In addition, the utility model installs the battery system on the installation unit that can serve as the crossbeam structure of the frame.

[0012] The following is a detailed description of an embodiment of the utility model in conjunction with the accompanying drawings. This embodiment is implemented on the premise of the technical solution of the utility model, and a detailed implementation method and a specific operation process are given, but the protection scope of the utility model is not limited to the following embodiment.

[0013] It should be noted that, in the description of the present utility model, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0014] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" that may appear should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0015] like Figure 1-3 As shown, the non-load-bearing frame structure integrated with a battery system described in the utility model comprises a frame body having a pair of longitudinal beams 1 and a mounting unit for fixing the battery system; the mounting unit is arranged between the two longitudinal beams 1, and comprises a transverse frame beam 2, a bottom plate 3 and a longitudinal frame beam 4 welded to the inner side of each longitudinal beam 1, and the two ends of each transverse frame beam 2 are respectively welded to the corresponding longitudinal beam 1, and the transverse frame beam 2 adopts a plate-like structure and its bottom is consistent with the bottom surface of the longitudinal beam 1, which can maximize the use of the z-direction space and facilitate the installation of the battery assembly;

[0016] Two transverse frame beams 2 and two longitudinal frame beams 4 are alternately arranged to surround a rectangular frame, the bottom plate 3 is welded to the bottom of the rectangular frame and the bottom plate 3 is also welded to the longitudinal beam 1, the longitudinal beam 1, the transverse frame beam 2 and the bottom plate 3 surround an installation box for installing a battery assembly, the battery assembly 6 is fixed in the installation box, and then the box cover 5 of the battery system is fixed on the longitudinal frame beam 4, forming an enclosed space, which can better protect the battery assembly; the utility model welds the installation unit and the longitudinal beam 1 together, which not only realizes the integrated installation of the battery system on the frame, occupies a small space and improves the space utilization rate; the transverse frame can also serve as the crossbeam of the frame, thereby reducing unnecessary installation brackets and crossbeams, reducing parts, reducing weight, which is beneficial to the lightweight of the vehicle, and improving the energy density and cruising range of the battery system; the utility model installs the battery system on a mounting unit that can serve as a crossbeam structure of the frame. During the driving of the vehicle, the battery system will not bear additional loads, thereby improving the overall structural strength of the frame and the safety of the battery.

[0017] Combination Figure 1 It can be seen that at least two reinforcing cross beams 7 are welded between the two longitudinal beams 1, and the two ends of the reinforcing cross beam 7 are respectively welded to the longitudinal beams 1. The reinforcing cross beam 7 is located in the installation box, and the battery assembly can be fixed in the installation box by bolts to provide an installation basis for the battery assembly. The reinforcing cross beam 7, like the horizontal frame beam 2, can also be used as a cross beam of the frame, thereby improving the structural strength of the frame. In actual processing, two downwardly protruding reinforcing protrusions 8 can also be processed on the bottom plate 3 to enhance the structural strength.
