Figure 2As shown, the protection component 4 is arranged in the base frame 1, and the protection component 4 includes a support block 41, a second spring 44 and a baffle 42 slidably connected to the support block 41, the second spring 44 is arranged in the support block 41 and pulls back the baffle 42, and the second spring 44 has a pulling effect. When the locking member 15 is separated from the baffle 42, the second spring 44 pulls back the baffle 42 to retract into the support block 41, so that the charging port is exposed, and a slide groove 43 is formed in the support plate 321, and the baffle 42 slides in the slide groove 43. The baffle 42 A card slot 421 matching with the locking piece 15 is provided on it, and the support block 41 is arranged in the base frame 1. The protection component 4 is convenient for operating the protection of the charging port and is connected to the base frame 1 at the same time to reduce the risk of loss. Compared with the charging port protection plate with a transmission threaded connection, its practical effect is improved. When charging the electric vehicle, the charging gun is inserted into one of the slow charging ports 12 or the fast charging ports 14, and the other uncharged baffle 42 is pulled downward so that the baffle 42 is stuck on the locking piece 15, so as to fix the baffle 42 and then seal the charging port.

[0033] As an embodiment further provided by the present invention, a rubber plate 45 matching with the slow charging port 12 and the fast charging port 14 is provided on the baffle 42 , and the rubber plate 45 improves the sealing performance between the baffle 42 and the slow charging port 12 or the fast charging port 14 .

[0034] As an embodiment further provided by the present invention, the base frame 1 has an inclined surface 13, and an arc groove 11 matching the cover plate 2 is symmetrically opened on the inclined surface 13. The inclination angle of the inclined surface 13 is 15°. When it rains, rainwater enters the base frame 1 and will flow into the arc groove 11 along the inclined surface 13 and then flow out of the base frame 1 through the arc groove 11.

[0035] As an embodiment further provided by the present invention, a sealing ring 22 is provided on the cover plate 2 and fits with the base frame 1, and a drainage groove 21 connected with the arc groove 11 is symmetrically provided on one side of the cover plate 2. The sealing ring 22 improves the sealing between the cover plate 2 and the base frame 1, and the drainage groove receives the water flow in the base frame 1 (a small amount of rainwater will enter the base frame 1 on rainy days) to make the water flow out of the base frame 1.

[0036] As an embodiment further provided by the present invention, the locking member 15 includes a sliding rod 151 and a tilting block 153 arranged at the end of the sliding rod 151, a first spring 152 between the tilting block 153 and the base frame 1, the sliding rod 151 is slidably arranged on the base frame 1, and the tilting block 153 is engaged with the slot 421, and the tilting angle of the tilting block 153 is 65°. When the baffle 42 is engaged with the locking member 15, the tilting block 153 will be pushed to make the sliding rod 151 slide upward. When sliding to a certain distance, the spring force of the first spring 152 pushes the sliding rod 151 to make the tilting block 153 engage in the slot 421 of the baffle 42, thereby fixing the baffle 42.

[0037] As an embodiment further provided by the present invention, the transmission assembly 3 includes a rotating shaft 31, a cover 32 and a support plate 321 engaged with the cover 32, one end of the rotating shaft 31 cooperates with the cover 2, and a transmission wheel 36 located in the cover 32 is provided at the other end thereof, the support plate 321 and the cover 32 are provided with meshing worm gears 34 and worm 33 which rotate in sequence, the worm gear 34 cooperates with the transmission wheel 36, and output is performed through the motor 35, so that the worm 33 on the output shaft drives the worm wheel 34 to rotate, and the worm gear 34 links the transmission wheel 36 to drive the rotating shaft 31 to rotate, so as to control the cover 2 to flip, a switch is provided on the outside, and the switch is connected to the motor 35 through an electrical signal to flip the set angle, and when the switch is pressed, the cover 2 is reset and fits the base frame 1 to protect the slow charging port 12 and the fast charging port 14.

[0038] As an embodiment further provided by the present invention, a pulley is provided on the worm wheel 34, and a synchronous belt is provided between the pulley and the transmission wheel 36. The worm wheel 34 drives the pulley to rotate, and the pulley drives the transmission wheel 36 to rotate through the synchronous belt, thereby rotating the shaft 31.

[0039] As an embodiment further provided by the present invention, the number of teeth of the pulley is smaller than the number of teeth of the transmission wheel 36, so that the cover plate 2 can be turned over more smoothly and the turning jamming phenomenon can be reduced.

[0040] As a further embodiment of the present invention, one end of the rotating shaft 31 is provided with rectangular blocks 310 in a circular array that match the cover plate 2. The rectangular blocks 310 increase the contact area with the cover plate 2, so that the rotating shaft 31 can better link with the cover plate 2 to rotate when it rotates.

[0041] Working principle: First, when the charging port is not charging, the two baffles 42 can be pulled to snap into the locking piece 15, so that when not charging, the fast charging port 14 and the slow charging port 12 are protected from dust. When the electric car needs to be charged, when the charging gun is inserted into one of the charging ports, the baffle 42 on the upper end of the non-charging port on the other side is slid, so that the slot 421 on the baffle 42 is snapped into the inclined block 153 of the locking piece 15, so as to seal the non-charging port and improve the protection of the charging port.

[0042] The technical solution of the above utility model provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single.
