DETAILED DESCRIPTION

[0042] The application will be further described in detail below with reference to the accompanying drawings, which are explanatory rather than limiting of the application:

[0046] As Figure 5 In a preferred embodiment of the present application, the spatial crank slider mechanism comprises a rotating compass 2, a rotating transmission shaft 3 and a plurality of fixed shafts 20-1, one end of the plurality of fixed shafts 20-1 is connected with the shell 19, the other end is connected with a support plate, the rotating compass 2 is rotatably connected with the support plate; the rotating arm 1 is connected with the rotating compass 2, the rotating compass 2 is connected with the rotating transmission shaft 3, and the rotating transmission shaft 3 is connected with one end of the main shaft guide rail 4. Preferably, the fixed shaft 20-1 is sleeved with a shaft sleeve 20-3, the main shaft guide rail 4 is sleeved with a fixed sleeve cap 20-2, and the shaft sleeve 20-3 and the fixed sleeve cap 20-2 are connected through an extensible connecting rod 20-4; the two ends of the rotating transmission shaft 3 are connected with the rotating compass 2 and the fixed sleeve cap 20-2 through rolling bearings respectively. When hand cranking, the fixed sleeve cap 20-2 is sleeved on the main shaft guide rail 4 and fixed, and after hand cranking is completed, the fixed sleeve cap 20-2 is removed, and the extensible connecting rod 20-4 is correspondingly extended and retracted, so that it is fixed on the sleeve cap fixing rod beside it.

The rotating arm 1 is fixedly connected with the top compass of the rotating compass 2, thereby driving the connected shaft and the bottom compass of the rotating compass 2 to rotate synchronously, and the rotating movement of the bottom compass drives the rotating transmission shaft 3 to move, thereby changing the movement direction and making the main shaft guide rail 4 move up and down. In order to realize Figure 5 The fixed shaft 20-1 in the Figure 5 The fixed shaft 20-1 in the

[0047] As Figure 11In order to fix the structure of the sleeve cap 20-2, the use and end of the rotating power generation mode are realized by the structure of the sleeve cap 20-2, the hexagonal screw is screwed into the sleeve cap hole and is tightly fixed, the sleeve cap hole includes a threaded part and a non-threaded part.

When the rotating power generation exits the use, the screw is screwed into the non-threaded space, so that the screw is immediately withdrawn from the main shaft hole fixedly connected with the main shaft under the action of the spring, and the screw is still fixed in the sleeve cap 20-2 and is not lost due to the limiting action of the hexagonal nut and the baffle, and the risk of screw loss is greatly reduced.

[0048] In a preferred embodiment of the present application, the number of the vibration spring shafts 7 is 2, and the two vibration spring shafts 7 are symmetrically arranged along the axis of the main shaft guide rail 4, and the spring coefficients of the vibration springs 8 on the two vibration spring shafts 7 are equal.

[0049] In a preferred embodiment of the present application, the vibration spring shaft 7 is provided with the spring limiting column 6.

[0050] As Figure 4 In a preferred embodiment of the present application, the pressing transmission mechanism 10 includes the telescopic spring 10-1, the roller 10-2, the fixed track 10-3 and the pressing connecting rod 10-4; the pressing switch 9 is connected with the telescopic spring 10-1 through the pressing connecting rod 10-4, the telescopic spring 10-1 is connected with the scissors type pressing mechanism 12, the fixed track 10-3 is arranged on the upper and lower sides of the scissors type pressing mechanism 12, and the scissors type pressing mechanism 12 is connected with the fixed track 10-3 through the roller 10-2.

[0051] In a preferred embodiment of the present application, the T-shaped sliding sleeve 21 and the vibration spring shaft 7 are connected through a bearing, the shaft center is a stainless steel cylinder, and the bearing of the moving part can be a linear bearing or an oil-free bushing.

[0052] In a preferred embodiment of the present application, the linear bearings 14 are arranged at the two ends of the main shaft guide rail 4, the inner diameter of the linear bearing 14 at the upper end is smaller than that of the linear bearing 14 at the lower end.

