[0028] With the increasingly fierce competition in the automotive market, in-vehicle noise, vibration, and comfort have become one of the main factors affecting vehicle performance and consumer purchase desire. In-vehicle noise mainly consists of structure-borne noise caused by vehicle body vibration and air-borne noise. The body vibration noise comes from engine body vibration, road excitation, and its exhaust system, and the air noise comes from the engine body, intake system, exhaust system, cooling fan, and tires, etc. Among them, the noise of the intake system is the main source of in-vehicle noise. How to optimize the structure of the intake system and improve the noise reduction effect has become an urgent problem in this field.

[0029] Reference is made below to Figures 1 - 3 describe a longitudinal beam structure for a vehicle according to an embodiment of the present utility model.

[0030] The longitudinal beam structure 1 for a vehicle according to the present utility model includes a beam body 11, a reinforcing partition 12, and a sealing partition. A receiving cavity is formed in the beam body 11; the reinforcing partition 12 extends in the same direction as the beam body 11 and is received in the receiving cavity. Both sides of the reinforcing partition 12 in the width direction are in contact with the inner wall of the receiving cavity. The reinforcing partition 12 divides the receiving cavity into a first channel 111 and a second channel 112; the sealing partition is disposed at both ends of the beam body 11 and closes the first channel 111; an air filter 13 and an air intake pipe 14 are provided on the vehicle. The intake pipe 131 of the air filter 13 is communicated with the first channel 111; the air intake pipe 14 is disposed on the beam body 11 and communicates the first channel 111 with the outside. The air intake pipe 14 and the intake pipe 131 of the air filter 13 are spaced apart in the extending direction of the first channel 111.

[0031] Specifically, a receiving cavity is formed in the beam body 11. The reinforcing partition 12 is disposed in the receiving cavity. Both sides of the reinforcing partition 12 in the width direction are in contact with the inner wall of the receiving cavity to support the inside of the beam body 11 and improve the structural strength of the beam body 11. The reinforcing partition 12 extends along the length direction of the beam body 11 and divides the receiving cavity into a first channel 111 and a second channel 112 in the height direction. Wherein, sealing partitions are respectively disposed at both ends of the beam body 11 to seal the first channel 111 to ensure the airtightness of the first channel 111. The first channel 111 serves as an intake channel of the air filter 13. An air intake pipe 14 that communicates the first channel 111 with the outside is disposed on the beam body 11. The intake pipe 131 of the air filter 13 is also communicated with the first channel 111. Air enters the first channel 111 through the air intake pipe 14 and flows into the air filter 13 through the intake pipe 131. A resonance cavity can be disposed in the intake pipe 131 of the air filter 13 to eliminate low-frequency noise. The intake pipe 131 of the air filter 13 and the air intake pipe 14 are spaced apart in the extending direction of the first channel 111. By increasing the distance between the intake pipe 131 and the air intake pipe 14, the volume of the first channel 111 is increased to improve the noise reduction amount of the intake system. The larger the volume of the first channel 111, the wider the frequency band covered by the intake system, the greater the air transmission noise loss, the higher the noise reduction amount of the intake system, and the smaller the noise generated by the intake system.

[0032] According to the longitudinal beam structure 1 of the present utility model, a receiving cavity is formed inside the beam body 11. A reinforcing partition 12 is arranged in the receiving cavity to support the inner wall of the beam body 11, improving the structural strength of the beam body 11. The reinforcing partition 12 divides the receiving cavity into a first channel 111 and a second channel 112. The first channel 111 is sealed by arranging a sealing partition. The intake pipe 131 of the air filter 13 and the induction pipe 14 are respectively communicated with the first channel 111. Air enters the first channel 111 through the induction pipe 14 and then flows into the air filter 13 through the intake pipe 131, eliminating low-frequency noise. By arranging the first channel 111 in the receiving cavity for gas flow, the intake volume of the intake system is increased, the loss of noise transmission is improved, thereby improving the noise reduction amount of the intake system and reducing the noise generated by the intake system.

[0033] According to some embodiments of the present utility model, the sealing partition includes a first partition 151 and a second partition 152. The first partition 151 is arranged at one end of the reinforcing partition 12 and is perpendicular to the reinforcing partition 12. The outer periphery of the first partition 151 is connected to the inner wall of the receiving cavity. The second partition 152 is received in the first channel 111 and is arranged between the upper surface of the reinforcing partition 12 and the beam body 11. The outer periphery of the second partition 152 is connected to the inner wall of the beam body 11 and the reinforcing partition 12.

[0034] Specifically, the first partition 151 is arranged at one end of the reinforcing partition 12 and extends perpendicular to the reinforcing partition 12. The outer periphery of the first partition 151 is connected to the inner wall of the receiving cavity to form a sealing surface perpendicular to the length direction of the beam body 11 at one end of the first channel 111. The second partition 152 is received in the first channel 111 and is arranged between the upper surface of the reinforcing partition 12 and the beam body 11. The outer periphery of the second partition 152 is respectively connected to the inner wall of the beam body 11 and the reinforcing partition 12 to seal the other end of the first channel 111. By arranging the first partition 151 and the second partition 152 to seal the first channel 111, the sealing performance of the first channel 111 is ensured. Among them, the induction pipe 14 is arranged on the side of the first partition 151 facing the second partition 152, and the intake pipe 131 is arranged on the side of the second partition 152 facing the first partition 151. The induction pipe 14 and the intake pipe 131 are respectively communicated with the first channel 111, expanding the volume of the intake system, increasing the air noise transmission loss, and reducing the noise generated by the intake system.

