However, for a treadmill with a foot pad structure, the body of the treadmill is generally designed to be a foldable structure or the armrest of the treadmill is designed to be a foldable structure. Although the occupied space can be reduced to a certain extent after folding, the overall structure of the treadmill is irregular and there is a problem of protruding foot pads, which will cause the packaging size of the treadmill to be too large and inconvenient to pack.

[0004] Therefore, it is necessary to provide a new technical solution to improve one or more problems existing in the above solutions.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] The purpose of the embodiments of the present disclosure is to provide a treadmill, which is easy to fold and has a regular overall structure and a small size after folding, so it is easy to pack.

[0007] According to an embodiment of the present disclosure, there is provided a treadmill, comprising:

[0008] The frame body comprises a first frame, a second frame and an axle pin assembly, wherein the first frame and the second frame are rotatably connected via the axle pin assembly so that the frame body can be switched between an unfolded state and a folded state;

[0009] A running board module, comprising a first running board and a second running board, wherein the first running board is arranged on the first frame, and the second running board is arranged on the second frame;

[0011] A foot pad module, comprising a first foot pad and a second foot pad, wherein the first foot pad is disposed on the first frame, and the second foot pad is rotatably disposed on the second frame and can be switched between a supporting state and a storage state;

[0012] Wherein, when the frame is in an unfolded state, the first running board and the second running board are located in the same plane, and the second foot pad can be in a supporting state to support the second frame; when the frame is in a folded state, the second running board can be stored on the first running board, and the second foot pad can be in a stored state to be stored inside the second frame.

[0013] The technical solution provided by the present disclosure may have the following beneficial effects:

[0014] In the embodiments of the present disclosure, on the one hand, the first frame and the second frame are rotatably connected through the axle pin assembly, so that the frame can be switched between the unfolded state and the folded state, so that the treadmill can be unfolded and folded. After the frame of the treadmill is unfolded, a running platform can be provided to the user through the cooperation of the frame, the running board module, the running belt and the driving module. After the frame of the treadmill is folded, the space occupied by the treadmill can be reduced, which is convenient for users to store and transport.

[0071] Furthermore, the first axle pin connector 132 includes a first connecting plate 1321 and a first axle pin sleeve, the first connecting plate 1321 is disposed on the first frame 110, the first axle pin sleeve is connected to the first connecting plate 1321, and is fixedly sleeved on the axle pin body 131;

[0072] The second axle pin connector 133 includes a second connecting plate 1331 and a second axle pin sleeve 1332 . The second connecting plate 1331 is disposed on the second frame 120 . The second axle pin sleeve 1332 is connected to the second connecting plate 1331 and is rotatably sleeved on the axle pin body 131 .

[0073] When the frame 100 is in the unfolded state, the first connecting plate 1321 and the second connecting plate 1331 are located between the first frame 110 and the second frame 120, and the first connecting plate 1321 and the second connecting plate 1331 are abutted against each other; when the frame 100 is in the folded state, the first connecting plate 1321 and the second connecting plate 1331 are spaced and arranged relatively along the height direction of the treadmill.

[0074] For example, the first bracket 111 and the second bracket 112 of the first frame 110 are each provided with a first connecting plate 1321 at one end facing the second frame 120, and the third bracket 121 and the fourth bracket 122 of the second frame 120 are each provided with a second connecting plate 1331 at one end facing the first frame 110, a first axle pin sleeve of the first connecting plate 1321 on the first bracket 111 and a second axle pin sleeve 1332 of the second connecting plate 1331 on the third bracket 121 are rotationally connected via an axle pin body 131, and a first axle pin sleeve of the first connecting plate 1321 on the second bracket 112 and a second axle pin sleeve 1332 of the second connecting plate 1331 on the fourth bracket 122 are rotationally connected via another axle pin body 131, thereby realizing the rotational connection of the first frame 110 and the second frame 120 through two axle pin assemblies 130.

