Each positioning element 322 of the first embodiment is a spring positioning pin, which has the characteristic of being pushed and accumulated with the elastic force of returning to the original position, and is used to be clamped in the unfolding positioning hole 314 or the folding positioning hole 315, thereby positioning each foot tube 32 on the corresponding mounting seat 31.

Referring to fig. 3, 4 and 6, the exercise bicycle convenient to fold and carry can be switched between an unfolded state (as in fig. 3) and a folded state (as in fig. 6). In the unfolded state, the front telescopic pipes 222 extend from the front vertical pipe 221, the rear telescopic pipes 232 extend from the rear vertical pipe 231, the positioning members 322 of the foot pipes 32 are respectively engaged with the unfolding positioning hole portions 314 of the fixing plates 312, the two pairs of foot pipes 32 are unfolded outwards and are used for standing on the ground, the close sections 325 of the two pairs of foot pipes 32 are far away from each other, and the close section 325 of each foot pipe 32 is obliquely extended in a direction away from the base 21 compared with the respective pivoting section 323.

Referring to fig. 6 and 7, in the folded state, the front telescopic tube 222 is folded on the front vertical tube 221, the rear telescopic tube 232 is folded on the rear vertical tube 231, so that the heights of the front vertical tube 22 and the rear vertical tube 23 are reduced, and the two pairs of foot tubes 32 are folded and pivoted relative to the main frame unit 2 until the two pairs of foot tubes 32 face each other and are close to each other, at this time, the close sections 325 of the foot tubes 32 are close to each other, the positioning members 322 of the foot tubes 32 are respectively engaged with the folding positioning hole portions 315 of the fixing plates 312, and the close sections 325 of the foot tubes 32 are substantially parallel to each other and extend along the front-rear direction X. A reference line BL is defined through both the front and rear pivot points 324, and the converging sections 325 of the leg 32 are substantially parallel to each other in the collapsed state. With respect to being substantially parallel to one another, those skilled in the art will appreciate that tolerance, margin, or other non-ideal variations may accompany the product during manufacture or folding in use, if the converging portion 325 of the leg 32 deviates slightly from the reference line BL, it is within the scope of being substantially parallel to one another, as long as it is approximately horizontal.

The first embodiment is capable of being carried by a user with one hand by folding the front bellows 222 and the rear bellows 232 and pivoting the two pairs of foot tubes 32 to the folded state, since the first embodiment reduces the height in both the top and bottom orientations, minimizing the overall height and greatly reducing the volume.

Referring to fig. 4 and 8, the tread unit 4 includes a driving wheel set 41 rotatably disposed on the base 21, and a pedal crank set 42 for driving the driving wheel set 41 to rotate. The pedal crank set 42 has a shaft 421 rotatably penetrating the driving wheel set 41 along the left-right direction Y, two cranks 422 respectively fixed at the left and right ends of the shaft 421, and two pedals 423 respectively fixed at the cranks 422 for stepping, when a user steps on the pedals 423 in turn, the shaft 421 can be driven to rotate about its own axis through the cranks 422, so as to drive the driving wheel set 41 to rotate.

Referring to fig. 8 to 10, in detail, the driving wheel set 41 has a driving wheel 411 fixed on the shaft 421 and rotating along with the shaft 421, a driven wheel 412 driven by the driving wheel 411, an idle wheel 413 located between the driving wheel 411 and the driven wheel 412, a resistance wheel 414 driven by the driven wheel 412 and used for generating motion resistance, a main conveyor belt 415 rotatably sleeved on the driving wheel 411 and the driven wheel 412 and pressing against the top side of the idle wheel 413, a sub-conveyor belt 416 rotatably sleeved on the driven wheel 412 and the resistance wheel 414, a plurality of magnetic members 417 facing the resistance wheel 414, and a control member (not shown). The driven wheel 412 has a small wheel diameter section 4121 for engagement by the primary conveyor 415 and a large wheel diameter section 4122 spaced from the small wheel diameter section 4121 for engagement by the secondary conveyor 416. The resistance wheel 414 has a wheel body 4141 spaced from the driving wheel 411 and rotatably sleeved on the shaft 421, and a reluctance disc 4142 fixed to the wheel body 4141 and adjacent to the magnetic member 417. The magnetic members 417 are divided into two groups and are respectively located on the left and right wheel surfaces of the resistance wheel 414. When the resistance wheel 414 rotates, the reluctance disk 4142 rotates with respect to the magnetic member 417 and generates reluctance, thereby acting as a motion resistance. The adjusting member of the first embodiment is a steel cable, and is used to adjust the magnetic member 417, thereby adjusting the distance between the magnetic member 417 and the magnetic resistance disc 4142 in the left-right direction Y, so as to change the magnetic resistance.

In some variations, the driving wheel set 41 can also use friction force as the motion resistance, and the driving relationship between the wheels and the type of motion resistance can be properly selected or changed according to the actual requirements of the product, and these choices are not limitations of the present utility model.

Referring to fig. 11 to 13, a second embodiment of the exercise bicycle convenient for folding and carrying is similar to the first embodiment, and the main difference is that:

the main frame unit 2 further comprises a housing 20 for covering the base 21 and the transmission wheel set 41, and a handle is provided on the housing 20 for easy carrying. The number of front bellows 222 of the front pole group 22 is one.

Referring to fig. 12, 14 and 15, each of the mounting bases 31' has two spaced fixing pieces 312', and each of the fixing pieces 312' has a pivot hole (not shown).

Each leg 32 has a positioning member 322' having a thin plate shape and pivoted to the pivot hole of the corresponding fixing piece 312', and a tube 321 fixed to the positioning member 322'. The pivot point 324 of each leg 32 is formed in a respective positioning member 322'. Therefore, in the second embodiment, in the unfolded state (see fig. 12), the fixing piece 312 'of each mounting seat 31' is clamped against one side edge of the positioning piece 322', and in the folded state (see fig. 13), the fixing piece 312' of each mounting seat 31 'is clamped against the other side edge of the positioning piece 322'.

To sum up, in the folded state, the two pairs of leg pipes 32 are folded and pivoted relative to the main frame unit 2, so that the lengths of the two pairs of leg pipes 32 are shortened after folding, the total height of the folding device in the top-bottom direction Z can be reduced, the folded volume is reduced, and the folding device can be carried by a user with one hand, so that the folding device is convenient to fold and carry. Therefore, the novel purpose can be achieved.

While the utility model has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
