Description

Technical Field

[0001] This utility model relates to the field of suspension system technology, and in particular to a support assembly, a support connection assembly, a suspension system, and a vehicle for use in suspension systems. Background Technology

[0002] To further improve suspension performance, in addition to selecting appropriate suspension type, suspension parameters, and shock absorber type, it is also necessary to optimize the structural design of the shock absorber upper support. The shock absorber upper support is responsible for fixing the upper part of the suspension system to the vehicle body, ensuring that the suspension system does not shift or loosen due to vibration or impact during vehicle operation. A good support can effectively absorb and disperse vibrations from the road surface, improving the shock absorber's damping effect and thus significantly improving vehicle ride comfort.

[0003] When the suspension system encounters adverse conditions, such as bumpy roads or violent vehicle movement, the shock absorber piston rod may wobble. This results in a larger torque at the upper support, leading to high yaw stiffness and a tendency for localized abnormal noises, affecting vehicle ride comfort. Yaw stiffness is a crucial parameter affecting vehicle handling stability and ride comfort. Excessive yaw stiffness causes the vehicle to be overly stiff during cornering, reducing ride comfort; conversely, insufficient yaw stiffness causes excessive body roll during cornering, compromising driving safety. Therefore, optimizing yaw stiffness by altering the connection method between the shock absorber and the vehicle body is an important research direction for improving vehicle performance.

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. Therefore, one objective of this invention is to provide a support assembly for a suspension system with a large swing angle in its movable structure, which reduces the rotational stiffness of the support assembly and improves stability and reliability.

[0051] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 and Figure 2 Description of a support assembly 100 for a suspension system 300 according to an embodiment of the present invention.

[0052] like Figure 1 As shown, the support assembly 100 for a suspension system 300 according to the first aspect embodiment of the present invention includes a mounting bracket 1 and a movable structure 2.

[0053] Specifically, the movable structure 2 is movably mounted on the mounting bracket 1. The movable structure 2 is swaying relative to the mounting bracket 1. The maximum swaying angle of the movable structure 2 relative to the mounting bracket 1 is θ, where θ satisfies: θ>18°.

[0054] For example, refer to Figure 1 The movable structure 2 is mounted on the mounting bracket 1 and is swayable relative to the mounting bracket 1. When the support assembly 100 is used in the suspension system 300, the suspension system 300 is connected to the vehicle body 401 through the support assembly 100. That is, the support assembly 100 is located between the shock absorber 302 of the suspension system 300 and the vehicle body 401. When the support assembly 100 is used in the suspension system 300, the upper end of the piston rod 3022 of the shock absorber 302 is connected to the support assembly 100.

[0055] With this configuration, since the movable structure 2 can swing relative to the mounting bracket 1, when the vehicle encounters bumps or turns, the swing of the shock absorber 302 can simultaneously drive the mounting bracket 1 to swing. This interaction between the movable structure 2 and the mounting bracket 1 allows the shock absorber 302 to drive the elastic components of the suspension system 300, such as the air spring 303 (or a coil spring, and other components), and the mounting bracket 1 as a whole, to swing relative to the vehicle body 401. This reduces the pressure exerted by the swing of the shock absorber 302 on other components on the support assembly 100, such as rubber bushings, extending the service life of the rubber bushings. Furthermore, the swing of the movable structure 2 adapts to changes in force, avoiding excessive friction, tension, and stress concentration between components caused by rigid connections. This effectively reduces wear on various components of the suspension system 300, such as the support assembly 100 and suspension arms, extending the service life of the support assembly 100 and components in the suspension system 300, and reducing vehicle maintenance costs.

[0056] Simultaneously, the movable connection between the support assembly 100 and the vehicle body 401 is achieved, increasing the degrees of freedom of the support assembly 100, shock absorber 302, and air spring 303, reducing yaw stiffness, and lowering the stiffness of the air spring 303, shock absorber 302, and support assembly 100. This optimizes the damper friction resistance problem caused by yaw stiffness, thereby improving the stability of the vehicle body 401 and enhancing the buffering effect of the suspension system 300. Furthermore, during the oscillation of the air spring 303 with the shock absorber 302, the volume and pressure within the air spring bladder 3031 of the air spring 303 are approximately the same, and the air spring 303 does not deform relative to the shock absorber 302, improving the sealing and buffering performance of the air spring 303 and enhancing the stability and reliability of the suspension system 300. The synchronized yaw of the support assembly 100, shock absorber 302, and air spring 303 effectively reduces or even eliminates the internal lateral forces among them, avoiding damage such as wear and tear on materials causing abnormal noise.

