Abstract
The utility model relates to a vehicle spare part field especially relates to a cavity and cuts off the mechanism. A vehicle cavity cuts off assembly, includes the skeleton partition panel, the outer lane of skeleton partition panel is connected with the insulating shutoff circle of round, one end fixedly connected with a slice welded connection piece of skeleton partition panel, and the axis of skeleton partition panel is 90 30 with the face of weld angle of welded connection piece. The utility model discloses vehicle cavity cuts off assembly's the welded fastening that passes through in the cavity, utilizes insulating shutoff circle and skeleton partition panel to cooperate and cuts off the cavity, improves white automobile body gas tightness, the noise reduction, in the great cavity of specially adapted cross -sectional width, make things convenient for the wall operation, reduced the wall cost.
Description
Technical field
The utility model relates to vehicle component field, particularly relates to a kind of cavity separating mechanism.
Background technology
Along with improving constantly of people's Environmental awareness, vehicle noise problem has caused the great attention of the whole society. Therefore, it is to increase the noise control level of vehicle has become new focus of the competition and technological development direction.
When high velocity air in vehicle side cavity and cavity obstacle rub, eddy current can be formed in cavity wall, produce turbulent air noise, cause the resonance of sheet metal component, thus produce cavity panel beating resonance noise, and pass-by noise is also served transmission effect by high velocity air. So cavity cuts off and become automobile cavity and fall one of gordian technique of making an uproar, cut off the resistance to air loss that can improve body in white by cavity, intercept the transmission in panel beating cavity such as noise, flue dust.
The implementation method that conventional cavity cuts off is connected in panel beating cavity for cutting off block at welding shop, foams in the electrophoresis drying room of application workshop, cavity filling. The volume production car later stage, cavity partition mode promoted NVH (Noise, Vibration, Harshness) performance by increasing. When cavity overall width is greater than 30mm, bonding way cannot being used in theory to connect, current technology can only use card to connect or spiral shell connects mode and connects; The precondition that card connects or spiral shell connects to open open holes on panel beating. Major part situation panel beating existing mold cannot be met by increase drift to add hole, needs additionally to increase a sequence mould, and this causes cost greatly to increase.
Prior art, a kind of automobile cavity damping foaming sheet of Chinese patent, CN201320757642.7, it is provided that be a kind of adhered partition block. A kind of automobile cavity sound insulating seal part of Chinese patent, CN201420537248.7, it is provided that be the partition block of a kind of bolt connection type. A kind of sound insulation rubber block in automobile cavity of Chinese patent, CN201020141359.8, it is provided that be the partition block that a kind of card connects formula. Above three patents all fail to solve that cavity is relatively big and the problem of panel beating perforate difficulty.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of vehicle cavity and cuts off total one-tenth, and this partition always becomes to be fixed by welding in cavity, utilizes insulation shutoff circle and skeleton partition panel to match and is cut off by cavity, it is to increase body in white resistance to air loss, reduces noise; It is specially adapted in the bigger cavity of cross-sectional width, facilitates partition operation, reduce partition cost.
The utility model is achieved in that a kind of vehicle cavity cuts off total one-tenth, comprise skeleton partition panel, the outer ring of described skeleton partition panel is connected with a circle insulation shutoff circle, one end of skeleton partition panel is fixedly connected with a slice and is welded to connect sheet, and the axis of skeleton partition panel and the face of weld angle being welded to connect sheet are 90 �� �� 30 ��.
The described sheet that is welded to connect is the angle bar being bent into certain angle, and the side being welded to connect sheet is fixed on skeleton partition panel as connecting arm embedding, and another side being welded to connect sheet is face of weld.
The described nook being welded to connect sheet is provided with an inner fovea part.
The zygomorphy of described insulation shutoff circle is provided with one to welding pilot hole.
The material of described insulation shutoff circle is EVA foam material.
Described skeleton partition panel is sheet metal component or nylon material.
What the utility model vehicle cavity partition always became is fixed by welding in cavity, utilizes insulation shutoff circle and skeleton partition panel to match and is cut off by cavity, it is to increase body in white resistance to air loss, reduction noise; It is specially adapted in the bigger cavity of cross-sectional width, facilitates partition operation, reduce partition cost.
