Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to an expansion tank and a vehicle. Background Technology

[0002] Expansion tanks are widely used in the cooling systems of automobiles and other vehicles to store and compensate for volume changes caused by the thermal expansion of coolant, serving as an important component of the coolant circulation loop. Existing expansion tanks are typically directly connected to the vehicle body structure via fasteners for rigid support. However, during vehicle operation, especially under conditions such as bumpy roads, high-speed cornering, and off-road driving, the vehicle body generates vibrations of varying frequencies and amplitudes. These vibrations are directly transmitted to the expansion tank connected to the body, causing abnormal noises and damage. Summary of the Invention

[0003] In order to solve the above-mentioned problems in the prior art, this utility model provides an expansion pot.

[0004] The first aspect of this application provides an expansion pot, comprising: a pot body and an elastic shock absorber; The tank body has a dual chamber for holding coolant. Each chamber is provided with an inlet, an outlet, and a filling port. At least one fastener for connecting to the vehicle body structure is provided on the outer periphery of the tank body. The elastic shock absorber is installed at the bottom of the kettle body.

[0005] This technical solution provides an expansion container with two chambers. The dual-chamber design achieves independent circuit isolation, reducing the risk of cross-contamination. Simultaneously, elastic shock absorbers absorb vibration energy from the bottom, isolating it from transmission to the connection point and preventing loosening that could induce collision noise. The fixing components mechanically secure the container to the vehicle body, providing rigid support and reducing abnormal noises through shock absorption. In practical applications, this enhances stability on bumpy roads and improves the driving experience.

[0006] In one embodiment, the elastic damping member includes an integrally formed elastic damping disc and a mounting portion; The mounting part is installed at the bottom of the kettle body; The elastic damping disc is disposed between the kettle body and the vehicle body structure to provide cushioning.

[0007] In this technical solution, the mounting part is fixed to the bottom of the kettle body by snaps or embedding to ensure a stable connection; the elastic damping disc acts as a buffer layer, undergoing elastic deformation when vibration is transmitted, absorbing and dissipating kinetic energy, effectively isolating the kettle body from the vehicle body, and avoiding collision noise at the connection point. The one-piece molded structure avoids stress concentration at the joints and improves fatigue resistance.

[0008] In one embodiment, the bottom of the kettle body is provided with a connecting part, the connecting part including a protrusion, and the protrusion is provided with a mounting groove; The elastic damping element has a mounting portion that matches the mounting groove.

[0009] In this technical solution, the protrusion provides positioning, and the mounting groove and the elastic damping component mounting part complement each other and fit together. Through friction and geometric tolerance, a gapless connection is achieved to prevent lateral sliding or collision noise under vibration.

[0010] In one embodiment, the mounting groove is an annular groove; The mounting portion is an annular protrusion that mates with the mounting groove; When the elastic shock absorber is installed on the kettle body, the annular protrusion is embedded in the annular groove.

[0011] In this technical solution, the annular groove provides a continuous circumferential structure, and the protrusions, once embedded, form a sealed connection, dispersing radial / axial forces under vibration (similar to the principle of a bearing ring) and preventing collision noise caused by local loosening. From a dynamic perspective, the symmetrical design absorbs multi-directional impacts and optimizes stress distribution.

[0012] In one embodiment, the elastic damping disc has a plurality of concentrically arranged damping protrusions on the side away from the kettle body.

[0013] In this technical solution, the concentric convex ring contacts the vehicle body. The outer layer first deforms to absorb low-frequency vibrations, while the inner layer responds to high frequencies, achieving graded buffering and effectively suppressing vibration-induced noise.

[0014] In one embodiment, the fastener includes a fixing plate fixed to the outer periphery of the pot body, the fixing plate having fixing holes for fasteners to pass through.

[0015] In this technical solution, the fixing plate is integrally fixed to the outer periphery, and the holes allow fasteners to pass through, forming a rigid node with the vehicle body. It transmits load but isolates vibration peaks through shock absorption, avoiding collision noise at the connection point. From a static perspective, stability is ensured by using shear / tensile force balance.

[0016] In one embodiment, two reinforcing plates are provided between the fixing plate and the outer periphery of the pot body. The two reinforcing plates are arranged in parallel on the fixing plate, and the fixing hole is located between the two reinforcing plates.

[0017] In this technical solution, parallel reinforcing plates form a supporting structure to enhance bending stiffness, and fixing holes are placed in the gaps to avoid interference.

