Compared with the prior art, the advantage of the present invention is that a first locking pin and a second locking pin are arranged on the mounting seat, and the driving assembly can drive the first locking pin and the second locking pin to act simultaneously, the first locking pin is engaged with the end of the second connecting member close to the motor, and the second locking pin is engaged with the end of the door panel away from the motor; the driving assembly includes a driving arm, a spline and a driven wheel, the spline is provided with a driving wheel, the driving wheel is meshed with the driven wheel, and the driven wheel is provided with a rotating shaft, and the rotating shaft passes through the mounting seat and is connected with the second locking pin.
[0003] However, the above-mentioned car charging port has the following disadvantages: the car charging port drives the driving wheel to rotate through the driving arm, and the driving wheel drives the driven wheel to rotate, and the driven wheel uses the four-link to drive the door panel to rotate. The opening driving force of the door panel relative to the mounting seat is completely brought by gear meshing, but the driving force provided by the gear transmission is not large enough, especially in winter, the gap between the door panel and the mounting seat is prone to ice and freezing, and the driving force of the above-mentioned driving component is not enough to break the ice, which easily leads to the door panel being unable to open. Therefore, it is urgent to develop a car charging port cover that provides a large output force driving structure. Utility Model Content
[0004] The utility model aims to provide a car charging port cover with a large output force driving structure, which has a large output force and can effectively break ice to open the cover.

[0006] By adopting the above technical scheme, when it is necessary to open the cover, the drive and control mechanism is used to drive the ejection mechanism to eject in a straight line, and the connecting rod assembly is pushed to flip outward under the ejection action of the ejection mechanism, thereby driving the cover to be in an open state relative to the base. If it is necessary to close the cover later, the drive and control mechanism drives the ejection mechanism to retract in a straight line direction, and the ejection mechanism drives the connecting rod assembly to flip inward and reset, thereby making the cover flip inward relative to the base to a closed state. The utility model is provided with an ejection mechanism connected to the output end of the drive and control mechanism, and the large ejection force generated in the straight line direction of the ejection mechanism can be used to drive the connecting rod assembly to generate a large flipping force outward, so that the cover can effectively break the ice and flip outward to an open state, which has a large output force and can effectively achieve the effect of breaking ice and opening the cover.

During the rotation of the driving arm, the linkage rod can play a buffering role to offset the offset stress caused by the angle change between the ejection sleeve and the driving arm, thereby extending the service life of the utility model.
[0011] The utility model is further configured as follows: one end of the linkage rod is hinged to the driving arm, and the hinge point of the linkage rod and the driving arm is located at the distal end of the connection point of the active connecting rod and the driving arm, and the other end of the linkage rod is hinged to the ejection sleeve.

[0016] By adopting the above technical solution, when the frozen coverage area between the dry plate and the base is large, the ejector sleeve extends outward under the driving force of the large output force, which will cause the linkage rod to deform, so that the support piece at the end of the ejector sleeve is pressed against the support surface at the bottom of the avoidance groove of the linkage rod, thereby improving the support strength between the ejector sleeve and the linkage rod, thereby enabling the linkage rod to withstand greater output stress, and effectively preventing the linkage rod from breaking due to the large output thrust.

[0022] The utility model is further configured as follows: an elastic member is provided between the base and the double gear, and the elastic member always has a movement tendency to drive the double gear to maintain meshing with the worm and the gear matching part.

The sliding portion 512 is guided and matched with the sliding groove 3a so that the ejection sleeve 51 is slidably arranged in the mounting box 3. The mounting box 3 is provided with a through hole for the ejection sleeve 51 corresponding to the ejection sleeve 51 for its extension. An internal threaded hole 51a is provided in the ejection sleeve 51 along the length direction. The screw 52 is threadedly connected to the internal threaded hole 51a. The drive control mechanism 4 can drive the screw 52 to rotate. The drive control mechanism 4 drives the screw 52 to rotate. By using the screw 52 and the ejection sleeve 51, the screw 52 is rotated. The groove matching and the sliding matching between the ejection sleeve 51 and the base 1 enable the ejection sleeve 51 to slide relative to the base 1 along the length direction of the screw rod 52, so that the ejection sleeve 51 can be ejected and retracted, thereby realizing the opening or closing action of the cover plate 2 relative to the base 1; the connecting rod assembly 6 includes a plurality of active connecting rods 61 and a driven connecting rod 62, and the cover plate 2 is connected to the base 1 through the plurality of active connecting rods 61 and the driven connecting rod 62.

The two ends of the linkage rod 7 are rotatably connected to the driving arm 611 and the ejection sleeve 51 by a hinged manner, and the hinged connection method improves the linkage rod 7 and the driving arm 611. The installation convenience between the movable arm 611 and the ejection sleeve 51 also makes the connection between the two ends of the linkage rod 7 and the driving arm 611 and the ejection sleeve 51 more stable, so that the three are not easily separated from each other; the two ends of the linkage rod 7 are provided with avoidance grooves 7a corresponding to the ejection sleeve 51 and the driving arm 611, and the ejection sleeve 51 and the driving arm 611 are rotatably connected to the avoidance grooves 7a at the corresponding ends of the linkage rod 7 through the pin shaft 71.
