[0025] Combine the following Figures 1 to 3 The tension structure of the present invention is described.

[0026] like Figures 1 to 3 As shown, the present invention provides a tension structure, including an elastic covering member 1, a spring 2, a first connecting member 3 and a second connecting member 4, the spring 2 is arranged inside the elastic covering member 1, one end of the spring 2 is connected to the first connecting member 3, and the other end of the spring 2 is connected to the second connecting member 4.

[0027] In the tension structure provided in this embodiment, the first connecting member 3 and the second connecting member 4 are respectively connected to the parts that need to be fixed. For example, when applied to a vehicle, the first connecting member 3 and the second connecting member 4 are respectively connected to the frame and the wheel. The elastic covering member 1 and the spring 2 jointly achieve the effects of shock absorption and convergent vibration. The elastic covering member 1 is coated on the outside of the spring 2, and the elastic covering member 1 has a accommodating cavity for accommodating the spring 2 inside. The elastic covering member 1 is affected by temperature and time during deformation and deformation recovery, and can show obvious stress relaxation and creep phenomena, which is particularly obvious under vibration or alternating stress. Therefore, the characteristics of rubber can be used to reduce the convergence time of the natural vibration of the spring 2, reduce the amplitude of the spring 2, and achieve better convergence effect, better shock absorption effect, better anti-collision effect, better fixing effect, and lower cost.

[0028] In some embodiments, the shape of the spring 2 is S-shaped, which has better shock absorption and buffering effects.

[0029] In some embodiments, the elastic covering member 1 covers the spring 2 and fits tightly with the spring 2. The characteristics of rubber can reduce the convergence time of the natural vibration of the spring 2 and reduce the amplitude of the spring, resulting in better convergence effect and better shock absorption effect.

[0030] In some embodiments, both ends of the spring 2 are provided with limit rings 5 ​​, which are arranged inside the elastic covering member 1 to prevent the spring 2 from loosening.

[0031] In some embodiments, the first connecting member 3 and the second connecting member 4 are both ring-shaped, which makes installation more convenient.

[0032] In some embodiments, the elastic covering member 1 is made of rubber. The characteristics of rubber can be used to reduce the convergence time of the natural vibration of the spring 2 and reduce the amplitude of the spring 2, resulting in a better convergence effect.

[0033] In some embodiments, the elastic covering member 1 is made of elastic plastic, which can reduce the convergence time of the natural vibration of the spring 2 and reduce the amplitude of the spring 2, thereby achieving a better convergence effect.

[0034] In some embodiments, the resonant frequency of the elastic covering member 1 is different from the resonant frequency of the spring 2 to avoid resonance phenomenon that may damage parts.

[0035] In some embodiments, the tension structure further includes a connecting component 6, and the spring 2 is connected to the second connecting member 4 via the connecting component 6. By providing the connecting component 6, it can adapt to more installation environments and has better adaptability.

[0036] In some embodiments, the connecting assembly 6 includes a first stud 61, a second stud 62, a first nut 63, a second nut 64 and a connecting tube 65. The first nut 63 and the second nut 64 are respectively fixedly connected to the two ends of the connecting tube 65. One end of the first stud 61 is connected to the spring 2, the other end of the first stud 61 is connected to the first nut 63, one end of the second stud 62 is connected to the second connecting member 4, and the other end of the second stud 62 is connected to the second nut 64. The length of the entire shock-absorbing structure can be extended to adapt to different installation environments and have better adaptability.

[0037] In some embodiments, the connecting tube 65 is in the shape of a hexagonal prism for easy twisting.
