DETAILED DESCRIPTION

[0028] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] See also Figure 1-5 The utility model provides an electronically controlled fuel tank cover assembly, comprising a fuel tank body 1, wherein a fuel filling port 10 is convexly provided on one side of the fuel tank body 1;

[0030] A fuel tank cap 2, wherein the fuel tank cap 2 is disposed on the fuel filling port 10, and the fuel tank cap 2 completely covers the fuel filling port 10;

[0031] The electrically controlled locking device 3 includes a lock housing 30 disposed on the fuel filler port 10, a driving device 31 disposed in an internal cavity of the lock housing 30, a locking device 32 driven by the driving device 31, and a control device 33 for controlling the start and stop of the driving device 31, wherein the locking device 32 is used to lock the fuel tank cover 2.

[0032] In the above structure, when refueling is needed, the control device controls the driving device to start, and the driving device drives the locking device to unlock. When refueling is completed, the control device controls the driving device to rotate in the opposite direction, thereby driving the locking device to lock. The use of an electronically controlled locking device replaces the driver's use of a key to unlock or lock the fuel tank cap when refueling is needed, which can facilitate the driver's operation when refueling.

[0033] Specifically, a wire 100 for supplying power to the driving device 31 is provided on one side of the electric-controlled locking device 3, and a receiving groove 101 for accommodating the wire 100 is recessed on the fuel tank body 1. The receiving groove for accommodating the wire on the fuel tank body can not only store the wire for protection, but also increase the aesthetics and make the visual effect not abrupt.

[0034] Specifically, the fuel tank cap 2 includes a cover body 20 and a fixing portion 22 fixedly arranged at the lower end of the fuel tank cap 2, the fixing portion 22 is convexly provided with a thread 220, and the inner wall of the fuel filling port 10 is concavely provided with a thread groove 11 used in conjunction with the thread 220. The use of threads and thread grooves as a fixing method for fixing the fuel tank cap to the fuel filling port has the advantages of multiple uses, simple structure, and stable connection.

[0035] Specifically, an annular tooth block 21 is fixedly provided on the fuel tank cover 2, and the locking device 32 includes a moving block 320 used in conjunction with the driving device 31 and a ratchet portion 321 arranged on one side of the moving block 320 and meshing with the annular tooth block 21. The meshing of the ratchet and the annular tooth block can ensure that the fuel tank cover is tightened in one direction in the locked state. When someone wants to unscrew the fuel tank cover in the locked state, the teeth of the annular tooth block are resisted by the ratchet portion so that the cover is locked and cannot be unscrewed.

[0036] Specifically, a sealing ring 221 is provided around the bottom end of the fixing portion 22, and the sealing ring can ensure that the oil in the oil tank will not leak out from the filling port.

[0037] Specifically, the cover body 20 is provided with a pattern, and the pattern on the cover body can increase the friction force when the fuel tank cap is twisted, thereby achieving a labor-saving effect.

[0038] Specifically, a limiting groove 300 for accommodating the driving device 31 is convexly provided in the lock housing 30. The limiting groove can ensure that the driving device will not be forced to change its position during operation, thereby failing to properly drive the locking device to operate.

[0039] Specifically, the control device 33 is a PCB board, and the PCB board can delay the automatic reset of the locking device 32. Using the PCB board as the control device can cancel the internal lead optimization process, thereby eliminating the undesirable phenomenon of lead leakage. The delayed automatic reset can reduce the steps of re-locking after the driver unlocks, and at the same time ensure that when the driver forgets to lock, the locking device is still in the state of locking the fuel tank cap through the delayed locking function.

[0040] Specifically, the locking device 32 is provided with a cam 322, and the moving block 320 is recessed with a cam groove 323 used in conjunction with the cam 322. The cooperation between the cam and the cam groove allows the driving device to drive the rotational motion of the locking device to be converted into reciprocating motion, thereby ensuring the linear telescopic motion of the moving block.

[0041] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
