Specific implementation method

[0020] The present invention will be introduced in detail and specifically through specific embodiments to better understand the present invention. However, the following embodiments do not limit the protection scope of the present invention.

[0021] Embodiment 1 This embodiment discloses a three - position energy - storing power - generating mechanism of a fitness device, including a general assembly bottom plate 1, an energy - storing spring storage mechanism 2, a generator 3 and a self - comparing transmission component 4.

[0022] The energy storage spring storage mechanism 2 stores the work done by the fitness device and conveys the energy to the generator 3 through the self-comparing transmission component 4. The number of energy storage spring storage mechanisms 2 is three. The self-comparing transmission component 4 automatically compares the energy in the three energy storage spring storage mechanisms 2 and conveys the energy of the one with the highest energy to the generator 3.

[0023] The generator 3 is arranged at the center 1 position of the general assembly bottom plate. The three energy storage spring storage mechanisms 2 are arranged in a circular array with the generator 3 as the center. Each energy storage spring storage mechanism 2 includes: an energy storage component 21, a rope collector 22, a rope 23 and a spring central shaft 24. The spring central shaft 24 is penetrated through the general assembly bottom plate 1 and is connected to the general assembly bottom plate 1 through a spring central shaft fixing bearing 241.

[0024] The energy storage component 21 and the rope collector 22 are both arranged on the spring central shaft 24 and are respectively arranged on both sides of the general assembly bottom plate 1. The energy storage component 21 is successively provided with: an energy storage spring clamping plate 211, an energy storage spring external gear 212, an energy storage spring 213 and an energy storage spring one-way bearing 214 from the side close to the general assembly bottom plate 1 to the side far from the general assembly bottom plate 1. The energy storage spring external gear 212 rotates synchronously with the energy storage spring clamping plate 211. The rope collector 22 includes a reel 221, a return spring 222 and a collector one-way bearing 223. The collector one-way bearing 223 and the return spring 222 are arranged at the end of the spring central shaft 24. The reel 221 rotates synchronously with the return spring 222. The rope 23 is wound on the reel 221.

[0025] Energy storage spring one-way bearing seats 25 are arranged on the three energy storage spring one-way bearings 214. A return spring seat 26 is arranged on the return spring 222. The return spring seat 26 is fixedly connected to the general assembly bottom plate 1.

[0026] The self-comparing transmission component 4 includes a sub-gear 41, a sub-gear shaft 42, a sub-gear one-way bearing 43, a stop block 44, a stop block cover plate 45, a driving gear 46 and a central gear 47. The central gear 47 is fixedly connected to the generator shaft of the generator 3. The number of sub-gears 41 is three, which are respectively meshed with the energy storage spring external gears 212 and are transmitted to the driving gear 46 on the other side of the general assembly bottom plate 1 through the sub-gear shaft 42. The driving gear 46 is meshed with the central gear 47. An upper bearing seat 48 is arranged on the top of the sub-gear 41.

[0027] A clamping plate 11 is arranged on the general assembly bottom plate 1. The stop block 44 slides between the clamping plates 11. A clamping portion 441 is arranged on the stop block 44. A notch 215 for clamping the clamping portion 441 is arranged on the energy storage spring clamping plate 211.

[0028] The ends of the clamping plates 11 are all close to the central position of the general assembly base plate 1. The anti-rotation block 44 and the energy storage spring clamping plate 211 form a friction pair, and the energy storage spring clamping plate 211 squeezes the anti-rotation block 44 towards the central position of the general assembly base plate 1. Under this action, the three anti-rotation blocks 44 squeeze each other, and when one anti-rotation block 44 moves relative to the outer ring of the energy storage spring clamping plate 211, the other two anti-rotation blocks 44 are clamped in the corresponding notches 215.

[0029] In this embodiment, the bearings used are all one-way bearings. When people do reciprocating exercises, the transmission mechanism rotates. During use, people pull the pull rope 23 and transfer the energy into the energy storage spring 213. When the energy in the energy storage spring 213 is weak, the energy storage spring 213 is not enough to drive the energy storage spring clamping plate 211 to push the anti-rotation block 44 away. Therefore, the anti-rotation block 44 is clamped in the notch 215 and continues to store energy. When the energy stored in the energy storage spring 213 exceeds the energy of the other two energy storage springs, it will push the anti-rotation block 44 towards the center of the general assembly base plate 6 to cancel the constraint of the anti-rotation block 44 on the energy storage spring clamping plate 211.

[0030] The working principle of the self-comparing transmission component 4 is introduced as follows: As shown in the figure, different amounts of force are stored in the three energy storage spring clamping plates 211, and they all tend to squeeze the anti-rotation block 44 towards the central position. When one energy storage spring clamping plate 211 is greater than the other two energy storage spring clamping plates 211 (such as the energy storage spring clamping plate at the lower right position in the figure), its corresponding anti-rotation block 44 moves towards the center and presses the other two anti-rotation blocks 44 (the anti-rotation blocks 44 corresponding to the upper and lower left positions in the figure) in the notch 215, so that the energy storage spring clamping plate 211 is in a state of continuing to store energy, while the energy storage spring clamping plate 211 at the lower right releases energy and transmits the energy to the generator through the secondary gear 41, the driving gear 46 and the central gear 47. When the energy storage spring clamping plate 211 at the lower right rotates one week and the notch 215 rotates to the position of the anti-rotation block 44, the anti-rotation block 44 loses support and is squeezed into the notch 215 by the other upper and lower left anti-rotation blocks 44. The upper and lower left anti-rotation blocks 44 automatically compare according to the amount of energy stored in their own energy storage springs 213. The energy storage spring 213 with a larger amount of stored energy drives the energy storage spring clamping plate 211 to squeeze its corresponding anti-rotation block 44 towards the center and enters the next cycle. After the device stops being used, the return spring 222 rotates the notch 215 to the position corresponding to the anti-rotation block 44 for the next use of the device.

[0031] This embodiment can simultaneously satisfy the power generation of 1 - 3 groups of fitness machines working at the same time. The power generation devices can be integrated to reduce the space and volume of the power generation devices and save the manufacturing cost. At the same time, since the self-comparing transmission component can stabilize the rotation speed of the generator to achieve the purpose of stable power generation.

For those skilled in the art, any equivalent modifications and substitutions made to the present invention are also within the scope of the present invention. Therefore, all equivalent transformations and modifications made without departing from the spirit and scope of the present invention should be covered within the scope of the present invention.
