Detailed Description

In order to better understand the purpose, function and specific design scheme of the present invention, the damping running board and the running machine of the present invention will be described in further detail with reference to the attached drawings.

As shown in figure 1, the shock-absorbing running board of the utility model comprises a shock-absorbing layer 1, a first base plate 2 is arranged on the first side surface of the shock-absorbing layer 1, and the first base plate 2 is arranged below the running belt and corresponds to the inner side surface of the running belt; a second base plate 3 is arranged on the second side surface of the shock absorption layer 1, and the second base plate 3 is connected with a frame body of the treadmill; the first side surface and the second side surface of the shock absorption layer 1 are arranged oppositely.

Specifically, the damping layer 1 is made of elastic materials, and the thickness of the damping layer 1 is 1mm-10 mm. The material of the damping layer 1 can be selected from one of slow-rebound high-density polyvinyl chloride foam board, polyvinyl chloride formate, PU, PVC, EVA high-elasticity sponge, PET foam and rubber. The high density polyvinyl chloride cystosepiment of kick-backing slowly that shock attenuation layer 1 of this embodiment chooseing for use makes, and the high density polyvinyl chloride cystosepiment of kick-backing slowly's coefficient of elasticity is high, the shock attenuation is effectual, simultaneously, because the porosity stable in structure of the high density polyvinyl chloride cystosepiment of kick-backing slowly self is the obturator structure basically, and the sound absorption performance is good, can also reduce the sound when running when having shock-absorbing function, further promotes user's the experience of running.

A first bonding layer 4 is arranged on the first side surface of the shock absorption layer 1, and the first substrate 2 is connected with the first bonding layer 4; the second side is provided with a second adhesive layer 5, and the second substrate 3 is connected to the second adhesive layer 5. The first bonding layer 4 and the second bonding layer 5 of this embodiment are all made of structural adhesive, and structural adhesive has high strength, can bear a large load, and is aging-resistant, fatigue-resistant, corrosion-resistant, and stable in performance in the expected life.

Preferably, as shown in fig. 2, the first adhesive layers 4 are provided at intervals on the first side surface of the shock-absorbing layer 1, and the first adhesive layers 4 are provided at intervals, so that a gap 6 is formed between two adjacent first adhesive layers 4. When the first substrate 2 is bonded with the damping layer 1, the first bonding layers 4 are deformed due to the extrusion of the first substrate 2 to the first bonding layers 4, and at the moment, a gap 6 between every two adjacent first bonding layers 4 provides a space for deformation; meanwhile, the gap between two adjacent first bonding layers 4 can also dredge air, and air bubbles generated when the first substrate 2 is bonded with the damping layer are reduced.
