Background technology
Reflex Reflector is called reflecting piece, reflector or reflective lattice, be usually used in automobile, motorcycle, bicycle it is anti-
Light or passive light source part.As automobile lamp, it is usually mounted to the tail portion of automobile.The structure of Reflex Reflector is simple, usually
Only two components of lampshade and shell mainly carry out " it is reflective that excuse me " using the decorative pattern of lampshade inner surface, driver are enable to see
To the light that bounce back comes from the Reflex Reflectors for Automobiles of front, to take deceleration appropriate or measures to keep clear.It is made in production
During making, lampshade and shell are bonded together by lampshade and shell respectively by injection molding, then by welding, in order to remove
Internal stress in injection molding and welding process, it will usually arrange stress relief annealing, and can go out on lampshade and shell after annealing
Existing large batch of bulging, protuberance, are known as bulge phenomenon by this phenomenon.
In current lamps and lanterns development process, bulge situation there are two types of method assess, one is the Design of Luminaires stage with
Experience is assessed, this method precision, accuracy can not control, and the requirement to designer's experience is also very high；The
Two kinds are to arrange trial production to look at the bulge situation of lamps and lanterns after Design of Luminaires, and the structure of lamps and lanterns and mold etc. at this time
It all determines substantially, can return to be rectified and improved if at this moment there is bulge phenomenon, can not only cause a large amount of people in this way
The loss of power, material resources, and project process can be influenced.
Invention content
The present invention provides a kind of Reflex Reflector bulges that Reflex Reflector bulge situation can be predicted in the design phase
The appraisal procedure of value reduces the waste of man power and material.
In order to achieve the object of the present invention, used technical solution is：A kind of assessment side of Reflex Reflector bulge value
Method, Reflex Reflector include lampshade and shell, are included the following steps：
1) size for measuring Reflex Reflector is emulated according to the length value of the Reflex Reflector of measurement and width value in CAE

3) when the bulge of CAE simulation softwares simulation Reflex Reflector, the length of the simulation model by changing Reflex Reflector
Angle value and width value obtain the bulge value of corresponding Reflex Reflector；
4) relational model of the size and corresponding bulge value of Reflex Reflector is established according to the data of step 3)；
5) length value and width value for the Reflex Reflector for measuring step 1), the Reflex Reflector obtained using step 4)
Size the size of the bulge value of Reflex Reflector is assessed with the relational model of corresponding bulge value.
As the prioritization scheme of the present invention, the calculation formula of the bulge value Z of Reflex Reflector is in step 3)：
Z=t1-t0Formula 1
Wherein：t1For the spacing of bulge rear lampshade and shell, t0For the lampshade of non-bulge and the spacing of shell.
As the prioritization scheme of the present invention, the size of Reflex Reflector is with the relational model of corresponding bulge value：
Wherein, Z is the bulge value of Reflex Reflector, and x is the length value of Reflex Reflector, and y is the width of Reflex Reflector
Value, a, b and c are respectively constant coefficient, a=5.7379789, b=-19.597289, c=-637.54559.
As the prioritization scheme of the present invention, the value range of the length value of the simulation model of Reflex Reflector is 50mm-
The value range of 200mm, the width value of the simulation model of Reflex Reflector are 15mm-75mm.
The present invention has the effect of positive：The present invention can be after the design phase determines the size of Reflex Reflector, energy
Corresponding bulge situation is evaluated, to carry out measures to rectify and reform in advance, the waste of man power and material is greatly reduced, shortens
The development cycle of lamps and lanterns, exploitation and production to lamps and lanterns have important directive significance.
Description of the drawings
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is the simulation model schematic diagram of Reflex Reflector；
Fig. 2 is the sectional view of Reflex Reflector；
Fig. 3 is the relational graph of the size and corresponding bulge value of Reflex Reflector.
Wherein：101, lampshade, 102, shell.
Specific implementation mode
As shown in Figs. 1-3, the invention discloses a kind of appraisal procedure of Reflex Reflector bulge value, Reflex Reflector includes
Lampshade 101 and shell 102, include the following steps：
1) size for measuring Reflex Reflector is emulated according to the length value of the Reflex Reflector of measurement and width value in CAE
The simulation model of Reflex Reflector is established in software；
2) according to actual heat treatment annealing operating mode, the simulation method of the bulge of simulation Reflex Reflector, simulation are formulated
The simulation method of the bulge of Reflex Reflector is realized by CAE simulation softwares；
3) when the bulge of CAE simulation softwares simulation Reflex Reflector, the length of the simulation model by changing Reflex Reflector
Angle value and width value obtain the bulge value of corresponding Reflex Reflector；
4) relational model of the size and corresponding bulge value of Reflex Reflector is established according to the data of step 3)；
