Detailed Description
Embodiments of the present invention will be described in detail below, the embodiments described with reference to the drawings being illustrative, and the embodiments of the present invention will be described in detail below.
A fuel tank 1 according to an embodiment of the utility model is described below with reference to fig. 1 to 4, including: a case 100, an oil suction pipe 200, and a breakwater 300.
Specifically, the oil suction pipe 200 is provided to the case 100; the breakwater 300 is disposed in the tank body 100 and divides the internal space of the tank body 100 into the first chamber 110 and the second chamber 120, the oil suction pipe 200 is located in the first chamber 110, the breakwater 300 is provided with a through hole 310 and a one-way valve 320, the through hole 310 is located above the one-way valve 320, the through hole 310 communicates the first chamber 110 and the second chamber 120, and the one-way valve 320 allows fuel to flow from the bottom of the second chamber 120 to the bottom of the first chamber 110.
It should be noted that an oil suction pipe 200 is provided in the tank 100, so that the fuel in the tank 100 can be sucked out through the oil suction pipe 200 to be supplied to the engine for operation, thereby providing power output for the vehicle. Meanwhile, the anti-wave plate 300 is arranged in the fuel tank 1, so that fuel oil can be prevented from being turned over in the fuel tank 1, and the oil suction pipe 200 is safer when sucking the fuel oil in the fuel tank 1.
It can be understood that, during the traveling of the vehicle, the fuel circulating in the second chamber 120 of the tank 100 can flow into the first chamber 110 through the through hole 310 or the one-way valve 320 and can be sucked through the suction pipe 200, when the fuel in the fuel tank 1 has a relatively large amount, the liquid level in the fuel tank 1 is high, so that the fuel can flow in the first chamber 110 and the second chamber 120 mainly through the through hole 310, and thus the fuel tank 1 can contain more fuel; when the fuel in the fuel tank 1 is relatively low, the liquid level in the fuel tank 1 is low, and the fuel can only flow from the second chamber 120 to the first chamber 110 through the check valve 320, so that the fuel in the first chamber 110 can have a relatively high liquid level, and the fuel in the first chamber 110 can be adsorbed by the suction pipe 200. Or when the fuel in the vehicle is relatively less, the fuel tank 1 may be longitudinally reversed, so that the fuel on both sides of the tank 100 can flow into the first chamber 110 through the check valve 320, and the fuel in the first chamber 110 can maintain a relatively high liquid level, thereby providing a higher use efficiency of the fuel.
According to the fuel tank 1 of the embodiment of the utility model, the check valve 320 is arranged on the breakwater plate 300, when the fuel in the fuel tank 1 is relatively less, the check valve 320 can transfer the fuel in the second chamber 120 to the first chamber 110, so that the oil suction pipe 200 can suck enough fuel from the tank body 100 for use, and the fuel utilization efficiency of the fuel tank 1 is improved.
In some embodiments, the distance from the lowest point of the check valve 320 to the bottom wall of the box 100 is L1, and L1 satisfies the relationship: l1 is more than or equal to 0 and less than or equal to 2 cm.
It can be understood that when the fuel in the tank 100 is insufficient, the closer the one-way valve 320 is located to the bottom wall of the tank 100, the more the fuel in the second chamber 120 can flow into the first chamber 110 for the suction pipe 200 to suck. Thus, setting the distance from the lowest point of the check valve 320 to the bottom wall of the tank 100 to be less than 2cm enables the fuel in the second chamber 120 to flow more sufficiently into the first chamber 110, thereby improving the fuel efficiency in the fuel tank 1.
In particular embodiments, the axis of the check valve 320 is located directly above the centerline of the length of the tank 100. That is, the position of the check valve 320 is located at the middle in the width direction of the case 100. In this way, the distance from the check valve 320 to the oil suction pipe 200 is relatively low, so that the fuel in the second chamber 120 can be sucked by the oil suction pipe 200 more quickly after the fuel circulates to the first chamber 110 through the check valve 320, and the fuel utilization rate is improved.
In some embodiments, as shown in fig. 4, there are a plurality of through holes 310, and the through holes 310 are spaced on the breakwater 300 and all located above the one-way valve 320. In the description of the present invention, "a plurality" means two or more. Since the through hole 310 is formed above the check valve 320, when fuel is relatively sufficient, the fuel can be circulated through the through hole 310, so that the fuel contained in the fuel tank 1 can be more easily used. Moreover, the plurality of through holes 310 can increase the circulation efficiency of fuel oil, so that the utilization efficiency of the fuel oil is improved. Meanwhile, the through hole 310 is arranged above the check valve 320, so that the situation that the fuel flows from the second cavity 120 to the first cavity 110 through the check valve 320 and then flows from the first cavity 110 to the second cavity 120 through the through hole 310 can be avoided, and the fuel tank 1 still has high fuel utilization efficiency when the fuel in the fuel tank 1 is insufficient.
