[0002] With the continuous development of the economy, people's living standards are constantly improving, and their demands for quality of life are also increasing. As an indispensable means of transportation, automobiles are also subject to increasingly higher requirements for comfort. The suspension system, as the main component supporting the powertrain, connects the powertrain and the body. Its main function is to support the powertrain, reduce the impact of powertrain vibration on the entire vehicle, and limit the amount of powertrain vibration. It plays a significant role in the vehicle's NVH (Noise, Vibration, Harshness) performance.

[0003] At present, the suspension system of most models on the market is a bushing-type suspension structure, that is, the bushing is pressed into the suspension bracket, and then the bracket is connected to the engine or transmission. At the same time, in order to protect the suspension bracket and limit it in the axial direction, two anti-collision pads are usually installed on both sides of the suspension.

[0004] In the prior art, crash pads are generally connected to the inner tube of the suspension by bonding. This method has a complex processing technology, low production efficiency, and is likely to increase product production costs. When the crash pads are not firmly bonded, there is a risk of protection failure, which is not conducive to improving the durability and reliability of the suspension. Utility Model Content

[0005] In view of this, the present invention aims to provide a suspension assembly to increase the durability and reliability of the suspension assembly.

[0010] Furthermore, the bracket protection portion is integrally formed with the main spring body, and the bracket protection portion includes an annular flange formed on the outer periphery of the main spring body, and the end of the annular flange away from the main spring body is wavy.

[0011] Furthermore, the suspension bracket is made of plastic.

[0012] Furthermore, a limiting protrusion protruding into the bushing mounting hole is provided on the hole wall, and the limiting protrusion is embedded in the rubber main spring.

[0013] Furthermore, the suspension bracket is provided with a plurality of insert mounting holes, and an insert is installed in each of the insert mounting holes, and each of the inserts is provided with a connection hole for connecting to the powertrain.

[0014] Furthermore, the plurality of insert mounting holes are located on one side of the suspension bracket relative to the bushing mounting hole, and a first annular reinforcing rib and a first strip reinforcing rib are provided on the other side of the suspension bracket; the first annular reinforcing rib is in an elongated strip shape and extends circumferentially around the bushing mounting hole;

[0015] A plurality of first strip-shaped reinforcement ribs are provided on both sides of the first annular reinforcement rib, and the plurality of first strip-shaped reinforcement ribs on each side extend from the first annular reinforcement rib in a direction away from the first annular reinforcement rib, and the extension direction is consistent with the axial direction of the bushing mounting hole, and the plurality of first strip-shaped reinforcement ribs on each side are arranged along the circumferential spacing of the bushing mounting hole.

[0016] Furthermore, a second strip reinforcement rib, a third strip reinforcement rib and a second annular reinforcement rib are provided on both sides of the suspension bracket; the second strip reinforcement rib and the third strip reinforcement rib are arranged crosswise, and the second annular reinforcement rib is provided at the intersection of the second strip reinforcement rib and the third strip reinforcement rib; the second strip reinforcement rib is connected between adjacent insert mounting holes, or the second strip reinforcement rib is connected between the bushing mounting hole and the insert mounting hole.

[0017] Furthermore, an anti-slip structure is provided between the insert and the suspension bracket, and the anti-slip structure is used to prevent the insert from detaching from the suspension bracket along the axial direction of the connecting hole; and / or, a rotation-stopping structure is provided between the insert and the suspension bracket, and the rotation-stopping structure is used to prevent the insert from rotating relative to the suspension bracket around the axial direction of the connecting hole.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The suspension assembly described in the present invention, the suspension bracket is the basic part of the suspension assembly, it has a bushing mounting hole, which can facilitate the installation of the bushing component, the rubber main spring is connected between the inner tube and the hole wall of the bushing mounting hole, and can play a key buffering and shock-absorbing role, so that the rubber main spring includes two parts: the main spring body and the bracket protection part. Among them, the main spring body is the main part of the rubber main spring, which is responsible for providing the main elasticity and shock-absorbing functions, and the bracket protection part is arranged at both ends of the main spring body, which protrudes along the axial direction of the bushing mounting hole toward the direction away from the main spring body. This structure can effectively protect the suspension bracket from direct impact and wear along the axial direction of the bushing mounting hole, can better protect the suspension bracket, and is conducive to increasing the durability and reliability of the suspension assembly.

