[0031] The thermal management integrated module of high-end new energy vehicles adopts a highly integrated "water tank" design. Through the high integration of components such as solenoid valves, electronic expansion valves, and heat exchangers onto the water tank, this integrated water tank better serves the vehicle's multi-functional needs, including air conditioning cooling, air conditioning cooling + battery + electric drive cooling, air conditioning heating, and air conditioning heating + battery pack heating. Compared to traditional thermal management systems, its structure is more complex, its weight is concentrated, and it also brings related noise problems. Therefore, the vibration isolation system design of the integrated water tank becomes particularly important, solving a key challenge in the path of innovative technologies for new energy vehicles.

[0032] To address the aforementioned problems, this invention proposes a vibration isolation structure for an integrated automotive water reservoir, aiming to provide a vibration isolation structure for an integrated automotive water reservoir that has a vibration isolation effect, reduces noise, and prevents vibration damage. Figures 1 to 4 This is a schematic diagram of one embodiment of the vibration isolation structure of an integrated water tank for automobiles provided by the present invention.

[0033] Please refer to Figures 1 to 3 This invention proposes a vibration isolation structure 1000 for an integrated water tank in an automobile, comprising a water tank body 1, a vibration isolation plate 2, and a vibration isolation sleeve 3; the vibration isolation plate 2 extends horizontally and covers the upper port of the water tank body 1; the vibration isolation sleeve 3 is sleeved around the periphery of the water tank body 1, wherein the contact surface between the vibration isolation sleeve 3 and the water tank body 1 adopts an interference fit.

[0034] In the technical solution of this invention, firstly, the vibration isolation plate 2 is covered at the upper port of the kettle body 1 to reduce the axial vibration of the kettle body 1; secondly, the vibration isolation sleeve 3 is sleeved on the periphery of the kettle body 1, and the contact surface between the vibration isolation sleeve 3 and the kettle body 1 adopts an interference fit. On the one hand, the interference fit ensures that the kettle body 1 will not fall off the vibration isolation plate 2 or the vibration isolation sleeve 3 due to vibration. On the other hand, it reduces the radial vibration of the kettle body 1, thereby ensuring the service life of the integrated kettle and avoiding damage from external forces.

[0035] Further, please refer to Figure 1 The upper inner wall of the vibration isolation sleeve 3 is provided with a first mating surface 31, and the contact surface between the first mating surface 31 and the water bottle body 1 adopts an interference fit. It can be understood that in some embodiments, because the assembly system needs to consider the transportation after assembly, the installation fit of the vibration isolation plate 2 and the vibration isolation sleeve 3 is designed as a clearance fit, which can achieve ideal radial vibration isolation. However, during the transportation of components, the water bottle body 1, the vibration isolation plate 2, and the vibration isolation sleeve 3 need to be integrated and loaded onto a vehicle for transportation. A clearance fit would cause the vibration isolation plate 2 to fall off from the assembly system, affecting logistics transportation and assembly with the vehicle in the workshop. Therefore, in another embodiment, the upper inner wall of the vibration isolation sleeve 3 is provided with the first mating surface 31, and the contact surface between the first mating surface 31 and the water bottle body 1 adopts an interference fit, thereby ensuring that the vibration isolation plate 2 will not fall off the water bottle body 1, thus ensuring the reliability of the integrated installation and the reliability of subsequent assembly with the vehicle.

[0036] Further, please refer to Figure 2The vibration isolation sleeve 3 has a second mating surface 32 on its lower inner wall. The contact surface between the second mating surface 32 and the water bottle body 1 is an interference fit. It is understood that, in order to reduce the impact of radial vibration on the water bottle body 1, the vibration isolation sleeve 3 has a first mating surface 31 on its upper inner wall. The contact surface between the first mating surface 31 and the water bottle body 1 is an interference fit. However, the water bottle body 1 is elongated. The further away from the first mating surface 31 a position is, the less restraint the first mating surface 31 exerts on radial vibration. That is, the further away from the first mating surface 31 a position is, the greater the radial vibration it experiences. This leads to high vibration noise in the assembly system, and components are easily damaged under the impact load of vibration. Therefore, the vibration isolation sleeve 3 has a second mating surface 32 on its lower inner wall. The contact surface between the second mating surface 32 and the water bottle body 1 is an interference fit, thus ensuring that the water bottle body 1 is not impacted by radial vibration in the assembly system, thereby ensuring the product's durability and the reliability of the vehicle assembled with the assembly system.

