Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an air filter intake pipe bracket and a vehicle. Background Art

[0002] For fuel vehicles, when the engine is running, air passes through the intake system to the air filter intake pipe and finally to the engine. The noise generated by the intake system is the main source of noise inside the vehicle. Due to the characteristics of the overall layout of light truck systems, the intake system is mostly arranged under the passenger seat, very close to the cab, so the radiated noise and structural vibration generated by the intake system will pass through the vehicle body, causing serious NVH problems and affecting the ride comfort of the entire vehicle.

[0003] Since the air intake pipe of light trucks is installed at a higher position and is longer, the air filter intake pipe will be fixed to the rear panel of the vehicle body with vibration isolation pads and bolts. However, the existing air intake pipe bracket has insufficient rigidity and low modal frequency, which can easily cause resonance between the bracket and the rear panel, producing a strong resonant roar. People in the car can clearly feel the loud noise, which reduces the user's driving experience. Utility Model Content

[0025] See also Figures 1 to 3 The present application exemplarily provides an air filter intake pipe bracket, comprising:

[0026] The bracket body 9 includes a first mounting surface 1, the first mounting surface 1 is connected to the vehicle body, the middle part of the first mounting surface 1 protrudes upward to form a boss structure on the bracket body 9, and a second mounting surface is arranged on the boss structure, the middle part of the second mounting surface is a recessed surface 4, the recessed surface 4 forms a mounting position for accommodating the intake pipe 10, and the two sides of the recessed surface 4 are connecting surfaces 2 for connecting with the intake pipe 10.

[0027] The bracket body 9 is installed on the vehicle body through the first mounting surface 1, and the intake pipe 10 is fitted and contacted with the connecting surface 2, so that the intake pipe 10 is assembled on the mounting position formed by the recessed surface 4 for positioning, and the installation of the intake pipe 10 is completed, thereby improving the dynamic stiffness of the intake pipe bracket, reducing the risk of coupling between the intake pipe bracket and the intake system acoustic cavity mode, the vehicle body rear panel and the vehicle interior acoustic cavity mode, effectively reducing the resonance between the intake pipe bracket and the vehicle body rear panel sheet metal 7, reducing the noise generated, and improving the user's driving comfort.

[0028] It should be noted that, in this embodiment, please refer to Figure 4 , Figure 4The IPI curve diagrams before and after optimization of the air filter intake pipe bracket are as follows. The intake pipe bracket provided in the present application has a smoother curve compared to the existing intake pipe bracket, which reduces the risk of coupling between the intake pipe bracket and the intake system acoustic cavity mode, the rear panel of the vehicle body, and the acoustic cavity mode inside the vehicle.

[0029] It can be understood that, see Table 1 and Figure 5 Table 1 shows the optimization results of dynamic stiffness of air filter intake pipe bracket before and after optimization. Figure 5 The comparison chart of the low-frequency roaring noise in the car before and after the optimization of the air filter intake pipe bracket shows that the dynamic stiffness of the intake pipe bracket is increased from 871N / mm to 4640N / mm, and the dynamic stiffness is increased by 433%, which effectively improves the stiffness of the intake pipe bracket. At the same time, the bracket mode is increased from 90.5Hz to above 300Hz, avoiding the second-order excitation frequency (roaring point) of the engine at about 2750rpm. The acceleration roar in the car is reduced by 6dB, which has a significant effect on the noise reduction of the acceleration roar in the car and improves the driving comfort of the vehicle.
