Description

Technical Field

[0001] This application relates to the field of vibration reduction technology, and in particular to a vibration absorber mounting structure and vehicle. Background Technology

[0002] To address vibration issues arising from excitation energy in various vehicle systems such as the powertrain, transmission, and tires, installing vibration absorbers on vibration-bearing structures like the subframe, suspension system, engine / transmission mounts, transmission system, and / or body has become a crucial technical approach for automakers. A vibration absorber, as a device used to attenuate the vibration energy of a mechanical system, typically consists of damping components and connecting structures. Its core function is to reduce the vibration response of the vibration-bearing structure under excitation by coupling energy with the structure itself through its vibrational characteristics.

[0003] The mounting structure of the vibration absorber is a crucial part connecting the absorber to the vibrating load-bearing structure. Its main function is to provide stable support for the absorber, ensuring a reliable connection between the absorber and the load-bearing structure, so that vibration energy can be effectively transferred to and attenuated by the absorber. In practice, the absorber must form an integral unit with the load-bearing structure to effectively attenuate the transmitted vibration energy. This places high demands on the strength of the mounting structure; only a high-strength mounting structure can guarantee that the two form a stable whole, thereby achieving effective attenuation of vibration energy.

[0004] However, there is a technical contradiction in the existing vibration absorber installation structure: on the one hand, in order to ensure the vibration reduction effect of the vibration absorber, the installation structure needs to have sufficient strength to ensure that the vibration absorber and the vibration bearing structure form an integral whole, but directly strengthening the installation structure will lead to an increase in overall weight and cost; on the other hand, if the strength of the installation structure is insufficient, it is difficult to ensure a reliable connection between the vibration absorber and the vibration bearing structure, thereby weakening the vibration reduction efficiency of the vibration absorber, failing to effectively attenuate system vibration, and ultimately having an adverse impact on the normal operation and user experience of the equipment. Utility Model Content

[0005] This application provides a vibration absorber mounting structure and a vehicle, the purpose of which is to effectively reduce the weight and cost of the mounting structure while ensuring the vibration reduction effect of the vibration absorber by adding reinforcing plates and related structures, thereby improving the practical performance of the vibration absorber and the overall quality of the vehicle.

[0006] To achieve the above objectives, this application adopts the following technical solution: This application provides a vibration absorber mounting structure for fixing the vibration absorber to the vibration bearing structure; a reinforcing plate is provided between the vibration absorber and the vibration bearing structure, and the vibration absorber, the reinforcing plate and the vibration bearing structure are tightly fitted and rigidly connected; The vibration absorber includes a base plate and a circular ring plate. The base plate is located on the side of the vibration absorber facing the vibration bearing structure. The circular ring plate is located between the base plate and the vibration bearing structure. The base plate and the circular ring plate are connected by an arc-shaped transition. The circular ring plate, the arc-shaped transition, and the base plate are integrally formed. The reinforcing sheet is attached to the base plate on the side facing the vibration absorber.

[0007] In the above embodiments, the damping plate of the vibration absorber facing the vibrating load-bearing structure is integrally formed from a circular ring plate, an arc-shaped transition section, and a base plate, with an arched cross-section. This design disperses vibration stress through the mechanical properties of the arc-shaped transition section, avoiding stress concentration at the installation point. This enhances the deformation resistance of the damping plate and reduces redundant material. Simultaneously, the reinforcing plate precisely fits the base plate, specifically reinforcing the connection area between the vibration absorber and the vibrating load-bearing structure in a small area, compensating for the overall strength deficiency of the damping plate and reducing local stress burden. The two complement each other through their mechanical properties, forming a synergistic effect: the arc-shaped transition section disperses stress to reduce the load-bearing pressure of the reinforcing plate, while the reinforcing plate strengthens the overall strength of key connection points, jointly resisting vibration impact and preventing fatigue damage in the installation area. In addition, the damping plate replaces material thickening with shape optimization, and the reinforcing plate avoids large-area reinforcement with precise strengthening. The two work together to significantly reduce the amount of material used while ensuring the connection strength between the vibration absorber and the vibration bearing structure (that is, ensuring that the vibration absorber and the vibration-absorbing system form a rigid whole and improve the vibration absorption effect). This achieves a lightweight design of the installation structure, effectively controls weight and manufacturing costs, and ultimately solves the balance problem between high strength requirements and weight and cost pressures.

