Description
Technical field
This utility model belongs to technical field of automobile parts and in particular to a kind of lightweight automobile rear bumper.
Background technology
With the development of the light-weight design of automobile, the light-weight design for product component is product design at this stage
Direction, because the both direction that product light-weight design is mainly relied on is material and process structure, mainly examining for material
Consider the factor having the aspects such as production cost, material capability and recycling, what process structure was mainly in view of be technology difficulty,
The factor of the aspects such as structural stability, because overall development is not perfect in light-weight design at this stage, therefore, for product
Structural behaviour and the design of process structure also there is many deficiencies.
Utility model content
The purpose of this utility model is for above-mentioned problem and shortage, provides a kind of reasonable in design, compact,
Process structure is stable, entirely using the lightweight automobile rear bumper of thermoplastic one molding.
Adopted the technical scheme that by reaching above-mentioned purpose：
A kind of lightweight automobile rear bumper, including rear bumper body, is arranged on two ends about rear bumper body
Bumper side plate and the lower baffle plate being arranged on rear bumper body bottom portion, are provided with U-type groove on the upside of described rear bumper body,
Technology groove is offered on rear bumper body, described technology groove includes the bar shape trench hole positioned at middle part and is located at bar shape trench hole two
The reflector installing hole in inverted trapezoidal at end, described rear bumper body, bumper side plate and lower baffle plate are thermoplastic composite
Material one compression molding, and seamlessly transit for arc between three, it is provided with the inner side of rear bumper body and hand in cross
The energy-absorbing rib of fork distribution, the infall of energy-absorbing rib is provided with energy-absorbing post, is embedded with nut in wherein at least two energy-absorbing post
Inserts, is provided with ring stiffener, energy-absorbing rib and ring stiffener one compression molding in rear bumper inside circumference, and
Form energy-absorbing chamber between energy-absorbing rib and ring stiffener.
It is provided with two connection otic placodes inside described lower baffle plate.
It is provided with ring stiffener inside technology groove.
Using technique scheme, acquired beneficial effect is：
This utility model reasonable in design, compact, its by integral die design is carried out using thermoplastic, not only
It is easy to plastify machine-shaping, stable mechanical property, recoverable, whole process structure is stable simultaneously, energy under stress effect
Enough effectively realize energy-absorbing function, ensure the strength character of whole product；This utility model design freedom is big, and chemically-resistant is resistance to
Corrosive nature, processing leftover bits and damaged waste product can recycle, and do not result in the pollution of environment, can effectively save
About production cost, meets the policy of automotive light weight technology design.
