Description
BACKGROUND OF THE INVENTION
1. Technical Field
[0001] The invention belongs to the technical field of fitness
equipment, in particular to a resistance-adjustable stationary
bicycle capable of realizing electrical adjustment of the

2. Description of Related Art
[0002] Magnetic damping washers are usually adopted by stationary
bicycles to control the rotational resistance of the flywheel, that
is to say, the frictional resistance between the magnetic damping
washers and the flywheel can be adjusted to adjust the treading
resistance of the pedals of the stationary bicycles.
[0003] In the prior art, the relative positions of the magnetic
damping washer and the flywheel are generally manually adjusted to
adjust the resistance of the stationary bicycles. However, the
existing stationary bicycles have the following defects: (1) in
order to meet the requirements for different resistances of
operators in different performance statuses, the resistance should
be rapidly and easily adjusted in the fitness process; and (2)
under the condition of constant-resistance fitness, the resistance
between the magnetic damping washer and the flywheel will be
decreased when the magnetic damping washer is worn, which in turn
leads to a non-uniform resistance, and in this case, the resistance
should also be adjusted in time.
[0004] In view of these defects, Chinese Utility Model Patent

wheel and an electromagnet component, the inertia wheel is mounted
at the bottom of the front support, and the electromagnet component

with the inertia wheel so as to form a resistance against the
inertia wheel; and the pedal wheel mechanism is mounted on the
lower portion of the front support, is located above the inertia
wheel mechanism, and is linked with the inertia wheel
mechanism.
[0005] According to this technical solution, the resistance of the
inertia wheel is accurately controlled through the electromagnet
component; however, the electromagnet component is high in energy
consumption and has a structural stability poorer than that of the
magnetic damping washer. Thus, there is an urgent need for a
magnetic damping washer-based stationary bicycle with the
resistance capable of being conveniently and rapidly adjusted.

components in the figures are not drawn to scale, and similar
reference signs generally represent similar components.
[0020] The invention is further expounded below with reference to
the accompanying drawings and embodiments.
[0021] As shown in FIG. 1 and FIG. 2, this embodiment provides a
resistance-adjustable stationary bicycle which comprises a frame
10, wherein a magnetic damping washer 4 and a flywheel 11 are
arranged on the frame 10, a permanent magnet layer is arranged on a
peripheral wall of the flywheel 11, one side of the magnetic
damping washer 4 is provided with a permanent magnet block to serve
as a brake side, and the magnetic damping washer 4 is movably
arranged close to the periphery of the flywheel 11.
[0022] Particularly, one end of the magnetic damping washer 4 is
hinged to the frame 10 through a rotary shaft, the other end of the
magnetic damping washer 4 is elastically connected to the frame 10
through an elastic piece, and the elastic piece is able to apply a
force to make the magnetic damping washer 4 swing towards the
flywheel 11. Preferably, a mounting plate is further arranged on
the frame 10 and is fixed to a side, away from the flywheel 11, of
the magnetic damping washer 4 on the frame 10, that is to say, the
free end of the magnetic damping washer 4 is arranged between the
mounting plate and the flywheel 11. Moreover, the elastic piece is
preferably a compression spring having two ends respectively
abutting against the mounting plate and the free end of the
magnetic damping washer 4 so as to apply a force towards the
flywheel 11 to the free end of the magnetic damping washer 4.
Meanwhile, in order to prevent excessive swing of the magnetic
damping washer 4, a limiting rod is arranged on the mounting plate,
and the top of the limiting rod penetrates through the magnetic
damping washer 4 to be connected with a limiting block, so that the
magnetic damping washer 4 is limited.
[0023] To fulfill easy adjustment and control of damping, a
controller 1, an adjustment motor 3, and an adjustment knob are
further arranged on the frame 10. In this embodiment, the
adjustment knob is arranged on a handle part 2; the controller 1 is
electrically connected with the adjustment motor 3 and the
adjustment knob, and then the adjustment motor 3 is connected to
the free end of the magnetic damping washer 4 through an adjustment
steel rope 34 particularly in such a manner: the adjustment steel
rope 34 penetrates through the mounting base and is then hooked on
the free end of the magnetic damping washer 4.
[0024] In this embodiment, damping adjustment is realized in the
following way: the controller 1 reads the rotation variables of the
adjustment knob on the handle part 2, namely the rotation direction
and the rotation angle, to control the adjustment motor 3 to wind
or unwind the adjustment steel rope 34, so as to control the swing
angle of the magnetic damping washer 4 (to adjust the distance
between the magnetic damping washer 4 and the flywheel 11), so that
resistance adjustment is realized.
[0025] In this embodiment, the frame 10 comprises a bottom frame
horizontally placed on the ground, a seat support provided with a
seat, and a handlebar support provided with a handlebar part,
wherein the seat support and the handlebar support are fixed to the
bottom frame in a V shape, and the handle part 2 is arranged in the
middle of the handlebar support in a vertical direction and exactly
faces a position vertically below the arms to fulfill the optimum
ergonomic effect, so that the adjustment knob of the handle part 2
can be adjusted most conveniently.
[0026] Furthermore, the controller 1 is connected with a
communication module. Preferably, the communication module is a
Bluetooth communication module through which the controller 1 is
connected to a handheld electronic terminal device such as a mobile
phone or a tablet computer, so that an operator can input parameter
values to the controller via an APP on the external handheld
electronic terminal device to control the adjustment motor 3 to
work and thus realize resistance adjustment.
[0027] Referring to FIGS. 3-5, the resistance-adjustable stationary
bicycle in this embodiment further comprises an emergency braking
system. The emergency braking system comprises a brake pad 5 and a
steel brake cable 6. The handle part 2 is pivoted to the handlebar
support through a rotary shaft, the brake pad 5 is pivoted to a
position, close to the flywheel 11, of the frame 10, and two ends
of the steel brake cable 6 are eccentrically connected to the
handle part 2 and the brake pad 5 respectively, so that the handle
part 2 and the brake pad 5 are linked together.
[0028] Particularly, a crank is arranged at the lower end of the
handle part 2, and one end of the steel brake cable 6 is hooked on
the crank; the other end of the brake pad 5 is pivoted to the frame
10 and is provided with a tension spring 51 so as to be elastically
connected to the frame 10 through the tension spring 51 or to move
away from the flywheel 11 under the elastic effect; the steel brake
cable 6 is connected to the brake pad 5; and when the handle part 2
is swung around the axis from top to bottom, the steel brake cable
6 is tensioned to apply a force to the brake pad 5 which in turn
overcomes the resistance from the tension spring 51 to rotate to
abut against the periphery of the flywheel 11, so that emergency
braking is realized.
[0029] Although the invention is specifically illustrated and
introduced in combination with preferred embodiments, those skilled
in the art would appreciate that variations of the invention can be
made in forms and in details without deviating from the spirit and
scope defined by the claims, and all these variations should also
