Specific embodiment
Below against accompanying drawing, by the description to embodiment, specific embodiment of the present utility model is made detailed further
Thin explanation.
As shown in Figures 1 to 8, this batteries of electric automobile bag mounting structure, including a pair of sill strip 2, front apron sill 1
And rear floor front beam 3, front apron sill 1 is fixed on the front end of a pair of sill strip 2, and rear floor front beam 3 is fixed on one
Rear end to sill strip 2, a pair of sill strip 2, front apron sill 1 and rear floor front beam 3 are formed for installing fixing electricity
The frame structure of Chi Bao, is provided with floor in frame structure, battery bag is located at the lower section on floor.
A pair of sill strip 2, front apron sill 1 and rear floor front beam 3 are the aluminium profile structure of hollow, an opposite house
It is aluminum section bar frame that sill beam, front apron sill and rear floor front beam are formed for the frame structure installing self-contained battery bag
Structure, aluminium section bar passes through mould extrusion molding, and weight is little, and structural strength is big, is conducive to electric automobile lightweight, can effectively extend
Electric automobile course continuation mileage.
The inside of a pair of sill strip 2, front apron sill 1 and rear floor front beam 3 is equipped with nutplate mounting bar
203, the battery on nutplate mounting bar installs nutplate 204, the bottom of sill strip, front apron sill and rear floor front beam
The screw that on plate, nutplate installed by corresponding battery is equipped with corresponding through hole.
Battery installation nutplate is provided with the project-welding nut for self-contained battery bag, and nutplate mounting bar is provided with and projection welding
The corresponding hole of the screw of nut, nutplate mounting bar is aluminium sheet structure, and nutplate installed by battery is steel plate structure, structure design
Rationally, lightweight, structural strength simultaneously can meet requirement.
Nutplate installed by battery is that a Battery pack installs nutplate, and a Battery pack installs the setting of nutplate uniform intervals, is subject to
Power is uniform.
Battery installs that nutplate is dismountable is located on nutplate mounting bar.Preferably, nutplate mounting bar is provided with one
To clamp, battery is installed nutplate and is stuck in a pair of clamp.The distance between a pair of clamp bottom is more than battery and installs nutplate
Length, the distance between a pair of clamp upper end be less than battery install nutplate length.
It is equipped with for one group of separate chamber will be separated in beam in sill strip, front apron sill and rear floor front beam
The reinforcement of body.Draw-in groove, nutplate mounting bar are equipped with the base plate of sill strip, front apron sill and rear floor front beam
It is inserted in draw-in groove.
Bolt on battery bag framework is installed the screw in nutplate with battery and is matched, and battery is fixed, each
Beam entirety stress, uniform force, relatively conventional single-side stand is fixed, and battery fixation is more reliable.And whole Battery pack installation structure
In each beam hollow cavity, it is not take up space outerpace, convenient installation.
