Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a foldable treadmill. Background Technology

[0002] With the continuous development of technology, fitness equipment is increasingly being used in consumers' work and daily lives. Currently, home fitness equipment typically includes treadmills (or walking machines), exercise machines, and stationary bikes. Among these, treadmills are devices that allow for running or walking exercises indoors. Treadmills operate at a relatively stable pace, resulting in less impact on the user's body, making them suitable for extended use.

[0003] Treadmills typically consist of a running belt, running platform, running board, and motor. The running belt is fitted onto the running platform and running board, and the motor drives the belt to roll, simulating the feeling of walking or running outdoors. This helps users perform aerobic training, improving cardiovascular function, burning fat, and shaping the legs. Foldable treadmills, due to their space adaptability and portability, have become a popular choice for modern home fitness.

[0004] However, the aforementioned foldable treadmills have poor stability, resulting in a poor user experience. Utility Model Content

[0059] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0060] A foldable treadmill is provided, comprising a running platform assembly and a connecting assembly. The running platform assembly includes a first running frame and a second running frame. The connecting assembly is rotatably connected to at least one of the first and second running frames, enabling the running platform assembly to switch between an unfolded state and a folded state. Folding the running platform assembly involves folding the first and second running frames downwards, resulting in a convex shape in the middle area of ​​the foldable treadmill. Therefore, when the user uses the foldable treadmill, the connection point between the two running frames is subjected to downward pressure, preventing deformation caused by folding. This improves the stability and durability of the foldable treadmill and enhances the user experience.

[0061] A foldable treadmill is provided, comprising a running platform assembly and a running board assembly. The running platform assembly includes a first running frame and a second running frame, which are rotatably connected. The running board assembly includes a first running board and a second running board, with the first running board mounted on the first running frame and the second running board mounted on the second running frame. The foldable treadmill can switch between an unfolded and a folded state. When the foldable treadmill is in the unfolded state, the joint between the first and second running boards can be an interlocking toothed seam, resulting in a smaller gap between the first and second running boards. This improves the user experience of using the foldable treadmill. The interlocking toothed seam distributes the stress at the joint to multiple contact points, reducing local stress concentration and lowering the risk of deformation or cracking of the first and second running boards.

[0062] In addition, the interlocking toothed joints can resist the lateral forces with different directions applied to the first and second running boards, thus preventing lateral misalignment caused by mutual sliding between the first and second running boards. Attached Figure Description

Detailed Implementation

[0078] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0079] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0080] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0081] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0082] In related technologies, foldable treadmills have two running frames rotatably connected, and two running boards located on the two frames respectively. When the foldable treadmill is unfolded, the two running boards are joined together to form a single running board, typically with a straight hinge seam between them. Because the straight hinge seam between the two running boards needs to accommodate the tolerances of their edges, the width of the hinge seam is relatively large. When a user steps on the running belt above the hinge seam, they may experience a feeling of stepping into empty space, resulting in a poor user experience.

[0083] If the hinge gap between the two running boards is too small, the downward pressure at the seam during use of the foldable treadmill will cause both boards to be squeezed inwards at the seam. This results in friction or partial mutual compression between the boards at the seam, making uneven stress on the edges more likely and potentially leading to breakage. Therefore, it is necessary to increase the width of the hinge gap between the two running boards. One foldable treadmill uses a flexible layer to cover the gap between the two running boards, but this increases the structural complexity and manufacturing cost of the foldable treadmill.

[0084] In addition, when the aforementioned foldable treadmill is folded for storage, the two running frames fold upwards, which means that the middle area of ​​the foldable treadmill tends to collapse. When the user uses the foldable treadmill, the connection point between the two running frames is subjected to downward pressure, which makes the two running frames more prone to deformation during use, thus making the foldable treadmill more susceptible to malfunction.

[0085] This utility model provides a foldable treadmill that can solve some or all of the technical problems in the above-mentioned related technologies.

[0086] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of a foldable treadmill 10 provided in an embodiment of the present invention. Figure 2 yes Figure 1 The diagram shows the structure of the foldable treadmill 10 in another state. This utility model embodiment provides a foldable treadmill 10, which may include: a running platform assembly 11 and a connecting assembly 14.

