Description

Technical Field

[0001] The utility model relates to the technical field of hybrid vehicle manufacturing, in particular to an assembled hoisting bracket for a hybrid vehicle battery compartment. Background Art

[0002] With the increasing popularity of new energy vehicles, in order to save operating costs and reduce pollution, more and more trailers are now designed as hybrid models. Hybrid vehicles need to install an engine and battery at the same time. The battery compartment is installed between the left and right beams of the hybrid vehicle through a lifting bracket. The current hybrid vehicle battery compartment lifting bracket is usually welded between the left and right beams of the hybrid vehicle. After being fixed, it cannot be adjusted and cannot adapt to various vehicle models and battery models. Secondly, due to the structural limitations of the left and right beams of the hybrid vehicle, when welding the lifting bracket, the operating space is small and the welding is difficult, which increases labor costs and the defect rate of the welds. In addition, the current battery compartment lifting bracket has no shock-absorbing function for the battery compartment. During the driving process of the trailer, it is bumpy and will cause certain damage to the battery. Utility Model Content

[0003] The purpose of the utility model is to provide an assembled lifting bracket for the battery compartment of a hybrid vehicle.
