DETAILED DESCRIPTION

[0032] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0033] Figure 1 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 1 . Figure 2 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 2 .

[0034] See also Figure 1 and Figure 2 According to an embodiment of the present application, a fitness device is provided, which includes: a main body 1, on which a treadmill 2 is provided; a first column 31, which is rotatably connected to the main body 1 and is located on the side of the treadmill 2; a second column 32, which is slidably arranged on the first column 31 along the longitudinal direction of the first column 31; an adjusting rod 33, one end of the adjusting rod 33 is rotatably connected to the main body 1 and is located on the same side of the treadmill 2 as the first column 31, and the other end of the adjusting rod 33 is rotatably connected to the second column 32; and a locking member 4, which is used to lock the first column 31 and the second column 32.

[0035] The fitness device provided in the embodiment of the present application controls the second column 32 to slide relative to the first column 31, controls the adjustment rod 33 and the first column 31 to rotate relative to the main body 1, thereby causing the first column 31 and the second column 32 to rotate relative to the main body 1. By rotating the first column 31 and the second column 32 to different positions above the main body 1, the first column 31 and the second column 32 can meet different support requirements and storage requirements, thereby broadening the scope of use of the fitness device and facilitating storage.

[0036] Specifically, the main body 1 is the base of the fitness device, such as a treadmill for mounting a treadmill belt 2. The main body 1 is placed on a support surface to support the entire fitness device. For example, when the fitness device is in use, the base can be placed on a support surface, such as the ground. When the fitness device needs to be stored, the base can be leaned against a wall or placed in a corner of the ground.

[0037] The main body 1 is provided with a roller shaft for the treadbelt 2 to be mounted on. The roller shaft is connected to a driving member fixed on the main body 1. The driving member can be a driving motor. The driving member drives the roller shaft to rotate, and the roller shaft drives the treadbelt 2 to run. The user can run and exercise on the treadbelt 2.

[0038] The first column 31 and the second column 32 can be used to fix the operating table 51 and fitness-related components such as the armrests 52 and the pad 61, so that the user can use the operating table 51 to control the fitness device during fitness, and use the armrests 52, the pad 61 and other fitness-related components to support different parts of the body, thereby achieving the purpose of assisting fitness.

[0039] Depending on the specific rotation angles of the first and second columns 31, 32 on the main body 1, the first and second columns 31, 32 and the fitness-related components mounted thereon can support the user's head, torso, limbs, and other parts. For example, when the columns are upright relative to the main body 1, the first and second columns 31, 32 can be used to display the operating table 51 to the user, and the armrests 52 can be held by the user. When the first and second columns 31, 32 are attached to the main body 1, the first and second columns 31, 32 can also be used to slide the cushion 61 for various exercises such as Pilates and rowing. When the first and second columns 31, 32 are attached to the main body 1, the overall footprint of the fitness device can be reduced, and the first and second columns 31, 32 can be attached to a wall for easy storage.

[0040] Figure 3 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 3 .

[0041] See also Figure 3 Two first columns 31 are provided, symmetrically arranged on either side of the main body 1 and located in front of the treadmill 2 in its normal operating direction. The first columns 31 are pivotally connected to the side of the main body 1 via a first rotating member 34, which can be a hinge. This allows the user to position the first and second columns 31, 32 in front of the main body 1 while using the treadmill 2, conveniently using the operating platform 51, the second column 32, and / or the handrails 52 for support and exercise assistance. A sliding groove 323 is defined axially in the first column 31, and the second column 32 is inserted into the sliding groove 323 to achieve a sliding connection with the first column 31.

[0042] One end of the adjustment rod 33 is rotatably connected to the main body 1 via a second rotating member 35, which can be a hinge. The other end of the adjustment rod 33 is rotatably connected to the middle portion of the second column 32 via a third rotating member 36, which can be a rotating shaft integrally formed with the adjustment rod 33. The first, second, and third rotating members 34, 35, and 36 rotate in the same direction, with the normal operating direction of the treadbelt 2 as a reference. The adjustment rod 33 is located on the same side and rearward of the first column 31. This allows the first column 31 and the folding rod to be positioned above the surface of the main body 1 during conventional folding, without increasing the longitudinal footprint.

