Description
Technical Field
[0001] This application relates to the field of fitness equipment technology, specifically a folding treadmill. Background Technology
[0002] The fast pace of life, high intensity, and long working hours inevitably affect people's health. The age of onset for diseases such as cervical spondylosis, sciatica, and lumbar disc herniation is gradually decreasing. Therefore, people often use fitness equipment or outdoor sports to improve their physical fitness during their spare time at the office. Currently, most office workers are limited by their work hours and find it difficult to exercise outdoors. To ensure effective physical activity, they often place treadmills next to their desks and use them for exercise after a certain period of work.
[0003] Treadmills, also known as walking machines, are relatively large, with long running platforms that take up considerable space during transportation and storage. Therefore, most treadmills are designed to be foldable. The running platform is folded to save space during transport or storage, and unfolded horizontally for use. This particular foldable treadmill structure includes two foldable running platforms. The two frames of the two running platforms utilize a folding structure with sliders, sliding columns, and sliding grooves at their opposite ends to achieve the folding or unfolding of the two running platforms. For example, the Chinese patent application with publication number CN219307832U and titled "A Treadmill Running Platform Folding Mechanism" has a structure including two base frames and a hinge disposed between the two base frames. The hinge includes two hinge bodies, each of which includes a hinge seat, a hinge shaft, a chain piece, and a sliding shaft. One end of the hinge seat of a single hinge body is inserted into the opening of the base frame and is fixed by bolts that pass vertically through the base frame and the hinge seat. The upper side of the unfixed end of the two hinge seats is provided with a hinge shaft, and the two hinge seats are also provided with an upwardly inclined strip groove. The sliding shaft is inserted into the strip groove. The chain piece is arc-shaped and located outside the hinge seat. One end of the chain piece is movably fixed to the hinge shaft, and the other end is movably fixed to the sliding shaft of the other hinge seat. At the same time, the middle part of the chain piece of the two hinge bodies is fixed by a connecting shaft.
[0004] The folding structure of the walking machine mentioned above has some defects in actual use: during the folding process of the running platform, due to the unavoidable sliding gap between the sliding shaft and the strip groove, there is a relative shaking phenomenon during the folding process, resulting in poor structural stability and poor user experience. Utility Model Content
[0005] The technical problem to be solved by this application is to overcome the defects of the above-mentioned related technologies and provide a folding walking machine that can eliminate or partially eliminate shaking during the folding process, has good structural stability, and provides a good user experience.
[0006] The technical solution of this application is to provide a folding walking machine having the following structure: including... The walkway body includes a first walkway and a second walkway. The frame end of the first walkway is connected to a first fixing plate, and the frame end of the second walkway is connected to a second fixing plate opposite to the first fixing plate. A folding assembly, connecting the two fixed plates respectively, is used to allow the second walkway to rotate relative to the first walkway. The folding assembly includes an outer main connecting rod and an outer auxiliary connecting rod disposed on the outer side of the fixed plates, and an inner main connecting rod and an inner auxiliary connecting rod disposed on the inner side of the fixed plates. The outer main connecting rod is hinged to the middle of the inner main connecting rod. One end of the outer main connecting rod is hinged to the first fixed plate, and the other end of the outer main connecting rod is hinged to the lower end of the outer auxiliary connecting rod. The upper end of the outer auxiliary connecting rod is hinged to the second fixed plate. One end of the inner main connecting rod is hinged to the second fixed plate, and the other end of the inner main connecting rod is hinged to the lower end of the inner auxiliary connecting rod. The upper end of the inner auxiliary connecting rod is hinged to the first fixed plate.
[0007] In some embodiments, the hinge is a connection between a pin and a pin hole.
[0008] In some embodiments, the outer main connecting rod and the inner main connecting rod are hinged at the middle by a positioning shaft, and the first fixing plate is provided with a first positioning groove at one end near the second fixing plate, and the second fixing plate is provided with a second positioning groove at one end near the first fixing plate. When the second platform rotates to the unfolded state relative to the first platform, the first positioning groove and the second positioning groove are respectively engaged with the positioning shaft.
[0009] In some embodiments, both the outer main connecting rod and the inner main connecting rod have two rotating arms arranged at a certain included angle: a first rotating arm and a second rotating arm. The first rotating arm of the outer main connecting rod is hinged to the first fixed plate, and the second rotating arm of the outer main connecting rod is hinged to the lower end of the outer auxiliary connecting rod. The first rotating arm of the inner main connecting rod is hinged to the second fixed plate, and the second rotating arm of the inner main connecting rod is hinged to the lower end of the inner auxiliary connecting rod.
[0010] In some embodiments, when the second walkway is rotated to an unfolded state relative to the first walkway, the projections of the outer main connecting rod and the inner main connecting rod along the width direction of the walkway body are symmetrically arranged about the perpendicular bisector of the line connecting their projections.
