However, conventional rescue vehicle designs often neglect noise reduction, resulting in high noise levels during operation, which impacts the physical and mental health of rescue workers and their work efficiency. Therefore, developing an air intake noise reduction component that effectively reduces noise is particularly important. Utility Model Content

[0003] In order to solve some of the problems existing in the above-mentioned prior art, the utility model provides an air intake noise reduction component for use in a rescue vehicle to solve the deficiencies existing in the prior art.

[0004] To achieve the above-mentioned purpose, the utility model provides an air intake noise reduction component for use in a rescue vehicle, comprising a rescue vehicle body, the rescue vehicle body comprising a chassis, a vehicle body is arranged on the chassis, a driver's cab is arranged at the front end of the vehicle body, and a carriage structure is arranged at the rear end of the vehicle body, a rest control cabin, an engine compartment and a cargo compartment are sequentially arranged on the carriage structure, an exhaust noise reduction area is arranged on one side of the engine compartment above the cargo compartment, and an electric shutter air intake noise reduction device is arranged in the exhaust noise reduction area.

[0005] As a further improvement of the present invention, in order to improve space utilization, realize convenient control of the noise reduction device, and improve the convenience of operation, the rest control cabin is provided with a double-layer folding bed for personnel to rest, an equipment control cabinet and a folding workbench. The double-layer folding bed is arranged on one side of the rest control cabin, and the equipment control cabinet is arranged above the equipment control cabinet. The equipment control cabinet is electrically connected to the item cabin and the electric shutter air inlet noise reduction device.

[0006] As a further improvement of the present invention, in order to achieve flexible adjustment of the noise reduction louver structure, facilitate the adjustment of the air intake volume and noise reduction effect according to actual needs, and enhance the stability and durability of the device, the electric louver air intake noise reduction device includes a circular frame structure, and the upper and lower ends of the circular frame structure are respectively provided with a rotating shaft seat, and the rotating shaft seat is provided with several groups, and the rotating shaft seat is interspersed with the circular frame structure to provide several groups of rotating shafts, and the noise reduction louver structure is provided on the rotating shaft.

[0007] As a further improvement of the present invention, in order to significantly improve the structural strength and wind pressure resistance of the noise reduction louvers, ensure the stability and reliability of the noise reduction louvers during long-term use, and help improve the noise reduction effect, the noise reduction louver structure includes arc plates arranged on the rotating shaft on both sides of the circular frame structure, and a rectangular plate is arranged on the rotating shaft between the two groups of arc plates. The arc plates and the rectangular plates are also provided with longitudinal reinforcement structures and transverse reinforcement structures.

[0008] As a further improvement of the present invention, in order to further improve the noise reduction effect, achieve tight closure, prevent noise leakage, and ensure the maximization of the noise reduction effect, micro-perforated plates are also provided on the arc plates and rectangular plates. The micro-perforated plates are set to a certain thickness and are filled with glass wool. A joint structure is also provided between adjacent arc plates and rectangular plates to achieve closure.

The microperforated panels allow air circulation while their small pores effectively absorb and disperse noise energy. Glass wool, a highly effective sound-absorbing material, further absorbs noise that enters through the microperforated panels, enhancing the noise reduction effect. The joint structure between the circular and rectangular panels ensures a tight seal when the louver structure is closed, preventing noise leakage.

[0013] The pivot seat beneath the circular frame is connected to the connecting rod via connecting ribs, forming a stable support structure. This design enhances the overall stability and load-bearing capacity of the electric shutter air intake noise reduction device, ensuring stable operation during vehicle operation. The connecting rod controls the opening and closing of the four sets of circular and rectangular panels.

[0014] The beneficial effects of the present invention are embodied in the following aspects:

[0015] Highly efficient noise reduction:

[0016] By creating an exhaust noise reduction zone above the cargo bay and near the engine compartment, and installing a motorized louver inlet noise reduction device within this zone, this utility model effectively isolates and reduces noise generated by the engine compartment.

This design not only facilitates control of air intake and noise reduction effectiveness, but also enhances the adaptability and practicality of the device. When more ventilation is required, the louvers can be opened appropriately; when stronger noise reduction is required, the louvers can be closed more tightly.

[0019] Stable structure:

[0020] The arc-shaped and rectangular panels of the noise-reducing louver structure feature longitudinal and transverse reinforcements, significantly enhancing the structural strength and wind pressure resistance of the louvers. Furthermore, the pivot seat beneath the circular frame, combined with connecting ribs and rods, forms a stable support structure, enhancing the overall stability and load-bearing capacity of the electric louver air intake noise reduction device and ensuring its stability and reliability over long-term use.
