SPECIFIC EMBODIMENT

[0043] The following specific embodiment of the invention including the technical solution of the present invention described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example 1

[0044] As it showed in picture 1-7, this kind of treadmill is consisted of rack 1, there is a round running band 2 in the rack 1, and there is a turning roller 3 in the rack 1, in another side of the rack, there is a electrical machine in the shape of tube 4, the turning roller 3 sets parallelly with the electrical machine in the shape of tube 4, and between the turning roller 3 and the electrical machine in the shape of tube 4, there is a stable running band 5 in rack 1, the round running band 2 stalls between the turning roller 3 and the electrical machine in the shape of tube 4, in addition, when the electrical machine in the shape of tube 4 is working, it can activate the round running band 2, and the round running band 2 stalls in the periphery of running band 5. After the activation of electrical machine in the shape of tube 4, it can activate the round running band 2 directly.

[0045] Optimum proposal, the electrical machine in the shape of tube 4 in this example is outer rotor tubular motor which includes outer rotor 41 and inner stator 42, and then the inner stator 42 fixes in the rack 1, and the round running band 2 is around the periphery of the outer rotor 41. In the next place, the length of outer rotor 41 is more than the width of the round running band 2.

[0046] In addition, the front of the rack 1 stalls on the bottle of the undercarriage 7 through the structure of suspension shock absorber, and when the rack 1 has the acting force from downward, it will force the rack 1 go down, the suspension shock absorber 6 can assist the rack 1 go back to the front. Specifically, the suspension shock absorber 6 in this example has two sets, and they stall in the two sides of the rack 1, each suspension shock absorber 6 has at least one cantilevel 61, and one side of it stalls jointly on the rack 1, the other side links with the undercarriage 7 through the elastic expansion assembly 62, the middle of the cantilevel 61 links jointly on the undercarriage 7. The undercarriage 7 has handrail 71 and instrument panel 71.

[0047] Optimum proposal, the elastic expansion assembly 62 consists of conducting rod 62a, one side of the conducting rod 62a links jointly with cantilever 61, and the other side goes through the undercarriage 7, and in the front of this side, there is an elastic barrier 62b in the undercarriage 7. The elastic expansion assembly can also be spring, with the usage of the spring, it can lessen the shock. In the next place, the cantilever 61 shows in the L-form, and in the corner of the cantilever 61 links jointly on the undercarriage 7, and the length of one side of the cantilever 61 which links with the rack 1 is more than the length of the other side of the elastic expansion assembly 62.

[0048] Ulteriorly, the running rack in this example includes frame 11, in the front of the downward of the frame 11, there is a cantilever shelving 12, the cantilever we said above links jointly with the front of the cantilever Alvin 12, and between the above undercarriage and the middle of running rack, there is damping cylinder 13, and one side of it stalls strongly with the undercarriage, and the other side links strongly with the running rack.

[0049] There is a elastic buffer structure between the running zone plate and the frame 11; this elastic buffer structure includes quite a few settings between the two sides of the frame 11, and it locates the elastic buffer 8 between the frame 11 and the running rack, and the elastic buffer 8 stalls one by one. The elastic buffer structure can increase shock absorption to the backward of the running rack, and it enables every position of the running rack achieve the shock absorption. The elastic buffer 8 stalls separately on the two sides of the frame 11, and they stall one by one.

[0050] The elastic buffer 8 consists of the first shaped clamp 81 and the second shaped clamp 82 in the upper and downward side, the above first shaped clamp 81 links with the broadside of running rack, and the above second shaped clamp 82 stalls steadily on the broadside of the frame 11, and between the above first shaped clamp 81 and the second shaped clamp 82, there stalls quite a few buffer springs 83. When the running board gains a force from the downward, the buffer springs can provide counter force in upper side, and it can obtain the effect of cushioning shock absorption.

Example 2

[0051] As it shows in picture 8, the structure in this example is the same as the example 1, while the difference is: tubular motor 4 is inner rotor tubular motor which includes inner rotor 43 and outer stator 44, the above outer stator 44 links steadily with running rack 1, in the periphery of the outer stator 44, there stalls tubulose shape 45 with the outer stator 44, the above tubulose shape 45 and the inner rotor 43 links with each other, and the inner rotor 43 can activate the tubulose shape 45, the above round running band 2 is around the periphery of the tubulose shape 45.
