Detailed Description

Fig. 1 to 6 show specific structures of embodiments of the present invention.

A shock-absorbing wear-resistant foot pad comprises an elastic rubber shell 10 and EVA foaming fillers 20; the elastic rubber shell 10 is provided with a bottom wall 11 and a side wall 12 which are connected, and an accommodating cavity with an opening at the upper end is formed by enclosing the bottom wall 11 and the side wall 12; the EVA foaming filler 20 is positioned in the accommodating cavity; the tops of the EVA foam filler 20 and the side wall 12 serve as supporting sides, and the bottom of the bottom wall 11 serves as a placing side. Thus, the foot pad of the utility model has good buffering and damping effects, good wear resistance and high practicability by arranging the containing cavity in the elastic rubber shell 10 and arranging the EVA foaming filler 20 in the containing cavity; meanwhile, in the aspect of manufacturing and production, the foot pad also has the advantages of simple manufacturing process, low manufacturing cost and the like.

Further, the method comprises the following steps: the EVA foaming filler 20 is formed by foaming EVA materials after being placed in the accommodating cavity. Therefore, the filling and bonding are easy to manufacture and stable in filling and bonding.

Typically, the tops of both the EVA foam filler 20, the sidewall 12, remain flush; alternatively, the top of the EVA foam filler 20 is lower than the top of the side wall 12. Therefore, the glue is convenient to be adhered to the bottom of the product, and the influence on the appearance caused by the overflow of the glue is avoided.

Preferably, the bottom wall 11 of the elastic rubber shell 10 is downward convex, and the inner bottom surface of the accommodating cavity and the bottom of the EVA foaming filler 20 are correspondingly downward convex. Thus, the method has the advantages of easy manufacture and filling in manufacture.

Preferably, the bottom of the bottom wall 11 is provided with anti-skid protrusions 13 at intervals to improve the anti-skid performance of the foot pad. Specifically, the stud 13 is a strip-shaped stud; meanwhile, the strip-shaped antiskid projections also play a role of reinforcing ribs. Preferably, as shown in the drawings, the extending direction of the base wall is offset from the extending direction of the bottom wall 11; and a plurality of foot pads are arranged at intervals on the placing side of the foot pad.

Preferably, the elastic rubber shell 10 is made of PU or TPU. Thus, during production, the material is easy to obtain, and the rubber has the advantages of wear resistance, oil resistance, transparency, good elasticity, easy molding and manufacturing and the like.

Preferably, the wall thickness of the side wall 12 is gradually increased downwards, and the thickness of the bottom wall 11 is greater than that of the lower section of the side wall 12. Therefore, the structural strength is good, a reliable support frame is provided, and meanwhile, the upper wall is thin, so that trace deformation matching can be realized during EVA foaming filling, and the manufacturing yield is improved; meanwhile, the bottom of the bottom wall 11 of the foot pad is usually a part which is worn more as a placing side, and the wear resistance is effectively improved and the service life is prolonged by increasing the thickness of the part; and, through increase thickness, the effectual elasticity that improves the callus on the sole, the shock-absorbing capacity is also better.

Further, in a top view, the elastic rubber case 10 is integrally of an arc-shaped structure, and the accommodating cavity and the EVA foam filler 20 are correspondingly of an arc-shaped structure. Therefore, the arc-shaped structure has the advantages of wide application range and strong universality, can be matched with the shapes of the bottoms of different products, and can provide a larger supporting surface compared with the conventional existing straight strip-shaped or L-shaped structure.

Meanwhile, the utility model also discloses an electronic product, which is applied with the damping wear-resistant foot pad; the supporting side of the shock-absorbing wear-resistant foot pad is fixedly bonded to the bottom of the electronic product.