[0008] In some embodiments of this application, the vibration bearing structure is provided with an installation area, and the vibration absorber is connected to the installation area; the ratio of the thickness of the reinforcing sheet to the thickness of the installation area is greater than or equal to 1 and less than or equal to 2.

[0009] In the above embodiments, this application achieves scientific reinforcement of the installation structure by limiting the ratio of the thickness of the reinforcing sheet to the thickness of the installation area of ​​the vibration-bearing structure: if the ratio is too low, the reinforcement effect is not obvious and the connection strength cannot be guaranteed; if the ratio is too high, the weight will increase significantly and the reinforcement effect will decrease marginally. This range ensures that the strength of the installation structure meets the standards while controlling the overall weight to the maximum extent, balancing the strength requirements and the pressure of weight and cost.

[0010] In some embodiments of this application, the reinforcing sheet is a cylindrical structure with a diameter of 30-34 mm and a thickness of 1.5-2.5 mm.

[0011] In the above embodiments, this application specifies that the diameter of the reinforcing sheet is 30~34 mm and the thickness is 1.5~2.5 mm, which increases the force-bearing area between the vibration absorber and the vibration bearing structure, improves the connection stability, and avoids the increase in weight and cost caused by excessive size.

[0012] In some embodiments of this application, the diameter of the base plate is 33-37 mm.

[0013] In the above embodiments, the diameter of the base plate is limited to 33~37 mm, which is slightly larger than the diameter of the reinforcing sheet (30~34 mm), so that the reinforcing sheet can always be completely placed inside the base plate, ensuring that the two fit together fully and improving stress transfer efficiency.

[0014] In some embodiments of this application, the vertical distance between the base plate and the annular plate is 1.5~2.5 mm; the thickness of the reinforcing sheet is greater than or equal to the vertical distance between the base plate and the annular plate.

[0015] In the above embodiments, this application also limits the vertical distance between the base plate and the annular plate to the range of 1.5 mm to 2.5 mm, and the thickness of the reinforcing sheet is always greater than or equal to the vertical distance between the base plate and the annular plate, so that the reinforcing sheet can always be fully embedded in the recess formed by the base plate and the arc transition and fit against the base plate within the range, eliminating assembly gaps.

[0016] In some embodiments of this application, the vibration absorber, the reinforcing sheet, and the vibration bearing structure are closely fitted together and rigidly connected by a connecting assembly; wherein, the connecting assembly includes: The mounting rod passes through the vibration absorber, the reinforcing plate, and the vibration bearing structure; Fasteners, which are fixed to the mounting rod, are located on the side of the vibration bearing structure opposite to the reinforcing plate.

[0017] In the above embodiments, the vibration absorber, reinforcing plate, and vibration bearing structure are connected by a connecting assembly consisting of a mounting rod and fasteners. The fasteners are located on the side of the vibration bearing structure opposite to the reinforcing plate. The mounting rod passes through the vibration absorber, reinforcing plate, and vibration bearing structure, and then engages with and secures the fasteners, ensuring the integrity and stability of the connection. This structural design avoids vibration energy transmission loss due to loose connections, ensuring the vibration absorber effectively attenuates system vibrations. It also simplifies the assembly process and improves installation reliability. Furthermore, the tight fit emphasizes the need for the fasteners to apply pre-clamping force to the vibration absorber, reinforcing plate, and vibration bearing structure, ensuring a tight overall structure and improving vibration transmission efficiency.