[0087] The running platform assembly 11 may include a first running frame 111 and a second running frame 112; a connecting component 14 is connected to one end of the first running frame 111 and one end of the second running frame 112, and the connecting component 14 is rotatably connected to at least one of the first running frame 111 and the second running frame 112, so that the running platform assembly 11 can switch between an unfolded state and a folded state. Figure 1 The treadmill assembly shown is in the deployed state. Figure 2 The treadmill assembly shown is in a folded state.

[0088] The first running frame 111 has a first top surface s11 and a first bottom surface s12, and the second running frame 112 has a second top surface s21 and a second bottom surface s22. When the running platform assembly 11 is in the unfolded state, the first bottom surface s12 and the second bottom surface s22 both face the ground, and the first top surface s11 and the second top surface s21 both face away from the ground. When the running platform assembly 11 is in the folded state, at least a portion of the first bottom surface s12 and the second bottom surface s22 is located between the first top surface s11 and the second top surface s21.

[0089] Thus, since the folding of the running platform assembly in this embodiment of the present invention is a process of folding the first running frame 111 and the second running frame 112 downwards, that is, the middle area of ​​the foldable treadmill 10 tends to bulge, when the user uses the foldable treadmill 10, the connection point of the two running frames is subjected to downward pressure, which can avoid the deformation of the two running frames during folding, thereby improving the stability and durability of the foldable treadmill 10.

[0090] In summary, this utility model embodiment provides a foldable treadmill 10 including a running platform assembly 11 and a connecting assembly 14. The running platform assembly 11 includes a first running frame 111 and a second running frame 112. The connecting assembly 14 is rotatably connected to at least one of the first running frame 111 and the second running frame 112, so that the running platform assembly 11 can switch between an unfolded state and a folded state. When the running platform assembly is folded, it is a process of folding the first running frame 111 and the second running frame 112 downwards. That is, the middle area of ​​the foldable treadmill 10 tends to bulge. Therefore, when the user uses the foldable treadmill 10, the connection point of the two running frames is subjected to downward pressure, which can avoid the deformation of the two running frames during folding, thereby improving the stability and durability of the foldable treadmill 10 and enhancing the user experience.

[0091] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 3 yes Figure 1 The exploded structural diagram of a foldable treadmill 10 shown indicates that the foldable treadmill 10 may include: a running platform assembly 11, a running board assembly 12, a running belt 13, and a drive assembly. The running board assembly 12 is mounted on the running platform assembly 11, the running belt 13 is sleeved on the running platform assembly 11 and the running board assembly 12, and the drive assembly may be mounted on the running platform assembly 11 to drive the running belt 13 to rotate.

[0092] The treadmill assembly 11 may include a first running frame 111 and a second running frame 112, which are rotatably connected to allow the treadmill assembly 11 to switch between an unfolded state and a folded state. It is understood that the state of the treadmill assembly 11 is equivalent to the state of the foldable treadmill 10; that is, when the treadmill assembly 11 is in the unfolded state, the foldable treadmill 10 is also in the unfolded state, and when the treadmill assembly 11 is in the folded state, the foldable treadmill 10 is also in the folded state. Figure 1 The foldable treadmill 10 shown is in its unfolded state, in which users can exercise on the foldable treadmill 10. Figure 2 The foldable treadmill 10 shown is in a folded state. In this state, the foldable treadmill 10 has a small size and occupies less space, and users can store or transport the foldable treadmill 10.

[0093] Please continue to refer to this. Figure 4 , Figure 4 This is an exploded structural diagram of a running board assembly 12 provided in an embodiment of the present invention. The running board assembly 12 may include a first running board 121 and a second running board 122. The first running board 121 may be mounted on a first running frame 111, and the second running board 122 may be mounted on a second running frame 112. The first running board 121 has a plurality of first tooth-shaped protrusions t1 at a portion of its edge, and a first groove c1 is formed between two adjacent first tooth-shaped protrusions t1. The second running board 122 has a plurality of second tooth-shaped protrusions t2 at a portion of its edge, and a second groove c2 is formed between two adjacent second tooth-shaped protrusions t2.

[0094] The shape of the first toothed protrusion t1 matches the shape of the second groove c2, and the shape of the second toothed protrusion t2 matches the shape of the first groove c1. When the running platform assembly 11 is in the unfolded state, the multiple first toothed protrusions t1 are located in the multiple second grooves c2 in a one-to-one correspondence, and the multiple second toothed protrusions t2 are located in the multiple second grooves c2 in a one-to-one correspondence.

