It should be understood that the body side member 20 is relatively isolated from the atmospheric environment, but the body side member 20 has an intake and exhaust space.
One end of the housing 63 facing the base 61 is provided with a slot structure for mating with the boss structure 613. A plurality of strip gas ports 631 are for admitting air, the gas vent, and the joint is connected through accomplishing after mutually supporting with boss structure 613 to the draw-in groove structure.
In order to further enhance the connection sealing performance between the base 61 and the shell 63, the sealing device further comprises a sealing ring 65 for sealing and connecting the base 61 and the shell 63; a sealing groove matched with the sealing ring 65 is annularly formed on the boss structure 613. A sealed connection is achieved between the housing 63 and the base 61. This boss structure 613 and draw-in groove structure adopt the rotatory mode of pegging graft to fix casing 63 on base 61 to in order to guarantee further leakproofness and to the shutoff performance to the mounting hole, adopt in the embodiment of this application to glue stifled 62 to carry on spacingly and sealed to muffler 60, thereby make the inside that external water smoke can't get into automobile body longeron 20 through the mounting hole, the convenient assembly performance of assurance simultaneously.
Referring to fig. 3 and 4, the muffler 60 further includes a rubber plug 62 fitted between the base 61 and the sound deadening portion, which is fitted in an embedded manner inside the body side member 20 and is subjected to limit sealing by the rubber plug 62. The rubber plug 62 is made of rubber materials and has certain deformation performance.
The rubber plug 62 plays a role in positioning the muffler 60 in the muffler 60 assembly, and also needs to ensure the waterproof sealing performance of the vehicle body longitudinal beam 20, and simultaneously needs to ensure the assembly manufacturability and reduce the installation force as much as possible.
When the rubber plug 62 performs a positioning function on the sound absorber 60, the rubber plug 62 is sleeved on the boss structure 613, and a plane of the rubber plug 62 is in close contact with a plane of the boss structure 613.
Specifically, the rubber plug 62 is provided with an inner sealing lip 622 matched with the housing 63 and an outer sealing lip 621 matched with the mounting hole; the end of the inner seal lip 622 facing the housing 63 is a tapered seal surface, so that when the housing 63 applies a pushing force to the boss structure 613 of the base 61, a seal is formed between the tapered seal surface and the side wall of the housing 63, and when the slot structure and the boss structure 613 are in proper fit with each other, a pressing force is applied between the plane of the rubber plug 62 and the plane of the boss structure 613, so that the seal of the inner seal lip 622 to the housing 63 is realized.
Meanwhile, the diameter of the opening of the mounting hole is larger than that of the shell 63, so that the risk that water mist enters the vehicle body longitudinal beam 20 exists in the mounting hole, the outer sealing lip 621 seals the mounting hole, and the external water mist is effectively prevented from entering the inside of the vehicle body longitudinal beam 20. It can be seen that the inner sealing lip 622 seals against the housing 63 and the outer sealing lip 621 seals against the mounting hole. Meanwhile, the sealing ring 65 further ensures the installation sealing performance of the shell 63 and the base 61, and ensures higher waterproof fog performance under the action of multiple sealing.
Meanwhile, when the silencer 60 is positioned at the position of the mounting hole of the vehicle body longitudinal beam 20, the inner sealing lip 622 and the outer sealing lip 621 are in interference clamping connection with the mounting hole. Specifically, the inner sealing lip 622 and the outer sealing lip 621 have a staggered step therebetween. The conical sealing surface is more tightly sealed, and the dislocation step is clamped at the position of the mounting hole in an interference manner.
This is seen. The inner side and the outer side of the rubber plug 62 are provided with sealing lip structures to form 2 seals, and the middle part of the rubber plug forms a 3 rd sealing structure through interference design with the mounting hole.
