All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.

It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one.

The power generation device and the electronic device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1 to 5, an embodiment of the present application discloses a power generation device, which includes a pressing member 100, a screw transmission mechanism, a rotation output member 400, and a power generator 500. The power generation device is a device which applies pressing force to the pressing member 100 by external force such as manual action, and further drives the generator 500 to generate power.

The pressing piece 100 is movably arranged relative to the rotation output part 400, the pressing piece 100 can move linearly under the action of external force pressing, the screw transmission mechanism serves as a transmission mechanism capable of converting linear motion into rotary motion, the linear motion of the pressing piece 100 is converted into rotary motion of the rotation output part 400 through the screw transmission mechanism, and the generator 500 is driven to run to generate electricity.

The screw transmission mechanism comprises a moving rod 200 and a rotating sleeve 300, wherein the rotating sleeve 300 is sleeved on the moving rod 200, one of the rotating sleeve 300 and the moving rod 200 is provided with a guide rail in a spiral shape, the other one of the rotating sleeve 300 and the moving rod 200 is provided with a first bulge, the first bulge extends into the guide rail and can move along the spiral direction of the guide rail, namely, the rotating sleeve 300 is in transmission fit with the moving rod 200 in the spiral direction.

Alternatively, the guide rail may be provided on the inner wall of the rotary sleeve 300 and the first protrusion may be provided on the moving bar 200, or the guide rail may be provided on the moving bar 200 and the first protrusion may be provided on the inner wall of the rotary sleeve 300.

Specifically, the guide rail can be a spiral guide groove, and the first protrusion extends into the guide groove through a notch of the guide groove and can move along the spiral direction of the guide groove; the guide rail also can be spiral helicine guiding hole, and the pore wall of guiding hole is equipped with the opening, and the opening is spiral helicine bar opening, and first arch stretches into in the guiding hole through the opening to can follow the helical direction removal of guiding hole. Of course, the guide rail may be another guide structure, and the rotation sleeve 300 and the moving rod 200 may be in transmission fit in the spiral direction.

If one of the rotary sleeve 300 and the moving rod 200 is fixed, the other can move in a spiral direction with respect to the fixed one; if one of the rotating sleeve 300 and the moving bar 200 is linearly moved in the axial direction, the other can be rotated about the axis, and in short, one of the rotating sleeve 300 and the moving bar 200 can be moved in a spiral direction with respect to the other.

The moving rod 200 is connected to the pressing member 100, and the moving rod 200 is movable along the axis of the moving rod 200 with the pressing member 100 by applying a force to the pressing member 100. Specifically, the movable rod 200 and the pressing member 100 may be fixedly connected by welding, bonding, or the like, or detachably connected by clamping, screwing, or the like, so that the movable rod 200 may move along with the pressing member 100.

Since the movable rod 200 is in limit fit with the pressing member 100 in the axial direction of the movable rod 200, the movable rod 200 and the pressing member 100 do not rotate relatively in the axial direction during pressing. Optionally, under the condition that carriage release lever 200 can dismantle with pressing piece 100 and be connected, can set up square structure at the tip of carriage release lever 200, pressing piece 100 sets up square groove towards the lateral part of carriage release lever 200, and square structure stretches into square inslot, and square structure cooperatees with square groove, so, because square groove is to square structure's limiting displacement, square structure can not rotate relative to square groove, carriage release lever 200 just can't take place relative rotation about the axis relative to pressing piece 100 yet. Of course, in the case where the moving rod 200 is fixedly connected to the pressing member 100, the moving rod 200 is less likely to rotate relative to the pressing member 100, and the moving rod 200 and the pressing member 100 can be also brought into the limit fitting in the axial direction.

Because the rotating sleeve 300 is in transmission fit with the moving rod 200 in the spiral direction, in the process that the moving rod 200 moves along the axis direction, the rotating sleeve 300 rotates around the axis, meanwhile, the rotating sleeve 300 can drive the rotating output part 400 to rotate synchronously, the rotating output part 400 is connected with the generator 500, and under the condition that the rotating output part 400 rotates, the rotating output part 400 drives the generator 500 to operate, and the generator 500 generates electricity.

