[0026] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0027] In the related art, a buffer pad is arranged on a suspension swing arm, and a spring is arranged inside the buffer pad. There is a gap in the connection between the buffer pad and the suspension swing arm. When the vehicle is driving, the suspension swing arm moves up and down, and the suspension swing arm cannot transmit force evenly to the buffer pad. The uneven force on the buffer pad causes the buffer pad to be unable to transmit force evenly to the spring, resulting in relative movement between the spring and the buffer pad. This relative movement causes the buffer pad to deform, which aggravates the wear of the buffer pad. At the same time, there is a risk that the spring will fall out of the buffer pad.

[0028] Reference below Figure 1-Figure 3 A suspension assembly according to the present embodiment is described.

[0029] According to the utility model, the suspension assembly 100 includes: a suspension swing arm 111, a spring 21 and a buffer pad 11, a mounting seat is formed on the suspension swing arm 111; at least one end of the spring 21 forms a connecting end; the buffer pad 11 is fixed to the connecting end of the spring 21, and a mounting plane suitable for abutting against the mounting seat is formed on the side of the buffer pad 11 away from the spring 21.

[0030] In some specific embodiments, the suspension assembly 100 is composed of a suspension swing arm 111, a spring 21 and a buffer pad 11. A mounting seat is formed on the suspension swing arm 111, and connecting ends are respectively formed at both ends of the spring 21. The buffer pad 11 is constructed in two, one of which is arranged on the mounting seat and is connected and fixed to one of the springs 21, and the other buffer pad 11 is fixed to the other connecting end of the spring 21. A mounting plane is formed on the side of the buffer pad 11 away from the spring 21, and the mounting plane can be stopped against at least part of the wall surface of the mounting seat. During the movement of the suspension swing arm 111, the mounting seat can transfer force to the buffer pad 11 more evenly, and each position on the mounting plane of the buffer pad 11 is subjected to uniform force. When the buffer pad 11 then transfers the force evenly to the spring 21, the force applied to each position of the connecting end of the spring 21 is relatively balanced, thereby effectively preventing the spring 21 from being unevenly subjected to force and escaping from the buffer pad 11 during the process of force being transmitted from the buffer pad 11 to the spring 21, thereby improving the stability and reliability of the connection between the spring 21 and the buffer pad 11.

[0031] According to the utility model, a mounting seat is formed on the cantilever assembly through the suspension swing arm 111, and the buffer pad 11 is arranged in the mounting seat and fixed to the connecting end of the spring 21. A suitable mounting plane is formed on the side of the buffer pad 11 away from the spring 21, and the mounting plane can stop at least part of the wall surface of the mounting seat. During the movement of the suspension swing arm 111, the mounting seat can transfer force to the buffer pad 11 more evenly, and each position on the mounting plane is subjected to uniform force. When the buffer pad 11 then transfers the force evenly to the spring 21, the force applied to each position of the connecting end of the spring 21 is relatively balanced, thereby effectively preventing the spring 21 from being unevenly subjected to force and escaping from the buffer pad 11 during the process of force being transferred from the buffer pad 11 to the spring 21, thereby improving the stability and reliability of the connection between the spring 21 and the buffer pad 11.

[0032] According to an embodiment of the present invention, a positioning protrusion 12 is formed at the end of the buffer pad 11 facing the spring 21 , the spring 21 is arranged around the outer periphery of the positioning protrusion 12 , and a limiting portion 13 is formed on the buffer pad 11 to limit the movement of the spring 21 in the axial direction.

[0033] In some specific embodiments, a positioning protrusion 12 is formed on one side of the buffer pad 11 toward the end of the spring 21, and the positioning protrusion 12 extends toward the end of the spring 21. The spring 21 is sleeved on the outer periphery of the positioning protrusion 12. On the one hand, the positioning protrusion 12 can increase the contact area between the spring 21 and the buffer pad 11, thereby improving the stability and reliability of the spring 21 on the buffer pad 11. On the other hand, the positioning protrusion 12 has a certain positioning and guiding function, thereby making the assembly between the spring 21 and the buffer pad 11 simple and quick, thereby improving the assembly efficiency of the cantilever assembly.