[0020] Compared to existing crash pads bonded to the inner tube, the bracket guard in this suspension assembly performs the same function as existing crash pads. It can be integrally molded with the main spring body, reducing the number and type of suspension assembly components and the investment required to manufacture separate crash pad molds, thereby increasing the integration level of the suspension assembly. Because the bracket guard is integrated into the main spring body, it eliminates the problem of the crash pad falling off during transportation, resulting in higher safety and reliability.

[0021] Secondly, the inner ring connection part is the innermost part of the rubber main spring. It is covered on the outer surface of the inner tube, which can ensure a firm connection between the rubber main spring and the inner tube, thereby ensuring the structural stability of the entire bushing assembly. The outer ring connection part is located at the outermost layer of the rubber main spring. It is sleeved on the outside of the inner ring connection part and connected to the hole wall of the bushing mounting hole, which can facilitate the connection between the rubber main spring and the suspension bracket, ensuring that the bushing assembly can be firmly installed on the suspension bracket. The inner and outer ring connection parts can not only enhance the overall strength of the rubber main spring, but also ensure the coordinated deformation between the inner ring connection part and the outer ring connection part, thereby improving the shock absorption performance of the bushing assembly. The bracket protection part is located on the outer ring connection part or the inner and outer ring connection parts, which can better protect the suspension bracket from direct impact and wear.

[0022] Furthermore, the bracket guard and the main spring body are manufactured through an integrated molding process, which ensures a secure connection between the bracket guard and the main spring body, preventing failure of the bracket's protective performance due to a loose connection. This processing technology is simple and has high production efficiency. It does not require the subsequent bonding of the anti-collision pad, which helps reduce the production cost of the suspension assembly. The suspension bracket is made of plastic material, which can make the suspension assembly lighter, reducing the weight by approximately 35% compared to aluminum alloy. It has good corrosion resistance and low processing cost, and can save machining, pretreatment, assembly, pressing equipment, weight calibration and other steps. It has the advantages of simple production process, high efficiency and convenient manufacturing.

[0023] This also makes the suspension assembly more flexible in structural design, improves the material's environmental friendliness and ease of recycling. It can be injection molded with the rubber main spring, eliminating the need for separate outer tube preparation, processing, and assembly.

[0024] Furthermore, the provision of a limiting protrusion restricts the movement of the rubber main spring within the bushing mounting hole, ensuring its stable retention within the hole. This embedded structural design not only strengthens the connection between the rubber main spring and the suspension bracket, but also prevents displacement or dislodging of the rubber main spring when subjected to external forces, allowing the rubber main spring to better withstand vibration and impact, thereby extending the service life of the suspension assembly. Providing an insert mounting hole and installing an insert on the suspension bracket improves the reliability of the connection between the suspension bracket and the powertrain. The insert can be made of metal or other high-strength materials, for example, enabling the suspension bracket to withstand various loads and stresses from the powertrain.

[0025] The multiple insert mounting holes are located on one side of the suspension bracket relative to the bushing mounting holes. This layout allows the inserts to be concentrated on one side of the suspension bracket, facilitating connection to the powertrain. The first annular reinforcement rib and the first strip reinforcement rib work together to enhance the structural strength and rigidity of the suspension bracket, providing reliable protection for the normal operation of the suspension assembly. The second strip reinforcement rib, the third strip reinforcement rib, and the second annular reinforcement rib together form a complete and stable structural reinforcement system, which helps to effectively improve the structural strength and rigidity of the suspension bracket, and also enhance its anti-vibration performance, thereby extending the service life of the suspension assembly.

[0026] The anti-slip structure is mainly used to prevent the insert from detaching from the suspension bracket along the axial direction of the connecting hole. The main function of the anti-rotation structure is to prevent the insert from rotating relative to the suspension bracket around the axial direction of the connecting hole. The combination of the anti-slip structure and the anti-rotation structure can further improve the connection stability and reliability between the insert and the suspension bracket, extend the service life of the suspension assembly, and thus ensure stable and reliable use of the suspension assembly.

[0027] In addition, another object of the present invention is to provide a vehicle provided with the suspension assembly as described above.

