Description

Technical Field

[0001] This utility model relates to the field of automotive engineering technology, and in particular to a shock-absorbing pad for automotive engine suspension. Background Technology

[0002] In modern automotive engineering, the engine mounting system is an important component to ensure the smoothness and comfort of vehicle driving. As a key component of this system, the engine mounting damping pads mainly support the engine and transmission, while reducing the transmission of engine vibration and noise to the vehicle body.

[0003] Traditional damping pads rely primarily on the sound insulation properties of the material itself for their sound insulation performance. They are not very effective at isolating high-frequency and low-frequency noise, especially when the engine is running at high speed. High-frequency noise can easily penetrate the pads and enter the cabin, affecting the quietness of the interior. Furthermore, ordinary rubber materials are prone to aging over long-term use, leading to a decline in damping and sound insulation performance. In addition, these materials are less resistant to chemical corrosion and environmental factors, further shortening the lifespan of the pads. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a car engine suspension damping pad.

[0005] This utility model is achieved by the following technical solution: a car engine suspension shock absorber pad, including a pad body, a sound insulation arc plate fixedly connected to the outer surface of the pad body, a conical sound insulation hole opened on the surface of the sound insulation arc plate, and an anti-corrosion layer provided on the outer surface of the pad body.

[0006] The above technical solutions achieve both shock absorption and sound insulation, improving noise reduction in the car engine compartment while ensuring the durability of the pad body under harsh working conditions.

[0007] As a further improvement to the above solution, two sound-insulating arc plates are provided, and the two sound-insulating arc plates are respectively fixedly connected to both sides of the outer surface of the soft pad body.

[0008] The above technical solutions enhance sound insulation, further reduce engine noise transmission into the passenger compartment, and improve the quietness of the vehicle interior.

[0009] As a further improvement to the above solution, the soft pad body is a composite rubber soft pad, and the sound insulation arc plate is a foamed rubber sound insulation arc plate.

[0010] As a further improvement to the above solution, the number of conical sound insulation holes is set to several, and the several conical sound insulation holes are evenly distributed at equal intervals on the outer surface of the sound insulation arc plate.

[0011] As a further improvement to the above solution, the anti-corrosion layer is an epoxy resin anti-corrosion layer, and a mounting base is fixedly connected to the lower surface of the soft pad body.

[0012] The above technical solutions enhance the corrosion resistance of the cushion body and extend its service life.

[0013] As a further improvement to the above solution, a positioning block is fixedly connected to the surface of the mounting base, and a preset bolt groove is provided on the surface of the positioning block.

[0014] As a further improvement to the above solution, the number of positioning blocks is set to four, and the four positioning blocks are respectively fixedly connected to the four corners of the mounting base surface.

[0015] The above technical solutions further improve installation stability and ensure the reliability of the pad during use.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by setting up double-sided sound-insulating arc plates and conical sound-insulating holes, can effectively block and weaken noise propagating from different directions, expanding the sound insulation coverage. Furthermore, the reflection and interference of sound waves within the conical holes further consume noise energy, significantly reducing noise propagation. The porous structure of the foamed rubber sound-insulating arc plates can absorb and scatter sound waves, working in conjunction with the conical sound-insulating holes to effectively attenuate sound waves of different frequencies, increasing the sound insulation frequency range and achieving wideband noise reduction. This avoids the problems of poor sound insulation effect and limited noise reduction in specific directions or frequencies of traditional shock-absorbing pads, providing a quieter and more comfortable driving environment for drivers and passengers, effectively reducing engine noise interference in the vehicle interior, and improving the quietness of the vehicle interior.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Example: Please combine Figure 1-4 This embodiment of an automotive engine suspension damping pad includes a pad body 1, with a sound-insulating arc plate 2 fixedly connected to the outer surface of the pad body 1. The surface of the sound-insulating arc plate 2 has conical sound-insulating holes 3. An anti-corrosion layer 4 is provided on the outer surface of the pad body 1. As a damping component, the sound-insulating arc plate 2 fixedly connected to the outer surface of the pad body 1 can block some noise transmission. The diameter of the conical sound-insulating holes 3 decreases from the inside to the outside. When noise enters the holes, the sound waves are continuously reflected and interfered within the conical holes, and the energy is gradually consumed, thereby effectively reducing noise transmission. The anti-corrosion layer 4 can resist the erosion of the pad body 1 by external corrosive substances, extending its service life.

