Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a running structure with dual motors for storage. Background Technology

[0002] The running structure, a type of fitness equipment, refers to the mechanical structure or frame system at the bottom of a treadmill that supports the running belt. The running structure uses a motor and rollers to rotate the running belt, allowing users to run on it for indoor aerobic exercise. The running structure includes a bottom supporting frame, inside which a running board is installed. The running board supports the rotating running belt, preventing it from collapsing. A foldable running structure refers to a treadmill bottom frame that can be folded up to save space when not in use. During folding, a drive component moves the frame, simultaneously retracting the running board and running belt.

[0003] Existing retractable running structures, when used, rely on a drive component on one side of the running frame to retract it. This can easily lead to biased torques during retraction and unfolding, causing the running frame to tilt and become unstable, increasing the risk of the running belt deviating from its intended path. Utility Model Content

[0004] The purpose of this invention is to provide a dual-motor retractable running structure, which has the advantage of stable unfolding and folding. It solves the problem that in the existing retractable running structures, the running frame is easily affected by bias torque during unfolding and folding due to the driving component set on one side of the running frame, which causes the running frame to tilt and become unstable, increasing the risk of the running belt running off-center.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a running structure with dual motors for storage, including a first running frame and a second running frame, wherein the second running frame is located on one side of the first running frame and is movably connected to it, and running belts are installed on the first and second running frames;

[0006] The surfaces of the first and second running frames are rotatably connected by a first connecting rod and a second connecting rod. Inside the first running frame, two parallel first motors are installed, and the output shaft of the first motor is connected to one end of the first connecting rod.

[0007] The first running frame is equipped with a first position detection switch and a second position detection switch. The first position detection switch is located in the deployed position of the first link to detect the deployed state of the first link, and the second position detection switch is located in the retracted position of the first link to detect the retracted state of the first link.

[0008] As a preferred embodiment of the dual-motor storage running structure of this utility model, a first running board is installed inside the first running frame, and a second running board that works in conjunction with the first running board is installed inside the second running frame.

[0009] As a preferred embodiment of the dual-motor storage running structure of this utility model, the tops of the first running board and the second running board are movably connected to the inner wall of the running belt.

[0010] As a preferred embodiment of the dual-motor storage running structure of this utility model, the first running frame is provided with a first support frame inside, and the first support frame is installed at the bottom of the first running board.

[0011] As a preferred embodiment of the dual-motor storage running structure of this utility model, a second support frame is installed inside the second running frame, and the second support frame is installed at the bottom of the second running board.

[0012] As a preferred embodiment of the dual-motor storage running structure of this utility model, the first running frame is rotatably connected to an active roller, and the second running frame is rotatably connected to a driven roller. The active roller and the driven roller are located on the left and right sides inside the running belt and are movably connected to it.

[0013] As a preferred embodiment of the dual-motor storage running structure of this utility model, a second motor is fixedly installed inside the first running frame, and the output shaft of the second motor is connected to the drive roller through a transmission assembly.

[0014] As a preferred embodiment of the dual-motor storage running structure of this utility model, the first running frame and the bottom of the second running frame are fixedly installed with support legs.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model significantly improves the stability, synchronization, and safety of the retractable running structure during unfolding and retraction by adopting a symmetrical linkage mechanism with parallel dual motors for retraction. The two first motors are installed in parallel inside the first running frame, synchronously driving the first linkage, and working with the second linkage to form a stable linkage motion system. This ensures that the second running frame is evenly stressed and moves smoothly during rotation, effectively avoiding the problems of tilting, twisting, or shaking that are easily caused by traditional single-sided drive. At the same time, the first and second position detection switches accurately monitor the position of the first linkage, realizing automatic start and stop control, ensuring that the structure is reliably locked when fully unfolded or fully retracted, improving the intelligence and safety of operation. In addition, the dual motors work together to provide sufficient driving torque, ensuring smooth and efficient retraction even under long-term use or heavy load, greatly reducing mechanical wear and extending the service life of the entire machine.

[0017] 2. This utility model forms a continuous and flat running support surface by splicing the first running board and the second running board. The running belt runs smoothly on it, and the active roller driven by the second motor drives the driven roller to achieve cyclic operation. Together with the first support frame and the second support frame, it provides stable support, ensuring running comfort and structural rigidity. During the storage process, the second running frame drives the second running board and the driven roller to fold upward, so that the running belt naturally folds into a "Z" shape. The second running board is stacked on top of the first running board. The overall structure is compact and significantly reduces the floor space occupied, making it particularly suitable for home environments with limited space. The support legs provide reliable support in the unfolded state to ensure operational safety. In summary, this solution takes into account both high-performance running experience and convenient storage function, and achieves an organic unity of structural stability, space utilization and user experience.

[0024] Please see Figures 1-5 A dual-motor storage running structure includes a first running frame 1 and a second running frame 2. The second running frame 2 is located on one side of the first running frame 1 and is movably connected to it. Running belts 10 are installed on the first running frame 1 and the second running frame 2.

[0025] Furthermore, the surfaces of the first running frame 1 and the second running frame 2 are rotatably connected by a first connecting rod 3 and a second connecting rod 4. The first running frame 1 has two parallel first motors 7 installed inside, and the output shaft of the first motor 7 is connected to one end of the first connecting rod 3.