[0057] Furthermore, the swinging motion of the movable structure 2 relative to the mounting bracket 1 improves the steering flexibility of the wheels. In addition, the swinging motion of the movable structure 2 helps the vehicle maintain good driving stability and handling under various road conditions, allowing the driver to more accurately control the vehicle's direction and react promptly to emergencies, thereby improving driving safety. Moreover, when the vehicle travels on different road surfaces, the wheels will move in different directions and amplitudes due to road undulations. At this time, the swinging function of the movable structure 2 allows the wheels to maintain a proper connection with the body 401 during vertical movement, lateral tilting, or forward and backward displacement, ensuring that the suspension system 300 effectively buffers and filters road bumps, making the vehicle ride smoother and improving ride comfort.

[0058] For example, combining Figure 5 In motion, the support assembly 100 can be aligned with the shock absorber 302 and the air spring 303 around the central axis of the shock absorber 302 (i.e., Figure 5 The straight line R in the diagram oscillates. Line A represents the extreme position after oscillating to the left by an angle θ, and line B represents the extreme position after oscillating to the right by an angle θ (to avoid visual interference, the extreme oscillation positions of the shock absorber 302 and air spring 303 are not shown in the diagram). Therefore, by adding a support assembly 100 between the suspension system 300 and the body 401, the degrees of freedom of the shock absorber 302, air spring 303, and support assembly 100 are increased, and the stiffness between the air spring 303 and support assembly 100 is reduced. This optimizes the damper friction resistance problem caused by oscillation stiffness, thereby improving the stability of the body 401 and enhancing the buffering effect of the suspension system 300.

[0059] In traditional technology, the maximum swing angle of shock absorbers is 15°-18°. Therefore, through the cooperation of the movable structure 2 and the mounting bracket 1, the maximum swing angle θ of the movable structure 2 relative to the mounting bracket 1 can reach θ > 18°. This larger swing angle effectively reduces the yaw stiffness of the support assembly 100, thereby optimizing the damper friction resistance problem caused by yaw stiffness, improving the stability of the vehicle body 401, and enhancing the cushioning effect of the suspension system 300. Furthermore, during the rotation of the rear wheels, the support assembly 100 can rotate axially around the movable structure 2, reducing the rotational stiffness of the support assembly 100 and improving the comfort of the suspension system 300. Simultaneously, it improves the sealing and cushioning performance of the air spring 303, enhancing the stability and reliability of the suspension system 300.

[0060] According to the present invention, the support assembly 100 for the suspension system 300 has a maximum swing angle θ of the movable structure 2 relative to the mounting bracket 1 that can reach θ > 18°. This large swing angle effectively reduces the yaw stiffness of the support assembly 100, thereby optimizing the damper friction resistance problem caused by the yaw stiffness, improving the stability of the vehicle body 401, and enhancing the buffering effect of the suspension system 300. Simultaneously, it can improve the sealing and buffering performance of elastic components such as the air spring 303, enhancing the stability and reliability of the suspension system 300. Furthermore, the movable structure 2 and the mounting bracket 1 work together to allow the shock absorber 302 to swing relative to the vehicle body 401, thereby reducing the pressure exerted by the shock absorber 302 on other components of the support assembly 100 and extending the service life of the support assembly 100.

[0061] According to some embodiments of this utility model, refer to Figure 5Furthermore, θ further satisfies: 18°<θ≤30°. That is to say, when the mounting bracket 1 is subjected to the action of the vibration damper 302, the range of swing of the mounting bracket 1 relative to the movable structure 2 is relatively large, up to a maximum of 30°.

[0062] This reduces the yaw stiffness of the support assembly 100, further optimizing the damper friction resistance problem caused by yaw stiffness, thereby improving the stability of the vehicle body 401 and enhancing the buffering effect of the suspension system 300. Furthermore, the movement of the mounting bracket 1 and the movable structure 2 is more flexible, allowing the support assembly 100 to flexibly cope with various operating conditions, further improving the performance of the support assembly 100.

[0063] Preferably, θ further satisfies: 28°<θ≤30°.

[0064] In traditional technology, the shock absorber and upper support are rigidly connected, resulting in a small maximum swing angle. With the support assembly 100 of this invention, the shock absorber 302 has a larger maximum swing angle θ relative to the mounting bracket 1 due to the movable structure 2. This is more conducive to reducing its yaw stiffness, thereby better optimizing the damper friction resistance problem caused by yaw stiffness, improving vehicle driving stability and enhancing driving comfort. The performance of the support assembly 100 is optimal when the maximum swing angle θ of the movable structure 2 relative to the mounting bracket 1 is set between 28° and 30°.

[0065] According to some embodiments of this utility model, refer to Figure 1 The movable structure 2 can also rotate relative to the mounting bracket 1. For example, in Figure 1 In the example, the movable structure 2 is rotatable relative to the mounting bracket 1 about the central axis of the movable structure 2, thereby enabling the movable structure 2 to move in multiple ways relative to the mounting bracket 1.

