Description

Technical Field

[0001] The utility model relates to the field of switch signal testing equipment, and more particularly to a new flywheel structure of a rowing machine. Background Art

[0002] Rowing machines, a fitness device that simulates the motion of rowing, are widely popular among users for their full-body muscle training. The core component of a rowing machine is the flywheel, which generates resistance by rotating and cutting the magnetic field of the magnetron group. When the user pulls the paddle, they need to overcome the resistance generated by the flywheel, achieving the desired exercise effect.

[0003] Existing rowing machines generally use cast iron flywheels, which have a large weight and inertia. This structure can provide relatively stable resistance to a certain extent, but it also has the following problems:

[0004] (1) Weight issue: The heavy weight of cast iron flywheels directly increases transportation costs. Especially in the context of the rapid development of e-commerce, express delivery costs are closely related to product weight. Cast iron flywheels significantly increase product logistics costs.

[0005] (2) High manufacturing cost: Cast iron materials are complex to process, and the energy consumption during the manufacturing process is high, which leads to increased production costs.

[0006] (3) Inertia problem: Rowing machines require stable resistance rather than the inertia of a flywheel, but the high inertia of a cast iron flywheel may affect the user experience and weaken the exercise effect.

[0007] (4) Innovation needs: The market has a strong demand for lightweight, low-cost and stable performance rowing machine flywheels, and existing technologies cannot meet these needs at the same time.

[0008] Therefore, there is an urgent need for a rowing machine flywheel structure that can maintain resistance performance while reducing weight and lowering costs. Utility Model Content

[0009] In order to solve the above problems, the utility model provides a new flywheel structure for a rowing machine. Through the improved structural design, the device has good portability, reset stability and applicability.

[0010] To achieve the above objectives, the present invention provides the following technical solutions, which mainly include:

[0011] A new rowing machine flywheel structure, comprising:

[0012] A flywheel body, wherein a pulley is provided at the central axis of the flywheel body, and the flywheel body is welded by a steel pipe and an iron plate, or is made of nylon material;

[0013] An outer aluminum ring is fixed to the outer periphery of the flywheel body by screws;

[0014] The magnetic control group is arranged outside the flywheel body and generates resistance by rotating the flywheel body to cut the magnetic field.

[0015] Preferably, the flywheel body is formed into a circular structure by welding a steel pipe and an iron plate, and the overall strength and stability of the flywheel body are enhanced by rationally distributing welding points.

[0016] Preferably, the flywheel body is integrally injection-molded from nylon material to further reduce the weight of the flywheel body and improve corrosion resistance.

[0017] Preferably, the outer aluminum ring is made of pure aluminum material, and its outer surface is anodized to improve wear resistance and corrosion resistance.

[0018] Preferably, the screw is fixed to the flywheel body through a thread and is equipped with an anti-loosening washer to ensure the fixation reliability of the outer aluminum ring under high-speed rotation.

[0019] Preferably, the gap of the magnetic control group is adjustable within a range of 1 mm to 10 mm, so as to achieve flexible adjustment of the resistance of the rowing machine and meet the exercise needs of different users.

[0020] It can be seen from the above technical solutions that, compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) Significant weight reduction: By replacing the traditional cast iron flywheel with a flywheel body made of welded steel pipe and iron plate or nylon injection molding, the overall weight of the flywheel is greatly reduced. Compared with the traditional design, the weight can be reduced by more than 50%, which not only facilitates the transportation and installation of the equipment, but also improves the market competitiveness of the product.

[0022] (2) Significant cost reduction: Optimized material selection effectively reduces manufacturing costs. Steel pipes, iron plates, and nylon are more readily available and less expensive to process than cast iron, while also reducing the complexity of the flywheel production process. The reduced weight significantly reduces logistics and delivery costs, especially in e-commerce sales models, solving the transportation cost problem of heavy products.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a lightweight flywheel structure formed by welding a steel pipe and an iron plate, specifically as follows:

[0032] Structure and materials of flywheel body 1:

[0033] The flywheel body 1 is welded together from high-strength steel pipes and high-quality iron plates. The steel pipes serve as the flywheel's outer frame, providing sufficient structural strength and rigidity; the iron plates, the flywheel's core, ensure its balance and resistance to deformation.

[0034] The pulley 4 and the flywheel body 1 are of a split structure. The pulley 4 is mounted on the flywheel body 1 by screws 5. The pulley 4 is made of nylon to ensure overall lightweight.

[0035] The welding adopts precise automatic equipment to ensure the uniform distribution and firmness of the welding points, effectively avoiding the deformation or failure of the flywheel due to stress concentration.

[0036] The surface of steel pipes and iron plates is treated with anti-rust treatment (such as electroplating or spraying) to further improve their corrosion resistance and extend their service life.

[0037] Design and fixing method of the outer aluminum ring 2:

[0038] A circle of outer aluminum ring 2 is fixed to the outer periphery of the flywheel body 1. The aluminum ring 2 is made of pure aluminum material, which has the characteristics of lightness and high conductivity, helping to enhance the magnetic field cutting effect, thereby providing stable resistance performance.

[0039] The aluminum ring 2 is firmly connected to the flywheel body 1 by multiple screws. The screws are equipped with anti-loosening washers to ensure that the aluminum ring 2 does not loosen or deviate when the flywheel rotates at high speed.

[0040] The surface of the aluminum wheel 2 is anodized to improve wear resistance and corrosion resistance, and can maintain good appearance and function even under long-term and high-intensity use.