[0043] When the second column 32 slides relative to the first column 31, the connection position of the adjustment rod 33 and the second column 32 changes relative to the first column 31, and the overall length of the first column 31 and the second column 32 increases, causing the adjustment rod 33 to rotate relative to the second column 32, the adjustment rod 33 to rotate relative to the main body 1, and the first column 31 to rotate relative to the main body 1. In actual production, by designing the lengths of the first column 31, the second column 32, and the adjustment rod 33, it is possible to achieve a rotation of the first column 31, the second column 32, and the adjustment rod 33 relative to the main body 1 within a range of 0 to 180 degrees. Furthermore, the rotation angle of the first column 31 relative to the main body 1 can be controlled within a range of 0 to 90 degrees.

[0044] After the first column 31 and the second column 32 are rotated to a suitable angle, the user can lock the adjustment rod 33 and the first column 31 through the locking member 4 to keep the first column 31, the second column 32 and the adjustment rod 33 stable, so that the first column 31, the second column 32 and the adjustment rod 33 remain stable relative to the main body 1. In this state, the user can stably perform fitness exercises that meet his or her needs.

[0045] The locking member 4 is disposed transversely through the first column 31, with the end of the locking member 4 abutting against the second column 32. The locking member 4 is used to lock the first column 31 and the second column 32, thereby maintaining the stability of the deformation area 37. Locking methods include, but are not limited to, mechanical locking and electromagnetic locking. For example, the locking member 4 may be a fixing bolt that compresses the first column 31 and the second column 32 to achieve mechanical locking, a locking shaft that transversely penetrates the first column 31 and the second column 32 to achieve mechanical locking, and automatic locking may be achieved through electromagnetic control.

[0046] The following three implementation scenarios are provided for illustration.

[0047] In the first implementation scenario, the locking member 4 comprises a locking bolt and a locking nut. The locking bolt is radially inserted through the first column 31 and threadedly connected to the first column 31. The locking nut controls the rotation of the locking bolt. When the fixing bolt rotates toward the interior of the first column 31, the end of the fixing bolt abuts against the second column 32, pressing the second column 32 and the fixing bolt together, thereby locking the first column 31 and the second column 32. When the fixing bolt rotates in the opposite direction toward the interior of the first column 31, the pressure between the end of the fixing bolt and the surface of the second column 32 gradually decreases, allowing the second column 32 to slide relative to the first column 31. In the second implementation scenario, the second column 32 can have a positioning hole along its axis for the fixing bolt to pass through. The fixing bolt passing through the positioning hole achieves locking of the first column 31 and the second column 32. In the third implementation scenario, the second column 32 is provided with an electromagnetic locking device. When locking is required, the electromagnetic locking device locks the second column 32 to the first column 31.

[0048] In one embodiment, the main body 1 , the first column 31 , the second column 32 and the adjustment rod 33 enclose a deformation area 37 , and the shape of the deformation area 37 changes as the second column 32 slides on the first column 31 .

[0049] In a conventional exercise scenario, after the first column 31 is rotated to a suitable angle, the deformation area 37 formed by the first column 31, the second column 32, the adjustment rod 33 and the main body 1 is a triangular area. The user can lock the adjustment rod 33 and the first column 31 through the locking member 4. The stability of the triangle can be further improved to further enhance the stability of the first column 31, the second column 32 and the adjustment rod 33, thereby ensuring that the user can stably perform fitness exercises that meet their needs.

[0050] In one embodiment, when the second column 32 slides to the first position of the first column 31, the shape of the deformation area 37 is an acute triangle; when the second column 32 slides to the second position of the first column 31, the shape of the deformation area 37 is a right triangle; when the second column 32 slides to the third position of the first column 31, the shape of the deformation area 37 is an obtuse triangle; when the second column 32 slides to the fourth position of the first column 31, the main body 1, the first column 31, the second column 32 and the adjustment rod 33 are parallel to each other.

[0051] It should be supplemented that the first position, the second position, the third position and the fourth position can be used to represent a position range or at least one specific positioning point.

[0052] Several specific implementation scenarios are provided below to illustrate different forms and usage scenarios of the fitness device caused by the rotatable first column 31, the second column 32 and the adjustment rod 33 of the present application.

[0053] Figure 4 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 4 .