[0066] This configuration allows the support assembly 100, when used in the vehicle's suspension system 300, to allow components such as the shock absorber 302 and mounting bracket 1 of the suspension system 300 to rotate relative to the vehicle body 401 when encountering road bumps during vehicle operation. This adapts to the vertical movement and steering of the wheels, optimizing yaw stiffness and improving ride smoothness. Furthermore, it effectively reduces wear on the support assembly 100 and also reduces vibration and noise. In addition, as the movable structure 2 rotates relative to the mounting bracket 1, the contact point constantly changes, resulting in more even wear between the movable structure 2 and the mounting bracket 1, reducing localized wear and extending the service life of the movable structure 2. Moreover, when the support assembly 100 is subjected to external forces, the movable structure 2 can rotate according to the direction of the force to adjust its posture, distributing the force evenly across the mounting bracket 1 and other connecting components. This avoids stress concentration, effectively reducing the risk of damage to the support assembly 100 due to excessive localized stress and extending its service life.

[0067] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 The movable structure 2 includes a movable part 21 and at least one fixed part 22. Specifically, the movable part 21 is movably fitted within the mounting bracket 1. One end of the fixed part 22 is connected to the movable part 21, and the other end of the fixed part 22 extends out of the mounting bracket 1. The term "at least one" means that there is at least one fixed part 22, but there may also be multiple fixed parts 22.

[0068] For example, in Figure 2 In the example, taking the fixed part 22 located on the right side of the movable part 21 as an example, along the axial direction of the movable structure 2, the left end of the fixed part 22 is connected to the right end of the movable part 21, and the right end of the fixed part 22 extends to the outside of the mounting space. As a result, the movable part 21 can swing or rotate at multiple angles within a certain range, thereby reducing the yaw stiffness of the support assembly 100 and eliminating the lateral movement of the support assembly 100 relative to the air spring 303 after being subjected to a lateral impact.

[0069] Furthermore, the fixing part 22 ensures that the movable part 21 maintains a stable position when it is not in motion, providing an accurate reference for the rotation of the movable part 21. Moreover, by having the other end of the fixing part 22 extend beyond the mounting bracket 1, it facilitates the connection of the support assembly 100 to other components via the fixing part 22 of the movable structure 2, thereby facilitating the assembly of the movable structure 2 with the mounting bracket 1 and ensuring the movable structure 2 is fixed within a certain range. On the other hand, the fixing part 22 defines the rotation direction of the movable part 21, for example, facilitating the rotation of the movable part 21 around the axis connecting the movable part 21 and the fixing part 22, thereby improving the stability and reliability of the support assembly 100, extending its service life, and reducing the probability of failure. Furthermore, it reduces the swaying or vibration of the movable part 21 during installation, lowers installation difficulty, and improves installation accuracy.

[0070] According to some embodiments of this utility model, refer to Figure 1 and Figure 2 There are two fixed parts 22, which are respectively connected to the opposite sides of the movable part 21. The movable structure 2 can swing relative to the mounting bracket 1 along the axis where the two fixed parts 22 and the movable part 21 are located.

[0071] For example, in Figure 1 and Figure 2 In the example, a fixed part 22 is connected to each of the left and right sides of the movable part 21. The ends of the two fixed parts 22 closest to the movable part 21 are connected to the movable part 21, while the ends of the two fixed parts 22 furthest from the movable part 21 extend out of the mounting bracket 1. This configuration allows the two fixed parts 22 to be connected and fixed to different components, more securely mounting the support assembly 100 to the relevant structures of the vehicle. This effectively limits the displacement and sway of the support assembly 100 during vehicle operation, ensuring accurate position and posture even under complex stress conditions, and providing stable support for the normal operation of the suspension system 300. Furthermore, the connection of the fixed parts 22 at both ends to other components allows for more precise control of the range of motion and rotation direction of the movable structure 2, facilitating the control of the support assembly 100's movement. This enables the movable structure 2 to move precisely according to design requirements, ensuring the suspension system 300's precision in controlling wheel movement, thereby improving vehicle handling performance and driving stability. In addition, during the installation process, the two fixed parts 22 provide a clear positioning reference for the installation of the movable structure 2, thereby enabling the rapid and accurate installation of the support assembly 100 and improving the installation accuracy.

[0072] According to some embodiments of this utility model, refer to Figure 2 The outer surface of the movable part 21 is formed as a sphere. For example, in Figure 2 In the example, the outer surface of the movable part 21 is spherical, and the shape of the movable part 21 is adapted to the internal space of the mounting bracket 1. That is, the fit between the movable part 21 and the internal space of the mounting bracket 1 is a spherical fit.