[0028] The vehicle described in the present invention has the same beneficial effects as the above-mentioned suspension assembly, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Taking the vehicle in which the suspension assembly described in the present invention is located as an example, the directional words used in the embodiments, such as "up, down, left, right, front, and back", are based on the vehicle's position. Figure 4 The vehicle is defined based on the up-down direction (also known as the height direction, or the Z direction of the vehicle), the left-right direction (also known as the width direction, or the Y direction of the vehicle), and the front-back direction (also known as the length direction, or the X direction of the vehicle) in the shown state.

[0045] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0046] Example 1

[0047] This embodiment relates to a suspension assembly, which can solve the problem of anti-collision pads falling off due to collision during transportation and is conducive to improving the durability and reliability of the suspension assembly.

[0048] In terms of overall structure, combined Figures 1 to 6 As shown in FIG, the suspension assembly of this embodiment includes a suspension bracket 1 having a bushing mounting hole 11, and a bushing assembly 2 mounted in the bushing mounting hole 11. The bushing assembly 2 includes an inner tube 21 and a rubber main spring 22, and the rubber main spring 22 is connected between the inner tube 21 and the hole wall of the bushing mounting hole 11.

[0049] At this point, it can be understood that the suspension bracket 1 is the basic part of the suspension assembly. It has a bushing mounting hole 11, which can facilitate the installation of the bushing assembly 2. The rubber main spring 22 is connected between the inner tube 21 and the hole wall of the bushing mounting hole 11, which can play a key buffering and shock absorption role.

[0050] In addition, the rubber main spring 22 includes a main spring body 221 and bracket guards 222 provided at both ends of the main spring body 221. The bracket guards 222 at each end protrude in the axial direction away from the main spring body 221 along the bushing mounting hole 11, and the bracket guards 222 at each end protrude beyond the corresponding end of the suspension bracket 1.

[0051] It should be noted that, referring to Figure 3 and Figure 4 As shown in the figure, the corresponding end in this embodiment is the left end or right end of the suspension bracket 1 along the axial direction of the bushing assembly 2. The left end of the suspension bracket 1 is the corresponding end corresponding to the left end of the rubber main spring 22, and the right end of the suspension bracket 1 is the corresponding end corresponding to the right end of the rubber main spring 22.

[0052] Specifically, the bracket guard portion 222 at the left end protrudes beyond the left end of the suspension bracket 1, and the bracket guard portion 222 at the right end protrudes beyond the right end of the suspension bracket 1. It should be understood that the "beyond the corresponding ends" refers to the portion extending beyond both ends of the bushing mounting hole 11 of the suspension bracket 1 in the axial direction of the bushing mounting hole 11. In other words, the bracket guard portion 222 at the left end protrudes to the left of the leftmost end of the suspension bracket 1, and the bracket guard portion 222 at the right end protrudes to the right of the rightmost end of the suspension bracket 1.

[0053] As configured above, the rubber main spring 22 comprises a main spring body 221 and a bracket guard 222. The main spring body 221, as the primary component of the rubber main spring 22, provides primary elasticity and shock absorption. The bracket guards 222 are located at either end of the main spring body 221, projecting away from the main spring body 221 along the axis of the bushing mounting hole 11. This structure effectively protects the suspension bracket 1 from direct impact and wear along the axis of the bushing mounting hole 11, effectively protecting the suspension bracket 1 and increasing the durability and reliability of the suspension assembly.

[0054] Compared to existing crash pads bonded to the inner tube 21, the bracket guard 222 in this suspension assembly performs the same function as existing crash pads. It can be integrally formed with the main spring body 221, reducing the number and variety of suspension assembly components and the investment required to prepare separate crash pad molds, thereby increasing the integration level of the suspension assembly. Because the bracket guard 222 is integrated with the main spring body 221, it prevents the crash pad from falling off during transportation due to collisions, thereby enhancing safety and reliability.

[0055] It is worth mentioning that, in addition to being configured in a diamond-like shape, the inner tube 21 in this embodiment can also be designed and adjusted accordingly according to actual needs, such as being configured in a square shape. Furthermore, in other embodiments, the bushing assembly 2 may further include an outer tube sleeved over the inner tube 21, and an inner-outer tube connecting portion disposed between the outer tube and the inner tube 21. The rubber main spring 22 is connected between the outer tube and the inner tube 21. The specific structures of the outer tube and the inner-outer tube connecting portion can be referenced to the prior art and will not be further described here.

