[0030] The embodiments of the present invention will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1-7 Describe the support combination assembly 100 according to the first - aspect embodiment of the present invention. The support combination assembly 100 can be used in the suspension system 200 of the vehicle 300, but is not limited thereto. In the following description of the present application, the support combination assembly 100 is described by taking the suspension system 200 of the vehicle 300 as an example.

[0031] As Figure 1 and Figure 3 , the support combination assembly 100 according to the first - aspect embodiment of the present invention includes a support base 1, a buffer member 2, and a movable structure 3.

[0032] Specifically, the buffer member 2 is connected to the support base 1, the movable structure 3 is arranged on the side of the buffer member 2 close to the support combination assembly 100, the movable structure 3 is adapted to be connected to the shock absorber 201 of the suspension system 200, and the movable structure 3 is adapted to be actuated by the shock absorber 201 to be movable relative to the buffer member 2.

[0033] For example, in Figure 1 andFigure 3 In the example, the buffer member 2 is connected to the inner peripheral side of the support base 1, and one end of the buffer member 2 away from the movable structure 3 cooperates with the movable structure 3. Combining Figure 7 , the upper end of the piston rod 2012 of the shock absorber 201 passes through the support assembly 100 to cooperate with the support assembly 100. The movable structure 3 contacts the piston rod 2012, and the movable structure 3 is located between the buffer member 2 and the piston rod 2012.

[0034] Taking the air suspension as an example, in the traditional technology, the air suspension is rigidly connected to the vehicle body through the upper support assembly. When the air suspension of the vehicle encounters harsh working conditions (such as road surface bumps or violent vehicle movements), the shock absorber of the air suspension yaws relative to the vehicle, which will cause the air spring (such as the bladder) outside the shock absorber to also yaw accordingly, resulting in additional movement interference between the shock absorber and the air spring and forming a lateral force. At the same time, the air spring deforms due to tilting, resulting in unequal volumes of the two relatively halves inside the air spring, which generates a lateral force on the shock absorber. And the piston rod of the shock absorber is also subjected to a lateral force, and these lateral forces affect the use of the air suspension.

[0035] In the present application, when the piston rod 2012 of the shock absorber 201 moves up and down and yaws in the direction away from the central axis of the piston rod 2012, the piston rod 2012 drives the movable structure 3 to yaw synchronously, so that the movable structure 3 yaws in the same direction. The movable structure 3 moves relative to the buffer member 2, and the movable structure 3 squeezes the upper or lower part of the buffer member 2 to deform and compress, releases the yaw energy, decouples the lateral force generated by the yaw movement, decouples the axial stiffness and the yaw stiffness, reduces the yaw stiffness, and can effectively reduce the lateral deviation abnormal noise, jamming, etc. generated when the shock absorber 201 moves, improves the noise, vibration and harshness (NVH) of the suspension system 200, and also improves the stability and reliability of the suspension system 200 in use and the comfort of the occupants. In addition, the stress concentration on the elastic component 202 in the suspension system 200 is also reduced, thereby avoiding fatigue damage of the elastic component 202 and prolonging the service life of the suspension system 200. In addition, the structural design of the support assembly 100 is simple, the cost is low, and it does not occupy the layout space of the suspension system 200, which is convenient for the installation of the suspension system 200. Moreover, the buffer member 2 is formed by vulcanizing a rubber part, has high strength, light weight and excellent durability, and mainly performs the functions of shock absorption, buffering and energy absorption, and can be deformed to extend and compress up and down.

[0036] The support assembly 100 for a suspension system 200 according to the present invention has a movable structure 3 that moves relative to a buffer member 2 along with a piston rod 2012, so as to squeeze the upper or lower part of the buffer member 2 to cause compressive deformation, decouple the lateral force generated by yaw motion, decouple the axial stiffness and yaw stiffness, reduce the yaw stiffness, alleviate side slip abnormal noise, jamming, etc., improve the sound vibration roughness, and also improve the stability and reliability of the suspension system 200 during use, and improve the comfort of the occupants. In addition, the service life of the suspension system 200 is also extended. Moreover, the support assembly 100 has a simple structural design, low cost, and does not occupy the layout space of the suspension system 200, facilitating the installation of the suspension system 200.

[0037] According to some embodiments of the present invention, referring to Figure 3 , the support assembly 100 further includes a buffer skeleton 4, the buffer skeleton 4 is completely covered inside the buffer member 2, and the hardness of the buffer skeleton 4 is greater than that of the buffer member 2; When the movable structure 3 is actuated by the shock absorber 201 to move, at least part of the buffer member 2 is deformable under the action of the movable structure 3; or When the movable structure 3 is actuated by the shock absorber 201 to move, at least part of the buffer member 2 is deformable under the action of the movable structure 3, and at least part of the buffer skeleton 4 is movable under the action of the movable structure 3.

