Automatic cover opening and closing mechanism

Abstract

The invention discloses an automatic cover opening and closing mechanism. The automatic cover opening and closing mechanism comprises a base assembly, a hinge plate, a cover plate, a driving rocker arm, a driven rocker arm, an actuator and a contact switch, wherein an inwards-concave groove structure is arranged on the base assembly, one end of the driving rocker arm and one end of the driven rocker arm are assembled on the base assembly through a rotating pair, the other end of the driving rocker arm and the other end of the driven rocker arm are assembled on the hinge plate through a rotating pair, the hinge plate, the driving rocker arm, the driven rocker arm and the base assembly form a parallel four-rod structure, a cover plate is fixed to the top of the hinge plate, the contact switch is arranged at the front end of the base assembly, the cover plate is provided with a convex rib used for triggering the contact switch, the actuator is triggered through the contact switch, and the actuator is used for driving the driving rocker arm to rotate around the rotating pair of the driving rocker arm and the base assembly, so that the cover plate covers the groove structure of the base assembly or is opened in parallel. According to the automatic cover opening and closing mechanism, by realizing translation type side-moving opening of the cover plate, the possibility that dust enters a cover opening is greatly reduced, and automation of opening and closing actions of the opening cover can be realized.

Description

technical field [0001] The invention relates to the technical field of auto parts, and relates to a cover mechanism, in particular to an automatic opening and closing cover mechanism for a refueling / charging port cover. Background technique [0002] The refueling / charging port cover of the car basically adopts a flip-type opening method. When the vehicle is driving, a lot of dust will adhere to the outer surface of the cover. During charging or refueling, when the cover is opened, dust can easily enter the inside of the cover. , For gasoline vehicles, dust and other impurities enter the fuel tank, seriously affecting the life of the oil filter and affecting the normal operation of the engine; for charging vehicles, dust entering may cause plug short circuit, poor contact and other phenomena. In addition, the refueling / charging port cover of the prior art must be manually opened and closed, and the cover takes up a large space after being opened, and most of the refueling / cha...

[0002] The refueling / charging port cover of the car basically adopts a flip-type opening method. When the vehicle is driving, a lot of dust will adhere to the outer surface of the cover. During charging or refueling, when the cover is opened, dust can easily enter the inside of the cover. , For gasoline vehicles, dust and other impurities enter the fuel tank, seriously affecting the life of the oil filter and affecting the normal operation of the engine; for charging vehicles, dust entering may cause plug short circuit, poor contact, etc.

In addition, the refueling / charging port cover of the prior art basically needs to be manually opened and closed, and the cover occupies a large space after being opened, and most of the refueling / charging port covers have no automatic function