[0054] See also Figure 2 and Figure 4 In the first implementation scenario, the fitness device is in the first form. The deformation area 37 is formed by three sides. The first side is the side of the main body 1 between the first rotating member 34 and the second rotating member 35, which is of fixed length. The second side is the side of the adjustment rod 33, which is of fixed length. The third side is the side of the column between the first rotating member 34 and the third rotating member 36, which is of adjustable length.

[0055] When the second column 32 extends relative to the first column 31 and the first and second sides separate to the maximum angle, the distance between the first rotating member 34 and the third rotating member 36 reaches its maximum distance. The adjusting rod 33 and the first column 31 are placed above the main body 1 and as close to the main body 1 as possible. Specifically, the adjusting rod 33 and the first column 31 can be directly attached to the main body 1, or functional components provided on the adjusting rod 33 and the first column 31, such as the operating table 51 and the support legs 53, can be attached to the main body 1 to achieve the purpose of placing the adjusting rod 33 and the first column 31 on the main body 1.

[0056] In this configuration, the fitness device can be stored with a small footprint. Fitness-related components can also be connected to the first and second columns 31, 32 to facilitate other exercises. For example, a cushion 61 can be placed on the second column 32 to form a fitness bed for the user. Alternatively, the cushion 61 can be slidably mounted on the second column 32, allowing the user to perform other fitness exercises, such as Pilates, rowing, and waist-toning exercises, by controlling the cushion 61 to slide relative to the main body 1.

[0057] In actual working conditions, if the first side, the second side and the third side cannot be rotated to the same plane, the deformation area 37 is an obtuse triangle, that is, the third position mentioned above in the embodiment of the present application; if the first side, the second side and the third side can be rotated to the same plane, the main body 1, the first column 31, the second column 32 and the adjustment rod 33 are parallel to each other, that is, the fourth position mentioned above in the present application.

[0058] See also Figure 1In the second implementation scenario, the fitness device is in the second form. The deformation area 37 is formed by three sides. The first side corresponds to the side of the main body 1 between the first rotating member 34 and the second rotating member 35 and has a fixed length. The second side corresponds to the side of the adjustment rod 33 and has a fixed length. The third side corresponds to the side of the column between the first rotating member 34 and the third rotating member 36 and has an adjustable length.

[0059] The second column 32 slides relative to the first column 31, changing the length of the third side until the first column 31 is upright relative to the main body 1 to a value close to or reaching 90%. Furthermore, based on the user's preference, the vertical angle of the first column 31 and the second column 32 relative to the main body 1 can be set between 65° and 105°, i.e., the first position, second position, or third position described above in the embodiment of the present application. At this angle, the first column 31 and the second column 32 are locked by the locking member 4 to stabilize the deformation area 37, thereby forming a running space above the treadmill 2 for the user to run, and the user can run on the treadmill 2.

[0060] Figure 5 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 5 .

[0061] See also Figure 5 In the third implementation scenario, the fitness device is in the third form. The deformation region 37 is formed by three edges. The first edge corresponds to the edge of the main body 1 between the first rotating member 34 and the second rotating member 35 and has a fixed length. The second edge corresponds to the edge of the adjustment rod 33 and has a fixed length. The third edge corresponds to the edge of the column between the first rotating member 34 and the third rotating member 36 and has an adjustable length.

[0062] The second column 32 slides relative to the first column 31, changing the length of the third side. The length of the column portion that slides into the first column 31 can be between the first form and the second form, so that the first column 31 and the second column 32 are connected to the main body 1 at an angle and approach the main body 1. Specifically, the angle formed by the first column 31 and the second column 32 relative to the main body 1 can be within 65°, that is, the first position mentioned above in the embodiment of the present application. The first column 31 and the second column 32 are locked by the locking member 4. The pad 61 is slidably connected to the second column 32, and by holding the armrest 52, the knee or calf is placed on the pad 61, and other exercises such as crunches can be performed. In this form, the user can adjust the angle formed by the first column 31 and the second column 32 with the main body 1 according to their own ability to achieve the purpose of adjusting the difficulty of other exercises such as crunches, thereby making the fitness device more suitable for user needs.

[0063] Figure 6 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 6 .

