Abstract
The invention is applicable to the technical field of electric vehicle power batteries, and discloses a heat insulation structure, a battery module, an assembly method of the automobile and the battery module. The heat insulation structure is used to be arranged between adjacent batteries or battery core groups, and the heat insulation structure includes a heat insulation sheet formed by coating and encapsulating airgel, and the opposite ends of the heat insulation sheet are both A limit assembly is provided, and the limit assembly includes a first limit piece, a second limit piece and a connecting piece that cooperates with the first limit piece and is clamped on the corresponding end of the heat insulation sheet, and the connecting piece is used for The second limiting member is fixedly connected to the first limiting member. The invention provides a heat insulation structure, a battery module, an automobile and a battery module assembly method, which adopts a heat insulation sheet formed by coating and encapsulating airgel, and sets limiters at opposite ends of the heat insulation sheet. Assembled with components, the structure and manufacturing process are simple, the cost is low, and the heat insulation effect is better, which is beneficial to the control of heat spread.
Description
technical field [0001] The invention belongs to the technical field of power batteries for electric vehicles, and in particular relates to a heat insulation structure, a battery module, an automobile and an assembly method for the battery module. Background technique [0002] At present, the heat insulation structure used between the cells adopts a back-shaped plastic frame (silica gel frame) filled with airgel in the middle, and is packaged with PI / PET film. The heat insulation structure of this design has complicated process, high packaging cost, and the heat insulation effect of the return frame part is relatively poor, which is not conducive to the control of heat spread. Contents of the invention [0003] The present invention aims to solve at least one of the above-mentioned technical problems, and provides a heat insulation structure, battery module, automobile and battery module assembly method, using a heat insulation sheet formed by coating and encapsulating airg...