Specifically, the rotation output part 400 is fixedly connected to the power input shaft of the generator 500, and in an optional scheme, an axis of the power input shaft of the generator 500 is identical to an axis of the moving rod 200, alternatively, the rotation output part 400 and the power input shaft of the generator 500 may be fixedly connected by welding or the like, or other fixed connection manners may be adopted, so that the rotation output part 400 rotates while driving the power input shaft of the generator 500 to rotate synchronously.

According to the arrangement, an external power supply such as a battery or a mobile power supply is not needed, the pressing piece 100 is pressed by an external force, the generator 500 can be operated to generate electricity, the problem that the battery capacity and the mobile power supply capacity of the electronic equipment are limited in the related art is solved, the mobile power supply does not need to be carried, and the carrying inconvenience is avoided.

In an alternative embodiment, the guide rail is a first recess corresponding to the guide groove, the moving rod 200 is provided with a first thread, the rotating sleeve 300 is provided with a second thread, wherein the gap formed between two adjacent circles of the first thread is a first recess, and the second thread is a first protrusion, in this case, the second thread extends into the gap formed between two adjacent circles of the first thread and can move along the gap; or, a gap formed between two adjacent circles of the second threads is a first recess, and the first threads are first protrusions, in this case, the first threads extend into the gap formed between two adjacent circles of the second threads and can move along the gap.

That is, the moving rod 200 and the rotating sleeve 300 are engaged with each other by screw threads, which corresponds to the moving rod 200 having both the first recess and the first protrusion, and the rotating sleeve 300 having both the first protrusion engaged with the first recess of the moving rod 200 and the first recess engaged with the first protrusion of the moving rod 200.

So set up, make carriage release lever 200 and rotating sleeve 300 mutually support through the screw thread, the relative motion between carriage release lever 200 and the rotating sleeve 300 is more steady, improves stability.

In this embodiment, as shown in fig. 3 to 4, in order to ensure that the generator 500 can continuously generate power, when the movable rod 200 is pressed and moved to a certain position, the pressing member 100 and the movable rod 200 need to be returned to the original position in opposite directions, and after the original position is returned, the pressing member 100 can be pressed and moved again, that is, the pressing member 100 reciprocates in the axial direction of the movable rod 200. During the reciprocating movement of the movable rod 200, the rotary sleeve 300 also rotates in the forward or reverse direction about the axis of the movable rod 200 and does not rotate all the way in the same direction. It should be noted that "forward rotation" and "reverse rotation" respectively refer to two opposite directions of rotation of the rotating sleeve 300 about the axis of the moving rod 200.

Alternatively, the rotary sleeve 300 may be fixedly connected to the rotary output member 400, that is, the rotary output member 400 rotates synchronously with the rotary sleeve 300. In this way, the rotation output member 400 rotates forward or backward along with the rotation sleeve 300, and the power input shaft of the generator 500 also rotates forward or backward along with the rotation output member 400, and since the generator 500 generally uses the electromagnetic induction principle, and cuts the magnetic induction lines during the rotation to generate current, the generator 500 can cut the magnetic induction lines to generate current constantly regardless of the forward rotation or the forward rotation, and generate power constantly.

In this embodiment, the pressing member 100 is sleeved on the rotation output part 400, and the pressing member 100 can move along the axis relative to the rotation output part 400, and the rotation output part 400 is in sliding fit with the pressing member 100 in the spiral transmission direction around the axis of the moving rod 200. Specifically, as shown in fig. 1 to 5, the pressing member 100 and the rotation output member 400 are both cylindrical structural members, and the inner wall of the pressing member 100 is engaged with the outer wall of the rotation output member 400, and both of them can slide relatively along the axis of the moving rod 200 and can rotate relatively around the axis of the moving rod 200, so that the relative movement of the rotation output member 400 and the pressing member 100 around the screw transmission direction is realized.

