[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 shape. Its installation references are scattered and lack a unified, high-precision positioning structure. Furthermore, the large overall size and often long front support tube contribute to its bulkiness and high transportation costs. This makes it difficult for users to reassemble the core components, especially the electromagnetic backpack and flywheel assembly, after disassembly and transportation. Accumulated installation errors can lead to changes in critical working clearances or interference, resulting in decreased product performance, abnormal noises, or wear. Recalibration often requires specialized tools and techniques, leading to a poor user experience. It fails to ensure that users can easily and accurately restore the product to its factory condition after disassembly and reassembly, thus failing to overcome the performance degradation problem inherent in traditional products after disassembly and reassembly. Additionally, the often fixed, welded integrated design between the main body, front support, and bottom support tube also contributes to the product's large storage volume, increasing storage costs before transportation.

[0016] 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.

[0017] like Figures 1-14 As shown, an assembled cycling trainer bracket includes an integrated main body 1 and a front support 3; The integrated body 1 includes a body 1, a bushing 2, an electromagnetic backpack 21, and a flywheel assembly 22. The body 1 is integrally made of a rectangular tube, and the body 1 has an electromagnetic backpack mounting notch 10, a flywheel mounting port 11, and a bushing mounting hole 15. The bushing 2 is fixedly inserted into the bushing mounting hole 15, and the top end of the front support 3 is fixedly connected to the bushing 2; The two side plates of the flywheel mounting port 11 have corresponding semi-circular flange fixing ports 11-1, and a plurality of flywheel mounting holes 30 are provided at the edge of the semi-circular flange fixing ports 11-1. The main body 1 is positioned and mounted on the flywheel assembly 22 through the flywheel mounting holes 30. A flywheel clearance opening 31 is provided on the other side of the main body 1 corresponding to the semi-circular flange fixing port. The electromagnetic backpack mounting notch 10 is located on the opposite side of the flywheel mounting port 11 and adjacent to the flywheel clearance opening 31. A plurality of electromagnetic backpack mounting holes 10-1 are provided at the edge of the electromagnetic backpack mounting notch 10. The electromagnetic backpack installation area 10 is used to install the electromagnetic backpack 21 and to form a predetermined gap 23 between the electromagnetic backpack 21 and the flywheel assembly 22. The flywheel assembly 22 and the electromagnetic backpack 21 form an electromagnetic resistance device; The bottom end of the main body 1 is welded with a bottom support connecting plate 4 or a bottom rear support tube 5; the bottom end of the front support 3 is welded with a bottom support connecting plate 4.

[0018] This utility model utilizes a main body 1 integrally formed from a rectangular tube, with multiple key functional mounting holes directly formed on the main body 1, including an electromagnetic backpack mounting notch 10, a flywheel mounting port 11, a bushing mounting hole 15, a flywheel mounting hole 30, and an electromagnetic backpack mounting hole 10-1. This design eliminates the limitations of existing technologies where the main body of the support is often pieced together and welded from many iron plates, resulting in an irregular shape, scattered mounting references, and a lack of a unified high-precision positioning structure. This effectively reduces the number of parts and assembly steps, significantly improving the structural accuracy and stability of the main body. Simultaneously, the bushing 2 is fixedly inserted into the bushing mounting hole 15 and connected to the top of the front support 3, forming a stable herringbone-shaped foundation support frame. Based on this highly integrated structure, an innovative outer shell mounting support component is added. This support component is directly fixed to the main body 1 and the bushing 2, forming a stable frame for fixation, providing a dedicated mounting base for the cycling platform outer shell. This allows the outer shell to be installed independently and robustly, no longer relying on the attached connections of internal components of the main body. The symmetrical semi-circular flange fixing port and flywheel mounting hole 30 on the flywheel mounting port 11 ensure the precise positioning of the flywheel assembly 22, while the flywheel clearance port 31 avoids operational interference. The electromagnetic backpack mounting notch 10 is set on the opposite side of the flywheel mounting port 11, and the electromagnetic backpack 21 is installed through the electromagnetic backpack mounting hole 10-1, thereby forming a precise and stable backpack and flywheel predetermined gap 23 between the backpack and the flywheel assembly 22, ensuring the performance consistency of the electromagnetic resistance device.

[0019] Another core advantage of this utility model lies in its assembled bottom support design. The bottom end of the main body 1 can be selectively welded with a bottom support connecting plate 4 or a bottom rear support tube 5, or the bottom support connecting plate 4 can be used to connect a detachable bottom rear support tube 5. Simultaneously, the bottom end of the front support 3 is also welded with a bottom support connecting plate 4, making the bottom front support tube 6, which functions as the bottom, a separable independent component from the main body of the support. This assembled structure brings several substantial benefits. First, it allows users to flexibly configure bottom front support tubes 6 of different lengths according to actual usage needs. When extreme stability is required, a longer bottom front support tube 6 can be used, effectively increasing the support span, thereby significantly improving the cycling platform's anti-tipping ability and overall stability during intense riding. Second, this detachable structure greatly facilitates product packaging and transportation. Separating the generally long rod-shaped bottom front support tube 6 from the main body can significantly reduce packaging size, achieving a more regular packaging form. This not only reduces warehousing and logistics costs but also reduces the consumption of packaging materials. Finally, this design gives the product greater flexibility and adaptability. In the future, not only can the length of the bottom front support tube 6 be adjusted arbitrarily, but it can also be replaced with support tubes of different cross-sectional shapes or with special functions, such as adjustable height, to meet diverse user needs.