[0056] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 2 As shown in the figure, the rubber main spring 22 includes an inner ring connecting part 221A covered on the outside of the inner tube 21, an outer ring connecting part 221B sleeved on the outside of the inner ring connecting part 221A and connected to the hole wall, and an inner and outer ring connecting part 221C connected between the inner ring connecting part 221A and the outer ring connecting part 221B.

[0057] Here, the inner ring connection part 221A is the innermost part of the rubber main spring 22. It is covered on the outer surface of the inner tube 21, which can ensure the firm connection between the rubber main spring 22 and the inner tube 21, thereby ensuring the structural stability of the entire bushing assembly 2, and the outer ring connection part 221B is located at the outermost layer of the rubber main spring 22. It is sleeved on the outside of the inner ring connection part 221A and connected to the hole wall of the bushing mounting hole 11, which can facilitate the connection between the rubber main spring 22 and the suspension bracket 1, ensuring that the bushing assembly 2 can be firmly installed on the suspension bracket 1, and the inner and outer ring connection parts 221C provided can not only enhance the overall strength of the rubber main spring 22, but also ensure the coordinated deformation between the inner ring connection part 221A and the outer ring connection part 221B, thereby improving the shock absorption performance of the bushing assembly 2.

[0058] At the same time, the bracket protection portion 222 is provided on the outer ring connecting portion 221B or the inner and outer ring connecting portion 221C, thereby better protecting the suspension bracket 1 from direct impact and wear.

[0059] It is worth noting that in this embodiment of the suspension assembly, the inner tube 21 is used to cooperate with the supporting arm, and the specific structure of the supporting arm and the connection method between the supporting arm and the inner tube 21 can refer to the existing technology. In addition, in the vertical direction of the vehicle, the upper and lower ends of the inner and outer ring connecting portion 221C in this embodiment are respectively provided with stoppers 221D protruding toward the inner tube 21. Each stopper 221D can limit the supporting arm connected to the inner tube 21 in the vertical direction of the entire vehicle, thereby further improving the vibration reduction performance of the suspension assembly.

[0060] Furthermore, in this embodiment, as a preferred implementation form, Figure 3As shown in , the bracket protection portion 222 is integrally formed with the main spring body 221 , and the bracket protection portion 222 includes an annular flange 2221 formed on the outer periphery of the main spring body 221 .

[0061] Thus, the bracket guard portion 222 and the main spring body 221 are manufactured through an integrated molding process, ensuring a secure connection between the bracket guard portion 222 and the main spring body 221, thereby preventing failure of the bracket's protective performance due to a loose connection. This simple manufacturing process is highly efficient and eliminates the need for subsequent bonding of the crash pad, thus reducing the production cost of the suspension assembly.

[0062] It should be noted that the bracket guard portion 222 in this embodiment, in addition to being configured as an annular flange 2221, can also be configured as multiple flanges 2221 spaced apart along the circumference of the main spring body 221. In this case, the flanges 2221 can be circular, square, or other shapes. Furthermore, in addition to being provided on the outer circumference of the main spring body 221, the bracket guard portion 222 can also be provided at any location between the outer circumference of the inner tube 21 and the outer circumference of the main spring body 221, depending on actual needs. In this case, the bracket guard portion 222 can specifically be a protrusion or other structure.

[0063] It should also be noted that if Figure 3 As shown in FIG, both ends of the main spring body 221 are provided with an annular flange 2221, and the annular flanges on both sides are about the main spring body 221. Figure 3 In the state shown, the center lines in the left and right directions are arranged symmetrically.

[0064] In a preferred embodiment, the end of each annular flange 2221 away from the main spring body 221 is wavy. Specifically, taking the annular flange 2221 on the left as an example, the size of the annular flange 2221 protruding leftward from the main spring body 221 is gradually set along the circumferential direction of the main spring body 221. Figure 3 In the state shown in , the upper and lower parts of the annular flange 2221 protrude to the left to a larger extent, while the middle part of the annular flange 2221 protrudes to the left to a smaller extent, and the size changes gradually, so that the end of the annular flange 2221 away from the main spring body 221 is wavy.