In this arrangement, the pressing tool 100 can be stably moved in the axial direction by the stopper action of the rotation output member 400 due to the fitting relation, and similarly, the rotation output member 400 can be stably rotated about the axis of the movable rod 200 by the stopper action of the pressing tool 100.

As mentioned above, the pressing member 100 reciprocates along the axial direction of the moving rod 200, and when the moving rod 200 is pressed to a certain position, the moving rod 200 is required to return to the original position in the opposite direction, and the return process can also be achieved by a manual action, for example, the pressing member 100 can be clamped by a finger to move the pressing member 100 in the opposite direction to the pressing direction. However, the manual return mode is not as labor-saving as pressing, and the manual switching between pressing and returning is slow, which reduces the power generation efficiency.

In order to solve the above problem, the power generating apparatus further includes an elastic restoring member 700, the elastic restoring member 700 being disposed between the pressing member 100 and the rotation output part 400, the elastic restoring member 700 being capable of driving the pressing member 100 to move in a first direction, which is opposite to a moving direction when the pressing member 100 is pressed, i.e., the above-mentioned restoring direction of the pressing member 100. Specifically, the elastic restoring member 700 may be a spring, which is sleeved on the outer circumference of the rotation output part 400, and one end of the spring abuts against the rotation output part 400 and the other end abuts against the pressing member 100. When the pressing member 100 moves under the pressing action, the spring is elastically deformed and compressed, and the elastic acting force of the spring acting on the pressing member 100 is opposite to the pressing acting force; when the pressing force disappears, the pressing member 100 moves in the opposite direction, i.e., the return direction, under the action of the elastic force, in the process, the spring slowly recovers the elastic deformation, the elastic force is gradually reduced until the elastic force is zero, the pressing member 100 is stationary, and at this time, the pressing member 100 returns to the initial position before being pressed and moved.

So set up, reset piece 700 through elasticity, can make pressing member 100 along the automatic home position that restores of first direction, need not with the help of other external force, convenient and fast improves the generating efficiency.

Specifically, as shown in fig. 1 to 5, the pressing member 100 includes a cylindrical portion 110 and a first limit flange 120, the first limit flange 120 is disposed at a first end portion of the cylindrical portion 110, the first end portion is an end portion of the cylindrical portion 110 adjacent to the generator 500, the first limit flange 120 is located outside the cylindrical portion 110, the rotation output member 400 is disposed inside the cylindrical portion 110, an end portion of the rotation output member 400 adjacent to the generator 500 is also provided with a second limit flange 411, and the second limit flange 411 is disposed opposite to the first limit flange 120 and is sequentially disposed along the axial direction. The first and second position-defining flanges 120 and 411 are sequentially disposed in a moving direction of the pressing member 100 when pressed, and the elastic restoring member 700 is disposed between the first and second position-defining flanges 120 and 411. That is, one end of the spring abuts against the first position-defining flange 120 and the other end of the spring abuts against the second position-defining flange 411.

In this embodiment, the first position-restricting flange 120 and the cylindrical portion 110 may be integrally formed, and the second position-restricting flange 411 and the rotation output member 400 may be integrally formed.

Optionally, the first position-limiting flange 120 is a protruding structure on the outer periphery of the cylindrical portion 110, and the protruding structure may be a plurality of protrusions distributed along the circumferential direction of the cylindrical portion 110, may also be an annular protrusion, and may also be other structures; similarly, the second position-limiting flange 411 is disposed outside the rotation output member 400, and the second position-limiting flange 411 may be a plurality of protrusions distributed along the circumferential direction of the rotation output member 400, or may be an annular protrusion or other structures, and may limit the end of the elastic restoring member 700. In this embodiment, the first position-defining flange 120 and the second position-defining flange 411 are each an annular projection.

