[0002] A cycling trainer is an indoor fitness device that mimics outdoor cycling. As people place increasing emphasis on their health, cycling trainers have become a common type of fitness equipment.

[0003] Existing smart self-generating cycling trainers typically use sheet metal for their main beams. Due to the large space and thickness of the power module, the internal support structure of these trainers is mainly made of sheet metal. Since the self-generating power module is assembled on one side, the sheet metal strength requirements are high, and the lateral displacement during riding is also significant. This places high demands on the quality of the sheet metal material, and the limited layout space makes it difficult to solve heat dissipation problems and the production process is complicated. This makes it inconvenient to install new self-generating modules and fails to provide stable and reliable support for the cycling trainer.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1-14 As shown, the cycling trainer of the present invention includes a housing, which includes a first housing 300 and a second housing 400 that are engaged with each other.

[0022] The cycling platform support structure of the present invention includes a support base 100, on which a support member 200 is vertically provided. The support member 200 extends into the housing and is connected to the housing.

[0023] The cycling train support structure of this invention is stable and reliable, with a compact and concentrated structure, providing stable and reliable support for the cycling train. The support base 100 is used to support and fix the entire cycling train, supporting the cycling train. The support member 200, while providing support for the cycling train, is also used to install components inside the housing, improving space utilization and enabling effective and reasonable layout of components, resulting in a compact and concentrated overall structure and small size for the cycling train.

[0024] The cycling platform in this invention is formed by sheet metal welding, which makes the overall weight lighter, the rigidity better, the production and processing easier, the shape more malleable, and the production efficiency improved.

[0025] In some embodiments of this application, the support base 100 is a hollow cuboid shape, formed by sheet metal welding. The support member 200 is also a hollow cuboid shape, formed by sheet metal welding. The top and bottom surfaces of the support base 100 are provided with interconnecting through holes 103. The support base 100 is vertically inserted and fixed in the two through holes 103. The fixing method can be a common fixing method in this technical field, and no specific limitation is made here.

[0026] The support base 100 is a hollow cuboid shape, which can be used to install the components of the cycling trainer, improving the space utilization rate and enabling the effective and reasonable layout of the components, making the overall structure of the cycling trainer compact and small in size.

[0027] In other preferred embodiments, the support base 100 and the support member 200 may also have other shapes and structures, which are not specifically limited here.

[0028] A reinforcing member is provided between the support base 100 and the support member 200, which can enhance the stability and reliability of the connection between the support base 100 and the support member 200, so that the support member 200 can be firmly and reliably fixed on the support base 100, effectively preventing the support member 200 from shaking or shifting; it can make the support base 100 and the support member 200 play a stable and effective supporting role, and make the entire cycling platform support structure stable and reliable, so that the cycling platform support structure can provide a stable and effective supporting role.

[0029] The reinforcing member is a single piece, which makes the reinforcing member structure stable and reliable. The reinforcing member includes a first reinforcing plate 121, which is obliquely fixed to the side wall of the support member 200 and the top surface of the support base 100. The top of the first reinforcing plate 121 is in close contact with the side wall of the support member 200, and the bottom of the first reinforcing plate 121 is in close contact with the top surface of the support base 100.

[0030] The first reinforcing plate 121, the side wall of the support member 200, and the top surface of the support base 100 can form a right triangle, which can effectively strengthen the stability and reliability of the connection between the support base 100 and the support member 200, and ensure that the support member 200 can be vertically fixed on the support base 100, so that the support member 200 can play an effective supporting role.

[0031] Second reinforcing plates 122 are symmetrically arranged on both sides of the first reinforcing plate 121, and both second reinforcing plates 122 are vertically connected and fixed to the side wall of the support member 200. The fixing method can be a common fixing connection method in this technical field, such as welding or bonding, and no specific limitation is made here.

[0032] The vertical distance M between the top of the support member 200 and the top surface of the support base 100 is approximately three times the vertical distance N between the top of the reinforcing member and the top surface of the support base 100, which ensures that the reinforcing member plays a stable and effective role in strengthening and reinforcing.

