Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a cooling module suspension shock absorber and a vehicle. Background Technology

[0002] The cooling module in a vehicle's cooling system is usually mounted on the chassis. During vehicle operation, the chassis can exert a certain impact on the cooling module due to factors such as the excitation caused by uneven road surfaces and the vibration excitation generated by the normal operation of the cooling module.

[0003] To address this issue, researchers developed a cooling module suspension colloid. This colloid, a commonly used vibration damping structure, is mounted on the cooling module and connected to the vehicle body to reduce vibration impact. However, current cooling module suspension colloids on the market suffer from small size, high stiffness, and poor vibration isolation performance, leading to strong vibrations of the cooling module on the vehicle frame, which in turn causes noise and vibration inside the vehicle. Therefore, improvements are needed to address these problems. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a cooling module suspension damper, which can effectively reduce its own stiffness, improve vibration isolation performance, thereby reducing vehicle vibration and vibration noise, protecting the stability of the vehicle system, and improving the riding experience of passengers.

[0005] The present invention also aims to provide a vehicle having the above-mentioned cooling module suspension damper.

[0006] The cooling module suspension damper according to an embodiment of the present invention includes: Connecting plate; The vehicle body side shock absorber includes a first connecting column and a vibration isolation platform located on the same side of the connecting plate. The first connecting column is used to connect the vehicle body, and the vibration isolation platform is spaced apart from the first connecting column. A cooling-side damping section is provided on the connecting plate and is located on opposite sides of the vehicle body-side damping section on the connecting plate. The cooling-side damping section is used to connect the cooling module.

[0007] According to an embodiment of this utility model, the cooling module suspension damper consists of two parts: a vehicle-side damping section and a cooling-side damping section. The vehicle-side damping section has a first connecting post connected to the vehicle body, primarily resisting axial vibrations. Vibration isolation platforms are spaced apart on the outer side of the first connecting post. These platforms not only limit the radial displacement of the first connecting post and enhance radial vibration resistance, but also act as assembly limiters when the cooling-side damping section is assembled with the cooling module, facilitating installation and positioning. The cooling-side damping section is connected to the cooling module and primarily absorbs vibrations generated by the cooling module itself. Through the synergistic effect of the vehicle-side and cooling-side damping sections, this cooling module suspension damper effectively suppresses multi-directional vibration excitation generated during vehicle operation, improving system stability and comfort.

[0008] In some embodiments, the height of the first connecting column is greater than the height of the vibration isolation table.

[0009] In some embodiments, the first connecting post has a first connecting hole at its center, and at least one first groove spaced apart from the first connecting hole is provided on the end face of the first connecting post.

[0010] In some embodiments, there are at least two vibration isolation platforms, which are arranged circumferentially with the first connecting column as the center.

[0011] In some embodiments, at least one of the vibration isolation platforms forms a second groove on the side facing the first connecting post.

[0012] In some embodiments, the cooling-side vibration damping portion includes: a second connecting column, which is correspondingly disposed to the first connecting column and is used to connect the cooling module; and a vibration isolation rib, which is connected between the outer peripheral surface of the second connecting column and the connecting plate.

[0013] In some embodiments, the vibration isolation ribs are provided corresponding to the vibration isolation platform, and the height of the vibration isolation ribs gradually decreases in the direction away from the second connecting column.

[0014] In some embodiments, the cooling-side vibration damping portion further includes an outer ring rib, which surrounds the second connecting column, and the two ends of the vibration isolation rib are respectively connected to the second connecting column and the outer ring rib.

[0015] In some embodiments, the second connecting column has a second connecting hole at its center, and the inner wall of the second connecting hole has a damping groove, which is offset from the vibration isolation rib in the circumferential direction of the second connecting column.

[0016] The vehicle according to an embodiment of the present invention includes: a body and a cooling module.

[0017] According to any of the above, the cooling module suspension damper is connected to the vehicle body via the first connecting column and to the cooling module via the cooling-side damping part.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The following is for reference. Figures 1-5 Description of the cooling module suspension shock absorber 10 according to an embodiment of the present utility model.

