In the effective point of fixity distribution design method of car belt of the present invention, in order to ensure that each parts of formed automobile can mate mutually, co-ordination, and avoid need to carrying out owing to adopting different coordinates inconvenience and the issuable mistake that later stage coordinate conversion processing causes, first need on automobile, set a reference point, then set up benchmark three rectangular coordinate systems taking this reference point as initial point.Example as shown in Figure 1, these type of benchmark three rectangular coordinate systems (being designated hereinafter simply as " coordinate system ") are chosen for reference point by the O point on automobile in the figure exactly, and then using vehicle body longitudinally as X-axis and taking tailstock direction as X-axis forward, vehicle body is laterally as Y-axis, and bodywork height direction is as Z axis.So, in the time carrying out the design of the effective point of fixity of securing band, just can be according to above-mentioned coordinate system as the design coordinate system in whole design process, thus needn't carry out again the later stage coordinate conversion work that any complexity is loaded down with trivial details.
In the time using the inventive method, also need more default design parameters, such as seat angle of body α, seat reference point for the design R, seat mean breadth and the vehicle body mean breadth etc. in above-mentioned coordinate system.Basic meaning and the facilities thereof of these parameters will be illustrated below.
While carrying out the object of the effective point of fixity distribution design of securing band, in order effectively to protect occupant safety, also should take into account the comfortableness of wearing simultaneously.So the design of the effective point of fixity of securing band is to sit the position occupied on the seat and sitting posture thereof as basic taking occupant, as shown in Figure 2, this position of being occupied is called seat reference point R, for example, and sitting posture normally represents (conventionally with the angle of Z axis within the scope of 20 °-30 °, be preferably made as 25 ° under situation) with seat angle of body α.In addition, in the methods of the invention, seat mean breadth, these two dimensional parameters of vehicle body mean breadth are all as important reference data, so that be all to adopt unified ratio reference object in the time carrying out complicated design processing, thereby contribute to realize Parametric designing.
In some preferred situations, also need to arrange more design parameter.For example, because the movement of seat will have influence on protectiveness and the comfortableness of securing band to occupant, in the time carrying out the effective point of fixity distribution design of car belt, preferably just consider in advance the extreme position that seat moves for this reason.Refer to again Fig. 2, carrying out before the effective point of fixity distribution design of securing band except setting the above-mentioned parameter such as seat reference point R coordinate, seat angle of body α, also need default 4 seat moving limit position reference point for the designs, they comprise that respectively front high position reference point for the design R1, front lower position reference point for the design R2, rear lower position reference point for the design R3 and rear high-lying put reference point for the design R4.As shown in Figure 2, in fact the reference point for the design R of seat is comprised in the region being limited by above-mentioned 4 seat moving limit position point R1-R4.And for example, in the time designing, may also need to limit effectively point of fixity upper and lower limit coordinate points location parameter value in some coordinate axis (as Z axis) in coordinate system such as snap close, dististyle.
About concrete numerical value how reasonably to preset above-described various extreme positions in coordinate system, this be with the various relevant design specifications of the effective point of fixity of securing band (for example, international standard, national standard, industry standard, company standard, design manual or other specifications etc.), engineering staff or designer's the aspect such as experience and design requirement is relevant, because this part content can be understood or know by those skilled in the art, describe so do not do in this article emphasis.
Completed above-mentioned coordinate system and respective design parameter work is set after, just can determine subsequently the coordinate position of the effective point of fixity S of snap close in this coordinate system.An embodiment who adopts the inventive method has been shown in Fig. 3 and Fig. 4, this embodiment is based on effective snap close point of fixity S being arranged on the seat or this two kinds of possible situations on vehicle body, in conjunction with Fig. 3 and Fig. 4, design procedure process being wherein described in detail respectively below.
