TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of fitness equipment, in particular to a treadmill. BACKGROUND

[0002] As a kind of fitness equipment, the treadmill generally includes a treadmill frame, a running board, a running belt and a driving assembly. However, the running platform composed of the treadmill frame and the running board and the running belt occupies a large space, which is not only high in transportation cost but also inconvenient to store.

[0003] In the prior art, the problem of large space occupation of the treadmill is solved by designing the treadmill into a foldable structure. However, for the treadmill with a foot pad structure, the body of the treadmill is generally designed into a foldable structure or the handrail of the treadmill is designed into a foldable structure. Although the space occupied after folding can be reduced to some extent, the overall structure of the treadmill is irregular and the foot pad is protruding, which leads to an excessively large packaging size of the treadmill and is inconvenient for packaging.

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

[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art. CONTENT OF THE UTILITY MODEL

[0006] The purpose of the embodiments of the present disclosure is to provide a treadmill, which is simple to fold and has a regular overall structure and a small size after folding, and is convenient for packaging.

[0007] According to the embodiments of the present disclosure, a treadmill is provided, which includes:

[0008] The frame body includes a first frame, a second frame and a shaft pin assembly, the first frame and the second frame are rotationally connected through the shaft pin assembly, so that the frame body can be switched between an unfolded state and a folded state;

[0009] The running board module includes a first running board and a second running board, the first running board is arranged on the first frame, and the second running board is arranged on the second frame;

[0010] The running belt and the driving module, the running belt is sleeved on the running board module, and the driving module is installed on the frame body and used to drive the running belt;

[0011] The foot pad module includes a first foot pad and a second foot pad, the first foot pad is arranged on the first frame, and the second foot pad is rotationally arranged on the second frame and can be switched between a supporting state and a storage state.

[0012] When the frame body is in the unfolded state, the first running plate and the second running plate 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 body is in the folded state, the second running plate can be accommodated on the first running plate, and the second foot pad can be in an accommodation state to be accommodated inside the second frame.

[0013] The technical solutions provided by the present disclosure can include 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 shaft pin assembly, so that the frame body can be switched between the unfolded state and the folded state, so that the treadmill can be unfolded and folded. After unfolding the frame body of the treadmill, the frame body, the running plate module, the running belt and the driving module cooperate to provide a running platform for the user. After folding the frame body of the treadmill, the space occupied by the treadmill can be reduced, which is convenient for the user to store and transport. On the other hand, the first foot pad is arranged on the first frame, and the second foot pad is rotatably arranged on the second frame, so that when the frame body is in the unfolded state, the frame body can be stably supported on the ground by the first foot pad and the second foot pad.

The second foot pad 520 can be switched between the supporting state and the storage state, so that when the frame body 100 is in the folded state, the second foot pad 520 can be in the storage state and stored in the inner side of the second frame 120, so that the treadmill occupies less space in the folded state, and the overall structure of the treadmill is regular, thereby solving the problem that the treadmill is not convenient to package due to the flexible adjustment of the foot pad.

[0047] In the following, the above-mentioned treadmill in the present example embodiment will be described in more detail. Figures 1 to 18 The above-mentioned treadmill in the present example embodiment will be described in more detail.

[0048] In one embodiment, referring to FIG. 1, the first frame 110 is arranged on the second frame 120, and the first frame 110 and the second frame 120 are rotatably connected through the shaft pin assembly 130. Figures 1 to 7 The inner side wall of the first frame 110 is provided with a first support and a second support 114, which are used to carry the first running board 210.

[0049] The inner side wall of the second frame 120 is provided with a third support 123 and a fourth support 124, which are used to carry the second running board 220; wherein when the frame body 100 is in the unfolded state, the fourth support 124 partially extends to the first frame 110, so that the fourth support 124 supports the first running board 210 and the second running board 220 at the same time.

