Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As used herein, "electronic device" means a device capable of receiving and/or transmitting communication signals including, but not limited to, a device connected via any one or more of the following connections:

(1) via wireline connections, such as via Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital cable, direct cable connections;

(2) via a Wireless interface means such as a cellular Network, a Wireless Local Area Network (WLAN), a digital television Network such as a DVB-H Network, a satellite Network, an AM-FM broadcast transmitter.

Electronic devices arranged to communicate over a wireless interface may be referred to as "mobile terminals". Examples of mobile terminals include, but are not limited to, the following electronic devices:

(1) satellite or cellular telephones;

(2) personal Communications Systems (PCS) terminals that may combine cellular radiotelephones with data processing, facsimile, and data Communications capabilities;

(4) conventional laptop and/or palmtop receivers;

(5) conventional laptop and/or palmtop radiotelephone transceivers, and the like.

Referring to fig. 1 and fig. 2, in an electronic device 100 provided in an embodiment of the present application, the electronic device 100 may be a mobile phone or a tablet computer, which is not limited herein.

As shown in fig. 3, the electronic device 100 includes a display screen 10, a housing 20, and a power supply device 30.

The display screen 10 is connected to the housing 20 to form an accommodating space, and components such as the power supply device 30 and the main board of the electronic device 100 are disposed in the accommodating space.

The housing 20 may be an integral structure or may be formed by connecting a plurality of separate structures. For example, in some embodiments, the housing 20 includes a rear cover 22 and a middle frame 21, and the rear cover 22 and the display screen 10 are respectively attached to both sides of the middle frame 21. The middle frame 21 may be made of metal or plastic, or may be made of glass, and the material of the rear cover 22 may be the same as or different from that of the middle frame 21, and the material of each part structure of the housing 20 is not limited herein.

As shown in fig. 3 to 8, the power supply device 30 includes a transmission shaft 31, a rudder 32, a first transmission wheel 33, a second transmission wheel 34, a turning wheel 35, and a power generation module 36.

The swing rudder 32 is connected with the transmission shaft 31, and the center of gravity of the swing rudder 32 deviates from the axis of the transmission shaft 31, so that the swing rudder 32 can swing inertially around the axis of the transmission shaft 31 when a user moves with the electronic device 100, and then the swing rudder 32 is used for driving the transmission shaft 31 to rotate. The shape of the rudder 32 may be a fan shape, or a rod shape or a block shape, as long as the center of gravity of the rudder 32 is offset from the axis of the transmission shaft 31, so that the rudder 32 can inertially swing around the axis of the transmission shaft 31 when the power supply device 30 moves.

When the swinging rudder 32 is in a fan shape, the central angle of the fan surface can be 60-120 degrees, so that the inertial motion effect of the swinging rudder 32 around the transmission shaft 31 is good.

The first transmission wheel 33 and the second transmission wheel 34 are both connected with the transmission shaft 31. Referring to fig. 5 and 6, when the pivot rudder 32 drives the transmission shaft 31 to rotate in a first direction, the transmission shaft 31 can only drive the first transmission wheel 33 to rotate, and when the pivot rudder 32 drives the transmission shaft 31 to rotate in a second direction, the transmission shaft 31 can only drive the second transmission wheel 34 to rotate in a second direction, the first direction is opposite to the second direction, for example, taking a state that the power supply device 30 is mounted on the electronic device 100 as an example, when the display screen 10 swings from a side, the first direction is clockwise, and the second direction is counterclockwise. Conversely, the first direction is counterclockwise, and the second direction is clockwise.

Because the swinging rudder 32 drives the transmission shaft 31 to rotate in the first direction or the second direction, the transmission shaft 31 can only drive one of the first transmission wheel 33 and the second transmission wheel 34 to rotate all the time, and the first transmission wheel 33 and the second transmission wheel 34 are driven by the transmission shaft 31 to rotate in the opposite direction, therefore, no matter the swinging rudder 32 rotates in the first direction or the second direction around the axis of the transmission shaft 31, one of the first transmission wheel 33 and the second transmission wheel 34 is driven by the transmission shaft 31, so as to fully utilize the inertia force of the swinging rudder 32 around the axis of the transmission shaft 31.