[0038] For example, in the Figure 3 example, the buffer member 2 is sleeved on the outer peripheral side of the buffer skeleton 4, and the buffer member 2 is located between the buffer skeleton 4 and the movable structure 3. When the yaw angle of the shock absorber 201 is relatively small, the movable structure 3 is actuated by the shock absorber 201 to yaw at a small angle, the movable structure 3 moves relative to the buffer member 2, and the movable structure 3 squeezes a part of the buffer member 2 close to the center of the support assembly 100, and a part of the buffer member 2 close to the center of the support assembly 100 is deformed to release energy, achieving the first-stage decoupling of the yaw motion (as shown in Figure 6 ). When the yaw angle of the shock absorber 201 is relatively large, the yaw angle of the movable structure 3 actuated by the shock absorber 201 gradually increases, the movable structure 3 moves relative to the buffer member 2, the movable structure 3 first squeezes a part of the buffer member 2 close to the center of the support assembly 100, and the above-mentioned part of the buffer member 2 is first deformed to release energy, achieving the first-stage decoupling of the yaw motion (as shown in Figure 6 ). As the yaw angle continues to increase, the degree of movement of the movable structure 3 relative to the buffer member 2 increases, the action of the movable structure 3 on the buffer member 2 increases, another part of the buffer member 2 away from the center of the support assembly 100 is also deformed, and a part of the buffer skeleton 4 close to the center of the support assembly 100 moves, and the buffer member 2 and the buffer skeleton 4 move together with the movable structure 3 to yaw, further releasing energy, achieving the second-stage decoupling of the yaw motion (as shown inFigure 7 as shown

[0039] With such an arrangement, the buffer frame 4 has a relatively high hardness. The buffer frame 4 supports the buffer member 2, preventing the buffer member 2 from being excessively deformed during the movement of the movable structure 3, reducing the fatigue of the buffer member 2 during use, and thus facilitating the long-term normal use of the buffer member 2. In addition, the buffer frame 4 supports the buffer member 2, improving the cooperation strength between the buffer member 2 and the movable structure 3, thereby enhancing the stability of the cooperation between the buffer member 2 and the movable structure 3 and extending the service life of the support assembly 100. Additionally, when the shock absorber 201 yaws, the movable structure 3, the buffer member 2, and the buffer frame 4 cooperate with each other, and different degrees of decoupling can be achieved according to the magnitude of the yaw angle of the shock absorber 201, effectively ensuring the release of energy, reducing or eliminating the lateral force, improving the stability and reliability of the suspension system 200 during use, and also enhancing the flexibility of the support assembly 100 during use to flexibly cope with different road conditions.

[0040] Furthermore, referring to Figure 7 , at least a part of the buffer frame 4 is movable along the axial direction of the support seat 1 under the action of the movable structure 3. For example, in the example of FIG. 7, when the movable structure 3 is actuated by the shock absorber 201 to move, at least a part of the buffer member 2 is deformable under the action of the movable structure 3, and at least a part of the buffer frame 4 is movable under the action of the movable structure 3. A part of the buffer frame 4 close to the support assembly 100 moves downward along the axial direction of the support seat 1 under the action of the movable structure 3. Compared with the prior art, when the shock absorber yaws, the liner of the upper support assembly of the air suspension is deformed under the action of the piston rod of the shock absorber, in the present application, when the yaw angle of the shock absorber 201 is relatively small, the movable structure 3 moves downward along the axial direction of the support seat 1 relative to the buffer member 2, a part of the buffer member 2 close to the center of the support assembly 100 is deformed, and the buffer frame 4 does not move relative to the support seat 1 (as shown in Figure 6 ). When the yaw angle of the shock absorber 201 continues to increase, the movable structure 3 continues to move downward relative to the buffer member 2, and another part of the buffer member 2 far from the center of the support assembly 100 is also deformed under the action of the movable structure 3. Both the buffer member 2 and the buffer frame 4 move relative to the support seat 1, and the buffer member 2 and the buffer frame 4 move downward together under the action of the movable structure 3 (as shown in Figure 7 ), thereby achieving the two-stage decoupling of the suspension system 200, improving the decoupling effect on the lateral force of the suspension system 200, and further enhancing the stability and reliability of the suspension system 200 during use.

[0041] According to some embodiments of the present invention, referring to Figure 3, a mating groove 31 is formed on a side surface of the movable structure 3 facing the support base 1, a mating portion 21 is provided on the buffer member 2, and the mating portion 21 is movably fitted in the mating groove 31.

