[0002] The fuel gauge, as a basic instrument, provides users with fuel level information. The fuel sensor, installed in the car's fuel tank, is a component used to measure changes in the fuel level. When the fuel level changes, the sensor's output resistance signal changes accordingly and is transmitted to the fuel gauge via a specific data signal line. By observing the fuel gauge, the driver can accurately grasp the fuel level information, make correct judgments, and take appropriate actions.

[0003] Existing fuel level detection devices primarily rely on floats that suspend the gasoline in the tank to detect its level. When there are many impurities in the fuel, these impurities can interfere with the sensor's detection, leading to significant errors and affecting the driver's ability to monitor fuel levels, causing inconvenience for users.

[0004] In view of this, we propose a vehicle fuel tank level detection device. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A vehicle fuel tank level detection device includes a fuel tank 1, a partition 2 movably inserted into the inner side of the fuel tank 1, a filter screen 3 disposed on the outer side of the partition 2, the partition 2 movably penetrating the fuel tank 1 and extending to the upper side, and a mounting plate 4 fixedly disposed on the upper part of the partition 2 located on the upper side of the fuel tank 1, a connecting plate 16 fixedly disposed on the outer side of the mounting plate 4, an installation mechanism for docking with the connecting plate 16 disposed on the upper side of the fuel tank 1, a limit rod 5 fixedly disposed on the inner side of the fuel tank 1 located on the inner part of the partition 2, a float 6 movably sleeved on the outer side of the limit rod 5, and a transmission mechanism for docking with the float 6 disposed on the upper side of the fuel tank 1. The sensor body 9 and the upper and lower sides of the oil tank 1 are respectively equipped with pressure sensor 7 and pressure sensor 8 on the upper and lower sides of the float plate 6. Pressure sensor 7 and pressure sensor 8 can detect the high and low points of the oil level. When the oil tank 1 is full, it will drive the float plate 6 to move upward and squeeze pressure sensor 7. When the oil in the oil tank 1 is about to run out, the float plate 6 will squeeze pressure sensor 8. The controller can get the pressure on pressure sensor 7 and pressure sensor 8 in time, so as to know in time whether the oil is full or the oil level is insufficient.

[0029] Specifically, the installation mechanism includes a mounting frame 10 fixedly mounted on the upper side of the oil tank 1. A lead screw 11 is rotatably mounted inside the mounting frame 10. Two threads in opposite directions are provided on the outer side of the lead screw 11, and threaded blocks 12 are fitted on both threads in opposite directions on the outer side of the lead screw 11. Connecting blocks 13 are fixedly mounted on the outer side of both sets of threaded blocks 12. The connecting blocks 13 movably pass through the mounting frame 10 and extend to the outer side. A mounting block 14 is fixedly mounted on the outer side of the connecting block 13 located outside the mounting frame 10. A locking block 15 is fixedly mounted on the inner side of the mounting block 14. The connecting plate 16 has slots 17 on both sides for engaging the locking blocks 15. Rotating the lead screw 11 in different directions can drive the locking blocks 15 to move in different directions, thereby facilitating the locking blocks 15 to engage in the slots 17 or to move them out of the slots 17. This facilitates the installation and disassembly of the connecting plate 16 and the mounting plate 4, improving the ease of loading and unloading the partition 2.

[0030] Furthermore, a worm gear 19 is rotatably provided inside the mounting frame 10. The worm gear 19 moves through the mounting frame 10 and extends to the outside. A turntable 20 is fixedly provided on the outer end of the worm gear 19 located on the outer part of the mounting frame 10. A worm wheel 18 is fixedly provided on the outer side of the lead screw 11. The worm wheel 18 meshes with the worm gear 19. By rotating the turntable 20 in different directions, the lead screw 11 can be driven to rotate in different directions, improving ease of use.

[0031] It is worth noting that a limiting block 21 is fixedly installed on the outer side of the threaded block 12, and a limiting groove 22 for engaging the limiting block 21 is opened on the inner side of the mounting frame 10. When the lead screw 11 rotates, it can drive the limiting block 21 to slide within the limiting groove 22, thereby enabling the threaded block 12 to move along the lead screw 11, further ensuring the movement stability of the threaded block 12.

[0032] It is worth noting that sealing blocks 23 are fixedly installed on both sides of the partition plate 2 on the lower side of the mounting plate 4, and two sets of sealing grooves 24 for mating sealing blocks 23 are opened on the upper side of the oil tank 1. When the mounting plate 4 is installed, the sealing blocks 23 are inserted into the sealing grooves 24 to improve the sealing effect of the mounting plate 4.

[0033] In addition, a gripping groove is provided on the upper side of the mounting plate 4, which makes it easy to pull the mounting plate 4 upward, further improving the ease of operation.

[0034] Working principle: First, the oil in the tank 1 enters the inner side of the baffle 2 through the filter screen 3. Impurities in the oil are filtered by the filter screen 3. The float 6 rises and falls with the rise and fall of the oil level. The sensor body 9 can detect the position of the float 6 and transmit the value to the instrument panel. When the filter screen 3 is blocked by impurities, the worm gear 19 can be rotated by rotating the turntable 20. The rotation of the worm gear 19 drives the worm wheel 18 and the lead screw 11 to rotate. At this time, the two sets of threaded blocks 12 sleeved on the outside of the lead screw 11 move simultaneously along the lead screw 11 under the limiting action of the limiting block 21 and the limiting groove 22. When the threaded blocks 12 move, they drive the connecting block 13 and the mounting block 14 to move. When the mounting block 14 moves, it drives the locking block 15 to move out of the locking groove 17 on the outside of the connecting plate 16. Then the mounting plate 4 can be pulled up. By pulling the mounting plate 4, the baffle 2 can be pulled out of the tank 1, which can quickly clean the impurities on the filter screen 3 and ensure the continuous filtering effect of the filter screen 3.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
