[0001] The present invention belongs to the technical field of automobile accessories, and in particular relates to a charging port cover for a new energy vehicle that can be opened at a large angle and an opening method thereof. Background Art

[0002] With the continuous development of new energy vehicles, many parts of traditional fuel vehicles have been optimized and upgraded to cater to the experience of end consumers. Among them, the automatic charging port cover is an upgrade and evolution based on the traditional fuel tank cover of fuel vehicles. The automatic charging port cover can be opened in a variety of ways, such as button opening, central control screen opening, mobile phone APP opening, charging gun approaching opening, etc., giving users a better sensory experience.

[0003] However, existing charging port covers on the market have an opening angle between 90° and 95°. Furthermore, on some models, when the small door is open, the charging station is not fully visible to the user, causing user complaints. Even without other mechanisms, increasing the opening angle further would result in a gap between the edge of the charging port cover and the body sheet metal that is too small, or even causing interference. Due to space and surrounding structural limitations, existing charging port covers cannot be opened at a wide angle. Summary of the Invention

[0004] In order to address the deficiencies of the prior art, the present invention provides a charging port cover for a new energy vehicle that can be opened at a large angle and an opening method thereof.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A charging port cover for new energy vehicles that can be opened at a large angle includes a shell and a charging port cover connected to one end of the shell and flipped along the shell. The shell and the charging port cover are connected by a hinge arm assembly. A accommodating cavity is provided at one end of the shell, and one end surface of the accommodating cavity is arranged in an arc shape. A driving mechanism for driving the hinge arm assembly to rotate is provided on one side of the accommodating cavity. The driving mechanism drives the hinge arm assembly to move in the accommodating cavity to drive the charging port cover to open or close.

[0007] Preferably, the hinge arm assembly includes a gooseneck hinge arm and a two-stage stroke push rod arranged on the hinge arm, and the upper end of the two-stage stroke push rod is connected to the charging port cover through a two-stage stroke connecting rod.

[0008] Preferably, a guide protrusion is provided in the middle of the hinge arm, and a guide hole is provided in the middle of the second-stage stroke push rod. The second-stage stroke push rod is placed on the guide protrusion through the guide hole, and the upper end of the second-stage stroke push rod passes through the upper surface of the hinge arm downward and is connected to the outer cover of the charging port through the second-stage stroke connecting rod.

[0009] Preferably, the lower end of the two-stage stroke push rod is downwardly penetrated from the upper surface of the hinge arm and protrudes to be placed on the inner side of the hinge arm, and the lower end of the two-stage stroke push rod is arranged at the gooseneck corner of the hinge arm.

[0010] Preferably, the upper end of the hinge arm is connected to the outer cover of the charging port through an axle pin, and a coil spring is also provided on one side of the axle pin.

[0011] Preferably, the lower end of the hinge arm is connected to the driving mechanism via a second axle pin.

[0012] Preferably, the hinge arm assembly further comprises a hinge arm cover covering the hinge arm, and the hinge arm cover is provided with a protruding column for being embedded in the guide protrusion.

[0013] Preferably, the hinge arm cover and the hinge arm are connected by screws.

[0020] The present invention discloses a charging port cover for new energy vehicles that can be opened at a large angle. Figure 1-Figure 3 As shown, it includes a shell 1 and a charging port cover 2 connected to one end of the shell 1 and flipped along the shell 1. The shell 1 and the charging port cover 2 are connected by a hinge arm assembly.

[0021] One end of the housing 1 is provided with a housing cavity 12. The upper end surface of the housing cavity 12 is linear, and the lower end surface is curved. A drive mechanism 3 is provided on one side of the housing cavity 12 to drive the hinge arm assembly to rotate. The drive mechanism 3 drives the hinge arm assembly within the housing cavity to open or close the charging port cover. The drive mechanism 3 is a motor.

[0022] The hinge arm assembly includes a gooseneck hinge arm 4 and a two-stage stroke push rod 6 provided on the hinge arm 4. The upper end of the two-stage stroke push rod 4 is connected to the charging port outer cover 2 through a two-stage stroke connecting rod 43. The upper end surface of the hinge arm 4 is also covered with the hinge arm cover 7. The hinge arm cover 7 is screwed to the upper and lower ends of the hinge arm 4 through screw holes 72. Specifically, the hinge arm 4 is a gooseneck structure consisting of a straight section and an arc-shaped section provided above the straight section and connected to the straight section. The hinge arm 4 is hollow, and a guide protrusion 5 is protruded from the middle thereof. A gap 41 is formed between the guide protrusion 5 and the circumference. Correspondingly, a protrusion 71 for being embedded in the guide protrusion is protruded on the hinge arm cover 7.

[0023] The upper end of the hinge arm 4 is connected to the charging port cover 2 via an axle pin 42, with a coil spring attached to one side of the axle pin 42. The lower end of the hinge arm 4 is connected to the drive mechanism 3 via a second axle pin 44, which is positioned within the axial hole 11 at the upper end of the accommodating chamber 12.

[0024] A guide hole 62 is provided in the middle of the second-stage push rod 6. The second-stage push rod 6 is inserted into the guide protrusion 5 through this guide hole 62. The edge of the guide hole 62 is positioned within the gap 41, and the entire second-stage push rod 6 is embedded in the hinge arm 4. The upper end 63 and the lower end 61 of the second-stage push rod 6 are each positioned at an angle to the middle portion. Both the upper end 63 and the lower end 61 extend toward the lower surface of the hinge arm 4, with the angle between the lower end 61 and the middle portion being smaller than the angle between the upper end 63 and the middle portion. In this embodiment, the upper surface of the hinge arm 4 serves as the upper display surface when the hinge arm is opened upward.

[0025] The upper end 63 of the second-stage push rod 6 extends downward from the upper surface of the hinge arm 4, and the hinge arm 4 is connected to the charging port cover 2 via the second-stage connecting rod 43. The second-stage connecting rod 43 is pivotally connected to the upper end of the second-stage push rod 6. The other end of the second-stage connecting rod 43 is connected to the edge of the charging port cover 2. The connection between the hinge arm 4 and the charging port cover 2 is located on the inner side of the second-stage connecting rod 43.

[0026] The lower end 61 of the two-stage stroke push rod 6 is downwardly penetrated from the upper surface of the hinge arm 4 and protrudes onto the inner side of the hinge arm 4. The lower end of the two-stage stroke push rod 6 is arranged at the gooseneck corner of the hinge arm 4 and above the straight section.

[0027] The present invention also discloses a method for opening the charging port cover, which specifically includes the following steps:

[0028] The driving mechanism 3 works, driving the hinge arm 4 to rotate through the second axle pin 44, thereby driving the charging port outer cover 2 to open. When the charging port outer cover 2 is opened to 90 degrees with the bottom cover of the shell 1, the protruding lower end 61 of the second-stage stroke push rod 6 is blocked by the shell surface 13, thereby forcing the second-stage stroke push rod 6 to move downward along the guide protrusion 41, driving the second-stage stroke connecting rod 43 connected to it at the upper end to rotate, overcoming the force applied by the coil spring to the charging port outer cover, so that the charging port outer cover 2 continues to rotate along the axle pin 42 until the straight section of the hinge arm 4 abuts against the shell surface 13, reaching the set position of the second stage opening.
