Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing pads for automobile thermal management systems, in particular to a suspension type shock-absorbing pad for the thermal management system. Background Art

[0002] The automotive integrated module assembly is an important component of the thermal management system of new energy vehicles. When the coolant passes through the integrated module assembly, it is transported to the corresponding module to be exchanged through the electronic water pump on the integrated module. High-frequency noise will be generated when the car is driving on the road or the electronic water pump is working. Traditional oil vehicles do not have integrated heat exchange modules. The corresponding pump bodies are all supported by rubber and independently connected to the body. In addition, due to the large vibration and noise of the engine itself, the vibration and noise of the corresponding pump body can be ignored. Therefore, there were no relevant performance requirements for fuel vehicles in the past. With the development of new energy technology and the improvement of the requirements for the thermal management system of the whole vehicle, the new energy thermal management system is now basically integrated into an integral module, and the connection between the integral module and the body, as well as the overall vibration and noise reduction function indicators, are also generated. Since new energy vehicles do not have the vibration of traditional fuel vehicle engines, and the motor itself is quiet, as people's requirements for the riding experience increase, the vibration and noise transmitted by the integrated module are particularly prominent for drivers and passengers, so the new energy vehicle market has an increasing demand for high-performance integrated module shock pads.

[0003] As the main shock-absorbing and noise-reducing component of the thermal management system of new energy vehicles, the integrated module shock-absorbing pad mainly buffers the vibration of the integrated module shock-absorbing pad itself and reduces the vibration caused by road bumps and undulations transmitted to the integrated module, and protects the integrated module from instantaneous large impacts caused by driving on harsh roads or deep potholes or raised roads. Both its own vibration and the vibration transmitted from the road surface will cause irreversible damage to the integrated module and cause a certain degree of noise. Therefore, the reliability of the integrated module shock-absorbing pad is very important. Utility Model Content

DETAILED DESCRIPTION

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar symbols throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] like Figure 1-2 As shown, the utility model discloses a suspension type vibration damping pad for a thermal management system, comprising:

[0035] The support bracket assembly 100 and the shock-absorbing rubber body 200 are vulcanized and formed with the support bracket assembly 100 by an integral vulcanization method. Figure 3 As shown, the assembly section 210 of the rubber body 200 is substantially I-shaped, forming two assembly grooves 220 , and the shock-absorbing pad is assembled with the vehicle body component A through the two assembly grooves 220 .

[0036] The support bracket assembly 100 may be made of metal, or according to the use requirements, may be made of a material formed by PA66 with a certain amount of glass fiber, or may be made of 6061-T6 aluminum or other materials.

[0037] like Figure 4 As shown, the support bracket assembly 100 includes two limiting fixing pads 110 and a fixing bushing 120. The two ends of the fixing bushing 120 are respectively fixedly connected to a limiting fixing pad 110. The fixing bushing 120 and the limiting fixing pads 110 at both ends can be fixed by first pressing and riveting and then welding. Ensure that the support bracket assembly 100 has sufficient strength.

[0038] The two fixing gaskets 110 can adopt a structure parallel to each other as shown in the figure, and can be installed at a certain angle to each other, and can be adjusted according to usage requirements to meet actual usage conditions.

[0039] The appearance of the support bracket assembly 100 is not limited to the regular rectangular shape shown in the figure, and can be presented in square, circular, elliptical and other special structural forms according to the structural form of the vehicle body and the counterpart.

[0040] Further, such as Figure 4As shown, an internally threaded bushing 130 is embedded in the fixed bushing 120 , and inclined surfaces 131 are provided at both ends of the internally threaded bushing 130 . The large-angle inclined surfaces 131 facilitate bolt positioning during blind installation, thereby effectively improving assembly efficiency.

[0041] During assembly, the support bracket assembly 100 is integrally hung on a vehicle body member (not shown) by bolting the internal threaded bushing 130 .

[0042] Further, such as Figure 4 As shown, the fixed gasket 110 is provided with a limiting hole 111. When the support bracket assembly 100 and the shock-absorbing rubber body 200 are vulcanized, the rubber body 200 fills the limiting hole 111, which can limit the displacement and sliding of the support bracket assembly 100 and the rubber body 200 to maintain a stable connection between them.

