When the brake pad 160 and the flywheel 170 are in close contact, the braking purpose is achieved. However, using this method, the user can only adjust the resistance by feel, and the adjustment of the resistance cannot be intuitively understood.

[0004] In view of this, how to design a technology that can adjust the resistance size and improve user experience is the technical problem to be solved by the present invention. Utility Model Content

[0047] like Figures 2 to 4 As shown, the present application provides a resistance adjustment system, including a resistance adjustment handle, a resistance providing device, a brake cable 500 and a resistance detection device, which can accurately adjust the resistance size and detect and feedback the resistance size, thereby improving the user experience. Specifically:

[0048] The resistance adjustment handle is mounted on the frame 200 of the spinning bike, and is used to adjust the magnitude of the resistance.

[0049] The resistance providing device is installed on the frame 200 of the spinning bike. The resistance providing device is used to provide resistance to the wheel 300 and stop the wheel 300 from rotating. The resistance providing device is arranged near the outer edge of the wheel 300.

[0050] One end of the brake cable 500 is connected to the resistance adjustment handle, and the other end of the brake cable 500 is connected to the resistance providing device. The resistance adjustment handle tightens or loosens the brake cable 500 to change the resistance provided by the resistance providing device to the wheel 300, thereby achieving resistance adjustment.

[0051] The resistance detection device is also installed on the frame 200 of the spinning bike. The resistance detection device is connected to the resistance providing device. The resistance detection device can detect the specific value of the resistance provided by the resistance providing device, so that the user can plan his own exercise plan after obtaining it.

[0052] If the user wants to increase the resistance, he pulls the resistance adjusting handle, which tightens the brake wire 500, and the brake wire 500 pulls the resistance providing device to increase the resistance to the wheel 300. When the resistance is maximum, the wheel 300 stops rotating. If the user wants to reduce the resistance, he pulls the resistance adjusting handle in the opposite direction, which loosens the brake wire 500, and the brake wire 500 releases the resistance providing device to reduce the resistance to the wheel 300. During the resistance adjustment process, the resistance detection device can detect the size of the adjusted resistance in real time.

[0053] The resistance providing device includes an elastic member 600 and a resistance frame 700. The top end of the elastic member 600 is connected to the brake cable 500, and the bottom end of the elastic member 600 is connected to the frame 200. One end of the resistance frame 700 is connected to the top end of the elastic member 600, and the other end of the resistance frame 700 is hinged to the frame 200. A magnetic metal block 701 and a brake pad 702 are provided on the side of the resistance frame 700 close to the wheel 300.

[0054] When the brake cable 500 is tightened, the elastic member 600 is stretched, driving the resistance frame 700 to rotate closer to the wheel 300. The magnetic metal block 701 relies on magnetic attraction to slow down the wheel 300 until the brake pad 702 contacts the wheel 300 and stops it. When the brake cable 500 is relaxed, the elastic member 600 retracts, driving the resistance frame 700 to rotate away from the wheel 300. The attraction force of the magnetic metal block 701 on the wheel 300 becomes smaller, and the rotation speed of the wheel 300 increases.

[0055] The resistance frame 700 is arc-shaped, and the arc is adapted to the shape of the wheel 300. The brake pad 702 is arranged near the end of the arc-shaped resistance frame 700 away from the hinge. The magnetic metal block 701 is arranged on one side of the brake pad 702. The magnetic metal block 701 is a strong magnetic material. The magnetic metal block 701 includes multiple blocks, which are evenly arranged on one side of the brake pad 702 in sequence. The arc-shaped resistance frame 700 and the multiple magnetic metal blocks 701 make the resistance size change uniform, so that the wheel 300 can be decelerated smoothly, improving the safety and experience of use.

[0056] The elastic member 600 is a spring, which has a large elastic deformation and can provide a large resistance adjustment range. In addition, the spring is relatively low in price and easy to install, which can reduce manufacturing costs.

[0057] The resistance detection device includes a linear displacement sensor 800 and a processor (not shown in the figure). The telescopic rod 801 of the linear displacement sensor 800 is connected to the resistance frame 700. When the resistance frame 700 rotates, it will pull the telescopic rod 801 of the linear displacement sensor 800 to perform telescopic movement. The linear displacement sensor 800 and the processor are connected, and the change information of the telescopic rod 801 of the linear displacement sensor 800 is sent to the processor. The processor can convert the change information of the telescopic rod 801 into the size of the resistance. The process of the processor processing the change information of the telescopic rod 801 into resistance information is an existing technology and does not involve algorithm improvement, so it will not be elaborated here.

[0058] like Figure 2As shown, a connecting portion 703 is provided at one end of the resistance frame 700 close to the elastic member 600, the elastic member 600 is connected to the end of the connecting portion 703, and the telescopic rod 801 of the linear displacement sensor 800 is connected to the bottom of the connecting portion 703. The setting of the connecting portion 703 facilitates the uniform transmission of the movement of the resistance frame 700 to the linear displacement sensor 800, so that the resistance size obtained is more accurate.

[0059] The resistance adjustment handle includes a handle and a ratchet adjustment structure. The handle is connected to the brake line 500 through the ratchet adjustment structure. The ratchet adjustment structure is used to tighten or release the brake line 500. The ratchet adjustment structure can adopt a structure such as application number 202120862713.4, which will not be elaborated here.

[0060] During use, the resistance adjustment handle is pressed down, the ratchet adjustment structure tightens the brake cable 500, the elastic member 600 extends, the resistance frame 700 moves up, and the telescopic rod 801 of the linear displacement sensor 800 moves upward under the drive of the connection part 703, and the resistance of the magnetic metal block 701 to the wheel 300 increases until the brake pad 702 contacts the wheel 300, thereby braking; the resistance adjustment handle is pulled up, the ratchet adjustment structure loosens the brake cable 500, the elastic member 600 retracts, the resistance frame 700 moves down, and the telescopic rod 801 of the linear displacement sensor 800 moves downward under the drive of the connection part 703, the brake pad 702 separates from the wheel 300, and the resistance of the magnetic metal block 701 to the wheel 300 decreases until it reaches the minimum limit value.

[0061] In another aspect, the present application further provides a spinning bike, comprising:

[0062] Frame 200;

[0063] The wheel 300 is rotatably mounted on the frame 200;

[0064] The resistance adjustment system as described in any one of the above items is mounted on the frame 200 and is used to adjust the resistance of the wheel 300;

[0065] The display screen is connected to the processor of the resistance detection device and the linear displacement sensor 800. The display screen is used to display motion parameters, including the resistance size. When in use, the user can directly obtain various motion parameters such as the resistance size from the display screen, which is intuitive and clear.

[0066] The spinning bike also includes a communication unit, and the resistance detection device is connected to a remote terminal via the communication unit. The remote terminal is such as a mobile phone. When the display screen is damaged, the resistance size can be checked through the mobile phone.