[0042] For example, in Figure 3 In the example of, the mating groove 31 is formed on the outer peripheral side surface of the movable structure 3 (i.e., a side surface of the movable structure 3 facing the support base 1), and the mating portion 21 is connected to the inner peripheral side surface of the buffer member 2 (i.e., a side surface of the buffer member 2 facing the movable structure 3). When the piston rod 2012 of the shock absorber 201 moves, the movable structure 3 moves, and the side wall of the mating groove 31 presses against the mating portion 21, and the mating portion 21 is compressed and deformed. With such a setting, the arrangement of the mating portion 21 and the mating groove 31 simplifies the assembly method of the movable structure 3 and the buffer member 2, thereby improving the assembly efficiency of the movable structure 3 and the buffer member 2. In addition, by the side wall of the mating groove 31 pressing against the mating portion 21, it is also easy to realize the movement of the movable structure 3 and easy to achieve decoupling, thereby improving the use performance of the support assembly 100. In addition, the side wall of the mating groove 31 supports the mating portion 21 for limiting, improving the stability.

[0043] According to some embodiments of the present invention, Figure 3 and Figure 4 , a hemming 211 is provided on one side of the mating portion 21 along the axial direction of the support base 1, the free end of the hemming 211 extends in a direction away from the central axis of the support base 1, and there is a gap between the hemming 211 and the mating portion 21.

[0044] For example, in Figure 3 and Figure 4 In the example of, the hemming 211 is connected to a side surface of the mating portion 21 close to the central axis of the support base 1, the hemming 211 first extends in an upward direction and then extends in a direction away from the central axis of the support base 1, the hemming 211 can be located on the upper side of the mating portion 21, there is a gap between the hemming 211 and the mating portion 21 in the up and down direction, and the shapes of the outer side surface of the hemming 211 and the outer side surface of the mating portion 21 are adapted to the shape of the side wall surface of the mating groove 31. With such a setting, during the movement of the movable structure 3, the gap between the hemming 211 and the mating portion 21 increases the movement space of the movable structure 3, that is, increases the yaw space, which is beneficial to improving the decoupling effect, further reducing the yaw stiffness, improving the use performance of the support assembly 100, and further reducing abnormal noise and improving the comfort. However, it is not limited to this, the hemming 211 can also be located on the lower side of the mating portion 21, and the position of the hemming 211 can be specifically set according to the actual use situation to meet the actual requirements.

[0045] According to some embodiments of the present invention, referring to Figure 3 and Figure 4, one side of the buffer frame 4 facing the movable structure 3 has an extension 41, and the extension 41 extends into the mating groove 31.

[0046] For example, in Figure 3 and Figure 4 In the schematic example of, the mating part 21 is sleeved outside the extension 41, and after the extension 41 is mated with the mating part 21, they extend into the mating groove 31 together. With such a setting, the extension 41 supports the mating part 21, enabling the mating part 21 to be closely fitted in the mating groove 31, further improving the mating stability between the buffer member 2 and the movable structure 3, and also further improving the stability of the mating between the buffer frame 4 and the movable structure 3, thereby further improving the stability of the use of the support assembly 100, enabling the support assembly 100 to be used normally for a long time.

[0047] Furthermore, referring to Figure 4 , the free end face of the extension 41 is located on the side closer to the central axis of the support base 1 than the free end face of the folded edge 211.

[0048] For example, in Figure 4 In the example of, the free end face of the extension 41 is the C surface, and the free end face of the folded edge 211 is the D surface, that is, the C surface is located on the side closer to the central axis of the support base 1 than the D surface. That is to say, the B surface is located on the right side of the C surface, and at least a part (such as the right part) of the extension 41 overlaps with the mating groove 31 in the radial direction of the support assembly 100 (such as the left - right direction in Figure 4 ). With such a setting, when the degree of yaw of the movable structure 3 is relatively large and the buffer frame 4 yaws together, it ensures a stable relative position relationship between the buffer frame 4 and the movable structure 3 without movement separation, further preventing the movable structure 3 from detaching from the buffer member 2 and the buffer frame 4, and further improving the stability of use. In addition, the stiffness of the movable structure 3 and the buffer frame 4 is greater than the stiffness of the buffer member 2, and the mating groove 31 wraps the extension 41, improving the supporting effect on the mating part 21 of the buffer member 2. Thus, during the repeated torsion of the buffer member 2, the mating part 21 is prevented from breaking, and further extends the service life of the buffer member 2. Among them, the free end face of the folded edge 211 and the free end face of the movable structure 3 on the upper side of the mating groove 31 are in the same plane in the up - down direction, but it is not limited to this.

