Tray, tray assembly, battery pack assembly and vehicle

Abstract

The invention discloses a tray, a tray assembly, a battery pack assembly and a vehicle. The tray comprises a bottom plate and a frame, wherein the bottom plate comprises a plurality of sub bottom plates, runners are arranged in at least one part of sub bottom plates in the plurality of sub bottom plates, a battery module is suitably arranged on the sub bottom plates provided with the runners, and the frame is arranged at a peripheral edge of the bottom plate. By the tray, the volume requirement of a cavity for accommodating the battery module can be reduced, the runner arrangement is simpler, a water-cooling mode and an air-cooling mode can be simultaneously compatible, particularly in the water-cooling mode, a cooling liquid can directly flows outwards even the cooling liquid is leaked, short circuit of the battery module is prevented, the battery module is safer to use, and a relatively good protection effect can be played on the battery module.

Description

technical field [0001] The invention belongs to the technical field of vehicle manufacturing, and in particular relates to a tray, a tray assembly provided with the tray, a battery pack assembly provided with the tray, and a vehicle provided with the battery pack assembly. Background technique [0002] In the related art, the battery pack assembly of the vehicle is generally installed on a tray, and the tray and the outer cover jointly define a cavity for accommodating the battery assembly, and various cooling water channels or cooling air channels with complex structures are provided in the cavity. This structure requires The space of the cavity is large, and the cooling water channel and the cooling air channel are not compatible with each other, so the versatility is not strong, especially for the water-cooled structure, the wiring of the cooling water channel is complicated, and once a leak occurs, it is likely to cause a short circuit of the battery components.