[0095] For example, the first running plate 121 may include three first connecting edges and one first splicing edge. The three first connecting edges can be straight edges, and the first splicing edge can be wavy or serrated edges. The first running plate 121 can be connected to the first running frame 111 by bolts at all three first connecting edges. The second running plate 122 may include three second connecting edges and one second splicing edge. The three second connecting edges can be straight edges, and the second splicing edge can be wavy or serrated edges. The second running plate 122 can be connected to the second running frame 112 by bolts at all three second connecting edges. When the running platform assembly 11 is in the unfolded state, the first running plate 121 and the second running plate 122 can be spliced ​​together through the first splicing edge and the second splicing edge, and there is a splicing seam between the first splicing edge and the second splicing edge.

[0096] Since the seam between the first running board 121 and the second running board 122 can be an interlocking toothed seam, the width of the seam can be set according to the tolerance between the corresponding toothed protrusions and grooves. Unlike straight seams, which require accumulating the tolerance of the entire straight edge, this allows for a smaller seam between the first running board 121 and the second running board 122. This results in better flatness of the unfolded running board assembly 12, improving the user experience of the foldable treadmill 10. Furthermore, the absence of a flexible layer on the running board assembly 12 reduces the manufacturing difficulty and cost of the foldable treadmill 10.

[0097] Furthermore, the interlocking toothed joints can distribute the stress at the splice to multiple contact points, reducing local stress concentration and lowering the risk of deformation or cracking of the first running plate 121 and the second running plate 122.

[0098] Furthermore, the interlocking toothed joints can resist lateral forces of different directions applied to the first running plate 121 and the second running plate 122, preventing lateral misalignment caused by mutual sliding between the first running plate 121 and the second running plate 122. Specifically, when the running platform assembly 11 is in the deployed state, the first running frame 111 and the second running frame 112 can be arranged along a first direction, and the first running plate 121 and the second running plate 122 can also be arranged along a first direction. The first direction can be the length direction of the first running frame 111 and the second running frame 112, and the direction of the lateral force is either not parallel to or perpendicular to the first direction.

[0099] In summary, this utility model embodiment provides a foldable treadmill 10 including a running platform assembly 11 and a running board assembly 12. The running platform assembly 11 includes a first running frame 111 and a second running frame 112, which are rotatably connected. The running board assembly 12 includes a first running board 121 and a second running board 122, with the first running board 121 mounted on the first running frame 111 and the second running board 122 mounted on the second running frame 112. The foldable treadmill 10 can switch between an unfolded state and a folded state. When the foldable treadmill 10 is in the unfolded state, the splicing position of the first running board 121 and the second running board 122 can be a toothed joint that interlocks with each other, so that there is a small splicing gap between the first running board 121 and the second running board 122. This can improve the user experience of using the foldable treadmill 10. The interlocking toothed joint can distribute the force at the splicing point to multiple contact points, reduce local stress concentration, and reduce the risk of deformation or cracking of the first running board 121 and the second running board 122.

[0100] Please refer to Figure 3 and Figure 4 In one alternative embodiment, both the first toothed protrusion t1 and the second toothed protrusion t2 are arc-shaped protrusions. Correspondingly, the second groove c2 and the first groove c1 can also be arc-shaped grooves. In this way, the curved structure can disperse the interaction force between the first running plate 121 and the second running plate 122 onto the continuous arc-shaped contact surface, which can alleviate the phenomenon of stress concentration.

[0101] Please refer to Figure 3 and Figure 5 , Figure 5 This is a cross-sectional structural diagram of a foldable treadmill 10 in a folded state according to an embodiment of the present invention. In an optional embodiment, the first running board 121 has a first front side p11 and a first back side p12, and the second running board 122 has a second front side p21 and a second back side p22.

[0102] When the treadmill assembly 11 is in the unfolded state, both the first back side p12 and the second back side p22 face the ground, while both the first front side p11 and the second front side p21 face away from the ground. When the treadmill assembly 11 is in the folded state, the first back side p12 and the second back side p22 are located between the first front side p11 and the second front side p21. When the treadmill assembly 11 is in both the unfolded and folded states, the first back side p12 and the second back side p22 are also located between the first front side p11 and the second front side p21.

