Description

Technical Field

[0001] This utility model belongs to the technical field of cycling trainer brackets, and particularly relates to an integrated body of a cycling trainer bracket. Background Technology

[0002] Existing cycling trainer brackets typically employ a multi-part, modular design. The main body is often assembled and welded from numerous iron plates, resulting in an irregular and imprecise shape. Its mounting references are scattered and lack a unified, high-precision positioning structure. The flywheel is mounted on a cantilever shaft on the outside of the main body, occupying a large volume and exhibiting poor overall stability. Furthermore, the structure between the main body, front support, and bottom support tube is often a fixed, welded, integrated design, and the bottom front support tube is usually very long, leading to large packaging volume and high transportation and storage costs. Simultaneously, this makes it difficult for users to replicate the original relative positions of core components, especially the electromagnetic backpack and flywheel assembly, after disassembly and reassembly. This can easily lead to cumulative installation errors, causing changes or interference in critical working clearances, resulting in decreased product performance, abnormal noises, or wear. Recalibration often requires specialized tools and techniques, resulting in a poor user experience. This fails to ensure that users can easily and accurately restore the product to its factory condition after disassembly and reassembly, and cannot overcome the performance degradation problem after disassembly and reassembly of traditional products, nor guarantee the accuracy of electromagnetic resistance and power detection. Utility Model Content

[0003] The purpose of this utility model is to provide a cycling trainer bracket with a regular and precise main body shape and an integrated main body and assembly structure, which can greatly reduce the packaging volume, significantly reduce transportation and storage costs, improve the overall stability of the cycling trainer bracket, and ensure that users can easily and accurately restore the product to its factory state after disassembling the cycling trainer assembled from this integrated main body. All core components are automatically positioned by the precision installation benchmark on the main body, and can be accurately reproduced without professional adjustment. Moreover, the integrated main body of the cycling trainer bracket overcomes the problem of performance degradation after disassembly and assembly of traditional products.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0032] like Figures 1-11As shown, an integrated body of a cycling trainer bracket includes a main body 1, which is integrally made of a rectangular tube. The main body 1 has an electromagnetic backpack mounting opening 10, a flywheel mounting opening 11, a flywheel clearance opening 31, and bushing mounting holes 15, and a bushing 2 is fixedly mounted thereon. The two side plates of the flywheel mounting opening 11 have corresponding semi-circular flange fixing openings 11-1, and several flywheel mounting holes 30 are provided along the edges of the semi-circular flange fixing openings 11-1. The main body 1 positions and mounts a flywheel assembly 22 through the flywheel mounting holes 30. The flywheel clearance opening 31... 1. It is opened on the other side of the main body 1, corresponding to the semi-circular flange fixing port 11-1; the electromagnetic backpack mounting notch 10 is located on the opposite side of the flywheel mounting port 11 and adjacent to the flywheel clearance port 31. Several electromagnetic backpack mounting holes 10-1 are provided on the edge of the electromagnetic backpack mounting notch 10, and an electromagnetic backpack 21 is positioned and installed at the electromagnetic backpack mounting notch 10, so that a predetermined gap 23 between the electromagnetic backpack 21 and the flywheel assembly 22 is formed between the backpack and the flywheel; the flywheel assembly 22 and the electromagnetic backpack 21 form an electromagnetic resistance device.