[0050] In the above arrangement, on the one hand, the first support and the second support 114 arranged on the inner side wall of the first frame 110 can better support the first running plate 210, and the third support 123 and the fourth support 124 arranged on the inner side wall of the second frame 120 can better support the second running plate 220, so that the first support, the second support 114, the third support 123 and the fourth support 124 can guarantee the flatness of the front running plate and the rear running plate; on the other hand, the fourth support 124 extends along the front-rear direction of the treadmill, and when the frame body 100 is in the unfolded state, the fourth support 124 can extend to the first frame 110, so that the fourth support 124 can support the first running plate 210 while supporting the second running plate 220, realize the common support of the joint of the first running plate 210 and the second running plate 220, avoid the height difference, and improve the user's foot feeling.

[0051] It should be noted that the heights of the first running plate 210 and the second running plate 220 are equal, and the installation heights of the third support 123 and the fourth support 124 on the inner side wall of the second frame 120 are equal to the installation heights of the first support and the second support 114 on the inner side wall of the first frame 110, so that the upper surfaces of the first running plate 210 and the second running plate 220 are flush.

[0052] It should be further noted that the first running plate 210 is fixedly connected with the first support and the second support 114 through the fixing member. The second running plate 220 is fixedly connected with the third support 123 and the fourth support 124 through the fixing member.

[0053] Further, the bottom of the first frame 110 is provided with a fifth support 115; when the frame body 100 is in the unfolded state, the fifth support 115 extends to the second frame 120, so that the fifth support 115 supports the first frame 110 and the second frame 120 at the same time.

[0054] In the above arrangement, the fifth support 115 is arranged at the bottom of the first frame 110, and when the frame body 100 is in the unfolded state, the fifth support 115 extends to the second frame 120, so that the extension section of the fifth support 115 is located at the bottom of the second frame 120, thereby realizing that the fifth support 115 supports the joint of the first frame 110 and the second frame 120 at the same time, so that the first frame 110 and the second frame 120 can be in the same horizontal plane.

[0055] Optionally, the front bottom of the first frame 110 is provided with a sixth support 116, and the first foot pad 510 is arranged on the sixth support 116. By further arranging the sixth support 116 on the front bottom of the first frame 110, and arranging the first foot pad 510 on the sixth support 116, the first frame 110 is more stably supported by the cooperation of the sixth support 116 and the first foot pad 510.

[0056] Optionally, the first support includes two ear plates 113, and the two ear plates 113 are arranged on the corresponding inner side walls of the first frame 110 respectively.

[0057] It should be understood that the second support 114, the third support 123 and the fourth support 124 in the embodiment can be rectangular support frames, and in order to realize the support of the first frame 110 while reducing the weight, the first support is designed as an ear plate 113 in the application. The ear plate 113 can support the first frame 110 while reducing the weight of the entire running board support assembly compared with the rectangular support frame. The ear plate 113 is fixedly connected to the corresponding inner side wall of the first frame 110 through a fixing member.

[0058] Specifically, the fourth support 124 is connected to the second running board 220 through a fixing member. It should be understood that the fourth support 124 is only in contact with the bottom of the first running board 210, and when the second frame 120 rotates relative to the first frame 110, the second running board 220 can rotate with the second frame 120 relative to the first running board 210 and the first frame 110.

[0059] In one embodiment, referring to Figures 4 to 10 The shaft pin assembly 130 includes:

[0060] A shaft pin body 131 is located on one side of the frame body 100 along the height direction of the frame body 100, wherein the axial direction of the shaft pin body 131 is parallel to the width direction of the treadmill, and the height direction of the frame body 100 is parallel to the height direction of the treadmill;

[0061] A first shaft pin connecting member 132 is arranged on the first frame 110 and fixedly connected to the shaft pin body 131;

[0062] A second shaft pin connecting member 133 is arranged on the second frame 120 and rotatably connected to the shaft pin body 131, so that the frame body 100 can be switched between the unfolded state and the folded state.