[0033] The width of the first reinforcing plate 121 is equal to the width of the side wall of the support member 200, or the width of the first reinforcing plate 121 is 5-10mm less than the width of the side wall of the support member 200, which can ensure that the reinforcing member plays a stable and effective role in strengthening and reinforcing.

[0034] The surfaces of the first reinforcing plate 121 and the second reinforcing plate 122 are shot blasted to facilitate oil removal and drainage.

[0035] The support base 100 is also provided with a leg connector, which is installed on the support base 100 and is located at one end of the support base 100. The two ends of the leg connector are respectively provided with rotatable legs 104, and the two legs 104 are located on both sides of the support base 100.

[0036] Specifically, the outrigger connector is a single piece, hollow rectangular, formed by sheet metal welding.

[0037] The outrigger connector includes two parallel first connecting plates 111 spaced apart vertically. A second connecting plate 112 is vertically connected to one side of the two first connecting plates 111, and two spaced third connecting rods 113 are vertically connected to the other side. The second connecting plate 112 has a through hole 114, which corresponds to the gap between the two third connecting rods 113. A support base 100 is fixed through and within the through hole 114 and the gap. The support base 100 is fixed within the through hole 114. The fixing method can be a common fixing connection method in this technical field, and no specific limitation is made here, so that the outrigger connector can be fixed on the support base 100.

[0038] Two first connecting plates 111 are located on the top and bottom surfaces of the support base 100, respectively. The length direction of the first connecting plate 111 is perpendicular to the length direction of the support base 100. Both ends of the first connecting plate 111 extend out of the top surface of the support base 100, and there is a gap between the first connecting plate 111 and one end of the support base 100.

[0039] The two support legs 104 are located at both ends of the first connecting plate 111 (outside the two third connecting rods 113), and the support legs 104 are rotatably connected between the two first connecting plates 111; the rotatable connection method is a common method in this technical field and is not specifically limited here.

[0040] When the two support legs 104 are closed, the support legs 104 are parallel to the support base 100, and there is a gap between the other end of the support legs 104 and the support base 100.

[0041] like Figure 10 , Figure 11 As shown, the first connecting plate 111 is not connected to the leftmost end of the support base 100, and there is a gap between the first connecting plate 111 and the leftmost end of the support base 100; the length of the support leg 104 is less than the length of the support base 100, and there is a gap between the rightmost end of the support leg 104 and the rightmost end of the support base 100; through the above settings, the support structure of the cycling platform can be made more concentrated and compact, and the support base 100 and the two support legs 104 can provide stable, firm and reliable support for the cycling platform, so that the cycling platform can be stably and firmly pressed against the ground without tilting or falling over.

[0042] The other end of the support 100 (such as...) Figure 11 As shown, the bottom of the support base 100 (which is the right end) is connected to a foot 105. The connection method can be a common connection method in this technical field, and no specific limitation is made here.

[0043] A turbine fan 101 is installed inside the support base 100. The installation method can be any of the commonly used installation methods in this technical field, and no specific restrictions are made here.

[0044] The top wall of the support base 100 is provided with a bottom air inlet 102 corresponding to the turbine fan 101. The turbine fan 101 corresponds to the heat sink 10 inside the housing, and the heat sink 10 is located directly above the bottom air inlet 102.

[0045] The support base 100 has a first air outlet 106 at one end and a second air outlet 107 at the other end.

[0046] In this embodiment, the support base 100 is a hollow cuboid shape, and one end of the support base 100 is open (e.g., Figure 10 , Figure 11As shown, one end of the support base 100 is the left end of the support base 100 (the left end of the support base 100 is open), and a perforated mounting sleeve 108 is fitted onto the opening of one end of the support base 100. The perforated part of the mounting sleeve 108 forms the first air outlet 106. By setting the mounting sleeve 108, on the one hand, it can protect the components installed in the support base 100, and on the other hand, it can form the first air outlet 106 on the mounting sleeve 108 to facilitate ventilation and heat dissipation.