[0103] Please refer to Figure 6 , Figure 6This is an exploded structural diagram of another foldable treadmill 10 provided in an embodiment of the present invention. In an optional embodiment, the running platform assembly 11 may further include a first support plate 113 and a second support plate 114. The first support plate 113 is mounted on the first running frame 111 and is connected to the first running plate 121, and is used to support the first running plate 121. The second support plate 114 is mounted on the second running frame 112 and is connected to the second running plate 122, and is used to support the second running plate 122. The first support plate 113 has a plurality of third toothed protrusions t3 at a portion of its edge, and a third groove c3 is formed between two adjacent third toothed protrusions t3. The second support plate 114 has a plurality of fourth toothed protrusions t4 at a portion of its edge, and a fourth groove c4 is formed between two adjacent fourth toothed protrusions t4.

[0104] Specifically, in the direction perpendicular to the surface of the first support plate 113, the third toothed protrusion t3 and the third groove c3 are flush with the first toothed protrusion t1 and the first groove c1, respectively; in the direction perpendicular to the surface of the second support plate 114, the fourth toothed protrusion t4 and the fourth groove c4 are flush with the second toothed protrusion t2 and the second groove c2, respectively.

[0105] The first support plate 113 and the first running frame 111 can be an integral structure, and the second support plate 114 and the second running frame 112 can be an integral structure. The first support plate 113 and the second support plate 114 can improve the overall strength of the running platform assembly 11. The first running plate 121 and the second running plate 122 can be wear-resistant plates with wear-resistant properties and toughness.

[0106] Please refer to Figure 3 , Figure 7 , Figure 8 and Figure 9 , Figure 7 yes Figure 1 The diagram shows another structural view of the foldable treadmill 10. Figure 8 This is a schematic diagram of the structure of a treadmill assembly 11 provided in an embodiment of the present invention. Figure 9 yes Figure 8 The exploded view of the treadmill assembly 11 shown is shown. Figure 7 The diagram also shows a force analysis of the foldable treadmill 10; in an alternative embodiment, when the running platform assembly 11 is in the unfolded state, the first end face m1 of the first running frame 111 facing the second running frame 112 abuts against the second end face m2 of the second running frame 112 facing the first running frame 111.

[0107] Thus, when a user uses the foldable treadmill 10, the greater the force on the running platform assembly 11, the tighter the contact between the first end face m1 of the first running frame 111 and the second end face m2 of the second running frame 112, making the running platform assembly 11 more stable and thereby improving the stability of the foldable treadmill 10.

[0108] In one optional embodiment, the first end face m1 includes a first sub-face m11 and a second sub-face m12 connected together, with the first sub-face m11 located on the side of the second sub-face m12 near the first top face s11. The second end face m2 includes a third sub-face m21 and a fourth sub-face m22 connected together, with the third sub-face m21 located on the side of the fourth sub-face m22 near the second top face s21. When the running platform assembly 11 is in the unfolded state, the first sub-face m11 abuts against the third sub-face m21. The first sub-face m11 can be connected to the first top face s11, and the third sub-face m21 can be connected to the second top face s21.

[0109] In one exemplary embodiment, the first sub-face m11 is not parallel to the first top face s11, that is, there is an angle between the first sub-face m11 and the first top face s11. For example, the first sub-face m11 is perpendicular to the first top face s11. The third sub-face m21 is not parallel to the second top face s21, that is, there is an angle between the third sub-face m21 and the second top face s21. For example, the third sub-face m21 is perpendicular to the second top face s21.

[0110] The first sub-surface m11 and the second sub-surface m12 are not parallel and have an obtuse angle between them. The third sub-surface m21 and the fourth sub-surface m22 are not parallel and have an obtuse angle between them. When the running platform assembly 11 is in the unfolded state, the second sub-surface m12 is parallel to the fourth sub-surface m22, and the second sub-surface m12 can also abut against the fourth sub-surface m22.

