[0034] like Figure 1 - Fig.11 As shown, a charging port cover and a port cover assembly of the present invention include an actuator assembly 19, a positioning assembly, a gooseneck 21, a port cover 22 and a port tube 23; the port tube 23 is embedded in the body sheet metal; the port cover 22 is installed on the gooseneck 21 through a clamping structure; a through hole 24 is installed on the upper surface of the port tube 23; the other end of the gooseneck 21 is installed in the port tube 13 through the through hole 24; the actuator assembly 19 is installed at the connection between the gooseneck 21 and the port tube; the positioning assembly is arranged on one side of the port cover; a limit assembly for fixing the positioning assembly is embedded on the surface of the port tube;

[0035] A shielding rib 26 is installed on the back of the gooseneck 21 ; the shielding rib 26 is located opposite to the through hole 24 .

[0036] In this embodiment, the actuator assembly 19 includes a lower cover 13 and an upper cover 4; the lower cover 13 and the upper cover 4 are buckled with each other; a clutch gear shaft 12 is installed on one side of the lower cover 13 and extends to the outside of the upper cover 4; an end cover 11, a friction wheel 10 and a clutch gear 18 are installed in sequence above the clutch gear shaft 12 between the lower cover 13 and the upper cover 4; an output gear 2 is installed on the clutch gear shaft 12 extending to the outside of the upper cover 4; a DC motor 6 and a gear shaft 9 are installed on the other side of the lower cover 13, and a worm gear 8 is installed on the gear shaft 9; a worm 7 is installed at one end of the DC motor 6; the worm wheel 8 and the worm 7 are meshed with each other; a double gear 17 is meshed between the worm wheel 8 and the clutch gear 18.

[0037] In this embodiment, a special-shaped sealing ring 5 is installed between the lower cover 13 and the upper cover 4; a shaft sleeve 14 is installed between the clutch gear 18 and the upper cover 4; a circular sealing ring is installed between the upper cover 4 and the output gear 2; a PCB mainboard 15 is installed on one side of the lower cover 13; and a PTC component is installed on one side of the PCB mainboard 15.

[0038] In this embodiment, a connecting transmission rod 20 is installed at one end of the gooseneck 21 ; the connecting transmission rod 20 is meshed with the output gear 2 .

[0039] In this embodiment, a decorative plate 25 is installed on the through hole 24 .

[0040] In this embodiment, the positioning assembly includes a positioning pin 40 and a positioning boss 41 ; the limiting assembly includes a first limiting groove 42 and a second limiting groove 43 ; the positioning pin 40 is installed in the first limiting groove 42 ; the positioning boss 41 is installed in the second limiting groove 43 .

[0041] In this embodiment, the special-shaped sealing ring 5 and the upper cover 4 are both made of two-color injection molding; the PTC element is connected in series with the DC motor 6; a rotating shaft 44 is installed at one end of the gooseneck 21; and the connecting transmission rod 20 is installed inside the rotating shaft 44.

[0042] In this embodiment, the friction wheel 10 is inserted into the clutch gear 18 and is clamped together by the end cover 11 to form a clutch mechanism. The clutch gear and the friction wheel generate a damping torque through friction. When the torque value received by the clutch mechanism is less than the damping torque, the clutch mechanism as a whole outputs motion and power to the output gear to drive the operation of the cover; when the torque value received by the clutch mechanism is greater than the damping torque, the clutch gear is disengaged from the friction wheel, and the excessive torque at the output end cannot be transmitted to the clutch gear; due to the action of the clutch structure, after the torque value at the output end overcomes the torque value of the clutch mechanism, the friction wheel and the clutch gear rotate relative to each other, and the torque value no longer continues to increase, thereby protecting the entire gear transmission mechanism from damage.

[0043] In this embodiment, power is input to the DC motor 7 through the PCB mainboard 15, driving the DC motor to rotate, driving the worm 7 to rotate, driving the worm wheel 8, the double gear 17, the clutch structure, and the output gear 2 to rotate, outputting motion and power to the cover assembly, driving the cover to open or close.