[0018] In one embodiment, the expansion vessel further includes at least one limiting member; The limiting component includes a limiting plate, which is connected to the outer periphery of the kettle body, and the limiting plate is provided with a limiting hole.

[0019] In this technical solution, the structural components on the vehicle body extend into the limiting holes on the limiting plate to restrict the multi-degree-of-freedom movement of the kettle body and prevent loosening, collisions, and noise.

[0020] In one embodiment, the limiting plate is surrounded by a surrounding plate to form a limiting channel connecting the limiting hole, and a support plate is provided between the surrounding plate and the kettle body.

[0021] In this technical solution, the enclosure forms a limiting channel that connects to the limiting hole. The limiting channel increases the contact surface with the vehicle body structural components, improving the torsional resistance of the limiting components. The support plate bridges and enhances torque resistance, preventing deformation and noise under vibration.

[0022] The second aspect of this application provides a vehicle that includes an expansion tank as provided in the first aspect.

[0023] In this technical solution, the expansion tank compensates for coolant expansion, the shock absorber isolates vibration, and ensures engine / battery stability; the fixing / limiting components are integrated with the vehicle body to provide system buffer and avoid connection noise.

[0024] The advantages of this utility model over the prior art are as follows: The elastic damping component absorbs vibration energy during vehicle operation through bottom mounting, preventing loosening and subsequent collision noise. The fixing component mechanically secures the expansion tank to the vehicle body, providing rigid support and reducing abnormal noises through shock absorption. In practical applications, it enhances stability on bumpy roads, prevents damage to the expansion tank, reduces after-sales costs, and also prevents abnormal noises from the expansion tank, thus improving the driving experience.

[0039] Example 1 like Figure 1 and Figure 2 As shown, this application provides an expansion tank, including a tank body 1 and an elastic damping member 4. The tank body 1 has a dual-chamber structure for holding coolant, each chamber having an inlet 12, an outlet 14, and a filling port 11. At least one fixing member 2 for connecting to the vehicle body structure is provided on the outer periphery of the tank body 1. The elastic damping member 4 is installed at the bottom of the tank body 1. It should be noted that... Figure 1 A sealing cap is installed on the liquid filling port 11.

[0040] In actual use, the dual chambers are connected to the vehicle's cooling system via the inlet 12 and outlet 14. When the coolant expands due to heat, it enters the chambers to maintain stable system pressure and prevent pipe rupture or leakage. The filler port 11 is used to replenish coolant and ensure a balanced liquid level. The elastic damping component 4 absorbs vibration energy during vehicle operation through bottom mounting, preventing loosening that could induce collision noise. The fixing component 2 mechanically secures the reservoir to the vehicle body, providing rigid support and reducing abnormal noises through shock absorption. In practical applications, this enhances stability on bumpy roads and improves the driving experience.

[0041] like Figure 2 and Figure 3As shown, in a specific example provided in this application, the elastic damping component 4 includes an integrally formed elastic damping disc 41 and a mounting portion 42; the mounting portion 42 is mounted on the bottom of the kettle body 1; the elastic damping disc 41 is disposed between the kettle body 1 and the vehicle body structure to provide cushioning. It should be noted that in this embodiment, the elastic damping component 4 is made of silicone material.

[0042] Understandably, the mounting part 42 is fixed to the bottom of the kettle body 1 by snap-fit ​​or embedding to ensure a stable connection; the elastic damping disc 41 acts as a buffer layer, undergoing elastic deformation when vibration is transmitted, absorbing and dissipating kinetic energy, effectively isolating the impact between the kettle body and the vehicle body, and avoiding collision noise at the connection point. The one-piece molded structure avoids stress concentration at the joints and improves fatigue resistance.

[0043] like Figure 2 and Figure 3 As shown, in a specific example provided in this application, the bottom of the kettle body 1 is provided with a connecting part, the connecting part includes a protrusion 141, and the protrusion 141 is provided with a mounting groove 142; the elastic shock absorber 4 has a mounting part 42 that matches the mounting groove 142.

[0044] Understandably, the protrusion 141 provides positioning, and the mounting groove 142 complements and fits into the damping mounting part 42, achieving a gapless connection through friction and geometric tolerances to prevent lateral sliding or collision noise under vibration.