[0049] According to some embodiments of the present invention, referring to Figure 3 , a through - hole 11 is formed on the support base 1, the buffer member 2 and the movable structure 3 are respectively arranged at the through - hole 11, one side of the buffer member 2 is fixed to the inner wall surface of the through - hole 11, and the other side of the buffer member 2 is movably mated with the movable structure 3.

[0050] For example, in Figure 3In the example, the buffer member 2 is located between the inner wall surface of the through hole 11 and the movable structure 3. With such an arrangement, it is convenient to mount the buffer block 206 and the movable structure 3 on the support base 1, improving the mounting efficiency of the buffer block 206 and the movable structure 3 on the support base 1, and thus improving the mounting efficiency of the support assembly 100. Among them, a bushing 6 is provided between the buffer block 206 and the inner wall surface of the through hole 11. The bushing 6 is in close contact with the inner wall surface of the through hole 11, and one side of the buffer block 206 away from the central axis of the support base 1 is in close contact with the bushing 6, thereby further improving the mounting stability of the buffer block 206 and the support base 1.

[0051] According to some embodiments of the present invention, referring to Figures 5-7 , the initial thickness of the deformation region of the buffer member 2 is L0, and the thickness change amount of the deformation region after being extruded is ΔL. Among them, L0 and ΔL satisfy: 0 < ΔL / L0 ≤ 3 / 4.

[0052] For example, in the Figures 5-7 example, when the piston rod 2012 of the shock absorber 201 jumps upward, at this time the yaw angle of the shock absorber 201 is relatively small, and the deformation region of the buffer member 2 is the mating portion 21 between the lower side surface of the extension portion 41 and the side wall of the mating groove 31. The initial thickness L0 of the deformation region of the buffer member 2 is Figure 5 L1 shown in Figure 5 . When the piston rod 2012 of the shock absorber 201 continues to jump upward, at this time the yaw of the shock absorber 201 is relatively large, and the deformation region of the buffer member 2 is the mating portion 21 between the upper side surface of the buffer skeleton 4 and the side wall surface of the through hole 11. The initial thickness L0 of the deformation region of the buffer member 2 is L2 shown in

[0053] . The thickness change amount ΔL of the deformation region after being extruded satisfies: 0 < ΔL ≤ Figure 5 Figure 5 . When the piston rod 2012 of the shock absorber 201 jumps downward, at this time the yaw angle of the shock absorber 201 is relatively small, and the deformation region of the buffer member 2 is the mating portion 21 between the upper side surface of the extension portion 41 and the side wall of the mating groove 31, the hem 211, and the gap between the mating portion 21 and the hem 211. The initial thickness L0 of the deformation region of the buffer member 2 is L4 shown in

[0054] ​With such a setting, according to the magnitude of the yaw angle, decoupling is achieved with different compression degrees to cope with different situations, thereby improving the flexibility of use of the support combination assembly 100 and also improving the performance of use of the support combination assembly 100, effectively reducing the yaw stiffness. Among them, during the process of the buffer member 2 being deformed and compressed, the thickness of the buffer member 2 continuously decreases. Among them, the thickness of the buffer member 2 can be appropriately selected according to the stiffness of the buffer member 2.

[0055] According to some embodiments of the present invention, referring to Figure 5 , the distance in the axial direction of the support seat 1 between one side surface of the movable structure 3 along the axial direction of the support seat 1 and the inner wall surface of the corresponding through hole 11 is H, where ΔL and H satisfy: ΔL ≤ H.

[0056] For example, in the example of Figure 5 , the distance between the upper side surface of the movable structure 3 and the corresponding inner wall surface of the through hole 11 is H along the up and down reverse direction. When the piston rod 2012 of the shock absorber 201 jumps upward, ΔL and H satisfy: ΔL ≤ H, that is ≤ H. With such a setting, when the piston rod 2012 of the shock absorber 201 jumps upward, during the movement of the movable structure 3, it further avoids the separation of the buffer skeleton 4 and the buffer member 2 from the movable structure 3 or the support seat 1, improving the coordination and stability of the support combination assembly 100 during the yaw movement process. It should be noted that H is preferably less than or equal to the moving distance of the piston rod 2012 of the shock absorber 201 in the axial direction of the support seat 1.

[0057] According to some embodiments of the present invention, referring to Figure 5 and Figure 8 , the movable structure 3 is adapted to be respectively connected to the elastic component 202 and the shock absorber 201 of the suspension system 200, and ΔL is adapted to be less than or equal to the moving distance of the piston rod 2012 of the shock absorber 201 in the axial direction of the support seat 1.