[0025] According to an embodiment of the present invention, the cooling module suspension shock absorber 10 is referred to... Figures 1-3 , Figure 6 The system includes: a connecting plate 1, a body-side damping section 2, and a cooling-side damping section 3. The body-side damping section 2 is located on one side of the connecting plate 1 and includes a first connecting post 21 and a vibration isolation platform 22 located on the same side of the connecting plate 1. The first connecting post 21 is used to connect the body 30, and the vibration isolation platform 22 is spaced apart from the first connecting post 21. The cooling-side damping section 3 is located on the connecting plate 1 and on opposite sides of the body-side damping section 3. The cooling-side damping section 3 is used to connect the cooling module 2.

[0026] It should be noted that the cooling module suspension damper 10 of this application is a one-piece vulcanized molding: a manufacturing method that processes rubber raw materials into rubber products with specific shapes and structures in one step through a vulcanization process. That is to say, the connecting plate 1, the body side damping part 2, and the cooling module damping part 3 of the cooling module suspension damper 10 are all integrally vulcanized in the same mold through a vulcanization process, forming a structurally complete and functionally coordinated damping component. This damping component is used to elastically connect the cooling module 20 in the vehicle to the body 30, so as to reduce the impact of multi-directional vibrations generated during vehicle operation on the connection structure of the cooling module 20 and the body 30, and improve the structural stability and comfort of the whole vehicle.

[0027] like Figure 2 , Figure 4 , Figure 7 As shown, the connecting plate 1 serves as the intermediate base component of the cooling module suspension damper 10, supporting the overall damping unit. The upper and lower sides of the connecting plate 1 are respectively connected to the vehicle side damper 2 and the cooling side damper 3. The vehicle side damper 2 is located on one side of the connecting plate 1 and includes a first connecting column 21 and a vibration isolation platform 22. The first connecting column 21 is connected to the vehicle body 30 and mainly bears the axial load (vertical vibration caused by self-weight or up-and-down bumps). The vibration isolation platform 22 is used to suppress vibration from the radial direction and provide a buffer absorption function.

[0028] The cooling-side damping part 3 is located on the other side of the connecting plate 1. The cooling-side damping part 3 is connected to the cooling module 20 and mainly absorbs the working vibration of the cooling module 20 itself (such as vibration caused by coolant flow, fan operation, etc.). It works in conjunction with the vehicle body-side damping part 2 to isolate the vehicle from multi-directional vibration excitation from the road surface and engine during driving.

[0029] In some embodiments, refer to Figure 2 The height of the first connecting column 21 is greater than the height of the vibration isolation table 22.

[0030] like Figure 2 , Figure 6 As shown, when the vehicle body damping unit 2 is connected to the vehicle body 30, the outer side of the first connecting column 21 directly contacts the vehicle body 30 and bears the axial load, while the vibration isolation platform 22 does not contact the vehicle body 30, maintaining a certain gap. This gap allows the vibration isolation platform 22 to function when the vehicle is subjected to radial vibration or abnormal displacement during operation. In other words, when the first connecting column 21 tends to shift due to radial force, the vibration isolation platform 22 contacts the vehicle body 30 through elastic deformation and absorbs energy, thereby suppressing the transmission of radial vibration. Under normal installation conditions (without abnormal vibration), the vibration isolation platform 22 does not contact the vehicle body 30, thus avoiding unnecessary frictional loss, extending the service life of the cooling module suspension damping body 10, and ensuring that the axial load is reliably transmitted mainly by the first connecting column 21.

[0031] In addition, during the assembly of the first connecting pillar 21 with the vehicle body 30, to ensure the reliability of the connection structure and prevent the first connecting pillar 21 from coming off during use, a draft angle design is applied to the outer side of the first connecting pillar 21. Specifically, the draft angle of the outer cylindrical side of the first connecting pillar 21 can be set according to design requirements. This draft angle design satisfies the smooth demolding requirements of the cooling module suspension damper 10 during injection molding, avoiding deformation or damage to the first connecting pillar 21 due to excessive demolding resistance, while also forming a tight engagement effect after the first connecting pillar 21 and the cooling module 20 are assembled. A smaller draft angle can effectively limit the corresponding mounting hole in the cooling module 20. Through the elastic deformation of the material and the fit tolerance, the first connecting pillar 21 is firmly embedded in the cooling module 20, achieving an efficient and reliable mechanical connection, effectively improving the overall structural stability and durability of the cooling module 20. Optionally, the draft angle of the outer cylindrical side of the first connecting pillar 21 can be 1 to 2 degrees.

[0032] In some embodiments, refer to Figure 3 The first connecting post 21 has a first connecting hole 211 at its center, and at least one first groove 212 spaced apart from the first connecting hole 211 on its end face.

