Description

TECHNICAL AREA

[0001] The present disclosure relates to a charging port hatch system. BACKGROUND

[0002] An electric vehicle (EV) and a hybrid electric vehicle (HEV) can have a charging port for connecting an electrical plug (charging plug) to the vehicle. The electrical plug can be connected to a charging station, which supplies the vehicle with power. Additionally, the EV and the HEV may have a charging port access panel that covers and exposes the charging port.

[0003] The charging port hatch system can comprise a housing with an opening that communicates with the charging port, a hatch that is movably mounted relative to the housing, and an actuator configured to move the hatch. Prior art charging port hatch systems may include a gooseneck hinge charging port hatch system, a multi-section charging port hatch system, and the like.

[0004] However, in confined spaces, the conventional charging port hatch system may not open and close reliably, impairing the hatch's functionality. When the hatch is open, the charging plug may interfere with it, leading to reduced product quality or marketability.

[0005] Furthermore, the state-of-the-art charging port hatch system may have difficulties opening and closing the hatch in emergencies, e.g., if the battery is discharged and the actuator fails, making rapid battery charging difficult.

[0006] The background information described in this section is intended to provide context for understanding the background of the present disclosure and may contain technical information that is not part of the prior art, which is already publicly known, available or in use. OVERVIEW

[0007] The present disclosure relates to a loading port hatch system and in particular to a loading port hatch system designed for the automatic and / or manual opening and closing of a hatch under various conditions, thereby ensuring the reliable opening and closing of the hatch.

[0008] An embodiment of the present disclosure can solve the aforementioned problems of the prior art while retaining the advantages of the prior art.

[0009] An embodiment of the present disclosure can provide a charging port hatch system designed for automatic and / or manual opening and closing of a hatch under various conditions, thereby reliably performing the opening and closing of the hatch and preventing a charging plug from interfering with the hatch in a state where the hatch is open.

[0010] According to one embodiment of the present disclosure, a loading port hatch system may comprise: a housing; a hatch configured to rotate between a covering position, in which the hatch covers the housing, and a release position, in which the hatch releases the housing, and to move between a retracted position, in which the hatch comes into contact with the housing, and a forward position, in which the hatch is advanced out of the housing in a state where the hatch is in the covering position; a hatch actuator attached to the hatch, comprising an outer actuating element configured to be linearly moved and rotated by a motor, and an inner actuating element that is releasably engaged with the outer actuating element by a frictional closure; and a guide housing attached to the housing, configured to receive the outer actuating element.The outer actuating element can have a first guide groove extending linearly along its longitudinal direction and a second guide groove extending spirally from the first guide groove. The first and second guide grooves can be located on an outer surface of the outer actuating element. The guide housing can have a guide projection that engages in the first and second guide grooves.

[0011] The hatch actuator may also include a leadscrew rotated by the motor. The leadscrew may have an external thread on its outer circumferential surface, and the internal actuating element may have an internal thread that meshes with the external thread of the leadscrew.

[0012] The friction seal can be pressed between an outer surface of the inner actuating element and an inner surface of the outer actuating element. The friction seal can have a projection that is frictionally connected to the inner surface of the outer actuating element.

[0013] The friction closure can comprise a corrugated metal strip and a polymer layer attached to an outer surface of the metal strip. The polymer layer can be in frictional contact with the inner surface of the outer actuating element, and the metal strip can be in frictional contact with the outer surface of the inner actuating element.

[0014] The polymer layer can have a lower coefficient of friction than the metal strip.

[0015] The external actuating element may have a mounting section attached to the hatch.

[0016] The external actuator can be configured to move between a first position, a second position, and a third position. The hatch can be in the retracted position when the external actuator is in the first position, the hatch can be in the extended position when the external actuator is in the second position, and the hatch can be in the exposed position when the external actuator is in the third position.

[0017] When the external actuating element moves between the first position and the second position, the external actuating element can be guided linearly by the first guide groove and the guide projection, and when the external actuating element moves between the second position and the third position, the external actuating element can be guided by the second guide groove and the guide projection so that it rotates about its central axis.

[0018] The hatch actuator may further comprise an actuator housing that accommodates the motor and a guide sleeve extending from the actuator housing to the hatch. The guide sleeve may be received within the guide housing, and the external actuating element may be movably received within the guide sleeve.

[0019] The outer surface of the outer actuating element can be configured to align with an inner surface of the guide sleeve.