[0021] There are two sound insulation arc plates 2. The two sound insulation arc plates 2 are fixedly connected to both sides of the outer surface of the soft pad body 1. The two sound insulation arc plates 2 are fixed to both sides of the outer surface of the soft pad body 1 to form a double-sided sound insulation structure. Noise transmitted from different directions can be blocked and weakened by the sound insulation arc plates 2 on both sides, thus expanding the sound insulation coverage.

[0022] The soft pad body 1 is a composite rubber soft pad, and the sound insulation arc plate 2 is a foamed rubber sound insulation arc plate. The composite rubber soft pad has good elasticity and shock absorption performance, which can effectively buffer engine vibration. The internal porous structure of the foamed rubber sound insulation arc plate 2 can absorb and scatter sound waves, enhancing the sound insulation effect.

[0023] The number of conical sound insulation holes 3 is set to a certain extent. The conical sound insulation holes 3 are evenly distributed at equal intervals on the outer surface of the sound insulation arc plate 2. When noise propagates to the sound insulation arc plate 2, each conical sound insulation hole 3 works together to effectively attenuate sound waves of different frequencies and improve the sound insulation frequency range.

[0024] The anti-corrosion layer 4 is an epoxy resin anti-corrosion layer. The mounting base 5 is fixedly connected to the lower surface of the soft pad body 1. The epoxy resin anti-corrosion layer 4 is attached to the surface of the soft pad body 1, forming a solid protective barrier to isolate moisture, chemicals and other corrosive factors.

[0025] The mounting base 5 has a fixed connection to a positioning block 6. The surface of the positioning block 6 has a preset bolt groove 7. The positioning block 6 can accurately position the soft pad installation position to ensure installation accuracy, while the bolt groove 7 provides a firm connection.

[0026] There are four positioning blocks 6. The four positioning blocks 6 are fixedly connected to the four corners of the surface of the mounting base 5. During installation, the positioning blocks 6 at the four corners can evenly distribute the installation pressure, ensuring that the soft pad is installed in a balanced manner and avoiding insecure installation or damage due to uneven force.

[0027] The implementation principle of a car engine suspension damping pad in this embodiment is as follows: The pad body 1 serves as a damping component. Personnel first install the pad into a suitable position using the pre-set bolt grooves 7 on the surface of the positioning block 6. Sound-insulating arc plates 2 are fixedly connected to the outer surface of the pad body 1. These two sound-insulating arc plates 2 are located on both sides of the outer surface of the pad body 1, forming a double-sided sound insulation structure. This allows noise transmitted from different directions to be blocked and weakened by the sound-insulating arc plates 2 on both sides, thereby expanding the sound insulation coverage and effectively reducing noise transmission. The surface of the sound-insulating arc plates 2 is provided with conical sound-insulating holes 3. The diameter of the conical sound-insulating holes 3 decreases sequentially from the inside to the outside. When noise enters these conical holes, the sound waves are continuously reflected and interfered within the holes, and the energy is gradually consumed, further effectively reducing noise transmission. In addition, the outer surface of the pad body 1 is also provided with an anti-corrosion layer 4. This anti-corrosion layer 4 can resist the erosion of the pad body 1 by external corrosive substances, thereby extending its service life.

[0028] Furthermore, the soft pad body 1 is made of composite rubber material, which has good elasticity and shock absorption performance, and can effectively buffer engine vibration. The sound insulation arc plate 2 is made of foamed rubber material, and its internal porous structure can absorb and scatter sound waves, further enhancing the sound insulation effect. There are several conical sound insulation holes 3, and these conical sound insulation holes 3 are evenly distributed on the outer surface of the sound insulation arc plate 2. When noise propagates to the sound insulation arc plate 2, each conical sound insulation hole 3 works together to effectively attenuate sound waves of different frequencies, thereby improving the sound insulation frequency range.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
