Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, and in particular relates to a self-generating stretching machine. Background Technology

[0002] Chinese utility model patent CN201520453878.0 discloses a multifunctional fitness device, including a riding machine with a damping riding device. The damping riding device includes a damper (6) and foot pedals (5) connected to the damper (6). The riding machine includes a main frame (7), which includes a front support (702) and a rear support (701). The damper (6) is fixed on the front support (702). The riding machine also includes foot pedals (3), which are rotatably connected to the main frame (7). This utility model combines the functions of a riding machine and an exercise bike. It has a compact structure and small size, which can promote cardiovascular exercise, accelerate metabolism, and enhance heart and lung function, thereby improving physical fitness. With the development of fitness equipment, more and more fitness equipment has intelligent functions. These intelligent devices consume little power, and most fitness equipment uses charging or batteries to power these intelligent devices.

[0003] This has resulted in existing fitness equipment becoming overly reliant on fixed power sources or unable to perform its smart functions without batteries. Summary of the Invention

[0004] The purpose of this utility model embodiment is to provide a self-generating stretching machine, which aims to solve the technical problem that in the existing technology, more and more fitness equipment has intelligent functions. These intelligent devices do not consume much power, and most fitness equipment uses charging or batteries to power these intelligent devices. This causes existing fitness equipment to be overly dependent on fixed power sources or unable to realize its intelligent functions without batteries.

[0005] The present invention is implemented as follows:

[0006] A self-generating extension machine includes an extension assembly. The extension assembly includes a front support rod and a rear support rod fixed together in an X-shape. A seat support rod and an armrest swing rod are sequentially hinged to the front end of the rear support rod. The seat support rod and the armrest swing rod are hinged together at the bottom via a connecting rod. A foot wheel is provided at the bottom end of the front support rod, and a generator is provided at the rear support rod. The foot wheel and the generator are connected by a belt to drive the generator to generate electricity. The generator is connected to the end of the seat support rod via a pull rope. The movement of the seat support rod drives the generator to generate electricity. The generator is connected to the intelligent component of the extension machine to provide power to the intelligent component.

[0007] Furthermore, the generator is connected to a lithium battery, which is fixed to the bottom of the rear support rod. The lithium battery is connected to the smart component to supply power to the smart component.

[0008] Furthermore, the generator's rotating wheel is connected to a pull rope, which passes around a pulley fixed to the bottom of the rear support rod and connects to the end of the seat support rod.

[0009] Furthermore, a seat is fixed to the top surface of the end of the seat support rod.

[0010] Furthermore, the rear support rod has a front fixing seat at its top end, and a handrail swing arm is hinged to the front fixing seat via a front hinge shaft. The top of the handrail swing arm has a handrail, which is elliptical in shape. A central fixing seat is located in the middle of the handrail. A smart component is fixed inside the central fixing seat. The surface of the central fixing seat has buttons, a speedometer, and a mobile phone charging interface.

[0011] Furthermore, the handrail swing arm includes an outer tube and an inner tube inserted inside the outer tube, with the top of the inner tube fixedly connected to the handrail; the outer tube is hinged to the front fixed seat via a hinge shaft; the bottom of the outer tube is provided with a bent end, and the fully extended end is connected to a gas spring fixed in the middle of the front support rod via a steel wire rope, the gas spring providing damping force to the handrail swing arm and resetting the handrail swing arm.

[0012] The positive effects of this invention are as follows: When the user performs stretching exercises using the stretching component, the seat support rod rotates around the hinge point, which in turn drives the generator to rotate via the pull rope, generating electricity. Simultaneously, the user can drive the pedal wheel to rotate while stretching or independently via foot pedal. Since the pedal wheel and generator are connected by a belt, the rotation of the pedal wheel drives the generator to rotate, thus generating electricity. This invention enables the user's movement to drive the generator to generate electricity, and the generator is connected to the intelligent components of the stretching machine to provide power to the intelligent components, achieving self-sufficiency in electricity for the stretching machine.