[0033] This utility model features a main body 1 made of a single rectangular tube with a fixed bushing 2, eliminating the need for splicing and welding multiple plates. The main body 1 has an electromagnetic backpack mounting notch 10, a flywheel mounting port 11, and bushing mounting holes 15, with the bushing 2 fixedly mounted. The electromagnetic backpack 21 and flywheel assembly 22 are integrated into a single unit. Therefore, before product disassembly and transportation, the integrated main body does not need to be disassembled and packaged, reducing the number of parts and disassembly / assembly steps, and lowering the overall structural complexity. Furthermore, the two side plates of the flywheel mounting port 11 on one side of the main body 1 have multiple flywheel mounting holes 30 at the edge of the semi-circular flange fixing port 11-1 for precise positioning of the flywheel assembly 22. Simultaneously, a flywheel clearance opening 31 is provided on the other side of the main body 1, effectively preventing motion interference. Since the electromagnetic backpack mounting notch 10 is located on the opposite side of the flywheel mounting port 11 and adjacent to the flywheel clearance port 31, the electromagnetic backpack mounting hole 10-1 on it is used to fix the electromagnetic backpack 21. Through structural design, a stable backpack and flywheel predetermined gap 23 is formed between the electromagnetic backpack 21 and the flywheel assembly 22. Therefore, the gap control of the flywheel predetermined gap 23 ensures the operating accuracy and reliability of the electromagnetic resistance device, reduces production costs and assembly errors, and ensures that the parts themselves and their various functional areas have extremely high consistency and accuracy. Furthermore, the flywheel mounting port 11 on it provides a unique and repeatable positioning reference for the flywheel assembly 22 through several flywheel mounting holes 30 with precise positions. Similarly, the several electromagnetic backpack mounting holes set at the edge of the electromagnetic backpack mounting notch 10 provide precise positioning for the electromagnetic backpack 21, ensuring that the downstream components can return to the unique and correct position each time they are assembled. Thus, through the precision machining of the main body 1, the predetermined gap 23 between the electromagnetic backpack 21 and the flywheel assembly 22 remains unchanged after each reassembly, ensuring the performance stability and reliability of the electromagnetic resistance device. This completely avoids problems such as loss of precision, friction, or abnormal noise caused by repeated disassembly and assembly, and significantly improves the maintainability and service life of the product.

[0034] like Figure 2 , 4 As shown in Figures 9 and 1, the main body 1 also has a circuit board mounting hole 12, a circuit board fixing hole 13, and a sensor sensing hole 14. The sensor sensing hole 14 is provided on the side of the flywheel assembly 22 and is located on the detection channel of the sensor mounted on the circuit board mounting hole 12 and the circuit board fixing hole 13.

[0035] The precise structural positioning achieves accurate, stable, and easily repeatable assembly of the detection system. The circuit board mounting holes 12 and fixing holes 13 on the main body 1 provide a direct and unique mounting reference for the circuit board, ensuring the high consistency of the circuit board and its sensors' installation positions each time. The sensor sensing holes 14 are positioned corresponding to the side of the flywheel assembly 22 and precisely located on the detection channel of the installed sensor, allowing the sensor to directly and unobstructedly perform non-contact detection of the flywheel assembly 22's operating status through the sensing holes 14. This integrated design fundamentally avoids problems such as sensor bracket displacement and changes in the relative position of the detection target caused by repeated disassembly and vibration in traditional methods, ensuring the accuracy and consistency of the detection signal. This significantly improves the control accuracy of the electromagnetic resistance device and the overall product reliability. Simultaneously, it further reduces the number of independent sensor bracket parts and subsequent cumbersome calibration steps, simplifying the overall assembly process. Users can automatically restore factory-grade detection accuracy without professional tools or techniques during disassembly and reassembly, resulting in a significant improvement in maintainability and user experience.

[0036] like Figure 1 , 2 As shown in Figures 3, 4, and 9, an electromagnetic backpack mounting hole 10-1 is provided at the edge of the electromagnetic backpack mounting notch 10. The electromagnetic backpack mounting hole 10-1, which is used for precise positioning, is located on the protruding part of the electromagnetic backpack mounting notch 10 of the main body 1 near the flywheel clearance opening 31.

[0037] By placing the electromagnetic backpack mounting hole 10-1 for precise positioning on a special protruding part of the main body 1 near the flywheel clearance opening 31, the installation stability and positioning uniqueness of the electromagnetic backpack 21 are ensured. The electromagnetic backpack mounting hole 10-1 for precise positioning is located in the electromagnetic backpack mounting notch 10 and near the flywheel clearance opening 31. This position makes full use of the structural space of the main body 1. The special protruding structure and the special hole position work together with the other electromagnetic backpack mounting holes 10-1 on the electromagnetic backpack mounting notch 10 to form an asymmetrical positioning system, which can effectively prevent the electromagnetic backpack 21 from being misaligned during assembly and ensure that the orientation of each installation is absolutely correct. Meanwhile, the electromagnetic backpack mounting hole 10-1 for precise positioning serves as an additional fixing point, significantly enhancing the rigid connection of the electromagnetic backpack 21 on the side near the flywheel clearance opening 31. This effectively suppresses the slight displacement or vibration that may occur during long-term operation of the electromagnetic backpack 21, thereby maintaining the stability of the crucial backpack and flywheel predetermined gap 23 between the electromagnetic backpack 21 and the flywheel assembly 22 for a long time. This further ensures the transmission accuracy and performance reliability of the electromagnetic resistance device, improving the overall durability of the product and the user experience.

