Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a shock-absorbing structure for automotive cooling modules. Background Technology

[0002] In automobiles, especially heavy-duty vehicles, cooling modules (including radiators, condensers, etc.) are usually fixed to the chassis frame using mounting devices. This fixed installation method can easily cause the cooling module to resonate during vehicle vibrations, which can affect the cooling module. In order to minimize the impact of chassis vibrations on the cooling module, the mounting devices used usually have metal brackets with vibration damping pads or blocks to isolate the cooling module from the chassis frame, thereby reducing the impact caused by vibrations.

[0003] Currently, traditional automotive cooling module bracket vibration damping structures typically use aluminum alloy or steel metal brackets fixed to the vehicle body by bolts or welding. Independent rubber damping pads are installed between the cooling module and the metal bracket, absorbing vibration and impact through the elastic deformation of the rubber. However, the raw material cost of metal brackets is high, and their machining (such as stamping, bending, drilling) and welding processes are complex, requiring the assembly of multiple parts, making the process cumbersome, and prone to stress concentration due to installation errors. Utility Model Content

[0005] A vibration damping structure for an automotive cooling module, used for mounting a cooling module, includes: a plastic bracket body, an integrated damping pad, and a hot-melt column; the plastic bracket body is provided with mounting parts for connection with the vehicle body; the integrated damping pad is embedded in the plastic bracket body and is used to contact and support the cooling module; the hot-melt column is installed on the side of the plastic bracket body facing the cooling module, and the hot-melt column is used to be melted onto the surface of the integrated damping pad by hot riveting to form an integrated structure with the integrated damping pad.

[0006] Preferably, the plastic bracket body has an installation groove and a limiting groove inside, and the limiting groove is located at the end of the installation groove.

[0007] Preferably, the hot melt column is located between the mounting groove and the limiting groove.

[0008] Preferably, the plastic bracket body has a fixing groove inside, and the mounting component is disposed in the fixing groove.

[0009] Preferably, the mounting component includes a mounting block and a mounting screw, wherein the mounting block has a threaded groove adapted to the mounting screw.

[0010] Preferably, a first positioning hole is provided inside the plastic bracket body, and a rubber component is provided inside the first positioning hole.

[0011] Preferably, the integrated shock-absorbing pad has a second positioning hole inside, and a positioning plastic frame is provided inside the second positioning hole.

[0012] Preferably, the plastic support body has multiple perforated holes.

[0013] Preferably, the main body of the plastic bracket is injection molded from high-strength engineering plastic.

[0014] Preferably, the integrated shock-absorbing pad is made of rubber material.

[0015] The beneficial effects of this utility model are: This automotive cooling module vibration damping structure achieves mechanical interlocking between the integrated damping pad and the plastic bracket body through a hot-melt column riveting process. The three form an integrated structure, jointly undertaking the functions of installation, fixation, and vibration buffering of the cooling module. The process is simple and easy to install. By using a plastic bracket body instead of a metal frame, combined with the damping pad, a balance between lightweight and vibration damping performance is achieved. The integrated damping pad is embedded into the plastic bracket body through riveting, eliminating the failure risk of traditional adhesive or press-fitting processes. Utilizing the elastic modulus characteristics of the plastic bracket, combined with the damping performance of the damping pad, the vibration energy is absorbed by elastic deformation, while stress is dispersed. The combination of plastic and rubber forms acoustic impedance, effectively blocking the structural noise transmission path. Attached Figure Description

[0018] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0019] like Figure 1-4 As shown, this utility model proposes a vibration damping structure for an automotive cooling module, used to install a cooling module 4, comprising: a plastic bracket body 1, an integrated damping pad 2, and a hot-melt column 3; the plastic bracket body 1 is provided with mounting parts 5 for connecting to the vehicle body 14; the integrated damping pad 2 is embedded in the plastic bracket body 1 and is used to contact and support the cooling module 4; the hot-melt column 3 is installed on the side of the plastic bracket body 1 facing the cooling module 4, and the hot-melt column 3 is used to be melted onto the surface of the integrated damping pad 2 by hot riveting to form an integrated structure with the integrated damping pad 2.

