Description of the Invention: [Technical Field] The present invention relates to a treadmill, and more particularly to a running board for a treadmill. [Prior Art] A treadmill is a fairly common indoor sports equipment, and mainly uses one. The running belt allows the user to perform running training in situ, in order to allow the running belt to continue to run. The treadmill usually provides a running board as a running belt. The conventional running board mainly forms a groove on the top surface of a wooden substrate, and a shock absorbing layer is disposed in the groove to provide a buffering effect. However, when people run on the actual road, they often land on the heel. At this time, the body receives the greatest impact force, then gradually transfers the force to the whole foot, and finally uses the forefoot lamp to leave the ground to make the body's center of gravity. Go forward and step on the next step. However, the groove depth of the wooden substrate provided by the conventional running board is uniform, so that the cushioning effect provided by the shock absorbing layer at any position is also the same, so when people step on the conventional running board for running training. At the time, the conventional running board has no way to simulate the impact force that the user receives when running on the actual road surface to provide an appropriate cushioning effect. SUMMARY OF THE INVENTION The main object of the present invention is to provide a running board for a treadmill, which can effectively simulate a user's actual running time on the road surface to provide an appropriate 201138897 buffering effect to improve the user's training performance. In order to achieve the above object, the running board of the present invention is used for providing support to a running belt, and comprises a wooden substrate and a shock absorbing layer, wherein the wooden substrate has a top surface and a recess formed by the top surface recessed. The depth of the groove is gradually reduced from the front end of the wooden substrate to the rear end of the wooden substrate for the shock absorbing layer to be disposed. In the embodiment of the present invention, the top surface of the wooden substrate and the top surface of the shock absorbing layer may be coplanar, and a top layer of the wooden substrate and a top surface of the shock absorbing layer may be provided with a strengthening layer for adding The structural strength of the invention. By the above design, the running board of the present invention can effectively simulate the running condition of the user on the actual road surface by using the design of the groove and the shock absorbing layer to provide an appropriate cushioning effect to improve the training performance. . [Embodiment] In order to explain the structure, features and effects of the present invention in detail, a preferred embodiment will be described with reference to the following drawings. Referring to the first figure, a running board (20) according to a preferred embodiment of the present invention is mounted on a treadmill (ίο) for providing support to a running belt (12). Please refer to Figures 2 to 3, the running board (2〇) includes a wooden substrate (30), a shock absorbing layer (40), and a reinforcing layer (5 〇). The wooden substrate (30) has a top surface (32) and a recess (34) formed by a recess formed by the top surface (32). The depth of the recess (34) is from the front end of the wooden substrate (3〇) to the wooden substrate (30). ) The end is gradually reduced. 4 201138897 The shock absorbing layer (40) is placed in the groove (34) of the wooden substrate (3〇) to provide a buffering effect' and the top surface of the shock absorbing layer (4〇) and the top surface of the wooden substrate (30) are Coplanar. The reinforcing layer (50) is made of Meinuo, and is disposed on the top surface of the wooden substrate (3〇) and the top surface of the shock absorbing layer (40) to increase the overall structural strength. According to the above structure, since the depth of the groove (34) of the wooden substrate (34) is gradually decreased from the front to the rear, the thickness of the shock absorbing layer (4〇) provided in the groove (34) is also gradually reduced from the front to the rear. It is divided into a first segment (42), a second segment (44), and a third segment (46). When a person performs running training and then the heel is stepped on the running board (2〇) of the present invention, the first section (42) of the shock absorbing layer (4) (with the deepest thickness) will provide appropriate cushioning force to reduce The impact on the human body, then when the force is gradually transferred to the full foot, the second section (44) of the shock absorbing layer (40) provides a cushioning force, and finally uses the forefoot light to leave On the ground, a second section (46) of the shock absorbing layer (4 〇) (having the shallowest thickness) provides cushioning force. Therefore, the running board (20) of the present invention can effectively simulate the impact force that the user receives when running on the actual road surface to provide an appropriate cushioning effect ′ to achieve the purpose of improving the training performance. The constituent elements disclosed in the foregoing embodiments are merely illustrative and are intended to limit the scope of the present invention. The alternative or variations of other equivalent elements are also covered by the scope of the patent application. 201138897 [Simple Description of the Drawings] The first figure is a perspective view of a treadmill to which a preferred embodiment of the present invention is applied.