[0018] In some embodiments of this application, the reinforcing sheet and the fastener are respectively welded and fixed to the vibration bearing structure; The fastener has at least one first weld bead along its circumference on its outer edge, and the reinforcing sheet has at least one second weld bead along its circumference on its outer edge.

[0019] In the above embodiments, the reinforcing plate and fastener of this application are respectively welded to both sides of the vibration bearing structure through at least one weld pass (second weld pass, first weld pass). The rigid fixation formed by welding can prevent the fastener from loosening and avoid relative rotation between the reinforcing plate and the vibration absorber. On the basis of strengthening the connection stability, it further ensures the efficient transmission of vibration energy and ensures that the vibration reduction performance of the vibration absorber is fully utilized.

[0020] In some embodiments of this application, on any projection plane perpendicular to the axis of the mounting rod, the first weld bead and the second weld bead are offset from each other in the circumferential direction.

[0021] In the above embodiments, although both the first and second welds are segmented structures, the overall coverage of multiple first and second welds, arranged in a staggered circumferential manner, can maximize the coverage of the entire circumference of the fastener and reinforcing plate, effectively creating a near-perfect weld fixing effect in the circumferential direction. This layout design, through a vibration-bearing structure, enables the welds on both sides to complement each other in terms of force. Without increasing the total weld length (i.e., reducing material consumption and overall weight), it effectively improves the connection stiffness and fatigue life, achieving a balance between "shortest weld length and highest welding strength," thus balancing the strength requirements of the installation structure with the goal of lightweighting. At the same time, the staggered circumferential arrangement minimizes the overlap of the heat-affected zones of the welds on both sides, reduces the concentration of residual welding stress, and further ensures the structural stability of the connection.

[0022] In some embodiments of this application, on any projection plane perpendicular to the axis of the mounting rod, the sector area corresponding to the first weld bead and the sector area corresponding to the second weld bead do not overlap, and the first weld bead and the second weld bead together cover a 360° circumference.

[0023] In the above embodiments, on the one hand, material waste and weight redundancy caused by excessively long weld beads can be prevented; on the other hand, it can be ensured that the overall coverage of all the first weld beads and all the second weld beads can completely cover the entire circumference of the fastener and reinforcing plate, which is equivalent to forming a welded fixing effect without dead angles in the circumferential direction. This design not only improves the structural strength, but also makes the stress on the installation structure evenly distributed in the circumferential direction, further enhancing the overall stress balance, reducing the risk of local stress concentration, and thus significantly improving the reliability and fatigue resistance of the connection structure.

[0024] In addition, this application also provides a vehicle, including a vehicle body, wherein a vibration bearing structure and a vibration absorber are provided in the vehicle body, and the vibration absorber is fixed to the vibration bearing structure through a vibration absorber mounting structure.

[0025] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0032] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] When a vehicle is running, the excitation energy generated by components such as the powertrain, transmission system, and tires will cause vibrations in the subframe, suspension, engine mounts, and body, which are load-bearing structures. To mitigate this problem, automakers generally adopt the solution of installing vibration absorbers on the load-bearing structures. Vibration absorbers reduce the vibration response of the load-bearing structures by using the synergistic effect of damping components and connecting structures, and by leveraging their own vibration characteristics to form an energy coupling with the load-bearing structure.

[0034] The connection between the vibration absorber and the vibration-bearing structure depends on the mounting structure. The core function of the mounting structure is to provide stable support: only when the mounting structure is sufficiently reliable can it ensure that the two form a rigid whole, allowing vibration energy to be smoothly transferred to the vibration absorber and effectively attenuated. This means that the strength of the mounting structure directly determines the working efficiency of the vibration absorber.