[0020] The guide housing can comprise a cylindrical section that accommodates the guide sleeve, a mounting plate provided on the cylindrical section, and a plurality of projections provided on the mounting plate. The multiple projections can be attached to the hatch by multiple fasteners.

[0021] The hatch actuator may also include a transmission mechanism designed to transfer torque from the motor to the leadscrew.

The external actuating element 17 can have a first end section facing the outside of the vehicle and a second end section facing the interior of the vehicle. According to one embodiment, the external actuating element 17 can be made of die-cast aluminum, which can improve the rigidity of the external actuating element 17.

[0038] Referring to Fig. 6. The external actuating element 17 can comprise a fastening section 15 that is integrally connected to the first end section thereof. The fastening section 15 can be made of the same material as the external actuating element 17, and the fastening section 15 and the external actuating element 17 can form a single, unified structure. The fastening section 15 of the external actuating element 17 can be attached to the hatch 12 by a fastening element. With reference to the Fig. 12, Fig. 14 and Fig. The fastening section 15 can be attached to the mounting section 12c of the inner plate 12b of the hatch 12. The fastening section 15 can comprise a fastening wall 15a, which is formed integrally with the first end section of the outer actuating element 17, and side walls 15b, which are connected to the edges of the fastening wall 15a. The fastening wall 15a can have a plurality of holes 15c, and a plurality of fastening elements (screws and the like) can each be screwed into the plurality of holes 15c such that the fastening wall 15a of the fastening section 15 can be attached to the mounting section 12c of the inner plate 12b of the hatch 12, and the side walls 15b of the fastening section 15 can comprise the side walls of the mounting section 12c of the inner plate 12b.Accordingly, the fastening section 15 of the outer actuating element 17 can be attached to the mounting section 12c of the inner plate 12b of the hatch 12 by means of the plurality of holes 15c. The outer actuating element 17 can be attached to the hatch 12 by the fastening section 15 so firmly that vibrations, shocks, damage and the like to the hatch 12 can be prevented while the hatch 12 is moving.

[0039] Referring to Fig. 7. The fastening section 15 can have a plurality of openings 15d, each opening 15d being arc-shaped and having an inner circumferential surface of each opening 15d aligned with an outer circumferential surface of the outer actuating element 17. The multiple openings 15d can be spaced apart from one another in a circumferential direction of the outer actuating element 17.

[0040] Referring to Fig. 6. The outer actuating element 17 can have a first guide groove 17a extending straight along the longitudinal axis of the outer actuating element 17, and a second guide groove 17b extending spirally from the first guide groove 17a. The first guide groove 17a can extend straight from the first end section of the outer actuating element 17 towards the second end section of the outer actuating element 17. The second guide groove 17b can extend spirally from the first guide groove 17a towards the second end section of the outer actuating element 17. The first guide groove 17a and the second guide groove 17b can be formed continuously in the outer circumferential surface of the outer actuating element 17. The outer actuating element 17 can comprise a first section X1, in which the first guide groove 17a is formed, and a second section X2, in which the second guide groove 17b is formed.The first section X1 and the second section X2 can be arranged along a longitudinal direction of the outer actuating element 17. The multiple first guide grooves 17a can be formed in the first section X1, the multiple second guide grooves 17b can each be connected to the multiple first guide grooves 17a, and the multiple second guide grooves 17b can be formed in the second section X2.

[0041] As in Fig. As shown in Figure 7, the inner actuating element 51 can be detachably connected to the cavity of the outer actuating element 17 by means of the friction lock 60. The inner actuating element 51 can have a first end section that points towards the outside of the vehicle and a second end section that points towards the interior of the vehicle. The friction lock 60 can be configured to connect and disconnect the outer actuating element 17 and the inner actuating element 51 by friction.

[0042] Referring to Fig. 12. The inner actuating element 51 can be a lead nut with an internal thread 51a formed therein, and the inner actuating element 51 can have a recessed section 52 provided in its first end section. The friction lock 60 can be fitted into the recessed section 52 of the inner actuating element 51, and the friction lock 60 can be pressed between an outer surface of the inner actuating element 51 and an inner surface of the outer actuating element 17 so that the inner actuating element 51 and the outer actuating element 17 can be engaged and disengaged by friction. The outer actuating element 17 and the inner actuating element 51 can be detachably connected to each other by the friction lock 60.