As shown in fig. 7 and 8 in conjunction, the rotary wheel 35 includes a first transmission portion 351 and a second transmission portion 352. The first transmission portion 351 is coupled to the first transmission wheel 33, and the second transmission portion 352 is coupled to the second transmission wheel 34. The rotation direction of the rotating wheel 35 driven by the first driving wheel 33 is the same as the rotation direction of the rotating wheel 35 driven by the second driving wheel 34, that is, no matter the first driving wheel 33 or the second driving wheel 34 drives the rotating wheel 35, the rotation direction of the rotating wheel 35 is uniform, so that on the basis, the power generated by the rotating wheel 35 rotating towards the same direction can be utilized to generate electricity.

As shown in fig. 6 and 9, the power generation module 36 includes a magnet 361 and a coil 362, one of the coil 362 and the magnet 361 is connected to the rotating wheel 35, and when the rotating wheel 35 rotates, the coil 362 makes a magnetic induction line cutting motion in the magnetic field of the magnet 361 to generate a current. Because the rotating wheel 35 always moves towards one direction in the swinging process of the swinging rudder 32, the direction of the current generated by the movement of cutting the magnetic induction line by the coil 362 is unchanged, namely, the power generation efficiency of the power generation module 36 is improved, and meanwhile, under the arrangement of the structure, the coil 362 can generate direct current, so that the power supply circuit structure of the electronic device 100 can be simplified. In this embodiment, the power supply device 30 can automatically generate power with the movement of the electronic device 100 to effectively extend the cruising performance of the electronic device 100 without configuring a battery with a large capacity to maintain the compact design of the electronic device 100.

It should be noted that in some embodiments, the electric energy generated by the coil 362 may be directly used to power a structure of the electronic device 100, such as the display screen 10, or an energy storage element may be provided to store the electricity of the coil 362. For example, the power supply device 30 includes a battery 30a (see fig. 3), and the battery 30a and the coil 362 form a closed circuit, so that the electric energy generated by the coil 362 can be transmitted to and stored in the battery 30 a.

In some embodiments, the power supply device 30 includes a mounting seat (not shown), and the transmission shaft 31 and the rotating wheel 35 are rotatably connected to the mounting seat, so that the structures in the power supply device 30 can be integrated together, and modularization is achieved, thereby facilitating mass production and improving assembly efficiency.

The connection of the first 33 and second 34 transmission wheels to the transmission shaft 31 may be a rotary connection. For example, as shown in fig. 10, the second transmission wheel 34 is provided with a shaft hole 342, and the transmission shaft 31 is rotatably engaged with the shaft hole 342, so that the driving wheel 34 can rotate around the transmission shaft 31.

It should be noted that, in some embodiments, the transmission shaft 31 and the rotating wheel 35 of the power supply device 30 may be disposed on the housing 20. Alternatively, the mounting base is integrally formed with the housing 20.

In some embodiments, the coil 362 may be wound around a rotating shaft 35a connected to the rotating wheel 35, so that when the rotating wheel 35 rotates, the rotating shaft 35a drives the coil 362 to perform a magnetic induction line cutting motion in a magnetic field to generate electricity. It should be noted that, in some embodiments, the coil 362 is configured to be capable of matching with a wireless charging device to adapt to the wireless charging requirement, so that the electronic device 100 can not only automatically generate power by using the power supply device 30, but also conveniently match with an external wireless charging device to meet the multi-scenario use requirement of the electronic device 100.

The first transmission wheel 33 and the rotating wheel 35 can be matched together in a tooth meshing transmission mode, and correspondingly, the second transmission wheel 34 and the rotating wheel 35 can also be matched together in a tooth meshing transmission mode.

For example, as shown in fig. 9, the first transmission wheel 33 and the second transmission wheel 34 are both gears, and the rotating wheel 35 is a duplicate gear. The first transmission wheel 33 is engaged with the first transmission part 351, and the second transmission wheel 34 is engaged with the second transmission part 352 through the intermediate gear 34a, so that the rotating wheel 35 driven by the second transmission wheel 34 can keep consistent with the rotating direction of the rotating wheel 35 driven by the first transmission wheel 33 through the intermediate gear 34a, so that the direction of the coil 362 cutting the magnetic induction lines in the magnetic field of the magnet 361 along with the rotating wheel 35 is kept unchanged, and direct current is output.

The number of the intermediate gears 34a is not limited, and may be 1, 2 or more than 2, as long as the rotating wheels 35 are driven by the first driving wheel 33 and the second driving wheel 34 to have the same rotating direction.

The transmission ratio between the first transmission wheel 33 and the first transmission part 351 is equal to the transmission ratio between the second transmission wheel 34 and the second transmission part 352, so that the rotation speed of the first transmission wheel 33 driving the rotating wheel 35 is equal to the rotation speed of the second transmission wheel 34 driving the rotating wheel 35, and the rotation stability of the rotating wheel 35 is maintained.

