One end of the transmission rod 240 is connected to the sun gear 232, the other end of the transmission rod 240 is connected to the input shaft of the generator 210, the rotation of the sun gear 232 can drive the transmission rod 240 to rotate around the axis of the transmission rod, and the rotation of the transmission rod 240 around the axis of the transmission rod can drive the input shaft to rotate, so that the generator 210 can generate electric energy. Alternatively, the transmission rod 240 and the sun gear 232 may be integrally formed, or the transmission rod 240 and the sun gear 232 may be connected by bonding or welding. Alternatively, the transmission rod 240 and the input shaft of the generator 210 may be coupled by a coupling.

When the battery 700 needs to be charged, a user moves the operating rod 100, the operating rod 100 drives the connecting rod 220 to move, the connecting rod 220 drives the planet wheel 233 to rotate around the sun wheel 232, the planet wheel 233 rotates to drive the sun wheel 232 to rotate around the axis of the planet wheel 233, the sun wheel 232 rotates to drive the transmission rod 240 to rotate, and the transmission rod 240 rotates to drive the input shaft to rotate, so that the generator 210 generates electric energy.

The linear speeds of the planet wheels 233 and the sun wheel 232 are the same, but the diameter of the planet wheels 233 is larger than that of the sun wheel 232, so that the rotating speed of the sun wheel 232 is larger, the rotating speeds of the sun wheel 232 and the transmission rod 240 are the same, and the rotating speed of the transmission rod 240 is further improved. In this case, the rotation speed of the input shaft of the generator 210 is increased, and the power generation efficiency of the generator 210 is further improved.

To prevent the deflection of the connecting rod 220 during the movement, the power generation assembly may further include a first guide 250, and the first guide 250 is slidably coupled to the connecting rod 220 in the movement direction of the connecting rod 220. In this case, the first guide 250 can restrict the moving direction of the link 220, thereby preventing the link 220 from being deviated during the movement, promoting higher moving accuracy of the link 220, and further improving reliability of the power generation module.

Under the condition that the positioning protrusion 271 is inserted into the first positioning space, the positioning protrusion 271 is in positioning fit with the first positioning space, which indicates that the first guide 250 is located at the predetermined installation position.

In order to improve the assembly stability of the connecting rod 220, in the embodiment disclosed in the present application, the power generation assembly may further include a limit assembly 260, and the limit assembly 260 is in limit fit with the connecting rod 220 in the axial extending direction of the gear ring 231. Alternatively, the axial extension direction of the ring gear 231 is perpendicular to the moving direction of the link 220.

In addition, the connecting rod 220 cannot move in the axial extension direction of the gear ring 231, and then the planet wheel 233 cannot move in the extension direction of the gear ring 231, so that the problem that the planet wheel 233 moves to cause the meshing of the planet wheel 233, the gear ring 231 and the sun wheel 232 to be staggered, which causes the gear mechanism 230 not to smoothly perform motion transmission, further enhances the assembly stability of the gear mechanism, and improves the reliability of the power generation assembly.

In an alternative embodiment, the power generation assembly may include an electromagnetic coil 310 and a first permanent magnet 410, the first permanent magnet 410 being provided to the lever 100. Alternatively, the first permanent magnet 410 may be adhesively fixed to the lever 100.

The electromagnetic coil 310 is disposed in the device housing 800, and the electromagnetic coil 310 is electrically connected to the battery 700, so as to supply power to the battery 700 through the electromagnetic coil 310.

During the reciprocating movement of the operating rod 100 between the first position and the second position, the first permanent magnet 410 makes a cutting magnetic induction line movement relative to the electromagnetic coil 310, so that the magnetic flux passing through the closed electromagnetic coil 310 changes, and further an induced current is generated in the electromagnetic coil 310, and the electromagnetic coil 310 is connected with a battery 700 of the electronic device, thereby realizing the power supply of the battery 700 through the electromagnetic coil 310.

To facilitate the installation of the electromagnetic coil 310, the power generation assembly may further include a mounting base 320, the electromagnetic coil 310 being wound around the mounting base 320.

In the embodiment disclosed in the present application, the power generation assembly may include both the generator 210 and the electromagnetic coil 310, and the generator 210 and the electromagnetic coil 310 are electrically connected to the battery 700 at the same time, so that the charging efficiency of the battery 700 can be improved.

For example, the magnetic pole of the first permanent magnet 410 facing the second permanent magnet 420 may be an S-pole, and the magnetic pole of the second permanent magnet 420 facing the first permanent magnet 410 is an N-pole. In this case, the first permanent magnet 410 and the second permanent magnet 420 have opposite poles attracted to each other, and the connection strength between the first permanent magnet 410 and the operating lever 100 and the second permanent magnet 420 can be enhanced.