[0043] As in Fig. As shown in Figure 8, the hatch actuator 16 can comprise an actuator housing 21, a motor 25 that drives the inner actuating element 51, and a leadscrew 37 rotated by the motor 25. The motor 25 and the leadscrew 37 can be arranged within the actuator housing 21, and the inner actuating element 51 can be configured to move linearly by the rotation of the leadscrew 37. The motor 25 can be a bidirectional motor that rotates clockwise and counterclockwise. The leadscrew 37 can have an external thread 37a on an outer circumferential surface, and the leadscrew 37 can extend to a predetermined length. The leadscrew 37 can be configured to rotate about a central axis.

[0044] As in the Fig. 12, Fig. 14 and Fig. As shown in Figure 15, the internal thread 51a of the inner actuating element 51 can engage in the external thread 37a of the leadscrew 37. When the leadscrew 37 is rotated by the motor 25 and a transmission mechanism 30, the inner actuating element 51 can move in a longitudinal direction along the leadscrew 37. In a state where the outer actuating element 17 is connected to the inner actuating element 51 by the friction lock 60, the outer actuating element 17 can move together with the inner actuating element 51 in the same direction.

[0045] As in the Fig. 8 and Fig. As shown in Figure 9, the transmission mechanism 30 can be arranged between the motor 25 and the leadscrew 37. Referring to Fig. 8 The transmission mechanism 30 can be a gear train comprising an input gear 31 attached to an output shaft 25a of the motor 25, a first gear 32 meshing with the input gear 31, a second gear 33 attached to the first gear 32, a third gear 34 meshing with the second gear 33, and a fourth gear 35 attached to the third gear 34. Since the first gear 32 meshes with the input gear 31, torque from the motor 25 can be transmitted via the input gear 31 to the first gear 32, the second gear 33, the third gear 34, and the fourth gear 35. A gear pin 32a can be inserted into the center of the first gear 32 and the center of the second gear 33, and one end of the gear pin 32a can be rotatably mounted in a bushing 32b.A gear pin 35a can be inserted into the center of the third gear 34 and into the center of the fourth gear 35, and one end of the gear pin 35a can be rotatably mounted in a bushing 35b.

[0046] As in Fig. As shown in Figure 9, the axis of rotation of the input gear 31 can be aligned with the axis of rotation of the output shaft 25a of the motor 25. The axis of rotation of the first gear 32 can be perpendicular to the axis of rotation of the input gear 31. According to one embodiment, the input gear 31 and the first gear 32 can be a helical gear.

[0047] As in the Fig. 10 and Fig. As shown in Figure 11, the second gear 33 can be attached to the first gear 32 so that the second gear 33 can rotate in the same direction as the first gear 32. The axis of rotation of the second gear 33 can be aligned with the axis of rotation of the first gear 32. The diameter of the second gear 33 can be identical to or different from the diameter of the first gear 32.

[0048] As in the Fig. 10 and Fig. As shown in Figure 11, the axis of rotation of the third gear 34 can be parallel to the axis of rotation of the second gear 33. According to one embodiment, the second gear 33 and the third gear 34 can be a spur gear or a helical gear.

[0049] With reference to the Fig. 10 and Fig. 11. The fourth gear 35 can be attached to the third gear 34 in such a way that the fourth gear 35 can rotate together with the third gear 34 in the same direction. The axis of rotation of the fourth gear 35 can be aligned with the axis of rotation of the third gear 34. The diameter of the fourth gear 35 can be smaller than the diameter of the third gear 34.

[0050] As in Fig. As shown in Figure 9, the hatch actuator 16 can also include an operating gear 36 that transmits a torque from the transmission mechanism 30 to the leadscrew 37. The operating gear 36 can be attached to the leadscrew 37 such that the leadscrew 37 can rotate in the same direction as the operating gear 36. According to one embodiment, the operating gear 36 and the leadscrew 37 can form a single, integrated structure. Because the operating gear 36 and the leadscrew 37 form a single, integrated structure, vibrations, shocks, and the like between the operating gear 36 and the leadscrew 37 can be prevented. The operating gear 36 can be functionally connected to the transmission mechanism 30, and an axis of rotation of the operating gear 36 can be aligned with an axis of rotation of the leadscrew 37.In particular, the operating gear 36 can mesh with the fourth gear 35 of the gear mechanism 30, and the torque of the motor 25 can be transmitted by the gear mechanism 30 to the operating gear 36 in such a way that the operating gear 36 can rotate about its axis of rotation, and the leadscrew 37 can rotate together with the operating gear 36 in the same direction.