[0026] Furthermore, a first position detection switch 5 and a second position detection switch 6 are installed on the surface of the first running frame 1. The first position detection switch 5 is located in the unfolded position of the first connecting rod 3 to detect the unfolded state of the first connecting rod 3, and the second position detection switch 6 is located in the retracted position of the first connecting rod 3 to detect the retracted state of the first connecting rod 3.

[0027] Furthermore, the first running frame 1 is equipped with a first running plate 8, and the second running frame 2 is equipped with a second running plate 9 that works in conjunction with the first running plate 8.

[0028] Furthermore, the tops of the first running board 8 and the second running board 9 are movably connected to the inner wall of the running belt 10.

[0029] Furthermore, the first running frame 1 is provided with a first support frame 14 inside, and the first support frame 14 is installed at the bottom of the first running plate 8.

[0030] Furthermore, a second support frame 15 is installed inside the second running frame 2, and the second support frame 15 is installed at the bottom of the second running plate 9.

[0031] Furthermore, the first running frame 1 is rotatably connected to the drive roller 11, and the second running frame 2 is rotatably connected to the driven roller 13. The drive roller 11 and the driven roller 13 are located on the left and right sides inside the running belt 10 and are movably connected to it.

[0032] Furthermore, a second motor 12 is fixedly installed inside the first running frame 1, and the output shaft of the second motor 12 is connected to the drive roller 11 through a transmission assembly.

[0033] Furthermore, the first running frame 1 and the second running frame 2 are fixedly installed with support legs 16 at their bottoms.

[0034] When the user activates the storage or unfolding function, the two first motors 7 installed inside the first running frame 1 operate synchronously. Their output shafts drive the first connecting rod 3 connected to them to rotate. Since the first running frame 1 and the second running frame 2 form a movable hinged linkage mechanism on both sides through the first connecting rod 3 and the second connecting rod 4, the rotational movement of the first connecting rod 3 will drive the second running frame 2 to rotate relative to the first running frame 1 around the connection point, thereby realizing the smooth transition of the whole machine from the unfolded state to the storage state, or from the storage state to the horizontal use state. When the second running frame 2 rotates, it synchronously drives the second connecting rod 4 to rotate. The second connecting rod 4 provides auxiliary support for the second running frame 2 to prevent the second running frame 2 from shaking during the storage process.

[0035] The dual-motor storage design significantly improves the synchronization, stability, and safety of the retractable running frame during unfolding and folding. Since the two first motors 7 drive the first connecting rods 3 located on opposite sides of the surface, a symmetrical and balanced power output is achieved. This effectively avoids the problems of frame twisting, tilting, or uneven force distribution caused by traditional single-sided drive, ensuring that the second running frame 2 remains parallel to the first running frame 1 during movement and rotates smoothly around the hinge point. This symmetrical drive method not only significantly reduces local stress concentration in the connecting rod structure and extends the overall lifespan of the machine, but also reduces shaking, abnormal noise, and jamming during operation, improving the user's sense of smoothness and safety. Simultaneously, the coordinated work of the two motors provides more sufficient driving torque, ensuring reliable and efficient folding performance.

[0036] Moreover, the dual-motor storage design can solve the defect of placing the storage motor in the middle of the running structure. When the storage motor is placed in the middle, it will cause the middle position to bulge, and corresponding support rollers need to be set to avoid friction in the middle position of the running belt. In this invention, the first motor 7 is stored in the inner wall of the first running frame 1, without occupying the position of the first running plate 8 and the second running plate 9, thus improving the integration of the equipment.

[0037] During the storage and unfolding process, the first position detection switch 5 and the second position detection switch 6 located on both sides of the surface of the first running frame 1 monitor the position of the first connecting rod 3 in real time. When the first connecting rod 3 reaches the fully unfolded position, the first position detection switch 5 is triggered, and the system controls the first motor 7 to stop running, ensuring that the running structure is stable and in use. When the first connecting rod 3 moves to the storage limit position, the second position detection switch 6 is triggered, and the first motor 7 is immediately de-energized, completing the storage and positioning.

[0038] During the storage process, the second running frame 2 and the driven roller 13 simultaneously fold the running belt 10 into a "Z" shape. The second running frame 2 then moves the second running plate 9 to the top of the first running frame 1 and the first running plate 8. The second running plate 9 is stacked on the first running plate 8, reducing the footprint of the running structure.

[0039] In running mode, the second motor 12 inside the first running frame 1 drives the active roller 11 to rotate through the transmission assembly, causing the running belt 10, which surrounds the active roller 11 and the driven roller 13, to run in a cycle. The inner wall of the running belt 10 slides in contact with the top surfaces of the first running plate 8 and the second running plate 9, providing support and cushioning. The first running plate 8 is supported at the bottom of the first running frame 1 by the first support frame 14, and the second running plate 9 is supported at the bottom of the second running frame 2 by the second support frame 15, together forming a continuous and flat running platform. The entire structure is stably supported by the support legs 16 fixedly installed at the bottom of the first running frame 1 and the second running frame 2 in the unfolded state, ensuring safe and reliable operation.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