In some embodiments, as shown in fig. 4, the distance from the lowest point of the through hole 310 located at the lowest position to the bottom wall of the box 100 is L2, the height of the breakwater 300 is L3, and L2 and L3 satisfy the following relation: l2 is more than or equal to 0.1L3 and less than or equal to 0.5L 3. It will be appreciated that if the distance from the lowest point of the lowest through hole 310 to the bottom wall of the tank 100 is too large, the fuel will be concentrated to the first chamber 110 when there is relatively more fuel in the fuel tank 1, and the use performance of the fuel tank 1 will be wasted: if the distance from the lowest point of the lowest through hole 310 to the bottom wall of the tank 100 is too small, the fuel cannot flow from the second chamber 120 to the first chamber 110 well when the fuel is small, and the utilization efficiency of the fuel is reduced. Therefore, the relation between the distance L2 from the lowest point of the lowest through hole 310 to the bottom wall of the box body 100 and the height L3 of the breakwater plate 300 is set to be 0.1L3 and L2 and 0.5L3, so that when fuel is low in the fuel tank 1, the fuel can flow into the first cavity 110 from the second cavity 120 for use, and the fuel tank 1 has relatively high fuel utilization rate.
In some specific embodiments, the diameter of the through-hole 310 is greater than the diameter of the one-way valve 320. It will be appreciated that the fuel in the fuel tank 1 is relatively rich when the fuel is circulated through the through-hole 310. Therefore, the diameter of the through hole 310 is larger than that of the check valve 320, so that fuel can conveniently circulate, and when the fuel quantity in the fuel tank 1 is relatively low, the liquid level of the fuel in the fuel tank 1 is low, so that the requirement can be met by setting the diameter of the check valve 320 to be relatively small, and the production cost of the fuel tank 1 can be reduced.
In some embodiments, as shown in fig. 4, the breakwater board 300 is provided with flanges 330 at the peripheral edges, and the flanges 330 are welded and fixed to the inner peripheral wall of the box 100. It can be understood that the flange 330 can increase the contact area of the edge of the breakwater 300, so that the connection between the breakwater 300 and the tank 100 is more stable, and the breakwater 300 can more reliably prevent the fuel from turning over in the tank 100, thereby improving the usability of the fuel tank 1. In order to provide a more reliable partition sealing effect between the tank 100 and the breakwater 300, a circle of the flange 330 is usually welded to the inner peripheral wall of the tank 100, so that not only is the connection stability between the breakwater 300 and the tank 100 improved, but also a gap between the flange 330 and the tank 100 can be avoided, so that when fuel is less in the tank 100, the one-way valve 320 can better control the circulation of the fuel, and the use performance of the fuel tank 1 is improved.
In some embodiments, as shown in fig. 1 to 3, the two breakwaters 300 are distributed on both sides of the oil suction pipe 200, and the two breakwaters 300 separate the first chamber 110. Thus, two breakwaters 300 are provided in the tank 100 to divide the accommodation space of the tank 100 into a first cavity 110 and two second cavities 120 disposed at both sides of the first cavity 110, and when the fuel amount in the fuel tank 1 is small, the fuel can flow to the first cavity 110 through the second cavities 120 at both sides, so that the flow efficiency of the fuel flowing into the first cavity 110 is improved, and the fuel tank 1 has a higher fuel utilization rate. Meanwhile, when the fuel tank 1 is turned lengthwise, there is always a flow of the fuel in the second chamber 120 into the first chamber 110 through the check valve 320, so that the efficiency of utilizing the fuel in the fuel tank 1 is improved.
In some embodiments, as shown in fig. 3, the case 100 is provided with a concave oil accumulation groove 130, and the oil suction pipe 200 is positioned above the oil accumulation groove 130. It can be understood that when the amount of fuel in the first chamber 110 is small, the fuel in the first chamber 110 can be circulated to the oil collecting groove 130 to facilitate the suction of the oil suction pipe 200, thereby facilitating the suction use of the fuel in the fuel tank 1 and improving the fuel utilization efficiency of the fuel tank 1.
A vehicle according to an embodiment of the present invention includes: a fuel tank 1 as defined in any one of the above. Thus, by arranging the fuel tank 1 in the vehicle, when fuel in the fuel tank 1 is relatively less, the fuel can flow from the second chamber 120 to the first chamber 110 through the check valve 320, so that the oil suction pipe 200 can still suck sufficient fuel for use, the utilization efficiency of the fuel in the fuel tank 1 is improved, and the use performance of the vehicle is improved.