[0051] According to one embodiment, a central axis of the operating gear 36 can be perpendicular to a central axis of the fourth gear 35, the fourth gear 35 can be a worm gear, and the operating gear 36, which meshes with the fourth gear 35, can be a worm gear.

[0052] The second end section of the inner actuating element 51 can face the actuator housing 21 of the hatch actuator 16. With reference to the Fig. 12 and Fig. 14 The second end section of the inner actuating element 51 can move closer to or away from the operating gear 36 during the movement of the inner actuating element 51 by the rotation of the leadscrew 37.

[0053] As in Fig. As shown in Figure 8, a cover 23 can be connected to the actuator housing 21 by a plurality of snap fasteners, and the actuator housing 21 and the cover 23 can form a cavity. A seal 26 can be inserted between the edges of the actuator housing 21 and the edges of the cover 23, so that the actuator housing 21 and the cover 23 can be sealed by the seal 26. A printed circuit board (PCB) 24, the motor 25, the transmission mechanism 30, and the leadscrew 37 can be arranged in the cavity defined by the actuator housing 21 and the cover 23.

[0054] If a frictional force between the friction lock 60 and the outer actuating element 17 can be greater than an external force acting between the friction lock 60 and the outer actuating element 17, the friction lock 60 can allow the outer actuating element 17 and the inner actuating element 51 to be frictionally connected. If the frictional force between the friction lock 60 and the outer actuating element 17 is less than the external force acting between the friction lock 60 and the outer actuating element 17, the friction lock 60 can allow the outer actuating element 17 and the inner actuating element 51 to be frictionally separated (or allow relative movement between the inner actuating element 51 and the outer actuating element 17). Referring to Fig. The friction closure 60 can have a plurality of projections 61 extending in the direction of its outer diameter, and the plurality of projections 61 can be spaced apart from one another at a predetermined distance in a circumferential direction. An inner surface of the friction closure 60 can engage frictionally with the outer surface of the inner actuating element 51, and the plurality of projections 61 can engage frictionally with the inner surface of the outer actuating element 17. The friction closure 60 can comprise a corrugated metal strip 62 and a polymer layer 63 attached to an outer surface of the metal strip 62. The metal strip 62 can be in frictional contact with the outer surface of the inner actuating element 51, and the polymer layer 63 can be in frictional contact with the inner surface of the outer actuating element 17. The polymer layer 63 can have a lower coefficient of friction than the metal strip 62.The metal strip 62 can be made of stainless steel, and the polymer layer 63 can be made of polytetrafluoroethylene (PTFE).

[0055] The torque of the motor 25 can be adjusted so that it is less than the frictional force between the projections 61 of the friction fastener 60 and the inner surface of the outer actuating element 17, and accordingly, the inner surface of the outer actuating element 17 and the outer surface of the inner actuating element 51 can be held in engagement by the frictional force of the friction fastener 60. Since the torque of the motor 25 is transmitted to the input gear 31, the first gear 32, the second gear 33, the third gear 34, the fourth gear 35, the operating gear 36, and the leadscrew 37, the leadscrew 37 can rotate, the inner actuating element 51 can move longitudinally along the leadscrew 37 by the rotation of the leadscrew 37, and the outer actuating element 17 can move in the same direction together with the inner actuating element 51.

[0056] If the hatch 12 cannot be opened and closed electrically due to a discharged battery, a failure of the hatch actuator 16, or the like, the user can open and close the hatch 12 manually. When the user opens or closes the hatch 12 manually, an external force exerted on the hatch 12 by the user can be transmitted to the outer actuator 17, and the outer actuator 17 can move and rotate linearly with the hatch 12. If the external force transmitted from the outer actuator 17 to the inner actuator 51 is greater than the frictional force between the projections 61 of the friction lock 60 and the inner surface of the outer actuator 17, slippage can occur between the projections 61 of the friction lock 60 and the outer actuator 17.Since the inner surface of the outer actuating element 17 is detached from the outer surface of the inner actuating element 51, the outer actuating element 17 can move relative to the inner actuating element 51, the inner actuating element 51 and the operating gear 36 cannot move, and the motor 25 and the transmission mechanism 30 cannot operate. If the user opens or closes the hatch 12 manually, the external force exerted on the outer actuating element 17 cannot be transmitted to the inner actuating element 51, the transmission mechanism 30, and the motor 25 in such a way as to prevent the transmission of an overload to the motor 25.

