When the base 61 and the muffler are in a state of being perpendicular to each other, the base 61 has an L-shaped structure; one end of the base 61 of the L-shaped structure is connected to the free end of the second connecting pipe 40b, i.e., the end remote from the filter 50. The other end of the base 61 of the L-shaped structure is engaged with the muffler.
When the base 61 is specifically and conveniently connected with the second connecting pipeline 40b, a bamboo joint structure 611 for connecting with the second connecting pipeline 40b is arranged at one end of the base 61; the second connecting pipeline 40b is inserted into the bamboo joint structure 611 and is fixed by a plurality of locking cards, the operation is convenient, and the second connecting pipeline 40b is tightly clamped with the base 61.

The boss structure 613 and the bamboo joint structure 611 are perpendicular to each other, and the silencer is sleeved on the boss structure 613 through the boss structure 613, and the sealing type clamping connection is completed, so that the gas is conveyed to the silencer by the base 61 after the gas inlet and outlet actions pass through the filter.
Referring also to fig. 3, in the embodiment of the present application, the location of the noise reduction portion is located inside the vehicle body side member 20, and when the noise reduction portion is specifically assembled inside the vehicle body side member 20, a mounting hole having a diameter larger than the noise reduction portion is formed in the vehicle body side member 20, and a planar structure 612 for pushing the noise reduction portion along the mounting hole into the vehicle body side member 20 is provided on the vertical surface of the base 61. The installer can hold the planar structure 612 of the base 61 by the palm, push the base 61 horizontally, enable the silencing part of the base 61 to enter the interior of the longitudinal beam 20 of the car body, and apply thrust more conveniently.
The silencer comprises: a case 63 and a noise damping cotton 64 fitted inside the case 63; the silencing cotton 64 is cylindrical sponge, and a plurality of strip-shaped air ports 631 are formed in the shell 63 along the circumferential direction of the shell; the silencing cotton 64 seals the plurality of strip-shaped air ports 631, and the plurality of strip-shaped air ports 631 are air inlet and air outlet ports, so that when the air compressor 30 performs air inlet and outlet actions, the air inlet and outlet bodies suck external air or discharge air along the air inlet and outlet ports through the silencing cotton 64. It should be understood that the body side member 20 is relatively isolated from the atmosphere, 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 clamping groove structure in plug-in fit with the boss structure 613. The plurality of strip-shaped air ports 631 are air inlet and air outlet, and the clamping groove structure is matched with the boss structure 613 to complete clamping connection.
And in order to further enhance the connection tightness between the base 61 and the housing 63, a sealing ring 65 for sealing connection between the base 61 and the housing 63 is further included; the boss structure 613 is provided with a seal groove matched with the seal ring 65. The housing 63 is in sealing connection with the base 61. The boss structure 613 and the clamping groove structure fix the shell 63 on the base 61 in a plugging and rotating mode, and in order to ensure further tightness and plugging performance of the mounting hole, the muffler 60 is limited and sealed by the glue plug 62 in the embodiment of the application, so that external water mist cannot enter the inside of the vehicle body longitudinal beam 20 through the mounting hole, and meanwhile, the convenient assembly performance is ensured.
Referring to fig. 3 and 4, the muffler 60 further includes a block 62 fitted between the base 61 and the muffler portion, the muffler portion is fitted inside the body side member 20 in an embedded manner, and the block 62 performs a limit seal. The rubber plug 62 is made of rubber materials and has certain deformation performance.
The glue plug 62 plays a role in positioning the muffler 60 in the assembly of the muffler 60, ensures the waterproof sealing property of the longitudinal beam 20 of the vehicle body, ensures the assembly manufacturability, and reduces the installation force as much as possible.
When the glue plug 62 completes the positioning function on the sound absorber 60, the glue plug 62 is sleeved on the boss structure 613, and the plane of the glue plug 62 is in close contact with the plane of the boss structure 613.
