As optimization, it is in labyrinth that the welding bar in region at left and right sides of hinge is located on air bag installing frame along hinge width direction
Formula distribution.
Such, such distribution mode is conducive to the exhaust of the region welding bar.
It is located at left and right sides of hinge as optimization, on the air bag installing frame and offers at the center in region for positioning
The positioning through hole of air bag installing frame and Welding jig, the positioning through hole are elongate holes.
Such, air bag installing frame and being welded and fixed for instrument board are carried out by Welding jig, air bag installing frame
Fixed to then positional relationship between the two is positioned by location hole on Welding jig, prevent positioning inaccurate to cause welding matter
Amount is low, positioning through hole be elongate holes be in order to correspond to strip boss on Welding jig and match.
As optimization, the air bag installing frame, air bag cover plate and hinge are made of thermoplastic polyurethane elastomer material.
It is such, air bag installing frame, air bag cover plate and hinge are conducive to using thermoplastic polyurethane elastomer material and protected
While demonstrate,proving intensity, it can also be ensured that the suppleness that hinge needs when overturning.
As optimization, the annular boss height is 1.2mm, and welding bar height is 2.5mm.
Such, during actual welding, the welding capacity of welding bar and instrument board is 1mm, welding bar after the completion of welding
Height be 1.5mm, guarantee also to be greater than the height of annular boss to prevent annular boss together with instrument board fusion weld.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the cross-sectional view in the direction A-A in Fig. 1.
Specific embodiment
Below with reference to example attached drawing, the utility model is described in further detail.
When specific implementation: referring to Fig. 1 to Fig. 2, a kind of airbag door, including middle part be provided with opening air bag installing frame 1,
It is covered on the air bag cover plate 2 of 1 opening of air bag installing frame and connects the air bag installing frame 1 and the air bag cover plate 2
Hinge 3, multiple welding bars 4 being used to and instrument board is welded and fixed are distributed on the air bag installing frame 1 and air bag cover plate 2,
At least one through-hole 5 is offered in each welding bar 4,5 outer ring of through-hole is provided with for stopping welding residue to fall into through-hole 5
Annular boss 6, the height of the annular boss 6 is lower than the height of welding bar 5.
It is such, by the way that annular boss 6 is arranged in 5 outer ring of through-hole, through-hole 5 is allowed both can to play gas vent in injection phase
Effect, and welding slag can be stopped to flow into through-hole 5 in the stage that is welded and fixed and block hole location, it is convenient to protrude into through-hole 5 by slide calliper rule
Middle measurement welding capacity detects the depth of weld, to improve the accuracy of Welding quality test, realizes the dual-purpose effect in a hole.
When implementation, multiple welding bars are distributed along the length direction parallel interval of hinge.
Such, welding bar is distributed in this way to be conducive to weld with instrument board, not will cause concentration welding so that part connects
Loosely.
When implementation, multiple parallel reinforcing ribs 7 for being used to reinforce 2 intensity of air bag cover plate are provided on the air bag cover plate 2,
Each reinforcing rib 7 is vertical with the welding bar 4 on air bag cover plate 2 and intersects.
Such, reinforcing rib 7, which is arranged, and intersects vertically with welding bar 4 can reinforce the intensity of air bag cover plate 2.
When implementation, the height of the reinforcing rib 7 is lower than the height of the welding bar 4 on air bag cover plate 2.
Such, since the welding bar 4 on air bag cover plate 2 will be welded with instrument board, the height of reinforcing rib 7 is than welding bar 4
Height it is low be conducive to welding bar 4 individually with instrument board weld, will not be soldered together with reinforcing rib 7.
As optimization, the height of the reinforcing rib is 1.5mm, and welding bar height is 2.5mm.
Such, during actual welding, the welding capacity of welding bar 4 and instrument board is 1mm, welding bar after the completion of welding
4 height is 1.5mm, also prevents reinforcing rib 7 together with instrument board fusion weld when guaranteeing the intensity of reinforcing rib 7.
When implementation, 5 part of through-hole is located at 4 intersection of welding bar on reinforcing rib 7 and air bag cover plate.
Such, such distribution mode is conducive to the exhaust of injection phase welding bar 4, intersects in 7 welding bar 4 of reinforcing rib
Place is provided with through-hole 5 while being conducive to the exhaust of reinforcing rib 7 and welding bar 4.
When implementation, the welding bar 4 on air bag installing frame 1 positioned at 3 left and right sides region of hinge is along hinge width direction in fan
The distribution of palace formula.
Such, such distribution mode is conducive to the exhaust of the region welding bar.
When implementation, offered at the center in 3 left and right sides region of hinge for positioning on the air bag installing frame 1
The positioning through hole 8 of air bag installing frame 1 and Welding jig, the positioning through hole 8 are elongate holes.
Such, air bag installing frame 1 and being welded and fixed for instrument board are carried out by Welding jig, air bag installing frame
1 is fixed on Welding jig the then positional relationship by the positioning of positioning through hole 8 between the two, prevents positioning inaccurate to cause to weld
Connect poor quality, positioning through hole be elongate holes be in order to correspond to strip boss on Welding jig and match.
When implementation, the air bag installing frame 1, air bag cover plate 2 and hinge 3 are by thermoplastic polyurethane elastomer material system
At.
It is such, air bag installing frame 1, air bag cover plate 2 and hinge 3 are conducive to using thermoplastic polyurethane elastomer material and existed
While proof strength, it can also be ensured that the suppleness that hinge 3 needs when overturning.
When implementation, 6 height of annular boss is 1.2mm, and 4 height of welding bar is 2.5mm.
Such, during actual welding, the welding capacity of welding bar 4 and instrument board is 1mm, welding bar after the completion of welding
4 height is 1.5mm, guarantees the height for being also greater than annular boss 6 to prevent annular boss 6 and instrument board fusion weld one
It rises.
