[0076] like Figures 1 to 8As shown, this utility model embodiment provides a rocking-pedal synchronized fitness training framework and device, including a recumbent bike assembly 1, a front armrest fixing tube assembly 2, an electronic watch 3, a hand crank assembly 4, a locking knob assembly 5, a front leg tube assembly 6, a bottom tube assembly 7, a rear leg tube assembly 8, a rear frame assembly 9, a seat cushion front-to-back adjustment track 10, a seat back cushion assembly 11, a left handlebar assembly 12, a right handlebar assembly 13, a resistance adjustment assembly 14, a left pedal 15, and a right pedal 16. This allows for effective coordinated exercise of all four limbs through the recumbent bike assembly 1 in conjunction with the handlebar assembly, significantly improving the comprehensiveness of the workout. Simultaneously, the seat cushion front-to-back adjustment track 10 and the resistance adjustment assembly 14 effectively enhance the functional adaptability and flexibility for different body conditions, thereby improving the overall functionality and practicality of the device. Specific settings are as follows:

[0077] Please refer to Figures 3 to 7 The horizontal car assembly 1 includes a horizontal car body and a first synchronous pulley 1-1, a synchronous belt 1-2, a second synchronous pulley 1-3, a left pedal bracket 1-4, a left turntable 1-5, a left outer shell 1-6, a pulley 1-7, an inner magnetic flywheel 1-8, a transmission belt 1-9, a right pedal bracket 1-10, a right turntable 1-11, and a right outer shell 1-12, respectively, mounted on the horizontal car body. The first synchronous pulley 1-1 and the second synchronous pulley 1-3 are respectively rotatably mounted on the horizontal car body, and the synchronous belt 1-2 is respectively driven around the first synchronous pulley 1-1 and the second synchronous pulley 1-3 to form a belt drive path between the first synchronous pulley 1-1 and the second synchronous pulley 1-3.

[0078] The left pedal bracket 1-4 is fixedly connected to the left turntable 1-5, and the right pedal bracket 1-10 is fixedly connected to the right turntable 1-11, and the two are symmetrically arranged. The left pedal bracket 1-4 and the right pedal bracket 1-10 are coaxially connected to the second synchronous belt pulley 1-3, and the left pedal 15 is eccentrically connected to the left pedal bracket 1-4, and the right pedal 16 is eccentrically connected to the right pedal bracket 1-10. When the left foot presses the left pedal 15, the left pedal 15 drives the left turntable 1-5 and the left pedal bracket 1-4 to rotate synchronously. At the same time, when the right foot presses the right pedal 16, the right pedal 16 drives the right turntable 1-11 and the right pedal bracket 1-10 to rotate synchronously. Thus, by transmitting power to the second synchronous belt pulley 1-3 at the same speed through the left pedal bracket 1-4 and the right pedal bracket 1-10, the overall transmission function stability is improved.

[0079] The left outer shell 1-6 and the right outer shell 1-12 are respectively fixedly assembled to the horizontal vehicle body, and the left outer shell 1-6 and the right outer shell 1-12 are respectively correspondingly covered on the outside of the left turntable 1-5 and the right turntable 1-11, so as to protect the internal transmission components through the left outer shell 1-6 and the right outer shell 1-12, prevent impurities from entering, and at the same time prevent the user from contacting the transmission components and causing injury.

[0080] In a preferred embodiment, the belt pulley 1-7 and the second synchronous belt pulley 1-3 are coaxially connected. The inner magnetic flywheel 1-8 is rotatably mounted on the horizontal carriage body. The belt pulley 1-7 is connected to the inner magnetic flywheel 1-8 via the transmission belt 1-9, which provides motion resistance through the inner magnetic flywheel 1-8 and feeds it back to the belt pulley 1-7 and the second synchronous belt pulley 1-3 in real time via the transmission belt 1-9, thereby realizing the adjustment of the rotational resistance of the corresponding second synchronous belt pulley 1-3.

[0081] Specifically, the resistance adjustment component 14 is mounted on the horizontal vehicle body in a height-locking manner. The resistance adjustment component 14 has a knob end and a magnetically controlled resistance adjustment rod 14-1. The knob end and the magnetically controlled resistance adjustment rod 14-1 are connected by a ball screw mechanism. The magnetically controlled resistance adjustment rod 14-1 and the inner magnetic flywheel 1-8 are magnetically attracted to each other in an adjustable manner. By rotating the knob end of the resistance adjustment component 14, the rotational motion of the knob end is converted into linear motion of the magnetically controlled resistance adjustment rod 14-1 through the ball screw mechanism. This changes the magnetic attraction distance between the magnetically controlled resistance adjustment rod 14-1 and the inner magnetic flywheel 1-8, thereby adjusting the magnitude of the motion resistance of the inner magnetic flywheel 1-8 to adapt to the exercise intensity needs of different people. Moreover, the resistance change of the resistance adjustment component 14 is uniform during the adjustment process, making it more convenient for users to adjust according to their own physical condition at any time, thus improving the overall functional flexibility.