[0073] This configuration allows the spherical geometry to rotate in multiple directions, providing a wide range of degrees of freedom for the connected components. Furthermore, when the movable structure 2 contacts and moves relative to other components, the contact area between the spherical surface and the contact surface is relatively small, and the contact point is constantly changing. According to tribological principles, a smaller contact area helps reduce friction, while the constantly changing contact point ensures that wear is evenly distributed on the surface of the movable structure 2, avoiding excessive localized wear and thus extending the service life of the movable structure 2. For example, in a vehicle's suspension system 300, during vehicle operation, the movable structure 2 can adapt to various wheel movements by rotating while bearing the vehicle's weight and road impacts, reducing friction and wear between components. Additionally, it can reduce abnormal noise during wheel steering, improving the noise, vibration, and harshness (NVH) performance of the vehicle's suspension system 300. Moreover, it can reduce the yaw stiffness of the shock absorber 302 and support assembly 100 due to rear-wheel steering, improving vehicle ride smoothness and passenger comfort.

[0074] According to some embodiments of this utility model, refer to Figure 1 The mounting bracket 1 includes a bracket body 11 and a plurality of mounting legs 12. Specifically, a movable space 111 is formed on the bracket body 11, and the movable structure 2 is movably disposed within the movable space 111. One end of the plurality of mounting legs 12 is connected to the bracket body 11, and the other ends of the plurality of mounting legs 12 are arranged at intervals between each other. In the description of this utility model, "plural" means two or more.

[0075] For example, refer to Figure 1 Mounting bracket 1 includes components located in the height direction of the support assembly 100 (e.g., ...). Figure 1The bracket body 11 (in the direction indicated by arrow D) is located on the upper side, and multiple mounting feet 12 are located on the lower side. The bracket body 11 is located on the side of the mounting feet 12 closest to the vehicle body 401. The movable space 111 can be used to install and accommodate the movable structure 2. Thus, the movable structure 2 can rotate flexibly within the movable space 111 of the mounting bracket 1, so as to facilitate the movement of the movable structure 2 and the mounting bracket 1, thereby facilitating the flexible use of the support assembly 100. For example, when the vehicle is cornering, the movement of the movable structure 2 can keep the wheels at the correct steering angle and posture, improving the vehicle's handling performance. Moreover, the movable space 111 can provide some cushioning for the movable structure 2 when it is subjected to impact, thereby reducing the wear of the movable structure 2 and extending its service life. In addition, when the wheels encounter bumps or potholes, the impact force is transmitted to the movable structure 2. The micro-movement of the movable structure 2 within the movable space 111 can absorb some energy, playing a role in cushioning and shock absorption, reducing the vibration transmitted to the vehicle body 401, and improving ride comfort.

[0076] For example, in Figure 1 and Figure 2 In the example, three mounting feet 12 are provided. The upper ends of the three mounting feet 12 are connected to the bracket body 11, and the lower ends of the three mounting feet 12 are arranged at intervals. Thus, the mounting bracket 1 can be connected to other components, such as by threaded connections, through multiple mounting feet 12, thereby reducing the production and installation difficulty of the mounting bracket 1 while ensuring installation stability. Optionally, the multiple mounting feet 12 are respectively connected to other components, such as the support base 3, through connectors 5, with the connectors 5 passing through the mounting feet 12. This makes the connection between the mounting feet 12 and other components more stable, and the installation is easier and simpler. Furthermore, it reduces the amount of connectors 5 used, which helps reduce production costs and facilitates the rapid installation of the mounting bracket 1. In addition, the support assembly 100 has a simple structure and does not occupy lateral space, which helps improve the overall vehicle space utilization and also helps optimize the overall vehicle layout design.

[0077] According to an optional embodiment of the present invention, referring to Figure 1 The other ends of the multiple mounting legs 12 are arranged at non-uniform intervals in a plane parallel to the axis of the movable structure 2.

[0078] For example, refer to Figure 1 The three mounting legs 12 are located away from the movable structure 2 along the circumference of the movable structure 2 (i.e., Figure 3The mounting feet 12 are spaced apart (in the direction indicated by the middle arrow C). This arrangement allows the movable structure 2 to withstand forces from different directions when the vehicle is in motion. The non-equidistant mounting feet 12 can distribute these forces more effectively across the body structure 401 based on their characteristics. For example, increasing the number of mounting feet or reducing their spacing in areas of higher stress can better withstand and transmit these forces, preventing excessive local stress and improving the strength and durability of the connection between the movable structure 2 and the body 401. Furthermore, vehicle interior space is limited, especially around the suspension system 300 where numerous components need to be arranged. The non-equidistant mounting feet 12 can better adapt to complex spatial environments, avoiding other components and allowing the movable structure 2 to be installed more compactly on the body seat 4, improving overall vehicle space utilization and optimizing the overall vehicle layout. Additionally, it reduces installation difficulty, improves installation efficiency and accuracy, and facilitates later inspection and maintenance. It should be noted that the spacing of the multiple mounting feet 12 can be set according to the design of the connection of the shock absorber 302 or other connecting components support assembly 100, and no specific limitation is made here.

