In addition, the terms "first" and "second" in the embodiments of the present application are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance.
[0037] The oil storage barrel assembly, fuel tank assembly and vehicle of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments and implementations can be combined with each other.
[0038] See also Figure 1 As shown, an embodiment of the present application provides a vehicle, including a fuel tank assembly 100. The vehicle may be a heavy truck or other vehicle types, and the present application does not limit this. The fuel tank assembly 100 mainly includes a fuel tank 10 and an oil storage barrel assembly 20. The oil storage barrel assembly 20 mainly includes a top cover 21 and an oil storage barrel 22. The top cover 21 may be a flange plate installed on the top surface of the fuel tank 10. The oil storage barrel 22 is arranged inside the fuel tank 10 and can be movably connected to the bottom of the top cover 21. The fuel tank 10 is also provided with a filling port 11 for filling fuel into the fuel tank 10.
[0039] The fuel tank assembly 100 further includes a first oil inlet pipe 30 and a second oil inlet pipe 40. One end of the first oil inlet pipe 30 is connected to the oil storage barrel 22, and the other end extends to the front end of the fuel tank 10, so as to transport the fuel at the front end of the fuel tank 10 to the oil storage barrel 22. One end of the second oil inlet pipe 40 is connected to the oil storage barrel 22, and the other end extends to the rear end of the fuel tank 10, so as to transport the fuel at the rear end of the fuel tank 10 to the oil storage barrel 22. Since the cross-section of the oil storage barrel 22 is smaller than that of the fuel tank 10, through the above arrangement, no matter when the vehicle is in a low liquid level uphill or downhill situation, the fuel at the two ends of the fuel tank 10 at a low level can be sucked into the oil storage barrel 22 through at least one of the first oil introduction pipe 30 and the second oil introduction pipe 40, so that the fuel in the oil storage barrel 22 is in a full liquid state in real time, ensuring that the fuel in the fuel tank 10 is fully utilized, thereby ensuring that the first oil introduction pipe 30 and the second oil introduction pipe 40 are in full contact with the fuel until the fuel in the fuel tank 10 and the oil storage barrel 22 are consumed to the minimum value, thereby solving the problem of insufficient power and flameout of the vehicle when going uphill or downhill at a low liquid level, improving fuel utilization and ensuring cruising range.
[0040] In some optional embodiments, the fuel tank assembly 100 further includes a first filter 31 and a second filter 41. The first filter 31 is disposed at one end of the first oil inlet pipe 30 away from the oil storage barrel 22, that is, located at the front end of the interior of the fuel tank 10, and is used to filter the fuel delivered to the oil storage barrel 22 through the first oil inlet pipe 30. The second filter 41 is disposed at one end of the second oil inlet pipe 40 away from the oil storage barrel 22, that is, located at the rear end of the interior of the fuel tank 10, and is used to filter the fuel delivered to the oil storage barrel 22 through the second oil inlet pipe 40.
[0041] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the oil storage barrel assembly 20 mainly includes a top cover 21, an oil storage barrel 22, a first ejection valve 23 and a second ejection valve 24. The top cover 21 is provided with an oil outlet pipe interface 211 and an oil return pipe interface 212, which are used to connect with a fuel pump, and the fuel pump is connected with the vehicle supply pipeline and the oil return pipeline, so as to realize the transportation between the fuel in the fuel tank and the engine. The oil storage barrel 22 is movably connected to the bottom of the top cover 21. An oil outlet connecting pipe 25 and an oil return connecting pipe 26 are connected between the oil storage barrel 22 and the top cover 21, the oil outlet connecting pipe 25 is connected to the oil outlet pipe interface 211 of the top cover 21, and the oil return connecting pipe 26 is connected to the oil return pipe interface 212 of the top cover 21, and the oil outlet connecting pipe 25 and the oil return connecting pipe 26 can be hoses for transporting fuel. The fuel pump is connected to the engine. When the engine needs to be supplied with fuel, the fuel in the oil storage barrel 22 can be delivered to the engine through the oil outlet connecting pipe 25 and the oil outlet pipe interface 211. Excess fuel can be returned to the oil storage barrel 22 through the oil return pipe interface 212 and the oil return connecting pipe 26. A cover plate 239 can be provided on the top of the oil storage barrel 22, and two interfaces for connecting the oil outlet connecting pipe 25 and the oil return connecting pipe 26 can be provided on the cover plate 239.
