[0030] In order to better understand the purpose, function and specific design of the present invention, the following is a further detailed description of the self-generating intelligent spinning bike with adjustable resistance of the present invention in conjunction with the accompanying drawings.

[0031] like Figure 1-12 As shown, the utility model comprises a front wheel 1 and a rear wheel 2, which are connected by a belt 3. The inner rail surface of the rear wheel 2 contacts the rotating shaft of the generator 4. The front wheel 1 is provided with a pedal 11. Pedal 11 can be used to rotate the front wheel 1, thereby driving the rear wheel 2 to rotate. The inner rail of the rear wheel 2 drives the generator 4 to rotate and generate electricity through friction. The generator 4 can input the output electrical energy into a battery and store it therein. The battery is connected to a display panel, and the display panel can be used for human-computer interaction. To improve transmission efficiency, the rear wheel 2 of this embodiment is arranged on the axle. One end of the belt 3 is mounted on the outer surface of the front wheel 1, and the other end of the belt 3 is mounted on the axle of the rear wheel 2. The outer ring diameter of the front wheel 1 is larger than the diameter of the axle.

[0032] Specifically, the inner rail surface of the rear wheel 2 is provided with a friction layer, which increases friction with the shaft of the generator 4. In this embodiment, the friction layer is made of rubber. The shaft of the generator 4 is also provided with a wear-resistant layer, which extends its service life. The wear-resistant layer is made of PU. Preferably, the wear-resistant layer is provided with wavy anti-skid grooves to further enhance friction between the friction layer and the wear-resistant layer, thereby ensuring transmission efficiency.

[0033] In this embodiment, the rotation of the generator 4 generates current, and then the AC power is converted into DC power through the rectifier bridge. The waveform of the input voltage is controlled by the PWM module, thereby storing the electrical energy in the battery. The battery continuously supplies 12V DC power to the display panel through the DCDC voltage stabilization module to ensure the normal operation of the display panel.

[0034] like Figure 3As shown, the self-generating intelligent spinning bike with adjustable resistance in this embodiment also includes a resistance adjustment component 5, which is connected to the belt 3. The resistance adjustment component 5 can adjust the tension of the belt 3, thereby adjusting the resistance when the foot is pedaling the pedal 11. The user can set multiple resistance levels for the spinning bike according to actual resistance requirements.

[0035] like Figure 3-6 As shown, the resistance adjustment assembly 5 includes a support base 51, a rebound hook 52, and a transmission rod 53. The rear wheel 2 is rotatably mounted on the support base 51 via a wheel axle. The support base 51 is provided with a movable groove 511. Below the movable groove 511, multiple oblique limiting grooves 512 arranged side by side and spaced apart are connected. This embodiment is described using three oblique limiting grooves 512 as an example. A limiting post 521 is provided on the side of one end of the rebound hook 52. The limiting post 521 can move within the movable groove 511 and be engaged within the oblique limiting groove 512. The other end of the rebound hook 52 is connected to the pressure wheel 54, which contacts the belt 3. One end of the transmission rod 53 is connected to the limiting post 521. Pulling the transmission rod 53 can switch the limiting post 521 between different oblique limiting grooves 512, thereby changing the pressure of the pressure wheel 54 on the belt 3 to achieve the function of adjusting the resistance when the pedal 11 is pedaled.

[0036] The transmission rod 53 is connected to the adjustment wire 55, and the adjustment wire 55 is connected to the shifter. The shifter is set on the handlebar. The shifter can pull the adjustment wire 55 to move, thereby pulling the transmission rod 53 to move to achieve gear shifting.

[0037] Specifically, a lever arm 56 is provided on the support seat 51, and the middle position of the lever arm 56 is hinged to the support seat 51, one end of the lever arm 56 is connected to the rebound hook 52, and the other end of the lever arm 56 is provided with a compression wheel 54. By moving the limiting column 521 and clamping it in different oblique limiting grooves 512, the rebound hook 52 can drive the lever arm 56 to rotate to different angles, thereby changing the pressure of the compression wheel 54 in the vertical direction of the belt 3, so as to change the tension of the belt 3, thereby changing the resistance when the foot is pedaling 11.

