In this example, the track assembly 300 is formed with a plurality of channels 310 having the same shape, each channel 310 is disposed to overlap another channel 310, and preferably, the ramp 312 of each channel 310 is disposed to overlap the straight section 311 of another channel 310. A sleeve 320 is fixedly disposed on the track assembly 300, and in the present embodiment, the sleeve 320 is preferably formed on the track assembly 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 moving platform 400 is movably disposed on the rail assembly 300, and the moving platform 400 is provided with at least one sliding tongue 410, and the sliding tongue 410 is disposed in the corresponding channel 310 and can move along the channel 310, thereby defining a displacement path of the moving platform 400. In the present embodiment, the movable platform 400 is preferably provided with a plurality of sliding tongues 410 corresponding to the slots 310, and each sliding tongue 410 is respectively disposed in each corresponding slot 310 and can move along each corresponding slot 310. When each of the sliding tongues 410 moves along the corresponding one of the grooves 310, it is possible to guide the movement of a plurality of positions on the moving platform 400, thereby preventing the moving platform 400 from deflecting during the movement.

The door 220 is disposed on the mobile platform 400, the door 220 and the housing 210 are preferably of the same metal plate structure, and the shape of the door 220 is continuous with the shape of the housing 210 at the periphery of the charging port 201.

The rack 500 is disposed in correspondence with the inner side 212 of the housing 210, the rack 500 being disposed parallel to the straight section 311 of the channel 310 and being longitudinally translatable. The rack 500 is disposed through the sleeve 320, and the telescopic actuating rod 420 passes through the sleeve 320 through the longitudinal slot 321. A telescopic actuating rod 420 is protruded laterally from one side of the rack 500, and the telescopic actuating rod 420 is connected to the moving platform 400. Specifically, the telescopic actuating rod 420 includes a sliding rod 421 and a sleeve 422, one end of the sliding rod 421 is inserted into the sleeve 422, one of the sliding rod 421 and the sleeve 422 is connected to the moving platform 400, and the other of the sliding rod 421 and the sleeve 422 is connected to the rack 500. In the embodiment, the sleeve 422 is preferably connected to the sliding rod 421 of the moving platform 400 and connected to the rack 500, but the configuration may be reversed, and the invention is not limited thereto.

In the present embodiment, the driving assembly 600 includes a motor 610 and a gear set 620. The gear set 620 is connected to the motor 610 to be driven by the motor 610, and the gear set 620 engages the rack 500 through the transmission port 322.

According to the charging port opening and closing mechanism of the electric vehicle, the motor 610 drives the rack 500 to translate through the gear set 620 so as to drive the moving platform 400 to move, the telescopic actuating rod 420 can be stretched and contracted so as to allow the sliding tenon 410 to move along the ramp 312, and when the sliding tenon 410 is positioned at the tail end of the ramp 312, the door cover 220 is positioned in the charging port 201 and closes the charging port 201. When the sliding tongue 410 is located at the other end of the straight line segment 311, the door cover 220 is withdrawn from the charging port 201 and the charging socket 100 is exposed out of the housing 210 through the charging port 201. When the tongue 410 leaves the ramp 312, the housing 210 covers the door 220.

When the door 220 is opened, the motor 610 is rotated forward to drive the rack 500 to translate through the gear set 620, so as to drive the moving platform 400 to move. The ramp 312 of the slot 310 first guides the moving platform 400 to drive the door 220 to retract from the housing 210 and away from the charging port 201, and the straight section 311 of the slot 310 then guides the moving platform 400 to drive the door 220 to move and move back completely away from the range of the charging port 201 and be hidden inside the housing 210. It is possible to avoid collision against the door cover 220 when the charging plug is inserted.

When the door 220 is closed, the motor 610 rotates reversely to drive the rack 500 to translate through the gear set 620, so as to drive the moving platform 400 to move. The straight section 311 of the slot 310 then guides the moving platform 400 to move the door 220 into the range of the charging port 201. The ramp 312 of the channel 310 then guides the mobile platform 400 to bring the door 220 into the charging port 201 to close the charging port 201. The forward and reverse rotation of the motor 610 defines that the motor 610 has two opposite rotation directions, not a specific rotation direction.

The electrically driven door 220 has an advantage in that the door 220 can be operated to close in the vehicle even if the owner finds that the door 220 is not closed after getting on the vehicle, without manually closing the door 220 by getting off the vehicle.

The opening and closing mechanism for the charging port of the electric vehicle of the present invention allows the moving platform 400 to move perpendicular to the rack 500 by pushing the moving platform 400 by the telescopic actuating rod 420, and can drive the moving platform 400 to perform biaxial displacement by using the simple linear rack 500.

In the charging port opening and closing mechanism for the electric vehicle according to the present invention, each channel 310 is overlapped with another channel 310, so that the space occupied by the channels 310 can be reduced, which reduces the volume of the track assembly 300. The ramp 312 of each channel 310 is overlapped with the straight line segment 311 of another channel 310, so that the straight line segments 311 are arranged on the same plane and in a flat configuration to reduce the thickness of the track assembly 300. However, depending on the space requirement, the straight segments 311 may be arranged in an overlapping manner to shorten the length of the track assembly 300.

The above-mentioned embodiments are merely preferred embodiments for fully illustrating the present invention, and the scope of the present invention is not limited thereto. The equivalent substitution or change made by the technical personnel in the technical field on the basis of the invention is all within the protection scope of the invention. The protection scope of the invention is subject to the claims.