[0035] However, in the existing technology, there are irreconcilable technical contradictions in the installation structure of the vibration absorber: The root of the problem lies in the conflict between the demands for strength, lightweighting, and cost: if high strength is pursued to ensure the integrity of the vibration absorber and the load-bearing structure (and thus ensure the vibration reduction effect), it is often necessary to strengthen the installation structure by thickening the materials and adding reinforced components, which will directly lead to an increase in weight and manufacturing costs; conversely, if the installation structure is weakened in order to control weight and cost, the connection between the two will become loose due to insufficient strength or loosen and be damaged after long-term use, and they will not be able to form an effective whole, resulting in obstruction of vibration energy transmission, a significant decrease in the vibration reduction efficiency of the vibration absorber, and ultimately the vehicle vibration problem will not be solved, affecting driving stability and ride experience.

[0036] Based on this, this application proposes a vibration absorber mounting structure and vehicle. By setting a reinforcing plate 300 between the vibration absorber 200 and the vibration bearing structure 100, and using the annular plate 210, arc transition 211 and base plate 212 to cooperate with the reinforcing plate 300 to disperse stress, and by adopting the staggered arrangement of the first weld 231 and the second weld 310 to cover more of the circumference, the design achieves the effect of improving the strength of the mounting structure to ensure a stable connection between the vibration absorber 200 and the vibration bearing structure 100, while reducing redundant materials and weld length through structural optimization, thereby reducing weight and cost. This solves the technical contradiction in the prior art where the vibration absorber 200 mounting structure is difficult to balance strength, lightweight and cost.

[0037] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0038] As attached Figures 1 to 11 As shown in an illustrative embodiment of this application, the vibration absorber mounting structure is used to fix the vibration absorber 200 onto the vibration bearing structure 100; a reinforcing plate 300 is provided between the vibration absorber 200 and the vibration bearing structure 100, and the vibration absorber 200, the reinforcing plate 300 and the vibration bearing structure 100 are rigidly connected.

[0039] In some embodiments, the vibration absorber 200, the reinforcing plate 300, and the vibration bearing structure 100 are closely attached and rigidly connected by a connecting component.

[0040] In some embodiments, the vibration bearing structure 100 can be a subframe, in which case the vibration absorber 200 is fixed to one side of the subframe using the mounting structure disclosed in this application, such as... Figure 12 As shown. To facilitate understanding and explanation of the technical solution of this application, the vibration bearing structure 100 will be used as a subframe as a specific example for the following illustration.

[0041] It should be noted that the scope of the vibration bearing structure 100 is not limited to the subframe, but may also include other structural components that bear vibration, such as the suspension system, engine / transmission bracket, transmission system, and body.

[0042] In some embodiments, the vibration bearing structure 100 is provided with an installation area 110 for mounting the vibration absorber 200. This area provides a certain space for the assembly of the vibration absorber 200. In order to ensure that the vibration absorber 200 can be installed smoothly and form a stable connection with the vibration bearing structure 100, the periphery of the installation area 110 should avoid obstruction or interference from other structural components. The vibration absorber 200 is fixed to the installation area 110 by the above-mentioned installation structure.

[0043] In some embodiments, a mounting hole 111 is provided near the center of the mounting area 110 of the vibration bearing structure 100, and the vibration absorber 200 passes through the mounting hole 111 via a connecting component to achieve a fixed connection with the vibration bearing structure 100.

[0044] In some embodiments, the vibration absorber 200 includes a base plate 212 and an annular plate 210. The base plate 212 is located on the side of the vibration absorber 200 facing the reinforcing plate 300, and the annular plate 210 is located between the base plate 212 and the vibration bearing structure 100. An arc-shaped transition 211 is used between the base plate 212 and the annular plate 210. The annular plate 210, the arc-shaped transition 211, and the base plate 212 are integrally formed to constitute the main body of the damping plate of the vibration absorber 200. Figures 9~11 As shown, the cross-section of this attenuator is arched, and its function is to cooperate with the reinforcing plate 300 to disperse stress and improve structural strength.

