Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
As shown in Figures 1 to 7, the electric car sill strip, including sill strip ontology 2, sill strip ontology both ends respectively with A
Column flowering structure 1 and B column 3 are connected, wherein sill strip ontology 2, A column flowering structure 1, B column 3 are hollow aluminium profile structure, weight
Small, structural strength is big, is conducive to electric car lightweight, can effectively extend electric car course continuation mileage.
The battery fixing structure for fixing battery is equipped with inside sill strip ontology 2.Battery fixing structure is arranged in threshold
Beam body interior, relatively tradition are arranged in sill strip body exterior, and stable structure is reliable, and saves sill strip lower space.
The reinforcing rib for sill strip body interior to be divided into one group of cavity is equipped in sill strip ontology 2.Battery is fixed
Structure is located in the cavity of sill strip ontology bottom, that is, is mounted on the bottom plate of sill strip.
2 top of sill strip ontology is equipped with hollow protrusion, and protrusion is structure as a whole with sill strip ontology.Sill strip ontology
Both ends are equipped with sealing plate, and sealing plate is respectively preceding sealing plate 207 and rear sealing plate 206, and two sealing plates are aluminium sheet, and weight is small.
Sill strip ontology one end is connected with A column flowering structure, and the sill strip ontology other end is connected with B column, A column flowering structure and B
The lower end of column is stuck in protrusion, and is connected by welding, and connection is reliable.The protrusion of sill strip ontology is equipped with lower part seam allowance,
And raised one end is located at equipped with the seam allowance connecting plate 201 for being connected with the side seam allowance in A column flowering structure, improve the structure of seam allowance
Intensity.
