[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figure 1-8 The utility model provides a technical solution: a vehicle refueling door control device, comprising:

[0035] like Figure 1-3 The guide sleeve 1 shown has a plurality of first protrusions 11 fixedly connected to the outside of the guide sleeve 1, a first stop ring 13 fixedly sleeved inside the guide sleeve 1, and a slider 12 fixedly connected to the inner wall of the first stop ring 13. Among them, a plurality of first shallow guide grooves 1301 and first deep guide grooves 1302 are axially opened at one end of the first stop ring 13 close to the spiral shaft 3, the first shallow guide grooves 1301 and the first deep guide grooves 1302 are arranged at intervals, and adjacent first shallow guide grooves 1301 and first deep guide grooves 1302 are connected by a curved transition.

[0036] like Figure 1 and Figure 4-6 The upper cover assembly 2 shown includes an upper cover 21, a second limiting ring 22, a stepped shaft 23 and a first buckle 24 in an integrated structure. The upper cover 21 is clamped on one end of the guide sleeve 1 close to the first limiting ring 13. The first buckle 24 is fixed on the outside of the upper cover 21. The first buckle 24 is clamped with the first protrusion 11. The second limiting ring 22 and the stepped shaft 23 are fixed in the middle of the upper cover 21. The stepped shaft 23 is located on the inside of the second limiting ring 22. The reset spring 5 is sleeved on the stepped shaft 23. Among them, the free end of the second limiting ring 22 is provided with a plurality of second shallow guide grooves 2201 and second deep guide grooves 2202 along the axial direction. The second shallow guide grooves 2201 and the second deep guide grooves 2202 are arranged at intervals, and adjacent second shallow guide grooves 2201 and second deep guide grooves 2202 are connected by a curved transition.

[0037] like Figure 1 and Figure 7The spiral shaft 3 shown has a spiral groove 301 that is slidably matched with the slider 12. One end of the spiral shaft 3 is slidably sleeved into the first limit ring 13 from the other end of the guide sleeve 1. A hollow groove is provided in the spiral shaft 3, and the stepped shaft 23 extends into the hollow groove. One end of the spiral shaft 3 is fixedly connected with a plurality of second buckles 32, and the other end of the spiral shaft 3 is fixedly connected with a limit rod 31. When the spiral shaft 3 is pressed, due to the structural restrictions of the spiral groove 301 and the slider 12, the spiral shaft 3 rotates 90° each time. The cover plate has a connection structure that cooperates with the limit rod 31. The cover plate is pressed to squeeze the spiral shaft 3 while moving away from the guide sleeve 1 and rotating 90°. The limit rod 31 is separated from the connection structure, and the cover plate is opened. After closing the cover plate, the cover plate is pressed again to squeeze the spiral shaft 3 and rotate 90° again. The limit rod 31 is connected to the connection structure to close the cover plate.

[0038] like Figure 1 and Figure 8 The rotor 4 shown is sleeved on the second buckle 32, and a plurality of second protrusions 41 are fixedly connected to the outer side of the rotor 4, and the second protrusions 41 are arranged between the opposite surfaces of the first limiting ring 13 and the second limiting ring 22. In the two sets of limiting rings, the axial opening positions of the deep guide groove and the shallow guide groove are the same, and the second protrusion 41 moves along the curved surface to achieve its cooperation with the first shallow guide groove 1301 and the second shallow guide groove 2201, or with the first deep guide groove 1302 and the second deep guide groove 2202. The rotor 4 moves synchronously with the screw shaft 3. When the screw shaft 3 is pressed and rotated 90° to open the cover, the second protrusion 41 on the rotor 4 moves along the curved surface from between the two groups of shallow guide grooves to between the two groups of deep guide grooves, and the second protrusion 41 loses axial restriction. Under the elastic force of the reset spring 5, it moves away from the guide sleeve 1 together with the screw shaft 3, and the second protrusion 41 enters the first shallow guide groove 1301, and the limit rod 31 disengages from the cover. Afterwards, the screw shaft 3 is pressed and rotated 90° again to close the cover. When the second protrusion 41 on the rotor 4 moves along the curved surface from between the two groups of shallow guide grooves to between the two groups of deep guide grooves, the second protrusion 41 is restricted in the axial direction and enters the guide sleeve 1 together with the screw shaft 3, and the limit rod 31 locks the cover.

[0039] The cover plate is opened by sliding the rotor 4 on the deep and shallow guide grooves and the transitional curved surface between the guide grooves. The two sets of limit rings and the deep and shallow guide groove structures thereon make the gap surface difference of the cover plate easy to control and the pressing force value stable.

[0040] Working principle: When in use, when the spiral shaft 3 is pressed, due to the structural restrictions of the spiral groove 301 and the slider 12, the spiral shaft 3 rotates 90° each time, and the cover plate has a connection structure that cooperates with the limit rod 31. The rotor 4 moves synchronously with the spiral shaft 3. When the spiral shaft 3 is pressed and rotated 90° to open the cover plate, the second protrusion 41 on the rotor 4 moves from between the two groups of shallow guide grooves to between the two groups of deep guide grooves along the curved surface. The second protrusion 41 loses its axial restriction. Under the elastic force of the reset spring 5, the rotor 4 moves away from the guide sleeve 1 together with the spiral shaft 3, and the second protrusion 41 enters the first shallow guide groove 1301. The limit rod 31 is separated from the cover plate, and the cover plate is opened;

[0041] Afterwards, the screw shaft 3 is pressed and rotated 90 degrees again to close the cover plate. The second protrusion 41 on the rotor 4 moves along the curved surface from between the two groups of shallow guide grooves to between the two groups of deep guide grooves. The second protrusion 41 is axially restricted and enters the guide sleeve 1 together with the screw shaft 3. The limit rod 31 locks the cover plate, and the cover plate is closed, so that the gap surface difference of the cover plate is easy to control and the pressing force value is stable.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
