In addition, the rotation locking mode is simple and reliable, locking is carried out through the T-shaped rotation mode, rotation of the structure for limiting T-shaped rotation after locking is convenient, and locking is reliable, even if the battery pack 1 and the battery replacement vehicle are connected reliably.
In the present embodiment, a structure of the T-shaped rotation locking system is disclosed, which can be described in the related art of patent publication No. CN114523833A, but it is needless to say that a specific structural form of the T-shaped rotation locking system is not limited to the one of patent publication No. CN114523833A, and may be other structural forms, and the specific structural form may not be limited.
For example, as a preferred embodiment, the present embodiment provides a structure of a more preferred T-shaped rotation locking manner, and in particular, as shown in fig. 4 to 9, a locking assembly 100, which is applied to a locking member 200 and a locking mechanism 300 in the T-shaped rotation locking manner, and the T-shaped rotation locking of the battery pack 1 and the electric vehicle is realized through the mutual cooperation of the locking member 200 and the locking mechanism 300, where the locking member 200 and the locking mechanism 300 are a T-shaped lock rod 21 and a lock seat 31, respectively; the specific types of the locking member 200 and the locking mechanism 300 can be selected according to the actual situations of the battery pack 1 and the electric vehicle, and the locking member 200 may be a T-shaped lock rod 21, the locking mechanism 300 may be a lock holder 31, or the locking member 200 may be a lock holder 31, and the locking mechanism 300 may be a T-shaped lock rod 21. When one of the T-shaped lock lever 21 and the lock holder 31 is provided on the battery pack 1, the other of the T-shaped lock lever 21 and the lock holder 31 is provided on the electric vehicle. The T-shaped lock rod 21 and the lock seat 31 are detachably connected to independently lock the battery pack 1 on the battery replacement vehicle. Therefore, the T-shaped rotary locking of the battery pack 1 and the battery replacing vehicle is realized through the matching of the T-shaped lock rod 21 and the lock seat 31, and the structure is simple, reliable and convenient to realize.
Specifically, in the present embodiment, as shown in fig. 2, the locking member 200 is a T-shaped lock bar 21 and is disposed on the top of the box body 2 of the battery pack 1. Accordingly, the locking mechanism 300 is a lock seat 31 and is disposed on the electric vehicle (not shown in the figure), specifically, the lock seat 31 is disposed on the quick-change bracket 8 and is located at the bottom of the electric vehicle.
As shown in fig. 4, the T-shaped lock lever 21 includes a shaft body 211, and at least one hanging part 212 extending outward from one end of the shaft body 211, and the T-shaped lock lever 21 is rotatably locked at the locking position of the lock base 31 by the hanging part 212. As shown in fig. 5, 7 and 8, the hanging part 212 rotates to the locking position of the lock base 31 and abuts against the lock base 31, so that the T-shaped lock lever 21 and the lock base 31 are locked, and the battery pack 1 is connected to the electric vehicle. As shown in fig. 6, when the hanging part 212 rotates to the unlocking position of the lock base 31, the hanging part 212 can move up and down to separate from the lock base 31, so as to unlock the T-shaped lock lever 21 and the lock base 31, and thus the battery pack 1 can be separated from the electric vehicle.
As shown in fig. 9, the T-shaped lock lever 21 includes two hanging portions 212, and the two hanging portions 212 extend in opposite directions from one end of the shaft body 211, respectively. The T-shaped lock rod 21 can be contacted with the lock seat 31 at two positions, so that the contact area between the T-shaped lock rod 21 and the lock seat 31 is increased, and the locking stability is improved. In addition, the two hanging parts 212 extend along opposite directions, so that the locking balance can be improved; moreover, when one of the hanging parts 212 rotates in place during unlocking, the other hanging part 212 also rotates in place along with the rotation, and the unlocking efficiency is improved.
Specifically, as shown in fig. 9, the two hanging portions 212 are disposed at the top of the shaft body 211, and the extending directions of the two hanging portions 212 are perpendicular to the axial direction of the shaft body 211, so that the contact area between the hanging portions 212 and the lock seat 31 is larger, and the locking is more stable. As shown in fig. 9, the shaft body 211 has a cylindrical structure, and the hanging part 212 has a rectangular cylindrical structure. As shown in fig. 2, the hanging portion 212 may have a cylindrical structure.
Specifically, the T-shaped lock lever 21 further includes a locking portion 213, the locking portion 213 is disposed at the other end of the shaft body 211, and the locking portion 213 is used for limiting the rotation of the hanging portion 212 relative to the lock base 31 when the hanging portion 212 is located at the locking position of the lock base 31. Through setting up locking portion 213, can avoid the unexpected rotation of T type locking lever 21 when the locking, promote the reliability of locking for the stability of the electricity connection between battery package 1 and the electric vehicle can be promoted.
In this embodiment, the anti-loose part 213 is a nut and is engaged with the shaft body 211 to prevent loosening. In other alternative embodiments, the anti-loose part 213 can also limit the rotation of the hanging part 212 relative to the lock seat 31 by one of the engagement modes of ratchet, pawl, bead, snap and engagement.
