Description

Technical Field

[0001] This application relates to the field of office equipment technology, specifically a fitness office system. Background Technology

[0002] The fast pace of life, high intensity, and long working hours inevitably affect people's health; diseases such as cervical spondylosis, sciatica, and lumbar disc herniation are gradually shifting from affecting the elderly to younger people. To improve their health, people participate in outdoor activities and physical exercise outside of work hours; however, most office workers are limited by their work hours, preventing them from getting effective exercise, which can lead to illness and affect their work performance. Therefore, designing a fitness office system that allows for both work and appropriate exercise without disturbing others is a pressing issue that needs to be addressed.

[0003] Related technologies for fitness and office systems include, for example, the Chinese patent application of the applicant in this case, with publication number CN211130321U entitled "A Healthy Office System," which includes a height-adjustable work desk, a chair, and a treadmill installed under the work desk and extending under the chair. The work desk and chair are for users to use for work, while the treadmill allows users to exercise. Users can also use the treadmill to exercise their legs while sitting in the chair. Another example is the Chinese patent application with publication number CN106136573A entitled "A Multifunctional Treadmill Desk with User-Controlled Speed," which has a non-powered crawler treadmill installed under the height-adjustable desk frame, allowing users to exercise while working.

[0004] The aforementioned office equipment with fitness functions has some drawbacks in actual use: treadmills cannot be effectively integrated with office equipment, resulting in interference between office work and fitness activities; in addition, treadmills generally occupy a large area and are used for a relatively short period of time each day, so issues such as storage and cleaning of the floor beneath the treadmill cause many problems for users and hinder the promotion of this type of office equipment with fitness functions. Utility Model Content

[0027] In summary, compared with related technologies, the fitness office system proposed in this application has the following advantages: Firstly, this fitness office system integrates a treadmill into a work device, which can be used for studying and working, while the treadmill can be used for exercise. Therefore, this fitness office system combines fitness and office functions. Secondly, the treadmill is configured as two parts: a first platform and a second platform that can be rotated and unfolded via a rotating component. The first platform is rotatably connected to the support component of the work device. When the drive component drives the rotating component to rotate, it can cause the rotating component to move the second platform closer to the support component. The first and second platforms can be rotated and folded away from the support components, meaning that under the drive of the drive component, the first and second platforms can be rotated and folded closer to the support components, allowing the treadmill to be stored under the work platform of the work equipment. This frees up the ground space under the work platform, ensuring that the treadmill does not interfere with the user's study or work. When the user needs to exercise, the first and second platforms can be rotated and unfolded in opposite directions via the drive component. Therefore, this fitness office system allows office work and fitness to proceed without interference, and makes it convenient and simple to store the treadmill, as well as facilitating the cleaning of the ground under the treadmill.

[0052] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the embodiments of this application and are not intended to limit the scope of protection of the embodiments of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0053] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0054] In the embodiments of this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0055] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0056] See Figures 1 to 17 As shown in the figure, this application discloses a fitness office system, the structure of which includes a work device 1 and a treadmill 2. The work device 1 includes a support component 100 and a work platform 101 connected to the support component 100; the treadmill 2 is disposed below the work platform 101, and the head of the treadmill 2 is rotatably connected to the support component 100 through a pivot. Specifically, in this embodiment, see... Figure 1 As shown, the work device 1 is an office desk or study desk. The support assembly 100 includes two table legs, the upper ends of which are connected to the work platform 101, and the lower ends of which are respectively connected to table feet or bases. The treadmill 2 is located between the two table legs and placed on the ground. The head of the treadmill 2 is rotatably connected to the opposite inner walls of the two table legs via pivots on both sides. The work device 1 of this fitness office system can be used for studying, working, etc., while the treadmill 2 can be used for users to exercise. Therefore, this fitness office system integrates fitness and office functions, offering multiple uses.

[0057] Furthermore, in this embodiment, the worktable of the work device 1 has a support component 100 that is electrically lifting. That is, the support component 100 includes two lifting columns or lifting table legs. The lifting columns are equipped with a linear drive mechanism, such as a screw nut assembly, and a motor is installed on the top of the lifting column. The motor is connected to the linear drive mechanism inside the lifting column for transmission, which drives the linear drive mechanism to rotate and extend, thereby driving the lifting column to rise and fall, so as to adjust the height of the work platform 101.