[0064] See also Figure 6 In the fourth implementation scenario, the fitness device is in the fourth form. The deformation area 37 is formed by three sides. The first side corresponds to the side of the main body 1 between the first rotating member 34 and the second rotating member 35 and has a fixed length. The second side corresponds to the side of the adjustment rod 33 and has a fixed length. The third side corresponds to the side of the column between the first rotating member 34 and the third rotating member 36 and has an adjustable length.

[0065] Compared with the second and third forms, the second column 32 slides further into the first column 31. The side of the first column 31 is axially provided with an opening connected to the sliding groove 323 for the adjustment rod 33 to pass through the opening. At this time, the deformation area 37 is an obtuse triangle. The first column 31 is located outside the main body 1. The angle between the first column 31 and the main body 1 can be between 100 and 180 degrees, that is, the second column 32 is located in the third position or the fourth position mentioned in the present application. The first column 31 and the adjustment rod 33 are locked by the locking member 4 to perform other forms of fitness exercises. In actual working conditions, if the first side, the second side and the third side can be rotated to the same plane, the second column 32 is located in the fourth position. Otherwise, the second column 32 is located in the third position.

[0066] It can be understood that, in actual working conditions, the maximum angle that can be formed between the first column 31 and the main body 1 is related to the length of the second column 32, the length of the adjustment rod 33, and the position of the adjustment rod 33 on the second column 32. Usually, the actual rotation angle between the first column 31 and the main body 1 is 0 to 90°.

[0067] It should be noted that, to facilitate user angle control of the columns, the embodiment of the present application may include a corresponding angle scale on the second column 32, so that the user can adjust the angle using the angle scale. Furthermore, the present method may also utilize other drive components to control the sliding movement of the second column 32 relative to the first column 31, thereby achieving automatic control of the second column 32.

[0068] Figure 7 The schematic diagram of the implementation structure of a fitness device according to the embodiment of the present application is shown. Figure 7 .

[0069] See also Figure 2 、 Figure 3 and Figure 7 In one embodiment, the second column 32 includes a first column portion 321 and a second column portion 322. The first column portion 321 is slidingly connected to the first column 31. The second column 32 is located between the first column portion 321 and the second column portion 322 and a limiting member 38 is provided. The limiting member 38 is used to limit the second column portion 322 from sliding into the first column 31; the rotating shaft of the adjusting rod 33 is rotatably connected to the limiting member 38.

[0070] To limit the rotation angle of the column, the present application can provide a limiter 38 on the second column 32. The limiter 38 increases the transverse diameter of the second column 32 located between the first column portion 321 and the second column portion 322, thereby limiting the second column portion 322 from sliding into the support rod. The second column 32 is located in the middle of the second column 32 between the first column portion 321 and the second column portion 322, so that the rotation angle of the first column 31 relative to the main body 1 does not exceed 90 degrees.

[0071] The limiting member 38 can be a mounting hinge or a mounting sleeve for rotationally connecting the adjustment rod 33. When the limiting member 38 is a limiting sleeve, when the second post 32 slides relative to the first post 31 to the position of the limiting sleeve, the limiting sleeve abuts against the opening of the first post 31 because the diameter of the limiting sleeve is larger than the sliding groove 323, thus achieving the desired position. The limiting sleeve also allows the user to quickly adjust the fitness device to the second configuration, facilitating adjustment and installation.

[0072] Figure 8 Shows this application Figure 2 A is an enlarged schematic diagram.

[0073] See also Figure 2 and Figure 8 In one embodiment, a sliding groove 323 is provided on the second column 32, and the device also includes a support assembly 6, which includes a pad 61 and a sliding member 62. A gap is formed between the pad 61 and the running belt 2, and one end of the sliding member 62 is fixedly connected to the pad 61, and the other end of the sliding member 62 is connected to the sliding groove 323.

[0074] To facilitate the use of the fitness device, the fitness device provided in the embodiment of the present application has a symmetrically arranged sliding groove 323 on the second column 32, and the sliding member 62 includes a connecting shaft and a roller. The rollers are connected to the rollers on both sides of the pad 61 through the connecting shaft. The rollers are set in the sliding groove 323, and the pad 61 is slidably connected relative to the sliding groove 323 through the rollers.