[0045] Among them, the base plate 212 and the annular plate 210 are not coplanar. The base plate 212 and the annular plate 210 refer to the areas that remain flat (or nearly flat), while the arc transition 211 is a continuous curved surface structure connecting the base plate 212 and the annular plate 210. The dividing point of the three can be determined by the difference in structural morphology: the areas of the base plate 212 and the annular plate 210 have no obvious curvature (or very little curvature), while the area of ​​the arc transition 211 has continuously changing curvature.

[0046] In some embodiments, a through hole 212a is provided at the center of the base plate 212, and the vibration absorber 200 is fixedly connected to the vibration bearing structure 100 through a connecting component passing through the through hole 212a.

[0047] It should be noted that the specific structure of the vibration absorber 200 and the operating principle of the vibration absorber 200 in damping vibration by forming energy coupling with the vibration bearing structure 100 through its own vibration characteristics are all prior art, and their technical details are well known to those skilled in the art. Therefore, they need not be described in detail in this application. The improvement point of this application is only the damping plate on the side of the vibration absorber 200 facing the reinforcing plate 300 (specifically reflected in the structural design of the base plate 212, the arc transition 211 and the annular plate 210 and the matching relationship between the damping plate and the reinforcing plate 300), and does not involve any improvement to the existing structure and operating principle of the vibration absorber 200 itself.

[0048] In some embodiments, the reinforcing plate 300 is sandwiched between the vibration absorber 200 and the mounting area 110 of the vibration bearing structure 100: the side facing the vibration absorber 200 is tightly fitted with the base plate 212, while the side away from the vibration absorber 200 is tightly fitted with the mounting area 110 of the vibration bearing structure 100; the reinforcing plate 300 can increase the force-bearing area between the vibration bearing structure 100 and the vibration absorber 200, improve the stability of the connection between the two, and thus enhance the vibration transmission effect.

[0049] In some embodiments, a through hole 320 is provided at the center of the reinforcing plate 300, and the reinforcing plate 300 is fixedly connected to the vibration bearing structure 100 by a connecting component passing through the through hole 320.

[0050] In some embodiments, the reinforcing plate 300 may be in the shape of a regular form such as a circle, square, or polygon, or an irregular structure with a clearance notch at the edge to adapt to space requirements. However, its core design principle is to ensure effective contact with the recessed portion 211 base plate 212 and the installation area 110 of the vibration bearing structure 100, so as to increase the force bearing area and strengthen the connection strength.

[0051] In some embodiments, the reinforcing plate 300 is a cylindrical structure. The base plate 212 is also circular in shape. The circular reinforcing plate 300 can be precisely fitted to the circular base plate 212 to ensure that the two fit together to maximize the force-bearing area. At the same time, the circular structure can maximize the dispersion of vibration stress through its circumferentially uniform distribution, further improving the structural stability of the mounting point.

[0052] In some embodiments, the ratio of the thickness of the reinforcing plate 300 to the thickness of the mounting area 110 is greater than or equal to 1 and less than or equal to 2. If this ratio is too low, the reinforcing effect will be insignificant and the connection strength cannot be guaranteed; if the ratio is too high, the weight will increase significantly and the reinforcing effect will diminish marginally. This range ensures that the strength of the mounting point meets the requirements while controlling the overall weight to the maximum extent, balancing the strength requirements and the pressure of weight and cost.

[0053] Preferably, the thickness of the reinforcing plate 300 is set to twice the thickness of the mounting area 110 of the vibration bearing structure 100. This proportional design can significantly improve the structural strength of the mounting structure, ensure the stability of the connection between the vibration absorber 200 and the vibration bearing structure 100, and meet the requirements of high-strength installation; at the same time, it can maximize the strengthening effect while avoiding weight redundancy caused by excessive thickness, thus achieving a balance between strength improvement and weight control.

[0054] In some embodiments, the diameter of the reinforcing plate 300 is 30-34 mm, and the thickness is 1.5-2.5 mm. This size range ensures maximum reinforcement while avoiding excessive weight gain due to excessive thickness, thus achieving a balance between strength enhancement and weight control. It is worth noting that the specific values ​​for the diameter and thickness of the reinforcing plate 300 need to be determined comprehensively based on factors such as the actual vibration-bearing structure 100, the spatial conditions of the installation location, and the stress requirements, and are not limited to the ranges mentioned above.