[0047] The other end of the support 100 is not open (e.g. Figure 10 , Figure 11 As shown, the other end of the support base 100 is the right end of the support base 100 (the right end of the support base 100 is not open). A second air outlet 107 is provided on both side walls of the support base 100 near the other end. The second air outlet 107 includes a plurality of equally spaced elongated openings, which are arranged along the length of the support base 100.

[0048] A heating wire 109 is installed inside the support base 100. The heating wire 109 is close to the turbine fan 101 inside the support base 100 and extends out from one end opening of the support base 100. A guide groove 110 is provided on the top wall at one end opening of the support base 100, and the heating wire 109 extends out from the guide groove 110.

[0049] External cold air can enter the support base 100 through the bottom air inlet 102. Since the support base 100 has a first air outlet 106 and a second air outlet 107 at both ends, which are relatively close to the turbine fan 101 at the air inlet 102, it is easier to form negative pressure. Some of the cold air entering the support base 100 can flow out through the first air outlet 106 and the second air outlet 107, thereby reducing the internal flow channel distance, accelerating air flow, which is more conducive to heat dissipation and improving the heat dissipation effect.

[0050] The top wall of the support base 100 is provided with a fixing piece 130, which is located at one end near the support base 100; for example Figure 10 , Figure 11 As shown, the fixing piece 130 is positioned near the left end of the support base 100. Figure 2 , Figure 4 As shown, a first connecting post 131 is provided on the inner side of the first housing 300, and the first connecting post 131 is located near the bottom of the first housing 300; a connecting bolt is fixed between the first connecting post 131 and the fixing piece 130, thereby fixing the first housing 300 to the support base 100. Figure 6 As shown, the second housing 400 is provided with a second connecting post 132 on the inner side, and the second connecting post 132 is located near the bottom of the second housing 400; a connecting bolt is fixed between the second connecting post 132 and the fixing piece 130, thereby fixing the second housing 400 on the support base 100.

[0051] In this embodiment, the fixing piece 130 is positioned close to the center of gravity of the cycling platform, which allows the first housing 300 and the second housing 400 to be stably and reliably fastened and connected to the support base 100, making the cycling platform structure stable, reliable, and with high structural strength.

[0052] The support member 200 is vertically mounted on the support base 100, and extends into and is connected to the housing. The top side wall of the support member 200 and the housing are provided with a through hole 201, and the central shaft of the self-generating power module is connected in the through hole 201; the connection method can be a common connection method in this technical field, and no specific limitation is made here.

[0053] The top sidewall of the support member 200 is also provided with a first mounting hole 202 and a second mounting hole 206. The first mounting hole 202 is used to fix the guide screw and can provide axial shear force; the second mounting hole 206 is used to lock and fix the self-generating power module. The locking and fixing method can be a common fixing method in this technical field and is not specifically limited here. Through the above connection, the self-generating power module can be stably and reliably connected to the top of the support member 200.

[0054] The bottom side wall of the support member 200 is provided with a convection hole 203. The shape of the convection hole 203 can be circular, rectangular or other shapes, and no specific restrictions are imposed here.

[0055] Since a self-generating power module is installed on the top of the support 200, some of the heat generated by the self-generating power module will be transferred to the interior of the support 200. By setting convection holes 203 on the side wall of the support 200, the heat can be conducted out, allowing the heat inside the support 200 to flow out, avoiding the accumulation of heat inside the support 200 that cannot flow out, and effectively dissipating heat from the support 200.

[0056] The side wall of the support member 200 is provided with a mounting member 204 for mounting the heat sink 10. The mounting member 204 can be multiple mounting plates mounted on the side wall of the support member 200. The mounting plate is provided with a third mounting hole, and the third mounting hole is provided with a bolt for connecting the heat sink 10, so that the heat sink 10 can be mounted on the support member 200.

[0057] By setting the support component 200, the shell, the various components inside the shell and the support base 100 can be integrated into one unit, resulting in a highly integrated and compact structure. This reduces the number of parts, making the cycling platform compact, small in size, and with high space utilization. It also eliminates cumbersome processes such as welding and assembly, making it easier to manufacture and process, and its shape is highly malleable, thus improving production efficiency.