[0033] like Figure 3 , Figure 6 As shown, the first connecting hole 211 penetrates the central axis of the first connecting post 21 and is used to connect to the cooling module 20, bearing the main axial load of the cooling module 20. Specifically, the vertical vibration load generated by the cooling module 20 during vehicle operation is directly applied to the inner wall of the first connecting hole 211 through the connector passing through the first connecting hole 211. The vibration load is then borne by the solid part of the first connecting post 21 where the first connecting hole 211 is located and transmitted and distributed to the entire cooling module suspension damper 10, which absorbs the vibration.

[0034] The upper end of the first connecting post 21 is recessed downwards to form a first groove 212. The first groove 212 is located on the upper end face of the first connecting post 21, spaced apart from the first connecting hole 211, and is not directly connected to the first connecting hole 211. When the cooling module 20 is installed through the first connecting hole 211 and transmits axial load, the area where the first groove 212 is located has relatively low stiffness and can produce more moderate elastic deformation. This optimizes the overall stress transition and vibration response characteristics of the first connecting post 21 to a certain extent. The first groove 212 effectively reduces the overall stiffness of the vehicle body damping part 2 without affecting the axial bearing function of the first connecting hole 211.

[0035] In some embodiments, refer to Figure 3There are at least two vibration isolation platforms 22, which are arranged at intervals along the circumference with the first connecting column 21 as the center.

[0036] Vibration isolation platforms 22 are spaced around the periphery of the first connecting column 21, covering multiple radial directions. This allows them to comprehensively capture and absorb multi-angle radial vibrations generated during vehicle operation (such as lateral swaying caused by turning and bumps, and lateral impacts). The synergistic effect of multiple vibration isolation platforms 22 significantly improves the overall radial vibration isolation performance. Furthermore, when subjected to radial vibration impacts, the multiple platforms 22 share the impact energy, resulting in a greater stress on each individual platform 22. Therefore, multiple platforms 22 effectively reduce the risk of stress concentration and ensure the stability of each platform. The balanced force distribution of the 22 enhances the stability and durability of the cooling module suspension damper 10 structure. In addition, the circumferential arrangement of the vibration isolation platform 22 is highly compatible with the vulcanization molding process, requiring no additional assembly or complex processing. The cooling module suspension damper 10 has a simple structure and high functional integration. Under the premise of ensuring the stable transmission of the axial load of the first connecting column 21 (such as the up-and-down bump load during vehicle operation), it achieves precise suppression of complex multi-directional vibration environment, significantly enhancing the adaptability and reliability of the cooling module suspension damper 10 in actual working conditions.

[0037] In some embodiments, refer to Figure 3 At least one vibration isolation platform 22 forms a second groove 212 on the side facing the first connecting post 21.

[0038] The introduction of the second groove 212 reduces the amount of solid material in the area of ​​the vibration isolation table 22 facing the first connecting column 21. Without affecting the overall assembly, the arrangement of the second groove 212 effectively reduces the structural stiffness of the vibration isolation table 22. Specifically, when radial vibration occurs during vehicle operation, the area where the second groove 212 is located has lower stiffness and is more prone to elastic deformation after being subjected to force, thereby improving the vibration isolation table 22's ability to buffer and absorb radial vibration. At the same time, it avoids stress concentration caused by excessive stiffness of the vibration isolation table 22. The circumferential arrangement of the second groove 212 can optimize the overall stress distribution of the vibration isolation table 22 and improve its durability.

[0039] In summary, as Figure 1 , Figure 3 , Figure 4As shown, a first groove 211 is provided on the first connecting column 21 of the body side damping part 2, and a second groove 212 is provided on the vibration isolation platform 22. The two grooves reduce the stiffness of the body side damping part 2 in both the vertical and horizontal directions. Since the cooling module suspension damping body 10 is integrally vulcanized, the mold design of the cooling module suspension damping body 10 can adopt the upper and lower mold opening method, without the need for a complex core pulling structure. This simplifies the mold manufacturing process of the cooling module suspension damping body 10, reduces production costs, and ensures the molding accuracy and structural stability of the cooling module suspension damping body 10.

