DETAILED DESCRIPTION

[0018] The following is further illustrated in combination with the drawings and examples.

[0019] Figures 1-3 As shown: a rotating telescopic opening and closing charging port cover device comprises a cover plate 1, a connecting seat 2, a connecting sleeve 3, a cover plate support seat 5, a shaft sleeve 7, an installation box 9, a motor 10, a worm 11, a worm wheel 12, a rack 14, a telescopic driving sleeve 15, a check ring 18, a rotating driving sleeve 20 and a telescopic guide rod 25.

[0020] In this embodiment, the inner side of the cover plate 1 is connected to the connecting seat 2, and the connecting seat 2 faces inward to form the connecting sleeve 3. The connecting sleeve 3 is axially connected to the telescopic guide rod 25 by a screw, and the inner wall of the connecting sleeve 3 is provided with a clamp 4. The outer end of the telescopic guide rod 25 is fitted with a rotary drive sleeve 20 to form the cover plate drive rod 19. The cover plate drive rod 19 is inserted into the bushing 7 in the drive hole 6 of the cover plate support 5. Two drive columns 8 are symmetrically distributed in the same circumferential cross section inside the bushing 7. The outer end of the rotary drive sleeve 20 is provided with a clamp 21 corresponding to the clamp 4. The outer wall of the rotary drive sleeve 20 is symmetrically provided with two drive grooves 22 corresponding to the drive columns 8. The drive grooves include an axially connected linear drive groove 23 and a helical drive groove 24 from the outside to the inside. The inner end of the telescopic guide rod 25 is fitted with a telescopic drive sleeve 15.

[0021] The cover plate support 5 is connected inward to the mounting box 9. The mounting box 9 contains a motor 10, a worm gear 11, a spur gear 12, and a drive gear 13. The motor 10 is connected to the worm gear 11, and the worm gear 11 drives the spur gear 12. The spur gear 12 meshes with the rack 14 on the outer wall of the telescopic drive sleeve 15. The telescopic drive sleeve 15 is provided with an axial guide groove 16. The mounting box 9 passes through the telescopic drive sleeve 15 and is provided with a limiting head. The limiting head guides the corresponding guide groove 16. The outer axial end of the telescopic drive sleeve 15 abuts against the inner axial end of the rotary drive sleeve 20. The inner end of the telescopic drive sleeve 15 is connected to the telescopic guide rod 25 for limiting via a retaining ring 18.

[0022] During opening and closing operations, the motor 10, via the worm gear 11 and spur gear 12 meshing with the rack 14, pushes the telescopic drive sleeve 15, constrained by the limiting head and guide groove 16, axially and linearly outward along the telescopic guide rod 25 to push the rotary drive sleeve 20. Simultaneously, the telescopic guide rod 25 pushes the cover plate 1 outward via the connecting seat 2. As the rotary drive sleeve 20 moves axially outward, it moves forward linearly via the drive groove 22, constrained by the drive column 8, and rotates via the drive groove 23 and the helical drive groove 24. The slot 21 of the rotary drive sleeve 20 engages with the locking head 4 of the connecting sleeve 3, and the connecting seat 2 drives the cover plate 1 to rotate, thus realizing the extension and rotation opening of the cover plate 1. Conversely, when the telescopic drive sleeve 15 retracts, the rotary drive sleeve 20 drives the telescopic guide rod 25 to retract after rotating in the opposite direction, realizing the rotation and retraction closing of the cover plate 1.

[0023] In this embodiment, the linear drive groove 23 extends directly to the outer end face of the rotary drive sleeve 20. Based on this, the position of the bayonet 21 can utilize or enlarge the linear drive groove at the end.

[0024] Based on this embodiment, the inner wall of the bushing can be provided with multiple drive posts that are respectively inserted into the drive groove for guidance. The multiple drive posts are evenly distributed around the circumference on the same circumferential section, and the drive grooves that cooperate with the drive posts are evenly distributed around the circumference on the same circumference; or the multiple drive posts are evenly distributed around the circumference but not on the same circumferential section, and the drive grooves that cooperate with the drive posts are not evenly distributed around the circumference on the same circumference in the axial direction.