[0079] According to some embodiments of this utility model, refer to Figure 1 The plurality of mounting feet 12 include at least one first mounting foot 121 and at least one second mounting foot 122, the first mounting foot 121 and the second mounting foot 122 being located on opposite sides of the radial direction of the movable structure 2.

[0080] For example, in Figure 1 In the example, the mounting bracket 1 includes two first mounting legs 121 located radially on the front side of the movable structure 2 and a second mounting leg 122 located radially on the rear side of the movable structure 2. Thus, the two first mounting legs 121 and the second mounting leg 122 together form a claw-shaped mounting bracket 1 structure, thereby creating a stable triangular support structure. This effectively improves the stability of the support assembly 100, reduces swaying and displacement during use, and ensures accurate position and posture during operation. Furthermore, it facilitates the installation and disassembly of the mounting bracket 1, making subsequent inspection and maintenance easier. In addition, while meeting the requirements for support and stability performance, the claw-shaped structure reduces material usage compared to some other complex support structures, thereby reducing the weight of the mounting bracket 1, lowering production costs, and also contributing to the lightweight design of the entire suspension system 300.

[0081] According to some embodiments of this utility model, refer to Figure 1 The support assembly 100 further includes a support base 3, which is connected to the mounting bracket 1 via a plurality of mounting feet 12. For example, combined with Figure 1The support base 3 has three bosses 311 corresponding to the mounting legs 12. These bosses 311 are connected to the mounting legs 12 via connectors 5. This creates a stable connection between the support base 3 and the mounting bracket 1, effectively reducing the possibility of separation during use and ensuring the performance stability of the support assembly 100. Furthermore, the support base 3 has a simple structure, making it easy to manufacture and install.

[0082] According to some embodiments of this utility model, refer to Figure 1 The support base 3 includes a first support portion 31 and a second support portion 32. Specifically, the first support portion 31 is connected to a plurality of mounting feet 12. The second support portion 32 is connected to the outer periphery of the first support portion 31, and a plurality of connecting holes 321 are formed on the second support portion 32, which are arranged at intervals along the circumference of the first support portion 31.

[0083] For example, refer to Figure 1 The three protrusions 311 on the first support part 31 are connected to the three mounting feet 12 one by one. Thus, the support base 3 forms a stable connection with the mounting feet 12 through the first support part 31, which improves the overall structural stability of the support assembly 100 and ensures the performance stability of the support assembly 100 during use.

[0084] For example, in Figure 1 In the example, the second support 32 is connected to the side of the first support 31 away from the vehicle body 401. The second support 32 can be configured in an annular shape, and the plurality of connecting holes 321 on the second support 32 are along the circumference of the first support 31 (i.e., Figure 3 The connecting holes 321 are arranged at intervals (in the direction indicated by the middle arrow C). For example, multiple connecting holes 321 can be arranged at equal intervals along the circumference of the first support part 31. Bolts 322 can be inserted into each of the multiple connecting holes 321. The second support part 32 can be connected to other components, such as the air spring 303 of the suspension system 300, through the cooperation of multiple bolts 322 and multiple connecting holes 321. This facilitates a quick and stable connection between the second support part 32 and other components, thereby improving the connection stability between the support assembly 100 and the suspension system 300, reducing installation difficulty, and improving installation efficiency. In addition, the connecting holes 321 have a simple structure and are easy to process. For example, the shape of the connecting holes 321 can be square-round, round, etc., but is not limited to these. It should be noted that the arrangement of the connecting holes 321 on the second support part 32 can be set according to the actual situation, and is not specifically limited here.

[0085] According to some embodiments of this utility model, refer to Figure 2The support assembly 100 also includes a support frame 13, an inner membrane 14, a rubber dust cover 15, a baffle 16, an outer clamp 17, and an inner clamp 18. The support frame 13 is located inside the mounting bracket 1 and on the outer periphery of the movable structure 2. Therefore, the support frame 13 provides structural support for the support assembly 100, improving its stability. Furthermore, it provides a mounting base for structures such as the inner membrane 14 and the rubber dust cover 15, reducing installation difficulty and improving installation accuracy.

