DETAILED DESCRIPTION

[0028] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0030] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, the automobile fluid suppressor provided by the present invention includes a shell 10, an end pipe assembly 20 and a fluid suppression assembly 30. The end pipe assembly 20 is arranged on both sides of the shell 10, and the fluid suppression assembly 30 is arranged in the shell 10. The fluid suppression assembly 30 includes a stack 31. The stack 31 is stacked and arranged in the shell 10, and is directly connected to the automobile fluid pipeline through the end pipe assembly 20. The fluid suppression assembly can gradually divide, block, reduce the speed and shift the frequency of the fluid flowing through, thereby suppressing the turbulent energy of the fluid, achieving the purpose of reducing noise and fluid pressure changes, thereby extending the service life of the fluid pipeline, improving the acoustic shock level of the whole vehicle, and improving the smoothness of fluid pressure transmission.

[0031] Figure 5 The structure of the laminate in the embodiment of the present invention is shown in FIG. Figure 1 ; Figure 6 The structure of the laminate in the embodiment of the present invention is shown in FIG. Figure 2 .

[0032] like Figure 5 and Figure 6 As shown, the laminations 31 are stacked in the housing, and the laminations 31 include a lamination body 311, a first flow hole 312, and a second flow hole 313. The first flow hole 312 and the second flow hole 313 are respectively arranged on both sides of the lamination body 311. The lamination body 311 is provided with at least one diversion hole 314, and the diversion holes 314 are evenly arranged on the lamination body 311. The lamination body 311 is cone-shaped, and the diversion holes 314 are evenly arranged on the conical surface of the lamination body 311. Figure 4As shown, when the fluid flows through the laminate 31, it flows to the second flow hole 313 through the first flow hole 312. When passing through the laminate 31, part of the flow of the fluid is gradually diverted, delayed, peeled off, and reflected back and forth in the cavity formed between the laminates 31. Attenuation tends to be eliminated. In this process, the radial fluid expands in the radial two chambers formed between the laminate 31 and the shell 10, and is blocked when passing through the diverter hole 314 on the laminate body 311, filtering, speed reduction and pressure reduction. When the axial fluid passes through the first flow hole 312, the second flow hole 313 and the axial silencing cavity formed between the laminate 31, the fluid collides forward with the inner wall of the laminate 31 to block the reflection, and the reverse and forward fluid collides with each other to convert kinetic energy into internal energy and speed reduction and pressure reduction. Part of the fluid then flows out from the first flow hole 312 and enters the next layer. The fluid is blocked by multiple layers to offset the filtration, expansion, pressure reduction and frequency shift. When the fluid flows out from the outlet, most of the frequency responses of the fluid are insensitive to the human ear and do not stimulate it. The fluid velocity and pressure are greatly reduced, thereby suppressing the fluid flow noise.

[0033] The laminations 31 are evenly arranged in the housing 10, and the volume of the cavity formed between two adjacent laminations 31 is the same; or the volume of the cavity formed between another adjacent lamination 31 gradually decreases or increases, and the diversion holes 314 between the laminations 31 can be arranged at the same angle or with deviation, so that the automotive fluid suppressor provided by the present invention can be flexibly adjusted according to actual needs, thereby improving the application range of the automotive fluid suppressor provided by the present invention.

[0034] The shell 10 is cylindrical or rectangular, and the laminate 31 is conical to match the cylindrical shell 10, or the laminate 31 is a quadrangular pyramid to match the rectangular, which can be flexibly adjusted according to actual needs, thereby improving the application range of the automotive fluid suppressor provided by the present invention. In this embodiment, the shell 10 is cylindrical, the laminate 31 is conical to match the cylindrical shell 10, the laminate body 311 is conical, and three diversion holes 314 are evenly arranged on the laminate body 311.

[0035] Figure 7 is a schematic structural diagram of a first end tube in an embodiment of the present invention; Figure 8 Schematic diagram of the structure of the second end tube in an embodiment of the present invention.

[0036] like Figure 7 and Figure 8As shown, the end pipe assembly 20 includes a first end pipe 21 and a second end pipe 22 , and the first end pipe 21 and the second end pipe 22 are respectively disposed on both sides of the housing 10 . A first liquid inlet 211 and a first liquid outlet 212 are respectively provided on both sides of the first end tube 21, the caliber of the first liquid outlet 212 is larger than that of the first liquid inlet 211, and the first liquid outlet 212 is connected to the shell 10; a second liquid inlet 221 and a second liquid outlet 222 are respectively provided on both sides of the second end tube 22, the caliber of the second liquid outlet 222 is smaller than that of the second liquid inlet 221, and the second liquid inlet 221 is connected to the shell, the first end tube 21 and the second end tube 22 divert, hysteresis block, reduce speed and shift frequency of the fluid entering or leaving the automobile fluid suppressor, so that when the fluid flows out of the automobile fluid suppressor, the speed and pressure changes of the front end of the fluid are greatly reduced, further realizing the suppression of the fluid flow noise and pressure changes, so that the first end tube 21 and the second end tube 22 also play a certain role in suppressing the turbulent energy of the fluid, further improving the turbulent energy suppression effect of the automobile fluid suppressor provided by the present invention.

[0037] When the automobile fluid suppressor provided by the present invention is used to suppress fluid turbulence, the fluid flows through the laminate 31, and flows to the second flow hole 313 through the first flow hole 312. A part of the flow of the fluid is gradually diverted, delayed, peeled off, and reflected back and forth in the cavity formed between the laminates 31 when passing through the laminate 31. The attenuation tends to be eliminated. In this process, the radial fluid expands in the radial two chambers formed between the laminate 31 and the shell 10, and is blocked when passing through the diverter hole 314 on the laminate body 311, filtering, reducing speed and pressure, and the axial fluid is When passing through the first flow hole 312, the second flow hole 313 and the axial silencer cavity formed between the laminations 31, the fluid collides with the inner wall of the laminations 31 to block the reflection, and the fluid collides with the forward fluid to convert the kinetic energy into internal energy and reduce the speed and pressure. Part of the fluid then flows out from the first flow hole 312 and enters the next layer. The fluid is blocked by multiple layers to offset the filtration expansion, pressure reduction and frequency shift. When the fluid flows out from the outlet, most of the frequency response of the fluid is insensitive to the human ear and does not stimulate the fluid. The fluid speed and pressure are greatly reduced, and the fluid flow noise is suppressed. When the fluid enters or leaves the automobile fluid suppressor, the first end tube 21 and the second end tube 22 divert, hysteresis block, reduce the speed and frequency shift the fluid, so that when the fluid flows out of the automobile fluid suppressor, the front end speed and pressure changes of the fluid are greatly reduced, and the fluid flow noise and pressure changes are further suppressed, so that the first end tube 21 and the second end tube 22 also play a certain role in suppressing the turbulent energy of the fluid, and the turbulent energy suppression effect of the automobile fluid suppressor provided by the present invention is further improved.
