In this embodiment, the fixed part 11 The part 11 can actually be regarded as a fixed frame around the charging port. As shown in Figure 2, the through hole opened in the middle of the fixed part 11 can be regarded as the insertion position of the charging plug during charging, and the moving part 12 can actually be regarded as a It is a charging port cover that can be opened and closed, and the driving mechanism 2 drives the moving part 12 to move back and forth, so as to realize the opening and closing of the charging port cover.

Specifically, the drive mechanism 2 includes a drive rod 21 and a drive motor 22, wherein one end of the drive rod 21 is rotationally connected to the moving part 12, and the drive motor 22 is relatively fixed to the fixed part 11, and the output end of the drive motor 22 is connected to the drive The other end of the rod 21 is driven and connected, so that when the driving motor 22 outputs power, the driving rod 21 can drive the moving part 12 to move relative to the fixed part 11 through rotation; as shown in Figure 5 of the specification, in a possible implementation of this specification In the mode, the driving rod 21 can be driven and connected with the output end of the driving motor 22 through the connecting shaft 23, and the connecting shaft 23 is driven to rotate by the driving motor 21, thereby driving the driving rod 21 connected to the connecting shaft 23 to rotate. The transmission method is simple and direct, reducing Electric energy loss; in another possible embodiment of this description, as shown in accompanying drawing 6 of the description, the drive rod 21 can realize the rotational connection with the moving part 12 through the pivot pin, but the present invention is not limited to this, it can The connection structure to the rotation connection can all be within the scope of protection of this description.

Specifically, as shown in Figures 1-3 of the specification, the limit mechanism 3 includes an auxiliary rod 31, one end of which is rotatably connected to the fixed part 11, as shown in Figure 7, in a possible implementation of the specification , the rotation connection can be realized by a pivot pin, and the other end of the auxiliary rod 31 is relatively rotated with the moving part 12, so that the auxiliary rod 31 can cooperate with the driving rod to limit the moving part 12 to move along the preset track; wherein, if there is no auxiliary rod 31 , then the moving part 12 is likely to perform rotational movement along the rotation of the driving rod 21, and the setting of the auxiliary rod 31 can play a limiting role when the moving part 12 appears to rotate, so that the moving part 12 finally moves in parallel according to the preset track , Compared with the traditional four-link structure, the charging port cover can be moved by only two rods, which greatly reduces the occupied space and weight. At the same time, the transmission structure is simpler and the transmission efficiency is higher.

As shown in Figure 4 of the specification, it is the preset trajectory when the moving part 12 moves. Assume that the vehicle’s forward direction is the positive direction of X direction, the backward direction is the negative direction of X direction, and the lateral sides of the vehicle are Y direction. , the vertical direction is the Z direction, and the preset trajectory is to reciprocate along the positive and negative directions of the X direction, so as to realize the opening and closing of the charging port cover; it should be noted that when the charging port cover is closed, the moving part 12 is in contact with the fixed part 11 is strictly covered, that is, the edge of the moving part 12 is matched with the outer surface of the vehicle, and when the charging port cover moves back and forth, the moving part 12 actually slightly protrudes from the outer surface of the vehicle, and when it moves back and forth outside, the moving part 12 just When it is opened, a small amount of displacement will be generated in the Y direction along the direction away from the vehicle.

Rotate or rotate counterclockwise. At this time, the driving rod 21 and the auxiliary rod 31 may partially overlap in the Z direction, but they are completely misaligned in the horizontal direction. The auxiliary rod 31 is arranged on the side close to the negative direction of the X direction; in this embodiment, considering the utilization rate of the lifting space, the driving rod 21 and the auxiliary rod 31 can be completely misplaced in the Z direction to reduce the occupied space, for example , as shown in Figure 1, the auxiliary rod 31 is arranged above the driving rod 21, and in the Z direction, there is a certain gap between the two to ensure that they will not contact each other during the rotation process.

Specifically, as shown in accompanying drawing 1 of the specification and accompanying drawing 8 of the specification, the limit mechanism 3 may also include a stabilizing rod 32, which is arranged on the inner surface of the moving part 12 and is rotatably connected to one end of the auxiliary rod 31, That is, the auxiliary rod 31 can be indirectly rotatably connected to the moving part 12 through the stabilizing rod 32; wherein, in a possible embodiment of the specification, the stabilizing rod 32 can be set as a structure capable of rotating around its central axis, so as to balance the rotation of the auxiliary rod 31 In this embodiment, the stabilizing bar 32 can be relatively stationary relative to the moving part 12 so as to improve the overall perceived stiffness of the moving part 12 .

When the moving part 12 is in the closed state, the locking member 41 locks and unlocks the cover main body 1 by reciprocating movement, preventing the moving part 12 from accidentally opening and polluting the internal charging port; while the locking motor 42 is fixedly connected to the body of the vehicle, and The output end of the locking motor 42 is drivingly connected to the locking member 41 for providing power for the reciprocating movement of the locking member 41 .

Specifically, as shown in Figure 9 of the specification, the locking member 41 includes a rod portion 410 and at least one locking portion 411, wherein the rod portion 410 is directly driven and connected to the output end of the locking motor 42, so that the rod portion 410 can be driven along the rod portion. 410 reciprocates in the axial direction, thereby driving the entire locking member 41 to reciprocate in the axial direction, that is, to move in the X direction; and the locking part 411 protrudes from the rod part 410 along the circumferential direction of the rod part 410, and is used for driving The rod 21 and/or the moving part 12 are locked to ensure that the moving part will not be accidentally opened when it is in the closed state, and the charging port will not be exposed to contaminate the charging port.

In a possible implementation of this specification, a locking part 411 is provided in the locking part 41, and the locking part 411 is used for locking with the driving rod 21. Correspondingly, a The locking hole 5, the locking hole 5 and the locking part 411 are correspondingly used to lock the cover main body 1, wherein, taking the direction shown in Figure 9 as a reference, the locking member 41 moves to the right along the X direction, and the locking The locking part 411 is inserted into the locking hole 5 on the driving rod 21, so that the driving rod 21 cannot move to realize the locking function. Otherwise, the locking part 41 moves leftward along the X direction, and the locking part 411 is locked from the locking part on the driving rod 21. Pull out from the hole 5, so that the driving rod 21 can rotate without restriction, realizing the unlocking function.

When it is necessary to open the charging port cover, firstly the locking motor 42 outputs power to control the locking member 41 to move along the X direction, the locking part 411 is released from the locking hole 5 and unlocked, and then the driving motor 22 drives the driving rod 21 to rotate, and then Drive the moving part 12 to move, and at the same time, the auxiliary rod 31 is passively rotated to cooperate with the driving rod 21 to limit the moving part 12 to move along the preset trajectory, that is, to open the charging port cover along the X direction; otherwise, when the charging port cover needs to be closed, drive The motor 22 reverses, drives the driving rod 21 to rotate in the reverse direction, and then drives the moving part 12 to move in the reverse direction. The moving part 12 can completely cover the fixed part 11, that is, the charging port cover is completely closed. At this time, the locking motor 42 is reversed to control the locking part 41 to move in the opposite direction along the X direction, and the locking part 411 is inserted into the locking hole 5 to complete locking.
