Abstract

Claims (27)

1. A walking/treadmill with an integrated base, comprising an integrated base, a running board, a running belt, a motor, an electric control, and a drum;

wherein the running board, the running belt, the motor, the electric control, and the drum are installed in the integrated base;

the base comprises a transverse beam, a longitudinal beam, and an installation cavity shell provided between the transverse beam and the longitudinal beam;

the longitudinal beam and the installation cavity shell are both made of reinforced plastic with a predetermined mixing ratio and are injection molded;

wherein the longitudinal beam is wrapped with a metal reinforcement member that is extended along a length direction of the longitudinal beam;

wherein the metal reinforcement member is provided with a plurality of through holes that are spaced along a length direction of the metal reinforcement member and penetrate a wall of the metal reinforcement member;

the metal reinforcement member is provided with a plurality of convex strips or protrusions that are concave inward from one side of the wall of the metal reinforcement member and convex outward from the other side thereof.

2. The walking/treadmill with an integrated base according to claim 1 , wherein the reinforced plastic comprises polypropylene and glass fiber, or polyamide-6 and glass fiber, or polyamide-66 and glass fiber;

the glass fiber comprises continuous glass fiber and staple glass fiber.

3. The walking/treadmill with an integrated base according to claim 2 , wherein the reinforced plastic with a predetermined mixing ratio refers to a weight percentage of the glass fiber is more than or equal to 15%, and

wherein the reinforced plastic with a predetermined mixing ratio using a mixture of the acrylonitrile-butadiene-styrene copolymer and the polycarbonate refers to a weight proportion of the polycarbonate is more than or equal to 30%, and

the reinforced plastic has at least one of the following characteristics: a tensile strength of the reinforced plastic measured according to a tensile performance testing method for plastics is greater than or equal to 50 Mpa, a bending strength of the reinforced plastic measured according to a bending performance testing method for plastics is greater than or equal to 70 Mpa; a charpy notch impact strength of the reinforced plastic measured according to an impact resistance testing method for plastics is greater than or equal to 30 KJ/m 2 .

7. The walking/treadmill with an integrated base according to claim 1 , wherein the longitudinal beam and the transverse beam are both provided with reinforcing ribs that are formed with the transverse beam and the longitudinal beam,

wherein the longitudinal beam and the transverse beam are injection molded with the same reinforcing plastic.

8. A manufacturing method for the integrated base according to claim 1 , comprising the following steps:

S1: mixing and heating the reinforced plastic according to proportions and performing a granulation treatment with a granulator;

S2: heating and melting plastic particles and injecting them into a locked injection die by an injection molding machine;

S3: after completing the injecting of the plastic particles, maintaining a pressure;

S4: cooling the injection die to solidify a melt within a mould cavity of the injection die into the base;

S5: after cooling to room temperature, opening the injection die and demolding the base.

9. The manufacturing method for the integrated base according to claim 8 , wherein in step S2, before injecting plastic particles into an injection die by an injection molding machine, the metal reinforcement member is placed in the mould cavity of the injection die corresponding to the transverse beam.