In addition, the second permanent magnet 420 is additionally arranged, so that induced current generated by the electromagnetic coil 310 in the moving process of the operating rod 100 can be increased, and the power generation efficiency is improved.

In the above-mentioned solution, the first permanent magnet 410 is disposed on the operation rod 100 and moves along with the operation rod 100, and in order to prevent the first permanent magnet 410 from colliding with other parts when the operation rod 100 moves to the limit position, the operation rod 100 may be provided with the first receiving groove 110, and the first permanent magnet 410 is disposed in the first receiving groove 110. In this case, the first receiving groove 110 can protect the first permanent magnet 410, and prevent the first permanent magnet 410 from colliding with other parts and being damaged during the movement of the operation lever 100.

In addition, the first permanent magnet 410 is disposed in the first accommodating groove 110, so that the volume of the power generating assembly can be reduced, and the trend of light and thin electronic devices is met.

The number of the first receiving grooves 110 is the same as that of the permanent magnets, and the first receiving grooves 110 are disposed in a one-to-one correspondence manner, for example, when the power generation assembly includes the first permanent magnet 410 and the second permanent magnet 420, the operating rod 100 has two first receiving grooves 110, the two first receiving grooves 110 are located on two opposite side surfaces of the operating rod 100, and the first permanent magnet 410 and the second permanent magnet 420 are respectively disposed in the two first receiving grooves 110.

In order to better protect the electromagnetic coil 310, the power generation assembly may further include a housing 610, the electromagnetic coil 310 is disposed in the housing 610, a portion of the lever 100 is located in the housing 610, a portion of the lever 100 extends out of the housing 610, and the first permanent magnet 410 is disposed on the portion of the lever 100 located in the housing 610.

In order to facilitate the maintenance and disassembly of the electromagnetic coil 310, the housing 610 may have a second opening 613, the electromagnetic coil 310 may be installed and maintained through the second opening 613, the power generation assembly may further include a cover 620, the cover 620 may be detachably connected to the housing 610 through a connector 630, and the cover 620 blocks the second opening 613 to protect the electromagnetic coil 310 in the housing 610. Alternatively, the connecting member 630 may be a screw.

In an alternative embodiment, the power generation assembly may include a first piezoelectric element 510, the first piezoelectric element 510 is located at one side of the operation rod 100 in the moving direction of the operation rod 100, and the first piezoelectric element 510 is deformed to generate current in the first piezoelectric element 510 when the operation rod 100 moves toward the first piezoelectric element 510. The first piezoelectric element 510 is disposed in the device housing 800, and the first piezoelectric element 510 is electrically connected to the battery 700 to supply power to the battery 700. Alternatively, the first piezoelectric element 510 may be a piezoelectric sheet. The number of the first piezoelectric members 510 may be one or more, and in the case where the number of the first piezoelectric members 510 is plural, a plurality of the first piezoelectric members 510 are stacked and connected, and each of the first piezoelectric members 510 may be electrically connected to the battery 700, so as to increase the power generation amount of the power generation module.

In the embodiment of the present application, the operation rod 100 is matched with the first piezoelectric element 510, and the first piezoelectric element 510 is deformed by moving the operation rod 100, so that the first piezoelectric element 510 generates current, and the first piezoelectric element 510 is electrically connected to the battery 700, so as to supply power to the battery 700 through the first piezoelectric element 510.

There are various ways in which the lever 100 cooperates with the first piezoelectric element 510 to deform the first piezoelectric element 510, for example, when the lever 100 moves to an extreme position, i.e., the first position or the second position, the lever 100 may directly contact the first piezoelectric element 510 and press the first piezoelectric element 510, thereby deforming the first piezoelectric element 510. However, the above manner causes frequent collision between the operation lever 100 and the first piezoelectric element 510, which easily causes damage to the operation lever 100, and vibration and noise may be generated during collision between the operation lever 100 and the first piezoelectric element 510, which may cause poor user experience.

In order to solve the above problem, the power generation assembly may further include a first permanent magnet 410 and a third permanent magnet 430, the first permanent magnet 410 is disposed on the operating rod 100, optionally, the first permanent magnet 410 may be fixed to the operating rod 100 by adhesion, the third permanent magnet 430 is disposed on the first piezoelectric element 510, optionally, the third permanent magnet 430 may be fixed to the first piezoelectric element 510 by adhesion, the third permanent magnet 430 is disposed on the first piezoelectric element 510 close to the operating rod 100, and a magnetic pole of the first permanent magnet 410 facing the third permanent magnet 430 is the same as a magnetic pole of the third permanent magnet 430 facing the first permanent magnet 410. For example, in the case where the magnetic pole of the first permanent magnet 410 facing the third permanent magnet 430 is the S pole, the magnetic pole of the third permanent magnet 430 facing the first permanent magnet 410 is also the S pole.