[0086] An inner membrane 14 is disposed between the movable structure 2 and the support frame 13. Two rubber dust covers 15 are provided, one end of which is connected to the fixing part 22 at both axial ends of the movable structure 2, and the other end of which is bent and extended to the axial end face of the support frame 13. Thus, the rubber dust covers 15 can provide dust protection and sealing for the support assembly 100, thereby improving the sealing between the movable structure 2 and the support base 3, which is beneficial for the long-term use of the support assembly 100. Furthermore, the inner membrane 14 can absorb the stress generated during the movement of the movable structure 2, reducing damage to the mounting bracket 1 and the movable structure 2, which is beneficial for the long-term stable use of the support assembly 100.

[0087] The outer clamp 17 is fitted onto the outer circumferential surface of one end of the rubber dust cover 15, and the inner clamp 18 is fitted onto the outer circumferential surface of the other end of the rubber dust cover 15. Thus, the outer clamp 17 securely fixes external components such as the rubber dust cover 15 to the support assembly 100, preventing displacement or detachment during operation and ensuring the sealing effect of the dust cover and the stability of the overall structure. The inner clamp 18 secures internal components of the support assembly 100, such as the inner membrane 14, ensuring the installation stability of these components and preventing loosening or displacement due to the movement of the movable structure 2 or other external forces, thereby ensuring the normal operating performance of the support assembly 100.

[0088] According to some embodiments of this utility model, refer to Figure 2 The support base 3 also includes an inner shell 33 and a buffer member 34. The inner shell 33 is located on the inner circumference of the support base 3. A first through hole 35 is formed on the support base 3, and a second through hole 331 is formed on the inner shell 33. The second through hole 331 and the first through hole 35 are opposite to each other along the axial direction of the support base 3. The piston rod 3022 of the shock absorber 302 is adapted to be fitted at the second through hole 331 to be connected to the support base 3. The inner wall surface of the support base 3 and the inner shell 33 together define the receiving space. The buffer member 34 is disposed in the receiving space. The second support part 32 is connected to the upper air chamber of the air spring 303 of the suspension system 300.

[0089] Therefore, when the suspension system 300 encounters harsh conditions, such as bumpy roads or violent vehicle movement, when the piston rod 3022 of the shock absorber 302 drives the inner housing 33 to move, the buffer 34 can absorb the impact force from the swing of the shock absorber 302 through deformation, thereby reducing the force ultimately transmitted from the shock absorber 302 to the vehicle body 401, thus improving the stability of the vehicle body 401 and the stability of vehicle driving. By setting the movable structure 2, the overall oscillation of the piston rod 3022, support seat 3, mounting bracket 1, and air spring 303 is achieved. There is no relative movement between the support seat 3 and the piston rod 3022, which can reduce the wear of the buffer 34 during the movement of the piston rod 3022, extend the service life of the support seat 3, and effectively solve the problems of accelerated wear of the buffer 34, material fatigue, and abnormal noise in the overall structure. Moreover, it can also reduce the stress at the air spring 303, thereby reducing the wear of the air spring 303 and extending its service life.

[0090] According to the second aspect embodiment of the present utility model, the support assembly 200, with reference to... Figure 4 and Figure 6 The system includes a support assembly 100 and a body seat 4. Specifically, the support assembly 100 is a support assembly 100 for a suspension system 300 according to the first aspect embodiment described above. The body seat 4 is connected to the movable structure 2 of the support assembly 100.

[0091] According to the embodiment of this utility model, the support assembly 200, by employing the aforementioned support assembly 100, can improve the lateral clamping force of the support assembly 200, eliminate the lateral movement of the support assembly 200 relative to the air spring 303 after being subjected to lateral impact, and reduce the wear of the movable structure 2, thereby effectively extending the service life of the support assembly 200 and improving its working stability. Furthermore, the support assembly 200, composed of the support assembly 100 and the vehicle body seat 4, has the advantages of optimizing the yaw stiffness of the support assembly 100, the shock absorber 302, and the air spring 303, decoupling the internal lateral forces between the mounting bracket 1 and the shock absorber 302 and the air spring 303, and having high structural strength. This reduces the wear of the movable structure 2, extending the service life and working stability of the suspension system 300. Moreover, it can reduce the abnormal noise of the shock absorber 302, improving the user experience. In addition, the support assembly 200 has a simple structure, which helps to reduce the difficulty of processing and installation.

[0092] According to some other embodiments of this utility model, the support assembly 200 can be used in conjunction with various types of vibration dampers 302, such as twin-tube vibration dampers and electromagnetic vibration dampers (not shown in the figure). It should be noted that the size of the support assembly 200 and its assembly with twin-tube vibration dampers, electromagnetic vibration dampers, etc., can be flexibly designed according to actual conditions, and no specific limitations are made here.

