Abstract
The invention discloses a sound insulation gasket for a car body cavity. First expansion rubbers (2) with the same thickness are adhered onto the peripheral lateral wall of a supporting framework (1), second expansion rubbers (3) with the same thickness are adhered onto the front plane and the rear plane of the supporting framework (1), a through hole (1a) penetrating through the front plane and the rear plane is formed in the supporting framework (1), and a third expansion rubber (4) is filled in the through hole (1a). The peripheries of the second expansion rubbers (3) are connected with the first expansion rubbers (2), the third expansion rubber (4) enables the second expansion rubbers (3) on the front plane and the rear plane to be connected, and accordingly, the first expansion rubbers (2), the second expansion rubbers (3) and the third expansion rubber (4) are connected into a whole. Due to the fact that the expansion rubbers are adhered onto all the outer surface of the whole supporting framework, the contact area between the supporting framework and the expansion rubbers is enlarged, falling or poor forming during electrophoresis is avoided, and block effect on air flow in the car body cavity can be better.
Description
Technical field
The present invention relates to vehicular spare parts, specifically, is a kind of sound insulating seal pad for filling car internal cavity, during to block and to block galloping, and the swiftly flowing object of air in bodywork cavity.
Background technology
Sound insulation gasket for car body cavity is for being arranged between metal sheet or in cavity that metal sheet and support beam are formed, for under blocking-up and retardance galloping state, the swiftly flowing object of empty chamber air, thus the noise that reduction air-flow produces, play the effect of sound insulating seal.The shape of sound insulating seal pad is roughly the same with the shape of vehicle body internal cavity.
As shown in Figure 1 and Figure 2, sound insulation gasket for car body cavity comprises support frame 1 and expansion glue 5 two parts.Support frame 1 comprises frontal plane, back plane and circumferential side wall, and support frame 1 is provided with buckle 1b.The circumferential side wall of support frame 1 is stained with the equal expansion glue of a layer thickness 5.In actual production process, find that coming off or shaping bad situation often appears in the expansion glue in support frame 1 circumferential side wall, trace it to its cause, mainly vehicle body is through electrophoresis operation, electrophoresis liquid is washed away at interior of body and is formed certain impulsive force, and expansion glue 5 is too little with the area of contact of support frame 1 profile, after causing electrophoresis operation to complete, expansion glue 5 comes off or shaping bad.
Summary of the invention
The present invention aims to provide the strong sound insulation gasket for car body cavity of a kind of shock-resistant ability, can ensure that expansion glue sticks on support frame tightly, prevents from occurring during electrophoresis operation coming off or shaping bad situation.
For this reason, the technical solution adopted in the present invention is: a kind of sound insulation gasket for car body cavity, comprise support frame, described support frame comprises frontal plane, back plane and circumferential side wall, the circumferential side wall of described support frame is stained with the first expansion glue that thickness is equal, key is: the forward and backward plane of described support frame is stained with the second expansion glue that thickness is equal, described support frame has the intercommunicating pore of through forward and backward plane, is filled with the 3rd expansion glue in described intercommunicating pore; The periphery of the second expansion glue is connected with the first expansion glue, and the second expansion glue in forward and backward plane is connected by the 3rd expansion glue, thus first, second, third expansion glue is connected as a single entity.
Be preferably, the thickness of described first expansion glue is greater than the thickness of the second expansion glue.Owing to being also filled with expansion glue in the intercommunicating pore of support frame, the second expansion glue in forward and backward plane is connected as a single entity by the 3rd expansion glue, therefore, only needs to adhere to the thin expansion glue of one deck in the forward and backward plane of support frame, just can ensure adhesiving effect.
For convenience of the installation of sound insulating seal pad, described support frame is provided with the buckle be connected with vehicle body.
Beneficial effect of the present invention: by setting up the second expansion glue in the forward and backward plane of support frame, and set up the 3rd expansion glue of the forward and backward plane of through support frame, and be connected as a single entity with existing second expansion glue, thus ensure that the outside face of support frame is all stained with expansion glue, the area of contact of support frame and expansion glue is obviously increased, guarantee that expansion glue can stick on support frame tightly, prevent from occurring in electrophoresis operation coming off or shaping bad situation; In addition, from the acoustic efficiency of whole sound insulating seal pad because former support frame inside be also distributed with expansion glue now, in bodywork cavity air flow blocking-up and blockage effect better.

Fig. 2 is the birds-eye view of Fig. 1.
Fig. 3 is the structural representation after improving.
Fig. 4 is the birds-eye view of Fig. 3.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
Shown in composition graphs 3 and 4, a kind of sound insulation gasket for car body cavity, is made up of support frame 1, expansion glue.Support frame 1 comprises frontal plane, back plane and circumferential side wall.The circumferential side wall of support frame 1 is stained with the first expansion glue 2 that thickness is equal, and support frame 1 is generally resistant to elevated temperatures nylon material.The above is consistent with existing sound insulation gasket for car body cavity structure.
Difference is: the forward and backward plane of support frame 1 is stained with the second expansion glue 3 that thickness is equal, support frame 1 has the intercommunicating pore 1a of through forward and backward plane, be filled with the 3rd expansion glue 4 in intercommunicating pore 1a; The periphery of the second expansion glue 3 is connected with the first expansion glue 2, the second expansion glue 3 in forward and backward plane is connected by the 3rd expansion glue 4, thus first, second, third expansion glue 2,3,4 is connected as a single entity, thus the outside face of whole support frame 1 is made to be inflated glue parcel.
Preferably, the thickness of the first expansion glue 2 is greater than the thickness of the second expansion glue 3.
For convenience of the installation of sound insulating seal pad, support frame 1 is provided with the buckle 1b be connected with vehicle body, other interface arrangments also can be adopted to be connected with vehicle body.
Claims (3)
1. a sound insulation gasket for car body cavity, comprise support frame (1), described support frame (1) comprises frontal plane, back plane and circumferential side wall, the circumferential side wall of described support frame (1) is stained with the first expansion glue (2) that thickness is equal, it is characterized in that: the forward and backward plane of described support frame (1) is stained with the second expansion glue (3) that thickness is equal, described support frame (1) has the intercommunicating pore (1a) of through forward and backward plane, in described intercommunicating pore (1a), be filled with the 3rd expansion glue (4); The periphery of the second expansion glue (3) is connected with the first expansion glue (2), and the second expansion glue (3) in forward and backward plane is connected by the 3rd expansion glue (4), thus first, second, third expansion glue (2,3,4) is connected as a single entity.