[0020] In the technical solution of this utility model, a plastic bracket body 1 is used as the basic frame, and an integrated shock-absorbing pad 2 is integrated as a shock-absorbing component that directly contacts the cooling module 4. The integrated shock-absorbing pad 2 and the plastic bracket body 1 are mechanically interlocked through the hot riveting process of the hot melt column 3. The three form an integrated structure, which jointly undertakes the functions of installation, fixation and vibration buffering of the cooling module 4. The process is simple and easy to install. By using the plastic bracket body 1 to replace the metal frame and combining it with the shock-absorbing pad, a balance between lightweight and shock absorption performance is achieved. By embedding the integrated shock-absorbing pad 2 into the plastic bracket body 1 through riveting, the failure risk of traditional adhesive or press-fitting processes is eliminated. By utilizing the elastic modulus characteristics of the plastic bracket and the damping performance of the shock-absorbing pad, the vibration energy is absorbed by elastic deformation, while the stress is dispersed. The combination of plastic and rubber forms a sound impedance, effectively blocking the transmission path of structural noise.

[0021] The main body of the plastic bracket 1 is made of high-strength engineering plastic injection molding, and the integrated shock-absorbing pad 2 is made of rubber material.

[0022] like Figure 1 and Figure 2 As shown, the plastic bracket body 1 has an installation groove 6 and a limiting groove 7 inside, with the limiting groove 7 located at the end of the installation groove 6; the installation groove 6 and the limiting groove 7 can limit the integrated shock-absorbing pad 2, thereby enhancing the installation accuracy of the integrated shock-absorbing pad 2.

[0023] Specifically, the hot-melt column 3 is located between the mounting groove 6 and the limiting groove 7; by setting the hot-melt column 3 between the mounting groove 6 and the limiting groove 7, the hot-melt column 3 can serve as a guide column when the integrated shock-absorbing pad 2 is installed.

[0024] like Figure 1 and Figure 2 As shown, the plastic bracket body 1 has a fixing groove 8 inside, and the mounting component 5 is set in the fixing groove 8. The mounting component 5 includes a mounting block 51 and a mounting screw 52. The mounting block 51 has a threaded groove 53 that matches the mounting screw 52. The plastic bracket body 1 can be fixed to the vehicle body 14 by the mounting block 51 and the mounting screw 52.

[0025] like Figure 1 and Figure 2 As shown, the plastic bracket body 1 has a first positioning hole 9 inside, and a rubber component 10 is installed inside the first positioning hole 9. The integrated shock-absorbing pad 2 has a second positioning hole 11 inside, and a positioning plastic frame 12 is installed inside the second positioning hole 11. With the precise correspondence between the first positioning hole 9 and the second positioning hole 11, when installing the cooling module 4, the positioning component on the cooling module 4 can pass through the second positioning hole 11 and the first positioning hole 9, forming a positioning channel and preventing misalignment during installation. This dual positioning structure significantly improves the installation accuracy between the cooling module 4 and the bracket, ensuring that the cooling module is in the preset working position.

[0026] like Figure 1 and Figure 3 As shown, the plastic bracket body 1 has multiple hollow holes 13. The presence of multiple hollow holes 13 can significantly reduce the amount of material used in the plastic bracket body 1, thereby significantly reducing the overall weight of the bracket. For automobiles, especially heavy-duty vehicles, lightweighting of parts is an important way to reduce the energy consumption of the whole vehicle. The lighter bracket weight reduces the load during vehicle operation, so that the engine does not need to consume too much energy to drive the vehicle, which helps to reduce fuel consumption or electricity consumption, in line with the development trend of energy conservation and consumption reduction in the automotive industry.

[0027] Working principle: When the chassis vibrates during the car's operation, the vibration energy is transmitted through the car body to the plastic bracket body 1. The plastic bracket body 1 first absorbs some of the low-frequency vibration energy through its own elastic deformation. Meanwhile, the integrated damping pad 2, which is in contact with the cooling module 4, utilizes the high damping properties of rubber to provide secondary buffering for the mid-to-high frequency vibrations transmitted to the cooling module 4. The friction of the rubber molecular chains converts vibration energy into heat energy for dissipation, preventing resonance within the cooling module. The integrated damping pad 2 and the plastic bracket body 1 are mechanically interlocked through the hot-welding process of the hot-melt column 3, forming an integrated structure that jointly undertakes the functions of installation, fixation, and vibration buffering of the cooling module 4. The process is simple and easy to install. By using the plastic bracket body 1 instead of the metal frame and combining it with the damping pad, a balance between lightweight and vibration damping performance is achieved. By embedding the integrated damping pad 2 into the plastic bracket body 1 through riveting, the failure risk of traditional adhesive or press-fitting processes is eliminated. Through the elastic modulus characteristics of the plastic bracket, combined with the damping performance of the damping pad, the vibration energy is absorbed by elastic deformation, while stress is dispersed. The combination of plastic and rubber forms acoustic impedance, effectively blocking the transmission path of structural noise.

[0028] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
