[0029] Embodiment

[0030] As Figure 1 Indicated, the utility model proposes a kind of automobile shock absorber spring, including two groups of parallelly arranged mounting plate 1, the middle position of two groups of mounting plate 1 is respectively provided with through hole 11, it is convenient to pass through damping rod to form damper whole by the arrangement of through hole 11, to realize the assembly cooperation of spring and damping rod, two groups of mounting plate 1 are fixedly arranged after being installed to damper, prevent the abrasion caused by the deflection of mounting plate 1 when first spring 2 is deformed, guarantee the stability and structural integrity when spring works.

[0031] Further, the above-mentioned damper spring includes a first spring 2 connected between the two mounting plates 1, the first spring 2 is fixedly connected to the two mounting plates 1 at both ends, and bears the main shock absorption function in daily driving to provide basic elastic buffer.

[0032] Further, please refer to Figures 1 to 3The damper spring further comprises a load mechanism 3 arranged between the two groups of mounting plates 1, which is used to play a buffering role when the first spring 2 is subjected to high load, effectively sharing the overload pressure, and avoiding the first spring 2 from being broken due to excessive load. The load mechanism 3 comprises a first mounting ring 31 arranged between the two groups of mounting plates 1, one side of the first mounting ring 31 is provided with a first mounting cylinder 32, the outer side of the first mounting cylinder 32 is provided with a second spring 33, and the two ends of the second spring 33 are fixedly connected with the first mounting ring 31 and the mounting plate 1 respectively, preventing the second spring 33 from being deformed to rub against the mounting plate 1 and the first mounting ring 31 to cause wear, thereby prolonging the service life of the second spring 33. The load mechanism 3 further comprises a second mounting ring 34 arranged on the side of the first mounting ring 31 away from the first mounting cylinder 32, and the second mounting ring 34 is arranged in parallel with the first mounting ring 31. The second mounting ring 34 is provided with a second mounting cylinder 35 on the side away from the first mounting ring 31, and the outer side of the second mounting cylinder 35 is provided with a third spring 36. The two ends of the third spring 36 are fixedly connected with the second mounting ring 34 and the mounting plate 1 respectively, preventing the third spring 36 from being deformed to rub against the mounting plate 1 and the second mounting ring 34 to cause wear, thereby ensuring the long-term stable operation of the third spring 36. Four groups of limiting rods 37 are fixedly connected to the side of the first mounting ring 31 close to the second mounting ring 34, and the four groups of limiting rods 37 all penetrate through the second mounting ring 34 and the second mounting cylinder 35. The second mounting ring 34 and the second mounting cylinder 35 are in sliding connection with the limiting rods 37. Through the action of the limiting rods 37, the second mounting ring 34 and the first mounting ring 31 are stably close to each other and cannot rotate relative to each other, so that the buffering process of the load mechanism 3 is more orderly and reliable. The ends of the multiple groups of limiting rods 37 away from the first mounting ring 31 are fixedly connected with a limiting ring 38, which prevents the second mounting ring 34 and the second mounting cylinder 35 from being separated from the limiting rods 37 through the limiting action of the limiting ring 38, thereby ensuring the stability of the structure of the load mechanism 3. When the first spring 2 is subjected to a higher load, the distance between the two groups of mounting plates 1 is smaller, so that the first mounting ring 31 and the second mounting ring 34 are in close contact, and at the same time, the second spring 33 and the third spring 36 are compressed and deformed, thereby improving the load capacity and enhancing the buffering performance of the spring under overload conditions.

[0033] Finally, the damper spring described above comprises two groups of mounting plates 1, each of which is provided with a first positioning ring 12 on one side, and the first positioning ring 12 is located outside the first spring 2, and the first positioning ring 12 is used to limit the first spring 2, improve the accuracy of its position, and prevent the first spring 2 from deviating during work. Two groups of mounting plates 1 are respectively provided with a second positioning ring 13 and a third positioning ring 14 on one side, the second positioning ring 13 is located inside the second spring 33 or the third spring 36, and the third positioning ring 14 is located between the second spring 33 or the third spring 36 and the first spring 2, the second positioning ring 13 and the third positioning ring 14 are used to improve the accuracy of the position of the second spring 33 and the third spring 36, and ensure that each spring maintains the correct installation position and stress direction during work. The inner diameter of the second positioning ring 13 is equal to the diameter of the through hole 11, and the outer diameter of the limiting ring 38 is smaller than the diameter of the through hole 11. When the two groups of mounting plates 1 are very close, the limiting ring 38 can slide into the through hole 11, effectively improving the stroke, and further improving the buffering effect of the spring under extreme load.

[0034] In this embodiment, during normal driving of the automobile, the vibration and impact of the road are transmitted to the shock damper spring through the damping rod. At this time, the first spring 2 bears the main shock absorbing function by virtue of its elastic deformation, absorbs vibration energy through compression and expansion, provides basic elastic cushioning for the automobile, and maintains the stability of vehicle driving.

[0035] When the automobile drives on complex road conditions, the first spring 2 bears high load, and the two groups of mounting plates 1 are close to each other under the action of impact force. With the reduction of the distance between the mounting plates 1, the load mechanism 3 begins to play a role: the first mounting ring 31 and the second mounting ring 34 gradually fit, at the same time, the second spring 33 and the third spring 36 are compressed and elastically deformed. During the compression deformation of the second spring 33 and the third spring 36, part of the overload impact force is converted into the elastic potential energy of the spring, sharing the pressure borne by the first spring 2, avoiding the fracture of the first spring 2 due to excessive load.

[0036] In this process, the limiting rod 37 ensures that the second mounting ring 34 and the first mounting ring 31 are close to each other stably, prevents the two from rotating when stressed, so that the buffering process of the load mechanism 3 is more orderly and stable; the limiting ring 38 prevents the second mounting ring 34 and the second mounting cylinder 35 from separating from the limiting rod 37, and guarantees the structural integrity of the load mechanism 3.

[0037] In addition, the first positioning ring 12, the second positioning ring 13 and the third positioning ring 14 position the first spring 2, the second spring 33 and the third spring 36 respectively, ensure that the springs keep accurate installation positions and stable stress directions in the working process, and avoid affecting the damping effect due to spring deviation. When the two groups of mounting plates 1 are extremely close, the limiting ring 38 can slide into the through hole 11 by virtue of the design that the outer diameter of the limiting ring 38 is smaller than the diameter of the through hole 11, further increase the stroke of the spring, thereby improving the buffering capacity of the spring under extreme load, and maximizing the reliability and safety of the automobile damping system.

[0038] The above specific embodiments are only optional embodiments of the utility model, and based on the technical scheme of the utility model and the related inspiration of the above embodiments, the person skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
