Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fitness equipment, in particular to a lifting fitness bicycle. BACKGROUND

[0002] The fitness bicycle is a common aerobic exercise equipment, which is widely used in gyms and home fitness. Using the fitness bicycle can effectively improve the heart and lung function, burn fat, and enhance the leg muscle strength, and it is also relatively easy to use, suitable for people of various fitness levels.

[0003] The existing bicycle has the function of riding, but it cannot simulate uphill or downhill function during riding. For example, the invention patent with publication number CN103977538A discloses a fitness bicycle, which comprises a handlebar, a seat cushion, a flywheel, a pedal and a vehicle body, a power generation assembly is fixed near the flywheel, the power generation assembly is composed of a silicon steel sheet iron core and an induction coil; a magnetic sheet is arranged on the flywheel, when the flywheel rotates, the magnetic pole will pass through the power generation assembly composed of the silicon steel sheet iron core and the induction coil, thereby changing the magnetic flux and generating an induced current. The core of the design is to convert the energy generated by the flywheel rotation of the fitness bicycle into electromagnetic induction through the designed device, and finally into electric power output. The output power is used to improve various functions of the fitness bicycle, realizing green fitness and scientific fitness. The invention patent has the conversion of exercise energy and electric power, but it does not have the function of simulating uphill or downhill.

[0004] For example, the invention patent with publication number CN118341038A discloses a fitness bicycle, which comprises a frame, a shifting member and a driving assembly. One end of the shifting member is movably connected to the handlebar of the frame, and the shifting member can be shifted by the hand holding the handlebar. The driving assembly is arranged on the handlebar of the frame, and the driving assembly comprises a load motor, a transmission mechanism and a pedal. The motor shaft of the load motor is drivingly connected to the pedal through the transmission mechanism. The fitness bicycle simulates the resistance received during the riding process by using the load motor to provide resistance, thereby canceling the traditional flywheel structure, which not only improves the safety, but also reduces the weight and the size. Moreover, the fitness bicycle sets the shifting member on the handlebar, so that the user can shift the shifting member when holding the handlebar, thereby adjusting the size of the resistance provided by the load motor. This adjustment method simulates the way of switching the control gear of the real bicycle, making the riding experience of the user more realistic and improving the riding experience of the user. The invention patent also does not have the function of simulating uphill or downhill.

[0005] For example, the patent with publication number CN108969988A discloses a fitness bicycle, which comprises a frame, a flywheel assembly and a pedal driving assembly arranged on the frame, the pedal driving assembly comprises a pedal, a toothed disc with chain teeth and a crank connecting the pedal and the toothed disc, the flywheel assembly comprises a flywheel and a sprocket arranged on a wheel shaft, the toothed disc and the sprocket are connected through a chain transmission, the sprocket is connected with a ratchet wheel, the wheel shaft is connected with a pawl and an elastic sheet, when the sprocket rotates clockwise, the pawl is automatically lifted under the action of the elastic sheet and is clamped in the tooth groove of the ratchet tooth, so that the sprocket drives the flywheel to rotate, when the sprocket rotates counterclockwise, the pawl is pressed down under the action of the ratchet tooth groove, and the sprocket and the flywheel are idling. The present application can make the exerciser safer and have a good exercise experience during fitness exercise. The patent focuses on safety, and does not have the function of simulating uphill or downhill.

[0006] In summary, the existing fitness bicycle lacks the function of simulating uphill or downhill. It is urgent to develop a fitness bicycle with the function of simulating uphill or downhill. Utility model content

[0007] Therefore, in order to solve the technical problem that the existing fitness bicycle does not have the function of simulating uphill or downhill, the utility model provides a lifting fitness bicycle, which drives the crank mechanism to drive the frame to lean forward or lean backward through the lifting device, so as to simulate uphill or downhill during riding. Not only solves the limitation of the traditional fitness bicycle, but also provides a more comprehensive and interesting exercise experience.

[0008] In order to achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0009] A lifting fitness bicycle comprises:

[0010] A base;

[0011] A lifting device arranged on the base;

[0012] A crank mechanism, one end of which is hinged to the frame, and the other end of which is hinged to the base;