[0079] The structural design of the shaft pin body 131 not only ensures that the shaft pin body 131 is firmly connected with the first shaft pin sleeve 1332 , but also can reduce the volume of the shaft pin body 131 as much as possible.

[0080] For example, one end of the third shaft 1312 away from the second shaft 1311 is threadedly connected with a fastener, and when the fastener is fastened to the third shaft 1312 , the fastener abuts against the second ring 1323 .

[0081] For example, a threaded hole 1310 is formed at one end of the third shaft 1312 away from the second shaft 1311 , and the first fastener 134 is threadedly connected to the threaded hole 1310 , so as to facilitate the inspection and replacement of parts of the shaft pin assembly 130 .

[0082] Furthermore, a washer 135 is sleeved on the first fastener 134, and when the first fastener 134 is fastened to the third shaft 1312, the washer 135 abuts against the third shaft 1312 and the second sleeve ring 1323. Further, by providing the washer 135 structure, the fastening effect of the first fastener 134 can be improved, and at the same time, when the first fastener 134 is fastened, the surface of the second sleeve ring 1323 and the third shaft 1312 can be prevented from being scratched.

[0083] Optionally, the outer diameters of the first collar 1322, the second collar 1323, and the second shaft pin sleeve 1332 are all the same as the outer diameter of the second shaft body 1311. By limiting the size of the first collar 1322, the second collar 1323, and the second shaft pin sleeve 1332, the outer circumference of the second shaft body 1311 is kept flush with the outer circumference of the first collar 1322, the second collar 1323, and the second shaft pin sleeve 1332, and there is no protrusion on the entire shaft pin body 131, thereby improving safety and aesthetics.

[0084] In one embodiment, reference Figure 3 and Figure 4 ,as well as Figures 11 to 13As shown in , the shaft pin body 131 protrudes from the upper surface of the frame body 100, the first frame 110 is provided with a first side bar 117, the first side bar 117 is provided with a first plug-in structure, the second frame 120 is provided with a second side bar 125, and the second side bar 125 is provided with a second plug-in structure;

[0085] Among them, when the frame 100 is in the unfolded state, along the front-to-back direction of the treadmill, the first side strip 117 and the second side strip 125 are located on both sides of the axle pin body 131, and the axle pin body 131 is accommodated in the gap between the first side strip 117 and the second side strip 125; when the frame 100 is in the folded state, along the height direction of the treadmill, the first side strip 117 and the second side strip 125 are located between the first frame 110 and the second frame 120, and the first pair of plug-in structures and the second pair of plug-in structures are plug-in connected.

[0086] With regard to the axle pin body 131 protruding from the upper surface of the frame 100, the present embodiment respectively sets a first side strip 117 and a second side strip 125 on the first frame 110 and the second frame 120, so that when the frame 100 is in the unfolded state, the first side strip 117 and the second side strip 125 arranged on both sides of the axle pin body 131 can be used to hide the axle pin body 131, thereby preventing the axle pin body 131 from protruding from the frame 100, thereby improving the safety of the user when using the treadmill; and further, by respectively setting a first pair of plug-in structures on the first side strip 117 and a second pair of plug-in structures on the second side strip 125, the first pair of plug-in structures and the second pair of plug-in structures can be used for plug-in connection, so that when the frame 100 is in the folded state, the first frame 110 and the second frame 120 are tightly closed, so that the treadmill can be tightly closed after being folded.

[0087] For example, the first bracket 111 and the second bracket 112 of the first frame 110 are both provided with a first side strip 117, and the third bracket 121 and the fourth bracket 122 of the second frame 120 are both provided with a second side strip 125, wherein the first side strip 117 and the second side strip 125 both extend along the length direction of the treadmill to ensure that when the frame 100 is in the unfolded state, the degree to which the axle pin body 131 arranged on the upper surfaces of both sides of the frame 100 protrudes from the frame 100 is reduced, and at the same time, when the frame 100 is in the folded state, the first frame 110 and the second frame 120 are tightly closed.

