Claims

1. A floating component for an offline battery swapping device for vehicles, comprising: A first plate layer, the first plate layer being configured to be fixedly connected to an offline battery swapping device; The second plate layer is configured to be floatably positioned above the first plate layer relative to the first plate layer; A floating support structure, each floating support structure consisting of a first unit component fixedly connected to a first plate layer and a second unit component fixedly connected to a second plate layer; The first and second individual components are configured to directly engage with each other in a sliding manner. A floating restraint structure is provided to limit the floating of the second plate layer relative to the first plate layer. The floating restraint structure is separate from the floating support structure and is configured to extend at least through the thickness of the second plate layer. The floating restraint structure includes a collar, which includes a sleeve and a collar flange integrally extending radially outward from one end of the sleeve. The sleeve is positioned inside a corresponding inner hole in the second plate, and the collar flange is used to be fixedly connected to the surface of the second plate facing or away from the first plate. The collar flange includes multiple through holes distributed around the sleeve. These through holes are used for the detachable connection between the collar and the second plate layer, thereby facilitating the adjustment of the floating limit.

2. The floating component according to claim 1, wherein, One of the two individual components of the floating support structure includes a bushing for fixedly connecting to a first surface of the opposing surfaces of the first and second plates. The bushing has an arc-shaped groove for facing the second surface of the opposing surfaces of the first and second plates. The other of the two individual components of the floating support structure includes a support column for fixedly connecting to a second surface of the opposing surfaces of the first and second plates, the support column being provided with an arcuate protrusion facing the first surface of the opposing surfaces of the first and second plates.

3. The floating component according to claim 1, wherein, The floating component does not include internal moving parts.

4. The floating component according to claim 2, wherein, The arcuate groove defines a shape that roughly corresponds to a portion of an ellipsoid, and the outer contour dimension decreases continuously along the concave direction; and / or The arc-shaped protrusion defines a shape that roughly corresponds to a portion of an ellipsoid, and the outer contour dimension decreases continuously along the outward convex direction.

5. The floating component according to claim 2, wherein, The arc-shaped grooves and / or arc-shaped protrusions define a generally centrally symmetrical shape.

6. The floating component according to claim 2, wherein, The maximum outer contour dimension of the arc-shaped protrusion along the outward convex direction is smaller than the maximum outer contour dimension of the arc-shaped groove along the inward concave direction, and / or The radius of curvature of the deepest part of the arc-shaped groove along the concave direction is greater than the radius of curvature of the highest point of the arc-shaped protrusion along the convex direction.

7. The floating component according to claim 1, wherein, The floating restraint structure includes a base comprising a base flange for fixed connection to a first plate layer and a shaft extending integrally from the base flange in a generally vertical manner, the length of the shaft being configured to extend through a corresponding inner hole in a second plate layer within the floating assembly.

8. The floating component according to claim 7, wherein, The floating restraint structure includes a baffle that is fixedly connected to the top of the shaft above the second plate layer, and the baffle is sized to prevent the second plate layer from being lifted off the baffle.

9. The floating component according to claim 8, wherein, There is a gap between the lower surface of the cover and the highest vertical height of the second plate in the area below the cover, and there is a gap between the upper surface of the base flange and the lowest vertical height of the second plate in the area above the base flange.

10. The floating component according to claim 8, wherein, There is a gap between the lower surface of the cover and the highest vertical height of the area of ​​the second plate below the cover, including the collar, and there is a gap between the upper surface of the base flange and the lowest vertical height of the area of ​​the second plate above the base flange, including the collar.

11. The floating component according to claim 1, wherein, The first and second slabs together define the roughly orthogonal longitudinal and transverse directions. Multiple floating support structures are arranged at intervals between the first and second slabs along the first and second rows, which are roughly parallel to the longitudinal direction.

12. The floating component according to claim 11, wherein, The floating restraint structure is arranged in the lateral direction between the first and second rows and / or at approximately equal distances from the first and second rows in the lateral direction.

13. The floating component according to claim 11 or 12, wherein, Two floating restraint structures are arranged at intervals along a third row that is generally parallel to the longitudinal direction in two opposite end regions along the longitudinal direction.

14. An offline battery swapping device for a vehicle, comprising a support structure and a floating component according to any one of claims 1 to 13, wherein, The first plate of the floating component is fixedly connected to the support structure of the offline battery swapping equipment.

15. The offline battery swapping device according to claim 14, wherein, At least a portion of the support structure of the offline battery swapping equipment is configured to allow the floating components to be lifted relative to the vehicle from below.
