Although energy recovery schemes for generating electricity through fitness equipment have been proposed, there are few studies at home and abroad on how to efficiently generate electricity and its products. The fitness equipment that has been developed has low power generation efficiency, low power, poor portability, and high cost, which makes it difficult to popularize and adapt to the fitness needs of different age groups and different groups, and it is difficult to effectively realize energy recovery and storage. Therefore, it is necessary to design an energy recovery type sports fitness device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an energy recovery type fitness bike to solve the problems that the fitness equipment proposed in the above background technology has a single function and is difficult to achieve energy recovery; the existing fitness equipment has low power generation efficiency, low power, high cost, poor portability, and is difficult to popularize; and is not suitable for different age groups and different population needs.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An energy recovery type fitness bike comprises a forked detachable bracket, a circular frame of the vehicle body, a shaftless rack transmission system and a power generation system; the forked detachable bracket is located at the lower end of the fitness bike; the circular frame of the vehicle body is located at the upper part of the forked detachable bracket, the detachable saddle is fixedly installed on the upper part of the circular frame of the vehicle body through the upper slide groove of the circular frame of the vehicle body, and the middle part of the saddle rod is equipped with an upper slide groove of the saddle rod, which can adjust the position of the simple handlebar; the shaftless rack transmission system comprises a roller bearing, an annular driving wheel, a simple foot pedal and an annular rack; the power generation system consists of a bevel gear, a generator system and a display screen. A roller bearing is fixed closely to the inner wall of the frame, and an annular driving wheel is installed on the inner ring of the roller bearing through the bearing rotation, and simple foot pedals are installed at both ends of the driving wheel through bolts, and an annular rack is installed on the side of the driving wheel, and a bevel gear is installed at the lower end of the fitness bike to mesh with the annular rack, and the bevel gear is connected to the generator system. The generator system conducts the current after processing through the circuit placed inside the frame to the display screen installed above the simple handlebar.

[0007] The forked detachable bracket, the simple handlebar, and the detachable saddle are all detachable, the saddle rod is fixed to the upper part of the shell through a slide groove design, and the simple handlebar is also installed on the saddle rod through a slide groove design. The forked detachable bracket is composed of several crossbeams.

[0008] The transmission system adopts a shaftless design, and the overall structure is supported by a forked detachable bracket, a circular frame of the vehicle body, a roller bearing and an annular driving wheel.

[0009] The transmission system does not adopt traditional chain transmission, but gear transmission, and also adopts a flywheel-free structure. Damping during riding is provided by the generator system.

[0010] The body of the device adopts a circular structure, an overall ergonomic design, and a simple style.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] This energy recovery exercise bike is lightweight, detachable, easy to carry and suitable for multiple scenarios: the entire body is detachable. The two forks of the forked support can be folded together, and the upper connecting rod of the support is fixed to the frame by a buckle. It can be disassembled and folded together with the two forked bases to maximize space saving; the generator system, bevel gears and simple pedals can all be removed from the body; the main body structure of the body occupies a small area, and adopts a flywheel-free design, which is light in weight; the saddle rod adopts a retractable design, and the circular frame of the body and the saddle rod are equipped with slides, which can be adjusted according to personal needs. The ergonomic design is compared with the shortcomings of traditional spinning bikes that are very bulky and difficult to carry. All parts of this device can be disassembled and assembled, and it is light in weight and small in size. It can be installed and used in multiple occasions such as homes, gyms, schools, and companies, meeting the needs of different groups of people, expanding the audience range, and making it more convenient for market promotion.

[0013] Adopting a flywheel-free structure with high energy conversion efficiency: most of the general shared bicycles use traditional chain structure, belt structure or multi-stage gear for transmission. The transmission system only requires the meshing of the rack and the bevel gear to complete the transmission, reducing mechanical energy loss and improving energy recovery efficiency; in addition, most general shared bicycles use solid steel flywheels as the damping source, which are too heavy and inconvenient to move, and are not conducive to exercise for some people with poor physical fitness. This device uses a generator as the damping source, and controls the damping size through sensors, damping regulators and other devices to meet the exercise intensity requirements of different groups of people.

[0014] The generated electricity has a wide range of uses: the generator system transmits the current generated by the movement to the controller through wires. After processing the current, the controller transmits part of the current to the LED lights on the body of the vehicle, which not only makes it more beautiful but also enhances the atmosphere when riding. Another part of the current is transmitted to the display screen at the handlebars, which can display the current power generation. At the same time, it can also be transmitted to the battery at the generator system, and users can use this part of the electricity to charge their mobile phones and household appliances.

The shaftless rack transmission system includes a roller bearing 3, an annular drive wheel 4, a simple foot pedal 8 and a rack 5; the power generation system consists of a bevel gear 6, a generator system 7 and a display screen 11. A roller bearing 3 is fixed closely to the inner wall of the frame, and an annular drive wheel 4 is rotatably mounted on the inner ring of the roller bearing through the bearing. Simple foot pedals 8 are respectively mounted on both ends of the drive wheel through bolts, and a rack 5 is mounted on the side of the drive wheel. Figure 5 As shown, a bevel gear 6 is installed at the lower end of the fitness bike to mesh with a rack, and the bevel gear is connected to a generator system 7. The generator system processes the current and transmits it to a display screen 11 installed above the simple handlebar 10 through a circuit placed inside the frame. The display screen can display the power generation, visualize the fitness results and energy recovery.

[0024] The bracket 1, the simple handlebar 10, and the saddle 9 are all detachable in design and use a snap-on structure, which is easy to disassemble and assemble. The transmission system adopts a shaftless design, and the overall structure is supported by the bracket, the circular frame, the roller bearing and the driving wheel, making the overall device quite light. After disassembly, it can be lifted with one hand, which is convenient for carrying to different occasions for installation and use. At the same time, the transmission system does not adopt the traditional chain transmission, but adopts gear transmission, and adopts a flywheel-free structure. The damping during riding is provided by the generator system. This further reduces the weight of the vehicle body, and the damping size can be adjusted by the generator system, which can meet the exercise intensity requirements of different groups of people.

[0025] As shown in the generator system Figure 6 As shown, the generator system 7 is composed of a generator, a controller, a battery, an LED lamp, an inverter, a damping regulator, and a sensor. The generator is driven to generate electricity by the rotation of the bevel gear.

[0026] Working principle: A person sits on the saddle 9, holds the handlebars 10 with his hands, and steps on the simple pedals 8 with his feet, so that the driving wheel 4 can be stepped on and rotated. The driving wheel 4 can drive the rack 5 to rotate, thereby driving the bevel gear 6 to rotate, so that the driving rotor of the generator of the generator system 7 rotates. The electricity generated by the generator is transmitted to the LED light, the display screen 11 and the battery through the wire. At the same time, the damping regulator adjusts the damping by inducing current changes. The sensor senses the damping changes of the transmission system and then negatively feeds the signal to the damping regulator. Thereby, the purpose of adjusting the damping size during riding is achieved comprehensively. In summary, the purpose of sports fitness and energy recovery is achieved.

[0027] The exercise bike innovatively combines daily exercise and fitness with energy conservation and emission reduction technology. In addition, the project also strives to change the way people exercise - from focusing on how much energy is consumed to focusing on how much energy is recovered.