[0011] In some embodiments, the first fixing plate protrudes outward from the end of the first walkway frame, and the second fixing plate protrudes outward from the end of the second walkway frame, so that a rotation gap is formed between the end of the frame of the first walkway and the end of the frame of the second walkway for the folding assembly to rotate.
[0012] In some embodiments, a first plate is connected to the top of the frame of the first walkway, and a second plate is connected to the top of the frame of the second walkway, with an installation gap between the first plate and the second plate.
[0013] In some embodiments, the tops of the first plate and the second plate are connected to a wear-resistant layer covering the first plate and the second plate.
[0014] In some embodiments, the treadmill further includes a running belt, a drive motor, a front rotating roller connected to the first walking platform and driven by the drive motor, and a rear rotating roller connected to the second walking platform, wherein the running belt is sequentially wound around the front rotating roller and the rear rotating roller.
[0015] In some embodiments, the frame end of the first walkway is connected to a first cover covering the outside of the first fixed plate, and the frame end of the second walkway is connected to a second cover covering the outside of the second fixed plate.
[0016] In summary, compared with related technologies, the folding walking machine of this application has the following advantages: The folding walking machine includes a first platform and a second platform, wherein the second platform can be rotated relative to the first platform through a folding assembly, thereby allowing the platform body to be rotatably folded or unfolded; the folding assembly of the folding walking machine is composed of an outer main connecting rod, an outer auxiliary connecting rod, an inner main connecting rod, and an inner auxiliary connecting rod, and the four connecting rods are respectively hinged to the fixed plates of the first platform and the second platform, which not only has good structural stability, but also replaces the sliding connection between the sliding shaft and the strip through groove in related technologies, thus achieving high hinge precision. It maintains good fit and levelness between the end faces of the first platform and the second platform after unfolding, and also basically eliminates the shaking phenomenon caused by gaps when the platform body is rotated and folded. Therefore, the folding walking machine can eliminate or partially eliminate the shaking during the folding process and has good structural stability, resulting in a better user experience.

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.
[0034] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0035] See Figures 1 to 13 As shown in the figure, this application discloses a folding treadmill, also known as a walking machine. Its structure includes a platform body, comprising a first platform 1 and a second platform 2. The first platform 1 has a frame end connected to a first fixing plate 101, and the second platform 2 has a frame end connected to a second fixing plate 201 opposite to the first fixing plate 101. A folding assembly 5 is provided between the first fixing plate 101 and the second fixing plate 201. This folding assembly 5 connects to the two fixing plates respectively, allowing the second platform 2 to rotate relative to the first platform 1, so that the platform body is in an unfolded or folded state. In the unfolded state, the first platform 1 and the second platform 2 are horizontally aligned and spliced together to form a complete platform body, allowing the user to perform walking or running training. In the folded state, the second platform 2 rotates and folds to be located above the first platform 1 and stacked with it, allowing the treadmill to be stored away to save space.
[0036] For example, see Figure 1 , Figure 2 , Figure 3 , Figure 7 and Figure 8As shown, the first walkway 1 has a first frame 100, and the second walkway 2 has a second frame 200. Both the first frame 100 and the second frame 200 are rectangularly arranged by splicing metal profiles. Both sides of the first frame 100 and the second frame 200 have side bars extending along the length of the walkway body, and the two side bars are fixed together by crossbars. When the treadmill is fully extended, the tail end of the first frame 100 and the head end of the second frame 200 form a complete frame. Two first fixing plates 101 and two second fixing plates 201 are provided. The two first fixing plates 101 are respectively fixedly connected to the ends of two side rods on both sides of the tail end of the first frame 100 by fasteners. The two second fixing plates 201 are respectively fixedly connected to the ends of two side rods on both sides of the head end of the second frame 200 by fasteners. Two sets of rotating components are also provided, and are respectively provided on both sides of the walkway body and located at the splicing point of the first frame 100 and the second frame 200. Each set of rotating components is respectively connected to the first fixing plate 101 at the end of the side rod of the first frame 100 and the second fixing plate 201 at the end of the side rod of the second frame 200.
[0037] Understandably, the folding treadmill also includes a drive motor 4, a front rotating roller 400, and a rear rotating roller 401, with a running belt 3 sequentially wound around the front rotating roller 400 and the rear rotating roller 401. The drive motor 4 is mounted on a frame inside the treadmill body and is connected to the front rotating roller 400 for driving the front rotating roller 400 to rotate, thereby driving the running belt 3 to move. The drive motor 4 typically drives the front rotating roller 400 to rotate via a belt or chain.
