[0023] Figure 1 This is a schematic diagram of the overall structure of a non-powered treadmill 10 provided in one embodiment of the present application. Figure 2 A schematic structural diagram of a non-powered treadmill 10 provided in one embodiment of the present application at one viewing angle.

[0024] See also Figure 1 and Figure 2 An embodiment of the present application provides a non-powered treadmill 10 , which includes a body 100 , a motion mechanism 200 and a belt mechanism 300 .

[0025] The body 100 is a fixed component in the non-powered treadmill 10, and is used to install, position, and connect other components or assemblies in the non-powered treadmill 10, such as the motion mechanism 200, the belt mechanism 300, etc. The structure, shape, and size of the body 100 are not limited, and can be flexibly adjusted according to the design requirements of the non-powered treadmill 10.

[0026] The motion mechanism 200 includes a swing rod 210, a crank 220, a roller 230, and a first roller 240. The swing rod 210 is rotatably connected to the body 100, and has a movable end 211 and a fixed end 212 opposite to each other. The movable end 211 and the fixed end 212 are divided according to the different states of the two ends of the swing rod 210 when the motion structure is in motion, that is, when the motion structure is in motion, one end of the swing rod 210 can move within a certain range because it is not connected to other components, and is in a state with a relatively large range of motion, so this end of the swing rod 210 is called the movable end 211, and the other end of the swing rod 210 is connected to other components or assemblies in the motion mechanism 200, and its movement is restricted to a certain extent, and is in a state with a relatively small range of motion, so this end of the swing rod 210 is called the fixed end 212. The movable end 211 and the fixed end 212 only differ in the motion state, which does not mean that there is a difference in the structure of the movable end 211 and the fixed end 212. The connection between the swing rod 210 and the body 100 is located between the movable end 211 and the fixed end 212. The connection position here is not necessarily the midpoint between the movable end 211 and the fixed end 212 on the swing rod 210. The connection position can be closer to the movable end 211 or the fixed end 212, that is, the connection position can be flexibly adjusted according to the actual movement of the swing rod 210, which is not limited here. When in use, the user can drive the movable end 211 of the swing rod 210 to move in one direction, and the swing rod 210 swings relative to the body 100 around the connection position with the body 100, thereby driving the fixed end 212 of the swing rod 210 to move in another direction.

[0027] The fixed end 212 of the swing rod 210 is rotationally connected to one end of the crank 220, and the other end of the crank 220 is rotationally connected to the body 100 via the roller 230. When the swing rod 210 swings relative to the body 100, the crank 220 can be driven to move. By reasonably setting the size of the crank 220 to change its rotation radius, the crank 220 can be made to rotate around the body 100 as a whole. At the same time, the roller 230 is rotationally connected to the body 100, and the roller 230 is rotationally connected to the other end of the crank 220 around its axis. The swing rod 210 is configured to drive the roller 230 to rotate via the crank 220 when swinging. That is, during the movement of the motion structure, the end of the crank 220 connected to the swing rod 210 performs a rotational motion with the end of the crank 220 connected to the roller 230 as the center, so the crank 220 can drive the roller 230 to rotate under the drive of the swing rod 210. Thus, the user can use both hands to push the swing rod 210 to swing and perform hand movements. The first roller 240 is sleeved outside the roller 230. When the roller 230 rotates, the first roller 240 can rotate synchronously with the roller 230 or relatively independently with the roller 230 under different connection modes.

[0028] The belt mechanism 300 includes a driving wheel 310 and a driven wheel 320 which are respectively connected to the machine body 100 and arranged opposite to each other, and a synchronous belt 330 which is sleeved on the driving wheel 310 and the driven wheel 320. The rotation of the driving wheel 310 can drive the synchronous belt 330 to move along the driving wheel 310, thereby driving the driven wheel to rotate. Among them, the first roller 240 is configured to be able to drive the driving wheel 310 to rotate or the first roller 240 is configured as the driving wheel 310. When in use, when the first roller 240 rotates synchronously with the roller 230, a transmission device such as a transmission belt, a transmission gear, etc. is used to connect the first roller 240 with the driving wheel 310, and the first roller 240 can drive the driving wheel 310 to rotate, thereby driving the synchronous belt 330 to move. Or the first roller 240 is used as the driving wheel 310, and the first roller 240 can directly drive the synchronous belt 330 to move. At this time, the user can run in the opposite direction of the synchronous belt 330 to keep himself on the synchronous belt 330 and not be dragged away by the movement of the synchronous belt 330. When the first roller 240 rotates relatively independently from the roller 230, that is, the first roller 240 does not rotate synchronously with the roller 230, the user needs to use the friction force during running to drive the synchronous belt 330 to move.