[0063] The first shaft pin connector 132 is arranged on the first frame 110 and fixedly connected with the shaft pin body 131, and the second shaft pin connector 133 is arranged on the second frame 120 and rotatably connected with the shaft pin body 131, so as to rotatably connect the first frame 110 and the second frame 120 around the shaft pin body 131, and further enable the frame body 100 to switch between the unfolded state and the folded state; when the frame body 100 is in the unfolded state, the first frame 110 and the second frame 120 are arranged in sequence along the front-rear direction of the treadmill, and the first running plate 210 and the second running plate 220 are located in the same plane to form a running track for the user to tread on; when the frame body 100 is in the folded state, the first frame 110 and the second frame 120 are arranged along the height direction of the treadmill, and the second running plate 220 can be accommodated on the first running plate 210, so as to facilitate the transportation and storage of the treadmill.

[0064] It should be explained that the above-mentioned shaft pin assembly 130 is used to fold and accommodate the running plate of the treadmill, and the shaft pin assembly 130 has simple structure, small size, and only needs to rotate the second frame 120 relative to the first frame 110 to realize the folding and unfolding of the treadmill, which is simple and convenient to operate.

[0065] For example, the first frame 110 comprises:

[0066] The first support 111 and the second support 112 are arranged in parallel relative to each other.

[0067] The second frame 120 comprises:

[0068] The third support 121 and the fourth support 122 are arranged in parallel relative to each other; the third support 121 is on the same side as the first support 111, and the second support 112 is on the same side as the fourth support 122.

[0069] Specifically, two shaft pin assemblies 130 are arranged, and the first support 111 and the third support 121 are rotatably connected through one shaft pin assembly 130 between the end portions close to each other; and the second support 112 and the fourth support 122 are rotatably connected through another shaft pin assembly 130 between the end portions close to each other.

[0070] The first support 111, the second support 112, the third support 121 and the fourth support 122 extend along the front-rear direction of the treadmill; the second support 114 is arranged perpendicularly to the first support 111, and two ends of the second support 114 are connected to the first support 111 and the second support 112 respectively; the third support 123 and the fourth support 124 are arranged perpendicularly to the third support 121 respectively, and two ends of the third support 123 are connected to the third support 121 and the fourth support 122 respectively, and two ends of the fourth support 124 are connected to the third support 121 and the fourth support 122 respectively; the two ear plates 113 of the first support are arranged on the first support 111 and the second support 112 one by one respectively; the fifth support 115 is arranged perpendicularly to the first support 111, and two ends of the fifth support 115 are connected to the bottom of the first support 111 and the bottom of the second support 112 respectively; the sixth support 116 is arranged perpendicularly to the first support 111, and two ends of the sixth support 116 are connected to the bottom of the first support 111 and the bottom of the second support 112 respectively.

[0071] Further, the first shaft pin connecting piece 132 comprises a first connecting plate 1321 and a first shaft pin sleeve, the first connecting plate 1321 is arranged on the first frame 110, and the first shaft pin sleeve is connected to the first connecting plate 1321 and fixedly sleeved on the shaft pin body 131.

[0072] The second shaft pin connecting piece 133 comprises a second connecting plate 1331 and a second shaft pin sleeve 1332, the second connecting plate 1331 is arranged on the second frame 120, and the second shaft pin sleeve 1332 is connected to the second connecting plate 1331 and rotatably sleeved on the shaft pin body 131.

[0073] When the frame body 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 abut against each other; when the frame body 100 is in the folded state, the first connecting plate 1321 and the second connecting plate 1331 are spaced apart and arranged oppositely along the height direction of the treadmill.

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

[0075] Further, the first shaft pin sleeve comprises a first sleeve ring 1322 and a second sleeve ring 1323, and the first sleeve ring 1322 and the second sleeve ring 1323 are arranged in an axial direction of the shaft pin body 131; wherein, in the axial direction of the shaft pin body 131, the second shaft pin sleeve 1332 is located between the first sleeve ring 1322 and the second sleeve ring 1323.