[0075] The sliding groove 323 can be a T-shaped groove to prevent the roller from slipping out of the sliding groove 323 and to provide positioning and guidance for the roller. To prevent the limiter 38 from affecting the sliding of the roller within the sliding groove 323, a groove with an opening size equal to the sliding groove 323 can be provided on the limiter 38 to allow the pad 61 to slide through the limiter 38. The pad 61 can be mounted on one or more rollers. When multiple rollers are mounted on both sides of the pad 61, the multiple rollers can ensure that the surface of the pad 61 is always facing one side, preventing the pad 61 from rotating relative to the support assembly 6. Furthermore, to facilitate the first configuration of the fitness device, the pad 61 can slide relative to the main body 1. A gap of 3 to 30 cm is provided between the pad 61 and the treadbelt 2 to prevent friction between the pad 61 and the treadbelt 2.

[0076] In one embodiment, the second column 32 is made of a steel pipe, and a sliding groove 323 is opened along the axial direction of the steel pipe. The sliding groove 323 is also used for wiring. The steel pipe is provided with fixing holes 324 on both sides of the sliding groove 323, and the fixing holes 324 are used for connection to the operating table 51.

[0077] like Figure 8 As shown, the embodiment of the present application also provides a specific structure of a second column 32. The second column 32 of the embodiment of the present application can be made of a specific steel pipe fitting. Specifically, the steel pipe fitting is axially provided with a sliding groove 323 connected to the first column 31. The sliding groove 323 is used for the sliding member 62 to be embedded, so that the sliding member 62 can be slidably connected to the first column 31 and the second column 32 through the sliding groove 323, and the wires can be routed through the sliding groove 323 to achieve the purpose of connecting the operating table 51 and various components in the main body 1, so that the operating table 51 can control various components in the main body 1 to perform target operations.

[0078] The steel pipe fittings are provided with fixing holes 324 axially on both sides of the sliding groove 323. Various fixing parts such as fixing bolts 513 are connected to the fixing holes 324 to fix the operating table 51 to the second column 32, thereby achieving a stable connection between the main body 1, the first column 31, the second column 32 and the operating table 51.

[0079] In one embodiment, the end of the second column 32 is fixedly connected to the operating table 51; the first surface of the operating table 51 is provided with a control panel 511, and the second surface of the operating table 51 is provided with a flexible pad 512, and the first surface and the second surface are opposite to each other; the end of the second column 32 is rotatably connected to the armrest 52, and the armrest 52 is fixed to the second column 32 by a fixing member.

[0080] The end of the second column 32 is obliquely connected to the operating table 51; the first surface of the operating table 51 is provided with a control panel 511, and the second surface of the operating table 51 is provided with a flexible pad 512, and the first surface and the second surface are opposite to each other; when the second column 32 is located at the first position of the first column 31, the first surface of the operating table 51 is located above the second surface.

[0081] Specifically, an operating table 51 is laterally fixed to the end of the second column 32. A control panel 511 is provided on the first surface of the operating table 51 for the user to control the fitness device as a whole, including but not limited to the control of the speed and angle of the treadmill 2. A flexible pad 512 is provided on the second surface of the operating table 51. When the column is placed on the main body 1, the column is stably placed through the operating table 51 and the surface placed on the main body 1. In this state, the second surface faces the treadmill 2. A flexible pad 512 is provided on the second surface to facilitate the user to sit on the pad body 61 for exercise. The second surface supports the back of the user to ensure safety during exercise. According to the actual sports event, the back includes but is not limited to the head, neck, back, waist, etc.

[0082] Furthermore, an armrest 52 can be rotatably connected above the second column 32 for the user to hold. The armrest 52 is also fixed by a fixing part to limit rotation. The fixing part can also be a locking bolt and a locking nut. The fixing method is consistent with the fixing method of the locking part 4. It will not be repeated below. The user can rotate the armrest 52 to the required position and fix the armrest 52 relative to the second column 32 through the fixing part.

[0083] In one embodiment, there are two first columns 31 , and the two first columns 31 are symmetrically arranged on the main body 1 ; reinforcing rods are laterally connected to the two first columns 31 , and the surfaces of the reinforcing rods are covered with flexible materials.

[0084] To improve the stability between the two support assemblies 6, a connecting rod can be connected transversely to the two first columns 31 to reinforce the support assemblies 6. By protecting the connecting rod with a flexible material such as flexible cotton or rubber, the pad 61 can be held or supported by the user while exercising, improving safety.

