Description
Technical field
The present invention relates to automobile technical field, particularly relate to a kind of vehicle seat design method.
Background technology
H point is tie point and hip point (HipPoint) of human body trunk and thigh in two dimension or three-dimensional (3 D) manikin model, it human body template is hip joint, in entire vehicle design performance history, the exactness determining H point position is extremely important, it is the reference point of entire vehicle design, not only the oval position in vehicle body of eye is determined in impact, also directly has influence on all many-sides such as determination of the layout of the location of officer's Manual Acupuncture, various lever piece member and instrument, the layout of steering wheel position, the clearance space of head and top cover height. Motor vehicle society of engineers of the U.S. (SocietyofAutomotiveEngineers, SAE) according to the difference of officer actual H point position in vehicle body system of coordinates when respective agreeable vehicle driving posture of different stature, the officer for difference hundredths has counted one group of H point curve:
X975=936.6+0.613879H30-0.00186247(H30)2
X95=913.7+0.672316H30-0.00195530(H30)2
X90=885.0+0.735374H30-0.00201650(H30)2
X50=793.7+0.903387H30-0.00225518(H30)2
X10=715.9+0.968793H30-0.00228674(H30)2
X5=692.6+0.981427H30-0.00226230(H30)2
X25=687.1+0.895336H30-0.00210494(H30)2
Wherein, Xi is the horizontal throw that the H point of the officer of the i-th hundredths stature is positioned at the rear of thumb reference point (BOF), and its unit is mm.
This curve characterizes the conventional position of different hundredths officer H point when agreeable vehicle driving posture, utilizes it can directly determine corresponding to the position of H point under different H point height (H30:H point is to the vertical range called in person and put) in vehicle body.
The layout of automotive seat and whole car vehicle body needs to carry out according to the H agreeable position line of point, the determination of traditional H agreeable position line of point needs in above-mentioned curve equation corresponding with the hundredths of officer for the input of multiple H30 value according to automobile type, agreeable position line result is determined accurately in order to obtain, input more many H30 values more good, but this adds the complicacy of calculating undoubtedly, and often calculate one group of numerical value then need to carry out once check and checking, process is loaded down with trivial details and accuracy is not high.

Accompanying drawing explanation
Fig. 1 is the vehicle seat design method schema according to one embodiment of the present invention.
Embodiment
Vehicle seat design method provided by the invention, by reference to the accompanying drawings and embodiment be described in detail as follows.
The method of the present invention is applicable to the design of A class automotive seat and the layout of whole car vehicle body. Regulation according to SAE, A class automobile (classAvehicles): refer to that seat reference point (SgRP) is (127��405) mm to the scope of the vertical range (H30-1) of heel point, the track angle of elevation A19 > 0 degree of H point, turning to dish diameter (W9) to be less than 400mm, backrest angle (A40-1) is (15��40) degree.
As shown in Figure 1, step is comprised according to the vehicle seat design method of one embodiment of the present invention:
S1. determine accelerator pedal heel point AHP and accelerator pedal reference point APP, the Y-direction coordinate of H point in whole car system of coordinates is set, sets up the plumbous vertical plane being parallel to XZ plane at the Y-direction coordinate place of H point.
S2., in this lead vertical plane, the preset length of this line segment can be arranged according to experience, is generally 127-405mm along the line segment of the extension of Z axle and the intersection point through this AHP and APP to set up one, is preferably 405mm in the present embodiment.
S3. according to officer's hundredths, according to following formula, this line segment is carried out matching, it is determined that the agreeable position line of H point:
Y=a+b*(X*d)-c(X*d)2
Wherein: a, b, c are corresponding to officer's hundredths three variable parameters, the value of corresponding one group of fixing a, b, the c of different officer's hundredths, d is the preset length of described line segment;
When officer's hundredths is 97.5, the value of a, b, c is respectively: 936.6,0.613879,0.00186247;
When officer's hundredths is 95, the value of a, b, c is respectively: 913.7,0.672316,0.00195530;
When officer's hundredths is 90, the value of a, b, c is respectively: 885.0,0.735374,0.00201650;
When officer's hundredths is 50, the value of a, b, c is respectively: 793.7,0.903387,0.00225518;
When officer's hundredths is 10, the value of a, b, c is respectively: 715.9,0.968793,0.00228674;
When officer's hundredths is 5, the value of a, b, c is respectively: 692.6,0.981427,0.00226230;
