Detailed ways

The present invention will be described in detail and concretely below through specific embodiments, so as to better understand the present invention, but the following embodiments do not limit the protection scope of the present invention.

Example 1

The present embodiment discloses a three-position power storage and power generation mechanism for a fitness machine, including an assembly base plate 1 , a power storage spring storage mechanism 2 , a generator 3 and a self-comparison transmission assembly 4 .

The power storage clockwork storage mechanism 2 stores the work of the fitness machine and transmits the energy to the generator 4 through the self-comparison transmission assembly 3. The number of the power storage clockwork storage mechanism 2 is three, and the self-comparison transmission assembly 4 automatically compares the three storage mechanisms. The power spring stores the energy in the mechanism 2 and transmits the energy of the highest energy among them to the generator 3 .

The generator 3 is arranged at the center 1 of the bottom plate of the general assembly, and the three power storage spring storage mechanisms 2 are arranged in a circular array with the generator 3 as the center.

Each power accumulating spring storage mechanism 2 includes: a power accumulating assembly 21 , a pulling rope collector 22 , a pulling rope 23 and a mainspring central shaft 24 . The mainspring central shaft 24 passes through the assembly base plate 1 and is connected to the assembly base plate 1 through the mainspring central shaft fixing bearing 241 . The force accumulating component 21 and the pulling rope collector 23 are both arranged on the central shaft 24 of the mainspring, and are respectively arranged on both sides of the assembly bottom plate 1 . The power accumulating assembly 21 is sequentially provided with: a power accumulating mainspring clamping plate 211 , a power accumulating mainspring external gear 212 , a power accumulating mainspring 213 and a power accumulating mainspring one-way bearing 214 from the direction close to the general assembly base plate 1 to the direction away from the general assembly base plate 1 . . The power accumulating mainspring external gear 212 keeps synchronously rotating with the power accumulating mainspring locking plate 211 . The pull 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 is connected to the return spring 223. The mainspring 222 keeps rotating synchronously, and the pulling rope 23 is wound on the drum 221 .

The three accumulating spring one-way bearings 214 are provided with an accumulating spring one-way bearing seat 25, and the returning spring 222 is provided with a returning spring seat 26, which is fixedly connected with the assembly bottom plate 1 .

The self-comparison transmission assembly 4 includes a secondary gear 41 , a secondary gear shaft 42 , a secondary gear one-way bearing 43 , a rotation stop block 44 , a rotation stop block cover plate 45 , a drive gear 46 and a sun gear 47 . The sun gear 47 is fixedly connected to the generator shaft of the generator 3 . The number of auxiliary gears 41 is three, which are respectively meshed with the external gear 212 of the power storage spring, and are transmitted to the driving gear 46 on the other side of the assembly base plate 1 through the auxiliary gear shaft 42 . The driving gear 46 meshes with the central gear 47 . The top of the auxiliary gear 41 is provided with an upper bearing seat 48 .

The assembly bottom plate 1 is provided with a splint 11 , the anti-rotation block 44 slides between the splints 11 , the anti-rotation block 44 is provided with a clamping part 441 , and the power storage spring clamping plate 211 is provided with a gap for clamping the clamping part 441 215.

The ends of the splint 11 are all close to the center of the assembly bottom plate 1 . The anti-rotation block 44 forms a friction pair with the power-storage spring locking plate 211 , and the power-storage spring locking plate 211 presses the anti-rotation block 44 to the center position of the assembly bottom plate 1 . Under this action, the three anti-rotation blocks 44 are pressed against each other, and the other two anti-rotation blocks 44 are locked in the corresponding inside the gap 215.

The bearings used in this embodiment are all one-way bearings, which can cause the transmission mechanism to rotate when people exercise and do reciprocating motion. When in use, people pull the pull rope 23 and transfer the energy into the power storage spring 213 . When the energy in the power storage spring 213 is weak, the power storage spring 213 is not enough to drive the power storage spring locking plate 211 to push the anti-rotation block 44 away, so the anti-rotation block 44 is clamped in the gap 215, and the process continues. Charge up. When the energy of the accumulating spring 213 exceeds the energy of the other two accumulating springs, it will push the anti-rotation block 44 to move toward the center of the assembly bottom plate 6 to cancel the blocking of the accumulating spring by the anti-rotating block 44 211 constraints.

The working principle of the self-comparison transmission assembly 4 is described below: As shown in the figure, the three force accumulating spring clips 211 all store forces of different magnitudes, and all tend to squeeze the anti-rotation block 44 to the center position. When one of the power storage spring locking plates 211 is larger than the other two power storage spring locking plates 211 (the power storage spring locking plate at the lower right position in the figure), the corresponding anti-rotation block 44 is oriented toward the center. move, and press the other two anti-rotation blocks 44 (corresponding to the upper and lower left anti-rotation blocks 44 in the figure) in the gap 215, so that the power storage spring clip plate 211 is in a state of continuous power storage, while the lower right The power accumulating spring clip plate 211 releases energy and transmits the energy to the generator through the auxiliary gear 41 , the driving gear 46 and the central gear 47 . When the lower right power accumulating spring clip plate 211 rotates once and the notch 215 rotates to the anti-rotation block 44, the anti-rotation block 44 loses its support and is squeezed into the gap 215 by the other upper and lower left anti-rotation blocks 44. And the anti-rotation blocks 44 at the upper and lower left positions are automatically compared according to the size of the stored power in its own power storage spring 213, and the one with the larger power storage spring 213 drives the power storage spring clip plate 211 to remove it. The corresponding anti-rotation block 44 is extruded toward the center and enters the next cycle. When the device stops being used, the return spring 222 rotates the notch 215 to the position corresponding to the anti-rotation block 44 so that the device can continue to be used next time.

This embodiment can simultaneously satisfy 1-3 groups of fitness machines doing work and generating electricity at the same time. The power generation device can be integrated, the space and volume of the power generation device can be reduced, and the manufacturing cost can be saved. At the same time, due to the self-comparative transmission component, the rotation speed of the generator can be stabilized to achieve the purpose of stable power generation.