In this case, when the operation rod 100 is close to the first piezoelectric element 510, the same poles of the first permanent magnet 410 and the third permanent magnet 430 repel each other, so as to generate a repulsive force, and the repulsive force causes the first piezoelectric element 510 to deform under a force to generate a current, thereby preventing the operation rod 100 from colliding with the first piezoelectric element 510, reducing vibration and noise generated by the direct collision between the operation rod 100 and the first piezoelectric element 510, and improving the use experience of a user. Meanwhile, the repulsive force generated by the first permanent magnet 410 and the third permanent magnet 430 can also reduce the impact force applied to the operation rod 100 during the moving process, and prolong the service life of the operation rod 100.

In order to reduce the volume of the power generation assembly, the operation rod 100 is provided with a first receiving groove 110, the first permanent magnet 410 is disposed in the first receiving groove 110, the power generation assembly further includes a housing 610, the housing 610 is disposed in the device housing 800 and located in the inner cavity, a second receiving groove 611 is disposed on a side wall of the housing 610, and the first piezoelectric element 510 and the third permanent magnet 430 are disposed in the second receiving groove 611. In this case, the first permanent magnet 410 is disposed in the first receiving groove 110, and the third permanent magnet 430 is disposed in the second receiving groove 611, so that the volume of the power generating assembly can be reduced, and the development trend of lightening and thinning of electronic devices is met.

Alternatively, the connecting member 630 may be a screw.

The operating rod 100 is disposed in the casing 610, a portion of the operating rod 100 is located in the casing 610, the first permanent magnet 410 is disposed on the portion of the operating rod 100 located in the casing 610, and the portion of the operating rod 100 extends out of the casing 610, so that a user can operate the operating rod 100 conveniently.

In a further technical solution, the power generation assembly may further include a second piezoelectric element 520, the second piezoelectric element 520 is engaged with the operating rod 100, and in a moving direction of the operating rod 100, the first piezoelectric element 510 and the second piezoelectric element 520 are respectively located at two sides of the operating rod 100, and in a case that the operating rod 100 moves towards the direction of the second piezoelectric element 520, the second piezoelectric element 520 deforms, so that the second piezoelectric element 520 generates a current, and the second piezoelectric element 520 is electrically connected to the battery 700 to supply power to the battery 700. In this case, the first piezoelectric element 510 and the second piezoelectric element 520 can both generate current, thereby improving the power generation efficiency.

Of course, the number of the second piezoelectric elements 520 may be one or more, and in the case where the number of the second piezoelectric elements 520 is plural, a plurality of the second piezoelectric elements 520 are stacked and connected, and each of the second piezoelectric elements 520 is electrically connected to the battery 700, thereby further improving the power generation amount.

Under the condition that the power generation assembly has the first piezoelectric element 510 and the second piezoelectric element 520 at the same time, the power generation assembly may further include a second permanent magnet 420 and a fourth permanent magnet 440, the second permanent magnet 420 is disposed on the operating rod 100, the second permanent magnet 420 and the first permanent magnet 410 are respectively disposed on two sides of the operating rod 100, which are away from each other, the fourth permanent magnet 440 is disposed on the second piezoelectric element 520, the fourth permanent magnet 440 is located on one side of the second piezoelectric element 520 close to the operating rod 100, and a magnetic pole of the second permanent magnet 420 facing the fourth permanent magnet 440 is the same as a magnetic pole of the fourth permanent magnet 440 facing the second permanent magnet 420. For example, the magnetic pole of the second permanent magnet 420 facing the fourth permanent magnet 440 may be an N-pole, and the magnetic pole of the fourth permanent magnet 440 facing the second permanent magnet 420 is also an N-pole.

Similarly, when the operation rod 100 is close to the second piezoelectric element 520, the like poles of the second permanent magnet 420 and the fourth permanent magnet 440 repel each other, so as to generate a repulsive force, the repulsive force makes the second piezoelectric element 520 deformed by a force to generate a current, and the repulsive force can also reduce the impact force on the operation rod 100 during the moving process, thereby protecting the operation rod 100.

In this case, the second guide structure 612 can limit the moving direction of the operation lever 100, thereby preventing the operation lever 100 from being deviated during the moving process, promoting the moving accuracy of the operation lever 100 to be high, and further improving the reliability of the power generation module.

Specifically, the energy management circuit may include a three-input Buck converter (ac/dc conversion module), a rectifying and voltage-stabilizing module, a path management module, a sampling circuit module, a driving circuit module, a battery monitoring and protecting module, a digital control circuit module, and the like.

The path management module is primarily used to determine the way to power the battery 700. In this case, the power generation assembly may also directly supply power to electronic devices other than the battery 700.
