As shown in fig. 5, specifically, one end of the horizontally extending section 19 of the lock lever 21 protrudes into the track groove and can move in the track groove relative to the slider 29 when the slider 29 moves up and down. As shown in fig. 3, 6 and 8, a first protrusion 57 is provided in the track groove. As shown in fig. 8, a lateral groove 92 is formed between the bottom surface of the first protrusion 57 and the inner wall of the track groove, and a vertical groove 90 is formed between the side surface of the first protrusion 57 and the inner wall of the track groove. That is, the first protrusion 57 divides the track groove into a vertical groove 90 extending in the up-down direction and a lateral groove 92 extending upward from the bottom of the vertical groove 90. The lateral slots 92 communicate with the vertical slots 90. The lower portion of the track groove is provided with a stopper 94 for limiting the lock lever 21. Specifically, a limiting portion 94 is provided on a bottom surface of the first protrusion 57, and the lock lever 21 can abut against the limiting portion 94 to limit the upward movement of the slider 29 when moving downward relative to the slider 29. The locking lever 21 has a first position and a second position, and when the locking lever 21 is in the first position, i.e. not pressed, as shown in fig. 5, one end of the locking lever 21 is located at the top of the vertical groove 90, and the locking tongue 25 is in the extended position and in the unlocking state (the locking tongue 25 no longer locks the fuel tank cap), and when the locking lever is in the second position, as shown in fig. 8, the locking tongue 25 is pressed against the limiting portion 94, and the locking tongue 25 is retracted and in the locking state (the locking tongue 25 locks the fuel tank cap).

As shown in fig. 3, 6 and 8, in one embodiment, the first protrusion 57 has a bottom surface and a side surface extending upward from the bottom surface, further, a first inclined surface 59 and a second inclined surface 61 extending downward are provided on the bottom surface of the first protrusion 57, a first bent portion 71 having an included angle greater than 0 degree and smaller than 180 degrees is formed between the first inclined surface 59 and the second inclined surface 61, and the first bent portion 71 forms a limiting portion 94. So that the locking rod 21 can abut against the first bent portion 71 when being positioned below the first bent portion 71, thereby restricting the slider 29 from moving upward. First inclined plane 59 and second inclined plane 61 have the guide effect to locking pole 21 to guarantee that locking pole 21 can slide from vertical groove 90 towards first kink 71, thereby make locking pole 21 can the joint under first kink 71. The inner wall of the track groove is provided with a third inclined surface 63 and a fourth inclined surface 65 which extend downwards, the third inclined surface 63 faces the first inclined surface 59, the fourth inclined surface 65 faces the second inclined surface 61, the third inclined surface 63 is parallel to the first inclined surface 59, and the fourth inclined surface 65 is parallel to the second inclined surface 61. The lateral groove 92 thus includes a first lateral groove 81 formed between the first and third

inclined surfaces

59, 63 and a second lateral groove 83 formed between the second and fourth

inclined surfaces

61, 65. Therefore, the locking rod can be clamped under the first bending portion 71 through the first lateral groove 81 between the first inclined surface 59 and the third inclined surface 63, and can be clamped under the first bending portion 71 through the second lateral groove 83 between the second inclined surface 61 and the fourth inclined surface 65. It is thus ensured that the locking lever 21 can be snapped under the first bent portion 71 during the downward movement relative to the slider 29. Further, the third inclined surface 63 and the fourth inclined surface 65 have a guiding function on the lock lever 21 to ensure that the lock lever 21 can slide from the first bent portion 71 into the vertical groove 90. That is, when unlocking, the lock tongue 25 is pressed, and the slider 29 moves upward, so that the lock lever 21 can move downward along the third inclined surface 63 or the fourth inclined surface 65 with respect to the slider 29, and thus enter the vertical groove 90. The inner wall of the track groove is provided with a first cambered surface 85 and a second cambered surface 87 which are positioned at the opposite sides of the first bulge 57, the first cambered surface 85 and the second cambered surface 87 both extend downwards from the upper part of the first bulge 57, and the first cambered surface 85 and the second cambered surface 87 are both bent outwards. The first arc surface 85 and the second arc surface 87 have a guiding function, and ensure that the locking rod 21 can move up and down along the vertical groove 90. The side of the first protrusion 27 includes a fifth slope 67 and a sixth slope 69 opposite to each other, the fifth slope 67 facing the first arc 85, and the sixth slope 69 facing the second arc 87. The vertical slots 90 include a first vertical slot 77 formed between the fifth sloped surface 67 and the first curved surface 85 and a second vertical slot 79 formed between the sixth sloped surface 69 and the second curved surface 87. The first vertical groove 77 is located outside the second track groove. The second vertical groove 79 is located outside the first track groove. Since the first and second arc surfaces 85 and 87 are provided on the side walls of the track groove, when the lock lever 21 moves downward from above the first projection 57 with respect to the slider 29, it can enter the first vertical groove 77 along the first arc surface 85 or enter the second vertical groove 79 along the second arc surface 87. When the lock lever 21 moves along the first vertical groove 77, it can enter the first lateral groove 81 through the first inclined surface 59 and stop at the first bent portion 71. When the lock lever 21 moves along the second vertical groove 79, it can enter the second lateral groove 83 through the second inclined surface 61 and stop at the first bent portion 71. Thereby ensuring that the lock lever 21 can move from the vertical groove 90 to the position of the first bent portion 71.

As shown in fig. 3, a second bent portion 73 is preferably formed between the third inclined surface 63 and the fourth inclined surface 65, and the second bent portion 73 is opposite to the first bent portion 71. So that when the locking lever 21 is in the first position, depressing the bolt 25 causes the locking lever 21 to move downwardly along the third ramp 63 relative to the slider 29 and into the first vertical slot 77. Or to move the locking lever 21 downwards along the fourth ramp 65 with respect to the slider 29, so as to enter the second vertical groove 79.

Then, latch tongue 25 is released, so that pushing rod 27 drives slider 29 to move downwards under the action of first spring 31, that is, locking rod 21 moves relative to slider 29 from first lateral groove 81 (or second lateral groove 83) into first vertical groove 77 (or second vertical groove 79) and moves upwards, and then moves to the top of first vertical groove 77 (or second vertical groove 79). In this process, the first rotary guide device 35 is provided on the side surface of the main body 23, the main body 23 rotates by the first rotary guide device 35, the latch 25 rotates in the process of moving upward, and the latch 25 does not lock the fuel tank cap any more and is unlocked. I.e. the locking bar 21 is moved from the second position to the first position. In the second position, if the electric unlocking key of the fuel tank lock is pressed by mistake, the sliding block 29 cannot move upwards because the locking rod 21 abuts against the first bending part 71, so that the problem that the fuel tank opening cover is automatically opened is avoided.

In the present embodiment, the first spring 31 is located on a side of the main body 23 facing away from the latch tongue 25. As shown in fig. 1 and 4, the first spring 31 is located above the latch tongue 25, and the first spring 31 is disposed in the main body 23.