[0042] The barrel wall of the oil storage barrel 22 is also provided with a first oil inlet pipe interface 221 and a second oil inlet pipe interface 222. Figure 6 and Fig. 9 As shown, an oil outlet channel 226 and an oil return channel 223 are formed inside the oil storage barrel 22, wherein the oil outlet channel 226 communicates with the oil outlet pipe interface 211 and the inside of the oil storage barrel 22, and the oil return channel 223 communicates with the oil return pipe interface 212 and the inside of the oil storage barrel 22. The oil outlet channel 226 is integrated into the oil storage barrel 22, and the oil suction port is at the lowest position of the oil storage barrel 22, which can fully contact the fuel in the oil storage barrel 22. The fuel flowing through the oil outlet channel 226 reaches the oil outlet pipe interface 211 on the top cover 21 after passing through the oil outlet connecting pipe 25, which is the oil suction source of the vehicle supply pipeline.
[0043] Combination Figure 3 , Figure 5 and Figure 6As shown, the oil storage barrel assembly 20 also includes a first ejection valve 23 and a second ejection valve 24, both of which are arranged in the oil storage barrel 22. The first ejection valve 23 includes a first ejection valve cavity 231, the first ejection valve cavity 231 is connected to the first oil inlet pipe interface 221 and the interior of the oil storage barrel 22, and the first ejection valve 23 is used to suck the fuel outside the oil storage barrel 22 into the oil storage barrel 22 from the first oil inlet pipe interface 221. The second ejection valve 24 includes a second ejection valve cavity, the second ejection valve cavity is connected to the second oil inlet pipe interface 222 and the interior of the oil storage barrel 22, and the second ejection valve 24 is used to suck the fuel outside the oil storage barrel 22 into the oil storage barrel 22 from the second oil inlet pipe interface 222. It should be noted that the first ejection valve 23 and the second ejection valve 24 can adopt the same structure, Figure 6 The cross-sectional perspective of FIG. 1 takes the first injection valve 23 as an example.
[0044] Excess fuel can be returned to the oil storage barrel 22 through the oil return pipe interface 212 and the oil return connecting pipe 26. Through the action of the first injection valve 23, the fuel in the fuel tank 10 can be sucked into the oil storage barrel 22 through the first oil injection pipe interface 221 and the first injection valve cavity 231. Through the action of the second injection valve 24, the fuel in the fuel tank 10 can be sucked into the oil storage barrel 22 through the second oil injection pipe interface 222 and the second injection valve cavity. Regardless of whether the vehicle is in a low-liquid level uphill or downhill, the fuel at the two ends of the fuel tank 10 at a low level can be sucked into the oil storage barrel 22 through at least one of the first injection valve 23 and the second injection valve 24, so that the fuel in the oil storage barrel 22 is in a full liquid state in real time. Ensuring that the fuel in the fuel tank 10 is fully utilized solves the problem of insufficient power and flameout when the vehicle is uphill or downhill at a low liquid level, improves fuel utilization and ensures cruising range.
[0045] In some optional embodiments, combined with Figure 6 As shown, a first oil inlet passage 224 and a second oil inlet passage (not shown) are formed inside the oil storage barrel 22. The cross-sections of the first oil inlet passage 224 and the second oil inlet passage are both smaller than the cross-sections of the oil return passage 223. The heights of the first oil inlet passage 224 and the second oil inlet passage are both smaller than the height of the oil return passage 223. The first ejection valve chamber 231 is connected to the oil return passage 223, the first oil inlet passage 224, and the first oil inlet pipe interface 221. The second ejection valve chamber is connected to the oil return passage 223, the second oil inlet passage, and the second oil inlet pipe interface 222.