[0065] The annular flange 2221 of such a structure can effectively reduce the external force step by step when the suspension assembly is subjected to an external force along its own axis, thereby better protecting the suspension bracket.

[0066] Furthermore, considering the lightweight requirements of the suspension assembly, in this embodiment, as a preferred embodiment, the suspension bracket 1 is made of plastic. Specifically, the suspension bracket 1 can be made of nylon, such as PA66-GF50, or other plastic materials.

[0067] The advantage of this arrangement is that it makes the suspension assembly lighter, which can reduce weight by about 35% compared to aluminum alloy materials. It has good corrosion resistance and low processing costs. It can save machining, pretreatment, assembly, pressing equipment, weight calibration and other steps. It has the advantages of simple and efficient production process and easy manufacturing. At the same time, it makes the suspension assembly more flexible in structural design, and can also improve the environmental friendliness of the material and the convenience of recycling.

[0068] In addition, the suspension bracket 1 can also be injection molded with the rubber main spring 22, which can save the need for separately preparing an outer tube, as well as the need for processing and assembling the outer tube.

[0069] Specifically, in this embodiment, as a preferred implementation form, Figure 4 As shown, the hole wall is provided with a limiting protrusion 111 protruding into the bushing mounting hole 11, and the limiting protrusion 111 is embedded in the rubber main spring 22. In the specific structure, the rubber main spring 22 is provided with an embedding groove 223 corresponding to each limiting protrusion 111. The limiting protrusion 111 is embedded in the embedding groove 223 to achieve the limiting of the rubber main spring 22.

[0070] Therefore, a limiting protrusion 111 is provided on the hole wall, and the limiting protrusion 111 is embedded in the rubber main spring 22, which can limit the movement of the rubber main spring 22 in the bushing mounting hole 11, ensuring that the rubber main spring 22 can be stably fixed in the hole. This embedded structure design can not only enhance the connection strength between the rubber main spring 22 and the suspension bracket 1, but also prevent the rubber main spring 22 from being displaced or falling off when subjected to external force, so that the rubber main spring 22 can better withstand vibration and impact force, thereby extending the service life of the suspension assembly.

[0071] For example Figure 4 As shown in FIG, limiting protrusions 111 are provided at both the upper and lower portions of the inner wall of the bushing mounting hole 11. It should be understood that the limiting protrusions 111 are provided to embed within the rubber main spring 22 and to effectively prevent the bushing assembly 2 from detaching from the suspension bracket 1 along the axial direction of the bushing mounting hole 11. Therefore, the number of limiting protrusions 111 may be two or other numbers, such as one, three, or four. The limiting protrusions 111 may be provided at other locations on the inner wall of the bushing mounting hole 11, in addition to being provided at the upper and lower portions of the inner wall of the bushing mounting hole 11.

[0072] In addition, in this embodiment, as a preferred embodiment, still refer to Figure 4 As shown in , a plurality of insert mounting holes 12 are provided on the suspension bracket 1, and an insert 3 is installed in each insert mounting hole 12, and each insert 3 is provided with a connection hole 31 for connecting to the powertrain.

[0073] Here, insert mounting holes 12 are provided on the suspension bracket 1, and inserts 3 are installed therein to improve the reliability of the connection between the suspension bracket 1 and the powertrain. Inserts 3 can be made of metal or other high-strength materials, for example, to enable the suspension bracket 1 to withstand various loads and stresses from the powertrain. Specifically, in this embodiment, three insert mounting holes 12 can be provided, arranged in a triangular pattern.

[0074] However, as a preferred embodiment, Figure 4 As shown in , in this embodiment, multiple insert mounting holes 12 are located on one side of the suspension bracket 1 relative to the bushing mounting holes 11. A first annular reinforcing rib 13 and a first strip reinforcing rib 14 are provided on the other side of the suspension bracket 1. Here, the multiple insert mounting holes 12 are located on one side of the suspension bracket 1 relative to the bushing mounting holes 11. This layout allows the inserts 3 to be concentrated on one side of the suspension bracket 1, facilitating connection to the powertrain.