[0088] Optionally, along the height direction of the treadmill, the upper edge of the first pair of plug-in structures on the first side strip 117, the upper edge of the second pair of plug-in structures on the second side strip 125, and the upper edge of the axle pin body 131 can be set to be flush, so that when the frame 100 is in the unfolded state, the axle pin body 131 is hidden between the first side strip 117 and the second side strip 125 and will not cause harm to the user.

[0089] Furthermore, the first pair of plug-in structures includes a plurality of first racks 1171 spaced apart on the first side strip 117, and the second pair of plug-in structures includes a plurality of second racks 1251 spaced apart on the second side strip 125; when the frame 100 is in a folded state, each of the second racks 1251 on the second side strip 125 is correspondingly accommodated between two adjacent first racks 1171 on the first side strip 117.

[0090] Through the specific structural arrangement of the first plug-in structure and the second plug-in structure, when the frame 100 is in a folded state, the first side bar 117 and the second side bar 125 can be tightly plugged together by using a plurality of first racks 1171 and a plurality of second racks 1251, thereby ensuring that the first frame 110 and the second frame 120 are tightly closed.

[0091] Optionally, along the direction away from the first side bar 117 , the size of the first rack 1171 in the width direction of the frame 100 gradually decreases; along the direction away from the second side bar 125 , the size of the second rack 1251 in the width direction of the frame 100 gradually decreases.

[0092] By limiting the sizes of the first rack 1171 and the second rack 1251 as mentioned above, the projection of the first rack 1171 in the front-to-rear direction of the treadmill in a direction away from the first side bar 117 is gradually reduced, and the projection of the second rack 1251 in the front-to-rear direction of the treadmill in a direction away from the second side bar 125 is gradually reduced. This shape setting makes the first and second plug-in structures encounter appropriate resistance during the plug-in process, and the first rack 1171 and the second rack 1251 fit each other in an inclined form, so that the first and second plug-in structures are tightly plugged in.

[0093] Optionally, the surface of the first rack 1171 away from the first side bar 117 is an arcuate surface, and the surface of the second rack 1251 away from the second side bar 125 is an arcuate surface. The arcuate surface arrangement on the first rack 1171 and the arcuate surface arrangement on the second rack 1251 can, on the one hand, prevent the first plug-in structure and the second plug-in structure from damaging each other during the plug-in process, and on the other hand, make the first plug-in structure and the second plug-in structure receive appropriate resistance during the plug-in process.

[0094] Further, the first running board 210 may be embedded in the first frame 110, and the second running board 220 may be embedded in the second frame 120.

[0096] A second protrusion 1252 is disposed on a surface of the second side bar 125 away from the second rack 1251 , and the second protrusion 1252 is locked in the second slit 1201 .

[0097] The above-mentioned method further provides a first convex strip 1172 on the first side strip 117, and utilizes the first convex strip 1172 to engage with the first gap 1101 to improve the connection stability between the first side strip 117 and the first frame 110, thereby preventing the first side strip 117 from shifting after long-term use; further provides a second convex strip 1252 on the second side strip 125, and utilizes the second convex strip 1252 to engage with the second gap 1201 to improve the connection stability between the second side strip 125 and the second frame 120, thereby preventing the second side strip 125 from shifting after long-term use.

[0098] It should be noted that the first gap 1101 can be understood as: the gap formed between the first bracket 111 and the first running board 210, and the gap formed between the second bracket 112 and the first running board 210, along the width direction of the treadmill. It should be noted that the second gap 1201 can be understood as: the gap formed between the third bracket 121 and the second running board 220, and the gap formed between the fourth bracket 122 and the second running board 220, along the width direction of the treadmill.