[0058] For example, in the examples of Figure 5 and Figure 8 , the piston rod 2012 of the shock absorber 201 cooperates with the movable structure 3, and the elastic component 202 is connected to the movable structure 3. When the piston rod 2012 of the shock absorber 201 jumps downward, ΔL is adapted to be less than or equal to the moving distance of the piston rod 2012 of the shock absorber 201 in the up and down direction, that is It is suitable for the movement distance of the piston rod 2012 of the shock absorber 201 in the up and down direction less than or equal to this value. With such a setting, when the piston rod 2012 of the shock absorber 201 jumps downward, during the movement of the movable structure 3, it further avoids the separation of the buffer skeleton 4 and the buffer member 2 from the movable structure 3 or the support seat 1, and improves the coordination and stability of the support assembly 100 during the yaw movement. It should be noted that the movement distance of the piston rod 2012 of the shock absorber 201 in the up and down direction is the minimum clearance between the lower end of the cylinder block 2011 of the shock absorber 201 and other peripheral components (such as the transmission shaft).

[0059] According to some embodiments of the present invention, referring to Figure 3 , the support seat 1 includes a first support seat 12 and a second support seat 13.

[0060] Specifically, a first through-hole section 121 is formed on the first support seat 12, the buffer member 2 is provided at the first through-hole section 121, and a clamping groove 1211 is formed on the inner wall surface of the first through-hole section 121. A second through-hole section 131 is formed on the second support seat 13, and the second through-hole section 131 and the first through-hole section 121 together form a through-hole 11, and a part of the second support seat 13 is fitted in the clamping groove 1211.

[0061] For example, in the example of Figure 3 , the buffer member 2 and the movable structure 3 are provided at the first through-hole section 121. The clamping groove 1211 is formed at the lower end of the first through-hole section 121, and one end of the second support seat 13 facing the first support seat 12 is fitted in the clamping groove 1211. The buffer member 2 and the movable structure 3 are located above the second support seat 13. With such a setting, the upper side surface of the second support seat 13 (such as the E surface in Figure 5 ) is the lower limit position for the movement of the buffer member 2, and the side wall surface of the first through-hole section 121 (such as the F surface in Figure 5 ) is the upper limit position for the movement of the buffer member 2, so as to determine that the movement range of the buffer member 2 in the axial direction of the support seat 1 is controllable, prevent the buffer member 2 from being overly deformed, thereby reducing the fatigue degree of the buffer member 2 and prolonging the service life. In addition, the first through-hole section 121 provides an installation position and a movement space for the buffer member 2, the buffer skeleton 4 and the movable structure 3 for installation and movement. Among them, the support seat 1, as the main support structure of the support assembly 100, has high strength and is designed with lightweight at the same time. An installation hole 122 is formed at one end of the first support seat 12 far from the central axis of the support seat 1, and the support assembly 100 further includes a fastener 5 (such as a bolt), and the fastener 5 passes through the installation hole 122 and is fixedly connected to the vehicle body 301 of the vehicle 300.

[0062] According to some embodiments of the present invention, referring to Figure 5, the inner wall surface of the second through-hole section 131 is located between the connection point of the side surface of the buffer framework 4 facing the second support seat 13 and the side surface of the buffer framework 4 facing the movable structure 3 and the side surface of the movable structure 3 facing the first support seat 12.

[0063] For example, in Figure 5 example, the inner wall surface of the second through-hole section 131 is the G surface, the connection point between the lower side surface of the buffer framework 4 and the side surface of the buffer framework 4 facing the movable structure 3 is the I point, and the side surface of the lower end of the movable structure 3 facing the first support seat 12 is the J surface. The G surface is located between the I point and the J surface. The connection point between the side surface of the lower end of the movable structure 3 facing the first support seat 12 and the lower side surface of the movable structure 3 is the K point, that is, the G surface is located between the I point and the K point. With such a setting, the movement range of the buffer framework 4 is further limited, avoiding excessive deviation of the buffer framework 4 towards the center of the support seat 1 and improving the use stability of the buffer framework 4. In addition, it effectively ensures that the K point does not interfere with the second support seat 13 when moving downward, enabling the normal movement of the movable structure 3. Among them, the side of the bushing 6 facing the central axis of the support seat 1 is the outer limit of the buffer member 2, and the bottom wall of the fitting groove 31 is the inner limit of the buffer member 2. The upper wall surface of the first through-hole section 121 (such as Figure 5 the Q surface in Figure 5 ) is the upper limit of the movement of the buffer member 2, and the upper side surface of the second support seat 13 (such as Figure 5 the S surface in Figure 5 ) is the lower limit of the movement of the buffer member 2. The upper wall surface of the fitting groove 31 (such as Figure 5 the N surface in Figure 5 ) is the secondary upper limit of the movement of the buffer member 2, and the upper wall surface of the fitting groove 31 (such as Figure 5 the P surface in Figure 5 ) is the secondary lower limit of the movement of the buffer member 2, further enhancing the movement control of the buffer member 2 during the yaw process and ensuring the stability of the buffer member 2 under different working conditions.