[0075] The first annular reinforcing rib 13 is elongated and extends circumferentially around the bushing mounting hole 11. Multiple first strip-shaped reinforcing ribs 14 are provided on both sides of the first annular reinforcing rib 13. The multiple first strip-shaped reinforcing ribs 14 on each side extend from the first annular reinforcing rib 13 away from the first annular reinforcing rib 13, and the extension direction is consistent with the axial direction of the bushing mounting hole 11. The multiple first strip-shaped reinforcing ribs 14 on each side are arranged along the circumferential spacing of the bushing mounting hole 11. Therefore, the cooperation between the first annular reinforcing rib 13 and the first strip-shaped reinforcing rib 14 helps enhance the structural strength and rigidity of the suspension bracket 1, providing reliable protection for the normal use of the suspension assembly.

[0076] In the specific structure, in this embodiment, four first strip-shaped reinforcing ribs 14 can be provided, that is, two are provided on each side of the first annular reinforcing rib 13. Of course, in addition to providing four first strip-shaped reinforcing ribs 14, the design and adjustment can also be made accordingly according to actual needs, such as six or eight. At the same time, in addition to being provided as a long strip, the first annular reinforcing rib 13 can also be provided in other common shapes.

[0077] At the same time, in this embodiment, as a preferred implementation form, Figure 4 As shown, the suspension bracket 1 is provided with a second strip reinforcement rib 15, a third strip reinforcement rib 16 and a second annular reinforcement rib 17 on both sides. In addition, the second strip reinforcement rib 15 and the third strip reinforcement rib 16 are arranged crosswise, and a second annular reinforcement rib 17 is provided at the intersection of the second strip reinforcement rib 15 and the third strip reinforcement rib 16.

[0078] Here, the second strip reinforcement rib 15, the third strip reinforcement rib 16 and the second annular reinforcement rib 17 can together constitute a complete and stable structural reinforcement system, which is conducive to better improving the structural strength and rigidity of the suspension bracket 1, and can also improve its vibration resistance and extend the service life of the suspension assembly.

[0079] Moreover, the second strip-shaped reinforcement rib 15 is connected between adjacent insert mounting holes 12 , or the second strip-shaped reinforcement rib 15 is connected between the bushing mounting hole 11 and the insert mounting hole 12 .

[0080] In the specific structure, the second strip reinforcement ribs 15 in this embodiment can be set to four, that is, second strip reinforcement ribs 15 are provided between two adjacent insert mounting holes 12, between the insert mounting hole 12 located at the upper part of the suspension bracket 1 and the bushing mounting hole 11, and between the insert mounting hole 12 located at the upper part of the suspension bracket 1 and the connecting part between the insert mounting hole 12 and the bushing mounting hole 11 located in the middle part of the suspension bracket 1.

[0081] Furthermore, each second strip-shaped reinforcing rib 15 is provided with a third strip-shaped reinforcing rib 16 arranged crosswise therewith. In this case, each second strip-shaped reinforcing rib 15 is provided with one or two third strip-shaped reinforcing ribs 16. Specifically, the second strip-shaped reinforcing rib 15 located between the insert mounting hole 12 in the middle portion of the suspension bracket 1 and the insert mounting hole 12 in the lower portion of the suspension bracket 1 is provided with two third strip-shaped reinforcing ribs 16. Furthermore, each of the other second strip-shaped reinforcing ribs 15 is provided with one third strip-shaped reinforcing rib 16.

[0082] That is, two second annular reinforcing ribs 17 are provided between the insert mounting hole 12 located in the middle portion of the suspension bracket 1 and the insert mounting hole 12 located in the lower portion of the suspension bracket 1. Each of the other second strip-shaped reinforcing ribs 15 is provided with a second annular reinforcing rib 17, and each second strip-shaped reinforcing rib 15 and the corresponding third strip-shaped reinforcing rib 16 are connected to the outer edge of the corresponding second annular reinforcing rib 17. It should be understood that in other embodiments, each second strip-shaped reinforcing rib 15 and the corresponding third strip-shaped reinforcing rib 16 may also pass through the outer edge of the corresponding second annular reinforcing rib 17.

[0083] It is worth mentioning that the second annular reinforcement rib 17 in this embodiment can be set to be circular. Of course, in addition to being set to be circular, it can also be set to other shapes.