[0038] For example, see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the drive motor 4 and the front rotating roller 400 are mounted on the first frame 100 inside the first platform 1, and the drive motor 4 and the front rotating roller 400 are located at the head of the first frame 100, that is, at the end of the first frame 100 away from the second frame 200; the rear rotating roller 401 is rotatably connected to the second frame 200 inside the second platform 2, and is located at the end of the second frame 200 away from the first frame 100. When the second platform 2 rotates and folds relative to the first platform 1, the running belt 3 folds accordingly, and when the second platform 2 rotates and unfolds relative to the first platform 1, the running belt 3 unfolds accordingly.
[0039] It is easy to understand that, in order to allow users to experience different running belt speeds or exercise modes, the walking machine also has a control unit on the first frame 100 of the first walking platform 1. The control unit is electrically connected to the drive motor 4 and is used to control the operation of the drive motor 4. The basic structure, operating principle, and working mode of this walking machine are all technical means of relatively mature existing technologies, and will not be explained in detail in this embodiment.
[0040] Further in this embodiment, see Figure 5 and Figure 6 As shown, the top of the first frame 100 of the first walkway 1 is connected to a first plate 102, and the top of the second frame 200 of the second walkway 2 is connected to a second plate 202. Both the first plate 102 and the second plate 202 are plates of uniform thickness, and there is an installation gap between the first plate 102 and the second plate 202. The existence of this installation gap can effectively prevent rotational interference between the second plate 202 and the first plate 102 of the first walkway 1 when the second plate 202 rotates with the second platform, avoid frictional noise, and improve the user experience.
[0041] It is easy to understand that when a user walks or runs on the treadmill belt 3, friction will occur between the treadmill belt 3 and the first plate 102 and the second plate 202, which is particularly likely to cause wear on the back of the treadmill belt 3 or the top of the first plate 102 and the second plate 202; therefore, in this embodiment, see Figure 5 and Figure 6 As shown, the top of the first plate 102 and the second plate 202 are connected to a wear-resistant layer 6 covering the first plate 102 and the second plate 202. In this embodiment, the wear-resistant layer 6 is a flexible friction pad layer made of rubber or plastic. The wear-resistant layer 6 can effectively reduce the wear on the back of the running belt 3 or the top of the first plate 102 and the second plate 202, improve the service life of the running belt 3, and improve the user's walking or running exercise experience.
[0042] It is understandable that, taking a folding treadmill with a width of 50-80 cm and a length of 90-150 cm as an example, the length of its second platform 2 is 40-75 cm. When the second platform 2 rotates and folds relative to the first platform 1, if the rotational clearance of the folding assembly 5 is too large, it will cause the second platform 2 to wobble relative to the first platform 1. Therefore, in this embodiment, see... Figure 5 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, each folding assembly 5 includes an outer main connecting rod 500 and an outer auxiliary connecting rod 501 disposed on the outside of the fixed plate, and an inner main connecting rod 502 and an inner auxiliary connecting rod 503 disposed on the inside of the fixed plate. The outer main connecting rod 500 is hinged to the middle of the inner main connecting rod 502. One end of the outer main connecting rod 500 is hinged to the first fixed plate 101, and the other end of the outer main connecting rod 500 is hinged to the lower end of the outer auxiliary connecting rod 501. The upper end of the outer auxiliary connecting rod 501 is hinged to the second fixed plate 201. One end of the inner main connecting rod 502 is hinged to the second fixed plate 201, and the other end of the inner main connecting rod 502 is hinged to the lower end of the inner auxiliary connecting rod 503. The upper end of the inner auxiliary connecting rod 503 is hinged to the first fixed plate 101.
[0043] In this embodiment, the folding assembly 5 of the folding walking machine is composed of an outer main connecting rod 500, an outer auxiliary connecting rod 501, an inner main connecting rod 502, and an inner auxiliary connecting rod 503. The four connecting rods are respectively hinged to the fixing plates of the first platform 1 and the second platform 2. This not only provides good structural stability but also replaces the sliding connection between the sliding shaft and the strip through groove in related technologies. Therefore, the hinge precision is high, maintaining good fit and levelness of the end faces of the first platform 1 and the second platform 2 after unfolding. It also basically eliminates the shaking phenomenon caused by the gap when the platform body rotates and folds. Therefore, this folding walking machine can eliminate or partially eliminate the shaking during the folding process and has good structural stability, resulting in a better user experience.
[0044] In this embodiment, the hinge is a connection between a pin and a pin hole, and at least one of the two hinged links can rotate relative to the pin. The pin hole is also called a shaft hole, and the pin is also called a hinge pin. This hinged connection between the pin and the pin hole can improve the hinge accuracy, thereby further eliminating the shaking caused by the rotational clearance during the folding process of the platform body.