[0085] See also Figure 7 and Figure 10 In one embodiment, a rope puller is further provided on the main body 1, and the rope puller includes a tension belt 71, and a hand-held portion 711 is provided at one end of the tension belt 71, and the pad body 61 includes a clamping portion 611 for the hand-held portion 711 to be clamped.

[0086] In an actual implementation scenario, when a user needs to perform rowing machine exercise, the user can sit on the cushion body 61 and repeatedly pull the resistance band 71 to achieve the purpose of exercise. A rope puller is provided on the main body 1 of the present application to facilitate the user to perform rowing machine exercise.

[0087] The main body 1 comprises a housing positioned in front of the treadbelt 2. A rope puller is positioned within the housing, and an opening is provided on the surface of the housing facing the treadbelt 2, through which the tension belt 71 extends. The housing has an inclined surface facing the treadbelt 2 and is provided with a footrest area 12 for the user to step on. This area is provided with friction particles to stabilize the user's foot. A counter panel 13 is located midway between the two footrests. This counter is connected to a detection device that detects the pulling of the tension belt 71. The counter counts the pulling frequency, which is then displayed on the counter panel 13, allowing the user to understand the pulling status.

[0088] In order to facilitate the user to hold the resistance band 71 while exercising on the rowing machine, and to prevent the resistance band 71 from being completely retracted into the shell, a hand-held portion 711 is provided at the end of the resistance band 71 away from the rope puller. The hand-held portion 711 is a hand-held rod. One end of the resistance band 71 is fixed to the middle of the hand-held rod. The hand-held rods are located on both sides of the resistance band 71 and are wrapped with rubber for easy grip. Correspondingly, the pad body 61 includes a clamping portion 611 for the hand-held portion 711 to be clamped. The clamping portion 611 can be located on the side or bottom of the pad body 61. The clamping portion 611 includes a limiting hook for the hand-held portion 711 to abut and a positioning opening provided on the limiting hook. The positioning opening is used for the resistance band to be embedded. The hand-held portion 711 is pressed into the limiting hook by the tension of the resistance band, thereby achieving the purpose of stably clamping the hand-held portion 711 on the pad body 61. Furthermore, due to the tension of the resistance band, the pad 61 can be positioned. When the fitness device is in the second configuration, the pad 61 can be prevented from moving relative to the support assembly 6 while the user is running, thereby maintaining the stability of the pad 61. Accordingly, when the user is performing an exercise that requires the pad 61 but is not rowing, the user can separate the stop hook from the handle 711 to facilitate movement of the pad 61, or maintain the stop hook from the handle 711 and use the resistance band 71 to prevent the pad 61 from sliding, thereby increasing the intensity of the exercise.

[0089] See also Figure 10 、 Figure 11 and Figure 12 The main body 1 is provided with a pulley 72 behind the footrest that can rotate relative to the main body 1, and the other end of the tension belt 71 is wound around the pulley 72. In another implementation scenario, the rope puller can be provided on the main body 1 behind the treadmill 2, and the rest of the structure can be adjusted accordingly. It will not be described in detail below.

[0090] To facilitate users in adjusting the running and rowing movements of the fitness device, the embodiment of the present application is also provided with a clutch-type switching switch for adjusting the running and rowing movements, including a frame 73, a driving member 74, a first transmission gear 741, a second transmission gear 742 and a switching assembly 75. The switching assembly 75 is used to switch between the first position and the second position of the frame 73. When the switching assembly 75 rotates to the first position, the kinetic energy of the driving member 74 is transmitted to the first actuator; when the switching assembly 75 rotates to the second position, the kinetic energy of the driving member 74 is transmitted to the second actuator.

[0091] Wherein, the first actuator can be one of the treadmill 2 or the pulley, and the second actuator can be the other. In the specific implementation scenario of this application, the first actuator is the treadmill 2, and the second actuator is the pulley.

