  • Patent number: 10449412
    Abstract: The invention relates to the treadmill technology, and more particularly to the low noise type direct drive type treadmill. It has solved the technical problems such as large output power loss and large noise. The low noise type direct-drive type treadmill includes a running platform, an endless running belt arranged on the running platform, a rotating roller arranged at one end of the running platform and a tubular motor arranged at the other end. The rotary roller and tubular motor is arranged parallel to each other and provided with a running belt fixed to the running platform between the rotating roller and the tubular motor, the annular running belt is arranged between the rotating roller and the tubular motor and the annular running belt is located on the periphery of the running belt when the tubular motor is operable to drive the endless running belt.

  • Patent number: 9937375
    Abstract: The invention belongs to the technical field of fitness equipment, in particular to the independent suspension vibration damping mechanism of running platform of a treadmill. It solves the problem that the shock effect of the existing treadmill is poor and so on. It includes the chassis and the runway frame. The front end of mentioned runway frame is suspended on the chassis by means of a suspension structure and when the runway frame is subjected to a downward force and forcing the front end of the runway frame to descend, the suspension structure can assist the front end of the runway frame to rise and reset. The independent suspension vibration damping mechanism of running platform of the treadmill has the advantages: simple structure, good stability, good shock absorption effect, providing shock absorption buffer to multiple locations of the treadmill, long span life, and high mechanical strength.