[0055] In some embodiments, the diameter of the base plate 212 is 33-37 mm. The diameter of the base plate 212 corresponds to the diameter of the reinforcing piece 300, and the diameter of the base plate 212 is always larger than the diameter of the reinforcing piece 300, so that the reinforcing piece 300 can always be completely placed within the base plate 212, ensuring full fit between the two and improving stress transfer efficiency. It is worth noting that the diameter of the base plate 212 is not limited to the above range. The diameter of the base plate 212 is determined according to the diameter of the reinforcing piece 300. When the diameter of the reinforcing piece 300 changes, the diameter of the base plate 212 must also be adjusted accordingly.

[0056] Preferably, the diameter of the reinforcing sheet 300 is 32 mm, and the diameter of the base plate 212 is 35 mm.

[0057] Preferably, the thickness of the reinforcing sheet 300 is 2 mm, and the thickness of the mounting area 110 of the vibration bearing structure 100 is 1 mm.

[0058] In some embodiments, the vertical distance between the base plate 212 and the annular plate 210 along the axial direction of the base plate 212 is 1.5~2.5 mm; the thickness of the reinforcing piece 300 is greater than or equal to the vertical distance between the base plate 212 and the annular plate 210; this ensures that the reinforcing piece 300 can always be fully embedded in the arched recess formed by the base plate 212 and the arc transition 211 within the specified range, and is tightly fitted with the base plate 212 and the mounting area 110 of the vibration bearing structure 100, respectively, eliminating assembly gaps. It is worth noting that the vertical distance between the base plate 212 and the annular plate 210 is not limited to the above-mentioned range value; its value depends on the thickness of the reinforcing piece 300. When the thickness of the reinforcing piece 300 changes, the vertical distance between the base plate 212 and the annular plate 210 also needs to be adjusted accordingly.

[0059] Specifically, the thickness of the reinforcing plate 300 is 1.5 mm, and the vertical distance between the base plate 212 and the annular plate 210 is 1.5 mm; the thickness of the reinforcing plate 300 is 2 mm, and the vertical distance between the base plate 212 and the annular plate 210 is 1.5~2 mm; the thickness of the reinforcing plate 300 is 2.5 mm, and the vertical distance between the base plate 212 and the annular plate 210 is 2.5 mm; in short, it is necessary to ensure that both sides of the reinforcing plate 300 can always be tightly fitted with the base plate 212 and the installation area 110 of the vibration bearing structure 100.

[0060] In some embodiments, the connecting assembly consists of a mounting rod 220 and a fastener 230. The mounting rod 220 passes through the body of the vibration absorber 200, the through hole 212a of the base plate 212, the through hole 320 of the reinforcing plate 300, and the mounting hole 111 of the mounting area 110 of the vibration bearing structure 100. The fastener 230 is fixed to the mounting rod 220 and is located on the side of the vibration bearing structure 100 away from the reinforcing plate 300. During the fixing process, the fastener 230 applies an axial clamping force to the vibration absorber 200, the reinforcing plate 300, and the vibration bearing structure 100, causing the three to form a tightly fitted connection, ultimately constituting a rigid whole.

[0061] In some embodiments, such as Figure 4 As shown, an annular stop is provided at the end of the mounting rod 220 away from the fastener 230. The annular stop is used to provide axial limit during the process of the mounting rod 220 passing through various components, preventing the mounting rod 220 from falling off from one side of the vibration absorber 200 body. At the same time, when the fastener 230 applies clamping force, the annular stop can form a reverse force with the fastener 230, together firmly clamping the vibration absorber 200, the reinforcing plate 300 and the vibration bearing structure 100, ensuring the relative position of the three in the axial direction is stable and strengthening the connection reliability of the rigid whole.