[0111] Please refer to Figure 7 When a user applies a force towards the ground to the foldable treadmill 10, the joint between the first running frame 111 and the second running frame 112 is located in the middle area of ​​the foldable treadmill 10. This causes a downward tendency for the end of the first running frame 111 near the second running frame 112 and the end of the second running frame 112 near the first running frame 111. At this time, the mutually abutting first sub-surface m11 and third sub-surface m21 can bear the load caused by the downward tendency and provide a target-direction support force F2 to the first running frame 111 and the second running frame 112, thereby preventing the middle area of ​​the foldable treadmill 10 from collapsing downward. The target direction is perpendicular to either the first sub-surface m11 or the third sub-surface m21.

[0112] Please refer to Figure 7 , Figure 8 and Figure 9 In one optional embodiment, the connecting assembly 14 may include a connecting shaft 141. The first running frame 111 has two lug portions 1111 at one end facing the connecting shaft 141, and the second running frame 112 has a protruding lug 1121 at one end facing the connecting shaft 141. Each lug portion 1111 has a first connecting hole, and the protruding lug 1121 has a second connecting hole. The protruding lug 1121 is located between the two lug portions 1111, and the second connecting hole is aligned with the two first connecting holes. The connecting shaft 141 passes through the two first connecting holes and the second connecting hole. By placing the protruding lug 1121 of the second running frame 112 between the two lug portions 1111 of the first running frame 111, the relative displacement of the first running frame 111 and the second running frame 112 in a first direction can be limited, preventing lateral misalignment of the first running frame 111 and the second running frame 112. The second sub-face m12 can be located on the two ear-shaped parts 1111. When the running platform assembly 11 is in the unfolded state, the fourth sub-face m22 can be located on the side of the second sub-face m12 away from the ground. Both the ear-shaped parts 1111 and the convex ears 1121 are in a downward convex state.

[0113] It is understood that the foldable treadmill 10 in this embodiment of the present invention has four ear bases 1111 and two protruding ears 1121. The four ear bases 1111 are located in pairs on the left and right sides of the first running frame 111, and the two protruding ears 1121 are located on the left and right sides of the second running frame 112.

[0114] Please refer to Figure 10 , Figure 10 This is a schematic diagram of another foldable treadmill 10 provided by an embodiment of the present invention. In an optional embodiment, the foldable treadmill 10 may further include a first magnetic chuck 15 and a second magnetic chuck 16. The first magnetic chuck 15 is mounted on the first bottom surface s12 of the first running frame 111, and the second magnetic chuck 16 is mounted on the second bottom surface s22 of the second running frame 112. When the running platform assembly 11 is in a folded state, the first magnetic chuck 15 and the second magnetic chuck 16 are attracted to each other. Both the first magnetic chuck and the second magnetic chuck can be magnets, or one of the first magnetic chuck 15 and the second magnetic chuck 16 can be a magnet and the other can be an iron sheet. The first magnetic chuck 15 can be glued or embedded in the first running frame 111, and the second magnetic chuck 16 can be glued or snapped onto the second running frame 112. Thus, by attracting the first magnetic chuck 15 and the second magnetic chuck 16, the stability of the running platform assembly 11 in the folded state can be improved.

[0115] Please refer to Figure 10In one optional embodiment, the foldable treadmill 10 may further include an anti-detachment stop 17, which is installed on the side of the running platform assembly 11 opposite to the running board assembly 12 and located on the side of the running belt 13 opposite to the running platform assembly 11. That is, a portion of the structure of the running belt 13 is located between the anti-detachment stop 17 and the running platform assembly 11 to limit the running belt 13 during the folding of the foldable treadmill 10, preventing the running belt 13 from detaching from the running platform assembly 11 and avoiding the running belt 13 from bending arbitrarily, thus affecting the folding process.

[0116] The anti-detachment component 17 may include a strip-shaped limiting member and two mounting seats. The two mounting seats can be fixedly connected to the bottom surface of the first running frame 111, and both ends of the anti-detachment component 17 can be fixedly connected to the two mounting seats, so that when the foldable treadmill 10 is operating normally, there is a gap between the anti-detachment component 17 and the running belt 13, thereby preventing the anti-detachment component 17 from affecting the movement of the running belt 13. For example, the strip-shaped limiting member can be a flexible bandage.

