Title:
BATTERY LOWER CASE, BATTERY SYSTEM AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/008283
Kind Code:
A1
Abstract:
A battery lower case (1), a battery system and a vehicle. The battery lower case (1) comprises: a bottom plate (14); a plurality of fixed beams (11) sequentially connected end to end and fixed on the bottom plate (14); a cross beam (12) provided between the fixed beams (11) arranged in opposite; a support base (13) comprising a substrate (131) and limiting parts (132) which are connected to the substrate (131) and arranged in opposite, the substrate (131) and the oppositely arranged limiting parts (132) jointly define a groove (133), the substrate (131) is connected to the fixed beam (11), and an end portion (121), close to the fixed beam (11), of the cross beam (12) is embedded into the groove (133), so that the cross beam (12) can be connected to the fixed beam (11). According to the battery lower case (1), the support base (13) is provided between the fixed beam (11) and the cross beam (12), a substrate (131) of the support base (13) is connected to the fixed beam (11), the cross beam (12) is embedded into the groove (133) jointly defined by the substrate (131) and the oppositely arranged limiting parts (132), the collision impact force borne by the battery lower case (1) can be dispersed and weakened, the impact resistance of the battery lower case (1) is improved, then the damage degree in a battery system is reduced, and the safety and reliability of the battery system are improved.
