Description

Technical Field

[0001] This utility model relates to the field of anti-theft fuel tank technology, and in particular to a car fuel tank with anti-theft function. Background Technology

[0002] The fuel tank is the core component for storing fuel. It is usually installed between the cab and the cargo box of a truck. Due to the high value of fuel and the fact that the fuel tanks of large trucks are exposed and easy to steal, the fuel tanks of some trucks parked at service areas or on the roadside are easily stolen. Common methods used by fuel thieves include: forcibly prying open the fuel tank cap lock and inserting a special hose to siphon the fuel from the tank.

[0003] As shown in the reference case "Anti-theft Fuel Tank" (publication number CN221188133U), one of the following components—a primary mechanical anti-theft component, a secondary mechanical anti-theft component, or an anti-theft alarm component—can be used alone to effectively prevent fuel thieves from stealing fuel. Using a combination of the primary and secondary mechanical anti-theft components can more effectively prevent fuel thieves from inserting the fuel-stealing pipe into the fuel tank to siphon fuel, resulting in a better anti-theft effect.

[0004] The aforementioned application prevents fuel thieves from inserting a primary and secondary anti-theft component inside the fuel filler neck to prevent fuel thieves from inserting the fuel-stealing pipe into the fuel tank, thereby preventing fuel theft from the tank. However, if the fuel thieves completely destroy the fuel filler neck, the fuel tank will not be able to provide any protection. Utility Model Content

[0005] Therefore, it is necessary to provide a car fuel tank with anti-theft function to address the problem of the fuel filler neck being completely destroyed.

[0006] A car fuel tank with anti-theft function includes: a tank body, a fuel filler port on the surface of the tank body, and a tank cover at the end of the fuel filler port away from the tank body;

[0007] An anti-theft mechanism includes a protective shell fixedly connected to the other end of the fuel filler neck. The protective shell is connected to the fuel filler neck. The cross-section of the protective shell is rectangular and horizontally arranged inside the housing. The protective shell is provided with a first barrier and two second barriers inside.

[0008] In one embodiment, the first barrier is fixedly connected to the inner bottom wall of the protective shell, and the first barrier is cylindrical.

[0009] In one embodiment, a guide block is fixedly connected to the middle of the inner bottom wall of the protective shell, the first barrier passes through the guide block, and the cross-section of the guide block is an isosceles triangle.

[0010] In one embodiment, two second nets are respectively disposed at both ends of the guide block, the second nets are fixedly connected to the inner wall of the protective shell, and the area of ​​the second nets is equal to the cross-sectional area inside the protective shell.

[0011] In one embodiment, an oil outlet is provided on the side of the second barrier away from the first barrier. The oil outlet is located on the lower surface of the protective shell, and the protective shell is connected to the interior of the box through the oil outlet.

[0012] In one embodiment, a base is provided below the box, and a lifting plate is slidably connected inside the base, the lifting plate being fixedly connected to the lower surface of the box.

[0013] In one embodiment, a plurality of telescopic rods are provided between the lower surface of the lifting plate and the inner bottom wall of the base, and the plurality of telescopic rods are respectively provided at the four corners of the lifting plate.

[0014] In one embodiment, a pressure sensor is provided between the lifting plate and the inner bottom wall of the base, and the pressure sensor is located at the center of the lifting plate.

[0015] Beneficial effects

[0016] 1. By installing a protective shell inside the fuel tank and a double-layer mesh inside the protective shell, when fuel thieves insert a hose into the fuel tank, the hose will be blocked by the protective shell and cannot directly contact the fuel inside the tank. Furthermore, even if fuel thieves forcibly break the filler neck, the protective shell will still remain inside the fuel tank and cannot be damaged, so fuel thieves will still be unable to extract the fuel from the tank. This greatly increases the difficulty for fuel thieves to steal fuel and thus improves the protection of the fuel inside the fuel tank.

[0017] 2. By placing the fuel tank on the lifting plate of the base and installing a pressure sensor between the lifting plate and the base, when a fuel thief directly and violently damages the tank, causing the fuel to leak, the overall weight of the fuel tank will decrease, thereby triggering the pressure sensor to alert the driver through an alarm, thus increasing the protection of the fuel tank.

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0031] The following is combined with Figures 1-5 This invention describes a car fuel tank with anti-theft function.

[0032] In one embodiment, a car fuel tank with anti-theft function includes: a tank body 100, a fuel inlet 110 provided on the surface of the tank body 100, and a tank cover 200 provided at the end of the fuel inlet 110 away from the tank body 100.

