Existing automobile inner cavity body insulation is the paster structure of two dimension, and it mainly is made of macromolecule foaming sound-absorbing sheet material, binder and silicone oil paper.The sound-absorbing effect of this kind material is general, and it has following drawback in the vehicle body production process:
1, there is error in the installation site: because this material is bonded on the inwall of bodywork cavity by binder, do not have fixing attachment point, the have positional error of then different workmans in work progress produces;
2, transport especially vehicle body in Coating Pretreatment and electrophoresis process at vehicle body after installing, owing to be that on-mechanical is installed, cause paster to break away from the vehicle body inwall easily, drop in the bypass cavity, in the high-speed motion of automobile, can cause bigger bypass noise so on the contrary;
3, after the vehicle length time used, owing to be subjected to factor affecting such as illumination ageing, binder was aging easily, and paster can break away from;
4, because the vehicle body inwall is covered by binder, and then vehicle body is in electrophoresis process, and the inwall panel beating can't be coated with electrophoretic paint, cause the corrosion of cavity inner wall easily, shorten automotive service life.
The utility model content
Problem to be solved in the utility model provides a kind of automobile cavity internal sound insulation blob of viscose, its objective is to intercept the cavity airflow field, reduces noise, promotes car load NVH performance.
To achieve these goals, the technical scheme taked of the utility model is:
This automobile cavity internal sound insulation blob of viscose provided by the utility model, comprise rack body, described rack body is captiveed joint with the vehicle body panel beating by buckle, and the distance of the bearing surface of described buckle and panel beating cross hatch is δ, the inserting surface angle is α, and keeping the face angle is β.

The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and principle of work, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
In order to solve the problem that exists at the described present known technology of this specification sheets background technology part and to overcome its defective, realize reducing noise, promote car load NVH performance.The technical scheme that the utility model is taked is:
As shown in Figure 1 to Figure 3, this automobile cavity internal sound insulation blob of viscose provided by the utility model, comprise rack body 2, described rack body 2 is captiveed joint with vehicle body panel beating 1 by buckle 3, the distance of the bearing surface of described buckle 3 and panel beating 1 cross hatch is δ, the inserting surface angle is α, and keeping the face angle is β.
The scope of described inserting surface angle [alpha] is 25～35 °.
Adopt technique scheme, described inserting surface angle [alpha] can influence assembly force, angle is steep more, and needed assembly force is big more between buckle 3 and the panel beating 1, and the inserting surface angle [alpha] can become big gradually in the process of inserting stamping holes on the other hand, therefore the inserting surface angle should be as much as possible little, to reduce assembly force, generally needed in process of production assembly force is controlled at about 50N, and angle with rational is between 25～35 °, can make the assembling difficulty more than or equal to 45 ° angles, should avoid as far as possible.
The scope of described maintenance face angle beta is 80～90 °.
Adopt technique scheme, keep the influence of face angle beta to keep and separating behavior, angle is steep more, keeps intensity and separating force just big more.For not needing to disassemble again after the 3D PIFI installation, be non-demolition part, separating force is had relatively high expectations, so the β design between 80～90 °, keeps the face angle should be approximately equal to 90 °, but also there is no need to be accurate to 90 °.The above angle of limit is called limiting angle, because the effect of friction, the effect of limiting angle is the same with 90 ° effect.Desired separating force should be greater than 150N in design, and this is a destructive force, and buckle will be destroyed, and generally can not use again.