[0038] It is worth noting that, in order to improve the degree of automation of the resistance adjustment assembly 5, the resistance adjustment assembly 5 of this embodiment further includes a resilient piece 57. The resilient piece 57 is provided with a transverse groove 571. The lower end of the transverse groove 571 is provided with an oblique groove 572, which is connected to the oblique groove 572. The transverse groove 571 on the resilient piece 57 is the same width as the movable groove 511, but is shorter than the movable groove 511. The oblique groove 572 on the resilient piece 57 is the same width and slope as the oblique limiting groove 512, but there is only one oblique groove 572 on the resilient piece 57. The support base 51 is provided with a slot 513. The resilient piece 57 is movable within the slot 513. The transverse groove 571 on the resilient piece 57 and the movable groove 511 overlap in the length direction. Therefore, when the resilient piece 57 moves within the slot 513, the oblique groove 572 can overlap with different oblique limiting grooves 512.

[0039] The limiting post 521 of the rebound hook 52 passes through the support base 51 and is disposed on the rebound plate 57. The end of the limiting post 521 is connected to the transmission rod 53. The end of the rebound hook 52 away from the limiting post 521 is connected to a return spring 58, which can provide a restoring force for the rebound hook 52. In this embodiment, the return spring 58 is connected to the end of the lever arm 56 connected to the rebound hook 52.

[0040] In actual use, the resistance adjustment assembly 5 of this embodiment is described by taking three oblique limiting grooves 512, i.e., three gears, as an example. Figure 3 As shown, at this time, the limiting column 521 is engaged in the leftmost oblique limiting groove 512, that is, in the third gear. At this time, by pulling the adjustment line 55, the transmission rod 53 is driven to move, so that the limiting column 521 of the rebound hook 52 moves out from the leftmost oblique limiting groove 512 and the oblique groove 572, enters the moving groove 511 and the horizontal groove 571 and moves to the leftmost side, as shown in FIG. Figure 7 As shown, at this time, the oblique limiting groove 512 is misaligned with the oblique groove 572, and the rebound hook 52 pulls the limiting column 521 to the leftmost side of the transverse groove 571 under the action of the return spring 58, as shown in FIG. Figure 8 As shown, the limiting column 521 then drives the rebound sheet 57 to move until it moves to the position shown in FIG. Figure 9 As shown in the figure, the limiting post 521 moves to the rightmost side of the moving groove 511, and then due to the fast movement speed of the limiting post 521, it will rebound after hitting the rightmost inner wall of the moving groove 511 and move a short distance to fall to the position shown in the figure. Figure 10 The position shown in FIG. 5 shows a position where the limiting post 521 is engaged in the rightmost oblique limiting slot 512, i.e., the position of the first gear. It is understandable that when adjusting the resistance during riding, the vibration of the vehicle body itself may also cause the vehicle to move. Figure 9 The limiting post 521 in the position shown is moved to Figure 10 The rightmost oblique limiting groove 512 is shown.

[0041] When switching from the first gear position to the second gear position, the adjustment line 55 is pulled to drive the transmission rod 53 to move, so that the limiting column 521 moves out of the rightmost oblique limiting groove 512 and the oblique groove 572, enters the moving groove 511 and the horizontal groove 571 and moves to the position as shown in FIG. Figure 11 As shown, under the action of the return spring 58, the limit column 521 is pulled to the right, and the oblique groove 572 coincides with the middle oblique limit groove 512. The limit column 521 will fall into the middle oblique limit groove 512 due to gravity, as shown in FIG. Figure 12 As shown, the shift from the 1st gear position to the 2nd gear position is now completed. When switching from the 2nd gear position to the 3rd gear position, the action of switching from the 1st gear position to the 2nd gear position is repeated, and no further details are given here.

[0042] This innovative design features an ingenious structure. By creating friction between the inner rail of the rear wheel and the generator's shaft, the device significantly increases the generator's rotational speed, thereby improving power generation efficiency. Furthermore, the device uses self-generated electricity to power the display panel, enabling human-computer interaction. This design is both environmentally friendly and energy-efficient, significantly enhancing the user experience. Furthermore, through a purely mechanically limited resistance adjustment component, the device can meet customer resistance adjustment needs at a low cost.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