[0020] like Figure 5 , 10 As shown in 13 and 14, 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 provided on the detection channel of the sensor installed on the circuit board mounting hole 12 and the circuit board fixing hole 13.

[0021] 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 hole 14 is 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 hole 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 or 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, significantly improving maintainability and user experience.

[0022] like Figures 1-5 As shown in Figures 10, 13, and 14, an electromagnetic backpack mounting hole 10-1 serving as a positioning reference is provided at the edge of the electromagnetic backpack mounting notch 10. The electromagnetic backpack mounting hole 10-1 serving as a positioning reference is provided on the protruding part of the electromagnetic backpack mounting notch 10 of the main body 1 near the flywheel clearance opening 31.

[0023] The electromagnetic backpack mounting hole 10-1 is located on a special protruding part of the main body 1 near the flywheel clearance opening 31, ensuring the installation stability and unique positioning of the electromagnetic backpack 21. This mounting hole 10-1 is situated on the side of the electromagnetic backpack mounting notch 10 near the flywheel clearance opening 31, making full use of the structural space of the main body 1. The special protruding structure and the special hole position, combined with other electromagnetic backpack mounting holes on the electromagnetic backpack mounting notch 10, form a stable positioning system. This effectively prevents directional misassembly of the electromagnetic backpack 21 during assembly, ensuring that the orientation is absolutely correct every time. The electromagnetic backpack mounting hole 10-1, as an additional fixing point, significantly enhances the rigid connection of the electromagnetic backpack 21 on the side near the flywheel clearance opening 31, effectively suppressing any slight displacement or vibration that may occur during long-term operation. This maintains the stability of the crucial backpack-flywheel predetermined gap 23 between the electromagnetic backpack 21 and the flywheel assembly 22 for a long time, further ensuring the transmission accuracy and performance reliability of the electromagnetic resistance device, and improving the overall durability and user experience of the product.

[0024] like Figures 1-3As shown in Figures 5, 10, 12, and 14, the integrated main body 1 also has a wire binding hole 18, a wire clamping plate mounting hole 19, and a power cord hole 20.

[0025] 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 bundles, 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.

[0026] like Figures 1-10 As shown in Figures 12-14, the bottom end of the main body 1 is provided with a bottom support welding notch 29, and a bottom support connecting plate 4 or a bottom rear support tube 5 is welded onto the bottom support welding notch 29.

[0027] The bottom support welding notch 29 set at the bottom of the main body 1 can be directly welded to the bottom support connecting plate 4 or the bottom rear support pipe 5, thereby forming different forms of rigid connection nodes, such as assembled or welded types, which improves the ability of the main structure to resist lateral torsion. The modular welding and connection method, while ensuring the overall structural strength, is also convenient for production and transportation, which is an important optimization of the core performance and manufacturability of the product.

[0028] like Figures 1-5 As shown in Figures 10, 12-14, the main body 1 also has several outer shell clearance mounting holes 25, bicycle frame clearance recesses 26, and outer shell clearance notches 27.

[0029] 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.

[0030] 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.

[0031] like Figure 5 , 10 As shown in Figures 12-14, the integrated main body 1 also has several outer shell clearance mounting holes 25.

[0032] The housing clearance mounting holes 25 provided on the integrated main body 1 provide a direct mounting path for the housing, making the installation of the housing completely independent of internal functional components such as the flywheel assembly 22 and the electromagnetic backpack 21. This avoids interference or stress on precision gaps that may be caused by fixing the housing, thus creating a robust mounting system dedicated to the housing that does not rely on the calibration of internal components. This significantly improves the rigidity, reliability, and convenience of housing installation, while ensuring the long-term stability of the performance of the internal electromagnetic resistance device.

[0033] like Figures 1-4 As shown in Figures 6-9, 13, and 14, the main body 1 also has a tension wheel adjusting and fixing block welding port 28. A tension wheel adjusting and fixing block 9 is welded and fixed to the tension wheel adjusting and fixing block welding port 28. A tensioning hole 16 is provided on the tension wheel adjusting and fixing block 9. A tension wheel adjusting component tensioning and loosening limit mounting hole 17 for adjusting belt tension is provided on the side of the tension wheel adjusting and fixing block 9 of the main body 1.

[0034] The tensioner adjustment fixing block welding port 28 and tensioner adjustment fixing block 9 set on the main body provide precise pre-positioning 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 ensuring the adjustment accuracy and long-term stability of the belt or chain tension, and greatly improving transmission efficiency and reliability.

[0035] 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.

[0036] 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.

[0037] 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.
