Treadmill Walking Board Assembly Having Functions of Flow Guidance, Air Exhaust and Heat Dissipation

Abstract

A treadmill walking board assembly includes a base board, a wear-resistant thin layer located above the base board, and a heatsink elastic layer arranged between the base board and the wear-resistant thin layer. The heatsink elastic layer is provided with a plurality of heat dissipation holes and a plurality of recessed flow channels. The flow channels define a plurality of circulation spaces between the heatsink elastic layer and the base board. The flow channels extend through a side edge of the heatsink elastic layer and are connected to each of the heat dissipation holes. Thus, when the user is stepping on the treadmill walking board assembly and presses the heatsink elastic layer, the hot air is delivered through the heat dissipation holes, the flow channels, and the side edge of the heatsink elastic layer.

1 . A treadmill walking board assembly comprising:
 a base board, a wear-resistant thin layer, and a heatsink elastic layer;   wherein:   the base board is made of wood material;   the wear-resistant thin layer is located above the base board;   the heatsink elastic layer is arranged between the base board and the wear-resistant thin layer;   the heatsink elastic layer has a top face abutting the wear-resistant thin layer and a bottom face abutting the base board;   the heatsink elastic layer is provided with a plurality of heat dissipation holes;   the heat dissipation holes perforate the top face and the bottom face of the heatsink elastic layer;   the heatsink elastic layer is provided with a plurality of recessed flow channels;   the flow channels are formed in the bottom face of the heatsink elastic layer and define a plurality of circulation spaces between the heatsink elastic layer and the base board;   the flow channels extend through a side edge of the heatsink elastic layer; and   the flow channels are connected to a lower end of each of the heat dissipation holes.   
     
     
         2 . The treadmill walking board assembly as claimed in  claim 1 , wherein the heatsink elastic layer is made of foam material. 
     
     
         3 . The treadmill walking board assembly as claimed in  claim 1 , wherein the heat dissipation holes are arranged in a vertical direction. 
     
     
         4 . The treadmill walking board assembly as claimed in  claim 1 , wherein:
 the flow channels extend through the heatsink elastic layer transversely;   the flow channels are arranged regularly; and   the flow channels are adjacent to each other.   
     
     
         5 . The treadmill walking board assembly as claimed in  claim 1 , wherein:
 the flow channels extend through the heatsink elastic layer longitudinally;   the flow channels are arranged regularly; and   the flow channels are adjacent to each other.   
     
     
         6 . The treadmill walking board assembly as claimed in  claim 1 , wherein the flow channels are arranged irregularly. 
     
     
         7 . The treadmill walking board assembly as claimed in  claim 1 , wherein each of the flow channels has a cross section defining an arcuate concave face. 
     
     
         8 . The treadmill walking board assembly as claimed in  claim 1 , wherein the flow channels are arranged linearly. 
     
     
         9 . The treadmill walking board assembly as claimed in  claim 1 , wherein:
 the flow channels are formed in the top face of the heatsink elastic layer and define a plurality of circulation spaces between the heatsink elastic layer and the wear-resistant thin layer; and   the flow channels are connected to an upper end of each of the heat dissipation holes.   
     
     
         10 . The treadmill walking board assembly as claimed in  claim 1 , wherein:
 the wear-resistant thin layer is provided with a plurality of heatsink holes; and   the heatsink holes perforate the wear-resistant thin layer.
