[0029] Before any embodiments of the present application are explained in detail, it is to be understood that the application is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0030] In this application, the terms "comprises," "includes," "has," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not preclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0031] In this application, the term "and / or" is a description of the association relationship between related objects, indicating that three relationships can exist. For example, a centrifugal vortex magnetic pump and / or a centrifugal vortex magnetic pump can represent three situations: the existence of a centrifugal vortex magnetic pump alone, the existence of a centrifugal vortex magnetic pump and a centrifugal vortex magnetic pump at the same time, and the existence of a centrifugal vortex magnetic pump alone. In addition, the character " / " in this application generally indicates that the related objects are in an "and / or" relationship.

[0032] In this application, the terms "connect," "combine," "couple," and "install" may refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without an intermediary, and an indirect connection refers to two parts or components being connected to at least one intermediary, with the two parts or components being connected via the intermediary. Furthermore, "connect" and "couple" are not limited to physical or mechanical connections or couplings and may include electrical connections or couplings.

[0033] In this application, it will be understood by those skilled in the art that relative terms (e.g., "about," "approximately," "substantially," etc.) used in conjunction with quantities or conditions include the values ​​and have the meaning indicated by the context. For example, the relative terms include at least the degree of error associated with the measurement of a specific value, the tolerance caused by manufacturing, assembly, use, etc. associated with a specific value. Such terms should also be considered to disclose a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to plus or minus a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​that do not use relative terms should also be disclosed as specific values ​​with tolerances. In addition, "substantially" may refer to plus or minus a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) on the basis of the indicated angle when expressing a relative angular position relationship (e.g., substantially parallel, substantially perpendicular).

[0034] In this application, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0035] In the present application, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present application. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front and lower back, etc.

[0036] Traditional single beams or simple structures struggle to meet the requirements of heavy loads and long overhangs, and are prone to excessive deflection and deformation, impacting the normal operation and safety of the battery swapping equipment. Furthermore, the lateral loads imposed by the battery swapping equipment and its frequent operation can also cause bending and torsional deformation in the load-bearing beams.

[0037] See also Figures 1 to 3 This embodiment provides a load-bearing beam structure, which is arranged in a container 100 and is used to carry a battery exchange device 200. The load-bearing beam structure includes at least two rail steels 1, a base plate 2, multiple support columns 3 and a connecting component.

[0038] Among them, all rail steels 1 are arranged side by side on the base plate 2 and form a load-bearing beam for carrying the battery exchange equipment 200. In this embodiment, two rail steels 1 are provided, and the specific model of the rail steel 1 can be selected according to the actual application scenario, such as U71Mn / 50Mn with a specification of 50kg / m.

[0039] Multiple support columns 3 are vertically mounted on the frame of the container 100 and are used to support the floor 2. Each support column 3 is connected to the floor 2 via a connecting assembly, with the number of connecting assemblies corresponding to the number of support columns 3. In this embodiment, two support columns 3 are provided, one at each end of the floor 2, that is, the two support columns 3 are used to support the two ends of the load-bearing beam.

[0040] It can be understood that the load-bearing beam composed of multiple rail steels 1 arranged side by side has good load-bearing capacity and bending resistance, is not prone to excessive deflection and deformation, and can ensure the normal operation and safety of the battery exchange equipment 200.

[0041] To enhance the structural strength of the load-bearing beam, all rail steels 1 are welded to the base plate 2. This arrangement creates a stable beam structure, and the base plate 2, installed at the bottom of the multiple rail steels 1, increases the cross-sectional modulus of the load-bearing beam, thereby further improving the bending and torsional resistance of the load-bearing beam and reducing deflection and deformation under load.

[0042] It is worth noting that if the connection between the load-bearing beam and the frame of the container 100 is unreliable, the load-bearing beam is prone to tilt, displacement or vibration under the load applied by the battery swap equipment 200, causing the connection position between the load-bearing beam and the frame of the container 100 to shift, thereby affecting the positioning accuracy and operational reliability of the battery swap equipment 200. Therefore, supporting the load-bearing beam with multiple support columns 3 can avoid the situation where the connection position between the load-bearing beam and the frame of the container 100 shifts.

[0043] Specifically, the connection assembly includes a connecting plate 4 and a plurality of bolts (not shown). The connecting plate 4 is mounted on top of the support column 3. The bolts pass through the base plate 2 and are screwed onto the connecting plate 4, thereby integrally connecting the base plate 2 and the connecting plate 4. In this embodiment, each support column 3 comprises two side-by-side columns, thereby enhancing the structural strength of the support column 3. The connecting plate 4 is welded to the top of the two columns.

[0044] It should be noted that the use of multiple bolts to connect the connecting plate 4 and the bottom plate 2 has a compact structure and takes up little space. Of course, other existing external connection structures can also be used in other containers 100 with open space, which will not be described in detail.

[0045] In order to further improve the connection reliability between the support column 3 and the frame of the container 100, the side of the connecting plate 4 away from the support column 3 is connected to the frame of the container 100. The specific connection method can be welding or screw connection. This embodiment does not make specific requirements and restrictions on this.

[0046] In order to further improve the connection reliability between the support columns 3 and the frame of the container 100 , the load-bearing beam structure further includes a reinforcement component 5 , and multiple groups of support columns 3 are connected to the frame of the container 100 through the reinforcement component 5 .

[0047] Specifically, the reinforcement assembly 5 includes a plurality of reinforcing ribs 51, which are evenly distributed between the support column 3 and the frame of the container 100. Each rib 51 has two ends connected to the support column 3 and the frame of the container 100, and each rib 51 extends horizontally. This arrangement ensures that the support column 3 is securely connected to the frame of the container 100 at multiple locations, making it less susceptible to tilting or deformation. It should be noted that the reinforcing ribs 51 can be connected to the support column 3 and the frame of the container 100 by welding or screwing, and this embodiment does not impose any specific requirements or limitations on this.

[0048] Furthermore, the reinforcement assembly 5 includes multiple diagonal braces 52. Any two adjacent reinforcement bars 51 are connected by a diagonal brace 52, and each diagonal brace 52 extends in an oblique direction. The square support structure formed by the two adjacent reinforcement bars 51, the support column 3, and the frame of the container 100 is divided into two triangular support structures by the diagonal braces 52, thereby better resisting bending moments and horizontal forces from the load-bearing beams.

[0049] This embodiment further provides a battery swap station, comprising a container 100, a battery swap device 200, and the aforementioned load-bearing beam structure, wherein the load-bearing beam structure is disposed within the container 100 and is used to support the running wheels of the battery swap device 200. It will be appreciated that the battery swap station including the aforementioned load-bearing beam structure can ensure the normal operation and safety of the battery swap device 200.

[0050] In this embodiment, two load-bearing beam structures are provided, and the two load-bearing beam structures are respectively located at the two ends of the length direction of the container 100, and the two sets of running wheels of the battery exchange equipment 200 can run on the two load-bearing beam structures respectively.

[0051] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