[0057] As in Fig. As shown in Figure 12, the hatch actuator 16 can include a guide sleeve 22 extending a predetermined length from the actuator housing 21. The guide sleeve 22 can have a first end section facing the outside of the vehicle and a second end section facing the inside of the vehicle. The first end section of the guide sleeve 22 can face the hatch 12, and the second end section of the guide sleeve 22 can be integrally connected to the actuator housing 21. With reference to the Fig. 12, Fig. 14 and Fig. 15. The guide sleeve 22 can extend from the actuator housing 21 towards the hatch 12. The outer actuating element 17 and the inner actuating element 51 can be movably received in the guide sleeve 22, and the guide sleeve 22 can be configured to guide the linear movement and rotation of the outer actuating element 17 and the inner actuating element 51. The outer actuating element 17 can have a cylindrical shape with a predetermined outer diameter, and the guide sleeve 22 can have a cylindrical shape with an inner diameter that corresponds to the outer diameter of the outer actuating element 17. Since the outer diameter of the outer actuating element 17 is slightly less than or equal to the inner diameter of the guide sleeve 22, the outer surface of the outer actuating element 17 can correspond to an inner surface of the guide sleeve 22.Accordingly, vibrations, shocks and the like can be prevented while the outer actuating element 17 moves and rotates in the guide sleeve 22.

[0058] According to an embodiment of the present disclosure, the outer actuating element 17 and the inner actuating element 51 can be assembled with the leadscrew 37, and then the outer actuating element 17, the inner actuating element 51 and the leadscrew 37 can be assembled with the actuator housing 21, since the actuating gear 36 can be attached to the leadscrew 37. Afterwards, the mounting section 15 of the outer actuating element 17 can be attached to the inner plate 12b of the hatch 12.As described above, the outer actuating element 17, the inner actuating element 51 and the leadscrew 37 can be pre-assembled, and the outer actuating element 17, the inner actuating element 51 and the leadscrew 37 can be assembled with the actuator housing 21, and then the outer actuating element 17 can be assembled with the hatch 12 in such a way that the assembly process is not only simplified, but can also be carried out smoothly and stably.

[0059] The charging port hatch system 10 according to an embodiment of the present disclosure can comprise a guide housing 40 configured to receive the guide sleeve 22 and the external actuating element 17. The guide housing 40 can extend through an opening in the housing 11, and the guide housing 40 can be attached to the housing 11. The guide housing 40 can have a first end section that points to the outside of the vehicle and a second end section that points to the interior of the vehicle.The external actuating element 17 can be received in the guide sleeve 22 of the hatch actuator 16, the guide sleeve 22 can be received in the guide housing 40, and the guide housing 40 can be attached to the housing 11 in such a way that the support stiffness of the external actuating element 17 and the hatch 12 can be improved, and accordingly the hatch 12 can be stably supported against various adverse conditions and external vibrations.

[0060] As in Fig. As shown in Figure 5, the guide housing 40 can comprise a cylindrical section 41, a mounting plate 42 provided on the cylindrical section 41 and a plurality of projections 43 provided on the mounting plate 42.

[0061] The cylindrical section 41 can have a first end section pointing towards the outside of the vehicle and a second end section pointing towards the inside of the vehicle. The cylindrical section 41 can extend through the opening of the housing 11, and the cylindrical section 41 can be configured to receive the guide sleeve 22 of the hatch actuator 16. If the guide sleeve 22 of the actuator housing 21 is received in the cylindrical section 41 of the guide housing 40, the outer actuating element 17 and the inner actuating element 51 can move and rotate through the guide sleeve 22 and the guide housing 40.

[0062] The mounting plate 42 can be attached to the inner surface of the housing 11 by means of the multitude of projections 43.

[0063] The multiple projections 43 can be provided on the edges of the mounting plate 42, and the multiple projections 43 can extend from the mounting plate 42 into the interior of the vehicle. A fastening element, e.g., a screw, can be screwed into each projection 43 such that the mounting plate 42 of the guide housing 40 can be attached to the inner surface of the housing 11. The mounting plate 42 of the guide housing 40 can be firmly connected to the housing 11 by the multiple projections 43 in such a way that vibrations, shocks, damage, and the like to the actuating elements can be prevented while the outer actuating element 17 and the inner actuating element 51 are moving.