[0029] The non-powered treadmill 10 according to the embodiment of the present application is not only provided with a belt mechanism 300, so that the user can normally run on the synchronous belt 330, but also provided with a motion mechanism 200 on the body 100, and the swing rod 210 in the motion mechanism 200 is rotatably connected with the body 100, so that the user can use both hands to push the swing rod 210 to swing while running, and perform two kinds of exercise at the same time, which is more functional and can meet the diversified needs of the user. Moreover, the swing rod 210 in the motion mechanism 200 can drive the roller 230 to rotate via the crank 220 when swinging, and the first roller 240 disposed outside the roller 230 can drive the driving wheel 310 in the belt mechanism 300 to rotate or serve as the driving wheel 310 in the belt mechanism 300, so that the number of components in the non-powered treadmill 10 is reduced, the compactness of the structure of the non-powered treadmill 10 is improved, and its space occupation is reduced, and the running exercise and hand exercise of the user have a linkage effect, which improves the user's exercise experience.

[0030] Specifically, in some embodiments, the unpowered treadmill 10 further includes a one-way bearing, the inner ring of the one-way bearing is sleeved on the roller 230, and the first roller 240 is sleeved on the outer ring of the one-way bearing. The rolling seat of the one-way bearing contains a lot of rollers 230, needle rollers or balls, and the shape of its rolling seat makes it roll only in one direction, and generates a lot of resistance in the other direction. Therefore, the one-way bearing is a kind of bearing that can rotate freely in one direction and is locked in the other direction. The rotation direction of the roller 230 is made to coincide with the locking direction of the one-way bearing, so that when the roller 230 rotates, a lot of resistance will be generated between the outer ring and the inner ring of the one-way bearing and it cannot rotate. Under the action of this resistance, the one-way bearing can drive the first roller 240 to rotate, so that the first roller 240 and the roller 230 can rotate synchronously, and then the synchronous belt 330 is driven to move through the first roller 240. At this time, the user can drive the crank 220 to rotate by pushing the rocker arm 210, and the crank 220 also drives the roller 230 to rotate, and the roller 230 further drives the first roller 240 to rotate. Under the action of the first roller 240, the synchronous belt 330 also moves accordingly, and the user can run while performing hand exercises.

[0031] Different from the situation in the previous embodiment, in some other embodiments, the non-powered treadmill 10 also includes a universal bearing, the inner ring of the universal bearing is sleeved on the roller 230, and the first roller 240 is sleeved on the outer ring of the universal bearing. The rolling seat of the universal bearing contains many rollers 230, needle rollers or balls, and the shape of its rolling seat enables it to roll in various directions. Therefore, the universal bearing is a kind of bearing that can rotate freely in both directions. Regardless of the rotation direction of the roller 230, when the roller 230 rotates, the roller 230 will drive the inner ring of the universal bearing to rotate, and the inner ring and the outer ring of the universal bearing will also rotate relative to each other, then the first roller 240 sleeved on the outer ring will not rotate synchronously with the roller 230. At this time, the user can drive the crank 220 to rotate by pushing the swing rod 210, and the crank 220 also drives the roller 230 to rotate, but the roller 230 will not drive the first roller 240 to rotate. The movement between the synchronous belt 330 and the swing rod 210 is independent, and the user still needs to drive the treadmill belt to move through his own running movements.

[0032] Figure 3 for Figure 1 A local enlarged schematic diagram of point A in the middle.

[0033] Please combine Figure 1 and Figure 2 Also see Figure 3 In order to allow the user to more conveniently push the swing rod 210 to swing along the body 100, in some embodiments, the motion mechanism 200 further includes a handlebar 250, and a receiving groove 2111 is provided on the movable end 211 along the length direction of the swing rod 210, and one end of the handlebar 250 is received in the receiving groove 2111. The handlebar 250 can be made into a shape and size that is convenient for human hands to hold, and a gripping portion that is convenient for users to hold can also be provided on the handlebar 250. The user holds the handlebar 250 and pushes the handlebar 250 to move, and since the handlebar 250 is received in the receiving groove 2111 provided on the movable end 211 along the length direction of the swing rod 210, the handlebar 250 can drive the swing rod 210 to move. In addition, the length of the handlebar 250 is adjustable for different users, so that the handlebar 250 is at a height that is convenient for users to hold, and is convenient for users to use.

[0034] In some embodiments, the movable end 211 is further provided with a fixing member 2112, on which a slot 2113 is provided, and a clamping member 251 matching the slot 2113 is protruding from the handlebar 250, and the clamping member 251 is configured to be clamped with the slot 2113 to fix the handlebar 250. In this way, the handlebar 250 can be firmly fixed to the movable end 211 by the clamping member 251 on the handlebar 250 and the slot 2113 on the fixing member 2112 of the movable end 211, so as to avoid the handlebar 250 and the swing rod 210 from being separated during use, thereby ensuring the safety of the user. The shape, size, etc. of the fixing member 2112, the slot 2113 and the clamping member 251 are not limited, and it is sufficient that the clamping member 251 can be well clamped with the slot 2113 to fix the handlebar 250.

[0035] Figure 4 This is a schematic diagram of the connection relationship between the handlebar 250 and the fixing member 2112 in one embodiment of the present application. Figure 5 This is a cross-sectional view of the connection relationship between the handlebar rod 250 and the fixing member 2112 in one embodiment of the present application.