Specifically, the glue plug 62 is provided with an inner sealing lip 622 that cooperates with the housing 63, and an outer sealing lip 621 that cooperates with the mounting hole; the inner sealing lip 622 is tapered sealing surface toward one end of the housing 63, so that a seal is formed between the tapered sealing surface and the side wall of the housing 63 while the housing 63 applies thrust to the boss structure 613 of the base 61, and when the clamping groove structure and the boss structure 613 are matched in place, an abutting force is applied between the plane of the glue plug 62 and the plane of the boss structure 613, so that the sealing of the housing 63 by the inner sealing lip 622 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 external water mist is effectively prevented from entering the inside of the vehicle body longitudinal beam 20. It can be seen that inner sealing lip 622 seals housing 63 and outer sealing lip 621 seals the mounting hole. Meanwhile, the sealing ring 65 further ensures the installation tightness of the shell 63 and the base 61, and ensures higher water mist resistance under the multiple sealing effect.
Meanwhile, when the muffler 60 is positioned at the mounting hole of the vehicle body side member 20, the inner seal lip 622 and the outer seal lip 621 are engaged with the mounting hole by interference. Specifically, there is a step offset between the inner sealing lip 622 and the outer sealing lip 621. The conical sealing surface is sealed more tightly, and the dislocation step interference fit is in the mounting hole position.
This is visible. The inner side and the outer side of the glue plug 62 are designed with sealing lip structures to form 2 seals, and meanwhile, the middle part forms a 3 rd sealing structure through interference design with the mounting holes.
With continued reference to fig. 4, fig. 4 is a schematic cross-sectional structure of a muffler 60 according to an embodiment of the present application. When the silencing part of the silencer 60 is arranged on the longitudinal beam 20 of the vehicle body for operation, the shell 63 is clamped and fixed on the boss structure 613, the glue plug 62 is pressed and fixed, an operator holds the planar structure 612 of the base 61, and the shell 63 is partially positioned in the mounting hole; the silencer 60 is pushed forward in a flat way, so that the glue plug 62 passes through the dislocation step after being forced to deform, at the moment, the outer sealing lip 621 seals the mounting hole, and the dislocation step and the mounting hole are in interference fit, so that the position stability of the silencer 60 is ensured; therefore, the glue plug 62 plays a role in positioning the muffler 60 in the assembly of the muffler 60, ensures the waterproof tightness of the longitudinal beam 20 of the vehicle body, ensures the assembly manufacturability and reduces the installation force as much as possible.
In addition, at least two deformation avoiding grooves 623 are formed in the inner wall of the rubber plug 62 in an annular manner. Providing a space for avoiding deformation of the rubber plug 62, and effectively reducing the insertion force of the muffler 60 when being matched with the mounting hole.

The stopper 62 is formed to be axially limited to prevent the damper 60 from moving when it is mounted to the side member 20.
From the above, it can be seen that the muffler 60 is composed of a base 61, a housing 63, a plug 62, a seal 65 and a noise damping cotton 645.
The base 61 is of an L-shaped structure, one end of the base 61 is provided with a boss structure 613 which is matched with the shell 63 in a clamping way, and the other end of the base 61 is provided with a bamboo joint structure 611 which is connected with a pipeline. In order to facilitate assembly personnel installation in the production line, the middle part is designed with a flat planar structure 612 which is convenient for pushing and pressing the palm into the installation hole of the longitudinal beam 20 of the vehicle body.
The casing 63 is provided with a plurality of strip-shaped air ports 631 which are air inlet and outlet ports; the tail of the shell 63 is provided with a clamping groove structure which is clamped with the base 61. Thereby the clamping groove structure is matched with the boss structure 613 to complete the clamping connection.
The glue plug 62 plays a role in positioning the muffler 60 in the assembly of the muffler 60, ensures the waterproof sealing property of the longitudinal beam 20 of the vehicle body, ensures the assembly manufacturability, and reduces the installation force as much as possible. The plug 62 is made of deformable rubber material.
The inner side and the outer side of the rubber plug 62 are designed with sealing lip structures to form 2 seals, and meanwhile, the middle part of the rubber plug forms a 3 rd sealing structure through interference design with a vehicle body hole.
