Description

Technical Field

[0001] The utility model relates to the technical field of rack-mounted structures, and specifically relates to a pick-up structure on both sides of an assembled hybrid vehicle battery compartment. Background Technique

[0002] A hybrid vehicle refers to a vehicle that is equipped with both an internal combustion engine and an electric motor to achieve more efficient energy utilization and reduce emissions. The battery compartment of a hybrid vehicle is usually used to store high-voltage battery packs, and these battery packs provide power for the electric motor. In order to install, fix, and protect the battery packs, the battery compartment is integrated into the pick-up structure.

[0003] At present, the connecting parts between the pick-up structures on both sides are mostly single or single-layer structural parts, resulting in low connection stiffness and strength. It is very easy to collapse and deform when being impacted, and then the battery compartment is easily squeezed. After the battery compartment is squeezed, it is prone to spontaneous combustion, and there are certain potential safety hazards. Content of the Utility Model

A plurality of through holes for reducing their respective weights are opened on all these load-bearing components. In order to reduce the weight of each load-bearing component, a plurality of through holes for reducing their respective weights are opened on all the load-bearing components, thereby carrying out lightweight treatment on the entire hoisting structure.

[0058] As Figures 1 to 2As shown, all the detachable fixed installation methods in the two-side battery compartment frame assembly 1 and the middle strengthening connection assembly 2 are the installation by the cooperation of bolts and nuts (the installation of bolts and nuts is omitted in the figure to ensure the clarity of the drawing). In order to realize the disassembly and installation of each structural member, the traditional installation by the cooperation of bolts and nuts is used to ensure smooth disassembly during subsequent maintenance or repair.