[0033] Anti-theft mechanism 300 includes a protective shell 310 fixedly connected to the other end of the fuel filler neck 110. The protective shell 310 is in communication with the fuel filler neck 110. The protective shell 310 has a rectangular cross-section and is horizontally arranged inside the housing 100. The protective shell 310 is provided with a first mesh 311 and two second meshes 313 inside.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the first barrier 311 is fixedly connected to the inner bottom wall of the protective shell 310. The first barrier 311 is cylindrical. A guide block 312 is fixedly connected to the middle of the inner bottom wall of the protective shell 310. The first barrier 311 passes through the guide block 312. The cross-section of the guide block 312 is an isosceles triangle. Two second barriers 313 are respectively set at both ends of the guide block 312. The second barriers 313 are fixedly connected to the inner wall of the protective shell 310. The area of ​​the second barriers 313 is equal to the cross-sectional area inside the protective shell 310. An oil outlet 314 is provided on the side of the second barriers 313 away from the first barrier 311. The oil outlet 314 is located on the lower surface of the protective shell 310. The protective shell 310 is connected to the inside of the box 100 through the oil outlet 314.

[0035] In this embodiment, when refueling is required, the fuel tank can be opened and fuel can be added directly to the fuel filler 110 through the fuel nozzle or other tools. The fuel entering the fuel filler 110 will fall to the middle of the guide plate, flow to both sides through the slope of the guide plate and through the mesh of the first barrier 311 and the second barrier 313, and enter the fuel tank through the fuel outlet 314. At the same time, the protective shell 310 is provided with a recessed area at the fuel outlet 314 to reduce fuel residue in the protective shell 310. Therefore, the anti-theft mechanism 300 of this device will not affect the normal use of the fuel tank. However, it should be noted that when the driver parks the vehicle, the fuel level line should be below the protective shell 310 to prevent fuel thieves from stealing fuel directly from the protective shell 310. However, because the protective shell 310 is located near the top of the fuel tank, and trucks are usually used for long-distance travel, when the driver needs to rest during normal driving, the fuel interface will be below the protective shell 310.

[0036] When the driver is driving normally, the pressure sensor 323 should be turned off to prevent accidental alarm triggering due to fuel consumption. The pressure sensor 323 should be turned on when parking. The pressure sensor 323 senses pressure changes generated by the lifting plate 321 through a pressure-sensitive element. The pressure causes deformation of the element, leading to changes in resistance and capacitance parameters. After amplification, filtering, and compensation by the signal processing circuit, a standard electrical signal is output. The processed pressure signal is compared with a preset alarm threshold. When the pressure is abnormal, the alarm circuit triggers a relay switch, driving the audible and visual alarm and the instrument panel indicator lights.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, a base 320 is provided below the box body 100. A lifting plate 321 is slidably connected inside the base 320. The lifting plate 321 is fixedly connected to the lower surface of the box body 100. Multiple telescopic rods 322 are provided between the lower surface of the lifting plate 321 and the inner bottom wall of the base 320. The multiple telescopic rods 322 are respectively provided at the four corners of the lifting plate 321. A pressure sensor 323 is provided between the lifting plate 321 and the inner bottom wall of the base 320. The pressure sensor 323 is located at the center of the lifting plate 321.

[0038] In this embodiment, the telescopic rod 322 is composed of a positioning rod, a lifting rod, a spring, and a connecting block. The positioning rod is fixedly connected to the inner bottom wall of the base 320, the lifting rod is slidably connected to the inner wall of the positioning rod, a spring is fixedly connected between the inner bottom wall of the positioning rod and the bottom end of the lifting rod, and the top end of the lifting rod is fixedly connected to the lower surface of the lifting plate 321 through the connecting block.

[0039] Working principle: When the fuel thief inserts the hose into the fuel tank through the filler port 110, the hose will be inserted into the first barrier 311 after entering the tank body 100. The hose in the first barrier 311 will be restricted inside the first barrier 311 and cannot continue to move to both ends of the protective shell 310, thereby preventing the hose from contacting the fuel in the tank body 100.

[0040] When oil thieves damage the refueling port 110 and the first barrier 311 by violent means or break through the first barrier 311 through a small-diameter hose, the barriers on both sides of the protective shell 310 will continue to block the hose, thereby preventing the hose from being inserted into the interior of the housing 100.

[0041] When a fuel thief damages the fuel tank by force, the leakage of fuel inside the tank will cause a change in the overall weight of the tank. As the overall weight of the tank decreases, the telescopic rod 322 will push the spring to move upward, thereby causing the lifting plate 321 to move upward. This reduces the pressure of the lifting plate 321 on the pressure sensor 323. When the pressure sensor 323 senses the change in the weight of the lifting plate 321, it will sound an alarm to warn the driver and simultaneously alert the fuel thief, thus intimidating the fuel thief and causing him to flee.

[0042] It should be noted that the pressure sensor 323 and telescopic rod 322 mentioned above are both devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the pressure sensor 323 is powered by the truck's built-in power supply.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