[0043] Further, such as Figure 5 , 9 As shown, the rubber body 200 includes two shock absorbing layers 230 and an assembly layer 240 , which are vulcanized and integrally formed. The assembly layer 240 is located between the two shock absorbing layers 230 , and the shock absorbing layer 230 is provided with a variety of buffer structure holes 250 .

[0044] A mesh-like inclined support foot structure is formed between the various buffer structure holes 250, which can effectively absorb the vibration force in the main vibration direction through the mesh-like inclined support foot structure, and effectively decompose and absorb its force through the mesh-like inclined support foot angles, thereby facilitating shock absorption and noise reduction.

[0045] like Figure 6 As shown, a buffer structure hole 250 is provided with a trapezoidal stopper 251, and the buffer structure hole 250 is roughly in an eight-shaped shape, and the buffer structure hole 250 forms a buffer angle 1 252. The buffer angle 1 252 of the eight-shaped buffer structure hole 250 presents a certain angle θ1, Figure 6 The buffer angle 252 shown is approximately 60°, and this angle can be adjusted according to actual shock absorption performance requirements, and the adjustment range can be adjusted from 30° to 90°.

[0046] like Figure 7 As shown, a buffer structure hole 250 is triangular, and the buffer structure hole 250 forms a buffer angle 253. The buffer angle 253 of the triangular buffer structure has a certain angle θ2, Figure 7 The buffer angle 253 shown is approximately 60°, and this angle can also be adjusted according to actual shock absorption performance requirements, and the adjustment range can be adjusted from 30° to 90°.

[0047] By using the buffer angle 1 252 and the buffer angle 253 in combination, the shock-absorbing pad can buffer small vibrations and limit small displacement vibrations, which is beneficial for the noise reduction of the first-level shock-absorbing pad and improves the stability of use.

[0048] Further, such as Figure 6 As shown, the interior of the eight-shaped buffer structure hole 250 has a trapezoidal stopper 251, and the stopper of the trapezoidal protrusion structure and the structure hole wall have a certain shock-absorbing gap 254. The shock-absorbing gap 254 is a spacing that allows initial shock absorption. After the shock-absorbing gap 254 is compressed, the structure hole wall contacts the trapezoidal stopper 251 to limit the larger displacement vibration. The trapezoidal stopper 251 can effectively buffer the impact of a large external force to form an impact limit.

[0049] Further, such as Figure 8 As shown, the cross section 241 of the assembly layer is corrugated. The corrugated structure of the assembly layer 240 can adjust the corrugation spacing according to the product stiffness performance index, and the assembly layer 240 can also adjust the corrugation height according to the limit requirements of the two shock-absorbing layers 230.

[0050] Further, such as Fig.10 As shown, a semi-U-shaped groove 260 structure is provided at the connection between the corrugated structure assembly layer 240 and the two shock-absorbing layers 230 to form a groove gap. By setting the groove gap, the compressive stress value and the compressive strain amount of the corrugated part of the assembly layer 240 can be controlled, and the stiffness index and durability performance in this direction can be controlled.

[0051] In the support bracket assembly 100 of the present invention, the fixed gasket 110 and the fixed bushing 120 are welded after being pressed together, which can ensure the installation and assembly force and the anti-slip force. The fixed bushing 120 is embedded with an internal threaded bushing 130 to facilitate the overall assembly and tightening.

[0052] The shock-absorbing rubber body 200 is provided with a variety of buffer structure holes 250, rubber mesh inclined feet and trapezoidal limiting structures, which can effectively absorb the vibration force in the main vibration direction through the mesh inclined foot structure, and can effectively decompose and absorb the vibration force through the mesh inclined foot angle, which is convenient for shock absorption and noise reduction, and improves the NVH effect of the vehicle. Setting a reasonable buffer angle can effectively decompose the force and greatly reduce the strain of the rubber itself. Combined with the trapezoidal limiting block 251 inside the structural hole, a buffer boss is formed, which effectively improves the durability of the rubber body 200.
