[0038] The lower control part 2 is connected to the upper control part 1 through a signal line. The lower control part 2 is set on the same mainboard and includes a control module 23, a motor drive module 24 and a speed detection module 22. The lower control part 2 and the upper control part 1 can communicate by connecting through a 4-core signal line. The speed detection module 22 and the control module 23 are set on the same mainboard. There is no need to set up an independent signal line between the two, which can save costs, reduce external connection lines, and simplify the installation structure.

[0039] The control module 23 is used to process the received signal and adjust the output resistance of the motor drive module 24; the user can input the required exercise intensity through the command input and output module 12, and the control module 23 determines the resistance that the motor drive module 24 needs to output according to the input signal and adjusts the motor drive module 24 to output according to the set resistance.

[0040] The motor driving module 24, as the resistance source of the fitness bike, is used to drive the motor to output a set resistance. The structure and principle of the driving motor as the resistance source of the fitness bike are common technical means in the field of fitness bikes, and its structure and working principle will not be described in detail here.

[0043] Embodiment 2:

[0044] This embodiment provides a fitness vehicle having the control device in Embodiment 1. Figure 2 As shown, the fitness bike includes a frame, a handle is provided on the frame, and a mounting seat extending forward is provided in the middle of the handle, and the upper control part is arranged on the mounting seat and is arranged toward the user. In this way, the user can look down to view the content on the display module, which is in line with the user's operating habits. Preferably, a support frame is provided at the front end of the mounting seat, and the support frame includes a back plate for providing rear support and a first flange for providing bottom support; the first flange is located at the lower part of the back and folded upward to form a front limit for the peripheral equipment placed on the support frame.

Preferably, a second flange is symmetrically arranged on the left and right sides of the back plate, and the end of the second flange is folded inward to provide side limit for the peripheral equipment placed on the support frame. The first and second ribs provide bottom and side limits for the peripherals on the support frame to prevent them from falling off the support frame, thereby better protecting the mobile phones, tablets and other peripherals on the support frame.

[0045] Embodiment 3:

[0046] This embodiment provides a control method for an exercise bike, which is applied to the exercise bike in Embodiment 2. The method comprises the following steps:

[0047] After receiving the motion signal detected by the sensor head, the control module controls the control device of the fitness vehicle to turn on;

[0048] In the power-on state, the command input and output module receives the input work command and sends the work command to the control module;

[0049] The control module parses the received work instructions, controls the motor to rotate to a corresponding angle, and sends the corresponding display information to the display module for display.

[0050] In this embodiment, the speed of the fitness bike is detected by the sensor head. When it is detected that the speed changes from 0 to greater than 0, it means that a motion signal is detected, which indicates that the user is using the fitness bike. Therefore, in this embodiment, after the motion signal is detected, the fitness bike is controlled to turn on. Further, in this embodiment, after the fitness bike is turned on, if the sensor head continues to fail to detect motion information within a preset time, the fitness bike is controlled to turn off or enter a dormant state. The fitness bike is turned on and off based on the motion information, and the user does not need to perform additional on and off operations. After turning on, the fitness bike controls the motor to rotate to the corresponding angle according to the input command to output the resistance value set by the user. In this embodiment, the upper control part only performs command input and information display, does not perform data processing, and sends the input command to the lower control part for processing.

[0051] like Figure 3-4 As shown, the working instructions in this embodiment include resistance adjustment instructions and working mode switching instructions, wherein the input methods of the working instructions include point-click input and continuous-click input, and different instruction input methods correspond to different response methods. Figure 3 As shown, the user adjusts the resistance, the upper control part receives the resistance adjustment instruction input by the user, and determines whether the received signal is a tap input signal or a continuous press input signal. If the received signal is a tap input signal, the control module sends a single working instruction according to the preset motor working section, and controls the motor to rotate; if the received signal is a continuous press input signal, the control module sends a continuous working instruction according to the preset motor working section, and controls the motor to rotate.

[0052] like Figure 4 As shown, when the user makes a mode selection, the upper control part receives the mode selection instruction input by the user, and determines whether the received signal is a tap input signal or a continuous press input signal. If the received signal is a tap input signal, the control module executes a single switch of the program state and sends the data to the upper control part. After receiving the data, the upper control part lights up the corresponding icon and displays the corresponding function data at the same time; if the received signal is a continuous press input signal, the control module executes a carousel switch of the program state. The carousel switch refers to continuous switching according to a preset time interval and switching sequence, and sends the data to the upper control part. After receiving the data, the upper control part lights up the corresponding function when the carousel is displayed, and displays the corresponding function data at the same time.

[0053] This method provides the above-mentioned two modes of point-click input and continuous-click input, which can meet various input requirements of users and facilitate users to operate according to actual needs.

[0054] In this embodiment, the control module also performs abnormal detection and judgment. The control module detects the current of the motor in real time when it is working, compares the detected current with the set value, and determines whether the motor working current is normal. If the motor working current is detected to be abnormal, the control module sends the abnormal prompt to the upper control part for display. The fitness bike includes a motor position sensor for detecting the rotation angle of the motor. The motor position sensor is connected to the control module. The control module determines whether the motor or the motor position sensor is abnormal by comparing the signal returned by the motor position sensor with the motor drive signal sent by the control module to the motor. The control module is also used to determine whether the signal line connection is abnormal based on whether the signal transmitted by the signal line can be received. After detecting the above abnormality, the control module sends the corresponding abnormal prompt to the upper control part for display.

[0055] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