[0034] In addition, a limiting portion 13 is provided on the buffer pad 11, and the limiting portion 13 can be axially abutted against the spring 21 to limit the axial movement of the spring 21 relative to the buffer pad 11, further improving the stability and reliability of the connection between the buffer pad 11 and the spring 21.

[0035] According to an embodiment of the present invention, the limiting portion 13 is disposed on the outer periphery of the positioning protrusion 12 and is spaced apart from the buffer pad 11 to form a limiting groove 103 for accommodating the spiral section of the spring 21 .

[0036] In some specific embodiments, a limiting portion 13 extending radially is formed on the outer peripheral wall of the positioning protrusion 12, the limiting portion 13 is spaced apart from the buffer pad 11, and a limiting groove 103 recessed in a direction away from the buffer pad 11 is formed on the side of the limiting portion 13 facing the buffer pad 11, the spiral section of the spring 21 is accommodated in the limiting groove 103, and when the spring 21 and the limiting groove 103 are assembled, when the spring 21 shows an axial movement tendency relative to the buffer pad 11, at least part of the wall surface of the rotating section of the spiral spring 21 abuts against the limiting groove 103 in the axial direction, thereby limiting the axial movement of the spring 21 relative to the buffer pad 11, improving the stability and reliability of the connection between the buffer pad 11 and the spring 21, and at the same time, the design of the limiting groove 103 can make the installation and disassembly of the spring 21 simpler and more convenient, thereby improving the matching efficiency of the spring 21 and the buffer pad 11.

[0037] According to an embodiment of the present invention, the limiting portions 13 are configured to be a plurality of the limiting portions 13 that are spaced apart in the circumferential direction of the positioning protrusion 12 .

[0038] In some specific embodiments, the limiting portions 13 are constructed to be multiple and are arranged at intervals along the circumference of the positioning protrusion 12. The multiple limiting portions 13 can provide more support points, increase the contact area between the buffer pad 11 and the spring 21, thereby improving the stability and reliability of the connection between the buffer pad 11 and the spring 21. The multiple limiting portions 13 can fix the spring 21 from multiple different directions in the circumferential direction. At the same time, when the spring 21 is subjected to external force, the multiple limiting portions 13 can share the load together, reduce the pressure borne by a single limiting portion 13, and effectively prevent the spring 21 from radially escaping from a certain limiting portion 13, thereby further improving the stability and reliability of the connection between the spring 21 and the buffer pad 11.

[0039] According to one embodiment of the utility model, the groove 101 formed on the limiting portion 13 is constructed to be the same as the cross-section of the spiral section of the spring 21. Since the structure of the limiting groove 103 matches the cross-sectional shape of the spiral section of the spring 21, the spring 21 can be more stably installed in the limiting groove 103, reducing the instability factors caused by the loosening or falling off of the spring 21. This design can ensure that the spring 21 can be accurately aligned and positioned with the limiting groove 103 during installation, thereby improving the installation accuracy and working performance of the equipment. The close combination of the spiral section of the spring 21 and the limiting limit can provide a better buffering effect when the spring 21 is impacted or vibrated, thereby reducing the risk of damage to the equipment.

[0040] According to an embodiment of the present invention, the buffer pad 11 is configured as a rubber piece and is fixed to the end of the spring 21 by vulcanization.

[0041] In some specific embodiments, the ends of the buffer pad 11 and the spring 21 are vulcanized into an integrated structure through a vulcanization process. The vulcanization integration of the spring 21 and the buffer pad 11 avoids the possibility of abnormal noise caused by compression and deformation of the spring 21 and friction between the buffer pad 11 during suspension movement, and can also reduce the possibility of other foreign objects entering the connection between the spring 21 and the buffer pad 11. At the same time, the risk of wear and tear of the spring 21 caused by friction between the coating of the spring 21 and foreign objects during long-term use, resulting in the risk of rusting of the spring 21, and the phenomenon of stretching and de-coating of the spring 21, which reduces the quality problems caused by the improper assembly of the spring 21 and the buffer pad 11, thereby improving the integration of the suspension assembly 100.

[0042] The buffer pad 11 is made of rubber material and has excellent elasticity and deformation ability, which enables it to effectively alleviate vibration and impact. The rubber material itself has vibration absorption performance, and the special design structure of the rubber buffer pad 11 further enhances its shock absorption effect and helps to absorb noise and vibration. The rubber buffer pad 11 can maintain its basic performance over a wide temperature range and can maintain its excellent buffering effect regardless of high or low temperature environment. In addition, the rubber buffer pad 11 has a small mass, making its installation and removal simple and quick.