[0093] According to some embodiments of this utility model, refer to Figure 6 The vehicle body seat 4 includes a first vehicle body seat 41 and a second vehicle body seat 42. Specifically, the first vehicle body seat 41 includes two side plates 411 facing each other, a movable structure 2 is located between the two side plates 411, and a connecting structure 44 connects the two side plates 411 and the movable structure 2. The second vehicle body seat 42 is connected to the first vehicle body seat 41, and the second vehicle body seat 42 includes a plurality of vehicle body connecting legs 421.

[0094] For example, in Figure 6 In the example, the first body seat 41 is located on the side of the second body seat 42 away from the shock absorber 302. Furthermore, the first body seat 41 consists of two opposing side plates 411, defining the installation space for the movable structure 2, and is approximately U-shaped. This facilitates the installation and positioning of the movable structure 2, effectively reducing the installation difficulty. In addition, the first body seat 41 can limit the movement of the movable structure 2 along its own axis, thus stably confining the movable structure 2 within the space defined by the first body seat 41, making the connection between the mounting bracket 1 and the body seat 4 more secure. Furthermore, the two side plates 411 of the first body seat 41 can provide some protection for the movable structure 2, preventing it from being affected and damaged by the external environment.

[0095] Furthermore, the body seat 4 and the support assembly 100 are connected by a spherical joint (i.e., the body seat 4 and the support assembly 100 move relative to each other on a spherical surface). When the vehicle encounters bumps or turns, the shock absorber 302 swings, which can drive the mounting bracket 1 to swing relative to the body seat 4 through cooperation with the movable structure 2. This allows the shock absorber 302 to drive the air spring 303 of the suspension system 300 and the mounting bracket 1 to swing relative to the body 401. This reduces the stiffness of the air spring 303 and the support assembly 200, maintaining coaxial movement with the shock absorber 302, thereby mitigating the adverse effects of sway, improving the damping effect, reducing steering noise or vibration, and thus improving driving safety and comfort.

[0096] For example, refer to Figure 6The vehicle body connecting feet 421 are provided in three shapes, exhibiting a claw-shaped structure similar to the mounting feet 12. This improves the connection stability between the vehicle body seat 4 and the vehicle body 401, effectively reducing the swaying and displacement of the vehicle body seat 4 during vehicle operation, thus enhancing the stability and safety of the vehicle body 401. Furthermore, the claw-shaped second vehicle body seat 42 utilizes space more effectively while meeting support requirements, reducing installation difficulty and improving installation efficiency. Moreover, compared to other multi-claw structures, it reduces the amount of production materials used, thereby reducing the weight of the vehicle body 401, lowering production costs, and contributing to improved fuel economy or driving range.

[0097] According to some optional embodiments of the present invention, refer to Figure 4 The two side plates 411 are respectively formed with mounting holes 43. The connecting structure 44 includes a rotating shaft 441, which is inserted through the movable structure 2. Both ends of the rotating shaft 441 extend through the mounting holes 43 to the outside of the body seat 4. Nuts 442 are threaded to both ends of the rotating shaft 441.

[0098] For example, in Figure 4 In the example, each of the two side plates 411 has a mounting hole 43, which are corresponding in position and shape. The two ends of the rotating shaft 441 pass through the mounting holes 43 on the two side plates 411 and extend to the outside of the body seat 4. The rotating shaft 441 and the body seat 4 are threaded together by a nut 442. For example, the shape of the mounting hole 43 can be round, elliptical, square, etc., but is not limited to these. Thus, the mounting hole 43 provides a mounting position for the connection between the body seat 4 and the support assembly 100, thereby reducing the installation difficulty of the body seat 4 and the support assembly 100. Furthermore, it improves the installation stability of the body seat 4 and the support assembly 100, making the connection between the mounting bracket 1 and the body seat 4 more stable, which is beneficial for the long-term use of the support assembly connection assembly 200. In addition, the above connection method is relatively simple, facilitating the inspection, lubrication, and replacement of the moving structure 2 and its related components during vehicle maintenance and upkeep. Moreover, when the movable structure 2 is worn or damaged, it can be simply removed from the vehicle body seat 4 and replaced with a new movable structure 2. The operation is simple and convenient, effectively reducing the vehicle's maintenance costs and time.

[0099] According to some embodiments of this utility model, refer to Figure 4 Multiple body-mounted connecting feet 421 are staggered from the multiple mounting feet 12 of the support assembly 100. For example, in Figure 4 In the example, multiple body connecting legs 421 and multiple mounting legs 12 are arranged in a staggered pattern along the circumference of the movable structure 2.

