[0016] This utility model provides a technical solution: a fuel tank cap locking structure, including a fuel tank cap lock body 1. A mounting bracket 16 is fixedly connected to the outer side of the fuel tank cap lock body 1. The mounting bracket 16 is fixed to the fuel tank cap by locking screws, thereby fixing the position of the fuel tank cap lock body 1. A hinged cover 15 is rotatably connected to one end of the fuel tank cap lock body 1. A rotating shaft and a steel ball spring are provided at one end of the hinged cover 15, allowing it to automatically reset and close after being opened. The hinged cover 15 is used to cover the keyhole of the lock cylinder body 14. The lock cylinder body 14 is fixedly installed in the middle of the fuel tank cap lock body 1. One end of the lock cylinder body 14 has a keyhole, and the other end has a control shaft. A locking tongue body 2 is slidably connected to one end of the lock cylinder body 14, and the locking tongue body 2 is used to engage with the inner wall of the fuel tank opening. The inner wall of the fuel tank opening is provided with a snap-fit ​​structure. The bottom of the latch body 2 is provided with an automatic unlocking mechanism. The side of the latch body 2 is provided with a slot 22. The inner wall of the slot 22 is movably connected to one end of the control shaft of the lock cylinder body 14. The control shaft is an eccentric shaft. When it rotates, it can drive the latch body 2 to slide horizontally, thereby unlocking or locking. One end of the latch body 2 is an inclined surface. The other end of the latch body 2 has an installation groove 21. The inner wall of the installation groove 21 is movably connected to the latch spring 17. When the latch body 2 is squeezed, the latch spring 17 has a compression elastic force. The elastic force can make the latch body 2 slide automatically. One end of the latch spring 17 is snapped with a rear cover 18. One end of the rear cover 18 is threadedly fastened to the fuel tank cap lock body 1 by screws.

[0017] The automatic unlocking mechanism includes a storage sleeve 25, which is fixedly embedded in the bottom of the bolt body 2. One end of the storage sleeve 25 is provided with a storage groove 26. The inner wall of the storage groove 26 is fixedly connected to a first electric telescopic rod 27 and a second electric telescopic rod 28. The first electric telescopic rod 27 and the second electric telescopic rod 28 are provided with wireless controllers. The storage groove 26 of the storage sleeve 25 can store the telescopic block 24 and the stop block 23. One end of the first electric telescopic rod 27 is provided with a movable rod, the surface of which is slidably connected to the inner wall of the bolt body 2. One end of the second electric telescopic rod 28 is fixedly connected to the telescopic block 24, the surface of which is provided with the stop block 23. After the first electric telescopic rod 27 extends and abuts against the inner wall of the rear cover 18, it can control the bolt body 2 to slide.

[0018] A number of sealing springs 11 are inserted into one end of the fuel tank cap lock body 1. The sealing springs 11 are distributed in a ring at equal intervals. One end of the sealing spring 11 is snapped with a compression ring 12. The sealing spring 11 generates a compressive elastic force after being squeezed by the compression ring 12. The elastic force can improve the sealing effect. One surface of the compression ring 12 is fixedly connected with T-shaped clips distributed in a ring at equal intervals. The surface of the clips is snapped with one end of the sealing spring 11. The number of clips is the same as the number of sealing springs 11, which facilitates the installation and replacement of sealing springs 11.

[0019] A sealing gasket 13 is fixedly bonded to the surface of the extrusion ring 12. The sealing gasket 13 is made of corrosion-resistant and oil-resistant rubber. The sealing gasket 13 is extruded with the oil tank opening, which has the function of sealing the connection gap. An adhesive layer is provided on the surface of the sealing gasket 13, which is bonded to the surface of the extrusion ring 12 to facilitate the installation and fixation of the sealing gasket 13.

[0020] The working principle of this device is as follows: During use, the key controls the lock cylinder body 14, which in turn controls the bolt body 2 to extend or retract from the rear cover 18. When the bolt body 2 extends from the rear cover 18, the oil tank cover is locked. When the bolt body 2 retracts from the rear cover 18, the oil tank cover is opened. If the lock cylinder body 14 is damaged or the key is lost, the second electric telescopic rod 28 can be controlled to retract, thereby causing the stop block 23 and telescopic block 24 to retract into the storage slot 26. At this time, the bolt body 2 will not be obstructed by the lock cylinder body 14 when it slides horizontally into the rear cover 18. Then, one end of the first electric telescopic rod 27 is extended, causing one end of the movable rod to contact the inner wall of the oil tank opening, thereby causing the bolt body 2 to retract into the rear cover. The latch body 2 retracts inward, disengaging from the inner wall of the fuel tank opening. Then, the fuel tank cap is opened, causing one end of the latch body 2 to misalign with the fuel tank opening. The first electric telescopic rod 27 then retracts, fully opening the fuel tank cap. The latch body 2 can be horizontally moved by the lock cylinder body 14 and the latch spring 17 to lock and open the fuel tank cap. If the lock cylinder body 14 is damaged or the key is lost, the second electric telescopic rod 28 can control the stop block 23 and the telescopic block 24 to retract. The first electric telescopic rod 27 extends and presses against the inner wall of the fuel tank opening, causing the latch body 2 to retract and open the fuel tank cap. This does not affect the opening and closing of the fuel tank cap, improving ease of use.