[0058] The first housing 300 is formed by sheet metal welding, which makes the overall weight of the first housing 300 lighter, without the influence of welding stress and overall deformation, and has good rigidity and heat dissipation.

[0059] The first housing 300 includes a first housing surface 301 and a first housing edge portion 302 formed around the first housing surface 301, the first housing edge portion 302 being formed by bending and extending from the first housing surface 301.

[0060] The first housing edge portion 302 includes multiple arc-shaped connected first housing edge branches, with corners between adjacent first housing edge branches. The first housing surface 301 is provided with a plurality of equally spaced protruding reinforcing ribs, which can make the first housing 300 structure stable and reliable.

[0061] The first housing includes a second housing surface 303, which is connected to the first housing surface 301 and is arranged along one side of the first housing surface 301.

[0062] The second housing surface 303 is provided with a fourth mounting hole 306, and the side wall of the support member 200 is provided with a side mounting plate 205. A bolt is connected between the fourth mounting hole 306 and the side mounting plate 205, so that the first housing 300 can be connected to the support member 200 and the support member 200 can be installed in the housing.

[0063] The first housing 300 includes a third housing surface 305, which is connected to the second housing surface 303 and is arranged circumferentially along the second housing surface 303.

[0064] The inner side of the third housing surface 305 is higher than the inner side of the second housing surface 303, and the inner side of the second housing surface 303 is higher than the inner side of the first housing surface 301.

[0065] A sixth housing surface 307 is formed around the periphery of the third housing surface 305. The sixth housing surface 307 is formed by bending and extending from the third housing surface 305, and the included angle between the sixth housing surface 307 and the third housing surface 305 is an obtuse angle. A detection through hole 308 is provided on the sixth housing surface 307, and a cadence detection component is installed in the detection through hole 308. The cadence detection component is used to detect cadence data. The cadence detection component includes a bracket 310, in which a groove is provided. An infrared plate 311 is installed in the groove, and a cover plate 312 is connected to the opening of the groove to cover it.

[0066] The first housing 300 and the second housing 400 are provided with a through-hole 410. Specifically, the third housing surface 305 on the first housing 300 is provided with the through-hole 410. In this embodiment, the through-hole 410 is rhomboid. In other preferred embodiments, the through-hole 410 can be circular, rectangular or other shapes, and no specific limitation is made here.

[0067] In this embodiment, the self-generated power module is installed on the top of the support member 200, and the flow-through hole 410 and the heat sink 10 are both located below the self-generated power module, with the flow-through hole 410 and the heat sink 10 located on both sides of the support member 200, respectively. The cadence detection component is installed on the sixth housing surface 307 and is positioned near one side of the flow-through hole 410.

[0068] By providing through-flow holes 410 in the first housing 300 and the second housing 400, the housing structure can be made more reliable and its structural strength increased. In addition, the through-flow holes 410 can also divide the cavity inside the housing and divert the airflow inside the housing, allowing the gas to flow quickly. When the turbine fan 101 in the support base 100 forms a negative pressure, the airflow will preferentially flow to the nearest channel, allowing the high-temperature gas inside the housing to flow quickly and dissipate heat rapidly, effectively preventing the infrared plate 311 from maintaining a high temperature, and providing effective heat dissipation protection for the infrared plate 311.

[0069] The support member 200 extends from the first housing surface 301 into the second housing surface 303 from bottom to top. The top of the support member 200 and the second housing surface 303 are provided with corresponding connecting through holes 201, which are connected to the central axis of the self-generating power module. The second housing 400 is provided with an adapter through hole 401, which is adapted to the module outer shell 501 of the self-generating power module.