[0092] The switch frame 73 is a square housing fixed to the main body 1 and arranged parallel to the pulley, located on one side of the pulley. The driving member 74 is a drive motor. The output shaft of the drive motor is installed on the frame 73 and can rotate relative to the frame 73. The output shaft is located on the side of the frame 73 facing away from the drive motor, and an output gear 743 is provided to ensure that the output gear 743 and the output shaft rotate synchronously. The first transmission gear 741 is located on one side of the output gear 743, with a gap between the first transmission gear 741 and the output gear 743, for transmission to the running belt 2; the second transmission gear 742 is located on the other side of the output gear 743, with a gap between the second transmission gear 742 and the output gear 743, for transmission to the second actuator. The switching assembly 75 is used to switch the assembly 75 including a first switching gear 751 and a second switching gear 752. When the switching assembly 75 rotates to the first position, the first switching gear 751 engages with the output gear 743 and the first transmission gear 741, and transmits the kinetic energy of the driving member 74 to the treadbelt 2, thereby realizing the rotation of the treadbelt 2 and providing a running motion; when the switching assembly 75 rotates to the second position, the second switching gear 752 engages with the output gear 743 and the second transmission gear 742, and transmits the kinetic energy of the driving member 74 to the pulley, thereby providing a rowing motion. Furthermore, the motor can be selected as a forward and reverse motor, and the damping effect of the tension belt can be achieved by setting the motor parameters. Alternatively, in another implementation, the second transmission gear 742 and the pulley can be connected by a clutch, and a damper can be set on the side of the pulley, so that when the tension belt is pulled out, the clutch separates the second transmission gear 742 and the pulley, and tension damping is provided by the damper. When the tension belt is recovered, the clutch transmits the power of the second transmission gear 742 to the pulley, thereby realizing the recovery of the tension belt.

[0093] In one embodiment, the switching assembly 75 further includes a rotating shaft 753 and a toggle member 754 . The rotating shaft 753 is rotatably connected to the frame 73 and can be disposed above the output gear 743 and between the first transmission gear 741 and the second transmission gear 742 . The toggle member 754 is laterally fixed to the end of the rotating shaft 753, and includes a toggle plate 7541 for rotationally connecting the first switching gear 751 and the second switching gear 752, and a toggle rod 7542 connected to the toggle plate 7541. The first switching gear 751 is located on one side of the rotating shaft 753, and the second switching gear 752 is located on the other side of the rotating shaft 753. There is a gap between the first switching gear 751 and the second switching gear 752, so that the first switching gear 751 and the second switching gear 752 can rotate with the rotation of the rotating shaft 753, thereby realizing the engagement and disengagement of the first switching gear 751 and the first transmission gear 741, and the engagement and disengagement of the second switching gear 752 and the second transmission gear 742, thereby realizing the switching of the fitness device to different exercise modes.

[0094] In one embodiment, a positioning slot 76 is defined on the frame 73. The toggle end of the toggle lever 7542 is inserted into and rotates in the positioning slot 76. When the toggle end rotates to the first end of the positioning slot 76, the toggle end is in the first position. When the toggle lever 7542 rotates to the second end of the positioning slot 76, the toggle end is in the second position. The positioning of the positioning slot 76 allows for more accurate switching of the switch.

[0095] To enhance the convenience of switching, an elastic member 77 may be provided. The first end of the elastic member 77 is fixed to the frame 73, and the second end of the elastic member 77 is connected to the toggle rod 7542, so that the switch assembly 75 always has a tendency to return to the first position or the second position. The elastic member 77 may be a spring.

[0096] Furthermore, to facilitate switching, since the movement switching of the fitness device of the present application is achieved by rotating the column, a pull cord 78 can be connected to the column and fixed to the bottom of the column. When the column is lowered, the bottom of the column rotates toward the output shaft, the pull cord 78 is released, the elastic member 77 returns to the second position, and the second transmission gear 742 engages with the output gear 743 via the second switching gear 752, transmitting power to the pulley to retract and extend the tension belt. When the column is raised, the bottom of the column rotates away from the output shaft, the pull cord 78 is tightened, pulling the toggle column to the first position, and the first transmission gear 741 engages with the output gear 743 via the first switching gear 751, transmitting power to the drive pulley of the treadmill 2, thereby rotating the treadmill 2.

[0097] Furthermore, this design eliminates the need for an additional locking device for locking the toggle lever 7542, further optimizing the structure of the fitness device. It should be understood that without this design, the toggle lever 7542 can be connected to a locking device to lock the toggle lever 7542. The locking device can be a tie rope, a hook, an expansion buckle, a column for binding the pull rope 78, etc., which will not be described in detail below.

[0098] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this disclosure can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solutions disclosed in this application can be achieved.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature.
