Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide a fuel tank cap for an automobile. By utilizing the gap between the inner plate and the outer plate of the fuel tank cap to design a fuel tank cap placement structure, the fuel tank cap can realize the storage function and has a simple structure and will not increase the volume of the automobile fuel tank cap, thereby improving the wide application of the fuel tank cap.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] See also Figure 1The present embodiment provides a fuel filler cap for an automobile, comprising a fuel filler cap outer plate 1, a fuel filler cap inner plate 2 and a fuel filler cap box 3, wherein the fuel filler cap outer plate 1 is connected to the fuel filler cap inner plate 2, one end of the fuel filler cap inner plate 2 is connected to the fuel filler cap box 3, and the other end of the fuel filler cap inner plate 2 is connected to the fuel filler cap box 3 via a locking mechanism 9;

[0038] Considering that when refueling a car, there is no place to place the fuel tank cap after opening the fuel tank cap, and it can only be hung, another structure for placing the fuel tank cap is provided. That is, a first slide groove 4 is provided on the side of the fuel filler cap outer panel 1 close to the fuel filler box 3; a fuel tank cap support plate 5 is provided between the fuel filler cap outer panel 1 and the fuel filler cap inner panel 2, and the fuel tank cap support plate 5 includes a fixed portion 51 and a rotating portion 52, and the fixed portion 51 and the rotating portion 52 are rotationally connected, and the rotational connection can be achieved by providing a groove on the side of the fixed portion 51 and providing a protrusion 511 matching the groove at a position corresponding to the rotating portion 52. A protrusion 511 is provided at one end of the fixed portion 51, and the protrusion 511 is placed in the first slide groove 4 and slides back and forth in the first slide groove 4;

[0039] The rotating part 52 is provided with a storage hole 521, and the diameter of the storage hole 521 is larger than the diameter of the threaded part of the fuel tank cover and smaller than the diameter of the limiting part of the fuel tank cover;

[0040] When the protrusion 511 slides to one end of the first slide groove 4, the fuel tank cover supporting plate 5 is located between the fuel filler cover outer plate 1 and the fuel filler cover inner plate 2;

[0041] When the protrusion 511 slides to the other end of the first slide groove 4, the fuel tank cap support plate 5 slides out from between the fuel tank cap outer plate 1 and the fuel tank cap inner plate 2, and when the rotating part 52 is perpendicular to the fixing part 51, the fuel tank cap threaded part is placed in the storage hole 521.

[0042] When the fuel tank cap needs to be placed in the above-mentioned storage structure, it is only necessary to slide the fuel tank cap support sheet 5 out from between the fuel tank cap outer plate 1 and the fuel tank cap inner plate 2, and rotate the rotating part 52 of the fuel tank cap support sheet 5 to make the rotating part 52 perpendicular to the fixed part 51, so that the fuel tank cap can be vertically placed in the storage hole 521; when it is not needed, it is only necessary to rotate the rotating part 52 again, and when the rotating part 52 and the fixed part 51 are in the same plane, push the fuel tank cap support sheet 5 to slide between the fuel tank cap outer plate 1 and the fuel tank cap inner plate 2. The above-mentioned storage structure is simple in structure, does not increase the volume of the fuel tank cap of the car, and is highly practical.

[0043] Considering that when the fuel filler cap is calibrated, twisting the fuel filler cap inner plate 2 will generate a certain force on the fuel filler cap outer plate 1, which may easily cause deformation of the fuel filler cap outer plate 1, thereby affecting the appearance of the entire vehicle body. To address this problem, it is generally required that there is a certain gap between the fuel filler cap outer plate 1 and the fuel filler cap inner plate 2. For this purpose, this embodiment provides a connection structure between the fuel filler cap outer plate 1 and the fuel filler cap inner plate 2.

[0044] The fuel filler cap outer plate 1 is also provided with a plurality of first protrusions 6 on one side close to the fuel filler cap box 3; the fuel filler cap inner plate 2 is provided with a plurality of extension pieces 7 corresponding to the first protrusions 6 one by one around the periphery, and each extension piece 7 is welded to the corresponding protrusion. For the sake of aesthetics and force balance, it is required that the plurality of extension pieces 7 are provided at equal intervals on the edge of the fuel filler cap inner plate 2.

[0045] In addition, the first slide groove 4 may be arranged in a region surrounded by a plurality of the first protrusions 6 .

[0046] In order to prevent the extension piece 7 from being deformed when being welded to the first protrusion 6 , a process hole may be provided on the extension piece 7 ; the diameter of the protrusion increases from the top to the bottom; and the top of the protrusion is embedded in the process hole on the extension piece 7 .

