December) it is not less than the plastic material of 7GPa, preferably effective homogeneity stretch modulus is the plastic material of 8-10GPa.In satisfaction
The conventional plastic material for stating requirement includes polypropylene PP, the nylon PA material enhanced containing fiber (such as glass).Selection is conventional
Plastic material has cost advantage, but has lost properties of product, it is therefore desirable to make up performance loss by product structure.Such as Fig. 6
Shown, upper and lower wing plate 12,13, spacing board 14, cross bar 4 and the first reinforcing plate 5 are from 11 outwardly extending length of the first support plate
No more than 70mm.Similarly, forward and backward wing plate 16,17, spacing board 14, cross bar 4 and the second reinforcing plate 6 from the second support plate 15 to
The length of outer extension and left and right wing plate 22,23, spacing board 14, cross bar 4 and third reinforcing plate from third support plate 21 to
The length of outer extension is likewise not greater than 70mm.All support plates 11,15,21 and all wing plates 12,13,16,17,22,23
Wall thickness is not less than 2.0mm, and the minimum thickness of all reinforcing ribs 4 is at least 1mm.The above design, by increasing parts profile size,
The problem using conventional material performance deficiency is compensated for, while reducing material cost again.Compared to relatively with money steel instrument board cross
Beam, weight saving 25% or more, while also reducing the difficulty of mold design processing and manufacturing equipment technique.
Fig. 3, Fig. 5, Fig. 7 and Fig. 9 are referred to again, and instrument board plastics crossbeam assembly C further includes the interconnecting piece being connect with main body 1
P, because of the limitation of mold, the interconnecting piece P at the both ends or side that are connected to main beam 1 is the unilateral groove profile knot of outward opening
Structure, and cross bar 4 is equipped in the trench structure, transversely or longitudinally to reinforce connecting.Interconnecting piece P can with ontology one at
Type separately formed can also form instrument board plastics crossbeam assembly C, in Fig. 3 by being welded or bolted on ontology again
Shown in bulk-breaking plastics small rack 3.Instrument board plastics crossbeam assembly C passes through the metal connection point that is arranged on interconnecting piece P, such as U
Type inserted sheet nut U or bolt S, to be connect with other electrical parts (such as instrument, air-conditioning, steering column etc.).
Except of course that the embodiment of instrument board plastics crossbeam assembly C described above, can also according to each vehicle to assembly,
The scheme of plastics crossbeam is locally changed in the actual demand of local strength, such as shown in figure 11, instrument board plastics crossbeam assembly C's
The structure of ground connection vertical beam is substituted by steel bracket G, and steel bracket G is bolt-connected on plastics main body of cross-beam, to adapt to
Instrument board plastics crossbeam assembly C assembles the demand got on the bus.
Above-described, only presently preferred embodiments of the present invention is not limited to the scope of the present invention.The present invention's is upper
Stating embodiment can also make a variety of changes, for example the above-mentioned overall plastic crossbeam of automotive trim instrument board is the modeling of automotive trim instrument board
Expect one kind in crossbeam type, other are such as locally increasing some small metallic supports or other materials part to host plastic
Also the function and purpose of such instrument board plastics crossbeam technical solution can be realized on crossbeam.I.e. every power applied according to the present invention
Simple, equivalent changes and modifications made by sharp claim and description fall within the claim protection of patent of the present invention
Range.The not detailed description of the present invention is routine techniques content.
