Abstract
The utility model discloses a kind of weakening structure of automotive trimming door plate handrail, including door panel arm rest skeleton, the hand facings of the door panel arm rest skeleton is provided with some staggered cross-holes, the long axis direction of the cross-hole is the fore-and-aft direction of vehicle, the single cross-hole area accounts for the hand facings gross area 5~6%, and the gross area of the cross-hole accounts for the hand facings gross area 55~80%.The weakening structure of the automotive trimming door plate handrail can be when side impact occurs for vehicle, it is easier to carries out crumple, ensures passenger safety.
Description
Technical field
A kind of weakening structure of automotive trim is the utility model is related to, more particularly to a kind of automotive trimming door plate handrail
Weakening structure.
Background technology
Auto industry is quickly grown, and vehicle safety has become an important indicator for considering automotive performance.Automobile
In terms of security is mainly reflected in the security configuration of automobile, including gas-bag system, the electronic system related to vehicle safety, collision
Performance etc..In vehicle collision test, usually collapsing to absorb Impact energy using vehicle part itself, mitigates to passenger's
Impact.Therefore in vehicle is related to, the corresponding weakening structure of generally use, it is made to be deformed rapidly in collision.Typically in air bag
In system, inside gadget corresponding to balloon positions needs to be weakened, and breaks through inside gadget in time when being ejected so as to air bag.Existing vapour
The weakening structure of in-car decorations door panel arm rest typically using laser or cold brill milling reduction, opens up in the hand lining position of interior trim door-plate skeleton
Transverse concave groove, but too deep its of groove is difficult to ensure that enough support strengths, groove is excessively shallow and easily crushes generation in collision
Cutting edge, security threat is produced to passenger.
Utility model content
The defects of for above-mentioned prior art, the utility model provide a kind of reduction knot of automotive trimming door plate handrail
Structure, solves the problems, such as existing automotive trimming door plate handrail security deficiency.
Technical solutions of the utility model are as follows：A kind of weakening structure of automotive trimming door plate handrail, including door panel arm rest bone
Frame, the hand facings of the door panel arm rest skeleton are provided with some staggered cross-holes, the long axis direction of the cross-hole
For the fore-and-aft direction of vehicle, the single cross-hole area accounts for the hand facings gross area 5~6%, the cross-hole
The gross area accounts for the hand facings gross area 55~80%.
Further, it is provided with recessed curved surface in cross-hole region in the hand facings.
Preferably, minimum range of the cross-hole apart from the front side edge edge of hand facings is 2~10mm.
Preferably, minimum range of the cross-hole apart from the left and right sides edge of hand facings is 2~10mm.
Preferably, the cross-hole is 10~40mm apart from the minimum range of the rear lateral edge of hand facings.
Preferably, the major axis of the cross-hole and short axle ratio are 3~4 ︰ 1.
The advantages of technical scheme provided by the utility model, is：The weakening structure of the automotive trimming door plate handrail is one
As in the case of enough support strengths can be provided；When side impact occurs, extruding can be rapidly formed between hand facings cross bore and is become
Passenger safety is protected in shape, easy crumple.Other cross pore structure has saved skeleton materials while proof strength.Hand facings
Curved surface be easy to the installation of foaming block to position.
Brief description of the drawings
Fig. 1 is the weakening structure schematic diagram of automotive trimming door plate handrail.
Fig. 2 is hand facings region schematic top plan view.
Embodiment
With reference to embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Incorporated by reference to shown in Fig. 1, Fig. 2, the weakening structure of the automotive trimming door plate handrail involved by the present embodiment, including door-plate
Armrest skeleton 1, foaming block and corresponding epidermis are attached on door panel arm rest skeleton 1.Door panel arm rest skeleton 1 is included in front end
Handle portion 2 (not completely shown), the breach 3 positioned at the upside of handle portion 2 and the hand shirt portion point positioned at the rear side of handle portion 2
4, wherein breach 3 is used to install switch panel, and hand shirt portion point 4 is used to support passenger's elbow.The face of passenger's elbow is supported to be served as a contrast for hand
Face 5.
Hand facings 5 is provided with some staggered cross-holes 6, and the long axis direction of cross-hole 6 is the front and rear of vehicle
Direction, the single area of cross-hole 6 account for the gross area 5~6% of hand facings 5, and it is total that the gross area of cross-hole 6 accounts for hand facings 5
Area 55~80%.Recessed curved surface 7 is provided with the region of cross-hole 6 in hand facings 5, as shown in figure 1, recessed curved surface 7 is in
Spoon is pointed, and it is corresponding with foaming block, is mainly used in preventing foaming block from sliding in hand facings 5, in order to foaming block
Installation.
Incorporated by reference to shown in Fig. 2, in the present embodiment, minimum range d1 of the cross-hole 6 apart from the front side edge edge of hand facings 5 is
2~10mm.Minimum range d2 of the cross-hole 6 apart from the left and right sides edge of hand facings 5 is 2~10mm.The distance of cross-hole 6
The minimum range d3 of the rear lateral edge of hand facings 5 is 10~40mm.The 1 long 24mm of longitudinal axis L of cross-hole 6, short axle L2 length 6~
8mm.Apply the pressure 222N of the normal direction of hand facings 5 in the a-quadrant shown in Fig. 2, maximum moulding strain caused by it is
4.9%, fully meet the support requirement of elbow.
