However, most existing hand-cranked generators require both hands to operate, are gear-driven, and are noisy and prone to wear and tear. Utility Model Content
[0003] This application provides a push-to-power generation device to solve the problems existing in related technologies. The technical solution is as follows:
[0004] This application provides a push-to-power generator, including:
[0005] The outer casing has a receiving cavity inside;
[0006] A control component is mounted on the housing, with a portion of the control component located within the accommodating cavity.
[0007] A rotating component is housed within the housing; the control component pre-starts the rotating component and then shuts it down.
[0008] A sliding component is disposed inside the housing, and its sliding direction is the axial direction of the rotating component;
[0009] A permanent magnet is mounted on a sliding assembly.
[0010] The flywheel permanent magnet is located inside the housing. When the control component is turned off, pressing the sliding component causes the bracket permanent magnet and the flywheel permanent magnet to alternately generate thrust and attraction, driving the rotating component to rotate, thereby generating electricity from the brushless motor.

[0018] The protrusion is set on the bracket and is located in the wave groove. When the flywheel shaft rotates, the bracket reciprocates inside the housing.
[0019] The large button is located on the housing. When the control components are off, the flywheel shaft rotates due to inertia. Pressing down the large button causes the bracket to reciprocate, which causes the permanent magnets of the bracket and the flywheel to alternately generate thrust and attraction, driving the flywheel to rotate, thereby generating electricity from the brushless motor.
[0020] In one implementation, it further includes:
[0021] The guide post is located inside the housing and passes through the bracket.
[0022] In one implementation,

[0034] The storage battery is housed inside the casing and is electrically connected to the control board.
[0035] The start button is located on the housing and is electrically connected to the control board. The start button controls the opening of the flywheel and energizes the stator windings of the brushless motor, driving the flywheel to rotate.
[0036] In one implementation,
[0037] The USB port is located on the casing.
[0038] In one implementation, it further includes:
[0039] The hanging rope is attached to the outer casing.
[0040] The advantages or beneficial effects of the above technical solutions include at least the following:
[0041] The sliding component is set to a press-type mechanism. The rotating component is pre-rotated by the control component. After three seconds, the control component is turned off. The rotating component continues to rotate under inertia. Pressing the sliding component causes it to reciprocate within the housing. The permanent magnets of the bracket and the permanent magnets of the flywheel alternately generate thrust and attraction, driving the flywheel to rotate, thereby generating electricity from the brushless motor. Compared with existing hand-cranked generators, it is easier to hold and operate with one hand, and it has less noise because it is not driven by gears.

