Hinge four-bar type charging port and oil filling port assembly

Abstract

The invention discloses a hinge four-bar type charging port and oil filling port assembly which comprises a port pipe assembly, an actuator assembly and a wire harness assembly. The mouth pipe assembly comprises a mouth pipe body and a frame. More than one rocking bar is oppositely arranged in the mouth pipe body; a rocker driving shaft is inserted into the side surface of the mouth pipe body; the upper ends of the rockers are connected with the frame, and the lower ends are connected with rocker driving shafts; the actuator assembly is connected with the port pipe body and drives the rocker driving shaft. A gooseneck rotating shaft is omitted, the Y-direction space of the mouth pipe assembly is reduced, and arrangement of other parts of a vehicle is facilitated; after opening, the covering cap shielding area is small, the user operation view is wide, and refueling and charging are convenient; more than one rocker is driven by the rocker driving shaft, so that the upper cover is opened, and more choices and better experience are brought to the use of a user.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hinged four-bar type charging port and a fuel filler port assembly. Background technique [0002] At present, the opening method of the vehicle cover is simple in structure, less in types, and less optional for users; such as Figure 1 and Figure II as well as Figure 8 shown; [0003] 1. The existing gooseneck cover assembly requires a relatively large radius of the rotating shaft. During the opening process, there is a certain safety distance D1 from the upper R of the body sheet metal, and a sufficient safety distance D2 from the body sheet metal after it is fully opened. The radius of the rotating shaft It needs to be arranged inside the assembly, which occupies a large space in the Y direction, which restricts the arrangement of other parts of the vehicle; when the traditional flap is opened, it blocks the view and causes refueling and charging interference; [000...

AI Technical Summary

Problems solved by technology

[0003] 1. The existing gooseneck cover assembly requires a relatively large radius of the rotating shaft. During the opening process, there is a certain safe distance D1 from the upper R of the body sheet metal, and there is a sufficient safe distance D2 from the body sheet metal after it is fully opened. The radius of the rotating shaft It needs to be arranged inside the assembly, occupying a large space in the Y direction, which restricts the arrangement of other parts of the vehicle; when the traditional cover is opened, it blocks the view and causes interference with refueling and charging;

[0004] 2. The sealing performance of the cover assembly is low, the surface difference is not easy to control, and there is abnormal sound when the cover is closed;

[0005] 3. The traditional actuator adopts flat gear transmission, which has many transmission stages and takes up a lot of space; the design structure of the actuator is not compact enough, the sealing effect is poor, and the sealing level is low; the traditional clutch structure uses end-face contact to generate friction, and the friction per unit length The force is the clutch torque; specifically, the spring applies axial pressure to the friction surface. The product of the axial pressure and the friction coefficient of the material is the friction force. The torque per unit length of the friction force in the circumferential direction is the clutch torque. The friction force and the friction coefficient 1. The spring pressure is proportional to the friction coefficient of ordinary materials. To increase the clutch torque, it is necessary to increase the diameter of the spring or increase the compression length of the spring. The structure of the traditional clutch is relatively complicated and the cost is high;

[0006] 4. The traditional switch is a mechanical limit switch, which needs to be pressed to deform the cover, and then trigger the limit switch

When the pressing area changes, the pressing force changes or the deformation is uneven, the pressing area cannot touch the travel switch, and the pressing area is not in place, and the cover cannot be opened; long-term pressing will cause the cover to deform, and the skin coating of the pressing area will fall off. Causes a change in the level difference and damages the appearance
