[0035] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0036] In some embodiments, reference is made to Figure 1 , Figure 2The suspension system provided by the embodiments of the present application comprises a buffer structure 10, a damping device 20 and an air spring 30. Exemplarily, the buffer structure 10 comprises a buffer block 11 and a mounting hole 101, and the buffer block 11 comprises a mounting groove 111 and an external support ring 112, wherein the mounting groove 111 is arranged on the outer side of the buffer block 11 and used for mounting the external support ring 112.
[0037] Exemplarily, the damping device 20 comprises a cylinder, a piston and a piston rod (not shown in the figure), one end of the piston rod is connected with the air spring 30 through the mounting hole 101, the air spring 30 is connected to the vehicle body 40 (or a vehicle frame) through a connecting member (for example, a bolt or the like), and the other end is connected to the vehicle axle 50 (for example, a wheel hub or a drive shaft). When the vehicle body 40 and the vehicle axle 50 move relatively due to vibration, the piston in the shock absorber moves up and down, which can play a role of buffering and damping, and improve the comfort of the whole vehicle.
[0038] In some embodiments, along the second direction Z, the air spring 30 comprises a top end 301 and a bottom end 302, the top end 301 is used for being connected with the vehicle body 40, the buffer structure 10 is arranged at the top end 301, and the damping device 20 is arranged at the bottom end 302 of the air spring 30. Exemplarily, in the air spring 30, the piston rod is arranged in the mounting hole 101 along the second direction Z. It can be understood that the buffer structure 10 provided by the embodiments of the present application is not limited to being arranged in the air spring 30, for example, it can also be arranged in a common spring, which is not limited by the present application.
[0039] The external support ring 112 arranged on the outer side of the buffer block 11 can improve the buffering performance of the buffer block 11 to a certain extent, but when the piston of the shock absorber frequently moves up and down and hits the buffer block 11 during the driving of the vehicle, the support ring is easy to fall off from the buffer block 11, which shortens the service life of the buffer block 11, reduces the buffering and damping performance of the buffer block 11, and affects the normal use of the suspension system. In addition, in the suspension system using the air spring 30, the buffer block 11 without the support ring or with the external support ring 112 is easy to cause damage to the air spring 30, and the air spring 30 emits a larger noise.
[0040] Based on this, in order to solve the problem that the external support ring 112 of the buffer block 11 is easy to fall off in the foregoing embodiments, the buffer structure 10 is improved and designed according to the embodiments of the present application. Figures 3 to 7

Meanwhile, the main body 12 is not provided with the external support ring 112, so that the risk of falling off of the external support ring 112 is avoided, and the safety performance of the buffer structure 10 is ensured. For example, the air spring 30 does not have the risk of damage or noise caused by falling off of the external support ring 112. Therefore, the buffer structure 10 provided by the application can be used in combination with the air spring 30 to improve the buffering and damping performance of the air spring 30.
[0043] In some embodiments, referring to Figure 3 , Figure 4 , Figure 5 and combining with Figure 1 , the support part 13 comprises an inner wall 131 and an outer wall 132. The inner wall 131 and the outer wall 132 are arranged at intervals along the first direction Y. The outer wall 132 is embedded in the main body 12, and the first inner diameter d1 of the inner wall 131 along the first direction Y is equal to the second inner diameter d2 of the mounting hole 101. Exemplarily, the first inner diameter d1 is greater than the second inner diameter d2. The embodiments of the application do not limit the size of the first inner diameter d1 and the second inner diameter d2. It is only required that the first inner diameter d1 of the inner wall 131 along the first direction Y is not less than the second inner diameter d2 of the mounting hole 101.

The three support parts 13 are arranged at intervals along the second direction Z in the main body 12, and each support part 13 is arranged around the mounting hole 101. It can be understood that the number of the support parts 13 can be two, four, five, six, seven or the like. That is, the number of the support parts 13 is at least one, and the embodiments of the application do not limit this.
[0045] In some embodiments, referring to Figure 5 , Figure 6 , Figure 7The buffer structure 10 is in a cylindrical shape as a whole, the support part 13 is in a ring shape, and the support part 13 is made of metal or hard plastic. In some embodiments, the buffer structure 10 comprises a convex part 14 arranged on the outer side of the main body 12, and the outer side of the main body 12 does not comprise a groove for mounting the external support ring 112. Exemplarily, the convex part 14 and the main body 12 are arranged integrally, the outer side of the main body 12 does not comprise a groove for mounting the external support ring 112, the material waste of the buffer structure 10 can be avoided, the production cost of the buffer structure 10 is reduced, and the convex part 14 arranged on the outer side of the main body 12 can further improve the buffering and shock absorption performance of the buffer structure 10 as a whole.