[0058] In other embodiments, the working device 1 may also be a conference table, a bookcase, an office platform, etc.

[0059] As can be understood, the walking machine 2, also known as a treadmill, includes a walking platform or running platform. A frame is installed within the walking platform, and a drive motor 207, a front rotating roller 203, and a rear rotating roller 204 are mounted on the frame. A running belt 202 is sequentially wound around the front and rear rotating rollers 203 and 204. The drive motor 207 is connected to the front rotating roller 203 to drive its rotation, thereby moving the running belt 202. The drive motor 207 typically drives the front rotating roller 203 via a belt or chain. To provide users with different running belt speeds or exercise modes, the walking machine 2 also includes a control unit, which is electrically connected to the drive motor 207 to control its operation. The basic structure, operating principle, and working mode of this walking machine 2 are all relatively mature existing technologies, and will not be explained in detail in this embodiment.

[0060] It is easy to understand that the working device 1 can be configured as an electrically lifting working device, such as an electrically lifting table. This table typically includes a hand controller and a control unit, which are electrically connected. The control unit is also electrically connected to the motor that controls the lifting column. The hand controller has a control panel and a display panel. Similarly, the treadmill 2 also has a controller and a control panel. Therefore, in this embodiment, the controller of the treadmill 2 is integrated with the controller of the working device 1, and the control panel of the treadmill 2 is integrated with the hand controller or control panel of the working device 1. This means that the working device 1 and the treadmill 2 share the same controller and control panel. Users only need to operate one control panel to control the lifting of the working device 1 and the operation of the treadmill 2, making operation very convenient.

[0061] Understandably, the treadmill 2 is approximately 50-80 cm wide and 90-150 cm long, thus occupying a large area. Furthermore, given that the treadmill 2 is used for a relatively short period each day, its storage or folding is inconvenient when not in use. Additionally, its location below the work platform 101 may interfere with the user's normal work or study. Therefore, in this embodiment, the treadmill 2 is designed as a two-section foldable device, unfolded when in use and folded for storage when not in use. Specifically, see... Figure 1 and Figure 2As shown, the walking machine 2 includes a first walking platform 200 and a second walking platform 201. The head of the first walking platform 200 is rotatably connected to the support assembly 100, and the second walking platform 201 is rotatably connected to the first walking platform 200 via a rotating assembly 3. The angle between the first walking platform 200 and the second walking platform 201 is adjusted by power. The first walking platform 200 rotates around the connection point between the first walking platform 200 and the support assembly 100 as its rotation center. Simultaneously, the rollers 7 of the second walking platform 201 move on the support surface and approach the support assembly 100, thus achieving the folding of the first walking platform 200 and the second walking platform 201. (See also...) Figure 1 As shown, when the outer end of the second platform 201 rotates downward and toward the support component 100, the inner end of the second platform 201 is restricted and rotates upward, thereby causing the tail of the first platform 200 to rotate upward until the second platform 201 and the first platform 200 are completely retracted into the storage space formed by the support component 100 below the work platform 101; conversely, the second platform 201 rotates in the opposite direction, thereby causing the first platform 200 to rotate outward and unfold, and in the unfolded state, the tail of the first platform 200 is flush with the head of the second platform 201.

[0062] Further in this embodiment, see Figure 2 and Figure 3 As shown, the fitness office system also includes a drive component 4, which is mounted on the first walkway 200 and correspondingly positioned to the rotating component 3. The drive component 4 includes a worm gear 401 and a worm wheel 402 that is driven by the worm gear 401. The worm wheel 402 is driven by the rotating component 3 and is used to drive the rotating component 3 to rotate, thereby causing the second walkway 201 to rotate towards the support component 100 to fold or to rotate away from the support component 100 to unfold. The drive component 4 can drive the worm gear 401 to rotate, thereby causing the worm wheel 402 to rotate. The rotating worm wheel 402 synchronously drives the rotating component 3 to rotate, and the rotating component 3 can be linked to the rotation of the second walkway 201, thereby realizing the folding or unfolding operation of the treadmill 2.