With such an arrangement, the elastic resetting piece 700 is located between the first limiting flange 120 and the second limiting flange 411 which are oppositely arranged, so that a regular elastic driving is facilitated, and the driving process of the elastic resetting piece 700 on the pressing piece 100 is more stable.

In other embodiments, the elastic reset element 700 may be replaced by an electromagnetic assembly, the electromagnetic assembly includes two magnets with the same polarity, one of the magnets is disposed on the first position-limiting flange 120, the other magnet is disposed on the second position-limiting flange 411, the two magnets approach each other during the pressing direction of the pressing element 100, the opposing force gradually increases, and when the pressing action is eliminated, the opposing force between the two magnets drives the pressing element 100 to move in the opposite direction. Alternatively, both magnets may be ring-shaped.

Specifically, the rotation output component 400 is a cylindrical structure, the rotation output component 400 includes a cylinder portion 410 and a sealing cover 420, an inner cavity is an inner space of the cylinder portion 410, the rotation sleeve 300 extends into the inner cavity through a port of the cylinder portion 410, the rotation sleeve 300 can be fixedly connected with an inner wall of the cylinder portion 410, the rotation sleeve 300 can also be in transmission connection with the inner wall of the cylinder portion 410, and the rotation sleeve 300 can drive the cylinder portion 410 to rotate.

The sealing cover 420 is inserted into the port of the barrel 410 and blocks the port, the avoiding hole 421 is arranged on the sealing cover 420, and the sealing cover 420 blocks the rotating sleeve 300 from leaving the inner cavity.

So set up, rotate output part 400 and surround and rotate cover 300, rotate cover 300 and the inner chamber of rotating output part 400 and be connected, rotate cover 300 and rotate the contact surface between the output part 400 and can be bigger, rotate the rotation moment of torsion of cover 300 and change and transmit for rotating output part 400, guarantee to rotate output part 400 and rotate smoothly.

Of course, in other embodiments, the outer surface of the rotating sleeve 300 may be directly connected to the surface of the rotation output member 400, so that the rotating sleeve 300 can drive the rotation output member 400 to rotate.

In this embodiment, as shown in fig. 1, the rotation output member 400 further includes an axial extension 440, an axis of the axial extension 440 is coincident with an axis of the moving rod 200, and the axial extension 440 is connected to a power input end of the generator 500. In this way, the rotating sleeve 300 drives the cylinder portion 410 to rotate, and the axial extension portion 440 rotates synchronously with the cylinder portion 410, thereby driving the power input end of the generator 500 to rotate.

In an alternative embodiment, the axial extension 440 and the barrel 410 are an integrally formed structure. Therefore, the transmission between the axial extension part 440 and the cylinder part 410 is more accurate, the axial extension part 440 and the cylinder part 410 stably and synchronously rotate, the axial extension part 440 is prevented from being broken due to untimely torque transmission, and the reliability and the safety are improved.

Alternatively, the rotating sleeve 300 and the rotating output member 400 are connected in a transmission connection manner, in this embodiment, as shown in fig. 1, the inner wall of the rotating output member 400 is provided with a first engaging tooth 431, the rotating sleeve 300 is provided with a second engaging tooth 310, the second engaging tooth 310 can be provided on the outer circumferential surface of the rotating sleeve 300, and the first engaging tooth 431 is engaged with the second engaging tooth 310. Specifically, the rotary sleeve 300 may be fixed in position relative to the rotary output member 400, such that the first engagement teeth 431 and the second engagement teeth 310 are continuously engaged, and thus, whether the rotary sleeve 300 rotates forward or backward around the axis of the moving rod 200, the rotary sleeve 300 always drives the rotary output member 400 to rotate, and the generator 500 continuously operates to generate electricity, and continuously generates current.

In other embodiments, the rotating sleeve 300 and the rotating output component 400 may be fixedly connected by welding, bonding, or the like, or detachably connected, so that the rotating sleeve 300 can drive the rotating output component 400 to rotate.

