The channel 310 includes a straight line segment 311 extending substantially parallel to the outer casing 210 and inclined from one end of the straight line segment 311 toward the charging port 201. An extended ramp 312. In this example, a plurality of channels 310 having the same shape are formed on the track assembly 300, and each channel 310 is overlapped with another channel 310. Preferably, the ramps 312 of the channels 310 are respectively separated from the other slots. The straight line segments 311 of the track 310 are arranged in an overlapping manner. A sleeve 320 is fixedly disposed on the rail assembly 300. In the embodiment, the sleeve 320 is preferably formed in the track group. On piece 300. The sleeve 320 and the straight section 311 of the channel 310 are arranged parallel to each other. One side of the sleeve 320 is provided with a longitudinal groove 321 , and the other side of the sleeve 320 is provided with a transmission port 322 .

The mobile platform 400 is movably disposed on the track assembly 300. The mobile platform 400 is provided with at least one slider 410 disposed in the corresponding channel 310 and movable along the channel 310, thereby defining the mobile platform 400. Displacement path. In the embodiment, the mobile platform 400 is preferably provided with a plurality of sliding blocks 410 corresponding to the plurality of channels 310. The sliding blocks 410 are respectively disposed in the corresponding channels 310 and can respectively correspond to corresponding ones. The channel 310 moves. As each of the sliders 410 moves along the corresponding channels 310, a plurality of positional movements on the mobile platform 400 can be guided thereby preventing the mobile platform 400 from deflecting during movement.

The door cover 220 is disposed on the mobile platform 400. The door cover 220 preferably has the same structure as the outer casing 210, and the outer shape of the door cover 220 is continuous with the outer shape of the outer casing 210 at the periphery of the charging port 201.

The rack 500 is disposed corresponding to the inner side 212 of the outer casing 210, and the rack 500 is disposed parallel to the straight section 311 of the channel 310 and is longitudinally translatable. The rack 500 is threaded within the sleeve 320 and the telescoping actuator rod 420 is threaded out of the sleeve 320 through the longitudinal slot 321 . One side of the rack 500 protrudes laterally from a telescopic actuating lever 420, and the telescopic actuating lever 420 is coupled to the mobile platform 400. Specifically, the telescopic actuating lever 420 includes a sliding rod 421 and a sleeve 422. One end of the sliding rod 421 is disposed in the sleeve 422, and one of the sliding rod 421 and the sleeve 422 is connected to the moving platform 400. The other of the slide bar 421 and the sleeve 422 is coupled to the rack 500. In the present embodiment, the sleeve 422 is connected to the slide bar 421 of the mobile platform 400 to connect the rack 500. However, the sleeve 422 can also be interchangeably disposed, and the invention is not limited thereto.

In the present embodiment, the drive assembly 600 includes a motor 610 and a gear set 620. Gear set 620 is coupled to motor 610 and is drivable by motor 610, and gear set 620 engages rack 500 via transmission port 322.

In the electric vehicle charging port opening and closing mechanism of the present invention, the motor 610 drives the rack 500 to move through the gear set 620 to drive the moving platform 400 to move, and the telescopic actuating rod 420 can expand and contract to allow the sliding block 410 to move along the ramp 312. When the 410 is located at the end of the ramp 312, the door cover 220 is located in the charging port 201 and closes the charging port 201. When the slider 410 is located at the other end of the straight section 311, the door cover 220 is retracted from the charging port 201 and the charging socket 100 exposes the outer casing 210 through the charging port 201. When the skid 410 leaves the ramp 312, the outer casing 210 covers the door cover 220.

When the door cover 220 is opened, the motor 610 rotates through the gear set 620 to drive the rack 500 to translate and move the mobile platform 400. The ramp 312 of the channel 310 first guides the mobile platform 400 to drive the door cover 220 to retreat inwardly from the outer casing 210 away from the charging port 201. The straight section 311 of the channel 310 then guides the mobile platform 400 to drive the door cover 220 to translate completely away from the charging port. The range of 201 is concealed within the outer casing 210. It is therefore possible to avoid collision of the door cover 220 when the charging plug is inserted.

When the door cover 220 is closed, the motor 610 reverses the transmission of the rack 500 through the gear set 620 to drive the mobile platform 400 to move. The straight section 311 of the channel 310 then directs the mobile platform 400 to cause the door cover 220 to translate into the range of the charging port 201. The ramp 312 of the channel 310 then directs the mobile platform 400 to move the door cover 220 into the charging port 201 to close the charging port 201. The aforementioned motor 610 forward rotation and reverse rotation system definition motor 610 have two opposite rotation directions instead of a specific rotation direction.

The advantage of the electrically driven door cover 220 is that even if the owner finds that the door cover 220 is not closed after getting on the vehicle, the door cover 220 can be closed in the vehicle without having to get off the vehicle to manually close the door cover 220.

The electric vehicle charging port opening and closing mechanism of the present invention pushes the moving platform 400 by the telescopic actuating lever 420, and allows the moving platform 400 to move perpendicularly to the rack 500. The simple linear rack 500 can drive the mobile platform 400 biaxially. Displacement.

In the electric vehicle charging port opening and closing mechanism of the present invention, each of the channels 310 overlaps with the other channel 310, so that the space occupied by the channel 310 can be compressed, which reduces the volume of the track assembly 300. The slope 312 of at least one of the channels 310 overlaps with the straight line segment 311 of the other channel 310 such that the straight segments 311 are disposed on the same plane and are in a flat configuration to shorten the thickness of the track assembly 300. However, depending on the required space, the straight segments 311 may also be arranged to overlap to shorten the length of the track assembly 300.

The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and other equivalent variations of the patent spirit of the present invention are all within the scope of the invention.