[0062] In some embodiments, the mounting rod 220 has an external thread on the side near the vibration bearing structure 100, and the fastener 230 includes a nut and a washer integral with the nut. During assembly, the nut is fixedly connected to the end of the mounting rod 220 by engaging with the external thread, and during tightening, an axial clamping force is applied to the vibration absorber 200, the reinforcing plate 300 and the vibration bearing structure 100 to ensure that the three fit tightly together.

[0063] It is worth noting that the shim increases the contact area and facilitates the welding of the first weld bead 231; and to prevent relative rotation between the nut and the shim, they are integrated into one piece. It should be clarified that the outer edge of the fastener 230 refers to the outer edge of the shim.

[0064] In some embodiments, the reinforcing plate 300 and the fastener 230 are respectively welded and fixed to both sides of the vibration bearing structure 100: the reinforcing plate 300 is welded to the side of the vibration bearing structure 100 facing the vibration absorber 200, and the fastener 230 is welded to the side of the vibration bearing structure 100 away from the vibration absorber 200. The fastener 230 has at least one first weld bead 231 along its circumference on its outer edge, and the reinforcing plate 300 also has at least one second weld bead 310 along its circumference on its outer edge; the first weld bead 231 is located on the side of the vibration bearing structure 100 away from the vibration absorber 200, and the second weld bead 310 is located on the side of the vibration bearing structure 100 facing the vibration absorber 200.

[0065] This design, through the rigid fixation formed by welding, can prevent the fastener 230 from becoming loose and avoid relative rotation between the reinforcing plate 300 and the vibration absorber 200. On the basis of strengthening the connection stability, it further ensures the efficient transmission of vibration energy and ensures that the vibration reduction performance of the vibration absorber 200 is fully utilized.

[0066] In some embodiments, on any projection plane perpendicular to the axis of the mounting rod 220, the first weld bead 231 and the second weld bead 310 are staggered in the circumferential direction. This arrangement, by staggering the weld beads on both sides in the circumferential position, allows the first weld bead 231 and the second weld bead 310 to complement each other and cover the circumferential area (i.e., the angle range not covered by one side's weld bead can be filled by the weld bead on the other side), thereby maximizing the coverage of more of the circumference overall. This design achieves a welding and fixing effect that reaches or is close to the full circumference with the shortest possible total weld bead length, avoiding material waste and weight redundancy, and ensures that there are no obvious dead corners in the welding area through the staggered distribution, providing a stable and reliable force-bearing foundation for the connection between the fastener 230, the reinforcing plate 300, and the vibration bearing structure 100.

[0067] Furthermore, on any projection plane perpendicular to the axis of the mounting rod 220, the fan-shaped areas corresponding to the first weld bead 231 and the second weld bead 310 do not overlap. All combinations of the first weld bead 231 and the second weld bead 310 together form a complete 360° circumferential coverage. With this design, although the first weld bead 231 and the second weld bead 310 are independent short segments rather than continuous rings, when multiple first weld bead 231s and multiple second weld bead 310s are arranged in a staggered circumferential pattern, their overall coverage can completely cover the entire circumference of the fastener 230 and the reinforcing piece 300, equivalent to forming a seamless welding fixation in the circumferential direction. This design, while minimizing the total weld bead length, ensures optimal welding strength, achieving a balance between "shortest weld bead length" and "maximum connection strength."

[0068] In some embodiments, the number of first weld beads 231 and second weld beads 310 is one; wherein, the ratio of the arc length of the first weld bead 231 to the outer perimeter of the fastener 230 is 1 / 2, and the ratio of the arc length of the second weld bead 310 to the outer perimeter of the reinforcing plate 300 is 1 / 2; on any projection plane perpendicular to the axis of the mounting rod 220, the fan-shaped area corresponding to the first weld bead 231 and the fan-shaped area corresponding to the second weld bead 310 do not overlap, so that the first weld bead 231 and the second weld bead 310 can completely cover the entire circumference of the fastener 230 and the reinforcing plate 300, which is equivalent to forming a weld fixation without dead angles in the circumferential direction, and the overall length of the two types of weld beads is the shortest.

