Description

Technical Field

[0001] This utility model relates to the field of automotive damping plate technology, and in particular to an automotive damping plate that can be foamed and filled. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands of consumers for vehicle comfort, safety, and fuel economy, the design of automotive components for vibration damping, sound insulation, and lightweighting has become increasingly important. During vehicle operation, engine operation, uneven road surfaces, tire friction, and body structure vibrations all generate noise and vibration. These not only affect the driving experience but can also cause fatigue damage to vehicle components in the long run. Therefore, damping plates are widely used in automobile manufacturing to absorb and attenuate vibration energy, reduce noise transmission, and improve the vehicle's NVH performance.

[0003] In existing technologies, most automotive damping panels have a simple structural design, and their function is often limited to basic sound absorption or vibration reduction. This simple structure limits the damping panel's ability to cope with complex sound and vibration coupling problems, resulting in less than ideal noise reduction effects in practical applications, making it difficult to meet the increasingly demanding requirements for quietness in modern automobiles.

[0004] Therefore, those skilled in the art have provided a foamable filling automotive damping plate to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a foamable automotive damping plate. This damping plate uses a combination design of frame and honeycomb blocks, and utilizes the through holes on the honeycomb blocks to ensure that the foam filling material is evenly injected and fills the structure. This allows the honeycomb blocks, through holes, and filling material to work together to effectively suppress vibration and noise, significantly improve the overall damping performance and sound absorption effect of the plate, and significantly improve the comfort and quietness of the car interior.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foamable automotive damping plate includes a frame, in which multiple honeycomb blocks are evenly spaced inside the frame, and foam filler is filled between and inside the multiple honeycomb blocks. Microporous plates are provided at the upper and lower ends of the frame, and a substrate layer is provided on one side of each of the two microporous plates.

[0008] Through the above technical solution, the damping plate uses a combination design of frame and honeycomb blocks. The through holes on the honeycomb blocks ensure that the foam filling material is evenly injected and fills the structure, so that the honeycomb blocks, through holes and filling material can work together to effectively suppress vibration and noise, greatly improve the overall damping performance and sound absorption effect of the plate, and significantly improve the comfort and quietness of the car interior.

[0009] Furthermore, an injection hole is provided in the middle of one end face of the frame;

[0010] The above technical solution allows for precise and efficient injection of foamed filler into the honeycomb block during the manufacturing process, ensuring a smooth and controllable filling process and improving production efficiency and filling quality.

[0011] Furthermore, through holes are provided in the middle of the multiple end faces of the honeycomb block;

[0012] Through the above technical solution, the multi-sided through holes ensure that the foamed filler can penetrate evenly from multiple directions and fill the complex internal structure of the honeycomb block, avoiding filling dead corners, making the synergistic effect of the honeycomb block and filler better, and improving the overall damping performance.

[0013] Furthermore, the substrate layer is made of butyl rubber material;

[0014] Through the above technical solution, butyl rubber material has excellent high damping characteristics. As a substrate layer, it can effectively dissipate vibration energy and significantly enhance the vibration reduction and noise reduction capabilities of the damping plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. The present invention proposes a foamable filling automotive damping plate. The damping plate uses a combination design of frame and honeycomb blocks to ensure that the foam filling material is evenly injected and fills the structure through the through holes on the honeycomb blocks. This allows the honeycomb blocks, through holes and filling material to work together to effectively suppress vibration and noise, greatly improve the overall damping performance and sound absorption effect of the plate, and significantly improve the comfort and quietness of the car interior.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Reference Figure 1-4 This utility model provides a specific embodiment: a foamable automotive damping plate, including a frame 1, a plurality of honeycomb blocks 2 are evenly spaced inside the frame 1, and foam filler 4 is filled between and inside the plurality of honeycomb blocks 2, and microporous plates 6 are provided at the upper and lower ends of the frame 1, and a substrate layer 7 is provided on one side end face of the two microporous plates 6.

[0025] The damping plate uses a combination design of frame 1 and honeycomb block 2. The through holes 3 on the honeycomb block 2 ensure that the foam filler 4 is evenly injected and fills the structure, so that the honeycomb block 2, through holes 3 and filler can work together to effectively suppress vibration and noise, greatly improve the overall damping performance and sound absorption effect of the plate, and significantly improve the comfort and quietness of the car interior.

[0026] An injection hole 5 is provided in the middle of one end face of the frame 1. The injection hole 5 facilitates the precise and efficient injection of foam filler 4 into the honeycomb block 2 during the manufacturing process, ensuring a smooth and controllable filling process, improving production efficiency and filling quality. Through holes 3 are provided in the middle of multiple end faces of the honeycomb block 2. The multiple through holes 3 ensure that the foam filler 4 can penetrate evenly from multiple directions and fill the complex internal structure of the honeycomb block 2, avoiding filling dead corners, making the synergistic effect of the honeycomb block 2 and the filler better, and improving the overall damping performance. The substrate layer 7 is made of butyl rubber material. Butyl rubber material has excellent high damping characteristics. As the substrate layer 7, it can effectively dissipate vibration energy and significantly enhance the vibration reduction and noise reduction capabilities of the damping plate.

[0027] Working principle: When the car generates vibration and noise, the energy is first transferred to the substrate layer 7, which absorbs part of the energy due to the damping properties of the material itself. Subsequently, the vibration and sound waves enter the cavity structure composed of honeycomb blocks 2, where the honeycomb structure itself performs initial scattering and reflection of the sound waves. At the same time, the foam filler 4, pre-injected and solidified within the honeycomb, deforms under the action of sound waves and vibration, efficiently converting sound energy and vibration energy into heat energy for dissipation. In addition, the through holes 3 on the honeycomb blocks 2 and the microporous plates 6 on the surface further increase the path length of sound wave propagation, and utilize the principle of impedance mismatch to effectively block and absorb noise of different frequencies, ultimately achieving an overall vibration reduction and noise reduction effect.
