Problems solved by technology

However, the technical solutions of the above two product patents all use the snap connection between the electric telescopic rod and the locking port of the inner panel to realize the locking of the fuel filler cap, and the motorization is only realized during the unlocking process of the fuel filler cap, while the fuel filler cap The opening, closing and locking of the fuel tank require the operator to operate manually outside the vehicle, which cannot realize the complete electric automation of the whole process, and has no error-proof function, and cannot realize the automatic closing and locking function when the fuel filler cap is not closed during driving.

Embodiment 1

[0036]This embodiment is an electrically controlled opening and closing fuel filler cap, refer to figure 1 , figure 2 , Figure 4 — Figure 7 , which includes a fuel filler cap pipe 1, a hinge arm 2, a cover plate 3, a fuel filler cap body 4, and an electric opening and closing device for opening and closing the fuel filler cap body 4 controlled by the vehicle ECU. The working end of the device is linked with the fuel filler cap body 4 . Specifically:

[0037] The electric opening and closing device includes a driven rotating member that is integrally connected with the fuel filler cap body 4 and can rotate coaxially and synchronously. fuel filler cap switch 6. Fuel filler cap switch 6 corresponds to the corresponding position ahead of the driver's seat on the car body, such as instrument panel panel, left front door guard plate, and can also be fixed in other places that are convenient for the driver to operate.

[0038] The output shaft of the motor 5 is fixedly conne...

Embodiment 2

[0062] This embodiment is an electrically controlled opening and closing fuel filler cap, which differs from Embodiment 1 in that:

[0063] The cross-sectional structure of the side where the closing action limiting device 7 is close to the card arm 18 is a "7" shape with a right angle at the corner (used to replace the one in the closing action limiting device 7 and the card arm 18 that is close to the locking arm 18 in Embodiment 1). "]"-shaped limit groove on one side).

[0064] The structure of other parts of this embodiment is exactly the same as that of Embodiment 1.

Embodiment 3

[0066] This embodiment is an electrically controlled opening and closing fuel filler cap, which differs from Embodiment 1 in that:

[0067] The closing action limiting device 7 is knife-shaped, that is, it includes an upper toothed strip part and a lower single-leg part. The arc-shaped edge of the chainring 10 can be located below the strip-shaped part and the radius is smaller than the radius of the single-leg. Rotate in the area. (That is: the chainring 10 no longer has the arc-shaped extension end 13; the single leg replaces the two legs of embodiment 1)

[0068] The structure of other parts of this embodiment is exactly the same as that of Embodiment 1.

Abstract

The invention discloses an electric control opening and closing fuel filler cap, which comprises a fuel filler cap mouth tube, a fuel filler cap body, and an electric opening and closing device for opening and closing the fuel filler cap body controlled by a vehicle ECU. The working end of the opening and closing device is linked with the fuel filler cap body. The invention realizes the automatic operation of unlocking, opening, closing and locking of the fuel filler cap body driven by the electric opening and closing device under the control of the vehicle ECU under the drive of the power supply, fully improves the automation of the fuel filler cap operation, and is further provided with The anti-mistake switch can realize the automatic closing and locking of the fuel filler cap when the fuel filler cap is not closed due to forgetting to close it or other circumstances. The invention is applicable to various vehicles, is connected with ECU, and realizes the automatic control of unlocking, opening, closing and locking of the fuel filler cap.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to a fuel filler cap for a vehicle, in particular to a fuel filler cap whose opening and closing is electrically controlled. Background technique [0002] Existing vehicle fuel filler caps are unlocked by opening pull wires or motors, and then manually lifted by the operator to complete the opening process. With this type of fuel filler cap, except for the unlocking action of the fuel filler cap, the opening process and closing process are all manually completed by the operator, and the degree of automation is low. If the operator forgets to close the fuel filler cap or other circumstances, the fuel filler cap will not be closed. At this time, the fuel filler cap is always in the open state, which does not protect the oil pipe and prevent theft. [0003] The Chinese patent database discloses technical solutions for controlling the opening and closing of the fuel filler cap through various ...
