[Prior Art] When a bicycle player is playing a game, he or she will face different slopes of the actual road conditions. And it is usually necessary to run at a steady speed under different road conditions. Therefore, the physical strength and speed distribution required for actual road conditions are particularly important. 'This is enough to fully demonstrate the riding speed to win. For example, the structure of the exercise bike disclosed in the Republic of China Patent Application No. 95201595 'The exercise bike can provide a sporting effect close to that of a general bicycle. 'However, its function is simple, and it is impossible to provide a stable speed and a sloping road condition.

The control module is configured to receive the detection signal and convert it into a speed. a value, the control module has a speed range and a predetermined time, wherein when the speed value does not reach the speed range within the predetermined time, the control module outputs a prompt signal via the prompt group. When the speed value exceeds the speed range, the control module causes the frictional block to increase the friction of the wheel through the driving unit until the speed value decreases to the speed range, and then urges the friction block to the wheel. The frictional force is reduced. ^ The beneficial effect of the present invention is that, by using the speed range, the function of stable speed training can be provided by using the speed of the friction block, and the slope training function can also be provided. Therefore, the exercise bicycle with the speed control system of the present invention can meet the muscle strength and endurance training requirements of the bicycle player under actual road conditions when in use. [Embodiment] The foregoing and other technical contents 'features and effects of the present invention will be clearly shown in the detailed description of the preferred embodiment of the reference pattern below 201103602, as shown in Figs. 1, 2, and 3. A preferred embodiment of the exercise bike 200 of the present invention having a speed control system includes a vehicle body 20 and a speed control system. The vehicle body 20 includes a mat 21, a grip 22 in front of the seat cushion 21, a pedal unit 23 located below the seat cushion 21, and a wheel 24 coupled to the pedal unit 23.

The friction blocks 312 are respectively disposed on the movable arm 311 and facing the left and right sides of the wheel 24 On both sides. The driving unit 32 is disposed on the vehicle body 20, and the two movable arms 311 are synchronously yawed by pulling the brake wire 313. The driving unit 32 pulls the strength of the braking wire 3i3 to adjust the friction blocks 312. For the frictional force of the wheel 24, the driving unit 32 may employ a motor, a pneumatic cylinder, a hydraulic cylinder or the like as a driving element, and in the present embodiment, a motor is employed. The speed sensing unit 33 is configured to output a detection signal that changes with the rotation speed of the wheel 24, and the speed sensing unit 33 includes a plurality of magnets 331' that are respectively disposed on the side of the wheel 24, and are disposed at the side. The body 24 and the magnetic sensor 332 corresponding to the running track of the magnets 331, when the magnets 331 sequentially pass the magnetic sensor 332, the magnetic sensor 332 rotates the detection signal. When the safety switch 34 is actuated, the control unit 35 commands the drive unit 32 to maximize the friction of the friction blocks 312 to the wheels 24 to provide emergency braking. The control unit 35 is disposed on the vehicle body 20 and has a prompting module 36, an operating module 37, a transmission interface 38, and a control module 39 electrically connected to the foregoing modules. As shown in Figures 1, 2 and 5, the prompt module 36 has a screen % and a buzzer 362. The control module 39 can receive the detection signal output by the magnetic sensor 332 and convert it into a speed value 391. The control module 39 has a plurality of speed ranges, a predetermined time, and a display on the screen 361. The speed of the tracking line 390, in addition to the speed value 391, the control module 39 can also transport a cumulative mileage 392, a row of vehicle time 393, a cumulative calorie 394, and a frictional resistance 395, and both display On the screen 361. The speed tracking trace 390 is a change in the speed range over time. The speed value 391 is a continuously updated change and presents an actual speed line 391 on the screen 361 in contrast to the speed tracking trace 390. In the present embodiment, the speed ranges may be preset to 2〇km±10%′, tender, sample m±1G%, 5Qkm±1()%, 6()km+ 201103602, the predetermined time in this embodiment. It is 5 minutes. The = module 37 is used to select the _ speed range and the speed value pair, "adjust all control functions according to the individual physical condition, such as the speed range selected and the friction of the friction block 312 on the wheel Μ Etc., the operation module 37 is composed of a plurality of buttons in this embodiment t. The transmission interface 38 is used to update the data built into the control group 39, for example, to update the speed range and the service time. In this embodiment, the transmission interface 38 is an rs-232 interface. Figure 1 2 4, 5 does not, the following further describes the use case of the present invention, when the speed value 391 does not reach the selected speed within the time: the control module 39 will pass the prompt mode The group 36 outputs a No. 4 'in the embodiment, the prompt signal is via the buzzer, such as the sound of the sound, to remind the user that the current speed value is 391, and the force must be stepped on to meet the training requirements. When the speed value 391 exceeds the speed range, the control module 39 causes the frictional force of the friction blocks 312 to increase the friction of the wheel rim via the driving unit 32 until the speed value 391 decreases to the speed range. Further, the frictional force of the friction block 312 on the wheel 24 is reduced, and the user can reduce the pedaling force and maintain a stable traveling speed. Once the user selects the function of the speed tracking trace 390, the speed value 391 generated by the user currently stepping on will form the actual speed line 391, which is compared with the speed tracking trace 390, which follows the trace 39. The change in the speed range of the 〇 is based on the simulated actual road conditions. The user can use the speed planning of the speed tracking trace 390 to achieve the learning and distribution effect of the amount and speed of the 201103602. When the user needs to perform muscle strength and muscle endurance training for the uphill road section, the frictional force of the friction blocks 312 to the wheel 24 can be set via the operation module 37, thereby being necessary to use within the required speed range. More pedaling power to achieve training effectiveness. Therefore, it can be found from the above description that the function of the speed training can be provided by planning the speed range in use, and by providing the frictional force of the friction block 3丨2 to the wheel 24, the force month of the slope training can be provided. b Therefore, the exercise bicycle with the speed control system of the present invention can meet the requirements of the bicycle athletes for the muscle strength and endurance training under actual road conditions, and is only the preferred embodiment of the present invention. </ RTI> </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> <RTIgt; BRIEF DESCRIPTION OF THE DRAWINGS FIG. 2 is a block diagram showing a speed control and a speed sensing unit system in the preferred embodiment.
