[0029] See also Figure 1 and Figure 2 The first connection portion includes a connection sleeve 110 longitudinally penetrating the longitudinal beam assembly side 100, the connection sleeve 110 is fixedly connected to the longitudinal beam assembly side 100, and the connection sleeve 110 is detachably connected to the mounting hole on the floor longitudinal beam through bolts.

[0030] Specifically, a first through hole is provided on the upper end surface of the longitudinal beam assembly side 100, and a second through hole is provided on the lower end surface of the longitudinal beam assembly side 100. The diameter of the first through hole matches the outer diameter of the connecting sleeve 110, and the diameter of the second through hole is smaller than the outer diameter of the connecting sleeve 110 and larger than the inner diameter of the connecting sleeve 110. The connecting sleeve 110 vertically penetrates into the interior of the longitudinal beam assembly side 100 from top to bottom through the first through hole, and the lower end of the connecting sleeve 110 abuts against the bottom of the inner cavity of the longitudinal beam assembly side 100. A bolt penetrates into the inner hole of the connecting sleeve 110 from bottom to top, and the upper end of the bolt penetrates into the corresponding mounting hole on the floor longitudinal beam, and a nut is tightened on the upper end of the bolt, and a plurality of bolts are sequentially connected with the nuts to the connecting sleeve 110 and the mounting holes on the floor longitudinal beam, thereby completing the connection between the longitudinal beam assembly side 100 and the floor longitudinal beam.

[0031] In addition, the outer wall of the connecting sleeve 110 is welded and fixed to the longitudinal beam assembly side 100. The connecting sleeve 110 and the first through hole are circumferentially welded or spot welded to fix the connecting sleeve 110 to the longitudinal beam assembly side 100 of the adapter beam body.

[0032] Preferably, the connecting sleeve 110 is made of aluminum alloy, and the connecting sleeve 110 and the transfer beam body are made of the same material, so that the welding performance of the two is better and the combination is more stable.

[0033] See also Figure 1 and Figure 3 The second connection part includes an internal threaded sleeve 210 longitudinally penetrated through the battery pack side 200, and a connecting plate 220 is provided on the upper part of the internal threaded sleeve 210. The connecting plate 220 is fixed to the upper end surface of the battery pack side 200, and the internal threaded sleeve 210 is detachably connected to the mounting hole on the battery pack by bolts.

[0034] Specifically, a third through hole is provided on the upper end surface of the battery pack assembly side 200, and a fourth through hole is provided on the lower end surface of the battery pack assembly side 200. The diameter of the third through hole is adapted to the outer diameter of the internal threaded sleeve 210, and the diameter of the fourth through hole is smaller than the outer diameter of the internal threaded sleeve 210 and larger than the inner diameter of the internal threaded sleeve 210. The internal threaded sleeve 210 vertically penetrates the interior of the battery pack assembly side 200 from top to bottom through the third through hole, the lower end of the internal threaded sleeve 210 abuts against the bottom of the inner cavity of the battery pack assembly side 200, and the connecting plate 220 is fixed to the upper end surface of the battery pack assembly side 200.

The upper end surface of the longitudinal beam assembly side 100 of the transfer beam body is higher than the upper end surface of the battery pack assembly side 200, so that in the event of a collision, the transfer beam body with a hollow structure can be squeezed to collapse and absorb energy, thereby protecting the battery pack. In addition, the upper area of ​​the battery pack assembly side 200 forms a clearance space, which can provide corresponding space for the upper end of the bolt connecting the battery pack. Therefore, the bolts connecting the battery pack have a wider range of optional lengths and are more applicable.

Through the positioning relationship between the first positioning pin 120 and the floor longitudinal beam and the second positioning pin 230 and the battery pack, the multiple connecting sleeves 110 on the longitudinal beam assembly side 100 correspond coaxially with the multiple mounting holes on the floor longitudinal beam. At the same time, the multiple internal threaded sleeves 210 on the battery pack assembly side 200 correspond coaxially with the multiple mounting holes on the battery pack, so as to facilitate the subsequent use of corresponding bolts to complete the quick connection between the transfer beam body and the floor longitudinal beam and the battery pack.
