Description
Technical field
The utility model belongs to new-energy automobile technical field, especially relates to a kind of rotational-molded automobile chassis.
Background technology
In recent years, electronlmobil industry has obtained developing rapidly, the vehicle body of current electronlmobil is generally glass-felt plastic or sheet metal material, chassis all adopts metal construction, the weight of the automobile of this structure self is heavier, the shortcomings such as the flying power to automobile has considerable influence, and the shock resistance of automobile is poor, and safety factor is low.A lot of research is being done by more domestic producers aspect the lightweight of auto body, as mentioned a kind of three-layer plastic automobile case of disposal molding in disclosed patent (CN102601905A), this plastic casing has the advantages such as the light and shock resistance of quality is good, but the domestic plastifying technology about car chassis is innovated seldom.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and provides a kind of by car chassis disposal molding, reduces production process, reduces production costs; Alleviate the weight of automobile, reduce energy consumption; Improve the impact strength of automobile; Improve the rotational-molded automobile chassis of the soundproof effect of automobile.
The purpose of this utility model solves by following technical proposal:
A kind of rotational-molded automobile chassis, comprise chassis main body, it is characterized in that: described chassis main body comprises top layer and center foaming layer, described top layer comprises endosexine and uppermost layer, between uppermost layer and endosexine, be provided with cavity, in the cavity of described center foaming layer between uppermost layer and endosexine; Described chassis main body is provided with for strengthening reinforcing rib structure and the kiss formula structure of rigidity and intensity, also includes location structure in the main body of chassis, and described location structure is provided with the mounting hole site fixing with vehicle body.。
Chassis described in the utility model location structure is concavo-convex slot type structure.
The uppermost layer of chassis described in the utility model main body and endosexine are that the material of uppermost layer and endosexine is crosslinked polyethylene by the one-time formed hollow plastic product of rotational molding technique, and degree of crosslinking reaches more than 60%.
In the uppermost layer of foaming layer Wei in center described in the utility model chassis main body and the cavity between endosexine, add disposable expanded material rotational moulding and form, middle foaming layer is LLDPE foamed material.
The wall thickness of endosexine described in the utility model and uppermost layer is 5-8mm, and the spacing between kiss formula structure and kiss formula structure is 2-2.5 times of top layer plastics wall thickness.
Compared to the prior art the utlity model has following characteristics and beneficial effect:
1, adopt roll moulding shaping technology by car chassis disposal molding, reduce production process, reduce production costs.
2, between uppermost layer and endosexine, disposal molding middle foaming layer alleviates the weight of automobile, reduces energy consumption.
3, middle foaming layer has strengthened rigidity on the one hand, has increased on the other hand the effect of the energy-absorbing of car chassis, reduce and impact, and the soundproof effect of automobile can be better.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cutaway view.
Fig. 3 is that the utility model is looked up structural representation.