[0070] In some embodiments of this application, the self-generating power module includes a module housing 501, a stator component 520 arranged inside the module housing 501, and an iron core arranged around the stator component 520. Coils 510 are wound around the iron core, and multiple coils 510 constitute a coil assembly. An air inlet gap 511 is formed between adjacent coils 510. The main heat source of the self-generating power module comes from the coil assembly of the self-generating power module, which includes multiple coils 510, with air inlet gaps 511 formed between adjacent coils 510. Since the coils 510 are intertwined, heat dissipation is difficult. To ensure effective heat dissipation, airflow should pass through the gaps between the coils 510 and over the surface of the coils 510, thereby carrying away the heat from the coils 510.

[0071] In order to allow airflow to pass through the air inlet gap 511 between the coils 510 as much as possible, this embodiment further improves the structure of the stator component 520 by providing a stator air outlet 521 on the stator component 520, which is disposed through the stator component 520; multiple stator air outlets 521 are provided, and the multiple stator air outlets 521 are arranged in an arc shape around the central axis of the self-generated power module.

[0072] The air inlet area of ​​the stator outlet 521 is at least twice the air inlet area of ​​the coil 510, and the sum of the cross-sectional areas of all air inlet gaps 511 constitutes the air inlet area of ​​the coil 510. In some embodiments of this application, since the coil 510 is arranged around the stator component 520 and close to the stator component 520, when a large area stator outlet 521 is provided on the stator component 520, better air pressure can be formed at the coil 510 near the large area air inlet 502, so that a large amount of airflow passes through the air inlet gap 511 of the coil 510, which can accelerate the removal of heat from the surface of the coil 510 and prevent the heat from rising too quickly.

[0073] The shape of the stator air outlet 521 can be round, square, etc., and there are no specific restrictions here.

[0074] The inner side of the first housing 300 is provided with an arc-shaped groove 320 and an arc-shaped sealing shell 330. The outer edge of the groove 320 and the outer edge of the sealing shell 330 are connected, and the inner edge of the groove 320 and the inner edge of the sealing shell 330 are connected. The groove 320 and the sealing shell 330 are connected to form an arc-shaped installation area, and an opening gap is formed between the groove 320 and the sealing shell 330.

[0075] In this embodiment, the groove 320 is disposed on the inner side of the third housing surface 305, and the sealing shell 330 is installed on the inner side of the second housing surface 303. The groove 320 and the sealing shell 330 are centered on the center of the connecting through hole 201. The surface of the groove 320 is basically flush with the surface of the sealing shell 330. The self-generating power module is installed in the installation area enclosed by the groove 320 and the sealing shell 330. The opening gap between the groove 320 and the sealing shell 330 constitutes the air inlet 502 of the self-generating power module.

[0076] A circular first sealing ring 341 is connected to the outer edge of the groove 320 and the outer edge of the sealing shell 330, and an arc-shaped second sealing ring 342 is connected to the inner edge of the groove 320 and the inner edge of the sealing shell 330.

[0077] In this embodiment, the second sealing ring 342 is arc-shaped, and its corresponding central angle is 270°-350°. For example, the central angle corresponding to the second sealing ring 342 can be 270°, 280°, 285°, 300°, 320°, 330°, 340° or 350°, and no specific limitation is made here.

[0078] The opening of the second sealing ring 342 faces downwards, and the opening of the second sealing ring 342 coincides with the air inlet 502 of the self-generating module. Vertically downward sealing strips 343 are provided at both ends of the opening of the second sealing ring 342, and the sealing strips 343 extend vertically downwards to the first sealing ring 341.

[0079] The first sealing ring 341 is annular, and a gap is formed between the first sealing ring 341 and the inner side of the second housing surface 303. This gap coincides with the air inlet 502 of the self-generating module.

[0080] The support member 200 extends from the first housing surface 301 into the second housing surface 303 from bottom to top. The support member 200 passes through the air inlet 502 of the self-generating module and extends into the second housing surface 303. The top of the support member 200 and the second housing surface 303 are provided with corresponding connecting through holes 201, which are connected to the central axis of the self-generating power module.

[0081] The first sealing ring 341 is arranged around the module housing 501 of the self-generating power module, and the second sealing ring 342 is arranged around multiple stator air outlets 521.