For the setting position of snap close, the aspect such as design feature and intensity load-bearing capacity that first needs to consider seat, vehicle body is arranged on the seat or on vehicle body because usually determining.Can be by snap close setting on the seat if judged, this will be conducive to carry out snap close operation, the effective point of fixity S of snap close can be along with seat moves and produces and relatively move, and therefore just do not need the position distribution scope that limits planes and determine the effective point of fixity S of snap close with two yet.Please specifically with reference to figure 3, first preset T1 in coordinate system, X, the Z axis coordinate of this T1 are identical with X, the Z axis coordinate of reference point for the design R, but its Y-axis coordinate with the be separated by distance of 0.5 times of seat mean breadth of the Y-axis coordinate of reference point for the design R;
Then, again as shown in Figure 3, P1 plane is set in coordinate system, this P1 plane is to intersect by reference point for the design R and with forming sharp angle α 1 (it is preferably set within the scope of 50 °-70 °) between XY plane, this P1 plane and the XY plane intersecting lens and Y-axis keeping parallelism between the two simultaneously.Next, make to be parallel to the E plane of XZ plane by a T1, this E plane and P1 Plane intersects obtain intersecting lens L1; By some S, the default upper and lower limit coordinate points on Z axis (can be determined above-mentioned upper and lower limit coordinate points according to specific design situation again, for example upper limit coordinate points can be arranged to than the Z axis coordinate figure of reference point for the design R little 0.2 times～0.3 times of seat mean breadth) make to be parallel to respectively the plane of XY plane, to make them obtain intersecting lens L2 and L3 with P1 Plane intersects respectively, so just obtain by the intersecting lens L1 first intersection point p12 that form crossing with L2, intersected by intersecting lens L1 and L3 the second intersection point p13 forming.Thus, by under snap close setting situation on the seat, just obtained the reasonable Arrangement scope of the effective point of fixity S of snap close by above step, be arranged on the line segment between the first intersection point p12 and the second intersection point p13 by it, the effective point of fixity arrangement of this snap close can constrain in occupant's buttocks on automotive seat effectively.
Please refer to again Fig. 4, if after considering the aspect such as design feature and intensity load-bearing capacity of seat, vehicle body, judge and be not suitable for snap close setting to change and be located on vehicle body on the seat, set-point T2 make itself and above-mentioned some T1 be positioned at phase the same side of the Y-axis coordinate points of reference point for the design R, X, the Z axis coordinate of point T2 is also configured to identical with X, the Z axis coordinate of reference point for the design R, and the Y-axis coordinate of a T2 is arranged to and the be separated by distance of 0.6 times of seat mean breadth of the Y-axis coordinate of reference point for the design R;
Next, P2 plane and P3 plane are set respectively in the coordinate system shown in Fig. 4.Wherein, P2 plane is configured to acutangulate α 2 (it is preferably set within the scope of 35 °-55 °) by reference point for the design R and with XY planar shaped, and the intersecting lens between this P2 plane and XY plane is parallel to Y-axis simultaneously; And P3 plane is to be configured to by reference point for the design R, and acutangulate α 3 (it is greater than sharp angle α 2, and is preferably set within the scope of 70 °-90 °) with XY planar shaped, the intersecting lens between this P3 plane and XY plane is parallel to Y-axis simultaneously.Then, make to be parallel to the F plane of XZ plane by a T2, this F plane obtains intersecting lens L4 and L5 with P2 plane and P3 Plane intersects respectively.Subsequently, by some S, the default upper and lower limit coordinate points on Z axis (can be determined above-mentioned upper and lower limit coordinate points according to specific design situation again, for example upper limit coordinate points can be arranged to than the Z axis coordinate figure of reference point for the design R little 0.2 times～0.3 times of seat mean breadth) make to be parallel to respectively the plane of XY plane, to make them obtain intersecting lens L6 and L7 with F Plane intersects respectively.Like this, snap close is being arranged under the situation on vehicle body, just obtain the reasonable Arrangement scope of the effective point of fixity S of snap close, be arranged on by above-mentioned intersecting lens L4, L5, L6 and L7 and intersect each other in formed closed region by it, adopt the effective point of fixity arrangement of snap close shown in the present embodiment occupant's buttocks can be constrained on automotive seat effectively.