[0044] In this embodiment, a PTC element is connected in series on the PCB board assembly and connected in series with the motor power input terminal to form a motor control circuit. When the motor is stalled, the current value of the control circuit is the motor stall current, which is much larger than the motor working current. The motor is similar to a pure resistor, and the temperature rises rapidly, causing the PTC resistance to increase rapidly. When the PTC resistance reaches the critical resistance, the PTC conductive link becomes narrower or broken, and the current is quickly cut off, thereby quickly and accurately limiting and protecting the circuit and protecting the motor from burning.

[0045] In this embodiment, G is the gap between the flap and the body sheet metal, and D is the minimum envelope distance from the flap to the edge of the sheet metal. When the flap is not positioned accurately, the dimension G changes. When G becomes smaller, the corresponding dimension D becomes smaller, and the distance between the lowest point of the flap and the body sheet metal becomes smaller, which easily causes motion interference. The positioning pin plays a role in ensuring that the gap of the flap is uniform and that the flap can be flipped over.

[0046] In this embodiment, the actuator assembly 19 transmits motion and power from the output gear 2 to the connecting transmission rod 20, driving the connecting transmission to rotate. The connecting transmission rod and the gooseneck 21 are connected as a whole through a clip and a key, and the gooseneck and the cover 22 are connected as a whole through a clip, and the three parts are assembled into a cover assembly. The rotation of the connecting transmission rod drives the cover assembly to open, so that the vehicle can be refueled or charged; the cover assembly is closed to protect the vehicle refueling or charging socket. The clutch mechanism inside the actuator ensures that when the cover is interrupted by external force (abuse) during the opening or closing process, the actuator transmission mechanism can be protected from damage. In the event of a power outage or power failure, the charging cover can be manually opened or closed without starting the vehicle.

[0047] In this embodiment, in order to control the surface difference and gap between the cover and the sheet metal, a positioning pin and a positioning boss structure are added between the cover components. The positioning pin and the positioning boss are arranged on the gooseneck hinge, and the cover and the gooseneck are connected together by a buckle. Figure 2 : The upper and lower sides of the locating pin cooperate with the upper and lower sides of the mouth tube locating hole respectively to realize the Z-direction positioning of the mouth cover; the left and right sides of the locating pin cooperate with the left and right sides of the mouth cover locating hole respectively to realize the X-direction positioning of the mouth cover; the bottom surface of the positioning boss cooperates with the bottom surface of the mouth tube to realize the Y-direction positioning of the mouth cover, ensuring that the position of the mouth cover on the body is fixed and accurate, so that the surface difference and gap between the mouth cover and the body can be controlled, ensuring the product appearance.

[0048] The beneficial effects of the present invention are as follows: by installing an actuator assembly at one end of the mouth cover; the operation of the mouth cover is improved to be intelligent, energy-saving and efficient; by designing a PTC element, the DC motor is protected from being burned when the motor is blocked; by arranging a clutch assembly inside the actuator assembly, the mouth cover is prevented from being damaged when subjected to abuse force, and the transmission mechanism is protected from damage; by adopting two-color molding of the sealing ring and the upper cover, the sealing level of the actuator is improved, and automatic assembly is easy to achieve, which greatly improves the production efficiency; by adding a decorative structure to the back of the gooseneck, after the mouth cover is opened, the gooseneck outlet hole is invisible, the mouth tube has a beautiful appearance, a simple structure, and is integrated with the gooseneck, there is no need to develop a mold separately, and the product development and production costs are reduced; by arranging a positioning assembly on one side of the mouth cover, the mouth cover is fixed to each other through the positioning assembly and the limit assembly arranged on the mouth tube, so as to control the surface difference and gap value between the mouth cover and the outer panel of the vehicle body.

[0049] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