[0046] Excess fuel can be returned to the oil storage barrel 22 through the oil return pipe interface 212, the oil return connecting pipe 26, the first injection valve cavity 231 and the first oil introduction channel 224. Since the cross section of the first oil introduction channel 224 is smaller than the cross section of the oil return channel 223, during the oil return process, when the fuel flows from the oil return channel 223 of the thick pipe to the first oil introduction channel 224 of the thin pipe, it follows the law of fluid mechanics. Since the cross sections of the first oil introduction channel 224 and the second oil introduction channel are both smaller than the cross section of the oil return channel 223, the pipe narrows and the volume changes, the flow velocity of the fuel increases, and the pressure decreases, thereby forming a negative pressure in the first injection valve cavity 231, which is lower than the pressure outside the first oil introduction pipe interface 221. At this time, due to the pressure difference, the fuel in the fuel tank 10 will be sucked into the first injection valve cavity 231 through the first oil introduction pipe interface 221 and then flow into the oil storage barrel 22 through the first oil introduction channel 224. Similarly, due to the pressure difference, the fuel in the fuel tank 10 can also be sucked into the second injection valve cavity through the second oil inlet pipe interface 222 and then flow into the oil storage barrel 22 through the second oil inlet channel. This process can increase the amount of fuel returned to the oil storage barrel 22, so that the fuel in the oil storage barrel 22 is in a full liquid state in real time.
[0047] Furthermore, combined with Figure 7 and Figure 8 As shown, the first ejection valve cavity 231 includes a first cavity 232, a second cavity 233 and a third cavity 234. The first cavity 232 is arranged in the transverse direction, the second cavity 233 and the third cavity 234 are arranged in the longitudinal direction and are both connected to the first cavity 232. The first cavity 232 is connected to the first oil inlet pipe interface 221, the second cavity 233 is connected to the oil return channel 223, and the third cavity 234 is connected to the first oil inlet channel 224. The cross section of the second cavity 233 is larger than the cross section of the third cavity 234. The first ejection valve 23 may include a first valve body 235, a second valve body 236 connected to the first valve body 235, and a third valve body 237. The first valve body 235 has a first cavity 232 and is plugged and matched with the first oil inlet pipe interface 221. The second valve body 236 has a second cavity 233 and is plugged and matched with the oil return channel 223. The third valve body 237 has a third cavity 234 and is plug-fitted with the first oil introduction passage 224 .
[0048] It can be understood that the first ejection valve 23 adopts a Venturi valve, and the Venturi effect is completed in the first ejection valve chamber 231. When a certain amount of fuel flows through the first ejection valve chamber 231 during the oil return process, the fuel in the first oil inlet pipe interface 221 can be sucked into the first ejection valve chamber 231, which can increase the fuel flow in the first oil inlet channel 224.
[0049] Similarly, the second ejection valve cavity includes a fourth cavity, a fifth cavity and a sixth cavity. The fourth cavity is arranged in the horizontal direction, the fifth cavity and the sixth cavity are arranged in the longitudinal direction and are both connected to the fourth cavity. The fourth cavity is connected to the second oil inlet pipe interface, the fifth cavity is connected to the oil return channel 223, and the sixth cavity is connected to the second oil inlet channel. The second ejection valve 24 may include a fourth valve body, a fifth valve body connected to the fourth valve body, and a sixth valve body. The fourth valve body has a fourth cavity and is plugged and matched with the second oil inlet pipe interface. The fifth valve body has a fifth cavity and is plugged and matched with the oil return channel. The sixth valve body has a sixth cavity and is plugged and matched with the second oil inlet channel.
[0050] It can be understood that the second injection valve 24 can also adopt a Venturi valve. The Venturi effect is completed in the second injection valve cavity. When a certain amount of fuel flows through the second injection valve cavity during the oil return process, the fuel in the second oil inlet pipe interface 222 can be sucked into the second injection valve cavity, which can increase the fuel flow in the second oil inlet channel.
[0051] The oil storage tank assembly of the present application can form an oil return injection system by connecting the oil return channel, the first oil inlet channel and the first oil inlet pipe interface through the first injection valve. Another oil return injection system can be formed by connecting the oil return channel, the second oil inlet channel and the second oil inlet pipe interface through the second injection valve, thereby forming an oil return double injection system composed of the first injection valve and the second injection valve. Regardless of whether the current vehicle is in a low liquid level uphill or downhill, at least one injection valve can inject fuel from the fuel tank into the oil storage barrel, so that the fuel pipe in the oil storage barrel is submerged in oil in real time until the oil is consumed.