[0076] In the above structure, on the one hand, the first shaft pin sleeve is further arranged in the form of the first sleeve ring 1322 and the second sleeve ring 1323 to improve the connection stability of the first shaft pin connecting piece 132 and the shaft pin body 131, and on the other hand, the second shaft pin sleeve 1332 is arranged between the first sleeve ring 1322 and the second sleeve ring 1323 to improve the rotational connection stability of the second shaft pin connecting piece 133 and the shaft pin body 131.

[0077] Further, a first fastener 134 is threadedly connected to one end of the shaft pin body 131 towards the outside of the frame body 100, and when the first fastener 134 is fastened to the shaft pin body 131, the first fastener 134 abuts against the second sleeve ring 1323. By arranging the first fastener 134 on the shaft pin body 131, the first shaft pin sleeve is fixed relative to the shaft pin body 131 through the first fastener 134, and when the second frame 120 is flipped for folding the treadmill operation, only the second shaft pin sleeve 1332 needs to be rotated relative to the shaft pin body 131 around the axial direction of the shaft pin body 131.

[0078] Further, the shaft pin body 131 comprises a second shaft body 1311 and a third shaft body 1312 extending along the axial direction of the shaft pin body 131, the third shaft body 1312 is connected to one end of the second shaft body 1311 away from the frame body 100, and the diameter of the third shaft body 1312 is smaller than that of the second shaft body 1311; wherein the first shaft pin sleeve and the second shaft pin sleeve 1332 are sleeved on the third shaft body 1312, and along the axial direction of the shaft pin body 131, the first sleeve ring 1322 is located between the second shaft body 1311 and the second shaft pin sleeve 1332.

[0079] The above structure design of the shaft pin body 131 not only ensures the stable connection of the shaft pin body 131 with the first shaft pin sleeve and the second shaft pin sleeve 1332, but also can minimize the volume of the shaft pin body 131.

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

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

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

[0083] Optionally, the outer diameter of the first sleeve ring 1322, the outer diameter of the second sleeve ring 1323 and the outer diameter of 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 sleeve ring 1322, the second sleeve ring 1323 and the second shaft pin sleeve 1332, the outer periphery of the second shaft body 1311 is flush with the outer periphery of the first sleeve ring 1322, the second sleeve ring 1323 and the second shaft pin sleeve 1332, and there is no protrusion on the entire shaft pin body 131, so as to improve the safety and aesthetics.

[0084] In one embodiment, referring to Figure 3 and Figure 4 , and Figures 11 to 13As shown in the figure, the shaft pin body 131 protrudes from the upper surface of the frame body 100, the first frame 110 is provided with a first edge strip 117, the first edge strip 117 is provided with a first pair of insertion structures, the second frame 120 is provided with a second edge strip 125, and the second edge strip 125 is provided with a second pair of insertion structures;

[0085] When the frame body 100 is in the unfolded state, along the front-rear direction of the treadmill, the first edge strip 117 and the second edge strip 125 are located on both sides of the shaft pin body 131, and the shaft pin body 131 is accommodated in the gap between the first edge strip 117 and the second edge strip 125; when the frame body 100 is in the folded state, along the height direction of the treadmill, the first edge strip 117 and the second edge strip 125 are located between the first frame 110 and the second frame 120, and the first pair of insertion structures and the second pair of insertion structures are connected by insertion.