After having obtained the distributing position of the effective point of fixity S of snap close by the above example of the inventive method, under preferred situation, can also further implement checking procedure and proofread the coordinate position of this effective point of fixity and whether meet design specifications, if do not met, re-execute above corresponding steps until meet design specifications.About above-mentioned design specifications, it can international standard, national standard, industry standard, company standard, design manual, designing requirement or otherwise specification etc., because this part content belongs to prior art and is understood or know by those skilled in the art, so seldom repeat at this.
Be further described another embodiment of the inventive method below in conjunction with Fig. 5, Fig. 6, so that can understand better design process of the present invention, feature and advantage thereof.
That situation is set is similar with aforesaid snap close, the position of dististyle is also to consider according to aspect factors such as the design feature of seat, vehicle body and intensity load-bearing capacitys, determine to be arranged on the seat or on vehicle body, and according to these two kinds of different situations adopt respectively following step carry out respective design processing with the effective point of fixity D of acquisition dististyle the coordinate position in coordinate system.
As shown in Figure 5, can be by dististyle setting on the seat if confirmed, preset T3 first, X, the Z axis coordinate of this T3 are identical with X, the Z axis coordinate of reference point for the design R, make invocation point T3 and aforesaid some T1 be symmetrical arranged about reference point for the design R, so just by a T3, the position in coordinate system has been carried out unique definite simultaneously;
Subsequently, in the coordinate system shown in Fig. 5, continue to arrange P4 plane, this P4 plane is that to acutangulate α 4 (it is preferably set within the scope of 50 °-70 °) crossing by reference point for the design R and with XY planar shaped, should make the intersecting lens between P4 plane and XY plane be parallel to Y-axis simultaneously.Then, make to be parallel to the G plane of XZ plane by a T3, to make this G plane and P4 Plane intersects obtain intersecting lens L8; By some D, the default upper and lower limit coordinate points on Z axis (can be determined above-mentioned upper and lower limit coordinate points according to specific design situation again, for example upper limit coordinate points can be arranged to than the Z axis coordinate figure of reference point for the design R little 0.3 times～0.5 times of seat mean breadth) make to be parallel to respectively the plane of XY plane, to make them obtain intersecting lens L9 and L10 with P4 Plane intersects respectively, so just obtain by the intersecting lens L8 three intersection point p89 that form crossing with L9, intersected by intersecting lens L8 and L10 the 4th intersection point p810 forming.By above step, just its rational layout scope will obtained under dististyle setting situation on the seat, be arranged on the line segment between the 3rd intersection point p89, the 4th intersection point p810 by the effective point of fixity D of dististyle, the effective point of fixity arrangement of this dististyle can ensure the effect on automotive seat by occupant's buttocks operative constraint.
When considering behind the aspect such as design feature and intensity load-bearing capacity of seat, vehicle body, determine suitable dististyle is arranged on vehicle body instead of on the seat time, this mode is conducive to reduce the design strength of seat, and in the time that seat moves, the effective point of fixity of dististyle will move and need to determine the layout scope of the effective point of fixity of dististyle by two restriction planes relative to seat.
While design in the situation that dististyle is arranged on vehicle body, as shown in Figure 6, first set-point T4, make the X of a T4, the X of Z axis coordinate and reference point for the design R, Z axis coordinate is identical, and guarantee point T4 and Y-axis coordinate points separately of some T3 are all phase the same side of being positioned at the Y-axis coordinate points of reference point for the design R (put T4 and aforesaid some T2 and be minute not homonymy) in reference point for the design R in Y direction, the Y-axis coordinate of a T4 is arranged to and the be separated by distance of a setting of the Y-axis coordinate of reference point for the design R simultaneously, this distance equals the difference between the Y-axis coordinate absolute value of 0.5 times of vehicle body mean breadth and reference point for the design R,