[0108] By configuring the first metal member 211 and the second metal member 221, when the frame 100 is in the unfolded state, the first metal member 211 and the second metal member 221 between the first running board 210 and the second running board 220 are in contact with each other, thereby reducing the gap at the connection between the first running board 210 and the second running board 220, thereby avoiding the noise generated by the user's movement at the connection between the first running board 210 and the second running board 220, thereby improving the user's experience. On the other hand, the first metal member 211 located on the upper surface of the first running board 210 and the second metal member 221 located on the upper surface of the second running board 220 can improve the smoothness between the running belt 300 and the first running board 210 and the second running board 220, thereby reducing the friction between the running belt 300 and the first running board 210 and the second running board 220, thereby further improving the user's experience.

[0109] It should be noted that the surfaces of the first metal member 211 and the second metal member 221 used in this embodiment are smooth, which can better reduce the friction between the treadbelt 300 and the first running deck 210 , and between the treadbelt 300 and the second running deck 220 .

[0110] Furthermore, the first metal member 211 includes a first horizontal portion 2111 and a first vertical portion 2112 which are vertically connected, the first horizontal portion 2111 is disposed on the upper surface of the first running board 210, and the first vertical portion 2112 is disposed on the end surface of the first running board 210;

[0114] The second horizontal portion 2211 completely covers the upper surface of the second running deck 220, and the second vertical portion 2212 completely covers or semi-covers the end surface of the second running deck 220 close to the first running deck 210; wherein, along the width direction of the treadmill, the length of the second vertical portion 2212 is equal to the width of the second running deck 220.

[0115] By designing that the first horizontal portion 2111 of the first metal member 211 completely covers the upper surface of the first running board 210, and the second horizontal portion 2211 of the second metal member 221 completely covers the upper surface of the second running board 220, the friction between the running belt 300 and the first horizontal portion 2111 of the first metal member 211, and between the running belt 300 and the second horizontal portion 2211 of the second metal member 221 can be better reduced.

[0116] The above-mentioned design is such that the first vertical portion 2112 of the first metal member 211 completely covers or half covers the end surface of the first running board 210 close to the second running board 220, and the second vertical portion 2212 of the second metal member 221 completely covers or half covers the end surface of the second running board 220 close to the first running board 210. The first vertical portion 2112 of the first metal member 211 and the second vertical portion 2212 of the second metal member 221 are in contact with each other, thereby avoiding noise at the connection between the first running board 210 and the second running board 220, thereby improving the user experience.

[0117] It should be noted that the first horizontal portion 2111 of the first metal member 211 completely covers the upper surface of the first running board 210, that is, specifically, along the front-to-back direction of the treadmill, the length of the first horizontal portion 2111 of the first metal member 211 is equal to the length of the first running board 210, and along the width direction of the treadmill, the width of the first horizontal portion 2111 of the first metal member 211 is equal to the width of the first running board 210.

[0118] It should also be noted that when the first vertical portion 2112 of the first metal member 211 completely covers the end surface of the first running board 210 facing the second running board 220, that is, specifically, along the width direction of the treadmill, the length of the first vertical portion 2112 of the first metal member 211 is equal to the width of the first running board 210, and along the height direction of the treadmill, the width of the first vertical portion 2112 of the first metal member 211 is equal to the height of the first running board 210.

[0119] It should also be noted that when the first vertical portion 2112 of the first metal member 211 half covers the end surface of the first running board 210 facing the second running board 220, that is, specifically, along the width direction of the treadmill, the length of the first vertical portion 2112 of the first metal member 211 is equal to the width of the first running board 210, and along the height direction of the treadmill, the width of the first vertical portion 2112 of the first metal member 211 is less than the height of the first running board 210.

[0120] Similarly, it should be noted that the second horizontal portion 2211 of the second metal member 221 completely covers the upper surface of the second running board 220, that is, specifically, along the front-to-back direction of the treadmill, the length of the second horizontal portion 2211 of the second metal member 221 is equal to the length of the second running board 220, and along the width direction of the treadmill, the width of the second horizontal portion 2211 of the second metal member 221 is equal to the width of the second running board 220.

