Embodiment Construction

[0015] see figure 1 , with reference to figure 2 , image 3 , the upper inner side of the A-pillar of a car according to the present invention is used for presetting in the inner cavity of the upper inner side of the A-pillar of a car during the manufacturing process of the car body. The sound insulation block is in the shape of a polyhedron as a whole, and includes a skeleton 1 and a foam body 2 . The entire sound-insulating block has a plane shape similar to the section of the vehicle body cavity in the upper inner side of the A-pillar of the car, and leaves a gap with the periphery of the corresponding section for foaming and expansion of the foam body.

[0016] An opening 11 is provided on one side of the plate-shaped frame 1, a hole 12 is provided in the middle of the plate-shaped frame 1 and communicated with the above-mentioned opening, and a groove for embedding foam is provided on the periphery of the plate-shaped frame 1 , two adjacent sides of the plate frame 1 ...

Abstract

A sound insulation block on the inner side of the upper part of the A-pillar of a car, including a heat-resistant plate-shaped frame and a foaming body that can expand after being heated after being connected to the frame. A hole is provided in the middle and communicates with the above-mentioned opening, and at least one fixing piece connected and fixed to the corresponding parts inside the upper part of the A-pillar is provided on the periphery of the plate-shaped frame; the foam body is embedded around the plate-shaped frame , fill the opening and insert it inside the channel to form an inner hole for the circulation of pickling, neutralization, phosphating and purification liquids. The sound insulation block of the present invention is preset in the inner side of the upper part of the A-pillar of the car, and after being foamed and expanded, it can be tightly bonded to the body panel at the place, effectively blocking and blocking the cavity passage at the place, and further improving And improve the purpose of vibration isolation, sound insulation, vibration reduction and noise reduction in the car cockpit. The inner sound insulation block at the upper part of the A-pillar of the car of the present invention is applied to the M2 model of China Junjie.

Description

technical field [0001] The invention relates to an automobile part, in particular to a sound insulation block on the inner side of the upper part of an A-pillar of a car and an application thereof. Background technique [0002] With the development of the automobile industry, people have higher and higher requirements for the "safety, comfort, and environmental protection" of cars, and the standard requirements for "sound insulation, vibration isolation, anti-corrosion, and noise prevention" in the cockpit of cars are also constantly improving. . At present, automotive engineers and technicians have upgraded the technology of sound insulation and vibration isolation for vehicle shock absorbers, sound insulation and heat insulation pads, interior sound insulation, vibration isolation carpets, body glass, and car roofs in the car, making the interior of the car cockpit The vibration and noise have been effectively improved. However, the cavity channel in the body structure a...
