Accompanying drawing explanation
Fig. 1 is a kind of bumper for automobile example structure schematic diagram in this utility model.
Detailed description of the invention
This utility model is in order to solve the problems referred to above, it is provided that a kind of bumper for automobile.
For reaching above-mentioned purpose, this utility model by the following technical solutions:
A kind of bumper for automobile, including:
Main thick stick body 1, shell 2, backplate 3, decoration 4, car puller hook 5, connection sheet 6 and carbon steel draw code 7；
Main thick stick body 1 surface is designed with some grooves and circular hole, and groove can increase the physical bond power of shell 2 and main thick stick body 1, and polyurethane, when foaming, forms I-shaped by the circular hole of main thick stick body 1 and connects so that shell 2 and main thick stick body 1 compact siro spinning technology.
It should be noted that, shell 2 is the polyurethane of 0.45-0.5g/cm3 density foaming, it passes through foam process integral coating in the outer surface of main thick stick body 1, thickness is 5-7mm, appearance is erosion stricture of vagina effect, shell 2 epidermis has leather texture, soft elastic tactility, and has certain collision energy-absorbing effect.Use high density expanded polypropylene Replacing engineering plastics or metallic framework, significantly reduce the weight of product；Engineering plastics are according to the difference of material, its proportion substantially is between 0.9-1.5g/cm3, wherein the cost performance with polythene material is the highest, its proportion is 0.94g/cm3, and EPP is directly affected by expansion ratio, and expansion ratio is from 5-30 times, the density definition more than 0.03g/cm3 is high density EPP, calculating with 5 times of expansion ratios that density is maximum, the proportion of the most foamed pp material is 0.9g/cm3, and after 11 times of foaming, the computational methods of proportion are: 5 times=0.18g/cm3 of 0.9g/cm3 ÷.It follows that the proportion of 5 multiplying power expanded polypropylenes is only the 1/5 of polyethylene；For the 1/15 of aluminum material (2.7g/cm3), for the 1/43 of carbon steel (7.8g/cm3)；As a example by Bumper product, the weight using polyethylene hollow blow molding structural framework is 2.2kg, and uses the weight of 5 multiplying power expanded polypropylenes to be only 0.8kg, weight reduction 63.6%；
Polyethylene heat distortion temperature is 50-60 degree, and expanded polypropylene heat distortion temperature is 120 degree, and the foam process temperature of polyurethane is 50-60 degree, moment can reach 100 degree, relative to using vinyon skeleton, EPP has higher heat-resistant deforming temperature, and product size is more stable；
Backplate 3 is engineering plastics injection mo(u)lding, and surface is electrodeposited chromium or spray silver paint effect, and the design of big backplate makes product entirety more high-end and atmospheric, and product is integrated with certain support setting effect, prevents deformation of products；
Decoration 4, is installed on the both sides of described main thick stick body 1 by connecting sheet 6.
Car puller hook 5 one end is installed on main thick stick body 1, and the other end fixes the installation position locking onto vehicle；
Described carbon steel draws code 7 one end to be installed on main thick stick body 1, and the other end is fixing with automobile body to be connected；
Described backplate 3 arranges net surface structure 8.
Optionally,
The material of described car puller hook 5 is that nylon+30% glass fibre injection mo(u)lding substitutes carbon steel.
Glass fibre injection mo(u)lding substitutes carbon steel, carbon steel needs stamped, welding fabrication, for improving antiseptic property, also need to carry out application process, complex procedures, relatively costly, employing nylon+30% glass fibre can be with the parts of once injection moulding required form, and after molding, it is made without rear surface process, significantly simplify operation, reduce cost；Carbon steel proportion is 7.8g/cm3, and the proportion of nylon+30% glass fibre raw material is about 1.35g/cm3, alleviates the weight of product.
Optionally,
The material of described connection sheet 6 is that nylon+20% glass fibre injection mo(u)lding substitutes carbon steel.
Optionally,
Described shell 2 is the urethane skins of 0.45-0.5g/cm3 density foaming, by foam process integral coating in the outer surface of main thick stick body 1.Nylon+20% glass fibre injection mo(u)lding substitutes carbon steel, alleviates again, reduces cost.
The above, above example only in order to the technical solution of the utility model to be described, is not intended to limit；Although this utility model being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of this utility model each embodiment technical scheme.