[0063] It is understood that the drive assembly 4 also includes a housing 400. The worm 401 and worm wheel 402 of the drive assembly 4 are both located inside the housing 400. When installing the drive assembly 4, it is only necessary to connect the housing 400 to the frame of the first walkway 200. The assembly is simple and convenient.

[0064] In other embodiments, the drive component 4 can be mounted on the second platform 201 and the drive component can be connected to the rotating component in a transmission manner. During the process of the drive component driving the rotating component to rotate, the drive component and the second platform can rotate synchronously toward or away from the support component to retract or unfold.

[0065] In other embodiments, the worm 401 of the drive assembly 4 can be connected to the rotating assembly 3 via a transmission. In this case, the worm wheel serves as the power input end, and the rotation of the worm wheel drives the worm to rotate, thereby realizing the rotation of the rotating assembly and causing the second walkway to rotate and retract or rotate and unfold towards or away from the support assembly.

[0066] Besides adopting the structure of worm gear 401 and worm wheel 402, drive assembly 4 can also adopt other structures, such as in some embodiments, see [reference needed]. Figure 18 As shown, the drive assembly 4 includes at least one pair of meshing gears, one gear being rotatably connected to the first walkway 200 and the other gear being fixedly connected to the second walkway 201. A motor and a gearbox drive the gear on the first walkway 200, which in turn drives the gear on the second walkway 201, causing the second walkway 201 to rotate relative to the first walkway 200. Alternatively, the drive assembly 4 can also employ a linear actuator, see [reference needed]. Figure 19 As shown, one end of the linear actuator is hinged to the side of the first platform 200 near the second platform 201, and the other end is hinged to the side of the second platform 201 near the first platform 200. Both the first platform 200 and the second platform 201 are provided with mounting slots, and the linear actuator is disposed in the mounting slots. When the linear actuator extends, the second platform 201 rotates and unfolds relative to the first platform 200. When the linear actuator shortens, the second platform 201 rotates and folds relative to the first platform 200.

[0067] In this embodiment, the fitness office system comprises two parts: a first platform 200 and a second platform 201, which are rotatable and retractable via a rotating assembly 3. The first platform 200 is rotatably connected to the support assembly 100 of the work device 1. When the worm gear 402 or worm 401 of the drive assembly 4 drives the rotating assembly 3 to rotate, the rotating assembly 3 can cause the second platform 201 to rotate and retract towards the support assembly 100 or rotate and unfold away from the support assembly 100. In other words, under the drive of the drive assembly 4, the first platform 200... The first and second walkways 200 and 201 can rotate and retract towards the support component 100, thereby storing the treadmill 2 under the work platform 101 of the work device 1, thus freeing up the ground space under the work platform 101 and preventing the treadmill 2 from interfering with the user's study or work. When the user needs to exercise, the first and second walkways 200 and 201 can be rotated in opposite directions and unfolded through the drive component 4. Therefore, this fitness office system allows office work and fitness to not interfere with each other, and makes it convenient and simple to store the treadmill 2, and also facilitates cleaning of the ground under the treadmill 2.

[0068] It is easy to understand that the drive assembly 4 uses the transmission cooperation of worm gear 401 and worm wheel 402 to drive the rotation of the rotating assembly 3. Because worm gear 401 and worm wheel 402 have a certain self-locking ability, when the first platform 200 and the second platform 201 are in a fully retracted or half-retracted state, the self-locking action of worm gear 401 and worm wheel 402 in the drive assembly 4 prevents the first platform 200 and the second platform 201 from accidentally unfolding, thus ensuring high safety in use.

[0069] Further in this embodiment, see Figure 1 and Figure 2 As shown, a roller 7 is connected to the bottom of the second platform 201 at the end furthest from the first platform 200. This roller 7 is positioned so that when the drive assembly 4 rotates the second platform 201 downwards towards the support assembly 100 via the rotation assembly 3, the roller 7 contacts the ground, facilitating the rotation and folding of both the second and first platforms 200. It also facilitates the rotation and unfolding of the second and second platforms 201 when the drive assembly 4 drives them. The roller 7 also prevents noise from friction between the second platform 201 and the ground during unfolding or folding.