[0041] Coordination and resistance adjustment of magnetic control group 3:

[0042] The magnetron group 3 is installed on the outside of the flywheel body 1 and forms a working cooperation with the outer aluminum ring 2. When the flywheel body 1 rotates, the aluminum ring 2 cuts the magnetic field of the magnetron group 3, generating a stable resistance.

[0043] The gap between the magnetic control group 3 and the flywheel body 1 can be adjusted manually by the adjustment mechanism, with an adjustment range of 1mm to 10mm. Users can freely choose the resistance level according to their personal exercise intensity requirements.

[0044] The magnetron group 3 adopts a modular design, which is convenient for users to maintain, replace or upgrade in the future.

[0045] Lightweight and balanced optimization:

[0046] Compared to traditional cast iron flywheels, the flywheel body 1 is approximately 50% lighter. This lightweight design not only reduces transportation costs but also makes the overall structure of the rowing machine easier to install and maintain.

[0047] The flywheel body 1 is designed with dynamic balancing correction to ensure that it runs smoothly at high speed without obvious vibration or noise, thereby improving the user experience.

[0048] Verification of resistance performance:

[0049] After testing, it was found that the resistance provided by the lightweight flywheel structure of this embodiment during use is comparable to that of a traditional cast iron flywheel, and in high resistance mode, the resistance curve is smoother and the user experience is better.

[0050] Application scenarios and applicability:

[0051] This embodiment is particularly suitable for home fitness equipment and e-commerce sales models that have high requirements for equipment weight and transportation costs. At the same time, due to the low material and processing costs, the flywheel structure can also be widely used in gyms or commercial rowing machines.

[0052] Through the specific implementation of this embodiment, the steel pipe and iron plate welded flywheel structure achieves weight reduction, cost reduction and performance optimization, providing an economical and efficient technical solution for the rowing machine.

[0053] Example 2

[0054] like Figure 3 and Figure 4 As shown, this embodiment provides a lightweight flywheel structure that is integrally injection molded using nylon material, and the specific contents are as follows:

[0055] Design and materials of flywheel body 1:

[0056] The flywheel body 1 is injection molded from high-strength engineering nylon. Nylon is lightweight, tough, wear-resistant, and corrosion-resistant. Compared to traditional cast iron, it reduces weight by approximately 60%, fundamentally achieving a lightweight flywheel design.

[0057] The flywheel body 1 is designed as an integrated structure, which avoids stress concentration problems that may occur during welding or assembly, and ensures the overall strength and balance of the flywheel.

[0058] In order to further improve the material properties, a certain proportion of glass fiber (such as 15% to 30%) is added to nylon to enhance the impact resistance and rigidity of the flywheel and extend its service life.

[0059] Fixation and function enhancement of the outer aluminum ring 2:

[0060] The flywheel body 1 is surrounded by an outer aluminum ring 2, which is connected to the flywheel body 1 through a reserved embedded screw hole. The fixing method of the aluminum ring 2 combines the dual design of mechanical locking and thread fixing to ensure its stability during high-speed rotation.

[0061] The aluminum wheel 2 is made of pure aluminum and is anodized. It has excellent corrosion resistance and electrical conductivity, and can efficiently cut the magnetic field of the magnetron group 3, thereby providing resistance performance comparable to that of a traditional flywheel.

[0062] Working principle and adjustment of magnetron group 3

[0063] The magnetron group 3 is mounted outside the flywheel body 1. As the flywheel rotates, the aluminum ring 2 cuts through the magnetic field of the magnetron group 3, generating resistance. The amount of resistance can be controlled by adjusting the gap between the flywheel body 1 and the magnetron group 3, with an adjustment range of 1mm to 10mm.

[0064] This design meets the personalized needs of different users for exercise intensity and ensures the safety and reliability of the equipment during resistance adjustment.

[0065] Lightweight and efficient transmission:

[0066] Due to the lightweight properties of the nylon material itself, the weight of the flywheel body 1 is significantly reduced compared to a traditional cast iron flywheel, making the rowing machine lighter overall and easier to carry and install.

[0067] The flywheel body 1 adopts an optimized shape design to reduce air resistance and transmission loss, thereby improving movement efficiency and providing users with a smoother usage experience.

[0068] Resistance performance and user experience:

[0069] After actual testing, the nylon flywheel structure can provide stable and continuous resistance output in different resistance modes, especially in low resistance mode, which is very suitable for beginners or rehabilitation training needs.

[0070] Due to the high toughness and good dynamic balance of the flywheel body 1, vibration and noise are significantly reduced during equipment operation, and the user experience is greatly improved.

[0071] Durability and environmental protection features:

[0072] Nylon material has excellent weather resistance and can resist humidity, temperature changes and chemical corrosion, and will not significantly age or damage even after long-term use.

[0073] Compared with traditional cast iron materials, the production process of nylon flywheels is more environmentally friendly, reduces energy consumption and carbon emissions, and is in line with the concepts of green manufacturing and sustainable development.

[0074] Application scenarios and market advantages:

[0075] This embodiment is particularly suitable for home fitness scenarios that require high portability and user-friendliness. In addition, due to the weight advantage of the nylon flywheel, it is suitable for e-commerce sales channels and can significantly reduce express delivery costs.

[0076] In the field of rehabilitation medicine, nylon flywheels also have broad application potential due to their stability and lightweight properties.

[0077] Through the specific implementation of this embodiment, the flywheel body (1) made of nylon material successfully achieves the goals of reducing weight, reducing costs and enhancing durability, while maintaining excellent resistance performance and user experience. This design provides an ideal solution for the modernization and multi-scenario application of rowing machines.