[0064] For example, taking the left yaw of the piston rod 2012 as an example, Figure 5 is the initial state. At this time, the support assembly 100 is assembled with the piston rod 2012, and the piston rod 2012 applies a preloading force to the movable structure 3. The upper end surface of the buffer member 2 is in contact with the movement upper limit Q surface. Through the synchronous yaw of the piston rod 2012 driving the movable structure 3, the buffer member 2 is driven to perform a left yaw movement. First, as Figure 6 shown, the movable structure 3 yaws, thus realizing the first-stage decoupling of the yaw movement. Among them, the assembly relationship between the movable structure 3 and the buffer member 2 not only ensures the transmission of the yaw movement but also ensures that the two do not separate relatively. At the same time, the reserved movement space between the two (i.e., the gap between the folded edge 211 and the fitting portion 21) makes the yaw angle not too small.

[0065] Next, as Figure 7As shown, as the yaw angle gradually increases, the buffer member 2 and the buffer frame 4 undergo yaw. The yaw movement of the buffer member 2 causes the upper end of the buffer member 2 to leave the upper limit Q surface of the axial movement, move downward and be compressed to the lower limit S surface of the axial movement. At the same time, the buffer member 2 deforms, further flexibly releasing the yaw movement to achieve the second-stage decoupling of the yaw movement. Among them, during the deformation of the buffer member 2, the thickness of the buffer member 2 gradually decreases. Thus, during the first-stage decoupling, the yaw movement realizes preliminary decoupling through the gap reserved between the engaging portion 21 and the flanging 211, reducing the yaw stiffness. During the second-stage decoupling, the deformation and compression of the buffer member 2 further release the yaw energy, further reducing the yaw stiffness, and significantly improving the comfort of the suspension system 200. Among them, as the yaw angle gradually increases, the gap between the flanging 211 and the engaging portion 21 gradually decreases. However, it is not limited to this. It should be noted that during the first-stage decoupling, according to the actual use situation, the preliminary decoupling can be achieved by reducing the reserved gap and at least partial deformation of the buffer member 2.

[0066] According to some embodiments of the present invention, referring to Figure 1 and Figure 2 , a mating hole 32 is formed on the movable structure 3, and at least one limiting groove 321 is formed on the inner wall surface of the mating hole 32.

[0067] For example, in the examples of Figure 1 and Figure 2 , the mating hole 32 penetrates the movable structure 3 along the thickness direction of the movable structure 3. Combining Figure 8 , the piston rod 2012 of the shock absorber 201 passes through the mating hole 32, and other components on the piston rod 2012 are fitted in the limiting groove 321. The limiting groove 321 limits the piston rod 2012 to prevent the piston rod 2012 from rotating relative to the support assembly 100, thereby improving the assembly stability of the movable rod and the support assembly 100 and the use stability of the suspension system 200. However, it is not limited to this. A plurality of limiting grooves 321 can be provided, and the plurality of limiting grooves 321 are arranged at intervals along the circumferential direction of the movable structure 3 (such as equally spaced or non-equally spaced). It should be noted that the number and arrangement manner of the limiting grooves 321 can be specifically set according to the actual use situation to meet the actual requirements. In the description of the present invention, "a plurality" means two or more.

[0068] According to some embodiments of the present invention, referring to Figure 3 and Figure 4 , a groove 22 is formed on the side surface of the buffer member 2 close to the shock absorber 201 along the axial direction of the support seat 1, and the groove 22 is located on the side of the movable structure 3 away from the center of the support assembly 100. For example, in Figure 3 and Figure 4In the example, the groove 22 is formed on the lower side surface of the buffer member 2, and the groove 22 is recessed upward. With such a setting, when the second-stage decoupling of the yaw movement of the support assembly 100 occurs, the groove 22 provides space for further deformation of the buffer member 2, increases the movement space of the movable structure 3, further increases the yaw angle of the movable structure 3, which is beneficial to effectively release energy, further reduces the lateral force, further improves the comfort of the occupant, and further extends the service life of the suspension system 200.

[0069] Optionally, referring to Figure 3 and Figure 5 , a stepped surface is provided on one side surface of the movable structure 3 along the axial direction of the support base 1. For example, in Figure 3 and Figure 8 's example, the stepped surface is formed at the lower side surface of the movable structure 3. With such a setting, when the support assembly 100 is used for the suspension system 200, it is convenient for the movable structure 3 to cooperate with the elastic component 202 of the suspension system 200, and improves the assembly stability of the movable structure 3 and the elastic component 202, thereby improving the assembly stability and assembly efficiency of the suspension system 200.