[0047] Considering that the existing fuel filler cap inner plate 2 and the fuel filler box 3 are generally connected by a hinge arm, when the fuel filler cap is opened, the fuel filler cap outer plate 1 and the fuel filler cap inner plate 2 can only flip around the hinge arm as the center, and this embodiment provides a structure that can realize the fuel filler cap outer plate 1 and the fuel filler cap inner plate 2 sliding open in parallel. The fuel filler cap inner plate 2 is connected to the fuel filler box 3 through a sliding mechanism 8; the sliding mechanism 8 includes a telescopic rod 81 and a second slide groove 82; the second slide groove 82 is provided on the surface of the fuel filler cap inner plate 2 close to the fuel filler box, one end of the telescopic rod 81 is rotatably connected to the fuel filler box 3 (the telescopic rod 81 swings relative to the fuel filler box 3), and the other end of the telescopic rod 81 is provided with a block 83, and the block 83 is placed in the second slide groove 82 and slides back and forth in the second slide groove 82;

[0048] The maximum extension length of the telescopic rod 81 is greater than the distance from the fuel filler opening to the connection point between the telescopic rod 81 and the fuel filler opening box 3 .

[0049] When the block 83 slides to one end of the second slide groove 82, the fuel filler cap inner plate 2 covers the fuel filler port;

[0050] When the block 83 gradually slides to the other end along the second slide groove 82, the inner plate 2 of the fuel filler cap gradually translates relative to the fuel filler port. After the translation, the portion of the fuel filler port not covered by the inner plate 2 of the fuel filler cap can at least pass through the fuel gun of the gas station.

[0051] As an implementable method, this embodiment provides a locking mechanism 9 that can be pressed to open and then pressed to close. Figure 2 As shown, the locking mechanism 9 includes a limiting hole 91 provided on the fuel filler cap inner plate 2, a limiting block 92 matched with the limiting hole 91, and a driving mechanism 93 for engaging or separating the limiting block 92 from the limiting hole 91;

[0052] The driving mechanism 93 includes a first guide tube 931, a second guide tube 932, a guide column 933 and a bottom plate 934;

[0053] One end of the first conduit 931 is fixedly connected to the bottom plate 934, and the inner surface of the first conduit 931 is provided with a spiral groove (not shown in the figure);

[0054] The guide post 933 is placed in the first conduit 931 and one end of the guide post 933 is fixedly connected to the bottom plate 934;

[0055] One end of the second conduit 932 is sleeved on the guide post 933 , and the other end of the second conduit 932 is connected to the limit block 92 . A second protrusion 935 is provided on the outer surface of the second conduit 932 , and the second protrusion 935 is placed in the spiral groove.

[0056] The other end of the first conduit 931 is provided with a baffle (not shown in the figure); the second conduit 932 is provided with a convex edge 936, and the convex edge 936 is provided between the limit block 92 and the second protrusion 935;

[0057] When the second protrusion 935 moves upward to a preset position along the spiral groove, the baffle clamps the convex edge 936;

[0058] When the baffle clamps the convex edge 936 , the limiting hole 91 blocks the limiting block 92 from passing through.

[0059] A compression spring is provided between the second guide tube 932 and the bottom plate 934 , and the compression spring is sleeved on the guide post 933 .

[0060] When the fuel filler cap is closed, the fuel filler cap is pressed, the stopper 92 is pressed, and the second protrusion 935 on the second conduit 932 slides downward along the spiral groove on the inner surface of the first conduit 931. During the sliding process, the second conduit 932 rotates along the guide column 933, thereby driving the stopper 92 to rotate. When the stopper 92 is rotated to be completely placed in the limit hole 91, the fuel filler cap is opened, and during the rotation process, the second conduit 932 generates pressure on the compression spring, and under the action of the pressure, the compression spring causes the fuel filler cap to pop open. When the fuel filler cap needs to be closed, the fuel filler cap needs to be pressed, the stopper 92 is pressed, and the second protrusion 935 on the second conduit 932 slides downward along the spiral groove on the inner surface of the first conduit 931, thereby driving the stopper 92 to rotate, and the limit hole 91 can prevent the stopper 92 from passing.

[0061] Considering that the fuel filler cap will be impacted when closing it, a buffer mechanism is provided for this purpose, that is, a plurality of buffer blocks 11 are provided on the surface of the fuel filler cap inner plate 2 close to the fuel box, and a plurality of buffer bayonet holes 12 are provided on the box opening of the fuel box, and the buffer blocks 11 correspond to the buffer bayonet holes 12 one by one, and the buffer blocks 11 and the buffer bayonet holes 12 are interference fit. The above structure can buffer the force of closing the fuel filler cap, thereby effectively buffering the impact during the fuel filler cap closing process. In addition, the interference fit between the buffer blocks 11 and the buffer bayonet holes 12 can make the fuel filler cap inner plate 2 close to the fuel box and tightly connected to avoid vibration.

[0062] In this embodiment, a fuel tank cap placement structure is designed by utilizing the gap between the fuel filler cap inner plate 2 and the outer plate, which can realize the storage function, has a simple structure and does not increase the volume of the fuel filler cap of the automobile, thereby improving the wide application of the fuel filler cap. In addition, a sliding mechanism 8 and a locking mechanism 9 are provided between the fuel filler cap inner plate 2 and the fuel filler box 3, further improving the wide application of the fuel filler cap.