[0043] The specific assembly process of the spring 21 and the buffer pad 11: the spring 21 is ready for use after the plastic spraying is completed. The buffer pad 11 is constructed into an upper buffer pad 11 and a lower buffer pad 11. The upper buffer pad 11 and the lower buffer pad 11 are vulcanized by a mold to obtain a vulcanized part with a stable structure. The vulcanized adhesive is coated on both ends of the spring. The adhesive coating area is larger than the pre-pressed contact area. At the same time, the upper buffer pad 11 and the lower buffer pad 11 are respectively assembled with the two ends of the spring 21. After the assembly is completed, they are placed in the secondary vulcanization assembly for heating and vulcanization. After the vulcanization of the buffer pad 11 and the spring 21 is completed, they are removed and placed in the storage rack. Finally, the buffer pad 11 and the spring 21 are directly assembled on the suspension swing arm 111 as a whole.

[0044] According to an embodiment of the present invention, the buffer pad 11 is formed with a protruding or recessed friction portion 14 on the installation plane.

[0045] In some specific embodiments, the buffer pad 11 is formed with a mounting plane on the side facing the mounting seat, and a friction portion 14 is formed on the mounting plane, which is recessed toward the direction close to the spring 21 or protrudes toward the direction away from the spring 21. The design of the friction portion 14 can form a certain space on the surface of the buffer pad 11, which is conducive to air circulation and prevents the buffer pad 11 from being deformed or aged due to long-term pressure. The friction portion 14 can increase the friction between the buffer pad 11 and the mounting seat to prevent the buffer pad 11 from sliding or shifting when it is impacted, thereby ensuring that the buffer pad 11 can function stably. The design of the friction portion 14 can visually increase the aesthetics of the buffer pad 11, so that it not only has practical functions, but also gives people a comfortable feeling visually.

[0046] According to one embodiment of the utility model, the friction portion 14 is constructed to extend radially on the mounting plane and be arranged at intervals in the circumferential direction. The multiple friction portions 14 are arranged at intervals in the circumferential direction to increase the contact area with the mounting seat, thereby increasing the friction force, helping to prevent the buffer pad 11 from sliding or shifting on the mounting seat, and improving the stability and reliability of the integrated structure of the buffer pad 11 and the spring 21 on the mounting seat. At the same time, when the integrated structure of the buffer pad 11 and the spring 21 is subjected to external force, the multiple friction portions 14 can share the stress together, reduce the pressure borne by a single friction portion 14, reduce the wear and damage of the friction portion 14, and extend the service life of the integrated structure of the buffer pad 11 and the spring 21.

[0047] According to an embodiment of the present invention, the mounting seat is configured as a recessed groove 101 on the suspension swing arm 111 , the recess 101 is suitable for accommodating the buffer pad 11 and the bottom wall of the recess 101 abuts against the mounting plane.

[0048] In some specific embodiments, the suspension swing arm 111 is constructed as an H-shaped swing arm, and the mounting seat can be constructed as a groove 101 recessed on the suspension swing arm 111. The buffer pad 11 is accommodated in the groove 101 and the bottom wall of the groove 101 abuts against the mounting plane, so that the force applied to the buffer pad 11 during the swinging of the suspension swing arm 111 can be more uniform, effectively preventing a part of the buffer pad 11 from being separated from the mounting seat due to excessive force, thereby improving the stability and reliability of the buffer pad 11 in the mounting seat; since the bottom wall of the groove 101 can be in close contact with the mounting plane, the buffer pad 11 can more effectively transmit and disperse the force to the mounting seat when subjected to impact or vibration, thereby reducing damage to the integrated structure of the buffer pad 11 and the spring 21 and extending its service life.

[0049] In addition, the stop design between the bottom wall of the groove 101 and the mounting plane makes the installation process of the buffer pad 11 easier. The user only needs to place the buffer pad 11 at the appropriate position in the groove 101 and ensure that the bottom wall of the groove 101 is in close contact with the mounting plane to complete the installation. This design reduces the complexity of the installation process and improves the assembly efficiency of the buffer pad 11 and the mounting seat.