[0117] Please refer to Figure 10 In one optional embodiment, the first running frame 111 has a support foot pad 1112 on the side opposite to the first running board 121, and the second running frame 112 has a storage groove 1122 on the side opposite to the second running board 122. In a direction parallel to the traveling direction of the running belt 13, that is, in a first direction, the length of the first running frame 111 is less than the length of the second running frame 112. When the running platform assembly 11 is in the folded state, the support foot pad 1112 is located in the storage groove 1122. In this way, the foldable treadmill 10 can be made to have a more compact structure after folding.

[0118] The foldable treadmill 10 may also include a remote control 19, and the bottom surface of the second running frame 112 may have a remote control storage slot in which the remote control 19 can be stored.

[0119] Please refer to Figure 10 In one exemplary embodiment, the foldable treadmill 10 may further include a lifting assembly 18, and both the lifting assembly 18 and the drive assembly can be mounted on the end of the second running frame 112 opposite to the first running frame 111. When the incline of the foldable treadmill 10 is changed using the lifting assembly 18, compared to the related art which is supported only by a hinged structure, the first running frame 111 and the second running frame 112 in this embodiment of the present invention can abut against each other through the first end face m1 and the second end face m2, which can improve the stability of the foldable treadmill 10 in the inclined state.

[0120] In an alternative embodiment, the lifting assembly 18 may also be installed at the end of the first running frame 111 opposite to the second running frame 112.

[0121] Please refer to Figure 11 , Figure 11 This is a schematic diagram of another foldable treadmill 10 provided by the present invention. The second bottom surface s22 of the second running frame 112 is stepped. The second bottom surface s22 includes a folding sub-surface s221 and a supporting sub-surface s222 arranged in a direction away from the connecting component 14 (that is, the connecting pivot 141).

[0122] When the treadmill assembly 11 is in the folded state, the first bottom surface s12 of the first running frame 111 and the folded sub-surface s221 of the second running frame 112 are located between the first top surface s11 of the first running frame 111 and the second top surface s21 of the second running frame 112, and the supporting sub-surface s222 of the second running frame 112 is flush with the first top surface s11 of the first running frame 111. In this way, the surface flatness of the foldable treadmill 10 after folding can be improved.

[0123] The foldable treadmill 10 in this embodiment may further include a motor (not shown) and a transmission component (not shown). The motor is connected to a roller (not shown) via a drive shaft and the transmission component (not shown), thereby enabling the motor's drive shaft to drive the roller of the treadmill, thus controlling the rotation of the roller, which in turn drives the running belt to rotate. Optionally, the foldable treadmill 10 may further include an encoder and a controller connected to the motor, thereby controlling the motor's operation. Optionally, the transmission component (not shown) may include at least one or a combination of a reducer (not shown), a pulley (not shown), a belt (not shown), a sprocket (not shown), and a chain (not shown).

[0124] In one alternative embodiment, the motor, transmission component, and a roller controlled by the motor via the transmission component are all disposed within the second running frame 112, and positioned between the support sub-surface s222 and the second top surface s21 of the second running frame 112. When the support sub-surface s222 of the second running frame 112 is flush with the first top surface s11 of the first running frame 111, the foldable treadmill 10 can be stably placed on a horizontal surface (e.g., the ground).

[0125] It is understood that the first top surface s11 and the first bottom surface s12 of the first running frame 111 and the second top surface s21 and the second bottom surface s22 of the second running frame 112 in the present utility model embodiment can refer to the actual upper and lower surfaces of the first running frame 111 and the second running frame 112, or they can refer to the upper and lower interfaces of the first running frame 111 and the second running frame 112.

[0126] Please refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram illustrating the folding process of a foldable treadmill 10 provided in this embodiment of the present invention. Figure 13A schematic diagram illustrating the folding process of another foldable treadmill 10 provided in this embodiment of the present invention. Figure 13 The running belt is not shown in the diagram, but the engagement and disengagement process of the first running board 121 and the second running board 122 is clearly illustrated. When the user uses the foldable treadmill 10, it can be in the unfolded state. When the user needs to store the foldable treadmill 10, the first running frame 111 can be folded downwards and folded to the side with the second running frame 112, thereby reducing the size and space occupied by the foldable treadmill 10. For foldable treadmills 10 that need to be transported, the product packaging size of the foldable treadmill 10 after storage is smaller, which can reduce the production and transportation costs for enterprises.
