[0002] With the rapid development of the new energy vehicle industry, the battery pack, as a core component, has become one of the key factors restricting the popularization of new energy vehicles. For vehicles with lower chassis, traditional battery replacement methods mainly adopt sinking or lifting methods. The sinking battery replacement requires digging a pit to accommodate the battery replacement equipment, which not only increases the construction cost, but also faces problems such as large floor space, complicated procedures, and many environmental restrictions, which seriously restricts the flexibility and portability of the battery replacement equipment. Although the lifting battery replacement avoids the construction of the pit, its equipment cost is high, the operation is time-consuming, and the track accuracy requirements are extremely high, which further increases the difficulty of implementation.

[0057] The flat battery replacement module provided by the present invention has the following working principle:

[0058] After installing the base for battery replacement at the bottom of the vehicle, the battery pack is aligned with the battery replacement area of ​​the vehicle through the operation of the battery replacement module.

[0059] In this process, the traction assembly 5 drives the first driving device 2 to move along the x direction, thereby driving the floating platform 3 and the second driving device 4 to move along the x direction, thereby realizing the transportation of the battery pack and adjusting the position of the battery pack in the x direction.

[0062] In addition, if there is an angular deviation between the battery pack and the battery exchange area, the lifting heights of the two lifting components can be made inconsistent to drive the floating platform 3 to rotate, thereby realizing the rotation of the battery pack parallel to the xz plane. The floating platform 3 is driven to rotate by the first rotating component to realize the rotation of the battery pack parallel to the yz plane.
