Embodiment Construction
[0033] In order to enable the examiner to further understand the structure, features and other purposes of the present invention, the attached preferred embodiments are now attached with accompanying drawings in detail as follows. The embodiments illustrated in the accompanying drawings are only used to illustrate the technical solution of the present invention , not to limit the present invention.
[0034] Such as figure 1 as shown, figure 1 It is a schematic diagram of a cross-section of the groove 1 of the present invention, and the groove 1 is composed of a bottom surface and left and right sides perpendicular to the bottom surface. Groove 1 can be a cross-section of uniform thickness or a cross-section of unequal thickness. The thickness depends on the material and production process. When using sheet pressure molding, it usually has a uniform thickness; when using pultrusion profiles or injection molding, casting , Forging molding and other mold forming processes usual...

The invention provides a battery box with multiple annular cross section structures. The battery box comprises a plurality of troughs, end plates, covers and bulges; the troughs consist of bottom faces, left side faces and right side faces, the left side faces and the right side faces are vertical to the bottom faces, the troughs are horizontally arranged in parallel in the same direction, and the adjacent troughs are adhered together; the end plates are respectively arranged at two ends of each trough to seal the two ends of each trough, and grooves corresponding to the shapes of the cross sections of the troughs are formed in the end plates; the covers are correspondingly arranged at openings of the troughs, the cross sections of the covers are of downward opening slot shapes, and the covers and the troughs are fixed together to seal longitudinal openings of the troughs; the bulges are arranged at two side walls of each trough at intervals; the troughs and the covers are combined to form the closed annular cross section structures, and the battery box is formed by multiple structures with the annular cross sections. Therefore, the battery box has the advantages of less number of parts, light weight, easiness in batch production, thermal isolation and insulation, and has a positive and important significance to the improvement of the energy density of a battery pack.
Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and more specifically relates to a battery box with multiple annular cross-section structures, which belongs to the power battery grouping technology. Background technique [0002] As the energy storage component of electric vehicles, the battery box has a large number of power batteries installed inside; at present, a single battery box of large freight and passenger vehicles generally loads tens to hundreds of kilograms of power batteries. [0003] It has been found in practice that most of the known battery box structures are single-layer shell-like enclosure structures, that is, the main structure of the battery box is formed by the outer surface of the battery box; The group deforms and cannot withstand higher overloads. Contents of the invention [0004] In order to solve the shortcomings of the prior art above, the present invention provides a battery box structure with greate...