[0086] For the shaft pin body 131 protruding from the upper surface of the frame body 100, in the embodiment, the first edge strip 117 and the second edge strip 125 are arranged on the first frame 110 and the second frame 120 respectively, so that when the frame body 100 is in the unfolded state, the first edge strip 117 and the second edge strip 117 arranged on both sides of the shaft pin body 131 can hide the shaft pin body 131, avoiding the shaft pin body 131 protruding from the frame body 100, thereby improving the safety of the user using the treadmill; and by arranging the first pair of insertion structures and the second pair of insertion structures on the first edge strip 117 and the second edge strip 125 respectively, the first pair of insertion structures and the second pair of insertion structures can be connected by insertion, so that when the frame body 100 is in the folded state, the first frame 110 and the second frame 120 are closed tightly to make the treadmill closed tightly after folding.

[0087] For example, the first edge strip 117 is arranged on the first support 111 and the second support 112 of the first frame 110, and the second edge strip 125 is arranged on the third support 121 and the fourth support 122 of the second frame 120, wherein the first edge strip 117 and the second edge strip 125 extend along the length direction of the treadmill, so as to ensure that when the frame body 100 is in the unfolded state, the degree of protrusion of the shaft pin body 131 arranged on the upper surface of both sides of the frame body 100 from the frame body 100 is reduced, and when the frame body 100 is in the folded state, the first frame 110 and the second frame 120 are closed tightly.

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

[0089] Further, the first pair of insertion structures comprises a plurality of first toothed strips 1171 arranged on the first side strip 117, and the second pair of insertion structures comprises a plurality of second toothed strips 1251 arranged on the second side strip 125; when the frame body 100 is in the folded state, each second toothed strip 1251 on the second side strip 125 is accommodated between two first toothed strips 1171 arranged adjacently on the first side strip 117.

[0091] Optionally, the size of the first toothed strip 1171 in the width direction of the frame body 100 gradually decreases in the direction away from the first side strip 117; and the size of the second toothed strip 1251 in the width direction of the frame body 100 gradually decreases in the direction away from the second side strip 125.

[0092] Through the above-mentioned size limitation of the first toothed strip 1171 and the second toothed strip 1251, the projection of the first toothed strip 1171 in the treadmill front-rear direction in the direction away from the first side strip 117 is tapered, and the projection of the second toothed strip 1251 in the treadmill front-rear direction in the direction away from the second side strip 125 is tapered. This shape arrangement makes the resistance of the first pair of insertion structures and the second pair of insertion structures appropriate during the insertion process, and the first toothed strip 1171 and the second toothed strip 1251 are fitted in the form of an inclined surface, so that the first pair of insertion structures and the second pair of insertion structures are tightly inserted.

[0093] Optionally, the surface of the first toothed strip 1171 away from the first side strip 117 is an arc surface, and the surface of the second toothed strip 1251 away from the second side strip 125 is an arc surface. The arc surface arrangement on the first toothed strip 1171 and the arc surface arrangement on the second toothed strip 1251 can avoid mutual damage of the first pair of insertion structures and the second pair of insertion structures during the insertion process, and also make the resistance of the first pair of insertion structures and the second pair of insertion structures appropriate during the insertion process.

[0127] It should be further noted that the size of the second vertical part 2212 of the second metal piece 221 is set in the same way as the second running plate 220, and the present application will not be repeated here.

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

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

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

[0134] Optionally, the first metal piece 211 is fixed to the first running plate 210 by adhesive; and the second metal piece 221 is fixed to the second running plate 220 by adhesive.

[0135] It can be understood that the adhesive can well fix the first metal piece 211 to the first running plate 210 and fix the second metal piece 221 to the second running plate 220.

[0136] For example, as shown in Figures 5 to 7 , the first foot pad 510 can be provided with a plurality of first foot pads 510, which are arranged on the sixth support 116 of the first frame 110; and the second foot pad 520 can be provided with two second foot pads 520, one of which is arranged on the inner side of the third support 121, and the other of which is arranged on the inner side of the fourth support 122.

[0137] Optionally, as shown in Figures 5 to 7 , the fifth support 115 can further be provided with a third foot pad 530, and through cooperation of the first foot pad 510, the second foot pad 520 and the third foot pad 530, the support stability of the frame body 100 is improved when the frame body 100 is in the unfolded state.

