Description

Technical Field

[0001] This utility model relates to the technical field of treadmill accessories, and in particular to a composite running board and a treadmill. Background Technology

[0002] With the improvement of people's living standards and the promotion of national fitness activities, the demand for treadmills is increasing. Treadmills are suitable for indoor use, occupy little space, and are loved by many users. Existing treadmills include a support frame, a running board body fixed to the bottom of the support frame, two axles respectively mounted on both sides of the running board body, and a running belt wound around the axles. The top side of the running belt is supported by the running board body, allowing the user to step on it to achieve the purpose of running and exercising. Existing running boards are generally made of high-density or medium-density fiberboard, which is relatively heavy and has poor cushioning. During exercise, the foot makes direct hard contact with the running board body through the running belt, resulting in a large impact on the knees. At the same time, the friction noise between the running belt and the running board body is also relatively high. Therefore, a composite running board and treadmill are provided to solve the above problems. Utility Model Content

[0028] Please see Figures 1-3As shown, the composite running board 10 of this utility model is mainly used in treadmills or walking machines. It includes a load-bearing base plate 11, a noise-reducing buffer layer 12, a PP honeycomb layer 13, and a supporting top plate 14. The load-bearing base plate 11 is the main load-bearing component, and the supporting top plate 14 is in contact with the running belt, with the supporting top plate 14 positioned opposite to the load-bearing base plate 11. The noise-reducing buffer layer 12 and the PP honeycomb layer 13 are disposed between the load-bearing base plate 11 and the supporting top plate 14, and the noise-reducing buffer layer 12 and the PP honeycomb layer 13 work together to perform buffering and noise reduction. In this embodiment, the load-bearing base plate 11, the noise-reducing buffer layer 12, the PP honeycomb layer 13, and the supporting top plate 14 are arranged sequentially from bottom to top; in other embodiments, the load-bearing base plate 11, the PP honeycomb layer 13, the noise-reducing buffer layer 12, and the supporting top plate 14 are arranged sequentially from bottom to top. Specifically, the load-bearing base plate 11 is made of carbon fiber, glass fiber, or glass fiber reinforced polypropylene, enabling it to withstand greater pressure.

[0029] Please see Figures 1-5 As shown, in this embodiment, the noise-reducing buffer layer 12 is made of space cotton. Space cotton has a special multi-layered microporous structure, which helps absorb sound and reduce standing waves in the speaker, thus achieving noise reduction. The noise-reducing buffer layer 12 includes a supporting base 121 and multiple noise-reducing mechanisms 122. The supporting base 121 is mounted on the load-bearing base plate 11, and the multiple noise-reducing mechanisms 122 are evenly distributed on the supporting base 121 and penetrate through the PP honeycomb layer 13. The multiple noise-reducing mechanisms 122 and the PP honeycomb layer 13 work together to achieve the buffering and noise-reducing function. Preferably, the supporting base 121 and the multiple noise-reducing mechanisms 122 are integrally formed. Specifically, the noise-reducing mechanism 122 includes at least one annular protruding inclined surface, which, in conjunction with the hollow cavity 131 on the PP honeycomb layer 13, quickly eliminates vibration sound waves. In this embodiment, the noise reduction mechanism 122 includes a first annular raised inclined surface 1221, a second annular raised inclined surface 1222, and a protrusion 1223. The first annular raised inclined surface 1221 and the second annular raised inclined surface 1222 are integrally formed and disposed on the supporting bottom layer 121. The second annular raised inclined surface 1222 is disposed in the inner ring of the first annular raised inclined surface 1221, and the protrusion 1223 is integrally formed and protrudes from the inner ring of the second annular raised inclined surface 1222. The protrusion 1223 further weakens the reflected sound waves, thereby further improving the noise reduction effect. In other embodiments, the number of annular raised inclined surfaces can be one, three, four, or other plurality of surfaces, and the number can be set according to actual needs.

[0030] Please see Figure 2 , Figure 3 and Figure 6As shown, in this embodiment, the PP honeycomb layer 13 has the characteristics of being lightweight, pressure-resistant, sound-absorbing, heat-insulating, corrosion-resistant, and bending-resistant. Multiple hollow cavities 131 are disposed through it, and multiple noise reduction mechanisms 122 are respectively disposed through the corresponding hollow cavities 131. Specifically, the outer contour shape of the hollow cavity 131 can be circular or polygonal; in this embodiment, the outer contour shape of the hollow cavity 131 is a regular hexagon.

[0031] Please see Figures 1-3 As shown, the material of the supporting top plate 14 can be high-density board or medium-density board. In this embodiment, the material of the supporting top plate 14 is rectangular medium-density board. A melamine resin coating is provided on the side of the supporting top plate 14 that contacts the running belt, thereby enhancing the wear resistance of the supporting top plate 14. A melamine coating is provided on the outer wall of the supporting top plate 14, thereby enhancing the heat insulation performance of the side wall of the supporting top plate 14.
