Description
Technical field
The present invention relates to a kind of vehicle rear cover containment member and sealing band hookup wire method of designing thereof, be specifically related to cooperating of a kind of vehicle rear cover sealing band and sealing band hookup wire and bonnet sealing surface, and matching relationship how to control these three systems.
Background technology
Nowadays automobile is as an indispensable part of people's daily life, liked by increasing people and as daily instrument of riding instead of walk, even enjoy as a kind of culture that the comfort level of automobile also more and more receives publicity like this.
As the bonnet sealing band system of one of most important element that satisfies the vehicle complete vehicle traveling comfort, the quality of its sealing effectiveness directly has influence on the waterproof and dustproof of car load, sound insulation, and then have influence on the comfort level of full car.Determine the quality of sealing system sealing effectiveness so, a very big factor is exactly sealing band and the matching relationship that correlated partss such as part, pressing part are installed, how to simulate the matching relationship between them more really and accurately, making it to reach the fiting effect of the best, is the target that a lot of projectors earnestly struggle.
According to general automobile design order, be after having designed automobile back wall aperture lines, begin to design the attachment face of bonnet sealing band, this attachment face also is the part of car load back wall.Conventional way is, is starting point with the back wall aperture lines, is reference with the bonnet rotation axis, and the path of motion of simulation bonnet is by rotating the installation limit of confirming sealing band.Conventional this way can not very accurate simulation bonnet and the matching relationship of sealing band, and angle tends to deviation to some extent, especially in the near more place of distance bonnet rotation axis, and the sealing attachment face that the method is made and actually differ just bigger.Especially near more apart from bonnet axis place also is the place (as Fig. 3, theoretical and actual 11.6 degree that differ) of error maximum, also be the hydraulic pressure maximum simultaneously herein, the place of the risk of leaking maximum, conventional design tends to cause poor sealing herein, leaks and leaks out.
In sum, have following technical matters in the prior art: the deviation that bonnet cooperates with sealing band has caused the poor sealing problems such as leaking, leak out of bonnet sealing band.
Summary of the invention
The object of the present invention is to provide a kind of sealing band hookup wire method of designing, it is specifically related to the matching relationship of vehicle rear cover sealing band and its related components, make the sealing surface of bonnet become the matching relationships of vertical 90 degree with the line of centers of sealing band, make sealing band obtain the sufficient compression of vertical direction.
Another object of the present invention is to provide a kind of vehicle rear cover containment member, the matching relationship between its member can make bonnet sealing band excellent sealing, the poor sealing defective such as leak out of avoiding leaking.
The present invention is by once conversion, aperture lines with back wall is a foundation, the bench mark of the attachment face of bonnet sealing band has been transferred to the contact position of sealing band and bonnet, with this contact point is benchmark, must open closing movement in conjunction with bonnet, simulated the matching relationship between sealing band and bonnet and the car load back wall exactly, thereby guaranteed sealing effectiveness, actv. prevents the generation of situations such as leaking more.
Concrete technical scheme is as follows:
A kind of vehicle rear cover sealing band hookup wire method of designing: at first determining the contact point of sealing band and vehicle rear cover, is that the bench mark of sealing band hookup wire is determined the sealing band hookup wire with this contact point.
Connect the point on this bench mark and the body rear wall aperture lines, its extended line is the hookup wire of sealing band.
With the point on the body rear wall aperture lines is that circle is done in the center of circle, crosses the tangent line that the hinge axes point is done this circle, and this points of tangency is a bench mark.
The concrete following steps that adopt:
(1) determines point on the automobile back wall aperture lines;
(2) determine the hinge axes point;
(3) be that a circle is done with a predetermined radii in the center with the point on the back wall aperture lines;
(4) cross the hinge axes point and do round tangent line;
(5) determine that tangent point is bench mark;
(6) point on connection bench mark and the back wall aperture lines, its extended line is exactly the hookup wire of sealing band.
Wherein said predetermined radii is at the beginning of design, the supplier of sealing band input.
The hookup wire of many described sealing bands constitutes final whole erection face.
A kind of vehicle rear cover containment member comprises sealing band, and sealing band hookup wire and bonnet sealing surface are the vertical relations of 90 degree between the line of centers of bonnet sealing surface and sealing band, and sealing band is installed on the sealing band hookup wire.
It between the line of centers of bonnet sealing surface and sealing band the approximately perpendicular relation about 90 degree.
The sealing band hookup wire is that bench mark is determined with the contact point of sealing band and vehicle rear cover.
With the point on the body rear wall aperture lines is that circle is done in the center of circle, crosses the tangent line that the hinge axes point is done this circle, and this points of tangency is described bench mark.
Compare with present prior art, the present invention has found the real bench mark of bonnet sealing band exactly, thereby accurately makes the attachment face of sealing band, and the bonnet sealing band is accurately cooperated with attachment face, sealing surface, makes theoretical design guarantee consistent with actual conditions.

The specific embodiment
Describe the present invention with reference to the accompanying drawings below, it is a kind of preferred embodiment in the numerous embodiments of the present invention.
For clearly embodying the difference with prior art, at first simply introduce technical scheme of the prior art: before design sealing attachment face in conjunction with Fig. 2, what can decide is hinge axes point 4 and the point 6 above the back wall aperture lines, conventional way is to be benchmark to put 6, do the straight line of vertical point 4 and point 6 lines, promptly obtain the attachment face/line of sealing band,, can obtain final attachment face by there not being several such lines.Thing followed problem is that the real bench mark of sealing band attachment face should be a sealing band and sealing surface point of compression 5 mutually, rather than the point 6 among the figure.Method of the prior art is to have replaced a little 5 with point 6 is approximate, and this has just produced the deviation of spending as 11.6 among Fig. 3.
By method of the present invention, can find real bench mark 5 exactly, as Fig. 4, hinges known axis point 4, the point 6 above the back wall aperture lines, be that center do a circle 7 to put 6 this moment, radius of a circle is at the beginning of design, the supplier of sealing band input, cross the tangent line that point 4 is done circle 7, tangent point be exactly our bench mark 5 that will find ', point of connection 5 ' and put 6, its extended line is exactly the hookup wire of sealing band, by countless such lines, just can make the attachment face of sealing band.
As Fig. 5, the rotational trajectory of the mounting center wired-AND gate of sealing band is just in time tangent, and the correctness of sealing bar attachment face has been described.As Fig. 6, be the comparison in new and old cross section, thick line is the matching relationship of the inventive method, fine rule is the cross section of prior art matching relationship, by relatively, can draw the improvement and the advantage of technical solution of the present invention.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present invention and technical scheme to carry out; or directly apply to other occasion without improvement, all within protection scope of the present invention.