[0052] In some optional embodiments, the first oil inlet pipe interface 221 and the second oil inlet pipe interface 222 are both disposed at the bottom end of the side wall of the oil storage barrel 22. Figure 6 As shown, the bottom of the oil storage barrel 22 is formed with a first concave cavity 225 and a second concave cavity (not shown). The first ejection valve 23 is arranged in the first concave cavity 225, and is plugged and matched with the first oil inlet pipe interface 221 through the first valve body 235, plugged and matched with the oil return channel 223 through the second valve body 236, and plugged and matched with the first oil inlet channel 224 through the third valve body 237. The second ejection valve 24 is arranged in the second concave cavity, and is plugged and matched with the second oil inlet pipe interface 222 through the fourth valve body, plugged and matched with the oil return channel 223 through the fifth valve body, and plugged and matched with the second oil inlet channel through the sixth valve body 237. In addition, the bottom surface of the first ejection valve 23 and the bottom surface of the second ejection valve 24 are both flush with the bottom surface of the oil storage barrel 22, so that the oil storage barrel 22 can be easily installed in the fuel tank 10.
[0053] In some optional embodiments, the oil storage barrel 22 is provided with a plurality of guide portions 238, and the oil storage barrel assembly 20 further includes a guide rod 27 and an elastic member 28, one end of the guide rod 27 is fixedly connected to the top cover 21, and the other end of the guide rod 27 is movably inserted into the guide portion 238. The elastic member 28 is sleeved on the outside of the guide rod 27, and the two ends of the elastic member 28 are respectively abutted against the top cover 21 and the oil storage barrel 22. Before the oil storage barrel assembly 20 is installed in the fuel tank 10, the length of the guide rod 27 inserted into the guide portion 238 makes the elastic member 28 in a natural state, and the elastic member 28 can be compressed when the oil storage barrel assembly 20 is installed. When the top cover 21 of the oil storage barrel assembly 20 is installed on the top surface of the fuel tank 10, the oil storage barrel 22 abuts against the bottom surface of the inner wall of the fuel tank 10, the length of the guide rod 27 passing through the guide part 238 increases, and the oil storage barrel 22 and the top cover 21 squeeze the elastic member 28, so that the elastic member 28 is in a compressed state, which can provide sufficient pressure for the oil storage barrel 22, so that the oil storage barrel 22 is fully and firmly close to the bottom surface of the fuel tank 10. Optionally, the elastic member 28 can be a compression spring. The side wall of the oil storage barrel 22 can be evenly provided with a plurality of guide parts 238 along the circumferential direction. Accordingly, the number of the guide rods 27 and the elastic members 28 is the same as the number of the guide parts 238. One elastic member 28, one guide rod 27 and one guide part 238 are assembled with each other to form a guide assembly. When the oil storage barrel assembly 20 is installed, the top cover 21 and the oil storage barrel 22 are supported by multiple such guide assemblies, so that the force on the oil storage barrel 22 is more uniform, and a better support effect is achieved.
[0054] In some optional embodiments, the top cover 21 is further provided with a liquid level gauge plug-in 213, and the oil storage barrel assembly 20 further includes a reed switch 291 and a liquid level gauge float 292. The liquid level gauge float 292 is sleeved on the reed switch 291, and the reed switch 291 is located outside the oil storage barrel 22. One end of the reed switch 291 is connected to the liquid level gauge plug-in 213, and the other end extends to be flush with the bottom surface of the oil storage barrel 22. The liquid level gauge float 292 can be a hollow magnetic float that can rise or fall with the liquid level in the fuel tank 10. The reed switch 291 is a reed switch. When the liquid level gauge plug-in 213 slides on the reed switch 291, the internal reed switch is turned on, and different resistors are connected to the circuit, thereby outputting liquid level information of different liquid level heights. The reed switch 291 and the liquid level gauge float 292 form a liquid level detection structure for monitoring the liquid level of the fuel in the fuel tank 10. The liquid level gauge plug-in 213 is an interface connected to the vehicle wiring harness, and the internal pins are connected to the reed switch 291, and the liquid level signal is transmitted to the vehicle wiring harness through the liquid level gauge plug-in 213.
