Skill problem；Overcome the material of common rivet nut staking deformed region Free Transform can not fill in slot in staking deformation
So as to cause the problem of installation staking bonding strength deficiency.
The present invention solves technical solution used by above-mentioned technical problem：A kind of rivet nut, it is characterised in that：Including
There is main body, the main body is hexagonal structure or circular configuration, has staking deformed region in main body, in the deformed area of main body
Domain is provided with the relief hole that can make material Free Transform.
In a kind of above-mentioned rivet nut, the deformed area is more lateral ribs for being arranged in main body periphery,
Relief hole is deformed to be on lateral rib.
In a kind of above-mentioned rivet nut, the main body is made of head and bar portion, and bar portion is divided into staking deformed area
Domain and threaded portion, the deformed region is between threaded portion and head.
A kind of aluminum cell pallet connection structure using the fixed battery modules of rivet nut, which is characterized in that battery tray
Rivet nut is installed on floor structure.Rivet nut includes main body, and the main body is six-sided structure or cylindrical structure, master
There is staking deformed region on body, material deformation relief hole, the battery tray bottom plate are provided on the deformed region of main body
On open up grooved hole, rivet nut pass through make after slot staking is deformed battery modules and battery tray bottom plate connect with it is tight
Gu.
In a kind of above-mentioned aluminum cell pallet connection structure using the fixed battery modules of rivet nut, rivet nut exists
When staking deforms in slot, due to the presence of slot in deformed region, allow the material of deformed region free in deformation
Deformable filler slot.The parallel both sides of the slot and deformed region form effective staking support so that battery modules and battery
Tray substrate connection and fastening.
In a kind of above-mentioned aluminum cell pallet connection structure using the fixed battery modules of rivet nut, the slot
Shape be round, ellipse or polygon.
In a kind of above-mentioned aluminum cell pallet connection structure using the fixed battery modules of rivet nut, the staking
Nut main body is made of head and bar portion, and bar portion is divided into deformed region and threaded portion, and the deformation position is in threaded portion
Between 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 present invention are as follows：
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.
