[0030] As Figures 1-9 shown, the embodiment of the application discloses a double-pulley running board motor mounting structure, which is installed on one side of a treadmill close to a front roller 200 and is used for providing driving force for the front roller 200. The treadmill comprises a support frame 100, the support frame 100 is a rectangular frame, comprising two support tubes 110 arranged in parallel, a plurality of support bars 120 are arranged along the length direction of the support tube 110, the two ends of the support bar 120 are fixedly connected with the corresponding side support tube 110, so that the support strength of the support frame is improved; the upper surface of the support tube 110 is provided with a connecting part 1200.

[0031] The front end of the support frame body 100 is provided with a front roller 200, and a motor 600 is arranged on one side of the front roller 200 and provides driving force; the rear end of the support frame body 100 is provided with a rear roller 300 parallel to the front roller 200, and a running belt 400 is connected to the front roller 200 and the rear roller 300, and under the rotation of the front roller 200 and the rear roller 300, the running belt 400 is driven to rotate in one direction; the running belt 400 is a long hollow ring, and a running plate 500 is arranged in the hollow ring. The running belt 400 wraps the support frame body 100, and a movement contact plane is formed on the upper side of the support frame body 100; the output shaft of the motor 600 is connected to the front roller 200, so as to drive the front roller 200 to rotate, and the front roller 200 drives the running belt 400 to move on the movement contact plane.

[0032] In the embodiment of the present application, the lengths of the support pipes 110 on the two sides are inconsistent, and the front end face of the support pipe 110 on one side is spaced apart from the front roller 200, so as to form a space for accommodating a motor mounting shell 700, and the motor mounting shell 700 is mounted in the space and is welded and fixed to the support pipe 110 on the side. Not only can the overall structure be more compact and the overall volume be reduced, but also the movement transmission distance can be shortened and the transmission efficiency can be improved.

[0033] Specifically, the motor mounting shell 700 has an elongated mounting cavity 710, the top of the elongated mounting cavity 710 is an open structure, and the motor 600 is arranged in the mounting cavity 710; the mounting cavity 710 extends away from the rear roller 300 to a position corresponding to the front roller 200; the side wall of the motor mounting shell 700 close to the running plate 500 is a first side wall 720, the top of the first side wall 720 is provided with a horizontal bend 721, the horizontal bend 721 is fixedly connected to the bottom of the running plate 500; a second side wall 730 of the motor mounting shell 700 is arranged opposite to the first side wall 720; the output shaft of the motor 600 penetrates through the second side wall 730; the motor 600 and a double-belt-pulley transmission structure connected to the motor 600 are arranged in the mounting cavity 710, the double-belt-pulley transmission structure is connected to the front roller 200, and movement transmission is realized; the double-belt-pulley transmission structure is arranged, so as to gradually transmit the power output by the motor 600 to the front roller 200, and the stability of transmission is improved. The horizontal bend 721 is attached to the bottom surface of the running plate 500 and is fixed to the running plate 500 by screws. Since the width of the motor mounting shell 700 is wide and only the end face of the shorter support pipe 110 is fixedly connected, the stability is affected, especially during the operation of the motor 600, vibration is easily caused, a connecting point is additionally arranged, and the mounting stability of the motor mounting shell 700 is improved.

[0034] The double-belt wheel transmission structure comprises a first belt wheel 800 connected with the motor 600 through a first belt 810 and a second belt wheel 900 coaxially connected with the front roller 200, and the second belt wheel 900 is connected with the first belt wheel 800 through a second belt 910. The rotating shaft of the first belt wheel 800 penetrates through the second side wall 730 of the motor mounting shell, and the first belt wheel 800 has a driving wheel A and a driven wheel B coaxially arranged. The diameter of the driving wheel A is larger than that of the driven wheel B, and the width of the wheel surface of the driving wheel A is larger than that of the second belt wheel 900, so as to reduce the occurrence of the belt displacement and the disengagement of the driving wheel A, and improve the operation stability. The output shaft of the motor 600 is connected with the driving wheel A through the first belt 810, and the driven wheel B is connected with the second belt wheel 900 through the second belt 910.

The opening 510 is a long strip shape, and the length thereof is matched with the motor mounting shell 700, so as to reserve the installation space of the motor mounting shell 700.

[0036] The motor 600 and the double-belt wheel transmission structure are all mounted in the motor mounting shell 700. Only one opening 510 for accommodating the motor mounting shell 700 needs to be formed in the running plate 500, thereby improving the machining efficiency and eliminating the need for forming multiple openings for accommodating various components.

[0037] In the embodiment of the present application, the support pipe 110 is a square hollow pipe, which ensures the strength while reducing the weight of the support pipe 110, thereby reducing the weight of the whole machine.

[0038] In the embodiment of the present application, the support pipe 110 is provided with a protective cover 1100 at the rear end thereof.

[0039] In the embodiment of the present application, at least one cushion block 1000 is arranged at the lower side of each support pipe 110, which is used for preventing slipping and sound insulation. Preferably, the cushion block 1000 is arranged at a position deviated to the rear of the support pipe 110. The cushion block 1000 has a slight elasticity, and can be made of rubber, silica gel or PVC material, so as to better provide damping and buffering performance. In order to further improve the friction resistance of the cushion block 1000, a plurality of micro convex particles are formed on the bottom of the cushion block 1000, so as to enhance the friction force when the cushion block 1000 contacts with the ground.
