In other embodiments, the inner plate comprises an inner plate body and an arc-shaped plate, the arc-shaped plate is provided with an avoidance gap for avoiding the hinge seat, and the hinge seat is hinged in the avoidance gap. The hinged position of the transmission rod 4 and the inner plate 102 is arranged at the middle position of the inner plate 102, so that the transmission rod 4 drives the inner plate 102 to turn over, and then drives the charging port cover to turn over. In other embodiments, the hinge position of the drive rod and the inner plate may be moved in the front-rear direction of the inner plate in case that the drive rod drives the inner plate to be fully opened.
As shown in fig. 1, an ear plate 2 is arranged on one side of the inner plate 102 facing the guide rod 7, and the end part of the transmission rod 4 is hinged on the ear plate 2 through a first hinge shaft 3, so that the transmission rod is hinged on the inner plate 102, and the processing is convenient. In an embodiment thereof, a groove and a penetration hole through which the first hinge shaft is penetrated may be formed on the inner plate so that an end portion of the driving lever is hinged to the inner plate through the first hinge shaft.
In this embodiment, by adjusting the elastic force of the compression spring 10, when the charging flap is opened to the maximum, the gravity of the charging flap is exactly offset, and the power balance is ensured, so that the charging flap is kept at the maximum opening position. Of course, in other embodiments, a stop structure, such as a shoulder or stop tab, may be provided on the guide bar so that when the slider is slid to this position, it will not slide any more, and the charge door remains in the maximum open position.
In this embodiment, guide bar 7 includes injection moulding's body of rod, and body of rod one end integrated into one piece has articulated seat 14, and the body of rod is kept away from the one end of articulated seat 14 and is inlayed and be equipped with the screw rod, and the screw rod constitutes screw thread section 12, and the shaping is comparatively simple, the batch production of being convenient for, and the body of rod is made by plastics, and not only the quality is lighter, and the cost is lower moreover. In other embodiments, the guide bar is integrally a metal bar with external threads tapped thereon. Wherein, transfer line 4 and slider 8 are the working of plastics that have certain intensity, and pressure spring 10 and stopper 11 are the working of metal, when guaranteeing the operation requirement, have reduced the weight of whole device, and the device is whole to be triangle structure, and stability is also better. In other embodiments, at most one of the drive rod and the slider is made of plastic.
As shown in fig. 2 and 3, a latch hook is provided on the charging port cover, a latch tongue is provided on the vehicle body 101, and the latch tongue is controlled by an electromagnet. When the charging port cover is closed, the compression amount of the pressure spring 10 is the largest at the moment, the elastic acting force is the largest, and the component force applied to the transmission rod 4 by the pressure spring 10 is smaller because the included angle formed by the transmission rod 4 and the guide rod 7 is smaller, so that the force applied to the charging port cover is relatively smaller, namely the interaction force between the lock hook on the charging port cover and the lock tongue is smaller, the retraction resistance of the lock tongue driven by the electromagnet is smaller at the moment, and the unlocking of the charging port cover is facilitated. Although the compression spring 10 is continuously stretched in the opening process of the charging port cover, the elastic acting force of the compression spring 10 is gradually reduced, but the included angle formed by the transmission rod 4 and the guide rod 7 is gradually increased, so that the component force borne by the transmission rod 4 is not reduced too much due to the reduction of the elastic force of the spring, and the stable opening of the charging port cover can be ensured.
It should be noted that one charging port cover is provided with two driving mechanisms, and the two driving mechanisms are correspondingly arranged at the left side and the right side of the charging port cover so as to ensure the opening force and the stability of the charging port cover in the opening process. In other embodiments, one charging flap may correspond to only one drive mechanism, where a greater drive force is required for the drive mechanism.