[0070] It is understood that the drive component 4 in the above embodiments can be manually driven or electrically driven. When manually driven, a crank handle can be connected to the worm gear 401 or worm wheel 402. By turning the crank handle, the worm gear 401 or worm wheel 402 is driven to rotate, thereby driving the rotating component 3 to rotate. In this embodiment, in order to make the folding or unfolding of the treadmill 2 more intelligent and without the need for manual operation, the drive component 4 is set to be electrically driven. Specifically, the fitness office system is also equipped with a first motor 5, which is installed on the first platform 200 and is connected to the drive component 4 for transmission, and is used to drive the drive component 4 to rotate, thereby driving the rotating component 3 to rotate. Therefore, the user only needs to control the first motor 5 to rotate forward and reverse to drive the rotating component 3 to rotate, thus completing the folding or unfolding operation of the treadmill 2.

[0071] In other embodiments, when the drive assembly 4 is disposed on the second walkway 201, the first motor 5 may also be disposed on the second walkway 201.

[0072] In some embodiments, if the width of the walking machine 2 is small, the rotating component 3 and the driving component 4 can be set as one set respectively; however, in this embodiment, in order to make the rotation of the second walking platform 201 more stable when rotating in conjunction with the first walking platform 200 to close or unfold, in this embodiment, the rotating component 3 and the driving component 4 are set as two sets respectively. The two sets of rotating components 3 are respectively arranged on both sides of the walking machine 2, and the two sets of driving components 4 are respectively arranged corresponding to the two sets of rotating components 3. The worm gears 402 of the two sets of driving components 4 are respectively driven connected to the two sets of rotating components 3, and the first motor 5 is respectively driven connected to the worm gears 401 of the two sets of driving components 4.

[0073] For example, see Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first walkway 200 has a first frame 205, and the second walkway 201 has a second frame 206. Both the first frame 205 and the second frame 206 are rectangularly arranged by splicing metal profiles. Both sides of the first frame 205 and the second frame 206 have side frames or side rods extending along the length of the treadmill 2. When the treadmill 2 is fully extended, the tail end of the first frame 205 is aligned with the head end of the second frame 206 to form a complete frame. Two sets of rotating components 3 are respectively arranged on both sides of the treadmill 2 and located at the splicing point of the first frame 205 and the second frame 206. Each set of rotating components 3 is connected to the opposite ends of the side rods of the first frame 205 and the second frame 206. Two sets of driving components 4 are respectively arranged on both sides of the treadmill 2 and are respectively arranged corresponding to the two sets of rotating components 3. The two sets of driving components 4 are respectively connected to the side rods on both sides of the first frame 205 and located at the end of the side rods near the second frame 206. The worm gear 402 of each drive assembly 4 is driven by the corresponding rotating assembly 3.

[0074] In other embodiments, the two sets of drive components can also be connected to the side rods on both sides of the second frame and located at the end of the side rods closer to the first frame. This also enables the drive components to drive the rotating components to rotate, thereby causing the second walkway to rotate and retract or rotate and unfold in conjunction with the first walkway.

[0075] For further examples, see Figure 2 , Figure 4 and Figure 7As shown, the first motor 5 is connected to the worm gears 401 of two sets of drive components 4 respectively. Specifically, a first transmission rod 500, a second transmission rod 501, a third transmission rod 502 and several first gearboxes 503 are provided between the first motor 5 and the two drive components 4. The first gearboxes 503 are fixedly connected to the first frame 205 by fasteners. The first transmission rods 500 and 501 are arranged along the width direction of the first walkway 200 and the third transmission rod 502 is arranged along the length direction of the first walkway 200. One end of the first transmission rod 500 is connected to the first motor 5, and the other end of the first transmission rod 500 is connected to one end of the third transmission rod 502 through the first gearboxes 503. The other end of the third transmission rod 502 is connected to the worm gears 401 of one set of drive components 4. One end of the second transmission rod 501 is connected to the third transmission rod 502 through the first gearboxes 503, and the other end of the second transmission rod 501 is connected to the worm gears 401 of another drive component 4 through the first gearboxes 503. This arrangement not only allows the first motor 5 to drive the two sets of drive components 4 to rotate separately, but also balances the weight on both sides of the first walkway 200. In this embodiment, the first transmission rod 500, the second transmission rod 501, and the third transmission rod 502 are all metal rods with polygonal cross-sections, which facilitates connection and power transmission.