[0064] With reference to the Fig. 5, Fig. 7 and Fig. 13 The guide housing 40 can have guide projections 47 on its inner surface, and each guide projection 47 can extend from an inner surface of the cylindrical part 41 towards the center of the cylindrical part 41. The guide projection 47 can be received in the first guide groove 17a and the second guide groove 17b of the outer actuating element 17. Accordingly, the linear movement and rotation of the outer actuating element 17 can be guided by the guide projections 47 and the guide grooves 17a and 17b. According to one embodiment, the guide projections 47 can be provided at the first end section of the cylindrical section 41 of the guide housing 40, and accordingly, the guide projections 47 and the guide grooves 17a and 17b can guide the linear movement and rotation of the outer actuating element 17 over the entire length of the outer actuating element 17.

[0065] Referring to Fig. 5. The guide housing 40 can have a plurality of support projections 44 extending from the first end section of the cylindrical section 41 towards the outside of the vehicle. Each support projection 44 can be arc-shaped, and the multiple support projections 44 can be spaced apart from one another in the circumferential direction of the cylindrical section 41. As shown in Fig. As shown in Figure 7, the support projections 44 of the guide housing 40 can be inserted into or removed from the openings 15d of the fastening section 15 of the outer actuating element 17.

[0066] Referring to Fig. 14. In a state where the outer actuating element 17 engages with the inner actuating element 51 via the friction lock 60, the inner actuating element 51 can move in the longitudinal direction of the leadscrew 37 by rotating the leadscrew 37 such that the outer actuating element 17 can move together with the inner actuating element 51 in the same direction. While the outer actuating element 17 moves due to the rotation of the leadscrew 37 and the linear movement of the inner actuating element 51, the first guide groove 17a of the outer actuating element 17 can be guided by the guide projection 47 of the guide housing 40 such that the outer actuating element 17 can move linearly along the first guide groove 17a.This means that when the leadscrew 37 is rotated and the outer actuating element 17 is guided through the first guide groove 17a and the guide projection 47, the outer actuating element 17 can move forward or backward in the longitudinal direction of the leadscrew 37.

[0067] Referring to Fig. 15. In a state where the outer actuating element 17 is engaged with the inner actuating element 51 by means of the friction fastening 60, the inner actuating element 51 can move longitudinally along the leadscrew 37 by the rotation of the leadscrew 37 such that the outer actuating element 17 can move together with the inner actuating element 51. While the outer actuating element 17 moves due to the rotation of the leadscrew 37 and the linear movement of the inner actuating element 51, the outer actuating element 17 can be guided by the second guide groove 17b and the guide projection 47 such that the outer actuating element 17 can move (rotate) helically along the second guide groove 17b. Since the rotation of the outer actuating element 17 is guided by the second guide groove 17b and the guide projection 47, the outer actuating element 17 can rotate about its central axis.

[0068] In a state where the outer actuating element 17 is engaged with the inner actuating element 51 by means of the friction lock 60, the outer actuating element 17 and the inner actuating element can be arranged to move between a first position (see P1 of Fig. 12), a second position (see P2 of Fig. 14) and a third position (see P3 of Fig. 15) to move. In a state where the outer actuating element 17 engages with the inner actuating element 51 via the friction lock 60, the outer actuating element 17 can be guided linearly by the guide projection 47 and the first guide groove 17a when the outer actuating element 17 and the inner actuating element 51 move between the first position P1 and the second position P2. In a state where the outer actuating element 17 engages with the inner actuating element 51 via the friction lock 60, when the outer actuating element 17 and the inner actuating element 51 move between the second position P2 and the third position P3, the outer actuating element 17 can be guided by the guide projection 47 and the second guide groove 17b such that it rotates about its central axis.

[0069] Referring to Fig. 6. The outer actuating element 17 may include a stop 18 designed to limit the movement of the outer actuating element 17. The stop 18 may be attached to the second end section of the outer actuating element 17 and may have an annular recessed section 18a provided in an outer circumferential surface thereof. When the outer actuating element 17 moves into the third position, the stop 18 may prevent the outer actuating element 17 from being released from the guide sleeve 22 and the guide housing 40. When the outer actuating element 17 moves forward into the third position, the stop 18 may be stopped by the guide projection 47 to prevent the outer actuating element 17 from being released from the guide sleeve 22.

