Description

Technical Field

[0001] This utility model relates to the field of vehicle shock absorption pad technology, and in particular to a novel shock absorption pad for vehicle thermal management systems. Background Technology

[0002] Vibration damping pads are high-performance vibration damping components designed specifically for automotive thermal management systems. Through multi-layered structural innovation and the application of special materials, they achieve synergistic optimization of vibration absorption, thermal protection, and structural stability. They are suitable for connecting the thermal management modules of new energy vehicles and traditional fuel vehicles to the vehicle body frame.

[0003] However, existing traditional shock absorbers are mostly solid rubber or single foam structure, which can only absorb axial vibration and cannot take into account radial impact. Moreover, the rubber hardens and cracks at high temperatures, losing its elastic buffering ability. Therefore, a new type of shock absorber for vehicle thermal management systems is needed. Utility Model Content

[0004] The purpose of this invention is to provide a novel shock-absorbing pad for vehicle thermal management systems, which solves the problems of existing shock-absorbing pads being unable to absorb radial impacts and being prone to aging at high temperatures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel shock-absorbing pad for a vehicle thermal management system, comprising a rubber pad sleeve with an internal through hole, a shock-absorbing pad block for shock absorption docking at the top of the rubber pad sleeve, a docking groove for connecting the shock-absorbing pad blocks, an internal buffer reinforcement layer that fits against the inner wall of the rubber pad sleeve in the through hole of the rubber pad sleeve, and a buffer cavity that surrounds the rubber pad sleeve in the middle of the peripheral wall of the rubber pad sleeve.

[0006] Preferably, the internal buffer reinforcement layer includes a buffer sleeve and a shock-absorbing cavity, and the inner wall of the buffer sleeve has a shock-absorbing cavity extending along the axial direction.

[0007] Preferably, the damping cavities are equidistantly distributed on the inner wall of the buffer sleeve, and the cross-section of the damping cavities is semi-circular.

[0008] Preferably, the outer wall of the rubber gasket is provided with a heat-resistant protective layer, which is made of polyimide material.

[0009] Preferably, there are two sets of docking grooves and shock-absorbing pads, and the positions of the two sets of docking grooves and shock-absorbing pads are respectively distributed at the upper and lower ends of the rubber pad sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] An internal buffer reinforcement layer, fitted to the inner wall, is installed through the through-holes inside the rubber pad sleeve. This internal buffer reinforcement layer includes a buffer sleeve and shock-absorbing cavities with a semi-circular cross-section, evenly distributed on its inner wall. When subjected to vibration, the rubber pad sleeve first provides initial cushioning, while the internal buffer reinforcement layer further disperses and absorbs vibration energy, enhancing the overall shock absorption performance. The outer wall of the rubber pad sleeve is equipped with a heat-resistant protective layer made of polyimide. Polyimide has excellent heat resistance, which allows the shock-absorbing pad to operate normally in high-temperature environments. This effectively prevents the rubber pad sleeve from aging and deforming due to high temperatures, extends the service life of the shock-absorbing pad, and enhances its reliability in the vehicle thermal management system.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model relates to a novel shock-absorbing pad for an on-board thermal management system, such as... Figure 1-3As shown, the device includes a rubber sleeve 1 with internal holes. The upper and lower end faces of the rubber sleeve 1 have mating grooves 2 for connection with protrusions of a docking device. Shock-absorbing pads 5 are located on both sides of the mating grooves 2 on the upper and lower end faces of the rubber sleeve 1. The shock-absorbing pads 5 on the top of the rubber sleeve 1 serve a shock-absorbing docking function. The mating grooves 2 between the shock-absorbing pads 5 allow for connection with other components. Two sets of mating grooves 2 and shock-absorbing pads 5 are provided, distributed at the upper and lower ends of the rubber sleeve 1 respectively. This design allows for better docking with different components in the thermal management system, ensuring connection stability and compatibility, and enabling the shock-absorbing pads to function more effectively. The rubber pad 1 has an internal buffer reinforcement layer 3 inside the through hole. When subjected to vibration, the rubber pad 1 first plays a preliminary buffering role, and the internal buffer reinforcement layer 3 further disperses and absorbs vibration energy, enhancing the overall shock absorption performance. This ensures that the equipment passing through it is in close contact with the internal buffer reinforcement layer 3, reducing the pressure in the direction perpendicular to the equipment axis and playing a shock absorption role. The outer wall of the rubber pad 1 also has a buffer cavity 4, which extends along the peripheral wall of the rubber pad 1. This provides additional buffer space during the shock absorption process, further mitigating the impact of vibration, improving the shock absorption effect, reducing the pressure in the axial direction of the rubber pad 1, and providing a contraction function.

[0018] Among them, such as Figure 2 As shown, the internal buffer reinforcement layer 3 includes a buffer sleeve 301. The buffer sleeve 301 has a damping cavity 302 inside. The damping cavity 302 extends along the axis of the buffer sleeve 301 to provide damping between the radiator and the frame. The damping cavities 302 are equidistantly distributed on the inner wall of the buffer sleeve 301.

[0019] Among them, such as Figure 1 As shown, the outer wall of the rubber pad sleeve 1 is provided with a heat-resistant protective layer, which is made of polyimide material. Polyimide has good heat resistance, which enables the shock absorber to work normally in high temperature environment, effectively preventing the rubber pad sleeve 1 from aging and deforming due to high temperature, extending the service life of the shock absorber, and enhancing its reliability in the vehicle thermal management system.
