The present invention relates to a system for manufacturing a customized bicycle frame using a motion analysis algorithm optimized for load and muscle power according to the motion analysis of the measured muscle power and measuring the user's lower body muscle power, and manufactured to have the same rigidity as the maximum rigidity of the user muscle power To provide a bicycle frame.

First, the muscular strength measuring unit collects data by measuring muscle strength by turning the pedal of the user, and the muscular strength measuring unit uses the frame, main body, pedal, saddle, and handle.

Includes.

The frame is connected to the main body, the saddle, and the handle. The frame supports the saddle and the handle when the user is exercising a bicycle.

The body includes a disc, crank and pedal. A rotatable disk is disposed inside the main body, and a crank capable of rotating the disk is connected to the rotation center of the disk. The crank is a rod extending in one direction, and the pedal is connected to the opposite direction of the portion where the crank and the disc are connected. Accordingly, when the user presses the pedal for bicycle exercise, power is transmitted through the crank, and the disc can rotate. The pedal and the crank are arranged on both sides of the disc, so that the user can exercise on both sides of the bicycle.

The saddle) is connected to the frame, the height can be adjusted so that the user can sit and step on the pedal.

The handle may further include a display unit and a sensor unit. The display unit may display information such as the speed of a bicycle, a moving distance, and an exercise time. In addition, information provided from the sensor unit may be displayed.

In addition, it is possible to provide an exercise amount suitable for an exercise purpose and an exercise goal based on information of a user input in advance.

The sensor unit may contact the user's body part to sense the user's body information. For example, the sensor unit may be a sensor capable of measuring the user's pulse, electrocardiogram, etc., when the user touches the handle, the sensor unit contacts the user's hand.

The display unit may receive data wirelessly and display contents of the received data.

Meanwhile, the muscle strength measuring unit may further include a smartphone. Since the smart phone is capable of wireless communication with a conventional smart phone, it is possible to receive data transmitted by the muscular strength measurement unit. Accordingly, the smart phone may communicate with the muscular strength measurement unit through an appropriate application program.

The muscle strength measuring unit may be applied to a general bicycle. For example, the muscle strength measuring unit may include a crank rotating about a rotation axis and a pedal connected to the crank. The crank and the pedal may have one side of the crank connected to the general bicycle instead of a disc.

In addition, the muscle strength measuring unit, the pedal includes a pedal housing, a strain gauge, a power generator, a first control unit and a transmitter for forming a space therein.

The crank can rotate about the rotation axis. A connection shaft connected to the crank is disposed in a direction opposite to the rotation axis of the crank. The connecting shaft can be fixed on the crank. Therefore, as the user presses the pedal, the crank rotates around the rotation shaft, and the connecting shaft is fixed on the crank, so that the crank can rotate relative to the pedal.

The power generation unit is disposed inside the pedal, and can supply power to the strain gauge, the first control unit, and the transmission unit. The power generator includes a first coil spaced apart from the connecting shaft and surrounding the connecting shaft. A second coil is wound on the connection shaft, and as the connection shaft rotates, an induced current is generated between the first and second coils to supply power to the strain gauge, the first control unit, and the transmission unit. You can.

The strain gauge is disposed above the pedal. The strain gauge may measure a force applied to the pedal by the user as the user presses the pedal. The strain gauge may be electrically connected to the first control unit and transmit measured data to the first control unit.

The first control unit is disposed inside the pedal, and can convert data received from the strain gauge as necessary. The first control unit is electrically connected to the transmission unit, and may transmit data to be transmitted by the transmission unit.

The transmitter may be disposed inside the pedal, and a portion may protrude outside the pedal. The transmitter may transmit data received from the first controller to an external device. For example, the transmitter may transmit the data to a smartphone or display. Wi-Fi or Bluetooth can be used to transmit the data.

The muscle strength measuring unit includes a bicycle exercise device including a pedal and a display unit.

The bicycle exercise device may be a general type of bicycle exercise device or an actual bicycle.

The pedal is a strain gauge disposed on the pedal so as to contact the user's foot, a first control unit that receives data measured by the strain gauge and performs appropriate calculation, and a transmission unit that transmits data received from the first control unit, And a power generation unit that supplies power to the first control unit.

The display unit includes a reception unit, a second control unit electrically connected to the reception unit, and a display device electrically connected to the second control unit, spaced apart from the pedal and capable of wireless communication with each other. For example, data transmitted from the transmission unit is received by the second control unit via the reception unit. Through the appropriate operation of the second control unit, data required by the user is extracted, and the data is displayed on the display device. For example, the user may evaluate and display the amount of exercise based on the force applied to the pedal, or display the strength and time of exercise to reach the preset amount of exercise based on the estimated amount of exercise. have.

On the other hand, although not shown, in evaluating the amount of exercise, as in the case of a conventional general bicycle exercise device, it is possible to refer to momentum data based on the rotational speed and rotational speed of a disk or wheel connected to a pedal.

Since the bicycle exercise system is substantially the same as the muscle strength measuring unit, except for the sensor unit of the display unit, repeated description is omitted.

The display unit further includes a sensor unit. The sensor unit may sense a user's body index such as heart rate and electrocardiogram. Data measured by the sensor unit may be transmitted to the second control unit, calculated in a required form, and displayed on a display device. For example, the user may evaluate and display the amount of exercise based on the force applied to the pedal, or display the strength and time of exercise to reach the preset amount of exercise based on the estimated amount of exercise. have. In addition, the exercise amount may be evaluated and displayed based on the evaluated exercise amount and the body index sensed by the sensor unit, or an exercise intensity and time for reaching a predetermined exercise amount may be displayed.

In addition, if the exercise analysis unit further included in the muscle strength measurement unit is described, the PC can generate, store, or output various types of exercise information based on the electrical signals derived from the sensor unit for analysis. Alternatively, storage and printing can be performed simultaneously.

As for the exercise information, at least one of a maximum point, a minimum point of the lower body muscle strength, a rising time for increasing muscle strength, and a falling time for decreasing muscle strength may be used. The exercise information generated by this corresponds to the maximum muscle strength, impact amount, quickness, and endurance of the user's foot.