[0070] For the suspension system 200 according to the second aspect embodiment of the present invention, referring to Figure 8 , the suspension system 200 includes the support assembly 100 according to the above first aspect embodiment of the present invention.

[0071] For the suspension system 200 according to the present invention, by adopting the above support assembly 100, double-stage decoupling is achieved, effectively reducing the yaw stiffness of the suspension system 200, while ensuring the stability and comfort of the suspension system 200.

[0072] According to some embodiments of the present invention, referring to Figure 8 and Figure 9 , the suspension system 200 further includes a shock absorber 201 and an elastic component 202.

[0073] Specifically, the shock absorber 201 includes a cylinder block 2011 and a piston rod 2012. One end of the piston rod 2012 is arranged inside the cylinder block 2011, the other end of the piston rod 2012 extends outside the cylinder block 2011, and the other end of the piston rod 2012 is connected to the movable structure 3 of the support assembly 100. The elastic component 202 includes an upper air chamber 2021. The upper air chamber 2021 is arranged on the outer peripheral side of the shock absorber 201. One end of the upper air chamber 2021 close to the support assembly 100 is connected to the piston rod 2012, and the end of the upper air chamber 2021 close to the support assembly 100 has a stepped portion 2021a, and the stepped portion 2021a is fitted on the stepped surface of the support assembly 100.

[0074] For example, in Figure 8and Figure 9 In the example of Figure 9 , the lower end of the piston rod 2012 is arranged inside the cylinder block 2011, the upper end of the piston rod 2012 extends out of the cylinder block 2011, and the upper end of the piston rod 2012 sequentially passes through the second through-hole section 131 and the mating hole 32 to be connected with the movable structure 3, so as to realize the assembly of the support combination assembly 100 and the shock absorber 201. The upper end of the upper air chamber 2021 is sleeved on the outer peripheral side of the upper end of the piston rod 2012, and the step portion 2021a is arranged at the upper end of the upper air chamber 2021. The shape of the upper side surface of the step portion 2021a is adapted to the shape of the step surface. With such an arrangement, the cooperation between the step portion 2021a and the step surface increases the contact area between the upper air chamber 2021 and the movable structure 3, thereby enhancing the assembly tightness between the upper air chamber 2021 and the movable structure 3. Through the movable structure 3, the rotation of the piston rod 2012 relative to the upper air chamber 2021 is also avoided, improving the use stability of the suspension system 200.

[0075] In addition, when the upper end of the upper air chamber 2021 cooperates with the movable structure 3, after the piston rod 2012 of the shock absorber 201 deflects, it drives the cylinder block 2011 to deflect synchronously. The upper end of the upper air chamber 2021 is fixedly connected to the upper end of the piston rod 2012, and the upper air chamber 2021 will also deflect synchronously. The air spring component 205 of the elastic component 202 connected to the lower end of the upper air chamber 2021 also deflects synchronously. The air spring component 205 is sleeved outside the cylinder block 2011. Since the volume inside the air spring components 205 on both the left and right sides of the shock absorber 201 does not change and is the same as the initial state, there is no relative movement between the air spring component 205 and the shock absorber 201, and no lateral force is generated. Thus, the adverse effects brought by the deflection are alleviated. Furthermore, the suspension system 200 can effectively reduce the lateral force received by the shock absorber 201, thereby enhancing the stability of the vehicle body 301 of the vehicle 300 and strengthening the buffering effect of the suspension system 200. Moreover, the sealing performance and buffering performance of the air spring component 205 can also be improved, enhancing the stability and reliability of the suspension system 200.

[0076] In addition, the support combination assembly 100, by working together with the air spring component 205 and the shock absorber 201, can significantly reduce the lateral force received by the shock absorber 201, effectively reduce the yaw stiffness, thereby extending the service lives of the shock absorber 201, the air spring component 205 and the support combination assembly 100, improving the comfort level, and providing a better driving and riding experience for the vehicle 300. However, it is not limited to this. The suspension system 200 can be a MacPherson structure or a multi-link structure. The shock absorber 201 can be a hydraulic shock absorber, an electromagnetic shock absorber, etc., and is used in cooperation with the support combination assembly 100. The size and assembly position of the support combination assembly 100 can be flexibly designed according to needs. When the elastic component 202 includes a coil spring (not shown in the figure), the upper mounting seat of the coil spring can be integrally provided with the second support seat 13.

[0077] According to some embodiments of the present invention, referring to Figure 8 and Figure 9 , there is a first gap 203 between the outer peripheral surface of one end of the elastic component 202 close to the support assembly 100 and the buffer 2 of the corresponding support assembly 100; and / or, there is a second gap 204 between the outer peripheral surface of one end of the elastic component 202 close to the support assembly 100 and the inner wall surface of the second through-hole section 131 of the support assembly 100.