[0040] In some embodiments, refer to Figure 2 , Figure 4 , Figure 7 The cooling-side vibration damping part 3 includes a second connecting column 31 and a vibration isolation rib 32. The second connecting column 31 is correspondingly arranged with the first connecting column 21 and is used to connect the cooling module 20. The vibration isolation rib 32 is connected between the outer peripheral surface of the second connecting column 31 and the connecting plate 1.

[0041] The cooling-side damping section 3 is directly connected to the cooling module 20 via the second connecting column 31. The second connecting column 31 is correspondingly set with the first connecting column 21 to achieve structural matching and force balance, thereby ensuring the stability of the power transmission path. In addition, the vibration isolation ribs 32 set between the outer peripheral surface of the second connecting column 31 and the connecting plate 1 can effectively absorb and isolate the vibration generated by the cooling module 20 during operation. The vibration isolation ribs 32 can absorb and weaken the vibration energy through the deformation of their own structure, reducing the transmission of vibration load to the connecting plate 1 and the vehicle-side damping section 2. The vibration isolation ribs 32 improve the damping effect between the cooling module 20 and the cooling-side damping section 3, enhancing the stability and reliability of the overall structure.

[0042] Furthermore, such as Figure 4 As shown, the vibration isolation rib 32 is correspondingly arranged with the vibration isolation table 22, and the height of the vibration isolation rib 32 gradually decreases in the direction away from the second connecting column 31.

[0043] One end of the vibration isolation bar 32 starts from the outer peripheral surface of the second connecting column 31, and the amount of protrusion gradually decreases along the extension direction of the vibration isolation bar 32 (towards the connecting plate 1 or away from the center of the second connecting column 31). That is, the vibration isolation bar 32 is the highest and most prominent at the point closest to the second connecting column 31, and then the height of the vibration isolation bar 32 gradually decreases as it moves away from the second connecting column 31, gradually transitioning to the outer ring bar 33. The vibration isolation bar 32 has a large structural height at its highest point, which can provide stronger support and vibration absorption capacity. As the height of the vibration isolation bar 32 gradually decreases as it moves away from the second connecting column 31, vibration energy is gradually absorbed, optimizing the stress state of the structure.

[0044] In some embodiments, refer to Figure 4The cooling side vibration damping part 3 also includes an outer ring rib 33, which surrounds the second connecting column 31, and the two ends of the vibration isolation rib 32 are respectively connected to the second connecting column 31 and the outer ring rib 33.

[0045] One end of the vibration isolation rib 32 is connected to the second connecting column 31, and the other end of the vibration isolation rib 32 is connected to the outer ring rib 33. The outer ring rib 33 is arranged around the other end of each vibration isolation rib 32, forming a stable outer reinforcement structure. The cooperation between the outer ring rib 33 and the vibration isolation rib 32 enhances the stability and reliability of the cooling side damping part 3 against vibration excitation.

[0046] In some embodiments, refer to Figure 5 , Figure 7 The second connecting column 31 has a second connecting hole 311 at its center. The inner wall of the second connecting hole 311 has a damping groove 3111. The damping groove 3111 and the vibration isolation rib 32 are staggered in the circumferential direction of the second connecting column 31.

[0047] The second connecting column 31 is connected to the cooling module 20. Specifically, the second connecting hole 311 at the center of the second connecting column 31 contacts and connects with the cooling module 20. The inner wall of the second connecting hole 311 has a damping groove 3111, which reduces the contact stiffness of the area connected to the cooling module 20, thereby weakening vibration transmission. The damping groove 3111 and the vibration isolation rib 32 are staggered circumferentially on the second connecting column 31 to avoid localized stiffness concentration, optimize the vibration transmission path, improve the overall vibration damping effect, and ensure the reliability of the structure.

[0048] According to an embodiment of the present utility model, the vehicle 100, with reference to... Figure 2 , Figure 6 and Figure 7 It includes: a body 30 and a cooling module 20. The cooling module suspension damper 10 is connected to the body 30 via a first connecting column 21, and is connected to the cooling module 20 via a cooling-side damper 3.

[0049] Specifically, the outer side of the first connecting post 21 is connected to the connecting plate 40, and the connecting plate 40 is then connected to the vehicle body 30 to realize the installation and fixation between the cooling module suspension damper 10 and the vehicle body 30. The second connecting hole 311 of the second connecting post 31 in the cooling side damping part 3 is connected to the cooling module 20 to realize the connection between the cooling module 20 and the cooling side damping part 3, so as to ensure the stable positioning and installation of the cooling module 20 in the vehicle 100.