[0037] In addition, please refer to Figure 3 The vibration isolation sleeve 3 has at least one contact protrusion 33 protruding on the side facing the kettle body 1, and the contact protrusion 33 is in an interference fit with the outer wall of the kettle body 1. It is understood that, in order to reduce the impact wear or noise problems caused by radial vibration on the kettle body 1, in addition to the interference fit between the first mating surface 31 and the second mating surface 32 and the outer wall of the kettle body 1 as described above, in some embodiments, the vibration isolation sleeve 3 may also have at least one contact protrusion 33 protruding on the side facing the kettle body 1, and the contact protrusion 33 is in an interference fit with the outer wall of the kettle body 1, thereby reducing the radial vibration impact on the kettle body 1.

[0038] Furthermore, multiple contact protrusions 33 are provided, evenly distributed at intervals on the side of the vibration isolation sleeve 3 facing the kettle body 1. It can be understood that, in order to better reduce radial impact on the kettle body 1, multiple contact protrusions 33 are provided, evenly distributed at intervals on the side of the vibration isolation sleeve 3 facing the kettle body 1. This allows each contact protrusion 33 to share the radial vibration, thereby ensuring that the kettle body 1 is not damaged by radial load impact.

[0039] In addition, please refer to Figure 1The vibration isolation sleeve 3 is also provided with a hollow structure 34 to block the transmission of vibration. It can be understood that the vibrations experienced by the kettle body 1 come not only from the radial direction but also from the circumferential vibration impact. Therefore, the vibration isolation sleeve 3 is provided with the hollow structure 34 to reduce or block the transmission of circumferential vibration, thereby better protecting the kettle body 1 from damage due to vibration, and also having the effect of reducing noise.

[0040] Further, please refer to Figure 1 and Figure 4 The upper and lower end faces of the vibration isolation sleeve 3 are both recessed with a plurality of hollow grooves 341. The hollow grooves 341 extend along the length direction of the kettle body 1, and the plurality of hollow grooves 341 are evenly distributed at intervals on the upper and lower end faces of the vibration isolation sleeve 3; the hollow structure 34 includes the hollow grooves 341. It is understandable that vibration requires a medium to propagate. As the vibration propagates through the medium, the energy of the vibration decreases with distance, and the damage it can cause becomes limited. Based on this principle and idea, multiple hollow grooves 341 are recessed on the upper and lower end faces of the vibration isolation sleeve 3. The hollow grooves 341 extend along the length of the kettle body 1, and the multiple hollow grooves 341 are evenly distributed at intervals on the upper and lower end faces of the vibration isolation sleeve 3. Thus, when the kettle body 1 is subjected to circumferential vibration, the transmission of vibration encounters the hollow grooves 341. In order to achieve the transmission of vibration, the transmission path needs to be changed. As a result, the transmission distance of axial vibration is increased, and the energy of vibration is weakened by the increased distance, thereby protecting the kettle body 1 from vibration damage.

[0041] In addition, please refer to Figure 1 The lower end face of the vibration isolation sleeve 3 is provided with a first contact area 35, which is corrugated. It is understood that the water tank body 1 requires both static and dynamic vibration isolation. Therefore, the lower end face of the vibration isolation sleeve 3 is provided with the first contact area 35, which is corrugated. When the vehicle is static, the corrugated design of the first contact area 35 ensures that the vibration isolation sleeve and the vehicle body frame are in near-point contact, thereby providing good static vibration isolation.

[0042] Furthermore, the lower end face of the vibration isolation sleeve 3 is provided with a second contact area 36 opposite to the first contact area 35, and the second contact area 36 is spaced apart from the first contact area 35. It is understood that the water tank body 1 has both static and dynamic vibration isolation requirements. When the vehicle is in dynamic driving, if an axial impact occurs, and the axial impact exceeds a certain threshold, the second contact area 36 contacts the vehicle body bracket with a slight force, thereby relieving the force on the first contact area 35, thus reducing the axial impact and reducing the vibration of the integrated water tank transmitted to the entire vehicle.

[0043] Furthermore, the vibration damping plate 2 comprises a metallic material; and / or, the vibration damping sleeve 3 comprises a rubber material. It is understood that by designing the structure to isolate or reduce vibration, noise or damage caused by vibration can be reduced. Simultaneously, vibration can also be reduced by physically absorbing it. Therefore, the vibration damping plate 2 comprises a metallic material; and / or the vibration damping sleeve 3 comprises a rubber material. For axial vibration, the vibration damping plate 2 uses a metallic material, and for radial vibration, the vibration damping sleeve 3 uses a rubber material to absorb vibration, thereby reducing noise caused by vibration or damage to parts, and thus improving the vehicle's user experience.

[0044] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