In some embodiments, the structure of the first transmission wheel 33 is the same as that of the second transmission wheel 34, so as to reduce the variety of parts.

The structure of the first transmission wheel 33 is equal to the number of teeth and the gear radius of the second transmission wheel 34, and then the initial rotation torque generated by the first transmission wheel 33 when the transmission shaft 31 drives the first transmission wheel 33 is equal to the initial rotation torque generated by the second transmission wheel 34 when the transmission shaft 31 drives the second transmission wheel 34, so that when the pendulum rudder 32 swings inertially around the axis of the transmission shaft 31, the energy loss acting on the first transmission wheel 33 and the second transmission wheel 34 is equal, and the swing amplitude of the pendulum rudder 32 in two opposite directions is equal and gradually attenuated.

As shown in fig. 10 and 11 in conjunction, the power supply device 30 includes a rotating disk 37, and the rotating disk 37 is fixed to the transmission shaft 31 so that the rotating disk 37 rotates together when the transmission shaft 31 rotates. The rotating disk 37 is rotatably provided with a first swing arm 371 and a second swing arm 372. As shown in fig. 9, the first transmission wheel 33 has a plurality of first stopper portions 331 arranged at equal intervals in the axial direction thereof, and the second transmission wheel 34 has a plurality of second stopper portions 341 arranged at equal intervals in the axial direction thereof.

The first swing arm 371 can only unidirectionally drive the first transmission wheel 33 to rotate in the first direction through the first position-limiting portion 331 with the rotating disc 37, and the second swing arm 372 can only unidirectionally drive the second transmission wheel 34 to rotate in the second direction through the second position-limiting portion 341 with the rotating disc 37.

In this embodiment, the first swing arm 371 and the second swing arm 372 on the rotating disc 37 respectively drive the corresponding first driving wheel 33 and second driving wheel 34 to rotate unidirectionally in different directions, so that when the swing rudder 32 swings, only one of the first driving wheel 33 and second driving wheel 34 always rotates, and then the inertia force of the swing rudder 32 is fully utilized as a power source to drive the rotating wheel 35, thereby improving the power generation efficiency.

When the transmission shaft 31 rotates in the first direction, the first driving wheel 33 can rotate along with the rotating disk 37 by the abutting between the first swing arm 371 and the first limiting portion 331, the second swing arm 372 rotates relative to the rotating disk 37 under the abutting between the second limiting portion 341 until the second swing arm 372 passes over the second limiting portion 341, when the transmission shaft 31 rotates in the second direction, the second driving wheel 34 can rotate along with the rotating disk 37 by the abutting between the second swing arm 372 and the second limiting portion 341, and the first swing arm 371 rotates relative to the rotating disk 37 under the abutting between the first limiting portion 331 until the first swing arm 371 passes over the first limiting portion 331.

For the sake of understanding, the operation of the power supply device 30 will be further described below by taking only the example that the rotating disc 37 rotates the second transmission wheel 34.

With reference to fig. 12 to 13, taking the direction of the arrow W1 shown in fig. 12 as the first direction and the direction of the arrow W2 as the second direction as an example, when the transmission shaft 31 is driven by the swing rudder 32 to rotate in the second direction, the second swing arm 372 abuts against the second stopper portion 341 and is limited to the rotating disc 37 in the first direction, that is, the second swing arm 372 cannot move in the first direction relative to the rotating disc 37, so that the rotating disc 37 drives the second swing arm 372 to move in the second direction. As shown in fig. 13, the second swing arm 372 drives the second position-limiting portion 341 to move in the second direction, so that the second transmission wheel 34 rotates in the second direction integrally with the rotating disc 37, and the inertial swing force of the swing rudder 32 is converted into the rotational force of the second transmission wheel 34 in the second direction.