[0036] See also Figure 4 and Figure 5 On the basis of the above embodiment, a plurality of slots 2113 are provided on the fixing member 2112, and each slot 2113 is arranged at intervals along a direction inclined to the length direction of the swing rod 210, and the clamping member 251 is configured to be able to clamp with each slot 2113 to adjust the fixing angle of the handle bar 250. The plurality of slots 2113 on the fixing member 2112 are arranged at intervals along a direction inclined to the length direction of the swing rod 210, and when the handle bar 250 is adjusted to be clamped with each slot 2113, from the user's perspective, the handle bar 250 is expanded or retracted relative to the user's own hands. Since during the use of the non-powered treadmill 10, in order to facilitate the operation with both hands, each component in the motion mechanism 200 usually has two sets, and the two sets of components are respectively arranged on both sides of the body 100, so as to be operated by the user's hands respectively, the user can adjust the outward expansion or inward contraction of the handlebars 250 to make the distance between the two handlebars 250 match the distance between his / her own arms, that is, the shoulder width, so that it can better fit his / her body structure during exercise and ensure the comfort of the exercise process. In addition, when the non-powered treadmill 10 is not in use, the distance between the two handlebars 250 can be adjusted to be as small as possible to reduce the space occupied by the non-powered treadmill 10 as a whole, so as to facilitate carrying and storage.

[0037] The clamping member 251 and the slot 2113 are mutually clamped, and when in use, the clamping member 251 may often need to be adjusted to be clamped with different slots 2113. In order to facilitate the clamping and separation between the clamping member 251 and the slot 2113, in some embodiments, one end of the clamping member 251 protrudes from the handlebar rod 250, and the other end of the clamping member 251 is connected to the handlebar rod 250 through the elastic member 252. With this structure, after the clamping member 251 is clamped with the slot 2113, under the elastic force of the elastic member 252, the clamping member 251 can always abut against the inside of the slot 2113, thereby ensuring the clamping tightness of the clamping member 251 and the slot 2113. When the clamping member 251 needs to be separated from the slot 2113, it is only necessary to press the clamping member 251 so that the clamping member 251 compresses the elastic member 252 inwardly, and the clamping member 251 will be disengaged from the slot 2113 and separated from the slot 2113. At this time, after adjusting the handlebar 250 or the fixing member 2112 so that the clamping member 251 is aligned with the new slot 2113, the clamping member 251 is released, and the clamping member 251 enters the new slot 2113 under the elastic force of the elastic member 252 and is clamped therewith. The process of clamping and disassembling is simple and convenient. In some embodiments, the elastic member 252 can be a spring.

[0038] In order to make the structure of the body 100 more stable and to better connect and support other components in the non-powered treadmill 10, in one embodiment, the body 100 includes a fixed frame 110 and a column 120 inclined to the fixed frame 110, the swing arm 210 is rotatably connected to the column 120, the driving wheel 310 and the driven wheel 320 are respectively rotatably connected to the two ends of the fixed frame 110, and the roller 230 is rotatably connected to the fixed frame 110.

[0039] Furthermore, in order to make the position of the swing rod 210 in the motion structure more reasonable and convenient for the user to operate, in some embodiments, the body 100 further includes a connecting rod 130, one end of the connecting rod 130 is rotatably connected to the position between the movable end 211 and the fixed end 212 of the swing rod 210, and the other end of the connecting rod 130 is rotatably connected to the column 120. By adjusting the length of the connecting rod 130, the specific position of the swing rod 210 on the body 100 can be changed.

[0040] In one embodiment, the motion mechanism 200 further includes a second roller 260 and a flywheel 270. The second roller 260 is sleeved outside the roller 230. The flywheel 270 is rotatably connected to the body 100. The second roller 260 is configured to drive the flywheel 270 to rotate. As described above, the inner ring of the one-way bearing can be sleeved on the roller 230, and the second roller 260 is sleeved on the outer ring of the one-way bearing. In this way, when the roller 230 rotates, it can drive the second roller 260 to rotate. The second roller 260 further drives the flywheel 270 to rotate. The flywheel 270 can store energy and inertia during the rotation of the roller 230. The flywheel 270 has a large moment of inertia. Since the process of the user pushing the swing rod 210 to move is discontinuous, the process of the swing rod 210 driving the roller 230 to rotate is also discontinuous, so the rotation speed of the roller 230 is also variable. When the rotation speed of the roller 230 increases, the kinetic energy of the flywheel 270 increases, and the energy is stored; when the rotation speed of the roller 230 decreases, the kinetic energy of the flywheel 270 decreases, and the energy is released. Accordingly, the flywheel 270 can be used to reduce the speed fluctuation of the roller 230 during rotation, so that the rotation of the roller 230 remains uniform and has a certain degree of continuity, thereby improving the user's experience.

[0041] In summary, the non-powered treadmill 10 in the present application can meet the diversified needs of users, which not only reduces the number of components in the non-powered treadmill 10, improves the compactness of the structure of the non-powered treadmill 10, reduces its space occupancy, but also enables the user's running movement and hand movement to have a linkage effect, thereby improving the user's exercise experience.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
