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 4, the electric car front windshield lower beam, including front windshield lower beam ontology 1, under front windshield
Cross-beam body 1 is hollow aluminium profile structure, and structure 3 and A column are tied up and down on the end of front windshield lower beam ontology 1 and A column
Structure attachment beam 4 is connected.
A column up-down structure attachment beam 4 is the longitudinal beam connected for connecting structure 3 and A column flowering structure 5 on A column, A column up-down structure
Attachment beam rear end is welded in A column flowering structure, and the front end of structure is welded on A column up-down structure attachment beam front end upper surface on A column
On, the end face of structure front end is plane on A column.During structure and A column flowering structure and A column up-down structure attachment beam be on A column
Empty aluminium profile structure.Aluminium profile structure is by mold extrusion molding, and weight is small, and structural strength is big, and both collision and weight can
To combine, and be conducive to electric car lightweight, can effectively extend electric car course continuation mileage.
It is equipped in A column flowering structure 5 for the reinforcing rib by A -pillar structure inside division at one group of cavity, light-weight, guarantee knot
Structure intensity.Reinforcing rib is criss-cross construction, i.e. a cross reinforcing, a waling, the shape inside A column flowering structure
At four cavitys, i.e., it is in the inner part two cavitys inside A column flowering structure, is in the outer part two cavitys, guarantees the same of structural strength
When there is certain energy-absorbing effect, there is preferable central collision and side impact effect, structural strength is big, can be under top attachment beam and front windshield
Crossbeam provides secure support.
The lower part of front windshield lower beam ontology 1 is connected with gutter channel rear portion 2, and gutter channel is aluminum component structure, i.e. aluminium sheet structure.
Gutter channel rear portion 2 is equipped with one group of reinforcing rib, and length direction and the front windshield lower beam ontology cross central line of reinforcing rib mutually hang down
Directly, reliable support is formed to front windshield lower beam ontology, light-weight, structural strength is big.
Front windshield lower beam ontology 1 is equipped with front windshield joint face 101, and front windshield joint face is skew surface, passes through glass
Glue is connected with front windshield, and the lower edge of front windshield joint face is equipped with protrusion, is easily installed.
1 end of front windshield lower beam ontology is equipped with the side protrusion for being stuck on A column in structure inner side step, side protrusion
It being matched on lower part and the upper surface of A column up-down structure attachment beam, A column up-down structure attachment beam forms reliable support, and
Front windshield lower beam ontology end face lower part is connected with front wall side board 6, reasonable in design, and connection is reliable.
Front windshield lower beam ontology 1 is equipped with instrument assembly mounting surface 102, and instrument assembly mounting surface is equipped with mounting hole,
The installation nut 103 for fixed instrumentation assembly is equipped in mounting hole.
Preferably, it is equipped with double wedge at installation nut and front windshield lower beam body fits, double wedge is embedded in front windshield lower beam
In ontology, installation nut not can rotate with respect to front windshield lower beam ontology, easy for installation, prevent the later period from installing nut loosening, shadow
Fixed effect is rung, abnormal sound is generated.
Alternatively, front windshield lower beam is set inside the body card slot, i.e. the card slot inside that is located at instrument assembly mounting surface, card
Nut strip is inserted in slot, nut strip is equipped with installation nut, and installation nut is project-welding nut, the nut bore and installation of project-welding nut
Hole is corresponding.Both ends are fixed on front windshield lower beam ontology by rivet in nut strip insertion card slot, and structure is simple, installation behaviour
Make easy；And project-welding nut is not easy to loosen, and due to traditional single mounting hole stress, is changed under entire nut strip and front windshield
Cross-beam body stress, uniform force, instrument assembly fixation is more reliable, and front windshield lower beam ontology is unlikely to deform.
