Detailed Description

In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.

The utility model discloses can only realize one-way restraint to current bypass seal structure, can't guarantee the problem of sealed effect, provide a bypass seal structure, carry out two-way restraint to the foaming direction through two-layer skeleton, improve leakproofness and whole bypass seal structure's rigidity and sound insulation performance.

As shown in fig. 2 to 4, the bypass sealing structure according to the embodiment of the present invention includes: fixing a framework 1; at least one first buckle 2 arranged on a first side surface of the fixing frame 1, wherein the first buckle 2 comprises a protruding buckling surface 21, and a predetermined space is formed between the buckling surface 21 and the first side surface; the second buckle 5 is arranged at the end part of the fixed framework 1 and is connected with a metal plate of an automobile body; and a movable framework 3 disposed in the predetermined space between the fixed framework 1 and the clamping surface 21, and disposed parallel to the fixed framework 3; the foaming layer 4 is arranged between the fixed framework 1 and the movable framework 3; the foaming layer 4 foams around the fixed frame 1 until the movable frame 3 abuts against the clamping surface 21.

In this embodiment, the movable frame 3 disposed in the predetermined space between the fixed frame 1 and the engaging surface 21 can move along the normal direction of the fixed frame 1 until abutting against the engaging surface 21 of the first engaging member 2. Therefore, when the foaming layer 4 between the fixed frame 1 and the movable frame 3 foams under high temperature conditions as shown in fig. 5, the foaming layer foams along three directions indicated by arrows, wherein the foaming along the normal direction of the fixed frame 1 can push the movable frame 3 to move until the movable frame 3 abuts against the engaging surface 21 of the first engaging member 2. Because of the limitation of the clamping surface 21, the movable framework 3 can not move any more, although the foaming layer 4 can not foam along the normal direction of the fixed framework 1, the foaming layer 4 can still foam along the direction parallel to the plane of the fixed framework 1, and the whole cavity is sealed.

In conclusion, the bypass sealing structure of the embodiment realizes foaming restraint of the normal direction of the fixed framework when the foaming layer is foamed through the movable framework and the first buckle capable of clamping the movable framework, so that the whole cavity is sealed, good sealing performance is formed, and meanwhile, due to the fact that the structure of the double-layer framework improves the sound insulation performance of the bypass sealing structure, the noise, vibration and sound vibration roughness performance of the whole vehicle NVH can be improved.

As shown in fig. 4, the first buckle 2 includes a first peripheral contour portion 22 connected to the first side surface and a second peripheral contour portion 23 connected to the first peripheral contour portion 22, wherein the second peripheral contour portion 23 protrudes from the first peripheral contour portion 22, and an end surface of the second peripheral contour portion 23 connected to the first peripheral contour portion 22 is formed as the buckling surface 21.

In addition, the bypass seal structure of the above embodiment is connected to the automobile body sheet metal through the second buckle 5 shown in fig. 3, but is not stable and is easy to rotate only through the connection of the second buckle, so as to be shown in fig. 2, on the basis of the above embodiment, the bypass seal structure of the embodiment of the present invention further includes: and the anti-overturning mechanism 6 is arranged on the fixed framework 1.

The two anti-overturning mechanisms are respectively arranged on the first side face and the opposite second side face of the fixed framework 1.

After the second buckle is connected with the cooperation of automobile body panel beating draw-in groove, prevent the peripheral cooperation of upset mechanism 6 and panel beating through two, make panel beating and this bypass seal structure fitting surface obtain effective restraint, reduce the upset.

It should be appreciated that the utility model discloses bypass seal structure can set up different shapes according to the panel beating cavity structure of difference, its main part.