[0076] In some implementations, see Figure 20 As shown, a second transmission rod 501, a fourth transmission rod 504, and several first gearboxes 503 are provided between the first motor 5 and the two drive components 4. The second transmission rod 501 is arranged along the width direction of the first walkway 200, and the fourth transmission rod 504 is arranged along the length direction of the first walkway 200. One end of the fourth transmission rod 504 is connected to the first motor 5, and the other end is connected to the worm gear 401 of one drive component 4. One end of the second transmission rod 501 is connected to the fourth transmission rod 504 through the first gearbox 503, and the other end is connected to the worm gear 401 of another drive component through the first gearbox 503. That is, in this embodiment, the first transmission rod 500 and the third transmission rod 502, as well as the first gearbox 503 located between the first transmission rod 500 and the third transmission rod 502, are eliminated. The first motor 5 can be directly connected to the lower first gearbox 503 through the fourth transmission rod 504.

[0077] Further in this embodiment, see Figure 7 and Figure 8As shown, a driving gear 403 and a driven gear 404 are rotatably connected within the housing 400 of one of the drive components 4. The driven gear 404 is coaxially and fixedly connected to the worm gear 401 of the drive component 4. The first motor 5 is driven by the driving gear 403, and the driven gear 404 is driven by the worm gear 401 of the other drive component 4. In this embodiment, the driven gear 404 and the worm gear 401 of the drive component 4 are coaxially arranged, and the rotation of the driven gear 404 causes the worm gear 401 of the drive component 4 to rotate synchronously. The third transmission rod 502 is coaxially connected to the driving gear 403, driving the driving gear 403 to rotate. One end of the second transmission rod 501 is driven by the shaft of the driven gear 404 through the first gearbox 503, and the other end of the second transmission rod 501 is driven by the worm gear 401 of the other drive component 4 through the gearbox.

[0078] In this embodiment, see Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the drive assembly 4 is connected to the first walkway 200, and the first motor 5 is also fixedly connected to the first walkway 200. Each rotating assembly 3 includes a first rotating plate 300 and a first connecting rod 301. The first connecting end of the first rotating plate 300 is connected to the worm gear 402 of the drive assembly 4 and rotates synchronously with the worm gear 402. The second connecting end of the first rotating plate 300 is rotatably connected to the first end of the first connecting rod 301, and the second end of the first connecting rod 301 is rotatably connected to the second frame 206 of the second walkway 201. In this embodiment, the first rotating plate 300 is a triangular metal plate with three connecting ends at its three corners. A polygonal shaft 305 is fixedly connected to the first connecting end of the first rotating plate 300. The polygonal shaft 305 is coaxially connected to the shaft of the worm gear 402. When the worm gear 402 rotates, it synchronously drives the first rotating plate 300 to rotate circumferentially around the axis of the polygonal shaft 305 or the axis of the shaft of the worm gear 402. Since the second connecting end of the first rotating plate 300 is rotatably connected to the second platform 201 through the first connecting rod 301, the second platform 201 can rotate to retract or unfold.

[0079] In the foregoing embodiments, see again Figure 7 , Figure 8 and Figure 9As shown, each rotating assembly 3 also includes a second rotating plate 302 and a second connecting rod 303. The second rotating plate 302 is connected to the first rotating plate 300 via a positioning rod 304 and can rotate synchronously with the first rotating plate 300. The first connecting end of the second rotating plate 302 is rotatably connected to the second frame 206 of the second walkway 201, and the second connecting end of the second rotating plate 302 is rotatably connected to the first end of the second connecting rod 303. The second end of the second connecting rod 303 is rotatably connected to the first frame 205 of the first walkway 200. The second rotating plate 302 is also a triangular metal plate with three connecting ends at its three corners. The second rotating plate 302 is fixedly connected to the first rotating plate 300 through the positioning rod 304, so that the second rotating plate 302 and the first rotating plate 300 rotate synchronously. That is, when the driving component 4 drives the first rotating plate 300 to rotate, the second rotating plate 302 rotates synchronously with the first rotating plate 300, thereby linking the second connecting rod 303 to rotate, so that the second platform 201 rotates to retract or unfold relative to the first platform 200.

