[0059] Further, an anti-loosening gear ring 224 is arranged inside the bolt sleeve 221. The anti-loosening gear ring 224 is made of an elastic material to have elasticity, and the inner side of the anti-loosening gear ring 224 cooperates with the outer side of the bolt body 2221. Specifically, the anti-loosening gear ring 224 has an annular gear ring base 2241, and the outer diameter of the gear ring base 2241 matches the inner diameter of the bolt sleeve 221. Among them, a plurality of axially extending gear ring portions 2242 are arranged at intervals along the gear ring base 2241. Here, the gear ring portions 2242 are axially extended and arranged along the inner surface of the bolt sleeve 221. Among them, the plurality of gear ring portions 2242 are evenly arranged relative to the gear ring base 2241.

[0060] Further, the end of the gear ring portion 2242 has an anti-loosening protrusion 22421. The anti-loosening protrusion 22421 abuts against the inner side of the upper surface of the bolt sleeve 221 and cooperates with the anti-loosening gear disc 2222. A second tooth structure 22421a is arranged on the surface of the anti-loosening protrusion 22421, that is, the surface facing the bolt body 2221, and the second tooth structure 22421a is arranged in cooperation with the first tooth structure 2222a.

[0061] Further, a limiting groove 22422 is arranged on the gear ring portion 2242, and the limiting groove 22422 can be clamped with the bolt tightening sleeve 223. A tooth disc traveling section is arranged between the anti-loosening protrusion 22421 and the limiting groove 22422 on the gear ring portion 2242, and the anti-loosening gear disc 2222 moves within the tooth disc traveling section.

[0062] Further, the bolt tightening sleeve 223 includes a tightening sleeve base 2231. A tightening sleeve 2232 is arranged on the tightening sleeve base 2231. The tightening sleeve base 2231 is in contact with the anti-loosening gear disc 2222. The inner side of the tightening sleeve 2232 is polygonal, for example, quadrilateral, so as to be matched with the second section of the bolt body 2221, thereby facilitating the movement of the tightening sleeve 2231 along the second section. Among them, a third tooth structure 2233 is arranged on the outer surface of the tightening sleeve 2232.

[0063] To achieve the limitation of the bolt tightening sleeve 223, the limiting groove 22422 herein has a first groove wall 22422a and a second groove wall 22422b arranged oppositely, wherein the first groove wall 22422a is perpendicular to the moving direction of the bolt tightening sleeve 223, and the second groove wall 22422b is inclined relative to the first groove wall 22422a. When the bolt tightening sleeve 223 is fixed through the limiting groove 22422, the tightening sleeve base 2231 is embedded into the limiting groove 22422, its lower surface is in contact with the first groove wall 22422a, and its upper surface abuts against the second groove wall 22422b.

[0064] Further, the bolt tightening sleeve 223 is connected to the power exchange connection part 3, wherein the power exchange connection part 3 includes a connection part main body 31, a first accommodation groove 32 is arranged at a first end of the connection part main body 31, and a second section of the bolt main body 2221 can extend into and be accommodated in the first accommodation groove 32.

[0065] Specifically, the tightening sleeve 2232 of the bolt tightening sleeve 223 is connected to the power exchange connection part 3, wherein a fourth tooth structure 321 is arranged on the inner side of the notch of the first accommodation groove 32, and the fourth tooth structure 321 is engaged with the third tooth structure 2233 on the outer surface of the tightening sleeve 2232, so as to drive the power exchange connection part 3 to move when the bolt tightening sleeve 223 moves.

[0066] Further, an elastic member 323 is arranged at the bottom of the first accommodation groove 32, and a groove 2224 is arranged at the end of the second section of the bolt main body 2221. After the bolt main body 2221 extends into the first accommodation groove 32, the elastic member 323 abuts against the bottom of the groove 2224.

[0067] Further, a second accommodation groove 33 is also arranged at a second end of the connection part main body 31. The cross section of the second accommodation groove 33 herein is polygonal, for example, it can be quadrilateral. The connection with the power exchange device of the vehicle is achieved through the second accommodation groove 33.

[0068] When moving the power swapping connection part 3 towards the nut sleeve assembly 21, the bolt body 2221 is driven to move towards the nut sleeve assembly 21. Meanwhile, under the action of the elastic member 323, the bolt tightening sleeve 223 is fixed in the limiting groove 22422. As the anti-loosening tooth disc 2222 gradually moves to the top, due to the action of the axial force, the tightening sleeve base 2231 presses against the second groove wall 22422b, and the anti-loosening protrusion 22421 moves radially away from the bolt body 2221 under the action of elasticity, so that the upper surface of the anti-loosening tooth disc 2222 can be attached to the inner surface of the top of the bolt sleeve 221. Then, the bolt tightening sleeve 223 is released so that the tightening sleeve base 2231 no longer presses against the second groove wall 22422b, thereby enabling the second tooth structure 22421a to be engaged with the first tooth structure 2222a on the anti-loosening tooth disc 2222, thus realizing the locking between the locking bolt 222 and the anti-loosening tooth ring 224 to prevent the bolt body 2221 from rotating continuously.

[0069] The embodiments of the present disclosure facilitate the tight connection between the power swapping device and the vehicle, and can achieve locking after connection to prevent loosening, ensuring the connection stability of the power swapping device and having high safety at the same time.