Referring to fig. 14, when the rudder 32 swings back in the first direction, the first driving wheel 33 rotates with the rotating disc 37 in the first direction, and the principle that the second driving wheel 34 rotates with the rotating disc 37 can be referred to. Meanwhile, the second swing arm 372 moves towards the first direction along with the rotating disk 37 and abuts against the next second limiting portion 341, so that the second swing arm 341 rotates relative to the rotating disk 37 under the abutting action, and finally the second swing arm 372 moves over the second limiting portion 341 and returns to the abutting state (shown in fig. 12) of the second swing arm 372 relative to the second limiting portion 341 in the second direction, so that similarly, the second swing arm 372 can be used for being matched with the second limiting portion 341 one by one to drive the second transmission wheel 34, correspondingly, the first swing arm can be used for being matched with the first limiting portion 371 one by one to drive the first transmission wheel 33, and the first swing arm 371 and the second swing arm 372 are alternatively matched with the corresponding first limiting portion 331 and the second limiting portion 341, so that when the rotating disk 37 reciprocates along with the rudder 32, the rotating disk 37 realizes the first transmission wheel 33 and the second transmission wheel 33 through the corresponding first swing arm 371 and second swing arm 372 The wheels 34 are driven alternately, so that the energy conversion of the inertia force of the rudder 32 is improved, the first driving wheel 33 and the second driving wheel 34 which are operated alternately are used for driving the rotating wheel 35 to rotate continuously, higher energy conversion efficiency is obtained, and the cruising performance of the electronic equipment 100 provided with the cover power supply device 30 is improved.

The first swing arm 371 and the second swing arm 372 are arranged in central symmetry with the center of the rotating disk 37 as the center of symmetry. The first swing arm 371 and the second swing arm 372 serve as the force bearing points of the output torque of the rotating disk 37, and the structure is arranged, so that the force bearing points on the rotating disk 37 are dispersed as much as possible and are not easy to fatigue fracture.

As for the arrangement positions of the first swing arm 371 and the second swing arm 372 on the rotating disk 37, the arrangement is not limited to the above-mentioned arrangement manner of central symmetry, and in other embodiments, the first swing arm 371 and the second swing arm 372 may be arranged at other positions on the peripheral side of the rotating disk 37, for example, the center angle of the first swing arm 371 and the second swing arm 372 at the positions on the peripheral side along the rotating disk 37 is 30 °, 60 ° or 90 °, which is not enumerated here.

In some embodiments, the rotating plate 37 and the first and

second swing arms

371 and 372 are made of metal materials resistant to fatigue, so as to improve the overall service life of the power supply device 30.

In some embodiments, as shown in fig. 10, the rotating disc 37 is provided with a first clearance groove 373 and a second clearance groove 374, when the transmission shaft 31 rotates in the first direction, the second swing arm 372 can swing relative to the rotating disc 37 into the second clearance groove 374 under the abutting of the second limiting portion 341 until the second swing arm 372 passes the second limiting portion 341, the second swing arm 372 extends out of the peripheral side of the rotating disc 37 from the second clearance groove 374, when the transmission shaft 31 rotates in the second direction, the first swing arm 371 can swing relative to the rotating disc 37 into the first clearance groove 373 under the abutting of the first limiting portion 331 until the first swing arm 371 passes the first limiting portion 331, and the first swing arm 371 extends out of the peripheral side of the rotating disc 37 from the second clearance groove 374.

In some embodiments, elastic members (not shown) are disposed between the first swing arm 371 and the rotating disk 37 and between the second swing arm 372 and the rotating disk 37, so that the first swing arm 371 and the second swing arm 372 respectively extend out of the peripheral side of the rotating disk 37 under the elastic force of the corresponding elastic members, and with this structure, the first swing arm 371 and the second swing arm 372 can adaptively drive the corresponding first driving wheel 33 and the corresponding second driving wheel 34 when the rotating disk 37 rotates in different directions, and do not interfere with each other. Specifically, as the rudder 32 is inertially swung about the axis of the transmission shaft 31, the first swing arm 371 and the second swing arm 372 alternately act at this time because the swinging direction of the rudder 32 is repeatedly switched, so that the operation of rotating the first transmission wheel 33 with the rotating disk 37 and the operation of rotating the second transmission wheel 34 with the rotating disk 37 are alternately performed.

The elastic member includes at least one of an extension spring, a compression spring, or a torsion spring.

In some embodiments, a transparent cover 20a is installed on the housing 20, and at least a portion of the power supply device 30 is opposite to the transparent cover 20a, so that the power supply device 30 can be observed through the transparent cover 20a to add to the technological sense of the electronic device 100. The material of the transparent cover 20a is not limited herein, and for example, the material of the transparent cover 20a may be transparent plastic or transparent glass.

The transparent cover 20a may protrude from the outer surface of the housing 20, or may be flush with the surface of the housing 20, which is not limited herein.

In some embodiments, as shown in fig. 3 and 4, a decorative ring 101 may be disposed on the housing 20, and the transparent cover 20a is mounted on the decorative ring 101, so that the overall appearance of the electronic device 100 is better.