[0080] It is understood that, in this embodiment, see Figure 8 , Figure 9 , Figure 14 and Figure 15 As shown, each rotating assembly 3 includes a first rotating plate 300, a first connecting rod 301, a second rotating plate 302, and a second connecting rod 303. The first rotating plate 300 is hinged to the first connecting rod 301, the first connecting rod 301 is hinged to the second frame 206 of the second walkway 201, and the second rotating plate 302 is hinged to the second connecting rod 303. The second connecting rod 303 is hinged to the first frame 205 of the first walkway 200. The worm gear 402 of the driving assembly 4 is drivenly connected to the first rotating plate 300, and the first rotating plate 302... The first platform 200 and the second rotating plate 302 rotate synchronously. Since both the first platform 200 and the second platform 201 have a certain thickness, this arrangement not only avoids interference between them during rotation, making the rotation smoother, but also results in a compact structure. The first platform 200 and the second platform 201 mutually constrain each other, preventing damage to the running belt 202 mounted on the first platform 200 and the first platform 201 due to excessive relative movement at the connection point when the second platform 201 rotates relative to the first platform 200. Furthermore, this arrangement of the rotating assembly 3 allows the second platform 201 to rotate to the same plane as the first platform 200, or allows both the second platform 201 and the first platform 200 to rotate to a vertical position and fit together. Furthermore, the projections of the first connecting rod 301 and the second connecting rod 303 along the width direction of the treadmill 2 are symmetrically arranged about the perpendicular bisector of the line connecting their projections. This arrangement of the rotating assembly 3 improves the stability of the first and second walkways 200 when they are folded or unfolded. Further, in this embodiment, see... Figure 8 , Figure 9 , Figure 12 and Figure 13 As shown, the first platform 200 has a first positioning hole 208 at one end near the second platform 201, which engages with the positioning rod 304. The second platform 201 has a second positioning hole 209 at one end near the first platform 200, which also engages with the positioning rod 304. When the second platform 201 is rotated to its fully extended state, the first positioning hole 208 and the second positioning hole 209 engage with the positioning rod 304. The positioning posts on the first rotating plate 300 and the second rotating plate 302, when the second platform 201 is rotated to its fully extended state, allow the first positioning hole 208 on the first platform 200 and the second positioning hole 209 on the second platform 201 to engage with these positioning posts, thereby achieving positioning of the first platform 200 and the second platform 201 during deployment and preventing incomplete deployment.

[0081] Furthermore, in this embodiment, the head sides of the first platform 200 are rotatably connected to two lifting columns via rotating seats 210. When the first platform 200 and the second platform 201 are in a fully retracted state, they are located or stored within the storage space formed between the two lifting columns. See details. Figure 10 As shown, when the first platform 200 and the second platform 201 of the treadmill 2 are in the fully retracted state, the second platform 201 is located within the space defined by the two lifting columns. This allows the space under the work platform 101 to be completely released, which is beneficial for users to work or study in front of the office equipment.

[0082] See Figure 11 , Figure 12 and Figure 13 As shown, when the first platform 200 and the second platform 201 of the treadmill 2 are in the fully folded state, the first platform 200 and the second platform 201 are arranged in parallel relative to each other, which makes the first platform 200 and the second platform 201 smaller in size and easier to store when in the fully folded state.

