the guide rod and improving the stability of the oil tank assembly 100.

[0052] According to some embodiments of the present invention, Figures 1-6 As shown, there are two openings 22, one on each of the two opposite walls of the second oil tank 2, and two baffles 3, one corresponding to each of the two openings 22. This arrangement facilitates the flow of oil in the first accommodating chamber 11 and the second accommodating chamber 21, allowing for full utilization of the oil. It also has a simple structure and is easy to operate.

[0053] For example, in Figure 3 In the illustrated embodiment, openings 22 are provided on both the left and right side walls of the second fuel tank 2. Baffles 3 are provided on both openings 22. A drive rod 31 is connected to each of the two baffles 3 and then passed through the guide hole 12. Alternatively, there may be two drive rods 31 and two guide holes 12, with two drive rods 31 connected to each of the two baffles 3 and then passed through the corresponding guide holes 12.

[0054] It should be noted that openings 22 may also be provided on other side walls of the second oil tank 2 , and corresponding baffles 3 may also be provided.

[0055] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the bottom wall of the first fuel tank 1 has an oil drain port 13, which is sealed with a plug 14. This arrangement allows the user to close the opening 22 of the second fuel tank 2 if the fuel level is too low while driving, open the plug 14 at the oil drain port 13, collect the remaining oil in the first fuel tank 1 using a container, and then inject the oil into the second fuel tank 2. This significantly raises the oil level, allowing the vehicle to continue traveling for a distance. The plug 14 prevents oil leakage from the oil drain port 13, thereby improving the sealing performance of the first fuel tank 1.

[0056] According to some embodiments of the present invention, Figure 1-Figure 3 As shown, the top wall of the first fuel tank 1 has a fuel filling port 15, and the top of the second fuel tank 2 is open, with the fuel filling port 15 facing the open top opening 22 of the second fuel tank 2. This arrangement facilitates direct injection of oil from the fuel filling port 15 into the second fuel tank 2. When the vehicle rolls off the assembly line, the opening 22 of the second fuel tank 2 is closed, and the fuel required for basic driving is added to the second fuel tank 2. This can reduce the amount of fuel required for new vehicles leaving the factory and reduce factory costs.

[0057] It should be noted that the oil filling port 15 may not be opposite to the top open port 22 of the second oil tank 2 , and a conduit may be used to introduce the oil poured from the oil filling port 15 into the second oil tank 2 .

[0058] The following describes a vehicle according to an embodiment of the present invention with reference to the accompanying drawings.

[0059] According to the vehicle of the embodiment of the present invention, including the above-mentioned fuel tank assembly 100, the fuel inlet pipe 5 and the fuel return pipe 6 of the vehicle's engine are arranged in the second accommodating chamber 21. This arrangement allows the second fuel tank 2 to provide fuel to the vehicle even after the opening 22 is closed.

[0060] According to the vehicle of the embodiment of the present invention, the second fuel tank 2 is arranged in the first accommodating chamber 11 of the first fuel tank 1, an opening 22 connecting the second accommodating chamber 21 of the second fuel tank 2 and the first accommodating chamber 11 is provided on the second fuel tank 2, and a baffle 3 is provided to open or close the opening 22. When the vehicle leaves the factory, the baffle 3 closes the opening 22, and oil can be added to the second fuel tank 2, thereby reducing the minimum oil filling amount required when the vehicle leaves the factory, thereby greatly reducing costs.
