[0023] In order to provide a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed description is given in conjunction with the embodiments.

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 An electromagnetic damping riding platform according to an embodiment of the utility model includes a base plate 100, a housing frame 200, an electromagnetic core 300, a transmission device 400, an inertia wheel 500, a handle 600 and a controller;

[0025] The base plate 100 includes a U-shaped bottom plate 110 and a front plate 120, and the front plate 120 is in the shape of a seal fin. The U-shaped bottom plate 110 and the front plate 120 are fixed to the bottom of the shell frame 200; the structure of the base plate 100 ensures that the riding platform of the utility model is more stable, and the beam structure is converted into a plate-shaped supporting structure, which has a certain elastic deformation during riding, thereby realizing the simulation of riding a rubber tire.

[0026] Air holes 210 are respectively provided on both sides of the lower part of the shell frame 200, and a reinforcing plate 220 is fixed inside the shell frame 200. The reinforcing plate 220 is arranged in front of the inertia wheel 500, and a through hole 221 is arranged on the reinforcing plate 220. The air holes 210 are arranged to ensure good heat dissipation inside the shell frame. The reinforcing plate 220 in the shell frame 200 ensures the strength of the shell frame 200, avoids deformation of the shell frame 200, and extends the service life of the utility model. The through hole 221 design on the reinforcing plate 220 ensures free passage of air and ensures good heat dissipation inside the shell frame 200.

[0027] The inertia wheel 500 is installed in the housing frame 200, and the transmission device 400 includes a large pulley 410, a small pulley 420 and a belt 430. The large pulley 410 is rotatably connected to the housing frame 200 through a rotating shaft, and the riding platform flywheel is assembled on the rotating shaft through a tower base; when in use, the flywheel rotates, and the large pulley 410 is driven to rotate through the tower base. The small pulley 420 is concentrically arranged with the inertia wheel 500, and the inertia wheel 500 is rotatably installed in the housing frame 200 using a rotating shaft, and the large pulley 410 drives the small pulley 420 to rotate through the belt 430; a tensioning wheel is also arranged on one side of the belt 430 to adjust the tension of the belt 430 to achieve better rotation transmission. The transmission device 400 drives the inertia wheel 500 to rotate; the electromagnetic core 300 is fixed in the housing frame and is located outside the inertia wheel 500, the electromagnetic core 300 and the inertia wheel 500 are not in contact, a copper coil is wound on the electromagnetic core 300, and a handle 600 is also installed on the housing frame 200, an induction device is arranged in the handle 600, and the controller is connected to the induction device and the copper coil. A power interface can be set to connect to the controller, and the device is powered on, and an electromagnetic resistance device is formed by the inertia wheel 500 and the electromagnetic core 300. The copper coil is arranged on the electromagnetic core 300, and a magnetic field is generated under the action of the electromagnetic core 300 after power is turned on. When the inertia wheel rotates, it performs a relative motion of cutting the magnetic flux lines in the magnetic field formed by the electromagnetic core 300, and the inertia wheel 500 generates an induced current. The magnetic field generated by this induced current always hinders the relative motion between the inertia wheel 500 and the electromagnetic core 300, thereby realizing the electromagnetic resistance effect. By setting a sensing device in the handle 600, during use, the rotation or movement of the handle 600 is sensed, and the induced signal is transmitted to the controller. The controller controls the strength of the current passing through the copper coil, thereby controlling the adjustment of the magnetic field, realizing the adjustment of the resistance, and enabling better riding simulation.

[0028] Combination Figure 3The front plate 120 includes a fixing plate 121 and a supporting plate 122. The supporting plate 122 is fixed on both sides of the fixing plate 121. The fixing plate 121 is provided with screw holes 123 for fixing the housing frame 200 by bolt connection, so as to realize the detachable installation of the housing frame 200 and facilitate maintenance and transportation. The supporting plate 122 includes a connecting portion 1221 and a supporting foot portion 1222. One end of the connecting portion 1221 fixes the fixing plate 121. The connecting portion 1221 is tilted outward and forward and downward. The supporting foot portion 1222 is fixed to the other end of the connecting portion 1221. The fixing plate 121 is arranged horizontally. The supporting foot portion 1222 ensures that the utility model is more stable when placed on the ground to prevent shaking. The design of the connecting portion 1221 ensures that the overall structure of the front plate 120 is similar to the seal fin, has good support when riding, and can provide a certain elasticity, which can better simulate the natural riding feeling.

[0029] A reinforcing rib 124 is fixed to the bottom of the front plate 120. The reinforcing rib 124 connects the fixing plate 121 and the connecting portion 1221; the design of the reinforcing rib 124 ensures the support strength of the front plate 120 and avoids extending the service life of the front plate 120.

[0030] The U-shaped bottom plate 110 includes an upper plate 111, a lower plate 112 and an inclined connecting plate 113. The upper plate 111 is provided with a fixing screw hole, and the shell frame 200 is installed by passing a bolt through the fixing screw hole, which is convenient for disassembly and installation.

This design ensures that the U-shaped bottom plate 110 is more stable when used as a support plate, and the design structure of the U-shaped bottom plate 110 makes it have a certain flexibility and elasticity, which can provide a certain buffering and protection effect during use, increase elasticity, similar to the elasticity of a rubber tire, and more realistically simulate the feeling of a bicycle on the road.

[0031] Combination Figure 5The side of the reinforcing plate 220 is fixed on the shell frame 200.

The two sides of the arc-shaped connecting plate 224 are respectively connected to the first straight plate 222 and the second straight plate 223. The design of the arc-shaped connecting plate 224 ensures the strength of the reinforcing plate 220. At the same time, the structure is beautiful and not easy to deform, which ensures better support when in use and prevents the shell frame 200 from being deformed. The first straight plate 222 is vertically arranged, and the second straight plate 223 is inclined toward the inner side of the shell frame 200 from the connection with the arc-shaped connecting plate 224. The support range of the reinforcing plate 220 is increased, the strength of the reinforcing plate 220 is ensured, the shell frame 200 is prevented from being deformed, and the components in the shell frame 200 are protected.

[0032] like Figure 2 A cooling fan 230 is also installed inside the housing frame 200. By adding the cooling fan 230, the air flow speed in the housing frame 200 is fast and the heat dissipation effect is good, thereby ensuring high heat dissipation performance in the housing frame 200 and preventing heating during riding.

[0033] Combination Figure 5 , the angle between the first straight plate 222 and the second straight plate 223 is 120°-140°. The larger angle achieves more uniform stress distribution, improves the overall strength and durability of the reinforcing plate 220, extends the service life of the device, and prevents the shell frame 200 from deforming. At the same time, the structure fully considers the spatial structure layout, facilitates the installation of the inertia wheel, and effectively utilizes the space.

[0034] The U-shaped bottom plate 110 and the front plate 120 are both integrally connected and can be made by bending sheet metal or by making a whole plate.
