Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples.
As shown in Figure 3 and Figure 4, inner panel windowsill stiffening plate structure 1 of the present invention is set to 3 lower frame of windowsill and fixes in inner panel 2
Connection, including protrusion platform terrace 11, the upper welding edge 12 extended from the protrusion platform terrace 11 toward 3 direction of windowsill, from described convex
Step surface 11 extends toward 3 opposite direction of windowsill out lower welding edge 13 and 11 two sides of protrusion platform terrace and the inner panel 2 is fixed connects
The side plate 14 connect, it is characterised in that: the lower welding edge 13 is zigzag, and the every toothed rack of the lower welding edge 13 is equipped with and institute
The solder joint of the welding of inner panel 2 is stated, the lower 13 rest part trimming of welding edge and the inner panel 2 are from sky.
Such structure only overlaps in the position of arrangement solder joint and inner panel 2, is apparent from welding position when worker can be allowed to weld
It sets, improves the stability of welding, work task efficiency is provided；Part loss of weight is given simultaneously, reduces cost.Lower welding edge 13 remaining
Part trimming and inner panel 2 enable electrophoresis liquid can smoothly enter into from sky, solve cannot be introduced into electrophoresis liquid cause can not antirust ask
Topic, loss of weight enhance rustless property simultaneously, improve the band Line stiffness of inner panel 2.
The protrusion platform terrace 11 is vertically arranged, parallel with inner panel 2, and lower 13 Z-direction of welding edge is preferably dimensioned to be
13mm ~ 15mm increases the cavity body structure of inner panel 2 Yu inner panel windowsill stiffening plate structure 1, further mentions compared with prior art
Strip Line stiffness in height.
The upper welding edge 12 is also configured as zigzag, and upper 12 rack gear of welding edge is equipped with to be welded with the inner panel 2
Solder joint, be made into zigzag, only arrangement solder joint position and inner panel 2 overlap, welding is apparent from when worker can be allowed to weld
Position, improves the convenience of worker's welding, and working efficiency improves；And electrophoresis liquid is enabled smoothly to flow into and be discharged, loss of weight is same
Shi Zengqiang rustless property.
The protrusion platform terrace 11 is equipped with lightening hole 112, can also first be equipped with concave surface 111 in protrusion platform terrace 11, described
Lightening hole 112 is set again on concave surface 111.The positive pressing direction of the protrusion platform terrace 11 rise lightening hole 112 so that inner panel 2 with
The air of cavity can be discharged between inner panel windowsill stiffening plate structure 1, and electrophoresis liquid can be substantially adhered to metal plate housing surface, mention
The rustless property of high part, while giving part loss of weight.
The concave surface 111 extends along 11 length direction of protrusion platform terrace, and the averagely layout of lightening hole 112 is described
On concave surface 111, preferably described 111 bottom surface of concave surface is identical as the size of lightening hole 112, increases by 11 entirety of protrusion platform terrace in this way
Rigidity.
The quantity of the lightening hole 112 is at least 2, be arranged because of stiffening plate structure of the present invention generally strip more
Several lightening holes 112 can make the air of cavity be smoothly discharged, and electrophoresis liquid can be substantially adhered to metal plate housing surface, improve
The rustless property of part, while giving part loss of weight.
Arrangements for automotive doors of the present invention includes above-mentioned inner panel windowsill stiffening plate structure 1, further includes windowsill 3 and inner panel 2, between three