[0138] In one embodiment, as shown in Figure 17 and Figure 18 , the second foot pad 520 comprises:

[0139] a mounting seat 521 movably connected to the inner side wall of the second frame 120 by a second fastener 524;

[0140] a supporting leg 522 arranged on the mounting seat 521 to support the second frame 120 together with the mounting seat 521;

[0141] a spring pin shaft 523 penetrating the mounting seat 521, and an end of the spring pin shaft 523 close to the inner side of the tail of the frame body 100 is arranged at a first position or a second position of the inner side of the tail of the frame body 100; wherein the first position is provided with a positioning groove 1202, when the second foot pad 520 is rotated to the supporting state, the end of the spring pin shaft 523 close to the inner side of the tail of the frame body 100 is located at the positioning groove 1202 at the first position of the inner side of the tail of the frame body 100; when the second foot pad 520 is rotated to the storage state, the end of the spring pin shaft 523 close to the inner side of the tail of the frame body 100 is located at the second position of the inner side of the tail of the frame body 100.

[0142] The mounting seat 521 is movably mounted in the tail inner side of the frame body 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 shaft 523 is located at the first position of the positioning groove 1202 in the tail inner side of the second frame 120 to realize that the second foot pad 520 can be in the supporting state; when the end of the spring pin shaft 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 shaft 523 is located at the second position in the tail inner side of the second frame 120 to realize that the second foot pad 520 can be in the storage state. Through the end of the spring pin shaft 523 being arranged in the first position of the positioning groove 1202 or the second position in the tail inner side of the second frame 120, the second foot pad 520 can be switched between the supporting state and the storage state during the rotation of the mounting seat 521 around the second fastener 524, so that the second foot pad 520 can be stored, thereby solving the problem of the too large packaging size of the treadmill caused by the inability of the foot pad to be flexibly adjusted.

[0143] It needs to be understood that when the second foot pad 520 is rotated to the supporting state, the end of the spring pin shaft 523 can be arranged at the first position in the tail inner side of the second frame 120 to enable the second foot pad 520 to be in the supporting state. Since the positioning groove 1202 is arranged at the first position, when the second foot pad 520 is rotated to the supporting state, the end of the spring pin shaft 523 is arranged in the positioning groove 1202 to enable the second foot pad 520 to be better in the supporting state, thereby realizing that the second foot pad 520 supports the second frame 120 of the frame body 100.

[0144] When it is needed to rotate the second foot pad 520 to the storage state, the end of the spring pin shaft 523 needs to be pulled out of the positioning groove 1202, and then the second foot pad 520 is rotated to the storage state, so that the second foot pad 520 can be in the storage state, thereby realizing that the second foot pad 520 is stored, thereby solving the problem of the too large packaging size of the treadmill caused by the inability of the second foot pad 520 to be flexibly adjusted.

[0145] To further illustrate the role of the second foot pad 520, the following describes the unfolding and folding of the frame body 100. When the treadmill needs to be unfolded, i.e., the frame body 100 needs to be unfolded, the second foot pad 520 needs to be turned to the supporting state. When the second foot pad 520 is turned to the supporting state, the end of the spring pin shaft 523 is located in the positioning groove 1202 at the first position to support the second frame 120 of the frame body 100. When the treadmill needs to be folded, i.e., the frame body 100 needs to be folded, the second foot pad 520 needs to be turned to the storage state. Specifically, the spring pin shaft 523 is pulled out of the positioning groove 1202 at the first position, and then the second foot pad 520 is turned to the storage state. When the second foot pad 520 is turned to the storage state, the end of the spring pin shaft 523 is located at the second position inside the tail of the second frame 120 to store the second foot pad 520. It should be noted that the inside of the tail of the second frame 120 mentioned above can be understood as: along the front-to-back direction of the treadmill, the inside of the side of the second frame 120 away from the first frame 110.
