[0015] 1. The present invention provides an adsorption mechanism. When charging a new energy vehicle through a charging gun, the charging head of the charging gun is inserted into the charging port of the new energy vehicle. During the insertion process, the push block will push the slide plate to move to one side under the action of pressure, and the slide plate will push the push plate to move synchronously when moving. At this time, the push plate will drive the piston pad to slide toward the inside of the notch. The air pressure inside the notch will increase with the sliding of the piston pad. The gas inside the notch will be transported to the inside of the pull-out groove through the air hole after being compressed.

When the charging head is fully inserted into the charging port of the new energy vehicle, the suction cup will be fully adsorbed on the smooth outer wall of the charging port, so as to fix the charging of the charging gun through the adsorption of the suction cup, so as to improve the charging effect of the charging gun on the new energy vehicle, and prevent the charging line from dragging the charging gun due to the gravity of the charging line during the charging process, causing the charging gun to deviate downward, thereby affecting the charging of the new energy vehicle;

[0016] 2. The present invention provides an adsorption mechanism and an anti-slip mechanism. When the charging head is inserted into the charging port, the piston pad will contact the swing plate during the sliding process. As the charging head continues to be inserted, the piston pad will push one end of the swing plate to deflect to one side, and the other end of the swing plate will deflect in the opposite direction under the action of the rotating shaft. The other end of the swing plate will push the push rod to slide to one side during the deflection, and the push rod will push the anti-slip plate to slide toward one side of the charging port during the sliding. At this time, the tooth block will act on the bottom of the charging port and the charging head. Since one end of the tooth block is tilted upward, the charging stability of the charging gun can be improved through the action of multiple tooth blocks, and the charging gun can be prevented from falling off due to the gravity of the charging line during charging, thereby affecting the charging of the new energy vehicle.

When the charging head 2 is inserted into the charging port, the piston pad 20 will contact the swing plate 29 during the sliding process, and as the charging head 2 continues to be inserted, at this time, the piston pad 20 will push one end of the swing plate 29 to deflect to one side, and the other end of the swing plate 29 will deflect in the opposite direction under the action of the rotating shaft 28, and the other end of the swing plate 29 will push the push rod 33 to slide to one side during the deflection, and the push rod 33 will push the anti-skid plate 31 to slide toward one side of the charging port during the sliding. At this time, the tooth block 32 will act on the charging port and the bottom of the charging head 2, and because one end of the tooth block 32 is tilted upward, therefore, through the action of multiple tooth blocks 32, the charging stability of the charging gun can be improved, and the charging gun can be prevented from falling off during charging due to the gravity of the charging line 6 during charging, thereby affecting the charging of the new energy vehicle.
