Abstract

The invention discloses a lithium battery cover plate and lower insulation pad connecting structure capable of realizing efficient assembly. The structure comprises a lower insulation pad and a coverplate attached to the surface of the lower insulation pad; the lower surface of the cover plate is provided with a plurality of buckle hook portions, and the lower insulation pad is provided with buckle protruding portions which are matched with the buckle hook portions in a one-to-one correspondence mode to achieve buckling connection of the lower insulation pad and the cover plate. According tothe invention, the ultrasonic welding of an insulating pad and a cover plate in a traditional structure is canceled, and a snap fastener mode is adopted, so the performance stability and the assemblyquickness of the battery cover plate are improved.

Description

【Technical field】 [0001] The invention relates to a connection structure between a lithium battery cover plate and a lower insulating pad capable of realizing high-efficiency assembly. 【Background technique】 [0002] New energy vehicles have gradually become the trend of automobile development, and the power source of new energy vehicles mainly comes from power battery packs. When the power lithium battery is installed on the power vehicle, the lithium battery will be placed in a box to form a battery pack. The battery pack is provided with a cover to close it, and the electrical conduction is realized through the electrical components provided on the cover. The battery cover plate includes a lower insulating pad, a cover plate, and a positive electrode assembly and a negative electrode assembly arranged on the cover plate. In the prior art, the assembly structure of the lower insulating pad and the cover plate is directly welded by ultrasonic welding between the lithium ba...