[0038] like Figure 2 , 4 As shown in Figures 9 and 1, the main body 1 also has a wire binding hole 18, a wire clamping plate mounting hole 19, and a power cord hole 20.

[0039] By incorporating cable binding holes 18, wire clamp mounting holes 19, and power cord holes 20, a unique and unified layout scheme is provided for the fixing, routing, and external access of all cables inside the equipment. Cable binding holes 18 are used to directly fix and guide the cable bundle, wire clamp mounting holes 19 are used to install wire clamps to centrally and tightly fix the cables, and power cord holes 20 provide a standardized path for the introduction of external power cords. This avoids the problems of increased parts, cumbersome assembly steps, and inconsistent positions caused by the need to install independent wire clamps or cable ties in traditional designs. It ensures that all cables can be managed neatly and reliably, effectively preventing cables from falling off, wearing down, or interfering with internal moving parts due to vibration during equipment operation. This greatly improves the safety and reliability of the product. At the same time, it allows users to easily restore the cable layout to its optimal state after disassembly and reassembly, making the maintenance process simple and intuitive, further strengthening the product's core advantage of ease of maintenance.

[0040] like Figure 1 , 2 As shown in Figures 3, 4, and 9, the top of the main body 1 is provided with a front support mounting notch 33, and the bottom of the main body 1 is provided with a bottom support tube welding notch 29.

[0041] The front support mounting notch 33 at the top of the main body 1 facilitates the welding of the front support 3 to the main body 1, increases the welding surface of the front support 3, and makes the welding more robust; the machining of the front support clearance notch 33 makes the clearance recess of the bicycle frame larger, which facilitates the installation of the bicycle frame.

[0042] The bottom support tube welding notch 29 set at the bottom of the main body 1 can be directly welded to the bottom support tube to form a rigid connection node, thereby improving the main structure's ability to resist lateral torsion. The modular welding and connection method, while ensuring the overall structural strength, also facilitates production and transportation, which is an important optimization of the product's core performance and manufacturability.

[0043] like Figure 1 , 2 As shown in Figures 3, 4, and 9, the main body 1 is also provided with a bicycle frame clearance notch 26 and a shell clearance notch 27.

[0044] The bicycle frame clearance notch 26 on the main body 1 provides dedicated space for bicycle rear forks of different sizes, effectively avoiding motion interference between the frame and the main structure, and improving the product's compatibility with various models. The shell clearance notch 27 provides precise clearance space for the installation of the main body's external covering, ensuring that the shell can fit tightly to the main body's contour, thus creating a clean and beautiful overall appearance.

[0045] like Figure 2 , 4 As shown in Figures 9 and 1, the main body 1 also has several outer shell clearance mounting holes 25.

[0046] The housing is directly mounted by a number of housing clearance mounting holes 25 set on the main body 1. The integrated design eliminates the need for additional adapter brackets, which not only simplifies the assembly process, but also ensures the consistency and firmness of the housing installation position, effectively preventing vibration and abnormal noise.

[0047] like Figure 1 , 3 As shown, the main body 1 also has a tensioning wheel adjusting and fixing block welding port 28.

[0048] The welding port 28 of the tensioner adjustment fixing block set on the main body provides a precise pre-position for subsequent welding of the adjustment fixing block. This ensures that the installation reference of the tensioner in the transmission system originates from the main body 1 itself, thereby guaranteeing the adjustment accuracy and long-term stability of the belt or chain tension, and greatly improving the transmission efficiency and reliability.

[0049] like Figure 2 , 4 As shown in Figures 9 and 1, a process hole 32 is also provided on one side plate of the main body 1.

[0050] By setting the process hole 32, it can be used for positioning by the tooling fixture of the machining center when the main body 1 is being finished.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Various changes and modifications can be made to this utility model without departing from the claims, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