[0083] In this embodiment, the drive motor 207 and the front rotating roller 203 of the walking machine 2 are mounted on the first platform 200, and the rear rotating roller 204 is mounted on the second platform 201. A running belt 202 is wound around the front rotating roller 203 and the rear rotating roller 204. It is understood that when the first platform 200 and the second platform 201 of the walking machine 2 are fully extended and the walking machine 2 is operating normally, the running belt 202 is in a taut state. This will inevitably affect the rotation and retraction of the first platform 200 and the second platform 201, and may even prevent the first platform 200 and the second platform 201 from rotating relative to each other. Therefore, when the second platform 201 drives the first platform 200 to rotate and retract, the running belt 202 must first be in a slack state to provide rotational margin for the rotation of the first platform 200 and the second platform 201, so that the first platform 200 and the second platform 201 can rotate and retract smoothly. Therefore, in this embodiment, see... Figure 2 , Figure 16 and Figure 17 As shown, the rear rotating roller 204 is slidably connected to the second platform 201 along its length. A drive structure is connected to the second platform 201, and the drive structure is driven to slide the rear rotating roller 204 to adjust the tension of the running belt 202. That is, when the first platform 200 and the second platform 201 rotate relative to each other and retract, the drive structure first drives the rear rotating roller 204 to slide a certain displacement closer to the first platform 200 to loosen the running belt 202. Then, the first motor 5 is started to drive the drive assembly 4 to rotate, so that the second platform 201 and the first platform 200 rotate and retract simultaneously. When the first platform 200 and the second platform 201 rotate relative to each other and unfold to the fully unfolded state, the running belt 202 is still in a slack state. Therefore, the running belt 202 can be tensioned by driving the rear rotating roller 204 to slide a certain displacement away from the first platform 200 through the drive structure. At the same time, if the user finds that the running belt 202 is slack during fitness exercise, the tension of the running belt 202 can also be adjusted through the drive structure.

[0084] Further in this embodiment, see Figure 16As shown, the drive structure includes at least one set of lead screw and nut assemblies 8. The fitness office system also includes a second motor 6 connected to the second platform 201. The second motor 6 drives the rear rotating roller 204 to slide through the lead screw and nut assembly 8, so as to automatically adjust the tension of the running belt 202 when the second platform 201 rotates to unfold or retract. The control circuit of the second motor 6 is electrically connected to the controller of the walking machine 2. When the second platform 201 rotates to retract, the controller automatically controls the second motor 6 to move, so that the second motor 6 drives the rear rotating roller 204 to slide towards the first platform 200 through the lead screw and nut assembly 8, thereby slackening the running belt 202. Similarly, when the running belt 202 is tensioned, the controller automatically controls the second motor 6 to move, so that the second motor 6 drives the rear rotating roller 204 to slide away from the first platform 200 through the lead screw and nut assembly 8, thereby tensioning the running belt 202. Thus, the tension of the running belt 202 is automatically adjusted during the rotation, retraction, or unfolding of the first platform 200 and the second platform 201.

[0085] For example, see Figure 16 and Figure 17 As shown, the frames on both sides of the second walkway 201 are provided with grooves 211 along the length direction. Slider blocks 212, connected to the rear rotating roller 204, are slidably connected within each groove 211. Two sets of lead screw and nut assemblies 8 are respectively arranged within the two grooves 211. The transmission nut 800 of each lead screw and nut assembly 8 is connected to the slider 212 within the groove 211. The second motor 6 is connected to the lead screw of each of the two lead screw and nut assemblies 8. The second motor 6 drives the lead screw of the lead screw and nut assembly 8 to rotate, causing the slider 212 within the groove 211 to slide along the length of the lead screw. This, in turn, causes the rear rotating roller 204 to slide on the second walkway 201 to adjust the tension of the running belt 202. This design is simple and makes the rear rotating roller 204 slide more smoothly on the second walkway 201.

[0086] In some embodiments, the tension of the running belt 202 can also be adjusted manually. The drive structure includes at least one set of screw and nut assemblies 8. The rear rotating roller 204 is fixedly connected to the nut in the screw and nut assembly 8. The rotation of the screw causes the rear rotating roller 204 to move. The screw can be rotated manually by a crank or knob. Alternatively, the tension of the running belt 202 can be automatically adjusted by setting a spring. That is, a spring is connected to the rear rotating roller 204. When the first platform 200 and the second platform 201 are folded, the spring is compressed, and the rear rotating roller 204 moves closer to the first platform 200, thereby slackening the running belt 202. When the first platform 200 and the second platform 201 are unfolded, the spring is opened, and the rear rotating roller 204 moves away from the first platform 200, thereby tensioning the running belt 202.