[0053] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0054] Figures 1-3 This diagram illustrates a structural diagram of a push-button power generation device according to an embodiment of this application. Figures 1-3 As shown, the power generation device may include:
[0055] The outer casing 100 has a receiving cavity inside;
[0056] Control component 200 is disposed on housing 100, and a portion of control component 200 is located within receiving cavity;
[0057] Rotating component 400 is disposed inside housing 100, and control component 200 pre-starts rotating component 400 and then shuts it off;
[0058] The sliding component 300 is disposed inside the housing 100, and its sliding direction is the axial direction of the rotating component 400;
[0059] The permanent magnet 330 is mounted on the sliding assembly 300.
[0060] The flywheel 430 permanent magnet is installed inside the housing 100. When the control component 200 is closed, the sliding component 300 is pressed so that the support permanent magnet 330 and the flywheel 430 permanent magnet alternately generate thrust and attraction, driving the rotating component 400 to rotate, thereby generating electricity from the brushless motor.
[0061] In this embodiment, the control component 200 initiates the pre-rotation of the rotating component 400. After three seconds, the control component 200 is deactivated, and the rotating component 400 continues to rotate due to inertia. Pressing the sliding component 300 causes it to reciprocate within the housing 100, resulting in alternating thrust and attraction between the permanent magnets of the support frame 330 and the flywheel 430, driving the flywheel 430 to rotate, thereby generating electricity from the brushless motor. Compared to existing hand-cranked generators, this design is easier to hold and operate with one hand, and it produces less noise as it is not driven by gears.
[0062] In one implementation,
[0063] Rotating assembly 400 includes:
[0064] Flywheel 430, control component 200 controls the start of flywheel 430;
[0065] The flywheel shaft 432 is driven to rotate by the flywheel 430, and the flywheel shaft 432 has a wave groove 431.
[0066] In this embodiment, the flywheel 430 (i.e., the brushless motor rotor) is started to rotate by the control component 200, which drives the flywheel shaft core 432 to rotate.
[0067] In one implementation,
[0068] The sliding component 300 includes:
[0069] The bracket 310 is mounted on the outer casing 100 and is located within the receiving cavity;
[0070] The protrusion 320 is set on the bracket 310 and is located in the wave groove 431. When the flywheel shaft core 432 rotates, the bracket 310 reciprocates within the housing 100.
[0071] The large button 340 is located on the housing 100. When the control component 200 is closed, the flywheel shaft core 432 rotates due to inertia, pressing down the large button 340, which causes the bracket 310 to reciprocate, so that the permanent magnet 330 of the bracket and the permanent magnet of the flywheel 430 alternately generate thrust and attraction, driving the flywheel 430 to rotate, thereby generating electricity from the brushless motor.
[0072] In this embodiment, the control component 200 starts the flywheel 430 to rotate, driving the flywheel shaft 432 to rotate. The wave groove 431 on the edge of the flywheel shaft 432 guides the bracket 310 to move up and down. At the same time, the bracket permanent magnet 330 on the bracket 310 and the flywheel 430 permanent magnet alternately generate thrust and attraction, assisting the flywheel 430 (brushless motor rotor) to rotate. Three seconds later, the control component 200 turns off the power to the flywheel 430 (brushless motor rotor), and at the same time, the large button 340 is pressed firmly. Although the flywheel shaft 432 loses power, it continues to rotate at high speed due to its own inertia, causing the bracket 310 and the large button 340 to continue to move up and down.
[0073] Pressing the large button 340 repeatedly will cause the bracket 310 to maintain up-and-down reciprocating motion due to inertia and the deceleration and torque increase effect of the flywheel shaft core 432. This will cause the permanent magnet 330 of the bracket and the permanent magnet of the flywheel 430 to alternately generate thrust and attraction, driving the flywheel 430 (the rotor of the brushless motor) to rotate, thereby generating electricity from the brushless motor.
[0074] At this time, the flywheel 430 (brushless motor rotor) changes from electric drive to finger pressure drive, and the bracket 310 maintains up and down reciprocating motion, so that the permanent magnet 330 of the bracket and the permanent magnet of the flywheel 430 alternately generate thrust and attraction, driving the flywheel 430 (brushless motor rotor) to rotate, thereby generating electricity from the brushless motor.
[0075] Specifically, a brushless motor rotor permanent magnet 440 is provided on the inner bottom of the flywheel 430, and its position corresponds to the brushless motor stator winding 250. The rotation of the brushless motor rotor permanent magnet 440 induces alternating current in the brushless motor stator winding 250.
[0076] Specifically, the permanent magnet 330 is arranged in a ring around the support 310, and the permanent magnet 330 has alternating N and S poles.
[0077] In one implementation, it further includes:
[0078] Guide post 510 is set on the upper cover 500 of the movement and passes through bracket 310.
[0079] In one implementation,
[0080] The Flywheel 430 permanent magnet includes:
[0081] The first magnetic ring 410 has N poles and S poles spaced apart.
[0082] The second magnetic ring 420 is disposed on the flywheel 430 and located inside the accommodating cavity. The first magnetic ring 410 is located above the second magnetic ring 420. The second magnetic ring 420 has N poles and S poles spaced apart, and the N pole of the second magnetic ring 420 corresponds to the S pole of the first magnetic ring 410.
[0083] In this embodiment, the first magnetic ring 410 and the second magnetic ring 420 are each provided with N poles and S poles at intervals, and there is a certain interval between each magnetic pole. The first magnetic ring 410 and the second magnetic ring 420 are stacked, and the N poles and S poles of the first magnetic ring 410 and the second magnetic ring 420 are stacked. Through the arrangement of the magnetic poles of the first magnetic ring 410 and the second magnetic ring 420, it is ensured that when the support 310 reciprocates, the permanent magnet 330 of the support and the first magnetic ring 410 and the second magnetic ring 420 alternately generate thrust and attraction, driving the flywheel 430 (brushless motor rotor) to rotate.
[0084] In one implementation, it further includes:
[0085] The movement cover 500 is located inside the outer casing 100 and above the bracket 310.
[0086] In this embodiment, the flywheel shaft core 432 is positioned by the upper cover 500 of the mechanism, which facilitates the installation of the flywheel shaft core 432 and guides the reciprocating motion of the bracket 310.
[0087] In one implementation, it further includes:
[0088] Support rod 341 is mounted on large button 340, and the upper cover 500 of the movement has a through hole for support rod 341 to pass through.
[0089] In this embodiment, the support rod 341 ensures that the large button 340 can drive the bracket 310 to move up and down.
[0090] In one implementation,
[0091] Control component 200 includes:
[0092] Control board 210, which is disposed inside housing 100;
[0093] The brushless motor stator winding 250 is disposed inside the housing 100 and is electrically connected to the control board 210.
[0094] The storage battery 220 is disposed inside the housing 100 and is electrically connected to the control board 210.
[0095] The start button 230 is located on the housing 100 and is electrically connected to the control board 210. The start button 230 controls the opening of the flywheel 430 and energizes the stator winding 250 of the brushless motor, driving the flywheel 430 to rotate.
[0096] In one implementation,
[0097] USB interface 240 is located on the outer casing 100.
[0098] In this embodiment, the USB interface 240 outputs 5V DC power, which can be used to charge the mobile phone.

[0100] The lanyard 600 is mounted on the outer casing 100.
[0101] In this embodiment, the lanyard 600 facilitates the carrying of the outer casing 100 and the retrieval of the power generation device.
