[0030] The front end surface of the mounting frame 5 is provided with a handle, and the surface of the foot-operated wheel is a frosted surface.

[0031] The present invention has the following working modes: 1. Fitness walking mode, in which the user can drive the driving wheel 6 to rotate by running on the foot wheel, so that the fitness treadmill can move instead of walking. When this working mode is needed, the clutch 10 is adjusted so that the commutator 11 can drive the driving wheel 6 to rotate through the clutch 10 and the sprocket group; at this time, the user runs on the running belt 32, pedals the running belt 32, and the running belt 32 drives the foot wheel to rotate, the first foot wheel 12 rotates to drive the first sprocket group 16 to drive the second foot wheel 13 to rotate, the second foot wheel 13 rotates to drive the second sprocket group 17 to drive the third foot wheel 14 to rotate, the third foot wheel 14 rotates to drive the third sprocket group 18 to drive the fourth foot wheel 15 to rotate, the fourth foot wheel 15 rotates to drive the commutator 11 through the sprocket group, and the commutator 11 drives the clutch 10 so that the clutch 10 drives the driving wheel 6 to rotate through the sprocket group, and the running fitness vehicle can move at this time. In this mode, the weight of the user and the weight of the treadmill form a load on the treadmill wheel, increasing the force required by the user to pedal the treadmill belt 32, thereby enhancing the fitness effect.

[0032] 2. Parking fitness mode, in which the treadmill does not move, and the user only treadmills on the treadmill belt 32. When this working mode is needed, the clutch 10 is adjusted to separate from the drive wheel 6, and the DC motor 9 does not work. At this time, the rotation of the foot wheel drives the commutator 11 to idle, and does not drive the drive wheel 6 to rotate, so that the parking fitness mode can be achieved.

[0033] 3. Walking mode, in which the user only needs to stand on the running belt 32 without pedaling, and the DC motor 9 drives the driving wheel 6 to make the fitness treadmill move. When this working mode is needed, the clutch 10 is adjusted to connect the clutch 10 with the output end of the DC motor 9, and the DC motor 9 is started to drive the driving wheel 6 to run, so that the walking function can be realized.

[0034] 4. Indoor fitness mode, in this mode, the user can remove the detachable running device and put it indoors to run and exercise indoors. When this mode is needed, the locking handle is turned upward to make the locking handle in a vertical state. At this time, the locking sleeve loosens the locking block 29, and the user removes the locking sleeve from the locking block 29, holds the handle at the front end of the mounting frame 5, and lifts the detachable running device to place the detachable running device in the desired position as needed, and can run and exercise indoors. If it is necessary to switch from the indoor fitness mode to other modes, the detachable running device needs to be placed on the frame 1 again, and the installation guide groove 26 at the rear end of the mounting frame 5 is set outside the guide block, and the rear end of the installation guide groove 26 is against the front end of the limit block 27. At this time, the locking sleeve is put outside the locking block 27, and the locking handle is turned to a horizontal state. The locking sleeve firmly locks the locking block 27 to complete the installation of the detachable running device.

[0035] In the parking fitness mode and indoor fitness mode, the rotation of the foot wheel will also drive the generator 19 shaft to rotate for charging. The charged electric energy can provide power support for the DC motor 9 in the walking mode or fitness walking mode, which can save the power required for the walking function during the fitness process, which is more environmentally friendly and energy-saving. The seat 34 is usually flipped and set above the clutch 10. When the user is tired of running and fitness, the seat 34 can be flipped above the running belt and sit on the seat 34 to rest.

[0036] The present invention combines a running device with an electric vehicle to realize various functions such as running and fitness, parking and running fitness, and walking as a means of transportation; while running and fitness, the foot-moving wheel is connected to the generator through a sprocket set to realize the charging function, and the generator can be used as a power source for the DC motor to start the DC motor; the detachable running device can be removed separately to realize the fitness function.

[0037] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