[0053] The theoretical basis of the present application is as follows:

[0054] The present application internally adopts a spring amplitude amplification structure with two cylindrical springs matched, and the principle diagram is as follows: Figure 6As shown, from E = BLV and V∝Z, where B is the magnetic field strength, L is the coil length, V is the relative velocity between the coil and the magnet, and Z is the relative displacement between the coil and the magnet, it is easy to see that increasing the vibration amplitude output response can improve the collection of vibration energy. The power generation method adopts moving coil power generation (the mass of the moving part is m), that is, the magnet is stationary relative to the entire device, while the coil undergoes relative displacement due to inertia. In the figure, x is the displacement of the device, y is the displacement response of the coil, and the relative displacement between the coil and the magnet is z, which satisfies z = yx. K is the spring constant, and c is the damping.

[0055] The differential equations of motion can be obtained from the dynamic model:

[0056]

[0057] Its steady-state solution is:

[0058]

[0059] The natural frequency of the spring amplitude amplification mechanism is:

[0060]

[0061] From critical damping c c =2mw n Damping coefficient have to:

[0062] c=2mξw n (4)

[0063] Substituting formulas (2) and (3) into (4) yields:

[0064]

[0065] make have to:

[0066]

[0067] From (6), we can see that when This can achieve amplitude amplification. For example... Figure 7 When the damping is constant, when The vibration energy harvesting effect is best when the amplitude is at its maximum.

[0068] To enable the motor to collect more vibration energy, the spring constant of the vibration spring 8 should satisfy:

[0069]

[0070] The bottom of the power generation device uses a scissor-type pressing mechanism 12, the structure of which is as follows: Figure 8 As shown:

[0071] Let the arm length be L, the angle between the two arms be a, the horizontal distance between the two arms be x, the height between the two arms be h, and the total height of the structure be H, then:

[0072]

[0073]

[0074]

[0075] The structure design can effectively introduce the pressing displacement, thereby reducing the pressing amplitude variation, and further improving the pressing frequency.

[0076] The power generation process is labor-saving, and the space slider crank structure is used at the top of the power generation device, and the principle is as shown in Figure 9 .

[0077] Suppose that the end point A of the crank is located on the horizontal line segment OB at the initial moment, and the crank rotates an angle of θ from the initial position, and the acute angle between the connecting rod AB and OB is α (referred to as the swing angle).

[0078] Taking point O as the coordinate origin and the direction of OB as the coordinate axis on the x-axis, the displacement of the slider is represented by x, that is, the length of the side OB. It is obtained that:

[0079]

[0080]

[0081] Approximation of the model: because (1+ε) α =1+αε+..., ε<1. Generally, r 2 / l 2 is much smaller than 1, so the approximate model of the slider displacement is:

[0082]

[0083] Let the angular velocity be ω, and the linear velocity of the rotating compass be V1, then:

[0084]

[0085] The velocity V2 of the slider is equal to V1. The design of the structure not only can perform rotating hand-cranking power generation, but also effectively solves the single power generation mode compared with the traditional power generation mode, and the rotating hand-cranking power generation can save labor, and effectively solves the problem of human body fatigue.

[0086] The novel emergency backup multi-mode power generation device disclosed by the application is based on a cylindrical linear generator, as shown in Figure 10 .

[0087] The magnets on the motor's mover spindle are displaced relative to the stator under the action of a spring, and the windings in the slots cut the magnetic lines of force to generate voltage. The motor stator consists of two flanged linear bearings of different diameters, coils, a back iron, and slots. The larger diameter linear bearing, located near the spring, has a larger inner diameter to meet the load requirements as it bears the main load. A larger inner diameter results in greater radial runout. To limit the radial runout of the mover spindle bearing and reduce the air gap length, a smaller diameter linear bearing above the motor limits the movement of the guide rail spindle. The two linear bearings and the mover spindle use a clearance fit, ensuring coaxiality between the mover and stator while minimizing friction through rolling friction. The coils are wound clockwise and counterclockwise in the slots. In the mover section, annular magnets are alternately placed on the linear bearings according to their magnetization method. The permanent magnet uses a radially magnetized cylindrical permanent magnet, which has a simple winding structure, facilitates magnetization, has high manufacturing efficiency, and results in minimal magnetic leakage. The cylindrical spring causes the motor's rotor to move asynchronously, and with proper spring design, it can amplify the amplitude. An anti-loosening nut is installed on the upper part of the magnet to make the generator more secure. The coil frame 15 is made of composite resin material; while ensuring sufficient mechanical strength, it should be as thin as possible to save costs.