[0121] Similarly, it is also necessary to explain that when the second vertical portion 2212 of the second metal member 221 completely covers the end surface of the second running board 220 facing the first running board 210, that is, specifically, along the width direction of the treadmill, the length of the second vertical portion 2212 of the second metal member 221 is equal to the width of the second running board 220, and along the height direction of the treadmill, the width of the second vertical portion 2212 of the second metal member 221 is equal to the height of the second running board 220.

[0122] Similarly, it is also necessary to explain that when the second vertical portion 2212 of the second metal member 221 half covers the end surface of the second running board 220 facing the first running board 210, that is, specifically, along the width direction of the treadmill, the length of the second vertical portion 2212 of the second metal member 221 is equal to the width of the second running board 220, and along the height direction of the treadmill, the width of the second vertical portion 2212 of the second metal member 221 is less than the height of the second running board 220.

[0123] Optionally, along the height direction of the treadmill, the width of the first vertical portion 2112 is equal to the width of the second vertical portion 2212 , and the width of the first vertical portion 2112 is less than or equal to the height of the first running deck 210 .

[0124] It can be understood that in this embodiment, the width of the first vertical portion 2112 of the first metal member 211 is equal to the width of the second vertical portion 2212, and when the width of the first vertical portion 2112 is less than the height of the first running board 210, the first vertical portion 2112 of the first metal member 211 is semi-covered on the end surface of the first running board 210 facing the second running board 220.

[0125] It is understandable that when the width of the first vertical portion 2112 is equal to the height of the first running board 210 , the first vertical portion 2112 of the first metal member 211 completely covers the end surface of the first running board 210 facing the second running board 220 .

[0126] It should be noted that, in the present application, when the width of the first vertical portion 2112 is less than or equal to the height of the first running board 210 , the width of the first vertical portion 2112 may be set to be at least half of the height of the first running board 210 .

[0127] It should also be noted that the size setting of the second vertical portion 2212 of the second metal member 221 is similar to that of the second running board 220, and this application will not elaborate on this.

[0128] Optionally, the thickness of the first metal member 211 is 0.5-2 mm, and the thickness of the second metal member 221 is 0.5-2 mm.

[0129] It can be understood that the thickness of the first metal part 211 and the thickness of the second metal part 221 are both designed to be 0.5-2 mm. Within this range, not only can the noise generated at the connection between the first running board 210 and the second running board 220 be better avoided, but also the friction between the running belt 300 and the first running board 210, and between the running belt 300 and the second running board 220 can be better reduced.

[0130] It should be noted that the thickness of the first metal member 211 and the thickness of the second metal member 221 in the present application may be 0.5 mm, 1.5 mm, or 2 mm.

[0131] Furthermore, a first outer chamfer is provided at a vertical connection between the first horizontal portion 2111 and the first vertical portion 2112 ; and a second outer chamfer is provided at a vertical connection between the second horizontal portion 2211 and the second vertical portion 2212 .

[0132] It can be understood that a first outer chamfer is provided at the vertical connection between the first horizontal portion 2111 and the first vertical portion 2112, and a second outer chamfer is provided at the vertical connection between the second horizontal portion 2211 and the second vertical portion 2212, which is beneficial for the second running board 220 to rotate relative to the first running board 210, and facilitates the folding and unfolding of the second running board 220 relative to the first running board 210.

[0133] It should be noted that the chamfer radius of the first outer chamfer and the chamfer radius of the second outer chamfer may both be designed to be 1 mm, so as to better achieve folding and unfolding of the second running deck 220 relative to the first running deck 210 .

[0134] Optionally, the first metal member 211 and the first running board 210 are fixed by gluing; the second metal member 221 and the second running board 220 are fixed by gluing.

[0135] It is understandable that the gluing method can well fix the first metal member 211 to the first running board 210 , and fix the second metal member 221 to the second running board 220 .

[0136] Example, reference Figures 5 to 7 As shown in the figure, a plurality of first foot pads 510 may be provided, and the plurality of first foot pads 510 may be arranged at intervals on the sixth support member 116 of the first frame 110; two second foot pads 520 may be provided, one second foot pad 520 is arranged on the inner side of the third bracket 121, and the other second foot pad 520 is arranged on the inner side of the fourth bracket 122.

