In this embodiment, preferably, the sleeve 422 is connected to the mobile platform 400, and the sliding rod 421 is connected to the transmission cable 500, but it can also be swapped and configured, which is not limited in the present invention.

Referring to FIG. 5, the driving assembly 600 is linked with the driving cable 500 and can pull the driving cable 500 to displace the moving platform 400. In this embodiment, the driving assembly may also include a pair of winding shafts 620a and 620b. The pair of winding shafts 620a and 620b are driven by a motor 610 and driven by a gear set 630 to rotate in the same direction. Each of the winding shafts 620a and 620b is wound in the opposite winding direction. Therefore, regardless of whether the motor 610 is rotating forward or reverse, one of the winding shafts 620a (or 620b) releases one end of the driving cable 500 while the other winding shaft 620b (or 620a) winds up the other end of the driving cable 500, thereby The telescopic actuating lever 420 is driven to translate between the pair of guide wheels 510. The aforementioned forward rotation and reverse rotation of the motor 610 define that the motor 610 has two opposite rotation directions, rather than referring to a specific rotation direction. The forward and reverse rotation of the motor 610 drives the door cover 220 to move toward the opening 201 along the channel 310 and closes the opening 201, or drives the door cover 220 to retract from the opening 201.

The electric-driven door cover 220 has the advantage that, even if the vehicle owner finds that the door cover 220 is not closed after entering the vehicle, the door cover 220 can still be operated in the vehicle without closing the door cover 220 manually.

The vehicle door cover opening and closing mechanism of the present invention pushes the mobile platform 400 by a telescopic actuating lever 420, and allows the mobile platform 400 to move perpendicular to the transmission cable 500. The simple linear transmission cable 500 can drive the dual-axis displacement of the mobile platform 400 .

In the vehicle door cover opening and closing mechanism of the present invention, each of the channel 310 and the other channel 310 are arranged overlappingly, so that the space occupied by the channel 310 can be compressed, which reduces the volume of the track assembly 300. The ramp 312 of at least one of the channels 310 is overlapped with the straight line segments 311 of the other channel 310 so that the straight line segments 311 are arranged on the same plane and are flattened to shorten the thickness of the track assembly 300. However, depending on the required space, the straight line segments 311 may be overlapped to shorten the length of the track assembly 300.

Furthermore, the vehicle door cover opening and closing mechanism of the present invention operates the door cover 220 to be opened and closed by the driving cable 500, so it can extend the distance between the motor 610 and the input connector 100 by configuring a longer driving cable 500, so that it can It is applied to the fuel filler port to avoid the introduction of fuel gas when the electric drive element is powered on.

In addition, the present invention does not limit the form of the driving assembly 600. The driving assembly 600 may also include a motor 610 and a winding shaft 620 as shown in FIG. 6. The two ends of the transmission cable are wound around the winding shaft 620 in opposite winding directions, respectively. The motor 610 is connected to the winding shaft 620 and can drive the winding shaft 620 to rotate. Therefore, no matter whether the motor 610 drives the winding shaft 620 to rotate forward or reverse, the winding shaft 620 can release one end of the driving cable 500 and wind the other end of the driving cable 500 at the same time, thereby driving the telescopic actuating rod 420 to the The guide wheels 510 are translated between them. The aforementioned forward rotation and reverse rotation of the winding shaft 620 define that the winding shaft 620 has two opposite rotation directions, rather than referring to a specific rotation direction.

In the vehicle door cover opening and closing mechanism of the present invention, the motor 610 drives the transmission cable 500 through the winding shaft 620 to drive the telescopic actuation rod 420 to translate to drive the mobile platform 400 to move. The telescopic actuation rod 420 can retract and allow the sliding tongue 410 to follow the ramp. 312 moves. When the sliding tongue 410 is located at the end of the ramp 312, the door cover 220 is located in the through opening 201 and closes the through opening 201. When the sliding tongue 410 is located at the other end of the linear segment 311, the door cover 220 is retracted from the through opening 201 and the input connector 100 is exposed through the through opening 201 to the housing 210. When the sliding tongue 410 leaves the ramp 312, the housing 210 covers the door cover 220.

When the door cover 220 is opened, the motor 610 rotates forward through the winding shaft 620 to drive the transmission cable 500 to pull the telescopic actuation rod 420 to translate to drive the mobile platform 400 to move. The ramp 312 of the channel 310 first guides the mobile platform 400 to drive the door cover 220 inward from the housing 210 and exit the opening 201, and the straight section 311 of the channel 310 then guides the mobile platform 400 to drive the door cover 220 to translate and completely exit the door. The range of 201 is hidden inside the housing 210. Therefore, the door cover 220 can be avoided from being hit when the charging plug is inserted.

When the door cover 220 is closed, the motor 610 reversely drives the transmission cable 500 through the winding shaft 620 to drive the retraction actuation rod 420 to translate to drive the moving platform 400 to move. The straight section 311 of the channel 310 then guides the moving platform 400 to drive the door cover 220 to translate into the range of the through opening 201. The ramp 312 of the channel 310 then guides the mobile platform 400 to drive the door cover 220 into the through opening 201 and close the through opening 201. The aforementioned forward rotation and reverse rotation of the motor 610 define that the motor 610 has two opposite rotation directions, rather than referring to a specific rotation direction.

Referring to FIG. 7, at the front end, the pair of winding shafts 620 a and 620 b can also be rotated by the gear set 630 and the two ends of the transmission cable 500 are wound around the winding shafts 620 a and 620 in the same winding direction. 620b. Therefore, whether the motor 610 is rotating forward or reverse, one of the winding shafts 620a (or 620b) releases one end of the transmission cable 500 while the other winding shaft 620b (or 620a) winds up the other end of the transmission cable 500.

Referring to FIG. 8, the driving cable 500 may also be ring-shaped and the driving assembly 600 includes a motor 610 and a roller 640. The roller 640 abuts the driving cable 500. The motor 610 drives the roller 640 to rotate and passes between the roller 640 and the driving cable 500. The friction force pulls the transmission cable 500. By the forward and reverse rotation of the motor 610, the drive cable 500 is pulled to pull the door cover 220 along the channel 310 toward the through opening 201 and close the through opening 201, or drive the door cover 220 to retract from the through opening 201.