So set up, can not only through the cooperation of first meshing tooth 431 and second meshing tooth 310, realize rotating sleeve 300 and be connected with the transmission that rotates output unit 400, make and rotate sleeve 300 and drive rotation output unit 400 and rotate, and then drive generator 500 operation electricity generation, can also be through the separation of first meshing tooth 431 and second meshing tooth 310, realize rotating output unit 400 and the separation and the dismantlement of rotating sleeve 300, the power generation facility's of being convenient for installation and dismantlement.

As mentioned above, during the reciprocating movement of the pressing member 100, the rotation output part 400 rotates forward and backward along with the rotating sleeve 300, so that the generator 500 continuously generates electricity. In the process that the pressing member 100 is restored and displaced along the driving direction of the elastic restoring member 700, the pressing member 100 and the moving rod 200 need to drive the rotation output member 400 to rotate reversely through the rotating sleeve 300, since the rotating sleeve 300 drives the rotation output member 400 to rotate, the resistance of the rotation output member 400 to hinder the rotation is borne, the rotation of the rotating sleeve 300 is not smooth enough, the restoring and displacement processes of the moving rod 200 and the pressing member 100 are also resisted, and the pressing member 100 is difficult to restore to the initial position before being pressed.

In order to solve the above problem, as shown in fig. 2 to 4, the inner wall of the rotation output member 400 is provided with an annular protrusion 430, the rotating sleeve 300 is in limit contact with the annular protrusion 430 in the pressing direction of the pressing member 100, and the rotating sleeve 300 is in limit contact with the cap 420 of the rotation output member 400 in a first direction opposite to the pressing direction of the pressing member 100, and the distance between the annular protrusion 430 and the cap 420 is greater than the size of the rotating sleeve 300 along the axial direction of the moving rod 200, so that the rotating sleeve 300 has a certain moving range between the annular protrusion 430 and the cap 420. The first engagement teeth 431 are provided at the side of the annular protrusion 430, and the second engagement teeth 310 are also provided at the side of the rotating sleeve 300, with the first engagement teeth 431 facing the rotating sleeve 300, and the second engagement teeth 310 facing the annular protrusion 430. The plane of the first engaging tooth 431 and the plane of the second engaging tooth 310 are both perpendicular to the axial direction of the moving rod 200.

Specifically, when the pressing member 100 moves under the pressing action, the moving rod 200 and the rotating sleeve 300 move in the same direction along with the pressing member 100 until the rotating sleeve 300 is in contact fit with the annular protrusion 430, and under the condition that the annular protrusion 430 is in contact with the rotating sleeve 300, the first meshing tooth 431 and the second meshing tooth 310 are meshed, which indicates that the rotating sleeve 300 is in transmission connection with the rotation output part 400, and at this time, the rotating sleeve 300 can drive the rotation output part 400 to rotate, and the generator 500 generates electricity; when the pressing member 100 moves back along the driving direction of the elastic restoring member 700, the rotating sleeve 300 is disengaged from the annular protrusion 430 and is in limited contact with the sealing cover 420, at this time, the first engaging teeth 431 and the second engaging teeth 310 are disengaged from each other, the rotating sleeve 300 and the rotating output member 400 are in a transmission disengaged state, the rotating sleeve 300 cannot drive the rotating output member 400 to rotate, and the generator 500 does not generate electricity.

With such an arrangement, when the pressing member 100 moves under the pressing action, the rotation output part 400 rotates, the generator 500 runs to generate electricity, when the pressing member 100 returns to the displacement, the rotation output part 400 stands still, the generator 500 does not generate electricity, so that the pressing member 100 cannot bear the resistance torque transmitted by the rotation output part 400 in the returning process, and the returning process is smoother.

In the present embodiment, as shown in fig. 1 to 2, the first meshing teeth 431 and the second meshing teeth 310 are each at least two sets and correspond to each other one by one in the axial direction of the axis.

So set up, the transmission between rotating sleeve 300 and rotating output part 400 is more accurate, and the increase moment of torsion avoids rotating sleeve 300 and takes place the section, and reliability and security improve.