[0045] like Figure 2 and Figure 3 As shown, in a specific example provided in this application, the mounting groove 142 is an annular groove; the mounting part 42 is an annular protrusion 141 that cooperates with the mounting groove 142; when the elastic damping member 4 is installed on the kettle body 1, the annular protrusion 141 is embedded in the annular groove.

[0046] Understandably, the annular groove provides a continuous circumferential structure, and the protrusion 141, once embedded, forms a sealed connection, dispersing radial / axial forces under vibration and preventing localized loosening that could lead to collision noise. From a dynamic perspective, the symmetrical design absorbs impacts from multiple directions and optimizes stress distribution.

[0047] like Figure 3 As shown in the specific example provided in this application, the elastic damping disc 41 has several concentrically arranged damping convex rings 43 on the side away from the body 1. The concentric convex rings contact the vehicle body, and the outer layer first deforms to absorb low-frequency vibrations, while the inner layer responds to high frequencies, achieving graded buffering and effectively suppressing vibration-induced noise.

[0048] like Figure 2 As shown, in a specific example provided in this application, the fastener 2 includes a fixing plate 21 fixed to the outer periphery of the kettle body 1, and the fixing plate 21 is provided with fixing holes 22 for fasteners to pass through.

[0049] It can be understood that the fixing plate 21 is integrally fixed to the outer periphery, and the holes allow fasteners to pass through, forming a rigid node with the vehicle body. It transmits load but isolates vibration peaks through shock absorption, avoiding collision noise at the connection point; from a static perspective, it utilizes shear / tensile force balance to ensure stability. In this embodiment, bolts are used as fasteners.

[0050] like Figure 2 As shown, in a specific example provided in this application, two reinforcing plates 23 are provided between the fixing plate 21 and the outer periphery of the pot body 1. The two reinforcing plates 23 are arranged in parallel on the fixing plate 21, and the fixing hole 22 is located between the two reinforcing plates 23.

[0051] Understandably, the parallel reinforcing plate 23 forms a supporting structure to enhance bending stiffness, and the fixing hole 22 is placed in the gap to avoid interference.

[0052] like Figure 3 and Figure 4 As shown, in a specific example provided in this application, the expansion pot also includes at least one limiting member 3; the limiting member 3 includes a limiting plate 31, which is connected to the outer periphery of the pot body 1, and the limiting plate 31 is provided with a limiting hole 32.

[0053] Understandably, structural components on the vehicle body extend into the limiting holes 32 on the limiting plate 31 to restrict the multi-degree-of-freedom movement of the pot body 1, preventing loosening, collisions, and noise. Specifically, in this embodiment, the limiting hole is a strip-shaped hole, which increases the area of ​​the vehicle body structural components extending into the limiting hole, improves the torsional resistance of the limiting plate, and increases the stability of the expansion pot.

[0054] like Figure 3 and Figure 4 As shown, in a specific example provided in this application, the limiting plate 31 is surrounded by a surrounding plate 33 to form a limiting channel connecting the limiting hole 32, and a support plate 34 is provided between the surrounding plate 33 and the pot body 1. It should be noted that in this embodiment, the support plate 34 has crisscrossing reinforcing ribs 35 to improve the strength of the support plate 34 and the limiting plate 31.

[0055] Understandably, the enclosure 33 forms a limiting channel that connects to the limiting hole 32. The limiting channel increases the contact surface with the vehicle body structural components, improving the torsional resistance of the limiting components. The support plate 34 bridges and enhances torque resistance, preventing deformation and noise under vibration.

[0056] Example 2 This embodiment provides a vehicle including the expansion tank from Embodiment 1. By integrating the expansion tank into the cooling system, this vehicle achieves overall thermal management and vibration control, improving fuel efficiency, safety, and comfort. It is suitable for electric vehicles (EVs), traditional gasoline vehicles, or off-road vehicles. The vehicle's working principle integrates the expansion tank into the cooling system: during coolant circulation, the dual-chamber design compensates for thermal expansion, maintaining pressure balance; when vibrations (such as road swaying) are transmitted, the elastic damping element 4 absorbs energy, and the fixing element 2 and limiting element 3 constrain displacement, preventing collision noise at the connection points; the damping mechanism of the shock-absorbing disc and the stiffness of the reinforcing plate 23 are used for reinforcement. The limiting channel guides the alignment of fasteners, ensuring installation accuracy; the overall mechanism isolates noise transmission in bumpy environments, improving NVH performance.

[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