[0070] As in Fig. As shown in Figure 8, the hatch actuator 16 can also include a sensor 39 configured to detect the position of the hatch 12. The hatch actuator 16 can have a sensor receiving section 22a that is integrally connected to the guide sleeve 22. With reference to the Fig. 12, Fig. 14 and Fig. 15. The sensor 39 can extend in a longitudinal direction along the guide sleeve 22 and be received in the sensor receiving section 22a. The sensor 39 can detect the position of the external actuating element 17 in order to determine the position of the hatch 12. Referring to Fig. 5. The guide housing 40 can have a cover section 45 that is integrally connected to the cylindrical section 41, and the cover section 45 can extend in a longitudinal direction of the cylindrical section 41. Referring to Fig. 12. The cover section 45 can cover the sensor receiving section 22a.

[0071] With reference to the Fig. 12, Fig. 14 and Fig. 15. The sensor 39 can have a tip 39a that is movable in the longitudinal direction. A free end of the tip 39a can be fitted into the recessed section 18a of the stop 18 such that the tip 39a can be connected to the stop 18. If the outer actuating element 17 moves and rotates, the tip 39a of the sensor 39 can move together with the outer actuating element 17. The sensor 39 can be configured to detect whether the stop 18 of the outer actuating element 17 is in the first position P1, the second position P2, or the third position P3. A control unit (not shown) can be configured to accurately detect the position of the hatch 12 based on the position of the outer actuating element 17 detected by the sensor 39.

[0072] If the outer actuating element 17 is in the first position P1, the hatch 12 can be in the covered position and the retracted position such that the hatch 12 can be completely closed to cover the housing 11 (see Fig. 12, Fig. 16 and Fig. 17). With reference to the Fig. 14 and Fig. 18. The hatch 12 can be in the covered position and the advanced position when the external actuating element 17 is in the second position P2, so that the hatch 12 can move forward from the housing 11 towards the outside of the vehicle, and accordingly, the hatch 12 can be spaced away from the housing 11. With reference to the Fig. 15, Fig. 19 and Fig. 20 The hatch 12 can be in the exposure position to expose the housing 11 when the external actuating element 17 is in the third position P3, and accordingly the hatch 12 can be opened.

[0073] When the motor 25 rotates, its torque can be transmitted via the transmission mechanism 30 to the operating gear 36 and the leadscrew 37. When the operating gear 36 and the leadscrew 37 rotate, the inner actuating element 51 and the outer actuating element 17 can move longitudinally along the leadscrew 37.

[0074] When the outer actuating element 17 is in the first position P1, the second end section of the outer actuating element 17 can move close to the actuator housing 21, and the first end section of the outer actuating element 17 can align with the first end section of the guide sleeve 22 of the actuator housing 21. When the outer actuating element 17 is in the first position P1, the entire edge of the hatch 12 can contact the seal 13 of the housing 11 as shown in the Fig. 16 and Fig. Figure 17 shows that the hatch 12 and the housing 11 can be sealed and the hatch 12 can be completely closed to cover the housing 11.

[0075] When the user presses the hatch 12 in a closed position, the hatch 12 can press the opening button 14b, and the actuating gear 36 and the leadscrew 37 can rotate in a first direction through the motor 25 and the transmission mechanism 30 such that the inner actuating element 51 and the outer actuating element 17 can move forward in the longitudinal direction of the leadscrew 37 towards the outside of the vehicle (see the direction of arrow K in Fig. 14) If the inner actuating element 51 and the outer actuating element 17 move forward by the rotation of the leadscrew 37, the first guide groove 17a of the outer actuating element 17 can be guided linearly through the guide projection 47 of the guide housing 40 such that the inner actuating element 51 and the outer actuating element 17 can move linearly along the first guide groove 17a towards the outside of the vehicle, and accordingly, the inner actuating element 51 and the outer actuating element 17 can be in the second position P2. If the outer actuating element 17 is in the second position P2, the second end section of the outer actuating element 17 can move forward from the actuator housing 21, and the first end section of the outer actuating element 17 can move forward from the first end section of the guide sleeve 22 of the actuator housing 21 towards the outside of the vehicle.If the hatch 12 moves forward together with the outer actuating element 17, the hatch 12 can be advanced from the housing 11 towards the outside of the vehicle by a predetermined distance. If the outer actuating element 17 is in the second position P2, the hatch 12 can be advanced from the housing 11 towards the outside of the vehicle, as shown in Figure 1. Fig. 18 shown, and the entire edge of the hatch 12 can be spaced apart from the seal 13 of the housing 11 by a predetermined distance S.