[0045] For example, see Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the outer auxiliary connecting rod 501 and the inner auxiliary connecting rod 503 are both straight rods, and are respectively located on the outer and inner sides of the fixed plate. The outer main connecting rod 500 and the inner main connecting rod 502 have the same shape, both being arc-shaped or L-shaped, and are respectively located on the outer and inner sides of the fixed plate. Specifically, the outer main connecting rod 500 and the inner main connecting rod 502 each have two rotating arms arranged at a certain angle: a first rotating arm 505 and a second rotating arm 506. The angle between the first rotating arm 505 and the second rotating arm 506 is greater than 90 degrees and less than 150 degrees. In this embodiment, the first rotating arm 505 and the second rotating arm 506 are... The included angle between 6 is preferably 110 degrees; the free end of the first rotating arm 505 of the outer main connecting rod 500 is hinged to the upper part of the first fixed plate 101, and the free end of the second rotating arm 506 of the outer main connecting rod 500 is hinged to the lower end of the outer auxiliary connecting rod 501, and the upper end of the outer auxiliary connecting rod 501 is hinged to the upper part of the second fixed plate 201; the free end of the first rotating arm 505 of the inner main connecting rod 502 is hinged to the upper part of the second fixed plate 201, and the free end of the second rotating arm 506 of the inner main connecting rod 502 is hinged to the lower end of the inner auxiliary connecting rod 503, and the upper end of the inner auxiliary connecting rod 503 is hinged to the upper part of the first fixed plate 101.
[0046] In this embodiment, when the second platform 2 rotates to the unfolded state relative to the first platform 1, the projections of the outer main connecting rod 500 and the inner main connecting rod 502 along the width direction of the platform body are symmetrically arranged about the perpendicular bisector of the line connecting their projections. This arrangement of the folding assembly 5 improves the stability of the first platform 1 and the second platform 2 when folded or unfolded. Further, in this embodiment, see... Figure 10 , Figure 11 , Figure 12 and Figure 13 As shown, the outer main connecting rod 500 and the inner main connecting rod 502 are hinged at the middle by a positioning shaft 504. The lower part of the first fixing plate 101 near the second fixing plate 201 is provided with a C-shaped first positioning groove 103 with an outward opening, and the lower part of the second fixing plate 201 near the first fixing plate 101 is provided with a C-shaped second positioning groove 203 with an outward opening. When the second platform 2 rotates relative to the first platform 1 to the unfolded state, the first positioning groove 103 and the second positioning groove 203 are respectively engaged with the positioning shaft 504. The positioning shaft 504 at the middle of the outer main connecting rod 500 and the inner main connecting rod 502 makes the rotation of the folding assembly 5 more stable and the structure more stable. Moreover, when the second platform 2 is rotated to the fully unfolded state, the first positioning groove 103 on the first fixing plate 101 and the second positioning groove 203 on the second fixing plate 201 are respectively engaged with the positioning shaft 504, thereby realizing the positioning of the first platform 1 and the second platform 2 when unfolded, avoiding the situation of not fully unfolded or over-folded, and improving the convenience of use.
[0047] It is understood that the folding assembly 5 consists of an outer main connecting rod 500, an outer auxiliary connecting rod 501, an inner main connecting rod 502, and an inner auxiliary connecting rod 503. During rotation, the four connecting rods rotate at different amplitudes. To avoid interference between the folding assembly 5 and the rotation of the first frame 100 and the second frame 200, in this embodiment, the first fixing plate 101 protrudes outward from the end of the first platform 1 frame, and the second fixing plate 201 protrudes outward from the end of the second platform 2 frame, creating a rotation gap between the end of the first platform 1 frame and the end of the second platform 2 frame for the folding assembly 5 to rotate. The existence of this rotation gap ensures that when the second platform 2 rotates relative to the first platform 1, it will not interfere with the rotation of the connecting rods of the folding assembly 5, making the folding operation simpler and more convenient.
[0048] It is understandable that when the second platform 2 rotates to a folded state relative to the first platform 1, at least part of the folding assembly 5 faces upwards. To prevent foreign objects from entering the folding assembly 5 and to improve the aesthetics of the treadmill in the folded state, in this embodiment, see... Figure 4As shown, a first cover 104 covering the outside of the first fixed plate 101 is connected to the end of the frame of the first platform 1, and a second cover 204 covering the outside of the second fixed plate 201 is connected to the end of the frame of the second platform 2. The arrangement of the first cover 104 and the second cover 204 can shield and protect the folding assembly 5, providing high safety. In addition, the specific structural arrangement of the folding assembly 5 in this application is also designed so that when the treadmill is in the folded state, at least a part of the structure of the folding assembly 5 can protrude towards the bottom of the first platform 1 and the second platform 2, rather than protruding from the top of the first platform 1 and the second platform 2, thus ensuring the integrity of the top surface of the first platform 1 and the second platform 2 and increasing the aesthetics of the product's surface.
