Technical Field
[0001] This utility model relates to the field of fitness equipment processing and manufacturing technology, and particularly to the field of treadmill processing and manufacturing, and discloses an integrated running board and treadmill. Background Technology
[0002] The traditional treadmill running board is connected to the metal frame separately, which leads to: motor vibration being transmitted to the feet through bolts, resulting in poor comfort; local deformation of the running board causing abnormal noise; and the difference in thermal expansion coefficients between the metal frame and the plastic running board causing connection failure. Utility Model Content
[0003] To solve the above-mentioned technical problems, a one-piece molded running board and treadmill are provided.
[0004] To achieve the above objectives, as a first aspect, the technical solution adopted by this utility model is: an integrally molded running board, comprising,
[0005] The supporting frame is made of engineering plastic and is U-shaped.
[0006] The running board is made of engineering plastic and is injection molded as a single unit with the supporting frame.
[0007] According to this utility model, the running board is further made of 30% carbon fiber reinforced PA6.
[0008] According to this utility model, the support frame is further made of glass fiber reinforced PP.
[0009] According to this utility model, at least two reinforcing ribs are equidistantly arranged at the bottom of the running board along its length direction.
[0010] According to this utility model, the reinforcing rib and the running board are integrally formed.
[0011] According to this utility model, the running board has a thickness of 4-6 cm in the middle and 3 cm at the edge, with the thickness gradually decreasing from the middle to the edge to form a gradient modulus transition.
[0012] According to this utility model, the surface of the running board is further provided with a PU coating.
[0013] According to this utility model, the bottom of the running board is further integrated with a piezoelectric limiting plate with a polarization direction perpendicular to the plane of the running board. The power output terminal is connected to the circuit control module. The control circuit of the circuit control module dynamically adjusts the motor torque based on the piezoelectric signal spectrum analysis of the user's gait characteristics.
[0014] Secondly, this utility model also provides a treadmill that uses the aforementioned one-piece molded running board.
[0015] Compared with the prior art, the advantages of this utility model are as follows: the running board and the support frame are made of engineering plastics, and the running board and the support frame are injection molded into an integrated structure, which reduces production and transportation costs while ensuring structural rigidity.
[0016] By setting a piezoelectric limiter at the bottom of the running board, the piezoelectric fiber generates an electrical charge signal, which is then output to the circuit control module to analyze the gait and automatically control the motor to reduce torque to adapt to the user and ensure user safety.

[0022] 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.
[0023] like Figures 1 to 4 As shown in the illustration, this application discloses an integrally molded running board, including a support frame 100. The support frame is made of engineering plastic, reducing production costs, weight, and transportation costs. The support frame 100 is U-shaped, and the running board 200 is also made of engineering plastic and integrally injection molded with the support frame 100. Preferably, the running board 200 is made of 30% carbon fiber reinforced PA6, which can withstand the impact of being stepped on and prevent the running board 200 from breaking. The support frame 100 is made of glass fiber reinforced PP, which has high tensile strength and can bear a high load, and low creep, avoiding deformation problems after long-term use. Moreover, glass fiber reinforced PP has a low density, achieving overall lightweighting and further reducing transportation costs. Both the running board 200 and the support frame 100 are made of engineering plastic, solving the problem of thermal stress deformation at the connection between the metal frame and the running board in the prior art.
[0024] Furthermore, reinforcing ribs 210 are provided at the bottom of the running board 200 to further improve the load-bearing capacity of the running board 200; multiple reinforcing ribs 210 are arranged along the length of the running board 210 to ensure that the stress is evenly distributed in all parts of the running board 200. Preferably, the reinforcing ribs 210 and the running board 200 are integrally formed.
[0025] In this embodiment of the application, the thickness of the running board 200 in the middle is 4-6cm and the thickness at the edge is 3cm. The thickness gradually decreases from the middle to the edge, forming a gradient modulus transition.
[0026] In this embodiment of the application, a PU coating 500 is provided on the surface of the running board 200 to improve the anti-slip performance of the running board 200.
[0027] In this embodiment, a piezoelectric limiting plate 300 is integrated at the bottom of the running board 200, with the polarization direction perpendicular to the plane of the running board 200. The power output terminal is connected to the circuit control module 400. The control circuit of the circuit control module 400 dynamically adjusts the motor torque based on the piezoelectric signal spectrum analysis of the user's gait characteristics.
[0028] When a user steps on the device and experiences an impact, the piezoelectric fibers of the piezoelectric limiter 300 generate an electrical charge signal, which is then output to the circuit control module 400. The circuit control module 400 is specifically an FTT analysis module, used to transmit voltage waveforms and analyze gait, extracting the main frequency and harmonics. When the main frequency is greater than a set threshold, it is determined to be an elderly person, and the motor is automatically controlled to reduce torque to accommodate the user and ensure user safety.
[0029] 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.