[0137] Optional, reference Figures 5 to 7 As shown in , a third foot pad 530 may also be provided on the fifth support member 115 , and through the cooperation of the first foot pad 510 , the second foot pad 520 and the third foot pad 530 , when the frame 100 is in the unfolded state, the support stability of the frame 100 is improved.

[0138] In one embodiment, reference Fig.17 and Fig.18 As shown in FIG. , the second foot pad 520 includes:

[0139] A mounting seat 521, wherein the mounting seat 521 is movably connected to the inner wall of the second frame 120 via a second fastener 524;

[0140] A support leg 522, disposed on the mounting seat 521, to support the second frame 120 together with the mounting seat 521;

[0141] The spring pin 523 is passed through the mounting seat 521, and the end of the spring pin 523 close to the inner side of the rear of the frame 100 is set at the first position or the second position of the inner side of the rear of the frame 100; wherein, a positioning groove 1202 is set at the first position, and when the second foot pad 520 is rotated to the supporting state, the end of the spring pin 523 close to the inner side of the rear of the frame 100 is located in the positioning groove 1202 at the first position of the inner side of the rear of the frame 100; when the second foot pad 520 is rotated to the storage state, the end of the spring pin 523 close to the inner side of the rear of the frame 100 is located at the second position of the inner side of the rear of the frame 100.

[0142] The mounting seat 521 is movably mounted on the inner side of the rear portion of the frame 100 through the second fastener 524, and the mounting seat 521 and the supporting leg 522 can rotate together around the second fastener 524 to realize the rotation of the second foot pad 520 from the supporting state to the storage state. When the second foot pad 520 is rotated to the supporting state, the end of the spring pin 523 is located in the positioning groove 1202 at the first position inside the rear portion of the second frame 120, so that the second foot pad 520 can be in the supporting state; when the end of the spring pin 523 is pulled out of the first positioning groove 1202, and when the second foot pad 520 is rotated to the storage state, the end of the spring pin 523 is located at the second position inside the rear portion of the second frame 120, so that the second foot pad 520 can be in the storage state. The present application sets the end of the spring pin shaft 523 in the positioning groove 1202 or the second position at the first position on the inner side of the rear part of the second frame 120, so that when the mounting seat 521 rotates around the second fastener 524, the second foot pad 520 can switch between the supporting state and the storage state, so that the second foot pad 520 can be stored, thereby solving the problem of the treadmill packaging size being too large due to the inability to flexibly adjust the foot pad.

[0143] It should be understood that when the second foot pad 520 rotates to the supporting state, the end of the spring pin 523 can be set at the first position inside the tail of the second frame 120, so that the second foot pad 520 can be in the supporting state. Since the positioning groove 1202 is set at the first position, when the second foot pad 520 rotates to the supporting state, the end of the spring pin 523 is set in the positioning groove 1202, so that the second foot pad 520 can be better in the supporting state, so that the second foot pad 520 supports the second frame 120 of the frame body 100.

[0144] When the second foot pad 520 needs to be rotated to the storage state, it is necessary to pull the end of the spring pin 523 out of the positioning groove 1202, and then rotate the second foot pad 520 to the storage state, so that the second foot pad 520 can be in the storage state, thereby solving the problem of the treadmill packaging size being too large due to the second foot pad 520 not being able to be flexibly adjusted.

[0145] In order to further explain the function of the second foot pad 520, the following is explained in conjunction with the unfolding and folding of the frame 100. When the treadmill needs to be unfolded, that is, the frame 100 needs to be unfolded, and at this time, the second foot pad 520 needs to be rotated to the supporting state. When the second foot pad 520 is rotated to the supporting state, the end of the spring pin 523 is located in the positioning groove 1202 at the first position, so that the second foot pad 520 supports the second frame 120 of the frame 100.