[0087] In this embodiment, the second motor 6 is mounted on one side of the second frame 206 of the second walkway 201. A first drive rod 600, a second drive rod 601, a third drive rod 602, and several second gearboxes 603 are provided between the second motor 6 and the two sets of drive structures. The first drive rod 600 and the second drive rod 601 are arranged along the width direction of the second walkway 201, and the third drive rod 602 is arranged along the length direction of the second walkway 201. One end of the first drive rod 600 is connected to the second motor 6, and the other end of the first drive rod 600 is connected to one end of the third drive rod 602 via a second gearbox 603. The other end of the third drive rod 602 is connected to a lead screw and nut assembly 8 of one drive structure and a second drive rod 601 via another second gearbox 603. The other end of the second drive rod 601 is then connected to a lead screw and nut assembly 8 of another drive structure via a second gearbox 603. This arrangement not only allows the second motor 6 to drive the two sets of drive structures separately but also balances the weight on both sides of the second walkway 201. In this embodiment, the first drive rod 600, the second drive rod 601, and the third drive rod 602 are all metal rods with polygonal cross-sections, which facilitates connection and power transmission.

[0088] To further improve the stability of the first walkway 200 and the second walkway 201 during rotational retraction or rotational deployment, and to avoid wear on the running belt 202 and the first walkway 200 and the second walkway 201, in this embodiment, see... Figure 2 , Figure 21 and Figure 22 As shown, the treadmill 2 also includes a film 9, which is generally a plastic film, such as a film made of PVC material. Its width is adapted to the width of the movement surface of the treadmill 2. The film 9 is set between the running belt 202 and the two platforms, or the film 9 is divided into two independent parts and set on the first platform 200 and the second platform 201 on the inner side of the running belt 202 respectively. Specifically, in one embodiment, the first end of the film 9 is fixedly connected to the first platform 200, and the second end passes around the upper surface of the first platform 200 and the upper surface of the second platform 201 in sequence and is connected to the elastic element 10 at the bottom of the second platform 201. The elastic element 10 is used to keep the film 9 in a taut state during the rotation and retraction or rotation and unfolding of the first platform 200 and the second platform 201. In this embodiment, a roller 213 is connected to the end of the second platform 201 away from the first platform 200. The first end of the film 9 is fixedly connected to the upper surface of the first platform 200, and the second end passes through the upper surface of the first platform 200, the upper surface of the second platform 201 and the roller 213 in sequence before being connected to the elastic element 10 at the bottom of the second platform 201.

[0089] It is understood that a film 9 is provided between the first platform 200, the second platform 201, and the running belt 202. The film 9 mainly covers the upper side of the first platform 200 and the second platform 201. A part of the film 9 is directly fixedly connected to the first platform 200, and another part is connected to the elastic element 10 provided on the lower side of the second platform 201. The elastic element 10 is used to tighten the film 9. When the first platform 200 and the second platform 201 are folded, the first platform 200 and the second platform 202 are connected to the running belt 202. The area of ​​the film 9 on the upper side of the second platform 201 is increased, and the elastic element 10 is stretched to adapt to the situation when the first platform 200 and the second platform 201 are folded, so that the stability of the first platform 200 and the second platform 201 is better when folded or unfolded. Furthermore, by having the film 9 in contact with the running belt 202, wear and tear on the running belt 202 itself and on the first platform 200 and the second platform 201 is avoided, and friction on the running belt 202 is reduced, thus extending the service life of the running belt 202.

[0090] Further in this embodiment, see Figure 2 and Figure 22 As shown, to ensure the film 9 is evenly tensioned by the elastic element 10, a slide rail 214 is provided along the length direction at the bottom of the second platform 202. A clamping plate 215 is slidably connected to the slide rail 214, and the clamping plate 215 is fixedly connected to the second end of the film 9. One end of the elastic element 10 is connected to the second platform 201, and the other end is connected to the clamping plate 215. Specifically, two slide rails 214 are provided along the length direction on both sides of the bottom of the second platform 201. The clamping plate 215 is arranged along the width direction of the second platform 201 and is slidably fitted on the two slide rails 214. The elastic element 10 consists of two tension springs, which are arranged in parallel and both are arranged along the length direction of the second platform 201. One end of the tension spring is connected to the clamping plate 215, and the other end of the tension spring is fixedly connected to the crossbar at the bottom of the second platform 201.