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 restricts the moving direction of the T-shaped lock rod 21, so that the T-shaped lock rod 21 can be lifted or rotated relative to the base 22, and the T-shaped lock rod 21 can move along the vertical direction by configuring the orientation of the chamber for accommodating the T-shaped lock rod 21 in the base 22, thereby improving the accuracy of locking and unlocking.
Specifically, the base 22 is a cylindrical structure having a through hole for the T-shaped lock lever 21 to pass through, so that the base 22 restricts the moving direction of the T-shaped lock lever 21. When the battery pack moves along the vertical direction to be installed or detached, the T-shaped lock rod 21 is lifted along the vertical direction, so that the moving process of the battery pack is combined with the locking mechanism and the vertical locking process of the locking piece, and the locking efficiency is improved. Meanwhile, the T-shaped lock rod 21 is lifted along the vertical direction, so that the T-shaped lock rod 21 can be prevented from interfering with parts in the horizontal direction when moving, and the structure is compact.
In this embodiment, the T-shaped lock lever 21 is further provided with a driving portion (not shown in the figure), 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.
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 on 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 passage 32, it can be moved downward along the connecting passage 32 to disengage from the lock housing 31 for unlocking. The shape of the connecting channel 32 is matched with that of the hanging part 212, so that the hanging part 212 can move in the connecting channel 32, and the locking or unlocking is favorably and smoothly performed.
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 to the clamping part 33 from the connecting channel 32 through the guide surface 331, and the guide surface 331 on the clamping part 33 has a certain angle with the horizontal plane, so that the clamping part 33 and the hanging part 212 form inclined self-locking after being locked, and the locking is reliable.
Further, the base 22 includes an outer base 2211 and an inner base 2212, the inner base 2212 is connected with the outer base 2211 by screw threads, and a locking groove 2213 is formed on the inner base 2212 to be matched with the T-shaped locking rod 21, so that the T-shaped locking rod 21 can be lifted and lowered in the vertical direction when rotating along the axial direction of the T-shaped locking rod. Among them, the shape of the locking groove 2213 may be determined according to the moving path of the T-shaped locking bar 21, and a spiral groove may be preferable in this embodiment.
As shown in fig. 2, the locking members 200 are disposed on two opposite sides of the battery pack 1, and when the battery pack 1 is locked with the electric vehicle, the two opposite sides of the battery pack 1 can be connected with the electric vehicle, so that the gravity of the battery pack 1 is borne by the two sides, the overall stress of the battery pack 1 is balanced, and the reliability of connection between the battery pack 1 and the electric 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.
As shown in fig. 2, the locking member 200 includes at least two T-shaped locking levers 21, and the at least two T-shaped locking levers 21 are arranged at intervals along the same direction of the housing 2. Compared with the situation that only one T-shaped locking rod 21 is provided, more T-shaped locking rods 21 are provided for bearing the battery pack 1, and the bearing reliability and the bearing stability of the battery pack 1 are facilitated. At least two T-shaped locking rods 21 are arranged at intervals along the same direction of the box body 2, so that more T-shaped locking rods 21 on the battery pack 1 in the same direction of the box body 2 bear the gravity of the battery pack 1, the T-shaped locking rods are arranged at intervals, the stress of the battery pack 1 at different positions is balanced, and the reliability of the locking piece 200 for bearing the battery pack 1 is improved.
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 extending direction of the short sides 112 of the box body 2, the extending direction of the long sides 111 of the box body 2 bears more weight of the battery pack 1, the T-shaped lock rods 21 of each locking piece 200 are arranged at intervals along the extending direction of the long sides 111 of the box body 2, more weight of the battery pack 1 is borne, the box body 2 is prevented from sagging or deforming at the middle position of the extending direction of the long sides 111 of the box body 2 due to the fact that no lock rod bears the load, and therefore reliability of the locking piece 200 for bearing the battery pack 1 is improved.

The T-shaped lock rods 21 are arranged in parallel, so that the horizontal angles of the T-shaped lock rods 21 are uniform, and when the locking mechanisms 300 and the locking pieces 200 move vertically, the pairing angles of the locking mechanisms 300 and the corresponding locking pieces 200 are uniform, and the possibility of pairing faults is reduced.
As shown in fig. 2, the T-shaped lock lever 21 is disposed in an axial direction perpendicular to the direction in which the long side 111 of the case 2 extends.
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 volume of the battery pack 1 is small or the short side 112 of the battery pack is also provided with the locking member 200, only one T-shaped locking lever 21, that is, only two T-shaped locking levers 21 may be provided at both ends 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 T-shaped lock lever 21 may also be disposed along a direction parallel to the extending direction of the long side 111 of the box 2, and at this time, only the setting angle of the locking mechanism 300 needs to be adjusted correspondingly, which is not described herein again.
As shown in fig. 2, the T-shaped lock levers 21 of the two-sided lock members 200 are disposed in one-to-one correspondence, so that the lock members 200 of the two sides form a symmetrical structure. When the battery pack 1 is locked and unlocked with the electric vehicle, the locking pieces 200 on the two sides act in the same way, so that the unlocking and locking efficiency and reliability are improved.
As shown in fig. 2, the upper surface of the box body 2 is provided with a recessed structure, the locking member 200 is arranged in the recessed structure, and the connection position of the T-shaped lock lever 21 and the mounting bracket 3 is not higher than the upper surface of the box body 2.