Optionally, the first and second engagement teeth 431, 310 are both ratchet teeth. Specifically, in the case where the rotary sleeve 300 is in contact with the annular protrusion 430, only when the rotary sleeve 300 rotates in a specific direction, the two ratchet teeth are engaged, so that the transmission connection between the rotary sleeve 300 and the rotation output part 400 is realized; if the rotary sleeve 300 is rotated in the opposite direction of the specific direction, even if the rotary sleeve 300 is brought into contact with the annular protrusion 430, the two ratchet teeth are actively separated, and the rotary sleeve 300 and the rotation output member 400 are disengaged from the transmission.

So set up, avoid the pressing part 100 to reply the removal, and under the condition that first meshing tooth 431 and second meshing tooth 310 do not break away from completely, first meshing tooth 431 and second meshing tooth 310 mesh mutually, and then avoid replying the displacement in-process and rotate cover 300 and produce the resistance, guarantee to rotate cover 300 and rotate the one-way transmission between the output unit 400, and then guarantee going on smoothly of pressing part 100 reset process.

In a further technical solution, as shown in fig. 2-4, the moving rod 200 is provided with a limiting structure 210, and the limiting structure 210 and the rotating sleeve 300 can be in limiting contact in the moving direction of the pressing member 100. In this embodiment, the limiting structure 210 may be a limiting block, or may be another structure, and the position of the rotating sleeve relative to the moving rod may be limited.

Alternatively, the moving direction of the pressing member 100 may be the moving direction during the elastic resetting of the pressing member 100, in which case, the limiting structure 210 is disposed at one end of the moving rod 200 away from the end cap assembly, and the limiting structure 210 is located in the inner cavity of the rotation output part 400. Thus, by the limiting structure 210, the pressing piece 100 is prevented from driving the moving rod 200 to enable the rotating sleeve 300 to be separated from the moving rod 200 in the resetting process, and smooth proceeding of subsequent spiral transmission is guaranteed.

Of course, the moving direction of the pressing member 100 may refer to the moving direction when the pressing member 100 is pressed, in this case, the limiting structure 210 is disposed on the moving rod 200 and is located at a side of the rotating sleeve 300 close to the end cap assembly, that is, the limiting structure 210 is located inside the pressing member 100. In this way, the stopper structure 210 can limit the stroke distance of the pusher 100 during the pushing movement, thereby preventing an excessive movement distance.

Here, "number of revolutions" means number of revolutions, and the angular velocity increases as the number of revolutions increases.

Under the condition that the transmission set is one, the rotation input end is arranged on the driving gear, and the rotation output end is arranged on the driven gear. Therefore, the driving gear is meshed with the transmission gear, the linear speeds of the driving gear and the transmission gear are the same, and the diameter of the driven gear is smaller than that of the driving gear, so that the angular speed of the driven gear is larger than that of the driving gear, the rotating speed of the driven gear is also larger than that of the driving gear, the rotating speed of the rotating output end is larger than that of the rotating input end, and finally the rotating speed is increased.

Further, under the condition that the number of the transmission sets is two or more, in two adjacent transmission sets, along the power transmission direction, the driven gear of the first transmission set is coaxially connected with the driving gear of the second transmission set, the angular speed and the rotating speed of the driven gear of the first transmission set are the same, the diameter of the driven gear of the first transmission set is smaller than that of the driving gear of the second transmission set, and the rotating speed of the second transmission set is further increased on the basis of increasing the rotating speed of the first transmission set. In this way, the rotational speed is increased in multiple stages by two or more transmission sets, and the rotational speed is further increased.

Of course, in other embodiments, the transmission set may include a synchronous pulley and a synchronous belt, and may also include a sprocket and a chain, or other transmission forms, and it is sufficient that the transmission connection between the two transmission wheels can be realized.

In this way, the speed increasing mechanism 600 can increase the rotation speed of the power input shaft of the generator 500, thereby further improving the power generation efficiency.
