Specifically, as shown in fig. 4, the anti-loosening portion in this embodiment is specifically a nut sleeve 26, the driving portion is a nut 25, the nut 25 is in threaded connection with one end of the shaft body 211, which is far away from the hanging portion 212, the nut sleeve 26 is installed on the nut 25, so as to fix the nut 25 and the battery pack 1, ensure that the nut 25 does not rotate and fall off before the battery pack 1 is installed, ensure that the shaft body 211 cannot rotate through the nut 25, and further ensure that the hanging portion 212 does not rotate.

In other alternative embodiments, the anti-loosening portion may also limit the rotation of the hanging portion 212 relative to the lock base 3131 by one of the engagement modes of ratchet, pawl, bead, snap and engagement. Wherein, the structures of the anti-loosening parts in different locking devices can be the same or different.

As shown in fig. 4, 5, 6 and 9, the locking member 200 further includes a base 22, and the t-shaped locking lever 21 is disposed in the base 22 and can be vertically lifted or rotated with respect to the base 22. The base 22 can limit the moving direction of the T-shaped lock lever 21, prevent the T-shaped lock lever 21 from deviating during moving, and improve the reliability of the locking and unlocking processes. Through the lifting or rotating of the T-shaped lock rod phase 21 relative to the base 22 along the vertical direction, the position of the T-shaped lock rod phase 21 relative to the base 22 in the vertical direction can be adjusted, and therefore the battery pack can be locked and fixed and unlocked relative to the battery replacing vehicle. Specifically, the base 22 is a cylindrical structure having a through hole for the T-shaped lock lever 21 to pass therethrough.

In this embodiment, the T-shaped lock lever 21 is further provided with a driving portion, and the driving portion is used for driving the hanging portion 212 to lift or rotate along the vertical direction under the action of the external driving mechanism. The driving portion is arranged to facilitate the hanging portion 212 to lift or rotate relative to the base 22 in the vertical direction, operation is convenient, and meanwhile, the efficiency of locking or unlocking the battery pack 1 is improved.

As shown in fig. 7, 8 and 9, the lock base 31 has a connecting channel 32 extending in the vertical direction, and a catch 33 disposed adjacent to the connecting channel 32, the connecting channel 32 is used for moving the hanging portion 212 upward in the vertical direction to a position corresponding to the catch 33, and the hanging portion 212 is locked to the catch 33 by rotation. Specifically, the catches 33 are arranged in the horizontal direction, and the hanging portion 212 moves within the connecting passage 32, rotates to a height corresponding to the catches 33, and is hung on the catches 33, as shown in fig. 5, 7, and 8. As shown in fig. 6, when the hanging portion 212 is rotated to a position opposite to the connecting channel 32, it can move downward along the connecting channel 32 to disengage from the lock base 31 for unlocking. Wherein, the connecting channel 32 matches with the shape of the hanging part 212, so that the locking rod can move up and down.

Preferably, the catch 33 is further provided with a guide surface 331, and the guide surface 331 is disposed obliquely upward or obliquely downward from the connection passage 32. The hanging part 212 can be guided from the connecting channel 32 to the clamping part 33 through the guide surface 331, so that the hanging part 212 can be smoothly hung on the clamping part 33 from the connecting channel 32, and the locking is realized.

Further, as shown in fig. 4 and 9, the base 22 includes an outer base 27 and an inner clamping seat 28, the inner clamping seat 28 is in threaded connection with the outer base 27, and a locking groove is formed on the inner clamping seat 28, and is a spiral groove 281 for the T-shaped locking rod 21 to ascend and descend or rotate in the vertical direction. By providing the spiral groove 281 on the inner cassette 28 to cooperate with the T-shaped lock lever 21, the T-shaped lock lever 21 can be lifted and lowered in the vertical direction at the same time when rotating in the axial direction thereof. As shown in fig. 2, the two opposite sides of the battery pack 1 are provided with the locking members 200, and when the battery pack 1 is locked with the battery replacement vehicle, the two opposite sides of the battery pack 1 can be connected with the battery replacement vehicle, so that the gravity of the battery pack 1 is borne by the two sides, the overall stress condition of the battery pack 1 is balanced, and the reliability of connection between the battery pack 1 and the battery replacement vehicle is improved. In other embodiments, the locking member 200 may be disposed at other positions of the battery pack 1, such as at the middle position of the battery pack 1.

In the present embodiment, as shown in fig. 2, the battery pack 1 includes a case 2 and a battery body located inside the case 2. The box body 2 is of a frame structure, the frame structure is provided with a mounting plate 3, and the locking piece 200 is detachably connected to the mounting plate 3. The case 2 has a frame structure, and can reliably support and protect the battery body on the basis of reducing cost and weight. The arrangement of the mounting plate 3 not only facilitates the connection between the lock shaft and the box body, but also increases the contact area between the lock shaft (particularly the fixed end of the lock shaft) and the box body, and is favorable for improving the connection reliability between the lock shaft and the battery pack. In addition, the installation plate 3 can also play a role in increasing the strength of the box body.

As shown in fig. 2, the T-shaped lock levers 21 of each lock member 200 are arranged at intervals along the direction in which the long side 111 of the case 2 extends. Compared with the extension direction of the short side 112 of the box body 2, the extension direction of the long side 111 of the box body 2 bears more weight of the battery pack 1, the lock rods of each locking piece 200 are arranged at intervals along the extension direction of the long side 111 of the box body 2, more weight of the battery pack 1 is borne, the situation that the box body 2 is likely to sag or deform at the middle position of the extension direction of the long side 111 due to the fact that the box body does not have the bearing capacity of the lock rods is avoided, and therefore the reliability of the locking piece 200 for bearing the battery pack 1 is improved.

Further, as shown in fig. 2, the locking member 200 of each side is provided with four T-shaped locking levers 21 and is disposed at regular intervals along the length direction of the battery pack 1. Accordingly, the number of the T-shaped lock levers 21 can be adjusted accordingly according to the volume size or weight of the battery pack 1; for example, when the battery pack 1 has a small volume or the short side 112 thereof is provided with the locking member 200 in the extending direction, only one T-shaped lock lever 21, that is, only two T-shaped lock levers 21 may be provided at each end of the locking member 200 as needed. Moreover, the interval arrangement distance of the T-shaped lock rods 21 can be correspondingly adjusted according to the number of the T-shaped lock rods 21, the gravity distribution of the battery pack 1, the size of the box body 2 and other factors; the axial direction of the T-shaped lock lever 21 may also be arranged along the extending direction parallel to the long side 111 of the box 2, and at this time, only the arrangement angle of the locking mechanism 300 needs to be adjusted correspondingly, which is not described herein again.