[0055] In some optional embodiments, combined with Figure 5 and Fig. 9As shown, a one-way valve interface 51 is also provided at the bottom of the oil storage barrel 22, and the oil storage barrel assembly 20 also includes a one-way valve 50, which is arranged in the oil storage barrel 22 and connected to the one-way valve interface 51. The one-way valve 50 is used to guide the fuel outside the oil storage barrel 22 from the one-way valve interface 51 into the inside of the oil storage barrel 22. The flow direction of the one-way valve 50 can only flow from the outside of the oil storage barrel 22 to the inside, and cannot flow out in the opposite direction. When the fuel pump is not started, when the liquid level of the fuel in the fuel tank 10 is higher than the liquid level of the fuel in the oil storage barrel 22, the fuel in the fuel tank 10 can enter the oil storage barrel 22 through the one-way valve 50 due to the liquid level difference. When the liquid levels of the two are the same, the one-way valve 50 is closed. Optionally, the one-way valve 50 can be an umbrella valve.
[0056] Furthermore, the oil storage barrel assembly 20 further includes an oil blocking grid 52, which is arranged on the bottom surface of the inner wall of the oil storage barrel 22, and the one-way valve 50 is located in the oil blocking grid 52. The oil blocking grid 52 extends along the height direction of the oil storage barrel 22 on opposite sides along the first direction to form an oil blocking portion 521, and the oil blocking grid 52 is formed with notch portions 522 on opposite sides along the second direction. The interior of the oil blocking grid 52 is connected to the interior of the oil storage barrel 22 through the notch portions 522. When the fuel pump is not started, when the liquid level of the fuel in the fuel tank 10 is higher than the liquid level of the fuel in the oil storage barrel 22, the fuel in the fuel tank 10 can enter the oil blocking grid 52 through the one-way valve 50 due to the liquid level difference, and then flow into the interior of the oil storage barrel 22 through the notch portions 522.
[0057] The working principle of the fuel tank assembly of this application is as follows:
[0058] When refueling, the fuel pump is not started, and fuel is added to the fuel tank 10 through the filling port 11. The fuel in the fuel tank 10 enters the oil storage barrel 22 through the one-way valve 50 until the liquid levels inside and outside the oil storage barrel 22 are flush. At this time, the fuel in the oil storage barrel 22 is the initial fuel. When the vehicle is started, under the action of the fuel pump, the fuel in the oil storage barrel 22 is delivered to the engine through the oil outlet channel 226, the oil outlet connecting pipe 25 and the oil outlet pipe interface 211.
[0059] The excess fuel enters the oil return channel 223 through the oil return pipe interface 212 and the oil return connecting pipe 26 in sequence. The fuel passing through the oil return channel 223 is divided into two paths. One path passes through the first injection valve cavity 231 of the first injection valve 23 and enters the first oil induction channel 224 to return to the oil storage barrel 22. The other path passes through the second injection valve cavity of the second injection valve 24 and enters the second oil induction channel to return to the oil storage barrel 22. In this process, the oil return double injection system is activated. The fuel at the front end of the fuel tank 10 can be sucked into the first injection valve cavity 231 through the first filter 31, the first oil induction pipe 30 and the first oil induction pipe interface 221 in sequence, and then enter the first oil induction channel 224 to return to the oil storage barrel 22. The fuel at the rear end of the fuel tank 10 can be sucked into the second injection valve cavity through the second filter 41, the second oil induction pipe 40 and the second oil induction pipe interface 222 in sequence, and then enter the second oil induction channel to return to the oil storage barrel 22. This process can amplify the amount of fuel returning to the oil storage barrel 22, so that the fuel in the oil storage barrel 22 is in a full liquid state in real time, so that no matter whether the vehicle is in an uphill or downhill condition, there is at least one set of oil return injection system to replenish the oil in the oil storage barrel, so that the oil outlet pipe 226 inside the oil storage barrel 22 can fully contact the oil when the liquid level is low and the oil is uphill or downhill, until the oil in the fuel tank 10 and the oil storage barrel 22 is consumed, thereby improving the fuel utilization rate. Taking a slope of 30% as an example, the fuel utilization rate can be increased from 86% to 98%, avoiding the hidden danger of insufficient power or even flameout due to poor oil absorption when the vehicle is in an uphill or downhill condition with a low liquid level.