[0100] This arrangement, with its staggered arrangement of the body connecting feet 421 and mounting feet 12, effectively utilizes space, making the connection between the support assembly 100 and the body seat 4 more compact and freeing up more space for other components, which is beneficial to the overall layout and design of the vehicle. Furthermore, the staggered arrangement increases the number and uniformity of the connection points, making the connection between the support assembly 100 and the body 401 more stable. During vehicle operation, especially when encountering complex road conditions or severe vibrations, it can better maintain the correct posture and position of the suspension system 300, reducing problems such as loosening and deformation of suspension components due to unstable connections, thus improving the vehicle's driving stability and safety. Furthermore, the staggered arrangement of the body connecting feet 421 and mounting feet 12 allows the suspension system 300 to more evenly transmit and distribute forces to the support assembly 200 when subjected to various forces during vehicle operation. This effectively avoids stress concentration, thereby reducing the stress on local structures of the support assembly 200, reducing the risk of component damage, improving the overall durability of the support assembly 200, and extending its service life. Additionally, the rational staggered arrangement of the body connecting feet 421 and mounting feet 12 helps reduce the difficulty of installing the support assembly 100 to the body seat 4, improving installation efficiency.

[0101] According to a third aspect embodiment of the present invention, a suspension system 300 is provided, referring to... Figure 4 This includes a support assembly 100 for a suspension system 300 according to the first aspect embodiment described above, or a support assembly connection assembly 200 according to the second aspect embodiment described above.

[0102] According to an embodiment of the present invention, the suspension system 300, by employing the aforementioned support assembly 200, enhances the buffering effect of the suspension system 300 and improves the stability of the vehicle body 401. Furthermore, during the rotation of the rear wheels, the support assembly 100 can rotate axially around the movable structure 2, reducing the rotational stiffness of the support assembly 100 and improving the comfort of the suspension system 300. Simultaneously, it improves the sealing and buffering performance of the air spring 303, enhancing the stability and reliability of the suspension system 300.

[0103] According to some optional embodiments of the present invention, refer to Figure 4 The suspension system 300 also includes a shock absorber 302 and an air spring 303. One end of the piston rod 3022 of the shock absorber 302 is connected to the support seat 3. The air spring bladder 3031 of the air spring 303 is sleeved on the outside of the cylinder 3021 of the shock absorber 302, and the upper air chamber of the air spring 303 is connected to the second support part 32 of the support seat 3.

[0104] Therefore, when the vehicle encounters bumps or turns, the shock absorber 302 swings, which in turn drives the support seat 3 to swing. Through the movable structure 2 and the mounting bracket 1, the shock absorber 302, along with the air spring 303 and the mounting bracket 1, can swing relative to the vehicle body 401. There is no relative movement between the air spring bladder 3031 and the shock absorber 302, reducing friction between them. This ensures the shock absorber 302's damping effect while resolving localized stress concentration in the air spring bladder 3031, which could lead to material fatigue or damage. It also improves the sealing of the air spring 303 and the cushioning performance of the shock absorber 302. Furthermore, the swinging of the movable structure 2 adapts to changes in force, avoiding excessive friction, tension, and stress concentration between components caused by rigid connections. This effectively reduces wear on components of the suspension system 300, such as the support assembly 100 and suspension arms, extending the service life of the support assembly 100 and other components in the suspension system 300, and reducing vehicle maintenance costs.

[0105] Optionally, the support assembly 100 can be used with a MacPherson strut suspension system (not shown in the figure) to effectively eliminate the lateral force of the shock absorber 302, eliminating the need for eccentric arrangement of the coil spring and thus extending the service life of the coil spring. In other words, the support assembly 100 can be applied to different types of suspension systems 300 to facilitate the long-term use of the air spring 303 or coil spring, etc., in the suspension system 300.

[0106] A vehicle (not shown) according to a fourth aspect embodiment of the present invention includes a support assembly 100 for a suspension system 300 according to the first aspect embodiment, or a support assembly connection assembly 200 according to the second aspect embodiment, or a suspension system 300 according to the third aspect embodiment.

[0107] According to the vehicle embodiment of this utility model, the support assembly 100 and the vehicle body 401 are connected by a spherical joint (i.e., there is no relative movement between the shock absorber 302, the air spring 303, and the mounting bracket 1; the mounting bracket 1 can move relative to the vehicle body 401 along the spherical surface of the movable structure 2, so that the mounting bracket 1 and other structures can move relative to the vehicle body 401). When the piston rod 3022 of the shock absorber 302 wobbles, the mounting bracket 1 wobbles synchronously with the shock absorber 302 and the air spring 303. The internal lateral force between the three can be effectively reduced or even eliminated, effectively reducing abnormal noise and reducing wear between the internal components of the air spring 303, thereby extending the service life of the support assembly 200 and improving vehicle driving safety and comfort.

[0108] The support assembly 100 for the suspension system 300, the support assembly connection assembly 200, the suspension system 300, the vehicle, and the operation according to the embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