[0082] In an optional implementation, the magnetically controlled adjusting rod 14-1 can also be simultaneously configured as a touch-adjusting adjusting rod, used to directly press the inner magnetic flywheel 1-8, thereby adjusting the resistance by coordinating the change of the touch-adjusting friction force based on the magnetic attraction resistance.

[0083] Both the synchronous belt 1-2 and the transmission belt 1-9 can be made of polyurethane, which has high strength and wear resistance, can extend service life, and has high transmission efficiency, reducing power loss. Both the left outer shell 1-6 and the right outer shell 1-12 can be made of ABS plastic, which has good toughness and impact resistance, is lightweight and easy to process and mold, reducing the overall weight of the exercise bike.

[0084] Please continue to refer to this. Figure 3 and Figure 4The lower part of the front armrest fixing tube assembly 2 is fixedly connected to the main body of the reclining vehicle, and the upper part of the front armrest fixing tube assembly 2 is fixedly equipped with an electronic watch 3. The electronic watch 3 is electrically connected to the electronic control module and is used to display exercise data. The electronic watch 3 can monitor and display the user's exercise time, distance, speed, calorie consumption and other data in real time, so that the user can understand the exercise situation in a timely manner and make it easier to formulate and adjust the exercise plan. In addition, the display screen of the electronic watch 3 adopts a high-definition LCD screen, which is clear and easy to read even in low light environment.

[0085] The hand crank assembly 4 is adapted to the upper part of the front armrest fixing tube assembly 2. It can realize the hand cranking action. At the same time, the front armrest fixing tube assembly 2 provides support and rotation axis for the hand crank assembly 4, ensuring that its cranking process is stable and smooth. The hand crank assembly 4 provides users with another way to exercise their upper limbs. Users can choose to hold the handle assembly for coordinated limb exercise or exercise with the hand crank assembly 4 according to their own preferences, which increases the diversity of exercise and improves the overall functionality and practicality.

[0086] The locking knob assembly 5 is screwed onto the hand crank assembly 4 and faces the front armrest fixing tube assembly 2 to realize the controllable locking function of the hand crank assembly 4.

[0087] Please continue to refer to this. Figure 3 and Figure 4 The bottom tube assembly 7 is fixedly mounted on the bottom of the recumbent bike body. The front leg tube assembly 6 and the rear leg tube assembly 8 are respectively fixedly mounted on the front and rear ends of the bottom tube assembly 7, forming a support base for the exercise bike. The bottom of the front leg tube assembly 6 and the rear leg tube assembly 8 are provided with anti-slip pads to increase the friction with the ground, prevent the exercise bike from sliding during use, and improve overall stability. The bottom tube assembly 7 is made of high-strength steel and has sufficient load-bearing capacity to ensure that it can support body weight and the impact force generated during exercise.

[0088] The rear frame assembly 9 is fixedly mounted on the top of the bottom tube assembly 7, serving as the rear support structure of the exercise bike. Connected to the bottom tube assembly 7 and the rear leg tube assembly 8, it provides stable support for the entire exercise bike, ensuring it does not wobble during exercise and improving safety. The seat adjustment rail 10 is fixedly mounted on the top of the rear frame assembly 9. The rear frame assembly 9 and the seat adjustment rail 10 are detachably and fixedly equipped with a left rear frame assembly cover 9-1 and a right rear frame assembly cover 9-2 on both sides. The left and right rear frame assembly covers 9-1 and 9-2 are symmetrically positioned to cover the corresponding structural area of ​​the rear frame assembly 9, reducing the impact of the external environment on the rear frame assembly 9 and extending its service life.

[0089] In one optional implementation, the left rear frame assembly cover 9-1 and the right rear frame assembly cover 9-2 are assembled with the rear frame assembly 9 using a snap-fit ​​connection to facilitate subsequent maintenance and replacement.

[0090] The seat cushion assembly 11 includes a seat cushion fixing tube 11-1, a seat cushion 11-2, and a mesh backrest cushion 11-3. The seat cushion fixing tube 11-1 is slidably connected to the seat cushion front-to-back adjustment track 10 via a bottom slide. The seat cushion front-to-back adjustment track 10 is arranged at an angle so that the entire seat cushion assembly 11 can move along the seat cushion front-to-back adjustment track 10, allowing the user to adjust the height and front-to-back position of the seat cushion 11-2 according to their own height and body shape, thereby obtaining a more comfortable exercise posture.