[0088] The basic principles of power generation vary depending on the power generation method used in operation: when using rotary hand-crank or push-button power generation, the power generation principle is moving magnet type, that is, the main shaft guide rail 4 and the magnets distributed around it move back and forth in the vertical direction, while the central straight cylinder composed of linear bearing 14, coil frame 15 and back iron 16 remains stationary; when using vibration power generation, the power generation principle is moving coil type, that is, the central straight cylinder composed of linear bearing 14, coil frame 15 and back iron 16 moves up and down, thereby moving the coil on the coil frame 15 up and down, while the main shaft guide rail 4 and the magnets around it remain stationary.

[0089] The working principle and method of the present invention will be further explained below with reference to a specific embodiment:

[0090] Rotary arm 1 is located at the top of the entire power generation device, connected with rotary transmission shaft 3, constituting a spatial crank slider mechanism, through rotating rotary arm 1 to drive compass 2 to rotate, can make rotary transmission shaft 3 drive main shaft guide rail 4 to do vibration movement along the up and down direction, the outside of main shaft guide rail 4 is wrapped by the center straight cylinder composed of linear bearing 14, coil skeleton 15 and back iron 16, the upper and lower ends of the center straight cylinder are fixed by limiting ring 13, two vibration spring shafts 7 are distributed on the two sides of the center straight cylinder, vibration spring 8 is arranged on each vibration spring shaft 7, spring limiting column 6 is arranged on the upper part of spring vibration shaft 7, scissor type pressing mechanism 12 is connected at the bottom of main shaft guide rail 4, base 11 is connected at the bottom of scissor type pressing mechanism 12, shell 19 tightly wraps the parts, pressing switch 9 is connected with scissor type pressing mechanism 12 through pressing transmission mechanism 10, which is located at the bottom of shell 19 on one side.

[0091] The above device has the following three working modes when working:

[0092] Vibration power generation: the basic principle of this power generation mode is moving coil type, first open limiting ring 13, so that the center straight cylinder composed of linear bearing 14, wire slot 15 and back iron 16 can move up and down, and the main shaft guide rail 4 and the magnets distributed around it remain static, then open the locking handle 17 and the locking link 18, when the power generation device extracts vibration energy, the vibration spring 8 will vibrate, the center straight cylinder will vibrate up and down through the T-shaped sliding sleeve 21, so that the coil on the coil skeleton 15 generates relative displacement with the magnets around the main shaft guide rail 4, cuts the magnetic induction line and completes power generation.

[0093] Pressing power generation: first apply force to pressing switch 9, drive pressing transmission mechanism 10 to move, so that scissor type pressing mechanism 12 extends and retracts, thereby driving the top main shaft guide rail 4 to move up and down, the magnets distributed around the main shaft guide rail 4 also move up and down, the center straight cylinder composed of linear bearing 14, coil skeleton 15 and back iron 16 outside the main shaft guide rail 4 remains static, the coil on the coil skeleton 15 generates relative displacement with the magnets around the main shaft guide rail 4, cuts the magnetic induction line, thereby completing power generation.

[0094] Rotary hand generator: by shaking the rotating arm 1, the rotating compass 2 is moved, and the rotating transmission shaft 3 is moved, and the rotating transmission shaft 3 is connected with the main shaft guide rail 4. When the rotating arm 1 rotates clockwise, the rotating shaft 3 is driven to rotate clockwise by the rotating compass 2, and the main shaft guide rail 4 is driven to move upward, and the outer part of the main shaft guide rail 4 is wrapped by the center straight cylinder composed of linear bearing 14, coil former 15 and back iron 16, which remains stationary, the coil on the coil former 15 generates relative displacement with the magnet around the main shaft guide rail 4, cuts the magnetic induction line and generates voltage; when the rotating arm 1 rotates counterclockwise, the rotating transmission shaft 3 is driven to rotate counterclockwise by the rotating compass 2, and the main shaft guide rail 4 is driven to move downward, and the outer part of the main shaft guide rail 4 is wrapped by the center straight cylinder composed of linear bearing 14, coil former 15 and back iron 16, which remains stationary, the coil on the coil former 15 generates relative displacement with the magnet around the main shaft guide rail 4, cuts the magnetic induction line and generates voltage to complete power generation.

[0095] The power generation device adopts a plurality of different limit switches, which are reasonably designed and can fix the internal power generation structure firmly to prevent shaking and displacement during power generation.