[0078] According to some other embodiments of the present invention, referring to Figure 8 and Figure 9 , there is a first gap 203 between the outer peripheral surface of one end of the elastic component 202 close to the support assembly 100 and the buffer 2 of the corresponding support assembly 100.

[0079] For example, in the examples of Figure 8 and Figure 9 , the first gap 203 is formed between the outer peripheral side of the stepped portion 2021a of the upper air chamber 2021 and the inner peripheral side of the buffer 2. With such a setting, when the upper air chamber 2021 yaws along with the piston rod 2012, the stepped portion 2021a on the upper air chamber 2021 does not affect the deformation of the buffer 2, avoiding mutual interference between the buffer 2 and the upper air chamber 2021, so that the suspension system 200 can be used normally.

[0080] According to still some other embodiments of the present invention, referring to Figure 8 and Figure 9 , there is a second gap 204 between the outer peripheral surface of one end of the elastic component 202 close to the support assembly 100 and the inner wall surface of the second through-hole section 131 of the support assembly 100.

[0081] For example, in the examples of Figure 8 and Figure 9 , the second gap 204 is formed between the outer peripheral side of the upper air chamber 2021 and the side wall of the second through-hole section 131. With such a setting, when the upper air chamber 2021 yaws along with the piston rod 2012, the second gap 204 reserves a moving space for the upper air chamber 2021, effectively avoiding interference between the upper air chamber 2021 and the second support seat 13, so that the suspension system 200 can be used normally. Moreover, the synchronous yaw movement of the upper air chamber 2021 and the piston rod 2012 is realized, the air pressure inside the air spring component 205 is stabilized, and the additional lateral force between the air spring component 205 and the shock absorber 201 is eliminated. Among them, a buffer block 206 is provided on the inner side wall of the upper air chamber 2021, compared with the traditional technology provided on the upper support assembly, the lightweight design of the support assembly 100 is realized.

[0082] A sealing ring 207 is provided between the inner side surface of the stepped portion 2021a and the outer peripheral surface of the piston rod 2012 to seal the movable structure 3, the piston rod 2021, and the upper air chamber 2021 from each other, preventing dust, oil, water, gas, etc. from entering the inside of the air spring component 205, effectively avoiding affecting the service performance of the air spring component 205, and also enabling the movable structure 3, the piston rod 2021, and the upper air chamber 2021 to be fixed to each other to prevent relative rotation.

[0083] The piston rod 2012 passes through the support assembly 100, and the top of the piston rod 2012 is press-fitted to the support assembly 100 through a fastener 5 (such as a round nut). The air spring component 205 is of a single-chamber type. The air spring component 205 includes a first hoop 2051, a clamping ring 2052, a bladder 2053, a protective shell 2054, a second hoop 2055, and a dust cover 2056. The bladder 2053 is the core part of the air spring component 205, having good elasticity and sealing performance, and capable of adjusting the stiffness and suspension height of the air spring component 205 through its own expansion and contraction. The bladder 2053 is sleeved on the outer peripheral side of the cylinder block 2011 of the shock absorber 201. The first hoop 2051 seals and presses the upper end of the bladder 2053 to the upper air chamber 2021. The clamping ring 2052, as an important connecting component between the air spring component 205 and the shock absorber 201, connects the lower end of the bladder 2053 to the cylinder block 2011 and prevents external air pressure from entering the inside of the air spring component 205 during installation. The protective shell 2054 is sleeved on the outer peripheral side of the bladder 2053 to protect the bladder 2053. The protective shell 2054 can be made of aluminum alloy, and the bladder 2053 can be made of rubber. The dust cover 2056 prevents dust and other impurities below the shock absorber 201 from entering the air spring component 205. The second hoop 2055 connects the protective shell 2054 and the dust cover 2056, and the connection is achieved through interference fit. In the direction of the kinematic pair, the piston rod 2012 and the cylinder block 2011 form a sliding pair, and the bladder 2053 and the cylinder block 2011 also form a sliding pair.

[0084] According to a second aspect embodiment of the present invention, for the vehicle 300, referring to Figure 11 , the vehicle 300 includes the support assembly 100 according to the above first aspect embodiment of the present invention, or the suspension system 200 according to the above second aspect embodiment of the present invention.

[0085] For the vehicle 300 according to the present invention, by adopting the above support assembly 100 or suspension system 200, while maintaining the controllability of the vehicle 300, the riding comfort is also significantly improved.

[0086] The other configurations and operations of the suspension system 200 and the vehicle 300 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail here.
