Detailed Implementation

[0024] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0025] like Figures 1 to 6 As shown in the figure, this application discloses a dual-motor roller treadmill, including a frame 100. The frame 100 includes a horizontal base 110 and an adjustable tilt support component 120 connected thereto. One end of the support component 120 is connected to the running board 310 described in detail below. The support component 120 can adjust the angle between the running board 310 and the horizontal bottom surface by telescopic adjustment, thereby changing the tilt angle of the running board 310 and changing the exercise intensity of the exerciser. Two integrated direct-drive electric rollers 200 are respectively connected to the front end and rear end of the horizontal base 110, and the two ends of their roller shafts 210 are fixed to the side plates of the horizontal base 110. It also includes a running platform assembly 300, which includes the running board 310 and a running belt 320 disposed thereon. The running belt 320 is an anti-static running belt, which wraps the direct-drive electric rollers 200 in an Ω-shaped single-layer winding manner, with a wrap angle range of 280°-310°. The driver of the direct-drive electric roller 200 is connected to an external control console (not shown) via a cable to drive the direct-drive electric roller 200.

[0026] It adopts two dual direct-drive electric rollers 200, which are dual roller drives.

[0027] It includes a main roller and an auxiliary roller. The main roller bears 80% of the driving torque. The power distribution ratio between the main roller and the auxiliary roller is 4:1, and the auxiliary roller is only activated during braking.

[0028] The direct-drive electric roller servo motor, model DGDD50 / 67-100, comprises a roller housing, roller shaft, signal lines, a permanent magnet brushless DC motor, and an inductive encoder. The inductive encoder consists of a rotating module and a stator module. The rotating module rotates with the roller housing and interacts with the stator module to receive signals. These signals are then processed by a chip to obtain a high-precision position signal, which is transmitted to the motor control system. This allows for precise control of the permanent magnet brushless DC motor's start / stop, speed control, and power density monitoring. This direct-drive electric roller servo motor boasts advantages such as compact structure, light weight, high position accuracy, and high torque. Furthermore, due to the non-contact sensing principle of the inductive position encoder, it is suitable for operation in various harsh environments, including humid, muddy, and dusty conditions.

[0029] In this embodiment, a heat dissipation structure is also included, integrated on the frame 100, with a position corresponding to the direct-drive electric roller 200. The heat dissipation structure includes a housing 400 with multiple microchannels, and a phase change material filling layer with a melting point of 45±2℃ is disposed inside it. Preferably, the phase change material is a paraffin or expanded graphite composite material, which absorbs or releases latent heat through a phase change process to achieve temperature regulation and energy management, and maintain a good heat dissipation effect.

[0030] In this embodiment, the support component 120 is an electrically adjustable telescopic rod. By adjusting the telescopic length of the rod, the tilt angle of the running board 310 is changed. Furthermore, the telescopic rod includes a first connecting part and a second connecting part connected by threads, which improves the adjustment accuracy of the running board's tilt angle.

[0031] In this embodiment, the running board 310 has a multi-layer composite structure, consisting of a glass fiber reinforced polyurethane layer 311, a honeycomb aluminum core 312, and a damping rubber layer 313 from top to bottom. The glass fiber reinforced polyurethane layer 311 has a thickness of 3±0.2mm, the honeycomb aluminum core 312 has a pore size of Φ5mm, and the damping rubber layer 313 has a loss factor ≥0.3. This design improves the running board's lifespan while enhancing its shock absorption effect, reducing vibration, and increasing exercise comfort.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
