Description

Anti-drop automobile body panel beating cavity sound insulating block

Technical Field

The utility model belongs to the technical field of the sound insulation piece, a anti-drop automobile body panel beating cavity sound insulation piece is related to.

Background

With the development of the automobile industry, the requirements of people on the safety, comfort and environmental protection of cars are higher and higher, and the standard requirements on sound insulation, vibration isolation, corrosion prevention and noise prevention in a car cabin are also continuously improved. At present, automobile engineering technicians in a car have upgraded the sound insulation and vibration isolation technologies of a vehicle shock absorber, a sound insulation and heat insulation pad, car interior sound insulation, a vibration isolation carpet, car body adhesive glass, a car roof and the like, so that the vibration and noise in the car cabin are effectively improved. However, the cavity channels in the body structure also generate and transmit vibration noise, which is not always well solved.

The automobile body is manufactured by punching a metal plate by a die and then welding automobile plates such as an inner plate, a reinforcing plate, an outer plate and the like. Therefore, necessary gaps and spaces are formed between the inner panel, the reinforcement panel and the outer panel, and cavities are formed in the areas including the floor beam of the vehicle body, the A, B, C, D pillar, the rear wheel cover, the ceiling, the front panel at the upper and lower ends, the ceiling, the upper end of the rear fender panel, and the four door panels. In particular, the pillar and bottom side rails of the body reinforcement A, B, C, D form hollow, cylindrical structural members. The hollow structure of these pillars and side members effectively secures the strength and rigidity of the vehicle body structure, and therefore the state of the cavity in the vehicle body structure is essential. The cavity of such a body structure also forms a special channel for transmitting external noise and vibration. When the roof, the longitudinal beams and other metal plates of the vehicle body are in the same shape, the sound is generated due to the distortion and the vibration of the structure when the aisle access sill is in the aisle access sill; resonance sound is generated to the vehicle body due to external wind pressure and wind resistance during high-speed running of the vehicle; the road surface sand and stone can also cause impact sound to the vehicle body in motion; the resonance frequency generated during the motion causes vibration and sound to the vehicle body panel. The noise and vibration can be quickly transmitted in the cavity between the inner plate and the outer plate of the car body, so that the noise and vibration are transmitted into a cabin of the car, and the comfort of drivers and passengers is affected.

Chinese patent ZL201120189735.5 discloses a cavity sound insulation block arranged on the inner side of the upper part of a pillar of a car, which comprises a high temperature resistant support framework and an expansion body material embedded on the framework and capable of foaming and expanding after being heated, wherein the planar shape of the support framework is similar to the cross-sectional shape of the cavity on the inner side of the upper part of the pillar of the car, an umbrella-shaped buckle for being clamped into a metal plate on the inner wall of the cavity is arranged on the middle back of the support framework, and side-turning prevention structures are respectively arranged in front of and behind the umbrella-shaped buckle, and are plate structural members formed by the framework material and the expansion body material which are connected into a whole. Although the problem that the framework turns on one's side has been solved to a certain extent to this patent, connect the elasticity buckle between support framework and the automobile body in follow-up use, lead to the puigging piece to drop scheduling problem because the automobile body frequently vibrates very easily.