[0084] In addition, in this embodiment, as a preferred implementation form, Figure 6 As shown, an anti-slip structure 41 is provided between the insert 3 and the suspension bracket 1. The anti-slip structure 41 is used to prevent the insert 3 from detaching from the suspension bracket 1 along the axial direction of the connecting hole 31. Here, the anti-slip structure 41 is mainly used to prevent the insert 3 from detaching from the suspension bracket 1 along the axial direction of the connecting hole 31.

[0085] In the specific structure, the insert 3 includes a sleeve body 32, and a convex ring 411 is provided at both ends of the sleeve body 32. The convex ring 411 protrudes outward along the radial direction of the sleeve body 32. The reason for this arrangement is that: when the suspension bracket 1 is injection-molded, the insert 3 is first prepared in advance, and then the insert 3 is placed in the injection mold of the suspension bracket 1. During the injection molding process, the material will flow between the convex rings 411 at both ends. After the suspension bracket 1 is cooled and formed, the suspension bracket 1 has an embedded portion embedded between the two convex rings 411, and along the axial direction of the connecting hole 31, the end faces of the insert 3 at both ends are respectively coplanar with the end faces of the suspension bracket 1 at both ends, thereby forming an anti-slip structure 41, which can effectively prevent the insert 3 from detaching from the suspension bracket 1.

[0086] And, as another preferred embodiment, Figure 5 As shown, in this embodiment, a rotation-stopping structure 42 is provided between the insert 3 and the suspension bracket 1. The rotation-stopping structure 42 is used to prevent the insert 3 from rotating relative to the suspension bracket 1 about the axial direction of the connecting hole 31. In this case, the main function of the rotation-stopping structure 42 is to prevent the insert 3 from rotating relative to the suspension bracket 1 about the axial direction of the connecting hole 31.

[0087] In this embodiment, the anti-rotation structure 42 includes a rack 421 formed in the middle of the sleeve body 32 along its own axial direction. When the suspension bracket 1 is injection molded, the material will flow into the tooth groove of the rack 421, thereby better preventing the insert 3 from rotating relative to the suspension bracket 1 around the axial direction of the connecting hole 31.

[0088] In specific implementation, preferably, the anti-slip structure 41 and the anti-rotation structure 42 in this embodiment can be used in combination, that is, the insert 3 located at the upper and middle parts of the suspension bracket 1 of this embodiment is provided with a convex ring 411 and a rack 421, and the insert 3 located at the lower part of the suspension bracket 1 is only provided with a convex ring 411.

[0089] This further improves the stability and reliability of the connection between the insert 3 and the suspension bracket 1, extending the service life of the suspension assembly and ensuring stable and reliable use of the suspension assembly. It should be noted that the number of inserts 3 provided with both the protruding ring 411 and the rack 421 and the number of inserts 3 provided with only the protruding ring 411 is not limited herein; it is sufficient that both types of inserts 3 are provided simultaneously.

[0090] It should be understood that in other implementations, the three inserts 3 in this embodiment may all be provided with the convex ring 411 and the rack 421 , or the three inserts 3 may all be provided with only the convex ring 411 .

[0091] When using the suspension assembly of this embodiment, the bushing assembly 2 and insert 3 are preferentially prepared, and the flange 2221 and main spring body 221 are formed integrally through a molding process. The prepared bushing assembly 2 and insert 3 are then placed into an injection mold, and the suspension bracket 1 is then injection molded. This solves the problem of protection failure caused by loose adhesion of the crash pad, effectively protecting the suspension bracket 1 from direct impact and wear along the axial direction of the bushing mounting hole 11, effectively protecting the suspension bracket 1 and increasing the durability and reliability of the suspension assembly.

[0092] Example 2

[0093] This embodiment relates to a vehicle, on which the suspension assembly of the first embodiment is provided.

[0094] The vehicle of this embodiment utilizes the suspension assembly of Example 1. By integrating the bracket guard portion 222 with the main spring body 221 through an integrated process, the suspension bracket 1 is effectively protected from direct impact and wear along the axial direction of the bushing mounting hole 11. This effectively protects the suspension bracket 1 and enhances the durability and reliability of the suspension assembly. Furthermore, the integration of the bracket guard portion 222 with the main spring body 221 reduces the number and variety of suspension assembly components, reduces the investment in crash pad molds, and improves the integration of the suspension assembly product, thereby resolving the issue of crash pads falling off during transportation.

[0095] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