[0076] Referring to Fig. 15. The inner actuating element 51 and the outer actuating element 17 can move from the second position P2 towards the third position P3 by rotating the leadscrew 37, provided that the operating gear 36 and the leadscrew 37 rotate continuously in the first direction by the motor 25 and the transmission mechanism 30. When the outer actuating element 17 moves from the second position P2 to the third position P3, the second guide groove 17b of the outer actuating element 17 can be guided by the guide projection 47 of the guide housing 40 such that the outer actuating element 17 can move spirally forward along the second guide groove 17b towards the outside of the vehicle.Accordingly, the outer actuating element 17 can rotate about its central axis (see arrow direction R in . Fig. 15 and Fig. 20). As in Fig. As shown in Figure 20, hatch 12 can be opened when it rotates into the exposure position.

[0077] If the outer actuating element 17 is in the first position, the support projections 44 of the guide housing 40 can be inserted into the openings 15d of the fastening section 15 (see Fig. 12). In a closed position, the hatch 12 can be held stably by the support projections 44 of the guide housing 40 and the openings 15d of the mounting section 15. When the external actuating element 17 is in the second and third positions, the support projections 44 of the guide housing 40 can be released from the openings 15d of the mounting section 15, and accordingly, the hatch 12 can be opened stably (see Figure 12). Fig. 14 and Fig. 15).

[0078] As in the Fig. 19 and Fig. As shown in Figure 20, when the user presses the closing button 14c while the hatch 12 is open, the actuating gear 36 and the leadscrew 37 can rotate in a second direction opposite to the first direction via the motor 25 and the transmission mechanism 30, and the inner actuating element 51 and the outer actuating element 17 can move from the third position to the second position. As the outer actuating element 17 moves from the third position to the second position, the second guide groove 17b of the outer actuating element 17 can be guided by the guide projection 47 of the guide housing 40 such that the outer actuating element 17 can move backward in a spiral motion along the second guide groove 17b towards the second position. Accordingly, the outer actuating element 17 can rotate about its central axis (see the direction opposite to the direction of arrow R in Figure 20). Fig.15), and the hatch 12 can rotate into the cover position. Since the actuating gear 36 and the leadscrew 37 rotate continuously in the second direction by the motor 25 and the transmission mechanism 30 in a state where the inner actuating element 51 and the outer actuating element 17 are in the second position, the inner actuating element 51 and the outer actuating element 17 can move from the second position towards the first position by the rotation of the leadscrew 37. If the outer actuating element 17 moves from the second position to the first position, the first guide groove 17a of the outer actuating element 17 can be guided continuously by the guide projection 47 of the guide housing 40 such that the outer actuating element 17 can move from the second position to the first position.When the outer actuating element 17 moves from the second position to the first position, it can be guided linearly into the first position by the guide projection 47 and the first guide groove 17a. When the hatch 12 moves into the retracted position, the hatch 12 can come into contact with the seal 13 of the housing 11, and the hatch 12 can be completely closed.

[0079] As explained above, the charging port hatch system, according to the embodiments of this disclosure, can be configured such that the hatch can be moved by the hatch actuator between the covered position, in which the hatch covers the housing, and the exposed position, in which the hatch exposes the housing. In the covered position, the hatch can be configured to move between the retracted position, in which the hatch comes into contact with the housing, and the extended (protruded) position, in which the hatch is extended from the housing, such that opening and closing of the hatch can occur smoothly in a confined space. Furthermore, in a state where the hatch is open, the system can prevent the charging plug from obstructing the hatch.

[0080] If the frictional force between the friction lock and the outer actuating element is greater than the external force acting between the friction lock and the outer actuating element, the friction lock can allow the outer and inner actuating elements to be frictionally connected. Accordingly, the outer actuating element can move in the same direction as the inner actuating element when the leadscrew is rotated by the hatch actuator motor.

[0081] If the frictional force between the friction lock and the external actuator is less than the external force acting between the friction lock and the external actuator, the friction lock can allow the external and internal actuators to separate by friction. Consequently, the external actuator can move along with the hatch, and the hatch can be opened and closed manually.
