[0046] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example

[0047] See also Figure 1-Figure 7 A walking machine includes a treadmill frame 1, an active roller 11 installed at the front end of the treadmill frame 1, a driven roller 12 installed at the rear end of the treadmill frame 1, and a running belt 13 wound around the active roller 11 and the driven roller 12, wherein the active roller 11 and the driven roller 12 can both rotate relative to the treadmill frame 1 to drive the running belt 13 to circumferentially circulate during the rotation of the active roller 11.

[0048] The active roller 11 and the driven roller 12 can be directly rotatably mounted on the treadmill frame 1 , or corresponding long shafts can be mounted on the treadmill frame 1 , and the active roller 11 and the driven roller 12 can be rotatably mounted on the corresponding long shafts.

[0049] The treadmill frame 1 includes at least two side rods distributed on the left and right. In this embodiment, corresponding improvements are made to one of the side rods. Specifically, the side rod includes a first rod 14, a motor frame 2, and a second rod 15. The motor frame 2 is arranged between the first rod 14 and the second rod 15 and is fixedly connected to the two respectively, that is, the first rod 14, the motor frame 2, and the second rod 15 are fixedly connected in sequence.

[0050] It can be understood that, compared with the prior art, part of the side rods of the treadmill frame 1 is removed and replaced by the motor frame 2 , thereby providing additional arrangement space for the motor 3 .

[0051] like Figure 7 、 Figure 12 、 Figure 18 As shown, in order to make the first rod 14 and the second rod 15 fit more tightly with the motor frame 2, the end of the first rod 14 facing the motor frame 2 and the end of the second rod 15 facing the motor frame 2 can be designed to be compatible with the outer wall of the motor frame 2. If the outer wall of the motor frame 2 is designed to be circular, the shapes of the corresponding ends of the first rod 14 and the second rod 15 can be designed to be arc-shaped.

[0052] As one of the implementation methods, Figure 7 、 Figure 12 、 Figure 18 As shown, the horizontal height of the upper edge of the first rod 14 is higher than the horizontal height of the upper edge of the second rod 15, so as to increase the height of the parts provided on the first rod 14 from the ground, including the active roller 11 and the like.

[0053] As one embodiment, the first rod 14, the motor frame 2 and the second rod 15 can be fixed by welding or directly integrally formed.

[0054] The motor 3 is installed in the motor frame 2. The motor 3 serves as a power source and is transmission-connected to the active roller 11. That is, after the motor 3 is started, it can drive the active roller 11 to rotate.

[0055] In this embodiment, both ends of the motor 3 are fixed by the motor frame 2, and a transmission belt 4 or chain is passed between the motor 3 and the active roller 11 to form a transmission cooperation relationship (one-stage reduction) between the two. The motor 3 is an outer rotor motor.

[0056] Specifically, the motor frame 2 includes a first limiting wall 21 for positioning one end of the motor 3 and a second limiting wall 22 for positioning the other end of the motor 3. The first limiting wall 21 is detachable and serves as an inlet and outlet for disassembly and assembly of the motor 3 at this end of the motor frame 2. The second limiting wall 22 can be integrally formed on the main body of the motor frame 2.

[0057] As one of the implementation methods, Figure 2As shown, extension columns 16 are respectively fixed on the outer walls of the first rod 14 and the second rod 15, and the two extension columns 16 are respectively arranged on both sides of the motor frame 2. Correspondingly, mounting holes 211 are respectively opened at both ends of the first limiting wall 21, so that the first limiting wall 21 is positioned in a manner such that fasteners and other components pass through the mounting holes 211 and are positioned on the extension columns 16, such as bolts passing through the mounting holes 211 and being threadedly connected with the threaded holes on the extension columns 16 to lock the first limiting wall 21. Of course, the overall length of the first limiting wall 21 needs to be greater than the width of the motor frame 2 so that the mounting holes 211 can be aligned with the threaded holes on the extension columns 16.

[0058] On the motor frame 2, one end of the second limiting wall 22 is located, such as Figure 5 As shown, a first opening 23 is provided on the motor frame 2 at one side of the second limiting wall 22. The first opening 23 is used to provide the required space for the movement of the transmission belt 4 or chain, that is, the transmission belt 4 or chain enters the output shaft located in the motor frame 2 through the first opening 23, and the solid line shows the transmission coordination between the two.

[0059] A support platform 24 is provided on the motor frame 2 at the other side of the second limiting wall 22. The support platform 24 is used to support the treadmill running board 5 to further improve the installation stability of the treadmill running board 5. Specifically, the end corner 51 of the treadmill running board 5 is located on the support platform 24.

[0060] Furthermore, a hole is opened on the support platform 24, and a corresponding hole is opened on the end corner 51 of the treadmill running board 5, so that the end corner 51 of the treadmill running board 5 can be locked to the support platform 24 by fasteners, thereby further improving the installation stability of the treadmill running board 5.