[0082] The air inlet 502 is connected to the interior of the self-generating power module and isolated by a sealing strip. The housing, the self-generating power module, and the sealing strip form a self-generating cavity, as the entire machine is enclosed by the housing. The turbine fan 101 is installed inside the support base 100, thus forming an inlet-outlet closed-loop channel with the outside. When the turbine fan 101 starts, a huge negative pressure is formed inside the entire housing. At this time, external cold air enters the housing through the air inlet 502. The cold air enters the housing and the sealed channel, and then the air enters the self-generating module cavity through the air inlet gap 511 of the coil 510. This can effectively cool the iron core coil 510. Under the influence of negative pressure, the air enters the entire machine from the motor cavity. This process can generate airflow around the coil 510, accurately carrying away heat from the coil 510. The air entering the self-generating module cavity can be discharged from the stator air outlet 521, exchanging heat and cold, thereby achieving a cooling effect and effectively dissipating heat from the self-generating power module.

[0083] The sealing shell 330, the first sealing ring 341, the second sealing ring 342 and the sealing strip 343 can guide and restrict the airflow through the self-generated power module, preventing the airflow from flowing out from the edge gap of the module shell 501. This allows the airflow to flow from the air inlet 502 into the air inlet gap 511 and then out from the stator air outlet 521, thus ensuring that the airflow can effectively cool and dissipate heat for the self-generated power module.

[0084] One of the thermistors is located in the enameled wire of the motor to monitor the temperature of the motor's enameled wire. Analysis shows that this is the highest temperature point of the motor, preventing the heat from rising too quickly. When the temperature remains high and exceeds the required temperature, the turbine fan will adjust its speed to increase heat dissipation.

[0085] The heat sink 10 can be made of aluminum, which provides good heat dissipation.

[0086] Circuit board 20 is mounted on heat sink 10. Circuit board 20 and heat sink 10 form multiple heat dissipation channels for heat dissipation of circuit board 20. The heat dissipation channels are connected to air inlet 502. Airflow can enter the heat dissipation channels through air inlet 502. Since the heat dissipation channels are composed of circuit board 20 and heat sink 10, when airflow enters the heat dissipation channels, it will inevitably carry heat on circuit board 20 and dissipate it, thus achieving the heat dissipation effect of circuit board 20.

[0087] Thermally conductive silicone is used to connect the circuit board 20 and the heat sink 10, which can increase the thermal conductivity and improve heat dissipation efficiency. The circuit board 20 includes a COS heating element, which is mounted and fixed on the circuit board 20 to prevent the circuit board 20 from overheating.

[0088] The MOSFET heating element features a unique aluminum heat dissipation fin design in areas where heat is concentrated. This not only increases heat dissipation but also enhances heat storage, preventing sudden temperature increases in the MOSFET heating element and the inability to dissipate heat in a timely manner, thus avoiding localized heat buildup and overheating. A heat dissipation aluminum fin 11 is also made on the heat concentration area of ​​the MOSFET heating element. The heat dissipation aluminum fin 11 is directly pressed onto the MOSFET heating element, so that the heat generated on the surface of the MOSFET heating element is directly conducted to the heat dissipation aluminum fin 11. The shape of the heat dissipation aluminum fin 11 is adapted to the shape of the MOSFET heating element, and the heat dissipation aluminum fin 11 is fixed on the aluminum heat sink 10, which facilitates heat conduction and increases the heat dissipation area.

[0089] The MOSFET heating element features a unique aluminum rib design at its concentrated heat-generating areas. This design not only enhances heat dissipation but also increases heat storage, effectively preventing the MOSFET heating element from overheating and causing localized heat buildup. The heat sink 10 is positioned directly above the turbine fan 101 and the bottom air inlet 102, with the heat dissipation fins 11 arranged vertically. A negative pressure is created between the turbine fan 101 and the bottom air inlet 102, directly below the heat sink 10. This allows air to flow rapidly across the heat sink 10 and the heat dissipation fins 11, and also allows more air to pass through the cooling airflow channels, effectively cooling the surfaces of the heat sink 10, the heat dissipation fins 11, and the circuit board 20.
