channels

310a, 310b of the side may be in an overlapping configuration to compress the space occupied by the mechanism, in this embodiment, the

straight segments

311a, 311b of each

channel

310a, 310b of the side are in an overlapping configuration.

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 420, and the sliding tongue 420 is disposed in the

corresponding channel

310a, 310b and can move along the

310a and 310 b. When each of the sliding tongues 420 moves along the

corresponding slot

310a, 310b, it can guide the moving platform 400 to move at multiple positions simultaneously, and prevent the moving platform 400 from being deflected unexpectedly during the movement of the

straight sections

311a, 311 b. In the present embodiment, the mobile platform 400 extends out of a support foot 410, and the end of the support foot 410 extends out of the sliding tenon 420.

When the two sliding tongues 420 move in the

ramps

312a and 312b with different shapes, the two sliding tongues 420 push the moving platform 400 to rotate, so that one side of the door 220 rotates relative to the other side of the door 220 to enter and exit the charging port 201.

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.

In the present embodiment, the driving assembly 600 is disposed on the movable platform 400, and preferably disposed on the legs 410 of the movable platform 400. The drive assembly 600 includes a housing 610, a motor 620, and a gear assembly 630. The motor 620 and a portion of the gear train 630 are housed within the housing 610. The gear set 630 is connected to the motor 620 to be driven by the motor 620, and the gear set 630 engages the rack 500. As shown in fig. 3 and 6, the leg 410 of the mobile platform 400 penetrates through the housing 610 of the driving assembly 600, a slot 411 is formed on the leg 410, and the motor 620 is inserted into the slot 411 to increase the fixing structural strength of the leg 410, and at the same time, the volume of the driving assembly 600 can be reduced (since the driving assembly 600 moves along with the mobile platform 400, the volume of the driving assembly 600 can be reduced to reduce the space occupied by the moving path).

Referring to fig. 3 to 5, in the electric door cover mechanism of the invention, the motor 620 drives the driving assembly 600 to translate along the rack 500 to drive the moving platform 400 to move, and the translating section 510 of the rack 500 extends parallel to the

straight sections

311a and 311b of the

slots

310a and 310b to move the sliding tongue 420 along the

straight sections

311a and 311 b. The movement of the drive assembly 600 to the angled section 520 of the rack 500 causes the mobile platform 400 to rotationally translate along the

ramps

312a, 312b of the

channels

310a, 310 b. When the tongue 420 is positioned at the end of the

ramps

312a, 312b, the door 220 is positioned within the charging port 201 and closes the charging port 201. When the sliding tongue 420 is located at one end of the

straight line sections

311a and 311b far from the

ramps

312a and 312b, the door cover 220 is retreated 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 420 leaves the

ramps

312a, 312b, the housing 210 shields the door cover 220.

When the door 220 is opened, the motor 620 is rotated forward to drive the rack 500 to translate through the gear set 630, so as to drive the moving platform 400 to move. The

ramps

312a, 312b of the

slots

310a, 310b first guide the moving platform 400 to drive the door 220 to retract from the housing 210 to the inside away from the charging port 201, and then the

straight segments

311a, 311b of the

slots

310a, 310b guide the moving platform 400 to drive the door 220 to translate and completely retract from the range of the charging port 201 to 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 cover 220 is closed, the motor 620 rotates reversely to drive the rack 500 to translate through the gear set 630, so as to drive the moving platform 400 to move. The

straight sections

311a, 311b of the

slots

310a, 310b then guide the moving platform 400 to move the door 220 into the range of the charging port 201. The

ramps

312a, 312b of the

channels

310a, 310b then guide 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 620 are defined as two opposite rotation directions of the motor 620, and are not specific to a specific rotation direction.

The

channels

310a, 310b with different shapes have the

ramps

312a, 312b arranged in a non-parallel manner, when the sliding tongues 420 respectively move in the

ramps

312a, 312b arranged in a non-parallel manner, the pair of sliding tongues 420 can push the moving platform 400 to rotate, so that one side of the door cover 220 rotates relative to the other side of the door cover 220 to enter and exit the charging port 201, therefore, the requirement for the accuracy of the door cover 220 aligning with the charging port 201 can be reduced, and the requirement for the accuracy of the mechanism is lower, so that the manufacturing cost can be reduced.

The present invention is not limited to the rotation of the door 220 by the aforementioned manner. For example, by disposing the ramp 312a of the slot 310a and the inclined section 520 of the rack 500 in a non-parallel manner, when the driving assembly 600 moves along the inclined section 520 and the sliding tongue 420 moves along the corresponding ramp 312a, the moving platform 400 rotates to rotate one side of the door 220 relative to the other side of the door 220 to enter and exit the charging port 201, so that only one slot 310a is disposed on each side of the charging port 201.

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 door cover mechanism of the electric vehicle of the present invention has the channel 310a overlapped with another adjacent channel 310b, so that the space occupied by the

channels

310a, 310b can be compressed, thereby reducing the volume of the track assembly 300. Straight segments 311a of one channel 310a are configured to overlap with straight segments 311b of another, adjacent channel 310b to shorten the length of track assembly 300. However, depending on the required space, the ramp 312a of the slot 310a and the straight line segment 311b of the other slot 310b may be overlapped so that the

straight line segments

311a and 311b are disposed on the same plane and in a flat configuration, thereby reducing the thickness of the track assembly 300.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and should not be taken as limiting the scope of the present invention, but rather, the present invention is applicable to other equivalent variations within the spirit of the present invention.