[0069] In some embodiments, such as Figure 8 As shown, there are two first weld beads 231 and two second weld beads 310. The ratio of the arc length of the first weld bead 231 to the outer perimeter of the fastener 230 is 1 / 4, and the ratio of the arc length of the second weld bead 310 to the outer perimeter of the reinforcing plate 300 is 1 / 4. The two first weld beads 231 and two second weld beads 310 are arranged in a cross-shaped staggered pattern on both sides of the vibration bearing structure 100, perfectly covering the entire circumference. That is, on any projection plane perpendicular to the axis of the mounting rod 220, the fan-shaped areas corresponding to the first weld bead 231 and the fan-shaped areas corresponding to the second weld bead 310 do not overlap. Since the perimeter of the reinforcing plate 300 is greater than that of the fastener 230, this dimensional difference combined with the cross-shaped staggered layout allows the segmented weld beads on both sides to form complementary coverage in the circumferential space. The area on the fastener 230 side not covered by the first weld bead 231 can be filled by the extension range of the second weld bead 310 on the reinforcing plate 300 side, ultimately achieving a seamless welding and fixing effect for the entire circumference. Meanwhile, the welds on both sides are linked by the vibration bearing structure 100, which allows them to borrow each other's connection strength, thereby significantly improving the overall connection strength of the installation structure while controlling the total length of the welds.

[0070] In some embodiments, there are three first weld beads 231 and three second weld beads 310. The ratio of the arc length of the first weld bead 231 to the outer perimeter of the fastener 230 is 1 / 6, and the ratio of the arc length of the second weld bead 310 to the outer perimeter of the reinforcing plate 300 is 1 / 6. The three first weld beads 231 and the three second weld beads 310 are staggered on both sides of the vibration bearing structure 100, covering the entire circumference. That is, on any projection plane perpendicular to the axis of the mounting rod 220, the fan-shaped area corresponding to the first weld bead 231 and the fan-shaped area corresponding to the second weld bead 310 do not overlap. This design can also achieve a welding fixation effect without dead angles in the circumferential direction, and the overall length of the two types of weld beads is the shortest.

[0071] In some embodiments, on any projection plane perpendicular to the axis of the mounting rod 220, all the first weld beads 231 and all the second weld beads 310 together cover the entire circumference, and the fan-shaped areas corresponding to the first weld beads 231 and the fan-shaped areas corresponding to the adjacent second weld beads 310 partially overlap. This design, although not the shortest overall length of the two types of weld beads, achieves higher strength and durability to meet higher engineering requirements.

[0072] In some embodiments, if the strength and durability requirements of the connection structure are not high, but the weight is sensitive, then on any projection plane perpendicular to the axis of the mounting rod 220, the first weld bead 231 and the second weld bead 310 do not need to cover the entire circumference, and there is a gap between the fan-shaped area corresponding to the first weld bead 231 and the fan-shaped area corresponding to the adjacent second weld bead 310.

[0073] In addition, this application also provides a vehicle, which includes a vehicle body, and a vibration bearing structure 100 and a vibration absorber 200 are provided in the vehicle body; wherein, the vibration absorber 200 is stably connected to the vibration bearing structure 100 through the installation structure disclosed above in this application.

[0074] This design enables the vibration absorber 200 to effectively reduce vibration: through the rigid fixing characteristics of the mounting structure, the vibration energy generated by the vibration bearing structure 100 (such as the subframe, suspension system, etc.) can be stably transmitted to the vibration absorber 200. The vibration amplitude is significantly reduced by the attenuation effect of the internal structure of the vibration absorber 200, thereby reducing the transmission of vibration to the vehicle body and the driving area, effectively improving the vehicle's ride comfort and NVH (noise, vibration and harshness) performance, and providing users with a more comfortable driving experience.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
