[0033] Example 1: See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A crawler treadmill includes a frame 1 and a front roller 2 and a rear roller 3 arranged at the front and rear ends of the frame 1 respectively. A crawler running belt 4 is arranged on the frame 1. A motor device 5 is arranged on the frame 1 between the front roller 2 and the frame 1. The motor device 5 is connected to the front roller 2 through a transmission belt 6. The motor device 5 is located on the frame 1 inside the crawler running belt 4. This arrangement does not affect the normal operation of the crawler running belt 4, and also maximizes the running area. Since the motor device 5 is present on the frame 1 between the front roller 2 and the frame 1, it is beneficial to avoid adding an additional transmission wheel design, greatly reducing the difficulty and cost investment of production and manufacturing, and also helping to reduce the overall volume, thereby reducing the space occupied by later placement. Other treadmill designs on the frame 1 are well known to those skilled in the art and will not be repeated here. For example, a support frame (not shown in the figure) for supporting is provided on the frame 1 to facilitate supporting the frame 1.
[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the motor device 5 includes a fixing frame 51 disposed on the frame 1, and a motor 52 is disposed on the fixing frame 51. The motor 52 and the fixing frame 51 are fixedly connected via a fixing assembly 53. The fixing frame 51 is U-shaped, and the motor 52 moves back and forth on the U-shaped fixing frame 51, which is conducive to adjusting the position of the motor 52 on the fixing frame 51. An output wheel is disposed on the output shaft of the motor 52, and the output wheel is connected to the front roller 2 via a transmission belt 6, which is conducive to driving the front roller 2 to rotate through the motor 52. Since the front roller 2 and the rear roller 3 are connected via the crawler running belt 4, the crawler running belt 4 is rotated, which is conducive to the user running on it. Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the fixing assembly 53 is inserted from the lower surface of the fixing frame 51 to fix the motor 52, which is conducive to reducing the occupied space.
