Abstract
The utility model discloses a sound insulation sealing pad used in a cavity of an automotive body. The circumferential side wall of a supporting framework (1) is adhered with first expansion glue (2) with the same thickness as the supporting framework, the front plane and the rear plane of the supporting framework (1) are adhered with second expansion glue (3) with the same thickness as the supporting framework, the supporting framework (1) is provided with an intercommunicating hole (1a) running through the front plane and the rear plane, the intercommunicating hole (1a) is filled with third expansion glue (4), the periphery of the second expansion glue (3) is connected with the first expansion glue (2), and the third expansion glue (4) is used for connecting the second expansion glue (3) on the front plane with the second expansion glue (3) on the rear plane, so that the first expansion glue (2), the second expansion glue (3) and the third expansion glue (4) are connected into a whole. The outer surfaces of the whole supporting framework are all adhered with the expansion glue, so that the contact area between the supporting framework and the expansion glue is increased, the condition of falling or poor forming in an electrophoresis working procedure is avoided, and the effects of blocking and retarding air flow in the cavity of the automotive body are better.
Description
Technical field
The utility model relates to vehicular spare parts, specifically, is a kind of for filling the sound insulating seal pad of car internal cavity, when blocking and blocking galloping, and the swiftly flowing object of air in bodywork cavity.
Background technology
Auto body cavity sound insulating seal pad is used for being arranged between metal sheet or the cavity of metal sheet and support beam formation, under blocking-up and retardance galloping state, the swiftly flowing object of air in cavity, thus the noise that air-flow produces reduced, play the effect of sound insulating seal.The shape of the shape of sound insulating seal pad and vehicle body internal cavity is roughly the same.
As shown in Figure 1 and Figure 2, auto body cavity sound insulating seal pad comprises support frame 2 and expansion glue 2 two parts.Support frame 1 comprises frontal plane, back plane and circumferential side wall, is provided with buckle 1b on support frame 1.In the circumferential side wall of support frame 1, be stained with the expansion glue 2 that a layer thickness is equal.In actual production process, find that situation about coming off or moulding is bad often appears in the expansion glue in support frame 1 circumferential side wall, trace it to its cause, while being mainly vehicle body process electrophoresis operation, electrophoresis liquid is washed away and is formed certain impulsive force at interior of body, and expansion glue 2 is too little with the area of contact of support frame 1 profile, cause electrophoresis operation to complete after expansion glue 2 come off or moulding bad.
Utility model content
The utility model aim to provide a kind of shock-resistant ability strong for the sound insulating seal pad in auto body cavity, can guarantee that expansion glue sticks on support frame tightly, while preventing electrophoresis operation, there is situation about coming off or moulding is bad.
For this reason, the technical scheme that the utility model adopts is: a kind of for the sound insulating seal pad in auto body cavity, comprise support frame (1), described support frame (1) comprises frontal plane, back plane and circumferential side wall, in the circumferential side wall of described support frame (1), be stained with the first expansion glue (2) that thickness equates, key is: before described support frame (1), on back plane, be stained with the second expansion glue (3) that thickness equates, described support frame has before perforation on (1), the intercommunicating pore of back plane (1a), 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 3rd expansion glue (4) is connected the second expansion glue (3) in forward and backward plane, thereby first, second, third expansion glue (2,3,4) is connected as a single entity.
Be preferably, the thickness of described the first expansion glue (2) is greater than the thickness of the second expansion glue (3).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 need in the forward and backward plane of support frame, adhere to the expansion glue that one deck is thin, just can guarantee adhesiving effect.
Installation for convenience of sound insulating seal pad is provided with the buckle (1b) being connected with vehicle body on described support frame (1).
The beneficial effects of the utility model: by set up the second expansion glue in the forward and backward plane of support frame, and the 3rd expansion glue of setting up the forward and backward plane of perforation support frame, and be connected as a single entity with existing the second expansion glue, thereby the outside face that has guaranteed 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 situation about coming off or moulding is bad; In addition, from the acoustic efficiency of whole sound insulating seal pad, because former support frame inside is also distributed with expansion glue now, better to the blocking-up of Air Flow in bodywork cavity and blockage effect.
Accompanying drawing explanation

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.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Shown in Fig. 3 and 4, a kind of for the sound insulating seal pad in auto body cavity, by support frame 1, expansion glue, formed.Support frame 1 comprises frontal plane, back plane and circumferential side wall.In the circumferential side wall of support frame 1, be stained with the first expansion glue 2 that thickness equates, support frame 1 is generally resistant to elevated temperatures nylon material.The above is with existing consistent for the sound insulating seal mat structure in auto body cavity.
Difference is: in the forward and backward plane of support frame 1, be stained with the second expansion glue 3 that thickness equates, have the intercommunicating pore 1a that connects forward and backward plane on support frame 1, 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 3rd expansion glue 4 is connected the second expansion glue 3 in forward and backward plane, thereby first, second, third expansion glue 2,3,4 is connected as a single entity, thereby makes the outside face of whole support frame 1 be inflated glue parcel.
Preferably, the thickness of the first expansion glue 2 is greater than the thickness of the second expansion glue 3.
Installation for convenience of sound insulating seal pad is provided with the buckle 1b being connected with vehicle body on support frame 1, also can adopt other interface arrangments to be connected with vehicle body.