[0061] In order to facilitate the cooperation between the end corner 51 of the treadmill running board 5 and the support platform 24, in this embodiment, an escape opening 25 for evading the treadmill running board 5 is opened on the motor frame 2 at the other side of the second limiting wall 22, that is, above the support platform 24. Figure 5 shown.

[0062] Regarding the treadmill running board 5, in this embodiment, the treadmill running board 5 is provided with one or more avoidance gaps 52 at one end thereof close to the motor frame 2 for avoiding the motor frame 2, the motor output end, the transmission belt 4 or the chain, such as Figure 6 In one embodiment, two avoidance gaps 52 are provided, and after the gaps are provided, the end corners 51 of the treadmill deck 5 are formed.

[0063] In this embodiment, a limiting hole 26 for positioning the end of the motor 3 is respectively formed on the first limiting wall 21 and the second limiting wall 22. The limiting hole 26 is non-circular in shape so that the part of the outer rotor motor can be locked without affecting the normal rotation of its outer rotor.

[0064] In this embodiment, a third transmission wheel 41 connected to the transmission belt 4 or chain is fixed on the active roller 11 . The outer diameter of the third transmission wheel 41 is larger than the outer diameters of the active roller 11 and the output shaft of the motor 3 . Example

[0065] Compared with Example 1, this embodiment is different in that Example 1 is a one-stage deceleration, while Example 2 is a two-stage or above deceleration, and the rest are the same or similar.

[0066] See also Figures 8-12 As shown, a transmission shaft 6 is installed on the first rod 14 or the motor frame 2, and the output shaft of the motor 3 is connected to the transmission shaft 6 through a transmission belt 4 or a chain. This is the first stage of deceleration; the transmission shaft 6 is connected to the active roller 11 through a transmission belt 4 or a chain. This is the second stage of deceleration. If more stages of deceleration are required, further transmission shafts can be added. The additional transmission shafts can be installed on the first rod 14 or the motor frame 2 according to actual needs. Of course, according to the actual number of stages of deceleration, the size of the avoidance gap of the running board and the shape and size of the motor frame will vary accordingly according to actual needs.

[0067] In this embodiment, the motor 3 is connected to the active roller 11 after two or more decelerations, so that the active roller 11 rotates accordingly. For the form of setting the third transmission wheel 41 on the active roller 11, please refer to the description in Example 1.

[0068] The transmission shaft 6 can be rotatably arranged on the first rod 14 or the motor frame 2, or can be fixed on the first rod 14 or the motor frame 2, and a first transmission wheel 61 connected to the output shaft of the motor 3 and a second transmission wheel 62 connected to the active roller 11 are rotatably arranged on the transmission shaft 6.

[0069] As one embodiment, the outer diameter of the first transmission wheel 61 is greater than the outer diameter of the second transmission wheel 62 .

[0070] like Figure 2 、 Figure 3 The figure shows one of the styles of motor frame design, which can be used for at least two-stage deceleration, and the shape of the ends of the first rod 14 and the second rod 15 facing the motor frame 2 is determined by the shape of the outer wall of the motor frame 2. If the corresponding outer wall of the motor frame 2 is a flat wall, the shape of the ends of the first rod 14 and the second rod 15 facing the motor frame 2 is also flat, as shown in FIG. Figure 12 One option is shown. Example

[0071] Compared with Example 1, this embodiment differs in that: in Example 1, both ends of the motor are fixed by the motor frame (two-end fixed); in this embodiment, only one end of the motor is fixed by the motor frame (single-end fixed), and the inlet and outlet positions of the motor are different, while the rest are the same.

[0072] See also Figures 13-18 As shown, the motor frame 2 includes a main frame body 27 fixedly connected to the first rod 14 and the second rod 15, and a first limiting wall 21 fixed on the main frame body 27. One or more first fasteners 28 are arranged on the first limiting wall 21. One end of the motor 3 includes one or more matching holes 31 for matching with the first fastener 28, so that the motor 3 can be positioned at the first limiting wall 21 through the first fastener 28.

[0073] As one option, the number of the first fasteners 28 and the number of the matching holes 31 can be set to four, and they are evenly distributed in the circumferential direction.

[0074] In this embodiment, the matching hole 31 may be a threaded hole. The first fastener 28 is threadedly connected to the matching hole 31 after passing through the hole on the first limiting wall 21 , thereby locking the position of the motor 3 .

[0075] An opening is formed at the inner end of the main frame 27 and communicates with the internal cavity thereof. The opening serves as an inlet and outlet for the motor 3 . The motor 3 enters the main frame 27 through the opening and is then locked by the first fastener 28 .

[0076] In this embodiment, the output shaft of the motor 3 extends out of the opening and is connected to the transmission belt 4 or chain, so as to be transmission-connected to the active roller 11 through the transmission belt 4 or chain.

[0077] In this embodiment, it can be designed as a single-stage deceleration as mentioned in Example 1, or it can be designed as a two-stage or above deceleration as mentioned in Example 2. For the specific details of the deceleration transmission part, please refer to Examples 1 and 2, and no further details will be given.

[0078] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
