Description

Technical Field

[0001] The utility model relates to a fuel tank for an all-terrain vehicle, in particular to a fuel tank for an all-terrain vehicle which can ensure the fuel storage capacity of the fuel tank and the overall rigidity of the fuel tank, and can facilitate the installation of a fuel pump and a fuel meter. Background Art

[0002] like Figure 1 As shown, the all-terrain vehicle is provided with a fuel tank 1 for storing fuel for combustion of the engine system in front of the seat cushion, and a refueling port 11 for adding fuel is provided on the top of the fuel tank 1. A fuel pump 13 is provided in the fuel tank 1 for extracting fuel in the fuel tank 1 to supply the engine system. The fuel pump 13 is installed on the fuel tank 1. A mounting port 12 is opened on the rear of the vehicle body from the refueling port 11. The fuel pump 13 is installed on the mounting port 12 and extends into the fuel tank 1. The fuel pump 13 is modularly provided with a fuel gauge 14 for measuring the fuel reserve in the fuel tank 1. The fuel gauge 14 can measure the fuel reserve as the fuel in the fuel tank 1 is consumed, and display it in the instrument that displays the vehicle information, thereby reminding the driver to pay attention to the fuel reserve in the fuel tank 1, thereby ensuring driving safety.

[0003] like Figure 1 As shown, the fuel pump 13 and the fuel gauge 14 are a modular component, so the overall width of the fuel pump 13 and the fuel gauge 14 is of a certain width. Therefore, when the modular fuel pump 13 and the fuel gauge 14 extend from the mounting opening 12 into the fuel tank 1, the mounting opening 12 must have a relatively large diameter to facilitate the installation of the modular fuel pump 13 and the fuel gauge 14; thus, the upper top of the fuel tank 1 has the fuel filling port 11 and the mounting opening 12 of a relatively large diameter, thereby weakening the overall rigidity of the upper top of the fuel tank 1.

[0004] Therefore, how to provide a fuel tank for an all-terrain vehicle to solve the disadvantage that the top end of the fuel tank is weakened due to the installation of the fuel pump and the fuel gauge has become an urgent issue to be solved by all-terrain vehicle manufacturers.

[0073] like Figure 3 , 4, 5, and 6, after the fuel pump 8 is installed through the installation port 44, the filter 8a (i.e., the fuel pump 8 suction port) for the fuel pump 8 to absorb the fuel inside the fuel tank 4 is located at the second step difference portion 46, thereby ensuring that the position where the fuel pump 8 absorbs the fuel is located at the lowest position of the fuel tank 4, thereby ensuring the effect of the fuel pump 8 sucking the fuel; the fuel gauge 9 is installed by inserting the fuel tank 4 through the installation hole 451 from the bottom of the vehicle body to the top of the vehicle body; the fuel gauge 9 has a mounting seat 91 and a metering portion 92 extending upward from the mounting seat 91 ; The mounting seat 91 is provided with a lock mounted on the mounting hole 451, and the mounting seat 91 has a leak-proof pad 911 to prevent the fuel in the fuel tank 4 from leaking out of the mounting seat 91; the metering portion 92 has a rod body 921 and a floating body 922 slidably mounted on the rod body 921; one end of the rod body 921 is penetrated on the mounting seat 91, and the rod body 921 is provided with a sliding rod portion 9211 with a smaller diameter at the end away from the mounting seat 91, and a stopper portion 9212 with a larger diameter is provided at the upper end of the sliding rod portion 9211, and the floating body 922 is penetrated on the sliding rod portion 9211, and more Specifically, the floating body 922 slides up and down between the lower end of the slide bar 9211 and the stopper 9212 along with the fuel storage amount in the fuel tank 4 to measure the fuel amount in the fuel tank 4. The floating body 922 and the slide bar 9211 can measure by resistance or electromagnetic methods. Furthermore, the fuel gauge 9 is connected to the instrument (not shown) of the all-terrain vehicle 2 for displaying the vehicle information. Since the fuel pump 8 and the fuel gauge 9 are independent components and are installed in the fuel tank 4 in a staggered manner, the fuel pump 8 and the fuel gauge 9 are connected to the fuel tank 4 in a staggered manner. On the upper side (the upper top side 4a) and the lower side (the bottom side 4b) of the fuel tank 4, more specifically, the upper side of the fuel gauge 9 corresponds to the raised portion 41 of the upper top side 4a, and the fuel pump 8 corresponds to the second step portion 46 of the bottom side 4b. Accordingly, the fuel tank 4 of the utility model does not need to have a large-diameter installation opening for installing the fuel pump 8 and the fuel gauge 9. Therefore, the overall rigidity of the fuel tank 4 of the utility model can be effectively maintained. It is worth mentioning that the convenience of the installation of the fuel pump 8 and the fuel gauge 9 can be further improved.

[0074] The utility model mainly relies on that the all-terrain vehicle 2 has a frame unit 3, and the frame unit 3 is locked with the fuel tank 4 that can provide the fuel storage for the power unit 6 to burn; the fuel tank 4 is installed with the fuel pump 8 and the fuel gauge 9, which are independent components respectively, and the fuel pump 8 and the fuel gauge 9 are installed on the fuel tank 4 in a separate and staggered manner; thereby, the fuel storage capacity of the fuel tank 4 and the overall rigidity of the fuel tank 4 can be ensured, and the installation of the fuel pump 8 and the fuel gauge 9 is convenient.
