Running belt 400 wraps support frame body 100, forms the movement contact plane on the upper side of support frame body 100, the output shaft of motor 600 is connected to front cylinder 200, drives front cylinder 200 to rotate, and front cylinder 200 drives 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 both sides are inconsistent, and the front end surface of the support pipe 110 on one side is spaced apart from the front roller 200, serving as a space for accommodating the motor mounting shell 700. The motor mounting shell 700 is mounted in the space and is welded and fixed with 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 motion 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 which is an open structure for placing the motor 600. The motor 600 is fixedly mounted in the mounting cavity 710. The mounting cavity 710 is elongated and 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 which is formed with a horizontal bend 721, which is fixedly connected with the bottom of the running plate 500. The motor 600 and a double pulley transmission structure connected therewith are mounted in the mounting cavity 710. The double pulley transmission structure is connected with the front roller 200 to realize motion transmission. The double pulley transmission structure is provided to gradually transmit the power output by the motor 600 to the front roller 200, thereby improving the stability of transmission.

[0036] In the embodiment of the application, the support pipe 110 is a square hollow pipe, which ensures the strength while reducing the weight of the support pipe 110, and further reduces the weight of the whole machine.

[0037] In the embodiment of the application, the support pipe 110 is connected with a protective cover 1100 at the rear end.

[0038] In the embodiment of the application, at least one pad 1000 is arranged on the lower side of each support pipe 110, which is used for preventing sliding and sound insulation. Preferably, the pad 1000 is arranged at a rear position of the support pipe 110. The pad 1000 has micro elasticity and can be made of rubber, silica gel or PVC material, which can better provide damping and buffering performance. In order to further improve the friction resistance of the pad 1000, micro convex particles are formed on the bottom of the pad 1000, which can enhance the friction force when the pad 1000 contacts with the ground.