[0035] According to some embodiments of the present utility model, the reinforcing partition 12 includes a main body portion 121 and a lapping plate 122. The main body portion 121 extends in the width direction to divide the first channel 111 and the second channel 112 in the height direction. The lapping plates 122 are arranged on both sides of the main body portion 121 in the width direction and extend along the height. The lapping plates 122 are adapted to be connected to the inner wall of the beam body 11.

[0036] Specifically, the main body portion 121 extends along the width direction of the beam body 11 and is connected to the inner wall of the accommodation cavity, so as to separate the first channel 111 and the second channel 112 in the height direction. The main body portion 121 cooperates with the first partition plate 151 and the second partition plate 152 to seal the first channel 111. The main body portion 121 extends along the width direction and supports the side walls of the beam body 11 in the width direction, improving the structural strength of the beam body 11 and preventing the beam body 11 from bending. Lapping plates 122 are respectively arranged on both sides of the main body portion 121 in the width direction. The lapping plates 122 extend along the height direction and are connected to the inner walls of the beam body 11 in the width direction, so as to increase the contact area between the reinforcing partition 12 and the inner wall of the beam body 11, and make the installation of the reinforcing partition 12 more stable.

[0037] According to some embodiments of the present invention, a reinforcing convex portion 1211 protruding in the height direction is formed on the main body portion 121.

[0038] Specifically, the reinforcing convex portion 1211 protrudes from the main body portion 121 in the height direction, increasing the overall thickness of the reinforcing partition 12. When subjected to external forces, the reinforcing convex portion 1211 can disperse the stress to a larger area, reducing the concentration of local stress, thereby improving the load-bearing capacity of the entire structure and enabling the reinforcing partition 12 to better resist deformation.

[0039] According to some embodiments of the present invention, the longitudinal beam structure 1 further includes a reinforcing member 16. The reinforcing member 16 is arranged in the second channel 112 and extends along the height direction. The reinforcing member 16 is supported between the bottom of the beam body 11 and the reinforcing partition 12.

[0040] Specifically, the reinforcing member 16 extends along the height direction to support the reinforcing partition 12, preventing the reinforcing partition 12 from sinking or deforming when subjected to external forces. Moreover, the reinforcing member 16 can also enhance the strength and stiffness of the beam body 11 in the area of the second channel 112, effectively resist external forces, and improve the load-bearing capacity and stability of the entire longitudinal beam structure 1.

[0041] According to some embodiments of the present invention, a lapping flange 161 adapted to abut against the reinforcing convex portion 1211 is arranged on the reinforcing member 16.

[0042] Specifically, by arranging the lapping flange 161 on the reinforcing member 16 to abut against the reinforcing convex portion 1211, the contact area between the reinforcing member 16 and the reinforcing partition 12 is increased. The lapping flange 161 is in close contact with the reinforcing convex portion 1211, forming a stable support structure, which is beneficial to reducing the loosening or displacement caused by vibration or other external forces, thereby improving the stability and reliability of the entire longitudinal beam structure 1. The lapping flange 161 can disperse the stress to a larger area, reducing the concentration of local stress, thereby improving the load-bearing capacity of the longitudinal beam structure 1.

[0043] According to some embodiments of the present utility model, the reinforcing members 16 are configured as multiple and are spaced apart in the extending direction of the reinforcing partition 12.

[0044] Specifically, by arranging multiple reinforcing members 16 at intervals in the extending direction of the reinforcing partition 12, a plurality of support points are added in the second channel 112, and the multiple reinforcing members 16 respectively support the reinforcing partition 12 to prevent it from sinking or deforming.

[0045] According to some embodiments of the present utility model, the longitudinal beam structure 1 further includes a sound-absorbing member 17, and the sound-absorbing member 17 is disposed in the first channel 111.

[0046] Specifically, by arranging the sound-absorbing member 17 in the first channel 111 to sound-absorb the air entering the first channel 111, the sound-absorbing member 17 can be configured as foam, sound insulation cotton, etc. These materials can absorb sound energy, thereby reducing noise. The sound-absorbing member 17 can be disposed adjacent to the air intake pipe 14. After the air enters the first channel 111 through the air intake pipe 14, the noise is preliminarily filtered by the sound-absorbing member 17, and then passes through the air filter 13 and the resonance cavity to achieve noise reduction, further reducing the noise generated by the intake system.

[0047] According to some embodiments of the present utility model, the sound-absorbing member 17 is configured as a sound insulation board, and the sound insulation board is received in the first channel 111 and is configured as multiple spaced apart between the intake pipe 131 and the air intake pipe 14.

[0048] Specifically, the sound-absorbing member 17 is configured as a sound insulation board, and the sound insulation board can be configured as porous materials, foam plastics, rubber, etc., which is beneficial to absorbing sound energy, thereby achieving noise reduction. The sound insulation board is configured as multiple and is spaced apart between the intake pipe 131 and the intake pipe 131. When the air flow passes through the first channel 111, it is blocked by the multiple sound insulation boards, thereby effectively reducing the propagation of noise.
