Between domain and head.
In a kind of above-mentioned aluminum cell pallet connection structure using the fixed battery modules of rivet nut, the staking
Nut deformation relief hole is located at rivet nut deformed region surrounding.
Compared with the prior art, the advantages of the utility model are:
1, batteries of electric automobile tray substrate is overcome to weld using with deformation relief hole rivet nut technique for fixing
The process difficulties of the offset of riveting point hole location caused by contraction distortion in journey, to influence the quality of battery tray or make workpiece
It scraps；
2, when common rivet nut of the staking deformed region without aperture being overcome to rivet at slot, since rivet nut deforms
Region material can not freely fill deformation in slot, support so that effective staking can not be formed on the parallel both sides of slot, therefore nothing
Method obtains the problem of effective installation bonding strength；
3, the patent can effectively overcome process difficulties of above two o'clock during aluminum cell case pallet production, be company's band
Carry out more economic benefit.
