Description

A human-computer interaction spinning bicycle

technical field

The utility model relates to a human-computer interaction spinning bicycle, which belongs to the technical field of fitness equipment.

Background technique

Cycling is a systemic aerobic activity, which can effectively exercise the functions of human organs such as the brain and heart. Cycling not only has a lot of exercise, but also can get in touch with more scenery in the same time. However, with the acceleration of the pace of life, people prefer to choose to exercise at home or in the gym. The emergence of spinning bikes overcomes the disadvantages of outdoor cycling being affected by the environment, making this sport an aerobic exercise that can exercise the whole body while being easy to learn.

Most of the existing indoor spinning bikes, people can only sit on the seat and pedal to drive the flywheel to rotate, and the flywheel provides the resistance needed for people to exercise, the exercise process is monotonous, and the exerciser does not know the flywheel It is impossible to quantify the amount of exercise you have done because of the specific resistance. At the same time, most of the spinning bikes are exercised in the gym with strong sports music and the coach's command. It is difficult for the exerciser to grasp the exercise rhythm when exercising, and it is not suitable for users who like to exercise alone at home.

According to the novelty search, in the prior art, in 2016, Zhang Jianrui et al. applied for a utility model patent named "a VR spinning bicycle" with the publication number CN201610483597, which disclosed a VR spinning bicycle.

Example 3:

A method for using a human-computer interaction spinning bicycle, using the spinning bicycle described in Embodiment 1 or 2, the specific working process is as follows:

(1) Before using the user, first input the user's own height and weight on the display 1, set the initial riding resistance value and choose the sports scene you like; the built-in program of the single chip microcomputer can also be adjusted according to the user The input height and weight values automatically set the initial riding resistance value to achieve scientific fitness;

(2) Next, the user starts riding for fitness. When riding, the pedal 8 drives the magnetic powder brake 12 to rotate through the crank 9. The Hall sensor 14 detects the magnetic field change information of the magnet 13, which is amplified by the signal amplifier and then converted into a waveform. and shaping, input to the STC89C52 single-chip microcomputer, the single-chip microcomputer 15 controls the playback speed of the display 1 motion picture through the MAX232 serial port level conversion chip; when the user's riding speed changes, the playback speed of the display 1 motion picture also changes accordingly. The speed is adapted, that is, the playback speed of the picture is equivalent to the riding speed;

(3) When the user changes the set initial riding resistance value through the display 1 during riding, the display 1 transmits the newly set resistance value to the STC89C52 single-chip microcomputer through the MAX232 serial port level conversion chip, and the single-chip microcomputer 15 will receive The received information is output to the constant voltage source 16 through the PCF8951D/A digital-to-analog signal converter, and then the constant voltage source 16 controls the output resistance of the magnetic powder brake 12;

(4) When there was a slope (uphill or downhill) in the motion picture displayed by the display 1, the display 1 transmitted the slope information to the single-chip microcomputer 15, and the single-chip microcomputer 15 output the received information to the constant voltage source through the digital-to-analog signal converter 16. The constant voltage source 16 controls the output resistance value of the magnetic powder brake 12 to increase or decrease.

In addition, the motion picture played by the spinning bike can be recorded by the user in advance, imported to the spinning bike and background music is selected, and the riding time and riding distance are input and automatically generated by the system. It may also be a picture of a riding scene shared by others downloaded by the user from the database. It can also be an animation scene generated by the 3D modeling of the treadmill developer. At the same time, the current riding speed, riding resistance, riding time, riding distance and other information can be displayed on the display. Users can enjoy various roadside scenery on the curved display while exercising with a spinning bike, and can accurately obtain current exercise information. Users can choose to wear a VR helmet when riding, and can enjoy a more realistic picture while exercising, which has an immersive feeling and reduces the tedium of exercising.