[0091] Specifically, the seat cushion 11-2 is fixedly connected to the seat back cushion fixing tube 11-1. The seat cushion 11-2 is filled with high-density sponge and covered with breathable fabric, which has good elasticity and breathability, can distribute pressure on the buttocks, and reduce discomfort caused by prolonged sitting. The mesh back cushion 11-3 is fixedly connected to the back side of the seat cushion 11-2. The ergonomic arc design of the mesh back cushion 11-3 conforms to the curve of the human back, and the mesh material has good breathability, which can reduce back sweating, while providing sufficient support to reduce back fatigue. Through the design of the seat back cushion assembly 11, the user's exercise comfort is significantly improved, so that the exercise can be carried out more continuously.

[0092] As another preferred embodiment, the mesh backrest cushion 11-3 may be made of, but is not limited to, nylon material. Nylon material has high strength and elasticity, is not easily deformed, and is wear-resistant, and can withstand the pressure on the user's back. The breathable fabric of the seat cushion 11-2 may be made of, but is not limited to, bamboo fiber material, which has natural antibacterial properties and good moisture absorption, effectively improving the comfort of use.

[0093] The left handle assembly 12 includes a left handle main tube 12-1, a left handle transmission arm 12-2, and a left connecting tube assembly 12-3. The left handle main tube 12-1 is fitted to the horizontal vehicle body at its center, and its bottom end is fixedly connected to one side of the left handle transmission arm 12-2. The end of the left handle main tube 12-1 is provided with a non-slip grip for easy and secure handling. One end of the left connecting tube assembly 12-3 is eccentrically fitted to the first synchronous belt pulley 1-1, and the other end of the left connecting tube assembly 12-3 is connected to the left handle transmission arm 12-2. The other side of 2-2 is connected to the transmission assembly, which is used to enable the power to be further transmitted to the transmission assembly of the horizontal vehicle assembly 1 through the left handle transmission arm 12-2 and the left connecting pipe assembly 12-3 when the user swings the left handle main tube 12-1 back and forth, and to overcome the resistance in sync with the foot to achieve the coordinated exercise function, and / or, when the user steps on the left pedal 15, the left pedal 15 drives the left turntable 1-5, the left pedal bracket 1-4 to transmit power to the second synchronous belt pulley 1-3, and then to the first synchronous belt pulley 1-1, and finally assists the left handle assembly 12 to swing back and forth, thereby further ensuring the overall coordinated exercise function and its application flexibility.

[0094] The right handle assembly 13 is symmetrically arranged with respect to the left handle assembly 12. Specifically, the right handle assembly 13 includes a right handle main tube 13-1, a right handle transmission arm 13-2, and a right connecting tube assembly 13-3. The right handle main tube 13-1 is fitted to the horizontal vehicle body at its middle position, and its bottom end is fixedly connected to one side of the right handle transmission arm 13-2. The end of the right handle main tube 13-1 also has a non-slip grip. One end of the right connecting tube assembly 13-3 is eccentrically fitted to the first synchronous belt pulley 1-1, and the other end of the right connecting tube assembly 13-3 is connected to the right handle transmission arm 13-2. The connection between the other side of the -2 is designed to allow power to be transmitted to the transmission components of the horizontal vehicle assembly 1 via the right handlebar drive arm 13-2 and the right connecting pipe assembly 13-3 when the user swings the right handlebar main tube 13-1 back and forth. This power is then simultaneously linked with the foot to overcome resistance. Alternatively, when the user steps on the right pedal 16, the right pedal 16 drives the right turntable 1-11 and the right pedal bracket 1-10 to transmit power to the second synchronous belt pulley 1-3 and then to the first synchronous belt pulley 1-1. This ultimately assists the right handlebar assembly 13 in swinging back and forth. Thus, by using the overall design of the right handlebar assembly 13 and the left handlebar assembly 12 to synchronize with the foot movement, a coordinated exercise function is achieved, further ensuring the overall application flexibility.

[0095] The length and angle design of the left handle assembly 12 and the right handle assembly 13 are both ergonomic, allowing the user to keep their arms naturally bent when holding the handle, reducing shoulder and arm fatigue.

[0096] This utility model embodiment achieves a combined hand-crank and foot-pedal exercise function through the coordinated operation of various components, and allows switching of exercise modes according to needs, solving the shortcomings of the single-function mode of existing exercise bikes. At the same time, the overall ergonomic architecture design improves user comfort, and the material and structural design of each component takes into account practicality, safety and durability, making this exercise bike have high market application value.

[0097] In actual use, the user first adjusts and fixes the position of the seat cushion 11-2 according to their own situation using the seat cushion front and back adjustment track 10; then the user sits on the seat cushion 11-2 with their back pressed against the mesh backrest cushion 11-3, and places their feet on the left pedal 15 and right pedal 16 respectively. The hands can choose to hold the left handle assembly 12 and right handle assembly 13, or choose to hold the hand crank assembly 4, depending on the training mode requirements, and then exercise by pedaling with the feet and cranking with the hands; in addition, the resistance can be adjusted through the resistance adjustment assembly 14 to further meet the training needs of different human conditions and improve adaptability and flexibility.
