As shown in fig. 5-6, the present embodiment discloses a quick-

100, which includes at least two

1 arranged along the width direction of a

200, each

1 is provided with a plurality of locking

11 at least on two opposite sides, and the locking

11 are configured to cooperate with locking

21 on the

200 in a bolt locking manner to lock the battery packs 1.

By arranging the plurality of battery packs 1, the problem that battery replacement is difficult due to overlarge volume and weight of a

1 is avoided, the bearing requirements on the locking

11 are reduced, and the firmness and stability of connection between the battery pack and a battery replacement vehicle are improved by arranging the plurality of locking

11 on each

1; the plurality of

1 are arranged along the width direction of the

200, the structural arrangement is compact, the battery packs 1 can be arranged by utilizing the spaces between the longitudinal beams 3 of the vehicle body and the spaces at two sides, and the installation space is saved; on the other hand, when one of the battery packs 1 is damaged, the

1 ensure the normal operation of the

200; the arrangement of a plurality of battery packs 1 is also beneficial to standardization of the battery packs. In addition, the bolt locking mode is simple and reliable, so that the

1. Preferably, the nut is floatingly coupled to the

1, or the

41 is floatingly coupled to the charging

200.

As shown in fig. 1-4, the locking

11 includes a

41, a

42, an

43, an

44, an

45, and a connecting

46, wherein both ends of the

41 are respectively provided with a threaded

411 and a

412, and the threaded

411 on the

41 is used for being in threaded connection with a nut; the

412 on the

461 on the connecting

46 to limit the rotation of the

41 by limiting the rotation of the connecting

46; the threaded

411 is disposed on the top of the

41, so that the

412 is disposed on the other end of the

41 to connect with other components, thereby making the structure compact. The flange 463 of the connecting portion 46 is fitted into the outer flange 452 of the outer ring gear 45, and the outer vertical groove 462 of the connecting portion 46 is engaged with the inner peripheral surface of the outer ring gear 45, so that the connecting portion 46 and the outer ring gear 45 are formed integrally; the external teeth 451 of the external gear ring 45 are engaged with the internal teeth 441 of the internal gear ring 44, the rotation of the external gear ring 45, the connecting part 46 and the bolt 41 is limited by limiting the rotation of the internal gear ring 44, and the internal gear ring 44, the external gear ring 45 and the connecting part 46 form an anti-rotation and anti-backing structure for limiting the relative rotation of the bolt 41 and the nut; the inner flange 442 of the inner gear ring 44 is used for abutting with the outer flange 452 of the outer gear ring 45 for axis limitation; one end of the spring 42 is used for abutting against one end of the inner part of the shell 43 close to the threaded section 411, and the other end of the spring 42 is used for abutting against one end of the whole of the outer gear ring 45 and the connecting part 46 close to the threaded section 411; the housing 43 is used for being sleeved outside the bolt 41, the spring 42, the outer gear ring 45, the inner gear ring 44 and the connecting part 46.

41 sets up in

43, to its guard action of

41, dustproof and waterproof, can also avoid

41 directly to receive external force striking simultaneously and lead to the locking to warp or drive the connection structure of nut and nut to receive the impact. The

41 can be lifted or rotated in a vertical direction relative to the

43, and the

43 restricts the moving direction of the

41, so that the

41 can perform a rotational movement relative to the nut to lock and unlock. When the

1 moves in the vertical direction to be mounted or dismounted, the

41 is lifted in the vertical direction, so that the movement process of the

1 is combined with the vertical locking process of the

21 and the

11, and the locking efficiency is improved. Meanwhile, the

41 goes up and down along the vertical direction, so that the interference between the

41 and parts in the horizontal direction during movement can be avoided, and the structure is compact.

200 to lock the

1, the nut of the

21 is fixed to the

200, and the

44 is fixed to the

1 to connect the

41 to the

1.

During unlocking, a professional tool is used for pushing the whole of the

45 and the connecting

46, the whole of the

45 and the connecting

46 moves away from the

44, so that the

45 is disengaged from the

44, the

41 is driven to rotate relative to the nut by rotating the whole of the

45 and the connecting

46 until the

41 is disengaged from the nut, unlocking of the

1 and the

200 is achieved, and the

42 drives the

45, the connecting

46 and the

41 to retreat.

When locking is carried out, a professional tool is used for pushing the whole of the

45 and the connecting

46, so that the whole of the

45 and the connecting

46 moves in the direction away from the

44, the

45 and the

44 are separated, and then the whole of the

45 and the connecting

46 is rotated to drive the

41 to rotate relative to the nut until the locking torque of the

41 and the nut is met, so that the

41 and the nut are locked; when the tool is removed, the

42 drives the

45, the connecting

46 and the

41 to retract, so that the

45 is engaged with the

44, and the

452 of the

45 abuts against the

442 of the

44 to limit the rotation and the axial movement of the

41; if the

45 cannot engage the

44, the

45 can be rotated slightly to engage the

44.

In the embodiment, the

44 is fixed on the battery pack, and the rotation of the

41 is limited by the rotation-preventing and retaining structure consisting of the

44, the

45 and the connecting

46. In the locked state, the

44 and the

45 are engaged to restrict rotation of the

41 relative to the nut, and the

442 of the

44 serves to restrict movement of the

452 of the

45, never restricting movement of the

41 relative to the nut. In other embodiments, the structure of the anti-rotation backstop structure may be different from that of the present embodiment. In other embodiments, a toothed member may be inserted into the

412 of the

41 and secured to the battery pack, or to the vehicle to limit rotation of the

41 relative to the nut, and then removed when unlocked. In other embodiments, a screw may be used instead of the toothed member, and the screw may be used to tighten the threaded

411 of the

41 to prevent the

41 from rotating. In other embodiments, a structure capable of preventing relative rotation between the

41 and the nut in the prior art may be adopted as the rotation-preventing and backing-stopping structure.
